Abstract

A floor covering (10) composed of panels (12, 14, 112) comprising a core (24) of a plastic material and at least one cover layer (28, 30) covering the top of the core (24), and which at their associated side edges (16, 18) with complementary and positively interlocking locking profiles (20, 22, 120) are provided, characterized in that to form a joint between two connected panels (12, 14, 112) at least one of these panels the top of its side edge (18) is provided with a cutout (60; 160) over the width of which the cover layer (28, 30) is completely removed so that the bottom (62; 162) of the cutout (60; Core material is formed.

Description

  • The present invention relates to a floor covering which is composed of panels according to the preamble of claim 1.
  • Such floor coverings exist in a wide variety of embodiments. For example, panels with a core of wood-based materials such as MDF or HDF are widespread. On the core is usually a decorative layer, which is modeled, for example, a wooden look. The decorative layer in turn is covered by a transparent wear layer which is resistant to wear and can consist of a plastic or a resin. The underside of the panel is formed by a Gegenzugschicht to prevent deformation of the panel body.
  • In addition, for some time floor panels with a core of a plastic material such as PU (polyurethane) or PVC (polyvinyl chloride) exist. Compared with panels made of wood-based materials, these offer the advantage of a higher elasticity and improved performance properties, for example with regard to impact sound insulation. Also, these plastic panels usually have on their upper side at least one cover layer, which covers the top of the core. The connection of two panels is usually done by locking profiles on the side edges, which are each complementary to each other and positively engage with each other, in the manner of a tongue and groove connection. In this way, adjacent panels can be held together so that their tops close together tightly and without gaps.
  • From the market lately increasingly an embodiment of panels is desired, which simulates a tile look, in which the panels are optically separated by joints. For this purpose, a joint optics was previously printed on the top of the panels and formed by pressing technique as a recess, which is also haptically perceived as a joint. However, this does not always lead to a satisfactory result. Above all, wider and deeper joints can not be realistically reproduced using the techniques described above. What is desired above all is a floor covering which mimics floor tiles separated by joints with the aid of the above-mentioned panels with a plastic core.
  • Object of the present invention is therefore to provide a floor covering of panels with a plastic core, which imitates a tile look with joints realistic, as it is possible with the previously known techniques. Another object of the invention is to create the replica of the joint optics in the most efficient way possible without additional operations such as printing or pressing.
  • These objects are achieved by a floor covering with the features of claim 1.
  • According to the invention, one side edge of the panel, which adjoins the adjacent panel, is provided on its upper side with a cutout which extends along the edge. Over the width of the cutout, the visible covering layer of the panel is completely removed, to such an extent that the ground of the cutout is formed by the core material, that is to say by the plastic which forms the core. Between two connected panels thus forms a groove, which represents the joint.
  • This groove can be made considerably deeper by milling than by the known pressing techniques. In addition, the contrast between the core material at the bottom of the cutout and the adjacent cover layer which replicates the tile surface, can contribute to the realistic impression. This cover layer may in particular be a decorative layer, which in turn is laminated by a durable transparent wear layer, as mentioned above. The shape of the cutout can reproduce the haptic impression of the joint as desired.
  • Incidentally, the joint according to the invention can be formed by a joint cutter on the side edge, without the locking profile being weakened. It is possible in particular the formation of locking profile and cutout for the joint in a single operation, for example by a combination tool.
  • According to a preferred embodiment of the present invention, the reason of the cutout forms a horizontal bottom of the joint.
  • Further preferably, the joint has a substantially rectangular cross-section with approximately vertical side walls.
  • According to a further preferred embodiment, the upper edges of the side walls of the joint are provided with bevels. These form chamfers, which avoid a sharp-edged transition between the top of the panel and the joint.
  • According to another preferred embodiment, the bottom of the joint is sealed by a seal coating. This can be water repellent, so that penetration of water into the core of the panel is prevented. Furthermore, can the seal coating be dirt-repellent. If the seal is transparent, the bottom of the joint remains visible. If desired, the seal coating can be colored to represent a contrast to the decorative layer.
