Embodiments Hereinafter, this invention will be explained based on illustrated embodiments.

In Fig. 1, reference numeral 1 designates a rectangular top plate, and on its lower surface side, leg plate mounting portions 1a are provided in pairs at the front and rear portions at four positions in total, including both left and right ends and two intermediate positions.
1b, 1c, and 1d are formed. 2 is a rectangular curtain plate that forms the back of the desk, and the leg plate attachment part 1 of the top plate 1
Paired leg plate attachment portions 2a, 2b, 2c, and 2d are formed at four positions corresponding to a to 1d at the top and bottom, respectively, and between the left end attachment portion 2a and the left middle attachment portion 2b, and the right middle attachment portion 2a, 2b, 2c, and 2d are formed. Sleeve box unit mounting portions 2e, 2e are provided near the top between the mounting portion 2c and the right end mounting portion 2d, respectively. Reference numeral 3 designates a pair of rectangular leg plates on the left and right, each of which has lock holes 3a opened on one side at two locations on the front and rear of the upper edge and two locations on the upper and lower rear edges, and a pair of sleeve box unit mounting portions on the front and rear. 3b, 3b are formed near the top on the same mold surface side as above. 4 is a pair of left and right two-stage drawer type sleeve box units formed in a long box shape from front to back, one at the center of the back and two at the front and back of one side.
Attachment holes 4a, 4b, 4b are bored at these locations. Reference numeral 5 denotes an adjuster star screwed onto the lower end surface of each leg plate 3 at two locations, front and rear.

As shown in FIG. 2, the leg plate attachment portion 1a of the top plate 1
~1d are screw holes 6 each with an embedded nut.
It is made up of a pair of a and a dowel hole 6b. On the other hand, the upper end surface of each leg plate 3 is provided with a bolt insertion hole 3c at a position opposite to the screw hole 6a, and a dowel hole 3d at a position opposite to the dowel hole 6b.
The lock hole 3a communicates with a bolt insertion hole 3c. Reference numeral 7 is a perforated bolt having a round shaft portion 7b having a radial screw hole 7a, a driver groove 7c at one end, and a threaded portion 7d protruding from the other end. Reference numeral 8 indicates a round shaft-shaped dowel having axial unevenness along the entire circumferential surface, and reference numeral 9 indicates a lock screw.

Therefore, the connection between the top plate 1 and the leg plate 3 is achieved by attaching the perforated bolt 7 to the screw hole 6a of the top plate 1 by screwing the threaded portion 7d, and then inserting the round shaft portion 7b of the perforated bolt 7 into the screw hole. Insert the dowels 8 into the bolt holes 3c of the leg plate 3 in such a direction that the dowels 7a communicate with the lock holes 3a, and insert the dowels 8 into both the dowel holes 6b, 3 of the top plate 1 and the leg plate 3.
This is done by inserting the screw 9 into the screw hole 7a of the perforated bolt 7 through the lock hole 3a as shown in FIG.

Further, each of the leg plate attachment parts 2a to 2d of the curtain plate 2 consists of only screw holes 6a formed by embedded nuts similar to those described above, and the rear end surface of the leg plate 3 has the screw holes 6a.
A bolt insertion hole 3c is formed at a position opposite to the lock hole 3c so as to communicate with the lock hole 3a, as described above. Therefore, the curtain plate 2 and the leg plate 3 are connected using the hole bolts 7 and the lock screws 9 in the same way as the above-mentioned connection between the top plate 1 and the leg plate 3, that is, in the connection structure shown in FIG. 3. Concatenated. In addition, a blind cap 10 is fitted into the screw hole 6a of the leg plate mounting portion where the leg plate 3 is not connected, as shown in FIG. 4, to prevent visual recognition from the outside.

On the other hand, the sleeve box unit mounting portions 2e and 3b of the curtain plate 2 and leg plate 3 are also formed with screw holes using embedded nuts. As shown in FIG. 5, the sleeve box unit 4 is constructed by inserting hexagonal socket bolts 11 into the screw holes of the mounting portions 2e and 3b from the inside through the mounting holes 4a and 4b. 2 and the leg plate 3.

In the above member configuration, the leg plates 3, 3 are the top plate 1.
It can be arbitrarily connected and fixed to the curtain plate 2 at any of four positions, including both left and right ends and two intermediate positions. Therefore, the desk can be assembled in two ways: as shown in Figures 6 to 8, both leg plates 3 and 3 are placed in the middle position, as shown in Figure 9, they are placed at both left and right ends, and as shown in Figure 10, they are placed at the right end position. The form placed at the left middle position,
Contrary to FIG. 10, it can be converted to either the left end position or the right middle position. Also the 8th and 9th
It can also be converted to a form in which one or both of the sleeve box units 4, 4 are removed in the form shown in the figure, or a form in which the sleeve box unit 4 is removed in the form shown in FIG. Therefore, the blind cap 10 may be fitted onto the mounting portion 3b where the sleeve box unit 4 is not mounted.

In the above embodiment, since the legs 3, 3 have different surfaces having the lock hole 3a and the sleeve box unit mounting portion 3b, when converting the form shown in FIG. 8 and the form shown in FIG. The left and right sides are swapped together with the units 4, 4, but in order to avoid this, lock holes 3a and mounting portions 3b are provided on both sides of each leg plate 3, and the blind cap 10 is fitted into these 3a, 3b on the unused side. Good too.

In this invention, the detailed structure of each member of the desk can be modified in various ways other than those shown in the example. For example, connecting means other than the perforated bolts 7 may be used to connect the leg plate 3, top plate 1, and curtain plate 2. You can also
It is also possible to employ a configuration in which the top plate 1 and the curtain plate 2 are interconnected. Further, the mounting positions of the leg plate 3 with respect to the top plate 1 and the curtain plate 2 may be five or more. In addition,
The sleeve box unit 4 may have other structures such as a one-drawer type or three or more drawers, and may be attached to the top plate 1 and the curtain plate or leg plate. However, by attaching the unit 4 to the curtain plate 2 and the leg plate 3 as illustrated, a space can be formed between the unit 4 and the top plate 1, so that the upper surface thereof can be used as a shelf.

Effects of the invention The desk according to this invention can be converted into multiple types of assembled configurations with good appearance, with different mounting positions of both leg plates relative to the top plate and curtain plate, so the above configurations can be selected according to the user's usability and preference. It is possible to change the form for a change of mood, and it is possible to improve office efficiency etc. by doing so.

By providing a pair of left and right sleeve box units in the desk, the balance between the left and right sides of the desk as a whole is improved, and a good external appearance with excellent functionality can be obtained. Further, if the sleeve box unit is attached to the curtain plate and the leg plate, a space is created between the upper surface and the top plate, and the upper surface can be used as a shelf and has a good appearance.
