(Reassignment work between the desk and shelf of furniture with a top plate)
Next, the work of rearranging the desk main body 2 and the shelf main body 3 of the furniture with a top plate 1 according to the embodiment of the present invention will be described. The furniture 1 with the top plate is switched to the first desk state (see FIG. 1) or the second desk state (see FIG. 2) by the rearrangement work of the desk body 2 and the shelf body 3 (see FIG. 3). FIG. 12 is a diagram for explaining the joining of the desk main body and the shelf main body during the reassignment work. In the following, referring to FIGS. 1 to 3 and FIG. 12, the furniture 1 with the top plate in the first desk state is rearranged to the second desk state, and then the furniture 1 with the top plate in the second desk state is in the first desk state. As an example, the rearrangement work of the desk main body 2 and the shelf main body 3 of the furniture 1 with a top plate will be described.

  First, when the furniture with a top board 1 in the first desk state is rearranged to the second desk state, the user releases the fixed state of the desk body 2 and the shelf body 3 in the furniture 1 with the top board in the first desk state. Then, the shelf body 3 released from the fixed state is lifted, and the shelf body 3 is removed from the shelf support portions 20a and 20b of the desk body 2 as shown in FIG. At this time, as shown in FIG. 12, the user removes the right side plate 33a of the shelf body 3 from the shelf support portion 20a of the right leg 22a by loosening the joining screw 16 or the like. Although not particularly illustrated, the user performs the same operation on the shelf support portion 20b of the desk body 2 and the left side plate 33b of the shelf body 3 as well.

  Subsequently, the user replaces the joint fitting 15 attached to the insertion hole 37a of the right side plate 33a into the insertion hole 39a in the extending portion 32a of the upper shelf board 32 as shown in FIG. Similarly, the user replaces the joining fitting 15 (not shown) inserted in the insertion hole 37b of the left side plate 33b into the insertion hole 39b of the extending portion 32a.

  Next, the user brings the lower surface of the upper shelf plate 32 close to the shelf support portions 20a and 20b of the desk body 2, and the lower surfaces of the end portions in the width direction F2 of the extending portion 32a are respectively shelf support portions 20a and 20b. Place and mount on. At this time, the user inserts each protrusion 28a of the shelf support portion 20a in the right leg 22a into each fitting hole 38a of the extending portion 32a and joins the protruding portion 28a protruding from the insertion hole 39a of the extending portion 32a. The portion of the metal fitting 15 is inserted into the insertion hole 29a of the shelf support portion 20a. At the same time, the user fits each protrusion 28b of the shelf support portion 20b of the left leg 22b into each fitting hole 38b of the extending portion 32a and protrudes from the insertion hole 39b of the extending portion 32a. The portion of the joint fitting 15 is inserted into the insertion hole 29b of the shelf support portion 20b. Thereafter, the user fastens each joint fitting 15 inserted into the insertion holes 29a and 29b by fastening the joint screw 16 or the like. As a result, the upper shelf board 32 is attached and fixed to the desk main body 2 so that the lower surface of the extending part 32a is supported by the shelf support parts 20a and 20b and the drawer support 24. In this way, the user rearranges the furniture 1 with the top board from the first desk state shown in FIG. 1 to the second desk state shown in FIG.

  On the other hand, when the furniture with a top board 1 in the second desk state is rearranged to the first desk state, the user performs a reverse work opposite to the above-described rearrangement work from the first desk state to the second desk state. . Accordingly, the user places and attaches the respective lower end surfaces of the right side plate 33a and the left side plate 33b in the standing direction F3 to the shelf support portions 20a and 20b of the desk main body 2 shown in FIG. At this time, the user fits the projections 28a of the shelf support portion 20a of the right leg 22a into the fitting holes 36a of the right side plate 33a, and protrudes from the insertion holes 37a of the right side plate 33a. Is inserted into the insertion hole 29a of the shelf support portion 20a (see FIG. 12). At the same time, the user fits each protrusion 28b of the shelf support portion 20b of the left leg 22b into each fitting hole 36b of the left side plate 33b and also protrudes from the insertion hole 37b of the left side plate 33b. The portion 15 is inserted into the insertion hole 29b of the shelf support portion 20b. Thereafter, the user fastens each joint fitting 15 inserted into the insertion holes 29a and 29b by fastening the joint screw 16 or the like. As a result, the right side plate 33 a and the left side plate 33 b are attached and fixed to the desk main body 2 so that the lower surface of the lower shelf plate 31 is supported by the drawer support 24. In this way, the user rearranges the furniture 1 with the top board from the second desk state shown in FIG. 2 to the first desk state shown in FIG.

  As described above, in the embodiment of the present invention, articles can be accommodated in the desk main body standing on the floor surface while supporting the top board by the legs, and the first shelf board and the second shelf board. In the furniture with a top plate which is a combination of the shelf main body and the depth dimension of the first shelf board and the second shelf board, the first shelf board and the second shelf board are mutually legged. Are connected by a connecting portion so as to be spaced apart from each other in the standing direction. Furthermore, a shelf support portion is provided on the depth direction back side of the top plate of the leg upper end surface of the desk body, and the first table state in which the top plate and the first shelf plate are arranged in the depth direction, the top plate and the first plate. The shelf main body is received and supported in the standing direction of the legs by the shelf support portion so that the second desk state in which the two shelf boards are arranged in the depth direction is alternatively selected.

