SADDLE ARRANGEMENTS FOR RUCKSACKS AND METHODS OF

MANUFACTURE

TECHNICAL FIELD

The present disclosure relates generally to rucksacks, for example to saddle arrangements for rucksacks that enable the rucksacks to be strapped to and supported by their respective users. Moreover, the present disclosure concerns methods for manufacturing aforementioned saddle arrangements. Furthermore, the present disclosure relates to methods for adjusting aforementioned saddle arrangements.

BACKGROUND

Rucksacks have been known for thousands of years, and provide an effective way to transport materials using human labour. However, human beings come in various sizes, heights and so forth. In order to cope with such variation, contemporary rucksacks are manufactured in a variety of different sizes, the suit children and adults as appropriate. Moreover, it is known that children via adolescence to adults, during which period their size and height changes rapidly. Rather than having to stock a large range of different sizes of rucksacks to cope with such different sizes, it has for a long time been desired to have a rucksack that is more adaptable in its ability to adapt.

EP0273087A1, 06071988, Garrino, discloses a solution where the straps are connected to a frame member which again can be fixed to the frame of the rucksack at different steps along length of the frame.

Of found prior art, publication EP0351333A1, 17.01.1990, Dofournet discloses a system where the upper point of fixture of the straps of the rucksack are adjustable longitudinal of the rucksack frame.

US5730347, 24.03.1998, Finot, and DE102004023665A1, 09.12.2004, Flem, show variations of the same.

A variation of this latter solution is found amongst other on a rucksack from producer NORRØNA®, the model called “PARA RANGER PACK 120+

However, these solutions will have a very limited range of adjustment on a small rucksack and therefor would require a rather sizable rucksack in order to make any sense. Also prior art shows the need of having a firm frame in order to work and not a soft backpack of small or medium size which have become a very popular product today.

Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks.

SUMMARY

The present disclosure seeks to provide an improved back strap carrying arrangement, namely a saddle arrangement for a rucksack that allows for a degree of adjustment to users that conventional rucksacks are unable to provide.

The present disclosure also seeks to provide a method for manufacturing an improved saddle arrangement for the rucksack, as aforementioned.

Figs. 19a, 19b, 20a, 20b, 21a and 21b show drawings of preferred embodiments according to the invention. The main saddle frame 200 comprise of a rigid og semi-soft unit which is to be fixed to a rucksack bag or anything for carrying on a human back. The frame 200 may also be part of a backpack 202 and its carrying portion. Dotted lines 202, illustrate any backpack, lines 204 associated carrying straps, and 206 straps on waist belt 220. When saddle frame 200 is made to fit a soft or semi soft bag, a support beam 210 is fixed in a longitudinal direction for strength of the frame 200. A waist belt 220 is made for sliding in a longitudinal manner, as illustrated by arrow 218, connected to the frame 200. The waist belt has a wide strap 222 which is slid through a passage, or tunnel 224 within the middle and upper longitudinal part of the frame 200. Strap 222 is longer than tunnel 224 and is folded back and downwards when securing the waist belt 220 at desired position as illustrated in Fig.19b, numeral 216. The design allows the user to adjust the waist belt 220 in the longitudinal position according to length of back or comfort. The waist belt 220 may also not be used. A waist belt padding 230 may then be removed from the waist belt and secured directly to the saddle frame 200.

Securing the waist belt 220 and strap 222 is done by the use of a hook and loop fastener system, also known as Velcro®. Velcro is fixed on to strap 222 at 223 and on outside of tunnel 224, at 225.

Also Velcro is used on frame 200 at 212 and on waist belt padding 230 unit at 232 for fixation to waist belt 220, at 214 or directly on to saddle frame 200, 212 when waist belt 220 is not wanted.

As seen in Fig. 19a, when waist belt 220 is mounted, it is secured by a bar 240 which engages in loops/track arrangement 226 of the waist belt 220 and secured in catches 217 of the frame 200. This allows for positioning of waist belt 220 within the length of loops/track arrangement 226.

As seen in Fig. 20a, and 20b, there are two elongated rigid track units 250 fixed apart on the lower part of saddle frame 200 in a longitudinal direction. A slide bar 252 is engaged perpendicular to the track units 250 and can slide along the track as illustrated by arrow 219. To the slide bar 252 is fixed a strap and lock unit flap 254, the flap adjustable as shown by arrows 259. This unit is used to lock the waist belt 220 to the saddle frame 200 and tracks 250, thus being adjustable as disclosed. Velcro on waist belt 220 at 214 and on flap 254, is preferable used.

Numerals 260, 262, 264, 266 refer to padding on saddle frame 200, waist belt 220 and waist belt padding 230 unit.

Figs. 21a and 21b show in more detail the slide bar 252 and track units 250. Fig. 21a illustrate a saddle frame 200, where track units 252 are of cylindrical shape and fixed to pockets/slots 256 on frame 200. Lock unit flap 254 is fixed on to bar 252 or is made as a one piece unit denoted slide and lock unit 255. The unit 255 may be motioned along track units as illustrated by arrow 219 and “opened” and “shut” as indicated by arrow 259. When waist belt 220 is in a position as seen in Fig. 19b the lock unit 255 flap 254 engages by Velcro 214 on waist belt 220. This enables the waist belt to be motioned along track units 250. Locking the waist belt 220 in the preferred position in the longitudinal direction of the frame and rucksack is done by flap 222, as shown in Fig. 19b.

Fig. 21b show an alternative embodiments of the track units 250, here denoted 270, having elongated holes for fixation to the frame 200 by means of a straps 272.

The embodiments, especially shown in Figs. 19a-21b, are designed for being made of strong textile materials, leather or artificial leather imitations, and also of soft plastic or rubber materials, whereas all materials are of types normally used for bags.
