Abstract

The invention relates to components for the production of a covering, in particular for a floor. The components comprise panels (1, 2, 2a) which have coupling elements (3,12, 6, 14) embodied such that two panels (1, 2, 2a) can be joined perpendicular to the common joint (11) and simultaneously parallel to the surface (9) as well as perpendicular to the common surfaces (9) by means of a positive fit. A cord- or rod-like element (18, 22, 32) is arranged between the panels (1, 2, 2a) in a recess (11, 23) and is preferably introduced between the panels by means of a laying aid. Particularly large rooms can be provided with said covering. Novel optical effects can also be achieved when said cord- or rod-like element (18, 22, 32) is visible on the surface (9). The joint (11) also achieves a particularly good protection against moisture and dust.

Description

Panels with border besides laying aid

The invention relates to components for providing a covering. The components comprise in particular a panel, which can be positively connected to a second panel, so that a

both present locking perpendicular to the common surface as well as perpendicular to the common connecting joint and at the same time parallel to the common surface, can then be dispensed with the use of glue, when the panels according to the invention as a covering for a floor, or a

Wall paneling are used,

A panel of the aforementioned type is or, for example, from the publication US 6,324, 803 Bl, EP 0 698 1 62 Bl known, the known panel is connected to a second means of a tongue and groove

Compound positively locked perpendicular to the common surface of the panel, the groove comprises an upper and a lower flank. The lower edge is longer than the top and has a projecting locking element at the end. In the connected state, the protruding locking element engages in a recess, which is placed below the adjacent panel, this way a positive lock is achieved which acts parallel to the common surface of the two panels and at the same time perpendicular to the common joint of the two panels,

In the locked state of two panels remains between the projecting locking element and the recess a game, so that, among other things, a panel can be easily moved relative to the other along the common connecting joint, the transition from the preceding edge of the locking element extends perpendicularly, that the locking element projects vertically in the height of the recess below the adjacent panel has walls that are perpendicular to the common surface of the panels. It pushes or a vertically extending wall, the contact surface of the recess on a vertically extending wall or contact surface of the projecting locking element in the locked state, This ensures that the panels can not accidentally be able to solve in the installed state with a greater force of one another,

The game is further required in spite of the aforementioned vertical walls to be able to connect two panels, for example, by a rotary movement about the common connecting joint around. In the aforementioned document it is stated that a clearance of 0 mm 2/1 may be present,

The material from which the panels of the aforementioned type can be made, is in principle freely selectable, but in particular panels according to the invention are concerned, which consists wholly or predominantly of wood material. At a

Parkettpaneel this can be completely made of wood. Alternatively, a Parkettpaneel may comprise a support plate, which for example consists of HDF or MDF, above the carrier plate, one or more floor slats are applied. Below the carrier plate a layer, or a paper may be applied to cause a turn in order to avoid deformations. There are further provided without glue interconnectable panels known which consist wholly or mainly of plastic material, for example from the publication US 04426820,

The invention further relates in particular to a laminate floor. This comprises a support plate made of a wooden material. As wood material HDF and MDF are presently preferred, Another typical wood material consists of glue-coated chips, above the support plate a decorative layer is applied which comprises a decorative paper together with a protective layer The protective layer consists in particular of a resin which, among other abrasion resistant particles such as corundum or SiC has, underneath the support plate, a counteracting paper is applied in order to prevent the aforementioned deformations,

Currently, there are indications that technical laminates to

will gain importance and from this increasingly panels are made, these are used in particular as floor covering,

Resin Impregnated papers are fed in the preparation together with the carrier plate of a press, with supply of heat and pressure, the papers with the carrier plate are glued, this case already has the decorative paper layer with the abrasion resistant particles on,

Panels of the kind according to the invention may comprise one or more of the aforementioned features.

By the experts, the aforementioned game was felt to be too disadvantageous because is able to penetrate into this dust and moisture. Visually the game is perceived as a negative, as can occur at the surface of a gap.

To avoid such a game is, for example, from the publication EP 0843763 Bl, a panel is known in which obliquely extending contact surfaces are provided in place of the aforementioned vertical contact surfaces, the ramps are such that two panels, for example, by a rotary movement about a common connecting joint around can be joined together without dαss a gap remains on the surface of the two panels due to a game. From this document is also known to design the protruding lower lip elastically so as to allow bonding by displacement in one plane,

Although in the above-mentioned prior art, the perceived as disadvantageous game is avoided in the common connecting joint, but then, however, the move requires a panel, which is connected to a second

Example is connected via longitudinal sides along the common connecting joint a large force. In general, the force is so great that this tool like a hammer and tapping block must be used. While damage to the panels may occur.

or due to the inclined contact surfaces, and the elastic lip edge of a groove can be connected to each other panels not only by moving within a plane, but can also be released again in this manner, undesirable can also solve two already installed panels with appropriate force from one another again, this problem occurs in particular when two equally long lips are provided, and the locking member, which causes the locking parallel to the floor surface and perpendicular to the connecting joint, located within the groove, then this is in fact very small to design, since little space is available, such as the utility model DE 29823749 UI can be seen,

provide two equally long lips has advantages over the prior art with the long protruding lip on the following benefits, the one hand, saves material in the manufacture as compared to a prior art in which an edge or lip to the other of a groove protrudes, on the other hand, the spring reaches into the groove very reliable, Moreover, the consumer is very familiar with a tongue and groove system in which the sides are of equal length.

The object of the invention is the provision of components for providing a covering, in particular a panel of the type mentioned, can in which the advantages of a panel can be obtained which can be connected to a second panel with play, without disadvantageous in the laid state dust and moisture can penetrate into the joint undesirable. The object of the invention is the creation of an installation aid for the novel components or panels, as well as the specification of an installation process.

The object of the invention is a component, in particular a

Panel solved with the features of the first claim and by a laying aid and a method according to the independent claims, advantageous embodiments result from the dependent claims,

According to the invention there is between two glueless interlocked panels, a recess in which is located in the finally installed state of a lace-or rod-like element, which in particular consists of a compressible material, as a flexible material such as Teflon may be provided, however, to be preferred is a material which has good elastic properties, the lace-up or therefore the rod-like element consists for example of a rubber, silicone, however, is preferable to the rubber, because silicone has a suitably higher Rückstellkrαft compared to rubber, higher compared to rubber restoring force of silicone has proven to be advantageous

The provision of a gap or recess between two

Panels allows for easier displacement of a panel along a common connecting joint, even if no play between two panels should be available. The presence of a game is to be preferred in order to ensure easy sliding. It is sufficient for this

End, a game of a few 1/1 00 millimeters.

The aforementioned gap or recess occurs in particular on the surface of two panels which forms the visible part of a floor or wall covering. From the surface, the lace-or rod-like element is visible in the locked state, the lace-or rod-like member, in particular such that this completely fills the width of the gap, Advantageously, the lace-or rod-like member slightly wider, it is then in the compressed state within the gap,

or by providing a gap, a recess between the panels, in which a lace-or rod-like member is located, the friction is in particular in comparison with those

Panels lowered, in which the locking elements are integrally connected to the panel and made of a wood material, according to the invention can be, for example, integrally provided with the panel connected panels so that consist of a wood material and the still relatively easy and then shifted along a common connecting joint can be, when two panels are interlocked with each other, the gap therebetween with the lace-or rod-like element on the visible surface so as to further open as a side effect of new design possibilities, in the joint area black rubber or Siiikonmaterial is visible for example, the surface of the panel may have a strong contrast to this, moreover, there arise such new optical effects that are not known, in particular for laminate panels, a discreet appearance is desired, then, the lace-or rod-like member, as far as this is visible, f arblich adapted to the visible surface, While there are also designs that have a colored border or color edges on the surface of each panel, in contrast, the customer can choose the color of the border freely and modify later, so it is possible to vary the appearance of already installed panels with a relatively small effort, without having to remove the flooring. So the provided on the surface by two adjacent panels recess offers the technical advantage of the lighter displacement, the ability to easily modify visual impressions,

The lace-or rod-like member may or from the surface later in the gap, are pressed in the recess or inserted, but it may also be already connected to a panel, especially if the lace-up or is rod-like member made of a compressible material. Subsequent insertion of a separate rod-like or lace-

However element into a gap offers the advantage that the panels can be very easily moved as long as the lace-or rod-like element is not inserted,

Is a match between a protruding locking member and a corresponding recess is present, vertical or undercut contact surfaces can be provided. The lace-up or rod-like element is then compressed slightly when connecting if it was delivered at the factory connected to a panel. Despite the vertical contact surfaces as possible bonding, for example, by turning about a common connecting joint around.

