Description

[Detailed description of the device]

[0001]

[Detailed industrial description]

 The present invention relates to a lighting device used in a ceiling system or the like.

[0002]

[Prior Art]

 As is well known, this type of luminaire device is installed by using a ceiling frame (T bar) attached to the ceiling, and a pair of parallel side channels is attached to the ceiling frame by using a mounting bracket. The side channel is configured to support sockets, reflectors, ballasts, etc.

In such a lighting fixture, depending on its type, it may be required to install a louver, a panel, etc. below the reflector. At that time, the side channel is installed at a higher position than before, and the lighting fixture itself is raised to form a space below the reflector, and the louver is installed using this space.

As described above, in order to install the side channel at a high position, a bending edge is formed at the tip of a mounting bracket conventionally attached to the side channel, and the bending edge is engaged with the ceiling frame. The above is proposed (for example, see Japanese Utility Model Publication No. 3-32006). According to this, the mounting bracket should always be laid down sideways, and when the side channel is to be installed at a high position, the mounting bracket should be erected.

However, when such a mounting bracket is used, the mounting bracket can be fixed to the side channel and the ceiling frame each time the mounting bracket is laid down sideways or raised. is necessary. In addition, it is necessary to prepare the mounting metal fittings with the necessary structure for fixing them, which complicates the structure of the mounting metal fittings.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention aims to simplify the configuration required for changing the height of a side channel.

[0007]

[Means for Solving the Problems]

 According to the present invention, a pantograph is constituted by four arms, and an upper part of the pantograph is connected to a support fitting installed in a side channel, and a lower part is connected to a supporting fitting installed in a ceiling frame. And a plurality of pairs of holes along the longitudinal direction of the joint bar. A pair of holes arbitrarily selected from the plurality of pairs and both joints of the pantograph are provided. It is characterized in that it is formed by connecting parts.

[0008]

[Action]

 If each joint of the pantograph is connected to each pair of holes located on the outermost side of the connecting bar, the pantograph will be minimized and the side channels will be in the lowest position. If each joint part of the side channel is connected to each pair of holes located on the innermost side of the connecting bar, the side channel is extended to the maximum and the side channel is at the highest position. This allows the side channel to be installed at any height.

The joint parts of the pantograph are connected by a connecting bar. This locks the movement of the pantograph and restrains its expansion and contraction. This fixes the position of the side channels. Therefore, the work for fixing is not particularly required. Moreover, when changing the height, it is not necessary to change the mounting positions of the side channels and the mounting brackets for the ceiling frame.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a pair of ceiling frames (one ceiling frame is omitted in the figure), which are fixed so as to be suspended from the ceiling. Reference numeral 2 is an illuminating device, which is provided with a pair of parallel side channels 3 on which a socket base 4, a socket 5, a ballast 6, a reflector 7 and the like are supported. The above-mentioned configuration is not particularly different from a normal device of this type.

According to the present invention, the support fittings 8A and 8B are installed on the ceiling frame 1 and the side channels 3. It may be fixed or slidable. Reference numeral 9 denotes a pantograph, which is composed of four arms 10 to 13. The lower part of the pantograph 9, that is, one end of the arms 10 and 11 is rotatably connected to the support fitting 8A by using a pin or the like. Similarly, the upper portion, that is, one end of the arms 12 and 13 is rotatably connected to the support fitting 8B by using a pin or the like.

The pin 14 is inserted into one joint portion of the pantograph 9, that is, the connecting portion of the other ends of the arms 10 and 12, and the pin 15 is inserted into the other joint portion, that is, the other end of the arms 11 and 13. To do. By inserting the pins 14 and 15, the joints can be bent.

A connecting bar 16 connects both joints, and a plurality of pairs (three pairs in the illustrated example) of holes 17A, 17B to 19A, 19B are provided along the longitudinal direction thereof. The pins 14 and 15 can be selectively inserted into the respective holes, and can be rotated in the inserted state.

FIG. 1 shows a state in which the side channel 3 is at a certain height position, and in this case, as shown in detail in FIG. 3, the pins 14 and 15 are provided with holes 18 A and 18 B respectively in the connecting bar 16. Is inserted into. As can be understood from this state, the pantograph 9 joints are connected by the connecting bar 16. Therefore, the pantograph 9 is locked and its position is fixed. As a result, the side channel 3 is fixedly supported at a certain height position with respect to the ceiling frame 1.

When it is necessary to attach the side channel 3 to the lowest position, the pins 14 and 15 may be inserted into the outermost pair of holes 17A and 17B as shown in FIG. Similarly, when it is necessary to attach the side channel 3 to the highest position, the pins 14 and 15 may be inserted into the innermost pair of holes 19A and 19B as shown in FIG. FIG. 2 shows the state of the side channel 3 at that time.

When changing any of the height positions, it is not necessary to change the mounting state of the support fittings 8 and 9 to the ceiling frame 1 and the side channel 3. It suffices to simply select the pins 14 and 15 through a pair of holes provided in the connecting bar 16 and insert them, and the position of the side channel 3 is fixed by the insertion, and the operation is simple. It

1 and 2 show a state in which a pantograph is attached to only one side channel, and a pantograph for the other side channel is omitted. Although these figures show an example in which two pantographs are installed in the side channel, the number is not limited to two, and the number may be increased or decreased as necessary.

[0018]

[Effect of the device]

 As described in detail above, according to the present invention, it is extremely easy to change the height position of the side channel of the luminaire, and it is not necessary to attach it to the support fitting each time the change is made.
