Description

FIELD OF THE INVENTION

The present invention relates to a holder for attaching a luminous element to a ceiling element or to a wall element, comprising a substantially cylindrical base body which extends along a longitudinal axis from a base body start to a base body end and has an outer surface, an element on the outer surface is arranged for adjustable fixing in the direction of the longitudinal axis, in particular an external thread, with at least one spatula element being arranged in the area of the base body end, which spatula element protrudes from the base body in a first direction, the first direction having at least one directional component, which directional component is normal lies on the normal plane standing on the longitudinal axis.

STATE OF THE ART

Recessed luminaires, which for the most part sit inside a ceiling or wall element, are used in buildings, such as houses, or in structures and structures, such as canopies and tunnels. In this case, brackets are usually used that securely fix the luminous element on the ceiling or wall element.

the end EP 3 434 964 A1 For example, a holder for attaching a luminous element to a ceiling or wall element is known, which can be used with different ceiling or wall constructions and offers an optimal hold in a putty or plaster layer. In EP 3 434 964 A1 however, it is neither described nor is there any indication of whether and how the luminous bodies may be cooled.

Depending on the luminous element, cooling elements may be necessary, which have the task of dissipating the heat loss from the luminous element as well as possible to the environment in order to keep the operating temperature of the luminous element low. To achieve this, cooling elements that have a large surface are preferably used.

For example disclosed EP 3 428 509 A1 a holder for mounting an electrical assembly, in particular a luminous element, on a ceiling or wall element. In addition to the luminous element, the electrical assembly includes, among other things, a cooling element for cooling a supply board.

A disadvantage of the holder known from the prior art is that only luminous bodies that are directly connected to a cooling element can be built into it. This means that when the luminous element is replaced, not only the luminous element but also the cooling element connected to the luminous element must be removed from the holder. In order for this to be possible, the diameter of the cooling element must not be larger than the diameter of the luminous element. In order to nevertheless enable sufficient cooling, the cooling element must therefore have a corresponding height. As a result, the mounting depth of the bracket is great.

Furthermore is at EP 3 428 509 A1 it is disadvantageous that the holder can only be adapted to a limited extent to the thickness of a layer of filler or plaster applied to the ceiling or wall element.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide a holder for fastening a luminous element which overcomes the disadvantages of the prior art and does not lead to overheating of the luminous element despite a low installation depth, small luminous opening and good maintainability. In addition, the bracket should be attached to the wall or ceiling flush mounting of the luminous element a thickness of a filler layer or plaster layer applied to a ceiling element or a wall element can be adapted.

DISCLOSURE OF THE INVENTION

This object is achieved in a holder for fastening a luminous element to a ceiling element or to a wall element comprising a substantially cylindrical base body which extends along a longitudinal axis from a base body start to a base body end and has an outer surface, an element on the outer surface for adjustable fixing in the direction of the longitudinal axis, in particular an external thread, is arranged, wherein in the area of the base body end at least one spatula element is arranged, which spatula element protrudes in a first direction from the base body, wherein the first direction has at least one directional component, which directional component in a normal to the longitudinal axis is the normal plane, achieved according to the invention in that the holder further comprises at least one plate element and at least one cooling element, the plate element having a, preferably cylindrical, opening, in w This opening of the base body is held by means of the element for adjustable fixation in the direction of the longitudinal axis, in particular by means of the external thread by a screw connection, the cooling element being connected to the base body in the area of the base body start, and the cooling element having a larger diameter normal to the longitudinal axis than the opening.

Because the cooling element now has a larger diameter, the installation depth can be reduced with the same cooling performance. The diameter of the base body in which the luminous element is inserted can be kept relatively small in accordance with the diameter of the luminous element because when the luminous element is changed, only the luminous element actually has to be removed from the basic element, but not the cooling element, which is used when changing the Luminous body remains in the holder. In this respect, the maintenance of the system consisting of the holder and the luminous element is also facilitated by the separation of the luminous element and the cooling element for the luminous element.

The plate element can be, for example, a gypsum fiber board which has a cylindrical shape at least in sections.

