Description

FIELD OF THE INVENTION

The present invention relates to a holder for attaching a lighting device or a Beleuchtungseinrichtungsaufhängeteils on a ceiling or a wall, the holder comprising a substantially cylindrical base body which extends along a longitudinal axis from a base body beginning to a base body end and having an outer circumferential surface, wherein the outer lateral surface is arranged an external thread which extends at least in sections along the longitudinal axis.

STATE OF THE ART

From the prior art mounting options for lighting devices in ceilings and / or walls are known in which the lamp sits for the most part in the interior of the ceiling / wall, more precisely in a cavity of the ceiling / wall. Here, the ceiling / wall may be formed, for example, with plasterboard, in which case relatively expensive brackets are needed to securely fix the lighting device to the plasterboard.

Furthermore, the ceiling / wall may be formed with a poured concrete layer. For this case is from the EP 3153642 A1 a mounting system with a hollow body is known which comprises a receiving opening for the lighting device.

The known solutions have, on the one hand, the disadvantage that completely different holders are necessary for the different types of ceiling / wall. On the other hand, the application of a spatula or plaster layer on the ceiling / wall can lead to problems to the effect that the respective holder is not tuned to the increased by the spatula or plaster layer thickness of the ceiling / wall. In particular, a poor hold of the holder is usually given in the spatula or plaster layer.

Finally, the Einspachteln / plastering of known brackets can make difficult, on the one hand means increased production costs and on the other hand involves the risk of optical defects.

OBJECT OF THE INVENTION

The object of the present invention is to provide a holder for fixing a lighting device or a lighting device suspension part, which avoids the disadvantages mentioned above. In particular, the holder according to the invention should be used for different ceiling / wall constructions and provide optimum support in a spatula or plaster layer. Preferably, the holder should facilitate the application of the spatula or plaster layer.

PRESENTATION OF THE INVENTION

To achieve the object mentioned, it is in a holder for attaching a lighting device or a Beleuchtungseinrichtungsaufhängeteils on a ceiling or wall, the holder comprising a substantially cylindrical base body which extends along a longitudinal axis from a base body beginning to a base body end and an outer surface , wherein on the outer lateral surface an external thread is arranged, which extends at least partially along the longitudinal axis, according to the invention provided that at least one anchor element for preventing rotation of the holder is arranged in a plaster or putty in the region of the base body end, said at least one anchor element protrudes in a first direction from the base body, wherein the first direction has at least one directional component, which direction component is in a normal plane normal to the longitudinal axis.

The male thread allows attachment of the bracket to a variety of ceiling / wall systems. For example, the holder with the base body beginning in front in a receiving opening of a hollow body of a mounting system according to the EP 3153642 A1 be screwed. Moreover, it can be adjusted by turning the bracket exactly how much the bracket projects beyond the ceiling / wall. That is, when the ceiling / wall nor a spatula or plaster layer is applied, can be achieved by turning the holder that the holder the ceiling (without plaster or filler layer) surmounted by exactly the thickness of the spatula or plaster layer. This allows a flush completion of the holder with the spatula or plaster layer, which is also associated with a good grip of the holder in the spatula or plaster layer.

"Stand out" is to be understood here and below always as pointing away from the base body or pointing outwards, unless explicitly stated otherwise.

By the at least one anchoring element projecting from the base body, it is simply plastered or plastered into this layer when applying the spatula or plaster layer. It is understood that the at least one anchor element in addition to the anti-rotation corresponding to a backup of the holder against an undesired change in position due to an axial, i. along the longitudinal axis, acting force offers.

According to the definition of the first direction, there are not exactly one possible, but in principle infinitely many possible first directions. For example, all directions pointing outwards away from the longitudinal axis and having at least one radial directional component (normal to the longitudinal axis) are possible first directions. Furthermore, all directions which are tangential to the lateral surface and have at least one directional component in the normal plane would also be possible first directions. The latter can be assumed in principle along the entire circumference of the base body on the lateral surface.

It is understood that first directions are also possible which are complete, i. with all directional components, lying in the normal plane. In this case, the respective first direction is normal to the longitudinal axis (and thus encloses this with an angle of 90 °). Typically, the angle that the first direction includes with the longitudinal axis is in a range of 80 ° to 100 °, preferably in a range of 85 ° to 95 °.

The exact geometric shape of the at least one anchor element may vary. For example, the respective anchor element in a plan view along the longitudinal direction seen to have a substantially rectangular or trapezoidal shape or a substantially triangular or semicircular shape. Accordingly, the respective anchor element may at least in sections have the shape of a cuboid or prism or a hemisphere. It would also be conceivable, for example, for the respective anchor element to have the shape of a cylinder or pin at least in sections.

In order to be able to easily connect the lighting device or the lighting device suspension part with the holder, a per se known mounting structure for the lighting device or the Beleuchtungseinrichtungsaufhängeteil is preferably formed on an inner side of the base body, in particular a projection or a step or a thread or a bayonet or Schnappverschlussteil or a magnetic closure part.

In order to enable a particularly good toothing or a particularly good hold of the holder in the plaster or filler layer, it is provided in a preferred embodiment of the holder according to the invention that a plurality of anchor elements are provided, which in the region of the base body end circumferentially, preferably with the same or Periodically equal distances from each other, are distributed over the base body. By "periodically equal" intervals is meant a case in which not all distances are the same, but a sequence of different distances of successive armature elements along the circumference (ie, in a circumferential direction) is repeated.

As mentioned, the holder according to the invention can be adapted by turning to a desired thickness of the filler or plaster layer to be produced. In addition, to allow easy to produce, perfect flush connection of the spatula or plaster layer to the holder, it is at a preferred embodiment of the holder according to the invention that a plaster or spatula edge is provided which protrudes in the region of the base body end in a second direction from the base body, wherein the second direction has at least one directional component in a longitudinal direction, which longitudinal direction is parallel to the longitudinal axis and from Base body beginning to the base body end has, and that the cleaning or spatula edge projects beyond the at least one anchor element and the base body in the longitudinal direction.

