1. Field of the Invention
The present invention relates generally to firearm holding devices, and more specifically to firearm holding devices for cleaning and maintaining a firearm.
2. Discussion of the Related Art
Traditionally, a firearm such as a shotgun or handgun is either handheld during maintenance or cleaning, or held securely by a standard metal machinist vise or shop vise. However, machinist or shop vises are not designed for firearm restraint and may, for example, damage the finish of the firearm or restrain the firearm in a position inconvenient for the user.
Handgun holding devices found in the prior art commonly support the handgun in a position where the plane of the gun is vertical, i.e. either in a firing position or with the barrel oriented in a vertical direction.
Adjustable portions of the handgun holding device typically allow for the firearm to be placed in the holding device and then secured. Other adjustable portions may allow for various firearm shapes and sizes to be secured by the same holding device.
Firearm holding devices may also support the firearm in a horizontal position so that firearm pins are in a vertical position and the handgun is supported when the pins are punched or hammered out. While horizontal holding devices typically provide support for the entire firearm, because the holding device must be designed to support the varying profile of the firearm, the ability of the firearm holding device to support varying shapes and sizes is limited.
Another characteristic found in firearm holding devices is one or more areas for holding portions of the firearm removed during maintenance, for example, the trigger.

The front top frame projection 118 and the rear top frame projection 120 also provide rigidity and support to the firearm support apparatus 100 when the bottom face 200 is upwards.
The center top frame projection 122 provides additional rigidity and support to the support plate 102 during firearm 1300 maintenance when the bottom face 200 is facing upwards.
The thumb safety 1900 projects from a side of the firearm 1300. The thumb safety cutout 126 provides the necessary clearance around the thumb safety 1900 so that the firearm 1300 may be supported in the horizontal position on the firearm support apparatus 100. The thumb safety cutout 126 also allows for access to the thumb safety 1900 from the opposite side of the firearm support apparatus 100, i.e. when the firearm 1300 is coupled to the top face 112 and the thumb safety 1900 is proximate to the top face 112, the thumb safety 1900 is accessible through the thumb safety cutout 126 when the firearm support apparatus 100 is rotated such that the bottom face 200 faces upwards.
The thumb safety cutout 126 is shaped to provide clearance for the thumb safety 1900 when the thumb safety 1900 is in both a fire position 1904 and a safe position 1902, as shown below in
Similarly to the thumb safety cutout 126, the slide lock lever cutout 124 is configured to provide clearance for a slide lock lever of the firearm 1300 when the firearm 1300 is coupled to the firearm support apparatus.
The first boss cutout 130 is located proximate to the rear edge 110 of the support plate 102 and provides a first attachment and sliding adjustment area for the first moveable boss 300. The second boss cutout 136, located proximate to a midpoint of the magazine edge 106, provides a second attachment and sliding adjustment area for the second moveable boss 302. The first and second moveable bosses 300, 302 are used to provide demountable coupling of the firearm 1300 to the firearm support apparatus 100 and also to allow for coupling of different sizes and shapes of firearms 1300. The attachment and adjustment of the first and second moveable bosses 300, 302 are shown below in
The sear housing pin cutout 132 located proximate to the first boss cutout 130 and the thumb safety cutout 126 is configured to provide clearance and access for the sear housing pin 1400 of the firearm 1300 to be removed from the firearm 1300 when the firearm 1300 is coupled to the firearm support apparatus 100.
The magazine release cutout 134 proximate to the second moveable boss 302 is configured to provides access allowing the magazine release 1404 of the firearm 1300 when the firearm 1300 is coupled to the support plate 102 and the magazine release 1404 of the firearm 1300 is proximate to the top face 112 of the support plate 102.
The top striker holder 138 supports a striker 1500 of the firearm 1300 in a generally vertical position, when the striker 1500 has been removed from the firearm 1300. In addition, the top striker holder 138 is configured and located such that a portion of a curved exterior surface of the top striker holder 138 is juxtaposed with a concave intersection of the barrel 1302 and a firearm trigger guard 1304 when the firearm 1300 is coupled to the firearm support apparatus 100, providing additional horizontal restraint of the firearm 1300. In addition, the height of the top striker holder 138 matches the height of the top legs 116 such that the top striker holder 138 provides additional support and rigidity to the support plate 102 when the bottom face 200 is facing upwards.
In the present embodiment, the top striker holder 138 is configured for the striker of a .45 ACP pistol, but it will be readily apparent to those skilled in the art that the top striker holder 138 may be modified for other makes and models of firearms. The use of the top striker holder 138 is described further below in
The top trigger holder 142 includes the front top trigger wall 1600 and the rear top trigger wall 1602 for demountably coupling a trigger 1800 of the firearm 1300 to the support plate 102, in a generally horizontal position, when the trigger 1800 is removed during disassembly or maintenance. A first trigger hole 210 and a second trigger hole 212 included in the support plate 102 (not shown) are located between the front top trigger wall 1600 and the rear top trigger wall 1602, configured to permit removal of a first trigger pin 1802 and a second trigger pin 1804 from the trigger 1800 when the trigger 1800 is coupled to the firearm support apparatus 100. The top trigger holder 142 and the trigger holes 210, 212 are described further below in
The plurality of cutout perimeter walls 144, edge perimeter walls 148, and honeycomb walls 146 provide additional stiffness and rigidity to the support plate 102. Those skilled in the art will note that in lieu of a thinner support plate 102 including cutout perimeter walls 144, honeycomb walls 146, and edge perimeter walls 148, a thicker support plate 102 would also be suitable. The cutout perimeter walls 144 and honeycomb walls 146 are shorter than the typical wall height where required to provide support for varying surface contours of the firearm 1300.
