Description

Mounting system for fastening at least one lamp unit in an elongated, curved mounting hole

The invention relates to a fastening system for fastening at least one lamp unit in an elongated, curved mounting hole.

Such a fastening system is known from EP 2 243 998 AI. This known fastening system comprises a plurality of segments, which are U-shaped in cross-section and which are arranged in a row one behind the other, so that they form a receiving area for the at least one lighting unit. Between the free ends of the U-legs, a light exit region for emitting a light emitted by the at least one lamp unit light is formed. The segments are mutually movable to a certain extent, so that the fastening system is particularly suitable for installation in an overall elongated, curved mounting hole. To cover the light exit area a translucent plate or alternatively a translucent, textile fabric is provided, which is held taut between the free ends of the U-legs by means of Keder elements. In principle, a textile fabric can be more easily adapted in shape to the oblong, curved installation opening than a plate which consists of a dimensionally stable material.

In general, it is desirable in such a fastening system that

Make light exit area so that its width, so the dimension across the total elongated extent appears as uniform as possible. Practice has shown that the human eye here already very small irregularities in the width dimensions registered and these can be distracting. The goal of a uniform width as possible leads to a special

Challenge when mounting the mounting system in the mounting hole. In the known fastening system is provided for mounting as a possibility, the fastening system initially fixed to the wall or ceiling side

To attach rail elements and then mount the wall or ceiling element. This first requires a particularly precise fixation of said rail elements and is also not suitable in a case in which the Mounting system to be installed after installation of the wall or ceiling element.

According to an alternative, the holder in the mounting hole locking or

Fasteners provided, which from the installation side of the wall or

Contact ceiling element. These locking or fastening elements are mounted laterally on the U-legs of some segments. However, this embodiment has proved in practice to be particularly production-intensive and expensive with respect to the assembly. In addition, a double-walled version of the wall or ceiling element is provided in this case, whereby the overall design of the arrangement is particularly complex. In addition, this form is less suitable for covering the light exit area by a tensioned tissue, because the fixation of the segments comparatively far away from the free end portions of the U-leg attacks and the latter therefore tend to have a certain freedom of movement.

The invention has for its object to provide an improved fastening system. In particular, the attachment system at low

Production costs allow easier installation; In this case, a particularly even appearing width profile of the light emitting area should be achievable.

This object is achieved according to the invention with the objects mentioned in the independent claims. Particular embodiments of the invention are indicated in the dependent claims.

According to the invention, there is provided a fastening system for fastening at least one lamp unit in an elongate curved mounting opening of a wall or ceiling element which separates a room side from a mounting side. The fastening system has a plurality of, in cross-section U-shaped segments for forming a Aufhahmebereichs for the at least one lamp unit, each of the segments at the two free ends of the two U-legs in each case one with respect to the U-shape outwardly facing flange to

has room-side contact with the wall or ceiling element. The flange is in this case as engagement element for a connecting means for fixing the relevant Segments configured on the wall or ceiling element and the fastening system further comprises a profile element for installation-side contact with the wall or ceiling element, which is designed as an abutment for the connecting means.

By the profile element is achieved that no locking or fastening element is required laterally on a U-leg of a segment for mounting the fastening system to the wall or ceiling element. This is a particularly immediate and secure fixation of the free end portions of the U-legs on

Edge region of the mounting hole allows. Due to the particularly immediate fixation of the free ends of the U-legs can be achieved that the width of the light exit area can be fixed very well. Also can be achieved by a particularly immediate fixation of the free end portions of the U-legs, that the fastening system is particularly well suited for a translucent cover of a fabric or a textile material, which is supported under tension between the end regions.

It is possible by the use of the flange that at the

Production of the mounting hole tolerances can be relatively large.

Overall, can be increased in this way the ease of installation and it can also reduce the cost of production. Furthermore, the fastening system is also suitable for mounting on a single-walled wall or ceiling element.

Preferably, the profile element has an L-shape in cross-section, wherein it is connected to one of the two L-legs for installation-side contact with the wall or

Ceiling element is designed. As a result, the system of the profile element for mounting on the edge region of the mounting hole is facilitated.

Preferably, the profile element has a plurality of holes for guiding the

Connecting means, wherein the holes are arranged at different distances from a lateral edge region of the profile element. This can be achieved that for a reliable fixation of the fastening system in the Installation opening in the manufacture of the mounting hole, the requirements for the accuracy of the width dimension can be kept particularly low.

Preferably, the profile element has notches, which are designed such that a bending of the profile element is facilitated by them. As a result, the profile element can be particularly well adapted to a curved portion of the edge region of the mounting hole in its shape.

Preferably, the profile element consists of sheet metal, in particular of

Tinplate.

According to another aspect of the invention is a fastening system for

Attachment of at least one lamp unit in an elongated curved mounting opening of a wall or ceiling element which separates a room side from a mounting side provided. The fastening system has several, in

Cross-section U-shaped segments to form a receiving area for the at least one lamp unit. The fastening system may also be a fastening system having the features described above. In this case, each of the segments has a stiffening element, which is arranged between the two concerned U-legs.

