The lower end portion of the panel portion 13 is detachably attached to the inner surface of the base plate 9 by the magnetic force of the magnet 15.

  In the viewpoint of FIG. 2, when the rotation shaft of the winding mechanism 16 rotates clockwise, the belt portion 14 moves in the pulling direction. That is, the portion of the belt portion 14 exposed inside the belt support member 12 is increased. In this case, the position of the lower end in the vertical direction of the panel unit 13 moves downward. On the other hand, in the viewpoint of FIG. 2, when the rotation shaft of the winding mechanism 16 rotates counterclockwise, the belt portion 14 moves in the winding direction. That is, the portion of the belt portion 14 exposed inside the belt support member 12 is reduced. In this case, the position of the lower end in the vertical direction of the panel unit 13 moves upward. Thus, by rotating the rotation shaft of the winding mechanism 16, the height adjustment of the baseboard 7 for a car is possible.

  FIG. 3 shows a state in which the rotation limiting device 17 is attached to the end of the winding mechanism 16. The rotation limiting device 17 is, for example, a bolt or the like. The rotation restricting device 17 fixes, for example, the rotation shaft of the winding mechanism 16 to the base plate 9. In the state in which the rotation limiting device 17 is attached to the winding mechanism 16, the rotation shaft can not rotate.

  FIG. 4 shows the handle 18 attached to the end of the winding mechanism 16. The handle 18 is attached to the rotation shaft of the winding mechanism 16 in a state where the rotation limiting device 17 is not attached. The rotation axis is rotated by the force applied through the handle 18.

  The end of the rotation shaft of the winding mechanism 16 shown in FIGS. 3 and 4 is exposed to the outside of the car 1. That is, the end of the rotating shaft is exposed not to the inside of the car 1 but to the internal space of the hoistway.

  FIG. 5 is a top view for explaining the height adjustment operation in the first embodiment. FIG. 6 is a side view for explaining the height adjustment operation in the first embodiment. 5 and 6 schematically show the position of the winding mechanism 16 inside the hoistway.

  As shown in FIGS. 5 and 6, the winding mechanism 16 is located between the side wall 4 of the car 1 and the hoistway wall 19. The handle 18 is attached to the rotation shaft of the winding mechanism 16 by, for example, a maintenance worker who has entered the interior of the hoistway. The maintenance worker adjusts the height of the baseboard 7 by turning the handle 18 inside the hoistway.

  In the first embodiment, the panel portion 13 is provided along the vertical direction below the wall of the elevator car 1 and above the floor 5 of the car 1. The belt portion 14 has one end connected to the upper end of the panel portion 13 and is wound around the winding mechanism 16. The winding mechanism 16 is attached to a baseboard 9 supported on at least one of the floor 5 or the wall of the car 1. For this reason, according to the first embodiment, the position of the lower end in the vertical direction of the base material 7 for a car can be easily changed by changing the amount by which the belt portion 14 is pulled out from the winding mechanism 16. Thereby, for example, when replacing the floor covering 11 in the car 1, the rotation shaft of the winding mechanism 16 may be rotated according to the thickness of the new floor covering 11. In other words, there is no need to replace or replace the car base according to the thickness of the floor covering. As a result, the work efficiency of the height adjustment of the car base can be improved.

  In the first embodiment, the winding mechanism 16 is located below the wall of the car 1 and outside the panel portion 13 above the floor 5 of the car 1. The belt portion 14 is folded downward below the wall of the car 1 and above the rotation axis of the winding mechanism 16 so that one end is exposed to the inside of the car 1. Therefore, according to the first embodiment, the baseboard 9, the fixing tool 10, the winding mechanism 16 and the like are not visually recognized from the inside of the car 1. Further, according to the first embodiment, the portion of the belt portion 14 exposed in the car 1 is apart from the floor 5. Thus, even if the elevator passenger looks down on the floor 5 in the car 1, the boundary between the panel portion 13 and the belt portion 14 is less noticeable. As a result, it is possible to prevent the appearance of the car from being impaired.

  In the first embodiment, the rotation shaft of the winding mechanism 16 rotates when a force is applied to the end exposed to the outside of the car 1. For this reason, according to Embodiment 1, the height adjustment of the basement 7 for a car can not be performed in the car 1. As a result, for example, it is possible to prevent a person who is not a maintenance worker from intentionally or unintentionally changing the height of the car base.

  In the first embodiment, the winding mechanism 16 is supported by a baseboard 9 provided between the wall of the car 1 and the floor 5 of the car 1. The panel portion 13 is attracted to the inner surface of the base plate 9 by the magnetic force. Therefore, according to the first embodiment, it is possible to prevent the displacement of the panel portion 13 in a state where the panel portion 13 can be easily attached and detached.

