Benefits of technology

[0010]In some embodiments according to this invention, the actuator is slideably mounted within a channel of the blade carrying body. At least a portion of the actuator interferes with or contacts the target material and moves each blade from the closed position to the opened position as the arrowhead impacts and moves through the target material. The actuator moves the blade from the closed position to the opened position upon impact, to better cut the target material.

Problems solved by technology

In many arrowheads, having relatively large portions of the blade exposed during flight results in undesirable aerodynamic steering of the arrowhead.

Embodiment Construction

[0020]FIG. 1 shows arrowhead 20 in a closed position and FIG. 2 shows arrowhead 20 in an opened position, according to one embodiment of this invention. As shown in FIG. 2, cutting diameter 22 is greater in the opened position than cutting diameter 22 in the closed position, as shown in FIG. 1. A smaller cutting diameter 22 can result in better aerodynamic qualities and flight characteristics for the arrow.

[0021]Increasing cutting diameter 22 by moving blade 40 from the closed position to the opened position just before, after and / or simultaneously with target impact and / or penetration can provide arrowhead 20 with both relatively good in-flight characteristics and relatively good cutting characteristics, particularly when each blade 40 is opened to cutting diameter 22 as shown in FIG. 2.

[0022]FIG. 1 shows actuator 50 in a forward position. FIG. 2 shows actuator 50 in a rearward position. As shown in FIGS. 1 and 2, the forward and rearward directions are relative to a forward flight...

Abstract

A blade opening arrowhead having an actuator moveably mounted with respect to a blade carrying body. The actuator can move each blade between a closed position and an opened position. During flight, the blade is in the closed position. Upon target penetration, for example, the actuator moves the blade into the opened position.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a blade opening arrowhead having an actuator that can operate one or more movable blades, each between a closed or in-flight position and an opened or cutting position.[0003]2. Discussion of Related Art[0004]Many conventional arrowheads have blades that remain in a closed position during an arrow flight and then are opened upon contact with a target. Some known arrowheads use a target material to provide resistance and thus force open or move each blade from the closed position to the opened position. For example, Mizek, U.S. Pat. No. 6,398,676 teaches a blade opening arrowhead.[0005]Many conventional arrowheads require relatively large portions of the blade to stick out or extend beyond an outer surface of a ferrule or a blade body, so that the blades open upon impact rather than the blades not opening upon impact and passing through the target in the closed position. In many arrowheads, havin...
