A pack frame for hikers formed primarily of interconnected, hollow, tubular members and including in one embodiment a pivoting connector between a lower hip-engaging portion of the pack frame and an upper shoulder-engaging portion of the pack frame such that the upper and lower portions of the pack frame may pivot with respect to each other about the connector responsive to the motion of a hiker\s hips and shoulders. A pack bag is disclosed having a pleated, connecting portion whereby the upper portion of the bag may pivot with respect to the lower portion. Also disclosed is a height-adjustable pack bag adapted to accommodate loads of varying size. A pack frame is also disclosed having segmented, vertically extending, laterally spaced, tubular side members, the segments of each side members being joined together by a flexible joiner member such that the upper portions of the tubular side members may resiliently tilt with respect to the lower portions. A flexible connecting joint for tubular members including an inner spring core substantially surrounded by a resilient covering which may be readily shaped to conform to the internal configuration of the tube members to be joined together.

An improved load carrying pack frame for hiking comprising: a hip portion forming the lower portion of the pack frame adapted to be connected to a wearer\s hips; a shoulder portion forming the upper portion of the pack frame adapted to be connected to a wearer\s shoulders; pivot means securely interconnecting with said hip portion and said shoulder portion at a point above said wearer\s hips and below said wearer\s shoulders to simultaneously interconnect said hip portion and said shoulder portion and permit said hip portion and said shoulder portion to pivot laterally with respect to each other about said pivot means without generating reactive countermovements responsive to the relative movement of said wearer\s hips and shoulders such that the load carried by said hip portion dynamically follows the movement of the wearer\s hips and such that the load carried by said shoulder portion dynamically follows the movement of the wearer\s shoulders; said pivot means being adapted to prevent relative rotational movement between said shoulder portion and said hip portion of said pack frame about an axis longitudinal of said pack frame.
