Definitions
- the present disclosure is directed to firearm supports, such as firearm shooting bags, configured for gas-assisted filling, and methods of filling firearm supports.
- Shooters often use shooting bags to support a firearm during target practice and accuracy testing.
- shooters can place the forestock of a rifle on a front bag and the buttstock of a rifle on a rear bag.
- the front bag is typically larger than the rear bag and can include an arcuate or v-shaped top surface sized to support the forestock of the rifle.
- the rear bag may include an arcuate or v-shaped surface sized to support the buttstock of rifle.
- Other shooting bags are sized to support the entire rifle or a portion of a rifle so that a second bag is not needed.
- one such shooting bag includes a long U- or V-shaped opening sized to receive several inches of a rifle stock to support the entire rifle. Additional shooting bags have different shapes designed for other applications.
- Conventional shooting bags include (a) a fabric or leather cover that encloses an internal cavity, and (b) particulate matter filling the entire internal cavity.
- One drawback associated with filling conventional shooting bags is the time and effort required to sufficiently pack the internal cavity with the particulate matter.
- a shooting bag should be firmly packed with the particulate matter so that the shooting bag retains its shape and provides a stable support for the firearm.
- filling conventional shooting bags often requires human interface to evenly distribute the particulate matter and ensure that the bags are firmly packed.
- shooting bags that are mechanically filled often require a dowel or similar device to tamp the particulate matter in the internal cavity.
- Gravity assisted methods of filling the internal cavity are also used, however gravity-assisted methods generally do not pack the bags firmly enough to provide adequate stability when supporting a firearm.
- the mechanical or gravity assisted methods of filling the bags therefore require additional steps and/or human interface that increase the time and expense of filling the bags. Accordingly, there exists a need to improve conventional shooting bags and the method of filling conventional shooting bags.

- the general shape of the body 112 may differ and is not limited to the embodiment illustrated in FIG. 1 .
- the body 112 further defines a cavity 120 configured for receiving and being filled with a filler material such as particulate matter 162 .
- the particulate matter 162 can include sand, dried rice, kitty litter or other suitable granulated media.

Description
- The present application claims priority under U.S.C. § 119(e) of U.S. Provisional Application No. 60/891,687, filed Feb. 26, 2007, the disclosure of which in incorporated herein by reference in its entirety.
- The present disclosure is directed to firearm supports, such as firearm shooting bags, configured for gas-assisted filling, and methods of filling firearm supports.
- Shooters often use shooting bags to support a firearm during target practice and accuracy testing. For example, shooters can place the forestock of a rifle on a front bag and the buttstock of a rifle on a rear bag. The front bag is typically larger than the rear bag and can include an arcuate or v-shaped top surface sized to support the forestock of the rifle. The rear bag may include an arcuate or v-shaped surface sized to support the buttstock of rifle. Other shooting bags are sized to support the entire rifle or a portion of a rifle so that a second bag is not needed. For example, one such shooting bag includes a long U- or V-shaped opening sized to receive several inches of a rifle stock to support the entire rifle. Additional shooting bags have different shapes designed for other applications.
- Conventional shooting bags include (a) a fabric or leather cover that encloses an internal cavity, and (b) particulate matter filling the entire internal cavity. One drawback associated with filling conventional shooting bags is the time and effort required to sufficiently pack the internal cavity with the particulate matter. A shooting bag should be firmly packed with the particulate matter so that the shooting bag retains its shape and provides a stable support for the firearm. Accordingly, filling conventional shooting bags often requires human interface to evenly distribute the particulate matter and ensure that the bags are firmly packed. For example, shooting bags that are mechanically filled often require a dowel or similar device to tamp the particulate matter in the internal cavity. Gravity assisted methods of filling the internal cavity are also used, however gravity-assisted methods generally do not pack the bags firmly enough to provide adequate stability when supporting a firearm. The mechanical or gravity assisted methods of filling the bags therefore require additional steps and/or human interface that increase the time and expense of filling the bags. Accordingly, there exists a need to improve conventional shooting bags and the method of filling conventional shooting bags.

