Description

The invention relates to a mounting arrangement for a shower hose, in particular a shower hose in a wash basin or the like.

It is known that, in particular in horizontally extending washstands, the hand shower is supplied via a hose with water, which is guided through a passage in the wash basin. When not in use, the hand shower sits in the duct itself, and the hose hangs down below the vanity. Often there is a device to pull the tubing back through the duct ( DE 3901007 ).

It has been found that the automatic retraction of the shower hose can be distracting under certain circumstances, especially if you only briefly put the shower out of hand to do something different. In contrast, the withdrawal of the hose is very useful in itself.

Furthermore, a hose shower mixer ( DE 2850647 A1 ), where the hose is automatically wound up. There is provided a brake which prevents the withdrawal of the hose and which can be unlocked by pressing a button or the like.

In another hose feedthrough, a hose is passed between two rollers having a reduced diameter portion. The hose can be pulled through in both directions. To fix it in a certain position, the hose must be moved transversely to its longitudinal direction between sections of the two rollers which have an enlarged diameter ( BE 424812 ).

Even with cable drums for electrical lines, it is known to fix the cable in a certain position. A slidably mounted roller jammed the cable. In order to release the clamping, the cable has to be moved laterally to prevent the displaceably mounted roller from returning to its clamping position ( EP 791553 ).

The invention is based on the object to provide a way to further improve the benefits of use of such a hand shower.

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

In horizontally extending washstands, in which the implementation thus runs vertically, the hose is often withdrawn under its own weight. The provision of a retaining device now makes it possible to prevent automatic retraction. The holding device provided for this purpose is of course useful not only for horizontally extending washstands with vertically extending passage, but also in all types of hose assemblies in which a retraction of the hose for reasons of practicality is desired. The invention combines the advantage of automatically retracting the hose with the ability to turn off this automatic under certain circumstances.

According to the invention may be provided in a further development that the retaining means is arranged on or in the lead-through element. There are therefore no visible at least on the outside additional facilities that would complicate the structure or increase the cost.

Of course, the retainer serves, of course, to prevent retraction of the hose. But it is also conceivable to construct a retaining device so that it prevents the movement of the hose in both directions.

In a further development, it is provided that the clutch for releasing or actuating the retaining device can be actuated by handling the hose itself.

Another possibility also proposed by the invention is to design the coupling so that it is released by pulling on the hose and actuated again by pulling again on the hose.

The retaining device can achieve the fixing of the tube in the at least one direction in a variety of ways. Since a shower hose usually consists of a rubber-like material, one can use to his determination a traction that deforms the shower hose something. A relatively simple embodiment can achieve this.

Another way to hold the shower hose, is that this is held at least partially positive fit. This lends itself to the usually coiled or ribbed shower hoses.

Since the retaining device with the help of the coupling should be able to release the hose again, it may for example be designed such that it holds the hose only in a certain rotational position of the hose relative to the retaining device, while it passes in another rotational position. Here, the decoupling would therefore consist in turning the shower hose or a connected to the shower hose part by a certain angle.

To achieve such a configuration, it is provided that the retaining device has a sleeve which has at least one position an inwardly projecting inclined surface. This inclined surface can be considered as a wedge surface or as a cam against which another part can accumulate, thereby holding the hose.

In the remaining peripheral region, the sleeve may have a design in which the inner diameter is not reduced, that is, for example, remains cylindrical.

The retaining device has, in a further development, a clamping sleeve, which is guided in the outer sleeve movable limited and at least one circumferential position has a over the rest of the clamping sleeve projecting outward projection.

This projection can cooperate with the inclined surface of the outer sleeve for the preparation of the deadlock.

The outer sleeve of the fixing device may in particular form a part of the lead-through element.

The projection of the clamping sleeve may extend, for example, only over part of the circumference of the clamping sleeve, while over the remainder of the circumference then no projection is present. There may also be a plurality of such projections.

Advantageously, the circumferential extent of the projections or even a single projection can be chosen so that it is smaller than the gap between the inclined surfaces of the outer sleeve measured in the circumferential direction. Then, the clamping sleeve can be rotated in a position in which there is no engagement between the projections and inclined surfaces, which corresponds to a release position. In another rotational position, the intervention then occurs.

In a further development of the invention, the projection is movably arranged in the radial direction, for example formed on a resilient part. During its radial inward movement, a part connected to it, or even its radially inner side, can then come into frictional connection and / or positive engagement with the hose guided through the clamping sleeve. The interaction between the projection and the inclined surface thus simultaneously leads to the determination of the clamping sleeve on the hose.

For example, the projection may be formed on an integrally formed tongue of the clamping sleeve. This tongue can additionally serve to produce a slight frictional connection between the hose and the clamping sleeve in the longitudinal direction of the hose.

