  Hereinafter, embodiments of an elevator apparatus according to the present invention will be described in detail. In the following description, the car door is simply referred to as “door”, and the car door device is also simply referred to as “door device”.

  FIG. 1 is a rear view showing a car door device of an elevator apparatus according to an embodiment of the present invention, and is a view of the car door device seen from a hoistway side. The car door device includes a door device housing 2, a door rail 3, a pair of door main bodies 4, and a car sill 9.

  The door device housing 2 is fixed above the car entrance 1 where passengers get on and off and load and unload luggage. The door rail 3 is fixed to the door device housing 2 and extends along the opening direction of the car doorway 1. The pair of door main bodies 4 opens and closes the car doorway 1. Opening and closing of the door body 4 is guided by the door rail 3. The car sill 9 is fixed to the floor (car floor) of the car doorway 1.

  Each door body 4 includes a door panel 5, a door hanger 6, and a plurality of hanger rollers 7, and opens and closes the car doorway 1. The door hanger 6 is fixed to the upper end portion of the door panel 5. The plurality of hanger rollers 7 are provided on the door hanger 6 and roll along the door rail 3. The door panel 5 is suspended by the door hanger 6 and moves along the door rail 3 and the car sill 9. The door body 4 opens and closes when the door panel 5 is moved by a driving force of a door motor (not shown) mounted on the door device.

  When the car is loaded, the car floor sinks at the weight of the load. However, since the door panel 5 is suspended by the door hanger 6, the door panel 5 does not settle even when the car is loaded. For this reason, in the door-closed state, a gap is generated between the lower end of the door body 4 and the car sill 9 fixed to the car floor. In order to seal this gap, a door lower end sealing mechanism 8 is provided at the lower part of the door body 4.

  FIG. 2 is an enlarged view showing the lower part of the car door device, and shows the configuration of the door lower end sealing mechanism 8. 3 is a cross-sectional view of the car door device taken along line AA in FIG. FIG. 2 shows the door body 4 on the right side of the door body 4 shown in FIG. That is, a pair of door bodies 4 (not shown) exist on the left side of the door body 4 shown in FIG. FIG. 3 also shows a car 17 and a car floor 18. 2 and 3, the same reference numerals as those in FIG. 1 denote the same elements as those in FIG. 1, and description of these elements is omitted.

  A plurality of door legs 16 are attached to the lower end of each door body 4. The door leg 16 is fixed to a reinforcing member (not shown) fixed to the lower back of the door panel 5.

  The car sill 9 fixed to the car floor 18 is provided with a sill groove 9a. The sill groove 9a extends along the frontage direction of the car doorway 1 and has a door leg 16 inserted therein, which guides the lower end of the door body 4 when the door body 4 is opened and closed.

  The door lower end sealing mechanism 8 is provided at the lower part of the door panel 5 and includes a lower shield 14, a movable plate 12, and an interlocking mechanism 10.

  The lower shield 14 extends over the entire width of the door panel 5, is fixed to the movable plate 12, can move up and down together with the movable plate 12, descends when the door is closed, and when the door is closed, the door body The gap between the lower end of 4 and the car sill 9 is closed. The door panel 5 may be provided with a member (for example, a protruding portion) for guiding the vertical movement of the lower shield 14.

  Further, a seal member 15 that contacts the car sill 9 when the door is closed is provided at the lower end of the lower shield 14. The seal member 15 is made of, for example, an elastic body such as rubber or resin, and extends over the entire width direction of the door panel 5. As shown in FIG. 3, the seal member 15 abuts against the upper surface of the car sill 9 at a position between the sill groove 9 a and the car 17 when the door is closed, and the lower end of the door body 4 and the car sill 9 Seal the gap. When the door is open, the lower end of the seal member 15 is not in contact with the car sill 9 and is located above the car sill 9. The distance Lg between the lower end of the seal member 15 and the car sill 9 in the door open state when the car floor 18 is not settled can be arbitrarily determined.

  It is assumed that the seal member 15 has a vertical length longer than the maximum settling distance Ls of the car floor 18 due to loading. The maximum settling distance Ls of the car floor 18 due to loading can be obtained in advance based on the maximum loading capacity of the car. That is, the settling distance of the car floor 18 when the car load is maximum is the maximum settling distance Ls of the car floor 18. The gap between the lower end of the door body 4 and the car sill 9 is sealed using the seal member 15 having such a size.

