Definitions

  • a ceiling or wall element is generally understood to mean that section of a ceiling or wall that surrounds the mounting system. Whether this is a single, connected element or a plurality of assembled elements is just as irrelevant as the construction.
  • the term ceiling or wall element includes both solid construction ceilings, for example concrete ceilings, and dry construction ceilings, for example gypsum fiber or plasterboard ceilings; the same also applies to walls.
  • Recessed lighting fixtures which are mostly located inside a ceiling or wall element, are used in buildings such as houses or in structures and supporting structures such as roofs and tunnels. Brackets or mounting systems are usually used here to securely fix the lighting fixture to or in the ceiling or wall element. Such mounting systems are preferably plastered in after installation so that a visually uniform overall appearance is created and only the lighting fixture and part of its bracket are visible from the outside.
  • the requirements for such mounting systems are diverse and sometimes contradictory: on the one hand, the required installation space, in particular the installation depth, should be as small as possible, and on the other hand, a mounting system should be flexible and usable for a wide range of applications.
  • a structure that is as simple as possible in order to reduce unit costs and assembly that is as simple and uncomplicated as possible is offset by the requirement for a high degree of adaptability to the specific circumstances.
  • cooling elements may be necessary, whose task is to dissipate the heat lost by the lighting fixtures to the environment as effectively as possible in order to keep the operating temperature of the lighting fixtures low. To achieve this, cooling elements with a large surface area are preferably used.
  • the EP 3 879 169 A1 discloses a mounting system with a carrier element, a cooling element and a mounting fixed to the cooling element in a rotationally fixed manner for receiving a light body, wherein the mounting extends in sections from an opening of the
  • the bracket has an external thread which interacts with an internal thread arranged in the opening of the support element.
  • a projection protruding from the opening also known as a plastering section, can be varied in order to be able to adapt the bracket system to different thicknesses of plaster or filler layers.
  • a locking connection is proposed.
  • a disadvantage of the state of the art is that the adaptability of the projection to different thicknesses of plaster or filler layers usually has to be done before assembly or is only possible to a limited extent when assembled: If the carrier element is held stationary and the mounting element is rotated during rotation in the assembled state, the cooling element and all electrical connections and wiring are also rotated, which is only possible to a limited extent - if at all - and allows at most a minor adjustment.
  • the bracket is held stationary and the carrier element is rotated, this results in design restrictions with regard to the shape of the carrier element: in particular, only a circular or polygonal shape is conceivable, since otherwise no rotation is possible when installed; furthermore, the carrier element cannot be connected to the ceiling or wall element in a rotationally fixed manner.
  • the projection must therefore be adjusted before assembly when the elements can still be freely rotated against each other.
  • the alternatively proposed snap-in connection only allows discrete, not continuous adjustment.
  • the mounting system is not suitable for all types of ceiling or wall elements without extensive adaptation.
  • it is only useful for ceiling or wall elements in dry construction, as the system can be hung into these and no rotationally fixed connection is required.
  • the projection is that part of the support element which protrudes from the opening of the support plate on the visible side.
  • a main dimension of the projection is measured according to the longitudinal extension between the corresponding end of the receiving extension, in particular a closing edge, and a front surface of the support element along the longitudinal axis.
  • the corresponding dimension of the projection is determined between a normal plane associated with the closing edge and a normal plane associated with the front surface.
  • An outer surface of the overhang serves as a plastering surface if, after the mounting system has been installed, a layer of plaster or filler is applied to the carrier plate and the surrounding ceiling or wall element.
  • a layer of plaster or filler is applied to the carrier plate and the surrounding ceiling or wall element.
  • the overhang must be varied so that the end of the support extension, in particular the end edge, is flush with the layer of plaster or filler.
  • the support extension and any light fixture inserted in it are therefore integrated seamlessly into the appearance.
  • the visible side, in particular the front surface, of the carrier plate is fitted into the ceiling or wall element during installation and can be fixed to it in place.
