The pair of car side doors 11A and 11B are supported by the car side door unit 12 and the car side door sills 13 and are openable and closable in a horizontal direction orthogonal to the vertical direction.
Fig. 3 is a front view of the car side door 11A as viewed from the elevator hall side. As shown in fig. 1 and 3, the car side door unit 12 is provided with a car side door guide rail 15, a driving portion 16 (see fig. 1), a belt 17, and a driven pulley 18. The car side door guide 15 extends parallel to the horizontal direction along the opening and closing direction of the pair of car side doors 11A and 11B.
The driving portion 16 is disposed at one end portion of the car side door unit 12 in the horizontal direction, and the driven wheel 18 is disposed at the other end portion of the car side door unit 12 in the horizontal direction. A belt 17 is wound around a drive shaft of the drive unit 16 and a driven pulley 18.
The belt 17 is formed into an endless shape in which both end portions in the longitudinal direction are connected. When the driving portion 16 is driven, the belt 17 is circulated between the driven pulley 18 and the driving shaft of the driving portion 16. At this time, the upper and lower portions of the belt 17 in the up-down direction move in opposite directions to each other. A first coupling member 22 described later is coupled to a return path side, i.e., a lower portion, of the belt 17, and a second coupling member 23 described later is coupled to an outgoing path side, i.e., an upper portion, of the belt 17.
Further, a fixed hook member 34 and a cam member 57 constituting a car-side locking mechanism 30 described later are fixed to the car-side door unit 12. The fixed hook member 34 and the cam member 57 are disposed above the first car side door 11A in the vertical direction when the pair of car side doors 11A and 11B are closed.
Next, the pair of car side doors 11A and 11B will be described. The pair of car side doors 11A and 11B are formed in a rectangular shape. A first door hanger 21A is provided at an upper end portion in the vertical direction of the first car side door 11A, and a second door hanger 21B is provided at a lower end portion in the vertical direction of the second car side door 11B. Further, sliders 14 are provided at lower end portions in the vertical direction of the pair of car side doors 11A and 11B. The slider 14 is slidably engaged with a guide groove provided in the car side door sill 13.
A rotatable moving roller 24 is provided at each of the first door link plate 21A and the second door link plate 21B. The movable roller 24 is slidably engaged with the car side door guide rail 15.
The first door strap 21A has a first coupling member 22, and the second door strap 21B has a second coupling member 23. The first linking member 22 protrudes upward from the upper end portion of the first door hanging plate 21A in the vertical direction. The second coupling member 23 protrudes upward from the upper end portion of the second door link plate 21B in the vertical direction. The first coupling member 22 is coupled to a lower portion of the belt 17, and the second coupling member 23 is coupled to an upper portion of the belt 17.
Therefore, when the driving portion 16 is driven and the belt 17 moves, the pair of car side doors 11A and 11B move in the door opening direction in which they approach each other or in the door closing direction in which they separate from each other via the first coupling member 22 and the second coupling member 23.
The first car side door 11A is provided with a safety plate 25 and a car side lock mechanism 30. The safety contact plate 25 is provided at an end portion on the door closing direction side of the first car side door 11A, i.e., a door stop side end portion 11A close to the second car side door 11B.
The safety contact plate 25 is formed of a long member extending in the vertical direction at a length substantially equal to the vertical length of the first car side door 11A. The safety touch panel is supported by a door stop side end portion 11A of the first car side door 11A via a pair of link members, and is movable in the vertical direction and the opening and closing direction. Further, a detection portion, not shown, for detecting movement of the safety contact plate 25 is provided in the vicinity of a link member supporting the safety contact plate 25 at the door stop side end portion 11A of the first car side door 11A. The detection unit detects the movement of the safety touch panel 25, thereby detecting that a load is applied to the safety touch panel 25.
[ Car side locking mechanism ]
Next, the car-side locking mechanism 30 will be described. As shown in fig. 3, the car-side lock mechanism 30 includes a bottom plate 31, a first car-side engaging piece 32, a locking-side hook member 33, a fixed hook member 34, a rotating shaft 35, a locking holding member 39, and a pair of first link members 41A and 41B. Further, the car-side locking mechanism 30 includes: the second car side engaging piece 52, the cam member 57, the pair of second link members 61A, 61B, and the forced unlocking mechanism 70 operable to the second car side engaging piece 52.
