Abstract
An umbrella operating system allows for the simple opening, closing and locking of an umbrella while allowing the frame to freely rotate about the pole, wherein the pole is held in a stationary position. The umbrella includes a pair of hub members mounted about a pole member wherein the lower hub member is slidable up and down the pole. A pulley system with locking cam member may be employed to allow the umbrella to safely and easily open to any desired level. A locking stabilizer arm may be used to secure the main hub member in the fully open position and a stabilizer base provides strong support to the pole member to help it withstand severe weather conditions. The umbrella is rotatable about the pole axis regardless of the degree to which it is opened.
Claims12
An umbrella, comprising:
- a central pole member having a longitudinal axis and top and bottom ends;
- a main hub member secured about said central pole member, said main hub member capable of sliding between said bottom and said top ends and including a top surface and a side surface;
- a secondary hub member secured to said pole member near said pole top end;
- means for supporting a canopy member;
- pulley means comprising at least one pulley member secured to said secondary hub member for raising and lowering said main hub member along said pole member;
- a bracket member secured to said top surface of said main hub member, and a line member having first and second ends, said first end being secured to said bracket member, said line member cooperatively engaging said pulley member and extending downwardly from said pulley member towards said pole member bottom end;
- means for securing said main hub member in a stationary position along said pole member;
- said securing means comprising a cam member secured to said side surface of said main hub member;
- and wherein said line member cooperatively engages said cam member as it extends downwardly from said pulley member.
