Description

CROSS-REFERENCE TO RELATED APPLICATION

Pursuant to relevant portions of 35 U.S.C. §119 and 37 CFR §1.53, this application is a non-provisional of, and claims the benefit and priority of, U.S. Patent Application No. 62/270,325, filed on Dec. 21, 2015. The entire contents of this application is hereby incorporated by reference.

TECHNICAL FIELD

This application is directed generally to the field of archery and more specifically to a broadhead assembly which can be used as either a mechanical (expandable) broadhead assembly or a fixed blade broadhead assembly.

BACKGROUND

Bow hunting has become a very popular sport in North America and around the world. A typical broadhead assembly used by sportsmen includes a blade set and a blade holder, which retains and couples the blade set to an arrow shaft. The blades used in the blade set have two (2) or more razor sharp blade edges which extend outwardly to form a cutting edge to penetrate a target animal's hide, tissue, and bone. Upon impact, the outwardly extended blades act to provide an optimum trauma site and thus quickly bring down the target animal by causing substantial hemorrhaging and tissue damage when struck. Such a wound would also create a blood trail to aid the hunter in tracking the target animal after it has been struck.
Generally, two basic types of broadhead assemblies are known in the art: mechanical (also commonly referred to as “expandable”) broadhead assemblies; and fixed blade broadhead assemblies. Mechanical broadhead assemblies retain the blade set close to the blade holder to maintain a low profile while in flight and then allow the blade set to open or expand outwardly upon impact. A fixed blade broadhead assembly retains the blade set in the same position while in flight and upon impact. Accordingly, the profile of the fixed blade broadhead assembly can be greater with a smaller impact wound to the target animal as compared to a mechanical broadhead assembly. However, while sacrificing some flight characteristics, fixed-blade broadhead assemblies may initially cut on impact in a more efficient manner than mechanical broadhead assemblies and may create a better wound channel for blood flow improving the likelihood of developing a good blood trail to track the target. On the other hand, mechanical broadhead assemblies may cause greater injury to the target's internal organs and thus bring down the target sooner.
Currently, bow hunters are forced to purchase separate blade sets and blade holders to use with each broadhead assembly which leads to added cost. This is also inconvenient for bow hunters as they are forced to carry multiple components with them while on the hunt, as well as spend extra time reconfiguring their arrow according to the target and hunting conditions. Moreover, broadhead assemblies need to meet certain weight thresholds in order to provide proper weight distribution and balance when installed on the arrow shaft. Abiding by these weight thresholds ensures optimal flight characteristics and performance of the arrow coupled to the broadhead assembly. Changing between a mechanical broadhead assembly and a fixed blade broadhead assembly on the same arrow shaft can affect weight distribution, thereby resulting in erratic flight and unpredictable performance.
The foregoing background describes some, but not necessarily all, of the problems, disadvantages and shortcomings related to the use of current mechanical and fixed blade broadhead assemblies.

