Description

The invention relates to a backpack carrying container, comprising a receiving container with a rear side directed towards the wearer's back in the carrying position and two shoulder straps through which the arms pass through in the carrying position.

Such a backpack is usually designed as a backpack or as a school satchel. The container comprises the actual receiving container, which can have one or more compartments into which objects can be introduced. In order to be able to carry the backpack comfortably, two shoulder straps are provided, which extend quasi from the back and can be penetrated by the arms, so that the receptacle is positioned in a known manner on the back and is directed with its back to the back of the wearer . The receptacle itself can be made of a fabric or have a stabilizing base structure that is covered with fabric, but also with leather or the like. In order to increase wearing comfort, it is known to pad the back, for which purpose a larger-area padding layer is sewn into the back, which is firmly inserted into the material forming the receptacle or into the cover. As a result, the receptacle is padded towards the back, so that it is more comfortable to carry, especially since relatively heavy objects can also be transported.

The upholstery offers improved wearing comfort, but is not individually designed because it is the same for the entire model series.

The invention is therefore based on the problem of specifying a backpack container which is improved in comparison.

To solve this problem, it is provided according to the invention in a backpack container of the type mentioned at the outset that at least a reversibly openable and closable pocket with at least one removable cushion element is provided.

The backpack container according to the invention is characterized in that at least one pocket is provided on the rear side, in which a removable cushion element is arranged. This cushion element can be removed in a simple manner by opening the pocket, which offers a number of advantages. Because this gives the user the option of using an upholstery element that better meets his individual needs. For this purpose, the user is offered a number of different types of upholstery elements, which he can use as desired according to individual wishes, in order to adapt the backpack container so that it is optimally comfortable for him to carry. For this purpose, of course, the usable upholstery elements differ in terms of their shape or geometry, the material or the hardness, etc., which will be discussed below in order to offer a corresponding range of variation.

Another advantage is that the upholstery element can be cleaned in a simple manner. Since such a backpack is also often used during sporting activities in which one sweats, it sometimes happens that the upholstery element soaks up sweat or otherwise contaminates it. Here there is now the advantageous possibility of removing and washing the upholstery element if necessary and reinserting it in the cleaned state, which is beneficial for hygiene.

In order to be able to open and close the bag in a simple manner, it is advisable to provide a zipper which extends over a substantial part of the bag length or the entire bag length and which allows easy opening and closing. As an alternative to this, the use of one or more Velcro fasteners or snap fasteners is also conceivable.

As described, at least one pocket is provided on the rear. This can now extend in different directions and be positioned differently be. According to a first alternative of the invention, the pocket can extend transversely to the height of the receptacle and be arranged in a lower area of the rear side, which in the carrying position is in the area of the lumbar vertebrae. Here the pocket runs transversely in the lower rear area, that is to say almost horizontally in the carrying position. In the carrying position, it is located adjacent to the lumbar region and can therefore support and cushion the sometimes heavy receptacle towards the lumbar region. As a result, the seat of the receptacle on the back can be significantly improved, and the load can also be better cushioned and distributed.

As an alternative or in addition to this, it is conceivable that the pocket extends along the height of the receptacle and is arranged in a central area of the rear side, which is in the area of the spine in the carrying position. This quasi-vertical extension of the pocket offers the possibility of cushioning or supporting the receptacle in an optimized manner towards the spine via the at least one cushion element, so that the spine is relieved and there is less pressure on the vertebral bodies.

In this case, only one longitudinally extending pocket can be provided, which is located in the middle of the rear side, that is to say runs directly over the spine in the carrying position, as it were. The pocket is correspondingly wide and extends on both sides of the spine, so that the padding element also extends to both sides of the spine and the weight to be supported can be distributed and supported on the side of the spine, or two padding elements can be arranged next to one another.

Alternatively, it is conceivable to provide two longitudinally extending pockets which are arranged side by side and offset laterally to the center of the rear side. As a result, these two pockets hold the spine between them. A padding element can be inserted into each pocket, which supports and cushions the area adjacent to the spine, so that the spine can in turn be relieved.

