invention relates to an umbrella and more particularly to an mnbrella which is intended for use in an emergency and capable of giving a substantial amount of protectionfor a reasonable amount of time against rain, snow storm and sunshine.

'It'is' the object of this invention to provide an umbrella of this character which can be manufactured at relatively low cost so that'the same can be discarded after being used comparatively few times withoutentailing appreciable; loss, and which can be readily disassembled and compactly folded into the form ofa' relatively sniall package that can be easily transported or carried in the pocket of a garmentor the like and also unfolded and assembled with ease and facility'for practical use.

In the following description similar nurnerals indicate like parts in the several views of the drawings:

In gfenerai this umbrella comprises a canopy capab e of being folded into a compact bundle and also unfolded for use. a plurality of ribs for supporting the canopy. and a handle whereby the canopy and ribs are supported by hand when in use and which also serves as a case in which the canopy andribs are enclosed in a folded condition whenthe umbrella is not in use.

The canopy is preferably constructed of a circular sheet It] of thin "material such as cloth, paper or the like of sumcient strength to withstand destruction by ordinary rain, wind or the like and capable of being spread or unfolded into the form of a plurality of sectors llarranged in an annular row around the center of the umbrella for use as a covering, as shown in Figs. 1 and 2 and also capable of being folded to form a plurality of pleats or loopsl2 which are arranged side by side to form a compact group, when not in use; as shown in Figs. 6, '7 and 8. Each of these loops is form-ed from one of these sectors by folding the latter on a radial line midway between itsopposite radial sides so that the pleator loop hangs downwardly, as shown in Figs. 7 and 8. I

. In order to permit the sectors of the canopy sheet to be thus folded individually and collec'ted as a group in which the several loops are arranged side by side; the circular canopy is provided with a radial slit extending from its axis to its periphery and thereby form two radial edges on the canopy-which for convenience will bereferred to as the inner and outer radial joint edges l3, l4 of the canopy which are adapted to be joined when unfolding the canopy into circular form for useandseparated when the canopy is folded'for storage or bundling.

'I-hecanopy is supported by a plurality of ribs #5 of thin cardboard or the like, preferably six in number which are arranged equidistant around the underside of the canopy and each connected at its upper edge to the underside of the canopy-by an adhesive or other suitable means. The several ribs are so arranged that the same are in line with the radial sides of the several canopy sectors. All of the ribs, ex ceptone, are arranged intermediate of the radial joint edges of the canopy, and this one is additionally connected with-the inner radial joint edge t3 of the canopy by providing this edge of the canopy with a vertical radial flap or flange H which projects downwardly from the canopy into engagement with the front side of the respective end rib #5 as shown in Fig. 5, and is secured thereto by an adhesive or otherwise. At its outer radial joint edge [A the canopy is provided on its underside with a radial coupling strip 16, as shown in Figs.- 1, 2, 3,- 5 and 8 which is secured thereto by cement or otherwise.

T e canopy is held in its spread out or unfolded position by lapping the coupling strip H at the outer radial joint edge [4 of the canopy over inner radial joint edge It and connecting this coupling strip with the adjacent endmost rib l 5 with this coupling strip and the respective radial edge of the canopy by one or more fastening clips each of which has a body It secured by a rivet E9 to the outer side of the respective rib and provided with a tongue 20 which projects upwardly through a slit 2] in the coupling strip and the canopy and is bent downwardly against the upper side of the canopy, as best shown in Fig. 5.

When it is desired to fold the canopy and ribs so the sectors form loops orpleats which are arranged parallel with each other and the ribs are also arranged parallel adjacent to the border lines between adjacent canopy loops, this can. be done by first straightening the tongue 20 of each clip and withdrawing the same from the respective slit 2! in the coupling strip.

Although the ribs may be secured individually to the underside of the canopy it is preferable to form these ribs in pairs and connect the inner ends of the ribs of each pair by a thin web 22 so as to form a hinge whereby the members of each pair of ribs may turn laterally relatively to one another for the purpose of spreading the ribs out into circumferentially spaced relation, as shown in Figs. 2 and 3,0r folded into parallel relation, as shown in Fig. 6. 7

In order to permit the ribs to be thus folded and unfolded relative to each other and reliably retain them in their proper position relative to one another and also relative to the axis of the canopy, one of the ribs of each pair is connected at its inner end by a hinge with the inner end of a rib of an adjacent pair of ribs, as shown at 23 in Figs. 1, 2, 3 and 4, these hinges preferably consisting of flexible material such as paper,

cloth and the like which is cemented to the ribs. Supporting means are provided for conveniently supporting the canopy and associated parts while the latter are unfolded for use, these supporting means being preferably constructed as follows! The numeral 24 represents a vertical supporting shank projecting downwardly from the inner end of each rib and preferably formed integrally therewith. When the canopy and ribs are unfolded into an operative positio the several shanks of the ribs together form a cluster in which the shanks radiate from the center of the canopy and in effect produce a downwardly projectinghub. This hub is slipped downwardly into the upper end of a tube 25 of cardboard or the like, so that the latter forms a handle whereby the umbrella may be conveniently carried in the hand when the same is used for sheltering from the weather. g

If desired the neck of the umbrella may be fitted sufiiciently tight in the tubular handle that these parts will be held together by friction but it is preferable to employ additional fastening means which positively interlock the same. This is accomplished in accordance with the present invention by means of a coupling or fastening pin 2'6, which is adapted to pass through openings 21 on opposite sides of the upper part of the tubular handle and also through openings 28 and 9 in one of the webs 22 and one of the hinge strips 23 and through notches 39 in the inner end of some of, the ribs as shown in Figs, 1, 2, 3 and 4, and thereby securely fastening the hub and tube together and preventing separation of the same while the umbrella is in use.

The tubular handle is also preferably utilized as a case or container in which the canopy and ribs and parts connected therewith may be conveniently stored ready for use. For this purpose the canopy and ribs and the parts connected therewith are first rolled together about the axis of the umbrella into a compact package and then slipped into the tubular handle from the lower to ward the upper end of the same, as shown in Fig. 9. In order to avoid the necessity of making the tubular handle unduly large in diameter the same is only made large enough to receive the or string 32 with the upper part of the tubular handle and adapted to be inserted within this part of the handle, as shown in Fig. 9.

When'the several parts of the umbrella are thus assembled the same can be easily stowed with other equipment in a traveling bag or in a pocket of clothing andwhen required for use can be quickly and easily unpacked and erected, thereby rendering the same particularly useful i case of emergency such as unexpected rain or storm such as may be experienced at picnics, football games, racing meets and the like.

If desired the several ribs may be pivotally connected with each other at their inner ends so as to permit of folding and: unfolding them circumferentially relatively to each other by the means which are shown in Fig. 10 and which consists of a hinge strip of flexible or pliable material having a body portion 33 cemented to inner edges of the several ribs and provided at its opposite ends with tabs 34 which are similarly fastened to the opposing longitudinal sides of the endmost ribs of the group. a
