Description

[0001] The invention relates to a fountain attachment for water features with an adjustable nozzle for generating dynamic water patterns. Fountain attachments according to the preamble of claim 1 comprise at least one outer nozzle tube and an inner nozzle body, between which interaction can occur, so that the resulting water pattern can vary in various forms, from a fairly compact full jet to a fan-like or cup-shaped water pattern. Such fountain attachments are known, for example, from DE 10 2018 119 424 A1 or DE 2013 005 972 A1.

[0002] The invention is based on the object of creating a fountain attachment that enables water patterns with even greater variation. This object is achieved by a fountain attachment having the features of claim 1.

[0003] Using an effect attachment featuring a plurality of perforations, particularly perforations with a radial directional component, a cup-shaped water jet or a funnel-like water pattern is divided into individual jets. This requires at least one effect attachment, which is firmly connected to the outer nozzle pipe of the fountain attachment in the area of ​​the nozzle outlet. While the connection is fixed during normal use, it should be detachable. This allows one effect attachment to be exchanged for another, which, through a different design, particularly of the perforations, enables different water patterns.

[0004] The effect ring can preferably be connected to the outer nozzle tube by screwing it onto it, with screwing comprising several alternatives, such as an internal thread in the effect ring or an external thread on the effect ring interacting with an internal thread in the outer nozzle tube or also plug-in rotating connections such as a bayonet lock. All types of connections, including a plug-in connection, can be secured using pins or lateral fixing screws, for example. In a technically simple manner that is easy to handle for replacement, the effect ring can be designed in particular like a union nut. The effect attachment can essentially close the nozzle at the top at the nozzle outlet. However, it can also be designed as an effect ring. In this case, the effect-producing openings are then arranged in particular in the ring rim. Some or all of the openings can be open towards the water outlet side.

[0005] The effect attachment or the effect attachments used can be designed very differently, depending on which water images are to be created. For example, the openings in the effect attachment can be of different sizes and / or shapes, even within one effect attachment. It is also possible for the openings in the effect attachment to have different heights, for example, alternating between a lower and a higher opening. It is also possible for the openings to be located at different heights on the effect attachment in the longitudinal direction of the nozzle, in particular alternating. For example, one opening can be arranged in the upper area of ​​the effect attachment and be open at the top, while the adjacent opening extends into a lower area like a tunnel or bridge passage.All variations of perforations can be combined in a single effect element or in different effect elements. A spatial reference to "top" always refers to the water outlet side of the nozzle or to the top side if the nozzle is positioned vertically.

[0006] In one embodiment of the effect attachment, the openings can be spaced apart by separating elements that taper radially inward toward the center of the nozzle outlet. The separating elements or separating webs can preferably be designed to be aerodynamically favorable so that the water jet is divided with low friction. Jet guide elements can be connected to the separating elements, directed radially outward. These can help ensure that a sharp division of the water jet in the jet direction is maintained for a long time. The jet guide elements can also be designed like scoops and, if desired, can thus direct the individual jets even more strongly in a predetermined direction.

[0007] The attachment connected to the outer nozzle tube can completely span the nozzle at its outlet. It is also possible to arrange an effect attachment, also firmly but detachably connected to the inner nozzle body in the area of ​​the nozzle outlet. This effect attachment, in turn, has a plurality of openings that, in this case, divide a central water jet into several individual jets. This can be an additional effect attachment; however, it can also be formed integrally with the first effect attachment connected to the outer nozzle tube.

[0008] The effect attachment connected to the inner nozzle body can be a nozzle plate with perforations extending longitudinally along the nozzle. The perforations can vary in diameter, both from one perforation to another and within a perforation itself. If the perforations taper toward the water outlet side, the emerging water jets are even more concentrated.

[0009] The fountain attachment according to the invention can also be provided with an effect attachment designed as a rotating nozzle. The effect attachment has outlet channels directed at least substantially radially outward relative to the nozzle's longitudinal axis. This means that, with a vertical nozzle's longitudinal axis, these outlet channels have a distinct horizontal component, causing the water jets to be deflected substantially horizontally. Particularly in conjunction with a rotating nozzle, this creates an interesting, spiral-shaped water pattern. Such a rotating nozzle is preferably designed to be closed in the nozzle's longitudinal direction, preventing central water discharge and deflecting all escaping water to the side.

