Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating pedal for a motorcycle, and more specifically, the present invention relates to an operating pedal for a motorcycle, and more specifically, an arm portion fixed to an operating shaft protruding outside the vehicle body and extending along the outside of the vehicle body, and a distal end portion of the arm portion. The present invention relates to a motorcycle operation pedal that is rotatably attached via a spring member and has a pedal portion that projects outward from an arm portion.

Generally, this type of operation pedal is used as a change pedal, brake pedal, etc. in motorcycles such as off-road vehicles, and when the pedal is banked, the outer end of the pedal comes into contact with the road surface and receives impact force. In this case, the pedal section rotates toward the arm section against the spring member to avoid damage to the operation pedal. By the way, in the conventional operation pedal of this type, the pedal part is formed into a rod shape, and a coil-shaped torsion spring is used as a spring member, and the pedal part is rotatably attached to the arm part to this torsion spring. The torsion spring is assembled by positioning the torsion spring between the head of the pin and the top surface of the pedal with the pin inserted. For this reason, the head of the pin protrudes upward by the thickness of the coiled portion of the torsion spring at the attachment point to the arm of the pedal.
It will come into contact with the soles of the pilot's feet. Therefore,
When operating the control pedals, the operator feels a large foreign object on the soles of his feet, and there is also the risk of hurting the soles of his feet. Additionally, since the torsion spring is in constant contact with the soles of the operator's feet and is also close to the road surface, it is easy for mud etc. to adhere to it, which may impair the function of the torsion spring, so we will compensate for this. To avoid this, the area must be covered with a protective cover such as rubber.

The present invention was made in view of the above-mentioned circumstances, and its main purpose is to form the pedal part of this type of operation pedal into a shape having an internal space, and to employ a tension spring as the spring member. By tensioning the tension spring within the internal space of the pedal portion, the above-mentioned problems associated with conventional operation pedals are solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 and 2 show an example of a change pedal according to the present invention. The main components of this change pedal include an arm portion 10 fixed to an operating shaft (not shown) that protrudes outside the vehicle body, and a pedal portion 20 attached to the tip of the arm portion 10. The arm portion 10 is fixed to the operating shaft and extends forward along the outside of the vehicle body, and has a mounting pin 3 at a mounting portion 11 provided at the tip thereof and protruding outward.
1, the pedal section 20 is rotatably attached to the arm section 10 side. This pedal section 20 is
It is attached via a tension spring 32, which is a spring member, and protrudes outward from the tip of the arm section 10 under the tension of the tension spring 32.

The change pedal is actuated by the operator pressing and lifting the pedal portion 20 with his or her toe, and thereby the operator operates a shift mechanism (not shown) to appropriately change the speed of the motorcycle.
Furthermore, when the outer end of the pedal section 20 receives an impact force, such as when the outer end of the pedal section 20 contacts the ground in the event of a puncture of the motorcycle, the pedal section 20 will release the tension as shown by the imaginary line in FIG. It rotates toward the arm portion 10 against the tension of the spring 32.

As shown in FIGS. 1 to 4, the pedal section 20 is formed into a cylindrical shape having an internal space, and a U-shaped mounting section 2 is provided at the inner end of the cylindrical section 21.
2 is formed to protrude inward. This mounting part 22
are two upper and lower flat plates 22a, 22 that protrude inward.
b, and these two flat plates 22a, 2
The plate-like attachment part 11, which is formed to protrude outward from the tip of the arm part 10, is inserted between the arms 10 and 2b, and is rotatably attached to the arm part 10 by vertical attachment pins 31. Further, the change pedal employs a tension spring 32 as a spring member. The tension spring 32 has a coil shape, and the coil portion 32
The outer diameter of a is slightly smaller than the inner diameter of the cylindrical portion 21 of the pedal portion 20. This tension spring 32 is interposed in the inner hole 21a of the cylindrical portion 21 of the pedal portion 20, and has an inner end 32b.
is locked to the mounting portion 11 of the arm portion 10, and its outer end 32c is locked to a locking pin 33 that penetrates and is implanted in the outer end of the cylindrical portion 21. The locking portion of the inner end 32b of the tension spring 32 is offset forward and outward from the center of rotation of the pedal portion 20, as shown in FIG. As a result, the tension spring 32 is tensioned in the inner hole 21a of the pedal section 20, and its tension urges the pedal section 20 to protrude to the outside of the arm section 10, and the inner end surface of the mounting section 22 is The distal end portion of the arm portion 10 is stopped by coming into contact with the outer surface thereof, and when the cylindrical portion 21 of the pedal portion 20 receives an impact force, the pedal portion 20 is allowed to rotate toward the arm portion 10 side.

In the change pedal configured in this way, the pedal part 20 is formed into a cylindrical shape having an internal space, and the tension spring 32 is employed as a spring member, so that the inner end 32b of the tension spring 32 is engaged with the arm part 10. and the outer end 32c of the pedal part 20 is locked in the inner hole 21a, and the tension spring 32 is inserted in the inner hole 21a.
is being set up. Therefore, the tension spring 32 is not exposed to the outside, and the head of the mounting pin 31 does not protrude significantly above the mounting area. Therefore, even if the operator operates the change pedal, he will not feel a large foreign body sensation on the sole of his foot or hurt the sole of his foot, and the tension spring 32 will not be damaged due to mud etc. adhering to the tension spring 32. The function of the tension spring 32 is not impaired at an early stage, and there is no need to sufficiently cover the relevant part with a protective cover to compensate for the deterioration of the function of the tension spring 32. Further, the tension spring 32, which is locked to the tip of the arm section 10 at a position where the inner end 32b is deviated forward and outward from the mounting pin 31, allows the pedal section 20 to be attached to the arm section without being affected by friction. 10 to a position protruding outward.

In the present invention, a spring member having an appropriate shape may be used as the tension spring, and the arm portion and the pedal portion may also be formed into an appropriate shape. Further, when carrying out the present invention, it is preferable to close the outer end opening of the cylindrical pedal part, thereby more reliably preventing functional deterioration of the tension spring due to adhesion of mud, etc. Can be done. Furthermore,
It goes without saying that the present invention can be applied to a brake pedal, which is an operation pedal for a motorcycle.

As explained above, in the present invention, the distal end of the arm is rotatably attached via the vertical mounting pin, is biased by a spring member to protrude outward from the arm, and the outer end The pedal part, which rotates toward the arm part against the spring member when the part receives an impact force, is formed into a shape with an internal space, and a tension spring is used as the spring member, and one end of the pedal part is connected to the mounting pin. The tension spring is latched to the tip of the arm at a position deviated forward and outward, and the other end is latched within the inner hole of the pedal, so that the tension spring is tensioned within the internal space of the pedal. Particularly noteworthy are its structural features.
Therefore, according to the present invention, the tension spring is not exposed to the outside, and the head of the mounting pin is not made to protrude significantly above the mounting area, causing the operator to feel a large foreign body sensation. Moreover, it is not necessary to sufficiently cover the relevant part with a protective cover in order to compensate for the deterioration of the function of the tension spring.

Also, if the external force applied to the tip of the pedal is removed,
The pedal part is almost unaffected by friction, and the tension spring reliably returns it to the position where it protrudes outward from the arm part.
