Backpack Strap Attaching Structure

Abstract

A backpack strap includes a strap main body, an upper end of which is connected to a backpack frame, a pad attached to the strap main body on a user side, and a contact state holding unit holding an upper end of the pad in contact with the backpack frame. Upper portions of the strap main body and pad are spaced apart from each other by a specified distance. The upper end of the pad has a shape and a strength that is, when contacting the backpack frame, able to prevent the backpack strap from falling sideways. Due to a tensile force of the upper portion of the strap main body and a stiffness of the upper portion of the pad, the upper portion of the pad is held in a projecting state with the upper end of the pad acting as a support point.

1 . A backpack strap attaching structure that attaches a backpack strap to a backpack frame,
 wherein the backpack strap includes
 a strap main body, an upper end of which is connected to the backpack frame, 
 a pad attached to the strap main body on a user side of the strap main body, and 
 contact state holding means that holds an upper end of the pad in contact with the backpack frame, 
   wherein an upper portion of the strap main body and an upper portion of the pad are spaced apart from each other by a specified distance,   wherein the upper end of the pad is made to have a shape and a strength such that, when the upper end of the pad is in contact with the backpack frame, the backpack strap is able to be prevented from falling sideways, and   wherein, when the backpack frame is not being carried on the back of a user, due to a tensile force of the upper portion of the strap main body and a stiffness of the upper portion of the pad, the upper portion of the pad is held in a projecting state with the upper end of the pad acting as a support point.   
     
     
         2 . The backpack strap attaching structure according to  claim 1 ,
 wherein a hole is formed in the backpack frame,   wherein the contact state holding means includes an auxiliary strap attached to the upper end of the pad, and   wherein the auxiliary strap is threaded through the hole and secured to a specified position.   
     
     
         3 . The backpack strap attaching structure according to  claim 2 ,
 wherein a bar portion is formed in an upper portion of the backpack frame, the backpack strap being attached to the bar portion,   wherein the upper end of the strap main body is hooked around the bar portion and fastened with a metal connection retainer,   wherein a winding strap is attached to an end of the auxiliary strap, the winding strap extending in a direction that intersects the auxiliary strap, and   wherein the auxiliary strap having been threaded through the hole is hooked around the bar portion, and the winding strap is wound around and secured to the strap main body so as to cover the metal connection retainer.   
     
     
         4 . The backpack strap attaching structure according to  claim 3 ,
 wherein the metal connection retainer is secured to the upper end of the strap main body, the metal connection retainer having a slit through which the strap main body is threaded from a lateral direction.   
     
     
         5 . A backpack strap comprising:
 a strap main body, an upper end of which is connected to a backpack frame;   a pad attached to the strap main body on a user side; and   contact state holding means that holds an upper end of the pad in contact with the backpack frame,   wherein an upper portion of the strap main body and an upper portion of the pad are spaced apart from each other by a specified distance,   wherein the upper end of the pad is made to have a shape and a strength such that, when the upper end of the pad is in contact with the backpack frame, the backpack strap is able to be prevented from falling sideways, and   wherein, when the backpack frame is not being carried on the back of a user, due to a tensile force of the upper portion of the strap main body and a stiffness of the upper portion of the pad, the upper portion of the pad is held in a projecting state with the upper end of the pad acting as a support point.
