DETAILED DESCRIPTION
[0044] The drawings 1 to 7 show a fragrancing device 1 for fragrancing, for example a road motor vehicle interior of a road motor vehicle, which is not illustrated in the drawings. For simplicity, functionally identical or functionally similar components are provided with identical reference numerals in the drawings, so that a repeated description of functionally identical or functionally similar components can be forgone, in order to avoid repetitions.
[0045] A side view of a preferred exemplary embodiment of a fragrancing device 1 is illustrated in FIG. 1, wherein a carrier 6 of the fragrancing device 1 is arranged with contact at a housing 2 of the fragrancing device 1. A state, which is referred to as installed state 17, is thus illustrated, in which the fragrancing device 1 can be operated, for example.
[0046] Advantageously, the housing 2 according to FIG. 1 is a cylinder housing comprising a round or ring-shaped base cross section, so that this can also be referred to as a circular cylinder housing or an annular housing. In detail, it can also be seen in FIG. 1 that the housing 2 has an internal installation space 4, which leads to the surrounding area by forming an internal installation space opening 5. In FIG. 1, the installation space 4 and the installation space opening 5 is illustrated by means of a breakout. The housing 2 further has a longitudinal housing axis 3, which advantageously extends along the main expansion direction of the housing 2. The longitudinal housing axis 3 can form, for example, an axis of symmetry. Insofar as the installation space opening 5 is not covered by the carrier 6, the installation space 4 can be engaged with through the internal installation space opening 5. As will be described below, fragrance cartridges 9 fastened to the carrier 6 can further be inserted into the installation space 4 through the internal installation space opening 5, see in particular FIGS. 1 and 2. It is furthermore conceivable that further fragrancing components of the fragrancing device 1 are arranged at the housing 2. These fragrancing components can advantageously be arranged at the housing 2 from the outside, or can be fastened to the housing 2 from the inside in the interior of the installation space 4. The housing 2 can be formed in multiple pieces or in one piece.
[0047] The carrier 6, which is formed separately with respect to the housing 2 and which is thus freely movable relative to the housing 2, for example by hand, and which can optionally be attached to the internal installation opening 5 of the installation space 4 so as to form a cover, has the purpose of covering the installation space opening 5 of the installation space 4 in a completely fluid-tight manner, if possible, and to receive or to carry the fragrance cartridge 9 attached to it such that they protrude into the installation space 4 in the installed state 17, thus when the carrier 6 is arranged at the housing 2. The fragrancing device 1 can then consequently be operated in the installed state 17, which is illustrated in FIG. 1.
[0048] The fragrancing device 1 from FIG. 1 is shown in FIG. 2 in a side view, wherein the carrier 6 is now arranged spaced apart from the housing 2 in the direction of the longitudinal housing axis 3 of the housing 2. One of several possible mounting states 18 of the carrier 6, which each deviate from the installed state 17 of the carrier 6, is thus illustrated. To realize the function intended for the carrier 6, the carrier 6 has a cover part 7, which is suitable for covering the installation space opening 5, and a carrier part 10, which is suitable for receiving at least one fragrance cartridge receptacle 8 for receiving at least one fragrance cartridge 9. The cover part 7 and the carrier part 10 can be arranged adjacent to one another by means of a substance-to-substance bond, so that the carrier 6 is quasi realized as integral component.
[0049] It can also be seen in FIG. 2 that, axially in the direction of the longitudinal housing axis 3 between the carrier 6 and the housing 2, the fragrancing device 1 has a guide stop means 11. Said guide stop means serves to guide the carrier 6 as part of a plug-in movement 12, which is suggested in FIG. 2 by means of a double arrow, as part of which the carrier 6 can be moved relative to the housing 2 along the longitudinal housing axis 3 between the installed state 17 of the carrier 6 and deviating mounting states 18 of the carrier 6. So that the guide function of the guide stop means 11 is ensured, it is provided that the guide stop means 11 has a guide pin 15, which is arranged on the cover side, in particular at the cover part 7, and a guide pin receptacle 16, which is arranged on the housing side, in particular at the housing 2, as suggested by means of a dashed line in FIG. 2. The illustrated guide pin 15 can be engaged with contact in a slidably displaceable manner with the guide pin receptacle 16, in order to move the carrier 6 in a slidably displaceable manner as part of the plug-in movement 12.
