Abstract

A pull-out hose guiding device for guiding a pull-out hose having at least one hose bend of variable hose bend length, wherein the pull-out hose guiding device includes a hose guiding box configured for accommodating the hose bend in an anti-twist manner in a box-inwards hanging position, and a guide weight roller arrangement including at least one guide weight roller which is insertable into a bend reversion zone of the hose bend for rotary motion about a roller rotational axis. The guide weight roller with its roller rotational axis is capable of translational motion in a hose bend lengthwise direction box-outwards with decreasing hose bend length and box-inwards with increasing hose bend length. A sanitary shower device may be equipped with such a pull-out hose guiding device.

First claim

The invention claimed is:

1. A pull-out hose guiding device for guiding a pull-out hose having at least one hose bend of variable hose bend length, comprising:
a hose guiding box configured for accommodating the hose bend in an anti-twist manner in a box-inwards hanging position;
a guide weight roller arrangement including at least one guide weight roller which is insertable into a bend reversal region of the hose bend for rotary motion about a roller rotational axis, wherein the guide weight roller with its roller rotational axis is capable of translational motion in a hose bend lengthwise direction box-outwards with decreasing hose bend length and box-inwards with increasing hose bend length; and
a roller blocking device which releases the guide weight roller in its translational motion in a roller release condition and blocks the guide weight roller against further movement at least in a box-outwards direction beyond a roller blocking position in a roller blocking condition, wherein the roller blocking position is spaced box-inwards from a box-outwards end position of the guide weight roller, the box-outwards end position corresponding to a minimum hose bend length,
wherein the roller blocking device comprises a blocking bracket coupled with the roller rotational axis for conjoint translational motion and having a bracket section for engaging behind the hose bend in its bend reversal region on a lower side of the hose bend so as to extend with its bracket section below a bottom side of the bend reversal region.

2. The pull-out hose guiding device according to claim 1 , wherein the roller blocking position is a box-inwards end position of the guide weight roller or has a distance from the box-inwards end position that is at most as great as half the distance of the box-inwards end position from the box-outwards end position of the guide weight roller.

3. The pull-out hose guiding device according to claim 1 , wherein a plurality of guide weight rollers for a corresponding plurality of hose bends of the pull-out hose is provided and the blocking bracket and its bracket section are configured for engaging behind a plurality of the hose bends in their bend reversal regions on a lower side thereof.

4. The pull-out hose guiding device according to claim 3 , wherein for at least two of the guide weight rollers a common rotation bearing unit is provided and the blocking bracket comprises a central web section coupled to the common rotation bearing unit with an end region, which central web section extends between two of the at least two guide weight rollers, and comprises, as the bracket section, two bracket subsections protruding in opposite directions on another end region of the central web section.

5. The pull-out hose guiding device according to claim 1 , wherein the pull-out hose guiding device is configured to guide a pull-out hose of a sanitary shower.

6. A pull-out hose guiding device for guiding a pull-out hose having at least one hose bend of variable hose bend length, comprising:
a hose guiding box configured for accommodating the hose bend in an anti-twist manner in a box-inwards hanging position;
a guide weight roller arrangement including at least one guide weight roller which is insertable into a bend reversal region of the hose bend for rotary motion about a roller rotational axis, wherein the guide weight roller with its roller rotational axis is capable of translational motion in a hose bend lengthwise direction box-outwards with decreasing hose bend length and box-inwards with increasing hose bend length; and
a roller blocking device which releases the guide weight roller in its translational motion in a roller release condition and blocks the guide weight roller against further movement at least in a box-outwards direction beyond a roller blocking position in a roller blocking condition, wherein the roller blocking position is spaced box-inwards from a box-outwards end position of the guide weight roller, the box-outwards end position corresponding to a minimum hose bend length wherein the roller blocking device comprises:
a pivotable pivot lever which extends from a box-outwards actuating end on an operating side of the hose guiding box to a box-inwards blocking section and is pivotable between a blocking element release position and a blocking element blocking position, the blocking section of the pivot lever in the blocking element blocking position engages in a blocking manner in a roller rotational axis guiding path of the guide weight roller so as to block the guide weight roller with its rotational axis against said translational motion along the roller rotational axis guiding path in the hose bend lengthwise direction; or
a rotatable threaded control rod and a blocking element movable by the rod between a blocking element release position and a blocking element blocking position, the threaded control rod extending from a box-outwards actuating end on an operating side of the hose guiding box to a box-inwards threaded section and the blocking element cooperating with the box-inwards threaded section of the threaded control rod; or
an axially movable control rod and a blocking element movable by the rod between a blocking element release position and a blocking element blocking position, the control rod extending from a box-outwards actuating end on an operating side of the hose guiding box to a box-inwards control section, and the blocking element cooperating with the box-inwards control section of the control rod, and, in the blocking element blocking position, engaging in a blocking manner in a roller rotational axis guiding path of the guide weight roller.

7. The pull-out hose guiding device according to claim 6 , wherein the roller blocking device comprises the rotatable threaded control rod and the blocking element or the axially movable control rod and the blocking element; and wherein the blocking element comprises a blocking bolt which, in the blocking element blocking position, engages in a blocking manner in a roller rotational axis guiding path of the guide weight roller.

8. The pull-out hose guiding device according to claim 6 , wherein the roller blocking device comprises the rotatable threaded control rod and the blocking element or the axially movable control rod and the blocking element and wherein the blocking element comprises a blocking log which, in the blocking element blocking position, abuts in a blocking manner against a roller surface of the guide weight roller.

9. The pull-out hose guiding device according to claim 6 , wherein the pull-out hose guiding device is configured to guide a pull-out hose of a sanitary shower.

10. The pull-out hose guiding device according to claim 6 , wherein the roller blocking position is a box-inwards end position of the guide weight roller or has a distance from the box-inwards end position that is at most as great as half the distance of the box-inwards end position from the box-outwards end position of the guide weight roller.

11. The pull-out hose guiding device according to claim 6 , wherein the pull-out hose guiding device is configured to guide a pull-out hose of a sanitary shower.

12. A sanitary shower, comprising:
a shower head unit;
a pull-out hose to which the shower unit is coupled, the pull-out hose having at least one hose bend of variable hose bend length; and
a pull-out hose guiding device for guiding the pull-out hose, the pull-out hose guiding device comprising:
a hose guiding box configured for accommodating the hose bend in an anti-twist manner in a box-inwards hanging position;
a guide weight roller arrangement including at least one guide weight roller which is insertable into a be
