Description

Technical Field

[0001] The invention relates to a carrying device for carrying a load by a user, in particular for carrying a hand-held tool such as a brush cutter or the like, the carrying device comprising: at least one shoulder strap for wearing the carrying device on the shoulders of the user; and a side leg plate having a connecting unit for fastening the tool, wherein the leg plate is held on the carrying device by a carrying strap, and the carrying strap is effectively connected to the shoulder strap at one end, and the leg plate can be moved along the carrying strap on the carrying strap. Background Art

[0002] Carrying devices for carrying loads are known, for example carrying devices for working with brush cutters. The carrying device essentially comprises a back plate with shoulder straps and a waist belt, wherein the leg plates are held on the carrying device by the carrying belts. The leg plates have a connecting unit on their outer side facing away from the user for fastening a tool, wherein the weight of the tool is transferred to the carrying device via the leg plates and the carrying belts.

[0003] Brush cutters can be moved essentially in the horizontal direction according to the principle of a sickle for mowing grass, cutting bushes or the like. In this case, the position of the leg plate on the carrying belt can change, which can be disturbing to the user. If vertical working movements must be performed with the tool, for example when it is necessary to work on a slope or trim bushes or the like, a movement of the leg plate on the carrying belt can be expedient.

[0004] The users usually work with different working techniques. A first user turns his hips while mowing and does not want the leg panel to move forward automatically, while another user wants the leg panel to slide on the carrying belt while mowing. Summary of the invention

[0005] The object of the present invention is to design a carrying device for carrying a hand tool by a user so that the carrying device can easily carry out various working techniques preferred by the user and can also be used easily and purposefully, independently of the working technique.

[0006] This task is achieved in that a positioning device is functionally arranged between the carrying belt and the leg plate, the positioning device having a release position and a locking position. In the release position, the leg plate can be moved along the carrying belt, while in the locking position, the leg plate is immovably fixed to the carrying belt. The locking position can correspond to a first operating mode of the tool, and the release position can correspond to a second operating mode of the tool.

[0007] In the released position of the positioning device, the positioning device functionally arranged between the carrying belt and the leg plate is movable along the carrying belt, while in the locked position of the positioning device, the leg plate is immovably fixed to the carrying belt. "Immovable" means that the leg plate will not move on the carrying belt due to working movements.

[0008] The term load-bearing belt includes not only flat belts with a rectangular cross section, but also belts with other cross sections, such as load-bearing ropes or similar elements.

[0009] By designing the carrying device according to the invention, the carrying device can be used in a first operating mode in the locked position of the positioning device and in a second operating mode in the released position of the positioning device. In this way, the carrying device can also be adapted to the preferred working technique of the user, for example to various application situations of a hand-held tool, in particular a brush cutter or the like.

[0010] The leg plate expediently has a belt channel for the support belt, wherein the support belt extends through the belt channel in the direction of the channel center axis.

[0011] The positioning device can be configured to include a positioning element that is displaced into the free cross section of the belt channel in the locked position. Since the cross section of the belt channel is reduced in the locked position of the positioning device, the carrier belt cannot move in the belt channel without increasing the force consumption, thereby achieving positioning.

[0012] In a special embodiment of the invention, the locking device is held on the leg plate, which is in particular designed as a clevis held on the leg plate. To achieve the locked position of the locking device, the user grasps the support belt between the free channel sections of the belt channel and pulls it laterally out of the belt channel in order to fix the support belt to the clevis. The clevis is expediently designed for this purpose on a flat surface of the leg plate.

[0013] In a simple design of the invention, the positioning device is held on the carrier tape. Therefore, the positioning device can include a positioning element held on the carrier tape. An embodiment of the positioning element can be a clip attached to the carrier tape. The positioning element can also be designed so that it is embedded in the carrier tape in a form-locking manner, for example, penetrates the carrier tape or the like.

[0014] In a development of the invention, the tool held on the connecting unit has a guide rod and a tool head arranged at one end, wherein the belt channel of the leg plate is spaced apart from the guide rod.

