Description

The invention relates to a swivel shower according to the preamble of claim 1. Such swivel showers can be used, for example, as wall-mounted or ceiling-mounted sanitary swivel showers, such as swiveling, ceiling-mounted overhead showers and as swiveling, wall-mounted side showers in shower rooms.

These swivel showers have a swivel body with a shower outlet that is held pivotably on a base body, the swivel body being pivotable between two end positions, one of which functions as a rest position and the other as an operating position. In the rest position, the swivel shower is inactive, i.e. no shower fluid escapes from the shower outlet. In the operating position, the swivel body is in its active shower position, in which the shower fluid supplied via a shower fluid inlet leaves the shower outlet as a corresponding shower jet.

For driven pivoting of the pivoting body, a pivoting drive is used which comprises a slide piston which can be acted upon by a fluid pressure of the shower fluid and which is arranged in a translationally movable manner corresponding to the two pivoting body end positions between a first and a second piston end position. The shower fluid inlet can be on the main body or on the swivel body, for example.

A swivel shower of the type mentioned is in the patent EP 1 947 251 B1 disclosed. The swivel shower there is designed as a sanitary shower shower for wall and / or ceiling mounting with a flat outer surface. The flat outside of the swivel shower forms the visible side of the shower, ie that side which is visible to the user in the mounted state of the swivel shower or which faces him. The swivel body is formed by a shower bracket that carries one or more shower units. In the active operating position, the shower units protrude beyond the outside of the shower. Pipe sections of a shower fluid supply serve as pivot axes of the shower support, and the slide piston of the pivot drive that can be acted upon by the fluid pressure of the shower fluid supplied is also part of the Pivot axes arranged perpendicular translation direction. In one embodiment shown, it presses with a pressure pin at a lateral distance from the pivot axes against an inside of the shower support and swivels it by approx. 15 ° from a rest position, in which its shower outlet side runs parallel to the flat outside of the swivel shower, into an inclined operating position . Alternatively, the use of a translation with a deflection is proposed in order to be able to swivel the shower support through 180 ° if necessary, so that in the rest position a smooth side faces outwards and the visible side of the swivel shower accordingly appears to be closed.

Further swivel showers of the type mentioned are in the form of headlamp washing devices in the laid-open documents DE 41 30 892 A1 and DE 199 45 854 A1 disclosed, where the slide piston is arranged there with a translation direction perpendicular to the pivot axis and the pivot drive includes a transmission element in the form of a lever joint in order to convert the translational movement of the slide piston into the pivot movement of the pivot body.

The technical problem underlying the invention is the provision of a swivel shower of the type mentioned at the beginning with improved functionalities and properties compared to the above-mentioned prior art.

The invention solves this problem by providing a swivel shower with the features of claim 1. Advantageous, optionally realizable developments of the invention are specified in the subclaims.

According to a first aspect of the invention, the slide piston of the swivel drive for the swivel body is arranged with a translational direction component parallel to the swivel axis. This means that the translational direction of the slide piston is parallel to the pivot axis or in any case has a non-zero component parallel to the pivot axis, ie the translational direction of the slide piston is not perpendicular to the pivot axis. This arrangement of the spool can form functional advantages for the swivel drive and favor a compact design of the swivel shower.

According to a further aspect of the invention, the pivot drive contains a transmission element in the form of a link guide between the slide piston and the pivot body in order to transfer the translational movement of the slide piston into a pivot movement of the pivot body. Such a transmission element can offer functional advantages and enables a favorable conversion of the linear translational movement of the slide piston into the rotary movement carried out by the pivoting body during pivoting.

In a further development of the invention, the link guide comprises a first guide part with a slide track and a second guide part with a slide cam interacting with the slide track. Of these two guide parts, one guide part is arranged immovably on the base body, while the other guide part is arranged so that it can move in translation with the translational movement of the slide piston and is rotationally coupled to the swivel body. This link guide enables a functionally reliable and stable transfer of the translational movement of the slide piston into the rotary or pivoting movement of the pivoting body, and the pivoting shower can be built relatively compact if required.

In one embodiment of the invention, that guide part which is arranged to be movable in translation with the translational movement of the slide piston and is rotatably coupled to the swivel body contains a driver sleeve which interacts with an end face of the slide piston. This driver sleeve can be moved in a translatory manner by the slide piston and rotated at the same time via the link guide, whereby the swivel body rotatably coupled to it is pivoted.

