Description

[Detailed Description of the Invention] Fields Related to the Invention The present invention relates to a shock absorber suitable for a race course, a test course, a go-kart course, etc. of an automobile.

BACKGROUND ART Generally, shock absorbers provided on go-kart courses include
Although old tires are used, it is difficult to obtain a sufficient cushioning effect due to the shape and hardness of the old tires, and the old tires lack compatibility with the atmosphere of the course.

Further, Japanese Utility Model Laid-Open No. 57-202412 discloses a buffer stop for traveling vehicles, etc., but in this buffer stop, when it rains, the rain is released from the vent hole formed in the end face to the inside. As it flows and accumulates, and the buffer function cannot be expected,
A large number of vent holes are required, which affects the appearance and finish.

Problem of the Invention The problem of the invention is to prevent rainwater from entering inside, improve the cushioning effect by reducing the size and weight, and make the cushioning effect easily adaptable to use.
The purpose is to provide shock absorbers that are adapted to the atmosphere of the course and suitable for outdoor installation.

DESCRIPTION OF SPECIFIC EMBODIMENTS In the following, the shock absorber of the present invention will be explained based on the specified and illustrated specific examples. FIGS. 1 and 2 are adapted to be used for a go-kart course. A specific example 10 of the shock absorber of the present invention is shown, and the shock absorber 10
In the block-shaped hollow skin 11, the air escape hole 18 opened in the upper portion of the end wall 17, and the upper end above the air escape hole 18 so as to cover the air escape hole 18, the lower end thereof. Each of them is positioned below the air escape hole 18, and its lower end is opened, and a drainer cover 19 that is joined to the outer surface of the end wall 17 in a substantially inverted U shape is provided. Molded and also cushioning padding 12
However, it is packed in the hollow outer skin 11 in consideration of the cushioning effect and the shape recovery speed.

In particular, the hollow skin 11 includes a skin body 13 composed of a top wall 15, a pair of side walls 16, and a pair of end walls 17, and the skin body thereof.
Bottom wall sheet fused to the opening edge of 13 with high frequency welder 14
Composed of and. Of course, the bottom wall sheet 14 is fused to the opening edge of the skin body 13 after the padding 12 is packed in the skin body 13.

Further, the drain cover 19 covers the air escape hole 18 and extends its lower end to a position below the end wall 17, and the lower end is opened to be fused to the end wall 17 of the skin body 13, The rainwater is prevented from entering the inside through the air escape hole 18, and the air that escapes from the air escape hole 18 to the outside is resisted.

Therefore, in use, the shock absorber 10 is stabilized in the installed state by the bottom wall sheet 14, and at the time of a collision,
Along with the venting of the air, an excellent cushioning effect is exhibited. Further, since the air passage that is suddenly folded back for the air toward the air escape hole 18 is formed by the drain cover 19, during raining, rainwater is separated from the air at the sharp folding back of the air passage. Then, the rainwater is prevented from invading the inside of the shock absorber 10, and the cushioning effect is secured.

As will be apparent from the specific embodiments of the invention described above with reference to the drawings, for one of ordinary skill in the art to which the invention pertains, the contents of the invention will It derives from the nature and substance of the invention and is readily embodied in another aspect where it is objectively recognized that they are inherent. Of course, the content of the device is commensurate with the subject of the device and is essential for the implementation of the device.

Benefits of the Invention As can be understood from the above, the shock absorber of the present invention has an air escape hole opened in an upper portion of the end wall, and an upper end of the air escape hole above the air escape hole so as to cover the air escape hole. , A block-shaped hollow skin having a draining cover whose lower end is located below the air escape hole, and whose lower end is opened and whose periphery is joined to the outer surface of the end wall in a substantially inverted U shape. And the cushioning padding that is packed in the hollow skin, the cushioning device of the present invention can be made smaller and lighter, and the cushioning effect can be improved with air release, and when raining, rainwater Is prevented from invading the inside of the body, and its cushioning effect is secured, and the cushioning effect can be easily adapted for use, the cushioning effect is improved, and the safety of the human body in the event of a collision is improved. It is secured and also adaptable to the atmosphere of the course and adapted for outdoor installations, so that it is very useful and practical for cars on race courses, test courses, or go-karts.
