Description

DOOR CONSTRUCTION AND KET THEREFOR
This invention relates to a door construction and to a kit therefor.
Many doors nowadays consist of frames in which are mounted infill panels which basically are a thickness of an insulating fire-retardant foamed plastics material (e.g. STYROFOAM) sandwiched between quite thin skins of a suitable plastics material (e.g. UPVC) . The infill panels often have profiled areas simulating the mouldings used in wooden doors and some of the profiled areas surround apertures within which are mounted double-glazed units which are specially prefabricated.
There are two methods in use for glazing such infill panels, namely, pre-glazing and kit-glazing, each of which is discussed below:-
With pre-glazing, the double-glazed unit is bonded in the panel during manufacture. The advantage obtained is that there is no unsightly glazing trim to be seen because the double-glazed unit is incorporated into the structure of the infill panel during its manufacture and is not added to an infill panel whose manufacture is complete except for the glazing unit. Some of the disadvantages concomitant with use of the pre-glazing method are:
(a) the double-glazed unit has to be put in place during manufacture;
(b) each door, including its infill panel, needs to be specially made;
(c) every door has to be individually ordered by the customer and then has to be individually made by the door maker;
(d) if the double-glazed unit becomes broken, the unit cannot be replaced because the various elements constituting the infill panel have been bonded together and this has the consequence that the entire infill panel has to be scrapped;
(e) the glass has to be bought in by the infill panel maker because of pre-glazing;
(f) all of the glass needs to be specially ordered, possibly to a special, complicated shape; and
(g) the customer for these doors is often a double-glazing company which would usually make its own glass units or buy them in at very competitive prices. However, in pre-glaze, the company has to buy glass in from the infill panel maker at a higher cost. Thus, the eventual cost of the door is increased by too many middle-men adding their own profit margins.
With kit-glazing, the infill panel is made with an aperture and an associated rebate or seat in which the double-glazed unit is placed and is thereafter secured in position by the application of separate trim. The disadvantages of the kit-glazing method are:
(1) the unsightliness of the trim on the inside of the door;
(2) the security given is rather questionable because the double-glazed unit is only held in position by a relatively flimsy piece of trim and some adhesive; and
(3) by virtue of having to use trim to secure the unit in position, said double-glazed unit needs to be very accurately made.
There is therefore a need for a door infill panel capable of accommodating standard glazed units, which can be assembled on site, and which provides adequate security and enhanced aesthetic appeal.
The above disadvantages of the prior art are obviated to a substantial extent by the present invention in which the door infill panel comprises apertured panel portions which cooperate in use to hold a glazing unit between them.
In one aspect the present invention provides a door infill panel which comprises apertured panel portions which, in use, are arranged with their apertures in register so as to form an opening, and which, in use, cooperate to retain a glazing unit in place in the opening so formed.
In another aspect the present invention provides a method of glazing a door infill panel in which apertured panel portions are arranged with their apertures in register so as to form an opening, and a glazing unit is placed in the opening and retained therein by the cooperating apertured panel portions.
In a further aspect the invention provides a door having an infill panel comprising apertured panel portions which are arranged with their apertures in register so as to form an opening, the panel portions cooperating to retain a glazing unit in place in the opening so formed.
In a still further aspect, the invention provides a kit of parts for the construction of a door infill panel as hereinafter described.
Preferably at least one of the panel portions is of laminate construction, for example comprising an insulating layer and a reinforcing layer. The insulating layer can, for example, be a layer of foamed plastics material, suitable examples of which include foamed olefin polymers such as cellular polystyrene and other foamed structural materials such as foamed polyurethanes. The reinforcing layer is preferable a rigid sheet of a material such as metal, for example steel or aluminium, plywood, hardboard, or a rigid extruded plastics material.
Preferably each of the panel portions is of laminate construction, and most preferably they are of similar or identical construction. Preferably the panel portions are arranged so that at least one reinforcing layer is situated between the insulating layers, and most preferably the panel portions are both laminated and arranged such that their reinforcing layers are adjacent each other. In this specification this arrangement will be described as "back-to-back". In a preferred embodiment, the two reinforcing layers are in contact with each other.
One or each of the panel portions may, if desired, be faced with a surface layer, which may be decorative and/or profiled. The surface layer may be shaped or profiled so as to form a rebate around the aperture in the or each panel portion. In a preferred construction, each panel portion is provided with a rebate around its aperture, and the rebates cooperate with each other to retain the glazing unit in the opening. The rebates may in some circumstances be formed by or include layers other than the surface layers.
Preferably the or each surface layer comprises a profiled skin of a plastics material.
The apertures in the panel portions may be of any desired size and shape, and, as described hereinafter need not necessarily be of the same shape as each other, nor of the same shape as the glazing unit provided.
The apertured panel portions cooperate, in use, to retain the glazing unit in the opening formed by the apertures, and as previously described this is preferably achieved by cooperating rebates around the apertures.
Other arrangements are, however, also possible, and for example the edge regions of the glazing unit could be sandwiched between the apertured panel portions and supported by internal struts in the door.
