POSTER.

Application filed July 28,

This invention relatesto posters of the socalled flexible type and the objects of the invention are to provide simple and inexpensive means for supporting these large flexible posters, which can be easily. set up or taken down, which can be folded into small space and which will be generally practical and desirable.

The objects as set forth and others as Wlll appear later, are attained in this invention by certain novel features of construction, combination and relations of parts as hereinafter described and claimed.

The drawing accompanying and forming part of this specification illustrates a practical commercial embodiment of the invention, but it should be understood that the structure may be modified without departure from the true spirit and broad scope of the invention.

Fig. 1 is a perspective rear View of the poster; Fig. 2 is an enlarged sectional view of the double tubular spring connection between the two rods of the supporting structure.

The body of the poster is illustrated as a sheet of flexible material provided with edge strips 5 and 6.

The upper edge strip is shown ashaving a downwardly and rearwardly faced socket 7 and the lower edge strip is shownas havin g a rearwardly and downwardly faced socket 8.

Engaged with the upper socket '7 is a supporting rod shown as made up of an upper section 9 telescopically fitted at 10 into the upper end of a rod section 11.

A rod 12 forming a rearwardly projecting prop is shown entered in the socket 8' in the lower edge strip.

The rearward end of the prop rod 12 is shown as shouldered to presentthe end sections 13, 1 1 of different diameters and similarly the lower end of the support rod 11 is shown as shouldered to present the end sections 15, 16 of different diameters, but equal k to the diameters 13, 14 respectively.

Engaged over the smaller end sections 13, 15 of the two rod members is a tubular spring connector or coupling shown as a closely coiled wire spring 17 and engaged over the larger portions 14, 16 is a larger sized tubu- 1928. Serial No. 295,518.

lar spring coupling in the form of a heavier wire coil spring 18.

The sectional View Fig. 2 shows how the outer coil spring encloses and braces the inpound spring structure is sufficiently flexible to enable the rods being bent toward each other enough to engage the ends of the same in the sockets provided in the edge strips. This structure also is lighter, more resilient and better suited to supporting a large poster than a single coil spring made of much heavier wire. This is in tact due largely to the bracing effect of one coil spring within the other, the two bending on different curves as shown in Fig. 2, so that they touch at different points and one helps to support the other.

Upon disconnecting the two rod sections 9 and 11, the parts may be rolled with the poster into relatively small space, and if desired, the rod members 11 and 12 may be disconnected by pulling one or the other out of the connecting springs. The parts may just as easily be put together when the poster is set up.

What is claimed is:

1. In combination with a large flexible poster having edge strips, rod-like members engaged with said edge strips and projecting on convergent angles from the rear of the poster, a spring connecting the convergent ends of said rod-like members and a coiled spring surrounding said first spring as a casing and also connecting the convergent ends of said rod-like members.

2. In combination with a. large flexible poster having edge strips, rod-like members engaged with said edge strips and projecting rearwardly on convergent angles, a silient spring casing connecting the convergent ends of the rod-like mon'ibers and a spring connection between the convergent ends of said members within said spring casing and supported thereby.

3. In combination with a large flexible poster having edge strips, rod-like members engaged with said edge strips and projecting rearwardly on convergent angles, a resilient spring casing connecting the convergent ends of the rod-like members, a spring connection between the convergent ends of said members within said spring casing and supported thereby, one of said rod-like mom- 0 rs consisting of telescopically joined detachable parts.

4:, In combination with a large flexible poster having edge strips, rod-like members engaged with said edge strips and projecting rearwardly on convergent angles, a resilient spring casing coimecting the convergent ends of the rod-like members, a spring connection between the convergent ends of said members within said spring casing and supported thereby, said spring casing being opened at opposite ends and the adjacent ends of the rod-like members being inserted in the open ends of said casing.

5. In combination with a flexible poster, a supporting structure there-for comprising rods engageable with the poster, said rods having shouldered ends, a tubular spring engaged over the shouldered end portions of 6. The combination with a flexible poster,

a supporting structure therefor, comprising rods engaged with the poster, said rods having end portions of two different diameters, a tubular connecting spring engage-clover the end portions of smaller diameter and a surrounding tubular spring over said first tnbular spring and engaged with the shouldered portion of larger diameter.

7. As a new article of manufacture, a supporting structure for flexible posters, comprising rods having end portions o'l ditferent diameters and tubular spring connectors ergaged over said portions of diiifei. nt diameter and one enclosing the other to re inforce and brace each other as said con nectors are bent in bringing the rods into angled relation. 7

In testimony whereof E affix my signature.
