Description

Die Erfindung betrifft eine Bodeneinbauleuchte nach dem Oberbegriff der Ansprüche 1 oder 12, nämlich eine Leuchte, die in eine Einbauöffnung des Bodens einbaubar ist.The invention relates to a ground light according to the preamble of claims 1 or 12, namely a lamp which can be installed in an installation opening of the soil.

Im Gegensatz zu einer Wand- oder Deckeneinbauleuchte hat eine Bodeneinbauleuchte besondere Anforderungen zu erfüllen. Eine erste Anforderung ist eine besondere Festigkeit, da die Bodeneinbauleuchte im Bereich der Einbauöffnung den Böden ersetzt und deshalb die erforderliche Tragfähigkeit aufweisen muss. Eine andere Anforderung besteht in einer besonderen Abdichtung der Bodeneinbauleuchte, um zu verhindern, dass Wasser aufgrund der Scherkraft in die Einbauleuchte einströmt.In contrast to a recessed wall or ceiling luminaire, a recessed ground luminaire has to fulfill special requirements. A first requirement is a special strength, since the recessed floor luminaire replaces the floor in the area of the installation opening and therefore must have the required load-bearing capacity. Another requirement is a special sealing of the recessed floor light, to prevent water from flowing into the recessed light due to the shearing force.

In der DE 199 18 872 A1 ist eine Bodeneinbauleuchte nach dem Oberbegriff des Anspruchs beschrieben. Diese vorbekannte Bodeneinbauleuchte weist einen einteiligen Einbaurahmen auf, der innenseitig in einem Abstand von seinem oberen Rand einen Innenflansch aufweist, auf dem ein Außenflansch eines Lampenträgers aufliegt und daran abgestützt ist. Auf dem Außenflansch ist ein Scheibendeckel abgestützt, wobei zwischen dem Außenflansch und dein Scheibendeckel eine Ringdichtung angeordnet ist. Bei der Ausgestaltung nach Fig. 1 ist ein vorhandener Dichtring zwar auch zwischen dem Scheibendeckel und den oberen Umfangsrand des Einbaurahmens wirksam, jedoch besteht die Gefahr, das Wasser von oben in den Einbaurahmen eindringen kann.In the DE 199 18 872 A1 a ground light is described according to the preamble of the claim. This known floor recessed luminaire has a one-piece mounting frame, which has on the inside at a distance from its upper edge an inner flange on which an outer flange of a lamp support rests and is supported thereon. On the outer flange a disc cover is supported, wherein between the outer flange and the disc cover an annular seal is arranged. In the embodiment according to Fig. 1 Although an existing sealing ring is effective between the disc cover and the upper peripheral edge of the mounting frame, but there is a risk that water can penetrate from above into the mounting frame.

Aus der EP 0849 525 A2 ist eine Bodeneinbauleuchte mit einem Einbaurahmen zu entnehmen, der in einem zugehörigen Einbauloch so tief angeordnet ist, das sein oberer Rand einen vertikalen Abstand vom oberen Rand des Einbaulochs aufweist. Ein Lampenträger ist auf einer Bodenwand des topfförmig ausgebildeten Einbaurahmens angeordnet. Diese Einbauleuchte weist mehrere übereinander angeordnete Scheibendeckel auf, von denen ein erster Scheibendeckel auf dem ebenfalls topfförmig ausgebildeten Lampenträger angeordnet und durch einen Dichtring abgedichtet ist. Ein darüber angeordneter Scheibendeckel ist auf einem Innenflansch des Einbaurahmens angeordnet und durch einen zugehörigen Dichtring abgedichtet. Ein weiterer Scheibendeckel ist auf dem oberen Rand des Einbaurahmens angeordnet. Bei dieser vorbekannten Einbauleuchte sind die Innenräume des Lampenhalters und des Einbaurahmens zwar durch die zugehörige Deckelscheibe abgedichtet, jedoch besteht die Gefahr, dass unter die oberste Deckelscheibe oder die obersten Deckelscheiben Oberflächenwasser eindringen kann, das den Lichtaustritt beeinträchtigt.From the EP 0849 525 A2 is to be taken from a recessed ground light with a mounting frame, which is arranged so deep in an associated mounting hole that has its upper edge a vertical distance from the upper edge of the mounting hole. A bulb holder is arranged on a bottom wall of the cup-shaped mounting frame. This recessed luminaire has a plurality of disc cover arranged one above the other, of which a first disc cover is arranged on the also cup-shaped bulb holder and sealed by a sealing ring. An arranged above disc cover is arranged on an inner flange of the mounting frame and by an associated sealing ring sealed. Another disc cover is arranged on the upper edge of the mounting frame. In this prior art recessed luminaire, the interiors of the lamp holder and the mounting frame are indeed sealed by the associated cover plate, but there is a risk that can penetrate under the top cover plate or the top cover discs surface water that affects the light emission.

Die US 4 924 364 offenbart eine Unterflurbeleuchtungseinrichtung mit einem Deckel bestehend aus einer transparenten Platte und einem diese umgebenden Flansch, welcher Hohlräume aufweist, um Dichtungselemente darin unterzubringen. Der Flansch ist in ein die Außenkanten des Rings umgebendes und die Außenkanten überragendes Gehäuse eingelassen.The US 4,924,364 discloses a underfloor lighting device with a lid consisting of a transparent plate and a surrounding flange, which has cavities to accommodate sealing elements therein. The flange is embedded in a surrounding the outer edges of the ring and the outer edges superior housing.

