Description
Miring Valve With A Hand Lever The invention concerns a mixing valve, consisting of a fixture body and a valve cartridge accommodating the valve elements, with a hand lever for operating a valve element which can be moved in two degrees of freedom to determine the mixing ratio and total rate of flow, whereby the hand lever connected with the valve element and pivotable about two axes of rotation arranged at right angles to one another in the valve cartridge is led out laterally from the casing of a lever head housing which is pivoted about the first axis of rotation and in the form of a sleeve.
A mixing valve of this generic type is known from the European patent publication number 0 140 275 B1. In this case, the lever head housing is made in two parts and consists of a casing sleeve and a protective cap. Moreover, a bushing which can be screwed into a receiving bore on the fixture is required to secure and guide the lever head housing.
It is the object of the invention to improve a mixing valve, in particular with respect to a lever head housing.
According to the invention, this object is solved therein that the sleeve adjoins and is guided with a front end in the area of the fixture, whereby clamping and stopping means are provided in the area of the valve cartridge to axially secure the sleeve in the mounted position, so that the sleeve can be slipped on axially and, after a given turn, is securely held axially in the mounted position over the entire range of traverse for adjusting the mixed water and the hand lever cannot be fastened to the adjusting lever until after the said turn has been made.
It can be attained with these features that the lever head housing can be made as a one-piece cap-like sleeve. The sleeve can hereby be economically made from a coloured plastic, whereby decorative coatings c:an also be advantageously applied to the outer surface.

An embodiment of the invention is shown in the drawings and shall be described in greater detail in the following, showing Fig. 1 a mixing valve in the form of a sink water faucet having a pull-out hand-spray head;

Fig. 7 the annular spring element shown in Fig. 6, in a top view;
Fig. 8 the annular element shown in Fig. 6, in a view from the bottom.
The faucet shown in Figure 1 is intended in particular for use on sinks and consists of a fixture body 1, a valve cartridge 2, a sleeve 3 as lever head housing and a hand lever 4. The fixture body 1 is thereby constructed in such a way that it can be firmly attached with fastening means 14 to a sink (not shown in the drawing) in an opening with fastening means 14.
Moreover, the inlets 15, 16 for cold and hot water as well as the mixed water outlet 17 which supplies the mixed water produced in the valve cartridge 2 to an outlet in the form of a pull-out hand spray 18, is led through the openings in the sink.
In the valve cartridge 2, there is a bottom part 22 in which inlets for cold and hot water as well as an outlet for mixed water are made. A stationary valve seat disk 23 with corresponding openings is placed on the bottom part 22. A
control disk 24 with a cover 25 is movably mounted in two degrees of freedom on the opposite front side of the valve seat disk 23. An opening is made in the control disk 24, said opening being closed on the one side by the cover 25, so that the three openings in the valve seat disk 23 can be selectively connected with one another via the opening.
To move the control disk 24, a swivel 27, on which the cover 25 is supported at the front end, is placed in the housing of the valve cartridge 2. Moreover, an adjusting lever 21 with a swivel or rotational axis 200 arranged at right angles to the central axis 20 is provided in the swivel 27. The adjusting lever 21 engages with a cross pin 21o formed on the inner lever arm in a fork-shaped receptacle of the cover 25.
An elbow 40 with a set screw 401 is securely fastened to the outer lever arm when mounted. Turned by 90° to the first fastening, the hand lever 4 with an extension ~41 is also securely fastened with a set screw 411 when installed.
If the adjusting lever 21 is now turned about its axis of rotation 200 with the hand lever 4, then the control disk 24 is shifted together with the cover 25 radially to the valve seat disk 23, as a result of which the total water flow rate can be adjusted. If, on the other hand, the adjusting lever 21 is now turned about the central axis 20 with the hand lever 4, then the control disk 24 with the cover 25 is turned accordingly to the valve seat disk 23, as a result of which the mixing ratio of the incoming cold and hot water or the mixed water temperature of the water delivered can be adjusted.
The valve cartridge 2 has an almost cylindrical housing which is braced against the base of a receiving bore 11 of the fixture body 1 with aid of a thrust collar 26 and two diametrically opposite tightening screws 262 (shown in Figure 2 in the drawings turned by 90°), whereby the separate openings in the valve seat disk 23 are connected with the corresponding channels in the fixture body 1 via hose sealings supported in the bottom part 22.
