[Problems to be solved by conventional technology and device]

 Conventionally, most pedals in bicycles have been integrated, but in recent years portable bicycles, such as folding bicycles, have become popular, and most of the portable bicycles use folding pedals. For example, Republic of China Utility Model No. 271153 “Improvement of folding bicycle pedal”, Republic of China Utility Model No. 275865 “Folding pedal”, and Republic of China Utility Model No. 340508 “Ball folding pedal” are examples. is there .

The conventional “improvement of the folding bicycle pedal” has a U-shaped frame 40 as shown in FIGS. 6 and 7, and connecting bodies 41 near both ends of the U-shaped frame 40. A shaft hole 42 is formed in the connecting body 41, and a main shaft 43 is pivotally mounted in the shaft hole 42 by a bearing (not numbered). ). Also, as a feature, a square block body 44 is installed inside the U-shaped frame body 40, a circular hole 45 is formed in the center of the square block body 44, and circular holes 45 are formed on the top and bottom surfaces. An elongate hole 46 is formed, which communicates with the hole. Further, the spring 47 and the circular tube 48 are inserted into the circular hole 45, and a through hole 481 is formed on the tube surface of the circular tube 48. The through hole 481 corresponds to the long hole 46. Then, a pair of T-shaped pins 49 are inserted into the long hole 46 and the through hole 481 from above and below, respectively. At this time, one end of the circular tube 48 is exposed from the circular hole 45, and the exposed portion enters the shaft hole 42 at the rear end of the connecting body 41.

However, in the above-described design, when the user holds the bicycle, the sole of the foot is easily caught by the T-shaped pin 49, and in some cases, the circular tube 48 is moved by the hook, and in the worst case, This is extremely dangerous because one end of the circular tube 48 may come off the shaft hole 42 of the connecting body 41.

As shown in FIG. 8, the conventional “foldable pedal” includes a main body 50 and a pedal frame body 60, the main body 50 is a convex body, and a main body 50 is provided in a circular hole 51 at one end thereof. A shaft 52 is pivotally mounted, a circular fitting groove 53 is formed at the other end, and a block 54 is provided at each end of the main body 50. 55 are provided, and convex fixing blocks 56 are provided on both sides of the other end of the main body 50, respectively. Further, two quadrangular holes 61 are formed near one end of the pedal frame 60, and a circular fitting body 62 protrudes from the outer wall surface of the quadrangular hole 61, and both sides of the inner wall surface of the pedal frame 60. Sliding grooves 63 are formed at the ends, receiving holes 64 are respectively formed at the ends of the sliding grooves 63, and contact pieces 65 are respectively provided outside the receiving holes 64. Thereby, the bolt 66 can be screwed into the screwing hole (not shown) of the fixing block 56, and the bolt 66 is located in the lateral groove 67 in the pedal frame 60, so that the pedal frame 60 can move laterally. Become.

However, in the above design, the bolt 66 is simply screwed into the fixing block 56 of the main body 50 and the outer peripheral surface of the bolt 66 is located in the lateral groove 67 of the pedal frame 60. There is a risk that the bolt 66 will loosen and fall off during use.

As shown in FIG. 9, the conventional “ball-type folding pedal” includes a pedal tread plate 70 and a pedal seat 80, and a convex shape pivotally connected to the pedal seat 80 on one side of one end of the pedal tread plate 70. A bottom portion of the ear portion 71 is formed in a step shape, a cylindrical member 72 is provided in the middle of both ear portions 71, and a screwing hole 73 is formed in the cylindrical member 72; A spring 84 is fitted into the screw hole 73. Further, the opening of the screw hole 73 is screwed with the ball seat 81 to form an inner hole 82 for fitting the ball 83 into the ball seat 81, and is stopped at the end of the ball seat 81 in the inner hole 82. An edge (unsigned) is provided and a portion of the ball 83 is exposed from a stop edge at the end of the ball seat 81. The bottom of the ear 71 corresponds to a stop block 86 for preventing the pedal tread plate 70 from shifting downward, and an arc-shaped groove 85 is formed from the upper surface at the center of the pedal seat 80 to the side surface near the pedal tread plate 70. Positioning portions 851 and 852 having a depth greater than that of the arc-shaped groove 85 are formed at both end portions of the arc-shaped groove 85. Therefore, the folding operation can be easily performed by the ball 83 moving in the arc-shaped groove 85.

However, in the above-described configuration, since the ball 83 moves while being in contact with the spring 84, the arc-shaped groove 85 and the positioning portions 851 and 852 are enlarged when used for a long time, causing a problem in positioning. There is fear.
