JP2000070432A - Rotating device of snowboard binding - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a rotating device of snowboard binding, which has higher safety and usability, and gives various sliding style. SOLUTION: This rotating device is designed in such a manner that balls housed in between a top plate 4 and a bottom plate are cramped by a center shaft and top and bottom rings 9.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turning device for turning a fixed type binding used for snowboards freely.

[0002]

2. Description of the Related Art A conventional binding has a fixed angle on a snowboard, has no function of rotating, and has both legs fixed to the snowboard. Therefore, the impact at the time of falling was large, and there was a problem in safety and operability. Japanese Patent Application Laid-Open No. Hei 9-276474, entitled "Snowboard mounting bracket" Claims "A foot support plate is provided on the top of the ceiling plate, belts are provided on both sides of the foot support plate, and the wrapping is carried out in a green sliding plate. There is a mounting bracket for snowboards that contains a top plate and a sliding plate mounted on the board. In the conventional invention, 1) the cross-sectional view of the turntable of FIG. 1 is a view in which a dish-shaped body is turned down, which impairs the rotation function due to the weight.
2) In the structure of the sliding plate with green color, snow, water, and dust are invaded and the rotation function is impaired. Therefore, in the prior art, the rotation state becomes unstable and the effect cannot be obtained.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an exercise apparatus which is excellent in safety and operability and which has not been hitherto known, except for the drawbacks of the conventional fixed type binding.

[0004]

A plurality of balls held by a retainer are sandwiched between a top plate and a bottom plate, and the top plate and the bottom plate are rotatable by a center axis and receiving rings above and below the center axis. It is characterized in that a seal is provided while holding a slight gap in the inside where the peripheral walls of the top plate and the bottom plate overlap with each other.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of an entire snowboard, (1) is a snowboard, (2) is a rotating device, and (3).
Is a binding provided on the upper part. FIG.
The top plate (4) and the bottom plate (5) of the rotation device (2) are shown, and the ball (6) accommodated therein and the top plate and the bottom plate, which are retainers (7) for holding the ball, are penetrated. Central axis (8)
And a center ring upper and lower receiving ring (9) sandwiched between the top plate and the bottom plate so as to be rotatable. (10)
(10 ′) is a hand hole formed in the top plate and the retainer for fixing the bottom plate of the rotating device to the snowboard, (1).
1) is a seal provided inside the outer peripheral wall where the outer peripheral wall overlaps. This peripheral wall is for increasing the strength of the plate and providing a seal. The seal is intended to keep the inside of the rotating device clean. The present invention has the above configuration.
When using the present invention, the bottom plate is fixed to the snowboard, the binding is fixed to the top plate, and if the feet are fixed to the binding that is rotatable by the action of the ball, each of the left and right feet will have a central axis. It is possible to rotate at any angle around the center, and with respect to the longitudinal direction of the snowboard,
The foot can be operated at any angle. FIG.
Shows another example of a rotating device, (4) is a top plate, (5) is a bottom plate, (8) is a central axis, (9) is a receiving ring, (10) (1)
0 ') is a hand hole opened in the top plate and sliding material, (1)
1) is a seal, and (12) and (12 ') are sliding materials contained on the inner surface of the top plate and the bottom plate. The rotating device can rotate by the sliding action of the sliding surface (13) of the sliding member. The rotating device has a simpler structure than the rotating device of FIG.
This has the same effect as the ball (6). The present invention can take the following embodiments. (1) The type of seal described in FIG. 2 is not limited. (2) The type of sliding material described in FIG. 3 is not limited.

[0006]

According to the present invention, as shown in the embodiments,
By installing the binding in a device that can rotate freely, the direction of the foot can be freely changed according to the sliding situation, which is effective for safety and operability when falling, and the direction of the rotation device The freedom of sex allows the player to change directions freely, enjoy a change in the sliding style on a slope, and provide a sporting effect that is not available on conventional snowboards.

Claims (2)

[Claims] A plurality of balls (6) held by a retainer (7) are sandwiched between a top plate (4) and a bottom plate (5),
The center plate (8) penetrating the top plate and the bottom plate and the receiving ring (9) above and below the center axis sandwich the top plate and the bottom plate so as to be rotatable, and the peripheral walls of the top plate and the bottom plate overlap. A binding rotation device for a snowboard, wherein a seal (11) is provided with a slight gap inside. 2. The swinging device according to claim 1, wherein a sliding member is provided inside the top plate (4) and the bottom plate (5).
