Abstract

A multi-part cartridge adapter (1) is proposed, comprising a base body (3) and an adapter part (4) which can be detachably connected to one another, wherein a contact force (10) of a cartridge (14) connected to the adapter part (4) on one cartridge side (5) is transmitted via a support area (9) from the adapter part (4) to a sanitary fitting (16) and / or wherein different adapter parts (4) can be combined with a common base body (3) by means of variable cartridge-side connection openings (12) and constant base-side connection openings (13).

Description

[0001] The invention relates to a cartridge adapter with a base body having at least one hose connection and an adapter part detachably connected thereto, wherein the adapter part has a cartridge side and a base body side, wherein the base body side has a contact area for contact with the base body.

[0002] The invention further relates to a cartridge adapter with a base body having at least one hose connection and an adapter part detachably connected thereto, wherein the adapter part has a cartridge side and a base body side, wherein the base body side has a contact area for contact with the base body, wherein the cartridge side and the base body side preferably have connection openings connected fluidically to each other in pairs.

[0003] The invention also relates to a set of different adapter parts that can be detachably connected to a common base body of a cartridge adapter and have a cartridge side and a base body side with connection openings.

[0004] The invention further relates to a series of cartridge adapters, wherein at least two variants have a matching base body and different adapter parts.

[0005] The invention further relates to the use of an adapter part, wherein the adapter part can be detachably connected to a base body to form a claimed cartridge adapter.

[0006] The invention relates to a sanitary fitting with a claimed cartridge adapter.

[0007] Cartridge adapters, especially one-piece cartridge adapters, are known from practical use and serve to connect a valve cartridge fluidically to hoses. For this purpose, the known hose connectors have a contact surface against which the valve cartridge can fit tightly, with connection openings corresponding to the inlets and outlets of the valve cartridge being formed in the contact surface, each of which is fluidically connected to a hose connector.

[0008] Valve cartridges often provide a mixing function for blending hot and cold water and a flow control function for adjusting the flow rate. The corresponding cartridge adapters therefore have three hose connections, for example, for pressurized hot and cold water hoses and a mixed water hose designed for low pressure.

[0009] Such valve cartridges can be designed, for example, as single-lever mixing cartridges or as rotary push-button valves.

[0010] The invention is based on the objective of improving the interchangeability and / or variability of at least one component of the cartridge adapter by making the cartridge adapter multi-part.

[0011] To solve the problem, the features of claim 1 are provided according to the invention. In particular, to solve the aforementioned problem in a cartridge adapter of the type described above, it is proposed that a support area be formed outside the contact area on the base body side to support a contact force applied to the cartridge side.

[0012] For example, the support area can be positioned laterally, particularly in relation to the insertion direction of the adapter part and / or the cartridge. This allows for easy access.

[0013] The support area can be designed, for example, as a projection, in particular a support ring, support collar, or at least a support mandrel. This allows for the simple application of a clamping force to a valve component.

[0014] The basic body can, for example, have three hose connections, in particular a cold water hose connection, a hot water hose connection and a mixed water hose connection.

[0015] The main body can, for example, be formed within the main pipe of a sanitary fitting and project, at least partially, into a cartridge chamber of the sanitary fitting. Furthermore, the adapter part is formed within the cartridge chamber and can interact with the section of the main body that projects into the cartridge chamber.

[0016] Once the base body and the adapter part are positioned within the sanitary fitting, a cartridge can be screwed into the cartridge chamber of the sanitary fitting, which exerts the contact force on the cartridge side of the adapter part. To advantageously prevent the contact force applied by the cartridge to the cartridge side of the adapter part from being directly transferred to the base body, the support area is designed outside the contact area between the base body side of the adapter part and the base body. This support area is preferably formed by the sanitary fitting itself, in particular by a section within the cartridge chamber of the sanitary fitting.