[0050] In a perspective view, FIG. 3 shows a view obliquely from above onto the fragrancing device from FIG. 2 according to an arrow III entered there, wherein the carrier 6 is completely removed for better visibility of the housing 2, for example it is in one of the mounting states 18. The view onto the housing 2 shows in particular the guide pin 15, which is illustrated in FIG. 4 in an enlarged perspective detail view. The guide pin 15 can be formed by a cylinder sleeve 19, which can be designed, as an example, as circular ring cylinder sleeve 21, and which can have a circular ring-shaped cross section throughout. Along its main expansion direction, the guide pin 15 defines a longitudinal guide pin axis 20.
[0051] It can in particular be seen in FIG. 4 that the cylinder sleeve 19 is embodied to be slotted. This is so, because it has internal slots 23, which are arranged equidistantly from one another, in a cylinder sleeve circumferential direction 22 in a circular manner around the longitudinal guide pint axis 20 and in the direction of the cylinder sleeve circumferential direction 22. The cylinder sleeve 19 thereby defines at least one cylinder sleeve front face 24, which faces away from the housing, in particular a circular ring cylinder sleeve front face 25, into which the slots 23 lead, in each case by forming an internal insertion slot opening 26 in the direction of the longitudinal guide pin axis 20. At least one slot 23 is flanked in a frame-like manner in the cylinder sleeve circumferential direction 22 on both sides by insertion means 27, which are arranged at the cylinder sleeve 19. The insertion means 27 extend, for example, in the direction of the longitudinal guide pin axis 20 along the respective slot 23 to the cylinder sleeve front face 24, where they can transition into the latter. As illustrated in particular in FIG. 4, the insertion means 27 can thereby in each case be formed by a lead-in bevel 28 or a lead-in ramp or a lead-in curve.
[0052] In a top view onto the housing 2 according to an arrow V entered in FIG. 3, FIG. 5 furthermore shows that the cylinder sleeve 19 has a plurality of protrusions 30, which are arranged at an outer jacket surface 29 of the cylinder sleeve 19, which is oriented radially outwards and which, with respect to the longitudinal guide pin axis 20, is only suggested by a small crosshair line in FIG. 5. With respect to the longitudinal guide pin axis 20, the protrusions 30 protrude radially outwards away from the longitudinal guide pin axis 20. The protrusions 30 can furthermore be spaced apart equidistantly from one another in the above-mentioned cylinder sleeve circumferential direction 22 around the longitudinal guide pin axis 20. In an exemplary manner, the protrusions 30 span an angle of approx. 90° between one another in the cylinder sleeve circumferential direction 22. The outer jacket surface 29 and the protrusions 30 are also illustrated in FIG. 4.
[0053] It can further be seen in FIGS. 4 and 5 that each protrusion 30 has a protrusion bevel 31 or a protrusion ramp or a protrusion curve. The protrusion bevel 31 is designed so as to slope radially outwards with respect to the longitudinal guide pin axis 20.
