Not applicable.
The application relates generally to targets including archery targets.
Various targets are commercially available for enthusiasts of firearm shooting, archery and other aiming activities. Some targets are offered as a single or one-piece item. In other instances, targets are provided with a target holder portion that serves as a base structural support or frame for holding a replaceable aiming target portion. Some targets used by hunters are provided with a structural support portion in the form of a three-dimensional animal and a removable aiming target held by the support portion at one or more desired locations for aiming purposes. In other instances, a whole three-dimensional animal type structure may serve as a target. In the above examples, the target and/or target holder is often formed of molded foam having a shape resembling that of a game animal, e.g., a bear, deer, elk. Although offered as “life-size,” many game animal targets are actually smaller than the size of the animal as encountered in the wild, which works against proper aiming or targeting of the animal for future real world encounters. While other three-dimensional animal-simulating targets may be more closely provided as “life-size,” such targets are often costly to manufacturer according to their three-dimensional shape and are relatively expensive for consumers to purchase. Also, the molded foam used to construct the target and/or target holder may be subject to destruction over time resulting in additional replacement costs.
Still other hunting type targets are provided with overlays that simulate the perimeter shape and appearance of particular game animals and have openings there through representing areas of vital organs to be impacted by projectiles. Replaceable targets are typically located at the openings for targeting purposes. Such overlays are typically constructed from one or more solid materials such as wood, plastic, metal, or one or more lightweight materials such as foam and/or lightweight plastic. In certain instances, the materials of construction are sometimes provided as hard or solid resulting in structural damage to certain projectiles upon impact, e.g., arrows, spears, darts, etc. In other instances, the materials of construction are soft or too lightweight whereby one or more projectiles, e.g., arrows, spears, darts, etc., pass through the overlay subjecting persons and objects located behind the overlay to being struck by such projectiles.
Overcoming the above shortcomings is desired.
The present disclosure is directed to a target system, including (1) one or more targets and (2) a support for the one or more targets including a main body having a front surface, a rear surface, one or more openings there through, one or more rear surface items including one or more landing surfaces operationally configured to hold the one or more targets at the one or more openings; wherein the main body includes an inner section and an outer section covering the inner section.
The present disclosure is also directed to a support for holding a projectile target, including (1) a main body having (a) an outlay design; (b) a front surface having an appearance corresponding to the outlay design; (c) an opening located along the main body according to the outlay design and front surface appearance of the main body; and (d) a rear surface; and (2) a frame type member secured to the rear surface of the main body and operationally configured to hold a projectile target at the opening, the frame type member including one or more elongated members further operable as backing members disposed along the rear surface according to the outlay design.
The present disclosure is also directed to a method of making a support for a projectile target, comprising (1) forming a main body of a support including one or more openings in the main body and one or more rear surface items from a single sheet of closed cell extruded polystyrene foam; (2) assembling the main body and one or more rear surface items to form an inner section of the main body; and (3) spraying a coating onto the main body and one or more rear surface items to form an outer section of the main body.

Similar as the grizzly bear embodiment of
Without limiting the invention, the first member 10 may be constructed from one or more materials including, but not necessarily limited to materials resistant to chipping, cracking, excessive bending and reshaping as a result of weathering, heat, moisture, other outside mechanical and chemical influences, as well as impacts and forces applied to the first member 10. In an embodiment intended for archery type operations, the first member 10 may include a first body section 45 alone or further include a second body section 47 covering all or a portion of the outer surface of the first body section 45. Herein, the first body section 45 may also be referred to as an “inner section” of the first member 10 and the second body section 47 may also be referred to as an “outer section” of the first member 10.