That the longitudinal direction or the corresponding directional component of the second direction points away from the base body and thus also from the ceiling / wall, when the holder is fixed in this. It is conceivable that the second direction is completely parallel to the longitudinal direction, i. that all directional components of the second direction are parallel to the longitudinal direction.

The plaster or putty edge forms a protruding defined limit to which the plaster or putty layer is applied. If plaster or putty over the plaster or spatula edge is introduced in the direction of the longitudinal axis in the space bounded by the base body of the free space, this mass can be easily scraped off the holder again. The plaster or putty edge thus allows the easy generation of a well-defined flush completion of the plaster or filler layer towards the holder.

As already noted, the holder according to the invention can be used with a hollow body of a per se known mounting system for fixing a lighting device or a Beleuchtungseinrichtungsaufhängeteils in a, preferably cast with concrete layer of a ceiling / wall. For this purpose, before pouring a formwork with the respective potting compound, in particular with liquid concrete, a positioning fixed on the formwork. The holder according to the invention is fastened to the positioning element, onto which in turn a hollow body with a receiving opening provided with an internal thread is screwed. Instead of the internal thread, of course, other known, in particular lockable, means could be provided, which can be brought into engagement with the external thread of the holder according to the invention, for example a latching element or a rack. In this way, a fixation of the hollow body results on the formwork. This is followed by pouring. After the potting compound has hardened, the formwork and the positioning element are removed.

The holder now concludes substantially flush with the cast layer and must be turned a piece from the receiving opening of the hollow body to be adapted to the desired thickness of the still to be applied plaster or filler layer. It should be noted that when applying the plaster or filler layer, the at least one anchor element is plastered / zugespachtelt and then arranged in the plaster / filler layer to act as a safeguard against changes in position of the holder, in particular as anti-rotation. If the holder has the plaster or spatula edge, the flush application of the plaster or filler layer in the area of the holder is greatly facilitated.

So that a problem-free unscrewing of the holder is possible, the anchoring elements must at least not be too strong with the potting compound in contact, otherwise the anchor elements are so intimately connected to the potting compound that they block the rotation of the holder. The latter case can be given in particular if the at least one Anchor element has been poured around from all sides with potting compound.

In order to ensure that the holder according to the invention can be rotated after casting or unscrewed from the receiving opening of the hollow body, it is provided in a preferred embodiment of the holder according to the invention that the at least one anchor element seen in a circumferential direction has at least one side surface at least one shuttering element is arranged in the region of the base body end, which, preferably by means of at least one predetermined breaking point, releasably connected to the base body and projects in a third direction from the base body, wherein the third direction has at least one lying in the normal plane direction component, and that at least a shuttering element is arranged and dimensioned so that at least one in the circumferential direction of the at least one side surface adjoining free-hold area of potting compound is kept free when the holder with the base body heend is arranged pointing to a formwork on this formwork and is poured over with the potting compound.

The connection of the at least one formwork element to the base body may be direct or indirect, i. with the interposition of at least one other element. Furthermore, the at least one formwork element may be made as a separate element, e.g. by plugging on the base body positively and / or non-positively connected to this releasably.

Under "circumferential direction", the directions in clockwise and counterclockwise direction are always subsumed here and below.

Depending on the specific geometry of the respective anchor element this may have a plurality of side surfaces in the circumferential direction. For example, in a cylindrical Anchor member which protrudes perpendicularly from the base body - ie, the first direction is normal to the longitudinal axis -, those parts of the shell, which face the circumferential direction are regarded as side surfaces, so that in this example two side surfaces would be given.

The third direction preferably coincides - but not necessarily - with the first direction. In particular, all the directional components of the third direction may lie in the normal plane, so that the third direction encloses a right angle with the longitudinal axis. Typically, the angle that the third direction includes with the longitudinal axis is in a range of 80 ° to 100 °, preferably in a range of 85 ° to 95 °.

Particularly preferably, the third direction has a directional component parallel to the longitudinal direction. That is, the third direction is oriented such that an outer edge of the respective formwork element is arranged in the longitudinal direction behind the region with which the respective shuttering element is arranged on the base body or connected thereto (preferably via the at least one predetermined breaking point). In a side view, this results in a kind of roof-shaped geometry of the at least one formwork element. This geometry allows that the holder, when it is placed on the formwork during casting, rests on the formwork with the outer edge of the at least one formwork element. Alternatively or additionally, the outer edge of the at least one formwork element may be provided with a kind of sealing lip, which closes the holder in the longitudinal direction, so as to ensure that the holder, when it is placed on the formwork during casting, with the outer edge or rests with the sealing lip of the outer edge of the at least one formwork element on the formwork. By said resting can be prevented when casting Potting compound between the at least one formwork element and the formwork passes.

The at least one clearance area does not have to connect directly to the side surface of the at least one anchor element. In particular, a narrow gap between the side surface and the clearance area can be arranged, which is dimensioned so that either no potting compound can pass or only so much that the resulting narrow strip of potting compound after curing no great resistance opposes the rotation of the holder and when twisting simply "turned off" or is broken away.

The at least one clearance area itself is kept free by the at least one shuttering element when casting potting compound and thus allows after casting the unscrewing of the holder.

In this case, the connection between the at least one anchor element and potting compound is prevented or at least weakened so much that the unscrewing / -screwing of the holder is possible by the at least one free-holding area or due to the at least one free-space. For this purpose, it may suffice, for example, that the at least one free-hold area only covers an angular range which is so great that a certain rotation, eg a quarter turn, of the holder is made possible without the at least one anchor element with its at least one side face against the hardened potting compound or a negligible potting compound with the at least one side surface can not be sheared off. The allowed rotation has to be so great that the holder has moved so far out of the ceiling in the longitudinal direction that the at least one anchor element in a further rotation in the same direction no longer cured Casting compound touched. That is, the holder can then be arbitrarily far out of the ceiling or the hollow body out.

So that the free space can fully fulfill the described function, the at least one formwork element is released and removed after curing of the potting compound and the removal of the formwork including positioning of the base body. This is preferably done by breaking off the at least one formwork element at the at least one predetermined breaking point, e.g. a screwdriver and / or a pair of pliers can be taken to the rescue.

