Abstract
A helical spring has one end extending at right angles to the axis of the spring and affixed to a support platform and another end extending at right angles to the axis and at right angles to the one end and perpendicularly to the plane of the platform. A handle is provided at the other end of the spring. A meter device is coupled to the spring at the other end thereof in a manner whereby when the handle is gripped manually and moved in a direction about the axis of the spring in a plane perpendicular to the axis the meter device indicates the force applied to the handle and therefore measures the strength of the hand and arm applying the force.
Claims2
A hand and arm strength measuring device, comprising
- A support platform;
- A substantially helical spring having one end extending at substantially right angles to the axis of the spring and affixed to the platform and another end extending at substantially right angles to the axis and at substantially right angles to the one end and substantially perpendicularly to the plane of the platform;
- a handle at the other end of the spring;
- and
- meter means coupled to the spring at the other end thereof in a manner whereby when the handle is gripped manually and moved in a direction about the axis of the spring in a plane substantially perpendicular to said axis the meter means indicates the force applied to the handle and therefore measures the strength of the hand and arm applying the force.
