The invention relates to a carrying case, especially a backpack.

Particularly in sporting activities have tote bags, such as backpacks, the disadvantage that, for example, when moving the shoulders and the backpack itself or a storage container of the pack, are stored in the transportable items, is moved. This is the comfort, for example, in sports such as: mountain biking or rock climbing, serious.

From DE 201 11 889 a backpack with a support means in the form of two shoulder straps is known, wherein in each shoulder portion a is provided, which has a greater elasticity. By the provision of such elastic regions is to be achieved, that the backpack can be worn by different people, without having to adjust the carrying system to the appropriate person. Furthermore is achieved thereby a suspension of the backpack and thus cushioned power transmission. Larger and faster movements, such as those encountered in mountain biking or climbing are transmitted despite the provision of the elastic portion on the backpack so that the backpack is thereby moved and the wearing comfort remains severely impaired. Object of the invention is to improve comfort in tote bags, especially backpacks.

The problem is solved according to the invention through the features of claim 1 and 14 respectively.

The carrying case has a receptacle for receiving transported objects. The receptacle has a support means, such as one or more shoulder straps or shoulder strap, connected. To improve the comfort of backpacks and the like. Deteriorating property is movement decoupled from the receptacle in the carrying case of the invention the support means. This means that upon movement of the body, for example the shoulder, or a turning of the upper body, the receptacle of the carrier bag according to the invention is not or only slightly moved. For example, when mountain biking or climbing the upper body can be moved freely at least in certain areas, without the receiving container is moved. Thereby, the wearing comfort is greatly improved.

To improve the wearing comfort, the bag according to the invention comprises a receptacle connected to a support means, said support means includes upper and lower connecting elements, which may for example be connected with shoulder straps. Also, a shoulder to jointly form an upper and a lower connecting member serving. According to the invention, the

Connection elements in order to allow movement decoupling, tension elements on. The pulling elements, which are preferably being cables are slidably held on the receptacle. Further, a common pull element is provided at least between two connecting elements. Moving the body, which automatically Moving a connecting element leads, thus also causes a movement of a tension element. The movement of the tension element is transmitted due to the connection to a second connecting element on this. The spacing of the two connecting elements therefore remains constant at least substantially. The invention is thus based on the realization that the movement of a body part, such as lifting a shoulder, usually the motion of another body part in a relation to the carrying case has another direction to follow. This means that, for example, the distance between the carrying bag and a shoulder strap on the one side is shortened while being extended on the other side. It follows that the corresponding motion is not transmitted due to the provision of tension elements on the receptacle and thus the receiving container is decoupled from movement of the support means.

It is particularly preferred to provide a single common pull element is. The upper and lower connecting elements are thus connected by a single pulling element each other or formed as a single tension member. The tension thus extends, for example, between the shoulder straps and the receptacle. Here, the comfort can be further improved if the common pull element is self-contained. The common tension member thus extends, for example, of a connecting element or a shoulder in the region of the back to the receiving container, is held displaceably on the receiving container and runs in the region of the hips forward to the second shoulder. From this, the tension element then runs, in turn, back to the receptacle to which it is slidably supported and is from the receiving container towards the front for the first shoulder recycled. In particular, the pulling element on the shoulder straps is also slidably supported. A particular advantage of the inventive decoupling movement between the receptacle and the support means is that especially when wearing larger weights and / or during strenuous sports fatigue is reduced. Further may be achieved by movement of decoupling according to the invention a better weight distribution.

In a preferred embodiment, the two lower links, that is, those formed connecting elements, which are connected for example to the front or lower ends of the shoulder belts or the like. By a common tensioning element. The tension member, which is in particular designed as a cable is thus firmly connected, in this embodiment with the one front end of the shoulder belt, then preferably guided through a channel or a guide member on the receiving container and then connected to the front or lower end of the second shoulder belt. On the traction element the movement of the two lower ends of the shoulder straps is coupled. Thereby causes a pulling on one end of the cable, ie increasing the distance of the front end of the shoulder belt to the receiving container at the same time decreasing the distance of the front end of the other shoulder belt to the receiving container. In such an arrangement of a common tension member is a technically simple solution for realizing the motion decoupling between support means and receptacle. Elaborate winder for a traction element standing under tension, and the like. Are not required. Further, this embodiment has the major advantage that the movement decoupling is independent of the weight of the receptacle, which can vary greatly depending on the transported objects. In purely elastic fasteners movement decoupling is realized only within certain weight limits. If necessary, the tension element may additionally or parts thereof have a certain elasticity. In a further preferred embodiment, upper connecting elements are provided, which are preferably connected to rear ends of the shoulder straps, that is, with arranged on the back of the user's ends of the shoulder straps. These connecting elements are preferably formed elastically in the first embodiment. The upper connecting elements can, instead of the lower connecting elements, or preferably be provided in addition to these.

