Description

 Panel and method for laying panels

The invention relates generally to panels and methods of laying, with which panels are designed for flat surfaces. In particular, the invention thus relates to panels for producing a floor covering and corresponding

Laying method. In particular, the invention relates to such panels, which are suitable for glueless laying and corresponding installation method.

From the prior art it is known to use similarly formed panels to cover a flat surface. For example, such panels are used for floors. However, such panels can also be used as wall coverings or ceiling panels.

In general, such a panel on a panel body, which is made on the basis of a body. The main body has an upper side and an underside which is generally plane-parallel thereto. Between the top and the

Bottom faces are formed. The end faces generally have profilings which form coupling means and optionally additional locking means. Simple coupling means comprise, for example, a groove and a spring, which are formed on diametrically opposite end faces of the main body or panel body, so that a spring on the end face of a panel can be inserted into a groove in the end face of another similar panel. In such a nested state effect tongue and groove fixation of the panels perpendicular to the top of the panels, which are arranged in a laying plane so that the tops are aligned parallel to each other.

To achieve a decorative effect, the panel body usually on the top of a decor. This can be made in many different ways. Frequently, a printed decorative layer is applied to a main body, which is covered with further synthetic resin and / or lacquer layers in order to protect them in particular from environmental influences and / or to further improve their visual impression. These paint and / or resin layers may also have a

Having surface structuring, for example, in the decorative layer illustrated structures, such as a wood grain or the like, three-dimensional image. Regardless of this possibly existing surface structuring, such a surface is considered to be flat in the further description.

While coupling means such as a groove and a spring can ensure a fixation transversely to the surface of the panels in the installed state, these do not prevent a separation of the interconnected panels in the laying plane. Forces acting parallel to the top of the panels in the laying plane to separate interconnected panels from each other are referred to as so-called pull-out forces.

It is desirable that the panels resist the highest possible pull-out forces in the installed state, without a separation of the panels impinges. In order to achieve a high pull-out strength, locking elements are therefore preferably formed on the end faces of the panels, which interlock in the installed state in such a way that with respect to the separation of the panels in the laying plane a form-locking

Connection is formed between the locking elements. Together, the locking elements together with the coupling elements preferably cause an optimal fixation of the panels to each other both perpendicular to the laying plane and parallel to the laying plane.

Panels are usually formed with a rectangular top and bottom, so that diametrically opposite first end faces and diametrically opposite second end faces, which are formed transversely, generally perpendicular to the first end faces exist. Depending on the length ratio of the first and second end faces, these are referred to as long and short sides. In a two-dimensional installation of panels, it is therefore necessary to achieve high pull-out values both across the long side edges and across the short side edges.

While coupling means in the form of tongue and groove can be formed both on the long sides and on the short sides and are each in each other fügbar while the panels are aligned parallel to each other in the laying plane, this is often not possible with the locking elements. These are often only in one another when the panels to be joined are tilted relative to each other with respect to an axis of rotation, which is aligned parallel to the ends to be joined to each other. In the tilted state, the coupling elements can be inserted into one another and, by means of the parallel alignment of the upper sides of the panels, the locking elements are subsequently brought into engagement, wherein Often one of the coupling and / or locking elements is at least temporarily deformed or deflected, so that a force threshold must be overcome for a subsequent re-Anwinkelung. In such systems, it is usually not possible to achieve a tilt with respect to the long end face and the short end face at the same time for the panels to be joined together. Therefore, different coupling and / or locking elements are often formed on the first end faces and second ends oriented transversely thereto.

In addition to locking systems in which angling and subsequent alignment are necessary when laying, and locking elements are known in which a lowering movement of the end faces transverse to the tops of the panels of the end edges to be joined together is necessary to bring the locking elements with each other. Such locking systems are also referred to as fold-down systems.

Some coupling and locking elements, which are formed on the end faces of panels, have elastically deformable components, which

Into one another and allow locking in a translational movement of the panels to each other in the laying plane. In this case, components of locking elements are elastically deformed during the locking process, which at least partially relax in the locked state and form-fitting

Train connection between the panels.

