Definitions

  • the present invention relates to a backpack specially intended for use by schoolchildren, whereby the combined weight of the backpack and its contents is distributed across the user's shoulders in a rationalized fashion to prevent the assumption of undesirable bodily attitudes apt to cause discomfort, pain, and eventually lead to muscular and skeletal deformities particularly among young users.
  • This invention is directed to remedy the above-outlined situation by providing a backpack attachment, whereby the backpack weight is better distributed across the user's shoulders and the user is relieved of the constraint to lean unnaturally under the backpack weight.
  • this attachment makes a heavily loaded backpack more convenient to carry for a given effort.
  • an attachment for backpacks comprised of a bag-like body and a pair of shoulder straps, in particular school attendant's backpacks, being characterized by two curved members effective to stiffen substantially the shoulder strap sections that lie closest to the top of the bag-like body.
  • the curved members are preferably substantially inflexible parts mounted either in place of the shoulder strap section (T) that lies closest to the top of the bag-like body (CS), or otherwise associated with said section.
  • substantially inflexible curved members have their undersides lined with a soft yielding material for improved user's comfort.
  • the attachment of the invention comprises a pair of substantially inflexible curved members, each a one-piece construction. These members may have a hollow interior for slipping over said shoulder straps, or may have one end hinge-connected to a holder , which can be fixed on the upper region of the bag-like body of the backpack, and the other end connected to the shoulder straps.
  • the attachment of the invention comprises a pair of substantially inflexible curved members which are formed of several pieces jointed together. These members may comprise hollow pieces adapted to be slipped over the shoulder strap, or the leading one of the jointed hollow pieces may be attached to the top of the bag-like body of the backpack and the trailing one to the shoulder strap. Alternatively, the leading one of the jointed pieces of each member may be attached to the top of the bag-like body of the backpack, and the shoulder strap may extend from said leading piece through the other pieces.
  • the attachment of the invention comprises members that are each formed of several, preferably shaped pieces adapted to engage releasably with a shoulder strap, at least one of them being affixed to the strap.
  • the former pieces of said members may be engaged with the shoulder straps by means of releasable hoops, whereas the latter pieces are engaged by means of a releasable camlock device.
  • this attachment version includes arrangements for locking the jointed pieces of each member into a set angle to one another. The angular position of the jointed pieces of each member is thus made adjustable.
  • the locking device is mounted on one side of the individual jointed pieces, and comprises a gear wheel and a lockable spring-biased slider having an end jaw for engagement with the teeth of the adjacent piece wheel.
  • Figure 1 is a perspective view of one of two attachment members in a first embodiment of the invention
  • Figure 2 is a view, similar to Figure 1 , of one of the two attachment members in a second embodiment of the invention
  • FIGs 3 and 4 show two modifications of the embodiments of the invention shown in Figures 1 and 2, respectively;
  • FIG 5 is another modification of the embodiment of the invention shown in Figure 2;
  • Figure 6 shows a third embodiment of the invention, of enhanced practical value
  • FIGS 7 and 8 are two detail views, taken at 90 degrees from each other, of the attachment shown in Figure 6;
  • Figure 9 is a perspective view illustrating the way that the attachment of Figure 1 is applied to an ordinary backpack
  • Figure 10 is a perspective view illustrating the way that the attachment of Figures 6 and 8 is applied to an ordinary backpack.
  • Figure 11 shows a backpack, incorporating the attachment of the invention, as carried by a girl on her back.
  • Figure 1 1 showing the enhanced set of a backpack according to the invention, and the improved bodily attitude of a girl B carrying on her back a backpack Z which is equipped with the stiff curved members forming the attachment M of this invention.
  • Such curved members can replace or be associated with the sections of shoulder straps T that lie closest to the upper region of the bag-like body CS of the backpack Z.
  • a pair of substantially inflexible curved members 1 are formed of one piece each.
  • the members 1 comprise hollow curved pieces 2 of wood, metal, or plastics, which are adapted to be slipped over each shoulder straps T of a commercially available backpack, as shown in Figure 8, to contact the top rear wall of the bag-like body S of the backpack Z.
  • the underside of the hollow pieces 2 is lined with a soft yielding material for more comfortable contact with the user's shoulder.
  • the curved members 1 again comprise curved pieces 2A of wood, metal, or plastics, but need not be of hollow construction. These pieces are hinge-connected to holders 4 that can be secured in areas where the shoulder straps are usually hung.
