DETAILED DESCRIPTION
In the description hereunder of different exemplary embodiments of the invention, functionally equivalent elements are provided with the same reference signs even in the event of a variance in terms of design or shape.
FIG. 1 shows the housing 5 of a sanitary functional unit 1 in a perspective view. The sanitary functional unit 1 possesses an activating element 3 which is able to be operated by a user and which by rotating or pressing can regulate or block a volumetric flow of liquid. The sanitary functional unit 1 possesses pipelines 7, in the specific case three pipelines 7, wherein two are utilized for the inflow and one is utilized for the outflow. An encircling collar 4 which defines a gripping portion 6 is configured on the housing 5. A housing recess 15 is likewise defined on the housing 5.
FIG. 2 shows a holding element 2 which is fashioned as a holding yoke, in a perspective view. The holding element 2 possesses two yoke springs 28. The holding element 2 can grip the housing 5 at least across half the circumference. The yoke springs 28 are provided for fastening to an external body 18 or a fitting part 26. The thickness of the holding element 2 increases from the inside to the outside, wherein the cross section of the holding element 2 is trapezoidal. The cross section of the holding element 2 may have other shapes, for example be triangular.
FIG. 3 shows another holding element 2 which is fashioned as an annular holder, in a perspective view. The holding element 2 on the inside possesses two protrusions 11 which are disposed so as to be directly mutually opposite, i.e. at an angle of 180°. Two axial grooves 10 are disposed on the external side of the holding element 2, so as to bear on the protrusions 11. The axial grooves 10 have a rectangular or square shape, wherein a trapezoidal shape is also conceivable. External springs 9 which protrude outward are disposed on the external side of the holding element 2. The holding element 2 furthermore possesses two flexible tongues 8 which protrude into the interior part of the holding element 2. Two spring webs 12 which each possess one web bore 16 are on the external edge of the holding element. The flexible tongues 8 are coupled to the spring webs 12 and are mutually contiguous. The holding element 2 possesses an oblique internal face 17.
FIG. 4 shows another holding element 2 which is fashioned as an annular holder, in a perspective view. The holding element 2 from FIG. 4 possesses the same features as the holding element 2 from FIG. 3. The internal sides are identical, and the positioning of protrusions 11 and flexible tongues 8 is identical. The elements on the external side of the holding element 2 in FIG. 4 are mirror-inverted in relation to the elements on the external side of the holding element 2 in FIG. 3. This relates to the external springs and to the spring webs.
FIG. 5 shows another holding element 2 which is fashioned as a holding disk, in a perspective view. The holding element 2 on the internal side possesses two protrusions 11 which are disposed at 180° relative to one another. Flexible tongues 8 which protrude into the internal side of the holding element 2 are fashioned so as to be orthogonal to the protrusions. The holding element 2 possesses fastening bores 24 through which screws 23 are able to be guided in order to be able to fasten the holding element 2 to a receptacle body 25. The holding element has an oblique internal face.
FIG. 6 shows a sanitary functional unit 1 in a perspective view, wherein the housing 5 and the holding element 2 are plugged into one another. The holding element 2 is preferably manufactured from plastics material.
FIG. 7 shows a section through the sanitary functional unit 1 from FIG. 6, wherein the section runs through the flexible tongue 8 and the spring web 12 of the holding element 2. The housing 5 is composed of housing parts 13 which are connected to one another, for example by way of a threaded connection. The housing 5 possesses two encircling collars 4 which are beveled and mutually spaced apart. A collar trench 14 is configured between the encircling collars 4. The encircling collar 4 provides the gripping portion 6. The housing 5 is introduced into the holding element 2 from above, whereby the flexible tongues 8 snap into the collar trench 14. The flexible tongue 8 is supported by an encircling collar 4 at the head end, while the flexible tongue 8 at the foot end bears on the other encircling collar 4. The flexible tongues 8 are manufactured so as to be oversized in relation to the housing 5. Introducing the housing 5 into the holding element 2, and the snap fitting, require a certain use of force, whereby the flexible tongues 8 and the spring web 12 are deformed so as to overcome the geometric obstacle of the oversize. This creates a play-free extraction safeguard which prevents an axial displacement of the housing 5 in relation to the holding element 2. The spring web 12 is deformable in the direction of the web bore 16 bearing thereon. The head side of the flexible tongue 8 is positioned on the spring web 12.
FIG. 8 shows another section through the sanitary functional unit 1 from FIG. 6, wherein the section runs through the axial groove 10 and the protrusion 11. The main axis of the sanitary functional unit 1 is illustrated as a chain-dotted line. The protrusion 11 of the holding element 2 fits exactly into a reciprocating housing recess 15 which is fashioned on the housing 5. The encircling collar 4 cannot be seen here because it is interrupted by the housing recess 15. This here creates a safeguard with slight play which prevents a rotation between the holding element 2 and the housing 5.
