Patent attributes
The invention relates to a safety gate including a frame with a horizontal base member and usually two vertical upright post members affixed to each end of the base member at its lower end; a door mounted for hinged opening movement, hingedly attached to the vertical upright post member; the frame being held in position by frictional engagement against supporting walls of an opening, provided and adjusted by attachment means which are mounted on adjusting rods; the door includes an upper bar and a lower bar connected together with a number of pales spaced apart to form an effective barrier; the door also including a closing mechanism for releasibly retaining the door in the closed position. The attachment means includes a pressure gauge which measures the frictional pressure between the frame and supporting wall of the opening, and an electronic processing means which compares the pressure reading from the pressure gauge to a predetermined level and indication means which provide an indication when the measured pressure level is lower than the predetermined level. Power storage means are provided to provide autonomous power to the processor and the indication means. The indication means includes a wireless transmission means to transmit the indication of low pressure to a computer, tablet or smart phone.
