Definitions

  • the invention relates to a device for locking two interconnected floor panels, which are both identical and have a core, a top and a bottom, a first side edge and a second side edge opposite this, and on the top the first side edge of the first floor panel to the abuts the second side edge of the second floor panel, in the second side edge a horizontal groove extending into the core is formed with an upper wall, an inner wall and a lower wall, the lower wall being formed by a lower lip protruding on the first side edge, which has at its outer end a projection pointing in the direction of the upper side with a first locking edge, and at least one locking element is inserted in the region of the connection point of the two floor panels, and a spring projecting outwards on the second side edge is seen, which has at its outer end a step forming a spring tip and at its end facing the core a vertically extending second locking edge, the second locking edge being the outer wall of a vertical groove open to the underside, into which the projection engages , and the locking takes
  • Such a device is for example from the DE 202 05 774 U1 known.
  • the locking element is inserted into the groove so that it protrudes from one side with its free end and is locked with its other end.
  • a third floor panel is placed on and connected to the two interconnected floor panels, the third floor panel abutting the free end of the locking element and thereby pressing the locking element in the longitudinal direction into the groove, thereby the locking element bends in the groove in the transverse direction and, due to the bending in the transverse direction, also engages in a second groove which is provided in the opposite second floor panel, as a result of which the first and second floor panels are then locked together.
  • the DE 10 2007 032 885 B4 discloses a device for locking two interconnected floor panels in which not only the locking element, but also a compression element is inserted as a mechanical spring element in the groove, which has a plurality of spring arms connected to one another in an articulated manner, so that the side of the locking element facing the groove base and the the locking element facing side of the compression element are designed to engage with each other.
  • the locking element is formed obliquely on its side protruding from the groove. If two panels are connected to each other in the vertical direction, the locking element is pressed into the groove and, when the panels are connected, springs back into a recess provided in the newly created floor panels and then locks the two floor panels in the vertical direction.
  • a locking of two interconnected floor panels which consists of an insert which can be inserted into a locking groove formed in the connection point.
  • the two floor panels are connected by a horizontal joining movement.
  • a tongue is formed on one side edge of the panel and a connecting groove corresponding to the tongue is provided on the opposite side edge.
  • a groove open at the top is made in the top of the tongue and a groove open at the bottom in the upper wall of the connecting groove. If the spring is inserted into the connecting groove, the two grooves overlap and then form a locking groove into which the locking element can be inserted.
  • the locking element can be triangular or x-shaped in cross section with four spring lips that form.
  • a locking device of two interconnected floor panels is also known, in which the adjoining panels are locked in the horizontal direction by means of a compressible locking element.
  • the panels do not abut each other at the top, but an elastic element is inserted between the connecting edges in order to build up tension in the connection so that a gap is avoided.
  • the locking element consists, for example, of silicone and can be deformed in all directions in space.
  • the DE 44 06 295 A1 discloses a female connector construction for panel cladding, in which the female connector is resilient along one of its two longitudinal edge regions engaging in a panel groove and has a greater height than the panel groove width. As a result, the elastic longitudinal edge area for the insertion into the associated panel groove becomes elastically flexible and is supported on the groove walls in the inserted state. In the visible area of the panel cladding, the surface of the female connector presses against the outer groove edge.
  • brackets are designed as separate components and are secured in vertically extending pins in two adjacent panels. Horizontal movement of adjacent panels is prevented by two rubber or plastic buffer elements that are inserted into the brackets.
  • a generic device for locking two interconnected floor panels is characterized in that the locking element is compressible in the vertical direction and incompressible in the horizontal direction.
  • This configuration makes it possible to compress the locking element with the underside of the tongue and press it into the groove in the lower lip during the vertical joining movement of the new panel to be created. If the length of the lower lip from the inner wall of the horizontal groove to the projection is greater than the length of the tongue from the spring tip to the locking edge on the tongue, a space is formed when the tongue is inserted into the groove between the projection and the locking edge, so that the locking element can decompress again and engages (springs in) into this space and the locking groove thus formed. The locking in the horizontal direction then takes place against two at least substantially vertical locking edges or on two vertical locking surfaces.
  • the core of the floor panels can be made of any material. Wood material and wood-material-plastic mixtures (WPC) of pure plastic or a mixture of plastic and mineral components, a mixture of plastic, mineral and wood components or purely mainly mineral cores are suitable, so that gypsum fiber boards or cement fiber boards can also be used as a carrier board for any coating come.
  • WPC Wood material and wood-material-plastic mixtures
  • the fibers do not necessarily have to be wood fibers.
  • the second locking edge should preferably run slightly inclined to the top of the floor panel and / or bevelled at the bottom with a chamfer.
  • the inclination of the second locking edge is slightly less than 90 °, preferably 85 ° to 89 °.
  • the side of the locking element assigned to the second locking edge can then also be correspondingly inclined, the inclination angles having to be similar but not identical.