Der Erfindung liegt die Aufgabe zu Grunde bei einer Bodeneinbauleuchte der eingangs angegebenen Arten die Abdichtung gegen das Eindringen von Wasser zu verbessern. Dabei soll im weiteren eine einfach und kostengünstig herstellbare Ausgestaltung gewährleistet sein. Es ist auch angestrebt, eine solche Ausgestaltung zu finden, die eine einfache und handhabungsfreundliche Montage beziehungsweise Demontage ermöglicht.The invention is based on the object with a ground light of the types specified to improve the seal against the ingress of water. It should be ensured in a further simple and inexpensive to produce design. It is also desirable to find such a design that allows a simple and easy to handle assembly or disassembly.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 oder 11 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den zugehörigen Unteransprüchen beschrieben.This object is solved by the features of claim 1 or 11. Advantageous developments of the invention are described in the appended subclaims.

Bei der erfindungsgemäßen Einbauleuchte nach Anspruch 1 ist zwischen der Innenumfangsfläche des Einbaurahmens und der Außenumfangsfläche des Flansches und/oder zwischen der Schulterfläche und den Flansch ein erster Dichtring angeordnet. Bei dieser erfindungsgemäßen Einbauleuchte ist nicht nur der Scheibendeckel sondern auch die zwischen der Schulterfläche des Einbaurahmens und dem Flansch vorhandene Fuge abgedichtet. Dies kann durch einen zwischen der Schulterfläche und dem Flansch angeordneten ersten Dichtring und/oder einen zwischen der Innenumfangsfläche des Einbaurahmens und der Außenumfangsfläche des Flansches angeordneten ersten Dichtring erfolgen. Beide erfindurigsgemäßen Ausgestaltungen ermöglichen eine sichere Abdichtung zwischen dem Einbaurahmen und dem Flansch des Lampenträgers. Wenn jeweils ein Dichtring zwischen den Einbaurahmen und der Außenumfangsfläche des Flansches und zwischen der Schulterfläche und der Unterseite des Flansches angeordnet sind, ist auch dann die Abdichtung gewährleistet, wenn eine dieser beiden ersten Dichtringe beschädigt sein sollte oder beschädigt werden sollte.In the recessed luminaire according to the invention according to claim 1, a first sealing ring is arranged between the inner peripheral surface of the mounting frame and the outer peripheral surface of the flange and / or between the shoulder surface and the flange. In this recessed luminaire according to the invention not only the disc cover but also the existing between the shoulder surface of the mounting frame and the flange gap is sealed. This can be done by a arranged between the shoulder surface and the flange first sealing ring and / or arranged between the inner peripheral surface of the mounting frame and the outer peripheral surface of the flange first sealing ring. Both inventive embodiments allow a secure seal between the mounting frame and the flange of the lamp holder. If in each case a sealing ring between the mounting frame and the outer peripheral surface of the flange and between the shoulder surface and the underside of the flange are arranged, the seal is ensured even if one of these two first sealing rings should be damaged or damaged.

Ein winkelförmiger erster Dichtring eignet sich besonders gut, weil die vorgenannten Vorteile durch einen gemeinsamen Dichtring erreicht werden, der sich in einfacher weise herstellen, handhaben und montieren lässt.An angular first sealing ring is particularly well, because the aforementioned advantages are achieved by a common sealing ring, which can be produced in a simple manner, handle and assemble.

Eine zwischen dem Flansch und dem Scheibendeckel angeordnete Ringdichtung ist im Rahmen der Erfindung durch einen zweiten Dichtring gebildet, der vorzugsweise winkelförmig oder U-förmig ausgebildet ist, so dass er sich nicht nur an der Unterseite des Scheibendeckels erstreckt sondern winkelförmig seinen Umfangsrand übergreift oder U-förmig hintergreift.A arranged between the flange and the disc cover ring seal is formed in the invention by a second sealing ring, which is preferably angular or U-shaped so that it not only extends to the underside of the disc cover but angularly engages over its peripheral edge or U- engages behind formally.

Es ist aus mehreren Gründen vorteilhaft den Einbaurahmen mit einem unteren Einbaubasisrahmen und einem oberen Aufnahmerahmen zweiteilig auszubilden und den oberen Aufnahmerahmen auf den Einbaubasisrahmen abzustützen. Hierbei ist es besonders vorteilhaft, den Scheibendeckel im Aufnahmerahmen zu lagern. Diese Ausgestaltung ermöglicht auch eine voreinander unabhängige Montage der Einbaurahmenteile.It is advantageous for two reasons to design the mounting frame in two parts with a lower mounting base frame and an upper mounting frame and to support the upper mounting frame on the mounting base frame. It is particularly advantageous to store the disc cover in the receiving frame. This embodiment also allows an independent installation of the mounting frame parts.

