る。Means to solve the problem The width of the main frame, which is rotatably supported on the pedal shaft, is reduced to about 1/2 to 2/3 of that of a normal pedal.
The base end parallel parts of the U-shaped auxiliary frame formed to fit this main frame are connected and overlapped from the tip side to the inside of the left and right side plates, which are constituent members of the main frame, and are provided near the base ends of the left and right side plates. A pin provided near the proximal end of the parallel base portion of the auxiliary frame is engaged with the guide elongated hole, and a pin provided on the distal end side of the parallel proximal portion of the auxiliary frame is engaged with the pin provided on the distal end side of the parallel proximal portion of the auxiliary frame. The outer plates connecting the auxiliary frame are inserted and engaged, and the auxiliary frame is pulled out toward the distal side with respect to the main frame, so that the entire structure can be expanded and contracted, and at least one parallel portion of the base end of the auxiliary frame is provided with a resilient spring. The telescopic bicycle pedal is characterized in that the auxiliary frame is held in a pulled out state by being attached with a stopper, the tip of which is engaged with a locking groove provided on the left and right side plates of a corresponding main frame.

れるのである。 A U-shaped auxiliary frame 8 is formed to fit the main frame 1, and pins 9, 10 are protruded from the outer surface of the base end parallel portions 8a, 8a closest to the base end.
Reference numeral 10 is engaged with long guide holes 11 and 12 formed in the left and right side plates 2 and 3 of the main frame 1, and guide window holes 13 provided near the tips of the base parallel portions 8a and 8a.
14, the outer plate 5 connecting the tips of the left and right side plates 2, 3 of the main frame 1 is fitted and engaged, and the parallel proximal parts 8a, 8a of the auxiliary frame 8 are connected to the left and right side plates 2, 3 of the main frame 1. It is connected and superposed on the inside and is provided so as to be able to slide in and out along the guide slots 11 and 12 of the main frame 1 and the outer panel 5,
Further, a stopper 16 is provided on one side of the base end parallel portion 8a of the auxiliary frame 8 and is resiliently pushed outward by a spring 15. When the auxiliary frame 8 is engaged with the groove 17 and pulled outward, it is held in that state.

動することがないのである。 Since this invented pedal has the above-mentioned configuration, the auxiliary frame 8 is provided so as to be able to slide in and out along the guide slots 11 and 12 and the outer panel 5 with respect to the main frame 1. When it is reduced by sliding it, its width becomes narrower to about 1/2 to 2/3 of the normal pedal.
This is particularly effective for folding bicycles, as it reduces the width of the bicycle and makes it more compact, making it easier to handle when storing and transporting. Furthermore, when riding, by pulling out the auxiliary frame 8 toward the tip side, the pedal stroke width can be easily expanded to 3/2 to 2 times or more, making it the normal width.
Since the auxiliary frame 8 is locked to the main frame 1, it is fixed in the extended position and can be easily pedaled like a conventional pedal. Furthermore, since the auxiliary frame 8 that expands the stepping width is pulled out toward the tip side relative to the main frame 1, most of the pedaling force is applied to the main frame 1, and the expansion of the stepping width does not become a weak point in terms of strength, making the structure robust. It is possible. In particular, the auxiliary frame 8 is formed in a U-shape with respect to the main frame 1, and connects the most proximal end and the distal end of the base end parallel parts 8a, 8a between the ends of the left and right side plates 2, 3 of the main frame 1. Since it is provided so as to be supported by the outer plate 5, it is supported at two points, inside and outside, so that the expansion and contraction operations can be performed smoothly and there is no vibration due to running vibrations.
よつて、格納場所をとらず、運搬に便利な折畳
み自転車等のペダルとして実用効果の多いもので
ある。 Therefore, it has many practical effects as a pedal for a folding bicycle, etc., which does not take up much storage space and is convenient to transport.