In a further development of the invention, the slide piston is guided in a translationally movable manner on a pivot shaft sleeve defining the pivot axis. In this way, the pivot shaft sleeve can provide both a pivot shaft for pivoting the pivot body and a guide for the translationally moved slide piston. Additionally or alternatively, the slide piston can be pushed telescopically onto the swivel shaft sleeve or pushed into it.

In a further development of the invention, the swivel shower has an elastic piston return element which biases the slide piston into its first piston end position. The elastic piston return element can, for example, be a compression or tension spring, which is supported on the one hand on the base body and on the other hand on the slide piston or is connected to the same at one spring end. In corresponding embodiments, the tension / compression spring can be pushed coaxially onto the pivot shaft sleeve and thereby held or guided on it. By pretensioning the slide piston into its first piston end position, the swivel body is pretensioned accordingly into its rest position. If no shower fluid is supplied or the shower fluid supply is switched off or blocked, the swivel body in corresponding embodiments of the invention assumes this rest position which is stabilized by the action of the elastic piston return element. When the shower fluid supply is opened, the fluid pressure of the shower fluid supplied then presses the slide piston against the action of the elastic piston return element in the direction of its second piston end position, whereby the swivel body is pivoted into its active operating position.

In a further development of the invention, the swivel shower has a locking element with which the swivel body can be locked in the second swivel body end position. As a result, the swivel body can be held in its second swivel body end position, e.g. for maintenance or cleaning work, regardless of whether there is fluid pressure from the shower fluid supplied or the shower fluid supply is shut off. This is particularly useful for versions of the swivel shower in which the swivel body is swiveled away from the visible side of the swivel shower in the rest position or is not freely accessible to the user from the outside.

In a further development of the invention, the shower outlet has a jet outlet plate with at least one jet outlet nozzle, the nozzle longitudinal axis of which forms an acute angle, ie an angle greater than 0 ° and smaller than 90 °, with the jet outlet plate. The nozzle longitudinal axis defines, as usual, a main jet direction of a shower jet emerging from the jet outlet nozzle or a shower jet formed by several such jet outlet nozzles. This means that in this case the shower jet emerges at an acute angle of its main jet direction to the jet outlet plate. In this way, for example, the shower jet can be added to one Visible side of the swivel shower can be emitted in the vertical main jet direction if or although the jet outlet plate in the active operating position of the swivel body is not oriented parallel, but rather obliquely to the visible side of the swivel shower.

In a further development of the invention, the shower outlet is pivoted away from a visible side of the pivoting shower in the rest position of the pivoting body, and a pivoting angle stroke from the first to the second pivoting body end position is at most 90 °. As already explained above, the visible side here means the side of the swivel shower that is visible to the user in the assembled state of the swivel shower or that faces him when used as intended. In the case of a wall-mounted or ceiling-mounted sanitary shower, the visible side is consequently typically a shower front side that faces the user located in front of or below the swivel shower. This measure can offer functional and design advantages. In this inactive position of the swivel body, the shower outlet can be swiveled away invisibly for the user, e.g. by being swiveled into the base body. Nevertheless, a swivel angle stroke of at most 90 ° is sufficient to swivel the swivel body into its active shower operating position, in which the swivel shower emits the desired shower jet via its shower outlet, for which the shower outlet is typically visible to the user on the visible side of the swivel shower. Depending on the requirements and application, the swivel angle stroke of the swivel body is also only a maximum of 50 °, e.g. approx. 45 ° or less. As is clear to the person skilled in the art, the above aspects of the invention are not necessarily functionally related and can therefore be implemented individually or jointly or in any combination in corresponding embodiments.

In one embodiment of the invention, the swivel body is formed by a cuboid shower cartridge which has the shower outlet on one of its cuboid sides and a top surface on an adjacent cuboid side that is parallel to the visible side of the swivel shower in the first end position of the swivel body. Such a swivel body can be produced with relatively little effort and can be advantageous in terms of design and function. In the inactive rest position of the swivel body, its top surface can be seen on the visible side of the swivel shower, while the shower outlet can be hidden from view for the user. The top surface can if desired, for example, form a substantially flush finish with an adjacent surface of the swivel shower or its base body, and / or the top surface can have a surface texture that is essentially uniform to an adjacent surface of the swivel shower, so that the swivel body is harmonious in this rest position fits into an inconspicuous overall picture of the swivel shower on its visible side. Only when the cuboid shower cartridge forming the swivel body is swiveled into its active operating position does its cuboid side containing the shower outlet appear on the visible side of the swivel shower, and the desired shower jet is then emitted via the shower outlet.

