Description

[Detailed Description of the Invention] <Field of Application in Industry-1-> In the present invention, when the sliding door is slightly pulled, the rotating body rotates, which is detected by the magnetically sensitive switch mechanism, and the drive mechanism is actuated to open and close the sliding door. It is related to I Jl switchgear.

<Prior Art> As is well known, there are various types of automatic sliding door opening/closing devices that use drive mechanisms to open and close sliding doors.

For example, a cloak with a built-in foot switch is placed in front of a sliding door, and when a person steps on the mat, the foot switch detects it and activates a drive mechanism, which opens and closes the sliding door. There are structures in which a sensor is installed near the sliding door, and when a person approaches the sliding door, the sensor detects and activates a drive mechanism to open and close the sliding door.

<Problems to be solved by the invention> However, the automatic opening/closing device for sliding doors of the conventional structure described above,
The sliding door opens and closes just by passing by the door. Therefore, for example, if a hallway and a room in a building are separated by a sliding door marked -1-, the sliding door will be opened and closed unnecessarily just by a person passing through the hallway near the sliding door. In reception rooms of hospitals and treatment rooms of hospitals, unnecessary opening and closing of sliding doors causes a great nuisance.

Furthermore, in automatic sliding door opening/closing devices, detection mechanisms such as switches and sensors are most likely to fail, and if they fail, not only will it be difficult to open and close the sliding door, but a specialist repair company will have to be called.

<Step 1 to solve the problem> The present invention was proposed in view of the above, and includes a structure in which a sliding door is slidably suspended inside a superstructure member via a bracket mechanism on a sunken rail. The traction member fixed to the bipedal bracket mechanism is connected to the drive mechanism provided inside the cross member, and the drive mechanism operates to pull the inner member and slide the sliding door along the rail. In such a sliding door opening/closing device, the 1-2 drive mechanism rotates when the sliding door slides toward the opening side;
The sliding door has a rotating body that does not rotate when it slides to the closing side, and the rotating body has a plurality of permanent magnets arranged along the rotation direction, and 1- a magnetically sensitive switch provided inside the cross member; The present invention provides a sliding door opening/closing device in which the mechanism is 1: and 6fi is that the sliding door is controlled to open and close by sensing with a permanent magnet facing the rotating body.

<Example> Below, the present invention will be explained based on embodiments shown in the drawings.

The sliding door l used in the present invention is suspended by a bracket mechanism 3 provided on the upper stile 2 slidingly engaged with a rail 5 provided inside the L cross member 4.

The bracket mechanism 3 described in -1- is constructed by connecting left and right fixing plates 6.6 fixed to the upper frame 2 with a horizontal plate 7, and left and right +lj wheels 8.8 provided on the horizontal plate 7 rest on the rail 5. The sliding door l can slide laterally.

A drive mechanism 9 is provided at one end of the inner side of the horizontal member 4, and an idler pulley lO is provided at the other end, and the drive mechanism 9 and the idler pulley 1 are provided.
0 and 0, an endless hollow member 11 made of bell) W is passed between the hook and the inner member 11, and the inner member 11 is fixed to the bracket mechanism 3. Therefore, when the traction member 11 is moved by the operation of the drive mechanism 9, the sliding door 1 slides along the rail 5 and opens and closes.

As shown in FIG. 2, the drive mechanism 9 shown in FIG.

It has a reversible drive part 12, and the drive shaft 1 of the drive part 12
3 is provided with a drive pulley 14, and the traction member 11 marked m is hung on the drive pulley 14, so that the traction member 11 is moved by the drive pulley 14 by the operation of the drive unit 12, and the sliding door 1 is moved by the drive pulley 14.
slides open and close. A one-way rotation transmission mechanism 15 is provided at the lower portion of the drive shaft 13 extending from the drive pulley 14 in the r direction. This rotation transmission mechanism 15 is mounted on the inner surface of the vertical cylinder member 16 as shown in FIG. A large number of mountain-shaped vertical grooves 17 are formed in parallel, a small diameter cylindrical member 18 is accommodated in each vertical groove 17, and the drive shaft 13 is inserted into the vertical cylinder member 16. Therefore, as shown by the solid line arrow in FIG. 3, when the drive shaft 13 rotates so as to press the cylindrical member 18 into the narrow space of the vertical groove portion 17, the vertical cylinder member 16 rotates together with the drive shaft 13. However, as shown by the chain arrow in Fig. 3, the drive shaft 1
3 rotates the cylindrical member 18 so as to face a wide space, the cylindrical member 18 idles within the wide groove portion 17, so even if the drive shaft 13 rotates, the vertical cylindrical member 16 does not rotate.

The vertical cylinder member 16 of the rotation transmission mechanism 15 described above has a rotating body 19.
is provided, and the rotating body 19 is rotated only when the drive shaft 13 rotates in one direction. Therefore, the specific structure of the rotation transmission mechanism 15 described above is one example, and if the rotating body 19 rotates only when the drive shaft 13 rotates in one direction, a rotation transmission mechanism 15 with a different structure may be used. It's okay.