[0015] As a further independent invention, it can be provided that the carrying belt is connected to the side straps of the carrying device by means of a buckle between the ends of the leg plate which are effectively connected to the carrying belt and the shoulder strap. In this case, the buckle is arranged to be movable in the longitudinal direction on the carrying belt. This enables the user to adjust the connection point between the side strap and the carrying belt according to his wishes and the working situation. In order to locate the selected adjustment state, it is advantageous if the buckle uses a clamp with at least one operating wing, by means of which the buckle can be fixed along the carrying belt in at least one direction. In particular, the clamp has a spring element, which holds the clamp in the locked position. The spring element is in particular designed as a leg spring. It can be expedient if the spring element is constructed in one piece with the clamp.

[0016] In an advantageous embodiment of the invention, the buckle comprises two clamps, each having an operating wing. The buckle thus has two operating wings. Each clamp prevents the carrier belt from sliding out in the respective carrier belt longitudinal direction, so that the buckle is completely positioned on the carrier belt. In order to move the buckle in both longitudinal directions of the carrier belt, i.e. freely, the two operating wings can be operated together, i.e. the two clamps are released.

[0017] The operating wing is arranged here so that it can be operated by two fingers of the user together. Thus, when the user wears the carrying device, he can operate the clamp with two fingers of one hand, release the clamp, and make longitudinal adjustments on the carrying belt as required. It is not necessary to remove the carrying belt in order to move the buckle on the carrying belt.

[0018] As a further independent invention, it can be provided that the leg board carries a replaceable leg pad. In particular, the leg board has a component for releasably fastening the leg pad. The device is in particular constructed in one piece with the leg board. Expediently, the leg board comprises a carrier plate, wherein the rigid edge of the leg pad is overlapped by the guide rails of the carrier plate and is thus held on the carrier plate. The user can easily insert the desired or purposeful leg pad on site. When changing users, the user can replace the existing leg pad with a personalized leg pad, in particular without the need for tools.

[0019] According to a further invention, in a carrying device comprising at least one back panel, at least one shoulder strap and a waist belt, the back panel is connected to the waist belt and / or the shoulder straps via an at least partially closable textile receiving bag. This makes it possible to replace damaged straps or to remove, clean and reattach dirty straps in a simple manner. In particular, this can be done without tools.

[0020] This type of connection between the back plate and the waist belt can be advantageously applied and used in a carrying system for carrying a battery on the back (back battery). The battery can thus be arranged expediently on the back plate. The battery can be designed in the form of a battery pack. The battery or the battery pack forms a load carried by the carrying system according to the invention, wherein the load (back plate with the battery pack) is supported, for example, on the waist belt by means of a textile receiving bag. The battery or the battery pack is used for operating the electric tool.

[0021] In another embodiment of the carrying system, a suspension for a tool (eg, an electric tool) can be provided on the back plate of the carrying system. It can also be advantageous if the tool is carried on a belt. The tool can also be held only by the user.

[0022] Advantageously, the textile receiving pocket is formed on the waist belt and / or shoulder strap, wherein a section of the back panel is held in the receiving pocket in an easily removable manner. For this purpose, it may be expedient for the back panel section held in the receiving pocket to be locked in the textile receiving pocket by means of, in particular, a textile tab.

[0023] Any desired combinations of the features and exemplary embodiments result in further advantageous exemplary embodiments and features according to the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Figures 1 to 9 1 shows a first embodiment of a carrying device 1 according to the invention, which is arranged for use with a brush cutter, a motorized sickle, a bush cutter or a similar tool 10, as shown in FIG. Figures 37 to 40 As schematically shown in .

[0065] according to Figures 1 to 9 The carrying device 1 shown in the embodiment of is essentially composed of a back panel 2, which comprises a base panel 12 and a drawer 22 which is held telescopically in the base panel. A ball joint 24 is arranged at the upper end 23 of the drawer 22, which carries a mounting plate 25. The mounting plate 25 is positioned in a receiving pocket 13 of the shoulder strap unit 14. The shoulder strap unit 14 has two shoulder straps 3 and 4, the rear ends 5 and 6 of which are connected to each other via the shoulder strap unit 14. The front ends 7 and 8 of the shoulder straps are fastened to the chest plate 9 in the embodiment.