The magazine edge 106 includes the magazine edge notch 150. The magazine edge notch 150 provides clearance for a trigger bar 1806 when the trigger bar is

The first moveable boss 300 includes the first top cylinder 304, the first bottom cylinder 306, the first bolt 308 and the first nut 310. In the present embodiment, the first top cylinder 304 and the first bottom cylinder 306 are identical, and are described below in
The first top cylinder 304 and the first bottom cylinder 306 each include the bolt hole 512, as described further below in
The first bolt 308 includes the first bolt head 320 and the first bolt shaft 322. In the present embodiment, the first bolt head 320 is hexagonal and configured to snugly fit within the perimeter of a hexagonal cavity 504 of the first top cylinder 304, as shown below in
In a similar manner, the support plate 102 is sandwiched between the second top cylinder 312 and the second bottom cylinder 314 at the second boss cutout 136, using the threaded second bolt 316 and the second nut 318.
Referring again to
The usage of the top cylinder 304, 312 and the bottom cylinder 306, 314 allows for both a means for adjusting the tightness of the moveable boss 300, 302 and for the firearm support apparatus 100 to be used with either the top face 112 upwards with the top cylinders 304, 312 juxtaposed with the firearm 1300, or the bottom face 200 upwards with the bottom cylinders 306, 314 juxtaposed with the firearm 1300.
Referring next to
The first moveable boss 300 and the second moveable boss 302 are shown coupled to the support plate 102. The support plate 102 is shown with the top face 112 facing upwards when the firearm support apparatus 100 is supported by the external support.
As previously described in
After the firearm 1300 is placed on the top face 112, the first moveable boss 300 is then slid to juxtapose the curved side of the first top cylinder 304 of the first moveable boss 300 with a concave portion of the firearm 1300 where a rear portion of a grip meets a back strap 1308. The first bolt 308 is then tightened, frictionally coupling the first moveable boss 300 to the support plate 102. The extent of the first boss cutout 130 allows for sliding adjustments to be made to secure different types and configurations of firearms. The coupling of the first moveable boss 300 to the firearm support apparatus 100 is described further below in
Similarly to the first moveable boss 300, the second moveable boss 302 is coupled to the support plate 102 at the second boss cutout 136 such that the second moveable boss 302 slides across a portion of the support plate 102 when the coupling is loosened, but is frictionally coupled to the support plate 102 when the second bolt 316 is tightened. The second moveable boss 302 has a range of slidable movement limited by the contact of the second bolt shaft 326 with the edge of the second boss cutout 136. The sliding of the second moveable boss 302 allows for the second moveable boss 302 to be slid away from the firearm 1300 along the plane of the support plate 102 when the firearm 1300 is supported by the support plate 102, providing clearance for the firearm 1300 to be placed on the support plate 102. As with the first moveable boss 300, while the second moveable boss 302 is adjustable, the second moveable boss 302 remains coupled to the support plate 102 as a result of the second bolt 316 passing through the second boss cutout 136, preventing misplacement of the second moveable boss 302.

The interior hexagonal wall 502 surrounding the hexagonal cavity 504 of the first top cylinder 304 is configured to snugly fit both the hexagonal first bolt head 320 and the first bolt 308. The plurality of interior vertical ribs 506 connects the cylinder perimeter wall 500 to the hexagonal wall 502, and matches the height of the perimeter wall 500. In the embodiment shown, the first top cylinder 304 includes six interior vertical ribs 506. Each vertical rib 506 is coupled to the hexagonal wall 502 at one end and to the perimeter wall 500 at the other end. The vertical ribs 506 are coupled to the hexagonal wall 502 at the hexagonal wall 502 vertex locations.
The cylinder perimeter wall 500 includes the plurality of outer ridges 508. The outer ridges 508 are vertical indentations in an outer surface of the first top cylinder 304 that result in a corrugation of the outer surface of the first top cylinder 304. In the embodiment shown, the outer ridges 508 extend from a top face 112 of the first top cylinder 304 to approximately 1/16″ from the bottom face 200 of the first top cylinder 304.
The cylinder base 510 of the first top cylinder 304 is disc-shaped and extends to the cylindrical outer surface of the first top cylinder 304. The cylinder base 510 is integrally coupled to the perimeter wall 500, the hexagonal wall 502, and the plurality of interior vertical ribs 506.
The bolt hole 512 is a circular hole in the base 510 and is configured to allow the first bolt shaft 322 to pass through the bolt hole 512 while providing enough surface of the base 510 to couple the bolt head to the base 510. The bolt hole 512 is concentric with the cylinder perimeter wall 500.
