Abstract
This invention is a mobile exercising apparatus which promotes cardiovascular exercise yet minimizes impact to critical joints. A frame supports of pair of reciprocating members (40) which are displaced generally horizontally (100) along the frame at one end, yet reciprocate in a circular motion (102) at the other through a coupling system attached to the frame. Structure is included which orients the foot of the user at a preferred acute angular orientation and permits each foot to move in a generally elliptical path (102) during exercise, and drive a wheel (56) whereby propelling the apparatus. This allows simulation of walking or running without impact. The device may include linkage to facilitate a corresponding upper body exercise involving movement of the arm in which case each hand of the user is displaced along an arcuate path.
Description
WO 97t07860 1 PCT/U',,'/~5199 ~O~SILE EXERCISE APPARATUS
The yl~_.lt. invention relates to a human povv~rcd mobile exercise device; More particular, the i-lo~,Lion enables the user to move his feet in an ovate or near elliptic pattern driving at least one wheel of a mobile exercise apparatus.
Running has long been a popular form of exercise. How~,~, many cannot tolerate the imp~t loading that occurs on heel strike with the ground. Thel~ore, the need exists for a mobile exercise device which simulates the motion and feel of running without the imp~
Prior art human pu~ ;l mobile exercise devices do not allow the user to move through a natural pattern that simulates running. These devices force the user to move his legs primarily through a vertical pumping motion such as in stair climbing and do not simulate the foot motion of running. See, for example, U.S. Patents Nos. 4,053,173;
4,379,566; and 4,456,276.
While prior art stationary exercise devices exist which do allow an ovate or near elliptic foot motion (see, for example, U.S. patents Nos. 5,242,343; 5,299,993;
5,383,829; and 5,423,729), such devices cannot be readily modified to accommodate human powered mobile exercise because of their inherent lengt-h and mechanical configuration. Further, prior art stationaTy exercise devices do not allow control of foot pedal angle during the ovate or near elliptic foot motion.
Hence, the need exists for a mobile exercise ~s..;.t~-~ which provides the physical benefits of running without impact.
Briefly, the invention relates to a human powered running machine. A frame is provided which includes a base portion and a top port:ion. The base portion is supported by at least two wheels. A coupling member is attached to the frame which includes a sprocket defining a pivot axis. Two reciprocating members are positioned in spaced relationship to the base portion of the frame. One end of each reciprocating member is adapted for linear movement substantially p~r~ l with the floor. The end of each of the reciprocating members being linearly displaced contacts the base portion of the frame.
The other end of each reciprocating member is attached, directly or indirectly, to the sprocket of the coupling member. In this manner, rotation of the sprocket rotates one WO 97/07860 PCT/U~G/~5199 end of eadh r~ locating member in a circular moffon while the other end of each reciprocating moves in a substantially linear manner. Means are also included for rotatably engaging the sprodcet of the coupling member with at least one wheel of the frame. This translates the rotational energy of the sprodcet to at least one of the wheels to propel the frame Çolw~d.
Means are also induded for orienting the bottom of the feet of the user so that each foot follows an ovate or near elliptic path during the operation of the apparatus.
Such orienting means may include a linkage assembly for eadh reciprocating member.
Eadh such linkage assembly comprises at least one link whidh is pivotally connected proximal one end ~L,._ n the two ends of a corresponding reciprocating member, dosest to that end of the reciprocating member which is being displaced along the frame. In the ~rcf~lcd embodiment, each linkage ~cst-mhly includes a second link whidh is pivotally connected to the second end of the first link The second link is then pivotally restrained to the top portion of the frame plo~i...~te its other end.
In an alternate embodiment, each linkage ~cs~omhly includes a single foot member.
One end of each foot member is pivotally co~necte-l to a c~ sponding reciprocating member, closest to that end of the reciprocating m~mh~r being displaced along the frame and the other end of eadh foot member consists of a camming surface whidh engages a roller fi~ed to the frame. The camming surface serves to control foot pedal angle.
In another ~ltPrn~fe embodiment, one end of each foot member is pivotally connected to a coll~ponding reciprocating member, dosest to that end of the lc~i~rocating member being displaced along the frame, and the other end is restrained within a tradk whid may be straight or curved and which is attadhed to the frame.
In yet another alt~rn~te embodiment, the base portion of the frame indudes a curved section which acts as a ~mming surface to control the shape of the ovate foot path by influencing the lateral movement of the roller and of eadh reciprocating member.
In yet a further ~lt~n~te embodiment, eadh linkage ~ss~omhly indudes a first andsecond link. Ead~ sud~ first link is pivotally connected prc,xill-al one end between the two ends of a coll~onding rccipi-~cating member, dosest to that end of the reciprocating member whidh is being displaced along the frame. Eadh such second link is pivota~1y connected to the second end of the first linlc, and each such second link is then pivotally restrained to the top portion of the frame yr~)x;~ te its other end.
Hu.._~r~, the second end of each second link also includes a handle portion which is to be grabbed by the user and os~ t~-l in a backward/forward motion.
In yet another further altPrn~te embodiment, each such linkage ~.cs~mhly comprises a l~.i~,r~xating member and a foot platform attached thereto yl~x~ te that end of the re~iyrocating member being displaced along the frame. The foot platform may be angularly adjustable providing a yler~l.1 orientation for muscle development while the feet of the user fo~~ow a yr~r~l.d closed generally e~1iptical anatomical path.
The more i~llyol ant features of this invention have been sllmm~ri7~-1 rather broadly in order that the ~et~ile~ nption may be better understood. There are, of course, additional features of the invention which wi~~ be ~l~oc~rihed hereafter and which wi~~ also form the subject of the c~aims appended hereto.

Figs. 8a-8f are various a~ternate embodiments of the foot platform of the embodiment shown in Fig. 7.
