2. Description of the Related Art Unlike a ski using two snowboards, only one snowboard is used. The rider rides one snowboard sideways. That is, the traveling direction of the snowboard is substantially orthogonal to the front-rear direction of the rider. Snowboard boots require rigidity and flexibility. It is required that the snowboard boot and the foot are firmly fixed and that the ankle can be tilted with respect to the sole of the foot. The flexibility of the ankle in the half-pipe, which is a competition event, is also required with respect to the ability to tilt the ankle in the forward and backward directions of the snowboard. That is, it is required that both feet can be freely tilted in the direction in which they face each other. Also, unlike skiing, which is a new sport, unlike skiing, such tilting ability in the left and right direction, especially in the direction in which both ankles approach each other, that is, inward, allows the ankle to tilt in the front-back direction. sex,
In particular, it has been found that it is necessary at the same time as being able to lean forward.

[0003] There is known a structure for giving a snowboard boot the ability to tilt the foot or ankle in the left-right direction. There is known a shoe structure which is tiltable in the left and right direction, in which the upper part (leg) supporting the ankle, which is located above the heel part and above the heel part, is rotatable around a center line facing the front and rear direction of the foot. ing.

[0004] The multiplex structure of the known snowboard boots alone has a resentment of lack of smoothness in tilting the ankle in the left-right direction. Further, with the improvement of exercise techniques, further diversity of exercise is required.

[0005]

The present invention has been made based on such a technical background, and achieves the following objects.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleat position structure for a snowboard boot in which each foot can be easily inclined inward.

Another object of the present invention is to provide a cleat position structure for a snowboard boot that promotes a smooth left-right tilting property without impairing the tilting property of a snowboard boot already given a right-left tilting property. Is to do.

It is still another object of the present invention to provide a cleat position structure for a snowboard boot that diversifies the mobility of the snowboard.

Means for Solving the Problems To solve the above-mentioned problems, the following means are adopted.

The cleat position structure of the snowboard according to the present invention 1 is a cleat position structure of a snowboard boot in which both left and right ankles are required to be inclined inwardly facing each other and the cleat is coupled to the snowboard via an engagement mechanism. Yes, the cleats are deflected inward with respect to the approximate center line dividing left and right for each foot.

A cleat position structure of a snowboard according to a second aspect of the present invention is characterized in that, in the first aspect, the cleat is fixed to a hard resin sole core.

A cleat position structure of a snowboard according to a third aspect of the present invention is characterized in that, in the second aspect, the resin shoe sole core is made of the resin having at least an inner portion hard.

According to a fourth aspect of the present invention, in the cleat position structure of the snowboard according to the first aspect, the cleat is fixed to a hard resin sole core, and the resin sole core supports only an inner portion of each foot. It is characterized by:

According to a fifth aspect of the present invention, in the cleat position structure of the snowboard according to the first aspect, the cleat is fixed to a resin sole core, and the resin sole core is formed of an inner portion and an outer portion with respect to each foot. The inner part is hard and the outer part is soft, and the cleat is fixed to the inner part.

According to a sixth aspect of the present invention, in the cleat position structure for a snowboard according to the fifth aspect, the inner portion and the outer portion are directly connected to each other.

According to a seventh aspect of the present invention, in the snowboard cleat position structure according to the second aspect, the resin shoe sole core is formed of an inner portion and an outer portion for each foot, and the cleat is fixed to the inner portion. The inner part and the outer part are characterized by being capable of being inclined inward and outward.

According to an eighth aspect of the present invention, in the cleat position structure of the snowboard according to the seventh aspect, the inner portion and the outer portion are cut and separated.

[0018]

The anterior-posterior tilting is performed about the ankle axis as the center axis, but the ankle lateral tilting is a rotational motion about the anterior-posterior line near the sole of the foot, that is, the anterior-posterior line lower than the ankle. It is. The front-rear direction line referred to here includes a line inclined by 20 ° to 30 ° with respect to the center line of symmetry of both feet.

In the cleat position structure of the snowboard boot according to the present invention, the inner half of the snowboard boot is firmly fixed to the snowboard via the cleat engaging mechanism. Such a fixed part is at a low position with respect to the surface of the snowboard. The tiltability of the snowboard boot in the left-right direction, which is centered on the front-rear direction line deviated inward from the center line facing the front-rear direction of the foot, is tilting about the center axis set at a high position. Smooth compared to gender.

Since the outer portion of the back of the foot does not press the hard sole, the force for pushing the inclined snowboard boot or the snowboard connected to the snowboard boot back to the original position before the inclination is weak.

The support of the ankle to the snowboard when erecting is sufficient if the support is about half of the inside of the sole.
In snowboarding, it is required to incline the ankle inward. The outward inclination is limited by the stopper. When tilting the ankle inward, it is sufficient to firmly support the inside half of the sole on the snowboard. Such mobility is required for both feet. That is, the cleats of the cleat position structure of the snowboard boot according to the present invention are fixed to the right side for the left foot and to the left side for the right foot. Cleat engagement mechanisms include those of the step-in type, that is, the engagement is automatically performed simply by stepping on the shoe.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) Next, Embodiment 1 of a cleat position structure of a snowboard boot according to the present invention will be described. Generally, a shoe sole has a hard core bottom portion, a hard heel portion, and a hard fingertip portion. Such a hard core material is covered with a soft material inside of a shoe sole and other skin materials. Hardboard soles are used in snowboard boots.

