Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation of U.S. patent
application Ser. No. 15/059,350, filed Mar. 3, 2016y, which is a
continuation-in-part of U.S. patent application Ser. No.
14/945,536, filed Nov. 19, 2015, which are incorporated herein by
reference.
FIELD OF THE INVENTION
[0002] The present invention relates to firearms. More
particularly, the present invention relates to a safety magazine
for various firearms.
BACKGROUND OF THE INVENTION
[0003] In recent years, there has been an increase in the number of
accidental, negligent or unauthorized discharge from various
firearms, and particularly handguns. Such incidents typically occur
when the trigger of the firearm is deliberately pulled for a
purpose other than shooting, such as dry-fire practice,
demonstration or function testing, but the ammunition is
unintentionally left in the chamber. Unintentionally leaving a
firearm loaded is more likely to occur when the individual handling
the gun is poorly trained, and perhaps also with
removable-magazine-fed firearms (as the magazine may be removed,
giving an unloaded appearance even when a round remains chambered).
Since most handguns are designed such that the magazine constantly
remains inside, thus keeping the handgun constantly loaded, such
accidental or otherwise undesired or unauthorized discharge is more
likely to occur.
[0004] A second common cause of negligent discharges is placement
by the gun-handler of his/her finger on the trigger before deciding
to shoot. With the finger so positioned, many activities may cause
the finger to compress the trigger unintentionally. For example, if
one attempts to holster the firearm with finger on trigger, the
holster edge might drive the finger onto the trigger, and discharge
is likely.
[0005] Accidental discharges not involving a trigger-pull can also
occur if the firearm is mechanically unsound: due to poor
maintenance, abuse or the use of defective ammunition in the gun,
may all lead to breakage.
[0006] Furthermore, recently there has been a sharp increase in
misuse of firearms with unauthorized users firing (for fun or by
accident), and particularly youngsters using their parents'
firearms. Such incidents cause many injuries (and sometimes
fatalities) since there are no means to prevent other people from
using a gun of an authorized user.
[0007] It would, therefore, be advantageous to provide safety means
for firearms so as to prevent unintentional and/or unauthorized
firing.
[0008] An object of the present invention is to provide a safety
magazine for a firearm.
[0009] A further object of the present invention is to provide a
method for blocking a firearm and preventing accidental discharge.
Further objects of the present invention will be apparent as the
description proceeds.

DETAILED DESCRIPTION OF THE INVENTION
[0073] In the following detailed description, numerous specific
details are set forth in order to provide a thorough understanding
of embodiments of the invention. However, it will be understood by
those of ordinary skill in the art that the embodiments of the
invention may be practiced without these specific details. In other
instances, well-known methods, procedures, and components have not
been described in detail so as not to obscure the embodiments of
the invention.
[0074] Reference is now made to FIGS. 1A-1B, which illustrate a
safety magazine, generally designated 10a, according to a preferred
embodiment of the present invention. FIG. 1A illustrates a frontal
perspective view of a safety magazine 10a, and FIG. 1B illustrates
a back perspective view of safety magazine 10.
[0075] Safety magazine 10 comprises a top cover 11 having a
structure compatible with commercially available magazines for
firearms, for instance having a shape corresponding to and adapted
to be inserted into a magazine housing of, for example, a
Beretta.RTM. 6-bullet handgun. Safety magazine 10 further comprises
a bottom cover 12 that at least partially covers the safety
mechanism, further described hereinafter. Optionally, top cover 11
has a top portion 15 that is configured to couple with the magazine
housing in a compatible firearm. It is appreciated that a top
locking element (or latch) 33 is designed to be capable of
protruding from an opening 13 in top cover 11, whereby the
operation of top locking element 33 is configured to allow locking
safety magazine 10 to the magazine housing when locking element 33
protrudes from the magazine 10a, further described herein
after.
[0076] Reference is now made to FIGS. 1C-1D, which illustrate a
back perspective view of top cover 11 of safety magazine 10 and a
cross-sectional view of safety magazine 10 (respectively),
according to a preferred embodiment of the present invention. It
should be noted that the shape and dimensions of top cover 11
correspond to the shape and dimensions of a regular magazine
(respectively), such that with the bottom elements the difference
from the commercially available magazines may be seen.
