Description

description

connection

The invention relates to a connection for components, in particular for floor panels according to the preamble of claim 1.

Such a connection for floor panels is disclosed 0,098,162 Bl, for example, in EP. In the known, so-called "glueless" compound aneinanderanliegenden peripheral edges of the panels having a tongue / groove connection are executed. The lower surface for facing Pad cheek of the groove of the one panel is extended beyond the vertical parting plane, and also has at its end a locking projection which plunges into a corresponding recess of the spring of the other floor panel. In order to facilitate the laying of the panels, the connection in the engagement region of the extended groove cheek with the spring is provided with a game, so that a displacement of the panels along the longitudinal edges is possible.

In W097 / 47834 Al a generic link is shown, is prolonged in the similar to the above solution, the lower cheek of the groove of a floor panel over the vertical separation plane outside and provided with a projection which engages in an associated clamping recess of the spring. In contrast to the solution described above, the engagement between the extended groove cheek and the associated recess of the spring is designed such that a force is applied by this locking which presses the two floor panels perpendicular to the vertical plane against each other. In both solutions described above the groove / tongue connection has a dual function. Via the tongue / groove connection, the exact matching positioning of the two floor panels is guaranteed one another so that no gaps occur and supernatants and the erfordeliche laying quality is ensured on the one hand. The second function is to ensure that predetermined relative position by the frictional or positive locking between the extended groove cheek and Spring also burdens the soil or in temperature and humidity.

A problem with the known solutions is that the extended groove cheek be elastically deformed uss, to bring about the engagement between the locking elements. Under unfavorable conditions, for example in case of excessive loading of the elastic lower cheek of the groove or in a swelling caused by moisture and the influence of temperature, it may occur that result in the connection region of the lower groove cheek of the associated floor panel cracks, so that the groove cheek can no longer meet the above-described locking function. In addition, in such cracks in the groove cheek Anbindungsbe- smells the fit of the tongue / groove connection is qualitatively deteriorated, so that the required for a proper floor installation accuracy is no longer guaranteed.

In contrast, the present invention is to provide a connection for components, especially floor panels, in which with minimal expenditure on apparatuses precisely fitting relative position is ensured based on the object.

This object is achieved by a compound having the features of claim 1. According to the invention, the fit and the locking of two separate components are adopted. The fit is carried out in a conventional manner via a groove / spring connection, while the latch by a latch pin occurs, which is formed at a distance to the tongue / groove connection and thus functionally independent of it. The locking pins can be formed at the spring-side end face or on the nutseitigen end face of a floor panel.

In a preferred embodiment of the locking pin in the distance from the spring is carried out and immersed in a recess on the lower side groove cheek pad, which is not elastic, unlike the prior art. That is, in a preferred variant enforce both the spring and the locking pin, the vertical plane of separation between the components in the horizontal direction and dip respectively into corresponding recesses of the opposite device. A particular advantage of this variant is that the removal of material in relation to the initially described solutions is much lower, so that the milling process is simplified for machining the end faces.

A particularly reliable locking in ease of manufacture is obtained if the locking pin is performed with a recess in which a projection at the bottom of the lower groove cheek. The contact area between the cheek and locking pin is in this case preferably carried out as an inclined surface such that even with relatively large tolerances applying predetermined, the two components to each other is ensured to be acted upon a pretensioning force. When flat abutting components of both the longitudinal edges and the side edges of the devices with the compound of the invention are preferably performed.

In addition to the above lock the components can also be glued.

Other advantageous developments of the invention are subject matter of further dependent claims.

In the following a preferred embodiment of the invention with reference to schematic drawings is explained in detail. Show it:

1 shows the connection area of ​​two floor panels.

Fig. 2, the floor panels of FIG. 1 in the connected state, and FIG 3 is a diagram for explaining the laying operation.

The invention is explained below on the basis of a laminate floor.

Such a laminate floor is made of a plurality of floor members, of which 1 is shown only the connection portion of two adjacent floor panels 2, 4 in Fig.. Each floor panel 2, 4 egg nes laminate floor has a carrier plate 6 - also called core - which is made of high density fiber (HDF, MDF). By such a support plate 6 a good dimensional stability and high compressive strength is ensured.

