Description

[Detailed description of the invention] (a) Technical field of the invention The invention mainly consists of an outer shell made of a rigid synthetic resin material and a deformable inner boot that can fit the feet and ankles of a skier. The present invention relates to ski boots, and particularly to ski boots that allow the foot to be firmly fixed in the outer shell with good adhesion.

(b) Conventional technology and problems In recent years, the outer shell of ski boots has been molded from lightweight, hard, and impact-resistant synthetic resin materials such as FRP, and inner boots that fit the skier's feet are inserted into the outer shell of the ski boot. Ski boots that secure the feet of people are now appearing.

Although the outer shell made of such a rigid synthetic resin material is excellent for controlling the edge of the ski, it does not conform to the skier's foot, and moreover, it is molded into a shape that fits the size and shape of each individual's foot. Because they have a standardized shape rather than a specific shape, even if you choose ski boots that are sized to match the length of a skier's feet, they will immediately fit the skier's feet and provide a good fit. In most cases, there is a space between the inner boot that wraps around the skier's foot and the outer shell, especially in the upper part of the foot and the area facing the front of the ankle. Spaces tend to form in the areas facing both sides of the heel, making it impossible to maintain close contact and firm retention of the foot against the outer shell, which in turn reduces the operability of the ski.

Therefore, in the past, air was sealed in the space generating part in the outer shell as described above, or a pad that could be filled with air was provided, or a viscous It has been proposed to provide a fitting pad encapsulating a flowable pressure compensating fitting composition.

The above-mentioned method of filling the space inside the outer shell with air pads provides good adhesion to the foot and is comfortable to wear, as well as reducing the space by changing the amount of air filled into the pads. You can fill it up completely, and you can also adjust the pressure of contact with your feet. However, since the filling inside the pad is air, when the pad is pressurized when operating the edge of the ski, the air inside the pad easily flows and compresses, causing the foot to move within the outer shell. , the edge operability of the ski is reduced.

On the other hand, in the above-mentioned fitting pad, the fitting composition in the pad has the property of flowing in response to and adapting to continuous pressurizing force and preventing it from flowing in response to instantaneous pressurizing force. , the foot could be held fixed within the outer shell, making it excellent for maneuvering the edge of the ski, but on the other hand, the size of the space changed due to changes in the thickness of the socks worn on the foot. If you are unable to respond quickly and the space becomes large, you may not be able to completely fill it with the foot extension pads, leaving a space and making it unstable to hold your foot. I get used to it. In addition, when the above-mentioned fitted pads are exposed to cold places, their flexibility decreases and they harden, so when you change the socks on your feet and put on your ski boots again, the cold air will harden them. The fit-tight pads may partially compress the foot, making it uncomfortable to wear, and the fit-tight pads themselves cannot and do not adjust the pressure that holds the foot. However, there was a problem in that it was necessary to prepare a plurality of types of fitting pads of various thicknesses, which was extremely troublesome for skiers.

(c) Purpose of the invention The present invention is a solution to the conventional problems mentioned above.The purpose of this invention is to provide good adhesion to the foot and to enable firm holding, as well as to To provide ski shoes which can surely fill a space in which the skis are worn and which can also adjust the contact pressure of the feet.

(d) Structure of the invention In order to achieve the above object, the ski boots of the invention include an outer shell integrally molded from a rigid synthetic resin material, and a ski shoe that is inserted into the outer shell and is attached to the skier's foot and ankle. In a ski boot having an inner boot that can be adapted to deform, fitting pads are placed on the inside and air pads are placed on the outside at necessary locations between the outer shell and the inner boot.

(e) Example of implementation of the idea Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A cut-in groove 9 reaching up to c is formed, and the lower end connecting portion 3b of the tongue-like member 3 is pivotally connected to the heel portion 2c of the sole so as to close the cut-in groove 9. The ski boot 1 can be tilted through the groove 9 in the direction of the arrow X in FIG. 2, thereby opening the opening of the ski boot 1 and allowing the foot to be inserted or removed from the rear of the ski boot.

The front tab 4 is overlapped with the ankle front part 2d of the outer shell 2 from the inside, and the slot 1 has an edge 4a formed in the ankle front part 2d.
0 and is integrally attached to the outer shell 2 by a plurality of screws 11. Above front tab 4
An air pump 12 is arranged inside the front tab 4, and this air pump 12 is attached to the front tab 4 by a support member 13 and screws 14.
One end of an air supply hose 15 extending downward is connected to the air pump 12 via a valve device 16, and an air pad 8 is connected to the lower end of the hose. Correspondingly, it is arranged in direct contact with the inner wall of the outer shell 2.

