As a result, the border cable 6 is electrically connected to the connector box 7. Is done. Furthermore, a connection terminal box 8 connected to the dimmer 21 is provided on the upper surface of the structure 1 (see FIG. 1), and the connector box 7 is connected to the connection terminal box 8 with a power cable (not shown). Has been. Accordingly, power is supplied to the border cable 6 in the cable storage means 5 and further to the power supply connector 61 via the dimmer 21, the connection terminal box 8, and the connector box 7.

  As shown in FIG. 1, the cable storage means 5 configured in this way is installed at a position corresponding to an electrical device attached at an arbitrary position of the elevating baton 2, for example, the branching device 9. The branching device 9 is detachably mounted on the elevating baton 2, has a power receiving connector 91 connected to the power feeding connector 61 of the border cable 6, and includes a plurality of outlets 92. The outlet 92 is connected to a lighting fixture such as a spotlight suspended from the lifting baton 2.

In the vicinity of each branching device 9 attached above the elevating baton 2, a cable locking means 10 is installed upright . As shown in FIG. 7A, the cable locking means 10 has an arm shape and includes a support leg portion 11 and a head portion 12 that is U-shaped in front view. A columnar locking rod 13 is provided between both side walls of the head 12 over both side walls.

  The connection process of the border cable 6 in the above configuration will be described. First, as shown in FIG. 3, an arbitrary lifting baton 2 to which a branching device 9 as an electric device is to be attached is lowered to near the floor surface, and the cable locking means 10 corresponds to the mounting position of each branching device 9. Is installed. This cable locking means 10 may be always fixed to the elevating baton 2 or may be attached to and detached from any elevating baton 2.

  From this state, as shown in FIG. 4, the elevating baton 2 is raised to the vicinity of the structure 1 made of a roof-like ceiling material. In this case, the head 12 of the cable locking means 10 is in a state of protruding to the upper surface side of the structure 1. Next, the cable storage means 5 is moved along the guide rail 4 to the vicinity of the cable locking means 10, the leading end side of the border cable 6, that is, the power feeding connector 61 side is pulled out from the cable storage means 5 by a predetermined length, Lock to the stop means 10. As shown in FIG. 7B, this locking is performed by passing the feeding connector 61 side of the cable 6 so as to wind the locking rod 13 and sandwiching the winding portion of the cable 6 with the clasp 14. This is done by wearing and fixing. Subsequently, the connection cable 51 led out from the cable storage means 5 is connected to the connector box 7.

  Next, as shown in FIG. 5, the elevating baton 2 is lowered to near the floor surface. At this time, a force is applied to the cable 6 in the direction in which the cable 6 is wound by the cable storage means 5, but the cable locking means 10 causes the cable 6 to have a predetermined length from the distal end side of the cable 6, that is, from the power feeding connector 61 side. Since this portion is locked, the force is received by the locking portion and does not reach the power feeding connector 61. And the branching device 9 is attached on the raising / lowering baton 2, and the power feeding connector 61 of the cable 6 and the power receiving connector 91 of the branching device 9 are connected. As shown in FIG. 6, with this connection completed, a lighting fixture (not shown) is suspended from the lifting baton 2 and connected to an outlet 92 of the branching device 9.

  In such an installed state, the lifting baton 2 can be moved up and down. In this case, the cable 6 is wound up by the cable storage means 5 as the lift baton 2 is moved up and down, and is rewound and stored. Further, since the cable 6 is locked at a predetermined length from the power supply connector 61 side by the cable locking means 10, the lifting and lowering operation of the lifting baton 2 causes the connection portion between the power supply connector 61 and the power receiving connector 91 to be connected. The force in the direction of separating these does not act directly. Therefore, the cable locking means 10 has a function of locking the cable 6 stored in the cable storage means 5 in the initial stage above the structure 1 and then lowering it to near the floor surface to connect to the branching device 9 (see FIG. 5), and also has a function of preventing tension from acting on the connecting portion between the power feeding connector 61 and the power receiving connector 91.

  In the above description, the branching device 9 is described as an example of the electric device. However, the lighting apparatus may be directly connected to the cable 6 as the electric device without passing through the branching device 9.

  As described above, according to the present embodiment, an electric device can be attached to an arbitrary lifting baton 2, so that an optimum lighting effect can be obtained from an optimum position in accordance with the contents of the production, and illumination with high performance. It can be performed. Further, in this case, the connection and storage processing of the cable 6 can be performed smoothly. Furthermore, since the cable 6 is locked by the cable locking means 10, the power feeding connector 61 is accompanied with the lifting operation of the lifting baton 2. It is possible to avoid the tension from acting on the connection portion between the power receiving connector 91 and the power receiving connector 91, and the connection state of the connection portion can be reliably maintained.

In the present embodiment, among the plurality of guide rails 4 laid on the upper surface of the structure 1, the cable housing means 5a for housing the dimming signal cable 6a is installed on one rail, and the other cable housing means. In 5b, the power cable 6b is accommodated. Therefore, the dimming control signal is sent to the outlet box 7a corresponding to the cable storage means 5a, and the power supply voltage is supplied to the outlet box 7b corresponding to the cable storage means 5b.

  As shown in FIG. 9, a branching device 9a and a small dimmer 21a are mounted on the lift baton 2 at positions corresponding to the cable storage means 5a. The signal line from the branching device 9a is connected to the dimmer 21a. On the other hand, a power source line is connected to the dimmer 21a from the branching device 9b to which power is supplied, and power is supplied from the dimmer 21a to the lighting fixture L suspended from the elevating baton 2. Therefore, in this embodiment, the branching devices 9a and 9b and the dimmer 21a correspond to the electrical devices. The electric device may be, for example, a smoke device that can be attached to the elevating baton 2 and requires a power source and generates smoke for production. Further, the dimming control signal may be transmitted wirelessly, and in this case, the cable housing means 5a can be omitted.

  As described above, according to the present embodiment, in addition to the same effects as those of the first embodiment, cable processing of the signal cable 6a and the power cable 6b can be performed smoothly. Further, as an electric device, any device that requires a power source can be applied.

  The present invention is not limited to the configuration of each of the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, the cable locking means 10 has only a function of locking the cable 6 stored in the cable storage means 5 in the initial stage above the structure 1 and then lowering it to near the floor surface and connecting it to the branching device 9. You may comprise as follows. That is, in order to connect the cable 6 to the branching device 9, the lifting baton 2 is raised to the vicinity of the structure 1 (see FIG. 4). Here, the cable 6 is temporarily fixed to the cable locking means 10, and in this state, the lifting baton 2 is lowered to lower the cable 6 to near the floor (see FIG. 5) and connected to the branching device 9, after which the temporary fixing is released, and tension is applied to the connecting portion between the power feeding connector 61 and the power receiving connector 91. The function that is not allowed may be dealt with by the configuration on the branching device 9 side. In particular, when the force is not applied to the cable storage means 5 in the direction in which the cable 6 is always wound, such a configuration is sufficient.

  Although it is preferable to lay the guide rail 4 on the upper surface of the structure 1 as in the above-described embodiment, the guide rail 4 is configured so that one cable storage means 5 fixedly installed on the guide rail 4 is stored in the other cable storage. More preferably, a bypass rail is provided so that the means 5 can be detoured and moved. The guide rail 4 is not necessarily required as long as it is movable on the upper side of the structure 1. For example, the cable storage means 5 may be suspended from the ceiling surface of a building structure provided above the structure 1 so that the cable storage means 5 can be moved along the ceiling surface. You may arrange | position so that the body 1 can be attached or detached.
