In order to improve the connection between the first and the second side edge, it is provided that the locking portion (22, 22 ', 22' ', 22' '') from a foreign element (12, 12 ', 12' ', 12' '' ) is formed.

Description

  • The invention relates to a panel of a floor covering, in particular a Laminatfußbodenbelags, having a first side edge and a second side edge, wherein the first side edge and the second side edge are arranged opposite to each other and formed corresponding to each other, that the first side edge by an approximately vertical movement with the second side edge of a similar panel can be connected, wherein the first side edge has a first locking lug with a predominantly upwardly facing first locking surface, wherein the first locking lug is provided on a locking portion, wherein the second side edge of a second locking lug with a predominantly downwardly facing second Has locking surface and wherein the first and the second locking surface in the connected state engage behind each other in a direction parallel to the panels.
  • Panels of this type are already known. However, there is still a need for optimization with regard to the locking of the side edges. To lock the side edges, the locking lugs must be forced past each other with elastic deformation of the side edges, so that the locking lugs then engage behind each other and the side edges can permanently lock against each other. The side edges should be on the one hand in the field of locking lugs on the one hand to be quite elastic, so there is no damage to the side edges when connecting the side edges by a movement approximately vertical to the floor covering. On the other hand, the corresponding areas should not be too elastic, so that the side edges remain securely and permanently locked together. It should not come to a misalignment of the tops of the adjacent panels. This is unsightly and can lead to the damage of the corresponding edges or surfaces. Such an offset of the upper sides can occur, in particular, at a point load.
  • In the EP 1 415 056 B1 a panel is described, which can be locked via a foreign element in the vertical direction with a similar panel. For this purpose, the foreign element provided on a first side edge has a movable locking finger, which engages in a groove provided for this purpose in a second side edge of an adjacent panel. The foreign element is inserted in the first side edge in a groove on a locking element, which is why the groove must be made narrow and therefore the stability of the connection between the first side edge and the second side edge is low. In addition, in the region between the groove and the locking finger of the foreign element chips or other contaminants can penetrate, which can lead to damage of the first and / or the second side edge when connecting corresponding panels.
  • Therefore, the present invention has the object, the aforementioned and previously described in detail panels to design and further develop that the connection between the first and second side edges of corresponding panels can be improved and problems caused by chips or other contaminants.
  • This object is achieved in a panel according to the preamble of claim 1, characterized in that the locking portion is formed of a foreign element.
  • The panel may be formed as a laminate panel and preferably a carrier plate of a wood material, for example in the form of a medium-density fiberboard (MDF), a high-density fiberboard (HDF) chipboard or an Oriented Strand Board (OSB) have. The support plate may also be formed of a plastic or a wood-plastic compound (WPC) of a wood material and a plastic, wherein the wood material can be accommodated in a lumpy or fibrous form in a plastic matrix.
  • On the carrier plate, a decorative and a protective layer may be provided. The protective layer is provided to protect the decor from abrasion. The decor is printed either on a resin-impregnated paper or directly on the need-based primed support plate. To protect the decoration, at least one resin layer may additionally be provided, which if necessary may comprise fiber materials (overlay) and / or hard solid particles such as corundum. In order to prevent sagging of corresponding panels, a counter coat made of a lacquer or resin layer or a Gegenzugschicht of a resin-impregnated kraft paper may be provided on the underside.
  • Furthermore, still a third and a fourth side edge may be present, which are also provided corresponding to each other and opposite each other. If necessary, the third side edge and the fourth side edge can be connected to each other by mutual angle. The downward bending of the one side edge opposite to the other side edge can produce a movement substantially from top to bottom relative to an adjacent first and an adjacent second side edge, which a corresponding movement are connected to each other at the same time.
  • Under a foreign element, an element of the first side edge is considered, which is not worked out of the material of the support plate and / or not integrally connected to the support plate. Preferably, foreign elements are made of other materials than the carrier plate of the panels. In this way, the properties of the connection between the first side edge and the second side edge can be better adjusted.
  • In order to connect the foreign element captive with the first side edge, it may have a groove in which the foreign element is partially received, preferably in a form-fitting manner. The foreign element can be inserted into the groove, plugged, wedged, glued or otherwise secured. It lends itself, for example, when the part of the foreign element received in the groove has ribs which are inclined somewhat in the direction of the slot opening and are set against the slot flanks in this orientation. Then these ribs would have to be bent first to pull the foreign element out of the groove. Here, for example, a so-called pine cone profile comes into question. As a result, the foreign element can be held frictionally and / or positively in the groove.
  • The groove can be made relatively wide, for example, if it is not provided on a locking element of the first side edge, since here, for example, no additional forces must be absorbed by the first side edge. In addition, the groove can be provided so with sufficient distance from the distal end of the first side edge, so that the foreign element can be arranged completely below a portion of the side edge. Then the foreign element is well protected against entry of chips or other contaminants from above.
