Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to ski boots molded from a flexible and rigid material (such as plastic), in which the ski boots can be put on and taken off from the rear of the shoe. It is something.

(Prior Art) In recent years, ski shoes made of flexible and rigid plastic have become popular.

However, because plastic ski boots have a high rigidity, even if they are tightened with a buckle, there is a slight gap at the seam, making it difficult to secure the foot to the shoe. .

Recently, this drawback has been improved and the front instep and sole of the ski boot are integrally formed into a shoe shell.
Ski boots have also been provided in which the legs are formed separately to form a rear cuff, and the rear cuff is secured to the rear part of the shoe shell by any means such as rivets or screws.
These ski boots open the rear cuff to the rear and allow the foot to be inserted and removed from the back of the shoe.
No. 52-118360.

Such ski boots had the disadvantage that the opening angle of the rear cuff to the rear was only about 35 degrees, making it difficult to insert and remove feet wearing thick socks smoothly.

Furthermore, the forward inclination angle of the rear cuff changes due to the thin and thick shins of the skier's feet, which may interfere with the desired forward leaning posture that is important for skiing.

(Means for Solving the Problems) The present invention has been improved in view of the above drawbacks, and is a ski shoe consisting of a shell body 1 in which the front instep and the sole are integrally formed, and front and rear cuffs 2 and 3. The cuff parts are formed into a front cuff 2 that supports the front part of the foot and a rear cuff 3 that supports the rear part of the foot.
3 are interlocked to expand the opening angle to make it easier to put on and take off shoes, and the foot is held between the front and rear cuffs 2 and 3, which is influenced by the narrow and thick shins of skiers' feet. To provide ski shoes that allow a desired forward leaning posture to be maintained.

(Embodiment) An embodiment of the ski shoe of the present invention will be described with reference to the drawings.

That is, the ski boot of the present invention is made of flexible and rigid plastic, and consists of a shell body 1 that integrally forms the front instep and the sole, a front cuff 2 that supports the front part of the foot, Rear cuff 3 that supports the rear part of the foot
There is a through hole 15 near the center of the lower part of the shell 1.
The through hole 15 is provided near the front of the lower part of the front cuff 2.
A through hole 25 is provided in a portion corresponding to the rivet 5, and the rivet 5 is inserted into the through hole 15, 25 and rotatably attached.
In addition, a through hole 26 is provided at the lower rear side of the front cuff 2,
A long-diameter through-hole 36 is provided in a portion corresponding to the through-hole 26 at the lower front of the rear cuff 3, and the rivet 6 is inserted into the through-holes 26, 36 and rotated, and the long-diameter through-hole 3
A cable hook 10 and a shaft 8 are formed in the rear part of the shell 1, and a through hole 18 is formed in the shaft 8.
is provided to form a shaft 7 on the rear inner side of the rear cuff 3,
The shaft 7 has a cable hole 27 and a through hole 17, and the shaft 8 has a through hole 4' provided at the lower end of the connecting rod 4 and a through hole 1 of the shaft 8.
8 are rotatably connected to each other with a rivet 8', and the shaft 7 is rotatably connected to the through hole 4'' provided at the upper end of the connecting rod 4 and the through hole 17 of the shaft 7 with a rivet 7'. connect,
An instep presser 11 is disposed inside the instep of the shell 1, one end of the cable 9 is fixed to the instep presser 11, and the other end of the cable 9 is connected to the cable hook 10 through the cable hole 27 of the shaft 7. These ski boots are characterized in that they are fixed to the rear cuff 3 by any means. The cable 9 may be fastened to the rear cuff 3 by direct fastening or by using a known buckle.

(Function and Effect) The method of using the ski boots of the present invention having the above-mentioned configuration is to insert an inner shoe (not shown) into the shell 1, and then from the state where the front and rear cuffs 2 and 3 are closed as shown in FIG. When the rear cuff 3 is opened rearward with one's hand, the connecting rod 4 pivoted on the shaft 7 rotates clockwise about the shaft 8, and the rear cuff 3 is opened. Rear cuff 3
As it opens rearward, the long diameter through hole 36 and the through hole 2
The rivet 6 pivoted on the shell body 1 moves in the long-diameter through hole 36 to push the front cuff 2 upward, rotates counterclockwise around the rivet 5 pivoted on the shell 1 as a fulcrum, and the front cuff 2 open forward. In other words, rear cuff 3
By opening the front cuff 2 rearward, the front cuff 2 also opens forward. The instep presser 11 is located between the shell 1 and the inner shoe by releasing the tension on the cable 9, and is in close contact with the inside of the instep of the shell 1, so there is no problem in inserting the foot. The opening of the front and rear cuffs 2 and 3 is such that the front cuff 2 opens approximately 13 degrees forward and the rear cuff 3 opens approximately 45 degrees rearward, so the front and rear cuffs open approximately 58 degrees. Compared to the cuff of the ski boot No. 118360, which has a cuff opening of approximately 35 degrees, the cuff opens wide in the front and back, making it easier to insert and remove the foot, and at the same time, it is also convenient to put on and take off the ski boot.

Next, the skier grabs the front and rear cuffs 2,
When the cuffs 3 are closed inwardly, the skier's feet are clamped in the reverse order of operation of the front and rear cuffs 2 and 3 when they are opened. In this case, the instep presser 11 presses the instep of the skier toward the heel of the skier through the inner shoe by the tension of the cable 9, thereby stabilizing the foot. The configuration for tensioning the cable 9 is as follows.

The cable 9 has one end fixed to the instep presser 11,
The other end is the cable hook 10, and the cable hole 2 of the shaft 7
7 and is fixed to the rear cuff 3 by any means, so when the front and rear cuffs 2 and 3 are fully opened from the state shown in FIGS. 2 and 5 and raised as shown in FIG. The shaft 8 and the cable hook 10 become almost in a straight line, and the cable 9 reaches the maximum tension state parallel to this, and when pushed further, it passes the dead center and the shaft 8 shifts to the outside as shown in Fig. 3. The shaft 7 is located inside the shaft 8, and the cable hook 10 is used as a fulcrum and the cable 9 is tensioned so that the rear cuff 3 always holds the rear of the skier's foot and at the same time tensions the instep presser 11.
The front cuff 2, which is linked to the rear cuff 3, is pulled together to hold the front part of the foot, ensuring that the ski boots are worn securely.

As explained above, in the ski boots of the present invention, when putting on and taking off the shoes, the front and rear cuffs 2 and 3 open wide in the front and back direction, making it easy to insert and remove the feet, and the skier's feet are held between the front and rear cuffs. Because of this, it is easier to adapt to the thin and thick shin area, maintain the desired forward leaning posture, and furthermore, the instep part can be stably pressed in the direction of the heel by the instep presser 11, making skis easier to ski. Shoes are useful.
