Patent ID: 7892617

Claim:
Panel for surface covering comprising: a first edge provided with a first coupling means comprising a groove defined by an upper lip and a lower lip; a second opposite edge provided with a second coupling means comprising a tongue, said coupling means being designed to cooperate so as to enable coupling of two of these panels in an assembly plane; mechanical locking means integrated into at least one of said first and second coupling means which, when two panels are coupled in the assembly plane, is configured to prevent these panels from moving apart from one another in a direction perpendicular to that of said first and second edges and parallel to said assembly plane; said first and second coupling means being designed for coupling essentially without elastic deformation thereof; wherein at least one part of a surface of at least one of said first and second coupling means includes a repositionable adhesive, which is configured to create bonds between said first and second coupling means that are multiply breakable and re-bondable, wherein a breaking of said bonds on disassembly of said panels out of said assembly plane results in a click designed to indicate decoupling to a user said click being a chemical click generated by physicochemical properties of materials in contact.
