Description




FIELD OF THE INVENTION




This invention relates to weapon safes, and more particularly to weapon containers which are locked in a closed configuration by a concealed, gravity-actuated locking assembly that remains locked until the container is placed in an accelerated, positive gravity environment.




SUMMARY




The present invention provides a weapon container for mounting in a vehicle, such as, for example, an aircraft, that may be subject to a positive accelerated gravity environment. The weapon container has a container body defining an interior cavity therein and a top lid that is selectively moved between an open position and a closed position respective to the container body by a container opening assembly. A lock assembly is also provided for movement between a first, locked, position and a second, unlocked, position upon application of an accelerated gravity condition of a predetermined level. In use, the lock assembly prevents movement of the container opening assembly when the lock assembly is in the first position and allows movement of the container opening assembly when the lock assembly is in the second position.




In one embodiment, the lock assembly comprises a mounting plate, a locking member, a lever member, and a knuckle assembly. If used, the mounting plate is affixed to a portion of an interior surface of the interior cavity. The mounting plate has a first mounting pin that extends away from the plate and a second mounting pin spaced from the first mounting pin that also extends away from the plate. The locking member has a first end, an opposed second end, and a longitudinal axis L. At least a portion of the first end of the locking member is in selective operable contact with a portion of the container opening assembly. In use, the locking member moves along the longitudinal axis L between an extended position and a collapsed position.




The lever member has a distal end, an opposed proximal end, an upper surface and a longitudinal axis W. The lever member also defines a bore near the proximal end of the lever member that receives the first mounting pin to pivotally connect the lever member to the first mounting pin of the mounting plate. The distal end of the lever member has a weight attached thereto. The lever member also has an actuation arm that extends away from the proximal end and above the upper surface of the lever member. An end portion of the lever member may bend inward toward the distal end of the lever member as it extends away. In use, the lever member moves rotationally about the first mounting pin upon the application of the predetermined level of the accelerated gravity condition.




The knuckle assembly has a mounting member, a first member, and a second member. The mounting member has a first mounting end, an opposed second mounting end, and a third mounting end that is intermediate the first and second mounting ends. The first mounting pin is connected to the first mounting end and the second mounting pin is connected to the second mounting end so that the mounting member is fixed relative to the mounting plate. The first member is pivotally connected to the second member to form a first joint. One end of the first member is pivotally connected to a portion of the second end of the locking bar member to form a second joint and one end of the second bar member is pivotally connected to the third mounting end of the mounting member to form a third joint. The respective second and third joints are substantially co-axial with respect to the longitudinal axis L of the locking bar assembly.




In use, the lock assembly moves between the first, locked, position and the second, unlocked, position upon application of the accelerated gravity condition of the predetermined level. The top lid is locked closed with respect to the container body such that the interior cavity of the weapon container is substantially enclosed when the lock assembly is in the first position. The top lid may be moved to open the weapon container, via operator actuation of the container opening assembly, when the lock assembly is in the second position.

DETAILED DESCRIPTION OF THE INVENTION




The present invention is more particularly described in the following exemplary embodiments that are intended as illustrative only since numerous modifications and variations therein will be apparent to those skilled in the art. As used herein, “a,” “an,” or “the” can mean one or more, depending upon the context in which it is used. The preferred embodiments are now described with reference to the figures, in which like reference characters indicate like parts throughout the several views.




Turning now to the drawings and particular

FIGS. 7 and 11

, a weapon container is enumerated generally as at


10


. Although the invention described herein can be advantageous for use with any kind of weapon container that can be exposed to a positive accelerated gravity environment, it will find its most common utility with an aircraft mounted weapon container in which a lethal or non-lethal weapon is stored.




Referring to

FIGS. 1-6

, a first embodiment of a gravity sensitive lock assembly


20


that is movable between a first, locked, position and a second, unlocked, position upon application of an accelerated gravity condition of sufficient magnitude is shown. The first embodiment of the lock assembly


20


has a locking member


22


, a lever member


24


, and a knuckle assembly


26


pivotally connected intermediate the locking bar member


22


and the lever member


24


. The lever member


24


has an upper surface


31


, a distal end


30


, an opposed proximal end


32


, and defines a longitudinal axis W. The proximal end


32


of the lever member


24


is pivotally connected to a substantially upright planar mounting plate


40


via a first mounting pin


50


. As shown in the figures, the first mounting pin


50


extends therethrough a first bore


28


defined in the lever member


24


near the proximal end of the lever member


24


.




