[0001] Riveting tool, collecting container for residual rivet mandrels and method for assembling and disassembling such a collecting container
[0002] The present disclosure relates to a riveting tool, such as a blind rivet setting tool. The present disclosure further relates to a collecting container for residual rivet mandrels and a method for assembling and disassembling such a collecting container.
[0003] Riveting tools are typically used to create a riveted joint between two or more materials, such as sheet metal, at a junction where the materials lie against one another. To create the riveted joint, a plastically deformable, usually cylindrical connecting element, generally referred to as a rivet, is used. The rivet usually has a prefabricated setting head at one end. To create the riveted joint, the rivet is inserted into a connecting hole provided at the joint up to the setting head and then the other end of the rivet is plastically deformed into a closing head.
[0004] Conventional riveting tools usually comprise a riveting tool which is designed to effect a plastic deformation which forms the closing head. To actuate the riveting tool, the riveting tools have a drive device accommodated in a device housing. The drive device is often electromechanical and comprises, for example, an electric motor and a spindle gear designed as a ball screw drive with a threaded spindle and a spindle nut. The spindle nut is usually driven by the electric motor and the threaded spindle is secured against twisting by torque arms so that when the spindle nut rotates, the threaded spindle moves axially and in doing so acts on the riveting tool.
[0005] Such a riveting tool is described in EP 0 527 414 A1. The riveting tool is designed and configured for blind riveting by exerting a pulling movement, pulling a rivet mandrel out of the rivet body of a blind rivet, compressing the rivet body to create a closing head, until the rivet mandrel tears off. The torn-off piece of rivet mandrel can be disposed of in the axial direction, i.e. in the direction of the pulling movement of the rivet mandrel, via a through-bore in the threaded spindle and an adjoining tubular element into a collecting container.
[0006] The collecting container on the riveting tool is detachably attached to the tool housing. For this purpose, an intermediate pipe section is provided which is screwed to the tool housing on the one hand using screws and on the other hand serves as a holder into which the collecting container is detachably inserted using a corresponding extension. Frequently, the pipe section and the extension are each provided with a thread, and the collection container is connected to the pipe section using screws. In order for the collecting container to be held securely on the riveting tool when it is filled with leftover rivet mandrels, a considerable screw-in length is usually required. This means that the riveting tool is relatively bulky in the axial direction, particularly when the collecting container is removed.
[0007] In the course of ongoing development, there is therefore a need to improve the compactness of a riveting tool, particularly when the collecting container is removed. This is based on the expectation that improved compactness when the collecting container is removed will make it easier to reach riveting points that are difficult to access and can only be reached with the collecting container removed. This is also based on the expectation that improved compactness will make the riveting tool lighter and / or easier to handle. Furthermore, this is based on the expectation that despite improved compactness, the collecting container will remain securely attached to the riveting tool even when the collecting container is filled with leftover rivet mandrels.
[0008] One embodiment of a basic riveting tool comprises a collecting container for leftover rivet mandrels and a support structure for the collecting container. An improvement in compactness is offered by an embodiment of the riveting tool in which a fastening mechanism is provided which is designed such that the collecting container can be brought into a fastening position on the support structure by a translational movement relative to the support structure along a spatial axis. The fastening mechanism is preferably further designed such that the collecting container can be moved out of the fastening position by a rotational movement relative to the support structure about the spatial axis. The translational movement is preferably an exclusively translational movement.
[0009] The proposed fastening mechanism makes it possible to mount the collection container on the support structure without screwing. This means that, given its size, the riveting tool can be designed with a shorter axial length in relation to the spatial axis when the collection container is removed than is the case when the riveting tool has a screw thread for screwing on the collection container. At the same time, the proposed fastening mechanism makes it possible to disassemble the collection container from the support structure using a different type of movement than during assembly. The aim is to largely or completely decouple the release force required to release the collection container from the fastening position from the effective direction of the holding force, which is generated during assembly by the translational movement along the spatial axis and holds the collection container in the fastening position in the direction of this axis.This allows the retaining connection between the collecting container and the supporting structure, acting in the direction of the spatial axis, to be made more solid, since no loosening occurs in this direction. Consequently, this prevents the collecting container from accidentally coming loose due to its own weight, for example, when filled with residual rivet mandrels.
