[0003] - 1 - Shower head for a sanitary fitting

[0004] The present invention relates to a shower head for a sanitary fitting, in particular a hand shower or overhead shower for dispensing liquid, especially water, in one or more spray patterns, such as rain jets, massage jets or aerated jets. Such shower heads are typically used at a kitchen sink, a washbasin, a shower or a bathtub.

[0005] Conventional shower heads dispense water with a fixed spray width. This can be impractical for different users or situations. In particular, the spray width is often too narrow for taller people, while it is perceived as too wide for shorter people or children. To achieve a wider spray width, a larger shower head is often necessary, which can have aesthetic drawbacks and be impractical in small showers. Furthermore, larger shower heads generally increase water consumption, which can be undesirable.

[0006] Shower heads are known where the shower head housing is hinged and therefore foldable or movable, allowing for different spray patterns. However, these designs are complex and cumbersome to use. Furthermore, the hinges can detract from the shower head's appearance and / or become calcified.

[0007] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a shower head whose spray width can be conveniently adjusted. Grohe AG

[0010] This problem is solved by a shower head according to the features of the independent claim. Further advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed individually in the dependent claims can be combined with one another in any technologically meaningful way and define further embodiments of the invention. Furthermore, the features specified in the claims are further specified and explained in the description, which also presents further preferred embodiments of the invention.

[0011] This is achieved using a shower head for a sanitary fitting, which has at least the following features:

[0012] - a housing with a fluid inlet for a fluid and an actuating element; - a plurality of nozzles, wherein at least one of the nozzles is rotatably or pivotably mounted relative to the housing; and

[0013] - an actuating element for rotating or swiveling at least one nozzle.

[0014] Sanitary fittings serve, in particular, to provide liquids, especially water, to sinks, washbasins, showers, and / or bathtubs as needed. For this purpose, cold water at a specific temperature and hot water at a specific temperature can be supplied to the sanitary fittings. These waters can be mixed by the fittings, for example, by means of a mixing valve or a thermostatic mixing cartridge, to create a mixture with the desired temperature. The cold water temperature is preferably a maximum of 25 °C, more preferably between 1 °C and 25 °C, and more preferably between 5 °C and 20 °C, and / or the hot water temperature is preferably a maximum of 90 °C, more preferably between 25 °C and 90 °C, and more preferably between 55 °C and 65 °C. The mixed water can then be supplied, for example, via a liquid line, pipe, or hose, to a shower head, which may be designed, for example, as a rain shower head or hand shower.The shower head can be permanently attached to a support, such as a wall or ceiling, or it can be moved by a user. Grohe AG.

[0017] The shower head has a housing with at least one liquid inlet for the liquid or mixed water. The housing may be made at least partially of metal and / or plastic. The housing is not hinged. The liquid can be supplied to the shower head via the liquid inlet of the housing. The liquid inlet can be connected to the liquid line, pipe, or hose of the sanitary fitting, for example, by means of a thread. From the liquid inlet, the liquid can be supplied to a multitude of nozzles. The liquid inlet can be connected to the nozzles via at least one liquid channel in the shower head. The liquid channel can extend through the housing and / or through a handle of the housing. The housing does not, in particular, have multiple (external) housing parts with nozzles that are connected to each other by a hinge and / or a swivel joint.The nozzles can be rotated and / or swiveled, particularly without moving the housing.

[0018] At least one, a plurality of, some, or all of the nozzles are rotatably or pivotably mounted relative to the housing. The nozzles allow the liquid, particularly in the form of jets, to be discharged into the surrounding area. Each nozzle can extend from a first longitudinal nozzle end along a longitudinal axis (particularly a straight one) to a second longitudinal nozzle end. Each nozzle can have a length of, for example, 0.5 mm to 10 mm (particularly parallel to the longitudinal nozzle axis). Each nozzle can have an inlet opening at the first longitudinal nozzle end through which the liquid can enter the nozzle, and / or an outlet opening at the second longitudinal nozzle end through which the liquid can be discharged into the surrounding area. A nozzle channel for guiding the liquid extends between the inlet opening and the outlet opening, particularly parallel to the longitudinal nozzle axis.The nozzle channel can have a nozzle diameter of, for example, 0.5 mm to 10 mm (especially perpendicular to the nozzle's longitudinal axis). Grohe AG.

