Description

  • The invention relates to a method for the production of mechanically connectable to a surface covering elements according to the features of claim 1 and a surface covering, produced by this method according to the features of claim 10.
  • Wall, ceiling, floor coverings, such as Prefabricated parquet, wooden floors or laminate floors, consisting of several rows of rectangular rectangular panels. Conventionally, the panels have on a longitudinal side and on a head side continuous grooves and on the respective opposite longitudinal side or head side continuous springs, which are adapted to the grooves form-fitting manner. Through the connection of tongue and groove the panels are laid.
  • It is known to form mechanical connection means on the grooves and springs, which engage with one another in a floor covering adjacent panels in latching engagement. As a result, a joint formation in the laid floor covering by expansion or shrinkage operations should be avoided. Adjacent to the tongue and groove of the panels are mating locking elements in the form of recesses, recesses or projections to hold bonded floor panels in the assembled position glueless. In general, the panels are rotated along their long sides into each other or clicked and then moved laterally, so that the locking strips engage the head sides. In order to achieve this intervention, light hammer blows can be exerted with the aid of an impact pad from the opposite side of the head. There is a risk that damage to the floor panels may occur even during the most careful work.
  • There are also solutions in which the abutting head pages do not need to be locked together by hammer blows, but by sliding spring elements. An example of this is a in the DE 20 2007 018 662 U1 described flooring in which identically formed panels can be locked together by a substantially vertical joining movement in the horizontal and vertical directions, wherein the locking in the vertical direction by at least one horizontally movable, integrally formed out of the core on a side edge spring element is effected, which snaps in the joining movement behind a locking edge extending substantially in the horizontal direction. 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 at its side edge to the core at at least one of the two ends. It is considered disadvantageous that the spring element for locking must first be acted upon by a horizontally acting force in order to push back the spring element before the built-up spring tension discharges and snaps the spring element behind the locking strip. The situation is similar in the case of EP 1 350 904 A2 described floorboards in which the spring, which must be attached to a front side of a floor element, must first be pushed back before it can snap into a predetermined locking for recording. In any case, a sufficiently large space must be available behind the spring, so that the spring can be pushed back before snapping.
  • From the DE 10 2009 041 297 A1 a lining of mechanically interconnectable elements is known, in which the locking of adjacent elements by a spring element can be effected, which is pivotable in the joining movement behind a substantially horizontally extending locking edge of the other element. The spring element slides when joining adjacent elements on a support surface opposite the locking edge of the adjacent element, wherein the support surface is inclined to the locking edge facing a laying plane and causes a horizontal displacement of the spring element behind the locking edge. The spring element may be integrally integral part of the associated panel of the same material. It is also disclosed that the spring element is a separate component that is attached to the bottom element.
  • The separate production of the spring element requires that the spring element is subsequently connected in a separate manufacturing step with the element. In a uniform material integral training this manufacturing step is eliminated. Separately manufactured springs must be manufactured with tight tolerances in order to have a sufficient accuracy of fit in combination with the tolerance fields of the associated floor element. However, a separately manufactured spring has the advantage that certain shaping steps can be performed on the spring, which in manufacture from the solid, d. H. in a material unit integral spring element, are not possible.
  • The invention has for its object to provide a method for producing mechanically connectable to a surface covering elements in which tighter tolerance values can be achieved in the connecting springs and with which the elements in question and connecting springs inexpensive to produce and install. Furthermore, a surface covering produced in this way should be pointed out.
  • The invention achieves this object with a method having the features of patent claim 1. A corresponding surface covering made of elements according to this method is the subject of patent claim 10.
  • The method according to the invention provides that the elements which can be connected to one another mechanically to form a surface covering are provided with an edge-side receiving groove which is provided for fastening at least one connecting spring. In the next step, at least one connecting spring is inserted into the receiving groove, wherein the connecting spring has a constant over its length cross-section. The material for the connecting spring used is a material with at least locally or partially different material properties than the material from which the interconnectable elements of the surface covering are made.
  • It is essential in the method according to the invention that a connecting spring is produced from a profile with a constant cross section, in particular from an extruded profile. Such a connecting spring can be produced very inexpensively by extrusion or co-extrusion and has a high manufacturing accuracy. In contrast to individual connecting springs, which are manufactured by injection molding, d. H. in a clocked process, connecting springs in the form of an extruded profile enable a continuous manufacturing process. The connecting springs can be produced in the extrusion process with very high and above all constant accuracy. With clocked methods also high accuracies can be achieved, however, the tool costs may be higher, especially in very complex, three-dimensionally designed connecting springs.
