Description

Technical Field

[0001] The utility model relates to a bearing device for bearing a load. Background Art

[0002] From the prior art, a carrying device for carrying a load is known, which is arranged on the body of the user by means of a belt. In order to adapt the carrying device to the body size, buckles are provided on the belt, which can be used to reduce the length of the belt loop when pulling at the free belt end extending from the buckle. The disadvantage of this structure is that a long free belt end is formed, which can hinder the user of the carrying device, get tangled with other belts or get dirty when the carrying device is put down. For this purpose, a solution known in the prior art is to provide a receiving bag or other device for storing the free belt end. Providing such a bag increases the production expenditure and manufacturing costs of the carrying device. In addition, after the belt end is stored in the bag, it is no longer possible for the user to quickly adjust the length, so that the user can no longer adjust the carrying device according to his needs and / or the current load situation, and the wearing comfort and efficiency of the carrying device are reduced.

[0003] The object is therefore to provide a carrying device having an improved length adjustment mechanism. Utility Model Content

[0004] The utility model relates to a carrying device for carrying a load, in particular a tool and / or an implement, wherein the carrying device can be arranged on the body of a user by means of at least one carrying belt, in particular a shoulder belt and / or a waist belt, wherein the length of the carrying belt can be adjusted so as to be adapted to the body size and / or the carrying situation of the user. According to the utility model, the carrying belt is composed of at least three belt segments, which can be positioned relative to each other so as to adjust the length of the carrying belt, wherein the first belt segment can be adjusted relative to the second belt segment in discontinuous steps, and the third belt segment can be adjusted relative to the first belt segment and / or the second belt segment in a stepless manner.

[0005] In particular, products that are mainly formed from textile components are referred to as load-bearing devices, which can be worn by a user in order to fasten one or more loads to be carried on the product and thereby enable the user to carry one or more loads more efficiently and / or more ergonomically. The load-bearing device is fastened / can be fastened to the user's body, preferably the shoulder area and / or waist area, by at least one load-bearing belt. The load-bearing device can include a waist belt, to which the load is fastened. The load-bearing device can include shoulder straps, to which the load is fastened. The load-bearing device can include a back panel, to which the load is fastened and which is connected to the user by at least one shoulder strap and in particular a waist belt. In this case, the back panel can be constructed in particular by a plastic component. Instead of the back panel, a back part consisting of textiles and / or pressed foam can also be provided.

[0006] The carrier belt is in particular mainly a textile product, wherein the carrier belt can have buckles or similar connecting elements made of metal or plastic. A part of the carrier belt is understood to be a belt segment, which together with at least one other belt segment forms the carrier belt. The belt segment has an elongated basic shape and a first end and a second end with respect to the longitudinal direction of the belt segment, wherein the length of the belt segment extends between the first end and the second end. In one embodiment, the belt segment advantageously has a substantially uniform cross-section and / or structure in the longitudinal direction of the belt segment. It can be provided that the belt segment is formed by a flat strip or an especially long cushioning part.

[0007] The load to be carried has in particular a weight of less than 50 kg, in particular less than 20 kg. The load can include one or more tools, in particular hand-held tools (e.g. axes, shears, measuring tools or similar hand-held tools usually required in gardening / forestry or construction) and / or implements, in particular motor-driven working tools (e.g. brush cutters, bush cutters, blowers) or other portable working tools and / or their battery packs. The carrying device can thus facilitate the transport and / or use of the tools and / or implements and / or the battery pack by absorbing at least part of the weight and / or operating forces of the tools and / or implements and / or the battery pack via the carrying device and transmitting them to the carrying body.

[0008] In order to adapt to the user's body size and / or load situation or working situation, the length of the carrying belt, especially the shoulder belt and / or waist belt, can be adjusted by adjusting the length. Here, the adjustment of the length of the carrying belt is carried out at least in a stepless part and in a discontinuous part, so that the belt segments belonging to the carrying belt can be adjusted relative to each other. The first belt segment can be relatively adjusted relative to the second belt segment with a discontinuous level, that is, a predefined distance. In addition, the first belt segment or the second belt segment can be relatively adjusted relative to the third belt segment steplessly. The overlap (überlappung) of the belt segments is changed by the relative adjustment of the belt segments. The length of the carrying belt is increased by reducing the overlap, and the length of the carrying belt is reduced by increasing the overlap. The adjustment length corresponds in particular to the sum of the changes in the individual overlaps of the belt segments of the carrying belt. The feasible overlap is determined in terms of structure by the number and size of the discontinuous levels or the selected length of the belt segment that can be pulled through the second fixing device. The free belt end overlaps with the same or other belt segments.

