Furniture carcass formed of panels which are assembled edge to edge according to a barefaced tongue and groove assembly, wherein: - a first and a second panel are assembled by placing the narrow edge of the first panel against the inside face of the second panel, thus forming a dihedron, the first panel having a first orientation and the second panel having a second orientation in the plane perpendicular to the direction of the edge of the dihedron formed by the assembly, which furniture carcass is characterised in that A. the first panel has on its narrow edge, on the edge of its inner side, a barefaced assembly tongue, leaving a forward narrow-edge bearing surface, and a locking groove at the base of the tongue along the inside face of the panel, B. the second panel has along its inside face a housing (21, 25) of a shape which is complementary to that of the narrow edge (11, 15) of the first panel, having on the one hand a longitudinal assembly groove of a shape which is complementary to that of the tongue and on the other hand an outer bearing surface beyond the groove and set back relative to the plane of the inner side of the second panel for receiving the narrow-edge bearing surface of the other panel, C. a locking groove in the second panel opening into the assembly housing in a position complementary to that of the locking groove of the first panel when the two panels (10, 20) are assembled, the barefaced tongue of the first panel entering the assembly housing of the second panel and the forward narrow-edge bearing surface of the first panel being applied against the set-back outside bearing surface of the second panel, the locking grooves (16, 26) complementing each other to form a channel which receives a locking strip, the meeting of the barefaced tongue and the assembly groove effecting blocking in the second direction and the locking strip blocking the assembly in the first direction. - a first and a second panel are assembled by placing the narrow edge of the first panel against the inside face of the second panel, thus forming a dihedron, the first panel having a first orientation and the second panel having a second orientation in the plane perpendicular to the direction of the edge of the dihedron formed by the assembly, which furniture carcass is characterised in that A. the first panel has on its narrow edge, on the edge of its inner side, a barefaced assembly tongue, leaving a forward narrow-edge bearing surface, and a locking groove at the base of the tongue along the inside face of the panel, B. the second panel has along its inside face a housing (21, 25) of a shape which is complementary to that of the narrow edge (11, 15) of the first panel, having on the one hand a longitudinal assembly groove of a shape which is complementary to that of the tongue and on the other hand an outer bearing surface beyond the groove and set back relative to the plane of the inner side of the second panel for receiving the narrow-edge bearing surface of the other panel, C. a locking groove in the second panel opening into the assembly housing in a position complementary to that of the locking groove of the first panel when the two panels (10, 20) are assembled, the barefaced tongue of the first panel entering the assembly housing of the second panel and the forward narrow-edge bearing surface of the first panel being applied against the set-back outside bearing surface of the second panel, the locking grooves (16, 26) complementing each other to form a channel which receives a locking strip, the meeting of the barefaced tongue and the assembly groove effecting blocking in the second direction and the locking strip blocking the assembly in the first direction. A. the first panel has on its narrow edge, on the edge of its inner side, a barefaced assembly tongue, leaving a forward narrow-edge bearing surface, and a locking groove at the base of the tongue along the inside face of the panel, B. the second panel has along its inside face a housing (21, 25) of a shape which is complementary to that of the narrow edge (11, 15) of the first panel, having on the one hand a longitudinal assembly groove of a shape which is complementary to that of the tongue and on the other hand an outer bearing surface beyond the groove and set back relative to the plane of the inner side of the second panel for receiving the narrow-edge bearing surface of the other panel, C. a locking groove in the second panel opening into the assembly housing in a position complementary to that of the locking groove of the first panel when the two panels (10, 20) are assembled, the barefaced tongue of the first panel entering the assembly housing of the second panel and the forward narrow-edge bearing surface of the first panel being applied against the set-back outside bearing surface of the second panel, the locking grooves (16, 26) complementing each other to form a channel which receives a locking strip, the meeting of the barefaced tongue and the assembly groove effecting blocking in the second direction and the locking strip blocking the assembly in the first direction.
