This invention relates to a gun lock, a device for locking a gun or parts thereof by securely situating the gun or parts thereof such as the trigger and the trigger guard between a gun lock base and a locking base. The gun lock base house a plurality of spring loaded pins, herein also simply referred to as pin, for totally surrounding the gun or parts of the gun such as the trigger and/or the trigger guard when placed on top of the pins. The gun lock base in the example herein pairs with a locking base housing a latch plate for locking the gun lock when an engagement tooth on the latch plate engages with the locking teeth on the locking posts situated on the gun lock base. The plurality of spring loaded pins covering the surface of a gun lock base to immobilize the gun, trigger or trigger guard is an aspect of this invention that can be implemented with other locking bases to improve their performance. The claimed device can also be used to lock other objects in place aside from a gun or parts of the gun.
Due to the rise of burglaries and other violent crimes occurring in residences, more and more civilians are purchasing handguns to defend themselves. Thousands of shotguns and rifles are purchased each year not only for home protection but also for sports such as hunting, trap and skeet shooting and the like. Most of these deadly weapons, collectively referred to herein simply as gun or guns, are stored in residences, mostly in areas like the drawers, closets or under the bed. Although adults usually lock the drawer or closet where the gun is stored, history has proven that this has not prevented unauthorized use of the gun. Children and adolescents always seem to find them and their curiosity at times have cost human lives resulting from the accidental discharge of the gun. Some have also used it intentionally, judging from the number of suicides and murders, for example, the use of the gun against classmates and teachers in schools. There is therefore a need for a good gun lock and users should not wait until they are required by laws mandating the use of a gun lock because the responsibility of owning a gun should include the responsibility of preventing its unauthorized use.
This problem has been recognized in the design of several gun locks. Several of these designs manually place restraining pins one by one to prevent the movement of the trigger or prevent the movement of a locking device. Most of these designs require time to place the pins which encourage one to resort to the traditional way of just hiding the gun without the gun lock. U.S. Pat. No. 5,437,119 propose the use of pins to prevent trigger movement and aid in the positioning of a trigger blocking structure relative to the trigger and the trigger guard. The proposed pins herein, as stated, have to be manually placed by the user into the user selected conical entrance section of the pin holes. This requires time since one or two pins are always not enough to prevent the trigger movement. Other patents, U.S. Pat. No. 5,918,402 and U.S. Pat. No. 6,457,272 uses the same concept as U.S. Pat. No. 5,437,119 of selecting and manually placing pins that extend through two opposing body members holding the trigger in between. None of these inventions provide an array of spring loaded pins that would restrain a gun, a trigger and or a trigger head at whatever position it is laid between the opposing bodies. U.S. Pat. No. 5,392,552 even if it uses a spring loaded pin, this is used to prevent a locking assembly from shifting relative to the trigger guard because of a locking member that protrudes from the locking plate which will hit the trigger if the locking plate accidentally shifts. The spring loaded pin act as a spacer by having the tip of the spring loaded pin extend out perpendicularly from the locking plate and abut at the surface of the housing opposite the locking plate. The shifting is prevented by the frictional force between the planar tip of the pin and a planar surface of the housing. Additionally, since the pins are used as a spacer, the gun should always be carefully positioned in such a way that there are pins between the locking member and the trigger. Further, wear and tear between the tip of the pin and the surface of the locking plate may loosen and eventually allow some shifting between the locking plate and the housing. The implementation of a plurality of spring loaded pins of the claimed invention for automatically preventing the movement of the trigger or trigger guard may be incorporated in the above cited patented inventions as an improvement.
It is an object of this invention to provide pins that need no manual selection and placement to protect and provide automatic immobilization of the trigger and the trigger guard.
It is also an object of this invention to provide a gun lock that can be operated safely and quickly.
It is a further object of this invention to provide a locking mechanism that is simple in design but securely locks the gun between the gun lock base and the locking base.
It is also a further object of this invention to provide a mechanism for opening an electronically triggered gun lock when the power supplied from a battery is consumed.
