Abstract
A sucker being diversified and/or improved and/or more endurable and/or more effective and/or convenient and/or multi-functional and/or more efficient is provided. The sucker includes a downwardly concave sucking body to be pressed against an attaching surface to vacuumize the room defined therebetween, a downwardly concave resilient member superimprosed above the sucking body and having an outer periphery and a plurality of grooves not beginning from the periphery, and a connector connecting together the sucking body and the resilient member in the manner that after the sucking body has been pressed against the attaching surface, the resilient member will tend to urge the sucking body away from the attaching surface which will in turn result in that the sucking body is more securely attached to the attaching surface.
Claims20
A suction cup device comprising:
- a downwardly concave sucking body having a first central portion and adapted to be downwardly pressed against an attaching surface to vacuumize a space defined between said sucking body and said attaching surface in order that said sucking body can thus be attached to said attaching surface;
- a downwardly concave resilient member superimposed above said sucking body, and having a second central portion, an outer periphery and a plurality of grooves spaced from said periphery;
- and
- a connector connecting together said first and second central portions in a manner that after said sucking body has been pressed against said attaching surface, said resilient member will tend to urge said sucking body away from said attaching surface which will in turn result in that said sucking body is more effectively attached to said attaching surface.
