MAGAZINE COUPLER
BACKGROUND OF THE INVENTION
1. Field of Invention The present invention relates generally to magazines for use with firearms, and in particular to a magazine coupling device to connect two magazines together.
BACKGROUND OF THE INVENTION
1. Field of Invention The present invention relates generally to magazines for use with firearms, and in particular to a magazine coupling device to connect two magazines together.
2. Description of Related Art Many firearms use a magazine to store and feed ammunition. Magazines are available in a variety of shapes and sizes, with the detachable box magazine being most common. A detachable box magazine can be loaded or unloaded when detached from the corresponding firearm. As necessary, an empty magazine can be detached from the firearm and replaced with another loaded magazine.
A basic box magazine commonly comprises an outer case into which the ammunition is loaded, a feed mechanism, which includes a compression spring with a follower, a floorplate and a cover. Ammunition is loaded into the magazine, above the follower, compressing the spring. As ammunition is used, the spring provides an expansive force between the floorplate and the follower, raising the ammunition within the magazine and into the firearm.
When the ammunition in one magazine has been depleted, the operator may require efficient replacement of the magazine with another loaded magazine, with little delay in operation of the firearm. Typically, the operator carries additional loaded magazines on his person. The extra magazines may be contained within pockets of a bandolier, either around the waist or over the shoulder and across the body, or within a supplementary container. The operator must extract a loaded magazine from its storage location and engage it with the firearm following removal of the spent magazine. The act of removing a fresh magazine from its storage location may cause an undesirable delay in firearm action.
To reduce the delay between extracting the spent magazine and engaging a fully loaded magazine, previous devices have been utilized to couple two magazines together, such that a fully loaded magazine is attached to the engaged magazine and is readily at hand when the engaged magazine is depleted of ammunition. Although there remains a delay in firearm use as one magazine is removed and another engaged, this arrangement eliminates the additional delay caused by extracting a loaded magazine from a storage location, thereby improving firearm efficiency.
Previous attempts have been made to permit two magazines to be connected together. Such attempts, however, have not been satisfactory. In particular, =
some devices utilize a modified base plate with protruding studs and receiving apertures to engage the opposing studs of the coupled magazine. Such arrangements require precise placement of the two magazines to engage the coupling method, and studs can catch and break. Additionally, this method of coupling allows just one arrangement of the magazines, such that the ammunition in one magazine is aligned in the opposite direction to the second magazine, without the option to modify the angle between the two magazines.
Such arrangement may not be optimal for all operators. Examples of such devices may be found in US Patent No. 3,191,332 to Ardolino, for example.
Other devices require the magazine to have a protruding base plate, or to utilize a threaded rod to couple the two magazines. Such designs can be cumbersome to engage, and may easily be damaged by dirt and debris. =
Examples of such designs may be found in US Patent No 4,685,238 to Schoepflin, for example.

DETAILED DESCRIPTION
Referring to Figure 1, a firearm with attached coupled magazines 10 is generally shown at 8. Figure 2 shows a side view of the coupled magazines
-6-10, and Figure 3 shows an alternate configuration of coupled magazines 10.
The alternate configurations of coupled magazines will be described in more detail below. In Figure 1, top magazine 20 is engaged with the firearm 8.
Bottom magazine 22 is not engaged with the firearm 8, but is coupled to top magazine 20, for future use or storage, as will be described in more detail below. Top magazine 20 and bottom magazine 22 may be identical, but are identified separately to differentiate between the engaged top magazine 20 and the disengaged bottom magazine 22.
Figure 4 illustrates an exploded side view of one of the magazines 20. As noted above, bottom magazine 22 may be identical to top magazine 20.
Magazine 20 is comprised of a magazine body 30 having a follower 32, spring 34, spring plate 36 therein and a floorplate 38 secured to a bottom thereof.
