Description

[Detailed description of the invention] Industrial application field The present invention is equipped with a sleeve door and an opening/closing door, and the opening/closing door slides open and close in normal times, and the opening/closing door and the sleeve door rotate in an emergency. The present invention relates to a device for detecting the rotation of an opening/closing door and a sleeve door in a fully opening type door that can open the entire opening.

Prior Art As shown in Japanese Utility Model Application Publication No. 59-8481, a light emitter is provided on the sleeve door, and a light receiver facing the floodlight is provided on the vertical frame of the door frame or the other sleeve door, so that the door can be opened and closed. When the sleeve door is rotated, the opening/closing door blocks light from the optical path connecting the emitter and receiver, thereby detecting the rotation of the opening/closing door and the sleeve door. Detection devices are known.

Problems to be Solved by the Invention In such a rotation detection device, the emitter and receiver are open to the outside and face each other, so dust can adhere to the emitter and receiver, causing detection errors. In addition, since the rotating sleeve door is provided with a projector and a light receiver, it is necessary to prevent the electrical wiring from breaking when the sleeve door rotates, which makes electrical wiring troublesome.

Means and action for solving the problem A vertical shaft constituting a hinge that supports the sleeve door is rotatably supported, and a light transmission hole is formed at the end of the vertical shaft that protrudes inside the blind. A light beam type switch is created by installing a light emitter and a receiver inside the blind facing this light beam transmission hole to detect when the sleeve door has rotated outside the door frame, and the detection signal from this switch is used to open and close the door. The drive unit that slides the light is not energized, which prevents dust from adhering to the emitter and receiver and simplifies their electrical wiring.

Embodiment A door frame 1 includes a blind 2 and left and right vertical frames 3, 3,
An opening/closing door 5 and a sleeve door 6 are attached to the opening 4, and the opening/closing door 5 has a glass 10 mounted inside a frame assembly consisting of upper and lower frames 7, 8 and left and right vertical frames 9,
The arm door 6 has a glass 15 mounted inside a frame assembly consisting of upper and lower frames 11 and 12, a hanging frame 13, and a door frame 14, and the upper and lower sides of the hanging frame 13 are hinges 16.
The latch mechanism 18 is supported by the blind 2 and the base 18 so as to be rotatable in an out-of-plane direction, and a latch mechanism 18 is provided extending between the upper stile 11 and the blind 2.

A driving unit 22 consisting of a motor 20 and a driving pulley 21 and a driven pulley 23 are disposed in the blind 2, and a belt 24 is wound around both pulleys, and a moving body 25 is connected to the belt 24. This moving body 25 has rails 26 and rollers 2.
7, and is rotatably connected to one vertical stile 9 of the opening/closing door 5 by a hinge 28, and connected to the other vertical stile 9 via a latch mechanism 29.

The latch mechanisms 18 and 29 are always held, and can be freely rotated in an out-of-plane direction by operating an operating member (not shown).

A switch 30 that is turned on and off by the rotation of the hinge 16 is provided at a position adjacent to the hinge 16 in the door 2, and this switch 30 is turned on when the sleeve door 6 is within the door frame 1, and the switch 30 is turned on when the sleeve door 6 is in the door frame 1. When rotated outside frame 1, it turns OFF and the switch 3
0 is connected in series with a relay 33 to the power supply circuit of the controller 32 of the drive unit 22, and its normally open contact 33a is connected in series to the controller 32, and when the switch 30 is ON, the controller 3
When the switch 30 is OFF, the controller 32 is not energized and the door 5 opens and closes in a predetermined sequence.
is set to stop.

The switch 30 is installed as shown in FIGS. 4 and 5.

In other words, the blind 2 has a width that allows the upper stile 7 and the upper stile 11 of both doors to be arranged side by side in the out-of-plane direction, and a shaft bearing 40 is fixed to one side of the connecting horizontal plate 2a with a screw 41. A through hole 43 facing the support hole 42 is formed, and a vertical shaft 44 fixed to the connecting horizontal plate 11a of the upper stile 11 is fitted into the support hole 42 through the through hole 43 to form the hinge 16. However, a light transmitting horizontal hole 45 is formed in the protruding upper part of the vertical shaft 44, and
A light emitter 46 and a light receiver 47 are arranged on both sides of the vertical axis 44 facing the light transmitting horizontal hole 45 to constitute a switch 30, and when the sleeve door 6 is within the door frame 1, the light transmits through. When the hole 45 is directed toward the emitter 46 and the receiver 47, the light projected from the emitter 46 is received by the receiver 47 and the switch 30 is turned on, and when the sleeve door 6 rotates outside the door frame 1, the vertical shaft 44 rotates so that the light transmission hole 45 is oriented perpendicular to the emitter 46 and the receiver 47, and the light projected from the emitter 46 does not reach the receiver 47 and the switch 30 is turned off.
It becomes OFF.

Thus, when the sleeve door 6 is in the door frame 1, the opening/closing door 5 slides along the blind 2 and can open and close approximately half of the opening 4.

At this time, the light from the light emitter 46 reaches the light receiver 47 through the light transmission hole 45 and is received, so the switch 30
is turned on, the control unit 32 is energized and the opening/closing door 5 is opened/closed in the normal operation sequence.

Furthermore, when the latch mechanisms 18 and 29 are released by operating an operation member (not shown) and the opening/closing door 5 is pushed in an out-of-plane direction, the opening/closing door 5 and the sleeve door 6 are rotated in an out-of-plane direction, thereby opening the opening 4. Open the full width of.

At the same time, the vertical shaft 44 rotates so that the light from the emitter 46 does not reach the receiver 47 and cannot be received, and the switch 30 is turned off.
2 is not energized, the sliding movement of the opening/closing door 5 is stopped, and it is safe.

In the above embodiment, a single-swinging door is shown, but in the case of a double-swinging door, a pair of switches 30 may be provided on both sides, and the pair of switches 30 may be connected in series with a relay 33 as shown in FIG. .

Effect of the invention When the sleeve door 6 is inside the door frame 1, the floodlight 46
The light beam from the vertical axis 44 reaches the light receiver 47 through the light transmission hole 45, and the switch 30 does not detect it.
When the sleeve door 6 rotates outside the door frame 1, the vertical shaft 44 rotates, and the light beam from the floodlight 46 is blocked by the vertical shaft 44. It is safe because the opening/closing door 5 can be prevented from sliding by detecting the outward rotation.

In addition, the emitter 46 and the receiver 4, which require wiring,
7 is provided in the blind 2, and the vertical shaft 44 provided on the rotating sleeve door 6 protrudes into the blind 2 to form a light transmission hole 45, thereby forming the switch 30.
Even when the wire rotates, the wire will not be pulled or twisted and will not break, making wiring work easier.
In addition, a light emitter 46, a light receiver 47, and a light transmission hole 45
It is sufficient to prevent malfunctions due to dust adhering to the 2.
It can be easily installed in a small space inside, and since there is no member between the upper end of the hanging stile 13 of the sleeve door 6 and the lower surface of the blind 2, the gap between the two can be made small. The airtightness can be improved, and furthermore, since the light from the projector 46 is blocked when the vertical shaft 44 is slightly rotated, the detection operation can be performed immediately when the sleeve door 6 is slightly rotated outside the door frame 1, making it even safer.