A shoulder stop


55


that extends from the mounting plate may be provided. In one example, the shoulder stop is constructed and arranged to receive an adjustable fastener


56


such as, for example, a screw or bolt which moves on an axis parallel to the mounting plate. As one will appreciate, the mounting plate


40


may comprise at least a portion of the interior surface of the interior cavity of the weapon container.




The proximal end of the lever member also includes an actuation arm


40


that extends away therefrom. In one example, an end portion


42


of the actuation arm bends inward toward the distal end of the lever member. The distal end


30


of the lever member


24


includes a weight


34


that is attached thereto. As one skilled in the art will appreciate, the weight


34


may be selectably attached to alternative portions of the distal end


30


of the lever member


24


so that the respective gravitational level at which the lock assembly


20


moves from the first, locked, position to the second, unlocked, position may be selected by the operator. The weight


34


is positioned thereon the distal end


30


of the lever member


24


allows the lever member


24


to pivot downwardly about the first mounting pin


50


upon the application of a positive, accelerated gravity condition of a predetermined level. The relative gravitational level for actuation of the lock assembly


20


may be selected to be, for example, in the range from about 1.1 to 4.5 Gs; more preferably from 1.1 to 3.5 Gs; and still more preferred, from 1.2 to 2.5 Gs. In one example, the distal end


30


of the lever member


24


may have at least one slot


36


extending longitudinally proximate the distal end


24


of the level member


24


. The weight


34


can be selectively connected to the slot


36


to provide the desired gravitational level for actuation.




Further, the lock assembly may include a spring plate


46


that is mounted onto the first mounting pin and is fixed to the mounting plate intermediate the mounting plate and the lever member. The spring plate has a spring shoulder stop extending away therefrom. A first spring


75


may be included and is positioned onto the first mounting pin within a channel


44


defined in the lever member so that the first spring


75


is disposed within and acts thereon a portion of the formed channel


44


of the lever member


24


to urge the lever member


24


back into its original position consistent with a normal, unaccelerated, gravity condition. Thus, in this example, the lever member


24


would pivot downwardly about the first mounting pin


50


against the resistance of the first spring


75


upon the application of a positive accelerated gravity condition of sufficient magnitude.




The locking member


22


has a first end


21


, an opposed second end


23


, and defines a longitudinal axis L. At least a portion of the first end


21


of the locking member


22


may be in selective operable contact with a portion of a container opening assembly. The second end


23


of the locking bar assembly


20


is pivotally connected to a portion of the knuckle assembly


22


. Upon application of the targeted gravitational level, the locking member


22


is drawn downwardly along the longitudinal axis L. A plurality of guide pins


52


extending from the mounting plate


40


are connected to a face plate


47


to aid in constraining the locking member


22


to movement along the longitudinal axis L.




The knuckle assembly


26


has a first member


25


, a pivotally connected second member


27


, and a pivotally connected mounting member


60


. In one example, each of the first and second members preferably has a substantially U-shape and is formed from two opposing planar plates


33


joined by a support member


35


. Each of the planar plates has an upper end


36


and a lower end


37


. In operation, the first member


22


has its upper end pivotally connected to a portion of the second end


23


of the locking member


22


, to form a second joint


72


and its lower end is pivotally connected to the upper end of the second member


27


, to form a first joint


71


.




The mounting member


60


preferably is T-shaped and has a first mounting end


61


, an opposed second mounting end


62


, and a third mounting end


63


intermediate the first mounting end and the second mounting end. Each of the respective first, second and third mounting ends defining an opening


64


therethrough. As shown in the figures, the first mounting pin


50


extends through and is connected to the first mounting end


61


of the mounting member


60


. The locking assembly further comprises a second mounting pin


54


that extends away from the mounting plate and is spaced from the first mounting pin. The second mounting pin is connected to the second mounting end


62


of the mounting member so that the mounting member


60


is fixed relative to the mounting plate. As one will observe, the second mounting pin


54


and first mounting pin


50


are both connected to the mounting plate


40


so that they are offset with respect to the extended longitudinal axis L of the locking bar member


22


. In one example, the first and the second mounting pins


50


,


54


are positioned substantially parallel to one side of the longitudinal axis L.




