Definitions

  • the present invention relates to a balanced backpack, of the type comprising bag containers supported on the shoulders of a user by suitable straps, in particular shoulder straps.
  • backpacks are a practical solution for carrying items, because they allow to discharge the weight of the latter on a sturdy load bearing structure, i.e. the user's back, concomitantly freeing the hands and allowing a remarkable freedom of motion, attained by firmly securing the backpack-associated container to the back, using straps and the like.
  • the backpack evolved in climbing or military contexts, has found ample scope in uses generally associated to free time, varying its shapes and dimensions and ensuring itself an important niche in the schoolbag field.
  • figure 7B of the annexed drawings illustrating the position assumed by a body carrying a backpack of average heaviness with respect to a situation without loads, illustrated in figure 7A.
  • This unbalancing inherent to the use of a backpack is enhanced, if possible, by the fairly widespread custom of carrying the backpack by slinging it on a single shoulder, thereby causing also a lateral unbalance.
  • Another incentive to the unbalance is represented by a further designing trend that is planned out to adjust to small-sized backs and proposes the extending of the backpack in a direction perpendicular to the back, taking further away the barycenter of the load from the line represented by the spine.
  • the technical problem underlying the present invention is to provide a backpack allowing to overcome the drawbacks mentioned with reference to the known art.
  • the main advantage of the balanced backpack according to the present invention lies in allowing an appropriate weight distribution, with a front-rear balance as well as a side balance.
  • the use of such a backpack forces the user to assume a correct posture as in figure 7C, with effects that can be propaedeutic to the healthy growth of a bone structure, and even, in some cases, propaedeutical.
  • said use makes the user's carriage more elegant and slender.
  • the balanced load backpack used by a user paces being equal, induces a lower heart rate and accordingly a lower oxygen consumption, ensuing from a smaller mechanical work and effort.
  • the two bag containers could form a single bag or a single backpack when suitably joined by zippers, strings, Nelcro ⁇ , etc.
  • FIG. 1 A and IB are perspective views of a rear bag container associated to a backpack according to a first embodiment of the invention
  • FIGS. 2A and 2B are perspective views of a front bag container associated to a backpack according to a first embodiment of the invention
  • figures 3 A and 3B are perspective views illustrating the use of the backpack of the preceding figures 1 A to 2B;
  • FIGS. 4A and 4B are perspective views of a rear bag container associated to a backpack according to a second embodiment of the invention.
  • FIGS. 5A and 5B are perspective views of a front bag container associated to a backpack in accordance with a second embodiment of the invention.
  • FIGS. 6 A and 6B are perspective views illustrating the use of the backpack of the preceding figures 4 A to 5B;
  • figures 7A, 7B and 7C illustrate the distribution of the barycenters of the various body parts of a user, implemented without backpack, with a traditional backpack and with a backpack according to the invention, respectively;
  • figure 8 shows the pattern of the cardiac profiles of a user in the three cases illustrated in the preceding figures 7A, 7B and 7C;
  • figures 9A and 9B are perspective views of a rear bag container associated to a backpack according to a third embodiment of the invention.
  • figures 10A e 10B are perspective views of a front bag container associated to a backpack according to a third embodiment of the invention.
  • figures 11A and 1 IB are perspective views illustrating the use of the backpack of the preceding figures 9 A to 10B;
  • a first embodiment of a balanced backpack according to the invention is generally indicated by 1. It comprises a sack-shaped rear bag container 2 of a basically hiking type. It has a top closure flap 3, side pockets 4, a rear pocket 5 and a top handle 6.
  • the rear bag container 2 is associable to a bust by means of a pair of shoulder straps, both indicated by 8, said rear bag container being located symmetrically with respect to said shoulder straps 8.
  • said shoulder straps 8 branch out from the top portion of the bag container 2 and end each with a respective first fastening member 9, e.g. of the rapid fastening type.
  • the shoulder straps 8 could be padded and in turn comprise further pockets.
  • the fastening member may be of any type whatsoever.
  • the backpack 1 comprises a front bag container 10, it also sack-shaped and of a basically hiking type. It has a top closure flap 11 and side pockets 12. In this case as well, it is proposed that such a front bag container 10 could be made according to any typology, with pockets, openings, strings, hooks, nooses etc. to meet hiking demands.
  • Said front container 10 has, in its top portion, a strap 13 ending with second fastening members 14, apt to cooperate with said first fastening members 9.
  • Said fastening members when cooperating in fastening, implement a fastening point 15 associated to said shoulder straps 8 and located frontally to the bust in a symmetrical position. Moreover, when the front bag container 10 is fastened to said fastening point 15, the load associated to the container 10 is charged thereon. Thus, the weight associated to both the containers 2, 10 is located symmetrically with respect to the shoulders, the spine and the bust in general.
  • each container has an average filling volume, usually expressed in liters, to which there is related an average carriable weight, due to the average specific weight of the material usually carried (clothing items, books, climbing gear, etc.).
  • the weight loadable in each bag container 2, 10 with regard to the volume of the bag containers has a rear/front ratio ranging from 2.0 to 0.8. Therefore, the rearward-associated weight could be up to twice the frontward- associated one, or, at the other limit value, about the same.
  • said ratio ranges from 1.5 to 1.0.
  • each bag container 2 comprises, at the bottom portion of each bag container 2, 10, straps 16 or equivalent means, provided with suitable fasteners 17, to join the containers 2, 10 bottomwise therebetween and at the user's sides.
  • such a backpack 1 may be adjusted to male or female anatomy, e.g. by providing the length of the shoulder straps 8 to be adjustable.
  • the fastening point 15 hangs at the center of the bust and the front bag container 10 may be worn at any height, hence even below the breast.
  • the sole rear container 2 could be worn as a backpack by means of shoulder straps implemented with the joining of the respective shoulder straps 8 and of the corresponding straps 16, with the joining of the respective fastening means 9, 17.
  • a satchel-shaped rear bag container 2 of the type basically indicated for the carrying of schoolbooks and notebooks. It has a top closure flap 3, a rear pocket 5 and a top handle 6.
  • a rear bag container 2 could be made according to any typology, with pockets, openings, containers for portable phones, radios, sound reproducers, etc., to meet free time or school time demands.