It is even possible undercuts in the above

provide locking element and the recess. Are interconnected panels pressed apart parallel to the floor surface, so hooked then with correspondingly arranged locking element and correspondingly arranged recess, the aforementioned contact surfaces into each other, a non-destructive release of the locking or, coupling elements by displacement in a plane perpendicular to the connecting joint is not possible, which in the prior technique called unwanted loosening due to accidental application of force is even avoided if, for example, a, for example, projecting flank of a groove is configured elastically with a locking element at the end, reference therefore in spite of a resilient lip of a groove, a particularly reliable locking parallel to the floor surface and perpendicular to a common connecting joint to be created such as pads are to be preferred, the undercut or are arranged at least perpendicular to the surface,

Extending the contact surfaces in the above-mentioned type obliquely, as is known from the publication EP 0843763 B l, it is a rigid configuration of a protruding lower edge or lip of a groove to be preferred, so as to provide reliable locking parallel and perpendicular to a common connecting joint provide If a particularly reliable connection between the laid panels is desired, the projecting lip is designed rigidly and in perpendicular contact surfaces, so that loosening by displacement in a plane perpendicular to the connecting joint is not possible. The other Kuppiungselemente are then, if necessary, rigidly formed, is affected by this example, a spring that causes a groove a locking perpendicular to the common surface of the panels,

If panels are initially locked together, then a match exists and is provided only then the lace-or rod-like member from above or in a occurring gap to bring the recess, so a particularly simple displacement along a connecting joint with almost no force is possible, the possibility of shifting already interlocked panels along a common connecting joint is particularly desirable when two longitudinal sides of two panels are already connected and is now narrow sides are still to be connected, such a method is known for example from EP

0855482 B l known. Specifically, when the bonding requires regularly to be able to move the panels along a common connecting joint despite already locked state, the embodiment is advantageous in which a cord or rod-like member from above last is put into a gap or pressed.

The lace-like member or rod typically has a diameter or a width of at least 0.5 mm, preferably of at least 1 mm, more preferably of at least 2 mm. The width does not exceed 1 regularly 0 mm, unless a greater width is desired for optical reasons. Preferably, the width is less than 5 mm, more preferably less than 3mm. Basically, however, smaller or larger widths or diameters may be provided, for example for optical reasons.

The gap, in which the lace-up or is rod-like member, normally has a slightly smaller width than the lace-up or stαbαrtige element, particularly if a match offset or ingress of dust and moisture in a connecting joint should be avoided. The lace-or rod-like member is then lightly pressed in the gap and is held in the gap, but the gap may also have the same

having width, only a greater width of the nip in comparison to the width of the lace-or rod-like member and the diameter should be avoided since otherwise an undesirable gap remains on the surface and the lace-up or load easily detach rod-like member to when this has been inserted from the surface, an interference fit of the lace-or rod-like member in the gap is preferable since then the gap-free state is ensured and the cord or bar-like element is held,

In one embodiment of the invention is the cord or bar-like element in the locked state between two surfaces, which cause locking. For example, this may be the areas that are mentioned here contact surfaces. The cord then in particular consists of an elastic material such as rubber or silicone. Before two panels are locked, the lace-up is to apply or rod-like member to one of the above latched surfaces. The lace-or rod-like member is then in particular partially in a recess and is fully depressed in this further or even if panels are locked together. For example, a panel is latched by a rotational movement or a lowering movement, which is known for example from document DE 20008708 UI in a second case, the lace-up or is pushed rod-like element into the recess due to the

Presence of a game that a panel can now be pushed further in the direction of the other panel. Characterized the depression is released, the lace-or rod-like member relaxes and so passes between the two (contact) surfaces which bring about a latch.

For example, if a protruding edge provided which merges at the end by a right angle in a locking element, so there is the aforementioned recess preferably immediately before the transition to the locking element. In this recess the lace-or rod-like member is inserted or already fitted in the factory here been so vulcanized, for example.

In the aforementioned embodiment, it may be expedient that remain even in the relaxed state of the lace-or rod-like member, a gap or a recess on the surface. a second lace-or rod-like member is then introduced into this gap. Alternatively, already already a cord or rod-like member to be mounted of compressible material on the surface at an abutting edge of a panel, this may be advantageous in order to achieve the aforementioned design effects or voltages compensate that are virtually impossible to avoid in particular at a wood material .

A first and provided a second lace-or rod-like member at a connecting joint between two panels, so here opened further the advantage that the panels rather may initially at the surface by means of an appropriate tool will be pressed apart, is so created space, around here to bring an lace-or rod-like element easily. If the lace-or rod-like member substantially inserted, the tool is removed. The lace-or rod-like member, which is located between two locking contact surfaces, then relaxes in such a manner that no gap remains on the surface. There is provided a lace-up or stαbαrtiges element in the interior of the connecting joint between two Kontαktflächen which effect a locking, this allows an embodiment to be connected at the two panels by

Coupling elements of a panel are first brought by a vertical movement relative to the subsequent joint surface of two panels in the coupling elements of a second panel, In this case, the lace-or rod-like member can be pressed, for example, in a corresponding recess,

Subsequently, the panels are fed successively pushed. In a corresponding configuration at this succession sliding over a spring may enter a groove and effect a locking perpendicular to the common surface. The aforementioned lace-or rod-like member eventually relaxes and passes between the two locking contact surfaces,

However, the lace-or rod-like member may have a circular or triangular diameter, it is of the

Surface forth recently introduced, so it may be advantageous that the lace-or rod-like member at two opposite sides is designed hook-shaped If the lace-up or pressed rod-like element corresponding to a gap from above, these hook act like barbs. If the lace-up or pressed rod-like member in the gap, the visible surface of the lace-or rod-like member may be surface configured so as to provide a planar degree with the remaining surface of the panels.

Opposite to the surface of the lace-or rod-like member, which is visible from the surface, for example a curved recess can be provided so that can be obliquely projecting hook press into the gap better. In the embodiment with the hook and the arched bottom recess, a press fit is advantageous to realize,

The lace-or rod-like member advantageously comprises a

Thread, which can practically not be stretched, the thread is then generally enveloped by a compressible material, it is ensured that the lace-or rod-like, consisting of a compressible material element or by pressing in in a gap, not disadvantageous in a recess is stretched, which would lace-or rod-like member initially stretched, it will contract again in the laid state, it would be undesirable areas or in the recesses, gaps occur which are not filled with a cord-like or rod-like member,

To particularly easy to lay, at least two opposing sides of a panel have such locking elements, in which a bonding is possible by using a panel is first lowered vertically against the other, the one panel is arranged in parallel relative to the second, are particular equipped with such locking members in such a case, the narrow sides, when the surface of a panel is rectangular. The long sides are then preferably designed so that a connecting in of the

Typically, a rotational movement about a connecting joint around requires If a panel on the long side joined by a rotational movement at the longitudinal side of a second panel, a narrow side can at the same time or in the corresponding lock, enter Kupplungselemenf an already laid panel, it is likewise the narrow side of the already laid panel. Then, it can, depending on the embodiment may be necessary, the panels which are connected to each other via the narrow sides, blaming each other slightly. Typically, this last move can be limited to a few tenth of a millimeter. In this way, the displacement in the final position is compared to the initially

The prior art mentioned 5 kept very low. Accordingly, the time required for the installation can be reduced. Also it should be noted that a method for the laying of the panels comprising a displacement, u, a, then is especially undesirable when a panel of an initially close to

0 wall is. A tool can then hardly between the

Panel and the wall are brought to perform the shifting of a tool. Particularly undesirable displacement may then be further, when a small projection, for example, due to a door frame is present in a room,

5 to which a panel is to be adjacent tight, then it is particularly advantageous to be able to connect to each other by a lowering movement of the panels, the narrow sides can be constituted, for example, in the UI 20,008,708 known from the publication DE manner, insofar as the therefrom

-0 known coupling elements connecting by lowering relate,

The lace-or rod-like member may have a substantially rectangular or square diameter to? 5 to be able to effect a two-dimensional degree at the surface,

A lace-up or rod-like member according to the invention has the desired elasticity, or flexibility, or if the width, the diameter can be reduced by compressing 30 may, metallic solid material or timber is not compressible.

The claimed dimensions of the panels are advantageous because they can be easily handled. In particular, dimensions below 1 00 cm are advantageous since the panels can be easily transported even in the trunk of sedans,

If two rod- or cord-like elements are provided, these are preferably arranged so that the restoring forces which occur due to the rod- or cord-like elements are such that no gap remains on the surface. It is therefore advantageous that a rod- or cord-like element which is adjacent to the visible surface of the panels, relatively low restoring forces can cause. Panels are so far apart not undesirably pressed. The restoring forces by the choice of materials from which the rod or cord-like

consist member can be suitably adjusted, In addition or alternatively, the cross-sections can be appropriately selected, therefore, the surface-adjoining rod- or cord-like member preferably has a larger area in cross section than the other, the rod- or cord-like member,

In a further embodiment, a lace-or rod-shaped element effects a locking of two panels in one of said directions, that, for example, perpendicular to the common surface of the panels, in particular two panels are parallel and at the same time locked together perpendicular to the common connecting joint when the rod-shaped or cord-like element is pushed into a corresponding recess,

The embodiment in which the pushing a rod or cord-like element causes a locking of two panels, in turn, enables the presence of vertical or undercut contact surfaces. So manage a connection that is maintained even when not intended force. In order to obtain vertical contact surfaces to obtain a lock, for example, parallel to the surface and at the same time perpendicular to the common joint of two panels, the lace-or rod-shaped element in the simplest case a rectangular cross section. The coupling elements of the two panels to be connected include recesses, which also has a rectangular

have cross-section. Are the two panels joined together, for example by moving in a plane, so finally an end position yet, at the border, the two aforementioned recesses with rectangular cross-sections to each other, then forming a channel with a rectangular cross section, In this channel then the pushed lace-or rod-shaped element, is the lace-or rod-shaped element sufficiently wide and sufficiently high, the two panels are interlocked without the backlash occurs. The contact surfaces which cause the positive locking, are perpendicular.

the art, in which a connection on the basis of a tongue and groove connection is made, a resilient lip or edge are provided together with other locking elements, so as to allow a positive connection by displacement in a plane when said state, damage may in particular occur when the material is relatively rigid. This is particularly the case when the coupling elements, so are made of a wood material, for example made of MDF or HDF,

This easily possible damage to the coupling elements can be avoided in the aforementioned embodiment. The compound can be mechanically very stable since vertical or undercut contact surfaces can be provided, even with oblique contact surfaces, as they exit the

EP 00843763 B l are known, a stable mechanical connection can be made possible, since an elastic flank is not necessary and the locking member may protrude relatively far, a projecting edge in the 00843763 Bl known from the document EP manner provided, this can be relatively short, since it is not deflected downward when connecting, it is saved according to material so that there is a definite cost advantage,

In the prior art, such as these, from the document DE 29823749 is known UI, two equally long edges are proposed, a serving of the locking recess is located inside the groove, a corresponding protruding locking element is located at a suitable position on the spring of a second panel, for reasons of space and production reasons the locking element is only slightly protrudes and has an inclined path, Accordingly, the recess is formed inside the groove and dimensioned the resulting form-fitting connection is parallel to the floor surface and also perpendicular to the connecting joint mechanically relatively unstable, the instability is in the present embodiment, the guide form, for example, by vertical or relatively steep contact surfaces when an embodiment with equally long edges of a groove acting as a coupling element is provided avoided.

