| 摘要 | An umbrella base is provided that includes a first support, a second support and a control device, which can include a foot pedal. The second support is rotatably coupled with the first support. The foot pedal is coupled with the first support, e.g., at a pivot. The foot pedal has at least one lateral member. The lateral member projects downward from an arm. The lateral member is located on the same side of the second support as the foot pedal. Movement of the foot pedal downward causes lateral members to disengage from the second support permitting the second support to rotate. | ||||||
