Description

[Detailed Description of the Invention] The present invention relates to a bicycle pedal used mainly for competitive bicycles such as road races, bicycles for sports such as cars, or cycling.

Generally, a pedal such as a racing bicycle is equipped with a toe clip having a toe strap, and by inserting a shoe into the toe clip and tightening the toe strap, the shoe is integrally fixed to the pedal, It applies rotational force to the crank not only when the pedal is depressed, but also when the pedal is pulled up, making the bicycle run at high speed.
Since the shoes are fastened to the pedals by the toe straps, there is a problem in that when the bicycle falls, the shoes cannot be quickly released from the pedals, leading to unexpected accidents such as injuries to the ankles and the like.

□ ・In order to prevent the above-mentioned accident, wide tightening bands are attached to both the left and right sides of the pedal body to serve as toe clips and toe straps, and the tightening bands are The middle part is separated and a locking device, such as a hooking fastener called Velcro, that can be removed with a certain amount of input is attached to each end of the band, and the shoe is fixed by attaching and detaching the locking device. and removing the shoes in the event of a fall.

A device that prevents accidents has already been proposed, but in this case, the locking device can be released in the event of a fall, so when the pedal is depressed or pulled up, a rotational force exceeding a specified level is applied to the locking device. If the locking device is attached to the pedal, there is a risk that the locking device may loosen or come off, and the rotational force may not be sufficiently obtained. The locking devices had to be attached and detached each time, resulting in poor operability.

The present invention was devised by focusing on the above-mentioned problems, and it not only simplifies the operation of attaching and detaching shoes to and from the pedals, but also strengthens the holding force of the shoes when pressing the pedals. Moreover, it is an object of the present invention to provide a pedal for a bicycle, which allows shoes to be quickly removed from the pedals when the bicycle falls down, thereby preventing unexpected accidents.

Specifically, a holder is formed of a locking body that extends in the front-rear direction of the pedal body and has a depression surface, and a pair of scripts extending from both sides of the locking body in the left-right direction of the pedal body. A holder is attached to both sides of the pedal body in the left-right direction so that the locking body is displaced in the front-rear direction of the pedal body and in a direction approaching the stepping surface, and the holding device is inserted into the pedal by the displacement of the locking body. The shoe is characterized in that it strengthens the holding power of worn shoes and allows quick removal of the shoes.

Hereinafter, embodiments of the present invention will be described based on the drawings.

1 is a front part centered on the pedal shaft 2, an axially-side surface, and a rear part, an axially other side surface, and a stepping surface 1a, lb, lc at the rear.
3 is a holder attached to the pedal body 1, and a locking body 4 facing the front and rear of the pedal body 1;
A pair of scripts 5 and 6 extend from both sides of the locking body 4 in the left-right direction of the pedal body 1.

The holder 3 shown in the figure is made of a synthetic resin material having rigidity and is integrally formed.As shown in FIGS. m) A pair of narrow and thin (approximately 2 m/m) legs 5 and 6 are attached from the rear of the intermediate portion of the locking body 4 and both side walls of the locking body 4,
The distal ends of the legs 5, 6 are extended so as to be located at the rear, and leg pieces 8, 9 are provided at the distal ends of the legs 5, 6, and the pedal body is attached to these leg pieces 8, 9. Mounting hole 10 to 1
．． 10 is bored, and the center position of the locking body 4 is located forward of the center line of the mounting hole 10.10.

The wall thickness of the scripts 5 and 6 may be the same over the entire length, but preferably the leg pieces 8 and 9 are thicker (approximately 5 m/m) as shown in FIG. ) to increase the mounting strength.

Then, the holder 3 constructed as described above is shown in FIGS. 1 to 4.
As shown in the figure, in order to attach the locking body 4 to both sides of the pedal body 1 in the left-right direction, the locking body 4 is arranged so that its length direction faces the front-rear direction of the pedal body 1, and screws 11 and 11 The locking body 4 is pivotally connected to the pedal body 1 in the front-rear direction, and the tread surface 1 a?
1 b * 1 c so that they are displaced toward and away from each other.

Furthermore, in order to attach the holder 3 using the screw 11 as described above, as shown in FIG.
into the mounting holes 10, 10 of the screws 1.1. jl
This is done by screwing into screw holes 12 provided on both sides of the pedal body 1 in the left and right direction.

As shown in FIG. 3, the holder 3 attached to the pedal body 1 has an inverted U-shape due to the elasticity of the legs 5.6, and the locking body 4 is attached to the pedal body 1. The shoe is positioned above the stepping surface 1awlbw1c with a gap through which the shoe can be inserted.

The present invention is constructed as described above, and when a shoe is inserted between the stepping surfaces 1a to 1c of the pedal body 1 and the locking body 4 of the holder 3, as shown in FIG. swings forward as the shoe is inserted, and the legs 5, 5 and the locking body 4
is displaced in the forward direction of the pedal body 1, as shown by the two-dot chain line in FIG.
The shoes placed on top are pressed downward from above and held.

