The open / close door device includes a balance door and a folding door. Etc., but not including sliding doors, sliding doors, revolving doors, etc.

  The door body includes both a hanging door body that is hung from above and opened and closed, and a door body that opens and closes along the lower rail, but requires unevenness on the floor surface or the like. The former is preferable because it can improve the trafficability.

  The immovable part may be an immovable part relative to the moving support part moving in the width direction of the opening. Examples of the immovable part include a frame member around the door body and the opening / closing. Includes a housing that is an installation object of the door device.

  Further, the width direction of the opening is a horizontal width direction of the opening that is opened and closed by the door body, and is not the rotational axis direction of the door body.

Moreover, the said movement support part should just be supported so that it may be provided so that it may move to the width direction of an opening part with respect to a stationary part, and the said door body may be rotated in the direction which cross | intersects an opening part. .
As a specific means for moving the moving support portion in the width direction of the opening with respect to the stationary part, a rail-like member is provided along the width direction of the opening on the stationary part side or the door body side. What is necessary is just to set it as the structure etc. which a movement support part moves along.

The linear motor may be a general linear motor in which the mover is propelled by a magnetic field generated from the stator.
In addition, although the said mover includes both the aspect comprised from a permanent magnet, and the aspect comprised from an electromagnet, the former aspect is more preferable from omitting an electric wire etc.

The moving support portion and the linear motor are preferably provided on the upper side of the door body, but may be configured on the lower side of the door body.
Further, the position of the linear motor in the thickness direction of the door body is largely separated from the movement locus of the movement support part, and there is no case where a driving force for moving the movement support part cannot be obtained. The position is arbitrary, and preferably a position on the trajectory of the movement support portion.

  Further, in the second invention, sensing is performed for sensing one or both of a state in which the door body is opened by a predetermined amount from the fully closed position and a state in which the door body is closed by a predetermined amount from the fully opened position. And the linear motor is changed from a non-energized state to an energized state in accordance with a sensing signal of the sensing unit, and the movement of the movable support is continued.

Here, the sensing unit may be any sensor that can sense the movable element or a part that moves integrally with the movable element. For example, the sensing part may be a contact type sensor such as a limit switch or a micro switch. And non-contact sensors such as proximity switches and photoelectric switches.
There may be a single sensing unit or a plurality of sensing units. That is, a single identical sensing unit includes a sensing unit that senses a state in which the door is opened by a predetermined amount from the fully closed position, and a sensing unit that senses a state in which the door is closed by a predetermined amount from the fully opened position. Or a plurality of separate sensing units.

In the third aspect of the invention, a plurality of door bodies are provided in the width direction of the opening, and one of the adjacent door bodies is bi-directionally rotated with respect to the other of the plurality of door bodies. connection,
While supporting the door body on the farthest door side by the above movement support part, and supporting the door body on the outermost door side so as to be rotatable with respect to the immovable part, it constitutes a folding door part that can be double-opened. Features.

  According to a fourth aspect of the invention, the mover is provided so as to protrude from the movement support portion in the movement direction during the door closing operation.

  Further, the fifth invention is characterized in that when the door body is fully closed, the fully closed state is maintained by the driving force of the linear motor.

  Further, the sixth invention is characterized in that the controller unit of the linear motor is disposed outside the moving range of the moving support unit.

  Here, the said controller part is a structure provided with the control circuit which has a function for controlling the said linear motor part, and is electrically wired with respect to the said stator.

  In the seventh aspect of the invention, the stator is placed in the center of the movement range of the movement support portion so that the stator and the movable element do not face each other when the door member is in the fully closed position or the fully open position. It is characterized by being placed close to the side.

  That is, according to the seventh aspect of the invention, the length of the stator is shorter than the length of the moving range of the moving support portion, and the stator is moved closer to the center in the moving range of the moving support portion. Be placed.

  In the eighth invention, when the movement support member is positioned within a predetermined range during the closing operation of the door member, the linear motor is controlled in power so as to reduce the speed of the mover. Features.

Here, the predetermined range is a specific range that is set on the side of the moving direction of the moving support member in accordance with the closing operation of the door member.
As a preferable specific example of the predetermined range, a range just before the door member during the closing operation is almost completely closed is set in the moving range of the moving support member.

  The power control of the linear motor for reducing the speed of the mover includes means for reducing the voltage of the power supply to the linear motor, reducing the frequency of the power supply, and the like.

