There is a car sill 6 on the front side of the car floor frame 1, that is, the part facing the landing on the lower side of the part provided with the door of the car. Further, the car sill 7 is further attached to the front of the car sill 6 and the part facing the platform of the car sill 6.

  The details of the car sill part in the aluminum material specification are as shown in FIGS. An aluminum material car sill support 12 is fixed to the car floor frame with bolts, and an aluminum material car sill support 12 and an aluminum material car sill support 11 are also fixed with bolts. The sill 13 added to the aluminum sill sill is fixed to the aluminum sill support 12 with bolts.

  Further, the apron 15 is fixed to the car sill support 12 made of an aluminum material with bolts through an apron bracket 31. The protective cover 14 of the sill added to the car sill is bolted to the sill 13 and the apron 15 added to the aluminum car sill, and is attached to prevent the car sill and the human foot from being caught. It has been. Further, the sill added to the car sill and the protective cap 16 of the protective cover are fixed to the sill 13 added to the aluminum car sill and the protective cover 14 of the sill added to the car sill with bolts. This is also attached for the purpose of preventing the car sill from being caught between human feet.

  On the other hand, details of the car sill portion in the stainless steel material specification are as shown in FIGS. A stainless steel car sill support 22 is fixed to the car floor frame with bolts, and a stainless steel car sill support 22 and a stainless steel car sill support 21 are also fixed with bolts. The sill 23 added to the stainless steel car sill is bonded and fixed to the sill support 24 added to the stainless steel car sill, and is fixed to the stainless steel car sill support 22 with bolts. ing.

  In addition, the apron 15 is fixed to the stainless steel basket sill support 22 with bolts via an apron bracket 31. The protective cover 14 of the sill added to the car sill is bolted to the sill support 24 and the apron 15 added to the stainless steel car sill for the purpose of preventing the car sill and the human foot from being pinched. It is attached. The sill added to the car sill and the protective cap 16 of the protective cover are fixed to the sill support 24 attached to the stainless steel car sill and the sill protective cover 14 added to the car sill with bolts. This is also attached for the purpose of preventing the cage sill and the human foot from being caught.

  The external dimensions of the sill 23 added to the stainless steel car sill and the sill support 24 added to the stainless steel car sill bonded and fixed are the same external dimensions as the aluminum car sill support 12.

  With this configuration, the protective cover 14 of the sill added to the car sill, the apron 15, the apron bracket 31, the sill added to the car sill and the protective cap 16 of the protective cover are common parts, and the same It can be a structural design. Further, the installation workability is the same, and it becomes possible to provide an elevator car sill in which the design and installation work of parts related thereto are made common.

  In the present embodiment, the structure in which the additional car sill 7 is attached to the part of the car sill 6 facing the landing has been described as an example. However, the landing sill for opening and closing the landing door is each There is also a landing. Therefore, a structure in which a sill is further added to a part where the landing sill is opposite to the car can be used. In that case, the same effect can be achieved by configuring the added sill as described in this embodiment. Can do.

  As explained above, the aluminum structure car sill and the stainless steel car sill only have different surface materials and the same external shape, but the internal structure has been greatly different in the past. I was doing structural design. Due to the difference in structure, the mounting workability is also different. This problem can be solved by making the parts shape of the aluminum material specification car sill and the stainless material specification car sill the same. In other words, only the outer surface of a stainless steel car sill is covered with stainless steel, and the interior is made of a stainless steel car sill with a structure equivalent to an aluminum car sill. can be solved.

  Therefore, with the configuration as described in the present embodiment, the outer shape of each part handled in the aluminum material specification and the stainless material specification has the same dimensions, so the related parts attached to this must also have the same structural design. Can do. Moreover, the installation workability | operativity becomes the same and can provide the elevator car sill which shared the design and attachment work of the components relevant to this.

  In the above embodiment, aluminum is used as the inexpensive material and stainless steel is used as the metal cover material. However, as a low-priced material, a material having sufficient strength as an additional sill may be used. For example, a resin material such as ABS or plastic, iron, or the like may be used. Similarly, as the metal cover material, an expensive metal such as gold or copper can be used. For example, a configuration in which resin is used as an inexpensive material and aluminum is used as a metal cover material may be used.

  Here, the low-priced material means a material with a low material unit price when compared with a metal cover material in terms of a unit price. By adopting such a configuration, while reducing the amount of high-cost material used, only the outer surface portion is made of a surface finish of a different material, so that the sill is formed of a high-cost material in appearance. It can be seen and the design of the elevator can be improved.