FIG. 1 is a schematic side cross-sectional view of asystem 100 including a firearm support configured for gas-assisted filling in accordance with one embodiment of the invention. The illustratedsystem 100 includes afirearm support 110 that can be used to support a firearm (not shown) individually or with other firearm supports. For example, thefirearm support 110 can be configured for supporting a barrel, forestock and/or buttstock of the firearm. Thefirearm support 110 can also be configured for supporting one portion of the firearm in conjunction with another firearm support configured to support a different portion of the firearm. In other applications, thefirearm support 110 can be configured to support a firearm without the use of other firearm supports. - The
firearm support 110 includes abody 112 generally configured for supporting a firearm. Thebody 112 can be composed of an inorganic material, such as fabric, or an organic material such as leather. Thebody 112 can include multiple portions attached together forming thebody 112. For example, the illustratedbody 112 includes afirst portion 114 attached to asecond portion 116 configured to at least partially support a portion of the firearm. The first andsecond portions first portion 114 can be composed of a fabric, and thesecond portion 116 can be composed of leather, plastic, rubber or other non-marring materials. Although thefirst portion 114 and thesecond portion 116 are composed of generally flexible materials, in several embodiments the first orsecond portions - The
second portion 116 illustrated inFIG. 1 includes arecess 118 configured to at least partially receive a portion of the firearm. Therecess 118 has a generally U-shaped configuration to inhibit side-to-side movement of the firearm and support the firearm in an upright position. In other embodiments, thesecond portion 116 may include different shaped configurations, or thesecond portion 116 may not include arecess 118 for receiving a portion of the firearm. In other embodiments, the general shape of thebody 112 may differ and is not limited to the embodiment illustrated inFIG. 1 . - The
body 112 further defines acavity 120 configured for receiving and being filled with a filler material such asparticulate matter 162. Theparticulate matter 162 can include sand, dried rice, kitty litter or other suitable granulated media. Thebody 112 also includes aninlet 122 for introducing a combination of gas andparticulate matter 162 into thecavity 120. The inlet may be configured for receiving a nozzle (not shown) for introducing the gas andparticulate matter 162 in thecavity 120 during a gas-assisted filling process. Thebody 112 also includes anoutlet 124 configured to allow the gas to flow out of thecavity 120, as disclosed in more detail below. In the embodiment of thefirearm support 110 illustrated inFIG. 1 , theinlet 122 and theoutlet 124 are located on abottom surface 115 of thebody 112, however the locations of theinlet 122 and theoutlet 124 are not limited to thebottom surface 115. For example, theinlet 122 and/or theoutlet 124 can be located on thesecond portion 116 or on aside surface 117 of thebody 112. - The
outlet 124 is configured to retain theparticulate matter 162 in thecavity 120 and to allow gas to flow or escape from thecavity 120 during the gas assisted filling process. As indicated byarrows 126, gas can escape from thecavity 120 through theoutlet 124 simultaneously as the gas andparticulate matter 162 enter the cavity through theinlet 122. In several embodiments, theoutlet 124 may be composed of a material that is permeable to the gas but not to theparticulate matter 162. For example, theoutlet 124 may be composed of a material having a porosity that allows the gas to pass through theoutlet 124 while retaining theparticulate matter 162 in thecavity 120. Accordingly, the outlet may comprise a vent, valve, screen, mesh or other material. - The
system 100 further includes adelivery system 145 for delivering gas andparticulate matter 162 to thefirearm support 112. The delivery system includes agas source 150 and aparticulate matter source 160. A gas from thegas source 150 is combined with particulate matter from theparticulate matter source 160 and introduced in thecavity 120 through theinlet 122. For example, theparticulate matter 162 may be combined with the gas downstream from thegas source 150. According to alternative embodiments, a gas line from thegas source 150 can include a regulator 152, and a gas line from theparticulate matter source 160 can include a regulator 154. The regulators 152 and 154 allow a user to control the fill rate by controlling the amount of gas or particulate matter dispense. The regulators further allow different combinations and mixtures of gas or particulate matter for different bags. As the combination of gas andparticulate matter 162 enters and fills thecavity 120, theoutlet 124 permits the gas to escape from thecavity 120 as indicated by thearrows 126 while retaining theparticulate matter 162 in thecavity 120. - The
