Umbrella

摘要

Umbrella assemblies described herein are advantageously configured with simple yet robust arrangements for securing an umbrella in an open configuration, for example, with a runner in an elevated position. In some embodiments, the umbrella assemblies are self-opening and/or include locking devices. The locking devices can engage support structures positioned on an umbrella pole.

主权项

1. An umbrella, comprising:
a pole having an upper end and a lower end, and extending along a longitudinal axis; 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 in a closed configuration and an upper position in which the umbrella is an open configuration; a plurality of support members connected to the hub and runner; a support protrusion extending outwardly from and rigidly attached to an outside surface of the pole, the support protrusion extending along a direction substantially perpendicular and intersecting the longitudinal axis of the pole; and a locking device pivotally mounted on the runner, the locking device disposed radially inward of an outer periphery of the runner, the locking device comprising an engagement portion extending outwardly and movable toward the pole to engage with the support protrusion to maintain the runner in the upper position and movable away from the pole to disengage from the support protrusion to permit the runner to slide from the upper position to the lower position, the locking device being configured to operate about a pivot axis, the pivot axis being disposed below and extending transversely to the direction of the support protrusion when the engagement portion is engaged with the support protrusion.
