  • Patent number: 9790708
    Abstract: 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. 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.

  • Patent number: 4565078
    Abstract: A locking assembly for a gate locking system comprises a gate movable within opposed channeled guide tracks with one track and gate having aligned apertures. The lock assembly is mounted on the track over the aligned apertures and has a locking bolt slidably mounted within its housing for axial movement between a locking position extending through the track and gate apertures, and an unlocked position removed from the gate and track apertures. The bolt has a radially projecting shoulder on its outer surface between its inner and outer ends. A spring biases the bolt towards its unlocked position. A lug is movably mounted in the housing between a first position engaging the bolt and retaining the bolt in its locking position, and a second position disengaged from the bolt for releasing the bolt for axial movement within the housing.

  • Patent number: 3955838
    Abstract: A door latch mechanism which is actuated by pushing or pulling on a handle in order to disengage the latch bolt mechanism from a strike, thereby avoiding the necessity of having to rotate a knob or handle. The door latch mechanism according to the subject invention is of simple construction and is therefore economical to produce. The mechanism includes a primary latch bolt mechanism slidably mounted within a housing having an open end. The mechanism includes a head portion situated at the open end of the housing and having a bevelled surface, and an integral tail portion. An auxiliary bolt is slidably mounted within the housing adjacent the head portion, the forward portion of the auxiliary bolt likewise projecting through the open end of the housing. The forward portion of the auxiliary bolt is adapted to be urged rearwardly upon rearward movement of the head portion of the primary latch bolt mechanism.
