4 Claims.

This invention relates to an inflatable and pliable umbrella-like head covering which may be kept in compact rolled up condition, but which may be inflated by air blown thereinto and in such a way that the head cover will be enlarged in area when in an inflated condition and adapted to be held by the user at its central portion and serve as an umbrella.

An object of this invention is to provide a collapsible and extensible umbrella-like head covering, comprising an inflatable disk-like body having diametrically disposed ribs and a central air chamber communicating with the ribs and to mount an air valve in one of the ribs so as to make it possible to inflate the central chamber and the ribs simultaneously when air is blown through the valve into one of the ribs.

Another object of this invention is to provide a modified collapsible and extensible umbrellalike head covering, comprising inflatable disklike body having hollow diametrically disposed ribs communicating with a circumscribing circular rib so that the head covering substantially simulates an umbrella body having a true circular outer edge.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts ti roughout the several views, in which:

Figure l is a top device.

Figure 2 is a cross-sectional view taken on line 2-2 in Figure 1.

Figure 3 is a central cross-sectional view of an air valve assembly, on a greatly enlarged scale.

Figure 4 is a top plan view of a modified form of the device.

Figure 5 is a side elevation of the modified form shown in Figure 4, the device being partly broken away to show the interior thereof.

In the illus rated embodiment of the invention, the numeral it indicates a collapsible and extensible umbrella-like head covering, comprising an inflatable disk-like body l i having straight tubular and radially disposed ribs or passageways 52.

At the central portion of the body H is an air chamber l3 communicating with the passageways 52.

plan view of one form of the The body ii is preferably made of two 58 plastic disks it, it which are positioned in superposed relation and joined by the application of heat and pressure to major portions of the disks. It is to be noted that the disks i l, it are hermetically joined completely around their peripheral edges to form a jointed flange l5 and that the outer end of each passageway terminates at the said jointed circular flange it.

As shown in Figure 2, the inner ends of the passageways i2 merge with the air chamber i3 whereby the air in the chamber 53 is in communication with the passageways it. A suitable air valve 16 is inserted into and fixed in one of the passageways 52 which is made to extend to the outer periphery of the body 1 l and this makes it possible for air to be blown there'through for inflating the air chamber [3 and passageways 2. The air imparts a degree of rigidity to the passageways and to the head covering in service position so that the head covering substantially simulates an umbrella body.

As shown in Figure 2 there is provided a circular connecting m mber 18 having shoulders 59 and upper and lower extensions til. The upper shoulder 59 is in contact with an apertured central portion or annular flange Ell of the plastic disk 1 5 through which passes the upper extension 23. A washer Z2 is placed over the upper extension 26. The free end portion of the extension as is riveted over the washer 22 and this clamps the plastic disk 54 in airtight relation on the connecting member l8.

The lower shoulder i9 is in contact with an apertured central portion or annular flange 24 of the plastic disk M through which passes the lower extension it. A washer 22 is placed over the lower extension 26. The free end portion of the extension is is riveted over the washer 22 and this clamps the plastic disk it in air tight relation on the connecting member it.

The connecting member :8 connects the upper and lower disks 3 4 i l of the plastic covering material and keeps them in desired spaced-apart relation. A rod 23 having a threaded end 25 is threaded into a threaded lower portion of the connecting member l8 and provides a handle by which the head covering it is carried when the ribs 52 and the air chamber 33 are inflated.

As shown in Figures 1 and 2, it will be seen that between the rib-shaped passageways it are sectoral portions 2? which are inherently fiat due to the upper and lower layers being cemented together in abutting relation at said sectoral portions, and that solely upon inflation of the ribbed passageways 12, the sectoral portions ll assume a planar form. This construction shows the central portions of the ribs l2 and the sectoral portions H as lying in aiinement in the same plane and this alinmnent permits the entire body H to be rollaole into compact package form when the ribs i2 are deflated.

