Claims. (Cl. 13519.5)
This invention relates to umbrellas and more particularly those of self-sustaining material for emergency or temporary use.
The objects of the present invention are to provide an umbrella formed of a sheet of inexpensive form-sustaining material, such as paper treated or calendered to be subst-antially waterproof; to provide an umbrella construction formed of a blank consisting of a sheet of substantially waterproof material cut and scored and folded to form a conical umbrella-like body structure with depending riblike flanges and locks holding the structure in shape and serving as a handle for carrying; to provide such an umbrella structure that is foldable to a reduced size for packing, shipping or storage; to provide such an umbrella structure with tabs and slots for locking the parts in assembled position; and to provide an umbrella that can be manufactured easily and at low cost from inexpensive self form-sustaining material that can be easily stored in a small space and is efficient in use as an emergency um- 'brella.
In accomplishing these and other objects ofthe present invention '1 have provided improved details of structure, the preferred forms of which are illustrated .in the accompanying drawings, wherein:
Fig. 1 is a perspective view of an umbrella embodying the features of the present invention.
Fig. 2 is a plan view of a blank prepared for forming an umbrella.

Fig. 7 is a transverse sectional view through the umbrella on the line 77, Fig. 3.
Fig. 8 is a detail sectional view through the locking tabs and slots in position for holding the rib flanges together.
Fig. 9 is a perspective view of the umbrella looking from underneath same.
Fig. 10 is a perspective viewof the umbrella in partially folded condition.
Fig. 11 is a perspective view of the umbrella in folded condition.
Fig. -12 is an enlarged detail elevation of the locking tab arrangement in the rib flanges.
Referring more in detail to the drawings: v ;1 designates an umbrella which, when erected, includes a body member 2 of substantially conical shape, with depending flanges 3 suitably secured together to form a substantially diametrical rib 4 for aiding in retaining the body member in its conical shape and also for use as a gripping member by which the umbrella is supported over the head of the user. The body member 2 and flanges 3 are preferably formed of a sheet 5 of a suitable semirigid material which is substantially self form-sustaining when shaped and substantially waterproof, as for example, a sheet of paperboard treated or calendered to enhance the ability thereof to shed water or the like.
The sheet of semirigid material is preferably cut to form a blank 6 as illustrated in Fig. 2. The blank includes spaced body sections 7 and 8, each of which has circular peripheral edges 9 of a length forming one-half of the circle at the periphery or base of the conical body member 2. The bodysections 7 and 3 are each defined by the circular edges 9 and score lines 10 and 11, which intersect .as at 12 whereby the body sections 7 and 8 each forms one-half of the conical body member 2 and the point of intersection 12 of the score lines 10 and 11 is at the apex of the conical body member 2.
Each body section 7 and 8 is preferably provided with radial score lines 13 and 14 to divide the respective sections into three equal portions whereby the structure can be folded into a small package, however, if desired the score lines 13 and 14 may be omitted and then when folded the structure would be relatively fiat and of a size substantially equal to one of the sections 7 or 8. The score lines 1% of the sections 7 and 8 are spaced apart as at 15 adjacent the periphery of the blank and diverge to the points 12, as illustrated in Fig. 2. The portion of the blank between the score lines 10 is substantially equally divided by a score line 16 which cooperates with the score lines It to define connected flanges 17 and 18 connected at the score lines 19 with the umbrella sections 7 and 8 respectively. Flanges 19 and 20 are connected to the umbrella sections 7 and 8 respectively at the score lines 11 thereof. The spacings between the score lines 11 and the edges 21 of the flanges 19 and 29 are substantially identical with the spacing and angular arrangement between the score lines It and the score line 16. The edges 21 of the flanges 19 and 29, as shown in the blank in Fig. 2, converge to a point 22, and cuts 23 and 24 extend from the point 22 to the points 12 to define the inner ends of the flanges 7 and 19 and 18 and 2t) respectively.
The flanges 17 and 18 are preferably provided with substantially U-shaped cuts substantially midway between the ends of said flanges, and score lines extend between the legs of the U-shaped cuts to form tabs 25 of suitable size that when the tabs are hinged from the flanges handholds 26 are provided therein. The tabs 25 and the handholds cooperate to form locking members as later described. The flanges 17 and 18 are provided with pairs of U-shaped cuts 27 adjacent the ends of the flanges, as defined by the cuts 23 and 24, and the flanges 19 and 20 are each provided with spaced apertures 28 and 28' which cooperate with tabs 29 formed by the U-shaped cuts 27 to provide locking structures as later described. The apertures 28 are of such size that the tabs 29 will pass therethrough and the apertures 23' are smaller in size.
The blank 6 is folded on the score line 16 whereby the flanges 17 and 18 are moved into face to face contact and said flanges are suitably secured together by glue or other suitable fastening devices, for example staples 30, arranged adjacent the score lines 10. The flanges 19 and 20 are then brought together into face to face contact whereby they extend from the score lines 11 in the same direction as the flanges 17 and 18 extend from the score lines 10, with the inner portions of the flanges 19 and 20 overlapping the sides of the flanges 17 and 18. Then the flanges 19 and 20 are suitably secured together by staples 31, or other suitable fastening devices arranged adjacent the score lines 11 and the edges 21, the fastening of the flanges 19 and 20 extending from the periphery of the umbrella sections toward the apex thereof and terminating in spaced relation to the apex a distance slightly greater than the length of the edges formed by the cuts 23 and 24. Then if the score lines 13 and 14 are omitted the body sections 7 and 8 may be folded on the score lines 10 and 11 to provide a flat structure substantially the shape of either of the sections 7 or 8 and may be stored until it is desired to use the umbrella.
With the score lines 13 and 14 the body sections 7 and 8 are folded on the score lines 13 whereby the portion between the score lines 10 and 13 are swung inwardly to lie under the portions between the score lines 13 and 14 of the respective sections, as illustrated in Fig. 10, and during such folding the rib portion defined by the flanges 17 and 18 moves between the unfastened inner portion of the flanges 19 and 20 to a position illustrated in Figs. 5, l0 and 11, whereby the folded structure is flat and substantially twothirds of the area of a body section 7 or 8.
When it is desired to use the umbrella structure, the body member is grasped to swing the body sections on their respective score lines to move the body to a substantially conical form and the tabs 29 aligned with the apertures 27. Then a finger is inserted in the apertures 28' to press the tabs 29 through the apertures 28, as illustrated in Fig. 8, tain the body 2 in substantially a conical form. The tabs are then pressed to fold same outwardly on the score lines to provide the handholds for grasping the rib forming flanges 17 and 18 whereby the umbrella structure may be supported over the head of the user.
After use, the tabs 29 may be pressed back through the apertures 28 into coplanar arrangement with the flanges 19 and 20 and the umbrella structure again folded for storage until it is desired to again use same.