The bottom plate 31 is formed in a substantially flat plate shape. The bottom plate 31 has a main surface portion 31a and a rope support surface portion 31 b. The main surface portion 31A is fixed to the first door hanging plate 21A. The main surface portion 31a is formed substantially rectangular.
A rope support surface portion 31B is continuously provided at an end portion on the door opening direction side of the main surface portion 31A, that is, an end portion disposed at a position away from the door pocket side end portion 11B of the second car side door 11B of the first car side door 11A. Hereinafter, the door opening direction of the first car side door 11A is referred to as the door pocket side, and the door closing direction of the first car side door 11A is referred to as the door stop side.
The rope support surface portion 31b protrudes downward in the vertical direction from the end portion of the main surface portion 31A on the jacket side, that is, from the first door hanger 21A toward the first car side door 11A. The rope support surface portion 31b is attached to the door pocket side end portion 11b of the first car side door 11A. The rope support surface portion 31b is formed by bending the door pocket side end substantially perpendicularly toward the elevator hall side. That is, the rope support surface portion 31b is formed in an L-shape in cross section taken in a horizontal direction orthogonal to the vertical direction. By forming the rope support surface portion 31b in an L shape in this way, the rigidity of the rope support surface portion 31b can be improved.
Further, a pair of first link members 41A, 41B are disposed at the door stop side end portion of the main surface portion 31A. The lower first link member 41A is disposed at a lower end portion in the vertical direction of the main surface portion 31A, and the upper first link member 41B is disposed at an upper end portion in the vertical direction of the main surface portion 31A. The lower first link member 41A and the upper first link member 41B are rotatably supported by the main surface portion 31A via the link shafts 42, respectively.
The shaft portions 43 are provided at the ends of the pair of first link members 41A and 41B opposite to the link shaft 42, respectively. The first car-side engaging piece 32 is attached to the shaft portions 43 of the pair of first link members 41A, 41B. Therefore, the first car-side engaging piece 32 is movably supported by the main surface portion 31A via the pair of first link members 41A and 41B.
The first car-side engaging piece 32 is formed of an elongated member extending in the vertical direction by a predetermined length. A power transmission portion 36 is provided at an intermediate portion in the longitudinal direction of the first car-side engaging piece 32. The transmission portion 36 is provided at the end portion of the first car-side engaging piece 32 on the door pocket side. The transmission portion 36 is in contact with a transmission pin 37 described later.
Further, a first stopper 45 fixed to the main surface portion 31A is disposed near the lower first link member 41A. When the car-side lock mechanism 30 is in the locked state, the first stopper 45 abuts against the door pocket side of the lower first link member 41A. Therefore, the counterclockwise rotation of the lower first link member 41A in fig. 3 is restricted by the first stopper 45.
A plurality of second stoppers 46 fixed to the main surface portion 31a are disposed on the door stop side of the first car-side engaging piece 32. When the car-side lock mechanism 30 is in the locked state, the second stopper 46 is disposed at a predetermined interval from the first car-side engaging piece 32. When the pair of first link members 41A and 41B rotate and the first car side engaging piece 32 moves toward the door stop side, the first car side engaging piece 32 abuts against the second stopper 46 (see fig. 6). Thus, the movement of the first car-side engaging piece 32 and the pair of first link members 41A and 41B is restricted by the second stopper 46.
The rotating shaft 35 is disposed closer to the door pocket side of the main surface portion 31a than the first car-side engaging piece 32 attached to the main surface portion 31 a. The upper lock hook member 33 is rotatably supported by the rotating shaft 35.
The locking side hook member 33 includes: a hook portion 33a, a rotation receiving portion 33b, a connecting portion 33c, and an unlock receiving portion 33 d. The rotation receiving portion 33b is rotatably supported by the rotation shaft 35. A transmission pin 37 is disposed below the pivot receiving portion 33b in the vertical direction with respect to the rotating shaft 35 and on the door stop side.
