Embodiment Construction

[0022] Referring in particular to FIG. 8, a climber's or tramper's pack 2 in accordance with the present invention comprises a sac 3 which is of known type (apart from the addition of wings 4 as hereinafter described) which is supported by an internal frame 5 and which is provided with a harness 6 which includes a pair of padded shoulder straps 7 and a hip belt 8. The harness 6 is of known type apart from the novel features of the hip belt as described below.

[0023] Referring in particular to FIGS. 6 and 7, the frame 5 consists of a pair of spaced U-shaped portions 10, 11 which are inclined at an acute angle to each other and are spaced apart by a crossbar 12. The curved end of each U-shaped portions 10,11 is uppermost, and when the frame is inserted Into the sac 3, the U-shaped portions support the upper part of the sac.

[0024] The outer leg 10a, 11a of each U-shaped portion is connected to a flexible rod 13,14, the longitudinal axis of which is aligned with the longitudinal axis o...

Abstract

A pack which includes a sac, an internal frame for the sac, a shoulder harness and a hip belt; the frame includes a pair of spaced flexible rods positioned one on each side of the frame so as to extend down at least the lower part of the length of each side of the sac; tensioning means are secured between each flexible rod at or adjacent the end of said flexible rod, and an adjacent portion of the hip belt; each said tensioning means being adapted to move the corresponding flexible rod so as to bow and tension said rod and provide a relatively rigid weight transmitting connection between said rod and the corresponding portion of the hip belt; the arrangement being such that said movement of said flexible rods tends to lift the frame and the pack, decreasing the loading on the shoulder harness and increasing the loading on the belt.

Description

TECHNICAL FIELD [0001] The present invention relates to improvements in climber's or tramper's packs, and to frames for such packs. BACKGROUND ART [0002] A modern pack consists of a sac in which equipment may be carried, the sac being mounted on a frame, and a shoulder harness secured to the sac or to the frame. Since carrying a heavy load supported only from the shoulders can lead to backache or even to back damage, a majority of modern packs also include a hip belt which is connected to the sac or the frame, generally at or close to the base of the sac, to transfer some of the load from the shoulders to the hips. [0003] Although using a hip belt reduces the strain on the back, the belt itself can cause problems to the wearer, due to the way in which the human body moves when walking. [0004] When a human being walks, he leans backwards and forwards with each step (FIG. 1) and from side to side with each double step (FIG. 2). As he leans to the supporting side when taking a step the...