[0010] In one embodiment, the fastening mechanism comprises a fastening connection associated with the collecting container and a fastening connection associated with the support structure, which are particularly configured to form a snap connection with one another in the fastening position. Furthermore, the fastening connections are particularly configured such that, in the snap connection, the collecting container is locked against detachment from the support structure in the direction along the spatial axis.
[0011] Such a design enables the riveting tool to be designed more compactly in the axial direction than a screw connection when the collecting container has been removed. The snap connection is also a type of connection which, due to its nature, can build up higher holding forces in the assembly direction, i.e. in the direction of the spatial axis, in order to, for example, hold the collecting container securely in the fastening position when it is largely or completely full of residual rivet mandrels. In this respect, the snap connection can be dimensioned accordingly so that, contrary to the snap direction, i.e. contrary to the assembly direction, unintentional automatic release of the collecting container due to its own weight, for example when filled with residual rivet mandrels, is avoided.
[0012] The improved riveting tool should also be designed such that the fastening mechanism is configured such that, in the snap connection, the collecting container is locked relative to the support structure against rotation about the spatial axis up to a predetermined rotational force, i.e., a rotation lock is present. This counteracts unwanted, particularly premature, release of the collecting container due to a rotational force acting about the spatial axis. This ensures that the collecting container can only be moved out of its fastening position on the support structure when the predetermined rotational force is exceeded and the rotation lock is thus overcome.
[0013] One possible embodiment of the fastening connections can be that one of the fastening connections has at least one locking projection and the other fastening connection has at least one recess, which can be used, for example, as a counter-locking structure. The locking projection and the recess are particularly designed such that, in the fastening position, the locking projection locks into the recess or engages into the recess. The locking projection can be a locking lug, which is, for example, nose-shaped in the direction of the spatial axis.
[0014] In order to achieve locking in the axial direction, according to one embodiment the recess has a locking edge running transversely, in particular orthogonally to the spatial axis. In order to further achieve the rotation lock described above, according to one embodiment the recess is closed at the ends in the circumferential direction with respect to the spatial axis. This can be achieved in that the recess is delimited in the circumferential direction with respect to the spatial axis by spaced-apart side wall surfaces, between which the locking projection is present in the fastening position or when the snap connection is present.In order to overcome the rotation lock when the predetermined rotational force is exceeded and thus to move the collecting container out of the fastening position on the support structure, one embodiment provides that the locking projection and / or the recess has a rounded contour on at least one end section in the circumferential direction with respect to the spatial axis. As a result, the locking effect caused by the engagement of the locking projection in the recess is reduced in the circumferential direction with respect to the spatial axis. The rounded contour is designed for this purpose, for example, such that when the predetermined rotational force is reached, the locking projection and a wall surface of the recess in contact with it slide against one another and as a result the locking projection and the recess are moved away from one another in the radial direction with respect to the spatial axis and brought out of engagement.
[0015] The rounded contour provides a sufficiently high holding force to prevent twisting, as long as the locking projection is fully inserted into the recess. The further the locking projection extends from the recess, the lower the holding force against twisting becomes. A rounded contour is therefore ideal, as it facilitates easy release once the holding force is exceeded.
[0016] Alternatively, the locking projection and / or the recess or locking recess can have an oblique contour on at least one end section in the circumferential direction with respect to the spatial axis. This also makes it possible to reduce the locking effect caused by the engagement of the locking projection in the recess in the circumferential direction with respect to the spatial axis, so that removal of the collecting container from the fastening position on the support structure is facilitated. The oblique contour enables the locking projection to always bear against the wall of the recess at the same angle, so that approximately the same force ratios prevail upon release.
[0017] The improved riveting tool can further be designed such that, in the circumferential direction relative to the spatial axis, the at least one end section of the locking projection and the associated at least one end section of the recess are aligned in the same direction and / or have a corresponding orientation. This measure also supports the release of the snap connection in the manner described above.
