Abstract

PURPOSE: A pedal for a bicycle and a bicycle type exercise machine is provided to ensure stable coupling between footholds and shafts and simplified assembly. CONSTITUTION: A bicycle comprises a foothold(1a) with a shaft insertion hole and a stop ring insertion hole(12), a shaft(2a) with a stop ring groove(13), and a stop ring(3). The shaft is inserted in the shaft insertion hole of the foothold and the stop ring is inserted in the stop ring groove through the stop ring insertion hole so that the foothold and the shaft are coupled together. Needle roller bearings are inserted to both sides of the shaft insertion hole of the foothold before insertion of the shaft.

Description

PEDAL OF BICYCLE AND BICYCLE TYPE EXERCISING MACHINE}

The present invention relates to a pedal of a bicycle and a bicycle-type exercise equipment, by combining the footrest and the shaft with a stop ring to stabilize the coupling state between the components and simplify the assembly process, in the shaft insertion hole of the footrest, between the footrest and the shaft By providing a lubricant storage space in the lubricant characterized in that it is possible to continuously supply the lubricant to the friction portion between the parts.

Generally, a pedal of a bicycle and a bicycle type exercise machine is constituted such that a shaft is inserted from one end to the shaft insertion hole penetrating from one end of the foot plate to the other end, the washer is fitted to the end of the shaft from the other side, To fix the washer, or engage the foot and shaft by tightening the washer and nut or only the nut at the end of the shaft with male thread. A ball bearing is also used between the pedal foot and the shaft.

Technical Challenge

Insert the shaft from one end into the shaft insertion hole that penetrated from one end to the other end, and from the other side, put the washer at the end of the shaft and hit the end of the shaft to open the end of the shaft so that the washer is fixed. In this case, when the end of the shaft is bent, the foot may be bent and the foot may not turn well.In the case where the foot and the shaft are combined with a washer and a nut or only with a nut at the end of the shaft, the foot may not turn well depending on the tightness of the nut. It can be too loose and loose. Either way, the pedal's foot and shaft are unstable and the assembly process is complicated. In addition, the use of ball bearings between the scaffold and the shaft makes the scaffold thick, and if the pedal is exposed to the natural environment for a long time, the friction between the parts may lack lubricant.

Challenge solution

In order to solve this problem, the present invention combines the footrest 1a and the shaft 2a with the stop ring 3 or the footrest 1b and the shaft 2b having the needle roller bearings 4 inserted into both of the shaft insertion holes 11b. Engage with the stop ring (3). The spaces 21a and 21b for storing the lubricant to be continuously supplied to the friction portions between the respective components are inserted into the shaft insertion holes 11a and 11b of the foot plates 1a and 1b and between the foot plates 1a and 1b and the shafts 2a and 2b, 2b).

Effects of the Invention

As a result, the present invention makes the coupling state of the footrests 1a and 1b and the shafts 2a and 2b more stable, simplifies the assembly process, and is more effective than using a ball bearing between the footrests 1b and the shafts 2b. It is possible to make the footrest 1b thin, and to continuously supply lubricant to the friction part between the parts.

Best Mode for Carrying Out the Invention

On the basis of the accompanying drawings will be described in detail an embodiment of the present invention

As shown in FIGS. 1 and 2, the shaft 1a with the shaft insertion hole 11a and the stop ring insertion hole 12, the shaft 2a with the stop ring groove 13, and the stop ring 3 are provided. The shaft 2a is inserted into the shaft insertion opening 11a of the footrest 1a and the stop ring 3 is inserted into the stop ring groove 13 of the shaft 2a through the stop ring insertion opening 12 of the footrest 1a. To reach) to engage the footrest 1a and the shaft 2a, or

As shown in FIGS. 3 and 4, the footrest 1b with the shaft insertion hole 11b and the stop ring insertion hole 12, the shaft 2b with the stop ring groove 13, and the two needle roller bearings ( 4), the stop ring (3) and the stopper (5), each of the needle roller bearing (4) is inserted into both sides of the shaft insertion opening (11b) of the footrest (1b) and then insert the shaft (2b), stop ring (3) is inserted into the stop ring groove (13) of the shaft (2b) through the stop ring insertion opening (12) of the footrest (1b) to engage the footrest (1b) and the shaft (2b) and the stopper (5) Complete by blocking.

This stabilizes the mating of the parts and simplifies the assembly process.

2 and 4, the lubricant storage spaces 21a and 21b in the shaft insertion openings 11a and 11b of the scaffolds 1a and 1b and between the scaffolds 1a and 1b and the shafts 2a and 2b. So that the lubricant can be continuously supplied to the friction area between the parts.

When assembling as shown to FIG. 3 and FIG. 4, the board | substrate 1b is made up-down left-right symmetrical so that the shaft 2b may be inserted in either of the shaft insertion opening 11b of the footboard 1b.
