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).
  • a significant drawback of the horizontal movement, more widely known as the snap-movement, of the floorboards with respect to one another is the fact that, on the one hand, an accessory and a hammer are required and that the hammering force, which is applied in order to join the floorboards together, may cause damage to the decorative top layer. The same may occur if the accessory is not handled correctly which serves to prevent damage to the protruding tongue on the other end of the floorboard to be connected.
  • the force used to hammer the correctly placed accessory has to be regulated in order to achieve such a connection.
  • 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 ).
  • Figure 37 of US 2010/031594 A1 shows a profiled strip according to the preamble of claim 1.
  • DE 10 2004 001363 A1 also discloses a profiled strip.
  • the object of the invention is achieved by providing a profiled strip according to claim 1.
  • a profiled strip according to claim 1. Such a first locking means provides a flexible lock, as it were. Due to the fact that 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 profiled strip according to the invention and therefore also the pliable projection, are preferably made 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, and providing the other side with a similar oblique side. In this way, a (vertical) lock is formed between adjoining profiled strips which is rather inflexible.
  • oblique sides which, in certain embodiments according to the present invention 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 a V-shaped projection and a V-shaped recess interacting therewith.
  • first female connecting means I'D
  • second male (1B) connecting means see, inter alia, Fig. 2
  • horizontal lock in accordance with a horizontal direction at right angles to the end sides
  • the first female connecting means are configured as a cavity
  • the 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 in a single part according to independent method claim 4.
  • 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 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.
  • the above elements 1 and 1' to be joined together are floorboards substantially composed of polymer or polyolefines.
  • the materials which can be used for the floorboards 1 and 1' depend on the mechanical properties, more particularly the flexibility of the pliable projection 1'7.
  • the floorboards have a decorative finish on the top side 11 and 1'1, and have a critical point 12 and 1'2 at the end of each decorative side which may cause damage when the floorboards are joined together.
  • Both floorboards 1 and 1' have connecting means 120 and 1'20, respectively, consisting of a notch 1A and I'D, respectively, and a projecting part 1B and 1'C, respectively.
  • the projecting part 1'C of the connecting means 1'20 of floorboard 1' is in addition provided with a pliable projection 1'7 which forms an integral part of the connecting means 1'20 which in turn forms an integral part of the floorboard 1'.
  • the pliable projection 1'7 has a double function. On the one hand, it will ensure the ends of the decorative sides 12 and 1'2 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 pliable projection 1'7 will provide a first lock of floorboard 1 with floorboard 1' after it has engaged into the recess 111 which forms part of the notch 1A 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 pliable projection 1'7 have to be modifiable.
  • the present design provides the possibility to give the pliable projection 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 1'2 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 E1
  • the oblique side 1'4 of the notch I'D of the connecting means 1'20 comes into contact with the oblique side 14 of the projecting part 1B of the connecting means 120.
  • the pliable projection 1'7 also still has its original shape and is not yet subjected to bending.
  • the pliable projection 1'7 acts as a spacer between the end of the decorative sides 12 and 1'2.
  • the end 1'3 of the pliable projection 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 1'4.
  • This is due to the fact that the projecting part 1B of the connecting means 120 of the floorboard 1 is provided with an oblique side 15.
  • the notch I'D of the connecting means 1'20 is likewise provided with an oblique side 1'5.
  • the oblique side 1'5 will move along the oblique side 15.
  • the projecting part 1'30 underneath the oblique side 1'5 of the floorboard 1' 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 pliable projection 1'7 will also move X in the recess 1'6 of the projecting part 1'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 1A.
  • the pliable projection 1'7 will also move in the recess 111 which forms part of the notch 1A.
  • the pliable projection 1'7 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 1'9 of the pliable projection 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 pliable projection 1'7 by a simple displacement of a milling cutter.
  • a profiled strip (floorboard) according to the present invention formed by means of a method which at least comprises the following steps:
  • said profiled strip furthermore comprises second vertical locking means which are configured to provide a second vertical lock between adjoining profiled strips, said second vertical locking means are provided during said machining operation.
  • the production process starts with transporting the various materials (in powder and in granular form), by means of a screw conveyor, to a premixer where a first cold mixing is carried out.
  • the premixer will in turn transport the mixed material to a funnel which is provided with a metering screw at the bottom.
  • 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 cylinder and screws of the extruder are given special treatment and are hardened against corrosion and mechanical wear.
  • the cylinder and screws are composed of different zones, each of which can be controlled and adjusted individually in order thus to be able to heat or cool each zone separately.
  • the quality of the product is greatly dependent on the production parameters which are used. Relevant production parameters are the melting point, cylinder temperature, die temperature, mass pressure and mass temperature.
  • 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.
  • a die At the end of the extruder, a die is provided which ensures that the material flowing out of the intruder will already have a certain flat shape and ensures that this process is carried out in optimum fashion.
  • the thickness of the plate can be modified by adjusting the cooled lips at the front of the die to the correct thickness.
  • the parallelism of the plate across the entire width is, on the one hand, controlled by a vertically displaceable control lath which is situated in the die and by adjustment of the calender, as the extruded material, upon leaving the die, will pass through a calender.
  • the calender is provided with three cylinders (the hollow cylinders are provided with water), each of which can be controlled individually in order to be able to set the correct temperature for each cylinder.
  • the parameters which are essential in this process are the speed, temperature, opening between the cylinders, diameter of the cylinder, treatment of the surface of the cylinder.
  • the plate is cooled down and calibrated.
  • the plate is passed between 2 cylinders and thus follows the rotational speed of the central cylinder in order to thus be transferred to the 3rd cylinder which then transfers the plate to the roller track.
  • the adjusted diameter of the cylinder or by using several cylinders, it is possible to cool down the plate sufficiently, so that the plate becomes sufficiently rigid in order to then be transported further on the roller track. If the plate has not cooled down sufficiently, it can be cooled still further in a water tank.
  • the quality and treatment of the cylinder ensures that the plate acquires the desired surface quality.
  • the following line is provided with a long roller track (if desired with water tank), draw bench and sawing machine.
  • the length of the roller track and any associated water tank is defined in such a manner that the plates are completely cooled down when they reach the draw bench.
  • the speed of the draw bench is adapted to the extrusion speed and the following speed of the saw. After sawing, the plates are placed on a pallet and, after a predetermined conditioning period, they are ready for processing.
  • a third possible variant consists of a combination of the abovementioned processes by using a die but also using more than one extruder.
  • This is referred to as a coextrusion process and is similar to the 1 st abovementioned process, except that several extruders are used in order to be able to optionally change the material composition in the coextrusion layer or the base layer.
  • it is also possible, if desired, to use an air or water cooling mechanism of the plate instead of a calender after the material has flowed out of the die in plate shape.
  • the following steps in the production process are similar to those in the above descriptions, i.e. to the draw bench and saw bench via a roller track.
  • this plate may, if necessary, furthermore be provided with a decorative top layer.
  • this decorative top layer can be joined to the extruded or calendered plate using heat, this top layer can be provided at the location of the calender if the temperature of the extruded or calendered plate is still sufficiently high or the plate can be heated after leaving the extrusion line in order to be able to attach the decorative top layer.
  • This decorative top layer can also be applied by using an adhesive bonding technique instead of using heat.
  • the produced plates are sawn into smaller formats and provided with the above-described connecting and locking means at the (head) ends of the sawn plates via a machining operation, for example by means of a milling device.
  • the longitudinal sides are also provided with connecting means (coupling means) using the known techniques.
