Definitions
- the invention relates to a valve upper part for sanitary fittings, with a head piece which is axially penetrated by a control spindle, via which a valve body arranged in the head piece can be actuated, and which is connected to an operating device comprising a handle.
- valve tops The outlet of media from fittings is controlled with the help of valve tops.
- the valve top is screwed into the housing of a fitting using its head piece.
- Valve tops of the aforementioned type are known in a wide variety of designs.
- EP 3 062 002 A1 discloses a valve top that has a head piece through which a spindle passes. In the head piece, this spindle is positively connected to a control disk that rests against a stationary inlet disk. The water flow is controlled by rotating the control disk relative to the inlet disk.
- the front side protruding from the head piece is designed as an external polygon on the outside and is provided with a threaded blind hole on the inside for the positive attachment of a rotary handle.
- EP 2 522 887 A1 also discloses a valve upper part in which a valve body is provided to control the flow of a fluid, which can be moved linearly within the head piece via a spindle.
- a spindle is rotatably mounted in a head piece and is connected via a thread to a valve body that is guided axially in the head piece in a rotationally secure manner. A rotation of the spindle thus causes an axial movement of the valve body within the head piece.
- valve top When designing fittings, it is increasingly desired that the valve top can be operated using a push button or key. Electromagnetically operated valves are regularly used for this purpose. The disadvantage of these valve tops, however, is that the electromagnetic contacts are affected when the valve top is screwed or glued. which affects reliability. In addition, such valves require an additional voltage source. In addition, quantity control is generally not possible with these valves.
- EP 3 366 959 A1 proposes a valve upper part in which the handle has a control cap with which it can be moved along the head piece and via which a control piston can be actuated, with a curved track having two locking positions being introduced into the outer surface of the head piece, into which a guide pin arranged on the control cap engages.
- valve top part shown above also known as a "push valve”
- this valve is limited to push operation.
- tasks that require push operation such as switching the water outlet (shower/waterfall shower) or retracting the valve handle when not in use) and rotary operation, for example to adjust the water flow rate, the use of several such "push valves" is necessary.
- the invention is based on the object of providing a valve top that enables push-button operation as well as rotary operation. According to the invention, this object is achieved by a valve top with the features of patent claim 1.
- the invention provides a valve upper part that enables push-button operation as well as rotary operation. Because the handle can be moved relative to the head piece coaxially to the control spindle and is also rotatable relative to the head piece and is connected to the control spindle in a rotationally fixed manner at least in one axial position, in addition to a possible push-button operation, enables the transmission of torque to the control spindle if required.
- the handle has an adjusting sleeve which is provided with an internal toothing and which engages in an external toothing of a driver connected to the control spindle, whereby the handle is guided axially displaceably along the driver. This enables a transmission of torque from the handle to the control spindle in different axial positions of the handle.
- the handle can be fixed in at least two axial positions via an arranged locking device.
- the locking device preferably comprises a control piston (5) which is guided in a control cylinder (3) and which has a control slot (52) into which an engagement part arranged on the control cylinder (3) engages. This results in a compact locking device which is integrated into the operating unit.
- the engagement part is formed by at least one ball, which is guided in the control cylinder so that it can move radially and circumferentially. This prevents the handle from rotating when it is operated, as indicated by the at least one ball. Balls also have the advantage over the guide pins known in the prior art that malfunctions that occasionally occur due to guide pins or their guides being deformed by overloading are avoided.
- the adjusting sleeve surrounds the control piston at least in part. This guides the handle along the control piston, with the locking device acting between the control piston and the control cylinder arranged in the adjusting sleeve.
- the control piston has the driver, in whose external teeth the internal teeth of the adjusting sleeve engage.
- control piston has a non-circular outer cross-section and the control cylinder has an inner cross-section corresponding to this outer cross-section, whereby the control piston is guided in the control cylinder in a rotationally fixed but displaceable manner.
- a spring is arranged between the control cylinder and the control piston, which is pre-tensioned against the control cylinder. This causes the control cylinder connected to the handle to automatically return along the control piston after an actuating force is applied.
