ABSTRACT:
An automatically-actuated sealing device is disclosed which seals a gap between a door bottom (or edge) and a surface defining part of an opening through which weather, dust, insects, etc. may otherwise pass. The sealing device includes a support element attachable to the door bottom, a seal actuating element movably supported by the support element, a sealing element moved by the seal actuating element into a sealing position, and a plurality of metal, plastic or metal and plastic spring elements which couple the seal actuating element to the support element and urge the seal actuating element to seal the gap. The sealing devices operate by coupling the device to the opening defining surface so that opening and closing of the door generates movement of the seal actuating element. A projection on the seal actuating element is engaged by the door jamb or a bearing element attached to the jamb, and is laterally moved in response to opening and closing the door. In another embodiment, spring elements direct movement of the seal actuating member without lateral movement using a cord attached to the seal actuating element and the opening defining surface. The sealing device may be mounted to either side of or in an edge (mortise-mounted) of the door, and to both right and left-opening doors. A one-piece cover with end caps covers the sealing device. The support element is attached to the door using a few screws; everything else, including the cover and end caps, is attached without fasteners.
