Description

The The invention relates to a compound for plate-shaped Building elements, in particular for floor panels according to the preamble of claim 1 and Floor panels made with it.

Under the keyword "glueless connection" or "click connection" currently offered a variety of solutions, in particular for laminate floors made of HDF / MDF or for parquet flooring application Find.

At one in the EP 0 098 162 B1 known solution adjacent peripheral edges of the floor elements or panels, ie the longitudinal edges and the front or transverse edges are executed with a tongue and groove connection. The lower, facing a bearing surface groove cheek of a panel is extended beyond a vertical parting plane between the panels out and has at its end portion a locking projection which dips into a corresponding recess on the underside of a spring of the other floor panel. In order to facilitate the laying of the panels, the connection is made in the engagement region of the extended groove cheek with the spring with a game, so that a displacement of the panels along the longitudinal edges is possible.

In the WO 97/47834 A1 a glue-free connection is shown in which, similar to the above-described solution, the lower groove cheek of a floor panel extends beyond the vertical parting plane and is provided with a projection which engages in an associated locking recess of the spring. In contrast to the solution described above, engagement between the elastically deflectable elongated groove cheek and the associated locking recess of the spring is carried out without play.

adversely in these known solutions is that the lower groove cheek each must be made elastic to bring about the locking engagement to be able to. In unfavorable conditions, for example in case of material defects or excessive Loading the elastically deflectable lower groove cheek or swelling Due to humidity and the influence of temperature it can happen that cracks occur in the connection area of the lower groove cheek, so that this can no longer fulfill their locking function.

In the DE 199 62 830 C2 The Applicant is proposed to solve this problem to perform the horizontal locking via a separate locking pin, which is formed in addition to a conventional tongue and groove connection. Even with a breakage of this locking pin, the relative arrangement of the panels in the vertical direction is ensured in this technically superior solution.

Especially the latter two solutions are preferred by pushing together in the horizontal direction connected to each other. Some customers, however, prefer to angle the panels to connect with each other, being to an already laid panel a panel to be laid in inclination along the Longitudinal edge is attached, so that for example the spring of to be laid panel dips into the groove of the laid panel. Subsequently, the panel to be laid from its oblique position folded down, with the groove completely in the spring dips and horizontal locking devices into each other intervene that the two panels so along the longitudinal edge locked in both the horizontal direction and in the vertical direction are. The problem with such a solution is that the Locking at the shorter end or transverse edges at the above-described Einschwenkvorgang is difficult to produce so that - depending on the constructive solution - along the front edges either no vertical locking takes place or but this can only be produced with considerable effort.

That's how it shows DE 299 24 454 U1 a solution in which the floor panels are locked along their end edges in the vertical direction via one or more end projections of a panel, which engage in corresponding recesses of the other panel. These projections must be made relatively small by design, so that on the one hand, the production is likely to cause difficulties, on the other hand laying is done with extreme caution, so as not to damage the small locking projections.

In the DE 201 12 474 U1 and EP 1 350 904 A1 a glue-free connection is disclosed in which the above-described front projections are formed on a spring tongue over which an elasticity in the horizontal direction is provided, so that the engagement of these projections. is simplified into corresponding recesses of the other panel. In this solution, the vertically effective part of the locking projections is made relatively small, so that when laying a special attention must be paid to ensure that these locking projections are not damaged when swiveling down the panel to be laid on the front edge.

The JP 07300979 shows a glueless connection, in the front side only a horizontal lock is provided. A locking in the vertical direction is in the region of the end edges in this known solution is not provided.

To improve the locking is in the DE 10 2005 002 297 proposed a compound in which the locking takes place via an elastic spring tongue, which is used as a separate component in the front edge region of the panels. The spring stiffness of this spring element can be very easily and essentially adapted without regard to the material of the panels to the respective conditions of use. The disadvantage of such a solution is that the production is relatively expensive, since a separate component must be punched, bent and fixed to the panel.

A similar solution is in the EP 1 415 056 B1 disclosed. In this variant, a spring tongue of an elastic insert is supported from below on a shoulder of the other component in order to effect a vertical locking.

In the EP 1 650 375 A1 is disclosed a solution in which a spring is inserted for locking in a sliding groove of the components, which is formed in the plan view approximately U-shaped. In the unlocked state, the base of this U-shaped spring protrudes outwards and is deformed when attaching the other component inwardly into the sliding groove and then snaps after the complete down pivoting of the other component in a recording on this component, so that the elements are fixed in position.

Solutions, in which the frontal vertical locking via integrated or effected as an insert running spring elements is referred to in professional circles as "push-button connection", because of the swinging down the panel to be laid in a Locking recess of the other laid panel latching locking projection similar how a push button works. In practice, however, it turned out that such push-button connection either the desired Vertical locking can not effect under heavy loads or require a relatively high manufacturing expense.

In contrast, The invention is based on the object, a simply constructed To create a connection for plate-shaped components, by lowering one component with respect to another Allow the component to engage and provide a reliable one Vertical locking guaranteed.

