Description
FIELD

The present disclosure relates generally to clamping assemblies and loader assemblies. In particular, the present disclosure relates to clamping assemblies and loader assemblies that facilitate the loading of cartridges into a firearm magazine.


BACKGROUND

Many repeating firearms, such as pistols, submachine guns, assault rifles, and others, utilize magazines (often referred to as a clip) to store and feed cartridges (or bullets) into the firearm. A popular type of magazine in modern rifles and handguns is the box magazine, which stores cartridges in either a singular column or double column (also referred to as a zig-zag stack). Typically, box magazines are detachable and function to move the cartridges stored within the magazine into a position where they can be loaded into a barrel chamber by the action of the firearm. For example, box magazines are often slidably received within a slot in the firearm, usually below the action but occasionally to the side or on top. Typical box magazines are self-contained mechanisms capable of being loaded and unloaded while detached from the host firearm.


Generally, cartridges are loaded into the box magazine one at a time and gradually compress a spring. The spring produces a force that guides the cartridges towards an opening in the magazine, in order to be fed into the chamber of the firearm. The force supplied by the spring can make loading cartridges into magazine increasingly difficult, especially when the magazine is approaching its carrying capacity and the spring force is at a near maximum. For example, operators having weaker hands or arthritis may not be able to load a magazine whatsoever. As such, an apparatus for loading a firearm magazine is desired in the art. In particular, an apparatus that reduces the difficulty of loading a firearm magazine is desired in the art.


BRIEF DESCRIPTION

Aspects and advantages of the clamping assemblies and loader assemblies in accordance with the present disclosure will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the technology.


In accordance with one embodiment, a clamping assembly for clutching a firearm magazine during loading of a cartridge into the firearm magazine is provided. The clamping assembly includes a main frame having a back stop portion, a first side portion, and a second side portion; a first side plate; and a second side plate. The clamping assembly further includes a first connection plate disposed between the first side plate and the first side portion of the main frame and pivotably coupled to both the main frame and the first side plate. The clamping assembly further includes a second connection plate disposed between the second side plate and second side portion of the main frame and pivotably coupled to both the main frame and the second side plate.

Referring now to the drawings, FIGS. 1 through 3 illustrate various views of a loader assembly 100 in accordance with embodiments of the present disclosure. Particularly, FIG. 1 illustrates a perspective view of the loader assembly 100. FIG. 2 illustrates a cross-sectional view of the loader assembly 100. Additionally, FIG. 3 illustrates a cross-sectional view of the loader assembly 100 coupled to a firearm magazine 200. The loader assembly 100 may facilitate the loading of a cartridge 202 (or bullets) into the firearm magazine 200, such as a pistol magazine, rifle magazine, or other magazine. For example, the loader assembly 100 may advantageously provide additional leverage for a user to easily load the cartridges 202 into the firearm magazine 200 with minimal effort by the user.


As shown in FIGS. 2 and 3, the loader assembly 100 may define a Cartesian (or rectangular) coordinate system having a longitudinal direction L, a vertical direction V, and a transverse direction (not shown, but extending into and out of the page in FIGS. 2 and 3).


In exemplary embodiments, as shown, the loader assembly 100 may include a cartridge member 102, a plunger member 104, and a clamping assembly 106. The clamping assembly 106 may be removably couplable to the cartridge member 102, and the plunger member 104 may be slidably couplable with the cartridge member 102.


The clamping assembly 106 may include a main frame 108, a first side plate 110, a second side plate 112, a first connection plate 114, and a second connection plate 116. The main frame 108 may include a top portion 118, a back stop portion 120, a first side portion 122, and a second side portion 124. The back stop portion 120 may extend (e.g., generally vertically) from the top portion 118 of the main frame 108 to a terminal end 125 (FIG. 2). The first side portion 122 and the second side portion 124 may be spaced apart from one another and each extend generally perpendicularly from the back stop portion 120. The top portion 118 of the main frame 108 may extend from back stop portion 120 at an angle relative to the vertical direction V and/or the longitudinal direction L. The side portions 122, 124 may extend (e.g., generally vertically and longitudinally) from the top portion 118. The main frame 108 may define a cavity 126 collectively by the top portion 118, the back stop portion 120, the first side portion 122, and the second side portion 124.


As shown in FIG. 3, the firearm magazine 200 may include a top wall 208, a back wall 204, front wall 206, and side walls (not shown) extending between the back wall 204 and the front wall 206. In operation, as shown in FIG. 3, the firearm magazine 200 may be inserted into the cavity 126 of the main frame 108 until the back wall 204 of the firearm magazine 200 is be forced against the back stop portion 120, and the top wall 208 is forced against the top portion 118, in order to align the firearm magazine 200 within the clamping assembly 106. Additionally, the side portions 122, 124 may each be positioned adjacent to (and/or in contact with) the side walls of the firearm magazine 200 (not shown).


