ABSTRACT:
A security device for obstructing movement of children or animals through an entryway includes a barrier mounted on a frame. The frame is made of substantially linear and rigid bars which are pivoted together to form one collapsible parallelogram which extends substantially entirely across the entryway. A movable pressure member is mounted on a vertical bar of the frame for laterally outward movement when the vertical bar moves down relative to the pressure member. To facilitate collapse of the frame to a position where all of the bars are parallel, each of two diametrically opposed pivots has its axis inwardly offset from the longitudinal axis of one of the bars it interconnects, and the barrier member is a net in which rectangular openings are formed by members which are substantially parallel to the bars. A frame-supporting hinge has a generally vertical hinge axis to permit horizontal swinging movement of the device.
