Abstract

PROBLEM TO BE SOLVED: To provide an elevator door opening regulator for regulating the opening of a slow-moving open/close door during running of an elevator not to cause an emergent stop of the elevator through the actuation of a close confirmation switch even when the slow-moving open/close door of the elevator is moved in its opening direction carelessly or out of mischief. SOLUTION: When a decorative panel 16 on the surface of a slow-moving open/close door 12 is pushed in its opening direction while the elevator is running, a limit switch 34 detects the sliding motion of the decorative panel 16. Upon the detection, a voltage is applied to a motor 32 for driving the slow-moving open/close door 12 through a door circuit 30 to urge the slow-moving open/ close door 12 in its closing direction. The slow-moving open/close door 12 is thus regulated for its movement and the elevator is prevented from being stopped as in an emergence through the actuation of a close confirmation switch out of carelessness or mischief.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening operation restricting device for an elevator, and more particularly to an elevator door opening operation restricting device for restricting a door opening operation by urging a low speed opening / closing door during elevator operation.

[0002]

2. Description of the Related Art In a general elevator, a plurality of doors having different opening and closing speeds are interlocked with each other to perform a sliding operation to quickly open and close the door for a wide entrance / exit so that an elevator user can get on and off smoothly. .

For example, FIG. 16 is a schematic view showing the internal structure of a basket room 100 of a general elevator. An opening / closing door that opens in the right direction in FIG. 16 is arranged at the entrance / exit 102. The opening / closing door is composed of a low speed opening / closing door 106 provided on the side closer to the door storage section 104 and a high speed opening / closing door 108 provided on the far side. When the opening / closing door receives the door opening operation signal, the low speed opening / closing door 106 and the high speed opening / closing door 108 start moving at the same time, and after a predetermined time elapses, the high speed opening / closing door 108 overlaps the low speed opening / closing door 106 to perform the opening operation. When the door closing operation signal is obtained, this reverse operation is performed. As a result, it is possible to prevent the user from feeling uncomfortable because the opening / closing door operates too early or too late.

Further, in FIG. 16, a door closing operation confirmation switch 110 is arranged at the upper left end of the entrance 102. The closing operation confirmation switch 110 is the high speed opening / closing door 108.
Is a switch that is turned on only when is completely closed, and supplies a signal to the lifting drive control unit of the car room 100. The closing operation confirmation switch 110 stops the raising and lowering drive of the basket chamber 100 when the closing operation of the opening and closing door is incomplete, and safety measures for elevator operation are taken.

[0005]

However, as shown in FIG. 17, the high speed opening / closing door 108 and the low speed opening / closing door 106 are arranged in a staircase shape, and the two are connected so as to move in conjunction with each other. ing. That is, when one of the doors starts to move, the other door also moves.
As a general opening / closing mechanism for the opening / closing door, a worm gear mechanism is adopted so that the opening / closing door can be manually opened even in the event of a power failure, and the opening / closing door can be opened in an emergency.
Therefore, for example, the user 112 inadvertently or mischievously moves the end portion 106a of the low-speed opening / closing door 106 to a force F equal to or more than the stop holding force of the low-speed opening / closing door 106 while the elevator is operating.
If it is pushed in the direction of the arrow, the high speed opening / closing door 108 will start to open together with the low speed opening / closing door 106. Then, the closing operation confirmation switch 110 is turned off, and the lift drive control unit causes the basket chamber 100 to make an emergency stop. As a result, there are problems that a trapping failure occurs and smooth elevator operation is hindered.

The present invention has been made to solve the above problems, and when the low speed opening / closing door of the elevator is moved in the opening operation direction by carelessness or mischief, the closing operation confirmation switch is operated. It is an object of the present invention to provide a door opening operation restricting device for an elevator, which is capable of restricting the opening operation of a low-speed opening / closing door during elevator operation so that the elevator does not operate and the elevator does not come to an emergency stop.

[0007]

It is characterized by restricting the movement of the low speed opening / closing door.

According to this structure, the opening / closing drive motor for the low-speed opening / closing door restricts the movement of the low-speed opening / closing door only when the sliding of the decorative panel is detected. It is possible to reliably prevent the opening operation of the inside door.

