Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a footrest adjusting device for a motorcycle.

[Prior Art] In a motorcycle, a rider sits astride a seat provided on an upper part of a vehicle body, and left and right feet are placed on footrests provided so as to project to left and right lower parts of the vehicle body for driving.
Further, the footrest has a base shaft fastened to a long hole of a bracket of a vehicle body by using a nut so that the footrest can be fastened by adjusting the position along the long hole according to the rider's physique.
There is also a plate-shaped footrest that can be adjusted along the screw axis. See, for example, Japanese Utility Model Laid-Open No. 61-58183.

[Problems to be solved by the device]

However, in the above-mentioned conventional example where the footrest is fastened with a nut, the footrest may be
Since the total weight of the rider may be added and the load to be received is large, it is necessary to firmly tighten with a large nut, and with a small spanner on a motorcycle hand tool, sufficient tightening torque cannot be obtained, Since it is tightened with a large wrench with a large tightening torque at a repair shop, there is an inconvenience that it cannot be adjusted at any time. The latter of the conventional techniques is suitable for passengers whose footrests are plate-shaped, but is unsuitable for rider footrests.

The present invention has been made in view of such a point, and it is possible to obtain a convenient motorcycle footrest adjustment device that can tighten the footrest with a strong tightening torque without a tool and can be adjusted in position at any time without loosening. To aim.

[Means for Solving the Problems]

In order to achieve the above object, a motorcycle footrest adjusting device according to the present invention has a slider slidably inserted into a long hole provided in a bracket attached to a vehicle body, and a base of the footrest is pivotally moved upward at a tip end thereof. The attached base is slidably and non-rotatably inserted into the lateral hole provided in the slider, the leaf spring is sandwiched at the inner end, the lock screw is screwed, and the worm shaft is engaged with the gear provided on the outer periphery of the lock screw. This is because the knob provided at the end of the worm shaft is fitted with the stopper provided at the footrest to fix the knob in the rotation direction.

[Action]

The knob can be turned by hand by rotating the footrest upward and removing the stopper from the knob. When the knob rotates the worm shaft to loosen the lock screw, the leaf spring that tightens the slider loosens, and the slider can slide along the long hole of the bracket, and the footrest position can be adjusted to the rider's physique. Then, the slider is fixed in the reverse order. Even if the knob of the worm shaft is turned by hand, the worm and gear mesh with each other to increase the boosting force, and a large tightening torque can be applied to the lock screw for reliable tightening. At the position where the rider uses the footrest, the stopper is fitted into the knob and the knob does not rotate, so the lock screw does not loosen.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Car body 1
A long hole 3 is provided in a bracket 2 that is fastened to the slider 2, and a slider 5 having a flange 4 on the outer side is slidably inserted into the long hole 3. The footrest 6 has a rod-like shape that projects laterally, and the base end is a horizontal axis 7
It is pivotally attached to the tip of the base shaft 8 so that it can be rotated upwards by.
A foot petal 9 is rotatably supported on the base shaft 8 and is slidably and non-rotatably inserted into a square hole 10 provided in the slider 5. A leaf spring 11 for pressing the slider 5 against the bracket 2 is inserted into the inner end of the base shaft 8 and a lock screw 12 is screwed therein. A gear 13 is engraved on the outer periphery of the lock screw 12 to engage a worm shaft 14 axially attached to the slider 5. A knob 15 is provided at the end of the worm shaft 14, and a stopper 16 protruding from the footrest 6 is fitted in a groove 17 provided on the outer circumference of the knob 15.

In the above configuration, the rider sits astride the seat 18 provided on the upper portion of the vehicle body 1, places his left and right feet on the left and right footrests 6, and operates the foot petal 9 with his toes.

Adjust the slider 5 to the appropriate position in the slot 3 and use the knob 15
When the worm shaft 14 is rotated with, the lock screw 12 is tightened, and the slider 5 is strongly tightened to the bracket 2 with the leaf spring 11. Even if the knob 15 is turned by hand, the worm shaft 14 has a large worm power, and the lock screw 12 can be tightened with a large tightening torque. The knob 15 can be stopped by the stopper 16.

[Effect of device]

As described above, since the present invention is configured as described above, a large boost can be obtained with the worm shaft, and the position of the footrest can be manually adjusted at any time according to the physique of the rider. And the knob of the worm shaft is
It can be stopped with a stopper and will not loosen. Also, since a large boost can be obtained with the worm shaft, the parts can be made compact and small.
