Abstract:
An arrangement for converting rotary motion into translational motion in which a motion-transmission device that is movable translationally, is divided into two strings that move longitudinally along their direction of motion. A driving motor provides rotational motion through a rotary drive. The strings are guided transversely and are positioned outside of a guide where they become separated. The strings, on the other hand, become united inside the guide, and this guide prevents the strings from being movable from each other laterally. The strings have teeth on sides facing each other in vicinity of the guide, and these strings have ends secured to an intermediate component in the guide, remote from the rotary drive. The intermediate component is common to both strings, and they become disengaged in vicinity of the intermediate component.
Abstract:
A vehicle power window actuator for pivoting a glass view panel about an axis by means of back-and-forth linear movement of a wire cable. The wire cable has a jack screw portion swaged to one end engaging a gear which is rotated by an electric motor to produce linear movement of the cable. The other end of the wire cable is swage-attached to a rigid curved rod terminating in a ball-shaped end portion. The curved rod is housed in an arcuate hollow support assembly which is attached to the vehicle body adjacent the movable edge portion of the window panel so as to direct the end portion of the curved rod against the panel. A connector assembly between the end portion of the curved rod and the window accommodates linear movement of the ball-shaped portion in a direction parallel with the plane of the glass as the window pivots outward. In addition, the end portion moves with and rotates with respect to the glass. The connection compensates for substantial misalignment which often occurs between the axis of the curved rod and the attachment of the connector assembly to the window.
Abstract:
A mechanism for opening and closing an angularly movable panel, comprising a drive box for attachment to a fixed frame, the drive box housing a cable wheel rotatable upon translation of a control cable when in operative association therewith, a chaincase having a sprocket operatively connected with a chain located in a casing, the chain being for attachment at one end to an angularly movable panel, rotation of the sprocket effecting translation of the chain into, or out of, the casing in accordance with the sense of sprocket rotation, the chaincase being mountable in any of four different positions on the drive box.
