[0001] This invention relates to securing of a firearm to prevent use thereof and more specifically to safety devices that attach to the firearm in a manner to prevent loading or firing of the weapon. The new safety device incorporates a shackle type lock inserted through a weapon magazine, open breech or open cylinder space to inhibit placing a cartridge in the chamber, loading a magazine or cylinder or firing pin contact with a cartridge for a firearm.
[0002] Firearm safety is a major concern. Although most weapons are manufactured with stringent standards and built-in safety mechanisms, they are not designed to prevent unintentional, accidental or negligent discharge in the case of careless or unauthorized use.
[0003] There are numerous add on firearm safety devices currently in use. One of the more common methods to prevent use of a firearm is use of trigger lock or trigger block devices. These devices are designed to lock or block the trigger of a firearm. However, any possible movement of the trigger may cause a discharge. Additionally, if a cartridge is in the chamber the weapon may discharge for various reasons such as inertia firing, dropping of the weapon, a sharp blow to the trigger lock device, etc. Experience has shown that many of these devices can be defeated by use of common tools and instances where children have done this exists.
[0004] Other safety devices such as cable locks and lever straps are easily defeated by cutting. Barrel plugs or chamber inserts are specific to a specific model weapon, complex and expensive, and most are easily disabled.
[0005] Devices attached to firearms that inhibit loading a cartridge or closing a breech bolt are known in the art. Two examples are U.S. Pat. Nos. 4,654,992, issued Apr. 7, 1987 and 5,419,069, issued May 30, 1995. The U.S. Pat. No. 4,654,992 patent discloses a device, which mounts to a shotgun trigger guard and includes a fingerplate inserted into the firearm open breech and locking by a tumbler lock device. This device prevents loading of a cartridge and closing of the breech bolt. However, its structure must be specifically designed for each weapon. Also the fingerplate is susceptible to tampering such as cutting or bending.
[0006] The U.S. Pat. No. 5,419,069 patent discloses a firearm locking mechanism, which is inserted into the open breech of the weapon. It depends on securing thereof to a magazine loaded in the weapon. A tumbler type lock secures loading of the firearm chamber, closing the breech bolt and firing pin contact with a cartridge. Again as discussed above the mechanism is specific for a particular model weapon. It is also susceptible to tampering due to the engagement with the loaded magazine.
[0007] As can be seen, there is a need for a simple, tamper resistant device and method to secure a wide variety of firearms to prevent use thereof.
[0008] One object of the present invention is improved securing of firearms to prevent unauthorized use or accidental firing of the weapon. Another object is accommodation of a variety of forms and types of firearms using a single form factor for securing or locking. A further object is a tamper resistant, economical and simple to use securing device. Yet another object is provision for attachment of other securing elements such as chains, cables and the like to the invention.
[0009] These and other features, aspects and advantages of the present invention will become better, understood with reference to the following drawings, description and claims.

[0015] The following detailed description is the best currently contemplated modes for carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention.
[0016] A case hardened shackle lock with a shackle lockable with a lock body is adjustable in length to accommodate a wide variety of forms and types of firearms. One leg of the shackle is inserted through a firearm magazine well and open breech or a revolver cylinder space and then the shackle is slidably engaged with the lock mechanism. This inhibits the insertion of cartridges in a weapon, the closing of the breech bolt of a weapon, and the impact of the firing pin on a cartridge.
