Abstract

For the cartridge adapter (9) it is therefore proposed to use at least one spring element (16) as a pull-out protection on a sanitary fitting (1), wherein alternatively or additionally the hose receptacles (21) describe a non-equilateral triangle.

Description

[0001] The invention relates to a cartridge adapter.

[0002] Cartridge adapters are well-known in practice and are used to fluidically connect a valve cartridge to hoses. For this purpose, the known hose receptacles have a contact surface against which the valve cartridge can rest tightly. Connection openings corresponding to the inlets and outlets of the valve cartridge are formed in the contact surface, each of which is fluidically connected to a hose receptacle.

[0003] Valve cartridges often provide a mixing function for mixing hot and cold water, as well as a flow rate control function. The corresponding cartridge adapters therefore have three hose receptacles, for example, for hot and cold water hoses subjected to mains pressure and a mixed water hose designed for low pressure.

[0004] Such valve cartridges can be designed, for example, as single-lever mixing cartridges or as rotary-push valves.

[0005] The invention is based on the object of improving the performance characteristics of a cartridge adapter.

[0006] To achieve this object, the features of claim 1 are provided according to the invention. In particular, to achieve the stated object, the invention proposes that a cartridge adapter have at least one spring element for holding the cartridge adapter to a sanitary fitting in a force-fitting and / or positive-locking manner. Thus, the cartridge adapter can be easily secured to a correspondingly designed sanitary fitting in one assembly step, in particular against accidental removal, until it is fixed by an inserted valve cartridge. Thus, for example, a cartridge adapter inserted vertically from below can be easily secured against accidental removal.

[0007] In one embodiment of the invention, the spring element can be molded onto the cartridge adapter. This eliminates the need for small parts and separate assembly steps for these small parts.

[0008] In one embodiment of the invention, the spring element can be provided as a locking element. This allows for automatic locking and / or positive locking.

[0009] In one embodiment of the invention, two spring elements can be provided that preferably act against each other. Thus, the spring elements can support each other in their securing position.

[0010] In one embodiment of the invention, it can be provided that the at least one spring element extends transversely to an insertion direction of the cartridge adapter. This allows for positive and / or non-positive locking against a pull-out force directed counter to the insertion direction, even when the valve cartridge is removed.

[0011] In one embodiment of the invention, the spring element can interact with a designated receptacle in the sanitary fitting. This makes a positive fit easy to achieve.

[0012] In one embodiment of the invention, the cartridge adapter can be made of plastic. This allows complex shapes to be manufactured easily and / or cost-effectively.

[0013] It is particularly advantageous if the cartridge adapter is made of glass-fiber-reinforced plastic. This allows for increased strength and, in particular, increased stiffness of the spring elements.

[0014] In one embodiment of the invention, the cartridge adapter can be coupled to a valve cartridge. This allows for a fluidic connection of a valve cartridge to be achieved easily and reliably, particularly by a flat contact surface of a connection side of the valve cartridge against the contact surface of the cartridge adapter.

[0015] In one embodiment of the invention, the cartridge adapter can be provided with a support surface on the sanitary fitting. This makes it easy to support the pressure exerted by the valve cartridge on the cartridge adapter. This can facilitate a tight fluid connection between the valve cartridge and the cartridge adapter.

[0016] In one embodiment of the invention, it can be provided that the at least one spring element extends along a support surface of the cartridge adapter, for example, the one already mentioned. This allows for easy release of the at least one spring element from outside a cartridge receptacle.

[0017] In one embodiment of the invention, it can be provided that the at least one spring element rebounds transversely to a contact surface of the cartridge adapter, for example, the one already mentioned. This allows for easy release of the at least one spring element from within a cartridge receptacle.

[0018] It is particularly advantageous if the cartridge adapter has at least one pin receptacle for the valve cartridge. This can provide a rotation lock for the valve cartridge and secure the cartridge adapter with a pin on the valve cartridge.

