Abstract

The rucksack has a container or bag (10) connected to a carrying device (14) which can be uncoupled from the movement of the container. The carrying device can be connected to the container through length-variable resilient connecting elements (26, 34) which adapt automatically in length during movement. The carrying device has two shoulder straps (16, 18).

Description

The invention relates to a carrying bag, in particular a backpack.

In particular, in sports activities carry bags, such as backpacks, the disadvantage that, for example, when moving the shoulders and the backpack itself or a storage container of the backpack, are stored in the objects to be transported, is moved. As a result, the wearing comfort, for example in sports such as mountain biking or climbing, significantly affected.

Out DE 201 11 889 is a backpack with a carrying device in the form of two shoulder straps known, wherein in each shoulder strap a portion is provided, which has a greater elasticity. By providing such elastic areas is to be achieved that the backpack can be worn by different people without having to adapt the carrying system to the appropriate person. Furthermore, thereby a suspension of the backpack and thus a sprung power transmission is achieved. Larger and faster movements, such as those that occur during mountain biking or climbing, are transferred to the backpack despite the provision of the elastic portion, so that the backpack is moved along with it and the wearing comfort remains severely impaired.

Out CH 198 024 a backpack is known, the two straps of the carrying device on the back of the storage container are interconnected cross. The straps are attached via brackets to the storage container and slidably held in the brackets.

The object of the invention is to improve the comfort of carrying bags, especially backpacks.

The object is achieved according to the invention by the features of claim 1.

The carrier bag has a receptacle for receiving objects to be transported. Connected to the receptacle is a carrying device, such as one or more shoulder straps or shoulder straps. In order to improve the wearing comfort of backpacks and the like. Worsening property is in the carrying bag according to the invention, the carrying device relative to the receptacle movement decoupled. This means that during a movement of the body, for example the shoulder, or a turning of the upper body, the receptacle of the carrying 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. As a result, the wearing comfort is significantly improved.

To improve the wearing comfort, the carrying bag according to the invention has a carrying device connected to a receptacle. The carrying device has upper and lower connecting elements, which may be connected, for example, with shoulder straps. Likewise, a Shoulder strap for common formation of an upper and a lower connecting element serve. According to the invention, the upper connecting elements in order to enable a movement decoupling, a common tension element. The tension element, which is preferably cables, is held displaceably on the receptacle. The common pulling element extends from an upper connecting element via a deflection element connected to the receiving container to the other upper connecting element. A movement of the body, which automatically leads to moving a connecting element, thus also causes a movement of the tension element. The movement of the tension element is transmitted to the latter due to the connection to a second connection element. The distance between the two connecting elements thus remains at least substantially constant. The invention is therefore based on the finding that the movement of a body part, for example the lifting of a shoulder, usually results in the movement of another body part in a different direction relative to the carrying bag. This means that, for example, the distance between the carrying bag and a shoulder strap on one side is shortened, while it is extended on the other side. It follows that the corresponding movement is not transmitted to the receptacle due to the provision of tension elements and thus the receptacle is motion-decoupled from the support means.

It is particularly preferable to provide a single common tension element. The upper and lower connecting elements are thus connected to each other via a single tension element or formed as a single tension element. The tension element thus extends, for example, between the shoulder straps and the receptacle. In this case, the wearing comfort can be further improved if the one common tension element is closed in itself. The common tension element thus runs, for example from a connecting element or from a shoulder belt in the region of the back to the receptacle, is slidably held on the receptacle and extends in the region of the hip forward to the second shoulder strap. From this, the tension element then again runs on the back to the receptacle on which it is slidably held and is returned from the receptacle forward to the first shoulder belt. In particular, the tension element is also held displaceably on the shoulder straps.

A particular advantage of the movement decoupling according to the invention between the receptacle and the carrying device is that the fatigue is lower, in particular when carrying larger weights and / or in strenuous sports. Furthermore, a better weight distribution can be achieved by the movement decoupling according to the invention.