The lower end


37


of the second member


27


is pivotally connected to a third mounting pin


53


extending between the third, intermediate end, of the mounting member and the mounting plate to form a third joint


73


. As one skilled in the art will appreciate, the respective pivot connections of the first member


25


and the locking member


22


and the second bar member


27


and the mounting member


60


, i.e., the second and third joints, are substantially co-axial with respect to the extended longitudinal axis L of the locking member


22


.




Thus, in an unaccelerated gravity condition in which the lock assembly


20


is in the first, locked condition, the first joint is oriented offset from the extended longitudinal axis L and outwardly toward the proximal end


32


of the lever member


24


in a first overcenter position. Also, in one example, a portion of the support member of the second member is in resting contact with a portion of the second mounting pin. In an alternative example, a portion of the upper surface


31


of the lever member is in contact with the fastener


56


in the shoulder stop


55


of the mounting plate


40


and the second member is spaced from the second mounting pin


54


. Thus, as one will appreciate, in the alternative example, the first joint is less offset and is closer to the longitudinal axis L when in the first overcenter position.




In the first, locked, position of the lock assembly


20


, any force downwardly applied to the first end


21


of the locking member


22


would merely force the respective portions of the knuckle assembly


26


against portions of the second mounting pin that constrains the locking member


22


from downward movement resulting from the downward application of force.




In one example, the bore


28


in the lever member


24


for pivotal receipt of the first mounting pin


50


is substantially co-axial to the longitudinal axis W of the lever member


24


. The second member


27


is preferable pivotally connected to the mounting member


60


offset from the longitudinal axis W of the lever member


24


and above the upper surface


31


the lever member


24


. As one will appreciate, upon the application of the targeted accelerated gravitational condition, the lever member


24


pivots downwardly and around the first mounting pin


50


which causes a portion of the end portion


42


of the actuation arm


40


to push against a portion of the second member


27


. As a result, the actuating arm


40


forces the second member


27


away from the first overcenter position toward a second overcenter position in which the pivot connection between the first and second members


25


,


27


is oriented offset from the extended longitudinal axis L and outwardly toward the distal end


30


of the lever member


24


. In this second overcenter position, the second end


23


of the locking member


22


is drawn downwardly toward the lever member


24


which places the lock assembly into the second, unlocked, position.




The lock assembly


20


may also include a second spring


77


that is connected to a pivot pin joining the upper end of the first member and the second end of the locking member. As one will appreciate, the respective ends of the second spring act of a portion of the locking member proximate the second end and a portion of the support member of the first member to urge the knuckle assembly


26


back to the first overcenter position from the second overcenter position upon the resumption of a normal, unaccelerated, gravitational condition.




The locking assembly may also include a third spring


79


. One end of the third spring is connected to a portion of the locking member that is intermediate the first end and second end thereof. The other end of the third spring is connected to one of the guide pins that is near the upper end off the mounting plate (i.e., near the first end of the locking member). The third spring helps to urge the locking member to its extended position from the collapsed position.




Referring now to

FIGS. 7-10

, a first embodiment of a weapon container


10


having an opening assembly


100


that is operatively connected to the first embodiment of the gravity sensitive lock assembly


20


described above is shown. As shown in

FIG. 3

, the weapon container


10


has a container body


80


and a top lid


86


. The container body includes a first side section


81


, an opposing second side section


82


, a bottom section


83


opposed to the top lid


86


, a first end section


84


, and an opposing second end section


85


. As one skilled in the art will appreciate, edge portions of the first side section, the first and second end sections, and the bottom section are connected together along respective common edges. The second side section and the bottom section are pivotally connected together along common edge such that portions of the second side section can be placed into operative contact with side edge portions of the first and second end sections. Similarly, the second side section and the top lid are connected along a common edge (in one example, pivotally connected) such that portions of the top lid may be placed into operative contact with the top edge portions of the respective first and second end sections. In a closed and locked configuration, in which the lock assembly is in the first, locked, position, the respective first and second ends, the bottom, the top lid, and the first and second sides form a closed container.