[0017] A further advantage is that this allows for higher fatigue strength of the base body, as it is not directly stressed in the contact area with the adapter part. Furthermore, higher fatigue strength of the adapter part can also be ensured, since the contact force applied by the screwed-on cartridge does not cause wear on any contact surface of the adapter part that is in contact with a contact surface of the base body in the contact area. For example, the material of the adapter part can be reinforced in the support area.

[0018] Alternatively or additionally, the features of claim 2 are provided according to the invention to solve the aforementioned problem. In particular, to solve the aforementioned problem in a cartridge adapter of the type described above, it is proposed according to the invention that at least one cartridge-side connection opening is offset from at least one (in particular the fluidically connected) base body-side connection opening. The connection patterns on both sides of the adapter part are thus configured differently from each other.

[0019] In particular, all cartridge-side connection openings are offset from the base-side connection openings. The connection patterns can be transformed into one another by a combination of rotation, translation, mirroring and / or compression / stretching, or a different design can be implemented, especially while maintaining a fluidic correspondence of the outlet patterns.

[0020] A cartridge-side connection opening is characterized, for example, by the fact that it faces the cartridge.

[0021] The term "offset" can be understood, for example, to mean that the cartridge-side connection openings are located in a different position than the base-side connection openings, whereby the cartridge-side connection openings are nevertheless connected to the base-side connection openings and each pair forms a common fluid path. Thus, for example, it can be provided that three cartridge-side connection openings are each offset from one another, with each cartridge-side connection opening being fluidically connected to a base-side connection opening, and the base-side connection openings themselves being offset from each other and from the cartridge-side connection openings.

[0022] The offset arrangement of the connection openings can, for example, lead to connection patterns on both sides that cannot be mapped onto each other by a rotation, and / or to connection patterns that are connected to each other by fluidic lines that cross each other.

[0023] This makes it particularly advantageous to generate variability in the adapter parts, as these can be adapted to the connection openings of the cartridge on the cartridge side, while the connection openings on the base body side can have constant connection openings and those adapted to the connection openings of the base body.

[0024] Thus, for example, it may be provided that cartridges with different zero positions of an adjusting lever, in particular for example 0°, 45°, 50°, only require different adapter-side connection openings, while base-side connection openings can be the same and designed to match connection openings of the base body.

[0025] This allows for the highly advantageous achievement that only different adapter parts, tailored to the specific cartridge, are required for different cartridges, while the base body can remain the same. This is achieved in particular by ensuring that the connection openings on the base body are independently aligned with the connection openings on the cartridge side.

[0026] Advantageously, the cartridge-side connection openings can also be adapted to different cartridge locking mechanisms.

[0027] In a further advantageous embodiment of the invention, it can be provided that the connection openings on the base body can be detachably connected to the base body and the connection openings on the cartridge side can be detachably connected to a cartridge.

[0028] This design offers a particularly advantageous way to create a multi-part cartridge adapter whose components, such as the base body and / or the adapter part, can be independently replaced and / or modified. Furthermore, it is advantageous that a fluid path can be defined by connecting the cartridge-side connection openings to the cartridge and the base body connection openings to the base body. The detachable connection of the components also facilitates the removal of the cartridge adapter.

[0029] In a further advantageous embodiment of the invention, it can be provided that the adapter part overlaps the base body.

[0030] For example, it may be provided that the adapter part overlaps the base body on a radial outer circumference, for example only in sections, outside the contact area.

[0031] This can be extremely advantageous, for example, to ensure that no force component of the pressure force of the cartridge acting on the adapter part is transferred to the base body.

[0032] Another advantageous embodiment of the invention may provide that the support area is designed to be supported on a bearing surface of the sanitary fitting.

[0033] For example, the contact surface of the sanitary fitting can be designed to limit and / or define the cartridge chamber(s), such as the cartridge chamber already described, and in particular the transition from the cartridge chamber to the main pipe, such as the main pipe of the sanitary fitting already described. This advantageously transfers the contact force from the cartridge to the adapter part and, via the support area of ​​the adapter part, directly to the stable sanitary fitting.

