Description

The invention relates to a backpack and in particular a bicycle backpack.

Backpacks have a container for receiving objects to be transported, see eg document EP 0 348 694 A2 , Two straps such as shoulder straps are usually connected to the container. The two risers are connected on the one hand to an upper region of the container, ie a region of the container which is arranged essentially at the level of the shoulder blades, and a middle or lower region of the container. As a result, two loops are formed, through which the user's arms are inserted, so that the two risers rest on the shoulders. Optionally, a hip belt is also connected to the container in the lower region, on the part of the weight is taken up in particular in large-volume backpacks. Furthermore, especially small-volume backpacks are known, which have only a strap. This is also connected to an upper and a middle or lower portion of the container and is usually performed diagonally across the chest of the user.

In particular, in sports or Fahrradrucksäcken there is a requirement to design these so that the backpack, including its charge in dynamic movements, such as those occurring during cycling, as little back and forth commutes and further movements of the wearer, ie the person who carrying the backpack, not immediately on transfer the backpack. Thus, it is desired that the backpack hinder its wearer as little as possible in its dynamic movements. In known backpacks, the lower end of the risers resting on the shoulders of the wearer is connected to the front of the container in a lower portion of the container. When performing dynamic movements, it may thus happen that an object that is in the container begins to move in an uncontrolled manner. This can happen in particular when the container is not completely filled and / or filled with objects with a relatively high weight.

The object of the invention is to improve the comfort of a backpack, in particular a bicycle rucksack.

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

The backpack according to the invention, which is designed in particular as a sports backpack or bicycle backpack, has a container for receiving objects. The backpack also has two risers, each connected at its upper end to an upper portion of the container. According to the invention, the lower ends of the straps or an intermediate element connected to the lower end of the straps are completely guided around the container and surround it completely from diagonally below. The lower ends of the risers or the intermediate element connected thereto are connected in a rear region of the container with this. A rear region of the container is understood to be the side of the container which is remote from the carrier of the backpack. The connection of the lower ends of the straps or of the intermediate element with the rear region of the container can for example be done by sewing, gluing, welding, etc.

According to the invention thus form the two lower ends of the straps, if necessary in conjunction with the intermediate element, a carrying loop, in which the backpack is inserted and through which it is worn. Through this strap both the weight, or a part of the weight of the backpack is taken as well as the backpack pulled in the direction of the carrier. The strap described here is similar to a trapeze as it is used for sailing or surfing.

Characterized in that the lower ends of the straps or an intermediate element connected to these encompass the container completely and obliquely from below and are connected in a rear region with these, the introduction of the carrying force of the risers takes place obliquely up in this rear region of the container. In backpacks, which are known from the prior art, however, the force is introduced in a front region of the container, since the shoulder straps are connected to the front of the container. According to the invention, it is thus possible to use an object, which is located in the container, to the body of the wearer and thus better to control. Thus, it can be prevented that this object performs uncontrolled movements and, for example, begins to commute, if the carrier z. B. just rides or runs bicycle. According to the invention, objects located in the container can then be better controlled if the container is not completely filled.

It is possible that the rear side of the container, with which the lower ends of the straps or the intermediate element are connected, has a curvature and, for example, extends in its lower portion in the direction of the front of the container, ie in the direction of the carrier. It is also possible that such a curvature results only when the backpack is on the back of the wearer. In any case, it is important that the area of the rear of the container with which the lower ends of the risers or the intermediate element are connected, not completely horizontal, so that it is possible through the straps that are guided around the shoulder of the wearer , at least one Force component in the direction of the carrier, ie to transmit a horizontal force component to the container. This is also possible, for example, when the lower ends of the straps or the intermediate element are connected to a sloping lower portion of the rear side of the container.

It is preferred that the rear side of the container extends in its central region substantially parallel to its front side and / or angled in a lower region of the container in the direction of the front side, wherein in particular the angle between the middle and the lower region when carrying the Backpacks 40 ° to 80 °, preferably 50 ° to 70 ° and particularly preferably 55 ° to 65 °. The middle region of the container thus runs substantially parallel to the back of the wearer. Since the middle and lower regions of the rear side of the container are often not completely straight, said angles can be determined on the basis of tangents of the middle and lower sections of the back side. It is preferred that a sloping underside of the container is formed by the angled lower portion of the rear side of the container at the same time and the lower ends of the straps or an intermediate element connected to them are at least partially guided around this underside and facing away from the wearer of the backpack Area with the angled portion of the rear, ie with the sloping bottom of the container, are connected thereto.