Suitably, the first member 10 described above is operationally configured as a support for one or more second members 12 and not necessarily operationally configured as a target. However, it is contemplated that the first member 10 may be constructed from one or more materials effective to receive impacts from projectiles in a target like manner. For example, in an embodiment including a first member 10 intended to hold a second member 12 such as an archery target at or near its opening 17, the first member 10 may include a first body section 45 constructed from one or more materials comprising a density effective to (1) stop and retain a tip section of an arrow without the tip section penetrating or otherwise breaking through the rear surface 18 of the first member 10, and (2) maintain the operable shape of the first member 10 without bending, breaking or otherwise deforming although such is not necessarily required for operability of the first member 10. In another embodiment, the first body section 45 may be constructed from one or more materials allowing passage of an arrow completely through the first member 10, e.g., where the first member 10 is to be used in an open area such as an open field, an interior location, against a wall or other barrier, thereby eliminating or minimizing the threat of an arrow traveling out past the first member 10 and striking person(s) and/or object(s).
For archery type operations, one suitable second body section 47 may include an outer skin type configuration formed from one or more layers of solid material(s) and/or one or more layers of one or more coatings, e.g., one or more flowable coatings, covering all or a portion of the first body section 45. In one particular embodiment for archery type operations, the second body section 47 may be comprised of one or more resilient materials effective to completely or at least partially return to its original state or condition once an arrow having penetrated the second body section 47 is removed or otherwise separated from the first member 10.
Exemplary materials of construction of the first body section 45 may include, but are not necessarily limited to polymeric materials, woods, feathers, cork, sand, paper products including recycled paper products, textiles, cotton, coconut fiber, crumb rubber, bamboo infused foam, and combinations thereof. Suitable polymeric materials may include, but are not necessarily limited to foam including, but not necessarily limited to polyethylene foam, polystyrene foam (e.g., extruded polystyrene foam (“XPS”), expanded polystyrene foam (“EPS”)), polyurethane foam (e.g., closed-cell foam, open-cell foam), polyester, compressed polyester, polyester fiber fill, synthetic rubbers, and combinations thereof. One suitable type of synthetic rubber includes, but is not necessarily limited to neoprene, e.g., neoprene sheets.
Exemplary materials of construction of the second body section 47 may include, but are not necessarily limited to polyurethane coatings (e.g., hand brush coatings, spray coatings, and combinations thereof), polyurea coatings (e.g., hand brush coatings, spray coatings, and combinations thereof), polyurethane-urea hybrid coatings (e.g., hand brush coatings, spray coatings, and combinations thereof), epoxy coatings, stretch wrap materials, vinyl wrap materials, tapes, rubber coatings, acrylic coatings, paper products, textiles, fiberglass, woven fiberglass tape, and combinations thereof. Suitable rubber coatings may include, but are not necessarily limited to silicone coatings, ethylene propylene diene monomers (“EPDM”) coatings, and combinations thereof. Suitable textiles may include, but are not necessarily limited to cotton fabrics, polyester fabrics, canvas, denim, continuous filament basalt (volcano rock) fiber wrap, nylon, ripstop fabrics (e.g., ripstop nylon and ripstop polyester), and combinations thereof.
As stated above, the first member 10 of this disclosure may be built to scale. Accordingly, the first member 10 may include a maximum thickness as desired for workability and/or for ease of transport of the first member 10 based on the one or more materials of construction as may be required for one or more particular operations. The first member 10 may also include a minimum thickness as desired or as otherwise required for one or more particular operations and/or according to the one or more materials of construction of the first member 10. Likewise, the thickness of the second body section 47 may vary as desired or as otherwise required for one or more particular operations. In addition, the proportions of the first body section 45 and the second body section 47 in regard to thickness of the first member 10 may vary according to one or more intended uses of the first member 10. For example, in an embodiment where a first member 10 may serve for both archery and non-penetrable projectile use (e.g., paintball targeting via a paintball gun), the proportion of the second body section 47 may be increased compared to other embodiments of the first member 10, i.e., the second body section 47 may be made thicker, to withstand impacts from projected paintballs traveling at speeds ranging from 73.2-85.3 meters per second (240.0-280.0 feet per second). Without limiting the disclosure, one exemplary first member 10 may include a second body section 47 having a thickness ranging from or about 0.16 cm to or about 1.91 cm (from or about 0.0625 inches or 1/16 inches to or about 0.75 inches or ¾ inches).