The interior surfaces of the bottom section, the first and second end sections, the first and second side sections, and the top lid define an interior weapon container cavity


87


. A common partition


102


extends from a portion of the interior surface of the first end section to a portion of the interior surface of the second end section and separates the weapon container cavity into a weapon storage compartment


104


and a lock assembly compartment


106


. The weapon storage compartment


104


preferably has a weapon holster


106


for secure receipt and storage of a weapon within the interior of the weapon container


10


.




The weapon container


10


may also have a view port


110


to allow for visual inspection of the presence of the weapon within the weapon container


10


. The view port


110


is sized so that the weapon cannot be removed through the view port and is preferably covered with a penetration resistant and optically translucent material. Further, the weapon container


10


may also have an electrical connection (not shown) in communication with an electrical power source and a weapon power source, such as, for example, the power source for an electrical discharge weapon.




The weapon container


10


shown in

FIG. 7

may be mounted onto any surface of the aircraft and allows for ready access to the weapon contained therein upon the application of the predetermined level of the accelerated positive gravitational condition, which moves the first embodiment of the lock assembly


20


from the first, locked, position to the second, unlocked, position, and upon the application of operator force to the container opening assembly


100


of the weapon container


10


.




As shown in

FIGS. 7-10

, the opening assembly


100


of the weapon container


10


includes at least one hinge bar


120


and a handle member


130


. The hinge bar


120


is pivotally connected to the bottom surface of the top lid and is in selective locking contact with a flange


122


depending substantially perpendicular from a top edge of the first side portion of the weapon container


10


. The flange


122


defines at least one opening


124


extending therethrough that is sized for selective operative receipt of an upwardly extending male protrusion


126


proximate the distal end of the hinge bar


120


. The top lid of the weapon container


10


defines an opening


132


that is complementarily sized for receipt of the handle member


130


. In the closed and locked configuration, the handle member


130


is connected to a portion of the hinge bar


120


so that it is substantially co-planer with respect to the top lid of the weapon container


10


.




A portion of the first end


21


of the locking member


22


of the locking assembly


20


may be in contact with a portion of bottom edge of the hinge bar


120


(preferably proximate the distal end of the hinge bar


120


). Alternatively, a stop member


128


may extend between an opposing pair of hinge bars


120


such that a portion of the first end


21


of the locking member


22


may be in contact with a portion of the stop member


128


. Thus, in operation, upon the movement of the locking assembly


20


from the first, locked, position to the second, unlocked, position and the resultant downward movement of the locking member


22


away from the hinge bar


120


or stop member


128


, the hinge bar


120


, upon the application of force by the operator onto the surface of the handle member


130


, may be pivotally rotated inwardly into the interior of the weapons container


10


. The inward rotation of the hinge bar


120


allows the male protrusion


126


of the hinge bar


120


that was operatively received therein the opening


124


of the flange


122


in the closed and locked configuration to be withdrawn inwardly toward the interior of the weapon container


10


which disengages the hinge bar


120


of the opening assembly


100


from the flange


122


. Then, as shown in

FIG. 7

, the weapon container


10


may be opened for access to the weapon storage compartment


104


.




As one skilled in the art will appreciate, the weapon container


10


cannot be opened without the application of an accelerated positive gravitational level of sufficient magnitude because the hinge bar


120


is constrained from the necessary rotational movement due to its operative contact with the first end


21


of the locking member


22


of the first embodiment of the lock assembly


20


. Since no downward movement of the locking ember


22


is provided for when the lock assembly is in the first, locked, position (and the knuckle assembly


26


is in the first over-center position), the handle member


130


cannot be “pushed” and the connected hinge bar


120


cannot be “pushed inwardly” into the interior of the weapon container


10


. Thus, the male protrusion


126


of the hinge bar


120


is retained within the opening


124


in the flange


122


of the weapon container


10


.




Referring now to

FIGS. 11-13D

, a second embodiment of a weapon container


12


having a container opening assembly


200


operatively connected to the first embodiment of the gravity sensitive lock assembly


20


described above is shown. As shown in

FIG. 7

, the weapon container


12


has a container body


90


and a top lid


96


. The container body includes a first side section


91


, an opposing second side section


92


, a bottom section


93


that opposes the top lid, a first end section


94


, and an opposing second end section


95


. As one skilled in the art will appreciate, edge portions of the first and second side sections, the first and second end sections, and the bottom section are connected together along respective common edges.




