Abstract:
A pack frame made of metal tubing that readily interfits together for easy assembly or disassembly, shoulder straps for support from a person&#39;s shoulders and a storage bag attachable to a lower end of the frame.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates generally to sport hunters&#39; equipment. More specifically, it relates to backpacks or pack boards on which hunters can conveniently carry harvested game back to their camp or vehicle. 
     2. Description of Prior Art 
     It is well known to all persons such as hunters, hikers and others who are experienced in backpacking of heavy loads, that a rigid backpack frame is conventionally used with a canvas stretched across it for resting comfortably against a wearer&#39;s back. Such backpack frame carries the weight high up so a person can walk erect without need to lean forward, and thus does not tire even after long distances because the weight is on the shoulders and not on the back. However, when not in use carrying a load, its size hinders a person&#39;s free walking movement. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is a principal object of the present invention, to provide a portable pack frame that can be readily taken apart when not needed to transport a load, so that it may be stowed in a small storage bag commonly termed by hunters as a &#34;fanny pack&#34; for easy carrying. 
     Other objects are to provide a portable take apart pack frame which is simple in design, inexpensive to manufacture, rugged in construction, quick and easy to assemble or disassemble and efficient in operative use. 
     These and other objects will be readily evident upon a study of the following Specification and the accompanying Drawing.

     DETAILED DESCRIPTION 
     Referring now to the drawing in greater detail, and more particularly to FIGS. 1 to 6 thereof, at this time, the reference numeral 10 represents a portable take apart pack frame, incorporating the present invention, and which includes a lower sub-assembly frame unit 11, an upper sub-assembly frame unit 12 and a pair of extension bars 13 therebetween. The parts are made preferably of strong, light weight, tubular metal. Each unit 11 and 12 comprises an arcuate end tube 14 and a pair of side tubes 15 welded together at their ends into a general &#34;U&#34;-shape, and an arcuate cross-brace 16 between the free ends of the side tubes. The free end of the side tubes have openings 17 for receiving ends 18 of the bars 13 when assembling the pack frame 10. The arcuate members 14 and 16 bow outwardly toward a direction which forms a rear side of the pack frame. A detent 19 on the side tube snap fits in an opening 20 on the end tube for locking the pack frame in assembled position. 
     A rearwardly projecting, short stub tube 21 welded on each side tube serves to secure a canvas web 22 around the frame by being received in an opening 23 provided for it on the web. The webs serve to rest against a person&#39;s back comfortably. Ends 23a of the webs are attached together by lacings 25 through lace holes 24 on the web. 
     A pair of shoulder straps 26 are attached to the pack frame by means of a hole 27 on an upper end of the strap being secured by clevis pins 32 and holding wires 33 on the upper tube 14, and a lower end of the strap being fitted through a ring 29 pivotally attached to the lower unit. The strap includes a buckle 30 so to be adjustable in length. 
     When the pack frame is in use carrying a load, then a storage or &#34;fanny&#34; bag 31 is attached to the lower unit by means of clevis pins 32 and a holding wire 33. A strip of material on the bag has grommetted holes to receive the pins for securement thereto. The bag serves to support a lower end of a load carried on the pack frame. 
     As shown in FIG. 6, the pack frame may be assembled to form a chair 35 by fitting tubes 13 into stub tubes 21 of the upper and lower units. One unit rests on a ground and a person sits on the web of the upper unit. 
     As shown in FIG. 7, a modified design of pack frame 10a is generally the same as pack frame 10 except that instead of the above described rods 13, the device includes a plurality of interconnectable rods 13a on each side and a plurality of webs 22, so as to selectively also form a litter or stretcher for carrying a wounded comrade hunter or big game out of a wilderness. 
     While various other changes may be made in the detail construction, it is understood that such changes will be within the spirit and scope of the present invention as is defined by the appended claims.
