Abstract
Disclosed is a door sealing mechanism for sealing specifically the horizontal gaps between bottom rail and sill and between top rail and lintel. The door sealing mechanism comprises a sealing member including a flexible, elongated blocking portion having a length greater than the height of the horizontal gap. A retractable mounting piece is used to mount the sealing member thereon and which is retractable when the sealing member is subject to an external force. An elastic member as a spring is coupled to the retractable mounting piece, which exerts a force on the sealing member when the retractable mounting piece is in retracted position and also allows the retractable mounting piece to restore to original position after the external force on the sealing member is removed. When dosing the door, the blocking portion is bent and the retractable mounting piece is retracted; and when the door is in closed position, the combination of the bending of the flexible blocking portion and the force exerted by the elastic member together allows the blocking portion to be in forced contact with the sill or the lintel. The door-sealing mechanism will not hinder the movement of the door and which…
