Description

System for mounting on a suspended bus bar and method for mounting the system on a bus bar

The present invention relates to a system for mounting to a suspended bus bar, a bus bar system having a bus bar and the system, and a method for mounting the system to a bus bar.

It is known to use bus bars suspended from a ceiling as part of a light fixture assembly. For example, a plurality of lighting elements inserted into the bus bar can be provided for this purpose. In this case, it is also known to insert the bus bars entirely into the channel profile in order to obtain a suitable, attractive appearance of the assembly in this way. As shown in fig. 9a), the wire groove profile can be, for example, an H-shaped profile part 100, into which the corresponding busbar 101 is pushed. Another embodiment with an H-shaped wire groove profile is shown in fig. 9 c). The busbar itself can also be designed as a wire-channel profile as shown in fig. 9b) and d).

If the busbars which are already mounted in a suspended manner are to be subsequently equipped with corresponding trunking in order to obtain a change in appearance, the busbars must first be removed from the ceiling so that they can be pushed into the corresponding trunking profiles. This involves a very large amount of work, since in practice, at least in the field of light fixtures, assemblies comprising a plurality of busbars whose end faces are connected to one another are often used.

Another disadvantage of said prior art is that due to the H-shape of the trunking profile, cooling air circulation is practically not possible in the area between the busbars and the trunking profile. Thus preventing effective cooling of the bus bar.

The object of the invention is to provide a system for mounting on a bus bar, with which a favorable appearance can be achieved; in this case, in particular, an effective cooling of the busbar in the connected state should be possible. Furthermore, a corresponding bus bar system for lighting with a bus bar and such a system, and a method for mounting the system on a bus bar should be given.

According to the invention, this object is achieved by the objects of the independent claims. Particular embodiments of the invention are given in the dependent claims.

According to the invention, a system is provided for mounting on a busbar extending along a longitudinal axis, the busbar having a plurality of fixing clips which are designed for fixing on the busbar at different positions along the longitudinal axis. The system also has two side profile parts which, in the mounted state on the busbar, extend along the longitudinal axis on two opposite sides of the busbar. The side profile parts can be connected to the retaining clip by a snap connection.

By means of the two side profile parts, the appearance system of the assembly thus formed can be advantageously influenced. In this case, a particularly simple handling can be achieved by the retaining clip when the side profile parts are mounted. Due to the provision of two side profile parts, it is possible to obtain: vertical air circulation can be produced between the two side profile parts to cool the busbar.

Preferably, the retaining clips are each substantially U-shaped, so that two U-shaped sides and a connecting side connecting the two U-shaped sides to each other are formed, so that in the mounted state on the busbar the two U-shaped sides enclose the busbar on two opposite sides. Thereby, it is possible to obtain: in the installed state, the connecting edge lies flat on the busbar from above, so that a particularly reliable connection can be achieved. Furthermore, the two U-shaped legs are particularly suitable for forming the connection point of the two side profile parts.

The retaining clip is preferably designed such that, in the mounted state on the busbar, a distance is formed between the busbar and the side profile part, through which air can flow. This is advantageous for proper cooling of the bus bar.

Preferably, each of the fixing clips has a projection for connection with a side profile element extending transversely to the longitudinal axis. This makes it possible to connect the side profile parts to the busbar in a particularly suitable manner.

The projection here preferably comprises an upper hook element and a lower spring element on two opposite sides, respectively. This allows particularly simple handling when attaching the side profile part to the retaining clip.

Preferably, the side profile parts each have an inward L-shaped projection for hooking into the hook element. The mounting of the side profile parts is thereby further simplified, since for this purpose the side profile parts can be easily hung in the hook elements of the retaining clip in a first step.

Preferably, the side profile parts each have an inwardly directed snap element for connection with the spring element. The fastening of the side profile parts to the retaining clip is thereby further simplified, since the snap connection can be established particularly easily.

Preferably, the side profile parts are shaped such that they project downwards beyond the busbar in the mounted state on the busbar. The appearance can thereby be designed particularly well-balanced, since electrical components (e.g. lamps) which may be present can project below from the busbar and can be covered by the side profile parts.

It is advantageous in terms of production technology if the retaining clip is preferably designed to be structurally identical and/or the side profile parts are mirror images.

Advantageously, the retaining clip is preferably made of a plastic material and/or the side profile parts are made of aluminum.

