PANELLING SYSTEM AND PANELLING CLIPS FOR THE SAME

Abstract: A panelling system essentially for use on walls where the first panneling element (upper board 11) is constructed with an undercut along its two undersides, a second panelling element (lower board 12), with a protrusion along both of its side edges, which matches the undercuts (14) on the first panelling element and a third strip-shaped panelling element (52) with an edge thickness equal that of the undercut of the first panneling element (11). On each of said first and second panelling elements there are two or more attachment elements (attachment clips 13), which are constructed for fixing under the panelling elements along at least one side. The attachment elements can be affixed to a surface by screws etc. It is of special interest that the first paneling element has grooves on both sides and the second panelling element corresponding tongues on both of its sides.

Description: Panelling system and panelling clips for the same. The invention relates to a panelling system of the type mentioned in the introduction to patent claim 1, as well as attachment clips for securing such a panelling system to walls, ceilings and floors. Panelling elements are known which have under¬ cuts on each of the side edges and ends where a thinner element which protrudes from the undercut can be engages into the undercut of the opposite adjoining panel. This system rightly enough offers a great deal of flexibility when assembling and combining it with elements above ande below. However it requires extra work to join the tinner elements to the undercuts in the panelling ele¬ ments. If this work is done by the manufacturer, it will reduce the flexibility of the system. The main object of this invention is to create a panelling system which offers as much flexibility in the choice of element combinations as possible, where assembly can be carried out with as little work as possible, parti¬ cularly at the place where it is to be mounted. According to the invention this can be done by designing the panelling system in the manner stated in that part of patent claim \L which characterizes the present invention. In addition, the invention requires attachment elements or attachment clips, ' these are explained in more detail in the sub-claims. Further details of the invention will become evident from the following description of designs and the accompanying reference to the drawings: Figs. 1 and 2 show the perspective drawings of an early design of two matched panelling elements, in accordance with the invention. Figs. 3A and 3B respectively show drawings of the plan and side views of one means of designing, the attachment element, Figs. 4 and 5 show perspective drawings of two alternative ways of designing panelling elements, whilst Fig. 6 shows a section through the various panelling ele¬ ments for use in accordance with the present invention. In its simplest form the invention can be executed in three main elements: An initial panelling element, subsequently calles the upper board (11), which is illustrated in Fig. 1, a second panelling element, sub¬ sequently to be called the lower board (12), which is illustrated in Fig. 2 and an attachment element, subse- quently to be called clips (13), one of which is illustrated in Figs. 3A and 3B. The design of the indi¬ vidual elements and their use are described in more detail below. There is also a more detailed description of the invention and different variations on the basic design. The upper board (11) has an undercut (14) and an equivalent ribbed edge (15) on each of its long sides. The thickness of the undercut (14) is determined by the system and is the same for all upper boards (11), The thickness of the upper board (11) can however vary from a minimum thickness which is determined by the ribbed edge (15) having sufficient strength upto a reasonably large thickness. In the example, the upper board is shown with a smooth outer surface. An alternative design could consist of mouldings and/or a surface structure as required. One end of the upper board (11) has an under¬ cut (16) and an equivalent ribbes edge (17), as on the long sides. At the other end, the upper board (11) has an upper joint (18) which matches the ribbes edge (15). Consequently, at that end there will be a joint-feather ot tongue (19) at the base of the upper board. The upper board (11) can be manufactured using standard techniques such as planing and edge milling. If undercuts (14) of a standard thickness are used, perhaps possibly a standard width as well, manufacturing would ve both rational and inexpensive. In the example, upper board (11) is attached to two battens (20) and (21). On one side, the upper board is held in position by means of a flange-shaped attachment element or clip (13A), which is fixed by screw (22) to the underside of the upper board which is atached to an adja¬ cent board (not shown). On the other side, on the right of the figure, there are equivalent attachment elements (13B) and (13C) respectively. These are attached to the lower board by screws to their respective battens (20) and (21) at this point by screws (24). By using clips (13) the overall assembly of the panelling elements is simplified. The use of visivle nails or other means of attachment is avoided. In addition, one vaoids cracking which so frequently occurs with nailing. Further, the panelling can easily be removed without damaging or destroying any of the parts. The clips (13) and the manner in which they are used will be described below. Fig. 2 shows an example of the other paneliing element, the lower board (12). The term "lower