Description

Technical Field

[0001] The utility model relates to a carrying device for hand-guided gardening and / or forestry working tools. Background Art

[0002] A carrying device for a brush cutter is known from the prior art JP 2005-058064 A. The carrying device comprises two suspension belts extending in a V-shape between the shoulder belts. Each of the suspension belts is formed by a belt loop, the upper end of which is suspended at the loop of the shoulder belt and the lower end is suspended at the loop of the brush cutter. In this way, the brush cutter is held at the carrying device. Buckles for changing the length of the suspension belts are provided on the suspension belts accordingly. By increasing or reducing the length of the suspension belts, the distance between the work tool and the carrying device can be adapted to the body size and / or work task of the user of the carrying device. Due to the presence of two separate suspension belts, the length adjustment is cumbersome because the two suspension belts must be adjusted in length respectively. In order to arrange the work tool centrally between the shoulder belts even after the length adjustment, the two suspension belts are extended or shortened by the same amount. This requires a lot of skill because after adjusting the first suspension belt, the weight of the work tool only acts on the shorter of the two suspension belts and thus pulls the relevant shoulder belt forward. This makes it difficult to estimate the length of the additional suspension straps. A further disadvantage of the known design is that the movement space of the work tool arranged on the support device is reduced. The two lower ends of the suspension straps are connected to the work tool, so that the work tool cannot be moved along the length of the suspension straps. In addition, due to the loop-shaped design of the two suspension straps, twice the number of suspension straps is required, which has a negative impact on the manufacturing costs and weight of the support device. Utility Model Content

[0003] The object is therefore to provide a support device with an improved length adjustment. In addition, the object is to reduce the material consumption.

[0004] The utility model relates to a carrying device for hand-guided gardening and / or forestry tools, in particular motor-driven gardening and / or forestry tools, the carrying device having a carrying tool for being worn on a user of the carrying device, the carrying tool comprising two shoulder straps; and having a suspension belt, in particular a rubber elastic one, which is held at a first connection point on the carrying tool, wherein the gardening and / or forestry tools can be connected to the suspension belt. According to the utility model, the suspension belt is held at a second connection point on the carrying tool, wherein the length of the suspension belt is between the first connection point and the second connection point, and furthermore, the second connection point is formed by an adjustment device, wherein the adjustment device is set up for fixing the suspension belt in a force-locking manner, so that the length of the suspension belt can be adjusted when the force-locking fixing is cancelled. In addition, the utility model relates to an adjustment device for the carrying device according to the utility model, the adjustment device comprising a base body, a belt inlet, a belt outlet and at least one clamping body arranged between the belt inlet and the belt outlet, which can move relative to the base body.

[0005] In particular, products that are mainly composed of textile components are called carrying devices, which can be worn by the user in order to fasten heavy objects, such as hand-guided gardening and / or forestry tools, to the product. Therefore, the carrying device can make the transportation and / or use of the working tool easier by: the weight and / or operating force of at least a part of the working tool is taken up by the carrying device and transmitted to the body of the load. The carrying device is fixed / can be fixed to the user's body by a carrying tool including at least two shoulder straps. A chest belt can extend between the shoulder straps. In addition, the carrying tool can include a waist belt and / or a backboard. Here, the backboard can be formed in particular by a plastic component. As an alternative to the backboard, a back part composed of textiles and / or pressed foam can also be provided. The heavy object to be carried is connected to the carrying tool via a suspension belt. In this case, the working tool can be indirectly connected to the suspension belt via a loop, a spring hook or a similar connecting device. Alternatively, the working tool directly contacts the suspension belt and is therefore connected to the suspension belt. The suspension belt can be configured as a flat belt with a substantially flat cross section, or as a round belt with a round, square or similarly shaped cross section. The suspension belt is held at a first connection point and a second connection point on the carrying tool. At the first connection point, the suspension belt is indirectly or directly connected to the carrying tool. The first connection point is particularly arranged at the first shoulder strap or at the first end of the chest strap. The suspension belt is particularly held at the first connection point in a form-fitting manner. In particular, the end of the suspension belt opposite to the free end is held at the first connection point in a form-fitting manner. The second connection point is particularly arranged on the second shoulder strap or at the second end of the chest strap. A suspension belt with a certain length extends between the connection points. Here, the length is measured along the longitudinal direction of the suspension belt and in an unloaded state, that is, when no weight is arranged on the suspension belt.

