Abstract: A device for fixing especially surface-like workpieces has a flexible attachment surface at least one holding device which holding devices may be embodied as spheres which are held in openings by an elastic surface-like component in a resilient manner. Between the elastic surface-like component and the attachment surface, there exists a reduced pressure, so that, as a consequence of the reduced pressure, or the air pressure of the ambience, respectively, a workpiece resting at the attachment surface is pressed against the attachment surface 2. Consequently, spheres are pressed out of the openings only where the workpiece rests on the attachment surface in order to be held.

Abstract: A window element has a cover pane which is substantially flush with an outer skin of an aircraft or other transport, achieving a fluid-dynamically favorable, substantially unbulged exterior surface. As a result of the presence of an additional back-ventilated cover pane arranged in front of the actual outer pane of the window element, a fluid-dynamically favorable integration of the window element into the outer skin of an aircraft fuselage airframe is achieved. Any deformation, such as any buckling or bulging of the outer pane of the window element, as a result of a difference in pressure between the interior of the aircraft fuselage airframe and the exterior space at cruising altitudes, has no fluid-dynamically disadvantageous effect. The outer pane is covered by the cover pane which remains substantially undeformed with respect to the outer skin of the aircraft fuselage airframe, for example. Any deformation of the cover pane is largely eliminated by back-ventilation.

Abstract: In present application, a device for fixing especially surface-like workpieces 1,9 is described having an attachment surface 2. The attachment surface 2 embodied to be flexible, and has at least one holding device. As a consequence of the flexible embodying of the attachment surface 2, it may be possible to adjust the device to varying workpieces 1,9 having different surface geometries. In order to obtain an air-tight sealing, the one or the several holding devices may be embodied as spheres 5 which by means of an elastic surface-like part 8 in a resilient manner are held in openings 6 especially embodied in the form of bores. Between the elastic surface-like part 8 and the attachment surface 2, there exists a reduced pressure, so that, as a consequence of the reduced pressure, or the air pressure of the ambience, respectively, a workpiece 1,9 resting at the attachment surface 2, is pressed against the attachment surface 2.

Abstract: A window element has a cover pane which is substantially flush with an outer skin of an aircraft or other transport, achieving a fluid-dynamically favourable, substantially unbulged exterior surface. As a result of the presence of an additional back-ventilated cover pane 10 arranged in front of the actual outer pane of the window element, a fluid-dynamically favourable integration of the window element into the outer skin of an aircraft fuselage airframe is achieved. Any deformation, such as any buckling or bulging of the outer pane of the window element, as a result of a difference in pressure between the interior of the aircraft fuselage airframe and the exterior space at cruising altitudes, has no fluid-dynamically disadvantageous effect. The outer pane is covered by the cover pane which remains substantially undeformed with respect to the outer skin of the aircraft fuselage airframe, for example. Any deformation of the cover pane is largely eliminated by this back-ventilation.