[0066] The carrying strap 11 extends from the breast plate 9 downward to the leg plate 30 and from there laterally back to the base plate 12 of the back plate 2. The carrying strap 11 is preferably connected with one end 15 to the breast plate or expediently to a latch on the breast plate 9 in a length-adjustable manner; the other end 16 of the carrying strap 11 is (preferably) connected to the lower side section of the base plate 12 of the back plate 2 in a length-adjustable manner. The carrying strap 11 is fastened to the base plate 12, in particular, in the vicinity of its (first) longitudinal edge 17.

[0067] The side strap 20 is fastened in the region of the upper section of the base plate 12 to the second longitudinal edge 18 of the base plate 12, which is opposite the first longitudinal edge 17 of the base plate 12. The front end 21 of the side strap 20 is connected to the buckle 84 arranged on the carrier belt 11 via the connecting element 19. Figure 3 and Figure 4 Buckle 84 is enlarged in Figure 4 It is shown in FIG. 1 that it is movable on a carrier belt 11 .

[0068] In particular, the buckle 84 constitutes an independent invention, which is held on the carrying belt 11 between the leg plate 30 and the chest plate 9. The buckle 84 has a locked state and a released state. In the locked state, any movement of the buckle 84 along the longitudinal direction of the carrying belt 11 in the direction of the double arrow 85 is blocked. Preferably, the clamp 87 of the buckle 84 is self-locking in both directions of the double arrow 85. When the clamp 87 is in the released position, the buckle 84 together with the connecting element 19 (as the front end 21 of the side belt 20) can be continuously moved along the carrying belt 11.

[0069] The clamp 87 has in particular a spring element, not shown in detail, which holds the clamp 87 in the locked position. The spring element can in particular be designed as a leg spring. It is expedient for the spring element to be integrally formed with the clamp 87.

[0070] In this embodiment, the belt buckle 84 comprises two clamps 87, which have operating wings 92, 94 that can move in opposite directions to each other, wherein each of the operating wings 92, 94 acts on the clamp 87 so that the clamp blocks the movement in the direction of the carrier belt 11. In order to move the belt buckle 84 in the direction of the carrier belt 11, it is advantageous if at least one clamp 87 is operated by an operating wing 92 or 94. In particular, the two operating wings 92 and 94 can be unlocked together with one hand, so that the belt buckle 84 can be freely moved in both directions along the carrier belt 11. Figure 4 As shown, the two operating wings 92 and 94 move toward each other in the direction of arrows 91 and 93. This releases the clamping of one operating wing 92 and the carrier belt 11, and releases the clamping of the other operating wing 94 and the carrier belt 11. The pivot axes 95 of the operating wings 92, 94 are advantageously at an angle to each other. This facilitates the user's one-handed grip.

[0071] The belt buckle 84 has a receptacle 83 for the connecting element 19, which receptacle forms the end of the side strap 20. The connecting element 19 is held pivotably in the plane of the belt buckle 84 in the receptacle 83. The pivot axis 82 of the connecting element 19 in the receptacle 83 is perpendicular to the locking plate 86. The belt buckle 84 is arranged on the locking plate 86. The connection between the receptacle 83 and the connecting element 19 is advantageously implemented as a snap-on connection.

[0072] The buckle 84 can be moved along the carrier belt 11 with one hand and under load, i.e. without loosening or removing the carrier device 1 or its individual straps (e.g. the carrier belt 11 or the side straps 20). The buckle 84 can be moved on the carrier belt 11 in particular continuously and without releasing the connection between the side strap 20 and the carrier belt 11. The side strap 20 is therefore not separated from the carrier belt, but is merely moved along it to a different position. To move the side strap 20, the operating wings 92 and 94 are pivoted together toward each other in the direction of the arrows 91 and 93 by two fingers of the user. The unlocked buckle 84 can now be moved on the carrier belt 11 in the direction of the double arrow 82 according to the user's requirements. In this case, the connecting element 19 can be pivoted in the receptacle 83. The guidance of the side strap 20 is not hindered.

