Description
- This application is a divisional application of U.S. patent application Ser. No. ______ (Attorney File No. SN-US035146) filed on Nov. 14, 2003. The entire disclosure of U.S. patent application Ser. No. ______ (Attorney File No. SN-US035146) is hereby incorporated herein by reference.
- 1. Field of the Invention
- This invention generally relates to a bicycle pedal. More specifically, the present invention relates clipless or step-in bicycle pedal, which has at least one pedal body cover to prevent the cleat from scratching the pedal body.
- 2. Background Information
- Bicycling is becoming an increasingly more popular form of recreation as well as a means of transportation. Moreover, bicycling has become a very popular competitive sport for both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle as well as the frame of the bicycle. One component that has been extensively redesigned is the bicycle pedal.
- In recent years, bicycle pedals have been designed for specific purposes such as for pleasure, off road biking, road racing, etc. One particular type of bicycle pedal, which is gaining more popularity, is the step-in or clipless pedal, which releasably engages a cleat secured to the sole of a cyclist's shoe. The clipless pedal has a pedal spindle that can be mounted on the crank of a bicycle, a pedal body that is rotatably supported on this pedal spindle, and a cleat engagement mechanism. In an off road bicycle pedal a cleat engagement mechanism is formed on both sides of the pedal body for engaging a cleat. A road-racing pedal, on the other hand, typically only has a cleat engagement mechanism on one side of the pedal body. In either case, in these types of bicycle pedals, the rider steps onto the pedal and the cleat engagement mechanism automatically grips on to the cleat secured to the bottom of the cyclist's shoe.
- With this type of step-in or clipless pedal, the shoe and the pedal are in a state of constant engagement when the cleat is engaged in the cleat clamping members, so the pedaling force can be transmitted efficiently to the pedals. As a result, step-in or clipless pedals are widely employed on racing bicycles used in road racing and mountain bike racing.
- When attaching the cyclist's shoe to the step-in or clipless pedal via the cleat, the cyclist moves the shoe obliquely downwardly and forwardly relative to the pedal body such that the front end of the cleat engages a front hook or clamping member of the pedal body. Once the front end of the cleat is engaged with the front hook of the pedal body, the cyclist places the rear end of the cleat in contact with a guide portion of the rear hook or clamping member of the pedal body. In this position, the cyclist presses the shoe downwardly against the pedal to cause the rear hook or clamping member to initially pivot rearwardly against the force of a spring to move the rear hook or clamping member to a cleat releasing position. The rear end of the cleat then enters a position opposite a back face of the rear hook or clamping member. Then, the rear hook or clamping member returns under the force of a biasing member or spring so that the rear hook or clamping member engages the rear end of the cleat. This engagement fixes the cyclist's shoe to the pedal via the cleat.
- When releasing the shoe from the pedal, the cyclist will typically turn the shoe about an axis perpendicular or approximately perpendicular to the tread of the pedal, using the front end of the cleat as a pivoting point. As a result of this pivoting action, the rear hook or clamping member is pivoted rearwardly against the force of the spring to a cleat releasing position to release the shoe. It is important that the cleat does not inadvertently release the pedal during normal pedaling. Some of these prior step-in or clipless pedals can inadvertently release the cleat during normal pedaling if the spring force on the rear clamping member is set too low. However, if the spring force on the rear clamping member is set too high, the cleat may not release from the pedal properly. This could result in the rider's shoe not properly releasing from the pedal at the desired application of force because the rider's shoe either releases too easily from the pedal or does not release at the proper time. Thus, some of these step-in or clipless pedals and the cleats for these pedals are designed with adjustment mechanisms to change the release force required for the rider to disengage the cleat from the pedal. However, these adjustment mechanisms increase the overall cost of the pedals. In particular, these adjustment mechanisms can be complicated and expensive to manufacture and assemble.
- Moreover, during normal riding conditions and when releasing the shoe from the pedal, the rider will typically turn the shoe about an axis perpendicular or approximately perpendicular to the tread of the pedal which often results in the pedal body being scratched by the cleat. Thus, many attempts have been made to add a protective cover to the pedal body. However, these protective covers increase the overall cost of the pedals.
- In view of the above, there exists a need for an improved bicycle pedal assembly that takes into account at least come of the above mentioned problems in the prior art. This invention addresses this need in the prior art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
- One object of the present invention is to provide a bicycle pedal that is configured and arranged with at least one pedal body cover to prevent the cleat from scratching the pedal body.
- Another object of the present invention is to provide a step-in bicycle pedal assembly that is relatively lightweight and malfunction free.
