Abstract

A pneumatic tube that is secured to the bow and bowstring with an arrow and piston inside for safe drawing and firing of an archery bow. When the archer looses the string and it drives the arrow forward, the piston creates pneumatic air resistance like a hand operated bicycle pump. This resistance is sufficient to prevent damage to the bow and/or its components from loosing the string without an actual arrow on the string. Normal loosing the string without an arrow on it is called “dry-firing” and would damage the bow and/or its components. This tube is attached to a bracket that is affixed to a mounting block that can be fastened to the front of the bow at the standard stabilizer mounting hole. There is also a laser mounted in the end of the tube, which can be turned on by the archer and projects a laser light on the target. This light is automatically turned off as the bow is fired, thus showing the archer exactly where an actual arrow would have hit. This device can be used without removing or disabling the arrow rest and is used in practice and to identify and then rectify any release flaws and other shooting maladies.

Claims

1. An archery training device that attaches to a bow and consists of a pneumatic tube with a substitute arrow attached to a bow string on one end, and a piston on the other end, and as the string is drawn back and released, the substitute arrow and piston drives forward into the pneumatic tube, the piston fits inside the diameter of the tube tight enough to create resistance, which lets the bowstring down slow enough as to not damage the bow, and the forward driving piston causes a considerable air blast which is channeled through a small hole in an end plug of the tube;

ahead of the plug there is second section of tubing that houses a small laser with an on/off button and this laser is secured at a forward end to the second section of tubing;

a hollow sleeve with one closed end fits over a back end of the laser, and there is a lever affixed to the sleeve that protrudes on the outside of the second section of tubing, so the archer can pull back on the lever which slides the sleeve over the on/off button on the laser housing, which depress the button and turns on the laser, which projects an intense light on the intended target by which the archer can then practice aiming and firing a bow without arrows and without damage to the bow or injury to the archer.

2. The archery training device as described in claim 1, in which the laser projects a dot which is turned off automatically when the bowstring is released and the air blast from the piston hits a sealed flat end of the sleeve that covers the laser on/off button and said sleeve is blown forward off and away from the on/off button at which time the archer can then tell where he was aiming and predict where a real arrow would have gone by noting at what point and at what location on the target the laser dot went off and then the archer can slide the lever back to turn on the laser light and repeat the above process over and over, noting any jerking or lateral movement of the laser light just before it goes off, which allows the archer opportunity to change his style or method of shooting so that the light goes out while on target smoothly.

3. The archery training device as described in claim 1, further including a bracket that attaches the pneumatic tube to the front of the bow in the following manner:

a small block with a bolt hole in it is secured to the front of the bow with a bolt at a right angle to and below the handle in a hole designed to screw on a front stabilizer;

two opposing sides of said block have a groove in them that allows a vertical bracket with several adjustment holes to be affixed to either side, to accommodate right-handed or left-handed archers, and said bracket rises at an angle of 10 degrees or more in relation to the bow handle, which angles the at away from the archers hand so as not to interfere with said hand;

on the top end of said bracket is affixed a clamp that secures around the pneumatic tube and keeps it in place while the bow is dawn and fired.

4. The archery training device as described in claim 3, in which the block and attached bracket is mounted so as to be removable and replaceable on the bow.

5. The archery training device as described in claim 3, in which the block includes a removable piece that has a threaded hole for mounting a stabilizer, while the archery training device is attached to the bow.