SUMMARYThis invention relates to a device for locking a gun, a gun lock, comprising a gun lock base having a top surface and a bottom surface, the top surface comprising a plurality of spring loaded pins covering the top surface of the gun lock base, the plurality of spring loaded pins automatically surrounding and immobilizing a gun or parts thereof placed on the top surface; a locking base; and, means for locking the gun or parts thereof between the gun lock base and the locking base. The plurality of spring loaded pins recess or release according to the pressure exerted by the object, herein a gun or parts thereof. The gun lock can include a locking post with locking teeth protruding from the gun lock base for engagement with an engagement tooth on the locking base when the device is in the lock position. The device can be locked or unlocked mechanically or electronically. The object such as the gun or parts thereof is sandwiched between the gun lock base and the locking base before locking the device. An example of a locking base suitable for pairing with the gun lock base comprises a latch plate having an engagement tooth for engagement with the locking teeth of the locking post. For a quick immobilization of the object, the plurality of pins on the top surface should be allowed to recess to or release from the top surface of the gun lock base according to the pressure exerted by the gun or parts thereof placed on top of the pins or on the top surface of the gun lock base. Each pin of the plurality of spring loaded pins are held by a channel of a plurality of channels or placed between interwoven strips of material on the gun lock base. Each spring loaded pin is kept inside the channel or between the interwoven strips of material on the gun lock base by an annular stopper on top of a spring enveloped portion of the pin and a plate placed over the annular stopper. A cover may be placed on the top of the plate to prevent surface scratching between the gun lock base and the gun or parts thereof. The cover has holes corresponding to each channel housing a spring loaded pin thereby allowing all the spring loaded pins to go through the cover. The cover is usually made of a rubber based material or soft flexible plastic material. It is recommended for the cover to have a smooth inner surface and a roughened outer surface. In this gun lock base and locking base pair that are locked mechanically, the latch plate has a cam boss and the key locking cylinder has a cam head. The cam boss and the cam head are made to abut each other when the device is locked. To prevent undesired movement of the latch plate, a cover plate may be placed on top of the latch plate. As in the gun lock base above, a pad may also be placed on top of the cover plate to prevent surface scratching between the locking base and the gun or parts thereof. The pad is similar to the cover of the gun lock base except that the pad does not have holes.
For a gun lock device that is operated electronically, instead of a key locking cylinder, the locking mechanism utilizes a solenoid assembly communicating with an electronic logic board, the solenoid assembly having a solenoid pin lodging on a solenoid receiver on the latch plate after engaging the engagement tooth on the latch plate with the locking teeth on the locking post. The device is unlocked by an entry of a code.
The locking mechanism can be reinforced with a cable threading through the gun barrel or magazine or chamber of the gun.
A method for mechanically locking and unlocking an object, a gun or parts thereof, between a gun lock base and a locking base described above, comprises placing the object on the top surface of the gun lock base; automatically surrounding and immobilizing the object on the top surface by the plurality of spring loaded pins; pairing the gun lock base with the locking base by introducing the locking post into the locking base; engaging an engagement tooth on the latch plate-with the locking teeth on the locking post; locking the object between the gun lock base and the locking base by abutting the cam head connected to the key locking cylinder with the cam boss on the latch plate through a turn of the key on the key locking cylinder; and, unlocking the object from the gun lock base and the locking base by turning the key on a direction opposite a direction for locking the object and releasing the engagement tooth from the locking teeth.
A method for electronically locking an object, a gun or parts thereof, between a gun lock base and a locking base controlled electronically as described above, comprises: placing the object on the top surface of the gun lock base; automatically surrounding and immobilizing the object on the top surface by the plurality of spring loaded pins; pairing the gun lock base with the locking base by introducing the locking post into the locking base; engaging an engagement tooth on the latch plate with the locking teeth on the locking post; locking the object between the gun lock base and the locking base by lodging a solenoid pin of the solenoid assembly into a solenoid receiver; and, unlocking the object from the gun lock base and the locking base by entry of a code on the touching pad to dislodge the solenoid pin from the solenoid receiver and releasing the engagement tooth from the locking teeth.