For archery type applications in general, one exemplary first member 10 including a first body section 45 constructed from foam, e.g., polyethylene foam, polystyrene foam, polyurethane foam, may include a first body section 45 with a maximum thickness and a minimum thickness as listed in Table 2:
In regard to an archery type first member 10 provided as a life size game animal such as the grizzly bear as shown in
As such, in one exemplary embodiment of an archery type first member 10 wherein the average thickness of the first body section 45 is 5.08 cm (2.0 inches) and the average thickness of the second body section 47 is 0.0625 inches or 1/16 inches, the second body section 47 comprises about three percent of the thickness of the first member 10. In an embodiment of an archery type first member 10 wherein the average thickness of the first body section 45 is 5.08 cm (2.0 inches) and the average thickness of the second body section 47 is 0.281 inches or 9/32 inches, the second body section 47 comprises about twelve percent of the thickness of the first member 10. In an embodiment of an archery type first member 10 wherein the average thickness of the first body section 45 is 5.08 cm (2.0 inches) and the average thickness of the second body section 47 is 0.32 cm (0.125 inches or ⅛ inches), the second body section 47 comprises about six percent of the thickness of the first member 10 (see dimension D1 in
Persons of ordinary skill in the art will recognize that the thickness of the first member 10 may vary without altering the workability of the first member 10. Persons of ordinary skill in the art will also recognize that an arrow is commonly projected through the air via a bow or crossbow from about 12.2 meters per second up to about 121.9 meters per second (from about 40.0 feet per second up to about 400.00 feet per second) depending on the make/model of the bow, age of person shooting the arrow, the type of arrow used, ambient wind conditions and/or other ambient weather conditions. As stated above, the first member 10 is operationally configured as a support for one or more second members 12 and not necessarily operationally configured as a target. However, a person of ordinary skill in the art will appreciate that it is plausible that a first member 10 may be constructed according to an anticipated arrow velocity and/or arrow(s) design and/or type of arrow(s) including the materials of construction of an arrow tip section to be used with the system effective to stop and retain such arrow(s) in the first member 10 without the tip section of an arrow traveling out past the rear surface 18 in the event that such arrow misses a targeted second member 12.
Persons of ordinary skill in the art will also recognize that the first member 10 may have a total weight according to the one or more materials of construction and one or more anatomical features included as part of the first member 10. As such, the first member 10 is not necessarily limited to any particular maximum weight. However, in an embodiment of the first member 10 configured for archery use the first member 10 suitably has a total weight light enough for the first member 10 to be manually lifted and/or transported by one or two persons. For example, the grizzly bear styled first member 10 of
The one or more materials of construction of the first body section 45 and one or more rear surface items may be formed or shaped as desired. In one embodiment, a first member 10 may be provided as a one-piece material cut down to an intended shape and size including cutting out one or more openings 17, e.g., a naked first body section 45 provided without the inclusion of a second body section 47. Without limiting the invention, one exemplary first member 10 and corresponding one or more rear surface items may be constructed from a solid board type material and shaped to size via one or more cutting instruments, e.g., via one or more of a CNC machine, a laser, a water jet cutter, a saw blade, a knife, a razor blade, scissors. Although the first body section 45 may be built to scale, a one-piece board type material for forming a first body section 45 representing a life size game animal may include the following dimensions: (1) 243.8×121.9×5.1 cm (96.0×48.0×2.0 inches); (2) 243.8×121.9×10.2 cm (96.0×48.0×4.0 inches).