[0020] -4 -

[0021] The nozzles can be made of an elastic or rigid material. They can be made at least partially of plastic, rubber, silicone, and / or metal. The shower head or housing can, for example, have 10 to 200 nozzles. The nozzles can be arranged on the housing, on a spray pattern element of the shower head, and / or in a nozzle array of the shower head or housing. The nozzles are arranged in the shower head so that the liquid can be dispensed evenly and / or precisely into the surrounding area. The nozzles can be arranged in a ring or circle on the shower head or housing. The nozzles can be arranged in several concentric circles, in radial lines, and / or in another geometric arrangement, particularly to create specific spray patterns.

[0022] The nozzles are rotatable and / or pivotable relative to the housing or mounted on the housing. The nozzles can be rotated and / or pivoted relative to the housing. By rotating and / or pivoting, the spray direction of the nozzles or the liquid can be changed. By rotating and / or pivoting the nozzles, the orientation of the nozzle longitudinal axes can be changed. By rotating and / or pivoting the nozzles, the spray width of the shower head can be changed, in particular reduced and / or increased. The spray width refers in particular to the diameter of a spray jet produced jointly by the nozzles. The spray width can be measured in a plane that is, in particular, orthogonal to the spray direction and / or has a distance from the shower head, for example, 500 mm or at least 100 mm.The spray width indicates how far the spray jet extends laterally and describes its propagation, for example, in a horizontal direction. A shower head's minimum spray width can range from 10 mm to 150 mm, and / or its maximum from 200 mm to 500 mm. A larger spray width results in a wider distribution of the liquid, while a smaller spray width leads to a more concentrated application. Grohe AG.

[0025] The nozzles can be rotatably or pivotably mounted in a bearing or bearing opening of the housing, a housing component, a fluid guide of the housing, and / or a jet former of the housing. Each nozzle can have a bearing section, which can be, for example, at least partially spherical and / or at least partially cylindrical. The bearing sections can be located, for example, at the first longitudinal ends of the nozzles or between the first and second longitudinal ends of the nozzles. The bearing sections can be arranged or mounted in the bearings or in the bearing openings. The bearings or the bearing openings can be at least partially congruent with the bearing sections of the nozzles, in order to ensure, in particular, a (substantially) backlash-free and / or movable mounting.

[0026] The shower head has an actuating element for rotating and / or swiveling the nozzles. The actuating element controls the rotation and / or swiveling movement of the nozzles. The actuating element allows the nozzles to be moved and / or swiveled, in particular mechanically, electrically, pneumatically, or hydraulically. The actuating element allows the spray width of the shower head to be adjusted or controlled (in particular, precisely), specifically increasing and / or decreasing it. Without actuation of the actuating element, the nozzles do not move relative to the housing. The actuating element can be designed, for example, as a rotary knob, slider, lever, push button, touch sensor, or in another suitable form. The actuating element can be located on the shower head or on the housing. The actuating element can be movably mounted on the shower head or on the housing. The actuating element can be spaced apart from the shower head or housing.The actuator may be positioned at a distance from the housing and / or connected to the shower head via a cable or wireless connection. The actuator may be movable in a first direction of movement or rotatable in a first direction of rotation, thereby increasing the spray width. The actuator may also be movable in a second direction of movement or rotatable in a second direction of rotation, which Grohe AG.

[0027] P23-0686W001

[0028] - 6 -

[0029] The spray width can be reduced. The second direction of movement can be opposite to the first direction of movement and / or the second direction of rotation can be opposite to the second direction of rotation. The operating element is designed to be user-friendly and / or is positioned on the shower head or housing in a way that allows for easy operation by the shower head user.

[0030] The nozzles can be arranged on an at least partially elastic element of the housing. The elastic element can consist at least partially of an elastic material, such as rubber or silicone. The elastic element can be a flexible component of the housing. The elastic element can form at least a partial outer surface of the housing and / or a jet former. The elastic element can be flat or designed as a mat. The elastic element can have a material thickness of, for example, 1 mm to 4 mm and / or an outer surface diameter of, for example, 20 mm to 200 mm (particularly outside the nozzles). The elastic element can have a round, oval, or polygonal base. The elastic element can be attached to the housing, particularly around its circumference. The elastic element is deformable, particularly mechanically, and / or can return to its original shape after deformation.The elastic element allows for adjustment of the orientation or alignment of the nozzles attached to it. Deformation can include bending, stretching, compression, and / or bulging. The elasticity of the element ensures reliable and long-lasting operation, even with repeated adjustments.