The magazine body 30 extends between front and rear ends 60 and 62, respectively, corresponding to the front and rear edges of the ammunition 29 stored therein. The magazine body 30 comprises a box container extending between top and bottom ends 42 and 44, respectively and first and second sides 70 and 72, respectively, as seen on Figure 5, with a cavity 24 therein, as seen on Figure 6.
To assemble the magazine 20, a plurality of ammunition 29, the follower 32, spring 34 and spring plate 36 are inserted in order into the cavity 24 in the magazine body 30 through an opening 31 in the bottom end 44 thereof, compressing spring 34. The floorplate 38, having top and bottom surfaces 92 and 94, respectively, and first and second ends, 93 and 95, respectively, is then attached to the magazine body 30, as will be described in more detail below, to retain the follower 32, spring 34 and spring plate 36 therein. The floorplate 38 has top and bottom planes 202 and 204 corresponding generally to the top and bottom surfaces 92 and 94, respectively, which are separated by a coupler plane angle 206 such as ranging from 0 to 90 degrees, the purpose of which will be further described below.
The alternate configurations of coupled magazines will be described in more detail below. In Figure 1, top magazine 20 is engaged with the firearm 8.
Bottom magazine 22 is not engaged with the firearm 8, but is coupled to top magazine 20, for future use or storage, as will be described in more detail below. Top magazine 20 and bottom magazine 22 may be identical, but are identified separately to differentiate between the engaged top magazine 20 and the disengaged bottom magazine 22.
Figure 4 illustrates an exploded side view of one of the magazines 20. As noted above, bottom magazine 22 may be identical to top magazine 20.
Magazine 20 is comprised of a magazine body 30 having a follower 32, spring 34, spring plate 36 therein and a floorplate 38 secured to a bottom thereof.
The magazine body 30 extends between front and rear ends 60 and 62, respectively, corresponding to the front and rear edges of the ammunition 29 stored therein. The magazine body 30 comprises a box container extending between top and bottom ends 42 and 44, respectively and first and second sides 70 and 72, respectively, as seen on Figure 5, with a cavity 24 therein, as seen on Figure 6.
To assemble the magazine 20, a plurality of ammunition 29, the follower 32, spring 34 and spring plate 36 are inserted in order into the cavity 24 in the magazine body 30 through an opening 31 in the bottom end 44 thereof, compressing spring 34. The floorplate 38, having top and bottom surfaces 92 and 94, respectively, and first and second ends, 93 and 95, respectively, is then attached to the magazine body 30, as will be described in more detail below, to retain the follower 32, spring 34 and spring plate 36 therein. The floorplate 38 has top and bottom planes 202 and 204 corresponding generally to the top and bottom surfaces 92 and 94, respectively, which are separated by a coupler plane angle 206 such as ranging from 0 to 90 degrees, the purpose of which will be further described below.
-7-Turning now to Figure 5, the floorplate 38 has first and second sides 80 and 82, respectively. As illustrated in Figure 5, the follower 32, spring 34 (not shown) and spring plate 36 have been previously inserted into magazine body 30. With a single ammunition 29 in the magazine body 30, the follower 32 is positioned proximate to the top end 42 of the magazine body 30. Spring plate 36 is positioned proximate to the bottom end 44 of the magazine body 30. To retain the assembly together, the floorplate 38 may be secured to the magazine body 30 over the spring plate 36, which will be more fully set out below.
Turning now to Figure 10, the spring plate 36 extends between front and rear ends 60 and 62, respectively, top and bottom 64 and 66, respectively, and top and bottom surfaces 46 and 48, respectively. The spring plate 36 has a length between the front and rear ends 60 and 62 and a width sized to be slidably received within the cavity 24, as illustrated in Figure 6. As illustrated in Figure 10, the spring plate 36 includes a plurality of protrusions extending from the bottom surface 48 thereof. In particular, a front protrusion 52 is located proximate to the front end 60, and a rear protrusion 56 is located proximate to the rear end 62. Furthermore, a central protrusion 54 extending from the bottom surface 48 and is centred between the front and rear protrusions, 52 and 56. The front and rear protrusions, 52 and 56, are generally conical in shape with a rounded tip, and the central protrusion 54 is generally frustoconial in shape, with a curved transition between the central protrusion side 78 and central protrusion end surface 79. The purpose of this curved transition will be described in more detail below.
