Umbrella having a pivot joint to provide additional degrees of freedom of orientation of its canopy
Abstract:
An umbrella having the crown of the canopy coupled to a support structure via a pivot joint that is structured and configured to allow swiveling and/or tilting of the canopy with ease by a user, in more than one plane or with more than one degree of freedom with respect to the support structure. The canopy frame includes a longitudinal central support hub, and the pivot joint is rotatable about a rotation axis, wherein the axis of the canopy support hub makes a fixed or variable non-zero angle with respect to the pivot joint rotation axis. As a result of the angle between the pivot joint rotation axis and the canopy support hub axis. The rotation of the pivot joint causes tilting of the canopy support hub axis, thus tilting the canopy to change its orientation.
