Description

[0001] Adapter sleeve, in particular for attaching a sanitary function cartridge to a fitting mouthpiece

[0002] It is known to provide fittings with a screw-on fitting mouthpiece on a fitting outlet, into which a sanitary function cartridge, for example a jet regulator, can be accommodated. A circumferential retaining projection is formed on the outside of the sanitary function cartridge, which rests on a corresponding shoulder of the fitting mouthpiece in order to press the function cartridge against the fitting when the fitting mouthpiece is screwed on.

[0003] It is also known to provide sanitary function cartridges with an external thread on the outside in order to screw the function cartridge directly into a water outlet of a fitting and to dispense with a fitting mouthpiece.

[0004] The invention is concerned with expanding the mounting options for functional cartridges on fittings.

[0005] According to the invention, the features of claim 1 are provided for solving this problem in an adapter sleeve. In particular, to solve the aforementioned problem in the adapter sleeve, the invention proposes that the adapter sleeve be designed with an outwardly projecting retaining projection on an upper axial section and with an internally accessible fastening means on a lower axial section. This creates an adapter which allows a functional cartridge of any design to be easily mounted on a standardized fitting mouthpiece. The adapter sleeve can therefore be designed to attach a sanitary functional cartridge, in particular the functional cartridge already mentioned, to a fitting mouthpiece, in particular the standardized mouthpiece already mentioned.

[0006] The functional cartridge can be, for example, a jet regulator. However, other functional cartridges, such as valves, temperature-controlled devices, or other functional cartridges, can also be used to advantage.

[0007] The accessibility of the fastening device from the inside has the advantage that the inserted functional cartridge can cooperate directly with the fastening device.

[0008] The terms "upper axial section" and / or "lower axial section" can, for example, refer to a typical or preferred position of use in which the water flows from top to bottom. The terms "top" and "bottom" can also refer to a flow direction.

[0009] In one embodiment of the invention it can be provided that the upper axial section is, for example, an inflow-side axial section. This can make it possible, for example, that the adapter sleeve can be fastened to the fitting mouthpiece on an inflow side. Alternatively or additionally it can be provided that the lower axial section is, for example, an outflow-side axial section. This can make it possible, for example, that the adapter sleeve can be connected to the sanitary function cartridge on the outflow side. Alternatively or additionally it can be provided that the upper axial section is arranged upstream of the lower axial section. This can make it possible, for example, that water in the direction of flow first flows through the upstream upper axial section before it flows through the lower axial section.

[0010] The upper axial section can, for example, be arranged on a water inflow side of the adapter sleeve. The lower axial section can be arranged on a water outflow side of the adapter sleeve.

[0011] In one embodiment of the invention, the retaining projection can be designed as a collar. This allows it to be secured to the fitting mouthpiece at more than one location. It is particularly advantageous if this collar is designed to be circumferential to ensure uniform support.

[0012] In this case, it can be provided that the collar is continuously circumferential in order to ensure that the adapter sleeve can rest against the fitting mouthpiece at any point of its circumference.

[0013] In one embodiment of the invention, the fastening means can be provided with an internal thread. This enables the attachment of a functional cartridge with an external thread. It can be particularly advantageous if the internal thread is conical. This enables easy demolding, for example, during injection-molded production of the adapter.

[0014] In one embodiment of the invention, it can be provided that the fastening means has a slotted link. This enables the simple formation of a bayonet closure. In this case, a functional cartridge can be held which has a corresponding guide projection, for example in the form of a sliding block. In one embodiment of the invention, it can be provided that the fastening means has a locking element. This enables the simple formation of a snap connection. Thus, for example, a functional cartridge which has a corresponding locking element receptacle is secure.

[0015] It is particularly advantageous if the locking element is formed on a spring tongue. This allows for a particularly simple and minimally resistant insertion of the cartridge.

[0016] In one embodiment of the invention, it can be provided that the fastening means is designed to hold, for example, an inserted functional cartridge, in at least two spaced-apart circumferential sections. This makes it possible to even out the applied holding force.

[0017] In one embodiment of the invention, a contact surface for a sealing ring can be formed on the upper axial section. This ensures a tight seal between the adapter sleeve and a fitting. A separate seal between the fitting mouthpiece and the adapter sleeve is thus unnecessary.

[0018] For example, the contact surface can be formed on the aforementioned retaining projection. For this purpose, it is advantageous if this retaining projection is designed to be uninterrupted and circumferential.

[0019] In this case, it can be provided that the contact surface is axially oriented. This allows the use of inexpensive sealing rings with a rectangular cross-section. In one embodiment of the invention, it can be provided that an outer side beyond the retaining projection is cylindrical. This enables a flat contact with the inner side of a fitting mouthpiece. This can be used, for example, to increase the holding force on the fastening means.