Other embodiments of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein it shows and describes only certain embodiments of the invention by way of illustration. As will be realized, the invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
BRIEF DESCRIPTION OF THE DRAWINGAspects of the present invention are illustrated by way of example, and not by way of limitation, in the accompanying drawings, wherein:
The detailed description represented-herein is not intended to represent the only way or the only embodiment in which the claimed invention may be practiced. The description herein is provided merely as an example or examples or illustrations of the claimed invention and should not be construed as the only way or as preferred or advantageous over other embodiments or means of practicing the invention. Any means of surrounding an object, herein a trigger and a trigger guard as examples, with a plurality of pins that automatically recess proportionately according to the pressure exerted by the object, usually its weight, is within the scope of this invention. In the example of the claimed gun lock herein, the restraining function of the plurality of pins automatically surrounding the trigger and/or the trigger guard on the gun lock base is coupled with a locking mechanism utilizing a latching plate with at least one engagement tooth for engaging with a corresponding locking teeth controlled by either a locking cylinder in a mechanical operation or a solenoid assembly in an electronic operation. Consequently, adaptations of the latch plate described is also within the scope of this invention. It is to be appreciated, however, that the claimed pins on the gun lock base by themselves or the latch plate mechanism by itself can not independently do the intended function. Their respective functions have to be coordinated with each other or one paired with another device modified to function synchronously with either the pins or the latch plate. The detailed description includes specific details to provide a thorough understanding of the claimed invention and it is apparent to those skilled in the art that the claimed invention may be practiced without these specific details. In some instances, well known structures and devices are shown in block diagrams or drawn with broken lines in order to avoid obscuring the main concepts of the invention.
The gun lock device comprises two major parts, a gun lock base 1 and a locking base 2 as shown in
The components of the gun lock base illustrated here includes a hollow holder, a nest, spring loaded pins, a plate and an optional cover. The hollow holder 5 has a planar back panel or bottom surface and at least one locking post 6 protruding from the inside wall of the back panel or bottom surface at a location where the locking teeth 7 on the locking post 6 can engage with an engagement tooth/teeth 8 on a latch plate 9. The locking posts could be molded in place or it could be made up of two separate metal parts, fastened or pinned in place. The metals that can be used are injection molded zinc die cast, steel, aluminum, brass or even injection molded plastic. Although two locking posts are illustrated in the drawings, one locking post is sufficient or more than two locking posts are also possible. A nest 10, a block having the same outside lateral contour as the inside wall of the hollow holder 5, is introduced, fits into and fills the open space of the hollow holder. Alternately, the nest and the hollow holder can be one piece. The nest could be plastic injection molded. An alternative would be to construct the nest like an egg crate made from strips of material that are interwoven. The material could be plastic or metal. The top surface of the nest rests colinearly with the peripheral lip 11 at the tip of the hollow holder 5. The nest 10 or the gun lock base, if the hollow holder and nest are in one piece, has an opening 12 to accommodate a protruding locking post 6 and also consists of a plurality of cylindrical channels 13 arranged in an array of rows and columns as shown in
Before placement of the trigger and trigger guard on top of the plate, a cover 25 made of rubber based material or soft flexible plastic material such as silicone, stretchable rubber or urethane injection molded material is recommended to be placed on top of the plate 20 to prevent scratching their respective surfaces. The cover have holes 26 identical to the holes 21 of the plate which are above the channels 13 on the nests. The holes 26 allow all the pins protruding from the plate 20 to now protrude over the cover. The inner surface of the cover is smooth and lays flat on top of the plate. The outer surface 28 of the cover, however is preferably rough, roughened for example by small spikes 27 between the array of holes 26, to provide additional restraint of motion on the object placed on top of the cover 25 by the frictional force between the spikes and the object, herein the trigger and the trigger guard. The cover is held or anchored on top of the plate, for example, through an inward indentation 29 at the inner surface of the lateral sides of the cover accommodating the protruding side edges of the holder 5 and the plate 20 as shown in
A gun lock base 1 herein pairs with a locking base 2 that is operated either by a key or electronically by a solenoid following a correct entry of a secret code.