  • In a method of manufacturing a panel of such a floor covering, the locking profile provided on the side edge as well as the cut-out thereon are formed by milling, and the locking profile and the cut-out are made simultaneously in a single operation.
  • In this method, the chamfer at the cutout can be made simultaneously with the locking profile and the cutout in a single operation.
  • In the following preferred embodiments of the invention will be explained in more detail with reference to the drawing.
  • 1 is a schematic side sectional view of a floor covering according to a first embodiment of the present invention, with two interconnected floor panels;
  • 2 is a partial view of the right panel in 1 ;
  • 3 is a schematic side sectional view through a panel of a floor covering according to another embodiment of the present invention and
  • 4 is another schematic lateral section through a floor covering according to the embodiment of 3 showing two interconnected panels.
  • The floor covering 10 in 1 is composed of a number of adjacent panels, two of which are panels, namely a left panel 12 and a right panel 14 , in the connected state in 1 are shown. The two panels 12 . 14 are at their interconnected side edges 16 . 18 with interlocking interlocking profiles 20 . 22 provided, which are described in detail below. The interlocking of these locking profiles 20 . 22 prevents the panels from drifting apart 12 . 14 ,
  • The panels 12 . 14 of the floor covering 10 have the same stratification and each comprise a core 24 made of a plastic material such as polyurethane (PU) or polyvinyl chloride (PVC). Usually, this core contains 24 still fillers. He has due to the material properties of the plastic used to a certain elasticity. To ensure a dimensional stability of the core 24 is in the upper part of its center a glass fiber mat 26 retracted, extending horizontally through the core 24 extends.
  • On its top is the core 24 laminated by two cover layers. These are an upper wear layer 28 Made of a durable transparent plastic and a decorative layer 30 below the wear layer 28 , which is formed from a printed decorative film that can represent a wood or tile look. Due to the transparency of the wear layer 28 is thus the decor on top of the panels 12 . 14 visible, noticeable.
  • At the bottom of the panels 12 . 14 can the core 24 finally with a counterbalancing layer 32 Be equipped with a warping of the panels 12 . 14 prevented.
  • The stratification of the panels 12 . 14 , which is a wear layer 28 , a decorative layer 30 , a core 24 with a fiberglass mat 26 and a return layer 32 is substantially known and not the subject of the present invention.
  • This also applies essentially to the interlocking locking profiles 20 . 22 , which are joined together in the manner of a tongue and groove connection. The left panel 12 carries on its side edge 16 a female profile 20 , with a lower horizontal projection 34 , which is trough-shaped and at its right panel 14 facing outer edge 36 is formed with a raised web, which has a receiving area 38 on the lead 34 with a flat, horizontal bottom 40 and sloping, slightly curved outer walls 42 . 44 limited.
  • In this recording area 38 is a lead 46 of the complementary profile 22 the right panel 14 one. This lead 46 has a roughly trapezoidal cross-section, with a flat, horizontal bottom 48 to rest on the floor 40 of the recording area 38 , and bevelled, curved side walls 50 . 52 whose shape is about the side walls 42 . 44 of the recording area 38 correspond. In a gradation at the top of this tab 46 lies a complementary projection 54 at the top of the side edge 16 of the left panel 12 one. This lead 54 limits the recording room 38 partly upwards and in the assembled state of the panels 12 . 14 partly on the lead 46 the right panel 14 on.
  • The right panel 14 is on its top at the left panel 12 facing outer edge 18 with a cutout 60 Mistake. This cutout 60 has a flat, horizontal bottom 62 and a vertical sidewall 64 on the right panel 14 facing side. Overall, the cutout has 60 an approximately rectangular cross section, as in 1 can be clearly seen. The cutout 60 is deeper than the thickness of the wear layer 28 and the decorative layer 30 so that the wear layer 28 and the decorative layer 30 completely over the entire width of the cutout 60 away from the side edge 18 the right panel 14 are removed and the material of the core 24 is exposed. At the top of the panel 14 is the core 24 thus visible within the joint and forms a clear contrast to the rest of the intact surface of the panels 12 . 14 passing through the decorative layer 30 and the wear layer 28 is laminated.
