The present invention is directed to an archery target with a covering layer that extends across at least the target face. The present archery target with a covering layer can be used as a freestanding target or as an insert for a three-dimensional archery target.
Various types of archery targets are known, including conventional three-dimensional life-size animal-simulating archery targets. Such targets have a shape resembling that of a game animal, for example, a deer or other animal. The targets may be formed in a single piece from a lightweight foam material, such as polyurethane foam. These targets are adapted for use with both broad head arrows, which comprise a plurality of intersecting razor blades tapering to a sharp point, and field point or target arrows. Critical target areas may be indicated on the target, e.g., by bull's eye markings, which are either applied onto or molded into the foam target.
Repeated arrow strikes on a foam archery target will cause the target to deteriorate. This outcome is especially true when broad head arrows are used. When a broad head arrow hits a target, the blades forming the arrowhead slice through the target material to a considerable depth. As the target material is hit repeatedly, pieces of the target are cut loose. Therefore, a target is destroyed much more rapidly with broad head arrows than with field point or target head arrows. However, even when field point or target head arrows exclusively are used, at least a portion of the target will inevitably be destroyed with repeated use.
In practice, a very large proportion of the arrow strikes on an archery target fall within a relatively small portion of the target. For example, archers will typically aim at an area of the target corresponding to vital organs of the animal which the target represents. Most archers will hit this target or bull's eye area most of the time. Therefore, this target area will be destroyed rapidly, due to repeated arrow strikes, while most of the remaining target remains relatively undamaged. The functional life of a three-dimensional life-size animal simulating archery target may be extended, and the cost of using such a target reduced, by making replaceable a target section of the archery target which is likely to be destroyed rapidly due to repeated arrow strikes.
Instead of forming the target from a single piece of molded foam, a three-dimensional life-size animal simulating archery target may be molded in multiple pieces, which are detachably joined together to form the target, such as disclosed in U.S. Pat. No. 4,477,082 (McKenzie, et al.). As one piece of the target is destroyed by repeated arrow strikes, this section alone may be replaced, eliminating the need to replace the entire target. Thus, the life of the target is extended, and the operating cost thereof reduced. The replaceable target section in McKenzie is approximately one-third of the total target. Thus, it is relatively expensive to replace. Further, the vertical dovetails holding the body sections together tend to come apart with repeated arrow strikes, due to the dynamic force of arrows impacting the target.
Another known three-dimensional life-size animal-simulating archery target is described in U.S. Pat. No. 5,503,403 (Morrell). This archery target includes a foam body, which may be formed of front and rear body sections connected together by a dovetail joint structure. The foam body includes a target insert receiving recess into which a target insert is placed. The target insert may be filled with packing material, such as cotton molt, for use with only target arrows, or may be formed of foam, for use with both broad head and target arrows. The target insert may be held in place in the recess using straps and wire. A body cover, which may be made of cloth, or molded in foam, is used to cover the removable and replaceable target insert.
U.S. Pat. No. 6,254,100 (Rinehart) discloses an archery target having a target section aperture formed therein and a replaceable target section adapted to fit in the target section aperture. The replaceable target section is held in place in the target section aperture by one or more support rods extending through support rod apertures formed in the body section and the replaceable target section. The support rods may also extend into other target body sections, to hold the target body sections together to form a structurally stable archery target. A replaceable target insert may be positioned in a target insert aperture formed in the replaceable target section. Arrowheads can be damaged or destroyed if they strike the metal support rods. Broad heads either become trapped in the target insert or will cause tear out with relatively few shots.
The present invention relates to an archery target with a covering layer on one or more of the target faces. One or more target elements are arranged in at least one stack. The target elements comprise side edges oriented toward a target face. A polymeric covering layer extends across the side edges to comprise the target face. The covering layer helps retain the target elements in the stacked configuration and provides a surface for applying target indicia.
The archery target can have a plurality of target faces. In one embodiment, the covering layer substantially surrounds the stack of target elements. In one embodiment, the polymeric covering layer substantially surrounds the side edges of the target elements to form a plurality of target faces. The polymeric covering layer can optionally provide a compressive force on the target elements.
