Means 40, and when the opening / closing body 10 is stopped at an opening / closing position, the lower end side of the opening / closing body 10 is subjected to a contact operation or a proximity operation (contact operation according to the illustrated example). Do.

  The opening / closing body 10 is arranged in the opening / closing body width direction via a connecting member 12 at the closing direction end of the opening / closing body main body 11 so as to move in the opening / closing direction relative to the opening / closing body main body 11. And a movable seat plate 13 connected over the entire surface.

According to this configuration, when the swing piece 14 swings as the movable seat plate 13 is lifted, the swing piece 14 is moved through the opening 12a2 to the movable seat of the object sensing unit 42 on the capturing side. It is sensed by the plate sensing sensor 42f.

The movable seat plate 13 is a long member continuous in the lateral width direction of the opening / closing body 10 and is connected to the lower end of the connection member 12 so as to freely move by a predetermined amount in the opening / closing body opening / closing direction. (See FIG. 2).
The movable seat plate 13 functions as contact sensing means for sensing contact of the object X closer to the closing direction than the opening / closing body 10 during the closing operation of the opening / closing body 10, and stops at the position where the opening / closing body 10 is being opened / closed. In the inside, in cooperation with the swing piece 14, the movable seat plate sensor 42 f, and the like, it functions as an operated part A that generates an operation signal by a contact operation from the closing direction side of the opening / closing body 10.

  In the figure, reference numeral 15 denotes a retaining member fixed to an end of the opening / closing body 11 in the width direction, and this retaining member 15 is engaged with an object sensing unit guide member 21 (see FIG. 3) described later. Thus, the opening / closing body 10 is prevented from coming off the guide rail 20 in the lateral direction of the opening / closing body.

  The guide rail 20 is a member configured to surround an end portion of the opening / closing body 10 in the horizontal width direction, and a contact target portion p (for example, a floor surface, the ground, a frame member, etc.) seated by the opening / closing body 10. ) And the winding device 30.

An object sensing unit guide member 21 is fixed inside the guide rail 20 (see FIG. 3). The object sensing unit guide member 21 slides object sensing units 41 and 42, which will be described later, in the opening / closing body opening / closing direction. I support it.
This object sensing unit guide member 21 is formed with a guide portion 21a having a U-shaped cross section that engages with the object sensing unit 41 (or 42) in the opening / closing direction of the opening / closing body. The guide portion 21a guides the object sensing unit 41 (or 42) so as to be slidable in the opening / closing body opening / closing direction, and moves the object sensing unit 41 (or 42) in the opening / closing body lateral width direction and the opening / closing body thickness direction. Stop.

  In addition, the winding device 30 includes a winding shaft 32 that winds and unwinds the opening / closing body 10 in a storage case 31 in which an opening (lintel portion) for allowing the opening / closing body 10 to appear and retract on the lower side is formed.

The control unit 34 is not illustrated, and includes an operation switch, a remote control device, an opening / closing position detection means 35, and an object detection. The drive source 33 is rotated or stopped in the forward direction or the reverse direction in accordance with the signal from the means 40 and the operated part A.

The open / close position detecting means 35 is a well-known mechanism that combines a counter mechanism that mechanically counts the amount of rotation of the drive source 33 and a microswitch that operates when the count value of the counter mechanism exceeds a predetermined value. is there. The opening / closing position detecting means 35 outputs a fully open signal when the opening / closing body 10 is fully opened, and outputs a fully closed signal when the opening / closing body 10 is fully closed. The full open signal and the full close signal may be non-voltage contact signals, but may be voltage signals.
Other examples of the opening / closing position detecting means 35 include a mode in which the rotation amount of the drive source 33 and the take-up shaft 32 is detected by an encoder or the like, and the opening / closing body 10 at the fully open position or the fully closed position is attached to the guide rail 20. It is also possible to adopt a mode in which detection is performed by a provided proximity switch.

