Abstract
An cantilever umbrella (100) comprises a base (102), post (101), cantilever arm (103) and a canopy (106) that is supported on a hub (104) with radial arms (105). The canopy (106) can pivot about an axis parallel to the cantilever arm (103) by pivoting the hub (104) relative to the cantilever arm. The umbrella (100) is protected against excess wind by pivoting outer parts (202) of the radial arms (105) upwards, but holding the outer parts (202) down with tension in the canopy (106) during normal use. A concealed, self-aligning angle bracket (300) is used to attach an upper end (302) of the post (101) to a proximal end (303) of the cantilever arm (103).
Claims11
An umbrella comprising:
- a hub;
- a plurality of radial arms extending from the hub;
- a canopy;
- an upright post;
- a cantilever arm extending from the post to the hub with the canopy supported directly on top of the cantilever arm and radial arms;
- wherein the hub is pivotally attached to the cantilever arm, to pivot about a pivot axis that is aligned with the cantilever arm;
- wherein the umbrella is a radially opening umbrella and at least some of the radial arms are pivotally attached to the hub to pivot about upright axes along a conical plane of the canopy;
- wherein the pivot axis and at least part of the cantilever arm are aligned with the conical plane of the canopy;
- wherein the umbrella includes a latch mechanism that is displaceable between a free condition in which the hub is free to pivot about the pivot axis, and a latch condition in which the hub is held against pivoting about the pivot axis, said latch mechanism including a latch pin that is contained inside the cantilever arm and that is displaceable parallel to the pivot axis, to engage the hub;
- and
- wherein the umbrella includes a bar that is supported on the cantilever arm and that is manually operable from the proximity of the post to displace the bar along the cantilever arm to operate the latch mechanism between the free condition and the latch condition;
- wherein said umbrella includes a lock mechanism including a stop formation that is supported on the cantilever arm in the proximity of the post, an end of the bar that faces towards the post being displaceable in the lock mechanism in a linear direction that is purely transverse to the pivot axis that is aligned with the cantilever arm, between a free position in which the bar can move longitudinally along the cantilever arm, and a lock position in which the end of the bar that faces towards the post buts against the stop formation so that the bar is prevented from longitudinal movement along the cantilever arm in a direction away from the hub, and the bar presses the latch pin towards the hub, and wherein the end of the bar that faces towards the post is biased in the direction transverse to the cantilever arm to the lock position, a default position.
