  • the door opening/closing unit 7 is mounted at a front top portion of a passenger car.
  • the car door 8 suspended by a suspension member 7a is adapted to be opened and closed by means of an electric motor 7c which is operatively connected to the car door 8 through the medium of an interlink rope 7b.
  • a car door engaging member 8b serving as the vibration damping member is disposed at the position corresponding to a hall door unit 10.
  • the car door engaging member 8b is implemented in a substantially C-like cross-section and extends in the up/down direction of the passenger car.
  • the hall door unit 10 is mounted at a front top portion of a hall.
  • a suspension rail 10e is so disposed as to be sandwiched between a roller 10c and a roller 10d while a hall door 10b suspended on the suspension rail 10e is adapted to be movable in the left/right direction along the suspension rail 10e.
  • a hall door engaging member 10a serving as the vibration damping member is disposed at the position corresponding to the door opening/closing unit 7.

  • the hall door 10b is also opened/closed in linkage with the movement of the car door 8.
  • the driving force of the electric motor 7c is intensified to an appropriate magnitude. Accordingly, the driving force of the door opening/closing unit 7, i.e., the driving force of the electric motor 7c, is transmitted to the hall door 10b defining the lift path by way of the engaging members 8b and 10a. In this manner, shaking of the passenger car can be suppressed.

More specifically, the frictionally slidable member 8c is provided on a surface 8b1 of the car door engaging member 8b implemented substantially in a C-like cross-section which surface is pushed against the hall door engaging member upon opening of the car door and a surface 8b2 which is pushed upon closing of the car door.
  • the frictional force of the engaging members 8b and 10a increases, whereby the vibration of the passenger car is further damped.
  • vibration of the passenger car can be attenuated even in the course of opening or closing the door or in the state in which the door is held fully opened.
  • the frictionally slidable members 8c may be provided in combination with either the car door engaging member 8b or the hall door engaging member 10a.
  • the car door engaging member 8b is shorter than the hall door engaging member 10a, it is preferred to provide the frictionally slidable member 8c for the car door engaging member 8b because then the frictionally slidable member 8c can be formed in a reduced size inexpensively.
  • the vibration damping apparatus for the elevator system there can be expected no more than the vibration damping effectuated by the frictional force equivalent to the door weight of the car door and the hall door in the course of operation for opening the doors.
  • the pushing force in the state where the door is fully opened can be regulated with high degree of freedom by adjusting the driving force of the electric motor 7c.
  • each of the car door and the hall door includes a plurality of rollers which are so arrayed as to sandwich the suspension rail in the vertical direction.
  • vibration of the passenger car in the state where the car door engaging member 8b and the hall door engaging member 10a engage with each other will cause the doors to move within the range delimited by the gap, giving rise to jolting, vibration and noise while possibly involving damage to the life of the machinery.
  • the rollers by disposing the rollers on and under the rail for guiding the door upon opening/closing thereof while sandwiching the rail between the rollers, there can be realized the structure in which the gap is blocked up.
  • FIG. 5 is a front view showing a door opening/closing unit of the elevator system according to a third embodiment of this invention.
  • Figure 6 is a front view of a hall door unit.
  • a car door 8 is provided with a fixed clamping member 8d and a movable clamping member 8e which cooperate to constitute a clamping device or unit.

  • a frictionally slidable member not shown is provided on each of the opposite surfaces of the fixed clamping member 8d and the movable clamping member 8e.
  • the hall door engaging member 10f includes a row of rollers arrayed along the up/down direction of the passenger car.
  • both the clamping members 8d and 8e are still opened or separated widely at the beginning of the door opening operation.
  • the movable clamping member 8e is forced to move toward the fixed clamping member 8d by means of a cam 8f till the hall door engaging member 10f is fixedly held by the fixed clamping member and the movable clamping member, being sandwiched therebetween.
  • the shape of the cam 8f is so determined that the holding force exerted by the movable clamping member 8e remains constant even when the car door 8 is completely opened.
  • the cam 8f can move in accompanying the opening/closing operation of the car door 8 owing to a link 8h by means of which a pin 7d provided on the door opening/closing unit 7 and a pin 8g provided on the car door 8 are linked to each other. Further, owing to this arrangement, the cam 8f can produce a clamping or gripping force of appropriate magnitude.
  • the clamping unit may be provided on the side of the elevator hall or the elevator shaft.
  • the hall door engaging member 10f is implemented in the form of the roller array, it goes without saying that similar action and effect can be achieved even when a flat plate is employed instead of the rollers.
  • the frictionally slidable member is formed of a polyurethane resin. Since the polyurethane resin exhibits enhanced friction characteristic and is excellent in respect to the abrasion resistance as well, sufficient vibration damping effect can be expected even when the opening force of the door opening/closing unit is small. Thus, not only miniaturization of the machinery can be realized but also use over an extended period can be ensured. Besides, because hardness of the frictionally slidable member can be selected with high degree of freedom, the action for buffering collision noise generated at the engaging portion can be regulated with high degree of freedom, whereby enhanced vibration damping effect and silentness feature can compatibly be realized.
  • the frictionally slidable member may be formed of a macromolecular polyurethane resin.
  • the macromolecular polyurethane resin is capable of exhibiting stabilized vibration damping characteristic because of substantially no significant difference between the static friction characteristic and the dynamic friction characteristic.
  • the macromolecular polyurethane resin is excellent in the abrasion resistance and thus can be used over an extended period. Although the coefficient of friction is not excessively large, the macromolecular polyurethane resin can ensure an excellent silentness feature.
  • the macromolecular polyurethane resin is also advantageously suited for use in the vibration damping apparatus installed at a location in the vicinity of the elevator hall where many passengers come and go.
