Description

[0001] The invention relates to an assembly with a component body and a fastening body, which can be connected to each other by means of a bayonet joint.

[0002] Components of the type mentioned at the outset are generally known in the prior art. These components can, for example, be electrically operated components, such as lamps. Various fixing methods are known that make the component body difficult or impossible to loosen or remove from the fastening body when in the closed or connected operating state, particularly when operated with one hand. For example, a rope can be provided to hold the component body in place on the fastening body even when the bayonet joint is released. Bayonet joints with simple fall protection are also known, but simple fall protection is relatively easy to overcome. Simple spring locks can also be installed to prevent the component body from loosening relative to the fastening body, for example by pre-tensioning the bayonet protrusion in the bayonet slot toward the locked position. These known fixing mechanisms are either visible and therefore unsightly, or relatively complex and expensive to implement, or easily overcome, thus having only limited use as a fixing mechanism.

[0003] It is therefore an object of the present invention to provide an assembly of the type mentioned at the outset which has a simple and effective, preferably aesthetically pleasing, fastening mechanism.

[0004] This object is achieved by the subject matter of the independent claims. The dependent claims develop the central idea of the invention in a particularly advantageous manner.

[0005] According to a first aspect, the present invention relates to an assembly having a component body and a fastening body for fastening the component body. The component body can be connected to the fastening body by the bayonet joint of the assembly. The bayonet joint has a bayonet projection (e.g., on the component body side) and a bayonet groove (e.g., on the fastening body side), and the bayonet projection can be in the bayonet groove and guided along the bayonet groove. The bayonet groove has an introduction portion at this, and the bayonet projection can be introduced into the bayonet groove by this introduction portion along the introduction direction. In addition, the bayonet groove also has a functional portion, which extends laterally away from the introduction portion relative to the introduction direction and leads to a locking portion for locking the bayonet projection at its far end, so that the bayonet projection can be locked in a locked position in this locking portion. In addition, the bayonet groove also has a barrier portion, which connects the functional portion and the introduction portion together. The barrier portion is preferably located downstream of the introduction portion in the introduction direction and / or laterally branches from the introduction portion to the functional portion relative to the introduction direction. The bayonet slot also has a pocket extending away from the functional part in the direction opposite to the introduction direction between the blocking portion and the locking portion, in which the bayonet projection can be at least partially contained in the holding position. The assembly also has a blocking element, which can alternatively be positioned in the blocking position in the blocking portion so as to block the passage for the bayonet projection between the introduction portion and the functional part in the bayonet slot. The assembly (such as component body) is configured so that the blocking portion is at least partially exposed in the holding position so that the blocking element is positioned in the blocking portion.

[0006] Through the above-mentioned component design, a pocket is provided in the bayonet slot. By means of this pocket, the component body and the fastening body can be offset relative to each other in the introduction direction by introducing the bayonet projection into the holding position of the pocket, thereby exposing the blocking portion accordingly so that the blocking element can be positioned therein. By accommodating the bayonet projection in the pocket, the component body and the fastening body can be fixed in a safe, preferably suspended position (holding position), thereby simplifying the operation of the assembler. In this position, a fixing device can be provided in the bayonet slot to expose the blocking portion, which can prevent the bayonet projection from loosening from the bayonet slot, thereby preventing the bayonet joint from separating. The bayonet joint can then be closed or fixed by moving the bayonet projection into a locked position and locking it in this position. The bayonet projection then needs to be moved from the locked position back into the holding position, thereby exposing the blocking portion accordingly for loosening. The blocking effect can be eliminated by removing the blocking element from the blocking portion or the blocking position; due to the holding position, this is preferably done in a manner that is convenient for the assembler. The bayonet protrusion can then be introduced into the introduction portion through the re-exposed barrier portion and then guided out of the bayonet slot to disassemble the assembly. This allows for simple yet effective securing of the respective assembly. The bag-shaped portion preferably serves as a folding bag, simultaneously securing the component body and the fastening body relative to each other and making the barrier portion easily accessible so that the blocking element can be positioned in or removed from the blocking position. This simple design provides a relatively inexpensive yet secure bayonet joint. Furthermore, assembly and disassembly can be performed easily, safely, and conveniently.

[0007] The component body preferably has a bayonet projection, and the fastening body preferably has a bayonet slot. This allows for a preferred component design in which the component body, which generally determines the aesthetic appearance, has a less conspicuous portion of the bayonet connection, namely the bayonet projection. This also allows the bayonet connection to be more effectively concealed. The fastening body can also have a bayonet projection, and the component body can also have a bayonet slot.