[0018] The above-proposed design of the fastening connections, on the one hand, counteracts an unintentional release of the snap connection in the axial direction, and, on the other hand, the rounded or oblique contour allows for an intentional release of the snap connection upon application of a rotational force exceeding a predetermined force value. In other words, this makes it possible for the collection container to be dismantled from the support structure only by a rotational force about the rotation axis, and only when a predetermined rotational force has been built up.
[0019] In one possible embodiment, the locking projection or the recess is arranged on a resilient snap-on tab, and, for example, the resilient snap-on tab is provided at least twice. In this case, the improved riveting tool can be designed such that the at least two resilient snap-on tabs extend with their longitudinal extent in the direction of the spatial axis and, in particular, are radially spaced from one another with respect to the spatial axis and, in particular, are resilient toward one another. This facilitates a technically simple manufacture of the fastening mechanism or the fastening connections.
[0020] The measure that, according to one embodiment, the at least two resilient snap tabs are provided on one of the fastening connections and, in the fastening position, act from the outside against the circumference of the other fastening connection, aims in the same direction.
[0021] The improved riveting device can further be designed such that the support structure has a wall surface which runs around the spatial axis and corresponds to a circumferential surface of the collecting container. In this case, it can be provided that in the fastening position the circumferential wall surface and the circumferential surface overlap one another and form a plug-in connection. This results in the collecting container being supported and / or centered on the support structure in the radial direction when the collecting container is in the fastening position, i.e. when the plug-in connection is established. In one possible embodiment, the support structure is formed on a preferably tubular housing part or comprises such a housing part. For example, the housing part has a round cross-section.For example, the housing part extends with its longitudinal extent in the direction of the axis of rotation and / or is arranged coaxially to the axis of rotation.
[0022] In this embodiment, the improved riveting tool can be designed such that one of the fastening connections is formed on the housing part on mutually opposite surface sections of its outer circumference, and in particular the surface sections run parallel or substantially parallel to one another and in particular the surface sections are flat. This enables a construction of the fastening mechanism in which, in the fastening position, the collecting container is adapted in the radial direction to the outer circumference of the housing part. The fastening connection is then located, for example, countersunk on the straight surface sections relative to the round outer circumference.
[0023] In this embodiment, the improved riveting device can be designed such that the above-described counter-locking structure is arranged, in particular formed, for example, molded, on each of the surface sections. For example, the counter-locking structure is a wall or wall surface, for example, a recess in the respective surface section.
[0024] Preferably, the riveting device has a riveting tool and a drive device located in the housing part for actuating the riveting tool. In this case, the improved riveting device can be designed such that the riveting tool is arranged at one longitudinal end of the housing part and the collecting container is arranged at an opposite longitudinal end of the tubular housing part.
[0025] In a further embodiment, the riveting tool is designed as a hand-held riveting tool and comprises a handle which, for example, has a longitudinal extension transverse to the rotational axis. For example, the handle is formed on a tool housing having the housing, in particular, it is integrally formed thereon. The handle allows the riveting tool to be held in the hand or guided manually. In particular, the handle enables the riveting tool to be manually applied to a location to be riveted.
[0026] According to one aspect, a collecting container for residual rivet mandrels is proposed. In particular, the collecting container is suitable for use as a collecting container for the riveting tool described above. The collecting container comprises, for example, a base body performing a container function and a fastening connection for fastening to a riveting tool, for example the riveting tool described above.
[0027] In one embodiment, the fastening connection is designed to form a fastening mechanism with a fastening connection of the riveting device in such a way that the collecting container can be brought into a fastening position on the riveting device by a translational movement relative to the riveting device along a spatial axis and that the collecting container can be brought out of the fastening position by a rotational movement relative to the riveting device about the spatial axis.
[0028] In particular, the collecting container comprises at least some or all of the features of the collecting container for the riveting tool described above. In this respect, the collecting container also allows the advantages described above in connection with the riveting tool to be achieved.