DETAILED DESCRIPTION

The following description relates to a broadhead assembly in accordance with certain embodiments that is adjustable between fixed and expandable modes. It will be readily apparent that other variations and modifications are possible. In addition, certain terms are used throughout to provide a frame of reference in regard to the accompanying drawings. These terms, which may include “distal”, “proximal”, “inner”, “outer”, “internal”, “external” and the like are not intended to be limiting, unless so specifically indicated.
The herein described broadhead assembly can function as either a fixed blade broadhead assembly or a mechanical (“expandable”) broadhead assembly at the election of the bow hunter. This functionality can be accomplished by removable blades that are fixed in a retracted or partially retracted position while in flight, but can be expanded or kept in the fixed position upon impact with the target. The dual function of the herein described broadhead assembly can be accomplished by a selectable mechanism that in a first mode, retains the blades in their fixed retracted positions upon penetration of the target and in a second mode, enables the blades to expand when the broadhead assembly impacts the target.
Referring to FIGS. 1-4, the dual function broadhead assembly, (also herein referred to synonymously as an arrowhead assembly, or broadhead assembly) 100 generally includes a blade holder or body 110, a blade set 130, a collar 150, and a cap or tip 170. Each of the foregoing components will be described in greater detail.
As shown in FIGS. 3 and 4, the body 110 is substantially tubular having an axis X extending between a first or distal end 112 and an opposing second or proximal end 114. As shown and according to this embodiment, the body 110 is a single, unitary component that can be made from any suitable material such as, but not limited to, stainless steel, carbon steel, aluminum, metals, ceramics and alloys.
As shown, the body 110 has a substantially circular cross section and may be fitted with any number of blades 132 from the blade set 130. In another embodiment, the cross section of the body 110 may be polygonal, depending on the number of blades 132 used. For example, the body 110 can be defined by a triangular cross section if three (3) blades 132 are used, a square cross section if four (4) blades 132 are used, and so forth. In these alternate embodiments, each side of the body 110 is coupled to one blade 132 and has one axial slot or axial groove 119 that extends along a portion of the length of the body 110 and more specifically a blade coupling portion 116.
According to this embodiment and as shown in FIGS. 3 and 4, the first end 112 of the body 110 includes a tip coupling portion 113 having a narrowed outer diameter D1, FIG. 4, as compared to the remainder of the body 110. In an embodiment, the tip coupling portion 113 includes a plurality of external threads 117 that are configured to accommodate corresponding internal threads (not shown) of the tip 170 (FIG. 1). The use of threads, however, is optional. For example, the tip 170 can alternatively be snap-fitted to the tip coupling portion 113, or secured using other suitable means.
The body 110 further includes the blade coupling portion 116 and a neck 118. The blade coupling portion 116, which is formed on an intermediate part of the body 110 retains or couples the blade set 130 (FIG. 1) to the body 110 with the neck 118 extending between the blade coupling portion 116 and the first end 112. As shown in FIG. 3, the blade coupling portion 116 has an outer diameter D2 that is larger than D1 and the outer diameter of the neck 118, depicted as D3. The blade coupling portion 116 further includes one or more sockets or access holes 115 that can accept one or more fastening members (not shown). The fastening members can include pins, screws, cams, or any other suitable fastening member to removably couple each blade 132 of the blade set 130 to the body 110. The sockets 115 are dimensioned and sized in order to receive an Allen wrench or other suitable tool to aid in the removal and installation of the blade set 130 and the fastening member(s) to enable selective replacement of a blade 132 or entire blade set 130.
As noted, the neck 118 is positioned between the tip coupling portion 113 and the blade coupling portion 116. The outer diameter of the neck D3 is less than the outer diameter of the blade coupling portion D2, but greater than the diameter of the tip coupling portion D1. The body 110 further including an annular shoulder 124 at the distal most end of the neck 118. The neck 118 also includes two or more axial channels, slots, or axial grooves 119 that according to this embodiment, further extend into at least an axial portion of the blade coupling portion 116.
The second end 114 of the body 110 has an arrow coupling portion 120 defined by a maximum outer diameter D4 that is smaller than the diameter of the arrow shaft (not shown). As shown in FIGS. 1-2 and according to this depicted embodiment, the arrow coupling portion 120 includes a plurality of external threads 121 that are configured to engage a complimentary set of internal threads (not shown) in an arrow shaft (not shown) to couple the body 110 to the arrow shaft. However, the use of threads as a coupling means is optional, wherein the arrow coupling portion 120 may use any other suitable technique to mechanically and fixedly couple the body 110 to the arrow shaft (not shown). According to this embodiment, the body 110 and more specifically the proximal end of the blade coupling portion 116 is defined by an outer diameter as well as a proximally defined annular shoulder 122 configured and sized to limit the axial insertion of the body 110 into the arrow shaft (not shown), however in an alternate embodiment, the position of the defined shoulder 122 can be longitudinally adjusted by means known in the art and can also be used to fit the body 110 onto differently sized arrow shafts.
