Background Art

[0005] Jet regulators or more generally hygienic inserts which comprise, for example, a contact surface cooperating with the inside of a sanitary fitting, for example in order to form a transition between sanitary fitting and jet regulator in the screwed-in state. Summary of the invention

[0006] The object of the present invention is to improve the handling properties of hygienic inserts.

[0007] To achieve this object, the invention proposes the features of claim 1. In particular, according to the invention, for a sanitary insert component, which comprises a contact surface formed on a housing component and which forms a stop for a connecting movement, in particular an insertion or screwing movement, of the sanitary insert component, it is proposed that the contact surface is formed at the level of at least one annular region of the outlet structure of the sanitary insert component (or even at the level of the outlet structure) and is arranged on the sanitary insert component in such a way that the contact surface can interact with a flange on the outlet opening of the jet regulator receptacle of the sanitary fitting.

[0008] The connecting movement can also be, for example, snap-on, crimp, plug-in, twist-on (eg bayonet closure) or a combination of one or more of these connecting movements with one another and / or with other connecting movements.

[0009] By forming the contact surface at the level of at least one annular region of the outlet structure, a concealed hygienic insert can be formed which, for example, ends with a radially outer annular region together with the sanitary fitting and / or can be sunk in the sanitary fitting for the most part.

[0010] The folded edge can be the result of a non-dimensionally stable processing step and / or can be characterized as the result of burr removal. The folded edge can thus be, for example, an inclined surface, for example a chamfer and / or a transition radius. Accordingly, it can be provided, for example, that the contact surface also has an inclined surface, in particular a chamfer, which can interact with the folded edge.

[0011] It is very advantageous that, in order to generate the interaction between the sanitary fitting and the hygienic insert component, in particular the jet regulator, by means of the correspondingly arranged contact surfaces, it is not necessary, for example, to carry out additional processing and / or production steps on the sanitary fitting. This improves the usability characteristics. It is also advantageous that, according to this, a corresponding jet regulator or more generally a hygienic insert component can be easily inserted into an already existing sanitary fitting. Thus, a standardized receptacle can already be used for jet regulators and other hygienic insert components.

[0012] The contact surface can be particularly advantageously arranged here, for example, on a fold on the outlet opening of the jet regulator receptacle of the sanitary fitting in such a way that a fluid seal can be achieved between the sanitary insert, in particular the jet regulator, and the sanitary fitting.

[0013] By forming a stop for a connecting movement, in particular an inserting or screwing movement, of a jet regulator or another hygienic insert part, the contact surface can advantageously reversibly enable, for example, a predetermined use in which the hygienic insert part, in particular the jet regulator, is, for example, completely screwed into a sanitary fitting. Thus, inappropriate screwing in and / or unscrewing of the hygienic insert part into and out of the sanitary fitting, which could, for example, damage the thread of the hygienic insert part and / or the sanitary fitting, can also advantageously be largely prevented.

[0014] The arrangement at the height of at least one annular region of the outlet structure can be characterized, for example, in that the outlet structure does not substantially protrude or sink at least in the annular region when the contact surface is aligned, coincident or otherwise cooperating with the end of the sanitary fitting in the flow direction.

[0015] The discharge structure can be convex or concave inwards or shaped in a complex manner or can continue flatly or in a stepped manner from the annular region. Due to the arrangement at the height of the discharge structure, the rim can be designed to be invisible, so that the sealing device can be designed to be concealed. An attractive visual image can thus be achieved. In an advantageous embodiment, the discharge structure can be flat on the outflow side, but a coin slot (including a bulging discharge structure) is also conceivable, and the drip edge can also protrude slightly for better flow separation.

[0016] Preferably, the contact surface is formed circumferentially. Thus, for example, it can be advantageously achieved that a sanitary insert, in particular a jet regulator, can interact with a sanitary fitting at every contact point of the contact surface over the entire circumference. Thus, the formation of leakage paths can be prevented.

