Bicycle lock plate, bicycle pedal, bicycle pedal assembly and bicycle pedal system

Abstract

A bicycle pedal includes a pedal shaft, a pedal body, a first cleat securing member, a second cleat securing member, a first biasing member, and a first resistance member. The pedal body is rotatable relative to the pedal shaft. The first cleat securing member is pivotable between a first cleat retaining position and a first cleat non-retaining position. The second cleat securing member is disposed to the pedal body and spaced apart from the first cleat securing member to form a cleat receiving area therebetween. The first biasing member applies a first biasing force to the first cleat securing member to bias the first cleat securing member toward the first cleat retaining position. The first resistance member applies a first resistance to a cleat in addition to the first biasing force during a cleat disengagement operation from the first cleat securing member and the second cleat securing member.

Description

Technical Field

[0001] This disclosure generally relates to bicycle cleats, bicycle pedals, bicycle pedal assemblies, and bicycle pedal systems. More specifically, this disclosure relates to a bicycle pedal configured to interchangeably and releasably secure one or more bicycle cleats. Background Technology

[0002] Bicycle pedals are designed for specific purposes, such as comfort, recreational riding, cross-country riding, and road racing. One increasingly popular type of bicycle pedal is the step-in or clipless pedal. Conventional step-in or clipless pedals are releasably connected to cleats fixed to the sole of the rider's shoe. Thus, the bottom of the rider's shoe is secured to the pedal, transferring pedaling force from the rider to the bicycle pedal. In other words, with clipless pedals, the shoe and pedal are in a constant engagement state when the cleats are engaged in the cleat clamping mechanism, allowing pedaling force to be efficiently transferred to the pedals. A typical clipless bicycle pedal includes a pedal axle that can be attached to the bicycle crank, a main pedal body rotatably supported on the pedal axle, and a cleat retaining mechanism. For this type of conventional bicycle pedal, cleat disengagement is typically performed by twisting the shoe while it is engaged with the pedal, causing the heel to move outward. Summary of the Invention

[0003] In general, this disclosure relates to various features of bicycle cleats, bicycle pedals, bicycle pedal assemblies, and bicycle pedal systems. It has been found that the engagement state between the bicycle cleat and the bicycle pedal can vary depending on the wear of the shoe sole. Therefore, the disengagement force that causes the bicycle cleat attached to the shoe to disengage from the bicycle pedal in a direction perpendicular to the pedaling surface varies depending on the engagement state between the bicycle cleat and the bicycle pedal.

[0004] In view of the state of the prior art, and according to a first aspect of this disclosure, a bicycle clip is provided, the bicycle clip substantially comprising a shoe attachment portion and a first clip protrusion. The shoe attachment portion has a shoe side surface and a pedal side surface. The first clip protrusion has a first surface portion with a first bevel and a first additional surface portion with a first additional bevel. The first bevel is different from the first additional bevel. The first surface portion is configured to be closer to the pedal side surface than the first additional surface portion.

[0005] According to the bicycle cleat of the first aspect, the bicycle cleat can be reliably held to the bicycle pedal regardless of the engagement state between the bicycle cleat and the bicycle pedal.

[0006] According to a second aspect of this disclosure, a bicycle pedal is configured to interchangeably and releasably secure each of a dual-position cleat, a first cleat, and a second cleat. The dual-position cleat includes a shoe attachment having a shoe-side surface and a pedal-side surface, and a first dual-position cleat protrusion including a first surface portion having a first bevel and a first additional surface portion having a first additional bevel. The first bevel is different from the first additional bevel. The first surface portion is positioned closer to the pedal-side surface than the first additional surface portion. The first cleat includes a first shoe attachment having a first shoe-side surface and a first pedal-side surface, and a first cleat protrusion having a first surface portion with a first bevel, the first surface portion being spaced apart from the first shoe-side surface by a first distance. The second cleat includes a second shoe attachment having a second shoe-side surface and a second pedal-side surface, and a third cleat protrusion having a third surface portion with a third bevel, the third surface portion being spaced apart from the second shoe-side surface by a second distance. The second distance is different from the first distance. The bicycle pedal includes a pedal axle, a pedal body, and a first cleat securing member. The pedal axle has a rotational central axis. The pedal body is rotatably disposed about the rotational central axis. A first cleat fixing member is pivotally mounted to the pedal body about a first pivot axis. The first cleat fixing member has a first cleat engagement surface. The dual-position cleat is at least partially configured such that, in a first engagement state where the first cleat engagement surface engages with a first surface portion of the dual-position cleat while the bicycle pedal is fixed to the dual-position cleat, compared to a second engagement state where the first cleat engagement surface engages with a first additional surface portion of the dual-position cleat while the bicycle pedal is fixed to the dual-position cleat, it is further from the pedal body. In a third engagement state where the bicycle pedal is fixed to the first cleat, the first cleat engagement surface contacts a first surface portion of a first cleat protrusion of the first cleat. In a fourth engagement state where the bicycle pedal is fixed to the second cleat, the first cleat engagement surface contacts a third surface portion of a third cleat protrusion of the second cleat. The first cleat is at least partially configured such that, in the third engagement state, it is further from the pedal body than the second cleat in the fourth engagement state.

[0007] According to the second aspect of the bicycle pedal, the bicycle pedal can interchangeably and releasably fix each of the dual-position cleat, the first cleat, and the second cleat, so as to achieve a proper engagement state when the sole of the shoe wears more, and to allow cleats of different structures to engage properly.

[0008] According to a third aspect of this disclosure, a bicycle pedal assembly is provided, generally including a cleat and a bicycle pedal. The cleat includes a shoe attachment having a shoe-side surface and a pedal-side surface, and a first cleat protrusion. The first cleat protrusion includes a first surface portion having a first bevel and a first additional surface portion having a first additional bevel. The first bevel is different from the first additional bevel. The first surface portion is configured to be closer to the pedal-side surface than the first additional surface portion. The bicycle pedal is configured to releasably secure the cleat. The bicycle pedal includes a pedal axle, a pedal body, and a first cleat securing member. The pedal axle has a rotational central axis. The pedal body is rotatably disposed about the rotational central axis. The first cleat securing member is pivotally disposed to the pedal body about a first pivot axis. The first cleat securing member includes contacting a first cleat engagement surface of the first cleat protrusion in a cleat-secured state on the bicycle pedal. The cleat is at least partially disposed further from the pedal body in a first engagement state where the first cleat engagement surface engages with the first surface portion, compared to a second engagement state where the first cleat engagement surface engages with the first additional surface portion.

[0009] According to the bicycle pedal assembly of the third aspect, the bicycle pedal can reliably fix the locking plate, thereby achieving a proper engagement state as the sole of the shoe wears more.

[0010] According to a fourth aspect of this disclosure, the bicycle pedal assembly of the third aspect is configured such that a first slope of a first surface portion is inclined in a first tilting direction, the first surface portion is inclined away from a first additional surface portion in the first tilting direction, and approaches the pedal side surface as the first surface portion extends outward relative to the shoe attachment toward the outer edge of the cleat. A first additional slope of the first additional surface portion is inclined in a first additional tilting direction, the first additional surface portion is inclined away from the shoe side surface in the first additional tilting direction, and approaches the first surface portion as the first surface portion extends outward relative to the shoe attachment toward the outer edge of the cleat.

[0011] According to the bicycle pedal assembly described in the fourth aspect, the bicycle pedal is reliably fixed to the locking plate in both the first and second engaged states.

[0012] According to a fifth aspect of this disclosure, a bicycle pedal assembly according to a third or fourth aspect is configured such that the cleat further includes a second cleat protrusion, the second cleat protrusion including a second surface portion having a second bevel and a third additional surface portion having a second additional bevel. The second bevel is different from the second additional bevel. The second surface portion is configured to be closer to the pedal side surface than the second additional surface portion. The bicycle pedal also includes a second cleat fixing member pivotally disposed to the pedal body about a second pivot axis. The second cleat fixing member includes contacting a second cleat engagement surface of the second cleat protrusion in a bicycle pedal cleat-fixed state. The cleat is at least partially configured to be further from the pedal body in a first engagement state where the second cleat engagement surface engages with the second surface portion, compared to a second engagement state where the second cleat engagement surface engages with the second additional surface portion.

[0013] According to the bicycle pedal assembly of the fifth aspect, the bicycle pedal is more reliably fixed to the locking plate by using a first locking plate fixing member and a second locking plate fixing member.

[0014] According to a sixth aspect of this disclosure, the bicycle pedal assembly of the fifth aspect is configured such that a second slope of the second surface portion is inclined in a second inclined direction, the second surface portion is inclined away from the second additional surface portion in the second inclined direction, and approaches the pedal side surface as the second surface portion extends outward relative to the shoe attachment toward the outer edge of the cleat. A second additional slope of the second additional surface portion is inclined in a second additional inclined direction, the second additional surface portion is inclined away from the shoe side surface in the second additional inclined direction, and approaches the second surface portion as the second additional surface portion extends outward relative to the shoe attachment toward the outer edge of the cleat.

[0015] According to the bicycle pedal assembly of the sixth aspect, by using a first locking plate fixing member and a second locking plate fixing member, the bicycle pedal is more reliably fixed to the locking plate in both the first and second engaged states.

[0016] According to the seventh aspect of this disclosure, the bicycle pedal assembly according to any one of the third to sixth aspects is configured such that in a first engagement state, where the first locking plate engagement surface engages with the first surface portion, the extension line of the first reaction force vector at the engagement point of the first locking plate engagement surface and the first surface portion lies between the rotation center axis and the first pivot axis.

[0017] According to the bicycle pedal assembly of the seventh aspect, the locking plate fixing torque that pushes the first locking plate fixing member into the first engagement state is large, and when the locking plate is released from the pedal in a direction perpendicular to the pedal surface, the locking plate release torque received by the first locking plate fixing member is opposite to the locking plate fixing torque. Therefore, the magnitude of the resultant force of the two torques can be adjusted.

[0018] According to the eighth aspect of this disclosure, the bicycle pedal assembly according to any one of the third to seventh aspects is configured such that in a second engagement state where the first latch engagement surface is partially engaged with the first additional surface, the extension of the first additional reaction force vector at the engagement point of the first latch engagement surface and the first additional surface is located on the first pivot axis, or on the opposite side of the first pivot axis relative to the rotation center axis.

