Embodiment Construction

[0029] figure 1 A preferred embodiment of the present invention is shown. In this embodiment, the mounting rail 5 is provided by the bottom groove 25 , wherein the mounting rail 5 is formed by two opposing frame pieces of the bottom groove 25 . The two frame parts of the bottom groove 25 which provide the mounting rail 5 are connected to each other by two other frame parts arranged perpendicularly to them, so that the bottom groove 25 forms a substantially right-angled frame. The frame arm 2 is designed as a hollow profile, wherein the bottom groove 25 has at least one fastening lug extending vertically through the opening into the interior of the hollow profile. The fixed connecting piece is bolted to the vertical profile surface 13 of the frame arm 2 . The base plate 4 is frictionally connected to the mounting rail 5 by means of the locking member 7 provided on the opposite mounting rail 5 .

Abstract

The invention relates to a switchgear cabinet (1) comprising a frame consisting of frame arms (2), the open bottom surface (3) of which can be closed by means of at least one bottom plate (4), wherein two opposite sides along the bottom surface (3) The frame arms (2) respectively extend a mounting rail (5) with a horizontal supporting surface (6), the base plate can be placed on the supporting surface, and the mounting rail (5) has a locking piece (7), which The locking member includes a locking claw (8) spaced vertically from the supporting surface (6), and is characterized in that the locking claw (8) can be maintained in an open position with the base plate (4) when the base plate (4) is released for removal. Back and forth movement between the supporting surface (6) and the closed position of the locking pawl (8). According to one embodiment, the mounting rail (5) is provided by a bottom groove.

Description

technical field [0001] The invention relates to a switchgear cabinet that can be mounted without tools, comprising a frame consisting of frame arms, the open bottom of which can be closed by means of at least one bottom, wherein two opposite frame arms of the bottom each extend with a An installation track with a supporting surface, on which the bottom plate can be placed, and wherein the installation track has a locking part, and the locking part includes locking claws arranged vertically at a distance from the supporting surface. For switchgears arranged in rows with each other, the mounting rails can also extend along opposite frame arms of adjacent switchgears. Such a switchgear is known from DE 44 46 223 C1. Similar switch cabinets are known from DE 101 47 342 A1, DE 197 30 430 A1 and DE 10 2007 014 786 A1. Background technique [0002] In the switchgear cabinet known from DE 197 30 430 A1, the base plate is connected to the bottom of the switchgear cabinet via an inn...
