Abstract

An arrow gun is provided having a controllable retention force on the arrow. By setting the retention force on the arrow, increased energy from motive compressed gas can be imparted to the arrow. The arrow gun also includes a damping coupling for reducing vibration of an unsupported length of the barrel.

First claim

The invention claimed is:

1. An arrow gun using compressed gas to propel an arrow having a hollow portion, the arrow gun comprising:
(a) a receiver;
(b) an elongate barrel having a longitudinal axis, the barrel connected to the receiver at a fixed connection, the barrel having an outer diameter sized to be slidably received within the hollow portion of the arrow and terminating at a free end; and
(c) a damping coupling contacting the receiver and the barrel, the damping coupling longitudinally spaced along the barrel from the fixed connection to be longitudinally intermediate the fixed connection and the free end of the barrel.

2. The arrow gun of claim 1 , wherein the damping coupling is a resilient coupling.

3. The arrow gun of claim 1 , wherein the damping coupling includes at least one resilient element contacting the receiver and an outside surface of the barrel.

4. The arrow gun of claim 1 , wherein the receiver includes a barrel adapter having an aperture size to slidably receive a length of the barrel, the damping coupling extending between the barrel adapter and the barrel.

5. The arrow gun of claim 1 , wherein the fixed connection connects the receiver to the barrel.

6. The arrow gun of claim 1 , wherein the barrel has an outside diameter less than 0.5 inches.

7. The arrow gun of claim 1 , wherein the barrel has an unsupported length of 12 inches to 36 inches between the damping coupling and the free end.

8. The arrow gun of claim 1 , wherein the barrel is free of contact with the receiver along the longitudinal axis between the damping coupling and the fixed connection.

9. The arrow gun of claim 1 , further comprising a gripping surface connected to the receiver and sized to releasably engage an outer surface of the arrow.

10. The arrow gun of claim 9 , wherein the damping coupling is longitudinally intermediate the gripping surface and the fixed connection.

11. An arrow gun using compressed gas to propel an arrow having a hollow portion, the arrow gun comprising:
(a) an elongate barrel having a longitudinal axis, the barrel connected to the arrow gun at a fixed connection, the barrel having an outer diameter sized to be slidably received within the hollow portion of the arrow and terminating at a free end; and
(b) a damping coupling contacting the barrel, the damping coupling longitudinally spaced along the barrel from the fixed connection to be longitudinally intermediate the fixed connection and the free end of the barrel.
