Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 188 words
A ski pole having an upper handle end portion and a lower basket end portion; said handle end portion being tubular and affording a socket which opens at the upper end of said pole; said basket end portion being solid; said socket being defined by a peripheral wall; said wall having a radially inwardly projecting step spaced axially inwardly from the upper end of said pole and external screw threads disposed on said upper handle end portion; a signal device disposed within said socket and retained against downward movement by said step; signal energizing means disposed in said socket above said signal device; a handgrip having an internally threaded cavity whereby said handgrip is detachably thread fitted to said handle end portion; a manually movable actuator member carried by the upper end of said handgrip, said energizing means responsively connected to said actuator member for causing said energizing means to actuate said signal device; said wall including means affording transmission of said signal outwardly of said ski pole, and said signal device is adapted to produce a visual warning signal in response to movement of said actuator member.
Claim 2
Dependent Claim 188 words
A ski pole having an upper handle end portion and a lower basket end portion; said handle end portion being tubular and affording a socket which opens at the upper end of said pole; said basket end portion being solid; said socket being defined by a peripheral wall; said wall having a radially inwardly projecting step spaced axially inwardly from the upper end of said pole and external screw threads disposed on said upper handle end portion; a signal device disposed within said socket and retained against downward movement by said step; signal energizing means disposed in said socket above said signal device; a handgrip having an internally threaded cavity whereby said handgrip is detachably thread fitted to said handle end portion; a manually movable actuator member carried by the upper end of said handgrip, said energizing means responsively connected to said actuator member for causing said energizing means to actuate said signal device; said wall including means affording transmission of said signal outwardly of said ski pole, and said signal device is adapted to produce a visual warning signal in response to movement of said actuator member.
Claim 3
Dependent Claim 45 words
A ski pole as set forth in claim 1 wherein said signal device comprises an electric bulb; said socket wall comprising light transmittable material whereby the light from said electric bulb causes at least a portion of said ski pole to glow in the dark.
