Definitions

  • the invention relates to a floor panel, to a method of construction a floor using such floor panels and to a method of producing such floor panels.
  • Prior art floor panels comprise a tongue and a groove, wherein, for assembling the floor panels, at least one of the floor panels needs to be lifted or tilted over a substantial angle.
  • US-6 769 218 describes a floor panel for constructing a floor, comprising a tongue extending along a first edge and comprising an upper and lower surface, a groove extending along a second edge, opposite the first edge and comprising an upper and lower surface, wherein the tongue comprises a protrusion at its upper surface, wherein the groove comprises an cavity in its upper surface, wherein the groove of a first panel is adapted to receive the tongue of a second panel.
  • the protrusion of the tongue of the second panel and the cavity of the groove in the first panel counteract and prevent horizontal separation in a direction transversal to a joint plane parallel to the first edge of the second panel and the second edge of the first panel.
  • the tongue with its protrusion can be inserted in groove and its cavity by horizontally snapping-in, the lower lip being bent so that the protrusion of the tongue can be inserted into the cavity in the groove.
  • the bending of the lower lip requires a certain flexibility of the material of the floor panel or at least its lower lip.
  • FIG. 769 218 Another floor panel described in US-6 769 218 has a joining system wherein the tongue, while a first panel is held in an upwardly angled position can be snapped into the groove of a second panel and then be tilted down by a pivoting motion about the upper joint edge.
  • this pivoting motion does not requires a flexible material, a pivoting motion about the upper joint edge requires a high level of precision, is therefore a time consuming activity, which especially for long floor panels can hardly be done by a single person without damage to the floor panels.
  • the aim of the invention is to provide a floor panel avoiding these problems. This aim is reached in that the upper and the lower surface of the groove extend at least partially in a downward direction from the edge to its distal end.
  • a tilted groove facilitates in assembling floor panels, in that the space opposite to the protrusion allows for less accurate positioning of floor panels in advance of assembling floor panels, while the assembled floor panels still result in a high quality constructed floor. This further facilitates assembly that can be carried out by just lifting and shifting the second panel in the first panel.
  • the downward direction of at least part of the groove makes it possible to assemble two panels even with a foot. This leads to easier and quicker constructing of floors, whereas also less damage to the floor panels will occur as no snapping is required for the assembling of two panels. This is of special interest in case of constructing floors by a single person.
  • a floor panel according to the invention by a single person doesn't require contact of the edges of their top main faces to insert a first floor panel into a second floor panel, which decreases the change of damaging the top layer and which makes inserting floor panels easier.
  • the space makes assembling floor panels less sensitive for little undesired fragments, especially fragments within the groove, such as fragments from the supporting floor.
  • other edges can be provided with one or more protrusions or cavities, for example the short opposing edges at the ends of the floor panel.
  • the part of the lower surface of the groove adjacent to the edge extends at least partially in the horizontal direction. This feature allows an easier insertion of the tongue into the groove and hence assembly of the panel.
  • the lower surface of the tongue extends substantially horizontally.
  • the upper surface of the tongue necessarily extends in a downward sloping direction to its distal end, required to offer space for the part of the upper surface after which the protrusion engages.
  • the feature of this embodiment provides the tongue with sufficient strength, in particular at its connection to the panel.
  • the lower surface of the tongue has preferably a rounded surface at its distal end. This allows easier insertion of the tongue in the groove and prevents sticking during assemblage.
  • the ratio between the depth of the groove and the greatest height of the groove is greater than two. This feature results in a longer thinner tongue so that only a relative minor tilt angle of the panel to be inserted relative to the panel already on the ground is required so that the insertion is further simplified.
  • edge surfaces of the panel part above and below the groove and the tongue extend in substantially the same vertical plane.
  • This feature implies that the length of the tongue is substantially equal to the depth of the groove, leading to large contact faces between both the under surfaces of the tongue and groove and upper surfaces of the tongue and groove, leading to a low local pressure between these parts.
  • Another advantage of this feature is that this features implies that there are no protrusions present in the edge surfaces of the panels above or beneath the tongue or the groove which may impair the insertion of the tongue into the groove.
  • At least one of the edge surfaces of the panel part above the tongue and above the groove extends substantially extends outward from the tongue in the upward direction.
  • At least one of the lower edges of the edge surfaces of the panel part is chamfered.
  • both upper edges are chamfered and the chamfered edges extend over the full length of the sides of the floor panel.
  • a second advantage of chamfered edges is that it provides the constructed floor with a more natural exposure, as if the floor is made from natural wood.