  • Alternatively or additionally, the groove or the part of the first side edge adjoining the groove can also have a stop face for the foreign element, in particular for the part of the foreign element accommodated in the groove. The abutment surface is designed in such a way that the foreign element or the part of the foreign element received in the groove abuts against the abutment surface when the foreign element or the part of the foreign element received in the groove is pulled out of the groove, before the groove accommodated in the groove Part of the foreign element has left the groove. The abutment surface is therefore preferably inclined with respect to the extension direction of the part of the foreign element received in the groove. The more the abutment surface is inclined relative to this extension direction and / or the larger the abutment surface is formed, the greater the forces that can be transmitted by the foreign element in the extension direction to the abutment surface. It is particularly preferred if the foreign element is secured by the stop on the stop surface against unintentional removal from the groove. In particular, the abutment surface can ensure that the part of the foreign element received in the groove is held positively in the groove. It is advisable if the stop surface is formed by a step, a shoulder and / or projection along at least one groove flank of the foreign element partially receiving groove.
  • Additionally or alternatively, however, the stop surface can also serve to position the foreign element in the groove. This happens, for example, by exerting on the foreign element a pull-out force, which ensures that the foreign element rests against the stop surface. The corresponding pull-out force can be exerted, for example, without any further action in the connected state of the side edges on the foreign element. Alternatively or additionally, the part of the foreign element received in the groove may have been inserted into the groove under prestress. This bias can exert a restoring force in the extension direction of the received in the groove portion of the foreign element. The restoring force can ensure, for example, that the foreign element is positioned in the connected state as predetermined with respect to the first side edge, preferably by the part of the foreign element received in the groove resting against the stop surface.
  • The bias voltage may be generated by, for example, compression or bending of the foreign element, for example, because the groove is slightly too small or insufficiently shaped to allow the part of the foreign element received in the groove to be absorbed without bias. The bias voltage forms a force which tries to move the part of the foreign element received in the groove at least partially out of the groove in the extension direction and thus holds the foreign element in contact with the stop surface. In the manner described, for example, a self-locking and / or a self-positioning of the foreign element can be achieved. It also makes sense if the stop surface is formed by a shoulder and / or projection along at least one groove flank of the groove partially receiving the foreign element.
  • A bias for better connection of the side edges and / or the more accurate positioning of the foreign element in the groove of the first side edge, wherein the foreign element is preferably on abuts the abutment surface of the first side edge, may alternatively or additionally also be achieved by the connected to the part of the foreign element provided in the groove adjacent part of the foreign element, which may be the locking portion but does not have, compared to in the groove provided part of the foreign element is pivoted to generate a restoring force, preferably about a pivot axis which extends longitudinally to the first side edge and thus along the foreign element. The part of the foreign element which adjoins the part of the foreign element accommodated in the groove is preferably pivoted in the direction of the second side edge. When the part of the foreign element adjacent to the part of the foreign element received in the groove faces downwardly, the downwardly facing part of the foreign element may be pivoted upwards and / or forwards and vice versa. The resulting restoring force tries to pull out about the recorded in the groove part of the foreign element in the extension direction of the groove, but this is prevented for example by the abutment surface of the first side edge. The abutment surface can thus contribute as needed to a positioning of the foreign element relative to the first side edge. An investment of the foreign element on the additional contact surface is not mandatory.
  • If necessary, the angle α between the part of the foreign element provided in the groove and the part adjacent to the part of the foreign element provided in the groove, which may also be the locking part of the foreign element, may be smaller in the unconnected state than in the connected state , This is achieved, for example, in that the part of the foreign element adjoining the part of the foreign element provided in the groove abuts against the first side edge when inserted into the groove and as a result is pivoted. For example, when the part of the foreign element adjacent to the part of the foreign element accommodated in the groove protrudes downward from the groove, the foreign element may abut the lower lip of the groove, preferably the distal end surface of the lower lip of the groove. If, for example, a stop surface is still provided, for example, on the upper groove flank, the part of the foreign element received in the groove is possibly tended to be pulled out of the groove and pressed against the stop face. For example, the foreign element will assume a defined position. Alternatively or additionally, the foreign element can also be wedged in the groove and / or jammed so that the foreign element is better held in the groove.
  • In a preferred embodiment of the panel, the angle α between the part of the foreign element provided in the groove and the part of the foreign element adjacent to the part of the foreign element provided in the groove in the connected state is smaller than the angle β between the lower edge of the groove and distal end, in particular the end surface, the lower lip of the groove. With a corresponding configuration of the first side edge, a free space is provided in the connected state between the foreign element and the lower lip of the groove into which the locking section can move when connecting the first and second side edges. In this case, the locking portion or another part of the foreign element at least partially abut the lower lip of the groove to prevent the locking portion can come under load out of engagement with the locking lug of the second side edge and / or the locking lug of the second side edge engages behind significantly less , Also in this connection, the above-described configuration of the part of the foreign element adjacent to the part of the foreign element provided in the groove may equally apply to the locking part when it adjoins the part of the foreign element accommodated in the groove. The attachment of the foreign element to the lower lip of the groove may alternatively or additionally serve to adjust the bias of the foreign element and / or the wedging of the foreign element in the groove in a defined manner, since the foreign element reaches a defined deformation by the contact with the lower lip ,
  • The part of the foreign element adjacent to the part of the foreign element which is provided in the groove and which may or may not be the locking section may alternatively also be pivoted downwards and / or to the first side edge, so that a restoring force is generated which Locking portion presses against the locking lug of the second side edge. The connection of the side edges is then tight and therefore stable. For example, it can be ensured that a defined connection state is achieved and accidental disconnection of the side edges is avoided.
