Embodiment 1 FIG.
1 is a diagram showing an example of an elevator apparatus according to Embodiment 1 of the present invention. The elevator apparatus includes, for example, a car 1 and a counterweight 2. The car 1 moves up and down the hoistway 3. The counterweight 2 moves up and down the hoistway 3. The car 1 and the counterweight 2 are suspended from the hoistway 3 by the main rope 4. The roping method for suspending the car 1 and the counterweight 2 is not limited to the example shown in FIG.

  The main rope 4 is wound around the driving sheave 5 of the hoisting machine. The rotation and stop of the drive sheave 5 are controlled by the control device 6. FIG. 1 shows an example in which the control device 6 is provided in a machine room 7. The control device 6 may be provided in the hoistway 3. When the drive sheave 5 rotates, the main rope 4 moves in a direction corresponding to the rotation direction of the drive sheave 5. The car 1 is raised or lowered depending on the direction in which the main rope 4 moves. The counterweight 2 moves in the direction opposite to the direction in which the car 1 moves. The control device 6 stops the car 1 according to the height of the hall 8.

  FIG. 1 shows a state in which the car 1 is stopped at the landing 8 on the lowest floor. A landing door device 9 is provided at the landing 8 on each floor. A car door device 10 is provided in the car 1. The user moves between the landing 8 and the car 1 through the landing door device 9 and the car door device 10.

  FIG. 2 is a cross-sectional view of the landing door device 9 and the car door device 10. FIG. 2 shows a state where the car 1 is stopped at the landing 8. FIG. 3 is a view showing a cross section taken along the line AA of FIG. FIG. 4 is a view showing a BB cross section of FIG. 3. The landing door device 9 includes, for example, a landing door 11, a door hanger 12, a door roller 13, a door rail 14, a landing threshold 15, a door shoe 16, a roller 17, and an additional block 18.

The landing door 11 opens and closes the entrance / exit of the landing 8. The entrance / exit of the landing 8 is formed by, for example, a landing three-way frame and a floor of the landing 8. A door hanger 12 is provided on the landing door 11.
A door roller 13 is rotatably provided on the upper portion of the door hanger 12. The door roller 13 is placed on the door rail 14. Thereby, the landing door 11 is suspended from the door hanger 12. As the door roller 13 rolls on the door rail 14, the movement of the upper end portion of the landing door 11 is guided.

  The landing threshold 15 guides the movement of the landing door 11 together with the door rail 14. A landing threshold 15 is provided on the floor of the landing 8. A landing three-way frame is fixed to the landing threshold 15. The landing threshold 15 is arranged below the landing door 11. A guide groove 15 a is formed in the landing threshold 15 in a straight line. The door shoe 16 is provided at the lower end of the landing door 11. The door shoe 16 protrudes downward from the landing door 11. A part of the door shoe 16 is disposed in a guide groove 15 a formed in the landing threshold 15. As the door shoe 16 moves in the guide groove 15a, the movement of the lower end portion of the landing door 11 is guided.

  The car door device 10 includes, for example, a car door 19, a door hanger 20, a door roller 21, a door rail 22, a car sill 23, a door shoe 24, a driving device 25, a plate 26, an additional sill 27, and a sensor 28.

  The car door 19 opens and closes the entrance of the car 1. A door hanger 20 is provided on the upper portion of the car door 19. A door roller 21 is rotatably provided on the upper portion of the door hanger 20. The door roller 21 is placed on the door rail 22. As a result, the car door 19 is suspended from the door hanger 20. As the door roller 21 rolls on the door rail 22, the movement of the upper end portion of the car door 19 is guided.

  The car threshold 23 guides the movement of the car door 19 together with the door rail 22. The car sill 23 is provided on the floor of the car 1. The car sill 23 is arranged below the car door 19. In the car sill 23, guide grooves 23a are formed in a straight line. The door shoe 24 is provided at the lower end of the car door 19. The door shoe 24 protrudes downward from the car door 19. A part of the door shoe 24 is disposed in a guide groove 23 a formed in the car sill 23. When the door shoe 24 moves in the guide groove 23a, the movement of the lower end portion of the car door 19 is guided.

  The driving device 25 generates a driving force for moving the car door 19. That is, the car door 19 is driven by the driving device 25. The control device 6 controls the driving device 25, that is, opens and closes the car door 19. The landing door device 9 does not include a driving device for driving the landing door 11. The landing door 11 is driven by a driving device 25 provided in the car door device 10. In order to link the landing door 11 to the car door 19, the landing door device 9 is provided with a landing side interlocking device. Further, the car door device 10 is provided with a car-side interlocking device.

