Description

The present invention relates to a shower device, comprising at least one first water-carrying pipe, which has a jacket, and a shower head that is in fluid connection with the first pipe.

Shower devices are known from the prior art in which a pipe is used not only to hold the shower head and an additional hand shower if necessary, but also to direct the water to the shower head attached to the pipe. For this purpose, the pipe usually has a pipe section extending vertically along a wall and an approximately horizontally aligned pipe section to which the shower head is attached so that the user can stand under the shower head when showering. A switching device can be provided at the lower end of the pipe, via which the water can also be conducted to a hand shower which can be releasably attached to a separate holding device which can be displaced along the vertical section of the pipe. The known shower devices have the disadvantage that the height of the shower head and also its distance from the wall are predetermined by the dimensions of the pipe.

The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to provide a shower device in which the height of the shower head and / or its distance from the wall can be easily changed, if necessary, even after installation.

The object is achieved by a shower device with the features of the independent claim. Advantageous further developments of the shower device are specified in the dependent claims and in the description, with individual features of the advantageous further developments being able to be combined with one another in a technically meaningful way.

The object is achieved in particular by a shower device with the features mentioned at the outset, in which a second water-carrying pipe is provided, which is arranged at least in sections in the first pipe, and an axially extending recess is formed in the jacket of the first pipe, wherein A fixing device comprising at least one fixing element is provided on the second pipe, which extends from the section of the second pipe arranged in the first pipe through the recess, the second pipe being fixed in a fixing position of the fixing element in the first pipe and in a release position of the fixing element is movable to the first tube.

The basic idea of the invention therefore provides that the relative position of the second pipe in the first pipe can be changed simply by releasing the fixing device and shifting the second pipe in the released state (release position) in the first pipe, whereby on the position of the shower head can be changed easily. Since the fixation device is connected to the second tube, a user can Transfer the fixation element with one hand from the fixation position into the release position and move the second tube in the release position by means of the fixation device, so that the position of the shower head can be adjusted with just one hand. The formation of the recess in the jacket of the first tube also ensures that defined end stops are specified and thus the second tube cannot accidentally get out of the first tube.

The cross section of the first tube can have any design, such as round, oval, elliptical, or angular. The cross-sectional configuration of the first tube is usually constant along its extension. The second tube has at least one section arranged in the first tube with an external cross-sectional configuration that corresponds to the internal cross-sectional configuration of the first tube, wherein at least one O-ring can be disposed as a seal between the outer circumference of the second tube and the inner circumference of the first tube.

In its section arranged in the first tube, the second tube can have sections with a smaller outer diameter in order to reduce the friction with the first tube. For example, in the section arranged in the first tube, ribs formed at regular intervals can be formed on the outside of the second tube, which allow safe guidance during the movement of the second tube in the first tube, but cause only little friction.

The second tube extends in particular beyond the recess in the first tube into the first tube. The second pipe is preferably arranged with a piston-shaped section in a sealing manner in the water-carrying part of the first pipe.

The second pipe has, in particular on one end face, an opening through which the water passes from the first pipe into the second pipe. On the opposite side, the second pipe is usually closed, a fluid connection from the second pipe to the shower head being implemented in the radial direction of the second pipe through the jacket of the second pipe. The shower head is therefore in water-carrying fluid connection with the first pipe via the second pipe.

The recess is completely delimited by the jacket of the first tube, so that on the one hand the recess provides a guide for the fixing device and on the other hand forms a stop for the fixing device at its axial ends.

The fixing device has, in particular, a guide element which is connected through the recess in the jacket of the first tube to the section of the second tube arranged in the first tube, in particular releasably, after the section of the second tube has been inserted into the first tube. For example, this guide element can be screwed into a threaded bore formed in the second tube by means of an external thread. When the shower device is installed, the second pipe is inserted into the first pipe from an end opposite the water inlet of the first pipe, the fixing device then being connected to the second pipe through the recess.

The fixing device can in particular be designed in such a way that the second pipe is fixed in the first pipe via a non-positive and / or positive connection when the fixing element is in its fixing position.

To produce a force-fit connection, the fixing element can preferably be designed as a screw element (for example as a nut), the screw element in particular being screwable onto the guide element protruding through the recess and having an external thread. In the fixing position, the screw element can come into contact with the outer circumference of the first tube, so that the second tube is fixed in a non-positive manner. In this way, the fixing device can be brought into its fixing position at any point along the recess.

In this context, however, it can also be provided that a clamping element adapted in particular to the contour of the outer circumference of the first tube is formed between the screw element and the outer circumferential surface of the first tube and is pressed onto the first tube by the screw element in the fixing position. The clamping element can for example be sleeve-shaped and arranged between the screw element and the first tube on the guide element, the shape of the end face facing the first tube being adapted to the shape of the first tube.

For form-fitting fixing, the recess in the first tube can have a plurality of latching recesses, in particular transverse to its direction of extent and in the direction of extent, one behind the other, the fixing element engaging positively in at least one of the latching recesses in the fixing position. Preferably, on both sides of the recess along its direction of extent, opposing, preferably circular arc-shaped locking recesses are formed. In the fixing position, the fixing element is located within a latching recess or a pair of latching recesses, whereas in the release position the fixing element is out of the Locking recess is moved out. However, defined positions in which the fixing element can be brought into the fixing position are specified by the locking recesses.