In a preferred embodiment of the invention the upper connecting elements these are connected via an intermediate element to the receiving container, so that the upper connecting elements are formed together with the intermediate element is Y-shaped.

To realize a motion decoupling in this area, it is possible according to another embodiment to connect the upper connecting elements in addition to or instead of their elastic configuration of a rotary member with the receptacle. Preferably in that case the rotary member is then connected by a single intermediate element centrally to the receptacle. A reciprocating of the user's upper body is thus deflected by the rotary member and does not lead for moving the receiving container so that the comfort is improved by providing the rotating member.

It is also possible to combine two or more bags on rotary elements with each other. The individual bags can be rotated thus against each other so that a relative movement between the pockets, like chain links or the like., Is possible. This likewise realized that, for a movement of the user, the pockets of the body, in particular the bags, are not or only slightly moved, so that the comfort is improved. In a particularly preferred embodiment of the upper connection elements, these likewise have a common tension element, which may be optionally additionally formed elastically. This common pull element is preferably connected to the two rear ends of the shoulder straps. Preferably, the common pull element is guided via a deflection element for guiding the common tension member. The deflection element may then preferably be connected preferably centrally through a single intermediate element to the receiving container. In this case the intermediate element is particularly preferably in a distance from an inner side, that is, a back support surface of the receiving container, connected thereto. This has the advantage that the upper connecting elements may not abut together with the rotary member, the common cable and / or the deflecting element at the back of the user, so that the comfort is further enhanced, and the rubbing of these elements on the back as well as sweating under is these elements avoided.

Both the provision of a common tension member at the lower connecting elements as well as the upper connecting elements may be such that the tension element between the two respective connecting elements and the channel or the guide element is provided on the bag. Likewise, the arrangement can be carried out vice versa, so that a rope or the like. Is provided on the bag and between two connecting elements, a common channel or a common guide element is arranged. Relevant is the possible relative movement between the channel or guide member and a tension member. It is also possible to arrange the tension elements or channels cross over, so that in each case a lower connecting element is connected to an upper connecting element. The tension elements it may be solid cables, cords, tapes, chains and the like.. It is also possible that a common cable includes an intermediate member, such as a load between the belt or the like.. The guide of the cable and the like. Either in a channel which may be formed as a closed channel corresponding to a tube or the like., Or in an open or partly open channel. Likewise, other guide elements, such as loops or eyelets, be provided.

In a further preferred embodiment, the upper tension member is not connected to the shoulder or the shoulder pad, but with the lower rope. The tension is thus slidably supported on the shoulder strap. To this end, with the shoulder or the shoulder pad, a channel, eyelets or the like. Connected by the pulling member is passed. This preferred embodiment of the carrying case of the invention, a further decoupling between receptacle and carrying device is realized. By this further slippage of the shoulder straps and shoulder pads is avoided on the shoulder by movements of the user. The wearing comfort is thus further improved.

It is particularly preferred that the lower and upper tension member are formed as a single common pull element is. In a further embodiment of the provident described is then a self-contained tension element. This preferably extends from a shoulder region down to the waist, is then through connected to the receptacle duct at approximately waist height guided from one to the other side of the hip, then runs from the hip back up to the other shoulder, and from there a U-shape the problem associated with the receiving container to the first deflecting shoulder. The cable thus has substantially the shape of a "double U".

In a further preferred embodiment is also a single, self-contained tension element such as a cable provided with which the receptacle is movably connected. A fundamental principle both preferred embodiments, therefore, is that a self-contained, portable connected to the receptacle or on the receptacle slidably held tension element is provided.

