A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, the mechanical locking device includes an insertion groove at the second edge surface, a flexible tongue positioned in the insertion groove and an edge tongue including a tongue groove, the flexible tongue includes a first locking surface and a second locking surface, the first locking surface is configured to cooperate with the tongue groove for locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a first orientation, the second locking surface of the flexible tongue is configured to cooperate with the tongue groove for a locking of the first panel to the second panel in a first direction when the flexible tongue is positioned in the insertion groove in a second orientation.

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 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.

A number of magnetically assisted latch mechanisms are presented, where the latching and unlatching action is done with reduced user effort, therefore promoting speed and efficiency without sacrificing the strength of the bond of the connected components. The latching mechanisms are designed to secure panels or other similar small and large mostly flat components. The latching method is done by a rotating component that takes all the separating load once rotated into the locked position. The rotatable lock, or hammer, is also locked itself into position to prevent accidental movement by the hammer.

A set including a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, wherein the first panel includes a first edge surface and a first panel surface, the second panel includes a second edge surface and a second panel surface, the first edge surface is facing the second panel surface in a locked position of the first and the second panel, the mechanical locking device includes an edge groove at the second edge surface, a flexible tongue positioned in the edge groove, a rod-shaped element at the first edge surface and an insertion groove at the second panel surface extending from the second panel surface to the edge groove, the rod-shaped element is configured to be inserted into the insertion groove and the rod-shaped element includes a recess.

In a set of panels for an assembled product, a first panel and a second panel may be assembled with a third panel. An end surface of the third panel includes a first tongue and a second tongue. The first panel and the second panel are configured to be arranged with their respective end surfaces facing each other. A first tongue of the third panel is configured to be arranged in an edge groove of the first panel and a second tongue of the third panel is configured to be received in an edge groove of the second panel to join the panels at least in a first direction. The first panel and the second panel may be of a first panel type, and the third panel may be of a second panel type. A corner element may be connected to a side panel of an assembled product.

An expansion connector including an expandable casing, a pushing member, a compression spring, and a connecting rod. The expandable casing includes an expansion end and is in the shape of a hollow cylindrical tube provided with an axial hole and an inner wall defining the axial hole. The connecting rod includes a first end, a second end, and a stopper disposed between the first end and the second end. The pushing member, the compression spring and the connecting rod are disposed in the expandable casing; the expansion end is expandable radially outwards with respect to the axial hole; the pushing member is disposed in the axial hole and abuts against the expansion end; the pushing member includes a first male thread, and the inner wall of the expansion end includes a first female thread corresponding to the first male thread.

A shelf-supporting device for the reversible connection of a shelf with shoulders of a piece of furniture includes a main body having a movable engagement system, to which a pin is connected. The movable engagement system slides with respect to the main body between a first non-operating position, in which the pin does not protrude from the shelf, and a second operating position, in which the pin protrudes outwardly from a transverse edge of the shelf. The movable engagement system has two distinct parts, coupled together, and the connection between the slide and the pin may be an interference coupling, a shape coupling, or another type of coupling. This shelf-supporting device makes it possible to miniaturize the pin by drastically reducing its diameter, thus improving the aesthetic impact of the housing hole in the shoulders, and may be made modular by using pins of different diameters and materials.