Structurally, what has been said above preferably means that the at least one anchoring element has at least one side surface seen in a circumferential direction, that at least one formwork element is arranged in the region of the base body end, which is detachably connected to the base body, preferably by means of at least one predetermined breaking point, and in one third direction protrudes from the base body, wherein the third direction has at least one directional component lying in the normal plane, that in a longitudinal direction which is parallel to the longitudinal axis and the base body beginning to the base body end, arranged at least one shuttering element before and / or next to the at least one anchor element and that in the circumferential direction the at least one formwork element fills at least a region which is arranged behind the at least one side surface of the at least one anchor element, wherein an extension of this at least one region in the first direction is at least as large as the extension of the at least one anchor element in the first direction to at least one free to the at least one side surface Freihaltebereich of potting freed when the holder is arranged with the base body end pointing to a formwork on this formwork and is poured over with the potting compound.

As stated above, the clearance area does not necessarily have to connect directly to the side surface, but can also be arranged in the circumferential direction with the interposition of a gap behind the at least one side surface. The at least one clearance area is seen in the longitudinal direction covered by at least one shuttering element. For this purpose, the at least one formwork element is arranged in the longitudinal direction in front of and / or in the at least one free-fall area.

With yet another words it can be provided that in the region of the base body end at least one formwork element is arranged, which is preferably connected by means of at least one predetermined breaking point, releasably connected to the base body and projects in a third direction from the base body, wherein the third direction at least one in the Normal plane lying direction component, wherein seen along the longitudinal axis and the base body beginning to the base body end, the at least one formwork element conceals and / or fills at least one Freihaltebereich to indemnify the at least one Freihaltebereich of potting compound, if the holder with the base body end pointing to a formwork on this formwork is arranged and is poured over with the potting compound, wherein the anchoring element of the free-holding area or to each of the anchor elements of the free-hold areas in a circumferential direction and wherein the at least one Freihalteb extends in both the circumferential direction and in the first direction, wherein the extent of the at least one free-space in the first direction is at least as large as the extent of the at least one anchor element in the first direction.

It should be noted that it is also conceivable to use variants of the inventive holder without formwork element with the mounting system or hollow body. This is Especially possible if the holder after casting does not have to be moved out of the receiving opening by a rotation, but by an axial or purely translational movement. For example, the holder could be pulled out of the receiving opening along the longitudinal axis, if, for example, a lockable rack is provided in the hollow body or in the receiving opening for connection to the holder, the lock has been released. Even if the at least one anchor element should come into contact with the potting compound when it is cast against the longitudinal direction during casting, the connection produced thereby is usually not strong enough to prevent said translatory movement, in particular said pulling out, of the mounting.

In a particularly preferred embodiment of the holder according to the invention it is provided that a plurality of anchor elements are provided and that the at least one formwork element at least partially fills the arranged in the circumferential direction between the anchor elements Freihaltebereiche. On the one hand, this allows a problem-free unscrewing of the holder from the receiving opening of the hollow body after casting. On the other hand, the plurality of anchor elements ensures a perfect grip in the plaster or filler layer.

As already described above, the at least one formwork element is preferably designed so that when casting no potting compound between the at least one formwork element and the formwork can come. Accordingly, it is provided in a particularly preferred embodiment of the holder according to the invention, that the at least one formwork element projects beyond the at least one anchor element in the first direction and that the at least one formwork element in a longitudinal direction, which is parallel to the longitudinal axis and from the base body beginning to the base body end points, the bracket is completed. The "completion" by the at least one formwork element does not exclude that there may also be points of other elements of the holder, which complete the holder in the longitudinal direction together with the at least one formwork element. For example, this may apply to the putty edge. In any case, in this embodiment there is no other element of the holder which projects beyond the at least one formwork element in the longitudinal direction. In other words, the at least one formwork element edges the holder in the longitudinal direction.

In order to enable a particularly easy unscrewing of the holder after casting, it is provided in a particularly preferred embodiment of the holder according to the invention that the at least one formwork element surrounding the base body, preferably annular, circumferentially. Accordingly, at least one clearance area is created, which surrounds the base body circumferentially. The contour or cross-section of the at least one shuttering element in the normal plane need not be annular, but could e.g. also be square or rectangular. Of course, in the said cross-section, a recess for the base body must be present.

According to the above statements, the at least one anchor element can come into contact with the potting compound with a top facing the longitudinal direction when casting, wherein the resulting connection between the potting compound and the at least one anchor element is usually not sufficient to twist or unscrew to prevent the holder after casting. However, said connection may make it difficult to turn or unscrew. In a particularly preferred embodiment of the holder according to the invention is therefore provided that viewed in a longitudinal direction which is parallel to the longitudinal axis and from the base body beginning to the base body end, the at least one formwork element completely covers the at least one anchor element.

Preferably, the at least one formwork element acts like a hood for the at least one anchor element and protects the latter from any contact with the potting compound.

In particular, a contacting of the upper side of the at least one anchor element is excluded with the potting compound in this way.

In a particularly preferred embodiment of the holder according to the invention it is provided that the at least one formwork element, preferably by means of at least one predetermined breaking point, with the at least one anchor element is detachably connected and preferably forms with this a substantially closed surface. This embodiment enables a particularly simple separation or a particularly simple breaking off of the at least one shuttering element after casting. In the at least one formwork element remains after the separation at least a cutout corresponding to the at least one anchor element.

By a "substantially closed surface" is meant a surface which is impermeable to the potting compound, especially concrete, but e.g. can be permeable to air.

Such a substantially closed surface can also be formed by the at least one formwork element and the at least one anchor element if the at least one formwork element is not connected at all directly (but only via the base body) to the at least one anchor element. This can facilitate the release or breaking off of the at least one formwork element, in particular after casting. Therefore, it is at a preferred Embodiment of the holder according to the invention provided that the at least one anchor element is arranged in at least one recess of the at least one shuttering element so that the at least one anchor element is separated from the at least one shuttering element by a respective gap. Preferably, the at least one formwork element surrounds the at least one anchor element not only in the circumferential direction, but also in the first direction.

