DETAILED DESCRIPTION OF THE DRAWINGS

[0047] The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

[0048] The shower device illustrated in the figures comprises a pull-out hose device, which comprises a pull-out hose 5 having at least one hose bend 5a of variable hose bend length and a pull-out hose guiding device for guiding the pull-out hose 5. In the exemplary embodiment shown, the pull-out hose 5 comprises two hose bends 5a, 5b, and in alternative embodiments, it comprises only one or three or more hose bends. The pull-out hose guiding device comprises a hose guiding box 1, which is configured for accommodating, in an anti-twist manner in a position hanging inwards with respect to the box, the respective hose bend 5a, 5b. In the view in FIG. 1, a corresponding inward direction B.sub.E with respect to the box points downwards.

[0049] In corresponding embodiments, the hose guiding box 1 comprises, as shown, a box holding frame 2 and a box housing 3 which can be releasably attached to the box holding frame 2, for example by insertion from above into the box holding frame 2. According to requirement, the box housing 3 may then be taken out of the box holding frame 2 again in an upward direction. In alternative embodiments, the hose guiding box is constructed in some other manner, for example with a one-part housing construction without a separate box holding frame.

[0050] The pull-out hose guiding device furthermore comprises a guide weight roller arrangement 6 having at least one guide weight roller 6a which is able to be inserted into a bend reversal region 7a of the hose bend 5a in a manner rotatable about a roller rotational axis D.sub.R. Here, the guide weight roller 6a is, with its roller rotational axis D.sub.R, movable in a translatory manner, outwards with respect to the box with decreasing hose bend length and inwards with respect to the box with increasing hose bend length, in a hose bend longitudinal direction L.sub.S, wherein a corresponding outward direction B.sub.A with respect to the box is opposite to the inward direction B.sub.E with respect to the box and points to outside the hose guiding box 1, upwards in FIG. 1.

[0051] Generally, the guide weight roller arrangement 6 comprises in each case one guide weight roller for each hose bend, and consequently, in the example shown, two guide weight rollers 6a, 6b for the two hose bends 5a, 5b. The guide weight roller arrangement 6 may in particular be one such as described in the aforementioned prior German patent application 10 2017 200 327, to which reference may additionally be made in the present case for further related details. The guide weight roller arrangement 6, together with the dimensioning, matched to the size of the hose bend(s) 5a, 5b, of the hose guiding box 1, assists with anti-twist accommodation of the hose bends 5a, 5b and, owing to the inherent weight of the guide weight rollers 6a, 6b, can additionally assist with returning of the pulled-out pull-out hose 5 into the hose guiding box 1.

[0052] The guide weight rollers 6a, 6b function as loose rollers which, in corresponding embodiments of the pull-out hose device, are, in the installation position, vertically movable in a translatory manner, for which purpose their rotational axis D.sub.R is guided in a vertical guide 20 on the inner side of the box housing 3 in a correspondingly vertically movable manner. In the example shown, the two guide weight rollers 6a, 6b have a common rotational axis D.sub.R, and in alternative embodiments, they are arranged with non-coinciding rotational axes. A sliding bend element 21 which is arranged immovably on the hose guiding box 1, as can be seen for example in FIGS. 4 and 7, serves for the upper hose deflection between the two hose bends 5a, 5b shown.

[0053] Furthermore, the pull-out hose guiding device has a roller blocking device 8 which, in a roller release state, releases the respective guide weight roller 6a, 6b with regard to the translatory movement thereof, and in a roller blocking state, blocks the guide weight roller 6a, 6b against further movement at least beyond a roller blocking position R.sub.B in outward direction B.sub.A with respect to the box. Here, the roller blocking position R.sub.B is spaced apart inwards with respect to the box from an end position E.sub.A outwards with respect to the box of the guide weight roller 6a, 6b. The end position E.sub.A outwards with respect to the box is in this case that position which the guide weight roller 6a, 6b assumes when, as a result of the pull-out hose 5 being pulled out to the maximum extent, the associated hose bend 5a, 5b has its minimum length, that is to say an upper end position in FIG. 1. FIG. 1 shows the pull-out hose device with the pull-out hose 5 completely retracted into the hose guiding box 1, with the result that the hose bends 5a, 5b have their maximum hose bend length and the guide weight rollers 6a, 6b are situated at an end position E.sub.E inwards with respect to the box, that is to say in a lower end position in FIG. 1.

