Detector indicating pressure applied by legs during walking - includes fluid filled flexible support communicating with pressure gauge via non-return valve

摘要

The equipment indicates the pressure exerted by a leg on the ground during e.g. walking. It comprises a hollow support made of e.g. vinyl chloride which is filled with a transmission liquid. The liquid drives a measuring and control device situated above the support. The control comprises an anti-return valve (6), a direct reading manometer (8) and a manually operated gate (7). The sensitivity of the pressure gauge (9) can be changed by a screw (10) which exerts a pressure on the reservoir (B) via a spring (11).