  The landing side interlocking device includes, for example, a roller 17. The roller 17 is provided on the landing door 11. The roller 17 protrudes from the back surface of the landing door 11. The car side interlocking device includes, for example, a pair of plates 26. The plate 26 is provided on the car door 19. The plate 26 protrudes from the back surface of the car door 19.

  As described above, FIG. 2 shows a state where the car 1 is stopped at the landing 8. When the car 1 stops at the landing 8, the roller 17 is disposed between the plates 26. When the car door 19 moves in the opening direction from this state, one plate 26 contacts the roller 17. Thereafter, when the car door 19 further moves in the opening direction, the roller 17 is pushed by the plate 26 and the landing door 11 moves in the opening direction. That is, the landing door 11 is opened in conjunction with the car door 19. Further, when the car door moves in the closing direction, the other plate 26 contacts the roller 17. When the roller 17 is further pressed against the plate 26 from this state, the landing door 11 is closed in conjunction with the car door 19.

  The edge of the landing sill 15 on the hoistway 3 side is straight. The edge of the car threshold 23 on the landing 8 side is straight. When the car 1 stops at the landing 8, a gap having a uniform width is formed between the landing threshold 15 and the cage threshold 23. For example, a gap with a width of about 30 mm is formed between the landing threshold 15 and the car threshold 23. The tip of the roller 17 is arranged at a position closer to the car 1 than the edge of the landing threshold 15. However, even if the car 1 moves, the roller 17 does not contact the car threshold 23. The tip of the plate 26 is disposed at a position closer to the landing 8 than the edge of the car sill 23. However, even if the car 1 moves, the plate 26 does not contact the landing threshold 15.

  The additional threshold 27 is for narrowing a gap formed between the landing threshold 15 and the cage threshold 23 when the car 1 stops at the landing 8. The additional sill 27 is provided in the car sill 23 along the edge of the car sill 23 on the landing 8 side, for example. The additional threshold 27 is arranged so that the upper surface thereof is flush with the upper surface of the car threshold 23. The additional threshold 27 is disposed between the landing threshold 15 and the cage threshold 23 when the car 1 stops at the landing 8. For example, when the car 1 stops at the landing 8, a gap having a width of about 10 mm is formed between the landing threshold 15 and the additional threshold 27.

  When the additional sill 27 is attached over the entire edge of the car sill 23 on the landing 8 side, the roller 17 contacts the additional sill 27 when the car 1 passes through the landing 8. For this reason, the additional sill 27 is attached to the car sill 23 so as not to be disposed immediately above and directly below the roller 17. A concave space when viewed from above is formed by the car sill 23 and the additional sill 27 in a portion through which the roller 17 passes. The additional block 18 is for filling a part of the concave space. The additional block 18 is provided on the landing threshold 15. When the car 1 stops at the landing 8, a part of the additional block 18 is disposed in the concave space. Note that the additional block 18 is not disposed directly above or directly below the plate 26. A part of the additional block 18 is disposed between the plates 26 when viewed from above.

  A slit 27 a is formed in the additional threshold 27. The slit 27a is formed in accordance with the position of the end face of the car door 19 when the car door 19 is closed. 3 and FIG. 4 is a center line L of the car 1. The car door device 10 according to the present embodiment includes a car door 19 of a center double opening type. That is, the center line L indicates the position of the end face of the car door 19 when the car door 19 is closed. The slit 27a is a gap having a width of about 10 mm, for example. It is desirable that the slit 27a has such a width that a human finger cannot easily enter. The slit 27a is formed, for example, so that the center line L passes through the center.

  The sensor 28 is for detecting that a string-like object is sandwiched between the car doors 19. Specifically, the sensor 28 detects foreign matter that has entered the slit 27 a of the additional threshold 27. The sensor 28 is provided on the additional threshold 27, for example. In the example shown in FIGS. 3 and 4, the sensor 28 is provided on the back surface of the additional threshold 27. A sensor 28 may be provided on the car sill 23.

  The sensor 28 includes a detector 29 for detecting that a foreign object (for example, a string-like object) has entered the slit 27a. 3 and 4 show an example in which the sensor 28 includes a rod-shaped detector 29. The detector 29 is disposed, for example, so as to cross the slit 27a below the slit 27a. The sensor 28 detects the presence of a foreign substance that has entered the slit 27a when the detector 29 is displaced downward.

