Abstract

Abstract A ski pole handle which includes a main gripping portion defined by an upstanding elongated body having upper and lower body portions, opposite inboard and outboard lateral faces and opposite forward and rear faces; a generally tubular thumb-receiving channel disposed at the upper body portion, the elongated body defining a handle portion disposed beneath the thumb-receiving channel and being adapted to accommodate and be gripped between a skier's fingers and palm, the thumb-receiving channel having an inner bottom thumb-supporting generally convexly curved surface merging with the rear face whereby a person's thumb and particularly the phalanges, metacarpus and the associated ulnar collateral ligament of the metacarpophalangeal joint are protected against injury normally attributed to abduction/extension of the thumb which is the usual cause of typical collateral ligament injury resulting from a skiing fall, a pair of laterally outboard knuckle-protecting sheets, one ascending and depending to collectively define with the handle portion a protective area within which is disposed the knuckles of a skier's hand, and the lower body portion defining an upwardly facing edge along the forward, rear and outboard lateral faces for supporting the hypothenar surface of the skier's hand.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 295 words
A ski pole handle comprising a main gripping portion defined by an upstanding elongated body having upper and lower body portions, opposite inboard and outboard lateral faces, a forward face and an opposite convexly curved rear face; a generally tubular thumb-receiving channel disposed at said upper body portion, said elongated body defining a hand-grip portion disposed beneath said thumb-receiving channel and being adapted to accommodate and be gripped between a skier's fingers and palm, said thumb-receiving channel having an inner bottom thumb-supporting generally convexly curved surface merging in continuity with said convexly curved rear face whereby a skier's thumb and particularly the phalanges, metacarpus and the ulnar collateral ligament of the metacarpophalangeal joint are protected against injury normally attributed to abduction/extension of the thumb which is the usual cause of typical collateral ligament injury resulting from a skiing fall; said thumb-receiving channel includes a rear-entry opening through which a person's thumb is inserted into said thumb-receiving channel and a front opening through which a person's thumb is visible when seated within said thumb-receiving channel; said thumb-receiving channel being additionally defined by a pair of spaced inboard and outboard lateral walls, said outboard lateral thumb-receiving channel wall merging progressively downwardly with a juncture surface between said rear face and said outboard lateral face, a laterally outboard knuckle-protecting sheath ascending both laterally and forwardly from said body lower portion, a laterally outboard knuckle-protecting sheath depending both laterally and forwardly from said thumb-receiving channel, said sheaths having spaced adjacent edges of sufficient flexibility for permitting the release therethrough of a skier's hand during a severe skiing fall, and means at said lower body portion defining an upwardly facing ledge along said forward, rear and outboard lateral faces for supporting the hypothenar surface and fingers of a skier's hand.
Claim 2
Dependent Claim 295 words
A ski pole handle comprising a main gripping portion defined by an upstanding elongated body having upper and lower body portions, opposite inboard and outboard lateral faces, a forward face and an opposite convexly curved rear face; a generally tubular thumb-receiving channel disposed at said upper body portion, said elongated body defining a hand-grip portion disposed beneath said thumb-receiving channel and being adapted to accommodate and be gripped between a skier's fingers and palm, said thumb-receiving channel having an inner bottom thumb-supporting generally convexly curved surface merging in continuity with said convexly curved rear face whereby a skier's thumb and particularly the phalanges, metacarpus and the ulnar collateral ligament of the metacarpophalangeal joint are protected against injury normally attributed to abduction/extension of the thumb which is the usual cause of typical collateral ligament injury resulting from a skiing fall; said thumb-receiving channel includes a rear-entry opening through which a person's thumb is inserted into said thumb-receiving channel and a front opening through which a person's thumb is visible when seated within said thumb-receiving channel; said thumb-receiving channel being additionally defined by a pair of spaced inboard and outboard lateral walls, said outboard lateral thumb-receiving channel wall merging progressively downwardly with a juncture surface between said rear face and said outboard lateral face, a laterally outboard knuckle-protecting sheath ascending both laterally and forwardly from said body lower portion, a laterally outboard knuckle-protecting sheath depending both laterally and forwardly from said thumb-receiving channel, said sheaths having spaced adjacent edges of sufficient flexibility for permitting the release therethrough of a skier's hand during a severe skiing fall, and means at said lower body portion defining an upwardly facing ledge along said forward, rear and outboard lateral faces for supporting the hypothenar surface and fingers of a skier's hand.

Claim 5
Dependent Claim 26 words

Claim 7
Dependent Claim 26 words
