Description

The invention relates to the field of electrical lighting of premises

  fitted with false ceilings, especially tertiary or industrial premises. The invention relates more pa rticu l ièrem ent the lighting apparatus and the hanging devices intended to be associated with false ceilings, with a view to the realization of lighting installations. mod u la i res. Generally, two types of switchgear are used for lighting tertiary or industrial premises fitted with false ceilings: - recessed fixtures with direct lighting, fixed to the ceiling or most often supported by the false ceiling, in replacement of a slab of the false ceiling; - suspended devices, necessarily fixed to the ceiling through a

cut in the false ceiling.

  s Here, false ceilings mean any finish covering maintained at a

  certain distance from and obscuring a ceiling.

  For premises for tertiary or industrial use which are frequently built by developers who ignore the details of the interior fittings, which will be defined later by the occupants, the preferred solution with regard to lighting is built-in fixtures with direct lighting. These devices each regularly replace a slab of the false ceiling, depending on the frame of the building, so as to ensure uniform lighting

distributed over the entire surface.

  However, suspended devices, whether they are direct or indirect lighting, have indisputable advantages compared to recessed or evoked devices, this thanks to a very low luminance, guarantee of comfort and ergonomics. However, their positioning in a space equipped with false

  ceilings require supports which are a source of stress.

  In the following description, the terms "lower", "upper >>," vertical ",

  "horizontal" and the like are used with reference to the various elements in the position in which they are found in the figures, that is to say in the position

  OR the hanging device is intended to be fixed to the ceiling.

  We first refer to Figures 1 to 4 which illustrate a first mode of

realization of the invention.

  The attachment device 1 successively comprises, from bottom to top, a base 2, a second plate 3 and a first plate 4 comprising a hole receiving a threaded rod 6 blocked by two nuts 7 (only one being visible

  in the figures, the second being located under the first plate 4).

  s The base 2 includes an element 8, from which protrudes upwards a

  hollow cylindrical sleeve 9, the element 8 and the sleeve 9 being integral.

  A notch 10 is formed on the internal cylindrical face of the sleeve 9,

  The notch 10 being able to open out.

  The notch 10 and the cylindrical cavity delimited by the sleeve 9 form attachment means intended to receive and hold the mast in position.

  cylindrical 11 of a suspended lighting fixture (see Figures 2, 4 and 5).

  So as to provide a space to allow the introduction of the cylindrical mast 11 mentioned, the element 8 has the shape of a crown having in its center an orifice with a diameter greater than the diameter of the mast 11. The crown no 8 and the sleeve 9 are concentric, the sleeve 9 surrounding

The orifice of the element 8.

  The shapes of the mast 11 and of the cavity delimited by the cylindrical sleeve 9 are complementary. The term cylindrical K "is understood here in the broad sense, the mast 11 and the cavity being able for example to present in cross section the shape of an ellipse, a prism, etc. The sleeve 9 comprises a shoulder 12 intended to form, inside the sleeve 9, a stop making it possible to limit the movement of insertion of the lighting apparatus into the base 2. In the embodiment of FIG. 1,

  The shoulder 12 is also formed outside the sleeve 9.

  The second plate 3 is fixed to the base 2 (by any known means such as gluing, or welding), or produced in a single piece with the base 2. The second plate 3 has the shape of a disc whose center is located on the

  same axis as the center of element 8.

  The second plate 3 is substantially parallel to the crown of the element 8 and comprises a central opening 13a as well as recesses 13b in the form of angular sectors, intended to lighten the attachment device 1 without harming its resistance, and to allow the passage of the power cables

  electric for the lighting fixture.

  o Similarly, the first plate 4 is here formed by a disc and is connected to the second plate 3 so that they are substantially parallel, their center being disposed on the same vertical axis also forming the axis

  longitudinal XX 'of the attachment device 1.

  s The connection between the first and second plates 4, 3 is here carried out by three metal rods 5 arranged on the perimeter of a circle whose center is

  located on the longitudinal axis XX 'of the attachment device 1.

  The rods 5 are on the one hand fixed to the first plate 4, for example by screwing, towards their upper end, and on the other hand associated with oblong holes 14 curves made in the second plate 3, towards their lower end. Each rod 5 is mounted so as to pass through an oblong hole 14 and is secured in vertical translation to the second plate 3 by means of a screw or nut 15 mounted at its lower end and bearing on the face

  bottom of second plate 3.

