FIREARM SAFETY LOCK

Abstract

A firearm safety lock that includes a rotatable locking member for being moved into a lock position against a trigger guard of the firearm responsive to movement of the firearm into a holster to prevent removal of the firearm from the holster when in the lock position. An electronic circuit is mounted on the holster and operable to cause the locking rotor to move from the lock position into an unlock position responsive to movement of a coded key paired with a code programmed in the electronic circuit into a predetermined proximity to the electronic circuit.

DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

[0038] Referring now to the drawings, a conventional firearm “F” and prior art holster “H” is shown. The firearm “F” is inserted into a pocket of the holster with the nose of the barrel extending out of a bottom opening of the holster pocket and the firearm grip in a ready position to be gripped and extracted from the pocket of the holster “H”. One aspect of the invention is the ability to use a conventionally-shaped and sized holster by the addition of operating elements that are compact and do not interfere with the normal operation of the holster. However, the invention is applicable for use with types of holsters and other firearm-holding devices, so the use of the term “holster” in this application is used in the broad sense to mean a case for carrying a usually small item on the person. Thus, the term “holster” may include carry a handbag, briefcase, concealed carry garment or other object having a pocket within which a firearm can be stored when not in use, rather than only a holder worn on the waist, shoulder or on a saddle.

[0039] As shown in FIG. 2, a holster 10 according to one preferred embodiment of the invention includes an inner wall 12 and an outer wall 14 riveted or otherwise secured to the inner wall 12 to form a pocket 16 into which the firearm “F” is inserted. As is also conventional, the holster 10 includes a pair of belt clips 18 that permit the holster 10 to be secured to a waist belt of the user.

[0040] In accordance with the invention, a holster safety lock assembly 20 is mounted on the holster 10 and includes elements mounted on the outside of the outer wall 14 and on the inside of the pocket “P”. As is shown in FIG. 3, the lock assembly 20 also includes electronic control elements mounted on an inner face of the inner wall 12. These elements include a circuit board 22 having an antenna and appropriate control circuitry for providing contactless control, as described below powered by a flat battery 24. The circuit board 22 and battery 24 are housed under a cover 26 that can be secured to the inner wall 12 of the holster 10 with the same rivets used to secure the outer wall 14 to the inner wall 12, or with any other suitable connectors. Electric current is supplied to the electro-mechanical elements of the lock assembly 20 from the circuit board 22 by wiring 28 that can extend around a lower edge of the inner wall 12, as shown, through a port in the inner wall 12, or otherwise.

[0041] Referring to FIGS. 4A and 4B, the lock assembly 20, positioned in the holster pocket 16, includes a solenoid 32 that operates a spring-loaded plunger 34 with a spring 36 that is under compression and normally maintains the plunger 34 in an extended position, as shown. The lock assembly 20 is mounted on a base 38.

[0042] As best shown in FIG. 4A, a rotatably-mounted locking rotor 40 has a recess 42 that defines spaced-apart lobes 44, 46. By observing the position of the firearm “F”, it will be noted that the trigger guard “G” is in a position to engage the locking rotor 40 as it moves further in the direction of the lock assembly 20. The locking rotor 40 is mounted for rotation on a torsion spring 48 that biases the locking rotor 40 in the clockwise direction. The locking rotor 40 also includes a radially-extending shoulder 50 and a cam surface 52 against which the plunger 34 engages during rotation of the locking rotor 40.

[0043] Referring to FIGS. 5A and 5B, as the firearm “F” moves closer to the locking assembly 20, the locking rotor 40 is positioned to interfere with movement of the trigger guard “G” of the firearm “F” into the storage position in the holster “H”. The movement of the trigger guard “G” causes it to engage the lobe 44 of the locking rotor 40 rotating it clockwise and causing the lobe 46, which is the actual locking member, has a curved, hook shape, to also rotate clockwise, as shown.

[0044] As shown in FIGS. 6A and 6B, the locking rotor 40 has been rotated by the trigger guard “G” into a fully-locked position best shown in FIG. 6A. The lobe 46 has rotated into the space behind the trigger guard “G” forward of the trigger, and the solenoid plunger 34 has extended into a locked position against the shoulder 50. The locked position is thus maintained by the plunger 34 of the solenoid 32 bearing against the shoulder 50 of the locking rotor 40. An attempt to withdraw the firearm “F” from the above-described locking position is defeated by the lobe 46 of the locking rotor 40 that remains locked behind the trigger guard “G”.

[0045] Referring back to FIG. 3, the circuit board 22 is preferably a contactless circuit, such as a smart card, chip card, or integrated circuit card (ICC), and is credentialed and operatively connected to the solenoid 32. The battery 24 is preferably a lithium ion battery. It is anticipated that in the future operating principles of the circuit and battery may further develop, and it is the intention of this application to include in its scope such new developments as they may develop.

[0046] As is illustrated in FIGS. 7A and 7B, to unlock the locking rotor 40, an electronic “key”, for example a proximity tag 54 with a unique code is paired with the circuit board 22. When the tag 54 is moved into a predetermined proximity to the circuit 22, the circuit 22 energizes and releases the solenoid 32, which withdraws the plunger 34 from its position against the shoulder 50 of the locking rotor 40. The withdrawal of the plunger 34 does not itself unlock the firearm “F” by rotating the lobe 46 out from behind the trigger guard “G”. It merely permits the locking rotor 40 to rotate. Actual rotation of the locking rotor 40 is accomplished by the torsion spring 48 on which the locking rotor 40 is mounted. When permitted by the withdrawal of the plunger 34 from the shoulder 50, the torsion spring 48 rotates the locking rotor 40 counterclockwise, withdrawing the lobe 46 from behind the trigger guard “G” and returning the locking rotor 40 to the unlocked position of FIGS. 4A and 4B. This permits the firearm “F” to be extracted from the holster 10.

[0047] The tag 54 may be integrated into a wristband, ring, cufflink, watch or other wearable object capable of being moved into proximity with the circuit board 22. The locking assembly 20 and its associated parts bolt into the holster 10 in a manner similar to existing holster construction. The locking assembly 20 replaces the typical 1″×2″×1.5″ plastic spacer block commonly found in holsters where the handgun trigger guard “G” resides when the firearm “F” is properly holstered.

[0048] In the event of a battery or circuit failure, the firearm “F” may be unlocked manually. This is accomplished by providing a secondary, manual release 60 shown in FIGS. 4B, 5B, 6B and 7B. Release 60 can be manually operated by pushing on a button 62, which urges a lever 64 clockwise against the plunger spring 36, retracting it from its position against the plunger 34 and allowing the plunger 34 to retract. In the same manner as described above, the torsion spring 48 is allowed to rotate the locking rotor 40 counterclockwise, withdrawing the lobe 46 from behind the trigger guard “G”.

[0049] The locking assembly 20 may optionally be provided with an unlocked indicator tone, low battery light/indicator, spare battery compartment or other optional features.

[0050] A firearm safety lock is described above. Various details of the invention may be changed without departing from its scope. Furthermore, the foregoing description of the preferred embodiment of the invention and the best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation—the invention being defined by the claims.
