Description

The present invention relates to a sanitary fitting, at least comprising a housing and a cartridge mounted in the housing.

In principle, it is known that in housings of sanitary fittings, a plurality of different electrical and / or mechanical components can be accommodated, such as. Valve devices and in particular also the so-called mixing valve, which is designed as a cartridge. In addition, it is known that such housing can be manufactured with different materials, for example. From cast iron, sheet metal or plastic.

With the aim of easy installation and low-cost production, efforts are being made to make the integration of the components in the housing as easy as possible to handle. Next, the design should be provided as easily as possible and with cheap materials. In particular, a complex reworking of the individual components, in particular of the housing, should be avoided prior to assembly of the components. Nevertheless, it should be noted that the integration of the components in the housing requires a precise arrangement of the components to each other despite the smallest possible space. This is particularly true because the tightness against water breakthrough over a long period of time to ensure and / or long-term corrosion is to be avoided, even if the sanitary fitting is exposed to different levels of intense or intense loads.

On this basis, it is an object of the present invention, at least partially solve the problems described with reference to the prior art. In particular, a sanitary fitting is to be proposed, which is easy to manufacture is and during their installation a lesser effort is required. In addition, the lightweight design should be supported here. Next, the goal is pursued, if necessary, easily compensate for manufacturing tolerances occurring during manufacture during assembly and nevertheless to realize a secure composite of the components with each other.

These objects are achieved with a sanitary fitting according to the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed individually in the claims in any technologically meaningful way can be combined and show other embodiments of the invention. The description, in particular in conjunction with the figures, explains the invention and provides additional developments of the invention.

• ein Gehäuse, das eine von einem Kragen umgebende Öffnung sowie einen Innenraum ausbildet,
• ein Befestigungsbauteil, das im Gehäuse benachbart zu dem Kragen anordenbar ist,
• einen Kartuschenhalter, der in dem Innenraum positionierbar ist,
• eine Kartusche, die zumindest teilweise in dem Innenraum positionierbar ist, sowie
• ein Spannmittel, das durch direkten Kontakt zumindest die Kartusche oder den Kartuschenhalter gegen das Befestigungsbauteil verspannen kann.

The sanitary fitting has at least the following components:

• a housing, which forms an opening surrounding by a collar and an interior space,
• a mounting member locatable in the housing adjacent to the collar,
• a cartridge holder which is positionable in the interior,
• a cartridge that is at least partially positionable in the interior, as well as
• a clamping means which can clamp by direct contact at least the cartridge or the cartridge holder against the fastening component.

The housing can be made in one piece or in several parts. The housing may be metallic and / or made with plastic. Such a housing regularly has a base or a housing underside and a housing upper side, wherein the housing can be fastened to a washstand in the region of the floor, for example, and an operating lever can be provided in the region of the housing upper side. The housing may have a substantially barrel-shaped basic structure, wherein a kind of outlet spout may be provided, from which the water then emerges. Alternatively, the housing but also cylindrical, square, oval have a polygon or other basic shapes. The housing also has a collar (single and / or circumferential) surrounding an opening of the housing. In particular, the collar can form a termination of the housing in the region of the upper side of the housing. The opening is preferably round. The collar is formed in particular in the direction of a central axis of the housing inwardly. Interior adjacent to the opening then an interior space is formed. The interior of the housing is in particular so large that it can accommodate the components to be fastened therein (in particular at least the fastening component, the cartridge holder, the cartridge and the tensioning means). However, the opening need not be so large that all these components can be inserted therethrough; Often it can also be provided that these components are introduced from the ground into the interior. In this case, the interior between the bottom and the housing top of the housing is designed to extend.

Furthermore, a fastening component is provided, which is positionable in the interior and possibly fully abuts the collar inside. The fastening component is in particular a separate component, which bears against an inner surface of the housing with its outer surface, but is not connected to it so that the fastening component no longer perform a relative movement toward the housing can. The installation of the fastening component can be done from the ground. But it is also possible that the fastening member is deformable for assembly purposes, can be inserted through the smaller opening through the collar and then widens, so that the outer, upper end side of the annular-shaped fastening component can be brought to the inside of the collar to the plant or already fixed in this stop position. It is preferred that the fastening component is formed with a different material than the housing.

Furthermore, a cartridge holder is provided, which can be positioned in the interior. Consequently, the cartridge holder can be directly / indirectly held, guided or fixed in the housing. The cartridge holder also has the task of receiving the cartridge. This has to be done in particular so that a directed positioning of the cartridge in the housing is possible, in particular that the corresponding connections or sequences for the water and / or the positioning of the actuating lever during assembly can be easily realized. In addition, the cartridge holder can fulfill the function of an adapter, wherein the cartridge holder or a plurality of different cartridge holder can be inserted into the housing and accommodate various embodiments of the cartridge appropriately directed. The cartridge holder is in particular pot-shaped, in which case plastic is preferably used as the material.

