Definitions
- the invention relates to a flush-fitting door, comprising a surround containing at Least one closing panel.

- the panel - in the form of an opaque panel - can be fitted over the entire area; but one can also - which is preferably the case - weld into the surround an centre cross-member, just Like the hollow PVC section having the same thickness as the section of the surround, said sill dividing the area enclosed by the surround into two, and insulating glass being provided in one of the two part areas. One can fit in the other part area an opaque panel of the same thickness as the insulating glass.
- the invention proposes a tubular section with at least one partition which is provided on one side with the fixed strip and the snap-in flanges for fastening of the panel or insuLating glass, and on the other side has two double-walled strips which are flush with the outsides of the tubular section, and between which an open chamber is formed.
- the centre cross-member is preferably also a tubular section with at Least one partition which is provided, on both sides in symmetrical fashion, with a fixed strip and snap-in fLanges - for fastening of the panel or the insuLating glass - having the same shape as those of the section provided for the surround.
- Dutch Patent Application 8611002 discloses a window or door construction in which the visible sides of the fixed and opening part Lie in the same plane.

Abstract
Description
- The invention relates to a flush-fitting door, comprising a surround containing at Least one closing panel.
- FLush-fitting doors, as we know, are doors which over their entire thickness are recessed in the door frame, as opposed to rebated doors, which rest partially on the door frame with a rebate, which may be produced by fitting a panel of greater dimensions on the door. FLush-fitting doors have to some extent the disadvantage that the measurements have to be more accurate; otherwise the doors will jam in the wall as soon as there is a slight deformation of the door frame. Since rebated doors come partially over the door frame, a reasonable seal is more LikeLy to take place, even if there are considerable dimension differences between the door and the inside of the frame rebate.
- FLush-fitting doors are used widely in the NetherLands, both as inside doors and as outside doors; the Latter particularly for back doors of houses, kitchen doors, balcony doors etc. Hitherto they have been avaiLable only in wood, and not in plastic. Rebated doors of plastic, in particular rigid PVC, are known. Since a rebated door can be quite thick without any problem - there are plastic doors with thicknesses of 63 mm and more - it was relatively easy to design these doors for the currently increasingly required thickness of insuLating glass, so-caLLed double glazing. When insulating glass is being fitted there is generally the problem of the extra thickness in the form of special sections and clamping strips by means of which the glass has to be retained. There are aLL sorts of solutions to this problem when, as in the case of rebated doors, the thickness of the door imposes no essential Limitation. Another, of course very important requirement is that of the strength and rigidity of a door with panel. Here again, a solution is found relatively easily in the case of rebated doors, again because the thickness of the door imposes no Limitations. The end result is that rebated doors of plastic are reLativeLy heavy and crude.
- A rebated door of plastic is described, for exampLe, in British Patent Specification 877,339, in which a (new) door frame of plastic is aLso used. This solves the thickness problem.
- In the case of flush-fitting doors which have to be placed as replacements in an existing wooden door frame the maximum permitted thickness of 41 mm in the two above respects is a considerable restriction. The invention has, however, succeeded in developing a flush-fitting door of plastic which is suitable for taking a panel in the form of insulating glass of sufficient strength and stabiLity, which is easily manufactured by plastic manufacturing techniques, and which is aestheticaLLy very pleasing on account of its slimness, on the one hand, and on account of the chosen design solutions, on the other.
- In the basic concept, the flush-fitting door according to the invention is characterized in that the surround is made up of welded-together hollow PVC sections, and in that the panel is held between strips disposed on the PVC sections and strips which slot behind flanges provided on the PVC sections, the strips being designed in such a way that they Lie fully within the section thickness.
- Within this concept, there is therefore a choice between a number of variants. The panel - in the form of an opaque panel - can be fitted over the entire area; but one can also - which is preferably the case - weld into the surround an centre cross-member, just Like the hollow PVC section having the same thickness as the section of the surround, said sill dividing the area enclosed by the surround into two, and insulating glass being provided in one of the two part areas. One can fit in the other part area an opaque panel of the same thickness as the insulating glass. As regards the design features of the section for the surround, the invention proposes a tubular section with at least one partition which is provided on one side with the fixed strip and the snap-in flanges for fastening of the panel or insuLating glass, and on the other side has two double-walled strips which are flush with the outsides of the tubular section, and between which an open chamber is formed.
- It is further preferable that this should be achieved in such a way that the inside walls of the double-walled strips are provided with raised parts, and that along the top cross-member and the jambs of the surround an auxiliary Lath which snaps into the said raised parts and closes the open chamber is provided.
- As mentioned above, it is easier to obtain a good sealing of the door opening with rebated doors than with flush-fitting doors. The invention now, however, proposes that in the case of the flush-fitting door provision should be made, on the double-walled strip at the contact side of the door, for a groove with raised parts opposite each other in the opening for the purpose of fitting a sealing strip. This sealing strip then simply comes to rest against the rebate in the door frame when the door is closed and - given the great rigidity and stability of the door as a whole, so that warping cannot occur - ensures an exceLLent seal, even if the internal measurements of the door frame differ reLativeLy greatly from the external measurements of the door.