  The ninth invention is characterized in that a damper device is provided so as to further reduce the speed of the mover when the door member reaches a predetermined position within the predetermined range. The opening / closing door apparatus of any one of thru | or 8.

Here, the damper device may be configured to reduce the speed of the mover, and the damper device includes a member integrated with the mover or the mover, a biasing member or a compressible fluid. It is incorporated in the shaft support part that supports the door bottom side of the door body and the aspect that is elastically received by the elastic force of the door body, and the rotation of the door body is eased by the biasing force of the biasing member, etc. Including embodiments.
Furthermore, the damper device may be configured such that resistance is simply given to the movement of the mover by friction or the like.

Since the present invention is configured as described above, the following effects can be obtained.
According to the first invention, since the door body is opened and closed by moving the moving support portion with a linear motor, the driving mechanism is compared with the conventional technique including a pulley, a belt, and a driving device. It is possible to reduce the space for providing, and as a result, the door device can be miniaturized.
In addition, for example, even when the power supplied to the linear motor is interrupted due to a power failure or the like, the door can be opened and closed with a relatively light manual opening and closing force.
In addition, for example, even when the door body during the closing operation is to be stopped by hand, the manual stop operation can be easily performed.
Furthermore, even if the door body in the closing operation comes into contact with an object or the like about to pass through the opening, the impact at the time of the contact can be made relatively light.
Therefore, it is possible to provide an opening / closing door device that is convenient for opening / closing operations with a space-saving drive source configuration.

Further, according to the second invention, if the door body in the fully closed position is opened by a predetermined amount by manual operation or the door body in the fully open position is closed by a predetermined amount by manual operation or the like, Even if the operation is released, the subsequent operation of the door body can be continued by driving the linear motor.
That is, according to the present invention, the door body is automatically opened by an operation of manually opening the door body in the fully closed position, or the door body is automatically opened by an operation of manually closing the door body in the fully open position. It can be closed.

  Furthermore, according to the third invention, the convenience of the opening / closing operation can be further improved with the configuration of the space-saving drive source.

  Furthermore, according to the fourth aspect of the present invention, since the movable element, the stator, and the like are not arranged at the door-side portion in the fully open state of the door body, it is possible to improve the maintainability.

  Furthermore, according to the fifth invention, there is no need to have a locking structure for maintaining the fully closed state of the door body, and the closing performance when the door body is fully closed is determined by the driving force of the linear motor. It can be maintained well.

  Furthermore, according to the sixth invention, it is possible to prevent the movement of the movement support portion in the opening width direction from being hindered by the controller portion.

Furthermore, according to the seventh invention, when the door body is in the fully closed position or the fully open position, since the stator and the movable element do not face each other, even if the linear motor is energized, the movement support portion Can be maintained (in other words, the door is stopped).
When the door is slightly opened from the fully closed position, or slightly closed from the fully opened position, the stator and the mover face each other due to the movement of the moving support portion accompanying the operation. The door can be closed or opened by continuously moving the moving support portion by the driving force of the linear motor.
Therefore, according to the present invention, there is no need to separately provide a sensor for detecting that the door body at the fully closed position is slightly opened or a sensor for detecting that the door body at the fully opened position is slightly closed. The door body that has been slightly opened can be automatically opened as it is, or the door body that has been slightly manually closed can be automatically closed as it is.

Furthermore, according to the eighth invention, when the door body approaches the fully closed position, the speed of the mover decreases due to the electric power control of the linear motor. Adjusted to the correct speed.
That is, normally, the door member during the closing operation is accelerated as the moving speed on the door end side approaches the fully closed position by the combined movement of the movement in the width direction of the opening and the rotation. According to the above, it is possible to prevent the acceleration on the door end side as described above, and as a result, the door body during the closing operation exceeds the fully closed position (in the case of double opening type), or the door holding member in the fully closed position. It is possible to prevent a strong collision (such as in the case of a single-opening type) or the like, and it is also possible to reduce an impact when the door body contacts an object or the like.

  Furthermore, according to the ninth aspect, the shock when the door member is fully closed can be effectively prevented by the damper device.

