Abstract

A steel plate hasp is permanently fixedly attached to a door keeper bar, the bar for rotating about its longitudinal axis between door closed and open states. A casing has a plurality of walls forming a housing cavity in which the hasp is received through an opening in a housing wall with bolt seal shank apertures aligned in the hasp and housing. The casing may be permanently secured to the door by bolts or welds or may be selectively attached and removed from the hasp in a locked and unlocked state without fixed attachment to the door. A bolt seal has a shank with a head at one end wherein the head engages a housing wall and a locking body engages and locks to the shank other end and to a further housing wall. The shank between the head and lock body is fully enclosed by the housing and door to preclude access to the shank by tampering tools. The casing when secured to the hasp cooperates with the door to prevent the keeper bar from rotating open. The hasp rotates within the housing cavity of the permanent type casing. Other casing embodiments are disclosed for use with different latch hasps.

Claims

1. Locking and seal protection device for use with a rotating keeper bar for an enclosure door and a locking seal, the keeper bar for rotation to door open and locked states, the seal comprising a shank having opposing ends with locking means at one shank end and a locking body selectively locked to the shank at the opposing shank end, the device comprising:

a hasp having at least one seal shank receiving aperture, said hasp for being fixedly secured to and for rotation with said keeper bar to said open and locked states; and

a housing having a plurality of walls defining a cavity, a first housing wall having an opening for releaseably receiving said hasp and keeper bar in said cavity;

at least one second housing wall having an aperture juxtaposed with said received hasp at least one aperture for receiving said shank therethrough, the seal locking means and locking body for locking the received hasp to the housing second wall, said housing including means cooperating with said door for precluding rotation of the keeper bar in the seal locked state.

2. The device of claim 1 wherein said housing and hasp include means arranged so that said shank and hasp in the cavity between said locking means and said locking body are substantially enclosed to preclude access to the shank by tampering tools.

3. The device of claim 1 wherein said cavity is dimensioned to permit said hasp to rotate within said cavity as the keeper bar is rotated in the open state.

4. The device of claim 1 wherein said hasp is metal and the keeper bar is an elongated rod, said hasp for permanent attachment to the keeper bar.

5. The device of claim 1 wherein said housing at least one second wall comprises juxtaposed plate members forming housing opposing first and second side walls, said plate members each having a shank receiving aperture aligned with the received at least one hasp aperture.

6. The device of claim 5 wherein said locking means comprises a head secured to the shank, said housing including a further plate member in said cavity intermediate said housing opposing first and second side walls, said further plate member having a further aperture for receiving said shank therethrough aligned with said juxtaposed first and second opposing side wall apertures, said first wall aperture being enlarged relative to said further aperture for receiving said head therethrough so that the received head is in said cavity intermediate said first wall and further plate member.

7. The device of claim 5 wherein the locking body includes a tapered portion, the second side wall aperture being enlarged relative to the shank diameter to receive and engage said tapered portion.

8. The device of claim 6 wherein the further aperture has a tapered portion, said head including a tapered portion for engaging said further aperture tapered portion.

9. The device of claim 1 wherein the at least one second housing wall comprises first and second plate members each having a wall aperture for receiving the shank therethrough, the plurality of walls including a plurality of side walls, one of which forming said first housing wall, said first and second plate members for respectively enclosing the cavity sides, the second plate member aperture for receiving and engaging a portion of said locking body.

10. The device of claim 1 wherein the housing plurality of walls include opposing side walls, a rear wall and a front wall secured to the at least one second wall, the at least one second wall comprising a first side wall, a second side wall and an intermediate wall between the first and second side walls, the opening for the hasp being in the rear wall, the first, second and intermediate walls all having an aperture for receiving the shank.

11. The device of claim 1 including means for fixedly securing said housing to said door with said hasp received in said cavity.

12. The device of claim 10 wherein the locking means comprises a head, the head and a housing wall each having complementary tapered surfaces for receiving the head therein.

13. The device of claim 1 including a shield member secured to the housing for extending about the received locking body.

14. The device of claim 13 wherein said shield member comprises a rear wall and a pair of opposing lateral side walls.

15. The device of claim 14 including a further rear wall and fastening means extending from the rear walls for securing the housing to the door.

16. A device for locking an enclosure door keeper bar rotatable to door open and closed states in a closed locked state, the device for receiving a bolt seal having a shank, a head and a locking body for locking the keeper bar closed, the device comprising:

a hasp including at least one plate member leg, the leg having a shank receiving aperture, the leg for fixed attachment to the keeper bar;

a housing comprising front and rear walls, first and second opposing lateral side walls, top and bottom plate members defining a cavity for receiving said hasp and keeper bar, said walls and plate members for cooperating with said door for substantially enclosing said cavity, said first and second lateral side walls each having an aperture for receiving said shank, said head and locking body for securing the hasp to and between said first and second lateral side walls, said housing cooperating with said door to preclude rotation of the keeper bar in the locked state.

17. The device of claim 16 wherein the housing and the cavity are arranged so that the hasp and attached keeper bar are rotatable in said cavity.

18. The device of claim 16 including a shield member extending from the second lateral side wall.

19. The device of claim 16 including a further plate member overlying the first lateral side wall and secured to all said walls for forming a chamber therebetween, the further plate member having an aperture for passing the received head and shank therethrough, said first lateral side wall aperture for passing said shank and head therethrough so that the head in the received secured state is between the first lateral side wall and further plate member.

20. The device of claim 16 wherein the rear wall and top and bottom plate members extend from the second lateral side wall to partially surround the received locking body.