Typically, a width of the at least one gap 0.1 mm to 0.2 mm, so that when casting no potting compound, in particular no liquid concrete, can penetrate through the gap.

It should be noted that it may also be possible in this embodiment that a certain negligible amount of potting compound passes through the resulting at least one gap between the at least one anchor element and the at least one formwork element during casting. Such a negligible proportion would be e.g. then given if after curing a kind of thin web of potting compound remains, which bridge can not prevent unscrewing the holder, but is simply sheared off when unscrewing.

In a preferred embodiment of the holder according to the invention it is provided that the holder made of plastic or metal, preferably as an injection molded part (made of said materials), is made, under metal not only pure metals, but also metal alloys such as aluminum alloys are to be understood. On the one hand, this makes possible a particularly cost-effective production. On the other hand can be avoided or at least greatly reduced by the plastic adhesion of potting and / or putty or plaster. Furthermore, the Holder be made stable enough, in particular hard enough to cut with the external thread an internal thread in a plasterboard or gypsum fiber board when the holder is screwed into a correspondingly sized hole of the plasterboard or gypsum fiber board. The latter allows a particularly simple attachment of the holder according to the invention in a ceiling / wall with the plasterboard or gypsum fiber board.

As can be seen from the above explanations, the holder according to the invention can be used in a variety of ceiling / wall constructions. According to the above, therefore, a ceiling or wall according to the invention is provided, comprising a holder according to the invention and a plate, in particular gypsum board or gypsum fiber board, wherein the holder is arranged in a hole of the plate and held by a screw or adhesive connection and in the hole, and preferably the at least one anchor element is arranged in a spatula layer or plaster layer applied to the plate, and wherein a thickness of the filler layer or plaster layer substantially corresponds to a distance measured along the longitudinal axis between the plate and a plaster or spatula edge of the holder. As a plate, e.g. Also a wooden plate or a wooden board in question.

Preferably, behind the plate, i. On a side of the plate opposite the at least one anchor element, a cavity is provided at least directly after the hole to facilitate the mounting of the holder.

The adhesive bond could, for example, by means of an adhesive by direct bonding of the holder with a hole bounding the inner surface, wherein the external thread ensures a particularly good adhesion of the adhesive to the holder.

Said screw can be realized in many different ways. Analogous to the above, in a preferred embodiment of the invention, the ceiling or wall is provided that the plate is a gypsum board or gypsum fiber board and that the holder is screwed with its external thread directly into the plasterboard or gypsum fiber board, wherein a hole bounding the inner surface at least in sections the external thread is cut. That by the rotational movement of the holder, a complementary to the external thread of the holder internal thread is generated or cut in the plasterboard or gypsum fiber board. This causes a particularly simple, rapid and cost-effective production, since only a suitably dimensioned hole in the plasterboard or gypsum fiber board must be cut or drilled before mounting the bracket.

In a preferred embodiment of the blanket or wall according to the invention it is provided that the holder is held in the hole by means of a nut engaged with the external thread, wherein preferably the nut has a larger diameter than the hole and the plate between the nut and the at least one Anchor element is arranged. The mother can in particular fixed before obstruction of the plate on a back of the plate, for example, be glued. It would, however, be e.g. also conceivable that the mother attached in the hole, for example, glued, is. Moreover, it is also conceivable that the holder is arranged in the hole and is countered or tightened with the mother on the back of the plate before the plate is installed, so that the mother does not need to be extra fixed or glued to the back of the plate ,

In a preferred embodiment of the ceiling or wall according to the invention it is provided that the holder is arranged in a recess of a filling body and by means of a Screw connection or adhesive bond and is held in the recess that the filler body extends at least with a holding portion in a direction having a width which is greater than a width of the hole, wherein the holding portion extends normally in this direction with a length which is at most corresponds to a length of the hole, and seen in a normal to the longitudinal axis and facing away from the direction of the plate between the holding portion and the at least one anchor element is arranged.

Preferably, the holder is first secured in the packing. If the filling body comprises a plasterboard and / or gypsum fiber board and the recess is arranged in this plate, the screw connection, with which the holder is held, e.g. take place by means of an internal thread in an inner surface delimiting the recess, wherein the internal thread is cut by the holder itself or by its external thread when screwing the holder into the recess.

But the screw can also be done for example by means of a nut which is fixed in the recess (eg glued) or larger than at least a portion of the recess dimensioned and disposed behind this section, in the latter case, the filler at least partially between the mother and the at least one anchor element of the holder is arranged.

The holder can also be glued easily by means of a known adhesive with the filler, wherein the holder is arranged in the recess of the filling body. Again, the external thread ensures a particularly good adhesion of the adhesive to the holder.

Said dimensioning of the packing in relation to the hole allows in any case the assembly of the packing the plate by turning and / or tilting the filler so that at least the holding portion can be completely inserted through the hole into the cavity behind, whereupon the filler is tilted and / or rotated in the opposite direction and not in that orientation more can be moved back through the hole. Preferably, the filler is then arranged in sections in the hole itself, in any case, the holder is at least partially disposed in the hole.

Possibly. The filler can then be bolted to the plate. As an alternative or in addition to this screw connection, it would also be conceivable to bond the filling body to the plate.

As already described in detail above, the holder can also be used for fastening a lighting device or a lighting device suspension part to a ceiling / wall with a layer of a hardened potting compound, in particular with a concrete layer. Accordingly, a ceiling or wall according to the invention is provided, comprising a holder according to the invention and in a Vergussmasseschicht, preferably concrete layer, poured hollow body, wherein the holder is screwed into a receiving opening of the hollow body and preferably wherein the at least one anchor element in a layer applied to the concrete layer of filler or Plaster layer is arranged.

As already described above in detail, after the preparation (and curing) of Vergussmasseschicht can be accurately adjusted by turning the holder from the receiving opening of the hollow body, by which distance the holder, in particular the plaster or spatula edge of the holder, the Vergussmasseschicht in Overhung in the longitudinal direction.

Accordingly, then easily a plaster or filler layer can be applied, whose thickness corresponds exactly to the said distance. Accordingly, it is provided in a preferred embodiment of the blanket or wall according to the invention that a thickness of the filler layer or plaster layer substantially corresponds to a distance measured along the longitudinal axis between the Vergussmasseschicht and the plaster or filler edge.

