Abstract

An extrusion for a door or window frame comprises an elongate body 10 having a cross-sectional profile which defines a longitudinally-extending rebate 11 having a first and second outwardly facing diverging side walls 12,13, and a longitudinally-extending flexible seal 20. The seal 20 comprises a first longitudinally extending portion 21 which extends out into the rebate 11 from an inner portion 14 of the first side wall 12 and a second longitudinally-extending portion 22 which extends from the outer end of the first portion 21 over the first side wall 12 and back to an outer portion of the first side wall 15, the first portion 21 of the seal is thicker, less flexible and more resilient than the second portion 22. The seal can be co-extruded with the frame member. In use, the seal can either form a static seal against a glazing unit, wherein the glazing unit is firmly engaged by the more resilient first portion 21 of the seal, or a dynamic seal against an openable door or window, wherein the door or window seals against the more flexible second portion 22 of the seal.

Description

This invention relates to an extrusion for a window, door or other opening.
Glazing systems are well known which have windows and doors comprising frames formed of an extruded plastics material, such as unplasticised polyvinyl chloride (UPV). Typically, the frame members are designed to perform specific roles. A first role comprises acting as a frame for a fixed window, in which a glazing unit is seated in a rebate formed around the frame, the unit being secured in place by beading members which snap-engage the frame. It is important that the frame and the beading members comprise resiliently-flexible seals which seal against respective opposite faces of the glazing unit round the periphery thereof. Such so-called static seals need to be relatively hard and resilient to hold the glazing unit in-situ. In order to enable the glazing unit to be fitted, the width of the seals need to be minimised as far as possible, so that they can be compressed into place.
A second role of the frame members is to act as a supporting frame around the opening door or window, in which the door or window is hinged to one side of the supporting frame and fits into a rebate around the frame when closed. A third role of frame members is to act as a peripheral sash around the opening door or window itself. Typically, such sashes also comprise a rebate arranged to receive the supporting frame when the window or door is closed.
It is important that the peripheral frame members and/or the sash members comprise a resiliently flexible seals, which seal against the opposing extruding member, in order to prevent draughts and to prevent ingress of water. Such so-called dynamic seals needed to be relatively soft to allow the door or window to close tightly against the seal around its full periphery. The seals also need to be relatively wide, in order to accommodate tolerances in the fitting of the door or window to the supporting frame.
ln order to save tooling costs and to reduce the number of components of the glazing system using such frames, its desirable to form a frame extrusion having a cross-sectional profile which enables the extrusion to be put to a variety of uses.
However, the requirement to have different types of seals for static and dynamic uses makes it difficult to form a single extrusion that can be used for both applications.
We have now devised a window or door extrusion which elevates the above-mentioned problems.
in accordance with the present invention, there is provided an extrusion for a door or window, the extrusion comprising an elongate body having a cross-sectional profile which defines a longitudinally-extending rebate having a first and second outwardly facing diverging side walls, and a longitudinally-extending seal disposed on the first side wall and formed of a material having a greater degree of resilient flexibility than said body, said seal having a longitudinally-extending side wall provided with a first longitudinally-extending portion which extends out into the rebate from an inner portion of said first side wall and a second longitudinally-extending portion which extends from the outer end of the first portion over the first side wall and back to an outer portion of the first side wail, said first portion of the wall of the seal being less flexible and more resilient than said second portion.
in use, a glazing unit can be mounted directly to the extrusion in the aforementioned way, with the beading being snap-engaged with the second side wail thereof. The first portion of the wall of the seal is relatively hard and firmly engages the glazing unit, in order to hold the latter securely in-situ.
Alternatively, the glazing can be used to form a door or window frame or sash. The door or window being mounted to the frame, such that only the second portion of the wall of the seal engages the opposing extrusion when the door or window is closed.
