Abstract
A firearm combination safety lock is disclosed. The safety lock includes a plurality of independently actuatable members, which in the preferred embodiment, are four push button switches connected to an electronic circuit. The electronic circuit compares the sequence in which the buttons are pushed and will operate an interlock means when the sequence matches a predetermined sequence. The push buttons are preferably provided in the finger grip of the handle of the firearm.
Claims4
In a firearm including a handle, a barrel connected to the handle, and a firing mechanism, a safety device comprising:
- a plurality of independently actuatable members;
- electronic circuit means for determining whether the sequence in which said members are actuated is a predetermined sequence;
- and
- interlock means, operated by said determining means only when said members are actuated in said predetermined sequence, for preventing the operation of said firing mechanism, and hence of said firearm, unless said members are so actuated, said actuatable members comprising at least three electrical switches;
- the handle of said firearm including a finger grip;
- and said firearm further comprising mounting means for mounting said switches in said finger grip of said handle.
In a firearm including a handle, a barrel connected to the handle, and a firing mechanism, a safety device comprising:
- a plurality of independently actuatable members;
- electronic circuit means for determining whether the sequence in which said members are actuated is a predetermined sequence;
- and
- interlock means operated by said determining means only when said members are actuated in said predetermined sequence for preventing the operation of said firing mechanism, and hence of said firearm, unless said members are so actuated, said firing mechanism including a trigger which is movable between an inoperative position wherein the firearm cannot be fired and an operative position wherein said firearm can be fired, and said interlock means controlling the movement of said trigger between said inoperative and operative positions, said trigger being recessed into the firearm in the inoperative position thereof.
In a firearm including a handle, a barrel connected to the handle, and a firing mechanism, a safety device comprising:
- a plurality of independently actuatable members;
- means for determining whether the sequence in which said members are actuated is a predetermined sequence;
- and
- interlock means, operated by said predetermined sequence, for preventing the operation of said firing mechanism, and hence of said firearm, unless said members are so actuated, said actuatable members comprising at least three push buttons;
- the handle of said firearm including a finger grip;
- and said firearm further comprising mounting means for mounting said push buttons in said finger grip of said handle.
