DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

(32) Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

(33) Referring initially to FIG. 1, a shoe positioning plate 10 is illustrated in accordance with one embodiment. The shoe positioning plate 10 is attached to a left bicycle shoe 12 by a pair of fasteners 14 (e.g., screws). As seen in FIG. 2, the shoe positioning plate 10 has been replaced with a cleat 16, which is attached to the bicycle shoe 12 by the fasteners 14. While a right bicycle shoe is not shown, it will be apparent to those skilled in the art from this disclosure that the shoe positioning plate 10 and the cleat 16 can be selectively mounted to the sole of the right bicycle in the same manner as described herein with respect to the left bicycle shoe 12.

(34) In the illustrated embodiment, by way of example, the shoe positioning plate 10 and the cleat 16 are designed to be used with Shimano Pedaling Dynamics (SPD) line of clipless or step-in pedals. However, it will be apparent to those skilled in the art from this disclosure that the shoe positioning plate 10 can be adapted to be used in other types of clipless or step-in pedals. Thus, the shoe positioning plate of the present invention is not limited to Shimano Pedaling Dynamics (SPD) line of clipless or step-in pedals.

(35) As seen in FIG. 3, the bicycle shoe 12 includes an upper part 18 and a shoe sole 20, with the shoe sole 20 having a recessed area 22 with two elongated attachment openings 24. A cleat nut plate 26 disposed inside the bicycle shoe 12 for receiving the fasteners 14 to attach either the shoe positioning plate 10 or the cleat 16 to the shoe sole 20. The cleat nut plate 26 has six threaded holes for receiving the fasteners 14 to selectively attach the cleat 16 in three different positions.

(36) As seen in FIGS. 5 to 8, a clipless or step-in bicycle pedal 30 is illustrated for use with the shoe positioning plate 10 and the cleat 16. In the illustrated embodiment, by way of example, the bicycle pedal 30 is illustrated as a Shimano Pedaling Dynamics (SPD) clipless or step-in pedal. The bicycle pedal 30 is especially designed for use with off-road bicycles as opposed to use with a road bicycle. Of course, the bicycle pedal 30 can be a road type of bicycle pedal if needed and/or desired. Also the present invention can be applied to bicycle pedals other than Shimano Pedaling Dynamics (SPD) clipless or step-in pedals. Since step-in pedals such as the bicycle pedal 30 are well known, the bicycle pedal 30 will only be briefly described and/or illustrated herein.

(37) When the shoe positioning plate 10 mates with the bicycle pedal 30, the shoe positioning plate 10 is not fixed to the bicycle pedal 30. This shoe positioning plate 10 is only inserted the bicycle pedal 30. The shoe positioning plate 10 can be especially useful to beginners who may be initially afraid to have their shoes fixed on bicycle pedals when they use the ordinary cleats. Therefore, someone, who has not used a step-in pedal system before, can easily step into a step-in bicycle pedal and experience the clip on pedal condition (relative position of a pedal and a shoe) without the shoe actually be fixed to the step-in bicycle pedal by using the shoe positioning plate 10. Since the shoe positioning plate 10 is not fixed to the step-in bicycle pedal, the shoe positioning plate 10 is easily removed from the bicycle pedal 30 with little resistance. Moreover, in bicycle shops or bicycle shows, when a customer tries to use a step-in bicycle pedal using the shoe positioning plates 10 on the shoes, the bicycle pedals is not injured.

(38) As seen in FIGS. 5 and 6, the bicycle pedal 30 mainly includes a pedal spindle or axle 32, a pedal body 34, and a cleat engagement mechanism comprising a pair of front cleat engagement members 36 and a pair of rear cleat engagement members 38. The pedal spindle 32 is adapted to be threadedly coupled to a crank arm (not shown). The pedal body 34 is rotatably supported on the pedal spindle 32 for supporting a rider's foot. Each of the front cleat engagement members 36 is rigidly fixed to the pedal body 34 by a plurality (three) of attachment bolts (not shown), Each of the rear cleat engagement members 38 is pivotally coupled to the pedal body 34 by a pivot pin 40, with a biasing member 42 being mounted on each of the pivot pins 40 to bias the rear cleat engagement members 38, respectively, to a rest (cleat engagement) position.

