Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to, for example, a multi-stage personal computer desk, such as a table for placing a keyboard, a table for placing a display device (CRT), etc. Regarding a desk for equipping etc.

(Prior art and problems) Conventional multi-tier PC desks have a table for placing a display device on the top level and a table for placing a keyboard on the middle level, which protrude forward from the top level table to maintain their respective localization values. There is a so-called desk dedicated to computers.

Therefore, it was almost impossible to use this desk as a general office (study) desk because, for example, the keyboard table protruded forward and the width of the top table was narrow.

For this reason, a general individual user must purchase and install both a dedicated computer desk and an office (study) table, which is extremely uneconomical.

(Means for Solving the Problems) The present invention proposes a desk that can solve the conventional problems as described above. That is, in the desk according to the present invention, at least the top table 9, the middle table 8, and the bottom table 7 can be moved back and forth between a pair of vertical columns supported by horizontal bars at a required spacing. The end position of the uppermost table 9 is located at the center in the longitudinal direction of a rail 11 which is removably installed at the top and supports the left and right edges of the uppermost table 9 and guides the uppermost table so that it can move forward and backward. A pair of regulating stoppers 2
1 and 22 are provided in a protruding manner, and a gap 26 is provided between the pair of stoppers for locking the uppermost table 9 and an auxiliary table 23 of the same standard front and back in parallel.

(Example) In FIGS. 1 and 2, 1a and 1b are a pair of left and right vertical columns, which are supported by upper and lower horizontal bars 2a and 2b at a predetermined distance from each other. Each strut 1a or 1b has a horizontal base member 4 at its lower end that is equipped with free wheels (casters) 3 at both front and rear ends, and a front strut member that is erected in parallel in a state that is inclined diagonally backward from the horizontal base member 4. 5 and a rear support member 6.

7 is a bottom table, 8 is a middle table for placing a keyboard, and 9 is a top table for placing a display device, etc. Of these, the middle table 8 and the bottom table 7 are mounted on both left and right sides of a pair of left and right slide rails 10 that are installed horizontally between the front and rear support members 5 and 6 inside the pair of vertical supports 1a and 1b. The sides are fitted and supported so that they can be slid back and forth, and the uppermost table 9 has both left and right sides that are fitted and supported so that they can be slid back and forth by sliding rails 11 that have a different configuration from the rails. .

The tables 7 to 9 in each stage are constructed as shown in FIGS. 3 to 5. That is, the four sides of the top plate 12 made of a rectangular metal plate are bent downward to form front and rear side edges 12a, 12b and left and right side edges 12 of appropriate thickness.
A reinforcing material 13 is formed at the center of the bottom surface of the top plate 12 and extends between the left and right edges 12c and 12d.
A plastic cover 14 is fitted and fixed to the left and right edges 12c and 12d.

The reinforcing material 13 is made by bending the four sides of a band-shaped metal plate upward to form side edges 13 of an appropriate thickness, as shown in FIG.
A to 13c are formed, and the side edges 13c at both lengthwise ends are provided with fixing holes 16 that match the fixing holes 15 provided on the top plate side edges 12c and 12d. . Said top plate side edge 12c, 1
2d is also provided with fixing holes 17 near both ends in the length direction, and the cover 14 is provided with fixing holes 17 near both ends in the length direction, and the cover 14 has the side edges 12c, 1 of the top plate.
Fixing hole 1 that matches fixing holes 15 and 17 of 2d
8 and 19 are provided.

The cover 14 and the reinforcing material 13 can be secured to the fixing holes of the top plate side edges 12c and 12d by positioning the reinforcing material 13 at a predetermined position on the bottom of the top plate 12 and fitting the cover 14 to the top plate side edges 12c and 12d. 15, the fixing hole 16 of the reinforcing material side edge 13c, and the cover 14
Since the fixing holes 18 of the two are concentrically aligned, the fifth fixing hole 18 is attached to the top plate 12 by a blind rivet 20 inserted into each fixing hole 15, 16, 18 from the cover 14 side.
It is fixed as shown in the figure. Furthermore, cover 14
Both ends of the fixing holes 17 and 1 are aligned with each other.
9, fix the side edge 1 of the top plate using blind rivets, self-tapping screws, screw nuts, etc.
It can be fixed to 2c and 12d. Of course, self-tapping screws can be used instead of the blind rivets 20, and the reinforcing material 13
You can also use screw nuts etc. by providing a window for operation.

