DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is, in the case of a sports gliding on snow riding on one plate (so-called snowboard), are those related to the so-called binding is an instrument for securing a dedicated boots to the snowboard .

[0002]

2. Description of the Related Art Conventionally, a binding attached to a snowboard has been adjusted such that the direction of a foot fixed by the binding is oblique to the longitudinal direction of the snowboard. There is no rule on the direction of the foot, and it is up to the person to turn right or left with respect to the front of the snowboard, and the angle at which the snowboard is inclined is also free. The binding is attached directly to the snowboard with a screw or the like, and the angle of the binding attached to the snowboard is fixed. There is no other choice but to change. Because the binding is a tool for integrating the sliding snowboard with the operator's foot, the operator shifts the center of gravity during the sliding and tilts the snowboard left and right. This is to prevent the snowboard from easily detaching.

[0003]

However, if the foot is fixed at an angle to the direction of the foot when using the snowboard, that is, obliquely to the longitudinal direction of the snowboard,
Even if you do not slide on the snow, you are facing diagonally, so even if you release one foot, the snowboard is facing diagonally, making it difficult to walk. Therefore, in general, the user walks while making the back foot free and the front foot slightly inward, and sliding the snowboard in the traveling direction.
Also, in the state of riding on the lift, that is, in the state where the lower part hangs down from the knee, since the foot fixed by the binding naturally faces forward, the longitudinal direction of the snowboard is oblique to the direction of the foot. . Therefore, when multiple people ride together like a pair lift or triple lift, if the snowboard of the passenger is fixed in the opposite direction, or if it is a normal skier,
They often feel uncomfortable when they come in contact with snowboards or skis.

[0004] Further, the degree of inclination of the snowboard with respect to the longitudinal direction may be slightly changed depending on the condition of the slope to be slid, and each time the binding is detached from the snowboard and re-attached. .
Also, as described above, it is up to the person to turn right or left with respect to the front of the snowboard, but it is not possible to enjoy other types of snowboarding with conventional snowboarding, especially at rental shops, after binding. There is also a problem that it is very complicated.

The present invention has been made in view of the above points, and has been made to be able to rotate in a horizontal direction while being attached to a snowboard.
And to provide a <br/> Dinh grayed which facilitates the angular adjustment with respect to the longitudinal direction of the snowboard.

Hereinafter, the binding 1 will be described. As shown in FIG. 2, the binding 1 includes a binding body 10 to which a special boot for snowboard can be fixed. The binding body 10 is fastened to the snowboard 3 by an adjusting body 11 that comes into contact with the snowboard 3 and a screw. With the fixing member 12. Buckles 4 and 5 are provided on the binding body 10 so that a boot (not shown) can be fixed.

As shown in FIG. 3, the surface of the adjusting body 11 has an annular band shape, and a hole 13 through which the fixing member 12 can pass is provided at the center. A large-diameter portion (engagement region) 1 having a predetermined width from the outer periphery of the annular belt-shaped surface of the adjusting body 11.
4 is slightly thicker, a small diameter portion (fixing region) 15 having a predetermined width from the inner circumference is provided relatively thin, and a middle diameter portion (sliding region) having an intermediate thickness is provided between the two. 16 are provided.

Of these, a half circumference (180 °) of the large diameter portion 14
Is provided with a tooth-shaped engaging portion 17 which is continuous in the circumferential direction, and the teeth of the engaging portion 17 are provided so that the angle changes by 7 ° per pitch. A plurality of circular display portions 18 are provided at the same pitch as the above-described engagement portions 17 on the half circumference (180 °) on the opposite side of the engagement portions 17. The angle with respect to 11 is displayed as a mark. The small diameter portion 15 is provided with four locking grooves 19. The locking groove 19 is provided with a locking projection 20 of the fixing member 12.
Can be locked so that when the fixing member 12 is fixed to the snowboard 3, the adjusting body 11 does not rotate in the circumferential direction. The locking groove 19 is formed in a gear shape by continuously forming a V-shaped groove in the circumferential direction.
The peaks and valleys of the gear change at an angle of 5 ° per pitch. Naturally, the locking projection 20 is formed in a similar gear shape. By slightly moving the pitch, it is possible to adjust a delicate angle when fixing the adjusting body 11.