[0077] Reference is now made to FIGS. 2A-2B, which illustrate back
and frontal perspective views (respectively) of the safety magazine
with top cover 11 removed, generally designated 20a, according to a
preferred embodiment of the present invention. With top cover 11
removed, safety magazine 20 may further comprise a first and second
corresponding internal covers 21a, 21b that are configured to
protect the mechanical elements (for the safety mechanism) within,
while having a dedicated space 22 for accommodation of bullets in
the magazine. Thus, safety magazine 20 may simultaneously provide
standard operation of a magazine and also provide the safety
mechanism, further described hereinafter. When safety magazine 20
is enabled (i.e. in an unlocked mode), the firearm may be
immediately operated.
[0078] Reference is now made to FIGS. 3A-3B, which illustrate the
safety mechanism with top cover 11 removed, generally designated
30a, according to a preferred embodiment of the present invention.
FIG. 3A illustrates a back perspective view of the safety magazine
with first internal cover 21a removed, and FIG. 3B illustrates a
frontal perspective view of the safety magazine with second
internal cover 21b also removed.
[0079] The safety mechanism may include a power storage unit (e.g.,
a battery) 31, a top locking element (or latch) 33 capable of
locking onto the magazine housing once coupled, and a cam 32. The
power storage (e.g., a battery) 31 is configured to provide power
for the safety mechanism, so as to allow operation of the
mechanical elements. Optionally, power storage 31 may be further
connected to a safety control element 35 that is embedded into
bottom cover 12, so as to provide power to control element 35.
Thus, the user may use control element 35 in order to control the
safety magazine. For example, the user may switch between locked
and unlocked modes (e.g., by pressing a button) of safety magazine
10a, using control element 35. According to some embodiments,
control element 35 may be configured to enable operation of the
safety magazine only by authorized user(s). For example, control
element may comprise identity (ID) recognition unit, e.g., finger
print reader (not shown), and storage of ID data (not shown) for
storing ID data of authorized users.
[0080] The cam 32 is a rotatable piece (typically in a mechanical
linkage) which is adapted to convert a rotary movement into a
reciprocating movement. It may be a part of a rotating wheel (e.g.,
a simple tooth) or a shaft that strikes a lever (making contact
with the cam) or a follower at one or more points on its circular
path Cam 32 is rotatable about an axis coinciding with the center
of a wheel, further described hereinafter.
[0081] It is appreciated that bottom portion 36 of top locking
element 33 is adjacent to cam 32 and acts as a lever once cam 32
the bottom portion 36 during rotation. Therefore, when a locked
mode is selected for safety magazine cam 32 may rotate (with
electrical power from power storage 31), and thus contact bottom
portion 36 such that top locking element 33 protrudes from safety
magazine cover 11 and thereby engages the magazine housing of the
firearm and locks thereon.
[0082] In order to unlock the locked magazine, the user may choose
an unlocked mode (e.g., using control element 35) and thus move cam
32 so as to retract top locking element 33 into the magazine
housing. It is appreciated that other elements may also be involved
in the locking mechanism. For example, a positioning rod 37 may
keep top locking element 33 on track while moving between the two
states: inner state in unlocked mode and an outer state when top
locking element 33 protrudes from the magazine and engages the
magazine housing.
[0083] In some embodiments, the safety magazine further comprises a
pivoted lever 38 that may be configured to sense whether the safety
magazine is inserted into the magazine housing, wherein pivoted
lever 38 may provide indication whether the magazine has been
inserted into the magazine housing. For example, pivoted lever 38
may press (or release) a micro switch as the sensing means during
engagement with the magazine housing. Accordingly, pivoted lever 38
enables (or disables) the controlled features of control element 35
once the safety magazine is inserted into (or removed from) the
magazine housing.
[0084] Reference is now made to FIGS. 4A-4B, which illustrate the
cam 32, according to a preferred embodiment of the present
invention. FIG. 4A illustrates an exploded partial view of the
mechanism of the safety magazine with cam 32 at the center, and
FIG. 4B illustrates a perspective view of cam 32.