  • This design is especially suitable for the manufacture of new backpacks, whereas it is not adapted for modifying according to the invention those backpacks which have already been manufactured. It requires, in fact, that the affected areas of the bag-like body wall be provided, by means of any appropriate mechanical means, with holders 4, in order for them to get stiffened .
  • the stiffening effect can be obtained in any of several ways, e.g. by providing additional metal or plastics plates or by providing the bag-like body CS of the backpack Z with a rigid or semirigid material wall to which the shoulder straps T can be connected.
  • the shoulder straps are made fast here to the end of the piece 2 A away from the holder 4.
  • the angled set of the pieces 2 A relative to the holders 4 can be adjusted and maintained by a device, not shown, in order to tailor the backpack attachment to fit a user's anatomy.
  • a pair of substantially inflexible curved members 1 are used which comprise several pieces jointed to one another. These members 1 may comprise hollow pieces 5 adapted to be slipped over the shoulder straps of the backpack as shown in Figure 2.
  • the leading one 7 of the hinge- connected pieces 6 in each member 1 is affixed to a stiffened area at the top of the bag-like body CS of the backpack Z, with the shoulder strap fastened to the trailing one 8 of said pieces 6.
  • the leading one 9 of said hinge-connected pieces 6 in each member 1 is provided much longer than the others for more secure connection to the wall of the bag-like body CS of the backpack Z, and the shoulder strap 10 extends from the leading piece 9 through all the others 6, it being connected to such pieces in a suitable manner to produce the curved pattern of the member 1 shown in Figure 5.
  • the invention is embodied most effectively by the backpack attachment having ( Figures 6 to 8) two members 1, each comprised of several stiff shaped pieces 11 of relatively small thickness adapted to be associated with the backpack shoulder straps in a detachable fashion. Some of the pieces 1 1 are loosely associated with a respective one of the shoulder straps (not shown in Figures 6 to 8) by releasable hoops formed by a pair of strips 12 which are Velcro tipped at 13 to engage with each other over the shoulder strap. At least one 14 of these pieces should incorporate a releasable locking device.
  • Figure 6 shows this locking device as comprised of an L- shaped camming lever 15 pivoted about a pin 16 in side retainers 17 of open construction.
  • the camming lever can be operated between a position where the member 1 is allowed to run along the shoulder strap and a position where the member 1 is cammed down against the shoulder strap, a suitable distance away from the bag-like body CS of the backpack Z to fit the user's anatomy.
  • the pieces 1 1 , 14 of these members 1 have their undersides lined with a soft yielding material 18 for more comfortable contact with the user's body (as basically favored by the shape of the pieces 1 1).
  • a positive engagement means (Figures 7 and 8) is arranged on the individual hinge-connected pieces for locking them in selected mutually angled positions, thereby to further a close fit of the attachment to a user's anatomy and/ or meet a user's preference.
  • locking devices are provided on one side of said pieces, according to the preferred embodiment of Figure 7, which devices comprise a small gear wheel 19 and a slider 20.
  • the gear wheel 19 locates next to one end of the side of the piece, 1 1 and/or 14, and the slider 20 is moved along this side.
  • the slider 20 is formed at one end with a jaw 21 for engagement with teeth of the gear wheel 19 on the adjacent piece, 11 or 14, and is biased away from the latter by a spring 11 mounted on the other end of the slider. After a desired included angle between two pieces 1 1 and/or 14 is found, the slider 20 of one piece is shifted against the bias of the spring 14 to engage the gear wheel 19 on the other piece, thereby locking both pieces together in their set positions. To maintain an angled relationship between the two pieces 11 and/or 14, the slider 20 is locked in the engaged position with the wheel 19 by driving a knurled end 25 of a tapered pin 23 through a mating hole in the slider 20.
  • a retainer 26 has a shank slidable along a slot 27 to hold the slider 20 close against the side of the piece 11.
  • FIG. 1 A backpack Z incorporating the inventive attachment and being carried by a girl B is shown in Figure 1 1.
  • the invention does achieve its object of better distributing the weight of a backpack across the user's shoulders, thereby correcting a prior tendency to assume a leaning attitude under the backpack weight that can harm young users in their growth period. Additionally, the inventive backpack attachment makes the backpack easier and more comfortable to use by that it can be carried more efficiently, even when loaded with contents that may be unusually heavy.
  • the attachment according to the present invention can also advantageously be used not only to prevent harm to young users by eliminating the tendency to assume a leaning attitude under the backpack weight, but also to correct already established forms of scoliosis, lordosis, kyphosis and other abnormal curvatures of the spine.