  • It is particularly easy to manufacture, if the groove has a rectangular cross-section. In this case, the longitudinal extension of the groove from the opening of the groove in the direction of the groove bottom of the groove form an angle with the top of the panel. This angle is preferably between 10 ° and 90 °, preferably between 15 ° and 65 °. The larger the angle, the sooner it is possible to separate the panels in the extension direction by the foreign element slides out of the groove. By contrast, smaller angles can lead to a more durable and more stable connection of the first and second side edges. Opposite the part of the Foreign element is the locking portion of the foreign element preferably in a direction outward so in the direction of an adjacent panel, but without having to protrude relative to the support plate or the panel top to the outside. Thus, the function of the locking portion, namely the locking of an adjacent side edge, can be optimally utilized. In this case, it may be provided, for example, that the locking section of the foreign element protrudes parallel to the panel in the distal direction relative to the part of the foreign element provided in the groove.
  • To stabilize the floor covering and in particular also the connection between the first and the second side edge, the locking section can be supported in the connected state of the first side edge with the second side edge on the ground. This is achieved, for example, in that the locking section extends down to the plane of the underside of the panel.
  • The foreign element may alternatively or additionally also be provided such that the foreign element is supported in the connected state of the first side edge with the second side edge on the second side edge. The support of the foreign element is preferably carried out at a predominantly in the direction of the distal end of the second side edge facing surface of the second side edge. In this way it can be achieved that the foreign element is positioned as desired in the connected state of the first and the second side edge. An additional locking surface between the foreign element and the second side edge is not required. It is also advisable if the foreign element is supported in an approximately rectilinear extension of the groove on the second side edge. For example, the foreign element is pushed as far as desired into the groove from the second side edge.
  • The foreign element can also engage in a recess of the second side edge and, if necessary, be supported on a surface of the recess of the second side edge. This may be the case at a surface that points predominantly in the direction of the distal end of the second side edge. However, a foreign element may additionally or alternatively come into contact with at least one predominantly upwardly and / or predominantly downwardly facing contact surface of the receptacle. By means of this at least one contact surface on which the foreign element is present or can come to rest, an additional locking of the foreign element with the second side edge can be achieved in relation to a separation of the first and second side edges from one another. However, additionally or alternatively, a positioning of the foreign element can be achieved in such a way that the locking engagement of the first locking surface and the second locking surface is supported. This can be achieved, for example, in that the foreign element is positioned even better or more stable by abutment against the contact surface and / or held in position.
  • Alternatively or additionally, the locking portion and the part of the foreign element received in the groove can be connected directly or indirectly via a hinge element. The hinge element may in this case be designed such that the locking section is pivoted away from the adjacent panel when connecting the first side edge to the second side edge around the hinge element. Alternatively or additionally, the locking portion can also be pivoted about the hinge element to the adjacent panel or pivoted back to the starting position, so as to lock the side edges together. The hinge element thus preferably forms a pivot axis parallel to the top of the panel.
  • The latching or locking the locking portion with the corresponding locking lug, if necessary, produce a clearly audible noise, such as in the form of a click, to indicate to the publisher that the side edges are intended to be connected.
  • To improve the stability of the connection between the first and the second side edge, the hinge element may be arranged farther away from the panel upper side than the locking lug of the foreign element.
  • Instead of providing a hinge element, however, the locking portion may also be designed so that it is displaced and / or compressed in the direction of the panel plane during connection. As a result, it is not necessary to pivot the locking section about the hinge element, for which reason a corresponding hinge section can be dispensed with. In this context, it is particularly preferred if, during the joining in the direction of the panel plane, the locking section can be displaced and / or compressed by 2% to 25% of its extent in precisely this horizontal direction. It is further preferred if the locking section can be displaced and / or compressed by approximately 4% to 20%, for example by cooperation with the second side edge in the panel plane. Particularly good properties of the connection were obtained when the locking portion at least 6% and at most 15% of its extension in the direction of the panel level can be moved and / or compressed. Then, the side edges can be easily connected to each other without the risk of accidentally separating the side edges.
  • In order to adjust the elasticity of the locking portion when connecting the first and second side edges and / or adjusting the resistance of the locking portion to lifting of the first side edge from the second side edge, a length may be provided between the locking portion and the part of the foreign element provided in the groove be provided to the first side edge extending cavity in the foreign element. The cavity is preferably closed perpendicular to the first side edge and is preferably embraced by the foreign element. It is particularly preferred in this connection if, on the one hand, the cavity can be compressed and / or compressed on the one hand when connecting the first side edge to the second side edge and / or on the other hand, then enlarge and / or expand again. The compression of the cavity then facilitates, for example, the connection, while the subsequent enlargement of the cavity can assist in locking the side edges in the vertical direction.