In a development of the invention, the swivel shower includes a shut-off valve which is arranged in a fluid flow path between the shower fluid inlet and the shower outlet and which closes and releases the fluid flow path depending on a swivel position of the swivel body. It completely blocks the fluid flow path in the first pivoting body end position and completely releases it in the second pivoting body end position. This has the advantage that no shower fluid can escape from the shower outlet when the swivel body is in the inactive rest position. On the other hand, the shut-off valve completely releases the shower fluid for active shower operation when the swivel body is in the operating position. The shut-off and release functionality of the shut-off valve is advantageously controlled by the pivot position of the pivot body, which automatically ensures that the shut-off valve provides the desired valve function in the respective pivot body end position.

In one embodiment of the invention, the shut-off valve has a switching hysteresis through which it begins to release the fluid flow path when the swivel body is pivoted from the first swivel body end position in the direction of the second swivel body end position than it does when the swivel body is swiveled out of the second swivel body end position Shuts off completely in the direction of the first swivel body end position. In other words, when the swivel body is pivoted from the rest position, shower fluid begins to emerge from the shower outlet only after a predetermined release pivot angle, since the shower fluid supply remains blocked by the shut-off valve until then. If, after active shower operation, the swivel body swivels back from its operating position to its rest position, the shut-off valve only completely blocks the shower fluid supply to the shower outlet at a shut-off swivel angle that is closer to the first swivel body end position than the release swivel angle. Shower fluid can therefore exit the shower outlet for a little longer before the shut-off valve completely shuts off the shower fluid supply to the shower outlet and the swivel body reaches its rest position. This can be advantageous for corresponding applications.

The ones in the Figs. 1 to 8 The swivel shower shown is suitable, for example, as a sanitary swivel overhead shower for ceiling mounting or as a sanitary swivel side shower for wall mounting in shower rooms. It contains a base body 1 and a swivel body 2 which has a shower outlet 3. The swivel body 2 is held on the base body 1 so that it can pivot about a swivel axis Sa between a first swivel body end position Rp, which forms a shower inactive rest position, and a second swivel body end position Bp, which forms a shower active operating position. A shower fluid inlet 4 is used to supply a shower fluid, such as shower water. In the exemplary embodiment shown, the shower fluid inlet 4 is formed by a fluid inlet-side connecting pipe piece 4a which is formed on the base body 1 or is connected to it. In alternative embodiments, the shower fluid inlet 4 is implemented in a different conventional manner and / or is formed on the swivel body 2 or is connected to it.

A swivel drive 5 is used for driven swiveling of the swivel body 2, the swivel drive 5 having a slide piston 5a that can be acted upon by a fluid pressure of the shower fluid supplied. The slide piston 5a is arranged such that it can move in translation between a first piston end position K1 corresponding to the first pivoting body end position Rp and a second piston end position K2 corresponding to the second pivoting body end position Bp. The translational movement of the slide piston 5a, i.e. its linear displacement movement, takes place in a translational direction TR which has a parallel translational direction component TRp other than zero. As is usual for slide pistons, the slide piston translation direction TR is parallel to an axial direction or longitudinal axis SL of the slide piston 5a. In the example shown, the slide piston translation direction TR is parallel to the pivot axis Sa. In alternative versions, the translation direction TR of the slide piston 5a has, in addition to the direction component TRp parallel to the pivot axis Sa, a translation direction component that is different from zero and is perpendicular to the pivot axis Sa, i.e. in this case the The direction of displacement TR of the slide piston 5a is oriented obliquely to the pivot axis Sa of the pivot body 2.

In the example shown, one in the Figures 3 and 4 lower side of the swivel shower a front side or visible side FS, by which, as already said, that side of the swivel shower is to be understood, which the user in the mounted state of the swivel shower, for example after mounting on a ceiling or wall area of a shower room, facing or for visible side is to be understood. How further for example from the Figures 3 and 4 As can be seen, the shower outlet 3 is swiveled away from the visible side FS of the swivel shower in the rest position Rp of the swivel body 2. In order to move the swivel body 2 from its rest position Rp as the first swivel body end position into the shower-active operating position Bp as the second swivel body end position, it needs to be swiveled by at most 90 °. In the exemplary embodiment shown, the pivot angle stroke, that is to say a pivot angle α _H between the two pivot body end positions Rp, Bp, is approximately 45 °. In alternative embodiments, this swivel angle stroke α _{H can} have any other value, preferably in the range between 0 ° and 90 °.