  • Another feature of the connecting spring used is that although it has a constant cross-section over its length but at least locally or partially different material properties than the material of the element in which the connecting spring is inserted and / or engages. This allows a functional adaptation of the connecting spring.
  • As an advantageous development of the invention is considered when the connecting spring is used in a first manufacturing step in the receiving groove, but is configured so that it does not yet have its final contour. Only in a further processing step, a material removing machining of the edge region of the element including the projecting out of the receiving portion of the at least one held in the receiving groove connecting spring is performed so that the edge region of the element and the at least one connecting spring is given a final contour. This preferred option provides for the installation of a cost-effective, quasi-raw connection spring, in particular in the form of a plastic endless strand. The subsequent profiling of the element provides a simultaneous material removing, in particular machining the connecting spring or the spring blank. In this procedure, there are no more shifts between the connecting spring and the receiving groove. The tools that are used for material removing machining are set so that exactly the desired contour can be achieved with very tight tolerances. Even manufacturing errors in the blank of the connecting spring or large tolerance fields in the production of the blank of the connecting spring play no role. When machining material removing the desired contours of the connecting spring can be achieved in the installed position. Errors or large tolerance fields in the blank of the connecting spring play no role in this context.
  • The term connecting spring is in the context of the invention therefore also representative of a blank of a connecting spring, which is brought into its final contour by removal of material in its final contour only after its assembly to one of the surfaces connectable to a surface covering, as well as representative of a connecting spring in her final contour. The respective meaning of the term results from the respective context.
  • The method according to the invention therefore initially provides for the production of the raw geometry and the receiving groove, then the attachment of the connecting spring into the receiving groove and finally the final profiling of the edge region including the profiling of the connecting spring or of the part of the connecting spring projecting out of the receiving groove, d. H. of the blank of the connecting spring.
  • A particular advantage of this method is that a suitable material for the connecting spring can be used, which has specific technical properties that differ in particular from those of the element, ie those of the support plate. The material for the connecting spring is in particular a plastic or a plastic-containing composite material, for. B. a fiber reinforced plastic. It is a material that allows processing of the edge area and the connecting spring by identical tools. Therefore, in an advantageous manner in a material removing machining of the edge region in a single pass at the same time the material of the element and the excess material on the blank of the connecting spring are removed.
  • The receiving groove is preferably formed as over the entire length of the edge side extending groove. The continuous receiving groove accordingly allows the inclusion of a continuous connecting spring. The connecting spring can be cut to length according to the length of the receiving groove. The connecting spring can also be introduced into the receiving groove in several sections. This has advantages when depositing a first element by angling against another, already laid element. When angling initially abuts an end-side portion of the connecting spring with a corresponding groove on the other element together, wherein the connecting spring is twisted in its longitudinal extent. In order to avoid this twisting or twisting of the connecting spring over the entire length and thus an increased restoring moment of the connecting spring, it is possible to provide a plurality of connecting springs, or to interrupt the connecting springs at certain intervals wholly or only in the region of their locking sections, so that the connecting spring overall has a greater flexibility. The restoring forces are smaller with shorter connecting springs or latching sections. This makes it easier to connect the elements.
  • It is possible to form a hinge section in the material removing machining of the connecting spring. The hinge portion is formed adjacent to a foot portion of the connecting spring held in the receiving groove. This joint portion can be formed by reducing the thickness of the connecting spring in certain areas. This reduction in thickness causes the connecting spring to deform in the region of the joint portion rather than in adjacent, thicker walled areas. There should be no significant deformation in the foot section. In areas of coupling provided for longitudinal sections of the connecting spring, d h. at the locking portion, should not take place as strong deformation as possible in the joint section as possible.
  • The connecting spring may have an upper recess in the area of the joint section on its upper side facing the visible side of the element and a lower recess on its underside. The bulges lead to a rejuvenation of the cross section of the connecting spring. The joint section is thus defined by this bottleneck. It is advantageous if the upper bulge is sized large, since the material is compressed in this area. On the bottom it comes to a stretch. Preferably, the lower protrusion in the engaged position is larger than the upper protrusion. In the unlocked position, the lower bulge is smaller than the upper bulge. The upper recess is sized so that the spring on the extended position in which the foot portion and the locking portion are in line, can be pivoted out without being plastically deformed or break.