As best seen on Figures 6 and 7, the length of magazine body 30 at the bottom end 44 extending between front end 60 and rear end 62, may be longer than at the top end 42 as is commonly known. An angled shoulder 100 within magazine body 30 at the front end 60 reduces the length of the cavity 24 of magazine body 30 thereabove. When the spring plate 36 is positioned within the bottom portion of the cavity 24, positioning guides 102 and 104, as best seen on Figure 9, are positioned to fit within the narrower portion of
Turning now to Figure 10, the spring plate 36 extends between front and rear ends 60 and 62, respectively, top and bottom 64 and 66, respectively, and top and bottom surfaces 46 and 48, respectively. The spring plate 36 has a length between the front and rear ends 60 and 62 and a width sized to be slidably received within the cavity 24, as illustrated in Figure 6. As illustrated in Figure 10, the spring plate 36 includes a plurality of protrusions extending from the bottom surface 48 thereof. In particular, a front protrusion 52 is located proximate to the front end 60, and a rear protrusion 56 is located proximate to the rear end 62. Furthermore, a central protrusion 54 extending from the bottom surface 48 and is centred between the front and rear protrusions, 52 and 56. The front and rear protrusions, 52 and 56, are generally conical in shape with a rounded tip, and the central protrusion 54 is generally frustoconial in shape, with a curved transition between the central protrusion side 78 and central protrusion end surface 79. The purpose of this curved transition will be described in more detail below.
As best seen on Figures 6 and 7, the length of magazine body 30 at the bottom end 44 extending between front end 60 and rear end 62, may be longer than at the top end 42 as is commonly known. An angled shoulder 100 within magazine body 30 at the front end 60 reduces the length of the cavity 24 of magazine body 30 thereabove. When the spring plate 36 is positioned within the bottom portion of the cavity 24, positioning guides 102 and 104, as best seen on Figure 9, are positioned to fit within the narrower portion of
-8-cavity 24 above the shoulder 100, whereas a top edge 106 at the front of the spring plate 36 fits within the wider bottom portion of cavity 24, restricting upward movement of the spring plate 36 past the shoulder 100 within the bottom portion of the cavity 24. The spring plate 36 can move upwards within the cavity 24 such that the tips of all protrusions, 52, 54 and 56, can be fully contained within the cavity 24 while the floorplate 38 is being attached to the magazine body 30, as will be described below.
As seen on Figure 5, magazine body 30 has first groove 74 within the first side 70 proximate to the bottom end 44, and second groove 76 within the second side 72 and proximate to the bottom end 44. The two grooves 74 and 76 are aligned with each other and extend the full length of the magazine body 30, from front end 60 to rear end 62, as seen on Figure 4. The purpose of this groove will be described in more detail below.
Figures 5 and 8 best illustrate the top of floorplate 38. Extending upwards from top plane 202 on first and second sides 80 and 82 are first and second upstanding walls 84 and 86, respectively. First upstanding wall 84 has a first inward facing ridge 88 on a distal end thereof, and the second upstanding wall 86 has a second inward facing ridge 90 on a distal end thereof. The two walls with inward facing ridges are equivalently sized, and are mirrored about centreline 200. The first and second inward facing ridges 88 and 90 are positioned such that they can be engaged with first and second grooves 74 and 76 of magazine body 30. First end, middle and second end apertures or bores, 108, 110 and 112, respectively, are positioned along the centreline 200, to correspond to the protrusions on the spring plate 36. As illustrated, the bores 108, 110 and 112 are substantially circular although it will be appreciated that other profiles may be useful as well. In particular, the first end aperture 108 is located proximate to the first end 93, the second end aperture 112 is located proximate to the second end 95 and the middle aperture 110 is located therebetween. First and second end apertures, 108 and 112, are sized and positioned to receive front and rear protrusions, 52 and 56, and middle aperture 110 is sized and positioned to receive central
As seen on Figure 5, magazine body 30 has first groove 74 within the first side 70 proximate to the bottom end 44, and second groove 76 within the second side 72 and proximate to the bottom end 44. The two grooves 74 and 76 are aligned with each other and extend the full length of the magazine body 30, from front end 60 to rear end 62, as seen on Figure 4. The purpose of this groove will be described in more detail below.