[0019] To achieve the stated object, the invention alternatively or additionally provides the features of the second independent claim directed to a cartridge adapter. In particular, in a cartridge adapter for a sanitary fitting with at least one hose receptacle, in particular the cartridge adapter already described, it is proposed that the cartridge adapter rests on a sanitary fitting with a support surface in an installed position, and that at least part of the hose receptacle is located on the cartridge side with respect to the support surface. Thus, any overhang of the cartridge receptacle on the housing of the sanitary fitting can be shortened.

[0020] In one embodiment of the invention, the hose receptacle can be located in a rearward extension of the support surface. This saves lateral installation space in a main pipe of the sanitary fitting.

[0021] In one embodiment of the invention, the support surface and the hose receptacle can be formed in a common installation space. This enables a compact design of the cartridge adapter.

[0022] In one embodiment of the invention, the cartridge adapter can be connected to a valve cartridge in the installed position by means of a force-locking and / or positive locking mechanism. This allows the cartridge adapter to be easily secured in the sanitary fitting by the valve cartridge. Additional fixing devices are unnecessary.

[0023] To achieve the stated object, the invention alternatively or additionally provides the features of the third independent claim directed to a cartridge adapter. In particular, in a cartridge adapter, particularly as described above, with at least three hose receptacles, it is proposed that at least one hose receptacle remote from the cartridge maintains different distances from at least two hose receptacles on the cartridge side. This makes it easy to create a free space in a main pipe of a sanitary fitting, which can be used, for example, for a pull-out hose.

[0024] In one embodiment of the invention, the hose receptacles can be offset from one another and / or asymmetrically designed. Thus, a clear profile of a main pipe, preferably designed with a round cross-section, can be used for additional functions, for example, for accommodating an extension hose.

[0025] In one embodiment of the invention, it can be provided that the connection of the hose receptacle remote from the cartridge is formed on the cartridge adapter above the connections of the hose receptacles on the cartridge side. Thus, intersections of the fluid lines can be avoided.

[0026] To achieve the stated object, the invention alternatively or additionally provides the features of the fourth independent claim directed to a cartridge adapter. In particular, in a cartridge adapter, particularly as described above, with at least one hose receptacle, it is proposed that a rotation-locking element for a received hose nipple be formed on the hose receptacle.

[0027] In one embodiment of the invention, it can be provided that the anti-rotation element interacts with an anti-rotation element of the hose nipple.

[0028] In one embodiment of the invention, it can be provided that the rotation-locking element is connected in one piece to the hose receptacle and / or is formed on the hose receptacle.

[0029] In one embodiment of the invention, it can be provided that a hose receptacle, for example the one already mentioned, is aligned at an angle to a contact surface, for example the one already mentioned, for a valve cartridge.

[0030] A preferred application of the invention provides a cartridge adapter set with a cartridge adapter according to the invention, for example as described above or claimed below, and at least one hose nipple with an anti-rotation element.

[0031] A preferred use of a cartridge adapter according to the invention, for example as described above or claimed below, can provide for the cartridge adapter to be secured, preferably in a form-fitting manner, by the at least one spring element before the cartridge adapter is fixed by an inserted valve cartridge. This allows for multi-stage assembly, in which, for example, the cartridge adapter, preferably with pre-installed hoses, is inserted into the sanitary fitting in a preparatory step, and the valve cartridge is inserted in an assembly step.

[0032] A preferred application of the invention provides a sanitary fitting with a housing, a valve cartridge and a cartridge adapter, in particular a cartridge adapter according to the invention, for example as described above or claimed below, wherein the valve cartridge is placed on the cartridge adapter in the housing, wherein the cartridge adapter is secured to the housing by at least one spring element and fixed in the housing by the valve cartridge. Thus, a firm fixation can be achieved by a contact force, which simultaneously creates a tight fluidic connection between the valve cartridge and the cartridge adapter. In the installed position, securing the cartridge adapter to the sanitary fitting by the spring element is dispensable. However, if the valve cartridge is removed again, the at least one spring element continues to secure the cartridge adapter.

