Corner connectors for element panels, especially for furniture construction

Abstract

Corner connector for element panels, in particular for furniture construction, which is infinitely expandable horizontally and vertically in the system and has the special feature of being able to connect corner connectors and element panels without tools, characterized in that corner connectors and element panels (3,6,7) have the same profile image on the connecting edges and by pushing the element panels (3,6,7) flush on the front side onto the corner connector, a force-fitting connection is created between the corner connector and the element panels (3,6,7).

Description

[0001] Carcass furniture of conventional design has upper, lower, side or diagonal element panels.

[0002] Standard furniture connectors are typically used to connect element panels. The element panels are provided with various different holes and millings for this purpose. This assembly method cannot be installed without tools or flexibly expanded, is time-consuming, and, due to the multitude of different individual parts required for assembly, can lead to incorrect assembly, especially for non-experts.

[0003] Conventional prefabricated panels cannot be used to remedy this. Suitable prefabricated panels feature a novel profile pattern on their edges.

[0004] The invention specified in claim 1 is based on the problem of creating a tool-free, dismantable carcass furniture which, when dismantled, can be stored in a space-saving and simple manner, can be easily transported and assembled, consists of only two different components and is stable when assembled, is infinitely expandable and allows flexible, stepless carcass proportions in height, width and depth.

[0005] This problem is solved by the features listed in claim 1.

[0006] The invention ensures that the element panels are securely and force-fitted to one another when assembled using corner connectors. The corner connectors can be removed without tools just as quickly as they were previously installed.

[0007] The system kit is self-explanatory for any installer without an assembly diagram or written instructions, as there are only two different components and the connection of the corner connector and the element panels through the position of the grooves or rebates in the panel edges clearly specifies the installation direction of the corner connector with its elevations and webs over the front edge of the panels and therefore does not allow for any alternative installation option.

[0008] Due to the profile design of the corner connector and the matching profile design of the edges of the element panels, when the corner connector is pushed onto the profiled edge of the element panels, a force-locking connection is created which can only be released by pushing the corner connector out again at the front.

[0009] Additional fastenings to the corner connector are not necessary, as the corner connector remains in position due to the frictional resistance between the corner connector and the element panels. The corner connector can also be glued in place if permanent fixation is desired.

[0010] Because the corner connector is inserted over the end faces of the panels, it is possible to insert the back panel of a piece of furniture or the base of a drawer into a circumferential groove on the back of the element panels, thus creating a back panel or base that is enclosed on all sides and has a stable shape.

[0011] The corner connector is installed in a time-saving and therefore cost-effective manner, simply by inserting the angle connector along the two edges of the element panels and the grooves or rebates provided for this purpose.

[0012] The use of a modular system enables the economical production of element panels by consistently maintaining the same element dimensions with a single profile pattern. At the same time, it is possible to create, modify, and expand an infinite number of cabinet shapes. By using variable element dimensions in height, width, and depth, in combination with different length profile sections for the corner connectors, countless variations of cabinet proportions can be created. Different materials and colors of element panels can be combined within a cabinet furniture piece, allowing for further flexible design variations.
