Patent number: 9771740Abstract: A latch has a displaceable latching element in a housing for engagement with a separate striker arm to be latched behind an engagement shoulder of the latching element. The housing mounts a cylinder lock to receive a key from the front. A rotor is mounted on the rear of cylinder lock and rotation of the key rotation the rotor to drive a locking element to engage and lock the latching element. The rotor may also be axial displaceable against spring biasing responsive to a rear unit pushing element whereby unlocking from a rear cylinder lock may rotate the rotor to unlock and pushing causes the latching element to be displaced against its biasing to release the striker arm. Embodiments include a gravity biased and manually opened latch and a spring biased self-locking embodiment.Type: GrantFiled: October 24, 2016Date of Patent: September 26, 2017Assignee: D & D Group Pty LtdInventors: Irek Karcz, Anthony John Clark, Margaret Antkowiak

Patent number: 8127578Abstract: A gate latch is adapted to be installed on a gate post and a complementary striker arm is secured typically to a gate so that, upon closure of the gate, the striker arm engages a displacable latching element mounted in a housing of the latch to displace the latching element. The latching element is biased towards its open position but when the striker arm engages with the latching element it is displaced, thereby releasing an interference portion of a biased locking element, whereby the locking element is released to move under its biasing into a locking position so that self-locking is provided for the latch. A rotary release mechanism may be actuated to return the locking element so that the latching element can be released to release the striker bar and the gate may be opened.Type: GrantFiled: January 31, 2007Date of Patent: March 6, 2012Assignee: D & D Group Pty LtdInventors: Irek Karcz, Anthony John Clark, Dezso Kiraly

Patent number: 7390035Abstract: A magnetic self-latching device for a gate has a main body with handles on either side for operation or has an arrangement to be remotely actuated, for example electrically. A latching body has a high strength magnet usually provided at the bottom of a cavity which defines a latching shoulder. The latching body is adapted to be fixed to a gate post. The main body, with its housing, can be mounted on the gate frame and incorporates a latch pin which, in the door-closed position, is displaced by magnetic attraction to an extended latching position and against the biasing of a return spring. The gate cannot be opened until actuation of the mechanism occurs, for example by rotating a handle to retract the pin against the magnetic force; the gate can then be swung open. When the handle is released, the biasing spring retains the latch pin in a retracted position.Type: GrantFiled: January 13, 2005Date of Patent: June 24, 2008Assignee: D&D Group Pty LimitedInventors: Irek Karcz, Anthony John Clark