[0085] The cam 32 is mechanically engaged and positioned coaxially
with cam wheel 41, and may further have a cam tooth 42 that is
configured to engage bottom portion 36 (for instance as shown in
FIG. 3B) of locking element 33. By rotation of cam 32, the tooth 42
engages locking element 33, such that the rotational movement of
wheel 41 is converted into reciprocating movement, for example of
locking element 33.
[0086] Reference is now made to FIGS. 5A-5B, which illustrate the
safety magazine 10 inserted into a compatible firearm, generally
designated 50a, according to a preferred embodiment of the present
invention. FIG. 5A illustrates a perspective view of safety
magazine 10 inserted into a compatible firearm 50a, and FIG. 5B
illustrates a cross-sectional view of the same.
[0087] It should be noted that safety magazine 10 may be operated
both as a regular magazine, storing bullets at dedicated space 22,
such that firearm 50 can be used in the regular fashion, as well as
be operated as a safety magazine that prevents unwanted (or
unauthorized) use of firearm 50a, when in locked mode.
[0088] In some embodiments, safety magazine 10 is provided in a
locked state (e.g. initially locked by the user) such that, once
safety magazine 10 is inserted into firearm 50a, the safety
magazine 10 is locked to the magazine housing (inside firearm 50)
until an authorized user with a dedicated key removes the lock. For
example, the user may use a physical key (such as an electronic
chip configured for the particular user) in order to unlock the
safety magazine 10.
[0089] In some embodiments, safety magazine 10 is provided with a
physical barrier at top portion 15 (for instance as shown in FIGS.
1A-1B) that may block or otherwise prevent operation of the firearm
even if a bullet is positioned near the barrel, thereby providing
safety.
[0090] In some embodiments, safety magazine 10 may be provided with
a biometric identification unit embedded into the bottom cover such
that safety magazine 10 may be setup to identify a predetermined
list of authorized users, and thereby preventing unauthorized users
from using the firearm. Optionally, safety magazine 10 is also
provided with a mechanical override (e.g., a physical key) to
override the biometric ID unit when faulty or when the power
storage runs out.
[0091] In some embodiments, the locking mechanism may further
comprise a communication unit capable of receiving wireless data
(e.g., via Wi-Fi, Bluetooth, GPS, or cellular networks). The
communication unit may therefore allow a user to set conditions for
the safety magazine to become unlocked. For example, once the
safety magazine detects data that it is inside an authorized area
(for instance from GPS data), then the locking is removed and the
firearm may be used.
[0092] Alternatively, a dedicated signal may be wirelessly received
by the safety magazine such that a user may select that in a
particular time the locking is removed, no matter who operates the
firearm. For example, a training officer at the police academy may
wirelessly remove the locking from multiple firearms that are
scheduled for practice.
[0093] In some embodiments, locking element 33 may also lock the
trigger bar, an internal component of the firearm, so as to prevent
discharge. Optionally, locking element 33 may disconnect the
trigger from the firing pin and thereby rendering the firearm
useless.
[0094] According to some embodiments, the safety mechanism may
further allow locking the trigger of the firearm so as to prevent
movement of the trigger to cause a discharge, as further described
hereinafter. Referring now to FIGS. 6A-10B, these figures show some
embodiments of the safety mechanism capable of locking the trigger
of the firearm.
[0095] Reference is now made to FIGS. 6A-6B, which show a discharge
blocking device, generally designated 100a, according to some
embodiments of the present invention. FIG. 6A illustrates a frontal
perspective view (with respect to the shooting direction of the
firearm) of a discharge blocking device 100a, and FIG. 6B
illustrates a back perspective view of the discharge blocking
device 100.
[0096] It is appreciated that discharge blocking device 100 (as a
safety magazine) according to the invention is adapted to allow a
user, operating a firearm, to block the discharge by having the
safety mechanism (within the device) in a locked mode, such that
the discharge may be enabled only according to the selection by the
user with the safety mechanism. Therefore, in addition to the
existing safety selector on the firearm, discharge blocking device
100 may provide further means for controlling the firing mode of
the firearm (i.e., locked or unlocked mode), further described
hereinafter.
