Abstract

A floor element, in particular a wooden floor element, comprising a top and a bottom surface as well as a first and a second lateral side, said first side being provided with a tooth integrally formed with said floor element, said second side being provided with a groove, said tooth and said groove extend substantially over a whole length of lateral sides and are dimensioned in such a manner, that for adjacently placed floor elements the tooth of the one floor element and the groove of the other floor element mutually engage for providing a toothed engagement, and wherein said tooth starts from said top surface and is inclined over an angle situated between 20 and 70°, preferably between 35 and 55° with respect to said top surface, said tooth having a length measured as from said top surface of at least one third of the thickness of said floor element.

   BeschriivinQ 
Haakse tand- en groefverbinding Deze tand - en groefverbinding situeert zich in de houtsector, meer bepaald bij massief houten vloerdelen en parketvloeren. 



  De haakse tand - en groefverbinding wordt gemaakt door aan de ene langszijde van de plank de tand te frezen vertrekkende aan de bovenzijde van de plank en van daaruit onder 45 graden naar onder tot op 2/5de van de dikte van de plank van   onderen   gemeten. 



  Aan de andere langszijde van de plank wordt de groef gefreesd ook onder 45 graden van de bovenzijde van de plank tot op 2/5de van de dikte van de plank van onderen gemeten. 



  Met de huidige technieken is het perfect mogelijk de haakse tand - en groefverbinding te vervaardigen, we moeten dus geen beroep doen op nieuwe technieken. 



  Het is zeer eenvoudig voor een   schrijnwerker   of parketlegger om deze vloeren te plaatsen, ook een handige doe - het - zelver is in staat een vloer met de haakse tand - en groefverbinding te leggen. 



  Vanuit de huidige stand van de technieken moet iemand die een houten vloer wil leggen deze vloer verlijmen of nagelen aan een ondervloer, dit om de planken onderling niet uit elkaar te laten schuiven. Met de haakse tand - en groefverbinding is verlijmen of nagelen niet noodzakelijk omdat de verbinding er voor zorgt dat de planken aan elkaar haken en daardoor bekomt men een groter houten oppervlak dat vrij over de ondervloer kan bewegen, dit om krimpen en zwellen ten gevolge van temperatuurschommelingen van het hout toe te laten zonder dat de planken uit elkaar schuiven.

   Description
Angled tongue and groove connection This tongue and groove connection is situated in the timber sector, more specifically with solid wood flooring and parquet floors.



  The angled tongue and groove connection is made by milling the tongue on the one longitudinal side of the board starting from the top of the board and measured from there below 45 degrees down to 2 / 5th of the thickness of the board from below.



  On the other longitudinal side of the board, the groove is milled, also measured at 45 degrees from the top of the board to 2 / 5th of the thickness of the board from below.



  With the current techniques it is perfectly possible to manufacture the angled tongue and groove connection, so we do not have to rely on new techniques.



  It is very easy for a woodworker or parquet layer to install these floors, even a handy do - it - yourselfer is able to lay a floor with the angled tongue and groove connection.



  From the current state of the art, someone who wants to lay a wooden floor must glue or nail this floor to a subfloor, so that the boards do not slide apart. Gluing or nailing is not necessary with the angled tongue and groove connection, because the connection ensures that the boards hook onto each other and as a result a larger wooden surface can be moved freely over the subfloor, this due to shrinking and swelling due to temperature fluctuations of the wood without the boards sliding apart.

Claims

Claims 1) The subject of the invention is the tongue and groove connection that is milled to the board at 45 degrees.

2) The technical characteristics are.

- The different planks with the angled tongue and groove connection cannot slide apart.

- The planks with the angled tongue and groove connection can easily be processed into a wooden floor.

- It is possible to mount and dismantle the planks with the angled tongue and groove connection several times, for example when moving, without damaging them.

- The width and thickness of the boards is of no importance for the application of the angled tongue and groove connection.

- The floor made with the angled tongue and groove connection forms one connected whole after installation without the need for fixing to the substrate.
