    Luminaire, arrangement for a grid ceiling, method for mounting a luminaire, method for dismantling a luminaire, and dismantling tool
    FIELD OF THE INVENTION
    The present invention relates to a luminaire for mounting in a grid ceiling. Furthermore, the invention relates to an arrangement for a grid ceiling, a method for Montie¬ren a lamp, a method for disassembling a mounted luminaire, and a disassembly tool.
    TECHNICAL BACKGROUND
    In particular, interiors of buildings, such as offices or business premises, are often equipped with suspended ceilings. Such ceilings can be made with a support structure and with ceiling panels which form part of a so-called grid ceiling system.
    To illuminate an interior equipped with a suspended ceiling, suitable luminaires can be mounted in the area of the ceiling. In particular, such lights can be integrated for this purpose in the suspended ceiling.
    Due to the mounting position in the ceiling area, which frequently entails work for the installer above the head height, it would be desirable if the installation of the luminaire in the area of a grid ceiling could be effected as quickly and simply as possible and at low cost. In addition, it would be desirable, albeit a dismantling of a mounted
    Lamp - for example, in a conversion of the interior or if for other reasons, the light should be removed - could be done in a simple manner and with minimal time and ge¬ringem personnel costs.
    SUMMARY OF THE INVENTION
    Against this background, the object of the invention is thus to provide a luminaire which can be easily mounted in the area of a grid ceiling and, preferably, can also be easily dismantled again. In addition, a grid ceiling should be improved accordingly. It is an object of the invention to provide a method for simplex and rapid mounting of such an improved luminaire and to provide a method for the simple and rapid demounting of such a luminaire and a suitable tool haul.
    This object is achieved according to the invention by a luminaire having the features of claim 1 and / or by an arrangement for a grid ceiling having the features of claim 10 and / or by a method having the features of patent claim 13 and / or by a method having the features of claim 14 and / or by a disassembly tool having the features of claim 15.
    Accordingly, a luminaire for mounting in a grid cover is proposed, wherein the luminaire has at least one snapper. According to the invention, the at least one snapper is arranged on the luminaire and designed such that the at least one snapper automatically snaps a section of an element of the grid ceiling when mounting the luminaire. By the automatic snapping the at least one snapper engages behind the portion of the element of the grid ceiling to hold the lamp to the grid ceiling.
    Furthermore, an arrangement for a grid corner is proposed according to the invention, the arrangement having at least one ceiling profile element and at least one such inventive luminaire. In this case, at least one movable latch of the at least one luminaire engages behind a section of the ceiling profile element of the grid ceiling, wherein the at least one luminaire is held on the grid ceiling by means of the gripping-behind of the ceiling profile element.
    The invention further provides a method of mounting a luminaire according to the invention in a grid ceiling. The method comprises the following steps: a luminaire according to the invention is provided; and - the luminaire is moved relative to at least one element of the grid ceiling, which is arranged on a predefined and the element for the formation of the grid ceiling Bestim¬mungsort and fixed at the destination, that at least one snap of the lamp behind ei¬nen section of Elements of the grid ceiling automatically ein¬ snaps and engages behind the section of the element of the grid ceiling by the automatic snapping to hold the light on the grid ceiling.
    In addition, the invention provides a method for demonstrating a lamp according to the invention, which is mounted in a Ras¬terdecke ready. The method has the following steps: A predetermined disassembly tool is moved in an insertion direction from a visible side of the grid ceiling into a
    Gap between an element of the grid ceiling and the lamp is inserted; - A movable gate of the lamp, which engages behind a portion of the element of the grid ceiling for holding the light on the grid ceiling is attacked by the disassembly tool; and pulling on the dismantling tool takes place substantially counter to the insertion direction in order to apply a force to the snapper, which causes the catch to disengage from the section of the element; Disassembly tool in the gap zwi¬ the element and the lamp out.
    Furthermore, a disassembly tool for dismantling a lamp according to the invention and mounted in a grid ceiling is proposed, wherein the disassembly tool can be made in particular for the disassembly of the lamp by means of the above method according to the invention. The dismantling tool has a first section, a second section connected to the first section and laterally extending transversely of the first section, and a tongue connected to the second section. The tongue extends in substantially the same direction as the first portion away from the second portion. The first section is, for example, designed as a handling section for handling the dismantling tool. A portion of the first portion, the second portion and the tongue define a recess, wherein a portion of the recess is formed as a snap-receiving portion for receiving a portion of a snap of the lamp. When the snapper is received in sections in the snapper receiving area and abuts the second portion of the dismounting tool, the tongue protrudes in the direction of extension of the tongue from the second section past the snapper.