Referring again to
The hexagonal wall 502 is shaped so that the interior face of the hexagonal wall 502 snugly fits both the first bolt head 320 and an outer perimeter of the first nut 310. The snug fitting restrains the first bolt head 320 and the first nut 310 from rotating with respect to the first top cylinder 304 or the first bottom cylinder 306 when either first cylinder 304, 306 is rotated, allowing the first moveable boss 300 to be easily loosened or tightened without removing the moveable boss 300 from the support plate 102.
The interior vertical ribs 506 provide additional rigidity to the first top cylinder 304 while decreasing the amount of material used in the first top cylinder 304. Those skilled in the art will note that the number and size of ribs 506 may be altered, or the first top cylinder 304 may be solid except for the hexagonal cavity 504.
The outer ridges 508 provide a gripping surface to assist a user while rotating the first top cylinder 304, and also provide a gripping surface for the frictional coupling of the first top cylinder 304 to the firearm 1300.
The bolt hole 512 provides access for the first bolt shaft 322 to pass through the first top cylinder 304 with the first bolt head 320 coupled to the portion of the base 510 surrounding the cylinder.
It should be noted that while the first moveable boss 300 is described in

Referring next to
As previously described, the first top cylinder 304 is coupled to the first bottom cylinder 306 using the first bolt 308 and the first nut 310. The bottom face 200 of the base 510 of the first top cylinder 304 is juxtaposed with the perimeter wall of the first boss cutout 130 extending outward from the top face 112 of the support plate 102. The first bolt 308 is passed through the bolt hole 512 in the first top cylinder 304 so that the first bolt head 320 is rotationally restrained by the hexagonal wall 502 of the first top cylinder 304, and the first bolt shaft 322 passes through the bolt hole 512 of the first top cylinder 304 and through the first boss cutout 130.
The base bottom face 600 of the first bottom cylinder 306 is juxtaposed with the first boss cutout 130 perimeter wall extending outward from the bottom face 200 of the support plate 102. The first bolt shaft 322 passes through the bolt hole 512 of the first bottom cylinder 306 and extends into hexagonal cavity 504 of the first bottom cylinder 306. To couple the first moveable boss 300 to the support plate 102, the first nut 310 is placed in the hexagonal cavity 504 of the first bottom cylinder 306 such that a hole of the first nut 310 is juxtaposed with the end of the first bolt shaft 322. The first nut 310 is threaded on to the end of the first bolt shaft 322 by holding the first top cylinder 304 motionless and rotating the first bottom cylinder 306, thus threading the first nut 310 onto the first bolt shaft 322 and coupling the first moveable boss 300 to the support plate 102.
Continued rotating of the first bottom cylinder 306 draws the first bottom cylinder 306 closer to the first top cylinder 304 until juxtaposition of the bottom face 200 of each first cylinder 304, 306 with the cutout perimeter walls 144 prevents further rotation and frictionally couples the first moveable boss 300 to the support plate 102. Rotating of the first bottom cylinder 306 in the opposite direction separates the first cylinders 304, 306, allowing for sliding of the first moveable boss 300 relative to the support plate 102. Further rotating of the first bottom cylinder 306 detaches the first nut 310 from the first bolt 308. It should be noted that alternately the first top cylinder 304 may be rotated with respect to the first bottom cylinder 306, or both first cylinders 304, 306 may be rotated simultaneously in opposite directions, to obtain the same result.
The installation, tightening and loosening of the first moveable boss 300 to the support plate 102 applies equally to the second moveable boss 302, utilizing instead the second top cylinder 312, the second bottom cylinder 314, the second bolt 316, and the second nut 318 in lieu of the first top cylinder 304, the first bottom cylinder 306, the first bolt 308 and the first nut 310.
Referring again to
When the first top cylinder 304 and the first bottom cylinder 306 are coupled using the first bolt 308 and the first nut 310, with the first bolt shaft 322 passing through the first boss cutout 130, the first moveable boss 300 may be adjusted to various positions relative to the support plate 102 by sliding the first moveable boss 300 in a direction parallel to the horizontal plane of the support plate 102. The extent of the adjustment is limited by the first bolt 308 being surrounded by the cutout perimeter walls 144 of the first boss cutout 130.
As a result, the first moveable boss 300 may be slidingly moved so that a portion of the outer surface of the first top cylinder 304, or a portion of the outer surface of the first bottom cylinder 306, is juxtaposed with a portion of a firearm 1300, and then tightened to secure the firearm 1300 to the support plate 102, as shown further below in
The adjustment capacity of the first moveable boss 300 also accommodates different models and types of firearms 1300. To remove the firearm 1300 from the block, the first moveable boss 300 is loosened and slid away from the firearm 1300. In the current embodiment, the moveable bosses 300, 302 and the boss cutouts 130, 136 are configured to secure Smith and Wesson Semi-Automatic M&P pistols and Glock Semi-Automatic Pistols, but those skilled in the art will note that the invention may be modified to accommodate additional makes and models of firearms 1300.