[0034] In particular, the contact surface is not round.

[0035] For example, the contact surface of the sanitary fitting can be designed to be non-circular and the support area of ​​the adapter part round, or vice versa, i.e., the contact surface round and the support area non-circular. This can be extremely advantageous because not the entire circumferential section of the adapter part, which can form the support area, is in contact with the contact surface and is therefore at least partially unloaded.

[0036] However, it may also be intended, for example, that the support area of ​​the adapter part and the contact surface of the sanitary fitting are designed to be non-circular or round.

[0037] In a further advantageous embodiment of the invention, it can be provided that the base body has a suspension structure by means of which the base body can be suspended in a holding structure of the sanitary fitting.

[0038] For example, the mounting structure can be designed to be formed only partially on the base body. Particularly advantageous is the ability to achieve a minimal contact area with the sanitary fitting's retaining structure by mounting the mounting structure only partially on the base body, for example, by forming a projection.

[0039] Furthermore, the retaining structure of the sanitary fitting can be formed by a projection that is matched to the mounting structure and located within or bordering the cartridge chamber, forming a suitable counterpart to the mounting structure of the base body. This allows the base body to be easily and detachably connected to the sanitary fitting, which is particularly advantageous.

[0040] This also simplifies the installation of the base body, as it can thus be inserted into the sanitary fitting via the main pipe, for example, and the hanging structure, which is formed at least partially on a radial outer circumference of the base body, can be hooked into the holding structure and thus detachably connected to the sanitary fitting.

[0041] It may also be provided, for example, that the retaining structure of the sanitary fitting is formed by at least one circumferential section of the previously described bearing surface of the sanitary fitting. In such a design, the circumferential section of the bearing surface into which the retaining structure of the base body is suspended does not form a support area in this region.

[0042] In a further advantageous embodiment of the invention, it can be provided that the adapter part holds the base body in its installation position.

[0043] For example, it can be provided that the base body, which is suspended in the mounting structure of the sanitary fitting via the hanging mechanism, can be locked, fixed, and / or finally positioned by installing the adapter part via the contact in the contact area. This is particularly advantageous because no additional elements are needed to hold the base body in its installation position.

[0044] The "installation position" can be considered the position of the base body in which a fluidic connection between the base body and the adapter part is possible. This is particularly the case when the connection openings of the adapter part on the base body coincide with connection openings of the base body in such a way that leakage of a fluid, especially water, flowing from the base body to the adapter part due to misaligned fluid paths is largely prevented.

[0045] In a further advantageous embodiment of the invention, it can be provided that a transition between the base body and the adapter part is fluidically sealed, in particular by means of a radial seal.

[0046] The fluidic seal can be formed, for example, by an O-ring. Other sealing elements are also conceivable.

[0047] The transition can be formed, for example, by the contact area. It can be provided, for instance, that the connection openings on the base body, which are directly connected to the base body, are fluidically sealed in such a way that leakage in this area, particularly in the contact area, can advantageously be prevented.

[0048] Alternatively or additionally, it may be provided that a transition to the connection openings and / or a transition to the at least one hose connection is fluidically sealed, in particular by means of a radial seal.

[0049] This also prevents leaks at the respective transitions between the components. It is particularly advantageous if all transitions—that is, the transition from a hose connected to the main body's hose connection, the transition from the main body to the adapter part, and the transition from the adapter part to the cartridge—are fluidically sealed. Therefore, it can be provided that the main body-side connection openings and the cartridge-side connection openings are fluidically sealed, in particular by means of a radial seal.

[0050] In a further advantageous embodiment of the invention, it can be provided that the adapter part has a circumferential seal on the outside.

[0051] "Outside" can mean that the adapter part is sealed all around its radial outer circumference.

[0052] The seal can be formed, for example, by an O-ring, although other sealing elements are also possible.

[0053] It is particularly advantageous to prevent the fluid, especially water, from escaping from the cartridge adapter, for example into the cartridge chamber, and thus from flowing back into the main pipe of the sanitary fitting, even if a leak exists, for example at the transition from the base body to the adapter part.