The transmission pin 37 contacts the transmission portion 36 provided in the first car-side engaging piece 32. When the first car side engaging piece 32 moves downward in the vertical direction and to the door stop side via the pair of first link members 41A, 41B, the operation of the first car side engaging piece 32 is transmitted to the transmission pin 37 via the transmission portion 36. Thereby, the locking side hook member 33 rotates counterclockwise (unlocking direction) in fig. 3 about the rotation shaft 35.
A connecting portion 33c is provided at the door stop side end of the pivot receiving portion 33 b. The connecting portion 33c protrudes from the pivot receiving portion 33b toward the door stop side. A hook portion 33a is formed at an end of the coupling portion 33c opposite to the rotation receiving portion 33 b. The hook portion 33a protrudes toward the door stop side of the first car-side engaging piece 32. When the car-side lock mechanism 30 is in the locked state, the hook portion 33a is disposed above the fixed hook member 34 in the vertical direction and engages with the fixed hook member 34 at a predetermined interval.
The unlock receiving portion 33d protrudes upward from the upper end portion in the vertical direction of the end portion of the pivot receiving portion 33b on the door pocket side. The unlock receiving portion 33d is disposed on the door pocket side of the rotating shaft 35 that supports the rotation receiving portion 33 b. The lock release receiving portion 33d engages with a lock release lever 54 described later. When the unlock receiving portion 33d is engaged with the unlock lever 54 and pulled to the door pocket side, the rotation receiving portion 33b rotates in the unlock direction.
The lock holding member 39 is disposed at the upper end portion in the vertical direction of the connecting portion 33c of the lock side hook member 33. The lock holding member 39 is disposed on the door stop side of the first car-side engaging piece 32. The locking holding member 39 biases the locking hook member 33 in the downward direction, i.e., in the locking direction, via the connecting portion 33 c.
A compression coil spring is applied as the locking and holding member 39 of this example. The locking holding member 39 is not limited to the compression coil spring, and various other elastic members such as a leaf spring and rubber may be used.
Further, a pair of second link members 61A, 61B are disposed at the end portion of the main surface portion 31A on the door pocket side. The lower second link member 61A is disposed at a lower end portion in the vertical direction of the main surface portion 31A, and the upper second link member 61B is disposed at an upper end portion in the vertical direction of the main surface portion 31A. The lower second link member 61A and the upper second link member 61B are rotatably supported by the main surface portion 31A via link shafts 62, respectively.
The shaft portions 63 are provided at the ends of the pair of second link members 61A, 61B opposite to the link shaft 62, respectively. The second car-side engaging piece 52 is attached to the shaft portions 63 of the pair of second link members 61A, 61B. Therefore, the second car-side engaging piece 52 is movably supported by the main surface portion 31A via the pair of second link members 61A, 61B.
The second car-side engaging piece 52 is formed of an elongated member extending in the vertical direction by a predetermined length. The second car side engaging piece 52 is disposed at the main surface portion 31a with a predetermined interval from the first car side engaging piece 32. The interval between the first car side engaging piece 32 and the second car side engaging piece 52 is set to be larger than the interval W1 of the hall side engaging pieces 235, 236 described later. Thus, the hall side engaging pieces 235, 236 can pass between the first car side engaging piece 32 and the second car side engaging piece 52 in the vertical direction.
Further, a third stopper 65 fixed to the main surface portion 31a is disposed below the upper second link member 61B in the vertical direction at an interval. When the upper second link member 61B is rotated clockwise, the third stopper 65 abuts against it (see fig. 7). Thereby, the turning operation of the upper second link member 61B is restricted, and the movement of the second car-side engaging piece 52 in the downward direction in the vertical direction is restricted.
Further, a fourth stopper 66 fixed to the main surface portion 31a is disposed on the door pocket side of the second car-side engaging piece 52 with a gap. When the pair of second link members 61A and 61B rotate and the second car side engaging piece 52 moves toward the door pocket side, the second car side engaging piece 52 abuts against the fourth stopper 66 (see fig. 10). Thus, the movement of the second car-side engaging piece 52 and the pair of second link members 61A, 61B is restricted by the fourth stopper 66.
