[0001] The invention relates to a backpack carrying container comprising a receptacle with a rear side directed towards the back of the wearer in the carrying position and two shoulder straps through which the arms can pass in the carrying position.

[0005] US 9,072,365 B1 discloses a cushion for a backpack carrying container.

[0006] Such a backpack is usually designed as a backpack or school bag. The container comprises the actual receptacle, which can have one or more compartments into which objects can be placed. To ensure comfortable carrying, two shoulder straps are provided that extend from the back and can be grasped by the arms, so that the receptacle is positioned on the back in the usual way, with its back facing the wearer's back. The receptacle itself can be made of a fabric or have a stabilizing base structure covered with fabric, but also with leather or similar. To increase wearing comfort, it is known to pad the back. For this purpose, a large padding layer is sewn into the back, i.e., firmly inserted into the fabric or cover forming the receptacle.This cushions the container towards the back, making it more comfortable to carry, especially since it can also transport relatively heavy objects.

[0007] The padding offers improved comfort, but is not very individually designed, as it is the same for the entire model range.

[0008] The invention is therefore based on the problem of providing a backpack carrying container that is improved compared to the above.

[0009] The invention solves the problem by the features of claim 1.

[0010] The backpack carrying case according to the invention is characterized in that at least one pocket is provided on the back, in which a removable cushioning element is arranged. This cushioning element can be easily removed by opening the pocket, which offers a number of advantages. This is because it gives the user the option of inserting a cushioning element that better meets their individual needs. For this purpose, the user is offered a variety of different cushioning elements, which they can use as desired according to their individual needs in order to adapt the backpack carrying case so that it offers optimal carrying comfort. For this purpose, the cushioning elements that can be used naturally differ in terms of their shape or geometry, material or hardness, etc., which will be discussed below in order to offer a corresponding range of variations.

[0011] Another advantage is that the padded element is easy to clean. Since this type of backpack is often used for sporting activities that involve sweating, it can sometimes happen that the padded element absorbs sweat or becomes otherwise soiled. This makes it advantageous to be able to remove and wash the padded element as needed, and then reinsert it in a clean state, which promotes hygiene.

[0012] To make opening and closing the bag easy, it's best to include a zipper that extends across a significant portion or the entire length of the bag, allowing for easy opening and closing. Alternatively, one or more hook-and-loop fasteners or snap fasteners are also conceivable.

[0013] The bag contains several stacked padding elements, which are either connected to each other, fixedly, or detachably. For example, two or three thinner padding elements are placed on top of each other, forming a kind of stack of elements. If the padding elements differ slightly in their geometry or mechanical properties, particularly their hardness, they can be combined to create an individually configured "total padding element," for example, comprising a very soft padding and a significantly harder padding. The softer padding, for example, faces the back and provides gentle cushioning, while the harder padding provides basic stability, or something similar. This means that the multiple padding elements can differ in hardness and / or shape.

[0014] As described, it is possible for the upholstery elements to be unconnected, meaning they rest loosely on top of each other. However, they can also be detachably connected, for example, via Velcro fasteners or similar, allowing for easy assembly and disassembly. Alternatively, it is also conceivable for the upholstery elements to be firmly connected at the factory, resulting in a solid multi-layer structure.

[0015] Furthermore, it is conceivable that, when using several padding elements stacked on top of each other, a first, softer padding element is fixed in position within the bag, while one or more additional, harder padding elements are removable. As described, a soft padding element cannot necessarily have the corresponding dimensional stability. The invention now provides for this softer, less dimensionally stable padding element to be firmly integrated into the bag, for example, by firmly sewing it into the bag material or fabric, or by sufficiently securing it using hook-and-loop fasteners, and for the one or more additional padding elements to be simply inserted into the bag.

[0016] As described, at least one pocket is provided on the back. This can extend in different directions and be positioned differently. According to a first alternative invention, the pocket can extend transversely to the height of the storage container and be arranged in a lower area of ​​the back, which in the carrying position lies in the region of the lumbar vertebrae. Here, the pocket runs transversely in the lower back area, i.e., more or less horizontally in the carrying position. In the carrying position, it is located adjacent to the lumbar vertebrae area and can therefore support and cushion the sometimes heavy storage container towards the lumbar vertebrae area. This can significantly improve the fit of the storage container on the back, and also better cushion and distribute the load.

[0017] Alternatively or additionally, it is conceivable for the pocket to extend the entire height of the storage container and be located in a central area of ​​the back, which, when in the carrying position, is in the region of the spine. This quasi-vertical pocket extension offers the possibility of optimally cushioning or supporting the storage container towards the spine via at least one padding element, thus relieving strain on the spine and reducing pressure on the vertebral bodies.