    An idea on which the present invention is based is to be able to use the geometry of at least one element of a roof cover in order to secure the lamp in the region of the grid ceiling by means of an automatic snap-in of a snapper provided on the lamp Luminaire considerably simplified, which can prove to be advantageous especially with a larger number of luminaires to be mounted and with large ceiling areas, such as these may occur in larger office or business premises. A grid ceiling with an inventive arrangement can thus be installed with reduced time and cost. In addition, visible and conspicuous fastening elements for the luminaire or the like are not required from a visible side of the grid ceiling, so that the grid ceiling with the mounted luminaire can advantageously be made particularly appealing from the aesthetic point of view. The disassembly method and disassembly tool provided by the invention allow for a quick and safe disassembly of the luminaire when needed. The protrusion of the tongue of the dismantling tool on the Schnapper also avoids snagging and jamming of the dismantling tool when releasing the snapper, since the ausge¬ formed in this way tongue during the unlocking advantageously in ei¬nem gap between the lamp and the element of the grid , which the Schnapper engages behind, can be guided.
    As an element of the grid ceiling, an element of the grid ceiling will be generally referred to herein, which component may be formed in a variety of manners. For example, the element could be profile-like or rail-like, such as a ceiling profile element, but instead also panel-like or plate-like, such as in the form of a ceiling plate with a cut-out for receiving the light or the like, or otherwise.
    Advantageous embodiments and further developments of the invention will become apparent from the subclaims and from the description with reference to the figures of the drawing.
    In one embodiment, the at least one snapper has a sliding ramp. The slide ramp is arranged and aligned such that it faces the grid ceiling when mounting the lamp and is inclined to a direction along which the lamp is to be mounted for mounting in the grid ceiling. In this way, the mounting of the light can be further facilitated by in the assembly process, the element of the grid ceiling in regions on the Gleitrampegleiten and thereby push back the snapper.
    In an advantageous embodiment, the at least one snapper is spring-loaded. The snapper thus snaps reliably behind the portion of the element of the grid ceiling.
    In one embodiment, the at least one snapper is der¬art arranged and spring-loaded, that it returns in the Einschnappenselfbstktivig in a position in which the min¬destens a snapper on an edge of the lamp, insbeson¬dere a lateral edge of the same projecting. This facilitates a later release of the catch for dismantling the lamp.
    In one embodiment, the lamp further comprises a Schnapper¬ housing. Here is the at least one snapper in the
    Snap housing movably guided. The snap housing can thus enable reliable, defined guidance of the snapper.
    In a preferred embodiment, the at least one snapper is slidably guided in the snapper housing. A sliding guide of the snapper can be realized relatively simple and space-saving. Furthermore, in this case in particular a sufficiently large holding surface of the catch for holding the luminaire can be brought into contact with the element in a simple manner.
    According to a further development, the at least one snapper and the snapper housing, in which the at least one snapper is guided, form components of a snapping unit. Furthermore, in this development, the lamp has at least one groove, wherein the snap unit is fixed in the groove. The sniffer unit can therefore be advantageously pre-qualified and fixed during assembly of the luminaire at the desired position within the groove.
    In one embodiment, the snap unit is clamped in the groove and thereby festge¬legt at least along the groove in this. Clamping the snap unit in the groove can allow reliable frictional locking of the sniffer unit against displacement along the groove, avoiding the introduction of bores and the like into the lamp for securing the snapping unit. In addition, if necessary, the clamp can be released again, and the snap unit can be moved in the groove and clamped again elsewhere.
    In a further embodiment, the luminaire has a plurality of snappers, wherein at least two of the snappers are arranged on opposite sides of the luminaire. As a result, the lamp can advantageously engage behind elements of the grid ceiling, which are adjacent to opposite sides of the lamp, in order to hold the lamp even more reliably on the grid ceiling.