A thread is preferably used as an element for adjustable fixing in the direction of the longitudinal axis. Such an external thread on the outer circumferential surface of the base body enables the base body to be attached to the plate element. It would be conceivable that the base body with its external thread is screwed directly into the plate element, an inner surface of the plate element delimiting the opening being cut at least in sections by the external thread.

Furthermore, it would be possible for the base body to be held in the opening by means of an internal thread of a counter-element, for example a nut, which is in engagement with the external thread. The counter-element can be fixed on a rear side of the plate element before the plate element is built up, for example fastened or glued in a form-fitting manner. However, it would also be conceivable that the counter-element is fastened, for example glued, in the opening. In addition, it is also conceivable that the fastening element is arranged in the opening and locked or tightened with the counter element on the back of the plate element so that the counter element does not need to be additionally fixed or glued to the back of the plate element.

As an element for adjustable fixation in the direction of the longitudinal axis, however, one or more latching elements could also be provided on the base body, which engage in corresponding counter-elements on the plate element, for example in counter-elements in the opening of the plate element. To this The base body can be pushed and fixed into positions along the longitudinal axis defined by the locking elements.

By correspondingly turning the base body in the case of the external thread (or by correspondingly pushing in or pulling out the base part in the case of a snap connection), it is possible to set exactly how much the base body, in particular the spatula element, protrudes beyond the plate element. This means that if a layer of filler or plaster is applied to the plate element, by rotating the base body (or by pushing in or pulling out the base part accordingly in the case of a snap-in connection), the base body can move the plate element - without a layer of filler or plaster - by exactly Thickness of the filler or plaster layer protrudes. This enables the base body, in particular the filler element, to be flush with the filler or plaster layer, which is also associated with a good hold of the base body in the filler or plaster layer.

As already mentioned above, it would be conceivable that the putty element forms a protruding defined boundary up to which the putty or plaster layer is applied. The filler element enables a well-defined, flush finish of the filler or plaster layer to the base body to be easily created.

It would be conceivable that the spatula element has one or more recesses into which a corresponding tool can be inserted in order to be able to rotate the base body without difficulty. For example, it can be a slot-shaped recess into which a screwdriver can be inserted.

In the operating state of the holder, that is to say when the base body is connected to the plate element and the at least one cooling element, the at least one cooling element is behind the plate element when viewed in the direction of the longitudinal axis arranged if it is assumed that the front of the plate element faces into the room to be illuminated when the plate element is attached to or in a ceiling or wall element. It would be conceivable that the cooling element and the start of the base body are connected to one another by means of a screw connection. It could, however, also be the case that the cooling element and the start of the base body are connected to one another by means of a rivet connection or an adhesive connection. The connection between the cooling element and the base body does not have to be detachable, because the cooling element does not have to be dismantled after the holder has been installed in a ceiling or wall element and is also not accessible without removing the ceiling or wall element.

Of course, it would also be conceivable for several cooling elements to be arranged one behind the other and / or next to one another behind the plate element, as seen in the direction of the longitudinal axis.

Viewed normal to the longitudinal axis, the cooling element has a larger diameter than the opening of the plate element. In the context of this invention, diameter is understood to mean a shortest distance between those two points on a surface of the cooling element which points are most distant from one another.

On the one hand, the larger diameter of the cooling element compared to the opening of the plate element ensures good cooling. On the other hand, the height of the cooling element can be reduced as a result, since most of the cooling element extends normal to the longitudinal axis, whereby the installation depth of the holder according to the invention is reduced.

The geometric shape of the cooling element can vary. For example, viewed from above along the longitudinal axis, the cooling element can have an at least partially polygonal shape or preferably an at least partially circular shape. Correspondingly, the cooling element can have the shape of a polygon or at least in sections preferably have the shape of a cylinder at least in sections. A steady smooth contour of the cooling element or elements, in particular the circular shape, prevents the cooling element from getting stuck when rotating on other devices, for example on the fixing elements for fixing the plate element on a ceiling or wall element, or on cables that run between the ceiling or wall element and solid wall.

In a further embodiment variant of the invention, it is provided that the at least one cooling element is a flat cooling plate that is oriented normal to the longitudinal axis. In addition to the good cooling properties, the corresponding alignment also results in a particularly small installation depth of the holder according to the invention.