[0008] The blocking element can be arranged (for example, at the fastening body) so as to be movable in a holding position between a blocking position and a release position, in which the blocking element releases access for the bayonet projection in the bayonet slot between the introduction portion and the functional portion. The blocking element can remain in the assembly due to the provided mobility of the blocking element in the assembly. On the one hand, this simplifies the assembly of the assembly when using a bayonet connection. On the other hand, the blocking element can preferably be provided in a more secure manner. However, it is also conceivable that the blocking element can be removed or taken off to expose the access and then fixed accordingly to be positioned in the blocking portion.

[0009] The blocking element preferably comprises or is a screw. This allows a simple component to be used as the blocking element, which is both simple and intuitive to operate. Furthermore, screws are readily available, making it possible to preferably use standard components. Furthermore, the receiving portion for the blocking element can also be provided, for example, in the form of a simple internal thread (such as a threaded hole). According to a particularly preferred embodiment, the blocking element is or comprises a threaded pin. This allows a particularly simple and easily available component to be used as the blocking element.

[0010] The screw is preferably designed and arranged to be moved between a blocking position and a release position by turning the screw. This makes it particularly easy to provide and operate the corresponding blocking element. Furthermore, a bayonet-type connection can be used to provide a fastening that also meets high safety requirements (e.g., those specified in DIN EN IEC 60598). For example, it is often prohibited to loosen or remove, in particular, covers or housings, with one hand to prevent electric shock.

[0011] The blocking element can preferably have a follower thread profile (eg slot, cross slot, hexagonal socket, hexagonal socket, etc.) so that it can be screwed into a corresponding thread in a simple manner using common tools or moved between a blocking position and a release position.

[0012] The blocking element preferably comprises a pressure piece with a movable pressure-bearing component, wherein the pressure-bearing component is preloaded into or toward a blocking position by a compression spring to block the passage for the bayonet protrusion in the bayonet slot between the introduction portion and the functional portion. This provides a common and easily available component as the blocking element. The pressure piece preferably comprises a sleeve, a compression spring, and a pressure-bearing component. The pressure-bearing component is housed in the sleeve and moves longitudinally between a sleeve bottom (whereby the pressure-bearing component is preferably (substantially) completely contained within the sleeve) and an opposite opening (whereby the pressure-bearing component partially protrudes out of the sleeve through the opening). The compression spring is arranged between the pressure-bearing component and the bottom to preload the pressure-bearing component toward the opening. The sleeve has a stop for the pressure piece in the opening region to securely hold the pressure piece within the sleeve. The sleeve can be provided as a separate component or integrally formed with a component (such as a component body or a fastening body). The compression spring is preferably made of stainless steel. The pressure-bearing component preferably comprises a sphere, for example, made of stainless steel or polyoxymethylene (POM). For example, the pressure piece (e.g., its sleeve) can have an external thread (and thus a screw) in order to be accommodated accordingly in the assembly and to position the pressure part in the blocking position. It is also conceivable that the pressure piece is accommodated in the assembly with a force fit (e.g., by self-clamping) in order to (initially) position the pressure part in the blocking position; for this purpose, the sleeve is preferably made of plastic (preferably thermoplastic) so that it can be easily inserted or pressed into a corresponding recess in the assembly.

[0013] The pressure element is preferably constructed and arranged so that the pressure-bearing component can be selectively moved from the blocking position to the released position, i.e., for example, away from the opening and into the sleeve bottom, against the preload force of the compression spring. This facilitates the connection of the component body and the fastening body, while the bayonet joint is well secured by the preloaded pressure element. Because the pressure element is preloaded toward the blocking position, it automatically pushes back into this position, securely retaining the bayonet projection in the aforementioned passage of the bayonet slot.

[0014] The component body preferably at least partially or completely accommodates the fastening body in the locked position. Thus, the generally functional fastening component (e.g., the fastening body) can be effectively hidden by the generally functional aesthetic component (e.g., the component body). This also allows for a compact structural type.

[0015] The assembly is preferably configured so that the bayonet slot is completely covered, preferably by the component body, in the locked position. This allows the bayonet connector to be concealed in a simple and effective manner in the locked position, while at the same time ensuring effective accessibility of the bayonet connector's fixing means by the blocking element.

