Description

[0001] Connection part, method for inserting a connection part, sanitary installation arrangement, use of an internal thread and sanitary fitting

[0002] The invention relates to a connecting part for a sanitary installation, wherein the connecting part has a hose receptacle, an outflow opening, and a contact surface for a jet regulator. The contact surface can be designed, in particular, as a sealing surface. Furthermore, in particular, the contact surface can surround the outflow opening of the connecting part. Such a connecting part is known in practice.

[0003] The invention further relates to a method for inserting a connecting part, in particular the connecting part described here, into a sanitary fitting. Methods for inserting a connecting part into a sanitary fitting are also known in practice.

[0004] The invention also relates to a sanitary installation arrangement comprising a jet regulator and a connecting part which is arranged upstream of the jet regulator in the direction of flow, wherein the connecting part has a hose receptacle. Such a sanitary installation arrangement is known in practice.

[0005] The invention further relates to the use of an internal thread. Such uses are known.

[0006] The invention further relates to a sanitary fitting. Sanitary fittings are known in the prior art.

[0007] The invention is based on the object of enabling the connection between a sanitary valve or a sanitary cartridge and the sanitary installation arrangement and of overall improving the operating characteristics of the sanitary installation arrangement. This object is achieved by the features of the independent claims. Advantageous embodiments are described in the subclaims.

[0008] It should be noted that the features listed individually in the dependent claims can be combined with one another in any technologically expedient manner and define further embodiments of the invention, as long as these combinations comprise the features of at least one independent claim. Furthermore, the features listed in the claims are further specified and explained in the description, with further preferred embodiments of the invention being presented.

[0009] To achieve the stated object, the invention proposes the features of claim 1. In particular, in the case of a connecting part of the type described at the outset, the invention proposes that the contact surface is set back relative to 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 a direction in which a flow flows out of the connecting part as intended. In particular, the contact surface is set back relative to an outer boundary of a wall of the hose receptacle.

[0010] In other words, the connecting part is designed such that, in an installation situation of the connecting part in which the outflow opening of the connecting part is oriented in a downward direction, the lowest point of the wall of the hose receptacle is arranged further down than the contact surface. The contact surface is designed in particular in a preferably planar plane and the points of the plane which form the contact surface lie above the lowest point of the hose receptacle in a side view of the connecting part in the installation situation described here.

[0011] In particular, it can be provided that the contact surface is designed as a sealing surface. This can prevent water from escaping at a dividing line between the jet regulator and the connecting part during operation, particularly when a jet regulator is arranged on the contact surface.

[0012] The contact surface can, in particular, surround an outflow opening of the connecting part. Thus, a jet regulator can be arranged on the connecting part in such a way that a flow flowing out of the connecting part flows into the jet regulator—preferably without flow losses. Furthermore, with this design of the contact surface, the jet regulator can rest particularly securely against the connecting part.

[0013] Advantageous embodiments of the invention are described below, which can optionally be combined with the features of claim 1 alone or in combination with the features of other embodiments.

[0014] In an advantageous embodiment, the connecting part can have a head region and a foot region, wherein the two regions, i.e. the head region and the foot region, are angled towards one another. Angled means that an angle other than zero is formed between the foot region and the head region. In this way, positioning of the connecting part in the sanitary fitting can be guaranteed. In an alternative embodiment, it can be provided that the head region and the foot region are not angled towards one another, in particular are straight. The head region is in particular the region to which a flexible hose can be connected detachably or non-detachably, i.e. in particular the hose receptacle. The foot region is the region which is connected to the head region and on which the outflow opening and the contact surface for applying the jet regulator are formed. The contact surface or...If the contact surface is designed as a sealing surface, the sealing surface forms a boundary of the base area in the axial direction. Thus, no element of the base area protrudes beyond the contact surface or the sealing surface in the axial direction.

[0015] If the connecting part has the head region and the head region has the hose receptacle, the hose receptacle can in particular be formed along a first axis. In addition, if the connecting part has the foot region and the foot region has the outflow opening and / or the contact surface, the outflow opening can in particular be formed orthogonally to a second axis. The contact surface, which is also arranged in the foot region, can in particular be formed 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 correspond to the axial direction described here. 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 aligned at an angle to one another.When 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 region and the foot region can be aligned at an angle of at least 45°, preferably at least 90°, and at an angle of at most 180°, preferably at most 135°, relative to one another. In other words, the first axis and the second axis and / or the first axis and the third axis can be aligned at an angle within the aforementioned range relative to one another. This allows a particularly good compromise to be achieved between good flowability and a low overall height of the connecting part.

[0017] Additionally or alternatively, in the axial direction in which a flow flows out of the connecting part as intended, a foot region, for example the one already mentioned, can have a lower height than a head region, for example the one already mentioned. As described, the axial direction can in particular be congruent with the second axis. The height of the head region can for example be identical to the outer diameter of the hose receptacle and / or identical to a height of the hose receptacle in the axial direction. The height of the foot region 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 foot area is lower than the head area, the connecting part or at least a base body of the connecting part, which can essentially consist of the head area and the foot area, can have a particularly low overall height. The connecting part and in particular the base body can then be inserted into a receptacle of a sanitary fitting that is particularly flat.

[0018] To achieve the stated object, the invention alternatively proposes the features of claim 5. In particular, in the case of a connecting part of the type described above, the invention proposes to achieve the stated object by providing the connecting part with a support surface by means of which the connecting part can be applied to a sanitary fitting in a form-fitting manner.

[0019] Due to the support surface, the mechanical stability of the connecting part and of a sanitary installation arrangement in a sanitary fitting comprising the connecting part can be increased.

[0020] The support surface can be designed to support a force that can be introduced through the contact surface. The support surface can act, in particular, at an angle equal to or greater than 180°, in particular at an angle equal to or greater than 180° 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 aligned surface of the connecting part that bears against a sanitary fitting in order to absorb a compressive force that is introduced by a screwed-in jet regulator.