    In particular, the plurality of snapper may be formed in the same way. In the production of the luminaire and the arrangement for the grid ceiling, this allows further cost savings due to the smaller number of different individual parts to be manufactured.
    In a preferred development, a plurality of snap-action units can be provided, which each comprise a snap-action housing and a respective snapper and are each further fixed to the light.
    For this purpose, in a refinement of the luminaire, at least two grooves can be provided, which are arranged on different sides of the luminaire and intended for receiving the snap-action units. Such an arrangement of the grooves, together with a plurality of snap units, can offer versatile possibilities of arranging the snapper on the lamp.
    According to a further development, the luminaire has at least two snap-action lugs spaced apart on one side of the luminaire along a longitudinal direction of the luminaire and formed in substantially the same way. This configuration makes it possible to hold even a relatively elongated trained light even more reliable on the grid ceiling. In the case of particularly long lamp lengths, in particular more than two snappers arranged at a distance from one another on a longitudinal side of the lamp can be useful, in order to avoid sagging of the lamp under its own weight.
    In a preferred embodiment, the luminaire is equipped with at least four latches, which are preferably designed and guided in a similar manner. According to this embodiment, two of the snappers are arranged at a distance from one another on a first side of the luminaire, while two further ones of the snappers are arranged at a second side of the luminaire spaced apart from one another. In this way, without being tilted during assembly, the luminaire can be easily inserted between two elements of the grid ceiling and reliably mounted to the grid ceiling by snapping the snaps behind sections of these elements.
    Advantageously, the snapper may be formed in one embodiment with ei¬nem metal material. In this way, a robust and resilient snapper can be achieved.
    In a preferred embodiment, the element of the grid ceiling, which engages behind the snapper, to a profile, in particular a ceiling profile element of Ras¬terdecke.
    A ceiling profile element is to be understood in the context of the present appli cation generally as a profile element, which forms a part of the grid ceiling.
    According to a preferred embodiment, the ceiling profile element can be designed as a component of a supporting structure of the roof decking, wherein the ceiling profile element can be designed in particular to support ceiling elements of the roof decking. With this configuration, a ceiling profile element of the support structure can also be advantageously used for the simple and rapid attachment of the luminaire. The ceiling elements of the grid ceiling can be designed, for example, as ceiling panels, ceiling panels or the like. In particular, it can be provided that the ceiling profile element can be arranged and fixed separately from the ceiling elements at its destination, in the area below a raw ceiling.
    In an alternative embodiment, the Deckenprofilele¬ment in a ceiling element, such as a ceiling panel o-a ceiling plate, integrated or be firmly verbun¬den with this. For example, in a variant of this embodiment, the ceiling element can be provided with a cutout, in the edge region of which one or more ceiling profile elements are provided and connected to the ceiling element, for example in the manner of a shaft or the like.
    According to one embodiment, the ceiling profile element is at least inversely T-shaped in a region of its cross section. In this embodiment, the at least one catch of the at least one luminaire partially engages behind a flange section of the inverted T-shaped region. Such a ceiling profile element can be advantageous, for example, in terms of its mechanical strength. In other embodiments, however, the cross section of the ceiling profile element may instead be designed differently.
    According to a further embodiment, the arrangement further comprises at least one ceiling element, which rests in sections on the ceiling profile element, wherein the at least one
    Luminaire on a visible side of the grid ceiling with the Decken¬element or the ceiling profile element or both in particular may be substantially flush. Such a flush arrangement can be preferred from the aesthetic point of view.
    The ceiling profile element can be formed in a development as einschienenartiges component, in particular of a Metallwerk¬stoff.
    In a further embodiment it can be provided that at least two elements of the grid ceiling, in particular two ceiling profile elements, each at a predefined destination, which is in each case assigned to the element for the formation of the grid ceiling, are arranged and fi xed at the destination. For example, the elements can be arranged and fastened in a predefined distance adapted to the dimensions of the luminaire. In this embodiment, the lamp is inserted for mounting the same zwi¬ the at least two elements. This is done so that the at least one snapper automatically snaps into place behind a portion of one of the grid ceiling elements as it projects the light and thereby engages a portion of the grid ceiling element to hold the light to the grid ceiling.