Referring to FIGS. 5-6, the blade set 130 includes two (2) or more blades 132 made from a suitable material such as, but not limited to stainless steel, carbon steel, metals, ceramics, alloys, or any other suitable rigid material that can maintain a sharp edge. The (2) or more blades are defined by a unitary and elongate blade body 133 having a leading end 134 and an opposing trailing end 136. For clarity, a single blade 132 is shown in FIG. 5, while a set of three (3) blades is shown in an assembled form in FIG. 6. As shown according to the depicted embodiment in FIG. 6, the body 110 is defined by three (3) slots or grooves 119 and three (3) blades 132. Each blade 132 is located diametrically at 120 degrees around the exterior of the body 110, as depicted FIG. 6.
With particular reference to FIG. 5, the trailing end 136 of each blade 132 defines a mounting point 139 for coupling with the blade coupling portion 116 (FIG. 1) of the body 110 (FIG. 1). More specifically, the mounting point 139 includes an opening that is sized to receive a fastening member (not shown) for assembly through the socket 115 (FIG. 1). The leading end 134 of each blade 132 includes at least one blade edge 131 a. In addition, each blade 132 further includes an extension arm 138 projecting transversely relative to the respective ends 134, 136. According to this embodiment, the extension arm 138 is fully exposed in the retracted position as shown in FIG. 2. The extension arm 138 includes at least one blade edge 131 b that is spaced from the blade edge 131 a, but is substantially coplanar therewith. The blade edge 135 is oppositely disposed relative to the extension arm 138 and extends over substantially the entire length between the leading end 134 and the trailing end 136 of the blade body 133. As shown, each of the blade edges 131 a, 131 b are formed at about a 45 degree angle relative to a longitudinal axis Y of the blade body 133. This angularity can be varied. For example, the blade edges 131 a, 131 b may be formed at angles between 30 and 50 degrees relative to the longitudinal axis Y of the blade body 133. As shown in FIG. 1 and in a retracted position, the blade edges 131 a, 131 b face the first end 112 of the body 110. As shown in FIG. 1, the blade edge 135 (FIG. 6) is positioned in the axial groove 119 of the body 110 when the broadhead assembly 100 is in the retracted position. The axial groove 119 acts to provide lateral stability to the blade 132 when the broadhead assembly 100, as coupled to an arrow shaft (not shown) is in flight.
According to this embodiment, the cutting surfaces of blade edges 131 a, 131 b, 135 have been ground on both sides of the blade 132 for sharpness and are geometrically designed to expand into deployment when the impact force is applied to extension arms 138 in the mechanical or blade expanding mode as shown in FIG. 2.
As shown in FIG. 6, three (3) identical blades 132 are illustrated, however any reasonable number of two (2) or more blades 132 may be used, provided that they are uniformly distributed around or on the sides of the body 110 to maintain adequate balance. In an embodiment, the blades 132 may not necessarily be identical to one another.
Referring to FIG. 1, the collar or sleeve 150 is coupled to the first end 112 of the body 110. Various version of the collar 150, and more specifically collar 150 a (FIGS. 7-8) and 150 b (FIG. 9), are herein described in greater detail with reference to FIGS. 7-9. Each collar 150 a, 150 b commonly is defined by a cylinder section having a first portion 152 a, 152 b and an opposing second portion 154 a, 154 b. The first portion 152 a, 152 b has a distal facing surface 162 a, 162 b and the second portion 154 a, 154 b has a proximal facing surface 164 a, 164 b. Each collar 150 a, 150 b also has an exterior surface 156 a, 156 b and an interior surface 158 a, 158 b. The interior surface 158 a, 158 b defines an inner bore 160 a, 160 b extending through each end of the collar that accepts a portion of the tip coupling portion 113 of the body 110 when in the assembled position (FIG. 1). In the assembled position (FIG. 1), the forward facing surface 162 a, 162 b contacts a portion of the tip 170 and the rearward facing surface 164 a, 164 b contacts a portion of the forward facing surface 124 of the body 110. Referring specifically to the embodiment of FIG. 8, the first portion 152 a of the collar 150 a has a diameter D5 and the second end is defined by diameters D6 and D7. As shown, D5 and D6 are equal to each other and D7 is greater than either D5, or D6. In another embodiment, D5 and D6 are not equal. Since D7 is larger than D5 and D6, the thickness T1 of the second portion 152 a of the collar 150 a at D7 is less than the thickness T2 of the collar at D5 or D6. In another embodiment, the inner bore 160 a has the same diameter extending from the first portion 152 a to the second portion 154 a of the collar 150 a and at least the second portion 154 a is made from a fracturable material.
As shown in FIGS. 7-9, the exterior surface 156 a, 156 b the collar 150 a, 150 b is smooth, however in another embodiment, the exterior surface 156 a, 156 b may have one or more surface features for the purposes of gripping, branding, aerodynamics, performance, or any combination thereof. As shown, the interior surface 158 a, 158 b is smooth, however in another embodiment, at least a portion of the interior surface 158 a, 158 b can have a plurality of threads or other features to assist in coupling the collar 150 a, 150 b to the body 110, the tip 170, or both.
Referring to the embodiment of FIGS. 7-8, the collar 150 a is formed from a suitable fracturable material such as a thin section of aluminum, a polymer or copolymer such as polyacetal copolymer, or any other suitable fracturable material. A suitable fracturable material has properties that will allow the collar 150 a to remain rigid with normal storage and handling. However, this collar 150 a is configured to be fractured or structurally compromised upon impact with the target, wherein the hinged extension arms 138 of the blades act against the integrity of the collar 150 a and cause the blades 132 to be released or deployed to the position shown in FIG. 2. As shown, the collar 150 a has inner bore 160 a defined by a plurality of arcuately-shaped radial portions 166 disposed circumferentially around the interior surface 158 a. In another embodiment, the interior surface 158 a of the collar 150 a includes features which cause the radial thickness of the collar to vary around the circumference of the inner bore 160 a.