[0021] In practice, the support surface can be formed in a support element, wherein the support element is formed or can be arranged on a side of the connecting part facing away from the outflow opening. In particular, the support element can be formed or can be arranged on a side of the base body facing away from the outflow opening and preferably on the foot region. The support element is considered a separate component of the connecting part and not as belonging to the base body, even if it is possible for the support element to be formed in one piece and / or from 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 common manufacturing step, for example, by casting them. Alternatively, the

[0023] The support element can be formed on the base body by producing the support element on the base body, for example by casting or 3D printing. Furthermore, for example, the support element can be arranged on the base body by connecting the support element to the base body in a form-fitting, force-fitting and / or material-fitting manner. In particular, the support element can be plugged, inserted or clipped onto the base body. Additionally or alternatively, the support element can be fastened to the base body with an adhesive connection.

[0024] The support element can have essentially any geometry, as long as it is suitable for providing a supporting effect for the connecting part in a sanitary fitting. In particular, if the support element is arranged or formed on the base body after the base body has been manufactured, a high degree of geometric variety for the connecting part can be achieved while at the same time keeping manufacturing costs low. This is because then, for example, a base body which is suitable for many applications and is manufactured cost-effectively using the same tool can be combined with different support elements. It is therefore sufficient to simply adapt the tool used to manufacture the support element for different geometries of the connecting part.

[0025] In practice, the support surface can be designed in particular as a rounded surface, an annular surface and / or a ring segment surface. A rounded surface is, for example, a curved surface, an elliptical and / or a circular surface. It is also possible for these surfaces to be pieced together. 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 a plurality of steps. The steps can in particular rise from a region of the foot region remote from the head region to a region of the foot region close to the head region. In particular, each of the stepped surfaces of the steps can form a component of the support surface. Due to the stepped structure, the connecting part can have a particularly large support surface while the support element still has a low height.As a result, the connecting part with the support element having the step-shaped structure can be used in particularly flat sanitary fittings. Furthermore, or alternatively, the support element can be designed at least partially as a pin-shaped, a tubular and / or a rounded element. A pin-shaped element can be, for example, a cylinder or a hollow cylinder. A tubular element can be, for example, a hollow cylinder. A rounded element can be, for example, an element with a curved surface, such as a sphere. It is also possible for these elements to be pieced together, for example as a cylinder segment, as a hollow cylinder segment or as a sphere segment. In particular, an end face of the support element can have the support surface and can preferably be the support surface.A support surface designed as described above and a support element designed as described above are advantageously suitable for absorbing a pressure acting on the connecting element, with which the connecting element is supported against a component of a sanitary fitting, over a distributed area.

[0026] In practice, the connecting part 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. In this way, a force introduced into the connecting part through the contact surface can be used particularly effectively to support the connecting part in a sanitary fitting. Alternatively, a projection of the support surface onto a plane containing the contact surface can lie in an area surrounded by the contact surface. In this way, a particularly good compromise can be achieved between effective introduction of the force into the connecting part and a small overall size of the connecting part.

[0027] In a preferred embodiment of the connecting part, a support element, for example the one described, can be detachably arranged on or attached to a base body of the connecting part. Such a detachable connection allows a flexibly changeable combination of a base body and a support element from a plurality of different support elements. The support element is preferably detachably connected to the base region of the connecting part. As described, the support element can in particular be plugged on, inserted, or clipped on.

[0028] Additionally or alternatively, the connecting part may be provided with a means for establishing a positive and / or non-positive connection of the connecting part to a sanitary fitting. For details on the means for establishing a positive and / or non-positive connection, reference is also made to the description of the method for inserting the connecting part and the description of the sanitary fitting.

[0029] To achieve the stated object, the invention provides the features of the independent claim directed to a method. In particular, in a method of the type described at the outset, the invention proposes that the connecting part is introduced through an outlet opening of the sanitary fitting into an interior space of the sanitary fitting. In particular, the connecting part can be introduced with a support element formed or arranged on the base body through an outlet opening of the sanitary fitting into an interior space of the sanitary fitting. Additionally or alternatively, the connecting part can be introduced with a hose arranged on the hose receptacle through an outlet opening of the sanitary fitting into an interior space of the sanitary fitting.

[0030] Furthermore, the connecting part can be introduced into the interior of the fitting body through an outlet opening in the fitting body of the sanitary fitting. The fitting body can, for example, be an outlet pipe.

[0031] In practice, the connecting part can be fixed in the interior of the sanitary fitting with a positive and / or force fit. This allows the connecting part to be easily positioned and held in the sanitary fitting during the procedure, without the person performing the procedure having to hold it manually.

[0032] In particular, one or the mentioned means for producing the positive and / or non-positive connection of the connecting part can interact with a counter-measure of the sanitary fitting in order to hold the connecting part in the sanitary fitting. The counter-measure can preferably be designed and arranged in such a way that it can act on a side of the connecting part facing away from the outflow opening. For example, the counter-measure can be formed on a side opposite the outlet opening in the interior of the sanitary fitting. The means for producing the positive and / or non-positive connection can accordingly be formed on a side of the connecting part facing away from the outflow opening, for example on a support element and in particular the support element described here.Due to the described positioning of the means for establishing the positive and / or non-positive connection and the countermeasure, the connection between the connecting part and the sanitary fitting is not visible and / or accessible from the outside after the connecting part has been inserted.

[0033] In particular, the countermeasure can be a ring protruding from a wall of the sanitary fitting into the interior. The means for producing the positive and / or non-positive connection can be a flat surface of the support element, in particular a casing surface. Alternatively or additionally, the means for producing the positive and / or non-positive connection can be a locking lug protruding outwards from a surface of the connecting part or a ring protruding therefrom. The described flat surface can be partially enclosed in the circumferential direction by the ring protruding from the wall of the sanitary fitting and clamped in the process, making it particularly easy to insert. A locking lug protruding outwards or a ring protruding outwards can engage behind the ring protruding into the interior, thus creating a particularly strong connection.