Further, the upper end portion of the second car-side engaging piece 52 in the vertical direction protrudes upward in the vertical direction of the upper end portion of the first door hanger 21A. A rotatable cam roller 53 is attached to an upper end portion of the second car-side engaging piece 52. In a state where the pair of car side doors 11A, 11B are closed, the cam roller 53 abuts against a cam member 57 fixed to the car side door unit 12.
The cam member 57 is formed in a substantially arc shape, opens to the door opening direction side of the first car side door 11A, i.e., the door pocket side, and bends to the door stop side. The cam roller 53 abuts against the cam member 57, whereby the position of the second car side engaging piece 52 is maintained in the locked state shown in fig. 3. That is, the second car-side engaging piece 52 is held at a position where the upper second link member 61B does not abut against the third stopper 65 and the second car-side engaging piece 52 does not abut against the fourth stopper 66. When the cam roller 53 is separated from the cam member 57, the second car-side engaging piece 52 moves downward in the vertical direction due to its own weight (see fig. 7).
Further, an unlocking lever 54 is provided to the second car-side engaging piece 52. The lock release lever 54 is disposed between the cam roller 53 and the upper second link member 61B in the second car-side engaging piece 52. The lock release lever 54 protrudes from the second car-side engaging piece 52 toward the door stop side. The lock release lever 54 is disposed at a distance from the lock release receiving portion 33d and is engageable therewith. When the second car-side engaging piece 52 moves to the door pocket side, the unlocking lever 54 engages with the unlocking receiving portion 33d, and pulls the unlocking receiving portion 33d to the door pocket side (see fig. 10).
[ forced unlocking structure 70]
Next, the forced unlocking mechanism 70 includes: an unlocking rope 71, a direction switching member 72, and a plurality of guide members 73. One end 71a in the longitudinal direction of the unlocking cord 71 is disposed at the lower end in the vertical direction of the cord supporting surface portion 31 b. The plurality of guide members 73 are fixed to the rope support surface portion 31 b. The unlocking cord 71 is fixed to the cord support surface portion 31b by the plurality of guide members 71. Therefore, the unlocking rope 71 is disposed at the door pocket side end portion 11b of the first car side door 11A, and one end portion 71A thereof extends to the lower end portion in the vertical direction of the first car side door 11A.
Further, the other end portion 71b in the longitudinal direction of the unlocking rope 71 is connected to the second car-side engaging piece 52. Specifically, the other end portion 71b of the unlocking rope 71 is connected to the vicinity of the unlocking lever 54 of the second car-side engaging piece 52.
The direction conversion member 72 is disposed near the other end 71b of the unlocking cord 71 of the main surface portion 31 a. The direction switching member 72 has an unlocking rope 71 wound therearound. The direction switching member 72 switches the direction in which the unlocking rope 71 extends from the vertical direction to a direction inclined with respect to the opening and closing direction of the pair of car side doors 11A and 11B. The direction conversion member 72 can be, for example, a roller, a semicircular member, or the like.
[ side door Unit of Elevator hall and side door of Elevator hall ]
Next, the structure of the hall side door unit 212 will be described with reference to fig. 4 and 5. Fig. 4 is a front view of the doorway 102 viewed from the car 110 side.
As shown in fig. 4, the hall side door unit 212 includes: a hall side door guide rail 215, a first pulley 216, a second pulley 218, a belt 217, door hangers 221, and a hall side locking mechanism 230. The door hanger 221 is provided at the upper end of the elevator hall side door 211 in the vertical direction. A rotatable moving roller 224 is mounted on the door hanging plate 221. The movable roller 224 is slidably engaged with the hall side door rail 215. The hall side door guide rail 215 extends in the opening and closing direction of the pair of hall side doors 211, 211.
Further, the 2 door hanging plates 221 are provided with coupling members 222, 223, respectively. The coupling members 222, 223 are coupled with a transmission belt 217 described later. Further, of the 2 door hangers 221 and 221, the door hanger 221 facing the first door hanger 21A of the car 110 is provided with an elevator hall side lock mechanism 230. The hall-side locking mechanism 230 will be described later.