Figures 5 and 8 best illustrate the top of floorplate 38. Extending upwards from top plane 202 on first and second sides 80 and 82 are first and second upstanding walls 84 and 86, respectively. First upstanding wall 84 has a first inward facing ridge 88 on a distal end thereof, and the second upstanding wall 86 has a second inward facing ridge 90 on a distal end thereof. The two walls with inward facing ridges are equivalently sized, and are mirrored about centreline 200. The first and second inward facing ridges 88 and 90 are positioned such that they can be engaged with first and second grooves 74 and 76 of magazine body 30. First end, middle and second end apertures or bores, 108, 110 and 112, respectively, are positioned along the centreline 200, to correspond to the protrusions on the spring plate 36. As illustrated, the bores 108, 110 and 112 are substantially circular although it will be appreciated that other profiles may be useful as well. In particular, the first end aperture 108 is located proximate to the first end 93, the second end aperture 112 is located proximate to the second end 95 and the middle aperture 110 is located therebetween. First and second end apertures, 108 and 112, are sized and positioned to receive front and rear protrusions, 52 and 56, and middle aperture 110 is sized and positioned to receive central
-9-protrusion 54 of spring plate 36. Both first and second end apertures, 108 and 112, are sized the same, such that they can each receive either front or rear protrusion, 52 or 56 to permit the floorplate to be secured to the magazine body 30 from either direction.
As illustrated in Figure 8, a first ridge 114 extends along the centreline 200, from the first end aperture 108 to the middle aperture 110. A second ridge 116 extends from the second end aperture 112 to the middle aperture 110. Each of the first and second ridges include tapers down to the first end, middle and second end apertures 108, 110 and 112. It will be appreciated that although ridges are shown in the present embodiment of the invention, the first and second ridges, 114 and 116, could be eliminated and the floorplate 38 could be manufactured such that the material between bottom plane 204 and top plane 202 could be solid, with the first end, middle and second end apertures, 108, 110 and 112, remaining as illustrated, with tapered openings to permit engagement of the front, central and rear protrusions, 52, 54, 56, of the spring plate 36.
As illustrated in Figures 6 and 7, the floorplate 38 can be attached to the magazine body 30 starting from either the front or rear end, 60 or 62. Figure illustrates the floorplate 38 beside the rear end 62, prior to attachment. As set out above, the floorplate 38 can be positioned with either the first end 93 or the second end 95 proximate to the rear end 62 of the magazine body 30. In particular, Figure 6 illustrates the first end 93 proximate to the rear end 62, although the floorplate 38 could be oriented in the opposite direction. To assemble, the first and second inward facing ridges 88 and 90 of floorplate 38 are aligned with the first and second grooves 74 and 76 of the magazine body 30, and the floorplate 38 is slid onto the magazine body 30 in a direction generally indicated at 300, parallel to top plane 202. As the floorplate 38 is slid into place, the three protrusions, 52, 54 and 56 of the spring plate 36 ride on the first and second ridges, 114 and 116 of floorplate 38, thereby compressing the spring 34 and lifting the spring plate 36 within the cavity 24 of the magazine body 30. As the tops of the apertures 108, 110 and 112 are
As illustrated in Figure 8, a first ridge 114 extends along the centreline 200, from the first end aperture 108 to the middle aperture 110. A second ridge 116 extends from the second end aperture 112 to the middle aperture 110. Each of the first and second ridges include tapers down to the first end, middle and second end apertures 108, 110 and 112. It will be appreciated that although ridges are shown in the present embodiment of the invention, the first and second ridges, 114 and 116, could be eliminated and the floorplate 38 could be manufactured such that the material between bottom plane 204 and top plane 202 could be solid, with the first end, middle and second end apertures, 108, 110 and 112, remaining as illustrated, with tapered openings to permit engagement of the front, central and rear protrusions, 52, 54, 56, of the spring plate 36.