[0009] Due to the presence of discontinuous rough adjustment and stepless fine adjustment, the adjustment length is distributed to two fixing devices and the length prepared for the stepless length adjustment can be reduced at the second fixing device. The disadvantages of the prior art are thus eliminated, so that even when the carrying device is set to a smaller size, there will be no longer free belt ends that hinder the user. The vast majority of the adjustment length is provided by adjusting the belt segments relative to each other in discontinuous rough steps. Discontinuous adjustment is advantageously initially performed when the carrying device is first applied to the user, wherein the user can set the carrying device to, for example, a small, medium or large level according to his individual body size. Stepless adjustment is particularly useful for fine setting, for example for adjusting according to the thin or thick clothes of the user. Therefore, only a small part of the adjustment length needs to be prepared for the stepless adjustment, so that even when set to the smallest size, the maximum released belt end is reduced relative to the prior art.

[0010] In one embodiment, the first belt segment and the second belt segment can be fixed relative to each other and are in particular fixed to prevent relative movement by a first fixing device, wherein the first fixing device is composed of a first component (in particular a retaining protrusion extending from the first belt segment) and a second component compatible with the first component, in particular a tab-shaped component, and the first belt segment has a first component and the second belt segment has at least two second components, wherein the second components are arranged at a discontinuous distance relative to each other in the longitudinal direction of the second belt segment, i.e. in the direction of the length of the second belt segment. The discontinuous distance is in particular assigned to a discontinuous step of the length adjustment of the carrier belt. Therefore, for the length adjustment, the first component of the first belt segment is separated from the second component of the second belt segment and connected to other second components of the second belt segment arranged at a discontinuous distance. In this way, the belt segments are quickly and easily positioned and fixed relative to each other. The overlap of the first belt segment relative to the second belt segment is changed by moving the first component. The achievable adjustment length of the discontinuous length adjustment of the carrying device, i.e. the variation between the minimum and maximum steps, can be determined by the number of second components present at the second belt segments and the distance of these second components relative to one another. The discontinuous spacing between adjacent second components can be uniform or different from one another. If the carrying device has a plurality of first belt segments, which are connected to one or more second belt segments, the discontinuous steps of the second components of the second belt segments are matched to one another. In this way, the left shoulder strap and the right shoulder strap of the carrying device can be adjusted symmetrically, for example, in discontinuous steps of equal size.

[0011] In one embodiment, the first belt segment is formed by a flat belt-shaped section, and the first component of the first fixing device is arranged at the first belt segment, in particular at the first end of the first belt segment. The first component of the first fixing device can be configured as a retaining protrusion, in particular a hook-shaped retaining protrusion, at the first belt segment. In particular, the retaining protrusion is implemented integrally with the flat strip and in one embodiment comprises a reinforcing sheet sewn into the flat strip. The arrangement of the first component at the first belt segment, in particular at the first end of the first belt segment, enables cost-effective production of the first component. The first component is produced in particular by folding and sewing the end of the flat strip once or multiple times, thereby obtaining a shape that protrudes from the belt segment, in particular a hook-shaped shape. In order to increase the rigidity of the retaining protrusion, a plastic sheet can be inserted in particular into the folded area.

[0012] In one embodiment, the retaining projection is designed in a hook shape and covers the second part with a part of its length in the longitudinal direction of the second belt segment. The hook shape of the first part enables a particularly load-bearing connection between the first and second parts. In order to release the first part from the second part, the first belt segment is first moved in the longitudinal direction of the second belt segment by the length covered by the hook-shaped retaining projection, after which it can be pulled out of the second part in the opposite direction. The weight force of the load acting directly or indirectly on the first belt segment pulls the hook to overlap the second part, which is in the form of a web. Such a design is particularly robust and is particularly suitable for use in the case of particularly dynamic movements of the wearer of the carrying device.