  The movement support portion 41 includes a shaft portion 41a (see FIG. 2) that rotatably suspends the door body 11 on the door end side, a support bracket 41b fixed to the upper side of the shaft portion 41a, and the support The suspension wheels 41c and 41c are rotatably supported by a bracket 41b. The shaft portion 41a is attached to the door body 11 so as not to move in the width direction.

  The shaft portion 41a supports the door body 11 through a bearing or the like so as to open and close.

The support bracket 41b fastens the shaft 41a to the lower side and supports the suspension wheel 41c to rotate along the opening width direction on the upper side.
The support bracket 41b is made of a magnetic metal material, and functions as an attracted body that is magnetically attracted by a magnetic attracting body 43 described later.
As another example of the attracted body, the support bracket 41b itself is configured as a magnet that attracts the magnetic attracting body 43, or the portion of the support bracket 41b facing the magnetic attracting body 43 is magnetically attracted. It is good also as a structure etc. which provided the magnet so that the body 43 might attract | suck.

  In addition, the suspension vehicle 41c is supported by the support bracket 41b so as to roll on the guide rail 42. According to the illustrated preferred example, the number of the suspension vehicles 41 is two, but the number is one or three or more. Is also possible.

  The guide rail 42 is disposed so as to receive the suspension wheel 41 c from the lower side and guide it in the width direction of the opening, and is fixed to the upper frame portion 23.

Further, a magnetic attracting body 43 is provided on the door end direction side (left direction side in FIG. 2) from the support bracket 41b when the folding door portion 10 is substantially fully closed.
The magnetic attracting body 43 is a so-called permanent magnet, is disposed so as to face the end of the support bracket 41b on the door-end direction side, and is fixed to the upper frame portion 23, which is an immobile portion, via a bracket or the like. ing.

  Note that reference numeral 44 in FIG. 2 denotes a contacted portion that is contacted by the support bracket 41b when the door body 11 is substantially fully opened. The contacted portion 44 receives an impact at the time of contact. A buffer material such as an elastic body is fixed to the contact surface so as to relax.

  The linear motor 49 supplies power to the stator 49a fixed to the upper frame portion 23, which is a stationary part, the mover 49b fixed to the movement support portion 41, and the stator 49a. And a controller unit 49c for controlling.

The stator 49a is a coil unit in which a coil for providing a propulsive force in the opening width direction to the movable element 49b is contained, and electric power is supplied to the coil from a controller unit 49c outside the stator 49a.
The stator 49a is formed in a long shape extending in the width direction of the opening, and one end portion of the stator 49a is used as a movable element 49b when the folding door 10 is substantially fully closed (the state shown in FIG. 2A). The other end side portion is fixed to the upper frame portion 23 so as to face the movable element 49b when the folding door portion 10 is substantially opened (the state shown in FIG. 2B). .

One or more sensing portions 49a1 capable of sensing the mover 49b are provided in the middle of the length of the stator 49a.
The sensing unit 49a1 is a proximity switch that senses the mover 49b when the door body 11 is opened by a predetermined amount from the fully open position or when the door body 11 is closed by a predetermined amount from the fully open position. The signal is transmitted to the controller unit 49c.
A single sensing unit 49a1 is provided at substantially the center in the length direction of the stator 49a so that the door body 11 is closed by a predetermined amount from the fully open position, and the door body 11 is opened by a predetermined amount from the fully closed position. Both of the states may be sensed at the same location, or a plurality of them may be sensed at different locations in the middle of the length of the stator 49a. .
The sensing unit 49a1 is a contact type switch (for example, a non-contact sensor other than the proximity switch (for example, a photoelectric switch) or a contact switch (for example, a support bracket 41b or the like) that is integrated with the movable element 49b. It is also possible to replace it with a limit switch.

The mover 49b is a stator of a linear motor composed of permanent magnets. When facing the stator 49a, an appropriate clearance is secured between the mover 49b and the stator 49a, and the support bracket 41b. It is being fixed to the upper end of the opening part width direction.
In addition, since the larger driving force by a linear motor is obtained, so that the said clearance is small, consumption of the electric power with respect to a required driving force can be suppressed by adjusting the said clearance suitably.

The controller unit 49c includes a control circuit (not shown) including a plurality of electronic components, an integrated circuit board, and the like, and controls the electric power supplied from the outside and outputs it to the stator 49a.
More specifically, the controller unit 49c appropriately maintains the moving speed of the mover 49b and the movement support unit 41, changes the moving direction of the mover 49b, and stops the movement of the mover 49b. The output power is controlled such that

  The controller 49c configured as described above is disposed outside the movement range of the movement support 41 so as not to hinder the movement of the movement support 41. According to the illustrated example, the stator 49a and the guide rail 42 are arranged. It is being fixed to the upper frame part 23 rather than the door-end side.

