Description

[Detailed description of the invention] ski shoes for cross country The present invention relates to a cross-country ski shoe according to the generic part of claim 1. .

This type of ski shoe for Los Country is covered by West German Patent No. 2942806. It has been described. In this known cross-country ski shoe, the supporting surface is It is located at the front edge of the bottom. Furthermore, the hanging member bent from the wire rod is cross-country. They are anchored (buried) directly in the soles of ski boots. Such a configuration is commercially available. This has been realized in products that are made of high-quality materials, but this is because the material of the sole has sufficient hardness. This is only possible if However, the free-time skier's cross cant Soft (elastic) soles are excluded in ski boots for ski use. like this The soft sole has the tear-resistant strength necessary for directly anchoring the hanging member. not present.

Therefore, according to German Patent Application No. 33 34 144, the hook part The material is fixed to a metal plate-shaped insert, which is also anchored (embedded) in the sole of the shoe. It has already been proposed to do so. However, in this case, the metal insert The disadvantage is that the material is foreign to the plastic sole. By this This will prevent gaps and cracks from forming at the edges of the insert as the foot rolls. stress is generated. In addition, in this case a support surface that cooperates with the ski padding Since the sole consists of a soft sole material, premature wear of the support surface occurs.

Just to be sure, there are some products on the market that are related to ski binding. The mating part itself is made of hard plastic and is embedded in the sole of the shoe.

However, this does not have a latching member bent from wire, so it is different from another type. They are ski shoes.

The object of the present invention is to eliminate the drawbacks of known cross-country ski boots and to provide a shoe with a suitable sole. Although it is flexible, the latching member is securely anchored to the sole of the shoe, and the latching member securely anchors the foot. To provide ski shoes for cross-country skiing that do not hinder the movement of people.

Furthermore, the sole section holding the latching member is permanently connected to other sole sections. I want to.

This problem is solved according to the invention by the features of claim 1. Places like this By applying this function, the hanging member made of a wire rod that has been bent several times becomes flexible on the sole of the shoe. It is now possible to securely anchor inside the soft elastic sole of the shoe without damaging it. .

According to the embodiment of claim 2, the part of the sole that cooperates with the ski binding has a long service life. You can get a term.

According to the arrangement according to claim 3 and/or 4, the effective The contact surface becomes larger.

According to the structure described in claim 5, the resistance to the shifting movement of the ski boots is reduced. can be done.

The arrangement according to claim 6 is characterized by premature wear around the sole. With the configuration described in claim 7, the stability of the sole can be selectively increased in the lateral direction. Ru. In this case, the longitudinal elasticity necessary for transfer is maintained.
