[0001] The present application is a non-provisional patent
application of U.S. Provisional Patent Application No. 61/178,265
filed on May 14, 2009.
BACKGROUND
[0002] Pistols known in the art require the user to move the strong
hand thumb to depress the button to release the magazine from the
pistol, which increases time required for reloading the pistol for
further use. Accordingly, there is a need for a magazine release
that allows the user to keep the strong hand thumb in place and
depress the magazine release with less movement of the strong hand
thumb, therefore decreasing the reloading time for further use.

DETAILED DESCRIPTION
[0028] A magazine release assembly 100 for use with a pistol 300 is
disclosed. In examples, the pistol 300 is large-frame,
medium-frame, compact or sub-compact. Embodiments of the pistol are
shown in FIGS. 5, 7-9, and 13. In other embodiments the magazine
release assembly 100 is configured for use on any gun having a
magazine 200 inserted through a handle cavity 336. The magazine
release assembly 100 includes a pin 110, a magazine release arm
120, and a magazine catch 130. The magazine release assembly 100
may be manufactured from a polymer such as high strength polymer,
metal, stainless steel, or aluminum. The magazine release assembly
100 is configured for use with a magazine 200 such as the one shown
in FIG. 4. In an embodiment, the magazine 200 has a cavity 220 that
is configured to house up to six shells 400, although the magazine
cavity 220 may be configured to hold more than six shells 400. In
the embodiment shown in FIG. 4, the magazine 200 has an extended
bottom 240 to facilitate a better grip. However, in an other
embodiment, the magazine 200 has a substantially flat bottom. See
FIG. 10. The magazine 200 can be manufactured from polymer or the
like. Optionally, the magazine 200 is manufactured from a
translucent polymer.
[0029] As shown in FIGS. 2, 3, and 12 the magazine release assembly
100 includes a pin 110 configured to be positioned through an end
of a pistol trigger guard 320. In use, the pin 110 is positioned
along the width 335 of the handle second wall 334 in a direction
perpendicular to the longitudinal axis 337. A magazine release arm
120 is pivotally mounted to the pin 110. The magazine release arm
120 is configured to be positioned lateral to the trigger guard 320
of the pistol when the magazine release assembly 100 is assembled
on a pistol 300. Optionally, two magazine release arms 120 are
pivotally mounted to the pin 110 to make the magazine release
assembly 100 ambidextrous.
[0030] A magazine catch 130 is pivotally mounted to the pin 110.
See FIGS. 1, 12. The magazine catch 130 is configured to be
positioned between the second wall 334 of the pistol handle 330 and
a wall 233 of the magazine 200 inserted into the cavity 336 of the
pistol handle 330 in use, as shown in FIGS. 5-8. The magazine 200
has a notch 231 on wall 233, as shown in FIG. 4. The magazine catch
130 has a ledge 131 which is configured to engage the notch 231
when the magazine 200 is inserted into the handle cavity 336. As
shown in FIGS. 2B and 3B, when the magazine release arm 120 is
pivoted to an engaged position, the ledge 131 is engaged with the
notch 231 to secure the magazine 200 in the handle cavity 336. The
ledge 131 pivots away from the notch 231 to release the magazine
200 from the handle cavity 336 when the magazine release arm 120 is
pivoted to a disengaged position, as shown in FIGS. 2C and 3C.
[0031] A first embodiment of the magazine release assembly 100 is
shown in FIGS. 1, 2 and 12A. The magazine catch 130 includes a
spring 132 that contacts the second wall 334 of the handle 330 when
the magazine release assembly 100 is assembled on the pistol 300.
In the FIGS., the spring 132 is conical, but spring 132 may be any
shape or configuration. In use, the spring 132 is in a partially
compressed state when the magazine release arm 120 is pivoted to
the engaged position (FIGS. 2B, 5A) and is further compressed when
the magazine release arm 120 is pivoted to the disengaged position
(FIGS. 2C, 5B). When the magazine release arm 120 is pivoted to the
disengaged position, the magazine catch 130 pivots away from the
magazine 200 and the ledge 131 disengages from the notch 231,
thereby releasing the magazine 200 from the handle cavity 336.
