DESIGN OF ANTISKID SOLE OF SHOES WITH REMOTE CONTROL OF STUDS MOVEMENT Russian patent published in 2011 - IPC A43C15/00 

FIELD: personal use articles.

SUBSTANCE: shoe antiskid devices. Device comprises a remote control unit separated from shoes, which transmits a radio signal of studs lifting-lowering to a control unit placed in a heel part of shoes, comprising a system for transformation of the received signal into the control signal for a step motor, a source of supply, both for the control device and the step motor, the latter, receiving the control signal and power supply, is designed to drive studs via a transmission gear, and studs are installed in heel cavities and are placed in individual functional units. On shaft of the step motor a pulley is fixed, which is profiled for a toothed belt, a doubled toothed belt and a toothed belt are connected to the pulley, and the belts actuate a set of pairs (pulley-nut)-stud, arranged in heel and toe-bunch parts of a shoe sole, external surfaces (pulleys-nuts), profiled for toothed belts, (pulley-nut) in a pair with the stud when turned away from the toothed belt lifts and lowers the stud by means of thread that connects (pulley-nut) with the stud, at the same time (pulley-nut) with its upper plane rests against the plate with axis adhered to the lower surface of the sole, on which (pulley-nut) is freely placed, and with the lower plane (pulley-nut) rests against the board of material, which provides only for a rotary motion of the nut, and the stud in the lower part has an oval profile, which enters the oval hole of the plate, adhered to the sole, thus its possible motions are only lifting and lowering.

EFFECT: device makes it possible to remotely bring shoe antiskid studs into working position and to return them into initial position.