[0013] The second belt section is in particular at least partially padded. This increases the wearing comfort of the support device. Advantageously, the belt is padded in those areas in which the forces caused by the load are transmitted from the support device to the user. The belt section that is supported at the shoulders of the user is in particular padded in order to introduce the forces comfortably into the shoulders. The belt section that is supported at the waist of the user is in particular padded in order to introduce the forces comfortably into the pelvis.

[0014] In one embodiment, at least two second components are arranged in the padded section of the second belt segment. In order to change the discontinuous length adjustment, it is particularly provided that the pad is compressed. In order to discontinuously move the first component of the first belt segment, the first component must first be separated from the second component. The first component is particularly configured as a retaining protrusion protruding from the belt segment. The first component, in particular the retaining protrusion, is thicker than the second component, in particular the web-shaped component. Since the second component is arranged in the padded section, in particular the web is placed on the pad, the first component can pass through the second component when the pad is compressed. In order to connect the first component to the discontinuously spaced second component, the first component passes through the second component when the pad is compressed. Once the first component passes through the second component, the compressed pad is relaxed again. The retaining protrusion that is also squeezed can also relax again and hang on the web. Therefore, the first belt segment and the second belt segment are fixed relative to each other by the connection of the first component and the second component, in particular the connection of the retaining protrusion and the web. The padding prestressed by the first belt section increases the frictional connection between the first belt section and the second component, thereby preventing the first component and the second component from unintentionally loosening even when the carrying belt is laid down and is therefore unloaded. In the simplest way, the padding is compressed when the belt is unloaded, so that a discontinuous length adjustment is not provided, in particular for dynamic length adjustment during use of the carrying device.

[0015] In one embodiment, the third belt segment can be fixed, in particular fixed to prevent relative movement, relative to the first belt segment or relative to the second belt segment by a second fixing device, and the length of the free belt end extending at the second fixing device varies depending on the position of the second fixing device that can be continuously moved relative to the longitudinal direction of the first belt segment or the second belt segment. The second fixing device is advantageously formed by a buckle, a clip or the like, at which at least one of the belt segments can be continuously pulled through in order to increase the overlap and in this case reduce the length of the carrier belt. The other belt segments can also be continuously pulled through the buckle in order to provide additional overlapping lengths or adjust the length. In one embodiment, the other belt segments are connected to the buckle with their ends in an invariable length, for example sewn or reversibly hung into the buckle. The second fixing device is particularly provided for dynamic length adjustment during use of the carrier device.

[0016] In one embodiment, the belt segment belonging to the free belt end has a length of less than 50 cm, in particular less than 40 cm, and in particular less than 25 cm. The free belt end extends from the second fixing device to the end of the corresponding belt segment. In the case of the maximum possible shortening of the length of the carrier belt, the length of the free belt end can correspond at most to the length of the belt segment. It is thus ensured that the free belt end is shorter than 50 cm, in particular shorter than 40 cm and in particular shorter than 25 cm. Since the second fixing device is usually not used in the end positions of the adjustment range, but dynamically between these end positions, the free belt end is again significantly shorter than the length of the corresponding belt segment when the carrier device is used.

[0017] In one embodiment, at least two, in particular at least three, in particular four first belt segments can be fixed in discontinuous steps at the second belt segment, in particular at the same second belt segment. By providing a plurality of first fixing devices, the adjustment length that can be provided by discontinuous length adjustment can be increased and thus replace another part of the adjustment length that can be adjusted steplessly. If multiple groups of second components are arranged on the length of the belt segment, the second belt segment with padding is used particularly efficiently. In particular, one group is arranged in the first section and another group is arranged in the other second section. In an embodiment in which the second belt segment is supported at the shoulders of the user, the second belt segment has two front sections and at least one, in particular two rear sections, and each section of the sections is provided with a group of second components. In this way, a carrying device with particularly short free belt ends can be realized.

[0018] In one embodiment, the carrying belt comprises a shoulder belt and a waist belt, wherein the shoulder belt has at least a first belt segment and a second belt segment, and the third belt segment is configured at the waist belt. Alternatively, the third belt segment is part of the shoulder belt and is connected to the waist belt in an invariable length. The third belt segment is fixed relative to another belt segment, specifically relative to the first belt segment or the second belt segment, by a second fixing device. The length of the carrying belt is shortened by pulling at the free belt end extending from the fixing device. The third fixing device is particularly arranged on the front side of the user so as to achieve good accessibility to the free end during the use of the carrying device. In one embodiment, the carrying belt has a padded second belt segment supported at the shoulder of the user and a first belt segment extending toward the waist belt on the front side of the second belt segment. Here, the first belt segment can be connected to the waist belt directly or indirectly, that is, through another belt segment. Correspondingly, the third belt segment is configured at the waist belt or the belt segment belonging to the shoulder belt. One or more belt segments fixed at the waist belt can be particularly reversibly connected to the waist belt. In this way, on the one hand the shoulder straps can be easily cleaned or replaced and on the other hand the waist belt can be used with alternative shoulder straps or without shoulder straps.