  • first and second locking edges run parallel to one another and in particular at an angle of less than 90 ° to the upper side, form almost vertical locking surfaces that can also absorb high tensile forces in the horizontal direction. A loosening of the locking element in the locking groove and an associated gap formation in the top of the floor, which was produced from a plurality of connected floor panels, is effectively excluded.
  • This device is particularly suitable for square-shaped panels.
  • a profile can be provided for angling a new panel to the row of panels that have already been laid, as shown in FIG DE 102 30 818 B3 , in the WO 01/75247 A1 or in the WO 01/02669 A1 is disclosed.
  • This profiling can also be used on the long long side if rectangular panels with the profiling according to the invention are formed on the short transverse side.
  • a groove adjacent to the projection is preferably provided in the lower lip for at least partially receiving the at least one locking element.
  • the locking element can be firmly connected to the lower lip, preferably glued and already attached to the panel by the manufacturer in order to simplify handling. In this case too, the locking element can be inserted into the groove provided in the lower lip and fastened there.
  • a slightly inclined and / or chamfered second locking edge or locking surface makes sense in the vertical direction so that the elastic locking element can spring back again, even if the second locking edge is too far back due to manufacturing tolerances (in the direction of the first locking edge) would and could otherwise prevent springing.
  • the panels would still be locked, but the locking element might not be completely decompressed.
  • the locking element could also be made slightly oblique on the surface pointing towards the second locking edge.
  • the locking element is preferably shown slightly obliquely at least on its side facing the second locking edge or is provided with a chamfer.
  • a plurality of locking elements can preferably be provided spaced apart from one another.
  • the locking element in the vertical direction, it can be configured, for example, in the form of a tube or cylinder and thus inserted into the groove in the lower lip, so that its longitudinal axis is oriented in the direction of the spring tip, that is to say in the direction of the horizontal joining movement.
  • the spring element can then be compressed in the vertical direction and, if necessary, also diverge in the horizontal direction running in the longitudinal direction of the side edge, but compression in the horizontal joining direction (this is also the axial direction of the pipe or cylinder) is not possible, so that the connection holds securely ,
  • the locking element preferably consists of a base plate on which a plurality of parallel spaced lamellae are arranged so as to be elastically pivotable.
  • a force acts in the direction of the slats protruding from the base plate, they bend in the direction of the base plate, whereby the compressibility of the locking element is established.
  • the slats pivot back elastically, the locking element decompresses and the lock is established.
  • a cover plate can also be provided against which the slats abut at the bottom. In both cases, the slats should be arranged at a slight angle to ensure the compressibility of the locking element.
  • the relatively smooth upper side of the locking element formed by the cover plate offers the advantage that the lamellae cannot cling to the rough surface of the core material.
  • the locking element can also be formed by a plurality of rectangular elements arranged one behind the other, two of which are connected to each other at an edge and, in the decompressed position, are arranged at an angle ⁇ to one another.
  • the locking element is then designed in the form of a strip.
  • a device for locking two interconnected floor panels both of which are of identical design and have a core, a top side and a bottom side, a first side edge and a second side edge opposite this, and two floor panels connected to one another form a locking groove in the connection point, the peripheral wall of which is formed to a first part from the core of the first panel and to a second part from the core of the second panel, and a locking element is inserted in the locking groove
  • the locking element can be compressible in one of the horizontal direction or the vertical direction and then in the other of the vertical direction or the horizontal direction to be incompressible.
  • the locking element can be used both for locking two panels in the horizontal direction and in the vertical direction.
  • the locking element is compressible in the horizontal direction or whether it is compressible in the vertical direction depends only on its installation position. If it is to lock two panels in the horizontal direction, it must be compressible in the vertical direction and incompressible and rigid in the horizontal direction; if it should lock in the vertical direction, it must be compressible in a horizontal direction and incompressible and rigid in the vertical direction.
  • Figure 1 shows a floor panel 1 or 2 in cross section with the opposite side edges I, II, which are profiled so that two identically designed floor panels 1, 2 are connected to each other and can be locked to each other in the horizontal direction H and vertical direction V.
  • the profiling described below is preferably formed on the transverse side of rectangular floor panels 1, 2. It is particularly suitable for square floor panels 1, 2.
  • the floor panels 1, 2 are connected to one another by first connecting a first row of panels 01, 02 at the side edges I, II and then in a second row of panels the first panel 1 initially with its Longitudinally angled into the already laid row of panels 01, 02 and then pivoted downward in an essentially vertical joining movement onto the sub-floor. Then the second panel 2 is angled with its long side into the already laid row of panels 01, 02, then also swung downward in an essentially vertical joining movement onto the sub-floor and then with its second side edge II to the first side edge I of the second Row laid first panel 1 is created.
  • this will be described in more detail.
