Description

[Detailed description of the invention] This invention uses reinforced plastic glass fiber (Fiberglass assRei) which is impregnated into the exterior and interior and has an integral structure.
This invention relates to mountain climbing shoes that have improved waterproofness with a layer of resin (nforced plastics).

Conventionally, the exterior and interior of the torso of mountain climbing shoes are made of leather or fabric so that they can be bent freely, and felt, leather, cloth, etc. is inserted as a core material between the exterior and interior. ing.

However, although these leathers and fabrics have the advantage of being able to bend freely at the ankle, they are also susceptible to water infiltration, so water may seep into the shoes especially when used in snowy areas, or they may freeze during the cold season. There was a problem that it hardened.

On the other hand, climbing shoes made of plastic are available, but although they can prevent water from entering, they are entirely made of plastic, so they do not conform to the foot and cannot be bent at the ankle. When walking on a slope, the ankles cannot be bent and the legs must be bent unnaturally, making walking difficult and even dangerous.

The present invention has been made with attention to the above-mentioned points, and has a sole-shaped bottom part, and covers from the side part to the top part as it goes from the side part on the division side to the toe part. A reinforced plastic fiber layer shaped to be open leaving at least the toe end, except for the bottom part, is interposed between the exterior and interior by impregnating it with a resin made of the same material as the fiber layer and integrating it. To provide mountain climbing shoes which are designed to have waterproof properties inside the shoes, are suitable for use in snowy areas such as climbing snowy mountains, can be bent freely at the ankles, and are easy to get used to the feet, making it easy to walk. The purpose is to

Another purpose of the present invention is that by interposing a reinforced plastic glass fiber layer from the side surface near the section or toe section to the bottom surface, the physical strength of this area is increased and it can be tightened strongly with a crampon band, etc. Our goal is to provide mountain climbing shoes that won't hurt your feet even when you're climbing.

Furthermore, another object of the present invention is that, as a chemical property of the reinforced plastic glass fiber layer, even if the reinforced plastic glass fiber layer and the exterior or interior are separated, a resin can be applied to the reinforced plastic glass fiber layer and both sides can be welded. To provide mountain climbing shoes in which peeling can be easily repaired to its original state by doing so.

Next, an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a mountain climbing shoe, the torso 2 of which is defined by an outer cover 3 and an inner cover 4 made of leather, for example, and a side part on the side of the section or near the toe area, and from the top to the bottom. A reinforced plastic glass fiber layer 5 is interposed between the outer cover 3 and the inner cover 4.

The outer cover 3 and inner cover 4 are impregnated with a resin, such as an epoxy resin, made of the same material as the reinforced plastic glass fiber layer 5, so that these three layers form an integral structure.

As shown in FIG. 3, the reinforced plastic glass fiber layer 5 is shaped into a bottomed part with the top surface open leaving at least the tip of the toe, the upper end of the rear side is located below the section, and the upper end of the front side is located below the section. is curved and extended inward to cover the instep and toes of the foot.

Further, a convex flange 6 is formed around the bottom side surface of the reinforced plastic glass fiber layer 5.

The lower end of the jacket 3 extends and is joined to the upper surface of the collar 6.

A cork material 7 as a cushioning material is disposed on the bottom upper surface of the reinforced plastic glass fiber layer 5, and the resin of the reinforced plastic glass fiber layer 5 impregnates the pores of this cork material 7 to form an integral structure. ing.

For example, an epoxy resin layer 8 is coated on the portion extending from the bottom of the jacket 3 and the end surface of the flange portion 6.

A sole 9 made of rubber or the like is attached to the bottom surface of the reinforced plastic glass fiber layer 5, which is interposed between the outer cover 3 and the inner cover 4 and has an integral structure with the torso 2, using an adhesive such as bond. has been done.

A felt 10 is disposed on the upper surface of the cork material 7, and the cork material 7 and the felt 10 form the inner sole of the shoe.

Incidentally, the reference numeral 11 in the figure is a felt provided on the inner surface of the inner jacket 4.

In such a structure, the reinforced plastic glass fiber layer 5 is interposed between the outer cover 3 and inner cover 4 on the side of the sock, which allows water to easily enter and is easily damaged if tightened with crampons or the like. It prevents water from entering, making it suitable for use in snowy areas.It also increases physical strength, so it protects the entire foot without hurting the foot, and it also makes the shoe tougher.

In addition, the reinforced plastic glass fiber layer 5 is not interposed in the ankle part that needs to be bent, and the shape is formed by the flexible outer cover 3 and inner cover 4, so the ankle part can be bent freely. It conforms well to the foot and is especially easy to walk on slopes.

Furthermore, if the exploding cover 3 or inner cover 4 and the reinforced plastic glass fiber layer 5 peel off, the peeling can be easily repaired to its original state by applying a resin to the reinforced plastic glass fiber layer 5 and welding both sides.

Incidentally, the resin of the reinforced plastic glass fiber layer 5 enters and is impregnated into the gap between the cork material 7 serving as a cushioning material, thereby reinforcing the brittleness of the cork.

In this invention, the outer cover 3 and the inner cover 4 may be made of any fabric other than leather, as long as it easily conforms to the foot and is impregnated with the resin of the reinforced plastic glass fiber layer 5.

Similarly, the cork material 7 may be of any type as long as it has properties as a buffer material.

Further, the resin forming the reinforced plastic glass fiber layer 5 is not limited to epoxy resin, but may be any thermoplastic resin having the same chemical properties.

Furthermore, the epoxy resin layer 8 is shaped to prevent wear of the outer cover 3 and the flange 6, and also to prevent peeling of each part, but if the lower part is shaped or coated up to the upper surface of the rubber sole 9, It is possible to prevent peeling of each part.

As mentioned above, the climbing shoes of the present invention have a reinforced plastic glass fiber layer interposed between the outer side of the sock and the inner layer, which prevents water from entering from the side of the shoe, where water easily enters. It is suitable for use in snowy areas such as snowy mountains, and does not hurt the feet even when tightened with crampons, etc., and protects the entire foot.

In addition, the ankle part, which needs to be bent, is not covered with a reinforced plastic glass fiber layer, making it easy to fit around the foot.
Since it is internal, it can be bent freely at the ankle, making it easy to walk on slopes such as when climbing mountains.

Furthermore, the chemical properties of this reinforced plastic glass fiber layer mean that even if the reinforced plastic glass fiber layer and the exterior and interior peel off, by applying resin to the reinforced plastic glass fiber layer, both layers will be reattached and restored to their original state. It also has the effect of being easy to repair.