It would be conceivable that the cooling plate has at least one opening, on the one hand to improve the air circulation and on the other hand to save material and weight of the cooling plate.

In a further embodiment variant of the invention it is provided that the diameter of the at least one cooling element is a multiple of a diameter of the opening. The diameter of the cooling element can be about twice, three times or four times, preferably five times, six times or seven times compared to the diameter of the opening. However, the diameter of the cooling element can be any value greater than seven times the diameter of the opening, as well as any value between two to seven times the diameter of the opening.

The diameter of the cooling element is at least twice as large as the opening of the plate element. On the one hand, this results in good cooling of the luminous element and, on the other hand, it ensures a small installation depth of the holder according to the invention. As a rule, the diameter of the cooling element is smaller than a diameter of the plate element. This has the advantage that the bracket, comprising the cooling element mounted thereon, can in principle be inserted into the ceiling or wall element from both sides.

In a further embodiment of the invention it is provided that the holder comprises at least one connecting element, which connecting element is arranged between the base body and the cooling element. That is, the connecting element is arranged behind the plate element, seen in the direction of the longitudinal axis, and is used to mechanically connect the base body and the cooling element. At the same time, the connecting element can have an electrically insulating effect in order to separate the usually metallic cooling element from an electrical connection which is provided for the luminous element on the base element. The connecting element is designed such that a built-in luminous element is in thermal contact with the cooling element.

In a further embodiment variant of the invention it is provided that the holder comprises at least one connection board for an electrical connection of the luminous element. The connection board is a connection part which can interact with another connection part in order to establish an electrical connection.

In a further embodiment variant of the invention it is provided that the at least one connection board is arranged between the plate element and the connecting element. That is to say, the connection board is arranged behind the plate element and in front of the connecting element, as seen in the direction of the longitudinal axis. This ensures that the connection board is not in direct contact with the cooling plate, since it is spatially separated from the cooling element by the connecting element. The connecting element is held, for example clamped, between the connection board and the cooling element, for example by means of screws or the like.

In a further embodiment variant of the invention it is provided that the at least one plate element comprises at least one fixing element for fixing to a ceiling element or wall element. The at least one fixing element serves, on the one hand, to align the plate element and, on the other hand, prevents the plate element from slipping along the longitudinal axis.

At least one fixing element can be, for example, a rotatable bolt or a screw with a wing element arranged at the end of the bolt or the screw, which wing element is supported on the rear side when the bracket is mounted in a ceiling or wall element. The wing element thus prevents the holder from slipping out of the ceiling or wall element into the room to be illuminated. In addition, it would be conceivable that the at least one fixing element then comprises at least one stop element which interacts with the wing element.

In order to prevent the plate element from being pushed too far into the ceiling or wall element, several extensions can be provided in the radial direction on the circumference of the plate element, which extensions are pressed into the ceiling or wall element. Together with any wing elements, these extensions define the position of the plate element in both directions along the longitudinal axis.

As an alternative to wing elements and extensions, fastening straps are also conceivable as fixing elements, which are firmly connected to the plate element, for example by means of a screw connection, and can later be firmly connected to the ceiling or wall element, for example by means of a screw connection. These fastening tabs fix the position of the plate element in both directions along the longitudinal axis when the plate element is attached to the ceiling or wall element.

In principle, in the case of a screw connection, the base body, which is connected to the at least one cooling element, can be rotated with respect to the plate element due to the screw connection. However, it would also be conceivable that the base body can only be rotated to a limited extent or not at all in the operating state. Therefore, in a further embodiment of the invention it is provided that the at least one plate element comprises at least one locking element for locking the at least one cooling element against rotation relative to the plate element. In order to prevent undesired rotation of the at least one cooling element with respect to the plate element, the at least one locking element is provided. For example, the at least one locking element can be a locking spring.

The at least one locking element can interact in different ways with the at least one cooling element. It would be conceivable, for example, that the at least one locking element only exerts pressure on a circumferential area of the at least one cooling element. Therefore, in a further embodiment of the invention it is provided that the at least one locking element rests against the at least one cooling element and is designed such that it brakes a rotation of the at least one cooling element relative to the plate element by friction. This offers resistance to unwanted twisting. Nevertheless, the base body can be continuously adjusted until the bracket is plastered in. This means that the base body can be adapted at any time to the thickness of a layer of filler or plaster that has yet to be applied.