In the exemplary embodiment shown, the swivel body 2 is formed by a cuboid shower cartridge 2a which has the shower outlet 3 on one of its cuboid sides and a top surface 6 on an adjacent cuboid side. In the first swivel body end position Rp, the top surface 6 is parallel to the visible side FS of the swivel shower, ie a plane E _{6 of} the top surface 6 is parallel to a plane E _{FS of} the visible side FS. As a result, only this top surface 6 of the swivel body 2 appears optically for the user when the swivel shower is not in active shower mode and the swivel body 2 therefore assumes its rest position Rp. In this case, the shower outlet 3 is swiveled into the frame-shaped base body 1, invisible to the user. Depending on what is desired or required, the swivel shower can terminate with this top surface 6 essentially flush with an adjoining surface of the swivel shower and / or with an adjoining ceiling or wall area of a shower room. Additionally or alternatively, the top surface can have a surface quality that is essentially uniform to an adjacent surface area of the swivel shower and / or a ceiling or wall of a shower room, so that the swivel body 2 in its rest position Rp blends harmoniously and unobtrusively into the overall picture of the swivel shower on its visible side FS inserts.

In alternative embodiments, the swivel body 2 has a shape deviating from a cuboid shape, e.g. a triangular shape or semicircular shape in cross section. The invention further comprises embodiments in which the swivel body 2 is cuboid, but does not have a top surface in the manner of the top surface 6. In addition, in corresponding alternative embodiments of the invention, the side of the swivel body 2 having the shower outlet 3 can lie wholly or partially on the visible side FS of the swivel shower when the swivel body 2 is in its inactive rest position Rp.

In the exemplary embodiment shown, the shower outlet 3 has a jet outlet plate 3a with at least one jet outlet nozzle 7, the nozzle longitudinal axis Ld of which forms an acute angle β with the jet outlet plate 3a. As shown, the jet outlet plate 3a preferably includes a plurality of such jet outlet nozzles 7 with longitudinal nozzle axes Ld parallel to one another 3a extend through and preferably consist of an elastomer material, or simply be formed by outlet nozzle openings made in the jet outlet plate 3a. In the active shower mode, the jet outlet nozzles 7 generate a shower jet with a main jet direction parallel to the nozzle longitudinal axes Ld, ie the shower fluid leaves the shower with this preferred direction parallel to the nozzle longitudinal axes Ld, which can also be understood as a longitudinal axis of the shower jet.

Due to the inclination of the nozzle longitudinal axes Ld with respect to the jet outlet plate 3a by the angle β, a shower jet can be emitted from the shower outlet 3 in the embodiment shown, the main jet direction of which runs perpendicular or approximately perpendicular to the visible side FS of the shower, although the jet outlet plate 3a is perpendicular to the pivoted rest position Rp Visible side FS of the shower is oriented and the shower cartridge 2a is swiveled only by, for example, 45 ° to 50 ° into the active operating position Bp. The angular position of the main jet direction of the shower jet relative to the visible side FS of the shower results from the addition of the swivel angle stroke α _H and the inclined angle 90 ° -β of the nozzle longitudinal axes Ld with respect to a plane normal of the jet outlet plate 3a and can thus be determined by a suitable choice of the angles α _H and β any desired value can be set, for example in the range from 70 ° to 90 °.

In order to apply fluid pressure to the slide piston 5a, the swivel shower has a piston chamber 8 which is in fluid connection with the shower fluid inlet 4 and which is connected via a connection channel 9 to the connection pipe section 4a on the fluid inlet side. In the example shown, the slide piston 5a is designed as a hollow cylindrical component with an end face that is closed towards the piston chamber 8 and an end face that is open opposite.