[0006] An adjustment device is arranged at the second connection point, by means of which the length of the suspension belt can be adjusted, that is, reduced or increased. The suspension belt is held at / in the adjustment device in a force-locking manner. By reducing or cancelling the force-locking, the fixing can be released and the suspension belt can be moved relative to the carrier at the second connection point, thereby adjusting the length of the suspension belt between the connection points. The suspension belt is held at the carrier by the adjustment device. It can be provided that the suspension belt is rubber-elastic. In the case of a tensile force of 50N to 130N, in particular in the case of a tensile force of 70N to 100N, the rubber-elastic suspension belt is in particular stretched by 100%, that is to say the length of the suspension belt is doubled. The rubber elasticity of the suspension belt is in particular selected so that the weight of the work tool to be connected is less than the tensile force in the case of a strain of 100%. The weight of the hand-guided gardening and / or forestry work tool is in particular less than 10 kg, in particular between 2 kg and 8 kg. Therefore, the weight of the work tool does not use up the maximum elastic strain of the rubber-elastic suspension belt, in particular at least 150% to 250%. The rubber-elastic extensibility of the suspension belt can be used to elastically change the length. With this work tool, it is possible to reach objects that are farther away without having to adjust the length at the adjustment device. In this case, the user can easily push the work tool away from himself against the restoring force of the suspension belt. The tensile force required for the absolute elastic length change also depends on how long the suspension belt length is between the connection points. If this length is already relatively large, only a small tensile force is required. Therefore, even if the suspension belt is rubber-elastic, there is a need for length adjustment, so that the tensile force can be minimized in a dynamic working mode.

[0007] Since the suspension belt extends from the first connection point to the second connection point and the adjustment device is arranged at the second connection point, the length of the suspension belt can be easily adjusted by a single adjustment device. It is sufficient for the suspension belt to extend between the connection points in a single layer, thereby requiring less material investment.

[0008] In one embodiment, the suspension belt has no obstructions at least over a portion of its length, so that the connection of the gardening and / or forestry tool to the suspension belt can be moved along this length portion. In this way, the position of the connection can be readjusted, in particular automatically, when the length is adjusted. When the length is shortened or extended (other conditions remain unchanged), the position of the connection should be moved by half of the adjustment length, so that the weight of the tool acts evenly on both connection points, in particular on both shoulder straps or chest straps. In order to enable the connection to be moved automatically, the suspension belt has no obstructions that hinder the movement. Such obstructions are in particular thickness jumps, such as knots, in the suspension belt that would hinder the sliding of the tool along the edge. The suspension belt has a consistent cross section in the unobstructed length portion and has no interruptions or separations. The minimum length of the suspension belt between the connection points is in particular between 20 cm and 40 cm, in particular about 30 cm, in the unloaded state. The maximum length between the connection points is in particular between 50 cm and 100 cm, in particular about 70 cm, in the unloaded state. The unobstructed length portion is at least 10 cm, in particular greater than 15 cm, and particularly greater than 20 cm. The suspension belt extends unobstructed over the entire length, in particular between the connection points. In addition, the unobstructed length portion allows the user to move the work tool back and forth along the suspension belt during dynamic work. In this way, the movement space of the work tool arranged on the support device can be increased compared to the prior art.

[0009] In one embodiment, the adjustment device has a belt inlet and a belt outlet, and the free end of the suspension belt extends from the belt outlet. When the length of the suspension belt increases, the free end of the suspension belt shortens. When the length of the suspension belt decreases, the free end of the suspension belt lengthens. When adjusting the length, the suspension belt moves relative to the adjustment device. When reducing the length, the section of the suspension belt between the connection points moves into the adjustment device through the belt inlet. For this reason, the section of the suspension belt that moves into the belt inlet has no obstruction that would hinder entry into the adjustment device. When increasing the length, the section of the suspension belt located at the free end moves into the adjustment device through the belt outlet. In particular, 3 cm to 15 cm, and particularly in particular 5 cm to 10 cm of the suspension belt are in the adjustment device, i.e., between the belt inlet and the belt outlet.

[0010] The length of the suspension strap can be adjusted in an especially stepless manner. At the maximum set length, the free end is still in particular longer than 1 cm, in particular longer than 3 cm, in particular longer than 10 cm, so that the user's fingers can still grasp it. A thickening can be provided at the free end of the suspension strap. This thickening prevents the free end from entering the adjustment device through the strap outlet during adjustment. In addition, the thickening can also serve as a form-fitting gripping area for the user, at which the user can grasp the suspension strap particularly advantageously (compared to the unobstructed area of ​​the suspension strap) in order to apply a tensile force at the free end.

