Set of panels for floor, wall or ceiling covering

A set of panels comprising:

• a first panel having a side edge on which a first retaining profile is disposed;
• a second panel having a side edge on which a second retaining profile is disposed that can be joined to the first retaining profile;
• the first retaining profile comprising a first protruding member having a height HB−HPM1 that is smaller than the height HB of the first panel;
• and
• a first toothed part disposed at a free end of the first protruding member and having a height HB−HT1 that is larger than HB−HPM1 and smaller than HB such as to define a first channel between the first toothed part, a top surface of the first protruding member extending between the side edge and first toothed part and the side edge of the first panel;
• the first retaining profile comprising a protruding rim that extends from the side edge along the length of that side edge from a level HTOP to a level HR between HTOP and HPM1, this protruding rim as such partially extending above the first channel;
• the second retaining profile comprising a second protruding member having a height HPM2 that is smaller than the height HB of the second panel, and
• a second toothed part disposed at a free end of the second protruding member, said second toothed part configured to cooperate with the first channel, said second toothed part comprising a groove in a surface of the second toothed part facing away from the side edge of the second panel;
• a locking profile mounted to the first retaining profile, said locking profile comprising:
• a base positioned in the first channel;
• a first abutment portion extending from a first edge of the base disposed along the edge of the channel defined by the toothed part, said first abutment portion defining an abutment surface facing the first channel;
• a second abutment portion extending from a second edge of the base opposite the first edge and positioned in the channel along the side edge of the first panel, said second abutment portion comprising a rim at its free end and extending in a direction facing away from the side edge of the first panel, such that the rim of the locking profile is snapped into the groove of the second retaining profile upon joining two panels,
• wherein the locking profile is at least partially attached to the first toothed part;
• wherein said first channel and the locking profile mounted therein are configured such as to establish a first pivot positioned along the base of the locking profile;
• and wherein a surface of the first protruding member facing the base of the locking profile comprises a support section extending such that upon joining two adjacent profiles, the locking profile is rigidly clamped between the support section and the second toothed part and a second section positioned such that upon joining two adjacent profiles, a void remains present between the surface, the second toothed part and the locking profile, thereby creating the first pivot.