As shown in FIG. 8, which is not limited thereto, the valve device 16 includes a pump connection port 16a, a hose connection port 16b, an exhaust port 16c, and an air supply port 1.
A valve casing body 16d having a diameter of 6h, and this valve casing body 16d
An air supply valve 16e provided on the air supply port 16h side of the valve casing 16d, and an exhaust valve 16f provided on the exhaust port 16c side of the valve casing 16d.
and a flow valve 16i provided on the air pad connection side, and a valve stem 16g of the exhaust valve 16f projects outward, and this valve stem 16g is connected to the front tab 4.
By pressing this push button 17, the exhaust valve 16f is opened, and the air pad 8
The air inside can be exhausted. Further, a slit 18 extending vertically is formed in the center of the front part of the front tab 4, and an air pump operating lever 19 is fitted into this slit 18, and a pivot formed at the lower end of the slit 18 is inserted into the slit 18. lever 19 by engaging lever 20
The lever 19 can be rotated about the pivot 20 in the direction of the arrow A in FIGS.
A pump pressing part 21 is provided which also serves to prevent the pump from falling off.
This pressing portion 21 is in contact with the air pump 15.

As shown in FIGS. 1 to 4, the inner boot 5 includes an outer jacket 5a that covers the sole, fingers, instep, ankle, and front part of the ankle, and covers the rear part of the heel of the foot and the rear part of the ankle connected thereto. The outer jacket 5a is inserted into the outer shell 2, and the tongue 5b includes a tongue-shaped part 5b.
is attached to the inner wall of the tongue member 3. Then, as shown in FIG. 4, fitten pads 7 are stacked and arranged corresponding to the instep part of the outer cover 5a of the inner boot 5 and the front part of the ankle connected thereto. The notch 7a formed in the inner boot 5 is engaged with a protrusion 51 protruding from the outer cover 5a of the inner boot 5, whereby the inner boot 5 is held. 5a, the fitting pad 7 and the air pad 8 are stacked in three layers.

Further, 22 is a band that tightens the foot, and 23 is a tightening buckle.

In the ski boots of this embodiment configured as described above, when the skier's feet wearing socks are inserted into the ski boots 1 and fixed, the band 22 and the buckle 23 are separated and the tongue-like member 3 Then, the flexible tongue portion 5b is tilted in the direction of the arrow X in FIG. 2, the opening of the outer shell 2 is expanded, and the foot is inserted into the outer shell 2 from the rear. Thereafter, the band 22 is engaged with the buckle 23 and tightened until the desired and proper pressure is achieved. Next, by operating the lever 19 in the direction of arrow A, air is fed into the air pad 8 and the air pad 8 is inflated.

That is, when the lever 19 is pressed in the direction of the air pump 12, the pressing part 21 of the lever 19 compresses the air pump 12, and the air pressure forces the air into the air pad 8 through the circulation valve 16i and the hose 15. The air pads 8 are inflated one after another. As a result, the space between the outer shell 2 and the inner boot 5 corresponding to the instep part and the front part of the ankle connected thereto is filled, the inner boot 5 is deformed to a shape that fits the foot, and the inner boot 5 and the outer shell 5 are deformed to fit the foot. The fitting pad 7 located between the shell 2 and the air pad 8 is deformed to follow the surface shape of the inner boot 5 fitted to the foot, and the fitting composition in the pad 7 continues to act on the fitting pad 7. The inside of the outer shell 2 is shaped by the inner boot 5, the fitting pad 7 and the air pad 8 to fit the skier's foot. That is, the fitting pad 7 holds the foot in the outer shell 2 in a fixed state, and the air pad 8 completely fills the space created between the fitting pad 7 and the outer shell 2. This ensures good adhesion of the foot and firm retention to the outer shell 2 for good edge operation of the ski, and eliminates the above-mentioned conventional drawbacks.

In addition, the contact pressure against the foot can be adjusted by adjusting the amount of air pumped into the air pad 8 from the air pump 15. Furthermore, when the air pad 8 is tilted forward and skied, the air pad 8 is placed on the front surface of the ankle when skiing with the leg tilted forward. It also has the ability to alleviate excessive pressure on the joint between this and the instep, as well as reduce ankle fatigue. Furthermore, since the air pads 8 are arranged outside the outer shell 2, the fixed holding of the feet will not become unstable.

In addition, in the above embodiment, a case was described in which the fitting pad 7 and the air pad 8 were laminated and arranged on the instep part of the foot and the front part of the ankle connected thereto, but the invention is not limited to this. The placement position can be applied to any area that ensures close contact and firm retention between the shell and the foot.

(F) Effects of the invention As explained above, according to the ski shoes of the invention,
Fitted pads are layered on the inside and air pads are layered on the outside at the necessary locations between the outer shell made of a rigid synthetic resin material and the inner boot that is attached to the shell and transforms into a shape that fits the skier's foot. This method improves the adhesion between the outer shell and the foot, allowing the foot to be firmly held without moving within the outer shell, and ensuring that there is no space between the outer shell and the inner boot, which affects this. can be filled in,
It also has the effect of being able to adjust the contact pressure of the feet.
