Description

  The present invention relates to an opening / closing body control system for automatically closing an opening / closing body such as a shutter, and in particular, when an opening / closing body such as a fire prevention shutter is automatically closed in a fire, the opening / closing body can be arbitrarily urgently stopped in addition to detecting an obstacle. The present invention relates to an openable / closable body control system.

  In general, in passages and hall spaces inside buildings such as buildings with large floor areas, sheet or slat fire shutters that automatically close as soon as a fire occurs to prevent the spread of fire and the spread of smoke in the event of a fire. A fire-resistant opening / closing body that operates to form a space three-dimensionally enclosed with pillars, walls, floors, or the like, that is, a fire-proof section, is provided using a fire-resistant opening / closing body device such as a curtain device.

  FIG. 1 is a diagram showing a schematic configuration of a conventional fire shutter curtain device that forms such a fire protection section. A fire-resistant opening / closing device such as the fire-shutter curtain device 10 is connected to the switch 1 in response to the output of a disaster prevention signal BS (for example, a 24V DC signal) from a disaster prevention panel that senses smoke and heat generated in the event of a fire. It has a self-closing device 4 for releasing the applied brake 2. The automatic closing device 4 is operated by power from a commercial power source or a standby power source (battery power source) supplied via the repeater 3. Even if there is no supply of commercial power to the fire-proof shutter curtain device 10 in the event of a fire, the brake 2 can be released based on the input disaster-prevention signal BS, and the fire-proof structure is in a wound state. The shutter curtain 5 can be lowered by its own weight to automatically close the opening. In an emergency, the shutter curtain 5 can be lowered by its own weight by operating the emergency shutter closing button 8.

The fire shutter curtain device 10 is provided with an obstacle sensing device that detects contact with an obstacle during opening and closing. As shown in the figure, the obstacle sensing device includes a transmitter 6 provided on a seat plate at the lower end of the shutter curtain 5 and a receiver 7 provided in a storage box of the shutter curtain 5. The transmitter 6 wirelessly transmits a sensing signal to the receiver 7 when a seat plate switch (microswitch) is activated by an obstacle contact with the seat plate. At this time, the automatic closing device 4 controls to stop the closing operation of the shutter curtain 5 in accordance with the input of the sensing signal. Accordingly, when the seat curtain comes into contact with an obstacle when the shutter curtain 5 is moving down due to the occurrence of a fire, the lowering of the weight of the shutter curtain 5 is stopped. For example, Patent Document 1 discloses a device relating to such a fire-proof shutter curtain device.
Japanese Utility Model Publication No. 3-58599

The conventional fire shutter curtain device is configured to stop the descent operation if the obstacle sensing device intentionally senses the obstacle even if there is no effective stop button etc. during the descent of the dead weight. Despite being used, the user may not be able to recognize that it can be stopped by obstacle detection, and if the user wants to stop the descent operation of the shutter curtain urgently for some reason, he cannot take the act of stopping the shutter. There was a thing.
The present invention has been made in view of the above points, and provides an opening / closing body control system capable of urgently stopping the lowering operation of an opening / closing body such as a shutter curtain even when there is no stop button or the like. Objective.