With its open end face, the slide piston 5a can be pushed onto a pivot shaft sleeve 10, surrounding it coaxially. The pivot shaft sleeve 10 is formed on the base body 1 or attached to it and, with its longitudinal center axis, defines the pivot axis Sa of the pivot body 2 pivoted relative to the base body 1. For this purpose, the pivot body 2 is pivotably held or mounted on the pivot shaft sleeve 10. At the same time, the pivot shaft sleeve 10 in FIG this embodiment as a guide for the translationally movable slide piston 5a and / or as a telescopically cooperating component with the slide piston 5a. In the embodiment shown, the pivot shaft sleeve 10 is formed on a pivot axis component 22 which also has a fastening flange 23 protruding radially at one end of the pivot shaft sleeve 10, on which two retaining bolt stubs 24 are arranged protruding laterally at a distance from one another, as in particular from Fig. 8 evident. With the retaining bolt stubs 24, the pivot axis component 22 can be hooked into corresponding recesses 25 of a cross member 26 of the base body 1 and thereby held on the frame of the base body 1.

In the exemplary embodiment shown, the swivel drive 5 also includes a transmission element for transferring the translational movement of the slide piston 5a into the swivel movement of the swivel body 2, the transmission element being implemented in the form of a link guide 5b. In an advantageous embodiment shown, the link guide 5b comprises a first guide part 11, which contains a slide track 11a, and a second guide part 12, which has a slide cam 12a which interacts with the slide track 11a. Of the two guide parts 11, 12, one guide part is arranged immovably on the base body 1, while the other guide part is arranged so as to be movable in translation with the translational movement of the slide piston 5a and is rotationally coupled to the swivel body 2. For example, as shown, the first guide part 11 with the slide track 11a can be arranged in a stationary manner on the base body 1, while the second guide part 12 with the slide cam 12a can be moved in translation with the translational movement of the slide piston 5a and is rotatably coupled to the swivel body 2.

In an exemplary implementation, the second guide part 12 contains a driver sleeve 12 ′ that interacts with an end face of the slide piston 5a. The guide part 11 containing the link path 11a is advantageously formed in the example shown by the pivot shaft sleeve 10; in alternative embodiments of the invention, the guide part 11 forms a preferably sleeve-shaped component that is different from the pivot shaft sleeve 10 and is formed on the base body 1 or attached to it in a stationary manner . The slide track 11a is in the example shown, in particular from Fig. 8 can be seen as a winding path with a combined axial direction and the circumferential direction component is introduced into the sleeve-shaped guide part 11. The link cam 12a protrudes radially inward from the driver sleeve 12 'and engages in the link track 11a. This is over Fig. 7 can be seen, in which a part of the surrounding components is shown cut out like a window for this purpose.

The driver sleeve 12 'axially adjoins the open end of the slide piston 5a and has an approximately equal diameter. As a result, when the slide piston 5a is displaced from its first piston end position K1 in the direction of its second piston end position K2 due to the fluid pressure of the shower fluid supplied, the driver sleeve 12 'is axially moved along with it by the slide piston 5a. Due to the interaction of the link cam 12a with the stationary link track 11a, the axial movement of the driver sleeve 12 'results in a simultaneous rotation of the driver sleeve 12'. Because of the rotational coupling of the swivel body 2 with the driver sleeve 12 ′, this in turn causes the desired swiveling of the swivel body 2.

In the embodiment shown, the rotary coupling of the swivel body 2 with the driver sleeve 12 'is implemented as a non-rotatable connection, for which the driver sleeve 12' has one or more axially extending driver webs 12b that protrude radially from their outside and each engage in an associated axial groove 13a, which at the inside of a swivel body sleeve 13 is / are formed, which is formed in one piece on the swivel body 2 or is rotatably connected to the swivel body 2 as a separate component. A rotation of the driver sleeve 12 'thus results in a corresponding rotation of the swivel body sleeve 13 and thus of the entire swivel body 2. In alternative embodiments of the invention, the swivel body can be rotatably coupled to the driver sleeve via a conventional gear, with the desired step-up or step-down as required.

The swivel body sleeve 13, together with the swivel shaft sleeve 10 functioning as a hub for this purpose, serves as a swivel bearing for the swivel body 2 on the base body 1. For this purpose, the swivel body sleeve 13 is rotatably placed on the swivel shaft sleeve 10. The driver sleeve 12 'is received in an annular space 14 remaining between the pivot shaft sleeve 10 and the pivot body sleeve 13. In addition, the sleeve-shaped slide piston 5a can move with its Move open side into this annular space 14, where he pushes the driver sleeve 12 'in front of him.