[0054] The shower device, which may for example be a sanitary shower device, further comprises a shower head unit 12, which is coupled to that end of the pull-out hose 5 which is able to be pulled out. In the example shown, the hose guiding box 1 comprises an optional holder 16 for the removable holding of the shower head unit 12. At its other end, the pull-out hose 5 opens into a fluid connection 4 which can be connected with a connection piece 23 to a water supply or some other fluid supply. Here, the fluid connection 4 can be held entirely or partly on the hose guiding box 1, specifically entirely or partly on the box housing 3 and/or on the box holding frame 2. In alternative applications, that end of the pull-out hose 5 which is able to be pulled out may serve as a fluid inlet, and the connecting piece 23 of the fluid connection 4 may serve as a fluid outlet, of the pull-out hose device.

[0055] In corresponding embodiments of the pull-out hose device, the hose guiding box 1 is, as in the example shown, designed so as to be open on a top side 1a and fluid-tight at least in a lower region 1b. In this way, it is possible for fluid, which passes into the hose guiding box 1 owing to a leak or as spray water or for some other reason, to be collected in the box housing 3 with its fluid-tight lower region 1b. The open top side 1a may be used to arrange there that end of the pull-out hose 5 which is able to be pulled out, that is to say to be able there to pull the pull-out hose 5 upwards out of the hose guiding box 1. Optionally, it is possible for the open top side 1a of the hose guiding box 1, specifically of the box housing 3, to be covered by a removable cover rose 9, as in the example shown. In alternative embodiments, the pull-out hose 5 is able to be pulled out on another side of the hose guiding box 1 from the latter, for example at the bottom or at a side. Optionally, the box housing 3 may, as shown, be pro-vided with a reinforcement rib structure 24. This can promote the stability of the box housing 3 and promote production of the housing 3 with a relatively low weight.

[0056] In corresponding embodiments of the pull-out hose device, the respective hose bend 5a, 5b is, as in the example shown, accommodated in the hose guiding box 1 with variable length so as to hang downwards in a U-shaped manner, and the hose guiding box 1 may run in a U-shaped manner on its bottom side and/or have a larger vertical length compared with its horizontal width. This permits a correspondingly large length for the hose bends 5a, 5b in the hose guiding box 1, can limit lateral moving-away of the hose bends 5a, 5b, and makes possible a compact design of the hose guiding box 1. In corresponding embodiments of the pull-out hose device, the hose guiding box 1 has, as in the example shown, a smaller horizontal depth compared with its horizontal width. This promotes anti-twist accommodation of the hose bends 5a, 5b.

[0057] In the exemplary embodiment shown, the shower device is suitable for example as a bathtub hand-held shower device, in the case of which the pull-out hose device may be arranged for example so as to be concealed on the inner side of an associated tub paneling 17, as illustrated in FIGS. 12 and 13. In the example shown, the pull-out hose device is, for this purpose, held on the tub paneling 17 by way of the box holding frame 2 in a corresponding opening of a top side region 17a of the tub paneling 17. This top side region of the tub paneling 17 may for example connect laterally to a tub edge of the bathtub. For use as a hand-held shower device in the bathtub, the shower head unit 12 can be pulled upwards out of the hose guiding box 1. Following use, it can be returned into its holder 16 on the hose guiding box 1 again. The return movement can be assisted by the guide weight roller arrangement 6, in particular by the weight of the guide weight rollers 6a, 6b.

[0058] In corresponding embodiments of the pull-out hose guiding device, the roller blocking position R.sub.B is identical to the end position E.sub.E inwards with respect to the box of the guide weight roller 6a, 6b, as illustrated in FIG. 1. In alternative embodiments, the roller blocking position R.sub.B is situated between the two end positions E.sub.A, E.sub.E of the guide weight roller 6a, 6b and, in this case, preferably closer to the end position E.sub.E inwards with respect to the box than the end position E.sub.B outwards with respect to the box.