The first feature of the opening / closing body control system of the present invention is that the opening / closing body means provided in the opening, the closing instruction means for outputting a closing signal in response to an artificial operation, and the opening signal in response to the input of the closing signal Control means for closing the opening / closing body means, and closing operation stopping means for stopping the closing operation of the opening / closing body means for a predetermined time when the closing signal is output during the closing operation of the opening / closing body means. Be prepared.
The opening / closing body means is composed of an opening / closing member such as a shutter curtain that opens and closes an entrance / exit, a window, or an opening of an internal passage or space in a structure such as a building, a house, a factory, or a warehouse. It is fed out to partition the opening in the event of a fire or closing. When the opening / closing body means is, for example, a fire shutter curtain, it is stored in the upper part of an opening of a building or the like, passes through a lintel or the like, and the fire shutter curtain is lowered to close the opening. In addition to this, the opening / closing body means may be housed in the side portion of the opening and opened / closed by a horizontal pulling method, or may be housed in the lower part of the opening and opened / closed by an ascending method. The closing instruction means is an operation button such as an emergency shutter closing button, and outputs a closing signal when operated artificially. The control means inputs and closes the opening by moving the opening / closing body means such as a shutter curtain by inputting the closing signal. Conventionally, when the opening / closing body means starts to close by operation of an emergency shutter closing button, etc., when the opening / closing body means is provided with an obstacle sensing means such as a seat plate switch, or when a stop button is provided, When the obstacle is detected or the stop button is operated, the closing operation of the opening / closing body means can be stopped. However, if a stop button is not provided, for example, in the case of a fire shutter curtain, etc., the main purpose is fire and smoke prevention, so the stop button may not be provided at a position that can be operated by an unspecified person. If, for some reason, it is desired to stop the closing operation of the opening / closing member means, the obstacle detecting means such as a seat plate switch provided at the closing end of the opening / closing member means can be operated. . In the present invention, when the closing instruction means is operated during the closing operation and a closing signal is output, it is assumed that the signal is a signal for stopping the closing operation, and while the signal is being output, the opening / closing body means The closing operation of was stopped. That is, the closing instruction means is also used as a stop operation instruction means for instructing the stop of the closing operation. As a result, even when a stop button or the like is not provided, the lowering operation of the opening / closing body means such as the shutter curtain can be urgently stopped without being confused by the means.

The second feature of the opening / closing body control system of the present invention is that the opening / closing body means provided in the opening, the closing instruction means for outputting a closing signal in response to an artificial operation, and the closing signal or the closing signal An automatic closing means for closing the opening / closing body means in response to an input of a different signal, and a closing operation of the opening / closing body means for a predetermined time when the closing signal is output during the closing operation of the opening / closing body means And a closing operation stopping means for stopping the operation.
This is because, for example, the opening / closing body means is used for forming a fire prevention section, and it is used for inputting a signal different from a normal closing signal such as a disaster prevention signal or an emergency closing signal generated in the event of a fire or a normal closing signal In response to this, automatic closing means for automatically starting the closing operation is provided. In the case of such an open / close body means for fire prevention and smoke prevention, a stop button may not be provided, so that a closing instruction means such as a shutter close button is also used as a stop button. Thereby, for example, even when the stop button or the like is not provided as in the case of the opening / closing body means for forming the fire prevention section, the lowering operation of the opening / closing body means such as the fire shutter curtain can be urgently stopped.

According to a third feature of the opening / closing body control system of the present invention, in the opening / closing body control system described in the second feature, the closing operation stop means is connected to the automatic closing means in response to an input of the closing signal. The purpose is to control the supply of power.
Usually, the automatic closing means releases the brake by receiving power from a power source or a standby power source (battery power source), and lowers the fire shutter curtain or the like by its own weight. In addition, there is also a device that lowers its own weight by cutting off the power supply. Therefore, in the present invention, by controlling the supply of electric power to the automatic closing means according to the input of the closing signal, the braking operation is operated to stop the lowering operation of the opening / closing body means.

