Description

Technical Field

[0001] The present disclosure relates to riveting devices, such as blind rivet installation devices. The present disclosure also relates to a collection container for residual rivet mandrels and a method for installing and removing such a collection container. Background Art

[0002] Riveting devices are usually used to form a riveted connection between two or more materials, such as metal sheets, at a connection point where the materials are against each other. To form the riveted connection, a plastically deformable, usually cylindrical connecting element, usually referred to as a rivet, is used. The rivet usually has a prefabricated mounting head at one end. To form the riveted connection, the rivet is inserted into a connection hole at the connection point up to the mounting head, and the other end of the rivet is then plastically deformed to form a head.

[0003] Conventional riveting devices usually comprise a riveting tool, which is arranged to cause a plastic deformation that forms a ram. In order to actuate the riveting tool, the riveting device has a drive device accommodated in the device housing. The drive device is usually electromechanical and comprises, for example, an electric motor and a spindle drive designed as a lead screw thread drive, which has a threaded spindle and a spindle nut. Usually, the spindle nut is driven by an electric motor and the threaded spindle is secured against twisting by a torque support, so that when the spindle nut rotates, the threaded spindle is displaced in the axial direction and acts on the riveting device in this way.

[0004] Such a riveting device is described in EP 0 527 414 A1. The riveting device is designed for blind rivets and is arranged to subject the rivet body to an upset forming an upset by applying a pulling movement until the rivet mandrel breaks, thereby pulling the rivet mandrel out of the rivet body of the blind rivet. The broken rivet mandrel section can be removed in the axial direction, i.e. in the direction of the pulling movement of the rivet mandrel, through a through-hole in the threaded spindle and a pipe element connected thereto into a collecting container.

[0005] In the riveting device, the collecting container is fastened to the device housing in a detachable manner. For this purpose, an intermediate pipe section is provided, which is screwed to the device housing by means of a screwing element on the one hand and serves as a receiving portion on the other hand, into which the collecting container is detachably inserted by means of a corresponding projection. Usually, the pipe section and the projection are each provided with a threaded portion, and the connection of the collecting container to the pipe section is achieved by screwing. In order to keep the collecting container firmly on the riveting device when the collecting container is filled with residual rivet mandrels, a considerable screw-in length is usually required. This means that the riveting device is relatively space-consuming in the axial direction, especially when the collecting container is removed.

[0006] In the course of continuous improvement, there is therefore a need to increase the compactness of the riveting tool, in particular with the collecting container removed. This is based on the expectation that with the collecting container removed, the improved compactness will make it easier to reach those riveting points that are difficult to access and can only be accessed after the collecting container has been removed. This is also based on the expectation that the improved compactness will make the riveting device lighter and / or easier to handle. This is also based on the expectation that despite the improved compactness, the collecting container remains firmly held on the riveting device even if it is filled with residual rivet mandrels. Summary of the invention

[0007] An embodiment of the basic riveting device comprises a collection container for residual rivet mandrels and a support structure for the collection container. An improvement in compactness is provided by an embodiment of the riveting device in which a fastening mechanism is provided, which is arranged such that the collection container is brought into a fastened position on the support structure by a translational movement relative to the support structure along a spatial axis. Preferably, the fastening mechanism is also designed such that the collection container is brought out of the fastened position by a rotational movement relative to the support structure about the spatial axis. Preferably, the translational movement is a movement that is only translational.

[0008] The proposed fastening mechanism can be used to mount the collection container on the support structure without screwing. Thus, compared with the case where the riveting device has a thread for screwing the collection container, the riveting device of the present application can be realized with a shorter axial structural length relative to the spatial axis in terms of structural dimensions when the collection container is removed. At the same time, the proposed fastening mechanism can be used to remove the collection container from the support structure by different types of movements during installation. The purpose is to decouple the release force required to release the collection container from the fastening position to a large extent or completely decouple the direction of action of the retaining force, which is generated during installation by a translational movement along the spatial axis and holds the collection container in the fastening position in the direction of the axis. The connection between the collection container and the support structure that acts in the direction of the spatial axis can be made stronger because no loosening can occur in this direction. Therefore, this can prevent the collection container from accidentally loosening due to its own weight, for example, when the collection container is filled with residual rivet mandrels, the collection container is prevented from accidentally loosening due to its own weight.

