Abstract
Abstract A device for the improvement of the guidance of a pair of skis, the device comprising an upstanding ridge means disposed on the upper surface of the forward portion of each ski directly along the edge thereof nearest to the adjoining ski of the pair whereby, lateral guidance of skis, particularly of skis having small thickness, is greatly improved and their superimposition or crossing during running is obviated.

Claim 1
Independent Claim
155 words
A device for the improvement of the guidance of a pair of skis, each ski including a forward portiOn possessing an upwardly directed tip, said device comprising an upstanding ridge means disposed on the upper surface of the forward portion of each ski rearwardly of the upwardly directed tip thereof and directly along an edge thereof nearest to the adjoining ski of the pair, and means for securing each of said ridge means to each ski such that the elastic properties of the skis remain practically unchanged, each of said ridge means comprising a plurality of upstanding members attached to one ski of the pair in tandem spaced relationship along said edge, the height of each of said members being no greater than the thickness of the ski to which it is attached, said ridge means counteracting the tendency of the skis during skiing to cross one another without impairing parallel travel of the skis.
Claim 2
Independent Claim

A device for the improvement of the guidance of a pair of skis, each ski including a forward portiOn possessing an upwardly directed tip, said device comprising an upstanding ridge means disposed on the upper surface of the forward portion of each ski rearwardly of the upwardly directed tip thereof and directly along an edge thereof nearest to the adjoining ski of the pair, and means for securing each of said ridge means to each ski such that the elastic properties of the skis remain practically unchanged, each of said ridge means comprising a plurality of upstanding members attached to one ski of the pair in tandem spaced relationship along said edge, the height of each of said members being no greater than the thickness of the ski to which it is attached, said ridge means counteracting the tendency of the skis during skiing to cross one another without impairing parallel travel of the skis.
Claim 3
Independent Claim
144 words
A device for the improvement of the guidance of a pair of skis, each ski including a forward portion possessing an upwardly directed tip, said device comprising an upstanding ridge means disposed on the upper surface of the forward portion of each ski rearwardly of the upwardly directed tip thereof and directly along an edge thereof nearest to the adjoining ski of the pair, and means for securing each of said ridge means to each ski such that the elastic properties of the skis remain practically unchanged, each of said ridge means comprising an elongated member, means adjacent each end of said ridge member for detachably and flexibly securing said ridge member therebetween adjacent to the upper surface of its associated ski, said ridge means counteracting the tendency of the skis during skiing to cross one another without impairing parallel travel of the skis.
