The opening / closing body is wound eccentrically in substantially the same radial direction over the width direction. Therefore, due to the eccentricity, there is a risk that vibration or noise when the opening and closing body is wound up or extended, the load of the winding device may increase, etc., according to the present invention, Since the electrical wiring is wound substantially spirally with the winding of the opening / closing body, it is possible to prevent the eccentricity in the substantially same radial direction over the width direction as described above, and to reduce vibrations and noises.

  Furthermore, according to the fourth invention, even if there is little or no light near the opening / closing body, it is possible to make a person who tries to pass through the passage easily visually instruct the passage method. As a result, it is possible to smooth the blame action in an emergency such as a fire or a power failure.

  Furthermore, according to the fifth aspect of the invention, the power to the display unit can be reduced to the necessary minimum.

Furthermore, according to the sixth invention, the electric wiring to the display unit can be made a simple structure that is substantially unrelated to the opening / closing operation of the door member.

  According to the display units 41, 42, 43, 44, and 45, the passer who wants to pass through the passage port 11a first follows the instructions of the display units 41, 42, 43, and 44 on the surface of the door member 12 to obtain the first sheet. The door member 12 is opened from the surface side. Then, immediately after opening the first door member 12, the passer-by visually observes the display unit 45 on the back surface of the two-sided door member 12 and follows the instructions of the display unit 45 for the second door member 12. Will be pushed open from the back side.

The display units 41, 42, 43, 44, and 45 are electrically connected to electrical wirings 51 and 52 for supplying power.
These electric wirings 51 and 52 are inclined along the opening / closing direction of the opening / closing body, and are fixed along one or both of the front and back surfaces of the opening / closing body 11.
Specifically, the electric wiring 51 is fixed to the upper part of the opening / closing body main body 11 with respect to the door member 12 so as to incline to one side in the opening / closing body width direction (leftward in the illustrated example). .
Further, the electric wiring 52 is fixed to the upper part of the opening / closing body main body 11 with respect to the door member 12 so as to incline to the other side in the opening / closing body width direction (rightward in the illustrated example).

And the load side of these electric wirings 51 and 52 is appropriately distributed in the vicinity of the door member 12 and wired so as to supply power to the display units 41, 42, 43, 44 and 45.
Further, the power supply sides of these electric wirings 51 and 52 are wired so that electric power is supplied from a control unit (not shown) in the winding device 30.

The control unit receives a detection signal from a sensor (not shown) that detects the fully closed state of the opening / closing body 10 and supplies power to the electrical wiring 51 and the electrical wiring 52 only when the opening / closing body 10 is fully closed. The circuit is configured to supply.
Further, when the display units 41, 42, 43, 44, and 45 are configured by the EL film as in the present embodiment, the power source needs to be a power source having a predetermined waveform adjusted to an appropriate voltage and frequency. Therefore, a waveform converter (for example, an inverter device) for obtaining this power source is electrically connected to the control unit.
The power supply to the waveform converter can be a commercial power source such as the power source of the winding device 30, but the display units 41, 42, 43, and 44 even in the event of a power failure due to a disaster or the like. , 45 is preferably a battery power source so that it can emit light.
The control unit may have a circuit configuration for lighting the display units 41, 42, 43, 44, and 45 via the waveform conversion device and the electrical wirings 51 and 52.

  Each guide rail 20 is a member that surrounds both sides of the opening / closing body 10 in the opening / closing body width direction in a substantially U-shaped cross section, and guides the opening / closing body 10 in the opening / closing direction.

The winding device 30 is a mechanism that rotates the winding shaft 31. The winding device 31 winds or unwinds the opening / closing body 10 by the winding shaft 31.
The winding device 30 includes a mechanism for rotating the winding shaft 31 by an electric drive source such as a motor, a mechanism for rotating the winding shaft 31 by a biasing force of a biasing member such as a spring, Any form such as a mechanism for rotating the take-up shaft 31 by its own weight or a combination of these mechanisms may be used, but the opening / closing body 10 is closed even in the event of a power failure due to a disaster or the like. It is preferable to use a mechanism that does not operate at least when the opening / closing body 10 is drawn out (for example, a mechanism using the biasing member, the weight body, or the weight of the opening / closing body 10).

