Abstract

Un système porteur, de préférence de sacs à dos, comprend au moins deux bretelles porteuses (2, 3) attachées aux parties supérieure et inférieure du sac à dos (1) et conçues pour être en contact et entourer les épaules et la poitrine du porteur, en attachant le sac à dos sur le dos du porteur. Chaque bretelle (2, 3) s'étend en une courbe autour de la poitrine du porteur et les bretelles s'attachent l'une à l'autre par des lanières (12) disposées à des intervalles réglables et prédéterminés. Ces lanières traversent une pluralité d'orifices (11) disposés longitudinalement sur chaque bretelle. Les lanières (12) peuvent être tirées de la bretelle respective (2, 3) pour former des boucles (13, 15) qui peuvent être attachées ensemble à l'aide d'un dispositif de connexion (14) afin de fixer les bretelles (2, 3) sur la poitrine dans une position donnée.A carrier system, preferably a backpack, includes at least two carrying straps (2, 3) attached to the upper and lower portions of the backpack (1) and designed to be in contact with and surround the shoulders and chest of the carrier , by attaching the backpack to the back of the wearer. Each strap (2, 3) extends in a curve around the chest of the wearer and the straps are attached to each other by straps (12) arranged at adjustable and predetermined intervals. These straps pass through a plurality of orifices (11) arranged longitudinally on each strap. The straps (12) can be pulled from the respective strap (2, 3) to form loops (13, 15) which can be tied together using a connection device (14) to fix the straps ( 2, 3) on the chest in a given position.

Description

Carrying system/ preferably for rucksacks

The present invention relates to a carrying system, preferably for rucksacks, including at least two carrying straps attached to the upper and lower portions of the rucksack, and intended to bear against, and extend over the shoulders and chest of a wearer for positioning the rucksack against the back of the wearer.

The rucksacks so far available on the market are usually provided with leather or -fabric straps for positioning the rucksack against the back of the wearer. In order that these straps will not cut into the shoulders and chest of the wearer, thus causing discomfort, these straps are provided with different types of bearing pads. These pads have indeed relieved the cutting-in of the straps, but in spite of these measures there has been no solution to the problem of chafing under the arms of the wearer, and this chafing can be very irritating.

The present invention has the object of providing a carrying system of the type mentioned in the introduction, with which the disadvantages mentioned above have been eliminated. What is essentially distinguishing for the invention is that each strap extends in a curved configuration in over the chest of the wearer such that at the shoulder portion the straps extend mutually parallel as far as the upper portion of the chest, and then, preferably after a small curve towards each other, they curve sideways to their respective attachment points at the lower exterior portions of the rucksack, and in that each strap is provided with at least one thong extending through a plurality of eyelets or holes arranged along the strap, at least at its middle section, it being possible to pull out the thong into a loop at an optional height between two eyelets, and to a desired length for lockable coaction by a connection means with a loop formation on a thong arranged in a corresponding way on the other strap, for positionally fixing the positions of the straps in mutual relation on the chest of the wearer.

Due to the carrying system in accordance with the present invention, there is now avoided the chafing under the arms usually caused by the straps, since these may now be adjusted, both in height and sideways, i.e. towards each other,. in combination with an anatomic implementation of the straps.

The invention will now^' be described in detail with the aid of an embodiment and with reference to the accompanying drawing, on which

Fig. 1 illustrates a carrying system in accordance with the present invention, seen in a perspective view to one side from behind, and Fig. 2 illustrates the rucksack of Fig. 1 in a perspective view to one side from the front.

As will be seen from Fig. 1, the rucksack 1 includes two straps 2, 3 extending from, and being attached to, the upper portion 4 and to the respective exterior lower portions 4 , 5 to which they are also attached. A hip belt 7 with a quick-release fastener 8 is also attached to the portions 5 , 6 and is intended to be fastened round the waist of the wearer. The straps 2, 3 each have a curved configuration 9 at approximately half the height of the rucksack such that when the rucksack is worn the straps 2, 3 first extend mutually parallel over the shoulders of the wearer as far as the upper portion of the chest, and then, preferably after a further small inward curvature 10 towards each other, they diverge sideways in a curve to their attachment points at the lower exterior portions 5 and 6 of the rucksack. To provide a desired positional fixation of the straps 2/ 3 over the chest of the wearer, these straps have a plurality of eyelets or holes 11 in the longitudinal direction of each strap, at least at its middle section, for accommodating a thong 12, which may be pulled out between two consecutive holes 11 at an optional height into a loop configuration 13 to the desired length. The thong 12 is locked by a knot 16 at one of the outer, upper or lower holes 11 and the free end 17 of the thong 12 can run freely through the other outer hole 11. The length of the thong 12 is determined by a displaceably arranged clamping device 18 which, when the thong 12 is pulled out between two consecutive holes 11, comes into engagement with one of the outer holes 11. The loop which can be pulled out from the strap 2 is lockable by a connection device 14 to a corresponding loop 15, which can be pulled o_^ut from the thong on the other strap 3. The connection device 14 comprises .a snap hook 19, or the like, attached movably to the loop 13 and hookable on to the loop 15 on the other thong 12. If it is desired to position the straps 2, 3 closer to each other, it is only necessary to pull the free ends of the thongs 12 and move the clamping device 18 towards the outer holes 11 for the loops 13 and 15 to be smaller and the distance between the straps shorter. If it is desired that the straps 2, 3 be kept together and positionally fixed higher up on the chest, it is only necessary to move the hook 19 to a loop pulled out between two holes 11 higher up on the strap 2. A loop 15 is then pulled out on the thong on the strap 3 between two holes 11 such that it is at a corresponding height to the loop of the thong on the first strap 2.
