Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snowboard shoe fixing device.

[0002]

2. Description of the Related Art A snowboard shoe fixing device (hereinafter sometimes simply referred to as "binding") is mounted at a predetermined angle with respect to the longitudinal direction of the snowboard as shown in FIG. Thus, the binding 12 on the board 120
By wearing 2, the user can glide on the snow surface like surfing. The angle of binding to the snowboard should be set to suit the user's preference. Conventionally, as shown in FIGS. 10 and 11, a fixing member 102 in which a plurality of convex portions 100 are formed at a constant pitch in the circumferential direction on a disk-shaped outer peripheral edge, and the convex portion 1
A plurality of recesses 104 that are locked to 00 are formed on the inner peripheral edge,
There is a binding including a clamped portion 108 that is clamped between a fixing member 102 and a board 106, and a fastener mounting member 110 that is formed so that a fastener for fixing a shoe can be attached. According to this, first, the fastener mounting member 110 is adjusted to a desired angle with respect to the board 106,
The convex portion 100 of the fixing member 102 is superposed so as to fit into the concave portion 104 of the fastener mounting member 110. At this time, the fixing member 102 is overlapped so that the female screw 112 inserted into the board 106 corresponds to the screw hole of the fixing member 102. Next, bolts 116 (four pieces) are passed through the screw holes 114 of the fixing member 102, and the bolts 116 are tightened to the female screw 112 of the board 106. That is, the fixing member 102 and the fastener mounting member 110 are simultaneously mounted on the board 10.
Fix to 6. Thereby, the fastener mounting member 110 can be fixed to the board 106 at a desired angle.
A plurality of internal threads 112 are arranged in a row in the length direction of the board 106 at predetermined intervals, and the position of the binding with respect to the board 106 in the length direction can be adjusted at predetermined intervals.

[0003]

However, with the above-mentioned structure, only the angular position of the fastener mounting member 110 in the rotational direction and the position of the board in the front-rear direction can be adjusted. There is a problem in that the positions of the front-rear direction, the left-right direction, the front-back inclination, and the left-right inclination cannot be adjusted based on the shoe orientation. Further, as described above, the front and rear position adjustment can be performed only at predetermined intervals, and fine adjustment cannot be performed. The mounting position of the snowboard shoe varies depending on the user and the content of the competition used, and it is required to be able to make fine adjustments in all directions, but this cannot be met. There is also a problem that once the fastener mounting member 110 is fixed to the board 106, the angle cannot be easily changed. In other words, the four bolts 116 must be detached when the binding is mounted on the board 106 or when only the angle of the fastener mounting member 110 is adjusted. Furthermore, the binding of the snowboard is subjected to a very strong impact force, and it must be securely fixed so as not to come off due to the force.

Therefore, an object of the present invention is to fix the position of a fastener for fixing the shoe (hereinafter referred to as "shoe fixing fastener") easily and surely in a desired direction. To provide a device.