Furthermore, it is preferred that the lower ends of the risers are connected to a flat formed intermediate member widening, starting from the lower ends of the risers, so that its two outer portions, which face the risers, are substantially triangular.

Its intermediate central portion has a trapezoidal shape, or is rectangular. This middle portion of the intermediate member is connected to the rear portion or an oblique lower portion of the container, wherein the shorter of the parallel sides of the trapezoid is preferably the underside of the trapezoid. The sloping sides of the trapezoid thus form the bases of the triangles which form the outer portions of the intermediate element. The length of the two parallel sides of the trapezoid can be determined in which angle the outer portions of the intermediate element when wearing the backpack will be angled obliquely upwards.

It is further preferred that the intermediate element is connected by a respective D-shaped ring member with the lower ends of the risers, wherein the rounded side of the D-shaped ring member facing in the direction of the risers.

In a preferred embodiment, the ends of the intermediate element, which are connected to the lower ends of the risers, in a plane which is substantially perpendicular to the front of the container, pivotable. The pivoting is preferably carried out by two pivot points, which lie in the rear region of the container and / or on its inclined underside. It is thus possible that the risers can better follow the dynamic movements of the wearer, and thus these movements do not directly follow the container and the herein be transferred objects. Thus, a partial decoupling of the container from the movements of the carrier takes place.
Furthermore, it is preferred that the ends of the intermediate element are pivoted on pivoting in the direction of the container about an upper pivot point. When pivoting in a direction away from the container, the ends of the intermediate element are pivoted about a lower pivot point, wherein the upper pivot point corresponds in particular to the upper of the two points at which the intermediate element from its triangular to its trapezoidal shape merges and the lower pivot point in particular the bottom of the two points at which the intermediate element passes from its triangular to its trapezoidal shape.

It is preferred that the lower ends of the risers when carrying the backpack extend at an angle between 80 ° to 90 ° to the sloping underside of the container.

The triangular outer portions of the intermediate member are not necessarily equilateral or isosceles triangles. Instead, the two sides of the triangle running in the direction of the carrying strap can have a different length, so that the angle at which the lower ends of the carrying straps are relative to the lower section of the rear side of the container can likewise be influenced.

In a preferred development, the backpack further comprises a hip belt, wherein the hip belt according to the invention is connected in each case at its two facing the container ends with a belt or rope-shaped Hüftgurtiwischenelement whose first end an upper pivot point and the second end is connected at a lower pivot point with the container of the backpack.
A middle section of the hip belt intermediate element is in this case guided through a recess which is formed in the container-facing end of the hip belt or a connecting element connected thereto. According to the invention, the middle section of the hip belt intermediate element can be advanced along this length in this recess.

In other words, it is thus possible to displace the element having this recess along the hip belt intermediate element, so that the length of the hip belt intermediate element, which is respectively above and below this recess, changes.

The described hip belt thus makes it possible in a simple manner to change the angle at which the hip belt runs relative to the container without twisting or tangling components of the hip belt. Movements of the wearer during cycling or running are thus no longer transferred directly to the container or objects located therein. Here, too, an improved decoupling of the container from the movements of the wearer can thus be achieved.

It is preferred that the waist belt intermediate member and its associated end of the hip belt in a plane which is substantially perpendicular to the front of the container, upwards, d. H. towards the container and down, d. H. Can be pivoted away from the container.

Furthermore, it is preferable for the hip belt intermediate element and the end of the hip belt connected to it to be pivotable about two points which lie in the lower region of the container and in particular on its front side. The two points correspond in particular to the upper and lower articulation point at which the hip belt intermediate element is connected to the container.

Furthermore, it is preferred that the hip belt intermediate element and the end of the hip belt connected thereto are pivoted about the upper point of articulation when pivoting in the direction of the container and on pivoting away from the container about the lower articulation point.
In the following, preferred embodiments of the invention will be explained with reference to figures.

The in Fig. 1 illustrated bicycle backpack has a container 10 and two risers 12a, 12b. These are each connected at their upper end to the upper portion of the container 10. The connection is made according to Fig. 1 via an additional element, but can also be done directly.