[0010] In a preferred embodiment, the outlet channels are each inclined or slanted relative to a radial plane perpendicular to the nozzle's longitudinal axis. Thus, the escaping water does not spray out of the nozzle in a precisely radial direction, but rather creates a compass rose effect even without rotating the nozzle itself.

[0011] Fountain attachments with rotating nozzles according to the invention can be used particularly in conjunction with pivoting drives for fountain attachments, such as those described in DE 10 2008 018 118. The entire fountain attachment can be set in rotation. Independently of this, it is also possible to design the effect attachment in such a way that it is mounted rotatably. In this case, the arrangement of the outlet channels causes the effect attachment to rotate automatically when exposed to the water jet supplied to the nozzle.

[0012] The fountain attachment with effect attachment according to the invention advantageously complements the selected adjustable nozzle to form a multifunctional nozzle with variable water patterns. Adjusting the nozzle by moving the outer nozzle tube relative to the inner nozzle body in the longitudinal direction of the nozzle is particularly advantageous, especially if this displacement is achieved by rotating the outer nozzle tube around the inner nozzle body using a guide contour with complementary guide elements. The guide bodies translate the rotation of the outer nozzle tube into a coaxial displacement. Because the effect attachment is also connected to the outer nozzle tube, this also rotates, and thus also the water pattern of the individual jets divided by it. A multitude of variable water patterns can be created in this way.

[0013] The fountain attachment according to the invention can also be used advantageously in conjunction with adjustable nozzles, in which an inner and an outer nozzle tube are supplied with water by two independently controllable pumps. The independent water supply to the inner and outer nozzle tubes, in conjunction with an effect attachment, creates variable water patterns.

[0014] Especially in large fountain shows, many different water patterns can be created by using different effect attachments, even when using only one basic nozzle model.

[0015] Further advantages and details emerge from the subclaims and the embodiments shown in the drawings; they show: Fig. 1 shows a fountain attachment according to the invention in a perspective view, Fig. 2a to e show various effect attachments in a perspective view, Fig. 3a and e show sections through the effect attachments of the Fig. 2a und e , Fig. 4 a longitudinal section through the object Fig. 1 , Fig. 5the object from Fig. 4 in another adjustment position of the nozzle, Fig. 6 the object from Fig. 4 with indicated water image, Fig. 7 the object from Fig. 5 with suggested water pattern, Fig. 8a fountain attachment similar Fig. 5 , but with an alternative adjustable nozzle and Fig. 9 a fountain attachment according to the invention in perspective view with opposite Fig. 1 different effect attachment.

[0016] The illustrations merely represent exemplary embodiments of the invention. The invention is in no way limited to them. Where possible and appropriate, corresponding components in the figures are provided with identical reference numerals, although not all components are identified in every figure.

[0017] The Fig. 1 The fountain attachment shown is provided with an effect attachment 1 designed as an effect ring and an effect attachment 2 designed as a nozzle plate in the area of ​​its nozzle outlet. Details on the function of the adjustable nozzle will be explained later using the sectional views in the Fig. 4 bis 7 described.

[0018] In the embodiments according to the Fig. 1 As shown in Figures 4 to 8, the effect attachment 1, designed as an effect ring 1, is screwed onto an outer nozzle tube 3. The nozzle tube 3 has an external thread at its upper end, while the effect ring 1 has a corresponding internal thread. In the illustrated embodiment, the effect attachment 2, designed as a nozzle plate 2, is screwed to an inner nozzle body 5 via a central bore 4.

[0019] The Fig. 2 and 3 show different effect rings 1A to 1D and an effect attachment 2 as a nozzle plate 2. All shown effect elements 1,2 have a plurality of openings 7, which divide a water jet into individual jets (see Fig. 6 and 7). These openings 7 can be designed very differently, as the effect attachments 1, 2 show. Thus, the openings 7 can have, among other things, different sizes, different heights and different positions within the effect attachment 1, 2. For example, in the effect attachment 1A, the openings 7 are differently shaped and of different heights. Thus, as shown particularly in Fig. 3A As can be seen, for every second opening 7" there is a ramp-like element 8, through which the height of the opening 7" is lower than that of the adjacent opening 7'. The ramp-like element 8 directs a water jet passed through the opening 7" further upwards than the adjacent water jet passing through one of the openings 7'.