(39) As best seen in FIGS. 5 and 6, the front cleat engagement members 36 are each provided with a front stop surface 36a and a front pedal body facing surface 36b. The front stop surface 36a limits forward movement of the shoe positioning plate 10 (FIG. 5) or the cleat 16 (FIG. 6) with respect to the pedal body 34 depending on whether the shoe positioning plate 10 or the cleat 16 is attached to the shoe sole 20. The pedal body facing surface 36b faces toward the pedal body 34 and engages with the cleat 16 when the cleat 16 is engaged with the cleat engagement mechanism. The rear cleat engagement members 38 are each provided with a rear stop surface 38a and a rear pedal body facing surface 38b. The rear stop surface 38a limits rearward movement of the shoe positioning plate 10 (FIG. 5) or the cleat 16 (FIG. 6) with respect to the pedal body 34 depending on whether the shoe positioning plate 10 or the cleat 16 is attached to the shoe sole 20. The rear pedal body facing surface 38b faces toward the pedal body 34 and engages with the cleat 16 when the cleat 16 is engaged with the cleat engagement mechanism.

(40) Turning now to FIGS. 9 to 14, the shoe positioning plate 10 has a shoe facing side surface 50, a sole surface 52 and a shoe positioning member 53. The shoe facing side surface 50 has an overall concave profile, and the sole surface 52 has an overall convex profile. The sole surface 52 is configured to be a part of the shoe sole 20 when the shoe facing side surface 50 is attached the shoe sole 20. The sole surface 52 is disposed on an opposite side of the shoe positioning plate 10 from the shoe facing side surface 52 and extends in an elongated (longitudinal) direction of the shoe 12 when the shoe positioning plate 10 is attached the shoe sole 20. In the illustrated embodiment, the shoe positioning plate 10 is a one-piece, unitary member, which is constructed from a suitable material such as a hard plastic material (e.g. synthetic resin) or any one of the materials are used in bicycle shoe soles. It is possible to make the shoe positioning plate 10 out of two or more separate parts, but typically this will increase production costs and/or decrease the ease of installation of the shoe positioning plate 10.

(41) In this embodiment, the outer periphery of the shoe positioning plate 10 substantially matches the outer periphery of the recessed area 22 such that the shoe positioning plate 10 preferably fills at least a majority of the recessed area 22 and more preferably over eighty percent of the recessed area 22. The sole surface 52 is disposed so as to match the bottom surface of the shoe sole 20 when the shoe facing side surface 50 is attached the shoe sole 20. In other words, the sole surface 52 of the shoe positioning plate 10 contacts a flat surface when a ball area 20a (containing the recessed area 22) of the bicycle shoe 12 is positioned against the flat surface area. More preferably, the contour of the sole surface 52 matches the contour of the ball area 20a of the shoe sole 20 as view in a side elevational view of the bicycle shoe 12. In this way, the shoe positioning plate 10 and the surrounding bottom surface of the ball area 20a contact the ground together when the wearer is walking.

(42) In this embodiment, the shoe positioning member 53 includes a forward abutment 54 and a rearward abutment 56, with the rearward abutment 56 facing in an opposite direction from the forward abutment 54. The tips (i.e., the farthest spaced apart points) of the forward and rearward abutments 54 and 56 are spaced apart by a prescribed cleat body distance D. In the illustrated embodiment, the forward and rearward abutments 54 and 56 are convex faces that cooperate with the front and rear stop surfaces 36a and 38a, respectively. In the illustrated embodiment, the forward and rearward abutments 54 and 56 mate with the front and rear stop surfaces 36a and 38a, respectively, such that the shoe positioning plate 10 can be inserted in between the front and rear stop surfaces 36a and 38a from a direction generally perpendicular to the bottom of the shoe sole 20 of the bicycle shoe 12 without causing the corresponding rear cleat engagement member 38 to be pivoted. In this way, the shoe positioning plate 10 can be removed from the bicycle pedal 30 without twisting the shoe positioning plate 10, which is needed to disengage the cleat 16 from the bicycle pedal 30 in practical terms. Of course, the prescribed cleat body distance D of the shoe positioning plate 10 can be preset with respect to the bicycle pedal 30 such that is moved slightly for a snug fit. Also, due to manufacturing tolerances and/or wear, the prescribed cleat body distance D of the shoe positioning plate 10 can be preset with respect to the bicycle pedal 30 such that a small amount of play (e.g., 2.0 millimeters) exists between the forward and rearward abutments 54 and 56 of the shoe positioning plate 10 and the front and rear stop surfaces 36a and 38a of the front and rear cleat engagement members 36 and 38, respectively. Thus, when the term “substantially” modifies the term “prescribed cleat body distance”, the term “substantially” means±2.0 millimeters.