Second Embodiment
Hereinafter, the configuration of the winding-type elevator car baseboard will be described focusing on the difference from the first embodiment. The parts that are the same as or correspond to those in Embodiment 1 are given the same reference numerals, and part of the description will be omitted.

  FIG. 7 is a cross-sectional view showing an installation state of a car base according to the second embodiment. The left side in FIG. 7 is the inside, and the right side in FIG. 7 is the outside.

  As shown in FIG. 7, in the second embodiment, the belt support member 12 is not attached to the baseboard 9. The car base 7 includes a panel portion 13, a belt portion 14 and a shielding member 20. The winding direction of the belt portion 14 by the winding mechanism 16 is opposite to that in the first embodiment.

  The cross section of the shielding member 20 has, for example, an L shape. The shielding member 20 has, for example, a ceiling and a wall. The ceiling has, for example, a shape along the horizontal direction. The wall has, for example, a shape along the vertical direction. The ceiling portion of the shielding member 20 is fixed to the upper surface of the baseboard 9 by a fixing tool 10, for example. For example, the shielding member 20 may be detachably attached to the baseboard 9. The ceiling portion of the shielding member 20 projects, for example, inward of the inner surface of the baseboard 9. The wall of the shielding member 20 extends downward from the inner end of the ceiling. The wall portion of the shielding member 20 is located inside the panel portion 13. The lower end of the wall of the shielding member 20 is located below the rotation axis of the winding mechanism 16. The lower end of the wall of the shielding member 20 does not contact the baseboard 9.

  The shielding member 20 exhibits, for example, the same color or a similar color as the panel portion 13. The shielding member 20 is formed of, for example, the same material as the panel unit 13.

  The belt portion 14 is pulled downward as it hangs down from the inner end of the winding mechanism 16. The panel portion 13 passes downward through the gap between the lower end of the wall portion of the shielding member 20 and the base plate 9. The panel portion 13 is located between the wall portion of the shielding member 20 and the base plate 9 along the vertical direction. The belt portion 14 is not viewed from the inside of the car 1 unless the upper end of the panel portion 13 is positioned below the lower end of the wall portion of the shielding member 20.

  In the viewpoint of FIG. 7, when the rotation shaft of the winding mechanism 16 rotates counterclockwise, the belt portion 14 moves in the direction in which it is pulled out. In this case, the position of the lower end in the vertical direction of the panel unit 13 moves downward. On the other hand, when the rotation shaft of the winding mechanism 16 rotates clockwise in the viewpoint of FIG. 7, the belt portion 14 moves in the winding direction. In this case, the position of the lower end in the vertical direction of the panel unit 13 moves upward.

  In the second embodiment, the panel portion 13 is provided along the vertical direction below the wall of the elevator car 1 and above the floor 5 of the car 1. The belt portion 14 has one end connected to the upper end of the panel portion 13 and is wound around the winding mechanism 16. The winding mechanism 16 is attached to a baseboard 9 supported on at least one of the floor 5 or the wall of the car 1. For this reason, according to the second embodiment, as in the first embodiment, the work efficiency of the height adjustment of the car base can be improved.

  In the second embodiment, the shielding member 20 is supported by at least one of the floor 5 or the walls of the car 1, and has a wall along the vertical direction below the wall of the car 1 and above the floor 5 of the car 1. Have. The winding mechanism 16 is located outside the panel portion 13 below the wall of the car 1 and above the floor 5 of the car 1. The wall portion of the shielding member 20 is positioned inside the panel portion 13, and the lower end is positioned below the rotation axis of the winding mechanism 16. Therefore, according to the second embodiment, the upper part of the lower area of the wall of the car 1 and the upper area of the floor 5 of the car 1 is hidden by the wall of the shielding member 20. Thus, for example, the winding mechanism 16 and the like can be prevented from being viewed from the inside of the car 1 without folding the belt portion 14 downward above the rotation shaft of the winding mechanism 16. As a result, deterioration of the belt portion 14 can be suppressed.

  In the first and second embodiments, the winding mechanism 16 may be, for example, a mechanism that can pull out the belt portion 14 by pulling one end of the panel portion 13 or the belt portion 14 inside the car 1. In addition, the winding mechanism 16 may have a function of automatically winding the belt portion 14, for example. In this case, for example, when the floor covering 11 in the car 1 is replaced, the belt portion 14 may be pulled out toward the inside of the car 1 by the necessary amount after the new floor covering 11 is installed. As a result, the work efficiency of the height adjustment of the car base can be improved.
