EXPANDABLE BROADHEAD WITH REAR DEPLOYING BLADES
First Claim
Patent Images
1. An expandable broadhead comprising:
- a broadhead body comprising a longitudinal axis and at least one blade recess;
a plurality of rear deploying blades residing at least in part in the at least one blade recess and slidingly engaged with the broadhead body, the blades each comprising a cutting edge exterior from the broadhead body when in a retracted configuration, and a camming surface effecting a camming action during deployment of the blades from the retracted configuration to a deployed configuration; and
a shock-absorbing retainer releasably engaged with at least one feature on the rear deploying blades to retain the rear deploying blades in the retracted configuration, the retainer positioned to engage with the rear deploying blade in the deployed configuration.

Abstract
An improved expandable broadhead with rear deploying blades. The rear deploying blades deploy reliably upon impact of the blades with a target. The expandable broadhead resists deflection by the target regardless of the angle of entry. Consequently, the present expandable broadhead maximizes kinetic energy on impact and increases the probability of substantial penetration into the target.

17. An expandable broadhead comprising:
-
a broadhead body comprising a longitudinal axis and a plurality of blade recesses; and a plurality of rear deploying blades each comprising an elongated slot slidably engaged with a feature on the broadhead body, the slots comprising a first end, a second end, and a free floating region between the first and second ends, the blades each comprising a cutting edge exterior from the broadhead body when in a retracted configuration, and a camming surface effecting a camming action during deployment of the blades from the retracted configuration to a deployed configuration.

18. An expandable broadhead comprising:
-
a broadhead body comprising a plurality of blade recesses; a rear deploying blade located in each of the blade recesses, the rear deploying blades comprising elongated slots, cutting edges exterior from the broadhead body when in a retracted configuration, and camming surfaces effecting a camming action during deployment of the blades from the retracted configuration to a deployed configuration; and pivot features extending into the blade recesses and through the elongated slots to slidably attach the blades to the broadhead body, such that upon impact of the expandable broadhead with an object the elongated slots slide relative to the pivot features, the blades translate rearwardly relative to the broadhead body along a deployment profile, and rear ends of the blades move radially outward to the deployed configuration. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