[0029] According to a further aspect, a method for assembling and disassembling a collecting container for residual rivet mandrels is proposed. For example, the collecting container is the collecting container for residual rivet mandrels described above. The method includes, for example, steps for i) providing a riveting tool, in particular the riveting tool described above; ii) translational movement of the collecting container along a spatial axis into a fastening position on the support structure of the riveting tool; iii) rotating the collecting container relative to the support structure about the spatial axis in order to move the collecting container out of the fastening position on the support structure. This makes it easy for a user to assemble and disassemble the collecting container and require relatively little effort.
[0030] Further details and features are evident from the following description of two embodiments based on the drawings.

[0038] Fig. 10 shows the further exemplary riveting device in the representation of Fig. 9, wherein the collecting container is brought out of the fastening position by a rotational movement relative to the support structure.
[0039] Figure 1 shows an exemplary embodiment of a riveting tool 1, which is also referred to in specialist circles as a setting tool. The exemplary riveting tool is suitable for attaching or setting rivets using the blind riveting method and is therefore designed for use with blind rivets.
[0040] The exemplary riveting device 1 comprises a riveting tool 30 and a drive device (not visible in Figure 1) for actuating the riveting tool 30. The riveting tool 30 is preferably assigned to a tool housing 40. The drive device is preferably assigned to a device housing 50, in particular accommodated therein. The tool housing 40 is preferably a metal housing. The device housing 50 is preferably a plastic housing.
[0041] The exemplary riveting tool 1 can be a hand-held riveting tool. The hand-held riveting tool 1 has, for example, a gripping surface 61, which can be at least partially formed on the tool housing 50. For example, the hand-held riveting tool 1 has a handle part 60, which is at least partially formed by the tool housing 50. The gripping surface 61 or the handle part 60 allows the riveting tool 1 to be held in the hand when it is applied to a workpiece to set a rivet, in particular a blind rivet. The riveting process as such then takes place by actuating the riveting tool 30 via the drive device.
[0042] For example, the drive device is an electromechanical drive device which, for example, comprises an electric motor (not visible in Figure 1). To supply electrical energy to the drive device, a preferably replaceable electrical energy store, such as a rechargeable battery 70, can be provided, which is arranged, for example, in the region of an end of the handle part 60 facing away from the riveting tool 30. In this respect, the riveting device 1 can be a battery-operated device. In principle, the drive device can also be a pneumatic drive device with a pneumatic drive or a hydraulic drive device with a hydraulic drive.
[0043] The riveting tool 30 can comprise a mouthpiece 31 and a mandrel holder which is movable relative to the mouthpiece 31 in the direction of an effective axis W (not visible in Figure 1). For example, the mouthpiece 2.1 is fastened to the tool housing 40, for example screwed thereto. The mandrel holder is preferably accommodated in the tool housing 40 so that it can move in the direction of the effective axis W. For example, the tool housing 40 has an elongated, in particular tubular, base body. In this respect, the tool housing 40 is also referred to in specialist circles as a setting sleeve. For example, the mouthpiece 31 is fastened to one end of the tool housing 40 and the opposite end faces the device housing 50.
[0044] The mouthpiece 31 serves, for example, to receive a rivet (not shown in Figure 1) to be set, in particular a blind rivet, and preferably has a through-hole for inserting the rivet mandrel of the rivet therein. The mandrel receptacle serves, for example, to fix the rivet mandrel so that a displacement-proof connection is created between the received rivet mandrel and the mandrel receptacle. For example, the riveting device 1 has a passage (not visible in Figure 1) which opens from the mandrel receptacle into a collecting container 2. For example, a mandrel disposal path is realized in this way, wherein the collecting container 2 can serve as a collector for leftover rivet mandrels.
[0045] For example, the collecting container 2 is a plastic container and comprises or consists of a plastic material. For example, the collecting container 2 has a base body 2.1 which performs a container function (Figure 5). For example, the collecting container 2 has an opening 2.2 at one end through which residual rivet mandrels can be received by the collecting container 2 (Figure 4). For example, the collecting container 2 is cylindrical. For example, the collecting container 2 has a round cross-section. For example, the collecting container 2 is elongated and extends with its longitudinal extent along the axis of rotation A when it is fastened to the riveting device 1. For example, the collecting container 2 is then arranged coaxially to the axis of rotation A and / or to the effective axis W.
