BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view showing a usage state of the present invention, FIG. 2 is an enlarged sectional view showing a column portion of the same, and FIG. 3 is a rear view showing a mounting state of a personal computer table. 4 is a side view of the above.

A workbench A according to the present invention comprises a base 1, a column 10 standing upright on one side of the platform 1, and a personal computer table 30 supported on the upper end of the column 10, and has a front shape. It is almost U-shaped.

As shown in FIG. 1, the base 1 is formed in a substantially L-shape in a plane for maintaining stability, and is used by being sandwiched between the bottom of the seat 3 of the seat 2. In the figure, 4 indicates a backrest.

The column 10 is made of a plastic or metal pipe material, and has a base column 11 vertically erected and fixed on the base 1 and a base column 11 having a lower portion.
Further, it is provided with an elevating column cylinder 12 which is rotatably in the horizontal direction and is vertically movable, and a height adjusting mechanism 13 of a personal computer table 30 supported on the upper end of the elevating column cylinder 12.

The elevating column cylinder 12 is bent and formed in an inverted L shape in the front shape, and the horizontal portion 12a at the upper end is positioned above the base 1 for use. Therefore, the horizontal portion 12a is formed to have the same length as that of the base 1.

Further, the base column 11 is internally fixed with cylindrical metal 14, 14 for the elevating column 12 at both upper and lower ends thereof. Among these, a hole 15 having a large diameter is opened in the upper metal 14, and the base cylinder 1 facing the hole 15 is formed.
1 also has a small bore 16 with a common axis.

Further, on the outside of the base cylinder 12, a nut 1 having a screw hole 17a having a common axis with the hole 16 is formed.
7 is fixed, and the screw shaft 18a of the cap screw 18 is screwed into the screw hole 17a of the nut 17. In this way, the height adjusting mechanism 13 of the personal computer table 30 is provided outside the elevating column 12.

When the cap screw 18 of the height adjusting mechanism 13 is rotated to advance the screw shaft 18a, the tip of the screw shaft 18a pushes the outer surface of the elevating column cylinder 12, so that the elevating column cylinder 12 is moved within the base column cylinder 11. It can be fixed after being adjusted at a predetermined height position.

Thus, the vertical portion 12 of the lifting column cylinder 12
A disc-shaped receiving metal 19 is internally fixed above b, and a spring 20 for urging the elevating column cylinder 12 upward is interposed between the receiving metal 19 and the base 1.

A support fitting 21 is attached to the center of the lower surface of the receiving metal 19, and the support fitting 21 and a hole 22 projecting from the center of the base cylinder 11 of the base 1 are inserted and fixed from the outside. The ascending rising point positioning cables 24 of the ascending / descending columnar cylinder 12 are respectively bound between the supported metal fittings 23. In addition,
The cable 24 has a function of preventing the lifting column cylinder 12 from coming off from the base column 11. In the figure, reference numeral 25 indicates a support for the base cylinder 11 on the base 1.

The personal computer table 30 includes a table 31 for the personal computer body 33 and a table 3 for the mouse 34.
The table 31 is separated into the table 32 and the table 31 at the front of the horizontal portion 12a at the upper end of the column 10 (on the left side when viewed from the chair 2).
Are fixed by a support 35 at a slight distance to the rear (right side when viewed from the same direction).

As shown in FIGS. 3 and 4, the support 35 is provided with each table 31, 32 of the personal computer table 30.
Plural pieces (each table 31, 32 in the illustrated example) on the left and right sides slightly in front of the center of the lower surface (front side when viewed from the chair 2).
(2 each).

Each of the supports 35 is provided with an insertion hole 36 for the support column 10 so as to open in a straight line in the left-right direction, and an angle adjusting mechanism 37 for the personal computer table 30 is provided on the outer surface.
Is provided. A cap screw 38 is also used as the angle adjusting mechanism 37. A screw hole 39 is provided in the center of the support 35 so as to communicate with the insertion hole 36, and the screw shaft 38a of the cap screw 38 is screwed into the screw hole 39.

By thus providing the angle adjusting mechanism 37 on the outer surface of each support 35, when the cap screw 38 is turned and the screw shaft 38a is advanced, the tip 10 thereof is inserted into the insertion hole 36 (ascending and descending). Since the outer surface of the horizontal portion 12a of the column 12 is pressed, the front and rear angles of the tables 31 and 32 of the personal computer table 30 can be adjusted to the most convenient angle and then fixed.

For the personal computer table 30, a rubber sponge plate 30b is attached to the upper surface of a plastic or metal substrate 30a. Further, in the illustrated example, the table 31 for the personal computer main body 33 and the table 32 for the mouse 34 are separated, but one personal computer table 30 may be used. Furthermore, the base 1
Can also be incorporated into the seat portion 3 of the seat 2 to be integrated.

Next, the operation of the present invention will be described. First, as shown in FIG. 1, the base 1 is laid under the seat 3 of the chair 2, and the personal computer table 30 is horizontally rotated to be positioned right above the base 1.

Then, the push screw 18 of the height adjusting mechanism 13 of the support column 10 is loosened to move the elevating column cylinder 12 up and down with respect to the base column cylinder 11 so that the height position of the personal computer table 30 can be used most easily. After the adjustment, the holding screw 18 is tightened to fix the lifting column cylinder 12.

Furthermore, by loosening the cap screw 38 of the angle adjusting mechanism 39 of the personal computer table 30 and rotating the support 35 around the elevating column cylinder 12 (horizontal portion 12a), the angle of the personal computer table 30 can be used most easily. Then, the support screw 35 of the personal computer table 30 is fixed to the elevating column cylinder 12 (horizontal portion 12a) by adjusting the holding screw 38.

[0025]

Since the present invention is constructed as described above, it has the following effects. According to the first aspect of the present invention, the base is laid under the seat, so that the height of the column and the angle of the personal computer table can be freely adjusted for use. It is extremely important to be able to work on a personal computer (notebook personal computer) while leaning against it, which contributes to reducing fatigue and reducing the burden on the shoulders and waist.

Further, according to the first aspect, since the personal computer table can be rotated 360 degrees in the horizontal direction, the personal computer table is an obstacle when sitting on or standing up in the chair. It is extremely convenient because it can be excluded.

Further, according to the second aspect, the personal computer table is divided into a left personal computer main body table and a right personal computer table, which are arranged separately. The front and rear angles can be adjusted separately for ease of use.