The aim of the various systems is to achieve adequate fixation of the panels to one another, if possible without a cohesive connection, which could be formed for example by means of adhesives. Further, in some situations it is desirable to resume the laid panels, i. to be able to separate them again without being damaged in order to relocate them in the same or different place.

The systems known from the prior art are either poor

Fixing properties on or can not be separated again without damage. The invention is therefore the technical object of the invention to provide improved panels and an improved method for laying panels, on the one hand ensure easy installation and good fixation of the panels in the installed state and on the other hand allow easy and damage-free disassembly of a laid panel.

The invention is achieved by a panel with the features of claim 1 and a method for laying with the features according to claim 12 and a method for receiving panels according to claim 18. Advantageous embodiments of the invention will become apparent from the dependent claims.

Basic idea of the invention

The invention is based on the basic idea, at least at first diametrically

To provide opposite end faces coupling means and in addition latching elements, the joining and joining of the panels via a

Allow translational movement of the aligned in a plane panels. For this purpose, in addition to the coupling means, which effect a fixation perpendicular to the top of the panels in the nested state, latching elements formed on the diametrically opposite first end faces, which comprise an elastically deformable latching tongue on one of these diametrically opposite first end sides and diametrically opposite on the other first end faces comprise a corresponding notched notch. The elastically deformable latching tongue is in this case formed of a different material than the base body, on the end faces of the coupling elements are arranged. This makes it possible, a sufficient elasticity of the latching tongue with high stability of

Ensuring Paneelgrundkörpers so that a force required during installation to deform the elastically deformable latching tongue until it collapses in the interlocked state in the notch of a panel to be joined, is so low that no impact tools are necessary, their application easily leads to damage of the coupling agent or edges on the front sides.

Preferred embodiments Proposed is a panel comprising a panel body comprising a base body having an upper side and a lower side and end faces between the upper side and the lower side, wherein on diametrically opposite first end faces of the base body coupling means are formed to a similar panel when laying the panel with a similar mechanical engagement of the coupling agent with

Coupling means of the similar panel via a translational movement parallel to the surface of the panel to bring about, in addition to the

Coupling means latching elements are formed, which at one of the diametrically opposite first end faces at least one elastically deformable latching tongue and at the other of the diametrically opposite first end faces a

Include latching notch, wherein the at least one latching tongue is formed of a different material than the main body of the panel. Preferably, the

Main body of the panel made of a wood or wood plastic composite material, a gypsum fiber board, a cement fiber board or similar material, in which via a milling coupling means are formed at least on the diametrically opposite first end faces. As a material for the locking tongue are suitable

in particular plastics or plastic metal composite systems and metals.

Furthermore, a method for laying similar panels is provided, comprising the steps of providing a plurality of panels, arranging one of the panels in a joining plane and arranging another panel in the joining plane such that an upper side of one panel and an upper side of another panel are parallel to each other arranged in a plane and the first facing each other

Have end faces intermeshable coupling agent; Running a

Translational movement in the plane in which the panels are aligned with each other, so that a distance of the panels is reduced and the coupling means of the mutually facing first end faces interlock, wherein during the

Translational movement at least one formed on one of the facing first end faces elastic deformable latching tongue is first deformed and then in a Verrastungskerbe in the other of the first facing each other

Feathered ends and so causes a positive connection between the two panels in the plane.

If it is referred to in connection with the joining of two panels of a joining plane, so this is the laying process in the plane in which the tops the panels to be joined are oriented and aligned parallel to one another. This joining plane during the joining can deviate from the final laying plane, in which many panels are connected to each other flatly.

Such a compound has the advantage that the latching tongue with the

Notching notch causes the panels to be fixed to one another in the plane, preferably the laying plane. Nevertheless, the connection can be easily separated again by the panels are angled relative to a rotation axis parallel to the first end faces against each other. As a result, the latched in the Verrastungskerbe latching tongue is lifted from the Verrastungskerbe, so then a separation of the panels without damage is possible.