To sheathe the valve cartridge 2 protruding from the receiving bore 1T and the adjusting lever 21 with the elbow 40, a sleeve 3 is provided so as to be pivotable yet axially fixed on the casing area of the valve cartridge 2. An annular element 5, as shown especially in Figures 6 to 8 in the drawings is provided for this purpose. It consists of a collar 50 and a stop sleeve 51 which are each connected to one another at the front end via three casing-like springs 52. For a firm hold in the installed position, two opposite projections 53 to resist turning are formed on the inside wall of the collar 50 and stop sleeve 51 which partially surround the two tightening screws 262 when installed. Three almost symmetrical stops 501 are molded onto the collar 50 on the outer casing surface. In this case, the inner wall of the collar 50 has a groove 503 in the area of the stops 501, so that the stop 501 is spring-mounted. The entire annular element 5 is hereby made in one piece from plastic in the injection-molding process.
When installing the valve cartridge 2, the annular element 5 is first of all slipped on and then the thrust collar 26 screwed together with the tightening screws 262. The slip ring 6 was previously inserted into the fixture body 1, so that the stop sleeve 51, on the one hand, is now supported on the thrust collar 26, on the other hand, the springs 52 press the collar 50 against a stop edge 61 of the slip ring 6. This collar 50 accommodates the sleeve 3 is received with a bayonet joint. For this purpose, radially inwardly protruding annular segments 3l~are formed symmetrically on the inner casing of the sleeve 3. Between the annular segments 31, there are three symmetrically arranged free spaces 32, the width of which is slightly larger than the width of the stops 501 protruding radially outward from the collar 50. Thus, the sleeve 3 can be slipped onto the collar 50 in a bayonet-like axial manner and turned in the installed position, so that this subsequently results in an axial securing. In this case, the annular segments 32 have chamfers 311, so that when the collar 50 is turned it is shifted about 1 mm axially to the thrust collar 26, so that, when the bayonet lock is engaged, the sleeve 3 is pressed against the slide ring 6 by the springs 52 and thus obtains its guide. Preferably, a stop 501 and a free space 32 are made out somewhat wider than the other two, so that the sleeve 3 can only be mounted in one pivotal position on the annular element 5, whereby the ring segments 31 are made in such a way that, after having been fixed in position, the sleeve 3 is turned by 180°, after which the sleeve 3, in this rotational position, is axially secured over the entire range of traverse of 100° of the adjusting lever 21 in the valve cartridge 2 to set the mixing ratio. To ensure that the sleeve 3 is also guided radially, relatively free from play on the collar 50, the stops 501 are moreover spring-mounted with aid of grooves 503 on the inside wall of the collar 50, so that they press elastically against the inside wall of the sleeve 3, whereby the outside surface of the stops 501 are spherical so as to fit smoothly. To enable a frictionless turning connection, the annular element 5 is made of. an easily slidable plastic. Moreover, penetration of dirt particles or liquids at the transition point from the fixture body 1 to the sleeve 3 is prevented to a large extent by placing the slip ring 6 on the front edge 12 and on the contact area of the sleeve 3.
The front side of the sleeve 3 facing away from the fixture body 1 is sealed with a hemispherical curvature 35, whereby the hand lever 4 with its extension 41 is fastened to the elbow 40 in the downward-pointing slit 33, as can be seen in particular in Figures 1 and 2. The slit 33 is thereby dimensioned in such a way that, when the hand lever 4 is turned about the central axis 20, the extension 41 also turns the sleeve 3 on the annular element 5 and the valve cartridge 2. The axial length of the slit 33 is measured in such a way that the hand lever 4 can be moved about the axis of rotation 200 within the scope of the stops preset in the valve cartridge to regulate the volume. To further cover the slit 33, the hand lever 4 has a projection 42 so that it is also largely avoided that spray water can penetrate into the sleeve 3.from below. In addition, the slit 33 has a lining 331 made of an easily slidable plastic for a low-wear guide. The lining 331 is hereby made as an insert which is forced into position, locked in position and/or glued. The lining 331 thereby protrudes slightly in the slit 33, so that the surface, in particular a chromium layer, of the sleeve 3 does not come in contact with the elbow 40.
By moving the hand lever 4 in direction of an arrow 43 (Figure 1), the amount of water delivered can be precisely set.
The mixing ratio or the temperature of the mixed water delivered can be determined by moving the hand lever 4 in direction of an arrow 44 (Figure 1). In this case, the sleeve 3 turns along with it. To indicate the mixture ratio or the mixed water temperature, a graduated scale 34 is placed on the sleeve 3 in the area of the fixture body 1, said scale interacting with a mark 13 provided on the fixture body 1.
