It is like that. When the first plate member 11 or the second plate member 12 is used as an auxiliary top plate, the upper surface of the top plate 2 and the upper surface of the first plate member 11 or the second plate member 12 that are auxiliary top plates. In this embodiment, the upper surface of the top plate 2 and the upper surface of the first plate-like member 11 or the second plate-like member 12 that are auxiliary top plates are set to be flush with each other. Yes.

  Since the desk 1 of the present invention has the above-described structure, it can exhibit the following effects.

  As shown in FIG. 3, the depth of the work space when the first plate-like member 11 is used as an auxiliary top plate, and as shown in FIG. 6, when the second plate-like member 12 is used as an auxiliary top plate. The depth of the work space is different, and the depth of the work space of the desk 1 can be changed only by changing the mounting method of the rear member 4 according to the size of the room and the growth of the child to be used.

  Moreover, when the 1st plate-shaped member 11 or the 2nd plate-shaped member 12 is used as an auxiliary | assistant top plate, the other 2nd plate-shaped member 12 or the 1st plate-shaped member 11 is as shown to FIG. The basic function does not change to fulfill the function as a back plate, and the rear member 4 always has a back plate. For example, when the back plate is used as a book end, the function can always be exhibited.

  Further, since the first plate-like member 11 or the second plate-like member 12 and the attachment members 5 and 5 are attached and detached by the bolt 8, the depth of the work space of the desk 1 can be easily changed. Along with the change in the depth of the work space, it is not necessary to secure a storage place for the parts and the like in order to use the related members and parts without excess and deficiency, and parts management is easy.

  Since the 1st plate-shaped member 11 and the 2nd plate-shaped member 12 are connected by the L-shape, the rear member 4 becomes a structure which mutually reinforces, and it is hard to produce bending etc. FIG. Furthermore, by providing the side members 13 and 13 between both the plate-like members 11 and 12, the side goods 13 serve as a reinforcing material, and deformation such as bending is less likely to occur.

  In addition, the top plate 2 and the rear member 4 should just be attached to the attachment members 5 and 5, and the number of the attachment holes 9 provided in the attachment members 5 and 5 can be set arbitrarily. Moreover, the attachment method is not limited to said method, Arbitrary attachment methods can be used.

  In the above embodiment, the attachment member 5 is provided at the upper end of the leg member 3, but the attachment member 5 only needs to be provided above the leg member 3, and the top plate 2 is attached to the upper front of the leg member 3. The first plate member 11 or the second plate member 12 may be detachably attached to the upper rear side of the leg member 3, and a part of the leg member 3 may protrude upward from the top plate 2.

  Moreover, in the said Example 1, although the length of the horizontal direction of the top plate 2, the 1st plate-shaped member 11, and the 2nd plate-shaped member 12 was set equally, the length was set so that it may differ. Also good.

  Moreover, in the said Example, although the top plate 2, the 1st plate-shaped member 11, and the 2nd plate-shaped member 12 were formed in square shape, the end surface of the plate-shaped member 11 (12) is formed in the rear end 2a of the top plate 2. If the top plate 2 and the plate-like member 11 (12) can be attached to the attachment member 5 so that 11a (12a) abuts or approaches, the top surface shape of each can be arbitrarily set. For example, the rear end 2a of the top plate 2 is formed in a curved surface such as an arc, and the end surface 11a (12a) of the plate member 11 (12) is formed in a shape corresponding to the rear end 2a of the top plate 2. Even in this case, the maximum length in the direction orthogonal to the horizontal direction of the first plate-like member 11 is set to be different from the maximum length in the direction orthogonal to the horizontal direction of the second plate-like member 12. ing.

  Moreover, in the said Example 1, although the rear member 4 was comprised by one member, you may divide | segment and comprise into two or more members on the right and left.