[0011] In one embodiment, the suspension belt is fixed between the belt inlet and the belt outlet by means of a clamping body. In one embodiment, the adjustment device is configured to press the suspension belt onto the base body of the adjustment device and / or another clamping body by means of a clamping body for force-locking fixation. The clamping body is movably, in particular pivotably, supported at the base body of the adjustment device. The clamping body is in particular spring-prestressed onto the base body. In this way, the clamping body applies a pressing force to the section of the suspension belt between the clamping body and the base body. It is also possible to provide two or more clamping bodies between which the suspension belt extends and on which the clamping bodies apply a pressing force.

[0012] In one embodiment, the force-locking fixation, in particular the compressive force acting on the suspension belt, can be released by operating the operating element of the clamping body and / or by the pulling force applied to the free end of the suspension belt. Whether it is used to increase or reduce the length, it is not necessary to lighten the suspension belt in advance. The length of the suspension belt between the connection points can be adjusted with one hand. For reducing the length, it is only necessary to pull at the free end of the suspension belt. For increasing the length, it is only necessary to operate the operating element, so that the weight of the work tool automatically pulls the suspension belt out of the adjustment device. By operating the adjustment device with one hand, the length can be adapted to the working conditions at any time without interrupting the work. As a result, the user can react spontaneously and quickly and easily adapt the length of the suspension belt to the situation or the work task. This promotes ergonomics and efficiency when working with the work tool arranged at the carrying device.

[0013] In one embodiment, the force-locking fixation, in particular the pressing force acting on the suspension belt, is enhanced under the action of the weight of the work tool connected to the suspension belt between the first connection point and the second connection point. In this way, the suspension belt is always clamped sufficiently strongly by the adjustment device without the user having to set and / or readjust something. In one embodiment, the clamping body can be pivoted about the clamping axis relative to the base body of the adjustment device, and the clamping axis is eccentric to the clamping surface of the clamping body. The clamping body can be pivoted in the release direction and in the opposite locking direction. When pivoting in the release direction, the distance between the clamping surface and the suspension belt increases. When pivoting in the locking direction, the distance between the clamping surface and the suspension belt decreases. The spring arranged between the clamping body and the base body preloads the clamping body in the locking direction. The clamping body can be loosened or lifted from the suspension belt by the release torque acting in the release direction, so that the suspension belt can be moved relative to the base body and the length can therefore be adjusted. The release moment can optionally be applied by an actuating force on the actuating element in the release direction and / or by a tensile force on the free end of the suspension strap.

[0014] In one embodiment, the adjustment device has a fastening axis, which is connected or can be connected, in particular can be connected without tools, to the carrying tool, in particular to the shoulder belt, in a manner that can be pivoted about this fastening axis. The fastening axis extends in particular transversely to the longitudinal direction of the shoulder belt and parallel to the surface of the shoulder belt. As a result, the adjustment device can follow the suspension belt during movements at head height and / or above head height without the suspension belt being deflected sharply at the belt inlet of the adjustment device. In this way, even in this state, the length can still be easily adjusted and the wear of the suspension belt at the belt inlet is reduced. This is particularly advantageous in carrying devices for gardening / forestry work tools, which are used to work on high hedges, tree crowns or the like at and above the head height of the user.

[0015] By arranging the adjustment device at the second connection point, in particular at the shoulder strap, the adjustment device is always accessible to the user at the same location on the carrying device, regardless of the suspension strap length or offset set at the time. The user can thus grasp the operating element and / or the free end in a targeted manner, in particular without having to look over, and make a length adjustment. In order to adapt the carrying device to different body sizes and / or working situations, it can be provided that alternative suspension positions for the fastening axis of the adjustment device are provided on the shoulder strap, which are spaced apart from one another in the longitudinal direction of the shoulder strap.

[0026] Figure 1 An embodiment of a support device 1 is shown for a schematically shown work tool 70, for example a pruning tool. The pruning tool is a motor-driven forestry work tool for pruning work. The work tool 70 has a front end 71 with a tool head, a rear end 72 with a housing for accommodating an energy source and a drive motor, and a guide tube 73 extending between them. The drive motor can also be arranged in the tool head or in the guide tube 73. Other gardening or forestry work tools, such as high-rise pruners, hedge shears, special harvesters or similar tools, can also be arranged on the support device 1.