To reach undercut contact surfaces in the embodiment in which the pushing a rod or cord-like element causes a locking of two panels,,, the rod- or cord-like element in cross section, for example, a constriction on. Recesses in the coupling elements, in which the rod- or cord-like

Element is pushed for the purpose of locking, conveniently have a corresponding thereto cross section. To be able to push the rod- or cord-like element in recesses in the coupling elements, so as to lock two panels together, the rod- or cord-like member preferably has a smooth surface to keep occurring during the Into pushing sliding friction low, the rod-shaped or cord-like element then consists in particular of non- or slightly compressible material in order to also avoid a gap at the surface of the panels, if no additional rod- or cord-like element to be incorporated on the surface, as material for the rod- or cord-like element or its surface may therefore be expedient Teflon, HDF, MDF also have relatively smooth surfaces and therefore can be preferably used also, also, a bar of metal or with a metallic surface has a smooth surface and therefore can be preferably used,

Around the rod- or cord-like thread element in recesses in the coupling elements and to be able to push, tapers the rod- or cord-like member advantageously at least one end,

the embodiment in which the pushing a rod or schhurförmigen element causes a locking of two panels, is provided on narrow sides of panels, which have a rectangular surface, the panels are then joined at the longitudinal sides, in particular by a rotary movement to each other, where necessary is preferable narrow sides of already laid panels are then fed pushed each other. Finally, the rod- or cord-like member is slid on the corresponding short side. Narrow sides between which the rod- or cord-like element is pushed for the purpose of locking are preferable, since the distance is relatively short, that is correspondingly short rod- or cord-like element in push to lock corresponding to two panels.

The embodiment in which the pushing a rod or cord-like element causes a locking of two panels, can be combined with a panel with the processes known from the prior art coupling elements for providing a glueless connection. Particularly preferable is a panel having for example a rectangular surface, which is preferably arranged on the longitudinal side so that it can be connected without glue by means of a rotational movement to a second panel, so that no play between the panels remains. Such an embodiment is 01/48332 is known from document WO particular, this embodiment comprises a rigid protruding lower lip or edge, in order to achieve a mechanically stable connection. the embodiment is on another side of the panel, ie in particular at the narrow side then is provided wherein the pushing a rod or cord-like element causes a locking of two panels, First, a first and a second

Panel by means of the rotary motion connected to one another, then the second panel along the common connecting joint to a neighboring, already connected to the first panel panel is supplied delayed. Finally, the second and third panel is definitively connected to each other by the rod or cord-like element is pushed into a channel which is formed by recesses in the corresponding coupling members.

According to the invention, it may be a parquet or

Laminate panel or the like. It can be square or oblong. It can be wood, a wood material such as MDF or HDF, stone, plastic, clay, ceramic, metal, etc. are made. It is therefore possible by the invention to move even one made of stone floor swimming.

A method for the laying of the covering elements or panels comprising the steps of,

A first panel already laid, it has laterally lower projecting edges In the above edge is a groove-shaped recess, Either in this recess or in a groove within the recess a line (or rod), which can be deformed radially elastically , inlaid, the cord or the rod preferably consists of a chord of a material having low elastic properties, which is so encased by a resilient material such as rubber,

Due to the tendon, the cord (the bar) does not change its length. A second panel is applied to one side, and that preferably the longitudinal side to the first example, an angle and connected by pivoting in the common panel plane with the already laid panel in such a way that these are connected in parallel to the common surface as well as perpendicular to each other to the common joint by positive locking , Depending on

Embodiment can be carried out also by lowering the joining one panel to the other.

A second panel is installed to the longitudinal edge of the first

applied panel obliquely and connected by pivoting or lowering with this in the aforementioned manner,

The other sites and as a rule the narrow sides of

Panels are arranged so that locking elements grip behind each other when the is lowered one panel relative to the other panels With an appropriate positioning of the two latter are in the lowered position already a latch the two panels parallel to the common surface as well as perpendicular to the common connecting joint locked together. Subsequently, the two are finally supplied inserted said successive panels, this case reaches a spring of one panel into the groove of another panel, the two panels are thus vertical to the

Floor level connected, necessary, be shifted the two panels last laid in the direction of the already laid panel, whereby a classical tongue and groove connection is brought about by the classical tongue and groove connection, the two panels are vertically locked to the common surface by a form fit with one another ,

The protruding lip on the narrow side also has a groove already described above. In the pushed-together

State of the two panels the rod- or cord-like element, for example in the form of a round rubber into the channel may be pushed, which is formed by the aforementioned groove and the panel latter. The dimensions are chosen in particular so that between the round rubber and the aforementioned channel remains a game. The sliding the rod or cord-like element then takes place particularly easy.

It is a tool used, which may be designed substantially block-shaped, through the block-shaped body, a channel leads therethrough, said channel starts in particular on an end face, as this is typically not blocked during use of the tool, the channel terminating at the bottom and Although close to the other end side of the parallelepiped shaped body, the channel preferably has a rectangular cross section, the cross section is elongated, the longer sides extending from below to above, the tool is used as an installation aid for installation of the panels projects on the underside of the tool a spring out, the spring is disposed below the channel, the spring tapers downwardly (as seen from the tool) and / or towards the front, with or "rear", "rearward", the front side is meant in the direction to which the channel region adjacent terminating at the bottom In one embodiment, the spring comprises a first n, the area lying in front, which is narrower than the succeeding rear portion, the narrower region may be about twice as long as the thicker region, the front end of the spring may be in

further taper compared to the narrow range in order to simplify the handling described below, namely, to bring the spring of the laying aid in the gap of a joint, which is provided by two matched in the aforementioned manner panels. provide a taper to the rear causes the laying aid eventually improved again from the joint can be pulled out,

The width of the spring being initially outwardly and in particular downward or forward so dimensioned that it can be inserted into the gap, the at least remains on the surfaces of two matched panels, the spring Tapered example sufficiently downward, so the spring can be brought in coming from above into the aforesaid gap by lowering, the spring correspondingly tapered toward the front, so this taper is inserted into the gap and so brought the spring between the panels, the wider portion of the spring is so dimensioned that in this way the two panels are pressed apart when the spring is further inserted between the panels, by the

is pushing apart the lace-up or pressed together rod-like member, which has been initially inserted in said groove, a lace-up or stαbαrfiges, preferably consisting of silicone

Element, which preferably has a rectangular in about

having cross-section, is inserted into the channel of the laying aid in preference forth from the end face, the dimensions are so

5 dimensioned such that the width of the cord-like member on the

Width of the channel is tuned Further, the height of the cord-like member is adapted to the height of the channel, there remains a small clearance between the cord-like member and the channel,

0

The cord-like member can easily be pushed through the tool because of the clearance and comes behind the spring back down to the fore The dimensions of the rectangular cross-sections are also selected so that the

will not twist cord-like element 5 within the channel,

Is the cord-like element pushed through the tool, the spring is tapered region between the first and the second panel in -0 brought in the located gap therebetween with a, it is then located, for example, at the beginning of the joint into which brought the cord-like member shall be,

The tool is provided in one embodiment of the invention with wheels _5 to easily moved with the aid of the rollers the tool along the joint seam, or the tool slides over the panels, there is the danger that the surface of the panels may be damaged,

30, the installation aid along the joint, which between them the

Panels is moved or moved and is in this case the spring in the gap of the joint, the panels are pushed apart first by the wider portion of the spring, the case is initially inserted into the groove of the first rod-shaped or

35 cord-like element, which for example has a circular cross-section and consists of rubber (round rubber), compressed. The wider region of the spring is dimensioned such that the second cord-like member which protrudes at the bottom of the laying aid, in which easily

5 connecting joint leads. There remains therefore preferred that a small

Game between the cord-like element and to facilitate the introduction of the cord-like element into the connecting joint, so the cord-like element comes usually from above the pressed apart panels

0 Coming into the connecting joint in,

If the tool is moved further along a joint, so the connection joint includes a little behind the laying aid again due to the pressure by the first compressed cord-

5 or rod-like member has been effected, has become the

Connecting joint somewhat closed again, the cord-like member due to an appropriately provided dimensioning and / or shape by form-fitting and / or frictional connection between two panels is fixed,

-0

The tool has at the rear end in an advantageous embodiment of a roller on which rolls above the connecting joint, This ensures that a smooth transition between the panels and the cord-like member on the

25 surface is achieved,

In one embodiment, the Verlehilfe is moved until the first transverse joint is reached, an eccentric member is pushed sideways parallel to the transverse joint between the second and the third panel 30th For this, a gap or a channel-like recess is provided, into which the eccentric elongated element can be pushed, it is pushed so that the narrower side of the eccentric element (eccentric) adjacent to the two panels, the dimensions are such that this easily can be pushed, In one embodiment, this may be a play between the eccentric element and the two panels remain,

If the eccentric element between the two panels have been pushed, it is by means of a lever moving the eccentric member by about 90 ° twisted a result, the gap of the gap widens, which third on the surface on the narrow sides between the second and panel is, Here, the rod- or cord-like member is compressed, which has been previously pushed into the transverse joint,

The eccentric element can be bent at one end so that this bent end in the lateral groove of the two

Panels can be inserted, the 90 ° rotated position is kept stable, otherwise, it must be ensured in some other way that the eccentric member is held in the twisted position. Thus, the eccentric member can be maintained manually.

