Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedal structure mainly used for bicycles or bicycle-type exercise machines.

[0002]

2. Description of the Related Art A pedal related to this is described in Japanese Patent Application No. 7-344507 by the present inventor as a pedal for a cycle exerciser. The structure is provided with a pair of disc-shaped piece seats near both ends of the pedal shaft, and between them, a plurality of rows of piece shafts provided with a rotatable finger pressure piece along the outer periphery of the piece seat.

[0003]

However, in order to fix the pedal shaft to a pair of disc-shaped tops, a hole for fitting the tip of the top to the predetermined position of the top is formed. They were provided, an adhesive was applied, and they were fitted together. However, because the pedal part is a structure that stimulates the sole of the foot with acupressure as it rotates, it vibrates constantly, and even if it is bonded with an adhesive, the bond separates, and the fitting part at the end of the coma shaft is seated However, there was a drawback that the fitting holes of the two started to wear due to rubbing against each other and eventually cut. Also,
Since strength cannot be obtained unless adhesive is applied to the fitting parts at both ends of the frame shaft, even if one frame shaft is cut after the pedal is assembled, the frame seat is removed and repaired for replacement. Couldn't do.

The present invention is directed to these problems, namely, a number of assembling steps of fixing the top seat to the pedal shaft and fitting and adhering the individual top shafts to the top seat, and the assembly of the top shaft and the top seat. It aims to solve the contact wear with the fitting hole, save labor in the assembly process, and eliminate the disconnection failure of the top shaft.

[0005]

In order to solve this problem, the present invention has a structure of a pedal to be attached to a crank of a bicycle or a cycle exercise machine. On the base,
A plurality of metal top shafts are projected and integrally fixed. B. A shiatsu top is rotatably inserted in each top shaft. C, the mounting cylinder and the upper end of the top shaft are fitted and inserted in the fitting insertion pipe and the fitting insertion hole provided in the top shaft cap, and are fixed so as to maintain a predetermined position. In addition, insert it into the core shaft fixed to the crank, and fix it so that it cannot rotate.

Prior to use, the Japanese Patent Application No. 7-
As described in 344507, when the crank rotates because the pedal itself is fixed to the pedal shaft,
The pedal itself will rotate while rubbing the bottom of the foot. Therefore, at this time, the acupressure piece inserted into the top shaft attached to the outer periphery of the pedal rotates, and a shiatsu massage effect is exerted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described in detail below with reference to the drawings. 1 and 2 are explanatory views showing the structure of an embodiment of the present invention. First, in the structure of the pedal, six pieces of metal piece shafts 4 made of stainless steel or the like are provided integrally on a resin-made piece shaft base 3 having a mounting cylinder 2 that can be mounted on the pedal mounting shaft 1 protruding in the center. . The integration is, as shown in FIG. 3, on the outer periphery of the lower end of the top shaft 4,
A thin groove 5 and a net-shaped knurl 6 are formed, or as shown in FIG. 4, a flat groove 5 is formed on the lower end of the top of the top, and the top of the top of the top 3 made of resin is placed at a predetermined position. Place 4 end portions and perform encapsulation molding. As a result, the resin-made frame shaft base 3 and the metallic frame shaft 4 are integrated, and even if a strong vibration is applied, the frame shafts 4 may start to rotate or come out without being separated from each other. Disappear. The structure of the terminal of the frame shaft 4 is such that only the knurl 6 is provided and the groove 5
May be omitted. In addition, another shape may prevent peeling between the lower ends of the frame shaft base 3 and the frame shaft 4.

Next, after the acupressure piece 7 is rotatably attached to the piece shaft 4, the piece shaft 4 and the upper end of the mounting cylinder 2 are
The fitting shaft 9 is fitted into the fitting cylinder 9 and the fitting hole 10 provided at a predetermined position. It should be noted that the fitting of the two is performed by cutting the shape of the pedal shaft 12 by a plane in which a part of the cylinder is parallel to each other in the figure, and by making the fitting inner surface of the mounting tube 2 to have a shape corresponding to the shape. Although the rotation deviation after the combination is prevented, other shapes may be used. Further, the pedal shaft 1 may be integrally molded in the mounting cylinder 2 by encapsulating and molding the pedal shaft 1 in accordance with the molding process of the frame shaft base 3 and the mounting cylinder 2. The shape of the acupressure piece 7 is shown as an abacus piece, but it may be another shape that is slender and integrated.

The pedal is mounted by fitting the mounting cylinder 2 to the pedal shaft 1 fixed to the crank 11, and then at the center position of the outer surface of the top shaft cap 8, the pedal shaft end portion is fixed by the screw 13. Tightly screw to 12. As a result, the pedal mounting shaft 1, the frame shaft base 3, the mounting cylinder 2, the frame shaft 4, and the frame shaft cap 8 are completely integrated to form the crank 11.
It can be easily disassembled if it is fixed to and the screw 13 is removed.

Therefore, when the rotation of the crank 11 rotates, the pedal relatively rotates on the sole of the foot, and the acupressure piece 7 rotatably attached to the top shaft 4 massages the sole of the foot. Exert.

[0011]

According to the present invention, the pedal shaft of the pedal of the cycle exerciser in which the acupressure piece is rotatably mounted is replaced by the iron pedal shaft 1 fixed to the crank 11,
The mounting cylinder 2 made of resin is mounted and configured. Further, the mounting cylinder 2 is integrally projectingly arranged in the center of the resin-made top shaft base 3, and a plurality of metal top shafts 4 are integrally formed by encapsulating and molding the lower ends of the tops thereof inseparably on the outer periphery thereof. All the top shafts 4 on which the tops 7 are mounted are strongly pressed by the screws 13 through the fitting holes 10 formed in the top shaft caps 8. Therefore, even if the top shaft 4 vibrates violently via the acupressure piece 7 due to the pedal movement performed by placing the foot,
There is no risk that the lower end of the top of the top frame 3 enclosed in the resin will separate, and the entire pedal will have an extremely strong structure, improving its durability.

The pedal shaft includes a pedal shaft 1 and a mounting cylinder 2.
Since it has a double structure of, the work of adhering and fixing the heavy crank 11 and the threaded portion of the pedal shaft 1 with a locking agent and the work of assembling the light pedal portion can be performed separately and then combined. The work process is easy and the efficiency can be improved.
Also, if necessary, the screw 12 can be completely disassembled by simply unscrewing it.