[0046] With regard to the basic structure and the basic mode of operation of the riveting device 1 and in particular of the collecting container 2, for the purpose of completing and supplementing the present disclosure, reference is made to the German patent application with the official file number DE 10 2022 116 431 . 4, with the note that the patent application may assign a meaning to identical terms which differs from the present meaning.
[0047] In the exemplary riveting tool 1, for example, a support structure 3 is provided, to which the collecting container 2 is fastened, i.e. is located in a fastening position B. The support structure 3 can be arranged on a housing part 16, for example of the device housing 50, or in particular can be designed or formed by the housing part 16. For illustration purposes, Figure 2 shows the exemplary riveting tool 1 in an enlarged section in the area of the collecting container 2 and the support structure 3 or the housing part 16 in a perspective view. There, the collecting container 2 is located in the fastening position B on the support structure 3.
[0048] For example, the housing part 16 is tubular. For example, the housing part 16 is elongated. For example, the housing part 16 surrounds the effective axis W and / or is arranged coaxially to the effective axis W. For example, the housing part 16 has a round, in particular circular, cross-section and extends with its longitudinal extent in the direction of the effective axis W. For example, a drive element of the drive device (not visible in Figure 1) is accommodated in the housing part 16 and is designed to be moved along the effective axis W in order to drive the mandrel holder.
[0049] In the exemplary riveting device 1, for example, a fastening mechanism is provided by means of which the collecting container 2 can be brought out of the fastening position B on the support structure 3 or into the fastening position B on the support structure 3. The fastening mechanism is preferably set up in such a way that the collecting container 2 can be brought into the fastening position B on the support structure 3 by a preferably exclusively translational movement relative to the support structure 3 along a spatial axis A. In Figure 1, the translational movement or assembly movement is indicated by the arrow 80 as an example. As can be seen in particular therefrom, the spatial axis A can lie on the effective axis W or coincide with the effective axis W.
[0050] The fastening mechanism is further preferably designed such that the collecting container 2 can be moved out of the fastening position B by a rotational movement relative to the support structure 3 about the spatial axis A. In Figure 1, this rotational movement or dismantling movement is indicated by the arrow 90 as an example. After the dismantling movement has been carried out, the collecting container 2 is moved out of the fastening position B and can be removed from the support structure 3 and emptied and / or deposited at a destination.
[0051] Figures 3 to 8 illustrate by way of example a possible design and / or mode of operation of the fastening mechanism. Figures 3 and 4 show by way of example the collecting container 2 and the support structure 3 in a disassembled state in different perspective views. Figures 5 and 6 each show, in a sectional view along the axis of rotation A, the collecting container 2 in a state during assembly (Figure 5) and in a finally assembled state on the support structure 3 (Figure 6), in which the collecting container 2 is in the fastening position B. Figures 7 and 8 each show, in a sectional view transverse to the axis of rotation A, the collecting container 2 in the fastening position B (Figure 7) and the collecting container 2 in a state in which it has been removed from the fastening position B (Figure 8).
[0052] For example, the fastening mechanism comprises a fastening connection 5, which is assigned to the collecting container 2, in particular arranged thereon, for example, is integrally formed. For example, the fastening mechanism further comprises a fastening connection 6, which is assigned to the support structure 3, in particular arranged thereon, for example, is integrally formed. The fastening connections 5, 6 are preferably designed such that they form a snap connection 20 with one another in the fastening position B (Figure 6).
[0053] In the present disclosure, a "snap connection" is to be understood as meaning, in particular, a preferably releasable form-fitting and / or force-fitting connection between two connection partners, utilizing the material elasticity of at least one of the connection partners, preferably without an additional joining element.
[0054] Preferably, one of the fastening connections 5, 6, in particular the fastening connection 5 assigned to the collecting container 2, has a locking projection 7. For example, the locking projection 7 is a locking lug which is nose-shaped in the direction of the spatial axis A. Preferably, the other fastening connection, in particular the fastening connection 6 assigned to the support structure 3, has a recess 8 which can be used as a counter-locking structure for the locking projection 7.