As shown in
In another embodiment, the first member 10 may be formed via a particular size and shape mold using one or more materials as described above. For example, a first member 10 may be formed via foam injection molding. In another embodiment, a first member 10 may be formed by pouring a flowable fluid comprising one or more of the above described materials into a mold of a desired size and shape for curing. As such, a suitable flowable fluid may also comprise one or more filler materials, one or more resins, one or more epoxies, and combinations thereof providing a solid member for use as part of the present system.

In one implementation, assembly may include abutment of at least part of the frame type member 24 with one or more backing members 35 and/or abutment of two or more backing members 35 and/or and one or more stake holders 25 whereby the second body section 47 covers the frame type member 24, one or more backing members 35 and one or more stake holders 25 in a manner effective to hold each in a fixed position for use as part of the first member 10. With reference to
In another implementation, assembly may include fastening part of the frame type member 24 to part of one or more of the backing members 35 and/or one or more stake holders 25 and/or fastening two or more backing members 35 together and/or fastening one or more backing members 35 to one or more stake holders 25 via one or more fasteners, e.g., screws, rods, bolts/nuts, and combinations thereof. In another implementation and depending on the materials of construction used, assembly may include adhering part of the frame type member 24 to one or more backing member 35 and/or adhering two or more backing members 35 together via heat, e.g., a heat gun, torch. In another implementation, assembly may include adhering part of the frame type member 24 to one or more backing members 35 and/or one or more stake holders 25 and/or adhering two or more backing members 35 together and/or adhering one or more backing members to one or more stake holders 25 via one or more adhesives, e.g., glue, epoxy, paste, and combinations thereof. In another implementation, a threaded stitch and/or tape may be used to attach one or more of the frame type member 24, one or more of the backing members 35 and/or one or more stake holders 25. In another embodiment, a frame type member 24 and backing members 35 as shown, for example, in
As shown in the various figures as described above, the support member 20, frame type member 24, backing members 35 and stake holders 25 are provided as elongated rectangular members, e.g., plank type members, board type members, sheet type members. In another embodiment, the support member 20 and/or backing members 35 and/or stake holder 25 may be provided in other three-dimensional configurations, including rounded surfaces as shown in
A discussion concerning the manufacture of one non-limiting embodiment of a first member 10 is presented below. The skilled artisan will appreciate that the details described below may be considered as part of the manufacturing process of a first member 10 generally, regardless of the size, shape and appearance of the first member 10. For demonstrative purposes, manufacture of a first member 10 is described below in relation to manufacture of a first member 10 for archery use provided as a life size game animal in the shape and appearance of a grizzly bear as shown in
Choice of Materials of the First Body Section 45 of the First Member 10
The material of construction for the first body section 45 of the first member 10 includes a sheet of closed cell extruded polystyrene foam with an RSI value of 0.88 (R-value of 5.0). The sheet of closed cell extruded polystyrene foam or “XPS” is provided in the following dimensions:
One suitable commercially available XPS includes Styrofoam® Insulation Blue Board from The Dow Chemical Company, Midland, Michigan, U.S.A. (“Dow”). For archery type operations, closed cell XPS provides one or more of the following qualities: (1) XPS has a density strong enough to withstand the manufacturing process including handling and shape forming of the first member 10; (2) heat resistance; (3) water resistance; (4) XPS has the ability to maintain or hold its shape over extended periods of time making it suitable for shaping into a plurality of silhouette forms including the forms depicted as part of this disclosure; (5) XPS cuts fairly easy making it suitable for shaping into a plurality of silhouette forms; and (6) XPS maintains its integrity without material breakdown when applying a second body section 47 including a hand brush coating and/or spray coating as described above.
