Arrowhead Blade Retention Device

The present application claims the benefit of priority to U.S. Provisional Patent Application No. 63/657,441, entitled “Arrowhead Blade Retention Device,” filed Jun. 7, 2024, the entirety of which is hereby incorporated by reference herein for all purposes.

The technology described herein relates generally to an arrowhead blade retention device.

Archery is the sport, practice, or skill of using a bow to shoot arrows. Archery has been used for hunting, combat, competitive sport, and recreation. The most common form of an arrow consists of a shaft, with an arrowhead at the front end, and fletchings and a nock at the other end. Arrowheads may come separate from the shaft and include target points, field points, and broadheads. Broadheads are typically wide arrow points with sharp edges for cutting and are often used for hunting. Broadheads may come with different types of blades, including fixed blades, removable blades, and expandable blades. It is desirable for an expandable broadhead to maintain a compact formation and deploy upon impact with a target; however, current expandable broadheads have difficulty maintaining this compact formation until impact and often deploy early during flight, reducing kinetic energy and the ability of the broadhead to penetrate deeply into the target.

The information included in this Background section of the specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and is not to be regarded subject matter by which the scope of the invention as defined in the claims is to be bound.

The arrowhead blade retention device may include a body, which may include a central body and a plurality of ears that extend outward from the central body. The arrowhead blade retention device may also include a plurality of blade retainers defined at least partially within the plurality of ears. The plurality of blade retainers may include retainer outer walls and may be sized to receive arrowhead blades. A plurality of lateral walls may be defined between the retainer outer walls and an outer wall of the body.

Other examples or embodiments of the present disclosure may include an arrowhead with deployable blades that includes a point, an arrowhead shaft having a first shaft end and a second shaft end, with the point coupled to the first shaft end and a base coupled to the second shaft end. The base may include a base head and a base shaft. A blade carrier may be slidably coupled to the arrowhead shaft. A plurality of cutting blades may be pivotally coupled to the blade carrier, the cutting blades including blade tips and blade cutting edges. The arrowhead may further include a blade retention device that includes a flexible body including a top wall defining a central aperture and at least two blade retainers on opposing sides of the central aperture. The base shaft may extend through the central aperture, the top wall may be positioned below the base head, and the blade tips may align with the at least two blade retainers.

The flexible body may include a top wall and a sidewall, and the top wall may define a central aperture. At least one recess may be defined in the top wall and may include a recessed surface and a recess outer wall. At least one lateral wall may be defined between the recess outer wall and the sidewall. A thickness of the at least one lateral wall is sized such that the at least one lateral wall breaks when an arrowhead blade applies force to the recess outer wall.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. A more extensive presentation of features, details, utilities, and advantages of the present invention as defined in the claims is provided in the following written description of various embodiments and implementations and illustrated in the accompanying drawings.

This disclosure is related to an arrowhead or broadhead blade retention device. The disclosed arrowhead blade retention device may include a flexible body that couples with arrowhead blades to hold the arrowhead blades in a collapsed or folded position while the arrowhead is in flight. The disclosed arrowhead blade retention device may be broken or reconfigured upon impact with a target, releasing or deploying the arrowhead blades in a deployed position. The term “target” is used herein to refer to any material the arrowhead may encounter. By holding the arrowhead blades in place in a compact configuration during flight and allowing the blades to deploy upon impact with a target, disclosed arrowhead blade retention devices maintain the kinetic energy of an arrow during flight to allow for greater impact force with and penetration through the target.

Disclosed arrowhead blade retention devices are configured to retain blades of an arrowhead that includes blades that release or deploy from a retained or collapsed position. Such arrowheads include broadheads, which have blades that open outward from a central shaft. As an example, disclosed arrowhead blade retention devices may be used with the arrowhead disclosed and described in U.S. Pat. No. 10,180,312 B2 entitled “Mechanical Expanding Broad Head Arrow Point,” granted on Jan. 15, 2019 (the '312 Patent), which is hereby incorporated by reference in its entirety.