  Further, the object sensing means 40 is provided at one end side of the opening / closing body 10 in the lateral width direction and is provided at the discharge side object sensing unit 41 for emitting the object sensing medium b, and is provided at the other end side to capture the object sensing medium b. And an object sensing unit 42 on the capturing side (see FIG. 1).

  The discharge-side object sensing unit 41 protrudes from the closing direction end of the opening / closing body in the opening / closing body closing direction and retreats by contact with a contact target portion p (for example, a floor surface, the ground, a frame member, etc.). The slide body 41a provided in the above manner, the discharge portion 41b provided on the lower end side of the slide body 41a for discharging the object sensing medium b in the lateral width direction of the opening / closing body, and the upper side while protecting the electric wiring 41g of the discharge portion 41b An electrical wiring guide member 41c for guiding the electrical wiring guide member 41c, a connection member 41d for connecting the electrical wiring guide member 41c to the slide body 41a, and the object sensing unit 41 disposed on the opposite side of the connection member 41d in the opening / closing body thickness direction. And a weight 41e for correcting the weight balance in the thickness direction of the opening / closing body substantially evenly (see FIG. 2).

  The capture-side object detection unit 42 has an appearance in which the left and right sides of the discharge-side object detection unit 41 are roughly reversed. More specifically, the capture-side object detection unit 42 protrudes from the closing direction end of the opening / closing body in the opening / closing body closing direction. And a slide body 42a provided so as to be retracted by contact with a contact target portion p (for example, a floor surface, the ground, a frame member, etc.), and a discharge portion 41b provided on the lower end side of the slide body 42a. A capturing part 42b that captures the object sensing medium b to be released, and a movable seat plate sensor 42f (for example, a proximity sensor) that senses the swing of the swing piece 14 accompanying the relative upward sliding of the movable seat plate 13. Etc.), an electrical wiring guide member 42c for guiding upward while protecting the electrical wiring 42g of the capturing part 42b and the movable seat plate sensor 42f, and connecting the electrical wiring guide member 42c to the slide body 42a A connecting member 42d, and a weight 42e disposed on the opposite side of the connecting member 42d in the opening / closing body thickness direction to correct the weight balance of the object sensing unit 42 in the opening / closing body thickness direction substantially evenly. (See FIG. 2).

  The example shown in FIG. 2 shows an object sensing unit 42 on the capture side, and the object sensing unit 41 on the emission side is disposed symmetrically with respect to the object sensing unit 42 and is also a movable seat plate sensing sensor. 42f is omitted.

  The emitting unit 41b and the capturing unit 42b are configured to capture the object sensing medium b emitted from one of them, and for example, a photoelectric sensor that emits and captures infrared rays is used as the object sensing medium b.

  The object sensing units 41 and 42 having the above-described configuration engage the concave grooves 41a1 and 42a1 in the slide bodies 41a and 42a with the convex portions 12a1 and 12a1 of the connecting member 12, respectively. It is suspended so as to be relatively slidable in the vertical direction.

Next, a characteristic operation of the switchgear 1 having the above configuration will be described.
As shown in FIG. 1, when the object X is present closer to the closing direction than the opening / closing body 10 during the normal closing operation, the control unit 34 detects that the object sensing medium b emitted from the emission unit 41 b is the object X. Is detected, the control of the drive source 33 causes the closing operation of the opening / closing body 10 to be temporarily stopped, followed by a reversing operation (opening operation) for a predetermined time and then again.
In the unlikely event that the discharge part 41b and the capture part 42b do not detect due to failure, dirt on the discharge surface, etc., the movable seat plate 13 abuts against the object X and the opening / closing body 11 2, the swing piece 14 (see FIG. 2) swings and is detected by the movable seat plate sensor 42 f in the object detection unit 42, and a detection signal is received from the movable seat plate sensor 42 f. Is output. When the control unit 34 receives the detection signal from the movable seat plate sensor 42f, the control unit 34 controls the drive source 33 to temporarily stop the closing operation of the opening / closing body 10, and after performing the reversing operation (opening operation) for a predetermined time, the control unit 34 again. Stop.