  • In the assembled state of the panels 12 . 14 borders the projection 54 of the left panel 12 directly to the cutout 60 and closes it off laterally so that the dull, vertical outside 66 of the projection 54 a vertical wall forms, which together with the opposite wall 64 the right panel 14 and the floor 62 limited a groove with a rectangular cross-section. This groove provides a joint at the top of the panels 12 . 14 between the surface areas of these panels. Through the cutout 60 So it will be a gap between the panels 12 . 14 created without the panels 12 . 14 must be printed or pressed on their top. In addition, the joint impression is due to the contrast of the different materials of the core 24 on the ground 62 the joint and the decorative layer 30 strengthened. For example, the material of the core can be colored 24 a common sealing compound of a real joint between stone tiles look similar. Together with a stone decor of the wear layer 30 This results in a realistic impression of a floor covering made of floor tiles. Due to their depth, the joint is also tactile to the touch.
  • To the penetration of water into the joint or into the material of the core 24 To prevent, the cutout can 60 on the ground 62 be sealed with a seal coating, which is not shown in detail in the figures. This seal coating can also be dirt-repellent or executed in color.
  • For better representation of the shape of the cutout 60 for the formation of the fugue this is in 1 right panel 14 in 2 optional. Clearly recognizable is the rectangular shape of the cutout 60 that over the tab 46 is arranged. During this projection 46 at its upper, outer side edge, which is the adjacent panel 12 facing, a gradation 68 has, forms the cutout 60 a higher level further gradation, in the assembled state of the panels 12 . 14 remains free, as in 1 is clearly visible.
  • In 3 is another panel 112 represented, which is provided with a different locking profile. This locking profile 120 includes, similar to the locking profile 20 of the left panel 12 in 1 , a lower projection 134 , which on its top has an approximately trough-shaped receptacle 138 having. This recording area 138 has an approximately trapezoidal cross section and becomes the end of the projection 134 through a raised area 136 limited. Above the reception area 138 there is an upper side edge area 140 , which is approximately vertically formed and an elastic catch 142 for locking with a complementary profile, which in 3 not shown in detail. This locking profile 120 is intended to provide a complementary locking profile perpendicular to the receiving area 138 is pressed. In itself, this profile cross section is known.
  • At the top of the side edge 144 of the panel 112 is a cutout 160 provided with rectangular cross-section, the cut-out 60 in the panel 14 in 1 equivalent. Also this cutout 160 has a horizontal flat bottom 162 and a vertical sidewall 164 at the side of the cutout 160 on. In the assembled state with another panel, the cutout 160 is limited to the other side, by the cutout 160 formed a joint with rectangular cross-section. The cutout 160 extends here to a depth below the decorative layer 30 , so that the reason of the joint through the material of the core 24 is formed. In the assembled state, the effect of the joint thus formed is the same as that associated with 1 described.
  • The upper edges of the side walls 64 and 164 the cutouts 60 and 160 are according to 1 to 3 each with bevels, ie with bevels 70 . 170 Mistake. In this way, sharp edges on the edges of the recesses 60 . 160 avoided. In 1 indicates the top of the sidewall 66 at the lead 54 of the left panel 12 a similar chamfer 72 on.
  • The cutouts 60 . 160 can work together with the locking profiles 22 . 120 be performed in a single step, for example, by a combination tool, the same time the locking profiles 22 . 120 and the cutouts 60 . 160 ausfräst. As a result, an additional step is saved. Furthermore, the chamfers can also 70 . 170 together with the locking profiles 22 . 120 and the cutouts 60 . 160 getting produced.
  • 4 shows the panel 112 out 3 in the connected state with another panel 114 , The locking profile 120 of the panel 112 is in this case with a complementary locking profile of the panel 114 locked. The panel 114 has for this purpose a downward projection 146 at his the panel 112 facing side edge, in the receiving area 138 is included. As in the arrangement in 1 , forms the cutout 160 a groove of rectangular cross-section, laterally through the side walls at the upper edges of the panels 112 . 114 is limited.