[0019] According to the bicycle pedal assembly of the eighth aspect, the locking plate fixing torque when pushing the first locking plate fixing member to the second engagement state is small, and when the locking plate is released from the pedal in a direction perpendicular to the pedal surface, the locking plate release torque received by the first locking plate fixing member is in the same direction as the locking plate fixing torque. Therefore, the magnitude of the resultant force of the two torques can be adjusted.

[0020] According to a ninth aspect of this disclosure, a bicycle pedal assembly according to any one of the third to eighth aspects is configured such that the bicycle pedal further includes a first pivot pin coupled to a pedal body. The first pivot pin defines a first pivot axis. A first latching member includes at least one pivot pin receiving opening having a dimension larger than the lateral dimension of the first pivot pin, such that during an engagement operation in which a latch is engaged to the pedal body via the first latching member, the first latching member is displaced on the first pivot pin relative to the first pivot axis.

[0021] According to the bicycle pedal assembly of the ninth aspect, since the first locking member can be displaced relative to the first pivot axis on the first pivot pin during the engagement operation of the locking member with the pedal body by means of the first locking member, the bicycle locking member can smoothly engage with the bicycle pedal.

[0022] According to the tenth aspect of this disclosure, the bicycle pedal assembly according to the ninth aspect is configured such that, compared to the position of the first locking plate fixing member in the second engaged state, the first locking plate fixing member is displaced on the first pivot pin in a direction away from the axis of rotation in the first engaged state.

[0023] According to the bicycle pedal assembly of the tenth aspect, the bicycle pedal can reliably secure the locking plate in each of the first engagement state and the second engagement state.

[0024] According to the eleventh aspect of this disclosure, the bicycle pedal assembly described in any one of the third to tenth aspects is configured such that, at the first contact point between the first surface portion and the first latch engagement surface engaged in a first engagement state, the inclination of the first slope of the first surface portion is greater than the inclination of the first tangent of the first reference circle centered on the first pivot axis and passing through the first contact point between the first surface portion and the first latch engagement surface.

[0025] According to the bicycle pedal assembly of aspect eleven, the bicycle pedal can reliably secure the locking plate in the first engaged state.

[0026] According to the twelfth aspect of this disclosure, the bicycle pedal assembly according to any one of the third to eleventh aspects is configured such that, at the second contact point between the first additional surface portion and the first locking plate engagement surface engaged in a second engagement state, the inclination of the first additional slope of the first additional surface portion is less than or equal to the inclination of the second tangent of the second reference circle centered on the first pivot axis and passing through the second contact point between the first surface portion and the first locking plate engagement surface.

[0027] According to the bicycle pedal assembly of the twelfth aspect, the bicycle pedal can reliably secure the locking plate in the second engaged state.

[0028] According to the thirteenth aspect of this disclosure, the bicycle pedal assembly according to any one of the third to twelfth aspects is configured such that the bicycle pedal further includes a first biasing member that biases the first locking plate retaining member toward the first locking plate about a first pivot axis.

[0029] According to the bicycle pedal assembly of aspect thirteen, after the locking plate engagement operation, the first locking plate retaining member can reliably return to the first locking plate holding position to secure the locking plate.

[0031] According to the bicycle pedal assembly of the fourteenth aspect, the first locking plate retaining member can be properly positioned to reliably engage and release the locking plate from the pedal.

[0032] According to a fifteenth aspect of this disclosure, a bicycle pedal system is provided, which substantially includes a first cleat, a second cleat, and a bicycle pedal. The first cleat includes a first shoe attachment having a first shoe side surface and a first pedal side surface, and a first cleat protrusion having a first surface portion with a first bevel. The second cleat includes a second shoe attachment having a second shoe side surface and a second pedal side surface, and a third cleat protrusion having a third surface portion with a third bevel. The first surface portion is spaced apart from the first shoe side surface by a first distance. The third surface portion is spaced apart from the second shoe side surface by a second distance, the second distance being different from the first distance. The bicycle pedal is configured to interchangeably and releasably secure each of the first and second cleats. The bicycle pedal includes a pedal axle, a pedal body, and a first cleat securing member. The pedal axle has a rotational central axis. The pedal body is rotatably disposed about the rotational central axis. The first cleat securing member is pivotally disposed to the pedal body about a first pivot axis. The first cleat securing member has a first cleat engaging surface. In a first engaged state where the bicycle pedal secures the first cleat, the first cleat engaging surface contacts the first surface portion of the first cleat protrusion. In the second engaged state where the second locking plate is fixed to the bicycle pedal, the engaging surface of the first locking plate contacts the third surface portion of the protruding third locking plate. The first locking plate is at least partially configured to be farther from the pedal body in the first engaged state compared to the second locking plate in the second engaged state.

[0033] According to the bicycle pedal system of the fifteenth aspect, the bicycle pedals can interchangeably and releasably secure each of the first and second locking plates, thereby enabling appropriate engagement states for locking plates of different shapes.

The second locking plate further includes a fourth locking plate protrusion having a fourth surface portion with a fourth bevel. The bicycle pedal further includes a second locking plate fixing member pivotally disposed to the pedal body about a second pivot axis. The second locking plate fixing member includes a second locking plate engaging surface. In a first engaged state where the bicycle pedal fixes the first locking plate, the second locking plate engaging surface contacts the second surface portion of the second locking plate protrusion. In a second engaged state where the bicycle pedal fixes the second locking plate, the second locking plate engaging surface contacts the fourth surface portion of the fourth locking plate protrusion.

[0035] According to the bicycle pedal system of the sixteenth aspect, the bicycle pedal is more reliably fixed to the locking plate by using a first locking plate fixing member and a second locking plate fixing member.

[0036] According to the seventeenth aspect of this disclosure, the bicycle pedal system according to the fifteenth or sixteenth aspect is configured such that the bicycle pedal further includes a first biasing member that biases the first locking plate retaining member toward the first locking plate about a first pivot axis.

[0037] According to the bicycle pedal system of the seventeenth aspect, after the locking plate engagement operation, the first locking plate fixing member can reliably return to the first locking plate holding position to fix the locking plate.

[0038] According to the eighteenth aspect of this disclosure, a bicycle pedal system according to any one of the fifteenth to seventeenth aspects is configured such that a first pivot axis is offset from the axis of rotation center.

[0039] According to the bicycle pedal system of the eighteenth aspect, the first locking plate fixing member can be properly positioned to reliably engage and release the locking plate from the pedal.

Detailed Implementation

[0090] Selected embodiments will now be explained with reference to the accompanying drawings. Based on this disclosure, those skilled in the art of bicycles will understand that the following description of the embodiments is merely illustrative and not intended to limit the invention to the extent defined by the appended claims and their equivalents.

[0091] First refer to Figure 1 The image shows a bicycle pedal assembly 10 according to an exemplary embodiment. Figure 1 As shown, the bicycle pedal assembly 10 generally includes a bicycle pedal 12 and a clip 14. The clip 14 is conventionally attached to the cycling shoe S by a pair of fasteners F (e.g., a pair of screws). The bicycle pedal 12 is a clip-on or in-feed pedal configured to releasably secure the clip 14 to it. Here, the bicycle pedal 12 is the left bicycle pedal. The bicycle pedal assembly 10 may also include a right bicycle pedal and an additional clip. As needed and / or desired, the right bicycle pedal may be the same as or a mirror image of the bicycle pedal 12 (i.e., the left bicycle pedal). Therefore, the description of the bicycle pedal 12 applies to both the left and right bicycle pedals. Thus, only one bicycle pedal is shown in the figures and discussed below.

[0092] Bicycle pedal 12 is mounted to the crank arm CA of bicycle B so that it rotates together with the crank arm CA. For example... Figure 1 As shown, the clip 14 is mounted to the bottom surface of the sole of the bicycle shoe S via fastener F. The bicycle pedal 12 is configured to releasably secure the clip 14. In other words, the clip 14 is configured to be releasably secured to the bicycle pedal 12. The clip 14 is configured to be attached to the bicycle pedal 12 in such a way that it allows limited rotational movement, but when the rotational movement of the clip 14 exceeds a predetermined angular movement relative to the bicycle pedal 12, the clip 14 is released from the bicycle pedal 12.

[0093] like Figures 2 to 4As shown, the bicycle pedal 12 generally includes a pedal shaft 20, a pedal body 22, and a first cleat fixing member 24. Preferably, the bicycle pedal 12 also includes a second cleat fixing member 26. In the illustrated embodiment, the cleat 14 is held to the pedal body 22 by the first cleat fixing member 24 and the second cleat fixing member 26. The bicycle cleat 14 is also referred to as a dual-position cleat 14, as described below. Therefore, the terms "cleat 14" and "dual-position cleat 14" are used interchangeably herein. Preferably, the bicycle cleat 14 generally includes a shoe attachment 14a and a first cleat protrusion 14b. In other words, the dual-position cleat 14 (also referred to as cleat 14) includes a shoe attachment 14a and a first dual-position cleat protrusion 14b (also referred to as the first cleat protrusion 14b). In the illustrated embodiment, as... Figures 12 to 20 As shown, the latch 14 also includes a second latch protrusion 14c. In other words, in the illustrated embodiment, the dual-position latch 14 (also referred to as latch 14) further includes a second dual-position latch protrusion 14c (also referred to as second latch protrusion 14c). The shoe attachment 14a has a shoe side surface 14a1 and a pedal side surface 14a2. The shoe side surface 14a1 faces the shoe S, while the pedal side surface 14a2 faces the pedal body 22. When the latch 14 is secured to the pedal body 22, the first latch retaining member 24 engages the first latch protrusion 14b, and the second latch protrusion 14c engages the second latch retaining member 26, as described below. Also as described below, the first latch protrusion 14b and the second latch protrusion 14c are configured to engage with the first latch retaining member 24 and the second latch retaining member 26 to be held in two different positions relative to the pedal body 22. The pedal shaft 20 has a rotation center axis R1. The pedal body 22 is rotatably disposed relative to the pedal shaft 20. Specifically, the pedal body 22 is rotatably mounted around the rotation center axis R1.

[0094] like Figure 3 and Figure 8 As shown, the pedal shaft 20 is a rigid member that rotatably supports the pedal body 22 in a conventional manner. The pedal shaft 20 is preferably made of a rigid material such as metal or fiber-reinforced material. The pedal shaft 20 has an externally threaded section 20a and a support section 20b. The externally threaded section 20a is configured to screw into the crank arm CA. The support section 20b is used to rotatably support the pedal body 22 via one or more bearings.