- Yet another object of the present invention is to provide a step-in bicycle pedal assembly that is relatively simple and inexpensive to manufacture.
- In accordance with one aspect of the present invention, the foregoing objects can basically be achieved by providing a bicycle pedal that comprises a pedal shaft, a pedal body, a front clamping member, a rear clamping member and a first pedal body cover. The pedal shaft has a center rotational axis. The pedal body is rotatably coupled to the pedal shaft about the center rotational axis of the pedal shaft. The pedal body has a first end and a second end with a center plane extending between the first and second ends and passing through the center rotational axis of the pedal shaft and a first cleat engaging side of the pedal body being defined between the first and second ends on a first side of the center plane of the pedal body. The front clamping member is coupled to the first end of the pedal body by a front fastener. The front clamping member has a front cleat engagement surface facing towards the center plane of the pedal body. The rear clamping member is coupled to the second end of the pedal body by a rear fastener. The rear clamping member has a rear cleat engagement surface facing towards the center plane of the pedal body. The first pedal body cover is coupled to the pedal body by at least a first one of the front and rear fasteners and is arranged to cover a first area of the pedal body located along a center section of the first cleat engaging side of the pedal body. At least one of the front and rear clamping members is pivotally coupled to the pedal body between a cleat engaged position to a cleat released position by the first one of the front and rear fasteners.
- In accordance with one aspect of the present invention, the foregoing objects can basically be achieved by providing a pedal body cover for a bicycle pedal that comprises at least a protective body portion and a first attachment leg. The protective body portion is configured and dimensioned to overlie an area located along a center section of a pedal body of the bicycle pedal. The first attachment leg extends from the protective body portion. The first attachment leg is configured and dimensioned relative to the protective body portion to be retained to the pedal body of the bicycle pedal by a first pivot pin that pivotally couples a first clamping member of the bicycle pedal.

It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
- Referring initially to
FIG. 1 , abicycle 10 is illustrated that is equipped with aleft bicycle pedal 12 a and a right bicycle pedal 12 b in accordance with a first embodiment of the present invention. Thebicycle pedals 12 a and 12 b are fixedly coupled to a pair of bicycle crank arms 14 a and 14 b of abicycle 10 for rotation therewith. - As seen in
FIGS. 2-5 , the left andright bicycle pedals 12 a and 12 b selectively engage a pair of cleats A and B. Thus, the left andright bicycle pedals 12 a and 12 b and the cleats A and B that are form a bicycle pedal assembly in accordance with a first embodiment of the present invention. The first and second bicycle shoe cleats A and B are preferably fixedly coupled to a pair of bicycle shoes in a conventional manner (e.g., a pair of screws) to releasably couple the cyclist's foot to thebicycle pedals 12 a and 12 b. - In the illustrated embodiment, the
bicycle pedals 12 a and 12 b are especially designed for use with off-road bicycles as opposed to use with a road bicycle. However, it will be apparent to those skilled in the art from this disclosure that the features of thebicycle pedals 12 a and 12 b can be used in the construction of a road type of bicycle pedal if needed and/or desired. In other words, it will be apparent that thebicycle pedals 12 a and 12 b can be designed such that the first and second bicycle shoe cleats A and B can only be coupled to one side of thebicycle pedals 12 a and 12 b. - Specifically, the cleats A and B are engaged with the
bicycle pedals 12 a and 12 b by pressing the cleats A and B into thepedals 12 a and 12 b with a forward and downward motion. This releasably locks the cleats A and B to thepedals 12 a and 12 b. The cleats A and B can be released from thepedals 12 a and 12 b by twisting the heel of the shoe to the outside ofpedals 12 a and 12 b as discussed below in more detail. - The first and second bicycle shoe cleats A and B are configured and arranged to selectively cooperate with the
bicycle pedals 12 a and 12 b such that two different release forces can be attained using a single pair of cleats A and B. In particular, as illustrated inFIGS. 2 and 3 , the first and second bicycle shoe cleats A and B are configured and arranged to release upon application of a first predetermined amount of outward twisting force F1 when the first bicycle shoe cleat A is engaged with theleft bicycle pedal 12 a and the second bicycle shoe cleat B is engaged with the right bicycle pedal 12 b. - However, as illustrated in
