  When the table is manufactured by assembling these components after manufacturing the respective components in this way, it can be roughly divided into a mounting process of the reinforcing frame 2 or the bracket 23 to the top plate 1 and a mounting process of the module leg 49. These are assembled separately at a factory, for example, and the assembly assembly is packed together or individually and transported to customers such as dealers. When the assemblies are prepared, they are assembled to produce a table. .

Among these, the attaching process of the reinforcing frame 2 or the bracket 23 to the top plate 1 is performed by screwing the reinforcing frames 2 and 2 at predetermined positions on the lower surface of the top plate 1 and reinforcing them between the metal fittings 2 and 2. The frames 43 and 44 are attached to the top plate 1.
Then, both ends of the connecting shaft 3 are spanned between the through holes 14 of the reinforcing frames 2, 2, and the pipe shaft 6 on which the torsion spring 10 is mounted with the lock link 5 outside the shaft end. insert.

Next, one end of the lock lever 11 is inserted into the through hole 15 from the outside of the reinforcing frame 2, and the end of the lock lever 11 is inserted into the connecting shaft 3 through the pipe shaft 6. The screw hole 12 is aligned.
Then, the screw 7 is inserted into the through-hole 8 and the through-hole 4 and screwed into the screw hole 12 to connect the connecting shaft 3, the lock link 5, and the lock lever 11 movably, and further to the torsion spring 10. One end of the connecting shaft 3 is hooked on the lock link 5 and the other end is engaged with the reinforcing frame 2 to urge the connecting shaft 3, the lock link 5, and the lock lever 11 to return to the original positions so as to be rotatable.

On the other hand, leg joints 48 are welded to both ends of the pair of support frames 47, brackets 23 are welded to both ends of one of the support frames 47, and the brackets 23 are connected to the reinforcement frames 2 and 2. The adjustment fitting 19 is arranged between the first and second cams 26, 27.
Then, the insertion holes 17 of the bent pieces 2a, 2a, the shaft holes 38, 38 of the first and second cams 26, 27, and the shaft hole 20 of the adjustment fitting 19 are aligned, and the reinforcing frame 2 is placed in these positions. , 2 is inserted from the outside, and the reinforcing frames 2 and 2, the adjustment fitting 19 and the bracket 23 are rotatably connected.

Thereafter, the pin 40 of the connection piece 39 is press-fitted into the through-hole 37 of the first and second cams 26, 27, and both ends of the pivot 18 are engaged with the stepped portion to prevent the pin 40 from coming off.
The other support frame 47 to which the bracket 23 is not attached is stored in this state and is prepared for the assembly of the table.

Next, in the assembly step of the module leg 49, the fitting portions 61 and 61 of the second leg column 55 are inserted below the leg columns 57 and 57 of the first leg column 50.
At that time, the curved shapes of the curved portions 63, 63 are arranged in opposite phases or substantially back to back, and the lower end portions thereof are separated outward, in other words, the pair of second pedestals 55 are as shown in FIG. When the second leg column 55 is assembled so as to be line symmetric when viewed from the front-rear direction of the table, a screw (not shown) is inserted into the screw hole 59, and this is screwed into the screw hole 62. The pedestal 50 and the second pedestal 55 are connected.

Thereafter, the square hole portion 65 of the leg rod 56 is fitted to the square shaft portion 64 of the second leg column 55, the screw 76 is inserted into the screw hole 75 from below the square hole portion 65, and the screw shaft is screwed into the screw shaft. A leg rod 56 is connected to the second leg 55 by screwing into the hole 74.
At this time, the square shaft portion 64 and the square hole portion 65 have a regular hexagonal cross section, and the major axis of the elliptical cross section of the pedestal 57 or the fitting portion 61 is located in parallel with the longitudinal direction of the table. Therefore, by changing the fitting position of the square shaft portion 64 and the square hole portion 65, the crossing angle θ on the plane of the leg rod 56 with respect to the square shaft portion 64 can be set accurately and easily.

That is, since the square shaft portion 64 and the square hole portion 65 have regular hexagonal cross sections, the crossing angle θ can be variably set every 60 ° by changing the fitting position thereof.
In the embodiment, the crossing angles θ _{1 to} θ ₄ of the front and rear, left and right leg rods 56 are set to 60 ° at equal angles, and the other end portion of the leg rods 56 landing on the floor surface 77, in the embodiment, casters 69. The position on the plane is arranged as close as possible to the four corners of the top plate 1 to ensure stability when the table is used.
Thereafter, the caster 69 is attached by screwing the mounting bolt 70 of the caster 69 into the screw hole 68 at the other end of the leg rod 56, and the cap 78 is fitted into the upper end of the leg column 57.

As described above, the present invention divides the process of attaching the reinforcing frame 2 and the bracket 23 to the top board 1 and the process of assembling the module legs 49, and separately assembles them. The effort is reduced, and these can be assembled rationally and efficiently.
In addition, since the assembly assembly (top plate and leg assembly) for each process can be produced independently, it is possible to meet the prospective production, and by assembling the assembly as described later, it is possible to reduce the time and effort of assembly between them. It is possible to respond reasonably and swiftly to an order for a table.

