Footwear crampon

Abstract

A crampon including a body extending lengthwise from a rear end to a front end, widthwise between a first side and a second side, and heightwise between a supporting surface and a receiving surface, the crampon including points projecting in the area of the supporting face, as well as a structure for retaining a boot in the area of the receiving surface. The crampon includes a device for adjusting the longitudinal bending strength of the body.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based upon French Patent Application No. 12 / 01443, filed May 22, 2012, the disclosure of which is hereby incorporated by reference thereto in its entirety, and the priority of which is claimed under 35 U.S.C. §119.BACKGROUND[0002]1. Field of the Invention[0003]The invention relates to a crampon adapted to be affixed to an article of footwear, such as a boot. Such crampon may be used in disciplines such as mountaineering, walking or climbing on snow or ice, climbing frozen waterfalls, or the like.[0004]2. Background Information[0005]Conventionally, a crampon comprises a body extending lengthwise from a rear end to a front end, widthwise between a first side and a second side, and heightwise between a supporting surface and a receiving surface. In fact, the body is dimensioned so that the receiving surface receives the sole of the boot. The crampon includes points projecting in the area of the supporting surface, in order...

AI Technical Summary

Benefits of technology

The invention is a crampon that can be attached to a boot for use on various terrains. It improves the functionality of crampons by making them suitable for all situations and styles of practice. The crampon allows for flexibility in its response to forces applied to different points on the ground, which results in better support and reduced user fatigue. Overall, the crampon is more versatile and effective in cooperating with the ground compared to previous versions.

Problems solved by technology

As a corollary, however, a disadvantage of a flexible crampon is user fatigue in highly inclined or vertical passages, such as may be encountered on a glacier or an ice wall.

Indeed, the flexibility of the crampon requires the user to apply significant forces to control and maintain support on steep slopes or in the walls, as, in this case, the grip on the ground occurs mainly through the front points, which requires a substantial strain on the calves.

In addition to fatigue in highly inclined or vertical passages, the accuracy of the front support, although correct, is not optimal.

As a corollary, however, a disadvantage of a rigid crampon is user fatigue in horizontal or slightly inclined passages, such as found on glaciers or on domes.
