The present invention relates to the field of bed frame structures, and in particular, to a novel detachable bed frame assembly mechanism. The novel detachable bed frame assembly mechanism includes a bed frame body. The bed frame body includes an outer frame, an inner frame, and two sets of wooden strips. The outer frame is a rectangular frame including two horizontal tubes, two lateral tubes, four L-shaped iron-plate connectors, bolts, and nuts. The inner frame includes at least one horizontal connecting tube, a plurality of lateral connecting tubes, iron sheets, bolts, and nuts. The two sets of wooden strips are symmetrically disposed on the horizontal connecting tube and the horizontal tubes on both sides of the horizontal connecting tube and are parallel to the lateral tubes, to connect the horizontal connecting tube to the horizontal tubes. The invention is easy to assemble and disassemble and is safe and reliable.

This museum showcase comprises a load-bearing frame comprising tubular beams with quadrangular section connected together by at least one joint, and is characterized in that the joint comprises two flat and parallel plates, wherein each plate comprises a middle portion and at least two attachment wings, wherein the two attachment wings of each plate are respectively inserted in a first and a second of the tubular beams and fixed to them. In this way, the showcase can be designed and built in a particularly quick and easy manner. Both the beams and the joints can be made starting from extremely simple and cost-effective semi-finished products (tubes and plates, respectively), with elementary processes, basically simple cuts to the desired sizes.

A pair of connectable box carcass framework members for the fabrication of non-panel constructed furniture carcasses. They simplify the construction of a furniture carcass with a minimal of tools and skill required to produce a dimensionally square, precisely sized, box that accepts an abundance of aesthetic and functional options. They are based on a pair of mechanical fastener connectable vertical and horizontal members that have connectable zipper channels, linear rabbets for the retention of side panels, screw busses, and open channels with series of spaced orifices therein for the passage of mechanical connectors.

An outdoor unit of an air conditioner, including a cabinet including a base panel and a side panel; a compressor supported by the cabinet; a heat exchanger supported by the cabinet; and a leg frame at a lower end of the cabinet to support the cabinet. The leg frame includes: a channel including an upper flange coupled to the base panel, a lower flange installable on an installation surface, and a web connecting the upper flange with the lower flange. A first coupling portion and a second coupling portion are configured to fix one side portion of the channel to the side panel, and are positioned on opposite sides with the channel interposed therebetween.

A composed element, such as a piece of furniture, wherein the composed element comprises at least a rear wall, as well as a number of constructional parts forming a whole in which the rear wall has to be provided. The rear wall forms the rear side of the composed element and includes one or more rear wall parts. The composed element comprises seats for installing at least one of the rear wall parts, which are configured such that the rear wall part can be slid into the seats starting from the rear side of the composed element from a position differing from the final plane in which the rear wall part will be situated in the final condition.

A tool cabinet comprises a front frame; a rear frame; a door panel; a back panel; a side panel; a shelf; a top panel; a bottom panel; and a supporting leg. The tool cabinet is combined with the front frame and the rear frame thereof serving as the main body, such that the structure of combined tool cabinet is stable, the manufacturing process thereof is improved, the components thereof are properly spaced, and the tool cabinet can be disassembled easily. As the tool cabinet is combined from various components, the packaging thereof is reduced by two third, significantly reducing the transportation cost and resources consumed.

A chair (1) wherein the back rest (10) comprises two elongated connection members (11a, 11b) each provided with a hole (12a) extending along a crossing direction (T). The respective leg (20a, 20b) is provided with a first bore (21a) extending along a longitudinal direction (L) and a second bore (22a) extending along the crossing direction (T), connecting with the first bore (21a). The first bore (21a) is configured to receive a portion of the elongated connection member (11a). The corner pieces (31a, 31a′) are provided with a through-going hole (32a) being configured to be in register with the hole (12a) of the elongated member (11a) and the second bore (22a) of the leg (20a, 20b). The chair (1) further comprises a first and a second fastening arrangement (40) extending through the through-going hole (32a) and through the second bore (22a) into the hole (12a) of the elongated connection member (11a) to interconnect the back rest (10), the legs (20a, 20b) and the corner pieces (31a, 31b, 31a′). The disclosure also relates to a kit of parts configured to be assembled into a chair.