[0097] The discharge blocking device 100 may comprise a cover 110
having a structure that is compatible with some commercially
available magazines for firearms, for instance having a shape and
dimensions corresponding to and adapted to be inserted into a
magazine housing of, for example, a Glock.RTM. handgun. Discharge
blocking device 100 may further comprise a base 120 that at least
partially covers a safety mechanism that is configured to block the
discharge, further described hereinafter. Optionally, base 120 may
have a shape that is larger in diameter than cover 110a, such that
easy gripping (of base 120) by a user operating the firearm may be
allowed for insertion into and removal from the firearm. It is
therefore appreciated that only with the base 120a, the difference
from commercially available magazines may be observed, when the
safety magazine is inserted into a firearm.
[0098] In some embodiments, cover 110 may have a top segment 170
that is configured to couple with the magazine housing in a
compatible firearm (not shown in FIGS. 6A-6B). Top segment 170 has
an opening for insertion of cartridges therein (e.g., in a single
column or staggered), such that the cartridge that is last inserted
partially protrudes through top segment 170 in order to engage the
firearm upon coupling with the magazine housing. Thus, operation
similar to regular magazines for firearms may be enabled as
discharge blocking device 100 provides accommodation of cartridges,
and also engagement of these cartridges with the corresponding
firearm upon coupling, as further described hereinafter.
[0099] It is appreciated that a locking element (or latch) 140a,
accommodated within discharge blocking device 100a, may be
configured to be capable of protruding from a first window 130 in
cover 110. Furthermore, the operation of locking element 140 may be
configured to allow locking discharge blocking device 100 to the
magazine housing (of the corresponding firearm) when locking
element 140 protrudes from discharge blocking device 100 and
additionally lock the trigger of the firearm so as to block the
discharge, as further described hereinafter. It should be noted
that when discharge blocking device 100 is enabled (i.e., in an
unlocked mode), the firearm may be immediately operated.
[0100] In some non-limiting embodiments, cover 110 may further
comprise a recess 180 that corresponds in shape to an external
magazine catch 480 (shown in FIGS. 10A-10B) in order to allow
locking the position of discharge blocking device 100 within the
magazine housing once the external magazine catch is inserted
thereto. Thus, cover 110 may provide features similar to
commercially available firearm magazines, as well as enhanced
features for blocking discharge upon the selection of the user.
[0101] According to some embodiments, at least one locking switch
may control the locking of discharge blocking device 100. In some
embodiments, discharge blocking device 100 may further comprise a
positioning lever 160 that is initially in an "open" state and
configured to allow detection of discharge blocking device 100
accommodated within the magazine housing. Positioning lever 160 may
be configured to be capable of protruding from a second window 150
in cover 110a, such that upon insertion into the magazine housing
of a firearm, positioning lever 160 may engage the inner wall of
the magazine housing. Upon detection of accommodation within the
magazine housing, positioning lever 160 may switch to a "closed"
state. It is appreciated that positioning lever 160 may provide a
first locking mechanism, that may be configured to disable the
operation of the firearm unless in "closed" state. Optionally,
positioning lever 160 may be coupled to a micro-switch that is
capable of electrically detecting change between "open" and
"closed" states, as further described hereinafter.
[0102] In some embodiments, positioning lever 160 maybe operably
coupled to locking element 140a, wherein the coupling may be
electrical or alternatively mechanical. Upon switching to a
"closed" state (i.e., detection of discharge blocking device 100
within the magazine housing) by positioning lever 160a, locking
element 140 may be automatically operated to move to a "locked"
mode and block the trigger of the firearm so as to block any
discharge until the user switches to "unlocked" mode, as further
described hereinafter. It should be noted that, initially,
positioning lever 160 is in an "open" state and locking element 140
is in "unlocked" mode, such that upon engagement with the magazine
housing positioning lever 160 switches to "closed" state and
thereby locking element 140 moves to a "locked" mode. Thus,
discharge blocking device 100 may automatically switch to "locked"
mode and prevent discharge upon engagement with the magazine
housing.
[0103] According to some embodiments, discharge blocking device 100
may further comprise a user identification segment 121. User
identification segment 121 may be operably coupled to the locking
mechanism within discharge blocking device 100 and thereby coupled
to locking element 140 so as to disable the blocking, i.e. switch
to "unlocked" mode upon identification of the user. User
identification segment 121 may comprise biometric user
identification (e.g. fingerprint identification), password
identification with a dedicated user interface, or any other
identification means (for example buttons to be pressed by the
user). Optionally, user identification segment 121 may further
comprise storage of ID data (not shown) for storing ID data of
authorized users.