The annular element can also be made in one piece on the valve cartridge instead of as a separate annular element 5, so that the sleeve 3 can then be directly connected with the valve casing in a bayonet-like manner.
A mixing valve of this generic type is known from the European patent publication number 0 140 275 B1. In this case, the lever head housing is made in two parts and consists of a casing sleeve and a protective cap. Moreover, a bushing which can be screwed into a receiving bore on the fixture is required to secure and guide the lever head housing.
It is the object of the invention to improve a mixing valve, in particular with respect to a lever head housing.
According to the invention, this object is solved therein that the sleeve adjoins and is guided with a front end in the area of the fixture, whereby clamping and stopping means are provided in the area of the valve cartridge to axially secure the sleeve in the mounted position, so that the sleeve can be slipped on axially and, after a given turn, is securely held axially in the mounted position over the entire range of traverse for adjusting the mixed water and the hand lever cannot be fastened to the adjusting lever until after the said turn has been made.
It can be attained with these features that the lever head housing can be made as a one-piece cap-like sleeve. The sleeve can hereby be economically made from a coloured plastic, whereby decorative coatings c:an also be advantageously applied to the outer surface.

An embodiment of the invention is shown in the drawings and shall be described in greater detail in the following, showing Fig. 1 a mixing valve in the form of a sink water faucet having a pull-out hand-spray head;
Fig. 2 a part of the mixing valve shown in Fig. l, in an enlarged representation in the longitudinal section;

Fig. 7 the annular spring element shown in Fig. 6, in a top view;
Fig. 8 the annular element shown in Fig. 6, in a view from the bottom.
The faucet shown in Figure 1 is intended in particular for use on sinks and consists of a fixture body 1, a valve cartridge 2, a sleeve 3 as lever head housing and a hand lever 4. The fixture body 1 is thereby constructed in such a way that it can be firmly attached with fastening means 14 to a sink (not shown in the drawing) in an opening with fastening means 14.
Moreover, the inlets 15, 16 for cold and hot water as well as the mixed water outlet 17 which supplies the mixed water produced in the valve cartridge 2 to an outlet in the form of a pull-out hand spray 18, is led through the openings in the sink.
In the valve cartridge 2, there is a bottom part 22 in which inlets for cold and hot water as well as an outlet for mixed water are made. A stationary valve seat disk 23 with corresponding openings is placed on the bottom part 22. A
control disk 24 with a cover 25 is movably mounted in two degrees of freedom on the opposite front side of the valve seat disk 23. An opening is made in the control disk 24, said opening being closed on the one side by the cover 25, so that the three openings in the valve seat disk 23 can be selectively connected with one another via the opening.
To move the control disk 24, a swivel 27, on which the cover 25 is supported at the front end, is placed in the housing of the valve cartridge 2. Moreover, an adjusting lever 21 with a swivel or rotational axis 200 arranged at right angles to the central axis 20 is provided in the swivel 27. The adjusting lever 21 engages with a cross pin 21o formed on the inner lever arm in a fork-shaped receptacle of the cover 25.
An elbow 40 with a set screw 401 is securely fastened to the outer lever arm when mounted. Turned by 90° to the first fastening, the hand lever 4 with an extension ~41 is also securely fastened with a set screw 411 when installed.
If the adjusting lever 21 is now turned about its axis of rotation 200 with the hand lever 4, then the control disk 24 is shifted together with the cover 25 radially to the valve seat disk 23, as a result of which the total water flow rate can be adjusted. If, on the other hand, the adjusting lever 21 is now turned about the central axis 20 with the hand lever 4, then the control disk 24 with the cover 25 is turned accordingly to the valve seat disk 23, as a result of which the mixing ratio of the incoming cold and hot water or the mixed water temperature of the water delivered can be adjusted.
The valve cartridge 2 has an almost cylindrical housing which is braced against the base of a receiving bore 11 of the fixture body 1 with aid of a thrust collar 26 and two diametrically opposite tightening screws 262 (shown in Figure 2 in the drawings turned by 90°), whereby the separate openings in the valve seat disk 23 are connected with the corresponding channels in the fixture body 1 via hose sealings supported in the bottom part 22.
