[0062] A carrying device as a whole is denoted by reference sign 10 in the drawings. FIG. 1a is a front view of the carrying device 10. The carrying device 10 is used to receive a tool, in the form of a cutter 22 here, as shown in FIG. 1b. The carrying device 10 comprises a receiving device 20, a retaining device 30 and a locking device 40.
[0063] The receiving device 20 is configured in the manner of a housing and comprises a receiving space 12, which is delimited by a wall 13. The cutter can be inserted into and removed from the receiving space 12 via an upper opening 11. A wall region 16 forms a guide surface 14, which guides the cutter 22 into the receiving space. An upper end of the wall 16 projects beyond an upper edge of the opening 11 by a length I.
[0064] Openings 15 in the wall 13 give the carrying device 10 a visually appealing appearance and allow particles of dirt that have got into the receiving space 12 to escape. Fastening means in the form of eyes 17 allow a cable or strap (not shown), which is connected to the cutter 22 at the other end, or other objects to be fastened to the carrying device 10. The wall 13 is configured such that it is not possible for anyone to touch a cutting edge of the cutter 22 and injure themselves when the cutter 22 is in the receiving space 12. The receiving device 20 is e.g. substantially made of plastics material. For example, metal and composite plastics materials can also be used for the receiving device 20.
[0065] To secure the cutter 22 in the receiving space 12 against unintentionally falling out, the carrying device 10 comprises a locking device 50 in the present exemplary embodiment. Said device comprises a button 18, by means of which the locking device 50 can be switched between a locking position and a released position. The cutter 22 is secured in the receiving space 12 in the locking position and the cutter 22 can be removed from the receiving space 12 in the released position. In the present exemplary embodiment, the button 18 is configured as a rocker button which is adjustable between the locking position and the released position. Alternatively, however, other types of actuation are also taken into consideration. The locking device 50 is explained in greater detail below.
[0066] FIG. 2 is a side view of the carrying device 10. It shows a base part 31, which is part of a retaining device 30 and part of a fastening device 60, e.g. to fasten the receiving device 20 to the user's clothing or to a piece of furniture. The receiving device 20 is releasably fastened to the base part 31 and is pivotally mounted on the base part 31 about a pivot axis a3 by means of the retaining device 30, which is not shown in full in FIG. 2. This mounting is configured as a sliding bearing in this example. Alternatively, other bearings could be used. However, in this case, a sliding bearing provides the option of easily releasing the receiving device 20 from the base part 31 and only incurs low costs.
[0067] In this exemplary embodiment, the receiving device 30 is pivotable by 360 relative to the base part 31. Alternatively, however, the pivot radius could be limited.
[0068] FIG. 3 is a plan view of the carrying device in which the receiving space 12 can be seen through the opening 11. Openings 15 can be seen on the base of the receiving device 20, through which particles of dirt can escape from the receiving space 12.
[0069] FIG. 4 is an exploded view of the carrying device 10. FIG. 4 shows the button 18, the receiving device 20, the base part 31 and a closure part 36. The base part 31 comprises second retaining means 25, which interact with first retaining means 24 of the receiving device in order to ensure releasable fastening and rotatable mounting. The first retaining means 24 are formed by an edge surface 43 of a cut-out 26 in the wall 13 of the receiving device 20. The edge surface 43 is part of an inner surface 21 of the receiving device 20. In other words, the edge surface 43 surrounds the cut-out 26 and, together with hook projections 42 of the base part 31, prevents the base part 31 from being released from the receiving device 20.
[0070] In this exemplary embodiment, the second retaining means 25 are in the form of three separate blocks 46, which project from the planar base part 31 in the direction x1 towards the receiving device 20, wherein each block 46 is mounted on an end region of at least one spring bar 19, which is elastically deformable. In this way, each block 46 can be moved radially inwards counter to the resilient spring force of the spring bar 19. Gaps between the blocks 46 allow for the radially inward movement. A bearing surface 56 of all three blocks 46 together results in the shape of a circular cylinder, which is intended to penetrate the cut-out 26 and form a joint bearing surface for the rotatable mounting. The number of blocks has been selected here by way of example. Alternatively, two or four blocks 46 could e.g. also be provided, the bearing surfaces 56 of which form a joint bearing surface for the rotatable mounting of the receiving device 20.
[0071] Each block 46 is provided with a hook projection 42 (see FIG. 5a), which projects radially outwards from a free end region of each block 46. When each block 46 moves resiliently inwards, the blocks 46 can be guided through the cut-out 26 in the direction x1 when mounting the receiving device 20 on the base part 31. When the load is removed, the blocks move radially outwards, wherein each hook projection 42 engages over the edge surface 43 of the cut-out 26 on a side of the wall 13 opposite the base part 31. If that is the case, the base part 31 cannot be moved in the direction x2 and released from the receiving device 20. The rotatability of the receiving device 20 relative to the base part 31 in the directions p1 and p2 is ensured owing to the interaction of the bearing surface 56 with the recess 23.