[0017] Alternatively or additionally, in order to achieve the object, the invention provides the features of the parallel claims for a hygienic insert, in particular a jet regulator. Therefore, in particular in order to achieve the object, in a hygienic insert, in particular a jet regulator, in particular the hygienic insert, in particular the jet regulator mentioned and / or claimed, it is provided according to the invention that the contact surface is formed at least partially by an elastic material formed on the housing part.

[0018] This makes it possible to arrange the sealing body made of elastic material in a way that it cannot be lost. This can simplify assembly.

[0019] The elastic material can be, for example, an elastomer body. This can, for example, allow simple contact and / or sealing even on uneven or rough surfaces.

[0020] The shaping of the elastic material can be carried out, for example, by injection molding.

[0021] The housing part and the elastic material formed thereon can form, for example, the lowermost outer circumferential edge of a hygienic insert, in particular a jet regulator.

[0022] Alternatively or additionally, in order to achieve the object, it is proposed that the contact surface is formed at least partially of a non-circular elastic material, preferably adapted to the outer contour of the hygienic insert, in the form of a wire cross section. The non-circular, for example non-round, contour makes it possible to fix the elastic material in a positively locking manner and / or to form or install a suitable contact surface. The wire cross section can be characterized, for example, in that it is perpendicular (at every point) to the direction of extension of the surrounding structure.

[0023] It is therefore particularly advantageous that the jet regulator or the other hygienic insert can, for example, already during screwing in and / or in the screwed-in state, lie against an external structure of the sanitary fitting, such as a fold, due to a certain elasticity of the elastic material, which fold, for example, forms a contact point of the contact surface. It is also advantageous that other sections of the jet regulator or the other hygienic insert, such as the outlet structure, can be made of another material, which in turn can produce a high degree of variability in the choice of material.

[0024] Furthermore, it can be provided, for example, that the elastic material is designed integrally with the outlet structure and the housing part of the jet regulator or another hygienic insert. The outlet structure here, for example, forms the last section of the jet regulator or another hygienic insert, from which the water flows out. It can be provided, for example, that the elastic material thus forms the jet outlet opening of the outlet structure.

[0025] In this case, it is particularly advantageous that, in addition to or as an alternative to the already described advantages of the adhesion of the contact surface to, for example, a flange of a sanitary fitting, such a variant allows the selection of an elastic material on which, for example, no stubborn calcium deposits can form. Thus, for example, clogging of the jet outlet opening by calcium deposits can be avoided and the durability of the jet regulator or another sanitary insert can be increased.

[0026] In an advantageous embodiment, it can be provided that the elastic material is a thermoplastic.

[0027] Thus, for example, if the elastic material is designed integrally with the outlet structure, it can be produced particularly advantageously by using thermoplastics, for example by means of an injection molding process, in particular in large quantities.

[0028] Alternatively or additionally, it can be provided that the elastic material is silicone. This makes it easier to comply with drinking water regulations, for example.

[0029] Silicone offers the absolutely essential advantage of physiological compatibility, particularly in the area of ​​jet regulators and in the associated permanent contact with drinking water. In addition, silicone remains (thermo)mechanically stable, for example, over a very large temperature range, so that—as is often the case in sanitary fittings—hot and very cold water can also pass through the outlet structure without any problems.

[0030] In an advantageous embodiment, it can be provided that the contact surface bears against the sanitary fitting during intended use and is shaped such that at least at contact points located within the contact surface, the contact surface is oriented at an angle to the axial direction and the radial direction.

[0031] The axial direction can be defined here, for example, by the longitudinal direction of the jet regulator or of another hygienic insert component.

[0032] By means of a corresponding orientation of the at least one contact point within the contact surface at an angle to the axial direction and to the radial direction, the radial direction being in particular at right angles to the axial direction, it is possible to generate, in a particularly advantageous manner, for example a hermetic and / or in particular a fluid-tight seal of the gap dimensions, for example between a sanitary fitting and a sanitary embedded component and / or at a transition between a sanitary fitting and a sanitary embedded component, in particular a jet regulator.

