Description

The The present invention relates generally to the technical field of Lighting equipment and especially those embedded in the ground Lighting Equipment especially on pavements, squares, Halls, etc. for the purpose of lighting public or private places mainly in the Outdoor, but also inside buildings. More particularly, this invention relates to a holding device and a device for adjusting the orientation of a reflector and the associated Lamp for Such embedded in the ground lighting fixture.

One lighting fixture incorporated into the floor comprises, as generally is known, a sunken in the tub, the optics Contains lamp and reflector, the whole covered with a closing glass is flush with the ground concludes. The optics, which is altogether oriented so that they are upwards is either a fixed optics or one in the Alignment adjustable optics. As for the adjustment of the orientation On the other hand, you can only refer to the inclination adjustable optics and the inclination and rotation to distinguish a vertical axis simultaneously adjustable optics. These types of adjustment allow it on request, the light beam, which emanates from a recessed into the ground lighting fixture, not to lead vertically but diagonally and thus for example on a wall or a pillar or another part of a building to create a specific lighting effect, which is adapted to a special purpose. The present The invention relates to a holding device and a device for Alignment of the reflector both in terms of inclination as well as the Rotation about a vertical axis.

in the In general, the fixtures and fixtures have to Adjusting the orientation of the reflector for recessed into the ground lighting a very simple design and allow only an adjustment of the Tilt of the optics. Sitting in a typical known construction the reflector is elastic on a support in the form of a simple Lyrabügels, on the floor of the lighting device or on its side wall is attached.

As an example of such known devices, reference is made to the patents US 5,908,236 and US Pat. No. 6,502,967 , The patent US 5,887,966 , which is the closest prior art, describes a holding device and a device for adjusting the orientation of the reflector for a recessed lighting fixture according to the preamble of the self-contained claim.

The Main problem that arises with the current simple devices to adjust the alignment, is that they are the Inclination of the reflector, which at the initial start of the Lighting fixture, especially for the "lighting" of a building is set, do not "save." This reflector tilt is then lost and is adjusted at the first maintenance work, which is done on the lighting device, for example when replacing a light bulb the lamp.

at Certain existing devices may have the tendency of a reflector simply be locked by a screw and a nut. These devices but are still not very practical in operation, because it is at you need remove the reflector from the lighting device to the screw / nut system located under the reflector tighten. About that In addition, the given in this case handling brings a twofold Risk of misalignment, on the one hand, if the reflector is removed, and on the other hand, if the screw / nut system is tightened.

The The present invention has the object of all those described above Eliminate disadvantages by having an improved device provides for holding and adjusting the orientation of the reflector, which ensures that the reflector and the associated lamp one in the ground taken in lighting fixture given angular positions immovable and set according to the adjustment be at the same time adjusting the orientation in several Directions can be done by a very simple handling and no risk of adjustment during maintenance work or during Change of light bulbs consists.

For this purpose, the subject of the invention is a device for holding and adjusting the orientation of a reflector for a ground recessed lighting fixture by which the reflector with the associated lamp in terms of inclination and rotation is adjustable about a vertical axis, said device in essential characterized in that the reflector is fixedly connected to a first carrier in the form of a Lyrabügels, the two arms pointing upwards and which are mounted at their upper ends respectively by lateral pivot pins defining a horizontal axis of rotation, movable between the corresponding upper Ends of the two upwardly facing arms of a second carrier in the form of a lyre bar rotatably mounted about a central pivot defining a vertical axis of rotation on a horizontal platen located below the reflector is arranged and which is provided with a series of holes which lie at regular intervals on a circle which is centered on the aforementioned vertical axis, while a flexible angled rod which is fixedly connected to the second support bracket and in a vertical plane perpendicular to the plane of this second support bracket, having a first substantially horizontal part, which is provided with a fixing pin which is directed downwards and serves to cooperate with one of the holes of the horizontal support plate, and has a second part, the extends the first part and which is directed upward and is provided in its upper portion with a series of rectilinear holes, which are spaced apart at regular intervals and are provided to cooperate with a fixing pin which sits on a flexible adjusting rod, the at the periphery of the reflector opposite the b flexible angled rod is attached.