[0009] In one embodiment, the fastening means comprises a fastening connection assigned to the collection container and a fastening connection assigned to the support structure, and in particular, the fastening connections are designed to form a snap connection with each other in the fastened position. In addition, the fastening connections are particularly arranged so that: in the snap connection, the collection container is locked against loosening from the support structure in the direction of the spatial axis.

[0010] Compared to a threaded connection, such a design enables a more compact design of the riveting device in the axial direction, which is desired, when the collecting container is removed. In addition, the snap-in connection is also a type of connection which, due to its system itself, is able to establish a higher holding force in the installation direction (i.e. in the direction of the spatial axis), so as to hold the collecting container securely in the fastened position, for example, when the collecting container is largely or completely filled with residual rivet mandrels. In this regard, the snap-in connection can be dimensioned by a suitable design to avoid an unintentional spontaneous loosening of the collecting container, for example, when filled with residual rivet mandrels, due to its own weight, in the opposite direction of the snap-in direction, i.e. in the opposite direction of the installation direction.

[0011] Furthermore, the improved riveting device should be designed such that the fastening means are arranged such that: in the snap connection, the collecting container is locked relative to the support structure against rotation about the spatial axis until a predetermined rotational force is reached, i.e. a rotational lock is present. This prevents the collecting container from accidentally, in particular prematurely, loosening due to rotational forces acting about the spatial axis. This makes it possible to release the collecting container from the fastened position on the support structure when the predetermined rotational force is exceeded and the rotational lock is thus overcome.

[0012] One possible embodiment of the fastening connection is that one of the fastening connections has at least one latching projection and the other fastening connection has at least one recess, which can be used, for example, as a cooperating latching structure. The latching projection and the recess are particularly designed so that, in the fastening position, the latching projection is latched in the recess or engages in the recess. The latching projection can be a latching nose, for example, which is nose-shaped in the direction of the spatial axis.

[0013] In order to achieve an effective latching effect in the axial direction, according to one embodiment, the recess has a latching edge extending transversely, in particular a latching edge extending orthogonally to the spatial axis. In order to further achieve the rotational locking described above, according to one embodiment, the recess is closed at the ends in the circumferential direction relative to the spatial axis. This can be achieved in that the recess is delimited in the circumferential direction relative to the spatial axis by side wall surfaces spaced apart from each other, and in the fastened position or when the snap connection is present, the latching projection is located between the side wall surfaces spaced apart from each other.

[0014] In order to overcome the rotational lock when a predetermined rotational force is exceeded and thus to release the collection container from the fastening position on the support structure, it is provided according to one embodiment that the latching projection and / or the recess has a rounded contour on at least one end section in the circumferential direction relative to the spatial axis. As a result, the locking effect caused by the engagement of the latching projection in the recess is reduced in the circumferential direction relative to the spatial axis. To this end, the rounded contour is designed, for example, so that when the predetermined rotational force is reached, the latching projection and the wall surface of the recess in contact with the latching projection slide relative to each other, whereby the latching projection and the recess move away from each other and are released from engagement in the radial direction relative to the spatial axis.

[0015] A sufficiently high holding force is provided by the rounded contour to prevent twisting, as long as the latching projection is fully inserted into the recess. The further the latching projection protrudes from the recess, the lower the holding force to prevent twisting. In this respect, a rounded contour is suitable, since it facilitates easy release after the holding force has been exceeded.

[0016] Alternatively, the latching projection and / or the recess or the latching groove on at least one end section can have an inclined profile relative to the spatial axis. This also reduces the locking effect caused by the engagement of the latching projection in the recess in the circumferential direction relative to the spatial axis, thereby facilitating the release of the collection container from the fastening position on the support structure. The inclined profile enables the latching projection to always rest on the wall of the recess at the same angle, so that the force ratios during release are approximately the same.