The covering layer can have a generally uniform or a variable thickness relative to the side edges of the target elements along the target face. In one embodiment, the covering layer comprises a first thickness relative to the side edges of the target elements along a first target face and a second thickness along a second target face. The side edges of the target elements adjacent to the target face can have a generally planar or a curvilinear configuration.
In one embodiment, the target elements comprise two discrete stacks of target elements substantially surrounded by the covering layer. The discrete stacks of target elements preferably comprise one or more different materials and different shapes. In one embodiment, the first discrete stack of target elements is adjacent to a first target face and the second discrete stack of target elements is adjacent to a second target face.
The target elements optionally comprise a plurality of generally planar foam target elements. The target elements can optionally have reduced profile edges. The target elements can be a foam material having a density selected in the range of about 2 pounds per square foot to about 10 pounds per square foot.
The covering layer is preferably a compliant, deformable and resilient polymeric material. In one embodiment, the covering layer is a foam material. The covering layer can optionally include a reinforcing structure. The covering layer preferably has a thickness of at least 0.25 inches, and more preferably at least one inch. The covering layer is preferably compatible with the material of the target elements. In one embodiment, the covering layer is a self-healing material. In another embodiment, the covering layer is a homogeneous material. The covering layer can be a molded, encapsulating layer, a liquid coating applied to the stack of target elements, or a sheet material bonded to the stack of target elements. The covering layer can be one of a foam, a film, a non-woven web, a liquid coating, or a combination thereof. Straps can optionally be used to compress the target elements.
In one embodiment, the archery target can be a free standing archery target. In another embodiment, the archery target is part of an archery system, such as an insert for a three-dimensional archery target. The three-dimensional archery target typically includes a chamber with first and second generally opposing surfaces adapted to apply a compressive force to the target elements. The compressive force is optionally applied to the target elements by a cover attached to a body segment of the three-dimensional archery target. In another embodiment, one or more displacement mechanisms apply a compressive force to the archery target. The chamber preferably includes at least one surface adapted to mechanically couple with the archery target. The three-dimensional archery target typically simulates an animal.
The present invention is also directed to a method of making an archery target. The method includes arranging one or more target elements in a generally stacked configuration. The target elements comprise a plurality of side edge oriented toward a target face. A polymeric covering layer is located across the side edges and comprises the target face.
The covering layer can be applied with a uniform or a variable thickness relative to the side edges of the target elements along the target face. The side edges of the target elements can be arranged adjacent to the target face in a generally planar or curvilinear configuration. The present method includes arranging two discrete stacks of target elements in the archery target. The discrete stacks of target elements can be one or more different materials or different shapes. Each stack is preferably positioned adjacent to a different target face.
The target elements can be a plurality of generally planar foam elements. The method includes optionally deforming the side edges of the target elements to create reduced profile side edges. The covering layer is preferably a foam material. The method includes locating a reinforcing structure in the covering layer.
The covering layer can be molded around the stack of target elements. In another embodiment, the covering layer is a liquid applied to the stack of target elements. The method also includes bonding a polymeric sheet material to the stack of planar target elements and sealing any seams on the sheet material. The archery target can optionally be subjected to heat and/or pressure in order to create or to increase the compressive force on the target elements.
a through 5f illustrate various chambers for retaining target elements in a three-dimensional archery target in accordance with the present invention.
An archery target in accordance with the present invention can be constructed from one or more body segments, depending on a variety of factors, such as cost, size of the animal being simulated, the posture of the animal, and a variety of other factors. In the embodiment illustrated in
The body segments 22, 24 can be constructed from a variety of natural and synthetic materials, such as wood, paperboard, polymeric materials, such as plastics, foams, non-woven materials, and the like. The body segments 22, 24 can be solid or hollow, depending upon the material from which they are constructed.
Polyurethane foam materials are preferred because of the low cost, ease of molding using conventional molding techniques, lightweight, and durability. Polyurethane foam is a semi-rigid material that can be deformed slightly, but retains that deformed shape instead of returning to its original shape. Polyurethane foam with a density of about 10 pounds per square foot to about 50 pounds per square foot is preferred. When a broad head arrow tip impacts polyurethane foam, the blades of the points enter the foam causing a x-shaped cut. The foam cuts cleanly rather than being deformed and does not close around so the arrow is generally easy to withdraw. Outer surface 26 of the body segments 22, 24 is preferably coated with a material to seal the foam against moisture, to protect it from UV degradation, and give the target a lifelike appearance.
