Abstract

An arthritic-aiding pin-centering-and-guiding auditorily-snap-locking umbrella comprising: a canopy having tension-adjusting oval openings, a pole having a fixed hub and a movable hub, tension-adjusting rods, rod-locking screws respectively screwed through the tension-adjusting oval openings and into the tension-adjusting rod, three pulleys respectively screwed to the fixed hub and the movable hub, a pulley cord threaded on the three pulleys and attached to the movable hub, a cord hook, two gear cams attached to the movable hub, a cord blocker attached to the two gear cams, at least one pin opening drilled through the pole, an arthritic-aiding grip ring attached to the cord hook, a locking pin attached to the arthritic-aiding grip ring, a recess molded on the locking pin, at least one pin-centering-and-guiding plug and tube having built-in auditorily-snap-locking leaf springs and leaf-spring towers inserted into the pole and aligned with the at least one pin opening, and a tower-locking screw screwed between the leaf-spring towers for locking the plug inside the pole.

First claim

What is claimed is:

1. An arthritic-aiding pin-guiding auditorily-snap-locking umbrella comprising:
a canopy and pole system comprising:
a canopy, said canopy having a plurality of canopy openings,
a plurality of upper ribs, each of said upper ribs having a rib tip,
a plurality of lower ribs,
a plurality of foldable rib joints respectively attached to said upper ribs and pivotably attached to said lower ribs,
an umbrella pole, said umbrella pole having a pole top,
a fixed inner hub attached to said pole top,
a fixed outer hub molded to said fixed inner hub and pivotably screwed to said upper ribs,
a movable inner hub movably slid on said umbrella pole,
a movable outer hub molded to said movable inner hub and pivotably screwed to said lower ribs, and
a movable tubular elevator screwed to said movable inner hub;

a canopy-tension-adjusting system comprising:
a plurality of protracting-rod-locking washers,
a plurality of tension-adjusting oval rib openings respectively drilled in said upper ribs,
a plurality of externally-threaded protracting rods respectively inserted into said rib tip of said upper ribs,
a plurality of threaded rod openings respectively drilled in said externally-threaded protracting rods,
a plurality of internally-threaded tension-adjusting knobs respectively screwed on said externally-threaded protracting rods, and
a plurality of protracting-rod-locking screws respectively screwed through said protracting-rod-locking washers, through said canopy openings, through said tension-adjusting oval rib openings, and into said threaded rod openings
for tensioning said canopy;

an arthritic-aiding tri-pulley system comprising:
two fixed-hub pulleys respectively screwed to said fixed outer hub,
a movable-hub pulley screwed to said movable outer hub,
a pulley cord threaded on said two fixed-hub pulleys and said movable-hub pulley, and attached to said movable outer hub, and
a cord hook
for said pulley cord to be releasably hooked thereon;

an anti-cable-fraying cable-locking gear-cam system comprising:
a gear-cam mount screwed to said movable tubular elevator,
two gear cams each having a tear-dropped shape
for clampingly securing said pulley cord therebetween and allowing said pulley cord to move in only one direction therebetween,

a cord blocker, and
two gear-cam screws respectively screwed through said cord blocker, through said two gear cams, and onto said gear-cam mount; and

an arthritic-aiding pin-centering-and-guiding auditorily-snap-locking tower-locking system comprising:
at least one pin opening respectively drilled through said umbrella pole,
an arthritic-aiding grip ring attached to said cord hook for aiding an arthritic use,
an anti-finger-pinching spacer screwed on said cord hook,
a locking pin molded to said anti-finger-pinching spacer,
an auditorily-snap-locking recess molded on said locking pin,
at least one pin-centering-and-guiding plug inserted into said umbrella pole,
at least one pin-centering-and-guiding tube molded inside said at least one pin-centering-and-guiding plug and aligned with said at least one pin opening
for centering said locking pin inside said at least one pin-centering-and-guiding tube and
for guiding said locking pin through said at least one pin opening,

a plurality of auditorily-snap-locking leaf springs molded inside said at least one pin-centering-and-guiding tube,
a plurality of auditorily-snap-locking nipples respectively molded on said auditorily-snap-locking leaf springs
for auditorily-snap-locking inside said auditorily-snap-locking recess,

a plurality of threaded L-cross-sectional towers respectively molded to said at least one pin-centering-and-guiding plug,
a plurality of tower leaf springs respectively molded to said threaded L-cross-sectional towers, and
a tower-locking screw screwed between said threaded L-cross-sectional towers
for pushing said threaded L-cross-sectional towers against said umbrella pole to lock said threaded L- cross-sectional towers and said at least one pin-centering-and-guiding tube inside said umbrella pole.

2. The arthritic-aiding pin-guiding auditorily-snap-locking umbrella of claim 1 , wherein said tower leaf springs each have a triangular shape.

3. The arthritic-aiding pin-guiding auditorily-snap-locking umbrella of claim 1 , wherein said threaded L-cross-sectional towers comprise four threaded L-cross sectional
towers.

4. The arthritic-aiding pin-guiding auditorily-snap-locking umbrella of claim 1 , wherein said at least one pin-centering-and-guiding plug comprises two pin-centering-and-guiding plugs.

5. The arthritic-aiding pin-guiding auditorily-snap-locking umbrella of claim 1 , wherein said at least one pin-centering-and-guiding tube comprises two pin-centering-and guiding tubes.

6. The arthritic-aiding pin-guiding auditorily-snap-locking umbrella of claim 1 , wherein said at least one pin opening comprises two pin openings.

7. The arthritic-aiding pin-guiding auditorily-snap-locking umbrella of claim 1 , wherein said cord blocker comprises two L brackets and an hourglass-shaped pulley rotatably riveted to said two L brackets.

8. The arthritic-aiding pin-guiding auditorily-snap-locking umbrella of claim 1 , wherein said cord blocker comprises a U-shaped bracket and two washers molded to said U-shaped bracket.

9. An arthritic-aiding pin-guiding umbrella comprising:
a canopy and pole system comprising:
a canopy, said canopy having a plurality of canopy openings,
a plurality of upper ribs, each of said upper ribs having a rib tip,
a plurality of lower ribs,
a plurality of rib joints respectively attached to said upper ribs and pivotably attached to said lower ribs,
