Definitions

  • the invention generally relates to the field of flooring systems comprising laminated floor panels, which could be installed in advanced patterns especially such floor panels, which are possible to lock and unlock with mechanical locking systems.
  • the invention concerns an improvement of the flooring system and panels described in WO 03/089736, which is incorporated as reference.
  • the present invention is particularly suitable for use in floating floors, which are not attached to the sub floor and which are formed of floor panels joined mechanically with a locking system integrated with the floor panel, i.e. mounted at the factory, are made up of one or more upper layers of printed and structured materials such as decorative laminate or decorative plastic material, an intermediate core of wood fibre based material or plastic material and preferably a lower balancing layer on the rear side of the core.
  • the invention can be used in any floor panel and it could be combined with all types of known locking system, where the floor panels are intended to be joined using a mechanical locking system connecting the panels in the horizontal and vertical directions on at least two adjacent sides.
  • the invention can thus also be applicable to, for instance, solid wooden floors, parquet floors with a core of wood or wood fibre based material and a surface of wood or wood veneer and the like, floors with a printed and preferably also varnished surface, floors with a surface layer of plastic or cork, linoleum, rubber or similar. Even floors with hard surfaces such as stone, tile and similar are included and floorings with soft wear layer, for instance needle felt glued to a board. The principle could also be used on floors, which are glued or nailed to the sub floor.
  • Laminate flooring usually comprising rectangular floor panels with a core of a 6-12 mm fibre board, a 0.2-0.8 mm thick upper decorative surface layer of laminate and a 0.1-0.6 mm thick lower balancing layer of laminate, plastic, paper or like material.
  • a laminate surface comprises a printed melamine impregnated paper, which is pressed with an embossed sheet.
  • the most common core material is fibreboard with high density and good stability usually called HDF - High Density Fibreboard. Sometimes also MDF - Medium Density Fibreboard - is used as core.
  • Traditional laminate floor panels of this type have taken a large market share mainly due to the fact that advanced printing and pressing technology has made it possible to make very natural copies of mainly wood parquet floorings. Laminate floorings look like wood, but are more durable and less expensive than wood floorings.
  • These systems comprise locking means, which lock the panels horizontally and vertically.
  • the mechanical locking systems are usually formed by machining of the core of the panel.
  • parts of the locking system can be formed of a separate material, for instance aluminium or HDF, which is integrated with the floor panel, i.e. joined with the floor panel in connection with the manufacture thereof.
  • horizontal plane or principal plane is meant a plane, which extends parallel to the outer part of the surface layer. Immediately juxtaposed upper parts of two adjacent joint edges of two joined floor panels together define a “vertical plane (V) " perpendicular to the horizontal plane. By “horizontally” is meant parallel tp the horizontal plane and by “vertically” parallel to the vertical plane
  • locking systems are meant co acting connecting means, which connect the floor panels vertically and/or horizontally.
  • mechanical locking system is meant that joining can take place without glue.
  • discontinuous surface layer and core is meant the surface layer and core of two elements connected to each other to form one panel or two panels connected to each other to form a floor and consequently the core and the surface layer of the elements and the panels respectively is discontinuous. A joint is detectable between the two element or panels at the discontinuity.
  • Printing and pressing technology have in recent years been developed further and very natural copies of stone, tiles and parquet strips have been introduced on the market. There are however a lot of designs and patterns which are not possible to produce and install with the present printing, pressing and mechanical locking technology.
  • a first overall objective of the present invention is to provide a flooring system and floor panels, preferably with mechanical locking systems, which could be installed in advanced patterns and where the pattern to a large extent is obtained by the size, shape and mechanical working of the panels and not only by printing and pressing technology.
  • a limited range of semi-finished boards could be machined into floor elements and combined to a wide range of new floor panels. This could be accomplished without changing the printing cylinders and press plates.
  • the object is to provide floor panels with mechanical locking system where one or several of the following advantages are obtained.
  • the floor panel should preferably be possible to assemble mechanically to a floor surface which generally only could be obtained with small individual wood, tile or stone pieces with different sizes and structures and with panels, which are not floating but glued or nailed to the sub floor
  • the floor panels should be easy to install in spite of the fact that the floor pattern could comprise a lot of small floor panels with different sizes and advanced shapes which differ from the traditional rectangular floor panels based on the same print and pressing plates.
  • a flooring system comprising a plurality of floor panels.
  • the floor panels comprise a discontinuous core having a core joint and a discontinuous surface layer having a surface joint.
  • the floor panels are mechanically connectable to each other along one pair of adjacent edges and comprising at least two floor elements which are connected to each other with glue and that the surface joint is adjacent to the core joint.
  • the floor elements are factory connected to a floor panel and delivered as floor panels preferably in a package to the installation place as parts of a pre installed floor.
  • a floor panel which is formed of several individual floor elements, offers a lot of advantages. Patterns could be created which are not possible to produce with printing or linear machining of the edges. Installation is easy since several floor elements could be installed at the same time.
  • An essential feature of the invention is that joint between the floor elements could be rather simple, cheep and strong since the floor elements are connected with glue in the factory where suitable equipment could be used. A lot of very compact preferably glue based tongue and groove connections could be used and the waste could be reduced considerably.
  • the floor is to a large extent pre-installed at the factory and the individual elements could be connected to each other in a very efficient way. A lot of time consuming and difficult installation work where the floor installer has to work close to the floor, could be moved to a controlled factory environment.
  • Figs la-4b illustrate prior art locking systems.
  • Figs 4c-5 illustrate a first embodiment of the invention
  • Figs 6a-10c illustrate further embodiments of the invention.
