Inflatable umbrella
| Details |
Inventors: Wallace, William E.;
Assignee:
Primary Examiner: Schroeder; Werner H.
Assistant Examiner: Berman; Conrad L.
Attorney, Agent or Firm: Stein, Orman, and Pettis
A pocket-sized inflatable umbrella of the type primarily intended for disposal after a single use including a thin flexible plastic sheet having air passages formed therein, wherein the sheet is dimensioned and configured to substantially define a hemisphere surrounding the head and/or shoulders of the user when inflated. The sheet is fixedly attached to a telescoping sleeve, both of which fit into a housing of a suitable size and configuration for carrying in a pocket or purse. When the sleeve is extended from the housing, the plastic sheet is inflated, and the housing serves as a handle for the umbrella. |

DETAILED DESCRIPTION The present invention relates to an umbrella structure designed and constructed to protect the user from inclement weather.
To enhance the protection capabilities of the umbrella, its canopy is inflatable to a predetermined configuration, and the device is provided with specific means for accomplishing this inflation as well as retaining the canopy in an inflated configuration.
The umbrella is pocket-sized and, while it may be re-used, it is primarily intended for disposal after a single use.
Accordingly, the inflatable umbrella of the present invention comprises a flexible sheet which serves as a canopy or protector means.
The protector means is formed from two sheets of the flexible material, such as plastic, and the two sheets are sealed one to another at predetermined points in such a fashion as to define air passages therebetween, whereby the protector may be inflated.
It is preferred that this sealing and other forming of the protector be accomplished to define a predetermined configuration thereof.
Such predetermined configuration is preferably disclosed as a dome-like shape to accomplish maximum protection to the user.
It should be noted that other shapes or configurations could be utilized dependent upon the particular application.
As will be explained in greater detail hereinafter, the protector means or canopy is folded upon itself around a sleeve, and the protector and sleeve are disposed within a housing to provide an umbrella which may be carried in the user's pocket.
Inasmuch as it is well known that items of identical substance tend to cohese when they are placed next to each other, one embodiment of the present invention may comprise the application of a cohesion inhibitor to the protector means to aid in inflating and opening the device.
If such is desired, the cohesion inhibitor of my presently co-pending application Ser.
No.
536,550, filed Dec.
26, 1974, may be utilized.
The central, or hub, portion of the protector is fixedly attached in fluid communicating relation to a sleeve, which sleeve serves as a support element for the umbrella in use