  • The foreign element is made of a plastic material for providing suitable properties, in particular for providing suitable elasticities. It is particularly simple when the foreign element is made of an extruded material and / or extruded itself. The foreign element can then be separated for mounting on the panel of an endless profile. The foreign element may be co-extruded from the groove-accommodated part and the locking portion for better adjustment of the properties and / or independent variation of the characteristics. In particular, in the case of a coextrusion, the production of the foreign element made of different plastics comes into question.
  • In order to make the second side edge compact, so that unnecessary waste is avoided, the second locking lug may be provided at the distal end of the second side edge. Alternatively or additionally, the. second locking lug provided on a locking element, which can contribute to the stabilization and longevity of the connection between the first and the second side edge.
  • For example, the locking element may extend substantially in the direction of the panel top. In addition, if necessary, the locking element in the connected state of the first side edge with the second side edge at least partially engage in a groove which may be open in the direction of the panel bottom. When the locking portion protrudes below the opening of such a groove, the connection can be stable and the side edges can be made compact.
  • Alternatively or additionally, the first side edge may have a key extending substantially in the direction of the panel underside, wherein the second side edge may, if required, have a fitting groove corresponding to the keyway. For instance, in the connected state of the first side edge with the second side edge, the feather key can engage in the fitting groove and thus likewise contribute to a locking of the first with the second side edge, even if these preferably have a locking parallel to the panels and perpendicular to the connected side edges is.
  • To lock the side edges, the feather key and the fit groove in the connected state of the first side edge may have corresponding contact surfaces with the second side edge. The contact surfaces may be designed to lock the first side edge and the second side edge in a direction parallel to the panel.
  • It can also be provided that the feather key and the fit groove in the connected state of the first side edge with the second side edge each have two corresponding contact surface pairs and that these contact surface pairs the first side edge and the second side edge in two opposite directions parallel to the panel and, if necessary perpendicular to lock the connected side edges.
  • Alternatively or additionally, for the mutual support of the side edges in the connected state of the first side edge and the second side edge, the distal end of the feather key rest on the groove bottom of the fitting groove.
  • The side edges can be particularly compact and the connection can be realized particularly closed when a contact surface pair of feather key and fitting groove is arranged in the connected state of the first side edge with the second side edge in the horizontal direction of the panel at the level of the outer edges of the visible side of the panel top.

  • The common flanks on the one hand by the feather key 9 and the adjacent groove 10 and on the other hand of the locking element 18 and the passnut 19 , each form a contact surface 20 . 21 , The contact surfaces 20 . 21 are aligned with each other and lie in the connected state of the first side edge 5 with the second side edge 6 to each other. Through the abutting stop surfaces 7 adjacent to the panel tops and also adjacent contact surfaces 20 . 21 become the first and the second side edge 5 . 6 mutually in opposite directions each parallel to the panels 1 and perpendicular to the side edges 5 . 6 locked.
  • Even if in the illustrated and so far preferred panels 1 the first side edges 5 always very similar and the second side edges 6 are formed substantially the same, is intended by the representation of the preferred panels 1 can not be expressed that the same, previously described elements of the first side edge 5 and / or the second side edge 6 actually always have to be present. The playback of very similar panels 1 is only the better comparability of in the 1 to 10 illustrated, preferred embodiments of the panels 1 , in particular with regard to the shape of the groove 11 for receiving the foreign element 12 and the formation of the foreign element 12 , serve.
  • So it could for example on the locking element 18 , the passnut 19 and / or the contact surface 20 . 21 be waived. Alternatively, however, the arrangement of these elements could be modified with each other. The same applies accordingly in the same way for the feather key 9 and / or the locking groove 10 , It is also only preferred that the locking lug 15 at a distal end of the second side edge 6 is provided, and only additionally preferred that the second side edge 6 under the locking nose 15 is set back, so not below the locking lug 15 protrudes and / or the locking lug 15 not undercut. Ultimately, it is also possible to use individual elements of the described first side edge 5 and the second side edge 6 pick out or otherwise combine with each other, as long as this does not lead to solutions that are technically nonsensical to those skilled in the art.
  • A locking of the first side edge 5 with the second side edge 6 , in particular to a lifting of the first side edge 5 from the second side edge 6 that is, in a direction substantially or at least approximately perpendicular to the interconnected panels 1 is by a mutual engagement behind the first and second locking lug 14 . 15 reached. This is the first side edge 5 from the top to the second side edge 6 postponed. This pushes the second locking lug 15 against the first locking lug 14 attached to a locking section 22 is positioned. The second locking nose presses 15 the locking portion 22 in a direction away from the distal end of the first side edge 5 wherein the locking portion, for example, one between the in the groove 11 recorded part 13 of the foreign element 12 and the locking portion 22 provided hinge element 23 can be swung away. This allows the second locking lug 15 at the first locking nose 14 glide by. Once this has happened, for example, the locking section pivots 22 around the hinge element 23 in the direction of its original position and locked in this way for the publisher audible with the second locking lug 15 , Will the locking section 22 not a hinge element 23 swung back, the locking section 22 otherwise moved back in the direction of the starting position to the second locking lug 15 to lock. Then the is in the 1 to 10 illustrated connected state of the first and the second side edge 5 . 6 achieved by the first and the second locking surface 16 . 17 the two locking lugs 14 . 15 abut each other.
