Abstract
The screw unit for the adjustable and lockable spanning of distances between structural components, brackets, and for adjusting assemblies, etc., consists of a threaded pin, which has adjusting surfaces and a central bore passing through it, and a nut, which is screwed onto the threaded pin. This nut is designed as a support sleeve with an internal thread and adjusting surfaces, into which the threaded pin can be screwed until it is more or less flush. On the end facing an adjusting collar, the support sleeve is provided with an inward-projecting, ring-shaped collar with the internal thread, whereas the free end of the threaded pin is provided with a stop element to prevent the pin from being completely unscrewed. So that the unit can be adjusted not only in the height direction but also in the direction perpendicular to that, the support sleeve is attached to a sliding support element so that it can be shifted in the direction perpendicular to the longitudinal axis of the screw unit, the support element itself being held in place on a spacer.
