Patent ID: 7690610

Claim:
A suction-cup holding device ( 1 ) for fixing on fastening surfaces ( 17 ), comprising a hollow suction base ( 2 ) which is open towards the fastening surface ( 17 ) and is provided with a central piece ( 11 ) and a sealing edge ( 5 ) which comprises an elastic material at least towards the fastening surface ( 17 ) and with which the suction base ( 2 ) can be placed on the fastening surface ( 17 ) so that an outwardly gas-fight sealed suction chamber ( 30 ) is formed between the underside ( 9 ) of the suction base ( 2 ) and the fastening surface ( 17 ), the suction-cup holding device ( 1 ) comprises contact pressure transmitters ( 8 ) which are elastically deformable in the direction of the pressure applied and are located between the central piece ( 11 ) of the suction base ( 2 ) and the outer sealing edge ( 5 ′) on the suction base—at a distance from the central piece ( 11 ) and from the outer sealing edge ( 5 ′) in each case—on the outer side ( 6 ) of the suction base wall ( 7 ), and the suction-cup holding device ( 1 ) comprises a pressing means ( 18 ) for transferring the contact pressure to the suction base wall ( 7 ), wherein the pressing means ( 18 ) is configured in such a manner that at least under the contact pressure exerted on the central piece ( 11 ) in the direction of the fastening surface ( 17 ), said means is in communication with the central piece ( 11 ), the contact pressure transmitter(s) ( 8 ) and via said contact pressure transmitter(s) ( 8 ), with the suction base wall ( 7 ), wherein the pressing means ( 18 ) which is formed to be able to put pressure from outside against the suction base wall ( 7 ) of the suction base ( 2 ), comprises of a cover secured to the central piece ( 11 ), which acts on the contact pressure transmitter(s) ( 8 ) at least under contact pressure, wherein a stabilizing framework ( 10 ) with arms ( 13 ) emanating from the central piece ( 11 ) is embedded in the material of the suction base ( 2 ) or is placed thereon and the arms ( 13 ) cover at least half the radius of the suction base ( 2 ) and can be bent resiliently.