[0095] like Figure 4 and Figure 5As shown, the pedal body 22 is a rigid member with an overall H-shape, used to pivotally support the first locking plate fixing member 24 and the second locking plate fixing member 26. The pedal body 22 is preferably made of a rigid material such as metal or fiber-reinforced material. The first locking plate fixing member 24 is pivotally disposed to the pedal body 22 about a first pivot axis P1. Specifically, the first locking plate fixing member 24 is configured to pivot about the first pivot axis P1 between a first locking plate holding position and a first locking plate non-holding position. On the other hand, the second locking plate fixing member 26 is pivotally disposed to the pedal body 22 about a second pivot axis P2. Specifically, the second locking plate fixing member 26 is configured to pivot about the second pivot axis P2 between a second locking plate holding position and a second locking plate non-holding position. The second locking plate fixing member 26 is disposed on the pedal body 22 and spaced apart from the first locking plate fixing member 24 to form a locking plate receiving area A1 therebetween.

[0096] like Figure 24 As shown, viewed from a direction parallel to the rotation center axis R1, the rotation center axis R1 is located between the first pivot axis P1 and the second pivot axis P2. The first pivot axis P1 is offset from the rotation center axis R1. The second pivot axis P2 is offset from both the rotation center axis R1 and the first pivot axis P1. Furthermore, as... Figure 4 and Figure 5 As shown, the rotation center axis R1, the first pivot axis P1, and the second pivot axis P2 are parallel to each other. Figure 24 As shown, the rotation center axis R1, the first pivot axis P1, and the second pivot axis P2 are completely contained within a single reference plane RP1. In other words, the single reference plane RP1 completely includes the rotation center axis R1, the first pivot axis P1, and the second pivot axis P2. The single reference plane RP1 may also completely include two other than one of the rotation center axis R1, the first pivot axis P1, and the second pivot axis P2.

[0097] In this embodiment, such as Figures 11 to 20 As shown, both the first locking plate retaining member 24 and the second locking plate retaining member 26 are movable relative to the pedal body 22 to secure and release the locking plate 14. Alternatively, one of the first locking plate retaining member 24 and the second locking plate retaining member 26 may be configured to be a fixed or immovable member during engagement of the locking plate 14 with the pedal body 22 and during release of the locking plate 14 from the pedal body 22.

[0098] In this embodiment, such as Figure 6 and Figure 7As shown, the bicycle pedal 12 also includes a pedal body 28. The pedal body 28 has a first pedal surface 28a and a second pedal surface 28b. The first pedal surface 28a and the second pedal surface 28b face opposite directions. The pedal body 28 substantially surrounds the pedal body 22. The pedal body 28 is rotatably supported relative to the pedal axle 20 to rotate about the rotational center axis R1 of the pedal axle 20. Therefore, both the pedal body 22 and the pedal body 28 rotate about the rotational center axis R1 of the pedal axle 20. Furthermore, the pedal body 22 and the pedal body 28 are configured to pivot relative to each other with a predetermined angular movement. In other words, the pedal body 22 is rotatably disposed relative to the pedal axle 20 to rotate about the rotational center axis R1, and pivots relative to the pedal body 28 about the rotational center axis R1. Alternatively, the pedal body 28 may be fixed relative to the pedal body 22 such that the pedal body 28 does not pivot relative to the pedal body 22. For example, the pedal body 28 may be integrally formed with the pedal body 22. Alternatively, the stepping body 28 can be omitted.

[0099] Here, as Figure 3 , Figure 7 and Figure 8 As shown, the bicycle pedal 12 also includes a support member 29, which is connected to the pedal body 28 by a pair of fasteners 30. Here, the fasteners 30 are screws. The pedal shaft 20 passes through an opening in the support member 29. The support member 29 is configured to restrict the bending of the pedal shaft 20. The pedal body 28 is attached to the pedal shaft 20 by fasteners 31. Here, the fasteners 31 are fixing screws screwed into threaded holes formed at the ends of the pedal shaft 20.

[0100] like Figures 11 to 18As shown, the bicycle pedal 12 also includes a biasing element 32. The biasing element 32 is operatively disposed between the pedal body 28 and the pedal body 22 to bias the pedal body 22 relative to the pedal body 28 to a neutral rest position. Here, the biasing element 32 is a torsion spring disposed on the fastener 31 and located between the pedal body 22 and the pedal body 28. Specifically, in the illustrated embodiment, the biasing element 32 has a helical portion 32a, a first leg 32b, and a second leg 32c. The first leg 32b and the second leg 32c extend from the helical portion 32a and intersect each other. The first leg 32b and the second leg 32c contact a protrusion 28c of the pedal body 28 and a protrusion 22a of the pedal body 22. For example, in the neutral rest position, the first leg 32b and the second leg 32c contact the protrusion 28c of the pedal body 28 and the protrusion 22a of the pedal body 22. When viewed from the direction of the rotation center axis R1, the protrusion 28c is located between the first leg 32b and the second leg 32c. When viewed from the direction of the rotation center axis R1, the protrusion 22a of the pedal body 22 is located between the first leg 32b and the second leg 32c. The engagement of the first leg 32b and the second leg 32c with the protrusion 28c of the pedal body 28 and the protrusion 22a of the pedal body 22 maintains the pedal body 22 in a neutral, stationary position relative to the pedal body 28. Figure 12 and Figure 16 As shown, the pedal body 22 can pivot relative to the pedal body 28 against the biasing force of the biasing element 32. For example, as Figure 12 As shown, the locking plate 14 can press against the first locking plate fixing member 24 to deflect the second leg 32c and pivot the pedal body 22 relative to the pedal body 28. The second leg 32c is pushed by the protrusion 22a in the circumferential direction relative to the axis R1 to generate a spring force relative to the protrusion 22a in the circumferential direction. The first leg 32b is held in the same position as the neutral rest position by the protrusion 28c. Furthermore, for example, as... Figure 16 As shown, the locking plate 14 can be pressed against the second locking plate fixing member 26 to deflect the first leg 32b and pivot the pedal body 22 relative to the pedal body 28. The first leg 32b is pushed by the protrusion 22a in the circumferential direction relative to the axis R1 to generate a spring force relative to the protrusion 22a in the circumferential direction. The second leg 32c is held in the same position as the neutral rest position by the protrusion 28c. These spring forces are used to return the pedal body 22 to the neutral rest position relative to the pedal body 28.

[0101] In the illustrated embodiment, the bicycle pedal 12 is a double-sided bicycle pedal, meaning that the locking plate 14 can be releasably secured to either side of the bicycle pedal 12. Therefore, the bicycle pedal 12 is specifically designed for off-road bicycles, rather than for road bicycles. However, as will be apparent to those skilled in the art of bicycles according to this disclosure, the structure of the bicycle pedal 12 can be modified for road-type bicycle pedals if desired and / or desired. In other words, it is evident that the bicycle pedal 12 can be designed such that the locking plate 14 can only be engaged to one side of the bicycle pedal 12.

[0102] Therefore, in this embodiment, as Figures 5 to 7 As shown, the bicycle pedal also includes a third cleat fixing member 34. The third cleat fixing member 34 is pivotally supported to the pedal body 22 between a third cleat holding position and a third cleat non-holding position, pivoting about a first pivot axis P1. Furthermore, in this embodiment, the bicycle pedal also includes a fourth cleat fixing member 36. The fourth cleat fixing member 36 is pivotally disposed to the pedal body 22 about a second pivot axis P2 between a fourth cleat holding position and a fourth cleat non-holding position. Here, the third cleat fixing member 34 and the fourth cleat fixing member 36 are disposed to the pedal body 22 and spaced apart to form a cleat receiving area A2 between them.

[0103] The bicycle pedal 12 also includes a first pivot pin 40 connected to the pedal body 22. A first latch retaining member 24 is pivotally connected to the pedal body 22 via the first pivot pin 40. The first pivot pin 40 defines a first pivot axis P1. The first latch retaining member 24 is configured to at least partially protrude from the pedal body 28 relative to the first pedal surface 28a when the pedal body 22 is in a neutral, stationary position relative to the pedal body 28. In this way, during the engagement operation of the latch 14 to the pedal body 22, the latch 14 can be engaged with the first latch retaining member 24 by hooking the latch 14 onto the first latch retaining member 24 or by pressing the latch 14 against the first latch retaining member 24.

[0104] like Figure 6 and Figure 7As shown, the first locking plate retaining member 24 includes a first locking plate engagement surface 24a. The first locking plate engagement surface 24a is spaced outward from the footrest body 28 relative to the first footrest surface 28a. Furthermore, the first locking plate retaining member 24 also includes a first inclined surface 24b, which is arranged to receive locking plate clamping force during engagement operation of the locking plate 14 and the first locking plate retaining member 24 to cause the first locking plate retaining member 24 to pivot about a first pivot axis P1. In the neutral rest position, the first inclined surface 24b is inclined relative to a reference plane RP1 that completely encompasses the first pivot axis P1 and the second pivot axis P2. The first locking plate retaining member 24 includes at least one pivot pin receiving opening. Specifically, as... Figure 10 As shown, the first locking plate retaining member 24 further includes a pair of mounting flanges 24c for pivotally mounting the first locking plate retaining member 24 to the pedal body 22 via the first pivot pin 40. Preferably, each mounting flange 24c includes a pivot pin receiving opening 24c1 for receiving the first pivot pin 40. Each pivot pin receiving opening 24c1 has a dimension larger than the lateral dimension of the first pivot pin 40, such that during engagement operation in which the locking plate 14 engages with the pedal body 22 via the first locking plate retaining member 24, the first locking plate retaining member 24 is displaced relative to the first pivot axis P1 on the first pivot pin 40.

[0105] The second locking plate retaining member 26 is pivotally connected to the pedal body 22 via a second pivot pin 42 defining a second pivot axis P2. Similar to the first locking plate retaining member 24, the second locking plate retaining member 26 is configured to at least partially protrude from the pedal body 28 relative to the first pedal surface 28a when the pedal body 22 is in a neutral, stationary position relative to the pedal body 28. In this way, during the engagement operation of the locking plate 14 to the pedal body 22, the locking plate 14 can engage the second locking plate retaining member 26 by hooking the locking plate 14 onto the second locking plate retaining member 26 or by pressing the locking plate 14 against the second locking plate retaining member 26.