Next, the characteristics of the opening / closing operation of the door device 1 will be described in detail with reference to FIGS.
First, when the user or the like slightly closes the folding door portion 10 in the fully opened state by manual operation or the like, the sensing portion 49a1 in the stator 49a is moved by the movement of the movement support portion 41 and the movable portion 49b accompanying the operation. The child 49b is sensed. Then, according to the sensing signal, the controller unit 49c supplies power to the stator 49a so as to propel the stator 49a.
Accordingly, the folding operation of the folding door 10 is continued by driving the linear motor 49.
When the folding door 10 is fully closed, the controller 49c stops supplying power to the stator 49a.
The means for detecting that the folding door 10 is fully closed may be configured to detect by a contact type or non-contact type sensor (not shown), and the electric current value supplied to the stator 49a has a predetermined value. It is good also as a structure which recognizes that it exceeded.

  The fully closed state of the folding door 10 is maintained by the support bracket 41 b being attracted to the magnetic attracting body 43.

Further, when the user or the like slightly opens the folding door portion 10 in the fully closed state, the sensing portion 49a1 in the stator 49a causes the movable portion 49b to move due to the movement of the moving support portion 41 and the movable portion 49b. Sense. And according to the sensing signal, the controller unit 49c supplies electric power to the stator 49a so as to propel the mover 49b in the direction opposite to that when the door is closed.
Therefore, the folding door unit 10 is continuously opened by driving the linear motor 49.

When the folding door part 10 is substantially fully opened by the movement support part 41 coming into contact with the contacted part 44, the controller part 49c stops supplying power to the stator 49a.
The means for detecting that the folding door portion 10 is fully opened may be configured to detect by a contact type or non-contact type sensor (not shown), or recognized when the current value of the stator 49a exceeds a predetermined value. It is good also as a structure.
Further, in order to change the propulsion direction of the mover 49b, a means for changing the propulsion direction in a general linear motor may be used. In this embodiment, the phase of the electric power supplied from the controller unit 49c to the stator 49a is used. Is converted.
The timing for converting the phase may be the time when the folding door 10 is fully opened or fully closed, but may be delayed using a timer or the like.

Thus, according to the open / close door device 1 configured as described above, since the folding door 10 is opened and closed by the linear motor 49, the drive source is compared with a mechanism including a pulley, a belt, and a drive device. Therefore, the space for providing the space is small, and the upper frame portion 23 can be downsized.
In addition, even when the power supplied to the linear motor 49 is interrupted due to a power failure or the like, the resistance on the drive source side is relatively small, so that the folding door 10 can be easily opened and closed manually.
In addition, the folding door 10 during the closing operation can be stopped with a relatively light force by the linear motor 49, and the impact when the folding door 10 during the closing operation comes into contact with an object or the like is relatively small. That's it.

  Next, another example of the open / close door device according to the present invention will be described. In addition, since the door apparatus shown below is comprised by changing the said door apparatus 1 partially, it attaches | subjects the same code | symbol about the location substantially the same as the said door apparatus 1. FIG. The detailed description which overlaps with is omitted.

In the opening / closing door device 2 shown in FIG. 4, the movable element 49 b protrudes from the movement support portion 41 in the movement direction (leftward according to FIG. 4) when the door body is closed. The stator 49a is arranged on the side.
If it demonstrates in detail, the needle | mover 49b in this opening-and-closing door apparatus 2 will protrude in the moving direction at the time of a door body closing from the support bracket 41b by being fixed to the support bracket 41b via another bracket etc. To be arranged.
As shown in FIG. 4, the projecting amount of the movable element 49b may be such that the entire movable element 49b is positioned closer to the moving direction side when the door body is closed than the support bracket 41b. Good.
The stator 49a is arranged so as to correspond to the moving range of the movable element 49b. Therefore, the stator 49a and the movable element 49b are not positioned in the door-side space S in the upper frame portion 23.

