Description

The invention relates to a ceiling lamp capping, and in particular a capping device with a branch for a lamp of the ceiling spot type, in particular of the industrial ceiling spot type. This capping device is able to be mounted in a ceiling.

The invention relates to a kit for forming a capping device, a method for mounting a capping device, and a capping device.

For small lamps, around 5 to 10 cm in diameter, lamp capping devices are known, comprising branches separated from each other in order in particular to thermally insulate the lamp with a layer of insulation material of the strip or sheet type disposed in the plenum or thickness of the ceiling. The separation of the branches in particular facilitates installation and the dispersion of the heat emitted by the lamp.

There exists a need for a capping device allowing more compact storage and/or transport.

The documents DE 103 35 515 and EP 0 427 498 describe devices with metal branches held together by a pivot connection. A ceiling lamp capping device is proposed, this device comprising a plurality of branches for capping the lamp, in which the capping device comprises means for fixing at least one of the branches (referred to as the fixable branch) in said plurality of branches at least one other branch in the plurality of branches of the capping device.

According to the invention, the fixing means are arranged for fixing by clipping on.

The fixable branch may advantageously be conformed so as to rest on a bottom ceiling layer when the assembled device is installed on this bottom layer. "Installed" means disposed so as to cap a lamp, in accordance with normal conditions of use.

For example, the fixable branch may extend between a first end cooperating with at least part of the (and/or integrating at least part of the) fixing means, referred to as the fixing end, and a second end referred to as the support end.

The fixing of the fixable branch or branches to at least one other branch may be direct, namely the fixable branch is then clipped directly onto one or more other branches, or not. In the case of indirect fixing, it is possible for example to provide a support piece on which the fixable branch or branches is/are clipped.

Thus the capping device is not formed in a single piece. It is possible to mount this device by fixing one or more branches. This may allow more compact storage than in the prior art in which the capping devices are at best stacked one on the other.

Before mounting, the capping device may be stored, transported, marketed, etc. in kit form.

The fixing means may allow removable or non-removable fixing. Removable fixing means allow removal of the branch or branches of the capping device as well as reinstallation. On the other hand, when the device comprises non-removable fixing means, the branch remains in place once installed on the capping device.

The fixing means may allow adjustable fixing or not. Adjustable fixing means make it possible to move the branch with respect to the rest of the capping device. It is thus possible to adapt the dimensions of the capping device to the dimensions of the lamp and the thickness of the ceiling.

Clipping on makes it possible to reconcile ease of construction of the capping device and strength of the constructed device. In particular, this clip-on operation may occur when the capping device is installed in the ceiling system, rather than in the factory. The various parts of the capping device can be transported and sold in kit form.

The fixing means, for example the clip-on means, may for example comprise one or more recesses defined in the capping device and a clip-on lug forming a protuberance with respect to the rest of the branch of the capping device, this clip-on lug being conformed so as to be inserted snapped in this recess.

Advantageously, the fixing means may further comprise a locking lug able to be inserted in another recess in the capping device.

The fixing means may be mounted on or defined by this at least one branch and/or by the rest of the capping device.

Advantageously, the capping device may comprise, apart from the plurality of branches, one (or more) support element, this element being arranged so as to cooperate with at least one branch. Thus it is possible to fix one or more branches of the capping device to this support element, which can advantageously have a form adapted to support an insulating fibre sheet.

The invention is in no way limited to the presence of a support element. It is possible for example to provide a capping device, the branches of which have ends arranged to cooperate with one another, so as to allow fixing of one or more of the branches to the rest of the device.

Advantageously and non-limitatively, for at least one fixable branch, the fixing means are arranged so as to define a plurality of fixing positions of this at least one branch. This may thus allow adaptation of the dimensions of the capping device to the dimensions of the lamp for which this device is intended.

For example, it is the fixable branch that can define a plurality of engagement means at the same location of the support element, for example a series of clip-on lugs able to be inserted in a recess in the support element.