system 100 also includes anoptional pump 170, indicated by broken lines, that may be operably coupled to theoutlet 124 of thebody 112. Thepump 170 may consist of a vacuum or suction mechanism that evacuates the gas from thecavity 120 as the combination of the gas and the particulate matter is introduced in thecavity 120. Accordingly, in embodiments with thepump 170 coupled to theoutlet 124, thepump 170 may assist in removing the gas more quickly from thecavity 120 resulting in a faster filling time. - The disclosed
system 100 and firearm support configured for gas-assisted filling with particulate matter enables adequately filling of the firearm support bag with little or no human interface. For example, during a gas-assisted filling process where theparticulate matter 162 enters thecavity 120, gas is permitted to exit thecavity 120 through theoutlet 124, thus allowing the bag to fill with the particulate matter such that thefirearm support 110 is packed firm enough to support a firearm in a stable manner. Thesystem 100 also provides for a less-expensive and time consuming process, as additional steps of tamping or repacking the bag may not be required to adjust the amount ofparticulate matter 162 that fills thecavity 120. One skilled in the art will appreciate that thefirearm support 110 is also configured and suitable for use with gravity-assisted filling methods. For example, when theparticulate matter 162 enters thecavity 120 under the force of gravity, the configuration of theoutlet 124 allows air in thecavity 120 to escape as theparticulate matter 162 fills the cavity. -
FIG. 2A is a schematic isometric view of afirearm support 110 similar to the firearm support illustrated inFIG. 1 . InFIG. 2A and the following Figures, similar reference characters are used to indicate similar features of the embodiments. Referring toFIG. 2A , thesecond portion 116 of thebody 112 does not include arecess 118 as shown inFIG. 1 . Moreover, inFIG. 2A thebody 112 includes athird portion 202 extending away from thefirst portion 114 of thefirearm support 110. Thethird portion 202 may be formed of a flexible material that is the same as or different from the material that makes up thebody 112. For example, thethird portion 202 may be a sleeve or similar structure that contains theinlet 122 for introducingparticulate matter 162 in thecavity 120. In several embodiments, thethird portion 202 is configured to receive a nozzle 207 for introducing a combination of gas andparticulate matter 162 in thecavity 120. In certain embodiments, the nozzle 207 includes a positional indicia (shown in broken lines) 209 that indicates the depth of the nozzle insertion in thethird portion 202. For example, the indicia 209 can include a line or marking on the nozzle 207 that will align with a top end of thethird portion 202. In other embodiments, the indicia 209 is not used when the nozzle 207 is inserted in thethird portion 202. For example, a portion of the nozzle 207 can be sized to be approximately equal to the size of theinlet 122, such that thethird portion 202 will receive the appropriate insertion depth of the nozzle 207. Thethird portion 202 may also be configured to be closed after the gas-assisted filling process, such thatparticulate matter 162 cannot exit thecavity 120 through theinlet 122 after thethird portion 202 is closed. For example, aclosure mechanism 204 located in or on thethird portion 202 may close thethird portion 202, thus effectively closing theinlet 122, following the filling process. Theclosure mechanism 204 may include, but is not limited to, hook and loop mechanisms such as Velcro, buttons, snaps, a zipper, being sewn shut, or any other suitable mechanism for closing thethird portion 202. Alternatively, thethird portion 202 may not include aclosure mechanism 204 in several embodiments where thethird portion 202 is retained proximate to thebody 112, as described in more detail below. - The embodiment illustrated in