The fourth feature of the opening / closing body control system of the present invention is that the opening / closing body means provided in the opening, the closing instruction means for outputting a closing signal in response to an artificial operation, and the operating path of the opening / closing body means Obstacle sensing means for outputting an obstacle sensing signal when an obstacle is sensed, control means for closing the opening / closing body means according to the input of the closing signal, and according to the input of the obstacle sensing signal In an opening / closing body control system comprising a closing operation stopping means for stopping the opening / closing body means during closing operation, the closing operation stopping means is provided when the closing signal is output during the closing operation of the opening / closing body means. In the same manner as the operation of stopping the opening / closing member means during the closing operation according to the input of the obstacle sensing signal, the opening / closing member means during the closing operation is stopped according to the input of the closing signal. .
This relates to an open / close body control system in the case where the open / close body means includes obstacle sensing means. The obstacle sensing means detects the presence of an obstacle on the operating path during the operation of the opening / closing body means, and is constituted by, for example, a seat plate switch provided at the front end of the moving part of the opening / closing body means. The When the obstacle sensing means detects the obstacle, the control means stops the closing operation of the opening / closing body means accordingly. Therefore, in the present invention, when the closing instruction means is artificially operated during the closing operation of the opening / closing body means using the function that the obstacle sensing means and the control means stop the opening / closing body means, the closing signal Is processed in the same manner as the obstacle detection signal, and the closing operation of the opening / closing member means is stopped only while the closing signal is output.

The fifth feature of the opening / closing body control system of the present invention is that the opening / closing body means provided in the opening, the closing instruction means for outputting a closing signal in response to an artificial operation, and the operating path of the opening / closing body means Obstacle detection means for outputting an obstacle detection signal when an obstacle is sensed, automatic closing means for closing the opening / closing body means in response to an input of the closing signal or a signal different from the closing signal, and In the opening / closing body control system provided with a closing operation stopping means for stopping the opening / closing body means in a closing operation in response to an input of an obstacle detection signal, the closing operation stopping means is configured to stop the opening / closing body means during the closing operation of the opening / closing body means. When the closing signal is output, the opening / closing operation during the closing operation according to the input of the closing signal is the same as the operation of stopping the opening / closing body means during the closing operation according to the input of the obstacle sensing signal. Stop the body means It lies in the fact.
Similarly to the second feature, the opening / closing body means is for, for example, forming a fire prevention section, and is a normal closing signal such as a disaster prevention signal or an emergency closing signal generated at the time of a fire or the like. The present invention relates to an opening / closing body control system provided with an automatic closing means for automatically starting a closing operation in response to an input of a different signal or a normal closing signal, and further provided with an obstacle sensing means. In the case of such opening and closing means for fire prevention and smoke prevention, since there is no stop button, when a closing signal is output, the closing instruction means such as a shutter closing button is also used as a stop button. The closing operation stopping means is caused to perform the same processing as when the obstacle detection signal is input, and the closing operation of the opening / closing body means is stopped only while the closing signal is output. Thereby, even when the stop button or the like is not provided as in the case of the opening / closing body means for forming the fire prevention section, the lowering operation of the opening / closing body means such as the fire shutter curtain can be stopped urgently.

According to a sixth aspect of the switchgear control system of the present invention, in the switchgear control system described in the fifth feature, the automatic closing means is configured to respond to the obstacle detection signal or the input of the closure signal. The purpose is to control the power supply to the automatic closing means.
As in the third feature, the power supply to the automatic closing means is controlled in response to the input of the obstacle sensing signal or the closing signal, thereby operating the braking and lowering operation of the opening / closing body means. Is to stop.

According to a seventh feature of the opening / closing body control system of the present invention, in any one of the opening / closing body control systems described in the first feature to the sixth feature, the closing operation stop means is different from the closing instruction means. Holding means for self-holding the closing signal for a predetermined time, and controlling the supply of electric power to the automatic closing means when the closing signal is inputted during the self-holding of the closing signal by the holding means And a power supply control means for stopping the closing operation of the opening / closing body means.
This is because the power supply control means automatically closes when the closing operation stopping means self-holds the closing signal in a circuit and the closing instruction means is artificially operated during this self-holding and the closing signal is output again. The power supply to the means is controlled (stopped or started) to operate the braking to stop the lowering operation of the opening / closing body means.