  FIG. 5 is a diagram for explaining functions of the elevator apparatus according to Embodiment 1 of the present invention. FIG. 5 is a view corresponding to the CC cross section of FIG. 3. Consider a case where a pet and the pet owner get on the car 1 from the landing 8 and the pet gets off the car 1 just before the landing door 11 and the car door 19 are closed.

  The owner holds the lead 30 connected to the pet collar in the car 1. For this reason, when the landing door 11 and the car door 19 are closed, the lead 30 is sandwiched between the landing door 11 and the car door 19. In the car 1, for example, a beam sensor (not shown) is provided on a pillar that forms an entrance / exit. The car 1 is provided with a gate switch (not shown) for detecting that the car door 19 is completely closed. However, if the lead 30 is thin or the lead 30 is tape-like and thin, the beam sensor and the gate switch may not be able to detect the presence of the lead 30.

  When the gate switch detects that the car door 19 is completely closed, the control device 6 controls the hoist to move the car 1. FIG. 5 shows a state where the car 1 is raised while the lead 30 is sandwiched between the landing door 11 and the car door 19. When the car 1 rises, the lead 30 is stretched and the lead 30 enters the slit 27a. As a result, the lead 30 contacts the detector 29 of the sensor 28 from above, and the detector 29 is pushed downward by the lead 30. When the sensor 28 detects a foreign object as the detector 29 is displaced downward, the sensor 28 outputs a detection signal to the control device 6. When the control device 6 receives the detection signal from the sensor 28 while the car 1 is moving, the control device 6 stops the car 1.

  By providing the elevator device with the sensor 28, it is possible to prevent the car 1 from continuing to rise while a string-like object such as the lead 30 is sandwiched between the landing door 11 and the car door 19. The sensor 28 detects the presence of a foreign object using a slit 27a formed in the additional threshold 27. For this reason, the sensor 28 can be easily attached only by making a slight change to the car sill 23 such as forming a screw hole for fixing the additional sill 27. For example, when the sensor 28 is attached to an existing elevator device, the existing car sill 23 can be used as it is. This reduces the time and effort required for renovation work.

  FIG. 2 shows an example in which a sensor 32 such as a pressure sensor is provided on the upper frame 31 that forms the entrance / exit of the car 1. The sensor 32 is disposed at a position where the string-like object contacts when the car 1 descends while the string-like object such as the lead 30 is sandwiched between the landing door 11 and the car door 19. When the control device 6 receives a detection signal from the sensor 32 while the car 1 is moving, the control device 6 stops the car 1. Since the construction of the upper frame 31 is easier than the construction of replacing the landing threshold 15, the sensor 32 may detect the pinching of the string-like object when the car 1 is lowered.

  6, 7 and 8 are diagrams showing another example of the sensor 28 for detecting the foreign matter that has entered the slit 27a. FIG. 6 is a view corresponding to the AA cross section of FIG. 2. FIG. 7 is a view corresponding to the BB cross section of FIG. 3. FIG. 8 is a view corresponding to the CC cross section of FIG. 3. In the example illustrated in FIGS. 6 to 8, the sensor 28 includes, for example, a closing material 33, a link 34, and a detector 35.

  The closing material 33 is disposed in the slit 27a. The closing material 33 is disposed so as to close part or all of the slit 27a. 6 to 8 show examples in which the closing material 33 blocks a part of the slit 27a. For example, the upper surface of the closing material 33 is flush with the upper surface of the additional threshold 27. The closing material 33 is provided on the car sill 23. The closing material 33 may be provided on the additional threshold 27. For example, the end 33 a close to the car sill 23 is rotatably provided on the car sill 23 via the shaft 36. For this reason, the closing material 33 rotates around the end portion 33a, and the end portion 33b far from the car sill 23 is displaced up and down.

  The detector 35 detects the displacement of the closing material 33. In the example shown in FIGS. 6 to 8, the detector 35 is connected to the closing material 33 via the link 34. For this reason, when the plug 33 is pushed by a string-like object such as the lead 30 and the end portion 33b is displaced downward, the detector 35 is also displaced downward. The sensor 28 detects the presence of a foreign substance that has entered the slit 27a when the detector 35 is displaced downward.

