Description

[0001] The invention relates to a connection part for a sanitary installation, wherein the connection part has a hose receptacle, an outlet opening, and a contact surface for an aerator. The contact surface can, in particular, be designed as a sealing surface. Furthermore, the contact surface can, in particular, surround the outlet opening of the connection part. Such a connection part is known in practice.

[0002] The invention further relates to a method for inserting a connection part, in particular the connection part described herein, into a sanitary fitting. Methods for inserting a connection part into a sanitary fitting are also known in practice.

[0003] The invention also relates to a sanitary installation arrangement comprising an aerator and a connection part which is positioned upstream of the aerator in the direction of flow, wherein the connection part has a hose receptacle. Such a sanitary installation arrangement is known in practice.

[0004] The invention further relates to the use of an internal thread. Such uses are known.

[0005] The invention further relates to a sanitary fitting. Sanitary fittings are known in the prior art.

[0006] The invention is based on the objective of enabling the connection between a sanitary valve or a sanitary cartridge and the sanitary installation assembly, and of improving the overall operating characteristics of the sanitary installation assembly. This objective is achieved by the features of the independent claims. Advantageous embodiments are described in the dependent claims.

[0007] It should be noted that the features listed individually in the dependent claims can be combined with one another in any technologically meaningful way and define further embodiments of the invention, as long as these combinations include the features of at least one independent claim. Furthermore, the features specified in the claims are further detailed and explained in the description, which also presents further preferred embodiments of the invention.

[0008] To solve the stated problem, the invention proposes the features of claim 1. In particular, according to the invention, for a connecting part of the type described above, it is proposed that the contact surface is set back from a wall of the hose receptacle. In particular, the contact surface can be set back in an axial direction. The axial direction is understood to be the direction in which a flow is intended to flow out of the connecting part. In particular, the contact surface is set back from an outer boundary of a wall of the hose receptacle.

[0009] In other words, the connection part is designed such that, in an installation situation where the outlet opening of the connection part is oriented downwards, the lowest point of the hose receptacle wall is positioned lower than the contact surface. The contact surface is preferably planar, and the points of the plane forming the contact surface lie, in a side view of the connection part in the installation situation described here, above the lowest point of the hose receptacle.

[0010] In particular, the mounting surface can be designed as a sealing surface. This prevents water from escaping at a dividing line between the aerator and the connection part during operation if an aerator is arranged on the mounting surface.

[0011] The contact surface can, in particular, surround an outlet opening of the connection part. This allows an aerator to be positioned so precisely on the connection part that the flow exiting the connection part flows into the aerator – preferably without flow losses. Furthermore, this design of the contact surface ensures a particularly secure fit of the aerator against the connection part.

[0012] Advantageous embodiments of the invention are described below, which can be combined alone or in combination with the features of other embodiments, optionally together with the features according to claim 1.

[0013] In an advantageous embodiment, the connection part can have a head section and a foot section, wherein the two sections, i.e., the head section and the foot section, are angled relative to each other. Angled means that a non-zero angle is formed between the foot section and the head section. This ensures proper positioning of the connection part within the sanitary fitting. In an alternative embodiment, the head section and the foot section can be aligned straight relative to each other, rather than angled.

[0014] The head section is specifically the area where a flexible hose can be detachably or permanently connected, i.e., in particular the hose receptacle. The foot section is the area connected to the head section and where the outlet opening and the contact surface for attaching the aerator are located. Preferably, the contact surface—or, if the contact surface is designed as a sealing surface, the sealing surface—forms a boundary of the foot section in the axial direction. Thus, no element of the foot section projects beyond the contact surface or the sealing surface in the axial direction.

[0015] If the connector has a head section and the head section has a hose receptacle, the hose receptacle can be configured, in particular, along a first axis. Additionally, if the connector has a foot section and the foot section has an outlet opening and / or a contact surface, the outlet opening can be configured, in particular, orthogonal to a second axis. The contact surface, also located in the foot section, can be configured, in particular, around a third axis, wherein the contact surface is preferably formed orthogonally to the third axis. The orientation of the second axis can, in particular, coincide with the axial direction described herein. The second axis and the third axis can, in particular, be congruent. Additionally or alternatively, the first axis and the second axis and / or the first axis and the third axis can be oriented at an angle to each other.If the first axis and the second axis and / or the first axis and the third axis are aligned at an angle to each other, the head area and the foot area are angled to each other.

[0016] In practice, the head and foot sections can be angled relative to each other at an angle of at least 45°, preferably at least 90°, and at an angle of at most 180°, preferably at most 135°. In other words, the first axis and the second axis and / or the first axis and the third axis can be angled relative to each other within the aforementioned range. This allows for a particularly good compromise between good flowability and a low profile of the connection part.

