BROADHEAD
A broadhead has at least two overlapping blades received within an elongated groove, each blade having a blade extension, the blade extensions extending in opposite directions.
The present disclosure relates to a broadhead with retracted blades that pivot outwardly into an expanded position upon target contact and more particularly, but not by way of limitation, to an arrow broadhead having a cutting blade housing body with an elongated groove extending along a portion of a length of the housing body. The groove is used to receive a pair of cutting blades. The cutting blades are received in opposite sides of the groove when the broadhead is in a retracted position during arrow flight. Upon target contact, the blades may pivot outwardly from the sides of the groove into an expanded position for maximum cutting and target penetration.
The accompanying drawings illustrate various embodiments for broadheads in which:
Various embodiments provide a broadhead with a pair of cutting blades in a retracted position in a groove in a cutting blade housing body during arrow flight, hold the cutting blades in an expanded, locked position during target contact, and then allow the cutting blades to fold forward for ease in release when the broadhead is pulled outwardly from the target which may make it a non-barbed design.
Other embodiments illustrate how an arrow broadhead housing can include a tip that allows detachment from the housing body. The separate, detachable tip can be attached to a top portion of the housing body, which may allow the rotating, sliding, or pivoting cutting blades to be received in the elongated groove. This feature may allow for a connected pair of blades or at least one blade to be received in an elongated groove.
Still other embodiments relate to multiple features or blade extensions on cutting blades to be received in a cutting blade housing body or elongated groove. The blade extensions can be in the form of a bend in the blade, an extrusion on the blade, a bump or outward extension from the blade, a screw in the blade, a rivet in the blade, a screw pin, a protruding portion of the blade, a molded outward portion on the blade, or other extensions. The blade extrusion can be of different shapes, sizes, and combinations thereof. This blade feature can be any makeup that creates a non-parallel portion to the blade length. This feature may allow the blade or blades to be received within the elongated groove.
Still other embodiments relate to the blade or blades extending from one side of the housing body through the other side of the housing body.
Still other embodiments relate to a pair of cutting blades crossed over one another and at least partially received in an elongated groove or slot in the housing body. The blades have a forward portion that, upon target contact, push rearwardly and move the blades outward into an expanded position for increased cutting and penetration in the target.
Still other embodiments relate to using the broadhead's forward inertia to hold the cutting blades in the elongated groove in the housing body to approximately upon target contact, then moving the cutting blades into a fully expanded and locked position. The forward inertia of the arrow broadhead and the extension of the blades may provide for an improved cutting and tissue damage to the intended target. This feature results in larger entry and exit holes in the target, better blood trails and higher game recovery.
Still other embodiments relate to various blade retention devices to hold the blades into a retracted in-flight position during arrow flight. The blade retention devices can be a steel ring, o-ring, rubber ring, half ring, plastic clip over any portion of the blades, spring ring, half ring, tension ring, tension ring pushing on blades, tension ring covering blades, tension ring pulling blades inward, tension wire, tension wire pulling on blade extrusions and keeping blades retracted, tension ring pushing against the blades, torsional spring or tension clip over a portion of the blades or pressing against the blades, of any size, shape, or combinations thereof.
In one embodiment the broadhead may include a pair of cutting blades received in an elongated groove in a cutting blade housing body. The cutting blades may be folded into a portion of the groove during arrow flight. Upon target contact, the blades may be configured to move rearward and outward from opposite sides of the groove into an expanded position for increased cutting and penetration in the target.
In some embodiments, a plurality of blades can overlap each other within a channel of a body or ferrule.
In some embodiments, blade extensions on each blade can be configured to contact and move along an outer surface of the ferrule without being confined to moving within a channel of the ferrule.
In some embodiments, providing blade extensions on one side of each blade extending in opposite directions allows the blades to overlap each other while still being able to rotate, and may further allow the blades to be kept in a smaller, gather or more compressed circumference during an in-flight position for better aerodynamics and flight. Opposing blade extensions extending from one side of each blade may further allow the blades to rotate freely from a retracted in-flight position to an extended cutting position to a non-barbed position.
In some embodiments, blade extensions may be configured to couple the blades to the housing body and may further be configured to align the blades to slide rearward into an expanded cutting position.
In some embodiments, an additional blade extension on an inner portion of the blade (extending opposite the aforementioned blade extension) and the blade slot on the opposite blade may couple the two blades together within the elongated groove of the ferrule which may allow the blades to rotate freely from a retracted in-flight position, to an extended cutting position, to a non-barbed position, while retaining the blades within the body.
In some embodiments, a broadhead body may comprise an exterior or outside bump or may have a recessed portion for the blade extensions to lock the blades into an expanded position. In some embodiments, the blade extensions are configured to hook over this portion of the body and pry against the body to lock the blades into an expanded cutting position.
In some embodiments, the blades may be coupled together and to the body without requiring the use of fasteners on the body to retain the blades.
In some embodiments, the blade extension may be removable to allow the blades to be inserted in a body or elongated groove without having a slot completely through the end of the body or without having to remove a tip to insert the blades.
The various features of the embodiments disclosed herein show novel construction, combination, and elements as described, and more particularly defined by the claims, it being understood that changes in the embodiments to the disclosed invention are meant to be included as coming within the scope of the claims.

Also shown in this front view are cutting blades 6 and 7 received in housing body 2 and overlapping one another in at least one position and optionally in all positions of the movable blades. The cutting blades 6 and 7 are illustrated each with an extension 13 and 14 that protrudes outward in opposite or opposing directions so the blades 6 and 7 can slide or rotate. Extensions 13 and 14 may extend normal, perpendicular, or transverse to a major plane defined by the respective blade of each extension. The extensions 13 and 14 may help align and retain the blades 6 and 7 within the housing body 2. Extensions 13 and 14 can be of various shapes and sizes and may compromise an addition, protruding portion, bend, rivet, screw, pin, extrusion, nut or bolt, forged metal or composite, removable or detachable from blade, permanent, integrally formed with the blade, or any combination thereof. Each of blades 6 and 7 can also have multiple extensions to retain the blade or blades within the elongated groove 21 of housing body 2 (e.g., one extension disposed on each opposing side of groove 21, or other configuration). There may also be a member or extension 15 on blade 7 that protrudes in the opposite direction of extension 14. This member 15 is received in receiving slot 11 of blade 6. The member 15 and slot 11 may help couple blades 6 and 7 together. Blade member 15 can also be various shapes, sizes, permanently fixed to blade, forged to blade, a blade extension, removable or detachable from a blade, a loose shape piece of any shape, bump, a protruding portion, rivet, screw, pin, extrusion, nut or bolt, bend or any combination thereof. The slot 11 can also be of various shapes, sizes, open, closed and different combinations thereof. In this embodiment, slot 11 is substantially v-shaped. Blade extensions can be received in slots that are in different locations on or in housing body 2, for example in a top end portion, a middle portion, a bottom end portion, etc. In some embodiments, blade 6 and/or blade 7 may have an extension on only one side of the blade and not on both sides of the blade.