[0106] like Figure 6 and Figure 7As shown, the second locking plate retaining member 26 includes a second locking plate engagement surface 26a. The second locking plate engagement surface 26a is spaced outward from the pedal body 28 relative to the first pedal surface 28a. Furthermore, the second locking plate retaining member 26 also includes a second inclined surface 26b, which is arranged to receive locking plate clamping force during engagement operation of the locking plate 14 and the second locking plate retaining member 26 to pivot the second locking plate retaining member 26 about a second pivot axis P2. In the neutral rest position, the second inclined surface 26b is inclined relative to the reference plane RP1. The second locking plate retaining member 26 also includes a pair of mounting flanges 26c for pivotally mounting the second locking plate retaining member 26 to the pedal body 22 via a second pivot pin 42. Here, as... Figure 10 As shown, each mounting flange 26c includes a pivot pin receiving opening 26c1 for receiving the second pivot pin 42.

[0107] The third locking plate retaining member 34 is pivotally connected to the pedal body 22 via the first pivot pin 40. The third locking plate retaining member 34 is configured to at least partially protrude from the pedal body 28 relative to the second pedal surface 28b when the pedal body 22 is in a neutral, stationary position relative to the pedal body 28. In this way, during the engagement operation of the locking plate 14 to the pedal body 22, the locking plate 14 can be engaged by hooking the locking plate 14 onto the third locking plate retaining member 34 or by pressing the locking plate 14 against the third locking plate retaining member 34.

[0108] The fourth locking plate retaining member 36 is pivotally connected to the pedal body 22 via the second pivot pin 42. Similar to the third locking plate retaining member 34, the fourth locking plate retaining member 36 is configured to at least partially protrude from the pedal body 28 relative to the second pedal surface 28b when the pedal body 22 is in a neutral, stationary position relative to the pedal body 28. In this way, during the engagement operation of the locking plate 14 to the pedal body 22, the locking plate 14 can engage the third locking plate retaining member 34 and / or the fourth locking plate retaining member 36 in the same manner as the first locking plate retaining member 24 and the second locking plate retaining member 26.

[0109] like Figure 6 and Figure 7As shown, the third locking plate retaining member 34 includes a third locking plate engagement surface 34a, which is spaced outward from the pedal body 28 relative to the second pedal surface 28b. Furthermore, the third locking plate retaining member 34 also includes a third inclined surface 34b, arranged to receive locking plate clamping force during engagement operation of the locking plate 14 and the third locking plate retaining member 34, causing the third locking plate retaining member 34 to pivot about a first pivot axis P1. In the neutral, stationary position, the third inclined surface 34b is inclined relative to the reference plane RP1. The third locking plate retaining member 34 also includes a pair of mounting flanges 34c for pivotally mounting the third locking plate retaining member 34 to the pedal body 22 via a first pivot pin 40. Here, as... Figure 10 As shown, each mounting flange 34c includes a pivot pin receiving opening 34c1 for receiving the first pivot pin 40.

[0110] like Figure 6 and Figure 7 As shown, the fourth locking plate retaining member 36 includes a fourth locking plate engagement surface 36a, which is spaced outward from the pedal body 28 relative to the second pedal surface 28b. Furthermore, the fourth locking plate retaining member 36 also includes a fourth inclined surface 36b, arranged to receive locking plate clamping force during engagement operation of the locking plate 14 and the fourth locking plate retaining member 36, causing the fourth locking plate retaining member 36 to pivot about the second pivot axis P2. In the neutral rest position, the fourth inclined surface 36b is inclined relative to the reference plane RP1. The fourth locking plate retaining member 36 also includes a pair of mounting flanges 36c for pivotally mounting the fourth locking plate retaining member 36 to the pedal body 22 via the second pivot pin 42. Here, as... Figure 10 As shown, each mounting flange 36c includes a pivot pin receiving opening 36c1 for receiving the second pivot pin 42.

[0111] refer to Figures 11 to 20 The figure illustrates three different locking plate engagement operations. Specifically, during the engagement operation of the locking plate 14 to the pedal body 22, one of the first locking plate retaining member 24 and the second locking plate retaining member 26 pivots, or both the first locking plate retaining member 24 and the second locking plate retaining member 26 pivot.

[0112] For example, Figures 11 to 15 This illustrates a locking engagement operation in which only the first locking plate retaining member 24 pivots relative to the pedal body 22 to secure the locking plate 14 to the pedal body 22 via the first locking plate retaining member 24 and the second locking plate retaining member 26. Specifically, as... Figure 12 As shown, the cyclist can press the clip 14 downwards onto the first clip retaining member 24, causing the second clip retaining member 26 to move upwards to a position further above the pedal surface 28a. Then, as... Figure 13 As shown, the cyclist can slide the locking plate 14 along direction D1, such that the second locking plate protrusion 14c of the locking plate 14 is located under the second locking plate engagement surface 26a. Direction D1 is perpendicular to the rotation center axis R1, parallel to the reference plane RP1, and is the direction from the first locking plate fixing member 24 to the second locking plate fixing member 26. Now, as Figure 14 As shown, the rider can further press down on the locking plate 14 to cause the first locking plate fixing member 24 to pivot relative to the pedal body 22, thereby fixing the locking plate 14 to the pedal body 22 via the first locking plate fixing member 24 and the second locking plate fixing member 26. Furthermore, by pushing the locking plate 14 against the second locking plate fixing member 26 in direction D1, the pedal body 22 rotates in direction X1 about the rotation center axis R1 relative to the pedal body 28, as shown. Figure 14 As shown. Direction X1 is the direction of rotation of the pedal body 22 about the rotation axis R1, so that the first locking plate fixing member 24 protrudes relative to the first pedal surface 28a of the pedal body 28 with respect to the neutral rest position. As a result, the first locking plate fixing member 24 protrudes further from the first pedal surface 28a. Now, as Figure 15 As shown, the locking plate 14 is secured to the pedal body 22 by a first locking plate fixing member 24 and a second locking plate fixing member 26. In this example, the second locking plate fixing member 26 does not move relative to the pedal body 22 during the engagement operation of the locking plate 14 with the pedal body 22. Alternatively, the second locking plate fixing member 26 may be configured to move relative to the pedal body 22 during the engagement operation of the locking plate 14 with the pedal body 22.

[0113] Alternatively, for example, Figures 16 to 18 This illustrates a locking engagement operation in which only the second locking plate retaining member 26 pivots relative to the pedal body 22 to secure the locking plate 14 to the pedal body 22 via the first locking plate retaining member 24 and the second locking plate retaining member 26. Specifically, as... Figure 16 As shown, the cyclist can press the clip 14 downwards onto the second clip retaining member 26, causing the first clip retaining member 24 to move upwards to a position further above the pedal surface 28a. Then, as... Figure 17 As shown, the cyclist can slide the locking plate 14 along direction D2, such that the first locking plate protrusion 14b of the locking plate 14 is located under the first locking plate engagement surface 24a. Direction D2 is perpendicular to the rotation center axis R1, parallel to the reference plane RP1, and is the direction from the second locking plate fixing member 26 to the first locking plate fixing member 24. Direction D2 is opposite to direction D1. Now, as Figure 18As shown, the rider can further press down on the locking plate 14, causing the second locking plate fixing member 26 to pivot relative to the pedal body 22, thereby fixing the locking plate 14 to the pedal body 22 via the first locking plate fixing member 24 and the second locking plate fixing member 26. Furthermore, by pushing the locking plate 14 against the first locking plate fixing member 24 in direction D2, the pedal body 22 rotates in direction X2 about the rotation center axis R1 relative to the pedal body 28, as shown. Figure 18 As shown. Direction X2 is the direction of rotation of the pedal body 22 about the rotation axis R1, so that the second locking plate fixing member 26 protrudes relative to the first pedal surface 28a of the pedal body 28 with respect to the neutral rest position. Direction X2 is opposite to direction X1. As a result, the second locking plate fixing member 26 protrudes further from the first pedal surface 28a. Now, as Figure 15 As shown, the locking plate 14 is secured to the pedal body 22 by a first locking plate fixing member 24 and a second locking plate fixing member 26. In this example, the first locking plate fixing member 24 does not move relative to the pedal body 22 during the engagement operation of the locking plate 14 with the pedal body 22. Alternatively, the first locking plate fixing member 24 may be configured to move relative to the pedal body 22 during the engagement operation of the locking plate 14 with the pedal body 22.

[0114] In addition, for example, Figure 19 and Figure 20 The diagram illustrates a locking engagement operation in which the first locking plate retaining member 24 and the second locking plate retaining member 26 both pivot relative to the pedal body 22, thereby securing the locking plate 14 to the pedal body 22 via the first locking plate retaining member 24 and the second locking plate retaining member 26. Here, as... Figure 19 and Figure 20 As shown, during the engagement operation of the locking plate 14 with the pedal body 22, the locking plate 14 can be pressed downwards simultaneously onto both the first locking plate retaining member 24 and the second locking plate retaining member 26, so that both the first locking plate retaining member 24 and the second locking plate retaining member 26 pivot from the locking plate non-retaining position to the locking plate retaining position. As a result, as... Figure 15 As shown, the locking plate 14 is fixed to the pedal body 22 by the first locking plate fixing member 24 and the second locking plate fixing member 26.

[0115] like Figure 4 and Figure 10As shown, the bicycle pedal 12 also includes a first biasing member 50. Here, the first biasing member 50 includes a torsion spring. The first biasing member 50 is operatively disposed between the pedal body 22 and the first latch retaining member 24. The first biasing member 50 biases the first latch retaining member 24 about a first pivot axis P1 toward a first latch holding position. Specifically, the first biasing member 50 is configured to apply a first biasing force to the first latch retaining member 24 to bias the first latch retaining member 24 about the first pivot axis P1 toward a first latch holding position. Figure 26 and 27 As shown, the first biasing member 50 has a spiral portion 50a, a first leg 50b, and a second leg 50c. The first leg 50b contacts the abutment portion 24d of the first locking plate fixing member 24 to bias the first locking plate fixing member 24 toward the first locking plate holding position.

[0116] like Figure 4 and Figure 10 As shown, the bicycle pedal 12 also includes a second biasing member 52. Here, the second biasing member 52 includes a torsion spring. The second biasing member 52 is operatively disposed between the pedal body 22 and the second latch retaining member 26. The second biasing member 52 biases the second latch retaining member 26 about a second pivot axis P2 toward a second latch holding position. Specifically, the second biasing member 52 is configured to apply a second biasing force to the second latch retaining member 26 to bias the second latch retaining member 26 about a second pivot axis P2 toward a second latch holding position. The second biasing member 52 has the same construction as the first biasing member 50. The second biasing member 52 contacts the abutment portion 26d of the second latch retaining member 26 and applies a biasing force toward the second latch retaining member 26 toward the second latch holding position.