[0018] This can be done with just one longitudinal pocket, located in the middle of the back, essentially running directly above the spine in the carrying position. The pocket is appropriately wide and extends to both sides of the spine, allowing the padding element to extend to both sides of the spine and distribute and support the weight to be supported along the sides of the spine. Alternatively, two padding elements can be arranged side by side.

[0019] Alternatively, it is conceivable to provide two longitudinally extending pockets, arranged side by side and offset laterally toward the center of the back. These two pockets thus accommodate the spine between them. A padding element can be inserted into each pocket, providing support and cushioning in the area adjacent to the spine, thus relieving pressure on the spine.

[0020] A particularly useful development of the invention provides that at least one of the several stacked padding elements is anatomically shaped to match the shape of the wearer's back against which the bag rests. According to this embodiment of the invention, a padding element takes on the shape of the back area it is intended to support, ensuring optimal comfort while also protecting certain body parts. Thus, an adaptation to the given anatomy of the back area is achieved, which is advantageous for better load and pressure distribution and support.

[0021] In this context, it is conceivable for the anatomically shaped padding element arranged in the transverse pocket to have a transverse, convex curvature. The back exhibits a slight, concave curvature in the lumbar region. A backpack, satchel, or similar item typically extends into this area and rests in this region, which, transitioning to the buttocks, is slightly curved outwards. To achieve an anatomical adaptation of the padding element, the padding element is provided with a convex curvature that takes up the usual anatomical shape in this concavely shaped back area, resulting in shape compatibility and the padding element sitting flat and conforming to the shape.

[0022] The longitudinal pocket(s) are arranged in the region of the spine. To ensure an anatomically oriented shape here as well, a further development of the invention provides that the padding element(s) arranged in the longitudinal pocket(s), or at least one of the padding elements arranged therein, has a longitudinal channel or forms one with an adjacent padding element. Thus, a channel is formed that runs longitudinally centrally, relative to the width of the back, and that accommodates the spinal column or spinous processes. Various configurations are conceivable.If only one centrally located pocket is used, into which only one padding element or only one "complete padding element" is inserted, this single padding element has a central, longitudinal channel, i.e., a corresponding recess, which accommodates the spinal column or spinous processes, thus relieving pressure on them after the padding element, with the element sections adjoining the channel on either side, rests on the muscles present on both sides of the spine. If two pockets are used, a separate padding element is accommodated in each pocket, so that a corresponding channel is inevitably formed between them, since the two padding elements are not connected to each other. The spinous processes, which are then unloaded, lie in this intermediate area, while the padding elements, in turn, are supported against the muscles.

[0023] An advantageous development of the invention provides that the or at least one of the several stacked padding elements has a ventilation structure. This ventilation structure enables ventilation to dissipate heat and moisture, or to ventilate the padding element or the rear of the padding element, which further improves wearing comfort.

[0024] Such a ventilation structure can consist of several holes, grooves, or recesses that allow for ventilation. The holes, which extend toward the back, for example, allow air or moisture to be transported from the back to the back and then discharged to the sides, for example, via a transverse groove structure or something similar.

[0025] In order to be able to easily produce a padding element with a correspondingly varying geometry adapted to the anatomy, but also with appropriate softness, hardness, or stiffness, and optionally also with an appropriate ventilation structure, the or each padding element is preferably made of foam. Such a foam element can be formed with any three-dimensional geometry using an appropriate mold; the formation of ventilation structures such as holes, grooves, or the like is also easily possible. The hardness can also be varied almost arbitrarily, from very soft to relatively hard. This means that when foam is used as the padding element material, a very wide range of variations is possible with regard to the padding elements, which is also particularly suitable for different backpack or school bag sizes (children's, adults, different volumes of the containers, etc.).) must be provided in different sizes.

[0026] It is conceivable to manufacture an upholstery element only from the actual element material, in particular the foam. It is expedient if the or each upholstery element also has a cover in addition to the actual element core, for example the foam core. This means that an additional cover is provided, which in turn can have specific properties and is, for example, vapor-permeable to transport moisture away from the back, particularly if a corresponding ventilation structure is provided on the upholstery element. This cover is preferably a knitted or woven fabric and, like the upholstery element itself, can be easily washed. Preferably, the cover is permanently attached to the element core and is therefore not removable.Alternatively, it would also be conceivable to provide a zipper and to design the cover in a pocket-like manner, so that the element core can be changed and a cover can be reused.

[0027] It is also advisable for the padding element or cover to be water-repellent. This is advantageous in that, when the backpack or similar item is used in winter, it prevents snow from being pushed through the cover, for example, into the padding element's ventilation structure and clogging it. However, it is also conceivable to not provide such a ventilation structure for a padding element specifically intended for winter use, but to nevertheless design the padding element or cover to be water-repellent, and to use a different padding element with a corresponding ventilation structure in summer.

[0028] As described, the backpack is preferably a backpack or a school bag, although its use is not limited to these.