  • Alternatively to the procedure described above, could with appropriate redesign of the in the 1 to 10 shown second side edge also in addition to or instead of the second locking lug 15 an area of the second side edge directly or indirectly adjacent to the locking nose 6 against the first locking lug 14 and / or the locking portion 22 butt to the locking section 22 in a direction away from the distal end of the first side edge 5 to move when the first side edge 5 with the second side edge 6 is connected.
  • To support the first and second side edges 5 . 6 against each other is in the in the 1 to 3 illustrated and so far preferred panels 1 the feather key 9 adapted to be in the connected state of the side edges 5 . 6 on the groove bottom of the pass groove 19 support. In addition, the locking section is supported 22 with its lower distal end on the surface of the floor covering.
  • The difference in the 1 to 3 represented panels 1 is based on the arrangement of the groove 11 for partially receiving and fixing the foreign element 12 and the formation of the foreign element 12 itself. The groove 11 basically has a longitudinal extension from its opening to the bottom of the groove. This longitudinal extent of the groove forms in its extension with the top of the panel 1 Floor or an angle γ, in the in the 1 shown panel is 45 °. The same angle γ is in the in the 2 shown panel 30 °, while the angle γ in the in the 3 shown panel is 15 °. The flatter the groove 11 is aligned, the stronger is the in the groove 11 provided part 13 of the foreign element 12 in the groove 11 wedged when the first side edge 5 is loaded in the extension direction upwards. The lower is also the risk or possibility that the foreign element 12 out of the groove 11 is pulled out. Due to the inclination of the groove 11 and the connection between the part received in the groove 13 of the foreign element 12 on the one hand and the groove 11 On the other hand, if necessary, can be adjusted that interconnected panels 1 disconnect by the first side edge 5 opposite the second side edge 6 is lifted, the foreign element 12 at least partially out of the groove 11 is pulled out. At the same time, the connection between the foreign element should be 12 and the groove 11 be so stable that accidentally separating each other laid panels 1 is prevented.
  • That in the 4 represented and so far preferred panel 1 is very similar to the ones in the 1 to 3 represented panels 1 educated. However, it is a foreign element 12 ' with an upstanding locking portion 22 ' intended. The locking section 22 ' is on a hinge element 23 ' attached, near the Bottom of the foreign element 12 ' is arranged, which points in the direction of the ground. On the the locking section 22 ' opposite side of the hinge element 23 ' is the foreign element 12 ' in the same way in a groove 11 pushed in, as this is related to the 1 to 3 has been described.
  • Towards the bottom, the locking section is supported 22 ' on a tongue 24 the first side edge 5 ' starting from below the foreign element 12 is arranged and in the illustrated us preferred panel 1 Tapered towards the distal end. Through the appropriate tongue 24 can from the connection of the first side edge 5 ' with the second side edge 6 high pull-out forces are absorbed in the vertical direction.
  • For connecting the first side edge 5 ' with the second side edge 6 , becomes the first side edge 5 ' on the second side edge 6 postponed. In this case, first of all the locking section 22 ' from the locking nose 15 the second side edge 6 around the hinge element 23 ' in the direction of the groove 11 pivoted, wherein the hinge element in the illustrated and so far preferred panel to the tongue 24 borders. When the locking nose 14 of the locking section 22 ' the locking nose 15 the second side edge 6 has happened, this pivots by the elastic restoring force of the hinge element 23 ' in the direction of their initial position to the outside and away from the groove 11 , Then engages under the locking lug 14 at the locking portion 22 ' the locking nose 15 on the locking element 18 , Preferably, the locking portion lies on the tongue provided under it 24 the first side edge 5 ' on. If necessary, but also not too great decency between the locking portion 22 ' and the tongue 24 be tolerated when connecting the first side edge 5 ' with the second side edge 6 then not too unstable.
  • In the 5 is a panel 1' with a modified first side edge 5 '' and a modified foreign element 12 '' shown. The foreign element 12 '' sits with a rear end in a groove 11 the first side edge 5 '' which runs essentially horizontally, but in principle could also run more inclined to the horizontal. The groove 11 has at its outer end a paragraph 25 on. This paragraph 25 defines a stop face pointing into the groove 26 for the foreign element 12 '' , The foreign element 12 '' lies on this stop surface 26 on or comes into contact with this stop surface 26 when in the groove 11 recorded part of the foreign element 12 '' in the extension direction from the groove 11 would be moved. Paragraph 25 and the stop surface defined by this 26 are in the in the 5 represented panel 1'' not so great that due to a positive connection, a withdrawal of the foreign element 12 '' out of the groove 11 could certainly be prevented, although this would be possible. Then that would be the introduction of the foreign element 12 '' in the groove 11 very expensive. It gets through the stop surface 26 of the paragraph 25 However, that reaches the attachment of the foreign element 12 '' at the stop surface 26 the further extraction of the foreign element 12 '' out of the groove 11 opposes another resistance that may be large enough to accidentally pull out the foreign element 12 '' out of the groove 11 to avoid.