In order to achieve the above object, a third aspect of the present invention is the elevator door opening operation regulating device according to the first aspect of the invention, wherein the regulating means engages a retractable lock member with the low speed opening / closing door. The movement of the low-speed opening / closing door is restricted by the lever.

According to this structure, since the lock member, which is a mechanical means, is engaged with a part of the low speed opening / closing door, it is possible to securely and firmly regulate the movement of the low speed opening / closing door, and to open the door during elevator operation. The operation can be reliably prevented.

In order to achieve the above object, a fourth invention is the elevator door opening operation restricting device of the third invention, wherein the lock member engages with a hanging member of the low speed opening / closing door and It is characterized by restricting movement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 1 to 3 are conceptual diagrams illustrating an elevator door opening operation restricting device (hereinafter, simply referred to as restricting device) of the first embodiment, and FIG. 1 is an explanatory view showing a top view and a block diagram of a drive system. 2 is a front view seen from the elevator hall side, and FIG. 3 is a side view. FIG.
As shown in, the high speed opening / closing door 10 and the low speed opening / closing door 12 are arranged so as to partially overlap each other when the door is closed. In this case, the car room is on the side where the low-speed opening / closing door 12 is arranged, and the moving direction during the door opening operation is the arrow A direction. Low speed door 12
Is a main body panel 14 that moves in conjunction with the high speed opening / closing door 10,
A decorative panel 16 is arranged so as to cover the basket panel side of the main body panel 14. As shown in FIG. 1, the decorative panel 16 has a substantially U-shaped cross section, and the main body panel 14 is hooked by a guide rail 18 (see FIG. 1 and FIG. 3) arranged on the main body panel 14. 14
The main body panel 14 is slidable in the opening / closing direction of the low speed opening / closing door 12.

Further, the main body panel 14 itself is suspended by a hanger 24 having rotatable rollers 22, 22a on a door rail 26 fixed to a basket chamber (not shown). When the roller 22 rolls on the door rail 26, the low speed opening / closing door 12 can be opened and closed. The low-speed opening / closing door 12 is the elevator control unit 2
The door circuit 30 operated under the control of 8 drives a motor 32 such as a three-phase AC motor in a predetermined direction to perform opening / closing operation.

A limit switch 34 is arranged inside the main body panel 14 as a detecting means for detecting the sliding of the decorative panel 16 with respect to the main body panel 14. The limit switch 34 is fixed to a mounting base 36. When the limit switch 34 is turned on, the signal is supplied to the control device 34a, and the door circuit 3
The motor 32 is controlled via 0. Normally, the door circuit 30
Based on the door open signal from the elevator control unit 28, the voltage supplied to the motor 32 is gradually increased as shown by the solid line M in FIG. 4, the door is closed at a predetermined speed, and then the voltage is gradually increased. To (decrease door closing speed),
The door closing operation ends. When it is confirmed by the closing operation confirmation switch 110 described in FIG. 16 that the door closing operation is completed, the operation of the car room is started. At this time, the ON signal of the limit switch 34 is transmitted to the door circuit 3 via the control device 34a.
When 0 is input, the voltage supplied to the motor 32 is increased for a predetermined time during the operation of the car as indicated by the broken line N, and the low speed opening / closing door 12 is driven in the direction opposite to the arrow A. That is, the low-speed opening / closing door 12 is closed with an urging force that overcomes the force of opening the low-speed opening / closing door 12.

On the other hand, a bar-shaped operator 3 for operating the limit switch 34 is provided on the inner side 16a of the decorative panel 16.
8 are erected. Therefore, the makeup panel 16 is indicated by the arrow A.
The limit switch 34 can be operated by sliding in the direction. A spring 40 is provided around the operating element 38. And the main body panel 1
The mounting base 36 of the limit switch 34 provided in FIG. 4 is provided with a receiving portion 36a for receiving the spring 40. Therefore, the decorative panel 16 is always urged by the spring 40 in the direction opposite to the arrow A. A stopper rubber 42 is arranged on the outer surface of the main body panel 14 and has a function of absorbing a collision sound and a shock caused by a collision with the main body panel 14 when the decorative panel 16 slides.

