Abstract
An umbrella includes an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella. The anti-inversion mechanism includes a flexible elongated structure that is disposed exteriorly along the second rib part and has a first bent end that is attached to the second rib part by passing through an opening formed in the second rib part and being anchored within a hollow interior of the second rib part. The mechanism further includes a flexible wire having a first end attached to the flexible elongated structure of the anti-inversion mechanism and a second end attached to a rib tip that is located at a free distal end of the rib assembly.
Claims19
An umbrella comprising:
- an elongated shaft having a first end and an opposite second end;
- a runner slidably disposed about the elongated shaft;
- and
- a plurality of rib assemblies, each rib assembly including a first rib part, a second rib part and a third rib part, the rib assembly being attached to the runner by a strut that moves between open and closed positions in which in the open position, the first, second and third rib parts are in an open, extended position and in the closed position, the first, second and third rib parts are in a closed, collapsed position;
- an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella, the anti-inversion mechanism including a first flexible elongated structure that is disposed exteriorly along the second rib part and has a first bent end that is attached to the second rib part by passing through an opening formed in the second rib part and being anchored within a hollow interior of the second rib part;
- and
- a second flexible elongated structure having a first end attached to the first flexible elongated structure of the anti-inversion mechanism and a second end attached to the third rib.

- an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella, the anti-inversion mechanism including an flexible elongated wire that is disposed exteriorly along the second rib part and has a first bent end that is attached to the second rib part at a location spaced inward from a first end of the second rib at which the second rib directly attaches to the first rib;
- and
- a flexible elongated structure wife-having a first end attached to the flexible elongated wire of the anti-inversion mechanism and a second end attached to the third rib.