[0034] In a further method step, it can additionally or alternatively be provided that a jet regulator is introduced into the outlet opening of the sanitary fitting. The method makes it possible to form a sanitary fitting with a connecting part and in particular with the connecting part described here in a simple manner, in which the fitting body, in particular a metal one, is formed in one piece and in which a flowing fluid does not come into contact with the fitting body. To achieve the stated object, the features of the independent claim directed to a sanitary installation arrangement are provided according to the invention. In particular, in the case of a sanitary installation arrangement of the type described at the outset, to achieve the stated object, it is proposed according to the invention that the connecting part forms the contact surface or a contact surface in the axial direction for the jet regulator.Thus, a connection can be provided between a sanitary valve or a sanitary cartridge and a flexible hose and the sanitary installation assembly. The axial direction, as described, is understood to be the direction of flow.

[0035] In particular, it can be provided that the contact surface is designed as a sealing surface. In this regard, reference is made to the description of the connecting part, which is applicable to the sanitary installation arrangement.

[0036] To achieve the stated object, the invention alternatively proposes the features of claim 13. In particular, in a sanitary installation arrangement of the type described above, the invention proposes to achieve the stated object by providing that the connecting part has the base body or a base body and a reinforcing element arranged along a circumferential section of the base body. The reinforcing element is preferably annular, for example slotted. This allows the connecting part to be strengthened so that no deformation of the connecting part can occur in a water flow and optimal force distribution and stiffening can take place.

[0037] Further advantageous embodiments of the invention are described below, which alone or in combination with the features of other embodiments can optionally be combined with the features of the subject matter of the independent claims.

[0038] Preferably, the reinforcing element has greater strength than the connecting part. The reinforcing element can also be designed as a flanged sleeve. Alternatively, the reinforcing element can be designed as a cap.

[0039] The reinforcing element can be L-shaped in cross-section, i.e., in the circumferential direction, for example, through the aforementioned flanging. This enables production as a bent part, particularly a deep-drawn part. Alternatively, the reinforcing element can be rectangular or square in cross-section.

[0040] In an advantageous embodiment, the reinforcing element can be provided with a slot. Thus, a support rib can be formed in the slot, which increases the mechanical stability of the connecting part.

[0041] The connecting part preferably 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.

[0042] In an advantageous embodiment, it can be provided that the hose receptacle is designed for a detachable or permanent connection of a flexible hose. This ensures that the water only flows within the hose and the sanitary installation arrangement. A specification or standardization of the sanitary fitting for drinking water quality is therefore no longer necessary. This can increase functionality and reduce costs, since approval for drinking water quality is no longer necessary. In an advantageous embodiment, it can be provided that the connecting part has a double-walled section. This means that an element can be inserted into this double-walled section in order to increase the functionality of the connecting part. A sealing agent is preferably inserted into the double-walled section.

[0043] In an advantageous embodiment, the connecting part can be provided with a receiving space for a preferably non-circular sealing means. Preferably, the sealing means is pressed into the receiving space, and additionally or alternatively, the receiving space is formed by the double-walled section. Thus, a seal can be provided that prevents water from escaping.

[0044] In an advantageous embodiment, the preferably non-circular sealing means can be formed between the jet regulator and the connecting part. A non-circular sealing means provides a better seal than a typical, standard round sealing means. Thus, a seal can be provided that prevents water from escaping at a dividing line between the connecting part and the jet regulator.

[0045] 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 perform its full functionality.

[0046] In an advantageous embodiment, it can be provided that the connecting part is supported on a sanitary fitting at an angle greater than or equal to 180°, in particular at an angle greater than or equal to 180° around the second axis, in particular via the support surface and / or the support element described here. Thus, the connecting part can be well positioned and has sufficient mechanical stability.

[0047] In an advantageous embodiment, the jet regulator can be provided with a thread by means of which it can be screwed into a sanitary fitting. Thus, the jet regulator can be fastened in the sanitary fitting, in particular in an outlet opening in the fitting body of the sanitary fitting.

[0048] In an advantageous embodiment, the connecting part can be provided with support ribs. These support ribs are preferably distributed around the circumference. The support ribs are formed, for example, between the head region and the foot region of the connecting part. This can increase the rigidity and mechanical stability of the connecting part.

[0049] In an advantageous embodiment, the connecting part can be provided with an anti-twist device, which prevents the connecting part from twisting against the aerator and additionally or alternatively against the or a sanitary fitting. The anti-twist device is preferably designed as a truncated cone or stopper. Additionally or alternatively, the support element can be the anti-twist device. This can simplify installation in the sanitary fitting.

[0050] Preferably, the anti-twist device snaps into a part opposite the sanitary fitting or the jet regulator and thus prevents a relative twisting between the connecting part and the sanitary fitting and / or the jet regulator. In an advantageous embodiment, it can be provided that the connecting part has retaining lugs arranged on the outside on the circumference, which can be locked with a

[0051] Internal thread of one or more sanitary fittings are suitable. The retaining lugs are preferably arranged in the base region. The retaining lugs are preferably arranged at an angle to the base region of the connecting part, wherein the angle is less than 45° to a main axial direction of the base region. Thus, when assembling the connecting part, the retaining lugs can be used to lock into the internal thread of the sanitary fitting, so that temporary positioning of the connecting part in the sanitary fitting is possible and the connection to the jet regulator can then be created.