A sliding member 44 is fixed to the lower portion of the main body panel 14, and the main body panel 14 is guided along a guide groove 46a provided in the sill 46 of the car room to smoothly open and close the opening / closing door. I can do it.

Now, as shown in FIG. 5, the user 112 in the elevator car room inadvertently or mischievously pushes the decorative panel 16 of the low-speed opening / closing door 12 in the direction of arrow A (door opening operation direction). When F is pressed against the biasing force of the spring 40, the operator 38 causes the limit switch 3
4 is turned on, a voltage is supplied to the motor 32 (see FIG. 1), and the low speed opening / closing door 12 is biased in the direction opposite to the arrow A direction. At this time, it is desirable that the voltage supplied to the motor 32 be determined in consideration of the performance of the motor 32 to such an extent that the low speed opening / closing door 12 does not move due to human power.

As described above, the movement of the decorative panel 16 of the low speed opening / closing door 12 is detected, and the low speed opening / closing door 12 is detected.
When the low speed opening / closing door 12 is pushed in the opening direction by the carelessness or mischief of the user, the low speed opening / closing door 12 does not perform the opening operation. As a result, the high-speed opening / closing door 10 does not perform the opening operation, and the closing operation confirmation switch 110 is not turned off, so that the elevator does not come to an emergency stop. Further, it is possible to reliably prevent the door opening operation during the elevator operation at low cost without adding a special regulation mechanism.

When the elevator is equipped with the above-described door opening operation restricting device, it is desirable to separately provide restriction releasing means in case the opening operation of the door is required in an emergency.

FIG. 6 shows a means for improving the rigidity of the low speed opening / closing door 12 because the low speed opening / closing door 12 has a double structure of a main body panel 14 and a decorative panel 16. In FIG. 6, in order to prevent the decorative panel 16 from being lifted up, a second hook 48 for sandwiching the lower guide rail 18 of the main body panel 14 together with the hook 20 of the decorative panel 16 is arranged. The second hook 48 has a substantially L-shaped cross section like the hook 20, and is adapted to firmly engage the guide rail 18 together with the hook 20. A reinforcing member 50 is arranged on the main body panel 14. The reinforcing member 50 has such a thickness that it does not come in contact with the back surface of the decorative panel 16, prevents the sliding of the decorative panel 16, and does not deform when the decorative panel 16 is pushed from the front side. I am trying.

FIG. 7 shows an example in which the mounting position of the limit switch 34 is changed. In the example described above, the limit switch 34 is arranged on the side of the high speed opening / closing door 10, but in the example of FIG. 7, it is arranged on the side away from the high speed opening / closing door 10. By arranging in this position, the high speed opening / closing door 10 does not get in the way when the limit switch 34 is inspected and replaced, so that the work can be performed smoothly. In this case, the spring 40 is arranged on the side of the high speed opening / closing door 10 as in the example of FIG. 1, but the spring 40 presses the inner surface of the decorative panel 16 and the outer surface of the main body panel 14.

FIG. 8 shows an example in which a rubber plate switch 52 is used instead of the limit switch. In this case, the decorative panel 16 moves to the inner surface of the decorative panel 16 and the outer surface of the main body panel 14, and when pressed against the main body panel 14, the rubber member forming the switch main body is crushed and the internal contacts are conducted. A rubber plate switch 52 is arranged.
By using this rubber plate switch 52, the sliding detection of the decorative panel 16 can be obtained with a simple structure.

Embodiment 2. In the first embodiment described above, an example in which the opening operation of the low speed opening / closing door is restricted by using the motor for driving the low speed opening / closing door has been described.
Now, an example of restricting the opening operation using the lock pin will be described. The means for detecting the sliding movement of the decorative panel 16 of the low-speed opening / closing door 12 is the same as that in the first embodiment, and the description thereof is omitted.