[0027] Figure 1A , Figure 1B , Figure 2A , Figure 2B , Figure 3 and Figure 5 The schematic diagram shows a carrying device 1 with a carrying belt 2, which includes two shoulder belts 3, 4 and a waist belt 5. One or more loads 7 can be mounted on the carrying device 1. The load 7 can be, in particular, a battery pack, a forestry tool or a motor-driven work tool that is transported or moved. For this purpose, a transport tab 72 can be provided on the carrying belt, to which the load is connected.

[0028] The left shoulder strap 3, which is not visible from the user's perspective, is constructed identically to the right shoulder strap 4. The shoulder straps 3, 4 comprise a front section 24 and a rear section 25 directed toward the user. Figure 1A and Figure 1B In the embodiment of the invention, the carrying device 1 comprises a back plate 6, to which the rear section 25 and the front section 24 of the shoulder straps 3, 4 are connected. Figure 2A , Figure 2B , Figure 3 and Figure 5 In the embodiment of the invention, the rear section 25 and the front section 24 of the shoulder straps 3 and 4 are connected to the waist belt 5. It can be advantageous to provide a transverse connection between the shoulder straps 3 and 4 in order to prevent the shoulder straps 3 and 4 from sliding sideways. Figure 4A and Figure 4B Remain independent as shown in Figure 5 As shown in FIG. 2 , a common rear section 25 is formed.

[0029] The carrier belt 2 is composed of a plurality of belt segments 10, 20, 30, which are fixed relative to each other by at least one first fixing device 40 and at least one second fixing device 50. The first fixing device 40 allows the corresponding belt segments 10, 20 to be discontinuously adjusted relative to each other, and the second fixing device 50 allows the corresponding belt segments 10, 30 to be infinitely adjusted relative to each other. Figure 1A , Figure 1B , Figure 2A , Figure 2B , Figure 3 and Figure 5 In the embodiment of the present invention, the front section 24 of the shoulder straps 3, 4 can be adjusted in length discontinuously by the first fixing device 40 and steplessly by the second fixing device 50. Figure 2A , Figure 2B , Figure 3 and Figure 5In the embodiment of the invention, the rear section 25 of the shoulder straps 3, 4 can also be discontinuously adjusted in its length by means of a further first fixing device 40. Figure 1B or Figure 2B ,exist Figure 1A or Figure 2A The middle shoulder straps 3, 4 are shortened discontinuously in their length only by the first fastening device 40. Despite the adaptation of the carrying belt 2 to small body dimensions, the free belt ends 51 extending from the second fastening device 50 still have the same length L 51 .

[0030] The following is based on Figure 4A and Figure 4B The detailed construction of the first fixing device 40 and the second fixing device 50 is described with reference to the embodiment of the present invention, but is applicable to all embodiments included in the specification. The same elements are provided with the same reference numerals.

[0031] Figure 4A or Figure 4B The shoulder straps 3, 4 of the carrying device 1 are shown, wherein the left shoulder strap 3 and the right shoulder strap 4 are connected to each other via a transverse connection. The shoulder straps 3, 4 have two front sections 24 and two rear sections 25, wherein a first fixing device 40 is arranged at all sections 24, 25. In addition, a second fixing device 50 is arranged at the front section 24, respectively. The first fixing device 40 fixes the first belt segment 10 relative to the second belt segment 20. The second fixing device 50 fixes the first belt segment 10 relative to the third belt segment 30.