In a preferred embodiment of the invention, a door infill panel comprises two panel portions disposed back-to- back with at least one double-glazed unit accommodated in said portions in rebates which face one another; apertures in the panel portions in register with said rebates; each panel having a layer of an expanded cellular polystyrene sandwiched between a profiled skin of a plastics material and a rigid sheet; the two rigid sheets of said panel portions being in contact with one another.
In certain preferred constructions, the panel portions are mounted in a door frame without there being any connection of the portions to one another, other than through the frame and, in certain circumstances, the glazing unit.
Alternatively, the panel portions may be connected to one another (for example, by mechanical dowelling, spaced spots of adhesive or by small amounts of double-sided adhesive tape) before being mounted in a door frame.
Dependent upon requirements, the thickness of each rigid sheet may be minimal (for example, 0.25 millimetre) or may be far greater in order to reduce the thickness of the expanded cellular polystyrene and/or to increase security and/or fire retardation.
In an infill panel according to the invention, the apertures through which, in the completed door, the viewer can look may be of shapes and/or sized and/or numbers different from that or those of the glazed unit(s) . Thus, by way of an illustrative example of this feature, there is a so-called "Carolina" window which is incorporated in doors nowadays and which has an upwardly arcuate upper edge and a straight lower edge which is interrupted at its mid-way point by a rather small upwardly arcuate portion; the aperture of that shape may be formed in the profiled skin of plastics material and in the polystyrene layer and in the rigid sheet. Thereafter, when forming the rebate in which half of the thickness of the double-glazed unit is to be housed, that rebate could be made rectangular in order to match the shape of a rectangular double-glazed unit, such a unit bein cheaper to make than one whose shape would exactly match tha of the original aperture. moreover, by way of anothe illustrative example of this feature, a block of four smal apertures which are spaced vertically and horizontally fro one another could be glazed by providing a large rebate whic would accommodate a single appropriately large double-glazed unit covering all of the original apertures.
An embodiment of a door infill panel according to the present invention will now be described with reference to and as illustrated in the accompanying Drawing which shows a horizontal section through part of a door provided with an infill panel according to the invention.
Referring to the Drawing, the door comprises a stile l, formed from an extruded hollow plastics profile having a channel region 2 within which there is arranged an infill panel 3. One wall of the channel region is bordered by an interlocking bead 4 which can be removed in order to insert the infill panel 3. Resilient mounting strips 5 and packing means 6 are provided to locate the infill panel firmly within the channel region of the stile. The infill panel itself comprises two identical panel portions 7 and 8 which are of laminate construction. Each panel portion comprises an insulating layer of foamed polystyrene 9, 10, sandwiched between a rigid sheet 11, 12 of steel, plywood, plastics material or aluminium, and a vacuum formed plastics door skin 13, 14. Each door skin is provided with profiled regions 15, 16, 17 and 18, which extend beyond the edges of the foamed polystyrene and rigid sheet layers surrounding the apertures 19, 20 in the panel portions 7, 8. The profiled regions thus form rebates into which a double-glazed unit 21 can be fitted. The double-glazed unit 21 is held in place in the opening formed by the apertures 19, 20 by the edges of the profiled regions 15, 16, 17, 18 to which edges it is adhered by double-sided silicone tape 22.
In the construction shown, the rigid sheets 11, 12 are in contact, but are not directly connected together, thereby permitting differential thermal expansion without warping of the infill panel.
In assembling the infill panel, the interlocking bead 4 is removed, and panel portion 7 placed in position, the double-glazed unit 21 is then positioned in the aperture 19 of the panel portion 7 and secured with the silicone tape 22. Next the panel portion 8 is placed in register with panel portion 7 and secured to the double-glazed unit 21 with silicone tape 22. Finally the interlocking bead 4 is replaced thus completing the assembly.
Some advantages obtained by the employment of preferred embodiments of an infill panel according to the present invention, or of a kit of parts whose use will enable the construction of a preferred infill panel according to the present invention, are as follows :-
1. The infill panel looks like a pre-glazed panel because there is no visible trim, but the disadvantages of the pre-glazing technique are avoided.
2. If the glazing unit becomes broken, it can be replaced easily, even if the panel is mounted in a door frame.
3. Greater security due to the two rigid sheets which are in contact with one another in the middle of the panel.
4. When fitting numbers, door knockers and/or letter boxes, self-tapping screws can be used which will penetrate into said rigid sheets which are in contact with one another.
5. Misalignment of the profiles on the inner and outer skins of the complete infill panel is avoided because the double-glazed units will ensure correct alignment due to the fact that each such unit has one half of its thickness accommodated in each panel portion.
6. As the infill panel is made in two halves, damage to one half (e.g. in transit, or if marketed in kit form) will not result in the whole panel having to be scrapped. another panel portion can be provided to replace the damaged one and this therefore reduces the scrap rate.
7. A fabricator can stock panel portions having different finishes (e.g. white plastics material, red plastics material and wood-grain-finish plastics material) and can make-up doors to suit a customer's requirements without needing to put in a special order.
8. When the two panel portions of an infill panel are fitted unconnected, the "bi-metallic effect" of hot sun on dark-coloured panels (e.g. wood grain effect or brown) is avoided because thermal expansion of one portion relative to the other is allowed to take place.
