However, if the receiving antenna is attached to the wall surface near the shutter or the front surface of the storage box of the shutter curtain using the antenna attachment tool, the antenna and the cable connecting the antenna to the inside will be exposed, and it will be an eyesore. In some cases, the design of the device (switching device) was damaged. In addition, there is also the problem that it takes a lot of time and effort to search for a preferable installation location for mounting the antenna and to install the antenna. On the other hand, it is conceivable to store the receiving antenna in the storage box of the shutter curtain, but since the storage box is made of metal, it is difficult for the operation signal from the controller to reach it, and there is a problem that it can only be operated near the opening and closing device. rice field.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a structure of an opening/closing device which has a good appearance and can easily improve reception sensitivity.

Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The structure of the opening/closing device according to claim 1 of the present invention includes an opening/closing body 13 for opening/closing an opening 31 of a building 27,
an opening/closing device 15 that is provided near the opening 31 and electrically opens and closes the opening/closing body 13;
a control panel 17 provided in the vicinity of the opening 31 and conductively connected to the switch 15 for controlling the operation of the switch 15;
a receiving unit 19 that outputs a wireless operation signal from the controller 39 to the control unit 35 provided in the control panel 17;
a metal case 21 having an inspection opening 47 that covers at least the control panel 17 and exposes the control panel 17;
a cover 23 made of an electromagnetic wave permeable material detachably attached to the inspection port 47;
It is attached to the back surface 53 of the lid 23 and conductively connected to the receiver 19 via a cable 57 and a connector 59 provided at the end of the cable 57 to receive an operation signal from the controller 39 and receive the signal. a cover antenna 25 to be sent to the unit 19;
with
A built-in antenna 45 is connected in advance to the antenna circuit of the receiving unit 19,
When the connector 59 is conductively connected to the receiving section 19, the control section 35 disconnects the built-in antenna 45 and the receiving section 19 and connects the lid antenna 25 and the receiving section 19. characterized by

In this switchgear structure, at least the control panel 17 is covered with a metal case 21 . “At least the control panel 17 is covered” means that part or all of the switch 15 or the switch 13 may be covered together with the control panel 17 . An inspection opening 47 is formed in the case 21 . The inspection port 47 is covered with a detachably attached cover 23 made of an electromagnetic wave permeable material such as resin. Maintenance of the control panel 17 and the opening/closing device 15 is performed by accessing the exposed control panel 17 and the opening/closing device 15 by removing the cover 23 .
A lid antenna 25 is attached to the rear surface 53 of the lid 23 . A cable 57 is connected to the lid antenna 25, and a connector 59 is provided at the end of the cable 57. As shown in FIG. The connector 59 of the lid antenna 25 is coupled to the receiving section 19 of the control panel 17 and conductively connected to the control panel 17 . The lid 23 is made of an electromagnetic wave permeable material (made of resin) and can secure a relatively large area, so that the reception performance is improved compared to the conventional built-in antenna 45 provided covered with the metal case 21. be able to. This makes it possible to receive an operation signal from a remote location.
Further, since the cover antenna 25 is attached to the back surface 53 of the cover 23 , when the cover 23 is attached to the inspection opening 47 , the antenna is on the back side and does not appear on the exterior of the case 21 . As a result, unlike conventional optional antennas, the antenna is not exposed outside the case 21 or on the outer wall surface of the building 27, and the cable or the like connecting between the antenna and the case 21 is not exposed. Therefore, the design of the opening/closing device 11 is not spoiled.
Furthermore, the work can be completed simply by replacing the existing metal cover with the resin cover 23 and the cover antenna 25, and the installation location can be changed like a conventional optional antenna installed outside the case 21. There is no need to search for it or perform complicated installation work. Therefore, it is not necessary to search for an installation place, and the optional antenna can be installed very easily.
Further, in the structure of this opening/closing device, the cover antenna 25 is used as an optional antenna. Note that the structure of the opening/closing device does not exclude the configuration in which only the lid antenna 25 is connected to the receiving section 19 . That is, in the structure of the opening/closing device, only the lid antenna 25 may be attached to the receiving section 19 as the main antenna.
When the lid antenna 25 is provided as an optional antenna together with the built-in antenna 45 , the built-in antenna 45 is connected to the receiver 19 in advance. The built-in antenna 45 is mounted on the substrate of the control section 35, for example. Conventionally, the built-in antenna 45 can receive an operation signal from the controller 39 in the vicinity of the opening 31 even if the cover 23 is made of existing metal. For example, since the case 21 has a structurally necessary gap such as a gap, the signal is transmitted through such a gap. However, since the built-in antenna 45 is covered with the metal case 21 and the metal lid 23 from a place farther than the opening 31, electromagnetic waves are blocked, and sufficient operation signals can be received. becomes difficult.
The controller 35 can detect that the connector 59 of the lid antenna 25 is connected to the receiver 19 . When the connector 59 is coupled to the receiving section 19, the control section 35 cuts off the connection between the existing built-in antenna 45 and the receiving section 19, and connects the cover antenna 25 with improved receiving sensitivity to the receiving section 19. . The control unit 35 detects the connection of the connector 59 and switches between the built-in antenna 45 and the lid antenna 25 in terms of circuitry. In other words, when the cover antenna 25 is connected, the built-in antenna 45 is disabled. For example, when the lid 23 is detached and the connector 59 is disconnected during maintenance, the lid antenna 25 is removed, but in that case the built-in antenna 45 on the board can receive signals.