WAYS FOR CARRYING OUT THE INVENTION

Fig. 1 shows a holder 1 according to the invention for attaching a lighting device or a Beleuchtungseinrichtungsaufhängeteils 2 on a ceiling 3 or a wall. The holder 1 comprises a substantially cylindrical base body 7, which extends along a longitudinal axis 8 in a longitudinal direction 52 from a base body beginning 9 to a base body end 10. The base body 7 has an outer circumferential surface 11, on which an external thread 12 is arranged, which is at least extends in sections along the longitudinal axis 8 and can be used to fix the holder 1 in the ceiling 3 or wall. In the side view of Fig. 2b It can be seen that in the illustrated embodiment, the external thread 12 does not fill the entire lateral surface 11, so that a (from the external thread 12) free region of the lateral surface 11 between the external thread 12 and the base body end 10 results.

In order to be able to easily connect the lighting device or the lighting device suspension part 2 to the bracket 1, a per se known fixing structure 17 for the lighting device or the lighting device suspension part 2 is preferably formed on an inner side of the base body 7. In the embodiments of the Fig. 1 and Fig. 2a to 2d For example, the attachment structure is formed by two opposing protrusions that can be engaged with a complementary groove 26 of the illumination device or the illumination device suspension part 2, cf. Fig. 3 , As a result, a connection between the holder 1 and the lighting device or the Beleuchtungseinrichtungsaufhängeteil 2 is created in the manner of a bayonet closure.

In the region of the base body end 10, at least one anchor element 13 is arranged to prevent rotation of the holder 1 in a plaster or putty, wherein the at least one anchor element 13 protrudes in a first direction 15 from the base body 7, that points away from the base body 7. In this case, the first direction 15 has at least one direction component, which direction component is in a normal plane 48, which is normal to the longitudinal axis 8 (cf., for example, FIG Fig. 2b ) lies.

In the illustrated embodiment of the Fig. 1 (but also the FIGS. 2a-d ) four anchor elements 13 are provided, which are arranged distributed in the region of the base body end 10 along the circumference of the base body 7 and in a circumferential direction 20 at equal distances from each other over the base body 7 to a particularly good grip of the holder 1 in a plaster layer fifth (cf., eg Fig. 12 ) or putty layer 21 (cf., for example Fig. 4 ). Each of the anchoring elements 13 projects in a first direction 15, wherein the first directions 15 lie substantially completely, ie, except for possible slight deviations, in the normal plane 48 or stand normally on the longitudinal axis 8.

The exact geometric shape and the exact number of anchor elements 13 may vary. The four anchor elements 13 in the embodiments of the Fig. 1 and Fig. 2a to 2d taper slightly along the first directions 15. Viewed along the longitudinal direction 52, the anchor elements have a shape that resembles a trapezoid, cf. Fig. 2c ,

For an exemplary illustration of another possible shape and a further possible number of anchor elements 13 shows Fig. 16 in a supervision similar to Fig. 2c schematically an embodiment of the holder 1 according to the invention with three anchor elements 13, which are arranged approximately uniformly or at equal distances from each other along the circumferential direction 20 on the base body 7. Seen in the longitudinal direction 52, the anchor elements 13 have a substantially triangular shape. Furthermore is in Fig. 16 a fastening structure 17 can be seen, which is similar to the embodiment of the Fig. 1 and the FIGS. 2a-2d is formed as a projection which can be brought into engagement with the complementary groove 26 of the lighting device or the Beleuchtungseinrichtungsaufhängeteils 2.

For an exemplary illustration of another possible shape and a further possible number of anchor elements 13 shows Fig. 17 in a supervision similar to Fig. 16 schematically an embodiment variant of the holder 1 according to the invention with five anchor elements 13, which are arranged approximately uniformly or at equal distances from each other along the circumferential direction 20 on the base body 7. Seen in the longitudinal direction 52, the anchor elements 13 have a substantially semicircular shape. Furthermore, it is also in Fig. 17 a fastening structure 17 can be seen, which as in the embodiment of Fig. 16 is formed as a projection which can be brought into engagement with the complementary groove 26 of the lighting device or the Beleuchtungseinrichtungsaufhängeteils 2.

For an exemplary illustration of another possible shape and a further possible number of anchor elements 13 shows Fig. 18a in a supervision similar to Fig. 16 schematically an embodiment of the holder 1 according to the invention with two anchor elements 13, which are arranged opposite one another or at equal distances from each other along the circumferential direction 20 on the base body 7. The anchor elements 13 are designed as substantially pin-shaped or cylindrical pins. Seen in the longitudinal direction 52 thus results in a substantially rectangular shape of the anchor elements 13. It is also in Fig. 18a a fastening structure 17 can be seen, which as in the embodiment of Fig. 16 is formed as a projection which can be brought into engagement with the complementary groove 26 of the lighting device or the Beleuchtungseinrichtungsaufhängeteils 2.

The external thread 12 can, as I said, be used to attach the holder 1 in the ceiling 3 or wall. In this case, the external thread 12 also allows that can be adjusted by simply turning the holder 1, by how much the holder 1 in the longitudinal direction 52, the ceiling 3 or wall surmounted, ie, how large a distance 52 measured in the longitudinal direction of an outermost point or conclusion of the holder 1 to the ceiling 3 or wall, in which the holder 1 is mounted, is. Accordingly, the holder 1 can be exactly as far out of the ceiling 3 or wall unscrewed until said distance corresponds to a desired thickness 40, 41 an applied leveling layer 21 or plaster layer 5.

