Definitions

  • the present invention relates to a door engaging device for driving a car door and a landing door of an elevator in synchronization.
  • first and second runners are interlocked by a pair of link mechanisms to be engaged with and disengaged from an engagement roller of a landing door.
  • Each of the link mechanisms includes an adjusting element turnably provided to a car door and an articulation member turnably connected to one end of the adjusting element.
  • Each of the articulation members is turnably connected to the first runner.
  • the other end of each of the adjusting elements is turnably connected to the second runner.
  • the adjusting elements are connected to a drive belt which is circulated by a drive motor. Then, the circulation of the drive belt turns the adjusting elements to open and close the first and second runners (for example, see Patent Document 1).
  • the drive belt is connected to the adjusting elements, and the circulation of the drive belt turns the adjusting elements. Therefore, a connecting portion of the drive belt to each of the adjusting elements is pushed down from an ideal straight track by the turn of the adjusting elements. As a result, a tension of the drive belt is increased. Moreover, the first and second runners are vertically displaced while being opened and closed, and hence it is necessary to ensure an escape space above and below the first and second runners. Further, an operation of the drive belt is transferred to the first and second runners through the adjusting elements, and hence the movement of the drive belt is not in synchronization with that of the first and second runners. Thus, it is difficult to adjust a speed of opening and closing the first and second runners.
  • the present invention is devised to solve the problems described above, and has an object of providing a door engaging device for an elevator, which is capable of more linearly moving a power transmission body, reducing the amount of vertical displacement of first and second engagement members, and synchronizing movement of the first and second engagement members with that of the power transmission body.
  • a door engaging device for an elevator includes: a first engagement member and a second engagement member provided to a car door to be engaged with a landing door-side engagement portion provided to a landing door by changing a distance therebetween in a direction in which the car door opens and closes; and a plurality of interlocking link mechanisms provided to the car door at a vertical distance from each other to support the first engagement member and the second engagement member and displace the first engagement member and the second engagement member in an interlocked manner, thereby changing the distance between the first engagement member and the second engagement member, in which the first engagement member is provided with a transmission body connecting portion to be connected to a power transmission body moved in the direction in which the car door opens and closes by a drive motor for opening and closing the car door, and the interlocking link mechanisms displace the first engagement member in parallel to the direction in which the car door opens and closes by movement of the power transmission body.
  • FIG. 1 is a front view illustrating a door engaging device for an elevator according to a first embodiment of the present invention as viewed from a landing side.
  • a base plate 2 is fixed to an upper part of a car door 1.
  • a first engagement member (driving-side engaging vane) 3 and a second engagement member (driven-side engaging vane) 4 are provided to the base plate 2. Longitudinal directions of the first engagement member 3 and the second engagement member 4 are vertically parallel to each other.
  • the first engagement member 3 and the second engagement member 4 are arranged at a distance from each other in a direction in which the car door 1 opens and closes (horizontal direction of FIG. 1 ).
  • the distance between the first engagement member 3 and the second engagement member 4 is variable.
  • an engagement roller 5 corresponding to a landing door-side engagement portion provided to a landing door (not shown) is positioned between the first engagement member 3 and the second engagement member 4.
  • a reduction of the distance between the first engagement member 3 and the second engagement member 4 allows the first engagement member 3 and the second engagement member 4 to be engaged with the engagement roller 5, that is, to interpose the engagement roller 5 therebetween, as illustrated in FIG. 2 .
  • the car door 1 and the landing door are moved in synchronization.
  • an increase of the distance between the first engagement member 3 and the second engagement member 4 disengages the first engagement member 3 and the second engagement member 4 from the engagement roller 5, as illustrated in FIG. 1 .
  • a connection fitting 6 corresponding to a transmission body connecting portion is fixed to an upper part of the first engagement member 3.
  • An upper end of the connection fitting 6 is connected to a drive belt 7 corresponding to a power transmission body.
  • the drive belt 7 is circulated by a drive motor (not shown) corresponding to a drive source for opening and closing the car door 1.
  • a connecting portion of the drive belt 7 to the connection fitting 6 is moved in a direction in which the car door 1 opens and closes.
  • an operation of the drive belt 7 is transmitted to the car door 1 through operations of the first engagement member 3 and the second engagement member 4.
  • the first engagement member 3 and the second engagement member 4 are supported on the base plate 2 through an intermediation of an upper interlocking link mechanism 8 and a lower interlocking link mechanism 9.
  • the interlocking link mechanisms 8 and 9 are mounted to the base plate 2 at a vertical distance from each other.