It is also possible and within the scope of the invention that the at least one projection is formed on a separate component, which is then attached to the clamping sleeve. This separate component can also be designed in such a way that the rear side of the projection simultaneously forms the part which comes into frictional connection and / or positive connection with the shower hose.

The clamping sleeve, which forms part of the retaining device, is designed so that it is entrained when moving the hose with this at least in the longitudinal direction of the hose. This allows the clutch to be operated by moving the hose.

In a further development of the invention may be present between the outer sleeve and the clamping sleeve a sliding guide, which aligns the at least one projection of the clamping sleeve alternately either with the inclined surface of the outer sleeve or with the space between the inclined surfaces.

This link guide, for example, have a link on the outer sleeve and at least one cooperating with the link pin on the clamping sleeve. In particular, the slotted guide can be designed such that it extends over a full circumference, thus enabling complete rotation of the clamping sleeve. The clamping sleeve is thus brought to the first pulling of the hose to the outside in a position from which it is brought when retracting the hose in the locked position. When re-pulling the hose, the clamping sleeve is then rotated again so that it then reaches the release position.

It would also be conceivable that the clamping sleeve is constantly rotated back and forth due to the slotted guide.

Since only a small adhesion is present between the clamping sleeve and the shower hose, the constant rotation in one direction still does not lead to a twisting of the hose, as it can always reset itself.

FIG. 1 shows a section through a support assembly according to the invention. The mounting arrangement includes a feedthrough element 1, which is designed for insertion into an opening of a horizontally extending plate. The lead-through element 1 contains a part 2 to be arranged above the surface of the plate with an obliquely extending holder 3 into which the cone part 4, for example a hand shower, can be inserted. This cone part 4 is held in the holder 3. The cone part 4 is formed by a union nut which is attached to the end of a shower hose 5. The shower hose 5 passes through the feedthrough element 1 therethrough. It contains below its visible part 2 a nozzle 6, which ends in a support shoulder 7.

In the lead-through part or its neck 6, an extension part 8 is inserted from below, which is snapped with a peripheral edge 9 in the inside of the nozzle 6. The extension part 8 ends in a projection with an external thread 10, see FIG. 2 , In this external thread 10, a coupling sleeve 11 of a protective tube 12 is screwed. The protective tube 12 surrounds the shower hose 5. The protective tube 12 includes in its interior a helical compression spring, which is supported at the upper end of the coupling sleeve 11, while it is supported at the lower end to a connecting part of the shower hose 5 with a connection. The helical compression spring 13, which is only indicated, tries to straighten the shower hose 5 and pulls it down so that the cone bottom 4 is pulled into the holder 3.

Within the extension part 8, an outer sleeve 14 of a retaining device is used, which is composed of an upper part 14 a and a lower part 14 b. The upper part 14 a contains in his upper area a curved inner wall 15, against which the shower hose. In the region of the lower end of the lower part 14 b of the outer sleeve includes a plurality of inwardly directed projections 16, of which in FIG. 2 two can be seen. Between the upper and lower part 14 a, 14 b of the outer sleeve 14, a slide guide 17 is arranged, which has a plurality of teeth and between the teeth depressions. A settlement of the slide guide 17 is in FIG. 3 shown.

The shape of the backdrop is now referring to FIG. 3 explained. The lower scenery begins, starting on the right, with an oblique curve 18, followed by a U with parallel legs. The following leg 19 again runs parallel to the longitudinal direction and ends in a point 20, from which the curve is repeated.

The opposite backdrop is similar, but the oblique portion passes over an arcuate shape in the direction parallel to the longitudinal section.

The tips 20 of each backdrop are approximately midway between the tips 20 of the other backdrop. The two scenes are so to speak arranged on a gap.

An indicated pin 21, which lies in the lower backdrop, when pushing up to the oblique curve and then slips further into the lowest point of the other backdrop, from where he is then pushed back into the next recess of the scenery. When you put on and push off an indicated pin 21 so this is pushed in each case by a depression. So this represents a progression mechanism.

The FIGS. 4 to 6 now show the interaction of the tube 5, a clamping sleeve 22 and the outer sleeve 14 in various stages. On the outside of the tube 5, a clamping sleeve 22 is arranged, which is fixed to the hose 5 frictionally. This is best seen in FIG. 7 , If now the hose is pulled out of the lead-through element, then the clamping sleeve 22 is pushed upward until it comes to a shoulder 23 of the outer sleeve to the plant. This limits their further movement. The tube 5 can be further pulled out of the feedthrough element. Since the force with which the clamping sleeve fixes on the tube 5 is only slight, the further withdrawal of the tube 5 is hardly hampered.