[0017] Additionally or alternatively, in the axial direction in which a flow is intended to exit the connection part, the foot section, for example, the one already mentioned, can have a lower height than the head section, for example, the one already mentioned. As described, the axial direction can, in particular, coincide with the second axis. The height of the head section can, for example, be identical to the outer diameter of the hose receptacle and / or identical to the height of the hose receptacle in the axial direction. The height of the foot section can, in particular, be less than the outer diameter of the hose receptacle and / or less than the height of the hose receptacle in the axial direction.If the base is lower than the head, the connection part, or at least a base part of the connection part (which can essentially consist of the head and base), can have a particularly low profile. The connection part, and especially the base part, can then be inserted into a fitting receptacle that is particularly shallow.

[0018] To solve the stated problem, the invention alternatively proposes the features of claim 5. In particular, according to the invention, it is thus proposed that, in a connection part of the type described above, the connection part has a support surface by which it can be positively engaged with a sanitary fitting to solve the stated problem.

[0019] The support surface increases the mechanical stability of the connection part and of a sanitary installation arrangement in a sanitary fitting.

[0020] The support surface can be designed to withstand a force introduced through the contact surface. The support surface can, in particular, act at an angle of 180° or greater, especially at an angle of 180° or greater around the second axis, relative to a sanitary fitting into which the connecting part is inserted. The support surface can, for example, be an axially oriented surface of the connecting part that rests against a sanitary fitting to absorb a pressure force introduced by a screwed-in aerator.

[0021] In practice, the support surface can be formed in a support element, which is formed or can be arranged on a side of the connection part facing away from the outlet opening. In particular, the support element can be formed or arranged on a side of the base body facing away from the outlet opening, and preferably on the base area. The support element is considered a separate component of the connection part and not as belonging to the base body, even though it is possible for the support element to be formed integrally and / or of the same material as the base body.

[0022] For example, the support element can be formed on the base body by forming the base body and the support element together in a single manufacturing step, such as casting. Alternatively, the support element can be formed on the base body by creating it directly on the base body, for example, by casting or 3D printing. Furthermore, the support element can be arranged on the base body by being positively locked, force-locked, and / or material-locked. In particular, the support element can be attached to the base body by being pushed, inserted, or clipped on. Additionally or alternatively, the support element can be attached to the base body with an adhesive bond.

[0023] The support element can have essentially any geometry, as long as it is suitable for providing support for the connection part in a sanitary fitting. In particular, if the support element is attached to or formed on the base body after its manufacture, a high degree of geometric diversity of the connection part can be achieved while simultaneously keeping manufacturing costs low. This is because, for example, a base body suitable for many applications, which is produced cost-effectively with a consistent tool, can then be combined with different support elements. Thus, for different geometries of the connection part, it is sufficient to simply adapt the tool used to manufacture the support element.

[0024] In practice, the support surface can be designed as a rounded surface, an annular surface, and / or a segmented ring surface. A rounded surface, for example, is a curved, elliptical, and / or circular surface. These surfaces can also be segmented. Additionally or alternatively, the support element can have a stepped structure on a side facing away from the contact surface. A stepped structure can have multiple steps. These steps can, in particular, rise from a region of the base furthest from the head to a region of the base closest to the head. Each step surface can form part of the support surface. Due to the stepped structure, the connecting element can have a particularly large support surface while maintaining a low overall height.This allows the connecting part with the support element featuring the stepped structure to be used in particularly flat sanitary fittings. Furthermore, or alternatively, the support element can be designed, at least partially, as a pin-shaped, tubular, and / or rounded element. A pin-shaped element can, for example, be a cylinder or a hollow cylinder. A tubular element can, for example, be a hollow cylinder. A rounded element can, for example, be an element with a curved surface, such as a sphere. It is also possible for these elements to be segmented, for example, as a cylindrical segment, a hollow cylindrical segment, or a spherical segment. In particular, an end face of the support element can, and preferably should, serve as the support surface.A support surface and a support element designed as described above are advantageously suited to absorb pressure acting on the connecting element, with which the connecting element is supported against a component of a sanitary fitting, over a distributed area.

[0025] In practice, the connecting piece can be designed such that a projection of the support surface onto a plane containing the contact surface at least partially intersects the contact surface. This allows a force introduced into the connecting piece via the contact surface to be used particularly effectively for supporting the connecting piece within a sanitary fitting. Alternatively, the projection of the support surface onto a plane containing the contact surface can lie within a plane surrounded by the contact surface. This allows for a particularly good compromise between effective force transmission into the connecting piece and a compact design of the connecting piece.

[0026] In a preferred embodiment of the connecting part, a support element, such as the one described, can be detachably attached to or arranged on one or the base body of the connecting part. Such a detachable connection allows for a flexibly changeable combination of a base body and a support element, or of a set of different support elements. Preferably, the support element is detachably connected to the base of the connecting part. As described, the support element can, in particular, be attached by being pushed on, inserted, or clipped on.

[0027] To solve the aforementioned problem, the invention provides the features of the dependent claim directed to a method. In particular, according to the invention, in a method of the type described at the outset, it is proposed to solve the aforementioned problem by introducing the connection part into an interior of the fitting body through an outlet opening of the sanitary fitting.

[0028] In particular, the connecting part, with a support element formed or arranged on the base body, can be inserted through an outlet opening of the sanitary fitting into an interior of the fitting. Additionally or alternatively, the connecting part, with a hose attached to the hose receptacle, can be inserted through an outlet opening of the sanitary fitting into an interior of the fitting.