Referring still to FIGS. 1 through 3, the cartridge member 102 may be removably couplable with the clamping assembly 106. For example, the cartridge member 102 include a tube body 128 and a connection block 134 extending from the tube body 128. The tube body 128 may extend from a connection end 130 to a free end 132. The connection end 130 of the tube cartridge member 128 may be positioned within the cavity 126 of the main frame 108. The free end 132 may be disconnected from any other components. The connection block 134 may extend from the tube cartridge member 128 proximate the connection end 130 (i.e., closer to the connection end 130 than the free end 132). In the embodiment shown, the connection block 134 may be generally shaped as a rectangular prism (which advantageously prevents rotation of the clamping assembly 106 relative to the tube cartridge member 128); however, it should be appreciated that other shapes are within the scope and spirit of the present disclosure. Additionally, as shown best in FIG. 2, the main frame 108 may define a slot 136 having a shape that corresponds with an exterior shape of the connection block 134, such that the connection block 134 may be slidably coupled to the main frame 108 via the slot 136. In other words, the connection block 134 may be slidably couplable to the main frame 108 via the slot 136 defined in the main frame 108.


The tube body 128 of the cartridge member 102 may define a cartridge slot 142 that is sized to receive a plurality of cartridges 202 (FIG. 3). The cartridge slot 142 may extend from an inlet 144 at the free end 132 to an outlet 146 at the connection end 130. In many embodiments, the tube body 128 may include an inlet segment 148 and a guide segment 153. The inlet segment 148 may extend from the free end 132 to the guide segment 153, and the guide segment 153 may extend from the inlet segment 148 to the connection end 130. The inlet segment 148 may be shaped as a hollow half cylinder, which allows for cartridges 202 to be easily inserted into the guide segment 153. In other words, the inlet segment 148 includes an open top 149 sized to receive the cartridges 202. The guide segment 153 may have a semi-closed top 151 that prevents the cartridges 202 from falling out of the cartridge slot 142 while still allowing for slidable movement of the plunger member 104.


The plunger member 104 may be movably coupled to the cartridge member 102. In many embodiments, the plunger member 104 may include a press portion 138 and a slider portion 140. The slider portion 140 may extend generally perpendicularly from the press portion 138. The slider portion 140 may be insertable into (and movable within) the cartridge slot 142. In this way, a user may apply a force to the press portion 138 to slide the slider portion 140 within the cartridge slot 142. During operation, the slider portion 140 may contact a cartridge 202, and a user may apply a force to the press portion 138 to load cartridges 202 into the firearm magazine 200.



FIGS. 4 and 5 each illustrate the clamping assembly 106, which may be included in the loader assembly 100 discussed above with reference to FIGS. 1 through 3. The clamping assembly 106 may be configured to clutch a firearm magazine 200 during the loading of a cartridge 202 into the firearm magazine 200 (FIG. 3). The clamping assembly 106 may include the main frame 108, the first side plate 110, the second side plate 112, the first connection plate 114, and a second connection plate 116.


The first connection plate 114 may be disposed between the first side plate 110 and the first side portion 122 of the main frame 108. Further, the first connection plate 114 may pivotably couple to both the first side plate 110 and the first side portion 122 of the main frame 108. For example, the first connection plate 114 may be pivotably coupled to the to the first side portion 122 of the main frame 108 on a first side of the first connection plate 114, and the first connection plate 114 may be pivotably coupled to the first side plate 110 on a second side of the first connection plate 114. Similarly, the second connection plate 116 may be disposed between the second side plate 112 and the second side portion 124 of the main frame 108. Further, the second connection plate 116 may pivotably couple to both the second side plate 112 and the second side portion 124 of the main frame 108. For example, the second connection plate 116 may be pivotably coupled to the to the second side portion 124 of the main frame 108 on a first side of the second connection plate 116, and the second connection plate 116 may be pivotably coupled to the second side plate 112 on a second side of the second connection plate 116.