FIG. 9 shows a sanitary functional unit 1 in a perspective view, and a section through the external body 18. The holding element 2 and the housing 5 have already been connected to one another. The plug-in direction 22 is symbolized by the arrow. The external body 18 on the internal side possesses an external body shoulder 20, an elongate external body groove 19, and an external body protrusion 30. A resting shoulder 21 is fashioned on one end of the external body groove 19. The number of axial grooves 10 on the holding element 2 corresponds to the number of external body protrusions 30. The number of external body grooves 19 corresponds to the number of external springs 9 on the holding element 2. When plugging-in the external body 18, the external body protrusion 30 fits into the axial groove 10, whereby an anti-rotation safeguard is achieved. The spring web 12 contacts the external body shoulder 20 and is deformed by the latter. The flexible tongue 8 is pressed more intensely in the direction of the housing 5 in the process. The external spring 9 proximal to the foot snaps onto the resting shoulder 21. The bearing action of the external body shoulder 20 on the spring web 12, in conjunction with the bearing action of the external spring 9 on the resting shoulder 21, ensures an extraction safeguard. A permanent connection between the housing 5 and the external body 18 is achieved with the aid of the holding element 2. A sanitary fitting is not required here so that a fastening to a support structure, for example an item of furniture, can be achieved.
FIG. 10 shows a section through the sanitary functional unit 1 which is plugged together with the external body 18, wherein the section runs through the flexible tongue 8 and the spring web 12. As a result of contacting the external body shoulder 20, the spring web 12 is deformed and presses the flexible tongue 8 into the gripping portion 6 of the housing 5 in the process. The flexible tongue 8 is dimensioned so as to be oversized in relation to the gripping portion 6, so that a play-free extraction safeguard is achieved.
FIG. 11 shows another section through the sanitary functional unit 1 which is plugged together with the external body 18, wherein the section has been performed through the external spring 9. This shows how the external spring 9 of the holding element 2 bears on the resting shoulder 21 of the external body 18. The spring web 12 (not illustrated) ensures that the external spring 9 is pressed onto the resting shoulder 21 of the external body 18. The encircling collars 4 are beveled and lie directly on the oblique internal face 17 of the holding element 2. The bevel ensures inter alia that the housing cannot slide downward, whereby the play-free extraction safeguard is guaranteed by the flexible tongue 8 (FIG. 10).
FIG. 12 shows another sanitary functional unit 1 in a perspective view. The assembly is similar to that of FIG. 6; however, the holding element 2 is used here, which is mirror-inverted on the external side. The spring web 12 is disposed on the side of the pipelines 7. The head side of the external springs 9 is likewise disposed on the side of the pipelines 7. The holding element 2 is situated between the pipelines 7 and the activating element 3. The gripping portion 6 is disposed between the activating element 3 and the connector for a water conduit.
FIG. 13 shows a section through the sanitary functional unit 1 from FIG. 12, wherein the section has been performed through the flexible tongue 8 and the spring web 12. The foot side of the flexible tongue 8 is disposed on the spring web 12, and is thus mirror-inverted in relation to the exemplary embodiment in FIG. 7. The explanations pertaining to FIG. 7 apply here in an analogous manner.
FIG. 14 shows another section through the sanitary functional unit 1 from FIG. 12, wherein the section has been performed through the protrusion 11 of the holding element 2. The explanations and reference signs apply in an analogous manner as in FIG. 8.
FIG. 15 shows a sanitary functional unit 1 in a perspective view, and a section through the external body 18. The plug-in direction 22 is illustrated by the arrow. The head side of the external spring 9 and the spring web 12 of the holding element 2 are positioned in the plug-in direction 22. The external body 18 possesses an external body groove 19, an external body shoulder 20, an external body protrusion 30 and a resting shoulder 21. The number of external body grooves 19 corresponds to the number of external springs 9. The number of external body protrusions 30 corresponds to the number of axial grooves 10.
FIG. 16 shows a section through the assembled module from FIG. 15, wherein the section has been performed through the flexible tongues 8 and the spring web 12. The spring web 12 is pressed against the external body shoulder 20 and simultaneously presses the flexible tongue 8 into the gripping portion 6. The flexible tongue 8 is manufactured so as to be oversized in relation to the housing 5. A certain plug-in force is required in order for the holding element 2 and the housing 5 to be connected. The flexible tongue 8 is coupled to the spring web 12. Two encircling collars 4 which are beveled can be seen. The flexible tongue 8 proximal to the head contacts the one encircling collar 4 and proximal to the foot bears on the other encircling collar 4.
FIG. 17 shows another section through the sanitary functional unit 1 which is plugged together with the external body 18, wherein the section has been performed through the external spring 9. The oblique internal face 17 of the holding element 2 is disposed so as to be an exact fit with the beveled encircling collars 4. The snap-fit of the external springs 9 on the resting shoulder 21 leads to the sanitary functional unit being permanently fastened to the external body.
FIG. 18 shows a holding element 2 which is fashioned as an annular holder, in a perspective view from transversely above. This here is the same holding element from FIG. 3, or which is illustrated in FIGS. 6 to 8. FIG. 19 shows a view from below of the holding element 2 of FIG. 18. FIG. 20 shows a view from above of the holding element 2 from FIG. 18. FIG. 21 is a perspective view from transversely below of the holding element 2 from FIG. 18.
