DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to gun locks and more particularly to gun locks having a split casing for enclosing a trigger and trigger guard associated therewith, and means to secure the gun lock and its associated gun to a fixture to prevent unauthorized removal of the gun.
BACKGROUND OF THE INVENTION
Gun locks have frequently included just a single lock which secures the gun to a rack which upon being unlocked renders the gun ready for use. Still further, such locks cannot be employed once the lock has been removed from the rack, to inhibit use of the gun.
British Patent 968669 discloses a gun lock which fits around the trigger guard and prevents access to the trigger. The particular lock is not intended for securing to a wall or other structure. Similar comments also apply to the lock which is described in U.S. Pat. No. 3,624,945.
Disclosed in Australian Patent Application 85874/91 (U.S. Pat. No. 5,153,360) is 2 gun lock having trigger shields. The shields are held together by means of a bolt, access to which is prevented by a cylinder lock.
OBJECT OF THE INVENTION
It is the object of the present invention to overcome or substantially ameliorate the above disadvantages.
SUMMARY OF THE INVENTION
There is disclosed herein a gun lock for a gun having a trigger and trigger guard, said gun lock comprising: access thereto by being located on opposite sides of the trigger guard; engage the shield halves to prevent removal of the shield halves from a position enclosing the trigger; and prevent removal of the shackle member from the shield halves.
Preferably the shackle member which straddles the gun is adapted to engage a wall bracket; the wall bracket in turn being adapted to be secured to a wall or floor so that when the gun is secured thereto, unauthorised removal of the gun is inhibited.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein:
FIG. 1 is a schematic side elevation of a gun, gun lock and wall mounting bracket; and
FIG. 2A is a schematic parts exploded view of the gun lock of FIG. 1.
FIG. 2B is a detailed view of the shelve halves and wall bracket assembly.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In the accompanying drawings there is schematically depicted a gun lock 10 to surround the trigger and trigger guard of a gun 11. The lock 10 is also adapted to co-operate with a wall bracket 12 which is intended to be secured to a structure (such as a wall or floor).
The lock 10 includes a pair of shield halves 13 and 14 which are intended to be located on opposite sides of the trigger guard. The shield half 13 has a threaded shaft 15 and a projection 16 fixed thereto. The projection 16 and shaft 15 are rotatably mounted in the flange 34. The projection 16 has a shackle passage 17 which intersects with a further passage 18 which receives a lock assembly including a barrel 19. When the lock barrel 19 is located in the passage 18, the lock barrel partly protrudes into the shackle passage 17. More particularly, the lock barrel 19 is operable by means of a key to be retained in the projection 16. Upon operation of the key, the barrel can be removed or located in a position not intersecting with the passage 17. Preferably the barrel 19 is captively located within the passage 18, and has an eccentric projection which is movable to engage within the recess 27. The projection being eccentric with respect to the rotational axis of the barrel 19.
As a still further construction of the barrel 19 could include an end shaft portion with a "cut out" which when positioned adjacent the shackle member 23, permitted movement thereof. However upon rotation of the barrel 19, the shaft portion would enter the recess 27.
The shield half 14 includes a flange 33, which rotatably supports a projection 20 having a shackle passage 21. The projection 20 also has a threaded passage 22 to threadably engage the shaft 15. Accordingly upon engagement of the shaft 15 within t
