A wall hanging system by which a wall décor item such as a ledge, a frame, artwork, or the like may be mounted to and hung from a wall. The wall hanging system may include a first mounting assembly that is coupled to the wall and a second mounting assembly that is coupled to the wall décor item. The first and second mounting assemblies may be engaged to mount the wall décor item from the wall. One of the first and second mounting assemblies may include a post and the other of the first and second mounting assemblies may include a cavity. The post may be inserted into an insertion portion of the cavity and then slid to a nesting portion of the cavity to lock the first mounting assembly to the second mounting assembly.

A system is provided comprising a first furniture part (200) and a locking arrangement comprising a connector bracket (1) and a locking element (4). The first furniture part (200) comprises a recess (201) having an oblong shape comprising an insertion portion (203) and a locking portion (204), wherein the locking portion (204) along an inner wall comprises a groove (207). The connector bracket (1) comprises a base portion (2) having an extension adapted to extend along the first furniture part (200), and at least one protrusion (3) having a longitudinal extension extending transverse the extension of the base portion (2) and comprising a rim (7) extending transverse the longitudinal extension of the protrusion (3). The protrusion (3) is configured to be inserted into the insertion portion (203) and to be movable from the insertion portion (203) to the locking portion (204) by applying a force to the connector bracket (1) in a direction transverse to the longitudinal extension of the protrusion (3), whereby the rim (7) engages the groove (207). The locking element (4) being a flexible tongue (4) is integral with the connector bracket (1) and is configured to be inserted into the insertion portion (203), thereby preventing the protrusion (3) from being moved from the locking portion (204) to the insertion portion (203) and thereby releasing its engagement with the groove (207). The locking element (4) is configured to form a safety lock adapted for acting against a portion of an envelope surface of the protrusion (3) facing the insertion portion (203) of the recess (201). Also, a connector bracket and the use of such connector bracket is disclosed.

A set including a first element with a cylindrical shaped part, a second element having a cylindrical shaped groove with a circular opening in an outer surface of the second element, and a mechanical locking device. The mechanical locking device includes a tongue groove, a displacement groove and a flexible tongue in the displacement groove, and is configured to lock the cylindrical shaped part to the cylindrical shaped groove. The flexible tongue is configured to cooperate with the tongue groove for locking the cylindrical shaped part to the cylindrical shaped groove. The flexible tongue is configured to be reshaped and displaced in the displacement groove during locking, and spring back to a locked position. The flexible tongue is configured to exert a spring force on the tongue groove in the locked position.

The recessed-key panel interlocking device is intended to provide a mechanical joint that can connect two panels using a single fastening key. Accordingly, the device connects two panels by interlocking uniform gaps and fingers that have been formed on the edges of each panel, by a small cylindrical key that holds them together. To accomplish this, a channel that can hold the key is formed along the edge region of both panels when the panels are oriented normally to one another. Further, when the panels are interlocked, the key is completely recessed within the panel material. Furthermore, while the panel edges that form the joint must be uniformly rectilinear and meet at right angles at the joint itself, beyond the joint they can assume any shape and bend to any angle, so that parts joined by the joint do not have to be panel-shaped or perpendicular to each other overall.