[0029] Furthermore, the connecting part can be inserted into the interior of the fitting body through an outlet opening in the fitting body. The fitting body can, for example, be an outlet pipe.

[0030] In a further process step, an aerator can be additionally or alternatively integrated into the outlet opening of the sanitary fitting. This process makes it possible to easily construct a sanitary fitting with a connection part, and in particular with the connection part described here, in which the fitting body, especially the metallic one, is formed in one piece and in which a flowing fluid does not come into contact with the fitting body.

[0031] To solve the aforementioned problem, the invention provides the features of the dependent claim relating to a sanitary installation arrangement. In particular, according to the invention, for a sanitary installation arrangement of the type described above, it is proposed that the connecting part forms the contact surface or a contact surface in the axial direction for the aerator. Thus, a connection can be provided between a sanitary valve or a sanitary cartridge and a flexible hose and the sanitary installation arrangement. As described, the axial direction is understood to be the direction of the flow.

[0032] It may be specifically designed that the installation surface is configured as a sealing surface. In this regard, reference is made to the description of the connection part, which is applicable to the sanitary installation arrangement.

[0033] To solve the stated problem, the invention alternatively proposes the features of claim 12. In particular, according to the invention, for a sanitary installation arrangement of the type described above, it is proposed that the connecting part has a base body or a base body and a reinforcing element arranged along a circumferential section of the base body. Preferably, the reinforcing element is annular, for example, slotted. This allows the connecting part to be reinforced so that no deformation of the connecting part can occur in a water flow and optimal force distribution and stiffening can be achieved.

[0034] Preferably, the reinforcing element has a higher strength than the connecting part. The reinforcing element can also be designed as a crimped sleeve. Alternatively, the reinforcing element can be designed as a cap.

[0035] The reinforcing element can have an L-shaped cross-section, i.e., in the direction of rotation, for example, by means of the previously mentioned crimping. This allows for manufacturing as a bent part, especially a deep-drawn part. Alternatively, the reinforcing element can have a rectangular or square cross-section.

[0036] In an advantageous embodiment, the reinforcing element may have a slot. A support rib can thus be formed in the slot, which increases the mechanical stability of the connecting part.

[0037] Preferably, the connecting part has a coupling for a flexible hose. The coupling is formed by an internal, preferably circumferential, projection into which the flexible hose can be inserted.

[0038] In an advantageous embodiment, the hose connection can be designed as a detachable or non-detachable fitting for a flexible hose. This ensures that the water flows only within the hose and the sanitary installation. Therefore, specifying or standardizing the sanitary fitting for drinking water quality is no longer necessary. This can increase functionality and reduce costs, as approval for drinking water quality is no longer required.

[0039] In an advantageous embodiment, the connection part may have a double-walled section. This allows an element to be inserted into this double-walled section to enhance the functionality of the connection part. Preferably, a sealant is inserted into the double-walled section.

[0040] In an advantageous embodiment, the connecting part may have a receiving chamber for a preferably non-circular sealant. Preferably, the sealant is pressed into the receiving chamber, and additionally or alternatively, the receiving chamber is formed by the double-walled section. This provides a seal that prevents water from escaping.

[0041] In an advantageous embodiment, the preferably non-circular sealant can be formed between the aerator and the connecting part. A non-circular sealant provides an improved seal compared to a typical, standard round sealant. This creates a seal that prevents water from escaping at a dividing line between the connecting part and the aerator.

[0042] In an advantageous embodiment, the receiving space can be provided with retaining projections that prevent the sealant from falling out in the axial direction. This allows the sealant to be held in the correct position and to perform its full function.

[0043] In an advantageous embodiment, the connecting part can be supported on one or more sanitary fittings at an angle greater than or equal to 180°, in particular at an angle greater than or equal to 180° around the second axis, especially via the support surface and / or the support element described herein. This allows the connecting part to be positioned correctly and to have sufficient mechanical stability.

[0044] In an advantageous embodiment, the aerator may be provided with a thread by means of which it can be screwed into a sanitary fitting. Thus, the aerator can be fastened in the sanitary fitting, in particular in the outlet opening of the fitting body.

[0045] In an advantageous embodiment, the connecting part may be provided with support ribs. Preferably, these support ribs are distributed around the circumference. The support ribs are formed, for example, between the head and foot regions of the connecting part. This increases the stiffness and mechanical stability of the connecting part.

[0046] In an advantageous embodiment, the connecting part may be provided with an anti-rotation device that prevents it from twisting against the aerator and, additionally or alternatively, against the sanitary fitting. The anti-rotation device is preferably designed as a truncated cone or a plug. Additionally or alternatively, the support element can also serve as the anti-rotation device. This simplifies installation in the sanitary fitting.

[0047] Preferably, the anti-rotation device snaps into the opposite position of the sanitary fitting or aerator, thus preventing relative rotation between the connection part and the sanitary fitting and / or aerator.