[0059] The roller blocking device 8 especially has the advantage that the guide weight rollers 6a, 6b cannot fall arbitrarily far from their hose bends 6a, 6b if the hose guiding box 1 is tilted such that then its lower region 1b is at the top and its open top side 1a is at the bottom, for example while the hose guiding box 1 is being mounted or dismounted or for the purpose of emptying collected leak fluid. Without the roller blocking device, the guide weight rollers 6a, 6b could in this case fall downwards from the respective bend reversal region 7a, 7b of the hose bends 5a, 5b to their end position E.sub.A outwards with respect to the box, in case the latter is defined in a stop-limited manner, or even fall completely out of the hose guiding box 1, if this is not prevented by another measure. The roller blocking device 8 ensures that the guide weight rollers 6a, 6b cannot move away beyond the roller blocking position R.sub.B in the outward direction B.sub.A with respect to the box in such a case.

[0060] In a corresponding embodiment, as is shown in FIGS. 1 to 6, the roller blocking device 8 has a blocking bracket 10 which, on the one hand, is coupled fixedly in terms of translation to the roller rotational axis D.sub.R and, on the other hand, has a bracket section 10a for engaging behind the respective hose bend 5a, 5b on its lower side in its bend reversal region 7a, 7b. In corresponding embodiments with a plurality of guide weight rollers 6a, 6b for a corresponding plurality of hose bends 5a, 5b, as in the example shown, the blocking bracket 10 is, with its bracket section 10a, configured for engaging behind a plurality of the hose bends 5a, 5b on their lower side in their respective bend reversal region 7a, 7b. This may be all, or in any case a portion of, the plurality of hose bends 5a, 5b which are present overall.

[0061] In corresponding embodiments, for at least two of the guide weight rollers 6a, 6b, a common rotary bearing unit 11 is, as in the exemplary embodiment shown, provided, and the blocking bracket 10 has a central web section 10b which is coupled by way of an end region 13a to the rotary bearing unit 11 and which extends between two of these at least two guide weight rollers 6a, 6b. In this case, the blocking bracket 10 also has two bracket sub-sections 14a, 14b which project in a manner opposite one another on the other end region 13b of the central web section 10b.

[0062] Optionally, as in the example shown, there is provided on the bracket section 10a or on the bracket sub-sections 14a, 14b a guide extension 15a, 15b which not only forms, together with the bracket section 10a and the central web section 10b of the blocking bracket 10, a U-shaped guide aid for the associated hose bend 5a, 5b guided through therein, but also can serve as an anti-twist means for the blocking bracket 10. For this purpose, the guide extension 15a, 15b engages into the vertical guide 20, which is formed for example as a vertical groove on the inner wall of the box housing 3 and in which the guide weight rollers 6a, 6b are also guided with regard to the translatory movement thereof, for example in that the rotary bearing unit 11 engages with its ends on both sides into in each case one of the vertical guides 20 formed on opposite side walls of the box housing 3.

[0063] The rotary bearing unit 11 functions as a common bearing for the guide weight rollers 6a, 6b and defines their common rotational axis D.sub.R. Preferably, the guide weight rollers 6a, 6b are arranged parallel and offset from one another in the direction of the rotational axis D.sub.R. In the example shown, the guide weight rollers 6a, 6b are also arranged parallel to side walls of the hose guiding box 1, as can be seen in particular from FIGS. 5 and 6, and in alternative embodiments, they are arranged inclined with respect to the box side walls. In the exemplary embodiment shown, the blocking bracket 10 and the rotary bearing unit 11 are formed by a corresponding combination component, as can be seen from FIG. 2, and alternatively, the holding bracket 10 may be connected fixedly in terms of translation to the rotary bearing unit 11 in some other manner.