[0017] The improved riveting device can also be designed such that in the circumferential direction relative to the spatial axis, at least one end section of the latching projection and at least one associated end section of the recess are formed in an aligned manner with respect to one another and / or have a corresponding orientation. This measure also supports the release of the snap connection in the manner described above.

[0018] By means of the design of the fastening connection proposed above, on the one hand an unintentional release of the snap connection in the axial direction is prevented and, on the other hand, the rounded or inclined profile enables an intentional release of the snap connection when a rotational force exceeding a predetermined force value is applied. In other words, this makes it possible to remove the collecting container from the support structure only by a rotational force about the spatial axis and only when the predetermined rotational force has been established.

[0019] In one possible embodiment, the locking protrusion or recess is arranged on the elastic butt strap, and at least two elastic butt straps are provided, for example. In this case, the improved riveting device can be designed so that: at least two elastic butt straps extend in the direction of the spatial axis with a longitudinal extension, and in particular, at least two elastic butt straps are radially spaced from each other with respect to the spatial axis, and in particular, at least two elastic butt straps are elastic in the direction toward each other. This is conducive to the technically simple production of the fastening mechanism or the fastening connection.

[0020] The following measures have the same purpose: According to one embodiment, at least two elastic butt straps are arranged on one of the fastening elements and act from the outside on a circumference of the other fastening element in the fastened position.

[0021] The improved riveting device can also be designed so that the support structure has a wall surface extending circumferentially around the spatial axis, the wall surface corresponding to the circumferential surface of the collecting container. In this case, it is provided that in the fastened position, the peripheral wall surface and the circumferential surface overlap each other and form a plug connection. This achieves that when the collecting container is in the fastened position, i.e. when the plug connection is formed, the collecting container is supported on the support structure and / or centered in the radial direction on the supporting structure.

[0022] 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 circular cross section. For example, the housing part extends with its longitudinal extension in the direction of the spatial axis and / or is arranged coaxially with the spatial axis.

[0023] In this embodiment, the improved riveting device can be designed such that: one of the fastening connections is formed on the housing part on opposite surface sections of the outer circumferential portion of the housing part, and in particular, the surface sections extend parallel to each other or approximately parallel to each other, and in particular the surface sections are flat. This enables a design of the fastening mechanism, in which in the fastened position the collecting container is adapted to the outer circumferential portion of the housing part in the radial direction. The fastening connection is sunken, for example, on a straight surface section relative to the circular outer circumferential portion.

[0024] In this embodiment, the improved riveting device can be designed so that the above-mentioned matching locking structures are respectively arranged on the surface segments, in particular formed on the surface segments, such as molded on the surface segments. For example, the matching locking structures are walls or wall surfaces, such as recesses on the relevant surface segments.

[0025] Preferably, the riveting device has a riveting tool and a drive device in the housing part for actuating the riveting tool. In this case, the improved riveting device can be designed so that: the riveting tool is arranged at one longitudinal end of the housing part, and the collecting container is arranged at the opposite longitudinal end of the tubular housing part.

[0026] In a further embodiment, the riveting device is designed as a manual riveting device and comprises a handle portion, for example, the handle portion has a longitudinal extension transverse to the spatial axis. For example, the handle portion is formed on the device housing with the housing portion, in particular is molded on the device housing. The handle allows the riveting device to be held in the hand or to be manually guided. In particular, the handle portion allows the riveting device to be manually placed at the point to be riveted.

[0027] According to one aspect, a collection container for residual rivet mandrels is provided. In particular, the collection container is suitable as a collection container for the above-mentioned riveting device. The collection container comprises, for example: a base body serving as a container; and a fastening connection for fastening to a riveting device, such as the riveting device described above.

[0028] In one embodiment, the fastening connector is configured to form a fastening mechanism with the fastening connector of the riveting device, so that: by a translational movement along the spatial axis relative to the riveting device, the collecting container can be brought into a fastening position on the riveting device, and by a rotational movement around the spatial axis relative to the riveting device, the collecting container can be disengaged from the fastening position.

[0029] In particular, the collecting container comprises at least some or all of the features of the collecting container for the above-mentioned riveting device. In this respect, the advantages mentioned above in connection with the riveting device can also be achieved by the collecting container.