Preferably diametrically opposite second end faces are formed transversely to the first end faces, wherein the diametrically opposite second

End faces are complementary to each other and coupling and

Have locking elements, so that the coupling and locking elements of one of the second end faces with the coupling and locking elements of a complementary second end face of a similar further panel are engageable when the panel surfaces are angled relative to a collinear axis of rotation to the second end faces against each other and a subsequent parallel alignment of the tops can be converted into a locked state in which the panels are locked together at their second end faces. In a two-dimensional installation is therefore intended that the first end faces on a

Translational movement of the mutually parallel upper side of the panels is performed and the second end faces are joined together in an angled state to each other and locked together via a subsequent parallel alignment to eliminate the Anwinkelung. Here, the coupling and

Locking elements of the second end faces may be formed with the same effect or identical to the coupling means and Verrastungselementen the first end faces. Thus, both transversely to the first end faces and transversely to the second end faces an optimal fixation in the laying plane is ensured and additionally ensures a fixation perpendicular to the tops of the panels on the interlocking coupling means on the first end faces and on the second end faces. The connection to the second end faces is formed so that they can be easily separated from each other after a renewed angling. If the coupling and locking elements of the second end faces are designed to be identical or identical to the coupling means and latching elements of the first end faces, then it is also possible to arrange the panels in the laying plane or another joining plane and via a translational movement in parallel to the laying or joining plane to merge and clutch and

Lock locking elements together.

In some embodiments, the coupling means, if they are not identical or similar and equivalent to those of the first end faces formed on one of the opposite second end faces a groove and at the diametrically

opposite end face of a spring and the locking elements at one of the two diametrically opposite second end faces at least one

Verriegelungsvorspung and on the other of the diametrically opposite second end faces on a locking recess, which are formed so that in the locked state via the groove and the spring a fixation perpendicular to

Panel top is formed and via a meshing of the at least one locking projection and the at least one locking recess a positive connection in the plane of the parallel aligned panels is effected.

In a preferred development of the laying method, the panels to be joined with their second end faces are attached to a series of already laid panels

angled state relative to the laying plane with the coupling means of the already laid panels engaged. Then the new

to be added panels via a translational movement at the first end faces latched together and then locked by lowering the now interconnected newly added panels in the laying plane with the previously laid panels. This is advantageous both for embodiments in which the second end faces are designed to have the same effect or identical to the first end faces with elastically deformable locking tongues which engage in a Verrastungskerbe in a laid state, as well as for those embodiments in which the second end faces no such have elastic locking tongues and are not suitable for a purely translatory interlocking by means of a translational movement in the laying plane or a joining plane. In the angled state, the panels are on the second end faces not yet locked, so that they can be positioned in parallel to the row of previously laid panels still in a simple manner without much effort. In this case, the first end faces of the panels of the new row of panels, which are each still in the angled position relative to the final laying level, are then also guided into one another and locked.

A recording takes place in accordance with the reverse order, by first the panels are angled about an axis parallel to the second end faces and so separated from the other laid panels and then connected to each other at the first end faces panels via angling with respect to an axis parallel to the first faces are separated.

A method for receiving the laid panels thus provides that one of the panels is deflected on a first end face remote from another of the panels from the laying plane about an axis of rotation which is parallel to the interconnected first end faces of the panels, so that the Tops of the panels are angled against each other and the at least one elastically deformable

Raising tab in the notch is raised or lifted from the notch, and then the panels are removed from each other.

To the force required for the elastic deformation of the latching tongue during the

Keep connection process low and yet to ensure optimum force in the latching tongue in the installed state, is provided in one embodiment that the elastically deformable latching tongue in a relaxed rest position has an angle relative to the top of the panel and a free end of the latching tongue to a center of the panel. This means that the latching element formed over the latching tongue becomes a tip of the end face on which the

Latching tongue is arranged, rejuvenated. Correspondingly, one component of the front side of another panel glides onto the latching tongue when it is joined into one another and deforms it when the first end sides are joined together by a translatory movement parallel to the mutually parallel upper sides. In the spring-loaded state, the free end of the latching tongue faces a support wall of the latching notch and is supported on the pull-out forces occurring therefrom. Since the latching tongue is angled relative to the upper side, at least a part of the acting pull-out forces becomes parallel to one Longitudinal direction of the latching tongue coupled into this. Since a resistance of the latching tongue against a compression of the material is higher than in relation to an elastic deformation transversely to the longitudinal extension, the latching tongue can thus absorb greater pull-out forces than if they were oriented perpendicular to the top.