[0027] The carrying device 1 comprises a carrying tool 10, which is worn on a user not shown by two shoulder straps 11, 12 and a waist belt 14. A back plate 15 extends between the shoulder straps 11, 12 and the waist belt 14, which back plate is adjustable in length in this embodiment. The suspension belt extends in front of the abdomen of the user and between the shoulder straps 11, 12. The suspension belt is configured as a rope 20 with a round cross section and rubber elasticity in this embodiment. The rope 20 has a thickening 26 in the form of a node at its first end. From the user's perspective, at the shoulder strap 11 on the right, a retaining buckle 50 is connected to the shoulder strap 11. The rope 20 is retained at the retaining buckle 50 by the thickening 26 in a form-fitting manner. The retaining buckle 50 will be described in detail later. An adjustment device 30 is fastened at the shoulder strap 12 on the left, through which the rope 20 extends, and the rope 20 is retained at the carrying tool 10 by the adjustment device. From the user's perspective, in front of the shoulder strap 12 on the left, the second end of the rope 20 hangs downward as a free end 27. The retaining buckle 50 forms the first connection point 21 of the rope 20. The adjusting device 30 forms the second connection point 22 of the rope 20. The length 23 of the rope 20 is located between the retaining buckle 50 and the adjusting device 30, and can be increased or decreased according to the needs of the user. In this embodiment, the length 23 is about 30 cm in the case of the minimum length setting and about 65 cm in the case of the maximum length setting. Due to the rubber elasticity of the suspension belt, the length 23 is about 40 cm in the case of the minimum length setting or about 80 cm in the case of the maximum length setting when the weight of the work tool is loaded. In order to reduce the length 23, the user uses a pulling force F Z The free end 27 of the cable 20 is pulled. To increase the length 23, the user manipulates the operating element 43 of the adjustment device 30 in the release direction 81. The length of the free end is greater than 20 cm in this embodiment. In order to arrange the work tool 70 on the carrying device 1, a spring hook 60 is engaged in the loop of the work tool 70, wherein the spring hook 60 is suspended or can be suspended on the cable 20. The spring hook 60 can slide back and forth along the cable 20 in this embodiment. The spring hook 60 forms the connection point of the cable 20 to the work tool 70. In this embodiment, since there are no obstructions along the length 23 that would prevent the sliding along, the spring hook 60 can slide along between the connection points 21, 22 over the entire length 23. In this way, the work tool 70 is reliably and nevertheless flexibly connected to the cable 20. In an alternative embodiment not shown, the guide tube of the work tool 70 can also be supported directly on the cable 20 and slide along continuously with its circumference over the length 23 of the cable 20. The section of the guide tube which is placed on the cable 20 forms the connection point between the work tool 70 and the cable 20 .

[0028] Figures 2 to 6 Shown in detail Figure 1The adjustment device 30 has a rear side 36 facing the carrier 10 and a front side 37 facing away from the carrier 10 ( Figure 4 The adjusting device 30 comprises: a belt inlet 31, at which the rope 20 enters the adjusting device 30; a clamping area 40, at which the rope 20 is fixed to the adjusting device 30; a turning area 46, at which the rope 20 turns; a belt outlet 32, at which the free end 27 of the rope 20 comes out of the adjusting device 30; and a fastening area 48, by which the adjusting device 30 is fastened to the carrier 10.

[0029] The fastening region 48 is arranged at the rear side 36 of the adjusting device 30, in particular at the upper end of the base body 33 of the adjusting device 30. Two fastening arms 49 extend from the base body 33 in a hook-like manner. The fastening arms 49 have a common fastening axis 95. The adjusting device 30 is fastened to the shoulder belt 12 only by means of the fastening arms 49, so that the base body 33 of the adjusting device 30 can be pivoted relative to the shoulder belt 12 about the fastening axis 95 of the fastening arms 49. The fastening arms 49 are suspended in corresponding tabs 13 at the carrying tool 10 (here at the shoulder belt 12) without tools. A plurality of tabs 13 ( Figure 1 ) enables suspension at different positions. The fastening axis 95 extends transversely to the longitudinal direction 97 of the shoulder strap 12 and parallel to the surface 98 of the shoulder strap 12. The fastening area 48 is bent from the plane of the rear side 36 toward the carrying tool 10. In this way, the lower end of the base body 33 does not protrude from the shoulder strap 12 or protrudes only slightly ( Figure 4 ). Instead of two fastening arms 49, only one fastening arm 49 can also be provided. The adjustment device 30 can also be connected to the carrier tool 10 in other ways and manners known to those skilled in the art.

