Abstract

A water fitting for dispensing water in a sanitary device, comprising a fitting member which is placed on this sanitary device, and a device which is arranged on the fitting member for actuating a cartridge, the cartridge containing a cold and a hot water supply flow, devices for opening and closing the supply flows and for limiting and mixing the water streams and a mixed water outlet.

Description

The invention relates to a water fitting for dispensing water in a sanitary device, comprising a fitting member which is placed on this sanitary device, and a device which is arranged on the fitting member for actuating a cartridge, the cartridge containing a cold and a hot water supply flow, devices for opening and closing the supply flows and for limiting and mixing the water streams and a mixed water outlet.
Conventional single-lever water fittings as arranged on sanitary devices, in particular on wash stands, bidets or bathtubs, contain a so-called cartridge in which the cold water stream and hot water stream supplied to the fitting are released or blocked for discharge into these sanitary devices and mixed with each other. Because the cartridges are installed in these fittings, these fittings have a diameter which is predetermined by these cartridges and, depending on the size of the cartridge, the diameter cannot fall below that value. These fittings are therefore bulky.
In recent years there has been a trend towards converting the once functionally fitted bathroom into a so-called wellness zone, the design of the objects becoming increasingly significant. When configuring the fittings, however, designers are constrained for the reason set out above.
An object of the invention is therefore to configure a water fitting in such a manner that the cartridge does not impede the construction of the fitting member of the water fitting.
This object is achieved with the characterising features of claim 1. The dependent claims relate to advantageous configurations of the invention.
According to the invention, the cartridge and the fitting member of the water fitting are spatially separated from each other. The cartridge and the device for actuating the cartridge on the fitting member can be mechanically connected to each other or an electrically operated actuation system is provided, for example, by means of motors. The fitting member is conventionally arranged on the sanitary device, for example, on a wash stand, a bidet or a bathtub, whilst the cartridge is arranged underneath, separated therefrom by the sanitary device.
This arrangement allows the designer a free hand in the configuration of the fitting member, whilst the cartridge is protected from influx of water from outside and from cleaning agents, which reduces wear and increases the service-life. Owing to this protection, a cartridge can be readily changed. With conventional fittings, owing to accumulations of scale and corrosion of threads and seals, it is often no longer possible to change it, so that the entire fitting must be replaced.
The cartridge is a conventional cartridge, as fitted as standard in water fittings. It is advantageous that it does not have to be modified for use outside the water fitting. It therefore also affords the possibility, depending on the construction type, of determining the through-flow quantity of water, the temperature range of the mixed water and the limit values of the temperatures of the mixed water.
Owing to the fact that the device for actuating the cartridge on the fitting member is no longer directly connected to the adjustment lever of the cartridge, it is mechanically connected to the adjustment lever of the cartridge by means of a coupling device. This coupling device allows the conventional tilting and pivoting movements or travel movements of the device for actuating the cartridge to be transmitted to the cartridge in such a manner that the same actuation results are obtained as if the device for actuating the cartridge were directly connected to the adjustment lever of the cartridge.
In the case of electromotive actuation of a cartridge, there may be connected to the device for actuating a cartridge, devices for controlling the rotation direction and the speed of the respective motor which is provided for opening and closing the supply flows and the mixed water outlet and for mixing the water streams and for controlling the quantity of water discharged.
Various configurations are possible for the mechanical coupling device. Whilst the pivoting movements of the device for actuating the cartridge can still be transmitted directly to the adjustment lever of the cartridge in order to adjust the water mixing temperature, an upward or downward movement of the mechanical connection between the device for actuating the cartridge on the fitting member and the adjustment lever of the cartridge must now be converted into a pivoting movement for opening or closing the cold and hot water supply flows. This can be carried out, for example, by means of a gear arrangement comprising rods, an inclined path guide or a flexible shaft as will be explained in greater detail with reference to embodiments.
The cartridge is accommodated in a housing, which encloses the cartridge and optionally also the coupling device and protects them from external influences. The housing further comprises the connections for the cold and the hot water supply flow and for the mixed water outlet of the cartridge. It is also conceivable for only the cartridge to be surrounded by a housing and for the coupling device to be outside the housing and optionally to be protected by a separate housing.
