The invention relates to a switching box with a framework support formed from framework side units. The switching box is sealed by having a bottom wall, top wall, two side walls, and the open sides of which can be closed by means of a cabinet door and a rear wall, or by means of two cabinet doors. The framework side units form a hollow profile, which have identical series of holes on the two sides that stand perpendicular to one another and are oriented toward the internal space of the box. The framework side units have a protruding sealing bar on the side which toward the external side of the box. The costs of parts and labor necessary for assembly are reduced while retaining universal construction. At least one portion of the framework side units are formed by multiple bending in a single piece with the bottom wall, the top wall and/or the side walls plates. The edging has a first section which extends perpendicular to the internal side of the plate and at its edge makes a transition into a second section which is bent outwardly and parallel to the plate. The end of the second section makes a transition into a third section which lies on the second section and is extended parallel to the plate beyond the second section. The third section is provided with a series of holes. At the end of the third section, a fourth section is bent perpendicular and toward the internal side of the plate and also have a series of holes.

Switching box

This invention relates to a base structure for a switch cabinet having in combination four corner sections, at least two transverse panels and at least two longitudinal panels. The corner sections have two vertical outer walls joined at right angles and the ends of the outer walls are bent inwardly to form mounting flanges provided with mounting holes. The top and bottom of the corner sections have cabinet mounting flanges with mounting holes. Transverse panels and longitudinal panels are screw-fastened to the corner section mounting flanges so their outer surfaces are flush with the outer surfaces of the corner sections. Corner sections, transverse panels and longitudinal panels are adapted to be assembled and disassembled from the interior of the base structure. This base structure configuration ensures that any panel may be removed from bases upon which switch cabinets are mounted in rows of cabinets, and reinstalled without moving the switch cabinets.

Switch cabinet base

This invention relates to a framework for a switchboard cabinet, comprising at least twelve interlocking frame sections of an identical hollow rectangular structure, in which the hollow rectangular structure has rows of holes and forms an outer corner at the junction of two perpendicular side sections. Opposite the outer corner, the hollow rectangular structure has two side sections, each extending parallel to an opposite side forming the outer corner. The outer corners of all frame sections are aligned correspondingly and face the interior of the framework. Due to the special construction and arrangement of the frame sections, a framework is produced which is expandable with positive sealing on all sides, and in which interconnecting transverse struts, support rails, structural elements and the like, may be installed on all frame sections.

Framework for a switchboard cabinet

A lock assembly for cabinet doors comprising a mounting plate attachable to the door panel and provided with a depression in its front face to receive a handle. The handle is connected to an operating shaft for a lock adjusting member in a spring loaded manner to cause the handle to be ejected from the depression pivoting about an axis perpendicular to the axis of rotation of the adjusting member. The hand lever is retained in and released from the depression by means of the lock assembly. The lock is installed in the mounting plate separate from the depression with the handle therein, and penetrates the door panel through an opening. The lock controls a slide adjustably disposed in the mounting plate by means of a detent element engaged in the depression, the detent element retaining the handle in the depression when the lock is in the locking position and releasing the handle which is ejected from the depression when the lock is in the unlocked position. This invention provides a lock assembly which has a small structural height, can easily be sealed, and has a conveniently and comfortably grippable handle.