It is conceivable to use only a single cushion element in the or each pocket, which almost completely fills the pocket. Alternatively, it is possible to arrange several cushion elements lying one on top of the other in the pocket, which are either not connected to one another or are fixedly or detachably connected to one another. For example, two or three thinner upholstery elements are placed on top of one another and virtually form a stack of elements. If the upholstery elements differ somewhat in their geometry or their mechanical properties, in particular their hardness, an individually configured "total upholstery element" can be formed, for example comprising a very soft upholstery and a significantly harder upholstery, so that the softer upholstery can be used for example The back points and gently cushions, while the harder padding provides basic stability or something similar. This means that the multiple cushion elements can differ in hardness and / or shape.

As described, it is possible that the cushion elements are not connected to one another, that is, that they lie loosely on top of one another. However, they can also be connected to one another in a detachable manner, for example via Velcro fasteners or the like, which allow easy assembly and disconnection. Alternatively, it is also conceivable that the upholstery elements are already firmly connected at the factory, resulting in a solid multi-layer structure.

Furthermore, it is conceivable that, when using several cushion elements lying one above the other, a first, softer cushion element is fixed in position in the pocket, while one or more further, harder cushion elements can be removed. As described, a soft cushion element cannot necessarily have a corresponding dimensional stability. The embodiment of the invention now provides for this softer, less dimensionally stable upholstery element to be firmly integrated on the pocket side, i.e. for example to be sewn firmly into the pocket material or pocket material, or to be fixed sufficiently firmly using Velcro fasteners, for example, and simply to insert the one or more additional upholstery elements into the pocket .

A particularly expedient development of the invention provides that the cushion element or at least one of the plurality of cushion elements lying one above the other is anatomically shaped to match the shape of the back area of the wearer on which the bag rests. According to this embodiment of the invention, a cushion element takes on the shape of the back area towards which it is intended to support, in order to ensure optimum wearing comfort on the one hand, but also protection of body parts on the other. It is therefore adapted to the given anatomy of the back area, which is advantageous for better load and pressure distribution and support.

In this context, it is conceivable that the anatomically shaped cushion element arranged in the transverse pocket has a transverse, convex curvature. The back shows a slight, concave curve in the area of the lumbar vertebrae. A rucksack or a school satchel or the like usually extends into this area and sits in this area, which is slightly curved outwards towards the buttocks. In order to make an anatomical adaptation of the upholstery element here, the upholstery element is provided with a convex curvature that accommodates the usual anatomical shape in this concave-shaped back area, so that there is shape compatibility and the upholstery element is adapted to shape and sits flat.

The longitudinal pocket or pockets are arranged in the area of the spine. In order to give an anatomically oriented shape here as well, a further development of the invention provides that the cushion elements arranged in the longitudinal pocket or pockets or at least one of the cushion elements arranged therein have a longitudinal channel or with an adjacent one Forms upholstery element. A canal is thus formed here which runs longitudinally in the middle, based on the width of the back, and which receives the spine or the spinous processes. Different configurations are conceivable here. If only one common, centrally arranged pocket is used, in which only one upholstery element or only one "total upholstery element" is used, This one padding element has a central, longitudinal channel, i.e. a corresponding recess, which accommodates the spine or the spinous processes, so that these are relieved after the padding element with the element sections adjoining the channel on both sides is present on both sides of the spine Muscles. If two pockets are used, a separate cushion element is accommodated in each pocket, so that a corresponding channel is inevitably formed between them, since the two cushion elements are not connected to one another. The then unloaded spinous processes lie in this intermediate area, while the cushioning elements are in turn supported towards the muscles.

An advantageous further development of the invention provides that the or at least one of the plurality of cushion elements lying one above the other has a ventilation structure. This ventilation structure enables ventilation in order to be able to dissipate heat, but also moisture, or to be able to ventilate or rear-ventilate the upholstery element, which further improves wearing comfort.

A plurality of holes or grooves or recesses that enable ventilation can be provided as such a ventilation structure. The holes, which extend, for example, to the rear, make it possible to transport air or moisture from the back to the rear and there, for example, to dissipate it to the side via a transverse groove structure or the like.

In order to be able to easily produce a cushion element with a correspondingly varying geometry or a geometry adapted to the anatomy, but also with appropriate softness or hardness or rigidity and possibly also with a corresponding ventilation structure, the or each cushion element is preferably formed from a foam. Such a foam element can be formed using a corresponding shape with any three-dimensional geometry, and ventilation structures such as holes, grooves or the like can also be formed without problems. Even the hardness can be varied almost at will, from very soft to relatively hard. This means that when foam is used as the upholstery element material, there is any very large range of variation with regard to the upholstery elements, which must also be provided in different sizes, especially for different backpack or school bag sizes (children, adults, different volumes of receptacles, etc.).