[0064] In this realization of the blocking bracket, the roller blocking device 8 has the property that it firmly holds the guide weight rollers 6a, 6b, or blocks the latter against further movement in the outward direction B.sub.A with respect to the box, in their respective present position in the bend reversal region 7a, 7b of the associated hose bends 5a, 5b if the roller blocking de-vice 8 reaches its roller blocking state. In this example, this is the case if, proceeding from its vertical position of use, the hose guiding box 1 is tilted by more than 90, so that, without the roller blocking device 8, the guide weight rollers 6a, 6b could fall downwards from the hose bends 5a, 5b. The blocking bracket 10 prevents this in any vertical position of the guide weight rollers 6a, 6b, that is to say for any present hose bend length of the hose bends 5a, 5b, in that, in this tilted position of the hose guiding box 1, the bracket 10 comes to bear, with its bracket section 10a, on the respective hose bend 5a, 5b in the region of the reversal point thereof. In this way, the hose bends 5a, 5b, with their bend deflection regions 7a, 7b, hold the guide weight rollers 6a, 6b firmly in their vertical position in the bend de-flection regions 7a, 7b. For this purpose, the hose bends 5a, 5b possess the required inherent stiffness and/or are supported laterally against the adjacent narrow side walls of the hose guiding box 1.

[0065] Thus, in this realization of the blocking bracket of the roller blocking device 8, the guide weight rollers 6a, 6b are held firmly in the end position E.sub.E inwards with respect to the box if they are present there at the time of the tilting of the hose guiding box 1, that is to say the roller blocking position R.sub.B is then identical to the end position E.sub.E inwards with respect to the box. If the hose guiding box 1 is tilted with a partly or fully pulled-out pull-out hose 5, the guide weight rollers 6a, 6b are blocked against further movement in the outward direction B.sub.A with respect to the box in the correspondingly raised present position of the rollers 6a, 6b, which position then forms the roller blocking position R.sub.B.

[0066] FIGS. 7 to 11 illustrate alternative embodiments of the roller blocking device 8. In the realization shown in FIGS. 7 and 8, the roller blocking device comprises a pivotable pivot lever 18 which extends from an actuation end 18a outwards with respect to the box on an operating side of the hose guiding box 1 to a blocking section 18b inwards with respect to the box, and is pivotable between a blocking element release position B.sub.F, which is shown in FIG. 7, and a blocking element blocking position B.sub.B, which is shown in FIG. 8. In the example shown, the open top side 1a of the hose guiding box 1 acts as the operating side, and the pivot lever 18 is able to be pivoted about a pivoting axis situated in the vicinity of the lowermost point of the hose guiding box 1.

[0067] With its blocking section 18b, the pivot lever 18 engages into a roller rotational axis guiding path F.sub.W in a blocking manner in the blocking element blocking position B.sub.B, which path is given by the vertical guide 20 in the example shown and generally refers to the guided translation path along which the respective guide weight roller 6a, 6b is, with its roller rotational axis D.sub.R, moved in a translatory manner if the length of the associated hose bend 5a, 5b is changed by the pulling-out or pulling-in of the pull-out hose 5. In the example shown, the pivot lever 18 has, for this purpose, a blocking lug 19 in its blocking section 18b, which lug, in the blocking position B.sub.B of the pivot lever 18, is situated in the guide path F.sub.W of the roller rotational axis D.sub.R or of the rotary bearing unit 11. In this way, the blocking lug 19 blocks the guide path F.sub.W for the guide weight rollers 6a, 6b, which consequently are not able to move beyond the blocking lug 19 in the outward direction B.sub.A with respect to the box from a position which is inwards with respect to the box in relation to the blocking lug 19. Consequently, in this example, the roller blocking position R.sub.B for the guide weight rollers 6a, 6b is determined by the position of the blocking lug 19. In the blocking element release position B.sub.F, the blocking lug 19 is pivoted out of the roller rotational axis guide path F.sub.W such that the guide weight rollers 6a, 6b are able to move freely along the roller rotational axis guide path F.sub.W or the vertical guide 20.