An eighth feature of the opening / closing body control system of the present invention is that, in the opening / closing body control system described in the seventh feature, the power supply control means is operated in conjunction with an artificial operation of the closing instruction means. The closing operation of the opening / closing body means is stopped by controlling the supply of electric power to the closing means.
This is because the power supply control means controls the power supply in conjunction with the act of artificially operating the closing instruction means to stop the lowering operation of the opening and closing means by operating braking. Is.

According to a ninth feature of the switchgear control system of the present invention, in the switchgear control system described in the eighth feature, the power supply control means is in an electrically insulated state from the closure instruction means, The purpose is to control the supply of electric power to the automatic closing means via a contact that is operated simultaneously with direct or indirect contact according to the artificial operation.
Since the closing instruction means includes a movable part that is turned on and off by being manually operated, for example, a switching device, the power supply control means is electrically insulated from the closing instruction means. However, it is equipped with a contact that can be operated by moving directly and indirectly with this movable part, and the power supply can be stopped or started by turning this contact on and off. Then, the lowering operation of the opening / closing member means is stopped by operating the braking.

According to a tenth feature of the opening / closing body control system of the present invention, in the opening / closing body control system described in the eighth feature, the power supply control means is only operated while the closing instruction means is artificially operated. It is to control the supply of electric power to the automatic closing means via a relay contact configured to be switched on and off by a driving relay means configured to allow current to flow.
Since the closing instruction means is turned on / off by being manually operated, for example, like a switching device, the power supply control means has a current corresponding to the on / off state of the closing instruction means. Using the drive relay configured as described above, the power supply is stopped or started by the relay contact that is switched on and off by the current flowing through the drive relay, and braking is activated to open and close The descending operation of the body means is stopped.

  According to the opening / closing body control system of the present invention, there is an effect that the lowering operation of the opening / closing body such as a shutter curtain can be stopped urgently.

  Hereinafter, a fire shutter curtain device according to an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 2 is a diagram showing an outline of the opening / closing body control system according to the present invention. The opening / closing body device controlled by the opening / closing body control system is a fire shutter curtain device as shown in FIG. This fire-proof shutter curtain device is normally in an open state wound up basically, and this open state is mechanically held by the brake 2. When the fire breaks out, the opening / closing body control system releases the holding state of the brake 2 in accordance with the input of the disaster prevention signal BS or the operation of the emergency shutter closing button 8 and naturally lowers the shutter curtain by its own weight. Thus, the opening is closed to form a predetermined fire prevention compartment.

  The difference between the opening / closing body control system shown in FIG. 2 and the conventional one is that the seat switch is operated in the same manner as when an obstacle is detected in conjunction with the operation of the emergency shutter closing button 8. Is a point. That is, in this embodiment, the opening / closing body control system is configured such that both the repeater 3 and the automatic closing device 4 perform an operation corresponding to the operation of the emergency shutter closing button 8.

  The opening / closing body control system includes a repeater 3 and an automatic closing device 4. The repeater 3 controls power supply to the automatic closing device 4. The automatic closing device 4 operates an automatic closing circuit 41 in response to power supply from the power supply unit 21 to release the holding state of the brake 2 and causes the shutter curtain 5 to drop naturally by its own weight.

  The repeater 3 includes a power supply unit 30 to which external commercial AC power (AC100 [V] or AC200 [V]) is supplied via terminals P0 and P1. The power supply unit 30 incorporates a standby power supply such as a battery that serves as a power supply source of a separate system from the commercial AC power supply. Therefore, the power supply unit 30 can operate the automatic closing device 4 with a standby power supply even if it cannot receive supply of commercial AC power in an emergency.

  Between the power supply unit 30 and the automatic closing device 4, a recovery switch (SW4) 31, an external recovery switch 32, an external start switch 8A, a start switch (SW3) 33, and a first relay A contact (RY1) 34, a second relay contact (RY2) 35, diodes 36 and 37, and a second drive relay 38 are provided. On the other hand, the 1st drive relay 39 which inputs the sensor signal of DC24 [V], such as disaster prevention signal BS, is provided with the diode.

