DOOR

Background of the Invention This invention relates to doors, and more particularly to doors which are made of aluminium or other suitable metal.

Although it is known to manufacture doors from aluminium, each different type of door, for example such as those shown in Figure 1, types to have to have their various components separately designed and manufactured, and then assembled.

Brief Summary of the Invention It is therefore an object of the present invention to provide a relatively small number 1o of components which can be used for assembling a number of different types of door.

Accordingly, in one aspect, the invention provides a door comprising a pair of vertical stiles, top and bottom rails extending between the stiles, the stiles and the rails being formed of a first extrusion having at least two spaced apart faces forming part of the sides of the door and at least one hollow therebetween, and at least one connecting extrusion for connection to an inner portion of the stiles and rails at exterior surfaces of the spaced apart faces thereof for mounting one or more panels therebetween.

Preferably, the open face of the first extrusion is provided at an outer edge of the door and there is further provided a blanking extrusion for blanking off the open face of the first extrusion. The blanking extrusion thus preferably provides a closed face forming an edge of the door on which a hinge can be mounted on one side or a lock can be mounted on the other.

In a preferred embodiment, the first extrusion has an open inner face to which is mounted the or each connecting extrusion. Preferably, the panels are panes of glass or other material mounted in suitable resilient sealing means. The first extrusion preferably 25 comprises either one or two parallel members extending substantially perpendicularly between the two closed faces and can be cut to an appropriate length to form each of the tiles and rails.

The or each connecting extrusion can then be cut to the appropriate lengths to be connected to the inner open face of the first extrusion and the blanking extrusion can be l, 30 cut to the appropriate lengths to be connected to the outer open face of the first extrusion.

In one embodiment, a first connecting extrusion extends across the inner portion of Sthe first extrusion and is provided with a portion to which is mounted a second conlecting extrusion having the panel v.Ith the resilient sealing means seated therein. In a second embodiment, the first connecting extrusion is formed in two parts, arranged on either side of the inner portion of the first extrusion, such that the two parts of the first connecting extrusion can be mounted from either side of the door.

The stiles and rails can be fastened together by means of an elongate tie-rod ~Al 1 q extending substantially across the width of the door through the first extrusions forming [N:\LIBLL]00060:LMM 3 the stiles and one of the rails. However, the first extrusion is preferably provided with one or more longitudinal screw receiving recesses to enable the stiles and rails to be screwed together. The blanking extrusions at each side of a corner of the door are preferably fastened together, for example by means of screws.

Preferably, a central extrusion is also provided for extending between the stiles or rails to mount smaller panels according to the desired design of the door.

In a second aspect, the invention provides a system for assembling a door, the system comprising a first extrusion having at least two spaced apart faces defining a hollow therebetween opening to at least one edge of the first extrusion, the first extrusion being adapted for forming at least part of the sides of the door, at least one connecting extrusion for connection to exterior surfaces of said spaced apart faces of the first extrusion, and one or more panels to be mounted to the connecting extrusion(s).

Preferably, the open face of the first extrusion forms an outer edge of the door and there is further provided a blanking extrusion for blanking off the open face of the first extrusion.

DETAILED DESCRIPTION OF THE DRAWINGS t Thus, as shown in Figure 1, a number of different designs of door each have at least two vertical stiles 1 and 2, a top rail 3 and a bottom rail 4. As shown in Figure l(a) the central portion of the door can be filled with a single panel, for example a pane of glass 5, or, u So as shown in Figures l(f) and by a number of smaller panes of glass 6, or other material, mounted between horizontal mounting rails 7 and vertical mounting rails 8. Alternatively, as shown in Figure the horizontLl mounting rails 7 and vertical mounting rails 8 can be used in other ways to produce other designs for glass panes forming the :door, e.g. Federation style.

In another type of door, such as those shown in the remainder of Figure 1, one or more mid rails 9 are used to divide the door into two or three, or possibly more, horizontal portions. Each horizontal portion can have mounted therein a pane of glass 5, or other material, such as shown in Figures l(b) and or can be further subdivided vertically, as shown in Figures 1(c) and Finally, as shown in Figure 1(i) and Figure 1(j) instead of a pane of glass, the panel can consist of a number of slats 10 mounted between the stiles 1 and 2, the mid rail 9 and the bottom rail 4. Of course, it will be apparent, that a top portion of the door could also or alternatively be provided with the slats CSH/565E i' Turning now to Figure 2, there is shown an isometric crosssectional view through a lower corner of a door 11 similar to that shown in any one of Figures l(a) to together with a part of a door jamb 12. As can be seen, the stile 2 making up the door, is formed of an extrusion 13 having a generally H-shaped cross-section defining two closed faces 14 and 15 forming parts of the two sides of the door 11, an outer open face 17 and an inner open face 18. A blanking extrusion 16 is arranged to be connected to the outer open face 17 of extrusion 13 so as to form an outer edge of the door 11. The other open face 18 of extrusion 13 is connected to panels forming the interior part of the door 11, as will be described in more detail hereinafter. The bottom rail 4 of door 11 is formed from the same H-shaped extrusion 13 and is ,held in place by a means of a tie rod 19A extending through the two stiles 1 and 2, as shown in dotted lines in Figure 2. It will be 15 appreciated that connection of the top rail 3 can be accomplished in similar fashion.