[0030] According to another aspect, a method for mounting and dismounting a collecting container for holding a rivet mandrel is provided. For example, the collecting container is the above-mentioned collecting container for holding a rivet mandrel. The method comprises, for example, the following steps: i) providing a riveting device, in particular the above-mentioned riveting device; ii) moving the collecting container in translation along a spatial axis to a fastening position on a support structure of the riveting device; iii) rotating the collecting container relative to the support structure about the spatial axis to disengage the collecting container from the fastening position on the support structure. This allows the user to mount and dismount the collecting container easily and with less effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 An embodiment of a riveting device 1 is shown by way of example, which is also referred to as a mounting device in the professional field. The exemplary riveting device is suitable for setting or mounting rivets using a blind riveting method and is therefore designed to use blind rivets.

[0042] The exemplary riveting device 1 comprises a riveting tool 30 and a driving device for actuating the riveting tool 30 (in Figure 1 Preferably, the riveting tool 30 is assigned to the tool holder 40. Preferably, the drive device is assigned to the device housing 50, in particular, the drive device is accommodated in the device housing 50. Preferably, the tool holder 40 is a metal holder. Preferably, the device housing 50 is a plastic housing.

[0043] The exemplary riveting device 1 may be a manual riveting device. For example, the manual riveting device 1 has a gripping surface 61, which may be at least partially formed on the device housing 50. For example, the manual riveting device 1 has a handle portion 60, which is at least partially formed by the device housing 50. The gripping surface 61 or the handle portion 60 can be used to hold the riveting device 1 in the hand when placing the riveting device 1 on a workpiece to be riveted, in particular a workpiece to be blind riveted. The riveting process itself is then performed by actuating the riveting tool 30 via the drive device.

[0044] For example, the drive device is an electromechanical drive device, for example, the drive device comprises an electric motor (in Figure 1 For the electrical energy supply of the drive device, a preferably replaceable electrical energy storage device, such as a battery 70, can be provided, which is located, for example, in the end region of the handle part 60 remote from the riveting tool 30. In this respect, the riveting device 1 can be a battery-operated tool. In principle, the drive device can also be a pneumatic drive with a pneumatic drive or a hydraulic drive with a hydraulic drive.

[0045] The riveting tool 30 may include a rivet nozzle 31 and a mandrel receiving member (in Figure 1 The mandrel holder is a tool holder 40 (not visible in the figure), which can be moved relative to the rivet nozzle 31 in the direction of the action axis W. For example, the rivet nozzle 31 is fastened to the tool holder 40, for example, it is screwed on the tool holder 40. Preferably, the mandrel holder is accommodated in the tool holder 40 in a manner that it can be moved in the direction of the action axis W. For example, the tool holder 40 has an elongated, in particular tubular, base body. In this respect, the tool holder 40 is also referred to as a mounting sleeve in the professional field. For example, the rivet nozzle 31 is fastened to one end of the tool holder 40, while the opposite end faces the device housing 50.

[0046] The rivet mouth 31 is used, for example, to receive a rivet to be installed (not shown). Figure 1), in particular a blind rivet, and the rivet mouth 31 preferably has a through hole so that the rivet mandrel of the rivet can be introduced into the rivet mouth 31. For example, the mandrel receiving part is used to fix the rivet mandrel so that a non-displaceable connection is formed between the rivet mandrel and the mandrel receiving part. For example, the riveting device 1 has a channel (in Figure 1 2 ), which leads from the mandrel holder to the collecting container 2. For example, a mandrel disposal path is realized in this way, wherein the collecting container 2 can be used as a collector for residual rivet mandrels.

[0047] 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 ( Figure 5 For example, the collecting container 2 has an opening 2.2 at one end, through which the residual rivet mandrel can be received by the collecting container 2 ( Figure 4 ). For example, the shape of the collecting container 2 is cylindrical. For example, the collecting container 2 has a circular cross section. For example, the collecting container 2 is elongated and, when the collecting container 2 is fastened to the riveting device 1, the collecting container 2 extends along the spatial axis A via the longitudinal extension. For example, the collecting container 2 is arranged coaxially with the spatial axis A and / or the action axis W.