FIGS. 4 and 5 , the first and second bicycle shoe cleats A and B are configured and arranged to release upon application of a second predetermined amount of outward twisting force F2 that is higher than the first predetermined amount of outward twisting force F1 when the first bicycle shoe cleat A is engaged with the right bicycle pedal 12 b and the second bicycle shoe cleat B is engaged with theleft bicycle pedal 12 a. - As seen in
FIGS. 2-5 , theleft bicycle pedal 12 a is a mirror image of the right bicycle pedal 12 b. It will be apparent to those skilled in the art from this disclosure that the description of theleft bicycle pedal 12 a also applies to the right bicycle pedal 12 b and vice a versa. Thus, the same reference numerals will be used to describe both the left andright pedals 12 a and 12 b. Moreover, theleft bicycle pedal 12 a will not be discussed or illustrated in further detail herein for the sake of brevity. - The left and the
right bicycle pedals 12 a and 12 b basically each includes a pedal shaft orspindle 21, apedal body 22, a pair of front (first) clampingmembers 23 pivotally coupled to thepedal body 22 by a pair of pivot pins 24, a pair of rear (second) clampingmembers 25, a pair ofspring holders 26 and a pair of biasingmembers 28. Also, thepedal body 22 preferably includes two pairs of pedal body covers 30 that overlie a center upper portion of thepedal body 22 to protect thepedal body 22 from scratches. Thepedals 12 a and 12 b have an overall length X and an overall height Y as seen inFIG. 8 . - As shown in
FIG. 1 , thepedal spindles 21 are fastened to the crank arms 14 a and 14 b of thebicycle 10, with thepedal bodies 22 being rotatably coupled to thepedal spindle 21 for supporting the rider's feet. Specifically, the cleats A and B are fixedly attached to the bicycle shoes, which in turn are releasably attached to thepedal bodies 22 via one of the pairs of the front andrear clamping members - The
pedal spindle 21 is a multi-step spindle having numerous stepped portions. Thepedal spindle 21 has afirst end 31 with threads formed thereon for threadedly coupling bicycle pedal to the crank arm 14 a or 14 b in a conventional manner. The other end of thepedal spindle 21 rotatably supports thepedal body 22 in a conventional manner. Thepedal body 22 can freely rotate about the center rotational axis R of thepedal spindle 21. Since thepedal spindle 21 is relatively conventional and its specific construction is not critical to the present invention, the construction of thepedal spindle 21 will not be discussed in detail herein. - As shown in
FIGS. 12-14 , thepedal body 22 is an H-shaped member (seeFIG. 12 ) that basically includes acenter tubular portion 41, an innerside mounting portion 42 and an outerside mounting portion 43. Thepedal body 22 is a rigid member that is preferably made as a one-piece, unitary member from a lightweight material such as an aluminum alloy. As best seen inFIGS. 9-11 , thepedal body 22 is rotatably coupled to thepedal spindle 21 for rotation about a center rotational axis R of thepedal spindle 21. - In particular, the
center tubular portion 41 has a stepped bore 44 (seeFIG. 14 ) for receiving thepedal spindle 21 for rotation about the center rotational axis R. Theside mounting portions members side mounting portion 42 extends in a forward and backward direction from an inner end of thecenter tubular portion 41. Theside mounting portions pedal body 22. The cover receiving recesses 45 are configured and arranged to receive the pedal body covers 30, respectively. - The inner
side mounting portion 42 has a pair of threaded holes or bores 46 that threadedly receive the pivot pins 24 therein. The outerside mounting portion 43 extends in a forward and backward direction from an outer end of thecenter tubular portion 41. The outerside mounting portion 43 has a pair ofblind bores 47 that receives the free ends of the pivot pins 24 therein. The unthreaded blind bores 47 are axially aligned with the threaded bores 46 for receiving the outer end of the pivot pins 24. Thebores pedal body 22 can be formed. In other words, the threaded bores 46 aids in providing an attractive appearance, since the heads of the pivot pins 24 are not visible from the outside of thepedal body 22. One of thefront clamping members 23 is pivotally mounted at each end of thepedal body 22 by one of the pivot pins 24. Likewise, one of therear clamping members 25 is pivotally mounted at each end of thepedal body 22 by one of the pivot pins 24. - The
pedal body 22 has a center longitudinal line CL extending between the front and the rear ends as seen inFIG. 10 . The center longitudinal line CL of thepedal body 22 extends substantially perpendicular to the center rotational axis R of thepedal spindle 21 and bisects the clampingmembers pedal body 22 also has a center plane P1 extending between the first and second ends of thepedal body 22 with the center plane P1 passing through the center rotational axis R of thepedal spindle 21 and the centers ofbores FIGS. 11 and 13 . The center plane P1 divides thepedal body 22 into first and second cleat engagement sides. A cleat receiving area is formed on each side ofpedal body 22 for receiving and supporting the cleats A and B thereon. More specifically, the cleat receiving area is defined the area extending longitudinally between the clampingmembers pedal body 22. Thus, the cleats A and B are designed to releasably couple a sole of a shoe to thebicycle pedals 12 a and 12 b by a pair of the front andrear clamping members pedal body 22 relative to the center plane P1. - Each biasing
