Description
[0001] This application claims the benefit of U.S. Provisional
Patent Application No. 61/395,651, filed May 17, 2010, by applicant
Louie Barletta.
BACKGROUND OF THE INVENTION
[0002] The present invention relates generally to an adaptation to
a firearm that may change its legal classification. Specifically,
an uzi, or any firearm of sufficiently similar properties to that
of an uzi that it may be similarly classified by law, is classified
under an Assault Weapons Ban in the State of California as being in
violation of California Penal Code (PC) 12276, and thus is illegal
to own. More specifically, it is the readily detachable magazine of
an uzi that violates PC 12276.1(a)(1).
[0003] Numerous firearm safety and magazine lock mechanisms are
described in the prior art, such as U.S. Pat. No. 7,752,796 B2
(Ramsey, Sr.), U.S. Pat. No. 7,568,302 B1 (Bubits), U.S. Pat. No.
7,543,403 B1 (Schaefer), U.S. Pat. No. 6,952,895 B1 (Zonshine),
U.S. Pat. No. 6,412,207 B1 (Crye et. al.), U.S. Pat. No. 6,256,919
B1 (Brazeau), and U.S. Pat. No. 4,798,018 (Johansson); however,
none of the prior art teach or imply a suitable method that may be
adapted to prevent the magazine of an uzi from being detached.
[0004] To declassify an uzi under PC 12276, manufacturers and
individuals have provided uzis with a non-detachable magazine by
means of welding or otherwise permanently fixing the magazine catch
mechanism on the lower receiver of an uzi. However, such solutions
are undesired because it is physically impossible to ever detach
the magazine.
[0005] Accordingly, what is desired, and has not heretofore been
developed, is a means of preventing the magazine of an uzi firearm
from being released by pressing the magazine catch mechanism with a
finger, further providing a means of releasing the magazine from
the uzi only by pressing the magazine catch mechanism with a key or
suitable elongated member.
BRIEF SUMMARY OF THE INVENTION
[0006] It is an object of the present invention to provide a means
of preventing the magazine of an uzi firearm from being released by
pressing the magazine catch mechanism with a finger.
[0007] It is an object of the present invention to provide a means
of preventing the magazine of an uzi firearm from being released by
pressing the magazine catch mechanism with a finger that is not
readily or easily circumvented.
[0008] It is an object of the present invention to provide a means
of preventing the magazine of an uzi firearm from being released by
pressing the magazine catch mechanism with a finger that is
inexpensive to manufacture.
[0009] It is an object of the present invention to provide a means
of releasing the magazine of an uzi firearm only by pressing the
magazine catch mechanism with a key or suitable elongated
member.
[0010] It is an object of the present invention to provide a means
of releasing the magazine of an uzi firearm only by pressing the
magazine catch mechanism with a key or suitable elongated member
that is not readily or easily circumvented.
[0011] It is an object of the present invention to provide a means
of releasing the magazine of an uzi firearm only by pressing the
magazine catch mechanism with a key or suitable elongated member
that is inexpensive to manufacture.

DETAILED DESCRIPTION OF THE INVENTION
[0019] Heretofore and henceforth the term `uzi` is used to describe
any firearm of sufficiently similar properties to that of an uzi
that it may be similarly classified by law.
[0020] Heretofore and henceforth the term `key` is used to describe
any generally elongated and sufficiently rigid member capable of
being inserted through the key through hole 12 and capable of
pressing the magazine catch mechanism 20.
[0021] Heretofore and henceforth the term `finger` is used to
describe a human finger of normal or average diameter.
[0022] Heretofore and henceforth the term `diameter` is used to
describe the general length or width of an opening, hole, or object
cross section regardless of the actual shape--circular or
non-circular--of the opening, hole, or object cross section.
[0023] FIG. 1a shows a typical uzi 1 with a standard grip plate 100
attached to the lower receiver of the uzi 1. The magazine 40, which
may hold a repository of ammunition to be fired by the uzi 1, may
be at least partially housed within the lower receiver of the uzi
1. The magazine catch mechanism 20 facilitates the locking of the
magazine 40 in place within the lower receiver of the uzi 1 so that
it will not fall out, cannot be removed, and thus cannot be
reloaded with ammunition. Pressing against the magazine catch
mechanism 20 with a finger in a direction perpendicular to the
exterior face of the magazine catch mechanism 20 may cause the
magazine 40 to be released from within the lower receiver of the
uzi 1, as shown in FIG. 2, and subsequently removed from the lower
receiver of the uzi 1 and potentially reloaded with ammunition.
[0024] As shown in FIG. 3a, FIG. 3b, FIG. 3c, and FIG. 3d, the
standard grip plate 100 comprises an exterior face 150, an interior
face 160, at least one fastener through hole 110 defined
therethrough, and an opening 130. The standard grip plate 100 may
be attached to the uzi 1, with the interior face 160 adjacent to
the lower receiver, by means of a fastener 30 inserted through at
least one fastener through hole 110, such fastener 30 mating with a
fastener receiver element defined on the uzi 1, such as a threaded
or ribbed bore.
[0025] When the standard grip plate 100 is attached to the uzi 1,
the opening 130 is adjacent to the magazine catch mechanism 20,
such opening 130 of sufficient size to permit unobstructed access
to, and normal operation of, the magazine catch mechanism 20 by
means of a finger. Pressing the magazine catch mechanism 20 may
cause the magazine 40 to be released and removed from the uzi 1 and
subsequently reloaded with ammunition.