[0052] In an advantageous embodiment, it can be provided that the connecting part has resilient spring tongues arranged on the outside around the circumference. The spring tongues can carry the retaining lugs. The resilient spring tongues are preferably suitable for locking with an internal thread of a or the sanitary fitting. The spring tongues are preferably arranged in the base region. The spring tongues are preferably arranged at an angle to the base region of the connecting part, wherein the angle is less than 60° to a main axial direction of the base region, which can in particular be oriented along the described second axis. The spring tongues can therefore be used when assembling the connecting part to lock into the internal thread of the sanitary fitting, so that a temporary positioning of the connecting part in the sanitary fitting is possible and the connection to the jet regulator can then be created.The spring tongues serve to simplify the assembly of the connecting part and thus the jet regulator in the sanitary fitting.

[0053] In an advantageous embodiment, it can be provided that the connecting part has a tool attachment into which a suitably contoured removal tool can be inserted. The tool attachment is preferably fluid-conducting. This means that it is not necessary to reserve a separate installation space for the tool attachment. The tool attachment is preferably designed as a hexagon socket or square socket. Advantageously, the tool attachment is suitable for levering out the connecting part with the aid of the removal tool. The removal tool can be an Allen key or the like. This means that the connecting part can be easily and efficiently unscrewed from its position in the sanitary fitting. The term “fluid-conducting” means that the tool attachment has a through-opening in its interior through which water or fluids can be conducted.The tool attachment can be standardized in its shape and can be operated using standard removal tools such as Allen keys.

[0054] The jet regulator preferably has an outlet structure and, additionally or alternatively, a splitter unit. The jet regulator can also have its own sealant, which interacts with the sealant of the connecting part, in particular is in contact. The sealant of the jet regulator can contact the splitter unit.

[0055] To achieve the stated object, the features of the independent claim directed to a use are provided according to the invention. In particular, to achieve the stated object, it is therefore proposed according to the invention for a use of the type described at the outset that the internal thread of a sanitary fitting is suitable for the fluidic connection of a connecting part having a hose receptacle to a jet regulator. The full functionality of the sanitary fitting can therefore be used. To achieve the stated object, the features of the independent claim directed to a sanitary fitting are provided according to the invention. In particular, to achieve the stated object, it is therefore proposed according to the invention for a sanitary fitting of the type described at the outset that the sanitary fitting has the connecting part described here.

[0056] To achieve the stated object, the invention alternatively proposes the features of claim 21. In particular, to achieve the stated object, the invention proposes that in a sanitary fitting of the type described at the outset, the sanitary fitting is designed with a sanitary installation arrangement having one of the above-mentioned features. An internal thread of the sanitary fitting preferably connects the jet regulator and the connecting part. Additionally or alternatively, the connecting part can have a means, in particular the described means, for producing a non-positive and / or positive connection, and the sanitary fitting can have a means, in particular the described means cooperating therewith. In this way, a connection can be formed between the connecting part and the sanitary fitting which enables simple insertion of the connecting part.For further details and advantages related thereto, reference is made to the remaining description of the remedy and antidote.

[0057] The invention will now be described in more detail with reference to a few exemplary embodiments, but is not limited to these few exemplary embodiments. Further variants of the invention and exemplary embodiments arise from combining the features of individual or multiple claims with one another and / or with individual or multiple features of the exemplary embodiments and / or the previously described variants of devices and uses according to the invention.

[0094] In the following description of various objects and embodiments of the invention, elements which correspond in their function are given the same reference numerals even if they have a different design or shape.

[0095] For a better overview, not all

[0096] Reference symbols are used, even though the elements may very well be present in the figures. However, identical reference symbols designate functionally and / or structurally identical components and functional units.

[0097] Fig. 1, Fig. 2 and Fig. 3 show the same

[0098] Embodiment of the connecting part according to the invention, which is why they are described together below.

[0099] In Figs. 1 and 2, the connecting part 3 for a sanitary installation arrangement 1 is shown separately. In Fig. 3, the connecting part 3 is shown as a component of a sanitary installation arrangement 1 in a sanitary fitting 9. The connecting part 3 has a hose receptacle 4, an outflow opening 24, and a contact surface 5 for a jet regulator 2, which is shown, for example, in Fig. 3.

[0100] The hose receptacle 4 is, in particular, cylindrically shaped around an axis A1. The hose receptacle 4 has a wall formed, for example, as 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.

[0101] The contact surface 5 is designed here as a sealing surface 6 which interacts in a fluid-tight manner with a mating surface of a jet regulator, for example the jet regulator in Fig. 3. The outflow opening 24 has a round circular surface (not shown) which is designed orthogonal to a second axis A2. The contact surface 5 is designed as an annular surface orthogonal to an axis A3. The axes A2 and A3 are arranged congruently. In the figures, these axes A2 and A3 are shown spaced from one another only for better visibility. As can be seen in particular in Fig. 2, the contact surface 5 has a shoulder which is arranged in particular in the center of the annular surface and which is designed, for example, in the form of a circumferential projection.If the jet regulator 2 is arranged on the contact surface 5 with the shoulder, or if a sealing means is arranged between the contact surface 5 and the jet regulator 2, the compressive stresses on the shoulder are particularly high, so that a connection formed there is particularly tight.

[0102] The connecting part 3 has a head region 14 and a foot region 15, the head region 14 being essentially formed by the hose receptacle 4. The foot region 15 is formed by the components of the connecting part 3 which are connected to the hose receptacle 4 and on which the outflow opening 24 and the contact surface 5 are formed. The head region 14 and the foot region 15 together form a base body 22. In this base body 22, the head region 14 and the foot region 15 are angled relative to one another. In the embodiment of the connecting part 3 shown in Fig. 1, Fig. 2 and Fig. 3, the head region 14 and the foot region 15 are aligned at an angle of 90° to one another, as can be seen from the axes A1 and A2 or A1 and A3 which are oriented orthogonally to one another.

