  • Patent number: 6877827
    Abstract: Switch cabinet with a rack that can be closed or is closed by at least one double-walled cabinet door, two side walls, a back wall and a top wall, where the side walls and the back wall in each case consist of an internal wall and an external wall and are attached to the rack and where a cover hood is placed on the top wall, the cover hood being hinged in the vicinity of the back wall, and can be made fast in the vicinity of the cabinet door in the closed position. By a special angling-off of the internal walls and external walls of the side walls and the back wall which are constructed as double walls, a simple and reliable attachment of the external walls is made possible.

  • Patent number: 6776464
    Abstract: A switchgear cabinet including rectangular frameworks of frame members, wherein, in the region of the outer corner edges, free spaces are formed for the accommodation of angled edges of the double-wall covering members, which are juxtaposed each other. At least one covering member is configured as a cabinet door, which has hinges on the framework, which is pivotally mounted with hinges and which is closable and openable by closure members on the framework. If the covering members and the cabinet doors have an interior wall and an exterior wall, the formed cavity extending at least partially over the free space of the associated vertical frame member, in the case of the cabinet doors, in the region of the covered free space, the cavity receives hinged members on the one vertical side and closure members on the opposite side.

  • Patent number: 6776465
    Abstract: A switchgear cabinet with a cuboid rack assembled from frame legs, wherein free spaces are formed in areas of the edges of the outer corners, for receiving folded edges of the panel elements meeting at the area. If at least the insides of the folded edges of the vertical panel elements are positioned at an angle of 45° with respect to the inside of the panel elements, then the outsides of the folded edges have a predetermined distance from the median line of the panel elements which meet each other in the area of the edge of the outside corner. Near the outer surfaces of the rack the inside surfaces of the panel elements rest directly on or by way of sealing elements on its frame legs. There is an increased security against vandalism in the area of all edges of the outer corners if the transition to the median line is symmetrically designed and if the panel elements and the cabinet doors are arbitrarily combined.

  • Patent number: 6769749
    Abstract: A switchgear cabinet with a cuboid rack assembled from frame legs, wherein free spaces are formed in areas of outer corner edges for receiving folded edges of meeting panel elements. If at least the folded edges of the vertical panel elements have at least two folded sections, which adjoin the panel elements whose insides are located directly, or via sealing elements, on the outer levels of the rack, and protrude into the free space of the facing frame leg, and the folded end sections extend parallel with respect to the median line of the outer levels meeting each other and their outsides are at the preset distance from the median line, then a transition which is symmetrical to the median line and has a narrow gap in the area of the outer corner edges and increased vandalism proofing is accomplished.

  • Publication number: 20040007951
    Abstract: Switch cabinet with a rack that can be closed or is closed by means of at least one double-walled cabinet door, two side walls, a back wall and a top wall, where the side walls and the back wall in each case consist of an internal wall and an external wall and are attached to the rack and where a cover hood is placed on the top wall, said cover hood being hinged in the vicinity of the back wall, and can be made fast in the vicinity of the cabinet door in the closed position. By means of a special angling-off of the internal walls and external walls of the side walls and the back wall which are constructed as double walls, a simple and reliable attachment of the external walls is made possible.

  • Publication number: 20040007950
    Abstract: The invention relates to a switch cabinet with a rack that can be closed or is closed by at least one double-walled cabinet door, three side walls, a top wall and a bottom wall, where the side walls each consist of an internal wall and an external wall and are attached to the rack. By means of a special angling-off of the internal wall for the side walls and the back wall, a completely sealed and shielded internal space of the switch cabinet is produced, wherein the rigid attachment of the internal walls and the external walls is performed from outside the supported interior of the switch cabinet.

  • Patent number: 6640980
    Abstract: A switchgear cabinet including rectangular framework of frame members, wherein, in the region of the outside edge corners, free spaces are formed to accommodate angled edges of the double-wall covering members, which abut each other. If at least the angled edges of the exterior walls of the vertical covering member have two angled portions, the interior walls of the covering members with their inner surfaces in the outer planes, directly or via sealing members, fit onto abutment profile sides of the frame members of the framework and are connected in front of the angled end portions of the exterior walls.

  • Patent number: 6615998
    Abstract: Fittings for mounting on frame members of a switchgear cabinet framework, the frame members having a free space towards the outside corner edge of the framework, which free space forms a receiver, which is closed towards the interior of the framework, is open towards the outside corner edge and is mirror-inverted relative to the diagonal of the frame member. The fittings have a mounting plate the cross-section of which is adapted to the cross-section of the receiver and which plate is connectable to the end profile side of the frame member. The mounting plate preferably has a central mounting bore. The mounting plate, in the longitudinal direction of the frame member, has a pre-determined width, which is preferably symmetrical to the mounting bore.

  • Publication number: 20020170810
    Abstract: A switchgear cabinet with a rack, placed with an underside on a base and connected therewith, and having a lower side closed by a bottom plate. The cost outlay for parts and assembly can be considerably reduced and made easier if on all four sides of the bottom plate the base is formed by a plurality of folds oriented toward the underside, wherein folded sections extend parallel with respect to the bottom plate and define a support surface. Further folded sections are supported on the underside of the bottom plate and/or are connected therewith, and the open underside of the rack is connected with the unit including the bottom plate and the base through the base and/or the bottom plate.
