US12553695 - Archery broadhead and related method of use

An expandable broadhead is provided with a ferrule defining a slot within which one or more blades are moveably mounted to a pin. A retainer in the slot can secure the blades in a closed mode when an arrow associated with the broadhead is shot from an archery bow. The retainer can include a dimple and a blade can include a retainer hole within which the dimple nests to secure the blade. The retainer hole can be common with and/or extend from a mass reducing opening defined by the blade. The dimple can ride over contours of the blade on a path to enter the hole with significantly less force than that to release the dimple and retainer from, and deploy, the blade. The slot can increase in depth beyond the dimple to reduce frictional engagement of the blades with slot sidewalls during deployment. A related method is provided.

The patent describes an expandable archery broadhead featuring a ferrule with a slot that houses a movable blade, secured by a retainer with a dimple that fits into a hole in the blade to keep it closed during flight. This design allows for easier deployment of the blade upon impact with reduced friction, enhancing the broadhead’s effectiveness.

Claim 1

1 . An expandable archery broadhead comprising: a ferrule including a forward tip and a stem configured to join the ferrule with an arrow, the ferrule defining a slot having a depth and a width, the slot bounded by a first slot sidewall; a first blade movably disposed in the slot, the first blade including an impact edge, a cutting edge and a rearward edge opposite the cutting edge, the first blade defining an elongated opening continuous with an inlet extending to a first retainer hole defined by the first blade; a pin extending through the elongated opening and secured to the ferrule so that the first blade is moveably secured to the ferrule in the slot; and a retainer disposed in the slot and including a first arm having a first dimple, the first dimple being forward of the pin and rearward of the impact edge when the first blade is in a closed mode; wherein in the first dimple is disposed in the first retainer hole providing a force on the first blade to secure the first blade in the closed mode in the slot. a ferrule including a forward tip and a stem configured to join the ferrule with an arrow, the ferrule defining a slot having a depth and a width, the slot bounded by a first slot sidewall; a first blade movably disposed in the slot, the first blade including an impact edge, a cutting edge and a rearward edge opposite the cutting edge, the first blade defining an elongated opening continuous with an inlet extending to a first retainer hole defined by the first blade; a pin extending through the elongated opening and secured to the ferrule so that the first blade is moveably secured to the ferrule in the slot; and a retainer disposed in the slot and including a first arm having a first dimple, the first dimple being forward of the pin and rearward of the impact edge when the first blade is in a closed mode; wherein in the first dimple is disposed in the first retainer hole providing a force on the first blade to secure the first blade in the closed mode in the slot.