Referring to Figs. 1 and 2, a frame 10 is shown comprising a base portion 12 anda top portion 14. Referring briefly to Fig. 2, the frame 10 comprises two bottom CA 02229552 l998-02-l3 WO 97/07860 4 PCT/U' ,~ '05199 portions 12a and 12b. In essence, the lower portion of the frame is comprised of two sPr~r~te bents "a" and "b". Obviously, variations can be made to frame 10 as disclosed without d~al Ling from the spirit of the invention. A coupling system 20 is fixed relative to the frame and comprises a sprocket 22, cranlc members 24, and chain 30. Two reciprocating members 32 are positioned in the lower p~ luLy of frame 10. Each cating member 32 has one end 34 which is adapted to move laterally in a substantially linear direction as shown in Fig. 1 by arrow 100. A roller 36 is mounted at each end 34 of each ~ ocating member 32 and is adapted, as shown in Fig. 1, to ride on base portion 12 of frarne 10. The other end 38 of each ,~ipl.~cating member 32 is pivotally connected to one end of a crank 24. The other end of each crank 24 is attached to sprocket 22 at the pivot axis 26 of coupling system 20. The pivot axis 26 is the axis about which sprocket 22 rotates. Chain 30 is routed toward the rear of base portion 12 of frame 10 by idler gears 52 attached to base portion 12 by base 53.The frame is supported by at least two wheels 56 and 64. Rear wheel 56 includes a sprocket 54 which is fixed to an axle 57 that is secured to the rear of base porffon 12.
Front wheel 64 includes an axle 63 which is secured to a fork 62. Fork 62 is attached to a rotatable steering tube 60 which passes through top portion 16. Handlebar 58 is :Itt~rhed to steering tube 60. Referring still to Fig. 1, chain 30 is routed past idler gears 52 and circ-1rncrnhes rear sprocket 54.
In the ~r~ cd embodiment, the present invenffon also includes two foot members, or contact members,40. Each foot member 40 is pivotally attached t,loxiT..~te a first end 42 through a pinned connection 44 to the ~c~i~rocaffng arm 32. A foot pad 50 is attached to the top surface of each foot member 40 at its first end 42. Each foot member 40 is pivotally attached at its other end 46 to a positioning member 48. Each posiffoning member 48 is also pivotally ~tt~rhe~l pioxilllal its other end to the top portion 16 of frame 10. Rcfer~ing to Fig.2, it can be easily seen that frame 10 comprises dual base portions 12a/12b. Furthermore, it can be seen that reciprocating members 32, foot members 40, and positioning members 48 provide identical dual systems; eachsystem resffng on a base porffon 12a or 12b of the frame and each arranged to accommodate one foot of the user.
W097/07860 5 PCT~S96/05199 In the operation of the ~ref~.~1 embodiment, the user "U" places his right foot on the right pedal and pushes off with his left foot at which time he places his left foot on the pedal. The user then commences an elliptic or an ovate motion of his feet as in running or walking. This motion results in the displacement of first ends 34 of each caling member 32 in the direction of arrow 100. Similarly, a circ~ ting motion occurs at the second end 38 of each r~ r~cating member 32 about pivot axis 26.
Huwc:~,~, at points between the opposite ends 34 and 38 of each l .:ipl~cating member 32, the motion gradually changes from a circular motion (at ends 38) to a linear motion at the ends 34. This geon~etric transition occurs in the form of an ovate or near elliptic path 102. Pinned connection 44 and foot pad 50 move through the above described ovate path. Foot member end 46 moves through an arcuate path defined by the l~lo~Lillg arcuate motion of positioning member 48 thereby controlling the angle of foot member 40 and foot pad 50. Rotation of crank 24 and drive sprocket 22 causes chain 30 to drive rear sprocket 54 and rear wheel 56 thus propelling the apparatus folw~rd.
Those skilled in the art will appreciate that traditional bicycle planetary or derailleur gear shift systems are easily adapted to the running machine. Although the figures show this embodiment with two wheels, those skilled in the art -will recognize that three or four wheels can be lltili7e~1 in either a tricycle or quadracycle configuration.
Referring now to Fig. 3, an alternate embodiment of the present invention is shown. For this embo-liment, identical two-digit r~ence numerals will be used todesignate similar structure found in the ~ d embodiment but with a 100 series pref~ Frame 1 10 again comprises a base portion 1 12 and a top portion 1 16. A coupler system I20 is also provided which is identical in structure and function to coupling system 20 of the ~r~l~d embodiment (Figs. 1-2). This altt~ t~ embodiment also ~ includes a pair of reciprocating members I32, each having a first end I34 which moves linearly in the direction of arrow 200 by means of rollers 136. Each reciprocating member 132 includes a second end 138 pivotally attached to one end of a cranlc 124.
In this alternate embodiment, two foot members 140 are included having a foot portion 150. Each foot member 140 is pivotally connected at a pinned connection 144 WO 97t07860 6 PCT/US96/05199 te first end 142 of a foot member 140 to a corresponding reciprocating member 132. The r~,lw~ and upper portion 113 of the foot member 140 colll~lises a ~mming portion 115 which may be cuIved as shown by phantom lines 166. A roller 146, which is se.u,ed to upper frame 116, engages the upper surface of the r~mming portion 115 of the foot member 140 during the operation of the present invention. Thus, each roller 146 serves to vertically ~ Lin the t~mming portion 115 of each member 140.
In the operation of this alternate embodiment, the user initiates an ovate or near elliptic motion of his feet. This foot motion causes the ends 134 of each Lc~i~locating member to move in a linear motion in the direction of a~w 200 while ends 138 of each Lc~i~locating mtomhtor 132 move in a circular motion about pivot axis 126. Pinned connection 144 and foot pad 150 move through an ovate or near elliptic path 202, and the angle of the foot pad 150 is controlled by the ~ g surface 115 engaging roller 146. The profile of the ~ ;-.. i.lg surface 115 is S~lP~t'(1 SO as to achieve desired foot pad angles.
Referring now to Fig. 4, another alt.orn~te embodiment of the present invention is shown. As before, similar parts will be designated by the same two-digit r~fc~ ce numeral as shown in the ~ ~l embodiment but now with a 200 series prefi~. Frame 210 comprises a lower portion 212 and a top portion 216. A coupling system 220 is in~ t~lecl having identical components of the coupling system 20 described above for the pnf~lcd embodiment. Further, coupling system 220 p~rOll~ls in an identical manner to coupling system 20 described above for the ~lcf~lcd embodiment.
A pair of reciprocating members 232 are also iI~ tt~ , each having a first end 234 on which rollers 236 are mounted. The second end 238 of each reciprocating member 232 is pivotally connected to one end of each crank 224. Two foot members 240 are included in this alternate embodiment, each being pivotally connected pr ~xim~te first end 242 at a pinned connection 244 to a cc,lles~onding reciprocating member 232.Each foot m~mh~r 240 also includes a foot pad 250 ~tt~e-l to the top surface of each foot member 240 at first end 242. In this embodiment, a roller 246 is ~tt~h~l to each foot member 240 at its second end 245. Each roller 246 engages a track 213 which may be curved as shown by phantom lines 268. Track 213 is attached to top portion 216 of the frame. Thus, each track 213 guides the second end 245 of each foot mPmher 240 by means of roller 246.
