Description

  The present invention relates to a car floor of an elevator that can easily adjust the dimension of the car floor in the depth direction.

As a conventional elevator car floor, for example, there is a structure as shown in FIG.
In FIG. 5, a C-type channel 2 is welded to the lower surface of the front end portion of the steel-made floor frame 1 constituting the elevator car floor. An L-shaped angle 4 made of steel that receives the sill 3 is fixed to the front surface of the C-shaped channel 2 by a bolt 5. Further, a sill 3 having a sill groove is fixed to the upper surface of the L-shaped angle 4 by a bolt 6. In addition, on the upper surface of the floor frame 1, the tile 7, which is a rug of a car floor, is arranged so that the upper surface 7 a of the tile and the upper surface 3 a of the sill 3 are substantially flush with each other, and there is a gap between the tile and sill mating surfaces. It is fixed by bonding or the like so as not to occur. In a car floor constructed in this way, once the tile and sill have been assembled, the tiles are designed so as not to impair the appearance of the mating surface of the sill and tile when attempting to adjust the position of the sill. You need to scrape or paste it again. Moreover, since the adjustment of the threshold is only the margin of the mounting hole of the threshold, the adjustable range is limited.

  Further, as a conventional technique, there is one that does not impair the appearance of a mating surface of a carpet that is a sill and a rug (see, for example, Patent Document 1).

JP-A-8-198560

In conventional elevator car floors, after assembling the tiles and sills, if you try to adjust the position of the sill, do you want to scrape the tiles so as not to impair the appearance of the mating surfaces of the sill and tiles? , You need to paste it again. Moreover, since the adjustment of the threshold is only the margin of the mounting hole of the threshold, the adjustable range is limited.
By the way, when an elevator car is installed in a hoistway of a building, it is necessary to set the distance between the floor sill of each floor of the building and the sill of the car within a certain range. However, since it is very difficult to adjust the dimensions of the car once assembled as described above, the installation accuracy of the car and the sill on the landing side and the assembly accuracy of the car floor have become very strict. . In particular, in elevators with two-way entrances, higher installation accuracy and assembly accuracy are required so that the distance between the floor sill and the car sill in each direction is within a certain range of dimensions. It was done. For this reason, there has been a problem that the processing cost of the car floor is increased and the time required for installation is increased.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide an elevator car floor that can easily adjust the dimension of the car floor in the depth direction.

  The elevator car floor according to the present invention includes a floor frame constituting the elevator car floor, a sill body fixed to the front end portion of the floor frame, having a sill groove, and a front end portion of the sill body. Convex parts with different lengths on the diagonal, and with a separate sill that can adjust the size in the depth direction of the car floor by selecting and fixing the mounting direction to the sill body appropriately It is.

  According to this invention, the dimension in the depth direction of the car floor can be easily adjusted by appropriately selecting and fixing the direction of attaching the separate sill to the sill body.

Embodiment 1.
1 is a cross-sectional view of a main part showing a sill portion of an elevator car floor according to Embodiment 1 of the present invention, and FIG. 2 is a longitudinal cross-sectional view showing a separate part of the sill of the elevator car floor according to Embodiment 1 of the present invention. It is.

  In the figure, a C-type channel 2 is welded to the lower surface of the front end portion of a steel-made floor frame 1 constituting an elevator car floor. An L-shaped angle 4 made of steel that receives the sill body 31 is fixed to the front surface of the C-shaped channel 2 by a bolt 5. A threshold 31 having a threshold groove is fixed to the upper surface of the L-shaped angle 4 with a bolt 6. Further, on the upper surface of the floor frame 1, the tile 7 or the like which is a rug of a car floor is arranged so that the upper surface 7a of the tile and the upper surface 31a of the sill body 31 are substantially flush with each other, and the mating surface of the tile and sill is a gap It is fixed by adhesion or the like so as not to occur. The configuration so far is substantially the same as the conventional one, but the depth dimension of the sill body 31 having the sill groove is smaller than the depth dimension of the sill 3 having the conventional sill groove. In the present invention, there is provided a separate sill body 32 that can adjust the depth dimension width of the entire sill, that is, the dimension in the depth direction of the car floor, by appropriately selecting and fixing the mounting direction on the front end surface of the sill body 31. It is fixed. In this separate sill 32, convex portions 32a and 32b having different lengths t1 and t2 are provided so as to protrude in the horizontal direction at the upper end portion on one side and the lower end portion on the other side diagonally thereto. The height of the separate sill 32 is slightly larger than the height of the sill main body 31, and when the sill separate 32 is mounted, the lower end of the front end surface of the sill main body 31 is a step of the convex portion 32a or 32b. Is to be housed in the department. In addition, a plurality of screw holes 31b are constructed along the longitudinal direction on the front end surface of the sill body 31, and a plurality of attachment holes 32c are constructed along the longitudinal direction of the central portion of the separate sill 32. The sill separate body 32 is fixed to the front end surface of the sill body 31 by screwing a plurality of P pan-head screws 8 as connecting tools inserted into the mounting holes 32 c into the screw holes 31 b of the sill body 31. As shown in FIG. 1, when the protrusion 32 a of the separate sill 32 is mounted with the protrusion 32 a facing upward, the sum of the depth dimension width of the sill main body 31 and the depth dimension width b 1 of the separate sill body 32 is the depth dimension of the entire sill. In contrast to FIG. 1, when the convex part 32 b of the separate sill body 32 is mounted on the upper side, the sum of the depth dimension width of the sill body 31 and the depth dimension width b 2 of the separate sill body 32 is the entire sill. It becomes the depth dimension width of.

  Therefore, according to the above configuration, the depth dimension width of the entire sill, that is, the dimension in the car floor depth direction can be adjusted by the direction in which the sill separate body 32 is attached (assembled) to the sill body 31. That is, the adjustment allowance for the difference (t1-t2) in the length of the convex portion of the separate sill 32 is increased. Further, by dividing the separate sill body 32 into a plurality, it is possible to set the sill interval of only necessary portions without using extra material.
