A profile element for attachment to the rear side of a façade panel, which in turn is fastened to a base such as a building surface or substructure. The profile element is formed in one piece and includes three functional sections arranged one after another: a fixing section for fixing the profile element to a base; a support section for attachment to the façade panel; and a spacer element which, in the installed state, ensures the correct distance between the base and the rear side of the façade panel. The profile element is extendible by a supplementary element, which has functionally similar elements and is only used if required by the geometry of the façade panel. The supplementary element is usable for positive connection to the profile element of an adjacent façade panel. Such a façade system provides flexibility for a wide variety of types and dimensions of façade panels.

Facade fastening system having profile elements

A centering device for guiding a fastener or a drill during a setting operation. The centering device is arranged in or at a passage opening of a component, which forms a fastening point. The component can be a substantially flat metal part, in particular a lug or bracket for a façade element. The centering device is arranged at the plane of the back of the passage opening and includes a collar and connecting elements between the collar and the edge of the passage opening. The collar has a substantially flat to bead-like annular shape and is formed in the component. The central opening of the collar forms a centering seat for a fastener or drill during setting. A fastening arrangement has a component, centering device and matching screw. The screw forms a form fit via its lower head portion in the passage opening after completion of the setting process.

Centering device and fastening arrangement

A ball screw having a spindle nut (), a threaded spindle, and a retaining element () is provided. The retaining element () is connected in a form-fitting, play-free manner to the threaded nut () by a projection () which fits around the outside of the threaded nut () in an end region. The threaded nut () and the retaining element () functioning as a force transmission member are first positioned precisely during manufacture and then connected by a form-fitting, in particular play-free connection, in particular by caulking, crimping, clinching or other deformation processes.

Ball screw drive

A ball screw drive () including a threaded spindle () having a first, free end () and a second end () which can be connected to a drive, and a spindle nut () at least partially enclosing the threaded spindle () coaxially. A plurality of balls () recirculate in the space between the threaded spindle () and the spindle nut () form the core element. An extension sleeve (), which connects coaxially to the spindle nut (), is fixedly connected to the latter and moves together with it relative to the threaded spindle (). At the first end () of the threaded spindle (), a substantially circular bearing ring () is attached to the outer circumference of the threaded spindle (), which circular bearing ring serves as a shaft bearing between the threaded spindle () and the extension sleeve () and which has a noise-dampening effect due to at least one integrated spring/damping element. This spring/damping element of the bearing ring () is preferably a combination of at least one notch () on the inner circumference of the bearing ring () and an annular gap ().

The invention relates to a ball screw () with a threaded spindle (), a nut (), rolling bodies () and at least one deflecting device (), wherein the threaded spindle () is displaceable by rotation, and wherein the deflecting device comprises an inner first body part () and an outer second body part (), which body parts together form a deflecting channel (), wherein the deflecting channel () has two tubular ends () which are connected to each other via a transfer region (), wherein the tubular ends () of the deflecting channel are in each case formed by mutually complementary partial tubular sections () of the body parts (), and wherein a sleeve () surrounding the nut () is provided, the deflecting device () sits in an opening () in the nut (), the deflecting device () projects radially beyond the outer lateral surface of the nut () in a relaxed state when the sleeve () is absent and, in the presence of the sleeve (), said sleeve exerts a radially inwardly directed force on the deflecting device ().

Ball screw

A threaded spindle (), having a drive part (), which has a longitudinal axis (A) and is mounted in a first journal (), and having a threaded part (), which has a longitudinal axis (B), and having a threaded nut (), which is mounted in a second journal () and in which the threaded part () is guided. The drive part () and the threaded part () are formed as separate parts and are each provided with at least one coupling element (), which are connected to each other in an articulated manner by plugging together. An offset of the longitudinal axes (A, B) can be compensated in this manner. The two-part threaded spindle () forms a threaded drive with the threaded nut () thereof, which can for example be used in a parking brake of a vehicle braking system.
