  • Patent number: 6575657
    Abstract: A device for fastening of attachment elements, such as mounting rails, mounting plates, deposit plates and the like on a frame leg of a switchgear cabinet rack, wherein the frame legs are designed symmetrically in relation to their cross-sectional diagonal line and are aligned with the latter with the diagonal line of the rack. On the inside of the frame legs oriented toward the interior of the rack, the frame legs form a fastening receiver with two fastening profile sides which are disposed vertically in respect to each other and extend parallel to the facing outsides of the switchgear cabinet rack. The frame legs form system fastening receivers in the form of square or rectangular openings and fastening bores and make transitions into additional profile sides having corresponding rows of fastening receivers, which extend perpendicular to the facing exteriors of the switchgear cabinet rack.

  • Patent number: 6533605
    Abstract: A bottom plate fixing device for a switchgear cabinet, whereby an edge of at least one bottom plate is placed on a support flange of a bottom frame of the switchboard cabinet and is preloaded by at least one fastening clip. The clip has two parallel legs which are held on a connecting section, whereby the first leg engages behind the support flange of the bottom plate and the other leg holds a screw in a thread. The screw can be tightened against the edge of the bottom plate. The bottom plate and the bottom frame can be reliably placed on the same electrical level by supporting the first leg on the support flange by cutting and/or sharpening contact elements, and such that the screw is in electrically conductive contact with the edge of the bottom plate.

  • Patent number: 6497437
    Abstract: A slide rod locking system, especially for locking the door of a switchgear cabinet, having a handle which is coupled to a control element by a control mechanism. The handle can move around a pivotal axis running perpendicular to the plane of the cabinet door. The control element can move in a parallel position relative to the plane of the cabinet door as a result of the movement of the handle. The slide rod locking system transmits powerful locking forces and at the same time can have a low-height design structure by arranging a lever on an articulated joint of the handle at a distance from the pivotal axis. The lever enables the force introduced into the handle to be transmitted to the control element and can modify its angle position with respect to the handle when moved.

  • Patent number: 6494779
    Abstract: A control cabinet with a frame having framing profiles and covered with side members and at least one door. The frame surrounds the inside of the control cabinet where electrical components are integrated. An air conditioning device which is placed on at least one vertical side of the frame rejects heat generated inside the control cabinet. This invention provides this type of cooling apparatus with additional equipment without the need for a large number of pieces. For this purpose, a separating member, parallel to the lateral side and placed at a distance therefrom, is attached to the framing profiles and forms with the side channel an air guiding channel. Moreover, the separating member comprises several passages for providing a physical connection between the air guiding channel and the inside of the control cabinet. Furthermore, air can be conveyed through the air guiding channel and through at least one passage by using at least one fan.

  • Patent number: 6488214
    Abstract: A control cabinet having a cabinet body with opened sides which can be closed at least partially by one or more side walls. An air conditioning device which is placed near at least one side wall rejects heat generated inside the cabinet body or guides it towards the inside of the cabinet body. This invention simplifies the design of the air conditioning device. For this purpose, an intermediate wall which is parallel to the side wall and located at a distance therefrom, is placed in such a way that it is oriented towards the inside of the cabinet body. In addition, the air conditioning device is placed in the intermediate space surrounded by the side wall and the intermediate wall.

  • Patent number: 6485067
    Abstract: A sliding rod closure for a cabinet door hinged on a switch cabinet body having a locking mechanism which has an actuating member displaceable in the direction of rotation. The actuating member is coupled to a sliding unit that has a spaced adjusting member situated perpendicular to the sliding direction of the rotational axis of the actuating member. The adjusting member can be operated by the actuating member. The sliding rod closure can be used to meet various requirements thus resulting in an easier operation. The adjusting member can be assigned to the actuating member in a variety of assembly positions, whereby the sliding direction of the sliding unit is maintained in various assembly positions. However, the direction of rotation of the actuating member is modified or the sliding direction of the sliding unit is also modified, and the direction of rotation of the actuating member is maintained.

  • Patent number: 6435759
    Abstract: A device for connecting switchgear cabinets which can be attached to each other. The switchgear cabinets have racks with frame sections and form connecting frames extending as far as connecting planes. The frame sections have side sections which are oriented towards an inner space of the switchgear cabinet. Corresponding frame sections of the attached racks are interconnected by one or several connecting elements with a positive fit. The connecting elements are fixed at receptacles of the side sections. In order to provide considerable flexibility in attaching different types of switchgear cabinets, the vertical frame pieces connected to the connecting element have different cross-sectional dimensions, the connecting element is fixed to a fixing receptacle of the first frame section by a first fixing element, and the connecting element grips the second frame section with a clamping element.

  • Patent number: 6435364
    Abstract: A wall-mounted installation housing for receiving electrical components, having a base part with a floor that can be screwed into the wall. A hood-like cover can be placed onto or over the base part and surrounds an installation space by two side walls, the floor and a cover. To be able to make good use of the available installation space it is possible to fix one or more supports to the base part which protrude from the floor of the base part in the direction of the hood-like cover and support it in relation to the base part. This invention provides supports having an assembly section fitted with fixing recesses to which fittings can be attached such that they face into the installation space.

  • Patent number: 6425610
    Abstract: A control cabinet with a cabinet body, whose open front side can be successively closed by an inner door and a closing door presenting a closing device. The inner door can be fixed against the cabinet body at the top and at the bottom by means of a two-armed locking lever and the closing door can be fixed against the cabinet body by means of a locking bar. The closing door partly overlaps the inner door in the closing area. With mirror-symmetrical locking levers, no elements of the locking levers protrude over the free edge of the inner door in any position of the locking levers and the locking levers are easily operated.

  • 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.