    According to a further embodiment of the assembly method, a luminaire having at least two latches arranged on opposite sides of the luminaire can advantageously be inserted in the manner between the at least two elements such that each of the latches snaps behind a section of a relative one of the two elements.
    In a further development of the method for dismantling the light, a force is exerted on the sliding ramp of the snap when pulling by means of the predetermined disassembly tool. In particular, by pulling on the dismantling tool substantially along the direction in which the luminaire is held by means of the snapper, for example along a direction vertical to the bottom, a force can be exerted on the snapper by means of the sliding ramp shifts the snapper transversely to this direction of pull and thereby disengages with the engaged behind element of the Ras¬terdecke.
    In one embodiment of the dismounting tool, a limitation of the snap-action receiving area is formed in sections by an end edge formed on the second section and edge portions of the first section and of the tongue that are substantially parallel to one another. Further, in this embodiment, the recess continues with inclined edge portions of the first portion and the tongue adjoining the parallel edge portions of the first portion and the tongue, respectively. Here, the oblique edge portions are inclined to the substantially parallel edge portions of the first portion and the tongue inclined, and the snapper is inserted through a gap between the oblique edge portions in the snap-pick-up area. The parallel edge sections, which in particular can run substantially perpendicular to the closure edge and in the intended pulling direction of the demounting tool, make it possible for the closing edge of the recess to slide over the sliding ramp of the recess in order to release the latch. The oblique edge portion of the tongue allows a simplified insertion of the snappers into the gap and the Schnapper Aufnahme¬ area. This is useful in releasing the snapper by inserting the disassembly tool through a gap between the lamp and the undercut element of the grid ceiling, in which case the snapper will often be barely visible from a visible side of the grid ceiling. The oblique edge portion of the first section can help, when pulling the disassembly tool with the help of the handling section, effectively apply the tensile force to the snapper and avoid moments around the snapper, which could lead to jamming or jamming of the disassembly tool.
    In a further embodiment of the dismantling tool, the two oblique edge portions of the first portion and the tongue may be substantially parallel to each other.
    According to an advantageous development, the disassembly tool can be made plate-like, in particular from a flat material, for example a sheet metal. Such a flat disassembly tool is advantageous for insertion into a gap between the luminaire and the element of the grid covers in dismantling the luminaire.
    In one embodiment, the disassembly tool may be stamped out of a metal sheet, for example a sheet formed with a steel or a stainless steel. A der¬art trained tool is inexpensive to produce.
    The above refinements and developments can, if appropriate, be combined with one another as desired. Further possible refinements, developments and improvements of the invention also include combinations of features of the invention described above or below with regard to the exemplary embodiments which are not expressly mentioned Here, the expert also individual aspects as
    Add improvements or additions to the respective basic form of the present invention.

    DESCRIPTION OF EMBODIMENTS
    Fig. 1 shows a lamp 1 for mounting in a grid deck according to an embodiment of the present invention.
    The luminaire 1 has a substantially rectangular basic shape. A longitudinal direction of the luminaire 1 is indicated in FIG. 1 by the reference symbol x, a transverse direction of the luminaire 1 by the reference numeral y. In the example shown, a width B of the luminaire 1 may preferably be approximately B = 100 mm and a length L of the luminaire 1 approximately L = 1200 mm, it being understood that these dimensions are given here by way of example only and the width B and the length L may be chosen in a variety of useful and advantageous variants. For example, with a width B of about B = 100 mm, the length L according to an alternative embodiment could be about L = 2400 mm.
    The luminaire 1 is shown in perspective in FIG. 1 in such a way that the upper side of the luminaire 1, which is not visible in an assembled state of the luminaire 1, can be seen in the figure.
    In the area of this upper side, the luminaire 1 has an electrical connection device 4. Further, in Fig. 1, a cover 5, which may be embodied for example as a cover plate, recognizable. The cover 5 covers in particular electrical and / or electronic components of the luminaire 1.
    As can be seen from FIGS. 1 and 2, the luminaire 1 has grooves 8 on opposite longitudinal sides 7a, 7b, which extend in the longitudinal direction x of the luminaire 1 over the entire length L and are open to the outside. In the example shown, the cross section of each of the two grooves 8 is substantially constant and substantially T-shaped along the longitudinal direction x. In the embodiment shown in the figures, the legs of the T-shape pointing upwards and downwards in the figure are made comparatively short While an opening 8b of the respective groove 8 is relatively wide. Undercut 8a provided on the side of the opening 8b of the groove 8 are thus relatively flat in this example.