  • The hinge portion defines a bending axis of the pivotable connecting spring. The deformability, the extent of the material's own restoring forces and the exact position of the bending axis of the joint axis of the connecting spring are significantly determined by the contouring in the region of the joint portion. With the method according to the invention, the joint portion is formed exactly the same over its entire longitudinal extension of the connecting spring. This is regarded as an advantage over individual, discretely produced connecting springs, which are introduced individually into the receiving groove and, due to the unavoidable manufacturing tolerances, do not necessarily have a joint axis aligned over all connecting springs.
  • In an advantageous development of the invention, it is provided that, in the case of material-removing machining of the connecting spring, a latching section is provided which is provided for coupling to an adjacent element of the surface covering. The locking portion differs from the hinge portion by its higher deformation resistance. In principle, it can consist of the same material as the joint section. Due to its larger wall thickness, however, it deforms much less in contrast to the joint section. The locking portion is provided with a corresponding contouring which is intended to engage with the adjacent element and to connect the two adjacent elements of the surface covering together.
  • The latching section preferably has no further joints, so that the connecting spring has a 3-part structure, comprising the foot section, the subsequent hinge section and the subsequent latching section.
  • The connecting spring is in its final contour or as a blank strand body in particular unwound from a roll and is cut to fit the size of the element before or after insertion into the receiving groove or appropriately cut to the length of the receiving groove. The connecting spring can also be referred to as endless strand. There is the possibility of the Endless strand present strand body with subsequent strand bodies, which are provided on a separate role to connect. The connecting spring is then an extruded profile with a constant cross section and a corresponding connection point between two successive extruded bodies. However, in the case of material removing machining, the connection point in its contour can likewise be adapted to the target contour of the connecting spring, like the remaining longitudinal sections of the extruded profile. The connecting springs can z. B. are glued together frontally.
  • In the method according to the invention are material residues that arise in the profiling of the edge regions of the element including the connecting spring. These material residues can be removed together and in particular sucked off. Although the mixture of the two materials is not just pure-grade materials, such material residues are often burned. The calorific value of the plastic component is comparatively high. There are also methods for material separation available, so that the material mixture readily separate into its components and can be fed to a targeted re-use in the context of recycling.
  • The material residues can also be used for the production of other components, eg. B. be pressed for wood-plastic composite components and for this purpose or blended with other materials and further processed.
  • The method according to the invention leads to individual elements which can be connected to one another to form a surface covering. According to claim 10, the connectable elements produced by the method are first processed so that the connecting spring has a hinge portion between a foot portion and a latching portion, wherein the latching portion is angled relative to the foot portion and against a resulting from the elasticity of the hinge portion restoring force in an engaged position with the adjacent element is displaced. The connecting spring thus has a certain spring force resulting from the choice and geometry of the material used. The exact contour of the joint portion and / or the at least one latching portion is made by material removing machining in the installation position of the connecting spring. The connecting spring of such elements can consist of a uniform composite material but also of composite materials which have a first material in the region of the latching portion, which has a lower elasticity than a second material in the region of the joint portion. In other words, elastic materials can be combined with less elastic materials in a manufacturing process of the connecting spring, so that the functional components of the connecting spring have matched to their respective function material properties. Therefore, connecting springs can also be used for elements with a particularly small thickness of z. B. 4 mm to 8 mm can be used. The elements of the surface covering may be, inter alia, elements for PVC floors, e.g. As carrier plates with top-side coverings based on PVC, as well as plastic or cement-based boards. The elements can be reinforced by fibers. However, these are preferably elements based on wood-based materials, in particular HDF boards.
  • Depending on the strength and locking method between adjacent elements a plurality of mutually spaced connection springs may be used in a receiving groove one edge to minimize the twisting of the individual connecting springs when angle and thus to simplify the laying of the individual elements to a surface covering.
  • The mechanical coupling of the individual elements is effected by the latching portion of the connecting spring. The latching portion is intended to be latched in connection with an adjacent element by contact with the adjacent element latching in a groove of the adjacent element, so that positive engagement is formed. In this case, a locking cam preferably engages the latching section with a latching recess in the groove. When locking the locking portion is pivoted. Preferably, the latching takes place through the latching recess in the groove, in which the latching section summarizes overall. But it can also be arranged a single recess on the latching portion of the connecting spring, in which summarizes an increase of the element for locking. The reverse variant with a recess on the element and an increase in the locking portion is possible.