In a preferred embodiment, the two lower connecting elements, ie those connecting elements which are connected, for example, with the front and lower ends of the shoulder straps or the like, are formed by a common tension element. The tension element, which is designed in particular as a cable, is thus firmly connected in this embodiment with the one front end of the shoulder belt, then preferably guided by a channel or a guide member on the receptacle and then connected to the front and lower end of the second shoulder belt. About the tension element, the movement of the two lower ends of the shoulder straps is coupled. By doing so, pulling on the one end of the cable, ie, increasing the distance of the front end of the shoulder belt from the receptacle, simultaneously reduces the distance of the front end of the other shoulder belt from the receptacle. Such a provision of a common tension element is a technically simple solution for realizing the movement decoupling between the carrying device and the receiving container. Elaborate take-up device for a tensioned tension element and the like. Are not required. Furthermore, this embodiment has the considerable advantage that the movement decoupling is independent of the weight of the receptacle, which can vary greatly depending on the transported objects. In the case of purely elastic connecting elements, a movement decoupling is realized only within certain weight limits. Possibly. the tension element or parts thereof may additionally have a certain elasticity.

In a further preferred embodiment, upper connecting elements are provided, preferably with rear ends of shoulder straps, i. with the arranged at the back of the user ends of the shoulder straps connected. These connecting elements are preferably elastic in the first embodiment. The upper connecting elements may be provided instead of or preferably in addition to the lower connecting elements.

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

To realize a movement decoupling in this area, it is possible according to a further embodiment to connect the upper connecting elements in addition to or instead of their elastic configuration via a rotary member with the receptacle. Preferably, in this case, the rotary member is then centrally connected by a single intermediate element with the receptacle. A back and forth movement of the user's upper body is thus deflected via the rotary member and does not cause the receptacle to move, so that the wearing comfort is improved by providing the rotary member.

It is also possible to connect two or more pockets via rotary elements with each other. The individual pockets can thus be rotated against each other, so that a relative movement between the pockets, as in chain links or the like., Is possible. As a result, it is also realized that during a movement of the body of the user, the pockets, in particular the backpacks, are not or only slightly moved, so that the wearing comfort is improved.

In a particularly preferred embodiment of the upper connecting elements, these also have a common tension element, which may optionally be additionally formed elastic. This common pulling element is preferably connected to the two rear ends of the shoulder straps. Preferably, the common tension element is guided over a deflection element for guiding the common tension element. The deflecting element can then preferably be connected to the receptacle preferably centrally via a single intermediate element. Here, the intermediate element is particularly preferably at a distance to an inside, i. a back support surface of the receptacle connected thereto. This has the advantage that the upper connecting elements, if necessary, together with the rotary member; the common cable and / or the deflector not rest against the back of the user, so that the comfort is further improved, and the rubbing of these elements on the back and the sweating is avoided under these elements.

Both the provision of a common tension element in the lower connecting elements and in the upper connecting elements can be carried out 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 reversed, so that a rope or the like is provided on the pocket and a common channel or a common guide element is arranged between two connecting elements. Relevant is the possible relative movement between the channel or guide part and a tension element. Likewise, it is possible to arrange the tension elements or channels in a crosswise manner so that in each case a lower connecting element is connected to an upper connecting element. The tension members may be continuous cables, cords, straps, chains and the like. It is also possible that a common cable pull comprises an intermediate element, for example a load between belt or the like.

The leadership of the cable and the like. Is done either in a channel that can be designed as a closed channel corresponding to a pipe or the like., Or in an open or partially open channel. Likewise, other guide parts, such as loops or eyes may be provided.

In a further preferred embodiment, the upper tension member is not connected to the shoulder belt or the shoulder pad, but with the lower cable. The tension element is thus held displaceably on the shoulder strap. For this purpose, a channel, eyelets or the like is connected to the shoulder belt or the shoulder pad, through which the tension element is passed. This preferred embodiment of the carrying bag according to the invention further decoupling between receiving container and carrying device is realized. By this development, slippage of the shoulder straps or shoulder pads on the shoulder by movements of the user is avoided. The comfort is thus further improved.

It is particularly preferred that the lower and the upper tension element are formed as a single common tension element. In a development of the embodiment described above, it is then a self-contained tension element. This preferably extends from a shoulder region down to the hip, is then guided by the connected to the receptacle channel approximately at waist height from one to the other side of the hip, then runs from the hip back up to the other shoulder and from there U-shaped over the deflecting element connected to the receptacle to the first shoulder. The cable thus has essentially the shape of a "double U".

In a further preferred embodiment, a single, self-contained tension element, such as a cable is also provided, with which the receptacle is movably connected. An essential basic principle In the preferred embodiments, therefore, it is provided that a self-contained, with the receptacle movably connected or slidably held on the receptacle pulling element is provided.

