  • One of the designated surfaces is an upper surface 24 of tongue 17 engaging in the joined position with an upper wall 25 of groove 18. As is shown in Fig. 4 contact between these surfaces is only in a limited contact area 26 at a distance from vertical plane VP. In this embodiment, this is accomplished by lowering upper surface 24 of the tongue adjacent the vertical surface 15 or vertical plane VP, in this case by providing a notch 27 in the upper surface " 26 extending parallel to the adjacent edge. This notch 27 may be one tenth to a few tenths of a millimetre deep and the width may be approximately between a quarter and half of the length of tongue 17, thus leaving a contact area 24 of approximately half of the upper surface of the tongue remote from vertical plane VP.
  • ⁇ pressure is exerted by tongue 17 on upper wall 25 of groove 18 by urging tongue 17 upwardly due to the engagement of heel 22 of the tongue with upward wall 23 of protrusion 20 and also with a recess 29 in the upper surface of lip 19.

The same is true for contact area 26 between upper surface 24 of tongue 17 and upper wall 25 of groove 18. This may be defined by a notch or the like in the upper wall of the groove adjacent to the vertical plane VP, such that contact is only created where this notch or inclined area ends.

Cette invention concerne un ensemble de panneaux de plancher, comprenant des panneaux de plancher (1 à 4) en forme de feuille faits d'un matériau relativement souple. Lesdits panneaux de plancher sont dotés d'une pluralité de bords (5 à 8), un premier bord (7) d'un premier panneau (2) et un second bord (8) d'un second panneau (3) étant équipés d'éléments de jointure (13, 14) qui permettent de relier le premier et le second bord des deux panneaux en les mettant en prise, de préférence dans une position inclinée des panneaux, puis en faisant pivoter lesdits panneaux l'un par rapport à l'autre de façon à aligner sensiblement les surfaces supérieures (9) des deux panneaux et à les mettre en contact sur un plan vertical (VP). Le premier bord (7) est doté d'une languette (17) et le second bord (8) d'une rainure (18) conçue pour accueillir la languette afin de bloquer les panneaux sur les bords adjacents au moins dans un sens perpendiculaire au côté supérieur et dans un sens parallèle au côté supérieur mais perpendiculaire au premier et au second bord adjacents dans leur position reliée. La languette (17) et la rainure (18) sont adaptées l'une par rapport à l'autre de telle manière qu'une surface supérieure (24) de la languette est poussée contre la paroi supérieure (25) de la rainure.