The connection of the housing to the fitting member or the sanitary device is carried out by means of a connection portion. This connection portion, which extends above the adjustment lever of the cartridge and away from it in the direction towards the lower side of the sanitary device is configured in such a manner that it can be secured to the sanitary device or to the base of the fitting member which extends through the sanitary device. The connecting portion can also extend through the sanitary device so that the fitting member can be positioned thereon.
The connecting portion is constructed in such a manner that there is a spacing between the sanitary device and cartridge, which allows the device for actuating the cartridge to be connected to the coupling device and allows the mixed water outlet of the cartridge to be connected to the outlet of the fitting member.
The connecting portion may have the appearance, for example, of a U lying flat, one U member carrying the cartridge with the coupling device and the other member being connected to the sanitary device or to the fitting member. The housing of the cartridge is connected to the member of the connection portion. Another example of a connecting portion is a pipe which provides openings which are correspondingly large for access to the connection location of the coupling device and the device for actuating the cartridge and for connecting the mixed water outlet of the cartridge to be connected to the supply to the outlet of the fitting member. The connecting portion is screwed, with its upper end, to the base of the fitting member which extends through the sanitary device and which is therefore fixed to the sanitary device. The base carries the housing having the cartridge with the connection portion. If the housing of the cartridge is provided with an outer thread, it can be screwed into the tubular connecting portion which is provided with an inner thread.
If the sanitary device has a closure member for its outlet which can be actuated from the fitting member, the actuation rod which is provided for this purpose can extend through the connecting portion and the housing.

The invention will be explained in greater detail with reference to embodiments. In the drawings:

There is illustrated in FIG. 1 as a sanitary device a wash stand 1 which is provided with the water fitting 2 according to the invention. The fitting member 4 of the water fitting 2 is positioned on the upper side 3 of the wash stand 1. The outlet 5 opens into the basin 6 of the wash stand 1, whilst, as a device for actuating the cartridge, an actuation lever 7 is connected to the cartridge 9 by means of a rod 8. Another rod 10 serves to actuate the closure member 11 in the drain 12 of the basin 6. The rod 10 is connected by means of an articulation 13 to another rod 14 via which the closure member 11 is raised in order to open the drain 12 and lowered to close it, if the protrusion 15 at the end of the rod 10 protruding beyond the wash stand 1 is pressed or pulled, as indicated with the double-headed arrow 16. The drain 12 is opened in the illustration.
The cartridge 9 is arranged according to the invention on the lower side 17 of the wash stand 1, separated from the fitting member 4 by the wash stand 1. The cartridge 9 is surrounded by a housing 18 which, in this instance located one behind the other and thereby partially covered, has the connections for the hot water supply flow 19 and the cold water supply flow 20 which are connected to the pipes of the domestic supply system by means of pipes 21 and 22 via the stop taps 23 and 24 which are also located one behind the other, respectively. The mixed water outlet 25 of the cartridge 9 is connected to the outlet 5 of the fitting member 4 by means of a pipe 26.
The housing 18 in the present embodiment surrounds the coupling device 27 which is therefore not visible but will be described below. The coupling device 27 converts the upward and downward movement of the rod 8 which is connected to the actuation lever 7 into the tilting movement of the adjustment lever of the cartridge 9. From the coupling device 27 there protrudes from the housing 18 only the connector 28 which is connected by means of a connection 29 to the rod 8 with which the actuation lever 7 engages.
The actuation lever 7 as a device for actuating the cartridge is secured for the tilting movement, as indicated by the double-headed arrow 30, in an articulation 31 to a terminal portion 32 which terminates the pipe 33 in which the rod 8 is guided in order to actuate the cartridge 9. FIG. 1 illustrates the water fitting 2 in the closure position. If the actuation lever 7 is raised, in the upward direction of the arrow 30, the end 34 of the rod 8 is carried in the guiding slot 35 in the actuation lever 7 and the rod 8 is pulled upwards, whereby the adjustment lever of the cartridge is pivoted and the supply flows 19 and/or 20 are opened, so that water flows from the outlet 5. If the actuation lever 7 is lowered, the adjustment lever of the cartridge is pivoted back into the closure position and the supply flows are closed. The upward and downward movement of the rod 8 is indicated by the double-headed arrow 36. If the actuation lever 7 is pivoted with the terminal portion 32, which is rotatably supported on the pipe 33, as indicated by the double-headed arrow 37, the adjustment lever of the cartridge is also pivoted and the cold and hot water streams are accordingly mixed together in the cartridge 9 so that water with the mixing temperature corresponding to the position flows from the outlet 5.