[0048] With regard to the basic construction and basic working principle of the riveting device 1 and in particular the collecting container 2 , in order to complete and supplement the present disclosure, reference is made to the German patent application with official application number DE 10 2022 116 431.4, wherein it should be noted that the patent application may assign different meanings to the same terms than in the present application.

[0049] For example, in the exemplary riveting device 1 , a support structure 3 is provided to which the collecting container 2 is fastened, i.e. the collecting container 2 is located in the fastening position B. The support structure 3 can be arranged, for example, on a housing part 16 of a device housing 50 or can in particular be formed by the housing part 16. For illustration, Figure 2 An exemplary riveting device 1 is shown in an enlarged detail in the region of the collecting container 2 and the supporting structure 3 or in an enlarged detail of the housing part 16 in a perspective view. In this case, the collecting container 2 is located in a fastening position B on the supporting structure 3 .

[0050] For example, the housing part 16 is tubular. For example, the housing part 16 is elongated. For example, the housing part 16 is arranged around the action axis W and / or coaxially with the action axis W. For example, the housing part 16 has an annular, in particular circular, cross section and extends in its longitudinal extent in the direction of the action axis W. For example, the drive element of the drive device (in Figure 1The spindle receiving member (not visible in FIG. 1 ) is housed in a housing part 16 which is designed to move along an active axis W to drive the spindle receiving member.

[0051] For example, in the exemplary riveting device 1, a fastening mechanism is provided, by which the collecting container 2 can be disengaged from the fastening position B on the support structure 3 or the collecting container 2 can be brought into the fastening position B on the support structure 3. The fastening mechanism is preferably arranged so that the collecting container 2 can be brought into the fastening position B on the support structure 3 by a preferably only translational movement along the spatial axis A relative to the support structure 3. Figure 1 An example of a translational movement is shown. The mounting movement is indicated by arrow 80. It can be seen in particular that the spatial axis A can lie on the action axis W or can coincide with the action axis W.

[0052] The securing means is also preferably designed such that the collecting container 2 can be released from the securing position B by a rotational movement about the spatial axis A relative to the support structure 3 . Figure 1 An example of this rotational movement is shown. The disassembly movement is indicated by arrow 90. After the disassembly movement has been performed, the collecting container 2 is released from the fastening position B and can be removed from the supporting structure 3 and emptied and / or stored at a target location.

[0053] Figures 3 to 8 Possible designs and / or modes of operation of the fastening mechanisms are shown by way of example. Figure 3 and Figure 4 The collecting container 2 and the supporting structure 3 are shown by way of example in a disassembled state in different perspective views. Figure 5 and Figure 6 The collecting container 2 ( Figure 5 ) and the collection container 2 in the final state of being mounted on the support structure 3 ( Figure 6 ), in the final state of being mounted on the support structure 3, the collecting container 2 is in the fastening position B. Figure 7 and Figure 8 The collecting container 2 ( Figure 7 ) and the collection container 2 in a state of being detached from the fastening position B ( Figure 8 ).

[0054] For example, the fastening mechanism comprises a fastening connection 5, which is assigned to the collecting container 2, in particular the fastening connection 5 is arranged on the collecting container 2, for example molded on the collecting container 2. For example, the fastening mechanism also comprises a fastening connection 6, which is assigned to the supporting structure 3, in particular the fastening connection 6 is arranged on the supporting structure 3, for example molded on the supporting structure 3. Preferably, the fastening connections 5, 6 are arranged such that the fastening connections 5, 6 form a snap connection 20 ( Figure 6 ).

[0055] In the present disclosure, a "snap-in connection" is to be understood in particular as a (preferably detachable) form-fitting and / or force-fitting connection between two connecting parts formed by utilizing the material elasticity of at least one of the connecting partners, preferably without additional engaging elements.

