Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front hawk protector for a motorcycle.

[0002]

2. Description of the Related Art A front hawk of a motorcycle has an upright type in which an outer tube is slidably inserted under the left and right inner tubes so as to be cushioned. There is an inverted type that inserts so that the inner tube can slide and cushion. And
Since the outer peripheral surface of the inner tube is a sliding surface, it will be unsatisfactory if it is damaged by flying stones. Therefore, in the upright type, a boot having a bellows shape is attached between the upper end of the outer tube and the under bracket of the front hawk to cover the lower part of the inner tube.

[0003]

Since the boot covers the entire outer circumference of the inner tube, the forks become thick, the intervals between the left and right forks become wide, and the front forks become large and heavy. In addition, there is a problem that the boot is deteriorated by use and may be torn.

In view of the above point, the present invention is an upright front hawk, and a protector can be attached to the front side of the sliding surface of the left and right inner tubes to protect it from flying stones, which has high durability. The purpose of the present invention is to obtain a front hawk protector for a motorcycle that can reduce the width of the front hawk in a narrow width.

[0005]

In order to achieve the above object, a front hawk protector for a motorcycle according to the present invention comprises:
With the upright front fork inserted so that the outer tube slides under the left and right inner tubes so that it can be cushioned, the lower end of the protector that covers the lower front half of the inner tube is fastened to the upper front side of the outer tube, A C-shaped guide piece is attached to the inside of the lower part of the front cover or the number plate attached to the upper front side of the left and right inner tubes, and the upper part of the protector is slidably inserted into the guide piece.

[0006]

The protector covers the front side of the sliding surface of the lower portion of the inner tube and can protect the inner tube from flying stones. And the protector is
It can be made durable with a synthetic resin plate, etc., and it can be moved together with the expansion and contraction cushion of the outer tube, and the upper part can be touched and stopped by the guide piece. Also, the protector can be set so as not to protrude inside and outside, and the width of the front hawk can be made narrow and lightweight.

[0007]

Embodiments of the present invention will be described below with reference to FIGS. Front hawk 1 is a left and right inner tube 2
The upper part of the is attached to the front end of the frame 4 by the upper and lower brackets 3 so as to be rotatable,
It is an upright type in which the left and right outer tubes 5 are slidably inserted so as to be able to expand and contract, and both ends of an axle 7 rotatably supporting a front wheel 6 are fastened to the lower portions of the left and right outer tubes 5. On the upper front side of the left and right inner tubes 2,
When traveling on a general road, the front cover 8 to which headlamps and the like are attached is attached. When racing or the like, the front cover 8 is removed and the number plate 9 is changed.

The protector 10 is made of a synthetic resin or the like in a vertically long shape. The lower part of the protector 10 is fastened to the upper part of the outer tube 5 with bolts 11 to cover the lower front side of the inner tube 2. Then, a guide piece 12 bent in a C shape is attached to the inside of the lower portion of the front cover 8 or the number plate 9. The front cover 8 and the number plate 9 are formed by molding using a synthetic resin, and the guide piece 12 may be integrally formed with the front cover 8 and the number plate 9. Protector 10
Moves together with the expansion and contraction cushion of the outer tube 5, and inserts the upper portion of the protector 10 into the guide piece 12 to prevent steadying.

[0009]

As described above, since the present invention is configured as described above, the protector 10 can cover the front side of the lower sliding surface of the inner tube 2, and the inner tube 2 can be stepped on by flying stones or the like. Can be protected from The protector 10 can be made of a durable material such as synthetic resin, and can be easily attached and detached to facilitate maintenance of the front fork 1. Also, front hawk 1
The width can be made narrower and the weight can be reduced. Then, the front cover 8 or the guide piece 12 of the number plate 9 can prevent the upper portion of the protector 10 from steadying.
