  • Publication number: 20020134904
    Abstract: A multi-functional adjustable base for a sun shading umbrella having a supporting stem includes a base support, a stem rotary member rotatably supported by the base support and securely holds the supporting stem, and a controlling arrangement mounted on the base support and communicated with the stem rotary member for selectively rotating or locking up the stem rotary member. The controlling arrangement includes a transmission member, which is supported by the base support, having an engaging end adapted for engaging with the stem rotary member, and a paddle pivotally and integrally connected to the transmission member and extended outside the base support for switching the stem rotary member into one of the two states—a freely rotating state and a locked state, wherein in the freely rotating state, the stem rotary member is free to rotate with respect to the base support, while in the locked state, the stem rotary member is locked in position.