[0030] The belt inlet 31 is arranged at the lower end of the adjustment device 30 between the front side 37 and the rear side 36 and is formed by the lower area of ​​the base 33. The rope 20 enters the base 33 from below or obliquely below along the entry direction 92 parallel to the rear side 36. Figure 3 As schematically shown in FIG. 2 , according to the set length 23 of the rope 20 and the sag formed by the rope 20, the entry direction 92 of the rope 20 changes between an entry direction 92′ from below and an entry direction 92 obliquely below from the right (from the user's perspective).

[0031] The belt inlet 31 is followed by the clamping region 40. In this exemplary embodiment, the base body 33 has a U-shaped configuration in the clamping region 40. Between the arms of the "U", the clamping body 41, which is designed as an eccentric cam, is supported on the base body 33 in a manner that allows it to pivot about the clamping axis 84. The spacing a between the clamping surface 42 formed at the periphery of the clamping body 41 and the base of the "U" varies from 0.01 to 0.10 depending on the pivot angle α of the clamping body 41. Figure 5 The maximum spacing a max Change to Figure 6 The minimum spacing a min The clamping body 41 is preloaded by the spring 44 in the locking direction 82, that is, preloaded to the minimum spacing ( Figure 6 ). The spring 44 is designed as a torsion spring and is suspended with its legs on the base 33 and the clamping body 41. The stop limits the movement of the clamping body 41 relative to the base 33 in the release direction 81. Since the diameter d of the rope 20 is greater than the minimum spacing a min , so that the clamping body 41 has already applied the pressing force F without the working tool 70 being arranged on the supporting device 1 P The spring force presses the clamping element toward the cable 20, so that the cable 20 is held in the adjustment device 30 in a force-locking manner. The diameter d of the cable 20 is 5 mm to 10 mm, in the exemplary embodiment 8 mm, and is therefore larger than the minimum spacing a. min The minimum distance is many times greater, in this embodiment being approximately 1.5 mm. The weight and / or operating forces pressing on the cable strands during use of the support device 1 generate a tensile force F G This results in a locking torque acting on the clamping body 41 which acts in the locking direction 82 and increases the contact pressure force F P In order to ensure that the clamping is equally durable over the entire adjustment range of the length adjustment, the clamping axis 84 is transverse to the rear side 36 of the adjustment device 30, in particular at right angles thereto. In this way, the tensile force F generated by gravity and / or operating forces on the rope strand is constant regardless of the specific entry angle. GAn enhanced locking torque around the clamping axis 84 is always caused on the clamping body 41. An operating element 43 is arranged on the clamping body 41, by which the user can pivot the clamping body 41 in the release direction 81 against the spring force. The operating element 43 is opposite to the clamping surface 42. The operating element 43 extends radially from the periphery of the clamping body 41. In this embodiment, the operating element 43 faces the first connection point 21. The base body 33 has a gripping recess 35 on its outer side facing away from the first connection point 21. The gripping recess 35 makes it easy for the user to resist holding (gegenhalten) the base body 33 when operating the operating element 43. The positions of the adjustment device 30 and the retaining buckle 50 can also be exchanged with each other. It can be provided that a mirror-opposite variant of the adjustment device 30 is set.

[0032] The clamping area 40 is followed by the deflection area 46 of the adjustment device 30. A trunnion-shaped deflection element 47 is arranged rotationally fixed at the base body 33, and the deflection element is particularly constructed integrally with the base body. The rope 20 is placed on the outer circumference of the deflection element 47, and the deflection element 47 deflects the rope 20 by more than 90°. The friction between the deflection element 47 and the rope 20 acts as a brake, so that the rope 20 is pulled through the adjustment device 30 in a braked manner when the clamping element is lifted. This allows the length 23 to be adjusted in a fine quantitative manner. In addition, the deflection element 47 deflects the rope 20 in the adjustment device 30, so that the rope does not continue to extend upward in the base body 33, but comes out of the belt outlet 32 ​​pointing downward. The rope 20 is centered on the deflection element 47 by the concave shape of the circumference of the deflection element 47. In this way, the rope 20 that initially hits the deflection element 47 eccentrically is centered before it passes through the belt outlet 32. As a result, the free end 27 of the rope 20 can be grasped more easily. Since the axis 87 of the deflection element 47 is transverse to the clamping axis 84, in particular at a right angle thereto, the belt outlet 32 ​​can be arranged on the front side 37. The section of the cable 20 entering the adjustment device 30 and the free end 27 of the cable 20 exiting the adjustment device 30 extend in different planes. This prevents the free end 27 of the cable 20 from becoming tangled with the incoming cable section. At the same time, the free end 27 of the cable 20 can be grasped more easily due to its protrusion relative to the front side 37. Since the free end 27 of the cable 20 exits on the front side 37, it can be reached with both hands, so that the free end 27 can be grasped with the right or left hand, optionally with a tensile force F Z Pulling is performed in order to shorten the length 23 .

