Abstract
A hunting arrow has a wound-enhancing accessory which has at least one pair of pivoting knife blades which deploy upon striking the targeted prey. Unlike existing broad head devices, the blades of the present invention are positioned at the tail of the arrow between the fletching and the nock where there is less impact on the aerodynamics of the arrow. In one embodiment, the restraining force resisting deployment of the knife blades can be adjusted using a set screw.
Claims8
A hunting arrow adapted for hunting a prey, said arrow comprising elements interconnected seriatim:
- a) a tip;
- b) a shaft having a longitudinal axis;
- c) fletching symmetrically positioned about said axis;
- d) a broadtail accessory with deployable knife blades for enlarging a wound in the prey to ensure a kill;
- e) a nock member for engaging a string of a bow.
A broadtail accessory for a hunting arrow, said accessory comprising a cylindrical body portion adapted to be inserted in an arrow behind fletching and ahead of a nock member, said accessory including at least a pair of knife blades biased to a forward position each extending out of a slot in said cylindrical body portion and adapted to rotate outwardly and rearwardly to an extended locked position as said accessory follows said fletching into a wound in a designated prey including adjustment means to vary a biasing force exerted on said at least a pair of knife blades.
In an accessory for a hunting arrow employing a set of deployable knife blades which pivot from a first in-flight position to a second extended position useful for enlarging a wound in the prey to ensure a kill, the improvement comprising
- a) an indentation formed on an aft end of at least one knife blade;
- b) a threaded bore extending from a nock-receiving aperture in a trailing end of said accessory and a through slot extending laterally through a length of said accessory, said through slot receiving said deployable knife blades;
- c) a set screw adjustably received in said threaded bore, set screw engaging in at least one said indentation of each said knife blade;
- whereby a position of said set screw can be adjusted to vary an amount of force necessary to deploy said knife blades from said in-flight position to said extended position.
