2. Description of the Related Art In general, a general rack of this kind is not specifically shown, but simply mounts a mounting plate for mounting a monitor or a keyboard horizontally between four columns with bolts or the like. It has a relatively simple configuration. Therefore, under a conventional rack, a monitor such as a personal computer is directly mounted on the mounting plate fixed horizontally, and the monitor screen in the mounted state is inevitable. Then, while maintaining a substantially vertical posture, the operator faces the operator's face.

[0003]

Therefore, when operating a personal computer or the like, the operator must maintain the vertical position and alternately look at the screen of the monitor facing the user and the keyboard at hand. Naturally, the user is forced to shake his or her head up and down, and this causes a considerable burden on the operator's neck, shoulders and hips, especially during long-time operation. Further, the fact that the screen of the monitor faces the operator's face directly causes the operator's line of sight to naturally approach the screen side of the monitor, which causes fatigue of the operator's eyes. In this way, with conventional racks, the longer you engage in operations for a long time, the more the neck, shoulders, and hips may be burdened, and eyestrain may be caused, resulting in a loss of operator health. there were.

SUMMARY OF THE INVENTION The present invention has been developed in view of such circumstances, and has at least 4
A rack having a monitor mounting plate and a keyboard mounting plate between two columns, wherein the front end of the monitor mounting plate is swingably connected to a cross member spanned between two opposed front columns. At the same time, a pair of operating rods are movably provided on the left and right sides of the bottom of the monitor mounting plate to elastically urge the respective operating rods outward to be separated from each other, and each of the operating rods is provided at the rear of the monitor mounting plate. An operating lever is provided for moving the operating rod inward toward each other against the elastic biasing force, and a plurality of locking holes for locking the outer ends of the operating rods are provided between the left and right supporting columns. A pair of side panels is provided, and the outer end of each operating rod is locked in one locking hole of the corresponding side panel by swinging of the monitor mounting plate accompanying the operation of the operation lever. The monitor mounting plate at the desired tilt angle. It adopted a configuration that can be decided.

Therefore, according to the present invention, by operating the operating lever, the pair of operating rods are temporarily moved inward toward each other against the elastic urging force, and the outer end of each of the operating rods is moved. While removing the parts from the locking holes of the corresponding side panel, swing the rear side of the monitor mounting plate, and lock the outer ends of the pair of operating rods again to any locking holes of the side panel. This allows the monitor mounting plate to be positioned at a desired tilt angle. Therefore, the screen of the monitor placed on the mounting plate can also be set according to the positioning angle of the mounting plate, so that the operator can operate the personal computer under the operating environment most suitable for him. And the like.

Forming a plurality of bolt holes 6 for fixing;
A plurality of bolt holes 7 for fixing a crosspiece 31 of a monitor mounting plate 30 to be described later via a bracket 33 are formed in the inner surface of the intermediate portion of each front support 2a, and the lower inner surface of each front support 2a and each rear A plurality of bolt holes 8 for fixing the bent flanges 5c of the pair of side panels 5 are formed at the same pitch on the inner surface of the column 2b near the intermediate portion.
In the figure, 9 is a carrier, 10 is a caster, and 11 is a stopper leg.

As is apparent from FIG. 2, similarly, the keyboard mounting plate 20 has L-shaped brackets 21 fixed to the left and right side surfaces thereof with bolts 22. The tip of each L-shaped bracket 21 is connected to a pair of L-shaped brackets 21 by a pair. Pivotally supported on the bracket 24 via the pin 23,
By fixing each bracket 24 to the left and right front supports 2a via the above-described bolt holes 6 and bolts 25, a transition is made between a horizontal expanded state and a vertical folded state outside the intermediate portion between the left and right front supports 2a. It has a configuration that can be used.

A cylindrical member 26 is welded to the pair of brackets 24 on the side surface located inside the rack body 1, and a triangular support member 27 is rotated on each of the cylindrical members 26. If possible, this support member 27
When the is rotated outward, the lower surface of the keyboard mounting plate 20 is supported, and its horizontal deployment state is reliably maintained. Conversely, when it is rotated inward, the vertically folded state of the keyboard mounting plate 20 is changed. It has a configuration that can be guaranteed.

The monitor mounting plate 30 has a front end connected to a crosspiece 31 via a long hinge 32, and
Are fixed to the bolt holes 7 formed on the inner surface of the above-described front column 2a via bolts 34, so that the bracket 33 is welded between the front columns 2a inside the rack body 1. With the crosspiece 31 as a fulcrum,
The rear side is configured to be swingable.

