Disclosed is a self-latching gate latch device. The device comprises a latch and a magnet assembly housing. The latch assembly housing, secured to a hinged gate, comprises a slidable horizontal latch bar, attractable by a magnet. The magnet assembly housing comprises a slidable vertical magnet bar secured with a magnet at the bottom thereof. In a lock position of the magnet bar, the latch bar engages the magnet. The magnet assembly housing further comprises a locking member that, in an engagement position, engages the magnet bar to the magnet assembly housing preventing the magnet bar from any upward movement. Within the magnet bar is disposed a lock bar, which when depressed, frees the magnet bar. |

1. A self-latching magnetic gate latch device for latching a hinged gate to a barrier member, the self-latching device comprising:
(a) a latch bar assembly comprising:
(i) a latch assembly housing fitted to either the hinged gate or the barrier member; and(ii) a horizontally-disposed latch bar slidably disposed within the latch assembly housing such that, the latch bar is axially movable from a default backward latch bar disengagement position to a forward latch bar engagement position, the latch bar biased towards the latch bar disengagement position, the latch bar attractable by a magnet; (b) a magnet bar assembly comprising:
(i) an elongate magnet assembly housing vertically fitted to one of the hinged gate or the barrier member whereon the latch assembly housing is not fitted, the interior surface of the magnet assembly housing comprising a horizontal first engagement surface, the magnet assembly housing comprising a latch hole axially aligned with the latch bar;(ii) an elongate vertical magnet bar comprising a magnet secured to the bottom thereof, the magnet bar slidably disposed within the magnet assembly housing such that, the magnet bar is manually vertically movable from a default downward magnet bar engagement position to an upward magnet bar disengagement position, the magnet bar biased towards the magnet bar engagement position, where the magnet, via the latch hole, is aligned with the latch bar, the magnet bar movable by manually lifting the top portion thereof, which extends beyond the top of the magnet assembly housing therethrough; and(iii) a disengagement means disposed within the top portion of the magnet bar; and (c) a locking member disposed in conjuction with the magnet bar, the locking member comprising a horizontal top second engagement surface, the locking member, upon the deployment of the disengagement means, is horizontally slidably movable from a forward locking member engagement position where, in the magnet bar engagement position, the second engagement surface engages the first engagement surface through the magnet rod thereby preventing the magnet bar from any upward movement, to a backward locking member disengagement position, where the second engagement surface disengages the first engagement surface thereby allowing the magnet bar to slide upwards, the locking member biased in the forward direction;wherein, as the magnet bar is in the magnet bar engagement position and as the hinged gate and the barrier member are brought closer to each other, the latch bar, which is longitudinally aligned with the magnet in the magnet bar engagement position, as a result of the attraction force of the magnet, arrives to the latch bar engagement position, where the latch bar abuts the magnet through the magnet assembly housing thereby, latching the hinged gate and the barrier member together and wherein, as the magnet bar is lifted to the magnet bar disengagement position, the increase in the distance between the magnet and the latch bar causes the attraction force between the magnet and the latch bar to weaken resulting the latch bar retracting into the latch bar disengagement position thereby unlatching the hinged gate from the fence post. |
