Description

[Detailed Description of the Invention] The present invention relates to a pillar mounting device, and its purpose is to provide a pillar mounting device that allows easy installation of a pillar and facilitates height adjustment.

As shown in FIG. 4, the conventional column mounting device involves inserting the lower part of the cylinder 13 into the upper part of the column 1, and inserting the pin 15 inserted into the elongated hole of the column 1 into the cylinder 13. The upper part of this cylinder 13 is fitted into the inner peripheral part of the upper rail 6, and the upper part of the column 1 is connected to the ceiling 1.
6, and a receiving frame 14 is fixedly inserted into the lower part of the column 1, and the lower part of the bolt 10 screwed into the receiving frame 14 is screwed to the lower rail 8, and the column 1 is fixed to the lower rail 8. The lower part of the nut 1 is fixed to the floor 17, and the nut 1 is fixed to the approximate center of the bolt 10.
By rotating the column 2, the vertical position of the column 1 can be adjusted.

However, in the conventional example described above, if the height of the ceiling 16 is low, the height of the column 1 cannot be adjusted, so it is necessary to prepare a column 1 of a different height. , ceiling 1
This has the disadvantage that it is necessary to prepare several types of columns 1 with different lengths depending on the height of the column 6, which complicates the construction work.

The present invention has been proposed in view of the above-mentioned points, and will be explained in detail below with reference to Examples.

Figure 1 shows the relationship between the upper part of the column 1 and the upper rail 6, and Figure 2 shows the relationship between the lower part of the column 1 and the lower rail 8. The body part 4 of the upper cover 2 as shown in Fig. 3 can be press-fitted into the upper opening, and the lower opening has the same shape as the upper cover 2 shown in Fig. 3. The body part 4 of the lower cover 3 can be freely press-fitted.

Both the upper cover 2 and the lower cover 3 each have a flange 5,
The upper and lower covers 2 and 3 are attached to the top and bottom of the column 1, respectively, with the collar 5 abutting the upper and lower peripheral edges of the column 1, respectively.

Reference numeral 7 denotes an upper box-shaped body having a width approximately equal to the inner width of the upper rail 6 having a substantially U-shaped cross section, and capable of being fitted into the inner circumference of the upper rail 6; A square bar 18 hanging down from the center of the lower part of 7 is inserted into a square through hole 11 bored in the upper cover 2 so as to be vertically movable but not rotatable.
A coil spring 20 fitted around the outer periphery of the housing 8 is disposed between the upper box-shaped body 7 and the upper cover 2 to bias the upper box-shaped body 7 upward.

The lower rail 8, which has a substantially U-shaped cross section, is disposed on the floor surface with the opening facing upward, has a width approximately equal to the width of the lower rail 8, and is fitted into the inner circumference of the lower rail 8. The upper part of the bolt 10 erected on the upper surface of the lower box-like body 9 is inserted into a through hole 11 bored in the center of the lower cover 3.
The column 1 is held upright on the lower rail 8 by abutting the upper surface of the nut 12 screwed onto the bolt 10 against the lower surface of the lower cover 3.

When adjusting the height position of the column 1 interposed between the upper rail 6 and the lower rail 8, rotate the nut 12 to move the column 1 upward or downward through the lower cover 3. Move it to .

As described above, the present invention forms a columnar body by covering the upper and lower openings of the rectangular columnar body with an upper cover and a lower cover.
The length of the column can be cut to an appropriate length at the construction site depending on the height of the ceiling, and unlike conventional methods, columns of various lengths can be prepared depending on the height of the ceiling. This eliminates the need for an upper box, which reduces costs, and allows the upper box-like body, which can be fitted into the inner circumference of the upper rail with a substantially U-shaped cross section and is biased upward by a spring, to be movable up and down by the upper cover. , when installing a column between the upper and lower rails, fit the upper box-like body into the upper rail and lift the column upward to shorten the distance between the upper box-like body and the column, then lower the bottom of the column. It only needs to be attached to the rail, which simplifies the installation of the column, and once the column is attached, the upward spring biasing force of the upper box-like body prevents the column from collapsing between the upper rail and the lower rail. A bolt can be placed upright on the top of the box-shaped body, which can be installed without sticking, and can also be fitted into the inner circumference of the lower rail, and the upper part of this bolt is inserted into the vertical through hole of the lower cover. Since the nut screwed onto the bolt is placed in contact with the bottom of the lower cover, the height of the column can be easily adjusted by simply turning the nut.This is especially true for columns arranged in parallel. When installing a shelf support or the like and mounting the shelf between both shelf supports, there is an advantage that the height of the column can be freely adjusted and the shelf can be installed accurately.

In addition, the upper box-like body that can be fitted into the inner circumference of the upper rail, which has a roughly U-shaped cross section, is held by the upper cover so that it does not rotate, so when installing the column between the upper and lower rails, it is possible to It can be easily installed by aligning the outer surface of the cylindrical column so that it is parallel or perpendicular to the upper and lower rails, and
This has the effect that the column does not rotate when the height of the column is adjusted by rotating the adjustment nut.

In other words, by preventing relative rotation between the upper box-like body and the column, and by fitting the upper box-like body into the upper rail to prevent rotation of the upper box-like body with respect to the upper rail, Since rotation of the column relative to the rail is indirectly prevented, the height of the column can be adjusted freely, and each outer surface of the column can be maintained at a constant angle with respect to the vertical plane even when adjusting the height. This effect is particularly important because shelf mounting holes are drilled on one side of the rectangular cylindrical column (for example, the front side), so the shelf with limited directionality can be mounted up and down. This is noticeable when installing between rails.