In an advantageous embodiment, the swivel shower contains an elastic piston return element 15 which preloads the slide piston 5a into its first end position K1 and which in the example shown is formed by a helical compression spring 15a. In alternative embodiments, the elastic piston return element 15 can be formed as a tension spring or as a rubber-elastic element. In the exemplary embodiment shown, the helical compression spring 15a is received in the annular gap 14, it being supported on the one hand on an annular shoulder of the pivot shaft sleeve 10 and on the other hand on the driver sleeve 12 '. In this way, the helical compression spring 15a presses the driver element 12 ′ and with it the slide piston 5a in the direction of the first piston end position K1, which corresponds to the rest position Rp of the swivel body 2.

Outside of the annular gap 14, the slide piston 5a is guided in a fluid-tight manner in a piston receiving cylinder 16, axially adjoining the pivot bearing of the pivot body 2 with the pivot shaft sleeve 10 and the pivot body sleeve 13. The piston receiving cylinder 16 is part of the base body 1, which is stationary with respect to the swivel body 2, and defines or delimits the piston space 8.

In the exemplary embodiment shown, the swivel body 2 and the base body 1 are designed, as shown, essentially symmetrically to a center plane ME of the swivel shower. This means that the swivel shower shown includes, among other things, two swivel bearings with a respective swivel shaft sleeve 10 and swivel body sleeve 13 and two swivel drives 5 with a respective slide piston 5a and link guide 5b of the type explained in an arrangement correspondingly mirror-symmetrical or symmetrical to the center plane ME.

Between the two slide pistons 5a or the piston receiving cylinders 16 there is a fluid guide component 17, which belongs to one part of the immobile base body 1 and to another part that is rotatable in comparison and belongs to the pivotable swivel body 2. The fluid guiding component 17 also has a structure that is essentially symmetrical to the center plane ME and includes, on each side, a section of a fluid flow path that extends between the shower fluid inlet 4 or the connecting pipe section 4a and the shower outlet 3 or a conventional fluid outlet chamber provided in the shower cartridge 2a upstream of the shower outlet 3 is formed, each with a shut-off valve 18. The two synchronously operating shut-off valves 18 block the fluid flow path depending on a pivoted position of the swivel body 2 or release it, completely closing off the fluid flow path in the rest position Rp of the pivoting body 2 and completely releasing it in the operating position Bp of the pivoting body 2.

In the example shown, the two shut-off valves 18 are each located in a connection channel 19 from the connection pipe section 4a to a connection piece 20, with which the relevant part of the fluid guide component 17 is rigidly connected to the swivel body 2, and each contain a valve ball 18a as a valve closing body and a valve control contour 18b on an outer circumference of a corresponding valve control sleeve. The respective valve control sleeve and consequently its valve control contour 18b pivot with the pivot body 2.

The valve control contour 18b is shaped in such a way that it faces the valve ball 18a with a shut-off contour when the pivot body 2 is in the rest position Rp, while it faces the valve ball 18a with a release contour when the pivot body 2 is in the operating position Bp. The shut-off contour is formed in a conventional manner such that the relevant fluid flow channel is completely shut off when the valve ball 18a interacts with the shut-off contour. The release contour is formed in such a way that the fluid channel in question is released, i.e. not completely shut off, i.e. fluid can flow past the valve ball 18a and the valve control contour 18b when the valve ball 18a interacts with the release contour. Such shut-off and release contours are known per se to the person skilled in the art and therefore do not require any further explanation here. Depending on the circumferential angle over which the shut-off contour or the release contour extend, the shut-off valve 18 blocks or releases the fluid flow path over a corresponding swivel angle of the swivel body 2.

In an advantageous optional embodiment variant, the respective shut-off valve 18 has a switching hysteresis, by means of which the fluid flow path when pivoting the pivoting body 2 from its rest position Rp in the direction of the operating position Bp release begins later when it completely blocks it when pivoting the swivel body 2 from the operating position Bp in the direction of the rest position Rp. As a result, when swiveling the swivel body 2 back into its rest position Rp, shower fluid can exit the shower outlet 3 for a little longer before the shut-off valve 18 then completely shuts off the shower fluid supply to the shower outlet 3 as soon as the swivel body 2 has reached a certain shut-off angle position in or before its rest position Rp. In contrast, when the swivel body 2 is pivoted out of its rest position Rp, shower fluid only exits the shower outlet 3 when the swivel body 2 has reached a release angular position that is further away from the rest position Rp by a differential angle corresponding to the switching hysteresis than the shut-off angle position. As a result, when the swivel body 2 is pivoted back into its rest position Rp, shower fluid that is pushed back from the respective piston chamber 8 via the connecting channel 9 can escape from the swivel shower, which avoids corresponding fluid pressure loads in the shower. For the respective shut-off valve, in particular one can also be used, as it is in the laid-open specification DE 10 2017 203 946 A1 and the parallel publication EP 3 372 315 A1 is revealed.