However, it would also be conceivable that the at least one locking element interacts with the at least one cooling plate in such a way that a form-fitting locking occurs. For this reason, it is provided in a further embodiment of the invention that the at least one cooling element in a circumferential area at least has a recess for receiving the locking element. As soon as the locking element engages in the recess, rotation of the base body is no longer possible, since the cooling element is positively locked with the locking spring and can no longer be rotated. That is to say, in this embodiment variant, the base body can only be rotated in the opening of the plate element before the holder is installed in a ceiling or wall element.

Of course, a combination of the two variants outlined above would also be possible. It would be conceivable, for example, that the cooling element has a latching structure in the circumferential area, into which the locking spring engages. This means that permanent adjustment of the base body is possible in the mounted state of the bracket on a ceiling or wall element, but locking points can be felt.

In principle, the base body, which is connected to the at least one cooling element via a latching connection, can also have a locking element, for example a stop, beyond which no relative displacement along the longitudinal axis is possible.

In a further embodiment of the invention it is provided that the holder has an installation depth running along the longitudinal axis of a maximum of 7 cm, preferably a maximum of 6 cm, particularly preferably a maximum of 4 cm. The holder according to the invention can thus also be installed in ceiling or wall elements where there is little space behind the cavity. That is, the brackets according to the invention enable a wide range of uses, since they can be installed on a wide variety of ceiling or wall structures.

Furthermore, according to the invention, a system comprising a holder according to the invention and at least one luminous element is provided, the luminous element being detachable in an interior of the base body, in particular detachable without tools, can be arranged. “Without tools” is understood here to mean that no screwdriver is necessary to install a luminous element in the holder or to detach it from it. Corresponding depressions in the luminous element can make it easier to release the luminous means from the holder by means of means available every day, for example a coin or just by hand, for example by rotating the luminous means by an angle, in particular less than 180 °, for example 90 °.

In the context of the invention, the term luminous body is to be understood as meaning all electrical equipment and electrical loads that are used to generate light.

In order to be able to connect the luminous element comfortably and simply to the holder according to the invention, a fastening structure known per se for the luminous element is preferably formed on an inside of the base body, in particular a projection, a shoulder, a thread, a bayonet fastener part, a snap fastener part or a magnetic fastener part.

The luminous element is preferably brought into direct contact with the cooling element.

In a further embodiment of the system according to the invention, it is provided that the at least one luminous element comprises a circuit board, in particular a circuit board with at least one light-emitting diode, which circuit board can be placed in a corresponding recess in the connection board and contacted with the cooling element. In particular, the board can be passed through a corresponding recess in the connection board in order to establish contact with the cooling element. In other words, when the board is inserted into the connection board, a form-fitting connection is formed which holds the luminous element in the holder. For this purpose, springs can be provided on the board.

The circuit board is a carrier for electronic components. The board is used for the electrical connection to a current or voltage source.

As can be seen from the above explanations, the holder according to the invention can be used in various ceiling or wall constructions. In accordance with what has been said above, according to the invention a ceiling element or wall element comprising a holder according to the invention is therefore provided, the holder being held flush in a recess of the ceiling element or of the wall element. A corresponding cavity is preferably provided behind the ceiling or wall element in order to facilitate the assembly of the holder according to the invention. The ceiling or wall element can be a gypsum fiber board.

There is therefore no need for a substructure on a fixed wall behind the ceiling or wall element for the holder according to the invention. It is sufficient if the ceiling or wall element has a generally circular recess corresponding to the holder.

It would be conceivable that the plate element is held flush in the recess of the ceiling or wall element with the aid of the at least one fixing element.

In a further embodiment of the ceiling element or wall element according to the invention it is provided that a filler layer or plaster layer applied to the plate element has a thickness that essentially corresponds to a distance measured along the longitudinal axis between the plate element and the adjustable filler element.

As already described above, it would be conceivable that, by rotating the base body, it is possible to set precisely the distance by which the base body, in particular the spatula element, protrudes beyond the plate element. Corresponding a layer of filler or plaster can then easily be applied, the thickness of which corresponds exactly to the distance.

