Gate latch assembly

1. A magnetic gate latch assembly arranged to be mounted to either a gate or gate post and adapted to co-operate with a striker having a magnet mounted on the other of the gate or gate post to hold the gate closed, the gate latch assembly comprising:

a housing having a keeper arranged to receive the striker;

a latch mechanism disposed within the housing and having an internally mounted latching pin, the latching pin being movable between a latched condition where the latching pin is drawn into the striker by magnetic force provided by the magnet of the striker and an unlatched condition where the latching pin retracts into the housing;

an actuator for releasing said latching pin from the latched condition; and

at least one latch accessory in the form of a modular component removably engageable with at least one coupling portion of the housing to mount the modular component to the housing, the modular component houses an electronic sensor operable to sense a magnetic field of the latching pin through the housing to indicate a condition of the gate latch assembly via indirect sensing, the modular component being able to be removed from the housing during the normal operation of the latch mechanism.

2. A gate latch assembly as claimed in claim 1 , wherein the at least one latch accessory comprises a complementary coupling portion.

3. A gate latch assembly as claimed in claim 2 , wherein the at least one coupling portion is arranged to resiliently engage the at least one latch accessory in a snap fit arrangement.

4. A gate latch assembly as claimed in claim 3 , wherein the housing includes an elongate body extending between a first end and a second end.

5. A gate latch assembly as claimed in claim 4 , wherein the at least one coupling portion extends longitudinally along the elongate body.

6. A gate latch assembly as claimed in claim 5 , wherein the at least one coupling portion comprises one or more rails that extend along the elongate body.

7. A gate latch assembly as claimed in claim 6 , wherein the housing is in the form of an extruded section.

8. A gate latch assembly as claimed in claim 7 , wherein the housing further comprises a mounting structure mounted to the elongate body.

9. A gate latch assembly as claimed in claim 8 , wherein the mounting structure includes one of the at least one coupling portion.

10. A gate latch assembly as claimed in claim 9 , wherein a portion of the mounting structure is secured to an end of the elongate body.

11. A gate latch assembly as claimed in claim 10 , wherein the at least one coupling portion is able to receive the at least one latch accessory that is formed partly on the body and partly on the mounting structure.

12. A gate latch assembly according to claim 1 , wherein the sensed magnetic field of the latching pin is used to issue an alert when the striker is engaged with the keeper and the latch pin is not in a latched condition.

13. A method of assembling and operating the magnetic gate latch assembly according to claim 1 , the method comprising:

(a) providing the gate latch assembly including the housing containing at least a portion of the latch mechanism;

(b) mounting the at least one latch accessory to the housing,

(c) using the electronic sensor to sense a magnetic field of the latching pin of the latch mechanism through the housing, and if required

(d) removing the modular component from the housing

whereby removal of the modular component is achieved during the normal operation of the latch mechanism.

14. The method according to claim 13 further comprising sliding the modular component into sliding engagement with the housing.

15. The method according to claim 14 further comprising applying force to the modular component to resiliently engage the modular component with the housing.

16. The method according to claim 15 further comprising using the sensed magnetic field of the latching pin to issue an alert when the striker is engaged with the keeper and the latch pin is not in a latched condition.