[0117] like Figure 5 and Figure 10 As shown, the bicycle pedal 12 also includes a third biasing member 54. Here, the third biasing member 54 includes a torsion spring operably disposed between the pedal body 22 and the third latch retaining member 34. The third biasing member 54 biases the third latch retaining member 34 about a first pivot axis P1 toward a third latch holding position. The third biasing member 54 is configured to apply a third biasing force to the third latch retaining member 34 to hold the third latch retaining member 34 about the first pivot axis P1 toward the third latch holding position. The third biasing member 54 has the same construction as the first biasing member 50. The third biasing member 54 contacts the abutment portion 34d of the third latch retaining member 34 and applies a biasing force toward the third latch retaining member 34 toward the third latch holding position.

[0118] like Figure 5 and Figure 10As shown, the bicycle pedal 12 also includes a fourth biasing member 56. Here, the fourth biasing member 56 includes a torsion spring operably disposed between the pedal body 22 and the fourth latch retaining member 36. The fourth biasing member 56 biases the fourth latch retaining member 36 about a second pivot axis P2 toward a fourth latch holding position. The fourth biasing member 56 is configured to apply a fourth biasing force to the fourth latch retaining member 36 to bias the fourth latch retaining member 36 about the second pivot axis P2 toward the fourth latch holding position. The fourth biasing member 56 has the same construction as the first biasing member 50. The fourth biasing member 56 contacts the abutment portion 36d of the fourth latch retaining member 36 and applies a biasing force toward the fourth latch retaining position to the fourth latch retaining member 36.

[0119] In the illustrated embodiment, such as Figure 4 and Figure 5 As shown, the first biasing member 50 and the third biasing member 54 are supported on the pedal body 22 by the first support member 60. Specifically, the helical portion 50a of the first biasing member 50 is supported on the first support member 60. Similarly, the helical portion of the third biasing member 54 is supported on the first support member 60. Essentially, the first support member 60 is a round bar or shaft fixed to the pedal body 22. More specifically, the first support member 60 includes a threaded section for releasably securing the first support member 60 to the pedal body 22. The first support member 60 passes through the opening 24c2 of the mounting flange 24c and the opening 34c2 of the mounting flange 34c. This contact between the first support member 60 and the mounting flange 24c of the first locking plate retaining member 24 establishes a stationary or non-retaining position for the first locking plate retaining member 24. Similarly, this contact between the first support member 60 and the mounting flange 34c of the third locking plate retaining member 34 establishes a stationary or non-retaining position for the third locking plate retaining member 34.

[0120] Furthermore, in the illustrated embodiments, such as Figure 4 and Figure 5As shown, the second biasing member 52 and the fourth biasing member 56 are supported on the pedal body 22 by the second support member 62. Specifically, the helical portions of the second biasing member 52 and the fourth biasing member 56 are supported on the second support member 62. Essentially, the second support member 62 is a round bar or shaft fixed to the pedal body 22. More specifically, the second support member 62 includes a threaded section for releasably securing the second support member 62 to the pedal body 22. The second support member 62 passes through the openings 26c2 of the mounting flange 26c and 36c2 of the mounting flange 36c. This contact between the second support member 62 and the mounting flange 26c of the second locking member 26 establishes a stationary or non-retaining position for the second locking member 26. Similarly, this contact between the second support member 62 and the mounting flange 36c of the fourth locking member 36 establishes a stationary or non-retaining position for the fourth locking member 36. Here, the head of the second support member 62 forms a protrusion 22a of the pedal body 22. As described above, the protrusion 22a (the head of the second support member 62) contacts the first leg 32b and the second leg 32c of the biasing element 32. The first biasing member 50 and the third biasing member 54 can be disposed on the first pivot pin 40. Therefore, the first support member 60 can be omitted. Similarly, the second biasing member 52 and the fourth biasing member 56 can be disposed on the second pivot pin 42. Therefore, the second support member 62 can be omitted.

[0121] like Figure 4 , Figure 10 and Figures 21 to 23 As shown, the bicycle pedal 12 also includes a first resistance member 64. The first resistance member 64 is disposed to the pedal body 22 via a first support member 60. The first resistance member 64 is configured to apply a first resistance to the latch 14 in addition to a first biasing force during the disengagement operation of the latch from the first latch retaining member 24 and the second latch retaining member 26. Therefore, the first resistance member 64 increases the disengagement force required to disengage the latch 14 from the first latch retaining member 24 and the second latch retaining member 26.

[0122] In addition, such as Figures 21 to 23As shown, the first resistance member 64 is configured not to apply a first resistance to the first locking plate retaining member 24. More specifically, the first resistance member 64 is configured not to apply a first resistance to the locking plate 14 during engagement operations with the first locking plate retaining member 24 and the second locking plate retaining member 26. In other words, the first resistance member 64 is configured such that the engagement force required for the locking plate 14 to engage with the first locking plate retaining member 24 and the second locking plate retaining member 26 does not increase. In the illustrated embodiment, the first resistance member 64 is spaced apart from the locking plate 14 when the locking plate 14 is fixed to the pedal body 22 by the first locking plate retaining member 24 and the second locking plate retaining member 26. Furthermore, the first resistance member 64 is configured to contact the locking plate 14 when the locking plate 14 is twisted during disengagement operations from the first locking plate retaining member 24 and the second locking plate retaining member 26. Alternatively, the first resistance member 64 may be configured to contact the locking plate 14 during engagement operations, but the first resistance during engagement operations may be less than the first resistance during disengagement operations.

[0123] In the illustrated embodiment, such as Figure 10 and Figures 21 to 23As shown, the first resistance member 64 includes a first locking tab contact member 64A and a first elastic member 64B. The first locking tab contact member 64A is configured to contact the locking tab 14 and resist the elastic movement of the first elastic member 64B during the disengagement operation of the locking tab 14 from the first locking tab retaining member 24 and the second locking tab retaining member 26. More specifically, the first locking tab contact member 64A is configured to contact a first lateral surface of the locking tab 14 during the disengagement operation of the locking tab 14 from the first locking tab retaining member 24 and the second locking tab retaining member 26. In the illustrated embodiment, the first locking tab contact member 64A includes a first protrusion 64A1, which is arranged in the path of the locking tab 14 when the locking tab 14 is twisted during the disengagement operation. Due to this contact between the locking tab 14 and the first protrusion 64A1 of the first locking tab contact member 64A, the first locking tab contact member 64A resists the elastic movement of the first elastic member 64B during the disengagement operation of the locking tab 14. In other words, during the disengagement operation of the locking plate 14, the first protrusion 64A1 resists the elastic movement of the first elastic member 64B. Here, the first elastic member 64B includes a torsion spring. In the illustrated embodiment, the first elastic member 64B includes a third biasing member 54. In other words, in the illustrated embodiment, a single torsion spring is used for both the third biasing member 54 and the first elastic member 64B. In the illustrated embodiment, the first locking plate retaining member 24 is disposed between the first resistance member 64 and the first biasing member 50. Alternatively, a separate torsion spring can be provided for each of the third biasing member 54 and the first elastic member 64B. In the illustrated embodiment, the first protrusion 64A1 of the first locking plate contact member 64A is biased by the first elastic member 64B to rotate toward the pedal shaft 20. That is, the first protrusion 64A1 of the first locking plate contact member 64A is biased to approach the pedal shaft 20. One arm of the torsion spring of the first elastic member 64B biases the third locking plate retaining member 34, while the other arm biases the first locking plate contact member 64A. The first locking contact member 64A contacts the first pivot pin 40 and is positioned in the circumferential direction relative to the first support member 60.

[0124] like Figure 4 , Figure 10 and Figures 21 to 24 As shown, the bicycle pedal 12 also includes a second resistance member 66. The second resistance member 66 is disposed to the pedal body 22 via a second support member 62. The second resistance member 66 is configured to apply a second resistance to the locking plate 14 in addition to the second biasing force during the disengagement operation of the locking plate 14 from the first locking plate retaining member 24 and the second locking plate retaining member 26. Therefore, the second resistance member 66 increases the disengagement force required to disengage the locking plate 14 from the first locking plate retaining member 24 and the second locking plate retaining member 26.

[0125] In addition, such as Figures 21 to 24As shown, the second resistance member 66 is configured not to apply a second resistance to the first locking plate retaining member 24. Furthermore, the second resistance member 66 is configured not to apply a second resistance to the second locking plate retaining member 26. More specifically, the second resistance member 66 is configured not to apply a second resistance to the locking plate 14 during the engagement operation between the locking plate 14 and the first locking plate retaining member 24 and the second locking plate retaining member 26. In other words, the second resistance member 66 is configured such that the engagement force required to engage the locking plate 14 with the first locking plate retaining member 24 and the second locking plate retaining member 26 does not increase. In the illustrated embodiment, the second resistance member 66 is spaced apart from the locking plate 14 when the locking plate 14 is fixed to the pedal body 22 by the first locking plate retaining member 24 and the second locking plate retaining member 26, and the second resistance member 66 is configured to contact the locking plate 14 when the locking plate 14 is twisted during the disengagement operation from the first locking plate retaining member 24 and the second locking plate retaining member 26. Alternatively, the second resistance member 66 may be configured to contact the locking piece 14 during engagement, but the second resistance during engagement may be configured to be less than the second resistance during disengagement.

[0126] In the illustrated embodiment, such as Figure 10 and Figures 21 to 24 As shown, the second resistance member 66 includes a second locking tab contact member 66A and a second elastic member 66B. The second locking tab contact member 66A is configured to contact the locking tab 14 and resist the elastic movement of the second elastic member 66B during the disengagement operation of the locking tab 14 from the first locking tab retaining member 24 and the second locking tab retaining member 26. More specifically, the second locking tab contact member 66A is configured to contact a second lateral surface of the locking tab 14 during the disengagement operation of the locking tab 14 from the first locking tab retaining member 24 and the second locking tab retaining member 26. In the illustrated embodiment, the second locking tab contact member 66A includes a second protrusion 66A1, which is arranged in the path of the locking tab 14 when the locking tab 14 is twisted during the disengagement operation. Due to this contact between the locking tab 14 and the second protrusion 66A1, the second locking tab contact member 66A resists the elastic movement of the second elastic member 66B during the disengagement operation of the locking tab 14. In other words, during the disengagement operation of the locking piece 14, the second protrusion 66A1 resists the elastic movement of the second elastic member 66B.