[0055] The fastening connections 5, 6 are preferably designed such that in the snap connection 20 the collecting container 2 is locked in the direction along the spatial axis A against detachment from the support structure 3. For example, for this purpose the recess 8 has a locking edge 8.1 or snap edge running transversely to the spatial axis A. For example, the locking edge 8.1 forms an edge, in particular the radially outer edge of a wall surface of the recess 8. For example, the locking projection 7 is locked or snapped into place on or around the locking edge 8.1 or against the associated wall surface when the snap connection 20 is produced.
[0056] For example, the locking projection 7 is arranged on a resilient snap tab 12, in particular formed thereon, for example molded thereon. For example, the snap tab 12 is arranged on the collecting container 2, in particular molded thereon. For example, the snap tab 12 projects beyond the edge of the opening 2. 2 of the collecting container 2 in the axial direction with respect to the axis of rotation A.
[0057] In the exemplary riveting tool 1, the resilient snap tab 12 is provided twice. There is therefore the resilient snap tab 12 and a further resilient snap tab 13. Preferably, the further snap tab 13 is also arranged on the collecting container 2, in particular formed thereon. Preferably, the further snap tab 13 has a further locking projection 7', which can be designed, for example, in the same way as the locking projection 7. Preferably, the other fastening connection 6 has a further recess 8', which can be used as a counter-locking structure for the further locking projection 7'. The further recess 8' can be designed in the same way as the recess 8.
[0058] Preferably, the resilient snap tabs 12, 13 extend with their longitudinal extent in the direction of the spatial axis A and are located at a radial distance from one another with respect to the spatial axis A and are designed to be resilient in the direction toward or away from one another. Preferably, in the fastening position B, the resilient snap tabs 12, 13 act from the outside against the circumference of the other fastening connection 6, i.e., the fastening connection 6 assigned to the support structure 3.
[0059] As can be seen in particular from Figures 3 and 4, the recess 8 or 8' can be arranged on or in a surface section 17 or 18 of the housing part 16, which is flat and flattened compared to the outer circumference of the housing part 16. For example, with regard to the cross-section of the housing part 16, the surface sections 17, 18 are formed on opposite sides of the outer circumference and, for example, preferably run parallel to one another. For example, the surface sections 17, 18 each have an area which is designed as a sloped start 19 or 19'. This facilitates the sliding on of the snap tabs 12, 13 with their respective locking lugs 7 or 7' during assembly of the collecting container 2.
[0060] As can be seen in particular from Figures 3 and 4, the support structure 3 or the housing part 16 can have a wall surface 14 which runs around the spatial axis A and corresponds to a peripheral surface 15 of the collecting container 2. The wall surface 14 and the peripheral surface 15 are preferably designed such that they overlap one another in the fastening position B and form a plug-in connection.
[0061] In order to bring the collecting container 2 out of the fastening position B on the support structure 3, i.e. to be able to dismantle it from the support structure 3, the fastening mechanism in the exemplary riveting device 1 is designed in such a way that this is effected by a rotational movement of the collecting container 2 relative to the support structure 3 about the spatial axis A.
[0062] In the exemplary riveting device 1, for example, the fastening mechanism is set up such that by applying a predetermined rotating force about the spatial axis A, the collecting container 2 can be brought out of the fastening position B on the support structure 3 or the snap connection 20 with the support structure 3 and in this way the collecting container 2 can be disassembled from the support structure 3. Preferably, the fastening mechanism is further set up such that up to the predetermined rotating force, the collecting container 2 is locked relative to the support structure 3 against rotating about the spatial axis A, i.e. a rotating lock is present. The collecting container 2 is therefore only moved out of the fastening position B when the predetermined rotating force is exceeded and the rotating lock is thereby overcome.
[0063] In order to achieve the rotation lock, in the exemplary riveting device 1, for example, the recess 8 or 8 ' is closed at the end in the circumferential direction with respect to the spatial axis A. For example, the recess 8 or 8 ' is delimited in the circumferential direction with respect to the spatial axis A by spaced-apart side wall surfaces, between which the locking projection 7 or 7 ' is present in the fastening position B or when the snap connection 20 is present.