  • the variation of the projection is decoupled from the holding element and is carried out via separate and actuatable spacing means. Accordingly, a mechanical connection between the holding element and the carrier plate is not absolutely necessary, and no contact between the receiving extension and an inner wall of the bore is necessary either. Since the carrier plate is connected to the cooling element via the spacing means and the holding element is attached to the cooling element, the The projection of the receiving extension can be varied indirectly by changing the distance between the carrier plate and the cooling element using the spacing means: If the distance between the carrier plate and the cooling element is reduced using the spacing means, the projection increases because the receiving extension protrudes further over the carrier plate.
  • the projection decreases because the receiving extension is "pulled in".
  • the dimensioning of the spacing means and the receiving extension can thus be used to constructively define a maximum projection that can be exploited, with a middle ground preferably being chosen between the smallest possible installation depth and the maximum possible projection.
  • the spacing means can be operated from the visible side of the support element, i.e. from the side of the support plate that remains visible and accessible after installation in the ceiling or wall element, ensures that the overhang can be easily adjusted without restrictions even after the mounting system has already been installed. Accordingly, a mounting system according to the invention enables maximum variability even when installed, since each overhang can be adjusted between a minimum value and the maximum possible overhang.
  • spacing means A variety of different mechanical solutions can be used as spacing means, with both purely translational means, such as scissor gates, and means that translate a rotation about its own axis into a translational movement, such as elements provided with a threaded section, or combinations thereof, being conceivable.
  • the spacing means do not have to be actuated simultaneously, but can be actuated one after the other.
  • the mounting system can be mounted on a large number of different ceiling or wall elements, since corresponding fastening elements - if necessary - can be easily guided through the cooling element without this having a negative influence on the variability of the projection.
  • an axis of the opening of the carrier plate is aligned parallel, in particular coaxially, to the longitudinal axis. It is also advantageous for this purpose if the plate-shaped cooling element and the carrier plate are aligned essentially normal to the longitudinal axis. The installation depth is particularly small if both measures are taken.
  • the design of the mounting system according to the invention enables the use of large-area plate-shaped cooling elements in relation to the illuminant or to a cross-section of the receiving section of the mounting element, so that the use of luminous elements with high light outputs is possible due to the high achievable cooling performance.
  • the carrier plate preferably has a polygonal shape, although a round or elliptical shape is also conceivable. It has proven advantageous if the carrier plate has a rectangular shape and thus has a rectangular outline. It is also advantageous if the outline of the cooling plate is essentially the same as the outline of the carrier plate.
  • the carrier plate is preferably made of a material that has good adhesion properties for mineral or synthetic resin-bonded plasters or fillers. It is therefore advantageous to have the carrier plate in the form of gypsum fibreboard or plasterboard.
  • the plate-shaped cooling element is preferably made of metal, in particular as a flat cooling plate.
  • the mounting system comprises at least two spacing means, preferably exactly three spacing means.
  • the distance between the carrier plate and the cooling element can be easily adjusted even in mounting systems in which the base area of at least the carrier plate, preferably the carrier plate and the plate-shaped cooling element, is a multiple of the cross section of the receiving extension. If three spacing means are provided, the mounting system is on the one hand highly stable and on the other hand can still be operated with relatively little effort. By providing at least two spacing means, small differences in the visible surface of the ceiling or wall element can also be compensated.
  • the spacing means each comprise an actuating section mounted in the carrier plate and a threaded section, wherein the threaded section is screwed to a counter thread of the cooling element. Because the spacing means each have a threaded section, the positioning of the carrier plate and cooling element along the longitudinal axis can be achieved by a rotational movement of the spacing means about their own axis.
  • The, in particular, stationary, mounting of the actuating section in the carrier plate on the one hand ensures that the actuating section is accessible from the visible side, and on the other hand it ensures that the cooling element is moved relative to the carrier plate by the counter thread and not vice versa. Furthermore, the Bearing of the actuating section also ensures that the plate-shaped cooling element is supported on the carrier plate.
  • the spacing means are designed as screws, wherein the screw head represents the actuating portion and the screw thread represents the threaded portion.