According to another aspect of the present invention, there is provided a bus bar system having a bus bar arranged for suspension from a ceiling at a spacing, or the bus bar is suspended from a ceiling at a spacing, and a system according to the present application, wherein the system is mounted to the bus bar as arranged.

According to a further aspect of the invention, a method is provided for mounting a system according to the application to a busbar suspended at a distance from a ceiling, wherein the method has the following steps: a) fixing the retaining clip at different positions along the longitudinal axis on the busbar, and b) connecting the side profile parts to the retaining clip by means of a snap connection.

The invention is explained in detail below on the basis of embodiments and with reference to the drawings. The figures show:

FIG. 8 is a schematic view of the bus bar system from above, an

Fig. 9a) to d) different embodiments of a bus bar system according to the prior art.

FIG. 1 shows a schematic view of an embodiment of a bus bar system according to the present application, and FIG. 2 shows a detailed illustration thereof. The busbar system comprises a busbar 1 extending along a longitudinal axis L, which busbar is arranged for suspension from a ceiling at a distance or which busbar is suspended from a ceiling at a distance. For the sake of simplicity, the ceiling and the fixing of the bus bar 1 to the ceiling are not shown in fig. 1. For example, cables can be provided, by means of which the bus bar 1 is fastened to the ceiling. Alternatively, it may also be provided for fixing, for example by means of screws or the like.

The bus bar 1 can, for example, be designed as part of a lamp assembly, so that a lamp can be inserted into the bus bar 1, so that the lamp can be supplied with operating current via the bus bar 1.

The busbar 1 is here mounted as described above in such a way that it is at a distance, i.e. at a vertical distance, from the ceiling. This distance may be, for example, at least as large as the vertical extension of the busbar 1.

The bus bar system furthermore comprises a system according to the present application for mounting to a bus bar 1. The system comprises a plurality of fixing clips 2 designed for fixing on the busbar 1 at different positions along the longitudinal axis L. This is the case in fig. 3, in which the left-hand side shows a section of the busbar 1 in a perspective view, and two retaining clips 2, here in a state in which they have not yet been connected to the busbar 1. The right-hand side of fig. 3 shows a schematic cross-sectional view of one of the fixing clips 2 fixed to the busbar 1.

The system furthermore comprises two

side profile parts

3,4, which are indicated in fig. 1 and which, in the mounted state on the busbar 1, extend along the longitudinal axis L on two opposite sides of the busbar 1. Here, the design is such that: the

side profile parts

3,4 can be connected to the fixing clip 2 by means of a snap connection. The

side profile parts

3,4 can influence the appearance of the bus bar system to a large extent. Thus, the system according to the present application is particularly suitable for forming a "fascia" of a corresponding bus bar.

For this purpose, the outward faces of the

side profile parts

3,4, which are referenced to the busbar 1, can be designed flat, for example, as shown in fig. 1. This results in a particularly uniform appearance. The design is such in the example shown: the outward faces of the

side profile parts

3,4 are both oriented vertically. It is advantageously provided that these faces are at least substantially vertically oriented, for example forming an angle of less than 20 °, preferably less than 10 °, with the vertical.

Advantageously in terms of production, the retaining clips 2 can all be designed to be structurally identical. As shown by way of example in fig. 3, the fixing clips 2 are preferably each substantially U-shaped, so that two U-shaped sides 5,6 and a connecting side 7 connecting the two U-shaped sides 5,6 to one another are formed, so that the two U-shaped sides 5,6 enclose the busbar 1 on two opposite sides in the mounted state on the busbar 1. Fig. 6 shows a perspective schematic view of the retaining clip 2 and fig. 7 shows a cross-sectional schematic view of the bus bar system, wherein the retaining clip 2 is highlighted in hatched lines. In particular, the design may be such that: the connecting edge 7 lies flat on the busbar 1 from above in the connected state, as shown in fig. 3. The connecting edge 7 can have snap elements 20 for improved connection reliability, which are designed for a snap connection with corresponding parts of the busbar 1.

The extension of the retaining clip 2 in the direction of the longitudinal axis L is preferably significantly less than the length of the U-shaped legs 5,6, for example less than half the length of the U-shaped legs 5, 6.

As shown on the right half of fig. 3, the design is such in the example shown: the fixing clip 2 connected to the busbar 1 can be fixed directly from above on the busbar 1 by a vertically downwardly directed movement. In this case, the two U-shaped legs 5,6 slide down along the two side walls of the busbar 1 during this movement until the snap-in element 20 forms a snap-in connection with the busbar 1. The fixing clip 2 can thus be mounted on the busbar 1 as provided by a very simple operation.

