Description

Skirting board system

The present invention concerns a skirting board system comprising skirting boards for quick and simple mounting as defined by the preamble of claim 1.

Background Traditionally skirting boards has been mounted by techniques like nailing, pinning and gluing. Skirting boards has traditionally been nailed or glued and wooden skirting boards have to a limited extent been subject of systematical improvements with regard to mounting techniques. Synthetic skirting boards are commonly provided with a backside having glue strips covered by foil to be removed immediately before mounting. In a number of applications it may be preferred to use skirting boards where the attachment method is more prepared or systematized, especially for wooden skirting boards.

In addition there are some skirting board systems that are relatively complex and typically comprise rails or other substrate that are attached to the wall and a front piece, the actual skirting board, which is hung, clipsed or otherwise attached to the substrate, covering the latter after mounting. Some skirting board systems also comprise voids adapted to house electric cables or the like. Skirting board systems as discussed above are known from GB 2317 628, GB 2321 478, EP 1529 897, WO 06032 262, and US 2006 080925.

In connection with mounting of doors and windows in openings for such purposes, adaptation of linings, platbands and skirting boards are particularly time consuming and much work can be saved by providing a system for the skirting boards in such cases.

It should especially be mentioned that mounting kits have been developed or mounting of doors and windows for easy adaptation to varying wall thicknesses. Especially in such connections there are large potential benefits in using a skirting board system that is particularly adapted to the specific use and which may be attached to the relevant substrate, that being either woodwork, concrete or different kinds of plate materials, e.g. made in synthetic materials, lightweight concrete or other materials.

Generally speaking it is desirable that the mounting is as simple as possible, as easy as possible, provides a lasting attachment when the skirting board is affected only in the manner in which it is intended to be, but at the same time being simple to release without harming the skirting board when that is desired. GB patent No. 2 365 955 teaches a skirting board system where the skirting boards are arranged to be pushed onto a pre-milled groove in the back side of the skirting board. This system requires milling of a groove in the wall surface or alternatively that sprigs are pre-attached to the wall at exactly the right height to match the height of pre-milled grooves in the back side of the skirting boards.

CN publication No. 201474267 describes a system for attachment of skirting boards by pushing the skirting boards on to sprigs that extend from plates that are attached to the wall by screw(s). As seen from drawing, it is not required with an exact match of height for the plate attached to the wall, but attachment of a number of plates to the wall before the skirting board can be attached, involves a number of work operations that it would be beneficial to avoid. In concrete walls one must also typical use plugs in addition to screws for attachment of the plates.

It is thus a need for improvements in this area to make mounting of simple skirting boards simpler and quicker without jeopardizing the force of the attachment to the substrate. Objectives

It is an object of the present invention to provide a skirting board system which takes account for the desire of simplicity and rapidness when mounting simple skirting boards. This is relevant for skirting boards between floor and walls as well between ceiling and walls and other wooden skirting boards to cover vertical or horizontal joints between building elements.

It is furthermore an object to provide a skirting board system by which simple skirting boards are easy to mount in a safe and quick manner for a lasting attachment but which still allows disassembly without harming either the skirting boards or the substrate.

It is a particular object of the invention to provide a skirting board system which is suitable for use when mounting doors or windows in frames that are particularly designed for such purpose, by being arranged for adaptation to different wall thicknesses.

The present invention

The above mentioned objects are achieved by the present invention which concerns a skirting board system as defined by claim 1. Preferred embodiments of the invention are disclosed by the dependent claims. In general the present invention concerns a skirting board system which is comprised by preferably wooden skirting boards, preferably made in wood, wood fibers or other wood based or wood like materials, provided with a milled or otherwise provided, recess groove at the back side of the skirting board, as well as double-sided sprig plates arranged to be attached to the skirting board by one of its sides and to be attached to a wall or other substrate by the opposite side.

The plate part of the sprig plate typically has a thickness corresponding to the depth of the groove into the skirting board.

Additional attachment techniques may be employed in some embodiments, particularly glue in the form of glue pads that may be positioned in the same grooves as the sprig plates or in grooves particularly intended for glue pads. In addition or alternatively, glue may be employed to one or both sides of the core of the sprig plates.

The skirting boards may also be provided with particular grooves intended for receiving a continuous sealing running the entire length of the skirting boards. Such sealing may typically seal against penetration of moisture to the back side of the skirting board, but may also contain a flame retardant sealing. Such a sealing may be with or without a layer of glue. In some embodiments there may be a number of recess grooves at the back side of the skirting board, for instance such that an intermediate groove is intended for a continuous sealing, surrounded by grooves of which at least one is intended for holding sprig plates according to the general and mandatory aspect of the invention, while the other grooved may be arranged to receive a desired number of either sprig plates, glue pads or both.

