Description

[Detailed description of the invention] (Field of industrial application) The present invention is a multi-stage personal computer (personal computer) that is equipped with a keyboard mounting plate on the lower tier and a mounting plate for display devices (CRT), etc. on the upper tier. This is related to a desk for business use.

(Prior Art and its Problems) Even when working on a personal computer, there are many opportunities to check materials or write notes in between keyboard operations. Conventional multi-tier computer desks are configured as computer-only desks, so it is necessary to prepare an auxiliary table separate from the computer desk that can be used as a place to store documents or as a writing workbench, or to use it as an office desk next to the keyboard. I had to use a large computer desk with a wide keyboard mount to ensure enough space was available. However, such a solution not only imposes a heavy economic burden, but also involves the inconvenience of requiring the keyboard operator to change the direction of his or her body each time, or to perform writing and checking documents in an awkward position. . Also, if you are not working on a computer, you cannot use this computer desk as a general office (study) desk unless you temporarily move the keyboard from the keyboard resting board. Even for general individual users who do not study at the same time, they have to purchase and install both a computer desk and an office (study) desk, which is not only extremely uneconomical but also reduces the use of indoor space. Efficiency is significantly reduced.

In order to solve these problems, a computer desk equipped with a foldable office work base was considered, but a conventional desk of this type was described in, for example, Japanese Patent Laid-Open No. 60-84618. As shown in the figure, an office work base plate that can be switched between a folded position where it is bent upward and a use position where it is unfolded horizontally is arranged behind a display device mounting plate that can be raised and lowered, When the office work base plate is used, the display device, etc. mounting plate is lowered, and then the office work base plate is unfolded from the folded position to the use position.

With conventional dual-purpose computer desks like this,
Not only is the structure complicated and very expensive, but it also requires a lot of effort because the display device mounting plate must be lowered to switch from using a computer to performing office work. In addition, the structure was extremely complex and impractical.

In order to solve the problems of this conventional example,
- Japanese Patent No. 172912 proposes a structure in which a keyboard table plate that can be moved back and forth is provided on the top of a fixed table. The problem is that the fixed table is extremely inconvenient to use.

In general, a keyboard table is designed to be much lower than a general office table in consideration of key typing work, and for this reason, as in the prior art mentioned above, an office table is placed at a lower position than a keyboard table with a low seating height. Providing a fixed table requires the user to perform office work in a rather unnatural posture, making it easy to get tired and making it difficult to improve office efficiency.

In addition, in conventional computer desks of this kind, the pillars that support the desk are vertically formed, so the pillars get in the way when the desk is in use, making it difficult to use.

The purpose of the present invention is to solve these problems all at once, and to provide a desk for a computer that can be used for office work and is even more convenient to use.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention has a column that slopes diagonally backward from the bottom end to the top end, and a top end from the bottom end to the top end. A lower shelf board, a keyboard mounting board, a tabletop for office work, a display device mounting board, a middle shelf board, and a top shelf board are installed so that they can each be slid back and forth independently, and among these, the office work table The plate is configured to be slidable between a use position overlapping the use position of the keyboard mounting plate and a rear retracted position protruding rearward from the display device etc. mounting plate.

(Function) According to the configuration of the present invention, when working on a computer, the office work base plate is retracted to the rear retreat position, so that the office work base plate does not interfere with the work at all. Even if you are in the middle of working on a computer, you can pull out the office work base to the use position and use the base to check documents or write on the computer. It can be done while in the working position.

In addition, the base plate for office work is formed so that it can be pulled out so as to overlap with the upper side of the keyboard resting plate, and the base plate for office work is held so as to overlap with the upper side of the keyboard resting plate. As a result, it is approximately the same height as a general office worktop, allowing you to perform office work in a natural posture without getting tired.

Further, since the office work base plate can be stored in a rear retracted position that protrudes rearward from the display device mounting plate, the office work base plate in the rear retracted position is A printer integrated with a display device mounted on a display device mounting plate,
It can be used as a holder for printed paper sent out from printers placed on the middle shelf board or the top shelf board above this.

