Hub assembly for an umbrella frame

An umbrella frame comprising:

• a pole member having a longitudinal axis, a bottom end and a top end, said pole member also having a retaining pin slot extending therethrough;
• a main hub member secured about said central pole member, said main hub member capable of sliding between said bottom and said top ends, said main hub member also capable of rotating about the axis of said pole member,
• said main hub member having an upper portion and a lower portion and a band secured about a periphery thereof between said upper and lower portions,
• a plurality of brackets secured to said band and hub member,
• a secondary hub member secured to said pole member near said pole top end, said secondary hub member also capable of rotating about said central pole axis,
• a plurality of rib members pivotally secured to said secondary hub member,
• a plurality of strut members each having an inner and an outer end, said inner ends being pivotally secured to said brackets on said main hub member respectively, said outer end of each of said strut members being pivotally secured to a respective one of said rib members,
• a pin member extendable within said retaining pin slot for maintaining said main hub member in position along said pole member, and
• means for securing said pin member to said main hub member so as to allow said umbrella frame to rotate freely about said pole member when said pin member is placed within said retaining pin slot.

A hub assembly for an umbrella frame comprising:

• a hub member having a central aperture sized to receive a pole member of the umbrella frame, said hub member being capable of sliding between a bottom end and a top end of the pole member,
• said hub member having an upper portion and a lower portion,
• a band secured to said hub member about a periphery thereof between said upper and lower portions,
• a channel formed generally in said upper portion, said channel being defined by at least a lower ledge extending about a periphery of said hub member, and wherein said band is secured to said hub member about said channel, and
• a plurality of brackets disposed within said channel in overlying relation to said band and fixedly secured to said hub member, wherein said brackets are structured to pivotally receive an end of a strut member of the umbrella frame.

A hub assembly in combination with an umbrella frame having a pole member comprising:

• a hub member having a central aperture sized to receive the pole member of the umbrella frame,
• said hub member movably mounted on the pole member and slidable along a length thereof between a bottom end and a top end thereof,
• said hub member having an upper portion and a lower portion,
• a channel continuously disposed on said hub member and extending about an exterior peripheral surface thereof,
• said channel being defined by an upper ledge and a lower ledge projected outwardly from said exterior periphery surface of said hub member,
• a plurality of brackets disposed within said channel and fixedly connected to said hub member so as to prevent rotational movement of said brackets, and
• said plurality of brackets pivotally connected to end
• said channel being defined by an upper ledge and a lower ledge projected outwardly from said exterior periphery surface of said hub member, portions of a plurality of strut members of the umbrella frame.
