Abstract

A magnetic gate latch device to secure a gate in a locked position to a fence or other barrier to close or block a portal formed therein comprising a latch assembly including a lower latch pin coupled to an upper latch pin actuator by an intermediate interconnecting element mounted to the fence or other barrier adjacent the portal wherein the lower latch pin is normally biased in upper or unlocked position and a keeper assembly including a keeper base affixed to the gate and a keeper arm extending outwardly therefrom having a latch pin recess formed therein with a latch pin positioner comprising a vertically disposed magnet disposed adjacent the latch pin recess such that when the gate is closed the vertically disposed magnet of the latch pin positioner moves the lower latch pin, intermediate interconnecting element and upper latch pin from the normally biased upper or unlocked position to a lower or locked position drawing the latch pin into the latch pin recess against the force of the bias and when as the upper latch pin actuator is moved upwardly the intermediate interconnecting element and the lower latch pin are moved upwardly withdrawing the lower latch pin from the latch pin recess to permit the gate to be opened as the bias maintains the lower latch pin in upper or unlocked position.

Claims

1. A gate latch device to secure a gate in a locked position to a fence or other barrier to close or block a portal formed therein comprising a latch assembly including a lower latch pin coupled to an upper latch pin actuator by an intermediate interconnecting element mounted to the fence or other barrier adjacent the portal wherein said lower latch pin is normally biased in upper or unlocked position and a keeper assembly including a keeper base affixed to the gate and a keeper arm extending outwardly therefrom having a latch pin recess formed therein with a latch pin positioner disposed adjacent said latch pin recess such that when the gate is closed said latch pin positioner moves said lower latch pin, said intermediate interconnecting element and said upper latch pin actuator from the normally biased upper or unlocked position to a lower or locked position drawing said latch pin into the latch pin recess against the force of said bias and when as said upper latch pin actuator is moved upwardly said intermediate interconnecting element and said lower latch pin are moved upwardly withdrawing said lower latch pin from said latch pin recess to permit the gate to be opened as said bias maintains said lower latch pin in upper or unlocked position.

2. The gate latch device of claim 1 wherein said latch assembly further includes an upper lock housing, an intermediate housing and a lower latch housing.

3. The gate latch device of claim 2 wherein a latch position indicator is disposed on said upper lock housing to provide a visual indication of the position of said lower latch pin relative to said keeper assembly to indicate when said latch assembly is in the upper or unlocked position and the lower or locked position.

4. The gate latch device of claim 3 wherein the latch position indicator comprises a colored sleeve extending upwardly from said upper lock housing such that said colored sleeve is disposed entirely within a recess formed in said upper latch pin actuator to indicate that said lower latch pin is in the lower or locked position when the lower periphery of said upper latch pin actuator engages a portion of said upper lock housing.

5. The gate latch device of claim 4 wherein said upper latch pin actuator comprises an actuator pull knob having an arcuate outer surface coupled to the upper portion of said intermediate interconnecting assembly.

6. The gate latch device of claim 2 wherein said lower latch housing comprises a lower latch base including an outer recess configured to receive the outer position of said keeper assembly when the gate is in the locked position.

7. The gate latch device of claim 2 wherein said keeper assembly comprises a latch base attached to the gate having a latch arm extending outwardly therefrom.

8. The gate latch device of claim 7 wherein said latch arm comprises a latch pin receptacle including a latch pin recess formed therein to receive said lower latch pin when in the lower or locked position.

9. The gate latch device of claim 8 wherein said latch pin positioner comprises a magnet disposed adjacent said latch pin.

10. The gate latch device of claim 9 wherein said magnet is disposed laterally relative to said latch pin recess.

11. The gate latch device of claim 10 wherein the upper peripheral edge of the latch pin receptacle is slanted inwardly to form a moisture run-off surface below said lower latch housing.

12. The gate latch device of claim 11 further including at least one drain aperture formed in said latch pin receptacle.

13. The gate latch device of claim 10 further including at least one drain aperture formed in said latch pin receptacle.

14. The gate latch device of claim 7 wherein said latch base and said latch arm are laterally adjustable relative to each other.

15. The gate latch device of claim 14 wherein said latch base and said latch arm are laterally adjustable relative to each other by an externally threaded member that engages corresponding threads formed on said latch base and said latch arm.

16. The gate latch device of claim 7 wherein said latch base includes a handle formed on the front portion thereof.

17. The gate latch device of claim 16 wherein said latch base further includes a mounting bracket having a substantially L-shaped configuration to affix said keeper assembly to the gate.

18. The gate latch device of claim 7 wherein said latch base includes a mounting bracket having a substantially L-shaped configuration to affix said keeper assembly to the gate.

19. The gate latch device of claim 18 wherein said latch base and said latch arm are laterally adjustable relative to each other.

20. The gate latch device of claim 19 wherein said latch base and said latch arm are laterally adjustable relative to each other by an externally threaded member that engages corresponding threads formed on said latch base and said latch arm.