The housing 18 which surrounds the cartridge 9 and the coupling device 27 is connected, by means of a connecting portion 38, to the fitting member 4 on the wash stand 1 and extends therethrough. It is tubular and screwed to the fitting member 4 in a manner not illustrated in greater detail in this case. The connecting portion 38 has correspondingly large openings so that the connector 28 of the coupling device 27 can be connected to the rod 8 by means of a connection 29 according to the length of the rod 8 of the actuation lever 7. The connection of the pipe 26 to the fitting member 4 is also accessible.
FIG. 2 illustrates an embodiment of a coupling device 27 by means of which the upward and downward movement of the rod 8 which is connected to the actuation lever 7 is converted into the tilting movement of the adjustment lever of the cartridge 9. The features which correspond to those of FIG. 1 have the same reference numerals. The fitting member 4 of the water fitting 2 which is arranged at the upper side 3 of the wash stand 1 extends with a base 39 through the wash stand 1 at its lower side 17. The rod 8 for actuating the cartridge 9 extends through the base 39 and the supply pipe 40 extends to the outlet 5. To the supply pipe 40 there is connected the pipe 26 which leads to the mixed water outlet 25 of the cartridge. The base 39 carries at its end an outer thread 41. The fitting member 4 is secured to the wash stand 1 with a nut 42 which is screwed thereon. Between the nut 42 and wash stand 1, a member 43 of the U-shaped connecting portion 38 is clamped. A seal 44, for example of rubber, which is located between the member 43 and the wash stand 1 ensures sealing and reduction of tension. By means of auxiliary positioning means which are not illustrated in this instance, for example a tongue which extends into the opening of the member which receives the base 39 and a corresponding groove in the base, it is possible to ensure positionally correct installation and to prevent torsion of the cartridge during operation.
The fitting member 4, instead of using a screw-type connection via the outer thread 41, can also be connected to the base 39 of the fitting member 4 by means of a pressure plate which is pushed via at least one threaded pin inserted into the base and which is pressed against the lower side 17 of the wash stand 1 by means of a nut which is screwed onto the threaded pin. This embodiment is not illustrated in this instance.
The lower member 45 of the connecting portion 38 carries the housing 18 with the cartridge 9 located therein. The base 46 of the housing 18 is configured in the same manner as the base inside a conventional fitting. The supply and outlet flows of the cartridge 9, when being secured to the member 45, are pressed with a screw connection 47 against the openings of the hot water supply flow 19 and the cold water supply flow 20 and the mixed water outlet 25 and are sealed by means of O-rings which are not illustrated in this instance. A rubber seal 48 located between the cartridge 9 and the member 45 ensures the adjustment of the correct application pressure. Owing to the screw connection 47, it is possible to install the cartridge 9 in the correct position with respect to the coupling device 27.
The present construction affords the advantage that the cartridge can be changed, without the connecting portion 38 having to be released from the fitting member 4 for this purpose. A release of the fitting member 4 from the wash stand 1 is in turn thereby avoided.
The housing of the cartridge 9 is partially cut away. It is possible to see the adjustment lever 49 which is supported in a socket 51 with its journal 50. During the tilting movement about the rotation point 52 in the socket 51, there is moved by the carrier pin 53 the covering plate 54 which in turn is connected to the control plate which is located therebelow for opening and closing the supply flows and for mixing the water streams.
As already set out above, the upward and downward movement 36 of the rod 8 which is connected to the actuation lever must be converted into a tilting movement of the adjustment lever 49 indicated by the double-headed arrow 56. The coupling device 27 is provided for this purpose. Into the adjustment lever 49 there is screwed in an end-face thread 57 another lever 58 which is cranked and which carries at its end a roller 59. Using the thread 57, it is possible to adjust the angle and spacing with respect to the rod 8 within the coupling device 27 in a positionally precise manner. After adjustment to the length of the rod 8, a torsion-prevention means 60, in this instance a screw, prevents possible displacement.
