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.
Claims16
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 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 a bottom surface of the second rib part at a location that is spaced distally from a proximal end of the second rib part, the first bent end being anchored within a hollow interior of the second rib part;
- and
- 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, wherein the bottom surface of the second rib part is a surface that faces a main portion of the flexible elongated structure that is adjacent the first bent end, the main portion of the flexible elongated structure extending to a second distal end that attaches to the flexible wire.
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 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 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;
- a first canopy and a second canopy that overlies a center opening formed in the first canopy to provide a vent therebetween, the first canopy extending radially beyond the second canopy, wherein the third rib part is attached to the first canopy and a wire coupling member is attached between the second canopy and a rib joint that pivotally attaches the second rib part to the third rib part;
- wherein the wire coupling member comprises a wire that has a first end attached to the rib joint and a length that extends along the second rib part and passes through a first coupler that is part of first rib part and attaches at an opposing second end to the second canopy.
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 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 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;
- wherein the second rib part comprises a metal C-shaped structure that is disposed between the first rib part and the third rib part which comprises a distalmost rib of the rib assembly, the metal C-shaped structure being defined by a pair of opposing parallel side walls and a connector wall that extends between and connects to the opposing parallel side walls, the flexible elongated structure comprising a metal wire that is only attached to the second rib part at the bent first end so as to form a cantilevered structure, the bent first end being in contact with the connector wall that is arranged so as to directly face the third rib part in the closed position.
