Description

The invention relates to a holder for a recessed ceiling light according to the preamble of claim 1.

Recessed ceiling lights of the type in question work with different illuminants. In the context of the present invention, compact fluorescent lamps are described for the sake of simplicity, but the invention is not restricted to the use of such compact fluorescent lamps.

Such lamps are anchored with their longitudinal axis transversely to the light exit plane as a rule in the side surfaces of a basic housing of the recessed ceiling light in associated sockets.

When using such lamps in connection with an associated socket, there is a need to anchor this lamp with socket in a particularly simple and cost-saving manner on the basic housing.

It is known here to provide a so-called frame carrier, to which the frame is fastened with the aid of a screw fastening, the frame carrier itself being fastened to the basic housing with the aid of a riveted connection. Such a fastening has the disadvantage that it is relatively complex, because, as a rule, the lampholder carrier must be at least partially loosened when the recessed ceiling light is installed, so that it can be pivoted into the ceiling opening together with the basic housing. The usage of Screwed connections between the socket and the socket holder require a tool for assembling the socket and the use of a rivet connection between the socket holder and the base housing prevents such a socket holder from being movably attached to the base housing. This creates the aforementioned difficulties when installing the recessed ceiling light in an assigned installation opening.

The invention is therefore based on the object of developing a lampholder for a recessed ceiling light of the type mentioned in such a way that simple, reliable and preferably movable fastening to the basic housing is ensured at lower production costs.

To achieve the object, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that there are one or more connections that can be released without tools between the mount carrier and the basic housing, which connections are designed as snap or snap connections in a preferred embodiment.

This has the major advantage that on the one hand the holder is movably but nonetheless locked to the basic housing, so that it can be pivoted upwards when mounting the recessed ceiling light into an assigned installation opening in the ceiling, so that it can be guided through the recessed opening in a favorable way even under difficult installation conditions to be able to. Another advantage is that because of the detachable connection between the frame carrier and the base housing can now be used with different frame supports. Socket carriers can thus be used, any sockets being able to be fastened in the frame carrier and the frame carrier having different installation positions.

It is preferred here if the connection between the associated socket and the socket carrier is also designed as a tool-free detachable connection, in particular as a snap or snap connection.

This has the advantage that a single frame holder can be used for a different number of frames and different frames can be easily attached to this frame holder.

This means that different lamps can be used with the recessed ceiling light in a simple manner.

The aforementioned snap or snap connection between the holder and the base housing of the recessed ceiling light is preferably designed as a pivotable snap or snap connection. This has the advantage that mounting hooks are arranged in the area of an upper plate on the basic housing, onto which associated snap hooks of the mounting bracket can be snapped, whereby the mounting bracket can be pivoted in this type of mounting around the mounting hooks into a vertical mounting position and into a horizontal mounting position.

The terms "vertical mounting position" and "horizontal mounting position" do not mean that it must necessarily be a swivel angle of 90 °. Smaller swivel angles can also be provided.

In another embodiment, it is provided that no swivel path is provided at all, i.e. In this version, the lampholder is detachably but not pivotally connected to the basic housing, whereby to install the recessed ceiling luminaire with the lampholder attached to it, the recessed ceiling luminaire is inserted into the recessed ceiling opening at a slight angle to the longitudinal axis, after which it can be pivoted back into the vertical mounting position.

With the detachable, tool-free connection between the socket carrier and the basic housing, the main advantage is that parts can already be pre-assembled at the site. It is envisaged that the lamp with its socket and the associated ballast can already be anchored in the socket holder without tools and that the ballast is already connected to the power supply at the installation site. This has the advantage that the lamp hangs down with its socket and the associated holder on the construction site through the ceiling opening and already provides light on the construction site.

If the ceiling recessed luminaire is then to be finally installed after completion of the corresponding construction surfaces, then only the lamp is removed from the socket in the holder and the frame carrier is attached to the basic housing using the snap or snap connection mentioned. The basic housing with the mount carrier mounted thereon is then guided through the ceiling installation opening and fixed to the circumferential edge of the ceiling installation opening with the aid of springs which engage in the corresponding slots on the lateral struts of the basic housing.

Then the reflector is detachably attached to the basic housing with the help of a locking knob and then the lamp is inserted and fastened again in the socket on the holder. This means that the recessed ceiling light is installed simply and reliably.
One or more recesses are provided on the reflector for introducing the illuminants into the interior of the reflector.

The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another. All of the information and features disclosed in the documents - including the summary -, in particular the spatial design shown in the drawings, are claimed to be essential to the invention, insofar as they are new to the prior art, individually or in combination.

In the following, the invention will be explained in more detail with the aid of drawings showing only one embodiment. Here, from the drawings and their description, further features and advantages of the invention that are essential to the invention emerge.

The basic housing 1 according to FIG. 1 essentially consists of a circumferential ring 2, on which an annular flange 3 is preferably formed in one piece from a material. Struts 4, which are uniformly distributed on the circumference, are preferably formed on the ring flange 3 and are angled obliquely upwards and converge in the area of a plate 5. The struts 4, the plate 5 and the ring flange 3 and the ring 2 are preferably made of a one-piece part and preferably consist of a plastic material.

For ease of manufacture 5 recesses 6 are provided in the area of the plate to weight and Save material.

In the struts 4 vertical slots 7 are embedded, on the back of which locking surfaces 8 are arranged. Through the slots 7 reach metal angles, not shown, which engage in a latching manner on the latching surfaces 8 on the one hand and protrude forward on the slot 7 with corresponding spring tabs, so as to support the spring tabs on the circumferential edge of a ceiling installation opening, not shown.

It is important that fastening hooks 9 (preferably 2 pieces) are arranged laterally in the area of the plate, which form the latching bearing (pivot bearing) for the mount carrier 15 to be described in FIG.

