Abstract
A firing pin locking mechanism that can be used on firearms. Controlled by a key, the internal locking device blocks all movement of the firing pin assembly striker, rendering the firing arm from discharging. The mechanism primarily comprises a spacer sleeve and a slide cover key plate. Utilizing the key, the authorized user has the ability to set the firearm in a “unlocked” or “locked” mode, even while in a holster. The internal locking mechanism is utilized as a means to prevent the movement of a firearm's firing pin assembly when activated by the trigger mechanism, regardless of the status of the firearm. The present invention is primarily utilized with semi-automatic firearms that have an enclosed striker assembly.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a turn-key locking mechanism for weapons, and more particularly, to an internal locking mechanism for firearms.




2. Description of the Related Art




Weapons and firearms are very dangerous. Many firearm locking mechanisms have been introduced to reduce the possibility of injury when unauthorized users discharge them, especially children. Presently, most firearms are manufactured with built-in safety mechanisms for triggers and firing pin assembles, as well as mechanisms to prevent discharge in the event of an accidental drop. However, there is a need to place firearms in an “unlocked” or “locked” mode notwithstanding the firearm in cocked or fired position. This would allow the authorized user to activate the firearm to “unlock” or deactivate the firearm to “locked” mode, even while set in a holster. There is a need for a practical and inexpensive assembly that can be incorporated into firearms without major structural changes to lock a firearm irrespective of the firearm status.




There are no similar internal locking mechanisms to the best of applicant's knowledge, that may be utilized to lock a firearm regardless of the firearm status, with a key that does not require movement of a firearm slide.




SUMMARY OF THE INVENTION




It is one of the main objects of the present invention to provide an internal locking mechanism for firearms to lock the firing mechanism, regardless of the firearm status.




It is another object of the present invention to provide a key to set the firearm in a “unlocked” or “locked” mode even if the firearm is secured in a holster.




It is still another object of this invention to provide a locking mechanism for firearms that includes a key, an internal locking device and a slide cover key plate.




It is yet another object of this invention to provide a locking mechanism for firearms in which the internal locking mechanism is utilized as a means to prevent the movement of a firearm firing pin assembly when activated by the trigger mechanism, regardless of the firearm status.




It is still another object of the present invention to provide an internal locking mechanism utilized with semi-automatic firearms that have an enclosed striker assembly.




It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.




Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
