Abstract
Abstract An umbrella adapted to be illuminated selectively when in its open position. A hollow tubular shaft supports the umbrella hood by means of a hub slidably mounted on the shaft. The hub carries an electrical conductor cooperable with electrical contacts in the bulb circuit and with the switch preventing illumination of the bulb unless the hood is open and then only by means of the switch.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
An illuminatable umbrella comprising: a hollow tubular shaft; a hub slidably mounted on said shaft and having electrical conductor means on an inner portion thereof, said hub pivotably carrying a plurality of rib elements which support an umbrella hood; means for mounting an electric bulb at one end of said shaft; at least one battery mounted within said hollow shaft; a manually operable electric switch carried by said shaft; electrical conductor elements positioned within said shaft connecting said switch, batteries and bulb in a series circuit; and a pair of electrical contacts interposed in said series circuit adjacent the external surface of said shaft cooperable with said electrical conductor means on said hub, whereby upon engagement of said contacts by said electrical conductor means said switch can be manipulated to selectively energize said bulb.
Claim 2
Dependent Claim
134 words
An illuminatable umbrella comprising: a hollow tubular shaft; a hub slidably mounted on said shaft and having electrical conductor means on an inner portion thereof, said hub pivotably carrying a plurality of rib elements which support an umbrella hood; means for mounting an electric bulb at one end of said shaft; at least one battery mounted within said hollow shaft; a manually operable electric switch carried by said shaft; electrical conductor elements positioned within said shaft connecting said switch, batteries and bulb in a series circuit; and a pair of electrical contacts interposed in said series circuit adjacent the external surface of said shaft cooperable with said electrical conductor means on said hub, whereby upon engagement of said contacts by said electrical conductor means said switch can be manipulated to selectively energize said bulb.
Claim 3
Dependent Claim
54 words
An illuminatable umbrella according to claim 1, wherein a resilient latch element is mounted on said hollow shaft normally biased outwardly into the path of movement of said hub to thereby maintain the electrical conductor means of said hub in engagement with said electrical contacts when the umbrella hood is in its open condition.
Claim 4
Dependent Claim
28 words
An illuminatable umbrella according to claim 1, wherein said pair of electrical contacts comprise ball contacts interposed between said hub and said shaft and sealingly engaging said shaft.
Claim 5
Dependent Claim
47 words
An illuminatable umbrella according to claim 1, wherein said electric switch is mounted externally of said hollow shaft and is adapted to selectively close the series circuit connecting said batteries, bulb and electrical contacts when said hood is in its open position to thereby energize said bulb.