WAYS OF CARRYING OUT THE INVENTION

Fig. 1 shows an axonometric view of an exploded view of a first embodiment of a system according to the invention comprising a holder 1 according to the invention and a luminous element 2 from obliquely above, while Fig. 2 an axonometric view of an exploded view of the first embodiment of the system according to the invention Fig. 1 from diagonally below. The holder 1 according to the invention comprises a base body 4, a plate element 13 and a cooling element 14.

The cylindrical base body 4 extends along a longitudinal axis 5 from a base body start 6 to a base body end 7 and has an outer jacket surface 8, on which jacket surface 8 an external thread 9 is arranged. Furthermore, in the area of the base body end 7, a spatula element 10 that completely surrounds the base body end 7 is arranged, which extends in a first direction 11 from Base body 4 protrudes, the first direction 11 being normal to the longitudinal axis 5.

The plate element 13 has a cylindrical opening 15 in which the base body 4 is held in an operating state, the operating state being understood to mean the assembled holder 1 according to the invention - that is, in the operating state the base body 4 is held in the opening 15 of the plate element 13 and the cooling element 14 is connected to the base body 4 in the area of the base body start 6.

In this exemplary embodiment, the base body 4 is held in the opening 15 by means of an internal thread 26 of a mating element 25, in this case a nut, which is in engagement with the external thread 9. Fig. 3 shows an axonometric view of an exploded view of the plate element 13 and the counter element 25 of the first embodiment of the holder 1 according to the invention Fig. 1 , wherein the counter element 25 is fixed on a rear side of the plate element 13 in a corresponding recess.

Fig. 4 shows an axonometric view of an exploded view of a cooling element 14, a connecting element 16, a connection board 17 and a base body 4 of the first embodiment of the holder 1 according to the invention Fig. 1 In the operating state, the cooling element 14 is arranged behind the plate element 13, as seen in the direction of the longitudinal axis 5. In this embodiment, the cooling element 14 is designed as a flat cooling plate, which is aligned normal to the longitudinal axis 5, wherein a diameter of the cooling element 14 is approximately five times as long as a diameter of the opening 15. The cooling element 14 has a large number of openings, which the Material and weight savings serve as well as enable air to circulate through and around the cooling element 14. It would also be conceivable to arrange several cooling elements 14 parallel to one another.

In the operating state, a connecting element 16 is arranged between the base body 4 and the cooling element 14, which in the first exemplary embodiment is also designed as a nut, in particular as a plastic nut.

Furthermore, the holder 1 according to the invention comprises a connection board 17 which, in the operating state, is arranged between the plate element 13 and the connecting element 16 and can be connected to a voltage source or current source (not shown).

The connection board 17 is pushed over the start of the base body 6 and rests with inwardly directed extensions in two recesses in the base body 4. The internal thread of the connecting element 16 is screwed onto the external thread of the base body 4. The cooling element is placed on the connecting element 16 and screwed to the connection board 17 by means of screws, which here run outside the connecting element 16, which has corresponding bores for this purpose.

In this exemplary embodiment, the plate element 13 also comprises three fixing elements 18 (see FIG Fig. 1 ), which are used to fix the holder 1 according to the invention to a ceiling or wall element 3. Each of the three fixing elements 18 has a rotatable screw 27 with a wing element 28 fixedly arranged on the end of the screw. In this exemplary embodiment, the screw 27 can be easily rotated with the aid of a screwdriver. In addition, each of the three fixing elements 18 comprises a stop element 29 which facilitates the fixing. With the aid of the wing elements 28, the holder 1 according to the invention in this exemplary embodiment is suspended in a corresponding recess 24 of the ceiling or wall element 3 in such a way that the holder 1 is held flush.

In order to prevent the plate element 13 from being pushed too far into the ceiling or wall element 3, there are six extensions 32 in the radial direction on the circumference of the plate element 13 provided which protrude beyond the circular contour of the plate element 13. No corresponding recesses are provided in the ceiling or wall element 3, so that the extensions 32, such as teeth or claws, are pressed into the surrounding ceiling or wall element 3. Together with the wing elements 28, these extensions 32 define the position of the plate element 13 in both directions along the longitudinal axis 5.

