The design surface of the car floor 16 is a surface of the car floor 16 exposed in the car room 13.

Next, an operation for updating the design surface of the car floor 16 configured as described above will be described.
First, as shown in FIG. 8, the skirting board 38 is removed from the skirting board support portion 22, and the stopper 35 is removed from the floor main body portion 18. Then, the hanging portion 35b of the stopper 35 is inserted into the hanging hole 30b opened at the edge of the first floor panel 26A. Then, the displacement regulating portion 35a is gripped with pliers or the like, and the first floor panel 26A is pulled together with the displacement regulating portion 35a against the magnetic force acting in the direction in which the first floor panel 26A is attracted to the floor main body portion 18, The one floor panel 26 </ b> A is removed from the floor main body 18. At this time, even the first floor panel 26 </ b> A located in the vicinity of the skirting board support portion 22 can be easily detached from the floor main body portion 18 without being disturbed by the skirting board support portion 22. The removed first floor panel 26 </ b> A is leaned against the car side wall 40.

  Next, the remaining first floor panel 26A is removed. Further, the second floor panel 26 </ b> B is pulled against the magnetic force acting in the direction in which the second floor panel 26 </ b> B is attracted to the floor body 18, and the second floor panel 26 </ b> B is removed from the floor body 18. At this time, since the second floor panel 26B is located on the center side of the laying surface 18a, the second floor panel 26B is not obstructed by the skirting board support portion 22 and can be easily detached from the floor main body portion 18 without using pliers or the like. The removed first floor panel 26 </ b> A and second floor panel 26 </ b> B are then stood against the car side wall 40. The order of removing the remaining first floor panel 26A and second floor panel 26B is not particularly defined.

  Then, the removed first floor panel 26A and second floor panel 26B are laid again at the original position of the laying surface 18a with the second panel plates 28b and 28d facing upward. As a result, the first floor panel 26A and the second floor panel 26B are turned over and placed on the laying surface 18a, so that the design surface of the car floor 16 is updated.

  Then, the tip of the shift restricting portion 35a of the stopper 35 is inserted into the slit 19 to prevent the laying panel group 25 from being displaced, and the skirting board 38 is supported by the skirting board support section 22, thereby Work related to the renewal of the design surface is completed.

  When the design surface of the car floor 16 is updated with the new first floor panel and the second floor panel in place of the existing first floor panel 26A and the second floor panel 26B, first, the removed first floor panel 26A is removed. And the second floor panel 26 </ b> B is removed to the outside of the cab 13. And a new 1st floor panel and a 2nd floor panel are spread | laid on the laying surface 18a similarly to the existing 1st floor panel 26A and the 2nd floor panel 26B. Then, the stopper 35 is inserted into the slit 19 to prevent the laying panel group 25 from being displaced, and the skirting board 38 is supported by the skirting board support portion 22 so that the design surface of the car floor 16 can be updated. Is completed.

  According to the car 11 of the elevator 1 of this embodiment, the car floor 16 is provided with the steel material 17 having the laying surface 18a on the upper surface, and the first floor panel 26A and the second floor panel 26B on which the permanent magnets 27 are mounted. And a laying panel group 25 laid on the surface 18a.

Thereby, the first floor panel 26A and the second floor panel 26B are attracted to the steel material 17 by the magnetic force generated by each of the first floor panel 26A and the second floor panel 26B, and the first floor panel 26A and the second floor panel 26B are drawn. The floor panel 26 </ b> B can be stably held at a predetermined position of the laying surface 18 a of the steel material 17 and can be easily attached to and detached from the steel material 17.
That is, since the first floor panel 26A and the second floor panel 26B can be laid on the laying surface 18a without using an adhesive, there is no need to wipe off the adhesive, and the first floor panel 26A and the first floor panel 26A can be removed. The working efficiency is improved when the laying panel group 25 is configured by laying the two floor panels 26B on the laying surface 18a.

Further, the first floor panel 26A is configured by interposing a permanent magnet 27 integrally between the other surfaces of the first panel plate 28a and the second panel plate 28b (a pair of panel plates) having one surface as a design surface, The second floor panel 26B is configured by interposing a permanent magnet 27 integrally between the other surfaces of the first panel plate 28c and the second panel plate 28d (a pair of panel plates) having one surface as a design surface.
That is, since the first floor panel 26A and the second floor panel 26B have design surfaces on both sides, the cage floor can be obtained simply by turning the removed first floor panel 26A and the second floor panel 26B over and laying them again on the laying surface 18a. Sixteen design surfaces can be updated.

  In addition, when the design surface of the car floor 16 is updated by turning the first floor panel 26A and the second floor panel 26B upside down, the existing first floor panel 26A and the second floor panel 26B are replaced with the new first floor panel and the second floor panel 26B. In any case where the two floor panels are replaced, the work time required to remove the first floor panel 26A and the second floor panel 26B is shortened, so the first floor panel 26A and the second floor panel 26B are turned over. Or the cost of replacing them can be reduced. That is, the cost for updating the design surface of the car floor 16 can be reduced.

