Patented Apr. 27, 1943 CONVERTIBLE TEXTILE ARTICLE Ernst Harald Wallin, Arvika, Sweden Application October 18,1939, Serial No. 300,006 In Sweden March 23, 1938 1 Claim.

The present invention relates to textile articles, such as tent portions, sleeping bags, coats and the like which can be converted into knapsacks.

One object of the invention is to produce an article of the type referred to which is flexible in all its portions, but can be attached to a supporting frame in such a manner, that, without any additional stiffening elements, a substantially stiff back portion for a knapsack is formed.

Another object of the invention is to construct an article of flexible material, which, when mounted on a carrier frame of simple construction, can be converted into a knapsack the back portion of which is effectively prevented from crumpling or collapsing without the use of any stiffening means which are diificult to attach and increase the weight of the article.

These and other objects, which will appear more clearly as the specification proceeds, are accomplished by the arrangement and combination of elements set forth in the following detailed description, defined in the appended claim, and illustratively exemplified in the accompanying drawing in which:

Fig. 1 is a plan view of a convertible tent portion according to the invention in combination with a suitable hip and shoulder harness.

Fig. 2 is a plan view of a sleeping bag according to the invention, and

Fig. 3 is a partial plan view of the same bag, some parts being shown in section.

Referring now to the drawing, and first to Fig. 1, I denotes a tent portion having secured thereto two elongated sleeves 2 slightly inclined towards one another. A carrier frame including hip harness 5 having mounted thereon two elon gated rails 3, 4, is secured to the tent portion by means of the rails 3, 4 inserted into the sleeves 2. Two straps ll, [2 extending through slots 2a in the side walls of the sleeves 2 (see Fig. 3) serve to hold together the packing after the tent portion has been folded. The sleeves 2 have a length only slightly less than that of the rails 3, 4 so as to prevent the converted tent portion from gliddown along the rails when it is carried on the back of a person. 7

In Fig. 2, I denotes a sleeping.v bag provided with sleeves 2. The sleeping-bag is also provided with pockets 8, 9, and by folding the bag in a suitable way it is, thus, possible during transport to have an easy access to the articles in the said pockets.

Fig. 3 shows the top walls of sleeves 2 partly broken away, the side walls with the slots 2a being shown in section.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

For use with a carrier frame adapted to be attached to the back of a person and including two substantially rigid elements extending in a substantially vertical direction and being spaced from each other, shoulder straps to which the upper ends of said elements are connected and a hip harness to which the lower ends of said rigid elements are. secured, an article made of flexible material and adapted to be supported on said carrier frame, said article including a flexible back portion which is to lie adjacent the back of said person when said article is supported on said frame, and two elongated sleeves of flexible material secured to the outer surface of said back portion in substantially the same relationship with respect to each other as said rigid elements of said frame to telescopically receive said elements, said sleeves having a length slightly less than that of said elements and being provided with aligned slots to receive a holder strap.

ERNST HARALD WALLIN.