[0103] In an axial direction, in which a flow is intended to flow out of the connecting part 3 and which in the embodiment described here is aligned parallel to the axes A2 and A3, the contact surface 5 is set back in relation 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 connecting part 3 is therefore flat and can be inserted into a likewise flat sanitary fitting, for example the sanitary fitting 9. The connecting part 3 can be inserted into a sanitary fitting, in particular into the sanitary fitting 9, by the connecting part 3 being inserted through an outlet opening of the sanitary fitting 9 into an interior space of the sanitary fitting.The sanitary fitting 9 shown for example in Fig. 3 can thus have a one-piece fitting body enclosing the interior.

[0104] The connecting part 3 furthermore has the support surface 8, with which the connecting part 3 can be placed in a form-fitting manner on the sanitary fitting 9, as shown in Fig. 3. In the embodiment of the connecting part 3 shown in Fig. 1, Fig. 2 and Fig. 3, the support surface 8 is essentially annular. The support surface 8 forms the end face of an essentially hollow, cylindrical support element 25. The support element 25 is here formed in one piece and of the same material as the base region 15. This makes the connecting part 3 particularly stable. However, it is also possible for the support element 25 not to be formed in one piece with the base region 15 and / or with the head region 14, but for the support element 25 to be arranged on the base region 15 and / or on the head region 14.The term "arranged" refers in particular to the attachment or formation of the support element 25 to the already manufactured head region 14 and / or the already manufactured foot region 15. The support element 25 is therefore not considered to be a component of the base body 22, even if these two components are formed in one piece in the embodiment described here.

[0105] The support element 25 can have any desired 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 in sections as a spherical segment, as a cylinder, or as a hollow cylinder segment. In the exemplary 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, it can be clearly seen in Fig. 2 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.In the aforementioned projection, an outer edge of the support surface 8 and an inner edge of the contact surface 5 are therefore congruent, so that these surfaces intersect each other.

[0106] In Fig. 3, the connecting part 3 is inserted into a sanitary fitting 9 together with a jet regulator 2. To produce this arrangement, the connecting part 3 was first inserted through the outlet opening of the sanitary fitting 9 into the interior of the sanitary fitting 9. The jet regulator 2 was then screwed in. The connecting part 3 inserted into the interior is clamped with part of a jacket surface of the support element 25 by a ring formed on a side of the sanitary fitting 9 opposite the outlet opening and protruding from the wall of the sanitary fitting 9 into the interior of the latter. The jacket surface of the support element 25 serves as a means for producing a positive and / or non-positive connection 30.This means for producing a positive and / or non-positive connection 30 is designed as a locking lug on a preferably resilient locking tongue 33 which has the locking lug and is provided with two slots 32. The ring projecting into the interior serves as a cooperating countermeasure 31 of the sanitary fitting 9 in order to hold the connecting part 3 in the sanitary fitting 9. The countermeasure 31 acts on a side of the connecting part 3 facing away from the outflow opening 24. Due to the means for producing the positive and / or non-positive connection 30 and the countermeasure 31, the connecting element 3 can be easily held in the sanitary fitting 9, in particular without slipping, while the jet regulator 2 is being screwed in.

[0107] The jet regulator 2 has a thread 16, with which the jet regulator 2 is screwed into a mating thread in the sanitary fitting 9. The connecting part 3 and the jet regulator 2 are arranged such that the jet regulator 2 lies flat and tightly against the contact surface 5, which is designed as a sealing surface 6, and exerts a contact pressure along the axis A3 on the contact surface 5. This pressure acts through the connecting part 3 and in particular through the support element 25 on the support surface 8, which rests against a complementarily designed mating surface of the sanitary fitting 9. The internal thread of the sanitary fitting 9 is thus used to produce a fluidic connection between the connecting part 3 and the jet regulator 2, the connecting part 3 being pressed in between the jet regulator 2 and the sanitary fitting 9.

[0108] The figures described below show, in particular, various design variants of a connecting part 3 described here. In the individual design variants, individual features according to the invention may not be shown. However, all of the features described here are transferable to each of the variants shown.

[0109] The connecting part 3 shown in Fig. 4 is very similar to the connecting part 3 shown in Figs. 1 to 3. Therefore, only the differences between these two design variants are described. In particular, the connecting part 3 shown in Fig. 4 differs from the connecting part 3 shown in Figs. 1 to 3 in 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 and the first axis A1 and the third axis A3 are not aligned orthogonally to one another, but rather the first axis A1 is oriented slightly diagonally, so that an angle of more than 90° is formed between the first axis A1 and the second axis A2 or between the first axis A1 and the third axis A3, which angle lies below the axis A1 in Fig. 4.

[0110] 1 to 3, in the case of the connecting part 3 shown in Fig. 4 the means for producing the positive and / or non-positive connection 30 is designed with a locking lug projecting outwards from a section of the outer surface of the support element 25. This locking lug engages behind the counter element 31 designed as the ring, at least in sections. To enable the connecting part 3 to be easily inserted, the support element 25 has slots on both sides of the section with the locking lug, viewed in the circumferential direction. The section with the locking lug can therefore be resiliently deformed as it passes the counter element 31. To clarify the connection mechanism, the section shown in Fig. The embodiment of the connecting part 3 shown in Fig. 4 with the means for producing the positive and / or non-positive connection 30 is shown in an additional illustration in Fig. 34.The embodiment of the sanitary fitting 9 with the counter element shown in Fig. 4 is also shown in another Fig. 35.

[0111] 1 to 3, it cannot be seen that the contact surface 5 is set back from the wall of the hose receptacle 4 in the connecting part 3 shown in Fig. 4. However, the foot region 15 has a lower height than the head region 14, so that the connecting part 3 shown in Fig. 4 is nevertheless flat overall and can be inserted into a flat sanitary fitting. For particularly space-saving and simple insertion, the connecting part 3 has a bend at the transition from the contact surface 5 to the hose receptacle 4. The connecting part 3 is inserted into the sanitary fitting slightly rotated clockwise around the aforementioned bend, so that the foot region 15 of the connecting part 3 is inserted slightly rotated upwards in the intended installation situation shown.The sanitary fitting into which the connecting part 3 is inserted has an interior space geometrically adapted to the shape of the connecting part 3.