In particular, according to the present invention, the lowermost shelf board, the keyboard mounting board, the office work base board, the display device mounting board, the middle shelf board, and the top shelf board move diagonally backward from the lower end to the upper end. Since it is installed on an inclined support, the support surface that supports the office work base on the upper side of the keyboard support plate is set back further back than the support support surface that supports the keyboard support plate. The left and right sides of the office work base plate are open, so that the supports do not get in the way during office work.

In addition, the pillars that support the lowest shelf board on the bottom side of the keyboard holder protrude further forward than the pillars that support the keyboard holder.
The computer and office accessories stored on the bottom shelf can be taken out from the front side without the bottom shelf protruding too far forward, and the left and right sides of the bottom shelf are open. Because of this, the support does not get in the way when you work on your computer or office work.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIGS. 1 and 2, 1a and 1b are a pair of left and right side frames, each of which includes a horizontal base material 3 equipped with swivel wheels (casters) 2 at both front and rear ends, and A front strut 4 and a rear strut 5 of approximately half the length are installed in parallel in a state of diagonally rearward inclination.
The lower end portions are connected to each other by a connecting rectangular frame 6, and the middle portions are connected to each other by a storage receiving box 7.

Both sides are fitted and supported so as to be slidable back and forth, and the uppermost shelf board 13 and the middle shelf board 14 are formed by side frames 1a,
The left and right sides are fitted and supported by slide rails 19 and 20 attached to the upper end and intermediate height of the front support column 4 inside 1b so as to be slidable back and forth.

The slide rail 18 that supports the display device mounting plate 12 can be installed at an appropriate angle rearward from the horizontal position (for example, in two stages at 7.5 degree intervals), and the uppermost shelf board 13 can be The mounting angle of the supporting slide rail 19 can be adjusted forward from a horizontal state to an appropriate angle (for example, in two steps at 7.5 degree intervals). Furthermore, the mounting heights of the slide rail 15 that supports the lowest shelf board 8 and the slide rail 20 that supports the middle shelf board 14 can be adjusted at appropriate intervals.

The shelf boards 8 to 10 and 12 to 14 in each stage are constructed as shown in FIGS. 3 to 5. That is, the four sides of the top plate 21 made of a rectangular metal plate are bent downward to form front and rear edges 21a, 21b and left and right edges 21c, 21d of appropriate thickness. A reinforcing material 22 is attached between both side edges 21c and 21d, and further the left and right side edges 21
A cover 23 made of plastic is externally fitted and fixed to c and 21d.

As shown in FIG. 4, the reinforcing material 22 is made by bending the four sides of the metal plate upward to form side edges 22 of an appropriate thickness.
A to 22c are formed, and the side edges 22c at both lengthwise ends are provided with fixing holes 25 that match the fixing holes 24 provided on the top plate side edges 21c and 21d. . Said top plate side edge 21c, 2

The cover 23 and the reinforcing material 22 can be fixed to the fixing holes of the top plate side edges 21c and 21d by positioning the reinforcing material 22 at a predetermined position on the bottom of the top plate 21 and fitting the cover 23 to the top plate side edges 21c and 21d. 24, the fixing hole 25 of the reinforcing material side edge 22c, and the cover 23
Since the fixing holes 27 of the two are concentrically aligned, the fifth fixing hole 27 is attached to the top plate 21 by the blind rivet 29 inserted into each fixing hole 24, 25, 27 from the cover 23 side.
It is fixed as shown in the figure. Furthermore, cover 23
Both ends of the fixing holes 26, 2 are aligned with each other.
8, fix the side edge 2 of the top plate using blind rivets, self-tapping screws, screw nuts, etc.
It can be fixed to 1c and 21d. Of course, self-tapping screws can be used instead of the blind rivets 29, and the reinforcing material 22
When installing an operation window in the holder, screw nuts etc. can also be used.

The cover 23 is slidably fitted into the slide rails 15 to 20, and
Prevents metal noise during sliding contact between each shelf board, etc. 8-10, 12-14 and the metal slide rails 15-20, and allows each shelf board, etc. 8-10, 12-14 to slide smoothly. It also helps to make things happen.