[0048] In an advantageous embodiment, the connecting part may have retaining lugs arranged circumferentially on the outside, which are suitable for locking into an internal thread of a sanitary fitting. Preferably, the retaining lugs are arranged in the base area. Preferably, the retaining lugs are arranged at an angle to the base area of ​​the connecting part, the angle being less than 45° to an axial main direction of the base area. Thus, when assembling the connecting part, the retaining lugs can be used to lock into the internal thread of the sanitary fitting, allowing temporary positioning of the connecting part in the sanitary fitting before the connection to the aerator can be established.

[0049] Preferably, the aerator has a discharge structure and additionally or alternatively a disassembly unit. The aerator may also have its own sealant, which interacts with, and in particular is in contact with, the sealant of the connecting part. The sealant of the aerator may contact the disassembly unit.

[0050] To solve the aforementioned problem, the features of the dependent claim, which is directed towards a specific use, are provided according to the invention. In particular, to solve the aforementioned problem, it is thus proposed according to the invention, in the case of use of the type described above, that the internal thread of a sanitary fitting is suitable for the fluidic connection of a connection part having a hose receptacle to an aerator. Thus, the full functionality of the sanitary fitting can be used.

[0051] To solve the aforementioned problem, the invention provides the features of the dependent claim relating to a sanitary fitting. In particular, to solve the aforementioned problem, it is thus proposed according to the invention that a sanitary fitting of the type described above has the connection part described herein.

[0052] To solve the stated problem, the invention alternatively proposes the features of claim 19. In particular, to solve the stated problem, the invention proposes, in a sanitary fitting of the type described above, that the sanitary fitting be designed with a sanitary installation arrangement having one of the features mentioned above. Preferably, an internal thread of the sanitary fitting connects the aerator and the connection part.

[0053] The invention will now be described in more detail with reference to a few exemplary embodiments, but is not limited to these few embodiments. Further variants and exemplary embodiments of the invention result from combining the features of one or more claims with each other and / or with one or more features of the exemplary embodiments and / or the previously described variants of the devices and uses of the invention.

[0055] In the following description of various objects and embodiments of the invention, elements that are functionally identical are given the same reference numerals even if they differ in design or shape.

[0056] For clarity, not all reference symbols are shown in the figures, even though the elements may well be present. However, identical reference symbols denote functionally and / or structurally identical components and functional units.

[0057] The Fig. 1, Fig. 2 and Fig. Figure 3 shows the same embodiment of the connecting part according to the invention, which is why they are described together below.

[0058] In the Fig. 1 and Fig. 2 is the connection part 3 for a sanitary installation arrangement 1 shown separately. In Fig. Figure 3 shows the connection part 3 as a component of a sanitary installation arrangement 1 in a sanitary fitting 9. The connection part 3 has a hose receptacle 4, an outlet opening 24 and a mounting surface 5 for an aerator 2, which is, for example, in Fig. 3 is shown.

[0059] The hose receptacle 4 is, in particular, cylindrical around an axis A1. The hose receptacle 4 has a wall, for example, a hollow cylinder. A flexible hose 7 can be inserted into the hose receptacle 4, and in particular into a section of the hose receptacle 4 surrounded by the wall, as shown in Fig. 2 and Fig. 3 is shown.

[0060] The contact surface 5 is designed in this case as a sealing surface 6, which in conjunction with a counter surface of an aerator, e.g. the aerator in Fig. 3, fluid-tight. The outlet opening 24 has a circular surface (not shown) that is orthogonal to a second axis A2. The contact surface 5 is an annular surface orthogonal to an axis A3. The axes A2 and A3 are congruent. In the figures, these axes A2 and A3 are shown offset from each other only for better visibility. As particularly in Fig. As can be seen in Figure 2, the contact surface 5 has a shoulder, located particularly in the center of the ring surface, which is formed, for example, in the form of a circumferential projection. If the aerator 2 is arranged on the contact surface 5 with the shoulder, or if a sealant is arranged between the contact surface 5 and the aerator 2, the compressive stresses at the shoulder are particularly high, so that a connection formed there is particularly tight.

[0061] The connection part 3 has a head section 14 and a foot section 15, the head section 14 being essentially formed by the hose receptacle 4. The foot section 15 is formed by the components of the connection part 3 that are connected to the hose receptacle 4 and on which the outlet opening 24 and the contact surface 5 are formed. The head section 14 and the foot section 15 together form a base body 22. In this base body 22, the head section 14 and the foot section 15 are angled relative to each other. In the Fig. 1, Fig. 2 and Fig. In the embodiment of the connecting part 3 shown, the head region 14 and the foot region 15 are aligned at an angle of 90° to each other, as can be seen from the orthogonally oriented axes A1 and A2 or A1 and A3.

[0062] In the axial direction in which a flow is intended to flow out of the connection part 3 and which, in the embodiment described here, is aligned parallel to the axes A2 and A3, the contact surface 5 is recessed relative to the outer surface of the wall of the hose receptacle 4. In other words, the hose receptacle 4 projects further downwards in the axial direction than the contact surface 5. Thus, the head region 14 also projects further downwards in the axial direction than the foot region 15. The connection part 3 is therefore flat and can be inserted into a similarly flat sanitary fitting, e.g., the sanitary fitting 9. Insertion of the connection part 3 into a sanitary fitting, particularly the sanitary fitting 9, can be achieved by inserting it through an outlet opening of the sanitary fitting 9 into an interior of the fitting. For example, in Fig. The sanitary fitting 9 shown in section 3 can therefore have a one-piece fitting body encompassing the interior.

