Definitions

• the invention relates to a vacuum holding device for fixing objects to mounting surfaces.
• Saugfußbefest Vacuum holding devices are known, for example, as Saugfußbefest Trenten.
• the suction feet of such Saugfußbefest Trenten consist of an elastic material, such as rubber or plastic.
• the technical effect of such Saugffure is that between the hollow interior and the mounting surface to which the squeegee is to attach when preparing a
• Chamber training The air is forced out of the chamber by pressing the squeegee against the mounting surface; it escapes between the sealing edge of the squeegee and the mounting surface. With decreasing contact pressure, the spring-elasticity of the suction foot in the chamber induces underpressure, which sucks the suction foot against the fastening surface.
• the known vacuum-holding devices aim at a good adhesion to smooth mounting surfaces. Adhesion to less smooth, rough surfaces is a problem. Such less smooth surfaces are, for example, the more or less horizontal top covers of dashboards in motor vehicles, the so-called dashboard.
• Negative pressure of the angle between the sealing edge and bearing surface is greater, resulting in an unrestrained and radially inward restoring force results and the Haftsaugvorides drops.

• the advantage of the invention is that the serving for setting pressure is applied not only from the center piece, but also targeted on the Saugfußwand and thus a better pushing away the air from the vacuum chamber is possible. This is especially important with increasing elasticity / softness of the squeegee.