[0127] In the illustrated embodiment, the second elastic member 66B includes a torsion spring. Here, the second elastic member 66B includes a fourth biasing member 56. In other words, in the illustrated embodiment, a single torsion spring is used for both the fourth biasing member 56 and the second elastic member 66B. In the illustrated embodiment, the second locking member 26 is disposed between the second resistance member 66 and the second biasing member 52. Alternatively, a separate torsion spring can be provided for each of the fourth biasing member 56 and the second elastic member 66B.

[0128] In the illustrated embodiment, such as Figure 22 and Figure 23 As shown, during the latch disengagement operation, latch 14 simultaneously contacts the first protrusion 64A1 of the first resistance member 64 and the second protrusion 66A1 of the second resistance member 66. Alternatively, during the latch disengagement operation, latch 14 may sequentially contact the first protrusion 64A1 of the first resistance member 64 and the second protrusion 66A1 of the second resistance member 66. Furthermore, alternatively, one of the first resistance member 64 and the second resistance member 66 may be omitted if desired and / or expected. In the illustrated embodiment, the second protrusion 66A1 of the second latch contact member 66A is biased by the second elastic member 66B to rotate toward the pedal shaft 20. That is, the second protrusion 66A1 of the second latch contact member 66A is biased to approach the pedal shaft 20. One arm of the torsion spring of the second elastic member 66B biases the fourth latch fixing member 36, while the other arm biases the second latch contact member 66A. The second locking contact member 66A contacts the second pivot pin 42 and is positioned in the circumferential direction relative to the second support member 62.

[0129] like Figure 5 , Figure 10 and Figure 25 As shown, the bicycle pedal 12 also includes a third resistance member 68. The third resistance member 68 is disposed to the pedal body 22 via a first support member 60. A third locking member 34 is disposed between the first resistance member 64 and the third resistance member 68. Furthermore, a first locking member 24 is disposed between the first resistance member 64 and the third resistance member 68. The third resistance member 68 is configured to apply a third resistance to the locking plate 14 in addition to a third biasing force during a disengagement operation of the locking plate 14 from at least the third locking member 34. Preferably, the third resistance member 68 is configured to apply a third resistance to the locking plate 14 in addition to a third biasing force during a disengagement operation of the locking plate 14 from both the third locking member 34 and the fourth locking member 36. Therefore, the third resistance member 68 increases the disengagement force required to disengage the locking plate 14 from both the third locking member 34 and the fourth locking member 36.

[0130] In addition, such as Figure 25As shown, the third resistance member 68 is configured not to apply a third resistance to the third locking plate fixing member 34. Furthermore, the third resistance member 68 is configured not to apply a third resistance to the fourth locking plate fixing member 36. More specifically, the third resistance member 68 is configured not to apply a third resistance to the locking plate 14 during the engagement operation of the locking plate 14 with the third locking plate fixing member 34 and the fourth locking plate fixing member 36. In other words, the third resistance member 68 is configured such that the engagement force required to engage the locking plate 14 with the third locking plate fixing member 34 and the fourth locking plate fixing member 36 does not increase. In the illustrated embodiment, the third resistance member 68 is spaced apart from the locking plate 14 when the locking plate 14 is fixed to the pedal body 22 by the third locking plate fixing member 34 and the fourth locking plate fixing member 36. Furthermore, the third resistance member 68 is configured to contact the locking plate 14 when the locking plate 14 is twisted during the disengagement operation from the third locking plate fixing member 34 and the fourth locking plate fixing member 36. Alternatively, the third resistance member 68 may be configured to contact the locking piece 14 during engagement, but the third resistance during engagement may be configured to be less than the third resistance during disengagement.

[0131] In the illustrated embodiment, such as Figure 5 , Figure 10 and Figure 25As shown, the third resistance member 68 includes a third locking contact member 68A and a third elastic member 68B. The third locking contact member 68A is configured to contact the locking piece 14 during disengagement from at least the third locking piece retaining member 34 and resist elastic movement of the third elastic member 68B. Preferably, the third locking contact member 68A is configured to contact the locking piece 14 during disengagement from both the third locking piece retaining member 34 and the fourth locking piece retaining member 36 and resist elastic movement of the third elastic member 68B. More specifically, the third locking contact member 68A is configured to contact a second lateral surface of the locking piece 14 during disengagement from both the third locking piece retaining member 34 and the fourth locking piece retaining member 36. In the illustrated embodiment, the third locking contact member 68A includes a third protrusion 68A1, which is arranged in the path of the locking piece 14 when the locking piece 14 is twisted during the disengagement operation. Due to this contact between the locking plate 14 and the third protrusion 68A1, during the disengagement operation of the locking plate 14, the third locking plate contact member 68A resists the elastic movement of the third elastic member 68B. In other words, during the disengagement operation of the locking plate 14, the third protrusion 68A1 resists the elastic movement of the third elastic member 68B. In the illustrated embodiment, the third protrusion 68A1 of the third locking plate contact member 68A is biased by the third elastic member 68B to rotate toward the pedal shaft 20. That is, the third protrusion 68A1 of the third locking plate contact member 68A is biased to approach the pedal shaft 20. One arm of the torsion spring of the third elastic member 68B biases the first locking plate fixing member 24, while the other arm biases the third locking plate contact member 68A. The third locking plate contact member 68A contacts the first pivot pin 40 and is positioned in the circumferential direction relative to the first support member 60.

[0132] In the illustrated embodiment, the third elastic member 68B includes a torsion spring. Here, the third elastic member 68B includes a first biasing member 50. In other words, in the illustrated embodiment, a single torsion spring is used for both the first biasing member 50 and the third elastic member 68B. In the illustrated embodiment, a third locking member 34 is disposed between the third resistance member 68 and the third biasing member 54. Alternatively, a separate torsion spring can be provided for each of the first biasing member 50 and the third elastic member 68B.

[0133] like Figure 5 , Figure 10 and Figure 25As shown, the bicycle pedal 12 also includes a fourth resistance member 70. The fourth resistance member 70 is disposed to the pedal body 22 via a second support member 62. A fourth locking member 36 is disposed between the second resistance member 66 and the fourth resistance member 70. Furthermore, a second locking member 26 is disposed between the second resistance member 66 and the fourth resistance member 70. The fourth resistance member 70 is configured to apply a fourth resistance to the locking piece 14 in addition to a fourth biasing force during the disengagement operation of the locking piece 14 from at least the fourth locking member 36. Preferably, the fourth resistance member 70 is configured to apply a fourth resistance to the locking piece 14 in addition to a fourth biasing force during the disengagement operation of the locking piece 14 from the third locking member 34 and the fourth locking member 36. Therefore, the fourth resistance member 70 increases the disengagement force required to disengage the locking piece 14 from the third locking member 34 and the fourth locking member 36.

[0134] In addition, such as Figure 25 As shown, the fourth resistance member 70 is configured not to apply a fourth resistance to the third locking plate fixing member 34. Furthermore, the fourth resistance member 70 is configured not to apply a fourth resistance to the fourth locking plate fixing member 36. More specifically, the fourth resistance member 70 is configured not to apply a fourth resistance to the locking plate 14 during the engagement operation of the locking plate 14 with the third locking plate fixing member 34 and the fourth locking plate fixing member 36. In other words, the fourth resistance member 70 is configured such that the engagement force required to engage the locking plate 14 with the third locking plate fixing member 34 and the fourth locking plate fixing member 36 does not increase. In the illustrated embodiment, the fourth resistance member 70 is spaced apart from the locking plate 14 when the locking plate 14 is fixed to the pedal body 22 by the third locking plate fixing member 34 and the fourth locking plate fixing member 36. Furthermore, the fourth resistance member 70 is configured to contact the locking plate 14 when the locking plate 14 is twisted during the disengagement operation from the third locking plate fixing member 34 and the fourth locking plate fixing member 36. Alternatively, the fourth resistance member 70 may be configured to contact the locking plate 14 during engagement, but the fourth resistance during engagement may be configured to be less than the fourth resistance during disengagement.

[0135] In the illustrated embodiment, such as Figure 5 , Figure 10 and Figure 25As shown, the fourth resistance member 70 includes a fourth locking plate contact member 70A and a fourth elastic member 70B. The fourth locking plate contact member 70A is configured to contact the locking plate 14 during disengagement from at least the fourth locking plate retaining member 36 and to move against the elastic force of the fourth elastic member 70B. Preferably, the fourth locking plate contact member 70A is configured to contact the locking plate 14 during disengagement from the third locking plate retaining member 34 and the fourth locking plate retaining member 36 and to move against the elastic force of the fourth elastic member 70B. More specifically, the fourth locking plate contact member 70A is configured to contact a first lateral surface of the locking plate 14 during disengagement from the third locking plate retaining member 34 and the fourth locking plate retaining member 36. In the illustrated embodiment, the fourth locking plate contact member 70A includes a fourth protrusion 70A1, which is arranged in the path of the locking plate 14 when the locking plate 14 is twisted during the disengagement operation. Due to this contact between the locking plate 14 and the fourth protrusion 70A1, during the disengagement operation of the locking plate 14, the fourth locking plate contact member 70A resists the elastic movement of the fourth elastic member 70B. In other words, during the disengagement operation of the locking plate 14, the fourth protrusion 70A1 resists the elastic movement of the fourth elastic member 70B. The aforementioned locking plate contact members 64A, 66A, 68A, and 70A can be replaced by the arm portion of a torsion spring. More specifically, the protrusions 64A1, 66A1, 68A1, and 70A1 of the aforementioned locking plate contact members 64A, 66A, 68A, and 70A can be replaced by the arm portion of a torsion spring. That is, the locking plate contact members 64A, 66A, 68A, and 70A can be omitted. In the illustrated embodiment, the fourth protrusion 70A1 of the fourth locking plate contact member 70A is biased by the fourth elastic member 70B to rotate toward the side of the pedal shaft 20. That is, the fourth protrusion 70A1 of the fourth locking contact member 70A is biased to approach the pedal shaft 20. One arm of the torsion spring of the fourth elastic member 70B biases the second locking retaining member 26, while the other arm biases the fourth locking contact member 70A. The fourth locking contact member 70A contacts the second pivot pin 42 and is positioned in the circumferential direction relative to the second support member 62.