[0112] 5 and Fig. 6 also has a strong similarity to the connecting part 3 shown in Fig. 1 to Fig. 3 and in particular to the connecting part 3 shown in Fig. 4, which is why only the differences are described below. As in the exemplary embodiment shown in Fig. 4 and described above, the angle between the head region 14 and the foot region 15 in the exemplary embodiment shown in Fig. 5 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 somewhat more steeply to one another than in the exemplary embodiment shown in Fig. 4. For example, an angle between the first axis A1 and the second axis A2 or between the first axis A1 and the third axis A3 in the exemplary embodiment shown in Fig. 5 and Fig. 6 is greater than the corresponding angle in the embodiment shown in Fig.4 shown embodiment.

[0113] Even in the connection part 3 shown in Fig. 5 and Fig. 6, it cannot be seen that the contact surface 5 is set back from the wall of the hose receptacle 4. However, the foot region 15 of the connection part shown in Fig. 5 and Fig. 6 also has a lower height than the head region 14 and the above-described kink 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 Fig. 5 - can be inserted into a flat sanitary fitting, in particular rotated clockwise.

[0114] The support element 25 of the embodiment shown in Fig. 5 and Fig. 6 is geometrically modified from the support element of the embodiments shown in Fig. 1 to Fig. 3 and in Fig. 4. The support element 25 shown in Fig. 5 and Fig. 6 also has a substantially hollow cylindrical basic shape. The support element 25 additionally has a stepped structure on a side of the connecting part 3 facing away from the contact surface 5. In the connecting part 3 shown in Fig. 5 and Fig. 6, the support element 25 has three steps. However, more or fewer than three steps can also be formed. In particular, the steps of the stepped structure can be formed parallel to the contact surface 5 and in particular each form a portion of the support surface 8. The steps can have a substantially equal height.Due to the stepped design, it is possible to form a particularly large support surface 8 on the support element 25, while at the same time the height of the support element 25 is extremely low. This allows the connecting part 3 to still be insertable into a flat sanitary fitting. The steps can also be used as a rotation lock, in particular against a torque applied to the contact surface 5 and / or the sealing surface 6.

[0115] The stepped structure of the support element 25 is generally not limited to support elements with a substantially hollow, cylindrical basic shape, but can also be advantageously formed in differently designed 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, so that a structure similar to a sawtooth profile is formed.

[0116] The sanitary fitting shown in Fig. 5, into which the connecting part 3 is inserted, has an interior geometrically matched to the shape of the connecting part 3. The sanitary fitting is designed to be particularly flat.

[0117] The embodiment of the connecting part 3 shown in Fig. 7 also has a strong similarity to the connecting part 3 shown in Figs. 1 to 3, which is why only the differences are described below. In the embodiment shown in Fig. 7, the foot region 15 is essentially in the shape of a hollow truncated cone. Above the hollow truncated cone-shaped foot region 15, the support element 25 is in the shape of a spherical segment with the support surface 8. A substantially hollow cylindrical support element shown in Figs. 1 to 6 does not have the embodiment of the connecting part 3 shown in Fig. 7, although this can be designed in addition to or as an alternative to the support element 25 described here and shown in Fig. 7.

[0118] Fig. 8 shows a further embodiment of a connecting part 3 described here. In the embodiments of a connecting part 3 shown in Figs. 1 to 7, the support element 25 is formed in one piece and in particular of the same material as the base body 22, or formed thereon. As described, this results in particularly high mechanical stability of the connecting part 3. In the embodiment of a connecting part 3 shown in Fig. 8, the support element 25 is not formed in one piece with the base body 22 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.

[0119] In particular, the support element 25 shown in Fig. 8 has a pin-shaped configuration, 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 introduced in a counter-shape, which here is for example complementary, in the foot region 15 of the connecting part 3. 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 connection and / or by means of a clip connection. The support element 25 shown in Fig. 8 is in particular oriented with respect to the foot region 15 and the contact surface 5 in such a way that a force introduced into the contact surface 5 along the axial direction acts along the longitudinal axis of the support element 25.In particular, 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. For better 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, which, however, are not essential for the connecting part 3. Fig. 9 shows a sanitary installation arrangement 1 according to the invention, which is installed in a sanitary fitting 9.

[0120] The sanitary installation arrangement 1 comprises a jet regulator 2 and a connecting part 3. The connecting part 3 is arranged upstream of the jet regulator 2 in the direction of flow. The jet regulator 2 has a thread 16 which is screwed to an internal thread 20 of the sanitary fitting 9. The connecting part 3 has a hose receptacle 4 into which a flexible hose 7 is inserted. The connecting part has a contact surface 5 which is designed in the axial direction for the jet regulator 2. The contact surface 5 is designed as a sealing surface 6. The connecting part 3 has a support surface 8 by means of which it can be placed in a form-fitting manner on the sanitary fitting 9. The connecting part 3 has a head region 14 and a foot region 15 which are angled towards one another. The head region 14 is the region in which the hose receptacle 4 is formed.The base area 15 is the area against which the jet regulator 2 rests flat. The connecting part 3 has support ribs 17 which are distributed around the circumference. The support ribs 17 are formed between the head area 14 and the base area 15 and ensure stiffening of the connecting part 3. The connecting part 3 further has an anti-twist device 18 which prevents relative twisting of the connecting part 3 against the sanitary fitting 9. The connecting part 3 has retaining lugs 19 arranged on the outside on the circumference, which are suitable for locking with the internal thread 20 of the sanitary fitting 9. The retaining lugs 19 are necessary when assembling the sanitary installation arrangement 1 in order to hold the connecting part 3 in position while a connection is made to the jet regulator 2.

