Definitions

  • the invention relates to a safety school bag with an inserted stiffening part and an anatomically shaped back plate with breathable zones.
  • a school bag is known from DE-GM 76 19 523, which is provided with cat eye strips in order to draw attention to the pupil in road traffic and thus to increase its safety.
  • the satchel shown there does not make a significant contribution to increasing the safety of the pupil, rather the arrangements of cat eyes shown there bring additional injury possibilities with it.
  • a safety satchel according to the preamble, which is characterized in that to secure the upper edge of the stiffener partly a neck pad is attached to the back plate as well as additional pockets on the top, the back and the sides of the satchel, which absorb shock energy in the event of an accident as well as the correspondingly designed stiffening part and the back plate provided with cushions, that all fastening devices attached to the satchel, Hooks or buckles are defused by covers and that warning stripes and reflectors, possibly warning lights, are attached to the satchel in a clearly visible manner.
  • one of the additional pockets is designed as a color-coded first aid bag, and one of the additional pockets is designed as a loose, soft fabric pocket approximately the width of the satchel and fastened by means of the hooks on the back of the satchel so that they essentially extend from the top to the top bottom of the satchel is enough.
  • one of the additional pockets which is formed on the back of the satchel, begins below the reflectors, extends essentially to the lower end of the satchel, has essentially the same width as the satchel and carries at least one Warning stripes.
  • the additional pockets attached to the sides of the satchel preferably form a pocket over substantially the entire height and depth of the satchel.
  • two smaller pockets are formed one above the other, one of them of these smaller bags is a color-coded first aid bag.
  • the pockets can be securely closed with Velcro or zippers.
  • the satchel has transverse straps connected to its side walls on its upper side, which can be placed one on top of the other and fixed to one another by means of a Velcro fastener, so that they prevent the satchel from gaping apart.
  • This design of a back part ensures that the load is distributed over insensitive areas of the back and the carrier can still move relatively freely.
  • the recesses also ensure a certain amount of air circulation, so that there is no increased sweat, so there is formation.
  • the lower upholstery beads are preferably formed higher than the upper ones, so that both people with a hollow cross and those with a rounded back, of course also people with a normal physique, Even heavy loads can be borne for a long time due to the uniform introduction of the forces.
  • the back plate preferably has depressions which merge into the upper upholstery beads in such a way that the shoulder blades of the wearer remain largely free to move due to the resilience of the upholstery material.
  • the depressions are preferably worked into the cushion a little less deeply than is the case for the depressions for keeping the spine free. With a concave shape, the load can be held securely on the shoulder blades even when subjected to lateral loads.
  • the upholstery beads are also concave in shape and thus adapt to the transverse curvature of the back.
  • the upholstery together with the upholstery is made in one piece, but a layered construction can also bring advantages.
  • Foamed, elastic synthetic resins such as polyurethane foam, are suitable as upholstery material.
  • a foam-molded back part lends itself here, in which, if necessary, larger hollow acid can be omitted in order to save weight.
  • this padding is connected to a relatively rigid base plate, e.g. by gluing, welding or vulcanizing.
  • the cover 16 is in this case designed as a cloth strip attached at the top and open from below and protects both the user against injuries to the zipper and the contents of the pocket against moisture.
  • Such closure covers are equally provided on the side pockets 3, 4, 5, 6 and 7 (see Fig. 2).
  • These side pockets or the back pocket work when they are in the recommended Filled with softer objects, such as clothing, snacks, etc., than shock-absorbing pillows. Since the pocket openings are closed by the covers 16, the risk of getting caught and an accident caused thereby is also reduced.
  • One of the small side pockets is filled with bandages, plasters and a hemostatic bandage, i.e. a first aid kit, and contrasted in color with the rest of the satchel, for example.
  • a student ID card with personal data such as place of residence, blood group etc. can be provided both in this side pocket 6 and in a transparent address pocket 31 attached to the large side pocket 3.
  • the clothing pocket 7 shown in FIG. 2 is fastened to the satchel in a fixed or removable manner and forms a further protective cushion in the event of an impact on the back.
  • This pocket 7 e.g.
  • the carabiner hooks 21 are fastened to the satchel via carabiner hooks and, when not in use, are stowed in fabric pouches 22 which are firmly attached to the satchel cover. In this way, similar to pocket closures 15, sticking or direct injury is reliably avoided.
  • FIGS. 3a and 3b A preferred embodiment of the back cushion of the safety school bag is shown in FIGS. 3a and 3b.
  • the satchel lies with the pads 8 on the shoulder blades, with the pads 9, depending on the size of the wearer, on the pelvis.
  • the four cushions are separated from one another by a horizontal 10 or vertical breathing zone 11. In this way, the satchel does not become a nuisance even when worn for a long time, and even undisciplined students do not throw it around by the hand instead of carrying it on their back.
  • the vertical breathing zone 11 in particular has a cushion 24 which serves to protect the spine.
  • the back plate 30 of the satchel preferably consists of a correspondingly shaped, somewhat harder material, such as plastic or cardboard, the cushions 8, 9 and 24 evenly distribute any impact pressure that may occur onto the bone structure and thus avoid selective overstressing.
  • a shape or upholstery of a back plate can prevent postural damage in children, possibly even correct it.
