Definitions

  • the present invention relates to, on the one hand, a panel (profiled strip) with improved connecting means (coupling means).
  • the panel may be both a floor and a wall panel.
  • the present invention relates to a method for forming such a panel (profiled strip).
  • connection can absorb only small upward forces caused by unevenness of the floor.
  • the force with which the floorboards are joined is also the force with which they can come apart (cf. EP 0085196 and EP 0562402). Due to the fact that the floorboards are pushed downwards by a simple push of the thumb, this relatively small force is the same as the one with which the floorboards can come apart.
  • several versions are known which use inserts made from a different material than the floorboard itself (cf. EP 1 650 375 and EP 1 415 056 ).
  • the object of the invention is achieved by providing a profiled strip comprising a visible side, a first end side provided with first male and first female connecting means, and a second end side which is situated opposite the first end side and is provided with second male and second female connecting means, in which the connecting means are suitable to join the end sides of adjoining profiled strips with one another by engagement of the male and the female connecting means, in which the profiled strip furthermore comprises first vertical locking means which are provided to produce a vertical lock between adjoining profiled strips, and in which the first vertical locking means are made from the same material as the profiled strip and comprise a pliable projection which forms part of the first or second male connecting means.
  • a first locking means provides a flexible lock, as it were.
  • the first locking means are made from the same material, such profiled strips have the significant advantage that they can be produced quickly and in a very simple manner. This is in contrast with the known profiled strips, where the locking means are configured as a so-called insert which is fitted to a semi-finished product which is mainly composed of wood or a derivative thereof, for example MDF, HDF or chipboard (see for example WO 2007/141605).
  • the vertical lock is understood to mean a lock extending in a vertical direction substantially at right angles to the surface of the visible side.
  • the first vertical locking means furthermore comprise a recess which forms part of the first or second female connecting means
  • the pliable projection is configured to carry out a bending movement during the joining of the adjoining profiled strips in the direction of the adjoining end side by moving in the recess in order then to at least partly bend back into its original position when the first or second male connecting means engage in the first or second female connecting means.
  • the profiled strip according to the invention is made in a single part.
  • the profiled strip according to the invention, and therefore also the pliable projection, are preferably made from plastic, more particularly from PVC, PP and PE. This offers the advantage that such profiled strips can be used in order to create a floor or wall covering which is impermeable to water.
  • the profiled strip comprises a decorative top layer.
  • Said top layer is preferably fixedly attached to the visible side of the profiled strip.
  • the profiled strip furthermore comprises second vertical locking means which are configured to provide a second vertical lock between adjoining profiled strips.
  • the second vertical locking means are formed by providing the one end side with an oblique side or a recess, preferably a V-shaped recess, and providing the other side with a similar oblique side or a projection fitting in the recess, preferably a V-shaped projection.
  • a (vertical) lock is formed between adjoining profiled strips which is rather inflexible.
  • a V-shaped projection for the second lock use can be made of the possible compressibility of the material.
  • oblique sides which, in certain embodiments in which the pliable projection is provided on the first male connecting means, make the second vertical lock possible, are illustrated in Figs. 1 to 6, and adjoin the side of the profiled strip which is situated opposite the visible sides.
  • the oblique sides are provided in such a manner that the oblique side of the one profile will slide over the oblique side of the adjoining profile when joining adjoining profiled strips.
  • the second vertical locking means are formed by the V-shaped projection and the V-shaped recess interacting therewith.
  • first female connecting means I'D
  • second male (IB) connecting means see, inter alia, Fig. 2
  • first female connecting means are configured as a cavity
  • male connecting means are configured as a projection which engages in said cavity.
  • Another subject of the present invention is a method for forming a profiled strip comprising: a first end side provided with first male and first female connecting means, a second end side situated opposite the first end side and provided with second male and second female connecting means, and first vertical locking means which are configured to produce a vertical lock between adjoining profiled strips, in which said locking means comprise a pliable projection, the method comprising the following steps:
  • said profiled strip furthermore comprises second vertical locking means which are configured to produce a second vertical lock between adjoining profiled strips, in which said second vertical locking means are provided during said machining operation.
  • the method according to the invention is in particular designed to form a profiled strip as described in the attached claims.
  • the recess - in which the pliable projection fits when the two profiled strips are joined together - will also be formed during the machining operation.
  • the required recesses, projections and/or bevelled edges are also provided via a machining operation in those cases where a double vertical lock is required.
  • longitudinal sides also have to be provided with connecting means in order to join profiled strips to one another along their longitudinal sides.
  • the present invention furthermore relates to a floor or wall covering made from a number of the above-described profiled strips.