A snowboard boot in which it is required to incline both the left and right ankles inward while facing each other while inclining forward, and to incline the left foot in the forward direction while inclining forward. Cleats fixed to the snowboard engagement mechanism (not shown)
Are connected via

1 and 2 are bottom views showing Embodiment 1 of a cleat position structure of a snowboard boot according to the present invention. The shoe sole core 1 has a smaller area in a plan view than the conventional shoe sole core. The illustrated shoe sole core 1 is for a left foot. The shoe sole core 1 lacks a rigid body that supports about half of the left side (outside) of the back of the foot. The phantom line of the two-dot chain line indicates the left portion (outer portion) of the conventional device.

The shoe sole core 1 is injection-molded using a hard engineering plastic such as nylon. The hard resin is connected to the bottom sole 1 to be bonded to the sole core 1,
It is harder than the material of the upper side shoe soles, the members covering them, and the upper part. The shoe sole core 1 is provided with two cleat mounting holes 2, 2 and 3, which are arranged in the front and rear directions in the front and rear directions, respectively.

An approximate center line in the front-rear direction of the sole surface located on the shoe sole core 1 is indicated by a symbol L. This center line L coincides with the outer boundary of the shoe sole core 1. The cleat 4 is fixed to the shoe sole core 1 by fixing means such as bolts passing through the cleat mounting holes 2 and 3. A front-rear direction line K passing substantially through the center positions of the cleat mounting holes 2 and 2 and the cleat mounting holes 3 and 3 is inside the center line L, that is, the drawing (FIG. 1).
Above is skewed upward. In FIG. 2B, it is shifted to the left.

The cleat 4 is long in the front-rear direction, that is, in the longitudinal direction. The front direction of the cleat 4 is fixed by bolts passing through the cleat mounting holes 2 and 2, and the rear direction of the cleat 4 is fixed by bolts passing through the cleat mounting holes 3 and 3. The sole core 1 supports only the inner portion of the back surface of each foot. A member 5 indicated by a dotted line in FIG. 1 indicates a position of an engagement member fixed to the snowboard.

FIGS. 3 and 4 show a second embodiment of the cleat position structure of the snowboard boot according to the present invention.
The overall shape of the shoe sole core 1 is almost the same as the conventional one.
The shoe sole core 1 is divided right and left at the position of the center line L, and is formed of an inner portion 11 on the right side of the center line L and an outer portion 12 on the left side of the center line L.

The cleat 4 is fixed to the inner part 11. The inner part 11 and the outer part 12 are integrally injection-molded. The left portion 11 is formed by injection molding of a different material from a material softer than the outer portion 12.

FIGS. 5 and 6 show a third embodiment of the cleat position structure of the snowboard boot according to the present invention.
The overall shape of the shoe sole core 1 is almost the same as the conventional one.
The shoe sole core 1 is divided right and left at the position of the center line L, and is formed of an inner portion 11 on the left side of the center line L and an outer portion 12 on the right side of the center line L.

The cleat 4 is fixed to the inner part 11. The inner portion 11 and the outer portion 12 are integrally injection-molded from the same material. This same material is hard. The shoe sole core 1 is divided right and left at the position of the center line L, but is directly connected via a thin portion or a groove 13.

The thin portion 13 includes a center line L. The thin portion 13 forms a kind of hinge portion. The cleat 4 has a rotational property around a center line L passing through the thin portion 13.
It has a gradient. The rotational force can be limited by the thickness of the thin portion and the groove width.

7 and 8 show a fourth embodiment of the cleat position structure of the snowboard boot according to the present invention.
The overall shape of the shoe sole core 1 is almost the same as the conventional one.
The shoe sole core 1 is divided right and left at the position of the center line L, and is formed of an inner portion 11 on the left side of the center line L and an outer portion 12 on the right side of the center line L.

The inner part 11 and the outer part 12 are completely separated or cut. Cleat 4 is the inner part 1
Fixed to 1. The inner part 11 and the outer part 12
It is indirectly connected via another member, for example, an inner portion of the sole (an upper side portion formed of a soft material, not shown). The inner part 11 and the outer part 12 may be made of the same material or different materials. The inner part 11 is formed of a hard material.

The cleat position structure of the snowboard boot described above is formed symmetrically for left and right feet. During exercise,
The left and right feet are inclined to approach each other. The rotation center line of the inclined snowboard boot is located lower than the sole surface. The foot is a front-rear direction line passing through the sole surface or a front-rear direction line at a position slightly higher than the sole surface, and the center line L
The rotation center line K deviated further inward (see FIGS. 1, 3, 5, 7).
(Shown inside).

The rotation of the ankle is not limited to the rotation around the offset center rotation center line K, but includes the rotation around the center line L.
In any case, the lack of a rigid core in the outer portion significantly reduces the force or pressure by which the outer portion of the sole presses the sole.

The rotation center lines K on both sides can be inclined in a direction inward toward the front with respect to the center line L. Such an inclination facilitates the exercise of inclining both ankles in the forwardly inclined posture in a direction facing each other, that is, inward, or in the forwardly inclined posture in the traveling direction.

Regardless of the direction of the rotation center line K, the inward rotation of the ankle around the substantially center line of the cleat biased inward is easy and smooth. Such a rotation / tilt movement is easy for an ankle that leans forward.
