Description

[Detailed description of the invention] Industrial application field This invention is equipped with a sleeve door and an opening/closing door, and in normal times the opening/closing door slides open and close, and in an emergency, the opening/closing door and the sleeve door rotate to open. 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 section.

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 reed switch is provided slidably in the longitudinal direction in the continuous groove of the door frame, and is fixed with a screw on the side of the door frame of the sleeve door. A magnet is installed in the groove of the upper stile so that it can slide freely in the longitudinal direction, and is fixed with a screw on the side of the door stile, so that when the sleeve door rotates outside the door frame, the reed switch and magnet are separated.
By turning it off, it is possible to detect the rotation of the sleeve door.

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 installed 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 reed switch 30 and a magnet 31 are provided facing each other at a position away from the hinge 16 on the upper stile 11 of the door 2 and the sleeve door 6, that is, on the side of the door stile 14. A relay 33 is connected in series to the power supply circuit of the controller 32 of the unit 22, and its normally open contact 33a is connected in series to the controller 32. When the reed switch 30 is ON, the controller 32 is energized and the opening/closing door 5 is opened. The reed switch 30 opens and closes according to a predetermined sequence of operations, and the reed switch 30 turns OFF.
At this time, the controller 32 is not energized and the opening/closing door 5 is stopped.

The reed switch 30 and magnet 31 are installed as shown in FIG.

In other words, the cross section 2 has a width that allows the upper stile 7 and the upper stile 11 to be arranged side by side, and a groove 40 is formed in the longitudinal direction on one side of the lower horizontal plate 2a. 4
A reed switch 30 is slidably inserted into the reed switch 30, and screw holes 41 are formed at both ends of the reed switch 30, and screws 42 screwed into the screw holes 41 are brought into contact with the lower horizontal plate 2a. reed switch 30
It is mounted in a raised position and in contact with the flange 40a.

The upper stile 11 has a substantially H-shape with indoor/outside vertical plates 11a, 11b and a horizontal plate 11c, and a groove 43 is formed in the horizontal plate 11c, and the magnet 31 can be slid into the groove 43. At the same time, threaded rods 45 are screwed into threaded holes 44 formed at both ends of the magnet 31, and the magnet 31 is lifted up by abutting against the horizontal plate 11c, and is attached by abutting against the flange 43a.

In this way, the positions of the reed switch 30 and the magnet 31 can be adjusted by sliding them in the longitudinal direction.

Therefore, when the sleeve door 6 is fixed, the opening/closing door 5 slides along the blind 2 and opens the opening 4.
Approximately half of the can be opened and closed.

At this time, reed switch 30 and magnet 31
Since both are 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 magnet 31 separates from the reed switch 30 and the reed switch 30 is turned OFF, so that the control unit 32 is not energized and the sliding movement of the opening/closing door 5 is stopped, resulting in safety.

In addition, since the reed switch 30 and magnet 31 are provided on the side of the door frame 14, when the sleeve door 6 rotates slightly, the reed switch 30 and magnet 31 are separated and the opening/closing door 5 immediately stops. It's even safer.

In addition, in the above embodiment, a single-swinging door was described, but in the case of a double-swinging door, the reed switch 3
0 and magnet 31, respectively, and the pair of reed switches 30 may be connected in series with a relay 33 as shown in FIG.

Effects of the invention: When the sleeve door 6 rotates outside the door frame 1, the reed switch 30 and the magnet 31 separate and the reed switch 30 is turned off, so it is possible to detect that the sleeve door 6 has rotated. Therefore, the opening/closing door 5 cannot be slid open/closed and is safe.

In addition, the reed switch 30, which requires wiring, is provided in the open section 2, and the magnet 3, which does not require wiring, is installed in the open section 2.
1 is provided on the sleeve door 6, the wiring will not be pulled or twisted and disconnected when the sleeve door 6 rotates, making the wiring work easier and preventing dust from entering the reed switch 30. There is no possibility of malfunction due to adhesion of foreign substances.

In addition, the reed switch 30 and the magnet 31 are provided opposite to each other on the side of the door frame 14 of the sleeve door 6 in the open door 2 and the upper stile 11, so that the sleeve door 6 is centered around the hinge 16 outside the door frame 1. When the sleeve door 6 rotates slightly, the reed switch 30 and the magnet 31 separate and it can be immediately detected that the sleeve door 6 has rotated.

Furthermore, since the reed switch 30 and the magnet 31 are fixed by screwing together the screws 42 and 45 and coming into contact with the flanges 40a and 43a of the grooves 40 and 43, by loosening the screws 42 and 45, the grooves The mounting position can be easily changed by sliding along the grooves 40, 43 in the longitudinal direction, and even if there is a dimensional error in the installation adjustment of the sleeve door 6, the reed switch 30 and magnet 31 can be accurately positioned at the predetermined positions. It can be mounted, and its position can be easily adjusted by loosening and tightening the screws 42 and 45.