  The recovery switch (SW4) 31 and the external recovery switch 32 forcibly stop the supply of power to the automatic closing device 4. The external start switch 8A is switched on in conjunction with the emergency shutter closing button 8. The emergency shutter closing button 8 is a red emergency operation button that is covered with a resin panel and is operated by pushing the resin panel in an emergency. The start switch 33 is a switch for operating the automatic closing device 4 at the time of maintenance and inspection other than the emergency operation button. The first relay contact 34 is a relay that is switched on by a first drive relay 39 that is driven by the input of a sensor signal of DC 24 [V]. The second relay contact 35 is switched on when any of the external start switch 8A, the start switch (SW3) 33 or the first relay contact (RY1) 34 is turned on and a current flows to the second drive relay 38. It is a relay.

  As described above, when any of the external start switch 8A, the start switch (SW3) 33, or the first relay contact (RY1) 34 is switched on, the second relay contact 35 is turned on, and the state is maintained. Become so. This holding state can be canceled by turning off one of the recovery switch (SW4) 31 and the external recovery switch 32. The diode 36 prevents inflow of current from the external start switch 8A, the start switch 33, or the first relay contact 34.

  On the other hand, the automatic closing device 4 is configured to stop the supply of power to the automatic closing circuit 41 only when the seat plate switch 42 or the external activation switch 8B is in the switch-on state. That is, the third drive relay 43, the diode 44, the third relay contact 45, the contact of the seat plate switch 42 and the external start switch 8 </ b> B connected in series are provided in parallel to the automatic closing circuit 41. Note that the contact of the seat plate switch 42 and the external activation switch 8B are connected in parallel. The third relay contact 45 is a relay that is switched off by the third drive relay 43 that is driven when the seat plate switch 42 or the external activation switch 8B is switched on. Therefore, when one of the contacts of the seat plate switch 42 or the external activation switch 8B is turned on, the third relay contact is turned off by the third drive relay 43, and the power supply to the automatic closing circuit 41 is stopped. The descent of the shutter curtain stops. Here, the external activation switch 8B is switched on in conjunction with the emergency shutter closing button 8. That is, the emergency shutter closing button 8 is a push button composed of a 2a contact type external start switch 8A and an external start switch 8B that are linked to a pressing operation.

  Therefore, when the emergency shutter closing button 8 is pressed, the external activation switches 8A and 8B are turned on, a current flows through the second drive relay 38, and the second relay contact 35 is turned on, and this state is maintained. . If the emergency shutter closing button 8 is kept pressed, the external activation switch 8B is in an on state, so that the third relay contact 45 is switched off and no power is supplied to the automatic closing circuit 41. The shutter curtain 5 remains stored in the storage box.

  At this time, when the emergency shutter closing button 8 is released, the external activation switches 8A and 8B are turned off. Even when the external start switch 8A is turned off, the second relay contact 35 remains on, so that the automatic closing device 4 is supplied with electric power. On the other hand, when the external start switch 8B is turned off, the third relay contact 45 is turned on and power is supplied to the automatic closing circuit 41, so that the holding of the open state by the brake 2 is released and the shutter is released. Curtain 5 starts its own weight drop.

  When the emergency shutter closing button 8 is pressed again while the shutter curtain 5 is falling under its own weight, the external activation switches 8A and 8B are turned on again. However, since the second relay contact 35 is already in the ON state, this state is maintained as it is. On the other hand, when the emergency shutter closing button 8 is pressed, the external activation switch 8B is turned on, the third relay contact 45 is turned off, the power supply to the automatic closing circuit 41 is cut off, and the shutter curtain 5 The descent operation stops. This stop state is continued according to the pressing state (push-out state) of the emergency shutter closing button 8. Therefore, when the pressed state (push-out state) of the emergency shutter closing button 8 is released, the shutter curtain 5 starts to descend its own weight again.

