Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boot binding device for snowboarding, which is capable of adjusting a position and a posture of a snowboard and mounting boots so as to surely transmit a motion with a predetermined degree of freedom. is there.

[0002]

2. Description of the Related Art In recent years, snowboarding has become widespread as a sporting tool similar to skiing, in which a relatively wide snowboard having a length of about 1 meter is worn to slide down on snow. In the snowboarding, boots having a relatively soft structure must be attached to a proper position of the board at a suitable orientation and angle with respect to the user's posture,
A pair of left and right boot binding devices are used as dedicated fixing fittings for mounting and adjusting the position.

[0003]

However, the boot binding device for snowboarding of this kind is supported by the side plates of the fixing metal fittings while sandwiching the boot positions from both sides, and by the fixing belts connecting the side plates. It has a structure that secures the boots.

Accordingly, since the boot can be mounted within a certain allowable range with respect to the size of the boot, the size of the boot causes a deviation in the fixed position of the boot with respect to the fixing bracket, and as a result, relative to the snowboard. The position will change. Therefore, it is necessary to correct the mounting position of the boot binding device according to the size of the boot, which is very troublesome.

When mounting the boot binding device, not only the distance between the left and right boot binding devices varies depending on the physique and preference of the athlete, but also the horizontal boot attachment angle to the snowboard varies depending on the competition event and the preference of the user. Therefore, correction is required each time. Therefore, especially when wearing a snowboard, it is necessary that these adjustment operations are easy and that quick and reliable adjustment and attachment are possible.

Further, in snowboarding that emphasizes action like in acrobatic competition, it is necessary to accurately transmit the kinetic force from the boots in all directions to the snowboard. The movement of the ankle will be hindered if it is tried to transmit the movement of the ankle, and the movement to the board becomes difficult to try to secure the movement of the ankle, which makes the operability difficult especially for beginners. Therefore, there has been a demand for improvement in the operability of the boot binding device.

SUMMARY OF THE INVENTION The present invention has been made in view of the above demands and has been made in order to solve the drawbacks. Boots of different sizes can be easily attached by adjusting the snowboard to a desired position and a desired angle. SUMMARY OF THE INVENTION An object of the present invention is to provide a snowboarding boot binding device capable of securely holding the boot without impairing motility and reliably transmitting the motion from the boot to the board.

[0008]

A boot binding device for snowboarding according to the present invention has a mounting position on a top surface of a snowboard and a rear end of a base metal member fixed to the mounting position so that an angular position in a rotational direction can be adjusted. A boot binding device for snowboarding comprising a highback leg support member which pivotally attaches a lower end portion so as to be able to move forward and stands up from a snowboard surface to support a rear side surface of a boot for snowboarding along the highback leg. The gist of the present invention is that a heel locking structure composed of a heel hook member or the like is formed on the inner surface of the support member and located on the heel of the snowboarding boot to be mounted.

The heel locking structure composed of the heel hook member or the like can be detachably attached to the high back leg support member. Further, the high-back leg support member has a structure for restricting the maximum rearward-tilt angle by providing the high-back leg support member with a rearward-tilt angle adjusting mechanism.

In addition, in the boot binding device for snowboarding according to the present invention, the lower end portion is forwarded to the rear end of the base metal member fixed to the upper surface of the snowboard so that the mounting position and the angular position in the rotational direction at the mounting position can be adjusted. In a boot binding device for a snowboarding, which is provided with a high-back leg support member that pivots in a tiltable manner and stands upright from the snowboard surface to support the rear side of the snowboarding boot, fixing the base metal member to the snowboard. The means is an engagement of an angle determining gear configured on the side of the base metal and a flat gear configured of a gear rotor fixed on the snowboard side, and an angle determining gear is formed by a base metal levitation means configured between the base metal and the snowboard. Axially displaced with respect to the spur gear to engage or release both gears It is an Abstract that was that structure.

[0011]

In the above snowboarding binding device, the upper part of the heel of the boot is locked by the heel locking structure such as a heel hook member provided on the high-back leg support member to prevent the boot from coming off in the floating direction. Therefore, the snowboard accurately follows the movement of the boot in the jump-type action.

Further, by providing a one-touch rearward tilting angle adjusting mechanism, it is possible to easily adjust and change the maximum rearward tilting angle of the high-back leg support member, and the optimum angle according to the contents of the snowboarding competition can be set. It can be finely adjusted.

Furthermore, the rotation direction angle adjusting and fixing means of the base metal fitting to the snowboard of the boot binding device for snowboarding according to the present invention meshes the base metal fitting with the gear rotor fixed to the snowboard side via the base metal fitting floating means. Alternatively, the structure is such that it can be slidably displaced to the release position. Therefore, the horizontal mounting angle of the binding device to the snowboard can be quickly changed even during the competition.