[0054] For example, it may also be provided that, instead of the external seal, the retaining structure of the sanitary fitting and / or the bearing surface of the sanitary fitting is sufficiently large so that backflow of the fluid into the main pipe can be prevented in the event of a leak.

[0055] In a further advantageous embodiment of the invention, it can be provided that a seal, for example the aforementioned seal, of the adapter part seals a transition to the or a sanitary fitting, for example the aforementioned sanitary fitting.

[0056] This is particularly advantageous, for example, in the event of a leak between the cartridge and an adjacent area through which a fluid, especially water, flows during operation (e.g., at the cartridge's connection openings), preventing water escaping through the leak from running under a washbasin or sink. Furthermore, it generally prevents water from flowing against the intended direction and entering areas within the sanitary fitting.

[0057] In general, it can be said that the aforementioned seal creates a watertight seal between the cavity of the sanitary fitting (for example, the main pipe) that accommodates the hoses connected to the cartridge and the cartridge compartment.

[0058] In a further advantageous embodiment of the invention, it can be provided that the adapter part has at least one orientation lug.

[0059] The orientation lug can be inserted, for example, into a recess, such as a drain channel, of the sanitary fitting. This is particularly advantageous for achieving optimal orientation of the adapter part within the sanitary fitting, especially within the cartridge chamber, such as the cartridge chamber already described. For instance, the orientation lug can be designed to be present on the adapter part specifically when it carries the previously described and / or stressed external seal. Even then, the drain channel on the sanitary fitting can still be used for orientation, as it does not extend to the end of the cartridge chamber where the seal, such as a piston or O-ring, is positioned in its operating position.

[0060] In a further advantageous embodiment of the invention, it can be provided that the adapter part is interchangeable and / or its design can be varied to allow connection with different cartridges.

[0061] This can be achieved particularly well if the connection openings on the base body of the adapter part are consistent and designed to fit the base body, and only the connection openings on the cartridge side can be varied. This makes it especially advantageous to connect different cartridges with different adapter parts, but with the same base body.

[0062] Because the adapter part is detachably connected to the base body, the adapter part can also be easily replaced without having to remove the entire cartridge adapter.

[0063] In a further advantageous embodiment, the invention may provide that the at least one hose connection is aligned at an angle to a connection direction between the base body and the adapter part.

[0064] For example, the connection direction between the base body and the adapter part may be perpendicular to the at least one hose connection of the base body. Alternatively, the angle between the connection direction and the at least one hose connection of the base body may be more or less than 90°.

[0065] Deflection of the fluid, especially water, can therefore be particularly advantageous.

[0066] In a further advantageous embodiment of the invention, it can be provided that the at least one hose connection is aligned longitudinally to a connection direction between the base body and the adapter part.

[0067] The term "longitudinal" can, for example, be understood in the sense of the claim to mean that there is no angle formed between the at least one hose connection of the base body and the connection direction between the base body and the adapter part.

[0068] The cartridge adapters are therefore particularly advantageous as they can be used without restriction on a wide variety of sanitary fittings.

[0069] Alternatively or additionally, the features of the dependent claim directed to a set are provided according to the invention to solve the aforementioned problem. In particular, a set of different adapter parts is thus proposed to solve the aforementioned problem. These adapter parts are detachably connectable to a common base body of a cartridge adapter and have a cartridge side and a base body side with connection openings, wherein the base body-side connection openings of the adapter parts are aligned with connections of the base body, and wherein the adapter parts differ in the design of their cartridge-side connection openings.

[0070] The adapter parts can, for example, be various adapter parts of different designs that have already been described. The base body can also be, for example, the base body that has already been described.