In order to facilitate a merging of the coupling means and latching elements on the first end faces during installation, a tongue receptacle is formed in the base body to receive the elastically deformed at least one elastically deformable latching tongue until springing into the latching notch of the corresponding first end face of another panel during the laying operation ,

The facing away from the center of a panel support wall of the notch has

Preferably, an inclination that a taper of the notch in

Has compression direction for a latching tongue. This means that the support wall, which faces a free end of the end face, is not oriented perpendicular to the upper side, so that the latching tongue in the latching notch when being guided into each other already bears against the support wall of the notch. The support wall of the latching notch thus prevents complete relaxation of the latching tongue at least until the panels to be joined together are completely joined together. This ensures that even with low manufacturing tolerances or intrusion of foreign components that prevent a complete nesting of the panels, yet a secure locking is guaranteed.

Particularly preferably, the latching tongue is designed as a leg of a locking angle element. An attachment angle of such a locking angle element is arranged in one embodiment on an underside of a spring which is part of the coupling elements. In yet another embodiment, the

Mounting leg of the locking angle element may be arranged on an upper side of a Nutunterwange, which projects relative to the Nutoberwange. Accordingly, the corresponding Verrastungskerben are formed either in an upper side of the projecting Nutunterwange or in the underside of the spring or in the region of a recess which is formed in extension of the underside of the spring for receiving the Nutunterwange. In an alternative embodiment, either at the bottom of the spring or in the top of a projecting Nutunterwange preferably an obliquely to the top extending support notch is incorporated, in which an elastic strip is inserted, the elastically deformable latching tongue with the out of the support notch free end of the strip forms. In such an embodiment, it is easily possible to form the latching tongue so that they along the entire first end face or almost along the entire end face to shorter

End portions, which may be free of the latching tongue extends.

If a locking angle is used, this usually does not extend over the entire length of the first end face. However, such embodiments are also possible. As a rule, however, a plurality of locking angles are fastened to the basic body at regular or irregular intervals. However, the notch generally extends over an entire length of the corresponding first end face. This makes it possible to connect panels at the first end sides with any lateral offset with each other. If no lateral offset between the interconnected panels is desired when laying on the first end faces, then the locking notches can also be formed at the same and uneven intervals corresponding to the fastening positions of corresponding locking angles.

The invention will be explained in more detail with reference to a drawing. Hereby show:

Fig. 7 shows yet another embodiment, which merge into each other first

 Represent side edges of panels.

In Fig. 1 is a plan view of a panel 10 is shown. To recognize a top 1 1. The top 1 1 is usually provided with a decor. This is on a

Basic body usually either imprinted directly a decor or applied to the top of a printed sheet. To protect the decor, the top has one or more resin or varnish layers, which may be corundum to enhance abrasion resistance. The different paint layers can be transparent and clear, transparent and colored or even opaque. In addition, the paint layers can be made either matt or glossy.

In addition, the upper side 1 1 can also have a structuring in order to produce optical and / or haptic effects. Regardless of such structuring, the top 1 1 of the panel 10 is here assumed to be smooth and even.

The panel 10 has diametrically opposed first side edges 20, 30, which in the illustrated embodiment are the short sides of the panel 10. Transverse to the first side edges extend second side edges 40, 50, which are longer than the first side edges. The panel 10 thus has diametrically opposite first side edges 20, 30 and also diametrically opposite second side edges 40, 50. The diametrically opposite first side edges 20, 30 have mutually complementary coupling means, which are formed, for example, as a spring 25 and groove 35. At the first side edge 20, the spring 25 can be seen, at the opposite first side edge 30 is looking at a projection 36 of a Nutunterwange 37. In this embodiment, in the Nutunterwange 37 additionally as a Verrastungselement 70 a Verrastungskerbe 60 is formed, whose function continues is described below. At the second side edges 40, 50 are also