  The movable plate 12 extends in the vertical direction, the lower shield 14 is fixed to the lower part, the upper part has a long hole 12a, and is connected to the interlocking mechanism 10 through the long hole 12a. When the movable plate 12 is lowered, the lower shield 14 is also lowered. The long hole 12a is a hole having a shape elongated in the vertical direction (see FIG. 4 described later). The length Lh in the vertical direction of the long hole 12a will be described later with reference to FIG.

  The interlocking mechanism 10 is supported by a roller 19 provided on the door panel 5 and is provided on the door panel 5. The interlocking mechanism 10 includes a vertical movement part 10 a and a horizontal movement part 10 b, a pressing part 11 at one end and a shaft at the other end. 13 is provided. The center of the roller 19 is fixed to the door panel 5 and is rotatable.

  The vertical movement part 10a is a part that moves in the vertical direction, and the horizontal movement part 10b is a part that moves in the horizontal direction. The vertical movement part 10a and the horizontal movement part 10b are not always fixed parts of the interlocking mechanism 10, but the two parts whose positions are separated by the roller 19 are named as the vertical movement part 10a and the horizontal movement part 10b for convenience. Is. That is, when the interlocking mechanism 10 moves with the rotation of the roller 19, a part of the vertical movement part 10a may become the left-right movement part 10b, and a part of the left-right movement part 10b may become the vertical movement part 10a. In the example shown in FIG. 2, when the left / right moving part 10b moves to the left, a part of the up / down moving part 10a becomes the left / right moving part 10b, and when the left / right moving part 10b moves to the right, A part becomes the vertical movement part 10a.

  The shaft 13 is provided in the vertical movement portion 10 a and is used for connection with the movable plate 12. The vertical length (thickness or width) of the shaft 13 is represented by d.

  The pressing part 11 is provided at one end of the left and right moving part 10b. When the door is open, the pressing part 11 is directed from the door body 4 provided with the interlocking mechanism 10 having the pressing part 11 toward the door body 4 to be paired. It protrudes. The protruding length (the length of the pressing portion 11) is the distance Lg between the lower end of the seal member 15 and the car sill 9 in the door open state when the car floor 18 is not settled and the maximum settling distance of the car floor 18. The sum of Ls, that is, Lg + Ls. When the door 11 is closed, the pressing portion 11 is pressed against the pressing portion 11 or the door panel 5 of the paired door main body 4 in the direction opposite to the direction in which the door main body 4 provided with the pressing portion 11 is closed. A specific configuration example of the interlocking mechanism 10 will be described later.

  The interlocking mechanism 10 also has a door lower end seal release mechanism 20 for moving the left-right moving part 10b in the direction opposite to the opening direction of the door body 4 provided with the interlocking mechanism 10 when the door is opened. Is provided. The door lower end seal release mechanism 20 always applies a weaker force to the left / right moving part 10b than the force by which the pressing part 11 is pressed in the direction opposite to the direction in which the pressing part 11 is pressed when the door is closed. Added. In the example shown in FIG. 2, the door lower end seal release mechanism 20 always applies a force from right to left with respect to the left and right moving portion 10b. Since the force which presses the press part 11 becomes weak at the time of a door opening, the left-right moving part 10b moves to the opposite direction at the time of a door closing by the effect | action of the door lower end part sealing cancellation | release mechanism 20. FIG. A specific configuration example of the door lower end seal release mechanism 20 will be described later.

  FIG. 4 is an enlarged view showing a connecting portion between the interlocking mechanism 10 and the movable plate 12. 4, the same reference numerals as those in FIGS. 1 to 3 denote the same elements as those in FIGS. 1 to 3, and the description of these elements will be omitted.

  As shown in FIG. 4, the shaft 13 of the interlocking mechanism 10 can pass through the inside of the long hole 12 a of the movable plate 12 so as to be movable up and down, and can be supported so as to hang the movable plate 12. The length Lh in the vertical direction of the long hole 12a is at least the sum of the maximum settling distance Ls of the car floor 18 and the length d in the vertical direction of the shaft 13, that is, at least Ls + d. In this embodiment, the length Lh in the vertical direction of the long hole 12a is Ls + d. Therefore, the shaft 13 can move up and down by the distance Ls inside the long hole 12a. When the vertically moving portion 10a moves downward, the movable plate 12 is lowered while being supported by the shaft 13 (while hanging). When the vertically moving portion 10a moves upward, the movable plate 12 rises as the shaft 13 pulls up the movable plate 12 from the inner upper portion of the long hole 12a.

