Arrow gun with controlled retention force and barrel vibration damping
First Claim
Patent Images
1. 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 intermediate the fixed connection and the free end of the barrel.

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.

10. An arrow gun using compressed gas to propel an arrow having a hollow portion, the arrow gun comprising:
-
(a) a barrel sized to be received within the hollow portion of the arrow, the barrel extending along a longitudinal axis; (b) a barrel adapter receiving a section of the barrel, the barrel adapter including; (i) a coupling length operably connecting the barrel to the barrel adapter, and (ii) a gripping surface configured to exert a first retention force on the arrow receiving the barrel within the hollow portion; and (c) a damping coupling contacting the barrel adapter and an outer surface of the barrel, the damping coupling disposed longitudinally intermediate the coupling length and the gripping surface. - View Dependent Claims (11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 23, 24, 25)