Still referring to FIGS. 4 and 5, a first ball and socket joint 162 may be defined between the first connection plate 114 and the first side plate 110. Particularly, the first ball and socket joint 162 may be one of a plurality of first ball and socket joints 162 spaced apart from one another, with each first ball and socket joint 162 pivotably coupling the first connection plate 114 to the first side plate 110. Additionally, a second ball and socket joint 164 may be defined between the first connection plate 114 and the main frame 108. The second ball and socket joint 164 may be one of a plurality of second ball and socket joints 164 spaced apart from one another, with each second ball and socket joint 164 pivotably coupling the first connection plate 114 to the main frame 108 (e.g., to the first side portion 122 of the main frame 108). Each of the first ball and socket joints 162 may be aligned with one another vertically and spaced apart longitudinally. Likewise, each of the second ball and socket joints 164 may be aligned with one another vertically and spaced apart longitudinally. Alignment of the first ball and socket joints (162) and the second ball and socket joints (164) may be vertical or staggered longitudinally.


Similarly, a third ball and socket joint 166 may be defined between the second connection plate 116 and the second side plate 112. Particularly, the third ball and socket joint 166 may be one of a plurality of third ball and socket joints 166 spaced apart from one another, with each third ball and socket joint 166 pivotably coupling the second connection plate 116 to the second side plate 112. Additionally, a fourth ball and socket joint 168 may be defined between the second connection plate 116 and the main frame 108. The fourth ball and socket joint 168 may be one of a plurality of fourth ball and socket joints 168 spaced apart from one another, with each fourth ball and socket joint 168 pivotably coupling the second connection plate 116 to the main frame 108 (e.g., to the second side portion 124 of the main frame 108). Each of the third ball and socket joints 166 may be aligned with one another vertically and spaced apart longitudinally. Likewise, each of the fourth ball and socket joints 168 may be aligned with one another vertically and spaced apart longitudinally. Alignment of the third ball and socket joints (166) and the fourth ball and socket joints (168) may be vertical or staggered longitudinally.



FIG. 6 illustrates an enlarged exploded view of the connection assembly 106 in accordance with exemplary aspects of the present disclosure. As shown, the connection assembly 106 may include a main frame 108 having a side portion 150 (which may be representative of either or both the first side portion 122 and/or the second side portion 124 discussed above with reference to FIGS. 1-5). Additionally, the connection assembly 106 may include a side plate 152 and a connection plate 154. The side plate 152 may be representative of either (or both) of the first side plate 112 and/or the second side plate 114 discussed above with reference to FIGS. 1-5. Similarly, the connection plate 154 may be representative of either (or both) the first connection plate 114 and/or the second connection plate 116 discussed above with reference to FIGS. 1-5.


As shown in FIG. 6, the connection plate 154 may include a main body 156, a first coupling feature 158, and a second coupling feature 160. The first coupling feature 158 and the second coupling feature 160 may each extend from the main body 156 in opposite directions. The first coupling feature 158 may be pivotably (and removably) couplable to the side portion 150, and the second coupling feature 160 may be pivotably (and removably) couplable to the side plate 152.


The first coupling feature 158 and the second coupling feature 160 may each be at least one of a ball 170 extending from the main body 156 or a socket defined in the main body 156. The ball and socket joint as described may also be non-spherical (ie. of a geometry suitable to allow rotation about a common axis). As a non-limiting example, the ball and socket connections along a common axis can be replaced with a piano hinge along the common axis. That is, in the illustrated embodiment, the first coupling feature 158 and the second coupling feature 160 are each balls 170 that extend from the main body 156, and the corresponding sockets 172, 174 are defined in the main frame 108 and the side plate 152. However, in other embodiments (not shown), the ball and socket arrangement may be reversed. In such an arrangement, the balls may extend from the main frame 108 and the side plate 152, and the sockets may be defined in the main frame 156.


As shown in FIG. 6, each of the balls 170 may define as slot 176, which may partition the ball 170 into a first portion 178 and a second portion 180 spaced apart from one another such that a gap is defined therebetween. The slot 176 may advantageously facilitate the removable coupling of the connection plate 154 to the sockets 172 in the main frame and the sockets 174 in the side plate 152.


During operation, a user may adjust a gap (e.g., a transverse gap) between the side plates 110, 112 and the connection plates 114, 116 by pivoting the side plates 110, 112 and the connection plates 114, 116 relative to each other and relative to the main frame. This advantageously allows for flexibility in the size firearm magazine to be clamped (or clutched) by the clamping assembly.


Referring now to FIGS. 7 through 9, a loader assembly 300 is illustrated in accordance with embodiments of the present disclosure. Particularly, FIG. 7 illustrates a perspective view of the loader assembly 300. FIG. 8 illustrates an exploded view of the loader assembly 300. FIG. 9 illustrates a cross-sectional view of the loader assembly 300. The loader assembly 300 may facilitate the loading of a cartridge (or bullets) into the firearm magazine, such as a pistol magazine, rifle magazine, or other magazine. For example, the loader assembly 300 may advantageously provide additional leverage for a user to easily load the cartridges into the firearm magazine with minimal effort by the user.


