Panel and fastening system for panels

A fastening system for panels comprising:

• holding profiles provided on at least a first pair of opposite first and second sides of a first panel, said holding profiles being complementary to one another so as to allow one of said sides of said first panel to be connected to an opposite side of a second panel of identical construction to the first panel, said holding profiles further comprising:
• a first profile having a projection, said projection having an underside defining a convex surface and an upper side having a bevel at a free end thereof;
• and
• a second profile complementary to said first profile and having a recess defined on a lower edge thereof by a lower wall having a concave surface therein;
• said first profile and said second profile each forming elements of an articulating joint which, when joined with a complementary profile of an adjacent panel of like construction with a top face of said adjacent panel lying in a common plane with a top face of said first panel, enable bidirectional rotation of said panels about a pivot axis that is parallel to said first pair of opposite sides of said panel.

A rectangular floor panel, comprising:

• a joint projection edge provided on a first edge of the panel, complementary to and adapted to project into a joint recess edge of an adjacent panel of the same structure to form a common joint, the joint projection edges comprising a joint projection having a single convex curvature on a lower portion thereof;
• a joint recess edge provided on a second edge of the panel opposite said first edges, complementary to and adapted to receive a joint projection of an adjacent panel of the same structure to form a common joint, the joint recess edge comprising a joint recess having a single concave curvature on a lower portion thereof;
• said first and second edges being adapted to enable bidirectional rotation of adjacent, joined panels from a coplanar position;
• a first hook element provided on a third edge of the panel, complementary to and adapted to engage a second hook element of an adjacent panel of the same structure to form a common joint;
• and
• a second hook element provided on a fourth edge of the panel, complementary to and adapted to engage a first hook element of an adjacent panel of the same structure to form a common joint.

A rectangular floor panel, comprising:

• a first hook element provided on a first edge of the panel, complementary to and adapted to engage a second hook element of an adjacent panel of the same structure to form a common joint;
• a second hook element provided on a second edge of the panel opposite said first edge, complementary to and adapted to engage a first hook element of an adjacent panel of the same structure to form a common joint;
• and
• complementary holding profiles on a third edge and a fourth edge of the panel, said complementary holding profiles being adapted to enable bidirectional rotation of adjacent, joined panels from a coplanar position;
• each of said first and second hook elements further comprising a holding surface, each said holding surface being oriented such that when said first hook element and said second hook element of adjacent panels are engaged with one another, said holding surfaces engage one another so as to prevent the creation of gaps between a top face of each of said adjacent panels at their adjacent first and second edges.
