Magnetic Door Latch and Lock Mechanisms
In a door latch for a hinged or pivoting door having a latch fixture mounted in or on the door that supports a slideable bolt that is magnetically attracted to a fixed strike so as to effect latching action by extension of the bolt, a safety catch mechanism which, while 5 engaged, prevents the bolt from extending, the safety catch mechanism having a catch member that operatively acts between the moveable bolt and the latch fixture, and means to operate the catch member responsive to magnetic forces from the strike. First and second actuators are disposed to opposite sides of the door, each of the first and second actuators being coupled to the latching mechanism to effect withdrawal of the latch bolt 10 from its extended position to its retracted position upon operation by a user. A privacy lock mechanism is operable from one side of the door only, and can be used to prevent the actuator on the other side of the door from operating the latch.