A variety of reinforcing members 28, 30 are preferably molded into the body segments 22, 24. The reinforcing members 28, 30 can be a variety of materials, such as metal, plastic or composite materials. Metal tubing provides a high degree of rigidity, but can damage an arrow tip that strikes it. Plastic tubing is typically less rigid, but is not as likely to damage the arrow tip.
In one embodiment, the reinforcing members 28, 30 extend beyond the bottom of the body segment 22 to provide anchors 32. The anchors 32 can be driven into the ground or attached to a base in order to support the archery target 20. In an alternate embodiment, metal stakes or other supporting structures are inserted into the optionally hollow reinforcing members 28, 30 to support the archery target 20.
In the illustrated embodiment, the reinforcing member 30 extends all the way into a portion of the second body segment 24 so as to increase the strength at the junction 34. The material and configuration of the reinforcing members 28, 30 can vary with the size and shape of the present three-dimensional archery target and a variety of other factors.

In the illustrated embodiment, the chamber 60 is bounded on four sides. Lower surface 62 of cover 42 forms a top surface of the chamber 60. Lower surface 64 and side surfaces 66, 68 form the other three surfaces of the chamber 60. In the illustrated embodiment, the cover 42 applies a compressive force 102 to the major surfaces of the target elements 52. The compressive force 102 is opposed by the lower surface 64. The lower surface 64 can optionally include a camber or non-planar structure 70 which serves to increase or concentrate the compressive force 102 in the center of the target face 104.
As used herein, “mechanically coupled” refers to interengaging structures on target elements and an archery target that resist displacement of target elements relative to an archery target due to an arrow strikes or an arrow being removed. Mechanical coupling does not require a tight mechanical fit between the interengaging structures. A gap may exist between some of the surfaces of the interengaging structures, such as illustrated in
The method of the present invention includes positioning a plurality of the target elements 52 in the chamber 60. Side edges 90, 92 of the target elements 52 are accessible through first target aperture 94 and second target aperture 96, respectively. The cover 42 is then replaced so that cover anchor 44 is located in recess 98 and cover anchor 46 is located in recess 100. Pins 48, 50 are replaced in holes 48a, 50a, respectively, so that the cover 42 is securely attached to the first body segment 22. In one embodiment, a reinforcing member is molded into the cover 42 (see
In the illustrated embodiment, the cover 42 applies a compressive force 102 to the target elements 52. The compressive force 102 can be increased or decreased by increasing or decreasing the number of target element 52 located in the chamber 60. The compressive force 102, either alone or in combination with the mechanical coupling of the structures 72, 74 with recesses 80, 82 releasably retain the target elements 52 in the first body segment 22. The side edges 90, 92 of the target elements 52 form the target face 104 located generally where the vital organs of the animal simulated by the archery target 20 are located.
The replaceable target assembly 40 can be repaired by removing the compressive force 102 and replacing some or all of the target elements 52. In many situations, the replaceable target assembly 40 can be restored to essentially perfect condition by replacing less than all of the target elements 52. The ability to replace individual target elements 52 significantly reduces the cost of maintaining the archery target 20 in working condition.
The target elements 52 are preferably constructed from a foam material, such as disclosed in U.S. Pat. No. 5,865,440 (Pulkrabek), which is incorporated by reference. The foam is weather resistant and can be used either indoors or outdoors. In one embodiment, the foam is compressed to about 70% to about 20% of its uncompressed thickness. In another embodiment, the foam is compressed to about 50% to about 5% of their uncompressed thickness. For high density foam that is not easily compressed, a compressive force of about 5-pounds/square foot or greater is typically used. Other materials, such as corrugated cardboard, softwoods in either solid form or layered structures such as plywood, and materials made from natural or synthetic fibers can also be used for the target elements 52. In another embodiment, the target elements 52 are constructed from a woven or a non-woven polymeric material.