[0031] The at least partially elastic element can be formed as a single piece with the nozzles. The elastic element and the nozzles can be made of the same material. The elastic element and the nozzles can be a single component made of multiple materials and / or manufactured using a process such as injection molding, 3D printing, or comparable manufacturing techniques. The one-piece design ensures a seamless connection between the Grohe AG

[0032] P23-0686W001

[0033] - 7 -

[0034] The elastic element and the nozzles are designed to ensure a secure fit, thus avoiding potential weak points such as joints or glued joints. This improves the shower head's stability, leak-proofness, and durability. The one-piece design also allows for efficient manufacturing and reduces assembly and maintenance requirements. The elastic element serves both as a flexible adjustment mechanism and as a secure fixing point for the nozzles, simplifying the overall construction and simultaneously improving the precision of the nozzle movement.

[0035] The at least partially elastic element can be adjusted to rotate or swivel the nozzles relative to the housing. Adjusting the elastic element can involve deformation, which may include bending, stretching, compression, and / or bulging. By adjusting or deforming the elastic element, the orientation of the nozzles can be changed, thereby adjusting their spray direction and the resulting spray width of the shower head. The adjustment and / or deformation of the elastic element can be symmetrical or asymmetrical. This allows for flexible and reliable adjustment of the spray width without the need for additional moving parts such as joints or hinges. This reduces the complexity of the design and increases the ease of maintenance and the shower head's durability.

[0036] The shower head may have an adjusting element for adjusting the at least partially elastic element. The adjusting element may be mechanically connected or coupled to the elastic element. The adjusting element is, in particular, adjustable or controllable via the actuating element. By actuating or adjusting the adjusting element, the elastic element can be deformed and / or moved into a position that changes the orientation of the nozzles relative to the housing. This allows for adjustment of the nozzle spray direction and enables control of the shower head's spray width. The adjusting element may be at least partially located within the housing. The adjusting element may be of the type of a ballpoint pen refill (Grohe AG).

[0037] P23-0686W001

[0038] - 8 -

[0039] The actuating element may be designed as a ballpoint pen mechanism and / or be part of a ballpoint pen mechanism. The ballpoint pen mechanism allows the actuating element to be adjusted, particularly along its longitudinal axis, to at least two positions. The ballpoint pen mechanism may be at least partially located within the housing. The actuating element may be part of the ballpoint pen mechanism.

[0040] The adjusting element offers a simple and efficient way to expand the functionality of the shower head without unnecessarily complicating the design. It ensures reliable control of the deformation of the elastic element, thus enabling precise and flexible adjustment of the spray width.

[0041] The adjusting element can be a spindle. The spindle is connected to or attached to the elastic element, particularly at a longitudinal end. The spindle can be rotatable about an axis of rotation. The spindle can be adjustable by rotating it parallel to the axis of rotation. Adjusting the spindle can cause the elastic element to be adjusted or deformed. By rotating the spindle about the axis of rotation, the elastic element can be moved into different positions, thereby changing the orientation of the nozzles. This allows for precise adjustment of the spray width of the shower head.

[0042] The actuating element can consist at least partially of a shape memory material or an electroactive polymer. The actuating element can be designed at least partially as a sheet, sheet strip, or wire. The actuating element can be attached to a surface of the elastic element. The actuating element can be arranged at least partially within the elastic element or cast into the elastic element. The actuating element can extend over the (in particular, the entire) elastic element or over the (in particular, the entire) diameter of the elastic element. The shape memory material is a material that, after deformation by a Grohe AG

[0043] P23-0686W001

[0044] - 9 -

[0045] The electroactive polymer is a polymer that changes its shape and / or size when an electrical voltage is applied. The actuator can be connected to an electrical power source, such as a battery, and / or an electronic control. The change in shape of the actuator can cause the elastic element to bend or deform, thereby changing the orientation of the nozzles attached to it. This allows for flexible adjustment of the spray width of the shower head.

[0046] The shower head can have at least one cam guide for rotating or swiveling the nozzles. The shower head can have multiple cam guides, which are arranged, in particular, coaxially to one another. The cam guide is, in particular, at least partially located in the housing. The cam guide can be rotatably mounted about the axis of rotation. The cam guide can be actuated, moved, and / or rotated by the actuating element. The actuating element can be connected or coupled to the cam guide. The cam guide is mechanically coupled to the nozzles and designed such that its movement or rotation about the axis of rotation changes the orientation of the nozzles relative to the housing. The cam guide can be annular. The cam guide can extend along a plane orthogonal to the axis of rotation and / or can be designed such that it can effect synchronous adjustment of the nozzles.