In the operation of this ~lt~ te embodiment, the user initiates an ovate or neareUiptic motion 302 of his feet. This foot motion causes ends 234 of each reciprocating member 232 to move in a linear motion in the direction of arrow 300 and ends 238 of each reciprocating mPmh~r 232 move in a ~ircular motion about pivot axis 226. Pinned ronnection 144 and foot pad 150 move through an ovate or near elliptic path, and the angle of the foot pad 150 is controlled by the roller 246 which engages track 213. The profile of track 213 is selected so as to achieve the desired foot pad angles.
Referring now to Fig. 5, yet another alternate embodiment of the yrcs~lt invention is shown. As before, similar parts will be designated by the same two-digit lcfcrc~lce numeral as shown in the ylercllc;l embodiment but now with a 300 series pr&. Frame 310 again co,nylises a base portion 312 and a top portion 316. In this alternate embodiment, a portion of base portion 312 includes a curved profile 313 yl~ te that portion of the base in contact with rollers 336 of lc iyn~cating members 332. A coupling system 320 is including having identical components of the coupling system 20 described above for the yl~r~led embodiment. Further, coupling system 320 y~r.,lll~s in an identical manner to coupling system 20 described above for the yrcrc~l~d embodiment. Each re~iylucating member 332 has one end 334 which is adapted to move lateraUy. A roller 336 is mounted at cach end 334 of each re iyl~cating member 332 and is adapted, as shown in Fig.6, to ride on curved profik 313 of base portion 312 of frame 310.
This alternate embodiment also includes two foot membcrs, or contact members, 340. Each foot member 340 is pivotaUy attached pro~rim~te a first end 342 through a pinned connection 344 to each reciprocating arm 332. A foot pad 350 is attached to the top surface of each foot member 340 at its first end 342. Each foot member 340 is pivotally attached at its other end 346 to positioning member 348. Each positioning member 348 is also pivotaUy attached proximal its other end to top portion 316 of frame 310.
In the operation of this alternate embodiment, the user's feet move in a pre-l.1....-..led closed ovate path 402. The curved portion 313 of each base portion 312 acts as a t~mming surface and influences the profile of the closed path 402. In Fig. 6, the profile of the curved portion 313 serves to flatten the lower portion of path 402 which more ~ r~tt~ly sim~ t~c a low speed waL~dng motion. Different profiles for the curved portion 313 may be utilized to best simulate other walking or running speeds.
Referring now to Fig. 6, yet a further alternate embodiment of the present invention is shown. As before, similar parts will be designated by the same two-digit lef~lce numeral as shown in the ~r~c~lcd embodiment but now with a 400 series prefix. Frame 410 again comprises a base portion 412 and a top portion 416. A
coupling system 420 is included having identical components of the coupling system 20 described above for thc ~r.fellcd embodiment. Further, coupling system 420 ~rOlllls in an identical manner to coupling system 20 rl~$~rihed above for the pLcr~l.d embodiment. Each rc~l~,cating member 432 has one end 434 which is adapted to move laterally. A roller 436 is mounted at each end 434 of reciprocating member 432 and is adapted to ride on base portion 412 of frame 410.
This alternate embo~lim~nt also includes two foot members, or contact members, 440. Each foot member 440 is pivotally attached pll-xi...~te a first end 442 through a pinned connection 444 at the reciprocating arm 432. A foot pad 4~0 is attached to the top surface of each foot member 440 at its first end 442. Each foot member 440 is pivotally attached at its other end 446 to arm member 448. Each arm member 448 is pivotally attached ~loxil~al it~s mid-point to the top portion 416 of frame 410. Handles 470 are pivotally coupled to arm members 448 so that the handles can rotate about axes 449. Shrouded cables 474 mechanically couple handles 470 to fork 462 through bellcrank 472. Therefore, as the handles are rotated about axes 449 by the user, the front fork is forced to rotate and steering is effected.
In the operation of this alternate embodiment, the user initiates an ovate or near dliptic motion of his feet. This foot motion causes the ends 434 of each reciprocating member to move in a linear motion in the direction of arrow ~00 and ends 438 of each reciprocating member 432 move in a circular motion about pivot axes 426. Pinned cormection 444 and foot pad 450 move through an ovate or near elliptic path ~02. End 446 of each foot member 440 moves through an arcuate path defined by the le~ ocating arcuate motion of arm member 448 thereby controlling the angle of foot member 440 and foot pad 450. The upper end of arm members 448 and handles 470 also move in an arcuate pattern. The user may simultaneously exercise his upper body by pushing and pulling on the handles 470.
Refsrr~g no~tQEig. ~ ~et~nQther~h~ r~tc ~tnhodi~e~ of the pr~c~
invention is shown. As before, similar parts will be designated by the same two-digit refer~lce numeral as shown in the ~,~r~l~l embodiment but now with a 500 series prefix. Frame 510 again co~ lises a base portion 512 and a top portion 516. A
coupling s~stem 520 is included having identical components of the coupling system 20 ~1~s~nhe-1 above for the ~r~Ç~l~d embodiment. Further, coupling system 520 pc~rolms in an identical manner to coupling system 20 ~les~nhed above for the ~r~f~l.d embodiment. In this alternate embodiment two reciprocating members 532 are shown, each one having an end 534 which is adapted to move substantially laterally along base portion 512. A roller 536 is mounted at each end 534 of each l~ cating member532. In this alternate embodiment a foot contact member 550 is attached to each reciprocating member 532 ~r~xi...~te end 534 of the cc.ll~.~onding reciprocatingmember 532. Each foot contact member 550 includes a foot platform 551 which is used to support and contact directly a foot of the user.
As shown in Fig.7, each foot platform 551 is pl~bly aligned at an acute angle with respect to the longitt.(lin~l axis of the cc~ ponding r~ rocating member 532 which extends from the pivotal connection 537 at the end of the reciprocating member 532 attached to the coupling system 520 to roller 536 at the other end 534 of the corresponding reciprocating member 532. Thus, during use of the embodiment shownin Fig. 7, each foot platform 550 moves through an ovate or near elliptical path 602.
The orientation of platform 551 is arranged so that when it is near the highest position as a~loxi.n~tPly shown by the location of the right foot platform 551r in Fig. 7, platform SSlr is substantially parallel to the ground. This is ~r~e~ble to prevent l~W~l'd tilt of platform 551 as it progresses through path 602. Otherwise, the device may cause excessive loading of the calf muscle. As the right foot of the user moves through the boLLolll of path 602, the right heel lifts, allowing the user to generate more l~Wal'~l thrust thereby expending additional energy to propel the mobile exercise device rOlw~l.
