[0002]

2. Description of the Related Art Japanese Utility Model Laid-Open No. 5-30924 discloses a computer desk shown in FIG. 12 (hereinafter referred to as "conventional computer desk"). In a conventional computer desk, a computer display 1 and a first reflector 3 are arranged inside the desk, and a top plate 5 of the desk is provided with a top plate opening 7. The second reflection plate 9 is pivotally attached to the upper and lower sides via a rotation shaft 10 so as to be freely rotatable in the vertical direction. When a computer is used, the second reflection plate 9 in the top plate opening 7 is rotated upward to stand up. This allows the user of the computer to display the screen of the display 1 with these two reflectors 3,
9, when the computer is not in use, the second reflector 9 in the top plate opening 7 is turned downward to lie down, so that the second reflector 9 closes the top plate opening 7. The top plate 5 is closed so that it can be used as a normal desk having neither openings nor protrusions.

Japanese Utility Model Laid-Open No. 59-160330 discloses another computer desk (hereinafter referred to as "conventional computer desk"). Conventional computer desks have a top plate opening on the desk top and a display that can be moved up and down by an up-down mechanism. When the computer is not in use, the display is lowered by the up / down mechanism to be stored inside the desk.

Japanese Utility Model Laid-Open No. 4-28327 discloses another computer desk (hereinafter referred to as "conventional computer desk"). Conventional computer desks are provided with a top plate opening on the top of the desk and a display that is rotatable up and down. When the computer is not in use, the display is turned downward to be stored inside the desk.

[0005]

In the above-mentioned conventional computer desk, the second reflection plate 9 of the top plate opening 7 is rotatable vertically in the top plate opening 7 via a rotating shaft 10. Therefore, the top plate needs to be provided with a top plate opening having a size corresponding to the size of the second reflection plate. Then
It is necessary to use a second reflector having a sufficient size in terms of usability and the like, so that the top plate opening must be enlarged. If the opening of the top plate becomes large, there arises a problem that a space on the top plate for placing a keyboard, documents, and the like becomes small.

[0006] In the above-mentioned conventional computer desk, there is a problem that a rigidity of the desk itself must be increased because a mechanism for raising and lowering the display is required. In addition, since the display is stored inside the desk when the computer is not used, the space for the feet is small for users who use the display less frequently or who do not use the display for a long time. However, there is also a problem that the desk is not easy to use.

Further, conventional computer desks,
However, since the display, the means for rotating the second reflector, the mechanism for raising and lowering the display, and the like are integrally incorporated in the desk, there is a problem that the degree of freedom in designing the desk itself is low.

The present inventor has proposed a conventional computer desk,
In order to solve the above-mentioned problems in Japanese Patent Application Laid-Open No. 261335/1996 (unpublished), the following computer desk (hereinafter referred to as a “filed computer desk”) is proposed.

That is, the computer desk for which the application has been filed is shown in FIG.
As shown in FIG. 0, the desk 11 includes a support unit 13 that is separate from the desk 11, and the top plate 15 of the desk 11 is provided with a top plate opening 17 that can be closed (closed). The support unit 13 can be stored below the top plate 15 of the desk 11, and the support unit 13 has a first reflector 25 and a second reflector 27 on which a display 23 of a computer is placed. The second reflecting plate 27 is made to be able to come and go with respect to the top plate opening 17 of the desk 11.

In the computer desk for which the application has been filed, two rotating arms 33 and 35 are connected to each of the rotating arms 33 so that the second reflecting plate 27 can be freely moved in and out of the top plate opening 17 of the desk 11. , 35 are pivotally attached to the support unit 13 at one ends 33a, 35a, respectively, so as to be rotatable in the vertical direction, and the other ends 33b, 35b of the respective rotating arms 33, 35 are pivoted to the second reflection plate 27, respectively. I'm wearing

In the computer desk of the present invention, the vertical angle of the second reflector 27 is adjusted when the second reflector 27 is projected upward from the top plate opening 17 of the desk 11. In order to be able to perform the rotation, a long hole 34 is formed at the one end 35a of one of the rotation arms 35, and the rotation shaft 36 of the rotation arm 35 protruding from the support unit 13
Is inserted into the long hole 34 (see FIG. 10). In this case, the rotating arm 3 is rotated without rotating the rotating arm 33.
3 with the other end 33b as the center of rotation.
Is slightly rotated in the vertical direction so that the second reflector 2
7 can be adjusted in the vertical direction.