Conversely and referring to the embodiment of FIG. 9, the collar 150 b can alternatively be formed from a rigid, non-fracturable or fracture resistant material such as steel, carbon steel, a thick piece of aluminum, or any other material that will secure the blade set 130 in the retracted position (FIG. 1) both while the broadhead assembly 100 is in flight and after impact with the target.
The tip 170, as shown in FIG. 10, may have a number of tip blades 172 extending from the apex 171 to the base 173 of the tip 170. In an embodiment, the number of tip blades 172 correspond to the number of blades 132 in the blade set 130 and is removable to allow the user to customize the arrowhead assembly 100 for a selected use or weight threshold. The tip 170 can include an interior threaded surface or any suitable means to retain the tip 170 on the body 110 and maintain its preferred alignment and balance including a locking pin (not shown). The tip 170 can be formed from stainless steel, titanium or any other known material having sufficient strength characteristics to obtain efficient penetration into the target while also creating a sufficient front-end load that enables broadhead deployment.
Referring to FIG. 1, the leading ends 134 of the blades 132 extend partially under the collar or sleeve 150 when in the retracted position. This allows the collar 150 to overlay a portion of the leading ends 134 and hold the blades 132 in their closed or retracted positions. Upon coupling the tip 170 to the broadhead assembly 100, the collar 150 is axially compressed or preloaded between the base 173 of the tip 170 and the forward facing surface or shoulder 124 of the body 110.
When the broadhead assembly 100 is to be used as a mechanical (expandable) broadhead assembly, the blades 132 are coupled to the blade coupling portion 116 of the body 110 with fasteners (not shown). Fasteners (not shown) are inserted through the mounting points 139 of the blades 132 into the aligned sockets 115 of the body 110 to couple the blades 132 and provide a pivot point for the blades 132 at their trailing ends 136. An embodiment of the fracturable collar 150 a (FIGS. 7-8) is inserted over the tip coupling portion 113 such that at least a portion of the tip coupling portion 113 is housed within the inner bore 160 a of the collar 150 a. The collar 150 a is positioned between the base 173 of the tip 170 and the shoulder 124 to retain a portion of the leading end 134 of the blades 132 under the collar 150 a in the retracted position (150 of FIG. 1) while the broadhead assembly 100 is in flight. In this embodiment, the retained portion of the leading end 134 of the blade 132 is positioned within one of the plurality of arcuately-shaped radial portions 166 of the interior surface 158 a of the collar 150 a. In the retracted position (FIG. 1), the blade edges 131 a, 131 b are exposed and forward facing while the blade edges 135 are positioned at least partially within the axial grooves 119. The axial grooves 119 are cut at a slight angle relative to the longitudinal axis Y of the blade body 133 to stabilize the blades 132 while in flight. Upon impact with the target, the axial force causes the leading ends 134 of the blades 132 to intentionally break through or fracture at least a portion of the collar 150 a.
As shown in FIG. 7, the second end 152 a of the collar 150 a will fracture at approximately T1 upon impact with the target and allow the blades 132 to expand or open (FIG. 2). Once the leading ends 134 of the blades 132 are no longer restrained by the collar 150 a, the blades 132 are caused to pivot about the fastener (not shown) to open radially outward and expose and position blade edges 135 so they face towards the tip 170 (FIG. 2) and are ready to penetrate the target upon impact. As a result, blade edges 131 a and 131 b are rotated clockwise such that the blade edges 131 a, 131 b face away from the body and are oriented at about a 45 degree angle relative to the longitudinal axis Y of the blade body 133. As shown in FIGS. 7-8, the collar 150 a can be reused more than once with the current blade set 130 by rotating the collar 150 a so that the fractured portions are positioned between the blades 132.
When the broadhead assembly 100 is to be used as a fixed blade broadhead assembly, the blades 132 are coupled to the blade coupling portion 116 of the body 110 with fasteners (not shown). The fasteners (not shown) are inserted through the mounting points 139 of the blades 132 into the sockets 115 of the body to couple the blades 132 and provide a pivot point for the blades 132 at their trailing ends 136. An embodiment of the non-fracturable collar 150 b (FIG. 9) is inserted over the tip coupling portion 113 such that at least a portion of the tip coupling portion 113 is housed within the inner bore 160 b of the collar 150 b. The collar 150 b is positioned between the base 173 of the tip 170 (FIGS. 1 and 10) and the shoulder 124 of the body 110 to retain a portion of the leading end 134 of the blades 132 under the collar 150 b in the retracted position (FIG. 1) while the broadhead assembly 100 is in flight. In the retracted position (FIG. 1), the blade edges 131 a, 131 b are exposed and forward facing while the blade edges 135 are positioned at least partially within the axial grooves 119. The grooves 119 are cut at a slight angle relative to the longitudinal axis of the body 110 to stabilize the blades 132 while in flight. Upon impact with the target, the axial force is transferred by the collar 150 b to the body 110 and into the arrow shaft (not shown). According to this embodiment, the rigidity of the collar 150 b keeps the blades 132 in the retracted position such that the blade edges 131 a, 131 b remain forward facing when the broadhead assembly 100 impacts the target. In this embodiment of the broadhead assembly 100, the grooves 119 retain the main blade edges 135 during flight and during impact of the broadhead assembly 100.
