Abstract: A sprung stem for bicycles, in particular for racing bicycles and gravel bikes, for the sprung connection between the handlebar and the head tube and/or the steerer tube with improved damping is proposed, wherein a coupling apparatus for mechanical coupling of the connecting parts is provided, which coupling apparatus comprises at least one elastomer body which is mounted in such a way that it is deformed during pivoting of the static fastening device with respect to the handlebar holder, in order thus to absorb force and to damp the relative movement between the handlebar and the head tube.

Abstract: A device for use on a numerically controlled machine tool for application in a method for measuring the numerically controlled machine tool, including: a first measuring element for measuring via a measuring apparatus, a second measuring element for measuring via the measuring apparatus, a spacer element on which the first measuring element and the second measuring element are arranged spaced from each other, and at least one fastening portion for fastening the device to a machine part of the machine tool.

Abstract: A device for shortening the spring path of a suspension fork for bicycles includes a cable; a fixing device for fixing the cable to the suspension fork tubes, which can be moved relative to the bicycle frame; and a cable clamping device, which can be secured in the region of the handlebar, preferably on the front-end section, for detachably fixing the cable, wherein the spring path is shortened in an infinitely variable manner. Thus, an infinitely variable lowering device is produced which is independent of a suspension fork.

Abstract: A safety helmet, in particular for cyclists, includes a self-contained portable semi-shell helmet (H), on which an integral part (1) enclosing the chin and the occiput/neck area can be fixed in a detachable way. The semi-shell helmet (H) is equipped as a self-contained helmet with a chin strap fastening and all that belongs to known helmets, This hence enables, depending on the intended use, only to wear the upper helmet part or the assembled integral helmet.

Abstract: A clamping device for fixing a tubular object (S), in particular for a seat post (S), comprises at least a clamping area (6, 7) which, under pressure, is elastically deformable and media feed lines (8, 9) to the clamping areas (6, 7). Set under pressure, the tubular object is fixed in a force-fit manner and without clearance. Used on a bicycle, e.g. the seat post (S) can be height-adjusted by means of a remote control (F) during a ride.

Abstract: A method for measuring a program-controlled machine tool using a measuring sphere. According to this method the measuring sphere having known dimensions is positioned on a machine part. A sensing element installed in the machine is moved to a selected initial position in which it is located approximately 10 mm above the vertex section of the sphere. Then the sensing element is repeatedly moved until it contacts various points on the surface of the sphere, and the coordinate values of those points of contact are input into the controller. Thereafter the spatial position of the center of the sphere is calculated and compared with target values stored in the controller.