The first pulley 216 is disposed on one side of the elevator hall side door unit 212 in the horizontal direction, and the second pulley 218 is disposed on the other side of the elevator hall side door unit 212 in the horizontal direction. A belt 217 is wound around the first pulley 216 and the second pulley 218. The belt 217 is formed in an endless shape having both ends in the longitudinal direction connected to each other. Also, the upper and lower portions of the belt 217 in the up-down direction move in opposite directions to each other.
A first coupling member 222 is coupled to a lower portion, which is a return path side of the belt 217, and a second coupling member 223 is coupled to an upper portion, which is an forward path side of the belt 217. When the belt 217 moves, the pair of hall side doors 211, 211 move in a door closing direction in which they approach each other or in a door opening direction in which they separate from each other via the coupling members 222, 223.
[ Elevator hall side locking mechanism ]
Fig. 5 is a front view showing an elevator hall side locking mechanism 230. As shown in fig. 4 and 5, the hall-side locking mechanism 230 includes: an upper lock side hook member 231, a rotating shaft 232, 2 hall side engaging pieces 235, 236, a bottom plate 237, an upper lock holding member 239, and a stopper 241. The hall-side locking mechanism 230 includes a fixed hook member 234 (see fig. 4).
The bottom plate 237 is formed in a substantially flat plate shape. The bottom plate 237 is fixed to the door hanging plate 221. The fixed hook member 234 is fixed to a door hanger 221 or a hall side door 211 different from the door hanger 221 provided with the bottom plate 237.
The rotating shaft 232 and the second hall side engaging piece 236 are fixed to the bottom plate 237. A rotatable upper lock hook member 231 is provided on the rotation shaft 232. The locking side hook member 231 includes: a hook 231a engaged with the fixed hook member 234, a regulation piece 231b, and a bearing 231 c.
The restricting piece 231b is formed at an end opposite to the hook portion 231 a. Further, the upper end portion of the regulating piece 231b in the vertical direction abuts on the stopper 241 fixed to the bottom plate 237. Further, the stopper 241 abuts against the restriction piece 231b, thereby restricting the upper lock hook member 231 from rotating counterclockwise in fig. 5. A bearing 231c is provided between the regulating piece 231b and the hook 231 a.
The bearing 231c is rotatably supported by the rotating shaft 232. Further, a rotatable first hall side engaging piece 235 is attached to an upper end portion in the vertical direction of the bearing portion 231 c. The first hall side engaging piece 235 is disposed on the hook 231a side of the bearing 231 c. The first hall side engaging piece 235 and the second hall side engaging piece 236 are disposed so as to face each other in the opening/closing direction of the pair of hall side doors 211, 211. When the car 110 stops at any floor, the first hall side engaging piece 235 and the second hall side engaging piece 236 are disposed between the first car side engaging piece 32 and the second car side engaging piece 52.
Further, a lock holding member 239 is disposed near the first hall side engaging piece 235 of the upper lock side hook member 231. One end of the locking holding member 239 is fixed to the bottom plate 237, and the other end is fixed to the upper end portion of the locking side hook member 231 in the vertical direction. The locking holding member 239 urges the locking side hook member 231 downward in the upward locking direction, i.e., the vertical direction. Thereby, the locked state of the locking side hook member 231 in the hall side locking mechanism 230 is maintained.
The force with which the locking member 239 of the hall-side locking mechanism 230 is locked is set to be greater than the force with which the locking member 39 of the car-side locking mechanism 30 is locked. That is, the biasing force of the lock holding member 39 of the car-side locking mechanism 30 is set to be larger than the biasing force of the lock holding member 239 of the hall-side locking mechanism 230.
2. Door opening action of car side door and elevator hall side door
2-1 example of car stopping at the abutment area
Next, the door opening operation of the elevator 1 having the above-described configuration will be described with reference to fig. 2, 3, 6, and 7. First, an example in which the car 110 is stopped in the contact region where the car- side engaging pieces 32 and 52 and the hall- side engaging pieces 235 and 236 can be brought into contact will be described. Fig. 6 is a front view showing a state where the car-side lock mechanism 30 is unlocked, and fig. 7 is a front view showing a door opening operation of the car-side door.