'' A plurality of permanent magnets 20 are arranged along the rotational direction of the rotating body 19 along the isoquant lines. According to the embodiment shown in the drawings, eight permanent magnets 20 are provided around the rotating body 19 and are embedded in the rotating body 19. and,
The plate/Henne material 21 with one end attached to the drive part 12 is the vertical tube material 1
6 to prevent the vertical tube member 16 from rotating multiple times or rotating idly, and a magnetically sensitive switch mechanism 22 provided at the tip of the leaf spring member 21 to face the rotating body 19; Rotating body 1
The rotation of the permanent magnet 20 by the magnetically sensitive switch mechanism 2
2 is sensed.

The magnetically sensitive sinch mechanism 22 consists of a reed switch, a proximity switch, etc., and generates a signal when the permanent magnet 20 approaches.

Drive mechanism 9 described above. A magnetically sensitive switch mechanism 22 and sliding doors 1 provided at both ends of the upper horizontal member 4, although not shown in the drawings.
The stop switch and the like are connected to an electrical control mechanism (not shown). This electrical control mechanism controls the operation of the drive mechanism 9 by a signal from the magnetically sensitive switch mechanism 22,
This controls the sliding movement of the sliding door l. Specifically, when the sliding door l is in the closed state, when a person manually moves the sliding door l slightly to the open side, the traction member 11 moves, and the drive pulley 14 rotates by the amount of movement of the traction member 11, so that the rotation transmission mechanism 15
The rotating body 19 rotates via the
approaches the magnetically sensitive switch mechanism 22 and generates a signal. Based on this signal, the electric control mechanism operates the drive mechanism 9, the drive shaft 13 rotates, the drive pulley 14 moves the traction member 11, and the sliding door 1 slides toward the opening side, and the rotation transmission mechanism 15 rotates the sliding door 1. The body 19 rotates as one. In this case, the rotating body 19 rotates and each permanent magnet 20
1 Even if signal 3 occurs due to the primary magnetically sensitive switch approaching mechanism 22, electric extenuating switch 1 controls signal 6 and does not change the operation of drive mechanism 9. .

In this way, the sliding door l slides to the open side, reaching the end of the upper cross member 4, and reaching the fully open state I! , the switch mechanism provided at the end of the upper crosspiece 4 detects this and supplies a signal to the electrical control mechanism, which stops the operation of the drive mechanism 9 and the 11 stages of internal ties. After several seconds have elapsed, the drive mechanism 9 is operated in reverse to rotate the drive shaft 13 in the opposite direction, thereby causing the traction material 11 to move backward and the sliding door 1 to slide toward the closing side.

When the drive shaft 13 rotates in the opposite direction, the rotating body 19 does not rotate due to the rotation transmission mechanism 15, so that the magnetically sensitive switch mechanism 22 is not sensed by the permanent magnet 20.

On the other hand, as described above, when the sliding door l is in the fully open state yE, the operation of the drive mechanism 9 is stopped, and one of the permanent magnets 20 approaches the magnetically sensitive switch mechanism 22 due to the rotation stop of the one-rotator 19 +L state. Also, the electric control mechanism operates electrically so as not to operate the drive mechanism 9 until a new signal from the magnetically sensitive switch mechanism 22 is supplied.

When the sliding door 1 slides to the closing side and reaches the end of the upper cross member 4 and becomes fully closed, a switch provided at the end of the upper cross member 4 generates a signal and supplies it to the electrical control mechanism. , the reverse operation of the drive mechanism 9 is stopped, so the sliding door 1 is stopped.

In addition to the above-mentioned Ja rule, the electric control mechanism can change the electric braking action to the drive mechanism 9 just before the sliding door 1 is fully opened or completely closed, so that the stopping state of the sliding door 1 is slowed down, or It is also possible to give a speed difference to the operating state of the drive mechanism 9 so that the sliding door 1 slides quickly only when it is opened or closed. Furthermore, if an object hits the sliding door 1 or a person stops the sliding door 1 while it is sliding toward the closing side, the drive mechanism 9 will stop operating, and if the sliding door 1 moves slightly toward the opening side, the permanent magnet 20 will stop. The drive mechanism 9 is actuated by acting on the magnetically sensitive switch mechanism 22, and the sliding door 1 is slid toward the open side.

The present invention has been described above with reference to the embodiments of the drawings.
The present invention is not limited to the embodiments described above, and the structure described in the claims may not be modified.
, you can easily implement it in any way you like.

<Effects of the Invention> In summary, according to the present invention, 161 houses were
■F) Just by moving to the open side, the drive mechanism is activated and the sliding door is slid to the open side, and when it reaches the full [1H shape fg, it is slid to the closed lL side, so 1" is close to 1 door. The sliding door will not open even after passing through I,%. (The sliding door does not open unnecessarily even if you apply force.) Since there is no need for a detector for the conventional 1114 and sensor etc., it is less likely to malfunction, and the 11F
This is a W6'z' type with practical value for use as an indoor partition.