  • Alternatively or additionally, by the stop surface 26 a permanent positioning of the foreign element 12 '' be reached in a predefined position. This is even more true when referring to the foreign element 12 '' in the connected state and / or when connecting a force is applied, which is the foreign element 12 '' against the stop surface 26 suppressed. This force can be achieved by the formation of the second side edge 6 on the foreign element 12 '' be transmitted.
  • This force can also be a restoring force caused by the foreign element 12 '' itself is provided because the foreign element 12 '' for example in the groove 11 is at least partially compressed or deformed, as in the 6 is shown. In this case, the foreign element is 12 '' For example, at least partially slightly thicker than the groove 11 high at the appropriate places, leaving the foreign element 12 '' generates a restoring force that the foreign element 12 '' in the direction of the groove 11 out and against the stop surface 26 suppressed.
  • In the in the 6 represented panel 1'' is the foreign element 12 '' not quite up to the groove bottom in the groove 11 inserted. The foreign element 12 '' So, for example, when connecting the first side edge 5 '' with the second side edge 6 further into the groove 11 pushing in, connecting the first side edge 5 '' with the second side edge 6 would facilitate. Due to the restoring force as a result of the further insertion of the foreign element 12 '' in the groove 11 accompanying deformation of the foreign element 12 '' , that will be in the groove 11 recorded part 13 of the foreign element 12 '' at least partially moved back in the opposite direction (extension direction) until the foreign element 12 '' against the stop surface 26 of the paragraph 25 in the upper flank of the groove 11 and a self-positioning of the foreign element 12 '' causes.
  • In the in the 6 represented panel 1'' joins the in the groove 11 recorded part 13 of the foreign element 12 '' a downward-facing part 36 of the foreign element 12 '' at the in the illustrated foreign element 12 '' in the hinge element 23 '' passes. The to the in the groove 11 recorded part 13 of the foreign element 12 '' subsequent part 36 of the foreign element 12 '' can be one along the first side edge 5 '' running pivot axis forward in the direction of the second side edge 6 be swung. The foreign element 12 '' can be so far into the groove 11 be inserted that the appropriate part 36 of the foreign element 12 '' against the distal end of the lower lip 28 the groove 11 abuts and accordingly against the further inserted into the groove part 13 of the foreign element 12 '' is pivoted. The angle α between that in the groove 11 recorded part 13 of the foreign element 12 '' and the adjoining part 36 of the foreign element 12 '' is therefore lower in the unconnected state than in the connected state. By pivoting the foreign element 12 '' a restoring force is generated, which tries to be in the groove 11 recorded part 13 of the foreign element 12 '' out of the groove 11 pull it out. The restoring force may additionally or alternatively to the restoring force described above due to the further insertion of the in the groove 11 recorded part 13 of the foreign element 12 '' to be provided. The foreign element 12 '' but not from the groove 11 pulled out, but only comes into contact with the stop surface 26 that of a paragraph 25 in the form of a step in the upper groove flank of the groove 11 is formed. In addition, the angle β between the lower edge 35 the groove 11 and the endface 27 the lower lip 28 the groove 11 greater than the angle α between that in the groove 11 recorded part 13 of the foreign element 12 '' and the adjoining part 36 of the foreign element 12 '' , The part received in the groove 13 of the foreign element 12 '' has the same orientation as the lower flank 35 the groove 11 , This results in a free space 34 between the end surface 27 the lower lip 28 the groove 11 and the adjacent part 36 of the foreign element 12 '' , In addition, a defined position of the foreign element results 12 '' which the locking of the first side edge 5 '' and the second side edge 6 guaranteed. An excessive deflection of the locking element 12 '' at increased load of the compound can be avoided.
  • The two in the 5 and 6 foreign elements shown 12 '' is common that in the groove 11 recorded part 13 of the foreign element 12 '' and the locking end forming the opposite end 22 '' via a hinge element 23 '' connected to each other. With this hinge element 23 '' the locking section is supported 22 '' and ultimately the foreign element 12 '' even on the ground on which the panels 1'' be moved.
  • To the connection between the first side edge 5 '' and the second side edge 6 to stabilize, which borders the locking portion 22 '' opposite region of the hinge element 23 '' on a steep end surface 27 the lower lip 28 the groove 11 at. The endface 27 closes at the 5 represented and so far preferred panel 1'' an angle greater than 60 ° with the horizontal. When in 6 represented and so far preferred panel 1'' The angle is slightly flatter and is at least 50 °. This ensures that the foreign element 12 '' when connecting to the second side edge 6 a little further into the groove 11 can dodge. Subsequently, the foreign element can 12 '' if necessary, again from the groove 11 Press out.