Next, when assembling a table using the assembly assembly, a set of a top plate and a leg assembly is prepared and assembled.
That is, the convex portion 71 of the leg joint 48 attached to the end of the support frame 47 on the top plate assembly side is connected to the through hole 73 on the inner peripheral surface of the front leg column 57 of the first leg column 50 of the leg assembly. After positioning these, the bolt 52 is inserted into the through hole 59 from the outside of the leg column 57, penetrates the through hole 54 of the leg joint 48, and the nut 53 is screwed into the screw shaft end and tightened. The leg joint 48 is attached to the pedestal 57.

Thereafter, the other support frame 47 without the bracket 23 is prepared, and the leg joints 48 at both ends thereof are positioned on the inner surface of the other leg pillar 57 in the same manner as described above, and these are bolts 52 and nuts 53. Connect through.
When the pair of left and right first leg posts 50 are attached to the ends of the pair of front and rear support frames 47 through the leg joints 48 in this way, the assembly of the table is completed. In addition, since no special tools or skills are required for the assembly work, this can be done easily and quickly.

The assembled table is as shown in FIGS. 1 to 3, and the curved surface of the first pedestal 50 by the elliptical tube, the three-dimensional curved shape of the second pedestal 55, and the pair of front and rear legs 56 facing upward. Due to the curved shape, it has an overall soft and gentle appearance.
Further, as shown in FIG. 1, the pair of front and rear leg rods 56 are curved upward and appear to be superimposed in the inner and outer directions of the table, so that the curved pattern is emphasized and a soft aesthetic feeling is obtained. Provoke.

In addition, the pair of front and rear leg rods 56 are arranged obliquely on the flat surface or bottom surface as shown in FIG. 2 and are substantially square-shaped, and the tip of the caster 69 side is the top plate 1. The front and rear casters 69 are located inside and outside in the left-right direction.
Therefore, compared with the case where all or any one of the pair of front and rear leg rods 56 is arranged in parallel with the front-rear direction of the table, the base end portion of the leg rod 56, that is, the first pedestal 57 side is the inner side of the table. Accordingly, the distance between the left and right leg pads 56 is reduced accordingly, and the bending moment in the left-right direction of the top board 1 is reduced.
Furthermore, since the first and second leg columns 50 and 55 are arranged with a pair of leg columns 57 or curved columns spaced apart from each other, the bending mode in the front-rear direction of the top plate 1 is larger than that of a single unit. -The support strength of the table is improved in combination with the above.

Next, the table is used in the same manner as the conventional folding table. When the table is used, the lock pin 9 engages with the cam groove 29 of the first cam 26 and the upper end of the bracket 23 is engaged. Is positioned so as to be engageable with the inner surface of the reinforcing frame 2, supports the metal fitting 2, and maintains the horizontal state of the top plate 1.

  At that time, the rear caster 69 is offset to the outside of the front caster 69 by the width of the caster 69, and the rear leg 56 is offset to the outside of the front leg 56. Therefore, the casters 69 and the leg rods 56 of the previous and subsequent tables are stacked without interfering with each other.

On the other hand, the adjusting bracket 19 is pivotally supported between the first and second cams 26 and 27 by the pivot 18 penetrating the shaft hole 20 so as to be pivotable in the vertical direction. The engaging piece 22 at the lower end is engaged with the back surface of the bracket 23, and the screw shaft end of the adjusting screw 25 is located in the back surface.
Therefore, when the top plate 1 is normally supported by the reinforcing frames 2 and 2, the adjustment fitting 19 does not function.

  On the other hand, when the inner surface of the reinforcing frame 2 or the upper end portion of the bracket 23 is worn by the abrasion due to the use over time, and the tightness between them is lowered, the tape is caused by the minute gap. When the bull is used, the reinforcing frame 2 or the top plate 1 is tilted forward and the level of the top plate 1 is lowered.

In such a case, a tool such as a screwdriver is inserted into the stepped hole 35 of the connection piece 33 exposed on the back surface of the bracket 23 on the front side of the table, and the adjusting screw 25 is screwed in as appropriate.
In this way, the screw shaft end of the adjustment screw 25 engages with the engagement piece 22 of the adjustment metal fitting 19, and the metal fitting 19 rotates upward about the pivot 18 into which the shaft hole 20 is inserted. The engaging piece 21 is brought close to and engaged with the inner surface of the reinforcing frame 2 to push up the top plate 1 through the metal fitting 2.
For this reason, the front-down state of the top plate 1 is corrected, and the level of the top plate 1 is restored.
In this case, even if the adjustment fitting 19 functions as described above, the folding operation of the top plate 1 and the engagement / disengagement operation of the lock pin 9 with respect to the cam grooves 28 and 29 are not hindered.