Rcfernng now to Figs. 8a-8f, various alternate embo-lim~ntc of each foot contactmember 550 of Fig. 7 are further illustrated.
With l~spc.L to Fig. 8a, foot contact member 550 comprises a ront~-~t platform 551a pivotaUy connected at end 700 via pivot connection 702 to reciprocating member 532a. A flange or channel m~mher 704 is attached to the base of platform 551 a and in~ les apertures 706. The end of platform 55 l a distal end 700 is supported by brace 708. One end of brace 708 is pivotally attached at pivot point 710 to reciprocating member 532a while the other end of brace 708 is engaged via a pin connection 712through one of ap-lLulcs 706. In this manner, the angle of platform 551a can be adjusted relative to the longitudinal axis of reciprocating member 532a. Such anadjustment can be made to ~~commodate the desired angle of inclination of the user while m~int~ining the ~rcrcll~;l elliptical path 602 of Fig. 7.
Referring now to Fig. 8b, foot contact member 550 as shown in Fig. 7 may comprice an alternate embodiment as shown in Fig. 8b which includes a foot platform 55 lb pivotally mounted at pin connection 716 to nonlinear reciprocating member 532b having a platform support member 714. ~n this embodiment, foot platform 551 b is free to pivot about pin cor~nection 716 enabling the user to freely rotate platform 551 b to any number of ylcrc~d acute angular positions relative to a line or axis extending from one end 537b of ~e~plocating member 532b to its other end 534b. Notwithstanding the angular orientation s~lect~l1 by the user during the cycling motion, platform 551 b will continue to maintain a closed substantially elliptical path 602 as shown in Fig. 7.
~s rlic~lcse~l above, such elliptical movement provides for ~lcfe~ed anatomical response ~nilulluzing damage and injury to the ankles and knees.
Referring now to Fig. 8c, another alternate embodiment of foot contact member 550 as shown in Fig. 7 is depicted. Reciprocating member 532c is generally the same nonlin~r configuration as that of reciprocating member 532b of Fig. 8B except that it indudes apertures 718 adapted to accommodate pin connections 720 which fixedly WO 97/07860 1 1 PcT/u~ 3199 secure platform support member 722. As in the case of Fig. 8b, platform 551c is pivotaUy connected at connection 724 enabling the user to pivot platform 551 c to the desired acute angular orientation. The embodiment shown in Fig. 8c is distinguishable from the embodiment shown in Fig. 8b in that the user may disengage pins 720 andreposition member 722 rclaL~,e to member 532c by i~ ing pins 720 in other ap~ s 718. This changes the profile of closed elliptical path 602. As platform 551 c is moved rearwardly towards roller 536c, elliptical path 602 is fl~ttlonerl thereby deemphasizing vertical movement of each platform 551c. This may be a ~r~ d anatomical pattcrn for some users.
Referring now to Fig. 8d, a further im~ro~,clnent is shown over the embo-lim~nt of Fig.8b. Once again, reciprocating member 532d is nonlinear and includes a platform support member 726 which, through pivotal connection 728, supports one end of platform 551d. The other end of platform 551d is supported by scissor members 732/734. Each scissor member 732 and 734 is pivotally connected to one another at connection 736. The other end of member 732 is pivotaUy connected at connection 730 to foot platform 551d. The other end of member 734 is pivotally connected at connection 738 to the end 534d of re~i~rocating member 532d ~r~,xi.~te roller 536d.
A tensioning member 800 is pivotally attached at one end to member 726 through pin connection 802. The distal portion of member 800 is supported through a bushing arrangement 804 p~ te pin connection 736. A spring 808 is placed over the portion of member 800 distal pin connection 802. A nut and washer arrangement 810 is then secured through a threaded portion on the distal end of member 800 to co~ r~ss spring 808. In this manner, the operation of the embodiment shown in Fig. 8d is generally similar to the embodiment shown in Fig. 8b except that the pivotal motion of platform 551 d is partially restrained by the colllpr~ re nature of spring 808. That is, during ~~ cy~ling motion d~wllw~l pressure through the heel of the user against the rear portion of platform 551d ~ c~nt pin connection 730 serves to compress or close the scissor members 732/734 thereby com~r~sillg spring 808. In this manner, free pivotal movement of platform 551d about pin connection 728 is somewhat restrained eliminating the possibility of any erratic pivotal motion of platform 551 d.
Referring now to the embodiment shown in Fig. 8e, the arrangement therein is substantially identical to the embodiment shown in Fig. 8d except for the substitution of a shoc~damper 820 in place of spring 808 of Fig. 8d. In this manner, shock/damper 820 serves to retard cc~ les~i~,c and tensile forces. Thus, as the user exerts a heel load on platform 551e ~ te pivot connection 740 the com~rer,~ive force serves to CU~ 5 or close scissor members 742 and 744. However, shock/damper 820 inhibits abrupt compr~,si~,e loading of scissor members 742/744 by placing a tensile load on member 830. Similarly, if the user places an ~x es,ive toe load forward of pin connection 750 which serves to raise the heel portion of platform 55 le, shock/damper 820 serves to inhibit a rapid extension of scissor members 742/744 by placing a compressive load on member 830. In this manner, pivotal motion of platfonn 551e about pin connection 750 is controlled. While pivotal motion is still ~lmi~Led enabling the user to adjust the angle of platform 551 e to the ~r~c~d acute angular orientation, the overall movement of both foot plaLlc,lllls remains on the generally elliptical path 602 of Fig.7.
Finally, r~c~lillg to Fig. 8f, an alternate embodiment is shown of a nonlinear reciprocating member 536f which is similar in configuration to the embodiment shown in Fig. 8b. The primary ~c~Lion with respect to the embodiment of Fig. 8b is theinclusion of a flange 860 attached to the bo~Lc~ of platform 551f having apertures 870.
Platfonm support member 872 includes an aperture through which a pin 875 passes providing pivotal movement of platform 551f thlo~,h one aperture 870 relative tomember 872. The embodiment shown in Fig. 8f is a modification over the embodiment shown in Fig. 8b in that it permits the user to select more precisely the pivot point of platform 551f relative to its longitudinal position on lc i~l~,cating member 532f. This may have certain benefits by increasing or decreasing the amount of calf musde involved in the exercise since pivotal orientation will be varied requiring lower leg muscle control to maintain the proper acute angular orientation as the foot platform 551f movesthrough substantially elliptical path 602.
