Benefits of technology

[0014] wherein the width of the flexible member is smaller than a width of the side openings and extends through the passage via the side openings with portions of the flexible member extending upwardly from the side openings at an angle relative to the back panel, the angle of the upwardly extending portions being variable relative to the back panel to accommodate wearers having differing back lengths, and wherein the flexible member is substantially freely movable in a forward and rearward direction and a side to side direction relative to the base portion, over a range of differing angles of the upwardly extending portions, to enable shoulder movement of a wearer.

Problems solved by technology

This compromises stability and hinders performance in high motion sports.
This method of running through loops created significant friction in the movement of the interlinked web reducing the ease of movement of the shoulders.
This means that the flexible interlinking web will be pulled into the upper edge of the channel increasing the friction and thereby inhibiting the free movement of the shoulder straps and therefore the movement of the shoulders.
For wearers of short or long back lengths, the interlinking strap will be pulled into the top or bottom edges of the channel respectively, increasing friction and reducing the free movement of the shoulders.

second embodiment

[0055]FIG. 3 shows a second preferred embodiment of the backpack. Unless described below, the features and operation should be considered to be the same as those described above. In the second embodiment, the flexible member 14 has a substantially circular cross section. Preferably, the flexible member 14 has a smooth surface, and is preferably composed of low friction plastic material. Alternatively, the flexible member 14 may be a cord coated with a friction reducing material such as polytetrafluoroethylene. As outlined above, the flexible member is substantially non-compressible across its width. Preferably, the flexible member is substantially non-compressible along its length, and most preferably the flexible member is substantially non-compressible in every dimension.

[0056] A connector part 15 joins flexible member 14 to both webs 10 and 11. In this embodiment, the inner panel 5 of the base portion may be the same width from front to back as the outer panel 6. In this embodime...

third embodiment

[0058] In this third embodiment, the strapping arrangement has buckles and webs or straps connected to the shoulder harness, and the backpack has a pair of frame stays 16 located in the back panel. The stays are preferably positioned in a tapering generally V-shaped configuration being centrally located at the base of the back panel and laterally located in the upper area. A part of the upper section of each stay is exposed. These frame stays are held in position by fabric or web sleeves in the bottom and middle sections and at the top ends.

[0059] The base of the shoulder harness is fixed to the back panel behind a breathable outer back panel surface 17. The shoulder harness has webs 18 fixed to the central portion. Webs 18 are threaded through each buckle 19. Buckles 19 are linked to connectors 21 via webs 20. Connectors 21 are linked to and substantially free to slide up or down the exposed portion of frames 16 when the backpack is in use. For wearers of different back lengths, th...

fourth embodiment

[0062] In this fourth embodiment, buckles 19 are fixed to opposite ends of web 22. The central section of web or support strap 22 passes through, and is slidable relative to, a support loop 23, folding over as it passes through the loop in a V configuration. The loop 23 is fixed to the top of the pack via a web 24. As the shoulders move, web 22 slides substantially freely through the loop 23. This embodiment allows twisting of the shoulders relative to the hips, as well as sideways bending of the shoulders.

[0063] In the third and fourth embodiments, the webs 18 extend from the shoulder straps of the shoulder harness, and from the general regions of the shoulder straps that will extend over the wearer's shoulders in use. Preferably, the webs 18 extend from the shoulder straps level with or slightly forward of the tops of the wearer's shoulders in use. The configuration is preferably such that the webs 18 extend in a tangent from the top curvature of the shoulders of a wearer.

Abstract

A backpack has a backpack body having a front panel 2, side panels 3, a back panel 4, a top panel 1, an opening for inserting equipment into the pack, a base portion, and a hip or waist belt 8. The base portion has an inner panel 5 and an outer panel 6. The inner panel 5 and outer panel 6 define a passage therebetween which terminates in side openings. A shoulder harness has two shoulder straps 7. The shoulder straps are operatively connected to a flexible member 12 that is substantially non-compressible across its width, has a substantially smooth surface, and extends through the passage. The width of the flexible member 12 is smaller than the width of the side openings and extends through the passage via the side openings with portions of the flexible member extending upwardly from the side openings at an angle to the back panel. The angle of the upwardly extending portions is variable relative to the back panel to accommodate wearers having differing back lengths. The flexible member is substantially freely movable in a forward and rearward direction and a side to side direction relative to the base portion, over a range of differing angles of the upwardly extending portions, to enable shoulder movement of a wearer.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present patent application claims priority from New Zealand Patent Application No. 536593, filed on Nov. 17, 2004. FIELD OF THE INVENTION [0002] The present invention relates to backpacks in general and specifically to a shoulder strap harness system which allows free shoulder movement. BACKGROUND OF THE INVENTION [0003] A backpack is designed to carry a load on the human body. The load is transferred to the wearer's body via a set of shoulder straps and a hip belt. As the wearer walks, climbs, skis, skates or runs, the shoulders need to move freely so that the wearer's movements are not restricted. At the same time, the backpack must remain stably locked in position for the wearer to maintain balance. [0004] Backpacks that have shoulder straps fixed directly to the backpack will greatly restrict shoulder movement. When the wearer tries to move his shoulders, the shoulder straps will resist this movement. To move, the wearer has to ...
