Abstract

A security and locking mechanism for the double door type security safe, vault or bunker wherein the double door can be manufactured by conventional structure or the through use of a plurality of modular panels, the locking and securing mechanism comprising a pair of longitudinal, vertically oriented bolt channels secured to the inner surface of each of the double doors proximate the vertical edges of the double doors, the bolt channels proximate the hinged edge of each door having a plurality of passive locking rods extending there through and extending beyond the hinged edge of the door, the second longitudinal bolt channels on the doors having a plurality of apertures through vertical web members, are secured proximate the seam formed between the double doors, one of the bolt channels being positioned such that it overlaps the seam formed between the two doors, the active locking and securing mechanism comprising a plurality of horizontally oriented throw bolts passing through the longitudinal bolt channels proximate the seam, the plurality of horizontal throw bolts supported by a throw bolt support bar vertically oriented, with at least one of the horizontally oriented throw bolts having a toothed gear formed thereon in communication with a round gear secured to the inner surface of the door, the round gear in communication with a throw bolt wheel located on the outer surface of the door, the throw bolt wheel activatable by a keypad combination member.

Claims

1. A security and locking mechanism for a double door utilized in a security safe, vault or bunker, said security and locking mechanism comprising:

a security safe, vault or bunker having a plurality of interconnected side walls, a top wall interconnected with said side walls, and a bottom wall interconnected with said side walls, there being formed on one of said side walls an outward opening double door for ingress and egress into said security safe, vault or bunker, said double door being secured by a security and locking mechanism, said double door comprising a first door and a second door hinged to one of said side walls along one vertical longitudinal edge, an opposing vertical longitudinal edge of said first door and said second door in abutting relationship to each other when in a closed position forming a seam between said doors, said doors having an interior surface and an exterior surface;

a keypad or combination member mounted on said exterior surface of said first door;

a rotatable handle member mounted on said exterior on said first door, said rotatable handle member in communication with a rotatable gear member mounted on a common spindle with said rotatable handle member on said interior surface of said first door, said rotatable gear member in communication with a linear gear member mounted on said security and locking mechanism on said interior of said first door, said rotatable handle member rotatable in response to correct combination being entered on said keypad or said combination member;

a lever handle member mounted on the exterior of one of said first or second doors for the hingeable opening and closing of said double door;

a plurality of vertically oriented first bolt channels secured to said interior surface of said first and second doors, proximate said hinged vertical longitudinal edge, said bolt channels proximate said hinged vertical longitudinal edge having fixedly secured thereto a plurality of horizontally disposed fixed security bolts extending in a plane parallel to said door and extending beyond said hinged vertical longitudinal edge so as to overlap an inner wall of said security safe, vault or bunker;

a second bolt channel fixedly vertically oriented and secured to the inner surface of said second door proximate said seam formed by said first and second doors when in a closed position, said second bolt channel having a plurality of horizontal aligned apertures there through;

a third bolt channel vertically oriented and fixably secured to the inner surface of said first door, said third bolt channel overlapping said seam formed between said first and second doors, said third bolt channel having a plurality of horizontal aligned apertures there through in alignment with said apertures in said second bolt channel;

a horizontally movable throw bolt support bar having a vertical orientation and positioned between said first bolt channel and said third bolt channel on said first door, and having a plurality of throw bolts fixedly mounted thereon and extending to one side thereof horizontally, said throw bolts alignable with apertures formed in said second bolt channel and said third bolt channel mounted proximate said seam of said first and second doors, one of said throw bolts extending to an opposing side of said throw bolt support bar and engageable in an alignable aperture formed in said first bolt channel proximate said hinged vertical edge on said first door;

one of said throw bolts having secured thereon, said linear gear member in communication with said rotatable gear for movement of said throw bolt support bar and secured throw bolts from a closed locked position wherein said throw bolts extend through said second and third bolt channels to an open position wherein said throw bolts are withdrawn such that said throw bolts do not extend beyond said seam of said doors into engagement with said second bolt channel.

2. A security and locking mechanism in accordance with claim 1 wherein said first bolt channels are generally C-shaped in cross section having a planar web member having a plurality of apertures there through for the receipt of a securing means for securing said first bolt channels to said interior surface of said first and second doors, said planar web member having upstanding flanges on longitudinal edges thereof extending on the same side of the planar web member.

3. A security and locking mechanism in accordance with claim 1 wherein said second and third bolt channels are generally C-shaped in cross section having a planar web member having a plurality of apertures therethrough for the receipt of a securing means for securing said bolt channel to said interior surface of said doors, said planar web member having upstanding flanges on longitudinal edges thereof extending to the same side of the planar web member, said upstanding flanges having a plurality of aligned apertures therethrough for the slidable receipt of said horizontally movable throw bolts.

4. A security and locking mechanism in accordance with claim 3 wherein the diameter of said apertures in said bolt channels for receipt of said horizontally movable throw bolts is equal to the diameter of said throw bolts.

5. The security and locking mechanism in accordance with claim 1 wherein said vertically oriented second bolt channel proximate said seam between said first and second doors and said third bolt channel overlapping said seam between said first and second doors provides for four contact points for said movable throw bolts when in a locked and secured position.

6. The security and locking mechanism in accordance with claim 5 wherein the addition of additional second bolt channels proximate said second bolt channel proximate said seam between said first and second doors increases the number of said contact points for said horizontally movable throw bolts for securing said doors in a closed and locked position.

7. The security and locking mechanism in accordance with claim 1 wherein first and second doors comprising said double door for said security safe, vault or bunker, are of conventional one piece construction.

8. The security and locking mechanism in accordance with claim 1 wherein first and second doors comprising said double door for said security safe, vault or bunker, are of modular construction formed by a series of panels whose integrity is maintained by said bolt channels.
