The present description relates generally to an archery target configured to receive a pointed projectile, such as an arrow. More particularly, the present description relates to an archery target having a coated liner which enables detailed printing and extends the target's useful life.
Archery targets exist in a variety of different forms. Generally, archery targets include marking (e.g., a bull's eye, a ring, etc.) indicating a target area which an archer attempts to strike with an arrow. Some archery targets are simple paper targets on which the target marking is printed, drawn, or otherwise provided Such paper targets are typically attached to a foam block or other material capable of stopping an incoming projectile and are usually discarded after a single use.
Other archery targets are intended to be more durable and are capable of reuse. For example, compression bag targets feature a packed material inside a bag. Typically, the bag is formed from a woven polypropylene material and may include a target marking printed on a surface of the woven material. However, after repeated strikes from a pointed projectile, certain portions of such targets (e.g., the portions including the target marking) are likely to deteriorate, thereby requiring the targets to be replaced. For example, with respect to compression bag targets, the woven fibers often break when impacted by an arrow. Such breakage can result in large holes in the target after repeated arrow strikes.
Advances in materials science have produced materials capable of self-repair after being damaged (e.g., punctured by an arrow). Such “self healing” or “self sealing” materials can extend the life of a target by providing some degree of self-repair to counter the deterioration caused by repeated arrow strikes. However, it is difficult to effectively and permanently embed a target marking on such materials.
One implementation of the present disclosure is an archery target including an impact-absorbing core configured to arrest an incoming projectile and a multilayered bag enveloping the impact-absorbing core. The multilayered bag defines an outer surface of the target and includes a flexible fabric layer comprising a plurality of interwoven fibers and a polyurethane coating layer applied to the flexible fabric layer. The polyurethane coating at least partially overlaps the flexible fabric layer such that the polyurethane coating layer at least partially fills spaces between the plurality of interwoven fibers. In some embodiments, the plurality of interwoven fibers have a denier rating of at least one thousand. In some embodiments, the polyurethane coating layer has a thickness between two millimeters and four millimeters. In some embodiments, the polyurethane coating layer is applied to an inward-facing surface of the flexible fabric layer.
In some embodiments, the archery target further includes a marking defining a target area. The marking may be applied to the multilayered bag using a dye sublimation process. In some embodiments, the flexible fabric layer comprises a woven polyester fabric and the marking is sublimated to the woven polyester fabric. In some embodiments, the marking is applied to an outward-facing surface of the multilayered bag.
In some embodiments, the plurality of interwoven fibers are configured to reversibly displace in response to receiving an incoming projectile such that the incoming projectile penetrates the flexible fabric layer through a space between the plurality of interwoven fibers without breaking the fibers. In some embodiments, the polyurethane coating is configured to re-fill the space between the plurality of interwoven fibers in response to removing a captured projectile from the space.
In some embodiments, the archery target further includes a mechanism for repeatable opening and closing of the multilayered bag and for providing access to the impact-absorbing core. In some embodiments, the archery target further includes a handle extending from an upper portion of the multilayered bag. The handle may include a first end secured to the multilayer bag and a second end secured to the multilayer bag. In some embodiments, the handle includes a grip surrounding the handle between the first end and the second end.
Another implementation of the present disclosure is a multilayered archery target including a polyester fabric layer comprising a plurality of polyester fibers having a denier rating of at least one thousand, a polyurethane coating layer applied to the polyester fabric layer and at least partially overlapping the polyester fabric layer such that the polyurethane coating layer at least partially fills spaces between the plurality of polyester fibers, and a marking defining a target area. The marking may be applied to the multilayered archery target using a dye sublimation process. In some embodiments, the marking is sublimated to an outward-facing surface of the polyester fabric layer.
In some embodiments, the plurality of polyester fibers are configured to reversibly displace in response to receiving an incoming projectile such that the incoming projectile penetrates the polyester fabric layer through a space between the plurality of polyester fibers without breaking the fibers. In some embodiments, the polyurethane coating layer is applied to an inward-facing surface of the polyester fabric layer and fills the spaces between the plurality of polyester fibers such that an outward-facing surface of the polyester fabric layer is substantially smooth. In some embodiments, the multilayered archery target further includes one or more grommets defining holes extending through the multilayered archery target.
Another implementation of the present disclosure is a method for manufacturing a multilayered archery target including coating a first surface of a polyester fabric with a layer of polyurethane, applying a marking defining a target area to a second surface of the polyester fabric opposite the first surface using a dye sublimation process, forming the coated and marked polyester fabric into a multilayered bag, and inserting, into the multilayered bag, an impact-absorbing core configured to arrest an incoming projectile. In some embodiments, the polyester fabric comprises a plurality of polyester fibers having a denier rating of at least one thousand. In some embodiments, the method further includes attaching to the multilayered bag at least one of: a handle, a grommet, and a mechanism for repeatable opening and closing of the multilayered bag.