These Task is performed by a connection for plate-shaped Components with the features of claim 1 and by floor panels solved with such a connection.

The inventive concept dissolves from the conventional constructions, where each one resilient spring element snaps into the locking position and there is a kind of slider used from a release position, in which there is no horizontal locking, in a locking position is adjustable. This adjustment can, for example, by the Connect the two components or arbitrarily through take a further step. The inventive Solution makes it superfluous, expensive use spring elements to be produced, since the locking engagement by actively moving the slider. Under the term Slider is not necessarily one in the linear direction adjustable element, but it can also be a rotary valve be a rotational movement or a combined linear and Performs rotational movement or pivoting movement.

One Such slide can be particularly simple as a flat Perform component, so that the manufacturing and assembly costs are significantly lower than in the solutions described above.

at a preferred embodiment of the invention the slide in a slotted guide along an edge led the component so that it when moving in the longitudinal direction the edge is adjustable in the locking direction.

These Adjustment in the locking direction is preferably via a control cam in the backdrop or on the slider, along the a control cam of the other component slides off, allowing the slider movement preferably a component of movement in the direction of the edge and a component of motion perpendicular to it, d. H. in the locking direction Has.

The Adjustment of the slider is particularly reliable, if this is done with a variety of cams, the with corresponding cams on the slotted guide work together. Of course, in kinematic reversal also the cams on the slide and the cams on be executed the slide guide.

The Manufacturing is particularly easy when two cams and two corresponding cams are provided.

The Control cam is preferably formed as a concave Stirnausnehmung, which can be easily trained by a router.

The adjustment of the slider can be simplified if the control cam and the curves to an adjacent edge of the device, at For example, offset to a longitudinal edge, so that the slide is mounted virtually eccentric.

These Training allows, for example, the slide to project in the release position with an end region, so that, for example, when preparing a further component of this runs on this projecting end portion and the slider actuated. However, the operation of the slider can also arbitrarily by the laying person over take the end section.

Of the Slider is preferably slightly shorter than the edge length carried out of the component, so that the horizontal lock on extends a wide range.

In its locking position, the slider engages behind a locking shoulder on the other component. This locking shoulder can by a End groove be executed on this other component.

The Horizontal connection of the components is preferably via a conventional hook connection with a projection on an element that dips into a recess on the other element.

there it is preferred if the slider above the engagement area the hook connection is executed.

Of the Slider can be easily made of wood, metal or plastic produced by stamping, injection molding or machining become.

The compound of the invention is particularly advantageous to use in floor panels, where at the longitudinal edges of a connectable by angling lock connection is provided so that the compound of the invention is executed on the front edges.

One preferred embodiment of the invention is hereinafter explained in more detail with reference to schematic drawings. Show it:

1 the front edge region of two connected by a compound according to the invention floor panels;

2 a sectional view of the front edge region of the panels 1 ;

3 a sectional view of the panels in the locked state;

4 a plan view of the panels in the locked state and

5 a sliding bar in the 1 to 4 illustrated connection.

The Invention can be applied, for example, to panels for floor, Wall or ceiling paneling use, with the application Floor panels, however, should be the most common. These floor panels can be parquet panels, for example with 3-layer or 2-layer structure or laminate floors or the like.

1 shows a section parallel to the laying plane by two frontally interconnected panels 1 . 2 , which generally have a rectangular shape, wherein at the longitudinal edges of a so-called lock connection is provided, in which the panels are connected by an angle. Such Lockverbindungen are well known and, for example, on the Domgin www.Hamberger.de the applicant described. The compound of the invention is at the shorter end edges of the panels 1 . 2 intended.

The aforementioned lock connection along the longitudinal edges of the panels 1 . 2 consists essentially of a spring 4 and a groove 6 , in the representation according to 1 a lower, projecting groove cheek can be seen. By applying the spring 4 in the groove 6 engage locking elements, which in the illustration according to 1 are not visible, so the panels 1 . 2 can be connected to adjacent panels along the longitudinal edges. The connection along the shorter end edges takes place via the end edge connection according to the invention. To visualize them is in 1 a sectional view chosen. The section runs along the line AA in 2 , This cut line extends, for example, in a parquet through the dividing plane between a precious wood layer and an underlying central layer of solid wood (3-layer structure) or a support layer of wood or HDF / MDF (2-layer structure).

