The fastening unit 52 includes a bolt 52a, a locking nut 52b, a spring washer 52c, and a flat washer 52d.

  Next, how to use the above-described temporary lighting device 2 will be described.

  First, the mounting portion 4 is attached to the support 1. At this time, the first semicylindrical member 41 of the mounting portion 4 is placed so as to sandwich the support 1 as shown in FIG. 11, and the second semicylindrical member 42 is made to approach the first semicylindrical member 41. As a result, as shown in FIG. 10, the closed state is held by the lock unit 44 after both half-cylindrical members 41 and 42 are held in the closed state.

  Then, the illumination unit 3 is attached to the chuck plate 51 of the support unit 5. At this time, the fastening unit 52 is temporarily fixed in the bolt insertion hole 51a of the chuck plate 51, and the head of the bolt 52a of the fastening unit 52 is engaged with the guide rail 32 of the lighting unit 3 51 is positioned so as to be disposed substantially at the central position in the longitudinal direction of the illumination unit 3, and the lock nut 52b is fully tightened to the bolt 52a via the spring washer 52c and the flat washer 52d. The lighting unit 3 is fixed.

  Thereafter, after the receiving portion 45 of the mounting portion 4 fixed to the support 1 as described above is properly inclined, the base end side of the supporting portion 5 to which the lighting portion 3 is attached as described above is the mounting portion 4 Insert into the receiver 45.

  Then, the power supply cable 6 of the lighting unit 3 is connected to the cable 8 a of the power supply 8. When one temporary lighting device 2 is used, the cable 8a of the power supply 8 is made to extend along the tip end of the support 1 and the support 5, and the tip end of the power cable 6 is a hanging member By suspending the chuck plate 51 of the support portion 5 at 9, the power cable 6 and the cable 8 a of the power supply 8 are prevented from hanging down and becoming an obstacle. In addition, when the connecting cable 7 of the lighting unit 3 is not used, the leading end side of the connecting cable 7 can be bundled by the tape 10 so that it does not hang down and get in the way.

  Here, as shown in FIG. 4, even when the inner cylinder is pulled out from the outer cylinder of the support unit 5 by a small number, the illumination unit 3 is disposed at a position away from the column 1 and at a high position. . However, as shown in FIG. 3, when all the inner cylinders are pulled out from the outer cylinder of the support portion 5, the lighting portion 3 is further away from the support 1 and higher than in FIG. 4. Will be placed in Thus, by changing the number of pulling out the inner cylinder from the outer cylinder, it becomes possible to adjust the total length dimension of the support portion 5 arbitrarily.

  In the installation state shown in FIG. 3, the shadow of the worker or the article is formed almost directly below, so that the shadow does not easily overlap the work place. On the other hand, in the installation state shown in FIG. 4, light is emitted obliquely downward from the illumination unit 3, so when another worker or an article is located in the middle of the light, those shadows may overlap with the work place It can happen.

  From this, it can be said that the installation state shown in FIG. 3 is easier to work than the installation state shown in FIG.

  In addition, after one temporary lighting device 2 is installed on the support column 1 as described above, for example, as shown in FIG. 5, the temporary lighting device 2 is connected to the existing temporary lighting device 2 so that other temporary lighting devices 2 are arranged side by side. can do.

  At this time, it is only necessary to connect the connector 6a of the power cable 6 of the other temporary lighting device 2 to the connector 7a of the connecting cable 7 of the existing temporary lighting device 2. If the power supply cable 6 and the connection cable 7 are in a hanging state, the connector 6a of the power supply cable 6 and the connector 7a of the connection cable 7 can be disposed at a position where the operator can reach, both connectors 6a and 7a. It is possible to relatively easily connect and disconnect the

  By the way, when removing the temporary installation illuminating device 2 installed as mentioned above, what is necessary is just to reverse the above-mentioned operation | work.

  As described above, according to the embodiment to which the present invention is applied, for example, the lighting unit 3 is installed at a position separated from and higher than the position of the mounting unit 4 by using the support 1 as an existing facility. Configured.

  As a result, unlike the Patent Document 2 described above, a support device such as a tripod is not required. Therefore, although the configuration is simpler than the Patent Document 2, the lighting unit 3 is located at a distance from the mounting unit 4 and It becomes possible to set it to a high position. Moreover, since the long illumination part 3 is used, compared with the said patent document 1, it becomes possible to illuminate a wide range.

  In particular, if the support 1 as the existing installation is a support installed at regular intervals, for example, in the vicinity of a railway track, and the temporary lighting device 2 according to the present invention is attached to this support, the railway track is used. Since it becomes possible to illuminate the track from a high position that does not interfere with the inspection and repair workers, the inspection and repair work can be performed efficiently.

  Further, in the above embodiment, by setting the total length dimensions of the outer cylinder and the inner cylinder of the support portion 5 as short as possible, the support portion 5 to which the illumination portion 3 is attached is attached to the attachment portion 4. However, since the expansion and contraction operation of the support portion 5 can be performed at a position where it can be reached, the expansion and contraction operation can be performed relatively easily.

  Further, in the above embodiment, since the flexible power cable 6 is provided to the lighting unit 3 so as to fly out from the light source unit 31, the power cable 6 can be easily attached to the power source 8. Furthermore, in the above embodiment, since the flexible connection cable 7 is provided to the lighting unit 3 so as to fly out from the light source unit 31, the temporary lighting device 2 is connected to the temporary lighting device 2 of the other same specification by the connecting cable 7. It becomes easy to connect. This makes it possible to illuminate a wide area as much as possible with a large number of temporary lighting devices 2.

  Further, in the above embodiment, the first semi-cylindrical member 41 and the second semi-cylindrical member 42 constituting the mounting portion 4 are attached so as to sandwich the post 1 as the existing equipment. The mounting operation of the mounting portion 4 can be performed relatively easily.

  In the above embodiment, the base end of the round rod-like support 5 is specified to be inserted into the bottomed cylindrical receiving part 45, and the attachment posture of the support 5 with respect to the attachment 4 is diversified. Since the change can be made, it becomes possible to quickly and easily attach the support portion 5 to the attachment portion 4, and at the same time, the arrangement of the illumination portion 3 can be arbitrarily selected, and the usability is improved.

  In addition, this invention is not limited only to the said embodiment, It is possible to change suitably within the range of a claim, and the range equivalent to the said range.