  • the interlocking link mechanisms 8 and 9 displace the first engagement member 3 and the second engagement member 4 in an interlocked manner to change the distance between the first engagement member 3 and the second engagement member 4. Further, the interlocking link mechanisms 8 and 9 displace, by the movement of the drive belt 7, the first engagement member 3 in a direction parallel to the direction in which the car door 1 opens and closes.
  • Each of the interlocking link mechanisms 8 and 9 includes a floating support arm 10 and a turning support arm 11.
  • the floating support arm 10 includes a first engagement member connecting portion 10a turnably connected to the first engagement member 3.
  • the turning support arm 11 includes a floating support arm connecting portion 11a turnably connected to the floating support arm 10 and a second engagement member connecting portion 11a turnably connected to the second engagement member 4.
  • Each of the turning support arms 11 is supported on the car door 1 to be turnable on a portion between the floating support arm connecting portion 11a and the second engagement member connecting portion 11b. Specifically, an intermediate portion of each of the turning support arms 11 is turnably connected to a fixed shaft 12 fixed to the base plate 2.
  • a center of the turn of each of the turning support arms 11, that is, the fixed shaft 12, and the first engagement member connecting portion 10a are located at the positions which are equal in a vertical direction.
  • the fixed shaft 12, the floating support arm connecting portion 11a, and the first engagement member connecting portion 10a form an isosceles triangle having the floating support arm connecting portion 11a as an apex regardless of the distance between the first engagement member 3 and the second engagement member 4.
  • a guide mechanism 13 for limiting the movement of the first engagement member 3 to a horizontal direction is provided between the base plate 2 and the first engagement member 3.
  • 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 2a provided in the base plate 2.
  • the slit 2a is provided to be parallel to the direction in which the car door 1 opens and closes.
  • the guide mechanism 13 supports a weight of the first engagement member 3 and also supports a force of lifting up the first engagement member 3, which is transmitted from the turning support arms 11 by a weight of the second engagement member 4, to prevent the drive belt 7 from being deflected to misalign the position of the first engagement member connecting portion 10a and that of the fixed shaft 12 from each other in a vertical direction.
  • a cam portion 11c is provided to the intermediate portion of each of the turning support arms 11. At an end of the cam portion 11c, a lock portion (step portion) 11d is provided.
  • a latch 15 to be engaged with the cam portion 11c of the upper interlocking link mechanism 8 is turnably attached to the base plate 2.
  • a compression spring 16 for pressing the latch 15 against the cam portion 11c is provided between the base plate 2 and the latch 15.
  • the car is provided with an unlock rod 17 for disengaging the latch 15 from the lock portion 11d.
  • an end of the latch 15 abuts against the unlock rod 17.
  • the turning support arm 11 is turned in the counterclockwise direction of FIG. 2 against the compression spring 16 to disengage the latch 15 from the lock portion 11d.
  • the latch 15 is engaged with the lock portion 11d. Therefore, even when a force is applied in the door-closing direction due to a disturbance, the first engagement member 3 and the second engagement member 4 do not open. Therefore, the movement of the car door 1 and the movement of the landing door are stably in synchronization.
  • the drive belt 7 is moved in the door-closing direction by the rotation of the drive motor.
  • the latch 15 is engaged with the lock portion 11d and the engagement roller 5 is interposed between the first engagement member 3 and the second engagement member 4, and hence the movement of the drive belt 7 is directly transmitted to the car door 1 and the landing door.
  • the car door 1 and the landing door are moved in the door-closing direction.
  • the latch 15 is disengaged from the lock portion 11d by the unlock rod 17.
  • the landing door loses a fixing force by the first engagement member 3 and the second engagement member 4 to lose a force in the door-closing direction from the drive belt 7.
  • the landing door is constantly biased in the door-closing direction by a door closer (not shown). Therefore, after the first engagement member 3 and the second engagement member 4 are disengaged from the engagement roller 5, the landing door is fully closed by a function of the door closer.
  • the car door 1 follows the movement of the first engagement member 3 due to inertia to be fully closed. Even after the car door 1 is fully closed to be unmovable, the drive belt 7 moves in the door-closing direction until the first engagement member 3 and the second engagement member 4 return to the state illustrated in FIG. 1 with the movement in the direction opposite to that performed when the door opens, thereby completing the door closing operation.
  • connection fitting 6 to be connected to the drive belt 7 is provided to the first engagement member 3, whereas the interlocking link mechanisms 8 and 9 displace the first engagement member 3 in parallel to the direction in which the car door 1 opens and closes, by the movement of the drive belt 7. Therefore, the drive belt 7 can be more linearly moved to prevent the tension of the drive belt 7 from being fluctuated.
