Security covering box

A protective box for providing a secure covering for a closure device disposed on a support surface, such as a lock, bolt, and the like, said protective box comprising:

• a housing having a rear wall and perimeter walls forwardly extending from said rear wall, said perimeter walls including at least two sidewalls and a bottom wall;
• an opening in said rear wall for providing access to the closure device to be protected;
• means for fastening said housing onto the support surface;
• cover means for closing said housing, said cover means including a cover member covering a front portion of said housing defined by said perimeter walls, said cover member including slide means for permitting said cover member to slide on said sidewalls between a closed position providing an enclosed area within said housing to protect the closure device, and an open position permitting access to the closure device;
• lock means coupled between said cover member and said housing for securely retaining said cover member in said closed position;
• said lock means including a lock disposed in said cover member for movement therewith, a latch coupled to said lock and operated thereby between a locked position and an unlocked position, and latching means disposed on said housing for engaging said latch in said locked position to prevent sliding of said cover member to said open position;
• said slide means including tongue and groove joints provided between side edges of said cover member and edge portions of said sidewalls of said housing, said cover member having an outside surface disposed in same plane as said edge portions of said sidewalls to prevent penetration of said enclosed area within said housing;
• said cover member including a rearwardly directed top wall, a seat provided along an upper edge of said rear wall of said housing and a lip provided at an outer edge of said top wall of said cover member, said lip and seat matingly engaging in said closed position to provide an overlap joint with an upper surface of said top wall being disposed in same plane as said upper edge of said rear wall to prevent penetration of said enclosed area within said housing;
• and
• said housing including holding means for holding said cover member in any selected raised position, said holding means including a forwardly directed spring loaded pin biased toward said cover member for bearing against an inside surface of said cover member to frictionally retard its sliding movement, said holding means permitting said cover member to be lowered to said closed position when a downward force greater than the frictional force of said spring loaded pin is applied on said cover member.
