Multipurpose chair structure
BACKGROUND OF THE INVENTION 
     This invention relates to a multipurpose chair structure intended primarily for use by hunters and other outdoorsmen. 
     A reasonably comfortable chair on a deer stand, in a duck blind or in a camp can be much appreciated. However, a chair can be a substantial burden when enroute on foot to the stand, the blind or the camp. If a chair, however, is light weight and serves other useful purposes aside from merely sitting, it may yet find substantial appeal. It is generally an object of this invention to provide a multipurpose chair structure which likely will have substantial appeal for hunters and other outdoorsmen. 
     SUMMARY OF THE INVENTION 
     Broadly the multipurpose chair of this invention comprises a generally planar upright frame which includes a pair of transversely spaced and vertically extending side members. A seat is mounted on the frame. The frame is provided with backrest means which extend between the side members and above the seat. The side members extend beneath the seat to provide a pair of transversely spaced legs. The pair of transversely spaced legs serve to support the seat for sitting when the frame is propped up against some fixed object.

     DESCRIPTION OF THE ILLUSTRATED EMBODIMENT 
     Referring to the drawings, the chair 10 of this invention generally comprises a portable, high backed, two-legged structure, particularly useful for hunters and other outdoorsmen. 
     The chair 10 includes a generally planar frame 11 comprising a pair of transversely spaced side rails 12 and 13 connected by a pair of vertically spaced transversely extending cross-members 14 and 15. The upper cross-member 14 is disposed generally adjacent to the upper end of the side rails 12 and 13, and is somewhat shorter in length than the lower cross-member 15 such that the frame 11 tapers to a narrower dimension at its upper end as perhaps best shown in FIG. 5. An arcuate member 16 connects the upper ends of the side rails 12 and 13 upwardly beyond the upper cross-member 14. The side rail members 12 and 13, cross-members 14 and 15 and arcuate member 16 all comprise aluminum box-section members which are welded together to form a relatively strong yet light weight frame structure 11. 
     The lower cross-member 15 is spaced from the lower end of side rails 12 and 13 a suitable distance for the mounting of a seat 17. The seat 17 is pivotally mounted to the lower cross-member 15 by a pair of transversely spaced hinges 18 as generally shown in FIGS. 1 and 7. The hinged seat 17 is pivotal between a forwardly projecting position generally normal to the frame 11 as shown in FIGS. 1 and 4 and a raised position generally paralleling the frame as shown in Fig. 3. 
     The lower end of the respective side rail members 12 and 13 comprise the legs 19 and 20 for the chair 10 and are each reinforced by an interiorly disposed adjunct member 21. The lower end portions of the aluminum box-section adjunct members 21 generally parallel to corresponding portions of the side rails 12 and 13 and are welded thereto. The upper portions of each adjunct member 21 is bent to extend forwardly to provide supports 22 for the seat 17. When the seat 17 is lowered to its position generally normal to the frame 11 for sitting, the underside of the seat rests upon the transversely spaced adjunct supports 22 as shown in FIGS. 1 and 4. The extreme lower end portions of the respective legs 19 and 20 are curved forwardly as shown at 23. When propped against a tree 24 or any fixed object, the curved ends at 23 provide for ground support for the legs 19 and 20 well under the seat 17 to enhance the stability of the chair 10. 
     The frame opening 25 formed between the transversely spaced side rails 12 and 13 and the vertically spaced cross-members 14 and 15 is laced with strapping material to provide a suitable backrest 26 for the chair 10. As perhaps best shown in FIG. 1, three (3) transversely extending cross-straps 27, 28 and 29 are disposed in vertically spaced relation between the cross-members 14 and 15. The respective ends of the straps 27, 28 and 29 extend across the front of the corresponding side rails 12 and 13 and continue around the outside and rear rail surfaces with attachment being made to the inside of the rails with an appropriate fastener 30, as shown in FIG. 6. As shown in FIGS. 1 and 5, the generally vertically extending straps 31 and 32 are spaced from each other and interwoven with the cross-straps 27, 28 and 29. Straps 31 and 32 are spaced from and generally parallel the adjacent side rail. The straps 31 and 32 extend vertically between and to the respective cross-members 14 and 15 for connection. The interwoven strapping material provides a backrest 26 offering considerable comfort to the user of the chair 10. 
     The two-legged chair 10 being generally comprised of an aluminum frame 11, a backrest 26 of strapping, and a seat 17 weighs less than ten (10) pounds and thus can be toted with relative ease by a hunter or other outdoorsman. However, to make that burden even easier, the chair 10 is outfitted for backpacking. A pair of transversely spaced adjustable carrying straps 33 and 34 are each secured between and to the respective cross-members 14 and 15 and project to the rear side of the chair 10. In service, the straps 33 and 34 extend over the shoulders of the bearer as generally shown in FIG. 2. 
     As further shown in FIG. 2, the chair 10 may serve as a support frame for the backpacking of other materials and gear. As shown, the seat 17 may be lowered to project generally normal to the frame 11 to provide good support for the load. The relatively wide stance for the legs 19 and 20 as well as the forward projection of the leg ends at 23 generally preclude bumping against the bearer&#39;s legs and clothes snagging when enroute. The forwardly curved ends at 23 for the legs 19 and 20 also serve to help avoid hang up by brush when traversing brushland. 
     As shown in FIG. 3, the chair 10 can also serve as the travois for larger game or other type loads. As a travois, the seat 17 may be pivoted upwardly to generally parallel the frame 11, if desired, and the arcuate member 16 at the upper end of the chair 10 serves as a strong handle for dragging by one (1) or more persons. If desired, the carrying straps 33 and 34 may be employed to secure the load onto the travois. The curved ends at 23 for the chair legs 19 and 20 provides the travois with ski-like bearing members to somewhat reduce the friction on the drag. 
     For hunters and other outdoorsmen, the chair 10 can be a source of relative comfort on reaching the stand, the blind or the camp. If need be, the chair 10 can also be useful enroute thereto. 
     Various modes of carrying out the invention are contemplated as being within the scope of the following claims particularly pointing out and distinctly claiming the subject matter which is regarded as the invention.
