For this reason, the normally open door body fully open holding state canceling means is a second release for inputting a second release signal for canceling the door body fully open holding state by the door body fully open holding means to the door body fully open holding means. It is a signal input means.

  In the present invention, as described above, when the door body is rotatable about the rotation axis, when the door body in the closing operation reaches the fully closed position, the door body opens. The door body stops in a fully closed state by abutting against a door contact such as a step of the upper door frame body.

  The opening / closing rotation angle of the door body, that is, the rotation angle from the fully open position to the fully closed position of the door body is arbitrary, for example, 90 degrees, 180 degrees, 270 degrees, An arbitrary angle may be used instead of such an angle of 90 degrees.

  In the above invention, the opening / closing body may be composed of only one door body, may be composed of one door body and one shutter curtain, and may be composed of one door body. It may be composed of a plurality of shutter curtains, may be composed of a plurality of door bodies and one shutter curtain, and is composed of a plurality of door bodies and a plurality of shutter curtains. It may be a thing.

  In the present invention, when the opening / closing body includes at least one door body and at least one shutter curtain, the arrangement positions of these door bodies and the shutter curtain are arbitrary. For example, the shutter curtain is arranged adjacent to the door body in the width direction of the door body (in other words, the shutter curtain width direction and the width direction of the door body are aligned in the same direction. May be disposed at a right angle to the door body (in other words, disposed such that the width direction of the shutter curtain and the width direction of the door body are orthogonal to each other). And when there are a plurality of door bodies, they may be combined.

  In addition, when the shutter curtain is arranged adjacent to the door body in the width direction as described above, the shutter curtain is adjacent to the shutter curtain at both ends in the width direction of the door body. At the end of the shutter curtain, when the shutter curtain is opened and closed, a guide section for guiding the edge of the shutter curtain in the width direction adjacent to the door is adjacent to the width of the door curtain. You may make it form over substantially the full length direction which is a direction orthogonal to a direction. According to this, a guide member (guide member) for guiding the opening / closing operation (opening / closing movement) of the shutter curtain becomes unnecessary.

  In addition, when the shutter curtain is arranged at a right angle to the door body as described above, the surface on the side facing the end in the width direction of the shutter curtain on the front and back surfaces of the door body. In the opening / closing operation of the shutter curtain, the guide portion for guiding the end portion on the side facing the door body of the both ends in the width direction of the shutter curtain is perpendicular to the width direction of the door body. It may be formed over substantially the entire length in the length direction. According to this, a guide member for guiding the opening / closing operation of the shutter curtain becomes unnecessary.

  In the present invention, when the opening / closing body includes at least one door body and at least one shutter curtain, the door body and the shutter curtain are interlocked to open / close ( An opening / closing control means for performing an opening operation and / or a closing operation may or may not be provided.

  According to the former case, the opening / closing operation of the opening / closing body including at least one door body and at least one shutter curtain can be smoothly performed. In the latter case, for example, at least one door body and at least one shutter curtain are always manually opened and closed.

  In the present invention, the opening / closing operation direction (opening / closing movement direction) of the shutter curtain may be the vertical direction, the horizontal direction, or a direction having an inclination angle with respect to these directions.

  In the present invention, as an example of the case where it is necessary to provide the above-described opening / closing control means, the opening / closing operation direction of the shutter curtain is the vertical direction and the downward direction is the closing operation direction, and the width direction of the door body (in other words, , In the left and right direction), a guide portion for guiding the opening and closing operation of the shutter curtain is formed over the entire length direction (in other words, the up and down direction) which is a direction orthogonal to the width direction. The case can be mentioned.

  In this example, since the shutter curtain cannot be closed until the door body is closed to the fully closed position, the opening / closing control means starts the shutter curtain closing operation after the door body is closed to the fully closed position. The control is executed, and the control for starting the opening operation of the door body after the shutter curtain is opened to the fully opened position is executed.

  In addition, when the guide part for guiding the opening / closing operation of the shutter curtain is not formed at the end part in the width direction of the door body, both ends in the width direction of the shutter curtain are provided between the shutter curtain and the door body. It is necessary to erect a guide member (so-called middle pillar) for guiding the end of the portion adjacent to the door body. In this case, the opening / closing operation of the shutter curtain can be performed independently of the opening / closing operation of the door body, and the opening / closing order of the shutter curtain and the door body is arbitrary. That is, the shutter curtain opening operation (closing operation) can be performed independently of the door body opening operation (closing operation).

  In the present invention, the door body obstacle sensing means for sensing an obstacle present in the movement direction of the door body during at least the closing operation during the closing operation and the opening operation of the door body is provided. May be.

