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 first rib joint that is coupled to first and second ribs, a first elongated member that is coupled to the first rib joint and a second elongated member that is coupled to the first elongated member and to the distal rib. The first rib joint includes an inner slot and the first elongated member comprises a wire having a bent clip portion at a first end of the wire, the bent clip portion being received within the inner slot and being biased against a floor of the inner slot resulting in the wire being attached to the first rib joint.
Claims23
An umbrella comprising:
- an elongated shaft having a first end and an opposite second end;
- a runner slidably disposed about the elongated shaft;
- a plurality of rib assemblies, each rib assembly including a plurality of ribs with a rib joint connecting two ribs of the plurality of ribs, 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 plurality of ribs are in an open, extended position and in the closed position, the plurality of ribs are in a closed, collapsed position;
- and
- 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 elongated member that is coupled to the rib joint and a second elongated member that is coupled to the first elongated member and to one rib of the plurality of ribs;
- wherein the rib joint includes an inner slot and the first elongated member comprises a wire having a bent clip portion at a first end of the wire, the bent clip portion having a curved end section and an angled end section that extends from the curved end section, the angled end section having a bend along a length thereof and being located above another section of the wire and extending in a direction away from the curved end section toward the second elongated member, the bent clip section being received within the inner slot and being biased such that the angled end section is biased and seats against a floor of the inner slot resulting in the wire being coupled to the rib joint.
