Definitions
- the invention relates to a built-in element for receiving and attaching an underwater spotlight for water-filled pools, as is specified in the preamble of claim 1.
- the underwater spotlight can be used in mineral water or brine baths.
- Such built-in elements are usually already concreted in during the manufacture of the pool wall or the pool floor, that is to say with tiles even before the pool is lined.
- this is not only visually unsatisfactory, but also entails a considerable additional workload, since generally more tiles have to be cut and adapted than would be the case with a symmetrical installation.
- the cable for the power supply of the underwater spotlight is usually led through an empty conduit, which is pre-cast into the wall or the floor of the basin as far as the installation element. There it enters the installation element through a sealing cable gland and is finally connected to the underwater spotlight.
- This cable gland is of course also subject to the corrosive effect of the water or the brine in the interior of the flooded installation element.
- rubber sealing rings used for the actual sealing lose their sealing effect over time due to aging and embrittlement processes. If the installation element is flooded with brine, these processes are of course accelerated considerably.
- the present invention seeks to remedy these disadvantages.
- the invention has the task of extending the life of a built-in element for underwater spotlights by the fact that the seal - especially in the cable duct - that
- the built-in element according to the invention should make it possible for the underwater spotlight not to impair the water quality of the pool and to always fit into the tile grid of the pool in a visually appealing and symmetrical manner.
- the object is achieved in particular in that pure water can flow through the installation element.
- it is not, as is generally customary, only a conduit that conducts cables through the wall or the bottom of the basin to the installation element, but a supply conduit that conducts both water and water is integrally connected to the installation element according to the invention.
- a cemented cable screw connection which is concreted in and adjoins the installation element.
- the dual function of the supply pipe according to the invention - pure water supply and cable routing - ensures that the power cable is cooled over the entire length of the pipe. With the end opposite the installation element, the feed pipe opens into a drying or maintenance room.
- a sealing plug for example a rubber sealing ring, is pressed by a pressure screw with an external thread and an axial bore, the internal diameter of which corresponds approximately to the cable diameter, against the shoulder at the foot of the bore of larger diameter.
- the external thread of the pressure screw interacts with an internal thread provided in the larger diameter bore.
- Downstream of the stopper is a pipe with for the introduction of pure water Pure water connection welded to the supply pipe by pipe welding.
- the cable and water connection at the end of the supply pipe can be more easily installed by using a T-piece.
- the feed pipe itself is screwed or even integrally glued via a pipe thread.
- the above-described sealing plug with cable entry is screwed or glued and inserted into the third arm of the Finally, the T-piece opens the pipe through which pure water is fed into the feed pipe. This transition is of course also sealed by a pipe screw connection or by gluing.
- the installation element according to the invention is initially concreted into the wall or floor of the basin, more or less exactly positioned.
- the position of the underwater spotlight in the built-in element is not predetermined from the outset, as in conventional models of the prior art (through prefabricated threaded bores for fastening the underwater spotlight in the built-in element).
- it is rather also possible to use the underwater spotlight to a certain extent To fix the installation tolerance in the installation element and thus compensate for any inaccurate positioning of the installation element in the concrete wall or floor.
- the underwater spotlight can always be optimally fitted symmetrically into the tile grid of the pool, so that both a visually appealing appearance is created and the adaptation and cutting work on the tiles can be minimized.
- a base which can be fastened to the inner bottom of the built-in element and on which the underwater spotlight is mounted either directly or via a known rotating bracket.
- this base In order to ensure an installation tolerance in the plane of the pool wall or floor, this base must of course first be displaceable in a plane parallel to this plane on the floor of the installation element. For this purpose, it has a groove into which a bolt which is firmly anchored in the center of the base of the installation element projects.
- the base can consequently be displaced along this bolt by guiding the groove on the bottom of the built-in element. It is particularly advantageous to make this groove T-shaped in section and to use a threaded bolt, since in this way, in addition to being displaceable, the base can also be fixed in a certain position. As soon as the installation element and thus the base is in its optimal position, the base can be fastened by screwing a nut onto the threaded bolt and then tightening it against the shoulder of the T-shaped groove. The same naturally also applies to the use of a screw which is seated, for example, in a threaded hole formed in the center of the base plate. In order to ensure the practical feasibility of this fastening, however, the base must be constructed in two parts.
- the height of the housing body of the installation element must also be adjustable in order to achieve a vertical installation tolerance.
