It is preferable that the storage unit detection sensor is disposed in a guide rail that guides in a direction.

The storage unit sensing sensor and the sensed unit may be singular or plural.
As a preferable example in which a plurality of the storage unit detection sensors and the sensed units are provided in the opening / closing body width direction, the storage unit detection sensor and the detection unit are provided at one end side and the other end side in the opening / closing body width direction. The aspect made to provide in each of these is mentioned.
According to this aspect, for example, even if the opening / closing body during the opening operation is in a one-down state (specifically, one end side in the width direction of the opening / closing body is lowered from the other end side), at least The corresponding sensed part can be sensed by one storage part sensing sensor.

Further, a plurality of storage unit detection sensors are provided in the opening / closing body opening / closing direction corresponding to a single detected part, and the plurality of storage unit detection sensors are arranged according to the position of the opening / closing body in the opening / closing direction.

This sensor unit may be provided only on one end side in the width direction of the opening / closing body, or may be provided on each of both end sides in the width direction of the opening / closing body.

In the present specification, the “opening / closing body thickness direction” means the thickness direction of the opening / closing body in the closed state.
Further, in this specification, the “opening / closing body width direction” means a direction that is substantially orthogonal to the opening / closing direction of the opening / closing body and not the thickness direction of the opening / closing body.
Further, in this specification, the “opening / closing body opening / closing direction” means a direction in which the opening / closing body slides in order to partition or open the space.

Since the present invention is configured as described above, the following effects can be obtained.
According to the first invention, since the storage unit detection sensor is arranged on the opening / closing body, it is not necessary to provide a space for installing the storage unit detection sensor on the storage unit side.

Therefore, for example, when the opening / closing body is slightly in front of the predetermined fully opened position, when the opening / closing body is substantially at the fully opened position, or when the opening / closing body exceeds the predetermined fully opened position, the predetermined control is performed. It can be carried out.

Further, according to the third aspect of the invention, the operation of the opening / closing body is stopped in response to the fact that the housing part detection sensor on the closing direction end of the opening / closing body senses the sensed part on the housing part side.
Therefore, for example, when an opening / closing body controlled to stop at a predetermined fully opened position does not stop at the fully opened position during an opening operation, the opening / closing body is urgently stopped and the opening / closing body ends in the closing direction. It is possible to prevent the part from entering the storage part side.
Further, for example, when an opening / closing body controlled to stop at a predetermined fully closed position does not stop at the fully closed position during the closing operation, the opening / closing body is urgently stopped and It can be prevented that the contacted portion (for example, a floor surface, the ground, or a frame member) is strongly pressed.

  Further, according to the fourth invention, since the storage unit detection sensor is a non-contact detection sensor, the contact of the storage unit detection sensor does not hinder the operation of the opening / closing body and hardly causes malfunction.

  Further, according to the fifth invention, since the sensor unit is structured to slide in the opening / closing body opening / closing direction while being supported by the guide rail, the storage unit detection sensor integrally provided in the sensor unit includes the opening / closing body. It can be prevented from being tilted or separated from the sensed part due to wind pressure received or vibration during opening / closing operation, and the sensing accuracy of the storage unit sensing sensor can be maintained well.

In addition, the said convex parts 12a1 and 12a1 can also be set as the aspect protruded from the surface and the back surface of the connection member 12, without using the said suspension bracket 12a.

The guide rail 20 is a member configured to surround an end of the opening / closing body 10 in the 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 storage unit 30.
And this guide rail 20 is supporting the sensor unit 50a (or 50b) mentioned later so that it may guide in the opening-and-closing body opening-closing direction in the inside.

And a control unit 34 for controlling the drive source 33 by processing sensing signals from sensor units 50a and 50b described later.

The storage case 31 is a substantially box-shaped member in which an opening 31a (see FIG. 3) for allowing the opening / closing body 10 to appear and disappear is formed on the lower side, and a storage portion described later is provided in the vicinity of the opening 31a. A sensed part 31b sensed by a sensing sensor 54 (see FIG. 2) is provided.
The sensed part 31 b is a metal substantially plate-like member, and is fixed to the inner wall of the storage case 31 with its substantially flat surface facing the surface of the opening / closing body 10 substantially in parallel.
In addition, according to the illustrated example, the sensed part 31b has a configuration in which a member separate from the storage case 31 is fixed to the storage case 31, but may be a part of the storage case 31 itself. .