The roller 59 travels in a circular guiding path 61 of a lever 62, the path being rotated towards the right. The portion having the guiding path 61 may be fork-like and may enclose the lever 58 at both sides, which allows a uniform transmission of the movements during pivoting movements. The lever 62 is connected to the rod 8. The rod 8 is inserted in a tubular portion 63 of the lever 62 and connected thereto by means of a split pin 29. There are provided in the rod 8 and in the tubular portion 63 of the lever 62 a plurality of holes 64 which are arranged one above the other for the connection 29 so that, when they overlap, it is possible to connect the rod 8 to the lever 62 of the coupling device 27 in an operationally correct manner with adaptation to the length of the rod 8.
If the actuation lever 7 on the fitting member 4 is lifted from the closure position illustrated in the direction of the arrow 30 (FIG. 1), the rod 8 which is connected thereto is lifted in the direction of the arrow 55 and the lever 62 is pulled upwards. The roller 59 is thereby forced to follow the guiding path 61, the roller being pivoted on a circular path 65 and the adjustment lever 49, also on a circular path 56, being pivoted to the left, whereby, depending on the horizontal pivot position of the actuation lever 7, at least one of the water supply flows 19, 20 is opened.
In the current embodiment, the coupling device 27 is surrounded by a cover 66 which is arranged separately from the housing 18 and which is placed on the member 45 of the connecting portion 38. The lever 62 is directed out of the opening 67 so that the rod 8 can be connected. Owing to the cover 66, the coupling device 27 is protected from external influences such as splashes of water or mechanical effects.
The situation of the completely open position of the adjustment lever 49 is illustrated in FIG. 3. Since the actuation lever 7 has been pivoted into the end position, the adjustment lever 49 of the cartridge 9 is also in its end position. The mixed water outlet 25 of the cartridge is completely opened. In accordance with the illustration in the Figure, the adjustment lever 49 is located in the central position of the possible pivot movements, indicated by the double-headed arrow 68 so that the supply flows 19 and 20 are both opened to the same extent. The mixing temperature of the discharged water can be adjusted by the horizontal pivot movements of the actuation lever 7.
In the embodiment according to FIG. 4, another form of coupling device 127 is set out. Features which correspond to the previous embodiment are given the same reference numerals. There is also screwed into the adjustment lever 49 a cranked lever 69 which contains a slot-like guiding path 70. The angle 71 about which the lever 69 is bent corresponds to the angle 72 about which the adjustment lever 49 is pivoted into the completely open position. In the slot, the guide path 70, there runs a roller 73 which is fitted to the end of a hollow rod 74, which protrudes from the opening 67 of the cover 66. Into this rod 74 there is pushed the rod 8 which is connected to the actuation lever. As in the previous embodiment, the connection between the rod 8 and the rod 74 is carried out by means of a split pin 29 which is inserted into aligned holes 64 in the rods which are pushed one inside the other. The lever 69 may be fork-like and surround the end of the rod 74 at both sides.
If the actuation lever 7 on the fitting member 4 is lifted from the closure position illustrated in the direction of the arrow 30 (FIG. 1), the rod 8 which is connected thereto is lifted in the direction of the arrow 55. This also pulls the hollow rod 74 with the roller 73 upwards. The guide path 70 is thereby forced to follow the roller 59, the lever 69 being pivoted on the circular path of the angle 71, and the adjustment lever 49 pivoting to the left on the circular path of the angle 72 whereby, depending on the horizontal pivot position of the actuation lever 7, at least one of the water supply flows 19, 20 is opened. This situation is illustrated in FIG. 5.
FIGS. 1 to 5 illustrate embodiments in which the actuation of the cartridge is carried out directly in a manual manner. In contrast, it is possible to envisage a driving system using motors wherein one motor is provided for the opening and closing and quantity limitation of discharged water and another motor for the adjustment of the temperature of the mixed water. On the rod 8, which then does not extend as far as the fitting member, a toothed wheel and a toothed rod may be arranged. Via the toothed wheel, a driving toothed wheel is in engagement with the motor which is provided for the adjustment of the mixed water. Via the toothed rod, a driving toothed wheel is in engagement with the motor which is provided for the opening and closing and the quantity limitation of the discharged mixed water. This embodiment is not illustrated.