As shown in fig. 2, when the car 110 stops at any floor, the car side door unit 12 faces the hall side door unit 212, and the car side lock mechanism 30 faces the hall side lock mechanism 230. As shown in fig. 3, a first hall side engaging piece 235 and a second hall side engaging piece 236 are inserted between the first car side engaging piece 32 and the second car side engaging piece 52.
In this state, when the driving portion 16 is driven and the pair of car side doors 11A and 11B move in the door opening direction away from each other, the first car side engaging piece 32 abuts against the first hall side engaging piece 235 as shown in fig. 6. When the first car side door 11A further moves in the door opening direction, the first car side engaging piece 32 is pressed by the first hall side engaging piece 235 in the direction opposite to the direction in which the first car side door 11A moves. Therefore, the pair of first link members 41A and 41B rotate about the link shaft 42, respectively. The first car-side engaging piece 32 moves in the direction opposite to the direction in which the first car-side door 11A moves, and also moves downward in the vertical direction.
The movement of the first car side engaging piece 32 is transmitted to the upper lock side hook member 33 via the transmission portion 36 and the transmission pin 37. Therefore, the locking side hook member 33 rotates about the rotating shaft 35 against the biasing force of the locking holding member 39. Then, the locking side hook member 33 is rotated upward in the vertical direction from the locking position where the hook portion 33a engages with the fixed hook member 34 to the unlocking position. Thereby, the engagement between the hook portion 33a and the fixed hook member 34 is released, and the car-side lock mechanism 30 is unlocked. Further, the first car side engaging piece 32 abuts against the second stopper 46, and the movement of the first car side engaging piece 32 is stopped.
As shown in fig. 7, when the first car side door 11A further moves in the door opening direction, the cam roller 53 provided in the second car side engaging piece 52 moves away from the cam member 57. Therefore, the second car-side engaging piece 52 moves downward in the vertical direction due to its own weight. Further, the pair of second link members 61A, 61B coupled to the second car-side engaging piece 52 rotate about the link shaft 62. Therefore, the second car side engaging piece 52 moves in a direction to approach the first car side engaging piece 32, that is, toward the door stop side. The second car-side engaging piece 52 abuts against the second hall-side engaging piece 236. Thereby, the two hall side engaging pieces 235, 236 are held by the first car side engaging piece 32 and the second car side engaging piece 52.
When the first car side door 11A moves in the door opening direction, the first hall side engaging piece 235 is pressed against the first car side engaging piece 32. The upper locking hook member 231 of the hall-side locking mechanism 230 rotates about the rotating shaft 232 against the biasing force of the upper locking member 239. Thereby, the elevator hall-side locking mechanism 230 is unlocked. As a result, the hall side doors 211, 211 move in the door opening direction together with the car side doors 11A, 11B, and the door opening operation of the car side doors 11A, 11B of the car 110 and the hall side doors 211, 211 of the hall 101 is completed.
When the first hall side engaging piece 235 and the second hall side engaging piece 236 are inserted between the first car side engaging piece 32 and the second car side engaging piece 52 at the time of a power failure, the operator can open the car side doors 11A and 11B by opening the hall side doors 211 and 211 with the hand. Specifically, the elevator hall side locking mechanism 230 is unlocked from the elevator hall 101 side using a jig. Then, the operator moves the hall side doors 211, 211 in the door opening direction by hand.
When the car side doors 211, 211 move in the door opening direction, the second hall side engaging piece 236 abuts against the second car side engaging piece 52. When the hall side doors 211, 211 are further moved in the door opening direction, the second car side engaging piece 52 is pressed by the second hall side engaging piece 236 in a direction away from the first car side engaging piece 32, that is, toward the door pocket side.
By pressing the second car-side engaging piece 52 toward the door pocket side, the pair of second link members 61A, 61B connected to the second car-side engaging piece 52 rotate about the link shaft 62. The cam roller 53 provided in the second car-side engaging piece 52 moves along the cam member 57. Therefore, the second car-side engaging piece 52 moves upward in the vertical direction.