[0026] FIG. 1b shows a typical uzi 1 with the detachable magazine
lock grip plate 10 attached to the lower receiver of the uzi 1. It
can be seen that the detachable magazine lock grip plate 10
completely encloses the magazine catch mechanism 20, thereby
preventing the magazine 40 from being released by pressing the
magazine catch mechanism 20 with a finger.
[0027] As shown in FIG. 4a, FIG. 4b, FIG. 4c, and FIG. 4d, the
detachable magazine lock grip plate 10 comprises an exterior face
15, an interior face 16, at least one fastener through hole 11
defined therethrough, a cavity 14 defined on and within the
interior face 16, and a key through hole 12 defined therethrough
and adjacent to the cavity 14. The detachable magazine lock grip
plate 10 may be attached to the uzi 1, with the interior face 16
adjacent to the lower receiver, by means of a fastener 30 inserted
through at least one fastener through hole 11, such fastener 30
mating with a fastener receiver element defined on the uzi 1, such
as a threaded or ribbed bore.
[0028] When the detachable magazine lock grip plate 10 is attached
to the uzi 1, the cavity 14 is adjacent to the magazine catch
mechanism 20, such cavity 14 of sufficient volume to permit
unobstructed normal movement or operation of the magazine catch
mechanism 20. However, because the first embodiment of the
detachable magazine lock grip plate 10 completely encloses the
magazine catch mechanism 20, the magazine catch mechanism 20 cannot
be pressed by a finger. To press or otherwise activate the magazine
catch mechanism 20, a key 50 may be inserted through the key
through hole 12, such key through hole 12 having a diameter
substantially smaller than the diameter of a finger. Pressing the
magazine catch mechanism 20 with a key 50 may cause the magazine 40
to be released and removed from the uzi 1 and subsequently reloaded
with ammunition.
[0029] A first alternate embodiment of the detachable magazine lock
grip plate 10 is shown in FIG. 5a, FIG. 5b, FIG. 5c, and FIG. 5d,
which comprises an exterior face 15, an interior face 16, at least
one fastener through hole 11 defined therethrough, and a cavity 14
defined on and within the interior face 16, and a semi-circular key
through hole 17 defined therethrough and adjacent to the cavity 14.
This first alternate embodiment of the detachable magazine lock
grip plate 10 may be attached to the uzi 1, with the interior face
16 adjacent to the lower receiver, by means of a fastener 30
inserted through at least one fastener through hole 11, such
fastener 30 mating with a fastener receiver element defined on the
uzi 1, such as a threaded or ribbed bore.
[0030] When the first alternate embodiment of the detachable
magazine lock grip plate 10 is attached to the uzi 1, the cavity 14
is adjacent to the magazine catch mechanism 20, such cavity 14 of
sufficient volume to permit unobstructed normal movement or
operation of the magazine catch mechanism 20. However, because this
first alternate embodiment of the detachable magazine lock grip
plate 10 completely encloses the magazine catch mechanism 20, the
magazine catch mechanism 20 cannot be pressed by a finger. To press
or otherwise activate the magazine catch mechanism 20, a
semi-circular key 51 may be inserted through the semi-circular key
through hole 17, such semi-circular key through hole 17 shaped to
prevent a finger or flat key 50 from being inserted therethrough.
Pressing the magazine catch mechanism 20 with a semi-circular key
51 may cause the magazine 40 to be released and removed from the
uzi 1 and subsequently reloaded with ammunition.
[0031] A second alternate embodiment of the detachable magazine
lock grip plate 10 is shown in FIG. 6a, FIG. 6b, FIG. 6c, and FIG.
6d, which comprises an exterior face 15, an interior face 16, at
least one fastener through hole 11 defined therethrough, and a
cavity 14 defined on and within the interior face 16. This second
alternate embodiment does not contain a key through hole 12 or a
semi-circular key through hole 17. This second alternate embodiment
of the detachable magazine lock grip plate 10 may be attached to
the uzi 1, with the interior face 16 adjacent to the lower
receiver, by means of a fastener 30 inserted through at least one
fastener through hole 11, such fastener 30 mating with a fastener
receiver element defined on the uzi 1, such as a threaded or ribbed
bore.
[0032] When the second alternate embodiment of the detachable
magazine lock grip plate 10 is attached to the uzi 1, the cavity 14
is adjacent to the magazine catch mechanism 20, such cavity 14 of
sufficient volume to permit unobstructed normal movement or
operation of the magazine catch mechanism 20. However, because the
second alternate embodiment of the detachable magazine lock grip
plate 10 completely encloses the magazine catch mechanism 20, and
because there is no key through hole 12 or semi-circular key
through hole 17, the magazine catch mechanism 20 can neither be
pressed by a finger, a key 50, a semi-circular key 51, or by any
other external means. Therefore, the magazine 40 may only be
released from the uzi 1 by first completely removing the second
alternate embodiment of the detachable magazine lock grip plate 10
from the uzi 1, by removal of the fastener 30 or fasteners 30 that
attach it to the lower receiver of the uzi 1, followed by pressing
of the now-exposed magazine catch mechanism 20.
[0033] Although specific embodiments of the detachable magazine
lock grip plate have been illustrated and described, many
variations or modifications would be apparent that do not depart
from the spirit and scope of the invention, which are defined by
the appended claims.
