Abstract

Disclosed is a connection for two panels that can be connected by lowering one panel onto another, already installed panel, both panels being designed with corresponding hook-shaped elements in the area to be connected and being locked in the vertical direction by means of a spring element. The connection is designed so that it can be released by moving the panels apart in the horizontal direction.

Description

The invention relates to a connection for two panels according to the preamble of patent claim 1.

Such compounds for panels, floor elements are for example from the EP 1 650 375 B1 or the EP 1 415 056 B1 known.

Nut- / spring-like connections are along the longitudinal edges of the rectangular panels executed, which are connected by pivoting a panel to be laid in an already laid panel, the pivot axis is approximately along the longitudinal side of the already laid panel. This longitudinal connection is provided with locking means which provide locking in the horizontal and vertical directions. At the shorter end faces of the panels each push-button or hook connections are executed in the known solutions, which get along when pivoting along the longitudinal sides into engagement with each other. For vertical locking can thereby be stored in an end face portion of a panel projecting into the parting plane spring element which is moved outwardly when pivoting down the other panel from the parting plane and then snaps back in the fully pivoted state and engages behind a locking surface, so that the two panels in the vertical direction Positioned relative to each other.

Disadvantage of this solution is that the release, for example, during the laying of the floor only by moving the two panels along the transverse sides is possible.

In contrast, the invention has for its object to provide a connection for panels in which the release of the lateral connection is simplified.

This object is achieved by a connection for two panels having the features of the claim.

According to the invention the connection of two panels is designed as a push button or hook connection, wherein both panels have mutually corresponding hook elements, in which along one side of the one panel beyond a parting plane extended lower lip is formed, protrudes from a locking projection upwards to the other panel which immersed in the locked state in a locking recess on the other panel. On a panel, an elastically resilient element is arranged, which can be brought into operative engagement with a locking surface on the other panel. This element can be designed as a separate spring element or else in one piece with the panel. According to the invention, a slot is made on the extended lower lip, by which a bendability of the lower lip in terms of a simplified unlocking of the panels is effected.

Through this slot, the panels along the said edge can be solved by horizontal displacement to each other, without the elastic element must be pushed back or without the need for a shift along the relevant edge. This shifting can be very difficult or almost impossible under unfavorable laying conditions, for example in the range of a wall or the like.

In one embodiment of the invention, the slot as a vertical slot - based on the laying surface - executed. Such a vertical slot can be finished with very little effort when milling the groove profile.

Advantageously, the slot according to the invention is carried out in a multi-layer parquet, wherein then the slot can extend in a support layer to the floor down to a lower layer.

The slot is preferably arranged in the region in which, in the locked state, the support of the one panel ends on the lower lip of the already installed panel, so that the slot is just covered.

A preferred embodiment of the invention will be explained in more detail below with reference to schematic drawings. Show it:

1 a sectional view through the front of two laid panels;

2 a detail of one of the panels and

3 a single representation of the other panel.

The invention will be explained with reference to a parquet floor, which consists of a variety of parquet panels 1 . 2 is composed, wherein along the longitudinal sides of the panels, the groove / spring-like connecting elements described above are designed with horizontal and vertical locking and along the front sides a push-button connection is executed, the structure will be explained below. The parquet is as a multi-layer parquet with a top layer 4 , a middle base course 6 and a sub-layer 8th executed and is via a hook connection 10 connected by Swinging in the panel 2 along the longitudinal side, not shown, of the already installed panel 1 is brought into operative connection. For horizontal locking is in the connection shown a spring element 12 provided during the lowering of the panel 2 towards the laid panel 1 elastic from a parting plane 14 is moved out and then snaps back to perform the vertical lock.

Details of the connection will be based on the 2 and 3 explained.

The panel 1 has one above the dividing plane 14 also extending bottom side lower lip 16 in the in 2 lower area of the base course 6 and the adjacent part of the undercoat layer 8th is formed. At the freely projecting end portion of the lower lip 16 is a locking projection 18 executed, with an inclined to the horizontal hired horizontal locking surface 20 is executed. A front edge 22 of the locking projection is chamfered several times. The angle of attack of the horizontal locking surface 20 is less than 45 ° with respect to the horizontal in the illustrated embodiment.

In the transition area of the lower lip 16 to one in the parting plane 14 lying face 24 widens the lower lip 16 over a bevel 26 or rounding. In this transition area is a slot 28 formed, extending in the vertical direction of a support surface 30 the lower lip 16 up to the lower layer 8th extends. The bottom surface of this groove-like slot 28 is rounded in the illustrated embodiment.

In the face 24 is an obliquely employed to the horizontal guide groove 32 for the above spring element 12 educated. This is performed in the illustrated embodiment as an approximately U-shaped curved spring, with their short U-legs 34 (only one visible in 1 ) at the bottom of the guide groove 32 is applied. One Base 37 (perpendicular to the plane of the drawing) of the spring element 12 stands above the dividing plane 14 out of the frontal area 24 out.

The other panel is executed correspondingly and accordingly has on its underside according to 3 a locking recess 36 with a locking surface 38 executed according to the horizontal locking surface 20 is designed so that when installed ( 1 ) the two surfaces 38 . 20 lie flat against each other and thus a movement apart of the two panels 1 . 2 prevent in horizontal direction.

This locking surface 38 is at the back of one opposite the laying surface upwards (view after 3 ) offset projection 40 formed, which has a horizontal surface 42 has, in the locked state on the support surface 30 rests. The front is the projection 40 with a chamfer 44 executed, to which a Vertikalverriegelungsnut 46 followed. This is downwards by a horizontal obliquely employed vertical locking surface 48 limited, in the locked state ( 1 ) the cantilevered beveled area of the base 37 rests against the panels 1 . 2 lock along the transverse sides in the vertical direction. Here is the chamfer 44 and the transition area to the vertical locking groove 46 at a distance to the chamfer 26 the other panel 1 , The end surface areas above the locking recess 48 lie flush against each other in the locked state so that no gap is created. As in 1 visible, is the frontal area 52 of the panel 2 in the area of the base course 6 opposite the face area of the cover layer 4 slightly reset, so that in the locked state, a small gap s in the support layer 6 arises.

In conventional connections similar horizontal and vertical locking elements are provided. These can only be achieved by relative displacement of the two panels 1 . 2 Loosen perpendicular to the drawing plane. In the solution according to the invention, the two panels 1 . 2 be pulled apart in the laying plane in the horizontal direction (perpendicular to the front side), in which case the lower lip 16 due to weakening through the slot 28 in the direction of arrow according to 1 is deflected down and the two surface sections 20 . 38 slide off each other. Upon further sliding apart slides the upper surface 50 the locking projection 18 on the horizontal surface 42 until the locking action is released.

Of course, the invention with the slot 28 also be used in a two-layer parquet or a laminate floor.

Disclosed is a connection for two panels, which are connectable by lowering a panel to another, already laid panel, both panels are executed in the region to be connected with corresponding hook-shaped elements and are locked in the vertical direction by means of a spring element. The connection is designed so that it can be solved by moving the panels apart in the horizontal direction.
