Profiled element for establishing tongue and groove connections, and laminate thereof

Abstract

The invention relates to profiled elements (P) for the interior and exterior mounting, each element comprising at its lateral edges connection portions ( 10, 20 ) for establishing tongue and groove connections, and the connection portions ( 10, 20 ) comprising co-ordinated bulges ( 14, 24, 25 ) and recesses ( 12, 13, 22, 23 ) to provide a multi-level engaging of the tongue ( 10 ) into the groove ( 20 ). At least the groove ( 20 ) is comprising at each of its bottom and top sides (U, O) two bulges ( 24, 25 ) and/or recesses. The bulges ( 14, 24, 25 ) and recesses ( 12, 13, 22, 23 ) are symmetrically formed towards the transverse axis of the profiled element. The tongue ( 20 ) comprises a notch, in particular a V-shaped groove ( 27 ), which takes up the bolt head of a mounting screw (M). Thus the elements can be assembled and installed more easily and fast. Laminates or composites made of that elements are very flexible to compensate material-conditioned dimension changes caused by varying temperature and dampness.

1 . Profiled element for the interior and exterior mounting, the profiled element comprising at its lateral edges connection portions for establishing tongue and groove connections with adjacent profiled elements, each profiled element comprising at one of its lateral edges at least one tongue and at the opposite lateral edge comprising at least one groove, wherein the tongue of the adjacent profiled element being insertable, and the connection portions each with a bottom side and a top side comprising coordinated bulges and recesses to provide a multi-level engaging of the tongue into the groove, and at least one of the connection portions is comprising at each of its bottom and top sides at least two bulges and/or recesses, 
 characterized in that    the bulges and recesses at the bottom side and at the top side are symmetrically formed towards the transverse axis of the profiled element, and that the tongue comprises at its bottom and top side a notch, in particular a V-shaped groove, which takes up the bolt head of a mounting screw.    
   
   
       2 . Profiled element as cited in  claim 1 , characterized in that the V-shaped groove is meeting a straight slot.  
   
   
       3 . Profiled element as cited in  claim 1 , characterized in that the profiled element is comprising at least inwardly a symmetrically designed core portion, and that the bulges and recesses at the bottom side and at the top side are symmetrically formed towards the transverse axis of the profiled element and that at least the tongue is having faces tapering off with rising angles towards the direction of insertion being more plain than the decent angles towards the opposite direction.  
   
   
       4 . Profiled element as cited in  claim 1 , characterized in that the entire profiled element is symmetrically designed and is comprising two equal surfaces.  
   
   
       5 . Profiled element as cited in  claim 1 , characterized in that the profiled element is inwardly comprising a symmetrically designed core portion, but is outwardly comprising two different surfaces.  
   
   
       6 . Profiled element as cited in  claim 1 , characterized in that the recesses of the tongue and the recesses of the groove are comprising two faces tapering off and being slopingly truncated, thus the faces at least in the snap-in position are lying against to each other and are directly contacting each other.  
   
   
       7 . Profiled element as cited in  claim 1 , characterized in that the tongue comprises a cone end having a longitudinal slot, whereby the tongue for the insertion into the groove becomes resilient snapable within at least two-stages.  
   
   
       8 . Profiled element as cited in  claim 1 , characterized in that the bulges of the groove and/or of the tongue comprise compressible desired dents.  
   
   
       9 . Profiled element as cited in  claim 1 , characterized in that when the tongue is totally inserted into the groove comprises a remaining excavation and/or a remaining gap joint between the profiled elements.  
   
   
       10 . Profiled element as cited in  claim 1 , characterized in that the profiled element is a prolate profiled blank or a rectangular, in particular quadratic, profiled plate.  
   
   
       11 . Tongue and groove connection of profiled elements for the interior and exterior mounting, the profiled elements having at their lateral edges attached thereto connecting portions, each profiled element comprising at one of its lateral edges at least one tongue and at the opposite lateral edge comprising at least one groove, thus the tongue of the adjacent profiled element being insertable therein, and the connecting portions each comprising a bottom side and a top side with co-ordinated bulges and recesses to provide a multi-level engaging of the tongue into the groove, and at least one of the connecting portions is comprising at each of its bottom and top sides at least two bulges and/or recesses, 
 characterized in that    the bulges and recesses at the bottom side and at the top side are symmetrically formed towards the transverse axis of the profiled element, and that the tongue comprises at its bottom and top side a recess, in particular a V-shaped groove, which takes up the bolt head of an mounting screw.    
   
   
       12 . Laminate of profiled elements, in particular a decking profile laminate, having profiled elements for the interior and exterior mounting, the profiled elements having at their lateral edges designed connecting portions for establishing a tongue and groove connection with adjacent profiled elements, each profiled element comprising at one of its lateral edges at least one tongue and at the opposite lateral edge having at least one groove, thus the tongue of the adjacent profiled element being insertable therein, and the connecting portions each comprising a bottom side and a top side with co-ordinated bulges and recesses to provide a multi-level engaging of the tongue into the groove, and at least one of the connecting portions is comprising at each of its bottom and top sides at least two bulges and/or recesses, 
 characterized in that    the bulges and recesses at the bottom side and at the top side are symmetrically formed towards the transverse axis of the profiled element, and that the tongue comprises at its bottom and top side a recess, in particular a V-shaped groove, which takes up the bolt head of an mounting screw.
