[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support leg for a raised floor.

[0002]

2. Description of the Related Art The structure of a conventional free access floor is shown in FIG. The free access floor is used as a floor in offices, etc., and the support feet 13 are installed on the base floor 11,
The panel 15 is installed on the support legs 13 to form a double floor structure, and the wiring between the base floor 11 and the panel 15 such as telephone lines, power lines, and signal cables required for office equipment used in the office Is to be stored. The shape of the panel 15 is usually a square having a side of, for example, about 50 cm, and the support legs 13 are installed at positions that support the corners of the adjacent panels 15 from below.

A conventional supporting leg 13 is provided with a female screw cylinder 19 on a substrate 17.
And a height adjustment bolt 23 screwed into the female screw cylinder 19. The height adjusting bolt 23 has a flange portion 25 for supporting the panel 15 at the upper part. At the four corners of the panel 15, holes 29 for receiving the heads 27 of the height adjusting bolts 23 are formed.
After the setting of the panel 15 is completed, the panel 15 is closed by the lid 31.

[0004]

In the conventional support leg, the height of the panel is determined by rotating the height adjusting bolt to adjust the height of the flange portion. The height adjustment must be performed for each bolt, and it is extremely troublesome because it is easy to raise and lower too much. In the normal construction method, the so-called flooring method, in which the height of the panel from the foundation floor is fixed, is often used.In this case, the height of the flanges of the support legs may be uniform. On the other hand, in the case of a conventional supporting leg, it is extremely troublesome to make the height of the flange portion uniform.

[0004] When the height of the panel from the base floor is high, the length of screwing of the bolt into the female screw cylinder is short, so that the bolt is likely to rattle or run out, resulting in instability. .

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a pedestal having a female screw cylinder fixed vertically to a substrate, and screwed into the female screw cylinder. The height adjusting bolt is a support leg for a free access floor having a flange portion for supporting a panel at an upper part thereof, wherein the upper end of the female screw cylinder and the height adjusting bolt are provided. A height setting pipe is interposed between the flange portion and the flange portion.

[0006]

With this support leg, when the height adjusting bolt is screwed into the female screw cylinder until the pipe is tightened, the flange portion is fixed at that position. That is, if the length of the pipe is made constant, the height of the flange portion can be made uniform. Further, if the pipe is tightened with the height adjusting bolt, even if the length of the height adjusting bolt screwed into the female screw cylinder becomes short, the height adjusting bolt does not rattle or run out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention. The support leg 13 for the free access floor has a female threaded cylinder 19
And a height adjustment bolt 23 screwed into the female screw cylinder 19, and the height adjustment bolt 23 has a panel support flange 25 at the top. Is the same as before. The feature of the support leg 13 is that a height setting pipe 33 is interposed between the upper end of the female screw cylinder 19 and the flange portion 25 of the height adjusting bolt 23.

The height adjusting bolt 23 is screwed into the female screw cylinder 19 until the pipe 33 is tightened. As a result, the height of the flange portion 25 is determined by the length of the pipe 33. To increase the height of the flange portion 25, use a long pipe, and to decrease the height, use a short pipe. Usually, if the floor is the same, the height of the flange 25 is often constant.In such a case, the height of the flange 25 is kept constant by using a pipe 33 of the same length. Can be aligned.

When the pipe 33 is tightened with the height adjusting bolts 23, even if the length of the bolts 23 screwed into the female screw cylinder 19 is short, the bolts 23 do not rattle or move sideways, and the stability is improved. Increase. For this reason, there is also an advantage that the height adjustable range is widened by one set of the pedestal 21 and the height adjusting bolt 23. The material of the pipe 33 is metal or hard plastic.

FIG. 2 shows another embodiment of the present invention. The support leg 13 has a long pipe 33A and a short pipe 33A between the upper end of the female screw cylinder 19 and the flange 25 of the height adjusting bolt 23.
33B are interposed and these are tightened by height adjusting bolts 23. When the height of the flange portion 25 is slightly different depending on the location, a long pipe 33A having a fixed length and various short pipes 33B having different lengths are prepared as described above, and the short pipe 33B is replaced. You should respond to changes. Other configurations are the same as those of the embodiment of FIG. 1, and therefore, the same portions are denoted by the same reference numerals and description thereof will be omitted.

[0011]

As described above, according to the present invention, the height of the flange portion can be set by interposing the pipe between the upper end of the female screw cylinder and the flange portion of the height adjusting bolt. In addition to being extremely simple, there is an advantage that the height adjusting bolt does not rattle or run out, thereby improving stability.