  In the interlocking mechanism 10, when the pressing portion 11 is pressed when the door is closed, the left and right moving portion 10 b moves in a direction opposite to the closing direction of the door body 4, and the direction of this movement is changed by the roller 19. 10a moves downward, lowers the movable plate 12, and lowers the lower shield 14. In the example shown in FIG. 2, the door body 4 closes from right to left, so the pressing portion 11 is pressed in the right direction, and the left-right moving portion 10 b moves from left to right. The moving distance of the left and right moving part 10b when the door body 4 is completely closed, that is, the maximum moving distance of the left and right moving part 10b (equal to the maximum moving distance of the vertical moving part 10a) is the length of the pressing part 11. Equal to Lg + Ls.

  Further, when the door is opened, the interlocking mechanism 10 moves the left and right moving part 10b in the opposite direction to that when the door is closed by the door lower end seal release mechanism 20 (see FIG. 2), and the roller 19 changes the direction of this movement. As a result, the vertically moving portion 10a moves upward to raise the movable plate 12 and the lower shield 14. The movement distance of the interlocking mechanism 10 (the vertical movement part 10a and the horizontal movement part 10b) by the door lower end seal release mechanism 20 when the door is opened is Lg + Ls. In the example shown in FIG. 2, the left-right moving unit 10b moves from right to left.

  As described above, the interlocking mechanism 10 is a mechanism for lowering the movable plate 12 connected to the other end when the pressing portion 11 at one end is pressed when the door is closed, and such an operation is possible. If so, the shape and material can be arbitrarily determined. For the interlocking mechanism 10, for example, a rope-like cord-like body, a plate-like member, or a rod-like member can be used. When a rope-like cord-like body is used for the interlocking mechanism 10, the cord-like body is wound around the roller 19, and when one end portion (pressing portion 11) is pressed, the rope-like body is sent out by the rotation of the roller 19. The movable plate 12 is moved down. When a plate-like member or a rod-like member is used for the interlocking mechanism 10, the plate-like member or the rod-like member is fixed to the roller 19, and rotates with the roller 19 when one end (pressing portion 11) is pressed down. The movable plate 12 is moved down.

  As described above, the door lower end seal release mechanism 20 is applied to the left and right moving part 10b by a force that presses the pressing part 11 in a direction opposite to the direction in which the pressing part 11 is pressed when the door is closed. However, if such an operation is possible, the shape and material can be determined arbitrarily. For the door lower end seal release mechanism 20, for example, a weight or a spring can be used. When a cord-like body such as a rope is used for the interlocking mechanism 10, it is effective to use a weight as the door lower end seal release mechanism 20. Due to the weight of the weight fixed to the cord-like body, a force can be applied to the left and right moving portion 10b in the direction opposite to the direction in which the pressing portion 11 is pressed when the door is closed. When using a plate-like member or a rod-like member for the interlocking mechanism 10, it is effective to use a spring as the door lower end seal release mechanism 20. In the example shown in FIG. 2, a spring fixed to the door panel 5 and the roller 19 (more specifically, the protruding portion of the roller 19) is used as the door lower end seal release mechanism 20. By applying force in the rotational direction to the roller 19 by the elastic force of the spring (in FIG. 2, acting in the direction indicated by the arrow attached to the spring), the left and right moving portion 10b fixed to the roller 19 is applied. A force can be applied in the direction opposite to the direction in which the pressing portion 11 is pressed when the door is closed.

  Further, the door lower end seal release mechanism 20 adjusts the weight of the weight and the elastic force of the spring so that the left and right moving part 10b moves in a direction opposite to that when the door is closed by the distance Lg + Ls. Provide. A mechanism for suppressing the movement of the left and right moving part 10b so that the left and right moving part 10b does not move more than the distance Lg + Ls may be provided in the door lower end seal release mechanism 20 and the interlocking mechanism 10.

  Next, the operation of the door lower end portion sealing mechanism 8 when the door is closed when the car floor 18 is settled or not when loaded is described with reference to FIGS. 5A to 5B and FIGS. 6A to 6C. explain. 5A to 5B and FIGS. 6A to 6C, the same reference numerals as those in FIGS. 1 to 4 indicate the same elements as those in FIGS. 1 to 4, and the description of these elements is omitted. 5A to 5B and FIGS. 6A to 6C, one door panel 5 of the pair of door main bodies 4, the interlocking mechanism 10 (vertical moving portion 10 a), the movable plate 12, the lower shielding body 14, the seal member 15, and the car The threshold 9 is enlarged and some of these are shown. For ease of explanation, in FIGS. 5A to 5B, the car sill 9 is the largest of the car floor 18 together with the car floor 18 (not shown in FIGS. 5A to 5B and FIGS. 6A to 6C). 5A to 5B and FIGS. 6A to 6C, the distance between the lower end of the seal member 15 and the car sill 9 when the car floor 18 is not settled is assumed. Lg and the settling distance Ls of the car sill 9 are greatly exaggerated.

