Definitions

  • the invention relates to a covering of mechanically interconnectable elements.
  • Wall, ceiling and floor coverings such as Prefabricated parquet, wooden floors or laminate floors, consist of several rows of mostly rectangular and partly square panels in their configuration.
  • the panels have on a longitudinal side and on a head side through grooves and on the respective opposite longitudinal side or head side continuous springs, which are adapted to the groove form-fitting manner. Through the connection of tongue and groove the panels are laid.
  • abutting head sides are not locked together by hammer blows, but by sliding spring elements.
  • An example of this is a floor covering, as in the DE 20 2007 018 662 U1 is described.
  • Identically formed panels are locked together by a substantially vertical joining movement in the horizontal and vertical directions.
  • the locking in the vertical direction is effected by at least one horizontally movable, integrally formed out of the core spring element, which snaps in the joining movement behind a substantially horizontally extending locking edge.
  • the at least one spring element is free in the direction of the upper side and in the direction of the opposite side edge relative to the core and connected in its side edge at at least one of the two ends to the core.
  • the spring element must first be subjected to locking with a horizontally acting force to push it back before the built-up spring tension discharges and snaps the spring element behind the locking bar.
  • a coating of mechanically connectable elements in which the spring element is an integral part of the element and has a crimping.
  • an elastic material is arranged, which has a greater elasticity than the spring element.
  • the crimp has opposing walls which are at least partially, in particular over the entire surface coated with the elastic material, wherein the coatings are arranged in the unlocked state at a distance from each other and are in the locked state in contact with each other to stick together.
  • the invention is therefore based on the object to show a covering of mechanical interconnectable elements, in which the coupling of the spring element with the associated element in the pivoted state is even safer, so that the connection between the two elements is even more stable.
  • a positive and / or non-positive locking snap connections are to be understood in particular, in which two components into each other and are pressed into each other so that friction creates a frictional connection and thereby an automatic sliding of the surfaces in contact is prevented.
  • a positive connection occurs, d. H. geometries interfere with each other, which prevent an automatic relocation of the mutually engaged components.
  • Means are provided to improve the positive or non-positive engagement, either by providing the mating surfaces at least partially with a coating having a high coefficient of friction and / or by engaging the mating surfaces in a manner be profiled that slipping is hampered.
  • the means for locking are at least partially formed as a male piece for engaging in a trained as a mother piece recording on the element.
  • the reverse variant is possible in which the means for locking are at least partially formed as a nut piece, for receiving a trained as a father piece projection on the element. Since more material for forming a nut piece, ie for forming a groove or a concave recess, is generally available on the element, there is preferably a receptacle designed as a nut piece on the element.
  • both are formed on the spring and the element, ie there are on the element both a trained as a nut piece receptacle, as well as serving as a fatherpiece part for engagement in a nut piece on the spring element, which nonetheless as a means for locking additionally has a father element. Due to the close proximity of the two components, this results in an S or Z-shaped Contour, which have the necessary for a positive engagement undercuts or groove surfaces.
  • the spring element can also be swung back again, as well as in the locked position, the elastic material is not separated from the spring element, but because he keeps the spring element still on the element.
  • the spring element can even be solved several times from the end position, d. H. be released, and then locked again.
  • the only difference in the second and subsequent pivoting relative to the first pivoting is that the spring element in the starting position is no longer an integral part of the element, but after the initial pivoting and the breakage of the predetermined breaking point between the initial and the final position is free to pivot.
  • the elements according to the invention it is therefore possible to lock the elements together by means of a substantially vertical or pivoting joining movement in the horizontal direction and in the vertical direction.
  • the element to be applied must be folded down for connection to a third element.
  • the said spring element can be used on the side of the element to be laid on the side of the strin.
  • the spring element is then pivoted into the frontal, already laid element.
  • the spring element breaks at the predetermined breaking point, is held over the elastic material and is pivoted on further folding of the element to be laid in the end position where the spring element locked with the now swung down element and remains in this detent position.
  • Header pages are the short element pages.
  • the profiling can in principle be provided on all sides, that is to say on the top sides and the longitudinal sides, of the preferably rectangular elements.
  • At least one spring element is provided on one side of an element. It is conceivable, at head ends that can not be pressed down parallel to already laid panels, but are folded down, the spring element form several pieces. That is, on one of the elements a plurality of spring elements are arranged on one side, which may be spaced apart from each other or may also be immediately adjacent. Adjacent spring elements can be coupled to one another via an elastic material. The separate spring elements are gradually pivoted behind a locking edge of a groove of the adjacent element. The locking edge extends substantially in the horizontal direction, so that the two interlockable elements against displacement in the vertical direction, d. H. perpendicular to the laying plane, are secured. Additional locking strips may be provided on the elements to provide, in addition to the vertical locking, also the locking in the laying plane, i. H. in a horizontal direction.
