Abstract

A gate has an expandable barrier and a horizontal rail located at a top of the barrier. A post may be coupled to the barrier and may have a portion extending above the horizontal rail. A lock is movably coupled to the post above the rail to provide for the locking and unlocking of the gate.

Claims

1. A gate, comprising:

an expandable barrier having a top end, a bottom end, and a horizontal rail forming an uppermost surface of the barrier, the horizontal rail having an uppermost top horizontal edge;

a first and second vertical end post, wherein the top end of the expandable barrier is adjacent to a top end of the first vertical end post and the bottom end of the expandable barrier is adjacent to a bottom end of the first vertical end post; and

an entire handle-lock module including a locking member is located entirely above the uppermost top horizontal edge of the horizontal rail in all operating positions of the gate and biased upwardly for controlling at least one of locking and unlocking the gate.

2. The gate according to claim 1, wherein the locking member is movable with the handle-lock module and is also located above the uppermost top horizontal edge of the horizontal rail.

3. The gate according to claim 2, wherein the horizontal rail is an adjustable length horizontal rail;

wherein the handle-lock module further having a biasing member for urging the handle-lock module to a locking position, and the handle-lock module being located above the adjustable length horizontal rail.

4. The gate according to claim 3, wherein the locking member further comprises an upwardly extending protrusion.

5. The gate according to claim 3, wherein the handle-lock module further includes laterally mounted finger-engageable buttons provided on opposing sides of the handle-locking module and configured for simultaneous depression to control the unlocking operation of the gate.

6. The gate according to claim 5, wherein the laterally mounted finger-engageable buttons are nested within the handle-lock module.

7. The gate according to claim 6, wherein each of the finger-engageable buttons includes an integrally molded spring member, each spring member being configured to bias the finger-engageable button of another lock control member in an outward direction from each other.

8. The gate according to claim 3, wherein the first vertical end post is coupled to the expandable barrier at one lateral end and has a portion extending above the adjustable length horizontal rail;

and wherein the handle-lock module is slidably movable vertically along a length of the first vertical end post.

9. The gate according to claim 8, wherein the handle-lock module includes an opening configured to receive a portion of the first vertical end post therein.

10. The gate according to claim 8, wherein the biasing member is coupled to the top of the first vertical end post and coupled to the handle-lock module.

11. The gate according to claim 8, wherein the handle-lock module further comprises laterally mounted finger-engageable elements provided on opposing sides of the handle-lock module, wherein the handle-lock module and included finger-engageable elements are vertically movable relative to a top end of the first vertical end post when the finger-engageable elements are depressed;

and wherein at least one of the finger-engageable elements includes a spring member.

12. The gate according to claim 3, wherein a bottom of the handle-lock module is located at least 1.0 inch above the expandable barrier.

13. The gate according to claim 12, wherein the handle-lock module is configured to vertically travel at least ½

inch to affect the locking and unlocking of the gate.

14. The gate according to claim 3, further including a pin disposed one side of the expandable barrier, the pin including an extension leg being biased to provide a snap-fit engagement with a wall mount.

15. The gate according to claim 14, wherein the extension leg of the mounting pin includes a tab at a distal end enabling the extension leg to be released from the wall mount.

16. The gate according to claim 3, wherein at least one of the first or second vertical end posts is disposed at a lateral end of the expandable barrier;

wherein the adjustable length horizontal rail is slidably coupled to the first vertical end post to vertically slide along a length of the first vertical end post during an expansion or a retraction of the expandable barrier.

17. The gate according to claim 16, further comprising a tubular coupling member for providing the slidable coupling to the post.

18. The gate according to claim 16, wherein a vertical distance between the handle-lock module and the adjustable length horizontal rail changes during an expansion or retraction of the expandable barrier.

19. A gate comprising:

an expandable barrier with a horizontal rail forming an uppermost surface of the barrier, the barrier having a top end, a bottom end, a first end and a second end;

a downwardly extending docking pin disposed at the first end of the barrier;

a first vertical rail provided at the first end of the barrier and a second vertical rail provided at the second end of the barrier, wherein the top end of the expandable barrier is adjacent to a top end of the first vertical rail and the bottom end of the expandable barrier is adjacent to a bottom end of the first vertical rail; and

an upwardly extending locking pin included as part of a handle-lock body, the handle-lock body disposed over the horizontal rail at all operating positions of the gate, and being coaxially aligned with a center axis of the first vertical rail, the upwardly extending locking pin being located above and coaxial with the downwardly extending docking pin, wherein the locking pin is biased in a direction away from the docking pin to maintain the gate in a locked state.

20. The gate according to claim 19, wherein the locking pin and the docking pin each have a circular cross-section.

21. The gate according to claim 19, wherein the second end includes two vertically spaced, downwardly extending hinge pins.

22. The gate according to claim 21, wherein the hinge pins on the second end are circular in cross-section.

23. The gate according to claim 21, wherein at least one of the hinge pins on the second end is configured for snap-fit engagement with a mount and includes an extension leg being biased to provide a snap-fit engagement with the mount, the extension leg including a tab at a distal end enabling the extension leg to be released from the mount.

24. A gate, comprising:

an expandable barrier, the expandable barrier having a horizontal rail;

a first and second vertical rail; and

a gate-lock having a housing and a recess which receives a top end of the first vertical rail, said housing and recess being telescopically coupled to the first vertical rail for relative movement to control at least one of locking and unlocking of the gate;

wherein the gate-lock is movable between locked and unlocked positions, such that a locking member of said gate-lock moves substantially parallel relative to the first vertical rail in order to lock and unlock the gate.

25. The gate according to claim 24, wherein the horizontal rail is an adjustable length horizontal rail.

26. The gate according to claim 25, wherein a bottom of the gate-lock is located at least 1.0 inch above the adjustable length horizontal rail when the gate-lock is in its locked position.

27. The gate according to claim 25, wherein a top portion of the gate-lock is located 6.0 inches above the adjustable length horizontal rail.

28. The gate according to claim 25, wherein the gate-lock has a vertical range of travel of 3 inches.

29. The gate according to claim 24, further comprising a biasing device for urging the gate-lock in an upward direction to extend the gate-lock further along the first vertical rail, and away from the horizontal rail.
