The fall prevention structure is characterized in that a rotation prevention part 30 for preventing free rotation of the female part 24 is provided between the base plate 2 and the fixing means 20, and a rotation regulating part 40 for restricting a rotation range of a belt 6 is provided between the belt 6 and the fixing means 20.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a belt fall-preventing structure used when a boot is fixed to a board by being applied to a snowboard binding.

FIG. 8 is an explanatory diagram of snowboard binding. As shown in the figure, the snowboard binding 1 includes a base plate 2 that is fixed to the snowboard by screws or the like, a tightening structure 4 for fixing the boot 3 to the base plate 2, and is pivotally supported by the rear portion of the base plate 2 so that it can be folded. A high back 5 that supports the back surface of the boot 3 in the unfolded state is provided, and the boot 3 can be fixed to the snowboard. The tightening structure 4 includes a toe strap 4 a for tightening the toe of the boot 3, an ankle strap 4 b for tightening the ankle of the boot 3, a buckle 4 c, and a belt 6.
The belt 6 is provided between the base plate 2 and the high back 5. The snowboard binding 1 having such a configuration allows the boot 3 and the high back 5 to be integrally tightened by the tightening operation of the ankle strap 4b, thereby enabling comfortable riding.

Conventionally, various snowboard bindings have been proposed.
In the strap for snowboard binding disclosed in Patent Document 1, slits are provided in the longitudinal direction on the belts of the toe strap and the ankle strap, and the tip can be selectively disposed at the closed position or the release position. This prevents the belt from interfering with the boots.
The rear-entry type snowboard binding disclosed in Patent Document 2 includes adjusting means for interlocking the leg support (high back) and the upper element (ankle strap) between the fastening position and the opening position of the boot.

JP2013-530790A Japanese Patent No. 5319537

However, according to Patent Document 1, by providing a slit in the longitudinal direction of the belt, the strength of the belt is lowered, which may cause a problem in safety. In particular, since the belt of the ankle strap is attached to the outer side wall of the base plate (see paragraph number 0022), when the snowboard is attached, the belt does not fall inward and there is little possibility of getting in the way.
According to Patent Document 2, the structure for interlocking the rotational movement of the high back and the ankle strap becomes complicated. In addition, since the rotation axis of the high back and the ankle strap is shared, if any one of them has a problem, either one may be easily affected.
In addition, in the case of a snowboard binding having a structure in which a belt having a tightening structure is provided between the base plate and the high back, the belt sandwiched between the base plate and the high belt is more likely to fall to the base plate side than a belt structure attached to the outside of the base plate. For this reason, it is easy to step on the belt when wearing the boot, and there is a problem that it takes time to attach the strap.

  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, it is an object of the present invention to provide a snowboard binding belt fall prevention structure that does not step on the belt with boots during snowboard binding.

As a first means for solving the above problems, the present invention comprises a belt disposed between a base plate and a high back of a snowboard binding, a male portion and a female portion, and an end portion of the belt can be freely rotated on the base plate. With fixing means to attach,

As a second means for solving the above-mentioned problem, the present invention provides the first means, wherein the rotation preventing portion is
A first fitting portion provided in a through hole of the base plate for inserting the female portion;
An object of the present invention is to provide a snowboard binding belt fall prevention structure characterized by comprising a second fitting portion that is provided in the female portion and fits into the first fitting portion.
According to the second means, the free rotation of the female portion of the fixing means can be prevented, and the rotation area of the belt can be limited.

As a third means for solving the above-mentioned problem, the present invention provides the first or second means, wherein the rotation restricting portion includes a convex portion provided on either the female portion or the belt, It consists of a concave part that fits into the convex part provided on either the female part or the belt,