Obviously, modifications and alterations to the preferred embodiment disclosed herein will be a~al~t to those skilled in the art in view of this disclosure. ~uw~vel, it is intended that all such variations and modifications fall within the spirit and scope of this ill~,cll~ion as ~l~ime~l
The yl~_.lt. invention relates to a human povv~rcd mobile exercise device; More particular, the i-lo~,Lion enables the user to move his feet in an ovate or near elliptic pattern driving at least one wheel of a mobile exercise apparatus.
Running has long been a popular form of exercise. How~,~, many cannot tolerate the imp~t loading that occurs on heel strike with the ground. Thel~ore, the need exists for a mobile exercise device which simulates the motion and feel of running without the imp~
Prior art human pu~ ;l mobile exercise devices do not allow the user to move through a natural pattern that simulates running. These devices force the user to move his legs primarily through a vertical pumping motion such as in stair climbing and do not simulate the foot motion of running. See, for example, U.S. Patents Nos. 4,053,173;
4,379,566; and 4,456,276.
While prior art stationary exercise devices exist which do allow an ovate or near elliptic foot motion (see, for example, U.S. patents Nos. 5,242,343; 5,299,993;
5,383,829; and 5,423,729), such devices cannot be readily modified to accommodate human powered mobile exercise because of their inherent lengt-h and mechanical configuration. Further, prior art stationaTy exercise devices do not allow control of foot pedal angle during the ovate or near elliptic foot motion.
Hence, the need exists for a mobile exercise ~s..;.t~-~ which provides the physical benefits of running without impact.
Briefly, the invention relates to a human powered running machine. A frame is provided which includes a base portion and a top port:ion. The base portion is supported by at least two wheels. A coupling member is attached to the frame which includes a sprocket defining a pivot axis. Two reciprocating members are positioned in spaced relationship to the base portion of the frame. One end of each reciprocating member is adapted for linear movement substantially p~r~ l with the floor. The end of each of the reciprocating members being linearly displaced contacts the base portion of the frame.
The other end of each reciprocating member is attached, directly or indirectly, to the sprocket of the coupling member. In this manner, rotation of the sprocket rotates one WO 97/07860 PCT/U~G/~5199 end of eadh r~ locating member in a circular moffon while the other end of each reciprocating moves in a substantially linear manner. Means are also included for rotatably engaging the sprodcet of the coupling member with at least one wheel of the frame. This translates the rotational energy of the sprodcet to at least one of the wheels to propel the frame Çolw~d.
Means are also induded for orienting the bottom of the feet of the user so that each foot follows an ovate or near elliptic path during the operation of the apparatus.
Such orienting means may include a linkage assembly for eadh reciprocating member.
Eadh such linkage assembly comprises at least one link whidh is pivotally connected proximal one end ~L,._ n the two ends of a corresponding reciprocating member, dosest to that end of the reciprocating member which is being displaced along the frame. In the ~rcf~lcd embodiment, each linkage ~cst-mhly includes a second link whidh is pivotally connected to the second end of the first link The second link is then pivotally restrained to the top portion of the frame plo~i...~te its other end.
In an alternate embodiment, each linkage ~cs~omhly includes a single foot member.
One end of each foot member is pivotally co~necte-l to a c~ sponding reciprocating member, closest to that end of the reciprocating m~mh~r being displaced along the frame and the other end of eadh foot member consists of a camming surface whidh engages a roller fi~ed to the frame. The camming surface serves to control foot pedal angle.
In another ~ltPrn~fe embodiment, one end of each foot member is pivotally connected to a coll~ponding reciprocating member, dosest to that end of the lc~i~rocating member being displaced along the frame, and the other end is restrained within a tradk whid may be straight or curved and which is attadhed to the frame.
In yet another alt~rn~te embodiment, the base portion of the frame indudes a curved section which acts as a ~mming surface to control the shape of the ovate foot path by influencing the lateral movement of the roller and of eadh reciprocating member.
In yet a further ~lt~n~te embodiment, eadh linkage ~ss~omhly indudes a first andsecond link. Ead~ sud~ first link is pivotally connected prc,xill-al one end between the two ends of a coll~onding rccipi-~cating member, dosest to that end of the reciprocating member whidh is being displaced along the frame. Eadh such second link is pivota~1y connected to the second end of the first linlc, and each such second link is then pivotally restrained to the top portion of the frame yr~)x;~ te its other end.
Hu.._~r~, the second end of each second link also includes a handle portion which is to be grabbed by the user and os~ t~-l in a backward/forward motion.
In yet another further altPrn~te embodiment, each such linkage ~.cs~mhly comprises a l~.i~,r~xating member and a foot platform attached thereto yl~x~ te that end of the re~iyrocating member being displaced along the frame. The foot platform may be angularly adjustable providing a yler~l.1 orientation for muscle development while the feet of the user fo~~ow a yr~r~l.d closed generally e~1iptical anatomical path.
The more i~llyol ant features of this invention have been sllmm~ri7~-1 rather broadly in order that the ~et~ile~ nption may be better understood. There are, of course, additional features of the invention which wi~~ be ~l~oc~rihed hereafter and which wi~~ also form the subject of the c~aims appended hereto.

Figs. 8a-8f are various a~ternate embodiments of the foot platform of the embodiment shown in Fig. 7.
Referring to Figs. 1 and 2, a frame 10 is shown comprising a base portion 12 anda top portion 14. Referring briefly to Fig. 2, the frame 10 comprises two bottom CA 02229552 l998-02-l3 WO 97/07860 4 PCT/U' ,~ '05199 portions 12a and 12b. In essence, the lower portion of the frame is comprised of two sPr~r~te bents "a" and "b". Obviously, variations can be made to frame 10 as disclosed without d~al Ling from the spirit of the invention. A coupling system 20 is fixed relative to the frame and comprises a sprocket 22, cranlc members 24, and chain 30. Two reciprocating members 32 are positioned in the lower p~ luLy of frame 10. Each cating member 32 has one end 34 which is adapted to move laterally in a substantially linear direction as shown in Fig. 1 by arrow 100. A roller 36 is mounted at each end 34 of each ~ ocating member 32 and is adapted, as shown in Fig. 1, to ride on base portion 12 of frarne 10. The other end 38 of each ,~ipl.~cating member 32 is pivotally connected to one end of a crank 24. The other end of each crank 24 is attached to sprocket 22 at the pivot axis 26 of coupling system 20. The pivot axis 26 is the axis about which sprocket 22 rotates. Chain 30 is routed toward the rear of base portion 12 of frame 10 by idler gears 52 attached to base portion 12 by base 53.The frame is supported by at least two wheels 56 and 64. Rear wheel 56 includes a sprocket 54 which is fixed to an axle 57 that is secured to the rear of base porffon 12.