[0073] The front end 21 of the side strap 20 is always located below the breast plate 9. Since the side strap 20 is connected to the carrying strap 11 below the breast plate 9 and a portion of the force has been introduced into the back plate 2 through the side strap 20, the torsion of the breast plate 9 caused by the tension introduced into the breast plate 9 by the carrying strap 11 can be alleviated.

[0074] The longitudinal movement of the buckle 84 on the carrying belt 11 changes the force distribution between the shoulder belt 3 and the side belts 20. The user can use this to change the load acting on him from time to time. The one-handed operability of the buckle 84 enables the load distribution to be adjusted without disassembling the carrying belt 1 and in particular during work.

[0075] The lower end of the back panel 2 (in this embodiment, the lower end 26 of the base panel 12 ) carries a waist belt 27 which is locked by a front buckle 28 .

[0076] From the basis Figure 6 It can be seen from the rear view that a textile receiving pocket 29 is configured on the waist belt 27, in which the lower end 26 of the back plate 2 is received. Fig.28 It is shown how the end 26 of the back panel 2 is released from the textile receiving pocket 29. First, the tab 72 is released, which overlaps the end flange 71 of the end 26. Then, the lower end 26 of the back panel 2 can be pivoted out of the textile receiving pocket 29 in the direction of the arrow.

[0077] The assembly is then carried out in the reverse order, which will be described below. In particular, the releasable connection of the back panel 2 to the waist belt 27 (and to other elements of the carrying device 1) also constitutes an independent invention.

[0078] Different embodiments of leg panels 30 are described below, which have differently constructed belt channels 40 and differently functional fixing devices (Fixiervorrichtungen) 50 arranged between the support belt 11 and the leg panel 30. The described invention is not limited to the illustrated embodiments, but generally has leg panels with different belt channels. Here, the channels can be constructed, for example, integrally or separately, closed or interrupted on the support plate, and the channel cross section can be designed, in particular, flat or round. The support belt 11 is designed as a belt in the embodiment, but can also be designed as a rope or similar connecting element.

[0079] In a first embodiment, the leg plate 30 consists of a particularly rigid carrier plate 31 which carries a connecting unit 32. The connecting unit 32 is located at a distance x below the upper edge 33 of the carrier plate 31 (see Fig.37 ). A belt channel 40 is formed at the upper edge 33 of the carrier plate 31, and the belt channel has a channel center axis 41. The carrier belt 11 is guided through the belt channel 40 along the longitudinal direction of the channel center axis 41, wherein the carrier plate 30 is arranged to be movable on the carrier belt 11 in the direction of the double arrow 39.

[0080] The channel center axis 41 of the belt channel 40 can extend straight; advantageously, the channel center axis 41 is slightly curved into an arc shape. In particular, the direction of the channel center axis 41 is close to the direction of the carrier belt 11 in the leg plate 30 area.

[0081] Especially if Figure 2 , 6 As shown in FIG. 8 , the belt channel 40 is assembled from various channel segments 42a, 42b, and 42c in the first embodiment, and these channel segments are spaced apart from each other by a distance a in the direction of the channel center axis 41. The distance a is Figure 1 , 2 It is the same as in the embodiments shown in Figures 5 to 9; advantageously, the distance a between the channel sections 42a, 42b, 42c can be configured differently.

[0082] A carrying device 1 for carrying a hand-held tool 10 by a user, comprising at least one shoulder strap 3, 4 and a side leg plate 30 with a connecting unit 32 for fastening the tool 10, wherein it can be advantageous if the channel cross-sectional area 47 of the belt channel 40 of the leg plate 30 is designed to be at least 2 times, in particular 3 times, and at most 10 times the belt cross-sectional area 37, for example Fig.10 shown.

[0083] In a first embodiment, the belt channel 40 is formed by channel sections 42a, 42b, 42c in the form of belt loops 43. Advantageously, the belt loops 43 are made of metal and are held in the material of the leg plate 30. For this purpose, the carrier plate 31 preferably forms a thickened edge 33. The configuration of the belt loops 43 of the channel sections 42a, 42b, 42c is one of many possibilities. Alternatives for the configuration of the belt channel 40 will be given below in other embodiments. Regardless of the configuration of the belt channel 40, the advantages and features described can be transferred to all embodiments.

