FIG. 7 is a schematic perspective view showing another embodiment of the opening / closing device of the present invention, FIG. 8 is a schematic perspective view showing another embodiment of the opening / closing device of the present invention, and FIG. 9 is a drive unit in FIG. FIG. 3 is a partial cross-sectional view showing one example.

1 and 2, reference numeral 1 is a switchgear,
It is composed of an opening 3, a holding portion (sash) 4, an opening / closing body 5, and a drive device 6.

The regulator section 11 is a known one.
That is, the pull control cable 13 is routed in a loop shape via the drive unit 7, and the carrier plate 14 is fixed to a part thereof. And carrier plate 14
Is fixed to the opening / closing body 5 and can be moved up and down (in the direction of arrow AB) by being guided by a guide rail 12 mounted inside the door 2.

It is also possible to attach the sash 4 and the regulator portion 11 in the left-right direction of the door 2 and open / close the opening / closing body 5 in the left-right direction of the door 2.

The opening / closing body 5 is composed of a door plate 5a made of the same material as the door 2, a glass plate 5b and / or a net plate 5c, and a regulator section 11 and a driving section 7 respectively.
Are provided. It should be noted that the regulator unit 11 and the drive unit 7 may be appropriately arranged in order to prevent the door width from being increased.
Further, it is also possible to open and close the opening / closing body of the door plate 5a, the glass plate 5b and / or the mesh plate 5c in the up / down direction or the left / right direction by one drive unit 7.

When the operator operates the lever 21 of the opening / closing body switch 10 after selecting the button 25a, 25b or 25c of the changeover switch 9 shown in FIG. 4, the opening / closing body 5 (5
a, 5b or 5c) is a pull control cable 13
Is driven to move the carrier plate 14 along the guide rail 12 to open and close the opening / closing body 5.
34 is a power supply.

The details of the drive unit 7 are shown in FIG. That is, a cable drum 16 for winding up and feeding out an inner cable (not shown) of the pulling control cable 13 is connected to the output shaft end of the electric motor 15 which is a driving force source.

A plate 18 made of a disk-shaped magnetic material (for example, iron) having a plurality of slits 17 in the circumferential direction is fixed to the upper end surface of the cable drum 16. The cable drum 16 and the plate 18 are housed in the drive unit 7, and then a housing cap 19 is mounted. A proximity switch 20 is attached to the housing cap 19 so as to correspond to the slit 17. With this proximity switch 20, the number of slits 17 that pass with the rotation of the plate 18 can be measured and the amount of rotation of the cable drum 16 can be detected. As a result, the winding amount of the inner cable of the control cable 13, that is, the moving amount of the opening / closing body can be detected.

The changeover switch 9 is shown in FIG. The changeover switch 9 includes a door plate 5a which is an opening / closing body,
Buttons 25a corresponding to the glass plate 5b and the mesh plate 5c,
25b and 25c are formed on the switch body 24 so that the opening / closing body can be switched. Then, the switching signals of the buttons 25a, 25b and 25c are sent to the control box 8. Control box 8
Then, it is possible to select the electric motor 15 of the drive unit 7 by detecting the switching signal from the changeover switch 9.

FIG. 5 shows the opening / closing switch 10. The open / close switch 10 is a slide type lever 2
1 is continuously slid along a guide groove 23 formed in the switch body 22. Then, a signal such as a voltage value at the position where the lever 21 is set is sent to the control box 8.

In the control box 8, the opening signal from the open / close switch 10 is detected to drive the electric motor 15 of the drive unit 7. Accordingly, the plate 18 is connected via the output shaft of the electric motor 15 and the cable drum 16.
When is rotated, the proximity switch 20 detects the rotational displacement of the plate 18 and feeds back the position signal to the control box 8. Then, the rotation direction and the stop position of the electric motor 15 of the drive unit 7 can be automatically determined by comparing the opening signal input in the initial stage with the position signal.

In this way, the open / close body 5 can be moved to the fully open / closed or designated stop position by the changeover switch 9 and the open / close switch 10. Note that the present invention is not particularly limited to an open / close switch that can be operated continuously, and for example, an open / close switch corresponding to a plurality of predetermined opening degrees, which is, so to speak, digitally operated. Good

In the present embodiment (Embodiment 1), the proximity switch 20 is used as the detecting means, but the present invention is not limited to this. For example, the slit 17 is used.
It is also possible to employ a photoelectric switch together with the plate 18 having, or other type of optical sensor or magnetic sensor, contact potentiometer, rotary encoder,
A resolver or the like can be used. In short, it may be anything that can be compactly stored in the drive unit.
