  • Linear drive with safety mechanism for moving a structure
    Patent number: 7849756
    Abstract: A linear drive for adjusting at least one movable structure includes at least one spindle drive having a rotatable spindle. Disposed on the spindle and restrained against rotation is a lifting nut which is linked to the movable structure. At least one safety mechanism is disposed on the spindle without connection to the lifting nut and restrained against rotation. The safety mechanism includes an inner nut attached to the spindle and an outer guide bushing attached onto the inner nut, wherein the inner nut and the guide bushing have an engagement structure which effects a form-fitting engagement between the inner nut and the guide bushing during normal operation and is so constructed as to effect a disengagement between the inner nut and the guide bushing, when the safety mechanism is subjected to a predefined load torque.
