Abstract
A frame composed of horizontal and vertical frame members that form front and back frames, the frames being joined at their corners using depth struts. The invention achieves a simple construction by designing the horizontal and vertical frame members as extruded sections with continuous integral or molded-in fastening grooves and screw sockets, by designing the depth struts as angle sections whose sides together form a right angle and by using fastening screws to screw the frame members meeting at the corners to the sides of the depth struts.
Claims17
In a rack having horizontal frame legs and vertical frame legs forming a front frame and a rear frame, wherein the frames are connected with each other by depth struts in corner areas of the frames, the improvement comprising:
- the horizontal frame legs (11-14) and the vertical frame legs (15-18) of the front frame (32) and the rear frame (33) each formed as an extruded profiled section with a continuous fastening groove (35, 36) and two continuous screw sockets (24, 25);
- the depth struts (19, 20, 21, 22) formed as L-shaped profiled sections with two plate-shaped legs (28, 29), each of the depth struts (19, 20, 21, 22) extending entirely between the front frame (32) and the rear frame;
- and
- the frame legs (11, 12;
- 12, 13;
- 13, 14 or 15, 16;
- 16, 17;
- 17, 18;
- 18, 15) meeting each other at the corner areas bolted together with the plate-shaped legs (28, 29) of the depth struts (19 to 22) by fastening screws (26, 27);
- and
- a plurality of corresponding corner pieces (30) covering the depth struts (19 to 22) at the corner areas, and each of the corner pieces (30) having a triangular cross section and filling a space between the plate-shaped legs (28, 29) of the depth struts (19 to 22).
In a rack having horizontal frame legs and vertical frame legs forming a front frame and a rear frame, wherein the frames are connected with each other by depth struts in corner areas of the frames, the improvement comprising:

- the depth struts (19, 20, 21, 22) formed as L-shaped profiled sections with two plate-shaped legs (28, 29), each of the depth struts (19, 20, 21, 22) extending entirely between the front frame (32) and the rear frame;
- and
- the frame legs (11, 12;
- 12, 13;
- 13, 14 or 15, 16;
- 16, 17;
- 17, 18;
- 18, 15) meeting each other at the corner areas bolted together with the plate-shaped legs (28, 29) of the depth struts (19 to 22) by fastening screws (26, 27);
- and
- the plate-shaped legs (28, 29) of the depth struts (19 to 22) and one of a plurality of corner pieces (30) and a plurality of corner strips ending flush with a plurality of adjoining narrow exterior sides of the front frame (32) and the rear frame (33).
