A female screw hole (not shown) into which the bolt 28 can be screwed may be screwed into the bottom of the metal fitting embedded hole 21.

  By forming the leg connecting portion 6 in this way, the connecting bolt 26 of the leg portion 5 is screwed into the nut portion 23 of the leg connecting bracket 20, and the upper end surface 29 of the leg portion 5 comes into contact with the peripheral edge of the bracket embedded hole 21. If it is screwed to the top plate 1, the leg portion 5 can be integrally connected to the top plate 1.

  Moreover, in this embodiment, the inclined surface 18 is formed in the both ends of the other side surface 17 of the cover body 4 in which the leg connection part 6 is formed, and the leg connection part 6 is formed in the inclined surface 18. FIG.

  The inclined surface 18 is formed so that the axis of the leg portion 5 is directed outward in the direction of approximately 45 ° with respect to the longitudinal direction of the cover body 4 in a plan view and is inclined approximately 4 ° in a side view. The leg connecting portion 6 is formed along the inclined surface 18 with respect to the inclined surface 18. That is, when the cover body 4 is attached to the back surface of the top plate main body 2 and the leg portion 5 is connected, the leg portion 5 expands outward in a state where an inclination of approximately 4 ° is given to the vertical direction. Is formed.

  Thus, by forming the inclined surface 18 on the cover body 4 and expanding the leg portion 5, the stability as the table B and the reduction of the load on the placed floor surface can be achieved.

  In addition, when it is desired to arrange the legs 5 in the vertical direction, it is not always necessary to form the inclined surface 18 on the cover body 4.

  As shown in FIGS. 2, 4, and 7, the cover body 4 has a plurality of holes through which bolts 11 and 11 for connecting the cover body 4 to the top plate body 2 are inserted. Specifically, two connection reference holes 12 and 12 are formed in the vicinity of the center portion of the cover body 4, and four displacement allowance holes 15 are formed in the periphery of each leg coupling portion 6 and 6.

That is, the cover body 4 is formed so as to penetrate from the one side surface 16 of the cover body 4 to the other side surface 17 in the vicinity of the long side edge portion near the center portion of the cover body 4.

  Further, the cover body 4 is connected to the top plate body 2 by inserting the bolt 11 into the connection reference hole 12 and screwing the bolt 11 into the back surface of the top plate body 2. Further, when warping of the top plate body 2 accompanied by expansion or contraction of the top plate body 2 occurs, the position of the bolt 11 inserted through the connection reference hole 12 is covered with the top plate body 2 and the cover by the displacement allowance hole 15 described later. The positional relationship with the body 4 is configured to be a fixed point Z that does not vary.

  In this embodiment, the bolt 11 for connecting the cover body 4 to the top plate body 2 via the connection reference hole 12 is screwed directly into the back surface of the cover body 4 using wood screws. However, a female screw hole (not shown) into which the bolt 11 can be screwed may be screwed into the back surface of the top plate body 2.

  As shown in FIGS. 2 to 4 and 7, the displacement permissible hole 15 is formed as a long hole 13 in the longitudinal direction of the cover body 4 on the other side surface 17 of the cover body 4 in the vicinity of the leg connecting portions 6 and 6. ing. Specifically, the displacement allowance holes 15 that are formed at four positions on the periphery of one leg connecting portion 6 do not interfere with the horizontal piece insertion groove 10 formed on one side surface 16 of the cover body 4. Two portions are formed on both sides of the horizontal piece insertion groove 10 so as to face each other through the horizontal piece insertion groove 10.

  The displacement allowance hole 15 forms an elliptical counterbore 31 that matches the elongated hole 13 so that the bolt head does not protrude from the other side surface 17 of the cover body 4. Further, the position of the bolt 14 inserted through the displacement allowance hole 15 is attached with the central portion of the displacement allowance hole 15 as a reference position, and the cover body 4 does not follow in the same manner when the top plate body 2 is expanded or contracted. It is configured to flexibly follow warping.

  Therefore, when a warp accompanied by expansion or contraction of the top plate body 2 occurs, the top plate body 2 is inserted into the connection reference hole 12 of the cover body 4 that passes through the central portion of the top plate body 2 as a starting point of expansion and contraction. The position of the bolt 11 is a fixed point Z at which the positional relationship between the cover body 4 and the top plate body 2 does not vary. Instead, the position of the bolt 14 inserted through the displacement allowance hole 15 as the top plate body 2 is displaced. Displace. That is, except for the fixed point Z, the positional relationship between the cover body 4 and the top plate body 2 is changed, and the load on the cover body 4 is greatly reduced.

  In the present embodiment, the plurality of bolts 14 for connecting the cover body 4 to the top plate body 2 via the displacement allowance holes 15 are screwed directly on the back surface of the top plate body 2 using wood screws. However, a female screw hole (not shown) into which the bolt 14 can be screwed may be screwed into the back surface of the top plate body 2.