In some embodiments, coating the first surface of the polyester fabric with the layer of polyurethane includes at least partially filling spaces between the plurality of polyester fibers with the layer of polyurethane such that the layer of polyurethane at least partially overlaps the polyester fabric. In some embodiments, the layer of polyurethane has a thickness between two millimeters and four millimeters.
Those skilled in the art will appreciate that the foregoing summary is illustrative only and is not intended to be in any way limiting. Other aspects, inventive features, and advantages of the devices and/or processes described herein, as defined solely by the claims, will become apparent in the detailed description set forth herein and taken in conjunction with the accompanying drawings.
Referring generally to the FIGURES, an archery target and components thereof are shown according to various exemplary embodiments. The archery target is shown as a “bag target” including an impact-absorbing core and a multilayered outer surface (e.g., a bag) enveloping the impact-absorbing core. The impact-absorbing core may comprise any material capable of capturing and retaining an incoming projectile (e.g., an arrow). For example, the impact-absorbing core may include strips of polyester, polypropylene, Kevlar, ballistic nylon, foam beads, a foam block, or other suitable materials.
The multilayered bag provides a durable container for the impact-absorbing core and may be marked to present a target area (e.g., a bull's-eye, a circle, a ring, etc.). The multilayered bag includes a layer of flexible fabric (e.g., polyester fabric). The fabric layer includes a plurality of individual fibers which may be woven or non-woven. Advantageously, the plurality of fibers are configured to receive an incoming projectile without breaking, tearing, or otherwise permanently deforming. For example, in some embodiments, the plurality of fibers have a denier rating (e.g., a measurement of linear mass density) of at least one thousand. When an incoming projectile impacts the fabric layer, the nearby fibers may reversibly displace (e.g., bend, move, etc.) and allow penetration of the projectile through a space between the fibers without breaking the fibers. The high denier rating increases fiber strength reduces the potential for breakage caused by repeated arrow strikes.
Traditional bag targets have not used fabrics having a high denier rating due to the difficulty of embedding a target marking on such fabrics. Advantageously, the archery target described herein overcomes this difficulty by coating the fabric layer with a layer of polyurethane. The polyurethane coating may at least partially overlap with the fabric layer and at least partially fill the spaces between the high denier fibers. The resulting multilayered material is suitable for applying a target marking (e.g., using a dye sublimation process) while providing improved durability and resistance to fiber breakage. Furthermore, the polyurethane coating may re-fill the spaces between fibers in response to the removal of an arrow from such spaces, thereby providing a degree of self-healing for the multilayered bag material.
Before discussing further details of the archery target and/or the components thereof, it should be noted that references to “front,” “back,” “rear,” “upper,” “bottom,” “right,” and “left” in this description are merely used to identify the sides and/or surfaces of the archery target as they are oriented in the FIGURES. The terms “inward-facing” and “outward-facing” refer to directions toward and away from, respectively, the approximate center of the archery target and/or designated parts thereof. These terms are not meant to limit the element which they describe, as the various elements may be oriented differently in various applications. It should further be noted that for purposes of this description, the term “coupled” means the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or moveable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate members being attached to one another. Such joining may be permanent in nature or alternatively may be removable, releasable, or reversible in nature.

Impact-absorbing core 12 may be configured to minimize the force of impact experienced by the incoming projectile (e.g., by gradually arresting the projectile, by providing cushioning, etc.). In some embodiments, impact-absorbing core 12 is configured to reduce the friction generated upon impact, thereby reducing the potential for heat-related damage (e.g., melting, burning, warping, etc.) to both the incoming projectile and to archery target 10. Furthermore, the reduced friction may facilitate removal of captured arrows from archery target 10 without requiring any sort of lubricant or a removal device. Impact-absorbing core 12 may retain captured arrows in a rigid position or in a flexible position.
Outer bag 20 may completely envelop and/or contain impact-absorbing core 12 and provide an external housing for archery target 10. In some embodiments, outer bag 20 may be formed from a multilayered material 21. Thus, outer bag 20 may be referred to as a multilayered bag. Outer bag 20 is shown to include a plurality of markings 26 visible on an outward-facing surface thereof. Markings 26 may be target markings (e.g., bull's-eyes, circles, rings, etc.) indicating a target area at which an archer can take aim. Markings 26 may be applied to multilayered material 21 using a dye sublimation process or any other suitable marking technique.