Forming the Perimeter Shape or Silhouette of the First Member 10
Once a desired game animal shape or silhouette is chosen, e.g., a grizzly bear form, an outlay design of a desired grizzly bear form is prepared e.g., drafted on paper via a hand drawing and/or via a computer drawing. Once a desired grizzly bear outlay design is completed, one or more additional details to be included along the front surface 15 of the first member 10 may be determined as well as the size, shape and location of the one or more openings 17 in accordance with the location of vital organs of the grizzly bear based on the outlay design. Thereafter, the size, shape, type and location of rear surface items such as a ledge type member 21, frame type member 24 including the backing members 35, and one or more stake holders 25 are determined for use along the rear surface 18 of the first body section 45 in accordance with (1) the size or surface area and shape of the rear surface 18 of the first body section 45, (2) the size, shape and location of the one or more openings 17, (3) the amount of backing structural support needed for operation of the first member 10, and (4) the amount of support needed by the support member 20.
Once the grizzly bear outlay design and corresponding parts are determined, a sheet of XPS can be readied for forming into the grizzly bear outlay design on a life size scale. First, the computer drawings and/or hand drawings of the grizzly bear outlay design are converted into computer files, e.g., .dxf files, readable by a CNC router machine operationally configured to cut along three axes (Z, Y and Z). One non-limiting example of a commercially available CNC router machine includes the G3 Digital Cutter commercially available from Zünd Systemtechnik AG, Altstätten, Switzerland. As understood by the skilled artisan, original computer drawings may be uploaded directly to a CNC router machine. As also understood by the skilled artisan, .dxf files suitably provide the CNC router machine with information concerning where the CNC router machine will enter the XPS material, the path the CNC router machine will follow and the depth of the router bit within the XPS material during operation. In one suitable mode of operation, the CNC router machine begins the cutting process by cutting or otherwise forming the perimeter silhouette of the grizzly bear and the opening 17. Thereafter, the CNC router machine routes out any front surface 15 details as programmed. For example, the CNC router machine may route out one or more anatomical features of the grizzly bear. Also, the CNC router machine may form one or more depressions or cavities in the front surface 15 for receiving eyes, claws and teeth therein.
For purposes of forming a life size game animal silhouette such as a grizzly bear, a CNC router machine is effective in that it achieves smooth cuts in the XPS material and is capable of routing intricate details on the front surface 15 of the first member 10. Persons of ordinary skill in the art will appreciate that even though a life size game animal silhouette may be formed by hand using one or more cutting instruments, such a task may be time consuming and physically exhausting.
Another advantage to using a sheet of XPS with the dimensions as described above to form a grizzly bear styled first member 10 as shown in

Once the first body section 45, support member 20, frame type member 24, backing members 35 and stake holders 25 are cut out of a sheet of XPS, each is attached to the rear surface 18 of the first body section 45 via an adhesive, e.g., Loctite® PL300 adhesive commercially available from Henkel Corporation, Westlake, Ohio, U.S.A. The adhered component parts may be allowed to cure for about twenty-four hours.
Loctite® PL300 adhesive, or equivalent, is suitable for the following reasons: (1) Loctite® PL300 adhesive has desirable adhesive properties for use with foams including XPS, (2) Loctite® PL300 adhesive does not affect the material integrity of the XPS upon contact, (3) Loctite® PL300 adhesive's cure time is relatively short thereby minimizing the product time for the first member 10, (4) Loctite® PL300 adhesive is water soluble making it environmentally friendly and allowing for ease of clean up; and (5) Loctite® PL300 adhesive is recommended by Dow for use with their XPS products.
Addition of the Second Body Section 47 to the First Body Section 45
Once the Loctite® PL300 adhesive is cured, the first body member 10 is ready to receive its second body section 47 in the form of a polyurea elastomer spray (“spray coating”) that is a reacted product of two components that are mixed and sprayed onto the first body section 45 in one or more passes. The first component (the “A” component) of the spray coating is UL XT 66, A-side and the second component (the “B” component) is UL XT 66, B-side, both of which are commercially available from Ultimate Linings, located in Houston, Texas, U.S.A.