As shown in the figure, the monitor mounting plate 30 itself has a folded wall 35 continuous on both left and right sides and a rear part thereof.
And a fence 37 made of a punching board provided with a plurality of monitor holders 36 is provided in the rear half of the folded wall 35. In particular, the monitor mounting plate 30
When the monitor is tilted, a configuration is also adopted to prevent the monitor from falling or moving backward.

In addition to this, in the present embodiment,
As shown in FIG. 3, cylindrical members 45 are welded to the left and right sides of the bottom of the monitor mounting plate 30, and a pair of operating rods 40 are movably fitted into the respective cylindrical members 45. A coil spring 47 for urging the operating rod 40 outward is provided between the front end flange 46 and the outer end surface of the corresponding cylindrical member 45, while the rear side fence 3 is mounted.
A handle portion 4 having a pair of cylinder members 44 provided on the seven surfaces, and an operation lever 42 connected to the inner end portions 40 a of the pair of operation rods 40 by metal wires 41 on the respective cylinder members 44.

The connected state is maintained.

The operating lever 42 is provided with guide rings 42a at both ends thereof to be fitted to both arms of the handle portion 43, and each guide ring 42a is provided on both arms of the handle portion 43. Although it is configured to be able to move in the front-rear direction inside the handle portion 43 by the guide, in a normal state, it moves toward the fence 37 by the spring pressure of the coil spring 47 described above.

The side panel 5 has a pair of bent flanges 5c formed with through holes 5b corresponding to the bolt holes 8 of the front and rear support columns 2a and 2b, and an outer end portion 40b of the operating rod 40 in a width region thereof. Are formed with a plurality of locking holes 5a for locking at regular intervals. It is assumed that the plurality of locking holes 5a are located on the swing locus of the rear end of the monitor mounting plate 30. Therefore, when the position of the crosspiece 31 of the monitor mounting plate 30 is changed in the vertical direction by selecting the bolt hole 7 between the two front supports 2a, the front and rear supports 2a. The position of the side panel 5 must be changed by selecting the bolt hole 8 of 2b.

Therefore, below the rack according to the present embodiment, as shown in FIGS.
When the monitor mounting plate 30 is locked in the uppermost locking hole 5a of the side panel 5, the monitor mounting plate 30 is set to be in a horizontal state for the time being. When it is desired to adjust the angle of the screen of the monitor M on the mounting plate 30 by inclining the mounting plate 30, first, securely grip the handle portion 43 with both hands,
As shown in FIG. 6A, when the user puts a finger on the operation lever 42 and pulls the operation lever 42 forward, the pair of operating rods 40 connected by the metal wire 41 interlock with Since the springs 47 move inward toward each other against the elastic urging force of the spring 47, the outer ends 40b of the operating rods 40 are moved to the uppermost position of the side panel 5 as shown in FIG. It will come off from a certain locking hole 5a.

Therefore, the rear portion of the monitor mounting plate 30 can be lowered downward with the cross member 31 as a fulcrum, while holding the handle portion 43 securely in this state and suppressing a sharp drop. For example, the monitor mounting plate 30 can be smoothly swung while the monitor M is mounted.

Then, while swinging the rear side of the monitor mounting plate 30 downward, the locking hole 5a of the side panel 5 is arbitrarily selected, and at the position of the selected locking hole 5a, When only the operating lever 42 of the gripped handle portion 43 is released, the pair of operating rods 40 connected by the metal wire 41 are automatically moved in the outward direction separated from each other by the elastic biasing force of the coil spring 47. Then, the outer end portion 40b of each of the operating rods 40 is again locked in the selected locking hole 5a. As a result, as shown in FIG. Is positioned at the desired tilt angle together with the monitor M. In addition, when it is desired to repeatedly adjust the tilt angle, the tilt angle can be freely adjusted by performing the above-described operation again.

[0019]

As described above, according to the present invention, by adopting the above configuration, the monitor mounting plate can be positioned at a desired tilt angle, so that the monitor mounted on the monitor mounting plate can be positioned in the tilted state. When used with the monitor, the monitor screen will be positioned below the front of the operator's face at the desired angle of inclination, so even if the monitor screen and the keyboard at hand are alternately viewed, only the movement of the line of sight Since it is not necessary to swing the head up and down, not only does the operator's neck, shoulders and waist not only be considerably burdened, but also the distance between the monitor screen and the operator's eyes will be naturally separated, This also reduces operator eye fatigue. In addition, since the operation of tilting the monitor mounting plate can be performed by operating the operation lever while the monitor is mounted, a troublesome operation is not required, and the operation can be performed simply and safely by one person.
