Abstract

PROBLEM TO BE SOLVED: To enable a base plate to bend with its longitudinal axis as a center by arranging the bottom plate part of a base plate to be more elastic than both wall parts, freely bend with elasticity around the longitudinal axis and have stiffness in the direction along the longitudinal axis. SOLUTION: A heel cup which connects the back of both wall parts 1a and 1b of a base plate 1 with a channel section is not attached. The wall parts 1a and 1b are formed of a stiff material such as aluminum. The bottom plate part 1d of the base plate 1 is formed of an elastic plastic material. These arrangements make the bottom plate part 1d of the base plate 1 capable of bending around its longitudinal axis and absorbing shocks during gliding. In addition enough stiffness provided for both wall parts 1a and 1b prevents the bending in the direction of the longitudinal axis.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art FIG. 3 is an explanatory view of a conventional snowboard binding, in which a base plate having a channel-shaped cross section is fixed to a snowboard body (not shown).
1a and 1b are side wall portions thereof, 1c are both side wall portions 1a,
1a is a heel cup that connects the rear parts of the boots to each other, 2 is a highback provided at the rear end of the base plate 1 so as to be in contact with the rear surface of the boot 3, and 4 is a highback cushion attached to the inner surface of the highback 2. For fastening the toes of the boot 3 to the base plate 1
The toe strap provided in FIG.

FIG. 4 is a detailed explanatory view of the toe strap 5, wherein 6a is one band whose one end is fixed to one side wall portion 1a of the base plate 1, and 6b is the other side wall portion 1b of the base plate 1. The other band whose one end is fixed, 7 is a buckle connected to the free end of the one band 6a, 8 is a ratchet belt connected to this buckle 7, and 9 is the ratchet belt 8 passed through the other band 6b. The ratchet claw provided for this purpose is shown.

In such a snowboard binding, when the boot is mounted on the base plate 1, the ratchet belt 8 of the toe strap 5 and the ratchet pawl 9 are disengaged, and the boot 3 is placed on the base plate 1 from above. Ratchet belt 8 as shown in 4
Is inserted into the ratchet claw 9 and the buckle 7 is tightened to fix the toes of the boot 3 to the base plate 1.

[0005]

As described above, the conventional snowboard binding has a channel-shaped cross section, has a large rigidity, and is difficult to be deformed.

However, the bottom plate portion 1d of the binding 1
Is preferably curved in an arc shape around its vertical axis, while it is preferably not curved in the direction of the vertical axis.

The present invention is intended to achieve the above object.

[0008]

SUMMARY OF THE INVENTION A snowboard binding of the present invention includes a base plate having side walls and a bottom plate portion, the bottom plate portion being more elastic than the both side walls and elastic about a longitudinal axis. It is freely bendable and shows rigidity in the direction of the vertical axis.

The heel mounting portion of the bottom plate portion is reinforced.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 1, the heel cup 1c for connecting the rear portions of the side wall portions 1a, 1b of the base plate 1 having a channel-shaped cross section to each other is not provided, and the side wall portions 1a, 1b are made of aluminum or the like. The bottom plate portion 1d of the base plate 1 is made of a rigid material and is made of an elastic plastic material.

Since the snowboard binding of the present invention has the above-mentioned structure, the bottom plate portion 1d of the base plate 1 can be curved around the vertical axis, and therefore has a function of absorbing the impact at the time of sliding, while the both side wall portions are provided. Since 1a and 1b are sufficiently rigid, they are not curved in the direction of the vertical axis and are ideal as a snowboard binding.

The bottom plate portion 1d and the side wall portions 1a, 1
It is also possible to integrally form b with different rigidity and elasticity.

Further, since the portion of the bottom plate 1d of the base plate 1 on which the heel of the foot rests is more susceptible to the load than the other portions, in another embodiment of the present invention, as shown in FIG. 2 on the back side of this portion. An auxiliary plate 10 made of a material such as carbon having elasticity is detachably attached with a screw 11.

The auxiliary plate 10 may be sandwiched between other members.

According to the above embodiment of the present invention, the amount of deformation of the bottom plate portion 1d of the base plate 1 can be arbitrarily changed.

[0017]

As described above, according to the snowboard binding of the present invention, there is a great advantage that the base plate can easily absorb the impact on the boot during the skiing.