[0068] FIGS. 7 and 8 show an embodiment in which the blocking lug 19 is provided at one location of the pivot lever 18, which results in the roller blocking position R.sub.B being identical to the end position E.sub.E inwards with respect to the box or, in any case, being spaced apart by a small clearance therefrom. In alternative embodiments, the blocking lug is provided at a location on the pivot lever 18 which is situated further in the outward direction B.sub.A with respect to the box. In this case, the guide weight rollers 6a, 6b are then able to move to a corresponding extent out of their end position E.sub.E inwards with respect to the box as far as the roller blocking position R.sub.B between the two end positions E.sub.E and E.sub.A. In any case, it is in these realizations also prevented that the guide weight rollers 6a, 6b can fall out as far as the end position E.sub.A outwards with respect to the box or completely out of the hose guiding box 1.

[0069] At the actuation end 18a outwards with respect to box, a user can actuate the pivot lever 18, that is to say pivot the lever 18 between its blocking position B.sub.B and its release position B.sub.F, at the accessible box top side 1a. If as shown the hose guiding box 1 is constructed from the box holding frame 2 and the box housing 3 which is able to be inserted therein, the pivot lever 18 may optionally have a releasable, that is to say unlockable, dismounting locking element for the hose guiding box 1. If the pivot lever 18 is in its blocking element release position B.sub.F, the locking element locks the box housing 3 in the box holding frame 2, that is to say the box housing 3 cannot be removed from the box holding frame 2. If the pivot lever 18 is in its blocking element blocking position B.sub.B, the dismounting locking element is in an unlocking position in which the dismounting of the box housing 3 from the box holding frame 2 is released by it. In this way, it can be ensured that the roller blocking device 8 is in its roller blocking state if the box housing 3 is removed from the box holding frame 2.

[0070] The dismounting locking element may be realized for example by a corresponding locking bracket, which is formed in the region of the actuation end 18a on the pivot lever 18. The locking bracket can act directly on the box holding frame 2 and the box housing 3, or alternatively for example on a holding bracket arrangement having at least one holding bracket which is arranged so as to be able to perform a folding movement at the box top side 1a on the box housing 3. For its part, the holding bracket may have dismounting prevention means such that it blocks the removal of the box housing 3 from the box holding frame 2 if it is in a position folded down parallel to the box top side 1a, and releases the dismounting of the box housing 3 from the box holding frame 2 if it is in a folded-up state in which it can function as a handling means for the removal of the box housing 3 from the box holding frame 2. In this case, the locking bracket of the pivot lever 18 blocks the folding-up of the holding bracket(s) if the pivot lever 18 is in its blocking element release position B.sub.F. As soon as the pivot lever 18 is pivoted into its blocking position B.sub.B, its locking bracket releases the folding-up of the holding bracket(s).

[0071] In the embodiment shown in FIG. 9, the roller blocking device 8 comprises a rotatable threaded control rod 19 and a blocking element which is movable by the rod 19 between a blocking element release position B.sub.F and a blocking element blocking position B.sub.B, wherein here too, the blocking element release position B.sub.F is that position in which, in this case by way of the blocking element, the roller blocking device 8 is in the roller release state and the blocking element blocking position B.sub.B is that position in which the roller blocking device 8 is in the roller blocking state. In this example, the blocking element is in the form of a blocking bolt 22 which engages into the roller rotational axis guiding path F.sub.W of the guide weight rollers 6a, 6b in a blocking manner in the blocking element blocking position B.sub.B. The threaded control rod 19 extends from an actuation end 19a outwards with respect to the box on an operating side, here again the box top side 1a, to a threaded section 19b inwards with respect to the box, with which the blocking element 22 cooperates.

[0072] If the user rotates the threaded control rod 19 at its actuation end 19a, the blocking bolt 22 is moved into the roller axis guiding path F.sub.W, or out of the guiding path F.sub.W, transversely with respect to the longitudinal direction of the threaded control rod 19. In this way, the blocking element 22 acts in the same manner as the blocking lug 19 of the pivot lever 18 in the embodiment in FIGS. 7 and 8. Moreover, like the blocking lug 19, the blocking element 22 may, as an alternative to its position shown in FIG. 9, in which it holds the guide weight rollers 6a, 6b firmly in the region of their end position E.sub.E inwards with respect to the box, be arranged at some other location along the threaded control rod 19 or along the roller rotational axis guide path F.sub.W.

