Car operated safety gate for horizontally transferrable elevator cab

A safety gate for preventing a horizontally movable elevator cab at a landing from inadvertently entering an elevator hoistway when an elevator car frame is not present at said landing to receive said cab, comprising:

• a gate member vertically slidable between an upper position, in which a portion of it extends above the floor of said landing adjacent to said hoistway, thereby to obstruct passage of said cab along said floor toward said hoistway, and a lower position, in which said gate member does not obstruct passage of said cab along said floor toward said hoistway;
• a moveable actuator engaging said gate member and moveable between a first position, in which it retains said gate member in said upper position, and a second position, in which it retains said gate member in said lower position, said actuator moving said gate between said upper and lower positions as said actuator moves between said first and second positions;
• means for normally urging said gate member into said upper position and said actuator into said first position;
• and
• means disposed on said elevator car frame for moving said actuator into said second position as said elevator car frame approaches said landing.