The bearing surface of each floor panel 2, 4 is formed by a Gegenzuglaminat 8, which is on the lower surface of each upper floor panel applied. For special applications still Feuc tigkeits-Isolierfo- lie (not shown) are installed. By this counter zuglaminat 8, the dimensional stability of the flooring is ter increased WEI. As indicated in phantom in Figure 1, can be connected to the underside of each floor panel 2, 4 an insulating layer 11 for the structure-borne noise, may be appropriate. The insulation layer may be made of conventional Dämmateria- lien such as PU foam advertising etc. formed the.

The visible surface of the floor panels 2, 4 is formed by a decorative laminate 10 and forming a cover layer applied thereto 12th The decorative laminate 10 is provided by printing manufacturers and gives the floor an appearance that comes extremely close to the structure of natural wood floors. The cover layer 12 provides the required robustness and durability of the flooring.

In the Fig. 1 illustrated end face 14 of the floor panel 4, a rectangular groove 16 is formed, which is delimited by an upper groove cheek and a lower groove cheek 18 twentieth

The lower, distant from the groove 16 the region of the groove cheek 20 is provided with a recess 22, the depth T is greater than the depth of the groove t 16. The remaining wall thickness of the cheek of the groove 20 is so large that their elastic deformation during the joining of the panels is practically negligible. At the bottom of the groove cheek 20 a projection 24 is formed which extends in the direction towards the bearing surface of the floor panel. 4 The side faces (perpendicular to the drawing plane) of the projection 24 are formed by inclined surfaces. The end face 26 of the neighboring floor panel 2 has a corresponding structure. Accordingly, the groove protrudes from the end face 26 of spring 16 corresponding 28th The formed by the groove 16 and the spring 28 tongue / groove connection corresponds to the connection of conventional laminate floors, which are joined together, for example, only by gluing. In the area of ​​the bearing surface of the floor panel 2, a lock pin 30 is formed, which is separated from the spring 28 via a Sirnausnehmung 32nd That is, the side walls of the front recess 32 are bounded on one side by the locking pins 30 and on the other hand by the spring 28th The depth S of the frontal recess 32 is greater than the length s of the pin - that is, the groove bottom is offset from the end face 26 to the inside. By varying the depth S, the elasticity of the locking pin 30 can be adjusted so that the extraction forces for dismantling of the floor are adjustable.

The remote from the front recess 32 large surface of the locking pin 30 extends in extension of the bearing surface of the floor panel 2. At the front recess 32 facing surface of the locking pin 30 is a notch 34 is formed, which - as will be described in more detail below - into engagement with the projection 24 of the recess 22 and is engageable is formed approximately below the end face of the spring 28th

The end face of the locking pin 30 is provided with an inclined contact surface 36 which denpaneele the joining of the soil 2, 4 in cooperation with the neighboring inclined surface of the protrusion 24 facilitates.

For joining the floor panels 2, 4 runs the

Projection 24 on the ramp surface 36 and the spring 28 is immersed into the groove sixteenth In this relative position, the lower edge of the groove 20 appears turn into the front recess 32nd

With further shifting of the floor panel 4 with respect to the floor panel 2, the locking pin 30 is due to the introduced via the inclined ramp surface 36 transverse force elastically deflected downward (see dash-dotted representation in FIG. 2). The abutting surface 36 slides on the projection 24 along until the latter into the notch 32 once snapped. In this state, the lock pin 30 engages behind the projection 24, whereby the contact between these two components only along the right formed in Fig. 2 inclined surfaces is effected while the left-arranged oblique surfaces are spaced apart.

The position of the projection 24 and the notch 32 is selected so that the two end faces 14, 26 are pressed flat against each other in the locked state, so that the gap in the end face region between the two floor panels 2, 4 is minimum. The end face of the locking pin 30 is thereby spaced from the adjacent end face of the recess 22. Since the depth is greater than the length s of the spring 28 S of the front recess 32, and the bottom of the front recess 32 is at a distance from the parting plane 38 (shown in phantom in Fig. 2) predetermining end face 14 of the floor panel. 4

The alignment of the floor panels 2, 4 in Höhenrich- processing is carried out solely by the tongue / groove connection 28, 16, while the locking and pressing of the floor panels 2, 4 is carried out solely by the locking pin 30 in cooperation with the projection 24 and thus the elasticity of the locking pin 30 depends. This can be achieved by varying the depth S of the front recess 32 (indicated by dashed lines in FIG. 1) change, so that the elastic deflection of the lock pin 30 and the locking force depending on the choice of materials and the working conditions of the soil can be adapted in a simple manner.

