It is a flowchart which shows operation | movement of the falling object collection | recovery operation system of the elevator apparatus shown in FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a floor stop state in an elevator apparatus according to an embodiment of the present invention. A car 1 that moves in a hoistway 2 is provided with an openable and closable car door. There is a platform door that can be opened and closed for each floor. Normally, the car door moves along the threshold of the car 1, and the landing door is opened and closed in conjunction with the opening and closing of the car door, and between the car 1 and the floor landing side 3 A gap is formed in.

  A receiving part 5 having a size corresponding to the width and length of the gap is arranged below the threshold gap between the car 1 and the floor landing side 3. It is connected to a drive mechanism 6 that performs a folding operation along an apron 4 that extends downward from the lower portion of the car 1. On the other hand, the hoistway wall at each floor platform side 3 is provided with a collection box 7 with an opening at the upper part, and this collection box 7 can be seen even if the car door is opened in the normal operation of the elevator. It is installed in a position where it cannot be A lid 8 whose lower part can be opened and closed to the collection box 7 by a hinge or the like so as to open downward is attached to the car 1 side of the collection box 7, and this lid 8 is normally closed. .

  FIG. 4 is an enlarged view showing a schematic configuration of the receiving part 5 and the drive mechanism 6 described above. One end of the receiving part 5 is rotatable by the rotating shaft 11 in the apron 4 arranged at the lower part of the car 1. It is connected to. A position holding spring 14 is provided between the receiving part 5 and the apron 4 on the free end side, and in a steady state, the position holding spring 14 positions the free end side of the receiving part 5 so as not to interfere with the hoistway wall. It has been displaced. One end of an electromagnetic drive member 12 is connected to the intermediate portion of the receiving portion 5, and an electromagnetic coil 13 is arranged corresponding to the electromagnetic drive member 12 and is excited in conjunction with the opening operation of the car door. Has been placed. When the electromagnetic coil 13 is excited, the electromagnetic driving member 12 is driven rightward in the drawing, and the free end of the receiving portion 5 is displaced toward the hoistway wall against the position holding spring 14. Here, the drive mechanism 6 is constituted by the electromagnetic drive member 12, the electromagnetic coil 13, and the position holding spring 14.

  After the car 1 stops at a position corresponding to the floor landing side 3, when the car door of the car 1 is opened, the drive mechanism 6 is connected to the receiving portion 5 via the electromagnetic drive member 12 in conjunction with this. Move the free end side to the hoistway side. The free end side of the catching portion 5 is located on the hoistway wall side with respect to the gap existing between the car 1 and the floor landing side 3 and is inclined as a whole. At this time, the hoistway wall side of the receiving part 5 corresponds to the upper charging port of the collection box 7 provided on the hoistway wall. Therefore, in this state, if an accessory is dropped from the gap between the sills existing between the car 1 and the floor landing side 3, it can be received by the receiving portion 5 and then collected in the collection box 7 It will fall in.

  Although the shape of the receiving part 5 is not ask | required, when falling objects fall on it as mentioned above, it is desirable to make it the shape which is easy to guide in the collection box 7 smoothly.

  On the other hand, as shown in FIG. 3, an operation panel switch box 9 containing switches of equipment related to the car 1 is configured in the car 1, and is normally unlocked by a maintenance worker. Although it opens, here, it is provided with switching means 10 such as a wave switch that can be unlocked also by a building manager and operated when performing falling object recovery operation. In another embodiment, the switching means 10 for falling object collecting operation is configured in the car 1 separately from the operation panel switch box 9, and the switching means 10 including the unlocking can be operated by the building manager. You may do it.

  When the switching means 10 is operated to the falling object recovery operation side, the falling object recovery operation system is activated. When this fallen object recovery operation system is activated, the maintenance light on the indicator is turned on, all hall calls are disabled, and only the operation buttons in the car 1 are enabled. When a desired floor is designated from within the car 1, the car 1 moves to a position slightly below the normal floor stop state, stops, and can take a position corresponding to the collection box 7. In addition, when the door opening button for opening the car door in the car 1 is operated, the car door can be opened, while the door closing button for closing the car door in the car 1 is opened. When operated, the car door can be closed. Further, when the switching means 10 is switched to the normal operation side, the falling object recovery operation system stops and returns to the normal operation end.

  When the normal car 1 is raised and lowered, the coil 13 shown in FIG. 4 is not excited, so that the free end side of the receiving portion 5 interferes with the hoistway wall by the position holding spring 14 as shown in FIG. It is kept in the state without. However, when the car 1 stops at a position corresponding to the floor landing side 3 in the normal floor stop state shown in FIG. 1 and the car door is opened, the drive mechanism 6 operates in conjunction with this, The lower end of the receiving part 5 is moved to the hoistway wall side and inclined, that is, the state shown in FIG. At this time, the end portion of the receiving portion 5 located on the hoistway wall side substantially corresponds to the upper charging port of the collection box 7 provided on the hoistway wall. Thereafter, when the car 1 eventually closes the car door, as shown in FIG. 2, the driving mechanism 6 returns to a steady state and becomes a non-excited state in conjunction with the closing operation of the car door. Also, the car 1 is returned to a state that does not hinder the raising and lowering of the car 1.

