ABSTRACT:
A two-section portable gate carries a rotatable control handle at an upper surface thereof for purposes of installation and removal of the gate in a doorway. When the handle is rotated to an extended state, the two sections of the gate can be moved relative to one another to fill the opening in the doorway. When the handle is moved to an intermediate position, the gate sections are locked together and further relative movement is not possible. When the handle is moved to a closed or locked position adjacent to an upper surface of the gate, the gate sections are forced apart a predetermined distance thereby creating normal forces, and in turn frictional forces, which lock the gate into position in the doorway and resist its removal. Spring loaded bumpers can be used on edges of the gate sections to take into account non-square openings.
