Description

  The present invention relates to an elevator door device.

  In a conventional elevator door device, a sliding door provided at each of the car and the entrance of the hall, a door driving device provided at the car for driving opening and closing of the car sliding door, and a sliding door of the car provided at the sliding door of the car. An engagement device that engages with an engagement body provided on the vehicle and opens and closes a car and a landing door in an interlocking manner, and the engagement device includes a vertical fixed blade fixed to the sliding door of the car; A movable blade pivotally attached via a link in parallel with the fixed blade on the door pocket side of the fixed blade of the cage sliding door, and the fixed blade and the movable blade that the cage is landed and the engaging device is open When the cage sliding door is opened with the engagement body provided on the landing door in between, the mechanism that combines the link, cam and spring is used to open the sliding door of the cage. It is known that the movable blade moves in parallel to the fixed blade side, closes, engages and engages the engagement body, and the sliding door of the landing is opened in conjunction with the sliding door of the car (for example, (See Patent Document 1 and FIG. 7).

  Further, conventionally, as a way to more accurately synchronize the opening operation of the car door and the landing door when the car is landed, the car is interposed between a pair of engaging rollers (engaged members) provided on the landing door. A roller engaging portion is formed integrally with the engaging member when the front end portion of the engaging member provided on the door rotates and engages so that the car door and the landing door are opened and closed. Then, a pressure roller is inserted into the roller engaging portion, the rotation shaft of the pressure roller is implanted in the bracket, the bracket is rotatably supported on the door hanger, and a pin is projected from the bracket. A drive door for door opening / closing drive is fixed to this pin via a belt fixing device, so that the car door is attached to the drive belt not directly but via an engaging device, and the car door side engaging member Is fully engaged with the engaged member on the landing door side Until that is known that to avoid door open (for example, see Patent Document 2).

Conventionally, a pair of parallel doors that are arranged together with a link in the car door is intended to make the car door and the landing door work together so that the opening and closing operations of the car door and the landing door are perfectly matched. Blades, four rollers disposed on the left and right sides of the pair of blades when the car is landed, and an actuator for moving the pair of blades up and down. When the actuator pushes up one of the blades, the parallelogram is reduced, and the pair of blades are separated from the four rollers and become unlinked. When the actuator lowers the blade, the pair of blades is moved by the spring force. There is known one that spreads in the right and left and presses the rollers on both sides to interlock the landing door with the car door (for example, see Patent Document 3).
Patent Document 4 discloses an elevator control apparatus that employs a so-called landing open, which is a method of opening a car door in advance before the car is landed.

However, in the conventional elevator door device disclosed in Patent Document 1, the stationary blade relatively positioned on the door side is fixed to the car door and does not move, so the car door starts the door opening / closing operation. After that, the door is brought into contact with the engaging body of the landing door in accordance with the door opening / closing operation, and the car door and the landing door are engaged to open / close the interlocking door.
For this reason, unless the door opening / closing operation before the engagement between the car door and the landing door is made as low as possible, there is a problem that noise and vibration are generated due to a collision between the car side engaging device and the landing side engaging means. is there.

If the operation at the start of the door opening is slow, there is a problem that more time is required for opening and closing the door, and there is a problem that the door opening and closing operation is not smooth and looks worse.
In order to alleviate the above problems as much as possible, if the gap between the car-side engaging device and the landing-side engaging means is made as small as possible, the installation adjustment work will be complicated. There is a problem that work efficiency deteriorates.

In the conventional elevator door device disclosed in Patent Document 2, the structure of the engagement device is complicated, and the operation of the left and right car doors is symmetric when the door is opened in the center. It is necessary to provide a separate mechanism for this purpose, and there is a problem that the entire apparatus becomes large. (Note that examples of mechanisms for making the left and right car doors symmetrical in this case include a method of interlocking two car doors with a circulation rope, and a car door on the side where there is no car side engagement device. (A method of adding a mechanism similar to the car-side engagement device in order to shift the timing of the start of the belt operation and the start of the car door may be considered.)
In addition, it is necessary to have a design that can withstand the inertial force when the door is turned over, and this may also increase the size of the entire apparatus.

A conventional elevator door device disclosed in Patent Document 3 has a structure in which a car-side engaging device is a parallelogram-shaped link mechanism, and the landing-side engaging means is pressed from the inside when the car door and the landing door are engaged. It is. Therefore, it is necessary to provide engaging elements (rollers) on the landing side engaging means on both sides including not only one side of the car side engaging device but also the other side.
For this reason, it is necessary to provide as many landing-side engaging means as the number of floors required for each floor, and there is a problem that production costs are increased, and the area occupied by the landing-side engaging means in plan view is large. Therefore, there is a problem that avoiding this landing side engaging means, it is disadvantageous when an additional sill is installed on each of the car side and the landing side to reduce the sill interval.