By stiffening the U-legs are in the assembly of the

Mounting system held in the mounting hole in a certain, fixed distance from each other. As a result, the relevant segment can be installed particularly easily with a defined distance between the two free end regions of the U-legs. In this way it can be achieved with a particularly simple assembly that the light output region has a particularly uniform width viewed lengthwise. Preferably, the stiffening element at its two contact points to the U-legs each have a predetermined breaking point, which is designed to facilitate breaking out of the stiffening element after installation of the fastening system in the mounting hole. As a result, the assembly is further facilitated. Preferably, the fastening system further comprises a piping holding profile for holding a welt on at least one of the two free ends of the two U-legs concerned. As a result, the fastening device is particularly suitable for a textile fabric, which is arranged overlapping the light entry area.

Preferably, a receiving groove for holding the piping holding profile is formed on the at least one of the two free ends of the two respective U-legs. Particularly preferably, the fastening system also has a latching device for latching retention of the piping holding profile in the receiving groove. As a result, the assembly of the piping holding profile is facilitated.

Preferably, the piping holding profile has a spatula edge pointing in the installed state toward the room side. This makes it easier to fill the room-side edge region of the installation opening after mounting the fastening system.

Preferably, the piping holding profile made of plastic, in particular of an impact resistant, flexible plastic, such as PC (polycarbonate).

The invention is explained in more detail below with reference to an embodiment and with reference to the drawings. Show it:

Fig. 1 is a perspective sketch of an inventive

Fastening system

2 shows a detail from FIG. 1,

Fig. 3 is a, the Fig. 1 corresponding cross section and

Fig. 4 is a perspective sketch of a portion of a profile element.

In Fig. 1 is a perspective sketch of an embodiment of a fastening system according to the invention is shown, in Fig. 3, a corresponding cross-section is sketched. The fastening system is for fastening at least one (in the figures not shown) designed lighting unit. The luminaire unit can be, for example, an LED light source with a circuit board and a plurality of LEDs arranged thereon. The fastening system is designed for fastening the lamp unit in an elongated, curved mounting opening of a wall or ceiling element 2, which separates a room side R from a mounting side E. The mounting hole can be a total of several meters long and bent or curved, while also repeatedly and curved in different directions designed to be running.

The fastening system is accordingly designed such that it can bend or bend, so that it is adapted in its shape to the shape of the mounting hole.

Accordingly, the fastening system also extends along a

Main extension L, which is correspondingly curved. For example, curvature radii of co can be provided up to about 2 meters.

The fastening system for this purpose comprises a plurality of segments 3, which have a U-shape in a cross section normal to the main extension L. Accordingly, viewed in cross section, a segment 3 shows two U-legs 6, 6 ', as well as a, the two U-legs 6, ^6' interconnecting connecting leg 6 ^". On an the connecting legs ^6" opposite side have the U-legs 6 , 6 ^' accordingly free ends 5, 5 ^' . The segments 3 can be designed as injection-molded parts.

For installation, it is provided that the fastening system is installed aligned in the mounting hole, that the U-legs 6, 6 'point with their free ends 5, 5' to the room side R out. A delivery of the at least one

Luminaire unit radiated light is provided between the two free ends 5, 5 'in the space inside. The segments 3 are preferably aligned so as to form together a kind of "bead", the orientation of the segments 3 continuing continuously from one to the next segment 3. In the one of the U-legs 6, 6 'of the segments 3 and Connecting legs 6 "of the segments 3 covered space is formed in this way a receiving area 4, which is provided or configured for receiving the at least one lighting unit. Each segment 3 has at its two free ends 5, 5 'of the two respective U-legs 6, 6' in each case one, with respect to the U-shape outwardly facing flange portion 7, 7 ', for the room-side contact with the wall - or

Ceiling element 2 is provided. The flange region 7, 7 'is configured as an engagement element for a connecting means V, in particular a screw, for fixing the relevant segment 3 to the wall or ceiling element 2. For example, the flange region 7, 7 'for this purpose have at least one feedthrough hole 71, which is designed to pass through the connection means V. For example, this may be a countersunk hole, in particular for a countersunk screw.

It is preferably provided that the flange region 7, 7 ^'has at least two, for example at least three, corresponding through holes 71. Furthermore, the fastening system comprises a profile element 8, which is provided for installation-side contact with the wall or ceiling element 2 and is designed as an abutment for the connecting means V. In Fig. 4, a portion of the profile element 8 is sketched in perspective. For installation, it may be provided that, in a first step, the profile element 8 is arranged with its main axis along an edge region of the installation opening, in particular fixed and in a further step, the segments 3 are brought into their intended position and finally the connecting element V attached becomes. To fix the profile element 8 only in some places or partially fixed. In this way, it is possible to ensure that the flange area 7, 7 ', which is located directly at the free end 5, 5' of the respective U-leg 6, 6 ', fixes firmly and reliably on the edge area of the installation opening from the room side R forth leaves.

Accordingly, the design of the fastening system is preferably such that the profile element 8 to the segments 3 has no structural connection, as long as the fastening system is not installed in the mounting hole. In this sense, the profile element 8 thus represents a separate component that can be handled independently of the rest of the fastening system.