[0073] In a realization illustrated in FIG. 10, the roller blocking device 8 comprises, similarly to the example in FIG. 9, a rotatable threaded control rod 25, which extends from an actuation end 25a outwards with respect to the box on an operating side of the hose guiding box 1 to a threaded section 25b inwards with respect to the box, and a blocking element, which cooperates with the threaded section 25b inwards with respect to the box of the threaded control rod 25 and is movable thereby between a blocking element release position B.sub.F and a blocking element blocking position B.sub.B. In this exemplary embodiment, the blocking element is formed by a blocking log 26 which comes to bear against a roller surface of the guide weight rollers 6a, 6b in a blocking manner in the blocking element blocking position B.sub.B. Thus, in this case, the roller blocking device 8 blocks the guide weight rollers 6a, 6b with respect to moving-away along the roller rotational axis guiding path F.sub.W not in that it blocks the guiding path F.sub.W, but in that the blocking log 26 is pressed against the roller surface of the guide weight roller 6a, 6b and, in this way, firmly holds the guide weight rollers 6a, 6b themselves owing to corresponding mechanical clamping. For example, it is possible in corresponding embodiments for the blocking log 16 to come to bear laterally against the axial outer side of the adjacent guide weight roller 6a, 6b. In this embodiment too, the position of the blocking log 26 along the inward direction B.sub.E with respect to the box or the outward direction B.sub.A with respect to the box may be selected in a variable manner. In the position shown, the blocking log 26 again secures the guide weight rollers 6a, 6b in the region of their end position E.sub.E inwards with respect to the box. Upon rotation of the threaded control rod 25 at its actuation end 25a by the user, the blocking log 26 again moves transversely with respect to the longitudinal direction of the threaded control rod 25, in this case however in a plane parallel to the roller rotational axis D.sub.R. This may be realized for example in that the blocking log 26 is constructed from two log halves, or log plates, which are movable with respect to one another via an inclined surface coupling.

[0074] In a realization shown in FIG. 11, the roller blocking device comprises an axially movable control rod 27 and a blocking element which is movable by the rod 27 between a blocking element release position B.sub.F and a blocking element blocking position B.sub.B. In the exemplary embodiment shown, the blocking element is formed by a spring tongue element 28 which is held in the hose guiding box 1 or the box housing 3 in a manner preloaded in its blocking position. The control rod 27 extends from an actuation end outwards with respect to the box 27a on an operating side of the hose guiding box 1 to a control section inwards with respect to the box 27b, with which the spring tongue element 28 cooperates, wherein it engages into the roller rotational axis guiding path F.sub.W of the guide weight rollers 6a, 6b in a blocking manner in the blocking element blocking position B.sub.B shown.

[0075] Axial actuation of the control rod 27 allows the user to move the spring tongue element 28 between its release position and its blocking position. If the control rod 27 is pushed forwards axially, that is to say downwards in FIG. 11, by the user, the control rod 27 presses, with its control section inwards with respect to the box 27b, the spring tongue element 29 counter to the spring force thereof (obliquely downwards in FIG. 11) from the roller rotational axis guiding path F.sub.W into its blocking element release position B.sub.F. Correspondingly, the guiding path F.sub.W is then released for the guide weight rollers 6a, 6b or the roller rotational axes D.sub.R thereof, and the guide weight rollers 6a, 6b are again unblocked. In this embodiment too, the spring tongue element 28 may, as desired, be arranged at any location along the roller rotational axis guiding path F.sub.W where the blocking for the guide weight rollers 6a, 6b is to be brought about.

[0076] As is made clear by the exemplary embodiments which are shown and which are explained further above, the invention very advantageously provides a pull-out hose guiding device by way of which the hose bends of a pull-out hose can be guided in a hose guiding box using a guide weight roller arrangement, and the guide weight roller arrangement can be transferred into a blocking position which prevents one or more guide weight rollers from falling out of the hose guiding box or the rollers from performing undesirably large translatory movement within the hose guiding box. The pull-out hose guiding device can be used anywhere where there is a requirement for being able to guide in a controlled manner a pull-out hose having one or more hose bends, in particular for sanitary shower devices, but also for non-sanitary shower devices and further sanitary and non-sanitary applications.

[0077] Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