  In an elevator adopting a conventional landing open as shown in Patent Document 4, the time required for opening and closing the door can be shortened, but the car is completely when the passenger in the car is looking downward. There is a problem that there is a possibility of giving anxiety to opening the door without stopping. In addition, in order to avoid noise and vibration due to the collision between the engagement devices, the operation immediately after the start of the door opening and closing must be made as low as possible, and the problem that the door opening and closing operation is not smooth and looks worse is patented. This is the same as that described in Document 1.

  The present invention has been made to solve such a problem, and the landing-side engagement means is relatively small and has a simple structure, and is made at a normal speed (not low speed) immediately after landing. ) To obtain an elevator door device that can prevent noise and vibration even when the door is opened, and can achieve smooth door opening and reduce the time required for opening and closing the door. Is.

A door pocket side stopper 22 is provided at a position in contact with the blade 9 side, and the door bag side blade 10 is further moved from the state closest to the door holding side blade 9 by the door pocket side stopper 22 to the first link 12 and the second link. The second link 13 is rotated to prevent the door pocket blade 10 from being separated from the door stop blade 9.

  The door side of the door side blade 9 is on the door side, and the door side blade 10 is located closest to the door side blade 9 and the landing side engaging means between the door side blade 9 and the door side blade 10 is located on the door side. A door stop side stopper 23 that restricts the door stop side blade 9 from moving beyond the predetermined position to the door stop side is provided so that 16 can be gripped sufficiently.

FIG. 4 shows a detailed configuration of the solenoid actuator 14.
The cylinder body is provided with a coil 14b formed by winding a conductive wire along the outer peripheral inner wall, and a through hole is formed in the center of the coil 14b on one side of the cylinder body. A fixed iron core 14c is attached.
A movable iron core 14d provided with a push bar 14a on one side is provided so as to pass the push bar 14a through the fixed iron core 14c.

  When the solenoid actuator 14 configured in this manner is in a state where a predetermined voltage is not applied to the coil 14b, the push bar 14a (movable iron core 14d) can freely protrude and retract (see FIG. a)) When a predetermined voltage is applied to the coil 14b, the movable iron core 14d is attracted to the fixed iron core 14c by electromagnetic force, and the push bar 14a is held in a protruding state (FIG. 7B). It is a solenoid.

In the elevator door device configured as described above, the car 1 travels and stops at a predetermined door zone (the car side engaging means 8 and the landing side in the vicinity of the floor where the car 1 stops). When entering the predetermined range in which the engagement means 16 can be engaged (for example, a range within about ± 200 mm of the landing position), the landing-side engagement means 16 of the landing door is the door stop of the car-side engagement means 8. It arrange | positions in the state which is not contacting between the side blade 9 and the door pocket side blade 10 (FIG. 1).
At this time, the door side blade 9 is arranged on the door side as viewed from the landing side engaging means 16, and the door bag side blade 10 is arranged on the side opposite to the door side blade 9 of the landing side engaging means 16.

When it is detected that the car 1 has entered the door zone, the solenoid actuator 14 is applied with voltage until the car 1 reaches the floor, and the door blade 9 is moved to the door pocket side. Move to.
Then, the door side blade 9 contacts and rotates the landing side engaging means 16, and the locking of the landing door by the locking member 16a is unlocked (FIG. 2).

Here, the operating force of the solenoid actuator 14 is sufficient as long as the landing-side engaging means 16 can be rotated to unlock the locking member 16a, and the landing door is opened. Strength is not required.
The moving speed of the door side blade 9 is reduced by the action of the damper 15 provided in the car side engaging means 8 so that the collision sound with the landing side engaging means 16 becomes sufficiently small.

Further, once the solenoid actuator 14 is actuated to move the door side blade 9 to the door pocket side, it is not necessary to actuate the solenoid actuator 14 for opening and closing the door on the floor, so that the solenoid actuator 14 is continuously operated. There is no worry of fever.
Further, even if the solenoid actuator 14 is operated outside the door zone due to a malfunction of the control system or the like, the door side blade 9 and the landing side engaging means 16 are engaged outside the door zone. There is no risk that the landing door will be unlocked.