Preferably are the two lateral pivots and the central pivot, ensure the rotation of the two Lyra-shaped support bracket, elastic pivot, especially with an elastic disc.

Of the upper portion of the second part of the flexible angled rod, in which the series of rectilinear aligned holes is arranged is advantageous a circle bent in a circle shaped on the aforesaid horizontal The axis of rotation is centered, with the holes in this bent area are arranged at regular angular intervals and the tips of the respective angles on the aforementioned horizontal Rotary axis lie.

at a preferred embodiment The flexible angled bar and setting bar are made very much flexible flat bands, in particular metal bands.

The Device with double lyre-shaped support straps, the The subject of the invention is therefore allows the alignment the reflector, and consequently the lamp of a lighting fixture embedded in the floor, on the one hand in terms of inclination, by the choice of the hole in which the the adjusting rod attached fixing pin is inserted, and on the other hand in terms of rotation about the vertical axis by the choice of Holes in the row of holes, which are arranged in a circle on the horizontal plate, in the the attached on the flexible angled rod fixing pin inserted becomes. In this way it is possible the inclination of the reflector, for example, over an angular range of 30 ° and to set its position in the rotation about the vertical axis through 360 °, not infinitely, but nevertheless, according to the intervals between the Adjusting holes, in relatively small angle "steps" for that particular Use, For example, in steps of the order of 2 ° to 6 ° (depending on Strength the fixing pins).

These Device guaranteed also through Actuate a single operating part, namely the free end of the Adjusting rod, which forms a kind of operating lever or handle, without screwing or unscrewing the angle adjustment and the Locking (after adjustment) of the reflector, therefore also the light bulb, both in terms of inclination as well as the rotation about the vertical Axis.

Furthermore are the operations the adjustment and fixation with respect to the two directions (inclination and rotation) is easy to carry out, wherein the reflector remains in the illumination device, ie without the need for him for each Setting to take out what the speed and accuracy the setting considerably elevated. It is even possible to let the lamp light up during the adjustment process to immediately start the desired Orientation to find what interesting in the case of metal iodide lamps is that with each turn on warm-up times in the order of magnitude of ten minutes and they do not, once they're out re-energized before the end of about twenty minutes be allowed to.

Finally is it by the force exerted by the lateral and central pivot braking action and through the interaction of the two pins and the corresponding holes ensured accurate Positioning particularly light, the reflector in a desired orientation to bring or place it in a previously taken (and previously marked) To reset alignment, and the chosen one Adjustment is maintained accurately and without the risk of misalignment.

The The invention will be better understood with the aid of the following Description with reference to the attached schematic drawing set which an example of an embodiment this device for holding and adjusting the alignment a reflector for a lighting fixture embedded in the floor shows:

1 Fig. 12 is a vertical sectional view of a lighting fixture to be embedded in the floor with a device for holding and adjusting the orientation of a reflector according to the present invention;

2 Fig. 12 is a perspective view showing the reflector and its holder and alignment device;

3 is a side view of this device, the arrow F of 1 following.

The in 1 illustrated lighting fixtures (where only its upper part is shown) is intended for insertion into the ground, this figure in detail the body of the lamp 2 shows, which is removably embedded in the interior of a recessed in the floor mounting trough (not shown).

The interior of the lighting fixture 2 forms a main chamber 3 in which a lamp 4 and a reflector 5 are housed, with which a more or less open or concentrated light beam can be generated, which is directed upwards and so the outer environment through the upper lens (not shown) of the lighting fixture through. The lamp 4 and the reflector 5 are upper half of a horizontal support plate 6 mounted inside the lighting fixture 2 sitting at a certain height above the floor of this body.