[0104] In some embodiments, discharge blocking device 100 may
further comprise at least one indicator 123 that is configured to
indicate the locking mode of discharge blocking device 100a, e.g.,
"locked", "unlocked", "error", etc. Optionally, the user may
control indicator 123 in order to change the mode of discharge
blocking device 100a, for instance pressing a button indicated
"SAFE" in order to switch the device to a "locked" mode, or
pressing a button indicated "FIRE" in order to switch the device to
an "unlocked" mode. It should be noted that user identification
segment 121 and indicator 123 may be electrically coupled to the
locking mechanism so as to allow control of the locking mode of
discharge blocking device 100.
[0105] Reference is now made to FIGS. 6C-6D, which show a frontal
perspective view of a cover 110 of discharge blocking device 100
and a cross-sectional frontal view of discharge blocking device 100
(respectively), wherein the cross-section is carried out parallel
to user identification segment 121, according to some embodiments
of the present invention. It should be noted that discharge
blocking device 100 may comprise a space 190 dedicated for
accommodation of the cartridges (e.g., in a single column) as in a
commercially available magazine. Thus, both locking mechanism and
space 190 for accommodation of the cartridges may be covered by
cover 110.
[0106] In some embodiments, the structure of cover 110 corresponds
to a commercially available magazine capable of accommodating
cartridges in a staggered column, such that a different number of
cartridges may be accommodated within discharge blocking device 100
while an additional discharge blocking safety mechanism is
provided.
[0107] According to some embodiments, locking element 140 may be
pivoted about a pivot rod 145 from an "unlocked" mode to a "locked"
mode when locking element 140 protrudes from cover 110. Optionally,
pivot rod 145 may be embedded as a portion of an internal segment
covering the locking mechanism, as further described hereinafter
(for instance as shown in FIG. 8A).
[0108] Reference is now made to FIGS. 7A-7B, which illustrate
frontal and back perspective views (respectively) of the discharge
blocking device with the cover removed, generally designated 200a,
according to some embodiments of the present invention. It should
be noted that, with cover 110 removed, discharge blocking device
200 may further comprise a first and second corresponding internal
segments 210a, 210b that are configured to be adjoined so as to
cover and protect the mechanical and electrical elements (of the
locking mechanism) within.
[0109] It is appreciated that the base 120 may comprise additional
elements for changing the locking mode of discharge blocking device
100a, as further described hereinafter.
[0110] Reference is now made to FIGS. 8A-8B, which show the safety
mechanism within the internal segments with the cover removed,
according to some embodiments of the present invention. FIG. 8A
illustrates a frontal perspective view of the discharge blocking
device with first internal segment 210a removed, and FIG. 8B
illustrates a frontal perspective view of the discharge blocking
device with second internal segment 210b removed. It is appreciated
that the locking (or safety) mechanism housed inside first and
second internal segments 210a, 210b comprises locking element 140
that is capable of blocking the trigger of the compatible firearm
once coupled.
[0111] In case that the discharge blocking device, such as device
100a, is in a locked mode (for instance as shown in FIGS. 8A-8B),
the user may use for example user identification segment 121 to
unlock the device (or other identification options). Thus, locking
element 140 moves from a "locked" mode (i.e., protruding to block
the trigger of a firearm) to an "unlocked" mode. During this
movement, locking element 140 retracts inwardly into cover 110
until locking element 140 engages a back surface 240 such that
locking element 140 no longer protrudes from the discharge blocking
device, i.e., no longer protrudes from first window 130 (for
instance as shown in FIG. 6A). In the opposite case, the user may
control user identification segment 121 to lock the device, or by
inserting the device into magazine housing thereby activating
positioning lever 160. Specifically, moving locking element 140 to
protrude from the discharge blocking device so as to engage the
magazine housing of the firearm and block any discharge.
[0112] It is appreciated that, similar to the safety magazine
described in FIGS. 1A-4A, the locking mechanism of discharge
blocking device may also comprise a cam 232 with similar function
wherein rotational movement is converted into reciprocating
movement. Particularly, movement of cam 232 may engage panel 242 of
locking element 140 so as to move locking element 140 from a
"locked" mode to "unlocked" mode (or vice versa).