This second portion of the seal is more flexible than the first portion and extends over the first side wall of the rebate and is separated there from. The width of the extension of the second portion of the seal over the first side wall of the rebate is sufficient to allow for tolerances in the fitting of the door or window to the supporting frame.
It will be appreciated that an extrusion in accordance with the present invention can thus be used in a wider variety of roles without having to provide different kinds of seals or seals which seal inadequately.
In one embodiment, the first and second portions of the wall of-the seal extend from a base which is captively engaged with said body portion of the extrusion.
In an alternative preferred embodiment, the seal is formed as a co-extrusion with a said body portion, said first and second portions of the wall of the seat being directly joined to the inner and outer portions respectively of said first side wall of the rebate.
Preferably, the seal is extruded on to the body portion after the lafter has been extruded in a process known as post co-extrusion.
Preferably, the second portion a the wall of the seal extends outwardly onto the rebate from the outer end of said first portion of the wall of the seal.
Preferably, the resilience and flexibility of the seal is varied by varying the wall thickness thereof, said first portion of the wall of the seal being thicker than said second portion.
Preferably, the first portion of the wall of the seal is inclined towards the second wail of the rebate.
An embodiment of the present invention will now be described by way of example only and with reference to the accompanying drawings in which: Figure 1 is a sectional view of an extrusion in accordance with the present invention for a door or window; and Figure 2 is a sectional view of the extrusion of Figure 1 when in use.
Referring to Figure 1 of the drawings, there is shown an extrusion for a door or window, the extrusion comprising an elongate body portion 10 formed of UPVC or another rigid material. The extrusion defines a longitudinally-extending rebate 11 having first and second perpendicular side waIls 12, 13 which diverge outwardly.
The outer end of the first waIl 12 of the rebate 11 is formed with inner and outer longitudinally-extending lips 14, 15, which extend parallel to each other and extend into the rebate 11.
A longitudinally-extending seal 20 is co-extruded onto the outer end of the 1irst wall 12 of the rebate 11. The seal 20 comprises a longitudinally-extending side wall having a first portion 21 which extends outwardly into the rebate 11 from the inner lip 14 The first portion 21 of the seal 20 is inclined towards the second wall 13 of the rebate 11.
The longitudinally-extending side wall of the seal 20 further comprises a second portion 22, which is at least 5D% thinner than the first portion 21 and curves outwardly from the outer end of the first portion 21 over the first wall 12 of the rebate 11 and then curves inwardly to a point where it meets the outer lip 15.
Referring to Figure 2 of the drawings, the extrusion 10 may form a side member of a supporting frame 30 for an opening door or window 31. The door or window 31 is pivoted to the frame, such that it opens to the left in Figure 2 from its closed position as shown.
The door or window 31 is mounted such that, when closed, the inner face 32 of sash 33 abuts a second portion 22 of the seal 20 and not the first portion 21. Likewise an identical seal 34 on the sash 33 abuts the outer wall 35 of the frame 30 in a similar manner. The second portion 22 of both seals 20 are relatively soft and resiliently flexible and thus form a good seal against their respective opposing members. The seals 20, 34 are also wide and thus accommodate for tolerances in the width W between the door 31 and frame 30.
The extrusion 10 also comprises a second rebate 41 on its opposite side, which faces away from the rebate 11 shown in Figure 1. A glazing unit 42 extends into the rebate 41 and is secured in-situ by a glazing bead 43 having a conventional C-shaped seal 44. The bead 43 is snap-engaged with a channel formed on a second wall 46 of the rebate 41. The perpendicular first wall 45 of the rebate 41 is provided with an identical seal 47 to the seal 20 of Figure 1. However, in this arrangement, the entire seal 47 is compressed by the glazing unit 42, such that the outer end of the first wall portion thereof abuts the surface of the glazing unit 42. The glazing unit 42 is thus held in-situ by the thicker and less resilient part of the seal 47.
It will be appreciated that glazing units can be fitted to both rebates 11, 41 of the extruston 10, thereby enabling the extrusion 10 to be used for a variety of dynamic and/or static roles. Similarly, the extrusion of sash 33 could be used in a variety of roles.
An extrusion in accordance with the present invention may have only one rebate and seal, or it may have more than one, for example, on opposite or on all sides thereof.