[0063] The connecting part 3 also has the support surface 8, with which the connecting part 3 can be positively engaged with the sanitary fitting 9, as shown in Fig. 3 shown. In the Fig. 1, Fig. 2 and Fig. In the embodiment of the connecting part 3 shown in Figure 3, the support surface 8 is essentially ring-shaped. The support surface 8 forms the end face of a support element 25 that is essentially hollow and cylindrical. Here, the support element 25 is formed integrally with the base 15 and is made of the same material. This makes the connecting part 3 particularly stable. However, it is also possible that the support element 25 is not formed integrally with the base 15 and / or the head 14, but rather that the support element 25 is arranged on the base 15 and / or the head 14. The term "arranged" refers in particular to the attachment or formation of the support element 25 on the already manufactured head 14 and / or the already manufactured base 15.The support element 25 is therefore not considered a component of the base body 22, even though these two components are formed in one piece in the embodiment described here.

[0064] The support element 25 can have any geometric shape, as long as it is suitable for supporting the connection part 3 and, in particular, the base body 22 against a component of the sanitary fitting 9. For example, it could also be designed, at least partially, as a spherical segment, a cylinder, or a hollow cylindrical segment. In the embodiment described here, the size and position of the essentially hollow cylindrical support element 25 are selected such that a projection of the support surface 8 onto a plane containing the contact surface 5 partially intersects the contact surface 5. In particular, Fig. Figure 2 clearly shows that the contact surface 5 and the support surface 8 lie one above the other in the axial direction, i.e., along the second axis A2 and the third axis A3. Therefore, in the aforementioned projection, an outer edge of the support surface 8 and an inner edge of the contact surface 5 are congruent, so that these surfaces intersect.

[0065] In Fig. In section 3, the connection part 3 is integrated with an aerator 2 into a sanitary fitting 9. The aerator 2 has a thread 16, which it is screwed into a mating thread in the sanitary fitting 9. The connection part 3 and the aerator 2 are arranged such that the aerator 2 lies flat and close to the contact surface 5, which is designed as a sealing surface 6, and exerts a contact pressure along axis A3 on the contact surface 5. This pressure acts through the connection part 3 and, in particular, through the support element 25 on the support surface 8, which rests against a complementary mating surface of the sanitary fitting 9. The internal thread of the sanitary fitting 9 is thus used to create a fluidic connection between the connection part 3 and the aerator 2, with the connection part 3 being pressed in between the aerator 2 and the sanitary fitting 9.

[0066] The figures described below show, in particular, various embodiments of a connecting part 3 described herein. In some embodiments, certain features of the invention may not be shown. However, all features described herein are applicable to each of the illustrated variants.

[0067] The in Fig. The connection part 3 shown in section 4 bears a high resemblance to the one shown in the Fig. 1, Fig. 2 to Fig. The connection part shown in section 3 is shown. Therefore, only the differences between these two design variants are described. In particular, the difference lies in the Fig. 4 shown connection part 3 of the one in the Fig. 1, Fig. 2 to Fig. The connection part 3 shown in Figure 3 is distinguished by the fact that the angle between the head region 14 and the foot region 15 is not 90°. In particular, the first axis A1 and the second axis A2, as well as the first axis A1 and the third axis A3, are not orthogonally aligned to each other, but the first axis A1 is slightly diagonally oriented, so that an angle exists between the first axis A1 and the second axis A2, and between the first axis A1 and the third axis A3, which is shown in the Fig. 4 lies below the axis A1 and is formed by more than 90°.

[0068] Unlike the one in the Fig. 1, Fig. 2 to Fig. The embodiment of the connecting part 3 shown in section 3 is located in the [location] shown in [section]. Fig. It is not apparent from the connection part 3 shown in Figure 4 that the contact surface 5 is recessed relative to the wall of the hose receptacle 4. However, the foot area 15 is lower than the head area 14, so that the Fig. The connection part 3 shown in Figure 4 is nevertheless designed to be flat overall and can be inserted into a flat sanitary fitting. For particularly space-saving and easy insertion, the connection part 3 has a bend at the transition from the contact surface 5 to the hose receptacle 4. The connection part 3 is inserted into the sanitary fitting rotated slightly clockwise around the aforementioned bend, so that the base 15 of the connection part 3 is inserted with a slight upward rotation in the intended installation position shown. The sanitary fitting into which the connection part 3 is inserted has an interior geometrically adapted to the shape of the connection part 3.