The structure of the switching device according to claim 2 of the present invention is the structure of the switching device according to claim 1,
A recess for mounting the lid antenna 25 is formed on the rear surface 53 of the lid 23 .

In this structure of the opening/closing device, a concave portion for mounting the lid antenna 25 is formed on the rear surface 53 of the lid 23 . The concave portion can be a clip 63 having a concave portion between a pair of claw portions, or a concave groove formed in the rear surface 53 at the same time when the lid body 23 is molded. The lid antenna 25 can be configured using an antenna wire 55 as an antenna, for example. The antenna wire 55 can be attached in an S-shape, for example, bent at a plurality of locations. In this case, the antenna wire 55 can be fixed at a predetermined position on the rear surface 53 by holding the front and rear portions of the bent portion 65 in the clip-shaped recess.

The structure of the switching device according to claim 3 of the present invention is the structure of the switching device according to claim 1 or 2,
The surface of the lid 23 is unified with the same design as the surface of the case 21 .

In the structure of this opening/closing device, the metal case 21 and the cover 23 made of an electromagnetic wave permeable material (made of resin) attached to the inspection opening 47 thereof have the same design. The "same design" includes, for example, coating of the same color, application of seamless and integral patterns, the same surface treatment, attachment of the same interior material, and the like.

According to the structure of the switchgear according to claim 1 of the present invention, an antenna attachment tool or the like is not required outside the case, the appearance is improved, and the reception sensitivity can be easily improved.
In addition, when the cover is removed during maintenance or the like, reception is possible with the built-in antenna, and when the cover is attached, reception is automatically switched to the cover antenna.

The shutter curtain 13 as an opening/closing member opens and closes by moving up and down an opening 31 provided in the wall 29 of the building 27 or the like. A pair of guide rails 33 are provided on both sides of the opening 31 in the frontage direction. The left and right side edges of the shutter curtain 13 are guided by the guide rails 33 to move up and down, thereby opening and closing the opening 31 .

In this embodiment, the shutter curtain 13 is a sheet curtain. Therefore, the shutter device 11 is a sheet shutter. The sheet curtain is made of a sheet material such as soft vinyl chloride resin having a thickness of 0.8 to 1 mm. In addition, sheet curtains are made of sheet materials made of other resins, rubber sheet materials, woven fabrics, resin net screens, metal net screens, silica cloth, glass cloth, etc. A material obtained by combining or laminating these materials may be used, and the material constituting the shutter curtain may be a material having fire resistance, fire resistance, and flame resistance.

