Abstract
Abstract A backpack and frame apparatus comprising a pair of tubular side bars and lateral cross members for supporting the backpack and upper terminus of the shoulder harness. A supporting belt adapted to be coupled about the user's waist and hips includes downwardly projecting panels disposed on diametrically opposed sides of the belt and adapted to lie substantially below the waist of the user. A supporting frame is coupled to the lower extensions of the belt and extends about the rear of the user, the support frame being reciprocally coupled to a pack frame cross member to provide independent movement between the pack frame and the support frame.

A backpack and frame apparatus comprising: (a) a frame including a pair of side bar members and upper and lower lateral cross members connecting said side bar members; (b) an upper support tube coupled intermediate a pair of upper cross members intermediate said side bar members; (c) a pair of shoulder straps, the upper ends thereof attached to said support tube; (d) hip belt means for encircling the waist of a user, said hip belt means including downwardly extending panels adapted to lie along the hips of the user, each of said panels including grommets for attachment thereto, said grommets being diametrically opposed to one another; (e) means for attaching the lower ends of said shoulder straps to respective ones of said side bar members substantially adjacent the waist of the user; (f) first and second axles journeled intermediate said side bar members in axial alignment with one another; (g) first and second beveled gears secured to the respective ends of said first and second axles in justaposition to one another; (h) a third beveled gear coupled intermediate said side bar members and adapted to rotate about an axis perpendicular to the axis of said first and second beveled gears, said third beveled gear being meshed with said first and second beveled gears whereby the rotation of one of said first or second beveled gears is transmitted to the other; and (i) first and second lever arms having first and second ends, said first ends coupled to the ends of said first and second axles opposite said first and second beveled gears, the second ends of said lever arms being secured to said grommets whereby reciprocating motion of said hip belt means will be transferred between said lever arms maintaining said frame substantially stationary and independent of movement of said hip belt means.