  Here, the form and structure of the door obstacle detection means are arbitrary.

  The sensor 18 detects smoke and / or heat generated in the event of an emergency such as a fire, and inputs a disaster prevention signal BS (DC 24 V) to the interlock repeater 130.

  The disaster prevention center operation panel 19 is operated by a person at the disaster prevention center in the event of an emergency such as a fire, and inputs a disaster prevention signal BS (DC 24V) to the interlocking repeater 130 in the same manner as the sensor 18. Is.

  In the event of an emergency such as a fire, a disaster prevention signal BS from the sensor 18 or the disaster prevention center operation panel 19 is relayed by the interlocking repeater 130 and input to the door body automatic closing device 241. As a result, the brake 212 of the door opening and closing machine 210 is released, and the door 2 that has been fully opened is urged by the spring force accumulated in the torsion coil spring 16 and starts the closing operation. Further, when the [close] switch 119C of the door body opening / closing operation unit 20 is operated (pressed) in a normal state, the close signal (close operation instruction signal) from the [close] switch 119C is relayed by the interlocking relay 130. The operation signal (DC 24 V) is input to the door automatic closing device 241. As a result, the brake 212 of the door opening and closing machine 210 is released, and the door 2 that has been fully opened is urged by the spring force accumulated in the torsion coil spring 16 and starts the closing operation.

  In the present embodiment, as described above, the opening operation of the door body 2 is performed by the driving force of the motor 211 of the door body opening / closing device 210. That is, the opening operation of the door body 2 is performed electrically. When the door 2 that has been opened has reached the fully open position, the open limit switch of the open / close limit switch 240 is activated (ON), and the motor 211 is stopped and braked by the door switch control panel 242. 212 is restored. As a result, the drive shaft 140 of the motor 211 of the door opening / closing device 210 does not rotate due to the braking force of the brake 212 of the door opening / closing device 210. The shaft portion 226 </ b> A of the second bevel gear 226 transmitted by the rotation does not rotate. As a result, the rotation of the door body 2 is prevented. Thus, the fully open state of the door body 2 is held by the brake 212 of the door body opening / closing device 210.

  For this reason, in this embodiment, the brake 212 of the door opening and closing machine 210 is a door body fully open holding means for holding the door body 2 in a fully opened state. The brake 212 of the door opening / closing device 210 serves as a rotation shaft rotation preventing means for preventing the rotation of the shaft portion 226A of the second bevel gear 226 that is the rotation shaft of the door body 2. .

  As described above, FIG. 6 is a cross-sectional view showing the internal structure of the door opening and closing device 210. In FIG. 6, the left side portion of the door opening / closing device 210 is partially omitted (simplified). As shown in FIG. 6, the door opening / closing device 210 includes a DC or AC motor 211 and a brake 212 arranged in parallel in the axial direction.

The brake shaft 142 is coupled to a brake shoe 141 and a brake drum 143 that faces in the axial direction. The brake shaft 142 and the brake drum 143 in the normal state are pressed toward the motor 211 by the spring 144, and therefore the brake 212 is turned on (returned) by the pressure contact between the brake shoe 141 and the brake drum 143. . Therefore, the drive shaft 140 of the motor 211 at this time is not rotated by the braking force of the brake 212.

  On the other hand, when the solenoid 145 arranged in the brake 212 is energized by the power (release power) supplied from the door switch control panel 242, the brake shaft 142 and the brake drum 143 are generated by the magnetic force of the solenoid 145. Slides away from the motor 211 against the spring 144. Therefore, the pressure contact between the brake shoe 141 and the brake drum 143 is released, and the brake 212 is turned off (released state). Therefore, at this time, the drive shaft 140 of the motor 211 can be rotated by energizing the coil 146 with electric power (driving power) supplied from the door body switch control panel 242.

  Further, as shown in FIG. 6, a lever member 147 is disposed at the end of the brake shaft 142 opposite to the motor 211 side.

  As described above, the first slide member 150 is disposed below the second slide member 155 in the machine casing 149, and as shown in FIGS. The first bent portion 158A of the third member 158 constituting the two slide member 155 is disposed so as to face and contact the first bent portion 153A of the second member 153 constituting the first slide member 150 from the rear. .

  FIG. 13 is a diagram showing only the first slide member 150, the second slide member 155, the bending lever member 165 and the like which will be described later in detail, which are shown in FIG.

