Abstract

PURPOSE:To attain the operation of an electronic computer in both standing and seated postures of an operator by setting an upper housing containing a computer main body, a keyboard part and a display part to a lower housing in an up-down controllable way. CONSTITUTION:An electronic computer is used at the height l when an operator is sitting on a chair. When the computer is used by a standing operator, the operator operates a handle 20 to release the fixed state between an upper housing 3 and a lower housing 8 and moves up the housing 3 to fix it again by the handle 20. In this case, the housing 3 is balanced in its weight by an air spring device 19. The distance A between an opening part 7 and a top plate 4 has no change despite the up-down movements of the housing 3. Therefore, the operability is never deteriorated when a floppy sheet is loaded and unloaded. When the height of the housing 3 is small, the operator pushes a small barrel 15 down by means of a push rod 17 to flow the cooling air through a venthole 14. When the operator is standing, the barrel 15 is pushed up by a spring 13 and therefore the air is supplied through a venthole 12 of the housing 8. Dust is eliminated through a filter barrel 16.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a computer support device,
More specifically, the present invention relates to a computer support device #, I/c that is suitable for work while sitting on a chair and work while standing.

[Conventional technology]

Conventional computer support devices have different heights for work while sitting on a chair and those at a height for work while standing.

[Problem to be Solved by the Invention 1] The conventional computer support device as described above is not suitable for both standing work in the field and sitting on a chair in the office due to the difference in work styles between the office and the field. It is necessary to prepare one with a different structure, which is not only uneconomical, but also inconvenient because the button is not versatile.

This invention was made to solve the above-mentioned problems, and it is suitable for both standing and sitting work, and
The object of the present invention is to obtain an electronic computer support device that is economical and has a wide range of uses.

Another invention of the present invention is a computer support device that secures the flow of cooling air to the computer body during both standing work and sitting work, and prevents malfunctions due to dust accompanying the air flow. The purpose is to obtain.

[Means for solving problems]

The computer support device according to the present invention includes a rectangular cylindrical lower box with an open top end and a bottom, and a display portion and a keyboard portion with an open bottom end. It has a rectangular cylindrical upper box body with a top plate that is attached to the lower box body.

The computer body is supported within the upper box, and the height of the upper box can be changed.

In a computer support device according to another aspect of the present invention, a small cylinder, which is biased upwardly by a spring and has an air hole in its peripheral wall, is movable up and down in the center opening of the bottom plate of a lower box body having an air hole formed in the side wall. A vertically extendable filter tube is disposed between the bottom plate and the main body of the computer, and a push rod is provided to push down the small tube when the upper box body is lowered.

[For production]

In this invention, the height of the computer can be arbitrarily selected by moving the upper box up and down with respect to the lower box.

In another aspect of the present invention, when the upper box body is in the lowered position, cooling air flows into the interior through the air holes of the small cylinder. When the upper box is in the raised position, cooling air flows in through the air holes in the side wall of the lower box, and dust is captured by the filter tube.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Below, drawings representing an embodiment of the present invention will be described. In FIG. 1, the keyboard part (1) and the display part (1) are
Top plate (4I) of square cylindrical upper box (3) with open bottom
It is listed above. The floppy disk device (!) and the computer main body (6) are each stored in the upper box (3).
Supported. 91 of the upper box body (3)! The opening (1) in the wall is used to take in and take out the floppy disk sheet. Casters (10) are attached to the bottom plate (9), and the side walls (//)
K is provided with a large number of air holes (l2). In addition, the center opening (/1) IIC of the bottom plate (9) has a spring (13
) A small cylinder with a bottom that is forced upward from the IC and has an air hole (ta) formed in the lower circumferential wall (the lance is attached to the vertical ringer. Between the computer main body (6) and the bottom plate (9) for.

A lantern-shaped or accordion-shaped filter tube (16) that is vertically extendable and retractable is attached.

In addition, a push rod (l) is protruded from the bottom of the computer main body (6), and when the upper box body (, 7) is lowered as shown in Fig. 1, the push rod (17) is used to push the small cylinder. (tS) is pushed down against the force of the spring (13).

(tq) shown in Figure WE2 balances the weight of the keyboard part (1) 1 display part (Y) between the upper box body (3) and the lower box body (ffl), and the upper box body is moved with a small force. (
3) It is an air spring device to raise and lower and stabilize.

(O) is a stopper handle for fixing the position of the upper box body (,?) at a desired height.

FIG. 3 shows the upper box body (3) in a high position. In addition, in FIGS. 1 and 3, 1. L indicates the height from the floor to the top plate, and A indicates the distance from the top plate (4I) to the center of the opening.

Arrows indicate the flow of cooling air.

With the above configuration, when working in a sitting position, the chair is used at a height J (approximately 700tx) as shown in Figure 8g1.

When using it for standing work, operate the handle (O) to release the fixation between the upper box body (3) and the lower box body (g), and adjust the height of the upper box body (, 71) as shown in Figure 3. Lift it to L (approximately 10t) and secure it again from the no-endor (ko0) IC.

At this time, the weight of the upper box body (31) is balanced by the near spring mounting, so it can be moved.Also, even if the upper box body (3) goes up and down, the opening (ri) ,
Since the distance A from the top plate f4' is constant, the operability of putting in and taking out the floppy sheet is not lost.

Also, when the upper box body (3) is placed in a low position as shown in Figure @1, the small f5 (tr) is pushed down with the push rod, so the cooling air flows through the air hole (t(I)). direct inflow,
When using a seated chair in an office with relatively little dust,
By passing the cooling air through the filter tube (tt) Vc, the air path resistance is increased, and it is possible to avoid increasing the load on the fan (not shown).

When used in a standing position at a dusty site, the push rod (17) is at the top as shown in Figure 3, so the small tube (tS) is pushed up by the spring (13), and air flows through the air hole (ta).
), but instead enters through the air hole (No. 2) in the lower box, the dust is separated by the filter tube (16), and flows into the computer body (6) through the cleaning button, preventing malfunctions due to dust. can. The filter cylinder (16) is shaped like a lantern or an accordion and is vertically expandable and retractable, so that even if the upper box body (3) is in an intermediate position, it can sufficiently fulfill the role of dustproofing.

In addition, the caster (10') I/C allows for easy movement between the office and the field.

In the above embodiment, the upper box body (3) is fitted to the outer side of the lower box body (4 holes), but it may also be fitted inside.
A similar effect can be obtained.

〔Effect of the invention〕

As is clear from the above description, this invention has an upper box body that supports the computer body inside, and has a keyboard section and a display section mounted thereon, and the upper box body is fitted into the lower box body for vertical position adjustment.
It can be adapted to both standing work and sitting work, improving economic efficiency.

The scope of use can be expanded.

Another aspect of the present invention is that cooling air flows into the computer body and prevents dust from flowing into the computer body both when working while standing and when working while sitting on a chair, thereby eliminating failures due to dust.