[0016] The blocking portion preferably branches off from a distal end of the introduction portion relative to the introduction direction; the distal end is preferably located downstream of or transverse to the introduction direction. The blocking portion preferably also branches off from an end of the introduction portion opposite the introduction opening (for allowing the bayonet protrusion to enter the bayonet slot). This provides an overall simple bayonet slot structure that is easy to manufacture and intuitive to operate.

[0017] The functional part preferably tapers towards the locking part.In this way a simple and effective connection is provided by the bayonet joint.

[0018] The functional part preferably has a starting slope which points in the insertion direction and is inclined in the insertion direction towards the locking part. This starting slope enables an intuitive and simple connection of the bayonet joint when the bayonet projection is moved into the locking position, i.e. when the bayonet projection is inserted into the locking part of the bayonet groove.

[0019] The component body and the fastening body preferably each have contact surfaces that face one another relative to the insertion direction. The bayonet connection is designed so that the contact surfaces press against one another in the locked position. This is preferably achieved by supporting the bayonet projection relative to the locking portion or the activation ramp. This provides a large connecting surface between the component body and the fastening body, thereby ensuring an effective connection of the components in the locked position. The activation ramp can preferably be used to simply press the contact surfaces against one another in the locked position; the activation ramp can thus serve as a support for the bayonet projection.

[0020] The activation ramp can thus serve as a support, press the contact surfaces against one another, and / or provide the aforementioned tapering of the locking portion in a simple manner.

[0021] In a preferred embodiment, a preferably circumferentially closed seal can be provided between the two contact surfaces in order to seal the assembly in this connection region in accordance with the required IP protection class.

[0022] In its protruding direction, the bayonet projection can preferably have a circular or polygonal cross section. For example, the bayonet projection can preferably be configured as a pin or a block. Overall, the bayonet projection can thus be provided in a simple and effective manner.

[0023] The assembly can preferably have a plurality of bayonet joints, which are preferably arranged symmetrically or evenly distributed. Thus, the effect of the connection by the bayonet joint can be correspondingly enhanced, and the connection can be provided particularly safely as a whole. Thus, the load of the connection can also be evenly distributed on the corresponding bayonet joints. The assembly can then have corresponding blocking elements for at least one, a plurality of, or all bayonet joints. The corresponding blocking elements can then be positioned in a blocking position in at least one, a plurality of, or all blocking portions.

[0024] The component preferably has a polygonal, particularly preferably a quadrangular, basic shape or contour, viewed in the direction of insertion. Alternatively, it is conceivable that the component has a circular, preferably annular, basic shape or contour, viewed in the direction of insertion. The component can have essentially any basic shape or contour, viewed in the direction of insertion. The two aforementioned basic shapes (polygonal and circular) are generally the most common and aesthetically pleasing basic shapes or contours of the respective component.

[0025] The component can preferably have at least one bayonet lock on each of two opposing sides. This allows for a uniform distribution of the connection effect, particularly for polygonal components, but also for components of other shapes, such as circular components. Therefore, for polygonal components, the opposing bayonet locks can preferably be brought into the locked position by a translational relative movement between the component body and the fastening body. For circular components, the opposing bayonet locks can preferably be brought into the locked position by a rotational relative movement between the component body and the fastening body.

[0026] The assembly can preferably have a plurality of bayonet joints along a circle and particularly preferably be arranged evenly distributed on this circle. Such a distribution is particularly advantageous for circular or annular assemblies, in which the bayonet joint is closed by a relative rotational movement of the component body and the fastening body about a generally central rotational axis.

[0027] The fastening body preferably includes mounting structures to secure the component body, connected thereto via a bayonet joint, to the mounting surface. This provides a simple yet effective method for securing the fastening body to the mounting surface. In the simplest design, the mounting structures may be through-holes through which fasteners such as screws may be passed to secure the fastening body. Other fastening structures, such as threads and latching structures, are also contemplated.

[0028] According to a particularly preferred design, the component can be a lamp, wherein in this case, the component body preferably has or is a lamp housing. For example, the lamp can be a built-in lamp, a surface-mounted lamp or a pendant lamp.

[0029] The lamp housing can preferably have an illuminating device, in particular an illuminating device for emitting light from the lamp or being illuminated by the lamp. The illuminating device can then preferably have an LED or an LED module. This makes it possible to provide the lamp as a corresponding component in a simple manner.

