Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table,
In particular, it relates to a table that can be assembled.

[0002]

2. Description of the Related Art In a conventional table, for example, the upper end screw portions of four legs are screwed into the screw holes at the lower portions of the four corners of the top plate, or four screw holes are attached to the fitting holes at the lower portions of the four corners of the top plate. The upper ends of the legs are fitted and mounted.

[0003]

The above-mentioned conventional example has an advantage that the number of parts is small, but in both the screw type and the fitting type, there is a risk of looseness and rattling, and the legs are attached to the top plate. Since the structure is attached directly or through a metal fitting, there is a problem that the top plate is large and thick, and the weight is increased, and the legs are also comparatively heavy as pillars, which is difficult to handle and the transportation cost is high.

[0004]

In order to solve the above problems, the table of the present invention has a plurality of cylindrical legs 1 as shown in the drawing.
A, 1B ..., and the same number of tubular support members 2A,
2B ... and a foldable top plate 3 placed on these supporting members 2A, 2B.
Between the two upper end portions of A, 1B ...
A, 2B ... Are laterally connected, and the connection is made at two locations on the upper end of the tubular legs 1A, 1B.
Attachment holes 4 and 10 or attachment grooves 5 and 12 are provided at the end portions of A, 2B ..., and using the attachment hole 4 or attachment groove 5 to the edge of the hole 4 or groove 5, respectively. Bolt 6 joined
Alternatively, it is characterized by tightening the nut 7 or the bolt 6 to the nut 7.

A to 1D and the same number of four rectangular tubular supporting members 2 as the number of legs
A to 2D and a foldable quadrangular top plate 3 placed on these cylindrical supporting members 2A to 2D. Each tubular leg 1A
1 and 2 at two locations on the two adjacent surfaces of the upper end of 1D.
As shown in (A), a quadrangular mounting hole 4 is provided, and the quadrangular mounting hole 4 is provided inside the two adjacent surfaces of the tubular legs 1A to 1D.
The through hole 8 is aligned with and the L-shaped interposing material 9 is joined.

Further, as shown in FIGS. 1 and 2 (A), quadrangular mounting holes 10 are provided at two locations on the other two adjacent surfaces of the upper ends of the tubular legs 1A to 1D. The tip end is obliquely cut and brought into contact with the hole 10, and the rectangular tubular support members 2A to 2
D is inserted, and the nut 7 is joined around the mounting holes 4 of the tubular supporting members 2A to 2D. Mounting holes for the tubular legs 1A to 1D 4, through holes 8 of the L-shaped interposer 9, and tubular support members 2A to 2D.
The table is assembled by tightening the bolt 6 with the spring washer 11 onto the nut 7 through the mounting hole 4 of the cylindrical support members 2A to 2D except the upper surfaces of the cylindrical legs 1A to 1D.
The foldable top plate 3 is placed on D, and the top end of each leg prevents horizontal movement of the top plate 3. In this case, it is desirable that the top plate 3 and the upper surfaces of the legs be horizontal.

In order to prevent the head of the bolt 6 from protruding and becoming an obstacle, as shown in FIG. 2 (B), each of the cylindrical legs 1A-1.
This can be solved by recessing the mounting hole 4 portion provided on the two adjacent surfaces of D by the thickness of the bolt head and retracting the bolt head into the recess 15. Further, in order to avoid assembling failure due to dimensional error, the mounting holes may be vertically elongated holes 10 or vertically elongated grooves 12 as shown in FIGS. Can be The foldable top plate 3 is formed by foldably connecting a plurality of wooden boards, synthetic resin boards, and metal boards with a cloth fabric or a synthetic resin sheet. As shown in FIG. 4, the top plate 3 may be mounted by mounting the cylindrical legs 1A to 1D and the cylindrical support members 2A to 2D on the same surface with the upper surfaces thereof being the same surface, or by covering the table body with this. The top plate 3 having the lower peripheral edge portion 3A on the outer periphery is placed on the.

FIG. 5 is a cross-sectional plan view showing the main body of the second form of the table of the present invention, and FIG. 6 is an enlarged cross-sectional view of the connecting portion between the cylindrical leg and the cylindrical supporting member in the second form. This second form is
Four circular cylindrical legs 1A to 1D and four cylindrical support members 2A to 2D having the same number of legs and a circular outer shape and a square cross section.
And a foldable circular top plate (not shown) placed on these cylindrical supporting members 2A to 2D. Each tubular leg 1
The arc-shaped connecting member 1 is provided in the through hole 13 formed at the upper end of A to 1D.
4 is fitted and attached, and both ends of each arcuate connecting member 14 are joined to the bolts 6 with the spring washers 11 and the tubular supporting members 2A to 2D in the both ends of the tubular supporting members 2A to 2D. Tighten with the nut 7. In order to prevent the head of the bolt 6 from protruding and becoming an obstacle, the end portions of the arc-shaped connecting member 14 and the cylindrical supporting members 2A to 2D are recessed as shown in FIG. Washer 11 joined to recess 15
Secure with bolts 6 and nuts 7.

The folding circular top plate 3 is a circular tubular leg 1
Placed on the circular tubular support members 2A to 2D except A to 1D,
Or, the circular cylindrical legs 1A to 1D and the circular cylindrical supporting members 2A to 2
The upper surface of D is placed on the same surface and mounted, or the top plate 3 having a lower peripheral portion on the outer periphery is mounted so as to cover the table body. In addition, 13 is a through hole provided in the cylindrical legs 1A to 1D for inserting the arc-shaped connecting member 14, and 16 is a through hole of the connecting member 14.

According to the first and second embodiments, since the bolt and nut type is used, it is difficult to loosen and there is no risk of rattling. During transportation, a plurality of tubular legs 1A to 1D, the same number of tubular support members 2A to 2D, and the pre-assembled parts of the folding top plate 3 (the bolts 6 or the nuts 7 are tubular legs). Or joined to the support material and screwed together), and then,
Assemble to complete the table. The legs and supporting materials are tubular and robust and lightweight, and the top plate is not attached to the legs directly or via metal fittings, and since it is foldable, it is small and can be made as thin as possible. It is lightweight and easy to handle, and transport costs can be reduced. Further, also in this second embodiment, it is possible to prevent the head portion of the bolt 6 from protruding and becoming an obstacle as shown in FIG. 7 by providing the concave portion 15.

[0011]

As described above, according to the present invention, a plurality of tubular legs, the same number of tubular support members as the number of legs, and the foldable type which is placed on these tubular support members. Consisting of a top plate,
Since each of the tubular supporting members is laterally connected between two locations at the upper end of each of the tubular legs, the number of parts during transportation does not increase so much, and the legs that are the main parts are provided. And the supporting material is tubular and robust and lightweight, the top plate directly attaches the legs to it,
Alternatively, since it is not attached via metal fittings, and it is a foldable type, it is small, can be made as thin as possible and is lightweight, and it is easy to handle and the transportation cost can be reduced.
