Abstract

Assemblable elements for the construction of furniture are specified, whereby coupling elements (1) made of metal or plastic or wood serve as corner elements and form corners that are chamfered by 45 ° and rectangularly arranged pins (2) and projections (5) as supports for the Have plates in the interior of the bevelled corners (3), with through openings in the bevelled corners (3) for fastening the coupling elements (1) to vertical columns (4) by means of the screw bolts (23) below the projections (5). There are also frames and tubular profiles (7) for the pegs (2), the furniture being constructed by spacing the frames one above the other and on the corner elements in the corners on vertical columns made of wood, methacrylate or another material are to be fastened.

Description

The invention relates to novel elements for assembling furniture of any kind - such as of tables, chairs, shelves, showcases, mobile tables for TV sets, loungers, beds etc. - and in particular on novel coupling elements that form the corner elements as injection parts or parts made of metal or plastic and possibly made of wood, their ends being straight to each other Angle lie and have projections for coupling to tubular profiles, which represent the front, rear and side long beams of the furniture to be built and the projections are used under pressure in the profiles, so that the furniture is always assembled in the same way. Compared to all previously known proposals in the relevant field, the advantages according to the invention consist in the lighter and cheaper production of the furniture unit and consequently in the lower selling price of the same.

The injection parts have a 45 ° beveled corner in their central area with an overhanging projection for supporting and / or fastening the table, seat or shelf panels, while they support the support columns of the furniture in their end areas, thereby forming the overall assembly knot of the furniture becomes.

The vertical columns supporting the whole and supporting the different frames can be made of methacrylate, Wood or any other suitable material, their height dimension is variable according to the respective furniture and the injection elbows of all superimposed frames are fastened by screws from the inner section of the injection parts and, depending on the type of furniture, horizontal, vertical, hollow or with locking plates, with mattresses or upholstered frames and in general-all necessary accessories can be used to complete the piece of furniture.

For the construction of shelves and showcases, additional angle profile parts with 45 knee ends are used, whereby their central area has the required length depending on the distance between the angular columns in the furniture, which run downwards from the side parts, and horizontal, elongated, single or multiple openings in the knee ends are provided in the downwardly extending area of the angle profile, which have a lower center channel or a lower opening for attachment to the furniture with the aid of the screw bolts which are partially screwed into the vertical angle columns, so that the additional parts are coupled to the upper end and the bolts are simple The pressure should first be lightly tightened and only after the support part has been coupled to ensure that the latter is securely positioned to support the shelves.

The coupling parts to be coupled inside the showcases have an angular profile, but with the difference that the knee or arch-like sections of the ends have different lengths and configurations, and in all embodiments they can be coupled to the side parts of the furniture for independently securing them between the front and rear pillars of the side parts by fastening the bolts through the downward channels of the corresponding horizontal, elongated openings on the pillars, the corresponding bend of the knee version having the smaller length With a cut at an angle of 45 °, the door of the display case can be opened without bumping, whereas, in contrast to the corresponding front bend mentioned above, the rear bend with the greater length also makes a cut at an angle of 45 (as is usual with strips) perpendicular to Section of the front bend serves to support and hold the rear plate of the display case and the corresponding section lies between the edge and the inner plane of the vertical column, which forms the support of the furniture, the length of the central region of the support parts as well as with regard to the connecting profiles between the injection parts depending on the d em furniture to be built is changeable in all embodiments.