Archery target 10 is shown to include a plurality of sides or faces that may define one or more target zones. Advantageously, providing a target with multiple sides and/or target zones may improve the versatility of archery target 10 by enabling the archer to take any of a number of positions relative to the target 10. For example, the archer can shoot target 10 from above, below, in front of, or behind the target. Further, providing a target with multiple sides and target zones may allow a single target to be used for different types of practice (e.g., arrow placement, honing, etc.).
In some embodiments, archery target 10 is a hexahedral (i.e., six-sided) object having a first face or front surface 31, a second face or rear surface 32, a third face or left side surface 33, a fourth face or right side surface 34, a fifth face or top surface 35 and a sixth face or bottom surface 36. Each of surfaces 31-36 may define one or more target zones or areas configured to receive a pointed projectile. In other embodiments, one or more of faces 31-36 (e.g., top surface 35, bottom surface 36, etc.) may not include a target zone. In addition to defining one or more target zones, surfaces 31-36 may be configured to rest upon the ground or another surface to support archery target 10 in a relatively stable position. Such a configuration allows an archer to selectively turn or otherwise reposition archery target 10 to reveal or conceal different target zones.

Fabric layer 22 may comprise a flexible (e.g., soft, non-rigid, etc.) fabric such as polyester, polypropylene, cotton, or other natural or synthetic fabric materials. Fabric layer 22 is shown to include a plurality of individual fibers 23. Fibers 23 may include multiple rows of substantially horizontal fibers and multiple columns of substantially vertical fibers. Fibers 23 may be woven (e.g., in an alternatively overlapping woven pattern) or non-woven (e.g., in an overlaid mesh). In an exemplary embodiment, fibers 23 are woven polyester fibers.
Advantageously, fibers 23 may be configured to receive an incoming projectile without breaking, tearing, or otherwise permanently deforming. In some embodiments, fibers 23 have a denier rating (e.g., a measurement of linear mass density) of at least 1000. This high denier rating may advantageously increase fiber strength and reduce the potential for fiber breakage caused by repeated arrow strikes. In some embodiments, fibers 23 may have a higher denier rating (e.g., of at least 1200, at least 1400, at least 1600, at least 1800, etc.) or a lower denier rating (e.g., at least 800, at least 600, at least 400, etc.). In a preferred embodiment, fibers 23 have a denier rating of approximately 1680. Traditional bag targets have not used fabrics having a denier rating in excess of 1000 due to the difficulty of embedding a target marking on such fabrics. Archery target 10 overcomes this difficulty by coating fabric layer 22 with a polyurethane layer 24.
Polyurethane layer 24 may comprise any type of polyurethane, resin, epoxy, or other similar coating. In some embodiments, polyurethane layer 24 includes a polymer composed of a chain of organic units joined by carbamate (e.g., urethane) links. Polyurethane layer 24 may include a thermosetting polymer (e.g., that does not melt when heated) or a thermoplastic polymer (e.g., that melts or softens when heated). Polyurethane layer 24 may be formed by reacting an isocyanate with a polyol. In some embodiments, both the isocyanates and polyols used to make polyurethane layer 24 may contain, on average, two or more functional groups per molecule. Polyurethane layer 24 may include any number or type of chain extenders, cross-linkers, catalysts, surfactants, and/or other molecular additives.
In some embodiments, polyurethane layer 24 may be applied to fabric layer 22 by spraying (e.g., as a fine mist) liquid polyurethane components (e.g., mixed or unmixed isocyanates, polyols, etc.) onto a surface of fabric layer 22. Polyurethane layer 24 may be applied to an inward-facing surface of fabric layer 22, an outward-facing surface of fabric layer 22, or both surfaces of fabric layer 22. In some embodiments, polyurethane layer 24 may have a thickness between two millimeters and four millimeters. In an exemplary embodiment, polyurethane layer 24 may have a thickness of approximately three millimeters.
In some embodiments (shown in
In some embodiments, polyurethane layer 24 provides additional advantages to multilayered material 21 and archery target 10. For example, polyurethane layer 24 may hold together fibers 23 to prevent gaps or holes from forming in multilayered material 21. Polyurethane layer 24 may provide water resistance or waterproofing to multilayered material 21. Furthermore, polyurethane layer 24 may re-fill spaces between fibers 23 in response to the removal of an arrow from such spaces, thereby providing a degree of self-healing for multilayered material 21.

Multilayered material 21 is shown to include a plurality of fibers 23 comprising fabric layer 22. Fibers 23 are shown to include multiple rows 25 of substantially horizontal fibers and multiple columns 27 of substantially vertical fibers. Fibers 23 are shown as woven fibers. However, in other embodiments, fibers 23 may be non-woven. For example, rows 25 may be overlaid onto columns 27 and united with columns 27 (e.g., bonded, held together, joined, etc.) by polyurethane layer 24.

