DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk having shelves, such as a learning desk for children.

[0002]

2. Description of the Related Art The shelves attached to children's learning desks are:
Generally, a shelf board is mounted in two steps between the left and right boards, and the back face is further covered with a back board. In addition, 46
JP-A-28817 and JP-B-48-22808 disclose that a pair of right and left columns are fixed to the back of a desk, and a shelf is mounted between the upper ends of these left and right columns.

On the other hand, Japanese Utility Model Publication No. 52-12568 discloses that a pair of left and right supports are attached to the rear side surface of a desk so as to be rotatable in a state of extending upward and a state of extending downward, respectively. Attaching a shelf with an upwardly-facing storage section and a downwardly-facing storage section formed vertically symmetrically,
It is described that an article can be stored in the shelf in each of a state in which the column is rotated to position the shelf above the top plate and a state in which the shelf is positioned below the top plate.

[0004]

By the way, in general, children tend to prefer a high shelf having a plurality of shelves in a lower grade, whereas in a higher grade, only one shelf is required in a higher grade. Tend to prefer low height shelves.

[0005] However, in the case of a form in which a shelf board is mounted between the left and right side boards, the height of the shelf cannot be changed.
If the child's preference changes, the entire shelf is removed and discarded, even if only a single shelf is desired. Space for storing textbooks, etc. that had been stored in the room must be found elsewhere in the room,
There was a problem that the space could not be used effectively.

On the other hand, in the structure described in Japanese Utility Model Publication No. 46-28817 or Japanese Utility Model Publication No. 48-22808, in which a shelf is supported via left and right supports fixed to the back of a desk, the height of the supports is reduced. By changing the height, there is an advantage that the height of the shelf can be changed according to the preference of the user (child).

However, such a structure in which shelves are mounted via left and right supports has a problem that writing implements and notebooks used on a desk cannot be prevented from falling from between the left and right supports. Further, the configuration of the above publications has a problem in that the amount of storage is small because only one shelf is provided between the left and right columns.

Further, in the configuration disclosed in Japanese Utility Model Publication No. 52-12568, the shelves must be formed vertically symmetrically, so that not only the storage volume is small and the space cannot be effectively used, but also the mounting strength of the columns is reduced. There was a problem of being weak.

SUMMARY OF THE INVENTION An object of the present invention is to provide a desk with a shelf device which solves the problems of the prior art.

[0010]

[MEANS FOR SOLVING THE PROBLEMS] To achieve this object
Shelving system with a desk according to the invention of claim 1, "a top board one of left and right
Check that opens the desk is supported by legs of the pairs comprises a rear plate superimposed on the back of the desk so as to upwardly protrude significantly from the top plate, rearward on the lower side of the top plate
While forming between, on the front surface of the back plate, respectively

Was.

[0012]

According to this structure, by changing the height of the back plate to be attached to the desk, the two-stage shelf can be positioned above the top plate, or the one-stage shelf can be placed on the top plate. The height of the plurality of shelves protruding from the top plate can be changed according to the user's preference.

[0013] Even when the shelf is set at a low level, each shelf is attached to the back plate, and a part of the shelf is not removed from the back plate. The textbooks that are frequently used are stored on a shelf, and the frequently used text documents are stored on a shelf located above the top plate, so that the space can be used effectively by separately using a shelf device . In other words, the dead space at the back of the desk can be effectively used as a space for storing objects in a state where the back plate is set at a low level.

Accordingly, the present invention provides a shelf according to the user's preference.
In addition to being able to change the height of the device , there is an effect that the space can be effectively used. In addition, even if the back plate is set to any height, the back of the top plate is covered with the back plate, so that objects used on the desk can be prevented from falling behind the desk, and since a state such that the desk mutually reinforce each other, has an effect capable of improving the overall strength.