[0084] The leg plate 30 carries an especially flat leg pad 34 on its outer side 88 facing away from the connecting unit 32 for the tool 10 .

[0085] The rear plate 2 is designed such that the extension 22 and the base plate 12 are each produced as a one-piece injection-molded part.

[0086] As shown by user 99 (see Figures 37 to 40 ) The carrying device 1 for carrying a hand tool 10 is arranged such that the shoulder straps 3, 4 are placed on the shoulders of the user 99 for wearing the carrying device 1. The leg panels 30 are held on the carrying device 1 by means of the carrying straps 11, wherein one end 15 of the carrying straps 11 is operatively connected to the shoulder straps 3 and 4. In the embodiment shown, this operative connection is ensured by the chest plate 9, wherein the front ends 7, 8 of the shoulder straps 3, 4 are fixed to the base of the chest plate 9, while the ends 15 of the carrying straps 11 are connected to the chest plate 9 in the lower region of the chest plate 9 (preferably by a releasable plug connection).

[0087] The carrier tape 11 is guided through the tape channel 40, wherein the channel sections 42a, 42b and 42c, preferably formed by the tape loops 43, are spaced apart from one another by a distance a. Thus, a free space 44 is formed between the channel sections 42a, 42b and 42c, in which the carrier tape 11 is not guided.

[0088] Fig.10 The belt loop 43 of the channel section 42a is schematically shown. The center 45 is located on one side of the plane 35 of the carrier plate 31, wherein the plane 35 is designed to be slightly curved in the circumferential direction of the leg plate 30. The center 45 is located on the side of the plane 35, on which the connecting unit 32 is also located. Advantageously, the maximum width B of the belt channel 40 corresponds to at least twice the belt width divided by π. Advantageously, the carrier belt 11 has a belt cross-sectional shape with a polygonal profile. A suitable cross-sectional shape of the carrier belt 11 is a rectangle.

[0089] If gravity follows Fig.10If the load is directed in the direction of the arrow 38 of the support plate 30, the weight is directed into the support belt 11 via the belt loop 43, and the support belt rests on the arch of the belt loop 43 due to its flexibility. In the loaded state, the support belt 11 is essentially located on the side of the support leg pad 34 of the plane 35 of the support plate 31.

[0090] Figures 11 to 16 Another embodiment of the leg plate 30 is shown in FIG. 1 and will be described in detail below.

[0091] The basic structure of the leg plate corresponds to Figure 1 , 2 5 to 9, differs from the leg plate 30 in another embodiment with a channel 40. The leg plate 30 generally consists of a particularly rigid carrier plate 31 with an upper edge 33. Fig.15 and 16 As shown, the upper edge 33 is thickened. The inner side of the carrier plate 31 faces the user 99 , while the outer side 88 faces away from the user. The connecting unit 32 is located on the outer side 88 of the carrier plate 31 facing the tool 10 .

[0092] A particularly flat leg support 34 is arranged on the (inner) side of the carrier plate 31 facing away from the connecting unit 32 .

[0093] As especially Fig.11 As shown, the belt channel 40 extends at the upper edge 33 of the leg plate 30. The belt channel 40 has an opening on its lower side. The inner longitudinal side of the belt channel 40 facing the user is closed by an end cap 110. In the belt channel 40, the support belt 11 (see FIG. 1 ) configured as a flat belt is inserted. Fig.13 ) is guided to a roller 111 movably supported in the belt channel 40. The end cap 110 serves as an inner support for the roller 111.

The tongue 112 is connected to the connecting unit 32. The end cover 110 is particularly made of metal.

[0094] As a particularly independent invention, Fig.12 and 13 It is shown in the figure that it is advantageous that the leg pad 34 is replaceably held on the leg plate 30. In particular, the leg plate 30 has a component for releasably fastening the leg pad 34. This component is particularly constructed in one piece with the carrier plate 31 of the leg plate 30.