- the base plate essentially consists of a jacketed, cylindrical or prismatic tube section, an annular base flange, an annular press flange and a further tube section. While the dimensions of the first three components are specified, the length of the closing pipe section, on the free end of which the underwater spotlight with a radially molded flange finally comes to rest, is always dimensioned to achieve the maximum installation tolerance, so that the required section is shortened by shortening the pipe section Length can be obtained.
- the hermetic sealing of the flooded built-in element against the concrete wall or floor of the basin is achieved in that all components of the built-in element both with one another and with the sealing film guided between the concrete wall or floor and the tile structure of the basin by gluing to form an integral sandwich composite are connected. These connections between the individual components or the sealing film are to be explained in more detail below.
- the coated tubular section of the housing body directly adjoining the base plate of the built-in element is fitted with its front edge areas into complementary annular groove profiles in the axially inner surface of the base plate with a snug fit and is hermetically sealed.
- the radially outer circumferential surface of the sheathed tube section is flush with the surface and, in particular by gluing to form a sandwich, is enclosed by a tube collar, one end face of which is flush with the axially inner surface of the base flange and is also connected to it in a sandwich-like manner, in particular by gluing, during the latter the other end face is in flush contact with the axially inner surface of the base plate and is additionally integrally connected to it to form a sandwich-like composite.
- the cable and pure water supply pipe opens into the housing body.
- the feed pipe is also sealingly connected to the wall of the housing body by gluing or welding. It penetrates an inlet bore in the covered pipe section and a coaxial and congruent inlet bore in the pipe sleeve in such a way that the feed pipe forms a firm sandwich composite with the covered pipe section and the pipe sleeve.
- the sealing film of the basin to be placed between the base flange and the press flange and to be provided with a circular cutout with approximately the same radius as that of the installation element is already pressed between these two flanges in a compressive and sealing manner when the base flange and press flange are screwed together. It is particularly advantageous to make the circular cutout of the sealing film somewhat larger, so that it does not reach the radially inner edge of the annular base flange and the annular press flange at any point. The resulting annular disk-shaped space between the press and base flange can then be completely filled with an adhesive that extends to the inner surface of the two flanges. So are Base flange, press flange, and sealing film are integrally connected. This sealing connection can be made even more secure if a pipe socket is fitted into the housing body at the level of the base flange and press flange, since this fits through to the inner surfaces of the two shells
- Adhesive escaping flanges forms an integral sandwich composite, at least with the base and press flange.
- an integral sandwich bond can also be achieved in this way between the covered pipe section, base flange, press flange, final pipe section and fitted pipe socket.
- the fitted pipe socket is even connected with adhesive at two points.
- the adhesive emerging from the joint between the base flange and the press flange and on the other hand, however, also with the adhesive emerging from the joint between the press flange and the final pipe section onto the inside of the casing body.
- an additional annular sealing film cutout which comes with its radially outer area to rest on the actual sealing film of the basin and with its radially inner area as far as between the press flange and final pipe section is sufficient, and is integrally glued there with these two components.
- This additional annular sealing film cutout is of course also bonded radially on the outside to the actual sealing film. In this way, it covers the heads of the screws, which are recessed into the axially outer side of the press flange, and with which the press flange is screwed onto the base flange with the sealing film interposed.
- FIG. 2 shows a plan view of the fully assembled built-in element or of the underwater spotlight

- the adhesive 20 is shown blackened only in the left half of the drawing, and the pipe socket 18, which can optionally be fitted into the housing body 3, is shown.
- the housing body 3 is firmly anchored in a circular groove in the base plate 2 via the tube section 13 encased by a tube sleeve 14 and is integrally connected to the base plate 2 by gluing.
- the opposite end of the tube section 13 is also seated in a circular groove, which on the
- Pipe section 13 and pipe sleeve 14 are pierced by a coaxial and congruent inlet bore through which the feed pipe 4 enters the interior of the installation element 1 flows.
- Supply pipe 4, pipe section 13 and pipe sleeve 14 also form an integral sandwich composite by gluing.
- Base flange 15 and press flange 16 are initially only connected via a detachable screw connection 19, so that when installing the installation element 1, the sealing film 11 arranged between the pool wall or floor 9 and the tile structure 10 is arranged between the axially outer end face of the base flange 15 and the axially inner end face of the Press flange 16 can be inserted.
- the sealing film is hermetically sealed.
- the circular cutout in the sealing film 11 can have a larger diameter than the inside diameter of the housing body 3, so that the sealing film 11 does not touch the inner surface of the base or press at any point flange 15, 16 is sufficient and rather an annular disk-shaped joint between base flange 15 and press flange 16 remains.
