A traffic door biased to the closed position and adapted to be swung to the open position when pushed manually or engaged by material handling equipment. The traffic door includes an inverted L-shaped frame and a spring loaded cam mechanism is associated with the upper horizontal frame section of the frame and acts to bias the door to the closed position. Both the vertical and horizontal frame sections include a hollow rail having longitudinal recesses in opposite edges. The door panels are secured within the inner recesses of the rails by wedge-shaped strips, while channel members are secured in the outer recesses and carry a pair of weather strips which engage the jamb and header of the doorway. The outer vertical edge of each door panel is clamped within an edge seal strip which includes an outer flexible hinge section and a pair of arms having teeth or serrations which are clamped to opposite faces of the respective panel. Each edge seal strip has cooperating male and female locking elements with ratchet type teeth which maintain the arms of the strip in locking engagement with the panel.
A traffic door to be mounted in a doorway and comprising a frame, means for mounting the door for swinging movement between an open and a closed position, a panel carried by the frame, an edge seal strip connected to a vertical edge of the panel, said strip being generally U-shaped in cross section and including a central generally flexible section and a pair of substantially rigid arms extending outwardly from the central section and disposed in engagement with opposite sides of the panel, said arms having serrations on the surfaces thereof facing the panel, and locking means connected to said arms and located between the flexible section and the panel, said locking means including cooperating male and female locking elements with said elements having cooperating ratchet type teeth.
A traffic door to be mounted in a doorway, comprising a frame, means for mounting the door for swinging movement between an open and closed position, said frame including a rail having a longitudinally extending recess and said rail having opposed inclined surfaces bordering said recess, a panel having an edge portion disposed within said recess, a pair of clamping members disposed within the recess on opposite sides of the panel to clamp the panel to said rail, each of said clamping members having an inclined surface cooperating with one of the inclined surfaces of the rail to thereby wedge the clamping members into tight bearing engagement with the panel as the clamping members are moved inwardly of said recess and a plurality of fasteners for connecting the clamping members to the rail.