According to another example, for at least one branch that can be fixed to the support element, the support element is arranged so as to define a plurality of fixing positions of this at least one respective branch. Thus it is possible to dispose the fixable branch or branches to a plurality of locations of the support element.

For each fixable branch, the support element may define a set of at least one fixing position and, for at least one of these fixable branches, the corresponding fixing set may comprise a plurality of positions. For example, the support element may define a single position for one of the branches, and a plurality of positions for the other one of the branches.

Advantageously and non-limitatively, for at least one fixable branch, the position set corresponding to this branch extends on a substantially radial axis. Thus it is possible to dispose the branches so as to form a more or less narrow capping device.

For example, the support element may comprise parts extending longitudinally from a centre, each part corresponding to a branch, and each part defining a set of positions for this branch along this part.

In another embodiment, the support element may have an H shape, the parallel segments of this H defining a set of positions for two respective pairs of branches.

Advantageously and non-limitatively, the support element and/or the fixable branch or branches may comprise a marking of the various defined positions. This can enable the users to easily find the position corresponding to a given type of lamp.

The capping device may be mounted, for example embedded, in a false-ceiling system of the slab or tile type, and/or frameworks (suspended or fixed by another means), but the invention is not limited to an application to false-ceiling systems. Provision could for example be made for mounting the capping device in a conventional ceiling, for example with beams, in the thickness of the ceiling. The sealing comprises a bottom layer, for example a set of slabs resting on a support framework or gypsum board, this bottom layer being disposed so as to form an internal space able to receive insulating material in the form of a sheet, and/or the like.

The invention is moreover in no way limited by the type of false ceiling in which the capping device may be installed.

The invention may in particular find applications in ceilings and false ceilings of factories, offices, dwellings, common parts of buildings, or the like.

The lamp is mounted, for example embedded or not, in the ceiling.

The capping device may be mounted embedded in the ceiling by pressing it in (from underneath upwards), after assembly, in an orifice in the bottom layer of the ceiling corresponding to a lamp location. The capping device may alternatively be placed from above on the bottom layer of the ceiling. In the first case, it may be advantageous to provide, at the ends of the branches, external tabs intended to come to be pressed into the thickness of the edge of the orifice of the bottom layer of the ceiling.

The capping device may optionally be mounted on a plate suitable for supporting the capped lamp and for resting on a ceiling system so as to transmit its own load and the load of the lamp to a bearing structure of the ceiling system. Such a plate is described in the patent application FR 1156161. In this case, the external tabs are detached and the branches simply come to rest in abutment against the edge of the orifice in the plate corresponding to the location of the lamp. A ceiling is also proposed comprising at least one lamp-capping device as described above.

This ceiling may for example comprise a false-ceiling system with conventional false-ceiling elements, such as for example a framework, for example with longitudinal members, false-ceiling slabs or sheets, elements for suspending the framework, embeddable lamps, and/or the like. A kit is also proposed, intended to form, after assembly, a capping device for a ceiling lamp, this kit comprising at least one branch for capping the lamp, and defining means for clipping this at least one branch onto at least one other branch in the plurality of branches of the capping device. When the capping device is mounted and installed on a bottom ceiling layer, the branches rest on this bottom layer.

Advantageously and non-limitatively, the kit may further comprise at least one support element able to be secured to this at least one branch.

Advantageously and non-limitatively, the kit may comprise a first set of at least one branch of a first type and a second set of at least one branch of a second type. The branches of the first type have a form different from that of the branches of the second type.

For example, the branches of the first set may have a first length, and the branches of the second set may have a second length greater than the first length. Such a kit thus makes it possible to obtain capping devices having a first height or a second height.

This allows even better adaptation to the dimensions of the lamp.

Of course it is possible to provide more than two lengths of branch, for example three, four or even more lengths of branch. Alternatively, it is also possible to provide only one length of branch.