That is, since the locking body 4 moves circularly via the legs 5 and 6 when the shoe is inserted, the distance between the locking body 4 and the stepping surface side is narrowed, and the locking body 4 is held on the shoe placed on the stepping surface 1aib. A force is applied, which ensures that the shoe is held in place.

Furthermore, when the shoe inserted into the pedal body 1 is pulled out to the rear, the holder 3 swings in the opposite direction to the swinging force direction described above, so that the distance between the shoe and the locking body 4 of the holder 3 is increased. It spreads out, loses its grip on the shoe, and can be easily removed.

Therefore, even if the bicycle falls down, the shoes can be quickly removed from the pedal body 1, and unexpected accidents can be prevented.

In the above embodiment, when attaching the holder 3 to the pedal body 1, the screw holes 12 are provided on both sides in the left and right direction behind the center of the pedal body 1, and the leg pieces 8 and 9 are attached to the pedal body. It is preferable to install it so that it is positioned rearward from the center of 1.

By doing so, when inserting a shoe into the holder 3, the shoe can be held at an appropriate position relative to the stepping surfaces 1a, 1b of the pedal body 1.

In addition, when the leg pieces 8 and 9 of the holder 3 are attached to both sides of the pedal body 1 in the left and right direction, the mounting surfaces on both sides of the pedal body 1 are flat surfaces in the front and rear direction perpendicular to the axis of the pedal shaft 2. Although the leg pieces 8.9 may be attached to a flat surface, preferably, as shown in FIGS. 1 to 4,
Mounting surfaces 13.1 provided on both left and right sides of the pedal body 1
4 are inclined forwardly and outwardly, and the mounting surfaces 13.14 are provided with threaded holes 12.4 perpendicular to the surfaces of the mounting surfaces 13.14. 12 are bored, and the leg pieces 8.9 of the holder 3 are attached to these screw holes 12.12.

That is, the pivot center line a, by which the leg pieces 8 and 9 of the holder 3 are pivoted on both sides of the pedal body 1 in the left-right direction, is inclined so that the inner side is located in front of the pedal body 1 with respect to the outer side.

By doing so, when inserting a shoe into the holder 3 and swinging the holder 3 forward, each of the leg pieces 8 and 9
As a result, the locking body 4 is attracted to the stepping surface side of the pedal body 1, and the holding force of the shoe can be further strengthened.

The legs 8 and 9 of the holder 3 described above may have the same shape, but preferably, as shown in the figure, one of the legs 8 and 9, that is, the leg 9 located on the outer side, The depression surface 1a of the pedal body 1 may be formed into a large circular shape as shown in the drawings.

It is possible to prevent the shoes inserted into 1b from escaping outward.

Further, the locking body 4 may be formed into a flat plate shape, but preferably, the back/surface 41 side of the locking body 4 is formed as shown in FIG.
The central part thereof is formed as a flat surface 4a, and the rear part continuing from the flat surface 4a is an upwardly inclined surface 4b that slopes upward toward the rear end, while the front part continuing from the smooth surface is formed downward toward the distal end. If the shoe is formed to have a downwardly inclined surface 4c that is inclined at a downward angle, it is possible to make it easier to insert and remove the shoe from the holder 3, and to further increase the holding force for the shoe. be.

That is, the shoes can be guided by the upwardly inclined surface 4b of the rear part, and the shoes can be strongly pressed by the downwardly inclined surface 4c of the front part.

Further, in the embodiment described above, the holder 3 consisting of the locking body 4 and the legs 5 and 6 is integrally formed of a synthetic resin material, and the holder 3 is made of a synthetic resin material.
are pivotally mounted on both sides of the pedal body 1 in the left and right direction, and the locking body 4 is forced to be displaced by swinging toward the stepping surface side via the legs 5 and 6 of the holder 3. 5,6
is formed integrally with the locking body 4 from a flexible soft resin material, or separately from the locking body 4 from a flexible material such as leather, for example, formed from a rigid material. The retainer 3 may be formed by attaching the locking body 4 by caulking or the like.

In such a configuration, the leg pieces of the leg body may be fixed to both sides of the pedal body 1 in the front and rear direction, or may be pivotally attached.

When fixed, the upper part of the leg swings in the front-rear direction of the pedal body 1, displacing the locking body 4 toward the depression surface of the pedal body 1.

As explained above, the present invention is a holder consisting of a locking body that extends in the front-rear direction of the pedal body and has a tread surface, and a pair of legs that extend from both sides of the locking body in the left-right direction of the pedal body. , and the retainer is attached to both sides of the pedal body in the left-right direction so that the locking body is displaced in the front-back direction of the pedal body and in the direction toward or away from the stepping surface, Shoes can be attached to and removed from the pedal by simply inserting and removing them between the tread surface and the holder, eliminating the need for attachment and detachment using locking devices. By inserting the locking body, the locking body is displaced in the front direction and close to the stepping surface, which presses the shoe strongly and strengthens the holding force of the shoe when the pedal is depressed. When the shoe is moved in the release direction, the locking body is displaced backward and away from the stepping surface, so the holding force on the shoe is immediately lost, and the shoe can therefore be removed quickly. This makes it possible to prevent unexpected accidents such as when a bicycle falls over.