member 28 is preferably formed by a pair of torsion springs. The torsion springs of the biasingmembers 28 have their coiledportions 50 mounted on the pivot pins 24, with oneend 51 of each spring engaging a part of one of thefront clamping members 23, and theother end 52 of each spring engaging a part of one of therear clamping members 25. The biasingmembers 28 normally urge clampingmembers members 28 normally maintain the clampingmembers members 28 of the clampingmembers pedals 12 a and 12 b. - Referring back to
FIGS. 2-5 , the clampingmembers members pedal body 22 by the pivot pins 24. As seen inFIG. 10 , the clampingmembers pedal body 22, with their two free ends being swingably supported by the pivot pins 24 that pass between the inner and outerside mounting portions pedal body 22. - Referring now to
FIGS. 19-23 , each of thefront clamping members 23 includes a connectingportion 60 with a pair oflegs 61 extending downwardly from connectingportion 60 for coupling thefront clamping member 23 to thepedal body 22 via one of the pivot pins 24. More specifically, each of thelegs 61 of thefront clamping members 23 has a mountinghole 63 formed therein for receiving one of the pivot pins 24. Accordingly, each of thefront clamping members 23 is pivotally mounted about itsrespective pivot pin 24 for movement between a cleat clamping or engaging position and a cleat releasing position. - Each of the connecting
portions 60 of thefront clamping members 23 has a front cleat engagement portion orsurface 64 and a front cleat stop portion orsurface 65. The frontcleat engagement surface 64 faces generally towards the center plane P1 of thepedal body 22, while the frontcleat stop surface 65 is spaced forwardly from the center rotational axis R of thepedal spindle 21 by a first predetermined distance d1 measured parallel to the frontcleat engagement surface 64 as seen inFIGS. 8 and 11 . The frontcleat engagement surface 64 of each front clampingmember 23 is configured and arranged to engage a front portion of the cleats A and B to limit movement of the cleats A an B away from the pedal body. The frontcleat stop surface 65 of each front clampingmember 23 is configured and arranged to engage a front portion of the cleats A and B to limit forward movement of the cleats A and B. The frontcleat engagement surface 64 is a flat planar surface. The frontcleat stop surface 65 is a flat planar surface that extends substantially perpendicular to the frontcleat engagement surface 64. - Each of the
legs 61 of thefront clamping members 23 also has a first stop portion orflange 66 and a second stop portion orflange 67. Thefirst stop portions 66 of each of thefront clamping members 23 are configured and arranged to engage thepedal body 22 to limit rotational movement of the front clampingmember 23 in a first rotational direction about the respective one of the pivot pins 24. Thesecond stop portions 67 of each of thefront clamping members 23 are configured and arranged to engage thepedal body 22 to limit rotational movement of the front clampingmember 23 in a second rotational direction about the respective one of the pivot pins 24. More specifically, thefirst stop portions 66 of each of thefront clamping members 23 are normally biased against thepedal body 22 by the respective one of the biasingmembers 28. Thesecond stop portions 67 of each of thefront clamping members 23 are normally spaced frompedal body 22 by a predetermined amount. Thus, as seen inFIG. 6 , thefront clamping members 23 can pivot about the pivot pins 24 against the urging forces of the biasingmembers 28 such that thefront clamping members 23 can pivot in a generally forward direction by a first predetermined rotational distance or amount θ1. Preferably, thefront clamping members 23 can pivot in a generally forward direction by approximately three degrees to about five degrees as measured about the center axis of the respective one of the pivot pins 24. - Referring now to
FIGS. 24-28 , each of therear clamping members 25 includes a connectingportion 70 with a pair oflegs 71 extending downwardly from connectingportion 70 for coupling therear clamping member 25 to thepedal body 22 via one of the pivot pins 24. More specifically, each of thelegs 71 of therear clamping members 25 has a mountinghole 73 formed therein for receiving one of the pivot pins 24. Accordingly, each of therear clamping members 25 is pivotally mounted about itsrespective pivot pin 24 for movement between a cleat clamping or engaging position and a cleat releasing position. - Each of the connecting
