Description

The invention relates to a shower device with a tube, which has a water supply for at least one shower and is to be attached to a specific mounting location, such as a wall.

Wall bars for attaching hand showers or overhead showers have long been known. They are usually designed as a tube. Also known are profiles along the brackets for overhead showers or hand shower can be moved. While the profiles are bolted directly to the wall in many cases, the wall bars are usually mounted with a certain distance in front of the wall, so that the holders for overhead showers or hand shower can still be adjusted and rotated.

There are also known water-leading wall bars, which are usually screwed in a certain fixed position on the wall.

It is a device known (DE 103 05 786), in which a water-conducting tube is arcuate, so that it has two parallel sections. Side showers can be installed along the pipe. Such a shower arrangement can be mounted on two walls, in which case the angle between the wall and the longitudinal axis of the pipe can be different depending on the location of the sanitary fitting.

The invention is based on the object to provide a shower device with a pipe, in particular a water-carrying pipe, which can be attached to an attachment point, that the orientation of the tube can be arbitrary about its axis. In particular, it should be possible to use the plumbing fixture connected to the house installation as a reference point for the installation of the shower device.

To solve this problem, the invention proposes a shower device with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.

The attachment of the tube thus takes place at a separation point, where two sections of the tube are interconnected. The separation point between the two sections of the tube is designed so that the two tube ends can be aligned axially with the aid of the alignment device, so that the optical shape of the tube is maintained as a continuous element. At the point of separation, a sleeve is arranged, which surrounds the separation point and this is rotatable relative to. The sleeve is axially secured against the pipe. The sleeve itself can be attached via a carrier at the mounting location, for example by means of a plate on a wall. The use of the term "mounting location" is intended to indicate that the attachment of the pipe can be made not only to the wall of a room but also to a support, shower stall wall or the like.

In a further development of the invention can be provided that the removal of at least one pipe section from the sleeve is prevented by a device.

Since at the point of separation between the two pipe sections and the sleeve is arranged, the alignment device may be formed so that it effects an alignment between a pipe section and the sleeve or preferably also between each pipe section and the sleeve.

However, it is also possible and is proposed by the invention that the alignment is effective directly between the two pipe sections, without the sleeve cooperates. It is also conceivable that the alignment acts between the pipe sections, but the sleeve cooperates supportive.

The axial fixing of the sleeve at the separation point can be done, for example, by an end face or a shoulder surface of the sleeve coming into contact with a corresponding mating face of one or both pipe sections.

According to the invention may be provided in a development that at least one pipe section has a projecting at its end out in diameter reduced pipe socket, which extends to at least in the sleeve. This reduced in its outer diameter pipe socket on the one hand forms a passage for the water supply and on the other hand a centering approach, which can serve both for aligning the pipe section relative to the sleeve and for axially securing the sleeve. It thus forms part of both the alignment device and the fixing device.

It is conceivable that both pipe sections have such a pipe socket, so that each pipe section is centered or aligned with respect to the sleeve.

It has already been mentioned that the axial fixing of the sleeve at the point of separation or vice versa of the pipe sections on the sleeve can be effected by the abutment of axial end faces or shoulder surfaces.

However, the invention also proposes that the pipe socket may have a circumferential groove into which engages an inner projection of the sleeve with little play. This projection can be formed for example by a pin or the front end of a screw. Since the groove rotates, the sleeve can be rotated around the entire circumference. At the same time the concern of the lateral surfaces of the screw or bolt on the walls of the groove forms the desired safeguard against removal.

It is also conceivable that the groove does not completely revolve, but extends only over such an arc angle that the desired adjustment is given.

The pipe socket may be a separate element, which is firmly connected to the pipe section from which protrudes out, for example, soldered.

In a further development of the invention can be provided that only on a pipe section such a pipe socket is attached, which extends through the sleeve through to the other pipe section. This reduces the production costs, since at a separation point only at one of the two pipe sections such a pipe socket must be soldered.

If the pipe is a water-conducting pipe, according to the invention, in a further development, the pipe socket can be sealed against the socket and, if it extends into the other pipe section, also against this pipe section.

In a further development of the invention can be provided that the sleeve merges with its surface flush in the surface of the two pipe sections. Only at the point where the sleeve is connected to the fastening device, so for example on the rear side facing the wall, the surface of the sleeve deviates from an extension of the surface of the two pipe sections. The user thus sees a continuous tube without perceiving the sleeve.

According to the invention, the pipe sections may also be pipe sections with an additional internal water supply. In this case, at the point of separation, there must also be a connection possibility for the inner line through the sleeve and optionally through the pipe socket. This can be achieved by protruding from the ends of both pipe sections lines, one of which is used for insertion of the line end of the other pipe section.

According to the invention may be provided in a development that the shower device is used together with a sanitary fitting in such a way that at least one pipe section of the shower device is attached to the mixing fitting, in a similar manner rotatable as at the separation point with the sleeve. The rotation is thus usually done around a vertical axis.