(43) In the case of Shimano Pedaling Dynamics (SPD) clipless or step-in pedal systems, the prescribed cleat body distance D would be equal to 33.3 millimeters±2.0 millimeters. Of course, when the present invention is applied to other step-in pedal systems, the prescribed cleat body distance D would be different. Generically speaking, as used herein, the prescribed cleat body distance D of a shoe positioning plate constructed in accordance with the present invention refers to a distance corresponding to the length of a cleat body of a cleat for the clipless or step-in pedal system in which the shoe positioning plate is to be used. The cleat body refers to a fore-to-aft portion of the cleat with respect to the longitudinal direction of a bicycle pedal body, in which the fore-to-aft portion of the cleat is retrained from movement in the fore-to-aft portion with respect to the longitudinal direction of the bicycle pedal body. A cleat body (i.e., the fore-to-aft portion) of a cleat will be discussed below using an SPD cleat (e.g., the cleat 16) as an example to explain the meaning of the cleat body (i.e., the fore-to-aft portion) of the cleat.

(44) The shoe positioning plate 10 is also provided with two fastener openings 58 in the shoe positioning member 53, with the fastener openings 58 extending between the shoe facing side surface 50 and the sole surface 52. In securing the shoe positioning plate 10 to the shoe sole 20, the fasteners 14 are inserted from the sole surface 52 of the shoe positioning plate 10 into the fastener openings 58 of the shoe positioning plate 10. The fasteners 14 pass through the fastener openings 58 of the shoe positioning plate 10 and then pass through the attachment openings 24 of the shoe sole 20, where they are then threaded into threaded holes in the cleat nut plate 26.

(45) The shoe facing side surface 50 is further provided with two elongated protrusions 60. In this embodiment, the fastener openings 58 are located between the forward and rearward abutments 54 and 56 with respect to the longitudinal direction of the shoe positioning plate 10. The fastener openings 58 are arranged such that one of the fastener openings 58 passes through each of the elongated protrusions 60. The elongated protrusions 60 can have lengths that corresponds the lengths of the attachment openings 24 of the shoe sole 20 if needed and/or desired.

(46) In this embodiment, the sole surface 52 has a forward recess 64 and a rearward recess 66. The forward recess 64 defines a forward face of the forward abutment 54. The rearward recess 66 defines a rearward face of the rearward abutment 56. A front guide 68 is partially defined by the forward recess 64. A rear face of the front guide 68 is inclined in a direction away from the shoe facing side surface 50 as the front guide 68 extends away from the forward abutment 54. A rear wall 70 is defined by the rearward recess 66. The rear wall 70 is disposed across the rearward recess from the rearward abutment 56 without any obstructions disposed in the rearward recess 66 between the rearward abutment 56 and the rear wall 70. In the illustrated embodiment, a gap exists between the rear wall 70 and the corresponding rear cleat engagement member 38. However, in certain step-in pedal systems, the rear wall 70 can contact a rear cleat engagement member to give a tighter mating contact between the shoe positioning plate 10 and the corresponding rear cleat engagement member.

(47) In the shoe positioning plate 10 of the illustrated embodiment, a cutout 72 divides the rear wall 70 into two lateral parts. The rearward abutment 56 and the cutout 72 are disposed across the rearward recess 66 from each other such that the cutout 72 is aligned with the rearward abutment 56.

(48) Referring now to FIGS. 13 to 18, the bicycle shoe cleat 16 is a conventional cleat that is used with Shimano Pedaling Dynamics (SPD) line of clipless or step-in pedals. The bicycle shoe cleat 16 includes a cleat body portion 80, a front retaining portion 82 and a rear retaining portion 84. The bicycle shoe cleat 16 has an attachment opening or slot 86 for receiving fasteners 14 to attach the bicycle shoe cleat 16 to the bicycle shoe 12 via the cleat nut plate 26 in a conventional manner. The bicycle shoe cleat 16 has an upper sole side facing in a first direction for engaging the shoe sole 20 of the shoe 12 and a lower pedal side facing in a second direction which is substantially opposite to the first direction. In the illustrated embodiment, the cleat body portion 80, the front retaining portion 82 and the rear retaining portion 84 are integrally formed together as a one-piece, unitary member, which is constructed from a suitable rigid material.

