Title: Suitcase with a back pack adaptor

Description:
I have invented a new and novel suitcase with a back pack adaptor. This adaptor can be placed in the suitcase when the suitcase is not being worn on the back of the user as a back pack. A hiking pack sack may be attached to the rear surface of the back pack adaptor for use on short trips in wilderness areas while the back pack adaptor when inserted in the suitcase permits the suitcase to be carried in the conventional manner in urban situations. 
    
    
     My invention can be understood in view of the accompanying figures. 
     FIG. 1 is a side view of the back pack adaptor mounted on a person bearing the suitcase. 
     FIG. 2 is a side view of the suitcase containing the adaptor being carried in the conventional urban manner. 
     FIG. 3 is a top view looking into the suitcase opened showing the storage of the back pack adaptor in the suitcase. 
     FIG. 4 is a perspective view of the back pack adaptor being connected to the suitcase. 
     FIG. 5 is a close up of the connection of the canvas panel to the back pack frame. 
     FIG. 6 shows the connection of the pack sack to the frame as seen from the inside of the pack frame. 
     FIG. 7 is a view of the back pack adaptor as seen from the rear. 
    
    
     With regard to FIGS. 1, 2, 3, 4, and 5, a man 10 can place shoulder straps 12 and 13 and a waistband 14 which are attached to a pack frame 16 around his body. On the rear of the molded plastic pack frame 16 a pack sack 18 can be supported. Slots 20 and 22 in the pack frame 16 can accept mounting straps 24 and 26 which are pop riveted to a steel suitcase 28 by pop rivets 27 and can go around the suitcase 28 to secure the suitcase to the back of the pack frame 16 so that the person 10 can carry the suitcase 28 as a back pack. The handle 30 on the top of the suitcase 28 permits the user 10 to also carry the suitcase 28 in the conventional manner. 
     A canvas panel 32 can be attached to the front of the pack frame 16 by straps 34 and the straps 34 can be connected 36 between the grommets 37 in the canvas panel 32 and the pack frame 16 to form a continuous supporting network so that the canvas panel 32 can comfortably rest against the user&#39;s back. 
     With regard to FIGS. 6 and 7, a grommet 42 in the edge 38 of the pack sack 18 can engage a hook 44 attached to the back of the pack frame 16 and protruding through a hole 40 formed by the frame 16 to hold the pack sack 18. 
     The pack frame 16 can be made of a laminated wood construction which is very strong and durable or molded from plastic and the suitcase can be of the molded plastic type which is light and strong or of the steel type such as an American Tourister suitcase. 
     Having described a preferred embodiment of my invention, it is understood that various changes can be made without departing from the spirit of my invention, and, I desire to cover by the appended claims all such modifications as fall within the true spirit and scope of my invention.