  • In the 7 is a panel 1'' represented essentially in the 5 represented panel 1'' equivalent. One difference is that at the first side edge 5 '' in the 7 represented panels 1'' the groove 11 is arranged a little higher than the one in the 5 represented panel. Because of this high similarity of the panels 1'' be in the 5 and 7 the same reference numerals are used. In the foreign element 12 '' of the 7 is also an extension 29 provided by means of this the foreign element 12 '' in the connected state of the first side edge 5 '' and the second side edge 6 on the second side edge 6 supported. In the illustrated and so far preferred panel 1'' the foreign element is supported 12 '' at a predominantly in the direction of the distal end of the second side edge 6 pointing surface 30 from. In addition, this area is 30 in the illustrated and so far preferred panel 1'' on the locking element 18 intended. Furthermore, in this case, the extension 29 a substantially rectilinear extension of the groove in the groove 11 recorded part 13 of the foreign element 12 '' , The extension 29 relies therefore in the connected state of the first and second side edge 5 '' . 6 more stable against the groove bottom. Other embodiments of the extension 29 or foreign element 12 '' would be conceivable in principle. In any case, provides the additional investment of the foreign element 12 '' over the extension 29 on the second side edge 6 to a more reliable positioning of the foreign element 12 '' in the connected position of the first and second side edges 5 '' . 6 ,
  • The in the 8th represented panels 1'' essentially correspond to those in the 6 represented panels 1'' , so that the same reference numerals are used. Also with these panels 1'' has the foreign element 12 '' an extension 29 on, which is essentially a straight line extension of the groove 11 recorded part 13 of the foreign element 12 '' forms. In addition, the recorded in the groove part 13 of the foreign element 12 '' at the Connecting the two side edges 5 '' . 6 a little further into the groove 11 be pushed in, as this is in the 8th is shown. When connecting the two side edges 5 '' . 6 namely pushes the locking element 18 the second side edge 6 the locking portion 22 '' and the extension 29 inside. In this case, a restoring force is generated, which is the foreign element 12 '' again something out of the groove 11 comes out if the two side edges 5 '' . 6 connected to each other. The foreign element 12 '' is then, if necessary, on the stop surface 26 of the paragraph 25 in the upper groove flank of the groove 11 at. At the same time, the extension 29 of the foreign element 12 '' in a recess 31 the second side edge 6 , For example, in the locking element 18 , intervene. There is the extension 29 in the illustrated and so far preferred panel 1'' at a predominantly upwardly facing contact surface 32 at. This becomes the foreign element 12 '' against the upper groove flank of the groove 11 pressed and there for example at the stop 26 of the paragraph 25 positioned and held. This can ultimately lock the two side edges 5 '' . 6 Still be improved with each other.
  • In the in the 8th represented panel 1'' may alternatively or additionally a bias of the foreign element 12 '' be achieved by joining the in the groove 11 recorded part 13 of the foreign element 12 '' a downward-facing part 36 of the foreign element 12 '' connects, the foreign element shown 12 '' in the hinge element 23 '' passes. The to the in the groove 11 recorded part 13 of the foreign element 12 '' subsequent part 36 of the foreign element 12 '' can be one along the first side edge 5 '' running pivot axis forward in the direction of the second side edge 6 be swung. The foreign element 12 '' can be so far into the groove 11 be inserted that the appropriate part 36 of the foreign element 12 '' against the distal end of the lower lip 28 the groove 11 pushes and is pivoted accordingly. The angle α between that in the groove 11 recorded part 13 of the foreign element 12 '' and the adjoining part 36 of the foreign element 12 '' is therefore lower in the unconnected state than in the connected state. By pivoting the foreign element 12 '' a restoring force is generated, which tries to be in the groove 11 recorded part 13 of the foreign element 12 '' out of the groove 11 pull it out. The restoring force may additionally or alternatively to the restoring force described above due to the further insertion of the in the groove 11 recorded part 13 of the foreign element 12 '' to be provided. The foreign element 12 '' but not from the groove 11 pulled out, but only comes into contact with the stop surface 26 that of a paragraph 25 in the form of a step in the upper groove flank of the groove 11 is formed. In addition, the angle β between the lower edge 35 the groove 11 and the endface 27 the lower lip 28 the groove 11 greater than the angle α between that in the groove 11 recorded part 13 of the foreign element 12 '' and the adjoining part 36 of the foreign element 12 '' , The part received in the groove 13 of the foreign element 12 '' has the same orientation as the lower flank 35 the groove 11 , This results in a free space 34 between the end surface 27 the lower lip 28 the groove 11 and the adjacent part 36 of the foreign element 12 '' , In addition, a defined position of the foreign element results 12 '' which the locking of the first side edge 5 '' and the second side edge 6 guaranteed. An excessive deflection of the locking element 12 '' at increased load of the compound can be avoided.
  • In the 9 is a different embodiment of a foreign element 12 ''' shown, with a specific formation of the first side edge 5 '' , which is essentially the formation of the first side edge 5 '' according to 6 equivalent. Basically, this kind of foreign element could 12 ''' but also in other previously illustrated and further embodiments of the first page edge 5 . 5 ' . 5 '' be provided. The foreign element according to the 9 has no hinge member to which the locking portion 22 ''' can be pivoted to the two side edges 5 '' . 6 to connect with each other. Nevertheless, the required flexibility and / or elasticity of the foreign element 12 ''' for locking the two side edges 5 '' . 6 to be able to provide, has the foreign element 12 ''' a cavity 33 on, extending along the first side edge 5 '' extends and perpendicular to the longitudinal extent of the first side edge 5 '' from the foreign element 12 ''' is encompassed.