When the second car side engaging piece 52 moves, the lock release lever 54 provided in the second car side engaging piece 52 also moves toward the door pocket side together with the second car side engaging piece 52. Therefore, the lock release lever 54 engages with the lock release receiving portion 33d, and pulls the lock release receiving portion 33d toward the door pocket. Thereby, the lock side hook member 33 rotates about the rotation shaft 35 in the unlocking direction in which the hook portion 33a is directed upward in the vertical direction against the biasing force of the lock holding member 39. As a result, the engagement between the hook portion 33a and the fixed hook member 34 is released, and the car-side lock mechanism 30 is unlocked. The operator can also move the car side doors 11A and 11B in the door opening direction by hand.
2-2 example of car stopping in non-abutting zone
Next, with reference to fig. 8 to 10, the unlocking operation of the car-side lock mechanism when the car- side engaging pieces 32 and 52 are brought into emergency stop in the non-contact area where the hall- side engaging pieces 235 and 236 cannot come into contact with each other will be described. Fig. 8 is an explanatory diagram showing an example of an unlocking operation of the car-side locking mechanism. In the example shown in fig. 8, the car side door sill 13 of the car 110 is stopped within a predetermined range T1 below the hall side door sill 213 in the vertical direction.
In the example shown in fig. 8, first, the hall-side locking mechanism 230 is unlocked from the hall 101 side using a jig, and the pair of hall side doors 211 and 211 are opened. Thereby, the car-side locking mechanism 30 is exposed to the doorway 102 of the car 110. The operator can then unlock the engagement between the locking hook member 33 and the fixed hook member 34 by grasping the locking hook member 33 and rotating it upward in the vertical direction.
Thus, the car-side locking mechanism 30 can be unlocked from outside the car room 10, not from inside the car room 10 of the car 110. As a result, it is confirmed that the passenger in the car 110 has safely left the elevator hall 101, and then the car-side locking mechanism 30 can be unlocked.
Fig. 9 and 10 are explanatory views showing another example of the unlocking operation of the car-side locking mechanism. In the example shown in fig. 9 and 10, the car side door sill 13 of the car 110 is stopped within a predetermined range T2 above the hall side door sill 213 in the vertical direction.
In the example shown in fig. 9 and 10, first, the hall-side locking mechanism 230 is unlocked from the hall 101 side using a jig, and a pair of hall side doors 211 and 211 are opened. As shown in fig. 9, the locking hook member 33 of the car-side locking mechanism 30 is located at a position that cannot be reached by a hand of an operator from the doorway 102 of the elevator hall 101.
However, as shown in fig. 9 and 10, the rope support surface portion 31b of the car-side locking mechanism 30 extends to the lower end portion in the vertical direction of the first car side door 11A. The unlocking rope 71 of the forced unlocking mechanism 70 is supported by the rope support surface portion 31b and extends to the lower end portion of the first car side door 11A. One end portion 71A of the unlocking rope 71 is disposed at the lower end portion of the first car side door 11A. Thus, even if the upper lock side hook member 33 is disposed at a position that cannot be reached by the operator with the hand from the doorway 102 of the elevator hall 101, the unlocking rope 71 can be caught from the doorway 102 of the elevator hall 101.
Then, the operator grasps the unlocking rope 71 and pulls it downward in the vertical direction. A direction switching member 72 for switching the extending direction thereof is disposed in the vicinity of the other end portion 71b of the unlocking cord 71. Therefore, by pulling the unlocking cord 71 downward in the vertical direction, the force applied to the unlocking cord 71 is converted from the downward direction in the vertical direction toward the door pocket side by the direction conversion member 72. Therefore, the other end portion 71b of the unlocking cord 71 is pulled toward the door pocket side.
The other end portion 71b of the unlocking rope 71 is pulled toward the door pocket side, and the second car-side engaging piece 52 to which the other end portion 71b is connected is pulled toward the door pocket side. Therefore, the pair of second link members 61A, 61B connected to the second car-side engaging piece 52 rotate about the link shaft 62, and the second car-side engaging piece 52 moves upward in the vertical direction while moving toward the door pocket side.