[0095] In particular, it is provided that the leg plate 30 has a guide rail 115 at the edge, which serves as a component for releasably fastening the leg pad 34. The guide rail 115 overlaps the rigid edge 116 of the leg pad 34 and holds it on the carrier plate 31. Preferably, the leg pad 30 is arranged in the direction of the arrow 97 (see Fig.12) is inserted between the guide rails 115 parallel to the leg panel 30. The inner side of the leg panel 30 and the guide rails 115 form a receiving pocket for the leg pad 34. The leg pad 34 is thus replaceable and can be designed in a particularly advantageous manner according to the wishes and requirements of the user.

[0096] The guide rail 115 is constructed in one piece with the leg plate 30. The guide rail 115 has an L-shaped cross section, with which it protrudes from the plane of the leg plate 30 and engages behind the leg pad 34. Like the guide rail 115, the carrier plate 34 of the leg plate 30 has an opening.

[0097] Advantageously, a plurality of guide rails 115 are provided, wherein the guide rails 115 extend along the periphery of the carrier plate 34 of the leg plate 30. Advantageously, the guide rails 115 are spaced apart from one another in the circumferential direction. It can be provided that the guide rails 115 are at different distances from the periphery of the leg plate 30. It is also possible to adjust the length of the guide rails 115 or the ratio between the length and the distance of adjacent guide rails 115.

[0098] The leg plate 30 is held on the carrier belt 11, which is arranged according to Fig.17 In an embodiment of the invention, the ends of the leg plate 30 can be connected to a simple shoulder strap. The shoulder strap can be placed across the shoulders of the user 99. The leg plate 30 can be moved on the carrying belt 11 in the direction of the double arrow 39 (when the positioning device 50 is released).

[0099] like Fig.17 As shown, the positioning device 50 is held on the carrier tape 11 and comprises a positioning element 59 which is fixed directly on the carrier tape 11 .

[0100] In accordance with Fig.17 In the embodiment of the present invention, the positioning element 59 is arranged outside the belt channel 40 at the first end or the second end of the belt channel 40, respectively. Therefore, in one direction of the double arrow 39, one end of the belt channel 40 abuts the positioning element 59; in the other direction of the double arrow 39, the other end of the belt channel 40 abuts the positioning element 59, thereby preventing the longitudinal mobility of the leg plate 30 on the carrying belt 11. The positioning device 50 is in the locked position 200.

[0101] The positioning element 59 held on the carrier tape 11 can be a clip, a brake or the like. Appropriately, the positioning element 59 can also engage in a form-fitting manner in the locking position 200 in the carrier tape 11, for example penetrate the carrier tape 11.

The positioning element 57 designed as a clip 62 is located above the belt loop 43, so that the carrier belt 11 has an increased included angle 56 around the belt loop 43. This increased included angle 56 and the sharp deflection of the carrier belt 11 in the area of ​​the clip 62 prevent the belt loop 43 received in the included angle 56 from moving in the direction of the double arrow 39. Except for any slight play, the leg plate 30 is held on the carrier belt 11 in an immovable manner in the direction of the double arrow 39.

[0104] In accordance with Fig. 22 and 23 In the embodiment of the present invention, the positioning device 50 is held on the leg plate 30. One of the channel sections 42a, 42b, 42c of the open belt channel 40 is configured as the positioning device 50, in this embodiment, the open belt channel 40 The channel section 42a. Fig.23As shown, the belt loop 43 of the channel section 42a forms the positioning element 58 of the positioning device 50. The belt loop 43 is displaced into the belt channel cross section in the direction of the arrow 60 as a movable positioning element 58. The positioning is achieved by narrowing the belt channel. Therefore, the positioning element 58 of the positioning device 50 is formed by the channel section 42a or the belt loop 43, which can be displaced relative to the channel center axis 41. As a result, the carrier belt 11 is clamped between the belt loop 43 and the bottom of the belt channel 40, which corresponds to the locking position 200 of the positioning device 50. In the locking position 200 of the positioning device 50, the displacement force required to displace the leg plate 30 on the carrier belt 11 is significantly higher, in particular several times higher than the force required for displacement in the release position 100 of the positioning device 50. In the belt channel 40 comprising the channel sections 42a, 42b, 42c, the positioning device 50 is advantageously designed as a channel section 42a that can be displaced relative to the channel center axis 41.