[0136] In the illustrated embodiment, the fourth elastic member 70B includes a torsion spring. Here, the fourth elastic member 70B includes the second biasing member 52. In other words, in the illustrated embodiment, a single torsion spring is used for both the second biasing member 52 and the fourth elastic member 70B. In the illustrated embodiment, the fourth locking member 36 is disposed between the fourth resistance member 70 and the fourth biasing member 56. Alternatively, a separate torsion spring can be provided for each of the second biasing member 52 and the fourth elastic member 70B.

[0137] In the illustrated embodiment, such as Figure 25As shown, during the latch disengagement operation, latch 14 simultaneously contacts the third protrusion 68A1 of the third resistance member 68 and the fourth protrusion 70A1 of the fourth resistance member 70. Alternatively, during the latch disengagement operation, latch 14 may sequentially contact the third protrusion 68A1 of the third resistance member 68 and the fourth protrusion 70A1 of the fourth resistance member 70. Furthermore, alternatively, one of the third resistance member 68 and the fourth resistance member 70 may be omitted if desired and / or expected.

[0138] The dual-position cleat 14 will now be discussed in more detail. As mentioned above, the terms "cleat 14" and "dual-position cleat 14" are used interchangeably herein. Essentially, the dual-position cleat 14 is configured to engage the first cleat retaining member 24 and the second cleat retaining member 26 to establish either a first engagement state or a second engagement state based on the wear of the sole of the shoe S. Therefore, depending on whether the cleat 14 is in the first engagement state or the second engagement state, the dual-position cleat 14 is positioned in different locations relative to the pedal body 22.

[0139] Here, the dual-position cleat 14 is a single component made of a rigid material such as metal or fiber-reinforced plastic. Therefore, the shoe attachment 14a, the first dual-position cleat protrusion 14b, and the second dual-position cleat protrusion 14c are integrally formed as a single component. Preferably, the first dual-position cleat protrusion 14b and the second dual-position cleat protrusion 14c extend from opposite ends of the shoe attachment 14a. Furthermore, preferably, the first dual-position cleat protrusion 14b and the second dual-position cleat protrusion 14c are mirror images of each other. Alternatively, the position and shape of the first dual-position cleat protrusion 14b and the second dual-position cleat protrusion 14c of the dual-position cleat 14 can vary depending on the construction of the bicycle pedal. Here, optionally, a two-piece spacer 72 is provided to the dual-position cleat 14. With the dual-position cleat 14 attached to the shoe S, the two-piece spacer 72 is connected to the shoe attachment 14a by a fastener F (see...). Figure 1 The two-piece spacer 72 includes a first portion 72A and a second portion 72B. The two-piece spacer 72 is configured to adjust the orientation of the locking tab 14 relative to the surface of the shoe S. Therefore, each attachment opening 14d is an elongated hole, while the first portion 72A has a pair of circular holes 72A1 and the second portion 72B has a pair of circular holes 72B1, as shown. Figure 33 As shown. When the sole of shoe S wears excessively, causing the bottom surface of the cleat 14 to contact the pedal body 22, the first portion 72A and / or the second portion 72B can maintain the distance between the cleat 14 and the pedal body 22. That is, even if the sole of shoe S wears further, the first portion 72A and / or the second portion 72B can maintain a constant distance between the cleat 14 and the pedal body 22. The first portion 72A and the second portion 72B can be omitted or integrally formed with the cleat 14.

[0140] As described above, the shoe side surface 14a1 of the shoe attachment portion 14a faces the shoe S, while the pedal side surface 14a2 faces the pedal body 22. The shoe attachment portion 14a has a pair of attachment openings 14d. When the clip 14 is secured to the shoe S, each attachment opening 14d receives a fastener F. A reference surface RP2 may be provided between the shoe side surface 14a1 and the pedal side surface 14a2. The reference surface RP2 may be a plane perpendicular to the thickness direction of the clip 14. The reference surface RP2 may be a plane perpendicular to the central axis of the attachment opening 14d through which the fastener F will pass when the clip 14 is secured to the shoe S. Furthermore, the reference surface RP2 may be a plane parallel to the abutting surface of the pedal side surface 14a2 of the clip 14 that abuts against the pedal body 22 when the clip 14 is engaged with the bicycle pedal 12.

[0141] Similarly, in the first configuration, the dual-position locking plate 14 is configured to engage with the third locking plate retaining member 34 and the fourth locking plate retaining member 36 to hold the dual-position locking plate 14 in a third position relative to the pedal body 22. In the second configuration, the dual-position locking plate 14 is configured to engage with the third locking plate retaining member 34 and the fourth locking plate retaining member 36 to hold the dual-position locking plate 14 in a fourth position relative to the pedal body 22. Here, the first and third positions are identical except that the dual-position locking plate 14 is engaged with opposite sides of the pedal body 22. Likewise, the second and fourth positions are identical except that the dual-position locking plate 14 is engaged with opposite sides of the pedal body 22.

[0142] With the bicycle pedal 12 holding the locking plate 14 in place, the first locking plate engagement surface 24a contacts the first locking plate protrusion 14b. With the bicycle pedal holding the locking plate 14 in place, the second locking plate engagement surface 26a contacts the second locking plate protrusion 14c. In this way, the bicycle pedal 12 secures the locking plate 14 to the first side of the pedal body 22. Similarly, with the bicycle pedal holding the locking plate 14 in place, the third locking plate engagement surface 34a contacts the first locking plate protrusion 14b, and the fourth locking plate engagement surface 36a contacts the second locking plate protrusion 14c. In this way, the bicycle pedal 12 secures the locking plate 14 to the second side of the pedal body 22 (i.e., the side opposite to the first side).

[0143] refer to Figure 37 and Figure 39Depending on whether the locking plate 14 is in a first engaged state or a second engaged state, the first locking plate fixing member 24 and the second locking plate fixing member 26 are positioned at different locations relative to the pedal body 22. Specifically, compared to the position of the first locking plate fixing member 24 in the second engaged state, the first locking plate fixing member 24 is displaced on the first pivot pin 40 in a direction away from the rotation center axis R1 in the first engaged state. Similarly, compared to the position of the second locking plate fixing member 26 in the second engaged state, the second locking plate fixing member 26 is displaced on the second pivot pin 42 in a direction away from the rotation center axis R1 in the first engaged state. Depending on whether the locking plate 14 is in a third engaged state or a fourth engaged state, the third locking plate fixing member 34 and the fourth locking plate fixing member 36 are also displaced relative to the pedal body 22 in the same manner.

[0144] The first latching protrusion 14b (also referred to as the first dual-position latching protrusion 14b) has: a first surface portion 14b1 having a first bevel S1, and a first additional surface portion 14b2 having a first additional bevel AS1. The first bevel S1 is different from the first additional bevel AS1. The first surface portion 14b1 is positioned closer to the pedal side surface 14a2 than the first additional surface portion 14b2. The first surface portion 14b1 is positioned closer to the tip of the first latching protrusion 14b than the first additional surface portion 14b2. The first bevel S1 of the first surface portion 14b1 is inclined in a first inclination direction, the first surface portion 14b1 is inclined away from the first additional surface portion 14b2 in the first inclination direction, and approaches the pedal side surface 14a2 as the first surface portion 14b1 extends outward relative to the shoe attachment 14a toward the outer edge of the latch 14. The first additional slope AS1 of the first additional surface portion 14b2 is inclined in the first additional tilt direction. The first additional surface portion 14b2 is inclined away from the shoe side surface 14a1 in the first additional tilt direction and moves toward the first surface portion 14b1 as the first additional surface portion 14b2 extends outward toward the outer edge of the locking plate 14 relative to the shoe attachment portion 14a.

[0145] The second locking plate protrusion 14c (also referred to as the second dual-position locking plate protrusion 14c) includes: a second surface portion 14c1 having a second inclined surface S2, and a second additional surface portion 14c2 having a second additional inclined surface AS2. The second inclined surface S2 is different from the second additional inclined surface AS2. Preferably, the first inclined surface S1 of the first locking plate protrusion 14b is equivalent to the second inclined surface S2 of the second locking plate protrusion 14c. Similarly, preferably, the first additional inclined surface AS1 of the first locking plate protrusion 14b is equivalent to the second additional inclined surface AS2 of the second locking plate protrusion 14c. The second surface portion 14c1 is positioned closer to the pedal side surface 14a2 than the second additional surface portion 14c2. The second surface portion 14c1 is positioned closer to the tip of the second locking plate protrusion 14c than the second additional surface portion 14c2. The second inclined surface S2 of the second surface portion 14c1 is inclined in a second inclined direction. The second surface portion 14c1 is inclined away from the second additional surface portion 14c2 in the second inclined direction and approaches the pedal side surface 14a2 as the second surface portion 14c1 extends outward relative to the shoe attachment portion 14a toward the outer edge of the locking plate 14. The second additional inclined surface AS2 of the second additional surface portion 14c2 is inclined in a second additional inclined direction. The second additional surface portion 14c2 is inclined away from the shoe side surface 14a1 in the second additional inclined direction and approaches the second surface portion 14c1 as the second additional surface portion 14c2 extends outward relative to the shoe attachment portion 14a toward the outer edge of the locking plate 14.

[0146] Therefore, the dual-position locking plate 14 is at least partially configured such that, in a first engagement state where the first locking plate engagement surface 24a engages with the first surface portion 14b1 of the dual-position locking plate 14 when the dual-position locking plate 14 is fixed to the bicycle pedal 12, it is further from the pedal body 22 than in a second engagement state where the first locking plate engagement surface 24a engages with the first additional surface portion 14b2 of the dual-position locking plate 14 when the dual-position locking plate 14 is fixed to the bicycle pedal 12. Similarly, the dual-position locking plate 14 is at least partially configured such that, in a first engagement state where the second locking plate engagement surface 26a engages with the second surface portion 14c1 of the dual-position locking plate 14 when the dual-position locking plate 14 is fixed to the bicycle pedal 12, it is further from the pedal body 22 than in a second engagement state where the second locking plate engagement surface 26a engages with the second additional surface portion 14c2 of the dual-position locking plate 14 when the dual-position locking plate 14 is fixed to the bicycle pedal 12.