Coupling formed. At the one second side edge 40, a spring 45 can be seen in the embodiment shown. At the diametrically opposite second side edge 50 is facing a projection 56 of a Nutunterwange 57 a groove 55. On the Nutunterwange 57 can be seen on the opposite second side edge 50, a locking projection 90. This preferably extends over the entire length of the opposite second side edge 50. In an alternative embodiment, at the second side edges 40, 50 coupling means and

Locking means are formed, which are the same effect or identical to the coupling means and latching elements formed on the opposite first side edges 20, 30.

In Fig. 2a, a first end face 20 of a panel 10 and an opposite first side edge 30 'of another panel 10' are shown schematically. Same technical features are identified in the various embodiments with the same reference numerals. Superscript dashes such as "',", "'" etc. are used to distinguish features on different panels, ie the number of dashes is an assignment to the corresponding panel All features that have no or the same number of superscript dashes belong to the same panel or panel group.

In Fig. 2a, the process of joining the panels 10, 10 'via a translational movement parallel to the tops 11, 11' of the panels 10, 10 ', as indicated by a translatory arrow 101. At the first side edge 20 of the panel 10, a spring 25 is formed. At the bottom or an adjacent

Unterwangenaufnahmeaussparung 26 a support groove 27 is formed. In this holding notch 27, as an engaging element 70, an at least partially elastically deformable element in the form of an elastic strip 71 is fastened. A part 72 of the strip 71 projecting from the retaining notch 27 forms an elastically deformable latching tongue 73. In this embodiment, a tongue receptacle 28 is formed in the underside of the spring 25 or in the region of the lower cheek-receiving recess 26. In this is the elastically deformable latching tongue 73 during the

Connecting the panels 10, 10 'added. This is due to the fact that an outer edge 38 'of the projecting Nutunterwange 37' upon assembly of the panels 10, 10 'presses against the latching tongue 73. This is elastically deformed and penetrates into the tongue receptacle 28. 2b shows the state in which the panels 10, 10 'are completely guided into one another with the coupling means 24, 34, ie the spring 25 has completely penetrated into the groove 35. Further, the latching tongue 73 is in the Verrastungskerbe 60 of

Nutunterwange 37 springs. In this embodiment, the latching tongue 73 and the Verrastungskerbe 60, the latching elements 70. If an attempt is made, the panels 10, 10 'parallel to their surfaces 1 1, 1 1' to separate from each other, so pushes a free end 29 of the latching tongue 73 against a Supporting wall 61 of the latching notch 60 '. The support wall 61 'is inclined relative to the upper side of the panel or an upper side of the groove lower side, so that the latching notch 60' tapers in the springing direction 62, which is indicated by an arrow. This ensures that the free end 29 of the locking tongue 73 abuts against the support wall 61 'of the Verrastungskerbe 60' and is supported on this, even if the spring 25 is not fully penetrated into the groove 35 '.

Preferably, the further notch 65 'has an inclination which approximately corresponds to the inclination of the detent tongue 73 in the relaxed state. This is inclined relative to the top 1 1 of the panel 10 and the bottom 12 of the panel 10 so that the free end 29 faces a center 15 of the panel. The latching element 70 in the form of the latching tongue 73 thus tapers to a tip 22 of a first

Side edge 20. This ensures that a deflection of the elastic latching tongue is made easier when joining together and on the other hand, a part of the pull-out forces which are transmitted via the support wall 61 'on the latching tongue 73 in one

Act longitudinal direction 1 10 and thus leads to a compression of the material of the latching tongue. Such material compression usually requires greater forces than an elastic deflection transversely to the longitudinal direction 1 10 of the latching tongue 73. To their

To prevent deflection, the further notch wall 65 'is inclined so that it is parallel to the latching tongue 73 in the relaxed or almost relaxed state, so that upon deflection of the latching tongue 73 against the further notch 65' the further notch 65 'prevents this deflection.

