ATTACHMENT ASSEMBLY OF RACK STRUCTURE ELEMENTS Russian patent published in 2017 - IPC A47B57/08 

FIELD: construction.

SUBSTANCE: attachment assembly of rack structure elements includes a vertical hollow rack, the adjacent faces of which form an angle. On the edge formed by adjacent faces a through groove is made. The end part of the rack structure element connected with the vertical rack, made with a bending on a butt, and the fixing element comprising the rod sections of different length and the thrust element therebetween are installed in the groove. The end part with the bending is pressed to the vertical walls of the groove, and fixing element is installed so that its rod sections are pressed against the inner surfaces of the end part of the rack structure element and its bending, as well as to the internal surfaces of the adjacent rack faces. The groove height is made larger than the size of the fixing element section from its lower end to the upper supporting surface of the thrust element, but smaller than the size of the fixing element section from its upper end to the lower supporting surface of the thrust element.

EFFECT: improving the reliability of the attachment assembly.