As illustrated in Figures 6 and 7, the floorplate 38 can be attached to the magazine body 30 starting from either the front or rear end, 60 or 62. Figure illustrates the floorplate 38 beside the rear end 62, prior to attachment. As set out above, the floorplate 38 can be positioned with either the first end 93 or the second end 95 proximate to the rear end 62 of the magazine body 30. In particular, Figure 6 illustrates the first end 93 proximate to the rear end 62, although the floorplate 38 could be oriented in the opposite direction. To assemble, the first and second inward facing ridges 88 and 90 of floorplate 38 are aligned with the first and second grooves 74 and 76 of the magazine body 30, and the floorplate 38 is slid onto the magazine body 30 in a direction generally indicated at 300, parallel to top plane 202. As the floorplate 38 is slid into place, the three protrusions, 52, 54 and 56 of the spring plate 36 ride on the first and second ridges, 114 and 116 of floorplate 38, thereby compressing the spring 34 and lifting the spring plate 36 within the cavity 24 of the magazine body 30. As the tops of the apertures 108, 110 and 112 are
-10-tapered, and the protrusions 52, 54 and 56 are similarly tapered, the protrusions can engage with the apertures when lateral force is applied along top plane 202 to the floorplate 38 as it is slid into place on the magazine body 30. When all protrusions, 52, 54, 56, are engaged with all apertures, 108, 110, 112, the floorplate 38 is correctly aligned and will remain in place until vertical force is applied to the central protrusion end surface 79 to disengage protrusions 52, 54 and 56, and additional lateral force is applied along the top plane 202, which will allow for removal of the floorplate 38. Figure 7 illustrates the floorplate 38 fully engaged with the magazine body 30 and the spring plate 36. It will be appreciated that once fully loaded with ammunition that the follower 32 will be located lower in the magazine body 30, thereby compressing the spring 34 to apply a greater force to the spring plate 36, thereby resisting removal of the floorplate.
Turning now to Figures 11 and 12, Figure 11 illustrates one option and Figure 12 illustrates a second option of the present embodiment of the invention.
Floorplate 38 has bottom surface 94 on plane 204 including a plurality of protrusions for locking two floorplates together. Centreline 200 separates first and second sides 80 and 82, and centreline 207 separates first and second ends, 93 and 95. The bottom of floorplate 38 is divided into four quadrants:
first quadrant 208, second quadrant 210, third quadrant 212 and fourth quadrant 214, as illustrated in Figure 12. The protrusions from the first and second quadrants 208 and 210 are rotated 180 degrees about the intersection of the centrelines 200 and 207, such that the protrusions from the first and third quadrants 208 and 212 are similar, and the protrusions in the second and fourth quadrants 210 and 214 are similar.
In first quadrant 208, a first outer ledge 120 is spaced apart from the bottom surface 94 with a gap thereunder facing outward toward first side 80. Second outer ledge 122 in third quadrant 212 is identical to the first outer ledge 120 as rotated 180 degrees about the intersection of centrelines 200 and 207 similarly facing outward toward the second side 82. In second quadrant 210, a first outer catch 124 is spaced apart from the bottom surface 94 with a gap
Turning now to Figures 11 and 12, Figure 11 illustrates one option and Figure 12 illustrates a second option of the present embodiment of the invention.
