Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a multifunctional desk to which other functions are added, not only for office use.

(Conventional technology and problems to be solved) With the recent development of OA (office automation) equipment, in line with the demand for carrying out office work while operating OA equipment by mounting OA equipment on an office desk. A desk is desired.

In order to meet such requirements, a board that can be pulled out in the horizontal direction is stored in the bottom of the top plate of the desk, and a computer keyboard or the like is placed, or a CRT display is stored in the desk. It has been proposed that it can be exposed on the desk when necessary.

However, there is a problem that it is difficult to use as an office desk when OA equipment such as a computer is mounted on the desk and used, and two such desks are arranged face to face. In this case, since there is only a shield (partition) corresponding to the height of the CRT display between the two facing each other, there arises a problem that the line-of-sight of each other is disturbed and the work efficiency is lowered.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a multi-functional desk having a plurality of functions such as an office automation device and a partition function in addition to the office function.

[Structure of the Invention] (Means for Solving the Problems) The basic structure of the present invention for solving the above problems is that the lower end portion of the board is detachably fitted and held, and the bottom surface becomes a concave portion in the central portion and the upper surface becomes A moving frame provided with a protruding portion that is a convex portion, a lead nut fixed via a mounting plate from a concave portion of the bottom surface of the central protruding portion of the moving frame, a lead screw screwed to the lead nut, and the lead screw It is composed of a motor for rotating and driving.

The board contains a liquid crystal panel and a liquid crystal drive circuit for driving the liquid crystal panel.

Further, the board is housed in a region where the display is different from that of the case.

The board is a white board.

(Operation) The lower end of the board is detachably fitted and held on the moving frame so that the board provided as a partition behind the desk can be replaced with a board having another function. The moving frame moves up and down by fixing the lead nut through the mounting plate from the concave portion of the bottom surface protruding in the center and rotating the lead screw screwed to the lead nut by the motor. In addition, since it is fixed to the lead nut from the recess on the bottom of the central protruding portion of the moving frame via the mounting plate, the amount of exposure of the board when the central protruding upper surface of the moving frame is at the same position as the bottom surface of the top plate Can be maximized to maximize the stroke of the board up and down movement.

Further, the board, which houses a liquid crystal panel and a liquid crystal drive circuit for driving the liquid crystal panel, can be fitted to the moving frame.

In addition, the board, in which the display and the storage case are accommodated in different areas, can be fitted to the moving frame.

Also, the board may be fitted as a white board to the moving frame.

(Example) Hereinafter, the present invention will be specifically described with reference to examples.

FIG. 1 is a perspective view showing an embodiment of the present invention. A desk body 1 is provided with a cover 1B that opens and closes in the direction of the arrow in the figure at the rear end 1A of the top plate, and a board 2 is accommodated inside the cover 1B in an open state. This board 2 has a plate shape slightly smaller than the top plate, and
The board has a thickness equal to or slightly thicker than that of the top board, and is accommodated in a standing position in the back of the desk in a direction intersecting with the top board. The fixed frame 3 attached to the bottom bottom of the desk has the above board. A drive mechanism is mounted to drive 2 to move upward to expose the standing legs on the top plate or to return it to its original position. Therefore, the board 2 is driven by this drive mechanism so as to project and retract in the arrow direction as shown by the chain line. A switch 2A for operating the drive mechanism is provided on the upper end surface of the board 2.

Next, the drive mechanism of the board 2 will be described with reference to FIG. 2. In FIG. 2, reference numeral 4 is a moving frame, which has a U-shaped cross section, and the front shape is substantially mountain-shaped. . The entire length of the moving frame 4 is close to the width of the desk, and the lower end of the board 2 is fitted and held in the U-shaped groove. The left and right ends 4A of this moving frame 4,
Guide mounting plates 5A and 5B are attached to the respective 4B so as to project to the inner side, and guide protrusions 6 extending outward are formed in upper and lower two stages on each mounting plate. Then, guide rails 7A and 7B having a U-shaped cross section are provided on both sides of the moving frame, and the guide projections 6 are vertically movably engaged with the guide rails. The guide rails 7A and 7B are fixed to both side walls of the desk.

A mounting plate 8 is mounted in a recess 4C in the center of the moving frame 4, and its tip projects forward. The protruding tip of the mounting plate 8 is fixed to the lead nut 9. A lead screw 10 is screwed onto the lead nut 9. The upper end of the lead screw 10 is fixed to the upper wall surface of the desk, and the pulley 11 is fixed to the lower end thereof. The pulley 11 is connected via a belt 12 to a pulley 13 attached to the rotating shaft of a motor 14. The lower end of the lead screw 10 and the shaft end of the motor 14 are rotatably mounted on the frame 3 which is horizontally mounted on the bottom surface of the desk.

According to the drive mechanism described above, the rotation of the motor 14 causes the lead screw 10 to rotate and move the lead nut 9 upward or downward. As a result, the moving frame 4 connected to the lead nut 9 moves up and down. At this time, the moving frame 4 smoothly moves along the left and right guide rails. The board 2 held by such a moving frame 4 is exposed upward from the top surface of the top plate and stands in a direction intersecting the top plate surface. It should be noted that, when the standing leg of the board 2 is exposed, the maximum exposed position is reached when the central projecting upper surface of the moving frame 4 is at the same position as the bottom surface of the top plate. By thus providing the concave portion 4C on the central bottom surface of the moving frame 4 and attaching the mounting plate 8 to the concave portion 4C, it is possible to maximize the stroke of the vertical movement of the board. That is, it is possible to make the height of the board 2 at the time of exposure approximately twice the height of the desk.

Next, various functions of the board 2 will be described with reference to FIGS. 3 to 5.

In FIG. 3, the liquid crystal panel 15 is housed on the substantially entire surface of the board 2, and the operation button 16 is attached to one part. A liquid crystal drive circuit is housed inside. The bottom surface of the board 2 is formed in the same shape as that of the moving frame 4 so that they can be closely fitted to each other.

In the board 2 shown in FIG. 4, the liquid crystal display 17 is accommodated in one area, the accessory case 18 is accommodated in the other area, and the operation button 19 is provided at the end portion.

The board 2 shown in FIG. 5 is a white board 20 on substantially the entire surface thereof, and an accessory case 21 for accommodating a marker pen or the like is provided on the lower surface thereof.

By fitting and holding one of the boards 2 as described above in the moving frame 4 as described above, this desk is used for office work, and when necessary, the board is exposed by standing to form a liquid crystal panel. Alternatively, it can be used as a display and further as a whiteboard. At the same time, when it is used as a partition between operators, since it has a sufficient height, it can completely block the field of view.

The present invention is not limited to the above embodiment, and various modifications can be made.

For example, the combination of the pulley and the belt in the drive mechanism may be replaced with the combination of the gear mechanism.

[Advantages of the Invention] The desk can be used for office work, the standing legs can be exposed as a partition if necessary, and the board can be detachably fitted and held on the moving frame, so that it can be exchanged with various boards. In addition, because it is configured so that the amount of movement of the moving frame can be increased relative to the height of the desk
The board can be used effectively.

Further, by replacing the board with a board provided with a liquid crystal panel, a television image or the like can be displayed.

Also, by replacing the board with a display provided, an OA device such as a personal computer or a word processor can be operated.

Also, by replacing the board with a white board, it is possible to record a meeting and post a schedule.