[0072] While mounting the base part 31 in the direction x1 relative to the receiving device 20, oblique surfaces on the hook projections 42 assist the radial movement inwards when they come into contact with the recess 23 of the cut-out 26. To dismount the base part 31, the blocks 46 can be moved radially inwards by applying pressure to their joint centre (pivot axis a3), and the retaining means 25 can then be released from the receiving device 20 in the direction x2. This ability to release the receiving device 20 from the base part 31 facilitates and simplifies cleaning of the carrying device 10.
[0073] Each of the three blocks 46 comprises bar projections 45 extending in the direction in parallel with the pivot axis a3 on the bearing surface 56. When the first retaining means 24 are in engagement with the second retaining means 25, said projections are in contact with the recess 23 of the cut-out 26 and, together with said cut-out, form a sliding bearing for rotatably mounting the receiving device 20 relative to the base part 31 in the directions p1 and p2 about the pivot axis a3.
[0074] The locking device 40 of the carrying device 10 is configured to secure the set rotational position of the receiving device 20 relative to the base part 31. The locking device 40 comprises first latching means 34 (see FIG. 6 to 11), which are assigned to the receiving device 20, and second latching means 35, which are assigned to the base part 31. In this exemplary embodiment, the second latching means 35 (see also FIG. 5a to 5f) comprise a toothed projection 47, which extends in the direction x1 and is directed towards the first latching means 34.
[0075] The toothed projection 47 is formed on a free end region of a spring bar 29, which is free in the plane of the planar base part 31. In the present example, the second latching means comprise three toothed projections 47, which are arranged to be offset in a manner distributed by 120 about the rotational axis a3. A different number of toothed projections 47 can alternatively be selected. In the present construction, the second latching means 35 are arranged radially outside the rotational axis a3 relative to the second retaining means 25, which is advantageous in terms of a compact design.
[0076] FIG. 6 is a rear view of the receiving device 20. It shows that the first latching means 34 are formed by teeth 57, which surround the cut-out 26 or, in other words, are formed on an edge region 53 of the cut-out 26 facing the base part 31. In the present example, the teeth are formed over an angle of 360 based on the rotational axis a3. This allows for locking in all the rotational positions of the receiving device 20 relative to the base part 31 over an angle of 360. If less adjustability of the receiving device 20 is desired, the first latching means 34 can also just be formed over a smaller angle, e.g. 90 from the vertical in both rotational directions p1 and p2.
[0077] FIGS. 7 and 8 show that the teeth 57 take up little installation space and their extension in the direction x1 and x2 is low.
[0078] FIGS. 10 and 11 show details of the retaining device 30 and the locking device 40. FIG. 10 shows the engagement of the toothed projection 47 into a cut-out in the teeth 57. The teeth 47 and 57 are configured as a latching device here, such that, when a minimum torque on the receiving device 20 is exceeded in one of the rotational directions p1 or p2, the toothed projection 47 automatically moves out of engagement with the teeth 57 in the direction x2 and moves into engagement with the teeth 57 in the set rotational position owing to the restoring force of the spring bar 29. FIG. 11 shows how the hook projection 42 releasably engages over the edge surface 43 in the latched position.
[0079] FIG. 12 to 15 show, by way of example, different pivot positions of the receiving device 20 relative to the base part 31. In FIG. 12, an angle 1 of approximately 30 is formed between a central longitudinal axis m1 of the receiving device 20 and a central longitudinal axis m2 of the base part 31. In FIG. 13, the angle 2 between the central longitudinal axes m1 and m2 is approximately 70 and, in FIG. 14, the angle 3 between the central longitudinal axes m1 and m2 is approximately 90.
[0080] The locking device 50, by means of which the cutter 22 retained in the receiving space 12 can be prevented from being removed, is explained in the following. The locking device 50 comprises the button 18, which is pivotally mounted about a pivot axis a1. The geometric pivot axis a1 is formed by a physical shaft 39 (only shown in FIG. 4), which is mounted in shaft cut-outs 41 in the receiving device 20 and forms a joint G1 together therewith (see FIGS. 16 and 17).
[0081] The button 18 is configured as a two-armed lever and, according to FIG. 16, comprises regions 48 and 49, wherein the region 48 is above the pivot axis a1 and the region 49 is below the pivot axis a1. The actuator 18 can be moved between a locked position and a released position in the manner of a rocker by applying pressure to the relevant region 48 or 49. FIG. 16 shows the released position and FIG. 17 shows the locked position. FIG. 18 is a front view of the carrying device, wherein the locking device 50 is in the locked position.
[0082] FIG. 18 shows that the region 48 has a greater longitudinal extension I2 from the pivot axis a1 in the direction z than the region 49, which has a longitudinal extension I3. Furthermore, the region 48 is provided with a greater surface area than the region 49. The locked position is therefore easier to set than the released position.
[0083] The button 18 is surrounded by a raised edge ridge 32, as a result of which it is haptically distinguished and can be easily pressed without being looked at.