In this way, when the car 1 starts to enter the door zone, the door lock side blade 9 is moved to the door pocket side by the solenoid actuator 14 before landing, and the landing door is unlocked, and the door lock side blade Since 9 is moved to the door pocket side, the landing side engaging means 16 is held by the door stopper blade 9 and the door pocket blade 10 (FIG. 2).
The solenoid actuator 14 allows the door side blade 9 to be opened on the door side without opening the car door and the landing door before the car 1 arrives after the car 1 enters the predetermined door zone of the stop floor. A door-side blade driving means is configured to move in a direction close to the blade 10 and come into contact with the landing-side engaging means 16.

That is, before landing, the car-side engaging means 8 and the landing-side engaging means 16 have already been engaged, so that after landing, the driving-side car door 3 (and the driven-side car door). 4) When the door starts to open, the landing door also starts to open at the same time.
At this time, the door side blade 9 and door pocket side blade 10 of the car side engaging means 8 and the landing side engaging means 16 are already in contact with each other, so that no collision noise or vibration is generated when the door is opened. The door opening operation can be accelerated immediately after the opening operation starts.

After the door opening operation is started, the door side blade 9 is pushed toward the door side relatively to the driving side car door 3 by the running resistance of the landing door to which no voltage is applied to the solenoid actuator 14, and the solenoid The push bar 14a of the actuator 14 also moves to the retracted position.
In this case, the moving speed of the door-holding blade 9 is sufficiently reduced by the action of the damper 15 provided in the car-side engaging means 8 described above.

After the door opening operation starts, when the driving side car door 3 (and the driven side car door 4) moves to the door bag side, the roller 19 rolls down the rolling surface of the cam member 21 and the lever 18 rotates. The first link 12 is also rotated in the same direction as the lever 18 via the connecting rod 20, and the door pocket blade 10 is moved to the door lock blade 9 while being parallel to the door lock blade 9. Move in the close direction.
The door side blade 9 and the door pocket side blade 10 grip the landing side engaging means 16 between them.

At this time, the door side blade 9 is restricted from moving from the predetermined position to the door side by the door side stopper 23, and the door side is such that the landing side engaging means 16 cannot be gripped during the door opening operation. The door side blade 9 is held at a position where the landing side engaging means 16 can be gripped so that the distance between the blade 9 and the door side blade 10 does not widen.
Thus, during the door opening operation, the landing side engaging means 16 is held by the door side blade 9 and the door pocket side blade 10 and engaged with the car side engaging means 8, and the car door and the landing door are maintained. Are linked together and opened.

On the other hand, when the driving side car door 3, the driven side car door 4 and the landing door are closed, the landing side engaging means 16 is held by the door side blade 9 and the door bag side blade 10, and the car side engaging means 8 and The doors are engaged, and the doors are interlocked and closed together.
In the vicinity of the fully closed state, the roller 19 of the door blade side blade driving means 17 comes into contact with the cam member 21, and the roller 19 now rolls upward on the rolling surface of the cam member 21. Then, the lever 18 rotates counterclockwise in FIGS. 1 to 3, the connecting rod 20 moves downward, and the first link 12 rotates in the same direction as the lever 18.

The door pocket side blade 10 moves in a direction away from the door stop side blade 9, and when the door is fully closed, the door pocket side blade 10 and the landing side engagement means 16 are separated to allow the car 1 to travel. It will be in the state where the distance of the extent which does not have trouble is opened.
The door side blade 9 is returned and held in the same position and in the same state as before the solenoid actuator 14 is activated, that is, before the car 1 enters the door zone, in a series of door opening and closing operations. The door side blade 9 is also separated from the landing side engaging means 16 and is in a state where a distance that does not hinder the traveling of the car 1 is provided.

  The elevator door device configured as described above has a car door provided in the car and provided with car-side engaging means, and a landing door provided in the landing and provided with landing-side engaging means. An elevator door device in which the car-side engaging means and the landing-side engaging means are engaged with each other, and the car door and the landing door are integrally opened and closed, provided in the car-side engaging means, A door side blade disposed on the door side of the landing side engaging means when the car is landing, and a door side provided on the car side engaging means substantially parallel to the door side blade, and the landing side when the car is landing The door is disposed on the side opposite the door to the side of the engagement means, and the door side blade for holding the landing side engagement means with the door side blade and the car after entering the predetermined door zone of the stop floor, Without opening the car door and landing door before landing, A door those side blade drive means for contact is moved in a direction close to the bag side blade platform side engagement means, but provided with.
