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 locking device which includes static load spring and a locking pin for locking two components to one another, is a sequence of a first and a second elements. Each element includes a disc-shaped part, wherein two relative the centre of the disc-shaped part opposed bridging struts are arranged equally distanced from the centre and on the same side of the disc-shaped part. The elements with said struts are arranged with the disc-shaped parts parallel to one another, and wherein the first element with the struts directed towards the second element is connected with said struts to the second element, with the struts of the second element pointing away from the first element. A line between the struts of the first element is perpendicular to a line between the struts of the second element.

A delivery vehicle has separate compartments with a common sidewall. Doors that are interchangeable between the compartments close the compartments. A latching assembly between the doors and sidewall limits movement of the sidewall when only one of the doors is closed. The compartments are combined into a single compartment by moving the sidewall when the doors are open. A hinge assembly connects the doors. A contact and wiper assembly between the doors carries power and commands for the hinge 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.
