ABSTRACT:
A back pack carries a self-contained motor and air pump, the air intake of the pump connected to a right and left hand linearly expandable and contractable hoses having sealed free ends attached to gloves. The pump draws air from the closed hose, causing the hose to linearly contract and thereby aids the skier in pulling himself past his hand-held ski poles. A pressure switch in one or both gloves activates a solenoid that opens a valve near the pump air intake, breaking the suction in the hoses and allowing the skier to reach forward, stretching the hose, and plant his poles for another pulling motion. A flow divider in association with the valve aids in relieving suction on the hose when the valve is open. A special interlocking coaxial plug connects the glove to the hose and wires from the plug to the solenoid are incorporated in the hose in a spiral pattern for spring-like flexture with the expanding and contracting hose.
