Abstract

Composed element, with at least two wood-based panel-shaped elements; wherein said panel-shaped elements can be coupled to each other at an angle and with a miter joint by means of a locking tongue and groove connection; wherein the tongue consists of a split tongue, with thus at least a first tongue portion and a second tongue portion, as well as a slit situated there between; characterized in that said slit, seen in cross-section, globally extends according to a direction which deviates from the direction of the center line of the panel-shaped element on which the tongue is provided.

Claims (23)

1. Composed element, which comprises at least two panel-shaped elements, each with respective panel surfaces wherein for each panel-shaped element a center line is defined centrally between the two panel surfaces of that panel-shaped element;

wherein said panel-shaped elements can be coupled to each other at an angle by means of a locking tongue and groove connection and thereby respectively from an inner corner and outer corner, wherein the inner corner and outer corner define a theoretical miter line;

wherein said locking tongue and groove connection respectively is substantially formed of a tongue on one of said panel-shaped elements, of a groove on another of said panel-shaped elements, and of locking elements provided on said tongue and groove;

wherein, seen in cross-section, the panel surface of each panel-shaped element at the side of the formed outer corner extends up to a distance from said outer corner which is smaller than three quarters of the panel thickness of the panel-shaped element to which it is coupled.

2. The composed element of claim 1 , wherein the panel surface of each panel-shaped element at the side of the formed outer corner extends at least up to the center line of the panel-shaped element to which it is coupled.

3. The composed element of claim 1 or 2 , wherein the panel surface at the side of the outer corner of the panel shaped element having the tongue continues up to a distance from said outer corner, wherein said distance is smaller than half of the panel thickness of the panel-shaped element with the groove to which it is coupled.

4. The composed element of claim 1 , wherein the panel surface of each panel-shaped element at the side of the formed outer corner extends up to a distance from said outer corner, wherein said distance is smaller than one quarter of the panel-shaped element to which it is coupled.

5. The composed element of claim 1 , wherein said outer corner is finished by means of a masking strip.

6. The composed element of claim 5 , wherein said masking strip is chosen from the list consisting of a laminate strip and an ABS strip.

7. The composed element of claim 1 , wherein said outer corner comprises a separate corner element.

8. The composed element of claim 1 , wherein said panel-shaped elements ( 2 a , 2 b ), in respect to the material from which they are manufactured, show one or more of said characteristics:

the panel-shaped elements substantially consist of a basic board formed of solid wood;

the panel-shaped elements substantially consist of a basic board formed of a wood-based pressed board;

the panel-shaped elements substantially consist of a basic board formed of wood fibers, more particularly MDF or HDF;

the panel-shaped elements substantially consist of a basic board formed of particle board;

the panel-shaped elements are formed of multi-layered and/or multi-part board;

the panel-shaped elements are formed of melaminated board;

the panel-shaped elements comprise a lightweight board, possibly with edges from another material;

the panel-shaped elements are constructed as a hollow board or as a board provided with cavities, for example, with a honeycomb core, possibly with edges from another material;

the panel-shaped elements are constructed of a basic board with a covering, more particularly a covering of synthetic material or textile.

9. The composed element of claim 1 , wherein said locking tongue and groove connection comprises a contact surface formed by an insert, wherein said insert is provided in an edge of one of the panel-shaped elements.

10. The composed element of claim 1 , wherein said locking tongue and groove connection comprises a locking element formed by an insert, wherein said insert is provided in an edge of one of the panel-shaped elements.

11. The composed element of claim 9 or 10 , wherein said insert consists of a strip which is movable and cooperates with said tongue or groove.