The opening/closing device 15 is provided near the opening 31 and electrically opens and closes the shutter curtain 13 . In this embodiment, the opening/closing device 15 is composed of a tube motor, and opens and closes by winding up or rewinding the shutter curtain 13 . Therefore, the shutter device 11 does not have general mechanical parts such as sprockets and chains. The shutter device 11 is configured with a simple mechanism by using a tube motor as a drive source. Note that the mechanism of the opening/closing device 15 is not limited to this.

The control panel 17 is provided near the opening 31 . The control panel 17 is conductively connected to the switch 15 and controls the operation of the switch 15 . As shown in FIG. 4, the control panel 17 is provided with a control section 35, a driving section 37 which is a driving control section, a receiving section 19, and the like. Commercial power is supplied to the control panel 17 . The control panel 17 wirelessly receives an operation signal from a controller 39 (FIG. 4), which will be described later, and controls the operation of the switch 15 . That is, by operating the controller 39, the shutter device 11 can raise and lower the shutter curtain 13 and stop the shutter curtain 13 by wireless remote control.

The controller 39 is configured separately from the control panel 17, and is detachably held, for example, on the wall 29 near the opening 31 provided with the shutter device 11, or carried by the operator. The controller 39 includes a transmitter (not shown), an operation key 41, a storage battery, a dry battery, and the like, and is configured to output operation signals for opening, closing, and stopping the shutter curtain 13 . An operation signal output from the controller 39 is sent to the receiving section 19 of the control panel 17 as an electromagnetic wave.

The receiver 19 is provided on the control panel 17 . The receiving unit 19 outputs a wireless operation signal from the controller 39 to the control unit 35 provided in the control panel. The control board 17 includes a substrate 43 (FIG. 4). The substrate 43 is provided with the control section 35, the receiving section 19, the driving section 37, and the like. A circuit pattern for connecting these is formed on the substrate 43 by printed wiring or the like. The board 43 is housed inside a housing that covers the mounted components. Further, in this embodiment, the substrate 43 is mounted with a built-in antenna 45 (FIG. 4). The built-in antenna 45 is connected to the receiver 19 via an antenna circuit (not shown) that can be controlled by the controller 35 .

The case 21 is made of metal such as steel. The case 21 has an inspection opening 47 that covers at least the control panel 17 and exposes the control panel 17 . When the opening 31 is opened, the shutter curtain 13 is rolled into a cylindrical shape and placed horizontally near the upper edge (lintel) of the opening 31 . The case 21 is formed in a substantially rectangular parallelepiped shape and has a volume for accommodating the wound shutter curtain 13 . Further, the case 21 has an inspection opening 47 formed by cutting out a part of the front surface. Inside the case 21, the switch 15 and the control panel 17 are arranged. The inspection opening 47 is an opening through which at least the control panel 17 is exposed. In this embodiment, the switch 15 and the control panel 17 are both arranged on the right end side of the case 21 when viewed from the front. For this reason, the inspection opening 47 is also formed on the right end side of the case 21 .

FIG. 2 is a side view of the vicinity of the case in the shutter device 11 shown in FIG.
The cover 23 is made of an electromagnetic wave permeable material, such as resin. The cover 23 is detachably attached to the inspection port 47 . The lid body 23 is formed by bending along a portion of the outline of the cross-sectional shape (substantially hexagonal shape shown in FIG. 2) perpendicular to the extending direction of the case 21 . Specifically, it has a substantially V shape as shown in FIG. The lid body 23 is formed, for example, to have a width of about 700 mm and a length of about 200 mm.

FIG. 3 is an exploded perspective view of the cover antenna 25 shown in FIG. 2 as seen from the inside of the case.
The cover 23 is fixed to the case 21 with screws or the like, and is easily detachable to close the inspection opening 47 . Screw holes 49 for screwing and notches 51 are formed in the four corners of the cover 23 . A lid antenna 25 is attached to the lid 23 .

The lid antenna 25 is attached to the rear surface 53 of the lid 23 . The lid antenna 25 has a linear antenna wire 55 . A cable 57 is connected to one end of the antenna line 55 . Incidentally, the antenna wire 55 may be the same cable 57 for connection and the antenna wire 55 .

