Umbrella having structural rib configured to receive electrical components and associated wiring
An umbrella has a first support member, a plurality of ribs supported by the first support member, and a canopy supported by the plurality of ribs. At least one of the plurality of ribs has, in cross section, a bottom wall, first and second upstanding side walls extending upward from the bottom wall, and a web extending between the first and second side walls at a location intermediate the bottom wall and the upper side wall ends. The web and upper portions of the first and second side walls form a channel. A first hole extends through the web, and a second hole extends through the bottom wall generally in coaxial alignment with the first hole. In a disclosed embodiment, a light bulb is disposed within either or both of the first and second holes, and an insulated electrical conductor runs along the length of the rib within the channel to connect the light bulb to a source of electrical power.
1. An umbrella, comprising:
a first support member;
a plurality of elongated ribs supported by said first support member; and
a canopy supported by said plurality of elongated ribs,
wherein at least one of said plurality of elongated ribs has, in cross section,
a bottom wall;
a first upstanding side wall extending upward from said bottom wall to an upper side wall end;
a second upstanding side wall extending upward from said bottom wall to the upper side wall end;
a web extending between said first and second side walls at a location intermediate said bottom wall and said upper side wall ends, said web and portions of said first and second side walls above said web forming a channel, and said web and portions of said first and second side walls below said web forming a cavity;
a first hole extending through said web; and
a second hole extending through said bottom wall generally in coaxial alignment with said first hole;
a bulb extending from below said second hole, up through said cavity, to said first hole, whereby the bulb may be readily accessed from said channel for insertion into or removal from said cavity, and
wherein an electrical conductor runs from the bulb along said channel, to a source at electrical power.
2. The umbrella of claim 1 wherein said source of electrical power comprises a battery charged by a solar panel.
3. The umbrella of claim 1 , wherein the upper side wall end of the first and second upstanding side walls comprise a rounded rim portion configured to support the canopy.
4. The umbrella of claim 1 , wherein the bulb is selected from the group consisting of a light emitting diode, an incandescent bulb, and a fluorescent lamp.
5. The umbrella of claim 1 wherein the bulb comprises a light emitting portion and a separable housing portion.