  Note that the non-contact detection or the reversing operation after the contact detection is such that the movable seat plate 13 moves away from the object X to some extent, and the movable seat plate 13 returns to the lower limit side of the vertical movement range relative to the opening / closing body 11. The reversal operation amount is appropriately set so that the signal output by the plate detection sensor 42f is not performed.

As described above, when the opening / closing body 10 is stopped at the halfway opening / closing position (see FIG. 1), the control unit 34 performs the control shown in the flowchart of FIG.
More specifically, first, the control unit 34 determines whether or not the opening / closing body 10 is stopped (step 1). If it is stopped, the control unit 34 proceeds to the next step 2, and so on. If this is the case, it waits for the opening / closing body 10 to stop, or shifts to another step (not shown).
The determination as to whether or not the opening / closing body 10 is stopped may be based on a signal on the control circuit such as a contact signal of a relay that turns on and off the drive source 33.

  In step 2, it is determined whether or not the opening / closing body 10 is stopped at the fully open position based on the presence / absence of the fully open signal from the opening / closing position detecting means 35. If not, the process proceeds to the next step 3.

  In step 3, it is determined whether or not the opening / closing body 10 is stopped at the fully closed position based on the presence / absence of the fully closed signal from the opening / closing position detection means 35. Returns the process to step 1, otherwise proceeds to the next step 4.

In step 4, it is determined whether or not there is an operation signal for the movable seat 13 (operated part A). If there is an operation signal, the process proceeds to step 5; otherwise, the process returns to step 1.
That is, in a state where the opening / closing body 10 is stopped halfway, an operation article H (a human hand or the like) is hung on the movable seat plate 13 (see FIG. 1), and the movable seat plate 13 is lifted to face the opening / closing body main body 11. When it rises, the swing piece 14 rotates inside the lower end of the opening / closing body 10 (see FIG. 2), and the swing piece 14 is detected by the movable seat plate sensor 42f, and the detection signal is controlled. Input to the unit 34. And the control part 34 advances a process to the following step 5 according to the said sensing signal.

In step 5, a control command for causing the drive source 33 to perform a reverse operation for a predetermined time is output, and the opening / closing body 10 is opened by a predetermined amount.
More specifically, the control unit 34 drives and rotates the drive source 33 in the opening direction, operates a timer (not shown), and sets the count of the drive source 33 on the condition that the count by the timer exceeds a predetermined time. Stop driving rotation. The predetermined time is appropriately set so that the object X on the closing direction side of the opening / closing body 10 can be easily removed and the closing performance by the opening / closing body 10 is not significantly impaired.

  After step 5, the process by the control unit 34 is returned to step 1. Therefore, even after the opening operation of the predetermined amount of the opening / closing body 10 is stopped, the contact operation with respect to the movable seat 13 (operated part A) is performed again, and the control unit 34 receives an operation signal from the operated part A. Is received again, the opening operation of the predetermined amount of the opening / closing body 10 is resumed. Such re-operation can be repeated.

  Even in the flow shown in FIG. 4, when there is an operation by an operation switch (not shown) or a remote control device, or when there is another control command (not shown) or the like, the operation, the command, etc. Control (not shown) is performed.

Therefore, according to the opening / closing device 1 configured as described above, when the opening / closing body 10 is stopped at the opening / closing position, the operation article H (for example, a hand) is brought into contact with the movable seat plate 13 (operated portion A). By operating upward, the opening / closing body 10 can be opened by a predetermined amount, and thereafter, if the contact operation is repeated, the opening / closing body 10 can be repeatedly opened by a predetermined amount.
For this reason, for example, when the object X exists on the opening direction side of the opening / closing body 10 and the opening / closing body 10 is stopped by the detection of the object detecting means 40, the opening / closing body 10 is lifted by placing a hand or the like on the lower end. By the natural operation, the opening / closing body 10 can be quickly opened and the object X can be easily removed. In particular, for example, even when urgency is required to remove the object X, the movable seat 13 (operated part A) can be used without the operator moving to a place where the operation switch is located or searching for a remote control device. Can be quickly operated, and the operability at that time is also good.

