Retractable umbrella

A retractable umbrella comprising:

• a tubular shaft, having a top end and a bottom end;
• wherein:
• an inside surface of said tubular shaft is provided with a plurality of longitudinal grooves spaced equidistant from each other beginning at said top end and extending a majority of a length of said tubular shaft;
• and,
• a plurality of canted grooves are spaced equidistant from each other existing only at said top end, positioned at interstitial locations of said longitudinal grooves, forming crenels at said top end;
• a worm gear situated within said tubular shaft, wherein:
• said worm gear is provided with a central shaft, provided with a helical flight uniformly disposed upon an outside diameter thereof;
• and,
• a landing is located at an upper portion of said central shaft;
• a rib pivot assembly located within said tubular shaft and slidably movable along a longitudinal length of said tubular shaft inside surface, wherein:
• said rib pivot assembly is provided with a core;
• said core is provided with a flight at a central portion thereof to receive and facilitate rotational motion of said worm gear and to enable said core to traverse said tubular shaft in a longitudinal direction;
• said rib pivot assembly is provided with a wheel pivot top, comprising:
• a first perimeter edge having a plurality of first teeth in a coinciding and complementary profile with said longitudinal grooves;
• a first center provided with a first aperture complementary in profile to receive said core;
• and,
• wherein a bottom surface of each of said first teeth is provided with a first receiving channel;
• said rib pivot assembly is provided with a wheel pivot bottom, comprising:
• a second perimeter edge having a plurality of second teeth in a coinciding and complementary profile with said longitudinal grooves;
• a second center provided with a second aperture complimentary in profile to receive said core;
• wherein a top surface of each of said second teeth provided with a second receiving channel;
• and,
• said rib pivot assembly is provided with a wheel rotating ring comprising an annulus that fits within said first and second receiving channels;
• said rib pivot assembly is provided with a wheel base, comprising:
• a third perimeter edge having a plurality of third teeth in a coinciding and complementary profile with said longitudinal groves;
• and,
• a third center provided with a third aperture complimentary in profile to receive said core;
• a plurality of ribs extending from said rib pivot assembly, wherein:
• each rib is a semi-rigid, flexible material, having a first end and a second end;
• each first end is provided with an engaging member to attach to said wheel rotating ring;
• and,
• each second end has a torus at a terminus thereof;
• a canopy fastened to each rib;
• a floating cap threadingly attached to an upper portion of said worm gear configured such that a gap is maintained between said floating cap and said tubular shaft;
• a first compartment, wherein:
• said first compartment is a first chamber adapted to hold at least one battery;
• said first compartment is provided with electrical connectors;
• said first compartment is provided with a top end thereof to removably secure said first compartment to said bottom end of said tubular shaft;
• and,
• said first compartment is provided with a bottom end thereof;
• a second compartment, wherein:
• said second compartment is a second chamber adapted to hold at least one battery;
• said second compartment is provided with a top end thereof, thereby dividing said second compartment from said first compartment bottom end;
• and,
• said second compartment is provided with a threaded configuration at a bottom end thereof;
• a cap removably secured to said bottom end of said second compartment;
• a driving means for operably moving said rib pivot assembly;
• and,
• wherein said core, said wheel pivot top, said wheel pivot bottom, said wheel rotating ring, and said wheel base are affixed to each other to align each of said first, second, and third teeth.
