Description

Technical field

[0001] The invention relates to a pedal, in particular a clipless pedal. State of the art

[0002] A bicycle's clipless pedal uses a fixed and a movable clamping element, positioned opposite each other on the pedal, to connect a cleat to the bottom of the cyclist's shoe, thus keeping the rider's feet attached to the pedal. This makes pedaling easier and acceleration faster than with pedals without a clipless mechanism. Therefore, clipless pedals are commonly used on mountain bikes, off-road bikes, road bikes, and other types of bicycles.

[0003] In general, the movable clamping element can adjust the clamping force for the cleat via a preload mechanism, as known, for example, in TWI474949 and TW503201. However, in such conventional clipless pedals, the preload mechanism is located directly on the pedal body. Therefore, assembly and disassembly, maintenance, and replacement are not easy, especially for average users.

[0004] For this reason, it is necessary to provide a novel and advanced pedal to solve the aforementioned problems. Object of the invention

[0005] The object of the invention is to provide a clamping assembly for a click pedal that can be easily assembled and disassembled, replaced and maintained.

[0006] This objective is achieved by the clamping assembly of a clipless pedal according to the invention, which comprises: a pedal body having a mounting surface and a first shoulder section facing away from the mounting surface; a first clamping element having a transverse section detachably attached to the mounting surface and a longitudinal section extending transversely from the transverse section, the longitudinal section forming a second shoulder section which abuts the first shoulder section; a second clamping element; an axle connecting the longitudinal section and the second clamping element so that the second clamping element can rotate relative to the first clamping element; and a preloading mechanism located between the first clamping element and the second clamping element, which preloads the second clamping element.

Detailed description of preferred embodiments

[0007] The following embodiments serve only to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

[0008] Fig.Figures 1 to 6 show an embodiment of the present invention. The pedal 1 of the present invention comprises a pedal body 10, a first clamping element 20, a second clamping element 30, an axle 40 and a preloading mechanism 50.

[0009] The pedal body 10 has a mounting surface 11 and a first shoulder section 12 facing away from the mounting surface 11. The first clamping element 20 has a transverse section 21, which is detachably attached to the mounting surface 11, and a longitudinal section 22, which extends transversely from the transverse section 21. The longitudinal section 22 forms a second shoulder section 221, which rests against the first shoulder section 12. The axle 40 connects the longitudinal section 22 and the second clamping element 30, allowing the second clamping element 30 to rotate relative to the first clamping element 20. The preloading mechanism 50 is located between the first clamping element 20 and the second clamping element 30 and preloads the second clamping element 30.A salesperson, maintenance personnel, or general user simply needs to detach the first clamping element 20 from the pedal body 10, allowing the first clamping element 20, the second clamping element 30, and the preload mechanism 50 to be easily and conveniently installed, removed, or replaced. A first clamping element 20 and a second clamping element 30 can be provided at each of two opposite ends of the pedal body 10. The first clamping element 20 and the second clamping element 30, located on the same side of the pedal body 10, can clamp the cleat of the shoe between them.

[0010] Preferably, the first shoulder section 12 and the second shoulder section 221 are arranged parallel to the mounting surface 11. The first clamping element 20 uses the second shoulder section 221 to slide along the first shoulder section 12 into the pedal body 10. A portion of the pedal body 10 is clamped between the transverse section 21 and the second shoulder section 221 to facilitate the installation of the first clamping element 20, ensuring that the first clamping element 20 is effectively, stably, and reliably secured. The pedal body 10 also has two projections 13. Each projection 13 is provided with a connection structure 131 (e.g., a screw hole). The first shoulder section 12 has two first shoulder surfaces 121. On two opposite sides of each projection 13, a first shoulder surface 121 and a connection structure 131 are formed. The transverse section 21 has two mounting lugs 211.Each mounting eyelet 211 is detachably attached to a connecting structure 131 (e.g., screwed in place by a screw 60) to facilitate assembly, disassembly, replacement, and maintenance. The transverse section 21 also has two tabs 212. The two tabs 212 project radially from the two mounting eyelets 211 and are connected to the longitudinal section 22, thereby increasing the structural strength of the transverse section 21 and ensuring a reliable connection.

[0011] In this embodiment, the longitudinal section 22 also has two first extension sections 222 extending from the cross-section 21, and two second extension sections 223. The second shoulder section 221 is connected transversely between the two first extension sections 222 and the two second extension sections 223. The axis 40 runs through the two second extension sections 223. Specifically, the second shoulder section 221 is connected vertically to the second extension sections 223, and a space 224 is formed between them. The second clamping element 30 has two hinge lugs 31. The hinge lugs 31 are accommodated in the spaces 224, which reduces the overall thickness and contributes to the stable movement of the longitudinal section 22.

[0012] Preferably, a connecting section 23 is joined between the transverse section 21 and the longitudinal section 22. The connecting section 23 is perpendicular to the transverse section 21 and the longitudinal section 22. The connecting section 23 rests against a side wall of the pedal body 10 adjacent to the mounting surface 11, thereby increasing the contact area and the stability of the first clamping element 20 and the pedal body 10, and strengthening the connection between the transverse section 21 and the longitudinal section 22. The second clamping element 30 can form an extension arm 32 in one piece. The extension arm 32 extends in the same direction as the longitudinal section 22 and is located between the two pivot eyes 31, which can improve the connection strength and the rotational stability of the second clamping element 30.

[0013] The pedal body 10 also has a recess 14. The axle 40 moves freely through the longitudinal section 22 and the second clamping element 30. The axle 40 is blocked by two opposing side walls of the recess 14, so that the longitudinal section 22 and the second clamping element 30 cannot be separated from the axle 40. That is, the axle 40 is not inserted into the pedal body 10 and is detachably assembled with the first clamping element 20, the second clamping element 30, and other components. When the first clamping element 20 is removed from the pedal body 10, all components can be easily and conveniently assembled, disassembled, or replaced.

[0014] In this embodiment, the preloading mechanism 50 comprises at least one elastic element 51, which is inserted onto the axle 40, a screw element 52, which is movably arranged on the second clamping element 30, and a pressure element 53, which is inserted onto the screw element 52. One end of the at least one elastic element 51 rests against the pressure element 53, and the other end rests against the connecting section 23 (which may also rest against the pedal body 10). By rotating the screw element 52, the pressure element 53 can be moved to adjust the preload of the at least one elastic element 51 and thus change the clamping force of the second clamping element 30. When the at least one elastic element 51 is not under load, a side surface of its other end is in flat contact with the bottom surface of the recess 14.