A connector 59 is attached to the end of the cable 57 . The connector 59 can be of the so-called jack type. When a coaxial cable is used, a two-pole coaxial cable connector can be used. A mating connector 61 that can be coupled with the connector 59 of the cover antenna 25 is attached to the housing of the control panel 17 . The mating connector 61 is conductively connected to the receiving section 19 . The cover antenna 25 is conductively connected to the receiving section 19 of the control panel 17 via this connector 59 . The lid antenna 25 receives an operation signal output from the controller 39 and sends it to the receiver 19 .

A recess for mounting the lid antenna 25 is formed on the rear surface 53 of the lid 23 . The concave portion may be a substantially C-shaped clip 63 having a concave portion between a pair of claw portions, or a concave groove formed in the back surface 53 at the same time when the lid body 23 is molded. The lid antenna 25 can be configured using an antenna wire 55 as an antenna, for example. The antenna wire 55 can be attached in an S-shape, for example, bent at a plurality of locations. In this embodiment, a plurality of clips 63 are provided on the rear surface 53 of the lid 23 along the route of the antenna wire 55 . The clip 63 fixes the antenna wire 55 at a predetermined position on the rear surface 53 by holding the front end of the antenna circuit and the front and back of the bent portion 65 with the concave portion. A cable 57 extends from the lid 23 to which the antenna wire 55 is fixed. This cable 57 is inserted into the case through the inspection opening 47, and the terminal connector 59 is coupled to the mating connector 61 provided in the housing.

In the structure of the opening/closing device, the metal case 21 and the resin cover 23 attached to the inspection opening 47 have the same design, so that the appearance is unified. The "same design" includes, for example, coating of the same color, application of seamless and integral patterns, the same surface treatment, attachment of the same interior material, and the like. However, designs using materials that block the reception of operation signals, that is, that shield electromagnetic waves, are excluded. For example, the same design may be a process of adhering the same resin-made exterior panel as the lid body 23 to the outer circumference of the case 21 .

FIG. 4 is a block diagram showing a configuration example of an electric circuit in the switchgear structure shown in FIG.
As for the structure of the opening/closing device, the internal antenna 45 is connected in advance to the antenna circuit of the receiving section 19 . When the connector 59 is conductively connected to the receiver 19 , the controller 35 disconnects the built-in antenna 45 and the receiver 19 and connects the cover antenna 25 and the receiver 19 . Conversely, control unit 35 connects internal antenna 45 and receiving unit 19 when connector 59 is disconnected from receiving unit 19 . That is, the control unit 35 can detect the coupling of the connector 59 by monitoring the reception sensitivity. Based on this connector detection signal, the control unit 35 can selectively connect either the built-in antenna 45 or the cover antenna 25 to the antenna circuit.

Next, the operation of the configuration described above will be described.
In the structure of the opening/closing device according to this embodiment, at least the control panel 17 is covered with the metal case 21 . An inspection opening 47 is formed in the case 21 . The inspection opening 47 is covered with a detachably attached resin lid 23 . Maintenance of the control panel 17 and the opening/closing device 15 is performed on the exposed control panel 17 and the opening/closing device 15 by removing the cover 23 .

A lid antenna 25 is attached to the rear surface 53 of the lid 23 . A cable 57 is connected to the lid antenna 25, and a connector 59 is provided at the end of the cable 57. As shown in FIG. The connector 59 may be of a so-called jack type. The connector 59 of the lid antenna 25 is coupled to the receiving section 19 of the control panel 17 and conductively connected to the control panel 17 . The cover 23 is made of a resin having high electromagnetic wave permeability and can secure a relatively large area, so that the reception performance can be improved as compared with the built-in antenna 45 provided covered with the conventional metal case 21.例文帳に追加can be done. As a result, it becomes possible to receive the operation signal from a place farther than the built-in antenna 45 .