Thus, according to the opening / closing device A, when the opening / closing body 10 is closed, the opening / closing body 10 in the closed position is detected by a sensor (not shown) and is connected via the electric wires 51, 52, etc. Electric power is supplied to the display units 41, 42, 43, 44, and 45 from a power source (not shown) on the control unit side.
Then, since the display units 41, 42, 43, 44, 45 emit light, the display units 41, 42, 43, 44, 45 even when there is no other light in the vicinity of the opening / closing body 10 or when there is little light. Can be clearly seen by a passerby or the like.
Further, when the opening / closing body 10 is opened, the power supply to the display units 41, 42, 43, 44, 45 is cut off by the control unit, so that the display units 41, 42, 43, 44, 45 are It stops emitting light.
During the opening operation, the electrical wires 51 and 52 are wound in a substantially spiral shape over substantially the entire length of the winding shaft 31 as the opening / closing body 10 is wound by the winding shaft 31. Therefore, the winding diameter of the opening / closing body 10 is not partially increased in the width direction, and the opening / closing body 10 is not eccentrically wound in the substantially same radial direction over the width direction. Vibration and noise at the time of rewinding and rewinding are relatively small.

The opening / closing device A is provided with the inclined electric wires 51 and 52 so as to extend over substantially the entire width of the opening / closing body, so that vibrations and noises during winding and rewinding as described above are provided. However, it is also possible to adopt a configuration in which both electric wirings 51 and 52 are provided only on one side in the opening / closing body width direction.
Also, one of the electric wires 51 and 52 is omitted, and one electric wire 51 (or 52) is distributed in the vicinity of the door member 12, or an electric wire other than the electric wires 51 and 52 is added. It is also possible to do.

Moreover, the said switching device A arrange | positions display part 41,42,43,43,44 on the surface of the door member 12, and the visibility, design property, etc. of these display parts 41,42,43,44 are favorable. Although it is a preferable example, it is good also as an aspect of the switchgear B mentioned later from a viewpoint which arrangement | positioning, a structure, etc. of the electric wiring 51,52 to the display parts 41,42,43,44 are not restrict | limited.
In this opening / closing device B, the display units 41, 42, 43, 43, 44 in the above-described opening / closing device A are arranged in parts other than the door member 12, and the electric wirings 52, 53 are connected to the left and right display units 43, It fixes so that it may go into the seat board member 13 from each of 43 (refer FIG. 4).

More specifically, the display units 41, 42, 43, 43, and 44 are arranged in a region around the passage opening 11 a in the opening / closing body main body 11 and in the vicinity of the door member 12.
Each electrical wiring 52 (or 53) has its load side connected to one display unit 43 and its power supply side connected to a control unit (not shown) in the seat plate member 13.
The control unit in the seat plate member 13 is a sensor that detects that the opening / closing body 10 is closed, and a circuit that supplies power to the display units 41, 42, 43, 43, 44 in accordance with a signal from the sensor. And a waveform converter such as an inverter, and a power source such as a battery.

According to this opening / closing device B, there is no restriction on the location and structure of the electric wires 51 and 52 in order to enable the door member 12 to be opened and closed.
That is, for example, according to the above-described opening / closing device A, the load side of the electric wirings 51 and 52 is on the upper end side of the door member 12 fixed to the opening / closing body 11 in order to enable the opening / closing operation of the door member 12. However, in the switchgear B, as shown in the illustrated example, the electrical wiring 51 and the electrical wiring 52 may be relatively short wirings between the display units 43 and 43 and the seat plate member 13. it can.
Further, according to the above-described opening / closing device A, the flexibility of the door member 12 is impaired by the display units 41, 42, 43, and 44, and the opening / closing operability of the door member 12 may be deteriorated. In the apparatus B, since the display units 41, 42, 43, and 44 are provided separately from the door member 12, the door member 12 flexes flexibly and its opening / closing operability is good.

Although the display unit 45 on the back side of the door member 12 is not shown in the opening / closing device B, the display unit 45 is disposed on the back side of the door member 12 like the opening / closing device A and is distributed from the front side. Electric power may be supplied by electric wiring (not shown).
In addition, the opening / closing device A and the opening / closing device B are provided on the back side of the door members 12 and 12 with the display portions 45 and 45 for instructing the push-opening operation.
