Abstract

A latching device for releasibly locking together the two zipper pulls on aouble zipper type case includes a frame, a rotatable key barrel projecting from the frame for being received in respective openings in the zipper pulls, a latch member pivotally connected to the frame for movement between a lowered position overlying the frame and a raised position, the latch member having an opening therein for receiving the end of the key barrel when the latch member is in lowered position, and a key-actuatable bolt member supported below the key barrel for sliding movement between the locking and unlocking positions to releasibly lock the latch member in lowered position. The frame is mounted at one end of an elongated mounting plate having its other end constructed to engage a rigid reinforcing member of the case.

Claims

1. A latching device for releasably locking therein an element having an opening therein, the latching device comprising a frame, key-receiving means having an opening for receiving a key projecting from the frame, the key-receiving means being dimensioned to be received by the opening in the element, a latch member mounted on the frame for movement between a first position overlying the key-receiving means and a second position removed from the key-receiving means, the latch member in the first position being cooperable with the key-receiving means for preventing removal of the element from the key-receiving means, and locking means actuatable by a key inserted in the opening in the key-receiving means for movement between locking and unlocking positions, the locking means being cooperable with means provided by the latch member for releasably locking the latch member in the first position when the locking means is in locking position.

2. A latching device as set forth in claim 1, wherein the key-receiving means comprises a rotatable key barrel.

3. A latching device as set forth in claim 1, wherein the locking means comprises a bolt member supported for sliding movement between the locking and unlocking positions.

4. A latching device as set forth in claim 1, wherein the latch member is supported for pivotal movement between the first and second positions.

5. A latching device as set forth in claim 4, wherein the locking means comprises a bolt member supported below the key-receiving means for sliding movement between the locking and unlocking positions.

6. A latching device as set forth in claim 5, wherein the key-receiving means comprises a key barrel supported for rotation in an opening in the frame, the locking means being supported for sliding movement below the key barrel.

7. A latching device as set forth in claim 5, further comprising a leaf spring for resiliently maintaining the latch member in the first and second positions and for resiliently maintaining the bolt member in the locking and unlocking positions.

8. A latching device as set forth in claim 4, wherein an end portion of the key-receiving means is received in the opening in the latch member when the latch member is in the first position.

9. A latching device as set forth in claim 1, wherein the element having the opening therein is an apertured pull of a slider, and there are a pair of sliders on a zippered container to be locked together, and wherein the latching device further comprises mounting means for mounting the frame on the container.

10. A latching device as set forth in claim 9, wherein the mounting means comprises attachment means for connecting the frame to a rigid member provided by the container.

11. A latching device as set forth in claim 10, wherein the attachment means has means for enabling adjustment of the position of the frame relative to the rigid member provided by the container.

12. A latching device as set forth in claim 9, wherein the mounting means comprises a mounting plate having means at one end for connection to the container, and having its other end attached to the frame;

and wherein the locking means comprises a bolt member supported by said other end of the mounting plate for sliding movement between the locking and unlocking positions.

13. A latching device as set forth in claim 12, further comprising a leaf spring for biasing the bolt member against said other end of the mounting plate, and wherein the bolt member and said other end of the mounting plate have cooperable means for resiliently maintaining the bolt member in the locking and unlocking positions under the urging of the leaf spring.

14. A latching device as set forth in claim 13, wherein the latch member is supported for pivotal movement between the first and second positions, and wherein the leaf spring provides means for releasably maintaining the latch member in the first and second positions.

15. A latching device as set forth in claim 12, wherein the key-receiving means comprises a key barrel, and wherein the key barrel is supported for rotation in an opening in the frame by means provided by said other end of the mounting plate.

16. A latching device as set forth in claim 14, wherein the key-receiving means comprises a key barrel, and wherein the key barrel is supported for rotation in an opening in the frame by means provided by said other end of the mounting plate.
