A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.

A device for attaching a guide unit to a first furniture part which is movably guided relative to a second furniture part, wherein the guide unit includes a basic unit rail disposed on the second furniture part and a motion rail disposed on the first furniture part. Two bearing portions are disposed spaced apart on a lower edge of the device, which is provided for disposal on the motion rail. Each of the bearing portions is configured on a side which faces the respective other bearing portion, such that the motion rail can be disposed between the bearing portions. At least one of the bearing portions is mounted on the device so as to be readjustable so that a position of the bearing portion is modifiable to align the first furniture part in the assembled state in a horizontal direction in relation to the motion rail.

A worktop (1) for pieces of furniture includes two slabs (3, 4) made of stone, arranged so that they are adjacent to each other at the level of corresponding head surfaces (5, 6) in order to define a work surface (2) exposed to the outside. A joining arrangement is suited to stably connect the slabs (3, 4) and includes a first bonding substance (8) interposed between the head surfaces (5, 6) and recesses (9) obtained on the head surfaces (5, 6) of each slab (3, 4), mutually facing each other and configured in such a way as to define corresponding housings completely delimited in the direction of the thickness of the slabs (3, 4), the first bonding substance (8) being spread mainly in the housings.

A joined body is formed by joining end surfaces of two joining members to each other by a friction welding. The joined body includes a hollow portion formed on at least one of the two joining members, the hollow portion being configured to have an opening at the joining face between the two joining members. The joined body also includes an annular groove portion formed on an inner circumferential surface of the hollow portion at a position separated from a joining face in an axial direction.
