PRESSURE INDICATING DEVICE

摘要

A device for indicating the pressure applied to an object by a strap (21 ). The device is adapted to receive an end of the strap and to allow the strap end to be pulled through the device against the action of a deformable spring means (22), thereby progressively increasing the pressure applied to the object. The spring means progressively deflects in proportion to that applied pressure. A linking means (24) translates the deflection of the spring means to the movement of a pointer (23) which thus provides an indication of the pressure being applied by the strap against some reference markings on the strap (25).