The front and rear sliding strokes of the shelves 8 to 10 that can slide back and forth are longer than the total length of these shelves 8 to 10, as shown by solid lines and imaginary lines in FIG. The stopper structure for regulating the longitudinal slide stroke limits of 1 to 10 will be explained based on FIGS. 6 to 11.

Reference numeral 30 denotes a stopper made of a spring wire, and a pair of left and right slide rails 1 that slidably support the left and right sides of the shelf boards 8 to 10.
It is attached to the lower rail material 31 of one of the rails 5 to 17 on one side. This stopper 3
0, as shown in FIGS. 10 and 11, there is a U-shaped attachment part 30a formed at the central position in the length direction so as to protrude horizontally and laterally, and a U-shaped attachment part 30a that is spaced apart from this attachment part 30a on both ends. Inverted V-shaped protrusions 30 formed to protrude upward at symmetrical positions
b, 30c, and upward hook portions 30d, 30e formed at both ends to be bent laterally, and fixed to the bottom of the lower rail material 31 at the attachment portion 30a with a screw nut 32. , both protrusions 30b, 30c are shelf boards etc. 8-10
The side pieces (cover 23) protrude upward from a pair of front and rear elongated holes 33a, 33b provided in the lower rail material 31 at the locations where the side pieces (cover 23) come into sliding contact with each other. It protrudes inside the lower rail material 31 into the moving path of the shelf boards 8 to 10.

In the stopper structure configured as described above, when the shelf boards 8 to 10 are in the rear retracted position B as shown by solid lines in FIGS. 6 and 7, the rear end upward hook portion of the stopper 30 30e is shelf board etc.8
By engaging with the lower end 34 of the front side edge 21a of the top board 8 to 10, the shelf boards 8 to 10 are prevented from moving further rearward, and the phantom line shown in FIGS. As shown, when the shelves etc. 8-10 are in the front use position A, the front end upward hook portion 30d of the stopper 30 engages with the lower end 35 of the top rear side edge 21b of the shelves etc. 8-10. This prevents the shelf boards 8 to 10 from moving further forward.

When the shelves 8 to 10 in the use position A or the retracted position B are moved backward or forward, the sides and bottom surfaces of the shelves 8 to 10 (the bottom surface of the cover 23 ) is an inverted V of stopper 30
By pressing down the square-shaped protrusions 30b and 30c, the stopper 30 is deflected downward against elasticity about the attachment part 30a, so that the upward hook parts 30d and 30e at both ends are placed under the movement path of the shelves 8 to 10. escape to. Therefore, the shelves 8 to 10 can be slid back and forth without coming into contact with the hooks 30d and 30e. And shelves etc. 8~
10 crosses the area between the pair of inverted V-shaped protrusions 30b and 30c at the front and rear of the stopper 30, the stopper 30, which had been deformed by being pressed against the protrusions 30b and 30c, elastically returns, and the rear end is hooked upward. The portion 30e is the lower end 3 of the front side edge 21a of the top plate of the shelves 8 to 10 that have reached the rear retraction position B.
4, and the front end upward hook portion 30d engages with the lower end 35 of the top rear side edge 21b of the shelf boards 8 to 10 that have reached the front use position A.

The computer desk configured as above is
For example, the keyboard 36 is placed on the keyboard mounting plate 9.
A display device (CRT) 37 is placed on the display device etc. placement board 12, a personal computer, a floppy disk drive device, etc. 38 is placed on the middle shelf board 14, and the top shelf is placed. A printer 39 can be placed on the shelf board 13. Of course, the example of use is not limited to this, and for example, a display device 37 and a personal computer, a floppy disk drive device, etc. are placed on the display device mounting plate 12, and a printer 39 is placed on the middle shelf board 14. It can be used as appropriate depending on the situation, such as placing paper supplies or placing a personal computer, floppy disk drive device, etc. 38 on the lowermost shelf board 8.

In any case, when working on a computer, the keyboard mounting plate 9 is pulled out to the front use position A, and the office work base plate 10 is moved back to the rear retreat position B, as shown by the solid line in FIG. . or,
The lowest shelf board 8 is placed so that it does not get in the way of the workers' feet.
is also moved back to the rear evacuation position B. When loading or unloading articles into or from the storage box 7, the upper part of the storage box 7 can be opened by retracting the keyboard mounting plate 9 to the rear retreat position B.