[0056] Preferably, one of the fastening elements 5 , 6 has a latching projection 7 , in particular the fastening element 5 assigned to the collecting container 2 has a latching projection 7 . For example, the latching projection 7 is a latching nose that is nose-shaped in the direction of the spatial axis A. Preferably, the other fastening element has a recess 8 , in particular the fastening element 6 assigned to the supporting structure 3 has a recess 8 , which can serve as a mating latching structure for the latching projection 7 .

[0057] Preferably, the fastening connections 5, 6 are arranged such that, in the snap connection 20, the collecting container 2 is locked in the direction along the spatial axis A against loosening from the supporting structure 3. For example, the recess 8 has a latching edge 8.1 extending transversely to the spatial axis A. For example, the latching edge 8.1 forms an edge, in particular a radially outer edge of a wall surface of the recess 8. For example, when the snap connection 20 is formed, the latching projection 7 latches or catches on or around the latching edge 8.1 or against a corresponding wall surface.

[0058] For example, the latching projection 7 is arranged on the elastic butt strap 12, in particular, the latching projection 7 is formed on the elastic butt strap 12, for example, molded on the elastic butt strap 12. For example, the butt strap 12 is arranged on the collecting container 2, in particular molded on the collecting container 2. For example, the butt strap 12 protrudes from the edge of the opening 2.2 of the collecting container 2 in the axial direction about the spatial axis A.

[0059] In the exemplary riveting device 1, two elastic butt straps 12 are provided. Therefore, there is an elastic butt strap 12 and a further elastic butt strap 13. Preferably, the further butt strap 13 is also arranged on the collecting container 2, in particular molded on the collecting container 2. Preferably, the further butt strap 13 has a further latching projection 7', for example, the further latching projection 7' ​​can be designed in the same way as the latching projection 7. Preferably, the further fastening connection 6 has a further recess 8', which can serve as a matching latching structure for the further latching projection 7'. The further recess 8' can be formed in the same way as the recess 8.

[0060] Preferably, the elastic butt straps 12, 13 extend with their longitudinal extension in the direction of the spatial axis A and are radially spaced apart from one another relative to the spatial axis A and are designed to be elastic in directions toward or away from one another. Preferably, the elastic butt straps 12, 13 in the fastening position B act from the outside on the circumference of the other fastening connection 6, i.e., on the circumference of the fastening connection 6 assigned to the support structure 3.

[0061] In particular, from Figure 3 and Figure 4 It can be seen that 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 relative to the circumference of the housing part 16. For example, for the cross section of the housing part 16, the surface sections 17, 18 are formed on opposite sides of the outer circumference and are preferably parallel to each other. For example, the surface sections 17, 18 each have an area designed as a ramp 19 or 19'. This makes it easier to slide the docking straps 12, 13 using their corresponding latching projections 7 and 7' when installing the collection container 2.

[0062] In particular, from Figure 3 and Figure 4 It can be seen that the support structure 3 or the housing part 16 can have a wall surface 14 extending circumferentially around the spatial axis A, which wall surface 14 corresponds to a circumferential surface 15 of the collecting container 2. Preferably, the wall surface 14 and the circumferential surface 15 are designed so that they overlap each other in the fastening position B and form a plug connection.

[0063] In order to release the collecting container 2 from the fastening position B on the supporting structure 3 , i.e. to be able to remove the collecting container 2 from the supporting structure 3 , the fastening mechanism in the exemplary riveting device 1 is designed to achieve this by a rotational movement of the collecting container 2 relative to the supporting structure 3 about the spatial axis A.

[0064] For example, in the exemplary riveting device 1, the fastening mechanism is designed so that: by applying a predetermined rotational force about the spatial axis A, the collection container 2 can be disengaged from the fastening position B on the support structure 3 or from the snap connection 20 of the support structure 3, and in this way the collection container 2 can be removed from the support structure 3. Preferably, the fastening mechanism is also designed so that: before the predetermined rotational force is reached, the collection container 2 is locked relative to the support structure 3, so that it cannot be rotated about the spatial axis A, that is, there is a rotational lock. Therefore, the collection container 2 can only be moved out of the fastening position B when the predetermined rotational force is exceeded and the rotational lock is overcome thereby.

