(ctms-62') y `The present invent-ion `relates to a hospitalbed and more particularly t-o that type `of hospital bed wherein the mattress supporting structure is formed of various sections articulated to one another. r
More particularly, the invention is concerned basically with a mechanism for reclining a seat rest and a thigh rest of such a mattress supporting structureeither simultaneously or independently of one another, in conjunction with` separate actuating means for adjusting the` angular position of the head rest and" that of the leg rest of the same mattress supporting structure.
A main object of the invention resides in the provisionof a hospital bed of the abovementioned type particularly suitable for obtaining Trendelenburg `or shock position, that is a position of the` body for medical examination United States Patent() or operation wherein the patient is supine on a tableV inclined `at from 109 to 20fa from the horizontal inf a perfectly straight line; with the r and the knees and legs uppermost.` y
It is also animportant object of the invention to provide such a hospital, bed wherein the thigh rest which is articulated to the seat rest may be actuated :by an elevating mechanism independently of the said seat rest and wherein both the Isaid seat rest and thigh rest may be raised into inclined position` simultaneously and in in-line relationship by the same elevating mechanism.
It is also within the scope of the `invention to provide a hosiptal bed wherein separate and individual elevating mechanisms are used for lifting thedhead section, articulated to the seat section, and the legsection, articulated to the thigh section. i v i The above mentioned objects maybe attained witha reclining hospital bed made `according to the invention which comprises: a horizontal `bedl -frame adapted to support the mattress supporting structure above the floor, this structure including a seat rest with supporting 1means for holding it in spaced relationship with the bed frame inV one particular position of the bed; an underfrarne secured to the supportingmeans below the seat rest and articulated at the forward end thereof to the bed frame;
` the mattress supporting structure ,also including a thigh rest articulated, at one end,.to the `rearward end of the seat rest and provided with elevating means interconnecting it with the bed fra-me, rearwardly o the articulated end of the thigh rest and `finally locking means for locking the underframe to the thigh rest when the latter is in alignmentwithithe feet rest ,whereby in locked condition,4 the elevating means will rotate the seat rest and the thigh rest in unison. about the articulated. means of the underframe, and, when unlocked, will rotate the thigh rest aboutits Iarticulated end.` Y
In a preferred form of the invention, the elevating `means comprises a pair of operating leverson at least one side of the bed frame, the levers being articulated together at one Vof their ends and being articulated, at the other ends, to the thigh rest and to rotatable shaft mounted transversely of the bed frame, respectively; actuating means being provided for causingrotation of the transverse shaft thus articulating the levers to raise or lower the thigh rest. Y
Again, in accordance with a preferredernbodiment of the invention, the locking means comprises: an L- shaped arm pivoted intermediate the ends thereof on the underframe and having a light and a heavy branch head laying lowerrnost rice `whereby the resultingunbalance tends tocause rotation in a 'predetermined direction; a locking` pin on thefthigh rest; a hook, formed in the light branch, adapted to receive the lpin when the thigh 'rest and the seat rest are in alignment; and means for releasing the hookfrom the pin and maintaining it out of engagement therewith.
Further objects and otherl advantages of the invention will become vapparent as the following description proceeds of a preferred embodiment of the invention and in relation with the appended drawings wherein:
FIG. l is a view in Velevation showingV the mattress supporting structure in Trendelenburg" or shock position;
FIG. 2 is a side elevation view similar to that ofFlG. 1 but showing the various sections ofthe bed supporting structure in out of line position;A Y Y FIG. 3 is an enlarged partial side elevation. View intended to particularly illustrate the articulating mean-s' of the underframe and thehead rest; FIG. 4 is also an enlarged side elevation partial view of the locking means for joining together the underframe andthe leg rest; Y
As illustrated =in FIG. 1,'the hospital bed made accord-g ing to the invention generally comprises a'horizontal bed frame 1 supported, as is` known, forwardly and rearwardly by upward head and foot framesjvg, 3', respectively;fjprovided with suitable casters Sfor moving about the iloor.
Over horizontal bed frame 1`- is mounted a mattress supporting frame 7 formed"v of head rest 9, seat rest 11, thigh rest 13 and leg rest 15; Supporting frame 7 also includes the usual side railings 17 for protecting tifI patient, particularly in transit.
As seen particularly in FIGS. 1 and 2, seat restl 11` is secured on either side thereof, to the top portion of sup` porti-ng brackets or legs 19. Legs 19 are provided with suitable means, not shown, `for retaining seat restll in spaced parallel relationship with horizontal bed frame 1 in the particular postionshown in FIG. 2.