[0121] Fig. 10 shows the sanitary installation arrangement 1 from Fig. 9 installed in the sanitary fitting 9, viewed from above. The connecting part 3 is visible, as well as the head region 14 and the base region 15. The anti-twist device 18 is also visible as a round element. The anti-twist device 18 is designed as a truncated cone here. Alternatively, the anti-twist device 18 can be designed as a stopper.

[0122] Fig. 11 shows a connecting part 3 in a perspective view from the side. In this case, the head region 14 and the foot region 15 are formed at an angle equal to or approximately 90 °. The retaining lugs 19 are arranged laterally around the foot region 15. The hose receptacle 4 is also visible. In the interior of the connecting part 3, in the hose receptacle 4, an internal and circumferential projection is formed which can accommodate a flexible hose 7. The support ribs 17 are formed between the head region 14 and the foot region 15 and stiffen the structure so that no deformation occurs when water flows through. The support surface 8 is formed between the connecting part 3 and the sanitary fitting 9 (not shown here). The contact surface 5 is formed on the lower part of the connecting part 3 and is designed as a sealing surface 6 in the specific example.The retaining lugs 19 are arranged at an angle to the base region 15 of the connecting part 3, wherein the angle is less than 45° to a main axial direction of the base region 15. The anti-twist device 18 is formed on a cylindrical part of the head region 14 and prevents the connecting part 3 from twisting relative to the sanitary fitting 9 (not shown here).

[0123] Fig. 12 shows another connecting part 3 in a view from below. The connecting part 3 has a receiving space

[0124] 11, into which a non-circular sealing means 12 is pressed. The receiving space 11 has a double-walled section 10. Retaining projections 13 are formed on the receiving space 11 and are intended to prevent the sealing means 12 from falling out axially. The retaining lugs 19, which are necessary for mounting the sanitary installation arrangement 1, are formed in the base area 15. The supporting ribs 17 stiffen the connecting part 3 and are formed between the head area 14 and the base area 15. The head area 14 and the base area 15 are arranged at an angle to one another. This angle is necessary due to the structural specifications of the sanitary fitting 9 (not shown here). The sealing means 12 ensures a seal between the space in which water flows and another space in which no water may flow. The sanitary installation arrangement 1 is designed in such a way that a flow of water outside the sanitary installation arrangement 1 is to be prevented.This is necessary to prevent the sanitary fitting 9 from requiring approval for drinking water. This saves costs while at the same time fulfilling full functionality. The hose receptacle 4 is also visible, wherein the hose receptacle 4 has a circumferential projection into which the flexible hose 7 (not shown here) can be inserted. The contact surface 5, which in the specific example is designed as a sealing surface 6, is also visible. The sealing means 12 is non-circular and arranged in the receiving space 11. A non-circular sealing means is particularly advantageous for sealing.

[0125] Fig. 13 shows the connecting part 3 from Fig. 12 in a perspective view from below. The elements have already been described in Fig. 12 and will not be explained again here. The retaining lugs 19, which are formed at an angle to the base region 15, are clearly visible. 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 pressed into the internal thread 20 of the sanitary fitting 9 (not shown here).

[0126] Fig. 14 shows the connecting part 3 from Fig. 12 and Fig. 13 in a sectional view through a middle plane. The anti-twist device 18 can be seen, which is located on the head region 14. The non-circular sealing means 12 can also be seen, which is located in the receiving space 11. The receiving space 11 has a double-wall section 10. The head region 14 and the foot region 15 are angled to one another, the angle being approximately 45°. The support ribs 17 are formed between the head region 14 and the foot region 15.

[0127] Fig. 15 shows a further connection part 3 in a view from above. A reinforcing element 21 can be seen which is circumferential and is located on an outer region of the foot region 15. The head region 14 and the foot region 15 are angled to one another. A single supporting rib 17 is formed between the head region 14 and the foot region 15 (Fig. 16). In addition, retaining lugs 19 can be seen which are arranged at an angle to the main axial axis of the foot region 15. The hose receptacle 4 is also formed in the head region 14. The supporting surface 8 can be seen which is formed between the sanitary fitting 9 (not shown here) and the head region 14 (Fig. 16). In this specific case, the supporting surface 8 is formed directly on the reinforcing element 21. The reinforcing element 21 is designed here as a steel disk.Alternatively, materials other than metals can be used 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 main body 22 is considered to be the combination of the head region 14 and the foot region 15. The reinforcing element 21 is slit through a slot 23, in which the support rib 17 can be arranged.

[0128] Fig. 17 shows the connecting part 3 from Fig. 15 and Fig. 16 in a sectional view through a central plane. An anti-twist device 18 is not formed here. The projection, on which a flexible hose 7 is located or rests in the operating state, is formed in the interior of the head region 14. The head region 14 and the foot region 15 are angled to one another, wherein the angle depends on the structure of the sanitary fitting 9 (not shown here). The reinforcing element 21, which is designed here as a steel disk, rests on an outer side of the connecting part 3. No sealing means is formed on the contact surface 5. Alternatively, the reinforcing element 21 can also consist of materials other than metal, which have a higher strength than the connecting part 3 or the base body 22. The reinforcing element 21 can be in cross-section, i.e.

[0129] The reinforcing element 21 can be L-shaped in the circumferential direction. This enables production as a bent part, in particular a deep-drawn part. Alternatively, the reinforcing element 21 can be rectangular in cross-section. As an alternative to the metal ring, the reinforcing element 21 can be designed as a flanged sleeve or as a cap.

[0130] Fig. 18 shows a further connecting part 3 in a view from below. The connecting part 3 has the elements already described above, which are not explained separately here. The contact surface 5 is designed as a sealing surface 6. The hose receptacle 4 and the internal and circumferential projection are visible.

[0131] Fig. 19 shows the connecting part 3 from Fig. 18 in a perspective view from below. The support ribs 17 are visible, which are located between the head region 14 and the foot region 15. The sealing means 12 is non-circular, in particular T-shaped (see Fig. 20).