In a further preferred embodiment, the tension element preferably extends from one shoulder downwards to the hip, ie on the front of the body, there is shown by a provided on the receptacle channel or the like. Out and then extends in the back area of ​​the one waist obliquely upward to the other shoulder. Of this shoulder, the tension element extends downwardly to the other hip, in turn, is connected by a channel to the receiving container or the like., And then at the back obliquely upward to the first shoulder performed. The tension thus intersects in this embodiment in the back area. In this particularly preferred embodiment, a complete decoupling movement of the receiving container is realized by the support means. It not only movements of the shoulders, and a bending of the upper body to the left and to the right without moving the receiving container is possible in this embodiment, but also moving the upper body forward and backward. The inventive arrangement of the self-contained tension element is at best a minor adjustment or the like. Required. This means for example, that on a bicycle, the location of the backpack does not have to adjust after the upgrade, although the posture of the upper body changes significantly, for example, against the run. Thus, there is an automatic adjustment to the motion or movement of the body.

The one or the plurality of traction elements, in which it is preferably to cables in accordance with a Bowden cable or the like., Are preferably made of a low friction material or have a low-friction surface. Particularly suitable are traction elements or cables made of nylon and / or metal. This can, for example, with a Silicone coating or a Teflon coating can be provided to further reduce friction.

Likewise, the channels, eyelets, Bowden cable casings and the like., Which are provided on the receiving container or shoulder straps, be designed accordingly to reduce friction. Preferably, these elements are provided or coated with a material with low-friction surface. This may be a Teflon or silicone coating. Similarly, a permanent lubrication can be provided in addition to or instead of a coating.

Since parts of the pulling element or of the tension elements extend outside of envisaged on the receptacle channels or other holding devices, they will be preferably covered. Since between the rope and the receiving container takes place a movement which is preferably provided covers are formed preferably variable. This can be achieved in that elastic covers and / or multi-part, for example telescopable covers are provided.

If necessary, it may be desirable in certain movements of the carrier of the carrying case that movement decoupling is reduced or even eliminated completely. For this purpose, preferably an adjustment is provided, which is connected to the tension element. For example, it may be in the setting element by an adjustable spring or the like. Act the pressure on the tension member exerts and thus increases the friction at this point. Further, it may be, for the adjustment to a clamping means through which a switching on and off of the motion decoupling between receptacle and support means is possible.

It is particularly preferred that the entrance of the pulling element in a channel or the like. On the opposite side of the user's body as is Exit of the tension member from the channel or the like. Done. For example, enter the or the tension elements in the shoulder area on the back of the user in corresponding channels, wherein the or at the hip on the front, ie in the abdominal area of ​​the user, again from channels or the like escape the tension elements.. Hereby, a further improvement of the motion decoupling can be achieved.

In order to adapt the support means to the anatomy of the user, in conventional backpacks both shoulder straps are each provided with a timing belt. The two timing belt must be set separately from each other with a uniform set only by feel is possible. By the inventive provision of a tension member, in particular a single, self-contained tension element, which is opposite the shoulder straps sliding, it is possible to provide a single lashing or adjusting straps, as this automatically results in a shortening on both sides result. The two sides are therefore always set the same. Since in the carrying case of the invention only a timing belt has to be provided, is also a single-handed operation, during the cycling is particularly advantageous possible.

The movement decoupling can be carried further by the provision of variable length connecting elements whose length independently and adapts automatically when moving. The carrying system follows therefore according to the invention the movement of the body. There are thus at least partially erfϊndungsgemäß connecting elements between the support means and the receptacle provided, the length of which changes automatically when moving or adjusting. This can be achieved for example by elastic connecting elements, which are preferably arranged between the support means and the receiving container. In a backpack with two shoulder straps are preferably according to the invention between the front ends of the shoulder straps, ie arranged in the chest or abdomen ends, and the receiving container, and the rear ends of the shoulder straps, ie located at the back of the user ends and the receptacle provided in each case connecting elements. In particular, provided between the front ends and the receptacle connectors are designed to be elastic or extensible. Particularly preferably it is also possible to form the connecting elements between the rear ends and the receptacle elastically.

An elastic design of the connecting elements can, for example, will be realized by the provision of appropriate materials, such as rubber n. Likewise, also the spring elements or the like. Be provided. Also, as an elastic connecting element is a windable cable be provided, for example, during the unwinding of the rope a spring is stretched, so that the cable once it is released, will be rewound, so that the connecting element is shortened again.