- the operating device has a receptacle for a rotationally fixed connection to a connection section of the control spindle, which is arranged on the control piston.
- This enables a transmission of torque from the handle to the control piston and the control spindle connected to it.
- By pressing on the handle it can be moved out of a recessed position via the locking device, after which the control spindle can be rotated by turning the handle.
- This also enables the operating device to be easily mounted on the control spindle.
- a detachable connection a simple replacement of a defective operating device or a simple retrofitting of an already installed valve top is also possible.
- the control cylinder has an external thread onto which an adapter piece is screwed with its internal thread, whereby the adapter piece is held in the adjusting sleeve of the handle in a rotationally fixed and longitudinally displaceable manner.
- This enables a fine adjustment of the axial position of the handle on the spindle of a valve upper part installed in a wall.
- a longitudinal adjustment of the adapter piece along the external thread of the control piston takes place by turning the handle. Inaccuracies in the When installing a valve top and the control spindle is usually shortened to the required length, this can be compensated for by adjusting the adapter piece.
- the adapter piece has locking lugs, with at least one locking groove being arranged inside the adjusting sleeve, with which the locking lugs can be locked in a defined position of the adapter piece.
- At least two locking grooves are arranged inside the adjusting sleeve, preferably axially spaced from one another, and preferably radially circumferentially.
- This enables a first axial positioning of the adapter piece for adjustment and a second defined positioning of the adapter piece in the operating position with engagement of its internal toothing in the external toothing of the control piston.
- the two axial positions can also limit two switching positions that can be controlled by different axial positions of the control spindle. For this, it would be necessary for the spindle to be connected to the control cylinder.
- an installation sleeve is arranged, the inner diameter of which essentially corresponds to the outer diameter of the handle, whereby the position of the handle can be adjusted at a defined distance from the installation sleeve.
- the installation sleeve preferably has a circumferential collar which, when the handle is positioned in a defined position in the installation sleeve, forms a common plane with the surface of the handle. This enables a visually appealing integration of the handle into a plane surrounding it.
- the collar can be designed either in the shape of a ring or in the form of a plate of any geometric shape.
- the present invention further relates to a sanitary fitting with a valve upper part according to patent claim 13.
- the adjustment position is the position of the handle in which the locking lugs of the adapter piece engage in the second, lower locking groove of the adjusting sleeve. In this position, adjustment is possible via the thread engagement between the external thread of the control cylinder and the internal thread of the adapter piece. The internal teeth of the adjusting sleeve are not engaged with the external teeth of the control piston.
- the operating position is the position of the handle in which the locking lugs of the adapter piece engage in the first, upper locking groove of the adjusting sleeve.
- the internal teeth of the adjusting sleeve are in engagement with the external teeth of the control piston. Adjustment via the thread engagement between the external thread of the control cylinder and the internal thread of the adapter piece is not possible.
- the operating position is the position of the handle in which the balls are in the upper position of the control gate.
- the handle is thus "extended” for easy operation.
- the retracted position is the position of the handle in which the balls rest in the holding area of the control link.
- the handle is locked in a retracted position in which, for example, the handle is flush with the area surrounding it.

- an operating device which comprises a handle 1, in which an adapter piece 2 is arranged so as to be axially displaceable, which receives a control cylinder 3 with which it is in threaded engagement, which is provided at the end with a limiting sleeve 4 and in which a control piston 5 is arranged so as to be axially displaceable, which is provided at the end with a driver piece 6 and which has a receptacle for form- a tight connection with the non-circular connection section 82 of the control spindle 81 of a valve upper part 8.
- the connection section of the control spindle 81 can also be cylindrical. In this case, a rotationally fixed connection, for example by means of gluing, is required.
- the handle 1 is formed from a hollow cylindrical, pot-shaped handle 11, which has a central threaded hole 12 on the inside, into which an adjusting sleeve 14 is screwed and glued coaxially to the cylindrical side wall of the handle 11.
- the handle 1 can also be made in one piece.
