  • Patent number: 6814417
    Abstract: A switchgear cabinet that has a frame stand with vertical frame profiles. According to this invention, a lateral casing is attached on at least one side of the frame stand to two vertical frame profiles that are assigned to the side. A mounting wall is arranged at a distance from the lateral casing while facing the interior of the switchgear cabinet. A cable installation space is formed between the mounting wall and the lateral casing, and the mounting wall is detachably fastened to the frame stand by retaining elements. This invention increases the number of possible ways of installing cables in a switchgear cabinet of this type. Thus, according to this invention the mounting wall is arranged between the vertical frame profiles of the side of the frame stand. An edge cable feedthrough is formed between at least one of the vertical sides of the mounting wall and the assigned vertical frame profile.

  • Patent number: 6748711
    Abstract: A door for a housing containing electrical components, in particular a switchgear cabinet, having a door frame, which has two vertical profiled frame sections spaced parallel apart from each other and connected at their longitudinal ends by horizontal transverse stays. Vertical and/or horizontal profiled cover elements are applied on an outside of the door to the vertical profiled frame sections and/or the transverse stays. The vertical profiled frame sections have receivers into which at least one cover panel can be inserted, which at least partially covers a door panel area surrounded by the door frame. To be able to equip the door panel area modularly, the receivers of the vertical profiled frame sections are formed as grooves in which edges of the sheathing panels are held. On their longitudinal sides the transverse stays have shoulders, each of which supports at least one plug-in shoulder. The plug-in shoulders are fixed in plug-in receivers of the vertical profiled frame sections.

  • Patent number: 6702125
    Abstract: A support frame for receiving external electrical devices, having a base frame on which two vertical supports are fastened, which are arranged parallel at a distance from each other and each of which has a first profiled leg. The first profiled legs face each other, project into the installation space formed by the supports and have at least one row of attachment receivers cut in a division pattern. In order to retrofit such a support frame for different fastening size systems, each one of the supports has at least one second profiled leg, which has a row of attachment receivers cut in the division pattern and which projects from the support facing away from the installation space. The division pattern of the first profiled leg is different from that of the second profiled leg. The supports are fastened on the base frame in two installation positions, which are rotated by 180° around the longitudinal axes of the supports.

  • Patent number: 6679088
    Abstract: A locking arrangement for a switchgear cabinet, having a holding device, which contains a manual lever in a handle receptacle. The manual lever can be arrested in a locked position on the holding device by a displaceably seated bolt. For actuating the bolt, the holding device, which is in operative contact with the bolt, contains a lock in a lock housing. To make a locking arrangement accessible with little cost to a limited and definite group of people in connection with switchgear cabinets, the holding device contains a secondary lock which is also in operative connection with the bolt, or the secondary lock is in operative connection with a second bolt by a second actuating member, wherein the second bolt arrests the manual lever in a blocking position on the holding device.

  • Patent number: 6401940
    Abstract: A frame for a switch cabinet, having vertical profiled frame parts, a floor frame and a cover frame. The floor frame and the cover frame are configured as punched, bent parts made of a steel-sheet blank and have a horizontal floor facing the switch cabinet interior on which floor the vertical profiled frame parts are fixed. The floor has a reinforced edge which is bent away from the switch cabinet interior. To be able to assemble this type of frame simply and rapidly, four plug-in protuberances are fixed to the floor of the floor frame and the cover frame, which each have at least one threaded recess. The vertical profiled frame parts have plug-in recesses by which they are inserted onto the plug-in protuberances. The vertical profiled frame parts also have screw holes which are arranged such that they align with the threaded recesses of the plug-in protuberance and fixing screws are threaded into the screw holes and screwed into the threaded recesses.

  • Patent number: 6315132
    Abstract: A rack for a switchgear cabinet with vertical and horizontal profiled frame sections, wherein two of the horizontal profiled frame sections are connected by a corner connector to at least one rack corner area. Two horizontal profiled frame sections are connected with each other, forming a corner angle and having a receptacle, which is open toward the exterior of the rack. The receptacle is symmetrical with respect to a bisecting line dividing an angle of the corner angle. A corner connector is fixed in place in the corner connector. The vertical profiled frame section can be fixed in place in the receptacle using a fastening shoulder of the corner connector. The vertical profiled frame section can selectively be designed symmetrical or asymmetrical with respect to the bisecting line of the angle of the receptacle. The corner connector has a compensating element for fixing the asymmetrical profiled frame section in place.

  • Patent number: 6190081
    Abstract: A fastening device for attachment of, for example, mounting rails to vertical frame profiles of a switchgear cabinet. The frame profiles have rows of evenly distributed fastening retainers. A fastening block, which has fastening retainers for connecting the mounting rail or the like, can be added to the frame profile. In order to secure fastening of the mounting rail on the vertical frame profile, which only requires a small outlay of parts, the fastening block is manufactured either as a punched and bent element from a sheet metal blank or as an extruded element. At least one hook element projects from the fastening block, which can be suspended in an associated fastening retainer of the frame profile. The fastening block has two lateral walls, which extend at right angles with respect to each other and form a common vertical inner edge facing the interior of the switchgear cabinet. The lateral walls are equipped with the fastening retainers for connecting the add-on elements.