On the other hand, the middle diameter portion 16 is
0 constitutes a plane that can slide in the circumferential direction, and this surface and the lower surface of the binding body 10 come into contact with each other. A regulating groove 24 is provided in the middle diameter portion 16, and a projection 25 (FIG. 4) at a lower portion of the binding body 10 fits into the regulating groove 24 to regulate the rotation range of the binding body 10. It has become. The desired position of the restriction groove 24, for example, “I” of the display unit 18
The rotation of the binding body 10 can be restricted at a desired position by screwing the stopper 24a to the side of the binding 24. This stopper 24a is located at an arbitrary position in the regulating groove 24,
For example, it can be changed to the side of "A" and "B".

In this way, the binding body 10
The upper member is prevented from being detached upward by the fixing member 12 and slides and rotates on the adjusting body 11. This sliding rotation is performed along a rotation direction about the fixed member 12 as a central axis. This rotation changes the angle of the binding body 10 with respect to the adjustment body 11 fixed to the snowboard 3.

Next, positioning of the binding body 10 will be described. A positioning member 21 is provided on the binding body 10 so as to be vertically movable. The positioning member 21 has a distal end portion 22 that engages with the tooth-shaped engagement portion 17 provided on the large-diameter portion 14. Have. The positioning member 21 is urged downward by a spring 23, and is always forced in a direction in which the positioning member 21 engages with the engagement portion 17 at the time of normal operation, that is, when angle adjustment is unnecessary. As a result, the binding main body 10 cannot slide in the circumferential direction, and as a result, is firmly fixed.

Next, the operation of this embodiment having the above-described configuration will be described. First, as shown in FIGS. 4 and 5, when adjusting the angle of the binding main body 10, the positioning member 21 is pulled upward by the hooking ring 21 a against the force of the spring 23, and the positioning member 21 is separated from the distal end portion 22 of the positioning member 21. The engagement with the engagement portion 17 is released. Next, the binding body 1
0 is slid and rotated on the middle diameter portion 16 of the adjustment body 11 to bring the binding body 10 to a predetermined position on the adjustment body 11. Next, when the tension ring 21 is released, the positioning member 21 is lowered by the force of the spring 23, and the distal end portion 22 of the positioning member 21 is engaged with the engaging portion 17 of the large diameter portion 14, thereby fixing the position of the binding body. Is done.

At this time, the display unit 1 provided on the adjusting body 11
8 is visually recognized by a through hole 18 a provided in the binding body 10. For example, "e" is displayed as the display unit 18,
When viewed through the through hole 18a, the rotational position angle of the binding body 10 can be confirmed as "e".

It goes without saying that various embodiments can be adopted without departing from the spirit of the present invention .

[0018]

As described above, according to the present invention, by fixing the fixing member to the snowboard, the small diameter portion of the adjusting body locked by the locking projection of the fixing member can be fixedly mounted. Further, the binding body having the annular sliding surface can be slid between the fixing member and the adjusting body, but can slide on the surface of the middle diameter portion of the adjusting body, and the fixing member penetrates the binding body. Since the binding body is fixed to the snowboard in such a state, the binding body can rotate in the horizontal direction around the fixing member while sliding on the middle diameter portion of the adjustment body, and the angle of the binding body with respect to the longitudinal direction of the snowboard can be adjusted. Becomes The positioning member incorporated in the binding body is engaged with the engaging portion of the adjustment body to limit the sliding of the binding body in the circumferential direction with respect to the adjustment body fixedly mounted on the snowboard. As a result, the angle of the binding main body can be determined. Therefore, the angle adjustment state and the angle determination state can be operated only by adjusting the engagement state of the positioning member with the engagement portion, which is very simple.