Locking elements 12 (see Fig. 8 ) are not provided in this exemplary embodiment, ie the base body 4 can be rotated at any time without resistance.

Fig. 5 shows an axonometric view of the first embodiment of the holder 1 according to the invention from Fig. 1 from obliquely above while Fig. 6 an axonometric view of the first embodiment of the holder 1 according to the invention Fig. 1 from diagonally below. The very small installation depth 21 of the holder 1 according to the invention can be clearly seen from these two figures. In this embodiment, the holder 1 according to the invention has an installation depth 21 of only 4 cm, whereby the holder 1 according to the invention can also be installed in ceiling or wall elements 3 that have a very small cavity behind them.

Fig. 7 shows an axonometric view of an exploded view of the luminous element 2, which is included in the system according to the invention and can be used in all exemplary embodiments. In its operating state, the luminous element 2 is arranged and fixed in an interior 22 of the base body 4, for example by means of a bayonet connection part and / or by means of springs, and comprises a board 23 with a light-emitting diode 35, which board 23 is passed through a recess in the connection board 17, until the circuit board 23 makes contact with the cooling element 14. An electrical connection to the connection board 17 is established by flexible springs 34 soldered to the board 23. Additional, no The springs shown on the circuit board 23, which are supported on the connection circuit board 17, have the effect that the circuit board 23 rests on the cooling element 14. The electrical contact between the board 23 and the connection board 17 is produced at the same time as the mechanical locking by means of a rotary movement, similar to a bayonet lock. The mechanical lock can simply be opened by hand or a coin and the luminous element 2 can be exchanged.

Furthermore, the luminous body 2 comprises further optical elements, such as a reflector 30 here. Alternatively or additionally, a lens could also be provided. A glare shield 31 can be pressed or glued to the board 23. The anti-glare ring 31 can also be suspended in springs on the plate 23.

By correspondingly turning the base body 4, it is possible in this exemplary embodiment in the operating state to set exactly how much the spatula element 10 projects beyond the plate element 13. That is, if a filler or plaster layer is applied to the plate element 13, by turning the base body 4 it can be achieved that the filler element 10 protrudes over the plate element 13 - without a filler or plaster layer - by exactly the thickness of the filler or plaster layer. This enables the filler element 10 to be flush with the filler or plaster layer, which is also associated with a good hold of the base body 4 in the filler or plaster layer.

The larger diameter of the cooling element 14 compared to the diameter of the opening 15 of the plate element 13, on the one hand, ensures good cooling. On the other hand, the height of the cooling element 14 can thereby be reduced, since the largest part of the cooling element 14 extends normal to the longitudinal axis 5, whereby the installation depth 21 of the holder 1 according to the invention or of the system according to the invention is reduced.

Fig. 8 shows an axonometric view of the second embodiment of the holder 1 according to the invention obliquely from above. The structure of the holder 1 according to the invention of the second exemplary embodiment corresponds to the structure of the holder 1 according to the invention of the first exemplary embodiment, with the difference that a locking element 12, which is designed as a locking spring, is provided.

In the second exemplary embodiment, the cooling element 14 has a recess 20 for receiving the locking element 12 in a circumferential region 19. As soon as the locking element 12 engages in the recess 20 in the operating state, rotation of the base body 4 is no longer possible, since the cooling element 14 is positively locked with the locking element 12 and can no longer be rotated. That is to say, in this exemplary embodiment, the base body 4 can only be rotated in the opening 15 of the plate element 13 before the holder 1 is installed in a ceiling or wall element 3.

Fig. 9 shows an axonometric sectional view of the second embodiment of the system according to the invention, which is arranged in a ceiling element 3. The plate element 13 is held flush in a recess 24 of the ceiling element 3 with the aid of the fixing elements 18.

The assembly and installation of the system 1 according to the invention in the ceiling element 3 can be briefly summarized as follows:
At the beginning, the base body 4 is screwed into the plate element 13 and held in the opening 15 by means of the internal thread 26 of the counter element 25 which is in engagement with the external thread 9. Furthermore, the start of the base body 6 is inserted into the recess of the connection board 17 and then screwed to the connecting element 16.