[0147] refer to Figures 40 to 42 The engagement of the first locking tab protrusion 14b and the second locking tab protrusion 14c with the first locking tab engagement surface 24a and the second locking tab engagement surface 26a differs in the first engagement state and the second engagement state. Specifically, as... Figure 40As shown, in the first engagement state where the first locking plate engagement surface 24a engages with the first surface portion 14b1, the extension line L1 of the first reaction force vector V1 at the engagement point of the first locking plate engagement surface 24a and the first surface portion 14b1 is located between the rotation center axis R1 and the first pivot axis P1. The position of the extension line L1 of the first reaction force vector V1 relative to the first pivot axis P1 depends on the slope of the first surface portion 14b1. On the other hand, as... Figure 41 and Figure 42 As shown, in the second engagement state where the first locking plate engagement surface 24a engages with the first additional surface portion 14b2, the extension line L2 of the first additional reaction force vector V2 at the engagement point of the first locking plate engagement surface 24a and the first additional surface portion 14b2 lies on the first pivot axis P1 (see...). Figure 42 ), or regarding the first pivot axis P1 being located on the opposite side relative to the rotation center axis R1 (see Figure 41 In other words, in Figure 41 In this configuration, the first pivot axis P1 is located between the extension line L2 of the first additional reaction force vector V2 and the rotation center axis R1. The position of the extension line L2 of the first additional reaction force vector V2 relative to the first pivot axis P1 depends on the slope of the first additional surface portion 14b2.

[0148] In addition, such as Figure 40 As shown, at the first contact point CP1 between the first surface portion 14b1 and the first locking plate engagement surface 24a, which are engaged in a first engagement state, the inclination of the first inclined surface S1 of the first surface portion 14b1 is greater than the inclination of the first tangent TL1 of the first reference circle RC1 centered on the first pivot axis P1 and passing through the first contact point CP1 between the first surface portion 14b1 and the first locking plate engagement surface 24a. The inclination of the first inclined surface S1 and the inclination of the first tangent TL1 are determined relative to the reference surface RP2. Preferably, the inclination of the first inclined surface S1 is within the range of a minimum inclination of 55 degrees and a maximum inclination of 75 degrees. More preferably, the first inclined surface S1 has a maximum inclination of 65 degrees. Even more preferably, as in the illustrated embodiment, the first inclined surface S1 has an inclination of 55 degrees. The inclination angle is an acute angle formed by the reference surface RP2 and the first surface portion 14b1. Similarly, the inclination angle is an acute angle formed by the reference surface RP2 and the first additional surface portion 14b2. In the disclosed embodiments, the angle and slope of the inclined surface are represented by an acute angle relative to a reference plane.

[0149] On the other hand, such as Figure 41 and Figure 42As shown, at the second contact point CP2 between the first additional surface portion 14b2 and the first locking plate engagement surface 24a, which are engaged in the second engagement state, the inclination of the first additional inclined surface AS1 of the first additional surface portion 14b2 is less than or equal to the inclination of the second tangent TL2 of the second reference circle RC2 centered on the first pivot axis P1 and passing through the second contact point CP2 between the first additional surface portion 14b2 and the first locking plate engagement surface 24a. The inclination of the first additional inclined surface AS1 and the inclination of the second tangent TL2 are determined relative to the reference surface RP2. The minimum inclination of the first additional surface portion 14b2 of the dual-position locking plate 14 is the angle of the second tangent TL2 of the second reference circle RC2 when the second contact point CP2 is located at the innermost side of the first additional surface portion 14b2 in the axial direction. The inclination of the first additional surface portion 14b2 of the dual-position locking plate 14 is less than the inclination of the first surface portion 14b1 of the dual-position locking plate 14. Preferably, as Figure 41 In the illustrated embodiment, the inclination of the first additional inclined plane AS1 is 30 degrees.

[0150] refer to Figures 43 to 48 ,replace Figures 28 to 35 The use of the dual-position locking plate 14 allows the bicycle pedal 12 to be interchangeably and releasably fixed to the first locking plate 114. Figures 43 to 45 ) or second locking plate 214 ( Figures 46 to 48 Each of the first and second locking plates 114 and 214 is present. Therefore, the bicycle pedal system includes a first locking plate 114, a second locking plate 214, and a bicycle pedal 12. The bicycle pedal 12 is configured to interchangeably and releasably secure each of the first locking plate 114 and the second locking plate 214. Alternatively, the bicycle pedal 12 is configured to interchangeably and releasably secure each of the dual-position locking plate 14, the first locking plate 114, and the second locking plate 214.

[0151] Basically, the first locking plate 114 is used with the bicycle pedal 12 to establish a third engagement state, while the second locking plate 214 is used with the bicycle pedal 12 to establish a fourth engagement state. The third engagement state is different from the fourth engagement state. More specifically, as described below, the first locking plate 114 is at least partially configured to be further away from the pedal body 22 in the third engagement state compared to the second locking plate 214 in the fourth engagement state.

[0152] In the illustrated embodiment, for ease of understanding, for example, the first locking plate 114 is essentially used with the bicycle pedal 12 to establish the first engagement state of the aforementioned dual-position locking plate 14. In other words, the first engagement state of the dual-position locking plate 14 and the third engagement state of the first locking plate 114 create the same engagement state. On the other hand, in the illustrated embodiment, for ease of understanding, for example, the second locking plate 214 is essentially used with the bicycle pedal 12 to establish the second engagement state of the aforementioned dual-position locking plate 14. In other words, the second engagement state of the dual-position locking plate 14 and the fourth engagement state of the first locking plate 114 create the same engagement state. Therefore, the first locking plate 114 is at least partially configured to be farther from the pedal body 22 in the first engagement state compared to the second locking plate 214 in the second engagement state. That is, the pedal 12 can be suitably engaged with locking plates of different thicknesses. In practice, the engagement state formed by the first locking plate 114 may differ from the first engagement state of the dual-position locking plate 14. Furthermore, alternatively, the engagement state formed by the second locking plate 214 may differ from the second engagement state of the dual-position locking plate 14. That is, the first engagement state of the first locking plate 114 may be different from the first engagement state of the double-position locking plate 14. In addition, the second engagement state of the second locking plate 214 may be different from the second engagement state of the double-position locking plate 14.

The first cleat protrusion 114b has a first surface portion 114b1 with a first bevel S1. Here, the first cleat 114 also includes a second cleat protrusion 114c, which has a second surface portion 114c1 with a second bevel S2. The first bevel S1 of the first cleat protrusion 114b is equivalent to the second bevel S2 of the second cleat protrusion 114c. The first surface portion 114b1 is spaced apart from the first shoe side surface 114a1 by a first distance Y1. The second surface portion 114c1 is also spaced apart from the first shoe side surface 114a1 by a first distance Y1. The first distance Y1 of the first locking plate protrusion 114b can be different from the first distance Y1 of the second locking plate protrusion 114c.

[0154] In the first engaged state where the bicycle pedal 12 secures the first locking plate 114, the first locking plate engagement surface 24a contacts the first surface portion 114b1 of the first locking plate protrusion 114b. Furthermore, in the third engaged state where the bicycle pedal 12 secures the first locking plate 114, the first locking plate engagement surface 24a contacts the first surface portion 114b1 of the first locking plate protrusion 114b. As described above, the first surface portion 14b1 and the first surface portion 114b1 can have the same or different constructions. Therefore, the engaged state where the bicycle pedal 12 secures the first locking plate 114 can be considered either the first engaged state or the third engaged state. In the first engaged state where the bicycle pedal 12 secures the first locking plate 114, the second locking plate engagement surface 26a contacts the second surface portion 114c1 of the second locking plate protrusion 114c. Furthermore, in the third engaged state where the bicycle pedal 12 secures the first locking plate 114, the second locking plate engagement surface 26a contacts the second surface portion 114c1 of the second locking plate protrusion 114c. As described above, the second surface portion 14c1 and the second surface portion 114c1 can have the same or different structures. Figure 40 Similar to the description in the text, in the engaged state where the first locking plate engagement surface 24a engages with the first surface portion 114b1, the extension line of the reaction force vector at the engagement point of the first locking plate engagement surface 24a and the first surface portion 114b1 lies between the rotation center axis R1 and the first pivot axis P1. The second surface portion 114c1 of the second locking plate protrusion 114c may also have a structure corresponding to the first surface portion 114b1 of the first locking plate protrusion 114b.

[0155] refer to Figures 46 to 48 The second cleat 214 will now be discussed. The second cleat 214 includes a second shoe attachment portion 214a and a third cleat protrusion 214b. The second shoe attachment portion 214a has a second shoe side surface 214a1 and a second pedal side surface 214a2. The third cleat protrusion 214b has a third surface portion 214b1 with a third bevel S3. The third surface portion 214b1 is spaced apart from the second shoe side surface 214a1 by a second distance Y2. The second distance Y2 is different from the first distance Y1. The second cleat 214 also includes a fourth cleat protrusion 214c, which has a fourth surface portion 214c1 with a fourth bevel S4. The third bevel S3 of the third cleat protrusion 214b is equivalent to the fourth bevel S4 of the fourth cleat protrusion 214c. The fourth surface portion 214c1 is spaced apart from the second shoe side surface 214a1 by the second distance Y2. The second distance Y2 of the third locking plate protrusion 214b can be different from the second distance Y2 of the fourth locking plate protrusion 214c. Similar to... Figure 41 and Figure 42As described, in the engaged state where the first locking plate engagement surface 24a and the third surface portion 214b1 are engaged, the extension line of the reaction force vector at the engagement point of the first locking plate engagement surface 24a and the third surface portion 214b1 lies on the first pivot axis P1, or on the opposite side of the rotation center axis R1 with respect to the first pivot axis P1. The fourth surface portion 214c1 of the fourth locking plate protrusion 214c may also have a structure corresponding to the third surface portion 214b1 of the third locking plate protrusion 214b.

[0156] In the fourth engaged state where the bicycle pedal 12 secures the second locking plate 214, the first locking plate engagement surface 24a contacts the third surface portion 214b1 of the third locking plate protrusion 214b of the second locking plate 214. In the second engaged state where the bicycle pedal 12 secures the second locking plate 214, the first locking plate engagement surface 24a contacts the third surface portion 214b1 of the third locking plate protrusion 214b. In the second engaged state where the bicycle pedal 12 secures the second locking plate 214, the second locking plate engagement surface 26a contacts the fourth surface portion 214c1 of the fourth locking plate protrusion 214c. As described above, the first additional surface portion 14b2 and the third surface portion 214b1 may have the same or different structures. As described above, the second additional surface portion 14c2 and the fourth surface portion 214c1 may have the same or different structures.
