Abstract

A threshold seal for a door (1) which is hingedly mounted on a fixed structure comprises a first part (5) having a rigid strip (7) attached to the door and a resiliently flexible strip (8) extending downwardly from the rigid strip and away from the door, the rigid strip having a downwardly facing surface (12) extending away from the door and overhanging the resiliently flexible strip, and a second part (6) having a rigid strip (13) attached to the threshold and a resiliently flexible strip (14) extending upwardly and towards the door, wherein when the door is closed respective surfaces of the flexible strip of the first part and the flexible strip of the second part bear against each other and the upper edge (16) of the flexible strip of the second part is disposed beneath the overhanging surface of the first part. When the door is closed, the two flexible strips resist passage of draughts and water. In addition, the rigid strip of the first part assists in guiding rain or other water which has run down the door (on the side of the seal parts) away from the interface between the two flexible strips to thereby further reduce the possibility of water passing underneath the door. <IMAGE>

Description

SPECIFICATION Threshold seal The present invention relates to a threshold seal for a door, window or the like (hereinafter referred to as a door for convenience) which is hingedly mounted on a fixed structure.

Various threshold seals are known for doors which are hingedly mounted on a fixed structure. Such seals are provided for preventing draughts between the door and the threshold and for preventing ingress of water past the door between the bottom of the door and the threshold.

The invention aims to provide an improved threshold seal for doors which are hingedly mounted on a fixed structure.

In accordance with the present invention, there is provided a threshold seal for a door which is hingedly mounted on a fixed structure, the seal comprising: a first part having a rigid strip attached to the door and a resiliently flexible strip extending downwardly from the rigid strip and away from the door, the rigid strip having a downwardly facing surface extending away from the door and overhanging the resiliently flexible strip; and a second part having a rigid strip attached to the threshold and a resiliently flexible strip extending upwardly and towards the door, wherein when the door is closed respective surfaces of the flexible strip of the first part and the flexible strip of the second part bear against each other and the upper edge of the flexible strip of the second part is disposed beneath the overhanging surface of the first part.

In this arrangement when the door is closed, the two flexible strips resist passage of draughts and water. In addition, the rigid strip of the first part assists in guiding rain or other water which has run down the door (on the side of the seal parts) away from the interface between the two flexible strips to thereby further reduce the possibility of water passing underneath the door.

Preferably when the door is closed it abuts stop means, such as a sill.

The present invention is further described below by way of example with reference to the accompanying drawings, in which Figure 1 is a sectional view through a threshold seal according to the invention, the door being in its closed position; Figure 1A shows a detail of Figure 1 on a larger scale; Figure 2 is a sectional view similar to Figure 1 but showing the door slightly open; Figure 3 is a perspective view of the threshold seal, the door being in its closed position.

Referring to the drawings, a door 1 is conventionally mounted by means of hinges on a door frame (not shown) for movement about a vertical axis. The door can open inwardly in the direction indicated by arrow A. The door frame and the floor 2 define a door opening at the threshold of which is a sill 3 affixed to the floor. Affixed to the floor 2 outside the door opening is a batten 4. When the door is closed, the lower edge of the door 1 abuts the sill 3, as shown in Figure 2, and the margins of the face 1' of the door abut the jambs and head of the door frame in conventional manner, thereby stopping movement of the door outwardly from its closed position.

To the door, on its outer side and adjacent its lower edge is affixed a first seal part 5. To the batten 4 is affixed a second seal part 6.

The first seal part 5 consists of a rigid plastics strip 7 and a resilient flexible strip 8 of the synthetic rubber. The strip 7 is attached to the door by nails 10 (only one of which is shown in Figure 1 and which are omitted from Figures 2 and 3 for the sake of clarity). The resilient flexible strip 8 projects downwardly and away from the door 1 and tapers towards its lower, free edge 11 (see Figure 2).

The rigid strip 7 has a downwardly directed lower surface 12 which overhangs the strip 8.

The second seal part 6 consists of a rigid plastics strip 13 and a resiliently flexible strip 14 of synthetic rubber. The strip 13 is attached to the batten 4 by nails 15 (only one of which is shown in Figure 1 and which are omitted in Figures 2 and 3 for the sake of clarity). To assist the penetration of the nails through the strip 13 and to prevent the strip splitting grooves 16 are provided in the strip. The resilient flexible strip 14 projects upwardly and towards the door and tapers towards its upper free edge 16.

As will be appreciated, the first and second seal parts are of like shape and construction. The parts 5 and 6 may be formed by co-extrusion of plastics (which when solid is rigid) and synthetic rubber and may be respective cut lengths of a common coextrudate.

When the door is closed the upper surface of the flexible strip 8 and the lower surface of the flexible strip 14 contact and bear against each other as shown in Figure 1 and 1Ato provide draught- and water-resistant sealing between the parts 5 and 6.

Furthermore, the upper, free edge 16 of the strip 14 is located beneath the overhanging surface 12 of the rigid strip 7 of the first seal part 5. Thus rain or other water running down the outer surface of the door is deflected by the strip 7 onto the upper surfaces of the resilient strip 14 and the rigid strip 13 and away from the interface between the two resilient strips 8 and 14. Thus no water which has run down the door 1 should penetrate between the resilient strips 8 and 14. Consequently ingress of any of the water from the outside to the inside of the door 1 at the threshold of the door opening is prevented when the door is closed.

1. A threshold seal for a door or window or the like (hereinafter referred to as the door) which is hingedly mounted on a fixed structure, the seal comprising. a first part having a rigid strip attached to the door and a resiliently flexible strip extending downwardly from the rigid strip and away from the door, the rigid strip having a downwardly facing surface extending away from the door and overhanging the resiliently flexible strip; and a second part having a rigid strip attached to the threshold and a resiliently flexible strip extending upwardly
