Claims23
An umbrella base, comprising:
- a first support configured to be coupled to a fixed base or ground support, the first support comprising a plurality of enclosed apertures extending from a first opening on a top surface of the first support to a second opening on a bottom surface of the first support;
- a second support rotatably coupled to the first support;
- an actuator pivotably coupled to the second support, the actuator comprising:
- a foot pedal disposed at a first end;
- and
- a pin disposed at a second end of the actuator opposite the foot pedal, the pin having a free end disposed away from the second end of the actuator and a fixed end removably coupled to the second end of the actuator whereby the pin can be removed from the actuator without removing the actuator from the second support;
- and
- a spring disposed between the foot pedal and the second support, the spring being configured to bias the pin into any one of the plurality of enclosed apertures;
- wherein, in use, depressing the foot pedal retracts the pin from any one of the plurality of enclosed apertures and raising the foot pedal returns the pin into one of the plurality of enclosed apertures.

An umbrella base, comprising:
- a first support configured to be coupled to a fixed base or ground support, the first support comprising a plurality of apertures extending from an opening on a surface of the first support;
- a second support rotatably coupled to the first support;
- an actuator pivotably coupled to the second support, the actuator comprising:
- a controller disposed at a first end;
- and
- a pin assembly disposed at a second end of the actuator opposite the controller, the pin assembly including a pin having a free end disposed away from the second end of the actuator and a fixed end secured to the second end of the actuator by a clip, the fixed end of the pin positioned above the second support;
- wherein the controller is configured to retract the free end of the pin from any one of the plurality of apertures;
- wherein the controller is configured to insert the free end of the pin into any one of the plurality of apertures;
- wherein the clip comprises a slot, the slot configured to receive a notch on the fixed end of the pin.
6 more elements
An umbrella base, comprising:
- a first support configured to be coupled to a fixed base, the first support comprising a plurality of apertures extending from an opening on a surface of the first support;
- a second support rotatably coupled to the first support, the second support including a slot;
- an actuator coupled with the second support, the actuator comprising:
- a first portion;
- and
- a second portion disposed away from the first portion;
- a pin assembly disposed at the second portion, the pin assembly including a pin having a free end disposed away from the second portion of the actuator, the pin being secured to the second portion of the actuator by a removable clip;
- wherein lowering the first portion retracts the free end of the pin from any one of the plurality of apertures and allows rotation of the second support relative to the first support;
- wherein raising the first portion with the slot vertically aligned above any one of the plurality of apertures inserts the free end of the pin into any one of the plurality of apertures by extension through the slot and prevents rotation of the second support relative to the first support;
- wherein the actuator comprises a ring shaped body having an inner periphery configured to be disposed outward of and surround an umbrella pole when the umbrella base is coupled with an umbrella pole.
