Adjustable load carrier device

摘要

An adjustable device for supporting a load includes a belt for fastening about a user's waist. A rod includes two rigid elements. One of the elements is longitudinally slidable relative to the other element so as to adjust a length of the rod. A lower end of the rod is attachable to the belt and an upper section of the rod is attachable to a shoulder harness that is placeable on the user's shoulders for carrying the load. A control is operable by the user when carrying the load to unlock a locking mechanism that, when locked, fixes the length of the rod. When the control is operated concurrently with movement of the user's shoulders relative to the user's waist, the length of the rod is changed to adjust a distribution of a weight of the load between the user's shoulders and waist.

1. An adjustable device for supporting a load, the device comprising:
a belt for fastening about a waist of a user; a rod including two rigid elements, one of the elements being longitudinally slidable relative to the other element so as to adjust a length of the rod, the rod further including a locking mechanism that is operable to prevent sliding of the slidable element so as to fix the length of the rod, the locking mechanism including, on one of the rigid elements, teeth that are extendible to engage corresponding fixed teeth on the other rigid element so as to lock the locking mechanism, the extendible teeth being mounted on an arm that is rotatable outward to engage the fixed teeth, the locking mechanism further including a wedge that is slidable to one position to press the arm outward and to another position to allow the arm to rotate inward, a lower end of the rod being attachable to the belt and an upper section of the rod being attachable to a shoulder harness that is placeable on the user's shoulders for carrying the load; and a control that is operable by the user when carrying the load to unlock the locking mechanism, such that, when the control is operated concurrently with movement of the user's shoulders relative to the user's waist, the length of the rod is changed to adjust a distribution of a weight of the load between the user's shoulders and waist.
