Martial-arts breaking-board holder
| Details |
Inventors: Kirchner, Daniel J.;

A breaking-board holder that consists of two parallel support arms slidably and rotatably mounted on a bar that is firmly anchored to a solid structure, such as a wall or a floor. Each support arm comprises a transverse groove adapted to receive and hold the edge of a conventional martial-arts breaking board, so that the two arms together can be used to hold a board firmly in place. Because the arms are slidably mounted on the bar, the distance between them can be adjusted to accommodate boards of different sizes and users of different heights. Similarly, because the arms are rotatably disposed on the bar, the position of the board can be adjusted to face the direction needed for a given exercise. In order to facilitate the release of the board after breakage, the inner sides of the grooves in the support arms are beveled, which permits the inward folding of the board parts as they are taken apart by the blows exerted on them. |

DETAILED DESCRIPTION One objective of this invention is a self-contained breaking-board holder that can be used to practice martial-arts blows resulting from hand, elbow and foot strikes taken from multiple directions.
Another goal of the invention is a holder that is firmly anchored to a stationary structure to provide the necessary resistance to a blow to cause the breaking of the board held within it upon impact.
Yet another goal is a board holder that can be adjusted vertically to conform to the requirements of different exercises and different-height users.
Another objective of the invention is a holder that is also adjustable in width, so that it can be used interchangeably with boards of different dimensions.
A further objective is a holder that can be used with up to three boards at the same time.
A final objective is the easy and economical manufacture of the invention according to the above stated criteria.
This is achieved by using commercially available materials and manufacturing processes, modified only to the extent necessary to fit the requirements of the invention.
Therefore, according to these and other objectives, the present invention consists of two parallel support arms slidably and rotatably mounted on a bar that is firmly anchored to a solid structure, such as a wall or a floor.
Each support arm comprises a transverse groove adapted to receive and hold the edge of a conventional martial-arts breaking board, so that the two arms together can be used to hold a board firmly in place.
Because the arms are slidably mounted on the bar, the distance between them can be adjusted to accommodate boards of different sizes.
Similarly, because the arms are rotatably disposed on the bar, the position of the board can be adjusted to face the direction needed for a given exercise.
In order to facilitate the release of the board after breakage, the inner sides of the grooves in the support arms are at least partially beveled, which permits the inward folding of the board parts as they are taken apart by the blows exerted on them