  As shown in FIG. 7, a solenoid 170 is attached to the bottom 149 </ b> A of the machine casing 149 of the door body automatic closing device 241, and the spring force of the spring 172 is applied to the plunger 171 of the solenoid 170. The plunger 171 always acts in the direction in which the plunger 171 protrudes from the solenoid 170. As shown in FIGS. 7 and 8, a locked member 173 bent in a substantially U-shape is connected to the tip of the plunger 171. The locked member 173 rotates around the central shaft 165A. One end of a substantially L-shaped bending lever member 165 (see also FIG. 13) that is movable is locked. As shown in FIGS. 7 and 8, a roller 166 is rotatably provided at the other end of the bending lever member 165 serving as a trigger lever member.

  As shown in FIGS. 7 and 13, the concave portion 151 </ b> B described above is formed in the portion of the first slide member 150 that faces the roller 166. Further, the automatic closing device 241 for doors is provided with a spring 167 for applying a turning force in the G direction around the central axis 165A to the bending lever member 165, and one end of the spring 167 is The bent lever member 165 is locked to the rising portion 165B, and the other end of the spring 167 is locked to a locking member 168 provided on the bottom portion 149A of the machine frame 149.

  As shown in FIGS. 7 and 8, the automatic closing device 241 for doors includes a micro switch 180 that operates when the bending lever member 165 rotates in the G direction around the central axis 165A. A micro switch 181 is provided which operates when the second slide member 155 slides in the direction of arrow D.

  The micro switch 180 is disposed so that an actuator 180A as an operating member can come into contact with a rising portion 165B of a bending lever member 165 that rotates in a G direction around a central axis 165A, and the micro switch 181 operates. The actuator 181A as a member is disposed so as to be able to contact the lower surface of the horizontal portion 158C of the second slide member 158 that slides in the arrow D direction.

  Next, the operation of the door automatic closing device 241 in the event of an emergency such as the occurrence of a fire will be described. As shown in FIG. 5, when a disaster prevention signal BS (DC 24V) is input from the sensor 18 or the disaster prevention center operation panel 19 to the interlock repeater 130 in an emergency such as the occurrence of a fire, the interlock repeater 130 is used for the door body. An operation signal (DC 24 V), which is a control signal, is input to a brake control circuit (not shown) of the automatic closing device 241. The DC motor 161 of the door automatic closing device 241 is positively driven by the input of this operation signal, and the pinion 162 attached to the drive shaft 161A of the DC motor 161 starts to rotate in the direction of arrow E shown in FIG. To do. Thereby, the second slide member 155 having the rack portion 157A meshing with the pinion 162 slides in the direction of arrow D shown in FIG.

  As described above, the first bent portion 158A of the third member 158 constituting the second slide member 155 is located behind the first bent portion 153A of the second member 153 constituting the first slide member 150. It arrange | positions so that the part 153A may be opposedly contacted.

  For this reason, when the second slide member 155 slides in the arrow D direction, the first bent portion 153A of the second slide member 155 pushes the first bent portion 153A of the first slide member 150 in the arrow D direction from the rear. become. Thereby, the first slide member 150 slides in the direction of arrow D together with the second slide member 155.

  FIG. 14 is a view showing a state in which the first slide member 150 shown in FIG. 7 slides in the direction of arrow D to the position where the brake 212 of the door opening and closing machine 210 is released together with the second slide member 155. is there. Also. FIG. 15 is a diagram showing only the first slide member 150, the second slide member 155, the bending lever member 165, the springs 164, 167 and the like shown in FIG.

  As the first slide member 150 and the second slide member 155 slide to the position shown in FIG. 14, the operating member 152 provided at the front end of the first slide member 150 is moved as shown in FIG. 6. Since the first portion 147A of the lever member 147 of the door opening and closing device 210 is pressed in the direction C in FIG. 6 via the operating member 148, the first portion 147A is the second bent portion of the lever member 147 as described above. It swings in the C direction with the portion 147D as a fulcrum. As a result, the brake shaft 142 and the brake drum 143 of the brake 212 of the door opening / closing device 210 slide in the C ′ direction, which is the same direction as the C direction, and thus have been turned on (returned) until then. The brake 212 is turned off (released state).

  As a result, the drive shaft 140 of the motor 211 of the door opening and closing device 210 is in a freely rotating state, and the shaft of the second bevel gear 226 to which the rotational force of the drive shaft 140 of the motor 211 is transmitted by the drive force transmission means. The part 226A is also in a free rotating state.

  For this reason, the door body 2 that has been fully opened starts a closing operation that rotates in the direction of arrow A shown in FIG. 1 by the spring force accumulated in the torsion coil spring 16. The closing operation is performed until the closing limit (closing operation limit) of the opening / closing limit switch 240 is activated (ON).

