Suction cup for attachment to e.g. vehicle windshield, has additional cams formed at pivot of lever and pressed against catch of cover to enable suction disc to be pressed down by cover

摘要

A connecting link (30) on the center of a suction disk (20) penetrates through a central opening (12) on a cover (10) and connects the pivot (42) of a lever (40). The pivot forms main and additional cams (43,44). When the push part (41) of the lever is pressed, the additional cams engage against the catch (14) on the cover, enabling the cover to lightly press down the suction disk.