[0065] In order to achieve rotational locking, in the exemplary riveting device 1, for example, the recess 8 or 8' is closed at the ends in the circumferential direction relative to the spatial axis A. For example, the recess 8 or 8' is bounded by spaced side wall surfaces in the circumferential direction relative to the spatial axis A, and in the fastening position B or when the snap connection 20 is present, the latching projection 7 or 7' is located between the spaced side wall surfaces.

[0066] In order to overcome the rotational locking when a predetermined rotational force is exceeded and thus to release the collecting container 2 from the fastening position B on the support structure 3, the latching 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 relative to the spatial axis A. As a result, the locking effect caused by the engagement of the latching projection 7 or 7' in the recess 8 or 8' is reduced in the circumferential direction relative to the spatial axis A.

[0067] For example, from Figure 7 and Figure 8 It can be seen that in the circumferential direction relative to the spatial axis A, the latching projection 7 or 7' and the recess 8 or 8' can be provided with a rounded contour 11 on one end section 9 or 9' or on both end sections 9, 10 or 9', 10'. For example, in the latching projection 7 or 7', the rounded contour 11 is bent outward. For example, in the recess 8 or 8', the rounded contour 11 is bent inward. For example, the rounded contour 11 of the latching projection 7 or 7' and the rounded contour 11 of the recess 8 or 8' correspond to each other.

[0068] Fig. 9 With Figure 7 The corresponding cross-sectional view shows by way of example another embodiment of the riveting device 1 '. The components of the other exemplary riveting device 1 ' are structurally or functionally similar to those of the embodiment of the present invention. Figures 1 to 8 The components of the exemplary riveting device 1 of FIG. 1 are identical and are provided with the same reference numerals; in this regard, reference is made to FIG. Figures 1 to 8 Description of an exemplary riveting device 1 .

[0069] Another exemplary riveting device 1 'is Figures 1 to 8 The exemplary riveting device 1 of exemplarily differs in that, in the circumferential direction relative to the spatial axis A, at least one latching projection 7 ′ or 7 ′ and / or the corresponding mating latching structure 8 or 8 ′ is provided with an inclined contour 21 on at least one end section 9 or 9 ′. Fig. 9 The fastening position B is shown by way of example. Fig.10 Similar to Figure 8 , shows a state in which the collecting container 2 is released from the fastening position B by a rotational movement relative to the supporting structure 3 .

[0070] For example, it can be seen that in the circumferential direction relative to the spatial axis A, the latching projection 7 or 7' and the recess 8 or 8' have such an inclined contour 21 on one end section 9 or 9' or on both end sections 9, 10 or 9', 10'. For example, in the latching projection 7 or 7', the inclined contours 21 of the two end sections 9, 10 extend outwardly in an inclined manner relative to each other. For example, in the recess 8 or 8', the inclined contours 21 of the two end sections 9', 10' extend inwardly in an inclined manner relative to each other. For example, the inclined contours 21 of the latching projection 7 or 7' and the inclined contours 21 of the recess 8 or 8' correspond to each other.

[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 moved by a translation movement in the direction of the spatial axis A (eg Figure 5 ) is pushed or inserted onto the support structure 3 and in the end position on the support structure 3 the latching projections 7, 7' latch into the corresponding recesses 8, 8' (eg Figure 6 In this end position, the previously described fastening position B is reached, in which the fastening connections 5 , 6 are in a snap connection 20 and the collecting container 2 remains securely on the supporting structure 3 .

[0072] The fastening mechanism provided in the exemplary riveting device 1 and the further exemplary riveting device 1' also enables the latching connection 20 to be released by applying a rotational force around the spatial axis A that is higher than a predetermined force value, because the applied rotational force pushes the latching projections 7, 7' and the corresponding recesses 8, 8' away from each other through at least one rounded contour 11 or at least one inclined contour 21, thereby causing the latching projections 7, 7' and the corresponding recesses 8, 8' to disengage from each other, i.e., unlocking occurs. Compared to releasing the latching connection 20 against the latching direction, i.e., releasing the latching connection 20 against the installation movement along the spatial axis A, due to the rotational movement, the latching connection 20 can be released with less force.