  • the sides of the satchel are over cuer tabs 23, e.g. can be attached to each other by means of a Velcro fastener, pulled together and the bag contents thereby covered again.
  • These brackets 23 also act, for example in the event of an impact obliquely from behind, as “friction dampers” and thus destroy kinetic energy.
  • FIG. 5 shows the construction of the back cushion again.
  • the shoulder straps 12 are fastened to the bottom of the satchel by means of buckles 26.
  • buckles 26 Such buckles have proven to be the only practicable solution of an adjustable belt buckle, since the different types of buckles known up to now either open by themselves or cannot be handled by children.
  • the mandrels of such buckles represent a certain risk of injury, so that cover tabs 25 are provided in the embodiment shown here. These consist of a piece of hose that ends in a tab and are pushed onto the shoulder straps 12. If the buckle 26 is closed, the tab of the cover 25 can be pushed through the buckle and thus safely covers the mandrel of the buckle 26. An injury to this buckle is therefore almost completely impossible.
  • the satchel On the underside, the satchel has feet 27 for vertical placement.
  • the stiffening part 29 which is inserted into the interior of the satchel.
  • the stiffening part is preferably made of plastic and has a rear side which faces the carrier, two side parts fastened to it in a tiltable manner and an equally fastened base part.
  • the stiffening part 29 is inserted into the satchel, which is preferably made of plastic material, and fastened to it by means of push buttons 28.
  • the stiffening part thus spans the otherwise soft satchel in the unfilled state. In contrast to the state of the Technology, however, this stiffening part folds in the event of an impact, the side walls may buckle and thus convert kinetic into thermal energy or deformation energy.
  • the foldability of the stiffening part is also a further advantage if the satchel is to be stowed away, for example during the holidays, or during shipping or sales.
  • the satchel is preferably made in a clearly visible color and additionally has strips 17 which are coated with fluorescent colors. These light strips are attached to both the sides and the back of the satchel.
  • the back part has a padding 106 which is fastened on a base plate 107.
  • Bulb-shaped elevations 103, 103a, 104 and 104a are worked out of the padding 106.
  • the lower upholstery beads begin at the lower edge of the upholstery 106 and form two approximately rectangular strips, while the upper beads 103 and 103a rise as hook-shaped elevations from the upper edge of the upholstery 6 inwards and again tapering to the side edge.
  • the upholstery is symmetrical to the longitudinal axis, the longitudinal axis having to be thought through the middle of the depression 101.
  • the upper upholstery beads 103 and 103a merge from the inside to the outside or from the bottom upward into depressions 105 and 105a which are arranged at the upper corners of the upholstery 106.
  • FIG. 8 shows where the support zones of the back part are located relative to the body of the wearer.
  • this figure shows how the schoolbag 108 is advantageously arranged on the back part (dash-dotted line).
  • the upper padding beads 103 and 103a result in contact surfaces of the back part, which are designated by 113 and 113a
  • the lower padding beads 104 and 104a are those which are designated by 114 and 114a. From this representation it can be seen that the shoulder blades 111 and 111a of the wearer are enclosed by the upper cushion beads 103 and 103a on their inside and underside, while the lower cushion beads 104 and 104a come to rest in the area of the sacrum next to the spine. In any case, the spine 112 remains excluded.
  • FIG. 13 A more precise representation of the profiles of the back plate shown here is shown in FIG. 13.
  • the horizontal sections 13.1 to 13.4 are plotted on the left, the vertical sections 13.5 to 13.7 in the right half.
  • the horizontal section 13.1 which is set approximately at the level of the shoulder blades 111, has a strong elevation in the region of the bead 103, which comes to rest between the shoulder blade 111 and the spine 112.
  • the shoulder blades 111 lie under the depressions 115, so that they remain relatively free to move.
  • the horizontal section 13.2 applied under the shoulder blades 111 shows the slightly concavely curved upper bead 103, which has a deeper recess 101 only in the region of the spine.
  • the area of the horizontal recess 102 is shown in section 13.3, from which it can be seen that the back plate, viewed horizontally, runs approximately straight in this zone.
  • the horizontal section 13.4 is made in the area of the lower cushions 104, which are slightly raised in the outer area and fall in the direction of the central depression 101, so that a concave cavity is formed to secure the lateral hold.
  • the vertical section 13.5 which is set approximately at the level of the shoulder blade center, shows the depression 105a which runs uniformly on the outside in the vertical direction and merges downwards into the upper bead 103a.
  • the bead 103a is separated from the lower bead 104a by the horizontal depression 102, the surfaces of the two beads can be connected in the vertical direction by an imaginary line, the upper pad 103a being thinner than the lower pad 104a.
  • the vertical section 13.6 is applied in the area between the spine 112 and the shoulder blade 111 shows, viewed from top to bottom, the increasing thickness of the pads 103a and 104a, which are separated from one another by the horizontal depression 102.
  • the area of constant depth of the depression 101 is shown in section 13.7.
  • the recesses 109 are advantageously distributed in a uniform pattern over the entire back plate in order to achieve uniform cushioning.
  • the depth of the recesses 109 corresponds to the thickness of the upholstery, so that material of approximately constant thickness remains between the recesses 109 and the surface of the upholstery 106, as is shown in the sectional drawing in FIG. 15.
  • the recesses 109 can of course also be distributed in other patterns, so that e.g. result in stiffer and less rigid zones of upholstery.
