  • Publication number: 20090083956
    Abstract: A tensioning device for at least one cable control switch is described. The tensioning device includes a holding element for clamping and securing a cable thereto. A housing is connected to the holding element. An adjustment device is disposed between the housing and the holding element to permit adjustment between the housing and the holding element, thereby permitting a predetermined tension to be applied to the cable. The device also includes an electronic device for detecting the tension in the cable and for generating a signal indicative of the tension.

  • Patent number: 7271358
    Abstract: A switching hinge comprises a hinge housing (6) at which a hinge flap (4) is swivellably disposed, a switching element (2) coupled with the hinge flap (4) being provided, which switching element (2) triggers a switching operation at a built-in switch (7) in a predetermined position of the hinge flap (4). According to the invention, the built-in switch (7) can be adjusted relative to the switching element (2) for adjusting the switching point. Particularly, a precision adjustment can be carried out so that an adaptation to the respective installation situation becomes possible.

  • Publication number: 20070068778
    Abstract: A switching hinge comprises a hinge housing (6) on which a hinge flap (4) is swivellably disposed about an axis (3). A switching element (2) coupled with the hinge flap (4) is provided on the axis (3), which switching element (2) triggers a switching operation at a built-in switch (7) in a predetermined position of the hinge flap (4). In this case, the switching point of the built-in switch (7) can be adjusted later. For this purpose, an exchangeable connection element (5) for transmitting rotating motions is preferably provided between the switching element (2) and the hinge flap (4), which connection element (5) can be mounted in different angular positions to the hinge flap (4) and/or the switching element (2).

  • Patent number: 6913247
    Abstract: A quick-action tensioning device (1) for cable control switches comprises a holding element (2), to which a cable (3) can be fastened in a clamping manner, and a housing (8), which is connected with the holding element (2). According to the invention, devices (9, 10) for a precise adjusting are provided between the housing (8) and the holding element (2). In particular, a nut (10) can be used for the precise adjusting, so that the cable tension can be continuously adjusted, in which case a rough adjustment as well as a precision adjustment can be carried out.

  • Patent number: 6667449
    Abstract: A switch hinge is described having a first hinge wing, which accommodates a switch operable by a lever, having a second hinge wing and having a shaft which, in the operative position, is non-rotatably connected with the second hinge wing. The shaft, on its circumference, has a switch groove which extends in the direction of the shaft axis and into which an operating pin connected with the lever dips in a predetermined swivelling position between the two hinge wings. In a preassembled condition, in which the operating pin rests in the switch groove, the shaft is secured by a lock against rotation with respect to the first hinge wing, and the second hinge wing is freely swivellably with respect to the shaft. A screw screwed into the face-side end of the first hinge wing axially displaces the shaft by a predetermined extent out of the preassembled position into the operative position.

  • Patent number: 5929404
    Abstract: A safety switch includes a switch housing which accommodates a switch as well as mechanical and electrical and electronic components, and a head portion securable to an end face of the switch housing in several predetermined angular positions and accommodating a mechanical switching element e.g. a switching wheel which is operated by an actuator. A rigid positioning element is detachably secured to the switch housing and formed with a safety member, whereby the positioning element is adjustable between a locked position in which the safety member is positively engaged in the head portion and an idle position in which the safety member is disengaged from the head portion for allowing a rotation and re-positioning of the head portion relative to the switch housing.

  • Patent number: 5909166
    Abstract: A safety switch includes a spring-biased locking pin which is displaceable axially inside a switch housing by a lifting magnet against the biasing force of the spring to switch a switching element between a blocking position and a release position, and a retention magnet which holds the locking pin in the release position when the lifting magnet is de-energized.