Furthermore, when checking documents or writing while working on a computer, the office work base plate 10 is pulled out from the rear retreat position B to the front use position A, leaving the keyboard rest plate 9 in place, so that it overlaps the keyboard 36. Necessary work can be performed on the base plate 10. When using this computer desk as an office (study) desk, the office work base plate 10 is pulled out to the use position A, and the keyboard mounting plate 9 is retreated to the rear retreat position B.
It is also possible to use a wider space under the base plate 10.

When working on a computer, the office work base plate 10 is retracted to the rear retracted position B, but the position at this time is such that it protrudes further rearward than the display device mounting plate 1, as shown in FIG. With this configuration, the office work base plate 10 located at the retracted position B can be used as a receiving tray for printed sheets sent out from the printer 39.

In the above embodiment, the keyboard mounting plate 9 was configured to be slidable back and forth in the same manner as the office work base plate 10 due to its relationship with the storage receiving box 7. However, if there is no relationship with the storage receiving box 7, The keyboard mounting plate 9 may be fixed at the use position A. Further, a locking device for fixing the shelf boards 8 to 10, 12 to 14, which are slidable back and forth, at least at the limits of the back and forth sliding strokes can also be used. Of course,
The shelf boards 8, 13, 14 and the storage box 7 are not essential to the present invention and can be omitted. Further, sliding the display device or the like on the mounting plate 12 back and forth and adjusting the angle are not essential conditions.

(Effects of the invention) As described above, according to the invention, a bottom shelf board, a keyboard mounting board, an office work base board, a display device mounting board, a middle shelf board, and a top shelf board are installed on the support. Each structure is constructed so that it can slide forward and backward independently, so you can work efficiently on your computer by placing the printer on the top shelf and placing the computer or floppy desk drive unit on the middle shelf. The workability is excellent because the above-mentioned plates can be slid back and forth according to the working conditions.

Further, according to the present invention, the base plate for office work is
Since the keyboard is formed so that it can be pulled out to the usage position that overlaps the usage position of the keyboard resting board, the keyboard can be placed on the keyboard resting board when checking materials or writing while working on a computer. By pulling out the office work base while keeping it in place, office work can be done easily and efficiently, and writing work while working on a computer can be done easily without changing the direction of the body.

In particular, it is characterized in that the base plate for office work is formed so as to be drawn out so as to overlap with the upper side of the keyboard mounting plate. In other words, the keyboard rest plate is generally formed lower than a general office work base, so by holding the office work work base so as to overlap the upper side of the keyboard rest, it is possible to hold the office work work base so that it overlaps with the upper side of the keyboard rest board. The base plates are at approximately the same height, allowing office work to be done in a natural posture without tiring, and from this point of view it is also practical.

Furthermore, according to the present invention, the office work base plate:
Since it can be stored in a rear retracted position that protrudes rearward than the display device mounting plate, the office work base plate in the rear retracted position is
Use it as a holder for printed paper sent out from a printer integrated with a display device placed on the display device mounting board, or a printer placed on the middle or top shelf above this. It is possible,
From this aspect as well, you can easily work on your computer.

Particularly, according to the present invention, the lowermost shelf board, the keyboard mounting board, the office work base board, the display device mounting board, the middle shelf board, and the top shelf board move diagonally backward from the lower end to the upper end. Since it is installed on a tilting support, the support surface that supports the office work base on the upper side of the keyboard support plate is set back further back than the support support surface that supports the keyboard support plate. The left and right sides of the office work base plate are open, so that the supports do not get in the way during office work, and office work can be easily performed from these sides as well.

In addition, the pillars that support the lowest shelf board on the bottom side of the keyboard holder protrude further forward than the pillars that support the keyboard holder.
The computer and office accessories stored on the bottom shelf can be taken out from the front side without the bottom shelf protruding too far forward, and the left and right sides of the bottom shelf are open. Because of this, the support does not get in the way when working on computers or office work, making it even more convenient to work with.