According to another example, the branches of the first and second type may be of different designs. "Of different designs" means that the form of the branches of the second type is not obtained by homothetic transformation from the form of the branches of the first type. For example, the branches of the first type may be designed so as to extend in an oblique direction with respect to the vertical when the resulting capping device is installed in a horizontal ceiling, while the branches of the second type may be designed so as to extend in the vertical direction when the capping device obtained with these branches of the second type is installed in a horizontal ceiling. According to another example, these two types of branch are designed so as to extend in two different oblique directions after installation.

Advantageously and non-limitatively, the kit may further comprise at least one support element of a first type and at least one support element of a second type, the support element of the first type having a form different from that of the support element of the second type.

For example, the support element of the second type has dimensions greater than those of the support element of the second type.

Advantageously and non-limitatively, the support elements of the first and second type are of different designs. "Different designs" means that the form of the support element of the second type is not obtained by homothetic transformation from the form of the support element of the first type. For example, the support element of the first type may have a star shape with parts extending from its centre, while the support element of a second type may have an H shape. The support element of the first type is then particularly suited to lamps having a relatively centred cross section, for example round or square lamps, while the support element of the second type may be suited to bulky lamps or ones extending in a longitudinal direction, for example lamps with a roughly rectangular or elliptical shape. A method for mounting a lamp-capping device for a ceiling is also proposed, comprising a step of fixing, for example by clipping on, at least one branch conformed so as to at least partially cap the lamp on the rest of the capping device. This branch has an end resting on the bottom ceiling layer when the capping device is installed on this bottom layer.

The branches of the capping device may form an assembly forming a capping structure and/or defining a capping envelope for protecting the lamp from a layer of insulating material and sprayed material, for example in the form of flakes.

The invention may find a particularly advantageous application in the capping of relatively large lamps, for example 10 to 40 centimetres in diameter, but it is in no way limited to this type of lamp.

In the present application the terms "high", "low", "above", "below", "vertical", "horizontal", etc. are to be taken in the common meaning (that is to say the gravity vector is in the vertical direction, from top to bottom), for a capping device installed in accordance with normal conditions of use, on a horizontal ceiling layer. However, naturally, the capping device is capable of being oriented differently, in particular before installation thereof in the ceiling system.

The invention will be understood better with reference to the accompanying figures given by way of examples, in which: - figure 1 is a perspective view of an example of a lamp-capping device according to one embodiment of the invention, - figure 2 shows an example of a support element for a capping device according to one embodiment of the invention, - figure 3 shows two examples of branches for a capping device according to one embodiment of the invention, - figure 4 shows an example of a capping device according to one embodiment of the invention.

Identical references may designate elements identical or similar from one figure to another.

With reference to figure 1, the capping device 1 comprises three branches 2 and a support element 3.

The support element defines recesses 6 forming means for fixing to the branches 2.

The branches 2 also comprise means for fixing to the support element 3, here a locking lug 4 and a clip-on lug 5 able to be inserted in two adjacent recesses 6 of the support element 3.

In this embodiment, the locking lugs 4 comprise a small rib (scarcely visible in figure 1) intended to be partly received in a groove 15 of a recess 6. This small rib reinforces the lug 4 mechanically.

To mount a branch 2 on the rest of the capping device 1, the branch 2 is inclined so as to be able to slide the clip-on lug 5 into a recess 6 of the support element 3, and then, once the lug 5 is inserted in this recess 6, the branch 2 is tilted so as to introduce the locking lug 4 into an adjacent recess, thus clipping the branch 2 onto the rest of the capping device 1.

Thus this capping device can be transported and/or stored in the dismantled state, and then assembled prior to or during the installation in the ceiling, for example a false-ceiling system.

With reference to figure 2, the support element 3, with a roughly star shape, comprises three support parts or branches 7 for supporting a layer of insulating material. Each support branch 7 defines a set of locations 6 for a respective capping branch 2.

Each support branch 7 thus comprises seven recesses 6, each pair of two adjacent recesses constituting a location for a capping branch 2.

The support element 3 further comprises a marking 8 for enabling the person installing the capping device to easily choose the locations in which to embed the branches according to the dimensions of the lamp to be capped. The clip-on lugs 5 are marked with an arrow 14 (figure 1) in order to indicate to the user the mark to be taken into account.

