Thereby preventing: when the joint breaks, water can flow through the entire space or can escape when the flexible element is bent too strongly.

According to an advantageous embodiment of the invention, the flexible element is formed without an embedded line. This can be achieved, for example, in that the water stream wets the flexible element and in particular the intermediate section from the inside in the interior of the water spray device. The dimensions of the joint can be selected such that the contacting joint surfaces are designed as watertight sealing surfaces that correspond to one another. In this way, a liquid channel for throughflowing water can be produced in the interior of the water spray device, which extends from the inlet portion up to the outlet portion. It is thus possible to achieve that, even at high water pressures, no water is discharged from the liquid channel formed by the watertight joint.

According to an advantageous embodiment of the invention, at least two joints are formed in the flexible element. This enables the functionality of forming a bendable and flexible. For example, a plurality of joints is formed in the flexible element, so that an arc of more than 120 °, in particular more than 150 °, preferably more than 170 °, can be formed, in particular with a joint deflection angle of at least 45 °.

For example, the outer diameter of the hingedly connected intermediate sections can be less or not significantly greater than, in particular at most 20%, preferably at most 10%, greater than the outer diameter of the discharge section at the widest point. As small a construction size as possible can be achieved in this way. In particular, it is not provided that the water spray device has a water spray disk. The presence of a water spray disk having a larger size than the outlet according to the invention makes a flexible and compact functional construction of the water spray device difficult.

According to an advantageous embodiment of the invention, the intermediate section forming the flexible element and the embedded line are made of a metal-free material. It is thus possible to pass safety checks at airports if the water jet is carried along during travel. It is advantageous here that the elimination of metallic components makes it possible to save weight and thus to achieve easy transportability and/or to reduce production costs. For example, the intermediate section and/or the embedded pipe may be made of plastic. In particular, the flexible element may be made of rigid plastic and/or the inline pipe may be made of bendable plastic.

According to an advantageous embodiment of the invention, it is provided that the inlet and outlet are aligned with each other or at least oriented parallel to each other in the extended (gesttreckt) shape. This ensures that a water spray device can be formed with a package size that is reduced to a minimum, thereby facilitating handling when transporting in hand luggage while traveling. Thus, for example, a pin-shaped or rod-shaped water spray device can be formed in the transport position.

According to an advantageous embodiment of the invention, it is furthermore provided that the jet regulator is arranged on the outlet side and/or the flow regulator is arranged on the inlet side. The flow regulator is, for example, a flow restrictor. It is thus possible to unload the joint of the flexible element and to avoid any untightness in the ball joint.

According to an advantageous embodiment of the invention, it is provided that the jet regulator has a jet splitter which splits the inflowing water into a plurality of individual jets. The jet splitter is preferably arranged on the inflow side inside the housing of the jet regulator housing. The invention makes use of the fact that the throughflow water can be well formed in the jet regulator.

In accordance with an advantageous embodiment of the invention, it is additionally or alternatively provided that the jet regulator has a discharge structure with a plurality of outlet nozzles, wherein the outlet nozzles are arranged in such a way that a corresponding number of individual partial jets can be generated. For example, the outlet structure can be designed as a water jet, jet splitter. Preferably, the outlet structure is arranged or formed on the outlet side in the housing interior of the jet regulator housing as a closure on the outlet side thereof. In particular, the outlet structure can be designed such that the outer diameter of the individual outlet nozzles and the distance between the individual outlet nozzles are matched to one another, so that partial jets no longer recombine on the outflow side. A plurality of individual partial jets can thereby be generated which issue through the outlet nozzle. It is advantageous here that different jet types are possible which most people feel comfortable. For example, a finely metered and/or atomized distribution of the inflowing water can be produced by the outlet nozzle. It is thus possible to allow a shower jet consisting of a plurality of individual jets to be incident more than on individual, closely adjoining regions of the body. While a better distribution of the water and thus a gentle and comfortable shower jet is more achieved.

According to an advantageous embodiment of the invention, a preferably elastic sliding sleeve is provided in the water spray device, which sliding sleeve pushes onto the embedded line and presses it against the hose connector. The embedded line can thus be held with one end on the hose connector, in particular during pushing into the flexible element. The sliding sleeve can be made of plastic, for example.

According to an advantageous embodiment of the invention, provision is made in the water spray device for a sliding sleeve, such as the sliding sleeve already mentioned, to be provided, which, on account of the internal taper of the threaded part comprising the external thread, presses the embedded line with the toothing or the retaining rib onto the hose connector when the hose connector is pushed in. It is thus achieved that the entire water spray device construction is self-retaining in the plugged-together state.

According to an advantageous embodiment of the invention, it is additionally or alternatively provided that the flexible element has a thrust-back locking device for the embedded line, for example a barb which penetrates into the embedded line from the outside. The barbs prevent the embedded line from sliding in the axial direction, in particular when the hose connector is inserted from the outside into an already installed embedded line.

A preferred assembly sequence is therefore such that, at the end without the barb, the hose connection with the hose or the embedded line fitted is introduced until the free end of the hose or the embedded line is in the use position on the other side of the flexible element. In this position, the first end has been locked by the sliding sleeve. The second hose connector is now inserted from the open end, wherein the barb acts as a counter-thrust locking means and thus holds the embedded line in its position of use.

Detailed Description

Fig. 1 to 5 show different embodiments of the water spray device.

Fig. 1 shows a water spray device 1 according to the invention, which is connected to a water spray hose of a sanitary fitting, not shown in detail here.

The water jet device 1 has an inlet 2 and an outlet 3 into which a jet regulator 4 is inserted.

Between the inlet section 2 and the outlet section 3, a flexible element 5 is provided, which has at least two hingedly connected intermediate sections 7. The intermediate section 7 forms a segmented housing 16 (see fig. 4).

In the embodiment of the water jet device shown here, the flexible element 5 is formed with five intermediate sections 7, which are formed as ball joints 8. In other embodiments, there is another number of intermediate sections, for example more than five or less than five.

Fig. 1 to 3 show that the joint 8 has in each case one joint head 13, which is arranged in a joint socket 12 formed in a complementary manner in a pivotable manner in a pivot angle on all sides.

In the exemplary embodiment according to fig. 1, it can be seen that the pivot 8 has a pivot angle of at least 45 °, so that an arc of more than 120 ° can be formed by the flexible element 5.

Fig. 2 and 3 show that the inlet part 2 and the outlet part 3 are oriented parallel to one another in the stretched shape, whereby the water jet device can be formed with a package size reduced to a minimum.

It can furthermore be seen from the illustration according to fig. 3 that the flexible element 5 has a thrust-back locking device for the embedded line 6 in the form of a barb 20 on the held intermediate section, which barb penetrates into the embedded line 6 from the outside. The barbs 20 prevent the embedded conduits from sliding inwardly in the axial direction.

In order to fasten the embedded line 6 to the hose connector 19, in the water spray device 1 the embedded line 6 is surrounded at one end by a sliding sleeve 14 which interacts with an inner cone 18 (see fig. 3).

Fig. 5 shows another embodiment according to the invention. Components and functional units which are identical or similar in structure and/or function to the previous embodiments are denoted by the same reference numerals and are never described separately again. The embodiments of fig. 1 to 4 are therefore correspondingly suitable for fig. 5.

The exemplary embodiment according to fig. 5 differs at least from the exemplary embodiments according to fig. 1 to 4 in that, in the water spray device 1, the flexible element 5 is formed without an embedded line, so that the water flow wets the flexible element 5 and in particular the intermediate section 7 from the inside in the interior of the water spray device 1.
