Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in ski boots having improved ski operability.

[0002]

2. Description of the Related Art A recent ski shoe is composed of an outer shell formed of a hard and tough resin such as polyurethane, and an inner boot mounted in the outer shell to keep a foot in a close contact state without a gap. ing. And
The outer shell is mainly composed of a shell body that covers the lower part from the ankle and a torso that integrally covers the lower part of the ankle and the lower part of the calf. The torso can be tilted according to the forward leaning posture of the skier. Its lower end is connected to the shell body via a connecting member so as to be tiltable in the front-rear direction. In addition, in order to comfortably hold the foot and improve skiing operability, front entry type ski shoes use tightening devices for each part of the shell body and trunk corresponding to the ankle and instep areas of the inner boots. It is tightened with to create a sense of unity between the foot and ski boots.

By the way, in JP-A-3-195501, when the skier bends the lower leg 1 forward as shown in FIG. 9, the knee actually moves diagonally inward as shown by a straight line a. Regardless, in the conventional ski boot, the connecting member that connects the shell body and the torso portion has the connecting member on the straight line b connecting the two inner and outer ankle bones 5 and 7 of the foot 3 or the longitudinal axis c of the foot 3.
Since it is mounted on a straight line d that is orthogonal to the above, it is assumed that a pressure point is generated inside the lower leg 1 or that the outer edge of the ski is heavy and the ski operation cannot be performed smoothly. As shown, there is disclosed a ski shoe 17 in which connecting members 13 and 15 for connecting the shell body 9 and the trunk portion 11 are mounted on a straight line e that passes through the inner ankle bone 5 and is orthogonal to the straight line a.

Thus, according to such a ski shoe 17, the body portion 11 follows the posture of the skier and tilts in the front-back direction of the shell body 9 with the straight line e as the rotation axis.

However, there are many skiers who have their knees in and their knees escape to the outside when stepping on a plate. However, since it does not have the ability to adjust the knee-insertion direction, the load on the inside edge increases for people who have their knees inward, resulting in a chronic angling condition, resulting in a smooth ski when turning. It was a ski shoe that didn't slide on and was difficult to operate with many catches.

On the other hand, for a person whose knees escape to the outside, that is, a person who goes in and out, the conventional ski boot as described above increases the load on the edge on the out side, so that the edge on the in side of the ski becomes the snow surface. On the other hand, it was not possible to square it sufficiently, and as a result, it was difficult for the ski to slide more than necessary to trace the intended line. As described above, the conventional ski shoes do not have the function of adjusting and correcting the inward or outward movement of the knee caused by the difference in the skeleton of the skier. Therefore, it is difficult for these people to operate the ski. Met.

The present invention has been devised in view of the above circumstances, and provides a ski shoe in which the inward or outward movement of the knee caused by the difference in the skeleton of the skier is corrected to improve the ski operability. The purpose is to

[0008]

In order to achieve such an object, the invention according to claim 1 makes it possible to tilt the body part on both sides of the shell main body in the front-back direction of the shell main body through a connecting member. In the attached ski boot, the attachment position of the body portion by the connecting member can be displaced in the circumferential direction of the shell body, and the rotation axis of the body portion with respect to the shell body can be changed.

The invention according to claim 2 is based on claim 1.
In the ski boot described above, guide grooves, through which the connecting members are inserted, are provided on both sides of the shell body in the circumferential direction, and the connecting members surround the shell body integrally with the body along the guide grooves. The invention according to claim 3 is the ski boot according to claim 1, characterized in that the guide groove through which the connecting member is inserted is provided on each side of the shell body and the trunk. The connecting member, which is provided in the circumferential direction of the main body, is characterized in that it can be displaced in the circumferential direction of the shell main body separately from the body along the guide groove.

(Operation) According to the ski boots of claims 1 and 2, the torso portion tilts in the front-rear direction of the shell body in accordance with the movement of the skier at the time of gliding, but the knee is inward when the plate is stepped on. When a person entering or leaving the boot wears the ski boot, after the connecting member is displaced along the guide groove in the circumferential direction of the shell body integrally with the body, the body may be attached to the shell body by the connecting member. For example, since the axis of rotation of the trunk with respect to the shell body is changed, the direction in which the skier enters the knee is corrected according to the displacement direction.

Further, in the ski boot according to the first and third aspects, when a person whose knees come in or out wears the ski boot, the connecting member is provided along the guide groove of the shell body. If the body is displaced in the circumferential direction and tightened, the axis of rotation of the trunk with respect to the shell body is changed, so the direction in which the skier enters the knee is corrected in accordance with the displacement direction.