[0071] Because the different adapter parts differ only in the design of their cartridge-side connection openings, which are advantageously compatible with different cartridges, particularly fluidic ones, but are identical in the design of their base-side connection openings and matched to the base's connections, all adapter part variants can be connected to the same base. This results in excellent adaptability of the adapter parts to different cartridges without having to remove the base as part of the cartridge adapter when changing cartridges and / or the adapter part. This allows for variability and / or easy interchangeability of the adapter parts.

[0072] For example, it may be planned that a 45° version of the cartridge's operating lever is to be installed in the sanitary fitting instead of a 0° version. In this case, it is no longer necessary to remove the entire cartridge adapter and adapt it from the 0° version to the 45° version, but only the adapter part with the corresponding cartridge-side connection openings, which are matched to the cartridge variant.

[0073] The cartridge-side connection openings can therefore differ, for example, in their position and / or orientation on the cartridge side.

[0074] In a further advantageous embodiment, it can be provided that the adapter parts differ by different connection patterns on the cartridge side.

[0075] Different connection patterns can be characterized, for example, by differently arranged, positioned and / or oriented cartridge-side connection openings, whereby each connection pattern of the adapter part is advantageously matched to a connection pattern of a cartridge to be connected to the adapter part.

[0076] Alternatively or additionally, the features of the dependent claim, which relates to a series of products, are provided according to the invention to solve the aforementioned problem. In particular, a series of cartridge adapters is thus proposed to solve the aforementioned problem, wherein at least two variants have a matching base body and differing adapter parts, in particular wherein each variant is a previously claimed cartridge adapter and / or wherein the adapter parts of different variants form a previously claimed set.

[0077] The cartridge adapters can, for example, be formed from a base body and an adapter part detachably connected to it, as already described and / or claimed. The differing adapter parts can, for example, only differ in the design of their cartridge-side connection openings. These cartridge-side connection openings can be the ones already described. To allow the at least two variants of cartridge adapters to be detachably connected to the same base body, they have identical connection openings on the base body. These connection openings on the base body can also be the ones already described.

[0078] Particularly advantageous can be achieved with the cartridge adapters, as already described, with one outstanding advantage of the series being that each cartridge adapter in the series does not require its own base body.

[0079] In a further advantageous embodiment, it can be provided that the adapter parts have different connection patterns on the cartridge side of the adapter parts.

[0080] The connection diagrams can be the connection diagrams already described, which in turn allows for the previously described advantages to be achieved.

[0081] Alternatively or additionally, to solve the aforementioned problem, the features of the dependent claim, which relates to the use of an adapter part, are provided according to the invention. In particular, the use of an adapter part is thus proposed, wherein the adapter part is detachably connectable to a base body to form a cartridge adapter as already claimed.

[0082] The detachable connection between the base body and the adapter part allows for the previously described advantages to be achieved.

[0083] Alternatively or additionally, the features of the dependent claim, which relates to a sanitary fitting, are provided according to the invention to solve the aforementioned problem. In particular, a sanitary fitting with a cartridge adapter already claimed is thus proposed according to the invention, especially wherein the adapter part is supported on a fitting body, bypassing the base body.

[0084] The fitting body can, for example, be a section within the or a cartridge compartment, such as the one already mentioned.

[0085] Particularly advantageous can be achieved by using a sanitary fitting with the previously described cartridge adapter, generating the benefits already described.

[0086] In a further advantageous embodiment, it can be provided that the sanitary fitting has a holding structure into which the suspension structure of the base body of the cartridge adapter is suspended, at least partially.

[0087] This makes it particularly advantageous that the base unit can be easily and detachably connected to the sanitary fitting. The mounting structure can, for example, be the one already described, which in turn achieves the advantages already mentioned.

[0088] Alternatively or additionally, it may be provided that the support structure forms at least a section of the support area.

[0089] For example, the suspension structure of the base body, such as a projection or a projection, can be suspended in a section of the support area. This makes it particularly advantageous to eliminate the need for an additional support structure.

[0090] In a further advantageous embodiment, the retaining structure can be designed in such a way as to prevent a fluid from flowing back into a main pipe of the sanitary fitting.