  FIG. 3 is a diagram showing an outline according to another embodiment of the opening / closing body control system according to the present invention. In FIG. 3, since the same code | symbol is attached | subjected to the thing of the same structure as FIG. 2, the description is abbreviate | omitted. 3 differs from that of FIG. 2 in that a fourth relay contact 8C is provided instead of the external activation switch 8B, the emergency shutter closing button 8 is pressed, and the external activation switch 8A is turned on. In this case, a current flows through the fourth drive relay 3A, the fourth relay contact 8C is turned on, the third relay contact 45 is switched off, the power supply to the automatic closing circuit 41 is cut off, and the shutter curtain 5 This is the point that the descent operation of the ceased. The diode 3B prevents inflow of current from the start switch 33, the first relay contact 34, or the second relay contact 35.

  FIG. 4 is a flowchart showing an example of the operation of the opening / closing body control system. First, in step S41, the open / close body control system determines whether or not the sensor signal from the heat sensing device such as the smoke sensor or the heat sensor has been received, or the emergency shutter closing button 8 is pressed, and the external activation switch 8A is activated. It is determined whether or not it is on. If it is received or turned on (yes), the process proceeds to the next step S42, and if it is not received or not on (no), the signal is received. The determination process in step S41 is repeated until it is turned on or turned on.

  In step S42, since the opening / closing body control system receives the sensor signal or the external activation switch 8A is turned on, the opening / closing body control system releases the brake. Thereby, in step S43, the shutter curtain 5 starts to descend by its own weight by releasing the brake.

  In step S44, it is determined whether or not any obstacle has contacted the seat plate at the lower end of the shutter curtain 5, and is detected by a micro switch built in the seat plate. The process proceeds to S47, and if not detected (no), the process proceeds to Step S45.

In step S45, it is determined whether or not the emergency shutter closing button 8 is pressed and the external activation switch 8A is in the on state. If it is in the on state (yes), the process proceeds to step S47, and if not (no), the process proceeds to step S46. Proceed to
That is, when the obstacle detection signal is not output from the micro switch and when the emergency shutter closing button 8 is not pressed, the process proceeds to step S46 in order to continue the closing operation of the shutter curtain 5 as it is. In step S46, the lowering operation of the shutter curtain 5 is continued, and the process returns to step S44. Note that when the shutter curtain 5 descends and comes into contact with the floor or the like and becomes fully closed, it cannot be further closed, and in this case, the process is stopped. On the other hand, when an obstacle detection signal is output from the micro switch and it is determined yes in step S44, or when the emergency shutter closing button 8 is pressed and the external activation switch 8A is turned on, Proceed to step S47.

  The determination of “yes” in step S44 and step S45 means that the seat plate has come into contact with some obstacle during the lowering operation of the shutter curtain 5, or the emergency shutter closing button 8 has been pressed. Therefore, in step S47, the descent of the shutter curtain 5 is stopped. The stop here is to apply braking, and the stop state is maintained until the brake is released in step S42.

  In step S48, the determination in step S48 is repeated until the obstacle detection signal is not continuously detected from the micro switch built in the seat plate or the pressing state of the emergency shutter closing button 8 is released. When it is no longer sensed or when the pressed state is released, the process returns to step S42, the brake is released, and the weight drop is resumed. In this embodiment, as long as the obstacle detection signal is continuously sensed, or as long as the emergency shutter closing button 8 is in the pressed state, a flow is shown in which this step S48 cannot be exited. .