Rearwardly of the seatrest 11 is alocking means (to be described in more detail later) adapted to` join together the underrframe 27 and the thigh rest 13. Also, an ele- 1 vating means (again to be more fully described later) is provided which interconnects the horizontal bed frame and the thigh rest =13. Thus,when the locking meanslocks together'the underframe 27 andthe thigh rest 13, the situation is that illustrated in FIG. l whereby when the elevating means is operated, both the seat rest and the thigh restare raised' in unison. Similarly, a linkage mechanism joins the articulated axle between thighI and leg rests4 13 and 15 to bed frame 1 and is providedwith suitable meansfor holding the said legl rest into inclined position as shown in FIGS. l and 2. l
The elevating means for' thigh rest 13 (as well as for seat rest 11 through underfrarne 27 as Will'be seen later) comprises an angular lever 3345"and` an arm on at least one side of said frame 11. The lever 334`5 iormsa xed angle between two arms 33' and 45. Thelever andthe arm 33 are articulated together at one of, their ends by means of an articulated pin or the like and the arm 33 is articulated at its other ends 37 to thigh rest 13. The apex of lever 3345 is mounted onto a rotatable shaft 41 (see FIG. 4) transversely of bed frame- 1. An actuating means is provided for causing rotation of the lever 3345 whereby causing articulation of the arm 33 to thus raise or lower thigh rest 13. As said previously, actuation of this actuating means in the ease where thigh rest 13 is locked with underfrarne 27 when it is in alignment with seat rest 11 will cause the two rests to move in unison, as illustrated in FIG. 1.
The actuating means for elevating thigh rest 13 comprises an elevating means 43 generally composed of a threaded rod receivable into a cylinder having a threaded bore. The cylinder, as will be understood, is rotatable by means of a handle 47 to thereby cause the threaded rod to move in or out of the threaded cylinder thus forcing oscillation of the lever 33-45 and articulation of arm 33 with consequent raising or lowering of thigh rest 13.
In conjunction with this elevating means, is a locking means for joining together the thigh rest 13 and the seat rest 11 when the two are in alignment as shown in FIGS. 1 and 4.
The locking means comprises an L-shaped arm 49 pivoted at 50 intermediate the ends thereof on underframe 27 and having a light branch 51 as well as a heavy branch 53 whereby resulting in an unbalance which tends to cause rotation of the lever or arm in a predetermined direction. The locking means also includes a locking pin 55 on thigh rest 13 and more particularly on a strut or the like stiiiening member 59 provided underneath the said thigh rest 13; this pin 55 being adapted to be received in a hook 57 formed at the end of the light branch 51. Means is provided for releasing the hook from the pin and maintaining it out of engagement therewith, this releasing means comprising: a link 61 mounted on transverse shaft 41 for rotation thereon, the said link is biased in a vertical position on account of the weight or pulling means at the lower end of said link; a lug 63 secured to the free end of heavy branch 53 of L-shaped arm 49, this lug being engageable in a notch 65 formed in link 61. Nut 69 projects laterally of link 61 at one extreme end thereof. Finally, a push rod or operating rod 67 is secured to the other end of the said link. As shown in FIG. 2, push rod 67 is available adjacent handle 47 of the elevating mechamsm.
The weight of rod 67 tends to keep link 61 in the vertical position particularly shown in dotted lines in FIG. 4. A nut `69 iixed to the link 61 normally maintains the L- shaped arm 49 in the tilted position shown in dotted lines in FIG. 4.
It will be understood from perusal of FIG. 4, that under the heavier weight of branch 53 of L-shaped lever 49, when rests 11 and 13 are in alignment and in the position shown in FIG. 4, hook 57 has a tendency to move over locking pin 55 t0 lock thigh rest 13 to underframe 27 when the nut 69 is out of the way of the arm 49, that is, when the rod 67 has been pulled and the link 61 is tilted as shown in full `lines in FIG. 4. If it is intended to lock the thigh rest 13 to the underframe 27, then push rod 67 is actuated forwardly (to the right) causing an anti-clockwise rotation of link 61 and engagement of lug 63 in notch 65. In this position, the hook 57 cannot come apart from pin 55 because the pin 63 is locked in notch 65. The bed is now raised in one plane as shown in FIG. 1. The link 61 returns to its vertical position as shown in FIG. 2 by the weight of rod 67. A spring may also be used to pull the rod 67 in the direction of the foot rest. In order to unlock thigh rest 13 and the underframe 27, the handle 47 is actuated to return the bed from the inclined position (FIG. l) to a horizontal position. Eventually, nut 69 reaches and rides along the lower edge of the heavy branch 53 as indicated in broken lines in FIG. 4 to remove lug 5S out of engagement with hook 57.
Turning back to FIGS. 1 and 2, an articulated linking means formed of Va lower lever 71 and a rack bar 73 interconnected together and to bed frame 1 and articulation axle 25, respectively, is provided for retaining the leg rest 15 into inclined position, whenever desired. The articulated means also includes a bracing bar 75 pivoted at one end to leg rest 15 and having a cross bar (not shown) at the other end thereof selectively engageable into the notches 77 of rack bar 73. This way it is possible to give a positive inclination to and support to leg rest 15 as illus-- trated in FIGS. 1 and 2.
Finally, means is provided for articulating the head rest 9, which means is more particularly illustrated in FIG. 3 and is shown to include at least one angular lever 79 on the side of bed frame 1, pivotally mounted on axle 29, at the apex thereof, on bracket 31 fixed to the bed frame l1. The means also includes a link 81 articulated at one end to the head rest 9 and at the other end to one end of angular lever 79 while a pushing rod S3 may be used for causing oscillation of angular lever 79 to thereby vary the inclination of head rest 9 in relation to horizontal frame 1.
