Abstract: A sealing assembly for sealing a gap between a swing door and a floor comprises a sealing member installed to be able to rotate from a closed position to an open position, an elastically deforming member made of an elastomer composition engaged to the sealing member, and a seal driving member to rotate the sealing member from the closed position to the open position when the door is opened. The elastically deforming member is deformed when the sealing member rotates from the closed position to the open position, and the sealing member returns from the open position to the closed position by elastic force of the elastically deforming member when the door is closed.

Abstract: A solid skirt seal mounted to the bottom edge of a slide-glide door panel hinged to rotate about an axis generally parallel to the bottom edge of the door panel, a spring biasing the hinged skirt seal to rotate the lower edge of the skirt seal in a downward direction, and a flexible cover extending between the lower edge of the skirt seal and the lower edge of the door panel.

Abstract: An automatic door bottom for a hinged door which is pivotable to be positioned over a sill when closed, the door having a hinge side and a width, the door bottom having an inverted channel having an open bottom, a length corresponding to the door width and a hinge end corresponding to the hinge side of the door; a sealing member having a length corresponding to the length of the channel, the sealing member being housed in the channel and being movable vertically downwardly into a sealing position in which the sealing member will contact the sill when the door is closed; and a displacement mechanism installed in the channel and coupled to the sealing member for moving the sealing member vertically into the sealing position in response to closing of the door, wherein the displacement mechanism is coupled to the sealing member at a plurality of points along the length of the sealing member and is operative to move the end of the sealing member at the hinge side of the channel into the sealing position prior to t

Abstract: A loading dock shelter having rotating seal members is provided for forming a relatively air-tight seal between the dock opening and a truck so as to prevent air movement between the inside and the outside of the building during loading and unloading operations. The loading dock shelter has a frame assembly rigidly attached to the periphery of the dock opening and seal members rotatably mounted to the frame assembly on either side of the dock opening so that the truck may fit therebetween and form a seal between the exterior walls of the truck and the seal member. The seal members are rotatably movable between a first (open) position and a second (sealing) position in response to the movement of the truck into and out of the loading dock. In the first position, the seal members project into the path of the truck so that the truck engages the seal members as it backs into the loading dock.

The seal members are rotatably mounted to the frame assembly for rotation between a first (open) position and a second (sealing) position in response to the movement of the truck into and out of the loading dock. In the first position, the seal member is spaced outwardly from the wall and the loading dock so that it does not interfere with the normal operation of the loading dock and so that it projects into the path of the truck for engaging the truck as the truck backs into the loading dock.

Abstract: Automatically actuated seal constituted of a profile molding connected to a movable panel in a frame, a sill, or a portion of the casing of the frame, and having an elongated sealing element, mounted in a groove of the profile molding and able to be displaced between a retracted position and a projecting sealing position under the effect of an actuating device lodged in the profile molding and having a sealing joint with several legs, one of which is connected to the sealing element and another to the profile molding.