  • the means for locking the spring element are at least partially uniform material integral part of the spring element. That is, they are made of the same material as the spring element, which in turn is made of the same material as at least the core of the element.
  • the element itself can be multi-layered, as is typical for floor coverings. Manufacturing technology, it is easiest that the locking means are formed at least partially uniform material integral with the spring elements. If possible, such means for locking by milling processes in a continuous process can be made easily and quickly.
  • an abutment shoulder is formed on the element next to the receptacle or next to a projection, d. H. the coupling means, which engage with the means for latching the spring elements.
  • the abutment shoulder extends substantially horizontally, that is to say in the laying plane.
  • the spring element with maximum depth engages in the corresponding groove of the adjacent element.
  • the groove wall of the groove which is closer to the upper side of the element and which carries the locking edge, is preferably formed in alignment with the contact shoulder in the installed position.
  • the contact shoulder and the top groove wall form the upper limit for the spring element. If a force is introduced from the element carrying the spring element into the contact shoulder and thus into the spring element from above, the force is introduced into the adjacent element via the groove wall of the groove of the adjacent element opposite the locking edge, so that both elements are in the coupling region be pressed down evenly.
  • an undercut may be formed in the groove of the adjacent element, ie in the groove, on which also the locking edge is formed and in which engages the spring element.
  • Such an undercut is a special feature, since the spring element for locking in the vertical direction does not have to engage in an undercut.
  • the spring element can engage in this undercut, with the result that by the spring element also a further Verrieglung can be effected in the laying plane. This engaging behind the undercut leads in addition to an improved form-fitting.
  • a means for positive and / or non-positive engagement may be formed in the region of the free end of the spring element. It is in particular a projection, which engages behind the undercut during pivoting of the spring element during locking. As a result, the spring element is secured against being pulled out in the direction of the mouth of the groove.
  • the means for locking relative to the own spring element can be embodied, for example, as a bead which is rounded in cross-section and can be pivoted in a receptacle configured as a rounded groove.
  • the bead and the groove can be dimensioned differently in cross section, so that the bead, similar to a push-button principle, grasps into the groove.
  • the bead has a different radius or a different degree of curvature on its surface than the receptacle for the bead.
  • an undercut can be formed in the receptacle.
  • the radii of the receptacle and bead deviate only insignificantly from one another in the area of the contact surfaces. It is essential that the spring element can be easily pivoted into the groove, overcomes a certain resistance during pivoting and then introduced into the groove, there snaps and automatically remains.
  • the means for latching on the spring element can also be embodied as a bead which is substantially rectangular in cross-section and which engages in a substantially rectangular groove as a receptacle. Also here The dimensions of groove and bead may differ slightly from each other, so that the desired positive and / or frictional connection is achieved.
  • the penetration depth of the bead into the receptacle can be limited by the fact that the spring element laterally engages the receptacle on the element. As a result, the spring element engages only with limited depth in the respective recording. Thus, not only is it ensured that the spring element is in the correct position relative to the receptacle, but also that the spring element does not pivot too far and that the elastic material is not excessively squeezed.
  • the spring element is supported on both sides of the receptacle, namely on the one hand by the abutment shoulder explained above and on the other hand by a arranged on the other side of the receiving abutment surface.
  • the means designed as a bead for latching against the groove bottom of the receptacle so that there is a further limitation.
  • the configuration of the receptacle or the means for latching is chosen such that the spring element when pivoting into an end position with the element to which the spring element is attached by means of a holding force is locked, which is greater than a restoring force of the elastic material.
  • the spring element can not be automatically pulled back to its original position. It has to be manipulated from the outside, ie actively released from the locking position. This is possible by moving the adjacent elements against the joining direction. This means that the element with the spring element must be raised. The spring element is thereby strongly pressed against the locking edge.
  • the restoring force of the elastic material is supported so far that the holding force in the region of the means for locking is no longer sufficient to hold the spring element in the end position.
  • the spring element now begins to slide along the locking edge out of the groove, so that the element with the spring element can be fully raised and can be relocated if necessary, which is extremely easy to install.
  • the support surface of the adjacent element is concavely curved, while the free end of the spring element in the contact region with the support surface is at least partially convexly curved.
  • the concave and convex curvature are not congruent, but coordinated so that the spring element engages during pivoting substantially backlash in the groove of the adjacent element and grasps behind the locking edge.
  • both surfaces are inclined in the inventive arrangement. This has the advantage that the spring element in the initial state can be substantially perpendicular to the laying. This has manufacturing advantages.
  • the concavely curved support surface or the support surface which is inclined at least relative to the laying plane, causes the spring element to pass more easily from the starting position into the end position than to a support surface which extends horizontally.
  • the force initially necessary for the predetermined breaking of the spring element can be applied very easily, without the laying process being hindered. Any fragments from the predetermined breaking point fall down and can collect in the concave curved support surface, which is virtually formed as a trough, without affecting the locking process or disturb.