[0054] In a perspective view, FIG. 6 shows the carrier 6 with view obliquely from below according to an arrow VI entered in FIG. 2, so that in particular the fragrance cartridges 9 can be seen. In a top view, FIG. 7 shows the carrier 6 according to an arrow VII entered in FIG. 6. The housing 2 is thereby in each case removed for the benefit of better visibility of the carrier 6. In particular the guide pin receptacle 16 can be seen in FIG. 6 as well as in FIG. 7. The guide pin receptacle 16 is formed by a cylinder receiving sleeve 33, which has a longitudinal guide pin receptacle axis 32, as an example, this can also be a circular ring cylinder receiving sleeve 34 with circular ring-shaped base cross section. The cylinder receiving sleeve 33 has an inner jacket receiving surface 36, which is oriented inwards with respect to the longitudinal guide pin receptacle axis 32. At least one positioning protrusion 37, which protrudes radially inwards with respect to the longitudinal guide pin receptacle axis 32, can be arranged at the inner jacket receiving surface 36. As can be seen in FIG. 5, the positioning protrusion 37 is fastened to the inner jacket receiving surface 36 such that it is arranged with longitudinal distance in the direction of the longitudinal guide pin receptacle axis 32 to a cylinder receiving sleeve front face 38 of the cylinder receiving sleeve 33, in particular a circular ring cylinder receiving sleeve front face 39.
[0055] It can be seen in FIG. 6 as well as in FIG. 7 that the cylinder receiving sleeve 33 defines an internal insertion space 40, which is enclosed in a rotating manner by the inner jacket receiving surface 36 in the direction of a cylinder receiving sleeve circumferential direction 35 revolving around the longitudinal guide pin receptacle axis 32, and into which the cylinder sleeve 19 can be inserted so as to dip in as part of a partial insertion movement 13 of the plug-in movement 12 along the longitudinal housing axis 3, see also FIG. 2. As part of the partial insertion movement 13, the positioning protrusion 37 can advantageously slide with contact along the insertion means 27 of the cylinder sleeve 19, so as to likewise engage with contact in a sliding manner with a slot 23 of the cylinder sleeve 19 as part of the partial insertion movement 13, wherein the carrier 6 centers and/or positions itself with respect to the housing 2 in one of the circumferential directions 22, 35 according to a specified or specifiable angular position. As part of the partial insertion movement 13, the cylinder receiving sleeve front face 38 can moreover slide with contact along at least one protrusion 30 of the cylinder sleeve 19, in order to center and/or to position the carrier 6 with respect to the housing 2. This has the effect that the carrier 6 can be moved in a reliable manner into a specified or specifiable angular position with respect to the housing 2. This furthermore has the effect that the carrier 6 can be guided towards the housing 2 parallel to the longitudinal housing axis 3 with respect to the housing 2.
[0056] The guide pin 15 and the guide pin receptacle 16 can additionally each be centrally aligned with one another with respect to the longitudinal housing axis 3 at least in the installed state 17 of the carrier 6 at the housing 2, see in particular FIG. 1, so that the longitudinal guide pin axis 20 of the guide pin 15 and the longitudinal guide pin receptacle axis 32 of the guide pin receptacle 16 are in particular coaxial to one another.
[0057] It can be seen in FIGS. 2, 3, and 7 that the guide stop means 11 of the fragrancing device 1 has a locking assembly, which is labeled in its entirety with reference numeral 41, for releasably fixing the carrier 6 to the housing 2 in the installed state 17 of the carrier 6. The locking assembly 41 can have male locking parts 43, which are arranged integrally at the cover part 7, there in particular at an edge cover part 42 of the cover part 7, or integrally at an edge bead of the cover part 7. The locking assembly 41 can further have female locking parts 44, which are arranged integrally at the housing 2 and which cooperate elastically with the male locking parts 43 in a clamping or locking manner, at least in the installed state 17 of the carrier 6. The male locking parts 43 and the female locking parts 44 can in particular elastically engage with one another, in order to block a partial insertion counter movement 14 suggested in FIG. 2 of the carrier 6 relative to the housing 2 in a direction opposite to the partial insertion movement 13 along the longitudinal housing axis 3 away from the housing 2. This offers the advantageous effect that the carrier 6 is secured to the housing 2, for example against unintentionally falling out.
[0058] Finally, it should be pointed out that a sealing means 46 can be arranged at the cover part 7 or at a middle cover part 45 of the cover part 7 and/or at the housing 2, in order to cover the internal installation space opening 5 of the installation space 4 in a complete and fluid-tight manner, see in particular FIGS. 1 and 7.
