Abstract
Accurate registration of the force of a blow delivered to a large-area padded target is achieved by supporting the target on a plurality of piston-and-cylinder units which are located outboard of the target outline. Resistance is provided by coil springs surrounding the pistons of the piston-and-cylinder units. Force is registered by a series of electrical switches operable by a stepped plate carried by the target. The switches actuate indicator lights through electronic delay circuitry which insures that blows, even though momentarily applied, are distinctly indicated.
Claims10
A device for use in practice of martial arts comprising:
- a rear support;
- a padded target having a strikable front surface defined by an outline at least one of the transverse dimensions of which exceeds approximately twelve inches;
- means for mounting the target on the support and constraining the target to linear movement toward and away from the support;
- resilient means connected between the target and the support for resisting movement of the target toward the support;
- and
- means, actuable by movement of the target toward the support, for establishing at least three ranges of positions of the target and for indicating the maximum extent of movement of the target when struck, by indicating in which of said ranges the target is positioned at the point of its maximum degree of movement toward the support;
- in which the means for mounting the target on the support comprises at least three piston and cylinder units, each being located exteriorly with respect to the outline of the strikable front surface of the target and in which an extension of an imaginary cylinder defined by the target outline upon said linear movement of the target falls substantially completely within a multi-sided figure formed by straight lines connecting the axes of said piston and cylinder units.

- and
- means, actuable by movement of the target toward the support, for indicating the extent of movement of the target;
- in which the means for mounting the target on the support comprises a plurality of piston and cylinder units, each being located near the outline of the strikable front surface of the target;
- and
- in which the means for indicating the extent of movement of the target includes a plurality of momentary switches, means for actuating said switches successively as the target moves toward the support, an indicator light associated with each switch and electrically connected thereto for illumination of the light upon actuation of its associated switch, and electrical delay means, associated with each indicator light, for effecting continued illumination thereof for a predetermined time interval following actuation of its associated switch.
