  • Patent number: 6637842
    Abstract: A switchgear cabinet with at least one cabinet door, which can be locked by a lock element of the switchgear cabinet body wherein, in a locked position of the cabinet door, a locking engagement between the lock element and a counter-lock element can be released by a triggering device, which is in an operative connection with the lock element or the counter-lock element via an actuating unit. So that the cabinet door can be opened in a simple way from the inside of the switchgear cabinet, the actuating unit of this invention is designed as a Bowden cable, with one end connected to the triggering device via a connecting element and an other end connected with the lock element or the counter-lock element. The triggering device has a rotary body which is pivotably seated about an axis of rotation. The end of the Bowden cable is fastened eccentrically offset with respect to the axis of rotation on the rotary body, and a lever with a handle is connected to the rotary body.

  • Patent number: 6590164
    Abstract: A device for fastening a support rail on frame legs of a rack of a switchgear cabinet, wherein the frame legs have two fastening sides oriented perpendicularly with respect to each other and each has a row of square fastening perforations. Both ends of the support rail have fastening brackets which have at least one suspension hook and are matched to a cross section of the fastening perforations in the first fastening side of the frame legs spaced apart between the fastening brackets and to the spacing of the fastening perforations of the frame legs. A clamping plate is assigned to each fastening bracket of the support rail and has retaining claws and extends with the retaining claws behind the fastening perforations in the second fastening sides of the frame legs. The clamping plates have a threaded receiver for a clamping screw for maintaining them on the support rail in an elongated hole extending in the linear direction of the support rail and can be clamped together with them.

  • Patent number: 6489567
    Abstract: A device for connecting bus bars of a bus bar system with connectors of a piece of electric installation equipment using connecting pieces, which are cut, angled and/or bent from a rectangular flat material. The cost for different bar elements for the connection can be reduced without a need to surrender adaptation to the transmission of current strenghts of different sizes because the connecting pieces are respectively formed by several identical bar elements which are held, vertically with respect to their width, at a distance from each other which corresponds to a thickness of the flat material. The bar elements are maintained apart by a packaging holder which has alternating spacers and holding plates perpendicular with respect to a broad side of the bar elements. The holding plates delimit receivers for the bar elements on both sides of the packaging holders.