[0113] In some embodiments, the control of the movement of locking
element 140 by the user may be carried out mechanically (e.g., with
a dedicated key) or alternatively carried out electrically (e.g.,
with a dedicated switch), as further described hereinafter.
[0114] In some non-limiting embodiments, the safety mechanism may
further comprise a power storage unit 280a, e.g. a battery, (for
instance, as shown in FIG. 8C) that is configured to provide power
for the safety mechanism, so as to allow operation of the
mechanical elements. Optionally, a battery status indicator may
also be provided with the indicators 123, for instance as shown in
FIG. 6B.
[0115] It is appreciated that, in order for locking mode indication
on user identification segment 121, at least one switch may provide
such indication, for instance with an electrical signal. A first
switch 261 may be operably coupled to positioning lever 160 and
provide an indication to user identification segment 121 regarding
the state of discharge blocking device being inside a magazine
housing (i.e., in "open" or "closed states). Specifically, movement
of positioning lever 160 may engage first switch 261 when
accommodated within a magazine housing since positioning lever 160
is pushed into the device due to engagement with the walls of the
magazine housing.
[0116] A second switch 262 may be operably coupled to panel 242 and
provide an indication to user identification segment 121 regarding
the state of discharge blocking device being in "locked" or
"unlocked" modes. Specifically, movement of panel 242 may engage
second switch 262 when in "locked" mode (as shown in FIGS. 8A-8B)
due to locking element 140 protruding and blocking the trigger of
the firearm, thereby causing panel 242 to move backward towards
user identification segment 121 and to engage second switch
262.
[0117] A third switch 263 may be operably coupled to body of
locking element 140 and provide an indication to user
identification segment 121 regarding the state of discharge
blocking device being in "locked" or "unlocked" modes.
Specifically, movement of locking element 140 may engage third
switch 263 when in "unlocked" mode due to locking element 140
engaging back surface 240a, thereby causing locking element 140 to
move backward towards user identification segment 121 and to engage
third switch 263. It should be noted that, in a "locked" mode,
second switch 262 may provide indication due to engagement with
panel 242, and, in the opposite case, in an "unlocked" mode, third
switch 263 may provide indication due to engagement with back
surface 240a, whereby there is no indication between "locked" and
"unlocked" modes since the second and third switches 262,263 are
not engaged.
[0118] It is appreciated that, upon insertion into a magazine
housing, discharge blocking device may become automatically in a
"closed" state with positioning lever 160 engaging first switch 261
and thereby moving the device into a "locked" mode, with locking
element 140 protruding and blocking the trigger of the firearm. In
some embodiments, an electrical signal from first switch 261 may
initiate movement of cam 232 to engage panel 242 and thereby move
locking element 140 to protrude from the device. Alternatively,
movement of positioning lever 160 mechanically moves cam 232 to
engage panel 242.
[0119] It should be noted that user identification segment 121 may
provide indication of "locked" or "unlocked" mode due to
corresponding signals from second and third switches 262, 263.
Optionally, user identification segment 121 may also provide
indication of proper accommodation within the magazine housing with
a corresponding signal from first switch 261.
[0120] It is appreciated that the indication provided with second
and third switches may improve reliability of the safety mechanism,
as well as preventing stopping of locking element movement mid-way,
between "locked" and "unlocked" modes.
[0121] Reference is now made to FIG. 8C, which illustrates an
exploded view of the safety mechanism within the discharge blocking
device with the internal segments removed, according to some
embodiments of the present invention. In some embodiments, a
central controller (not shown) may control the operation of
discharge blocking device. Specifically, such a controller may
control user identification segment 121 switching between "locked"
and "unlocked" modes.
[0122] Reference is now made to FIGS. 9A-9C, which show additional
means for user identification with the discharge blocking device,
according to some embodiments of the present invention. FIG. 9A
illustrates a perspective view of a physical key 310 and a media
device 320. FIG. 9B illustrates a bottom perspective view of the
physical key 310 and media device 320 inserted into the base 120 of
the discharge blocking device. FIG. 9C illustrates a
cross-sectional view of discharge blocking device 100a, wherein the
cross-section is parallel to locking element 140. It should be
noted that other identification methods may also be possible, for
instance radio- frequency identification (RFID),
near-field-communication (NFC), etc.