    In the grooves 8 a total of four snap units 10 are arranged in the lamp 1 shown in FIGS. 1 and 2. Of the snapping units 10, two are arranged on a first longitudinal side 7a of the luminaire 1 and two further on a longitudinal side 7a opposite the second longitudinal side 7b of the luminaire 1. In Fig. 1, only the two snap units 10 are visible on the side 7a, one of which is located adjacent to one end portion 2 of the luminaire 1 and the other to an opposite end portion 3 of the luminaire 1. The Schnappereinhei¬ten 10 on the page 7a are thus spaced along the longitudinal direction xvon. The two snap units 10 on the side 7b are not visible in Fig. 1, but in the example shown with respect to a center axis M of the lamp 1 in the longitudinal direction x arranged in approximately symmetrical manner to the snapping units 10 on the side 7a.
    If the length L in variants of the embodiment z. B. greater than L = 1200 mm selected, z. B. to 2400 mm, then at each longitudinal side 7a, 7b of the lamp 1 three or four vonei¬nander objectionable Schnappereinheiten 10 may be arranged, wo¬ out there may be a total of six or eight Schnapperein¬heiten 10 per lamp. An even greater number of snap units 10 per luminaire would also be conceivable.
    The snap units 10 of the luminaire 1 are designed in the same way. Each of the snap units 10 has a moveable snapper 13 and a snapper housing 15, wherein the catcher 13 is arranged and guided in the associated snapper housing 15 so as to be displaceable in a straight line. In each of the catcher housings 15 there is further provided a spring element not visible in the figures, which acts on the snapper 13 with a spring force, whereby it is spring-loaded. The snapper 13 is made in the embodiment of ei¬nem metal material.
    The snapper housing 15 are designed such that they can be pushed along the longitudinal direction x of the lamp 1 in the grooves 8. After insertion into the groove 8, the snapper housings 15 are each preferably clamped in the respective groove 8 by means of one or more screws 19 and in this way the respective snap unit 10 is fixed to the lamp 1. While the undercuts 8a hold the snapper housing 15 in the transverse direction y, the snap-action housing 15 is frictionally fi xed in the groove 8 in the longitudinal direction x. The clamping fixation of the snap units 10 in the groove 8 offers a variety of possibilities to position the Schnapperein¬ 10.
    In the state shown in FIGS. 1 and 2, the snappers 13 of the snap-action units 10 project outwardly beyond an associated lateral edge 6 in the region of the longitudinal side 7a or 7b of the luminaire 1 under the effect of the spring force, while the snapper housings 15 project beyond the latter lateral edge 6 not survive.
    FIGS. 3 to 5 show a grid ceiling 20 with ceiling elements 21, which are panel-like in the example shown, and with a supporting structure for supporting, in particular, the ceiling elements 21. The supporting structure contains ceiling profile elements 28, for example made of metal can be. A visible side of the grid ceiling 20 is designated by the reference S. In the figures, the grid ceiling 20 is shown only in regions, with only sections two ceiling profile elements 28 and some ceiling elements 21zu can be seen. The two cover profile elements 28 shown in FIGS. 3 to 5 run as profile rails, for example, in a substantially horizontal direction and substantially parallel to one another at a distance A, as indicated in FIG. 3 and additionally in FIG.
    In Fig. 3, a lamp 1 according to the Ausführungsbei¬spiel in a position below the two Deckenprofilele¬mente 28 is also shown. The luminaire 1 is intended to be mounted in the intermediate space between the two illustrated ceiling profile elements 28 such that a bottom of the luminaire 1 terminates approximately flush with the ceiling elements 21 and the ceiling profile elements 28. On this underside, the luminaire 1 has a light exit region 9, which in this example is substantially rectangular. For example, the light exit area 9 may be formed with a translucent disc or plate which light LL, see FIG. 5, which is provided by light-generating devices of the luminaire 1, not shown in the figures, for the illumination of the room to be illuminated and towards the bottom of the luminaire lets emerge. However, it is understood that the light exit region 9 can alternatively be designed in many other ways.
