Locking the pedals provided by the pedals*, the thin pedals can be formed on the pedal body, so that the material cost can be greatly reduced and the overall weight can be reduced to achieve a lighter weight. Increase the tread surface below the tread plate and the ground _distance' so that the over-bending limbs during riding can be improved, so that the corner riding will become more flexible and smooth. [Embodiment] As shown in FIGS. 2 to 5, the present invention provides a preferred embodiment of a bicycle thin pedal. The thin pedal 1 mainly includes a pedal body 3A, a joint 4A, and a locking member 50. The following description is made for the above constituent members. The pedal body 30 has a stepping sheet 31 and a pivoting shaft 32 integrally formed at the end of the stepping sheet 31; the stepping sheet 31 has an opposite stepping surface 311 and a stepping surface 312, and the upper and lower portions A plurality of hollow holes 313 of different sizes are disposed between the tread surfaces 311 and 312, so as to reduce the weight of the tread sheet 31, and the tread sheet 31 of the present embodiment is approximately between 2 and 2, so that the whole is thin. . The pivoting shaft 32 mainly extends from the pivoting shaft 32 and the stepping plate 201217221 3 . 1 to the outer side direction mainly has a three-stage cylindrical cylindrical surface having a diameter from large to small, including a first pivoting section 321 and a through-and-out The segment 322 and the second pivoting segment 323 have a cylindrical shape, so that the first pivoting portion 321 is engaged with the lower treading plate 31 on the thin treading plate 31. The vertical wall surface 324 can be formed naturally; in particular, in order to avoid stress concentration at the junction of the vertical wall surface 324 and the upper and lower tread surfaces 311, 312, a curved surface 325 can be designed at the joint. As shown in Figure 6; of course. A plurality of connecting ribs 326, as shown in Fig. 7, can also be used to increase the structural strength here; the pivoting shaft 32 is further provided with a screw hole 327 at the end of the second pivoting section 323. The joint 40 includes a joint body 41, a first bearing 42, and two second bearings 43. The joint body 41 is substantially tubular in shape and has a larger official diameter portion 411 and a smaller outer portion. a diameter portion 412; the small diameter portion 412 is formed with a section of external thread 413, which can be screwed together with the crank (five) end hole; the joint body 41 has a first chamber 414 inside, A second chamber 415' and a through hole 416 extending through the first chamber 414 and the second chamber 415. The first bearing 42' can be mounted in the first chamber 414 of the joint body 41 and can be pivotally coupled to the first pivot portion 321 of the pedal body 3's pivotal shaft. The first bearing 42 of this embodiment employs a ball bearing of a south load strength. The second bearings 43' can be mounted side by side in the second chamber 415 of the joint body 4!, and can be used to mutually penetrate the second pivot portion 323 of the pedal body 3 pivotally 5 201217221 32. Set of docking. The second bearing 43 of this embodiment is also a ball bearing having a high load strength. As can be seen from the above, when the joint 40 and the pedal body 30 are assembled with each other, the pedal body 3 is coupled to the extending portion 322 of the shaft 32 between the first and second wire segments 321 and 323. The joint 40 is located in the perforation between the first and second chambers 414, 415. The locking element 44' is in the form of a locking screw, and can be screwed to the screw hole 327 of the end of the shaft 32 of the body 30, so that the second bearing near the crank 60 side is fixed. The inner ring wall 43 can be axially abutted and the joint 40 is securely assembled with the pedal body 30. When the thin pedal 1 of the present invention is assembled, the pivot shaft of the pedal body 3〇 can be penetrated from the inside of the first bearing 42 of the joint 40, and after the through hole 416 and the second bearing 43 are passed, the above locking is performed. The element 44 and the screw hole 327 at the end of the pivot shaft 32 are screwed together to complete the grouping operation of the thin pedal. Therefore, when the thin pedal 1 and the crank 60 are assembled to each other, the external pedal 413 on the joint 40 can be screwed into the screw hole of the crank 6〇, and the thin pedal 1 and the crank can be quickly completed. 6〇 assembly work. The first bearing 42 and the second bearing 43 are disposed on the joint 4 of the above preferred embodiment of the present invention. However, not limited thereto, two first bearings 42 or two second bearings 43 may be disposed. In principle, the structure of the present invention can be applied to the structure of the present invention as long as the bearing bearing strength is sufficient to withstand the load transmitted by the pedal body 3 when it is stepped on, without being limited in number. After the pedal body 30 and the joint 4 of the above-described preferred embodiment of the present invention are threaded, the locking member 44, which can be a locking bolt, and the screw hole 327 of the end portion of the pedal body pivoting shaft 32 are screwed and locked with each other. , which is firmly set to each other's [S} 6 201217221, but not limited thereto, the external peripheral wall of the end of the pivot shaft 32 may be provided with an external thread 'and the above-mentioned locking element 44 is designed For the purpose of locking the nut, the two can be screwed together with the external threads on the outer peripheral wall of the pivoting shaft 32 by the tightening bolts to achieve the same firm assembly effect. The thin pedal 1 of the present invention is provided with a small number of pivot shafts 32 at one end of the pedal body 30 for providing any penetrating mandrel ′ for use with the boring head 40.轴承The women's bearings are pivotally connected to each other to form the pedal body 3〇φ & the pivoting structure required for stepping on, so that the pedal body 3〇 can be designed to be ultra-imaginally thin and thin plate-like structure. That is to say, the above-mentioned room; therefore, the use of the material or its cost can be greatly reduced, and the overall weight can be greatly reduced, and the demand for weight reduction can be achieved. The pedal body 30 of the present invention does not need to provide a mandrel through-mounting. Therefore, the above-mentioned various shapes and unequal-sized hollow holes 313' can be further provided on the pedaling plate 31 to allow the overall weight to be further reduced, and is required. Worried about the problem of mandrel installation and exposure. As described above, since the thickness of the stepping sheet 31 of the pedal body 30 of the present invention can be greatly reduced, the distance between the tread surface 312 of the pedaling sheet 31 and the ground can be increased, so that the bicycle can be increased. The cornering angle at the time of riding makes the turning ride more flexible and smooth. According to the above description, the present invention has excellent advancement and practicability in the same kind of products. The same technical and literature on such structures have been investigated in the same place, and no identical structure exists in the first place. The invention has already possessed the invention patent requirements, and Ling applied for it according to law. However, the above description is only a preferred embodiment of the present invention, and therefore, it is intended that the application of the present specification and the patent application of the invention are included in the scope of the present invention.
