Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bicycle pedal for bicycle racing, and aims to facilitate the operation of attaching and detaching the foot to the pedal, and to ensure that the foot is securely held.

Hereinafter, the present invention will be explained based on illustrative embodiments.

In the drawings, 1 is a pedal shaft, 2 is a pedal bearing body, which includes a shaft insertion part 3 through which the pedal shaft 1 is rotatably inserted, and a front projection part 4 having a circular planar shape and integrally extending forward from the shaft insertion part 3.
, and a rear protrusion 5 extending rearward integrally, the shaft insertion part 3, front protrusion 4, and rear protrusion 5 all have the same flat upper surface connected to the road surface. 6, and the lower part 4a of the front protrusion 4 is formed into a streamlined cross section that gradually becomes thinner from the shaft insertion part 3 to the tip in order to reduce air resistance.

A ball 7 is housed inside the pedal shaft insertion portion 3, and a ball pusher 8 is provided at the shaft end of the pedal shaft 1 that protrudes to one side of the pedal shaft insertion portion 3.
is inserted, and the lock nut 9 is tightened.

These balls 8 and lock nuts 9 are left exposed without being covered with the cap 10 shown by the imaginary line in FIG. 1, so that tools can be easily hung on them and the ball contact adjustment work can be made easier. .

Reference numeral 11 designates a shoe stopper that protrudes from the upper surface 6 side of the front projection 4 of the pedal bearing body 2, and includes a shaft portion 12 that projects upward from the upper surface 6, and a flange 13 that extends from the upper end of this shaft portion 12. It is formed in a T-shaped cross section.

This shoe stopper 11 is for engaging and disengaging a front locking device 17 fixed to the front side of the sole 15 of a shoe 14 (the right shoe is shown in the example shown) as shown in FIG. 6 with a screw 16 or the like. be.

A vertical groove 18 with a T-shaped cross section is formed in the front-rear direction in the front locking device 17 so as to be able to engage and disengage the shoe stopper 11, and the front end 18a of the vertical groove 18 is such that the shoe stopper 11 can be easily inserted into the front end 18a of the vertical groove 18. The front part is slanted open.

Reference numeral 19 denotes a rear plate formed into a three-dimensional planar shape, which includes a shoe sole receiving plate part 20 and a strap attachment piece 22 having a strap passage hole 21 formed by bending both ends of this plate part 20 to the same side. The shoe sole support plate 20 stands up from the upper surface 6 of the rear projection 5 of the pedal bearing body 2 and is fixed to the rear projection 5 with screws 23' so as to be parallel to the pedal shaft 1. .

This rear plate 19 is a shoe sole 15 as shown in the sixth figure.
It is attached to and detached from a rear locking tool 23 fixed to the rear side with screws, etc., and the rear locking tool 23 has a horizontal groove in which the shoe sole receiving plate part 20 of the rear plate 19 is engaged and released in the vertical direction. 24 is formed to be located parallel to the pedal shaft 1.

Further, a strap 25 is attached to the strap attachment piece 22 facing forward from both ends of the shoe sole receiving plate portion 20 of the rear plate 19 by passing through the strap passage hole 21.

In the above configuration, in order to attach the shoe 14 on the pedal bearing body 2, first insert the open front end 18a of the vertical groove 18 of the front stopper 17 of the shoe sole 15 into the shoe stopper 11 on the pedal side. If you slide it from the rear to the front and push it in, the flange 13 of the shoe stopper 11 will fit into the longitudinal groove 18 of the front locking device 17, and the locking device 17 will be pulled out above the shoe stopper 11. It is engaged without any problem.

After this attachment, place the shoe sole 15 on the shoe sole receiving plate 20 of the rear plate 19 on the pedal side, and then
When the lateral groove 24 of No. 3 is fitted, the shoe 14 is engaged so that it will not slide forward or backward on the upper surface 6 of the pedal bearing body 2.

Finally, by tightening the strap 25 over the shoe 14, the rear locking device 23 is fixed so that it will not come out above the shoe sole support plate 20, and the entire fuse 14 is attached to the upper surface of the pedal bearing body 2. 6, it can be stably and securely fixed in place.

From the wearing state of the shoes 14, this is the pedal bearing body 2.
To remove the shoes from the rear plate 19, simply reverse the above-mentioned installation order. That is, first unfasten the strap 25, then pull up the rear side of the shoe sole 15 slightly upwards, and the shoe sole holder of the rear plate 19 will be removed. The groove engagement of the rear locking tool 23 can be disengaged from the plate portion 20, and the shoe 1
4 to the rear, the shoe stopper 11 can be pulled out from the front locking device 17.

According to the present invention, when attaching the pedals and shoes 14,
The shoe sole 15 can be fitted into the lateral groove 24 simply by engaging the front stopper 17 and the stopper 11 by moving the shoe 14 forward and then placing the shoe sole 15 on the upper surface 6. Since it is only necessary to tighten the shoe sole 15, which cannot be seen by the bicycle rider, the sole 15 of the shoe can be securely secured at once.

To remove the pedals and shoes 14, once the straps are unfastened, the shoe sole receiving plate 20 can be removed from the lateral groove 24 by simply pulling up the rear side of the shoe sole 15 a little, and then the shoe 14 can be removed. Since it is only necessary to pull the shoe sole 15 backward, engagement with the sole 15 of the shoe, which cannot be seen by the bicycle rider, can be reliably performed in one go.

Moreover, since the release of the attachment is reliably performed, no force is applied to the front and rear locking devices 17.23 to peel them off from the shoe sole 15, and damage to the front and rear locking devices 17, 23 can be prevented.

When the Yota shoes 14 and the pedals are attached, the lateral grooves 24 and the shoe sole receiving plate 20 are both parallel to the pedal axis 1, so the shoes 14 do not move in the front-rear direction, and the T
Shoe stopper 11 with shaped cross section and T of front fastener 17
Since the vertical grooves 18 of the shaped cross section are engaged and tightened by the straps 25, there is no possibility of vertical movement.

Moreover, the shoes 14 are connected to the stopper 11 and the front fastener 1.
Even if an attempt is made to rotate the shoe 14 around the engaging portion 7, the rotation is blocked because the lateral groove 24 and the shoe sole receiving plate 20 are both located parallel to the pedal axis 1, and the shoe 14 is prevented from moving in the left-right direction. The shoe 14 can be securely fixed to the pedal without moving.
