A simple and efficient sealing means for a door lacking a threshold and which does not require any major recessing in the door leaf comprises a lath (11) of resilient material, which with a substantually plane main portion (15) is attached to the lower edge of door leaf (10). A head (16), enlarged with respect to the main portion, is provided with sealing ridges (19) and may be bent in relation to the attachment of the lath, so the ridges will be forced towards the floor.
<??>An actuating member (29) comprising a longitudinally compressible leaf spring is fitted between the lower edge of the door leaf and the head (18) of the lath, so it extends outside the vertical hinge edge of the door leaf. Just before the door reaches its closed position the leaf spring contacts the door frame, and will then force the portion of the head adjacent to the hinge edge downwards. During the terminal portion of the closing movement the friction between the floor and the downwardly turned portions of the ridges will <<roll>> the head to full contact with the floor. |