Disclosed arrowhead blade retention devices may include a central body and a plurality of blade retainers. The blade retainers may be positioned on opposing sides of the central body. The blade retainers may be recesses, notches, apertures, grooves, slots, and the like. The blade retainers are configured to retain blades of an arrowhead, for example, by housing, surrounding, encapsulating, or otherwise holding a portion of the blades, such as the blade tips or points. Disclosed arrowhead blade retention devices may include a plurality of ears or arms that extend outward from the central body. The plurality of ears or arms may extend or curve upward from the central body. The plurality of blade retainers may be defined within the plurality of ears. The number of ears and/or the number of blade retainers may be varied to correspond with the number of blades of the arrowhead. The central body may define a central aperture that is configured to receive a shaft of the arrowhead. For example, the central aperture may receive a shaft of a base of the arrowhead. The arrowhead blade retention device may be positioned such that the blade retainers align with the tips or bottom portions of the arrowhead blades. In some embodiments, a disclosed arrowhead blade retention device is positioned between two components of an arrow and held in place by pressure between the two components, for example, between two threaded components. As an example, an arrow may include an arrowhead base coupled to an arrow shaft by threading. A disclosed arrowhead blade retention device may be positioned between the arrowhead base and the arrow shaft and retained by threaded tension between the components. In this manner, the disclosed arrowhead blade retention device may be a type of washer that is shaped to retain the arrowhead blades.

Disclosed arrowhead blade retention devices may be configured to deploy or release the arrowhead blades upon impact with a target. For example, a disclosed arrowhead blade retention device may include points of weakness or breaking points that break upon impact with a target. For example, the portion of wall between a blade retainer and an outer edge of the arrowhead blade retention device may be a point of weakness that breaks upon impact. The arrowhead blades may extend outwards upon impact with the target and the outward force of the blades on the walls surrounding the blade retainers may cause the arrowhead blade retention device to break and release the blades.

Turning to the figures, arrowhead blade retention device embodiments of the present disclosure will now be discussed in more detail.is a top isometric view of an arrowhead blade retention deviceof the present disclosure.is a top plan view of the arrowhead blade retention deviceof.is a bottom plan view of the arrowhead blade retention deviceof.is a front elevation view of the arrowhead blade retention deviceof.is a right side view of the arrowhead blade retention deviceof.is a rear isometric view of the arrowhead blade retention deviceof. As shown, the arrowhead blade retention devicemay include a body. The bodymay include a top wall, a bottom wall, and a sidewall or outer wall. The sidewallmay extend around the outer edge of the bodyand may include a front surface, a rear surface, a left side surface, and a right side surface. The left side surface is not shown in the drawings, as it is a mirror image of the right side surface.

The bodymay include a central bodyand a plurality of ears. The central bodymay be formed by a flat portion of the top wall. The central bodymay have a thickness T formed between the flat portion of the top walland the bottom wall. The thickness T may be sized to allow for flexibility of the body. For example, the thickness T may be within the range 0.010-0.150 inches, for example 0.020 inches. The central bodymay define a central aperture. As depicted, the central aperturehas a circular shape; however, other shapes are contemplated. The central apertureis sized to fit with an arrowhead or broadhead, such as the arrowhead or broadhead described in the '312 Patent. For example, the central apertureis sized to fit with a shaft of a base of the arrowhead, such as the base shaftdescribed below with respect to. The central aperturemay be sized to prevent a tight tolerance with the arrowhead, facilitating coupling of the arrowhead blade retention devicewith the arrowhead and alignment of the arrowhead blade retention devicewith the arrowhead blades.