A locking base operated mechanically by a key 3 is assembled by introducing a key locking cylinder 30 into an opening 31 of a hollow housing 32 having a planar face 33 and a hollow interior 34. The key and the key locking cylinder are off the shelf items, that is, commercially available. Before the key locking cylinder is placed at the opening 31, a flat label 35 identifying the product such as a trademark, the manufacturer, etc. may be placed or attached to the planar face 33 of the hollow housing 32. To secure the key locking cylinder to the housing 32, a hex nut 36 is screwed into matching grooves 37 of the key locking cylinder. It is best to flip the housing during this assembly to facilitate access to the key locking cylinder as shown in
The hollow housing 32 of the mechanical locking base 2 has three cuts 44 on the ends of the lateral sides 45 opposite the planar face 33. These cuts extends into the bottom peripheral edge of the housing 32 as shown in
To lock a gun in place using the above mechanical gun lock, the trigger 57 and the trigger guard 58 is laid on top of the gun lock base 1. This will cause the spring loaded pins 15 present on all areas on the top surface of the gun lock base not occupied by the trigger and the trigger guard and in this example, by the locking post, to automatically surround the trigger and the trigger guard. To show position of the trigger and the trigger guard relative to the pins,
An electronically operated locking base 2 pairs with the same gun lock base and uses the same hollow housing 32 for its assembly. The electronic locking base will be identified by elocking base 2′ for differentiation. An example of an elocking base is shown here. The elocking base 2′ is assembled by placing a touching pad 4, a number or letter pad or a combination of these, into an etched surface 61, on the planar face 33 of the housing 32 as shown in
The operation of the electronic gun lock is the same as the mechanical gun lock. The only difference is on the device that locks or releases the latch plate from engagement with the locking posts. The mechanical gun lock uses the key locking cylinder while the electronic gun lock uses the solenoid assembly. As in the mechanical gun lock, to lock a gun, the trigger and the trigger guard are laid on top of the gun lock base which will cause the spring loaded pins to automatically surround the trigger and the trigger guard. The elocking base 2′ is then paired with the gun lock base similar to the mechanical gun lock with the elocking base in the unlock position unless one arm of the latch plate is enveloped by a spring as described above, in which case, the elocking base 2′ can be in the lock position. Once the tips of the pins are oriented between the spikes 56 on pad 55 or abut the surface of the cover plate 50, if a pad is not used, and the locking posts are in position inside the elocking base, that is, abutting the inner surface of the planar face 33, the end of the horizontal arm 46 of the latch plate 9 having the imprinted arrow is pushed against the direction of the arrow. This will engage the engagement teeth on the latch plate with the locking teeth on the locking posts. The device is locked when the solenoid pin 67 is lodged or engages with the solenoid receiver 76 on the latch plate. To unlock the electronic gun lock, the correct code should be inputted on the touching pad 4. Once the correct code is received, the solenoid assembly 64 is activated. Once activated, the solenoid pin 67 disengages from the solenoid receiver 76 by retracting into the solenoid body. With the solenoid pin out of the way, the latch plate 9 can be easily pushed to the unlock position, that is on the direction of the arrow, thereby disengaging the engagement teeth from the locking teeth on the locking posts. The details for locking and unlocking the electronic gun lock that is similar to the mechanical gun lock are not reiterated here.
If desired, the gun lock can be reinforced by a cable assembly having a cable 77 threading through the gun barrel and/or the magazine or the chamber of the gun to displace a round of ammunition that may otherwise be present on the gun. This can be done by several means. One method is to use a retainer 78 that can be introduced into an outer locking post 79 (this is one of the locking posts 6) of the gun lock base. The retainer can be made of injection molded zinc die cast metal. The retainer has one end 80 of the cable 77 staked permanently into one of its cylindrical opening (not shown in drawing). It is recommended to enclose the free end 82 of the cable with a cable tip 81, preferably but not necessarily made of injection molded zinc die cast or screw machined brass, aluminum, steel or stainless steel. The cable tip 81 is recommended to be-crimped or staked onto the cable 77. The cable can be made of plastic covered metal stranded cables similar to those used on bicycle locks. For simplicity of usage, it is recommended that the cable tip 81 have a convex surface 85 at a mid location as shown in
The engagement teeth of the latch plate may be molded with the latch plate or it may be designed as a retractable piece coupled to the latch plate as shown in
Although the latch plate 9 or 9a illustrated here has two engagement teeth, one tooth or more than two teeth can be incorporated into the latch plate. The same is true for the matching locking posts. The number is only limited by practical feasibility based on the size of the gun lock. Further, while a key locking cylinder and a solenoid assembly were used to lock the gun lock base, other mechanical or electronic means of locking the gun lock can be used.
Securing of the parts or the components together were herein taught to use screws. It should be appreciated that securing, coupling or connecting the parts with each other or with other components can be accomplished by other means or devices aside from screws. Also, while some parts are shown cylindrical in shape, it is easy to adopt the concept and modify the shape to a different geometric shape.
While the embodiments of the present invention have been described, it should be understood that various changes, adaptations, and modifications may be made therein without departing from the spirit of the invention and the scope of the claims.