portions 70 of therear clamping members 25 has a rear cleat engagement portion orsurface 74 and a rear cleat stop portion orsurface 75. The rearcleat engagement surface 74 faces generally towards the center plane P1 of thepedal body 22. The rearcleat stop surface 75 is spaced rearwardly from the center rotational axis R of thepedal spindle 21 by a second predetermined distance d2 measured parallel to the rearcleat engagement surface 74 as seen inFIGS. 8 and 11 . The rearcleat engagement surface 74 of each rear clampingmember 25 is configured and arranged to engage a rear portion of the cleats A and B to limit movement of the cleats A an B away from the pedal body. The rearcleat stop surface 75 of each rear clampingmember 25 is configured and arranged to engage a rear portion of the cleats A and B to limit rearward movement of the cleats A and B. The rearcleat engagement surface 75 is a flat planar surface. The rearcleat stop surface 75 is a flat planar surface that extends substantially perpendicular to the rearcleat engagement surface 74. - Each of the
legs 71 of therear clamping members 25 also has astop surface 76 that is configured and arranged to engage thepedal body 22 to limit rotational movement of therear clamping member 25 in a first rotational direction about the respective one of the pivot pins 24, i.e., hold therear clamping member 25 in rest or cleat engaging position. More specifically, the stop surfaces 76 of each of therear clamping members 25 are normally biased against thepedal body 22 by the respective one of the biasingmembers 28. Thus, therear clamping members 25 can pivot about the pivot pins 24 against the urging forces of the biasingmembers 28 such that therear clamping members 25 can pivot in a generally rearward direction by a predetermined rotational distance or amount θ2, as seen inFIG. 6 . Preferably, the predetermined rotational distance θ2 is about thirteen degrees, when the pedal and cleat are arranged to require the first predetermined outward twisting force F1 and about fourteen degrees, when the pedal and cleat are arranged to require the second predetermined outward twisting force F2. Preferably, therear clamping members 25 can pivot in a generally rearward direction by at least fourteen degrees as measured about the center axis of the respective one of the pivot pins 24. - As seen in
FIG. 11 , first and second cleat engagement surfaces 64 and 74 preferably lie in substantially the same plane, which forms an acute angle with the center plane P1. Thus, the first and second cleat engagement surfaces 64 and 74 hold the cleat A or B from moving vertically from thepedal body 22. Preferably, the firstcleat engagement surface 64 is spaced from the pivot axis of thepivot pin 24 by a predetermined distance L1, while the secondcleat engagement surface 74 is spaced from the pivot axis of thepivot pin 24 by a predetermined distance L2 that is larger than the predetermined distance L1. The first and second cleat stop surfaces 65 and 75 hold the cleat A or B from moving in a front to rearward direction of thepedal body 22. Preferably, the first and second cleat stop surfaces 65 and 75 are spaced apart by a predetermined distance S1. Moreover, the secondcleat stop surface 75 is spaced (offset) from the center rotational axis R of thepedal spindle 21 by the predetermined distance d2, while the firstcleat stop surface 65 is spaced (offset) from the center rotational axis R of thepedal spindle 21 by the predetermined distance d1 that is larger than the predetermined distance d2. The dimensions d1 and d2 are measured along a plane that extends perpendicular to the first and second cleat stop surfaces 65 and 75. Since dimension d1 is greater than the dimension d2, the step-in torque is approximately 17% greater than if the dimensions d1 and d2 were equal. - As seen in
FIGS. 24-28 , therear clamping members 25 are provided with a generallyhorizontal portion 77 and a generallyvertical portion 78. Theportions real body 22 to horizontal position for engagement as seen inFIGS. 39 and 40 . As seen inFIG. 11 , the generallyhorizontal portion 77 extends in a substantially rearward direction past the end of thepedal body 22 by a predetermined distance S2 that is at least substantially equal to or greater than the predetermined distance S1. The generallyhorizontal portion 77 of therear clamping members 25 is provided with anopening 79 for receiving thespring holder 26 to couple the second ends 52 of the torsion springs that form the biasingmember 28 to therear clamping member 25. - Referring now to
FIGS. 17 and 18 , each of the pedal body covers 30 basically includes aprotective body portion 90, a first attachment leg 91 and asecond attachment leg 92. The first andsecond attachment legs 91 and 92 have attachment holes 93 and 94, respectively, which are configured and dimensioned for receiving the pivot pins 24 therethrough. Thus, the four pedal body covers 30 are fixedly coupled to thepedal body 22 by the pivot pins 24. In other words, the first andsecond attachment legs 91 and 92 of the pedal body covers 30 are configured and dimensioned relative to theprotective body portions 90 to be retained to thepedal body 22 by the pivot pins 24 which constitute front and rear fasteners. - Each of the pedal body covers 30 is a rigid member that is preferably made as a one-piece, unitary member from a material that is harder than the material of the