FIG. 2A also shows theoutlet 124 positioned proximate to thethird portion 202 on thebottom surface 115 of thefirst portion 114. It will be appreciated that theinlet 122 and theoutlet 124, as well as thethird portion 202, can be positioned at other locations around thebody 112. Similar toFIG. 1 , theoutlet 124 may be composed of a material that retains theparticulate matter 116 in thecavity 120 while allowing a gas to flow through theoutlet 124. For example, such a material may consist of, but is not limited to, a mesh orscreen material 220 that has a porosity different from the material of the first andsecond portions material 220 may be less durable than the materials of the other portions of thebody 112. -
FIG. 2B is a schematic isometric view of afirearm support 110 similar to the firearm supports illustrated inFIGS. 1 and 2A , according to another embodiment of the invention.FIG. 2B illustrates several different shapes of thebody 112 and configurations and placements of theoutlet 124. Referring toFIG. 2B , thesecond portion 116 does not include arecess 118 as shown inFIG. 1 , but rather a plurality of shallow recesses 119 a, 119 b and 119 c. It will be appreciated that the number or configuration of recesses may differ from that illustrated inFIG. 2B . Referring specifically toFIG. 2B , theoutlet 124 is shown as positioned on asidewall 206 of thethird portion 202. Theoutlet 124 may also be positioned to cover a portion of thesidewall 206 of thethird portion 202 in addition to an area proximate to thethird portion 202. For example, theoutlet 124 may be positioned on a portion of thesidewall 206 of thethird portion 202 while also positioned on at least part of the 115 bottom surface of thefirst portion 114, such that theoutlet 124 covers aninterface 208 of thesidewall 206 and thebottom surface 115. In other embodiments theoutlet 124 may also cover theentire sidewall 206 of thethird portion 202.FIG. 2B also illustrates a plurality ofoutlets particulate matter 162 in thecavity 120 while allowing gas to flow through the outlets 302 a-302 c. In several embodiments the outlet(s) may be shaped according to ease of manufacture and ability to retain theparticulate matter 162 while allowing sufficient airflow out of thecavity 120. For example, the shape and size of the outlet(s) may differ according to the size and shape of thefirearm support 110 and the location of the outlet(s). Accordingly, one skilled in the art will appreciate that single ormultiple outlets 124 having varying shapes may be placed in different locations around thebody 112. -
FIG. 2C is a schematic isometric view of afirearm support 110 similar to the firearm supports illustrated inFIGS. 1-2B , according to another embodiment of the invention.FIG. 2C illustrates a configuration of thebody 112 and placement of theoutlet 124 with respect to thethird portion 202. Referring toFIG. 2C , thesecond portion 116 does not include arecess 118 as shown inFIG. 1 , but rather, thebody 112 illustrates another shape suitable for supporting firearms. One side of thebody 112 may generally taper form thefirst portion 114 to thesecond portion 116 such that thefirst portion 114 is generally larger than thesecond portion 116. In the embodiment illustrated inFIG. 2C , thethird portion 202 can include both theinlet 122 and theoutlet 124. For example, thethird portion 202 may be divided between theinlet 122 and theoutlet 124 by fastening thethird portion 202 to itself, as represented by theseam 210 extending from the base to the top of thethird portion 202. In several embodiments, thethird portion 202 may be divided as described, or alternatively as separate portions or sleeves formed to contain theinlet 122 and theoutlet 124. As described above, a closure mechanism 204 (illustrated inFIG. 2A ) may be used to close thethird portion 202 containing theinlet 122 and theoutlet 124. Moreover,other outlets 124 located proximate to thethird portion 202 or on other portions of thebody 112 may be used. - The embodiment illustrated in
FIG. 2C also includes a nozzle 211 having a first nozzle portion 213 and a second nozzle portion 215. The first portion 213 introduces the gas and particulate matter into theinlet 122, and the second portion 215 vents the gas from theoutlet 124. In certain embodiments, the second portion 215 of the nozzle 211 includes a porous cover over the end of the second portion 215 to prevent the particulate matter from escaping from thesupport 110. The first and second portions 213 and 215 can be positioned in a larger housing 217 (shown in broken lines), or in alternative embodiments the first and second portions 213 and 215 can be secured together by a belt or band 219 (shown in broken lines). Moreover, in certain embodiments, the second portion can vent the gas from thesupport 100. For example, the second portion can be coupled to a pump or a vacuum source 221 (shown schematically) to remove the gas from theoutlet 124 of thesupport 110.FIG. 2C also illustrates a second nozzle 223 configured for gas-assisted filling of firearm supports. The nozzle 223 is inserted in a portion 225 that is configured similar to thethird portion 202 described above. Multiple nozzles and/or locations of nozzles enables uniform and sufficient filling of firearm supports. For example, supports having different shapes and sizes may require more than one nozzle to sufficiently pack the particulate matter during the filling process. -