  When the first slide member 150 and the second slide member 155 slide to the position shown in FIG. 14, the bending lever member 165 rotates in the arrow G direction (see FIGS. 7 and 13) by the spring force of the spring 167. Then, the roller 166 of the bending lever member 165 engages with the concave portion 151 </ b> B of the first slide member 150. Thus, the first slide member 150 is prevented from moving backward, and the operating member 152 provided at the front end of the first slide member 150 is connected to the door body via the operated member 148 shown in FIG. The state in which the first portion 147A of the lever member 147 of the switch 210 is pressed in the direction C in FIG. 6 is continued. That is, the brake 212 of the door opening and closing device 210 is kept off (released).

  Further, the bending lever member 165 is rotated in the arrow G direction by the spring force of the spring 167, and the roller 166 of the bending lever member 165 is engaged with the recess 151B of the first slide member 510, as shown in FIG. As described above, the rising portion 165B of the bending lever member 165 presses the actuator 180A of the microswitch 180, so that the microswitch 180 is activated. As a result, an operation confirmation signal for the brake 212 of the door switch 210 is input to the interlocking relay 130 from a brake control device (not shown) provided in the door automatic closing device 241. Further, by the operation of the micro switch 180, a circuit for stopping the driving of the DC motor 161 is generated in the brake control device, whereby the positive driving of the DC motor 161 is stopped.

  Further, as the first slide member 150 slides in the direction of the arrow D (see FIG. 7), the lower surface of the horizontal portion 158C of the second slide member 155 is moved toward the micro switch 181 as shown in FIGS. In order to press the actuator 181A, the micro switch 181 operates. As a result, a circuit for reversely driving the DC motor 161 is generated in the brake control device. In order to generate this circuit, a micro switch 182 in which the actuator 182A is pressed against the side surface of the second bent portion 153B of the second member 153 of the first slide member 150 shown in FIG. 14 may be used. .

  Thereafter, by the reverse drive of the DC motor 161, the second slide member 155 slides in the direction opposite to the direction of the arrow D. However, the operation of the microswitch 181 is stopped by this slide, so the reverse drive of the DC motor 161 is Stop. As a result, the second slide member 155 that has been slid stops at the original position.

  As described above, the second slide member 155 returns to the original position shown in FIG. 7, but the first slide member 150 is shown in FIG. 7 because the roller 166 of the bending lever member 165 is engaged as described above. 14, the brake 212 of the door opening / closing switch 210 is kept off (released).

  During the closing operation of the door body 2, there is an obstacle in the closing operation direction of the door body 2, and when this obstacle is detected by the infrared sensor type door body obstacle detection device 133, this door An obstacle sensing signal from the body obstacle sensing device 133 is input to the interlocking repeater 130. As a result, an operation signal for operating (exciting) the solenoid 170 is input from the interlock repeater 130 to the DC solenoid 170 of the automatic closing device 241 for doors. As a result, since the solenoid 170 is excited and the plunger 171 is attracted, the bending lever member 165 whose one end is locked to the locked member 173 connected to the tip of the plunger 171 is shown in FIG. It rotates in the direction opposite to the arrow G direction shown in FIG.

  As a result, the roller 166 of the bending lever member 165 that has been engaged with the concave portion 151B of the first slide member 150 is detached from the concave portion 151B. For this reason, the first slide member 150 that has been prevented from retreating by engagement with the roller 166 slides to the original position by the spring force accumulated in the spring 164.

  As a result, the operating member 152 provided at the front end of the first slide member 150 moves the first portion 147A of the lever member 147 of the door opening / closing device 210 via the operated member 148 shown in FIG. The state of pressing in the direction C in FIG. 6 is released. As a result, the brake 212 that has been turned off (released) until then is turned on (returned), so that free rotation of the drive shaft 140 of the door opening / closing device 210 is prevented, and the drive force transmission means 230 is used. Thus, free rotation of the shaft portion 226A of the second bevel gear 226 connected to the drive shaft 140 is also prevented. As a result, the closing operation of the door body 2 that is in contact with or is likely to contact the obstacle is stopped.

  Note that when the obstacle is removed from the stopped door 2, the input of the obstacle detection signal from the door obstacle detection device 133 to the interlock repeater 130 is stopped. After the elapse of time, an operation signal for reactivating the door body automatic closing device 241 (for releasing the brake 212 again) will be input from the interlock repeater 130 to the door body automatic closing device 241. It may be.