    Such as As can be seen from Fig. 6, the Deckenprofilelemen¬te 28 are in some sections inverted T-shaped inversely formed with a web portion 31 and a belt or Flanschab¬ section 34. The flange portion 34 itself continues in a groove-like profile 36 with an inverted T-shaped geometry. In the embodiment shown, the flange portion 34 is substantially perpendicular to the stile portion 31.
    The sliders 13 which are displaceable along the transverse direction y each have a holding surface 45 which extends essentially parallel to the x-y plane spanned by the longitudinal direction x and the transverse direction y, see FIGS. 1 and 6. A second surface of the snapper 13, however, is aligned obliquely to the xy plane and forms a sliding ramp 46. Advantageously, the snapper 13 are further provided with guide grooves 55, in the for a further improved sliding guide the snapper 13 associated projections 64 of the Schnap¬pergehäuses 15 sliding intervention.
    For mounting, the lamp 1 is moved in the vertical direction V upwards on the ceiling profile elements 28, see Fig. 3. The slide ramps 46 of the snapper 13 are in this case the Ras¬terdecke 20 facing and get at continued Einschie¬ben the lamp 1 between the ceiling profile elements 28th In contact with the ceiling profile elements 28. As a result, the spring-loaded snapper 13 are pressed against the respective spring in the direction of the arrow 51 parallel to the transverse direction y in the respective Schnappergehäuse 15 by the action of inclined against the vertical direction V Gleit¬ ramps 46, see the Dildildarstellung Dl in Fig. 4.
    Upon further insertion of the luminaire 1 between the ceiling profile elements 28 in the vertical direction V, the catchers 13 reach behind parts of the flange sections 34 of the ceiling profile elements 28 located on both sides of the luminaire 1, see FIG. 6. The snapper 13 automatically moves behind under the action of the spring force the respective flange portion 34 and engage behind this area. In other words, the snapper 13 moves under the action of the spring element back to their respective positions in which the snapper 13 over the edges 6 survive.
    In this way, the lamp 1 is securely held. There is therefore no need for a tool, in particular no screwdriver or the like, to be able to mount the luminaire 1 in the grid ceiling 20, but the luminaire 1 is simply inserted between the profile elements 28 until the snappers 13 snap in. Advantageously, the installer can recognize on the basis of a perceptible "click" or "snap" sound when the snapper 13 snaps in that the snappers 13 have engaged behind the respective profile 28 assigned to them.
    As can also be seen from FIG. 6, sections 66 of the ceiling elements 21 rest on partial regions of the ceiling profile elements 28 facing away from the luminaire 1. The Deckenprofil¬elemente 28 form part of the support structure for the grid ceiling 20. In the grid ceiling 20, the lamp 1 in the illustrated embodiment between the Deckenprofil¬elementen 28 solely by the action of the four snapper 13, which engage behind the profile elements 28 held. The ceiling profile elements 28 and the luminaire 1 form components of an arrangement 23 for the grid ceiling 20.
    It should be pointed out that a plurality of luminaires 1 in their longitudinal direction x can subsequently be mounted in the same way between the ceiling profile elements 28.
    Dismounting the luminaire 1 is shown by way of example in FIGS. 7, 8 and 9. For disassembling the lamp 1, a disassembly tool 78 or a plurality of similar disassembly tools 78 are used, see FIG. 7. The disassembly tool 78 is designed as a sheet metal part, for example punched out of a steel sheet, with a sheet thickness t of for instance approximately t = 1 mm , The dismantling tool 78 is used to Lö¬sen or unlocking the snapper 13 and thus can also be referred to asEnertiegelungsblech.
    As particularly shown in detail D2 in FIG. 8, the disassembly tool 78 has a first portion 79, a second portion 82 connected to the first portion 79, and a tongue 91 connected to the second portion 82. The first section 79 is elongate, extends along a main extension direction Hl, and is provided with a circular hole 89 in a first end region 80. The section of the first section 79 provided with the hole 89 forms a handling section 100 of the tool 78.