The lower ends of the risers 12 a, 12 b are connected to the intermediate element 14. Its outer portions have a substantially triangular shape. Assuming that the tip of the triangle is not present, so that the D-shaped ring element can be fixed, it can also be assumed that a trapezoidal shape. The two outer regions of the intermediate element 14 are connected at the points A, B to the rear region 10b of the container 10 and in particular to a lower section of the rear side 10b pointing obliquely in the direction of the front side 10a of the container 10, which at the same time covers the underside 10c of the container Container 10 forms.

It is preferred that the connection of the intermediate member 14 to the container 10 is by stitching, the seams being designed so that they do not have to absorb forces caused by the weight of the container. Rather, it is preferred that the weight of the container on the lower side of the risers 12a, 12b be received solely by the loop-shaped intermediate member 14 extending from the rear riser 12a to the right riser 12b.

In Fig. 2 is visible as the intermediate element 14 engages around the oblique lower part of the back 10 b of the container 10, which simultaneously forms the bottom 10 c of the container 10. The container 10 is thus pulled by the risers 12a, 12b and the intermediate member 14 connected to them in a direction obliquely above, ie in the direction of the carrier, not shown, of the backpack.

The lower end of the risers 12a, 12b and the outer end of the intermediate element 14 connected to them can, as in Fig. 2 indicated by arrows are pivoted in a plane which is substantially perpendicular to the front side 10 a of the container 10. This level corresponds to the leaf level in Fig. 2 ,

The angle between the bottom 10c and the back 10b of the container 10 is according to Fig. 2 60 °, this angle especially arises when the backpack is attached to the back of the wearer. It is possible that the back 10b of the container 10 is not rigid, so that this angle is changeable and in particular is not 60 °, if the backpack is not on the back of the wearer.

The in Fig. 2 illustrated backpack also has a hip belt 18. The hip belt 18 is at its two facing the container 10 ends each with a belt-shaped. Hüftgurtzwischenelement 20 connected, the first end at an upper pivot point C and the second. End is connected at a lower pivot point D with the container 10 of the backpack.

In Fig. 2 is the upper pivot point C hidden by the intermediate element 14 and thus not visible. A middle section of the hip belt intermediate element 20 is guided through a recess 22. This is formed in the connecting element 24, which is connected to the container 10 facing the end of the hip belt 18. The middle section of the waist belt intermediate element 20 can thus be displaced along its longitudinal direction in this recess, so that the hip belt intermediate element 20 and the rear part of the hip belt 18 facing the container 10, as indicated by the arrows in FIG Fig. 2 indicated, are pivotable in a plane which is perpendicular to the front side 10 a of the container 10. This level corresponds to Fig. 2 the leaf level.

Through the connecting element 24, a detachable connection between the hip belt 18 and the waist belt intermediate element 20 can be made, so that the hip belt when applying the backpack can be comfortably guided around the waist or abdomen of the wearer and then via the connecting element 24 on the opposite side with the Waist belt intermediate element 20 can be connected.

The waist belt intermediate member 20 is guided in a tunnel member 26 having substantially the same shape and dimensions as the waist belt intermediate member 20. A corresponding exploded view of said components is shown in FIG Fig. 3 shown. The tunnel element 26 has at its tip a retaining loop 28, which is also connected to the connecting element 24.

Furthermore, the tunnel element 26 can have an attached pocket, in particular a mesh pocket 30, into which smaller objects, for example a mobile telephone or a camera, can be accommodated.

It is preferable to carry straps and hipbelt in a backpack as it is in Fig. 2 is shown to combine. To fix the backpack on the back of the wearer, it is sufficient to wear the straps 12a, 12b and the hip belt 18. Due to the pivotability of these components in leaf level according to Fig. 2 These align themselves automatically, so that a good wearing comfort for the wearer can be achieved, without having to make larger adjustments to the backpack. Rather, an optimal carrying position can be found intuitively.

In a preferred embodiment, the backpack according to the invention on its front side 10a an incorporated stiffening element, which is formed for example of plastic, on. This can be, for example, behind the back pad and serves to the front 10 a. the container 10 to give a desired shape. It is preferable that the stiffening element can be changed in shape by the carrier, so that it is possible to give the front side 10a of the container 10 different shapes according to the physique of the wearer or the desired application of the backpack. The stiffening element is preferably elongate and has a smaller width in its middle section than in its upper and lower sections.

The central portion can thus serve as a torsion element, so that the upper portion of the stiffening element can be rotated relative to its lower portion and the stiffening element can better follow the movements of the wearer of the backpack.
