A safety gate assembly includes a generally U-shaped frame (3), which may be secured across a door opening, stairway or the like, and a gate (8), one side of which is connected by one or more pivotal connections (4, 7) to one side of the frame (3) to permit pivotal movement of the gate with respect to the frame about a pivotal axis and the other side of which carries a projecting latch member (9), which cooperates with a latch (1) connected to the other side of the frame. The latch (1) defines an entry (32) for the latch member and a locking position (36), in which pivotal movement of the gate (8) is prevented. The pivotal connections (4, 7) are constructed to permit linear movement of the gate relative to the frame (3) in the direction parallel to the pivotal axis. The entry (32) is connected to the locking position (36) by first and second paths (32, 44), the first path (42) including a one-way catch (40), which is constructed to permit the latch member (9) to move from the entry (32) to the locking position (36) along the first path (42) but to prevent the latch member (9) from moving along the first path (42) from the locking position (36) to the entry (32). The assembly also preferably includes means arranged to exert a pivotal force on the gate (8) to move it into the closed position in which the latch member (9) is in the locking position (36) within the latch (1). |