  • a preferred embodiment provides that at least one of the lower edges of the edge surfaces of the panel part is chamfered. Preferably both edges are chamfered to obtain the V-shaped groove.
  • the floor panel comprises cavities extending between the longitudinal edges extending parallel to the longitudinal edges. These cavities lead not only to a reduction of use of raw material and hence to a reduction of costs, but also to an improved thermal and acoustic insulation between the upper and lower surface of the panel.
  • the upper surface of the tongue is adapted to touch the upper surface of the groove, when the tongue is horizontally inserted in the groove, whereas space remains between the protrusion and the lower surface of the grove when the tongue is inserted in the groove while the first floor panel is tilted with a tilt angle of between 3° and 20°.
  • the advantage of this measure is that assembled floor panels are blocked in a direction transversal to a plane parallel to the first edge of the second panel and the second edge of the first panel.
  • a more rigid floor is provided, which has a better appearance and which will last longer, as less wear will occur due to the absence of relative movements between floor panels.
  • the floor panel is adapted so that during insertion of said tongue into said groove, the lower surface of said tongue and lower surface of said groove of the other floor panel touch, whereas space remains between edges of both floor panels above the upper surface of said tongue. With this remaining space a cumbersome pivoting motion about the upper joint edge is avoided. This further leads to a tolerance in vertical positioning a first floor panel relative to a second floor panel, as this measure leads to easier insertion with a smaller chance of damaging floor panels.
  • the cross section of the tongue perpendicular to the longitudinal direction of the edge is tapered.
  • the tongue has its largest thickness where it transfers into the floor panel and gets thinner away from the floor panel.
  • the tongue is thinner where it first enters the groove of another floor panel. Due to the tapered tongue, insertion of the tongue into the groove makes assembly easier.
  • a smaller thickness of the tongue away from the floor panel than the opening of the groove also facilitates assembly and avoids the risk of jamming during assembly. It also provides a tolerance in a direction perpendicular to the main surfaces of the panels when positioning the floor panels relative to each other.
  • the thickness of the base of the tongue at the edge provides a resistance against fracture of the tongue caused by a possible vertical movement of the first and the second panel relative to each other.
  • the tip of the tongue has a rounded surface at its distal end. This allows easier insertion of the tongue in the groove and prevents sticking during assemblage.
  • the protrusion and cavity extend over the full length of the corresponding sides of the floor panel.
  • Making use of a cavity and protrusion over the full length of their corresponding sides of the floor panels leads to a stronger fixation of floor panels, and thus a stronger constructed floor.
  • the floor panels can be made cheaper and assembling shortened floor panels, having various lengths, common practice when constructing a floor, is independent of the position of the cavity within the groove and the protrusion on the tongue, as they extend over the full length of the sides of the floor panel. Cheaper production is a result of the possibility of making the cavity or protrusion in a single process step, which doesn't hold in case of several protrusions and cavities in each floor panel, which should have corresponding positions during assembling of floor panels.
  • the floor panel according to the invention is made from a composite comprising wood fibres and a polymer.
  • the polymer in the floor panel of the invention can be any polyolefin or polyvinylchloride (PVC).
  • the floor panels of the present invention generally are a replacement for wooden floor panels.
  • Composites comprising wood fibres and a polymer strongly resemble wood, but are durable and have a much higher resistance against indentation by stiletto heels in particular when the composite is a composite of wood fibres and PVC.
  • the Young modulus of a wood fibre/PVC is generally more than 4 GPa. This high modulus prevents any snapping during the insertion of the tongue into the groove thus avoiding any risk of breaking out the lower lip of the cavity.
  • Another advantage of a wood fibre reinforced polymer over wood is its high dimensional stability with changes in the relative humidity.
  • the floor panels of the invention are preferably be made via extrusion, e.g. of a wood fibre/PVC mixture.
  • the advantage of making the floor panels via extrusion is that the groove can comprise a relatively deep laying cavity. Cavities that are deep laying, i.e. far from the edges of the lips of the groove are difficult, if at all, to make via milling.
  • a preferred embodiment provides a method for producing a floor panel comprising a panel part adapted to cover a floor with its main plane substantially parallel to the floor to be covered, a tongue extending along a first edge of the panel part and comprising an upper and lower surface and a groove extending along a second edge of the panel part, opposite the first edge and comprising an upper and lower surface, the method comprising the steps of mixing wood fibres or flour and pick, extruding the mixture thus obtained to produce the floor panel and cutting the extrusion product into lengths.
