Abstract

A barrier latch assembly having a housing including a first locking element, a second locking element, a trigger and a swing plate. The swing plate is coupled to the trigger and to the first and second locking elements. When the trigger is depressed, the swing plate pivots from an unlock position to a lock position over a rear side of the first and second locking element thereby blocking and preventing the first and second locking elements from being depressed inward.

First claim

The invention claimed is:

1. A latch assembly for a barrier gate, comprising:
a housing comprising:
a cavity formed by at least one retractable locking element and a pivoting locking element, the at least one retractable locking element being biased to an extended position;
a retractable trigger disposed within the cavity and adapted to depress when a first latch element of the barrier gate is received within the cavity, the trigger being biased to an extended position;
wherein when the trigger is depressed, at least one swing plate rotates causing the at least one retractable locking element to become fixed in its extended position and is prevented from being depressed, thereby securing the first latch element within the cavity.

2. The latch assembly of claim 1 , wherein the at least one retractable locking element comprises a pair of retractable locking elements.

3. The latch assembly of claim 2 , wherein the pair of retractable locking elements are positioned on opposing sides of the cavity.

4. The latch assembly of claim 2 , wherein the first latch element is secured within the cavity by the pair of retractable locking elements and the pivoting locking element.

5. The latch assembly of claim 4 , wherein the first latch element is adapted to be removed from the cavity by pivoting the pivoting locking element, and lifting the first latch element out from the cavity formed by the pair of retractable locking elements.

6. The latch assembly of claim 2 , wherein the at least one swing plate comprises a pair of swing plates which rotate, when the trigger is depressed, to block the retractable locking elements from being depressed from their extended positions.

7. The latch assembly of claim 1 , wherein the first latch element is adapted to depress the trigger and/or the at least one retractable locking element.

8. The latch assembly of claim 1 , further comprising at least one spring which is adapted to bias the at least one swing plate to a biased position, which allows the at least one retractable locking element to be depressed.

9. The latch assembly of claim 1 , further comprising at least one spring to bias the at least one retractable locking element to the extended position.

10. The latch assembly of claim 1 , further comprising a trigger spring to bias the trigger to the extended position.

11. The latch assembly of claim 1 , further comprising a second housing having a multi-positional rotating stopper element adapted to control the motion of a second latch element of the barrier gate.

12. The latch assembly of claim 11 , wherein the rotating stopper element is adapted to block the barrier gate from advancing past the rotating stopper element.

13. The latch assembly of claim 12 , wherein the rotating stopper element is adapted to permit movement of the barrier gate in at least one of: a first swinging direction in a first position; a second swinging direction in a second position; and the first and the second swinging directions in a third position.

14. A latch assembly for a barrier gate, comprising:
a housing comprising:
a cavity formed by a pair of retractable locking elements and a pivoting locking element, the retractable locking elements being biased to respective extended positions and positioned on opposing sides of the cavity;
a retractable trigger disposed within the cavity and adapted to depress when a first latch element of the barrier gate is received within the cavity, the trigger being biased to an extended position; and
a pair of swing plates which rotate to block the retractable locking elements from retracting from their extended positions when the trigger is depressed, thereby securing the first latch element within the cavity.

15. The latch assembly of claim 14 , further comprising a second housing having a multi-positional rotating stopper element adapted to control the motion of a second latch element of the barrier gate.

16. The latch assembly of claim 15 , wherein the rotating stopper element is adapted to block the barrier gate from advancing past the rotating stopper element.

17. The latch assembly of claim 16 , wherein the rotating stopper element is adapted to permit movement of the barrier gate in at least one of: a first swinging direction in a first position; a second swinging direction in a second position; and the first and the second swinging directions in a third position.

18. A latch assembly for a barrier gate, comprising:
a first housing comprising:
a cavity formed by a pair of retractable locking elements and a pivoting locking element, the retractable locking elements being biased to respective extended positions and positioned on opposing sides of the cavity;
a retractable trigger disposed within the cavity and adapted to depress when a first latch element of the barrier gate is received within the cavity, the trigger being biased to an extended position;
a pair of swing plates which rotate to block the retractable locking elements from retracting from their extended positions when the trigger is depressed, thereby securing the latch element within the cavity; and

a second housing comprising:
a multi-positional rotating stopper element adapted to control the motion of a second latch element of the barrier gate;
wherein the rotating stopper element is adapted to block the barrier gate from advancing past the rotating stopper element.

19. The latch assembly of claim 18 , wherein the first latch element is adapted to be removed from the cavity by pivoting the pivoting locking element, and lifting the first latch element our from the cavity formed by the pair of retractable locking elements.