FIG. 2D is a schematic isometric view of afirearm support 110 similar to the firearm supports illustrated inFIGS. 1-2C , according to another embodiment of the invention.FIG. 2D illustrates a configuration of theoutlet 124 located in afourth portion 402 extending away from thefirst portion 114. In several embodiments, thefourth portion 402 may have a similar structure to thethird portion 202 described above. For example, thefourth portion 402 may be a sleeve type structure containing theoutlet 124 for allowing the gas to escape from thecavity 120 while retainingparticulate matter 162. Moreover, thefourth portion 402 may be configured to be closed after the gas-assisted filling process with closure mechanisms similar to theclosure mechanism 204 described above regarding thethird portion 202. -

When thethird portion 202 is in a folded position, thethird portion 202 forms a generally planar surface with thebottom surface 115 to provide a stable support for a firearm. In additional, thethird portion 202 at least partially covers the outlet 124 (shown in broken lines) when thethird portion 202 is folded. Covering theoutlet 124 protects theoutlet 124 which may be composed of a material less durable than the material of the other portions of thebody 112. One skilled in the art will appreciate that the third portion can be located and folded at other positions on thebody 112, such as theside surface 117. In several embodiments, thefourth portion 402 ofFIG. 2D may also be folded in a manner similar to thethird portion 202 as illustrated inFIG. 2E . Accordingly, thethird portion 202 may at least partially cover thefourth portion 402 and form a substantially planar surface when the portions are folded proximate to theback surface 115. - In addition to folding the
third portion 202 proximate to theback surface 115, thethird portion 202 may also be at least partially retained proximate to the back surface 115 (or other surfaces where thethird portion 202 is located). In several embodiments, astrap 502 may be used to retain thethird portion 202. Thestrap 502 may be connected to thefirst portion 114 of thebody 112 at theends 504 of thestrap 502. Accordingly, thethird portion 202 may be tucked under thestrap 502 after the gas-assisted filling process. If afourth portion 402 is used, the fourth portion may also be retained by the strap 502 (not shown inFIG. 2E ). Other holding mechanisms may be used to retain thethird portion 202 proximate to thebody 112. For example, the third portion may be retained against theback surface 115 by a hook and loop mechanism such as Velcro, buttons, snaps, a zipper, being sewn shut, or any other suitable mechanism for retaining thethird portion 202. In other embodiments, a pocket (not shown) may be formed with the material of theback surface 115 such that thethird portion 202 may be tucked into and retained by the pocket. -

FIG. 4 is a schematic isometric view of afirearm support 410 in accordance with another embodiment of the invention. Thefirearm support 410 is generally similar to the firearm supports described above. For example, thefirearm support 410 includes abody 412 defining a cavity, and afirst portion 414 and asecond portion 416. In several embodiments, thefirst portion 414 may be composed of afirst material 420 having a first porosity and asecond material 422 having a second porosity different from the first porosity. For example, thesecond material 422 may comprise a relatively small portion of thefirst portion 414 in relation to thefirst material 420. Accordingly, the second material may comprise a gas exit region (not shown). Thesecond portion 416 may be composed of athird material 418 having a third porosity different from the first and second porosities. Thethird material 418 may be suitable for contacting a firearm, such as leather or other non-marring materials. Similar to the firearm supports described above, thefirearm support 410 may include an inlet (not shown) for receiving a combination of a gas and particulate matter, and an outlet for allowing the gas to escape from the cavity while retaining the particulate matter. In several embodiments, the combination of the first, second and third porosities is configured to allow the gas to flow through the first portion and exit the cavity during a gas-assisted filling process while retaining the filler material in the enclosure. For example, the third porosity may be configured to generally not be permeable to the gas. In addition, the second porosity may be configured such that the majority of the gas will exit the cavity through thesecond material 402. -
