Load indicator detecting patient's weight on walking crutch - has switch with deformable elastic element and inclination switch operating warning light when load is exceeded

摘要

The device signals when a force applied to the support exceeds a preselected value, for testing the load on the leg of a patient being rehabilitated. An intermediate elastic element is connected with the clutch support. Its deformation is proportional to the force applied longitudinally to the support. a displacement pick-up measures the above elastic element deformation, and when a preselectable deformation is exceeded, it connects a voltage source to a signalling device, if at the same time an inclination switch connected with the crutch support is within a suitable angle.