Die Einbaurahmenteile können direkt oder mittels eines oben im Einbaurahmen angeordneten und sich auf dem Scheibendeckel abstützenden Abschlussringes verschraubt sein beziehungsweise verschraubt werden. Hierdurch wird der Einbaurahmen nicht nur stabilisiert, sondern es erfolgt auch eine Verbindung des oberen Aufnahmerahmens mit den Einbaubasisrahmen, so dass letzterer stabil positioniert ist. Außerdem lässt sich durch eine Verschraubung des oberen Aufnahmerahmens gegen den unteren Einbaubasisrahmen die Abdichtung verbessern.The mounting frame parts can be screwed or screwed directly or by means of a top arranged in the mounting frame and be supported on the disc cover end ring. As a result, the mounting frame is not only stabilized, but there is also a compound of the upper mounting frame with the mounting base frame, so that the latter is stably positioned. In addition, the seal can be improved by screwing the upper mounting frame against the lower mounting base frame.

Bei der erfindungsgemäßen Bodeneinbauleuchte nach dem unabhängigen Anspruch 11 besteht der Einbaurahmen aus einem Einbaubasisrahmen und einem Aufnahmerahmen, wobei der Aufnahmerahmen mit dem oberen Randbereich des Einbaubasisrahmens lösbar verbunden oder verbindbar ist und durch einen ersten Dichtring abgedichtet ist, wobei der Scheibendeckel am Aufnahmerahmen gehalten und abgedichtet ist.In the ground recessed luminaire according to the invention according to independent claim 11, the mounting frame consists of a mounting base frame and a receiving frame, wherein the receiving frame with the upper edge region of the mounting base frame is detachably connected or connectable and sealed by a first sealing ring, wherein the disc cover is held and sealed to the receiving frame ,

Die erfindungsgemäße Ausgestaltung umfasst drei wesentliche Bauteile, die aufgrund ihrer Bauform einfach und preiswert herstellbar sind, eine stabile Konstruktion ergeben und sich in einfacher Weise abdichten lassen. Hierzu kann ein erster Dichtring vorgesehen sein, der mit elastischem Druck axial und/oder radial zwischen den Teilen wirksam ist. Dabei kann der Lampenträger z.B. mit einem Flansch ebenfalls am Aufnahmerahmen gehalten und durch den axial und/oder radial dazwischen wirksamen Dichtring abgedichtet sein.The inventive design comprises three essential components that are simple and inexpensive to produce due to their design, give a stable construction and can be sealed in a simple manner. For this purpose, a first sealing ring can be provided, which is effective with elastic pressure axially and / or radially between the parts. In this case, the bulb holder may e.g. also held with a flange on the receiving frame and sealed by the axially and / or radially effective between sealing ring.

Ein weitere Vorteil besteht darin, dass der Einbaurahmen ein durch den Aufnahmerahmen gebildetes Einbaurahmen-Oberteil aufweist, das lösbar mit einem durch den Einbaubasisrahmen gebildeten Einbaurahmen-Unterteil verbunden ist. Hierdurch ist es möglich, den Einbaubasisrahmen als Verankerungsteil für den Aufnahmerahmen zu benutzen. Bei einer Beschädigung z.B. des oberen Randes des Aufhahmerahmens muss nicht der gesamte Einbaurahmen ausgebaut und repariert bzw. ersetzt werden, sondern es braucht nur der Aufnahmerahmen ausgebaut, repariert oder ersetzt werden.Another advantage is that the mounting frame has a housing frame formed by the receiving frame upper part, releasably with a connected by the mounting base frame mounting frame base is connected. This makes it possible to use the installation base frame as an anchoring part for the receiving frame. In case of damage, for example, the upper edge of the mounting frame not the entire mounting frame must be removed and repaired or replaced, but it needs only the receiving frame removed, repaired or replaced.

Ein weiterer Vorteil besteht darin, dass der Einbaubasisrahmen vorab im Boden eingebaut und verankert werden kann und der Aufnahmerahmen zum Abschluss der Baumaßnahmen montiert werden kann, wobei er vor Beschädigungen durch die Baumaßnahmen geschont werden kann.Another advantage is that the installation base frame can be installed and anchored in advance in the ground and the receiving frame can be mounted to complete the construction, where it can be protected from damage by the construction.

In den Unteransprüchen sind Merkmale enthalten, die ebenfalls bei Gewährleistung einer einfachen und kostengünstigen Herstellung sowie der erforderlichen Stabilität und Abdichtung eine einfache Montage bzw. Demontage gewährleisten. Weitere Merkmale der Unteransprüche verbessern die Montage bzw. Demontage und die Befestigung des Aufnahmerahmens und der Abdeckscheibe.In the subclaims include features that also ensure a simple assembly and disassembly while ensuring a simple and inexpensive production and the required stability and sealing. Further features of the dependent claims improve the assembly and disassembly and the attachment of the receiving frame and the cover.

Die in ihrer Gesamtheit mit 1 bezeichnete Bodeneinbauleuchte weist einen Einbaurahmen auf, der in einem Einbauloch 3 mit einer Lochöffnung 3a in einem Boden 2 mit einer Oberfläche 2a von oben eingesetzt und z.B. eingebettet ist. Die horizontale Querschnittsform des Einbaulochs 3 und der Bodeneinbauleuchte 1 kann gemäß Fig. 2 und 3 rund oder gemäß Fig. 4 bis 7 eckig sein, z.B. rechteckig oder quadratisch.The designated in their entirety by 1 recessed ground light has a mounting frame, which is used in an installation hole 3 with a hole opening 3a in a bottom 2 with a surface 2a from above and embedded, for example. The horizontal cross-sectional shape of the mounting hole 3 and the floor light 1 can according to FIGS. 2 and 3 round or according to Fig. 4 to 7 be square, eg rectangular or square.