[0033] It is also advantageous that, for example, water can be prevented from penetrating into the gap dimensions, for example by lateral outflow of water or by capillary action. Water penetrating into the corresponding gap dimensions can, for example, promote the formation of calcium deposits between the hygienic insert, in particular the jet regulator, and the sanitary fitting, which in turn makes it more difficult to screw the jet regulator or another hygienic insert into or out of the sanitary fitting without problems and without damage. It is also particularly advantageous that, by correspondingly orienting the contact surfaces and the seals, in particular fluids, generated thereby, in the axial and radial directions, the likelihood of the formation of calcium deposits in difficult-to-access gaps can be significantly reduced and a problem-free screwing in and / or out of the jet regulator or another hygienic insert can be facilitated.

[0034] Preferably, the contact surface is oriented at an angle relative to the axial direction and the radial direction at each contact point within the contact surface. Thus, for example, a circumferentially constant, preferably fluid-tight, effective connection between a sanitary insert, in particular a jet regulator, and a sanitary fitting can be advantageously generated.

[0035] In a further advantageous embodiment, it can be provided that the air channel is formed on the hygienic insert part, in particular on the jet regulator.

[0036] The air filling channel here, for example, brings air into the mixing stage. It is thus possible to mix air into the water flow that finally passes through the jet regulator or the other hygienic insert, which is particularly advantageous, as, for example, water consumption can be reduced.

[0037] In a further advantageous embodiment, it can be provided that a tool attachment is formed on the housing part, which serves to introduce a torque for screwing in and / or unscrewing the jet regulator or the further hygienic insert part.

[0038] The tool attachment part can be formed, for example, by at least one air filling channel, for example, the air filling channel already described. The tool attachment part can also be formed, for example, in the discharge structure.

[0039] Particularly advantageously, a jet regulator having, for example, an external thread which is screwed into an internal thread of the sanitary fitting can thus be installed initially without problems or replaced in the event of wear and / or repair.

[0040] In a further advantageous embodiment, it can be provided that the contact surface extends radially outside an axial projection of the threaded region.

[0041] This can particularly advantageously significantly reduce the possibility of water, for example, as already mentioned, penetrating into the gap between the sanitary fitting and the jet regulator below the threaded area by lateral outflow of water and / or by capillary action. If the water, for example, enters the threaded area and thus the thread between the jet regulator and the sanitary fitting, for example, calcium deposits can form, which prevent the sanitary insert, in particular the jet regulator, from being screwed in and / or screwed out without damage.

[0042] In an advantageous design, it can be provided that the sanitary insert, in particular the jet regulator, has an outlet structure extending in the radial direction at its axial end, which is coordinated with the axial end of the sanitary fitting and / or does not protrude outward at least in an outer annular region when the sanitary insert, in particular the jet regulator, is in a screwed-in state.

[0043] It is thus possible, for example, for the sanitary insert part, in particular the jet regulator, to rest flatly on the sanitary fitting.

[0044] It is particularly advantageous here that even if water escapes laterally from the outlet structure, there is no increased risk of water entering into the gap dimensions between sanitary insert components, in particular the jet regulator, and the sanitary fitting.

[0045] In this case, it can be provided, for example, that an axial extent of the outlet structure, for example an inner delimitation of the outlet structure, is in a certain relationship to a size or arrangement of the contact surface.

[0046] In a further advantageous embodiment, it can be provided that for screwing the sanitary insert component, in particular the jet regulator, into and / or out of the sanitary fitting, a thread is formed which corresponds to a mating thread of the sanitary fitting.

[0047] Here, for example, it can be provided that the sanitary insert, in particular the jet regulator, has an external thread, by means of which the sanitary insert can be screwed into and / or screwed out of a matching internal thread of a sanitary fitting, for example. It can also be provided, for example, that the sanitary insert, in particular the jet regulator, has an internal thread, by means of which the sanitary insert can be screwed into and / or screwed out of a matching external thread of a sanitary fitting, for example.

[0048] In this way, a sufficiently stable and yet at the same time easily releasable non-positive connection between a sanitary insert component, in particular a jet regulator, and a sanitary fitting can be produced particularly advantageously.

[0049] In an advantageous embodiment, it can be provided that the sanitary insert part, in particular the jet regulator, bears against the inner side of the sanitary fitting via the contact surface during intended use.

