Problems solved by technology

[0009] In the above invention, the stopper collar (stopper collar) is biased toward the crank side by the spring. In this state, although the locking body is maintained in the state locked on the pedal shaft, the , since the limit of movement of the stopper collar towards the pedal side is only dependent on the spring, it is possible for the stopper collar to move towards the pedal side when an unexpected force is generated that has not been considered, As a result, the pedals may fall off

Embodiment Construction

[0031] Such as figure 1 ~As shown in FIG. 6 , on the pedal shaft 1 of the pedal A, a locking concave portion 2 is formed in a ring shape, and the locking concave portion 2 is detachably connected with the receiving member 4 fixed on the pedal crank 3 . Locking, thereby fixing the pedal A on the pedal crank 3.

[0032] The specific structure of the locking body is as follows.

[0033] The top end of the above-mentioned pedal crank 3 is provided with a mounting hole for pedal shaft installation, and a threaded groove is provided on the inner wall of the mounting hole. The threaded collar 5 is screwed into the threaded groove 5a provided on it to install the threaded collar 5.

[0034] On the peripheral wall of the threaded collar 5, four through-holes 7 for mounting the locking bodies 6 are formed at equal intervals on the same circumference, and the locking bodies 6 as spherical bodies are respectively installed in these through-holes 7 .

[0035] A stopper collar 8 is attac...

Abstract

The invention provides a foot pedal mounting device for a bicycle. The device for mounting a foot pedal shaft can be mounted and dismounted freely and cannot make the foot pedal fall off due to the neglected force. The foot pedal mounting device consists of a coupling piece assembled in a foot pedal shaft mounting hole on a foot pedal crank and the foot pedal shaft provided with a stopping recessfor stopping a stopping body on the periphery. The coupling piece consists of a thread shaft collar of which the inside diameter has the same shape as that of the foot pedal shaft, the stopping body mounted in a through hole formed on the thread shaft collar, and a stop dog shaft collar mounted on the outer side of the thread shaft collar in a sliding mode. A spring is arranged between the threadshaft collar and the stop dog shaft collar; and when a bulge arranged on the thread shaft collar is aligned with a position on a groove formed on the stop dog shaft collar, the stop dog shaft collar is slid to release the stopping of the stopping body and the stopping recess.

Description

technical field [0001] The present invention relates to a mounting device for bicycle pedals. Background technique [0002] In conventional bicycle pedals, threads are provided on a pedal shaft and a pedal crank (pedal crank), and they are fixed by screwing them together. [0003] This configuration makes pedal installation impossible for persons without bicycle maintenance skills. However, in recent years, although the sales channel of bicycles has shifted to mass merchandisers other than bicycle specialty stores, such technicians are not required for mass merchandisers. In addition, it is expected that ordinary consumers who do not have the technology can ship the pedals with the pedals removed (disassembled) and install the pedals by themselves even by mail order (or online shopping). [0004] Also, for cyclists, pedals are sometimes exchanged depending on the conditions of use. However, tools and time are required for attachment and detachment of the known footrests, ...
