Abstract
An inflatable umbrella comprising a flexible canopy having at least one enclosed space adapted to be filled with a fluid for inflating the umbrella to an open condition. A self-contained compressible reservoir containing a fluid supply communicates with the enclosed space, and means are provided for compressing said reservoir, which may either be of the manual or automatic type.
Claims25
An umbrella having a shaft and handle portion comprising:
- a flexible canopy having an inflatable enclosed space forming a part of said canopy;
- and having a self-contained compressible fluid reservoir containing a generally permanently closed or sealed fluid supply system communicating with said enclosed space;
- and means for compressing said fluid reservoir, whereby upon compression said fluid is forced into said enclosed space thereby inflating said canopy of said umbrella, and restoration means expanding said fluid reservoir thereby evacuating said enclosed space to deflate said canopy.
An umbrella having a shaft and handle portion comprising:
- a flexible canopy having an inflatable enclosed space forming a part of said canopy;
- a fluid filled compressible, permanently sealed enclosure in communication with said enclosed space;
- resilient transferring means transferring said fluid between said compressible enclosure and said enclosed space when compressed;
- and when released said fluid is transferred back to said compressible enclosure.
An umbrella having a shaft and handle portion comprising:
- a flexible canopy and fluid filled enclosed permanently sealed space having a portion containing restoring means and an inflatable portion, and means for transferring said fluid therebetween with cooperation from said restoring means so that in one condition of said restoring means, the canopy of said umbrella is deflated and in a generally closed condition, and in the alternate condition of said restoring means, said canopy of said umbrella is inflated and in a generally open condition.
An umbrella having a shaft and handle portion comprising:
- a flexible canopy having an inflatable enclosed space forming a part of said canopy;
- a compressible, permanently sealed enclosure communicating with said enclosed space of said flexible canopy;
- a fluid supply in said enclosure and said enclosed space;
- and restoration means urging said compressible enclosure to its maximum volume;
- said fluid supply being of a volume sufficient to provide a fully inflatable enclosed space for opening said flexible canopy to a generally open condition;
- and means squeezing said compressible enclosure so as to force said fluid in said compressible enclosure into said enclosed space.
The umbrella according to claim 25, wherein said other surface comprises a movable slide member mounted on said shaft.
The umbrella according to claim 20, wherein said movable slide member is biased.
An umbrella having a shaft and handle portion comprising:
- a self-contained, generally permanently closed fluid system communicating with enclosed space in a canopy, a variable volume fluid reservoir adapted for fluid transference, means for minimizing the volume of said fluid reservoir, restoring means for expanding the volume of the fluid reservoir, said enclosed space being in communication with said fluid reservoir for bilateral fluid transference between both said enclosed space and said fluid reservoir;
- said enclosed space mutually cooperatively associated with said canopy so that when said fluid is transferred to said enclosed space, said canopy forms a generally rigid extended open configuration, and when said fluid is transferred to said fluid reservoir, said canopy forms a generally collapsed contracted closed configuration.
