Backpack frame insert

Abstract

A backpack suspension apparatus is provided. The backpack suspension apparatus includes a frame, a material suspended between elements of the frame, and means for releasably holding the frame between a back of a user and a backpack.

What is claimed is: 
     
         1 . A pack suspension apparatus, comprising:
 a frame;   a first material and a second material suspended between elements of the frame; and   one or more attachment configured to hold the frame between a back of a user and a pack such that the pack may still be worn by the user when the pack suspension apparatus is detached from the pack,   wherein the first material is suspended between the elements of the frame such that it contacts the back of the user and the second material is suspended between the elements of the frame such that it contacts the pack, and   wherein the frame creates a space between the first material and the second material such that a main body of the pack does not contact the first material and the back of the user.   
     
     
         2 . The apparatus of  claim 1 , wherein the one or more attachment comprises at least one fixture releasably attaching the frame to at least one shoulder strap of the pack. 
     
     
         3 . The apparatus of  claim 1 , wherein the one or more attachment comprises at least one strap circumscribing the pack. 
     
     
         4 . The apparatus of  claim 1 , further comprising:
 a padded material coupled in at least one place to one or more of the frame, the first material, and the second material.   
     
     
         5 . The apparatus of  claim 1 , wherein the first material suspended between the elements of the frame is configured to permit the passage of fluid media from a first side of the first material to a second side of the first material. 
     
     
         6 . The apparatus of  claim 1 , further comprising:
 at least one strap on the frame selected from the group consisting of hip straps and shoulder straps.   
     
     
         7 . The apparatus of  claim 1 , further comprising:
 at least one releasable attachment configured to attach at least one portion of the first material and the second material suspended between the elements of the frame to the frame in at least one place.   
     
     
         8 . The apparatus of  claim 1 , wherein the first material is closer to the user's back than the second material. 
     
     
         9 . The apparatus of  claim 1 , wherein the frame is collapsible. 
     
     
         10 . The apparatus of  claim 1 , wherein the frame includes a protrusion and wherein the protrusion creates the space between the first material and the second material. 
     
     
         11 . The apparatus of  claim 1 , wherein the first material and the second material are suspended between the elements of the frame under tension and the first material is a mesh. 
     
     
         12 . The apparatus of  claim 1 , wherein the pack includes shoulder straps. 
     
     
         13 . The apparatus of  claim 12 , wherein the pack is a backpack. 
     
     
         14 . A method for increasing comfort of a pack, comprising:
 providing a separate pack and a separate pack frame insert, the pack frame insert having a frame and a first breathable material and second material coupled to the frame;   placing the pack frame insert between a user and the pack,   wherein the pack may still be worn by the user when the pack frame insert is detached from the pack;   wherein the first breathable material is coupled to the frame such that it contacts the back of the user and the second material is coupled to the frame such that it contacts the pack, and   a space is provided between the first breathable material and the second material such that a main body of the pack does not contact the first material and the back of the user.   
     
     
         15 . The method of  claim 14 , further comprising:
 detaching the pack frame insert from the pack; and   attaching the pack frame insert to another pack.   
     
     
         16 . The method of  claim 14 , wherein the frame includes a protrusion and wherein the protrusion creates the space between the first breathable material and the second material, and
 wherein the first breathable material and the second material are coupled to the frame under tension.   
     
     
         17 . The method of  claim 16 , wherein the pack is a backpack. 
     
     
         18 . A pack frame insert, comprising:
 a structure configured to be removably attached to and detached from a pack and disposed between a back of a user and the pack such that the pack may still be worn by the user when the pack frame insert is detached from the pack; and   a first material and a second material suspended between elements of the structure,   wherein the first material is suspended between the elements of the structure such that it contacts the back of the user and the second material is suspended between the elements of the structure such that it contacts the pack, and   wherein the structure creates a space between the first material and the second material such that a main body of the pack does not contact the first material and the back of the user.   
     
     
         19 . The pack frame insert of  claim 18 , wherein:
 the structure includes a protrusion;   the protrusion creates the space between the first material and the second material;   the first material and the second material are suspended between the elements of the structure under tension; and   the pack is a backpack.