  Note that, according to the control example shown in FIG. 4, the control unit 34 opens the opening / closing body 10 while the opening / closing body 10 is stopped halfway if the operation signal from the operated part A is even once. As another example, the processing may be advanced to the next step 5 on condition that the operation signal from the operated part A is received a predetermined plural times or more in a predetermined time in the above step 4. . According to this configuration, the opening / closing body 10 is opened by a conscious operation of lifting the movable seat plate 13 a plurality of times. Therefore, the conscious multiple operations as described above are distinguished from, for example, a case where the operated part A reacts to an obstacle, or a case where the operated part A reacts erroneously due to a strong wind. Is possible.

  Next, another control example (see FIGS. 5 to 7) of the switchgear 1 will be described. Since this control example is obtained by partially changing the flowchart of FIG. 4 by changing the control program of the control unit 34, the changed part will be mainly described in detail, and overlapping detailed description will be omitted as appropriate.

  In the control example shown in FIG. 5, after performing steps 11 to 14 that are substantially the same as steps 1 to 4 (see FIG. 4), the opening operation of the opening / closing body 10 is started in step 15.

  Then, in the next step 16a, it is determined whether or not there has been an operation signal for the movable seat 13 (operated part A) during the opening operation of the opening / closing body 10, and if there is an operation signal, the next step If not, the process proceeds to step 16b.

In step 16b, it is determined whether or not the opening operation time of the opening / closing body 10 has passed a predetermined time. If the predetermined time has passed, the process proceeds to the next step 17; otherwise, the process proceeds to step 16a. return.
Here, the opening operation time is a time elapsed from the time when the opening / closing body 10 starts the opening operation, and is counted by a timer function (not shown) included in the control unit 34.

  In step 17, the opening operation of the opening / closing body 10 is stopped, and the process returns to step 11.

  Therefore, according to the control example shown in FIG. 5, when the movable seat plate 13 (operated part A) is operated while the opening / closing body 10 is stopped at the opening / closing position, the opening / closing body 10 is opened. Furthermore, when the movable seat plate 13 (operated part A) is operated again during the opening operation, or when the opening operation time has passed a predetermined time, the opening operation is performed. Can be stopped. As a result, the operability when the opening / closing body 10 stops at a position in the middle of opening / closing can be further improved.

In the control example shown in FIG. 6, after performing steps 21 to 23 substantially the same as steps 1 to 3 (see FIG. 4), in step 24, the number of operation signals of the operated part A is counted. The process proceeds to the next step 25.
Describing step 24 in detail, the control unit 34 operates a timer function (not shown) for a predetermined time, and the number of times the movable seat 13 is operated within the timer operation time (that is, the operated portion A). The number of operation signals from (1) is counted and stored in a storage device (not shown). After the count, the process proceeds to the next step 25.
Here, the predetermined time (the timer operating time) is a time set to about several seconds (for example, about 1 to 3 seconds). That is, for example, if the movable seat 13 is operated twice within a few seconds, the number of times (twice) is stored.

  In step 25, it is determined whether or not the number of operation signals counted in step 24 is greater than 0. If greater than 0, the process proceeds to the next step 25a; If so, the process returns to step 21.

In step 25a, it is determined whether or not the number of operation signals counted in step 24 is a first reference value (for example, one time). If not (for example, twice or more), the process proceeds to step 25b.
In step 26a, as in step 5 (see FIG. 4), the opening / closing body 10 is opened for a predetermined time (predetermined amount) and stopped, and the process returns to step 21.

