Abstract
A blade-opening arrowhead device includes an arrowhead body having a plurality of longitudinal blade slots on an outer surface and a flexible wedge slot extending through a center portion of the body. A blade is pivotally disposable in one of the blade slots and pivotable between a retracted position and a deployed position. A flexible wedge is disposable in the flexible wedge slot. The flexible wedge is configured to apply a wedging force against the blade in the retracted position to maintain the blade in the retracted position until a sufficient external force overcomes the wedging force and pivots the blade to the open position.
Claims19
A blade-opening arrowhead device, comprising:
- a) an arrowhead body having a blade slot extending longitudinally between a rearward end toward a forward end, the blade slot having a pivot pin hole near the rearward end;
- b) a blade disposable in the blade slot and having a forward end, an opposing rearward end and a cutting edge extending therebetween, the blade having a corresponding pivot pin hole near the rearward end alignable with the pivot pin hole in the arrowhead body;
- c) a pivot pin disposable in the pivot pin hole of the arrowhead body and the corresponding pivot pin hole of the blade to rotatably connect the rearward end of the blade to the arrowhead body such that the blade is rotatable between a retracted position with the blade stowed in the blade slot and a deployed position with the forward end of the blade rotated away from the arrowhead body;
- d) a flexible wedge slot disposed in the arrowhead body and oriented substantially orthogonal to the blade slot;
- and
- e) a flexible wedge disposable in the flexible wedge slot and extending into the blade slot to contact and apply a wedging force against the blade when the blade is in the retracted position.
A blade-opening arrowhead device, comprising:
- a) an arrowhead body having a plurality of longitudinal blade slots on an outer surface and a flexible wedge slot extending through a portion of the body orthogonal to the longitudinal blade slots;
- b) a plurality of blades, each blade pivotally disposable in a different one of the blade slots and pivotable between a stowed position with the blade in the blade slot and a deployed position with the blade extending away from the arrowhead body;
- and
- d) a flexible wedge disposable in the flexible wedge slot and having a plurality of spokes with each spoke extending into one of the plurality of blade slots to contact and apply a retentive force against each of the plurality of blades in the retracted position.
A method for making a blade-opening arrowhead device, comprising:
- a) obtaining an arrowhead body;
- b) attaching a pivotal blade to the arrowhead body with the blade pivotable between a stowed position with the blade at least partially disposed within the arrowhead body and a deployed position with the blade extending away from the arrowhead body;
- and
- c) placing a flexible wedge within the arrowhead body such that the flexible wedge contacts the blade in the stowed position and wedges the blade against an opposing flexible wedge.