Next, the cartridge (together with the cartridge holder) can be positioned in the interior. The cartridge sits for this purpose in particular in suitable recesses of the cartridge holder. It is not mandatory that the cartridge be completely received in the cartridge holder. It may be sufficient that a directed guidance and fixation of the example. Lower Part of the cartridge is made possible in the cartridge holder. It may be preferred that the cartridge optionally has a shoulder or a (radially encircling) stop edge, which can also be brought into contact with the clamping means, so that the clamping means simultaneously pressed or fixed in position the cartridge in the cartridge holder.

In addition, a tensioning means is provided, which can preferably be mounted over the opening of the housing. In particular, it cooperates with the fastening component such that a clamping force can be built up between the fastening component on the one hand and the cartridge and / or the cartridge holder on the other hand. For this purpose, it is preferably provided that first the components fastening component, cartridge holder and cartridge are positioned in the housing and then the tensioning means is brought into operative engagement with the fastening component through the opening. During assembly, the clamping means is preferably moved axially into the interior, wherein the clamping means then comes into contact with the cartridge holder and / or the cartridge. Further displacement of the clamping means in the interior now brings a force on the cartridge holder and / or the cartridge, so that they are pressed into the housing or its abutment. Once the predetermined position is reached, the clamping means is locked by means of the fastening component, so that an independent backward movement of the clamping means is prevented from the housing out. Thus, it is supported in the mounted state on the one hand via the fastening member against the collar of the housing and on the other hand directly on the cartridge and / or the cartridge holder. This simple mounting aid ensures in particular to compensate for axial manufacturing tolerances within the housing.

It is considered to be particularly advantageous that the tensioning means has an inner guide sleeve for the cartridge and an outer form engagement with the fastening component. The clamping means is very particularly preferably plate-like, in particular as a (radial) disc, wherein on one side a kind of (axial) tubular connection piece is formed. This tubular nozzle together with the plate forms inside a guide sleeve for the cartridge. In other words, that means that the inner surface of this guide sleeve substantially comprises an outer diameter of the cartridge, where the clamping means is to enclose the cartridge. In particular, in the region of the plate, a structure is provided on the outside, which can cooperate with a corresponding structure of the fastening component and is additionally lockable. For this purpose, in particular mold elements are provided which realize a (releasable) mold engagement of both components. Thus, for example, guide grooves, latching noses or similar form elements can be provided here. In this case, it is also very particularly preferred for the clamping means to form a stop edge opposite the tubular connecting piece, which if necessary cooperates with a corresponding outer contour / stop edge of the cartridge and allows the cartridge to be pushed further into the housing in the axial direction.

According to an advantageous embodiment, the clamping means and the fastening component form a common thread. In this case, it is particularly meant that the clamping means, in particular in the region of the plate, has an external thread, while the, in particular sleeve-shaped or ring-shaped fastening component forms a corresponding internal thread on the inner surface. Thus, then a corresponding clamping force can be realized by the determination of the screw when the clamping device migrates further into the interior of the housing.

Furthermore, it can be provided that the cartridge holder is kept guided in the interior in an insert. The insert may, for example, also represent a (more complex) inner housing, wherein this insert can now be formed with plastic and predetermines the water passage in the interior of the housing, especially in the event that the housing is formed with metal. It is possible that this use by means of the fastening component and / or the clamping means in the assembly of the clamping means by direct / indirect contact also braced in the housing or is pressed there.

In addition, it can be provided that the housing has a bottom stop in the interior, which forms an abutment for the cartridge holder. In other words, in particular, that the cartridge holder (indirectly / directly) on the one hand against the collar and on the other hand braced against the bottom stop, so that here introduced by means of the clamping force on the one hand in the collar (first abutment) and on the other hand at the bottom stop (second Abutment) is passed into the housing. In principle, it would be possible for the cartridge holder, for example, to cooperate with the bottom stop as an abutment via an insert.

In addition, it is considered advantageous that the housing is formed with half shells. For this case, the individual components in the interior of the housing can first be pre-positioned, then the half-shells are joined to each other, in which case only the clamping means must be introduced through the opening in the interior for final assembly. The advantageous tension by means of the clamping means also leads to manufacturing tolerances in the half shells can be easily compensated. Alternatively, the housing can be preassembled with the insert and the fastening component initially and the cartridge used later, for example, after a galvanic treatment.

The attachment of the cartridge is therefore very particularly preferably by a single, designed in the manner of a central disk clamping means. This braces the cartridge together with the cartridge holder in a fastening element designed as a threaded ring between two corresponding abutments in the housing. By tightening this central disk, the components cartridge holder and mounting member are clamped together axially, height tolerances can be compensated and at the same time the cartridge is pressed. In this case, for example, no reworking of the housing after the gluing of the half-shells of the housing longer necessary. In addition, a releasable compression and thus a simple assembly and disassembly of the cartridge assembly is possible without the need for additional fasteners. Furthermore, it is possible that the fastening component is provided with a material which has a corresponding strength (increased compared to other components if necessary).