pedal body 22 such as stainless steel. Thepedal body 22 has four of the pedal body covers 30 with two of the pedal body covers 30 mounted on each side of thepedal body 22 in the cover receiving recesses 45. In particular, the pedal body covers 30 are located at the ends of thecenter tubular portion 41 in the area where the cleat A or B will rub against thepedal body 22 if the pedal body covers 30 were removed. In other words, theprotective body portions 90 of the first and second pedal body covers 30 are configured and dimensioned to overlie the first and second areas located along the center section of thepedal body 22. - Moreover, the
protective body portions 90 of a first pair of the pedal body covers 30 that are located on a first side of the center plane P1 each includes a section that lies in a first plane, while the first pair of the first andsecond attachment legs 91 and 92 of the first pair of the pedal body covers 30 have sections that includes the first andsecond holes 93 and 94 that lie in second and third planes that are substantially perpendicular to the first plane of the first pair of theprotective body portions 90 of the pedal body covers 30. Likewise, the second pair of the pedal body covers 30 that are located on a second side of the center plane P1 each includes a section that lies in a fourth plane that is parallel to the first plane of the first pair of the pedal body covers 30 that are located on a first side of the center plane P1. The second pair of the first andsecond attachment legs 91 and 92 of the second pair of the pedal body covers 30 have sections that includes the first andsecond holes 93 and 94 that lie in fifth and sixth planes that are substantially perpendicular to the fourth plane of the second pair of theprotective body portions 90 of the pedal body covers 30. - Referring now to
FIGS. 29-38 , the cleats A and B are basically mirror images of each other. It will be apparent to those skilled in the art from this disclosure that the descriptions of the portions of the cleat A (FIGS. 29-33 ) also to applies to the corresponding portions of the cleat B (FIGS. 34-38 ) and vice a versa. Thus, the same reference numerals will be used to describe both the portions of the cleat A and the corresponding portions of the cleat B for the sake of brevity. - Basically, each of the cleats A and B includes an
attachment portion 100, a first or front coupling portion ormember 101 extending from one end of theattachment portion 100 and a second or rear coupling portion ormember 102 extending from the other end of theattachment portion 100. The front coupling portion ormember 101 has a pair of lateral front corner abutments CF1 and CF2, while the rear coupling portion ormember 102 has a pair of lateral rear corner abutments CR1 and CR2. The front corner abutments CF1 and CF2 selectively contact thefront clamping member 23 when the cleat is pivoted about its pivot axis P of the cleat A or B, while the rear corner abutments CR1 and CR2 selectively contact therear clamping member 25 when the cleat is pivoted about its pivot axis P of the cleat A or B. The pivot axis P is located at the intersection of a first line that extends between the front and rear corner abutments CF1 and CR1 and a second line that extends between the front and rear corner abutments CF2 and CR2 as seen inFIGS. 33 and 38 . The pivot axis P also lies on a center line CL of the cleat A or B. As seen inFIGS. 32 and 37 , the front and rear corner abutments CF1 and CR1 are spaced laterally from the center line CL of the cleat A or B by a first lateral distance DL1, while the front and rear corner abutments CF2 and CR2 are spaced laterally from the center line CL of the cleat A or B by a second lateral distance DL2 that is larger than the first lateral distance DL1. This arrangement at least partially results in the low outward twisting force F1 and the high outward twisting force F2 for release the cleat A or B depending on which of the cleats A and B are used with which of thepedals 12 a and 12 b. - The
attachment portion 100 has an uppersole side 103 facing in a first direction for engaging the sole of the shoe and a lower pedal side facing 104 in a second direction which is substantially opposite to the first direction. Preferably theattachment portion 100 and thecoupling portions - The
attachment portion 100 has a pair of hole or slot 105 for receiving one or more fasteners for fixedly coupling to the sole of the cyclist's shoe in a relatively conventional manner. The interconnection of the cleat A to the sole is relatively well known in the art, and thus, this interconnection will not be discussed or illustrated in detail herein. - The
front coupling portion 101 is designed to engage thefront clamping member 23. Thefront coupling portion 101 has a nose portion orflange 106 with a first orfront coupling surface 106 a, a centerfront stop surface 107 and a pair of lateral front stop surfaces 108. Thefront coupling surface 106 a faces towards the sole of the shoe, while the front stop surfaces 107 and 108 extend substantially perpendicular to thefront coupling surface 106 a. The centerfront stop surface 107 is designed to engage thefront stop surface 65 of the front clampingmember 23 to prevent forward movement of the cleats relative to thepedal body 22. - The center front stop surfaces 107 is arranged to extend perpendicular to a center line CL of the cleat A or B that divides the