Each of the first and second side portions of the weapon container


12


may have a flange


202


depending substantially perpendicular therefrom the respective top edge of the first and second side portions. Each flange


202


defines a plurality of openings


204


. As one skilled in the art will appreciate, each opening


204


provides for operative receipt of a fastener


98


for connection of the weapon container


12


to aircraft equipment railings. In a closed and locked configuration, in which the lock assembly


20


is in the first, locked, position, the respective first and second ends, the bottom, the top lid, and the first and second sides form a closed weapon container


12


.




The interior surfaces of the bottom section, the first and second end sections, the first and second side sections, and the top lid define an interior weapon container cavity


97


. The weapon container


12


may have a view port (not shown) in the top lid to allow for visual inspection of the presence of the weapon within the container cavity. The view port is preferably sized so that the weapon cannot be removed through the view port and is preferably covered with a penetration resistant and optically translucent material. Further, the weapon container


12


may also have an electrical connection (not shown) in communication with an electrical power source and a weapon power source, such as, for example, the power source for an electrical discharge weapon.




The weapon container


12


shown in

FIG. 11

allows for ready access to the weapon contained therein upon the application of the targeted accelerated positive gravitational condition, which moves the first embodiment of the lock assembly


20


from the first, locked, position to the second, unlocked, position, and upon the application of operator force to the container opening assembly


200


of the weapon container


12


. In operation, upon movement of the lock assembly


20


from the first, locked, position to the second, unlocked, position, the opening assembly


200


of the weapon container


12


is actuated by the operator so that the top lid may be moved relative to the top edges of the side and end portions of the weapon container


12


. In one example, the top lid is pivotally connected along a common edge to one of the side portions of the weapon container


12


so that the interior of the weapon container


12


may be accessed by pivoting the top lid about the common edge after the opening assembly


200


is actuated.




Alternatively, in an example of the weapon container


12


shown in

FIGS. 12A-12D

, the weapon container


12


may also have a tray system


250


slidably disposed therein the cavity of the weapon container


12


. In this example, the tray system


250


is connected to a portion of the bottom surface of the top lid of the weapon container


12


. The tray system


250


preferably has a weapon holster for secure receipt and storage of the weapon within the interior cavity of the weapon container


12


.




In operation, a tee handle member


222


, which is operatively connected to the top lid of the weapon container


12


and forms a portion of the opening assembly


200


, is pulled upwardly along the longitudinal axis of the weapon container


12


. As the top lid is drawn upwardly away from the top edges of the side and end portions, a base tray of the tray system


250


is drawn up toward the top edges of the side and end portions until a limit stop is reached. When the limit stop is reached, the top lid is pivoted to the side around a pivot


252


in the tray system


250


and the weapon is exposed.




The container opening assembly


200


of the second embodiment of the weapon container includes a hinge plate


224


, an actuation button


226


, at least one latch plate


228


, and the tee handle member


222


. As shown in

FIG. 11

, the top lid of the weapon container


12


defines at least two openings. The top end of the actuation button


226


extends through one of the openings and is positioned above the top surface of the top lid. Similarly, the top, T-shaped, portion of the tee handle member


222


is positioned above the top surface of the top lid for actuation by the operator. As one will appreciate, substantially all of the other portions of the container opening assembly


200


for the second embodiment of the weapon container


12


are concealed beneath the top lid of the weapon container


12


when the weapon container


12


is in a closed and locked configuration.




Referring to

FIGS. 13A-13D

, the actuation button


226


defines a slot


227


intermediate the top and bottom ends of the actuation button


226


. The tee handle member


222


has a rod


223


, which is connected to the top, T-shaped, portion of the tee handle member


222


, and a semicircular flange


221


that extends substantially perpendicular from a portion of the rod


223


. The edge of the semicircular flange


221


has an arcuate cutout


230


shaped to be complementary to at least a portion of the exterior surface of the actuation button


226


. Thus, in operation, when the actuation button


226


is in a first, fully extended, position, at least a portion of the exterior surface of the actuation button


226


intermediate the slot


227


and the bottom end of the actuation button


226


is in contact with the actuate cutout


230


in the edge of the semicircular flange


221


of the tee handle member


222


. Because of the interference between the arcuate cutout


230


and the actuation button


226


, the tee handle member


222


is prevented from being rotated about its longitudinal axis when the actuation button


226


is in the first, extended, position.