In addition to or instead of providing variable-length connection elements may also the bag itself may have a certain elasticity. For example, the pocket completely or partially made of an elastic material, so that, for example, when moving a shoulder, the length of the bag is increased.

The receptacle is preferably located at the waist. This has the advantage that the weight of the backpack or carrying case is not disposed at the back, ie not located at the area that is greatly moved. Furthermore, a ventilation of the user's back and thus a decreased sweating or a better evaporation of sweat is ensured by the arrangement of the receptacle in the hip region. Furthermore, this arrangement of the receiving container has the advantage that the weight distribution is low. A further possibility for movement of decoupling that can be provided in addition or instead of the above-described decoupling of shoulder straps, is to provide a fixed body adjacent waist belt, secured to the means of a joint, especially a ball joint, the receiving container. The receptacle is thus at least pivotable about a substantially perpendicular to the back of the user and perpendicular to the waist belt extending axis. This has the consequence, that the upper body can be swung, without thereby the waist belt is moved.

According to an independent invention, a carrying case, like a backpack, provided with a receptacle and a connected to the receptacle support means. The support means includes upper and lower fasteners. Erfϊndungsgemäß are at least two connecting elements via a cable, in particular a Bowden cable or the like., Connected to each other, wherein said cable is made of a material with low-friction surface. Already by the provision of a smooth cable line between fasteners of comfort can be improved.

The cable is, in particular as described above generally with reference to a tension member, advantageously developed. In particular, a possibly likewise provided on the receiving container provided channel or the like. With a low friction surface. This may have suitable coatings or in particular of hard plastic, metal and / or Teflon, can be made.

The principle of motion decoupled carrying system according to the invention is not limited to bags and backpacks in particular. Further, instead of the receptacle, any other object, such as a life vest, a bulletproof vest, and the like. Be provided. With such support devices of the receptacle is thus through to supporting article or the carrying member replaced. In principle, the carrying system according to the invention is for all types of loads, for example, for carrying musical instruments, arms, remote controls, gas cylinders and the like., Suitable diving cylinders or tools. Further, the carrying system is due to the movement decoupling invention also good for carrying children racks or special garments such as bras and suspenders, suitable. Also back and / or shoulder protectors can be connected to a carrying system according to the invention and worn comfortable in this way.

The invention will be explained by means of preferred embodiments with reference to the accompanying drawings.

Fig. 6 is a schematic plan view of a preferred embodiment of a shoulder belt and a shoulder pad.

The backpack according to the invention comprises a receptacle 10, can be accommodated in the transportable objects. Of the Receptacle 10 is disposed at the waist of a user and supported on the hip with a hip belt 12th Further, the backpack has a supporting means 14, whereby the hip belt 12 is not part of the supporting means.

In the illustrated first preferred embodiment, the support means on two shoulder straps 16,18, which can be connected with a chest strap 20 to each other if necessary. The shoulder straps 16,18 are thus firmly to the user's body. About optionally longitudinally adjustable intermediate members 22, where it may be straps, front ends 24 of the shoulder straps are connected to 16.18 fasteners 26th The connecting elements 26 are connected to the receiving container 10th In the illustrated embodiment, the connecting elements as a common traction element is a rope 28 which is constructed according to a Bowden cable and is guided by a tubular Bowdenzugmantel 30th The Bowdenzugmantel 30 thus forms a receptacle 10 connected to the channel or a tube in which the cable pull can be moved 28th The Bowdenzugmantel 30 is firmly connected to the receptacle 10th The cable 28 can therefore be back in the direction of arrows 32 in the Bowdenzugmantel and forth. Thus, since the two intermediate elements 22 are coupled to each other via the common cable 28, a movement of an intermediate member in the one direction automatically causes a movement of the other intermediate member in the other direction. This corresponds to the natural movement of the user, as for example when cycling or climbing not both shoulders are lifted simultaneously, but usually take place opposing movements. This is for example also during rotation of the upper body of the case.