In a further development it can be provided that the attachment of the pipe section to the mixing fitting is designed such that the pipe section is connected to the mixing water outlet of the sanitary fitting.

It may be provided according to the invention that the mixed water outlet has a double water supply, which is then connected to the shower also having a double water supply.

It can be inventively provided that the valve has a switching device for selectively controlling one of the two water channels or both water channels.

Through the two water channels, it is possible, as already mentioned, to control the side showers and a possible overhead shower separately. Of course, it is also conceivable to use other shower facilities so. For example, two types of side showerheads could be controlled separately.

In a further development can be provided that the valve additionally has a connection for a hand shower. This connection can be arranged on the fitting itself, so work independently of the shower facilities with the pipes.

According to the invention, the fitting can form an attachment point for the pipe of the shower device.

FIG. 1 shows an application for the solution proposed by the invention. Here is a shower facility to see that has a mixing valve 1. The mixing fitting supplies an overhead shower 2 and a variety of side shower 3 with water. For this purpose, a pipe leads from the mixing fitting both upwards and downwards. The upwardly leading tube initially contains a rectilinear pipe section 4, which then merges into a pipe section 5 extending over half a circular arc. At the end of this pipe section 5 then begins a next pipe section 6, which is again rectilinear as the pipe section 4. Below the mixing valve 1, a further pipe section 7 is present, which is again rectilinear. Even if the pipe sections do not go through the mixing fitting 1, this impression is created. The various pipe sections must now be mounted on walls, including several mounting arrangements are present, which have a plate 8 which can be screwed to a wall. Since both the overhead shower 2 and the side showers 3 are supplied with water from the mixing fitting 1 and the overhead shower 2 should also be supplied separately with water, the part of the pipe sections leading from the mixing fitting 1 to the overhead shower 2 is provided with an inner one Provided water supply.

The side showers 3 are oriented in such a way that they release water towards the inside, that is towards each other. This is because the pipe sections lie in one plane.

Figure 2 shows in a schematic plan view how a shower device of Figure 1 between two walls 10, 11 can be attached. The mixing fitting 1 is screwed to the one wall 10. The mixing fitting 1 facing away from the straight pipe section 6 and is attached to the other wall 11. The plate 8, already mentioned was, so it is screwed to the wall 11. In the example shown, the distance of the mixing fitting from the corner 12 between the two walls 10 and 11 is identical to the distance between the mounting plate 8 of the pipe section 6 from this corner 12. The tube of the pipe section 6 must therefore be oriented relative to the plate so that the side showers against the surface of the wall 11 at an angle of 45 degrees. However, it is readily apparent that the mentioned distances between the corner 12 and the mixing valve on the one hand and the plate 8 on the other hand do not have to be identical. In this case, the side showers 3 of the pipe section 6 and the side showers 3 of the pipe sections 4 and 7 should be able to be oriented differently with respect to the respective wall 10, 11.

In the example shown in Figure 3, the pipe sections must be oriented so that the side showers radiate at a right angle to the two walls.

This possibility of attaching the water-carrying pipe at different angles relative to the point at which the pipe is mounted, is made possible by the manner of attachment, which will now be explained in more detail with reference to Figure 4. FIG. 4 shows in a longitudinal section the manner of attachment of the tube to a wall, for example the wall 10.

The tube of the shower device is constructed from several pipe sections, which each form a separation point between each other. Figure 4 shows the separation point between the pipe section 4 and the pipe section 5 in Figure 1. In the end portion of the upper pipe section 5, an inner pipe socket 15 is inserted and soldered. This pipe socket 15 protrudes clearly from the end face 16 of the upper pipe section 5 out. The pipe socket 15 has in its protruding from the pipe 5 out section a circumferential groove 17.

On the pipe socket 15, a sleeve 18 is pushed, the inner diameter of the inner diameter of the two pipe sections 5,4 and the outer diameter also corresponds to the outer diameter of the two pipe sections 5,4. On one side of the sleeve 18, a radial connection piece 19 is integrally formed, in the hollow interior of a screw 20 is housed. The screw is screwed with its screw shank 21 in a threaded bore 22 of the nozzle 19 and protrudes with its free end into the groove 17. The nozzle 19 is then placed on a provided with a wedge surface 23 approach 24 of the plate 8, and fixed there by means of a grub screw 25. The plate 8 and the connection between the nozzle 19 and the plate 8 is covered by a rosette 28.

By engaging the front end of the screw 20 in the groove 17, the sleeve 18 is axially fixed to the pipe section 5. To seal between the inner pipe socket 15 and the inside of the sleeve 18 are used seals 29 which are inserted in grooves.

The pipe socket 15 is dimensioned so that its protruding from the upper pipe section 5 part is significantly longer than the length of the sleeve 18 so that it extends through them into the interior of the lower pipe section 4. Opposite this lower pipe section 4, the pipe socket 15 is also sealed by seals 29.

