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.
Claims21
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 including a distal rib, 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 rib joint that is coupled to first and second ribs of the plurality of 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;
- wherein 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 coupled to the first rib joint;
- wherein the bent clip portion is bent such that the first end of the wire travels in a longitudinal direction away from the first rib and travels along but spaced apart from a length of the wire that is adjacent the bent clip potion of the wire;
- wherein the wire comprises a metal wire and the bent clip portion comprises a biased spring clip.
