The first panel (10) comprises a loose tongue (11), and the second panel (20) comprises, along the edge of its inner side (20a), a recess (21), complementary in shape to that of the edge with the bearing surface (15), a longitudinal assembly groove (21), complementary in shape to that of the tongue (11), and, beyond the groove (21), a bearing surface (25), recessed relative to the plane of its inner side (20a), for receiving the edge tearing surface (15). The assembly groove (21) has a bottom surface (22) and a small bearing surface (24) joined by a truncated concave ridge (27) and the loose tongue (11) has a complementary truncated ridge (17). ## Claims ### Claim 1 A furniture carcass comprising panels assembled edge to edge in a loose tongue (11) and groove (21) method and having a bottom (6) sliding into grooves (31, 32) of the panels (10, 20) in which a first (10) and a second panel (20) are assembled by the edge of the first panel (10) which abuts on an inner side (20a) of the second panel (20) to form a dihedral, A on its edge, the first panel (10c) has along its edge (10c) along the inner side (10a), a loose tongue (11) having an advanced bearing surface (15) and a locking groove (16) at a base of the tongue (11) along the inner side (10a) of the first panel (10), B the second panel (20) comprising along an edge and on its inner side (20a) a complementary groove whose shape matches that of the edge (10c) of the first panel (10) with, on the one hand, a longitudinal assembly groove (21), having a shape matching that of the tongue (11) it receives and beyond the groove (21), a bearing surface (25) standing back from a plane of its inner side (20a) for receiving the advanced bearing surface (15), and a locking groove (26) parallel to the inner side (20a) of the second panel (20) opening out into the groove (21) in a position matching that of the locking groove (16) in the first panel (10) when the two panels (10, 20) are assembled, C by assembly, the loose tongue (11) fitting into the groove (21) and the locking grooves (16, 26) complement one another to form a channel (30) receiving a locking device (5, 50) slipped into the channel (30) to secure the loose tongue (11) in the groove (21), D the locking device (5) includes: a board (52) forming a handle and an underside (520) of which is plane to form a board bearing surface on the assembled panels (10, 20), around an opening of the channel (30), a rigid blade (51) integral with the underside (520) of the board (52) and having a rod shape, rectangular in section, matching that of the channel (30) so that it can be slipped into the channel (30), an attaching tab (53) integral with the bottom (520) and terminating in a clipping nose (531) turned toward the blade (50) and designed for clipping into the groove (32) of the second panel (20) with the clipping nose (531), distant from the bottom (520) of the board (52) by a distance (d2) included between the board bearing surface of the panels (10, 20) around the opening of the channel (30) and the groove (31, 32) receiving the bottom (6), characterized in that the fastening tab (53) is in the form of a truncated pyramid the large base of which is connected under (520) the board (52) and the small base of which ends in the nose (531). ### Claim 2 (depends on 1) The furniture carcass according to claim 1, characterized in that the blade (50) is a rod shape having a rectangular cross-section with rounded edges (50a). ### Claim 3 (depends on 1) The furniture carcass according to claim 1, characterized in that a side (53d), opposite a side (53a) comprising the nose (531) of the attaching tab (53), is reinforced by a boss (532) adding to the rigidity of the link between the nose (531) and fastening tab (53). ### Claim 4 (depends on 1) The furniture carcass according to claim 1, characterized in that a side (53a) with the nose (351) is parallel to a rear side (50b) of the blade (50) and at a distance (d1) from it which is more or less equal to a thickness of the wall that exists between the channel (30) and a face of the inner side (20a). ### Claim 5 (depends on 1) The furniture carcass according to claim 1, characterized in that around the channel (30), the panels (10, 20) have recesses (41, 42) that form a recess bearing surface around the opening of the channel (30), at a distance (d2) from the grooves (31, 32) receiving the bottom (6), the distance equal to a distance between the bottom (520) of the board (52) and the nose (531). ### Claim 6 (depends on 5) The furniture carcass according to claim 5, characterized in that the board (52) is rectangular and one side (50a) of the blade (50) forms an extension of a front edge (52c) of the board, leaving a bearing strip on either side, delimited by sides (52a, 52b) of the board (52). ### Claim 7 (depends on 6) The furniture carcass according to claim 6, characterized in that the bearing strips are at least as wide as a width of the recess bearing surface to which such strip is applied, depending on the relative assembly orientation of the two panels (10, 20). ### Claim 8 (depends on 7) The furniture carcass according to claim 7, characterized in that the bearing strips are approximately as wide as the width of the recess bearing surface on the panel (10) and a face (53c, 53b) of the attaching tab (53) is perpendicular to its front side (53a) in order to contact with the inner side (10a) of the wall (10) according to the relative orientation of the assembly of the panels (10, 20). ### Claim 9 (depends on 6) The furniture carcass according to claim 6, characterized in that the board (52) ends in a raised rounded end (521) section (angle a) with respect to the bottom (520).