  • the carrier plate has a bearing pocket for each spacing means, which is open both laterally and in the direction of the installation side, for the stationary mounting of the actuating section in the direction of the longitudinal axis, and each bearing pocket is accessible via an actuating opening from the visible side of the carrier plate.
  • the bearing pocket can be, for example, a groove or a milled recess in the carrier plate, which makes it possible for the actuating sections to be easily inserted into the carrier plate and held in the carrier plate.
  • Stationary mounting is to be understood as meaning that in an assembled state of the mounting system, only a rotation of the spacing means about its own axis is possible, but no translational movement in the direction of the longitudinal axis. This structurally ensures that the cooling element can be "pulled towards the carrier plate” or "pushed away from the carrier plate”.
  • the bearing pockets are also open in the direction of the installation side.
  • the actuation openings serve to be able to actuate the spacer in the assembled state, preferably using a tool such as a screwdriver.
  • the bearing pockets have, at least in sections, a trapezoidal cross-section for receiving the actuating section and are shaped accordingly, in particular in the manner of a dovetail groove.
  • the design of the Bearing pockets as T-slots are an advantageous alternative to the previously described variant.
  • the positioning of the bearing pockets can also ensure that the spacing means do not detach from the carrier plate despite the lateral opening of the bearing pockets.
  • at least two bearing pockets are arranged on opposite sides of the carrier plate for this purpose.
  • a further embodiment of the invention provides that the carrier plate has a recess in the area of the outlet opening on the installation side, wherein the recess is dimensioned such that the base section of the mounting element can be at least partially sunk into the recess due to the relative movement between the carrier plate and the cooling element. Due to the ability to sunk the mounting element, in particular its base section, into the carrier plate, the height of the base section does not have to be added to the total height, more precisely only to the extent of the non-sunken portion.
  • a collision with the installation side of the carrier plate would represent an end point for positioning during the relative movement of the cooling element with respect to the carrier plate.
  • the recess allows this end point to be moved to just above the visible side, so that only a residual section of the carrier element remains in the area of the recess, which forms the opening.
  • the dimensioning is usually achieved by making the cross-section of the recess larger than the outline of the base section in the direction of the longitudinal axis.
  • the mounting system comprises at least two fastening tabs for supporting the mounting system outside a contour of the carrier plate, wherein the fastening tabs are connected to the carrier plate and each have a tab section extending in a plane normal to the longitudinal axis, wherein the tab sections protrude beyond the contour of the carrier plate at least in sections, wherein the mounting system can be attached by means of the tab sections to a section of the ceiling or wall element that laterally surrounds the carrier plate.
  • the ceiling or wall element comprises one or more dry construction elements, for example gypsum fiberboard or plasterboard, wherein the mounting system is introduced into an installation opening in the dry construction element.
  • outline of the carrier plate is understood to mean a projection of the carrier plate onto a plane normal to the longitudinal axis.
  • the outline of the carrier plate corresponds to the base plan of the carrier plate in a coordinate system in which the longitudinal axis acts as the height direction.
  • the mounting system can be supported via the tab sections on the surrounding sections of the ceiling or wall element, in particular on the sections of a drywall element adjacent to the installation opening.
  • the connection to the carrier plate can be direct or indirect, as well as detachable or non-detachable.
  • the fastening tabs can be glued or screwed to the carrier plate, or a mechanism with retaining grooves and retaining elements, as described in detail below, can be provided.
  • the tab sections can also be used to anchor second fastening elements, such as fastening screws or nails, so that they can be driven through the ceiling or wall element from the visible side and anchored in the tab section.
  • the tab sections advantageously have a grid-like structure with a plurality of holes, at least in sections.
  • a suitable formwork body must be provided when the concrete ceiling is formed so that an installation cavity is created for the mounting system after the concrete ceiling has been poured. Due to the particularly low installation depth of the mounting system in question, which can be between 15 and 60 mm, particularly in the range of 25 +/- 5 mm, the installation cavity can be relatively small. For example, a simple board, e.g. 25 mm thick, can be cut to size as a formwork body.