Thus, according to the open / close door device 2, since the stator 49a and the movable element 49b are not located in the space S on the door bottom side, maintenance work and the like for the stator 49a and the movable element 49b can be easily performed. Can do.
That is, for example, as shown in FIG. 4B, the stator 49 a and the movable element 49 b are not positioned above the folding door part 10 and the movement support part 41 even when the folding door part 10 is substantially fully opened. The maintenance work for the stator 49a and the movable element 49b is good.

In the open / close door device 3 shown in FIG. 5, the magnetic attracting body 43 and the elastic body 43 b are omitted from the open / close door device 1, and when the folding door portion 10 is substantially fully closed, the fully closed state of the linear motor 49 is changed. It is maintained by the driving force. Further, even when the folding door portion 10 is substantially fully opened, the fully opened state is maintained by the driving force of the linear motor 49.
The specific means for maintaining the fully closed state of the folding door 10 by the driving force of the linear motor 49 recognizes that the folding door 10 has been substantially fully closed by the closing operation by the sensing unit 49a1, sensing means (not shown), or the like. In such a case, the energization to the linear motor 49 should not be cut off.
In a similar manner, the specific means for maintaining the fully opened state of the folding door 10 by the driving force of the linear motor 49 is that the folding door 10 has been brought into the substantially fully opened position by the opening operation, such as a sensing unit 49a1 or sensing means (not shown). When it is recognized by the above, it is sufficient that the energization to the linear motor 49 is not cut off.
Note that, as a more preferable aspect, when the energization of the linear motor 49 is maintained in the fully open state or the fully closed state of the folding door portion 10 as described above, the controller portion 49c is configured so that the energization power is minimized. The output voltage and output frequency are adjusted appropriately.
Moreover, in the said aspect, although energization to the linear motor 49 is continuously maintained in the fully open state or the fully closed state of the folding door portion 10, as another example, the above described in the fully open state or the fully closed state of the folding door portion 10 Even if the electric power is cut off, if the fully open or fully closed state of the folding door 10 can be maintained by the frictional force or the like at each contact location, the energization time may be a temporary time within a predetermined time. Is possible.

6 is replaced when the door body 11 is in the fully closed position and the fully open position by replacing the stator 49a with the stator 49a ′. The child 49a ′ and the movable element 49b are not opposed to each other, and the sensing unit 49a1 is omitted.
More specifically, the stator 49a ′ is configured to be shorter than the stator 49a in the open / close door device 1 so as not to face the movable element 49b when the door body 11 is in the fully closed position or the fully open position. Then, it is arranged close to the center side in the movement range of the movement support part 41.

That is, when the door body 11 is in the fully closed position or the fully open position, the stator 49a ′ is not positioned above the movable element 49b, and when the door body 11 is in a position other than the fully closed position and the fully open position, the door body 11 is movable. The relationship is such that the stator 49a 'is positioned above the child 49b.
The driving power from the controller 49c to the stator 49a ′ is always supplied regardless of whether the door body 11 is in the fully closed position or the fully open position.
In addition, when the door body 11 is in the fully open position, the drive power is switched so that the movable element 49b is propelled in the door end direction (left direction in FIG. 6), and the door body 11 is in the fully closed position. In some cases, the supply is switched so that the mover 49b is propelled in the door butt direction (right direction in FIG. 6).

Thus, according to the open / close door device 4 shown in FIG. 6, for example, when the folding door portion 10 in the fully closed position is to be opened, if the door body 11 is slightly opened manually, Along with the opening operation, the movement support portion 41 and the movable element 49b move in the door bottom direction.
When the mover 49b moves to a position facing the stator 49a ′, the mover 49b continues to move further due to the electromagnetic propulsive force received from the stator 49a ′.
When the folding door 10 is in the fully open position, the mover 49b and the stator 49a ′ do not face each other, so the mover 49b does not receive electromagnetic propulsion from the stator 49a.

Further, when the folding door portion 10 in the fully open position is to be fully closed, if the door body 11 is slightly closed manually by the reverse action, the movable element 49b is moved along with the manual closing operation. The movable element 49b moves to a position facing the stator 49a ′, and the movable element 49b continues to move further due to the electromagnetic propulsive force received from the stator 49a ′.
When the folding door 10 is in the fully closed position, the mover 49b and the stator 49a ′ do not face each other, so the mover 49b does not receive electromagnetic propulsive force from the stator 49a ′.