In step 25b, it is determined whether or not the number of operation signals counted in step 24 is a second reference value (for example, twice). The process proceeds to step 26b. Otherwise, the process proceeds to step 26c.
In step 26b, the opening / closing body 10 is opened to the fully open position and stopped, and the process returns to step 21. The opening / closing body 10 is stopped at the fully opened position based on a sensing signal from the opening / closing position detecting means 35.

  In step 26c, the opening / closing body 10 is closed to the fully closed position and stopped, and the process returns to step 21. The opening / closing body 10 is stopped at the fully closed position based on a sensing signal from the opening / closing position detecting means 35.

  Therefore, according to the control example shown in FIG. 6, different controls are performed according to the number of operations on the movable seat 13 (operated portion A) within a predetermined time (the number of operation signals received by the control unit 34 within the predetermined time). The convenience of the opening / closing device 1 can be further improved.

In the above-described embodiment, the same operation signal is generated regardless of the rising amount of the movable seat plate 13 relative to the opening / closing body main body 11. However, as another example, the movable seat relative to the opening / closing body main body 11 is provided. Different operation signals may be issued from the operated portion A according to the amount of the plate 13 raised, and the control unit 34 may perform different control according to the operation signal.
More specifically, in the other example, the lower end side of the opening / closing body 11 has a structure substantially the same as that of the movable seat plate detection sensor 42f. A second sensor located on the upper side is provided, and the swing piece 14 can be sensed by each of these two sensors, and the control unit 34 applies the sensed sensor as shown in the control example of FIG. Different control is performed accordingly.

More specifically, in the control example shown in FIG. 7, after performing steps 31 to 33 substantially the same as steps 1 to 3 (see FIG. 4), in step 34, the stop time of the opening / closing body 10 is predetermined. It is determined whether or not the operable time has been exceeded. If the operable time has not been exceeded, the process proceeds to the next step 35; otherwise, the process returns to step 31.
Here, the stop time is a time elapsed from the time when the opening / closing body 10 stops the closing operation, and is counted by a timer function inherent in the control unit 34.
In addition, the operable time in step 34 is appropriately set so as to prevent the crime prevention performance from being lowered or the opening / closing operation by mischief is performed by leaving the open / closed body 10 in the midway open stop state for a long time. Is set.

  In step 35, it is determined whether or not there is a sensing signal from the first sensor located on the lower side. If there is a sensing signal, the process proceeds to the next step 36, and if not, the process proceeds to step 31. return.

  In step 36, it is determined whether or not there is a sensing signal from the second sensor located on the lower side. If there is a sensing signal, the process proceeds to step 36a; otherwise, the process proceeds to the next step 36b. Transition.

In step 36a, the opening / closing body 10 is opened to the fully open position and stopped. In step 36b, the opening / closing body 10 is opened for a predetermined time and stopped.
Then, after the opening / closing body 10 is stopped, the process returns to step 31.

  Therefore, according to another example of the opening / closing device shown in FIG. 7, when the rising amount of the movable seat 13 is relatively small, the opening / closing body 10 opens the predetermined amount based on the detection of only the first sensor. After that, when the movable seat plate 13 is lifted by a relatively large amount, the opening / closing body 10 opens to the fully open position and stops based on the detection by the first and second sensors. That is, different control operations can be performed by adjusting the contact operation with respect to the movable seat plate 13, and the convenience can be further improved.

As an example other than the illustrated example, in the control examples shown in FIGS. 4, 5, and 6, as with the control example in FIG. 7, the stop time at the halfway open position of the opening / closing body 10 is a predetermined operation. Predetermined control may be performed on condition that the allowable time has not been exceeded (see step 34).
Furthermore, a plurality of control examples shown in FIGS. 4 to 7 can be appropriately combined as necessary.

