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 slot, wherein, for assembling the floor panels, at least one of the floor panels needs to be lifted
  • 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.
  • US6769218 describes a floor panel constructing a floor, comprising:
  • Another floor panel described in US6769218 has a joint system where 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 angled 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.
  • 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 tips 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.
  • 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.
  • 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.
  • a material which can be extrudes and which is nevertheless sufficiently strong hard and durable, is a composite from wood fibres or wood flour and pvc.
  • a preferred embodiment provides a floor panel, which is composed of a composite from wood fibres and pvc. It is noted that such a material has, after some post processing, like brushing, a pleasant appearance not unlike the appearance of weathered wooden panels, so that there is no need to provide a upper layer on the panel as is common in laminated floor panels.
  • 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.
  • a floor panel wherein 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 degrees.
  • 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 characterized in 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 floor panel comprises a tongue of which the cross section 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 during assembling.
  • 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 cross section of the tongue groove perpendicular to the longitudinal direction of the edge is tapered. This leads to a more rigid fixation of floor panels, especially in a direction perpendicular to their main faces, if the shape of the tapered groove corresponds with the tapered tongue of another floor panel
  • the tip of the tongue has a rounded surface at its distal end.
  • the protrusion and cavity, respectively of the tongue and the groove 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 fibers and a polymer.
  • the polymer in the floor panel of the invention can be any polyolefin or polyvinylchloride (PVC).
  • PVC polyvinylchloride
  • the floor panels of the present invention generally are a replacement for wooden floor panels.
  • Composites comprising compising wood fibers and a polymer strongly resemble wood, but are durable and have a much higher resistance against indentation by stilleto heels in particular when the composite is a composite of wood fibers and PVC.
  • the Young modulus of a wood fiber/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 fiber 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 fiber/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.c. far from the edges of the lips of the groove are difficult if at all to make via milling.
  • the advantage of a deep laying cavity, e.g. in a groove with a distance between its edges and its bottom end which is more than twice the size of its vertical opening, is that this requires only a tilting angle between about 3 and 5 degrees to insert the tongue into the groove.
  • 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.
  • Both floor panels 1a, 1b respectively comprise a panel part 3 with an upper face 4.
  • the panel part 3 of the first floor panel 1a comprises a first side wall 5.
  • a tongue 6 is provided at said first side wall 5.
  • the tongue extends over the full length of the floor panel 1a.
  • the panel part 3 of the second floor panel 1b comprises a second side wall 7 with a groove 8 provide therein.
  • the groove 8 extends over the full length of the wall panel 1b.
  • the first floor panel 1a comprises also a second side wall 7 with a groove provided therein, although it is not depicted in the drawing.
  • the second floor panel 1b also comprises a first side wall 5 with a tongue 6.
  • the groove 8 extends substantially in a downward direction from the side wall 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 1b 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 side wall 7 and a second part 8b , extending 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 side wall 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 side wall 5 and at its lower side is curved.
  • the panels 1a, 1b comprise cavities 16 extending in the longitudinal direction of the panels 1a, 1b.
  • the features of the invention allow the panels 1a, 1b to be joined from a substantial horizontal direction. Put it otherwise the panel 1a can be joined to panel 1b by simply shifting towards panel 1b already located in its correct position. Only a minor tilt of less than 3 degrees of the panel 1a is required to obtain locking. Figure 3 shows clearly how this is achieved.
  • Panel 1a is located on the same support floor 2 as onto which the panel 1b is already present. Initially the panel 1a is located on the same floor and it is shifted substantially perpendicular to its longitudinal direction to the panel 1a, until both panels contact each other. As depicted in figure 2 , the tongue of the panel 6 of the panel 1a will then already been inserted into the groove 8 of the panel 1b 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 1a, as is depicted in figure 3 . A single person, even if the panels have a substantial length, can easily achieve such a small tilt.
  • 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 rear 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 1a to panel 1b already present on the supporting floor.
  • this floor can be produced by extrusion of a mixture of pvc ore 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 weather board cladding common in the south of the UK.