As used herein, “target element” refers to a material adapted to be located in a chamber of an archery target. The target element can be a sheet material with an edge that forms a portion of a target face. Each layer in the replaceable target assembly can be discrete target elements or a larger piece of sheet material folded in a serpentine manner to arrange multiple edges into a target face. The larger piece of sheet material can optionally be die cut to facilitate folding. In another embodiment, the plurality of planar target elements discussed above can be replaced by a single continuous structure or material that extends across a portion of the target aperture in the three-dimensional archery target 20. For example, the target element 52 can optionally be a single piece of foam that extends substantially across the apertures 94, 96. Although the embodiments illustrated in the Figures show the edges of the target elements co-planar, it is possible for the replaceable target assembly to have a non-planar target face.
In one embodiment, the target elements 52 are about ⅛ inch to about ¼-inch thick cross-linked foam. Cross-linked foam exhibits greater self-healing at each puncture hole and provides longer target life, especially when the target is used with arrows having broad head or expandable tips. The combination of relatively thin target elements 52 and the type of foam produce very little compression about the arrow shaft and head. The foam also prevents the arrow from turning during removal, which assures that broad heads follow the same hole on ingress and egress, without tearing. Arrows are therefore easily withdrawn without resort to arrow gripping devices or excessive arm, shoulder or tugging body movement.
The foam may be open or closed cell, although a closed cell polyethylene foam is preferred. Close celled foam is less susceptible to the intrusion of moisture and deterioration from ultraviolet rays. A variety of foam materials, such as polyethylene or polyurethane foams or blends thereof may also be used to advantage. The foam preferably has a density of about 2 pounds per square foot to about 10 pounds per square foot. In contrast to higher density foam materials, it is believed the low-density material facilitates arrow removal without the friction or adherence of the layered material to the arrow that is exhibited by higher density and continuous pour foam targets. The weight of the archery target 20 is also reduced when using a low density foam and which is advantageous for the archer who wants to transport a target to his or her hunting camp.
a is a top view of a three-dimensional archery target 110 having a chamber 112 with a single target aperture 114.
b is a top view of a three-dimensional archery target 120 with an alternate chamber 122 including curved structures 124, 126 adapted to mechanically couple with the target elements 132. The curved structures 124, 126 also serves to deflect arrows 130 towards the center of the chamber 122.
c is a top view of a three-dimensional archery target 140 having a chamber 142 with no structure for mechanically coupling with the target elements 148. Rather, the target elements 148 are retained in the chamber 142 by friction, such as along side edges 148a, 148b of the target element 148 and the side surfaces 144, 146 of the chamber 142. In another embodiment, frictional forces are applied to the target elements 148 by the lower surface of the cover and the lower surface of the chamber (see e.g.,
d is a top view of an archery target 150 in which the chamber 152 includes a pair of opposing concave recesses or undercuts 154, 158 adapted to mechanically couple with target elements 156. The undercuts 154, 158 extend into the body segment a sufficient amount to retain the target element 156 in the archery target 150. In an embodiment where the target element 148 is a single piece of material, the target element is preferably constructed from a resilient material, such as foam, that will return to substantially its original shape after being deformed to engaged with the undercuts 154, 158.
e is a top view of an archery target 160 having a chamber 162 with tapered sidewalls 164, 166. The tapered sidewalls serve to direct arrows towards the center of the chamber 162. The target elements 168 preferably have corresponding tapers to mechanically couple with the sidewalls 164, 166.
f is a top view of an archery target 170 having a chamber 172 with a pair of opposing tapered structures 174, 176. The tapered structures 174, 176 mechanically couple with corresponding tapers in the target elements to retain the target elements 178 in the chamber 172.
In one embodiment, plate 208 is located on top of the stack of target elements 210. The plate can be any rigid or semi-rigid material capable of transmitting a compressive force to the target elements 210, such as wood, plastic, metal or composites thereof. Wood and plastic are preferred because an arrow tip striking a metal plate would likely be damaged.
In one embodiment, displacement mechanisms 212 are provided to displace the plate 208 into a compressive relationship with the target elements 210. The illustrated displacement mechanisms 212 are threaded members embedded in the first body segment 22. As best illustrated in
In another embodiment, the displacement mechanisms 212 are an integral part of the plate 208. For example, the plate 208 could be two plates with a scissors mechanism or cam structure adapted to displace one plate relative to the other.