Fig. 3

a detail of a variant of the sanitary fitting in the region of the clamping device.

Fig. 1 shows a sanitary fitting 1, which is mounted by means of suitable brackets 17 to a washstand 18. The sanitary fitting 1 has a housing 2, which is positioned above the wash basin 18. In it, in an inner space 5, a cartridge holder 7 is provided, in which a cartridge 8 is positioned. Through the washstand 18 extends in the direction of an axis 22, the holder 17 and the water inlet 19. While the holder 17 is anchored in the region of the bottom 27 of the housing 1, the water inlet 19 penetrates the interior 5 through to the cartridge holder 7. There are Provided connections to the cartridge 8, so that here a water treatment can be done (especially hot / cold regulation). Again, starting from the cartridge 8 and the cartridge holder 7 then extends a water outlet 20, which is designed here like a tube. On the right side of the housing 2, a type of snout is formed, which receives the jet former to the outlet of the water. Above, in the area of the housing upper side 26 of the housing 1, also the operating lever 16 can be seen, with which an operator of the sanitary fitting 1 can regulate the water flow or the water temperature. In the area of the housing upper side 26 of the housing 2, a fastening component 6 and a tensioning means 9 are now also indicated, with which a tensioning of the cartridge and / or cartridge holder against the fastening component 6 is made possible.

Fig. 2 shows an embodiment of a sanitary fitting 1, wherein here in the interior 5 of the housing 2 formed with half-shells 15 in the region of the bottom 27, a bottom stop 14 is formed. The bottom stop 14 may be part of the housing 2 and / or a part of the insert 13, the here also for training the watercourse 20 is provided on the inside of the housing 2. The housing 2 has at the top in the region of the housing top 26 a final, inwardly directed collar 3, which defines a circular opening 4. Internally adjacent and supported against the collar 3, a separate fastening member 6 is positioned in the manner of a ring. This is in particular designed so that it can not be inserted axially through the opening 4. Below or frontally opposite wall sections of the insert 13 are then positioned. The insert 13 itself is supported against the bottom stop 14. The design of the insert 13 is so preferred that the fastening member 6 can be used with sufficient clearance and taking into account the potential manufacturing tolerances in the space between insert 13 and collar 3. Within the housing 2 and in particular also within the insert 13, a cartridge holder 7 is now received. The cartridge holder 7 can also form guides or connections for the water inlet 19 towards the bottom. Opposite or aligned towards the top of the housing, a receptacle for the cartridge 8 is provided, which is already integrated here. The cartridge 8 further has, in particular approximately in the region of an axial end face of the cartridge holder 7, a stop edge 28 which extends in the direction of the radius 23 and is designed to enclose at least partially in the direction of the circumference 24.

For mounting, the clamping means 9 is now placed over the outside of the opening 4 of the housing 2 protruding part of the cartridge 8 and brought into operative engagement with the fastening member 6 behind the collar 3. In this case, elements are provided here, which form a mold engagement 11 between clamping means 9 and fastening component 6. During assembly, therefore, the clamping means 9 is moved in the direction of the axis 22, wherein by a direct contact of the clamping means 9 with the cartridge 8 and / or the cartridge holder 7 a Clamping force is generated so that height tolerances between the components collar 3, fastening member 6 and cartridge 8 / cartridge holder 7 can be compensated. This results in a tension of said components in the interior 5 of the housing. 2

Fig. 3 shows a detail for a variant of the attachment or clamping, for example in the area "III" in Fig. 2 , Here it can be seen that the clamping means 9 on the one hand forms an inner guide sleeve 10 for the cartridge 8 and also externally forms a common thread 12 with the fastening component 6. If, therefore, the fastening component 6 is twisted during assembly into the thread, a tensioning of the cartridge holder 7 takes place here against the collar 3 of the housing 2. At the same time, the cartridge 8 can be clamped in the cartridge holder 7, in particular by the clamping means 9 resting on a stop edge 28 of the cartridge 8 acts axially. The bracing of the components should preferably take place only in the axial direction, in particular in order not to damage seals 21 located between the components.

Thus, the invention solves the problems initially posed and in particular indicates a simple to install and inexpensive sanitary fitting.

As a precaution, it should be noted that the combinations of technical features shown in the figures are not generally mandatory. Thus, technical features of one figure can be combined with other technical features of another figure and / or the general description. Something else should only apply if the combination of features has been explicitly stated here and / or the person skilled in the art recognizes that otherwise the basic function of the sanitary fitting (provision of water) can no longer be met.