  When the door body 2 in the closing operation reaches the fully closed position, the door body fully closed detection switch 82 is operated, and a fully closed signal is input from the door body fully closed detection switch 82 to the interlocking relay 130. Accordingly, the solenoid 170 is operated (excited) from the interlock repeater 130 to the DC solenoid 170 of the door automatic closing device 241 as in the case where the obstacle is detected by the door obstacle detecting device 133. An operation signal is input. As a result, the brake 212 that has been turned off (released) until then is turned on (returned), so that free rotation of the drive shaft 140 of the door opening / closing device 210 is prevented, and the drive force transmission means 230 is used. Thus, free rotation of the shaft portion 226A of the second bevel gear 226 connected to the drive shaft 140 is also prevented. As a result, the closing operation of the door body 2 is stopped. That is, the fully closed state of the door body 2 is maintained.

  The interlock repeater 130 is predetermined when a fully-closed signal is input from the door-body fully-closed detection switch 82 provided in the door stop portion 6C that comes into contact when the door body 2 reaches the fully-closed position. After a lapse of time, an operation signal may be input to the DC solenoid 170 of the automatic closing device for a door 241 so that the brake 212 is turned on. According to this, it is possible to prevent the brake 212 from being turned on immediately before the door body 2 is fully closed due to an error in the operation timing of the door body fully-closed detection switch 82. It is not necessary to decide strictly.

  On the other hand, in order to close the door 5 with the door 2 and to perform the closing operation of the door 2 held in the fully open state in order to test the opening / closing operation of the door 2 in the normal state, control is performed. A person such as a person operates (presses) the [close] switch 20 </ b> C of the door opening / closing operation unit 20.

Control of the operation, control of the restoration operation to the automatic closing device 241 for the door body when an obstacle is detected during the closing operation of the door body 2, and control for closing the door body 2 and the shutter curtain 101 in this order. Control to perform the opening operation of the shutter curtain 101 and the door body 2 in this order, when the operation signal from the electric opening / closing operation unit 119 is a closing signal, or when the operation signal from the emergency closing operation unit 132 is an activation signal In some cases, an operation signal may be input to the automatic closing device 241 for doors. Note that these functions may be implemented separately in separate control panels.

  As in the first embodiment, the interlock repeater 130 has a built-in standby power supply (battery) used in the event of a power failure, and the standby power supply is charged in a standby state. Do. Thus, the interlock repeater 130 is an opening / closing control means for opening / closing the door body 2 and the shutter curtain 101 in an interlocking manner.

  The basic operation of the interlock repeater 130 that controls the opening / closing operation of the shutter curtain 101 in normal operation is as follows. First, an operation signal (open signal, close signal, stop signal) from the electric opening / closing operation unit 119 is sent to the shutter switch control panel 113 for shutter. Relay. When an obstacle is detected during the electric closing operation (electrical descent), the shutter switch 101 is instructed to control the shutter curtain 101 to be reversed (opening control) (to the shutter switch 110). Input stop instruction signal and release instruction signal). During the opening / closing operation of the shutter curtain 101, the operation notification unit 118 is activated.

  As described above, the setting position of the upper limit switch of the upper / lower limit switch 122 is the fully open position of the shutter curtain 101. On the other hand, the setting position of the lower limit switch is a position slightly below the floor 7, which is an overrun caused by a failure of the seat plate switch 115 of the shutter curtain 101 during the closing operation (the winding of the shutter curtain 101). For detecting over-feeding from the shaft 106. That is, the lower limit switch is a seat plate switch failure diagnosis means for performing a failure diagnosis of the seat plate switch 115.

  The setting position of the extension limit switch 131 is a height position slightly above the floor 7 (for example, about 20 mm). That is, the extension limit switch 131 is activated (ON) when the shutter curtain 101 during the closing operation reaches a height position slightly above the floor 7 (closed movement).

  As described above, the automatic closing device for shutter 134 having the same shape, structure and function as the automatic closing device for door body 241 includes a door body opening / closing device by the operation of the automatic closing device for door body 241 in an emergency. When the door 212 that has started the closing operation after the brake 212 of 210 is released reaches the fully closed position (the door fully closed detection switch 82 is activated (ON)), an operation signal is input from the interlock repeater 130. The As a result, the brake 112 of the shutter opening / closing device 110 in the return state is released, and the shutter curtain 101 is closed (self-weight drop).

  As described above, the emergency closing operation unit 132 disposed in the vicinity of the electric opening / closing operation unit 119 includes the [actuation] switch 132A and the [return] switch 132B, which are push button switches, which are normally used. Sometimes it is covered with an acrylic cover to prevent manipulation.