Die Hauptbauteile der Bodeneinbauleuchte 1 sind ein Einbaubasisrahmen, der einteilig oder mit einem unteren Einbaubasisrahmen 4 und einem oberen Aufnahmerahmen 11 zweiteilig ausgebildet sein kann. Der Einbaubasisrahmen 4 ist in einem Abstand a von der Oberfläche 2a im Einbauloch 3 befestig, und er kann hierzu Mittel aufweist, mit denen er im Boden 2 verankerbar ist. Der Einbaubasisrahmen 4 ist vorzugsweise durch den oberen Rand eines Einbaugehäuses 4a mit einer Umfangswand 4b und einer Bodenwand 4c gebildet, der im Böden verankert ist, z.B. eingegossen ist. In seinem oberen Randbereich weist der Einbaubasisrahmen 4 wenigstens zwei einander gegenüberliegende Materialansätze 4d, 4e auf, in denen sich im wesentlichen parallel zur vertikalen Mittelachse 6 erstreckende Gewindelöcher 7, 8 angeordnet sind. Die Materialansätze 4d, 4e können einteilig angeformt sein oder zweiteilig ausgebildet sein und befestigt sein, z.B. angeformt oder angeschweißt oder angeklebt sein. Der Materialansatz 4e auf der in Fig. 1 rechten Seite des Einbaugehäuses 4a kann Teil einer vertikalen Sicke 9 der Umfangswand 4b sein. Die Sicke 9 bildet einen vertikal erstreckenden Freiraum, der auch bei einem im horizontalen Querschnitt runden Einbaugehäuse 4a eine unrunde Außenform ergibt, die eine formschlüssige Verankerung verbessert und eine formschlüssige Drehsicherung für das Einbaugehäuse 4a im Einbauloch 3 bildet.The main components of the recessed ground light 1 are a mounting base frame, which may be formed in one piece or with a lower mounting base frame 4 and an upper mounting frame 11 in two parts. The installation base frame 4 is fastened at a distance a from the surface 2a in the installation hole 3, and for this purpose it can have means with which it can be anchored in the floor 2. The mounting base frame 4 is preferably formed by the upper edge of a mounting housing 4a with a peripheral wall 4b and a bottom wall 4c, which is anchored in the ground, for example, is cast. In its upper edge region, the mounting base frame 4 at least two opposing material approaches 4d, 4e, in which substantially parallel to the vertical central axis 6 extending threaded holes 7, 8 are arranged. The material projections 4d, 4e may be integrally formed or be formed in two parts and fastened, for example, be molded or welded or glued. The material approach 4e on the in Fig. 1 right side of the mounting housing 4a may be part of a vertical bead 9 of the peripheral wall 4b. The bead 9 forms a vertically extending free space, which results in a non-circular outer shape even with a horizontal cross-section mounting housing 4 a, which improves a positive anchoring and forms a positive rotation lock for the mounting housing 4 a in the mounting hole 3.

Im Abstand a oberhalb des Einbaugehäuses 4a befindet sich der in der Umfangsrichtung durchgehend ausgebildete Aufnahmerahmen 11 mit einem im wesentlichen vertikalen Rahmenschenkel 11a und einem sich im wesentlichen horizontal erstreckenden Rahmenschenkel 11b, wobei die horizontale Querschnittsabmessung b des auf dem Einbaubasisrahmen 4 sitzenden Aufnahmerahmens 11 gleich oder größer ist als die horizontale Querschnittsabmessung des Einbaubasisrahmens 4 bzw. des Einbaugehäuses 4a an seinem oberen Rand. Insbesondere dann, wenn der Einbaubasisrahmen 4 mit dem Einbaugehäuse 4a weitergebildet ist, ist es zwecks der Montage bzw. gegebenenfalls auch der Demontage vorteilhaft, den Einbaubasisrahmen 4 beziehungsweise. das Einbaugehäuse 4a und das gegebenenfalls vorgefertigte Einbauloch nach unten konvergent auszubilden. Der obere Rand des vertikalen Rahmenschenkels 11a befindet sich in der Höhe der Oberfläche 2a. Der horizontale Rahmenschenkel 11b überdeckt die Materialansätze 4d, 4e, wobei er sich vom Scheitel des Aufnahmerahmens 11 nach innen erstreckt.At a distance a above the mounting housing 4a is formed in the circumferential direction continuously formed receiving frame 11 with a substantially vertical frame legs 11a and a substantially horizontally extending frame leg 11b, the horizontal cross-sectional dimension b of sitting on the mounting base frame 4 receiving frame 11 is equal to or greater is as the horizontal cross-sectional dimension of the installation base frame 4 and the installation housing 4a at its upper edge. In particular, if the mounting base frame 4 is further developed with the mounting housing 4a, it is for the purpose of assembly or, where appropriate, the disassembly advantageous, the mounting base frame 4 respectively. the mounting housing 4a and the optionally prefabricated mounting hole down converge form. The upper edge of the vertical frame leg 11a is at the height of the surface 2a. The horizontal frame leg 11b covers the material projections 4d, 4e, extending inwardly from the apex of the receiving frame 11.

