Therefore, in this embodiment, a total of four columns 1 of one type, front, rear, left and right, are simultaneously molded together with the frame forming body 2 by utilizing the central opening space of the frame forming body 2, and these columns are assembled and constructed. 1 is removed and sequentially inserted into and locked into the frame forming body 2 to be constructed.

The wooden top plate insertion connection member 9 is integrally molded with an appropriate synthetic resin member as shown in FIGS. 1 to 4, and includes an attachment portion 9a attached to the upper insertion end portion 7B of the support column 1. A wooden top plate insertion engagement recess 10 provided with a circular flat cross section is provided with an insertion engagement convex portion 9b having a circular flat cross section that can be inserted and engaged.

Specifically, the wooden top plate insertion connection member 9 is provided with a plurality (two) of insertion engagement convex portions 9b, and each of the insertion engagement convex portions 9b can be inserted and engaged with the wooden top plate insertion engagement. A plurality (two each) of recesses 10 are provided at the four corners of the wooden top plate 3. The number of the insertion engaging protrusions 9b and the insertion engagement recesses 10 of the wooden top plate can be changed as appropriate.

Further, in the present embodiment, the insertion engagement convex portion 9b is a hollow columnar body having a circular flat cross section, and a plurality of protrusions 9c are provided at equidistant positions in the circumferential direction on the side peripheral surface of the insertion engagement convex portion 9b. (Four) are provided.

Further, in this embodiment, when the insertion convex portion 9b is inserted into the wooden top plate insertion engagement recess 10 and engaged, the concave portion 11 having a circular flat cross section provided at a predetermined position on the lower surface of the wooden top plate 3 is uneven. A convex portion 12 having a circular flat cross section to be fitted is provided on the wooden top plate insertion connecting member 9.

The concave portion 11 is formed by cutting on the wooden top plate 3 with an end mill, and the convex portion 12 is integrally formed with the wooden top plate insertion connecting member 9.

Further, the positions of the concave portion 11 and the convex portion 12 are set so that the support column 1 is placed at the correct position on the front, back, left and right of the wooden top plate 3 (the inner opening of the support column 1 having a U-shaped flat cross section faces inward). The top plate insertion engagement recess 10 is provided so that the convex engagement portion 9b can be inserted and engaged only when it is engaged, so that it can be inserted and assembled when the connection position of the support column 3 is correct. Has been done.

It should be noted that the concavo-convex fitting of the concave portion 11 and the convex portion 12 makes the rotation stopper of the support column 1 more rigid, and in consideration of this point, the number of the concave portion 11 and the convex portion 12 may be plural.

Further, in this embodiment, as shown in FIG. 5, a leg body 13 that is inserted and connected to the lower insertion engaging portion 8A of the lowermost frame forming body 2 is provided, and the leg body 13 is provided with a universal caster. And wheels (rollers) are detachably connected.

As shown in FIG. 1, the drawer body 5 is integrally molded with an appropriate synthetic resin member, and is each composed of a square plate-shaped front portion, bottom portion, left and right side surface portions, and back surface portion, and has an upper opening. It is a case body having a part.

In this embodiment, four drawer bodies 5 are provided, and each drawer body storage portion of the frame-shaped main body portion is provided so as to be able to be pulled out freely.

Since this embodiment is configured as described above, the upper insertion end portion 7B on the upper side of the support column 1 provided on the upper surface side of the frame forming body 2 is inserted into the wooden top plate insertion engaging recess 10 of the wooden top plate 3. The frame-shaped main body 4 is assembled and constructed by connecting via the connecting member 9. A drawer 5 is freely pulled out between the frame forming body 2 and the wooden top plate 3.

By the way, in this embodiment, as described above, the upper insertion end portion 7B on the upper side of the support column 1 is connected to the wooden top plate insertion engaging recess 10 of the wooden top plate 3 via the wooden top plate insertion connection member 9. The wooden top plate insertion / connection member 9 is inserted into and engaged with the mounting portion 9a attached to the upper insertion end 7B of the support column 1 and the wooden top plate insertion / engagement recess 10 provided in a circular shape. A possible insertion-engagement convex portion 9b is provided.

That is, in this embodiment, the wooden top plate insertion engaging recess 10 provided in the wooden top plate 3 can have a circular flat cross section by connecting via the wooden top plate insertion connection member 9. If it is a concave portion with a circular flat cross section, it is extremely easy to manufacture, so the cost is low, and since a highly accurate connection structure can be obtained, rattling of the wooden top plate 3 and the support column 1 can be prevented as much as possible. It will be.

Further, in this embodiment, the wooden top plate insertion / connection member 9 is provided with a plurality of insertion / engagement protrusions 9b, and the wooden top plate insertion / engagement recesses 10 to which each of the insertion / engagement protrusions 9b can be inserted / engaged. Is provided on the wooden top plate 3, so that the connection strength between the wooden top plate 3 and the support column 1 can be obtained, and of course, even if the wooden top plate insertion engagement recess 10 is circular, the axis rotation of the support column 1 can be obtained. It is definitely prevented.

Further, in this embodiment, since the insertion engagement convex portion 9b has a circular flat cross section, the insertion into the wooden top plate insertion engagement recess 10 is satisfactorily performed.

Further, in this embodiment, since the protrusion 9c is provided on the side peripheral surface of the insertion engagement convex portion 9b, it is possible to further prevent rattling from occurring.

Further, in this embodiment, the upper insertion end portion 7B on the upper side of the support column 1 has a U-shape or a square shape in a plan view, and the attachment portion 9a is configured so as to be attached to the upper insertion end portion 7B in a fitted state. Therefore, the support column 1 that connects the frame forming bodies 2 to each other can be used as it is as the connecting structure of the wooden top plate 3.

Further, in this embodiment, when the insertion convex portion 9b is inserted into the wooden top plate insertion engagement recess 10 and engaged, the convex portion that is unevenly fitted to the concave portion 11 provided at a predetermined position on the lower surface of the wooden top plate 3. 12 is provided in the wooden top plate insertion connecting member 9, and the positions of the concave portion 11 and the convex portion 12 are set so that the support column 1 is inserted into the wooden top plate insertion engagement concave portion 10 at the correct position of the wooden top plate 3 and the engagement convex. Since the portion 9b is provided so that it can be fitted unevenly only when it is inserted and engaged, and it can be inserted and assembled when the connection position of the support column 3 is correct, it is possible to surely perform an incorrect assembly construction. Can be prevented.

Further, in this embodiment, since the wooden top plate insertion / connection member 9 is integrally molded with a synthetic resin member, the shape and size of the wooden top plate insertion / connection recess 10 are accurately adjusted to match the wooden top plate insertion / engagement recess 10. Can be manufactured.

The present invention is not limited to the present embodiment, and the specific configuration of each constituent requirement can be appropriately designed.