  By using the sensor 28 shown in FIGS. 6 to 8, it is possible to detect the presence of the foreign matter that has entered the slit 27a earlier than in the case where the sensor 28 shown in FIGS. 3 to 5 is used. In addition, it is not essential to arrange the upper surface of the closing material 33 flush with the upper surface of the additional threshold 27. It is sufficient that at least a part of the closing material 33 is disposed in the slit 27a. However, when the height of the closing material 33 and the additional sill 27 does not match, there is a possibility that the user may feel uncomfortable. For this reason, it is desirable that the upper surface of the closing material 33 be arranged flush with the upper surface of the additional threshold 27. Even if the sensor 28 shown in FIGS. 6 to 8 is employed, the same effect as that obtained when the sensor 28 shown in FIGS. 3 to 5 is employed can be expected.

  9, FIG. 10 and FIG. 11 are diagrams showing another example of the sensor 28 for detecting the foreign matter entering the slit 27a. FIG. 9 is a diagram corresponding to the AA cross section of FIG. 2. FIG. 10 is a view corresponding to the BB cross section of FIG. FIG. 11 is a view corresponding to the CC cross section of FIG. 3. In the example shown in FIGS. 9 to 11, the sensor 28 includes, for example, a closing material 37, a light emitter 38 and a light receiver 39.

  The closing material 37 is disposed so as to close the slit 27a from below. The closing material 37 is disposed, for example, so as to cross the slit 27a below the slit 27a. For example, a part of the closing material 37 contacts the lower surface of the additional threshold 27. The closing material 37 is provided on the car sill 23. A blocking material 37 may be provided on the additional threshold 27. For example, the end 37 a close to the car sill 23 is rotatably provided on the car sill 23 via the shaft 40. For this reason, the closing material 37 rotates centering on the edge part 37a, and the edge part 37b far from the car sill 23 is displaced up and down.

  The light emitter 38 is provided on the closing material 37. For example, the light emitter 38 is provided on the lower surface of the closing material 37. The light receiver 39 is provided on the additional threshold 27. For example, the light receiver 39 is provided on the lower surface of the additional threshold 27. If the closing material 37 is in contact with the lower surface of the additional threshold 27, the light emitted from the light emitter 38 is received by the light receiver 39. When the closing member 37 is pushed by a string-like object such as the lead 30 and the end portion 37b is displaced downward, the light emitter 38 is also displaced downward. When the light emitter 38 is displaced downward, the light emitted from the light emitter 38 is not received by the light receiver 39. The sensor 28 detects the presence of foreign matter that has entered the slit 27a when the light receiver 39 stops receiving light from the light emitter 38.

  Even if the sensor 28 shown in FIGS. 9 to 11 is employed, the same effect as that obtained when the sensor 28 shown in FIGS. 3 to 5 is employed can be expected. The light receiver 39 may be provided on the closing material 37 and the light emitter 38 may be provided on the additional threshold 27. In this case, when the closing material 37 is pushed by a string-like object such as the lead 30 and the end portion 37b is displaced downward, the light receiver 39 is displaced downward. Even with such a configuration, the sensor 28 can detect the presence of a foreign substance that has entered the slit 27a.

  FIG. 12 is a diagram illustrating another example of the sensor 28 that detects a foreign substance that has entered the slit 27a. FIG. 12 is a view corresponding to the CC cross section of FIG. 3. In the example illustrated in FIG. 12, the sensor 28 includes, for example, a closing material 41, a light emitter 38, and a light receiver 39. The closing material 41 is different from the closing material 37 in that a part of the closing material 41 is disposed in the slit 27a. The other configuration of the closing material 41 is the same as that of the closing material 37. FIG. 12 shows an example in which the upper surface of the closing material 41 is arranged flush with the upper surface of the additional sill 27. It is not essential to arrange the upper surface of the closing material 41 flush with the upper surface of the additional threshold 27. However, in order not to give the user a sense of incongruity, it is desirable that the upper surface of the closing material 41 be arranged flush with the upper surface of the additional sill 27. Other configurations of the sensor 28 illustrated in FIG. 12 are the same as the configurations of the sensor 28 illustrated in FIGS. 9, 10, and 11.

Embodiment 2. FIG.
FIG. 13 shows an example of an elevator apparatus according to Embodiment 2 of the present invention. FIG. 13 is a diagram corresponding to the AA cross section of FIG. 2. The configuration of the elevator apparatus that is not disclosed in the present embodiment is the same as any configuration disclosed in the first embodiment. Note that the elevator apparatus in the present embodiment does not include the sensor 32.