  • the mounting system further comprises at least two spacers for determining an installation depth, wherein the spacers are connected to the carrier plate and each have at least two spacer elements protruding from the installation side in the direction of the longitudinal axis.
  • the spacer elements can ensure that the visible side of the carrier plate is flush with the ceiling or wall element.
  • connection of the spacers to the carrier plate is analogous to the connection of the fastening tabs described above.
  • Vario elements are designed in such a way that they can fulfill the function of both a spacer and a fastening tab, depending on how they are connected to the carrier plate.
  • the two configurations described below are possible.
  • the tab sections are "retracted", i.e. the tab sections do not protrude beyond the outline of the carrier plate and are therefore directed "inwards" and accommodated between the plate-shaped cooling element and the carrier plate. Due to this arrangement, the tab sections do not hinder the required assembly. In the assembled state, only the spacer elements are used.
  • the vario elements are designed in such a way that they can be converted from one configuration to another by rotating 180° around their own axis.
  • connection of the Vario elements to the carrier plate can be carried out analogously to the described connection of the spacers and the fastening tabs.
  • variable elements are independent of the spacing means, although the combination naturally brings synergistic advantages. Accordingly, the technical effect of the variable elements can also be achieved with a mounting system according to the preamble of claim 1 and the characterizing features of claim 7. The same applies to the claims dependent on claim 7.
  • a further embodiment of the invention which is also applicable analogously for the spacers or the fastening tabs, provides that the carrier plate has at least one laterally open retaining groove for each Vario element, each Varioelement has at least one retaining element on a lower side facing away from the spacer elements, designed to be received in the corresponding retaining groove, wherein the holding element can be inserted into the holding groove in order to hold the Vario element stationary in the direction of the longitudinal axis and wherein the holding element does not extend into the area of the tab section. Since the carrier plate has at least one holding groove for each Vario element, each Vario element preferably has a number of holding elements corresponding to the number of holding grooves.
  • the combination of a holding element and a holding groove is basically sufficient for fastening a Vario element, it is advantageous if at least two, preferably exactly two, holding elements and holding grooves are provided per Vario element.
  • the holding grooves are laterally open on opposite side surfaces of the carrier plate, in particular on those side surfaces which do not have the open bearing pockets.
  • the Vario elements can be connected in two configurations in a simple manner: Since the at least one retaining element is arranged asymmetrically with respect to the spacer elements and the tab sections - namely not below the tab sections - on the Vario element, the desired configuration can be selected by inserting the at least one retaining element sideways into the corresponding retaining groove. If the Vario element is inserted into the retaining groove with the side that has the tab section first, the first configuration is achieved. If the Vario element is rotated by 180° and inserted into the retaining groove with the other side first, the second configuration is achieved.
  • the functionality of the stationary bearing in the retaining grooves corresponds to the function of the bearing pockets described above, whereby the retaining grooves are preferably also designed as dovetail grooves.
  • the carrier plate has at least two fastening openings, wherein at least two of the spacer elements are designed as sleeve-shaped spacer elements, which sleeve-shaped spacer elements are positioned coaxially to the fastening openings, so that first fastening elements can be guided through the fastening openings and the respective sleeve-shaped spacer elements, by means of which first fastening elements the mounting system can be fastened to a section of the ceiling or wall element located behind the cooling element as seen in the direction of the longitudinal axis.

Accordingly, according to a further embodiment variant, it is provided that the cooling element covers at least 75%, preferably at least 85%, in particular at least 90%, of an outline area of the installation side of the carrier plate.

  • Each Varioelement 20 has at least two spacer elements 18 as well as a tab section 19.
  • each Varioelement 20 also has an additional sleeve-shaped spacer element 18a, which functions as an extension of a fastening opening 16 of the carrier plate 4 when the Varioelement 20 is correctly connected to the carrier plate 4.

  • Vario elements 20 A decisive advantage of the Vario elements 20 is that the mounting systems 1 with the same components can also be used for ceiling or wall elements 3 of different construction types, in particular for solid construction and dry construction, whereby only the Vario elements 20 have to be changed, in particular repositioned.