  The sensor unit 50 a and the sensor unit 50 b are provided on both sides of the opening / closing body 10 in the width direction, and sense an object closer to the closing direction than the opening / closing body 10.

  One sensor unit 50a protrudes from the closing direction end of the opening / closing body in the opening / closing body closing direction, and retracts by contact with a contact target portion p (for example, a floor surface, the ground, a frame member, etc.). The slide body 51 provided, the discharge portion 52a that is provided on the projecting end side of the slide body 51 and discharges the object sensing medium s in the opening / closing body width direction, and the movable seat 13 are relative to the opening / closing body body 11 and the connection member 12. A movable seat plate sensor 53 that senses sliding in the opening / closing body opening direction, and a housing part sensor 54 that can sense the sensed part 31b (see FIG. 2).

  The other sensor unit 50b includes a slide body 51 configured substantially the same as that of the sensor unit 50a, a capturing unit 52b for capturing the object sensing medium s emitted from the emitting unit 52a, and the sensor unit. A movable seat plate detection sensor 53 and a storage portion detection sensor 54 are provided which are configured in substantially the same manner as that of the device 50a.

The electrical wiring on the sensor unit 50b side is inserted into the guide rail 20 and guided to the control unit 34 in the storage unit 30 by an electrical wiring guide member 56 supported via a bracket 55 and the like.
Further, according to the illustrated example, the electric wiring on the sensor unit 50a side is inserted into the sensor unit 50b side through the movable seat 13 or the connecting member 12, and is bundled with the electric wiring on the sensor unit 50b side. The guide rail 20 is inserted into the right guide rail 20 shown in the figure and connected to the control unit 34.
As another example, the electrical wiring on the sensor unit 50a side and the electrical wiring on the sensor unit 50b side are respectively inserted into the left guide rail 20 and the right guide rail 20 to the control unit 34. It is also possible to adopt a guiding structure.

  In the sensor unit 50a (or 50b), the concave grooves 51a and 51a in the slide body 51 are engaged with the convex portions 12a1 and 12a1 on the connection member 12 side. The sensor unit 50 a (or 50 b) is suspended in a substantially free-hanging manner relative to the opening / closing body 10 so as to slide in the opening / closing direction relative to the opening / closing body 10. By engaging the guide engaging portions 51e, 51e with a substantially convex rail portion (not shown) in the guide rail 20, the guide engaging portions 51e are supported so as to slide in the opening / closing body opening / closing direction.

If each part of the slide body 51 is demonstrated in detail, according to the example of illustration, each slide body 51 will exhibit the substantially hollow rectangular parallelepiped frame shape elongate to the up-down direction, and the opening / closing direction is opposed to the opening / closing body 10 in the inside. Are provided with concave grooves 51a, 51a engaged with the opening / closing body 10 so as to slide to the right.
Further, each slide body 51 includes guide engaging portions 51e and 51e on the bottom surface side of the guide rail 20 in both wall portions arranged so as to sandwich the opening / closing body 10, and a wall portion facing the bottom surface of the guide rail 20 Is provided with a notch 51f.

Each of the concave grooves 51a is disposed closer to the opening / closing body closing direction than the through-hole 51b for allowing the movable seat plate sensor 53 to face the opening / closing body 10, and has a long shape extending in the opening / closing body opening / closing direction of the slide body 51. Is formed.
An abutting surface 51a1 for abutting the convex portion 12a1 is formed at an end of the concave groove 51a on the opening / closing body closing direction side so as to be substantially orthogonal to the sliding direction of the slide body 51.
The contact surface 51a1 is arranged so as to have a gap h in the opening / closing body opening / closing direction with the convex portion 12a1 on the opening / closing body 10 side when the opening / closing body 10 is in a substantially fully closed state (FIG. 4). reference).
More specifically, in a state where the opening / closing body 10 is substantially fully closed and the movable seat 13 is moved in the opening / closing body opening direction relative to the opening / closing body main body 11 by the contact with the contact target portion p, A gap h is formed between the contact surface 51a1 of the slide body 51 and the convex portion 12a1 on the opening / closing body 10 side so that the slide body 51 can be slightly slid up and down.
The gap h is appropriately set so that the slide body 51 when a sliding failure occurs is slid in the closing direction of the opening / closing body by the impact when the opening / closing body 10 is fully closed.

