Water feature for generating an illuminated water image

Abstract

A water feature for generating an illuminated water image has a housing and an illumination unit fixedly arranged in the housing. A water channel passes through the housing. A nozzle insert is disposed in the water channel and is designed to create a water image. The nozzle insert is supported so as to be pivotable relative to the illumination unit. The nozzle insert is supported so as to be pivotable about a pivot point, wherein the pivot point is positioned at a same level with or below a light-emitting top side of the housing. An alignment and fixation tool is provided that has first contact elements designed to engage second contact elements of a securing element that secures the nozzle insert so that the securing element can be released or fixed by rotation of the tool.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) Parts that act in the same or a similar way are provided with identical reference characters, if expedient.

(8) Individual technical features of the embodiments described in the following can also be combined in combination with the afore described embodiments as well as the features of the independent claims and dependent claims to subject matter in accordance with the invention.

(9) FIG. 1 shows a water feature 2 according to the invention in a cross section view. The water feature 2 comprises an illumination unit that is fixedly arranged in the housing 4 and is comprised of a plurality of LED (LED=light-emitting diode) groups 6; the water feature 2 further comprises a water channel 8 which is centrally passing through the housing 4. The water channel 8 is provided with a nozzle insert 10 for producing a water image. The housing 4 comprises a core housing 4a, a housing cover 4b, as well as glazing 4c. The light-emitting side of the housing 4 where the light exits represents its top side 12. The nozzle insert 10 is supported so as to be pivotable relative to the illumination unit, fixedly arranged in the housing 4, about a pivot point that is positioned below the top side 12 of the housing 4.

(10) The housing 4 is preferably embodied as an installation housing that in the installed position is mostly recessed in a receiving structure, for example, a flooring.

(11) The housing 4 forms a nozzle receptacle in such a way that the nozzle insert 10 is accommodated completely in the housing 4 in the installation position illustrated here. For this purpose, the nozzle insert 10 is inserted from the top side 12 into the water channel 8 and is secured at the housing 4 by a securing element 16 that engages at least partially around the nozzle insert 10. Here, the securing element 16 is in the form of a securing ring which can be screwed into the housing 4. The securing element 16 in the installed state is substantially flush with the top side 12, i.e., it projects only minimally past the top side 12. The nozzle insert 10 comprises a planar top side 10a. In the here illustrated coaxial pivot position in which a nozzle center axis B of the nozzle insert 10 is coaxial with the water channel center axis A of the water channel 8, it is arranged to be flush with the top side 12. In this pivot position, the nozzle insert 10 is also projecting by the least amount past the top side 12.

(12) FIG. 1 also shows that the nozzle insert 10 forms together with the housing 4 a joint with a spherical segment-shaped guide contour 18. The spherical segment-shaped guide contour 18 is formed by an outer contour of the nozzle insert 10 and is positioned at a centering inner surface 20 of the securing element 16. The centering inner surface 20 is embodied in a complementary shape to correspond to the spherical segment-shaped guide contour 18. The housing 4 comprises also a flange insert 22 which can be screwed from the bottom side 24 into the housing 4. The flange insert 22 comprises a conical bearing contour 26 on which the nozzle insert 10 is supported.

(13) On a circumferential region of its spherical segment-shaped outer contour, the nozzle insert 10 comprises a guide projection 28 which is extending completely about the circumference and engages the guide receptacle 30 of the housing 4 for limiting the pivot movement of the nozzle insert 10. The guide receptacle 30 is formed by the water channel 8 itself and is delimited from below by the flange insert 22 and from above by the securing element 16.

(14) The available movement range of the pivot movement of the nozzle insert 10 is limited by the clearance that the guide projection 28 has in the guide receptacle 30.

(15) FIG. 2 shows a set according to the invention of a water feature 2 and an alignment and fixation tool 32. The alignment and fixation tool 32 comprises in circumferential direction about its centrally extending tool axis of rotation C four tool-associated contact elements 34 of which only three are visible here. The tool-associated contact elements 34, which are embodied in the form of projections extending in the direction of the water channel center axis A, are embodied in a complementary shape relative to four water feature-associated contact elements 36 of the securing element 16, which are in the form of recesses extending in the direction of the water channel center axis A and of which only two are visible here. The complementary configuration is such that the tool-associated contact elements 34 and the water feature-associated contact elements 36 can be brought into a form fit engagement or a form fit position. In this form fit position, the securing element 16 can be fixed or released by rotation of the alignment and fixation tool 32 about the tool axis of rotation C that is then parallel to the water channel center axis A.

(16) FIG. 3 shows the alignment and fixation tool 32 in a plan view. The alignment and fixation tool 32 comprises two grip elements 38, which extend transversely to its tool axis of rotation C that in this illustration extends perpendicularly to the image plane. The grip elements 38 are positioned opposite each other and enable a comfortable one-hand operation. Each of the grip elements 38 comprises in addition an engagement region 40, here in the form of a continuous cutout, for engagement of a lever enlarging element. In this way, for increasing the leverage action as needed, one or a plurality of lever enlarging elements, for example, in the form of a lever extension, can be applied to the engagement regions 40.

(17) For optimal alignment of the nozzle insert 10 and/or of the housing 4, the alignment and fixation tool 32 comprises a circular level 42 which is clipped removably into one of the grip elements 38.

(18) FIG. 4 shows the water feature 2 and the alignment and fixation tool 32 in a plan view in which the tool-associated contact elements 34 have been brought into form fit engagement or into the form fit position with the water feature-associated contact elements 36. By rotation of the alignment and fixation tool 32 in the rotational direction D about the tool axis of rotation C, the securing element 16 can be released or fixed.

(19) FIG. 5 shows the water feature 2 in plan view with the circular level 42 placed onto the planar top side 10a of the nozzle insert 10 which is precisely horizontally aligned; this is indicated by the central position of the gas bubble of the circular level 42.

(20) The specification incorporates by reference the entire disclosure of German priority document 10 2020 101 238.1 having a filing date of Jan. 20, 2020.

(21) While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
