The present invention provides a combining and expanding structure of a layered frame, especially to provide a design of a combining hook of a layer plate of the layered frame for allowing the layered frame to be easily combined in a coupled or multiplied format; a combining part of the combining hook is designed to be formed in various structural statuses with respect to the layer plate made of different materials and formed in different statuses, so that the combining hook is able to be respectively combined at four distal corner parts of a metal-state layer plate, an iron-rod layer plate, a wooden-state layer plate or a glass-state layer plate, a buckling hook part of the combining hook is designed in a half-thickness status, so that the combining hooks disposed at the left and the right distal corner parts of the layer plate are able to be oppositely arranged.

The present invention provides a clip-shelf fixer, comprising a pipe clip with two side clip-claws on both sides, which a bayonet is formed between the ends of the two side clip-claws and a pipe cavity is formed between the two side clip-claws, wherein the two side clip-claws on both sides are provided with a first portion of the two side clip-claws and a second portion of the two side clip-claws along the axial direction of the pipe cavity; there is an gap between the first portion and the second portion of the two side clip-claws, which is compatible with mesh wires of mesh plate, and at the end of the gap a first mesh wire connection part perpendicular to the axial direction of the pipe cavity is provided; the first mesh wire connection part is provided with a first mesh wire cavity, and the first mesh wire cavity is connected with the pipe cavity to form an integral pipe and mesh wire connection cavity. The present invention can connect the supporting pipe with the mesh plate steel wire intersecting with it, and each supporting pipe can be connected with the matched mesh plate on the support pipe, so as to avoid missing connection; and the overall structure of the clip-shelf fixer can be further strengthened by combining with the parallel steel wire connection structure.

A retaining system for joints without utilising welds, screws or any other additional element or accessory, consisting in the making of a closing or locking mechanism, by means of a tab-slot configuration, using only the structure proper of the sections which are the object of the jointing, according to a first section (A) on which the cutting or machining that gives rise to the tabs and an embedment gap is made and a second section (B) that houses the slots and has to fit in the said embedment gap of section (A). Finally, the system is supplemented with the addition of tools that make it possible to release the system, thus making the joint demountable.

Provided is prefabricated furniture and, more particularly, to a prefabricated shelf (angle) having assembly holes and assembly protrusions for assembling frames together, the frames being more firmly assembled as a pressing protrusion portion protrudes from a narrow portion of an assembly hole so that an assembly protrusion is forcibly fitted by the pressing protrusion part. The prefabricated shelf includes a first frame in which a pair of assembly holes, each having a wide portion and a narrow portion, are arranged symmetrically, and a second frame in which a pair of assembly protrusions, corresponding to the assembly holes and each protruding to fit into the narrow portion, are arranged symmetrically, wherein the narrow portion includes a pressing protrusion portion configured to protrude from a first end thereof and press the assembly protrusion to a second side thereof to force the assembly protrusion into place.

A furniture frame is provided that includes a plurality of frame members and a socket coupled to at least one of the plurality of frame members. The socket may include a plurality of walls arranged about a central axis and enclosing the central axis. The frame may further include a leg configured to be removably inserted into the socket. A first portion of the leg that is configured to be inserted into the socket may include walls having approximately a first thickness, and a second portion of the leg that is not configured to be inserted into the socket may include walls having approximately a second thickness that is twice as large as the first thickness. The frame members, socket, and leg may comprise metal.

Connecting element for a piece of furniture for connecting a first furniture component, for example a side wall, to a second furniture component extending obliquely to the first furniture component, for example a shelf support or a shelf, without additional material-locking means and without additional fastening means, including: a first functional section for a first snap-in device which, in the assembled state, forms a first form-fit of the connecting element with the first furniture component, a second functional section for a second snap-in device which, in the assembled state, forms a second form fit of the connecting element with the second furniture component, a receiving area in which, in the assembled state, a section of the second furniture component is received, and a third functional section for a third snap-in device which, in the assembled state, forms a third form fit of the connecting element with a cladding element which covers the receiving area at least partially, preferably completely, towards a visible side of the piece of furniture, and/or a fourth functional section for a fourth snap-in device which, in the assembled state, fixes a rear wall of the piece of furniture.

A seating furniture chassis comprises a base body, a fastener arranged on the base body and comprising a fastening element and a spring element that exerts a spring force on the fastening element, and at least one side part releasably fastenable to the fastener, wherein the fastening element is moved counter to the spring force upon fastening of the side part to the fastener.