  In the event of an emergency, the disaster prevention signal BS is not input to the interlocking repeater 130 from the sensor 18 or the disaster prevention center operation panel 19 for some reason, and is used when the automatic closing device 241 for the door body does not operate. When the [actuation] switch 132A of the emergency closing operation unit 132 is operated by a person such as an administrator, an operating signal (DC24V) that is equivalent to the disaster prevention signal BS is transmitted from the emergency closing operation unit 132 to the interlocking relay 130. To be input. For this reason, the [actuation] switch 132A of the emergency closing operation part 132 is an emergency that manually activates the door body automatic closing device 241 for releasing the brake 212 of the door body opening / closing device 210 in an emergency. It is a closing operation means. On the other hand, the [Return] switch 132B is used to return (return) the door body automatic closing device 241 that has released the brake 212 of the door body opening / closing device 210 to the original state.

  In normal times, when the [close] switch 119C of the electric opening / closing operation unit 119 is operated (pressed), a close signal (close operation instruction signal) is input from the [close] switch 119C to the interlock repeater 130. 130 inputs a close signal to the shutter switch control panel 113. The release power is supplied to the solenoid 145 of the shutter switch 110 from the shutter switch control panel 113 to which the closing signal is input, and the brake 112 is turned off (release state) when the solenoid 145 is energized. . After that, when driving power is supplied from the shutter switch control panel 113 to the motor 111 of the shutter switch 110, the drive shaft 140 of the motor 111 rotates forward, and the rotation of the drive shaft 140 of the motor 111 rotates. The force is transmitted to the winding shaft 106 through the driving force transmitting means 107. Thereby, the closing operation of the shutter curtain 101 by being fed out from the winding shaft 106 is started.

  Next, in the event of an emergency such as a fire, the operation of the shutter automatic closing device 134 according to the present embodiment for releasing the brake 112 of the shutter switch 110 that holds the shutter curtain 101 fully open will be described. To do.

  As shown in FIG. 19, when a disaster prevention signal BS (DC 24V) is input from the sensor 18 or the disaster prevention center operation panel 19 to the interlock repeater 130 in an emergency such as the occurrence of a fire, the interlock repeater 130 is used for the door body. An operation signal (DC 24 V) is input to the automatic closing device 241, and the door body 2 starts closing operation with the spring force of the torsion coil spring 16. When the door body 2 reaches the fully closed position and the door body fully closed detection switch 82 is activated (ON), a door body fully closed signal is input from the door body fully closed detection switch 82 to the interlocking relay 130. Thereafter, an actuation signal (DC 24 V) as a control signal is input from the interlock repeater 130 to a brake control circuit (not shown) of the shutter automatic closing device 134. The first slide member 150 of the shutter automatic closing device 134 is slid by the input of the operation signal, and the operation member 152 provided at the front end of the first slide member is the operated member 148 shown in FIG. In order to press the first part 147A of the lever member 147 of the shutter switch 110 in the direction C of FIG. 6 through the first part 147A, the first part 147A supports the second bent part 147D of the lever member 147 as described above. As shown in FIG. As a result, the brake shaft 142 and the brake drum 143 of the brake 112 of the shutter switch 110 are slid in the C ′ direction, which is the same direction as the C direction. 112 becomes off (release state).

  For this reason, the shutter curtain 101 that has been fully opened by the shutter opening and closing device 110 brake 112 causes the take-up shaft 106 to rotate forward due to its own weight such as the seat plate 101B below the take-up shaft 106. However, the closing operation (closing movement) is performed downward, and the above-described drive shaft 140 of the shutter switch 110 is also freely rotated through the driving force transmission means 107 (see FIG. 17), so that the shutter curtain 101 has the shutter upper and lower limits. The weight is lowered until the lower limit switch of the limit switches 122 is activated (ON).

  Thereafter, the second slide member 155 returns to the original position shown in FIG. 7, but the first slide member 150 is engaged with the roller 166 of the bending lever member 165 as described above, so that FIG. The brake 112 of the shutter switch 110 is kept off (released). That is, when the shutter curtain 101 is lowered by its own weight, the operating member 152 provided at the front end of the first slide member 150 is moved by the lever member of the shutter switch 110 via the operated member 148 shown in FIG. The state in which the first portion 147A of 147 is pressed in the direction C of FIG. 6 is continued.

  When the shutter curtain 101 falls under its own weight (closing operation), an obstacle exists in the closing operation direction of the shutter curtain 101, and the seat plate switch 115 provided on the seat plate 101B of the shutter curtain 101 hits this obstacle. When it is activated (ON) by contact, an obstacle detection signal from the seat plate switch 115 is input to the interlock repeater 130. As a result, an operation signal for operating (exciting) the solenoid 170 is input from the interlock repeater 130 to the DC solenoid 170 of the shutter automatic closing device 134. Thereby, the first slide member 150 slides to the original position by the spring force accumulated in the spring 164.

