Abstract

An adjustable target holder for martial arts training has a base, a vertical support post and an elongated bi-sectional arm. The first arm is hollow, is slidably attached to the post, and has an open distal end. The second arm is solid and includes an extension received in the first arm'"'"'s hollow interior. The second arm extension rotates inside the first arm. The second arm is rotated and locked into a selected position by means of a push button and follower detent which is urged into one of a series of depressions in the first arm'"'"'s interior. The second arm'"'"'s distal end includes a chamber into which a target end is placed. The target end is held firmly in the second arm by wedges which are positioned by a rack and pinion. When a handle operably connected to the rack and pinion is turned, the wedges move to hold the target. The second arm is then rotated into a desired position, supporting the board horizontally, vertically, or diagonally.

Claims

1. An adjustable target holder for martial arts training , comprising:

a vertical support post and means to support said post to extend perpendicularly from a supporting surface;

an elongated bi-sectional arm including;

(i) a first arm having a proximal end for attachment to said post and a distal end;

(ii) a second arm, including an extending section rotatably attachable to said distal end of the first arm, one of the first arm and the extending section of the second arm having a diameter less than the diameter of the other of said first arm and the extending section of the second arm , whereby said first arm and said second arm fit within one another ;

means to slidably retain said elongated bi-sectional arm at the proximal end of the first arm on said post;

means to rotatably and lockably retain said extending section, including a plurality of identical angularly spaced depressions around a circumference of one of the first arm and the second arm, proximate the distal end of the first arm, and a spring loaded push button mounted on and extending from the other of said first and said second arm, the spring loaded push button being operably connected to a spring loaded follower, the spring loaded follower being mounted to be depressed by depression of said push button, permitting relative rotation of the first arm and the second arm, and upon release of the spring loaded push button, the spring loaded follower engaging in one of the angularly spaced depressions, fixing the second arm relative to the first arm ;

means located in said second arm to removably retain and position a target; and

,

means to prevent lateral movement of the second arm in the first arm, including a collar and collar mounting means mounted in the first arm and the extending section of the second arm, the collar and collar mounting means frictionally engaging one another to prevent said lateral movement .

2. The target holder according to claim 1, wherein said means to support the post includes a base provided with a plurality of wheels and at least one wheel locking means.

3. The target holder according to claim 1 wherein said collar mounting means includes at least one adjustable retaining pin extending transversely inward from said first arm to adjustably press against said collar to hold it in place.

4. The target holder according to claim 1 including, additionally, a washer and threaded holding pin to position said collar in said first arm.

5. The target holder according to claim 1 , wherein said means to removably retain a target in said second arm includes:

(a) a chamber in said second arm;

(b) a rack and pinion operably connected and located in said chamber;

(c) a set of two wedges , one of the wedges being operably connected to said rack on an underside thereof ; and

,

(d) a crank handle extending outwardly from said second arm and operably connected to said pinion, whereby turning of said handle relatively displaces said wedges to slide over one another and against said target in said chamber.

6. The target according to claim 5, further comprising a filler to aid in holding said target ,the filler being removably mountable in the chamber.

7. The target holder according to claim 1 including, additionally, circumferential, shock absorbing padding around each of said arms.

8. An adjustable target holder for martial arts training comprising:

a vertical support post and means to support the post to extend perpendicularly from a supporting surface;

an elongated bi-sectional arm including;

(i) a first arm having a proximal end for attachment to said post and a distal end;

(ii) a second arm, including an extending section rotatably attachable to said distal end of the first arm, one of the first arm and the second arm having a diameter less than the diameter of the other of said first arm and the extending section of the second arm, whereby the first arm and the second arm fit together;

means to slidably retain said elongated bi-sectional arm at the proximal end of the first arm on said post;

means to rotatably and lockably retain said extending section, including a plurality of angularly spaced depressions around a circumference of one of the first arm and the second arm, proximate the distal end of the first arm, and a spring loaded push button mounted on and extending from the other of said first and said second arm, the spring loaded push button being operably connected to a spring loaded follower, the spring loaded follower being mounted to be depressed by depression of said push button, thereby permitting relative rotation of the first arm and the second arm, and upon release of the spring loaded push button, the spring loaded follower engaging in one of the angularly spaced depressions, fixing the second arm relative to the first arm , said means to rotatably and lockably retain the second arm including a plate with apertures sized to receive said push button and said follower, and wherein said push button and said follower each have continuations extending through said plate , a spring being located between said continuations and said plate, one of said first arm and said second arm having a cut-away area to receive said plate and channels to receive said push button and said follower continuations.

9. The target holder according to claim 8, further comprising means to prevent lateral movement of said second arm in said first arm.