• – einerseits bezüglich der Drehung um die zentrale vertikale Achse A des Beleuchtungskörpers 2 um eine komplette Umdrehung, das heißt um 360°;
• – andererseits bezüglich der Neigung bezogen auf die Vertikale; das heißt, dass die zentrale Achse B des Reflektors 5 mit der vertikalen Achse A einen spitzen Winkel α bilden kann, der beispielsweise zwischen 0° und 30° variabel ist (1 zeigt die zwei äußersten Winkelpositionen, die durch Verstellen der Neigung erreicht werden können, jeweils in Strichpunktlinie und durchgehender Linie).

The invention relates in detail to the mounting of the reflector 5 which can be aligned in this case:

• - On the one hand with respect to the rotation about the central vertical axis A of the lighting fixture 2 by one complete revolution, ie by 360 °;
• - on the other hand, with respect to the inclination relative to the vertical; that is, the central axis B of the reflector 5 with the vertical axis A can form an acute angle α, which is variable, for example, between 0 ° and 30 ° ( 1 shows the two extreme angular positions that can be achieved by adjusting the inclination, each in dashed line and solid line).

Related to the 2 and 3 you can see that the reflector 5 on a first lyre-shaped carrier 7 is rigidly attached. More specifically, the base of the reflector 5 through a screw 8th with Mother 9 at the center of the carrier 7 fastened, whose two opposite arms 7a and 7b are directed upwards and on both sides of the reflector 5 extend.

The first lyre-shaped carrier 7 is in turn in a second lyre-shaped carrier 10 inserted, whose middle part under the reflector 5 lies and whose two opposite arms 10a and 10b are directed upward and also on both sides of the reflector 5 extend.

The upper ends of the two arms 7a and 7b of the first lyre-shaped carrier 7 are each by lateral pivot 11 movably mounted with elastic discs at the corresponding upper ends of the two arms 10a and 10b of the second lyre-shaped carrier 10 , The two side pivots 11 thus define a horizontal axis of rotation C following the first lyre-shaped carrier 7 pivotable with respect to the second lyre-shaped carrier 10 is mounted. This pivotal movement, indicated by an arrow F1, allows the inclination (with respect to the vertical axis A) of the reflector 5 to adjust.

The second lyre-shaped carrier 10 its middle part is horizontally just above the horizontal support plate 6 arranged and with this plate 6 through a central pivot 12 connected, which follows the vertical axis A. The pivot 12 consists of a screw 13 with locknut 14 that the plate 6 and the carrier 10 traversed vertically; a flat disc 15 is between the plate 6 and the carrier 10 inserted, and an elastic disc 16 , in particular a corrugated spring washer, is between the carrier 10 and the mother 14 inserted. The thus assembled elastic pivot 12 allows the rotation of the carrier 10 according to the ensemble of the two bearers 7 and 10 and the reflector 5 to the vertical axis A, as an arrow F2 shows, to the rotation of the reflector 5 adjust.

At the lower middle part of the second lyre-shaped carrier 10 , in particular in the region of the central pivot 12 , is an angled metal rod 17 attached in the form of a very flexible flat band. The angled metal rod 17 extends in a vertical plane that is perpendicular to the vertical plane, which is the second lyre-shaped carrier 10 contains. This angled metal rod 17 has a substantially horizontal first part 17a just above the horizontal plate 6 extends, and a second part 17b who is the first part 17a extended and extends up to the level of the horizontal axis of rotation C upwards. The upper part of the second part 17b of the staff 17 is bent in a circular shape, which is centered on the horizontal axis of rotation C.

The angled metal rod 17 is under its substantially horizontal part 17a with a vertical fixing pin 18 provided, which is directed downward. In the upper rounded area of the second part 17b of the metal bar 17 a series of rectilinear circular holes are arranged which have regular separation distances, for example six holes 19 , arranged at angular intervals of 6 ° (the tips of the relevant angle are on the horizontal axis of rotation C).