The support element 3 further comprises holding tabs 13 for holding the electrical supply wires of the capped lamp.

With reference to figure 3, a branch of a first type 2a and a branch of a second type 2b are shown. The branch 2a has a much shorter length than that of the branch 2b. For example, the branch 2a has a height Ha of 150 millimetres, while the branch 2b has a height Hb of 240 millimetres.

On the other hand, these branches are arranged with fixing means 4a, 4b, 5a, 5b with the same dimensions from one branch to another. These fixing means 4a, 4b, 5a, 5b are intended to be embedded in two respective recesses 6 of the support element 3, and are disposed at one of the ends of the respective branch 2a, 2b, referred to as the fixing end.

The lugs 4a, 4b comprise small reinforcing ribs 16a, 16b, intended to be partly received in a groove 15 in a support element.

When the capping device is installed in the ceiling, each branch 2a or 2b comes to bear by its end opposite to the fixing end, referred to as the support end, on the bottom ceiling layer, and more precisely on the rim of the orifice in the bottom ceiling layer, the plates 10a, 10b coming into abutment against the bottom ceiling layer.

The branch 2a or 2b also comprises an external tab 9a, 9b intended to come to be pressed into the thickness of the rim of the orifice in the bottom ceiling layer in which the capping device is intended to be installed. This external tab 9a, 9b thus makes it possible to stabilise the installation.

The user may wish to dispose a support plate resting on a bearing structure of the ceiling, in order to avoid making fragile elements of the bottom ceiling layer, such as for example a false-ceiling slab, carry the weight of the lamp and of the capping device. The branches 2a, 2b are conformed with rupture points (not visible in figure 3) for easily separating the tabs 9a, 9b from the rest of the branches. These tabs 9a, 9b are thus breakable. Before disposing the capping device on the support plate, the user withdraws the tabs 9a, 9b. Once installed, the capping device comes to rest in abutment against the rim of an orifice in the support plate, the plates 10a, 12a, 10b, 12b coming into abutment against this rim. The branches 2a, 2b extending longitudinally in an oblique direction with respect to the support plate, the weight supported by the capping device wedges these branches 2a, 2b against the rim of the orifice in the support plate.

The branches 2a, 2b further comprise ribs 11 (figure 1), 11a, lib. These ribs stiffen the branches. The branches can thus combine lightness and compressive strength.

Thus it is possible to act on the length of the branches by choosing branches of the same type as the branch 2a or of the same type as the branch 2b, and it is also possible to act on the positioning of the branches by choosing one from the six locations defined on the support element 3.

The following table gives the lamp diameter suitable according to the mark chosen from the six marks 8 of the support element 3, and according to the type of branch chosen from the branches 2a, 2b.

Figure 4 shows another example of a capping device 21. This capping device comprises the branches 2 with the same design as those of figures 1 and 3, and another type of support element 23.

The support element 23 has a different design from the star-shaped support element 3 in the previous figures.

The support element 23 thus has a general H shape, the two parallel branches of the H defining a set of locations for the two respective pairs of branches 2. The bar at the middle of the H is relatively extensive, which thus makes it possible to cap lamps with larger dimensions or lamps extending in a longitudinal direction. It is also possible to make provision for disposing a plurality of capping devices 21 with support elements with an H shape side by side, so as to form a capping cage with an envelope in the form of a tunnel, in order to cap lamps of the tube type for example, in particular neons.

The invention is not limited to the examples of support elements given here by way of example. The support element could alternatively have a square shape (for example a square plate with or without recesses), rectangular, hexagonal or other shape). A kit comprising branches 2a, 2b and support elements 3, 23 can thus make it possible to produce a wide range of capping devices. It is in fact possible to adapt to the dimensions of the lamp and/or to the height of the thickness of the ceiling but acting in particular on the type of branch, the type of support element and the location for fixing the branches to the support elements.

This kit can be sold commercially, with only one of the types of branch and/or support element, or a plurality of types of branch and/or support element.
