Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 illustrates a gun safety lock in accordance with the present invention when it is used with a pistol.

(2) FIGS. 2-4 illustrate a turnbuckle type of mechanism in accordance with the present invention, with FIG. 2 illustrating a turnbuckle body in cross section connected to a locking device which is shown generally, while FIGS. 3 and 4 illustrate, respectively, in cross section, the breach and barrel portions of the turnbuckle device.

DETAILED DESCRIPTION OF THE INVENTION

(3) In accordance with the present invention, a gun safety lock is quickly secured and unsecured to a gun when a locking device is in an unlocked position, whereas the device cannot be altered when the combination lock is in a locked position.

(4) The gun safety lock utilizes a turnbuckle type of mechanism to snugly secure its two ends to the breach and the barrel of a gun, so that the gun cannot be loaded or fired when the gun safety lock is locked in place, and it is especially well-suited for use with handguns or pistols in which one size of a gun safety lock can fit many different types, makes and calibers of handguns or pistols. The present invention can also be utilized with rifles and shotguns, in which case different lengths of the gun safety lock can be used to accommodate different lengths of barrels and sizes of guns.

(5) In accordance with an especially preferred embodiment of the present invention, a gun safety lock 1 utilizes a turnbuckle type of mechanism 10 which works by adjusting tension between its two ends by rotating the frame, which causes both of its ends to be screwed in or out simultaneously (although it is less desirable, the turnbuckle type of mechanism could be altered so that rotation of its frame only causes one of its ends to be screwed in or out and still be within the scope of the present invention). In a secured, closed, position, the two ends fit snugly in, respectively, the breach and barrel of the gun, whereas in an open position, the two ends can be removed from the breach and barrel of the gun. As noted in Wikipedia, under turnbuckle (en.wikipedia.org/wiki/Turnbuckle), the disclosure of which is specifically incorporated herein by reference, a turnbuckle normally has two threaded bolts, one screwed into each end of a small metal frame, one with a left-hand thread and the other with a right-hand thread. Tension can be adjusted by rotating the frame, which causes both bolts to be screwed in or out simultaneously.

(6) In a preferred embodiment of the present invention, as illustrated in FIG. 2, a turnbuckle mechanism 10 has a body 11, a breach portion 20 and a barrel portion 30. Body 11 has two internal screw threads 12 and 13 used to connect two threaded rods 21 and 31, respectively, one configured with a left-hand thread and the other with a right-hand thread. Threaded rod 21 has threads 22 and is configured with a breach arm 23 in a generally u-shape configuration which ends with a breach end 24 that is configured so that it can be placed into a breach 51 of a gun 50 (as is generally illustrated in FIG. 1) and, in an especially preferred embodiment, has a frustoconical shape configured to accommodate different sized breaches of different guns. Threaded rod 31 has threads 32 and is configured with a barrel arm 33 in a generally u-shape configuration which ends with a barrel end 34 that is configured so that it can be placed into a barrel 52 of a gun 50 (as is generally illustrated in FIG. 1) and, in an especially preferred embodiment, has a frustoconical shape configured to accommodate different sized barrels of different guns. It is especially preferred that body 11, threaded rods 21 and 31, threads 22 and 32, breach arm 23 and barrel arm 33, and breach end 24 and barrel end 34 be comprised of metal (e.g., stainless steel) or other strong and rigid composites, or case-hardened metals, so that the turnbuckle mechanism cannot easily be breached or cut. Breach end 24 and barrel end 34 are preferably configured with breach and barrel protective elements 25 and 35, respectively, which are configured to prevent metal to metal contact and damage to either breach 51 or barrel 52. Protective elements 25 and 35 can be a coating, a molded part or a part slipped over breach end 24 and barrel end 34 and can be fabricated, for example, from a polymer such as polyurethane, silicone, EPDM (ethylene propylene diene terpolymer), neoprene and natural rubber.

(7) In accordance with the present invention, a locking device 40 is used to secure turnbuckle mechanism 10 from removing breach end 24 from breach 51 and barrel end 34 from barrel 52 when the locking device is in a locked position. In one especially preferred embodiment, locking device 40 is a combination lock, as is illustrated generally in FIG. 1. As noted in Wikipedia at https://en.wikipedia.org/wiki/Combination_lock, the disclosure of which is specifically incorporated herein by reference, a combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock, and some designs of such locks include multiple-dial locks, single-dial locks and rotary locks. In another especially preferred embodiment, locking device 40 is a key lock affixed to body 11 which allows movement of threaded rod 21 or 31 when it is in an unlocked position but prevents such movement when it is in a locked position. In one especially preferred embodiment, the locking device can be a multi cylinder lock. Additional locking devices, such as electronic or biometric locking devices, can also be used.

(8) It is also especially preferred, whatever locking device is used, that the locking device itself be protected with metal (e.g., stainless steel) or other strong and rigid composites, or case-hardened metals, so that the locking device cannot easily be breached or cut, and it is especially preferred that locking device be made integral with turnbuckle mechanism 10, as is illustrated in FIG. 1. Accordingly, for example, locking device 40 can be made integral with, and be a part of, body 11, threaded rod 21 or threaded rod 31.

(9) It should be noted that locks can eventually be figured out, or picked, but such devices provide sufficient security to prevent immediate use of the gun in most circumstances, such as when it might be acquired by a criminal element in a home invasion type of scenario, thus preventing easy use of the gun against its owner, while still providing sufficient security to guard against accidental unlocking by juveniles and the like, which is a problem with some of the flimsier gun locks which have been placed into the stream of commerce. Also, as opposed to trigger locks, the present invention helps to prevent against accidental discharge of a loaded gun. Moreover, when a safety lock in accordance with the present invention is made of a secure turnbuckle mechanism that cannot easily be cut, and locking device 40 is made integral therewith, the result is an improved, more secure, yet readily usable gun safety lock which can save lives, and one which can be used in many different makes and types of guns, rather than being designed solely for use with a particular gun.

(10) While the invention has been described herein with reference to certain preferred embodiments, those embodiments have been presented by way of example only, and not to limit the scope of the invention. Additional embodiments and further modifications are also possible in alternative embodiments that will be obvious to those skilled in the art having the benefit of this detailed description.

(11) Accordingly, still further changes and modifications in the actual concepts described herein can readily be made without departing from the spirit and scope of the disclosed inventions.