  • the floor panel 1, 2 consists of a core 3 made of wood-based material or a wood-based material / plastic mixture and can be coated on its top 10, 20 and / or bottom 11, 21 with a decorative layer.
  • the floor panels 1, 2 are identical. In the following, we speak of the floor panel 1 if the first side edge I is affected and of the floor panel 2 if the second side edge II is affected.
  • the panel 1 On its first side edge I, the panel 1 is provided with a horizontal groove 4 which is introduced in the horizontal direction H and which forms an upper wall 4.1, an inner wall 4.2 and a lower wall 4.3.
  • the panel 2 On its opposite second side edge II, the panel 2 is provided with a spring 2.1, which forms a spring tip 2.3 as a result of a step 2.2 which is produced when the side edge II is milled from the top 20 to the bottom 21.
  • the lower wall 4.3 is formed by the upper side 1.4 of a lower lip 1.1 projecting over the side edge I, which is provided at its outer end with a projection 1.2 pointing towards the upper side 10, on which a first extending parallel to the inner wall 4.2 of the horizontal groove 4 Locking edge 1.5 is formed.
  • the distance between the first locking edge 1.5 and the inner wall 4.2 is greater than the length of the foot 2.6 of the spring 2.1 from the spring tip 2.3 to the second locking edge 2.5.
  • Figures 2a to 2d illustrate the joining movement for connecting the second panel 2 to an already installed panel 1, which essentially takes place by pivoting vertically down onto the sub-floor (cf. Figures 4 ).
  • the second panel 2 is first angled into an already installed row of panels 01, 02 and then lowered with its spring 2.1 onto the lower lip 1.1 of the first panel 1 until the spring 2.1 rests with its foot 2.6 on the upper side of the lower lip 1.1 ( Figure 2b ). Then the second panel 2 is displaced in the horizontal direction H, so that the tongue 2.1 is inserted into the horizontal groove 4 until the contact surfaces of the side edges I, II abut one another.
  • a gap remains between the spring tip 2.3 of the spring 2.1 and the inner wall 4.2 of the horizontal groove 4, which can serve as a dust pocket.
  • a groove 1.3 adjacent to the projection 1.2 is additionally introduced into the lower lip 1.1, into which the locking element 5 is inserted.
  • the locking element 5 is compressible in the vertical direction V.
  • the foot 2.6 of the spring 2.1 compresses the locking element 5.
  • the locking element 5 when the spring 2.1 has penetrated into the horizontal groove 4 and the connecting surfaces of the side edges I, II abut against one another, spring back into the ones formed as the locking groove 7 between the first locking edge 1.5 and the side locking edge 2.5 gap.
  • the chamfer 2.7 ensures that the locking element 5 can also spring into the locking groove 7 after its compression. If the chamfer 2.7 is not to be attached, it would be advantageous to let the locking edge 2.7 run slightly obliquely to the upper side 20. The same effect can also be achieved if the elastic locking element 5 is slightly inclined on its side facing the locking edge 2.5, as would be the case, for example, with the locking elements 5 having a round cross section, as shown in FIGS Figures 7 and 8 are shown - or has a chamfer 5.4 ( Figures 5a, 6a ). In any case, however, it can be assumed that the locking element 5 springs back into the locking groove 7. Even if this should only happen partially, locking takes place in the horizontal direction H.
  • the locking element 5 can be used as a separate component that is inserted into the groove 1.3 at the time of laying, but it can also be inserted into the groove 1.3 at the factory and fastened there. For example, be glued.
  • Figures 5a to 5c show a first embodiment of a decompressible spring element 5, which has a rectangular shape in cross section.
  • a plurality of slats 5.2 protruding in the vertical direction from a base plate 5.1 are elastically connected to the base plate 5.1.
  • the slats 5.2 run slightly obliquely with respect to the base plate 5.1. They can be angled in the direction of the base plate 5.1 and then pivot back into their upright position when no more force is exerted on them in the vertical direction V (arrow P 3 ).
  • a cover plate arranged parallel to the base plate 5.1 can be provided (not shown) on the underside of which the slats 5.2 abut.
  • Figures 6a to 6c show a further embodiment of a locking element 5, which consists of a multi-angled strip that can be flattened by a vertical force and springs back to its original shape after relief and is then decompressed again.
  • the strip consists of a plurality of rectangular elements 5.3 arranged one behind the other, two of which are each connected at an edge and are arranged at an angle ⁇ to one another in the decompressed position.
  • FIGS 7a to 7c show a locking element 5 which is tubular and corrugated, and analogous to that in Figure 6 Locking element 5 shown can be compressed and decompressed again by appropriate rebound.
  • Figures 8a to 8c show a particularly simple form of a locking element 5 which is tubular or cylindrical.
  • the locking element 5 When force is applied, the locking element 5 is compressed and takes it in Figure 8b Figure 1 shown. After relieving the force, it springs back and takes on the tubular or cylindrical cross-section again.