The plurality of earsmay be formed by a curvature and extension of the top wallupwards from the central bodyor in a direction that is away from the bottom wall. The earsmay extend upwards at an angle from the central body. As an example, the earsmay extend at a 45 degree angle from the central body, though other angles are contemplated. In the depicted embodiment, the arrowhead blade retention deviceincludes two ears, a left earand a right ear; however, more or less than two earsare contemplated. For example, the number of ears may match the number of blades on an arrowhead or broadhead. For example, one, three, four, or more ears are contemplated. The earsmay be evenly spaced apart. The left and right earsare positioned on opposing sides of the central aperture. The left and right earsmay include left and right curved ear surfacesand left and right flat ear surfaces, respectively. It is contemplated that the left and right flat ear surfacesmay also be curved.

The left and right earsmay include a plurality of left and right blade retainers. In the depicted embodiment, the left and right blade retainersare recesses defined within the top wallon opposing sides of the central aperture. It is contemplated that the blade retainersmay be apertures, grooves, slots, slits, or the like. The left and right blade retainersmay be equal distanced from the central aperture. The left and right blade retainersmay be defined at least partially within the left and right curved surfaces, respectively. The left and right blade retainersmay include left and right recessed surfacesthat are recessed from the top wall. The left and right blade retainersmay include left and right retainer outer walls, also referred to herein as left and right recess outer walls. In embodiments where the left and right blade retainersare apertures, the left and right recessed surfacesare omitted. It is contemplated that the earsmay be omitted and the blade retainers may be formed in the top wall. The left and right blade retainersmay each have a diameter between about 0.050 inches to about 0.1 inches. For example, the retainer diameter may be 0.070 inches, 0.071 inches, 0.072 inches, 0.073 inches, 0.074 inches, 0.075 inches, 0.076 inches, 0.077 inches, 0.078 inches, or the like. Other sizing of the left and right blade retainersis contemplated to accommodate different sized or shaped arrowheads or broadheads.

Left and right lateral walls,may be formed between the left and right retainer outer walls(or left and right recess outer walls) and the sidewall, respectively. The left and right lateral walls,may have a thickness t. The thickness t may be sized to create a point of weakness or breaking point upon impact with a sharp edge. The thickness t may be thick enough to prevent breakage of the lateral walls,during flight, but thin enough to allow for breakage of the lateral walls,upon impact of the arrowhead with a target. The thickness t may depend on the types of blades being retained, including the blade size, thickness, and sharpness. In exemplary embodiments, the thickness t is between 0.010-0.90 inches, for example, 0.018, 0.019, 0.020, 0.021, or the like, inches.

The bodymay be shaped to reduce its aerodynamic signature on the arrowhead. As shown, the bodyhas an eye-shape or parallelogram shape with curved corners; however, other shapes are contemplated, including, for example, an oval or circular shaped body. In embodiments where the bodyis circular, the ears may be formed by raised opposing sides of the bodyor the ears may be omitted, as described with respect to the embodiment depicted in.

The bodymay be a flexible body configured to flex when external pressure or force is applied to the body. The flexible body may flex with flexion of an arrowhead coupled thereto. For example, the flexible body may flex with the arrowhead shaft as it moves or flexes during flight, acting as a shock absorber. The flexibility of the bodymay mitigate impact of the arrowhead blade retention deviceon the kinetic energy or inertia of the arrowhead during flight. The flexibility of the bodymay also prevent breakage of the bodyprior to impact with a target, as the bodymay flex relative to the arrowhead blades. The bodymay be made of a flexible and/or resilient material, including, for example, plastic, nylon, carbon fiber, non-ferrous metals, wood composite, fiberglass composites, molded epoxies, and other composite compositions. As an example, the bodymay include a plastic composition including nylon, such as, for example, polyamides such as Nylon 12 (PA12) or Nylon 6 (PA6). The bodymay include various other injectable plastic compounds such as high-density polyethylene (HDPE), polypropylene (PP), polyethylene terephthalate (PET), low density polyethylene (LDPE), and the like. The material of the bodymay be breakable when an external cutting force is applied to the material.

