Backpack frame and chair conversion kit

Abstract

A rigid frame type backpack and a kit of tubular segments for use therewith and convert the same to a chair. The kit includes a plurality tubular segments that can be detachably inter-connected by elastic cord means into a rigid assembly that includes a chair seat and a pair of chair front legs with such assembly being detachably securable to the backpack frame. The lower portion of the backpack frame provides the rear legs of the chair and above that a backrest for the occupant of the chair.

I claim: 
     
         1 . A backpack frame and chair conversion kit, comprising:
 a rigid backpack frame;   a first segregated group of longitudinal members;   a second segregated group of longitudinal members;   first coupling means in the respective first and second groups detachably interconnecting the longitudinal members into respective first and second generally rigid L-shaped units in which one leg of the respective units provides a chair seat side rail and the other a chair front leg;   at least two elongate rigid cross members;   second coupling means detachably connecting said cross members to the chair side rails thereby forming an assembly of a chair seat and pair of front legs; and   third coupling means detachably connecting said assembly to the backpack rigid frame and together therewith providing a chair readily assembled in situ.   
     
     
         2 . The backpack frame and chair conversion kit as defined in  claim 1  including additional elongate rigid brace members and coupling means associated therewith detachably inter-connecting the chair legs. 
     
     
         3 . The backpack frame and chair conversion kit as defined in  claim 2  wherein the longitudinal members in the respective first and second groups connect one to the next in end-to-end relation. 
     
     
         4 . The backpack frame and chair conversion kit as defined in  claim 3  wherein said first coupling means comprises having an end portion of one piece removably insertable in snug fit relation into an end portion another piece of the same group. 
     
     
         5 . The backpack frame and chair conversion kit as defined in  claim 1  including means loosely interconnecting the longitudinal members in the respective groups and thereby providing segregation of the same. 
     
     
         6 . The backpack frame and chair conversion kit as defined in  claim 1  including a flexible cord like member interconnecting the longitudinal members. 
     
     
         7 . The backpack frame and chair conversion kit as defined in  claim 6  wherein said cord like member comprises a bungee cord. 
     
     
         8 . A backpack frame and chair conversion kit, consisting essentially of:
 a rigid planar frame;   a first segregated group of tubular longitudinal members;   a second segregated group of tubular longitudinal members;   first coupling means in the respective first and second groups detachably interconnecting the longitudinal members therein into a generally rigid L-shaped unit in which one leg of the unit provides a chair seat side rail and the other a chair front leg;   at least two elongate rigid cross members;   second coupling means detachably connecting respective opposite ends of said cross members to the chair side rails, said cross members being spaced apart from one another thereby forming an assembly of a chair seat and pair of front legs; and   third coupling means detachably connecting said assembly to the backpack rigid frame at a position spaced upwardly from a lower end thereof whereby the frame portion there below provides rear legs of the chair and at least a portion there above a backrest.   
     
     
         9 . The backpack frame and chair conversion kit as defined in  claim 8  wherein said first coupling means in each of the respective first and second groups of longitudinal members comprises having an end portion of one piece insertable in close fit relation into an end portion of the next adjacent piece. 
     
     
         10 . The backpack frame and chair conversion kit of  claim 8  wherein said rigid planar frame comprises a backpack having a rigid inverted U-shaped frame. 
     
     
         11 .  8 . A backpack frame and chair conversion kit, consisting of:
 a backpack having a rigid planar frame;   a first and second group of said tubular longitudinal members providing a pair of chair seat side rails and a pair of chair front legs;   means flexibly interconnecting the longitudinal members one to the next in the respective groups and thereby segregating such longitudinal members from other chair forming longitudinal members;   means interconnecting the longitudinal members in the respective groups providing a pair of rigid generally L-shaped members;   at least first and second cross members securely detachably interconnecting said side rails; and   means detachably securely anchoring said chair side rails to said backpack frame legs at a position spaced upwardly from a lower end thereof whereby the backpack frame below and above such position provide respectively a pair of rear chair legs and a chair back.