Moreover, in order to enable a simply produced, perfect flush connection of the filler layer 21 or plaster layer 5 to the holder 1, this has a plaster or spatula edge 14 in the illustrated embodiments. This cleaning or filling edge 14 projects in the region of the base body end 10 in a second direction 16 from the base body 7, wherein the second direction 16 has at least one directional component in the longitudinal direction 52. In the illustrated embodiments, the second direction 16 coincides with the longitudinal direction 52, i. all the directional components of the second direction 16 are parallel to the longitudinal direction 52. The cleaning or filling edge 14 forms seen in the longitudinal direction 52 the conclusion of the holder 1 and correspondingly projects beyond the at least one anchor element 13 and the base body 7 in the longitudinal direction 52. The plaster or filler edge 14 thus forms a projected defined limitation of the holder 1, to which the plaster layer 5 or filler layer 21 is applied. If plaster or filler is introduced beyond the cleaning or filling edge 14 in the direction of the longitudinal axis 8 in the space bounded by the base body 7 of the holder 1 free space, this mass can be scraped easily from the holder 1 again. That the plaster or filler edge 14 allows the easy generation of a well-defined flush completion of the plaster layer 5 or filler layer 21 to the bracket 1 out.

The holder 1 according to the invention is preferably made of plastic or metal or a metal alloy, in particular an aluminum alloy, which, inter alia, prevents or at least greatly reduces the adhesion of putty or plaster compound and thus assists the simple production of a flush finish of plaster layer 5 or putty layer 21 towards the mount 1. Moreover, it can be ensured by said choice of material that the holder 1 is made stable or hard enough to cut with the external thread 12 an internal thread in a plasterboard 4 or gypsum fiber board, when the holder 1 in a correspondingly sized hole 27 of the plasterboard 4th or gypsum fiber board is screwed. The latter allows a particularly simple attachment of the holder 1 according to the invention in a ceiling 3 or wall with the plasterboard 4 or gypsum fiber board.

Fig. 19 shows such a manner in a ceiling 3 with a plasterboard 4 mounted bracket 1 together in the holder 1 mounted Beleuchtungseinrichtungsaufhängeteil 2. The plasterboard 4 is fixed in a conventional manner to at least one metal profile support 22 by means of screws 23. Behind the plasterboard 4, ie on that side of the plasterboard 4, on which also the at least one metal profile support 22 is arranged, a cavity 55 is correspondingly formed. In this cavity 55, the screwed into the plasterboard 4 bracket 1 can protrude with the base body beginning 9. Furthermore, 55 electrical lines for powering the illumination device can be performed in the cavity, which electrical lines can be electrically connected to a held by the Beleuchtungseinrichtungsaufhängeteil 2 cable 25 of the lighting device in a conventional manner.

The hole 27 has a diameter 28 (see. Fig. 3 ) having a track smaller than an outer diameter 39 (see FIG. Fig. 3 ) of the base body 7 and the external thread 12 is. Now, when the holder is screwed into the hole 27, that cuts External thread 12 in the hole 27 delimiting inner surface 29 has an internal thread which is in engagement with the external thread 12 and together with external thread 12 is a screw through which the holder 1 is held in the hole 27.

As already stated, the holder 1 is screwed into the hole 27 until the distance between the plaster or spatula edge 14 and the plasterboard 4 of the desired thickness 40 of the applied filler layer 21 corresponds. Then, the filler layer 21 is applied, whereby the anchor elements 13 are introduced into the filler layer 21 and after curing of the filler layer 21, the holder 1 against changes in position, in particular against rotation, secure.

Finally, the lighting device suspension part 2 can be fixed in the bracket 1 by means of the fastening structure 17 and the groove 26.

Another way to hold the bracket 1 in the hole 27 by means of a screw connection is to provide a nut 24 with which the external thread 12 is brought into engagement. It would be conceivable, for example, to fix the nut 24 in the hole 27, for example, to glue. An alternative variant is in FIG. 3 and FIG. 4 shown. The diameter 28 of the hole 27 is here larger than the outer diameter 39 of the external thread 12, so that the holder 1 can be easily inserted into the hole 27. In the cavity 55, the nut 24 is located just behind the hole 27. The nut 24 can this particular before obstruction of the plasterboard 4 (but after creation of the hole 27) on a back of the plasterboard 4 - that is fixed on the side of the plasterboard 4, which faces the cavity 55 after the installation - fixed, for example, glued , The nut 24 has a larger diameter than the hole 27 and therefore fits not through the hole 27, so that the nut 24 is held at least form-fitting manner on the plasterboard 4. The bracket 1 is performed for mounting on the plasterboard 4 through the hole 27 and screwed to the nut 24 and screwed into the nut 24 - according to the desired thickness 40 of the applied filler layer 21st

As an alternative to the above-described assembly, the holder 1 can be arranged in the hole 27 and tightened or tightened with the nut 24 on the back of the plasterboard 4 before the plasterboard 4 is installed, so that the nut 24 is not fixed separately on the back of the plasterboard 4 or needs to be glued.

It follows in both cases described an arrangement of the plasterboard 4 between the anchor elements 13 and the nut 24th

Subsequently, the filler layer 21 is applied with the desired thickness 40, whereby a perfect flush connection of the filler layer 21 to the holder 1 can be easily ensured by the cleaning or filling edge 14. Finally, in turn, the lighting device suspension part 2 can be fixed in the bracket 1 by means of the fastening structure 17 and the groove 26, which is shown in FIG Fig. 4 is indicated by dashed lines.

Another way to hold the holder 1 in the hole 27, preferably by means of a screw, is in FIGS. 14 and 15 shown. The holder 1 is first arranged in a recess 47 of a filling body 42 and held in the recess 47 by means of a screw or adhesive connection.

In the illustrated embodiment, the filler 42 is composed of an upper part 43 and a lower part 44, wherein the upper part 43 and the lower part 44 each consist of a Plasterboard or gypsum fiber board are formed and have superimposed recesses or cutouts, which in turn form the recess 47 of the filling body 42.

Furthermore, in the illustrated embodiment, a screw connection is provided by means of a nut 24, wherein the diameter of the nut 24 is greater than the diameter of the recess 47 in the lower part 44 and as the diameter of the recess 47 in a subsequent to the lower part 44 first portion 56 of the upper part 43rd At this first portion 56 of the upper part 43, however, includes a second portion 57 of the upper part 43, in which the diameter of the recess 47 is greater than the diameter of the nut 24. The nut 24 is arranged in the recess 47 so that they the first portion 56 rests, wherein the holder 1 is screwed with the external thread 12 in the nut 24 so far that the plaster or spatula edge 14 extends beyond the lower part 44 in the longitudinal direction 52 as it corresponds to the desired thickness 40 of the applied filler layer 21.