- The centre cross-member is preferably also a tubular section with at Least one partition which is provided, on both sides in symmetrical fashion, with a fixed strip and snap-in fLanges - for fastening of the panel or the insuLating glass - having the same shape as those of the section provided for the surround.
- It is pointed out that Dutch Patent Application 8611002 discloses a window or door construction in which the visible sides of the fixed and opening part Lie in the same plane. This is, however, a design in which a door frame matching the opening part is provided. In the event of replacement, this therefore means that both the door and the door frame have to be replaced. The problem outlined above concerning the thickness for the use of double glazing is hereby solved, but the shape of the opening part is not suitable for use merely as a replacement of a door in an existing wooden door frame.
- FinaLLy, it is pointed out that the periodical "Plastica" 16 (1963) 12, p. 629, describes a PVC door which is designed as a rebated door, but where a matching plastic doorcasing is fastened to a wooden adjusting casing. In design, the door is made up of a Large number of hollow PVC sections which with swallow-tailed connections slide into each other and which are finally connected together by solvent-welding.
- The invention will now be explained with reference to the attached drawing of a preferred embodiment.
-
- Fig. 1 shows a view of the finished door, closed, in a door frame;
- Fig. 2 shows schematically the individual parts from which the door is made up, except for the glass Laths;
- Fig. 3 shows on a Large scale the detail of the connection between centre cross-member and stile after the glass Laths have been fitted;
- Figs. 4A, 4B and 4C give vertical sections according to the arrows IV-IV A, B and C in Fig. 1;
- Fig. 5 shows on an even Larger scale the shape of the section for the surround.
- The flush-fitting door in Fig. 1 is seen from the inside of the room which is being closed off by it, so that the inside of the
door frame 1 is visible. The door comprises a surround which is formed by atop cross-member 2, abottom cross-member 3, and twostiles centre cross-member 6 is also provided. ALL these parts are made of plastic, preferably rigid PVC, and they are welded together. In the top part area produced bycentre cross-member 6, insulating glass (double glazing) 7 is fitted, and the bottom part area is filled with an opaque, also heat-insulating,panel 8. - Fig. 2 shows the individual parts before weLding. In the corners the parts of the surround are mitre-sawed at an angle of 45 degrees, as indicated by 9, 9', in order to form weld faces. The
centre cross-member 6 is provided with beveLLed weld faces, such as 10 and 10'. The jamb is provided with acorresponding notch 11 into which theend 10, 10' is welded. - Fig. 3 shows the end position. It also shows that the strips, which are to be described further below, are mitre-sawed.
- The cross sections of Fig. 4A to 4C give an overall view of the shape of the sections with the different fixing strips for the
panels rectangular tube 13 with apartition 14. On the right side it is provided with afixed strip 15, against which the insulating glass or the insulating panel can be pressed, and has twoflanges 16, 17 which are designed to have a separate strip 18 (see Fig. 4A) snap into them. - The
fixed strip 15 is double-walled along part of its length, as indicated at 18, while there is also agroove 19 for accommodation of a rubber seal. - On the other side, Left in Fig. 5, the
tube 13 is provided with two double-walled strips open chamber 22 is produced between them. The inside walls 20' and 21' of the strips are provided with raisedparts fixed strip 21 is also provided with agroove 25 which has raisedparts rebate 30 in the door frame. - Figs. 4A to 4C will now be clear as regards the fixing of the
panels top cross-member 2 andbottom cross-member 3 and thejambs centre cross-member 6 is shaped differently from the main section (see Fig. 4B). The section of the centre cross-member is provided on either side, in symmetrical fashion, with fixedstrips separate strips strip 15 and the snap-inflanges 16, 17, as described for the main section and shown in Fig. 5. - As can be seen from Figs. 4A to 4C, all strips and flanges Lie fuLLy within the thickness of the tubular form of the sections.
- Fig. 4A shows two further features. The
open chamber 21 described with reference to Fig. 5 on one side of the main section remains open to thebottom cross-member 3. At the top cross-member 2 - and in the same way for thejambs 4 and 5 - this open chamber is closed off by anauxiliary Lath 35 which consists of a flat strip with two raised parts which are provided with snap-in flanges, by means of which this Lath can be fixed behind the raisedparts 23, 24 (see Fig. 5) in the open chamber. This produces a streamlined appearance to the outer periphery of the door, while the solution chosen for it also further increases the rigidity of the sections. - It can also be seen in Figs. 4B and 4C that provision is made in the
bottom cross-member 3 and the centre cross-member 6 - and the same can apply to thejambs 4 and 5 - for a reinforcement in the form of ametal tube 36. This tube has on its top side agroove 37 by means of which it can be fitted more easily in the section, while the shape also produces greater rigidity of the tubular sections.