In the horizontal plate 6 is a series of circular holes 20 executed in large numbers, one centered on the vertical axis A. Following are arranged circle and are separated from each other at regular intervals. In this case, for example, there are sixty holes 20 provided, which are separated by angular intervals of 6 °.

The vertical fixing pin 18 of the metal bar 17 is provided to with the holes 20 The horizontal plate cooperate by acting solely by the effect of the elasticity of the rod 7 in one of these holes 20 locks. The second lyre-shaped carrier 10 can be fixed so after rotation in a selected angular position, (in the individual example considered here) every 6 ° positioning in a horizontal plane is possible.

Finally, outside is on the periphery of the reflector 5 in a vertical plane that is perpendicular to the horizontal axis of rotation C, a Einstellstab 21 attached. The adjusting rod 21 which is bent upwards is also a very flexible flat band. This adjusting rod 21 is outside with a fixing pin 22 Mistake.

When the ensemble is mounted, it is at the reflector 5 fixed adjustment rod 21 opposite the upwardly facing second part 17b the angled metal rod 17 that with the second lyre-shaped carrier 10 is firmly connected. The fixing pin 22 on the adjusting rod 21 can sit alone by the effect of the elasticity of this rod 21 in one of the holes 19 of the second part 17b of the metal bar 17 engage in order to ensure fixation of the reflector in an inclined position, (in the individual example considered) with a possible positioning in a vertical plane every 6 ° between the limits 0 ° and 30 °.

It is thus understood that by the combination of the devices described above, the orientation of the reflector 5 , as a result of the associated lamp 4 , both in terms of inclination (angular position with respect to the horizontal axis C) and with respect to the rotation about the vertical axis A can be fixed and held.

Wenn anschließend der Einstellstab 21 losgelassen wird, kann der Fixierstift 18 in ein anderes, passend gewähltes Loch 20 der waagerechten Platte 6 eingreifen. Die Einstellung bezüglich der Drehung um die vertikale Achse A ist somit durchgeführt.
• – Indem der Einstellstab 21 waagerecht nach dem Innern der Beleuchtungseinrichtung gezogen wird, und aufgrund der Flexibilität dieses Stabes 21, rutscht der auf diesem Einstellstab 21 sitzende Fixierstift 22 aus dem Loch 19 des Metallstabes 17, in dem er gesteckt hat. So wird der Reflektor 5 frei in der Drehung um die horizontale Achse C, wodurch seine Neigung eingestellt werden kann. Wenn er seine neue geneigte Stellung erreicht hat, wird der Reflektor 5 fixiert, indem der Einstellstab 21 losgelassen wird, so dass sein Fixierstift 22 in ein anderes Loch 19 des Metallstabes 17 eingreift.

To the orientation of the reflector 5 with respect to the vertical axis A and / or with respect to the inclination, the adjusting rod becomes 21 captured at its upper free end and this adjustment rod 21 is drawn vertically and / or horizontally, in the following steps:

• - By adjusting rod 21 is pulled vertically upward, and due to the appropriate flexibility of the two rods 17 and 21 , the vertical fixing pin slips 18 out of the hole 20 the horizontal plate 6 in which he has stuck, which makes it possible to ensemble of the two lyre-shaped straps 7 and 10 , so that the reflector 5 to rotate the vertical axis A. When then the adjustment rod 21 is released, the fixing pin 18 in another, appropriately chosen hole 20 the horizontal plate 6 intervention. The adjustment with respect to the rotation about the vertical axis A is thus performed.
• - By adjusting rod 21 horizontally drawn to the interior of the lighting device, and because of the flexibility of this rod 21 , slipping on this adjustment bar 21 seated fixing pin 22 out of the hole 19 of the metal bar 17 in which he was stuck. This is how the reflector works 5 free in rotation about the horizontal axis C, whereby its inclination can be adjusted. When he has reached his new inclined position, the reflector becomes 5 fixed by the adjusting rod 21 is released, leaving its fixing pin 22 into another hole 19 of the metal bar 17 intervenes.
