Latches for gates and doors

A latch for holding closed a gate (or door) wherein the latch is adapted to co-operate with a striker arm, 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 a 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,
• the locking element being in the form of a rotor rotatably mounted in the housing, and
• (g) the rotor having a portion remote from the lock capable of being engaged by a remote actuating unit which may be mounted on an opposite side of the gate post to the latch for remotely operating the latch via the rotor.
