Abstract
A ski-pole or crutch is provided with a forearm yoke at its upper end and a pistol grip spaced below it. Both the yoke and pistol grip face rearward so that when the pistol grip is held in one hand the yoke can be swung into and out of locking engagement with the upper side of the forearm simply by bending the wrist, thereby providing greater maneuverability of the pole and support of the arm when needed for balance, support of the body and steering by planting the pole or dragging it.
Claims3
A ski-pole or crutch comprising
- an elongated shaft defining a longitudinal axis,
- a U-shaped forearm-rest or yoke rigidly mounted adjacent one end of said shaft with the legs of said forearm-rest extending from said shaft transversely of said axis in a rearward direction, said legs being spaced from each other by a distance suitable for cradling the forearm of the user and substantially symmetrical relative to the fore-and-aft plane through said longitudinal axis in said direction, and
- a pistol-grip handle rigidly mounted on said shaft and extending laterally therefrom generally in said rearward direction, said handle being spaced from said forearm-rest in the direction of the other end of said shaft and inclined toward said forearm-rest at an angle to said shaft, such that when it is gripped by the hand of the user with the thumb adjacent said shaft and in a natural attitude with respect to the forearm, said longitudinal axis of said shaft is disposed substantially parallel to the forearm,
- said forearm-rest being adapted and arranged to supportingly engage the forearm of the user when his hand is in said natural attitude and to be moved free of said forearm upon bending the wrist in a direction in which the little finger of the hand is nearer the wrist
- wherein said shaft comprises a tubular shaft member at said one end on which said forearm-rest and said pistol-grip handle are mounted and a lower shaft member telescopically received within said tubular member for adjusting the length of said ski-pole or crutch, said tubular member being split longitudinally adjacent its end into which said lower shaft member telescopes, and said pistol-grip mounting means comprising a sleeve on which said handle is fixed, said sleeve being at least partially split longitudinally and surrounding the split portion of said tubular member, and a clamp for squeezing said sleeve in order to fix said pistol-grip handle on said shaft and simultaneously to fix said lower shaft member with respect to said tubular shaft member.

- an ice-pick member mounted on said pistol-grip handle for movement between a sheathed position within said handle and an exposed position rearward of said handle for cooperation with said handle and said forearm-rest in braking and stopping the user on a steep incline.

- wherein a portion of said shaft comprises the barrel and receiver of a gun with the receiver disposed adjacent said one end of said shaft and the barrel pointing toward the other end, said pistol-grip handle being mounted on said receiver for operating the gun when skiing.