Der Aufnahmerahmen 11 dient der Aufnahme eines ringförmige Flansches 12a eines Lampenträger 12, der die Form eines Ringes oder eines topfförmigen Gehäuses 12b aufweisen kann, das eine sich vom Flansch 12a nach unten erstreckende Umfangswand 12c und eine Bodenwand 12d aufweist. Der Flansch 12a ist wenigstens in der horizontalen Richtung und vorzugsweise auch in der vertikalen Richtung bezüglich dem Aufnahmerahmen 11 abgedichtet. Dies kann durch eine Ringdichtung 13 erfolgen, die zwischen der Mantelfläche des Flansches 12a und der Innenfläche des Rahmenschenkels 11a wirksam ist, und/oder durch eine zwischen der Unterseite des Flansches 12a und der Oberfläche des Rahmenschenkels 11b wirksame Ringdichtung erfolgen. Die erstere Ringdichtung kann durch einen zwischen der Umfangs- beziehungsweise. Mantelfläche des Flansches 12a und der Innenfläche des Rahmenschenkels 11b mit radialem Druck wirksamen Dichtring gebildet sein. Auch zwischen der Oberfläche des Rahmenschenkels 11b und der Unterfläche des Flansches 12a kann ein Dichtring angeordnet sein. Der oder die Dichtringe können jeweils eine runde Querschnittsform oder die Querschnittsform eines flachen Streifens, z.B. eine viereckige Querschnittsform haben. Beim Ausführungsbeispiel ist ein winkelförmiger Dichtring 13 mit einem vertikalen Dichtschenkel 13a und einem horizontalen Dichtschenkel 13b angeordnet, wobei der horizontal wirksame Dichtschenkel 13a vorzugsweise eine größere Dicke aufweist als der vertikal wirksame Dichtschenkel 13b.The receiving frame 11 serves to receive an annular flange 12a of a bulb holder 12, which may have the shape of a ring or cup-shaped housing 12b having a peripheral wall 12c extending downwardly from the flange 12a and a bottom wall 12d. The flange 12 a is sealed at least in the horizontal direction and preferably also in the vertical direction with respect to the receiving frame 11. This can be done by a ring seal 13, which is effective between the lateral surface of the flange 12a and the inner surface of the frame leg 11a, and / or effected by an effective between the underside of the flange 12a and the surface of the frame leg 11b ring seal. The former ring seal can by a between the perimeter or. Mantle surface of the flange 12a and the inner surface of the frame leg 11b be formed with radial pressure effective sealing ring. Also between the surface of the frame leg 11b and the lower surface of the flange 12a, a sealing ring may be arranged. The sealing ring (s) may each have a circular cross-sectional shape or the cross-sectional shape of a flat strip, e.g. have a quadrangular cross-sectional shape. In the exemplary embodiment, an angular sealing ring 13 is arranged with a vertical sealing leg 13a and a horizontal sealing leg 13b, wherein the horizontally effective sealing leg 13a preferably has a greater thickness than the vertically effective sealing leg 13b.

Zur Verbindung des Aufnahmerahmens 11 mit dem Einbaubasisrahmen 4 können zwei einander gegenüberliegende oder mehrere auf dem Umfang verteilt angeordnete Verschraubungen mit Schrauben 35 vorgesehen sein. Die Köpfe 35a der Schrauben 35 sind vorzugsweise in den vorhandenen Durchgangslöchern 11c im horizontalen Rahmenschenkel 11b versenkt angeordnet, so dass der Dichtring der Ringdichtung 13 nicht beeinträchtigt wird.To connect the receiving frame 11 with the mounting base frame 4, two opposing or more distributed on the circumference arranged screw with screws 35 may be provided. The heads 35a of the screws 35 are preferably recessed in the existing through holes 11c in the horizontal frame leg 11b, so that the sealing ring of the ring seal 13 is not impaired.

Im z.B. topfförmigen Lampenträger 12 ist eine nach oben gerichtete Lampe 14 gelagert, vorzugsweise auf der Bodenwand 12d. Beim Ausführungsbeispiel ist die Lampe 14 um eine horizontale Schwenkachse 15a eines Schwenkgelenks 15 schwenkbar gelagert. Hierzu kann ein U-förmiger und z.B. mittels wenigstens einer Schraube 15b auf der Bodenwand 12d verschraubter Lagerbügel 16 dienen, in dem ein z.B. ebenfalls durch einen U-förmigen Tragbügel 17 gebildeter Lampenhalter schwenkbar gelagert ist.In eg cup-shaped bulb holder 12, an upwardly directed lamp 14 is mounted, preferably on the bottom wall 12d. In the embodiment, the lamp 14 is pivotally mounted about a horizontal pivot axis 15a of a pivot joint 15. For this purpose, a U-shaped and bolted by means of at least one screw 15b on the bottom wall 12d bearing bracket 16 serve in which a, for example, also formed by a U-shaped mounting bracket 17 lamp holder is pivotally mounted.