In another embodiment, the displacement mechanisms 212 are eliminated and the plate 208 is a wedge shaped member that is pushed into the chamber 202 through one of the target apertures 204, 206 after the target elements 210 are in place. The wedge shape of the plate 208 creates the compress force 216 on the target elements 210 located in the chamber 202. A pair of wedge shaped plates 208 simultaneously forced into both target apertures 204, 206 is preferred. The opposing forces applied to the opposing wedge shaped members serve to minimize movement or shifting of the target elements 210 in the chamber 202.
The wedge shaped plates 208 can be located on the top, the bottom, or anywhere in the stack of target elements 210. In one embodiment, the wedge shaped plate 208 is constructed from a high density foam that can be inserted anywhere in the stack of target elements 210. The compressive force 216 can be increased by increasing the number of wedge shaped plates 208 inserted into the stack of target elements 210 and/or by increasing the number of target elements 210 in the chamber 202.
In yet another embodiment, a replaceable target assembly, such as the replaceable target assembly 270 in
In another embodiment, the replaceable target assembly 270 is a continuous piece of homogeneous or composite material, such as foam, having the opposing recesses 280, 282, with or without the plates 276, 278. In yet another embodiment, the replaceable target assembly 270 is a plurality of pieces of material, such as foam, bonded together to form a single structure. Any of the target element shapes disclosed herein can be used in these various embodiments of the replaceable target assembly 270.
The replaceable target assembly 270 of
As best illustrated in
In the preferred embodiment, the covering layer 302 applies a compressive force 316 to the target elements 304. In an alternate embodiment, straps 364 or other mechanisms can be used to compress the target elements 304 prior to adding the covering layer 302 (see e.g.,
Planes containing the target elements 304 are preferably perpendicular to target faces 308, 310. Accordingly, the target elements 304 can be arranged vertically (see e.g.,
The covering layer 302 can have a uniform or variable thickness relative to the target elements 304. As illustrated in
The target elements 324, 326 can differ in composition, density, thickness, cross-sectional geometry, and the like. For example, the target elements 324 can have a density of about 2 pounds per square foot and the target elements can have a density of about 10 pounds per square foot. As a result, arrow penetration in the target face 327 can be engineered to differ from arrow penetration in the target face 328, such as to simulate different game animals. Additionally, the shape of the target faces 327, 328 can differ. In the illustrated embodiment, the target face 327 is generally planar, while the target face 328 is curvilinear. Due to the polymeric nature of the covering layer 322, the surfaces comprising the target faces 327, 328 can assume any shape and/or any texture. The target faces 327, 328 preferably have a shape corresponding to the desired game animal.
In one embodiment, reinforcing layer 348 is included in the covering layer 346. The reinforcing layer 348 can be attached to a surface of the covering layer 346 or molded into the material comprising the covering layer 346. Various reinforcing structures can optionally be included in the covering layer 346 such as fiberglass, woven and non-woven polymeric webs, and cellulose-based reinforcing webs. Example of such structures are disclosed in U.S. Pat. No. 5,055,242 (Vane); U.S. Pat. No. 5,910,458 (Beer); U.S. Pat. No. 5,286,553 (Haraguchi); U.S. Pat. No. 4,983,453 (Beall); and U.S. Pat. No. 6,080,482 (Martin).
In the illustrated embodiment, target elements 410 are exposed along top surface 412 of the replaceable target assembly 400. This feature permits a compressive force 414 to be applied to the target elements 410, such as in one of the three-dimensional archery targets disclosed herein. Alternatively, the covering layer 402 can apply the compressive force 414 to the target elements 410.
Leaving the top surface 466 exposed permits compressive force 468 to be applied to the target elements 454 during application of the covering layer 452. Once the covering layer 452 is applied, it provides compressive force 468 to the target elements 454. Because the covering layer 452 grips the target elements 454 along the edges, the target elements 454 may bulge slightly in the center of the top surface 466.
In an embodiment without straps or other mechanisms to apply the compressive force 468 to the target elements 454, all four sides 456, 458, 460, 462 can serve as target faces. The replaceable target assembly 450 is particularly well suited to operate as a free-standing archery target. Any of the modifications and variations discussed herein can be incorporated in the replaceable target assembly 450.