    In a second end region 81 of the first section 79, the second section 82 adjoins the first section 79, wherein the second section 82 extends transversely to the first section 79 and laterally therefrom along a main extension direction H2. In the same direction, the first section 79 extends at an end 83 of the second section 82 remote from the end region 81 to a tongue 91, which is narrower and shorter than the first section 79, away from the second section 82. A main extension direction H3 of the tongue 91 is substantially parallel to the main extension direction Hl of the first portion 79. The first section 79, the second section 82 and the tongue 91 thus form approximately an asymmetrical U-shape, in which a leg is significantly shortened and narrower.
    In order to dismantle the luminaire 1, the dismantling tool 78 is inserted in the direction of the arrow 85, see FIG. 7, from the visible side Sin, a gap 25 between the lateral edge 6 of the luminaire 1 and the adjacent ceiling profile element 28. In the embodiment, the insertion essentially takes place along the vertical direction V. In order to find the position of the catcher 13 with the luminaire 1 mounted from the visible side Sher, the dismantling tool 78 can be moved along the luminaire 1 through the gap 25.
    In this way, the snapper 13 can be found by means of the disassembly tool 78, i. the dismantling tool 78 meets the snapper 13. The snapper 13 then comes to lie by a slight pulling down of the disassembly tool 78 against the arrow 85 in a Schnapper Aufnahme¬ area 105 of the disassembly tool 78 and is thus "captured", the disassembly tool 78 engages over the snapper 13, see Fig. 8.
    The snap pick-up area 105 is located between the tongue 91 on the one hand and the first portion 79 on the other hand and is formed by a part of a recess 102 which is open to an outer edge of the disassembly tool 78 and by a portion of the first portion 79, the second Ab¬ section 82 and is limited by the tongue 91. Specifically, an exclusion edge 103 formed on the second portion 82, an edge portion 106 of the first portion 79 extending substantially perpendicular to the end edge 103, delimits an edge portion 107 of the tongue 91 extending essentially to the end edge 103 of the tongue 91 End edge 103 inclined extending oblique edge portion 108 of the first portion 79 and also inclined to the VerBrand 103 sloping edge portion109 of the tongue 91, the recess 102. The two edge portions 106 and 107 extend away from the end edge 103, where the edge portion 108 to the edge portion 106 and the edge portion 109 to the edge portion 107 connect.
    The edge portions 106 and 107 are substantially parallel to each other. Also, the edge portions 108 and 109 may be formed substantially parallel to each other. The snap pickup area 105 is partially bounded by the end edge 103 and the edge portions 106 and 107.
    In the use state of the dismantling tool 78, see the detail D2, the end edge 103 extends substantially perpendicular to a pulling direction, which in the example shown corresponds to the vertical V.
    As the detail D2 in Fig. 8 makes clear, the tongue 91 is along its main extension direction H3 on the Schnapper13 in the figure downwards, d. H. in the pulling direction, thereby extends past the snapper 13, when the catcher 13 is partially received in the snap-receiving area 105 and, as in the detail D2, abuts against the terminating edge 103 formed on the second section 82.
    The threading of the disassembly tool 78 in such a manner that the catcher 13 comes to lie in the snap-action receiving portion 105 is facilitated by the oblique edge portion 109 formed on the tongue 91, by which the tongue 91 slightly tapers at its end.
    The oblique edge portion 109, as shown in Fig. 8, facing the first portion 79. The oblique edge portion 108 formed on the first portion 79 faces the oblique edge portion 109. When threading the disassembly tool 78, the snapper 13 slides through a gap 111 between the oblique edge portions 108 and 109 into the snap-receiving area 105.
    In order to release the catch 13, the dismantling tool 78 is pulled down in a direction substantially parallel to the vertical direction V along the arrow 120, see FIG. 9, i. opposite to the direction in which the disassembly tool 78 was inserted into the gap 25. The first portion 79 and the tongue 91 are laterally, i. in the transverse direction y, passed through the gap 25. As a result of the tongue 91 protruding beyond the catch 13 as well, when the closing edge 103 abuts the sliding ramp 46 of the snapper 13, reliable guidance of the dismounting tool 78 in the gap 25 is achieved.
    The trailing edge 103 of the second portion 82 slides in pulling with the help of the hole 89 in some areas over the inclined sliding ramp 46 of the snapper 13. The train in the direction of arrow 120 and the simultaneous support and guidance of the disassembly tool 78 in the gap 25, in particular the Deckenprofilelement28, cause a back-pressing Snapper 13 against the spring force into the snapper housing 15 inside. The snapper 13 comes in this way out of engagement with the Deckenprofil¬element 28, whereby the lamp 1 can be solved.