[0032] The first belt segment 10 is designed as a belt 18 and has a first component 41 designed as a retaining projection 75 at its first end 11. In an alternative variant, the retaining projection 75 can also be at a distance from the first end 11 of the first belt segment 10, wherein the distance corresponds to the length L of the first belt segment. 10In particular, at most 20%, particularly at most 10%. The second belt segment 20 is configured as a cushioning component 28 and has a group of second components 42, 43, 44. The first component 41 and the group of second components 42, 43, 44 form a first fixing device 40. In this embodiment, a group of second components 42, 43, 44 includes three second components 42, 43, 44, which are arranged relative to each other at a uniform spacing. In particular, if the spacing a between the upper sides 65 of the second components 42, 43, 44 (which corresponds to the size of the discontinuous level d) should be reduced and / or a larger adjustment length is to be provided, a larger number of second components 42, 43, 44 per group can also be provided, in particular 4, 5 or 6. The feasible adjustment length at the first fixing device 40 is generated by the overlap u of the first belt segment and the second belt segment. By transferring the first component 41 from the upper (uppermost) second component 42 to the lower (lowermost) second components 43, 44, the overlap amount u is reduced and thus the length corresponding to the distance a, a' between the two upper sides 65 of the second components 42, 43, 44 is released. By transferring the first component 41 from the lower (lowermost) second components 43, 44 to the upper (uppermost) second component 42, the overlap amount u is increased and the length corresponding to the distance a, a' between the two upper sides 65 of the second components 42, 43, 44 is constrained.

[0033] The size of the discontinuous step d, i.e. the spacing a, a' between the upper sides 65 of two adjacent second parts 42, 43, 44, is, for example, at least 4 cm and at most 12 cm, in particular at most 6 cm. The finer the discontinuous step d, the more steps are required to achieve the desired adjustment length, and the first part 41 will have to be inserted through more second parts 42, 43, 44 as necessary. On the other hand, the discontinuous step d should also not be larger than the adjustment length that can be provided in a stepless manner. In this way, any arbitrary length L2 of the carrier tape 2 can be combined with a discontinuous and stepless length adjustment. The length L2 of the carrier tape 2 is adjusted at the maximum overlap u max The case has the minimum discontinuity length L 2min , and at the minimum overlap u min The case has a maximum discontinuity length L 2max This discontinuous length can also be adjusted by means of a stepless length adjustment.

[0034] If the first fixing means 40 are arranged on the front side and on the rear side on the carrier belt 2, they are adjusted, for example, in both cases in the same discrete steps d, so that the carrier belt 2 is not moved forward or backward. Figure 4A or Figure 4BFor the shoulder straps 3, 4, in the case of adjustment in discontinuous steps d at the front section 24 and the rear section 25 of the shoulder straps 3, 4, a length change of at least 8 cm and at most 24 cm, particularly at most 12 cm, is achieved. In the case of adjustment in two discontinuous steps d, the length change is doubled as long as the discontinuous steps d are the same size. Therefore, a length change of, for example, 24 cm can be achieved using a set of three second components 42, 43, 44 arranged in steps of 6 cm. This adjustment length no longer needs to be provided by a stepless second fixing device 50, so that the belt segment on the second adjustment device can be shortened by a total of 24 cm. In a load-bearing device according to the prior art without additional discontinuous length adjustment, the entire adjustment length must be prepared at the stepless fixing device 50, so that the length L of the free belt end 51 51 Relatively large when set for smaller body sizes.

[0035] The right front section 24 of the shoulder strap 4 shows how the first part 41 of the first belt segment 10 and the uppermost second part 41 of the second belt segment 20 interact to fix the two belt segments relative to each other. The retaining projection 75 is hooked in the uppermost tab 66. The retaining projection 75 is designed in a hook-like manner in the illustrated embodiment and engages the tab 66 from behind. In an alternative embodiment, the retaining projection 75 can also be abutted against the upper side of the tab 66, that is, not engage the tab 66 from behind. The length L of the first belt segment 10 10 This is selected so that the lower second end 12 of the first belt segment 10 is still located below the second belt segment 20 even when the first component 41 is fixed to the uppermost second component 41. In other words, the length L of the first belt segment 10 is 10 The distance between the upper side 65 of the uppermost second component 42 and the lower end 21 of the second belt segment 20 is greater than the distance between the upper side 65 of the uppermost second component 42 and the lower end 21 of the second belt segment 20. This design allows the first belt segment 10 to be fixed to the selected second component 42, 43, 44 on the one hand, and on the other hand, it can also be extended at its length L 10 The first belt segment 10 is guided upward through the group of other second components 42, 43, 44. The second components 42, 43, 44 (to which the first component 41 is not currently fixed) guide the second belt segment 20 extending through them. As shown in the left front section 24, in order to achieve guidance of the first belt segment 10 even when the first component 41 is hung on the lowermost second component 44, a guide tab 73 is provided between the lowermost second component 44 and the lower end 21 of the second belt segment 20. Compared to the second components 42, 43, 44 configured as tabs 66, the guide tab 73 has a height that is reduced in the longitudinal direction 82 of the second belt segment 20.

