Embodiment 1 FIG.
1 is a front view of an elevator door engaging device according to Embodiment 1 of the present invention as seen from a landing side. In the figure, a base plate 2 is fixed to an upper portion of the car door 1. The base plate 2 is provided with a first engagement member (drive side engagement vane) 3 and a second engagement member (driven side engagement vane) 4. The longitudinal directions of the first and second engaging members 3 and 4 are parallel to the vertical direction.

  Further, the first and second engaging members 3, 4 are arranged at intervals in the opening / closing direction of the car door 1 (left-right direction in FIG. 1). The distance between the first and second engaging members 3 and 4 can be changed. When the car is moved into the door zone, the engaging roller 5 as a landing door side engaging portion provided on the landing door (not shown) is positioned between the first and second engaging members 3 and 4. To do. In this state, the distance between the first and second engaging members 3 and 4 is changed, whereby the first and second engaging members 3 and 4 are engaged with the engaging roller 5.

  In this example, the distance between the first and second engaging members 3, 4 is reduced, so that the first and second engaging members 3, 4 become engaged rollers 5 as shown in FIG. 2. Engagement, that is, the engagement roller 5 is clamped. As a result, the car door 1 and the landing door are moved together. Further, as the distance between the first and second engaging members 3 and 4 is increased, the engagement of the first and second engaging members 3 and 4 to the engaging roller 5 as shown in FIG. The match is released.

  On the upper part of the first engaging member 3, a coupling fitting 6 as a transmission body connecting portion is fixed. The upper end portion of the coupling fitting 6 is connected to a drive belt 7 as a power transmission body. The drive belt 7 is circulated by a drive motor (not shown) that is a drive source for opening and closing the car door 1. As a result, the connecting portion of the drive belt 7 to the coupling fitting 6 is moved in the opening / closing direction of the car door 1. That is, the operation of the drive belt 7 is transmitted to the car door 1 through the operations of the first and second engaging members 3 and 4.

  The first and second engaging members 3 and 4 are supported by the base plate 2 via the upper interlocking link mechanism 8 and the lower interlocking link mechanism 9. The interlocking link mechanisms 8 and 9 are attached to the base plate 2 with a space therebetween in the vertical direction.

  The interlocking link mechanisms 8 and 9 change the distance between the first and second engagement members 3 and 4 by displacing the first engagement member 3 and the second engagement member 4 in conjunction with each other. Let Further, the interlocking link mechanisms 8 and 9 displace the first engagement member 3 in parallel with the opening / closing direction of the car door 1 by the movement of the drive belt 7.

  The upper interlocking link mechanism 8 and the lower interlocking link mechanism 9 have the same structure. Each interlocking link mechanism 8, 9 has a floating support arm 10 and a rotation support arm 11. The floating support arm 10 has a first engaging member connecting portion 10a that is rotatably connected to the first engaging member 3. The rotation support arm 11 includes a floating support arm connection portion 11 a that is rotatably connected to the floating support arm 10, and a second engagement member connection portion that is rotatably connected to the second engagement member 4. 11b.

  Further, the rotation support arm 11 is supported by the car door 1 so as to be rotatable about a portion between the floating support arm connection portion 11a and the second engagement member connection portion 11b. That is, the intermediate portion of the rotation support arm 11 is rotatably connected to the fixed shaft 12 fixed to the base plate 2.

  The rotation center of the rotation support arm 11, that is, the fixed shaft 12 and the first engagement member connecting portion 10a are arranged at the same position in the vertical direction. The fixed shaft 12, the floating support arm connecting portion 11a, and the first engaging member connecting portion 10a have the floating supporting arm connecting portion 11a as the apex regardless of the distance between the first and second engaging members 3 and 4. Construct an isosceles triangle.

  A guide mechanism 13 is provided between the base plate 2 and the first engagement member 3 to limit the movement of the first engagement member 3 in the horizontal direction. The guide mechanism 13 has a structure in which a guide pin 14 fixed to the first engagement member 3 is fitted into a slit 2 a provided in the base plate 2. The slit 2 a is provided in parallel to the opening / closing direction of the car door 1.

  Further, the guide mechanism 13 supports the weight of the first engagement member 3 and tries to lift the first engagement member 3 transmitted from the rotation support arm 11 by the weight of the second engagement member 4. Supporting the force, the driving belt 7 is prevented from being bent and the vertical positional relationship between the first engaging member connecting portion 10a and the fixed shaft 12 is prevented from shifting.

  A cam portion 11 c is provided at an intermediate portion of the rotation support arm 11. A lock part (step part) 11d is provided at the end of the cam part 11c. A latch 15 that engages with the cam portion 11 c of the upper interlocking link mechanism 8 is rotatably attached to the base plate 2. A pressing spring 16 that presses the latch 15 against the cam portion 11 c is provided between the base plate 2 and the latch 15.

  When the first engagement member 3 is displaced in the door opening direction and the rotation support arm 11 is rotated counterclockwise in FIG. 1, the latch 15 is engaged with the lock portion 11d as shown in FIG. . Thereby, the rotation of the rotation support arm 11 in the clockwise direction in FIG. 2 is restricted, and even if the drive belt 7 is moved in the door closing direction, the engagement rollers of the first and second engagement members 3, 4. 5 is maintained.