The filler 42 is then arranged in sections between the anchor elements 13 and the nut 24. More precisely, the lower part 44 is arranged completely between the anchor elements 13 and the nut 24, and the upper part 43 only with its first section 56.

However, the holder 1 could, for example, also be glued to the filler body 42 simply by means of an adhesive known per se, the holder 1 being arranged in the recess 47 of the filler body 42.

The top 43 of the filler 42 is a holding portion that extends in a direction having a maximum packing width 46 that is greater than a width 45 of the hole 27. Normal to this direction, the top 43 extends with a length that is less than or equal to a length of the hole 27 is. This dimensioning allows the threading of the filler 42 through the hole 27, as in Fig. 14 is illustrated by the dashed lines outlines of the filling body 42 and by the associated arrows. In this case, the filler 42 is initially rotated or tilted from an initial orientation, in which the upper part 43 is arranged substantially parallel to the plasterboard 4, that the filler 42 can be completely inserted through the hole 27 in the underlying cavity 55. Thereafter, the filler 42 is brought back by tilting or rotating in the opposite direction in the initial orientation, in which the filler 42 can not be moved through the hole 27 back. By lowering the filler 42 is arranged in sections in the hole 27 itself, wherein the lower part 44 has a length and a width which are the highest as long as the length and width 45 of the hole 27.

Possibly. the filler 42 can then be screwed to the plasterboard 4 by means of screws 23. As a result, in any case, the holder 1 is at least partially arranged in the hole, as in Fig. 15 can be seen.

Subsequently, the filler layer 21 is applied with the desired thickness 40, whereby a perfect flush connection of the filler layer 21 to the holder 1 can be easily ensured by the cleaning or filling edge 14. Finally, in turn, the lighting device suspension part 2 can be fixed in the bracket 1 by means of the fastening structure 17 and the groove 26, which is shown in FIG Fig. 15 is indicated by dashed lines.

The external thread 12 of the holder 1 according to the invention further allows the attachment of the holder 1 to a ceiling 3 or wall, a cast layer, preferably a concrete layer 6, and a built-in system according to the EP 3153642 A1 having. The FIGS. 5 to 13 illustrate the individual steps of producing a corresponding cover 3 using a holder 1 according to the invention, which preferably has at least one formwork element 18, which, for example, in Fig. 2a is shown.

As in Fig. 5 shown, before pouring a formwork 38 with the respective potting compound, in particular with liquid concrete, a positioning member 36 on the formwork 38, which essentially comprises at least one plate-shaped element or board fixed. The fixation is done for example by means of a nail 37th

On the positioning element 36, the holder 1 according to the invention is now attached. For this purpose, the positioning element 36 in the embodiment shown hooks 58 which are brought into engagement with the mounting structure 17 when the holder 1 is slid along its longitudinal axis 8 on the positioning member 36, which in Fig. 5 indicated by the arrow. To prevent unwanted removal or release of the holder 1 from the positioning element 36, pin-shaped blocking elements 51 are introduced from above into the positioning element 36, which prevent springing back of the hooks 58, so that the hooks 58 at least one undesirably large, preferably any, movement of Fixing structure 17 and thus the holder 1 along the longitudinal axis 8 and the formwork 38 away form-fitting block.

Then, a hollow body 30 of the mounting system is screwed with a female thread having a receiving opening 34 on the holder 1 and on the external thread 12 thereof. The holder 1 is then located with the base body beginning 9 in the receiving opening 34. In this way, a fixation of the hollow body 30 results on the formwork 38. The hollow body 30 has in the illustrated embodiment, a lower part 32, in which the receiving opening 34 is arranged. On the lower part 32 also feet 35 are arranged, with which the lower part 32 and the hollow body 30 is supported on the formwork 38. That is, the lower part 32 can be screwed onto the holder 1 until the feet 35 touch down on the formwork 38.

Furthermore, the hollow body 30 comprises an upper part 31, which can be detachably connected to the lower part 32 in a manner known per se, e.g. by screwing or a snap lock. The top 31 may be e.g. only after the complete screwing of the lower part 32 with the holder 1 with the lower part 32 are connected.

From the upper part 31, at least one tube 33 leads away, through which electrical lines (not shown) can be guided into the hollow body 30.

Fig. 6 shows the thus positioned on the formwork 38 hollow body 30th

This is followed by the pouring out or the production of the concrete layer 6, cf. Fig. 7 ,

After the concrete layer 6 has cured, the formwork 38 and the positioning element 36 are removed, cf. Fig. 8 ,

The holder 1 now closes substantially flush with the concrete layer 6 and has to be turned part way out of the receiving opening 34 (see arrows in FIG Fig. 10 ), to the desired thickness 41 of the still applied plaster layer 5 (see. Fig. 12 ) to be adapted. When applying the plaster layer 5, the anchor element 13 are plastered and are then arranged in the plaster layer 5 in order to act as a safeguard against changes in position of the holder 1, in particular as anti-rotation. Analogous to the above, the plaster or spatula edge 14 makes it easier flush application of the plaster layer 5 in the area of the holder 1 clearly.

So that a problem-free unscrewing of the holder 1 from the receiving opening 34 is possible, the anchoring elements 13 may at least not too strong with the concrete layer 6 are in contact, otherwise the anchor elements 13 are so intimately connected to the concrete layer 6, that they rotate the holder. 1 To block. The latter case would be given in particular if the anchoring element 13 would have been poured around from all sides with concrete.

To ensure that the holder 1 can be rotated after casting or rotated out of the receiving opening 34, the at least one formwork element 18 is provided, wherein the holder 1 in the embodiment of FIGS. 2a to 13 has exactly one formwork element 18.

In all embodiments shown in which a shuttering element 18 is provided, the at least one shuttering element 18 is detachably connected to the base body 7 via at least one predetermined breaking point.