  Further, as a control example other than the illustrated example, a mode in which predetermined control other than the illustrated example is performed when the operation signal from the operated part A is received in a state where the opening and closing body 10 is stopped at the opening and closing position. It is also possible to do. In this case, a specific example of the predetermined control other than the illustrated example includes transmission of an alarm (including sound, light, signal, etc.) by an alarm device (not shown).

In the above embodiment, while the opening / closing body 10 is stopped in the middle of opening / closing, the predetermined control is performed by the contact operation with respect to the movable seat plate 13, but as another example, the proximity operation is performed instead of the contact operation. It is possible to adopt a mode in which the predetermined control is performed, a mode in which the predetermined control is performed in any of the contact operation and the proximity operation, and the like.
Furthermore, as another example, an operation part (for example, a sensor or an operation switch) that is separate from the movable seat plate 13 and the object detection means 40 is provided on the closing direction end of the opening / closing body 10. It is also possible to adopt a mode in which the predetermined control is performed by a contact operation or a proximity operation on the part.

  Moreover, in the said Example, as the object detection means 40, the structure which carries out non-contact detection (the discharge | release part 41b and the capture part 42b) of the object X, and the structure which carries out contact detection (movable seat board detection sensor 42f) of the same object X. Although used together, as another example, it is also possible to delete one of them and perform the sensing operation of the object X and the above-described contact operation or proximity operation only by the other.

  Moreover, in the said Example, although it was set as the aspect which transmits the signal of the to-be-operated part A, the object detection means 40, etc. to the control part 34 by wire, as another example, the aspect which transmits the said signal to the control part 34 wirelessly. It is also possible.

Further, as a preferable configuration added to the above-described embodiment, the control unit 34 has the drive source 33 when there is a fully-closed detection signal by the opening / closing position detection means 35 and the operation signal by the operated unit A is received. The opening / closing body 10 is configured to perform a closing operation by driving and rotating in the closing direction.
According to this configuration, for example, when there is an action such as opening and closing the opening / closing body 10 when fully closed, the opening / closing body 10 is forcibly closed to improve crime prevention.

  Moreover, according to the said Example, although the shutter curtain formed by connecting several slats as an example of the opening / closing body 10 was shown, as another example of this opening / closing body 10, a single or several panel, sheet form, etc. were shown. It is good also as an aspect formed by arrange | positioning a thing and a net-like thing in an opening-and-closing direction, or an aspect which combines a slat, a panel, a pipe, a sheet-like thing, a net-like thing, etc. suitably.

  Further, in the above embodiment, the operated portion A or the like that can be contacted or moved closer to the closing direction end of the opening / closing body 10 is applied to the shutter device of the illustrated example, but as another example, the operated portion A Etc., other shutter devices including overhead doors, sliding doors including shutters, sash windows, roll screens, blinds, gates, gates, sliding wall devices, etc. It is also possible to apply to a switchgear.

In addition, as another example when the crime prevention function is also expected in the opening / closing device 1, the opening / closing body 10 is within a predetermined range near the fully closed position (in other words, within a predetermined halfway opening range with a relatively small opening amount). If the opening / closing body 10 is stopped and the opening / closing body 10 is stopped, even if the operation signal from the operated part A is received, the opening state is not performed and the stop state is continued. It is also possible to do so.
The predetermined range is, for example, within a range in which the height between the lower end of the opening / closing body 10 and the contact target portion p is a height that does not allow a person to go through, or a height that cannot be lifted by a bar or the like. Yes, as a specific example, the height may be 40 cm or less, and this height can be arbitrarily set as long as there is no problem in crime prevention.

  Furthermore, from the viewpoint of crime prevention, when the opening / closing body 10 is stopped within the predetermined range (height), even if there is an operation signal from the operated part A, the opening operation is not performed, and It is possible to actively maintain the height position during the stop by the operation of the drive source 33, or to forcibly close the opening / closing body 10 to the fully closed position.
