Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding pedal for a bicycle.

[0002]

2. Description of the Related Art In recent years, folding pedals for bicycles have been widely used in bicycles for the purpose of effectively utilizing bicycle parking lots, etc., especially for the purpose of compacting protruding pedals. In particular, those disclosed in Japanese Utility Model Publication No. 62-34877 and Japanese Utility Model Publication No. 5-1689 are common.
The former is to fold the pedal by rotating the pedal tread, and a stopper shaft slidably fitted on the pedal tread is biased by a spring, and a fitting wall provided at the tip of this stopper shaft. The pedal can be folded and assembled by freely fitting into and out of a fitting wall receiving port formed at the center of the tip of the pedal rotating body.

The latter also folds the pedal by rotating the pedal tread, and slides the pedal tread that is pivotally supported by the pedal body by a sliding button that is arranged in a direction perpendicular to the pedal main shaft. After pressing the button and moving it in the direction coaxial with the main shaft of the pedal, it can be rotated and folded.

[0004]

However, in the former configuration, when the pedal is folded, the fingertip is required to have a force to strongly pull out the knob when the pedal is squeezed outward by the force that overcomes the force of the spring. The operation is difficult. Further, the pedal rotating body has a fitting wall receiving port at the center thereof, and if dust, sand, water, or the like enters from there, it may deteriorate the performance of the pedal.

In the latter case, it is possible that the rider is confused because the procedure is such that the pedal step plate is moved in the direction coaxial with the pedal main shaft while pressing the slide button and then rotated and folded.

The present invention solves the above problems, and an object thereof is to facilitate folding and assembling operations of a pedal.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a pedal which has a fitting opening formed in a substantially central portion of a pedal tread, and which can be fitted into and out of the fitting opening freely. Along with slidably fitting in the hole formed in the center of the main body, a spring is urged in the direction of fitting with the fitting opening, and a through hole communicating with the fitting opening is formed in the center of the pedal tread. A pressing shaft as an operation member for operating the fitting body in a direction in which the fitting body is disengaged from the fitting opening is slidably disposed in the through hole.

[0008]

In the above structure, when the pedal is folded, the fitting member is pushed by the operating member so that the fitting member is disengaged from the fitting opening formed in the central portion of the pedal tread plate, and the pedal tread plate becomes rotatable. Can be folded.

Next, when assembling the pedal, the pedal tread is rotated toward the running position, and when the pedal tread reaches the running position, the fitting body is fitted into the fitting port by the biased spring, The pedal tread is fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
This will be described with reference to FIGS. 4, 5 and 6. In FIGS. 1 and 2, reference numeral 1 denotes a pedal main shaft, and a pedal main body 2 is rotatably fixed to the pedal main shaft 1. The pedal step plate 3 is connected to the pedal body 2 by the shaft 4 perpendicular to the axial direction of the pedal main shaft 1.
It is rotatably supported by. A fitting opening 3a is formed in substantially the center of the pedal step plate 3, and a fitting body 5 capable of fitting with the fitting opening 3a is slidably fitted in a hole formed in the substantially central portion of the pedal body 2. , Mating port 3a
Is urged by a spring 7 in a direction to be fitted with. Here, in order to prevent the fitting body 5 from jumping out, a groove 5a is formed on the side surface of the fitting body 5, and the tip portion of the screw 6 fixed through the screw hole 2a provided on the side surface of the pedal body 2 is formed into the groove 5a. It is inserted in. In addition, a fitting port 3a is provided at the center of the pedal step plate 3.
A pressing shaft 8 as an operating member having a through hole 3b communicating therewith and having a pressing head 8a at one end which is larger than the diameter of the through hole 3b and presses the fitting body 5 in a direction in which the fitting body 5 is out of fitting. Is the pressing head 8a in the through hole 3b.
It is arranged slidably on the side a. A button 9 is fixed to the pressing shaft foot portion 8b at the other end of the pressing shaft 8,
Then, the pressing shaft 8 and the button 9 are attached to the pedal tread 3
Is urged by a spring 10 in a direction projecting to the outside.

In FIGS. 5 and 6, the fitting body 5 is formed with a slanted surface portion 5b which comes into contact with the entrance portion 3c of the fitting opening 3a when the pedal is folded, and the fitting body 5 and the fitting opening 3 are formed.
The flat portion 3 formed in the fitting opening 3a when the
A flat surface portion 5c that abuts d is formed.

The bicycle folding pedal according to the present invention has the above-mentioned construction and is used as described below.

To fold the pedal, in FIG. 3 (a), when the button 9 is pushed, the pushing shaft 8 moves and the pushing head 8a and the fitting body 5 come into contact with each other, and when the button 9 is pushed further,
As shown in FIG. 3 (b), a force is applied from the contact portion, the fitting body 5 moves and disengages from the fitting opening 3a, the pedal step plate 3 becomes rotatable, and the pedal can be folded as shown in FIG. 3 (c). it can. When the button 9 is released, the button 9 and the pressing shaft 8 return to their original positions by the action of the spring 10.

Next, when assembling the pedal, in FIG. 4, when the pedal step plate 3 is rotated toward the traveling position,
The slope portion 5a formed on the fitting body 5 according to FIGS. 5 and 6 and the entrance portion 3c of the fitting opening 3a come into contact with each other. When the pedal step plate 3 is further rotated, the fitting body 5 moves smoothly due to the influence of the slope portion 5a, and the pedal step plate 3 can rotate to the traveling position. At this time, the fitting body 5 is fitted into the fitting port 3a by the action of the spring 7. The pedal board 3 is fixed. Even if a large force is applied to the pedal during traveling, the fitting port flat surface portion 3d and the fitting body flat surface portion 5 are
By sufficiently taking the contact surface of c, it can withstand the force.

[0015]

As described above, the folding pedal for a bicycle according to the present invention is provided with the fitting body urged by the spring, the pressing shaft and the button for moving the fitting body, and the fitting opening formed in the central portion of the pedal step plate. Thus, when the pedal is folded, the pedal tread is rotated while pressing the button, and when the pedal is assembled, it is only necessary to rotate the pedal tread toward the traveling position, and therefore the operation is easy.

Further, by forming an inclined surface portion which abuts the entrance of the fitting opening on the fitting body, the fitting body can be smoothly moved when the pedal is assembled.
