Latches for gates and doors

A latch assembly for holding closed a gate or door wherein the latch assembly is adapted to co-operate with a striker arm, the latch assembly comprising:

• a latch mountable to the gate or a gate post;
• and
• a rear actuating unit mountable on an opposite side of the gate or gate post to the latch;
• the latch comprising;
• (a) a housing in which
• (b) a displaceable latching element is mounted to be displaceable from a latching position towards an open position in which the striker arm is released for gate opening, and
• (c) the latching element having a latching shoulder to retain the striker arm when engaged behind the latching shoulder and having an engagement surface adapted to be engaged by the striker arm when the gate is moved towards a closed position to displace the latching element and for permitting relative movement of the striker arm to adopt a position behind the latching shoulder,
• (d) a key-operated lock mounted in the housing and having a key operation for unlocking the latch,
• (e) a locking element for locking the latching element and adapted to be displaced upon actuation of the key-operated lock between a locking position, in which movement of the latching element is restrained from moving, and a displaced position in which the latching element is free to be moved,
• (f) the locking element being in the form of a rotor rotatably mounted in the housing, and the rotor is axially displaceable when in the displaced position;
• and
• (g) the rotor being connectable to the rear actuating unit for remotely operating the latch via the rotor, and wherein the rear actuating unit comprises a second key-operated lock that connects and transmit rotation to the rotor, whereby the housing key-operated lock or the second key-operated lock can be used to displace the locking element between the locking position and the displaced position, whereby the rotor, the housing key-operated lock and the second key-operated lock rotates around a single axis.