For example, it can be provided that the fixing element can be moved between the fixing position and the release position by means of a threaded connection by means of a rotary movement. In particular, the guide element has an external thread on which the fixing element is rotatably arranged.

Alternatively, it can be provided that the fixing element can be moved linearly against a spring force from the fixing position into the release position. The fixing element, which is designed in particular as a sleeve, is pretensioned in the direction of the fixing position by the spring. A user can therefore pull the fixing element out of the locking recesses against the spring force and in this state move it along the recess together with the second tube, the fixing element automatically returning to the fixing position due to the spring.

The recess therefore has a width between the lateral latching recesses that is slightly larger than the width of the guide element, so that the guide element can be moved along the recess when the fixing element is in the release position.

In one embodiment it can be provided that the recess for adjusting the height of the shower head is arranged in a vertically oriented section of the first pipe. Correspondingly, the section of the second tube arranged in the first tube is also oriented vertically. In this embodiment, the second tube protrudes from the first tube, wherein the protruding portion of the second tube Shower head is attached. In this case, the second tube can have a vertically oriented section, which is at least partially arranged in the first tube, and a horizontally oriented section to which the shower head is attached. In this embodiment, the fixing device can be arranged in a lower section of the shower device that is easily accessible to the user, so that the user can easily adjust the height of the shower head by inserting and fixing the second pipe at different distances into the first pipe via the fixing device.

In a further embodiment it can be provided that the recess for adjusting the horizontal position of the shower head is arranged in a horizontally oriented section of the first pipe so that the section of the second pipe arranged in the first pipe is also horizontally oriented. In this way, in particular, the distance between the shower head and a wall can be adjusted.

In this embodiment it is preferred that the second tube is arranged completely in the first tube. In this case, the second tube can be introduced into the first tube from one end thereof, the end being closed by a corresponding cap. In this case, the second tube is only visible from the outside through the recess.

In particular in this embodiment it is provided that the shower head is connected to the first pipe via the second pipe and through the fixing device, for which purpose the component of the fixing device referred to above as the guide element forms a water guide element, which on the one hand with the second pipe and on the other hand with is connected to the shower head and thus leads the water from the second pipe to the shower head, the fixing element on the outside of the water guide element is movably mounted. The tubular water guide element is therefore screwed into the second tube, the fixing element explained in more detail above being movably arranged on the outside of the water guide element.

In the Figure 1 The shower device shown comprises a water-carrying first pipe 1 which has a jacket 2. A recess 5 extending along the direction of extent of the first tube 1 is formed in the jacket 2.

In the first tube 1, a second tube 4 is arranged, which protrudes with a piston-like end on the left over the recess 5. The second pipe 4 is designed to be open on this side, so that water can flow from the first pipe 1 into the second pipe 4. On the opposite side, the second tube 4 is closed at its end face. The second pipe 4 is connected in this area in the radial direction to a shower head 3 via a fixing device.

The fixation device comprises a water guide element 10 which is screwed into the second tube 4. The water from the second pipe 4 can flow through the water guide element 10 to the shower head 3.

The fixing device also comprises a fixing element 6 designed as a nut, which is movably mounted on the water-guiding element 10 by means of a threaded connection 8.

In a tightened fixing position, the fixing element 6 presses a clamping element 11 protruding laterally over the recess 5 onto the first pipe 1, so that the second pipe 4 and thus also the shower head 3 are frictionally fixed on the first pipe 1 in the fixing position.

In order to change the position of the shower head 3 in the horizontal direction, the fixing element 6 is brought into a release position by rotation, in which the non-positive fixing via the clamping element 11 on the first pipe 1 is released. The shower head 3 can then be displaced via the fixing device together with the second pipe 4 relative to the first pipe 1 and fixed again in a desired position by tightening the fixing element 6. The fixing device can thus be fixed at any point along the recess 5. When moving, the water guide element 10 functions as a guide element in the recess 5.

The ones in the Figures 3 and 4 The second embodiment shown is basically constructed similarly to the first embodiment of FIG Figures 1 and 2 so that only the essential differences are discussed.

In this second embodiment, the fixing element 6 is sleeve-shaped and can be moved linearly on the water-guiding element 10, a spring 9 being provided which pretensions the fixing element 6 in the direction of the second tube 4.

In addition, the recess 5 has a plurality of latching recesses 7 arranged one behind the other on both sides along its direction of extent.

In the fixing position, the fixing element 6 engages in a pair of opposing locking recesses 7 and thus fixes the second pipe 4 and the shower head 3 in one position in a form-fitting manner.

In order to change the horizontal position of the shower head 3, the fixing element 6 is pulled out of the locking recesses 7 into a release position against the spring force of the spring 9, so that the shower head 3 can be moved together with the second pipe 4 relative to the first pipe 1. In a position predetermined by a pair of opposing locking recesses 7, the fixing element 6 can again come into positive engagement with the locking recesses 7, so that the shower head 3 is fixed in the new position relative to the first pipe 1.

In the second embodiment, the second tube 4 also has rib-like projections on its circumference so that, on the one hand, there is secure guidance in the first tube 1 and, on the other hand, the friction is reduced.