In Fig. 2c is shown that an angle of the panels 10, 10 'about an axis of rotation 120 which is perpendicular to the plane of the drawing and parallel to the first side edges 20, 30' results in that the latching tongue 73 from the

Latching notch 60 'is lifted. After that, it's just possible to work with each other connected first side edges 20, 30 'of the panels 10, 10' again separated from each other.

FIGS. 3a to 3c show the corresponding situations when joining and separating panels 10, 10 'at their first side edges 20, 30' for another embodiment of the locking elements 70 '. In this embodiment, as a latching element 70 ', the elastically deformable latching tongue 73' as a leg of a locking angle 130 'is formed. An attachment leg is arranged in a recess, which is also referred to as a Rastwinkelaufnahme 39 '. This is formed so deep that it can in addition to the mounting leg 131 'and the second leg 132' of the Verrastungselements 70 ', which is the latching tongue 73', with record. The locking angle receptacle 39 'thus also additionally constitutes a latching tongue receptacle 28'. In this embodiment, the latching tongue 73 ', when the panel 10 is translationally joined to the panel 10', is replaced by the tip 22 of the first side edge 20, i. deflected and deformed by an edge of the spring 25. If the spring 25 has penetrated into the groove 35 ', the elastically deformed latching tongue 73' springs into the latching notch 60, which in this case is formed in the lower side of the spring 25 or in the region of a lower beam receiving recess 26. In this embodiment too, the latching notch 60 constitutes a latching element 70. Again, the support wall 61 preferably again has an inclination which leads to a tapering of the latching notch 60 in the springing direction 62. The further detent notch 65 is formed again with an inclination, which causes this wall in the latched state as possible parallel to the then largely relaxed or completely relaxed detent tongue 73 'is formed. The latched state is shown in Fig. 3b.

In Fig. 3c it can be seen again that angling of the panels 10, 10 'about an axis of rotation 120, which is parallel to the short end faces 20, 30' and perpendicular to the plane, leads to the latching tongue 73 'from of the

Lock notch 60 is lifted and a separation of the panels 10, 10 'is easily possible. Since only an elastic deformation of the latching tongue 73 'is necessary to bring about the latching connection, no forces needing to be overcome which require the use of impact tools or the like. Thus, damage is caused by

End faces 20, 30 'and 30, 20' (not shown), which upon impact of

Coupling agents often occur in coupling means of another panel avoided. In Fig. 4 is a cross-section through a panel 10 and another panel 10 "shown schematically, in which case the connection of the second side edges 40, 50 'to a

Embodiment is shown, in which the coupling means are not formed gleichwirkend or identical to the first side edges. In addition to the coupling means 44, 54 in the form of a spring 45 and a groove 55 ', the panel 10 has a

Locking recess 91 and the other panel 10 "at the top of

Nutunterwange 57 a corresponding locking projection 90 'on. In the laying position, the locking projection 90 'engages in the locking recess 91 and thus results in a positive connection between the panel 10 and the other panel 10' with respect to pull-out forces parallel to the laying plane, i. parallel to the tops 1 1, 1 1 'of the panels 10, 10'. Depending on the specific embodiment, a tension-free or voltage-locking can be performed. In the case of a voltage-locking lock, the locking projection 90 'is slightly deformed or deflected in the installed state. The corresponding forces are supported on abutting edges 42, 52 'of the second end faces 40, 50'.

The laying of panels 10, 10 ', 10 "shall be explained with reference to FIG. 5, which at the first side edges 20, 30, 20", 30' via an elastically deformable latching tongue in cooperation with a Verrastungskerbe 60 "and the second End faces 40, 50, 40 ', 40 "are interconnected via locking elements, which are in an angled state of the panels 10, 10', 10" in one another fügbar and lock in a parallel alignment of the panels 10, 10 ', 10 "to each other, as shown in Fig. 4.