Furthermore, since the first floor panel 26A and the second floor panel 26B can be easily detached from the steel material 17, when the design surface of the car floor 16 deteriorates in appearance or is damaged, the car floor can be quickly obtained. 16 design surfaces can be updated.
Moreover, since the cost required for renewing the design surface of the car floor 16 can be reduced and the first floor panel 26A and the second floor panel 26B can be easily removed, the design surface of the car floor 16 is left unsatisfactory. Users will not feel uncomfortable.

  Furthermore, since the stopper 35 for restricting the sliding movement of the laying panel group 25 is attached to the steel material 17, the displacement of the laying surface 18a of the laying panel group 25 from a predetermined position can be prevented more reliably.

  The first floor panel 26 </ b> A constituting the edge of the laying panel group 25 is formed with hanging holes 30 a and 30 b that open to the side surfaces. The first floor panel 26A can be easily placed on the floor without being obstructed by the skirting board support portion 22 by hooking the hook portion 35b of the stopper 35 on the hook holes 30a and 30b and pulling the displacement restricting portion 35a with pliers or the like. It can be removed from the main body 18.

In this embodiment, each of the first floor panel 26A and the second floor panel 26B is configured by integrating a permanent magnet 27 between the other surfaces of a pair of panel plates having one surface as a design surface. explained.
However, each of the first floor panel and the second floor panel may be configured by integrally mounting the permanent magnet 27 on the other surface of the panel plate having one surface as a design surface.
In this case, only one surface of the first floor panel and the second floor panel is used as a design surface of the car floor 16, but the first floor panel and the second floor panel can be easily detached from the floor main body portion 18. The effect is not impaired.

However, when both surfaces of the floor panel are used as design surfaces like the first floor panel 26A and the second floor panel 26B, the first floor panel 26A and the second floor panel 26B are brought into the cab 13 by 2 Only one update of the design surface of the car floor 16 is required. Thus, the car floor 16 configured using the first floor panel 26A and the second floor panel 26B has the same frequency as compared to the case where the car floor is configured using a floor panel that uses only one surface as a design surface. The cost for transporting the first floor panel 26A and the second floor panel 26B when the design surface of the car floor 16 is continuously updated can be reduced.
Furthermore, when using both sides of a floor panel as a design surface, such as the first floor panel 26A and the second floor panel 26B, compared to a car floor configured using a floor panel that uses only one surface as a design surface, the same frequency It is possible to reduce the amount of floor panel disposal when the design surface of the car floor 16 is continuously updated.

  Moreover, although the stopper 35 was demonstrated as what is mounted | worn with the site | part of the floor main-body part 18 near the outer edge of the laying panel group 25, the magnetic force of the permanent magnet 27 is enough, and the laying panel group 25 follows the laying surface 18a. If there is no fear of sliding, the mounting of the stopper 35 may be omitted.

  In addition, the first floor panel 26A has been described as constituting the hanging holes 30a and 30b. However, if the first floor panel 26A can be removed from the floor body 18 without using the hanging holes 30a and 30b, the first floor panel 26A is hung. The holes 30a and 30b may be omitted. That is, the second floor panel 26B may be used instead of the first floor panel 26A.

  In addition, the permanent magnet 27, the first panel plates 28a and 28c, and the second panel plates 28b and 28d have been described as having the same main surface area, but the permanent magnets are the first panel plates 28a and 28c and the second panel plates 28a and 28d. You may use what has the area of the main surface smaller than the area of the main surface of the panel boards 28b and 28d. However, it is a condition that the first floor panel and the second floor panel can be stably held on the floor body 18 by the magnetic force of the permanent magnet.

  The hanging holes 30a and 30b are constituted by grooves 29a and 29b and permanent magnets 27 formed in the first panel plate 28a and the second panel plate 28b of the first floor panel 26A constituting the laying panel group 25. As described above, the hooking hole may be formed so as to open to at least one of the side surfaces of the first panel plate 28 a, the second panel plate 28 b, and the permanent magnet 27. That is, the hanging hole may not be configured by the cooperation of the grooves 29 a and 29 b of the first panel plate 28 a and the second panel plate 28 b and the permanent magnet 27, and the first hole that constitutes the edge of the laying panel group 25. What is necessary is just to be formed so that it may open to the side surface of the floor panel 26A.

Further, the laying panel group 25 is described as a structure in which a square floor panel 26A (26B) formed by sticking square panel plates 28a, 28c (28b, 28d) to a permanent magnet 27 is laid on the laying surface 18a. However, the laying panel group is not limited to a configuration in which a square floor panel is laid on the laying surface 18a, but is configured by laying floor panels of other shapes such as a rectangle, a triangle, and a pentagon on the laying surface 18a. Also good.
Further, the laying panel group is not limited to the one configured by laying floor panels having the same shape. For example, the laying panel group may be configured by laying a concave floor panel and a convex floor panel on the laying surface 18a while fitting the concave and convex portions.