[0105] In accordance with Fig.24 and 25 In the embodiment of the present invention, the positioning device 50 is configured as a clevis 61 held on the leg plate 30. The clevis 61 is located on the outer side 88 of the load-bearing connection unit 32 of the load-bearing plate 31. The clevis 61 is transverse to the channel center axis 41 and has a lateral distance s relative to the belt channel 40. Fig.25 As shown, the horn 61 includes three clamping posts 61a, 61b, 61c, between which the carrying belt 11 passes. The carrying belt 11 diverted by the belt channel 40 through the horn 61 (especially through multiple deflections between the clamping posts 61a, 61b and 61c) is frictionally locked and the leg plate 30 is immovably positioned on the carrying belt 11.

[0106] In accordance with Fig.26 and 27 In the embodiment of the present invention, the positioning element 63 of the positioning device 50 is configured as a clamping slide (see Fig. 27 ). In the illustrated release position 100 , the carrier belt 11 guided by the belt channel 40 which is closed along its length can move freely; the leg plate 30 can move on the carrier belt 11 .

[0107] If the slide 64 placed in the edge 33 of the leg plate 30 is moved in the arrow direction 65, the positioning element 63 configured as a clamping block is displaced in the belt channel 40 closed along its length in the arrow direction 66 and clamps the support belt 11 extending in the belt channel 40. Fig. 27 The positioning device 50 is in its clamping position 200 .

[0108] Fig.28 shows how to move the lower end 26 of the back plate 2 from Figure 629 of the waist belt 27. First, the tab 72 is released, which overlaps the end flange 71 of the end 26. The lower end 26 of the back panel 2 can then be pivoted out of the textile receiving pocket 29 in the direction of the arrow 98. The connection of the belt of the carrying device 1 to the back panel 2 via the textile receiving pockets 13, 29 is to be understood as both an extension of the above-described invention and an independent inventive concept.

[0109] This type of connection between the back panel 2 and the waist belt 27 can be advantageously adapted and used in a carrying system for carrying an AP battery (back battery) on the back. The AP battery can thus be arranged on the base plate 12 of the back panel 2 in a targeted manner. The AP battery can be designed in the form of a battery pack. The AP battery or the battery pack constitutes a load carried by the carrying device 1 according to the invention, wherein the load (back panel with the battery pack) is supported, for example, on the waist belt 27 by means of a textile receiving bag 29. The AP battery or the battery pack is used in particular for the operation of an electric tool.

[0110] In another embodiment of the carrying device 1, a suspension for a tool, for example a suspension for an electric tool driven by an AP battery, can be provided on the back plate 2 or its base plate 12. It can also be advantageous if the belt 27 itself carries the tool. The tool can also be held only by the user.

[0111] Regardless of whether the tool is connected to the carrying device 1 and / or the back plate 2, the way in which the AP battery fastened to the base plate 12 of the carrying device 1 is fastened to the waist belt 27 by means of the textile receiving bag 29 constitutes an independent inventive basic concept.

[0112] exist Figures 29A to 29C , the independent inventive concept is further schematically shown, which in one embodiment is embodied as a releasable connection between the lower end 26 of the back panel 2 and the textile receiving pocket 29 of the waist belt 27. In general, the invention relates to the connection of a dimensionally stable element of a back support system with a textile element. In the illustrated embodiment, the back panel of the support device 1 is connected to the belt of the support device 1 via a closable textile receiving pocket 13, 29.