The covering layer 350 provides a flat and stable surface for applying indicia 366 to the replaceable target assembly 350. The indicia 366 can be for example concentric circle, an illustration of a game animal or portion thereof, an illustration of vital organs of a game animal, and the like. The indicia 366 can be applied using a variety of techniques, such as silk screening, printing, adhering a decal or applique, or a variety of other techniques known to those of skill in the art.
In an embodiment with optional straps 364, the sides 358 and 362 are typically the target faces. The replaceable target assembly 350 is particularly well suited to operate as a free-standing archery target. Any of the modifications and variations discussed herein can be incorporated in the replaceable target assembly 350.
As used herein, “covering layer” refers to a polymeric material extending substantially across at least one target face of a replaceable target element. The covering layer can optionally extend along other surfaces of the replaceable target element. In one embodiment, the covering layer extends substantially around the entire stack of target elements.
The covering layer is preferably compliant, deformable, resilient and at least partially self-healing. As used herein, “self-healing” refers to materials that when punctured or torn, tend to substantially reform or close after a short time. Materials possessing these characteristics are well suited to stand-up to repeated arrow strikes without substantial deterioration. The covering layer can be constructed from a thermoplastic or a thermoset material and may be porous or non-porous.
In one embodiment, the polymeric material is homogeneous. Various additives, fillers, colorants, and the like can also be added to the polymeric material.
The covering layer preferably bonds to the side edges of the target elements. In some embodiments, the covering layer will also bond to planar surfaces of the target elements. Bonding is enhanced by selecting a material for the covering layer that is compatible with target elements. As used herein, the phrase “compatible” in the context of a polymeric material refers to one selected or treated so as to facilitate penetration and/or essentially complete wetting of the surfaces of the target elements, provide desired physical properties of the cured or finished assembly, such a compliance, deformability, resilience and at least some self-healing properties, and is chemically stable when exposed to environmental conditions.
The covering layer of the present invention is preferably constructed from a polymeric material, such as for example polyethylene foam or polyurethane foam. The covering layer preferably has a thickness of at least 0.25 inches, more preferably at least 1.0 inch, and most preferably at least 2.0 inches. As discussed above, the thickness of the covering layer relative to the side edges of the target elements can vary along a single target face or between target faces.
The covering layer can optionally be molded to the stack of target elements. In one embodiment, the covering layer only extends along one or more target faces. In another embodiment, the covering layer substantially encapsulates the entire stack of target elements.
The polymeric material is optionally injected into a mold containing the stack of target elements under pressure so as to apply a compressive force to the target elements. The cured polymeric material acts as a tension member maintaining a compressive force on the target elements. In another embodiment, straps or other mechanical devices are used to compress the target elements before the polymeric material is introduced into the mold. In yet another embodiment, a compressive force is applied to the stack of target elements during injection of the polymeric material. Once the polymeric material is partially cured, the covering layer grips the edges of the target elements and maintains a compressive force.
In another embodiment, the covering layer is sprayed onto some or all of the surfaces of the stack of target elements. In some embodiments, shrinkage of the polymeric material during curing provides a sufficient compressive force on the target elements. In another embodiment, the polymeric material is subject to further processing after being applied to the stack of target elements, such as for example the application of heat and/or pressure. For example, in embodiments where the covering layer is constructed from a thermoplastic, the entire replaceable target element can be simultaneously compressed and heated. Once the covering layer cools, it will retain at least a portion of its compressed configuration, and hence, compress the target elements.
In yet another embodiment, the covering layer is one or more polymeric sheets bonded or laminated to at least the side edges of the target elements. The polymeric sheets can be bonded or laminated to one or both of the planar surfaces of the target elements as well. The polymeric sheets can be bonded or laminated using a variety of techniques, such as for example thermal bonding, adhesive bonding, ultrasonic bonding, solvent bonding, and the like. The polymeric sheets can optionally be self-supporting foam panels, films, non-woven webs, and the like. The seams between adjacent portions of the polymeric sheet materials are preferably sealed during the bonding process.
All patents and patent applications disclosed herein, including those disclosed in the background of the invention, are hereby incorporated by reference. Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention. In addition, the invention is not to be taken as limited to all of the details thereof as modifications and variations thereof may be made without departing from the spirit or scope of the invention. For example and although the target elements of uniformly thick layers is disclosed, differing thickness might also be incorporated into the target assembly.