  • the spring element has a crimping, in which the elastic material is arranged.
  • An elastic material has a greater elasticity than the spring element, so that it does not break during bending.
  • the each other opposite walls in the region of the crimp can be at least partially, in particular over the entire surface coated with the elastic material, wherein the coatings are arranged in the unlocked state at a distance from each other and are in the locked state in contact.
  • the mutually contacting coatings may stick together when in contact with each other.
  • the elastic material can therefore be an adhesive.
  • the covering according to the invention is not necessarily a floor covering. It can also be a wall or ceiling covering.
  • the locking is done not only vertically to the laying level, but also in the laying level.
  • a locking edge exhibiting element has a bearing element under the spring element cross-locking bar.
  • the locking strip is suitable to secure the adjacent elements against tensile stress in a laying plane.
  • the additional locking strip primarily absorbs horizontal tensile forces, ie tensile loads in the laying plane. This ensures that no joint gap remains at the top. The entry of liquid and dirt in any gaps is prevented.
  • the material for the spring element or the proportion of the element from which the spring element is made may be both a wood material, ie, it may be wood or wood fiber material, or a material made of wood as the base material is, such as liquid wood.
  • the spring element or the proportion of the lining, from which the spring element is made it may also be a composite material.
  • the use of mixed plastics is just as possible as the use of materials based on thermoplastic or thermosetting plastics.
  • the inventive concept is applicable to all floor systems and wall systems in which a top covering on a support, which in particular is a wood-based panel, such. an MDF or chipboard is arranged, such as real wood coverings, laminate, support with painted surfaces as a topping, linoleum, cork on support plates, etc.
  • the cover layer may in particular consist of a decorative paper with overlay, which determines the appearance of the elements.
  • a floor covering may thus be a parquet floor, a finished parquet floor, a real wood floor or a laminate floor.
  • elements of solid materials such as wood planks, wood elements, molded plastic mold plates, plastics, moldings or gypsum boards are suitable.
  • the inventive idea does not only relate to the connection of identical elements.
  • one of the elements to be connected is configured as a panel and a second element as a frame component.
  • the panel is placed in the assembly of one or more frame members existing frame structures during assembly and locked with his head and / or sides.

  • This area of the elements 1, 2 essentially serves for positional orientation in the horizontal plane, horizontally in the context of the invention corresponding to the laying level V, which coincides with the mutually parallel upper sides 9 and lower sides 10 of the elements 1, 2.

It can be seen that the spring element 11 in the region of its upper side now not only in the element 2, but also with the element 1 in a manner in communication, so that an additional train protection in laying plane V is created. This is achieved in that the projection 38 engages in the undercut 39 and at the same time engages the means for locking 16 in the receptacle 17 of the other element 2. The spring element 11 thereby causes not only a catch in the vertical direction but also in addition in the horizontal direction, ie in the laying plane.
  • FIG. 12 shows that even such a profiled element 1 can be used with a fixed tongue and groove connection.
  • the spring 34 is exemplified as a fixed spring, which virtually replaces the movable spring element. Neither the undercut 39, nor the concave support surface 19 are disturbing. It can still be realized a fixed tongue and groove connection in a conventional design.
  • FIG. 13 shows two elements 1, 2 in the locking position.
  • the spring element 11 is in turn held on the right element 2 via an elastic material 22.
  • the means for locking 16 on the spring element 11 in this case is not a protruding bead, but are formed as a cross-sectionally triangular groove, whereas on the element 1, a projection 40 is formed, which engages in the matching groove.
  • the father piece is now on the element 2 while the associated nut piece is formed on the spring element 11.
  • there is a contact shoulder 33 on the element 2 which is arranged at a different height level, ie higher in the vertical direction above the projection 40.
  • a corresponding support strip 41 serves as a mating surface for the abutment shoulder 33.
  • the adjacent elements 1, 2 are aligned with each other in height and supported against each other.
  • a Switzerland Schweizer in the direction of the laying plane is again via a locking bar 3 on the left in the image plane element 1 and a corresponding Kuppelwulst 5 on the other element. 2
  • the embodiment of the FIG. 14 is different from the one of FIG. 13 in that the means for locking 16 are formed on the spring element 11 both as a father piece and as a nut piece. This results in a zigzag-shaped toothing between the latching means 16 and corresponding counterparts, ie receptacles 17 and projections 40 on the element 2. Another difference is that the means for latching 16 and the projection 40 and the receptacle 17 are arranged in the engagement position to the end face 31 of the right-hand element 2 in the image plane. This results in that the right in the image plane element 2 is not displaced by the means for locking 16 in height.
  • the free end within the groove 24 is supported on an upper groove flank 25, wherein the locking edge 28 is disposed very close to the means 16 for locking.