  Each guide engaging portion 51e is a concave portion for engaging with a substantially convex rail portion (not shown) in the guide rail 20, and is formed continuously over the entire length of the slide body 51 in the opening / closing body opening / closing direction. ing.

The notch 51f is substantially U-shaped with the opening / closing body opening direction side open, and the width in the opening / closing body thickness direction is determined by the opening / closing body main body 11, the connecting member 12, the suspension bracket 12a, and the movable seat. The size is set such that the plate 13 can be inserted and the constricted portion of the retaining member 11b can be inserted.
The dimension of the notch 51f in the opening / closing body opening / closing direction is such that when the slide body 51 moves in the opening / closing body opening direction relative to the opening / closing body 10, the retaining member 11b is inserted in the opening / closing body closing direction. It is set so as to prevent the retaining member 11 b from coming into contact with the slide body 51.
Further, the dimension of the notch 51f in the opening / closing body opening / closing direction is such that the slide body 51 does not contact the retaining member 11b before the protrusion 12a1 on the opening / closing body 10 side contacts the contact surface 51a of the slide body 51. According to a preferred example of the present embodiment, the gap between the slide body 51 and the retaining member 11b is set to be equal to or greater than the gap h when the opening / closing body 10 is substantially fully closed.
According to the notch 51f, it is possible to prevent the end of the moved opening / closing body 10 from colliding with the slide body 51 when the opening / closing body 10 moves in the opening / closing body width direction due to the influence of wind pressure or the like. it can.
Furthermore, according to the notch 51f, in order to prevent interference between the slide body 51 and the retaining member 11b when slid in the opening / closing body opening direction, the retaining member 11b is disposed closer to the closing direction of the opening / closing body 10 to prevent The effect of preventing the member 11b from being removed, the crime prevention effect, and the like can be obtained effectively.

  Next, the members mounted on the slide body 51 will be described in detail. The discharge portion 52a and the capture portion 52b are non-contact detection sensors that non-contact sense obstacles closer to the closing direction than the opening / closing body 10. According to a preferred example of the present embodiment, a so-called photoelectric sensor is used. This photoelectric sensor captures an object sensing medium s such as infrared rays emitted from the emitting part 52a in the opening / closing body width direction by the capturing part 52, and detects the object. When the path s of the medium s is blocked by an object, a sensing signal is transmitted to the control unit 34.

The movable seat plate sensor 53 is a so-called proximity sensor that senses a metal object approaching and transmits a sensing signal thereof.
The movable seat plate detection sensor 53 is disposed inwardly of the opening / closing body opening direction side of the groove 51a on the outer surface of the slide body 51, and is opened / closed through a through hole 51b formed in the slide body 51. The swing piece 14 when swinging in the direction is sensed.
Therefore, according to the movable seat plate detection sensor 53, it is possible to indirectly detect that the opening / closing body 10 has come into contact with an obstacle on the closing direction side.

  The storage portion detection sensor 54 is a proximity sensor that is substantially the same as the movable seat plate detection sensor 53, on the outer surface of the slide body 51 opposite to the movable seat plate detection sensor 53, and on the inner surface of the guide rail 20. When the opening / closing body 10 is opened to the opening direction side slightly from the predetermined fully opened position so as not to approach (that is, not to misdetect the inner side surface), The sensed part 31b is sensed.

  In a preferred example of the present embodiment, for example, when the movable seat plate 13 is inclined with respect to the opening / closing body width direction (substantially horizontal direction in the illustrated example) during the closing operation of the opening / closing body 10, In order to be able to recognize the abnormality when there is an abnormality such as when only the slide body 51 no longer protrudes, both the left and right sensor units 50a and 50b have the movable seat plate detection sensor 53 and the storage part, respectively. Although the detection sensor 54 is provided, the movable seat plate detection sensor 53 and / or the storage unit detection sensor 54 of either one of the sensor units 50a (50b) may be omitted.

The opening / closing device A configured as described above is controlled to detect that the opening / closing body 10 during the opening operation has reached a predetermined fully-open position by a fully-open sensing means (not shown) and to stop the opening operation of the opening / closing body 10. The
The fully open sensing means includes a limit switch that operates in accordance with the amount of rotation of the drive source 33, the take-up shaft 32, and the like in the storage unit 30, and an encoder that detects the amount of rotation of the drive source 33, the take-up shaft 32, etc. By using a load sensing device that senses the load of the drive source 33 when the movable seat plate 13 comes into contact with the storage unit 30, the opening / closing body 10 is sensed to be in the fully open position, and the sensing signal The drive source 33 may be configured to stop according to the above.
Further, the opening / closing device A is opened / closed by a detection signal from the storage unit detection sensor 54 when the opening / closing body 10 during the opening operation does not stop at a predetermined fully open position due to a failure of the full opening detection means. The body 10 is controlled to stop the opening operation.