For connection with the

side profile elements

3,4, each of the fastening clips 2 preferably has a

projection

8,9,10,11 extending transversely to the longitudinal axis L. The

projections

8,9,10,11 preferably comprise an upper hook element 8,9 and a

lower spring element

10,11 on two opposite sides, respectively.

As shown in fig. 4, the

side profile parts

3,4 preferably each have an inward L-shaped

projection

12,13 for hooking into the hook elements 8, 9. The

side profile parts

3,4 for connection to the retaining clip 2 can therefore be suspended very easily from above in the hook elements 8,9 of the retaining clip 2.

Furthermore, the

side profile parts

3,4 preferably each have an

inward snap element

14,15 for snap connection with the

spring elements

10,11 of the retaining clip 2. As shown in fig. 5, the design here is preferably such that: only a slight pressure from the outside towards the

side profile parts

3,4 can cause a snap connection to be established between the

spring elements

10,11 of the retaining clip 2 on the one hand and the inwardly directed

snap elements

14,15 of the

side profile parts

3,4 on the other hand.

It is thus possible to obtain: the

side profile parts

3,4 can be fixed to the retaining clip 2 by a very simple operation.

The L-shaped

projections

12,13 of the

side profile parts

3,4 preferably extend over the entire length of the

side profile parts

3, 4. It is thus possible to hang the

side profile parts

12,13 in the hook elements 8,9 of the retaining clip 2 without having to pay strict attention to the position of the respective retaining clip 2 along the longitudinal axis L at this time. It is advantageous in terms of production technology, for example, that the L-shaped

projections

12,13 can be designed in the form of a profile.

A similar applies to the

inward snap elements

14,15 of the

side profile parts

3, 4.

By means of said design it is possible in particular to obtain: if the busbar 1 is already in a state of suspended fixation from the ceiling, a system comprising the fixing clip 2 and the two

side profile parts

3,4 can be mounted as provided on the busbar 1. It is therefore not necessary to suspend the busbar 1 in order to install the system; this may mean a significant reduction in the effort in practice.

The method according to the present application for mounting a system according to the present application to a busbar 1 suspended at a distance from a ceiling has the following steps: a) the fixing clip 2 is fixed at different positions on the busbar 1 along the longitudinal axis L, and b) the

side profile parts

3,4 are connected to the fixing clip 2 by means of a snap connection.

Fig. 8 shows a schematic view of the bus bar system from above. In the example shown in the figures, the retaining clip 2 is further preferably designed such that, in the mounted state on the busbar 1, a distance a is formed between the busbar 1 and the

side profile parts

3,4, respectively, through which air can flow. This makes it possible to obtain: in the operating state, air can flow between the busbar 1 and the

side profile parts

3,4 and thus cooling of the busbar 1 takes place.

As shown in these figures, the two

side profile parts

3,4 do not touch each other in the mounted state on the busbar 1. This results in a difference from the prior art mentioned at the outset, by means of which a particularly effective cooling air circulation can be achieved. For example, it is provided that this can be the case: as shown in fig. 5, a distance a2 is formed between the upper end regions of the

side profile parts

3,4, which distance is greater than the horizontal transverse extension b of the busbar 1.

The

side profile parts

3,4 can in principle be designed with different cross-sectional shapes and sizes. It is advantageous in terms of production technology if the

side profile parts

3,4 are preferably mirror-symmetrically shaped.

The

side profile parts

3,4 are preferably shaped in such a way that, in the mounted state on the busbar 1, they project downwards beyond the busbar 1. It is thus possible to obtain: in the operating situation, the busbar 1 and, if necessary, the lamp or the like mounted on the busbar are virtually invisible when viewed obliquely from below. For example, it is provided that this can be the case: as shown in fig. 5, the

side profile parts

3,4 project downwards beyond the busbar 1 to the extent of a dimension u which is at least equal to half the vertical extension h of the busbar 1, preferably at least equal to the vertical extension h of the busbar 1.

The upward projection amount can be similarly set. It is thus possible, for example, to cover the fastening of the cable mount to the busbar 1.

It has proven to be advantageous if the retaining clip 2 is made of plastic and/or the

side profile parts

3,4 are made of aluminum. The retaining clip 2 can be formed, for example, by injection molding. The

side profile parts

3,4 can be designed, for example, as aluminum extruded profiles.