  • Figures Ia - Ic show known mechanical locking systems, which could be locked with angling and/or snapping. These locking systems have a tongue 10 and a grove 9 for vertical locking of adjacent edges parallel to the vertical plane V and a locking grove 12 and a locking element 8 for horizontal locking parallel with the horizontal plane H. The locking element could be located on a tongue 10 or a strip 6. These locking systems are very suitable to use in floor panels according to the invention.
  • Figures 2a-2c show mechanical locking systems, which could be locked by horizontal snapping.
  • the locking elements could be made in one piece with the core as in figure 2c or of a separate material, hereafter referred to as two piece snap, as in figure 2a and 2b. These snap systems have a low snapping resistance and a high locking strength and are therefore also very suitable to use in floor panels according to the invention.
  • Figure 3a - 3c show mechanical locking systems which could be locked by a vertical folding.
  • Such systems could have means for horizontal locking only, as in figure 3a, or they could have a small tongue 10 made in one piece, as in figure 3b.
  • Alternative the tongue 10 could be flexible as in figure 3c.
  • Such vertical folding with a tongue, which is displaceable horizontally, is very suitable to use in the floor panels according to the invention.
  • Such systems are referred to a flex tongue systems.
  • Fig. 4a-4b show traditional locking systems, which are locked vertically with a tongue 10 and a grove 9 and horizontally with glue 7.
  • Figure 4c show how a tongue and groove joint could be adjusted to be used in a factory connection of floor elements .
  • the tongue 10 has been made smaller since special glue with controlled equipment could be used.
  • the under lip 6 has been made slightly longer and extends beyond the upper lip 6' . This simplifies the application of glue and the under lip 6 could be formed such that it creates a vertical pre tension and keeps the floor element together until the glue cures .
  • Fig. 5 illustrates schematically a cross section of a floor panel 2 according to one embodiment of the invention, which comprise two separate floor elements 1, 1', which have been factory connected with a tongue and groove locking system.
  • the floor panel 2 has a surface layer 31 and a core 30, which are discontinuous, and edges, which in this preferred embodiment could be locked with angling.
  • the floor elements have a decorative groove 40, bevel or similar on one edge.
  • All these locking systems could be used in various combinations to connect floor panels according to the invention.
  • Mechanical locking systems could be adjusted to lock for example floor elements with a simple compact snap system, which only holds the panels together until the glue cures .
  • Preferred embodiments to connect floor elements are locking systems, which are only using glue, since the panels could easily be positioned correctly horizontally to each other in the factory and generally no horizontal connection is needed.
  • Floor elements could also be connected with tape on the rear side or glued to a underlay 16 which could be a foam, a cork layer, various types of plastic materials, wood based sheet materials or wood veneer or similar. Such connections are to be considered as a glue connection
  • Figure 6a shows two rectangular floor elements 1, which is connected with several similar floor elements to a floor panel 2.
  • the floor elements could have a surface of the same material, for example laminate, but they could also have a surface layers of different materials for example laminate-wood, plastic material-laminate, Cork - wood etc. More than two different materials could be combined.
  • the floor elements have decorative grooves 40 on two edges
  • Figure 6b show how floor panels 2 could be installed to a floor with combinations of angling, snapping and vertical folding.
  • Figure 6c shows a cross section along the line A — A in figure 6b.
  • the floor elements 1, 1' have two edges 4a, 4d, which could be connected mechanically with angling and two edges 4b, 4c which could be connected with a compact glued 7 tongue 10 and grove 9 joint.
  • the other two opposite edges of the floor panel are preferably provided with an angling locking system or a flex tongue system.
  • Figure 7a shows two floor elements 1, 1' with mirror inverted locking systems.
  • the panels are generally referred to as A and B panels. Both floor elements have a grove 9 on the same long edge but on different short edges . These two floor elements could be connected to floor panels 2, which are only of one type. This simplifies packaging and distribution.
  • Figure 7b shows the floor panels connected to a floor. These panels are preferably locked with angling or vertical folding.
  • Figures 8a -8c show how two floor elements 1, 1' of different sizes could be factory connected to a floor panel 2. They are just as easy to install as traditional floor panels but the design is more advanced because different structures, designs and decorative groves 40 could be combined and produced more efficient than with traditional technology.
  • Figures 8d - e shows an even more advanced installation pattern with floor panels comprising four different floor element with different sizes.
  • the invention makes it possible to produce floor panels with decorative groves between the edges of the panel and which meet each other in a T-shaped pattern 43a, 43b.
  • Figures 9a - 9c show that very advanced star shaped floors could be produced and installed.
  • Four floor elements Ia - Id could be connected to two different floor panels 2, 2' and connected to a star according to figure 9c.
  • Figure 9d-e show that very advanced floor panels 2 could be produced with floor elements of different shapes and sizes.
  • the floor panel could comprise more than forty floor elements . All floor elements could have decorative groves 40 or bevels.
  • the joint between the floor elements could be glued in such a way that they could prevent moisture from penetrating trough the joint.
  • Figures 10a - 10c show an embodiment of the invention involving a floor panel 2, which comprises a first Ia and a second Ib element shaped as a parallelogram, and a third quadratic panel Ic.
  • Figure 10b shows that the first Ia and the second elements Ib are mirror inverted and connected along adjacent edges and that the third quadratic element is connected to the edges of the first and second element, which are directed to -each other.
  • the floor panel is connected to essential identical floor panels 2' , 2'' with a combination of angling locking and/or flex tongue systems, as shown in figure 10c.
  • the outer parallel edges of the first and second element are provided with an angling locking system and the outer edges of the third element and its opposite outer edges of the first and second element are provided with a flex tongue system.
  • Figure 10a shows that if the element is coloured in different shades, and the floor panels are connected in a flooring installation, a three dimensional pattern is created.
  • the invention could be used to connect tile shaped panes installed on a wall or in furniture components .
