UMBREL A.

Application fil ed May 22,

The invention relates to temporary or emergency umbrellas, and especially to those having a body structure formed from self form-sustaining material, the object being to provide an umbrella of the type referred to with flap-like supporting means connected to. the umbrella to hang down freely in umbrella-supporting position and to be swung against the side when not "in use. I

The umbrella according to the invention comprises a conical, umbrella-like body structure formed from self form-sustaining material, and flap-like supporting means connected at one end to the underside thereof at a point removed from its apex. The-body structure is preferably formed from a single sheet of suitable material, by forming a slit inwardly from the edge and overlapping the material adjacent thereto to form a. conical structure, the overlapping edges being connected in any suitable manner. In the preferred form the supporting means comprise strips of semi-rigid material connected tothe under side of the structure at a point intermediate the edge and the apex, the strips being hinged at their inner connected ends so that they may hang freely in umbrella supporting position, or may be swung against the side when not in use to facilitate packing, sliippage, or storage. Preferably two diametrically opposed strips areused.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which Fig. 1 is a plan view of a sheet of material prepared for forming an umbrella; Fig. 2 an elevation of an umbrella made from the sheet shown in Fig. 1; Fig. 3 a detached supporting member shown to enlarged scale; and Fig. 4 anenlarged sectional View showing one manner of connecting a supporting member.

Having reference to the drawings, the umbrella comprises a body portion 1, Fig. 2, and depending supporting members 2 connected thereto. The body is formed from a sheet 3 of a suitable semi-rigid material possessing sufficient rigidity to make it self form-sustaining when shaped, and sufficiently waterproofed, such as parafiined or calendered cardboard. Although the structure may be shaped in various ways, it is preferred to do this byforming a slit 4, Fig. 1, in a circular sheet 3, extendingfrom the edge substantially to the center, and lapping a portion A over the other edge portion B to form these members may vary, as may the manner of connecting them,

a conical umbrella-like structure of the de sired proportions, such as that shown in Fig. 2. The overlapped material is connected together inany appropriate manner, as by stitching, gluing, and the like, and the struc ture thus formed requires no auxiliary reinforcement to maintain it in shape. V

The supporting means used is preferably formed from" strips of semi-rigid material, such as that used in'making the body structure. As shown in Fig. 2, it' is preferred to use two such members each connected at one end to the body structure at a point removed from its apex. The form and dimensions of provided adequate strength is secured, the preferred manner of connecting them being shown in Figs. 2 and 4. One'end of each strip 2 is bent to provide a foot or flange 5, which is glued or stitched to the underside of the body 1 at a pointintermediate theedge and the apex, and strips of adhesive material 6, such 'as gummed paper, are placed over the flange 5 andin the angle on the opposite side to further strengthen the joint. 5

By this construction the supporting members hang freely in umbrella-supporting position in a manner similar to that of theusual umbrellas may be readily stacked for storage or shipment. The hinge-'actionmay, if de sired be furthered. by providing a line of weakness 7 in the-strip. Where two strips are used,they are preferably disposed diametrically opposite each-other at equal distances from the apex of body 1, the distance between them being such that when held over the head, the strips depend on each side thereof. By this construction, .the umbrella may be held in proper position by grasping one strip in each hand, or by grasping both in one I hand, in which case the strips will converge,

and can beheld readily for adequate protec- 100 tion. The umbrellas are especially suitable for distribution to personscongregated outdoors, as at fairs, athletic events, or other gatherings, and advertising matter may be printed on them so that they provide an ex- 1 cellent and very'inexpensive publicity medium for free distribution, or for sale at a smallsum. v

According to the provisions of the patent statutes, I have explained theprinciple and 1,10

operation of myinvention, and have illustratedand described what Inow consider to represent its best embodiment. However, I desire to have it understood that, within the scope of. the appendedclaims, the invention may be practicedotherwise than as specifically illustrated and described.

2. An emergency umbrella fconsisting of a single sheet of semi-rigid material formed into a self form-sustaining umbrellaslike structure, and a pair of flapfli'ke' supporting members connected at their inner ends to the underside of said structure at points intermediate its edge and apex, said members hangi g r e yfro the r poin s not c n tion when in umbrella-supporting position and adapted to swing against the body of the umbrella when not in use.