The one or more tension elements, which are preferably cables according to a Bowden cable or the like, are preferably made of a low-friction material or have a low-friction surface. Particularly suitable are tension elements or cables made of nylon and / or metal. These can, for example, with a Silicone coating or a Teflon coating be provided to further reduce friction.

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

Since parts of the tension element or the tension elements run outside of channels provided on the receptacle or other holding devices, they are preferably covered. Since there is a movement between the rope and the receptacle, the preferably provided covers are preferably designed to be variable. This can be achieved in that elastic covers and / or multi-part, for example, telescoping covers are provided.

Possibly. It may be desired for certain movements of the wearer of the carrier bag that the movement decoupling is reduced or even completely turned off. For this purpose, an adjusting element is preferably provided, which is in communication with the tension element. For example, it may be in the adjustment to an adjustable spring or the like., Which exerts pressure on the tension element and thus increases the friction at this point. Furthermore, the adjusting element may be a clamping device, by means of which a switching on and off of the movement decoupling between the receiving container and the carrying device is possible.

It is particularly preferred that the entry of the tension element in a channel or the like. On the opposite side of the body of the user as the Exit of the tension element from the channel or the like. For example, the one or more tension elements in the shoulder region on the back of the user in corresponding channels, wherein the one or more tension elements in the hip area at the front, ie in the abdominal area of the user, again emerge from channels or the like. As a result, a further improvement of the motion decoupling can be achieved.

In order to adapt the carrying device to the anatomy of the user, in conventional backpacks, the two shoulder straps are each provided with a timing belt. The two adjustment straps must be adjusted separately from each other, whereby a uniform adjustment is possible only by feeling. The inventive provision of a tension element, in particular a single, self-contained tension element, which is displaceable relative to the shoulder straps, it is possible to provide a single lashing or timing belt, as this automatically has a shortening on both sides result. The two sides are thus always set the same. Since only one adjustment belt must be provided in the case of the present invention, a one-hand operation, which is advantageous in particular during cycling, is also possible.

The movement decoupling can also be done by the provision of variable-length connection elements, the length of which automatically or automatically adapts when moving. The carrying system thus according to the invention follows the movement of the body. There are thus provided according to the invention at least partially connecting elements between the support means and the receptacle whose length automatically changes or adapts when moving. This can be achieved for example by elastic connecting elements, which are preferably arranged between the carrying device and the receptacle. In a backpack with two shoulder straps according to the invention preferably between the front ends of the shoulder straps, ie arranged in the chest or abdomen ends, and the receptacle, and the rear ends of the shoulder straps, ie the ends located at the back of the user and the receptacle are each provided with connecting elements. In particular, provided between the front ends and the receptacle connecting elements are designed to be elastic or stretchable. It is also particularly preferred to form the connecting elements between the rear ends and the receptacle elastic.

An elastic construction of the connecting elements may be e.g. be realized by providing appropriate materials, such as rubber. Likewise, spring elements or the like. Be provided. Also can be provided as an elastic connecting element a windable rope, for example, when unwinding the rope, a spring is tensioned, so that the rope, as soon as it is relieved, is wound up again, so that the connecting element is shortened again.

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

The receptacle is preferably arranged at waist height. This has the advantage that the weight of the backpack or the carrying bag is not arranged on the back, that is, not disposed on the area that is strongly moved. Furthermore, the arrangement of the receptacle in the region of the hip ventilation of the user's back and thus a reduced sweat or better evaporation of perspiration is ensured. Furthermore, this arrangement of the receptacle has the advantage that the weight distribution is favorable.

Another possibility for movement decoupling, which may be provided in addition to or instead of the above-described decoupling of the shoulder straps, is to provide a tightly fitting to the body hip belt to which a receptacle, in particular a ball joint, the receptacle is attached. The receptacle is thus at least pivotable about a substantially perpendicular to the back of the user or perpendicular to the hip belt axis. This has the consequence that the upper body can be swiveled without the hip belt being displaced.

The cable is preferably made of a material with a low-friction surface. Already by the provision of a smooth cable between connecting elements of the comfort can be improved. In particular, a possibly provided on the receptacle channel or the like. Also provided with a low-friction surface. This may have suitable coatings or in particular be made of hard plastic, metal and / or Teflon.