  Now, with the normal floor stop state shown in FIG. 1, the car door is opened, and the drive mechanism 6 operates in conjunction with this to move the lower free end side of the receiving portion 5 to the hoistway wall side. It is assumed that in the inclined state, a passenger drops some small articles when entering or leaving the car 1 and drops downward from a gap between the car 1 and the floor landing side 3. Then, the fallen object is first received by the receiving part 5, moves on the inclined surface, and is then recovered into the recovery box 7 attached to the hoistway wall.

  After that, when a passenger who has dropped an accessory collects it, he / she reports it to the building manager rather than requesting the elevator maintenance company to dispatch a maintenance worker. At this time, the building manager gets into the car 1, unlocks the operation panel switch box 9 of FIG. 3 provided in the car, and operates the switching means 10 such as the wave switch to the falling object recovery operation side. Then, the falling object recovery operation system is activated.

  The subsequent procedure will be described with reference to the flowchart shown in FIG.

  When it is detected in step S1 that the switching means 10 has been operated, the elevator is switched from the normal operation to the falling object recovery operation. The falling object recovery operation system turns on the maintenance lamp of the indicator in step S2, invalidates all hall calls in step S3, and validates only the button operation in the car 1.

  Thus, the building manager designates the floor when the accessory is dropped by operating the destination floor button in the car 1. Then, the falling object recovery operation system detects the destination call registration in step S4, moves the car 1 in step S5, and stops it at a position slightly below the normal floor stop as shown in FIG. Thereafter, when the building manager operates the door opening button in the car 1, this operation is detected in step S6, and the car door is opened in step S7.

  In this fallen object recovery operation, the electromagnetic coil 13 shown in FIG. 4 is not excited in conjunction with the opening of the car door, so that the receiving portion 5 does not operate as when stopped during normal operation, It remains in the stowed state. Also, the landing door on the floor platform side will not be opened. When the car door is opened, the collection box 7 appears immediately in front of you. Therefore, the building manager collects the fallen object while opening the door 8 and observing it, and closes the lid 8 of the collection box 7 to return it to the original state.

  Thereafter, when the building manager switches the switching means 10 in the operation panel switch box 7 of FIG. 3 to the normal operation side, this is detected in step S8, and the elevator stops the falling object recovery operation system in step S9. Switch to normal operation.

  According to such an elevator apparatus, the collection boxes 7 are respectively installed facing the car doors on the inner wall of the hoistway 2 located at the lower part of each floor landing side 3, and the car 1 and the floor landing side 3 are connected to each other. A catching part 5 that receives fallen objects from a gap existing between them is provided on the car 1 side, and the catching part 5 is driven obliquely in conjunction with the opening operation of the car door at the floor stop position by steady operation and dropped. Since the drive mechanism 6 is provided for returning the object to the collection box 7 and returning to the original state in conjunction with the closing operation of the car door, the raising and lowering of the car 1 is not affected when the car door is closed. In a situation where there is a possibility of falling from the gap between the car 1 and the floor landing side while holding the receiving part 5 in a state, the receiving part 3 is moved to reliably receive the fallen object and return to the collection box 5 I can guide you. In addition, since the collection box 5 is provided for each floor platform, the distance to drop the fallen object is reduced, and the possibility of damaging the fallen object can be reduced.

  In the elevator apparatus according to this embodiment, switching means 10 such as a switch for switching to the falling object collecting operation is provided in the car 1, and the falling object collecting operation system is operated when the switching means 10 is switched to the falling object collecting operation side. Although the description has been made on the assumption that the configuration is to be performed, it is possible to obtain substantially the same effect even if maintenance operation is performed instead of the falling object recovery operation system and the car 1 is moved little by little to correspond to the recovery box 7. it can. In addition, the drive mechanism 6 described in FIG. 4 is not limited to the illustrated configuration, and various other configurations can be used.

  Further, according to the elevator apparatus described above, the switching means 10 such as a switch for switching to the falling object recovery operation is provided in the car 1, and when this switching means 10 is switched to the falling object recovery operation side, all hall calls are made. When disabled, only the operation buttons in the car 1 are enabled, and when a desired floor is designated from the car 1, the car 1 is stopped at the position corresponding to the collection box 7, and the door open / close button in the car 1 Because the fall object recovery operation system that allows the car door to be opened and closed by operating the car is stopped at the position corresponding to the recovery box 7 and the car door is opened, the recovery box can be easily accessed from the car 1 side. The falling object in 7 can be collected. Moreover, since the switching means 10 can be operated by the building manager without requesting the maintenance worker to be dispatched, it is possible to easily switch to the falling object recovery operation and to recover the falling object from the car 1 side in a short time. it can. Furthermore, unlike the normal operation, this falling object collection operation system opens only the car door of the car 1 and does not open the car door on the floor landing side 3, so that the floor landing side 3 is safe as before. Therefore, it is not necessary to arrange a fence or the like, and the work can be easily performed.
