Definitions

  • the invention generally relates to the field of flooring systems and laminated floor panels, which could be installed in advance 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 floor panels described in WO 03/089736 . More precisely it refers to a flooring system comprising a package of a plurality of floor panels and a method of installing a flooring.
  • 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.
  • a locking system integrated with the floor panel i.e, mounted at the factory
  • 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 subfloor.
  • Laminate flooring usually comprise rectangular floor panels with a core of a 6-12 mm fibreboard, a 0.2-0.8 mm thick upper decorative surface layer of laminate and a 0.1-0.6 nm 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.
  • Laminate flooring look like wood, but are more durable and less expensive than wood flooring.
  • 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 to 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 that the surface layer and core of two elements are connected to each other to form one panel, or two panels connected to each other to form a floor. 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.
  • a first overall objective of the present invention is to provided a flooring system comprising floor panels 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 the elements and not only by printing and pressing technology.
  • the object is to provide a flooring system comprising panels with mechanical locking system where one or several of the following advantages are obtained.
  • Another object is to provide a method of installing such flooring.
  • 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 or non parallel edges 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 panels.
  • a flooring system comprising a plurality of floor panels with a core and a discontinuous surface layer.
  • the floor panels are mechanically connectable to each other along one pair of adjacent edges and each floor panel comprises at least two floor elements whereof at least one of the floor elements is non rectangular.
  • the floor elements are factory connected to a floor panel and delivered as floor panels in a package to the installation place as parts of a pre installed floor.
  • the connection between floor elements should be such that several floor elements are kept in a pre determined position in relation to each other during installation. This connection could be such that floor elements are permanently connected with for instance glue or mechanical locking system, which keeps the floor elements in a correct position during installation.
  • 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. The joint between the floor elements could be rather simple and cheep but still strong and reliable since the floor elements are connected in the factory where suitable equipment could be used. 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.
  • Figures 1a - 1c show known mechanical locking systems, which could be locked with angling and/or snapping. These locking systems have a tongue 10 and a groove 9 for vertical locking of adjacent edges parallel to the vertical plane V and a locking groove 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.
  • 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 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 , hereafter referred to as vertical hook systems or they could have a small tongue 10 made in one piece, as in figure 3b , hereafter referred to as vertical tongue systems.
  • 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 groove 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, which comprises 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 elements 1, 1' or two or several adjacent edges of floor panels.
  • Mechanical locking systems could be adjusted to lock for example floor elements vrith a simple snapping which only holds the panels together until the glue cures.
  • Preferred embodiments to lock floor elements are locking systems using glue, since the panels could easily be positioned correctly horizontally to each other in the factory.
  • Floor elements could also be connected with tape on the rear side or be 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.
  • Figure 6a shows two non rectangular floor elements 1, 1', which are connected to a floor element 2 as shown in figures 6a-6b .
  • the floor elements could have a surface of the same material, for example laminate, but they could also have 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 three edges. An advanced floor panel with decorative grooves, which in this embodiment meet each other at an angle different from 90 degree, could be produced with linear machining.
  • Figure 6d show how floor panels 2 could be installed in the order of A-H with combinations of angling, snapping and vertical folding. Rather simple locking systems could be used since the irregular shape of the panels could be used to prevent displacement along the length direction of the panels.
  • Figure 6e shows a floor with an advanced pattern according to the invention.
  • a floor could be installed just as easy as traditional rectangular floor panels. It is obvious that six, eight or more floor elements could be connected to a floor panel. Start and end pieces with straight edges could be supplied.
  • Figure 7a shows a floor element 1 which is used to form a floor panel 2 similar to the floor panel in figure 6 .
  • the floor panel 2 has nine pairs (4a-4i and 5a -5i) of edges.
  • the floor panel 2 comprises six pairs (4c-d 4d-e, 4g-h, 5b-c, 5e-f and 5f-g) of adjacent edges, which are inclined with an angle (A) of more than 90 degrees.
  • the panels could be locked in several ways.
  • the parallel edges (4b-5b, 4d-5d, 4f-5f, and 4h-5h could for example have a one or a two piece snap system and the other edges could have a traditional tongue and groove system. Alternatively all edges could be locked with horizontal snapping.
  • Two pairs of adjacent edges (4b-5b and 4f-5f) could have an angling system and two pairs (4d-5d and 4h-5h) could have a flex tongue system. All other edges could have a vertical hook system or a vertical tongue system or a flex tongue system or any other system that allows vertical folding.
  • the floor panel comprises two protrusions (P1, P2) with straight edges, which are positioned along a straight line L. Such protrusions will block mutual displacement of connected panels.
  • the straight edges 4b, 4f of these protrusions could have a mechanical locking system, which could be locked with angling to opposite parallel edges 5b, 5f of a similar panel. The other edges could be locked with vertical folding.
  • Figures 7c-7f show different embodiments according to the same principles.
  • nine pairs of adjacent edges (4a-4i and 5a-5i) could be connected to each other and two pairs of adjacent edges (4c-5b and 4g-5f) could for example be connected with angling.
  • eleven pairs of adjacent edges (4a-4k and 5a-5k) could be connected to each other and there are three protrusions P1, P2, P3 with three pairs of edges (4d-5a, 4g-5d and 4j-5g) which could be connected with for example angling and the other edges could be connected with for example vertical folding.
  • edges preferably could have a length of 80 - 200 mm
  • FIGs 8a-8e and 9a-9d show different embodiments.
  • the floor panels according to figure 8d are installed offset to each other while the floor panels in figure 9d are installed side by side in parallel rows.
  • the invention could be used to connect tile shaped panes installed on a wall or in furniture components.