~On to open side 18 of extrusion 13, there is mounted a panel mounting extrusion 19 provided with a recess 20 for receiving a glass Spane 21 and two sealing strips 22 and 23. A locking extrusion 24 is mountable in panel mounting extrusion 19 to lock glass pane 21 mounted within sealing strips 22 and 23 into recess A second embodiment of the invention is shown in Figures 3 and 4 in which similar components to that of Figure 2 are numbered with the same reference numerals. In this embodiment, however, the panel mounting extrusion 19 and the locking extrusion 24 are of a slightly different shape to those of the first embodiment, the glass pane 21 being mounted within the recess 20 within a seal 22A and sealant 23A rather than sealing strips. Furthermore, blanking extrusion 26 which blanks off the outer face 14 of extrusion 13 is slightly different to blanking extrusion 16. In blanking extrusion 16 of Figure 2, a central longitudinal recess is provided, whereas in blanking extrusion 26, there are two longitudinal screw recesses 27 and 28 arranged at opposite edges of the extrusion 26. Blanking extrusions 16 or 26 is attached to extrusion 13 which enables the door to be hinged in a jamb.

A third embodiment is shown in Figures 5, 6 and 7, of which Figure 5 is a similar view to those of Figures 2 and 3, FNqure 6 is a i vertical cross sectional view including a top door jamb 31 and Figure 7 q is a horizontal cross-sectional view through a hinge stile and a bottom CSH/565E -6rail of a door. Components similar to those previously described are referenced by identical reference numerals. In the present embodiment, extrusion 13 forming stile 1 is identical to extrusion 13 shown in Figures 2 and 3 and blanking extrusion 26 is identical to blanking extrusion 26 of Figure 3. However, the panel mounting extrusion 29 is different to panel mounting extrusion 19 in that it is shown as having a particularly ornamented shape for aesthetic purposes. A recess 30 is still provided to receive a glass pane 21 and a locking extrusion 24, similar to that of Figure 3, is provided to lock the glass pane 21 into the recess between the bulb seal 22A and the sealant 23A.

To join two glass panes 21 and so as to form the vertical mounting rail 8 there is provided a further extrusion 35 shaped to ,receive two glass panes 21 on opposite sides thereof, which can be locked using the same locking extrusion 24, on either side, as 15 previously described. Also shown in Figure 7 is a door jam 36 to which 99*o :is mounted a hinge 37 on which the door 11 can be mounted.

A fourth embodiment of the invention is shown in Figures 8 and 9. In this embodiment, the door 40 is made up of a first extrusion 41 having two parallel planar members 42 and 43 joined by two parallel connecting portions 44 and 45 extending perpendicularly between the planar members 42 and 43 so as to define an inner open face 46 and an outer open face 47. Thus, the extrusion 41 is similar to the H-shaped extrusion 13, described above, except that it has two connecting portions instead of only one, providing structural stability preventing torsional twisting. The extrusion 41 is cut to the appropriate lengths St to form the rails and stiles of the door, as described above, with the planar members 42 and 43 forming the sides of the door.

The outer open face 47 of the first extrusion 41 is blanked off by a blanking extrusion 48 to form the edge of the door, similarly to blanking extrusion 26 described above. In some c'ses, in order to hold the stiles and rails together to form the door, the blanking extrusions 48 are provided with screw receiving recesses 49 and 50 at the sides thereof, rather than on the main face of the blanking extrusion to enablt the blanking extrusions 48 to be screwed together using screws 51, as shown in Figure 9 at the mitred corners of the door.

However, in order to provide greater stability, the stiles and rails themselves can be screwed together. For example, as shown in Figures 10 to 12, each of the parallel connecting portions 44 and 45 is I CSH/565E -7provided with a screw receiving recess 59. Nhen the extrusion 41 is cut to appropriate length to form the stiles and rails, holes 60 are drilled through the outer one of the connecting portions 45 to allow access to enable a screw 61 to be scriwed through the other of the connecting portions 44 into the corresponding screw receiving recess '59. Thus, the two extrusions at the corner of the door are securely fastened together so that the tie-rod 19A of the previous embodiments is no longer required.

To attach the panels, such as glass pane 21 to the first extrusion 41 in Figures 8 and 9, first 52 and second 53 connecting extrusions are provided which fit together and over the planar members 42 and 43 of the first extrusion 41 so as to cover open inner face 46.

,Seals 54 are provided at the point of contact between the connecting extrusions 52 and 53 and the first extrusion 41. The edge of pane 21 rests adjacent a surface 55 of first connecting extrusion 52 and one r •face of the pane 21 is cushioned against a parallel face 56 of the o ofirst connecting extrusion 52. A locking extrusion 57, having sealing means 58 mounted thereon, is then positioned against the other face of the pane 21 and locks into position in the first connecting extrusion 52 to hold the pane and the two connecting extrusions in place. It o will be apparent, therefore that the two connecting extrusions 52 and o 53 take the place of single panel mounting extrusion 29. This allows o the two connecting extrusions and the pane to be fitted to complete the door from both sides.

25 It will be apparent that each of the extrusions described, can oou~ro have any desired cross-sectional shape, for assembly in the manner described. For example, using only extrusion 13, blanking extrusion 16 s f or 26, panel mounting extrusion 19 or 29 and locking extrusion 24, a variety of different designs of door can be assembled, by simply connecting the various extrusions appropriately. In order to extend the possible designs of doors that can be assembled, to enable a larger number of small panes of glass to be used, the further extrusion 35 for use as the horizontal mounting rail 7 and vertical mounting rail 8 can also be provided.

It will be appreciated that various modifications and improvements can be made to the embodliiients of the invention described above, without departing from the scope of the present invention.