[0091] The main pipe of the sanitary fitting can be the main pipe already described, in which the base body of the cartridge adapter is formed. The fluid can be water.

[0092] The retaining structure can, for example, have an extended radial inward reach, preventing fluid from penetrating back into the main pipe even if the cartridge adapter leaks. This makes it particularly advantageous to forgo an external circumferential seal on the adapter part.

[0093] It may also be provided, for example, that not the holding structure, but alternatively or additionally the contact surface of the sanitary fitting on which the support area of ​​the adapter part rests, is designed in such a way as to prevent backflow of the fluid.

[0094] In a further advantageous embodiment of the invention, it can be provided that at least one seal is formed which seals a transition from the cartridge adapter to the sanitary fitting.

[0095] The seal in question could be the seal already described.

[0096] This is extremely advantageous as it prevents the fluid, for example water, from flowing back into poorly accessible areas within the sanitary fitting in the event of a leak or leakage, and / or from escaping through backflow below a sink and / or washbasin, generally at points that are not primarily sealed by fluids.

[0097] In particular, the seal seals the transition from the cartridge adapter to the sanitary fitting in such a way that in the event of a leak, fluid is forced to escape through an insertion opening of a cartridge chamber that accommodates the cartridge adapter.

[0098] The fluid leakage could be water leakage, which can occur, for example, due to wear and / or improper assembly of the cartridge adapter with the cartridge.

[0099] In addition to the already described advantage of preventing water from flowing into areas inside and / or outside the sanitary fitting, it can also be made possible for the escaping water to exit into a predefined area, namely the insertion opening.

[0100] The invention will now be described in more detail with reference to exemplary embodiments, but is not limited to these embodiments. Further exemplary embodiments result from combining the features of one or more claims with each other and / or with one or more features of the exemplary embodiment.

[0101] It shows, in a highly simplified representation, Fig. 1 a schematic, three-dimensional representation of a cartridge adapter, consisting of a base body and an adapter part detachably connected to it, Fig. 2 a schematic sectional view of a cartridge adapter which is installed in a sanitary fitting, Fig. 3 a schematic sectional view of a cartridge adapter which is installed in a sanitary fitting and connected to a cartridge, Fig. 4 a schematic sectional view of a cartridge adapter which is installed in a sanitary fitting and connected to a cartridge, wherein the adapter part has a seal on the outside, Fig.Fig. 5 a schematic representation of two different adapter parts of a cartridge adapter, Fig. 6 a schematic sectional view of a cartridge adapter, wherein the at least one hose connection is aligned longitudinally to a connection direction between the base body and the adapter part, wherein the adapter part is supported on the base body, Fig. 7 a schematic sectional view of a cartridge adapter, wherein the at least one hose connection is aligned longitudinally to a connection direction between the base body and the adapter part, wherein the adapter part is supported on the sanitary fitting.

[0102] Fig. 1Figure 1 shows a cartridge adapter, designated as a whole by 1, comprising a base body 3 and an adapter part 4 detachably connected to it. In this embodiment, the base body 3 has three hose connections 2: a mixed water hose connection 2', a hot water hose connection 2" and a cold water hose connection 2'. The hose connections 2 are oriented at an angle to a connection direction 23 between the base body 3 and the adapter part 4.

[0103] Each hose connection 2 accommodates a hose 34. The hoses 34 are equipped at least at one end with appropriate fittings that fit into the respective hose receptacle 2.

[0104] The adapter part 4 further comprises a cartridge side 5 and a base body side 6. The cartridge side 5 and the base body side 6 each have, in this case, three connection openings 11, wherein the connection openings 11 of the cartridge side 5 form cartridge-side connection openings 12 and the connection openings 11 of the base body side 6 form base body-side connection openings 13. In the illustrated embodiment, the base body-side connection openings 13 of the adapter part 4 are concealed by the base body 4 itself, but are, in the embodiment shown, Fig. 5 Described and shown in more detail.

