Definitions

  • the present invention relates to an umbrella structure, and more particularly to an improved frame for an umbrella resistant to wind-induced damage.
  • a support rib is directly hinged to an intermediate element along a main rib supporting an umbrella fabric.
  • Use of such umbrellas during windy weather often results in eversion-induced damage to the frame supporting the umbrella fabric.
  • the prior art includes a design intended to avoid wind-induced damage wherein a short connecting rod is disposed between and connected to a main rib and a support rib.
  • the connecting rod provides a cushioning force at the main rib to avoid damage to the frame, thus extending the useful life of an umbrella.
  • both ends of the connecting rod are connected respectively to the main rib and the support rib via rivets.
  • This design feature complicates assembly.
  • this design feature is complex and costly.
  • this design feature remains susceptible to wind-induced damage.
  • An object of the present invention is to provide a windproof umbrella frame that that avoids the limitations of the prior art.
  • a further object of the present invention is to provide a windproof umbrella frame that simplifies assembly, reduces cost, and is robust.
  • the invention includes a main rib supporting an umbrella fabric, a support rib, and a connecting rod disposed between the support rib and the main rib.
  • the main rib includes a center plate centrally disposed thereon.
  • the support rib includes a support rib joint at an end thereof.
  • One end of the connecting rod is hingedly connected to the center plate and another end of the connecting rod is integrally molded to the support rib joint.
  • the support rib joint is connected to the connecting rod via a flexible soft plastic segment.
  • the soft plastic segment includes a tab that extends radially outward therefrom.
  • the center plate includes a clamping portion and a catch fixed to and extending from the clamping portion.
  • the clamping portion includes a clamping slot for receiving the main rib.
  • the clamping slot is less wide than the main rib so that the clamping slot mechanically secures the center plate to the main rib.
  • the connecting rod includes a through hole. The catch engages the through hole.
  • the connecting rod and the center plate are secured via a rivet.
  • the connecting rod is provided with a seating depression along one side toward the main rib.
  • Exemplary advantages of the invention include the following.
  • the integral connection between connecting rod and support rib via a flexible soft plastic segment provides an assembly that simplifies assembly, reduces cost, and is robust.
  • FIG. 1 is a perspective view illustrating features of the invention when the main rib of the windproof umbrella frame is properly configured in accordance with an embodiment of the invention.
  • FIG. 2 is a perspective view illustrating features of the invention when the main rib of the windproof umbrella frame is deformed by wind loading in accordance with an embodiment of the invention.
  • FIG. 3 is an exploded view illustrating features of the invention wherein the center plate includes a catch configured to engage a through hole along the connecting rod in accordance with an embodiment of the invention.
  • FIG. 4 is an exploded view illustrating features of the invention wherein the center plate and connecting rod are connectable via a rivet in accordance with an embodiment of the invention.
  • FIG. 5 is an enlarged perspective view illustrating design features of the connecting rod, support rib joint, soft plastic segment, seating depression, and tab in accordance with an embodiment of the invention.
  • the windproof umbrella frame includes a main rib 1 , a support rib 2 and a connecting rod 3 .
  • the main rib 1 supports an umbrella fabric.
  • the support rib 2 supports the main rib 1 .
  • the connecting rod 3 is disposed between and connected to an outer end of the support rib 2 and the main rib 1 .
  • a center plate 5 is disposed along the central portion of the main rib 1 .
  • the support rib 2 is provided with a support rib joint 6 disposed along an outer end.
  • the connecting rod 3 is hinged to the center plate 5 of the main rib 1 at one end and integrally molded with the support rib joint 6 at another end, the latter illustrated in FIG. 5 .
  • the support rib joint 6 is connected to the connecting rod 3 via a flexible soft plastic segment 31 .
  • the integrally molded structure avoids the need for rivets, yet facilitates a simple, convenient, low cost, robust, and reliable assembly.
  • the soft plastic segment 31 includes a tab 34 disposed radially outward from the outer side of the soft plastic segment 31 . This arrangement ensures that the soft plastic segment 31 of the connecting rod 3 moves radially outward when an umbrella is opened, so that the connecting rod 3 is inversely folded without bending toward the opposing inside.
  • the connecting rod 3 and the center plate 5 may be hinged as described below.
  • the center plate 5 includes a clamping portion 51 and a catch 52 fixed to the bottom end of the clamping portion 51 .
  • the clamping portion 51 is provided with a clamping slot 53 configured to receive the main rib 1 along a top surface.
  • the width of the opening along the clamping slot 53 is slightly smaller than the diameter of the main rib 1 .
  • One end of the connecting rod 3 is provided with a through hole 32 .
  • the through hole 32 is configured to receive the catch 52 , thus enabling the catch 52 to be secured to the connecting rod 3 .
  • the catch 52 When assembled, the catch 52 passes through the through hole 32 adjacent to one end of the connecting rod 3 and the main rib 1 is pressed into and locked within the clamping slot 53 , so as to provide a rivet-less hinge between the connecting rod 3 and the main rib 1 .
  • the catch 52 abuts the main rib 1 so that the connecting rod 3 does not separate from the center plate 5 .
  • center plate 5 and the connecting rod 3 are hingedly connected via rivets.
  • the center plate 5 and connecting rod 3 include holes that mutually align to facilitate secured attachment of a rivet through both structures.
  • the connecting rod 3 is provided with a seating depression 33 along the side directed toward the main rib 1 .
  • the main rib 1 seats onto the seating depression 33 , thereby increasing the positional stability of the main rib 1 and reducing the volume of the umbrella.
  • the main rib 1 with the umbrella fabric could possibly reverse outward when wind loads contact the inner surface of the umbrella; however, the connecting rod 3 connected to the main rib 1 would correspondingly rotate, and the position of which would move upward, largely buffering the force at the junction between both the connecting rod 3 and the main rib 1 , thereby increasing the operational life of the frame.
