INCLINING SUN CHAIR BACKGROUND or THE' INVENTION SUMMARY OF THE INVENTION The deck chair of the instant invention fulfills the above mentioned gap in the prior art by providing a deck chair having two hinged platforms on a support mechanism which permits the platforms to be oriented at a wide variety of angles relative to one another and relative to the ground or other supporting surface. The support mechanism includes a pair of reinforced legs depending from the upper platform and secured at any desired angular position by a pair of adjustable braces pivotally connected to the hinge joint between the platforms and engageable at different positions along their lengths with catch means provided on the legs. A pair of straps or chains connected to the lower platform may be engaged at various positions along their lengths either with catch means on the support legs or with catches on the upper platform. The chair was inspired by the needs of sunbathers and can be oriented in planar form to up to about 60 relative to the ground so that the user may catch the suns rays at the optional angle at the suns position.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation view of the chair in one position;

FIG. 2 is an enlarged sectional view taken on line 2-2 of FIG. 1;

FIG. 3 is a top plan view of the chair;

FIG. 4 is an enlarged sectional view taken on line 44 of FIG. 3;

FIG. 5 is a sectional view taken on line 5-5 of FIG.

FIG. 6 is an enlarged view taken on line 66 of FIG.

FIG. 7 is an enlarged sectional view taken on line 7-7 of FIG. 1; and

FIGS. 8-13 illustrate various positions into which the chair can be adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The deck chair has an upper platform 14 and a lower platform 16, these platforms each having

parallel sidewalls

18 and 20, respectively, and a plurality of parallel slats 22 mounted to the tops of the sidewalls. The slats and sidewalls can be of wooden construction and glued or nailed together in conventional fashion, the two platforms being pivotally connected to each other as by the bolts and wingnuts 24 joining the sidewalls. The upper platform may have a cushion head rest 26 mounted thereon.

The principal support for the chair is provided by a pair of legs 28 which are pivoted to generally central points on thesidewalls 18 of the upper platform by bolts 30, and a pair of cross braces 32 are mounted between the legs for lateral rigidity.

Two additional braces 34 are pivoted on the bolts 24 as shown in detail in FIG. 6, these braces having a plurality of spaced stations. along their lengths which are attachable to catches on'the legs, these stations being bores 36 in the preferred embodiment which are selectively engageable on bolts 38 extending from the legs. A pair of supports such as staps 40 are fastened at their forward ends to sidewalls 20 of the lower platform and have hooks 42 on their other ends which are engageable either in rings 44 on the chair legs or alternatively in the rings 46 on the sidewalls of the upper platform.'The straps have central buckles 48 so that they are adjustable in length. It is of course possible that rigid supports could be used in place of the flexible straps 40, or a pair of telescoping supports be used, but

flexible members are preferred.

FIGS. 8 through 13 show a few of the large number of positions that the chair may be made to assume by adjusting the straps and the braces 34. FIG. 9 illustrates a convex configuration of the chair in which a user might lie face down, and the straps have been replaced by a pair of chains 50. In FIG. 10, a position is illustrated in which the lower platform rests on the ground and is supported by protrusions 52 which extend from the sidewalls of the lower platform, and in FIG. 13 the protrusions 54 are also used so that the chair is fully reclined and supported slightly above the ground. In FIG. 11, the straps 40 are connected to the alternate rings 46, and in FIG. 12 the chair is shown in its collapsed position for storage in which the legs and braces 34 have been removed and the straps 40 are used to hold the chair in its collapsed state.

The lower portion of the lower platform is provided with pairs of spaced holes 56 in the sidewalls and a removable footrest 58 comprising a planar panel 60 having lateral mounting brackets 62 is bolted between the sidewalls. Different pairs of the holes 56 can of course be selected to alter the position of the footrest to accommodate the needs of different users.

The deck chair can thus be seen to be extremely versatile, compact when folded for storage, inexpensive and simple to construct, and of great utility especially to sun bathers.

I claim:

1. An adjustable deck chair comprising:

a. an upper platform and a lower platform connected together by a hinge joint to define an elongated deck portion of a chair;

b. leg means pivoted to said upper platform to support same above a generally horizontal surface;

2. Structure according to claim 1 wherein said elongated means is flexible.

3. Structure according to claim 2 wherein said brace means has a plurality of stations provided along the length thereof selectively engageable with a catch means on said leg means, whereby said brace means is securable in a variety of different positions on said leg 'said brace elements against said legs.

5. Structure according to claim 2 wherein said flexible means are of adjustable effective length.

6. Structure according to claim 5 wherein said elongated flexible means comprise a pair of chains and said leg means are provided with hooks to engage selected links of said chains, whereby the effective lengths of said chains are adjustable by selecting the links thereof engaged by said hooks.

8. Structure according to claim 7 wherein said footrest comprises a planar panel having parallel apertured 4 mounting brackets projecting from one side thereof and said lower platform is provided with a plurality of bores such that said panel is adjustable by virtue of being boltable to said lower platform at selected ones of said bores.

9. Structure according to claim 2 wherein said platforms each include a pair of elongated sidewalls, the

sidewalls of one platform being pivoted to the sidewalls of the other platform to define said hinge joint, the sidewalls of one of said platforms having downwardly projecting protrusions at both ends thereof and the sidewalls of the other of said platforms having downwardly projecting protrusions at the ends thereof remote from said hinge joint, whereby said deck chair defines a slightly elevated deck when both of the platforms thereof are laid on a horizontal surface.
