Abstract
Description
- 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.
- In some of conventional unlocking apparatus of elevator hall door, for example, as disclosed in the
Japanese Patent Laid-Open No. 4-338092 Japanese Utility Model Laid-Open No. 59-42261 - 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. For example, as shown in Figure 6, in an unlocking apparatus in which 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 anunlocking lever 2 in terms of plane and the bottom end of the unlockinglever 2 is pushed up by the key removing rod which has been inserted, thereby to unlock alocking device 4 provided above the top end portion of ahall door 1. In modification work of an elevator which involves modifying an unlocking apparatus of this construction into an unlocking apparatus in which unlocking is performed by turning a triangular key instead of the vertical operation of a key removing rod, for example, as shown in Fig. 7, it is necessary to change the installation position of atriangular keyhole mouthpiece 11 to the right in the figure by a distance d from the bottom end of theunlocking lever 2 and, therefore, it is necessary to change the position of the keyhole of thehall door 1 or to replace thehall door 1, posing the problem that cost increases when the unlocking apparatus is modified. - 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.
- 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.
- As a result of this, it is possible to make 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.
- Also, in the present invention, in the unlocking condition during the ordinary opening and closing of the hall door, the working pin of the working lever 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.
- As a result of this, the working lever does not turn and can be kept at a standstill in a horizontal position.

- The present invention will be described in further detail on the basis of the accompanying drawings.
- 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.
- As shown in Figure 6, in 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 thehall door 1 into a T-shaped keyhole mouthpiece 3 provided in an upper rear face, and anunlocking lever 2 is pushed up by vertically operating this key removing rod, whereby alocking device 4 provided above the top end of thehall door 1 is unlocked. Thislocking device 4 is constituted by anengagement protruding member 6 fixed to ahanger case 5, and alock member 9 which is mounted on adoor hanger 7 fixed to the tope end portion of thehall door 1 so as to be able to swing vertically via apivotal pin 8, and one leading end portion of which constantly engages with the above-describedengagement protruding member 6 by its own weight. The other leading end portion of thislock member 9 on the opposite side is provided with a connectingmember 10, with thepivotal pin 8 sandwiched. In elevator modification work in which an unlocking apparatus of this construction is modified into an unlocking apparatus of such a construction that unlocking is performed by turning a triangular key instead of the vertical operation of a key removing rod, a modification into an unlocking apparatus of elevator hall door in the first embodiment of the present invention as shown in Figure 1 to Figure 5 is carried out. - That is, in Figure 1 to Figure 4, first, because the
unlocking lever 5 is not used any more, the bottom end portion of theunlocking lever 2, which becomes an obstacle, is cut off 2a or theunlocking lever 2 is completely demounted and removed (refer to Figure 1). Next, aworking piece 12 having akeyhole mouthpiece 11 into which a triangular key is inserted is installed in a position on the back face side of a keyhole provided in the existinghall door 1. A workingpin 14 is provided on the working end side of a workinglever 13 fixed to thisworking piece 12. And between the connectingmember 10 of the existing unlocking apparatus and the workingpin 14 of the workinglever 13, there is provided atrigger 15 to connect the two together. Also, anelongated hole 16 into which the workingpin 14 is inserted is provided in the bottom end portion of thistrigger 15. And because the workingpin 14 is inserted and disposed near the bottom end portion of thiselongated hole 16, as shown in Figure 5, the movement of the connectingmember 10 and thetrigger 15 during the ordinary opening and closing of thehall door 1 is within the range of upward runout (allowance) by theelongated hole 16 provided in thetrigger 15 and does not interfere with the workingpin 14. For this reason, the workinglever 13 does not rotate and can be kept in a condition in which the workinglever 13 is at a standstill in a horizontal position. - In 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 thekeyhole mouthpiece 11 and turned, whereby the workinglever 13 is turned in the direction of an arrow of Figure 1 (the clockwise direction) and thetrigger 15 fixed to the connectingmember 10 via the workingpin 14 at the leading end of the workinglever 13 is lowered. This movement causes the connectingmember 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, theunlocking 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 thehall door 1. - Except during the operation of the key, 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. - In the unlocking condition during the ordinary opening and closing of the
hall door 1, even when as shown in Figure 5, the engaging condition of thekey device 4 is undone and thelock member 9 is vertically swung via thepivotal pin 8, with the result that the connectingmember 10 and thetrigger 15 move downward, the workingpin 14 is positioned substantially in the middle of theelongated hole 16 provided in thetrigger 15 and the workingpin 14 does not work. For this reason, the workinglever 13 does not turn and can be kept at a standstill in a horizontal position. - And an additional mass to the working system of the unlocking apparatus is only a mass portion of the
trigger 15. For this reason, it is possible to hold the effect of a modification on the magnitude of a force for causing the unlocking apparatus to work to a very small level. - As described above, 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.