[0047] The cam guide can have a groove into which the nozzles engage. The groove can be operatively connected to a guide section of the nozzles. The groove width can be dimensioned to provide (essentially) backlash-free guidance for the guide sections of the nozzles. The groove allows for control of nozzle movement by providing guidance for rotation and / or pivoting of the nozzles. The groove can extend along the cam guide. The groove can be arc-shaped. [The following appears to be unrelated and possibly a separate text fragment: Through the engagement Grohe AG]

[0048] P23-0686W001

[0049] - 10 - the guide sections of the nozzles in the groove allow a movement of the cam guide to be transferred to the nozzles, making them rotatable and / or pivotable relative to the housing.

[0050] The groove may have a wavy profile, at least partially. This can mean, in particular, that the groove extends alternately radially inwards and outwards. The groove's profile may resemble a sine wave. The radial distance of the groove to the axis of rotation of the cam guide may vary, especially at regular intervals.

[0051] The wave-like shape of the groove ensures that the nozzle guide sections move along a predetermined path during rotation of the cam track around the axis of rotation. This movement results in a synchronous rotation and / or pivoting of the nozzles (radially inwards or radially outwards), thus allowing the spray width of the shower head to be adjusted.

[0052] The groove can be ring-shaped.

[0053] The invention and its technical context are explained in more detail below with reference to the figures. It should be noted that the figures show particularly preferred embodiments of the invention, but that the invention is not limited to these. Identical components in the figures are designated with the same reference numerals. The figures show, by way of example and schematically:

[0062] Fig. 1 shows a first variant of a shower head 1 in a side view. The shower head 1 has a housing 2 with a liquid inlet 3. A liquid supply line (not shown) can be connected to the liquid inlet 3, via which the shower head 1 can be connected to a sanitary fitting (also not shown). Liquid can be supplied to the shower head 1 via the liquid inlet 3. The liquid can flow from the liquid inlet 3 through a liquid channel of the shower head 1 (not visible) to a plurality of nozzles 4. The nozzles 4 are formed on an elastic element 5, which is a spray former. The liquid can be discharged via the nozzles 4 into the surrounding area 12 of the shower head 1. The elastic element 5 can be adjusted by a user of the shower head 1 via an actuating element 10, so that the nozzles 4 can pivot relative to the housing 2.

[0063] Fig. 2 shows the first variant of the shower head 1 in a sectional view along section line 11-11 shown in Fig. 1. The elastic element 5 is round and attached to the housing 2 at its circumference 13. The shower head 1 has an adjusting element 6 in the form of a spindle 7. The adjusting element 6 is attached to a threaded sleeve 14 and to the elastic element 5 at a longitudinal end 15. The threaded sleeve 14 is screwed to a housing component 17 of the housing 2 via a thread 16. The threaded sleeve 14 is connected to the actuating element 10 shown in Fig. 1, by means of which the threaded sleeve 14 can be rotated about an axis of rotation 11 by a user of the shower head 1. By rotating the threaded sleeve 14 about the axis of rotation 11, the adjusting element 6 can be adjusted parallel to the axis of rotation 11. Grohe AG

[0066] By adjusting the adjusting element 6, the elastic element 5 can be extended to varying degrees, thus changing the orientation or spray angle of the nozzles 4. The adjusting element 6 can exert a compressive and / or tensile force on the elastic element 5. This force deforms the elastic element 5, causing it to be extended to a greater or lesser extent, depending on the degree of adjustment of the adjusting element 6. Changing the extension alters the orientation or tilt angle of the nozzles 4, thereby adjusting the spray width of the shower head 1.

[0067] Fig. 3 shows a second variant of the shower head 1 in a sectional view along section line 11-11 shown in Fig. 1. In the second variant of the shower head 1, the elastic element 5 is adjustable by an actuating element 6, which is a sheet metal strip made of a shape-memory material. The actuating element 6 extends over the elastic element 5 and is attached and / or supported at its longitudinal actuating element ends 18, 19 on the housing 2 of the shower head 1. The actuating element 6 is attached to the elastic element 5 between the longitudinal actuating element ends 18, 19. A temperature change of the actuating element 6, which can be generated, for example, by a heating element (not shown here) or by a current flowing through the actuating element 6, in particular due to an electrical resistance of the actuating element 6, causes a deformation of the actuating element 6. The deformation of the actuating element 6 leads to a bending or...The elastic element 5 protrudes and changes the orientation or angle of inclination of the nozzles 4 relative to the housing 2, thereby making the spray width of the shower head 1 adjustable.