As shown in FIGS. 9, the loader assembly 300 may define a Cartesian (or rectangular) coordinate system having a longitudinal direction L, a vertical direction V, and a transverse direction (not shown, but extending into and out of the page in FIG. 9).


In exemplary embodiments, as shown, the loader assembly 300 may include a cartridge member 302, a plunger member 304, and a clamping assembly 306. The clamping assembly 306 may be removably couplable to the cartridge member 302, and the plunger member 304 may be slidably couplable with the cartridge member 302.


The clamping assembly 306 may include a main frame 308, a first side plate 310, a second side plate 312, a first connection plate 314, and a second connection plate 316. The main frame 308 may include a top portion 318, a back stop portion 320, a first side portion 322, a second side portion 324, a first wing portion 317, and a second wing portion 319. The first wing portion 317 may extend from the first side portion 322 away from the first connection plate 314, and the second wing portion 319 may extend from the second side portion 324 away from the second connection plate 316. The wing portions 317, 319 may define a plurality of openings that advantageously reduce weight while maintaining structural integrity.


The back stop portion 320 may extend (e.g., generally vertically) from the top portion 318 of the main frame 308 to a terminal end 323 (FIG. 9). The first side portion 322 and the second side portion 324 may be spaced apart from one another and each extend generally perpendicularly from the back stop portion 320. The top portion 318 of the main frame 308 may extend from back stop portion 320 and the side portions 322, 324, and the top portion 318 may partially define an opening 325 into which the cartridge member 302 may be inserted. The side portions 322, 324 may extend (e.g., generally vertically and longitudinally) from the top portion 318.


During operation, the firearm magazine 200 may be inserted into the main frame 308 until a back wall of the firearm magazine is forced against the back stop portion 320. Subsequently, the user may adjust a gap (e.g., a transverse gap) between the side plates 310, 312 and the connection plates 314, 316 by pivoting the side plates 310, 312 and the connection plates 314, 316 relative to each other and relative to the main frame 308. This advantageously allows for flexibility in the size firearm magazine to be clamped (or clutched) by the clamping assembly 306.


Referring still to FIGS. 7 through 9, the cartridge member 302 may be removably couplable with the clamping assembly 306. For example, the cartridge member 302 include a body 328 and a connection block 334 extending from the body 326. The body 326 may extend from a connection end 330 to a free end 332. The connection end 330 of the cartridge member 302 may be positioned within the main frame 308. The free end 332 may be disconnected from any other components. The connection block 334 may extend from the body 328 to the connection end 330. Additionally, as shown best in FIG. 8, the main frame 308 may define an opening 325 having a shape that corresponds with an exterior shape of the connection block 334, such that the connection block 334 may be slidably coupled to the main frame 308 via the opening 325.


The body 328 of the cartridge member 302 may include a first side bar 341 a second side bar 343, and a web 345 extending between the first side bar 341 and the second side bar 343. A cartridge slot 342 that is sized to receive a plurality of cartridges may be defined by the first side bar 341, the second side bar 343, and the web 345. The cartridge slot 342 may extend from an inlet at the free end 332 to an outlet at the connection end 330.


The plunger member 304 may be movably coupleable to the cartridge member 302. In many embodiments, the plunger member 304 may include a press portion 338 and a slider portion 340. The press portion 338 may include an annular body 339 that defines a cavity 337. The slider portion 340 may extend generally perpendicularly from the annular body 339 of the press portion 338 into the cavity 337. The slider portion 340 may be insertable into (and movable within) the cartridge slot 342. For example, the annular body 339 may surround the cartridge member 302, and the slider portion 340 may extend into the slot 342 to restrict movement of the plunger member 304 along the slot 342. In this way, a user may apply a force to the press portion 338 to slide the slider portion 340 within the cartridge slot 342. During operation, the slider portion 340 may contact a cartridge, and a user may apply a force to the press portion 338 to move the plunger member 304 within the slot 342 and load cartridges into the firearm magazine.



FIGS. 10 and 11 each illustrate the clamping assembly 306, which may be included in the loader assembly 300 discussed above with reference to FIGS. 6 through 9. The clamping assembly 306 may be configured to clutch a firearm magazine during the loading of a cartridge into the firearm magazine. The clamping assembly 306 may include the main frame 308, the first side plate 310, the second side plate 312, the first connection plate 314, and a second connection plate 316.


The first connection plate 314 may be disposed between the first side plate 310 and the first side portion 322 of the main frame 308. Further, the first connection plate 314 may pivotably couple to both the first side plate 310 and the first side portion 322 of the main frame 308.