Advantageously, the profile element 8 is designed so long that it extends in the installed state - viewed along the main extension L - over several adjacent flange portions 7 and is designed for all these flange portions 7 analogous as an abutment. As a result, the number of components is reduced overall and the assembly continues to facilitate.

Preferably, the profile element 8 has an L-shape in cross section, so that it comprises two legs 81, 82. One of the two legs - in the example shown, the leg designated by 81 - is configured for installation on the wall or ceiling element 2. The other leg 82 may be provided for abutment with an edge region of the installation opening facing towards the center of the installation opening. Preferably, viewed in cross-section, the leg 81 designed for installation on the wall or ceiling element 2 is wider than the other leg 82.

To be able to bend the profile element 8 so well that it adapts to the course of the installation opening, it preferably has notches 86, 87, in particular lateral incisions. The cuts 86, 87 are preferably formed on both legs 81, 82, in particular in each case offset from each other, as shown in Fig. 4 by way of example.

As further shown by way of example in FIG. 4, the profile element 8 preferably has a plurality of holes 85 which are used to guide the connecting means V during assembly are provided. The holes 85 are preferably in different

Distances from a lateral edge region 83 formed, in particular at different distances to an edge region parallel to the main axis of the profile element 8. The holes 85 are accordingly suitably formed in that leg 81, the installation-side contact with the wall or

Ceiling element 2 is configured.

Preferably, the holes 85 are of uniform diameter and thereby formed with small mutual distances. For example, it may be provided that the holes 85 are formed in groups and within a group of the mutual distance between the holes 85 is at most twice as large as the diameter of the holes 85, preferably at most equal to the diameter of the holes 85. This makes it possible to achieve that the accuracy in fixing the profile element 8 can be reduced and yet a reliable abutment for the connecting means V is formed; a corresponding screw is tightened when screwing self-centering in one of the holes 85. In the example sketched in Fig. 4, the holes 85 in groups of 149 holes

summarized. Only one of the incisions 86 is formed between the groups.

The profile element 8 is preferably made of sheet metal, in particular tinplate.

Further preferably, each of the segments 3, in particular web-shaped stiffening element 9, which is disposed between the two respective U-legs 6, 6 '. Advantageously, the stiffening element 9 is a part of the segment 3, which is injected in the production of the segment 3. During assembly, the two U-legs 6, 6 'are held by the stiffening element 9 at a specific, defined distance, so that the fastening system can be particularly easily fixed in the installation opening such that it has a particularly uniform width.

If the stiffening element 9 at its two contact points to the U-legs 6, 6 ^' each have a predetermined breaking point 91, 92, it can be particularly easy to solve after installation of the fastening system by simply breaking out. Furthermore, the fastening system advantageously has a piping holding profile 10 for holding a welt 11 on at least one of the two free ends 5, 5 'of the two respective U-legs 6, 6'. Preferably, such a piping holding profile 10 is arranged at both free ends 5, 5 ^' . The piping holding profile 10 is preferably designed so long that, viewed in the main extension L, it extends over a plurality of segments 3.

As outlined by way of example in the figures, the piping 11 serves to hold a translucent cover 15, which is held taut as a light exit element between the two free ends 5, 5 '. The cover 15 may for example consist of a flexible plastic, for example, the cover 15 may be formed by a PVC film, on the one hand, the desired optical

Properties and on the other hand required with respect to the curvature of the mounting hole flexibility. The piping 11 may for example consist of silicone. The piping 11 may be connected to the cover 15 by sewing.

For holding the piping holding profile 10 is advantageously formed on the segment 3 at the relevant free end 5, 5 ^' a receiving groove 12, in particular for latching support of the piping holding profile 10. In the illustrated embodiment, the fastening system for this purpose a latching connection 13 which designed for latching mounting of the piping holding profile 10 in the receiving groove 12.

For example, the locking connection for this purpose one at the free end

comprise trained barbs, which engages in a corresponding recess on the piping holding profile 10. The configuration can be provided that the piping-retaining profile 10 is no longer removed after mounting in the receiving groove 12.

If desired, the fastening system according to a variant without the

Flange areas 7, 7 ^'to produce, so for example as a cultivation or

Pendulum variant, it can be provided that an injection molding plant for the production of the segments 3 at the relevant points has a slot, but the

Containing groove 12 for the piping holding profile 10. The Keder-Halteprofü 10 may for example consist of plastic, in particular of an impact-resistant, flexible plastic, such as PC.

The piping holding profile 10 may still have a spatula edge 14 pointing toward the room side R. As a result, the edge region of the installation opening on the room side can be spatulated particularly well on the room side after installation of the fastening system; it is therefore very easy to achieve a ceiling-flush finish. The spatula edge 14 may for example have a width between 1 mm and 3 mm, in particular a width of about 2 mm.

The fastening system according to the invention offers in comparison to a

conventional Rigips stretch ceiling solution, in particular with respect to the assembly a considerable time advantage and improved comfort. It also allows for a reduced finish.