When the second car side engaging piece 52 moves, the lock release lever 54 provided in the second car side engaging piece 52 also moves toward the door pocket side together with the second car side engaging piece 52. Therefore, the lock release lever 54 engages with the lock release receiving portion 33d, and pulls the lock release receiving portion 33d toward the door pocket. Then, the lock side hook member 33 is rotated in the unlocking direction in which the hook portion 33a is directed upward in the vertical direction about the rotation shaft 35 against the biasing force of the lock holding member 39. Thereby, the engagement between the hook portion 33a and the fixed hook member 34 is released, and the car-side lock mechanism 30 is unlocked.
As a result, the car-side locking mechanism 30 can be easily unlocked from the outside of the car room 10, not from the inside of the car room 10 of the car 110, in the same manner as the operation shown in fig. 8.
According to the car-side locking mechanism 30 of the present example described above, the guide member 73 that supports the unlocking rope 71 of the forced unlocking mechanism 70 is fixed to the rope support surface portion 31b of the bottom plate 31. Therefore, not only a new elevator but also an existing elevator can be modified by providing the car-side locking mechanism 30 without opening a fixing hole for fixing the guide member 73 in the first car-side door 11A.
In the car-side locking mechanism 30 of the present example, the example in which the unlocking rope 71 is connected to the second car-side engaging piece 52 provided on the door pocket side has been described, but the present invention is not limited to this, and the unlocking rope 71 may be connected to the first car-side engaging piece 32 provided on the door stop side. Further, an example in which the rope support surface portion 31b is disposed at the door pocket side end portion 11b of the first car side door 11A and the one end portion 71A of the unlocking rope 71 is extended to the door pocket side end portion 11b of the first car side door 11A has been described, but the present invention is not limited thereto. For example, the rope support surface portion 31b and the one end portion 71A of the unlocking rope 71 may be disposed at the door stop side end portion 11A of the first car side door 11A.
However, other door devices such as the safety touch panel 25 and the detection portion are densely arranged on the door stop side end portion 11A of the first car side door 11A. Therefore, as in the car-side locking mechanism 30 of the present example, the unlocking rope 71 and the rope support surface portion 31b that supports the unlocking rope 71 are preferably disposed on the door pocket side end portion 11b of the first car-side door 11A. This prevents the unlocking rope 71 and the rope support surface portion 31b from interfering with other devices and the unlocking rope 71.
When the other end 71b of the unlocking rope 71 is connected to the first car-side engaging piece 32 and the one end 71A is disposed at the door pocket side end portion 11b of the first car side door 11A, the unlocking rope 71 passes through the intermediate portion 11c formed between the door pocket side end portion 11A and the door pocket side end portion 11 b. In this case, the hall-side engaging elements 235 and 236 may catch the unlocking rope 71. Therefore, as in the car-side locking mechanism 30 of the present example, it is preferable that the unlocking rope 71 is connected to the second car-side engaging piece 52 disposed on the door pocket side without passing through the intermediate portion 11c, and has one end portion 71a disposed on the door pocket-side end portion 11 b.
This prevents the hall side engaging pieces 235, 236 from catching the unlocking rope 71 when the hall side engaging pieces 235, 236 pass through the intermediate portion 11 c. Further, a window portion or the like can be provided in the intermediate portion 11c of the first car side door 11A, and the car 110 can be made aesthetically pleasing.
The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims.
In the above-described embodiment, the example in which the opening portion of the car room is opened and closed by moving the pair of door portions closer to and away from each other has been described, but the present invention is not limited to this, and the opening portion of the car room may be opened and closed by moving one door portion.
In the present specification, the terms "parallel" and "orthogonal" are used, but the terms "parallel" and "orthogonal" are not intended to mean only strictly "parallel" and "orthogonal", and include "parallel" and "orthogonal", and may be in a state of "substantially parallel" and "substantially orthogonal" within a range in which the functions thereof can be exhibited.