As shown in Figures 1 and. 2, it will be seen that the area of the hollow inflatable ribbed passageways constitutes a small percentage of the area of the non-inflatable planar sectors. It will also be seen that the ribbed passageways iii are straight, tubular, and extend equidistantly above and below the planar sectors ll. Particularly, it is to be noted that the adjacent ribbed passageways l2 are in far spaced-apart relation from each other, being positioned forty-five degrees apart.

Figure 3 is a central cross-sectional view on an enlarged scale of the air valve l6 shown in Figures 1 and 2 for blowing air into the ribs i2 and the air chamber IS.

The air valve assembly It comprises a valve body 27 having an inlet passage 23, an outlet chamber 28 and a valve seat 3%. A valve having a stem 32 is slidably mounted in the valve passage 28 and has a valve head 34 pressed against the valve seat 39 by a coil spring 35. The spring reacts against a disk 36 suitably fixed at the outer end of the chamber 29. The disk 36 has outlet passages 3'! for air passing through the valve it.

The valve 33 has grooves 45! on its outer peripheral surface which permit air blown into the inlet passage 28 to pass through the valve when the air pressure against the valve head 34 is greater than that exerted by the spring 35.

Figures 4 and show a modified collapsible and extensible umbrella-like head covering 44, comprising an inflatable disk-like body 55 ne ing hollow diametrically disposed ribs :3 communicating with a circumscribing circular rib 51.

At the central portion of the body 65 is an air chamber is communicating with the ribs it. The body 45 is preferably made of two plastic disks 5! 53 which are positioned in superposed relation and joined by the application of heat and pressure to major portions of the disks. It is to be noted that the disks 5t, 5!) are hermetically joined completely around their peripheral edges to form a jointed flange 5!.

As shown in Figure 5, the inner ends of the ribs 46 merge with the air chamber 68 whereby air in the chamber MB is in communication with the ribs 46. A suitable air valve [6 is inserted into and fixed in the circular rib 47 which is i made to extend to the outer periphery of the body 65 and this makes it possible for air to be blown through the valve for inflating the air chamber 48 and the ribs 48. The air imparts a degree of rigidity to the ribs 46, i? and to the head covering in service position so that the head covering substantially simulates an umbrella body having a true circular outer edge.

It is also to be noted that the upper surface 59 of the head covering shown in Figure 5 tapers downwardly to simulate the appearance oi an umbrella.

Figure 5 shows an elongated two member container type handle 55 which comprises a tubular lower member 56 having a closed lower end 5'! and an open upper end 56. The upper end is internally threaded. The handle 55 includes an upper member 59 made of a rod 60 having a thread SI at one end which may be screwed into a threaded member 52 suitably fixed. to the cen tral lower portion of the plastic disk At the opposite end, the rod fill terminates in an enlarged externally threaded collar 53 of a size adapted to fit into the threaded upper portion 58 of the tubular lower handle member 56 to form the elongated handle 55.

lVhen the handle members 56 and 59 are threaded in unitary relation, the user grasps the tubular lower member 55. When not in use, the

tubular lower handle member is disconnected from the upper handle member 59. The handle member 59 is removed from the disk-like body The head covering 54 is deflated and rolled around the rod 60 of the upper handle member 59 so as to form a compact tightly rolled cylindrical unit of a size to permit entry into the tubular lower handle member 56.

It is to be noted that when the rolled up head covering is placed inside the tubular lower member 56, the threaded collar 63 is outside the lower member and is threaded into the thread in the lower handle member. The head covering is then concealed inside the lower handle member or container. When not in use, the user only carries around a tubular container of package form and of small size adapted to be placed in side a hand bag or pocket.

It is also to be noted that the valve mechanism may be taken as representing any suitable means for performing the same function.

It is also to be noted that the gist of the invention is to provide an inflatable linear portion or portions on the hollow body which when infiated function as ribs, the same as in an umbrella.

When it is desired to deflate the head covering, the user presses the valve stem 32 inwardly of the valve body 2! and allows the air in the head covering to escape. For this purpose, the valve stem 32 may be made long enough to extend outwardly beyond the valve body.

For low cost production, the valve 33 may be simply in the form of a hinged disk.

In accordance with the patent statutes we have described and illustrated the preferred embodiments of our invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.