Front wheel 64 includes an axle 63 which is secured to a fork 62. Fork 62 is attached to a rotatable steering tube 60 which passes through top portion 16. Handlebar 58 is :Itt~rhed to steering tube 60. Referring still to Fig. 1, chain 30 is routed past idler gears 52 and circ-1rncrnhes rear sprocket 54.
In the ~r~ cd embodiment, the present invenffon also includes two foot members, or contact members,40. Each foot member 40 is pivotally attached t,loxiT..~te a first end 42 through a pinned connection 44 to the ~c~i~rocaffng arm 32. A foot pad 50 is attached to the top surface of each foot member 40 at its first end 42. Each foot member 40 is pivotally attached at its other end 46 to a positioning member 48. Each posiffoning member 48 is also pivotally ~tt~rhe~l pioxilllal its other end to the top portion 16 of frame 10. Rcfer~ing to Fig.2, it can be easily seen that frame 10 comprises dual base portions 12a/12b. Furthermore, it can be seen that reciprocating members 32, foot members 40, and positioning members 48 provide identical dual systems; eachsystem resffng on a base porffon 12a or 12b of the frame and each arranged to accommodate one foot of the user.
W097/07860 5 PCT~S96/05199 In the operation of the ~ref~.~1 embodiment, the user "U" places his right foot on the right pedal and pushes off with his left foot at which time he places his left foot on the pedal. The user then commences an elliptic or an ovate motion of his feet as in running or walking. This motion results in the displacement of first ends 34 of each caling member 32 in the direction of arrow 100. Similarly, a circ~ ting motion occurs at the second end 38 of each r~ r~cating member 32 about pivot axis 26.
Huwc:~,~, at points between the opposite ends 34 and 38 of each l .:ipl~cating member 32, the motion gradually changes from a circular motion (at ends 38) to a linear motion at the ends 34. This geon~etric transition occurs in the form of an ovate or near elliptic path 102. Pinned connection 44 and foot pad 50 move through the above described ovate path. Foot member end 46 moves through an arcuate path defined by the l~lo~Lillg arcuate motion of positioning member 48 thereby controlling the angle of foot member 40 and foot pad 50. Rotation of crank 24 and drive sprocket 22 causes chain 30 to drive rear sprocket 54 and rear wheel 56 thus propelling the apparatus folw~rd.
Those skilled in the art will appreciate that traditional bicycle planetary or derailleur gear shift systems are easily adapted to the running machine. Although the figures show this embodiment with two wheels, those skilled in the art -will recognize that three or four wheels can be lltili7e~1 in either a tricycle or quadracycle configuration.
Referring now to Fig. 3, an alternate embodiment of the present invention is shown. For this embo-liment, identical two-digit r~ence numerals will be used todesignate similar structure found in the ~ d embodiment but with a 100 series pref~ Frame 1 10 again comprises a base portion 1 12 and a top portion 1 16. A coupler system I20 is also provided which is identical in structure and function to coupling system 20 of the ~r~l~d embodiment (Figs. 1-2). This altt~ t~ embodiment also ~ includes a pair of reciprocating members I32, each having a first end I34 which moves linearly in the direction of arrow 200 by means of rollers 136. Each reciprocating member 132 includes a second end 138 pivotally attached to one end of a cranlc 124.
In this alternate embodiment, two foot members 140 are included having a foot portion 150. Each foot member 140 is pivotally connected at a pinned connection 144 WO 97t07860 6 PCT/US96/05199 te first end 142 of a foot member 140 to a corresponding reciprocating member 132. The r~,lw~ and upper portion 113 of the foot member 140 colll~lises a ~mming portion 115 which may be cuIved as shown by phantom lines 166. A roller 146, which is se.u,ed to upper frame 116, engages the upper surface of the r~mming portion 115 of the foot member 140 during the operation of the present invention. Thus, each roller 146 serves to vertically ~ Lin the t~mming portion 115 of each member 140.
In the operation of this alternate embodiment, the user initiates an ovate or near elliptic motion of his feet. This foot motion causes the ends 134 of each Lc~i~locating member to move in a linear motion in the direction of a~w 200 while ends 138 of each Lc~i~locating mtomhtor 132 move in a circular motion about pivot axis 126. Pinned connection 144 and foot pad 150 move through an ovate or near elliptic path 202, and the angle of the foot pad 150 is controlled by the ~ g surface 115 engaging roller 146. The profile of the ~ ;-.. i.lg surface 115 is S~lP~t'(1 SO as to achieve desired foot pad angles.
Referring now to Fig. 4, another alt.orn~te embodiment of the present invention is shown. As before, similar parts will be designated by the same two-digit r~fc~ ce numeral as shown in the ~ ~l embodiment but now with a 200 series prefi~. Frame 210 comprises a lower portion 212 and a top portion 216. A coupling system 220 is in~ t~lecl having identical components of the coupling system 20 described above for the pnf~lcd embodiment. Further, coupling system 220 p~rOll~ls in an identical manner to coupling system 20 described above for the ~lcf~lcd embodiment.
A pair of reciprocating members 232 are also iI~ tt~ , each having a first end 234 on which rollers 236 are mounted. The second end 238 of each reciprocating member 232 is pivotally connected to one end of each crank 224. Two foot members 240 are included in this alternate embodiment, each being pivotally connected pr ~xim~te first end 242 at a pinned connection 244 to a cc,lles~onding reciprocating member 232.Each foot m~mh~r 240 also includes a foot pad 250 ~tt~e-l to the top surface of each foot member 240 at first end 242. In this embodiment, a roller 246 is ~tt~h~l to each foot member 240 at its second end 245. Each roller 246 engages a track 213 which may be curved as shown by phantom lines 268. Track 213 is attached to top portion 216 of the frame. Thus, each track 213 guides the second end 245 of each foot mPmher 240 by means of roller 246.
In the operation of this ~lt~ te embodiment, the user initiates an ovate or neareUiptic motion 302 of his feet. This foot motion causes ends 234 of each reciprocating member 232 to move in a linear motion in the direction of arrow 300 and ends 238 of each reciprocating mPmh~r 232 move in a ~ircular motion about pivot axis 226. Pinned ronnection 144 and foot pad 150 move through an ovate or near elliptic path, and the angle of the foot pad 150 is controlled by the roller 246 which engages track 213. The profile of track 213 is selected so as to achieve the desired foot pad angles.
