Abstract
Umbrella assemblies described herein are advantageously configured to with simple yet robust arrangements for securing an umbrella in an open configuration, e.g., with a runner in an elevated position.
Claims20
An umbrella, comprising:
- a pole having an upper end and a lower end;
- an upper hub coupled with the upper end of the pole;
- a runner disposed beneath the upper hub and coupled with the pole to slide between a lower position in which the umbrella is closed and an upper position in which the umbrella is open;
- a plurality of support members connected to the hub and runner;
- a support structure disposed on the pole;
- and
- a locking device mounted on the runner, the locking device configured to engage the support structure to maintain the runner in the upper position and to disengage from the support structure to permit the runner to slide from the upper position to the lower position.

An umbrella, comprising:
- a pole having an upper end and a lower end;
- an upper hub coupled with the upper end of the pole;
- a runner disposed beneath the upper hub and coupled with the pole;
- a plurality of ribs coupled with the upper hub;
- and
- a plurality of struts extending between the ribs and the runner;
- wherein the umbrella comprises an open configuration in which the runner is elevated and a canopy is disposed over the ribs and a closed configuration in which the runner is lowered, the umbrella having an inflection point along the range of travel of the runner from the closed configuration to the open configuration in which net forces applied by the struts to the runner switch direction from a downward net force to an upward net force;
- wherein when the runner is released at the inflection point, the upward net force causes the runner to travel upward to the open position without further user interaction;
- and
- a locking device mounted on the runner, the locking device configured to prevent the umbrella from unintentionally switching from the open configuration to the closed configuration.

- a runner disposed beneath the upper hub and coupled with the pole to slide between a lower position in which the umbrella is closed and an upper position in which the umbrella is open;
- a support structure disposed on the pole;
- and
- a locking device mounted on the runner, the locking device configured to engage the support structure to maintain the runner in the upper position and to disengage from the support structure to permit the runner to slide from the upper position to the lower position, wherein a collar is provided over the locking device, the collar having an inner surface that engages the locking device to move the locking device from engaged to disengaged positions.