Floorplate 38 has bottom surface 94 on plane 204 including a plurality of protrusions for locking two floorplates together. Centreline 200 separates first and second sides 80 and 82, and centreline 207 separates first and second ends, 93 and 95. The bottom of floorplate 38 is divided into four quadrants:
first quadrant 208, second quadrant 210, third quadrant 212 and fourth quadrant 214, as illustrated in Figure 12. The protrusions from the first and second quadrants 208 and 210 are rotated 180 degrees about the intersection of the centrelines 200 and 207, such that the protrusions from the first and third quadrants 208 and 212 are similar, and the protrusions in the second and fourth quadrants 210 and 214 are similar.
In first quadrant 208, a first outer ledge 120 is spaced apart from the bottom surface 94 with a gap thereunder facing outward toward first side 80. Second outer ledge 122 in third quadrant 212 is identical to the first outer ledge 120 as rotated 180 degrees about the intersection of centrelines 200 and 207 similarly facing outward toward the second side 82. In second quadrant 210, a first outer catch 124 is spaced apart from the bottom surface 94 with a gap
-11-therebetween facing inward and is sized and positioned to mate with first or second outer ledges 120 and 122 such that each ledge or catch is located within the opposite gap. In fourth quadrant 214, a second outer catch 126 is spaced apart from the bottom surface 94 with a gap therebetween facing toward the centreline 200 and is sized and positioned to mate with first or second outer ledges 120 and 122 such that each ledge or catch is located within the opposite gap. In second quadrant 210, a first inner ledge 130 is spaced apart from the bottom surface 94 with a gap therebetween facing outward toward the first side 80. A second inner ledge 132 in fourth quadrant 214 similarly is spaced apart from the bottom surface 94 with a gap therebetween facing outward toward the second side 82. In first quadrant 208, a first inner catch 134 is spaced apart from the bottom surface 94 with a gap therebetween facing toward the centreline 200 and is sized and positioned to mate with first or second inner ledges 130 and 132 such that each ledge or catch is located within the opposite gap. In third quadrant 212, a second inner catch 136 is sized and positioned to mate with first or second inner ledges 130 and 132 such that each ledge or catch is located within the opposite gap.
All ledges and catches are generally formed as an upstanding wall from the bottom surface 94 with a ridge at the distal end sized to fit within the gap below the ridge of the corresponding ledge or catch when two floorplates are connected bottom to bottom, as set out below.
As seen in Figure 12, an optional first block 140 extends from the bottom surface 94 in second quadrant 210 while an optional second block 142 extends from the bottom surface 94 in fourth quadrant 214. A first stop 144 extends from the bottom surface 94 in first quadrant 208 and is sized and positioned to meet with either first or second block 140 and 142 when two floorplates 38 are coupled together. A second stop 146 extends from the bottom surface 94 in third quadrant 212 and is sized and positioned to meet with either first or second block 140 and 142 when two floorplates 38 are coupled together. It may be appreciated that some of the protrusions as illustrated in the present embodiment of the invention are optional, and other configurations may be useful, as well.

A first stop 144 extends from the bottom surface 94 in first quadrant 208 and is sized and positioned to meet with either first or second block 140 and 142 when two floorplates 38 are coupled together. A second stop 146 extends from the bottom surface 94 in third quadrant 212 and is sized and positioned to meet with either first or second block 140 and 142 when two floorplates 38 are coupled together. It may be appreciated that some of the protrusions as illustrated in the present embodiment of the invention are optional, and other configurations may be useful, as well.
-12-As illustrated in Figure 4, coupler plane angle 206 separates top plane 202 from bottom plane 204 of floorplate 38. When coupler plane angle 206 is greater than 0 degrees, the distance between top surface 92 and bottom surface 94 is smaller at first end 93 than at second end 95 so as to angularly orient two magazine bodies 30 relative to each other. The coupler plane angle 206 may be selected to be any angle as desired by a user, such as, by non-limiting example, between 0 and 90 degrees.