Die Unterseite des Lampenträgers 12 eignet sich vorteilhaft dazu, Anschlüss- und Betriebsmittel 19 für die Lampe 14 anzuordnen und zu befestigen. Beim Ausführungsbeispiel sind die Anschluss- und Betriebsmittel 19 durch ein wannenförmiges Gehäuse 21 geschützt angeordnet, das an der Unterseite der Bodenwand 12d befestigt ist, vorzugsweise durch einander gegenüberliegende Schrauben 22 verschraubt ist, von denen aus Vereinfachungsgründen nur eine Schraube 22 dargestellt ist. Die Schrauben 22 durchlassen das wannenförmige Gehäuse 21 von unten nach oben und sind in die Bodenwand 12d eingeschraubt, z.B. in Materialansätzen 12e der Bodenwand 12d. Die Teilungsfuge 23 zwischen der Bodenwand 12d und dem Rand des Gehäuses 21 ist abgedichtet, z.B. mittels einer Ringdichtung 24, die einen Dichtring aufweisen kann, der in einer Ringnut in einer der einander gegenüberliegenden Anlageflächen angeordnet ist.The underside of the lamp holder 12 is advantageously suitable for arranging and fastening terminals and operating means 19 for the lamp 14. In the embodiment, the connection and operating means 19 are arranged protected by a trough-shaped housing 21 which is fixed to the underside of the bottom wall 12d, preferably screwed by opposing screws 22, of which, for simplicity, only one screw 22 is shown. The screws 22 pass the trough-shaped housing 21 from below upwards and are screwed into the bottom wall 12d, e.g. in material approaches 12e of the bottom wall 12d. The parting line 23 between the bottom wall 12d and the edge of the housing 21 is sealed, e.g. by means of a ring seal 24, which may have a sealing ring which is arranged in an annular groove in one of the opposing contact surfaces.

Der Lampen-Aufnahmeraum 25 im Lampenträger 12 ist durch einen flachen Scheibendeckel 26 aus lichtdurchlässigem Material abgedeckt und durch eine zwischen dem Flansch 12a und dem Scheibendeckel 26 wirksame Ringdichtung abgedichtet. Auch an dieser Stelle kann ein zwischen der Oberseite des Flansches 12a und der Unterseite des Scheibendeckels 26 wirksamer Dichtring und ein zur Abdichtung der Mantelfläche des Scheibendeckels 26 vorgesehener Dichtring angeordnet sein. Beim Ausführungsbeispiel kann auch hier ein winkelförmiger oder U-förmiger Dichtring 28 angeordnet sein, der mit einem Schenkel 28a sowohl vertikal zwischen dem Flansch 12a und dem Scheibendeckel 26 als auch mit einem Steg 28b horizontal am Umfang des Scheibendeckels 26 wirksam sein kann.The lamp receiving space 25 in the bulb holder 12 is covered by a flat disc cover 26 made of translucent material and sealed by an effective between the flange 12 a and the disc cover 26 annular seal. Also at this point, an effective between the top of the flange 12a and the underside of the disc cover 26 sealing ring and a provided for sealing the lateral surface of the disc cover 26 sealing ring may be arranged. In the embodiment, an angular or U-shaped sealing ring 28 may be arranged here, which can be effective with a leg 28a both vertically between the flange 12a and the disc cover 26 and with a web 28b horizontally on the circumference of the disc cover 26.

Die Dicke d des Scheibendeckels 26 ist so groß, dass er bei Auflage auf dem Flansch 12a bzw. auf dem Dichtring 28 mit seiner Oberfläche 26a in der Höhe des oberen Randes des Rahmenschenkels 11a und der Oberfläche 2a des Bodens 2 angeordnet ist.The thickness d of the disc cover 26 is so large that it is arranged on the flange 12a or on the sealing ring 28 with its surface 26a at the level of the upper edge of the frame leg 11a and the surface 2a of the bottom 2 when resting.

Da der Scheibendeckel 26 im Aufnahmerahmen 11 versenkt angeordnet ist, kann auf eine besondere Fixiervorrichtung für den Scheibendeckel 26 verzichtet werden. Es ist auch möglich, den Scheibendeckel 26 durch ein zwischen seiner Umfangsfläche und dem Rahmenschenkel 11a oder dem Dichtschenkel 13a wirksame Klemmwirkung in der versenkten Position zu sichern. Die Klemmwirkung kann z.B. durch einen entsprechenden Dichtring hervorgerufen werden, der somit nicht nur die Klemmwirkung, sondern auch die vertikale Abdichtung an der Umfangsfläche des Scheibendeckels 26 besorgt.Since the disc cover 26 is recessed in the receiving frame 11, can be dispensed with a special fixing device for the disc cover 26. It is also possible to secure the disc cover 26 by a clamping effect effective between its peripheral surface and the frame leg 11a or the sealing leg 13a in the retracted position. The clamping effect can be caused for example by a corresponding sealing ring, which thus worried not only the clamping action, but also the vertical seal on the peripheral surface of the disc cover 26.

