BACKGROUND OF THE INVENTION
The present invention relates to a unit shelf that collectively stores OA devices such as a server machine, a CRT monitor, a keyboard, and a mouse, and more particularly to a shelf device for mounting a keyboard, a mouse, and the like.
[0002]
[Prior art]
In recent network environments, there is a tendency to use unit shelves that collectively store OA devices such as server machines, CRT monitors, and keyboards.
[0003]
In such a unit shelf, in order to improve the operability of the keyboard, for example, as disclosed in Japanese Patent Laid-Open No. 11-155563, a keyboard mounting table (shelf plate) is provided so as to be freely drawn out and pulled out. Sometimes it is possible to tilt forward a predetermined angle.
[0004]
[Problems to be solved by the invention]
However, since the whole mounting table of the conventional keyboard is tilted forward with the rear end portion remaining in the storage portion, the entire rear end of the mounting table jumps upward greatly. For this reason, it is necessary to enlarge the dimension between a mounting base and the shelf board above it, and there exists a problem that a dead space becomes large and the height of the whole shelf becomes high.
[0005]
Also, when wiring the cable connected to the keyboard or mouse backward, it is routed along the top edge of the mounting table that jumps upward, so that every time the cable floats up or tilts the mounting table forward There is also the problem of rubbing and damaging.
[0006]
In order to eliminate the above problems, it is conceivable to reduce the front and rear dimensions of the keyboard mounting table. However, in this case, the mounting area of the keyboard, mouse, and the like is also reduced.
[0007]
The present invention was made to solve the above-mentioned problems, while ensuring a sufficient mounting area such as a keyboard, while allowing the rear end of the shelf board to be minimized and tilted forward, It is an object of the present invention to provide a keyboard placing shelf device with good operability that can prevent cable lifting and damage.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a keyboard mounting shelf device according to the present invention is provided with a guide rail facing in the front-rear direction on an upper surface of a support plate that is horizontally attached to a plurality of support columns, and a rear shelf is provided on the guide rail. The lower surface of the plate is fitted on the support plate so as to be movable in the front-rear direction and cannot be lifted, the keyboard can be placed on the support plate in front of the rear shelf plate, and the keyboard is prevented from falling on the upper surface. A front shelf having a rear end face is placed on the front end face of the rear shelf so that it can be tilted downward and movably back and forth, and the rear shelf has a predetermined front limit. When stopped at the position, the front shelf board protrudes from the front end of the support plate by a required dimension, and is held in a posture inclined forward by a required angle.
According to the shelf device configured as described above, only the front shelf on which the keyboard can be placed can be tilted forward while leaving the rear shelf on the support plate. It is possible to prevent the cables connected to the cable from being lifted up or rubbed and damaged. Further, in the housed state, the front and rear shelf boards can be used as the placement surface, so that the placement area is sufficiently ensured.
[0009]
In the shelf apparatus, it is preferable that the front shelf plate be held in a forward tilted posture by having the lower surface of the rear end portion in contact with the upper surface of the front end of the support plate.
In this way, when the front shelf is tilted forward, the trailing edge jumps to a minimum.
[0010]
In the shelf apparatus, when the front shelf plate is tilted forward, a pair of outwardly projecting protrusions at the rear ends of the pair of stop rods protruding rearward on the left and right sides are provided on the side plates on both sides of the support plate. It is preferable to contact the stop portion.
If it does in this way, since a front part shelf board will contact | abut to the stop part of the back separated from the hinge part, and it will be hold | maintained in a forward leaning attitude | position, it can be made to incline forward stably. When the lower surface of the rear end of the front shelf is also brought into contact with the upper surface of the front end of the support plate, the front shelf is more stably tilted forward because it is supported at two points above and below the hinged portion. Can do.
[0011]
In the shelf apparatus, the stop portion is preferably an upward groove portion at the front end of the guide groove formed on the side plate so as to be slidably fitted to the outward protrusion of the stop rod. .
If it does in this way, since the outward protrusion part of a stop rod slides along a guide groove, a front shelf board will not rattle up and down by vibrations, such as an earthquake.
[0012]
In the shelf apparatus, it is preferable to provide rollers that roll on the support plate at the left and right side end portions of the rear shelf plate.
If it does in this way, the back-and-forth movement of the back and front shelf will become easy.
[0013]
In the shelf apparatus, it is preferable to provide a plurality of sliders having low frictional resistance on the lower surface of the front shelf board.
If it does in this way, since sliding resistance with a front shelf board and a support board becomes small, the front and back shelf boards can be moved back and forth easily.