For the attachment of the skirting board to a wall or other substrate, there is typically a two-step procedure. First the sprig plates are attached in a desired number and mutual intervals along the grooves of each skirting board. A tool particularly designed for the purpose allows the sprig plates to be attached with one simple blow against the tool The material of the sprig plates is adapted to the substrate in question and if required to the material of the skirting board as well.

The sprig plates can alternatively be attached during production and be provided with a protective sheet of cardboard or the like for storage and transportation. Detailed description of the invention

Below the invention is described in further detail with reference to non-limiting examples of embodiments which are illustrated in the enclosed drawings, in which:

Figure la shows schematically the back side of a skirting board according to the present invention. Figurelb shows a side sectional view of the skirting board of Fig. la at the dotted line.

Figure 2 shows enlarged a double-sided sprig plate according to the present invention .

Figure 3a shows schematically the back side of a skirting board according to the present invention in an embodiment different from the one of Figure la.

Figure 3b shows a side sectional view of the skirting board of Figure 3a.

Figure 4a shows schematically the back side of a skirting board according to the present invention in an embodiment different from the one shown in Figures la and 3a.

Figure 4b shows a side sectional view of the skirting board of Figure 4a.

Figure 5 shows a side sectional view of the skirting board from Figures 4a and 4b with a lining assembled thereto.

Figure 6 shows schematically the skirting board and the lining from Figure 5 used in a certain connection.

Figure 1 shows the back side of a skirting board 11 with a recessed groove 12 extending the entire length of the skirting board. The groove is located in distance from both longitudinal edges but need not be centered between these. In the groove 12 sprig plates 13 are arranged spaced apart from one another.

Figure lb shows a side sectional view of the skirting board 11 from Fig. 1. The skirting board exhibits a profiled front side and a plane back side except for said groove 12. The sprig plate 13 is attached at the bottom of the groove by means of sprigs extending outwards in a direction to the right in the drawing and attached to a substrate 10, such as a wall surface, by means of sprigs extending to the left in the drawing.

Figure 2 shows the sprig plate 13 enlarged in a side sectional view. It has a core 131 which is a substrate holding sprigs 132 extending from one side 133, denoted the skirting board side, and sprigs 134 extending from side 135, denoted the substrate side. The length of the sprigs 132 can vary in accordance with the thickness and material of the skirting board 11 and the length of the sprigs can also vary in dependence of the type of wall material, as well as the dimensions and weight of the skirting board, but also in dependence of other, outer factors. The thickness of the core 131 is typically about equal the depth of the recess groovel2 such that it fills the groove but not extends out of the groove 12. The sprig plate 13 is said to be double-sided due to the fact that sprigs extend from both sides of the core 131. The double-sided sprig plate 13 typically has a rigid core 131 in a desired hard material, preferably a synthetic material in a quality ensuring that sprigs not easily can penetrate the core. The core 131 is preferably made in a material harder than the material of the skirting board and harder than the substrate in the form of a wall or the like that the sprigs are to penetrate. The sprigs 132 on the skirting board side for penetration of the skirting board 11 at the bottom of the recess groove 12 typically have a length in the range 3-7 mm, while the sprigs 134 on the substrate side 135 typically have a length in the range 5-15 mm.

Figure 3a shows an alternative embodiment compared to the variant shown in Figure la. The skirting board 1 in Figure 3a exhibits two grooves 12 that are principally equal and may be used for the same purpose. Sprig plates 13 may thus be arranged at intervals in both grooves 12 as shown by the drawing. Figure 3a also shows glue pads 14 or strips arranged at intervals in both grooves and alternating between the sprig plates 13. The use of glue pads is not mandatory, however, and if such are used they may be used in a number different from the number of sprig plates. It is also an option to use sprig plates in only one groove and glue pads in a different groove only. Glue pads are pads with glue on both sides and can in its simplest form be a double- sided tape.

Figure 3b shows a side sectional view of the skirting board 1 from Figure 3a along the dotted line. As evident from Figure 3b the skirting board 11' has a non-profiled front side which naturally is within the scope of the invention. Figure 4a shows yet another alternative embodiment of a skirting board according to the present invention, here denoted 11". The skirting board 11" has four longitudinally running grooves at its back side, of which the second and the fourth groove are shown having sprig plates arranged interspaced, such as also in Figure 3a. Third groove from above is filled with a longitudinal sealing 15 extending uninterrupted through the entire length of the skirting board 11". This may be a sealing which is waterproof, diffusion tight, which comprises flame retardant material and/ or is specifically designed to stop insects or pests of different kinds.