The arrowheadmay be the arrowhead shown and described in the '312 Patent. As shown, the arrowheadincludes a pointand a resilient shaft. In the depicted embodiment, the pointhas a three blade configuration, though other configurations are contemplated. The pointmay be coupled to the resilient shaftdirectly or through an intermediate component, such as the ferrule described in the '312 Patent. The resilient shaftand/or the ferrule may include threading to couple with threading on a threaded socket coupled to the point. The resilient shaftmay be composed of carbon fiber or another equally resilient material. The resilient shaftmay be disposed through a blade carrierallowing the blade carrierto move up and down the resilient shaft. A plurality of cutting bladesmay be pivotally mounted to the blade carrier. In the depicted embodiment, two cutting bladesare coupled to the blade carrier; however, more or less cutting bladesare contemplated, such as one, three, four, or more cutting blades. The cutting bladeseach have a blade tipat one end, a spine, and a cutting edge. The spineand the cutting edgeare on opposing sides of the cutting blade. The cutting edge, when deployed, is oriented toward the direction of flight of the arrowheadso that the cutting edgewill be deployed against the target material.

The resilient shaftmay be disposed within a base. The resilient shaftmay be coupled to the baseby threading or adhesive.show an exemplary base. The basemay include a base headand a base shaft. The base shaftmay include threadingalong at least a portion of the base shaft. The threadingmay couple with threading on an arrow shaft to couple the arrowheadto an arrow shaft. The base headmay include curved opposing edges, flat opposing edges, a top base head surface, and a bottom base head surface. The top base head surfacemay be a flat surface. The bottom base head surfacemay be a curved surface. The base headmay define a base central borethat receives the resilient shaft. The base headmay define a plurality of blade retention apertures. The blade retention aperturesmay be defined within the flat opposing edgesof the base head. The blade retention aperturesmay be positioned lateral to the base central bore. As shown, the blade retention aperturesare on opposing sides of the base central bore. In the depicted embodiment, the blade retention aperturesare slots; however, other shapes are contemplated that are sized to fit the cutting blades. The spinesof each of the cutting bladesmay be disposed within the blade retention apertures. The blade tipsof the cutting bladesmay extend through the blade retention aperturesand below the base head. The blade tipsof the cutting bladesmay extend through the blade retention aperturesa distance D below the bottom base head surface.

As shown in the figures, the arrowhead blade retention devicemay couple to the baseof the arrowhead. The base shaftmay be disposed within the central apertureof the arrowhead blade retention device. The top wallof the arrowhead blade retention devicemay be biased against the bottom base head surface. The curvature of the top wallmay align with or correspond to the curvature of the bottom base head surfacein a manner that minimizes spacing or gaping therebetween. The blade retainersmay align at least partially with the blade retention aperturesand may be positioned such that the portions of the cutting bladesthat stick out below the baseare disposed within the blade retainers. The blade tipsmay rest or bias against the recessed surfaces. The contact of the blade tipswith the recessed surfacesmay mitigate or prevent movement or rattling of the cutting blades. In embodiments in which the blade retainersare apertures and the recessed surfacesare omitted, the blade tipsmay be disposed within the apertures or extend partially below the arrowhead blade retention device. The cutting edgemay rest or bias against the left and right retainer outer wallsor against the left and right lateral walls,.

As shown in, the arrowhead blade retention devicemay be disposed diagonally across the base. The width of the arrowhead blade retention devicefrom left side surface to right side surfacemay be no greater than the diameter of the blade carrier. In the depicted embodiment, the width of the arrowhead blade retention deviceis the same dimensions as the diameter of the blade carrier. In other words, the sidewallof arrowhead blade retention devicedoes not extend out beyond the edges of the blade carrier, mitigating or eliminating impact of the arrowhead blade retention deviceon aerodynamics, wind resistance, and kinetic energy of the arrowheadwhile in flight.

is a front elevation view of the arrowheadofwith the cutting bladesin a deployed position. When target material is encountered, rearward force may be applied to the blade carrier, moving the blade carrieralong the resilient shafttowards the base. Such movement of the blade carriermay move the cutting bladesin an outward direction away from the resilient shaftand base, placing pressure from the cutting edgesof the cutting bladeson the left and right lateral walls,. The pressure of the cutting edgeson the left and right lateral walls,may break the left and right lateral walls,, deploying the cutting blades. The breaking of the arrowhead blade retention devicethereby allows deployment of the cutting blades.

