Claims9

Dependent claims

An umbrella comprising in combination:

a vertical shaft having a top end and a lower end defined at the opposite extremity thereof;
a first rib disc and a second rib disc attached coaxially therewith for defining therebetween a plurality of rib ball receptacles each having a downwardly, outwardly and radially extending slot coupled thereto, with said first and second rib discs each having a central aperture coaxially therein for having said vertical shaft coupled therethrough adjacent said top end thereof;
a plurality of substantially equally spaced ribs each having a rib ball attached to one end thereof for movably coupling within one of said rib ball receptacles, with each of said ribs communicating through one of said radially extending slots for coupling within said first and second rib discs, whereby each of said ribs may collapsibly fold along and be extended from said vertical shaft;
a first support disc and a second support disc juxtaposed coaxially therewith for defining therebetween a plurality of support ball receptacles each having an upwardly and outwardly extending slot coupled thereto, within said first and second support disc each having a central aperture coaxially therein for movably receiving said first vertical shaft therethrough, whereby said first and second support discs move longitudinally along said vertical shaft as said umbrella is collapsibly folded;
a detachable cover coupled at a central portion thereof to said top end of said vertical shaft;
a plurality of support ribs for providing a bowing force on each of said ribs, with a first end of each of said support ribs including thereon a support ball for being movably restrained within one of said support ball receptacles defined by said first and second support discs, a second end of each of said support ribs movably connected to one of said ribs intermediate said end of said ribs;
a detachable cover coupled at a central portion thereof to said top end of said vertical shaft;
a first fabric coupler attached to a distended end of each of said ribs and a second fabric coupler attached to a circumferential edge section of said attachable cover and extending radially beyond said edge section a sufficient dimension to be folded back under said distended end of one of said ribs, each of said first fabric couplers juxtaposed with and removably coupled to one of said second fabric couplers for stretching said detachable cover over said plurality of ribs.