[0132] Fig. 20 shows the connecting part 3 from Fig. 18 and Fig. 19 in a sectional view through a central plane. The sealing means 12 is located in the receiving space 11, which has a double-walled section 10. The anti-twist device 18 is also visible. The angled retaining lugs 19 are also visible.

[0133] Fig. 21 shows another connecting part 3 in a side view. The head region 14 and the base region 15 are angled relative to each other. Support ribs 17 are arranged between the two parts 14, 15, which increase the rigidity of the structure. The anti-twist device 18 is visible. In the lower region, against which the jet regulator 2 (not shown here) rests in a sanitary installation arrangement 1 (not shown here), is the contact surface 5, which is designed as a sealing surface 6. The angled retaining lugs 19 running around the outside of the base region 15 are also visible.

[0134] Fig. 22 shows the connecting part 3 from Fig. 21 in a perspective view from across above. The existing elements have already been described above and will not be explained again separately.

[0135] Fig. 23 shows a further connecting part 3 in a side view. The difference between this connecting part 3 and the connecting parts 3 described above is that the head region 14 and the foot region 15 run in a straight line, in particular are not angled to one another. The connecting part 3 does not have any support ribs 17, and is therefore designed without support ribs. In an alternative embodiment, the head region 14 and the foot region 15 can be angled to one another and / or have support ribs. The connecting part 3 has angled retaining lugs 19. In the lower region, the contact surface 5, which is designed as a sealing surface 6, can be seen. A sealing means 12 is also visible. The outer region of the head region 14 is designed as a support surface 8, on which the sanitary fitting 9 (not shown here) is supported. The connecting part 3 does not have an anti-twist device 18.

[0136] Fig. 24 shows the connecting part 3 from Fig. 23 in a perspective view from across above. The connecting part 3 is designed without support ribs. The connecting part 3 does not have an anti-twist device 18. The head region 14 and the foot region 15 are not angled, but rather are formed along a straight line. Angled retaining lugs 19 are visible on the connecting part 3.

[0137] Fig. 25 shows a further connecting part 3 in a perspective view from across above. The connecting part 3 has a head region 14 and a foot region 15. The foot region 15 can be in contact with a jet regulator 2 (not shown here). The head region 14 has a hose receptacle 4 which is designed to receive a flexible hose 7 (not shown here). In the foot region 15 there is also a support surface 8 which rests against a mating surface of a sanitary fitting 9 (not shown here). In addition, resilient spring tongues 27 arranged on the outside are formed on the circumference and are suitable for locking with an internal thread 20 (not shown here) of the sanitary fitting 9 (not shown here). The spring tongues 27 are advantageous for mounting a sanitary installation arrangement 1 (not shown here) in the sanitary fitting 9. Fig. 26 shows the connecting part 3 from Fig .25 in a view from below. Most of the elements have already been described in the figure description for Fig. 25 and will not be explained again here. Only an additional opening 28 is visible here, through which water or a fluid can be conducted. The opening 28 has an oval shape in Fig. 26; alternative shapes are also possible.

[0138] Fig. 27 shows a sectional view through the connecting part 3 from Fig. 25. The head area 14 and the foot area 15 are angled towards each other to enable installation in curved outlets of the sanitary fitting 9 (see, for example, Fig. 28).

[0139] Fig. 28 shows a sanitary installation arrangement 1 with a connection part 3 according to Fig. 25 in an installed state in a sanitary fitting 9. The sanitary installation arrangement 1 comprises a jet regulator 2 and a connection part 3. A contact surface 5 is formed between the connection part 3 and the jet regulator 2. A flexible hose 7 is plugged into the connection part 3 and connects a valve cartridge (not shown here) to the sanitary installation arrangement 1. Water flows only in the flexible hose 7 and the sanitary installation arrangement 1. The support surface 8 supports the connection part 3 on a counter surface of the sanitary fitting 9.

[0140] Fig. 29 shows a further embodiment of a connecting part 3 in a perspective view from below. The connecting part 3 comprises a head region 14 and a foot region 15. The head region 14 and the foot region 15 are arranged straight relative to one another, as in the embodiment shown in Fig. 23. In an alternative embodiment, the head region 14 and the foot region 15 can be designed at an angle to one another. In the upper region of the figure, a hose receptacle 4 can be seen, into which a flexible hose 7 (not shown here) can be inserted. The connecting part 3 has a tool attachment 29 which is designed to conduct liquid. In the present example, the tool attachment 29 is designed as a hexagon socket. In alternative embodiments, the tool attachment 29 can be designed as a square socket.A suitably contoured removal tool, for example an Allen key, can be inserted into the tool attachment 29 in order to transfer the connecting part 3 from an assembled state in the sanitary fitting 9 into a disassembled state, in particular to lever out the connecting part 3.

[0141] Fig. 30 shows the connecting part 3 from Fig. 29 in a view from below. The explanations for Fig. 29 also apply here accordingly. The liquid-carrying tool attachment 29 can be seen, in which the through-opening 28 is formed. The water or the fluid flows in the through-opening 28. In the foot area 15, resilient spring tongues 27 are arranged on the outside circumferentially and are advantageous for the assembly and disassembly of the sanitary installation arrangement 1 in the sanitary fitting 9.

[0142] Fig. 31 shows the connecting part 3 from Fig. 29 in a side view. The head area 14 and the foot area 15 are straight relative to each other, this is advantageous for straight sanitary fittings 9 (see Fig. 32) with straight outlets. The resilient spring tongues 27 arranged on the outside of the circumference are visible. In addition, the support surface 8 is visible, which supports the connecting part 3 on a counter surface of a sanitary fitting 9 (see Fig. 32). Fig. 32 shows a sanitary installation arrangement with a

[0143] Connecting part 3 according to Fig. 29 in an installed state in a sanitary fitting 9. The sanitary installation arrangement 1 comprises a jet regulator 2 and a connecting part 3.