- This can be filled with an adhesive 20 which penetrates as far as the inside of the two flanges and thus connects them together with the sealing film 11 to form an integral sandwich composite. If the pipe socket 18, which can optionally be fitted into the housing body 3, is also provided, this is also included in the integral sandwich composite by the adhesive 20.
- annular sealing film cutout 12 is provided for the sealing covering of the heads of the screws 19, which are sunk into the axially outer end face of the press flange 16 and serve for connection to the base flange 15. This comes to rest with its radially outer area on the sealing film 11 of the basin and with its radially inner area on the axially outer end face of the press flange 16. By gluing it is integrally connected radially on the outside with the sealing film 11 and radially on the inside with the press flange 16 and the subsequent pipe section 17. If the fitted pipe socket 18 is provided in a corresponding length, then it is also included in the radially inner connection by the adhesive bond.
- the pipe section 17, on its axial the outer end face of the underwater spotlight 6 with a radially outer flange 7 is already shortened to the length which is necessary to compensate for any irregularities in the installation depth of the base plate 12 in the wall or the floor 9 of the pool.
- the underwater spotlight 6 itself is fastened in the installation element 1 in that it is glued on the one hand to the axially outer end face of the closing pipe section 17 and, on the other hand, is fastened to the rotary bracket 8 by a screw connection shown in broken lines.
- the rotary bracket 8 is in turn fastened centrally on the component 23 of the base 21 via a screw connection.
- the component 23 is mounted on the component 22 of the base centered via a screw connection shown in dashed lines.
- the swivel bracket 8 and the underwater spotlight 6 can be turned around a screw 24 protruding from the center of the base plate 2 into the installation element 1 and moved into an eccentric position by guiding a T-shaped groove 29 formed radially in the component 22. In this desired
- the entire ensemble can be fixed in position by means of a screw 24 protruding from the center of the base plate 2 through the T-shaped groove 29.
- Fig. 1 the installation element 1 according to the invention is shown in the fully installed state.
- a mounting plate made of recycled material is screwed to the center of the base flange 15.
- placeholder for the components to be assembled later (see above). Therefore, the outline of the originally used mounting plate can still be clearly seen from the course of the concrete wall 9 sloping towards the base flange 15.
- the mounting plate preferably has a ventilation hole, which is helpful for checking the tightness of the installation element and the associated pure water-carrying pipe system.
- the ventilation hole remains open for the purpose of ventilation. For subsequent pressing, it is then closed with a stopper.
- the mounting plate After pressing, the mounting plate can be removed and the entire "structure" (see above) can be mounted over the base flange 15 or glued to the sealing foils 11, 12 of the basin.
- the 2 shows the built-in element 1 or the underwater headlight 6 which is only visible from the front in the installed state.
- the underwater spotlight 6 is fastened on the rotating bracket 8 by means of the two screws, the hexagonal heads of which are visible.
- Optimally symmetrical fitting of the headlamp into the tile grid is achieved through the adjustment options of the base 21.
- Fig. 3 shows the end of the supply pipe 4 opening into the drying or maintenance room in longitudinal section.
- the end of the feed pipe 4 is glued into one arm of a T-shaped pipe connection piece 28 and connected to it in a sealing manner.
- a sealing plug, which receives the sealing screw connection 26, is glued into the opposite tubular arm.
- the end of a tube 27 is glued into the third tube arm of the T-shaped connecting piece 28, which tube arm is oriented at right angles to these two tube arms and through which pure water is fed into the feed tube 4.
- the pressure screw is screwed from the drying chamber via an internal thread cut into the larger diameter bore of the sealing plug against the shoulder serving as a stop at the transition of the two bore diameters in the sealing plug.
- a rubber sealing ring inserted between the heel and pressure screw is pressed around the cable in a sealing manner.
- Both components 22 and 23 are cylindrical in shape.
- a T-shaped groove 29 is formed in the component 22 radially from the center point. For manufacturing reasons, this groove is designed as a flat groove with a rectangular cross section and extends radially beyond the axis of the component 22 as a continuation of the T-shaped groove.
- the base 21 again as an axial section and in a top view, the prefabricated bores for the later screw connections and the T-shape of the groove 29 being particularly clearly visible.
- the axially centered bore in the component 23 receives the screw for fastening the rotary bracket 8 during assembly. It is framed by two bores which, starting from the free end face of the component 23, taper in the interior of this component 23 to form a shoulder and extend with this tapered diameter into the component 22. The component 23 can be fastened on the component 22 by screwing over these two bores.