Referring now to Fig. 5, yet another alternate embodiment of the yrcs~lt invention is shown. As before, similar parts will be designated by the same two-digit lcfcrc~lce numeral as shown in the ylercllc;l embodiment but now with a 300 series pr&. Frame 310 again co,nylises a base portion 312 and a top portion 316. In this alternate embodiment, a portion of base portion 312 includes a curved profile 313 yl~ te that portion of the base in contact with rollers 336 of lc iyn~cating members 332. A coupling system 320 is including having identical components of the coupling system 20 described above for the yl~r~led embodiment. Further, coupling system 320 y~r.,lll~s in an identical manner to coupling system 20 described above for the yrcrc~l~d embodiment. Each re~iylucating member 332 has one end 334 which is adapted to move lateraUy. A roller 336 is mounted at cach end 334 of each re iyl~cating member 332 and is adapted, as shown in Fig.6, to ride on curved profik 313 of base portion 312 of frame 310.
This alternate embodiment also includes two foot membcrs, or contact members, 340. Each foot member 340 is pivotaUy attached pro~rim~te a first end 342 through a pinned connection 344 to each reciprocating arm 332. A foot pad 350 is attached to the top surface of each foot member 340 at its first end 342. Each foot member 340 is pivotally attached at its other end 346 to positioning member 348. Each positioning member 348 is also pivotaUy attached proximal its other end to top portion 316 of frame 310.
In the operation of this alternate embodiment, the user's feet move in a pre-l.1....-..led closed ovate path 402. The curved portion 313 of each base portion 312 acts as a t~mming surface and influences the profile of the closed path 402. In Fig. 6, the profile of the curved portion 313 serves to flatten the lower portion of path 402 which more ~ r~tt~ly sim~ t~c a low speed waL~dng motion. Different profiles for the curved portion 313 may be utilized to best simulate other walking or running speeds.
Referring now to Fig. 6, yet a further alternate embodiment of the present invention is shown. As before, similar parts will be designated by the same two-digit lef~lce numeral as shown in the ~r~c~lcd embodiment but now with a 400 series prefix. Frame 410 again comprises a base portion 412 and a top portion 416. A
coupling system 420 is included having identical components of the coupling system 20 described above for thc ~r.fellcd embodiment. Further, coupling system 420 ~rOlllls in an identical manner to coupling system 20 rl~$~rihed above for the pLcr~l.d embodiment. Each rc~l~,cating member 432 has one end 434 which is adapted to move laterally. A roller 436 is mounted at each end 434 of reciprocating member 432 and is adapted to ride on base portion 412 of frame 410.
This alternate embo~lim~nt also includes two foot members, or contact members, 440. Each foot member 440 is pivotally attached pll-xi...~te a first end 442 through a pinned connection 444 at the reciprocating arm 432. A foot pad 4~0 is attached to the top surface of each foot member 440 at its first end 442. Each foot member 440 is pivotally attached at its other end 446 to arm member 448. Each arm member 448 is pivotally attached ~loxil~al it~s mid-point to the top portion 416 of frame 410. Handles 470 are pivotally coupled to arm members 448 so that the handles can rotate about axes 449. Shrouded cables 474 mechanically couple handles 470 to fork 462 through bellcrank 472. Therefore, as the handles are rotated about axes 449 by the user, the front fork is forced to rotate and steering is effected.
In the operation of this alternate embodiment, the user initiates an ovate or near dliptic motion of his feet. This foot motion causes the ends 434 of each reciprocating member to move in a linear motion in the direction of arrow ~00 and ends 438 of each reciprocating member 432 move in a circular motion about pivot axes 426. Pinned cormection 444 and foot pad 450 move through an ovate or near elliptic path ~02. End 446 of each foot member 440 moves through an arcuate path defined by the le~ ocating arcuate motion of arm member 448 thereby controlling the angle of foot member 440 and foot pad 450. The upper end of arm members 448 and handles 470 also move in an arcuate pattern. The user may simultaneously exercise his upper body by pushing and pulling on the handles 470.
Refsrr~g no~tQEig. ~ ~et~nQther~h~ r~tc ~tnhodi~e~ of the pr~c~
invention is shown. As before, similar parts will be designated by the same two-digit refer~lce numeral as shown in the ~,~r~l~l embodiment but now with a 500 series prefix. Frame 510 again co~ lises a base portion 512 and a top portion 516. A
coupling s~stem 520 is included having identical components of the coupling system 20 ~1~s~nhe-1 above for the ~r~Ç~l~d embodiment. Further, coupling system 520 pc~rolms in an identical manner to coupling system 20 ~les~nhed above for the ~r~f~l.d embodiment. In this alternate embodiment two reciprocating members 532 are shown, each one having an end 534 which is adapted to move substantially laterally along base portion 512. A roller 536 is mounted at each end 534 of each l~ cating member532. In this alternate embodiment a foot contact member 550 is attached to each reciprocating member 532 ~r~xi...~te end 534 of the cc.ll~.~onding reciprocatingmember 532. Each foot contact member 550 includes a foot platform 551 which is used to support and contact directly a foot of the user.
As shown in Fig.7, each foot platform 551 is pl~bly aligned at an acute angle with respect to the longitt.(lin~l axis of the cc~ ponding r~ rocating member 532 which extends from the pivotal connection 537 at the end of the reciprocating member 532 attached to the coupling system 520 to roller 536 at the other end 534 of the corresponding reciprocating member 532. Thus, during use of the embodiment shownin Fig. 7, each foot platform 550 moves through an ovate or near elliptical path 602.
The orientation of platform 551 is arranged so that when it is near the highest position as a~loxi.n~tPly shown by the location of the right foot platform 551r in Fig. 7, platform SSlr is substantially parallel to the ground. This is ~r~e~ble to prevent l~W~l'd tilt of platform 551 as it progresses through path 602. Otherwise, the device may cause excessive loading of the calf muscle. As the right foot of the user moves through the boLLolll of path 602, the right heel lifts, allowing the user to generate more l~Wal'~l thrust thereby expending additional energy to propel the mobile exercise device rOlw~l.
Rcfernng now to Figs. 8a-8f, various alternate embo-lim~ntc of each foot contactmember 550 of Fig. 7 are further illustrated.