  • The locking portion can be removed from the groove only by pivoting back nondestructively, but not by pulling parallel to the groove. The connecting spring is held in the locked state within the groove under tension. The locking portion is effectively clamped between the groove flanks as a groove. In this case, the locking cam is the counterpart to the upper groove flank. It is sufficient for a positive anchoring of the latching portion, if only an undercut in the form of the latching recess is arranged on the latching portion. The upper groove flank can be formed without an undercut. So that there is no height offset between the adjacent Elements comes, the locking portion is sufficiently rigid and large enough in cross section that he deformed only slightly elastic. Also, the joint area is so rigid that always a sufficiently large residual stress is maintained in the locked position, so that no play arises.
  • In a preferred embodiment of the invention, the latching portion of the connecting spring is oriented in the latching position in the direction opposite to the foot portion of the connecting spring. In a substantially horizontally oriented foot portion, this means that then the catch portion is oriented substantially horizontally.
  • The inventive concept is applicable to all floor, - wall and ceiling systems in which a topping on a support, which is in particular a wood-based panel such. As a 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 Deckschickt may in particular consist of a decorative paper with overlay, which determines the appearance of the elements , A floor covering can thus be a parquet floor, a finished parquet floor, a real wood floor or a laminate floor. Likewise, the elements of solid material, such. As wood flooring, wood elements, molded or molded plastic molding plates, in particular PVC moldings or gypsum boards.
  • The invention will be explained in more detail below with reference to exemplary embodiments shown schematically in the drawings, in which:
  • 1 and 2 in each case a cross section through the connecting region of two adjacent elements in different mounting positions, wherein 1 the still unlocked position shows and 2 represents the locking position;
  • 3 and 4 in each case a cross section through an element of a surface covering with a connecting spring, wherein 3 the connecting spring in the unprocessed state and 4 the connecting spring in an edited state shows and
  • 5 a cross-section through the connecting portion of two adjacent elements in the locking position with another embodiment of a connecting spring.
  • 1 shows a cross section through two elements in the form of panels. This may be a longitudinal or head-side cross section of the elements 1 . 2 act. The Elements 1 . 2 are identically configured, so the elements 1 . 2 to a surface covering, in particular a floor covering can be assembled. Identically configured in this context means that an element 1 . 2 at one end a connecting spring 11 has and at the other end a groove 20 for receiving the connecting spring 11 of the next element. 1 shows two adjacent elements 1 . 2 before the lock. The illustration on the left shows a first element 1 and on the right a second element 2 , which is intended for, with the first element 1 to be connected. The arrangement of the elements 1 . 2 Of course, it can also be reversed, ie mirrored around the vertical, so that the laying direction is reversed.
  • The 1 and 2 only show sectional views through the elements 1 . 2 , wherein the second element 2 parallel to the first element 1 is arranged. The second element 2 but can also be stored by pivoting about its non-illustrated longitudinal edge and with the other element 1 be connected by a pivoting movement. While pivoting, the elements stand 1 . 2 at an angle not equal to 180 ° to each other.
  • The first element 1 has a locking bar 3 on and the second element 2 a downwardly open dome channel 4 and a subsequent, downwardly directed dome bulge 5 , The locking bar 3 of the first element 1 is opposite the head side, which in this embodiment only as a page 6 is designated before. The element 2 becomes so opposite element 1 arranged that when lowering in the direction of arrow P dome bulge 5 of the second element with a dome channel 7 the locking bar 3 and the dome channel 4 of the second element 2 with a dome bulge 8th the locking bar 3 engaged. This area of the elements 1 . 2 essentially serves for positional orientation in the horizontal plane, whereby horizontally in the context of the invention the laying plane V corresponds to that with the mutually parallel upper sides 9 and subpages 10 of the elements 1 . 2 falls together.
  • Essential part of the elements of the invention 1 . 2 , which are connectable to a surface covering, is a connecting spring 11 , The connecting spring 11 comprises a substantially downwards, ie from the top 9 away directed tongue in the form of a latching portion 15 , The connecting spring 11 is in a receiving groove 12 at the right-hand element in the picture plane 2 used. The receiving groove 12 has mutually parallel groove flanks in this embodiment 31 . 32 ( 5 ). The orientation of the groove flanks 31 . 32 is not parallel to the laying plane V, but from the Nutmündung the receiving groove 12 towards Nuttiefsten slightly towards to the top 9 formed rising. The groove bottom of the receiving groove 12 is therefore closer to the top 9 of the element 2 as the Nutmündung.
