Abstract: A fan (10) is disclosed having a base (11) and a protective housing (12) encasing an electric motor (13) and a blade assembly (14). The base has two pivot mounts (21) to which a front support leg (22) and a rear support leg (23) are mounted. Each leg includes a mounting flange (24). The pivot mounts allow the pivotal movement of the protective housing relative to the pivot mounts and about horizontal axis AA. The base also includes a ceiling mount portion (28) which is mounted to the ceiling C. The ceiling mount portion includes a mounting plate (32), a rod (33), and a cup-shaped coupler (34). The coupler has an annular groove (35) therein adapted to receive the mounting flanges. The coupler is configured to allow the flanges to be rotated while nested within the groove, thereby allowing pivotal movement of the fan about the rod and about vertical axis AB.

Abstract: An electrical power outlet or switching device suitable for installation as fixtures in household and commercial buildings is provided with improved mechanisms for making contact with the building wiring. Contact members having slots between contact edges are provided to enable an end of an insulated wire or cable to be inserted therein. Upon insertion the contact edges cut through portions of the insulation to make electrical connection to the conductor therein and to mechanically secure the wire/cable end also. In one arrangement, a slidable block is provided adjacent the slot and having an aperture therethrough which can be aligned with a widened portion of the slot. A wire/cable end can be inserted in the aperture and widened slot portion and the block slid along the slot to force the wire/cable end into the slot and engagement with the contact edges. The connection system enables fast and efficient connection of wiring to the power outlet or switching device.

Abstract: An earthing module for the termination of earthing conductors to contact elements and for latching on rails, where quick, convenient and reliable connection and disconnection of one or several earthing lines is possible for a large range of wired diameters. An earthing plate is connected on either side optionally to a known insulation displacement contact with inclined insertion portion via a central tapping portion or to a screw contact terminal or on its one side to an insulation displacement contact with inclined insertion portion via the central tapping portion 15 thereof and on its other side to a screw contact terminal.

Abstract: A terminal block with a plastic housing and insulation displacement contact elements provided therein for incoming and outgoing conductors. In order to simplify the termination of the conductors at the insulation displacement contact elements and to permit a protection of the conductors against surge voltages and surge currents, it is provided that the insulation displacement contact elements are disposed separately from each other in the plastic housing, and that each insulation displacement contact element is provided with a center tapping. The spaced center tappings opposedly disposed in the plastic housing can be connected with each other by different function plugs.