Another cord-like element having a preferably approximately rectangular cross-section, is pushed from above, into the groove, which is located on the transverse sides between the second and the third panel. At the transverse sides, there is in particular the narrow sides, when the panels are rectangular, then the eccentric is rotated back to the initial position, the groove on the narrow sides closes slightly and the previously compressed cord or rod-like member, which is preferably located a

Round rubber is relaxed thereby, the rod- or cord-like element with preferably rectangular cross-section is now located in the fixed state between the second and the third panel, the fixing may have been achieved by positive locking and / or frictional engagement,

The eccentric member is pulled out of the channel, the laying aid process was continued until the next transverse joint is reached, In this way, the joints are provided with cord-like elements which are visible from above, until the panels completely edged with the lace-or rod-like elements are,

It has been shown that the panels can be laid over a large area by means of the invention without joints having to provide the flooring.

In one embodiment, the laying aid laterally a recess. The laying aid is moved during installation so that the recess is aligned with a gap resulting from a lateral side, in particular a narrow side, which recess serves to ensure that a lace-or rod-like member from the lateral side can be easily inserted so that zoom reaches this fully up to the lace-or rod-like member which is accommodated in a groove by means of the laying aid.

In another embodiment of the invention, the spring underneath the laying aid is such that this is all over their

so tapered length downward, the spring from above, can be used in the joint. This is particularly advantageous if walls defining the lateral access to a joint.

In one embodiment of the invention, there is in the groove to the

Top of the two panels adjacent, (a taper or step-shaped narrowing downwards, the laying aid the

Boat) with the underlying spring is matched to this groove, that the Auseinanderpresseπ of the two panels is accomplished only upon a pressure exerted in the lower area, ie in the area of ​​the narrowing or tapering,

Even in the compressed or relaxed state of the already loaded rod- or cord-like element which may be present particularly in the form of a round rubber, the spring of the laying aid is preferably with play within the joint seam in the upper part, is thereby achieved that the upper edge of the panels no is subjected to mechanical stresses, particularly when the laying aid is pulled out of the connecting joint. Otherwise, the top may be undesirably damaged and thus disturb the optics,

In a further embodiment of the invention, there is a

Recess inside the joint between two panels, namely is this recess, in particular above the aforementioned taper or stepped narrowing If the cord-like member inserted into the connecting joint, it fills the recess and in particular because of laterally clockwork or rod-like member projecting lugs, then it results in an improved hold of the rod- or cord-like element in the joint and in particular due to form fit. So then the rod or cord-like element is located between the two most reliable

panels,

In a simplified, particularly inexpensive embodiment of the invention, a laying aid is used which can be designed substantially block-shaped, a spring protrudes on one side of the cuboidal body, The spring is arranged in the aforementioned manner. By this tool it is possible to widen panels that a rod- or cord-like element can be inserted in the connecting joint between two panels without a frictional force to be overcome when the tool pulled out again, so the joints close again a bit so that the rod- or cord-like member is a break between the two panels. The simplified embodiment of the laying aid can be slid along the connecting joint also, behind the laying aid can rod- or cord-like element to be manually inserted into the widened region,

The rod- or cord-like elements or to the wishbone,

Narrow sides are inserted at least the Deckmaßlänge the transverse joint should have in order to obtain a closed surface, the Deckmaßlänge may typically be exceeded by about 1 mm when the transverse side ca, is 20 cm long, either, the laying aid a suitable

having cutting apparatus may be in the inserted a rod or cord-like element and accurately cut to the aforesaid extent this purpose, the laying aid, for example, a channel into which the rod- or cord-like element can be inserted in particular with a slight clearance.

The channel is adjusted in cross section to the rod- or cord-like member, a cutting tool is such that this so cut the cord-like member, for example, by pressing down that the desired length is present. This cutting tool may also be provided separately from the installation aid as a separate tool.

The material of the laying aid can be a metal such as aluminum. In order to produce the laying aid inexpensive, it is, however, preferably made by injection molding of plastic,

In one embodiment of the invention, at an upper or face side, the laying aid a relatively wide roll on, this is preferably significantly wider than the rollers at the bottom, as far as rollers are provided at the bottom, this role is on the top or front side to to roll finally again via the connecting joint, if a rod- or cord-like element undesirably protrudes a little out of the joint, can thus be improved upon to perform the roles in the laying aid, which are used to put pressure on the cord-like member around this N bring in into the connecting joint, are preferably made of a hard material, in particular a metal is suitable.

The rollers protrude at the bottom of the laying aid preferably as far out that the distance between the bottom of the laying aid and the panels is very low, the distance may, for example, in one embodiment, only a few tenths of a millimeter, for example be 2/1 0 mm, in this case, it is advantageous to manufacture also front rollers of the laying aid, which only serve to guide, of a hard material, the material should in any case be as little compressible, that the distance of 1/1 0 to 2/10 mm between the bottom the laying aid and the

Surface of the panels is maintained,

Although square panels are used, can not be distinguished between a longitudinal and transverse joint, The

However, laying method is identical in principle. Along a joint, a rubber is introduced by means of the publisher aid. Cross this running joints are forced apart by the eccentric and placed a cord-like element from above.

In one embodiment of the invention, adhesives are provided, with which the cord-like member improved in the joint is maintained. The adhesive may have been factory-applied to the panels, the adhesive may be incorporated into another embodiment in conjunction with the laying aid in the groove, the laying aid has advantageously a corresponding tank for a pressure-sensitive or adhesive is about a suitable feeding then the before the rubber is put into it is introduced into the adhesive joint seam. So it is particularly successful to provide a high-quality coating, which can also be laid by a handyman.

At the transverse sides and the joints extending transversely to the aforesaid gap, the adhesive may also be introduced manually with the aid of an appropriate tool or a tube.

Panels are advantageously used in which the narrow sides are joined together by lowering, first, a larger gap of, for example 2.3 mm remains between the two narrow sides of panels to be interconnected during the lowering movement, until the very end of this gap closes around 0.5 mm, This related displacement movement of a few 1 Otel mm is used to a cord-like member pressed between a connecting joint to bring which is provided on the surface, that is in the shaped panels on the surface, for example a gap is left of 2.5 mm , a string or rod-like member of 2 mm width may here initially be inserted, which is lowered a panel relative to the other Subsequently, the gap from the original 2 mm is reduced thereby, for example by 0.5 mm. Finally, as is the rod- or cord-like lightly pressed within the joint.

The intended coupling elements can also be used at the longitudinal sides, in the same way here the

Rubber are attached.

The material of the panels can be almost arbitrary. In the field of laminate flooring it is nowadays made of HDF or MDF, but it is no problem to use the fasteners even with tiles from a ceramic or stone,

In the following the invention will be explained in more detail with reference to embodiments 5,

Figure 1 shows two interconnected panels 1 and 2. This is in particular for a laminate floor panels, the panels are shown in the example 8

! 0 mm thick. The panel 1 side has a 2.5 mm deep groove

1, 9 mm wide. This groove 3 comprises an upper edge 4 and a bottom edge 5. The upper edge 4 is 2.8 mm thick. The lower edge 5 is longer than the upper edge 4. Outside the range of the actual groove 3, ie in the region of the lower edge 5, the

-5 protrudes opposite the upper edge 4, there is a

Recess 6. The recess 6 is formed by a sloping boundary wall 7 and a vertically extending boundary wall. 8 The inclined wall opens in a funnel shape in the direction of the floor surface. 9 With the

30 perpendicular to the floor surface is a 1 5 degrees angle included in the present case, the inclined wall 7 is to return from actual enriches the groove 3 to the recess 6, extending perpendicular to the floor surface 9 of the wall 8 forms a wall of the locking element 5 1 0, the locking member 1 0 is located at the open end of the projecting edge or lip 5 of the panel 1, the locking element 1 0 protrudes in this case over the bottom of the recess 6 by 0.7 mm, the wall 8 forms a contact or locking surface which contributes to the locking of the panels 1 and 2 parallel to the floor surface 9 and perpendicular to the joint 1 1,

The panel 2 side has a spring 1 2, the two panels in the connected state, the spring 1 2 located in the groove 3. The thickness of the spring 1, 2 is adapted to the width of the groove so that upward and downward no match is present, the open end of the spring 1, 2 has an obliquely extending boundary 1 3 on the lower side, there remains here, a distance to the adjacent edge 5 of the groove 3, the obliquely extending boundary 1 3 causes the spring 1 2 can be easily threaded into the groove 3, particularly, the recess 1 3 is adapted to introduce the spring 1 2 by means of a rotational movement about the connecting joint 1 1 round into the groove. 3