  • The connecting spring 11 is only in the area of its in the image plane upper end with the element 2 connected. It can be seen that the connecting spring 11 one the receiving groove 12 engaging foot section 13 has, in this embodiment, the receiving groove 12 completely filled. At the foot section 13 closes outside the receiving groove 12 a thinner in cross-section area. This serves as a joint section 14 , The joint section 14 is formed by having a concave constriction in the form of a bulge 35 on the top 9 of the element 2 facing top 36 the connecting spring 11 and a bulge 37 on the bottom 38 having. At these bulges 35 . 37 or the joint section 14 joins in against the joint section 14 thickened catch section 15 at. The resting section 15 is provided over the joint section 14 relative to the foot section 13 to be pivoted. 2 shows how the rest section 15 the connecting spring 11 is pivoted into the locking position. The resting section 15 is on his top 16 smooth, ie not further profiled. A rest section 15 is altogether at its free lower end 17 wedge-shaped, with a blunt tip. On his the top 16 opposite bottom 33 owns the rest section 15 a locking cam 18 , which is intended for, in a recess 19 a groove 20 at the left in the picture plane element 9 to understand. Another recess 34 is located adjacent to the Rastnocken 18 on the side to the hinge section 14 out.
  • 2 clarifies, as when lowering the right in the picture plane element 2 the connecting spring 11 is deformed. The resting section 15 pushes it with its lower end 17 in the area of the mouth of the groove 20 on a leading edge 21 adjacent the recess 19 , The bottom 33 the Rastabschnittes 15 with the locking cam 18 slides on the leading edge 21 of the other element 1 off, leaving the foot section 13 around the joint section 14 is pivoted. The lower end shifts 17 the Rastabschnittes 15 in the picture plane to the left until the locking cam 18 behind the leading edge 21 holds and in the recess 19 comes to the plant. At the same time, the leading edge holds 21 in the recess 34 of the rest section 15 , 2 shows the elongated arrangement of the connecting spring 11 in the locking position.
  • In the locking position, the right-hand element in the image plane lies 2 on a console 22 of the left-hand element in the image plane. The console 22 is located above the groove 20 for receiving the connecting spring 11 is provided. Forces, in the direction of the arrow P on the right in the image plane element 2 act through the console 22 in the image-left element 1 transfer. Conversely, forces acting in the direction of the arrow P on the left in the image plane element 1 act, over the locked connection spring 11 between the two elements 1 . 2 transfer. In the horizontal direction, the forces are essentially on the engagement of the locking bar 3 with the dome channel 4 transfer. There are support surfaces for this purpose 23 . 24 , Which are oriented substantially perpendicular to the laying plane and the contact between the Kuppelwulst 8th and the dome channel 4 produce. In this embodiment, the support surfaces stand 23 . 24 not perpendicular to the laying plane, but are slightly inclined, so that when lowering the right in the picture plane element 2 the front ends 6 . 24 of the elements 1 . 2 pressed against each other.
  • In the locking position, a pulling apart of the two elements in the horizontal direction, ie in the laying plane also prevented by the groove 20 into which the foot section 13 the connecting spring summarizes, is undercut. The recess 19 creates next to the leading edge 21 an undercut, in which the locking cam 18 summarizes. At the same time is also the resting section 15 through the recess 34 provided with an undercut, leaving it behind the leading edge 21 summarizes. In the horizontal direction, ie in the direction of the laying plane V, the connecting spring 11 therefore not be pulled out. It can only be in the groove 20 swung in and out again. For this reason, there is an upper groove flank 25 shorter than a lower groove flank 26 whose end is determined by the location of the leading edge 21 adjacent the recess 19 Are defined. To the leading edge 21 closes quasi in extension of the groove flank 26 a sliding surface 27 at. This sliding surface is to the groove 20 inclined down so that the foot section 13 in the direction of the leading edge 21 and the recess 19 slide off and when placing the right in the image plane element 2 swiveling into the groove 20 introduced and can lock with this. An automatic "unlatching" does not occur because the restoring forces of the connecting spring 11 are too small for this.
  • 3 shows a method step of a method for producing mechanically connectable to a surface covering elements. The individual elements, as in the 1 and 2 are shown are in their peripheral areas 28 profiled in a continuous process to allow a mutual locking. 3 shows the border area 28 of the element 2 , In the border area 28 is a spring blank 29 arranged. The spring blank 29 is different from the manufacture connecting spring 11 as they are in the 1 . 2 and 4 is shown, in that only the foot section 13 already in the designated receiving groove 12 is used. The one from the receiving groove 12 outstanding part or section of the spring blank 29 becomes in situ during processing, ie in the illustrated position of the connecting spring 11 in the receiving groove 12 processed. For this purpose, a material-lifting tool, in particular a milling tool is used.
