Description

The invention relates to a system of constructing furniture, in particular wardrobes, cabinets, shelving and racks, as well as display windows and furniture units to meet individual needs.
Commonly known solutions of constructing furniture are characterised in that they consist of horizontal elements and vertical elements which have holes and pegs respectively at their edge joints, as well as of hinged connectors and ones usually made of metal or plastic to strengthen and reinforce the edge joints.
The furniture connector known from the description of Polish patent No 143485 , joining two load-bearing walls, is characterised in that in the recess of one load-bearing wall is a cuboid-shaped plate featuring a perpendicular cylinder-shaped element with a hole of a rectangular cross-section. In order for a furniture tie to be fixed by means of a screw, the other load-bearing has a threaded hole, as well as a threaded hole and a cylindrical hole for a furniture side wall to be fixed with two screws so that a furniture moveable board element can be seated in the triangle notches and holes formed in the plate by means of a thread. Such a connector can be used to construct only simple furniture units.
Polish patent description no 170714 presents a set of furniture constructional elements, comprising boards, frames and connectors, characterized in that the straight connector is a channel section with the side walls provided with two pairs of opposite holes between which there is a protrusion, the frames featuring notches for the protrusions to be put in, and the boards having such holes that the bolts located in the holes of the connector can be fixed. Angle, cross, and semi-cross connectors are formed by the proper and permanent joining of straight connectors. This solution makes it possible to construct various arrangements of shelves and racks, above all for children, and to make furniture units tailored to the needs of the user and the location, as well as to be easily extended without effort and any tools.
A disadvantage of this system is that it can be used to construct units of small sizes and heights because such connectors are unable to bear large loads.
The solution according to the invention described below lacks such disadvantages.
According to the invention, the idea behind the solution is that two tie elements are joined by at least one flexible connector including a line element going through two longitudinal holes and one transverse hole of each tie element, forming an F-shaped cross-section with two ends of the line element fixed to the tightening element, wherein the line element and the tightening element are inside the closed or partially open space delimited by the walls whose edges are in contact with the ties, wherein the walls are made out of a laminated composite sheet material bent along appropriate lines.
