Problems solved by technology

[0007] Known profiles with a rectangular or square cross-section are relatively expensive in terms of material and are correspondingly heavy
The detachable fastening method of the triangular profile that can be installed in the extension of the corner connection leads to high construction, manufacturing and assembly costs
Additional tools are required for punching or crimping the installed profile, which has a very negative effect on the installation on site

Embodiment Construction

[0030] Figure 1 shows a corner connector 5 consisting of a corner piece 6 and two fixed extensions 7 at right angles to each other and lying in the same plane. In this embodiment, the corner connector 5 is used to form a rear left corner according to FIG. 2, wherein a transverse profile 2, a longitudinal profile 3 and a vertical profile 4 are arranged along the X, Y and Z coordinate axes . The two fixing extensions 7 of the corner connector 5 have a triangular cross-section with engaging elements 18 for securely fixing the installable transverse profiles 2 and longitudinal profiles 3 . The transverse profile 2 and the longitudinal profile 3 are cut to length from triangular hollow profiles whose structure exactly matches that of the fixed extension 7 and can be fitted or engaged on the fixed extension 7 with limited play.

[0031] Firmly and substantially non-detachable fixation of the installed transverse profile 2 and longitudinal profile 3 is achieved by means of grooves 2...

Abstract

The frame has transverse and depth profiles connected via corner joints to upper and lower frames joined near the corner joints by vertical profiles. At least the transverse and depth profiles of the upper and lower frames are made of triangular hollow profile. Each corner joint has a corner part and two plug-in fittings for mounting triangular transverse and depth profiles. Vertical profiles have attachments for fixing to corner parts. The frame has transverse (2) and depth (3) profiles connected via corner joints (5) to an upper and a lower frame and vertical profiles (4) joining the upper and lower frames near the corner joints. At least the transverse profiles and the depth profiles of the upper and lower frames are made of triangular hollow profile. Each corner joint has a corner part and two plug-in fittings (7) for mounting triangular transverse and depth profiles. The vertical profiles have attachments (8) for fixing to the corner parts.

Description

technical field [0001] The invention relates to a base frame, in particular to a base frame for equipment cabinets, having transverse and longitudinal profiles connected to an upper and a lower frame by means of corner connectors, and with vertical profiles, which Connection to the upper and lower frame in the area of ​​the corner connectors. [0002] The invention is basically suitable for use in cabinets, cabinets and containers, but preferably cabinets for housing electrical and electronic equipment and components, such as LAN, computer and server cabinets. The invention can also be used for operable, in particular workshop benches, in which three beams or sides are connected to corner members at right angles to each other. Background technique [0003] DE9302769U1 discloses an equipment cabinet with guides for installation, with through holes for fixing vertical, horizontal and longitudinal beams with fastening components. The guide is arran...
