Arrangement for installing luminaires -Arrangemang för montering av belysningsarmaturer

The present invention is directed to an arrangement for mounting a series of multiple luminaires.

Luminaires in industrial buildings are usually installed above work machines or in other awkward places. Cranes or other lifting equipment are needed to be able to service them. Solutions are known in which a steel rope is attached to the luminaire, by means of which the luminaire can be taken down for maintenance. However, such an arrangement is not advantageous if the luminaire is located above the working machine.

The object of the invention is to facilitate the maintenance and cleaning of luminaires.

This is achieved by an arrangement according to the invention, characterized in that it comprises a carriage for each lamp, a rail on which said carriages are movably arranged, two rope reels, at least one of which is provided with a drive, a first rope running from one reel to another and connected to a service station with respect to the last wagon, wherein the movement of the rope causes the wagon to move from one end station to another, i.e. from its operating position to its service station or vice versa, a second rope attached to the first and last wagons connecting successive wagons so that the last wagon moves to its operating position by the first rope pulls the wagons following it in the direction of travel to an operating position where all the wagons are at a certain distance from each other.

By means of the invention, the luminaires can be moved from their normal operating position to a position where they can be easily and safely maintained in accordance with safety regulations without the need for cranes. The installation of the luminaires according to the invention is also economically advantageous.

Some preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a side view of an arrangement of two luminaires in their operating position, Figure 2 shows a side view of luminaires in their service station, Figure 3 is an enlarged side view of the luminaire shown in Figure 1, Figure 4 is a cross-section; Fig. 5 shows a side view of an alternative arrangement with two luminaires in their operating position, Fig. 6 shows a side view of said luminaires in their service station, Fig. 7 is an enlarged side view of the luminaire shown in Fig. 5, and Fig. 8 is a cross-section along the line AA in Fig. 7.

In the figures, reference numeral 1 denotes a horizontal rail suspended from the ceiling of a building. The luminaire, which comprises a choke housing 2, a reflector part 3 and a distribution box 4, is mounted on a frame 5 to which a series of wheels 6 is attached. The frame and the wheels form a carriage for the luminaire. The wheels 6 are arranged in a channel 7 of the rail 1, which is formed by two flanges 8 and along which the wheels can move guided by the side walls of the channel.

Several luminaires can be mounted on the same rail, two of which are shown in the figures. The distribution boxes of the luminaires are electrically connected to each other and to the mains voltage by means of electrical wires 9. Cable 10 is the connection cable of the luminaire. The rope 11, which runs to the supply line from the last carriage 12 to the socket 13 and is fastened to the supply line, is fastened to the carriage body by means of fasteners 14.

In the embodiment of the invention shown in Figures 1-4, the second rope 15, which is attached only to the carriage 12, runs in an end loop from the rope reel 16 to the rope reel 17. When the lamps have to be moved to their service station close to each other, cf. Fig. 2, the spool 17 rotates clockwise by means of a palm 18, whereby the rope 15 attached to the carriage 12 moves the carriage to the left. When the carriage 12 has reached the carriage directly in front of it, it starts to push this and thus causes all the carriages in front to move in the same direction. The movement of the wagons is continued until they reach the service station.

After maintenance, the wagons are returned to their operating position at a distance from each other, cf. Fig. 1, by rotating the spool 17 in the opposite direction, the rope 15 attached to the last carriage 12 moves the carriage to the right and then begins to pull all the carriages attached to each other by the rope 11 in the same direction until they are again in their original position a certain distance from each other.

In the embodiments shown in Figures 5-8, a rope 11 running along the electric line or a second rope 15 attached to the last carriage 12 passes from said carriage around the rope reel 16 and is then arranged to rotate around the rope reel 17.

When the luminaires need to be moved close to their service station, see Fig. 6, the carriages are towed by hand one by one by means of a rope 11 attached to the first carriage and connecting the carriages to the left. After maintenance, the carriages are returned to their operating position at a distance from each other, as shown in Figure 5, by rotating the spool with a crank 18, with the rope attached to the last carriage moving the carriage to the right and then moving all carriages until they are in their original positions again.

The embodiments according to Figures 1-4 and Figures 5-8 differ in practice in that in the former embodiment the luminaires are wound and retracted by a winding device to the service station, while in the latter embodiment the luminaires are manually retracted to the service location and the winding device is used only to return the luminaires.

The examples given above are not intended to limit the scope of the requirements.
