Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot fixing device, especially for ski boots.

[0002]

BACKGROUND OF THE INVENTION Several devices are presently known for fixing the instep or heel or metatarsal region of the foot to the inside of a shoe.

Some of these interact with the projecting flaps of the instep at the ends of the screw plugs that are rotatably incorporated in the rear part of the shoe, for example in the rear part of the rear hips, and that belong to the knob and are arranged in the hips. There is known a device including a knob having a pressing tool.

However, it is said that this known type of device, when actuated by the knob, actually produces a pressure on the flap which is concentrated on a very small area consisting of the area occupied by the pusher. Have a problem.

This configuration makes it difficult to adapt the fixation device to various anatomical shapes of the heel and foot,
Further pain is caused by the concentration of pressure on a small area that is not optimal for all skiers.

It is known to use a cable which partially surrounds the flap projecting from the upper boot or the inner boot located inside the shoe, but it still does not solve the above problem.

As a partial solution to these problems,
The present applicant applied for Japanese Patent Application No. 63-231416 on September 14, 1988, which was interposed in the heel region between the rear inner surface of the rear waist leather and the foot of the skier. A new type of heel fixation device is disclosed which consists of at least one wedge-shaped element.

Means are provided for adjusting the position of the wedge-shaped element.

While this arrangement is undoubtedly effective, it is not possible with this device to adjust the degree of inclination of the flaps, but it is locally applied by the use of rigid fastening elements. It has the problem that pressure areas are formed.

As another conventional example, French Patent Application No. 1,406,610 is known. It features one or more elements that are inflated by a gas, a fluid, or a mixture of the two, interposed between the inner portion of the footwear and the foot to adjust the fixation of the footwear to the foot. Claims a device for doing so.

The main problem with this French application is that it requires suitable external means, such as a pump or a pressurizing cylinder, to be able to inject the fluid.

This inflating operation is tedious, and more severely, there is a problem that the pump means for restricting use must be accommodated in a person's pocket, hand, bag or the like.

French patent 74.39713 is further known as a partial solution to this problem,
It discloses means for pumping air into a pad provided between the lumbar skin and the inner lining.

However, this pumping means has the problem that it has dimensions that are almost non-negligible so as to substantially change the overall aesthetic appearance of the shoe.

Furthermore, the user must have some manual operating skill to create the required degree of pressure in the pad, and the pumping means further requires proper operation thereof. Water can enter the interior, which can be dangerous, and can cause problems during operation.

Further, as another conventional technique,
No. 321,817 and April 3, 1973
The German patent filed on the 0th is known. that is,
Disclosed is a device formed by a bellows member pivotally supported at the sole of a shoe. The actuation of the element causes air to be pumped into a matching pad located inside the shoe.

However, in this solution, the bellows member wears rapidly due to contact with the ground, which leads to failure. Furthermore, the required bottom holding means, which are provided because the sole of the shoe is in constant contact with the snow, make it difficult to actuate during the contraction process, which is a great difficulty in using the bellows member. I have a big problem that I encountered.

Furthermore, French Patent No. 65.03257 is further known as another prior art. It discloses a device including a knob for compressing a liquid suitable for sequentially compressing the air dispensed in a bag located inside the shoe.

However, even this solution has the following problems due to its considerable complexity in actual use. That is, it entails the use of an external actuator, such as a knob that reliably increases in size, and the need to use two different containers for liquids and air, and also for connecting the containers. There is also a problem that the connection diaphragm may be damaged.

Finally, Italian Patent Application No. 59393B / 88, filed October 28, 1988, discloses a liquid pumping device applied to ski boots for fixing the heel. It provides form-fitting compression provided between the posterior medial and lateral portions of the instep proximate to the heel 2
It is constituted by an adjustable piston pump for liquids with a lever connected to two elastic wrapping bags.

However, even in this case, there is a problem that the size is considerably complicated in practice and the size of the shoe is substantially changed.

[0022]
