Abstract

A draught excluder comprises an elastomeric extrusion including an elongate tube having at least one flat surface 2 and a wing 3 extending in a plane substantially perpendicularly to or substantially co-planar to that of the tube, means (e.g. adhesive 5) for attaching the tube to either the door or the adjacent surface via the wing, a first magnetic strip 4 inserted within the tube and a second magnetic strip 6 including means (e.g. adhesives) for attachment thereof to either the said surface or the door so as to be directly opposed to the first magnetic strip when the door is in closed position, at least one of the magnetic strips containing a permanently magnetized material, whereby, when the door is closed, magnetic attraction between the strips caused the elastomeric tubular extrusion to deform and seal the said gap and, when the door is opened, the seal is broken. <IMAGE>

Description

SPECIFICATION Improvements in and relating to draught excluders This invention relates to draught excluders. A draught excluder in accordance with the present invention is particularly suitable for use between a door and a door sill but may also be used to seal other perimetric gaps which are not infrequently present between doors and windows and their adjacent surrounding frame work.

Various forms of draught excluder have been proposed including single component excluders which are fixed to, for example, either a door or a surrounding frame and, upon closure of the door serve to seal a gap between the door and the surrounding frame. A draught excluder has also been proposed comprising two magnetically attractable components which are attached to a door and door frame respectively so that, upon closure of the door, the two components are magnetically attracted to each other to seal a gap between the door and the surrounding frame.

According to the present invention there is provided a draught excluder for sealing a gap between a door and an adjacent surface comprising an elastomeric extrusion including an elongate tube having at least one flat surface and a wing extending in a plane substantially perpendicularly to or substantially co-planar to that of the tube, means for attaching the tube to either the door or the adjacent surface via the wing, a first magnetic strip inserted within the tube and a second magnetic strip including means for attachment thereof of either the said surface or the door so as to be directly opposed to the first magnetic strip when the door is in a closed position, at least one of the magnetic strips containing a permanently magnetized material, whereby, when the door is closed, magnetic attraction between the strips causes the elastomeric tubular extrusion to deform and seal the said gap and, when the door is opened, the seal is broken.

Preferably a surface of the wing of the elastomeric tubular extrusion and a surface of the second magnetic strip are each coated with an adhesive layer whereby they are attached respectively to the door and to the surface. Conveniently, a draught excluder in accordance with the present invention comprises an elastomeric extrusion in the form of a flattened oblong sectioned tube having a wing extending in a plane substantially perpendicularly to that of the tube, with a first magnetic strip inserted within the tube and with an adhesive layer applied to at least one face of the wing or rib and a removable strip protecting the adhesive layer, in combination with a second magnetic strip having an adhesive layer applied to one surface and a removable strip protecting the adhesive layer, at least one of the strips being of permanently magnetisable material.

The magnetic strip is, preferably, made from a plastic material loaded with magnetic or magnetisable particles such as that supplied by Magnetic Applications Limited of Berkhamsted Hertfordshire England. The magnetic strip may or may not carry a coating of an adhesive material and in the former case, the adhesive coating is protected until use by a removable paper or other tear-off protective layer.

The elastomeric material from which elastomeric extrusion is formed may be made from any elastomeric material for example, a polymer such as p.v.c., or natural rubber.

A draught excluder according to the invention will now be described by way of example, with reference to the accompanying drawings in which figures 1 and 2 show components of the excluder in perspective, whereas figures 3 and 4 show two alternative methods of using the excluder.

The component shown in figure 1 is a generally "L" shaped elastomeric extrusion memberA including an elongate tubular cavity 1 formed with a flat surface 2 and an integral wing 3 disposed at right angles to the tubular cavity. A flexible magnet a magnetisable strip 4 is a snug-sliding fit within the tubular cavity 1. An adhesive coating 5 is applied to the wing 3 and, to assist handling, the adhesive coating is protected by a tear-off protective layer not shown. Alternatively and if desired, the adhesive coating 5 may be applied to face C of the wing 3.

The component shown in figure 2 is a rectangular sectioned strip B of flexible magnetic or magnetisable material 6 having an adhesive coating protective layer system similar to 5 as shown in figure 1.

Figures 3 and 4 show two alternative methods of using the excluder dependant upon which face of the using 3 is coated with adhesive. Although figures 3 and 4 illustrate the excluder applied to the foot of a door in the region of the sill, the excluder may also be used to seal gaps occurring around the other perimetric regions of a door and window.

Further, the excluder may also be used to seal gaps existing around casement windows.

When a doorway is fitted with a storm or weather sill constituting an upstanding sill immediately below a door and over which a person passing through the doorway must step, component A may be modified as shown in figure 5. This modification is especially suitable for external doors.

It will be appreciated from the foregoing that, in use, when a door is closed the magnetically attractable strips A and B are in magnetically attracted to each other to form a seal whereas, upon opening a door the seal is readily broken. In this respect the inherent resilient nature of the elastomeric material for which component A is made serves to afford appropriate latitude in the vent that the components are not correctly aligned or with event that the door and surround may be warped.