  • Figs. 7 to 9 show a number of alternative (third) embodiments
  • Figs. 10 and 11 show how the profiles illustrated in Fig. 8 are positioned with respect to one another, before and during fitting thereof.

  • the projecting part l 'C of the connecting means ⁇ 20 of floorboard is in addition provided with a movable part 7 which forms an integral part of the connecting means 1 '20 which in turn forms an integral part of the floorboard 1 '.
  • the movable part 1 '7 has a double function. On the one hand, it will ensure the ends of the decorative sides 12 and 2 cannot come into contact with one another until the very last moment during the joining process when the floorboard 1 ' is being joined to floorboard 1 and the associated downward movement. In addition, the movable part 7 will provide a first lock of floorboard 1 with floorboard ⁇ after it has engaged into the recess 111 which forms part of the notch 1 A of the connecting means 120.
  • the present design also provides an additional lock as, depending on the base material of the floorboards to be joined, the dimensions of the movable part 1 '7 have to be modifiable.
  • the present design provides the possibility to give the movable part 1 '7 a different design than for a soft, more flexible material, and this without any significant effect on the force K which is necessary to join the floorboards together and the force F which could separate the floorboards from one another or could move point 12 with respect to point 2 after fitting.
  • the additional lock of the floorboards 1 and 1 ' is achieved in the following way.
  • floorboard 1 ' has been moved vertically H with respect to floorboard 1 across distance El
  • the oblique side 4 of the notch I 'D of the connecting means ⁇ 20 comes into contact with the oblique side 14 of the projecting part IB of the connecting means 120.
  • the movable part 7 also still has its original shape and is not yet subjected to bending.
  • the movable part 1 '7 acts as a spacer between the end of the decorative sides 12 and 1 '2.
  • the end 3 of the movable part 1 '7 comes into contact with the side 17 which forms part of floorboard 1.
  • the additional lock is achieved during the oblique displacement of floorboard 1 with respect to floorboard 1 ' in the direction Z across the distance E2 along the oblique sides 14 and 4.
  • This is due to the fact that the projecting part IB of the connecting means 120 of the floorboard 1 is provided with an oblique side 15.
  • the notch I'D of the connecting means ⁇ 20 is likewise provided with an oblique side ⁇ 5.
  • the oblique side 5 will move along the oblique side 15.
  • the projecting part 30 underneath the oblique side 5 of the floorboard ⁇ is now below part 130 of floorboard 1 and will provide additional resistance to an upward force F caused by certain uneven structures on the floor FL.
  • the movable part ⁇ 7 will also move X in the recess ⁇ 6 of the projecting part l'C in order to make a displacement in the oblique direction Z of floorboard 1 ' with respect to floorboard 1 possible.
  • the ends of the decorative sides 12 and 1 '2 will now finally start to move towards one another.
  • the bottom side 1 '10 of the projecting part 1 'C will come into contact with the top side 110 of the notch 1 A.
  • the movable part 7 will also move in the recess 111 which forms part of the notch 1A.
  • the movable part ⁇ 7 will assume its original position again and the recess 1 '6 will also assume its original shape. Once this has happened, a lock has been achieved due to the contact of the top side 9 of the movable part 1 '7 with the side 19 of floorboard 1.
  • the force F used to release the joint will have to be significantly higher than the force K which was required to achieve the joint, which are basic characteristics in the industry for a simple, high-quality joint between floorboards.
  • the additional lock at the location of the oblique side 15 and 1 '5 makes it possible to join floorboards of different types which are made from various materials and have different mechanical properties to one another without requiring additional investment and without having to sacrifice the joining force, by means of a simple change in the dimensions of the movable part 7 by a simple displacement of a milling cutter.

  • This metering screw is , also provided with a smaller funnel through which other additives can be added, such as blowing agents, colour pigments and, optionally, stabilizers or other additives which may be required to ensure an optimum formulation.
  • the metering screw provides a continuous stream of base material to the heated cylinder which is provided with one or more heated screws in an extruder.
  • the main parameter of the extruder is the L/D ratio or, more accurately, the ratio of the length of the cylinder to the diameter of the cylinder. This ratio is of great and defining importance in order to be able to process certain materials and to produce a PVC plate of the correct hardness.

  • the screw geometry is essential, the correct distance between the flanges of the screw and the structure of the mixing zone on the screw is crucial for satisfactory plastification.
  • the degassing zone in the cylinder of the extruder ensures that the gasses which have accumulated during the heating process are removed and the position thereof is also crucial to achieving a good result.
  • the material While the screws transport the material to the die, the material has to be heated, homogenized and plastified/plasticized. Each material has a different plasticizing process and therefore the composition of the material is so important to the selected L/D ratio.