It is conceivable to produce a cushion element only from the actual element material, that is to say in particular the foam. It is useful if the or each cushion element also has a cover in addition to the actual element core, that is to say for example the foam core. This means that an additional cover is provided, which in turn can have specific properties and which is, for example, vapor-permeable in order to transport moisture away from the back, in particular if a corresponding ventilation structure is provided on the upholstery element. This cover is preferably a knitted fabric or a woven fabric and, like the upholstery element itself, can be washed without any problems. The coating is preferably arranged firmly on the element core, that is to say not detachable. Alternatively, it would also be conceivable, for example, to provide a zip fastener and to design the cover in the manner of a pocket, so that the element core can be changed and a cover can be reused.

It is also useful if the cushion element or the cover is water-repellent. This is advantageous in that, when the rucksack or the like is used in winter, it can prevent snow from being pressed through the cover, for example into the ventilation structure of the upholstery element, and clogging it. It is also conceivable, however, not to provide such a ventilation structure for a cushion element specifically intended for winter use, but nevertheless to make the cushion element or the cover correspondingly water-repellent and to use a different cushion element with a corresponding ventilation structure in summer.

As described, the backpack is preferably a rucksack or a school satchel, but its use is not limited to this.

Fig. 1 shows a backpack 1 here in the form of a rucksack 2 with a receptacle 3, which can usually be opened and closed via a cover section 4 that is pivotable.

In the area of the rear side 5 of the receptacle 3, two shoulder straps 6 are provided through which the arms reach in a known manner, so that the backpack 2 can be carried on the back.

On the rear side 5, a pocket 8 is arranged in the lower area 7 of the rear side 5 which is in the carrying position in the region of the lumbar vertebrae and which can be seen to extend transversely to the longitudinal direction of the rear side 5. The pocket 8 is used to hold a removable cushion element, via which the lower area 7 can be padded individually.

Fig. 2 shows an enlarged view of the pocket 8 as well as a removed cushion element 9 that can be inserted into the pocket 8. The pocket 8 is formed from a fabric or fabric 10 and is firmly sewn to the rear 5. The bag can be opened and closed reversibly via a zip fastener 11, it being possible for a Velcro fastener or the like to be provided instead of a zip fastener 11. The fabric 10 can, for example, be slightly perforated or moisture-permeable, so that moisture that can arise on the back of the wearer can, as it were, be let through and be conducted to the upholstery element 9, via which it can be carried on.

The cushion element 9 is also in Fig. 2 shown. It is preferably made from a foam. As a foam body, the upholstery element 9 is very easy to manufacture, and its mechanical properties, in particular, can be varied as desired. Because it can be used a foam material with different hardness, that is, that of the user for example, three or five different padding elements 9 of different degrees of hardness are made available, which he can insert into the pocket 8 as desired, so that he can individually adjust the degree of padding or the support.

In addition, in the exemplary embodiment shown, the upholstery element 9 is also shaped in accordance with the shape of the back part against which the upholstery element 9 or the pocket 8 rests. Since the pocket 8 and thus the cushion element 9 rests in the region of the lumbar spine, where the back has a slightly concave structure and merges into the buttocks, the cushion element 9 is provided with a bulge 12 for adapting its shape, which takes up the shape of the back. The upholstery element 9 is slightly compressed when it is worn and, due to the material distribution, adapts itself optimally to the shape of the back area, so that very good load distribution and support can be achieved in conjunction with good upholstery.

As Fig. 2 also shows, the cushion element 9 has a ventilation structure 13, which is formed here by a plurality of holes 14 that are distributed over the surface of the cushion element 9, and by grooves 15 formed on the rear. Moisture and heat diffusing through the fabric 10 is conducted via the holes 14 from the front to the rear, where it can be discharged to the side via the transverse grooves 15. This means that ventilation in the back area is possible through this and waterlogging or the like caused by sweating can at least partially be avoided.

Fig. 3 shows a partial view of the rucksack 2 with the rear side 5, shown here only in principle, on which the pocket 8, formed by the fabric 10, is formed. The upholstery element 9 with the ventilation structure in the form of the holes 14 and the rear grooves 15 is also shown cut away 10 is sufficiently elastic, i.e. somewhat elastic or flexible Fabric or knitted fabric, so that it can adapt to the shape of the cushion element 9 without problems.

