Description

  The present invention provides a bicycle that can be easily raised from a conventional bicycle by attaching an auxiliary tool to the pedal of the commercially available bicycle.

Previous commercial bicycles have no device to press the foot against the pedal. The gazette shown in Patent Document 1 has the same idea regarding the necessity of foot press, but the height adjustment mechanism is different, and cannot be handled by a pedal of a commercial bicycle.
Japanese Patent Laid-Open No. 2-185844

In the pedals of commercial bicycles up to now, the force of stepping down is used as a source of rotational force, and the effect of lifting the foot cannot be used. On the contrary, the other foot of the foot to be stepped on has a foot on the pedal, so the rotational force is reduced.
In addition, the pedal of the bicycle for competition is equipped with a foot fixing device, but it cannot be easily removed when it is a saddle, or it is necessary for the general public to use special shoes. There are many problems.

A latching portion that holds down the instep of the foot on the pedal from above, and a latch projection that is lowered at a right angle from one end of this latching portion and that is responsible for the height adjustment and holding function of the latching portion on the front surface of the lower end. A foot holding plate having a support portion provided with a latching elastic body on the lower back surface;
A foot press plate support case that is fixed to a vertical portion of a pedal mounting base, which will be described later, and forms an insertion hole for guiding its movement when the support portion of the foot press plate is inserted;
The foot presser plate support case is supported on the crank arm side of the pedal, and the height of the foot presser plate locking portion is adjusted by interacting with a latching projection provided on the lower front surface of the foot presser plate support portion. And a vertical portion having a plurality of latch recesses for holding functions, a rectangular horizontal portion having the same dimensions as the pedal tread surface to be attached to the lower surface of the pedal, and a pedal shift bent vertically from the other three sides of the horizontal portion. It consists of prevention claws, and when it is assembled integrally with the above two parts and fixed to the lower surface of the pedal, the entire center of gravity including the pedal is located below the pedal so that the locking part of the foot holding plate is above the tread surface of the pedal And a pedal mount having a weight.
Among the above components, the foot retainer plate including the elastic body is detachable, the foot retainer plate support case and the pedal mounting base are integrated, and fixed to the lower part of the commercially available bicycle pedal so as to be integrated with the tread surface.

As an effect of the present invention, the leg strength of both feet can be used at the same time, so it is easy to bounce, and if the foot is pressed against the pedal from above, there is no need to put force so that the foot does not leave the pedal while running, so You can make it easily.
When you feel danger while running, you can easily free your feet by pulling your feet to the side or back.
When the assisting tool is fixed to the pedal, the center of gravity of the entire pedal is below the pedal, so the foot retainer is always at the top, making it easy to get on the foot, and when the foot retainer is not needed, remove only the foot retainer. Can be used.

The devised bicycle pedal assisting device for foot press functions as a pair, but the left foot will be described with reference to the drawings.
Fig. 1 is an overall perspective view of the pedal assisting device attached to the pedal, but when the foot is not on, the entire center of gravity is placed below the pedal and the foot press plate 1 is placed above the pedal tread surface. The plate 1 and the foot holding plate support case 3 are made of a light material with rigidity such as aluminum or synthetic resin, and the pedal mount 4 is made of a heavy material such as an iron plate.

Further, the inside of the fracture surface shows the fitting state of the latching protrusion 1a of the foot pressing plate and the latching recess 4b provided on the foot pressing plate support case support portion 4a of the pedal mounting base. The angle is such that the resistance is small in the direction in which 1f is inserted into the support case 3 and it cannot be removed unless the latch is released when it is pulled out. The angle of the latch recess 4b is approximately 60 degrees, and the angle of the latch protrusion 1a is approximately 40 degrees. Is desirable. The width of the latch recess 4b may be about 5 mm, and the width of the foot pressing plate support 1f including the latch protrusion 1a may be the same. The fitting depth between the latch recess 4b and the latch projection 1a is preferably about 3 mm.

  FIG. 2 is an overall assembly diagram including a commercially available pedal, but the discomfort of the instep is eliminated by attaching the cushioning material 1d to the locking portion 1e of the foot pressing plate.

  Further, the foot holding plate support case 3 is placed on the support portion 4a and fixed to the pedal mounting base 4 with two fixing screws 3a. The size of the insertion hole for the foot pressing plate support portion 1f generated thereby is set to a width plus 1 to 2 mm of the latch recess portion 4b in the width direction, and a dimension in which the latch can be released in the depth direction.

  FIG. 3 is a perspective view showing the positional relationship between the pedal mounting base 4, the fixing band 5, and the pedal displacement prevention claw 4 c, but the function of the fixing band 5 is to hold the pedal mounting base 4 on the pedal as shown in FIG. This is used to fix the pedal through the fixing band hole 4d and is provided with a pedal displacement prevention claw 4c bent up from three sides of the pedal mounting base 4 to prevent the pedal and the pedal mounting base 4 from slipping. . Further, the foot pressing plate support case support 4a is manufactured integrally with the pedal mounting base 4, and the horizontal angle of the entire latch recess 4b is about 60 degrees.

  FIG. 4 is an enlarged view of the latch action portion of the foot pressing plate support portion 1f. The L-shaped rod-like elastic body 2 is inserted into the deepest portion of the L-shaped rod-like elastic body support hole 1b, and the short-side end is inserted. Is held in a state bent into the L-shaped rod-shaped elastic body guide hole 1c.

  At this time, the distance between the back surface of the foot pressing plate support portion 1f and the L-shaped elastic body 2 is 3 mm or more necessary for releasing the latch recess 4b and the latch projection 1a. Further, the latch action portion of the foot presser plate support portion 1f including the L-shaped bar-shaped elastic body 2 is inserted into an insertion hole formed by the foot presser plate support case 3 and the foot presser plate support case support portion 4a of the pedal mounting base 4. Then, the latch protrusion 1a of the foot retainer support 1f is fitted into the latch recess 4b of the foot retainer support case support 4a at an arbitrary height. At this time, it is the role of the inner wall of the back surface of the insertion hole of the L-shaped bar elastic body 2 and the foot pressing plate support case 3 that presses the latch portions and takes charge of maintaining the height of the foot pressing plate 1.

  FIG. 5 shows a state in which the L-shaped bar-shaped elastic body 2 is bent and its apex enters the L-shaped bar-shaped elastic body guide hole 1c. When the upper part of the foot presser plate 1 is pushed forward by hand, the upper end of the foot presser plate support case support 4a becomes a fulcrum, and a force for bending the L-shaped bar-shaped elastic body 2 is applied, and the L-shaped bar-shaped elastic body 2 is bent. As a result, the latch protrusion 1a of the foot retainer support 1f and the latch recess 4b of the foot retainer support case support 4a are released and the foot retainer 1 can be pulled out.

Further, during insertion of the foot retainer support 1f into the insertion hole formed by the foot retainer support 3 and the foot retainer support 4a of the pedal mount 4, the L-shaped elastic body 2 is shown in FIG. 5 is repeated.
The above is one form of this invention, and an application form is demonstrated below.

  FIG. 6 shows a deformation of the foot press plate, in which a square member is bent to constitute a locking portion and a support portion.

  The elastic body may be a plate-like elastic body having the same width as the diameter of the rod-shaped elastic body.

  FIG. 7 shows a form in which the pedal mount is screwed to the pedal. A female screw is formed on the front and rear displacement prevention claws of the pedal mount to restrain the side of the pedal.

  FIG. 8 shows an example of the shape and formation position of the deformation of the pedal misalignment prevention claw.
