Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to elevator cars.

[0002]

2. Description of the Prior Art FIG. 5 is a schematic view showing a cross section of a hoistway wall of an elevator in which a conventional elevator car is suspended. 6 (a) is a right side view of the elevator car 1A shown in FIG. 5 (that is, a view taken along the line CC in FIG. 5), and FIG. 6 (b) is an enlarged detailed view of a C portion in FIG. Is.

In FIG. 5, inside the hoistway wall 3 provided at one corner of the building in which the elevator is installed, the outer periphery is shown by a chain double-dashed line and the right side view is shown in FIG. 6 (a). Is suspended on one side of a main rope (not shown) hanging from a deflecting sheave of a hoisting machine installed in a machine room at the upper end of the hoistway. On the right side of the car 1A, there is shown a counterweight 13 also suspended on the other side of the main rope.

On the inner surface of the hoistway wall 3, guide rails (not shown) are installed at positions facing the center of the car 1A and the front and rear surfaces of the weight 13 in FIG. On both sides, a plurality of guide rollers (not shown) attached to the car 1A and the counterweight are pressed.

In FIGS. 5 and 6, the bottom surface of the car 1A is made of channel steel on the upper surface of the car floor 21 at the lower end of the car 1A. Is fixed. In this skirting board 20, rectangular window holes 20a shown by broken lines in FIG. 6 are formed in advance at three locations on each side. A strip-shaped baseboard 19 is attached to the inner side surface of the baseboard 20.

At the left end of the upper surface of the car floor 21, a pair of pillars 5 are erected, the lower ends of the pillars 5 are fixed to the car floor 21 with bolts 9C, and the curtain plate 18 is laterally provided at the upper ends of the pillars 5. It is set up. On the right side of the pillar 5, the cross section is bent outward in a U shape,
Side plates 7E having a narrow lateral width whose upper and lower ends are also bent outward are placed on the upper surface of the skirting board 20 and fixed by bolts 9C.
The left end of the side plate 7E is bolted to the column 5.

On the right side of the side plate 7E, a wide side plate 7F whose upper, lower, left and right sides are bent outward is placed on the upper surface of the skirting board 20, and is fixed to the side plate 7E and the skirting board 20 with bolts.
Similarly, on the right side of the side plate 7F, a side plate 7G having the same width as the side plate 7E and formed symmetrically with the side plate 7E is shown in detail in FIG.
As shown in (b), the side plate 7 is placed on the upper surface of the skirting board 20.
It is fixed to F and skirting board 20 with bolts.

Further, on the right side of each side plate 7G, a back side plate 8C is placed on the skirting board 20, and as shown in FIG. 6 (b).
One side is fixed to the side plate 7G with bolts 9A and nuts 10,
The lower end is fixed to the skirting board 20 with bolts 9C. Between these rear side plates 8C, a rear side plate 8D having the same width as the rear side plate 8C is placed on the skirting board 20, and the side surface is the rear side plate 8C.
It is fixed to the skirting board 20 with bolts 9C.

The tips of the bent portions formed on the side surfaces of the side plates 7E, 7F, 7G and the rear side plates 8C, 8D are shown in FIG.
As shown in (b), the side plates 7E, 7F, 7G and the rear side plate 8 are further bent inward at a slight angle of 90 °.
Bending portions 7a and 8a are formed by increasing the vertical rigidity of C and 8D. Therefore, the tightening portion formed by the bolt 9A and the nut 10 shown in FIG.
It is surrounded by 8a.

At the upper end of each of the side plates 7E, 7F, 7G, the rear side plates 8C, 8D and the curtain plate 18, a ceiling plate 14 bent in a substantially inverted convex shape is placed. The outer periphery of is fastened to the upper ends of the side plates 7E, 7F and 7G, the rear side plates 8C and 8D and the curtain plate 18 with bolts (not shown).

The bolt tightening work of the side plates 7E, 7F, 7G and the rear side plates 8C, 8D and the skirting board 20 is carried out before mounting the skirting board 19 shown in FIG. As disclosed in the official gazette, it is performed from the inside of the car floor 21 using a window hole 20a formed in the skirting board 20.

On the other hand, the bolting work among the side plates 7E, 7F, 7G, the back side plates 8C, 8D and the pillar 5 is performed by the outer side of these side plates and the back side plate and the hoistway wall 3 shown in FIG.
To and from the inside.

At this time, because of the relationship performed in parallel with the assembling of the counterweight 13, the elevator car 1A is carried out at the uppermost floor position of the hoistway, that is, the counterweight 13 is at the lowest position. Therefore, work scaffolds are assembled on the top floor of the hoistway.

[0014]

[Problems to be Solved by the Invention] However, the bolting work between each side plate and between each side plate and the back side plate is more and more restricted due to the increase in the land price in the city, which restricts the occupied floor area. Depending on the hoistway, it must be done in a dark place between the inner wall of the narrow hoistway and the car.

Moreover, as shown in FIG. 6 (b), the bolt 9A and the nut 10 have the side plates 7E, 7F, 7 as described above.
Since the inside is surrounded by the bend 7a formed in G and the inside of the narrow space surrounded by the bend 7a and the bend 8a of the back side plate 8C, the workability of mounting and operating the tightening tool is poor. .

Therefore, if the tightening tool is not properly attached, the tip of the tool comes off from the head of the bolt 9A and the nut 10, so that the finger holding the tool hits the cut surface of the bent portion 8a. There is also a risk of injury.

In addition, these works must be completed within a limited time, which is limited by the schedule such as other interior work of the building in which this elevator is installed. Therefore, as a measure to improve the workability of these assembling work, a method of preventing the tip of the tightening tool from coming off by adopting a thicker head and nut than the Japanese Industrial Standard is also adopted. , Still, it is difficult to perform the tightening of the bolts and nuts surrounded by the bent portions 7a and 8a as shown in FIG. 6 (b) at the high place where the narrow and dark posture is restricted as described above.
Moreover, these operations are required to have high reliability because of the elevator that is responsible for human life. Therefore, an object of the present invention is to obtain an elevator car capable of improving workability and safety of assembly.