In an advantageous, optional embodiment variant, the swivel shower contains a locking element 21 with which the swivel body 2 can be locked in its operating position Bp and can be held in this way independently of the prevailing fluid pressure. The locking element 21 can, for example, be a conventional locking pin which can be moved from an inactive position into a locking position when the swivel body 2 is in the operating position Bp. In the locked position, the locking pin is supported on the one hand on the base body 1 and on the other hand on the swivel body 2 and thereby secures the swivel body 2 in this operating position Bp. By releasing the locking element 21, the swiveling back of the swivel body 2 from its operating position Bp can be released again. Such a locking of the swivel body 2 is useful, for example, for maintenance and repair work. For example, the jet outlet nozzles 7 can be in this operating position when the shower is turned off Bp of the swivel body 2, in which the jet outlet nozzles 7 are easily accessible.

From the above explanations on the structure of the swivel shower, its advantageous mode of operation is also clear. In the inactive operating state, no fluid is supplied to the swivel shower. The swivel shower is in the quasi fluid pressure-free state in which the respective slide piston 5a assumes its first end position K1 and is held in this position in a pretensioned manner by means of the elastic piston return element 15. Correspondingly, the swivel body 2 is in its rest position Rp. If the user activates the shower by activating the fluid supply, e.g. by opening a conventional fluid supply shut-off valve, not shown in the present case, upstream of the swivel shower, fluid passes through the inlet 4 into the connecting pipe section 4a and 4a from there on the one hand to the respective shut-off valve 18 and on the other hand into the respective piston chamber 8. The shut-off valve 18 is still in its shut-off position, so that no fluid is yet escaping from the shower head.

Due to the fluid pressure building up in the piston chamber 8, the respective slide piston 5a is advanced against the pretensioning force of the elastic piston return element 15, whereby it advances the driver sleeve 12 '. The driver sleeve 12 'is rotated at the same time due to the link guide 5b, which in turn rotates or pivots the swivel body 2 out of its rest position Rp accordingly. As soon as the swivel body 2 has reached its release angular position, the respective shut-off valve 18 opens the further fluid flow path into the swivel body 2 or to its shower outlet 3, whereupon the shower fluid emerges as desired from the shower outlet 3 as a shower jet. If the release angular position of the swivel body 2 does not yet correspond to its fully swiveled operating position Bp, the swivel body 2 swivels completely into the operating position Bp, since the fluid pressure in the piston chamber 8 advances the respective slide piston 5a until it reaches its corresponding end position K2.

To end the shower operation, the user turns off the fluid supply to the swivel shower. As a result, the fluid pressure in the respective piston chamber 8 drops, and the elastic restoring element 15 pushes the driver sleeve 12 'and with it the respective slide piston 5a back axially. At the same time, the driver sleeve 12 'rotates back again due to the link guide 5b, whereby the swivel body 2 pivots back accordingly. The respective shut-off valve 18 remains fully or at least partially open until the pivoting body 2 swings back into its shut-off angle position has reached. Until then, fluid that is pushed back from the two piston chambers 8 into the connecting pipe section 4a by the return movement of the slide pistons 5a can reach the shower outlet 3 via the two shut-off valves 18 and exit the shower. After the shut-off angle position has been reached, the shut-off valves 18 block the fluid flow path to the shower outlet 3, so that no more shower fluid emerges from it. If the swivel body 2 is not yet in its rest position Rp, it then swivels back completely into the rest position Rp, in that the slide pistons 5a are pushed back into their associated end position K1 by the elastic return elements 15 and the driver sleeves 12 'move back axially accordingly and rotate by means of the link guides 5b.

As the above-explained, shown and the above-explained further exemplary embodiments make clear, the invention provides a swivel shower with very advantageous properties and a relatively simple structure. The swivel shower can be used in particular in the sanitary area and here especially as a wall or ceiling-mounted side or overhead shower. It goes without saying, however, that the swivel shower can be used in the same way for non-sanitary applications wherever there is a need for a shower with a swiveling shower outlet.