front coupling surface 106 a into two equal side portions. The lateral front stop surfaces 108 are angled relative to the center front stop surfaces 107 so that they are inclined rearwardly as they extend outwardly from the center front stop surfaces 107. Preferably, the lateral front stop surfaces 108 are angled about five degrees relative to the center front stop surfaces 107. The lateral front stop surfaces 108 are designed to engage thefront stop surface 65 of the front clampingmember 23 when the cleat is pivoted about its pivot axis P of the cleat A or B. The lateral front stop surfaces 108 form the front lateral corner abutments CF1 and CF2 that are spaced from the center line CL of the cleat A or B. The front lateral corner abutment CF1 is spaced a shorter distance from the center line CL of the cleat A or B than the front lateral corner abutment CR2 from the center line CL of the cleat A or B. Thus, the rear lateral corner abutment CR1 forms a low force rear corner abutment, while the rear lateral corner abutment CR2 forms a high force rear corner abutment. - The second or
rear coupling portion 102 extends from the second end of theattachment portion 100. Therear coupling portion 102 is designed to engage therear clamping member 25. Therear coupling portion 102 has a nose portion orrear flange 109 and a centerrear stop surface 110 and a pair of lateral rear stop surfaces 111. The nose portion orrear flange 109 includes a second orrear coupling surface 109 a and a rear edge 109 b extending perpendicularly relative to therear coupling surface 109 a. The rear edge 109 b includes corners CRR1 and CRR2 that define the release points of therear flange 109. In other words, when the cleat A or B is pivoted about its pivot axis P of the cleat A or B, therear flange 109 will be twisted outwardly from underneath therear clamping member 25. The cleat A or B will release from therear clamping member 25 when one of the corners CRR1 and CRR2 of therear flange 109 aligns with therear stop surface 75 of therear clamping member 25. In other words, when one of the corners CRR1 and CRR2 of therear flange 109 can be seen from above, the rear flange of the cleat A or B releases from therear stop surface 75 of therear clamping member 25. The corner CRR1 is located on the same side of the center line CL as the rear lateral corner abutment CR1, while the corner CRR2 is located on the same side of the center line CL as the rear lateral corner abutment CR2. Therear flange 109 is shifted from the center line CL towards the rear lateral corner abutment CR2 by an OFFSET distance to control the release angle. Thus, the corners CRR1 and CRR2 of therear flange 109 are symmetrically arranged about the OFFSET axis that is parallel to the center line CL. Preferably, in the preferred embodiment, the OFFSET distance is about 0.65 mm from the center line CL of the cleat A or B towards the rear lateral corner abutment CR2. Preferably, thisOFFSET distance is dimensioned together with the corners CRR1 and CRR2 of therear flange 109 and the rear lateral corner abutments CR 1 and CR 2 such that the release angle (e.g., 15°) is substantially identical for each of the cleats A and B whether used with theleft pedal 12 a or the right pedal 12 b. - The
rear coupling surface 109 a faces towards the sole of the shoe, while the rear stop surfaces 110 and 111 extend substantially perpendicular to therear coupling surface 110. The rear stop surfaces 110 and 111 are designed to engage thestop surface 75 of therear clamping member 25 to prevent rearward movement of the cleat A or B relative to thepedal body 22. Preferably, the coupling surfaces 106 a and 109 a are formed so as to lie in substantially the same plane. - The lateral rear stop surfaces 111 are angled relative to the center
rear stop surface 110 so that they are inclined forwardly as they extend outwardly from the centerrear stop surface 110. Preferably, the lateral rear stop surfaces 111 are angled about five degrees relative to the centerrear stop surface 110. The lateral rear stop surfaces 111 are designed to engage therear stop surface 75 of therear clamping member 25 when the cleat A or B is pivoted about its pivot axis P of the cleat A or B. - The rear stop surfaces 110 and 111 are symmetrically arranged about an
OFFSET that is spaced by 0.65 mm to one side of the cleat A or B from the center line CL of the cleat A or B. The lateral rear stop surfaces 111 form the rear lateral corner abutments CR1 and CR2 that are spaced from the center line CL of the cleat A or B. The rear lateral corner abutments CR1 and CR2 formeffective lever arms lever arm 112 is shorter than thelever arm 113. The lateral corner abutment CR1 is spaced a shorter distance from the center line CL of the cleat A or B than the lateral corner abutment CR2 from the center line CL of the cleat A or B. Thus, when the lateral corner abutment CR1 engages therear stop surface 75 of therear clamping member 25 upon the application of an outward twisting force, the cleat A or B easier to pivot to the release position than the lateral corner abutment CR2 engages therear stop surface 75 of therear clamping member 25. - One preferred assembly operation of the