[0113] For example, the textile receiving pocket 29 has an opening 69 extending from the outer edge 67 of the receiving pocket 29 to the fold 68. The end 26 of the back panel 2 has a substantially T-shaped configuration and has end flanges 70, 71. In order to connect the lower end 26 of the back panel 2 to the waist belt 27, the lower end flange 70 in the direction of its extension is inserted into the receiving pocket 29 and engages behind the fold 68. Now, as shown in FIG. Fig.29B As shown, the entire T-shaped end 26 of the back panel 2 is pushed into the receiving pocket 29, wherein the longer end flange 71 slightly protrudes from the opening 69 of the receiving pocket 29. Fig.29BThe waist belt 27 is fixedly connected to the back panel 2 in such a way that the tab 72 fastened to the waist belt 27 covers the protruding end of the end flange 71 and is fixedly connected to the outside of the receiving pocket 29, for example by means of Velcro. When the receiving pocket 29 is closed, the protruding end of the end flange 71 is pressed into the receiving pocket 29, thereby minimizing the longitudinal play of the connection. Instead of an asymmetrical design of the end flange, the receiving pocket 29 can also be designed asymmetrically. The waist belt 27 is fixedly connected to the back panel 2, wherein the load to be applied presses the end 26 of the back panel 2 into the receiving pocket 29 in the direction of the arrow 73. A load-transmitting connection is ensured.

[0114] The upper end 23 of the back plate 2, in this embodiment the upper end 23 of the drawer 22, carries a mounting plate 25 which is arranged in accordance with Fig. 30A The receiving pocket 13 of the shoulder strap unit 14 is constructed corresponding to the mounting plate 25, wherein, as shown in FIG. Fig. 30B As shown, the mounting plate 25 is inserted into the receiving pocket 13 of the shoulder strap unit 14. The leg ends 74 of the U-shaped mounting plate 25 protrude from the opening 75 of the receiving pocket 13 and are positioned by flexible tabs 76, which are fastened to the shoulder strap unit 14. The flexible tabs 76 are folded over the leg ends 74 and fixed to the outside of the receiving pocket 13.

[0115] This can be achieved by means of Velcro or similar, in particular releasable, closures, such as Fig. 30C Expediently, the tabs 76 wrap around the leg ends 74 so that the mounting plate 25 is pressed into the receiving pocket 13 by folding and fixing the tabs 76 and thus the longitudinal play of the connection is minimized.

[0116] In order to clean or replace the textile components of the carrier device 1, the receiving bag 13, 29 can be opened and the rigid components can be removed. In this way, the cushion can be washed separately from the hardware of the carrier device 1, for example in a washing machine.

[0117] The upper end 23 of the back plate 2, i.e., the end 23 of the extraction portion 22, is Fig.31 The mounting plate 25 is connected by a ball joint 77. Fig.32 and 33 As shown in the schematic diagram of , the mounting plate 25 can be pivoted in all spatial directions. Therefore, the back plate 2 is articulated with the shoulder strap unit 14. The user 99 can move without being hindered by the carrying device 1.

[0118] In order to hold the shoulder strap unit 14 in a defined starting position relative to the back plate 2, a spring element 78 is provided which engages on both sides of the ball joint 77 on the shoulder strap unit 14 and is connected to the back plate 2. Figures 34 to 36 In the embodiment shown, the spring element 78 acts between the end 23 of the drawer 22 of the back plate 2 and the shoulder strap unit 14 .

[0119] The spring member 78 is preferably an elastic band 79 or the like, such as Fig.35 and 36 As shown, the spring member extends upward from a point below the ball joint 77 to the shoulder strap unit 14. Fig.35 As shown, the spring elements 78 are located symmetrically to the left and right of the ball joint 77 in order to ensure a neutral, in particular symmetrical, orientation of the shoulder strap unit 14 relative to the back panel 2 in the unloaded state.

[0120] The above-mentioned positioning device 50 for fixing the leg plate 30 on the carrying belt 11 is used according to the work application or the user's desire. Figures 37 to 40 1 shows a user 99 who uses the carrying device 1 according to the invention to carry a tool 10 designed as a brush cutter. The guide rod 101 of the tool 10 is held on the leg plate 30 by means of a connecting unit 32. The connecting unit 32 is located at a distance x below the upper edge 33 of the leg plate 30. The guide rod 101 carries a tool head 102 with a tool 103 at the (lower) end; a drive unit 104 is arranged at the other end of the guide rod 101, which can be a drive motor or a battery pack for an electric motor arranged in the tool head 102.

[0121] The user 99 supports the tool 10 on the carrying device 1. The tool 10 is guided by means of the handle 105 shown in this embodiment.