[0064] In order to overcome the rotation lock when the predetermined rotational force is exceeded and thus to move the collecting container 2 out of the fastening position B on the support structure 3, the locking projection 7 or 7 ' and / or the recess 8 or 8 ' are provided with a rounded contour 11 on at least one end section 9 or 9 ' in the circumferential direction with respect to the spatial axis A. As a result, the locking effect caused by the engagement of the locking projection 7 or 7 ' in the recess 8 or 8 ' is reduced in the circumferential direction with respect to the spatial axis A.
[0065] As can be seen, for example, from Figures 7 and 8, both the locking projection 7 or 7' and the recess 8 or 8' can be provided with such a rounded contour 11 at one end section 9 or 9' or at both end sections 9, 10 or 9', 10' in the circumferential direction with respect to the spatial axis A. For example, in the locking projection 7 or 7', the rounded contour 11 is curved outwards. For example, in the recess
[0066] 8 or 8', the rounded contour 11 is curved inwards. For example, the rounded contour 11 of the locking projection 7 or 7' and the rounded contour 11 of the recess 8 or 8' correspond to one another.
[0067] Figure 9 shows an example of a further embodiment of a riveting tool 1' in the sectional view corresponding to Figure 7. Components of the further exemplary riveting tool 1' which are structurally identical or functionally identical to components of the exemplary riveting tool 1 of Figures 1 to 8 are provided with the same reference numerals; in this respect, reference is made to the description of the exemplary riveting tool 1 of Figures 1 to 8.
[0068] The further exemplary riveting tool 1' differs from the exemplary riveting tool 1 of Figures 1 to 8 in that, in the circumferential direction with respect to the spatial axis A, the at least one locking lug 7 or 7' and / or the associated counter-locking structure 8 or 8' is provided with an oblique contour 21 on the at least one end section 9 or 9'. Figure 9 illustrates the fastening position B as an example. Figure 10 shows, analogously to Figure 8, the state in which the collecting container 2 is brought out of the fastening position B by a rotational movement relative to the support structure 3.
[0069] As can be seen from this, for example, in the circumferential direction with respect to the spatial axis A, both the locking projection 7 or 7 ' and the recess 8 or 8' at one end section
[0070] 9 or 9' or at both end sections 9, 10 or 9', 10' may be provided with such an oblique contour 21. For example, in the case of the locking projection 7 or 7', the oblique contours 21 of the two end sections 9, 10 run diagonally towards each other towards the outside. For example, in the case of the recess 8 or 8', the oblique contours 21 of the two end sections 9', 10' run diagonally towards each other towards the inside. For example, the oblique contour 21 of the locking projection 7 or 7' and the oblique contour 21 of the recess 8 or 8' correspond to one another.
[0071] The fastening mechanism provided in the exemplary riveting device 1 and the further exemplary riveting device 1' enables the collecting container 2 to be pushed or plugged onto the support structure 3 by a user by means of a translational movement in the direction of the spatial axis A (for example Figure 5) and, in an end position on the support structure 3, the locking projections 7, 7' snap into the corresponding recesses 8, 8' (for example Figure 6). In this end position, the fastening position B described above is reached, in which the fastening connections 5, 6 are in the snap connection 20 with one another and the collecting container 2 is firmly seated on the support structure 3.
[0072] The fastening mechanism provided in the exemplary riveting device 1 and the further exemplary riveting device 1' further makes it possible for the snap-in connection 20 to be released by applying a rotational force about the spatial axis A above a predetermined force value, in that the applied rotational force pushes the snap-in projections 7, 7' and the associated depressions 8, 8' away from one another via the at least one rounded contour 11 or the at least one oblique contour 21 and thereby disengages from one another, i.e. unlocking occurs. The rotational movement means that the snap-in connection 20 can be released with less effort than is the case, for example, when released counter to the snap-in direction, i.e. counter to the assembly movement along the spatial axis A.
