Description

CLOSURE MEMBER AND METHOD OF CONSTRUCTION The present invention relates to a closure member and a method of constructing a closure member and is concerned particularly, although not exclusively, with a closure member for a building structure and a method of manufacturing the same.

A traditional style of door for use in a house or other building structure, is of a timber construction having one or more panels of timber and/or panes of glass in a timber frame. The panels are conventionally held in the door between vertical and horizontal frame members by a traditional mortise and tenon construction and any panes of glass are held in the frame against a rebate by a wooden bead or by putty. The assembly of the door is therefore labour intensive and necessarily time consuming.

Nevertheless, such doors are attractive and desirable, mainly because of the raised and recessed features created by the panels.

An alternative known door which is much cheaper to produce comprises a plurality of strips of timber, glued together to form a rectangular laminated core which is then covered on each side by a rectangular piece of plywood. The resultant doors are strong but substantially featureless and therefore less attractive than the traditional timber doors. A known method of enhancing the relatively bland appearance of such doors is to mount strips of wooden bead on to the surface of the door in a rectangular outline to give the appearance of one or more panels. However, this method only permits a raised profile and, since no recess is possible, the panel effect is not convincing.

Figure 10 shows a door frame according to an alternative embodiment of the invention; Figure 11 shows the door frame of Figure 10 with additional frame members and panels; Figure 12 shows in sectional view along line A-A' of Figure 11 a portion of the door frame of Figure 11; Figure 13 shows an alternative door construction; Figure 14 shows in front view the door of Figure 13, Figure 15 shows, in sectional view along line B-B' of Figure 14 a portion of the door of Figures 13 and 14, and Figure 16 shows in sectional view an alternative embodiment of the door of Figures 13 to 15, incorporating a glazing element.

Referring to Figure 1, this shows generally at 10 an aluminium construction frame for a door. The frame 10 comprises a plurality of hollow aluminium sections 11, which are connected together by screws (not shown). The configuration of the door frame 10 may vary according to the required design, but the example shown in the Figures comprises, in addition to two upright sections lia, a top llb and a bottom section lic, three horizontal spars lid.

Figure 2 shows in part-sectional view a corner of the frame 10, from which it may be seen that the sections 11 comprise hollow box sections, in which a pair of parallel sides extend in both directions beyond the box, in a conventional girder shape. The outer corners of the frame are mitred and are connected by angle brackets 12.

Figure 3, and Figure 4 which shows in more detail the corresponding corner to that shown in Figure 2, show the aluminium frame 10 with the addition of timber key members 13. The key members 13 comprise timber strips, which engage the frame sections 11 and are held in engagement by adhesive (not shown). The key members 13 engage the frame section 11 on both its interior and exterior edges.

Figure 5 shows in cross-section part of the frame 10, taken along lines A-A' of Figure 3. At this stage of construction a timber facing element 14 is fixed to the key members 13 using adhesive (not shown). The facing element 14 has grooves 14a which engage tongues 13 formed in the key members 13.

Figure 6 shows the next stage, in which the frame 10 is inverted and a panel 15 is made to engage the key member 13 and facing element 14 again using adhesive (not shown). A second facing element 14 is then placed over the other side of the frame to engage the key members 13 and panel 15 with adhesive. The panel 15 comprises a composite panel having a timber core 1Sa and timber laminates 15b on each side. The door is then placed in a press in which the above-described components are pressed together.

The next stage of construction is shown in Figure 7, in which an edge of the door is machined to the required profile, by cutting an edge of the facing elements 14, and the key member 13. In addition, a pair of grooves 16 are cut in the panel 15.

Figure 8 shows the penultimate stage of construction in which bead members 17 are placed in the grooves 16 and held there by adhesive. The purpose of the bead members 17 which may be of any chosen profile, is to give the door the appearance of traditional construction in which the portions of the panels 15 not covered by the bead 17 appear as traditional timber panels.

Figure 9 shows the completed door in which a moveable locking member has been mounted in a casing 19, which itself extends within the frame section 11. The locking member 18 is therefore securely mounted in the door, and may not easily be broken or split from the door, in contrast to doors of conventional construction.

A door constructed in the manner described above, has the advantage of being stronger than conventional doors, and is also less likely to warp or otherwise deform, due to the rigidity of the aluminum interior frame. In addition, the door is of relatively lightweight construction, whilst still retaining the aesthetic appearance of a traditionally constructed door.

The frame itself, and the configuration of the panels and the bead numbers mounted on the panels may be varied according to requirements, whilst still using the basic construction method described.

Referring particularly to Figure 10 this shows generally at 110 a timber door frame of traditional construction. The door frame 110 comprises peripheral frame members alia, glib, lllc and ilid and an internal frame member ilie. The frame members are joined together using conventional mortise and tenon techniques. On inner edge surfaces of each of the frame members lila, glib, lllc, llld and ilie are provided grooves (not shown) for receiving further frame members and panel members as described below with reference to Figures 11 and 12.