- the handle 11 is provided with a sealing groove 13, which accommodates an O-ring 131.
- the handle 11 and adjusting sleeve 14 are manufactured as turned brass parts.
- the adjusting sleeve 14 is essentially hollow-cylindrical and has a first section 141, which is followed by a second, larger-diameter section 143.

- a first, upper locking groove 16 and a second, lower locking groove 17 are arranged at a distance from this in the first section 141.
- the largely dodecagonal cross-sectional contour of the inner surface of the first section 141 serves to accommodate the adapter piece 2 in a rotationally fixed manner, the outer surface of which has a corresponding dodecagonal cross-sectional contour.
- the largely dodecagonal cross-sectional contour of the inner surface of the first section 141 and the outer surface of the adapter piece 2 is achieved by six rectangular flattened portions 142, 21 introduced into the cylinder surface at regular intervals.
- the second section 143 is provided with an internal toothing 18 which extends largely over the entire inner surface of the second section 143.

- the adapter piece 2 is essentially hollow-cylindrical and, as already explained, has an outer surface with an almost dodecagonal cross-section that corresponds to the inner surface of the adjusting sleeve 14.
- a rectangular recess is made in the adapter piece 2 on its side facing the threaded hole 12 of the handle 11, which defines six locking tongues 22 arranged at regular intervals from one another, which have radially extending, outwardly projecting locking lugs 23 for engagement in the locking grooves 16, 17 of the adjusting sleeve 14.

- the inner diameter tapered section 55 is followed by an inner diameter expanded section 58, through which a shoulder 57 is formed, which serves as a spring seat for a compression spring 59.
- the driver piece 6 is designed as a substantially hollow cylindrical brass turned part and has, at its end opposite the control cylinder 3, a section 61 with a tapered inner diameter, which is provided with an internal thread 62.
- the outer surface of the driver piece 6 is provided with an external toothing 63 for engagement in the internal toothing 18 of the adjusting sleeve 14.
- the adapter piece 2 is screwed with its internal thread 24 onto the external thread 33 of the control cylinder 3.
- the control piston 5 is inserted into the control cylinder 3 and is guided in the control cylinder 3 in a rotationally fixed but axially displaceable manner by its non-circular outer surface, which corresponds to the inner surface of the control cylinder 3.
- the balls 38 which pass through the elongated holes 35 of the control cylinder 3 in certain areas, each engage in a control slot 52 of the control piston 5.
- the compression spring 59 rests on the shoulder 57 of the control piston 5 and is pre-tensioned on its opposite side against the adjusting sleeve.
- the internal toothing of the adjusting sleeve 14 is in engagement with the external toothing 63 of the driver piece 6.
- the valve upper part 8 is designed in the embodiment according to EP 1 696 162 A1. It has a head piece 83 through which the control spindle 81 passes axially.
- valve top 8 When installing a sanitary fitting, such as a shower fitting, on the wall, the water pipes are connected by the installer in the wall to a valve top 8 of the fitting.
- the valve top 8 usually has a long control spindle 81, which is cut to the desired length after completion of the work on the wall, including any tiling work.
- the wall passage is provided with an installation sleeve 7 framing the control spindle 81.
- the control spindle 81 is inserted with its external toothing into the receptacle 54 of the control piston 5, which has an internal toothing, and is fastened using a countersunk screw 82.
- FIG. 1 Such an installation situation is shown schematically in Figure 1.
- the handle 11 of the handle 1 protrudes significantly beyond the collar 71 of the Installation sleeve 7, which in this embodiment has an external thread 72 that is screwed with a lock nut 73.
- the handle 1 can now be moved along the adapter piece 2 with its adjusting sleeve 14, which is connected to the adapter piece 2 in a longitudinally displaceable manner, by pulling on the handle 11 until the locking lugs 23 of the locking tongues 22 engage in the second, lower locking groove 17 of the adjusting sleeve 14. In this position, the internal toothing 18 of the adjusting sleeve 14 is not engaged with the external toothing 63 of the driver piece 6 (see Figure 2).