  When the door closing operation of the door body 4 is started, the pressing portion 11 (see FIG. 2) is pressed, so that the vertical movement portion 10a of the interlocking mechanism 10 moves downward, and the movable plate 12 moves to the shaft 13. It descends while being supported. When the movable plate 12 is lowered, the lower shield 14 is lowered, and the seal member 15 fixed to the lower shield 14 is also lowered.

  5A and 5B are partial enlarged views of the door body 4 when the car floor 18 is settling due to loading, and are diagrams illustrating the operation of the door lower end sealing mechanism 8 when the door is closed.

  FIG. 5A shows the door open state. Since the car sill 9 sinks by the distance Ls, the distance between the lower end of the seal member 15 and the car sill 9 is Lg + Ls. Although not shown in FIG. 5A, the pressing portion 11 protrudes from the door body 4 by the length of Lg + Ls as described above.

  As the door body 4 closes, the pressing portion 11 is pressed, and the vertical movement portion 10a, the movable plate 12, the lower shielding body 14, and the seal member 15 are lowered. As described above, the moving distance of the vertically moving portion 10a when the door body 4 is completely closed is equal to the length Lg + Ls of the pressing portion 11. Therefore, when the door main body 4 is completely closed, the seal member 15 comes into contact with the upper surface of the car sill 9 and seals the gap between the lower end of the door main body 4 and the car sill 9.

  FIG. 5B shows a state when the door body 4 is completely closed. Since the vertically moving portion 10a is lowered by the distance Lg + Ls between the lower end of the seal member 15 and the car sill 9, the movable plate 12 is lowered by the distance Lg + Ls while being supported (hanging) by the shaft 13. As a result, the lower shield 14 is also lowered by the distance Lg + Ls, and the seal member 15 is in contact with the upper surface of the car sill 9 and seals the gap between the lower end of the door body 4 and the car sill 9. At this time, the shaft 13 is in contact with the upper end of the long hole 12a.

  When the car floor 18 is not settling most, that is, when the car threshold 9 is settling by a distance Ls ′ that is smaller than the distance Ls, the sealing member is the same as in the case where the car floor 18 is not settling later. After 15 abuts on the upper surface of the car sill 9, the shaft 13 moves downward inside the long hole 12 a, so that the vertical movement portion 10 a can be further lowered and the door body 4 can be completely closed. it can. In a state where the door body 4 is completely closed, the shaft 13 is located in any one of the long holes 12a according to the distance Ls ′ in which the car sill 9 sinks (specifically, the shaft 13 is The inside of the long hole 12a is moved downward by a distance Ls-Ls ', and the upper end of the shaft 13 is located at a position away from the upper end of the long hole 12a by a distance Ls-Ls').

  6A to 6C are partial enlarged views of the door body 4 when the car floor 18 is not settled due to loading, and are diagrams illustrating the operation of the door lower end sealing mechanism 8 when the door is closed.

  FIG. 6A shows the door open state. Since the car sill 9 does not sink, the distance between the lower end of the seal member 15 and the car sill 9 is Lg. Although not shown in FIG. 6A, the pressing portion 11 protrudes from the door body 4 by the length of Lg + Ls as described above.

  As the door body 4 closes, the pressing portion 11 is pressed, and the vertical movement portion 10a, the movable plate 12, the lower shielding body 14, and the seal member 15 are lowered. When the door body 4 is closed by the distance Lg and the vertically moving portion 10a and the movable plate 12 are lowered by the distance Lg, the seal member 15 comes into contact with the upper surface of the car sill 9, and the lower end of the door main body 4 and the car sill 9 Seal the gap.

  FIG. 6B shows a state when the vertical movement portion 10a and the movable plate 12 are lowered by a distance Lg. Since the vertically moving portion 10a is lowered by the distance Lg, the movable plate 12 is lowered by the distance Lg while being supported by the shaft 13 (while hanging). As a result, the lower shield 14 is also lowered by the distance Lg, and the seal member 15 is in contact with the upper surface of the car sill 9 and seals the gap between the lower end of the door body 4 and the car sill 9. At this time, the shaft 13 is in contact with the upper end of the long hole 12a.