UL XT 66, A-side (the “A” component) is comprised of:
UL XT 66, B-side (the “B” component) is comprised of:
The spray coating is suitable for use with XPS for the following reasons: (1) the spray coating adheres directly to the XPS forming a one-piece first member 10; (2) the spray coating adheres the various component parts to the first body section 45 together thereby enhancing the structural stability of the first member 10 during operation; (3) the spray coating is resistant to ultra-violet (“UV”) radiation, i.e., “UV resistant,” allowing the first member 10 to be exposed to direct sunlight for many years without structural degradation to the spray coating or fading in color; and (4) the spray coating does not affect the material integrity of the XPS upon contact with the XPS.
Another feature of the present disclosure is the system of equipment and process by which the spray coating is applied to the XPS. In order to effectively spray the spray coating, the system equipment is operationally configured to store, pump, heat, mix and spray the two components of the spray coating at a desired temperature, pressure, viscosity and material ratio. Control of such factors produces a desired first member 10 having a functionally desired second body section 47 for archery purposes.
In general, a volume of the “A” component and a volume of the “B” component are provided in separate fluid containers such as drums, tanks or the like and are mixed together during spraying operations as the “A” component and the “B” enter a spray gun at a desired temperature and volume to provide a homogeneous mixture exiting the spray gun. In particular, a fluid proportioner is provided having a first heated fluid conduit, e.g., a hose, in fluid communication with a first container housing the “A” component and a second heated fluid conduit, e.g., a hose, in fluid communication with a second container housing the “B” component. The first heated fluid conduit is operationally configured to condition the “A” component to a desired viscosity prior to mixing and the second heated fluid conduit is operationally configured to condition the “B” component to a desired viscosity prior to mixing. Said another way, the first heated fluid conduit and the second heated fluid conduit are each operationally configured to heat corresponding spray coating components and maintain the spray coating components at a desired temperature(s). In addition, a fluid proportioner is operationally configured to pressurize the spray coating components to a desired constant pressure while also maintaining an optimal ratio of the “A” and “B” components for mixing. One exemplary fluid proportioner for manufacture of the first member 10 may include the Graco® E-XP1 or the A-XP1 Reactor coatings proportioner commercially available from Graco Inc., Minneapolis, Minnesota, U.S.A. In addition, fluid proportioner operations are described in U.S. Pat. No. 9,221,669 B2, titled “Waste Heat Recovery System for Pumping System,” issued Dec. 29, 2015; U.S. Pat. No. 8,568,104 B2, titled “Fast Set Material Proportioner,” issued Oct. 29, 2013, each of which is hereby incorporated by reference in its entirety.
In operation, the pressure of the first and second fluid conduits is maintained at or about 16202.7 kPa (2350.0 PSI) and the internal temperature of the first and second heated fluid conduits, i.e., the temperature of the “A” component and the “B” component, are each maintained at a constant temperature of or about 68.3° C. (155.0° F.) as the two components enter a mixing chamber within the spray gun. Suitably, the “A” and “B” components are mixed at a 1:1 ratio at 68.3° C. (155.0° F.) within a mixing chamber of the spray gun producing an exothermic reaction that causes the temperature of the mixture to increase to a spray application temperature from or about 85.0° C. (185.0° F.) to or about 98.9° C. (210.0° F.). At pressures below or above 16202.7 kPa (2350.0 PSI), the “A” component and the “B” component will not properly mix resulting in poor or over atomization of the spray coating or lack atomization altogether. At temperatures less than 68.3° C. (155.0° F.), the reaction between the “A” component and the “B” component will not produce the desired polymerization of the spray coating. As such, at undesired pressures and temperatures, the resulting spray coating does not properly adhere to the surface of the XPS. Moreover, at temperatures greater than 98.9° C. (210.0° F.), the spray coating is hot enough to melt, deform and/or otherwise damage the integrity and appearance of the surface of the XPS upon contact. At temperatures less than 85.0° C. (185.0° F.), the spray coating is not hot enough to maintain a liquid form suitable for proper spraying of the spray coating onto the surface of the XPS. One non-limiting example of a commercially available spray gun for use as part of the present disclosure includes the FUSION® AP Spray Gun available from Graco Inc., Minneapolis, Minnesota, U.S.A. In addition, an exemplary spray gun is described in U.S. Pat. No. 7,694,893, titled “Plural Component Spray Gun for Fast Setting Materials,” issued Apr. 13, 2010, which is hereby incorporated by reference in its entirety.
