ABSTRACT:
A sealing apparatus for use with a door which swings over a threshold between an open position and a closed position and has a door lower end spaced above said threshold and defining a gap between the door lower end and the threshold when the door is in the closed position, and has a door face and a door frame includes a mechanism mounting member; a gate member for closing the gap; a leaf spring having a leaf spring first end and a leaf spring second end, the leaf spring first end being secured to the gate member with a securing structure, and the leaf spring second end being secured to the mounting member with an anchoring structure, where a segment of the leaf spring angles upwardly and laterally to form a spring cam surface; a structure for guiding the gate member to move up and down relative to the door; a cam engaging member positioned above and substantially parallel with the gate member, the cam engaging member having a protruding end extending laterally from the door toward the door frame to abut the door frame as the door is closed, the cam engaging member having a cam engaging element positioned adjacent to the spring cam surface; a structure for guiding the cam engaging member to move laterally relative to the door; so that closing the door causes the door frame to depress the cam engaging member protruding end, thereby sliding the cam engaging member horizontally and causing the cam engaging element to abut and deflect the spring cam surface to pivot the leaf spring downwardly and to thereby lower the attached gate member to make sealing contact with the threshold.
