Broadhead arrow tip release mechanism

摘要

A broadhead tip for an arrow having moveable broadhead knives that remain in a first position during flight, extend to a second position when a reverse direction force is applied to the arrow (such as by trying to extract the arrow from the target) that is generally radially oriented to the arrow to prevent removal of the broadhead tip from the target. A barrel stop disposed on the arrow is rotatable between locked and released positions and engages the knives. When locked, the knives are limited to movement between the first and second positions. When released, the knives are permitted to pivot beyond the radial orientation, to a third position approaching 180 degrees from the first position which then allows the knives to swing around so that the broadhead can be removed from the target. Primary use for the broadhead tip is archery fishing.

主权项

1. A tip for an arrow comprising:
a core portion; a retainer portion having a plurality of swingable blades each with a proximal end pivotally connected to the retainer portion, each blade swingable between generally opposing first and second positions, the retainer portion being rotatable in relation to the core portion and rotatable about a longitudinal axis of the arrow to at least a locked position and released position; and a locking member to restrain the retainer portion in at least one preferred position; the core portion further including a stops surface engaging the blades to prevent movement toward the second position from an intermediate position between the first and second positions when the retainer portion is in the locked position, the core portion further including a release surface that allows the plurality of swingable blades to move freely between the first and second positions when the retainer portion is in the released position.