Below the spring 1 2 1 a projecting lug 4 is provided,

In this way a recess 1 5 is formed, which can be produced by milling from the underside of the panel 2, the wall 1 6, the transition between the recess 1 5 and the nose 1 4 forms, is perpendicular to the floor surface, the wall 1 6 simultaneously forms a locking or contact surface which is

, Interaction effects with the limiting wall 8, the positive locking parallel to the floor surface 9 and perpendicular to the joint 1 1, since the contact surfaces and locking surfaces 8 and 1 6 are perpendicular to the floor surface 9, thereby, a particularly secure positive

achieved lock between the two panels 1 and 2 in comparison with the prior art as it is known for example from document WO 97/47834 Al. The positive locking due to the locking surfaces 8 and 1 6 is further improved in that the above lower edge 5 is formed sufficiently rigid, the lower edge 5 is formed sufficiently rigid when the panels 1 and 2 are not connected by stacking sliding over within a plane 5 are can joining by displacement in a plane is also known from the aforementioned document WO 97/47834 AI known

To the positive locking parallel to the

0 floor surface and to improve vertical to the connecting joint 1 1 continues, the locking surfaces may be undercut 8 and 16, it is sufficient a deviation of a few degrees relative to the vertical course of the locking surface 8 is then thus inwardly toward the recess 6 is inclined towards,

5 Accordingly, the locking surface 1 6 inwardly in

Direction of the recess 1 5 inclined. In the connected state the locking surfaces interlock 8 and 1 6 then one another, This embodiment is particularly advantageous if the connection be made possible by moving in a plane

! 0 to. In this case, for example, the projecting edge 5 can be sufficiently far downwardly bent, so as to allow the joining by displacement in a plane, in order to provide improved sure that in the laid state is not an unwanted loosening by telescoping in a plane

-5 occurs, the aforementioned interlocking of the

Locking surfaces 8 and 1 6 particularly advantageous due to the interengagement hook prevents, for example, the lower edge 5 can flex away from shock.

The 30 below the spring 1 projecting lug 4 to the open

End of the spring is limited towards by a sloping wall 1 7, in the locked state, the limiting wall 1 7 extends parallel to the wall 7, in the locked state, as it is shown in the Figure 1, there remains a clearance between the wall 1 7 and the wall 7. This may be a few tenths of a millimeter. In the present case it is for example 0.5 mm.

Contacting the locking surface 8, the locking surface 16 so enters the aforementioned play of 0.5 mm between the delimiting wall 1 7 and the bounding wall 7. At the same time remains on the surface of the floor, a gap, which is for example 2.5 mm thick. There remains between the panels 1 and 2 in the locked state so a game before. This makes it possible to interconnect the panels, even though the locking surfaces are perpendicular or at least substantially perpendicular in the present example 8 and 1. 6 Even a undercut is possible The game is then typically 2/1 0 millimeters and more, how big the game should be suitably depends in particular on the shape and dimension of the contact surfaces 8 and 1 6 off A person skilled in the individual case by few experiments to determine how large the game should be at least to allow the connection even in steep, vertical or undercut extending contact surfaces 8 and 16, for this reason, it may also be expedient to provide a much larger clearance, for example, 1 mm,

In the locked state panel 1 with respect to panel 2 can be moved along the connecting joint 1 1, This may be desirable when laying to bring panels in the final position. Compared to the prior art, as it is known for example from document W097 / 47834 Al, the sliding takes place particularly easily,

In order to avoid that in the gap moisture and dust from entering, which remains on the surface 9 of the two panels at the connecting joint 1 1, or a lace-or rod-like element 1 8 is introduced, the lace-or rod-like member 1 8 has in this case a rectangular cross section and so corresponds substantially to the shape of the gap. The lace-or rod-like member 1 8 closes so flush and planar with the surface 9 of the panels 1 and 2 from,

The lace-or rod-like member 1 8 is preferably slightly wider than the gap into which the lace-like member or rod is inserted, in the present case it is thus somewhat wider than 2.5 mm, the depth of the lace-or rod-like member 1 8 corresponds to the thickness of the edge 4, in the present case, the lace-or rod-like member so 2.8 mm deep and is located on the upper side of the spring 1 2. This ensures that the lace-or rod-like member 1 8 does not enter so deep into the gap, that no surface is flush to the surface 9 is obtained,

The lace-or rod-like member 1 8 in the present case of a silicone material, this is elastic and can therefore be compressed,

The gap, in which the lace-or rod-like element 1 8 is fitted, expands downward In this case, the expansion proceeds in a funnel shape by the walls 1 9 and 20, The extension may be minimal, it just a few tenths of a millimeter. Through the expansion is achieved that the lace-or rod-like member 1 8 expands in the region of the recess when it is slightly wider than the gap. Hereby is achieved that the lace-or rod-like member 1 8 is stuck in the gap. An undesirable loosening of the lace-or rod-like member in the laid state is counteracted,

The lace-or rod-like member 1 8 can be introduced into the gap so the publisher process. However, it is also a panel 1 or 2 on the part of the manufacturer dαss already with the lace-or rod-like member 1 was connected 8, due to the compressibility of the material can be compared to the prior art, as from the publication W097 / 47834 AI is known, yet achieve the desired effects, a comparatively slight displaceability along a common connecting joint is possible with interconnected panels, joining is possible even with vertical or undercut extending contact surfaces 8 and 1 6,

The embodiment according to Figure 2 differs from the embodiment as shown in Figure 1, or in particular by undercut locking, contact areas 8 and 1 6. This is particularly well ensures that the panel 2 from the panel 1 can not be solved when the panel 2 in

Direction of the arrow 21 is drawn, in particular, an elastic edge 5, this embodiment is particularly advantageous

The embodiment according to figure 3 differs from the

Embodiments according to Figure 1 and Figure 2 by providing a more lace-or rod-like member 22 which is inserted between the locking surfaces 8 and 1. 6 This has the effect that the clearance between the panels is relatively large in relation to the embodiments according to

may be Figures 1 and 2 without the lace-or rod-like member 1 8 having to increase at the surface 9 of the panels 1 and 2. FIG. Moreover, the lace-capable or compensate for rod-like element 22 shrinkage effects, which can occur in particular if the panels are made of a wood material,

Panels are used having a rectangular surface, the embodiment is preferable in accordance with Figure 3 at the narrow sides, as this may make shrinkage effects particularly noticeable here, on the longitudinal sides, the effect of shrinkage effects is lower,

Consist panels from a wood material, as they shrink regularly at warm temperatures, are panels of a Hoizwerkstoff damp rooms exposed, these stretch regularly, The embodiment of Figure 3 is therefore preferably provided in areas that are heated regularly. Let us mention here, for example, a living room of a family home,

The lace-or rod-like member 22 or between the contact, locking surfaces is 8 and 1 6, in cross-section regularly smaller dimensions in comparison with the lace-or rod-like member 1 8, which is adjacent to the surface 9 of the floor , In the present case the cross section of lace-or rod-like member 22 is configured approximately square, the square is x 1 mm in size approximately 1 mm.

In the embodiment according to FIG 4 6, the recess a further recess or, recess 23, the recess 23 is adjacent to the locking surface 8, in the recess 23 is located when laying a lace-or rod-like member 22. In the uncompressed state projects beyond the lace-up or rod-like

Element 22 is partially from the further recess 23 out If panel 2 connected to the panel 1, the nose 1 4 presses first the lace-or rod-like member 22 is completely in the recess 23 inside, as indicated in Figure 4,

Is then moved in the direction panel 2 panel 1, so relaxing the lace-or rod-like element 22 and passes between the locking surfaces 8 and 1 6. This condition is illustrated in FIG. 5 An for the compressed element should have been shown elliptical. For the sake of clarity, the representation of reality differs.

In the embodiment of Figure 4, the length of the nose 1 2 is dimensioned so that the panel 2 can be brought by a vertical lowering with respect to the panel 1 to the position shown in Figure 4 position, the lowering movement is indicated by the arrow 24, is then panel 2 is pushed along the arrow 25 in the direction of the panel 1, the path around which the

Panel 2 is moved, is very small and can be limited to a few 1/1 0 millimeters, is the displacement very short, so the required for the installation times can be reduced accordingly, This is especially against the aforementioned prior art, the case , for example over the prior art, as it is known from the document W097 / 47834 Al,

An embodiment in which in a first step, a vertical lowering along the arrow 24 is possible is preferably used on narrow sides of a panel with a rectangular surface, such a connection type is then preferably on the longitudinal sides, wherein coupling by a rotational movement about the connecting joint 1 1 around succeeds such a prior art in which the joining by a

Rotary motion is effected, it is apparent for example from the publication WO01 / 48332 AI or from document US 4,426,820.