[0050] As already mentioned, the intended use can define, for example, a state in which the sanitary insert component, in particular the jet regulator, is screwed completely into the sanitary fitting and thus up to a stop.

[0051] It is particularly advantageous if, for example, the contact surface, preferably formed by the elastic material already described, is arranged on the folded edge and thus on the outlet opening of the jet regulator receptacle in such a way that it additionally rests on the inner side of the sanitary fitting. Thus, even if, for example, small amounts of water enter the gap at the transition between the sanitary fitting and the sanitary insert, in particular the jet regulator, it can be prevented from entering further higher areas, for example in the area of ​​the thread.

[0052] In an advantageous embodiment, it can be provided that the contact surface which bears against the sanitary fitting during intended use is separated from the end surface forming the outlet structure by a transition forming an acute angle.

[0053] Here, for example, it can be provided that the contact surface forms an angle of less than 90° with the end face in the completely screwed-in state in the radial direction and with the axial direction. Such an angle can, for example, help to make it more difficult or prevent water from penetrating into a gap formed for receiving a sanitary fitting. It is particularly advantageous if the acute angle is coordinated with the folded edge. This can, for example, allow simple contact with a sanitary fitting.

[0054] The acute-angled structure of the contour can advantageously allow the jet regulator to be lowered into the sanitary fitting or to be aligned with the sanitary fitting without protruding or virtually protruding (at least in the outer lateral or radial edge regions), without requiring complex changes to the transition between the sanitary fitting and the sanitary embedded component, in particular the jet regulator.

[0055] Alternatively or additionally, in order to achieve the object, the invention provides the features of the parallel claims for the use of the already claimed hygienic insert component, in particular a jet regulator. In particular, the invention therefore provides that the contact surface is in an active relationship with the folded edge. This allows a simple sealing of the gap between the inserted jet regulator and the receiving sanitary fitting, in particular against the infiltration or penetration of water, which escapes from the hygienic insert component, in particular the jet regulator, and penetrates laterally on the surface of the hygienic insert component.

[0056] The advantages already mentioned can thus be achieved particularly advantageously.

[0057] Alternatively or additionally, in order to achieve the object, the invention provides the features of the parallel claims for a sanitary fitting comprising the already claimed hygienic insert, in particular a jet regulator. In particular, the invention therefore proposes that the elastic material is designed such that, in the intended use when the hygienic insert, in particular the jet regulator, is completely screwed with an outer thread into an inner thread of the sanitary fitting, the transition between the contact surface of the hygienic insert, in particular the jet regulator, and the inside of the sanitary fitting is fluid-tight by the elastic material.

[0058] The elastic material can be formed, for example, by an elastomer body, for example a silicone elastomer body or a thermoplastic elastomer body.

[0059] Particularly advantageously, the elastic material can thus, for example, lie against the or a folded edge of the sanitary fitting in the circumferential direction. The folded edge can be, for example, a manufacturing-related chamfer, in particular a chamfer or a transition radius. Particularly advantageously, the transition between the sanitary fitting and the sanitary insert, in particular the jet regulator, can thus be fluid-tight due to the angled orientation of the contact surfaces in the axial and radial directions.

[0060] It is thus possible to particularly advantageously prevent, for example, the penetration of water and thereby prevent a clogging of the gap at the transition between the sanitary fitting and the sanitary insert component, in particular the jet regulator.

[0061] As an alternative or in addition to the solution of the object, the invention provides the features of the parallel claims for the kit. In particular, a kit is provided for achieving the object, which comprises a removal tool and the above-mentioned and / or claimed sanitary insert part, in particular a jet regulator and a sanitary fitting, wherein the sanitary insert part can be unscrewed from the sanitary fitting and / or screwed onto the sanitary fitting by means of the removal tool, wherein the removal tool is designed to introduce a torque on a tool attachment of a housing part in order to screw in and / or unscrew the sanitary insert part.

[0062] In this way, a point of action for the tool that is frequently flowed through or overflowed can be provided, which point of action is less prone to calcification.