Figures 2 and 3 illustrate the two possible configurations to couple two floorplates, 38a and 38b together. Top floorplate 38a and bottom floorplate 38b may be identical, but are identified separately to differentiate between the floorplate 38a of the engaged top magazine 20 and the bottom floorplate 38b of the disengaged bottom magazine 22. In Figure 2, the two floorplates 38a and 38b are coupled such that the first ends 93 are aligned together, and the second ends 95 are aligned together. The result of this alignment is that the coupled magazines, 20 and 22, essentially form a curved outer profile. In Figure 3, the two floorplates 38a and 38b are coupled such that that the top floorplate 38a first end 93 is aligned with the bottom floorplate 38b second end 95, and the top floorplate 38a second end 95 is aligned with the bottom floorplate 38b first end 93. The result of the alignment shown in Figure 3 is that the coupled magazines, 20 and 22, essentially form a straight outer profile. The benefit of having the ability to create alternate profiles is user preference. As set out above, a magazine body 30 may be connected onto a floorplate 38 from either direction, permitting the user to select the relative orientation of the coupled magazines 20 and 22. Figure 2 illustrates both magazine bodies 30 oriented such that both front ends 60 are aligned with first ends 93 of the floorplates 38, although it may be appreciated that both rear ends 62 of the magazine bodies 30 may be aligned with first ends 93 of the floorplates 38, or one front end 60 of one magazine body 30 may be aligned with the first end 93 of its floorplate 38, while the other front end 60 of the second magazine body 30 may be aligned with the second end 95 of its floorplate 38, for a total of three possible configurations with the first floorplate

Top floorplate 38a and bottom floorplate 38b may be identical, but are identified separately to differentiate between the floorplate 38a of the engaged top magazine 20 and the bottom floorplate 38b of the disengaged bottom magazine 22. In Figure 2, the two floorplates 38a and 38b are coupled such that the first ends 93 are aligned together, and the second ends 95 are aligned together. The result of this alignment is that the coupled magazines, 20 and 22, essentially form a curved outer profile. In Figure 3, the two floorplates 38a and 38b are coupled such that that the top floorplate 38a first end 93 is aligned with the bottom floorplate 38b second end 95, and the top floorplate 38a second end 95 is aligned with the bottom floorplate 38b first end 93. The result of the alignment shown in Figure 3 is that the coupled magazines, 20 and 22, essentially form a straight outer profile. The benefit of having the ability to create alternate profiles is user preference. As set out above, a magazine body 30 may be connected onto a floorplate 38 from either direction, permitting the user to select the relative orientation of the coupled magazines 20 and 22. Figure 2 illustrates both magazine bodies 30 oriented such that both front ends 60 are aligned with first ends 93 of the floorplates 38, although it may be appreciated that both rear ends 62 of the magazine bodies 30 may be aligned with first ends 93 of the floorplates 38, or one front end 60 of one magazine body 30 may be aligned with the first end 93 of its floorplate 38, while the other front end 60 of the second magazine body 30 may be aligned with the second end 95 of its floorplate 38, for a total of three possible configurations with the first floorplate
-13-coupling configuration illustrated in Figure 2. Similarly, Figure 3 is illustrated with both front ends 60 of the magazine bodies 30 aligned with both first ends 93 of the floorplates 38, but they may be assembled in other configurations, as well, for a total of three possible configurations with the second floorplate coupling configuration illustrated in Figure 3.
To couple two floorplates 38a and 38b together, the bottom surfaces are aligned to face each other at an offset angle, as shown in Figure 13, with the centres of both floorplates 38a and 38b aligned. The two floorplates 38a and 38b are then rotated together in the direction generally indicated at 302.
Figure 14 illustrates two floorplates 38a and 38b locked in the engaged position, and best shows the engagement of ledges and catches described above. To disengage the floorplates 38a and 38b, rotate in the opposite direction and pull apart.
Various methods and materials may be used to manufacture the magazine body 30, follower 32, spring plate 36 and floorplate 38, such as by way of non-limiting example injection mould, casting or cold punch.
While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims.