  As described above, in the top plate structure A including the reinforcing member 3 sandwiched between the top plate body 2 and the cover body 4, even if the top plate body 2 is simply expanded or contracted, the cover body 4 is not subjected to a load. Furthermore, since the reinforcing material 3 is sandwiched between the top plate body 2 and the cover body 4 with play, the top plate body 2 and the cover body 4 are not subjected to an unnecessary load. Moreover, when the top plate body 2 is warped, the reinforcing material 3 can surely prevent the warp.

  The top plate 1 configured as described above forms a table B by connecting the four legs 5.

  As shown in FIG. 6, the leg 5 includes a substantially inverted conical leg main body 35, a connecting bolt 26 projecting from the upper end of the leg main body 35, a height adjusting unit 36 formed at the lower end, It consists of.

Yes.

  Further, the connecting bolt mounting hole 38 is formed in a circular shape on the lower side, and the upper side is formed in a square shape having an opening larger than the circular opening on the lower side to form a two-stage opening. These two openings are at least larger than the outer shape of the nut portion 23 formed in the leg connecting bracket 20 of the cover body 4, and the connecting bolt 26 and the nut portion 23 are screwed into the connecting bolt mounting hole 38. The nut portion 23 is formed so that it can be inserted without load.

  The height adjusting portion 36 disposed at the lower end portion of the leg portion 5 includes a metal adjusting base portion (not shown) disposed at the lower end portion of the leg main body portion 35 and an installation base portion 40 that contacts the floor surface. The adjustment base is threaded with a female screw hole (not shown) in the center, and a male screw (not shown) standing at the center of the installation base 40 is screwed into the installation base. The portion 40 can be moved up and down freely. Therefore, if the length of the leg part 5 is adjusted by the height adjustment part 36, it can be used as a stable table B balanced with the other leg parts 5.

  Moreover, about the top-plate structure A and the table B, the modification as shown to Fig.9 (a), (b) is also employable.

  The top plate structure A ′ according to the modified example employs the structure of the cover body 4 ′ in which the cover body 4 is not provided with the leg connecting portion 6. As shown in FIG. 9A, the cover body 4 ′ is provided with a leg connecting portion 6 in which the cover body 4 ′ is disposed at the center in the longitudinal direction on the back surface side of the top plate body 2. By using together with the cover body 4, it is possible to make a top plate structure A ′ and a table B ′ that can supplementarily prevent the warp on the short side 19 side of the long top plate 1 in particular. Note that it is not necessary to form the inclined surface 18 in such a cover body 4 '.

  Further, as shown in FIG. 9 (b), cover bodies 4 'and 4' according to this modified example are arranged at both end edges of the top plate body 2, and leg parts are formed inside the cover body 4 '. 41 and 41 can be arrange | positioned and the top-plate main body 2 can also be used in the form which mounts on this leg part structure 41 and 41.

The top plate structure A can be provided.

  Further, since the reinforcing material 3 is loosely fitted between the back side of the top plate body 2 and the cover body 4, the reinforcing material 3 is not fixed to the top plate body 2 or the cover body 4, so that the top plate body 2 expands. Even if it shrinks, the reinforcing material 3 does not follow the top plate body 2 and the cover body 4 and does not apply an unnecessary load to the top plate body 2 and the cover body 4. The effect can be demonstrated.

  Further, the reinforcing member 3 has a horizontal piece 7 that is horizontal in the longitudinal direction and a vertical piece 8 that stands upright from the horizontal piece 7, and the vertical piece 8 can be inserted into the back side of the top plate body 2 from the vertical piece 8. A long vertical piece insertion groove 9 is formed, a horizontal piece 7 is freely inserted into one side surface 16 of the cover body 4 and a horizontal piece insertion groove 10 longer than the horizontal piece 7 is formed, and at both end edges of the other side surface 17. Since the leg connecting portion 6 is provided, the reinforcing material 3 does not follow the top plate body 2 or the cover body 4 even if the top plate body 2 expands or contracts, and an unnecessary load is applied to the top plate body 2 or the cover body 4. Furthermore, the top plate body 2 can be prevented from warping in the vertical direction and the horizontal direction as much as possible, and the other side surface 17 of the cover body 4 is effectively used to dispose the leg connecting portion 6. Therefore, the appearance of the back surface of the top plate 1 can be simply configured, and the top plate structure A that is excellent in design can be provided.

  Further, since the reinforcing member 3 is formed in a substantially inverted T shape when viewed in cross section, it is possible to prevent the top plate body 2 from warping in the vertical direction and the horizontal direction as much as possible with a simple shape.

  Further, a connection reference hole 12 through which the bolt 11 is inserted is formed in the vicinity of the center of the cover body 4, and the cover body 4 is connected to the back side of the top plate body 2 via the bolt 11.