The cover 14 is slidably fitted into the slide rails 10 and 11, and
Each table 7 to 9 and metal slide rail 1
This is also useful in preventing the generation of metallic sounds when sliding contact is made between the tables 7 and 11, and in making each table 7 and 9 slide smoothly.

Among the tables having the above structure, the uppermost table 9 is slidably fitted to the slide rail 11, and stoppers 21 and 22 for regulating the front and rear slide end positions, and the stopper 2
1 to lock an auxiliary table 23 of the same structure will be explained with reference to FIGS. 6 to 8.

That is, as shown in FIG. 8, this slide rail 11 fits the upper ends of the support members 5 and 6, and
A downward U-shaped column fixing frame 11a for removably fixing with screws 24 (see Figures 1 and 6), and a rail frame 11b inside thereof.
The rail frame portion 11b consists of a lower rail piece 25 extending horizontally over its entire length in the front-rear direction, and a pair of lower rail pieces integrally projecting upward with a required opposing gap 26 provided at the longitudinal center of the lower rail piece. stoppers 21 and 22, and an upper rail piece 27 that faces the lower rail piece 25 and extends horizontally only in the central portion of its entire length. And left and right side edges 12c of the top table 9 having the above structure,
12d, more precisely, the covers 14, 14 are placed between the upper and lower rail pieces 25, 27 of the rail frame 11b,
In addition, as shown in FIG.
1 and 22 are fitted together. As a result, the top table 9 has a left side edge 12a in the figure.
The right side edge 12b can slide to a retreat position shown by a solid line when the stopper 21 is regulated to abut against it, and to a forward position shown by a phantom line when the right side edge 12b is regulated from abutment to the stopper 22.

A further feature of the present invention is that the required gap 26 between the pair of stoppers 21 and 22 is
This is because we have established the following. Therefore, when using it for general office work (study) or as a work table, first remove the left and right slide rails 11, 11 from the support members 5, 6 by loosening the screws 24, and as shown in FIG. The upper table 9 and the auxiliary table 23 of the same structure and standard are arranged side by side, and the left and right slide rails 11, 1 are installed with their adjacent side edges 12a, 12b fitted into the gap 26.
By screwing 1 to the support members 5 and 6 again, both tables 9 and 23 become a pair of stoppers 2.
1 and 22 so that it is fixed without moving, and can be used as a general desk with a wide table surface. Although the auxiliary table 23 may be provided separately, the middle table 8 or the lowest table 7 may be separated from the slide rails 10, 10 and used as the auxiliary table 23.

In addition, the other tables other than the top table 9, that is, the middle table 8 and the bottom table 7, have sliding rails 10 that have a separate structure, so that their longitudinal slide strokes are controlled as shown by solid lines and imaginary lines in FIG. The stopper structure, which is a feature of this slide rail 10, will be explained with reference to FIGS. 9 to 14.

That is, 28 is a stopper made of a spring wire, and is a lower rail of one or both of the pair of left and right slide rails 10, 10 that slidably support the left and right sides of the tables 7, 8. It is attached to piece 29.
As shown in FIGS. 13 and 14, this stopper 28 has a U-shaped attachment portion 28 formed at a central position in the length direction so as to protrude horizontally and laterally.
a, and an inverted V formed so as to protrude upward at a symmetrical position apart from the mounting portion 28a on both ends.
C-shaped protrusions 28b and 28c, and upward hook portions 28 formed at both ends to be bent laterally.
d and 28e, which are fixed to the bottom of the lower rail piece 29 at the mounting portion 28a with screw nuts 30, and both protruding portions 28b and 28c.
protrudes upward from a pair of front and rear elongated holes 31a, 31b provided in the lower rail piece 29 at the locations where the sides (cover 14) of the tables 7, 8 slide, and furthermore, upward hook portions 28d at both ends. ,28
e projects inside the lower rail piece 29 into the moving path of the tables 7 and 8.