    The necessary tensile force in the direction 120 can be applied by a fitter by hand. The hole 89 serves here to insert a finger in order to be able to pull on the dismounting tool 78 more effectively. By means of the oblique course of the edge section 108 it can be achieved that the line of action of the tensile force is not excessively offset laterally relative to the snapper 13, whereby moments about the snapper 13 are reduced and the tensile force can be applied more effectively to the snapper 13, i. you pull more centric below the snappers 13.
    In FIG. 6, which shows the luminaire 1 mounted in the grid ceiling 20, the two gaps 25 between the luminaire 1 and the ceiling profile element 28 on the one and the other side of the luminaire 1 and the gap widths S1 and S2 of both gaps 25 are characterized. In this case, the luminaire 1 in FIG. 6 does not sit exactly in the middle between the two ceiling profile elements 28, S1 is therefore greater than S2. In Fig. 6, S1 is greater than the sheet thickness t, i. In the left-hand gap 25 with the width S1 in FIG. 6, the disassembly tool 78 can be inserted to release the catch 13.
    In the embodiment shown in the figures, which each have two snapper 13 on each of the longitudinal sides 7a and 7b of the lamp 1, two disassembly tools 78 can be used at the same time. In this case, the two snappers 13 arranged on the same longitudinal side 7a or 7b of the luminaire 1, in FIG. 6 on the side of the gap 25 with the gap Sl, are "captured" by means of a respective dismantling tool 78 ". Attacked, and then solved, for example, by simultaneously pulling on both disassembly tools substantially at the same time. In the configuration shown by way of example in FIG. 6, the luminaire 1 can already be tilted out of the grid ceiling 20 and removed after loosening the catch 13 of the left-hand side of the luminaire 1 in the figure.
    The width B of the luminaire 1 and the distance A of the Deckenprofil¬elemente 28 may be selected taking into account the dimensions of the Profilelemente 28 in such a way that the Spalt¬weiten S1 and S2 - preferably taking into account possible deviations of the mounted ceiling profile elements 28 of the desired position - at least are greater in total than the sheet thickness t of the disassembly tool 78, expressed differently, (S1 + S2) > t. A position of the luminaire 1 between the ceiling profile elements 28, in which at least one of the gaps 25 has a width S1 or S2 greater than t, can then be achieved, for example, by slightly displacing the mounted luminaire 1 in the transverse direction y.
    Of course, each of the gap widths SI, S2 could be chosen to be greater than the sheet thickness t, ie. S1 > t and S2 > t. For esthetic reasons, SI = S2 can be advantageous. This is particularly useful when, for example, due to the dimensions of components of the luminaire 1 that disappear in the grid ceiling 20 in the mounted state, the luminaire 1 does not tip over easily after releasing the snappers 13 on one of the long sides 7a or 7b. In this case, the snapper 13 are advantageously solved on both long sides 7a, 7b of the lamp 1 by means of disassembly tools 78 and then the lamp 1 is removed from the grid ceiling 20. For example, approximately SI = S2 = 1.5 mm.
    The luminaire 1 can thus be mounted in a simple manner by a designer without the aid of tools and with little time expenditure between the ceiling profile elements 28 of the grid ceiling 20. The disassembly of the lamp 1 can be done easily and quickly. The dismantling requires no kompli¬zierten handles and no screwdriver or derglei¬. Only one or more of the disassembly tools 78 are used to release the snapper 13 by a simple pull.
    Although the present invention has been fully described above with reference to preferred embodiments, it is not limited thereto, but may be modified in various manners.
    In particular, the present invention is advantageously applicable to mounting luminaires to grid ceiling profiles of widely varying cross-sectional shape, wherein, depending on the dimensions and the cross-sectional shape of the profile, the position of the snapper is adapted to the profile type relative to the other components of the luminaire when needed, for example Flush mounting of the luminaire to achieve.
    In addition, the invention is not limited to luminaires with a long-drawn basic shape. It is conceivable to apply the invention to a luminaire having, for example, a quadratic basic shape or another basic shape, wherein it would be possible to provide snap-action on more than two sides of the luminaire.
