Abstract
The flexible cord used to erect the umbrella from the top, passes through a cantilever tube, the inner end of which is removably supported in a bracket. A notch in the bracket tensions the canopy and locks the umbrella to the bracket by catching a bead fixed on the cord. Three ways of supporting the bracket are shown, as is a way of storing the device.
Claims14
A top-erected umbrella with cantilevered support, comprising:
- an umbrella canopy of flexible sheet material mounted to an umbrella frame having a plurality of ribs radiating from pivotal connection to a frame ring;
- the umbrella canopy having an apical opening in axial superimposed alignment with the frame ring;
- an anchor tube under said canopy in axial alignment with said frame ring;
- the umbrella frame further having a plurality of radiating stretchers, each having one end pivotally mounted to the anchor tube and another end pivotally mounted to a respective rib, so that moving the anchor tube axially towards the frame ring will cause the canopy to be raised to an erected condition from a collapsed condition;
- an erector rope sub-unit comprising a rope having a first enlargement provided on a first, outer end thereof, anchor sleeve means threaded on said rope and disposed adjacent said first enlargement, said anchor sleeve means having an upper portion of reduced diameter, providing a guide finger having a shoulder at the base thereof;
- a tubular clamp strung on said rope above said anchor sleeve and having a lower tubular portion and an upper tubular portion, each portion having a clamping jaw, the two clamping jaws being in axially confronting relation;
- means for securing the two clamp portions together so that the two clamping jaws are in clamping relation;
- means providing a second enlargement on the second inner end of said rope, said lower tubular portion of said tubular clamp having downwardly opening throughbore means arranged to slidingly telescopingly receive said guide finger of said anchor sleeve;
- and an enlarged bead fixed on said rope at a predetermined distance therealong which is further toward said second end than is said tubular clamp;
- a bracket tube having an open longitudinal bore and having a notch in the lower end thereof;
- and means for securely mounting said bracket tube in a generally upright, elevated condition;
- a swing tube having a substantial lateral extent and two opposite, generally downwardly directed ends comprising an inner end an an outer end;
- said rope being threaded through said umbrella frame and swing tube, so that said first end lies adjacent said anchor tube of said frame and said second end lies accessable below the inner end of the swing tub;
- means securing the anchor tube to the anchor sleeve means;
- the clamp being assembled through said canopy apical opening and said frame ring so that said canopy and frame are clamped between said clamp jaws and so that an upstanding peg portion of said clamp rises from the top of said canopy;
- for erecting and mounting the umbrella, the outer end of the swing tube being telescoped with said upstanding peg, the inner end of the swing tube being telescoped with the bracket tube so that the inner end of the rope lies exposed below the bracket tube, and the inner end of the rope being pulled down until said bead has emerged downwards through the bracket tube, whereupon the inner end of the rope has been pulled laterally to pull the rope just above the bead into said notch in the lower end of the guide tube.