[0030] The lamp housing preferably accommodates at least a part of the lamp electrical system and / or the lamp electronics for operating the lamp, ie at least a part of the lamp operating element.

[0031] It is also conceivable that the component can be any other possible, preferably electrically operated component, such as a sensor, camera, loudspeaker, etc. The component body can then preferably have or be a corresponding component housing. Such a component housing can then preferably accommodate at least a portion of the component operating elements (e.g., at least a portion of the component electrical system and / or the component electronics) in order to operate the component.

[0032] Furthermore, the fastening body can also support or accommodate at least a portion of component operating elements (eg component electrical system and / or component electronics) or luminaire operating elements (eg luminaire electrical system and / or luminaire electronics) for operating the luminaire.

[0046] Figure 13 Shown Figure 12 A perspective view of the assembly is shown, with the component body being partially transparent for illustration during the second assembly step.

[0047] These figures show two embodiments of an assembly 1 according to the invention. The assembly 1 has a component body 2 and a fastening body 3 for fastening the component body 2.

[0048] The component can be any type of component. The component is preferably an electrically operated component. For example, according to a preferred design, the component 1 can be a lamp, as shown in the embodiment shown in the figure. Then the component body 2 can preferably have or be a lamp housing, especially as Figure 1 and Figure 2 As shown. The lamp housing 2 may preferably have a lighting device. The lighting device may preferably have an LED or an LED module. In addition, as Figure 3 As shown by way of example, the lamp housing 2 may accommodate a portion of lamp operating elements, such as a lamp electrical system and / or lamp electronics for operating the lamp 1 , such as corresponding cables or a lamp driver.

[0049] As especially Figures 2 to 12 As mentioned above, the component body 2 can be connected to the fastening body 3 via the bayonet joint 4 of the assembly 1 .

[0050] The fastening body 3 may preferably have a mounting structure 30 in order to fasten the component body 2 connected to the fastening body 3 via the bayonet joint 4 on, for example, Figure 1 and Figure 11 The mounting surface M is schematically shown in FIG.

[0051] The component 1 can have at least one bayonet connection 4 on each of two opposite sides. This is particularly advantageous for a polygonal (ie, for example, square or rectangular) component 1.

[0052] The component 1 can have multiple bayonet joints 4 along a circle, and preferably they are evenly distributed on the circle, as is the case in the illustrated embodiment. In the illustrated embodiment, three bayonet joints 4 are provided, evenly distributed on the circle or circumference. As shown in the embodiment, this is particularly advantageous for circular components 1.

[0053] Overall, the component 1 can thus have one or more bayonet fittings 4 , wherein a plurality of bayonet fittings 4 are preferably arranged symmetrically or evenly distributed.

[0054] The bayonet connector 4 has a bayonet projection 5, here for example on the component body side. Figure 3 、 Figure 11 and Figure 13 As can be seen by way of example, the bayonet projection 5 has a polygonal or square cross-section when viewed in its protruding direction. Other cross-sectional shapes of the bayonet projection 5 are also conceivable, for example, a circular cross-section when viewed in its protruding direction. The bayonet projection 5 can preferably be configured as a pin or block.

[0055] If from 11A to Figure 11 As can be seen by way of example in step D, the bayonet connection 4 also preferably has a bayonet groove 6 (here for example on the fastening body side), in which and along which the bayonet projection 5 can be guided.

[0056] According to a preferred design, as also shown in the embodiment, the component body 2 may have a bayonet protrusion 5 , and the fastening body 3 may have a bayonet groove 6 .

[0057] like Figure 5 and Figure 13 As shown by way of example in FIG, the bayonet recess 6 has an insertion portion 60, via which the bayonet projection can be introduced in the insertion direction E into the bayonet recess 6.

[0058] In addition, the bayonet slot 6 also has a functional portion 61, which extends laterally away from the introduction portion 60 relative to the introduction direction E and opens at its distal end into a locking portion 62 for locking the bayonet protrusion 5, in which the bayonet protrusion 5 can be locked in the locking position (see Figure 1 and Figure 11 D) in.

[0059] As especially Figures 2 to 5 and Figures 11 to 13 As shown, the functional portion 61 tapers toward the locking portion 62 .

[0060] The functional portion 61 preferably has an activation slope 65 that points in the introduction direction E and is inclined toward the locking portion 62 in the introduction direction E. When the bayonet projection 5 is introduced into the functional portion 61 toward the locking portion 62, it preferably contacts the bayonet projection 5 so as to correspondingly lock the bayonet projection in the locking position.