  As a result, the actuating member 152 provided at the front end of the first slide member 150 shows the first portion 147A of the lever member 147 of the shutter switch 110 via the actuated member 148 shown in FIG. The state of pressing in the C direction of 6 is released. As a result, the brake 112 that has been turned off (released) until then is turned on (returned), so that the free rotation of the drive shaft 140 of the shutter switch 110 is prevented, and the drive force transmission means 107 is used. Free rotation of the winding shaft 106 connected to the drive shaft 140 is also prevented. As a result, the drop of the weight of the shutter curtain 101 in contact with the obstacle stops.

  When the obstacle is removed from the stopped shutter curtain 10, the input of the obstacle detection signal from the seat plate switch 115 to the interlock repeater 130 is stopped. Thereafter, after the set time by the timer elapses, the operation for reactivating the shutter automatic closing device 134 from the interlock repeater 130 to the shutter automatic closing device 134 (for releasing the brake 112 again). A signal (DC24V) is input.

  Note that the floor control, which is the first specification, is used for the operation control specification of the shutter curtain 101 when the shutter curtain 101 having the seat plate switch 115 during the closing operation reaches the fully closed position (floor 7), that is, the lower limit stop operation specification. There are a surface stop specification and a floor surface push-in specification which is the second specification. In short, the difference in the lower limit stop operation specification is whether or not the floor 7 is handled as an obstacle when performing the closing operation control of the shutter curtain 101. This operation specification (operation mode) can be set by operating a DIP switch provided in the interlock repeater 130.

  The closing operation control of the shutter curtain 101 based on the difference in the lower limit stop operation specification will be described later. For example, when the lower limit stop operation specification is the first specification (floor surface stop specification), the shutter curtain 101 that is falling under its own weight. When the seat plate switch 115 of the shutter curtain 101 is activated (ON) by reaching the floor 7 in the fully closed position, the processing when the floor 7 is detected as an obstacle (the seat plate switch 115) is described above. The obstacle detection signal is input to the interlock repeater 130 and the return signal is input from the interlock repeater 130 to the shutter automatic closing device 134).

  Next, the flow of the closing operation control of the door body 2 and the shutter curtain 101 executed by the interlock repeater 130 in the normal state will be described with reference to the flowcharts of FIGS.

  As shown in FIG. 20, when the [close] switch 119C of the electric opening / closing operation unit 119 in the operation standby state (step S301-NO) is operated (ON) by the administrator, that is, the electric opening / closing operation. When the closing signal (closing instruction signal) for closing the door 2 is input from the unit 119 to the interlocking relay 130 (step S301-YES), the door 2 and the shutter curtain 101 by the interlocking relay 130 are displayed. The closing operation control is started (step S302).

In step S306, when the door obstacle detection device 133 is not operating (step S306-NO), input of an operation signal to the door automatic closing device 241 is started (step S307). As a result, the brake 212 of the door opening and closing machine 210 that has been turned on (returned) is released (step S308). As a result, the rotation axis of the door body 2 that has been prevented from rotating by the brake 212 of the door opening / closing device 210 can be freely rotated. That is, the door body 2 can be opened and closed.

  On the other hand, if the door obstacle detection device 133 is operating in step S306 (YES in step S306), the shutter opening / closing control panel 113 is instructed to stop the shutter curtain 101 closing operation control. Then (step S312 shown in FIG. 21), the closing operation control of the door body 2 and the shutter curtain 101 by the interlocking repeater 130 ends.

  After the step S308, the door body closing monitoring timer for determining whether or not the door body 2 is normally closed within a predetermined time is started (step S309). After step S309, the door body 2 is closed by the spring force of the torsion coil spring 16 (step S310).

  After this step S310, similarly to the above-described step S306, an operation determination process for the door obstacle detection device 133 is performed (step S311).

Further, a fully-closed detection signal from the door-body fully-closed detection switch 82 is input to the door-body automatic closing device 241 and the door-body automatic closing device 241 returns to its original state (step S319). Thereby, the brake 212 of the door opening and closing machine 210 is returned (ON) (step S320).

  After step S320, an instruction to start closing operation control of the shutter curtain 101 is executed to the shutter switch control panel 113 (step S321).

Thereby, the closing operation (self-weight drop) of the shutter curtain 101 is started (step S423).

  After this step S423, a determination process of the operation (ON) of the seat plate switch 115, that is, a determination process of the input of a shutter obstacle detection signal from the seat plate switch 115 is performed (step S424).

