Description

[Detailed Description of the Invention] A. Field of Industrial Application This invention relates primarily to ski boots used for alpine skiing, and in particular to improvements in shoes whose tops can be elastically tilted slightly forward.

B. Prior Art and Problems If the top of alpine skiing shoes is relatively hard and elastic and can be tilted to some extent, the shoes can ski stably, quickly, and with less fatigue.

Shoes with elastically tiltable tops have been developed (Japanese Patent Application Laid-open No. 49102/1983).

As shown in FIG. 3, in this ski shoe, the lower part of the front cuff 1 forming the top part is pivotally connected to the shell 2 via a joint shaft 3.
An elastic piece 4 is provided along the surface of the elastic piece 4.
The tip portion of the shell 2 is fixed to the shell 2 via a fixed shaft 5.

Ski shoes with this structure have a front cuff 1 and a rear cuff 6.
When the top part 7 formed of
It has a function to control the tilting of the

C. Conventional Problems However, in ski shoes with this structure, the top part 7 does not tilt when pressed with the hand, and the top part 7 does not tilt when a fairly strong force is applied with the foot. Because of this design, when the top part 7 tilts, a significantly strong local load acts on the fixed shaft 5, and it is necessary to fix the fixed shaft 5 particularly firmly to the shell 2, and this part must be firmly fixed. There was a drawback that this part was easily damaged.

In addition, since four locations (two locations on both sides of the front cuff) are attached to the shell 2, there is also the drawback that manufacturing is time consuming.

The ski shoes of this invention were developed with the aim of eliminating these drawbacks, and an important purpose of this invention is to allow the elastic piece of the front cuff to wrap around the shell without sticking to its end. and the rear cuff, and the side of the elastic piece is placed on the piece provided on the shell to restrict its movement, so there is no need to fix the end of the elastic piece to the shell. It is possible to prevent local damage to the connecting part between the elastic piece and the shell, and the contact surface between the elastic piece and the contact piece can be widened in terms of structure, and the collision force per area can be reduced. To provide a ski shoe which can prevent failure and damage of a member for braking the movement of the ski shoe, and which can be easily manufactured since there is no need to fix the end of the elastic piece to the shell.

D. Means for Solving the Problems of the Conventional Ski boots have a top portion that is connected to the shell so that it can tilt forward by a predetermined angle.

The top part consists of a front cuff that covers the front, and a rear cuff that covers the rear part. It is pivoted on the outside of both sides of the shell so that it can tilt forward and backward.

The front cuff has an elastic piece extending along the outer surface of the shell in a direction away from the joint axis.

Furthermore, a contact piece is provided on the surface of the shell, with which the side surface of the elastic piece comes into contact, and the contact piece follows the movement trajectory so that the side surface of the elastic piece comes into contact with the front shell when it rotates in a direction that tilts forward. It is arranged.

Furthermore, the rear cuff is located outside of the elastic piece of the front cuff, and the elastic piece of the rear cuff is sandwiched between the shell and the elastic piece of the front cuff, which is sandwiched between the shell and the rear cuff, and the elastic piece of the front cuff is sandwiched between the shell and the shell. The side of the body touches the body, restricting movement.
The front cuff and the back cuff are elastically tilted by the elasticity of the elastic piece.

E. Function The function of a preferred embodiment of this invention will be explained based on FIG. 1.

The front cuff 1 and the rear cuff 6, both sides of which are attached to the shell 2 via the joint shaft 3, can be tilted relative to the shell 2. When the front cuff 1 tilts, the elastic piece 4 provided thereon rotates to the left in FIG. 1, and the rear end of the elastic piece 4 moves upward. Since a contact piece 8 is provided protruding from the surface of the shell 2 at a position where the upper surface of the elastic piece 4 contacts, the upper surface of the elastic piece 4 contacts this contact piece 8, and the tilting movement of the front cuff 1 is restricted. Ru.
That is, since the rotation of the elastic piece 4 is limited by the contact piece 8 of the shell 2, the front cuff 1 tilts by the amount that the elastic piece 4 itself elastically deforms.

The elastic piece 4 of the front cuff 1 is sandwiched between the shell 2 and the rear cuff 6 so that the upper surface of the elastic piece 4 comes into contact with the contact piece 8 of the shell 2 and does not shift from the position.