- the adapter piece 2 which is connected to the adjusting sleeve 14 in a rotationally fixed manner, can now be adjusted axially relative to the control cylinder 3 via the threaded engagement with the external thread 33 of the control cylinder 3 (see Figure 3).
- the adjusting sleeve 14 can then be moved along the adapter piece 2 again by pressing on the handle 11 until the locking lugs 23 of the locking tongues 22 engage in the first, upper locking groove 16 of the adjusting sleeve 14.
- the operating unit is now adjusted relative to the installation sleeve 7. It is in the operating position (see Figure 4).
- the control cylinder 3 By pressing the handle 1, the control cylinder 3 is moved along the control piston 5 via the adjusting sleeve 14, whereby the balls 38 run in the control guide 52. The balls 38 can move radially in the elongated holes 35. At the stop of the control piston 5 in the control cylinder 3, the balls 38 the switching section 521 of the respective control cam 52. After releasing the handle 1, the control cylinder 3 is moved back by the restoring force of the compression spring 59, whereby the balls 38 are moved into the holding area 522 of the control link 52. In this position, the handle 1 is held by the balls 38. In this position, the handle 1 is completely sunk into the installation sleeve 7 in the retracted position, with the surfaces of the handle 1 and the collar 71 of the installation sleeve 7 lying on one level.
- the operating device selected as the embodiment according to Figure 16 is very compact. It again comprises a handle 1', in which an adapter piece 2' is arranged so that it can move axially, which receives a control cylinder 3' with which it is in threaded engagement, in which a control piston 5' is arranged so that it can move axially and which has a receptacle for the positive connection to the non-circular connection section 82 of the control spindle 81 of a valve upper part 8.
- the driver piece 6' is arranged at the end of the control cylinder 3' and at the same time takes on the function of the limiting sleeve 4, which is why a separate limiting sleeve is not present here.
- the handle 1' is provided with an internal thread 12 into which an adjusting sleeve 14' is screwed and glued.
- the adjusting sleeve 14' in turn has a first section 141, which is followed by a second section 143. While the first section 141 essentially corresponds to the first section of the adjusting sleeve 14 of the first embodiment, the second section 143 is significantly shorter.
- the second section 143 is in turn provided with an internal toothing 18 which extends largely over its inner surface, the inner surface of the second section 143 having a largely octagonal cross-sectional contour which is achieved by four rectangular flattened areas 144 which are regularly spaced apart in the inner surface of the cylinder provided with the internal toothing 18.
- the adapter piece 2' is also shorter in this embodiment. Instead of the locking tongues arranged at regular intervals from one another, a circumferential groove 22' is arranged here, which accommodates an O-ring 25 for engagement in the locking grooves 16, 17 of the adjusting sleeve 14.
- the control cylinder 3' is also shorter, which is particularly due to the shorter upper part provided with the external thread.
- a ball 38 is again introduced into each of the two elongated holes 35, the diameter of which is slightly smaller than the width of the elongated hole 35, so that it protrudes through the respective elongated hole 35 in some areas and is guided radially and circumferentially between the webs 36.
- the driver piece 6' with its internal thread 62 is screwed onto the control cylinder 3' and engages around the webs 36, which in turn limits a ball cage for the two balls 38.
- the driver piece 6' therefore also takes on the task of the limiting sleeve present in the first embodiment.
- control piston 5' essentially corresponds to the control piston 5 of the first embodiment, but the end-side, diameter-reduced shoulder provided with an external thread is not present, since the In this second embodiment, the slave piece 6' is not attached to the control piston 5', but to the control cylinder 3'.
- the driver piece 6' essentially corresponds to the driver piece 6 of the first embodiment, with the only additional feature being that a circumferential annular groove 64 for receiving a sealing ring is arranged on the inside adjacent to the section 61 with a tapered inner diameter.