Each latch plate


228


has at least one male protrusion


229


extending from one edge of the latch plate


228


. Each male protrusion


229


is operative received within a complementarily sized slot


240


defined in the side portion of the weapon container


12


proximate the top end of the side portion. In one example, a single latch plate


228


is used and the top lid is pivotally connected along a common edge to one side portion of the weapon container


12


. As one will appreciate, the slot


240


for engagement of the male protrusion


229


of the latch plate


228


would be in the opposing side portion of the weapon container


12


.




In another example, as shown in

FIGS. 13A-13D

, a pair of opposing latch plates


128


may be used. The pair of opposing latch plates


228


are in partial overlying registration and are operatively connected to the tee handle member


222


. In this example, the male protrusions


229


of the respective latch plates


128


would be operatively received within slots


240


in the respective opposing-side portions. As one skilled in the art will appreciate, upon rotation of the tee handle member


222


about its longitudinal axis, the edge of the each latch plate


228


having a male protrusion


229


is drawn inward toward the tee handle member


222


. The movement of the latch plate


228


causes the male protrusion of the latch plate


228


to be withdrawn from the slot


240


in the weapon container


12


so that the top lid may be operatively removed to expose the interior of the weapon container


12


.




To effect rotational movement of the tee handle member


222


, the slot


227


in the actuation button


226


is sized for operative receipt of a portion of the edge of the flange


221


of the tee handle member


222


. When the actuation button


226


is positioned in a second, depressed, position, the slot


227


is positioned substantially coplanar with the flange


21


of the tee handle member


222


for receipt of the edge of the flange


221


. This allows for the operative rotation of the tee handle member


222


about its longitudinal axis which will, as noted above, cause the latch plates


128


to retract and release from the engaged portions of the weapon container


12


.




Thus, in order for the weapon container


12


to be opened, the actuation button


226


must be moved from the first, extended, position, to the second, depressed, position. The hinge plate


224


is pivotally connected to the bottom surface of the top lid. A portion of the hinge plate


224


is in selective contact with the bottom surface of the actuation button


226


so that downward pivotal movement of the hinge plate


224


will allow the actuation button


226


to be depressed from the first, extended, position to the second, depressed, position. A portion of the bottom surface of the hinge plate


224


is in operative contact with a portion of the first end


21


of the locking member


22


of the first embodiment of the lock assembly


20


so that, when the lock assembly


20


is in the first, locked, position, the hinge plate


224


is constrained from pivotal movement relative to the bottom surface of the top lid so that the actuation button


226


is maintained in the first, extended, position and the tee handle member


222


cannot be turned.




As one will appreciate, the actuation button


226


cannot be forced, through application of an external force to the top end of the actuation button


226


, from the extended position to the depressed position, until the lock assembly


20


moves from the first, locked, position to the second, unlocked, position. As one will further appreciate, when the lock assembly


20


moves to the unlocked position upon application of an accelerated gravity condition of sufficient magnitude, the hinge plate


224


pivots down and away relative to the bottom of the top lid which allows the actuation button


226


to be depressed from the extended position to the depressed position.




Referring now to

FIGS. 14 and 15

, a second embodiment of a gravity sensitive lock assembly


300


for a weapon container is shown. The second embodiment of the gravity sensitive lock assembly


300


includes a pendulum member


310


, a mounting boss


320


, and a spring


330


. The mounting boss


320


has a pair of opposing flanges


322


connected to the bottom surface of the top lid of the weapon container. The flanges


322


extend substantially perpendicular from the bottom surface of the top lid. The mounting boss


320


further includes a pivot pin


324


mounted to and extending therebetween the opposing flanges


322


such that the axis of the pivot pin


324


is substantially parallel to the bottom surface of the top lid.