  The radius of curvature of the oblong holes 14 is substantially equal to the radius of the theoretical circle 16 in which the three rods 5 are inscribed, so that a relative rotational movement of the first and second plates 4, 3 is made

  possible. The amplitude of this movement is limited by the length of the holes 14.

  In FIGS. 2 and 4, the attachment device is shown associated with the

mast 11 of a lighting fixture.

  For reasons of clarity, only the mast 11 has been shown. It can receive at its lower end any known lighting device. The mast 11 intended to cooperate with the attachment device 1, according to the first embodiment, is shown in Figure 5 o it appears ^ 't alone. It comprises a substantially cylindrical body provided with two diametrically opposed vertical flats 17 o, as well as two vertical slides 18 arranged on

  the internal face of the cylindrical body, in correspondence with the flats 17.

  The mast 11 also comprises, on its upper part and along one of the

  flats 17, a projecting member 19, such as a retractable pawl.

  Of course, this shape of the mast 11 is only described by way of example, the mast 11 may have other suitable shapes, provided that the shape of the mast 11 allows precise positioning of the first and second means attachment to each other. In particular, the position of the slides relative to the flats may vary, and the existence of flats or

of slides is optional.

  A press button 20, projecting from the outside face of the mast 11, makes it possible to

  force the pawl to retract inside the mast 11.

  The distance between the upper edge of the cylindrical mast 11 and the pawl 19 is chosen to allow engagement of the pawl 19 in the notch 10 during

  the association of the mast 11 with the base 2 of the attachment device 1.

  n / a We now describe the attachment of the hanging device 1 to a support structure comprising a ceiling and a false ceiling, as well as the association of the

  cylindrical mast 11 to said attachment device 1.

  In FIGS. 2 to 4, the attachment device 1 is shown diagrammatically in association with a false ceiling tile 21 (the adjacent tiles have not been shown). The false ceiling is generally substantially horizontal, although this arrangement is not limiting, the hanging device 1 according to the invention can be adapted to a false

  ceiling arranged obliquely to the horizontal.

  The false ceiling slab intended to receive the hanging device 1 comprises an orifice 21 a having a diameter greater than that of the

o sleeve 9.

  The device 1 is suspended by the threaded rod 6 fixed to the ceiling (not shown), for example by screwing. Several threaded rods 6 can

also be planned.

  We will place ourselves here in the case where the ceiling is also substantially horizontal. However, the attachment device 1 can cooperate with a ceiling

  making an angle with the horizontal.

  The sleeve 9 is inserted into the orifice 21a of the false ceiling 21, the second plate 3 being located above the false ceiling and the element 8 below the false ceiling. The length of the threaded rod 6 and its adjustment at the level of the nut 7 are chosen so that the upper face of the element 8 comes into contact with the lower face of the false ceiling tile 21. The false ceiling is thus sandwiched, in a vertical direction, between the element 8 and the

second plate 3.

  The metal rods 5 allow an adjustment of the horizontality of the hanging device 1, while the element 8 forms a cover making it possible to improve the aesthetics of the building and to hide the edges of the orifice 21a of the false

ceiling 21.

  A plurality of hanging devices 1 are thus regularly installed on

  the entire area of false ceilings during the construction of a building.

  Once the devices 1 have been installed in a room, the orifice of each element 8 s provided for the introduction of a lighting appliance mast 11 is visible to the occupants of the room. To remedy this, an additional cache (not

  shown) is intended to hide the opening in question.

  The false ceilings of this type of premises, once completed, have a certain number of tiles 21 provided with an element 8 slightly projecting from their underside. During the fitting out of the premises by the occupants, these determine the distribution of the lighting fixtures to be installed, each false ceiling slab fitted with a hanging device 1 being a potential location for a

lighting fixture.

  At each chosen location, the cover masking the lower orifice of the base 2 is removed and a lighting fixture provided with a mast 11 is inserted therein until the pawl 19 engages in the notch 10, after have provided the connection, by any means complying with standards, between the power supply cables left waiting above the false ceiling and the or

  the power cables of the lighting fixture.