[0033] Preferably, the at least one spring element is accessible through the main tube or through the cartridge receptacle. This allows the pull-out protection to be released.

[0034] The advantages of the invention can be utilized particularly well if the sanitary fitting is provided with a cartridge holder that protrudes laterally from a main pipe.

[0035] The invention will now be described in more detail using exemplary embodiments, but is not limited to the exemplary embodiments. Further exemplary embodiments arise from combining the features of one or more claims with one another and / or with one or more features of the exemplary embodiments.

[0037] In the following exemplary embodiments, functionally and / or structurally similar or identical components and functional units are designated by the same reference numerals and—to avoid repetition—are not described separately for each exemplary embodiment. The explanations therefore apply accordingly.

[0038] The Figures 1 to 11 are described together below.

[0039] Figure 1 shows part of a sanitary fitting, designated as a whole by 1. The sanitary fitting 1 has a main pipe 2, which is positioned vertically in the use position, for example, on a washbasin. A cartridge holder 3 protrudes laterally from the main pipe 2.

[0040] A valve cartridge 4 is inserted into the cartridge holder 3.

[0041] From below, three hoses 5, namely a hot water hose 6, which is pressurized with mains pressure, a cold water hose 7, which is also pressurized with mains pressure, and a mixed water hose 8, which is designed for low-pressure applications, are inserted into the main pipe 2. The main pipe 2 is thus designed to carry the pipe.

[0042] Figure 2 shows the representation from Figure 1 , whereby the sanitary fitting 1 is shown partially transparent.

[0043] It can be seen that the valve cartridge 4 is fluidically connected to the hoses 5 via a cartridge adapter 9.

[0044] The valve cartridge 4 has a lever 10 which is rotatable about a longitudinal axis of the valve cartridge 4 and pivotable about a pivot axis perpendicular thereto in order to realize - in a manner known per se - a mixing function and a quantity control function.

[0045] Figure 3 shows a view of the connection side 11 of the valve cartridge 4.

[0046] Two pins 12 are designed to secure the valve cartridge 4 in rotation. The position of the pins 12 indicates that the valve cartridge 4 is rotated 45° around its longitudinal axis. This has advantages for the position of the lever 10 in its end positions relative to the sanitary fitting 1.

[0047] The connection openings 13 communicate fluidically via the Figure 3 Cartridge adapter 9 omitted for simplicity.

[0048] The cartridge adapter 9 is inserted from below through the main tube 2 into the cartridge holder 3 and rests with its support surface 14 on a base 15 of the cartridge holder 3.

[0049] In Figure 10 and Figure 11 It can be seen that the cartridge adapter 9 has two spring elements 16 which act against each other and are inserted into a receptacle 17 on the sanitary fitting 1 and there, by locking, secure the cartridge adapter 9 against falling out, in particular under a load of the connected hoses 5.

[0050] The spring elements 16 are integrally formed onto the cartridge adapter 9. The cartridge adapter 9 is made of a glass-fiber-reinforced plastic.

[0051] The spring elements 16 therefore each form a locking element.

[0052] From the Figures 10 and 11It can be seen that the spring elements 16 rebound transversely to the vertically oriented insertion direction 18 of the cartridge adapter 9.

[0053] The cartridge adapter 9 has a contact surface 19 which forms a fluidically tight seal with the connection side 11 when the valve cartridge 4 is pressed against the cartridge adapter 9 and this against the base 15.

[0054] Thus, the cartridge adapter 9 can be coupled to a valve cartridge 4 via its contact surface 19, which is preferably flat.

[0055] Two pin receptacles 20 are formed in the contact surface 19, which receive the pins 12 of the valve cartridge 4. As a result, the cartridge adapter 9 is fixed in the cartridge receptacle 3 by the valve cartridge 4.

[0056] In Figure 10 It can be seen that the spring elements 16 rebound longitudinally, i.e. for example in one plane, of the contact surface 19.