  The car is provided with a lock releasing rod 17 for releasing the engagement of the latch 15 with the lock portion 11d. When the car door 1 is moved in the door closing direction from the state of FIG. 2, the end of the latch 15 is brought into contact with the lock release rod 17. When the car door 1 is further moved in the door closing direction, the rotation support arm 11 is rotated counterclockwise in FIG. 2 against the push spring 16, and the latch 15 is engaged with the lock portion 11d. Canceled.

  Next, the operation will be described. When the drive motor is rotated in the door opening direction from the door closed state in FIG. 1, the drive belt 7 attached to the motor shaft via a pulley (not shown) is moved in the door opening direction, and the first engagement is achieved. The joint member 3 is also moved in the door opening direction. As a result, the floating support arm connecting portion 11a is pushed up, the rotation support arm 11 is rotated about the fixed shaft 12 in the counterclockwise direction in the figure, and the second engagement member 4 is pushed out in the door closing direction. .

  By such a movement, when the door is opened, the interval between the first and second engaging members 3 and 4 is reduced with the rotation of the drive motor, and the first and second engaging members 3 and 4 as shown in FIG. In the meantime, the engaging roller 5 is restrained. When the driving belt 7 is further moved in the door opening direction from the state of FIG. 2, the force of the driving belt 7 is transmitted to the car door 1, and the car door 1 and the landing door start to open.

  During the opening operation of the car door 1, since the latch 15 is engaged with the lock portion 11d, the first and second engaging members 3 and 4 are opened even if a force is applied in the door closing direction due to a disturbance. Rather, the movement of the car door 1 and the movement of the landing door are consistently matched.

  When the door is closed, the drive belt 7 is moved in the door closing direction by the rotation of the drive motor. At this time, since the latch 15 is engaged with the lock portion 11d and the engaging roller 5 is sandwiched between the first and second engaging members 3 and 4, the movement of the drive belt 7 remains as it is. 1 and the hall door are moved, and the car door 1 and the hall door are moved in the door closing direction.

  Thereafter, when the car door 1 is moved to a position just before the all-closed position, the lock release rod 17 releases the engagement of the latch 15 with the lock portion 11d. For this reason, the landing door loses the restraining force by the first and second engaging members 3 and 4 and loses the force from the drive belt 7 in the door closing direction. However, the landing door is always urged in the door closing direction by a door closer (not shown). For this reason, after the engagement of the first and second engagement members 3 and 4 with the engagement roller 5 is released, the landing doors are all closed by the action of the door closer.

  On the other hand, the car door 1 is fully closed following the movement of the first engagement member 3 due to inertia. Even after the car door 1 is closed and stopped moving, the drive belt 7 is closed in the door closing direction until the first and second engaging members 3 and 4 return to the state shown in FIG. To complete the door closing operation.

  In such an elevator door engaging device, the coupling fitting 6 connected to the drive belt 7 is provided on the first engaging member 3, and the interlocking link mechanisms 8 and 9 are moved by the movement of the drive belt 7. Since one engagement member 3 is displaced parallel to the opening / closing direction of the car door 1, the drive belt 7 can be moved more linearly, and fluctuations in the tension of the drive belt 7 can be suppressed.

  Further, the amount of displacement of the first engagement member 3 in the vertical direction can be reduced, and the installation space for the first engagement member 3 can be reduced to save space. Further, the movement of the first and second engagement members 3 and 4 and the movement of the drive belt 7 can be matched, and the opening and closing speeds of the first and second engagement members 3 and 4 and the car door 1 The opening / closing speed can be easily controlled.

Furthermore, since each interlocking link mechanism 8, 9 is composed of the floating support arm 10 and the rotation support arm 11, the first and second engaging members 3, 4 can be interlocked with a simple configuration. Can do.
Further, the fixed shaft 12 and the first engaging member connecting portion 10a are arranged at equal positions in the vertical direction, and the fixed shaft 12, the floating support arm connecting portion 11a, and the first engaging member connecting portion 10a. Constitutes an isosceles triangle having the floating support arm connecting portion 11a as the apex, so that the first engagement member 3 can be displaced parallel to the opening / closing direction of the car door 1 with a simple configuration.
Furthermore, since the movement of the first engagement member 3 is limited in the horizontal direction by the guide mechanism 13, the first and second engagements are caused by the weights of the first engagement member 3 and the second engagement member 4. It is possible to more reliably prevent the members 3 and 4 from moving up and down.

  Note that the distance between the fixed shaft 12 and the floating support arm connecting portion 11a and the distance between the floating support arm connecting portion 11a and the first engaging member connecting portion 10a are not necessarily equal. When the distance between the fixed shaft 12 and the floating support arm connecting portion 11a is different from the distance between the floating support arm connecting portion 11a and the first engaging member connecting portion 10a, the first engaging member 3 However, it is sufficient to design so that the engagement is completed within this moving range.