As understood by persons of ordinary skill in the art of fluid proportioners, the amount of time necessary to reach the desired spray temperature of 68.3° C. (155.0° F.) may vary based on the ambient temperature. For example, an ambient temperature of 15.6° C. (60.0° F.) will require a longer heating process than an ambient temperature of 32.2° C. (90.0° F.). A fluid proportioner, including the Graco E-XP1 or the A-XP1 Reactor coatings proportioner, is operationally configured to be programmed to heat the “A” component and the “B” component each to a desired temperature and provide a digital readout signaling to user(s) when the desired temperature of the “A” and “B” components is reached. As also understood by persons of ordinary skill in the art of fluid proportioners, a fluid proportioner, including the Graco E-XP1 or the A-XP1 Reactor coatings proportioner, is operationally configured to regulate the temperature and pressure of the “A” component and the “B” component via temperature and pressure controls, and is also operationally configured to monitor the mixture composition to ensure that the mixture undergoes a desired exothermic reaction. If the fluid proportioner detects that the temperature and/or pressure of either the “A” component or the “B” component is higher or lower than the programmed working temperature and pressure, the fluid proportioner is operationally configured to be directed to an OFF position to protect the component parts of the fluid proportioner and/or the spray gun from unwanted damage.
As understood by the skilled artisan, a second body section 47 in the form of a permanent polymer spray coating, e.g., polyurethane coatings, polyurea coatings, polyurethane-urea hybrid coatings, may be provided in a thickness according to the amount of spray coating that is applied to the first body section 45. As also understood by the skilled artisan, the thickness of the second body section 47 may affect its mechanical characteristics. Typically, the more passes made when applying the spray coating, the thicker the resulting second body section 47. In regard to the “A” component UL XT 66, A-side and the “B” component UL XT 66, B-side, suitable thicknesses of the second body section 47 may be formed according to the number of spray passes as described in Table 5:
To form an effective second body section 47, the spray nozzle used is suitably held apart from the first body section 45 during each spray pass at a distance from or about 60.96 cm (24.0 inches) to or about 91.4 cm (36.0 inches).
In addition, the first body section 45 of the life size grizzly bear of
The spray coating described above suitably dries in about seven (7.0) seconds once the spray coating contacts the first body section 45. The dry time may vary depending on the ambient temperature and/or humidity. The spray coating suitably cools to room temperature and cures in a period of about two to three hours.
The spray coating may be formulated to include any color as desired. For example, a brown pigment or combination of pigments forming a brown color may be added to the spray coating to provide a brown colored second body section 45 as shown in
First Member 10 Surface Finishing Details
By customizing the color of the spray coating of the first member 10, the total amount of surface mediums otherwise required to provide an accurate brownish color to the first member 10 is minimized or otherwise eliminated depending on the desired final surface appearance of the grizzly bear styled first member 10. As such, additional expense can be focused on the addition of one or more finishing details to the first member 10 as described above. Items such as hair, taxidermy eyes, taxidermy claws, and taxidermy teeth may be secured to the surface of the first member 10 via one or more adhesives, tapes, fasteners, and combinations thereof. For example, hair may be secured to the first member 10 via fasteners including, but not necessarily limited to staples, nylon sutures, and combinations thereof.
In another embodiment, a second body section 47 in the form of a polyurea elastomer spray (“spray coating”) may be provided including an “A” component and a “B” component. The “A” component may be comprised of:
The “B” component may be comprised of:
