Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary table that can be stored in a personal computer rack or the like, and has a particularly simple structure that enables stable loading and unloading.

[0002]

2. Description of the Related Art Conventionally, in a frame body assembled by a vertical frame extending vertically and a horizontal frame extending horizontally,
2. Description of the Related Art There is known a personal computer rack in which a top plate serving as a workbench and a shelf plate are installed in different steps so that a personal computer and peripheral devices can be placed. As one of the racks of this type, there has been proposed one in which a small table is attached so as to be able to be stored under the top plate so that it can be used as an auxiliary table for sliding a mouse which has been widely used in recent years as an auxiliary input device. There is.

For example, as shown in FIG. 7A, a pair of guide rails (b) having a substantially S-shaped cross section are formed on the lower surface of the top plate (a).
The table rail (b) is held by the guide rail (b) so that it can slide. When not in use, the table board (c) is stored to eliminate the protrusions around the top panel, while at the time of use The table plate (c) is pulled out in the guide rail direction by a desired length so that it can be used as an auxiliary table for a mouse. As for the pulling-out direction, there are a pulling-out method in the front direction of the operator and a pulling-out method in the lateral direction.

[Problems to be Solved by the Invention]

However, as shown in FIG. 7B, a thinner top plate (a) is continuously provided inside the horizontal frame (d) so that the upper surfaces of both (d) and (a) are aligned. Sometimes
Even if the gap between the horizontal frame (d) and the table plate (c) is reduced as much as possible, the lower surface of the top plate (a) and the table plate (c)
When the table plate (c) is pulled out, the tip end swings in the direction of the arrow around the end (e) of the guide rail (b) as a fulcrum when the table plate (c) is pulled out. The usability of was greatly impaired.

In order to solve such a problem, conventionally, for example, as shown in FIGS. 8 (A) to 8 (C), a long hole (F) is formed on the table supporting surface of a guide rail (B) having a substantially S-shaped cross section. It is proposed that a locking tool (g) with a bulged head is attached to the lower surface of the table plate (c) placed on this with the elongated hole (f) inserted. Has been done. That is, the locking tool (g) is locked on the lower surface of the guide rail (b), and is supported so that the end of the table plate (c) does not float up. However, since the auxiliary table according to the above-described structure has a structure in which the locking tool (g) is attached to the table plate (c) through the elongated hole (f), it takes time to install the table and the manufacturing cost increases. There was also the problem of doing.

By the way, in the case of the auxiliary table that is pulled out in the lateral direction, considering the usability of the mouse, the auxiliary table is pulled out to the right side of the tabletop for right-handed persons and to the left side of the tabletop for left-handed persons. Is ideal. However, the conventional auxiliary table has a structure in which if the pull-out direction is determined at the time of manufacturing, it can be pulled out only in that direction.

Therefore, an object of the present invention is to provide an auxiliary table which can be stored on the lower surface of the top plate, which has a simple structure and can be stably operated without rattling. Is. It is also an object to provide an auxiliary table that can be selectively pulled out in either the left or right direction according to the operator or the purpose of the work.

[0008]

In order to achieve the above object, the present invention provides a top plate for a personal computer rack or the like in which a top plate thinner than the top plate is connected inside a horizontal frame so that their upper surfaces are aligned. A pair of guide rails 4, 4 is provided on the lower side of 3a.
Extend in a direction intersecting with the horizontal frame 2b, a table plate 5 is arranged between the guide rails 4 and 4 at substantially the height of the lower surface of the horizontal frame 2b, and is guided in a horizontal groove 5a formed in the side wall of the table plate 5. The rail 4 is fitted in and the table plate 5 is slidably supported along the guide rail 4. In a personal computer rack or the like in which the horizontal frame 2b extends in the depth direction, the guide rails 11 are provided over the entire width of the top plate 3a.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a main body of a personal computer rack, which is a vertical frame 2a made of a rectangular pipe.
And the horizontal frame 2b is assembled, the left and right vertical frames 2
A top plate 3a and a shelf plate 3b are installed in different stages between a, 2a, ..., and a personal computer main body and a peripheral device (not shown) such as a display and a printer can be placed on each. As shown in FIGS. 1 to 4, the top plate 3a is used.
Is connected to the horizontal frames 2b and 2b, and the thickness thereof is set to be thinner than that of the horizontal frame 2b, and the upper surfaces of the both 3a and 2b are mounted so as to be aligned. Reference numerals 4 and 4 denote a pair of guide rails mounted on the lower side of the top plate 3a in the left-right direction, and support the table plate 5 so that the table plate 5 can be freely taken in and out on the right side.

That is, as shown in FIG. 3, the guide rail 4 is formed by projecting a horizontal support portion 4b at one end of the rising portion 4a so as to have a substantially S-shaped cross section. The top plate 3a is attached to the left and right sides of the lower surface of the top plate 3a so as to face each other with screws 6 and the like. On the other hand, as shown in FIG. 2, the table plate 5 has lateral grooves 5a which are slightly wider than the thickness of the horizontal support portion 4b of the guide rail 4 on both sides in the drawing direction.
The horizontal support portion 4b is fitted in the lateral groove 5a to slidably support the table plate 5. At this time, the height X of the rising portion 4a is set such that the portion projecting below the lower surface of the horizontal frame 2b is slightly longer than half the thickness of the table plate 5 to allow a gap between the horizontal table 2b and the table plate 5. The upper surface of the table plate 5 is prevented from coming into contact with the lower surface of the horizontal frame 2b while being packed as much as possible.

In the auxiliary table having the above structure, the horizontal support portion 4b of the guide rail 4 has the lateral grooves 5 on both sides of the table plate 5.
Since it is fitted over the entire length in a, the table plate 5
Does not oscillate and can be used stably without rattling regardless of the amount of pulling out.

Next, FIG. 5 shows another embodiment of the present invention, which is different from the previous embodiment only in the setting of the lengths of the guide rail and the table plate. In the figure, 11 is a guide rail provided under the top plate 3a over substantially the entire width thereof. Further, 12 is a table plate having substantially the same length as the guide rail 11. In this case, as shown in (B), the table plate 12 can be pulled out to an arbitrary length in either the left or right direction. Therefore, for example, in mouse work, a right-handed person can pull out the table plate 12 in the right direction and a left-handed person can pull out the table board 12 in the left direction, and can be used as an auxiliary table for a mouse.
This can be used in a wide variety of ways, such as being used as a space for placing an input document at the time of keyboard input. In this case, the length of the table plate 12 does not necessarily have to be the same as the length of the guide rail 11, and may be a length that can secure a necessary work space when the table plate 12 is pulled out to the left or right.

In each of the above-mentioned embodiments, it is preferable that the surfaces of the table plates 5 and 12 are processed so as to increase the frictional resistance when the main purpose is mouse work, for example. It is also possible to provide a recess of a predetermined area on the upper surface and use it as a tray for small office products. It is also possible to provide a handle on the table plate so that it can be easily pulled out or stored. Further, a stopper may be provided to regulate the amount of pulling out the table plates 5 and 12. For example,
Explaining a later-described embodiment, as shown in FIG. 6, locking pieces 13 are provided at both ends of the guide rail 11 so as to hold the lower edge of the table plate 12, while
The locking projection 1 is provided at the center of the lower edge of the table plate 12 in the longitudinal direction.
Project 4 As a result, when the table plate 12 is pulled out to the left or right, the locking projections 1 are locked by the left and right locking pieces 13.
4 is locked, the withdrawal of the table plate 12 is restricted in either the left or right direction, and the table plate 12 does not fall out accidentally. In this case, the locking piece 13 need not be provided integrally with the guide rail 11, but may be provided at a position that restricts the movement of the table plate 12 in relation to the locking projection.

In each of the above embodiments, the horizontal frame 2
Although the rack in which b extends in the depth direction (front-rear direction) has been described, the present invention can be applied to a rack in which the horizontal frame extends in the width direction (left-right direction). Even in that case, on the premise that the top plates thinner than the horizontal frame are continuously installed so that the upper surfaces of both are aligned, the guide rail and the table plate having the same configuration as in the above embodiment are extended in the direction intersecting the horizontal frame. It will be installed and the table board will be pulled out to the front.

[0015]

As described above, since the auxiliary table according to the present invention has a simple structure, it can be manufactured easily and the cost can be reduced, and there is no rattling regardless of the amount of the table plate pulled out. Therefore, it is possible to perform various stable operations on that aspect. Furthermore, since it can be selectively pulled out in either the left or right direction, it can be used as an auxiliary table for a mouse for both right-handed and left-handed people, and can be used for placing originals and various work. It can also be used as an auxiliary table.