[0033] Figure 7 and Figure 8 Detailed description from Figure 1The retaining buckle 50 is a retaining buckle 50. As already explained, the retaining buckle 50 forms the first connection point 21 in this embodiment, at which the rope 20 is retained on the carrying tool 10. The retaining buckle 50 has a rear side 56 facing the carrying tool 10 and a front side 57 facing away from the carrying tool 10. The retaining buckle 50 includes a fixing area 51, a fastening area 52 and a retaining area 53 in the vertical direction. The fixing area 51 is constructed in a manner similar to the fastening area 48 of the adjustment device 30, so please refer to the corresponding parts of the description. The same reference numerals correspond to the same elements. In the retaining buckle 50, the fixing area 51 and the retaining area 53 extend in a bent manner relative to the plane of the rear side 56, but extend in different directions. As a result, a spacing is intentionally achieved between the carrying tool 10 (for example, the shoulder strap 11) and the retaining area 53, within which the rope 20 can be introduced from the rear side 56 into the retaining area 53 without the need to lift the entire retaining buckle 50 from the carrying tool 10. In addition, the wear of the rope 20 is reduced thereby. The holding area 53 is used to fix the rope 20. In this embodiment, a keyhole-shaped opening 54 is provided, and the rope 20 can be inserted through the opening 54 with the thickened portion 26 at the larger opening side of the opening. For fixing, the rope 20 is then pushed into the area of ​​the narrower side of the opening 54. Since the thickened portion 26 cannot pass through the narrower side of the opening 54, the rope 20 is held at the holding buckle 50 in a form-fitting manner. In order to quickly separate the rope 20 from the carrier 10 at the first connection point 21, a fastening area 52 is arranged between the fixing area 51 and the holding area 53. In the fastening area 52, the holding buckle 50 can be reversibly and tool-free, for example, by means of a snap-on closure mechanism, or connected. The first part of the snap-on closure mechanism remains on the carrier 10, during which the second part of the snap-on closure mechanism is removed together with the first end of the rope 20. In order to remove the first end of the cable 20 from the carrier 10, the first end of the cable 20 can alternatively be moved into the locking hole and the thickened portion 26 can be passed out of the wider side of the opening 54. However, this requires skill and is difficult to achieve with one hand. In addition, the cover of the rubber-elastic cable 20 wears every time it is moved out and into the narrow side of the opening 54. The snap-on closure thus increases the durability of the first connection point 21. The rubber-elastic cable 20 is clamped flatly between the base body 33 and the clamping surface 42 of the clamping element at the second connection point 22, so that the cover is not as severely loaded as on the locking hole side.

[0034] Fig. 9An embodiment of a spring hook 60 for fastening a working tool 70 to a rope 20 is shown. The spring hook 60 has a guide opening 61, a receiving opening 62 and an introduction aid 64. The guide opening 61 is defined all around. In the arranged state, the spring hook 60 slides along the rope 20 with the edge of the guide opening 61. The receiving opening 62 adjoins the guide opening 61 and can be opened at the peripheral section by pivoting a movable arm 63 so that the working tool 70 is suspended at the receiving opening 62. The fixed part of the receiving opening 62 is implemented in a manner extending beyond the receiving opening 62 and forms the introduction aid 64. The working tool 70 is suspended on the introduction aid 64, then the working tool 70 slides along the introduction aid 64, pivots the arm 63 open, and finally hangs in the receiving opening 62. At the end of the insertion aid 64 that protrudes from the receiving opening 62, the distance b between the movable support arm 63 and the insertion aid 64 is at least 80%, in particular at least 100%, of the diameter d of the cable 20. Since the insertion aid 64 makes it easier to find access to the receiving opening 62, the suspension of the work tool 70 on the spring hook 60 is facilitated.
