Abstract

PURPOSE:To obtain a prop stand installation device for a motorcycle in which a stand bracket can be installed immediately outside a rear fork and the projection quantity to the side can be reduced, in the constitution in which the stand bracket of a prop stand is tightened on the front part side surface of the rear fork. CONSTITUTION:The front parts of the forks of the left and right pipe members made of light allay are welded on the left and right rear part side surfaces of a rear fork body 1 casted using a light allay, and a boss 4 having a tapped hole 5 is projectingly installed on the rear part side surface on one side of rear fork body 1, and projected from a window hole formed at the front part of the fork 2 on one side and welded, and the stand bracket 9 of a prop stand 7 is tightened into the tapped hole 5 on the boss 4 by a bolt 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prop stand mounting device for a motorcycle.

[0002]

2. Description of the Related Art In a motorcycle, a stand bracket is attached to a lower end on one side of a frame, and a prop stand is attached to the stand bracket so that the prop stand can be raised and lowered.
The prop stand is designed to support the vehicle. In this case, since the stand bracket is attached to the lower end of the frame, the minimum ground clearance becomes low, which is not preferable for an off-road motorcycle traveling on a bad road.

In an off-road motorcycle, a nut fitting is welded to one front part of a rear fork, and a stand bracket of a prop stand is fastened to the nut fitting with a bolt.

[0004]

When the stand bracket is fastened to the front side surface of the rear fork, the mounting position becomes higher and the minimum ground clearance can be increased. However, since the nut bracket is welded to the front side surface of the rear fork, the stand bracket is attached to the rear fork by protruding by the thickness of the nut bracket, which may be convenient for the rider to catch a sponge. bad.

In view of this point, the present invention tightens the stand bracket of the prop stand on the front side surface of the rear fork, and the stand bracket can be attached to the outer side of the rear fork, and the amount of lateral projection. An object of the present invention is to obtain a prop stand mounting device for a motorcycle capable of reducing the size.

[0006]

In order to achieve the above object, a prop stand mounting device for a motorcycle according to the present invention is a front fork of a light alloy pipe material on the left and right rear side of a rear fork body cast from a light alloy. The boss is provided with a screw hole on the rear side surface of one side of the rear hawk body, and the boss is welded by protruding from the window hole drilled in the front part of the hawk on one side. It is because it was fastened to the screw hole of the boss with a bolt.

[0007]

[Function] The boss projecting on the rear hawk body can have screw holes carved inward from the outer surface of the hawk, and the portion of the boss projecting from the outer surface of the hawk can be used only as a welding margin. It can be mounted close to. Therefore, the amount of lateral protrusion of the stand bracket can be reduced.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The rear hawk is formed by casting the front rear hawk body 1 using a light alloy, and welding the front insides of the left and right hawks 2 of the light alloy pipe material to the left and right rear side surfaces of the rear hawk body 1. I am doing it. Rear Hawk Body 1
The boss 4 is integrally formed at the portion of the meat-thickening portion 3 on the rear side surface on one side of the above so as to project laterally. Then, screw holes 5 are formed in front of and behind the boss 4. At the front of the hawk 2 on one side, the boss 4
The window hole 6 is formed in advance according to the position, and the tip of the boss 4 is projected from the window hole 6 and welded to the hawk 2.

The prop stand 7 has a support shaft 8 at its base end.
The stand bracket 9 is pivotally attached to the stand bracket 9 and the spring 10 is provided inside between the stand bracket 9 and the prop stand 7.
The prop stand 7 can be erected downward, and can be swung backward to rotate the prop stand 7.
It is held at 0. Then, the stand bracket 9 is attached to the screw hole 5 with the bolt 11 in alignment with the tip surface of the boss 4.

The boss 4 is provided so as to project from the rear hawk body 1, and the screw hole 5 can be formed on the inside of the outer surface of the hawk 2. Therefore, the stand bracket 9 can be mounted close to the outer surface of the hawk 2,
The amount of protrusion from the hawk 2 to the side can be reduced.

[0011]

As described above, since the present invention is constructed as described above, the stand bracket of the prop stand can be attached in the vicinity of the side surface of the rear fork, and the prop bracket can be projected to the outside of the stand bracket. Fewer riders can catch less pants.
Also, since the stand bracket is attached to the rear fork, the ground clearance can be increased. Since the boss of the screw hole is formed integrally with the rear hawk body, the number of parts can be reduced and the cost can be reduced.