While the disclosed arrowhead blade retention deviceis depicted with ears that break upon impact, it is contemplated that the ears may remain intact. In some embodiments, the ears may instead be reconfigured upon impact to deploy the cutting blades. For example, the ears may stick out past the outer edge of the arrowhead (e.g., the outer edge of the blade carrier) and may act as a barbed edge or catch of the arrowhead, catching a portion of the target material upon impact and folding or extending in a rearward position towards the arrow shaft. The folding or extension of the ears may move the ears off of the cutting blades, allowing the cutting blades to deploy or release upon impact with the target material.

In some embodiments, the ears may remain intact for use with a practice arrowhead. For example, it is sometimes desirable for a bow and arrow user to test an arrow to see how it flies relative to a target. For example, the user may want to ensure the trajectory of the arrow hits a desired target. In these instances, it may be desirable for a disclosed arrowhead blade retention device to retain the cutting blades upon impact with a target so that the arrow is easier to pull out of the target and the cutting blades do not dull. For example, the lateral walls may retain their structure when the cutting force of the cutting blades is exerted on them. In these embodiments, the arrowhead blade retention device may be made of a sturdier, more rigid material, such as aluminum, for example.

The left side surface is not shown in the drawings, as it is a mirror image of the right side surface. The bodymay be shaped to reduce its aerodynamic signature on the arrowhead. As shown, the bodyhas a circular shape.

The bodymay include a central body. The central bodymay be formed by a flat portion of the top wall. The bodymay have a thickness T formed between the top walland the bottom wall. The thickness T may be sized to allow for flexibility of the body. For example, the thickness T may be within the range 0.010-0.150 inches, for example 0.020 inches. The central bodymay define a central aperture. As depicted, the central aperturehas a circular shape; however, other shapes are contemplated. The central apertureis sized to fit with an arrowhead or broadhead, such as the arrowhead or broadhead described in the '312 Patent. For example, the central apertureis sized to fit with a shaft of a base of the arrowhead, such as the base shaftdescribed below with respect toor the base shaftdescribed with respect to.

In this embodiment, the opposing left and right recessesare connected and formed as a single recess in the top wall. While the blade retainerdepicted surrounds the entire central body, it is contemplated that the blade retainermay surround a portion of the central body. As one example, the blade retainermay surround half of the central body, forming a semi-circumferential shape. It is contemplated that the blade retainermay be two separate blade retainers (e.g., recesses, grooves, apertures, or the like) defined in the top wallon opposing sides of the central aperture, similar to the left and right blade retainersdescribed with respect to the arrowhead blade retention deviceof. The blade retainermay include a recessed surfacethat is recessed from the top wall. The blade retainermay include opposing inner and outer retainer walls,, respectively. The opposing inner and outer retainer walls,may be opposing inner and outer recess walls.

A lateral wallmay be formed between the outer retainer walland the sidewall. The lateral wallmay have a thickness t. The thickness t may be sized to create a point of weakness or breaking point upon impact with a sharp edge. The thickness t may be thick enough to prevent breakage of the lateral wallduring flight, but thin enough to allow for breakage of the lateral wallupon impact of the arrowhead with a target. The thickness t may depend on the types of blades being retained, including the blade size, thickness, and sharpness. In exemplary embodiments, the thickness t is between 0.010-0.90 inches, for example, 0.018, 0.019, 0.020, 0.021, or the like, inches.