The mount carrier 15 is namely held on the one hand pivotably and latching on the fastening hook 9 and on the other hand lies against the edge 10 of the ring flange 3 and is supported by it.

At the edge 10 centering ribs 11 are arranged, which ensure the central anchoring on the peripheral edge 10 of the ring flange 3 when the frame carrier 15 is pivoted into its basic position.

In the basic housing 1, moreover, a reflector 12 is fastened releasably, a locking toggle 14 reaching through a corresponding fastening recess 13 in the reflector roof and being releasably locked in the region of a plate 5 in the region of a fastening recess, not shown. It is a type of bayonet snap-in connection.

A recess 44 is provided in the reflector 12, through which the illuminants are inserted into the interior of the reflector.

According to Figure 3, the frame carrier 15 consists of an approximately U-shaped base body 16, which preferably consists of a plastic injection molded part. The roof of the base body 16 has recesses 17 and 15 snap hooks 19 are also arranged on the top of the frame carrier, which cooperate with the aforementioned fastening hooks 9 on the base housing 1.

On the bottom side of the base body 16 of the frame support 15, latching brackets 18 are arranged, which cooperate with the associated centering ribs 11 on the peripheral edge 10 of the base body 1.

A locking bracket 24 serves as strain relief for a cable 23 which connects the socket 21 to a ballast 22.

As already mentioned at the beginning, the ballast 22 is first connected to the existing power supply at the place of assembly, the lamp 20 being supplied with current via the cable 23 and the socket 21. It can therefore be used as a lamp on the construction site. At the same time, the cable 23 is fastened to the holder support 15 in a strain-relieved manner via the locking bracket 24 mentioned. The socket 21 is releasably latched onto the socket carrier 15 by means of the snap connection shown in more detail in FIG.

According to FIG. 5, the mount carrier 15 essentially consists of a curved edge 25, which lies as close as possible to the curved outer contour of the reflector 12.

If the reflector 12 is not exactly mounted in the basic housing, then it is ensured with the peripheral edge 25 that no light emission takes place between the reflector 2 and the mount carrier 15.

The lower locking bracket 18 consists essentially of a front tab 26, which is followed by a recess 27, behind which a further tab 28 is arranged.

The upper snap hooks 19 are provided with snap arms which can be moved resiliently relative to one another and have a central bracket 32 which cooperates with an axis 33 on the fastening hook 9.

Plate elements 29 are arranged in the area of the upper surface of the frame carrier 15, between which the aforementioned recesses 17 are provided, with vertical plate elements 30 engaging in the recesses 17.

According to FIG. 6, the vertical plate elements 30 form lateral lugs 35a, 35b on their underside, which each form grooves 34 between them in pairs.

The socket 21 has a front locking tab 37, the upper, free end of which is approximately barb-like. It engages in the locked state via an assigned lateral extension 35a in the area of the frame carrier 15.

Adjacent, but behind the latching lug 37 there is a hook element 36 which has a rear, has an approximately L-shaped bent lip 38, on the underside of which a support rib 39 is arranged. As can be seen in Figure 7, the socket 21 is pivoted in the direction of arrow 42 coming from below against the groove 34 in the socket carrier 15, so that in the pivoted state the lip 38 with the support rib 39 rests on the rear side extension 35b. Upon further pivoting in the direction of arrow 42, the barb-like nose of the latching lug 37 then snaps over the front lateral extension 35a, so that a latching connection between the socket 21 and the socket carrier 15 is thus created.

As can be seen from FIGS. 5 and 6, the holder 15 preferably has a plurality of plate elements 30 to which the holder 21 can be fastened, as a result of which different installation positions for the holder 21 of the illuminant are possible in the holder 15. One or more sockets 21 can accordingly be fastened in different positions in the frame carrier 15.

As soon as the two parts are locked together, the socket support 15 can be locked to the basic housing 1.

It is provided that when the frame carrier 15 is pivoted approximately vertically in the direction of arrow 40, the entire frame carrier 15 is guided in the direction of arrow 43 with its snap hooks 19 against the fastening hooks 9 of the basic housing 1 pointing in the direction of arrow 43.

Here, the resilient arms of the snap hooks 19 snap onto the respectively assigned axes 33 of the fastening hooks 9, so that the axes 33 can be gripped around.

The bracket 32 arranged on the snap hook 19 in the middle region acts here as a stop and as a suspension limitation for the resilient arms of the snap hook 19.

The entire mount carrier 15 can then be pivoted downward in the direction of arrow 41 into the basic position shown in FIG. 6, the lower catch bracket 18 then being connected to the peripheral edge 10 of the basic housing 1. It is provided here that the front tab 26 bears against the inside of the rim 10, the recess 27 snapping over the rim 10 and, as the rear limit stop of the tab 28, bears against the outer circumference of the ring flange 3.

The socket 21 and the lamp, not shown, are pivoted through the recess 44 at least partially into the interior of the reflector 12.

The aforementioned centering ribs 11, which are connected to the edge 10 of the base body 1, serve to center the frame carrier 15 when the pivoting movement is carried out in the direction of arrow 41.

With the fastening described, the main advantage is achieved that the holder 15 can be locked without tools with the base housing and there is the further advantage that the holder 21 can be locked without tools with the holder 15.

The locking connections described can also be replaced by other known locking connections. Instead of arranging the fastening hooks 9 on the base housing 1 and the opposing snap hooks 19 on the mount carrier 15, the reverse embodiment can also be chosen, namely that the fastening hooks 9 on the mount carrier and vice versa the snap hooks 19 are arranged on the base housing.

Furthermore, it is possible to design the lower latching bracket 18 of the socket support 15 with the basic housing 1 differently, in that resiliently interlocking latching means are also provided in this area.