Now, if the hose pulled by the aforementioned spring 13 back into the lead-through element, for example, because the user lets go of the hand shower, there are basically two ways in which the further procedure is. Depending on the starting position of the pin 21 in the backdrop can now in FIG. 5 shown position occur in which the clamping sleeve 22 is pushed down. In this position, the hose can be pulled through completely and without obstruction by the feedthrough element.

In another position, in which the clamping sleeve 22 is twisted slightly about the longitudinal axis of the tube, enters the FIG. 6 condition shown. Here are parts of the clamping sleeve 23 on the mentioned projections 16 on the inside of the outer sleeve 14, so that these parts are now pressed onto the hose and set this. This thus represents the blocking position of the retaining device, in which the hose can not be pulled further through the lead-through element.

It has already been on the FIG. 7 refer where it is shown how the clamping sleeve 22 is disposed on the outside of the tube 5. The clamping sleeve has, approximately in the middle between the two pins 21, cuts with resilient tongues 24. These resilient tongues 24 are integrally formed on the upper end of the hand shower associated with the clamping sleeve 22 in the region of its lower end but free. They are slightly above the outer contour of the clamping sleeve 22 in the region of their lower end. Due to the material properties, these tongues 24 are somewhat springy, so that in comparison between the FIGS. 4 and 6 to see deformations are easily possible.

Within the feedthrough element, the outer sleeve is arranged, which in the representation of FIG. 8 is placed on the clamping sleeve 22. Here it can be seen that the pins 21 engage in the backdrop on the slotted guide. An axial movement of the tube 5 thus results in that the clamping sleeve is also rotated in each case during its axial displacement.

The projections 25 formed at the ends of the tongues 24 have a circumferential extent approximately equal to the distance between two inwardly directed inclined surfaces 16 of the outer sleeve 14. As a result, depending on the orientation, the projection 25 with the spaces between the inclined surfaces 16 are aligned, see FIG. 5 , so that the hose can be pushed through the clamping sleeve.

In a twist then get the projections 25 of the tongues 24 in an angular position where they are aligned with the inclined surfaces 16. This represents the FIG. 6 Here are the projections 25 on the inclined surfaces 16 at. The stronger the hose is pulled down, the stronger is the radial loading of the hose inwards and thus its fixing.

The retaining device thus operates as follows. First, the hose is pulled out, which is possible from all positions ago. When pulling back the hose, caused by the spring 13, for example, the position of the FIG. 6 achieved, which represents a holding the hose. To release the hose then again, the user only needs to pull on the hose for a short time until the clamping sleeve with its pins 21 is rotated so far through the slotted guide, that when releasing the position of the FIG. 5 is taken. Then the tube 5 can be pulled unhindered through the clamping sleeve and thus through the implementation.

While in the embodiment of the FIGS. 4 to 8 the projections 25 are arranged at the ends of integral tongues 24, the following figures show a clamping sleeve, which is constructed somewhat differently.

Similar to the previous embodiment, the clamping sleeve 32 consists of two parts, which are identically constructed and can be snapped together. The clamping sleeve 32 has on its outer side two diametrically arranged pins 21 which have the same function as in the previous embodiment. In the incisions again tongue-like formations 34 are arranged, which are connected in one piece with the clamping sleeve 32 on both end faces. These slightly inwardly preformed tongues 34 are used exclusively for fixing the clamping sleeve 32 to the hose. This definition is necessary so that the indexing of the clamping sleeve through the slotted guide is even possible.

The clamping sleeve 32 has in its lower end, that is to say the installation end of the hose, an encircling groove 35 into which a clip 36 is snapped. The clasp 36 extends over about half the circumference. It is defined by the groove 35 in the axial direction. It has in the region of its two ends depending on a projection 37, see FIG. 11 , wherein the projection 37 is dimensioned so that it projects beyond the other circumference of the clamping sleeve in the lower region. The two projections 37 take over the task of the projections 25 in the embodiment according to FIGS. 4 to 7 , On the opposite sides of the projections of the clips 36 two axially offset ribs 38 are formed, wherein the axial offset of these two ribs 38 corresponds approximately to half the pitch of the spiraling of a conventional shower hose. You can do that FIGS. 4 to 7 see that the shower hose has a kind of thread. When moving the projections 37 inwardly, the ribs 38 pass between two turns of the shower hose 5, so that they achieve in this way a positive fixing of the shower hose relative to the clamping sleeve 32.

The FIG. 13 that are similar to the FIGS. 11 and 12 shows a cross section through the clamping sleeve 32, represents how the two parts of the clamping sleeve be attached to each other. Each half of a clamping sleeve has a resilient projection 38 which engages with a nose behind an undercut of the respective other half of the clamping sleeve.

FIG. 14 shows again in perspective a clamping sleeve 32 of the embodiment according to the FIGS. 9 to 13 ,
