Carrier frame for back load

Abstract

A carrier frame is for a back load having an extended resilient element that extends in a closed loop and crosses itself in such a way that it forms a shoulder element, an anchor element and a hip element between the crossings. Segments of the element can be moved in relation to each other. The shoulder element has a shoulder fastening for shoulder straps, the anchor element is adapted for support of the back load, and the hip element has a hip fastening for a hip belt. The load is resiliently suspended in the carrier frame, which gives possibility of damping. The back load may be a pack bag in a rucksack, a child seat or another pack.

1 . A carrier frame for a back load comprising:
 at least one extended and resilient element which comprises at least one crossing where the at least one element in the carrier frame are moveable relative to each other,   
       wherein the at least one element is one continuous element that extends in a closed loop and crosses itself in such a way that it forms a shoulder element between an upper frame end and a first crossing, an anchor element between the first crossing and a second crossing, and a hip element between the second crossing and a lower frame end, the shoulder element has an upper fastening for shoulder straps, the anchor element is adapted for support of the back load, and the hip element has a lower fastening for a hip belt. 
     
     
         2 . The carrier frame according to  claim 1 , wherein the element is a hollow pipe. 
     
     
         3 . The carrier frame according to  claim 1 , wherein the ends of the element are put into a sleeve at the upper frame end. 
     
     
         4 . The carrier frame according to  claim 1 , wherein the resilient element comprises a number of shorter elements, where the ends of the shorter elements are put removably into sleeves, whereby the carrier frame can be assembled and disassembled. 
     
     
         5 . The carrier frame according to  claim 1 , wherein a first section of element has an arc which is bigger than the cross section at least at one crossing, whereby a section of the element is free to move in the arcs in the at least one crossing. 
     
     
         6 . The carrier frame according to  claim 1 , comprising additional crossings, whereby at least one comfort element is formed. 
     
     
         7 . The carrier frame according to  claim 1 , wherein the anchor element comprises a crossing and thereby is divided into sub elements. 
     
     
         8 . The carrier frame according to  claim 1 , wherein the anchor element comprises a damping element. 
     
     
         9 . A carrying system having a carrier frame according to  claim 1 , wherein the shoulder element is located in an upper fastening firmly connected to the shoulder straps, the hip element is located in a lower fastening firmly connected to the hip belt, and an anchor fastening is firmly connected to the back load and adapted to transmit forces from the load to the anchor element. 
     
     
         10 . The carrying system according to  claim 9 , wherein the upper fastening, the lower fastening and the anchor fastening are pockets of textile. 
     
     
         11 . The carrying system according to  claim 9 , wherein the anchor fastening comprises two pockets. 
     
     
         12 . The carrying system according to  claim 9 , wherein the back load is fastened to the anchor element with brackets.