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

It is conceivable that the two cushion elements 9a, 9b only lie loosely on top of one another. Alternatively, however, it is also possible to fix them to one another in a separable manner, for example by means of Velcro fasteners, although these Velcro fasteners are not shown in more detail here.

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

Here, too, a receptacle 3 is provided which can be opened and closed via a cover 4. The receptacle 3 has a rear side 5, and corresponding shoulder straps 6 are also provided which, for the sake of clarity, are shown here folded over towards the front side.

Here, too, a pocket 8 is provided, but this runs in the longitudinal direction of the rear side 5, that is to say extends from bottom to top. The pocket 8 is arranged in the middle area of the rear side 5 and extends to both sides, so that a correspondingly wide, but at the same time also high, cushion element can be inserted into the pocket 8 in a detachable and thus removable manner.

A zip fastener 11 is also provided here to open the pocket 8, which is again formed from a fabric 10.

Because the pocket is arranged centrally on the rear and extends over approximately half the height of the rear, it consequently extends over a considerable part of the spine in the carrying position, which makes it possible to use a cushion element that is anatomically adapted with respect to this back area. One such is exemplified in Fig. 6 shown. The upholstery element 9 shown there, which by way of example can be inserted into an optional covering 17, shown in dashed lines, made of a woven or knitted fabric, is in turn a foam element. If a casing 17 is provided, the foam element is accordingly the element core.

On the side facing the back of the wearer, a channel 18 is formed in the middle, that is, the surface 19 is deepened in the middle, so that there is a receiving space for the spinous processes of the spine. This is consequently relieved, the support takes place via the side areas 20 of the upholstery element 9, which is obviously designed to be slightly arched or curved in order to adapt to the anatomy of the back as best as possible.

A perspective view of the cushion element 9 from Fig. 6 is in Fig. 7 shown, from which the structure of the surface 19 can be seen. The central channel 18 is shown as well as the two side areas 20 of the foam padding element 9. Also shown here is a ventilation structure 13, which in turn is in the form of holes 14, which are designed here as transversely arranged, elongated slots that extend from front to back .

As described, the cushion element 9 consists of a foam which can be compressed to the extent that it can be inserted into the pocket 8. In this case it is to be pressed together a little so that it can be pushed through the central zip fastener 11. In the event that the zipper 11 were on the side, a correspondingly strong compressibility of the cushion element 9 is not absolutely necessary.

While the Figures 6 and 7th show a one-piece upholstery element 9, there is of course also the possibility here of forming this upholstery element from two layers lying one on top of the other, similar to that in relation to FIG Fig. 4 already described, whereby here too the two separate upholstery elements can differ in their hardness or the like, as well as of course in their geometry.

Fig. 8 shows an embodiment in which only one pocket 8 is again formed on the rear side 5 via a corresponding fabric 10, which in turn has a central zip fastener 11. Here two cushion elements 9 are arranged next to one another, which extend vertically and each virtually fill one half of the pocket. Both are geometrically identical and have a section which tapers towards the center, so that a channel 18 is again formed between them. Since here two separate padding elements 9 can be pushed into the central pocket 8, which has the central zip fastener 11, it is not necessary here for the padding elements 9 to be able to be compressed too much, since there is sufficient space available for insertion. Here, the padding elements 9 can be made correspondingly harder. However, these are also preferably corresponding foam elements.

Fig. 9 finally shows an embodiment in the form of a sectional partial view in which two pockets 8 are provided on the rear side 5, in each of which a cushion element 9 is received. The pockets 8, which can each be opened and closed via a zipper 11, are arranged offset to the longitudinal center of the rear side 5, so that the two cushion elements 9 are also centrally spaced from one another and a channel 18 is formed here as well, which the spinous processes the spine takes up. The upholstery elements 9 are mirror-inverted in their cross-sectional geometry. Basically there is the possibility of producing only one cushion element 9, which is inserted rotated by 180 ° in the other pocket.

Of course, there is also the option to contact the Figures 8 and 9 Ventilation structures 13 shown in the upholstery elements 9 should be provided in the form of holes 14 or grooves 15 etc. can be so that the respective upholstery element 9 (this also applies in relation to Fig. 6 ) can be removed separately and exchanged if necessary.