FIG. 22 shows another holding element 2 in a perspective view from transversely above. FIG. 23 shows the holding element 2 in a perspective view from transversely below. The holding element 2 is identical to the holding element 2 from FIG. 4, or from FIGS. 15 to 17.
FIG. 24 shows an exploded illustration of an assembly module of a sanitary functional unit 1 having a holding element 2 which is fashioned as a holding disk. The holding element 2 has four fastening bores 24 through which screws 23 are able to be guided. The holding element 2 is connected to the housing 5. The sanitary functional unit 1 is connected to pipelines 7 which enable a connection to a water conduit. The holding element 2 can be connected to a receptacle body 25 using the screws 23. The assembling of such a structure in which a holding disk is used is somewhat more time-intensive than the assembling of a structure in which holding elements 2 which are fashioned as annular holders or holding yokes are used.
FIG. 25 shows the assembly module from FIG. 24 in a plugged-together state.
FIG. 26 shows a section through the assembly module from FIG. 25, wherein the section has been performed through the flexible tongue 8 and the receptacle body 25. Two encircling collars 4 are configured on the housing 5, whereby the collars 4 are beveled. The flexible tongue 8 protrudes inward in the direction of the housing 5. The flexible tongue 8 proximal to the head contacts the one encircling collar 4, while said flexible tongue 8 proximal to the foot bears on the other encircling collar 4. The flexible tongue 8 in the gripping portion 6 is manufactured so as to be oversized in relation to the housing 5, so that a certain force has to be overcome in order to connect the holding element 2 and the housing 5. This creates a deformation on the holding element 2 when this force is overcome. The flexible tongues 8 ensure an extraction safeguard which is fashioned to be free of play.
FIG. 27 shows another section through the assembly module from FIG. 25, wherein the section has been performed through the protrusions 11 on the holding element 2. The housing is not illustrated in a section in FIG. 27.
FIG. 28 shows an enlarged illustration of the sub-region of FIG. 27, wherein the housing 5 and the protrusion 11 can be seen. The two encircling collars 4 can likewise be seen, whereby the collars 4 are very flat in this region because the housing 5 here has a housing recess 15. It is also possible for the collars 4 to be completely absent in the housing recess 15. The collars 4 are not beveled in the region of the housing recess 15.
FIG. 29 shows another assembly module in an exploded illustration, having a detached holding element 2. The holding element 2 here is fashioned as a holding yoke. The sanitary functional unit 1 lies on a fitting part 26. A knob 27 is able to be connected to the activating element 3, whereby a user can operate the activating element 3 by manipulating the knob 27. The fitting parts 26 have burlings and notches so that the fitting parts 26 are able to be connected to one another and plugged into one another. The gripping portion 6 is configured on the housing 5 and is provided by the encircling collar 4. The function of the holding element 2 lies in achieving an extraction safeguard in the axial direction of the sanitary functional unit 1.
FIG. 30 shows the assembly module from FIG. 29 having a plugged-in holding element 2. The holding element 2 is configured as a holding yoke. The holding element 2 has two yoke springs 28 which can engage on fitting arms 29 on the fitting part 26. The plugged-in holding element 2 can be unplugged again by mutually compressing the yoke springs 28.
FIG. 31 shows a section through the holding element 2 of a plugged-together assembly module from FIG. 30. The holding element 2 possesses two yoke springs 28. The fitting part 26 possesses two fitting arms 29, whereby the yoke springs 28 are configured in such a manner that the latter can engage on the fitting arms 29. The fitting parts 26 lie on top of one another and are connected to one another by the burlings and notches (not visible here). The yoke springs 28 can latch into the fitting arms 29 of the fitting part 26, so that the sanitary functional unit can be prevented from falling out.
FIG. 32 shows a section through the plugged-together assembly module from FIG. 30.
FIG. 33 shows a section through the plugged-together assembly module from FIG. 30, wherein the sectional direction is indicated by the arrows in FIG. 32. A tongue-and-groove assembly is configured between the fitting part 26 and the housing 5.
FIG. 34 shows an enlargement of a sub-region from FIG. 32 (round region). The holding element 2, configured as a holding yoke, engages on the housing 5 in a gripping portion 6 which is provided by the encircling collars 4. The encircling collars 4 are beveled. The holding yoke has a thickness which increases from the inside to the outside. The cross section of the holding yoke is trapezoidal. Other cross-sectional shapes, for example triangular, are likewise conceivable. The holding element 2 is configured so as to be oversized in relation to the housing 5 and in particular in relation to the encircling collar 4. The width of the collar trench 14 here is between the minimum and the maximum thickness of the holding yoke, so that an adaptation which eliminates the play takes place. Therefore, the holding yoke does not bear directly on the collar trench 14, which is delimited by the two encircling collars 4, but floats above said collar trench 14 so to speak. A play-free safeguard in relation to extraction and falling out is achieved by the oversize.
In a sanitary functional unit having a housing and a holding element which at least in portions encompasses the housing it is proposed that the holding element contacts the housing in a gripping portion and in this gripping portion is manufactured so as to be oversized in relation to the housing.