  • Be the two side edges 5 '' . 6 interconnected, the locking element 18 the second side edge 6 the foreign element 12 ''' squeeze so that the front, as a locking section 22 ''' trained part of the foreign element 12 ''' against the cavity 33 is pressed. This will cause the cavity of the foreign element 12 ''' compressed and / or compressed, so that the foreign element 12 ''' on the locking element 18 can get over. Subsequently, the cavity will again completely or partially assume its initial shape and thereby the locking portion 22 ''' under the second locking nose 15 the second side edge 6 Press so that the corresponding locking lugs 14 . 15 engage behind. Ultimately, therefore, the required elasticity and / or flexibility of the foreign element 12 ''' as needed instead of by a hinge element 23 '' also by one in the foreign element 12 ''' integrated cavity 33 between the actual locking section 22 ''' and in the groove 11 recorded part 13 of the foreign element 12 ''' to be provided.
  • In the in the 9 represented panel 1'' is between the locking portion 22 ''' and the distal end and the outer end surface, respectively 27 the lower lip 28 the groove 11 a free space 34 available. The open space 34 results from the fact that the angle α between the part received in the groove 13 of the foreign element 12 '' and the locking portion 22 ''' is less than the angle β between the lower edge 35 the groove 11 and the distal end of the lower lip 28 the groove 11 , In the illustrated and so far preferred panel 1'' corresponds to the orientation of the in the groove 11 recorded part 13 of the foreign element 12 '' the orientation of the lower flank 35 the groove 11 , When inserting the foreign element 12 '' in the groove 11 will the out of the groove 11 protruding part of the foreign element 12 '' , In this case, the locking portion 22 ''' , slightly about a pivot axis along the first side edge 1'' to the front, to the second side edge 6 pivoted. The foreign element 12 '' is so far in the groove 11 pushed in until the locking section 22 ''' against the end surface 27 at the distal end of the lower lip 28 the groove 11 pushes and a little further. Therefore, the angle α is between the part received in the groove 13 of the foreign element 12 '' and the locking portion 22 ''' in the unconnected state smaller than in the connected state. The bias voltage of the foreign element thus generated 12 '' is in the connected state of the side edges 5 '' . 6 maintained, because the foreign element 12 '' on the lower lip 28 the groove 11 and at the stop surface 26 of the paragraph 25 on the upper flank of the groove 11 is applied. In the 10 is an alternative embodiment of the panel 1'' according to 9 shown that a similar foreign element 12 ''' like the panel 1'' according to 9 , The first side edge 5 ''' however, in contrast to the first side edge 5 '' according to 9 on the upper flank of the groove 11 no paragraph on which has a pointing into the groove stop surface on which the foreign element 12 ''' can get into contact. The foreign element 12 ''' is preferably frictionally or due to an adhesive cohesively in the groove 11 held. From a positive connection is made in the illustrated and so far preferred panel, although this would also be possible.
  • This in 10 represented and so far preferred foreign element 12 ''' corresponds in its general form as in the 9 shown foreign element 12 ''' , One difference, however, is that in the 10 shown foreign element 12 ''' the required flexibility and / or elasticity for locking the two side edges 5 ''' . 6 even without a cavity can provide. This is achieved by a suitable choice of material and / or by not being in the groove 11 recorded part of the foreign element 12 ''' is formed relatively large volume. Both in the vertical and in the horizontal direction, the corresponding part of the foreign element 12 ''' quite large dimensions. Therefore, even a fairly small length-specific elasticity and / or flexibility of the foreign element is sufficient 12 ''' out to make sure that the foreign element 12 ''' when connecting the two side edges 5 ''' . 6 is sufficiently compressed and / or deflected so that the side edges 5 ''' . 6 can be connected. As the elasticity and / or flexibility by the material and the shape of the locking portion 22 ''' is provided, the locking portion 22 ''' also waiving a hinge element directly with the recorded in the groove part 13 of the foreign element 12 ''' be connected.
  • Due to the fact that the elasticity of a larger area of the foreign element 12 ''' and not, for example, the elasticity of a hinge element 23 '' is exploited, a malfunction can be avoided and ensured that the foreign element 12 ''' after joining the two side edges 5 ''' . 6 with its locking nose 14 the locking nose 15 the second side edge 6 safely engages behind an inadvertent separation of the two side edges 5 ''' . 6 to avoid. This is also supported by the fact that the foreign element 12 ''' between the two side edges 5 ''' . 6 supported on the ground, reflecting the vertical positioning and latching of the foreign element 12 ''' can support, especially if on the panel 1''' the second side edge 6 a weight load.
  • The in the 9 and 10 illustrated locking sections 22 ''' are formed so elastic and / or flexible that the locking portion 22 ''' when connecting the first side edge 5 '' and the second side edge 6 moved in the direction of the panel level and / or compressed. That's where the foreign element comes from 12 '' even without a hinge element. So that the locking section 22 ''' the locking element 18 when connecting makes enough room to pass the locking element 18 to allow, the locking portion 22 ''' in the horizontal direction, which in this case is parallel to the panel plane, be shifted and / or compressed by about 6% to 15% of its original extent in that direction.