[0061] The component body 2 and the fastening body 3 preferably each have contact surfaces 21, 31 facing each other with respect to the introduction direction E. The bayonet joint 4 is designed here so that the contact surfaces 21, 31 are in the locking position (see Figure 11 D) Pressing against each other; this is preferably achieved by supporting the bayonet projection 5 relative to the locking portion 62 or the activation ramp 65.

[0062] In a preferred but not illustrated embodiment, the assembly 1 can have a seal which is preferably arranged or pressed in a circumferentially closed manner between the two contact surfaces 21 , 31 in order to produce a seal of the assembly 1 between the two contact surfaces in the locked position.

[0063] As especially Figure 1 and Figure 11 As shown in FIG. 2 , the assembly 1 can preferably be configured such that the bayonet slot 6 is completely covered in the locked position, preferably by the component body 2 .

[0064] Also like Figure 1 and Figure 11 As shown in FIG. 4 , the component body 2 can at least partially (as shown here) or completely accommodate the fastening body 3 in the locked position.

[0065] In addition, the bayonet slot 6 also has a blocking portion 63, which connects the functional portion 61 and the introduction portion 60. The blocking portion 63 can be arranged downstream of the introduction portion 60 in the introduction direction E, or, as shown in the embodiment shown, can be branched laterally from the introduction portion 60 so as to be moved into the functional portion 61 (see, for example Figure 2 、 Figure 3 and Figure 12 In the embodiment shown here, the blocking portion 63 preferably branches off from the distal end of the introduction portion 60 relative to the introduction direction E. The blocking portion 63 may preferably branch off from the end of the introduction portion 60 opposite to the introduction opening 66 for allowing the bayonet protrusion 5 to enter (introduce) the bayonet groove 6.

[0066] Furthermore, the bayonet slot 6 has a pocket 64 extending between the blocking portion 63 and the locking portion 62 and away from the functional portion 61 in a direction opposite to the introduction direction E, in which the bayonet protrusion 5 can be at least partially or completely accommodated in the retaining position.

[0067] The assembly 1 further comprises a blocking element 7 which can optionally be positioned in a blocking position in the blocking portion 63 for blocking the passage 67 for the bayonet projection 5 in the bayonet slot 6 between the insertion portion 60 and the functional portion 61 .

[0068] like Figure 6 、 Figure 9 、 Figure 11 A to Figure 11 C. Figure 12 and Figure 13 As shown, the assembly 1 is configured here so that the blocking portion 63 is at least partially exposed in the holding position in order to position the blocking element 7 in the blocking portion 63. Therefore, introducing the bayonet protrusion 5 into the pocket 64 causes the component body 2 and the fastening body 3 to be relatively offset in a direction opposite to the introduction direction E, so that the blocking portion 63 is correspondingly exposed in the holding position in order to position the blocking element 7.

[0069] In order to position the blocking element 7 in the blocking position in the blocking portion 63 , a blocking element 7 , for example, but preferably a detachable blocking element, can be provided or mounted.

[0070] A blocking element 7 can also be provided (for example on the fastening body 3) for being able to be selectively engaged in a blocking position (see Figures 6 to 8 、 Figure 11 C. Figure 11 D. Figure 12and Figure 13 ) and release position (see Figures 2 to 5 、 Figure 9 、 Figure 10 、 Figure 11 A and Figure 11 B) at least in the holding position (but preferably also in the disassembled state of the assembly 1; e.g. Figure 2 and Figure 3 ), in which release position the blocking element 7 releases a passage 67 for the bayonet projection 5 in the bayonet groove 6 between the introduction portion 60 and the functional portion 61 .

[0071] The blocking element 7 can, for example, have a screw 70 (see Figure 12 and Figure 13 ) or screws (see Figures 2 to 11 ).exist Figures 2 to 11 In the embodiment shown here, the blocking element 7 or the screw 70 is designed as a threaded pin. Figure 4 、 Figure 6 and Figure 9 As exemplarily shown in the detailed drawing in FIG, the screw 70 may be constructed and arranged to move between the blocking position and the releasing position by turning the screw 70 .

