EXTERNAL HUMAN UPPER EXTREMITIES SKELETON DEVICE USABLE WITH COMPUTER OPERATOR ARMCHAIR

摘要

FIELD: medical engineering.;SUBSTANCE: device has arm, elbow and hand support member cantilever, hinge, bed, spring, fixing member, movable cantilever, damper, upper and lower hinges and platform. The cantilever is fixed on armchair back. The arm support member is designed as rod having its upper part axially rotatably mounted in the cantilever. The elbow support member is designed as spreader beam. The hinge connects the spreader beam middle portion to the lower rod portion. The bed is designed as lath having arrest member mounted on the spreader beam and is movable along its surface. The hand support member is attached to frontal part of the lath and is movable forward. One of spring ends is fixed on armchair cantilever and the other one on the upper rod portion. The fixing member movable in axial direction is coaxially mounted on the rod. The movable cantilever is designed as bushing coaxially mounted on the rod and movable along it. The upper hinge connects the lower damper end to the end part of the spreader beam, fixing it in given position. The platform rotatable in horizontal plane within 90°, is articulated to the frontal spreader beam part.;EFFECT: reduced computer operator fatigability.;5 cl, 1 dwg
