Abstract
A crampon removably attached to a shoe having a plurality of teeth oriented in an angled, noncolinear fashion, such as on the faces of a polygon, on both a heel and toe portion of the crampon. The toe portion of the crampon further includes a plurality of slots which receive a plurality of pick elements selected from a variety of interchangeable pick elements. The variety of pick elements includes a double flat pick, a single reverse angle pick, a flanker pick, a tooth claw pick and a novel tubular pick. The crampon according to the present invention provides enhanced traction by inhibiting a skating action resulting from the substantially linearly disposed teeth of prior crampon designs, while providing a maximum flexibility by interchangeably receiving a variety of pick elements.
Claims20
A crampon removably affixed to a shoe for providing enhanced traction, comprising:
- a sole section and a heel section, wherein each section comprises a plurality of teeth dimensioned by a thickness and a width greater than said thickness;
- substantially rigid means for retaining said sole section and said heel section in relation to the sole and the heel of said shoe, respectively in a generally outward manner therefrom, said plurality of teeth being further disposed to provide a substantially noncolinear arrangement of said teeth;
- and
- means for removably affixing said substantially rigid means for retaining to said shoe.
A crampon comprising:
- a toe portion having a continuous peripheral portion comprising the majority of a polygon having at least one tooth on the surfaces forming the majority of a polygon;
- a heel portion having a continuous peripheral portion comprising a plurality of surfaces including at least one tooth thereon, wherein said surfaces form a majority of a polygon;
- means for connecting said toe portion and said heel portion;
- and means for removably securing said toe and said heel portion to a shoe.
A crampon, comprising:
- a formed member having a plurality of nonparallel, nonorthogonal adjacent portions forming a majority of a polygon;
- a plurality of teeth, wherein at least one tooth is associated with the portions of said formed member forming said majority of a polygon;
- and
- means for securing said formed member to a shoe.
A crampon, comprising:
- a formed member comprising:
- a plurality of surfaces;
- at least one substantially planar tooth associated with each of a plurality of said surfaces, wherein
- the majority of teeth are obliquely disposed relative to adjacent teeth.
A crampon comprising:
- a plurality of picks;
- and
- a formed member having a plurality of teeth extending substantially perpendicular from the plane of said formed member, further including means for removably securing said plurality of picks therein extending transversely through said plurality of picks in the plane of said formed member and being removable at the periphery of said formed member.
A tubular pick comprising:
- a substantially flat rear portion for securing to a crampon;
- and
- a tubular front portion to engage the climbing surface, having an aperture extending axially along the tubular surface of said tubular front portion;
- and
- a transitional portion interposed between said tubular front portion and said rear portion wherein said aperture is varied to structurally accommodate said tubular front portion and said rear portion.
