BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ski shoes with improved walking performance.

0002

[Prior Art] Modern ski boots consist of an outer shell molded from a rigid plastic material such as polyurethane, and an inner boot that is attached to the outer shell to keep the feet in close contact with each other without any gaps. There is. In order to hold the foot comfortably and to improve the operability of the ski, each part of the outer shell that corresponds to the ankle and instep area of the inner boot is tightened with a buckle or other tightening device, so that the foot and the ski are tightened. I feel a sense of unity with the shoes.

[0003] However, although tightening the tightening device in this manner improves the operability of the ski, the reality is that the ease of walking during breaks and the like is impaired. Therefore,
Recently, ski boots such as those disclosed in Japanese Patent Publication No. 61-9042, for example, have been proposed in order to make it easier to walk while wearing ski boots. As shown in FIG. 5, a space 5 is provided at the rear of the body 3 pivoted to the shell body 1, and a swing piece 9 is rotatably inserted into the space 5 via a swing pin 7. The rocking piece 9 is supported by a torsion spring 11.
The lower part of the oscillating piece 9 is pressed so as to be in constant contact with the stopper piece 13 having an L-shaped cross section fixed to the shell body 1.
By pressing the upper part of the shell body 1 against the protruding edge 15 formed at the upper edge of the cavity 5, the body 3 is tilted forward.
It was designed so that it would be locked.

As shown in FIG. 6, when the upper part of the swinging piece 9 is pressed in the direction of the arrow against the spring force of the torsion spring 11 during a break or the like, the locked state of the body part 3 is released and the body part 3 is released. Part 3
When the skier is released from the shell body 1 and the skier bends forward, the forward tilted locked state of the torso 3 is automatically restored.

[0005]

[Problem to be Solved by the Invention] However, in the above ski boots, even if the torso is released from the shell body, when the skier bends forward while walking, the torso automatically returns to its original state. It was locked, and it was impossible to maintain a comfortable walking condition with the torso released. The present invention has been devised in view of the above circumstances, and provides ski boots that can reliably maintain the released state when the torso is released from the shell body, thereby improving walking performance. The purpose is to

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an outer shell consisting of a shell body and a trunk, an inner boot installed in the outer shell, and an inner boot that is attached to the trunk and the shell main body. In a ski boot equipped with a tightening device for opening and closing the upper part, a locking part is formed at the rear part of the shell body, and a base part of the support member is rotatably supported at the rear part of the torso part, and A locking member biased by a spring in the direction of engaging with the locking portion is movably supported at the tip of the support member, and when the locking member is engaged with and disengaged from the locking portion, the locking member is attached to the shell body. On the other hand, the body can be switched between a fixed state and a fixed release state.

[0007]

[Operation] According to the present invention, if the locking member is moved against the spring force to release the locking state with the locking portion during a break, etc., the trunk portion is released from the shell body. This allows the torso to freely tilt forward and backward as the skier walks, and the torso does not interfere with the skier's walking. When skiing, if the locking member is locked to the locking part, the torso is fixed to the shell body, so the skier's weight shift is transmitted from the shell body to the ski through the torso, allowing the skier to operate the ski. can be done with certainty.