[0069] Even those in Fig. 5 and Fig. The embodiment of the connecting part 3 shown in Figure 6 bears a strong resemblance to the one shown in the Fig. 1, Fig. 2 to Fig. 3 connection part 3 shown and in particular to the one in Fig. The connection part 3 shown in section 4 is therefore only described in terms of its differences. As with the one in Fig. In the embodiment shown and described above, the angle between the head region 14 and the foot region 15 is as shown in Figure 4. Fig. In the embodiment shown in Figure 5, the angle is not 90°. Rather, the first axis A1 and the second axis A2, or the first axis A1 and the third axis A3, are oriented at a slightly steeper angle to each other than in the embodiment shown in Figure 5. Fig. 4. Thus, an angle is formed between the first axis A1 and the second axis A2, or between the first axis A1 and the third axis A3, in the embodiment shown. Fig. 5 and Fig. The embodiment shown in Figure 6 is larger than the corresponding angle at which the angle is shown in Figure 6. Fig. 4 shown embodiment.

[0070] Even in the Fig. 5 and Fig. It is not apparent from the connection part 3 shown in Figure 6 that the contact surface 5 is recessed relative to the wall of the hose receptacle 4. However, the foot area 15 of the connection part shown in Figure 6 also shows that the contact surface 5 is recessed relative to the wall of the hose receptacle 4. Fig. 5 and Fig. The connection part shown in Figure 6 has a lower height than the head area 14 and the kink described above at the transition from the contact surface 5 to the hose receptacle 4, so that the connection part 3 is nevertheless flat overall and – as shown in Figure 6 – Fig. 5 shown - can be used in a flat sanitary fitting, especially when turned clockwise.

[0071] The support element 25 of the in Fig. 5 and Fig. The embodiment shown in Figure 6 is based on the support element located in the Fig. 1, Fig. 2 to Fig. 3 and the embodiments shown in 4 are geometrically modified. The one in Fig. 5 and Fig. The support element 25 shown in Figure 6 also has a substantially hollow cylindrical basic shape. The support element 25 additionally features a stepped structure on one side of the connecting part 3 facing away from the contact surface 5. In the case of the Fig. 5 and Fig. The connection part 3 shown in Figure 6 has three steps on the support element 25. However, there can also be more or fewer than three steps. In particular, the steps of the stepped structure can be parallel to the contact surface 5 and each form a portion of the support surface 8. The steps can have essentially the same height. Due to the stepped design, it is possible to have a particularly large support surface 8 on the support element 25, while simultaneously keeping the height of the support element 25 extremely low. This allows the connection part 3 to still be inserted into a flat sanitary fitting. The steps can also be used as a rotation lock, particularly against torque applied to the contact surface 5 and / or the sealing surface 6.

[0072] The stepped structure of the support element 25 is not generally limited to support elements with an essentially hollow cylindrical base shape, but can also be advantageously designed in other types of support elements. Furthermore, it is not necessary for the stepped structure to be parallel to the contact surface 5. Alternatively, the steps can be inclined, for example, to form a structure similar to a sawtooth profile.

[0073] The in Fig. The sanitary fitting shown in Figure 5, into which the connection part 3 is inserted, has an interior geometrically adapted to the shape of the connection part 3. The sanitary fitting is designed to be particularly flat.

[0074] Even those in Fig. The embodiment of the connecting part 3 shown in Figure 7 bears a strong resemblance to the one shown in the Fig. 1, Fig. 2 to Fig. The connection part shown in section 3 is therefore only described in terms of its differences. Fig. In the embodiment shown in Figure 7, the foot section 15 is essentially shaped like a truncated hollow cone. Above the truncated hollow cone-shaped foot section 15, the support element 25 is designed in the form of a spherical segment with the support surface 8. A [missing text] in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 to Fig. The essentially hollow cylindrical support element shown in Figure 6 exhibits the following features: Fig. The embodiment of the connecting part 3 shown in Figure 7 is not included, although this is in addition to or as an alternative to the embodiment described here and in Figure 7. Fig. The support element shown in 7 can be formed as 25.

[0075] The Fig. Figure 8 shows another embodiment of a connecting part 3 described herein. In the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. In the embodiments of a connecting part 3 shown in Figure 7, the support element 25 is formed in one piece and, in particular, of the same material as, or formed on, the base body 22. As described, this results in particularly high mechanical stability of the connecting part 3. In the embodiment shown in Fig. In the embodiment of a connecting part 3 shown in Figure 8, the support element 25 is not formed integrally with or on the base body 22, but the support element 25 is formed as a separate component and attached to the already manufactured base body 22.

[0076] In particular, the in Fig. The support element 25 shown in Figure 8 has a pin-shaped form, wherein at least on the side of the support element 25 facing away from the base body 22, a spherical segment in the form of a hemisphere is formed. The surface of the hemisphere is the support surface 8. The support element 25 is inserted into the foot region 15 of the connecting part 3 in a counterpart form, which here, for example, is designed to be complementary. Alternatively or additionally, the support element 25 can be connected to the base body 22 and, in particular, to the foot region 15 by means of an adhesive bond and / or by means of a clip connection. The Fig. The support element 25 shown in Figure 8 is oriented with respect to the base area 15 and the contact surface 5 such that a force introduced into the contact surface 5 along the axial direction acts along the longitudinal axis of the support element 25. For this purpose, a projection of the support surface 8 onto a plane containing the contact surface 5 lies in a surface surrounded by the annular contact surface 5. To improve force transmission, the connecting part 3 has support ribs 17, by means of which the force exerted on the contact surface 5 is transmitted particularly well to the support element 25; however, these ribs are not essential for the connecting part 3.