Thus, according to the opening / closing device A, even if the full-opening stop means fails, the end portion in the closing direction of the opening / closing body 10 (specifically, the movable seat plate 13) is stored in the storage portion 30. It is possible to prevent the inner wall of the movable seat 13 from colliding with the storage unit 30 or the like.
In addition, since the storage unit detection sensor 54 for detecting the end of the opening / closing body 10 in the closing direction is not provided in the storage unit 30, the storage unit 30 can be downsized or the space on the storage unit 30 side can be changed. It is possible to use the space more effectively by installing the members and equipment.

  In addition, according to the present embodiment, the sensor unit 50a (or 50b) that slides in the opening / closing body opening / closing direction together with the opening / closing body 10 is supported by the guide rail 20, so that the wind pressure, vibration during the opening / closing operation, etc. Even when the opening / closing body 10 is bent in the thickness direction by the sensor unit 50a (50b), the sensor unit 50a (50b) is inclined in the opening / closing body thickness direction, so that the movable seat plate detection sensor 53, the storage unit detection sensor 54, the discharge unit 52a. In addition, it is possible to prevent the capturing unit 52b from causing poor detection.

Furthermore, as another function and effect of the above-described opening / closing device A, in the unlikely event that the sensor units 50a and 50b are slid due to freezing, foreign object biting, or the like, the opening / closing body 10 may be closed. 4B, the convex portion 12a1 on the opening / closing body 10 side contacts the contact surface 51a1 on the sensor unit 50a (or 50b) side, and the sensor unit 50a (or 50b) moves in the opening / closing body closing direction. It is forced to move.
When the opening / closing body 10 is substantially fully closed, the movable seat plate 13 moves in the opening / closing body opening direction relative to the opening / closing body 10 by the contact with the contact target portion p, and the movable seat plate is moved by the movement. 13 abuts on the connecting member 12.
For this reason, the sensor unit 50a (or 50b) is forcibly pushed in the closing direction of the opening / closing body while foreign matter or the like is still caught between the sensor unit 50a (or 50b) and the guide rail 20. Even in this case, the sensor unit 50a (or 50b) causes the gap h between the contact surface 51a1 and the convex portion 12a1 to be opened and closed by the impact when the movable seat 13 contacts the connection member 12 as described above. Move in the closing direction.
In addition, the foreign matter or the like is caused by vibration, friction, or the like when the sensor unit 50a (or 50b) is forcibly pushed in the closing direction or when the movable seat plate 13 comes into contact with the contact target portion p. May come off.
Therefore, the normal sliding operation of the sensor unit 50a and / or the sensor unit 50b can be restored, and as a result, the sensing function of these sensor units 50a and 50b can be favorably maintained.

  In addition, according to the said embodiment, although the accommodating part detection sensor 54 was arrange | positioned in the closing direction edge part of the opening / closing body 10 via the sensor unit 50a (or 50b), the accommodating part detection sensor 54 is provided. It is also possible to adopt a structure in which the opening / closing body 10 is directly fixed to the end in the closing direction (specifically, the movable seat plate 13 or the like).

  Further, according to the embodiment, the opening / closing body 10 during the opening operation is sensed by the full-opening sensing means other than the storage unit detection sensor 54 when the opening / closing body 10 during the opening operation has reached the predetermined fully opened position. However, the storage unit detecting sensor 54 detects that the opening has exceeded the predetermined fully open position, but the full opening detection means is omitted and the opening / closing body 10 during the opening operation has reached the predetermined fully open position. It is also possible to adopt a structure in which the storage unit detection sensor 54 detects the above.

  Further, according to the above embodiment, the opening / closing body 10 during the opening operation is positioned closer to the opening direction than the predetermined fully opened position by disposing the storage unit detection sensor 54 on the end side in the closing direction of the opening / closing body 10. Although the position detection sensor 54 is arranged at a predetermined position in the opening / closing direction of the opening / closing body 10, the opening / closing body 10 during the opening operation or the closing operation is in a predetermined position. It is also possible to have a structure that senses this.
