An assembled product includes at least three elements arranged in three different planes. A first element is connected perpendicular to a second element, and a third element is connected perpendicular to the second element. The assembled product includes one or more locking devices, each comprising a flexible tongue arranged in an insertion groove one of the at least three elements. The flexible tongue cooperates with a tongue groove, at an adjacent one of the at least three elements, for locking the one element and the adjacent element together. A second edge of the second element is connected to a second edge of the third element by a first of said locking devices.

A connector assembly, having an upper connector coupled to a lower connector and a gusset plate sandwiched between the upper and lower connectors. The upper and lower connectors allow for coupling to adjacent upper and lower connectors, respectively, allowing for addition of a modular unit to a pre-existing modular structure. Also, ways of coupling adjacent upper connectors and coupling of adjacent lower connectors when coupling a modular unit to a pre-existing modular structure are provided.

This utility model discloses a kind of outdoor furniture with a non-welded and quick-installed structure, including a furniture body, is characterized in that the connection of each pipe of the furniture body mentioned is realized through the interference fit between the fittings and adjacent pipes. The utility model eliminates the welding and polishing processes and simplifies the assembly process through the interference fit of the two-coupling, three-coupling and four-coupling fittings with pipes for the early stage brackets, greatly saving the labor cost and production cost.