[0063] In a further advantageous embodiment, it can be provided that the removal tool is designed to engage in at least two channel walls of the hygienic insert part, in particular a housing part of a jet regulator, which form the tool attachment and delimit the filling channel.

[0064] The constructed air channel thus extremely advantageously provides multifunctionality, namely the function for delivering air to the mixing stage and thus into the water flow and / or the function of a tool attachment portion. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Figure 1 A jet regulator, denoted as a whole by 1, is shown as an example of a hygienic insert, comprising an outlet structure 3 formed on the jet regulator 1, which forms the water outlet 2. The outlet structure 3 is formed at an axial end 13 of the jet regulator 1 and extends in a radial direction 14. It can therefore be said that the outlet structure 3 forms an end face 15 of the jet regulator 1.

[0077] Other exemplary embodiments may have additional components to the jet regulator 1 shown, which are detachably or loosely connected to the jet regulator, such as a screw sleeve or a nozzle piece.

[0078] Figure 1 The jet regulator 1 has a threaded area 5 on the housing part 4, which includes an external thread 6 formed in this embodiment. This external thread is used to screw the jet regulator 1 into a corresponding internal thread 7 of a sanitary fitting 8 (see Figure 7 , 8 , 9) and / or unscrewed from the internal thread.

[0079] It can therefore be said that in order to screw into and / or unscrew from the sanitary fitting 8, a thread 10 is formed on the jet regulator 1 that matches the matching thread 9 of the sanitary fitting 8 (see Figure 7 , 8 , 9).

[0080] In addition, according to Figure 1 The jet regulator 1 is formed with a circumferential contact surface 11 which extends radially outside the axial projection of the threaded region 5 and thus radially outside the external thread 6 .

[0081] The contact surface 11 directly radially adjoining the outlet structure 3 is inclined in this exemplary embodiment and forms a chamfer 12. This geometric design results in the contact surface 11 forming a stop for the screw-in movement of the jet regulator 1, as in Figure 7 , 8 and as further shown in 9.

[0082] In this exemplary embodiment, the contact surface 11 is connected integrally to the housing part 4 and the outlet structure 3 and is produced from solid plastic.

[0083] Furthermore, it can be seen that an O-ring 16 is formed on the jet regulator 1 between the contact surface 11, the outlet structure 3 and the threaded area 5 including the external thread 6. The O-ring 16 acts as a fluid seal to prevent water from penetrating during intended use and thus as soon as the external thread 6 of the jet regulator 1 is completely screwed into the internal thread 7 of the sanitary fitting 8 (see Figure 8 , 9 ).

[0084] It can be seen that the contact surface 11 is formed at the level of at least one annular region 32 of the outlet structure 3. The outlet structure 3 continues the annular region 32 in a flat manner radially inwards.

[0085] Figure 2 A further exemplary embodiment of a jet regulator 1 is shown. Components and functional units which are similar or identical in function and / or structure to the previous exemplary embodiments are denoted by the same reference numerals and are not described separately again.

[0086] Different from the above-mentioned embodiment, a positive seal 17 is provided on the jet regulator 1 for fluid sealing instead of the O-ring 16. The positive seal 17 partially contacts the contact surface 11, which is more resistant than the O-ring 16 ( Figure 1 ) can be better assembled and an improved sealing effect can be achieved.

[0087] It can be seen that the elastic material 18 has a non-circular wire cross section, with which it is adapted to the outer contour shape of the jet regulator 1 .

[0088] according to Figure 3 The embodiment of the embodiment of the invention differs from the previous embodiments in that the contact surface 11 is formed at least partially by an elastic material 18 formed on the housing part 4. The elastic material 18 in this embodiment is silicone 19 or a thermoplastic elastomer (TPE) 20. The outlet structure 3 is also made of a hard material.

[0089] It can therefore be said that the elastic material 18 is a thermoplastic 21 and / or a silicone 19 .

[0090] The fluid sealing device is not provided by an O-ring 16 ( Figure 1 ) or shape sealing device 17 ( Figure 2 ), but is formed by the chamfer 12 of the contact surface 11 itself.

