Abstract

PROBLEM TO BE SOLVED: To prevent skidding by a method wherein the undersurface of a board is so formed to be convex across the length thereof and edges are formed sticking on both side rims of the undersurface of the board to accomplish an edging operation simply while improving linearly gliding performance. SOLUTION: The undersurface of a board 1 with a top part 11 thereof warped is so formed to be convex across the width thereof excluding the top part 11 thereof. Moreover, edges 12 are formed sticking on both side rims occupying the most part of a gliding surface on the undersurface of the board 1. As the board 1 has a convex undersurface and sticking edges 12, as compared with the board having a flat surface, glidability and straight running performance are improved thereby eliminating accidental skidding. The edges 12 can work easily by a slight shifting of the physical weight thereby enabling handling of the board simply in turning, traversing and the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snowboard on which a rider stands and glides on a snow surface.

[0002]

2. Description of the Related Art A conventional snowboard consists of a flat board with a slightly raised top, and the rider stands up with his shoes tied to a holder on the board and slides on the snow surface. I am trying.

[0003]

The problem to be solved is that the sliding surface of the snowboard is flat, so if the weight shifts and the edge is tilted to move the edge, it is necessary to make the edge. No, it is a child that requires skill.

Further, since the sliding surface of the snowboard is flat, the sliding performance is poor when going straight, and if the board is not tilted to reach the edge, it will skid.

[0005]

According to the present invention, an edge can be easily marked when a turn or a slope is descending, and the sliding property is excellent when going straight, and careless skidding can be prevented. In order to do so, the lower surface of the board is formed to have a convex shape in the width direction, and edges are formed so as to project from both side edges of the lower surface of the board.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A snowboard according to the present invention, as shown in FIGS. 1 to 5, is a board 1 in which a top portion 11 is raised, and a portion of the lower surface of the board 1 excluding the top portion 11 is widthwise. The board 12 is formed in a convex shape, and the edges 12 are formed so as to project on both side edges that occupy most of the sliding surface on the lower surface of the board 1.

In the snowboard thus constructed, the lower surface of the board 1 has a convex shape, and the edges 12 are formed so as to project from both side edges, so that the lower surface simply has a flat shape. Compared with other types, it has better gliding and straight running characteristics, and inadvertent side slip is effectively prevented.

[0008] In addition, edge 1 is caused by a slight weight shift.
2 can be easily pushed, and the operation of the board 1 at the time of turn or downhill can be easily performed.

FIGS. 6 to 8 show another embodiment of the present invention. In this case, the handle 2 is mounted on the board 1.

As shown in FIGS. 9 and 10, the handle 2 has a holding portion 21 attached to the board 1 by a plurality of screws 3, and a tilting pin 21 in the holding portion 21 in the front-back direction. It is composed of a bar-shaped handle body 22 that is held as much as possible.

Then, as shown in FIG. 11, the pivot pin 4
A click mechanism 5 is provided between the holding portion 21 and the grip body 22 in the lower part of the click mechanism 5.
The grip body 22 is positioned with respect to the holding portion 21, and when the grip body 22 is applied with a force larger than a predetermined value, the click is released and the grip is tilted in the front-back direction. .

The click mechanism 5 includes a holding portion 21.
Click holes 6 are formed in the corresponding portions of both side walls of the holder, and click balls 9 are provided at both ends of the cylinder 7 fixed to the lower portion of the handle body 22 via springs 8. The balls 9 are fitted in the click holes 6, respectively.

Further, here, as shown in FIG. 9, a plurality of click holes 6 are provided so that the positioning can be adjusted stepwise when the handle body 22 is tilted.

In the snowboard thus constructed,
When the rider stands on the board 1 and glides on the snow surface, the rider can grasp the grip portion of the handle 2 for easier balance, and the lower surface of the board 1 described above has a convex shape. The operability of the board 1 is further improved due to the fact that the edges 12 are formed so as to project on both side edges.

Further, when an excessive force is applied to the handle body 22 at the time of falling, it is effective that the handle body 22 tilts in the front-rear direction and the handle body 22 gives a bruise to the rider. Can be prevented.

Further, here, the upper surface of the board 1 is made to have a large frictional resistance. Specifically, for example, as shown in FIG. 6 and FIG. 7, a rubber sheet 10 having an uneven surface is attached to the portion of the upper surface of the board 1 on which the rider stands.

As described above, by making the upper surface of the board 1 a surface having a large frictional resistance, the rider's shoes are not fixedly tied on the board 1 and can stand freely without being bound on the board 1. You will be able to ride. Therefore, it is possible to get on the board 1 in an optimum state depending on the running condition, in combination with the fact that the handle 2 can be held to balance.

[0018]

As described above, in the snowboard according to the present invention,
The bottom surface of the board is formed to have a convex shape in the width direction, and the edges are formed so as to protrude from both side edges of the bottom surface of the board, so that the edges can be easily marked when turning or when descending. In addition to being able to do so, it has an advantage that it is excellent in gliding property when going straight, and inadvertent side slip can be prevented.
