ABSTRACT:
A sealing device automatically seals a gap between a door bottom and a floor in response to closing movement of the door. The sealing device includes a support element attachable to the door bottom, a seal actuating element movably supported from the support element by spring elements, and a sealing element carried by the seal actuating element. The sealing device may be mounted to the inside or outside of a door, or mortise-mounted in the door, and may be mounted to left- or right-opening hinged doors, or to sliding or articulated closures, and may be provided as an after market or OEM device. The spring elements in the preferred embodiment are one-piece and are integrally connected to both the support element and the seal actuating element, thereby forming a one-piece sealing device preferably made of plastic. In embodiments where lateral movement of the seal actuating element is required to seal the gap, a projection on the seal actuating element is engaged by a door jamb surface or an element attached thereto during door opening and closing. A cover for the device is attached without fasteners e.g., by snap-fitting or slide fitting, and may act as a kick plate, and may be decorative. The length of the sealing device may be easily reduced or expanded to fit various size doors. The invention also provides a device which holds the seal actuating element a predetermined distance from the support element during installation of the device on the door to facilitate installation.