[0072] The blocking element 7 or the screw 70 can preferably have a follower thread profile 73 (e.g. a slot, a cross slot, a hexagon socket (illustrated), a hexagonal socket, etc.) so that the blocking element 7 can be screwed into a corresponding thread (here on the side of the fastening body 3) in a simple manner using a common tool W or moved between a blocking position and a release position (see e.g. Figure 4 、 Figure 6 and Figure 9 (Detailed drawing of the ).

[0073] according to Figure 12 and Figure 13 In the second embodiment shown here, the blocking element 7 can also have a pressure piece 71 with a movable pressure-bearing part 72. Figure 12 and Figure 13 As shown by way of example, the pressure member 72 is preferably preloaded into the blocking position by a compression spring to block the passage 67 for the bayonet projection 5 in the bayonet slot 6 between the introduction portion 60 and the functional portion 61. The pressure member 71 is preferably constructed and arranged so that the pressure member 72 can be selectively moved from the blocking position into the release position against the preload of the compression spring. The pressure member 71 can have an external thread and thus a screw 70 so that Figure 12 and Figure 13 It is provided in the installation position shown - here for example screwed into the fastening body 3 in the region of the stop 63 or the channel 67. It is also conceivable that the pressure piece 71 is accommodated in the component 1 in a force-fitting manner (for example by self-clamping) so that Figure 12and Figure 13 In the illustrated installation position, provision is made—here for example, in the region of the stop 63 or the channel 67 , into the fastening body 3 .

[0074] The component 1 preferably has a polygonal, particularly preferably quadrangular (eg square or rectangular) basic shape or contour, viewed in the direction of introduction E. Alternatively, it is also conceivable that: Figures 1 to 13 As shown in the embodiment of FIG, the component 1 has a circular, preferably annular, basic shape or contour, seen in the direction of introduction E. In principle, the invention is not limited to any particular basic shape or contour of the component 1.

[0075] The following describes the installation or removal method of the assembly 1 according to the present invention.

[0076] First, the component body 2 and the fastening body 3 are provided.

[0077] Then, the fastening body 3 can be optionally fastened to the mounting surface M. For this purpose, for example, a screw M1 can be screwed into the mounting surface M through the mounting structure 30 (see, for example, Figure 4 )middle.

[0078] like Figure 4 As shown in the detailed figure of FIG, the blocking element 7 can be moved into the release position to release the passage 67 for the bayonet projection 5 in the bayonet groove 6 between the introduction part 60 and the functional part 61. For this purpose, a tool W can be used to move the blocking element 7, which is designed here as a threaded pin; here, it is screwed into the fastening body 3.

[0079] Then, the bayonet protrusion 5 is introduced into the bayonet slot 6 in the introduction direction E through the introduction portion 60 of the bayonet slot 6 (see Figure 5 and Figure 13 In order to position the component body 2 relative to the fastening body 3 in a simple manner before merging, the two components can each have a positioning mark 22, 32, which indicates to the assembler the correct relative positioning of these components 2, 3. (See Figure 5 Arrow 1).

[0080] Therefore, if Figure 5 As shown by the arrow 2 in FIG, the bayonet protrusion 5 is introduced into the bayonet groove 6 in the introduction direction E and is introduced from the introduction portion 60 through the now exposed channel in the blocking portion 63 into the functional portion 61. There, the bayonet protrusion 5 is introduced or hooked into the pocket 64 in the direction opposite to the introduction direction E, thereby reaching the holding position. Figure 6 、 Figure 11 A and Figure 11 As shown in FIG. 2B , the resulting relative movement of the component body 2 and the fastening body 3 in a direction opposite to the insertion direction E exposes the respective blocking portion 63 in the holding position.

[0081] The blocking element 7 is then positioned in the blocking position in the blocking portion 63 for blocking the passage 67 for the bayonet projection 5 in the bayonet slot 6 between the introduction portion 60 and the functional portion 61. Figure 6 Detailed drawings and Figure 11 C shows by way of example that in order to position the blocking element 7 in the blocking position, the threaded pin 70 is moved or screwed in from the release position to the blocking position, preferably by means of a tool W. This fixes the bayonet projection 5 in the bayonet groove 6 .

[0082] exist Figure 12 and Figure 13 In the embodiment, when the bayonet protrusion 5 passes through the blocking portion 63, the pressure member 72 preferably moves to the release position via the bayonet protrusion 5, thereby passing through the bayonet protrusion passage 67. After passing through, the pressure member 72 moves back to the blocking position due to its preload. This secures the bayonet protrusion 5 in the bayonet slot 6.