That is, the elastic piece 4 that limits the forward inclination of the front cuff 1 is
The side surface touches the abutment piece 8 of the shell 2, and the movement of the elastic piece 4 is restricted within the interior surrounded by the shell 2, the rear cuff 6, and the abutment piece 8. For this reason, the elastic piece 4
Compared to conventional ski boots in which the end of the elastic piece 4 is connected to the shell 2 with a fixed shaft 5, the surface where the end of the elastic piece 4 contacts the shell 2 can be made longer, and excessive local loads acting on the shell 2 can be limited. , elastic piece 4 and shell 2
It is possible to realize the feature of reliably maintaining elastic support for a long period of time.

In addition, there is no need to connect the end of the elastic piece 4 provided on the front cuff 1 to the shell 2, and both the front cuff 1 and the rear cuff 6 can be connected to the shell 2 using the joint shaft 3, making manufacturing easy. It is also possible to realize the features that can be achieved.

F Preferred Embodiments Hereinafter, embodiments of this invention will be described based on the drawings.

The alpine ski shoe shown in FIG. 1 consists of a shell 2 molded to the outer shape of the foot and a top part 7 mounted above the shell 2.

The top portion 7 consists of a front cuff 1 that covers the front of the foot and a rear cuff 6 that covers the rear. Ru.

The front cuff 1, the rear cuff 6, and the shell 2 are made of synthetic resin such as polyurethane or vinyl chloride.

Further, although not shown, inner soles are placed inside the front cuff 1, rear cuff 6, and shell 2, and shoes are put on by inserting the feet into the inner soles.

The front cuff 1 and the rear cuff 6 are tiltable in the front-rear direction via the joint axis 3 so that when the footwear is tilted forward with respect to the shell 2, they both tilt forward as one. It is pivoted to Ciel 2.

The joint shaft 3 passes through the rear cuff 6, the front cuff 1, and the shell 2, and has wide brim-like ends at both ends to connect the three.

Top part 7 formed by front cuff 1 and rear cuff 6
The tilting movement of the front cuff 1 is controlled via the elastic piece 4 of the front cuff 1 so that it does not tilt freely but elastically.

Therefore, as shown in FIG. 1, the front cuff 1 has an elastic piece 4 extending along the outer surface of the shell 2 in a direction away from the joint axis 3.

Although FIG. 1 shows the left side of the shoe, the front cuff 1 is preferably provided with elastic pieces 4 symmetrically on both left and right sides. Although the elastic pieces 4 on both sides of the front cuff 1 are not shown,
It is also possible to connect them to each other around the rear of the shell.

The movement of the elastic piece 4 of the front cuff 1 is restricted by the abutment piece 8 of the shell without having its end fixed to the shell with a shaft as in the conventional case. That is, when the top part 7 is tilted forward, when the top part 7 rotates to the left in FIG. The contact piece 8 is positioned above the elastic piece 4 in its movement locus, as shown in FIG.

Preferably, the contact piece 8 is formed to be long so as to protrude from the surface of the shell 2, and to extend along the upper surface of the elastic piece 4, as shown in FIG.

Further, it is preferable to provide a contact piece 8 on the lower side of the elastic piece 4 to elastically restrict the rearward tilting of the top portion 7.

The elasticity of the top portion 7, that is, the degree to which the top portion 7 tilts forward when a certain tilting force is applied to it, is determined by:
The width, thickness, and length of the elastic piece 4 can be adjusted. The longer, thinner, and thinner the elastic piece 4 is, the more flexibly the top part 7 will tilt; conversely, the shorter, wider, and thicker the elastic piece 4, the harder the top part 7 will tilt.

The elastic piece 4 of the front cuff 1 is, as shown in FIG.
It is sandwiched between the rear cuff 6 and the shell 2, which are located outside of this. Therefore, the rear cuff 6 is located outside the front cuff 1, and at least the portion of the rear cuff that covers the elastic piece 4 is located outside the front cuff 1. Therefore, the joint axis 3 is
3 with front cuff 1 sandwiched between rear cuff 6 and shell 2
Connect people.

This invention does not limit the extension direction of the elastic piece 4 to the lower rear part of the joint shaft 3 as shown in FIG. 1. For example, although not shown, it may extend directly below the joint shaft 3. It is possible.