board" is used because this element has a lower tongue (25) on each long side. The thickness of the tongue (25) equals the thickness of the undercut (14) on the upper board so thatm the tongue (25) can be held under this and be kept in position by the adjacent elements. The end profile of lower board (12) is the same as the profile of the upper board (11), i.e. with a marked ribbes edge (17) at one ende and a marked tongue (19) at the lower end of the other. The lower board (12) in Fig. 2 is shown with the same thickness as upper board (11) and has a smooth outer side. The thickness can also vary from a minimum thickness which equates being largely determined by the economic and weight considerations of a lower board. The outer surface can be moulded and given a structure as required. If a lower board (12) of the minimum thickness is to be used,this boarding can be manufactures from a plate such as plywood. The thickness must sufficient to allow the attachment of the clips (described below). If thicker lower boarding (12) is to be used, it will be most usual to edge mill a suitable type of wood, as described above for the upper boards (11). An alternative way of manufacturing the upper and lower boards, shown in Figs. 1 and 2, is binding the matching plate strips together with an adhesive. They can consequently be manufactures from an inexpensive material in a simple, economic fashion. The lower board (12) is held in position on one side by fitting under an upper board which is not shown. On the other side, on the right of Fig. 2, it is atached in the same manner as upper board (11) by two clips (13D) and (13E) which are affixed to battens 26 and 27 respectively. Figs. 3A and-3B respectively show the plan and side views of the attachment element or clips (13) which can be used as shown in Figs. 1 and 2. The clips (13) which are manufactures from a band-shaped steel material of suitable strength, are about 55 mm long and about 12 mm in width in the example. Along the mid axis of the clip there are five holes at roughly the same distance from each other. The three holes at one end (28,29 amd 30) from one end inwards respectively, and hole (31) at the other notch for the heads of screws. Two holes at one end, (28,29) hvae this notch on one side of the clip, whilst the other two holes, (30,31) have their notches on the opposite side. The reason for this will be evident (below). In addition, there is a square hole (32) stamped in such a manner that four flaps (33) protrude from the same side as the material extending from the adjacent holes. (30,31). The flaps (33) have the function of being pressed into the wood of a panelling element and are kept in position by a screw through the end hole (31). Furthermore, once this screw has been secured, the flaps (33) will prevent the clip (13) from turning around the securing screw (not shown in Fig.3). As the figures show, the outer hole (28) as a minimum protrudes from the panelling element, either upper board (11) or lower board (12). This means that the hole (28) can be used for screwing or nailing the two panelling elements (11,12) to the surface below. The clips (13) have been made pointed at both ends so that they can be driven into wood, when for instance attachment is to be made in corners in the manner described below. This means that the clips must be manu¬ factures from a steel alloy of suitable rigidity. Figs. 4 and 5 respectively show alternative means of designing the upper board (11) in Fig. 1, and the lower board (12) in Fig. 2. Panelling element 34 in Fig. 4 is moulded using a known procedure (the TG principle) with a groove (35) on both of its long sides. Panelling element (36) in Fig. 5 matches, and has a tongue (37) along both of its long sides. Consequently, this design can be used for floors or walls, where a flat outer surface is required. These borads can also be manufactures with moulded edges* for wall panelling. The end mouldings are the same as the end mouldings used for TG panel. When using this panelling system which accords with the invention, a number og extra elements can be employed in addition to the basic elements illustrated in Fiqs. 1-5. Fig. 8 shows how the different upper and lower boards can be joined when panelling walls. First, two or more upper boards (11) or lower boards (12) can be joined lengthwise. This allows panelling to be adjusted to diffe- rent roof heights in a modular system, e.g. of 5 cm, made up of different boards. Second, lower boards of different design can be used, e.g., plate-shaped (52), as shown at the left of Fig. 8, or the equivalent shape (12), shown in Fig. 2 at the right of the figure. In the latter case, lower board 12 can be joined lengthwise. Apart from this, different widths of the various panelling elements can be employed in combinations of the differently shaped elements, e.g. dissimilar widths and structure or differing lengths and widths. This means enormous possibilities for variation within acceptable economic limits. It is therefore not only possible to adjust the panelling system to different roof heigths and wall widths etc. without capping or special adjustmens, it is also possible to make walls and ceilings in accordance with individual taste regarding structure and pattern. The panelling system which accords with the invention can be manufactures in a relatively small number of elements, including different lengths, yet nevertheless offers 10 million combinations for any parti¬ cular wall. If the panelling elements are designed in the manner shown in Figs. 4 and 5, the system can also be used for floors in the same way as it is used for ceilings and walls.