[0084] The sectional view according to FIG. 19 shows that, in the locking position, a locking pin 52 of the actuator 18 extends through a through-opening 51 in the wall 13 of the receiving device 20 and engages in the receiving space 12. The button can be pivoted about the axis a1 in the directions v1 and v2. In the released position, which is shown in the sectional view according to FIG. 9, the button 18 has been pivoted in the direction v1 in relation to the position according to FIG. 19 and the locking pin 52 hardly projects into the receiving space 12 at all. From the position according to FIG. 9, the locked position is reached by pivoting in the direction v2.
[0085] FIG. 19 to 22 show that the locking pin 52 is located in the movement path of a cutter 22 received in the receiving space 12here, a housing wall 55 of the cutter 22when the cutter 22 is moved in the direction z2. It is therefore not possible to remove the cutter 22 or for it to unintentionally fall out.
[0086] FIG. 23 is a side view of the carrying device 10 based on FIG. 2, wherein a closure device 60 is provided for fastening the carrying device 10 to a belt or a bar. It comprises a closure part 36, which forms a pivot joint G2 together with the base part 31. For this purpose, the base part 31 forms primary joint means 27, which interact with secondary joint means 38 of the closure part 36.
[0087] A free end region 54 of the closure part 36 can be pivoted away from the base part 31 by means of the pivot joint G2 relative to the base part 31 about the pivot axis a2 (see FIGS. 23 and 24). According to FIG. 23, the closure part 36 has been pivoted away from the base part 31, such that, for example, a belt can be arranged between the base part 31 and the closure part 36.
[0088] At the end region 54, the closure part 36 comprises two elastically deformable arms 33, which are each formed to have a closure projection 37. The arms 33 can be moved resiliently towards one another according to the arrows q1 such that the closure projections 37 can be moved out of the locking relationship with closure cut-outs 28 of the base part 31 by means of actuating levers 44. By relieving the pressure on the actuating levers 44, the latching projections 37 can move away from one another again according to the arrows q2 into engagement with the closure cut-outs 28 owing to resilient restoring force.
[0089] In this way, the carrying device 10 can e.g. be secured to a belt 54 or a bar by it being arranged between the base part 31 and the closure part 36, the closure part 36 then being brought into a parallel position relative to the base part 31, and the closure projections 37 then being brought into engagement with the closure cut-outs 28.
[0090] Alternatively, the joint G2 could also be configured as a film hinge, such that the base part 31 and the closure part 36 are interconnected in one piece. Alternatively, the closure part 36 and the base part 31 could also be formed in one piece and connected by a resilient region which replaces the joint G2. In this case, the base part 31 and the closure part 36 would be connected in the manner of a clasp and the fastening device would not comprise a closure device comprising e.g. a closure projection and a closure cut-out.
[0091] According to another alternative, the retaining device 30 e.g. comprises a one-piece U-shaped part 69 (see FIGS. 32 and 33) comprising two legs 71 and 72 and a connecting bar 73, which replaces the base part 31 and the closure part 36. Furthermore, in this case, the retaining device 30 comprises a shutting part 70, which forms a joint e.g. with the leg 71 and comprises first locking means 74, which can be releasably brought into engagement with second locking means 75 of the leg 72. The carrying part 58 can be arranged between the legs 71 and 72 when the locking means 74 and 75 are not in engagement (see FIG. 32). The first locking means 74 and the second locking means 75 can then be brought into engagement (see FIG. 33). The carrying device 10 then cannot be unintentionally released from the carrying part 58. The spring bars 29, the hook projections 42, the blocks 46 and the toothed projections 47 are likewise formed on the U-shaped part 69 according to the base part 31.
[0092] FIG. 25a to 25f show a carrying part 58 as an individual part, to which the fastening device 60 of the carrying device 10 can be fastened. The carrying part 58 in turn comprises fastening regions 59a and 59b for mounting on a wall e.g. of a piece of furniture or a property. A mounting region 61 of the carrying part 58 to which the fastening device 60 can be fastened is located between the fastening regions 59a and 59b.
[0093] The fastening regions 59a and 59b are provided with fastening means, which are in the form of holes 62 and tabs or eyes 64 in this example. The holes 62 are e.g. provided for a screwed fastening using screws 63, or e.g. a riveted fastening, and the tabs 64 are provided for fastening the carrying part 58 by means of cable ties, wires, etc.
[0094] FIG. 25c shows that a fastening plane 65 formed by the fastening regions 59a and 59b is at a distance from a mounting plane 66 formed by the mounting region 61 by a length I4 in order for it to be possible to easily introduce the closure part 36 or optionally a second leg (not shown) of a fastening part between e.g. a wall and the mounting region 61 of the carrying part 58, such that the mounting region 61 is in contact with a first contact surface 67 on the base part 31 and with a second contact surface 68 on the closure part 36.
[0095] FIG. 26 to 31 show the carrying device 10 as being mounted on the carrying part 58 by means of the fastening device 60. A wall of a piece of furniture or a building to which the carrying part 58 is fastened by means of the fastening regions 59a and 59b is not shown.