  The press button 20 is disposed on the mast 11 so as to be located below the false ceiling when the mast 11 cooperates with the base. By action on the press button 20, a user can thus release the pawl 19 from the notch 10, after having disconnected the power cables. The hanging of

  the lighting fixture to the hanging device 1 is thus removable.

  The invention thus allows a modular distribution of the lighting points, both during the initial fitting-out of the premises and during possible rearrangements and this does not allow the installation of suspended lighting fixtures.

quickly and easily.

  We now refer to Figures 6 to 9, which illustrate a second mode of

  s realization of the hanging device 1.

  The device 1 comprises, from bottom to top, a base 2, three metal rods 5, a first and only plate 4, and two threaded rods 6

  intended for fixing the first plate 4 to the ceiling.

  The threaded rods 6 are not fixed to the ceiling directly, but via a rail 22, itself fixed to the ceiling (for example via a hanger allowing height adjustment, in particular by threaded rods). This allows better stability, as well as a more flexible adjustment of the position of the base 2 relative to the false ceiling 21 and relative to the orifice 21a of a slab of the false

ceiling 21.

  The base 2 comprises a cylindrical sleeve 9, the diameter of which is less than the diameter of the orifice 21a of the false ceiling 21, so that the sleeve 9 can

  o be inserted into the orifice 21a of the false ceiling 21 (see Figure 9).

  The sleeve 9 comprises a bottom 23, intended to be in contact with the first plate 4. The bottom 23 has a domed portion 24 making it possible to provide a ball-type connection with the first plate 4. The adjustment of the horizontality of the s attachment device 1, via the rods 5, is thus made easier and more precise. The sleeve 9 further comprises an inner skirt 25, substantially cylindrical, projecting from the bottom 23 in the direction opposite to the first plate so 4, intended to accommodate the mat 11. The inner skirt 25 comprises a notch 1 O. possibly opening, intended for cooperate with the

  pawl 19 of the mat 11, removably, the mat 11 comprising a spring 26.

  The inner skirt 25 also comprises means forming a stop, intended to limit the movement of insertion of the lighting apparatus into the base 2, such as

than a shoulder.

  s In addition, the attachment device 1 comprises an element 8, forming a cover, intended to be detachably snapped into the sleeve 9, so that the face on the peri re re dud it element 8 comes substantially into contact with the face lower of the false ceiling 21. The element 8 has the shape of a crown 8a from which protrudes, upwards, a cylindrical extension 8b provided with a

  o external snap bead 8c.

  As before, the element 8 makes it possible to hide the edges of the orifice 21a of the false ceiling 21 to improve the aesthetics of the false ceiling 21

fitted with hanging device 1.

  Finally, reference is made to FIGS. 10 and 11 which illustrate a third mode of

realization of the invention.

  In FIG. 10, only the base 2 and the false ceiling 21 have been shown,

  but not the means for fixing the base 2 to the ceiling.

  The base 2 comprises for example a sleeve 9 similar to that of FIGS. 6 to 9. However, the base 2 could have different characteristics, this third embodiment differing from the other modes essentially by s the reciprocal hooking means of the lighting fixture and the device

hanging 1.

  The mast 11 here comprises two pins 27, substantially perpendicular to the axis of said mast 11. The base 2 comprises, for its part, a part 28 in the form of a hollow half cylinder, having two notches 29, symmetrical, intended for

  cooperate with the pins 27 of the mast 11 of the lighting apparatus.

14 2836207

  According to one possible embodiment, it is not the mast 11 which carries the lugs 27, but an additional part 30, with which the mast 11 can be associated, for example

example by screwing (figure 11).

  s The attachment of the mast 11 of the lighting apparatus to the attachment device 1 is done in the manner of a bayonet system, by the succession of three displacements illustrated by the arrow F in FIG. 11: a displacement upwards, then a horizontal movement followed by a downward movement, so as to engage the pins 27 in the notches 29 of the part 28 linked to

o base 2.

  The part 30, or the mast 11, further comprises an orifice 31 intended for the passage

  cables 32 supplying the lighting apparatus.

  s Of course, it is understood that, from the three embodiments described, it is possible to produce a different attachment device 1, having

  characteristics belonging to each of these three modes.