[0032] In another embodiment shown in FIGS. 3 and 12B, the magazine
catch 130 includes a member 134 that is bent to form a springable
clip having first and second regions 135, 136 that substantially
align. Ledge 131 is on an end of the first region 135. Second
region 136 contacts the second wall 334 of the handle 330 when the
magazine release assembly 100 is assembled on the pistol 300. In an
example, magazine catch 130 is metal, such as sheet metal. In use,
the second region 136 of the magazine catch 130 is in a partially
compressed state when the magazine release arm 120 is pivoted to
the engaged position (FIG. 3B) and is further compressed when the
magazine release arm 120 is pivoted to the disengaged position
(FIG. 3C). When the magazine release arm 120 is pivoted to the
disengaged position, the magazine catch 130 pivots away from the
magazine 200 and the ledge 131 disengages from the notch 231,
thereby releasing the magazine 200 from the handle cavity 336.
[0033] Optionally, magazine catch 130 includes a protrusion 138
that mates with a pocket on the magazine release arm 120 as shown
in FIGS. 2A, 3A. In an embodiment, the protrusion 138 is the
negative shape of the pocket. Protrusion 138 provides a grip that
helps to prevent slippage of the magazine catch 130 on the pin
110.
[0034] An exploded view of the pistol 300 in combination with the
magazine release assembly 100 and magazine 200 is shown in FIG. 10.
The various components of the pistol are assembled using a variety
of fasteners 301 and function through a variety of springs 341 as
shown generally in the FIGS., and particularly in FIGS. 10 and 11.
The pistol 300 includes a body 310, a barrel 350, and a trigger
325. The body 310 includes a handle 330 and a trigger guard 320. As
shown in FIGS. 6 and 14, the handle 330 has first and second walls
331, 334. The handle 330 has a cavity 336 that defines a
longitudinal axis 337. The cavity 336 is configured for accepting a
magazine 200 through an opening 333 in the first wall 331 of the
handle 330. The second wall 334 defines a width 335 of the handle
330. Optionally, the handle 330 includes a grip 338. The body 310
also includes a trigger guard 320 that has an end 322 positioned
adjacent to the second wall 334 of the handle 330.
[0035] A slide 340 such as those shown in FIGS. 10 and 11 is
detachably connected to the body 310 for sliding along the upper
portion 312 of the body 310 under a resistance provided by a spring
341, such as a spring assembly. The extractor 342 is secured to the
slide 340 by a roll pin 343. The slide 340 moves rearward and trips
the extractor 342 to pull a shell 400 out of the barrel 350 through
the ejection port 344 after firing. Optionally, the slide 340
includes a removable rear sight such as the sight 370 shown in FIG.
11. Optionally, the sight 370 is a tritium sight. Optionally, the
body 310 includes an accessory rail 380 such as the one shown in
FIG. 13 for mounting accessory items such as laser sights, lighting
devices, and the like to the body 310.
[0036] The pistol 300 also includes a threaded barrel 350
configured to engage a frame 360 that mounts to the body 310. The
barrel 350 receives shells 400 from the magazine 200 and fires
bullets. Optionally, the barrel 350 includes an extended accessory
barrel 352 as shown in FIG. 5A for connecting accessory items to
the barrel 350.
[0037] The trigger 325 on the pistol 300 releases a hammer 326 to
strike the rear of a firing pin 328 that strikes a shell 400 in the
barrel 350 to eject the bullet therefrom. The hammer spring 327
provides the tension to the hammer 326. In an embodiment, the
firing pin 328 has a solid surface (FIG. 10). In another
embodiment, the firing pin 328 is fluted (FIG. 11). The flutes 329
on the firing pin 328 help to prevent the pistol 300 from
hydra-locking by providing an outlet through which internal fluids
drain away from the firing pin 328.
[0038] While the foregoing has been set forth in considerable
detail, it is to be understood that the drawings, detailed
embodiments, and examples are presented for elucidation and not
limitation. Design variations, especially in matters of shape,
size, and arrangements of parts, may be made but are within the
principles of the invention. Those skilled in the art will realize
that such changes or modifications of the invention or combinations
of elements, variations, equivalents, or improvements therein are
still within the scope of the invention as defined in the appended
claims.