Figure 4b shows the skirting board 11" in a side sectional view along the dotted line in figure 4a.

Figure 5 shows a constellation or use of a list 11" in a certain connection. In the upper of the grooves 12 a lining 16 is shown rigidly attached in the uppermost groove 12. The lining 16 typically has the same extension lengthwise (into the paper plane) as the skirting board 11". Together the combined skirting board and lining constitutes a unit which is suitable for lining and covering e.g. around windows and doors. The unit comprising skirting board and lining can either be prefabricated or be assembled of a carpenter at the site of use. By suitable joining techniques the two are joined prior to mounting. Most conveniently certain lengths of these units are prefabricated comprising joined skirting board and lining, since machine made joining will be quick and ensure a lasting binding between the two elements 11 and 16.

It should also be mentioned in connection with Figure 5 that even if two of the grooves 12 are shown "empty", these can in the same manner as shown in Figure 4a contain either a continuous, longitudinal sealing 15, glue pads 14 at certain mutual intervals, further sprig plates 13 or a combination of said elements. It should also be emphasized that the variant shown in Figure 5 not requires use of a skirting board 11" having four grooves 12, it is sufficient with one extra groove as shown in Figures 3a and 3b if there is no need for a continuous sealing 15.

Figure 6 shows a side sectional view of the combination of skirting board 11" and lining 16 in a particular connection, namely in a system in which the elements 11" and 16 are included as part of a frame 20 for windows or doors. Such a frame 20 as shown in Figure 6 comprises a first or primary frame part 17 which is secured to wall by means of a screw 19 in the opening for a door or a window. Furthermore it comprises a secondary frame part 18 which is extendable in relation to the primary part 17 and fixated to this in desired position by means of fixation screw 21, the position being determined by the wall thickness. The secondary frame part 18 has a reception member 22 arranged to receive and fixate the lining 16 of the combined element consisting of lining 16 and skirting board 11". The reception member 22 may be arranged to fixate the lining 16 in a definite position, in certain steps or in a step-less adjustment of engagement between lining 16 and reception member 22. The fixation can be made in many different ways and is not illustrated. For instance, it may be made by a through running bolt, by means of a fixation screw corresponding to fixation screw 21 or in any other suitable way, preferably in a way which may easily be released and reattached. If a reception member 22 allowing a number of different positions for the lining 16 is used, the versatility of the frame 20 is increased, i.e. that it may be used for a larger variation of wall thicknesses than would else have been the case. Figure 6 furthermore shows use of a continuous sealing 15 in connection with the skirting board 11" as well as the mandatory sprig plates 13.

As also shown by Figure 6 the primary part 17 of the frame 20 comprises a profile 21 which corresponds to the skirting board 11". This is naturally not mandatory, nor is the use of sprig plates 13 and sealing 15 between the primary part 17 and the wall. The sprig plates may be attached to the skirting board either at fabrication or at the site of use. If they are attached at the user site, it is convenient to use a particular tool for obtaining a simple attachment. An impact piece that comes to rest against the core 131 of the sprig plate 13 without being in touch with any one of the sprigs 135 and which is suitable for being hit by a hammer, will be a suitable tool for this purpose. The invention is, however, not limited to any particular way for attachment of sprig plates to the skirting boards. The sprig plates 13 can also be positioned in the groove of the skirting board and be lightly pushed against the skirting board without full penetration of the sprigs 132 in the skirting board 11. Only when the skirting board is placed against the substrate and pushed against this with force, the sprigs 132 will fully penetrate the skirting board 11 in the bottom of the groove 12, while the sprigs 134 more or less simultaneously penetrates the substrate, for example a wall.

Above the possibility of using particular glue pads in addition to the sprig plates 13 is mentioned. It is also a possibility to apply glue to the sprig plates so that these bind both by the sprigs engagement with the substrate and skirting board respectively, but also by an adhesive effect between the core and the substrate and/ or the core and the skirting board. If e.g. glue is used on the side of the core material facing the skirting board but not on the side facing the substrate (wall) this will ensure that the sprig plates remain attached to the skirting board if the skirting board is sometime later pulled free from the substrate, such as a wall. Lack of glue between skirting board and certain type of wall surfaces, such as wall surfaces provided with wall paper, ensures minimum damage to the wall if the skirting boards should at some point in time be removed.

It is worth noticing that when the claims refer to skirting board 11 this also includes the variants discussed above, denoted skirting board 11' and skirting board 11".