[0068] Fig. 4 shows a third variant of the shower head 1 in a sectional view along section line 11-11 shown in Fig. 1. In Fig. 3, only two nozzles 4 of a plurality of nozzles 4 are visible, which are arranged in a ring around the axis of rotation 11 of a cam guide 8. The cam guide 8 is ring-shaped and rotatably mounted in the housing 2 about the axis of rotation 11. Grohe AG

[0071] The individual nozzles 4 extend along a nozzle longitudinal axis 20 from a first longitudinal nozzle end 21 to a second longitudinal nozzle end 22. A nozzle channel 23 extends from the first longitudinal nozzle end 21 along the nozzle longitudinal axis 20. The liquid can enter the nozzle channel 23 via the first longitudinal nozzle end 21 and flow through the nozzle channel 23 to the second longitudinal nozzle end 22. The liquid can be discharged to the surroundings 12 of the shower head 1 via the second longitudinal nozzle end 22. Between the first longitudinal nozzle end 21 and the second longitudinal nozzle end 22, each nozzle 4 has a cylindrical bearing section 24. The nozzles 4 are rotatably mounted with their respective bearing sections 24 in a bearing opening 25 of the housing 2 or a housing component of the housing 2 about a nozzle rotation axis 26.The nozzle rotation axis 26 extends orthogonally to the sleeve longitudinal axis 20, orthogonally to the rotation axis 11 and, in the case of the nozzles 4 visible in Fig. 4, perpendicular to the drawing plane of Fig. 4.

[0072] The nozzles 4 each have a guide section 27 at their first longitudinal nozzle end 21, which extends into a groove 9 of the cam guide 8. The cam guide 8 is rotatable about the axis of rotation 11 by means of the actuating element 10 shown in Fig. 1. When the cam guide 8 is rotated about the axis of rotation 11, the guide sections 27 of the nozzles 4 are guided in the groove 9, causing the nozzles 4 to rotate about their axes of rotation 26. This allows the alignment or the angle of inclination of the nozzles 4 relative to the housing 2 to be adjusted, thereby making the spray width of the shower head 1 adjustable. In Fig. 4, the nozzles 4 are in a first operating position in which the longitudinal axes 20 of the nozzles run parallel to the axis of rotation 11.

[0073] Fig. 5 shows the third variant of the shower head 1 in the same sectional view as in Fig. 4, after the cam guide 8 has been rotated about the axis of rotation 11. The groove 9 of the cam guide 8 has a wave-like profile as shown in Fig. 6, which, when the cam guide 8 is rotated about the axis of rotation 11, causes the nozzles 4 to rotate about their nozzle axes of rotation 26. By rotating the cam guide 8 about the axis of rotation 11, the nozzles 4 were Grohe AG

[0074] P23-0686W001

[0075] - 14 -

[0076] The nozzles are rotated into a second operating position about the nozzle rotation axes 26, such that the longitudinal axes 20 of the nozzles 4 run at an angle to the rotation axis 11 and the second longitudinal nozzle ends 22 of the nozzles 4 are adjusted outwards compared to the first operating position shown in Fig. 4. This allows the liquid to be discharged to the surroundings 12 via the nozzles 4 with a wider spray width than in the first operating position shown in Fig. 4.

[0077] Fig. 6 shows a top view of the annular cam guide 8 of the third variant of the shower head 1 shown in Figs. 4 and 5. The wave-like shape of the groove 9 is particularly visible. The groove 9 extends along the annular cam guide 8 and has several sections that alternately extend inwards and outwards in a wave-like pattern in a radial direction 29. This wave-like geometry of the groove 9 causes the guide sections 27 of the nozzles 4, shown in Figs. 4 and 5, to move radially inwards and outwards when the cam guide 8 is rotated about the axis of rotation 11 (with respect to the axis of rotation 11), and the nozzles 4 to rotate about their nozzle axes of rotation 26. The radial height and radial depth of the waveform of the groove 9 determine a rotation angle of the nozzles 4 about the nozzle rotation axes 26 shown in Figs. 4 and 5. A groove width 28 of the groove 9 corresponds (essentially) to a diameter 30 of the guide sections 27 shown in Fig. 5.