Further, since the cover antenna 25 is attached to the back surface 53 of the cover 23 , when the cover 23 is attached to the inspection opening 47 , the antenna is on the back side and does not appear on the exterior of the case 21 . As a result, unlike conventional optional antennas, the antenna is not exposed outside the case 21 or the outer wall surface of the building 27, and the cable connecting the antenna and the case 21 is not exposed. Therefore, the design of the switchgear is not spoiled.

Furthermore, the work can be completed simply by replacing the existing metal cover with the resin cover 23 and the cover antenna 25, and the installation location can be changed like a conventional optional antenna installed outside the case 21. There is no need to search for it or perform complicated installation work. Therefore, it is not necessary to search for an installation place, and the optional antenna can be installed very easily.

In the opening/closing device structure, the signal transmission/reception distance is extended by connecting the cover antenna 25 as described above. In recent years, a shutter control system has also been developed in which control signals are exchanged between shutter devices to control the opening/closing operation and stoppage of a plurality of shutter devices 11 . The structure of the switchgear can also be applied to such a configuration. In this case, conventionally, it was necessary to approach each shutter device 11, but by adopting the structure of the opening and closing device, it is possible to remotely operate a large number of sheet shutters that serve as partitions in a large factory. Attachment of the antenna 25 facilitates this.

In addition, in the structure of this opening/closing device, a concave portion for mounting the lid antenna 25 is formed on the rear surface 53 of the lid 23 . The concave portion can be a clip 63 having a concave portion between a pair of claw portions, or a concave groove formed in the rear surface 53 at the same time when the lid body 23 is molded. The lid antenna 25 can be configured using an antenna wire 55 as an antenna, for example. The antenna wire 55 can be attached in an S-shape, for example, bent at a plurality of locations. In this case, the antenna wire 55 can be fixed at a predetermined position on the rear surface 53 by holding the front and rear portions of the bent portion 65 in the clip-shaped recess.

Further, in the recessed groove, the groove width opening is formed slightly smaller than the width of the depth of the groove, and the antenna wire 55 is fitted or embedded in the recessed groove so that the antenna wire 55 does not protrude from the back surface 53 and is positioned at a predetermined position. can be held. As a result, the lid antenna 25 can be easily attached to the predetermined position of the lid 23 .

In addition, in the structure of this opening/closing device, the metal case 21 and the resin cover 23 attached to the inspection opening 47 have the same design. As a result, the case 21 and the lid body 23 made of different materials can have the same appearance, and the design is not spoiled.

In addition, in the structure of this opening/closing device, the cover antenna 25 is used as an optional antenna. Note that the structure of the opening/closing device does not exclude the configuration in which only the lid antenna 25 is connected to the receiving section 19 . That is, in the structure of the opening/closing device, only the lid antenna 25 may be attached to the receiving section 19 as the main antenna.

When the lid antenna 25 is provided as an optional antenna together with the built-in antenna 45, the receiver 19 is provided with the built-in antenna 45 in advance. The built-in antenna 45 is mounted on the substrate of the control section 35, for example. The built-in antenna 45 can receive an operation signal from the controller 39 in the vicinity of the opening 31 even if the cover 23 is made of existing metal. However, it is difficult to receive a sufficient operation signal from a location farther away than the opening 31 because it is covered with the metal case 21 and lid 23 .

The control unit 35 can detect that the connector 59 of the cover antenna 25 is connected to the receiving unit 19 . When the connector 59 is coupled to the receiver 19 , the controller 35 cuts off the connection between the existing built-in antenna 45 and the receiver 19 and connects the cover antenna 25 and the receiver 19 . The control unit 35 detects the connection of the connector 59 and switches between the built-in antenna 45 and the lid antenna 25 in terms of circuitry. That is, when the cover antenna 25 is connected, the built-in antenna 45 is disabled. For example, when the lid 23 is removed and the connector 59 is disconnected during maintenance, etc., the lid antenna 25 is removed. As a result, when the cover 23 is removed during maintenance or the like, reception can be performed with the built-in antenna 45, and when the cover 23 is attached, reception can be automatically switched to the cover antenna 25. - 特許庁
