Abstract

A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.