  • the amount of vertical displacement of the first engagement member 3 can be reduced. Therefore, a space for locating the first engagement member 3 can be reduced to achieve space-saving. Further, the movement of the first engagement member 3 and the second engagement member 4 can be synchronized with the movement of the drive belt 7. As a result, a speed of opening and closing the first engagement member 3 and the second engagement member 4 and a speed of opening and closing the car door 1 can be easily controlled.
  • each of the interlocking link mechanisms 8 and 9 includes the floating support arm 10 and the turning support arm 11, and hence the first engagement member 3 and the second engagement member 4 can be interlocked with each other in a simple structure.
  • the fixed shaft 12 and the first engagement member connecting portion 10a are located at the positions which are equal in the vertical direction.
  • the fixed shaft 12, the floating support arm connecting portion 11a, and the first engagement member connecting portion 10a form the isosceles triangle having the floating support arm connecting portion 11a as the apex. Therefore, with the simple structure, the first engagement member 3 can be displaced in parallel to the direction in which the car door 1 opens and closes. Further, the movement of the first engagement member 3 is limited by the guide mechanism 13 to the horizontal direction, and hence the vertical movement of the first engagement member 3 and the second engagement member 4 due to the weight of the first engagement member 3 or the second engagement member 4 can be more surely prevented.
  • 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 engagement member connecting portion 10a are not necessarily required to be equal to each other.
  • the range in which the first engagement member 3 can horizontally move is reduced.
  • FIG. 3 is a front view illustrating a door engaging device for an elevator according to a second embodiment of the present invention as viewed from the landing side.
  • a guide mechanism 18 for limiting the movement of the first engagement member 3 to the horizontal direction is provided between the base plate 2 and the first engagement member 3.
  • the guide mechanism 18 includes a guide plate 19 provided to the base plate 2 and a guide roller 20 provided to the first engagement member 3, which is rolled along an upper surface of the guide plate 19.
  • the upper surface of the guide plate 19 is provided in parallel to the direction in which the car door 1 opens and closes.
  • the remaining configuration is the same as that of the first embodiment.
  • the guide mechanism 18 for restricting only the downward displacement of the first engagement member 3 can be used. In this case, it is not necessary to fit the guide pin 14 into the slit 2a as in the first embodiment, and therefore, it is not necessary to adjust a clearance between the slit 2a and the guide pin 14. Thus, the positional adjustment at the time of fabrication and assembly of the components can be simplified.
  • a guide mechanism obtained by vertically inverting the guide mechanism 18 illustrated in FIG. 3 may be used.
  • the guide roller 20 is rolled along a lower surface of the guide plate 19, and only the upward displacement of the first engagement member 3 is restricted by the guide mechanism 18.
  • FIG. 4 is a front view illustrating a door engaging device for an elevator according to a third embodiment of the present invention as viewed from the landing side.
  • the guide mechanism 13 in the first embodiment is omitted.
  • the remaining configuration is the same as that of the first embodiment.
  • the guide mechanisms 13 and 18 may be omitted as illustrated in FIG. 4 .
  • the first engagement member 3 can be horizontally moved using the drive belt 7 itself as a guide. As a result, the device can be simplified, while the cost thereof can be reduced.
  • FIG. 5 is a front view illustrating a door engaging device for an elevator according to a fourth embodiment of the present invention as viewed from the landing side.
  • the first engagement member 3 and the second engagement member 4 are supported on the base plate 2 through an intermediation of an upper interlocking link mechanism 21 and a lower interlocking link mechanism 22.
  • the interlocking link mechanisms 21 and 22 are mounted to the base plate 2 at a vertical distance from each other.
  • the interlocking link mechanisms 21 and 22 displace the first engagement member 3 and the second engagement member 4 in an interlocked manner to change the distance between the first engagement member 3 and the second engagement member 4. Further, the interlocking link mechanisms 21 and 22 displace, by the movement of the drive belt 7, the first engagement member 3 in parallel to the direction in which the car door 1 opens and closes.
  • the upper interlocking link mechanism 21 and the lower interlocking link mechanism 22 have the same structure.
  • Each of the interlocking link mechanisms 21 and 22 has a first floating support arm 23, a second floating support arm 24, and a turning support arm 25 connected between the first floating support arm 23 and the second floating support arm 24.
  • the first floating support arm 23 includes a first engagement member connecting portion 23a which is turnably connected to the first engagement member 3.
  • the second floating support arm 24 includes a second engagement member connecting portion 24a which is turnably connected to the second engaging member 4.
  • the turning support arm 25 includes a first floating support arm connecting portion 25a turnably connected to the first floating support arm 23 and a second floating support arm connection portion 25b turnably connected to the second floating support arm 24.