In the stopper structure configured as described above, when the tables 7 and 8 are in the rear retracted position B as shown by solid lines in FIGS. 9 and 10, the rear end upward hook portion 28e of the stopper 28 is Lower end 32 of the front side edge 12a of the top plate of tables 7 and 8
9 and 10 to prevent the tables 7 and 8 from moving further rearward.
When the tables 7 and 8 are in the forward use position A as shown by the imaginary lines in the figure, the front end upward hook portion 28d of the stopper 28 engages with the lower end 32 of the top plate rear side edge 12b of the tables 7 and 8. This prevents the tables 7, 8 from moving further forward.

When the tables 7 and 8 in the use position A or the retracted position B are moved backward or forward, the bottom surfaces of the sides of the tables 7 and 8 (the bottom surface of the cover 14) are moved to the stopper 28 as shown in FIG. The inverted V-shaped protrusions 28b and 28c are pressed down and the stopper 28 is bent downward against the elasticity using the mounting portion 28a as a fulcrum, so that the upward hook portions 28d and 28e at both ends follow the movement path of the tables 7 and 8. Escape below. Therefore, the tables 7 and 8 can be slid back and forth without coming into contact with the hook portions 28d and 29e. When the tables 7 and 8 cross the area between the pair of inverted V-shaped protrusions 28b and 28c at the front and rear of the stopper 28,
The stopper 28, which had been deformed by being pressed against the protrusions 28b and 28c, returns elastically, and the rear end upward hook portion 28e is attached to the lower end of the front side edge 12a of the top plate of the tables 7 and 8 that have reached the rear retracted position B. 32, and the front end upward hook portion 28d engages with the lower end 33 of the top rear side edge 12b of the tables 7 and 8 that have reached the front use position A.

Note that in order to remove these tables 7 and 8 from the slide rails 10 and 10, one of the hook portions 28d or 28e of the stopper 28 is pressed.
The engagement state is released by bending the mounting portion 28a further downward from the lower side edges 33, 33 of the tables 7, 8 against the elasticity of the mounting portion 28a, so in this state, the table 7, 8 can be pulled out from the slide rails 10, 10 and used, for example, as the aforementioned auxiliary table 23.

When using a desk with the above structure as a computer desk, the display position is placed on the top table 9, the keyboard is placed on the middle table 8, and the computer body, floppy desk drive device, etc. or other materials are placed on the bottom table 7. Either they are placed as paper holders, or the vertical supports 2a and 2b are made slightly longer, and two or more intermediate tables are provided between the top table 9 and the bottom table 7.
The printer may be placed on the top table 9, and the above-mentioned devices may be placed sequentially toward the lower table. In addition, since the tables other than the top table 9 can be made to protrude long backwards, any of the tables can be made to protrude backwards to serve as a holder for printed paper sent out from the printer placed on the top table. It can be used.

Furthermore, when reusing it as a table for general office work, etc., the auxiliary table 23 is locked and fixed to the top table 9 in parallel to the top table 9 by the above-mentioned operation, and the middle and lower tables are locked. If the table is set back long, it can be used for other purposes smoothly without being hindered by these objects.

(Effects) As described below, according to the present invention, general users can use it as a computer desk, and by simple replacement, it can be converted into a desk for general office (study) use, etc. It is very economical.

Furthermore, the manufacturer can manufacture it as a computer desk as well as a desk for general office work, etc., and since the number of parts and manufacturing process remain the same, it is suitable for mass production and can be manufactured at low cost. be able to.