A completely different solution by means of which the opening, closing and mixing movements of the device for actuating the cartridge on the fitting member are transmitted to the cartridge is illustrated in FIGS. 6 to 8. The features which correspond to those of the previous embodiments are also given the same reference numerals in this instance. The movement transmission is carried out by means of a flexible shaft 75 as a coupling device 227. This is connected on the one hand to the adjustment lever 49 of the cartridge 9 and on the other hand to an actuation handle 76 as a device for actuating the cartridge which is supported pivotably, as indicated by the double-headed arrow 77 in FIG. 7, and movably, as indicated by the double-headed arrow 78 in FIG. 8, in the outlet 5 which also contains the water supply pipe 40. Using a flexible shaft, it is possible also to transmit the opening, closing and mixing movements, even when the actuation handle and the cartridge are arranged offset relative to each other.
FIG. 7, a sectioned illustration perpendicular relative to the viewing plane in FIG. 8, as indicated by the plane of section A-B, illustrates that the flexible shaft 75 is supported in a tubular guide 79 in the outlet 5. The actuation handle 76 can be pivoted in a wedge-like slot 80 in the rear of the outlet 5 in order to actuate the cartridge 9, cf. double-headed arrow 77, and can be moved, cf. double-headed arrow 78. The slot 80 is protected from contamination by water and cleaning agents by means of a cover 81.
The housing 82 which covers the cartridge 9 is more solid than the housing of the previous embodiments so that it can withstand the forces exerted by the flexible shaft 75. The housing 82 is secured to the connecting portion 38 by means of the screw connections 47 which also carry the housing 18 of the cartridge 9. The flexible shaft 75 is guided through a guide pipe 83 to the adjustment lever 49 to which it is secured at the end face by means of a screw connection 57 which is secured with a screw 60.
FIG. 6 illustrates the state in which the adjustment lever 49 is in a central position in the position in which the supply flows 19 and 20 and the mixed water outlet 25 of the cartridge 9 are completely open. To this end, the actuation handle 76 on the outlet 5 was moved in the direction of the arrow 78 to the left, in the longitudinal direction of the outlet 5. The flexible shaft 75, which is pushed through the guide pipe 83 into the housing 82 and, when the cartridge is closed, is completely perpendicular, as indicated with broken lines 84, seeks to become shorter and meets with resistance in the adjustment lever 49. The flexible shaft 75 bulges in the direction of the arrow 85, whereby the adjustment lever 49 is pivoted into the open position. If the actuation handle 76 is pivoted to the left or right, as indicated with the double-headed arrow 77, the flexible shaft 75 rotates in the tubular guide 79. This rotational movement is transmitted to the adjustment lever 49 as a pivot movement for mixing the cold and hot water stream. The guide pipe 83 must be arranged relative to the centre of rotation 52 of the adjustment lever 49 in such a manner that the rotation movements of the flexible shaft 75 which occur when the actuation handle 76 is pivoted in the direction of the double-headed arrow 77 can be transmitted to the adjustment lever 49 in such a manner that it adjusts the desired mixture of the hot and cold water streams by means of its pivoting movement.
FIG. 9 illustrates an embodiment for the configuration of a water fitting in a construction which is kept flat. Features which correspond to the water fitting 2 illustrated in FIG. 1 are given the same reference numerals. As can be seen, owing to the lack of a cartridge in the fitting member 4, a very small structural height is possible. The water fitting 2 is also positioned on a sanitary device 1 in this instance. The fitting member 4 comprises only the outlet 5 and an actuation lever 86 which is securely connected to the connecting rod 8 in order to actuate the cartridge. The opening of the outlet 5 is not illustrated since its configuration is dependent on whether it extends, for example, into a basin, a bathtub or a bidet.
The cartridge, which is not illustrated in this instance, is secured as in FIG. 1 with a connecting portion 29 to the base 39 of the fitting member 4 which extends through the sanitary device 1.
In contrast to the embodiment according to FIG. 1, in this embodiment of the water fitting 2 the actuation lever 86 is not intended to be tilted in order to adjust the quantity of water. Owing to the fixed connection to the connecting rod 8, the actuation lever 86 must be raised in order to open the supply flows and lowered to close them, as indicated by the double-headed arrow 87. This movement is transmitted to the rod 8, as indicated by the double-headed arrow 36. In contrast, the adjustment of the temperature of the mixed water is carried out in the usual manner by pivoting the actuation lever 86 to the right or to the left as indicated by the double-headed arrow 37.