FIG. 5 is a flow diagram illustrating aprocess 500 that can be used to fill thefirearm support 110 described above. Theprocess 500 can include flowing a gas toward a firearm support at ablock 510. At ablock 520, particulate matter is also directed toward the firearm support. The gas and the particulate matter can be combined at ablock 530. In some embodiments, a particulate matter source may be positioned downstream from a gas source. Accordingly, particulate matter may be combined with the gas downstream from the gas source. Those skilled in the art will appreciate that the gas and particulate matter can be combined using other methods. At ablock 540, the combination of the gas and particulate matter is introduced in the firearm support and into a cavity defined by a body of the firearm support. In some embodiments the combination of gas and particulate matter may be introduced into an opening in the firearm support configured to receive the combination of gas and particulate matter. While the combination of gas and particulate matter is being introduced into the firearm support, at ablock 550 the gas may be evacuated from the firearm support while retaining the particulate matter in the cavity. In some embodiments, evacuating the gas may comprise allowing the gas to flow through an outlet of the cavity during the filling process. The outlet may be configured to allow the gas to flow out of the cavity while retaining the particulate matter. For example, the outlet may comprise a valve or a screen or mesh material. Moreover, in some embodiments the gas may also be removed from the cavity. For example, a pump may be operatively coupled to the outlet of the cavity. The pump may create a suction to remove the gas while retaining the particulate matter. - The
process 500 accordingly provides for an efficient method of filling firearm supports with particulate matter. Evacuating the gas from the firearm support while the combination of gas and particulate matter is introduced into the firearm support provides for efficient and adequate packing of the particulate matter. Theprocess 500 enables a bag to be completely filled without using other devices or means to tamp or evenly distribute the particulate matter throughout the cavity to sufficiently fill the cavity and form a stable firearm support. -
FIG. 6 is a flow diagram illustrating aprocess 600 that can be used to construct thefirearm support 110 described above. Theprocess 600 can include constructing a body having a generally flexible enclosure at ablock 610. The body may be composed of one or more portions attached together according to the embodiments of the firearm supports described above. The body also defines a cavity that may be filled with filler material, such as particulate matter. At ablock 620 an inlet in the cavity is formed. The inlet is configured to receive a gas and particulate matter into the cavity to fill the cavity. At ablock 630 an outlet in the cavity is formed. The outlet is configured to allow the gas to escape from the cavity while retaining the particulate matter in the cavity. The outlet may consist a material having a porosity that is permeable to the gas but not to the particulate matter. Theprocess 600 accordingly provides a method of constructing a firearm support that is configured to be efficiently and adequately filled with particulate matter requiring little human interface. - From the foregoing, it will be appreciated that specific embodiments of the invention have been described herein for purposes of illustration, but that various modifications may be made without deviating from the invention. Furthermore, aspects of the invention described in the context of particular embodiments may be combined or eliminated in other embodiments. Further, while advantages associated with certain embodiments of the invention have been described in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the invention. Accordingly, the invention is not limited, except as by the appended claims.