(49) The cleat body portion 80 has a front curved stop surface 88 and a rear curved stop surface 90. The curved stop surface 88 is a convex surface that contacts the front stop surface 36a of the front cleat engagement member 36 to limits forward movement of the cleat 16 (FIG. 6) with respect to the pedal body 34. The curved stop surface 90 is a convex surface that contacts the rear stop surface 38a of the rear cleat engagement member 38 to limits rearward movement of the cleat 16 (FIG. 6) with respect to the pedal body 34.

(50) The front retaining portion 82 has a nose portion with a first or front coupling surface 92. The coupling surface 92 faces towards the shoe sole 20 of the shoe 12, The front curved stop surface 88 is perpendicularly arranged with respect to the coupling surface 92. The coupling surface 92 engages the front pedal body facing surface 36b of the front cleat engagement member 36 to prevent the bicycle shoe cleat 16 from being pulled straight out of the bicycle pedal 30.

(51) The rear retaining portion 84 has a nose portion with a second or rear coupling surface 94. The coupling surface 94 faces towards the shoe sole 20 of the shoe 12. The rear curved stop surface 90 is perpendicularly arranged with respect to the coupling surface 94. The coupling surface 94 engages the rear pedal body facing surface 38b of the rear cleat engagement member 38 to prevent the bicycle shoe cleat 16 from being pulled straight out of the bicycle pedal 30, The rear retaining portion 84 also has a ramp surface 96. The ramp surface 96 is designed to rotate the rear cleat engagement member 38 rearward from its normal cleat engaging position to its cleat releasing position as the cleat 16 is moved downward against the rear cleat engagement member 38.

(52) In coupling the cleat 16 to the bicycle pedal 30, the rider steps onto pedal body 34 which in turn causes the rear cleat engagement member 38 to automatically grip onto the cleat 16 for securing to the shoe sole 20 of the bicycle shoe 12. More specifically, when attaching the bicycle shoe 12 to the step-in pedal 30 through the cleat 16, the rider moves the shoe 12 obliquely downwardly and forwardly relative to the pedal body 34 such that the front end of the cleat 16 engages the front cleat engagement member 36. Once the front end of cleat 16 is engaged with the front cleat engagement member 36, the rider places the rear end of cleat 16 in contact with the rear cleat engagement member 38. In this position, the rider presses the shoe 12 downwardly against the bicycle pedal 30 to cause the rear cleat engagement member 38 to initially pivot rearward against the force of the biasing member 42 to a cleat releasing position. Then, the rear cleat engagement member 38 returns under the force of the biasing member 42 so that the rear cleat engagement member 38 engages the rear end of the cleat 16. This engagement fixes the bicycle shoe 12 to the pedal 30 via the cleat 16. For all practical matters, the cleat 16 cannot be pulled straight out of the bicycle pedal 30 due to the large force of the biasing member 42. Rather to release the shoe 12 from the bicycle pedal 30, the rider will typically need to turn or twist the shoe 12 about an axis perpendicular or approximately perpendicular to the coupling surfaces 92 and 94 of the cleat 16. As a result of this pivoting or twisting action, the rear cleat engagement member 38 is pivoted against the force of the biasing member 42 to a cleat releasing position to release the shoe 12 from bicycle pedal 30.

(53) As seen in FIGS. 21 and 22, the shoe positioning plate 10 (FIGS. 9 to 14) can be install on a competition bicycle shoe 112 if needed and/or desired. The bicycle shoe 112 includes an upper part 118 and a shoe sole 120, with the shoe sole 120 having a recessed area 122 with two elongated attachment openings 124. Of course, the shape of the shoe positioning plate 10 can be adjusted to the dimensions of the particular shoe. In other words, although the shoe positioning plate 10 is illustrated as being install directly on the competition bicycle shoe 112 without any modifications, it will be apparent to those skilled in the art that the dimensions of the shoe positioning plate 10 can be adjusted to better match the competition bicycle shoe 112 if needed and/or desired.

(54) FIGS. 23 to 30 illustrate various shoe positioning plates 110, 210, 310 and 410 in accordance with other embodiment. These shoe positioning plates 110, 210, 310 and 410 can be used with the bicycle shoes 12 and 112 or any other bicycle shoe for step-in or clipless pedals as needed and/or desired. In each of the shoe positioning plates 110, 210, 310 and 410, a shoe positioning member is provided that mates with the bicycle pedal 30.