[0036] The second part 42, 43, 44 designed as a tab 66 is connected to the second belt segment 20 at its wide sides 67, in particular sewn, and the high sides 68 located between the wide sides are open, thereby forming a channel 69 that is open in the longitudinal direction 82 of the second belt segment 20. The upper high side forms the upper side 65 of the second part 42, 43, 44. The wide side 67 extends in particular parallel to the longitudinal edge of the second belt segment 20. The width B of the channel 69 is 69 The depth of the channel 69 is approximately zero, i.e. the tabs 66 and the pads 28 of the second belt segment 20 are flat against each other. Since the depth of the channel 69 is approximately zero in the initial state, the pads 28 must first be compressed when the second components 42, 43, 44 are pushed into the first component 41 and the width B of the channel 69 is reduced. 69 The length L of the channel 69 is converted into a portion of the channel 69. The dimensions indicated relate to the undeformed state of the second component 42, 43, 44. 69 corresponds to the spacing of the high side 68 and is measured along the longitudinal direction 82 of the second belt segment 20. The length L of the channel 69 69 is the width B of channel 69 69 The channel 69 is shorter than the width, in particular at most 50% to 100%, particularly at most 60% to 80%. The first belt segment 10 configured as a belt 18 has a width B measured transversely to the longitudinal direction 81 of the first belt segment 10. 18 The width B of the strip 18 is 18 For example, at the width B of channel 69 69 In this way, the first belt section 10 is well guided beside the wide side 67 of the tab 66 and can at the same time be pushed through the channel 69 using normal hand force. The length L of the holding projection 75 measured in the longitudinal direction 81 is 75 Especially at the length L of the channel 69 69 The width B of the strip 18 is between 80% and 120%, in particular between 90% and 110%. As a result, the retaining projection 75 can be pushed into the tab 66 from below and can engage the tab 66 from above and can be pulled out of the tab. 18 For example, it is 2 cm to 5 cm, in particular about 2.5 cm. The length L of the channel 69 69 The length of the retaining projections 75 is, for example, 2 cm to 5 cm, in particular about 2.5 cm. The width B of the channel 69 69 For example, it is 2.5 cm to 6 cm, in particular 3 cm to 4 cm.

[0037] The distance between adjacent webs 66 relative to one another is, in particular, the length L of the channel 69. 69The spacing is between 100% and 300%. The spacing is in particular 2 cm to 10 cm, in particular 2 cm to 5 cm. Thus, on the one hand, the retaining projection 75 can be well inserted into the tab 66 and on the other hand, the first belt segment 10 can be tightly guided through the other second components 42, 43, 44. Figure 6 A detailed view of the first fixing device 40 is shown, from which it can be seen that the channel 69 extending between the high sides 68 of the tabs 66 is designed to be narrower than the thickness of the first component 41 arranged at the first end 11 of the first belt segment 10. When the first component 41 is pushed in, the pad 28 is compressed in the area of ​​the tabs 66 and the channel 69 is thereby expanded. After the first component 41 is pulled out of the channel 69, the pad 28 relaxes again, the channel 69 becomes narrower and rests slightly on the first belt segment 10. The friction between the tabs 66, the first belt segment 10 and the pad 28 of the second belt segment 20 reduces the tendency of the first belt segment 10 to slip out in the channel 69. Figure 6 It can be seen that the first band section 10, which is constructed as a band 18, is wound at its first end 11 and is therefore thickened. The stitching 77 in the upper half of the winding, in particular the upper third and extending transversely to the longitudinal direction 81, tightens the winding and forms the first component 41 constructed as a retaining projection 75. Here, a plastic sheet 76 can be rolled in together in order to further increase the rigidity of the retaining projection 75. Alternatively, more windings (Wicklungsrunden) can be provided, which are connected to each other, for example, in particular by adhesive or stitching. The increased rigidity makes it easier to push the retaining projection 75 through the narrow channel 69. In addition, the folding of the retaining projection 75, which is constructed in a hooked manner in the embodiment, is prevented.

