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.

Provided is an external structure configured to be attached to or detached from an electronic device having a concave portion formed on a surface of a housing, and a connection connector provided in a position of the concave portion receding from the surface of the housing, the concave portion having a cross-sectional shape enabling locking of the external structure, the external structure including a first fitting unit configured to be fitted to the connection connector.

A mounting system for mounting a lift gate on a structure is provided, the lift gate having a lift platform supported between a pair of spaced support columns. The mounting system comprises a first mounting member configured for attachment onto said structure, wherein the first mounting member includes a support protrusion for engaging an opening in a wall of a corresponding lift gate support column. The mounting system further comprises a second mounting member configured for attachment onto said structure, wherein the second mounting member includes a support protrusion for engaging an opening in a wall of a corresponding lift gate support column. When the mounting members are attached to the structure and the corresponding lift gate support columns are mounted on the support protrusions, the mounting members support the lift gate on the structure.

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 folding mattress support system replaces a conventional bed frame with rails and the box spring. The mattress support system is lighter, easier to transport, and provides more storage space beneath the mattress. The mattress support system includes bed frame assemblies, central connecting bars, edge attachments, headboard attachments and a bed skirt. Leg supports fold out from the bed frame assemblies, which themselves unfold in the middle. Central connecting bars connect inner side edges of the bed frame assemblies. Plastic edge attachments are attached at outer corners of the bed frame assemblies and hold a bed skirt taut when the frame assemblies are standing on extended leg supports. A mattress is then placed on top of the assembled mattress support system. Optionally, metal edge attachments at the head corners hold both the bed skirt and a headboard. Alternatively, headboard attachments protrude from under the bed skirt and support a headboard.

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 spacer adapted to be used with cabinet installation includes a spacer block connected to a support wall. The spacer block is adapted to be positioned so that the support wall is placed over a wall edge and the spacer block is placed between a pair of cabinet walls.

An assembly structure for an assembly member includes a locking protrusion disposed in a protruding manner on a speedometer ring portion of a decorative ring and a locking portion formed in a meter case and configured to lock the locking protrusion. The locking protrusion includes a substantially quadrangular prismatic portion, which is disposed in a hanging manner from the speedometer ring portion, and a locking depression, which is formed by means of notching across two adjacent lateral faces of the substantially quadrangular prismatic portion. The locking portion includes a locking wall, which extends inward from an opening edge of a locking hole that is formed in the meter case, and a locking protruding part, which is disposed in a protruding manner on the locking wall and which engages with the locking depression.

An extendable and retractable column which is formed from at least three linked sections or chains. The linked sections include a plurality of individual segments linked end to end. As the linked segments are extended, each of the individual segments of the linked chains engage individual segments of adjacent linked sections to form a column. As the linked sections are retracted, each of the individual segments of the linked sections disengage from the individual segment of the adjacent linked sections and the individual linked sections may be rolled up into a multi-sided form for compact storage.

A driving force transmission unit includes a first coupling, a second coupling, and a first rotary shaft. The first coupling includes a first contact portion and a hole, the inner circumferential surface of which has a rounded rectangular shape in cross section including a circular arc portion. The second coupling includes a second contact portion disposed at a position facing the first contact portion to contact the first contact portion along a direction of rotation of the second coupling. The first rotary shaft is connected to the first coupling and includes a shaft portion, an outer circumferential surface which has a rounded rectangular shape in cross section including a circular arc portion inserted into the hole of the first coupling.