  The opening / closing door device 4 may be configured so that the stator 49a ′ is always energized. However, the sensor 49 detects that the stator 49a ′ and the mover 49b are opposed to each other, and there is a detection signal. It is also possible to control the stator 49a ′ to be in an energized state only when

Further, according to the open / close door device 4 illustrated in FIG. 6, the stator 49 a ′ and the movable element 49 b do not face each other when the door body 11 is in the fully closed position and the fully open position. As another example, when the door body 11 is in one of the fully closed position and the fully opened position, the stator 49a ′ and the movable element 49b can be prevented from facing each other.
In this case, when the door body 11 is in the fully open state or the fully closed state, the timing at which the phase of the electric power supplied to the stator 49a is converted to change the propulsion direction of the movable element 49b is such that the folding door 10 is fully opened. However, it is possible to use a timer or the like to delay the state.

In addition, the open / close door device 5 shown in FIG. 7 has a predetermined range on the door end side (left side in FIG. 7) in which the movement support portion 41 is propelling the sensing portion 49a1 in the door end direction in the configuration of the door device 1 described above. It is used as a means for sensing that it is located in W, and the propulsion speed of the movable element 49b is reduced according to the sensing signal of the sensing part 49a1.
In this open / close door device 5, the sensing portion 49a1 is disposed at a position away from the door end side end portion of the stator 49a ′ by a predetermined distance (predetermined range W) to the door bottom side (right side in FIG. 7).
The predetermined range W is appropriately set so as to decelerate the closing operation of the folding door portion 10 near full closure.
The sensing unit 49a1 has a function of sensing the mover 49b when a manual opening operation or a manual closing operation is performed, and a function of sensing that the mover 49b propelled toward the door end is positioned within the predetermined range W. Or a plurality of the functions may be allocated to each of them.
In addition, whether the folding door 10 and the movement support unit 41 are propelled in the door tip direction or the door bottom direction can be determined from the electric power phase or the detection signal from the sensor or the like. Judgment may be made.

The flowchart of FIG. 8 shows a control operation by the controller unit 49c during the closing operation of the folding door unit 10 in the open / close door device 5.
In step 1 in this flowchart, it is determined whether or not the movement support portion 41 is located within the predetermined range W during the closing operation of the door body 11. If not, the process waits until the movement support unit 41 is located within the predetermined range W.
That is, according to this step 1, when the movement support part 41 and the movable element 49b are propelled toward the door end in accordance with the closing operation of the door body 11, it is determined whether or not the movable element 49b is sensed by the sensing part 49a1. To be judged.

In step 2, the propulsion speed of the mover 49b is reduced by power control by the controller unit 49c.
Specifically, the propulsion speed of the mover 49b is reduced by controlling the voltage and / or frequency of the power supplied from the controller unit 49c to the stator 49a.

Next, in step 3, it is determined whether or not the door body 11 is fully closed. If the door body 11 is fully closed, the process proceeds to the next step 4 to turn off the linear motor 49, and so on. If not, step 3 is repeated until the door 11 is fully closed.
The means for detecting that the door body 11 is fully closed includes, for example, a moving support portion 41 or a member integrated with the moving support portion 41 when fully closed by a contact or non-contact type sensor (not shown). It may be configured to detect, or may be configured to recognize that the current value when fully closed exceeds a predetermined value.

Thus, according to this open / close door device 5, when the door body 11 approaches the fully closed position, the speed of the movable element 49 b decreases due to the power control on the linear motor 49. The moving speed of the front portion 10a is adjusted to an appropriate speed.
That is, as shown in FIG. 3, the door body 11 that is normally in the closing operation has a combined movement of the movement in the opening width direction and the rotational movement, and the speed of the door tip portion 10a approaches the fully closed position. Although accelerated, according to the present invention, it is possible to prevent the acceleration of the door tip portion 10a as described above, and thus, the door body 11 during the closing operation is prevented from exceeding the fully closed position. In addition, even if the door tip portion 10a comes into contact with an object or the like, the impact at the time of contact can be reduced.

Next, the opening / closing door device 6 shown in FIG. 9 will be described.
The open / close door device 6 has a configuration in which a mechanical damper device 50 is added to the open / close door device 5.
The damper device 50 is a known mechanism that biases the piston portion 51 in the extending direction. According to the illustrated example, the piston 51 is configured to be biased in the extending direction by the spring 52, but other examples include a configuration in which the piston 51 is biased by the elasticity of gas in the cylinder 53, It is possible to adopt a known configuration.
The damper device 50 is fixed to the upper frame portion 23 so that the moving support portion 41 is received by the protruding end portion of the piston portion 51 from the door tip side slightly before the folding door portion 10 is substantially fully closed. Has been.