Even if it comes under unfavorable conditions, such as overloading of the locking pin 30 to a crack in the direction indicated by reference numeral 40 range, no height offset is to be feared, because the fit between the groove 16 and spring 28 is unaffected, while most the locking forces are reduced ,

In the conventional solutions / spring connection is canceled, both the locking and the fitting between the floor panels at a cancel of the lower cheek of the groove because of the double function of the groove. The invention thus represents a significant improvement of conventional glueless compounds so that even at the highest pressures and also at the laying errors, a precise fitting of the floor is guaranteed.

The method for laying according to the invention constructed floor panels 2, 4 is explained below with reference to FIG. 3 It is assumed that, on a dot-dash lines bottom 42 already one or more floor panels 2 (4) are laid, where the latch pin 30 supporting longitudinal side of the panel is shown in Figure 3, only the spring 48 and. The newly be added floor panel 4 is also laid flat on the ground 42, and then in the X direction (arrow in Figure 3) displaced until the inclined surface 36 runs onto the projection 24th Subsequently, an impact block 44 is placed, which has an approximately L-shaped cross-section and rests with its longer leg on the upper side of the floor panel 4, during this short leg on the right in Figure 3 end surface of the floor panel, at least engages in sections, so that these short leg abuts the spring 28th

the engagement of the locking elements is brought about as shown in Figure 2 by tapping with a hammer 46 onto the impact pad 44 in direction of the already laid floor panel. 2

The orientation in the longitudinal direction of the panels is then performed by placing the impact pad 44 on the narrow side. By striking the floor element 4 along the long side of the already installed panels can be shifted to the short sides are locked to each other.

What is essential is that it allows the inventive concept, that the floor panels 2, 4 in flatness, that can be connected together without screwing. Such tightening was needed in the initially described prior art. The inventive measures thus laying can be considerably simplified, so that the installation work can be carried out even by a layman.

A particularly reliable connection of the floor panels 2, 4 to allow, may additionally be still a connection by gluing to the illustrated locking. This sizing is preferably carried out in the tongue / groove area.

Another particular advantage of the construction according to the invention in that the latch pin 30 is formed flush with the underside of the floor panels 2, 4, so that a flat contact is guaranteed. Because the tongue / groove connection and the locking are formed independently of each other, the two floor panels 2, 4 out during the locking process already exactly by the groove / spring connection. At the above-mentioned prior art, the lower cheek of the groove, which forms the locking element is simultaneously deflected elastically during the locking process so that the precision, according to the invention guide the locking operation is not possible.

Since in the inventive locking no single pan is required, it is up to the publisher whether he first joins the long sides or short sides of the floor together. In locks, which require a pivoting, the adjacent floor panels had to be initially connected to each other along the narrow sides, and then the long, consisting of several individual floor panels floorboard be pivoted into the already installed floor panels. This is much more complicated, since the aligning of such long boards is much more difficult than the up successive laying of short floor panels.

The above described embodiment of the locking pin 30 is formed on the same floor panel 2 as the spring 28th In kinematic reversal could also form the locking pin 30 at the groove 16 provided with the floor panel 4, although slightly more material removal is necessary in order to cut free the end face.

Instead of locking via inclined surfaces could be other shapes, such as rounded surfaces, vertical surfaces, etc. used. In principle, it is conceivable also to make the locking pin 30 from egg nem different material and be fixed to the panel. Disclosed is a compound for two planar components, especially floor panels, in which a groove / spring connection system is performed separately from a functional interlocks. This locking is effected by a position spaced from the tongue / groove connection locking pins a component which engages in a correspondingly formed engaging element of the other component. The compound is preferably formed both at the longitudinal edges as well as at the end edges of a rectangular component, such as a floor panel. The lock allows joining of the floor panels in flatness, ie without swinging.