Beim Ausführungsbeispiel ist ein besonderer Abschlussring 31 vorgesehen, der den Scheibendeckel 26 im Bereich einer vertieften Schulterfläche 26b mit seinem inneren Rand übergreift, mit seinem äußeren Rand die Ringdichtung 13 übergreift und mit seiner Oberfläche 31a in der Höhe der Oberfläche des Scheibendeckels 26 und des Rahmenschenkels 11a angeordnet ist.In the embodiment, a special end ring 31 is provided which engages over the disc cover 26 in the region of a recessed shoulder surface 26b with its inner edge, engages over the annular seal 13 with its outer edge and with its surface 31a at the level of the surface of the disc cover 26 and the frame leg 11a is arranged.

Der Abschlussring 31 kann mit oder ohne einer horizontal wirksamen Klemmwirkung im ihn aufnehmenden Aufnahmeraum zwischen dem vertikalen Rahmenschenkel 11a und der Umfangsfläche des Scheibendeckels 26 angeordnet sein und durch seine Auflage auf den Dichtringen 13, 28 die Abdichtung herbeiführen. Ein solcher Abschlussring 31 weist keine Schraubenlöcher auf.The closing ring 31 can be arranged with or without a horizontally effective clamping action in him receiving space between the vertical frame legs 11a and the peripheral surface of the disc cover 26 and bring about its bearing on the sealing rings 13, 28, the seal. Such a closure ring 31 has no screw holes.

Es ist aber auch vorteilhaft, den Abschlussring 31 in seiner versenkten Position zu verschrauben. Hierzu können zwei einander gegenüberliegende oder mehrere auf dem Umfang verteilt angeordnete längere Schrauben 32, insbesondere Senkkopfschrauben, vorgesehen sein, die den Abschlussring 31 in Löchern 31b, insbesondere Senklöchern, durchfassen, deren Schraubenköpfe 32a im Abschlussring 31 versenkt angeordnet sind, und deren Schraubenschäfte in diesem Fall vorgesehene Löcher 13c im Dichtschenkel 13b sowie die Löcher 11c im Rahmenschenkel 11b durchfassen und in den Materialansätzen 4e in den vorhandenen Schraubenlöchern 8 eingeschraubt sind. Durch eine solche Verschraubung bei der die Schrauben 35 entfallen, wird nicht nur die Sicherung des Abschlussrings 31 in seiner versenkten Position verbessert, sondern es wird auch durch die vertikale Schraubspannung die Abdichtung verbessert und zwar sowohl zwischen dem Abschlussring 31 und dem Dichtring 28 als auch zwischen dem Abschlussring 31 und dem Dichtring 13. Dabei stützt sich der Abschlussring 31 auf dem oberen Schenkel 28c des Dichtringes 28 und gegebenenfalls auch auf der Schulterfläche 26b des Scheibendeckels 26 ab. Den Flansch 12a durchfassen die Schrauben 32 in Löchern 12f.But it is also advantageous to screw the end ring 31 in its retracted position. For this purpose, two opposing or a plurality of distributed over the circumference arranged longer screws 32, in particular countersunk screws, be provided, the 31 penetrate the end ring 31 in holes 31b, in particular countersunk holes whose screw heads 32a are arranged sunk in the end ring 31, and their screw shafts in this Case provided holes 13c in the sealing leg 13b and the holes 11c in the frame legs 11b and pass through are screwed into the material approaches 4e in the existing screw holes 8. By such a screwing in which the screws 35 omitted, not only the securing of the end ring 31 is improved in its retracted position, but it is also improved by the vertical screw the seal and that both between the end ring 31 and the sealing ring 28 and between the end ring 31 and the sealing ring 13. Here, the end ring 31 is supported on the upper leg 28c of the sealing ring 28 and optionally also on the shoulder surface 26b of the disk cover 26 from. The flange 12a is penetrated by the screws 32 in holes 12f.

Es ist auch möglich, den Abschlussring 31 aufzusetzen und nicht zu verschrauben.It is also possible to put on the end ring 31 and not to screw.

Beim Ausführungsbeispiel ist die vertiefte Schulterfläche 26b eine schräge Kegelfläche einer oberseitigen Ausnehmung 26c, die an einem etwa zylindrischen oberseitigen Ansatz 26d des Scheibendeckels 26 endet. Der zugehörige Dichtring 28 weist den aufwärts gerichteten Dichtsteg 28b und den oberen Dichtschenkel 28c auf, der horizontal auf einer horizontalen Fläche der Ausnehmung 26c angeordnet sein kann oder an die Schrägform der Schulterfläche 26b angepasst sein kann.In the exemplary embodiment, the recessed shoulder surface 26b is an oblique conical surface of an upper-side recess 26c, which ends at an approximately cylindrical upper-side projection 26d of the disc cover 26. The associated sealing ring 28 has the upwardly directed sealing web 28b and the upper sealing leg 28c, which can be arranged horizontally on a horizontal surface of the recess 26c or adapted to the oblique shape of the shoulder surface 26b.

Die erfindungsgemäße Ausgestaltung der Einbauleuchte 1 ermöglicht nicht nur eine gute Anordnung der Einbauleuchte 1 im Boden 2, sondern auch eine gute Abdichtung. Dabei wird sowohl die zwischen dem Aufnahmerahmen 11 und dem Flansch 12a vorhandene Fuge als auch die zwischen dem Flansch 12a und dem Scheibendeckel 26 vorhandene Fuge abgedichtet. Außerdem führt die erfindungsgemäße Ausgestaltung zu einer einfachen Konstruktion, deren Bauteile einfach, schnell und kostengünstig herstellbar sind.The inventive design of the recessed luminaire 1 not only allows a good arrangement of the recessed luminaire 1 in the bottom 2, but also a good seal. In this case, both the existing between the receiving frame 11 and the flange 12a gap and the existing between the flange 12a and the disc cover 26 joint is sealed. In addition, the embodiment of the invention leads to a simple construction whose components are simple, quick and inexpensive to produce.

