It is fixed via a screw 20d so as to protrude toward the surface (see FIG. 8). Between the left and right lower pieces 20c, a chain receiver 21 having an upper opening is attached via a screw 21a (see FIG. 9). In this embodiment, the chain receiver 21 constitutes the “fixed side fixture” of the present invention.

  Reference numeral 22 denotes a long chain (corresponding to the “curved chain” of the present invention), which is formed by connecting a square cylindrical chain body 22a in a series in a swingable manner. , One end (lower end) 22b is fixed to the chain receiver 21 via a screw 21b, the middle part is curved upward, and the other end (upper end) 22c is connected to the upper piece 18c of the first mounting bracket 18. An upper piece 23b protruding to the indoor side of the second fixture 23 is fixed to the second fixture 23 fixed via the screw 18d, and the “movable side fixture” of the present invention is used. It is composed. Reference numeral 24 denotes a lead wire for supplying commercial power. The lead wire 24 is, for example, one that is drawn into one end of the chain receiver 21 and that reaches the chain one end 22b in a state where the chain receiver 21 is turned up. It is pulled out from the other end 22c of the chain through the inside and reaches the upper collar 2, and a coupler 24a provided at the end is connected to the coupler 6b on the lamp body side. The lead wire 6 a on the side of the lamp body 6 reaches the vertical hook 4 in a state of being divided into left and right by the upper hook 2 and is connected to the lamp body 6 at the vertical hook 4. On the other hand, the lead wire 24 drawn from the other end 22c of the chain is close to the transmission belt 16, and in this case, the lead wire 24 is bound to the transmission belt 16 by a binding member 26 such as a binding string or a binding band. Integration is planned.

As described above, when the door 1 moves left and right, the first and second fixtures 18, 23, the chain other end 22c, and the lead wire 24a drawn from the other end 22c are integrated with the door 1. As a result, the saddle-shaped intermediate portion of the chain 22 moves to the left and right together with the internal lead wire 24a.
Reference numeral 27 denotes a cover, and both right and left ends of the cover 27 are detachably fixed to the fourth fixture upper and lower pieces 20b and 20c via screws 27a.

In the embodiment of the present invention configured as described above, the drive belt 16 suspended between the drive sprocket 14 and the driven sprocket 15 is moved by the drive of the electric motor 13 built in the upper frame 10. The hanger roller 1c provided on the upper arm 2 of the door 1 via the bracket 1b rolls on the hanger rail 17, so that the door 1 moves left and right at the doorway. In connecting the lamp 6 for light display to the commercial power source side, the second fixture upper piece 23b that constitutes the movable fixture so as to project forward from the front surface where the upper frame 10 opens to the upper collar 2. The upper frame 10 is provided with a chain receiver 21 that constitutes a fixed-side fixture so as to protrude from the front surface of the upper frame 10 in a state of being positioned below the upper piece 23b. One end 22b is attached to the chain receiver 21, the other end 22c is attached to the second fixture upper piece 23b, and a lead wire 24 connected to a commercial power source is passed through the chain 22 to connect the couplers 6b and 24a to each other. Thus, the lamp body 6 is connected to a commercial power source.
When the other end 22c of the chain moves together with the door 1 as the door 1 moves left and right, the chain intermediate portion 22d that curves in a bowl shape is interlocked with the left and right relative movement of the other end 22c of the chain with respect to the one end 22b. Since the lead wires 24 are displaced to the left and right, the lead wires 24 are not forced to be deformed, and the life can be extended.
Moreover, since such a power supply device 12 can be easily attached to the existing upper frame 10 as a retrofit, there is no need to replace the upper frame with a new one, and the drive member such as the electric motor 13 is effectively used as it is. can do.

  In addition, the chain 22 is attached to the chain receiver 21 provided with one end 22b supported on both left and right ends of the upper frame 10, and the other end 22c is provided on the second attachment upper piece 23b provided on the upper collar 2. The intermediate portion 22d can be reliably supported on one end side (lower half portion) of the chain 22 in which the intermediate portion 22d is bent in a bowl shape, so that the chain intermediate portion 22d is stably displaced as the door body 1 opens and closes. The opening and closing movement of the body 1 is not impaired.

  In addition, the door 1 is an electric type that automatically opens and closes using the electric motor 13 and the transmission belt 16, but the second attachment 23 serving as a movable attachment includes the transmission belt 16 and the chain 22. Therefore, the space between the transmission belt 16 and the chain 22 can be used effectively to provide a wasteful arrangement structure.

  Further, in this case, since the lead wire 24 drawn from the upper end 22c of the chain 22 is bound to the transmission belt 16 via the binding member 26, the transmission belt 16 and the lead wire 24 are integrated. Since the movable side of the lead wire 24 moves together with the transmission belt 16 as well as the second mounting tool 23 on the movable side, inadvertent movement of the lead wire 24 is restricted, thereby the lead wire 24. Can be protected.

  Note that the present invention is not limited to the electric type, and can be implemented even by a manual type. Needless to say, the present invention can be implemented as a new one. Furthermore, in the present embodiment, the single-open type has been described, but it is needless to say that a double-open type may be used.

  INDUSTRIAL APPLICABILITY The present invention can be used in a door for a sliding door provided with an electrical component such as a lamp body, so that a power feeding device to the electrical component can be easily attached.