In addition, the at least one formwork element 18 in any case projects from the base body 7 in the region of the base body end 10 in a third direction 49, wherein the third direction 49 has at least one directional component lying in the normal plane 48. In the exemplary embodiments illustrated, the third direction 49 (like the first direction 15) lies substantially completely in the normal plane 48, cf. eg Fig. 2b ,

Seen in the circumferential direction 20, each anchor element 14 has at least one side surface 53. The arrangement and dimensioning of the at least one formwork element 18 is now such that at least one subsequent to the at least one side surface 53 in the circumferential direction 20 Free space 19 is kept free of the potting or concrete mass when the holder 1 is arranged with the base body end 10 facing 38 on the formwork 38 and is poured over with the potting / concrete mass (see. Fig. 6 and Fig. 7 ). In other words, the at least one shuttering element 18, as seen in the longitudinal direction 52, conceals the at least one free-space area 19 and / or fills it. In Fig. 2a four free holding areas 19 are provided corresponding to the four anchor elements 13 or covered or filled by the formwork element 18, wherein the free-hold areas 19 are indicated by the dotted arrows.

As in Fig. 2a can be seen, do not close the free areas 19 directly to the side surfaces 53 of the anchor elements 13, but there are narrow gaps between the side surfaces 53 and the hold-19 are arranged. However, in the exemplary embodiment shown, these gaps are so narrow that no concrete can penetrate through the gaps when casting concrete. For the sake of good order, it should be noted that, of course, variants of embodiment are also possible which manage entirely without gaps between the free-space regions 19 and the anchor elements 13.

In the illustrated embodiment of the Fig. 2a surrounds the formwork element 18 all anchor elements 13 and the base body 7 circumferentially or annularly, wherein the anchor elements 13 in recesses 54 (see Fig. 2c ) of the formwork element 18 are arranged. Accordingly, the formwork element 18 closes off the holder 1 in the third direction 49. In the sectional view of Fig. 2d In addition, it can be seen that the formwork element 18 also closes the holder 1 in the longitudinal direction 52 or that the cleaning or filling edge 14 in any case does not project beyond the formwork element 18 in the longitudinal direction 52.

This has the consequence that in the above-described production of the ceiling 3, the holder 1 can be mounted on the positioning member 36 so that the formwork element 18 rests on the formwork 38. Consequently, it is excluded that when pouring potting compound or concrete mass between the formwork 38 and the formwork element 18 (and thus also in the free areas 19) can get. By the free areas 19 are kept free in this way when casting potting compound or concrete mass, the problem-free unscrewing of the holder 1 is ensured from the exception opening 34 after potting. Potting compound or concrete, which adheres to a pointing against the longitudinal direction 52 top of the anchor elements 13 to this, experience can not generate a solid connection of the concrete layer 6 to the anchor elements 13, which would be strong enough to prevent the unscrewing of the holder 1.

Such a situation after casting is particularly in the detailed view of Fig. 9 clearly visible. It can be seen that the anchor elements 13 are contacted on their upper side sections of the concrete layer 6. Between the formwork element 18 and the formwork 38, however, no concrete has been able to penetrate during casting, which is why a pointing in the longitudinal direction 52 bottom of the anchor elements 13 is free of concrete.

After curing of the concrete layer 6 and the removal of the formwork 38 together with the positioning element 36, the formwork element 18 is released by breaking off the base body 7 and removed. For canceling a tool, such as a pair of pliers 50 (see. Fig. 11 ). Then, the rotation or unscrewing of the holder 1 from the receiving opening 34 can be done easily.

After the already mentioned application of the plaster layer 5 (see. Fig. 12 ), the lighting device suspension part 2 may be in the holder 1 are fastened by means of the fastening structure 17 and the groove 26, cf. Fig. 13 ,

As explained above, the connection between the at least one anchor element 13 and potting compound is prevented or at least weakened so much by the at least one free-hold region 19 or due to the at least one free-hold region 19 that the unscrewing / screwing of the holder 1 out of the receiving opening 34 is possible , For this purpose it may e.g. suffice that the at least one clearance area 19 covers only an angular range which is so large that a certain rotation, e.g. a quarter turn, the holder 1 is made possible without the at least one anchor element 13 with its at least one side surface 53 abuts against the cured potting compound or concrete layer 6 or a negligible potting compound or concrete layer 6 with the at least one side surface 53 are not sheared off can. The allowable rotation only has to be so great that the holder 1 has moved as far out of the ceiling 3 or out of the receiving opening 34 in the longitudinal direction 52 that the at least one anchor element 13 is no longer cured in a further rotation in the same direction of rotation Potting compound or concrete layer 6 touched. That the holder 1 can then be arbitrarily far from the ceiling 3 and the hollow body 30 are rotated out.

An example of this is in Fig. 18a and Fig. 18b shown. At each of the two anchor elements 13 includes in the circumferential direction 20 each with a small distance or gap a clearance 19 (indicated by dotted arrows), which covers only about a quarter turn corresponding angular range, the corresponding axis of rotation formed by the longitudinal axis 8 is. Each of these free areas 19 is covered by a formwork element 18, that is, there are two in this embodiment Shuttering elements 18 are provided. In this way it is ensured that after the casting and curing of the concrete layer 6, the removal of the formwork 38 and the positioning member 36 and after removal of the shuttering elements 38 by breaking the holder 1 at least a quarter turn can be rotated to move out of the receiving opening 34 to become. The holder 1 is thereby moved in the longitudinal direction 52 over a distance which is greater than or equal to the extension of the anchor elements 13 - and preferably also the formwork elements 18 - in the longitudinal direction 52. After the quarter turn, there is no contact of the anchoring elements 13 with the concrete layer 6, so that the holder 1 can be further rotated out of the receiving opening 34 or the ceiling 3 in the same direction of rotation.

As Fig. 18b illustrates, it may be sufficient in the dimensioning of the formwork element 18 (and thus the free-space areas 19), if they extend in the first direction 15 only as far as the anchor elements 13. In this way, abutment of the side surfaces 53 of the anchoring elements 13 on the concrete layer 6 when unscrewing the holder 1 is prevented. A larger extension of the at least one formwork element 18 in the first direction 15 but, as in the exemplary embodiment of Fig. 2a is shown, of course, possible.
