Abstract:
1. A safety gate assembly including a frame, which may be secured across a door opening or stairway, said frame having two sides and comprising a base and at least one upstanding limb, and a gate having two sides, one of said sides of said gate is connected by at least one pivotal connection to said one limb of said frame to permit pivotal movement of said gate with respect to said frame about a pivotal axis and the other of said sides of said gate carries a latch member, which cooperates with a latch connected at the other of said sides of said frame, said latch defining a locked position, in which pivotal movement of said gate is prevented, said pivotal connection being constructed to permit linear movement of said gate relative to said frame in a direction parallel to said pivotal axis, said latch member cooperating with biasing means arranged to urge said latch member in the direction away from said one side of said gate, said latch defining a recess, which is adapted to accommodate a portion of said latch member and laterally adjacent which is an entry ramp and extending vertically into which is an exit ramp, said entry ramp being constructed and arranged so that, when said gate is pivoted into said locked position, said latch member engages said entry ramp and is moved by it progressively against the force of said biasing means in the direction towards said one side of said gate until said latch member is in registry with said recess and said biasing means then urges said latch member into said recess and further pivotal movement of said gate is prevented and said gate is in the locked position, said exit ramp being constructed and arranged so that, when said gate is moved linearly upwardly, said latch member engages said exit ramp and is moved by it progressively in the direction towards the said one side of said gate until it is out of said recess, whereafter said gate may be moved pivotally into an open position.