Is panel 2 along the arrow 25 in the direction of the panel 1 has been pushed, the situation shown in Figure 5 is achieved. In the connecting joint 1 1, a lace-or rod-like member 1 8 (final) will now be still inserted, and bonding is completed. It may be sufficient to merely move panel 2 by one to two millimeters, to move from the situation according to Figure 4 for the situation shown in Figure 5, this route is still relatively short compared to the routes that in the prior art, such as it is known for example from the publication EP 00843763 Bl, are necessary

In the Figure 6 that the panel shown in Figure 2 is locked by a rotational movement about the connecting joint 1 1 around with the panel 1 is indicated, in this case, the spring 1 2 may be compared to the embodiment shown in Figure 5 is relatively long, so that a connection is no longer possible, which initially comprises a lowering movement according to arrow 24 (Figure 4), then a relatively stable form-fitting connection is achieved perpendicular to the floor surface in comparison to Figure 4,

The lace-or rod-like member 22 may have a circular cross-section. The diameter is, for example, approx. 2 mm. The recess 23, in which the lace-or rod-like element 22 is partially, typically has a similar width. In the example case, the width would be 2 mm. The depth may be half the size, you would then be 1 mm,

Comprises a panel of two or lace-rod-like elements in the aforementioned manner, so may be a lace-or rod-like member

1 8 particularly simply introduced from the surface by the gap at the surface against the elastic properties of the lace-or rod-like member 22 is forced apart, first with the aid of an appropriate tool, in the pushed apart state, the width of the gap at the surface is then in particular wider than the width of the cord or bar-like element 1, 8, which is to be brought into the gap. The lace-up or rod-like element 1 8 can then be inserted especially easy. The tool is then removed and the panel 1 brought to the panel 2 due to the expansion of the lace-or rod-like member 22, stops This displacement due to the expansion of the lace-or rod-like member 22, as soon as a force equilibrium is reached, then remains at no gap the surface,

The lace-or rod-like member 1 8 on the surface 9, thus protecting against the ingress of dust and moisture,

In the figure 7, an advantageous embodiment of a cord or bar-like element 1 8 is shown, which is introduced from the surface. In cross section, this lace-or rod-like member 1 8 on both sides of a kind of barbs 26 and 27, the lace-order or rod-like

to squeeze element 1 8 particularly well side, is an arcuate recess 28 provided at the bottom. Further, the lace-or rod-like member 1 8 may have, for example, inside a thread 29, to prevent expansion effects, therefore, the thread 29 is comprised of a non-stretchable material, which is wrapped in accordance with Figure 7 of a compressible material such as silicone.

The visible in the installed state surface 30 of the cord or bar-like element 1, 8 may be surface configured to be able to achieve a two-dimensional degree with the panel surface. 9

Figure 8 shows two panels 1 and 2, in which the spring has been pushed into the groove 3 of the panel 1 1 2 of the panel. 2

The protruding edge 5 has a rectangular-section recess 30 at the top. The spring 1 2 has at the bottom a rectangular in cross-section recess 31, the two recesses 30 and 31 have the same width, they are laid on each other when the spring has been 1 2 of the panel 2 is completely pushed into the groove 3 of the panel 1 so that no gap remains in the common connecting joint 1 1, the recesses 30 and 31 form a channel into which a rod or cord-like element is pushed to the panel 1 and panel 2 parallel to the surface 9 and perpendicular to the connecting joint 1 1 to lock. The shifting of panel 2 in the direction of panel 1 succeeds to the position shown in Figure 8 position slightly because no protruding locking element has to be overcome in the state which is shown in Figure 8, further comprising moving a panel 2 succeeds very easily relative to the panel 1 along the common connecting joint, since the panels are locked only perpendicular to the surface. 9

Figure 9 differs from Figure 8 by a rod-like

Member 32 which is pushed finally into the space formed by the recesses 30 and 31 channel, the rod-like member 32 is at least almost as wide as the width of the recesses 30 and 31 so that no gap occurs at the surface 9 in the connecting joint 1 1, the material from which the rod- or cord-like member 32 is then preferably consists of a little or non-compressible material so as to avoid the creation of a gap at the surface 9 in the connecting joint 1. 1 Metal or a wood material can therefore be used as a material.

Forming the panels 1 and 2 in the embodiment shown in Figures 8 and 9, a closed surface, so it is useful for example for aesthetic reasons, also to provide such coupling elements on the other sides, that a closed

Surface is formed. In particular, it is advantageous to then form the narrow sides of a panel with a rectangular surface so that the final locking by pushing a rod takes place 32, such coupling elements are to be preferred, in which the joining takes place by means of a rotational movement about a connecting joint case on the longitudinal sides then also no gap remains on the surface 9 between two panels 1 and 2, the joint 1 1 is thus closed, In Figure 10, this embodiment is shown, the

Contact surfaces 8 and 1 6 are oblique in order to allow a connection by means of a rotating movement in spite of a lack of game The above edge 5 is preferably rigid form, to ensure a stable locking of the panels 1 and 2 in the installed state,

If the panels 1 and 2 arranged in an alternative to Figures 8 and 9, so that remains on the surface 9 at the connecting joint 1 1, a gap, so in this expedient a rod- or cord-like element 1 8 is introduced, which for example of silicone or rubber, expediently, the rod- or cord-like member 32 made of Teflon or a material with comparable flexibility and smooth surface, Then, the pushing of the rod- or cord-like element 32 succeeds in through the recesses

30 and 31 channel formed relatively easily and in particular, when the narrow sides of a panel are designed to replace the narrow sides compared with the longitudinal sides namely lower friction forces, which counteract a pushing against

The rod-like member may be shaped differently in cross-section, so that this may be constricted, The cross sections of the recesses 30 and 31 are then formed advantageously to correspond so that undercut contact surfaces

8 and 33, and 34 and 35 are present, Figure 1 1 illustrates the embodiment in order not to have to pay attention to a particular position during insertion, has the rod-shaped element has a circular cross-section, corresponding semi-circular recesses 30 and 31 are formed, as shown in Figure 1 2 it is shown

The pushing of the rod 32 is particularly easy, if at least one side tapers to a point, then preferably run both side too narrow, so that the user or does not need to pay attention consumers, should be used with which the end of the rod is threaded into the channel.

In Figure 1 1, the case is shown that the recesses 30 and 31 taper toward the opening. The associated rod-shaped element 32 has a constriction This results in undercut contact surfaces, This embodiment is particularly advantageous if the flanks 4 and 5 of the groove 3 are the same length, since then they are relatively thin and therefore relatively flexible,

Figure 1 2 shows an embodiment in which the locking member 36 of the panel can be made 2 by vertically lowering it into the recess of the panel. 1 The two locking elements 36 and 37 have semi-circular recesses 30 and 31, in the final locking for the purpose of a round rod 32 is pushed. At the connecting joint 1 1 no gap or clearance remains. It suffices a vertical lowering of panel 2 with respect to panel 1, without panels must then be moved for joining.

If there are not provided on all sides of a panel connecting elements according to Figure 1 2, it is again particularly advantageous to provide for a panel with a rectangular surface at the longitudinal sides of an embodiment in which the connecting is performed by a rotational movement about a connecting joint 1 1, by way of example this, refer to Figure 1 0, which shows such coupling elements, an embodiment according to Figure 1 2 is then provided on the narrow sides, If such a panel with another to the

Longitudinal sides connected by a rotary movement about the common connecting joint around, it may also be connected to a neighboring, already laid panel on narrow sides, without that this panel has to be finally moved to the final position for final

Locking is then pushed only one rod 32 into the channel formed by the recesses 30 and 32nd

The shape of the recesses 30, 31 and 37 and the locking element 37 can be shown by the figure 1 in the 2

Embodiment differ. It is only important that the forms are such that the desired glueless locking in these directions is finally possible

By the invention it is possible, the following procedure for the

provide connecting two panels, a panel 1 is brought into contact with a panel 2 so that recesses 30 and 31 form a channel, the coupling elements are arranged so that then the panels are locked in a first direction in the channel is then a rod-shaped

Element pushed. The coupling elements are arranged so that then the two panels are interlocked both perpendicular to the common surface 9 and parallel to the common surface 9 and at the same time perpendicular to the connecting joint 1. 1

The element 32 can be composed preferably with a high restoring force also made of an elastic material, it may then already have been fixed in the factory in one of the two recesses 30 or 31, the cord-like member is then in particular of silicone or a hard - PVC,

A rod- or cord-like element according to the invention is particularly present when the diameter of at least 0.5 mm, preferably at least 1 mm, instructs the rod- or cord-like element has a rectangular cross-section, so amount to length and width of the rectangle preferably at least

0.5 mm, more preferably at least 1 mm, a rod- or cord-like element according to the invention is in particular also present if it is a separate part which can be bonded as such in an embodiment having a panel, The physical properties of do not change it.