The principle according to the invention of the motion-decoupled carrying system is not limited to carrier bags and in particular rucksacks. Furthermore, instead of the receptacle any other object, such as a life jacket, a bulletproof vest and the like. Be provided. In such carrying devices, the receptacle is thus replaced by the object to be supported or the support element. In principle, the carrying system according to the invention is suitable for any type of loads, for example, for carrying musical instruments, weapons, remote controls, gas cylinders and the like., Diving bottles or tools. Furthermore, the carrying system is also good for carrying children's frames or due to the movement decoupling according to the invention 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 thus be worn more pleasantly.

The invention will be explained in more detail below with reference to preferred embodiments with reference to the accompanying drawings.

Show it:

• Fig. 1 a schematic side view of a first embodiment of a backpack,
• Fig. 2 a schematic rear view of the in Fig. 1 illustrated backpacks,
• Fig. 3 a schematic representation of the course of a self-contained cable in a preferred embodiment, and

The backpack according to the invention has a receptacle 10 in which objects to be transported can be accommodated. Of the Receiving container 10 is arranged at the hip height of a user and held at the hip via a hip belt 12. Furthermore, the backpack has a carrying device 14, wherein the hip belt 12 is not part of the carrying device.

In the illustrated first preferred embodiment, the carrying device has two shoulder straps 16, 18, which may optionally be connected to one another via a chest strap 20. The shoulder straps 16,18 are thus firmly on the user's body. By way of possibly length-adjustable intermediate elements 22, which may be belt straps, front ends 24 of the shoulder straps 16, 18 are connected to connecting elements 26. The connecting elements 26 are connected to the receptacle 10. In the illustrated embodiment, the connecting elements as a common pulling element on a rope 28 which is formed according to a Bowden cable and is guided by a tubular Bowden cable sheath 30. The Bowden cable sheath 30 thus forms a connected to the receptacle 10 channel or a tube in which the cable 28 can be moved. The Bowden cable sheath 30 is firmly connected to the receptacle 10. The cable 28 can thus be reciprocated in the direction of the arrows 32 in the Bowden cable sheath. Thus, since the two intermediate elements 22 are coupled to each other via the common cable 28, moving the one intermediate element in one direction automatically causes the other intermediate element to move in the other direction. This corresponds to the natural movement of the user, since for example when cycling or climbing not both shoulders are lifted simultaneously, but usually counter-rotating movements take place. This is also the case when turning the upper body, for example.

Furthermore, the backpack according to the invention has, in addition to the lower connecting elements 26, upper connecting elements 34. The connecting elements 34 are possibly via intermediate elements 36 with the rear Ends 38 of the two shoulder straps 16,18 connected. The connecting elements 34 have in the illustrated embodiment as a pulling element 40 on a common cable, which is guided around a deflecting 42. The cable 40 is connected to the two intermediate elements 36. The deflection element 42 in turn has a channel or a Bowden cable jacket, through which the cable 40 is guided. According to the movement described with reference to the lower connecting elements 26, moving the intermediate element 36 or one of the two shoulder straps 16, 18 in one direction, for example upwards, causes the respective other intermediate element or shoulder belt to move downwards, so that a movement of the cable pull 40 in the direction of arrow 44 is caused.

The deflecting element 42, which is part of the connecting elements, is connected to the receptacle 10 via a further component of the connecting elements, an intermediate element 46, which may be a strap with a buckle. Here, the attachment point 48 is provided between the intermediate member 46 and the receptacle 10 at a distance to an inner side 50 of the receptacle. The inside 50 is the back support surface on which the receptacle 10 rests against the back of the user. The distance between the attachment point 48 ensures that the upper connecting elements 34 do not rest against the back of the user.

Likewise, the shoulder support 18 shown in Fig. 5 also in the reference to the in FIGS. 1 and 2 be described embodiment described. The upper cable 40 ( Fig. 2 ) is then not fixedly connected to the shoulder supports 16, 18, but also guided through a channel 64 (Figure 5) The cable is then correspondingly connected to the intermediate elements 22 (Fig. Fig. 2 ) connected. This is also a formed in a self-contained cable, as in Fig. 4 is shown schematically. Such a cable 74 extends from the shoulder region 72 down to the hip region 56, then runs along the hip in a region 76, in the illustrated embodiment from left to right, to the second hip region 70. From there, the cable 74 is then to the other shoulder region 62 led. Subsequently, the cable 74 runs in the back region 60 via an unillustrated deflecting element in a U-shape from one shoulder region 62 to the other shoulder region 72.
