For easily assembling an electric motor a locking lug is formed onto the brush support plate. In an assembly position the ratchet lug of said locking lug engages a cavity of the brush and keeps it at a distance from the commutator so that the commutator can easily be installed between the brushes. In order to release the arrest of the brushes during the assembly a releasing part of the locking lug projects into a recess in the housing cover. This arrangement is easy to manufacture and reduced the number of assembly steps.In a second embodiment the releasing part of the locking lug lies above the front side of the housing cover and projects into a recess in the housing cover lid.

A connector device for connecting an exterior deck structure to a contiguous building the connector having a pair of interlocked non-contacting cable loops, with a plastic plug encapsulating the interlocked ends of the cables and separating the cables to act as a thermal barrier. An expanded head at one end of the plug, with associated foam washer seals against a deck header. The exterior cable end of the connector is attached to a deck joist and the interior end of the connector is attached to a building joist, wherein the respective joists may be laterally offset. The connector prevents detachment of the deck from the building during severe tectonic of weather activities.

A device for connecting an exterior deck structure to a contiguous building via a bore-hole through the deck ledger and building header retains the deck in place in the event of earthquake or similar stresses. A pair of tension members comprising interconnected tensile links, are encapsulated in a generally cylindrical plastic plug to maintain 1/2 to 2 inches separation, to provide a thermal barrier. A pivoting toggle pin on the end of one link pivots between a first position aligned with the axis of the link and a second position transverse to the axis. The plastic plug may have an extending lip supporting the pivot pin in axially alignment. The second link may be rigid or flexible, has a sealing member adapted to slide thereon to seal the bore-hole. The second link is adapted to be fastened securely to a joist or other appropriate member of the deck.

The invention relates to a wiper drive comprising a housing, a reversing motor and a gear mechanism connected downstream of the reversing motor, wherein a swaying element for driving at least one wiper arm or a wiper arm rod is provided on the gear mechanism output shaft, and wherein the operating range of the swaying element lies within a pivoting range which is delimited by two mechanical stops, wherein at least one stop is designed such that it can be removed and/or moved in such a way that the swaying element, when the wiper drive is mounted on a support frame, can be moved from a first mounting position, which lies outside the pivoting range, into the pivoting range without being obstructed by the stop. The invention furthermore relates to methods for mounting a wiper drive on a support frame.

The invention relates to an electromotive drive comprising an electric motor with a commutator that is located in a motor housing, in addition to gearing that is flange-mounted on the electric motor. In the drive, the armature shaft passes through an opening into the interior chamber of a gearing housing. A screening element is fixed onto the shaft to rotate with the latter. The screening element almost completely seals the opening against abraded carbon particles or dust from the brushes. The screening element also carries a control magnet that co-operates with a sensor of the motor control module.

The invention relates to a brush holding plate comprising tubes and brushes which are guided into said tubes. The brushes are guided in a spring-loaded manner in the radial direction towards a central opening in the brush holding plate. The invention is characterized in that the tubes are arranged on the brush holding plate in such a way that they can be displaced from a radially outer pre-assembly position into a radially inner end assembly position.

The invention relates to a windscreen wiper drive mechanism in which an output lever can be fixed on a gear wheel at a predetermined angle, the gear wheel adopting a position at a defined angle. Before assembly, the output shaft should be connected to the output lever in such a way that it cannot be detached. The invention also relates to a method for assembling a drive system of this type. The inventive method consists essentially of the following steps: moving the gear wheel into the defined end position (park position) independently of engagement with the output shaft and then connecting the output shaft to which the output lever was previously undetachably fixed to the gear wheel, with a press fit. Advantageous embodiments describe appropriate bearing possibilities for the gear wheel and suitable steps for facilitating the pressing-in process.