As can be seen in particular from the sectional view according to 2 which gives a section along the line BB in 1 shows is at front edges 10 . 12 the two panels 1 . 2 a hook connection 14 running over the two panels 1 . 2 in horizontal direction (horizontal in 2 ) are connected. Such hook connections 14 are known from the prior art, so that only those essential for understanding the invention Bauele-elements are described. The hook connection 14 has one over the front edge 10 of one panel 1 extended hook hook 16 , at the free end portion of a hook projection 18 is trained, in the vertical direction to the other panel 2 protrudes. The Ha-kenlippe 16 extends in the illustration according to 2 in extension of the lower large area 22 of the panel 1 ,

In the illustration according to 2 bottom corner corner of the other panel 2 is according to the hook lip 16 stepped freely cut, so that an inner hook recess 20 is formed, in which the hook projection 18 dips. The hook recess 20 is to the left ( 2 ) through a cutter 24 bounded in the area between the front edge 10 and the hook projection 18 dips. The hook projection 18 is with sliding or slight press fit in the hook recess 20 recorded so that a reliable horizontal locking is present. For vertical alignment of the cutter sits 24 with its bottom face 26 on the top of the hook lip 16 on, leaving the panel 2 down on the panel 1 is supported. In the 2 right side surface of the cutter 24 runs at a distance to the front edge 10 ,

With such a connection, an over tooth can not be prevented because, for example, the panel 2 still opposite the panel 1 can be moved upwards. For vertical locking according to the invention is a slide assembly 28 intended. This consists essentially of a along a slotted guide 30 guided slide 32 who is from his in the 1 and 2 shown release position can be adjusted in a locking position in which the slide 32 in sections in a Stirnnut 34 on the other panel 2 dips. This locking position is in the 3 and 4 shown.

According to the sectional views in the 1 and 2 is the scenery guide 30 through one in the front edge 10 opening leadership 36 formed, which is milled above the hook connection. At a groove bottom 38 this extending in the horizontal direction guide groove 36 are by a disc cutter circular arc or concave control recesses 40 . 42 educated. According to 1 are these two tax cutouts 40 . 42 spaced apart and slightly upwards, to the spring 6 staggered. Ie. the tax cut-outs 40 . 42 are not symmetrical to the longitudinal centerline 44 the panels 1 . 2 angeord-net.

5 shows a single representation of the in the control recess 40 inserted slider 32 , Accordingly, this is designed as a slide bar whose overall length L is slightly less than the width of the panels 1 . 2 is executed. The slider 32 has an approximately rectangular basic shape with a straight locking edge 46 , The approximately parallel thereto extending other longitudinal edge of the slider 32 is as a control edge 48 with two approximately trapezoidally projecting control cam 50 . 52 executed. The geometry and relative arrangement of the control cams 50 . 52 is chosen so that these in the illustrated release position in the tax recesses 40 respectively. 42 can dip, so the slider 32 with its control edge 48 at the bottom of the groove 38 is applied. The locking edge 46 then close as per 2 about with the front edge 10 so that the swinging down of the panel 2 is not hindered for the production of the front edge lock. As shown in 1 protrudes an end section 54 of the slider 32 laterally out of the guide groove 36 out and is about as far as the end of an extended Nutunterwange 55 the groove 4 in front.

To adjust to the locking position, the end portion 54 by hand, by means of a tool or by attaching another panel to the longitudinal groove 4 in the guide groove 36 postponed. Because the slider 32 in its release position with side cheeks 56 . 57 the control cam 52 respectively. 50 at the adjacent end faces of the control recesses 40 . 42 (when using trapezoidal control cam 50 . 52 If a tangential system is created), the spool becomes 32 when moving down in 1 by sliding down the sidewalls 56 . 57 at the end edges of the control recesses 40 . 42 also offset to the right, so he with his through the locking edge 46 limited area in alignment with the guide groove 36 trained forehead groove 34 on the other panel 2 dips. If the end section 54 completely in the guide groove 36 moved, the slider has 32 his in the 3 and 4 illustrated locking position he-reaches, in which the control cam 50 . 52 with cam end faces 58 . 60 at the bottom of the groove 38 the guide groove 36 issue. The locking edge 46 with the adjoining longitudinal edge region of the slider 32 is then in the Stirnnut 34 recorded, so that a very stable vertical locking is effected.

The Release the connection by moving the panels along the front edges.

According to the invention it is preferred if the strip-shaped slide 32 made of plastic. This can be done for example by punching plate material or by injection molding. In principle, it is also conceivable, the slide 32 to process from strip material at the production station. A losing the slider 32 during transport is almost impossible, as this very reliable in the guide 36 is guided. To increase the reliability, the protruding end section 54 be colored so that the laying person is aware of when the slide 32 is in its laying position or locking position.

The width of the end groove 34 corresponds to the width (perpendicular to the plane in 5 ) of the slider 32 , so that its upper and lower large areas fed on the upper and lower side walls 62 . 64 the forehead groove 34 issue. Through this fit is in addition to the support of the face 26 the cutter 24 on the lower hook lip 16 ensures a vertical alignment, so that the emergence of an over tooth is excluded. The connection for plate-shaped components described above is superior to the solutions described above, both in terms of function as well as in terms of material and device-technical effort.

Disclosed is a connection for plate-shaped components, in particular floor panels, with a horizontal connection, by lowering a component to another, already laid Component along a front or longitudinal edge into engagement Can be brought, so that the components connected in the horizontal direction are. The connection further has a vertical lock, wherein a locking member disposed on a component in locking engagement can be brought with the other component. This is a slider from a Release position adjusted to a locking position in the a locking shoulder of the other component is engaged behind.
