DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle pedal strap.

[0002]

2. Description of the Related Art In a conventional bicycle pedal strap, one toe of the pedal is used to turn the toe portion of the foot once around and tightened to fix the pedal to the pedal.

[0003]

In a conventional bicycle pedal strap, since one strap is tightened around the toe of the foot, if the strap is tightened strongly, the foot cannot be pulled out in an emergency. Even if loosened, the foot must be pulled backwards, making it difficult to quickly reach the ground in an emergency, and there is a risk of falling.

According to the present invention, even when the strap for a bicycle pedal is strongly tightened, the strap can be instantly removed without using a hand or the like, and the foot can be quickly attached to the ground, so that the bicycle can be safely driven. It is intended to contribute.

[0005]

In order to achieve the above object, in the instant release metal fitting according to the present invention, a plate-shaped hook for receiving tension, a buckle which is disengaged when displaced outward,
A magnet for attaching the buckle to the plate hook is attached.

[0006] The above-mentioned release fitting is a method in which a metal plate-shaped hook capable of sufficiently withstanding the tension applied to the strap is attached to the rear outer portion of the bicycle pedal, and a magnet described later, which attracts a buckle and adheres tightly, is fixed to the plate-shaped hook. Have been.

[0007] The buckle is connected by a hinge to a hook having a U-shaped cross section which is in close contact with the plate-shaped hook and receives tension applied to the strap. The claw having the U-shaped cross section is fixed to the plate-shaped hook. It will be attracted by the magnetic force of a certain magnet.

Further, the plate-shaped hook is slightly narrower than the buckle and slightly inclined outward, so that when the buckle is set and tension is applied to the strap, the hook can protrude from between the buckles. Further, it is preferable that the inner angle of the return portion of the plate-shaped hook be slightly acute rather than a right angle.

[0009]

In the bicycle pedal strap which can be released instantaneously as described above, the plate-shaped hook runs out from between the buckles when tension is applied to the strap, and a cross section is formed at the return portion. The corner of the tip of the U-shaped claw is pressed and receives the tension.

In addition, the heel of the foot is moved outward while the strap is tightened, that is, the buckle is pushed outward and the corner of the tip of the U-shaped claw is formed at the return portion of the plate-shaped hook. At the moment when the tension shifts to the outside of the pressed point, the claw with a U-shaped cross section comes off from the plate hook,
Release the buckle at the same time.

[0011]

Embodiments will be described with reference to the drawings.
In FIG. 1, a plate-shaped hook having a magnet 3 fixed thereto is attached to the outside of the bicycle pedal 1. At the end of the strap 7,
A buckle 4 having a claw 6 having a U-shaped cross section connected by a hinge 5 is attached.

In the embodiment shown in FIG. 2, the claw 6 having a U-shaped cross section is attracted to and set by the magnet 3, and the claw 6 having the U-shaped cross section is also positioned by the magnet 3 in the lateral direction. The buckle 4 does not hinder the movement of the buckle 4 in the set state.

In the embodiment shown in FIG. 3, FIG. 3 is a conceptual diagram of a mechanism for instantaneously releasing the buckle. Plate hook 2
In the case where the point at which the tip of the claw 6 having a U-shaped cross section contacts the return portion of B is B and the tension A pulling the point C with the hinge 5 as the point C is on the left side of the dotted line connecting C and B, Then, the plate-shaped hook 2 receives tension. However, at the moment when the tension A moves to the right and crosses the C and B lines and moves to the right,
The point C of the hinge 5 comes off the hook 2.

In the embodiment shown in FIG. 4, the bicycle pedal 1 is fitted with the toe clip 9, the metal fitting of the present invention which can be released instantaneously, and the strap 7, and the foot is inserted.

[0015]

Since the present invention is configured as described above, it has the following effects.

Even when the toe portion is tightened and fixed with the bicycle pedal strap, if the heel is slightly shifted outward, the metal fitting is released instantaneously, so that the foot can quickly reach the ground.

Further, when the detached buckle is set on the plate-shaped hook again, the magnet serves as a guide, so that it can be quickly set at a fixed position.