  • the method also comprises the feature that the floor panels are brushed, to obtain an appearance similar to that of wood.
  • the invention also relates to a method for assembling floor panels according to the invention, comprising the steps of placing a first floor panel on a supporting floor, placing a second floor panel on the supporting floor with its tongue directed to the groove of the first floor panel, moving the second floor panel towards the first floor panel to insert the tongue of the second panel into the groove of the first panel until the protrusion touches the upper surface of the groove and simultaneously upward pivoting and moving the first floor panel towards the second floor panel during which the upper surface of the tongue of the second floor panel supports the upper surface of the groove of the first floor panel or simultaneous upward pivoting and moving the second floor panel during which the lower surface of the groove of the first panel supports the lower surface of the tongue.

  • Figure 3 view similar to that of figure 2 during a further step in the process of joining two panels.
  • Figure 4 view similar to that of figure 3 in an alternative way of mounting.
  • Figure 1 depicts two floor panels Ia, Ib respectively, which have been joined together on a support floor 2.
  • Both floor panels Ia and Ib respectively comprise a panel part 3 with an upper face 4.

  • a tongue 6 is provided at said first edge 5.
  • the tongue extends over the full length of the floor panel Ia.
  • the panel part 3 of the second floor panel Ib comprises a second edge 7 with a groove 8 provide therein.
  • the groove 8 extends over the full length of the wall panel Ib.
  • the first floor panel Ia comprises also a second edge 7 with a groove provided therein, although it is not depicted in the drawing.
  • the second floor panel Ib also comprises a first edge 5 with a tongue 6.
  • the groove 8 has a component in a downward direction from the edge 7 to its distal end. This counts for the upper surface 9 of the groove 8 and for the lower surface 10 of the groove 8. At its distal end the groove 8 comprises a cavity 11 extending also over the full length of the panel Ib located above the groove 8. The upper surface 9 of the groove extends until the cavity 11.
  • the lower surface 10 of the groove 8 comprises a first part 8a extending substantially horizontally adjacent to the edge 7 and a second part 8b , extending with a component in a downward direction.
  • the tongue 6 comprises a lower surface 12 extending substantially horizontally and an upper surface 13 extending in a downward direction from the edge 5 to the distal end of the tongue. Adjacent to the upper surface, a protrusion 14 is connected to the tongue 6. The surface of the protrusion 14 at its side away from the edge 5 and at its lower side is curved.
  • the panels Ia, Ib comprise cavities 16 extending in the longitudinal direction of the panels Ia, Ib.
  • the features of the invention allow the panels Ia and Ib to be joined from a substantial horizontal direction. Put it otherwise, the panel Ia can be joined to panel Ib by simply shifting towards panel Ib already located in its correct position. Only a minor tilt of less than 3 ° of the panel Ia is required to obtain locking. Figure 3 shows clearly how this is achieved.
  • Panel Ia is located on the same support floor 2 as onto which the panel Ib is already present. Initially the panel Ia is located on the same floor and it is shifted substantially perpendicular to its longitudinal direction to the panel Ia, until both panels contact each other. As depicted in figure 2, the tongue of the panel 6 of the panel Ia will then already been inserted into the groove 8 of the panel Ib and the upper surface of the protrusion 14 will contact the upper surface 9 of the groove 8. Further linear movement is precluded. However a further insertion can be obtained by a small tilt of the panel Ia, as is depicted in figure 3. A tilt angle of about 3° is sufficient to allow a full insertion. A single person can easily achieve such a small tilt, even if the panels have a substantial length.
  • the small tilt makes the protrusion 14 free from the upper surface 9 of the groove 8 so that it can be inserted further.
  • the tilt requires further space at the lower part of the groove but this is provided by the downward direction of the second part 8b of lower surface of the groove.
  • Figure 4 illustrates that the way of joining two panels can also be executed the other way around; joining the panel Ib to panel Ia already present on the supporting floor.
  • this floor can be produced by extrusion of a mixture of pvc or another suitable plastic and wood flour, ore another suitable filler. Extrusion makes the provision of the through going cavities 16 particularly easy just as the tongue 6 and groove 8.
  • this panel refers to the application of this panel as the floor panel; it is by no way excluded that the panel can be used for other purposes, such as the cladding of walls. In particular its composition makes it very durable, so that these panels may be used for cladding of outside walls. Also then the attractive appearance similar to weathered panels is advantageous, as it looks like the weatherboard cladding common in the south of the UK.
