BOOT FOR THE MECHANICAL MOVEMENT OF THE SOLE

摘要

Constitution-function: A steady body embracing the tibia bone (leg) up to the knee level (1), which body is externally firmly retained by self-adhesive straps (2), internally lined with foamy material or -occasionally- with an elastic tibia sock (3) and provided with a sole extending from ankles level to toes (4) and moving via articulation on the body (5). The movement of the sole is ensured either by a 12-v power source or by a 220-v power source; a transformer converts ac current into dc current (from 220v to 12v); said power sets into operation -via electric coils (8)- the shaft (9) whereto there is adapted a rotary disc (10) having two holes (11) lengthwise its radius in which holes there is adapted a shaft ending with an articulation at the outer surface of the sole (12). The rotation of the disc causes the displacement of the shaft setting, in turn, into motion the sole. The eccentric movement of the holes existing on the disc displaces the firm shaft in an oscillatory mode so that the oscillatory displacement of the sole by 20-40 deg. is ensured with regard to what hole of the disc the shaft is adapted (in proximity to the centre of thedisc or at the periphery thereof).