Die Einzelteile der Bodeneinbauleuchte 1 bestehen aus nichtrostendem oder korrosionsfestem Material, z.B. Metall wie Edelstahl oder Kunststoff.The components of the recessed ground luminaire 1 are made of stainless or corrosion resistant material, e.g. Metal like stainless steel or plastic.

Nachfolgend werden Montageschritte eines Montageverfahrens beschrieben, mit denen die Bodeneinbauleuchte montierbar ist.The following describes assembly steps of a mounting method with which the recessed ground light can be mounted.

In ein vorbereitetes Einbauloch 3 wird zunächst der vorzugsweise als Einbaugehäuse 4a ausgebildeter Einbaubasisrahmen 4 eingesetzt und mit dem Boden 2 verankert, z.B. eingegossen, wobei der Einbaubasisrahmen 4 den Abstand a von der Oberfläche 2a des Bodens 2 aufweist.In a prepared installation hole 3, first of all, the installation base frame 4, which is preferably designed as a mounting housing 4a, is inserted and anchored to the floor 2, e.g. cast in, the installation base frame 4 has the distance a from the surface 2a of the bottom 2.

Dann wird der vorzugsweise aus Metall bestehende Aufnahmerahmen 11 aufgeschraubt, dessen oberer Rand mit der Oberfläche 2a bündig ist.Then the preferably made of metal receiving frame 11 is screwed, the upper edge of the surface 2a is flush.

Als nächster Montageschritt wird in den Aufnahmerahmen 11 der Dichtring 13 aus elastischem Dichtungsmaterial eingesetzt, der im Querschnitt ein L-Profil hat.As the next assembly step, the sealing ring 13 made of elastic sealing material is used in the receiving frame 11, which has an L-profile in cross-section.

Als nächstes wird auf den horizontalen Dichtringschenkel 13b der Lampenträger 12 mit seinem Flansch 12a in einer solchen Drehstellung aufgesetzt, dass seine Durchgangslöcher 12f mit den Gewindelöchern 7, 8 fluchten. Dabei liegt der Flansch 12a sowohl mit seiner Unterseite als auch mit seiner Mantelfläche mit einem Dichtungsdruck an den Dichtringschenkeln 13a, 13b an.Next, the bulb holder 12 with its flange 12a is placed on the horizontal sealing ring leg 13b in such a rotational position that its through holes 12f are aligned with the threaded holes 7, 8. In this case, the flange 12a bears against the sealing ring limbs 13a, 13b both with its lower side and with its lateral surface with a sealing pressure.

Dann wird der Scheibendeckel 26 in der passenden Umfangsform, der an seinem Außenrand mit dem Dichtring 28 versehen ist, auf den Lampenträger 12 bzw. den Flansch 12a aufgesetzt, derart, dass die Oberseite des Scheibendeckels 26 mit der Oberfläche 2a bündig ist.Then the disc cover 26 is placed in the matching peripheral shape, which is provided at its outer edge with the sealing ring 28, on the bulb holder 12 and the flange 12a, such that the top of the disc cover 26 with the surface 2a is flush.

Nachfolgend wird der Abschlussring 31 aufgesetzt und vorzugsweise verschraubt, wobei die Dichtringe 13, 28 mit ihren Dichtschenkeln vertikal komprimiert werden, wodurch die Abdichtung zusätzlich verbessert wird.Subsequently, the closing ring 31 is placed and preferably screwed, wherein the sealing rings 13, 28 are compressed vertically with their sealing legs, whereby the seal is additionally improved.

In solchen Einsatzfällen, in denen eine Verschraubung des Abschlussringes 31 nicht erforderlich ist, weil der Abschlussring 31 aufgrund seines Einsetzens und seines Eigengewichtes eine hinreichende Abdichtung herbeiführt, wird nach dem Aufsetzen des Aufnahmerahmens 11 dieser mit den Schrauben 35 verschraubt, wie es in Fig. 1 rechts dargestellt ist. Die übrigen Montageschritte mit einem Abschlussring 31 ohne Löcher für die Schrauben 32 erfolgen dann wie vorgeschrieben.In such applications, in which a screwing of the end ring 31 is not required because the closing ring 31 causes a sufficient seal due to its insertion and its own weight, this is screwed after placing the receiving frame 11 with the screws 35, as shown in Fig. 1 is shown on the right. The remaining assembly steps with a cover ring 31 without holes for the screws 32 then take place as prescribed.

Die Fig. 2, 4 und 6 zeigen Einbauleuchten 1 mit Schrauben 32. Die Fig. 3, 5 und 7 zeigen Einbauleuchten mit nicht sichtbaren Schrauben 35.The Fig. 2, 4 and 6 show recessed lights 1 with screws 32. The Fig. 3, 5 and 7 show recessed luminaires with invisible screws 35.