In the computer desk for which the application has been filed, in order to stabilize the second reflecting plate 27 when the second reflecting plate 27 is protruded above the top plate opening 17 of the desk 11, two rotating arms 33 and 35 are used. At least one of the rotating arms 3
Fixing means 38 is provided for fixing 3 at its top dead center. As shown in FIGS. 10 and 11, the fixing means 38 is a latch mechanism including a pair of latch components 38a and 38b, and one of the latch components 38a is attached to the upper end of the support unit 13 via the attachment member 40. , The other latch component 38 b is connected to the one rotating arm 3.
Attach to 3. These latch components 38a, 38
b is mutually detachable.

In the computer desk for which the application has been filed, the first reflecting plate 25 has its lower end pivotally attached to the support unit 13 and is rotatable outward (in the direction of the arrow in FIG. 10) with respect to the support unit 13. It is. The reason why the first reflecting plate 25 is rotatable outward with respect to the support unit 13 is that the first reflecting plate 25 becomes dirty when the first reflecting plate 25 is contaminated with dust or the like.
This is because the first reflecting plate 25 can be easily cleaned after the outer surface of the first reflecting plate 25 can be easily reached by rotating the outer surface 5.

Incidentally, it has been found that the following problems have been encountered in the computer desk for which the application has been filed. That is, in the computer desk for which the application has been filed, two rotating arms 3 are provided.
One of the rotating arms 33 of the pair 3 and 35 is moved by a latch mechanism including a pair of latch members 38a and 38b.
The pivot arm 33 is fixed at the top dead center. However, when the fixation of the pivot arm 33 is released, the second reflection plate 27 is lifted so that the latch component 38
It is necessary to perform an operation for releasing the engagement between a and 38b. That is,
When the fixing of the rotating arm 33 is released, the second reflecting plate 2
It is a great need to lift 7. Also, when an upward force is applied to the one rotating arm 33 when adjusting the vertical angle of the second reflecting plate 27, the engagement of the latch components 38a, 38b is performed against the will of the user. There is also the problem of being canceled. Further, there is also a disadvantage that the angle of the first reflecting plate 25 cannot be adjusted in the computer desk for which the application has been filed. Further, in the computer desk for which the application has been filed, there is a disadvantage that the first reflector 25 is at the foot even when the computer is not used, and the space at the foot is narrowed.

In view of the above, the present invention has been made to solve the above-mentioned problems in the conventional computer desk and also to solve the above-mentioned problems in the computer desk of the present invention. .

[0022]

[Action]

[Desk of Computer of Claim 1] A desk and a support unit are separate bodies, and each is manufactured separately. The support unit is always stored below the tabletop. When using the computer, the user pivots the two pivot arms upward to cause the second reflection plate to protrude above the opening of the top plate of the desk, and the screen of the display to the first and second screens. It can be seen through the reflector. When you are not using your computer,
By rotating the two rotating arms downward, the second reflector is immersed below the top plate opening, and the top plate has no openings or protrusions by closing the top plate opening. Can be Since the four pivot link mechanism is formed by the two pivot arms, the support unit, and the second reflector, the second reflector is driven by the display or the first reflector as the two pivot arms rotate. It rotates up and down in a state where the angle is regulated so as not to come into contact with the reflection plate. When the computer is not used for a long time, the support unit can be separated from the desk. The above points are the same as those of the computer desk for which the application has been filed.

According to the computer desk of the first aspect, when the second reflecting plate is projected upward from the top plate opening of the desk by rotating the two rotating arms upward, The cam latch pivotally attached to the upper pivot arm pivots by its own weight, and its locking portion is locked to the holder of the support unit. Therefore, the upper turning arm is locked, and the second reflector is stabilized in use. The upper rotating arm of the two upper and lower rotating arms cannot move forward and backward with respect to the supporting unit, and the lower rotating arm can move forward and backward with respect to the supporting unit. The second reflecting plate protruding upward can finely adjust the angle in the vertical direction about the other end of the upper rotating arm as the center of rotation. At this time, if the vertical rotation angle of the second reflector is within a certain range, the moving distance of the lower turning arm is also within a certain range, and the lower reflecting arm projects. Since the provided pin does not release the lock of the cam latch with the holder, the lock of the upper rotating arm by the cam latch and the holder is not released. When the second reflector is vertically rotated beyond a certain angle about the other end of the upper rotation arm as a rotation center, the lower rotation arm moves beyond a certain range, The pin pushes and rotates the cam latch, and the locking portion of the cam latch comes off the holder. Therefore, at this time, the lock of the upper rotating arm by the cam latch and the holder is released. In other words, by rotating the two rotating arms downward, the second reflector can be immersed below the top plate opening.