[0077] Fig. Figure 9 shows a sanitary installation arrangement 1 according to the invention, which is installed in a sanitary fitting 9.

[0078] The sanitary installation assembly 1 comprises an aerator 2 and a connection part 3. The connection part 3 is positioned upstream of the aerator 2 in the direction of flow. The aerator 2 has a thread 16, which is screwed into an internal thread 20 of the sanitary fitting 9. The connection part 3 has a hose receptacle 4 into which a flexible hose 7 is inserted. The connection part has a contact surface 5, which is designed axially for the aerator 2. The contact surface 5 is designed as a sealing surface 6. The connection part 3 has a support surface 8, which allows it to be positively engaged with the sanitary fitting 9. The connection part 3 has a head section 14 and a foot section 15, which are angled relative to each other. The head section 14 is the area in which the hose receptacle 4 is formed. The foot section 15 is the area against which the aerator 2 rests.The connection part 3 has support ribs 17 distributed around its circumference. These support ribs 17 are located between the head section 14 and the foot section 15 and provide rigidity to the connection part 3. The connection part 3 also has an anti-rotation device 18, which prevents it from rotating relative to the sanitary fitting 9. The connection part 3 has retaining lugs 19 arranged around its outer circumference, which are designed to engage with the internal thread 20 of the sanitary fitting 9. These retaining lugs 19 are necessary during the installation of the sanitary fitting 1 to hold the connection part 3 in position while a connection is made with the aerator 2.

[0079] Fig. Figure 10 shows the sanitary installation arrangement 1 from Fig. Figure 9 shows the sanitary fitting 9 in a top view as installed. The connection part 3 is visible, as are the head section 14 and the foot section 15. The anti-rotation device 18 is also visible as a round element. Here, the anti-rotation device 18 is designed as a truncated cone. Alternatively, the anti-rotation device 18 can be designed as a plug.

[0080] Fig. Figure 11 shows a connection part 3 in a perspective side view. The head section 14 and the foot section 15 are formed at an angle of equal to or approximately 90°. Retaining lugs 19 are arranged laterally around the foot section 15. The hose receptacle 4 is also visible. Inside the connection part 3, the hose receptacle 4 has an internal, circumferential projection that can accommodate a flexible hose 7. Support ribs 17 are formed between the head section 14 and the foot section 15 and stiffen the structure so that no deformation occurs when water flows through it. The support surface 8 is formed between the connection part 3 and the sanitary fitting 9 (not shown here). The contact surface 5, which in this specific example is designed as a sealing surface 6, is formed on the lower part of the connection part 3.The retaining lugs 19 are arranged at an angle to the base 15 of the connecting part 3, the angle being less than 45° to an axial main direction of the base 15. The anti-rotation device 18 is formed on a cylindrical part of the head 14 and prevents the connecting part 3 from rotating relative to the sanitary fitting 9 (not shown here).

[0081] Fig. Figure 12 shows another connection part 3 in a bottom view. The connection part 3 has a receiving chamber 11 into which a non-circular sealant 12 is injected. The receiving chamber 11 has a double-walled section 10. Retaining projections 13 are formed on the receiving chamber 11 to prevent the sealant 12 from falling out axially. Retaining lugs 19 are formed in the base 15, which are necessary for mounting the sanitary installation assembly 1. The support ribs 17 stiffen the connection part 3 and are formed between the head 14 and the base 15. The head 14 and the base 15 are arranged at an angle to each other. This angle is necessary due to the design of the sanitary fitting 9 (not shown here). The sealant 12 provides a seal between the space in which water flows and another space in which water must not flow.The sanitary installation assembly 1 is designed to prevent water flow outside of it. This is necessary to avoid requiring the sanitary fitting 9 to be approved for drinking water use. This saves costs while maintaining full functionality. The hose receptacle 4 is also visible, featuring a circumferential projection into which the flexible hose 7 (not shown) can be inserted. The contact surface 5, which in this specific example is designed as a sealing surface 6, is also visible. The sealant 12 is non-circular and located in the receiving space 11. A non-circular sealant is particularly advantageous for sealing.

[0082] Fig. Figure 13 shows the connection part 4. Fig. 12 in a perspective view from below. The elements were already present during the Fig. The retaining lugs 19, described in section 12, are clearly visible and are formed at an angle to the base area 15. This angle is less than 45°. It was discovered during the design of the present invention that such an angle is particularly advantageous for assembly and ensures that the connecting part 3 can be crimped into the internal thread 20 of the sanitary fitting 9 (not shown here).

[0083] Fig. Figure 14 shows the connection part 3. Fig. 12 and Fig. Figure 13 shows a cross-sectional view through a middle plane. The anti-rotation device 18, located at the head 14, is visible. The non-circular sealant 12, located in the receiving chamber 11, is also visible. The receiving chamber 11 has a double-walled section 10. The head 14 and the foot 15 are angled relative to each other at approximately 45°. The support ribs 17 are formed between the head 14 and the foot 15.