  For this reason, by changing the shelf main body with respect to the shelf support portion, the furniture with the top plate can be easily changed to the first desk state or the second desk state, and the furniture with the top plate is in either the first desk state or the second desk state. Even so, it is possible to receive the load from the shelf body by the upper end surface of the leg body, with the floor surface on which the leg body stands (standing) as a support. Thereby, according to the 1st desk state or the 2nd desk state, while the desk surface of the furniture with a top plate can be easily expanded or returned (reduced with respect to the desk surface after expansion), the weight of the shelf body and the shelf board The mounting strength between the desk main body and the shelf main body can be sufficiently strengthened against the weight of the article placed thereon or an external impact applied to the shelf main body. As a result, it is possible to secure a strong mounting strength of the shelf main body with respect to the desk main body (specifically, the leg), and it is possible to easily adjust the area of the desk top surface of the furniture with the top plate.

  In addition to this, even if the furniture with the top plate is rearranged into the first desk state or the second desk state, the first shelf board and the second shelf board are placed in the standing direction of the legs. It can be maintained in a state of being opposed to each other and facing each other. Thereby, the function as at least one shelf board of a 1st shelf board and a 2nd shelf board is always securable irrespective of a 1st desk state or a 2nd desk state. As a result, the shelf board which is not arranged in the depth direction of the top board among the first shelf board and the second shelf board can be effectively used as an article storage shelf or the like without being wasted.

  Moreover, in embodiment of this invention, the 1st shelf board or the 2nd shelf board is detachably fixed in the state supported by the shelf support part. Thereby, the attachment intensity | strength of the shelf main body with respect to a desk main body can be strengthened more.

  Furthermore, in the embodiment of the present invention, as the connecting portion for connecting the first shelf board and the second shelf board, the width direction end portion of the first shelf board and the width direction end portion of the second shelf board are used. In a state where the first shelf plate or the second shelf plate is supported by the shelf support portion, the side plate is detachably fixed to the leg body. Thereby, it is not necessary to form a fixing structure such as a protrusion and a fitting hole necessary for fixing the first shelf plate or the second shelf plate and the leg as much as possible. As a result, there is a step (unevenness) due to the fixed structure on the surface (for example, the upper surface or the lower surface) of the first shelf plate or the second shelf plate, and the first shelf plate or the second shelf plate can be used freely or The situation that damages the aesthetics can be avoided as much as possible. In addition, since the shelf body can be formed into a rectangular frame-like structure in front view, the strength of the shelf body itself can be increased.

  Moreover, in embodiment of this invention, let a 1st shelf board be a lower shelf board which has the same depth dimension as a shelf support part, and a 2nd shelf board is on the upper side of a standing direction rather than a 1st shelf board. It is set as the upper shelf board which has a depth dimension longer than a 1st shelf board, and the upper shelf board is extended to the near side of the depth direction rather than the lower shelf board by the depth dimension of a shelf support part. For this reason, in the 1st desk state, the front end part of the depth direction of a lower shelf board can be made to contact the depth end part of the depth direction of a top plate. As a result, the top plate and the lower shelf plate can be made continuous in the depth direction, and as a result, the top surface of the top plate and the upper surface of the lower shelf plate can be made in a continuous and flush state. The top plate and the lower shelf board can be easily used as the desk top surface or the shelf board while ensuring the beauty of the desk top face. Further, in the second desk state, the front end of the upper shelf board in the depth direction can be brought into contact with the depth end of the top board in the depth direction. Thereby, a top plate and an upper shelf board can be made to continue in the depth direction. As a result, since the top surface of the top plate and the top surface of the top shelf can be made continuous, the desk top surface can be expanded while ensuring the beauty of the top surface of the furniture with the top plate, and the top plate and top shelf Can be easily used as a desk top surface or a shelf board.

  Furthermore, in the embodiment of the present invention, the depth end in the depth direction of the first shelf plate and the depth end portion in the depth direction of the second shelf plate are connected by a back plate, and the upper end portion of the back plate is The back plate is configured so as to protrude above the upper surface of the shelf plate located on the upper side in the standing direction among the first shelf plate and the second shelf plate. As a result, it is possible to prevent the article placed on the upper shelf (specifically, the upper shelf) from falling out of the first shelf and the second shelf by the upper end of the back plate. it can.

  In the above-described embodiment, the depth dimension of the upper shelf board 32 is longer than that of the lower shelf board 31, but the present invention is not limited to this. In the present invention, the depth dimension of the upper shelf board 32 may be shorter than the depth dimension of the lower shelf board 31. At this time, the depth dimension of the upper shelf board 32 is set to the same dimension as the shelf support parts 20a and 20b, and the lower shelf board 31 extends to the near side in the depth direction from the upper shelf board 32 by the depth dimension of the shelf support parts 20a and 20b. May be present.

  Further, in the above-described embodiment, in the furniture 1 with the top board in the second desk state, the upper shelf board 32 is supported by the shelf support portions 20a and 20b, and the lower shelf board 31 is in the standing direction F3 rather than the top board 21. However, the present invention is not limited to this. When the furniture 1 with the top plate is set to the second desk state, the upper shelf 32 is supported by the shelf support portions 20a and 20b by turning the shelf body 3 upside down, and the lower shelf 31 is more than the top plate 21.