[0105] Fig. 2 shows a cross-section of the cartridge adapter 1 according to Fig. 1in a state installed in a valve body 26 of a sanitary fitting 16. Functionally and / or structurally similar or identical components and functional units to the preceding embodiment are designated with the same reference numerals and are not described separately again.

[0106] The base body 3 is formed within a main tube 27 of the valve body 26 and projects, at least partially, into a cartridge chamber 28. The base body 3 is suspended in a retaining structure 18 of the sanitary fitting 16 via an externally formed, partially formed suspension structure 17, here a projection 17'. The retaining structure 18 is formed by a radially inwardly extending circumferential section 18', which delimits the cartridge chamber 28.

[0107] The seal 21 closes the cavity of the main tube 27, which accommodates the hoses 34, fluidically tight against the cartridge chamber 28.

[0108] Furthermore, it is shown that the base body side 6 of the adapter part 4 has a contact area 7 for a contact 8 with the base body 3. This additionally holds the base body 3 in its installation position. It can therefore be said that the adapter part 4 holds the base body 3 in its installation position.

[0109] It is further shown that the connection openings 11 in the illustrated embodiment are fluidically connected to each other in pairs and that the cartridge-side connection openings 12 are offset from the base-side connection openings 13. It can therefore be said that the offset arrangement of the connection openings 11 results in different connection patterns 25 on the base-side 6 and the cartridge-side 5, which cannot be mapped onto each other by rotating the adapter part 4 and which are connected to each other inside the respective adapter part 4 by intersecting fluidic channels 30.

[0110] Fig. 2 It can also be seen that the connection openings 13 on the base body are aligned with connections 24 of the base body 3.

[0111] Fig. 3 In contrast to the previous embodiment, this shows that a cartridge 14 is screwed into the cartridge chamber 28 of the sanitary fitting 16. It is evident that the connection openings 13 on the base body are detachably connected to the base body 3 and the connection openings 12 on the cartridge side are detachably connected to the cartridge 14.

[0112] By screwing the cartridge 14 into the cartridge chamber 28, a contact force 10 is applied to the adapter part 4. To prevent the contact force 10 from being transferred from the adapter part 4 to the base body 3, a support area 9 is formed outside the contact area 7 on the base body side 6 to support the contact force 10 applied to the cartridge side 5. The support area 9 on the base body side 6 is designed to support a non-circular contact surface 15 of the sanitary fitting 16. It can therefore be said that the adapter part 4 is supported on the fitting body 26, bypassing the base body 3. Furthermore, it can be seen that the support area 9 is arranged laterally, here with respect to a insertion direction 23', between the adapter part 4 and the cartridge 14. The support area 9 is designed as a projection 9', here as a support ring 9".In further embodiments, the support area 9 can be designed as a support ring and / or support mandrel.

[0113] The support surface 15, particularly in the illustrated embodiment, at least partially provides the retaining structure 18 into which the suspension structure 17 of the base body is suspended. The support surface 15 is thus also formed by the radially inwardly projecting circumferential section 18' of the sanitary fitting 16. Furthermore, in the illustrated embodiment, the retaining structure 18 is designed such that backflow of a fluid (not shown) into the main pipe 27 is prevented.

[0114] In the exemplary embodiments according to the Fig. 2 and 3It is further evident that the adapter part 4 overlaps the base body. It is also shown that a transition 19 between the base body 3 and the adapter part 4, a transition 19 to the connection openings 11, and a transition 11 to the hose connections 2 are each fluidically sealed via a radial seal 20.

