ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a disposable umbrella and in particular to a disposable umbrella with chemical light.
2. Description of the Prior Art
Conventional umbrellas require the mechanical assembly of many parts made of a wide variety of materials. Such multiplicity of parts and materials makes the umbrella expensive. A desired alternative is a disposable umbrella of simple design and inexpensive manufacture. U.S. Pat. No. 4,821,756 discloses a disposable umbrella with supporting struts joined by living hinges which when folded is contained with a protective tube. What is needed beyond the prior art is an even simpler design. A second need beyond the prior art is for an umbrella with an inexpensive means of illumination.
SUMMARY OF THE INVENTION
The present invention meets the needs and solves the problems identified above by providing an umbrella having a molded handle, a translucent telescopic center shaft, and a plastic dome. When opened, the umbrella's dome is supported by a series of flexible plastic spokes with living hinges. The plastic dome is attached to the spokes by heat welding to supporting tabs. The section of the telescoping shaft nearest the handle has a cut out section for insertion of a “lightstick” so that the user can activate the chemically based glowstick and insert it into the cut out section and also remove and replace it as needed.