  • the mounting system 1 is shown with "folded" tab sections 19, wherein the Vario elements 20 are connected to the carrier plate 4 in such a way that the tab sections 19 do not protrude beyond an outline of the carrier plate 4 (see in particular Fig.2 and among others Fig.7 ).
  • Such a configuration is particularly suitable for use in solid construction ceiling or wall elements 3.
  • Figure 5 shows the steps that are necessary to transfer the Varioelement from the first configuration to the second configuration (see arrow illustration).
  • the corresponding Varioelement 20 is first detached from the carrier plate 4, then rotated 180° around its own axis and finally reconnected to the carrier plate 4.
  • the tab sections 19 project laterally beyond the outline of the carrier plate 4 so that the mounting system 1 can be supported outside the outline of the carrier plate 4.
  • the connection of the Vario elements 20 to the carrier plate 4 is made via retaining grooves 21, which are provided in the carrier plate 4, on the one hand, and via retaining elements 22 attached to the Vario elements 20, which can be inserted into the retaining grooves 21.
  • the retaining grooves 21 and retaining elements 22 are designed in the illustrated embodiments according to the tongue and groove principle, with the retaining grooves 21 being designed as dovetail grooves. This construction is particularly good in the Fig. 17 shown sectional view. Due to this geometric shape of the holding grooves 21 or the holding elements 22, the holding elements 22 can be held stationary and the tab sections 19 can be used for support in the second configuration.
  • the holding elements 21 are arranged on the underside 20a of the Vario elements 20 facing the carrier plate 4, i.e. on the side of the Vario elements 20 opposite the spacer elements 18, 18a. Since the holding elements 21 are arranged asymmetrically on the Vario element 20 with respect to the tab section 19 and the spacer elements 18, 18a, namely in that area of the Vario elements 20 which is not the tab section 19, it can be ensured in a simple manner that the tab sections 19 do not protrude beyond the outline of the carrier plate 4 in the first configuration when the holding elements 22 are fully inserted into the holding grooves 21.
  • Vario elements 20 can also be realized in a structurally simple manner by using retaining grooves 21 and retaining elements 22.
  • FIGS. 7 to 9 show, as previously announced, a ceiling or wall element 3 which is designed in solid construction and thus comprises a solid body 26.

  • a solid body 26 can for example, a concrete ceiling in which the installation cavity 27 is formed by a formwork body during the concrete pouring. Due to the low construction height and installation depth of the mounting system 1, the installation cavity 27 can have a relatively small depth so that, for example, steel reinforcements are not affected.
  • variable elements 20 of the mounting system 1 are brought into the first configuration before assembly, so that the tab sections 19 do not protrude beyond the outline of the carrier plate 4.
  • one of the spacing means 11 can be seen in section on the one hand and one of the variable elements 20, in particular the sleeve-shaped spacer element 18a, on the other hand.

  • the depth of the installation cavity 27 and the height of the spacer elements 18, 18a thus also make it possible to achieve an essentially flush finish between the visible side 4a of the carrier plate 4 and the ceiling or wall element 3.
  • the spacing means 11 serve to position the cooling element 6 along the longitudinal axis 10 relative to the carrier plate 4. This makes it possible to vary a projection 9a of the receiving extension 9 protruding from the carrier plate 4. While the projection 9a in Figure 8 is relatively small, the distance between the cooling element 6 and the carrier plate 4 is relatively large.
  • the actuating sections 11a of the spacing means 11 i.e. in the present embodiment by turning the screws, the cooling element 6 is moved in the direction of the carrier plate 4 by means of the interaction of the threaded sections 11b and the counter thread 12.

  • the mounting system 1 can be adapted to different thicknesses of plaster layers 31 or, if necessary, filler layers: For a thin plaster layer 31 (see Fig. 14 ), a small overhang 9a is required to ensure that the receiving extension 9 or a final edge 9b of the receiving extension 9 is flush with the plaster layer 31. On the other hand, to compensate for a correspondingly thicker plaster layer 31 (see Fig. 15 ) a larger projection 9a is required.
