Description

The present invention relates to a shower device comprising at least a first water-carrying pipe which has a jacket and a shower head which is fluidly connected to the first pipe.

Shower devices are known from the prior art, in which a tube not only serves to hold the shower head and an optionally additional hand shower, but also serves to direct the water to the shower head attached to the tube. For this purpose, the pipe generally 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 tube, via which the water can also be directed to a hand shower, which can be detachably attached to a separate holding device that can be slid along the vertical section of the tube. The known shower devices have the disadvantage that the height of the shower head and also its distance from the wall are determined by the dimensions of the pipe.

Out of DE 26 01 059 B1 a shower device is known in which the shower head can be displaced along a guide rail. Out of U.S. 2015/048181 A1 Another shower device is known, in which the shower head can be displaced along a guide rail, without describing how the shower head can be fixed in one position.

The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to specify 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 solved by a shower device with the features of the independent claim. Advantageous developments of the shower device are specified in the dependent claims and in the description, with individual features of the advantageous developments being able to be combined with one another in a technically meaningful manner.

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

In its basic idea, the invention therefore provides that the relative position of the second tube in the first tube can be easily changed by releasing the fixing device and moving the second tube in the released state (release position) in the first tube, thereby easy way to change the position of the shower head. Since the fixing device is connected to the second tube, a user transfer the fixing element from the fixing position to the release position with one hand and move the second tube in the release position by means of the fixing 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 inadvertently come out of the first tube.

The cross section of the first tube can have any configuration, such as round, oval, elliptical, or angular. The cross-sectional shape of the first tube is generally constant along its length. At least on a section arranged in the first pipe, the second pipe has an outer cross-sectional configuration that corresponds to the inner cross-sectional configuration of the first pipe, wherein at least one O-ring can be arranged as a seal between the outer circumference of the second pipe and the inner circumference of the first pipe.

In its section arranged in the first pipe, the second pipe can have regions with a smaller outside diameter in sections in order to reduce the friction with the first pipe. 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 enable secure 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 and into the first tube. The second tube is preferably arranged with a piston-shaped section in a sealing manner in the water-carrying part of the first tube.

The second tube has an opening, in particular on one end face, through which the water passes from the first tube into the second tube. The second tube is usually closed on the opposite side, with a fluid connection being realized from the second tube to the shower head in the radial direction of the second tube through the jacket of the second tube. 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 the recess provides a guide for the fixing device on the one hand and forms a stop for the fixing device on the other hand at its axial ends.

The fixing device has in particular a guide element which is connected through the recess in the casing of the first tube to the section of the second tube arranged in the first tube, in particular detachably, 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 assembling the shower device, the second pipe is inserted into the first pipe from an end opposite the water inlet of the first pipe, with 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 tube is fixed in the first tube via a non-positive and/or positive connection when the fixing element is in its fixing position.

To produce a non-positive connection, the fixing element can preferably be designed as a screw element (for example as a nut), the screw element being screwable in particular on the guide element which protrudes through the recess and has 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 peripheral surface of the first tube, which 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 arranged in particular transversely to its direction of extent and one behind the other in the direction of extent, the fixing element engaging in at least one of the latching recesses in a form-fitting manner in the fixing position. Snap-in recesses which are preferably arcuate and lie opposite one another are preferably formed on both sides of the recess along the direction in which they extend. In the fixing position, the fixing element is therefore located within a locking recess or a pair of locking recesses, whereas in the release position the fixing element is out of the Locking recess is moved out. Thus, however, positions defined by the locking recesses are specified, in which the fixing element can be brought into the fixing position.

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 rotary movement by means of a threaded connection. Here, 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 prestressed 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 move it in this state along the recess together with the second tube, the fixing element automatically returning to the fixing position due to the spring.

The recess thus 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 aligned section of the first tube. Accordingly, the section of the second tube arranged in the first tube is also aligned vertically. In this embodiment, the second tube projects beyond the first tube, with 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 tube into the first tube to different extents using 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 aligned section of the first tube, so that the section of the second tube arranged in the first tube is also horizontally aligned. 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 completely arranged 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 this embodiment in particular, 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 in particular the component of the fixing device referred to above as the guide element forms a water guiding element, which is connected on the one hand to the second pipe and on the other hand to is connected to the shower head and thus leads the water from the second pipe to the shower head, the fixing element being on the outside of the water guiding element is movably mounted. The tubular water guiding element is thus screwed into the second tube, the fixing element explained in more detail above being movably arranged on the outside of the water guiding 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 extension direction of the first tube 1 is formed in the jacket 2 .

A second tube 4 is arranged in the first tube 1 and protrudes with a piston-like end over the recess 5 on the left-hand side. The second pipe 4 is 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. In this area, the second pipe 4 is connected to a shower head 3 in the radial direction via a fixing device.

The fixing device includes a water guiding element 10 which is screwed into the second pipe 4 . The water from the second pipe 4 can flow through the water guiding element 10 to the shower head 3 .

The fixing device also includes 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 beyond the recess 5 onto the first tube 1, so that the second tube 4 and thus also the shower head 3 are non-positively fixed to the first tube 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 rotating it, 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 moved relative to the first tube 1 together with the second tube 4 via the fixing device 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 acts as a guide element in the recess 5.

The in the Figures 3 and 4 The second embodiment shown is basically constructed similarly to the first embodiment 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 prestresses 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 the direction in which it extends.

In the fixing position, the fixing element 6 engages in a pair of opposing latching recesses 7 and thus fixes the second tube 4 and the shower head 3 in a position with a positive fit.

In order to change the horizontal position of the shower head 3, the fixing element 6 is pulled out of the latching recesses 7 into a release position against the spring force of the spring 9, so that the shower head 3 together with the second tube 4 can be displaced relative to the first tube 1. In a position specified by a pair of opposite 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 tube 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 reliable guidance in the first tube 1 and on the other hand the friction is reduced.
