(Cl. Z50-108) d @lai-nis.

rlhis invention relates to .a protective device and more particularly to a device :for the protection of individuals from the radiant energy, including the heat and radiationy of an atomic explosion.

One object of the invention is to provide a protective device of the character described which when in use will afford the user complete and adequate protection from the radiant energy ci atomic explosion, which when not in use may be conveniently and readily accessible for ircined use at all times, and which may be instantaneouily prepared for use on the shortest Warning with minimum effort and without danger ci inadvertent or accidental injury to the device.

Other objects of the invention is to provide a?" protective device of the character described which is of simple construction, economical to inanufacture, easy to operate and attractive in appeal ance.

For the purpose of illustration a typical ein-*"I Fig. fl is a top plan view of the embodiment of 'i Fig. l in fully unfolded position ready for use .and with parts broken away;

Fig. 5 is an enlarged section along the line 5 5 of Fig. 4 with parts broken away; and

Fig. 6 is a bottoni plan View oi the protector cover with the blanket omitted.

in the particular embodiment of the invention chosen for the purpose of illustration and with reference to Figs. l and 5 of the drawings the protector comprises a oldable blanket I or mateyrial impervious to the radiant energy of an atomic explosion. While the blanket could be formed from a rubber 01 plastic sheeting initially conm pounded with material impervious to said radiant energy, such as lead or lead oxide in a Well known manner, it is here showny by way of example, as 4comprising outer layers 2 and 3 or" ilexible textile '.iabric and `an intermediate layer d of iiexible sheet metal, as lead foil, preferably having a thickness of theorderof .002 inch. outer and intermediate layers are substantially coextensive and are bonded together preferably throughout their contiguous surfaces -by suitable means as cement.

At its opposite sides 5 and 6 and end -l and preferably along a portion of its opposite end 8 the blanket is formed with a marginal pocket 9 by suitable ,means `as a loop-shaped binding Il), the yinner ends of the binding overlapping and being fast to the outer layers of the blanket, as for example, by stitches l Las `shown Iin Fig.-5. i

The protector also comprises a cover `I 2, here shown by way of example, as comprising crossed strips it and I 4 bonded together'and extending in a direction transverselyand longitudinally of the blanket, respectively, the overlapping portions of the strips vconstituting a substantially rectangular shapedbody portion I5 of the cover, said body portion being bonded to the marginal .portion of the blanket at the end 8 and intermediate the side edges `5 and vil of the blanket by suitable means ras cement, The portions of the strip I3 which extend outwardly from said body portion I5 to the sidesand 6 of the-blanket, respectively, rconstitute a pair of flaps I6 and Il which overlie the blanket when in unfolded position as shownin Fig. 4. The portions of the strip it which extend outwardly from the-,body portion I5 constitute a second pair of flaps `I8 and I9, vthe flap i3 extending loutwardly.beyond the end "8 of the blanket and the flap I 9 overlying the blanket when in unfolded position as shown in Fig. 4.

rI he strips I3 and i4 also comprise material impervious tothe radiant energy of an atomic explosion and are nhere shown, by way ofexample, as comprising outer layers .20 and 2I of flexible textile fabric andinterrnediate'layer 22 of flexible sheet metal, as lead foil, preferably having a thickness of the order of '.0410 inch. Theouter .and intermediate layersofthestrips I3 .and I4 are*substantially,coextensiye.and are bonded together preferably throughout their contiguous surfaces `by suitable means ascement. Preferably alsothe outeredges of thestrips are pro- ,operative in response lto a pullon the cord 35 to puncture one .end of the cartridge to release Vthe .compressed ygas tllereyvithin iA flexible tube v36 communicates atone end with theinteriorvof the 3 receptacle and then enters into the marginal pocket 9l at the end 8 of the blanket and thence extends about the side 6, end 1 and side 5 of the blanket within said marginal pocket. At its opposite end the tube is provided with a threaded gas release plug 31 of the usual commercial type.

The area of the blanket comprises a multiple of the area of the rectangular body portion I of the cover and the blanket is divided into rectangles of the same area as said body portion I5 by spaced longitudinal lines of fold 40 and 4I extending parallel to the side edges of the blanket and by spaced transverse lines of

fold

42, 43, 44 and 45 extending parallel to the ends of the blanket.

In describing the use of the protector and assuming that it is in its fully unfolded position, as shown in Fig. 4, and that all gas within the flexible tube 36 has been released through the plug 31, the plug is closed and the blanket is first folded inwardly and rearwardly from its side edges along the lines of fold 40 and 4| to the position shown in Fig. 3. The blanket is then folded along the lines of

fold

42, 43, M and 45 in successive zigzag folds starting from the end 'I of the blanket so that the entire folded blanket is substantially coextensive with the body portion I5 of the cover, as shown in Fig. 2, and underlies said body portion. The flaps I6 and I1 are then folded rearwardly about the folded blanket and the flaps I8 and I9 are similarly folded rearwardly about the blanket and said folded flaps I6 and I1, with the flap I8 overlapping the flap I8 as shown in Figs. l and 2. The blanket is then releasably secured in said folded position by suitable means as pairs of cooperating snap fasteners 46 and Il provided on flaps I8 and I9. An unexpended gas cartridge is then placed in the receptacle 33.

In this manner the protector while not in use is formed into the compact and neat pack shown in Figs. l and 2 andmay be conveniently kept readily accessible for immediate use on all occasions and may be conveniently carried at the users side while traveling by means of the shoulder strap 48, said shoulder strap being fast at its ends to the outer faces of the flaps I6 and I1, adjacent the body portion I5, by means of rivets 49.

Upon warning of an impending atomic explosion and assuming that the user is wearing the protector at his side, as aforesaid, the user need only pull the flap I8 away from the ap I9 which causes the snap fasteners to release, the flaps I8, IS, I6 and I'I to unfold, and the blanket to fall by force of gravity to the partially unfolded position shown in Fig. 3. The user then jerks the cord 35 of the inflating device 32 thereby to pivot the lever 34 causing the release of gas from the cartridge into the tube 36 to innate the same. Inflation of the tube causes the blanket to unfold to the completely unfolded position shown in Fig. 4. At this time, the user may fall forwardly into a prone position on his stomach drawing the protector over him, as he would a blanket, the

body portion I5 and flaps I6, I'I and I9 of the cover overlying portions of the blanket thereby to afford additional protection to the head, chest and spine of the user.

The protector is thus instantaneously unfolded and prepared for use with minimum effort on the part of the user and without danger of inadvertent or accidental rupturing of the thin sheet metal intermediate layer 4 Which would result 4 from a hasty shaking of the blanket to unfolded position.

While, by Way of illustration, the protector was described above as formed into a releasably secured pack, the invention is applicable to a folded blanket with the pneumatic means described above for unfolding the same.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall Within the scope of the appended claims.