- the handle 1' can now be moved along the adapter piece 2' with its adjusting sleeve 14', which is connected to the adapter piece 2' in a longitudinally movable manner, by pulling on the handle 11 until the O-ring 25' engages in the second, lower locking groove 17 of the adjusting sleeve 14'. In this position, the internal toothing 18 of the adjusting sleeve 14' is not engaged with the external toothing 63 of the driver piece 6' (see Figure 17).
- the adapter piece 2' which is connected to the adjusting sleeve 14' in a rotationally fixed manner, can now be adjusted axially relative to the control cylinder 3' via the threaded engagement with the external thread 33 of the control cylinder 3'.
- a pulling force is required to move the O-ring 25 out of the first, upper locking groove 16 in order to move it into the second, lower locking groove 17.
- a loss prevention device is arranged between the adapter piece 2' and the adjusting sleeve 14'.
- the adjusting sleeve 14' has an internally circumferential internal thread web 140 into which an external thread web 20 arranged on the outside of the adapter piece 2' can be screwed.
- the adapter piece 2' is screwed with its external thread web 20 into the circumferential internal thread web 140 of the adjusting sleeve 14' and then tightened.
- the external thread web 20 is then located behind the internal thread web 140 when viewed in the direction of the handle part 11.
- the adapter piece 2' is thus held axially in the adjusting sleeve 14' in a loss-proof manner.
- the adjusting sleeve 14 can then be moved along the adapter piece 2' again by pressing on the handle 11 until the O-ring 25 engages in the first, upper locking groove 16 of the adjusting sleeve 14.
- the operating unit is now adjusted relative to the installation sleeve 7. It is in the operating position (see Figure 19).
- the handle 1' By pressing the handle 1', it can be moved completely into a position recessed in the installation sleeve 7, corresponding to the operating unit according to the above first embodiment, in which position it is held by the balls located in the holding area 522 of the control link 52 of the control cylinder.
- Figure 29 shows a valve upper part in a third embodiment in which no locking device is present.
- An operating device is arranged at the end of the control spindle 81, which in turn comprises a handle 1 which has a handle 11 and an adjusting sleeve 14 connected to it and in which an adapter piece 2 is arranged so as to be axially displaceable in the manner described above.
- the adapter piece here accommodates a coupling cylinder 41, the adapter piece 2 being screwed with its internal thread 24 onto the external thread 42 of the coupling cylinder 41.
- the coupling cylinder 41 has a receptacle 43 for positive connection with the non-circular connection section 82 of the control spindle 81 of the valve upper part 8.
- the coupling cylinder 41 has a driver shoulder 44 with an enlarged diameter, which runs around the outside - corresponding to the external toothing 63 of the driver piece 6 of the previously described embodiment - with an external toothing 45 for engagement in the internal toothing 18 of the adjusting sleeve 14 of the handle
- the handle 1 can now be moved on the adapter piece 2 in accordance with the first embodiment by pulling on the handle 11 until the locking lugs 23 of the locking tongues 22 engage in the second, lower locking groove 17 of the adjusting sleeve 14. In this position, the internal toothing 18 of the adjusting sleeve 14 is disengaged from the external toothing 45 of the driver shoulder 44 (see Figure 16).
- the adapter piece 2 which is connected to the adjusting sleeve 14 in a rotationally fixed manner, can now be adjusted axially relative to the latter via the threaded engagement with the external thread 42 of the coupling cylinder 1.
- the adjusting sleeve 14 can then be moved along the adapter piece 2 again by pressing on the handle 11 until the locking lugs 23 of the locking tongues 22 engage in the first, upper locking groove 16 of the adjusting sleeve 14.
- the operating unit is now adjusted relative to the installation sleeve 7.
- the external toothing 45 of the driver shoulder 44 is now again in engagement with the internal toothing 18 of the adjusting sleeve 14, the thread engagement between the adapter piece
- the thread engagement between the adapter piece 2 and the adjusting sleeve 14 can also be blocked by means of locking means arranged in the handle, for example by an axial displacement of the adjusting sleeve, whereby the threads of the adapter piece and the adjusting sleeve can be disengaged.
- the adapter piece is preferably made of plastic, which allows axial overrun of the thread of the adjusting sleeve.