[0091] Different from following Figure 3 An embodiment of Figure 4 A jet regulator 1 is shown, whose contact surface 11 is formed integrally with the outlet structure 3 and is made of an elastic material 18 , in this exemplary embodiment solid rubber. In this exemplary embodiment, the contact surface 11 is also fluid-tight by the chamfer 12 .

[0092] Figure 5 and Figure 6 Shown in accordance with Figure 1 and Figure 3 A partial cross-section of an embodiment of a jet regulator 1, including a discharge structure 3, a contact surface 11, an O-ring 16 ( Figure 5 ), the elastic material 18 of the contact surface 11 ( Figure 6 ) and a threaded region 5 formed on the housing part 4 and comprising an external thread 6.

[0093] exist Figure 6 It can be seen in FIG. 1 that the contact surface 11 is arranged at the level of an annular region 32 of the drainage structure 3 . The annular region 32 has a drip edge 33 .

[0094] Figure 7 Shown in accordance with Figure 3 1 is an embodiment of the specified use of the jet regulator 1. The jet regulator 1 is completely screwed into the internal thread 7 of the sanitary fitting 8 via the external thread 6. The contact surface 11 forms a stop for the screw-in movement of the jet regulator 1. In order to screw in and / or unscrew the jet regulator 1, a tool attachment 29 is formed on the housing part 4. The tool attachment 29 is formed in this embodiment by a channel wall 31 that defines the filling channel 30, and a removal tool (not shown in detail) for introducing torque can be embedded in the channel wall.

[0095] Furthermore, it can be seen that the contact surface 11 is arranged on the jet regulator 1 in such a way that it interacts with a flange 22 on the outlet opening of a jet regulator receptacle 23 of the sanitary fitting 8 .

[0096] In the intended use shown here, the contact surface rests on the sanitary fitting 8 and is shaped in such a way that it is oriented at an angle to the axial direction 25 and the radial direction 14 at each contact point 24 located within the contact surface 11 .

[0097] Furthermore, it is shown that the jet regulator 1 rests with the contact surface 11 on the sanitary fitting 8 , in this exemplary embodiment on the inner side 27 of the sanitary fitting 8 .

[0098] It can also be seen that the outlet structure 3 in the screwed-in state shown is coordinated with the axial end 26 of the sanitary fitting 8 in the outer annular region of the jet regulator 1 and does not protrude outward. The contact surface 11 resting on the sanitary fitting 8 is separated from the end face 15 formed by the outlet structure 3 by an acute-angled transition 28.

[0099] Because according to Figure 3 The contact surface 11 of the jet regulator is as already described in Figure 3It is described in the figure that it is made of elastic material 18, so it can be said that the transition 28 between the contact surface 11 of the jet regulator 1 and the inner side 27 of the sanitary fitting 8 is fluid-tight by the elastic material 18. The contact surface 11 is therefore closely attached to the shape of the folded edge 22 during the specified use, thereby providing sealability.

[0100] Figure 8 and 9 In contrast to the previous exemplary embodiments, the embodiment shown in full section in the state in which the sanitary fitting 8 is screwed in is shown in the intended state. Figure 1 Side view of the jet regulator 1 ( Figure 8 ) and perspective bottom view ( Fig. 9 In this case, the O-ring 16 is deformed accordingly due to the friction-locking connection between the jet regulator 1 and the sanitary fitting 8 and is fluid-tight.

[0101] Therefore, a hygienic embedded component, in particular a jet regulator 1, is provided, comprising a preferably circumferential contact surface 11 formed on a housing part 4, which forms a stop for the screw-in movement of the jet regulator 1, wherein according to the invention, the contact surface 11 abuts against a folded edge 22 of the sanitary fitting 8 in the screwed-in state, cooperates with the folded edge and is formed in such a way that at at least one contact point 24 located within the contact surface 11, the contact surface 11 is oriented at an angle relative to the axial direction 25 and the radial direction 14 in order to preferably provide a fluid-tight seal for the transition 28 between the contact surface 11 and the sanitary fitting 8.