To sheathe the valve cartridge 2 protruding from the receiving bore 1T and the adjusting lever 21 with the elbow 40, a sleeve 3 is provided so as to be pivotable yet axially fixed on the casing area of the valve cartridge 2. An annular element 5, as shown especially in Figures 6 to 8 in the drawings is provided for this purpose. It consists of a collar 50 and a stop sleeve 51 which are each connected to one another at the front end via three casing-like springs 52. For a firm hold in the installed position, two opposite projections 53 to resist turning are formed on the inside wall of the collar 50 and stop sleeve 51 which partially surround the two tightening screws 262 when installed. Three almost symmetrical stops 501 are molded onto the collar 50 on the outer casing surface. In this case, the inner wall of the collar 50 has a groove 503 in the area of the stops 501, so that the stop 501 is spring-mounted. The entire annular element 5 is hereby made in one piece from plastic in the injection-molding process.
When installing the valve cartridge 2, the annular element 5 is first of all slipped on and then the thrust collar 26 screwed together with the tightening screws 262. The slip ring 6 was previously inserted into the fixture body 1, so that the stop sleeve 51, on the one hand, is now supported on the thrust collar 26, on the other hand, the springs 52 press the collar 50 against a stop edge 61 of the slip ring 6. This collar 50 accommodates the sleeve 3 is received with a bayonet joint. For this purpose, radially inwardly protruding annular segments 3l~are formed symmetrically on the inner casing of the sleeve 3. Between the annular segments 31, there are three symmetrically arranged free spaces 32, the width of which is slightly larger than the width of the stops 501 protruding radially outward from the collar 50. Thus, the sleeve 3 can be slipped onto the collar 50 in a bayonet-like axial manner and turned in the installed position, so that this subsequently results in an axial securing. In this case, the annular segments 32 have chamfers 311, so that when the collar 50 is turned it is shifted about 1 mm axially to the thrust collar 26, so that, when the bayonet lock is engaged, the sleeve 3 is pressed against the slide ring 6 by the springs 52 and thus obtains its guide. Preferably, a stop 501 and a free space 32 are made out somewhat wider than the other two, so that the sleeve 3 can only be mounted in one pivotal position on the annular element 5, whereby the ring segments 31 are made in such a way that, after having been fixed in position, the sleeve 3 is turned by 180°, after which the sleeve 3, in this rotational position, is axially secured over the entire range of traverse of 100° of the adjusting lever 21 in the valve cartridge 2 to set the mixing ratio. To ensure that the sleeve 3 is also guided radially, relatively free from play on the collar 50, the stops 501 are moreover spring-mounted with aid of grooves 503 on the inside wall of the collar 50, so that they press elastically against the inside wall of the sleeve 3, whereby the outside surface of the stops 501 are spherical so as to fit smoothly. To enable a frictionless turning connection, the annular element 5 is made of. an easily slidable plastic. Moreover, penetration of dirt particles or liquids at the transition point from the fixture body 1 to the sleeve 3 is prevented to a large extent by placing the slip ring 6 on the front edge 12 and on the contact area of the sleeve 3.
The front side of the sleeve 3 facing away from the fixture body 1 is sealed with a hemispherical curvature 35, whereby the hand lever 4 with its extension 41 is fastened to the elbow 40 in the downward-pointing slit 33, as can be seen in particular in Figures 1 and 2. The slit 33 is thereby dimensioned in such a way that, when the hand lever 4 is turned about the central axis 20, the extension 41 also turns the sleeve 3 on the annular element 5 and the valve cartridge 2. The axial length of the slit 33 is measured in such a way that the hand lever 4 can be moved about the axis of rotation 200 within the scope of the stops preset in the valve cartridge to regulate the volume. To further cover the slit 33, the hand lever 4 has a projection 42 so that it is also largely avoided that spray water can penetrate into the sleeve 3.from below. In addition, the slit 33 has a lining 331 made of an easily slidable plastic for a low-wear guide. The lining 331 is hereby made as an insert which is forced into position, locked in position and/or glued. The lining 331 thereby protrudes slightly in the slit 33, so that the surface, in particular a chromium layer, of the sleeve 3 does not come in contact with the elbow 40.
By moving the hand lever 4 in direction of an arrow 43 (Figure 1), the amount of water delivered can be precisely set.
The mixing ratio or the temperature of the mixed water delivered can be determined by moving the hand lever 4 in direction of an arrow 44 (Figure 1). In this case, the sleeve 3 turns along with it. To indicate the mixture ratio or the mixed water temperature, a graduated scale 34 is placed on the sleeve 3 in the area of the fixture body 1, said scale interacting with a mark 13 provided on the fixture body 1.
The annular element can also be made in one piece on the valve cartridge instead of as a separate annular element 5, so that the sleeve 3 can then be directly connected with the valve casing in a bayonet-like manner.