[0057] Since the receptacle 17 is accessible from above in the main pipe 2, the lock of the cartridge adapter 9 can be released again in order to remove the cartridge adapter 9.

[0058] Figure 12 shows a further variant of a cartridge adapter 9 according to the invention.

[0059] The embodiment according to Figure 12 differs from the embodiment according to the Figures 1 to 11 by the fact that the spring elements 16 are mounted laterally. The spring elements 16 continue to deflect transversely to the insertion direction 18 and along the contact surface 19.

[0060] The spring elements 16 are in Figure 12 accessible from below through the main tube 2 and, if necessary, also from the outside through the cartridge holder 3 in order to release the securing of the cartridge adapter 9.

[0061] In use, the spring elements 16 lock into or with corresponding locking receptacles on the sanitary fitting 1.

[0062] Figure 13shows a further embodiment of a cartridge adapter 9 according to the invention.

[0063] The embodiment according to Figure 13 differs from the preceding embodiments in that the spring elements 16 filter into the cartridge holder 3, where they rest in a relaxed position on a part of the sanitary fitting 1.

[0064] Since the pins 12 engage in the pin receptacle 20, the cartridge adapter 9 does not fall out even if the spring elements 16 are bent out of their rest position by the valve cartridge 4.

[0065] The spring elements 16 thus spring out transversely to the insertion direction and transversely, i.e., for example, normally, to the contact surface 19.

[0066] The cartridge adapter 9 has three hose receptacles 21 for connecting the hoses 5.

[0067] In Figure 9It is clearly visible that two of the hose receptacles 21, namely the hose receptacles 21 for the cold water hose 7 and the mixed water hose 8, are arranged in a rearward extension of the contact surface 19 and the support surface 14, respectively.

[0068] Here, the hose receptacles 21 and the support surface 14 are arranged in a common installation space 22 in the main pipe 2.

[0069] Figure 9 shows that the hose receptacles 21 can be divided into one hose receptacle 21 remote from the cartridge and two hose receptacles 21 on the cartridge side. The cartridge-side hose receptacles 21 are arranged above the hose receptacle 21 remote from the cartridge.

[0070] The hose receptacles 21 are offset from one another and arranged asymmetrically, which is expressed by the fact that the hose receptacles 21 remote from the cartridge maintain different distances from the hose receptacles 21 on the cartridge side.

[0071] In Figure 11 It can be seen that the hose receptacles 21 can each be fluidically connected to the valve cartridge 4 via connections 23.

[0072] Here, the connection 23 of the hose receptacle 21 remote from the cartridge is arranged above the connections 23 of the hose receptacle 21 on the cartridge side.

[0073] A rotation-locking element 24 in the form of an axial toothing is formed on the hose receptacle 21 for the mixed water hose 8.

[0074] This acts in the use position with a counter-locking element 25 on the mixed water hose 8 (compare Figure 3 ) together.

[0075] Thus, intentional unscrewing of the screwed-in hoses 5 can be prevented, at least with regard to the mixed water hose 8.

[0076] A similar or different anti-rotation device may be provided on the remaining hoses 6, 7.

[0077] In Fig. 9It can also be seen that at least some of the hose receptacles 21 are located on the cartridge side with respect to the support surface 14. This applies to the two cartridge-side hose receptacles 21.

[0078] These hose receptacles 21 are located in a rearward extension of the support surface 14 and the contact surface 19.

[0079] The support surface 14 and the hose holder 21 are formed in a common installation space.

[0080] From the usage position according to Figure 1 It can be seen that the cartridge holder 3 protrudes laterally from the main pipe 2, into which the hoses 5 are accommodated as lines.

[0081] Correspondingly, the hose receptacle 21 is formed at a right angle to a surface normal of the contact surface 19 or the support surface 14.

[0082] In the cartridge adapter 9, it is thus proposed to use at least one spring element 16 as a pull-out protection on a sanitary fitting 1, wherein alternatively or additionally the hose receptacles 21 describe a non-equilateral triangle. List of reference symbols
