Definitions

  • the present invention relates to an unlocking apparatus of elevator hall door which unlocks an elevator hall door from the hall side and a method of modifying an unlocking apparatus.
  • the former type of construction differs from the latter type of construction in the installation position of a keyhole mouthpiece provided on a back face of the upper part of a hall door.
  • a key removing rod (not shown) is vertically operated
  • the position of a T-shaped keyhole mouthpiece 3 is in the same position as the bottom end of an unlocking lever 2 in terms of plane and the bottom end of the unlocking lever 2 is pushed up by the key removing rod which has been inserted, thereby to unlock a locking device 4 provided above the top end portion of a hall door 1.
  • the present invention has been made to solve such a conventional problem and has as its object the provision of an unlocking apparatus of elevator hall door which permits a modification into an unlocking apparatus of such a construction that permits unlocking by turning a triangular key instead of the vertical operation of a key removing rod without changing the installation position of a keyhole mouthpiece, and a method of modifying an unlocking apparatus.
  • EP 1 100 900 A1 is a prior art document which relates to a shaft safety system for an elevator. It discloses a shaft safety device including a triangle key lock in a landing door panel, wherein a lever coupled to the triangle key lock lifts a mechanism when the triangle key lock is manually operated. In turn, this will rotate a door latch that is connected to the door hanger. According to this prior art document, this helps in safeguarding a maintenance worker in the work environment from the car.
  • the present invention provides an unlocking apparatus of elevator hall door, which is used in modifying an unlocking apparatus of elevator hall door of such a construction that, with an unlocking keyhole mouthpiece having a keyhole into which a key removing rod is inserted being fixed to a back side of the elevator hall door, an unlocking lever is pushed up by vertically operating the key removing rod, thereby to unlock a locking device of the hall door into an unlocking apparatus in which unlocking is performed by turning a triangular key instead of the vertical operation of the key removing rod.
  • This unlocking apparatus of elevator hall door is characterized in that the unlocking apparatus of elevator hall door comprises a working piece which is provided in the same place as the unlocking keyhole mouthpiece on the back side of the hall door having a keyhole into which the key removing rod is inserted, and which has a keyhole mouthpiece into which a triangular key is inserted, a working lever which is fixed to this working piece and on the working end side of which a working pin is provided, and a trigger which is provided between the working pin of this working lever and a connecting member of the locking device of the hall door and connects the two together.
  • the working pin of the working lever in the unlocking condition during the ordinary opening and closing of the hall door, is positioned in the middle of the elongated hole of the trigger even when the engaging condition of the locking device of the hall door is undone and the connecting member and the trigger move downward.
  • the working lever does not turn and can be kept at a standstill in a horizontal position.
  • Figure 1 is an upper rear elevation which shows the locking condition of an unlocking apparatus of elevator hall door in the first embodiment of the present invention.
  • Figure 2 is an upper rear elevation which shows the unlocking condition of an unlocking apparatus of elevator hall door in the first embodiment of the present invention.
  • Figure 3 is a sectional view, as viewed from above, of the part of a working pin of an unlocking apparatus of elevator hall door in the first embodiment of the present invention.
  • Figure 4 is a sectional view, as viewed from side, of the part of a working pin of an unlocking apparatus of elevator hall door in the first embodiment of the present invention.
  • Figure 5 is an upper rear elevation which shows the unlocking condition of an unlocking apparatus of elevator hall door in the first embodiment of the present invention during ordinary opening and closing.
  • Figure 6 is an upper rear elevation which shows an example of a conventional unlocking apparatus of elevator hall door.
  • an elevator hall door 1 which opens and closes an elevator entrance enclosed by a hall three-side frame is of such a construction that during the maintenance and inspection of an elevator, a key removing rod (not shown) is inserted from a keyhole in the front face of the hall door 1 into a T-shaped keyhole mouthpiece 3 provided in an upper rear face, and an unlocking lever 2 is pushed up by vertically operating this key removing rod, whereby a locking device 4 provided above the top end of the hall door 1 is unlocked.
  • This locking device 4 is constituted by an engagement protruding member 6 fixed to a hanger case 5, and a lock member 9 which is mounted on a door hanger 7 fixed to the tope end portion of the hall door 1 so as to be able to swing vertically via a pivotal pin 8, and one leading end portion of which constantly engages with the above-described engagement protruding member 6 by its own weight.
  • the other leading end portion of this lock member 9 on the opposite side is provided with a connecting member 10, with the pivotal pin 8 sandwiched.
  • an elongated hole 16 into which the working pin 14 is inserted is provided in the bottom end portion of this trigger 15. And because the working pin 14 is inserted and disposed near the bottom end portion of this elongated hole 16, as shown in Figure 5 , the movement of the connecting member 10 and the trigger 15 during the ordinary opening and closing of the hall door 1 is within the range of upward runout (allowance) by the elongated hole 16 provided in the trigger 15 and does not interfere with the working pin 14. For this reason, the working lever 13 does not rotate and can be kept in a condition in which the working lever 13 is at a standstill in a horizontal position.
  • an unlocking apparatus of elevator hall door thus modified, during the maintenance and inspection of an elevator, a triangular key is inserted from the front face of the hall door 1 into the triangular keyhole of the keyhole mouthpiece 11 and turned, whereby the working lever 13 is turned in the direction of an arrow of Figure 1 (the clockwise direction) and the trigger 15 fixed to the connecting member 10 via the working pin 14 at the leading end of the working lever 13 is lowered.
  • This movement causes the connecting member 10 to make a stroke in the direction of an arrow of Figure 1 (the downward direction) and an unlocking condition as shown in Figure 2 is obtained. Therefore, the unlocking lever 2 of the existing unlocking apparatus becomes not used any more and hence it is possible to modify an unlocking apparatus of such a construction that unlocking is performed by turning a triangular key without changing the installation position of the keyhole mouthpiece of the hall door 1.
  • the working lever 13 comes to a standstill owing to a moment due to the right and left mass imbalance of the axis of rotation thereof and owing to the limitation of the range of rotation of the keyhole mouthpiece of the triangular key.
  • an unlocking apparatus of elevator hall door and a method of modifying an unlocking apparatus according to the present invention are suitable for modification work which involves modifying an unlocking apparatus of elevator hall door of such a construction that an unlocking lever is pushed up by vertically operating a key removing rod, thereby to unlock a locking device of the hall door into an unlocking apparatus in which unlocking is performed by turning a triangular key instead of the vertical operation of a key removing rod.