[0123] According to some embodiments, in addition to the user
identification segment 121, discharge blocking device may further
be configured to allow coupling with other identification devices,
for instance in case that user identification segment 121 has a
malfunction or when the power storage runs out. A unique physical
key 310 may be provided to the user to be inserted into a dedicated
slot 312 within base 120 so as to allow manually moving to an
"unlocked" device. In some embodiments, insertion of key 310 into
slot 312 may allow engaging key 310 with cam 232, such that manual
rotation of key 310 therein (by the user) may consequently rotate
cam 232 and thereby move locking element to an "unlocked" mode.
[0124] In some embodiments, a media device 320 (e.g., USB flash
drive, or PC) may be provided to the user, comprising unique
information, that may unlock the discharge blocking device upon
insertion of media device 320 therein. Optionally, such media
device 320 may allow connection to a computerized device (e.g., PC
or smartphone) in order to allow management of authorized users as
well as performing maintenance.
[0125] Reference is now made to FIGS. 10A-10B, which illustrate the
discharge blocking device 100 inserted into a compatible firearm,
generally designated 400a, according to some embodiments of the
present invention. FIG. 10A illustrates a perspective view of
discharge blocking device 100 inserted into a compatible firearm
400a, and FIG. 10B illustrates a cross-sectional view of the
same.
[0126] It should be noted that discharge blocking device 100 may be
operated both as a regular magazine, storing cartridges at
dedicated space 190a, such that firearm 400 can be used in the
regular fashion, as well as be operated as a discharge blocking
device that prevents unwanted (or unauthorized) use of firearm
400a, when in locked mode.
[0127] It is appreciated that, in a locked mode (as shown in FIG.
10B), locking element 140 protrudes from the discharge blocking
device 100 to approach close to trigger 440 of firearm 400. Thus,
the user cannot squeeze trigger 440 to discharge firearm 400 (in a
locked mode) since locking element 140 prevents any backward
movement of trigger 440. In order to allow discharge, the user may
change the state of discharge blocking device 100 from "locked" to
"unlocked", for example by using the user identification segment
such that locking element 140 moves backwards and no longer
protrudes through the discharge blocking device 100a, and then
trigger 440 may be operated to discharge firearm 400.
[0128] In some embodiments, in addition to blocking the trigger of
the firearm, locking element 140 may also prevent removal of the
discharge blocking device 100 from the magazine housing.
[0129] It should be noted that, in contrast to the safety magazine
that is capable of locking onto the magazine housing as described
in FIGS. 1A-4A, discharge blocking device 100 has a locking element
that is directed to the opposite direction, i.e., towards the
barrel of the firearm, in order to allow blocking the trigger of
the firearm with the locking element.
[0130] In some embodiments, discharge blocking device 100 is
provided with a physical barrier at top segment that may block or
otherwise prevent operation of the firearm even if a cartridge is
positioned near the barrel, thereby providing extra safety.
[0131] In some embodiments, the locking mechanism may further
comprise a communication unit capable of sending and receiving
wireless data (e.g., via Wi-Fi, Bluetooth, GPS, or cellular
networks). The communication unit may therefore allow a user to set
conditions for the discharge blocking device to become unlocked.
For example, once the discharge blocking device detects data that
it is inside an authorized area (for instance from GPS data), then
the locking is removed and the firearm may be used.
[0132] Alternatively, a dedicated signal may be wirelessly received
by the discharge blocking device such that a user may select that
in a particular time the locking is removed, no matter who operates
the firearm. For example, a training officer at the police academy
may wirelessly remove the locking from multiple firearms that are
scheduled for practice.
[0133] While certain features of the invention have been
illustrated and described herein, many modifications,
substitutions, changes, and equivalents may occur to those skilled
in the art. It is, therefore, to be understood that the appended
claims are intended to cover all such modifications and changes as
fall within the true spirit of the invention.
[0134] Various embodiments have been presented. Each of these
embodiments may of course include features from other embodiments
presented, and embodiments not specifically described may include
various features described herein.