According to this open / close door device 6, substantially like the open / close door device 5, the moving support portion 41 and the mover 49 b are decelerated by power control of the controller portion 49 c slightly before the folding door portion 10 is fully closed. Furthermore, the closing operation of the folding door part 10 is also decelerated by the movement support part 41 being received by the piston part 51.
And the folding door part 10 at the time of full closure will maintain the full closure state because the support bracket 41b is adsorb | sucked to the magnetic attraction body 43. FIG.
Further, when the folding door 10 in the fully closed state is opened, if the user or the like manually operates the door body 11 slightly in the opening direction, the initial driving force by the linear motor 49 is applied to the elastic force of the damper device 50. Assisted by the generated force, the movement support unit 41 and the mover 49b are smoothly moved in the door bottom direction (right direction in FIG. 9).

  In the opening / closing door device 6, the control for decelerating the movable element 49 b propelled toward the door end is omitted, and the folding door portion 10 at the time of the closing operation is decelerated only by the damper device 50 just before being fully closed. It is also possible to adopt a configuration in which

Further, according to the above-described open / close door devices 1, 2, 4, 5, 6 (see FIGS. 2, 4, 6, 7, 9), the support bracket 41b is attached to the magnetic attracting body 43 when the folding door portion 10 is fully closed. However, as another example, a gap is provided between the support bracket 41b and the magnetic attracting body 43 so that the attracting force of the magnetic attracting body 43 acts when the folding door 10 is fully closed. In addition, the elastic body 43b may be omitted.
Also with this configuration, the folding door 10 can be fully closed by the attractive force of the magnetic attracting body 43, and the impact when the support bracket 41b and the magnetic attracting body 43 come into contact can be reduced.

Further, as a configuration added to the above-described embodiment, when the folding door portion 10 in the closing operation comes into contact with an object or the like, the folding door portion 10 may be reversely operated (opening operation) or stopped. Specifically, it is only necessary to recognize from the change in the current value of the linear motor 49 that the folding door 10 that is in the closing operation has come into contact with an object or the like, and to reversely operate or stop the folding door 10.
According to this configuration, even if the folding door 10 in the closing operation comes into contact with an object or the like, the impact at the time of the contact is alleviated, and the object or the like is on the door end and the door end side of the folding door 10. It can prevent being pinched | interposed between the vertical frame parts 21. FIG.

  Moreover, according to the said embodiment, although it is set as the structure which carries out closing operation when the folding door part 10 at the time of full opening is manually closed a little, as another example, the folding door part 10 at the time of full opening is predetermined time. It may be configured to be automatically closed later.

  Moreover, as a structure added to the said embodiment, when the folding door part 10 is manually maintained by the half open state, it can also be set as the structure by which the half open state is hold | maintained.

  In addition, the operation pattern of the folding door 10 can be changed as appropriate by changing the control circuit of the controller 49c.

In addition, in each aspect shown in FIGS. 2, 4, 5, 7, and 9, the sensing unit 49a1 senses that the folding door 10 in the fully open state or the fully closed state has slightly moved by manual operation or the like. As another example, by detecting the induced electromotive force generated by the coil of the non-energized stator 49a as the mover 49b moves, the mover 49b is moved by an external force, that is, fully open or fully closed. It may be detected that the folding door portion 10 in a state is slightly moved by manual operation or the like, and electric power is supplied to the stator 49a according to the detection signal.
According to this configuration, regardless of the position at which the movement support portion 41 starts to move due to an external force, in other words, the position at which the folding door portion 10 starts the opening operation or the closing operation due to the external force, the state change can be performed. Sense and activate the linear motor.

Moreover, according to each said aspect, although the opening operation and closing operation | movement of the folding door part 10 are performed by the linear motor 49, while only one operation | movement is performed by the linear motor 49, the other operation | movement is carried out, Manual operation, operation by urging means, and the like are also possible.
Further, the operation by the linear motor 49 may be substantially the entire opening / closing range of the folding door 10 or may be a partial region within the opening / closing range.