[0029] Further advantages and details of the present invention will become apparent from the exemplary embodiments described below and from the drawings. In the drawings: Fig. 1 a perspective view of a backpack-shaped carrying container, Fig. 2 an enlarged partial view of a pocket extending transversely to the longitudinal direction of the back with the cushioning element removed, Fig. 3 a partial view, cut through the area of ​​the pocket from Fig. 2 , Fig. 4 a representation of a two-part cushioning element for the bag made of Fig. 2, Fig. 5 a rear view of a backpack container of a second embodiment with a pocket extending along the rear side, Fig. 6 a sectional view through a cushioning element to be inserted into the pocket, Fig. 7 a perspective view of the cushioning element from Fig. 6 , Fig. 8 a partial view, sectioned, through which the container from Fig. 5 in the area of ​​the pocket with two inserted padding elements, and Fig. 9 a partial view, cut through a container with two rear pockets and separate padding elements.

[0030] Fig. 1 shows a backpack container 1 here in the form of a backpack 2 with a receiving container 3, which can usually be opened and closed via a cover section 4, which is pivotable.

[0031] In the area of ​​the back 5 of the receptacle 3, two shoulder straps 6 are provided, through which the arms can be grasped in a known manner, so that the backpack 2 can be carried on the back.

[0032] On the back 5, in the lower area 7 of the back 5, which lies in the region of the lumbar vertebrae in the carrying position, a pocket 8 is arranged, which extends transversely to the longitudinal direction of the back 5. The pocket 8 serves to accommodate a removable padding element, via which the lower area 7 can be individually padded.

[0033] Fig. 2shows an enlarged view of the pocket 8 and a removed padding element 9 that can be inserted into the pocket 8. The pocket 8 is made of a fabric or woven material 10 and is firmly sewn to the back 5. The pocket can be reversibly opened and closed via a zipper 11, whereby a Velcro fastener or similar can also be provided instead of a zipper 11. The fabric 10 can, for example, be slightly perforated or moisture-permeable, so that moisture that may develop on the wearer's back can be essentially passed through and guided to the padding element 9, where it can be further transported.

[0034] The upholstery element 9 is also in Fig. 2shown. It is preferably made of a foam material. As a foam body, the cushioning element 9 is very easy to manufacture, and its mechanical properties, in particular, can be varied as desired. This is because a foam material with different degrees of hardness can be used, meaning that the user is provided with, for example, three or five different cushioning elements 9 of varying degrees of hardness, which they can insert into the pocket 8 as desired, allowing them to individually adjust the degree of cushioning or support.

[0035] Furthermore, in the illustrated embodiment, the cushioning element 9 is also shaped to match the shape of the back area against which the cushioning element 9 or the pocket 8 rests. Since the pocket 8 and thus the cushioning element 9 rests in the area of ​​the lumbar spine, where the back has a slightly concave structure and merges into the buttocks, the cushioning element 9 is provided with a curvature 12 to adapt to the shape of the back. The cushioning element 9 is slightly compressed when worn and, thanks to the material distribution, adapts perfectly to the shape of the back area, thus achieving very good load distribution and support in conjunction with good padding.

[0036] How Fig. 2As further shown, the cushioning element 9 has a ventilation structure 13, which here is formed by a plurality of holes 14 distributed over the surface of the cushioning element 9, as well as by grooves 15 formed on the back. Moisture and heat diffusing through the fabric 10 are guided via the holes 14 from the front to the back, where they can be dissipated to the side via the transverse grooves 15. This means that rear ventilation or ventilation in the back area is possible, and waterlogging caused by sweating or the like can be at least partially avoided.

[0037] Fig. 3shows a partial view of the backpack 2 with the rear side 5, shown here only in principle, on which the pocket 8 is formed, formed over the fabric 10. Also shown in section is the padding element 9 with the ventilation structure in the form of the holes 14 and the rear grooves 15. It can be seen that the shape of the fabric 10, or rather the pocket shape, approximately corresponds to the shape of the padding element 9, but this is not necessarily the case, namely when the fabric 10 is sufficiently elastic, i.e., a somewhat elastic or flexible woven or knitted fabric, so that it can adapt to the shape of the padding element 9 without problems.

[0038] Fig. 4 shows a further embodiment comprising two cushioning elements 9a, 9b, which are placed on top of each other and together form a "total cushioning element". The cushioning element 9a corresponds, for example, in its geometry to the cushioning element 9 of the Figures 2 and 3, thus also has a corresponding curvature 12, so that it is approximately adapted to the anatomical shape of the back area. This padding element 9a is placed on the rear padding element 9b, and both are inserted together into the pocket 8. The padding element 9b can be made of a harder material, i.e., a harder foam, than the padding element 9a. In this case, the padding element 9b has a stiffening function so that the "overall padding element" has sufficient stability or rigidity, while still being correspondingly soft in its front area, facing the back. The padding element 9b does not necessarily have to be made of foam; it can also be another, non-foamed plastic that has a certain degree of flexibility but is significantly harder than the foam padding element 9a.Depending on the combination of the padding elements 9a, 9b, which are each available in different degrees of hardness, for example, an "overall padding element" can be assembled which has an individual mechanical property, i.e. flexibility for the padding on the one hand, and stability on the other.