As shown in FIG. 9, a lock pin 56 made of a metal that can move back and forth is arranged on the upper beam 54 of the basket chamber. The lock pin 56 is arranged at a position facing the hanger 24, and when the lock pin 56 is projected, as shown in FIG.
As shown in (b), it is arranged so as to contact the side surface of the hanger 24. This lock pin 56 is the electromagnetic coil 5
The forward / backward movement is performed with respect to the hanger 24 by 8. For example, when the ON signal of the limit switch 34 shown in FIG. 1 is input to the control device 34a, the control device 34a excites the electromagnetic coil and causes the lock pin 56 to project. Further, a spring 60 is arranged on the rear end surface of the electromagnetic coil 58 to constantly urge the lock pin 56 in the arrow B direction. Therefore, when the ON signal of the limit switch 34 is not input, or after the output of the ON signal is stopped and a predetermined time has elapsed, the lock pin 56 is retracted in the direction of the arrow B by the urging force of the spring 60. Note that FIG. 9 (b)
The position where the lock pin 56 projects is the position where the low-speed opening / closing door 12 has completely completed the closing operation, as shown in FIG.

Further, as shown in FIG. 10, the lock pin 56 can be brought into engagement with the engagement hole 24a formed in the hanger 24 to obtain the same effect as described above.

Further, in FIG. 11, the lock pin 56a and the electromagnetic coil 58 are arranged on the hanger 24, and the lock pin 56a
When a is projected, it comes into contact with the roller 22 rolling on the door rail 26 fixed to the basket chamber. By the abutment of the lock pin 56a, the rotation of the roller 22 is stopped and the movement of the low speed opening / closing door 12 during the elevator operation is restricted, and the same effect as the above example can be obtained. In this case as well, the rotation of the roller 22 may be stopped by inserting the lock pin 56a into a hole (not shown) formed in the roller 22. Note that FIG. 10 and FIG.
Also in the case of 1, the protruding position of the lock pin is the corresponding position when the low speed opening / closing door 12 is completely closed. In this way, the low-speed opening / closing door 12 is locked by the metal lock pin 56.
Since the movement of the hanger 24 that suspends the low speed opening / closing door 12 is directly regulated at the center of movement of the low speed opening / closing door 12, it is possible to reliably and firmly move the low speed opening / closing door 12 and to open the door during the elevator operation. Can be prevented.

FIG. 12 shows another arrangement example of the lock pin 56. The lock pin 56 and the electromagnetic coil 58 are housed in a housing portion 46b formed at the bottom of a guide groove 46a provided in the sill 46 which is the lower surface of the basket chamber. The lock pin 56 is arranged so as to contact the side surface of the sliding member 44 fixed to the lower portion of the main body panel 14 when protruding. Therefore, when the electromagnetic coil 58 is excited by the ON signal of the limit switch and the lock pin 56 projects, the main body panel 14 is restricted from moving in the arrow A direction (door opening operation direction). When there is no ON signal of the limit switch, the lock pin 56 is pulled back downward by the spring 60, as in the example of FIG.
It is stored inside the storage portion 46b. In this case as well, the protruding position of the lock piece is the corresponding position when the low speed opening / closing door 12 is completely closed.

As described above, the lock pin 56 and the electromagnetic coil 5 are provided in the lower portion of the low speed opening / closing door 12 which has a sufficient space.
Since 8 can be arranged, the mounting is easy, and the movement of the low-speed opening / closing door can be reliably and firmly prevented, and the door opening operation during the elevator operation can be reliably prevented.

Embodiment 3. In the example shown in FIG. 13, the block-shaped lock piece 62 is advanced and retracted by the electromagnetic coil 58 that operates in response to the ON signal of the limit switch 34 (see FIG. 1), and the movement of the low speed opening / closing door 12 during elevator operation is restricted. To do. Similar to the example shown in FIG. 12, the electromagnetic coil 58, the lock piece 62, and the spring 60 for pulling back the lock piece 62 are stored in the storage portion 46 a of the sill 46 of the basket chamber. The lock piece 62 has a substantially rectangular parallelepiped upper portion and a flat surface portion. The lock piece 62 is capable of contacting the lower surface of the sliding member 44 fixed to the lower portion of the main body panel 14 when protruding. Then, when the lock piece 62 is projected, the sliding member 44 is pushed upward. Although not shown, since the low speed opening / closing door 12 is guided by the guide member at a plurality of positions, the low speed opening / closing door 12 is urged by the guide member by being pushed up by the lock piece 62, and the low speed opening / closing door 12 is operated during the elevator operation. Movement can be restricted. A concave (convex) portion is provided on the upper surface of the lock piece 62, and the concave (convex) portion is formed on the sliding member 44.
The movement restriction force may be enhanced by providing a convex (concave) portion that can be engaged with the portion. Further, although FIG. 13 shows an example in which one lock piece is provided, it may be arranged on each sliding member 44. In this case as well, the protruding position of the lock piece is the corresponding position when the low speed opening / closing door 12 is completely closed.