  In the state shown in FIG. 6B, since the seal member 15 is in contact with the upper surface of the car sill 9, the movable plate 12 cannot be lowered any further. However, although not shown in FIG. 6B, the pressing portion 11 protrudes from the door body 4 by a length Ls, and the door body 4 is not completely closed.

  When the door body 4 is further closed and the pressing portion 11 is pressed, the movable plate 12 does not descend, but the vertical movement portion 10a can descend by the distance Ls. The reason for this is that, as shown in FIG. 4, the length Lh in the vertical direction of the long hole 12a is Ls + d, and the shaft 13 can move downward within the long hole 12a by a distance Ls. . In this way, the door body 4 can be completely closed.

  FIG. 6C shows a state when the door body 4 is completely closed. Since the vertical movement portion 10a is further lowered by the distance Ls from the state of FIG. 6B, the shaft 13 is in contact with the lower end of the long hole 12a.

  Next, the operation of the door lower end portion sealing mechanism 8 when the door is opened when the car floor 18 is settled or not when loaded will be described. When the door opening operation of the door main body 4 is started, the pressing portion 11 is not pressed, and the vertical movement portion 10a moves upward. When the door body 4 is completely opened, the vertical movement portion 10a is raised by a distance Lg + Ls.

  When the car floor 18 is settling due to loading and the car floor 18 is settling most, that is, when the car sill 9 is settling by the distance Ls, the shaft 13 is as shown in FIG. 5B. It is in contact with the upper end of the long hole 12a. In this case, the shaft 13 pulls up the movable plate 12 by the distance Lg + Ls from the inner upper part of the long hole 12a when the vertical movement portion 10a rises by the distance Lg + Ls.

  When the car floor 18 is settling due to loading and the car floor 18 is not settling most, that is, when the car sill 9 is settling by a distance Ls ′ (<Ls), the upper end of the shaft 13 is It is located at a location separated from the upper end of the long hole 12a by a distance Ls-Ls ′. In this case, when the vertical movement portion 10a is lifted by the distance Ls−Ls ′, the shaft 13 also moves up the interior of the long hole 12a by the distance Ls−Ls ′ and contacts the upper end of the long hole 12a. . When the vertically moving portion 10a further rises by a distance Ls '+ Lg, the shaft 13 pulls up the movable plate 12 from the inner upper part of the long hole 12a by a distance Ls' + Lg. As a result, when the door body 4 is completely opened (when the vertical movement portion 10a is raised by the distance Lg + Ls), the state shown in FIG. 5A is obtained.

  When the car floor 18 does not sink due to the loading, the shaft 13 is in contact with the lower end of the long hole 12a as shown in FIG. 6C. In this case, when the vertical movement portion 10a is lifted by the distance Ls, the shaft 13 also moves up the distance Ls in the long hole 12a and contacts the upper end of the long hole 12a. When the vertically moving portion 10a further rises by the distance Lg, the shaft 13 pulls up the movable plate 12 by the distance Lg from the upper part inside the elongated hole 12a. As a result, when the door body 4 is completely opened, the state shown in FIG. 6A is obtained.

  In this way, the vertically moving portion 10 a raises the movable plate 12 and the lower shield 14 and separates the seal member 15 from the car sill 9. Therefore, the door opening operation of the door body 4 is performed in a state where the seal member 15 is separated from the car sill 9.

  As described above, in the elevator apparatus according to the present embodiment, the interlocking mechanism 10 (vertical moving portion 10a) and the movable plate 12 can change the relative positions in the vertical direction by the shaft 13 and the long hole 12a. Regardless of whether the car floor 18 (the car sill 9) sinks or not, the gap between the lower end of the door body 4 and the car sill 9 can be reliably sealed in the door-closed state. Since the door opening operation of the door body 4 is performed without contact between the seal member 15 and the car sill 9, the opening / closing operation performance of the door body 4 can be maintained. Therefore, in the elevator apparatus according to the present embodiment, the air tightness, smoke insulation, sound insulation, and light shielding can be improved.

  In addition, this invention is not limited to said Example, Various modifications are included. For example, the above-described embodiments are described in detail for easy understanding of the present invention, and the present invention is not necessarily limited to an aspect including all the configurations described.

  Further, in each drawing, control lines and information lines are described as necessary for explanation, and not all control lines and information lines necessary as products are necessarily described. In an actual product, it may be considered that almost all components are connected to each other.
