Description of the invention (f) [Technical field to which the invention belongs] Please read the notes of the back first and then fill out this page This invention relates to folding pedals for bicycles which are easy and small and foldable. [Previous Technology] In recent years, folding bicycles for the purpose of diversifying leisure and saving space have been widely used up to now. Moreover, in order to effectively use a parking lot or the like even if it is not a folding bicycle, a folding pedal is often used. Generally speaking, there are those disclosed in Kaiping No. 5-1 689 or Shikaiping No. 6-72796. The former is a person who presses a button provided on the pedal body with a hand and slides the pedal while turning the pedal. In the latter case, the tread is formed on only one side, and is folded while pressing the opposite side of the tread while turning. In addition, although it is not practical, Japanese Patent Application Laid-Open No. 8-207866 also proposes a person who slides the foot pedal toward the crank arm to receive it. [Problems to be Solved by the Invention] Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, in the structure of Shikaihei 5-1689, one side of the button must be pressed with the other hand to slide the pedal and then folded back. Those are too complicated. Also, in the case of JP-A-8-207866, it can only be used on one side, so you must be very careful when you step on it. It is dangerous to fold the pedal when you step on the opposite side by mistake. In addition, in JP-A-8-207866, only sliding storage is required, and there is a problem that it cannot be downsized. The present invention aims to solve the above-mentioned problems in one fell swoop by providing a folding pedal for a bicycle that simplifies folding and combining operations and is safe at the same time. [Means for solving problems] In order to solve the above-mentioned purpose, the pedal axis direction of the pedal body of the present invention is adapted to the Chinese National Standards (CNS) A4 specification (210X297 mm) 477763 A7 B7 employees of the Ministry of Economic Affairs Printed by the consumer cooperative V.

The rotation center is provided with the rotation axis of the pedal 1 against the spring to complete the folding structure. [Embodiment of the Invention] According to the above-mentioned structure, when the pedal is folded, the pedal is moved toward the crank arm side against the spring, and the rotation center provided on the side of the pedal body and the rotation center provided on the pedal are matched. The board becomes swivelable and it is folded back. When the pedal is combined, before reaching the running position, if the foot pedal is turned, it will be automatically moved to the crank arm side and the opposite side by the spring foot pedal, and it will be usable. [Examples] The present invention will be described below with reference to the drawings. 1 and 2 are a top view and a side view of the traveling position. Side view 2 is a sectional view taken along the line A-B-C-D in Fig. 1. Figures 3 and 4 are top and side views when the footrest 2 is moved toward the crank arm 7 side when folded, and the rotation center 1d of the pedal body 1 and the rotation center 2a of the footrest 2 are aligned. Fig. 5 shows a state of being folded halfway, and Fig. 6 shows a state of being folded. Fig. 7 shows an embodiment of the present invention. Figures 8 and 9 show the operation with feet. The foot pedal 2 is slightly in shape, and is provided with a holding protrusion 2 b and a rotary shaft 2 a near the opening side, and an inner side of the closed side on the opposite side is provided with a spring 6 to support the crank arm 7 and the pedal body 1.的 压 罐 5。 The pressing cylinder 5. Pedal shaft 4 screwed -4- This paper size applies Chinese National Standard (CNS) A4 specification (210X 297 mm) 477763 A7 B7 V. Description of the invention (3) (Please read the precautions on the back ^; write this page) A crank rail 7 is rotatably combined on both sides of the pedal body 1 of the pedal shaft 4, and a retaining rail 1c is provided above the letter [], so that the rotary shaft 2a and the retaining protrusion 2b of the pedal 2 It is movable in the direction of the pedal shaft 4. Since the rotary shaft 2a is constituted by the wing portion 2c and the elliptical portion 2d, the wing portion 2c is held on the holding rail 1c so as to prevent the slightly-shaped foot pedal 2 from extending outward. The side of the crank arm 7 of the holding rail 1 c is an opening, and the opposite side is locked by the wall 1 a. In the state of the traveling position of the above-mentioned structure, the front end portion of the pressing cylinder 5 which is biased toward the pedal body 1 side by the spring presses the opening end portion 1 b of the pedal body 1 so that the pedal plate 2 is often aligned. The pedal body 1 is biased in the direction of the arrow, and the rotary shaft 2 a is abutted against the wall 1 a. At this time, since the rotary shaft 2 a and the holding protrusion 2 b are held by the holding rail 1 c, the pedal body 1 and the foot pedal 2 form an integrated state and can be used as usual pedals. · Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, and folded in the self-propelled position, in order to press the foot pedal 2 against the spring 6 toward the crank arm 7 side, that is, in the direction of the arrow. As long as the foot pedal 2 moves a certain distance, as shown in FIG. 3 and FIG. 4, the holding protrusion 2 b leaves from the opening 1 g of the holding rail 1 c, the rotation center 1 d of the pedal body 1 and the rotation axis of the foot pedal 2 The center of 2 a is the same, with the rotation axis as the center, and the foot pedal 2 can be turned. In this embodiment, when the center of rotation 1 d of the pedal body 1 and the center of the rotation axis 2 a of the pedal 2 are the same, the configuration in which the rotation axis 2 a abuts the stopper 3 can prevent the pedal 2 from moving toward the crank.

Description of the invention ($) (Please read the precautions on the back before filling this page) Rotary shaft and keep the protrusion, and The pedal is set to hold the rail. In short, the foot pedal is movable in the direction of the pedal axis. A spring acting in the direction of the pedal axis to move the pedal body and the pedal away from the direction is provided, so that the center of rotation provided on the side pedal of the pedal body is moved to make the center of rotation consistent. The folding can be completed. [Effects of the Invention] Conventional products do not have simple, safe and inexpensive, compact, three-item requirements. As mentioned above, as in Kaiping No. 5-1 689, if you do not press the button, it will not be folded. The system disclosed in Shikai No. 6-72796 can only use one side and therefore has security problems. In addition, in Japanese Patent Application Laid-Open No. 8-207 866, sliding storage is not a problem. However, according to the present invention, these problems can be solved at once, and a folding pedal that satisfies all three requirements can be provided. That is, without pressing the push button, the foot pedal is pushed toward the crank arm side, and the foot pedal can be folded by turning the foot pedal at a position where the center of rotation is consistent. In fact, these turning movements are turned almost unconsciously, and after folding, they can be kept folded by the resistance of the pressing cylinder 5 and the flat part of the pedal body, which are supported by the spring. When returning to the running position, you can automatically return by turning the foot pedal. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. As mentioned above, it can be folded and returned very easily, so it can be operated with feet. As shown in Figures 8 and 9, when folding, use the sole pedal to face When the pedal body is pressed, when the pedal is returned to the running position, it is only necessary to step on the pedal toward the pedal body side. It can be done without touching the dirty pedals with your hands, which is of great benefit. That is to say, not only folding bicycles, ordinary vehicles are stopped at the paper size to apply Chinese National Standard (CNS) A4 specifications (210X 297 mm) 477763 A7 B7--1 ~ -----., V. Description of invention (6) "When stored," although it is desirable to use the pedal because of the interference of the pedal, when there is a stomach, the hands are easily dirty. The invention can be loaded into a vehicle without any resistance, thereby contributing to space saving.
