Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an assembly structure of a table in which a top plate is attached to legs.

[Prior art]

For large tables, a horizontal rod is used to connect each leg rod at the base end of the leg rod, so that it can stand on its own, and the table can be constructed by simply attaching the top plate to the top of the horizontal rod. There is something to do. However, it is not possible to accommodate various sizes of the top plate, and a technique has been developed in which the top plate, leg rods, and horizontal rods are constructed separately and then integrated using a bracket during assembly.

Specifically, as an example, Japanese Utility Model Publication No. 48-30097 discloses that, as shown in FIG. 4, the connecting rod part attached to the bracket 04 is inserted into the end of the top plate support rod 01 to form a square top plate support rod. A technique is disclosed in which the top plate 03 is assembled by making a frame, placing the top plate 03 on a stand formed by fixing the legs 02 below the bracket 04, and fixing the top plate 03 with the mounting pieces 06 using screws or the like. .

However, as the table itself becomes larger, the weight of the top plate increases, making it difficult for workers to manually align the top plate, and causing problems such as screw holes not matching up when reassembled. Ta.

Furthermore, it is impossible to automate the assembly work.

[Problem that the invention attempts to solve]

This invention not only allows workers to easily place the top plate when assembling the table, but also allows the screw holes to be automatically aligned, creating a table with a thin top plate and a solid feel. The purpose is to obtain.

[Means to solve the problem]

A supporting base member 3 whose lower part is fixed to the leg tube 1 and holds the top plate support rod 2 horizontally is connected to connecting members 4', 4'', 4 whose outer sides protrude at right angles and whose outer sides stand up diagonally upward. Molded integrally, the connecting member 4',
The upper surface of the top plate support rod 2, which has recesses 5', 5'', 5 at the ends into which 4'', 4 can be fitted, is separated from the inside by a first horizontal surface 6', a rising inclined surface 6'', and a second horizontal surface 6.
Then, the table is constructed by placing the top plate 7 having the shape of the lower surface that matches the shape of the top plate support rod upper surface formed by assembling the top plate support rod 2 and the supporting base member 3. Configure.

[Effect]

A horizontal frame for supporting the top plate is assembled by fitting the connecting members 4′, 4″, 4 and the recesses 5′, 5″, 5, and the four top plate support rods 2 that make up the frame are assembled. , 2 have the shape of 〓, and by defining an installation space for the top plate 7 toward the inside, a top plate having a bottom surface shape that matches the installation space is placed within the frame. By doing this, the left, right, front, and rear positions are automatically determined, and screws can be easily secured.

[Effect of idea]

By employing the above configuration, the following effects are achieved.

(1) There is no need to particularly fix the table when assembling the table, and it also becomes possible to assemble it on an automated line.

(2) Even if a partially assembled table is dismantled for repair or disassembly, once the top plate support rod and support base members are assembled, the top plate position will be automatically determined, and the previously used screw holes will be automatically fixed. Aligned.

(3) Conventionally, there was no overlap between the top plate support rod and the top plate, resulting in increased thickness, but the present invention has a large overlap area, creating a solid and solid feel.

〔Example〕

An example of the present invention will be described based on the drawings.
The support base member 3 has a pipe insertion hole 16 on the lower side for attaching the leg tube 1, receives the guide pipe 13 extending into the leg tube 1, and secures its upper end with a fixing nut 18 installed in the upper nut hole 17. It has a structure in which it is screwed into and fixed with the male threaded portion 14 of. Further, a rotating rod 15 is inserted into the guide pipe 13,
By rotating the tip of the rotary rod 15 protruding above the fixing nut 18, the height of the table can be adjusted by raising and lowering an adjuster star (not shown).

Further, connecting members 4', 4'', and 4 protrude perpendicularly and horizontally from the support base member 3, respectively, and the connecting members are arranged such that the outermost portion 4 thereof faces diagonally upward. It is connected to the supporting base member 3 by integral molding, and the connecting members 4',
A screw hole 8 is vertically penetrated through a part of 4'', 4.

Each of the top plate support rods 2, 2... is provided with a recess 5', a recess 55'', and a recess 5 at its end so as to correspond to the connecting members 4', 4'', 4, and the recesses 5', 5 ″
The upper surface is defined as a first horizontal piece 6', which corresponds to the horizontal surface of the lower surface of the top plate 7, and also has a recess 5.
A rising slope 6'' is defined on the upper surface of the top plate 7, and a second horizontal surface 6 is defined from the upper end of the rising slope 6''.

Fit the connecting members 4', 4'', 4 of the support base member 3 into the recesses 5', 5'', 5 of the top plate support rod 2, respectively, attach the leg tube 1 to the support base member 3, and tighten the fixing nut 18. For example, a frame structure as shown in Fig. 2 can be formed,
By placing the top plate 7 on this frame structure, the lower surface shape of the top plate 7 matches the placement space of the frame structure, and alignment in the front, rear, left, and right directions is achieved. Screw holes 8 are pre-drilled in the top support rod 2, and at the same time as the frame structure is formed, the screw holes in the top support rod 2 and the screw holes in the support base member 3 are aligned. There is.

Therefore, by passing screw 9 from below,
A state in which the top plate support rod 2, support base member 3, and top plate 7 are integrally attached as shown in FIG. 3 is achieved.

Each cross section of each of the top plate support rods 2, 2, .

The top plate 7 has a notch 11, and the supporting base member 3
The structure is such that the nut hole 17 is not covered, a support base cover 10 is attached to cover the notch 11, and a cap body 12 which can be connected with a snap is further covered to cover the opening 19.