[0020] In one embodiment of the invention, a receptacle for a sanitary functional cartridge can be provided on the inside. Preferably, the functional cartridge can be inserted through an axial end of the adapter sleeve, which is arranged by the retaining projection.

[0021] In the embodiment of the invention, it can be provided that some inner side, in particular an inner side defining the aforementioned function, forms an inwardly directed sealing surface. This, if possible, forms a seal between an inserted functional cartridge and the adapter sleeve.

[0022] For example, it can be provided that the sealing surface is formed on an axial end of the adapter sleeve facing away from the retaining projection. Thus, the inner diameter of the adapter sleeve can be larger in the sealing surface area than in the fastening element area. This can be advantageous if the fastening element has an internal thread, as it can then prevent a functional cartridge being inserted from colliding with the sealing surface.

[0023] Alternatively or additionally, the sealing surface of the fastening element can be arranged in a mounting direction of the functional cartridge. This also provides a way to prevent damage to the sealing surface when inserting a counter-fastening element on the functional cartridge into the aforementioned receptacle.

[0024] A preferred application of the invention provides a sanitary installation arrangement with a type of adapter sleeve according to the invention, in particular as described above and / or according to one of the claims directed to an adapter sleeve, and a sanitary functional cartridge, wherein the functional cartridge has a counter-fastening means corresponding to the fastening means. Thus, an adaptation of a fitting mouthpiece to a specific counter-fastening means on the functional cartridge can be achieved in a simple manner.

[0025] For example, it can be provided that, during use, the functional cartridge is arranged in a receptacle formed on the inside of an adapter sleeve, for example the one already mentioned. Preferably, the functional cartridge can be inserted into the adapter sleeve counter to the flow direction of the adapter sleeve. The adapter sleeve, in turn, can be inserted into the outlet nozzle in the flow direction due to its retaining projection.

[0026] In one embodiment of the invention, the counter-fastening means can have an external thread. This is advantageous in that fastening to an internal thread is easy to produce. Preferably, the external thread has a conical shape, so that the functional cartridge can be fastened to a conical internal thread.

[0027] Alternatively or additionally, the counter-fastening means may have a guide projection. Thus, a slotted guide on the adapter sleeve can be used to fasten the functional cartridge. In one embodiment of the invention, the counter-fastening means may have a locking element receptacle. This requires that the functional cartridge can be easily fastened to a locking element, which engages in the locking element receptacle in the position of use.

[0028] In one embodiment of the invention, it can be provided that the functional cartridge can be inserted into the adapter sleeve. Thus, a fastening means in the adapter sleeve can be used for fastening. This fastening means can be used, for example, to fasten the functional cartridge. It is particularly advantageous if this fastening is designed to be detachable so that the fusion cartridge can be removed again.

[0029] An example of such a detachable connection is a screw connection or a bayonet connection.

[0030] An inventive use of the adapter sleeve, in particular an adapter sleeve as described above and / or below, for fastening a sanitary functional cartridge to a fitting mouthpiece provides that the functional cartridge has a counter-fastening means that interacts with the fastening means. By interposing an adapter sleeve between the functional cartridge and the fitting mouthpiece according to the invention, the design freedom of the functional cartridge can be improved or expanded.

[0031] In one embodiment of the invention, the mouthpiece supports the adapter sleeve on the retaining projection. This prevents a connection between the adapter sleeve and the mouthpiece from being created that is either underloaded or self-loosening. A particularly simple embodiment can be provided for the fitting mouthpiece to support the adapter sleeve with a shoulder.

[0032] According to one embodiment of the invention, the adapter sleeve can define a space between the functional cartridge and the fitting mouthpiece at least in a circumferential section, preferably over its entire circumference. This can be used to increase the dimensional stability of the adapter sleeve, so that the holding force of the fastening of the functional cartridge to the adapter sleeve can be increased.

[0033] In one embodiment of the use, it can be provided that the functional cartridge is arranged in a receptacle formed on the inside of the adapter sleeve. This allows for easy actuation or activation of the fastening. For example, this arrangement can be achieved by inserting the functional cartridge through an axial end of the adapter sleeve facing away from the retaining projection. This enables, for example, the formation of parts of the functional cartridge that, in the position of use, extend beyond the fitting mouthpiece in the jet direction or axial direction.

[0034] The invention will now be described in more detail with reference to exemplary embodiments, but is not limited to these exemplary embodiments. Further exemplary embodiments of the invention result from the combination of the features of one or more claims with one another and / or with one or more features of the exemplary embodiments.