Turning to Figures 11 and 12 these show a door comprising the frame of Figure 10 with additional internal frame members 112, 113 and 114 together with small wooden panels 115, 116, 117 and larger wooden panels 118 and 119 and corner members 120 and 121. Around the periphery of wooden panels 115, 116, 117, 118 and panels 118 and 119 are bead trim members 122.

The internal frame members 113 and 114, the panels 115, 116, 117, the larger panels 118, 119, the corner members 120, 121 and the bead members 122 are all attached to the basic frame members lila, glib, ilic, ilid and llle in the manner shown in Figure 12.

Figure 12 is a sectional view along lines A-A' of Figure 11. The panel 116 is secured in the frame member llld by a mounting member 123 which is made of cork material and is of the size and shape of a biscuit. The "biscuit" connector 123 is first placed in a groove 124 in the frame member lild whereupon the panel 116 is placed on the edge of the frame member lild such that groove 124 of the frame member ilid aligns with a groove 125 in the edge of the panel 116. The panel 116 is then slid along the frame member lild such that the groove 125 engages the biscuit connector 123 in a friction fit.The panel 116 is thus secured to the frame member slid. Bead members 122 are then secured to the panel 116 by placing the bead members 122 in grooves in the panel 116 and adhereing the bead members 122 to the panel 116 by adhesive (not shown).

In a similar way the panels 115, 116, 117 and panels 118, 119 are secured to their neighbouring frame members and the bead members 122 are attached to their respective panels or frame members. In addition the frame members 113 and 114 are secured to the frame members lild and 111e in the same manner such that the finished door comprises a plurality of panels with beaded trim in the style of a traditional door.

However, the above described method of assembling a door is much less labour intensive, and therefore much cheaper, than traditional methods of securing panels and internal frame members using mortice and tenon joints. It will be understood that, although the door depicted in Figure 11 has three small wooden panels and two larger wooden panels, a door may be constructed by the abovedescribed method which has a different combination of panels and if required a different combination of internal frame members. Furthermore, if glass panes are required then these can be incorporated in the door frame by making one of the bead members 122 act as a rebate against which the glass pane can bear. In such a case, the bead member is attached first to the frame member, for example, by locating in a groove in the bead member a tongue of the frame member.The glass panel can then be secured in place either by attaching a bead support member to the rear of the frame, behind the glass, for example, by screws or other releasable fixing means.

Figure 13 shows an alternative construction of door generally at 127. This door comprises a plurality of timber core members 128 which are placed edge to edge and held together by adhesive (not shown). A pair of plywood sheets 129a and 129b are placed on inner (129b) and outer (129a) faces of the door over the core members 128 and are attached to the core members 128 by adhesive (not shown).

To give the appearance of panels on the outer surface of the door 127 a number of grooves 130 are cut in the surface through the plywood sheet 129a and underlying core members 128 using conventional router techniques.

In to the grooves 130 are placed wooden profile members 131 which are secured in place by adhesive (not shown). When the grooves 130 and profile members 131 are arranged in a rectangular pattern on the surface of the door 127 the effect is that of a panel. Figure 14 shows a part finished door having three such "panels" 132, 133 and 134. The surfaces of the panels 132, 133, 134 are actually the plywood surface 129a of the door shown in Figure 13 but appear as panels because of the arrangement of profile members 131. Figure 15 shows in cross-section a portion of the profile member 131 and plywood sheet 129a taken along the line B-B' of Figure 14. In this way an arrangement of "panels" can be made on the surface of the door 127.The grooves 130 can be cut out of the blank doors 127 automatically by machines according to the desired pattern and the profile members are then cut to length and glued in place in the grooves 130 to form the "panels".

Figure 16 shows an alternative embodiment in which a glazing unit 135 is incorporated in the door. In this embodiment, a hole is cut in the door 127 and rebate profile members 136 are secured along the edges of the hole such that the glazing unit 135 can bear against them.

On the inside of the door the glazing unit 135 is held in place by a bead 137 which is screwed or otherwise releasably secured to the door.

Since the blank door 127 may be produced cheaply and of relatively inexpensive materials, and since the process of cutting the grooves 130 can be achieved automatically using CNC machines, a panel effect door can be manufactured at much less cost than by using traditional techniques.

The doors described above have the additional advantage that, being made from fewer, and in many cases smaller, components than conventional doors they are less susceptible to changes in size due to the effects of weather. Dimensional stability is therefore improved.

Also, the above described constructions are more secure than many conventional doors.

It will be apparent to the skilled person that various modifications may be made to the invention without departing from its scope.