In the situation which is shown in the upper area of FIG. 5, two rows of panels 10 have already been laid. Two further panels 10 'and 10 "are angled with their second side edges 40', 40" opposite the already laid panels 10 about an axis of rotation which is parallel to the second end faces 50, 40 ', 40 "and with their coupling means 44 ', 44 ", 54 nested (step 1), here for example with their springs 45', 45", introduced into the corresponding grooves 55 of the already laid panels 10, as shown in the provided with the letter A cross-sectional view bottom left ,

Before the panels 10 'and 10 "are lowered relative to the previously laid panels 10, the first end faces 20", 30' are moved over one Translational movement so that the panels 10 'and 10 ", with their top sides 11', 11 'aligned in parallel, engage with each other (step 2), which is schematically illustrated in two partial steps in the middle of FIG

Cross-sectional views B and C indicated. The latching tongue 73 'engages in the latching notch 60 "of the panel 10 and latched therein.

In a third step (step 3), the panels 10 and 10 'thus joined are aligned with the previously laid panels, i. lowered. This is indicated at the bottom right under the cross-sectional view D marked with the letter D and leads to a locking of the second end faces 50, 40 ', 40 "both transversely to the first end faces 20, 30, 20", 30' and across the second

Stirnseiten40, 50, 40 ', 40 "has entered such a locking or locking, so that the panels in both directions transverse to the respective end faces have high pull-out values.

Nevertheless, such a laid floor can be easily resumed and the panels 10, 10 ', 10 "separated from each other by performing the steps shown in Fig. 5 in reverse order, with the step shown in letters B and C. is undone by the fact that the panels 10 and 10 "with respect to the first side edges 20", 30 'are angled against each other, so that the latching tongue 73' from the latching recess 60 "is lifted and the panels 10 ', 10" can be easily separated.

The laying of the panels can also be used in embodiments in which the second side edges are formed with coupling and locking means, which are identical or identical to the coupling means and latching elements at the first side edges, analogous to that described in connection with FIG

Approach done. As is apparent from Fig. 2c and 3c, panels whose coupling means may comprise an elastic element in the form of a latching tongue, which consists of a different material than the main body of the panel, as this is described for the first side edges, not only via a translational movement analogous Fig. 2a and 2b or analogous to Fig. 3a and 3b are interconnected. Rather, it is also possible the panels in an angled position to merge into each other, in which they could also be separated again, as shown in Fig. 2c and 3c. If you lower the panels, ie bring the tops of the panels in a plane, the coupling elements lock the panels, as shown in Fig. 2b and 3b. The joining of the panels can therefore be analogous to that in the

Connection with Fig. 5 described procedure, even if the first and second side edges are formed similar. In these embodiments, however, it is additionally possible, the second side edges alternatively via a

Translational movement to connect while the tops of the panels are aligned parallel to each other. When laying, these embodiments with similar first and second side edges offer greater flexibility.

Picking up also takes place for this embodiment, in which the first and second side edges have an elastic element in the form of a deformable latching tongue, which is made of a different material than the basic body of the panel, in such a way that two rows of panels against each other about an axis parallel to the second side edge (cf. analogous to FIG. 5), so that the latching tongues are lifted out of the latching notches, as is indicated by way of example in FIG. 2c or 3c. So the rows of panels are gradually separated. Within the rows, the panels are separated from each other in the same way by angling. This is possible non-destructively.

In Figs. 6 and 7, embodiments similar to Figs. 2 and 3 are shown. These differ from the previously shown embodiments in that, for example, in the embodiment of FIG. 6, the retaining notch 27 'is formed in the Nutunterwange and the corresponding notch 60 in the underside of the spring or the Nutunterwangenaufnahmeaussparung. Accordingly, in Fig. 7, the locking angle 130 ', on which the latching tongue 73' is formed, in one

Rastwinkelaufnahme 39 'at the bottom of the spring 25' and the

Nutunterwangenaufnahmeaussparung 26 'formed. Accordingly, the

Locking notch 60 is formed in the Nutunterwange 37 in this embodiment.

The described embodiments have the advantage that, on the one hand, they permit easy laying, which can be carried out by one person. In addition, it is ensured that the panels can be separated again from each other without damage and thus a reusability is ensured. This is particularly advantageous for high-quality floors, which have a lacquered top and which are used, for example, in exhibition stands, of particular advantage can be reused several times and no damage to the corresponding edges of the top occur.