[0020] In the effect ring 1B, the openings 7 are designed differently. The openings 7 are approximately the same size all the way around, but are arranged at different heights. While ramp-like elements 8 lead to the openings 7‴, which are open at the top, the openings 7"" extend beneath bridge-like separating elements 9, thus creating water jets below the water jets released by the openings 7‴.

[0021] The effect rings 1C and 1D generate uniform individual jets across their entire circumference, the jet heights of which do not differ as with the effect rings 1A and 1B. For this purpose, the effect rings 1C and 1D have separating elements 9 arranged in a slat-like manner around the circumference. They taper radially inward towards the center Z of the nozzle outlet and, in the illustrated embodiments, are also designed with flow-optimized radii. On the outer sides of the separating elements 9, viewed from the center Z, in the illustrated embodiments 1C and 1D, these merge into jet guide elements 10, which provide better guidance for the resulting individual jets. These jet guide elements 10 can also extend downwards in some areas beyond the outer circumference of the fastening area of ​​the effect ring 1, as shown.

[0022] The Fig. 2e and 3eshow an effect attachment 2 designed as a nozzle plate 2, which is penetrated by a plurality of openings 7 in the nozzle longitudinal direction L, ie parallel to the nozzle longitudinal axis D. In analogy to the effect rings 1, the openings 7 are also here for Fig. 3e larger towards the lower water inlet side and taper towards the Fig. 3e upper water outlet side. This results in both a more even water inlet and a focused jet outlet. Centric in Fig. 3e the hole 4 is visible, through which the nozzle plate 2 is fixed to the inner nozzle body 5 by means of a screw, as shown in the Fig. 4 bis 8 shown.

[0023] The Fig. 4 bis 7 show the fountain attachment in longitudinal section. In this embodiment, the nozzle is fundamentally adjustable by its outer nozzle tube 3 being displaced relative to an inner nozzle tube 13 containing the inner nozzle body 5. This displacement movement is initiated by the inner nozzle tube 13 being rotated by a belt pulley 14. The inner nozzle tube 13 has two guide contours in its outer wall that extend in a wave-like manner over its outer circumference, in which ball modules 15 slide as counter guide elements, which in turn are connected to the outer nozzle tube 3 and also raise and lower the outer nozzle tube 3 in a wave-like manner relative to the inner nozzle tube 13, i.e. translate the rotational movement into a coaxial displacement. The basic nozzle essentially corresponds to a design as shown in DE 10 2018 119 424 A1.

[0024] The Fig. 4 and 6represent the fountain attachment with the outer nozzle pipe 3 in the maximum raised position, whereby the water jets divided by the effect ring are quite flat. Fig. 5 and 7 In contrast, the outer nozzle tube 3 is in the lowest position relative to the inner nozzle tube 13, so that the outer individual jets can emerge high upwards.

[0025] Fig. 8 shows another embodiment of the base nozzle of a fountain attachment according to the invention in a sectional view as in Fig. 4 . In the embodiment of the Fig. 8 A variable water feature nozzle similar to the design in DE 10 2013 005 972 A1 is used as the base nozzle. In addition to the choice of effect ring 1 and effect element 2, a variety of water patterns can be created by varying the water supply and water pressures at the independently controllable pumps, which feed the completely separate pump connections 17 and 18.

[0026] Fig. 9 shows another opposite Fig. 1 A different embodiment of the fountain attachment according to the invention. In this embodiment, the effect attachment 1 is designed as a rotating nozzle with outwardly directed outlet channels 20. These can extend radially outwards or, as in the illustrated embodiment, in Fig. 9shown inclined relative to a radial R. In the illustrated embodiment, this inclination is at an angle α. Said inclination is intended to be projected onto an imaginary plane perpendicular to the nozzle's longitudinal axis D. Embodiments in which the outlet channels 20 do not extend perpendicular to the nozzle's longitudinal axis are also included. Furthermore, the outlet channels 20 can be configured not only linear and conical or cylindrical, as shown here, but also curved.

[0027] The fountain attachment according to the invention enables the creation of extremely diverse and dynamic water patterns with just a few basic elements by combining a variable water feature nozzle with individually selectable effect attachments designed according to the invention.