The pipe socket 15 causes on the one hand an alignment of the two pipe sections 5, 4 in mutual axial extension and on the other hand, a possibility for rotatable axially secured mounting of the sleeve 18. When the sleeve 18 is screwed to the illustrated and described device on the wall 10, the pipe sections 4 are twisted around the axis of the specified sleeve. A Orientation of the jet direction of the side showers is still possible.

When mounted sleeve 18 of the upper tube section 5 is secured against removal. The lower pipe section 4 leads in the case shown in the mixing valve 1 and is secured there against removal.

The separation point, which is shown in Figure 4, includes the aforementioned possibility to bring with the help of an inner water supply water to the overhead shower 2, regardless of the operation of the side showers. For this purpose, an adapter 31 is placed on an inner pipe 30 in the pipe section 4, which forms a section for threading in its end region 32. The end portion of the adapter protrudes beyond the front end of the pipe section 4.

From the other pipe section 5 also protrudes a line 33 beyond the front end 34 of the pipe socket 15 also. The end of this line 33 is provided with a sealing adapter 35 which can be inserted into the threading section of the adapter 31. When assembling the two pipe sections and the sleeve 18 then pushes this adapter forward until it reaches the position shown.

The mounting arrangement on the opposite side, namely between the pipe section 5 and the straight pipe section 6 is done in the same way.

The attachment of the two lower ends of the pipe sections 7 and 8 is done with the help of the same wall support, in which case the sleeve 18 may be closed down, and the pipe socket 15 only needs to reach into the sleeve 18 itself.

This is shown in FIG. The pipe socket 15 is closed in this example below by a plug or a wall. It is soldered in the same way in the lower end of the pipe section 7 as in the wall support shown in Figure 4, so that it protrudes from the lower end of the pipe section 7. The sleeve 18 is closed in this case below. The seals 29 are further required to seal the rotatable tube section 7 relative to the sleeve 18. FIG. 6 shows the attachment of an overhead shower 2 at the upper vertex of the pipe bend 5.

The pipe bend is divided into two parts and separated in the middle. In the middle, a branch element 40 is inserted between the two parts of the pipe bend 5, which is soldered to the two parts of the pipe bend 5. In the region of both ends, the branch element 40 contains a section with a reduced diameter, so that a contact shoulder 41 for the tube 5 is formed there. From the branching element 40 leads at right angles to the pipe axis, a branch 42 addition, to which the above-mentioned overhead shower 2 is attached. The attachment of the overhead shower 2 to the branch element 40 can be done by means of a ball joint.

Details of the branching element are shown in FIGS. 7 and 8. Here, Figure 7 shows an end view of the branch element 40 from the left in Figure 6. In the middle of the branch element 40 is a passage 43 can be seen, in which the tube 33 is used for internal water supply and soldered. From this passage, the water passes through a bore 44 extending transversely thereto to the overhead shower 2.

Radially outside the passage 43, a total of six channels 45 are bored, which pass through the branch element 40 in the axial direction. Through these channels 45, see also Figure 8, flows in the pipe 5 outside the line 33 flowing water to the side showers 3 on the opposite side.

FIG. 8 again shows the branch element 40 on an enlarged scale, the section being laid through another plane so that it leads through one of the channels 45.

With the shower device proposed by the invention, it is firstly possible to mount a shower device between two walls so that any angle between the plane in which the tube is located, and the mounting walls are possible. This was illustrated in FIGS. 2 and 3 by two examples. On the other hand, there are also cases where it is not possible to arrange the shower device so that the overhead shower is located directly above the center of the shower tray. In these cases, the overhead shower can be adjusted with a ball joint, so that it is directed to the center of the shower tray. Here, the side showers of the vertically extending sections 4, 6, 7 can now be directed by rotating the corresponding pipe section in the middle of the shower cubicle.

Moreover, it is also possible to make a pipe so that the upper pipe bend 5 is not in a plane. For example, it is conceivable to arrange the rectilinear extending portions immediately in front of a single wall and to deform the raw sheet 5 out of the surface of the wall to thereby position the overhead shower over a shower tray standing in front of the wall. In this case, the straight running sections with the side showers 3 can also be rotated in order to direct the emission direction of the side showers 3 into the center of the shower cubicle.

FIG. 9 again shows the mixing fitting 1 already indicated in FIG. 1 on a larger scale. In the mixing valve 1 is a multi-way valve accommodated with a control element 50. With the help of the control element 50, the water from the domestic installation, which is mixed within the mixing valve, are passed into the pipe sections 4 and 7. Depending on the position of the control element, it can also be directed into the inner water duct 33, which leads to the overhead shower. In addition, the mixing valve has a connection 51 to which a hand shower can be connected via a hose. This connection can also be controlled by means of the operating element 50. Both the pipe section 4 connected to the top of the mixing fitting and the pipe section 7 connected to the underside can be rotated around its own longitudinal axis.