The pendulum member


310


defines a bore


312


for operative receipt of the pivot pin


324


so that the pendulum member


310


is pivotally mounted to the mounting boss


320


. The pendulum member


310


is preferably made of a relatively heavy material and is movable with respect to the mounting boss


320


to the gravitational force applied to the locking assembly


300


. The pendulum member


310


has a short arm


314


and a long arm


316


formed in a generally “L” shape. The bore


312


of the pendulum member


310


is proximate the juncture of the long arm


316


and the short arm


314


of the pendulum member


310


. The short arm


314


is in the form of a two connected quadrants of a two different sized disks and has a first arcuate edge surface


317


circumscribing an arc of approximately 3 to 30°, a second arcuate edge surface


318


circumscribing an arc of approximately 3 to 30°, and a third edge surface


319


extending between and connecting the first and second arcuate edge surfaces


317


,


318


. The first arcuate edge surface


318


is spaced from the bore


312


of the pendulum member


310


a first distance d


1


and the second arcuate edge surface


318


is spaced from the bore


312


of the pendulum member


310


a second distance d


2


which is less than the first distance. As one will appreciate the third edge surface


319


may be tapered to ease the transition from the first arcuate edge surface


317


to the second arcuate edge surface


318


.




Referring to

FIG. 10

, the container opening assembly


200


discussed above in respect to the second embodiment of the weapon container


12


is used with the exception that the hinge plate


224


is not required. The second embodiment of the lock assembly


300


is in operative contact with the actuation button


226


of the container opening assembly


200


. In

FIG. 10

, the lock assembly


300


is shown in the first, locked, position, wherein a portion of the bottom of the actuation button


226


in contact with the first arcuate edge surface


317


. The spring


330


is connected to a portion of the long arm


316


of the pendulum member


310


intermediate the bore


312


of the pendulum member


310


and the distal end of the long arm


316


to urge the pendulum member


310


into its original position consistent with a normal, unaccelerated, gravity condition. In this original position, a portion of the bottom of the actuation button


226


is in contact with the first arcuate edge surface


317


. Thus, in this example, the pendulum member


310


pivot downwardly about the pivot pin


324


against the resistance of the spring


330


upon the application of a positive accelerated gravity condition of sufficient magnitude.




As one would appreciate, a weight


344


may be selectively applied to the long arm


316


of the pendulum member


310


so that a predetermined gravitational force level can be selected for movement from the first, locked, position to the second, unlocked, position. The engagement of the first arcuate edge surface


317


and the bottom of actuation button


226


prevents the actuation button


226


from being depressed from the extended position to the depressed position.




Referring now to

FIG. 14

, the lock assembly


300


is shown in the second, unlocked, position during the application of the targeted gravitational force level. The application of the gravitational force causes the long arm


316


and the short arm


314


of the pendulum member


310


to pivot with respect to the pivot pin


324


against the resistance of the spring


330


. The pivoting of the pendulum member


310


allows the third edge surface


319


of the pendulum member


310


and then, when the targeted gravitation force level is reached, the second arcuate edge surface


318


of the pendulum member


310


to be placed beneath a portion of the bottom of the actuation button


226


(i.e., the second, depressed, position). The bottom of the actuation button


226


is placed into contact with the second arcuate edge surface of the pendulum upon the downward application of force on the actuation button


226


by the operator. It is preferred that the bottom of the actuation button


226


include a bearing so that the pendulum member


310


is freely moveable with respect to the actuation button


226


. In this example, the bearing would be the portion of the actuation button


226


that is in contact with the pendulum edge surfaces. The difference between the first and second distances of the respective first and second arcuate edge surfaces


316


,


317


is sufficient to place the actuation button


226


in the second, depressed, position when a portion of bottom of the actuation button


226


is in contact with the second arcuate edge surface


318


which allows the flange of the tee handle member


222


to be received within the slot of the actuation button


226


.




As one will appreciate, upon the release of pressure upon the actuation button


226


and the reduction of the applied gravitational force below the targeted gravitational force, the bottom of the actuation button


226


will ride sequentially across the second arcuate edge surface


318


, the third edge surface


319


, until engaging the first arcuate edge surface


317


as the pendulum member


310


pivots back to its original unaccelerated position under the applied force of the spring


330


.
