Description

The present invention relates to a modular furniture connector system.

Known furniture or shelving system, for example, in the DE 20 2006 000 921 U1 or in the DE 20 2005 013 265 U1 described. In the DE 20 2006 000 921 U1 are used a plurality of plate-shaped components and a plurality of connectors for connecting the plate-shaped components, wherein each component has a plurality of fasteners and the connectors are optionally attachable to different fasteners on each plate-shaped component, so that the components in a spatial configuration to each other can be fixed. Specifically, each component has a plurality of grooves, are inserted into the angle sheets. About the angle plates several components can be attached to each other and at right angles to each other until about a cube as a furniture or shelf part is created. In addition to the actual furniture parts, the components, so the angle sheets or angle clips are used. The handling of the angle plates is difficult and these must be driven in large numbers in the grooves on the components to keep safe there. Even when assembling the components alignment and insertion of the angle clips in the grooves on the next component is difficult and time consuming.

From the DE 20 2005 013 265 U1 It is known, two furniture parts by means of a toothing, which is provided to the two furniture parts complementary to each other in the form to connect positively. To fix this connection, a longitudinal groove is provided on the two furniture parts in the region of the toothing, in which a thin and long rod is inserted, which secures the connection and fixes the two furniture parts together. In addition to the problem of precise alignment of the gearing and the longitudinal groove that must be milled on both furniture parts, the introduction of the long thin rod is a practical problem to assemble the furniture. If the furniture consists of several furniture parts, such a rod must be mounted between all furniture parts. This solution is time-consuming and difficult to carry out by the structurally necessary exact fit of the rod in the longitudinal groove.

Finally, out of the DE 20 2006 018 300 U1 a corner joint for furniture known. This corner joint works without any other means of connection, but leaves due to the so-called wood node construction only very few degrees of freedom in the assembly of the furniture corners. Partitions or shelves can not be fixed with the corner joint. If rear walls, shelves or the like are to be installed, then after the DE 20 2006 018 300 U1 (Paragraph [0002]) holes are drilled and so-called floor beams are used.