FIG. 14 shows an example in which the lock piece is arranged on the door rail 26 which is fixed to the upper portion of the basket chamber and suspends the low speed opening / closing door. Similar to other examples, the door rail 26
In the storage portion 26a formed in the above, a retractable lock piece 64 having an upper surface of a substantially rectangular parallelepiped shape, an electromagnetic coil 58a, and a spring 66 are stored. In this example, the electromagnetic coil 58a is of a type that releases excitation by an ON signal of the limit switch 34 (see FIG. 1), and the spring 66 is of a type that constantly biases the lock piece 64 upward. Therefore, when the ON signal of the limit switch 34 is supplied, the lock piece 64 projects to the upper surface of the door rail 26 by the urging force of the spring 66, and the roller 22
Block the orbit of the door opening operation side. As a result, the movement of the low speed opening / closing door 12 during the elevator operation can be restricted. Also in this case, the protruding position of the lock piece 64 corresponds to the position where the low-speed opening / closing door 12 has completely completed the closing operation. Further, when the ON signal of the limit switch 34 is not supplied, or after the ON signal is cut off and a predetermined time has elapsed, the electromagnetic coil 58a is excited and the lock piece 64 is accommodated in the housing portion 2.
6a, so that the low speed opening / closing door 12 can move freely.

Embodiment 4. The example shown in FIG. 15 is an example in which the movement of the low speed opening / closing door 12 is restricted during operation of the elevator by gripping the sliding members 44 fixed to the lower portion of the main body panel 14 from both sides.

In the sill 46 of the basket room, the guide groove 46
The sliding member 4 is provided in the storage portions 46b provided on both side surfaces of a.
A retractable electromagnet 68 that contacts the side surface of the No. 4 and a spring 70 that pulls the electromagnet 68 into the storage portion 46b are stored. The electromagnet 68 has a flat surface portion with a width sufficient to contact the sliding member 44, and the limit switch 34
The sliding member 44 is excited by the ON signal (see FIG. 1).
Adsorb to. In the electromagnet 68 or a bracket (not shown) holding the electromagnet 68, the electromagnet 68 has the sliding member 44.
The sliding member 44 can be fixed at the time of suction by configuring that a part thereof is held in the storage portion 46b even when the slide member 44 is suctioned. As a result, the movement of the low speed opening / closing door 12 can be restricted when the elevator is operating. Also, based on the signal from the limit switch 34, the electromagnet 6
When the excitation of No. 8 is released, the electromagnet 68 is pulled back to the inside of the housing portion 46b by the pulling force of the spring 70, and the movement of the sliding member 44 is allowed.

As described above, since the electromagnet 68 as the gripping means and the sliding member 44 are flat surfaces having a certain degree of spread, the positional relationship between the electromagnet 68 and the sliding member 44 does not require precision, and the mounting and mounting The movement of the low-speed opening / closing door 12 that is hard to be affected by the positional deviation during use and can be reliably and firmly regulated, and the door opening operation during the elevator operation can be reliably prevented. Note that the electromagnet 68 is also used in this example.
The arrangement position of is a position corresponding to the position where the low speed opening / closing door 12 completely completes the closing operation.

The restricting means for the low speed opening / closing door during the elevator operation described in each of the above-described embodiments is an example, and any restricting means for detecting the sliding of the decorative panel of the low speed opening / closing door having the double structure and operating it may be used. For example, the same effect can be obtained by using the regulation means having another structure.

[0045]

As described above, according to the present invention,
Even when the low-speed opening / closing door is pushed and closed in the opening direction by an unintentional or mischievous operation while the elevator is operating, the restricting means restricts the movement of the main body panel constituting the low-speed opening / closing door,
It is possible to reliably prevent the door opening operation while the elevator is operating, and it is possible to prevent an emergency stop due to the door opening operation without causing the elevator to make an emergency stop by operating the closing operation confirmation switch.
