Description
Improvements in or Relating to Doors
This invention relates to doors.
Metal, and more particularly steel, doors are known in the architectural, building and construction trades.
In general they are economic to produce and it is easier to produce a steel fire door having a two-hour rating than a timber door. In addition, steel doors are capable of higher levels of security. However the appearance and operation of steel doors has meant that architects tend not to specify steel doors except in industrial applications where appearance is not an issue.
According to one aspect of the present invention there is provided a door having first and second major sides, at least one of said major sides being formed from metal and having a selected portion extending continuously with straight edges the length (or width) of said one major side, which selected portion is not in the same general plane as the remaining portion or portions of said one major side.
Preferably said selected portion is recessed relative to said remaining portion or portions. Conveniently the plane of the selected portion is parallel to said general plane of said remaining portion or portions.
In an alternative arrangement the selected portion could be angled relative to the general plane of said remaining portion or portions.
In preferred embodiments there are right angled steps between the selected portion and the remaining portion or portions.
In other arrangements there is more than one selected portion on said one major side and in more preferred embodiments both major sides are formed from metal with one or more selected portions.
Some arrangements may have one or both edges of the selected portion parallel to the edges of the door in the continuous direction of the selected portion or one or both edges of the selected portion are angled relative to the edges of the door in the continuous direction of the selected portion.
Preferably each major side is formed from a single piece of sheet metal which is folded. In addition the oppositely disposed edge portions of the metal sheets in the continuous direction of the selected portion are folded so that the two major sides are interconnected in spaced relation to each other.
Conveniently end pieces are provided between the interconnected edges.
In further preferred arrangements the space between the two major sides incorporates strengthening.
Conveniently the strengthening is in the form of a honeycomb infill of a suitable material.
Preferably the selected portion is adapted so as to enhance its appearance. Panels may be attached by adhesive or the surface may be polished or textured according to taste. The panels may for example be a timber veneer or a laminate. Glazing may also be installed in the selected portion or the remaining portion or portions.
According to a second aspect of the present invention there is provided a method of forming a door comprising the steps of bending two metal sheets so that both sheets provide a major side and at least one major side has a selected portion extending continuously with straight edges the length (or width) of said one major side, which selected portion is not in the same general plane as the remaining portion or portions of said one major side, and so that both sheets are formed at oppositely disposed door edges in the direction of the selected portion with means for interconnecting the two sheets so that the two major sides are spaced relative to each other.
Preferably the bending is effected in a sheet metal bending jig.
Embodiments of the present invention will now be described in more detail. The description makes reference to the accompanying diagrammatic drawings in which:
Figure 1 is a horizontal, part cut away sectional view of a door according to the present invention.
Figures 2, 3 and 4 show in section various infill options for the door shown in figure 1.
Figures 5, 6 and 7 show front views of the general options of basic doors according to the present invention.
Figures 8, 9 and 10 show sectional views of alternative basic door arrangements according to the present invention, and
Figure 11 is a front view of a further door embodiment according to the present invention.
Figure 1 shows a section through a door 10 which has two major sides 11, 12. The sides 11, 12 are formed from respective sheets of metal 13, 14 for example steel, by bending. The bending is effected in straight lines using a simple jig which bends the metal sheet a chosen amount about a member which is set at a chosen location on the sheet. The member may be in the form of a sharp edge or may be shaped.
Provision is also made for bending the sheet back on itself.
The opposite edges 15, 16 of the sheet 13 are simply bent back on themselves. The opposite marginal portions 17, 18 of the sheet 14 are bent at right angles to form side walls 19, 20 for the door and at right angles again to produce feet 21, 22 which are bent back on themselves. The feet 21, 22 can be simply interconnected with the edge 15, 16 of the sheet 13 so as to connect the two sheets 13, 14 together. Preferably an infill is provided between the two sheets. This infill can be provided for strengthening and/or insulation. A 'honeycomb' infill has been found to be particularly desirable.
Preferably end sections (not shown) are provided to close off the open ends of the door but their form is not relevant to the present application. Also the interconnection of the two sheets can be modified in any number of ways. The two sheets could also be simply welded or screwed to spacer members along the edges of the door or indeed welded or screwed to each other. It is also possible for the door to comprise only one metal major side suitably joined to say a wooden door to improve its fire rating.
The major sides 11, 12 of the door shown in figure 1 are both formed with recesses 23, 24. In the arrangement shown the recesses 23, 24 are formed by a series of right-angled bends but it will be appreciated that other bends would be suitable. The recesses 23, 24 can be of any width and can be positioned in any desired location across the width of the door as indicated by the incomplete lines in the figures.
An infill 25 may be provided in the recess by adhesive for example. In Figure 2 the infill is in the form of a coloured push-plate or kick-plate which could be welded or screwed to the door. In Figure 3 a laminate or veneer is applied to the recess. In Figure 4, corian or timber is secured in the recess. It will of course be appreciated that any suitable material can be put in the recess or the surface of the recess can be altered by known machining techniques. All or only part of the recess can be thus adapted. It is also possible to apply these techniques to alter the appearance of the remaining parts of the sides 11, 12 of the door either in addition to or instead of the recess.
The infills 25 can be appearance enhancing in the form of natural materials, such as wood veneers, granite or other stone, or artificial materials, such as plastic laminates, metal sheets. The infills could also be performance enhancing using acoustic, thermally insulating or fire resisting materials. The infills could also be a mixture of both types. The infills may also be in the form of signs which may be of any size, even full recess size. Such signs would give a desirable built in effect.
Figures 5, 6 and 7 show the basic forms of bend that can be applied to the sides 11, 12 of the door.
Obviously, one side can be left plain if desired. In
Figure 5 there is a simple recess 23 having two straight edges 26, 27 parallel to the edges of the door. The edges 26, 27 can be as close to the edges of the door as the bending process will allow.
Experience has shown that 30mm is a practical distance from the edge but smaller distances are possible.
Both edges must extend continuously from the top to the bottom of the door.
In Figure 6 the edges 28, 29 of the recess 23 are both angled relative to the edges of the door. The size of the angles is a matter of design choice but both edges 28, 29 must of course extend continuously from the top to the bottom of the door.
In Figure 7 there is shown a combination of an angled edge 30 and a straight edge 31.
It will be appreciated that the design possibilities are endless. The system is also enhanced when double doors are required.
Figure 8 shows a door 10 incorporating the recess 24 in side 12 but side 11 is formed with a projection 32 instead of recess 23. This is clearly simple to produce using the techniques described above.
Figure 9 shows two further developments. The side 11 of the door is formed with two recesses 33, 34. of course these recesses 33, 34 could be of any size, in any position and could number more than two. The other side 12 of the door is formed with a simple step 35.
Two further examples are shown in Figure 10 in which the side 11 has a recess 36 which has one right angled edge 37 but the recess has an angled surface 38 extending to the general plane of the side 11. The other side 12 of the door is formed with a recess having two angled walls 39, 40.
It will of course be appreciated that the formation may extend widthways of the door rather than lengthways of the door. The formations also add rigidity to the major sides of the door.
Figure 11 shows a further modification in which a glazing panel 41 is incorporated in part of a symmetrical back to back recess arrangement 13, 14.
Similar glazing panels could be incorporated in the non-recessed portions of the door.
