The expansion leg 13 is provided on the outer end side of the top plate above the top plate 13 in a state where the top plate is provided.

  The reference support frame 3 and the extended support frame 12 have substantially the same depth width and different frontage widths, and the at least two top plates have a depth width that is different from that of each frame. It is characterized by being constituted by a reference top plate 2 and an extended top plate 11 which are substantially equivalent and have different front and rear widths.

  In the illustrated embodiment, the reference support frame 3, the extended support frame 12, the reference top plate 2, and the extended top plate 11 have substantially the same depth width. Further, the reference support frame 3 and the reference top plate 2 have a rectangular shape whose frontage width is about 2 to 3 times the depth width, and the extended top plate 11 has a frontage width of about 1. The rectangular shape is 5 to 2 times. The extended support frame 12 has a square shape whose frontage width is approximately one time the depth width. The extended support frame 12 and the pair of extended legs 13 are formed in a substantially L shape in front view. Each of the four leg bodies 4 and each of the two extension leg bodies 13 have the same height, and the leg end portion may be provided with an extendable leg end tool or a caster.

At least a part of the frame plate 3A constituting the reference support frame body 3 (or the extended support frame body 12) is formed with a long hole 3a penetrating the upper and lower sides thereof, while the corresponding reference top plate 2 (or expansion) is formed. An embedded nut 17 is provided on the back surface of the top plate 11) so as to match the position where the elongated hole 3a is formed. When the top plate and the reference or expansion support frame are fixed, a bolt fixture 9 is inserted through the elongated hole 3a from below the frame plate 3A, and the bolt fixture 9 is screwed into the embedded nut 17. It is characterized by being fastened and fixed.
The long holes 3a are formed in corresponding portions of at least the front and rear or left and right parallel frame plates 3A constituting the reference support frame 3 (or the extended support frame 12), while the corresponding reference top plate 2 (or the extension) An embedded nut 17 is provided on the back surface of the top plate 11) so as to match the position where the elongated hole 3a is formed.

Thereby, the position of the top plate with respect to the leg can be adjusted, and safety is improved. Further, even when the corresponding positions of the pair of left and right or front and rear paired coupling holes 3a are displaced, the displacement of the position of the pair of bolt fixing members due to the displacement can be adjusted by the long holes.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1A to 1D are explanatory views showing a first embodiment when a desk according to the present invention is extended in the longitudinal direction, and FIG. 2 is an enlarged perspective view of a portion A in FIG.

  In FIG. 1, (a) shows the assembly of the desk concerning this invention, This desk 1 comprises a reference | standard unit, and was arrange | positioned at the lower surface of the reference | standard top plate 2 and the reference | standard top plate 2 so that attachment or detachment was possible. The reference support frame 3 and four legs 4 connected and fixed to the four corners of the reference support frame 3 are provided.

  In this embodiment, the reference top plate 2 has a rectangular shape whose depth dimension is approximately 1/3 of the frontage dimension. The reference support frame 3 that supports the reference top plate 2 on the upper surface is formed in a rectangular shape by connecting four frame plates 3A to the vertical and horizontal dimensions according to the reference top plate 2, and the reference top plate 2 is the reference top plate 2. The support frame 3 is detachably connected to the support frame 3. The four frame plates 3A constitute a curtain plate of the desk 1. Further, as shown in FIG. 1B, the inside of the frame is divided into three equal parts by two beams 5 in order to reinforce the inside of the reference support frame 3.

  As shown in an enlarged view in FIG. 2, the reference support frame 3 and the leg 4 are coupled to each other through the oblique girder material 6, and pass through the left and right sides of the oblique girder material 6, respectively. Thus, the reference support frame body 3 and the diagonal beam member 6 are coupled to each other, and at the center of the diagonal beam member 6 are connected to the leg body 4 by a pair of hexagonal hole screws 8. Note that the reference support frame 3 and the leg 4 can be connected not only by the simple attachment shown in the drawing but also by a woodwork joint structure such as a tenon and a tenon groove or a groove with a groove.

  Further, the reference support frame 3 and the reference top plate 2 are coupled to each other by penetrating the bolt fixture 9 from the bottom surface side of the frame plate 3A through the coupling hole 3a provided in the frame plate 3A in the vertical direction. 9 is brought into contact with the bottom portion of the frame plate 3A, and the shaft end portion of the bolt is screwed to the embedded nut 17 embedded in the corresponding bottom surface of the reference top plate 2 to be detachably coupled.

  A part of the coupling hole 3a penetrating the upper and lower sides of the reference support frame 3 is formed by a long hole, while an embedded nut 2a is embedded in the corresponding back surface of the reference top plate 2, and the reference support frame 3 The bolt fixture 9 is joined by screwing into the embedded nut 17 through the washer 10 through the long hole from the lower surface. Such a long hole is formed at the front and rear of the reference support frame 3 or at positions opposite to the left and right frame plates 3A and 3A.