(55) In particular, as seen in FIGS. 23 and 24, the shoe positioning plate 110 has a shoe facing side surface 150, a sole surface 152 and a shoe positioning member 153. In the illustrated embodiment, the shoe positioning plate 110 is a one-piece, unitary member, which is constructed from a suitable material such as a hard plastic material or any one of the materials are used in bicycle shoe soles. The shoe positioning member 153 includes a forward abutment 154 and a rearward abutment 156, with the rearward abutment 156 facing in an opposite direction from the forward abutment 154. The tips (i.e., the farthest spaced apart points) of the forward and rearward abutments 154 and 156 are spaced apart by the prescribed cleat body distance for the particular bicycle pedal. The shoe positioning plate 110 is also provided with two fastener openings 158 in the shoe positioning member 153, with the fastener openings 158 extending between the shoe facing side surface 150 and the sole surface 152.

(56) In particular, as seen in FIGS. 25 and 26, the shoe positioning plate 210 has a shoe facing side surface 250, a sole surface 252 and a shoe positioning member 253. In the illustrated embodiment, the shoe positioning plate 210 is a one-piece, unitary member, which is constructed from a suitable material such as a hard plastic material or any one of the materials are used in bicycle shoe soles. The shoe positioning member 253 includes a forward abutment 254 and a rearward abutment 256, with the rearward abutment 256 facing in an opposite direction from the forward abutment 254. In the illustrated embodiment, a recess divides the shoe positioning member 253 into two halves. The tips (i.e., the farthest spaced apart points) of the forward and rearward abutments 254 and 256 are spaced apart by the prescribed cleat body distance for the particular bicycle pedal. The shoe positioning plate 210 is also provided with two fastener openings 258 disposed between the two halves of the shoe positioning member 253, with the fastener openings 258 extending between the shoe facing side surface 250 and the sole surface 252.

(57) In particular, as seen in FIGS. 27 and 28, the shoe positioning plate 310 has a shoe facing side surface 350, a sole surface 352 and a shoe positioning member 353. In the illustrated embodiment, the shoe positioning plate 310 is a one-piece, unitary member, which is constructed from a suitable material such as a hard plastic material or any one of the materials are used in bicycle shoe soles. The shoe positioning member 353 includes a forward abutment 354 and a rearward abutment 356, with the rearward abutment 356 facing in an opposite direction from the forward abutment 354. In the illustrated embodiment, a recess divides the shoe positioning member 353 into two halves, with each half having a cantilevered part. The tips (i.e., the farthest spaced apart points) of the forward and rearward abutments 354 and 356 are spaced apart by the prescribed cleat body distance for the particular bicycle pedal. The shoe positioning plate 310 is also provided with two fastener openings 358 disposed between the two halves of the shoe positioning member 353, with the fastener openings 358 extending between the shoe facing side surface 350 and the sole surface 352.

(58) In particular, as seen in FIGS. 29 and 30, the shoe positioning plate 410 has a shoe facing side surface 450, a sole surface 452 and a shoe positioning member 453. In the illustrated embodiment, the shoe positioning plate 410 is a one-piece, unitary member, which is constructed from a suitable material such as a hard plastic material or any one of the materials are used in bicycle shoe soles. The shoe positioning member 453 includes a forward abutment 454 and a rearward abutment 456, with the rearward abutment 456 facing in an opposite direction from the forward abutment 454. The tips (i.e., the farthest spaced apart points) of the forward and rearward abutments 454 and 456 are spaced apart by the prescribed cleat body distance for the particular bicycle pedal. The shoe positioning plate 410 is also provided with two fastener openings 458 disposed between the two halves of the shoe positioning member 453, with the fastener openings 458 extending between the shoe facing side surface 450 and the sole surface 452. In the illustrated embodiment the outer periphery of the shoe positioning plate 410 is much smaller than the outer periphery of the recessed area 22 in the lengthwise direction. The overall width of the shoe positioning plate 410 is the same size as the shoe positioning plates 10, 110, 210 and 310, but smaller in the lengthwise direction. Thus, the shoe positioning plate 410 does not fill as much of the recessed area 22 as the shoe positioning plates 10, 110, 210 and 310, when the shoe positioning plate 410 is installed on the bicycle shoe 12 or 112.