As previously described, in some embodiments, multilayered material may be used without impact-absorbing core 12 and/or without forming multilayered material 21 into outer bag 20. For embodiments in which multilayered material 21 is used without impact-absorbing core 21, grommets 48 may be used to hang or otherwise secure multilayered material 21 to a projectile-arresting element (e.g., a foam block, a solid backing, a separate impact-absorbing material, etc.). In some embodiments, grommets 48 may be provided in one or more corners of archery target 10 (e.g., upper corners, lower corners, etc.). In other embodiments, a grommet 48 may be centered along a top edge of archery target 10 (e.g., in the case of a single grommet 48) or elsewhere located about archery target 10.

Advantageously, the high denier rating (e.g., of at least one thousand) may improve the strength of the polyester fibers and prevent the fibers from breaking when impacted by an arrow. The polyester fibers may reversibly displace in response to receiving an incoming projectile, thereby allowing the projectile to pass through a space between fibers without breaking, tearing, or otherwise damaging the fibers comprising the polyester fabric.
The polyurethane coating may be applied to one or both surfaces of the polyester fabric. In some embodiments, the polyurethane coating has a thickness between two millimeters and four millimeters. In an exemplary embodiment, the polyurethane coating has a thickness of approximately three millimeters. In some embodiments, the polyurethane coating may at least partially overlap with the polyester fabric such that the polyurethane coating at least partially fills spaces between the plurality of polyester fibers. The polyurethane coating may hold the fibers together, provide water resistance or waterproofing, provide elasticity to the plurality of fibers (e.g., such that the fibers return to their original positions after removal of a projectile), refill spaces between fibers upon the removal of an arrow, or provide other advantages for the multilayered material.
Process 200 is shown to further include applying a marking defining a target area to a second surface of the polyester fabric opposite the first surface using a dye sublimation process (step 204). In some embodiments, the marking is a target marking (e.g., a bull's-eye, circle, ring, etc.) indicating a target area at which an archer can take aim. In other embodiments, the marking may be a product logo, a decal, or other image applied to the polyester fabric. Advantageously, the polyurethane coating applied in step 202 may facilitate application of the marking by smoothing the second surface. This advantage allows a crisp and clear marking to be applied to the polyester fabric while maintaining the fiber strength and durability resulting from the use of a fabric with a high denier rating.
In some implementations, process 200 may be terminated after completing step 204. Terminating process 200 after completing step 204 results in the formation of multilayered material 21 as previously described. Multilayered material 21 may be used as a standalone target without forming material 21 into a bag or inserting an impact-absorbing core into the bag. In other implementations, process 200 may be continued to form the bag target shown in
Process 200 is shown to further include forming the coated and marked polyester fabric into a multilayered bag (step 206) and inserting, into the multilayered bag, an impact-absorbing core configured to arrest an incoming projectile (step 208). In some embodiments, forming the coated and marked polyester fabric into a bag may include folding a single sheet of multilayered material 21 into the shape of a bag. In other embodiments, multiple sheets of material 21 may be joined, united, or otherwise combined to form the multilayered bag.
In some embodiments, the impact-absorbing core may include strips of polyester fabric, polypropylene fabric, Kevlar, ballistic nylon, or other materials which are impermeable or substantially impermeable to an incoming projectile. In other embodiments, the impact-absorbing core may include foam beads, a foam block, or other materials capable of capturing and retaining an arrow. In some embodiments, the impact-absorbing core is at least partially formed from a self-healing material. Such self healing-materials may include, for example, small cell cellular plastic or rubber, open cell styrene butadiene rubber (SBR) foam, open cell styrene, or other materials capable of self-repair (e.g., filling a hole, sealing a gap, etc.) upon the removal of an arrow from the impact-absorbing core.
In some embodiments, process 200 may further include attaching to the multilayered bag at least one of: a handle, a grommet, and a mechanism for repeatable opening and closing of the multilayered bag (step 210). The handle may be a strap of fabric attached (e.g., sewn, riveted, adhered, etc.) to the multilayered bag at either or both ends of the handle. In some embodiments, an ergonomic grip (e.g., a rubber sleeve) may be added to the handle between the attached ends.
One or more grommets may be provided to hang the archery target in an elevated position as an alternative to resting the archery target upon the ground or other floor surface. The grommets may be holes through multilayered material 21 which are reinforced (e.g., with an inserted ring, with a reinforcing stitch, etc.) to provide durable locations for mounting multilayered material 21. Any number of grommets may be present. The mechanism for repeatable opening and closing of the multilayered bag may be a zipper, snaps, latches, hooks, buttons, or any other mechanism which allows for repeatable opening and closing of the multilayered bag.
