The locking blocks can be made to engage as a lock with corresponding locking bodies on another panel board (2) by sliding along the edges to be connected. An independent claim is also included for a method for connecting two rectangular panel boards.

Description

The The invention relates to a connection for panel panels according to the preamble of claim 1

Such compounds allow the glueless laying of floor elements. In the EP 0 698 162 B1 a connection is shown, in which along the mutually to be joined end faces of the panels a tongue and groove connection is designed with integrated locking elements. To facilitate the laying of the panels, the connection is made with a game, so that a simple movement of the panels along the longitudinal edges is possible.

The WO 97/47834 A1 discloses a compound in which the floor panels can be connected by planar displacement or angle. at this construction, the lower groove cheek is extended beyond the parting plane and with a locking projection provided in a locking recess dips.

In the DE 199 62 830 C2 an improved connection is disclosed in which in addition to a conventional tongue and groove connection a separate locking pin is provided, which cooperates for locking with a locking recess.

• 1. Infolge des Plattenaufbaus herrscht in den Oberflächen eine Spannung, die sich durch den symetrischen Aufbau die Waage hält. Durch einen Einschnitt senkrecht zur Kantenebene wie bei einer Nut, und besonders bei einer verlängerten Nutwange, hat diese die Tendenz, sich nach außen, d. h., senkrecht zur Paneelebene zu verformen, da die Kräftesymetrie gestört ist. Dies hat zur Folge, dass innerhalb kurzer Zeit die Spannkraft auf die Riegelflächen abnimmt.
• 2. Es ist bekannt, dass der Werkstoff HDF oder MDF unabhängig von Punkt 1. zeitabhängige Materialermüdungen bei derartigen Belastungen aufweist.
• 3. Infolge von Punkt 1. und 2. sinkt, bei Zugbelastungen parallel zur Nutzebene die beim jahreszeitlichen Klimawechsel unvermeidbar sind, die Auszugfestigkeit der Verbindung. Die geneigten Riegelflächen lenken bei der Zugbelastung die Nutwange mit der stark reduzierten Spannkraft auf die Riegelflächen mehr oder weniger ungehindert aus. Die Folge sind offene Stoßfugen in der Nutzfläche.

The fixation takes place in these known compounds in the vertical direction to the plane of use by the tongue and groove connection. Parallel to the plane of use, the fixation in the previous compounds is usually carried out by an interlocking of locking pins and locking recesses continuously at the edges to be joined. One of these locking elements, the latch recess, is always mounted in the groove cheek behind the panel edge or in the extension of the groove cheek. The locking pin is integrated in the underside of the spring. In order to allow a planar joining of two panel elements, the lower groove cheek must deflect and the adjoining locking surfaces must be inclined relative to the plane of use. After assembly holds the rückfedernde groove cheek under tension the connection and thus the butt joints in the use plane closed. This resilient groove cheek is comparable to a one-sided clamped carrier. The one-sided clamped carrier in this case has the following disadvantages:

• 1. As a result of the plate structure prevails in the surfaces of a voltage that holds the balance by the symmetrical structure. By an incision perpendicular to the edge plane as in a groove, and especially with an elongated groove cheek, this has a tendency to deform outwards, ie, perpendicular to the panel plane, since the force symmetry is disturbed. As a result, the clamping force on the locking surfaces decreases within a short time.
• 2. It is known that the material HDF or MDF regardless of point 1 has time-dependent material fatigue under such loads.
• 3. As a result of points 1. and 2. decreases, with tensile loads parallel to the use level that are unavoidable in the seasonal climate change, the pull-out strength of the compound. The inclined locking surfaces deflect the groove cheek with the greatly reduced clamping force on the locking surfaces more or less unhindered during the tensile load. The result is open joints in the floor space.

the across from the object of the invention is to provide a connection which ensures a reliable locking with a simple structure. Furthermore, a method is to be created which is a simplified one Laying the panel panels allows.

These Tasks are regarding the connection through the feature combination of the patent claim 1 and with regard to the method by the Feature combination of claim 13 solved.

According to the invention, this takes place Lock by moving along the edge to be joined the two plate panels such that the valve blocks and formed on the other plate panel locking body each other engage behind and thus lock in the horizontal direction. The tongue and groove connection is preferably in a conventional manner formed without play, wherein the displacement by means of a punching block he follows.

at a preferred solution the invention, the locking body are offset by about a pitch to the lock blocks at the respective longitudinal edges the floor panels arranged so that the lock by moving the panels by a maximum of one division or by the necessary locking depth the transverse edges takes place.

Of the Distance between two adjacent lock blocks is a bit bigger than the length of a associated locking body on the other panel, allowing for laying the locking body in the gap between two locking blocks used and the locking can then be carried out by longitudinal displacement.

It becomes according to the invention Preferably, when the width of the locking blocks and body is chosen so that they only along their locking surfaces lie against each other and back to the adjacent end face the other plate panel are spaced apart.

The Production of the panel panels is particularly simple if the locking blocks and body formed rectangular are, in which case preferably the locking surfaces perpendicular to Locking direction to run.

According to the invention Connection at the two other edges, preferably at the shorter end faces so designed that these by horizontal displacement with each other can be brought into engagement, so that then the lock along the longitudinal edge and can be done in one operation.

The Length of the Locking block is preferably ≤ the allowable wall distance to Plattenpaneelquerkante executed so that this wall distance can be taken into account during installation. there For example, it is particularly preferred if the interlock block length ≥ half Wall distance is.

The Locking blocks and bodies used in the invention are preferably elongated lower groove cheek or on a bottom side inside extending extension a lower spring surface educated.

at an embodiment The invention relates to the surfaces the locking blocks and body in locked state approximately in contact with adjacent horizontal surfaces of the each other panel panel.

The inventive method allows a very effective Laying the panel panels, as these initially along their longitudinal edges on the Tongue / spring connection are interconnected, the locking body exactly between the locking blocks are arranged. After inserting the spring into the groove, the two panel panels then moved along the longitudinal edges, so that the locking blocks and locking body to reach each other. By this longitudinal displacement is the shifted Plattenpaneel then also frontally with an adjacent third Plattenpaneel connected.

at the conventional one solutions the locking is done frontally and longitudinally by two separate Operations.