FIG. 5 is a diagram showing a modification of the automatic closing circuit of the opening / closing body control system according to the present invention, and is a diagram showing only the automatic closing circuit and its peripheral circuit configuration. The automatic closing circuit 41 shown in FIG. 2 and FIG. 3 receives the supply of electric power from the power supply unit 21, thereby releasing the holding state of the brake 2 and lowering the shutter curtain 5 by its own weight. When the supply is cut off, the brake 2 performs an operation of stopping the weight drop of the shutter curtain 5. Therefore, as shown in FIG. 5A, when the automatic closing circuit 411 is disconnected from the power supply from the power source 21, the release state of the brake 2 is released and the shutter curtain 5 is lowered by its own weight. When the reverse operation of stopping the lowering of the weight of the shutter curtain 5 by the brake 2 is performed by receiving the power supply, as shown in FIG. 5A, as the third relay contact 451, A contact switch may be used. In addition, as shown in FIG. 5B, when the automatic closing circuit 412 adopts a method of switching the power supply between the operating circuit and the return circuit, in order to stop the weight drop of the shutter curtain 5, As shown in FIG. 5B, the power supply may be switched using a c-contact switch as the third relay contact 452.

  In the above-described embodiment, when the obstacle detection signal is no longer sensed or when the pressed state is released, the process returns to step S42. Even in the sensing state or the pressed state, the process may return to step S42 when the predetermined time elapses, and the descent may be resumed. In some cases, the descent may be performed for a predetermined distance or may be performed for a predetermined time. Good.

  In the above-described embodiment, the fire shutter shutter device that is extended and closed while the shutter curtain that is the opening and closing member is closed is described as an example, but the opening and closing member is extended by the horizontal pulling method or the raising method. It can be applied in the same way even if it is fed out by the horizontal direction or is fed out by the horizontal method. The opening / closing body may be, for example, a shutter device, a blind device, a roll screen device, a banner device, or the like. When the opening / closing body device is a shutter device, the opening / closing member, which is an opening / closing body means, is a shutter curtain, and its structure is composed of a slat curtain made of a large number of strip-shaped slat materials and a large number of pipe materials connected by link materials. Pipe curtains made from one piece, panel curtains made from one or more connected panel materials, net curtains made from net materials, sheet curtains made from synthetic resin or cloth fiber sheet materials, or composite members thereof This is due to the composite curtain. The material of the opening / closing member that is the opening / closing member means may be any material as long as it is suitable for the purpose of use. Specifically, it can be made of metal, wood, plastic, cloth, or a composite of these. In the case of an opening / closing body device installed for the purpose of fire prevention, the material of at least the opening / closing member which is the opening / closing body means preferably has fire resistance.

  In the above-described embodiment, an example in which an obstacle is detected by abutting against the obstacle, such as a seat plate switch, has been described as an example, but other obstacles can be detected by a tape switch or non-contact. It may be a thing. For example, as an object that detects an obstacle without contact, an infrared light emitting element and a light receiving element are provided on both sides of the opening / closing member, and the obstacle is detected when the infrared light is blocked. There is. The obstacle detection means detects an obstacle present in the opening including the periphery of the opening.

  Further, in the above-described embodiment, when the obstacle detection signal is transmitted, the wireless method is described as an example, but other than this, a wired method or infrared light is used, or a frequency signal (sound wave, ultrasonic wave, radio wave, etc.) is used. ) May be used. When radio waves or the like are used, the obstruction due to the rotating guide rail is extremely small, so that the obstacle detecting means can be arranged at a relatively free position. Therefore, in the case of a frequency signal, it is preferable that the frequency signal is arranged so as not to be obstructed by the guide rail in the case of an ultrashort wave having a certain degree of straightness.

  In the above-described embodiment, the case where the weight drop is stopped only while the emergency shutter closing button 8 is in the pressed state is described. However, a timer device is added to an appropriate portion of the circuit of FIG. After the shutter closing button 8 is pressed or released, the weight drop may be resumed after a predetermined time counted by the timer device. Further, in the above-described embodiment, the case where the weight drop is temporarily stopped has been described. However, the opening operation may be reversed after the stop, and the closing operation is continued without stopping or reversing, but the operation speed is increased. It is also possible to decelerate.
