Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a motorcycle brake pedal position adjustment device.

On a motorcycle, the depressing part of the brake pedal is located in front of the footstep where the driver places his or her foot, and the driver operates the brakes by depressing the brake pedal with the toe of the foot placed on the footstep. Therefore, it is necessary to delicately adjust the position of the brake pedal depending on the physique of the driver.

Generally, as shown in Fig. 1, a brake pedal C is rotatably supported on a support shaft B of a bracket A attached to the vehicle body, and the brake pedal C is biased upward by a spring. Screw the bolt F into the screw hole E of the protrusion D that is welded to the side, and adjust the position of the bolt F with the lock nut G. The position of the depressed portion H at the tip of the brake pedal C is adjusted by inserting and removing the bolt F.

However, with such a structure, the protruding piece D press-formed into a predetermined shape is attached to the bracket A.
must be welded to a predetermined position, which not only requires time-consuming welding work and increases manufacturing costs, but also causes the tip of the protrusion D to protrude laterally than the brake pedal C. It had some drawbacks, such as sometimes touching your feet.

This invention is an improvement on this in view of the above points, and the embodiments of the invention shown in FIGS. 2 to 4 will be described below.

On the support shaft 2 of the bracket 1 attached to the vehicle body,
A brake pedal 3 is rotatably supported. This bracket 1 is provided with a screw hole 4, into which a threaded rod 5 is screwed. The threaded rod 5 has a large eccentric head 6 at its tip, and the threaded rod 5 can be fixed in the screw hole 4 at a desired position with a lock nut 7. The upper end surface of the brake pedal 3, which is urged upward by a spring, is arranged so as to come into contact with the circumferential surface of the eccentric head 6 at the tip of the threaded rod 5. A depressing portion 8 is connected to the tip of the brake pedal 3, and a brake operation is performed by depressing the brake pedal 3 with the foot against a spring.

An adjusting groove 6b is formed on the top surface 6a of the head 6 along a diameter line.

Next, the effect will be explained.

When the lock nut 7 is loosened and the threaded rod 5 is rotated, the eccentric head 6 can change its position up and down with respect to the threaded rod 5, so the position of the brake pedal 3 can be finely adjusted up and down. Can be done. The threaded rod 5 is inserted into the threaded hole 4 provided in the bracket 1.
Since it is directly screwed into the bracket 1, there is no need to weld a protrusion to the bracket 1. Further, the eccentric head 6 provided at the tip of the threaded rod 5 only needs to be located above the brake pedal 3, and since it does not protrude outward from the brake pedal 3, there is little risk of hitting it with your foot.

As explained above, this invention is a device in which a brake pedal is rotatably supported on a bracket attached to the vehicle body, and a threaded rod having an eccentric head and an adjustment groove on the top surface is attached to the bracket. It is screwed into the provided screw hole, the outer peripheral surface of the eccentric head is brought into contact with the upper edge of the brake pedal, and fixed with a lock nut, and the brake pedal is braked by contacting the outer peripheral surface of the head with the brake pedal. Since the position of the pedal is determined, the position of the brake pedal can be finely adjusted by changing the position of the eccentric head due to the rotation of the threaded rod.Moreover, the rotation of the threaded rod is performed eccentrically toward the front side. Since the adjustment can be done by fitting the tool into the adjustment groove on the head, it can be done easily without being hindered by the frame at all.The threaded rod is directly screwed into the screw hole of the bracket, so there is no protrusion on the bracket. There is no need for welding, which reduces manufacturing costs, and the eccentric head of the threaded rod
It has various effects such as not protruding outward from the brake pedal and reducing the risk of hitting the brake pedal with your foot.