Then such a rod- or cord-like element in one embodiment of the case is to be distinguished, in which a

Paste or the like is applied to a panel in a flowable state, and the paste then solidifies,

Figures 1 3 and 1 4 show embodiments of a further development shown in Figures 4 and 5

Embodiments illustrate,

In the Figure 1 3, the coupling elements on the longitudinal side of an already laid panel 1 shown in section, the panel 1 comprises laterally at the longitudinal side of a lower projecting edge 5 that in the above edge 5 there is a groove-shaped recess 6 with a groove-shaped recess 23. In the recess 23 within the recess a cord has been inserted 22nd The cord comprises a tendon or, thread 29 of a material having low elastic properties, which is surrounded by a rubber or silicone, due to the tendon does not alter the cord 22 length, a second panel 2 has its longitudinal side of the first panel 1 obliquely applied and brought by pivoting into the common plane of the panel. 9 In this way the panel 2 has been connected to the already laid panel 1 so that these are connected in parallel to the common surface 9 as well as perpendicular to the common joint 1 1 by positive locking with one another,

The spring 1 2 of the panel 2 in the present case just short enough to connect the panel 2 by lowering the panel 1 in the aforementioned manner, after the lowering of the panel would have 2 yet to be pushed in the direction of the panel 1 in order to to get in FIG situation shown 1 3, The

2 spring 1 could be longer since a connecting by obliquely applying and then pivoting on the longitudinal sides is generally unproblematic

A second panel 2a was applied obliquely to the longitudinal edge of the first panel 1 installed and connected by pivoting with the latter in the aforementioned manner,

The narrow sides of the panels 2 and 2 shown in Figure 14 are such that the locking members 1 4 and 1 0 grip behind each other when said one panel 2a is lowered suitable relative to the other panel 2, panels With an appropriate positioning of the two last-mentioned 2 and 2a there is after the lowering of the panel already 2a a lock joint the two panels 2 and 2a parallel to

Surface 9 and locked perpendicularly to the common connecting joint 1 1 with each other, then the two last-mentioned panels 2 and 2a are fed successively pushed. The spring 1 2 2a of the panel reaches into the groove 3 of the other panel 2. The two panels 2 and 2a are thereby also vertically connected to floor level, as shown in the figure fourteenth When appropriate, the two most recently installed panels 2 and 2a in the direction of the already laid panel 1 is pushed, whereby a classical tongue and groove connection is also provided between the panel 1 and the panels 2 and 2a, respectively, by the classical tongue and groove the two panels 1 and 2 and 1 and 2a are locked vertically to the common surface 9 by a positive connection with one another 5,

The projecting lip 5 on the narrow side of the panel 2 also has the groove previously described 6 having a recess 23, the recess 23 is adjacent to the upwardly projecting

0 locking element 1 0 which or at the open end of the protruding lip, flank 5 is, in the pushed-together state of the two panels 2 and 2a is the cord-like member 22 having a circular cross-section in the Figure 1 4, pushed into the channel,

5 which is formed by the above-mentioned recess 23 and the area of ​​the latter panel 2a located thereabove, the locking element 1 4 of the panel 2, which extends downward, contributes to the provision of the channel into which the cord-like member 22 - as shown in Figure 1 4 shown in section

-0 - has been pushed, the dimensions may be selected such that between the cord-like member 22 and the aforementioned channel remains a game, the pushing of the string-shaped member 22 then takes place particularly easily,

-5 will now that in Figure 1 5a in a side view and in the

FIG tool 40 shown in a front view 1 5b used. The base body 41 is configured substantially cuboidal. Due to the block-shaped body 41, a channel 42 leads through the channel 42 begins at one end face 43 (front), as these

30 end face is typically not blocked during use of the tool 40th It ends at the bottom 44 and that close to the other end face 45 (rear) of the parallelepiped body 41st The channel 42 has a rectangular cross-section, as shown in Figure 1 5 is to recognize b, it expands preferred example, the end face 43 back in order to facilitate the pushing of a cord-shaped member 1 8, The longer sides 45 a of the rectangular cross-section extend parallel to the side walls of the tool 40, that is from bottom to top, the

5 dimensions of the cross section of the channel 42 are thus adapted to the cord-like member 1 8 that this will not rotate within the channel 42 so the cord-like element 1 8 is in the embodiment shown, due to the adjustment not possible in practice, rotated by 90 ° in the channel 42

introduce 0,

The tool 40 is used as an installation aid for installation of the panels 1, 2, 2a, with the support of laying aid the cord-like element 1 8 is placed in the joint 1 1, which is formed by the 5 panels 1 and 2,

On the underside 44 of the tool 40 a spring 46 protrudes, The spring 46 is disposed below the channel 42, The spring 46 tapers downwardly (by the tool 41 as seen) as shown in: 0 Figure 1 5b it becomes clear

In one embodiment, the spring 46 includes a first, lying in front area 47 which is narrower than the subsequent rear portion 48, the narrower portion 47 - as in Figure

! 5 15a seen - preferably longer, so for example, about twice as long as the thicker portion 48 in order to simplify the handling, the front end 49 of the spring 46 can continue to rejuvenate compared to the narrow portion 47 to the spring of the installation aid to be brought into the nip of a joint 1 1, the

30 because of two matched in the aforementioned manner

Panels 1, 2 is present to provide a taper 50 of the spring 46 to the rear, provides improved sure that the laying aid 41 may eventually again be pulled out of the joint 1 1, in particular without damage to the panels 1, 2 to cause,

The width of the spring 46 is first of all outwards and in particular downward or forward so dimensioned that it can be inserted into the gap of the gap 1 1, the at least remains on the surfaces of two matched panels 1, 2, Tapering the spring 46, for example, sufficiently downward, so the spring can be brought in 46 in the above-mentioned gap 1 1 from above, by lowering, the spring 46 tapers towards the front, this can taper 47, introduced into the gap 1 1 49 and the spring 46 are placed between the panels 1; 2.

The wider portion 48 of the spring 46 is dimensioned such that in this way the two panels are pressed apart 1 and 2, when the spring 46 is further inserted between the panels 1 and 2 and so the wider region 48 suitable passes between the panels 1 and 2, by pushing apart the cord-like member 22 is compressed, which has been initially inserted into the recess 23 of the present in the form of a groove recess 6 of the panel 1,

A lace-up or rod-like, preferably consisting of silicone element 1 8, which preferably has an approximately rectangular or at least elongated cross-section is inserted into the channel 42 of the laying aid 41 preferred, the dimensions of the end face 43 here so dimensioned that the width of the cord-like member is matched 1 8 to the width of the channel 42nd Further, the height of the cord-like member

1 8 matched to the height of the channel 42nd There remains a play between the cord-like member 1 8 and the channel 42, so that the cord-like member through the channel may be pushed through the 42nd The cord-like member 18 can be pushed due to the backlash by the tool and comes behind the spring 46 close to the rear end wall 45 on the underside 44 reappears, the dimensions of the approximately rectangular

Cross-sections are chosen so that the cord-like member 1 8 will not rotate within the channel 42 when it is pushed or pulled through the channel 42,

Is the cord-like member 1 8 pushed through the tool 40, the spring is tapered portion between the first panel 1 and second panel 2 brought in 46 with one going into the gap therebetween 1 1, The laying aid 40 is then especially at the start a joint 1 1, in which the cord-like member is to be brought in.

The laying aid or the tool 40 is provided in an embodiment of the invention, with rollers 51 and 52 to easily with the aid of the rollers 51, 52, the tool 40 along the

to proceed connecting joint 1 1, Otherwise, the tool 40 slides over the panels 1 and 2, there is thereby a risk that the surface of the panels may be damaged. 1 and 2

If the laying aid 40 along the gap 1 1 which is located between the panels 1 and 2, moved or moved and is in this case the spring 46 in the gap of the gap 1 1, so the panels 1 and 2 are first by the wider portion 48 of the spring 46 are pressed apart. Here, the first 23 is inserted into the first cord-shaped groove or the recess

Element 22 compressed. The wider portion 48 of the spring 46 is dimensioned such that the second cord-like member 1 8, which protrudes on the underside 44 of the laying aid 40 is easily pressed into the connecting joint 1. 1 The dimensions are preferably such that there is a small clearance between the element 1 schnurαrtigen 8 and pushed apart panels 1 and 2 remains in order to facilitate the introduction of the cord-like member 1 8 to the connecting joint 1. 1 So the cord-like element 1 8 passes usually coming from above into the connecting joint one first

If the tool 41 is further moved along a joint 1 1, then the connecting joint 1 1 a bit closes behind the laying aid 40 again due to the pressure which has been caused by the first compressed string-like member 22, has become the connecting joint 1 1 something is closed again, the cord-like element 1 8 is retained due to an appropriately provided dimensioning and / or shape by form-fitting and / or frictional connection between two panels 1 and 2,

The tool 40 has at the rear end near the end wall 45 in an advantageous embodiment, a roller 51, which rolls above the connecting joint, This ensures that a smooth transition between the panels 1 and 2 and the cord-like member 1 8 to the surface is achieved.

This FalTwird not shown in Figures 1 and 5 a 5 b 1,

In one embodiment the laying aid 40 is moved until a first transverse joint 60 is achieved, as shown in Figure 1 6, which shows a plan view of the panels 1, 2, 2a, the rear

Laying aid 40 is then already enters the gap 1 1, a cord-like element 1 8in.