bicycle pedals 12 a and 12 b will now be discussed. Thebicycle pedals 12 a and 12 b are assembled by initially installing the front andrear clamping members bicycle pedal body 22 by the pivot pins 24. This is done by positioning the front andrear clamping members side mounting portions second attachment legs 91 and 92 of the four pedal body covers 30 have their attachment holes 93 and 94 arranged for receiving the pivot pins 24 therethrough. Now, the biasingmembers 28 are held in place between the front andrear clamping members pedal body 22 such that the front andrear clamping members members 28 and the pedal body covers 30 are mounted on the pivot pins 24. Thus, the pedal body covers 30 are fixedly coupled to thepedal body 22 by the pivot pins 24, while the front andrear clamping members pedal body 22 by the pivot pins 24. In this state the biasingmembers 28 are not in their fully preloaded state. Thus, the springs of the biasingmembers 28 are now wound about the pivot pins 24 and thespring holders 26 are insert into openings of therear clamping members 25 to properly preload the biasingmembers 28, which urge the front andrear clamping members members 28 to be initially installed in unload or load loaded state for easy assembly. In other words, the front andrear clamping members members 28 can be installed on thebicycle pedal body 22 without having to preloaded the biasingmembers 28 under high tension. - Operation of the bicycle pedal 12 b will now be briefly described with reference mainly to
FIGS. 39-40 . Due to the unique construction of thebicycle pedals 12 a and 12 b, the rider can easily rotate the pedal 12 a or 12 b from a non-horizontal position as seen inFIGS. 39 and 40 to a substantially horizontal position as seenFIGS. 41 and 42 . When a bicycle shoe is to be attached to one of thebicycle pedal 12 a, the rider can rotate the pedal 12 a from the non-horizontal position shown inFIG. 39 to a substantially horizontal position as seenFIGS. 41 and 42 , by rotating thebicycle pedal 12 a in a counter clockwise direction. Because the front andrear clamping members rear clamping members 25 are offset from the axis R, the rider can easily rotate the pedal 12 a. Moreover, when the pedal 12 a is in the non-horizontal position shown inFIG. 40 , the rider can easily rotate the pedal 12 a in either direction. - Once the pedal 12 a is in a substantially horizontal position as seen
FIGS. 41 and 42 , the rider moves the tip of the shoe forward towards one of thefront clamping members 23 so that the tip of the cleat A or B is inserted underneath one of thefront clamping members 23. Once the tip of the cleats A and B has been inserted underneath one of thefront clamping members 23, a downwardly directed force is applied by the shoe, such that the shoe is pushed down toward thebicycle pedal body 22. When the shoe is pressed down further from this state shown inFIGS. 41 and 42 , the rear end of the cleat A or B rotates one of therear clamping members 25 backward against the biasing force of one of the biasingmembers 28. Simultaneously, the front end of the cleat A or B rotates the front clampingmember 25 forward against the biasing force of the other one of the biasingmembers 28. The cleat A or B then slides between the front and rear clampingmember member member members 28 back to their original positions. As a result, the cleat A or B is engaged between the front and rear clampingmember 23 and 25 (seeFIG. 2 ). - When the shoe is to be removed from the
bicycle pedal 12 a or 12 b, the heel portion of the shoe is lightly twisted to the outside about the pivot axis P. This twisting motion will cause the front and rear clampingmember members 28, and the engagement of the rear end of the cleat A or B will be released instantly. Depending on which of the cleats A and B are used with which pedal will determine the release force F1 or F2 that is necessary to rotate the cleats A and B to their release positions. - As used herein, the following directional terms “forward, rearward, above, downward, vertical, horizontal, below and transverse” as well as any other similar directional terms refer to those directions of a bicycle equipped with a pedal of the present invention and when the pedal is horizontally oriented relative to the ground. Accordingly, these terms, as utilized to describe the present invention should be interpreted relative to a bicycle equipped with a pedal of the present invention.
- The terms of degree such as “substantially”, “about” and “approximately” as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. These terms should be construed as including a deviation of at least ±5-10% of the modified term if this deviation would not negate the meaning of the word it modifies.
- While only selected embodiments have been chosen to illustrate the present invention, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. Furthermore, the foregoing descriptions of the embodiments according to the present invention are provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