According to a second aspect of the present invention, the first reflector can be fixed at an arbitrary vertical angle as required. By adjusting the vertical angle of the first reflector, the user can increase the foot space if necessary, or adjust the virtual image angle of the display screen with respect to the eyes as described later to reduce image distortion. Can be eliminated.

When the support pin is fitted in any of the recesses of the groove, the hood cover cannot rotate and the first reflector is fixed at the angle. Become. When adjusting the vertical angle of the first reflector, the hood cover is pivoted vertically by lifting the hood cover slightly upward to remove the support pins of the support unit from the recesses of the groove. Then, the support pin may be fitted into another concave portion of the groove again.

[Claim 4] A groove in the hood cover when an external force is applied to the hood cover, for example, when the user accidentally kicks up the hood cover or the first reflector with a foot. The gentle concave portions easily pass over the support pins of the support unit, and the hood cover is easily turned up and down. In other words, when an external force is applied to the hood cover, the hood cover can easily escape. Therefore, the first reflector is prevented from breaking in the case described above.

According to a fifth aspect of the present invention, if the first reflector is housed in the support unit, a sufficient foot space can be ensured when the computer is not used.

【The invention's effect】

[Computer Desk of Claim 1] In the computer desk of claim 1, since the desk and the support unit are separate bodies, the degree of design freedom of the desk itself is increased. In addition, the standard of the support unit can be shared for various desks. Therefore, it is possible to reduce the manufacturing cost of the support unit. Further, when the computer is not used for a long time, by separating the support unit from the desk, a large space below the top plate in the desk can be secured, and the usability as a normal desk can be further improved.

Since the second reflecting plate is made to protrude and retract from the top plate opening of the desk by rotating the rotating arm in the vertical direction, the second reflecting plate is placed in the opening of the top plate of the desk. On the other hand, the mechanism for retracting and retracting is simple, and is configured with a small number of parts. Therefore, it is possible to reduce the manufacturing cost of the computer desk. Further, since the second reflecting plate is projected upward from the top plate opening of the desk by rotating the rotating arm upward, the vertical angle of the second reflecting plate can be adjusted. The top plate opening can be made smaller than the conventional computer desk in which the second reflection plate is pivotally attached to the top plate opening in the up-down direction via a rotation shaft.

Further, since a four-bar link mechanism is formed by the two rotating arms, the support unit, and the second reflecting plate, the second reflecting plate is moved with the rotation of the two rotating arms. It rotates up and down in a state where the angle is regulated so as not to come into contact with the display or the first reflection plate.

Although the above is an effect common to the effects of the above-mentioned computer desk, the computer desk of claim 1 exhibits the following effects not found in the above-mentioned computer desk. When the second reflecting plate is projected above the opening of the tabletop of the desk by rotating the two rotating arms upward, the cam latch mounted on the upper rotating arm holds the holder of the support unit. , The upper turning arm is locked, and the second reflector is stabilized in use. The angle of the up-down direction can be adjusted in a state where the second reflection plate is projected above the opening of the top plate of the desk. At this time, if the vertical rotation angle of the second reflector is within a certain range,
The lock of the upper rotating arm by the cam latch and the holder is not released. By rotating the second reflecting plate vertically beyond a certain angle, the lock of the upper rotating arm by the cam latch and the holder is released, and by rotating the two rotating arms downward, The second reflector can be immersed below the top plate opening. That is, when the vertical angle of the second reflector is adjusted, if the rotation angle is within the normal use range, the lock of the upper rotation arm is not released, and the rotation angle is not released. Since the lock of the upper turning arm is released only when the distance exceeds the normal use range, the lock of the upper turning arm is not released against the intention of the user. Also, since it is not necessary to lift the second reflector upward when unlocking the upper rotating arm,
No great force is required to release the lock.

According to a second aspect of the present invention, the first reflector can be fixed at an arbitrary angle in the up-down direction as required, so that the angle of the first reflector in the up-down direction is adjusted. Accordingly, the user can increase the space under the feet as needed, or adjust the virtual image angle of the display screen with respect to the eyes to eliminate image distortion.

According to a third aspect of the present invention, the first reflector can be easily and reliably fixed at an arbitrary angle in the vertical direction.

In the case where the user accidentally kicks up the hood cover or the first reflection plate with his / her feet, the hood cover easily escapes. The plate is prevented from breaking.

According to a fifth aspect of the present invention, if the first reflecting plate is housed in the support unit, a sufficient foot space can be secured when the computer is not used.