[0038] The second fixing device 50 fixes the first belt segment 10 designed as a belt material 18 relative to the third belt segment 30. In order to illustrate different variants, Figure 4A or Figure 4B The left front section 24 of the shoulder strap 3 and the right front section 24 of the shoulder strap 4 are shown in different embodiments. Figure 4A or Figure 4B in or Figure 1A or Figure 1B as well as Figure 2A or Figure 2B The third belt section 30 can be part of the shoulder straps 3, 4, as in the right front section 24 of the shoulder strap 4 shown by way of example in FIG. Figure 4A or Figure 4B in or Figure 3The third belt segment 30 can also be part of the waist belt 5, just like the left front section 24 of the shoulder belt 3 shown as an example in the figure. Accordingly, the third belt segment 30 can be implemented as a belt 18 or a padding part 28. The second fixing device 50 can be formed by a buckle 52, in particular a ladder buckle, a clip or a similar element, at which at least one free belt end 51 protrudes, and at which it can be pulled in order to continuously reduce the length L2 of the carrying belt. As long as no adjustment is made at the second fixing device 50, the length L2 of the free belt end 51 protruding at the second fixing device 50 is 51 It will not change. Here, it is not important for the stepless length adjustment whether the free belt end 51 belongs to the first belt segment 10 or the third belt segment 30, that is, the second fixing device 50, in particular the buckle 52, the clip or the like is connected to one belt segment or another belt segment in a non-variable length manner. Here, only the position at which the free belt end 51 is arranged on the carrier belt 2 and the way in which the free belt end is oriented relative to the carrier belt 2 are changed. However, if the free belt end 51 is also configured at the same belt segment as the first component 41, it can be achieved that the user - as is accustomed to conventional carrier belts - only pulls at the free end, instead of changing the suspension of the first component 41 in one or more discontinuous steps d. In order to avoid the occurrence of a longer free belt end 51 due to this behavior, a stopper 79 can be provided at the belt segment, which does not hinder the discontinuous length adjustment, but cannot be passed through the second fixing device 50. The adjustment length of the stepless length adjustment is thus limited and the free belt end 51 accompanying it is therefore limited. However, such an erroneous operation can be avoided in the simplest way if the free belt end 51 of the second fixing device 50 is not formed on the same belt section as the first part 41 of the first fixing device 40 .

[0039] In accordance with Figure 3 In the embodiment of the present invention, the free belt end 51 is configured at the first belt section 10. A stopper 79 can be provided at the first belt section 10, which limits the through-drawing of the first belt section 10 to a determined length in order to avoid a longer belt end 51. The second fixing device 50 is implemented as a reversible separation point 80 between the shoulder straps 3, 4 and the waist belt 5. In all other embodiments, the shoulder straps 3, 4 can also be reversibly connected to the waist belt 5 at the reversible separation point 80, in particular hung on the waist belt.

[0040] In accordance with Fig. 7A or Figure 7B In the embodiment of the present invention, the waist belt 5 can be discontinuously and steplessly adjusted to adapt to the user's body size. Figure 1A , Figure 1B , Figure 2A, Figure 2B , Figure 3 , Figure 4A and Figure 4B In the embodiment of the present invention, the waist belt 5 can be part of the carrying device 1 and form the carrying belt 2 together with the shoulder belts 3 and 4. Alternatively, the waist belt 5 can also form the carrying belt 2 alone. At least one first fixing device 40 and a second fixing device 50 are arranged on the waist belt 5. The second belt segment 20 has a set of second components 42, 43, 44 at its ends 21, 22, respectively, which form the first fixing device 40 with the corresponding first component 41 of the first belt segment 10. The first belt segment 10 and the other first belt segments 10 can be fixed relative to each other by the second fixing device 50, especially in the form of a buckle 52. At least one free belt end 51 protrudes at the second fixing device 50, and it can be pulled at the free belt end to reduce the length L2 of the carrying belt 2 steplessly. One of the two first belt segments 10 forms the third belt segment 30. The description of the first fixing device 40 and the second fixing device 50 that have been made for the previous embodiment can also be transferred to this embodiment. In order to avoid repetitions, reference is made here to the description of the figures, in which identical elements are provided with the same reference numerals.