[0115] Fig. 4 In contrast to the previous embodiment, according to Fig. 3 that the adapter part 4 additionally has a circumferential seal 21 on its outer side, here an O-ring 21', via which a transition 19' to the sanitary fitting 16 is sealed. It can therefore be said that at least one seal 21 is formed which seals a transition 19' from the cartridge adapter 1 to the sanitary fitting 16 (see also Fig. 6 and Fig. 7The seal 21 seals the transition 19' in such a way that in the event of a leak, fluid escapes through an insertion opening 33 of the cartridge chamber 28 accommodating the cartridge adapter 1 (in Fig. 3 (shown) is forced. For better clarity, the embodiment shown in the example is as follows. Fig. 4 , which are identical components to the embodiment shown in the Fig. 3 not all components are marked with a reference symbol. Fig. 5 In contrast to the preceding embodiments, this figure shows two different variants of adapter parts 4 of a cartridge adapter 1, which can be detachably connected to a common base body 3 in a front view without a cartridge 14. Both adapter parts 4 have an orientation lug 22, which can be inserted into a drainage channel 29 of the cartridge chamber 28 and positioned thereby.

[0116] The left-hand illustration I shows the connection diagram 25 on the cartridge side 5 of a first adapter part 4. The connection diagram 25 is characterized by three cartridge-side connection openings 12. The connection diagram 25 shown in the left-hand illustration I, and thus the arrangement of the cartridge-side connection openings 12, is suitable, for example, for connecting a cartridge (not shown in detail here) with a 0° adjusting lever. Furthermore, the base-side connection openings 13 are shown at the very bottom of the left-hand illustration I, which lead to connections 24 (not shown in detail here) (see [reference]). Figs. 2 to 4 ) of the basic body 3 are aligned.

[0117] The right-hand illustration II, however, shows another connection diagram 25 of a second variant of an adapter part 4 of a cartridge adapter 1. The cartridge-side connection openings 12 are offset by 45° compared to the variant of the left-hand illustration I, which allows a cartridge 14 (not shown in detail here) to be connected to the cartridge side 5 with a 45° adjusting lever.

[0118] The connection openings 13 on the base body are also shown below the front view in the right-hand illustration. Comparing the connection openings 13 on the base body, or rather the connection diagrams 25 of the base body side 6, in the left-hand illustration I with the right-hand illustration II, it is evident that they do not differ. Therefore, the adapter part 4 of the right-hand illustration II can also be detachably connected to the base body 3 of the left-hand illustration, since the adapter parts 4 differ only in their connection diagrams 25 on the cartridge side 5.

[0119] It can therefore be said that the different variants form a set of different adapter parts 4 which can be detachably connected to a common base body 3 of the cartridge adapter 1 and have a cartridge side 5 and a base body side 6 with connection openings 11, wherein base body-side connection openings 13 of the adapter parts 4 are matched to connections 24 of the base body 3 and wherein the adapter parts 4 differ in their design of cartridge-side connection openings 12.

[0120] Furthermore, because the two variants of cartridge adapters 1 shown here can have a matching base body 3 and different adapter parts 4, a series of cartridge adapters 1 is formed.

[0121] Fig. 6Figure 1 shows a further embodiment of a cartridge adapter 1, wherein the hose connections 2 are aligned longitudinally to the connection direction 23 between the base body 3 and the adapter part 4. It is also shown that the support area 9 is located in the contact area 7. Furthermore, the adapter part 4 is surrounded on the outside by a section 32 of the base body 4 extending in the longitudinal direction 31. Seals 21 are also formed at the transition 29 between the adapter part 4 and the base body 3. The section 32 of the base body extending in the longitudinal direction 31 also carries a circumferential radial seal 20.

[0122] Fig. 7 In contrast to the preceding embodiment, this shows that the contact force 10 is not transferred to the base body 3, but that the adapter part 4, according to the embodiment shown, Figs. 1 to 5 , in support area 9 on the valve body 26 of the sanitary fitting 16.

[0123] A multi-part cartridge adapter 1 with a base body 3 and an adapter part 4, which can be detachably connected to each other, is thus proposed, wherein a contact force 10 of a cartridge 14 connected to the adapter part 4 on a cartridge side 5 is transferred via a support area 9 from the adapter part 4 to a sanitary fitting 16 and / or wherein different adapter parts 4 with a common base body 3 can be combined by means of variable cartridge-side connection openings 12 and constant base-side connection openings 13.