With l~spc.L to Fig. 8a, foot contact member 550 comprises a ront~-~t platform 551a pivotaUy connected at end 700 via pivot connection 702 to reciprocating member 532a. A flange or channel m~mher 704 is attached to the base of platform 551 a and in~ les apertures 706. The end of platform 55 l a distal end 700 is supported by brace 708. One end of brace 708 is pivotally attached at pivot point 710 to reciprocating member 532a while the other end of brace 708 is engaged via a pin connection 712through one of ap-lLulcs 706. In this manner, the angle of platform 551a can be adjusted relative to the longitudinal axis of reciprocating member 532a. Such anadjustment can be made to ~~commodate the desired angle of inclination of the user while m~int~ining the ~rcrcll~;l elliptical path 602 of Fig. 7.
Referring now to Fig. 8b, foot contact member 550 as shown in Fig. 7 may comprice an alternate embodiment as shown in Fig. 8b which includes a foot platform 55 lb pivotally mounted at pin connection 716 to nonlinear reciprocating member 532b having a platform support member 714. ~n this embodiment, foot platform 551 b is free to pivot about pin cor~nection 716 enabling the user to freely rotate platform 551 b to any number of ylcrc~d acute angular positions relative to a line or axis extending from one end 537b of ~e~plocating member 532b to its other end 534b. Notwithstanding the angular orientation s~lect~l1 by the user during the cycling motion, platform 551 b will continue to maintain a closed substantially elliptical path 602 as shown in Fig. 7.
~s rlic~lcse~l above, such elliptical movement provides for ~lcfe~ed anatomical response ~nilulluzing damage and injury to the ankles and knees.
Referring now to Fig. 8c, another alternate embodiment of foot contact member 550 as shown in Fig. 7 is depicted. Reciprocating member 532c is generally the same nonlin~r configuration as that of reciprocating member 532b of Fig. 8B except that it indudes apertures 718 adapted to accommodate pin connections 720 which fixedly WO 97/07860 1 1 PcT/u~ 3199 secure platform support member 722. As in the case of Fig. 8b, platform 551c is pivotaUy connected at connection 724 enabling the user to pivot platform 551 c to the desired acute angular orientation. The embodiment shown in Fig. 8c is distinguishable from the embodiment shown in Fig. 8b in that the user may disengage pins 720 andreposition member 722 rclaL~,e to member 532c by i~ ing pins 720 in other ap~ s 718. This changes the profile of closed elliptical path 602. As platform 551 c is moved rearwardly towards roller 536c, elliptical path 602 is fl~ttlonerl thereby deemphasizing vertical movement of each platform 551c. This may be a ~r~ d anatomical pattcrn for some users.
Referring now to Fig. 8d, a further im~ro~,clnent is shown over the embo-lim~nt of Fig.8b. Once again, reciprocating member 532d is nonlinear and includes a platform support member 726 which, through pivotal connection 728, supports one end of platform 551d. The other end of platform 551d is supported by scissor members 732/734. Each scissor member 732 and 734 is pivotally connected to one another at connection 736. The other end of member 732 is pivotaUy connected at connection 730 to foot platform 551d. The other end of member 734 is pivotally connected at connection 738 to the end 534d of re~i~rocating member 532d ~r~,xi.~te roller 536d.
A tensioning member 800 is pivotally attached at one end to member 726 through pin connection 802. The distal portion of member 800 is supported through a bushing arrangement 804 p~ te pin connection 736. A spring 808 is placed over the portion of member 800 distal pin connection 802. A nut and washer arrangement 810 is then secured through a threaded portion on the distal end of member 800 to co~ r~ss spring 808. In this manner, the operation of the embodiment shown in Fig. 8d is generally similar to the embodiment shown in Fig. 8b except that the pivotal motion of platform 551 d is partially restrained by the colllpr~ re nature of spring 808. That is, during ~~ cy~ling motion d~wllw~l pressure through the heel of the user against the rear portion of platform 551d ~ c~nt pin connection 730 serves to compress or close the scissor members 732/734 thereby com~r~sillg spring 808. In this manner, free pivotal movement of platform 551d about pin connection 728 is somewhat restrained eliminating the possibility of any erratic pivotal motion of platform 551 d.
Referring now to the embodiment shown in Fig. 8e, the arrangement therein is substantially identical to the embodiment shown in Fig. 8d except for the substitution of a shoc~damper 820 in place of spring 808 of Fig. 8d. In this manner, shock/damper 820 serves to retard cc~ les~i~,c and tensile forces. Thus, as the user exerts a heel load on platform 551e ~ te pivot connection 740 the com~rer,~ive force serves to CU~ 5 or close scissor members 742 and 744. However, shock/damper 820 inhibits abrupt compr~,si~,e loading of scissor members 742/744 by placing a tensile load on member 830. Similarly, if the user places an ~x es,ive toe load forward of pin connection 750 which serves to raise the heel portion of platform 55 le, shock/damper 820 serves to inhibit a rapid extension of scissor members 742/744 by placing a compressive load on member 830. In this manner, pivotal motion of platfonn 551e about pin connection 750 is controlled. While pivotal motion is still ~lmi~Led enabling the user to adjust the angle of platform 551 e to the ~r~c~d acute angular orientation, the overall movement of both foot plaLlc,lllls remains on the generally elliptical path 602 of Fig.7.
Finally, r~c~lillg to Fig. 8f, an alternate embodiment is shown of a nonlinear reciprocating member 536f which is similar in configuration to the embodiment shown in Fig. 8b. The primary ~c~Lion with respect to the embodiment of Fig. 8b is theinclusion of a flange 860 attached to the bo~Lc~ of platform 551f having apertures 870.
Platfonm support member 872 includes an aperture through which a pin 875 passes providing pivotal movement of platform 551f thlo~,h one aperture 870 relative tomember 872. The embodiment shown in Fig. 8f is a modification over the embodiment shown in Fig. 8b in that it permits the user to select more precisely the pivot point of platform 551f relative to its longitudinal position on lc i~l~,cating member 532f. This may have certain benefits by increasing or decreasing the amount of calf musde involved in the exercise since pivotal orientation will be varied requiring lower leg muscle control to maintain the proper acute angular orientation as the foot platform 551f movesthrough substantially elliptical path 602.
Obviously, modifications and alterations to the preferred embodiment disclosed herein will be a~al~t to those skilled in the art in view of this disclosure. ~uw~vel, it is intended that all such variations and modifications fall within the spirit and scope of this ill~,cll~ion as ~l~ime~l