Further, the backpack of the invention has in addition to the lower connecting members 26 upper fasteners 34th The fasteners 34 are possibly via intermediate elements 36 with the rear Ends 38 of the two shoulder straps 16,18 connected. The connecting elements 34 comprise in the embodiment shown as a traction element 40 on a common cable, which is guided around a deflecting element 42nd The cable 40 is connected to the two intermediate elements 36th The deflection element 42 in turn has a channel or a Bowdenzugmantel through which the cable 40 is guided. According to the movement described in conjunction with the lower connecting members 26 causes a movement of the intermediate member 36 and one of the two shoulder straps 16,18 in a direction, for example upwards, moving the respective other intermediate member or shoulder strap down, so that a movement of the cable 40 is caused in the direction of arrow 44th

The deflection element 42, that part of the connecting elements, is connected via a further component of the connecting elements, an intermediate element 46, which may be a belt with a buckle connected to the receiving container 10th Here, the attachment point 48 is provided between the intermediate element 46 and the receiver 10 at a distance from an inner surface 50 of the receiving container. The inner side 50 is the back support surface on which the receptacle 10 bears against the back of the user. By the distance of the attachment point 48 it is ensured that the upper connecting elements are not rest 34 at the back of the user.

In a second preferred embodiment (FIG. 3) are the same and similar components are identified by the same reference numerals.

The essential difference in this embodiment is that a self-contained cable is provided, ie the lower pulley is combined with the upper cable to a common tension element or cable 52nd Of course, it must be, not uniform in order to pull. This can, as described with reference to the first embodiment, for example, belt-like intermediate members 22 exhibit and fasteners 54th What is relevant is that it is a self-contained cable or a self-contained cable element when the pack is worn. The cable 52 is guided through a channel 58 which is arranged on the outside of the receiving container 10 in the illustrated embodiment, the left side in Fig. 3 hips 56th Thereafter, the cable 52 is guided upward and runs in the back 60 diagonally upward, ie, in FIG. 3 from bottom left to top right, to a shoulder region 62.

The shoulder pads or shoulder belts 16,18 have over those described with reference to FIG. 2 shoulder pads 16,18 on the difference that the cable 52 is not fixed to the rear ends 38 (FIG. 2) connected to the shoulder pads 16,18, but shoulder pads 16,18 with a channel 64 (Fig. 6) are connected. The channel 64, which may, for example, to single eyelets or the like., Extends in longitudinal direction of the shoulder pad 16, ie, over his shoulder. The cable 52 passes through the channel 64 and is free to move within the channel in the direction of an arrow 66th When moving of the cable 52 in the channel 64 thus will be no displacement of the shoulder pad 16.18.

At the front end 24 of the shoulder pad 18, the tension element or cable 52 is guided downwards and has a connecting element 54 in the illustrated embodiment. However, the cable 52 can also go through. By connecting the two connecting elements 54 on both sides of the cable 52 is again closed and extends to in Fig. 3 right hip. Here, the cable 52 is in turn inserted into a channel 68 or a corresponding element. The cable 52 passes through the channel 68. After leaving the channel 68 of the cable 52 from the 3 right in FIG. 70 is the hip out to left shoulder region 72. The cable 52 thus extends back again diagonally, so that the cable 52 crosses at the back 70th The cable 52 is then passed through the shoulder pad 16th The shoulder pad 16 is corresponding to that of Fig. 6 shown Shoulder pad 18 is formed, so that the cable 52 is guided through a channel 64 of shoulder support 16 and the shoulder pad is connected to a connecting element 54 in the region of the lower end 24th By closing the connecting elements 54 of the cable 52 is then closed in itself.

To clarify the history of the cable 52 in Fig. 5 is shown without a storage container 10 and, if appropriate, without cable provided intermediate elements.

Likewise, the shoulder pad shown in FIG. 6 18 also in the reference to in FIGS. be provided 1 and 2 described embodiment. The upper wire 40 (Fig. 2) is then not fixed to the shoulder pads 16,18, but also through a channel 64 (FIG. 6) out. The cable is then correspondingly with connecting elements with the intermediate elements 22 (Fig. 2). In this way, a self-contained cable is also formed, as shown schematically in Fig. 4. Such a cable 74 extends from the shoulder portion 72 down to the waist region 56, then runs along the hip in a region 76, in the embodiment shown from left to right, the second waist region 70. From there, the cable 74 then to the other shoulder region 62 out. Subsequently, the cable runs 74 in the back region 60 via an unillustrated deflecting element is U-shaped from one shoulder region 62 to the other shoulder portion 72nd
