  • Patent number: 9096415
    Abstract: A lifting device for scissor lifts, in particular for raising motor vehicles, which during the starting phase of the lifting movement requires a reduced force for raising. The lifting device for scissor lifts includes at least two scissor arms which cross one another, a linear actuator for raising a scissor arm, a double lever joint which is pivotably mounted on a scissor arm; wherein the double lever joint couples the lifting movement of the linear actuator to at least one scissor arm.

  • Patent number: 8770549
    Abstract: Example methods, apparatus, system, and articles of manufacture for releasably locking components that are moveable relative to one another are disclosed herein. A disclosed example locking apparatus includes a locking device mountable to a first component and including at least one locking member. The example system also includes a catch member mountable to a second component. The catch member has a plurality of substantially similarly formed catches. The locking member is engageable with at least one catch in a plurality of predetermined catching positions in at least one of a releasable, form-locking manner or a releasable, force-locking manner. The example system also includes a force member to produce a relative movement between the locking member and the at least one catch. In at least a partial region of the catch member, at least a first catching position, a second catching position and a third catching position are traversable by the locking member.

  • Publication number: 20100243973
    Abstract: The invention relates to a scissors-type lifting platform, in particular for vehicles: including: stationary support rails on or in the floor level, at least two scissors arms which cross each other and are retained and guided with their bottom ends in the support rails, a hinge connecting the two scissors arms approximately centrally to each other, a lifting assembly engaging the scissors arms for spreading and contracting the scissors arms, at least one travel rail having contact areas and supported on the top ends of the scissors arms, wherein one of the scissors arms is connected to a travel rail with its top end in hinged manner and the other scissors arm is guided on the travel rail with its top end in longitudinally displaceable manner upon the lifting and lowering movement of the scissors-type lifting platform, characterized in that the longitudinally displaceable ends of the two scissors arms (12, 13; 20, 21) can be arrested with the associated travel rail (28) at least in the lifted position.