[0084] Fig. Figure 15 shows a further connecting part 3 in a top view. A reinforcing element 21 is visible, which is circumferential and located on an outer area of ​​the foot section 15. The head section 14 and the foot section 15 are angled relative to each other. A single supporting rib 17 is formed between the head section 14 and the foot section 15 ( Fig. 16). Additionally, retaining lugs 19 are visible, which are arranged at an angle to the main axial axis of the base area 15. The hose receptacle 4 is also formed in the head area 14. The support surface 8 is visible, which is formed between the sanitary fitting 9 (not shown here) and the head area 14 ( Fig. 16) In this specific case, the support surface 8 is formed directly on the reinforcing element 21. The reinforcing element 21 is designed here as a steel disc. Alternatively, materials other than metals are possible for the reinforcing element 21, as long as they have a higher strength than the connecting part 3. The steel disc serves to stiffen the connecting part 3 so that no deformation can occur in a water flow. The basic body 22 is considered here to be the combined head region 14 and foot region 15.

[0085] The reinforcing element 21 is slotted through a slot 23 in which the support rib 17 can be arranged.

[0086] Fig. Figure 17 shows the connection part 3. Fig. 15 and Fig. Figure 16 shows a cross-sectional view through a central plane. No anti-rotation device 18 is shown. Inside the head section 14, a projection is formed on which a flexible hose 7 is located or rests during operation. The head section 14 and the foot section 15 are angled relative to each other, the angle depending on the structure of the sanitary fitting 9 (not shown here). The reinforcing element 21, which is designed here as a steel disc, rests against an outer side of the connection part 3. No sealant is applied to the contact surface 5. Alternatively, the reinforcing element 21 can also be made of materials other than metal that have a higher strength than the connection part 3 or the base body 22. The reinforcing element 21 can have an L-shaped cross-section, i.e., in the direction of rotation. This allows it to be manufactured as a bent part, in particular a deep-drawn part.Alternatively, the reinforcing element 21 can have a rectangular cross-section. The reinforcing element 21 can also be designed as a crimped sleeve or a cap, as an alternative to the metal ring.

[0087] Fig. Figure 18 shows another connection part 3 in a bottom view. Connection part 3 has the elements already described above, which are not explained separately here. The contact surface 5 is designed here as a sealing surface 6. The hose receptacle 4 and the internal, circumferential projection are visible.

[0088] Fig. Figure 19 shows the connection part 3. Fig. Figure 18 shows a perspective view from below. The support ribs 17 are visible, located between the head region 14 and the foot region 15. The sealant 12 is non-circular, in particular T-shaped (see Figure 18). Fig. 20).

[0089] Fig. 20 shows the connection part 3 from Fig. 18 and Fig. Figure 19 shows a cross-sectional view through a middle plane. The sealant 12 is located in the receiving chamber 11, which has a double-walled section 10. The anti-rotation device 18 is also visible. The angled retaining lugs 19 are also visible.

[0090] Fig. Figure 21 shows a further connection part 3 in a side view. The head section 14 and the foot section 15 are angled relative to each other. Support ribs 17 are arranged between the two parts 14 and 15, increasing the rigidity of the structure. The anti-rotation device 18 is visible. In the lower area, against which the aerator 2 (not shown) rests in a sanitary installation 1 (not shown here), is the contact surface 5, which is designed as a sealing surface 6. The retaining lugs 19, which circumferentially surround the outside of the foot section 15 and are angled, are also visible.

[0091] Fig. 22 shows the connection part 3 from Fig. 21 in a perspective view from above. The existing elements have already been described above and will not be explained again separately.

[0092] Fig. Figure 23 shows another connection part 3 in a side view. The difference between this connection part 3 and the connection parts 3 described above is that the head section 14 and the foot section 15 run in a straight line, and are not angled relative to each other. The connection part 3 has no support ribs 17, i.e., it is designed without support ribs. The connection part 3 has angled retaining lugs 19. In the lower area, the contact surface 5, which is designed as a sealing surface 6, is visible. A sealant 12 is also visible. The outer area of ​​the head section 14 is designed as a support surface 8, against which the sanitary fitting 9 (not shown here) is supported. The connection part 3 does not have an anti-rotation device 18.

[0093] Fig. Figure 24 shows the connection part 3. Fig. 23 in a perspective view from above. The connecting part 3 is designed without support ribs. The connecting part 3 has no anti-rotation device 18. The head region 14 and the foot region 15 are not angled, but rather formed along a straight line. Angled retaining lugs 19 are visible on the connecting part 3.

[0094] It is proposed that a sanitary installation arrangement 1 comprises a jet regulator 2 and a connection part 3, wherein the connection part 3 is positioned upstream of the jet regulator 2 in the direction of flow, and wherein the connection part 3 has a hose receptacle 4 and wherein the connection part 3 forms a contact surface 5 in the axial direction for the jet regulator 2.