  In step S424, when the seat plate switch 115 is operated (ON) (YES in step S424), the determination process of the lower limit stop operation specification set by the operation of the dip switch, that is, the lower limit stop operation specification is performed. A determination process is performed as to whether the floor specification is the floor specification, which is the first specification (step S425).

  When the seat plate switch 115 is activated (ON), an obstacle detection signal is input from the seat plate switch 115 to the shutter automatic closing device 134, whereby the shutter switch 110 of the shutter 110 that has been released has been released. Since the brake 112 is in the return state, the weight drop of the shutter curtain 101 is stopped.

  In step S425, when the lower limit stop operation specification is not the floor surface push-in specification, in other words, when it is the floor surface stop specification (step S425-NO), the operation control process (failure of the shutter curtain 101 at the time of obstacle detection). The shutter curtain 101 is stopped until the object is removed and the seat plate switch 115 is turned OFF. When the obstacle is removed and the seat plate switch 115 is turned OFF, after a predetermined time (for example, 10 seconds). The shutter automatic closing device 134 is actuated again, and the shutter curtain 101 is lowered again (step S426). After step S426, the process returns to the determination process of step S424.

  In step S425, when the lower limit stop operation specification is the floor push-in specification (YES in step S425), a determination process for a power failure (impossible to supply power from the commercial power source 120) is performed (step S427).

  In this step S427, when there is a power failure (step S427-YES), the process of step S426 is executed.

  On the other hand, in step S427, when there is no power failure (NO in step S427), the operation control process of the shutter curtain 101 at the time of obstacle detection (the stopped shutter curtain 101 is reversed and raised for a predetermined time (for example, 2 seconds). Thereafter, the shutter curtain 101 is stopped until the obstacle is removed and the seat plate switch 115 is turned off. When the obstacle is removed and the seat plate switch 115 is turned off, a predetermined time (for example, 10 seconds) is reached. (After), the shutter automatic closing device 134 is actuated again to lower the shutter curtain 101 again (step S428). In this step S428, “inverse increase” is due to the driving (reverse driving) of the motor 111 of the shutter switch 110 based on the instruction from the interlocking relay 130 to the shutter switch control panel 113. At this time, The release of the brake 112 of the shutter switch 110 is due to energization (supply of release power) to the solenoid 145 of the shutter switch 110. After step S428, the process returns to the determination process of step S424.

  In step S424, when the seat plate switch 115 is not activated (ON) (step S424-NO), the operation limit (ON) determination process of the extension limit switch 131, that is, the extension lower limit from the extension limit switch 131 is determined. A signal input determination process is performed (step S429).

  In step S429, when the extension limit switch 131 is not activated (ON) (step S429-NO), the process returns to the determination process of step S424.

  On the other hand, if the extension limit switch 131 is activated (ON) in step S429 (step S429-YES), a closing confirmation signal is input to the disaster prevention panel or the like (step S427). After this step S427, it is determined whether or not the lower limit stop operation specification is the floor surface push-in specification that is the first specification (step S428).

  In this step S428, when the lower limit stop operation specification is the floor push-in specification (step S428-YES), the count of the seat plate switch operation invalid timer for counting the time for invalidating the operation of the seat plate switch 115 is counted. This is started (step S429), and thereby the operation of the seat plate switch 115 is invalidated, that is, the input of the obstacle detection signal from the seat plate switch 115 is invalidated (step S430).

  After step S430, a determination process is performed to determine whether the set time of the seat plate switch operation invalid timer has elapsed (step S431).

  In step S431, when the set time of the seat plate switch operation invalid timer has not elapsed (step S431-NO), the determination process of step S431 is repeated.

  On the other hand, if the set time of the seat plate switch operation invalid timer has elapsed in step S431 (step S431-YES), an obstacle detection signal is input to the shutter automatic closing device 134 (step S432). Thereby, the shutter automatic closing device 134 returns the brake 112 of the shutter opening / closing device 110 that has been released (step S433). As a result, the closing operation by the dead weight of the shutter curtain 101 is stopped (step S434).

  In step S428, when the lower limit stop operation specification is not the floor surface push-in specification (step S428-NO), a determination process of the operation (ON) of the seat plate switch 115 is performed (step S435).

  In this step S435, when the seat plate switch 115 is not operated (ON) (step S435-NO), this step S435 is repeated.

  On the other hand, in step S435, when the seat plate switch 115 is activated (ON), that is, when the seat plate switch 115 is activated by contacting the floor 7 (step S435-YES), the steps after step S432 are performed. The process is executed, whereby the closing operation by the dead weight of the shutter curtain 101 is stopped.
