Magnetic blade retainer for a broadhead

摘要

A magnetic blade retainer for an expandable broadhead utilizing the properties of magnetic attraction to reliably secure a plurality of blades completely within respective blade channels so that an expandable broadhead may closely resemble the flight properties of a practice arrow tip yet lethally expand upon impact with a target. Extraneous parts are eliminated, but a strong, disc magnet is inset or integrated into the forward portion of a broadhead tip assembly. Each blade is provided with a magnetic, flat forward end. The interaction of the flat forward end and the magnet magnetically retain each blade. The magnetic bond is broken when the arrow penetrates a target. An actuating spike further transfers the impact energy to each blade. The forces on the actuating spike then drag each blade backward and each blade extends as the rearward forces are translated by the wedging surface near the end of the channel.

主权项

1. A blade retainer for a broadhead, the blade retainer comprising:
a blade having a flat face, a magnet disposed in the broadhead, wherein the magnet holds the blade in position by forces of magnetic attraction between the magnet at the flat face of the blade, and wherein the flat face is perpendicular to a broadhead flight path.