An eccentric member 70 which is shown in section in Figure 1 9 is pushed laterally parallel to the transverse joint 60 between the second panel 2 and the third panel 2a. For this purpose, a gap or, preferably, a channel-like recess 71 (as shown in FIG. 1 7 shown) in the panel 2 and / or in a panel 2a is provided into which the eccentric elongated member 70 can be pushed. The eccentric element 70 is pushed in that the narrower side of the eccentric element (cam) to the two panels 2 and 2a adjoins. The dimensions are such that it can be pushed easily. In one embodiment, the

Support remains a clearance between the eccentric member 70 and the two panels 2 and 2a,

If the eccentric element 70 has been inserted between the two panels, as is the eccentric member 70 is rotated by means of a lever 73 shown in the figure 1 9 by approximately 90 °, as indicated by the arrow 72 in Figure 1. 7 In this way, the gap 60 shown in the figure 1 6 expands, which is located at the surface on the transverse sides between the second panel 2 and the third panel 2a, as a result of the 90 ° -

Rotation compresses the cord-like member 22 which has been previously pushed into the channel provided within the transverse joint 60, The twisted by 90 ° position of the eccentric element shown in FIG 1 to 8,

The eccentric element 70 may be at the end of the lever 73 is bent so that this bent end 74 can be introduced into the lateral groove of one of the two panels 2 or 2a, the 90 ° rotated position of the eccentric element 70 is held. Otherwise, it must be ensured in some other way that the eccentric member is held in the twisted position 70th

In order to facilitate the introduction of the eccentric member 70 in the appropriate channel 71 or a sufficiently wide gap, has this preferably has a taper 75, this tapered portion is first inserted in the appropriate channel 71 or the provided sufficiently wide gap, A another schnurαrtiges element 18 having a preferably approximately rectangular or oblong cross-section can be pushed from above, into the gap, which is located on the lateral side 60 between the second panel 2 and the third panel 2a, it may alternatively from the side be pushed out, especially since the dimensions are dimensioned in this position so that the cord-like element 1 8 is located with play in the joint, as is illustrated in FIG 1 to 8,

In the transverse side 60 is in particular a

Narrow side, when the panels 1, 2, 2a having a rectangular surface,

Subsequently, the eccentric 70 is rotated back to the initial position, the groove on the transverse side 60 closes slightly and the previously compressed cord-like member 22 relaxes here, the cord-like element 1 8 is now located with the preferred rectangular cross-section in the fixed state between the second panel 2 and the third panel 2a, the fixing may have been achieved by positive locking and / or frictional connection, according to Figure 1 7, the fixation is achieved in particular due to form fit, but also due to frictional connection, because then the cord-like member 1 8 with the preferably elongated cross-section is slightly pressed in the groove,

The eccentric 70 is then or out of the channel 71, drawn out a respective gap. The installation aid 40 will proceed until the next transverse joint is reached. In this way, the joints are 1 1, 60 (respectively column) with cord-like

1 provided elements 8 which are visible from above, to the panels 1, 2, 2a are completely surrounded with the lace-or rod-like elements 1 8. It has been shown that the panels can be laid over a large area by means of the invention without joints having to provide the flooring,

In one embodiment, 40 has the laying aid a laterally

Recess, the laying aid 40 is moved during the installation so that the recess is aligned with a gap resulting from a lateral side 60, in particular a narrow side, the recess serves to ensure that a lace-or rod-like member from the transverse side 60 forth easily so can be inserted, that this approach extends completely up to the lace-or rod-like member 1 8, which is brought into a gap 1 1 by means of the laying aid,

In a further embodiment of the invention, the spring 46 is below the laying aid such that it tapers over its entire length as the downward direction, that the spring from above may be coming inserted into the joint, this is particularly advantageous when walls defining the lateral access to a fugue,

In one embodiment of the invention, there are in the joint 1 1, which is on the top side 9 of the panels 1, 2, 2a borders, a taper or step-shaped narrowing 76 downwardly, the tool 40 with the underlying spring 46 then so on this joint matched with the narrowing 76, that presses apart the two panels 1 and 2 is achieved only on the basis of a pressure or in the lower area, ie in the region of the constriction 76,

Rejuvenation is applied,

Even in the compressed or relaxed state of the already loaded rod- or cord-like element 22, which in particular has a circular cross-section, there is the spring 46 of the laying aid 40 with play within the connecting joint 1 1, as far as the upper portion, that is affected above the constriction 76 is thereby achieved is dαss the upper edge of the panels is exposed to 1 and 2 to mechanical stresses, particularly when the laying aid is pulled out of the connecting joint 1 1 40, Otherwise, the upper edges of the panels 1 and 2 could undesirably damaged, and thus the optics are impaired,

In a further embodiment of the invention, there is a recess 11 within the joint 1 1 between two panels 1 and 2, and indeed is this recess, in particular above the aforementioned taper or step-shaped constriction 76. When the cord-like member 1 8 to the connecting joint 1 1 inserted, it fills the recess 77 and in particular laterally due to clockwork or rod-like member 1 8 projecting lugs 78, it then results in an improved hold of the rod- or cord-like element 1 8 in the joint 1 1 and due to the mold closure thus obtained, the rod or cord-like element 8 then 1 thus sits particularly reliable between the two panels 1 and 2,

In one embodiment of the invention, the laying aid 40 to an upper or end side of a relatively wide roller 80, which are in particular wider than the wheels or rollers 51 and 52,

This is therefore preferably considerably wider than the wheels on the bottom. This roller 80 is at the top or front side to finally to roll again about the connecting joint 1 1, 60th If a rod- or cord-like element 1 8 a little undesirable for the joint 1 1, protrudes 60 can be improved this way. The rollers 52 and 80 in the laying aid 40, which serves to exert pressure on the cord-like member 1 8 to bring in this true in the connecting joint 1 1, 60, preferably consist of a hard material. In particular, a metal is suitable. The rollers 51, 52 protrude at the bottom of the laying aid 40 preferably projecting so far that the distance between the bottom of the laying aid and the panels 1, 2 is very low. The distance can, for example, in one embodiment, only a few tenths of a millimeter, for example be 2/1 0 mm, In this case, it is advantageous also front rollers 51 of the laying aid 40, which merely serve to guide, to be made of a hard material , the material should be slightly compressible in any case, that the distance of 1/1 to 2/1 0 0 mm between the bottom of

Laying aid 40 and the surface 9 of the panels 1, 2 is maintained.

Figure 20 shows a further embodiment of the invention, namely panels 2 and 2a, in which at least one side by

Lowering may be connected with each other, This is to be understood that a panel 2a can be held parallel to the already laid panel 2 and lowered for the purpose of connecting, During the lowering of the parallel position can be maintained Is panel 2a has lowered to the extent that it then is in the same plane as the panel 2, so there is a by projecting below nose 14 in an upwardly open recess 6, parallel to the surface 9 and perpendicular to the joint, the panels 2 and 2a then locked together by form-fitting, the at the end of the lower projecting lip 5 upwardly directed locking element has been bent slightly then outwardly, which can be aided by a chamfer 90 in particular, which is located advantageously below the locking member,

Initially remains on the surface 9 of the panels 2, 2a, a gap of for example 2.5 mm, is now a cord-like member, for example, 2.2 mm width put into this gap, it without problems since there is a clearance, After inserting of the cord-like member is the panel 2 ca, pushed 0.5 mm in the direction of the panel 2, so that the relatively short here spring reaches into the groove 3 1 2 and so a locking is obtained vertical to the surface 9, this shifting movement of a few l Otel mm is used to compressed the cord-like member to bring between the connecting joint that is provided on the surface 9,

The coupling elements according to FIG 20 can be used on all sides, since the locking in the vertical

Direction is relatively weak, it is preferable to use these coupling elements which include a relatively short projecting into the groove 3 of spring 1 2, only on lateral sides 60,

Figure 21 shows an embodiment of the invention which is to be preferred if only one rod- or cord-like element 1 8 is brought from the top side 9 forth between two panels 1 and 2, the cord-like member is not between the two panels 1 and 2 in brought the manner shown, so are the two

Preferably such panels locked together, that a small clearance remains,

The panels 1 and 2 shown in Figure 21 are such that a gap remains at the top in the joint 1 1, The gap is preferably somewhat less wide (a few tenths of a millimeter) than the rod- or cord-like element 1 8. If the pushed rod- or cord-like member from above into the gap so passes this then slightly compressed into the gap. This ensures that the top is watertight. Moisture problems are avoided,

The gap shown in Figure 21 extends in the embodiment shown to the upper side of the spring 1 2 For manufacturing reasons, it is expedient, but not necessary for the practice of the invention,

In order to ensure an accurate and reliable fit of the rod- or cord-like element 1 8 between the panels 1 and 2, it is held by positive locking in the desired position. In the present case, there is within the gap at least one, preferably two projecting noses 95, which are laterally connected to the respective panel, These projecting tabs serve not only to the aforementioned form-fitting, but also form a constriction in the interior of the groove, the narrowing of the groove is of advantage to using a tool (laying aid) to press the two panels in the manner already described apart without damaging the edges at the surface 9,

A rod- or cord-like member 1 8 as can be used in the processes shown in Figure 21 panels 1 and 2 is shown in Figures 22 and 23 in section, It has laterally at least one and preferably two recesses 96, the recesses 96 so cooperate with the projecting lugs 95 that in this way the desired fit is achieved,

At the bottom of the rod- or cord-like element 1 8 there is preferably a groove 97, In this way, the rod- or cord-like

Element 1 8 has two legs which can be sufficiently pressed together easily, it is particularly easy to push in the rod or cord-like element 1 8 in the gap provided in the joint 1 1,

On the underside of the rod- or cord-like element 1 8 is tapered like a funnel, through the corresponding inclined surface portions 98 ensures that the stαb- or schnurαrtige element 1 8 can be easily brought into the gap,

The rod- or cord-like element 1 8 shown in Figure 22 is preferably made of a relatively hard, but still sufficiently elastic material, for example of a hard PVC material,

Preferable is the embodiment shown in Figure 23, Here, an upper portion 99 of the rod- or cord-like

Elements 1 8 made of a comparatively soft elastic material such as a what PVC material, if the lower portion 1 00 is made of a relatively hard material such as hard PVC, the area of ​​harder material provides particularly well the ordnungsgemäßigen reliable fit a rod - or cord-like element between two panels 1 and 2, which ensures a relative soft portion 99 existing part, that the rod- or cord-like element 1 8 can be pressed together here, so it is ensured that the rod- or cord-like element 1 8 can enter into the gap between two panels 1 and 2 completely, even if it is slightly narrower, the upper section 99 is then seated advantageously slightly pressed between the two panels to protect against moisture, dust, etc.