[0039] It is conceivable that the two cushioning elements 9a, 9b rest only loosely on top of one another. Alternatively, it is also possible to attach them separably to one another, for example, using hook-and-loop fasteners, although these hook-and-loop fasteners are not shown in detail here.

[0040] Fig. 5 shows a second embodiment of a backpack container 1 according to the invention, here in the form of a school bag 16. The same reference numerals are used for the same components.

[0041] Here, too, a receptacle 3 is provided, which can be opened and closed via a lid 4. The receptacle 3 has a rear side 5, as well as corresponding shoulder straps 6, which are shown folded over to the front for clarity.

[0042] A pocket 8 is also provided here, but this one runs in the longitudinal direction of the back 5, i.e., extends from bottom to top. The pocket 8 is located in the central area of ​​the back 5 and extends to both sides, allowing a correspondingly wide, yet tall, cushioning element to be detachably and thus removablely inserted into the pocket 8.

[0043] A zipper 11 is also provided here to open the pocket 8, which is again made of a fabric 10.

[0044] Because the pocket is positioned centrally at the back and extends over approximately half the height of the back, it extends over a considerable part of the spine when in the carrying position, which allows the use of a padding element that is anatomically adapted to this area of ​​the back. An example of this is shown in Fig. 6 The cushioning element 9 shown there, which can be inserted into an optional covering 17 made of a woven or knitted fabric (shown in dashed lines), is in turn a foam element. If a covering 17 is provided, the foam element is the element core.

[0045] On the side facing the wearer's back, a channel 18 is formed in the center, meaning that the surface 19 is recessed in the center, creating a space for the spinous processes of the spine. This relieves pressure on the spine, and support is provided by the side areas 20 of the cushion element 9, which is visibly slightly curved or curved to best adapt to the anatomy of the back.

[0046] A perspective view of the upholstery element 9 from Fig. 6 is in Fig. 7 , from which the structure of the surface 19 is evident. Shown are the central channel 18 as well as the two side regions 20 of the foam cushioning element 9. Also shown here is a ventilation structure 13, which is again designed in the form of holes 14, which here are designed as transversely arranged, elongated slots extending from front to back.

[0047] As described, the padding element 9 consists of a foam that can be compressed to the extent that it can be inserted into the pocket 8. In this case, it must be compressed slightly so that it can be pushed through the central zipper 11. In the event that the zipper 11 were on the side, a correspondingly strong compressibility of the padding element 9 is not absolutely necessary.

[0048] While the Figures 6 and 7 a one-piece cushion element 9, it is of course also possible to form this cushion element from two superimposed layers, similar to the case with regard to Fig. 4 already described, whereby here too the two separate cushioning elements can differ in their hardness or similar, as well as, of course, in their geometry.

[0049] Fig. 8shows a design in which only one pocket 8 is formed on the back 5 using a corresponding fabric 10, which in turn has a central zipper 11. Here, two padding elements 9 are arranged next to one another, which extend vertically and essentially each fill one half of the pocket. Both are geometrically identical and have a section that tapers towards the middle, so that a channel 18 is formed between them. Since two separate padding elements 9 can be inserted into the central pocket 8, which has the central zipper 11, it is not necessary for the padding elements 9 to be compressed too much, since there is sufficient space available for insertion. Here, the padding elements 9 can therefore be made correspondingly harder. However, these are also preferably corresponding foam elements.

[0050] Fig. 9finally shows an embodiment in the form of a sectional partial view, in which two pockets 8 are provided on the back 5, each of which accommodates a padding element 9. The pockets 8, which can each be opened and closed via a zipper 11, are arranged offset from the longitudinal center of the back 5, so that the two padding elements 9 are also spaced apart from one another in the middle, thus forming a channel 18 here too, which accommodates the spinous processes of the spine. The padding elements 9 are mirror-inverted in their cross-sectional geometry. In principle, it is possible to produce only one padding element 9, which is inserted into the other pocket rotated by 180°.

[0051] Of course, there is also the possibility to participate in the Figures 8 and 9shown cushion elements 9 to provide corresponding ventilation structures 13 in the form of holes 14 or grooves 15 etc. It is also possible to equip the cushion elements 9 with a covering 17, for example an elastic fabric or knitted fabric, in which they are firmly held, or which can also be opened if necessary, so that the respective cushion element 9 (this also applies with regard to Fig. 6 ) can be removed separately and exchanged if necessary.