  The landing door device 9 in the present embodiment includes, for example, an additional threshold 42 and a sensor 43 in addition to the landing door 11, the door hanger 12, the door roller 13, the door rail 14, the landing threshold 15, the door shoe 16 and the roller 17.

  The additional threshold 42 is for narrowing a gap formed between the landing threshold 15 and the cage threshold 23 when the car 1 stops at the landing 8. The additional sill 42 is provided on the landing sill 15 along, for example, the edge of the landing sill 15 on the hoistway 3 side. The additional threshold 42 is arranged so that the upper surface thereof is flush with the upper surface of the landing threshold 15. The additional threshold 42 is disposed between the landing threshold 15 and the cage threshold 23 when the car 1 stops at the landing 8. Specifically, the additional threshold 42 is disposed between the landing threshold 15 and the additional threshold 27 when the car 1 stops at the landing 8. For example, when the car 1 stops at the landing 8, a gap having a width of about 10 mm is formed between the additional threshold 27 and the additional threshold 42.

  As described above, a concave space as viewed from above is formed by the car sill 23 and the additional sill 27 in the portion through which the roller 17 passes. A part of the additional sill 42 protrudes so as to fill a part of the concave space. That is, the function of the additional block 18 provided in the landing door device 9 of the first embodiment is provided in the additional sill 42.

  A slit 42 a is formed in the additional threshold 42. The slit 42a is formed according to the position of the end surface of the landing door 11 when the landing door 11 is closed. The landing door device 9 in the present embodiment includes a center double opening type landing door 11. That is, the center line L indicates the position of the end face of the landing door 11 when the landing door 11 is closed. The slit 42a is a gap having a width of about 10 mm, for example. It is desirable that the slit 42a has such a width that a human finger cannot easily enter. The slit 42a is formed, for example, so that the center line L passes through the center.

  The sensor 43 is for detecting that a string-like object is sandwiched between the landing doors 11. Specifically, the sensor 43 detects foreign matter that has entered the slit 42 a of the additional threshold 42. The sensor 43 is provided on the additional threshold 42, for example. In the example shown in FIG. 13, the sensor 43 is provided on the back surface of the additional threshold 42. The sensor 43 may be provided on the landing threshold 15.

  The sensor 43 includes a detector 44 for detecting that a foreign object (for example, a string-like object) has entered the slit 42a. FIG. 13 shows an example in which the sensor 43 includes a rod-shaped detector 44. The detector 44 is disposed, for example, so as to cross the slit 42a below the slit 42a. The sensor 43 detects the presence of a foreign substance that has entered the slit 42a when the detector 44 is displaced downward.

  For example, consider a case where a pet and the pet owner get on the car 1 from the landing 8 and the pet gets off the car 1 just before the landing door 11 and the car door 19 are closed. When the landing door 11 and the car door 19 are closed, the lead 30 is sandwiched between the landing door 11 and the car door 19. When the gate switch detects that the car door 19 is completely closed, the control device 6 controls the hoist to move the car 1. When the car 1 is lowered, the lead 30 is stretched and the lead 30 enters the slit 42a. As a result, the lead 30 contacts the detector 44 of the sensor 43 from above, and the detector 44 is pushed downward by the lead 30. When the sensor 43 detects a foreign object as the detector 44 is displaced downward, the sensor 43 outputs a detection signal to the control device 6. When the control device 6 receives a detection signal from the sensor 43 while the car 1 is moving, the control device 6 stops the car 1.

  By including the sensor 43 in the elevator apparatus, it is possible to prevent the car 1 from continuing to descend while a string-like object such as the lead 30 is sandwiched between the landing door 11 and the car door 19. The sensor 43 detects the presence of a foreign object using a slit 42a formed in the additional threshold 42. For this reason, the sensor 43 can be easily attached only by making a slight change to the landing threshold 15 such as forming a screw hole for fixing the additional threshold 42. For example, even when the sensor 43 is attached to an existing elevator apparatus, the existing landing threshold 15 can be used as it is. This reduces the time and effort required for renovation work.

  The sensor 43 shown in FIG. 13 is an example. The sensor 43 may have the same configuration as the sensor 28 shown in FIGS. The sensor 43 may have the same configuration as the sensor 28 shown in FIGS. The sensor 43 may have the same configuration as the sensor 28 shown in FIG. Further, the additional sill 27 and the sensor 28 may be attached to the hall sill 15 without attaching the additional sill 27 and the sensor 28 to the car sill 23. In such a case, for example, a sensor similar to the sensor 32 may be installed on the upper frame of the landing three-way frame.
