[Problems to be solved by the invention]
However, in the above-mentioned Patent Document 1, the corner joints constituting the end portions of the top plate support frame are superposed vertically and the opening angle between the two is determined, and then the upper corner joint is screwed with one screw. The top frame support frame was tightened together. For this reason, if the screw is tightened too tightly during tightening, the set angle position will change, and if it is loose, the set angle position will not be determined. In any case, the mounting screw will be used when attaching the top plate to the top plate support frame. There was a risk that the position would shift.
[0005]
The present invention has been made in view of such circumstances, and provides a top plate support structure such as a table that can accurately and reliably set and support the angle of the two top plate support frames relative to the bracket. It is for the purpose.

As shown in FIG. 5B, the connection beam F1 is formed with a height from the upper surface of the support surface 7b of the bracket B1 to the top plate mounting portion 8, and the height and the lateral width of the connection beam F1 are the same as those of the connection beam F1. It is formed in the same shape as the intermediate beam 6 to be connected, and has a box-shaped structure of a predetermined length having a hollow portion 22 having a partially opened bottom surface and top plate inner surface side.
[0019]
Further, a boss 20 having an insertion hole 26 through which the shaft portion of the bolt 28 is vertically inserted is formed on one end side of the connection beam F1, and a fitting that can be inserted into the fitting boss 12a of the bracket B1 is formed on the lower surface thereof. A joint hole 25b is formed, and a counterbore hole 25a for accommodating the head of the bolt 28 is formed on the upper surface.

In addition, a stepped fitting projection 14 that can be fitted to the inner peripheral wall 6a of the end of the intermediate beam 6 is formed on the end surface of the cylindrical cross section formed on the other end side of the connecting beam F1, and is formed in the center. A bolt insertion hole H is formed in the.
[0021]
As shown in FIG. 5 (a), a plurality of positioning holes Q1, Q2 and Q3 are formed on an arc having a radius centered on the insertion hole 26 of the connection beam F1, and the radius is shown in FIG. 4 (a). It is equal to the distance from the center of the insertion hole h1 of the fitting boss 12a of the bracket B1 shown to the positioning pin P1. The positioning hole Q2 disposed in the middle is configured as two communicating positioning holes Q2′Q2 ″ that are close to each other. Further, a bolt insertion hole 24 for attaching the top plate 2 is formed at substantially the center of the upper surface of the connection beam F1.
[0022]
Accordingly, when the fitting holes 25b of the connecting beams F1 and F2 are inserted into the fitting bosses 12a and 12b of the bracket B1, and the positioning holes Q1 are inserted into the positioning pins P1 and P2 on the bracket B1, respectively.

Thereby, according to the top-plate support structure of this invention, the two crossing connection beams F1 and F2 can be each supported and fixed to arbitrary angle positions by setting a positioning hole. Therefore, even if the shape of the top plate 2 is not only a horizontally long rectangle but also a polygonal shape, the positioning holes Q1 to Q3 of the coupling beams F1 and F2 are selectively inserted into the positioning pins P1. The intermediate beam can be accurately and reliably disposed on the bracket B1 at a predetermined crossing angle along each side constituting the outer periphery of the top plate 2.
[0026]
The bracket B1 and the connecting beams F1 and F2 are rotatably supported by fitting the pair of fitting bosses 12a and 12b and the fitting holes 25b, and are inserted into the insertion holes 26 of the fitting bosses 12a and 12b. Since the bolt 28 is fixed, the rotating part and the fixing part can be performed on the same axis, and the structure is simple and easy to assemble.
[0027]
The angular positions θ1 to θ3 of the connection beams F1 and F2 with respect to the bracket B1 are selected by a plurality of positioning holes Q1, Q2 and Q3 provided on one side and a pair of positioning pins provided on the other side correspondingly. Since this is performed by P1 and P2, the connecting beams F1 and F2 do not deviate in angle with respect to the bracket B1 even when tightening is fixed.
