  • Patent number: 9948072
    Abstract: A mounting system (1) includes in switchgear cabinets a horizontal mounting strip (3) with a front face to which an electrical device (2) can be secured. The mounting strip (3) has a locking flange (63) on its rear side lying opposite the device (2) that is to be secured. The locking flange, onto which another component (65) of the mounting system (1) can be directly locked or can be indirectly secured by a lockable adapter element (66), extends in the longitudinal direction of the mounting strip (3).

  • Patent number: 9711952
    Abstract: A mounting system (1) for arranging electric devices (2), for example switchgear cabinets, includes at least one preferably horizontal mounting strip (3) to which at least one device (2) can be secured. The mounting strip (3) includes a support rail (6) to which the device (2) can be releasably fastened and located in a first section (41) of the mounting strip. The first section is central in relation to a cross-sectional view through the mounting strip (3), transversely to its longitudinal axis. A third section (43) of the mounting strip located at a distance from the support rail (6) is at a greater vertical distance (44) from the bottom point (39) of the support rail (6) than a second section (42) at its end that is closer to the support rail (6), especially its end adjoining the support rail (6). The second section is located between the first section (41) and the third section (43).

  • Patent number: 9515458
    Abstract: A mounting system (1) arranges electric devices (2), in switchgear cabinets. The mounting system (1) includes horizontal mounting strip (3) to which a device (2) can be secured. At one of its longitudinal edges, the mounting strip (3) includes a receiving device (20) extending along the longitudinal axis of the mounting strip and receiving components (7, 8, 9, 10, 11). The receiving device (20) has locks (22, 23) to be interlocked with an associated lock (26) of the component (7, 8, 9, 10, 11) inserted into the receiving device (20). Depending on the design of the associated lock (26) of the component (7, 8, 9, 10, 11), the interlocking action can be cancelled exclusively by a pulling force acting on the additional component (7, 8, 9, 10, 11) or cannot be so cancelled but is self-locking.

  • Patent number: 8511627
    Abstract: An apparatus (10) for arranging and fastening electrical units (152, 154, 156), in particular in a switch gear cabinet (1), has a mount element (14). On the fitting side of the mounting element, a module mount (150) with at least one electrical unit (152, 154, 156) can be fastened. The mount element (14) has a groove (16) extending in a longitudinal direction and open towards the fitting side. The module mount (150) can be suspended in the groove in an optional position in the longitudinal direction of the groove (16). The groove (16) is shaped such that, owing to the force of the weight acting on the suspended module mount (150), the module mount (150) is arranged on the mount element (14).
