[0036] The present invention can be implemented with various modifications, and specific embodiments are illustrated in the drawings and described in detail. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0037] In describing each drawing, similar reference numerals have been used for similar components. In describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions could obscure the essence of the invention.

[0039] The present invention allows table legs to be attached to tabletops of various shapes and sizes, and not only is assembly and disassembly easy, but the weight can also be reduced.

[0040] The assembly table according to the present invention, having a vertical load, anti-shake, and durable fastening structure, comprises a top plate (10) that can be manufactured in various shapes and sizes, and a top plate support frame (20) composed of a hollow tubular body installed on the bottom surface of the top plate to support legs.

[0041] The upper plate support frame (20) is joined through a leg (30) and a bracket (40), and the bracket (40) is joined to the upper plate support frame (20) by having a frame fixing groove (40g), and the leg (30) is firmly joined to the bracket by having a bracket insertion groove (30g) formed therein.

[0042] Specifically, the bracket (40) has a frame fixing wing (42) and a frame side wall insertion groove (42g) formed therein to strengthen the connection with the top plate support frame (20), and the frame fixing projection (43) increases stability when connected.

[0043] In addition, the top plate fixing wing (41) formed on the bracket (40) is designed to assist in the connection between the top plate (10) and the bracket (40).

[0044] The material, dimensions, joining method, and assembly procedure of each of the above components are as follows.

[0045] The top plate (10) is made of wood, metal, or plastic material, and its size and shape can be varied according to the purpose of use. The top plate support frame (20) is in the form of a hollow tubular body and is made of aluminum alloy or steel to ensure strength and lightness. The legs (30) are connected to each corner of the top plate support frame (20) and are securely fixed through brackets (40).

[0046] The above bracket (40) is a coupling means for coupling the legs to the top plate and the top plate support frame, and as shown in FIGS. 6 and 7, a frame fixing groove (40g) into which the top plate support frame is fitted is formed so that the top plate support frame is fitted and coupled. (See FIGS. 1, 4 and 5)

[0047] The above bracket (40) is made of metal, and the dimensions and positions of the frame fixing wing (42), the frame side wall insertion groove (42g), the frame fixing projection (43), and the top plate fixing wing (41) are designed to provide optimal stability when combined as shown in the drawing. The assembly method involves first positioning the top plate support frame (20) on the bottom surface of the top plate (10), and then using the bracket (40) to combine the leg (30) with the top plate support frame (20).

[0048] At this time, the frame fixing wing (42) and the frame side wall insertion groove (42g) are engaged to increase the coupling strength, and the frame fixing projection (43) prevents shaking of the coupling part. (See FIG. 5, FIG. 8, FIG. 9)

[0049] Finally, by fixing the top plate fixing wing (41) to the top plate (10), the bracket (40) is more firmly attached to the top plate, ensuring stability.

[0050] The prefabricated table of the present invention can be manufactured in various sizes and shapes by the configuration and assembly method described above, and provides stable support even during use.

[0051] The prefabricated table of the present invention has a lightweight structure in which the top plate support frame (20) is composed of a hollow tube. The hollow tube is made of metal or high-strength plastic material and is hollow inside, thereby reducing weight while maintaining sufficient strength.

[0052] The above-mentioned top plate support frame (20) includes a standardized coupling part so as to be combined with various types of top plates, and, for example, a bolt and nut fastening method or a clip coupling method may be applied.

[0053] The above top plate (10) can be manufactured in various materials and shapes such as wood, metal, and glass, and is designed to be compatible with the joint of the top plate support frame, thereby simultaneously satisfying the lightweighting of the assembly table and compatibility with various top plates.

[0054] In addition, the prefabricated table of the present invention can provide both lightweighting and durability by having legs (30) made of hollow tubular bodies. The hollow tubular bodies are formed of metal or high-strength synthetic resin material, and the interior is composed of walls of a certain thickness to provide resistance to impact.

[0055] The top plate support frame (20) is firmly connected to the top of the leg (30) to stably support the top plate, and the bracket (40) is installed between the leg and the top plate support frame to improve structural rigidity, thereby ensuring the overall strength and durability of the assembly table and allowing the user to easily assemble and disassemble it.

[0056] As described above, the prefabricated table of the present invention includes a bracket (40) for securely connecting the leg (30) and the top plate support frame (20).

[0057] The above bracket (40) is equipped with a frame fixing groove (40g), and a top plate support frame is fitted into the frame fixing groove and coupled, and a bracket is fitted into the bracket insertion groove (40g) formed in the leg and coupled.

[0058] The assembly structure described above allows the bracket to be easily inserted and fixed to the legs and the top plate support frame during assembly, making assembly and disassembly easy. The dimensions and shape of the bracket and the groove are optimized to ensure joint strength while allowing the user to easily assemble and disassemble without the need for separate tools.

[0059] The prefabricated table of the present invention consists of a tabletop support frame, a bracket, and a frame fixing wing.

[0060] The above-mentioned frame fixing wing (42) is formed integrally with the bracket and has a structure that is fixed to the top plate support frame. Specifically, the frame fixing wing (42) is formed by being continuously flexible on the side of the bracket, and is inserted and coupled to the corresponding fixing part of the top plate support frame during assembly. This coupling structure effectively prevents shaking of the top plate support frame and maintains a firm fixation even after assembly. In addition, the material of the frame fixing wing is selected as a metal material with excellent durability, so that no deformation or damage occurs even with repeated assembly and disassembly.

[0061] The assembly method involves first inserting the frame fixing wing, which is integrally formed with the bracket, into the fixing part of the tabletop support frame, and then securely joining them using fixing bolts or clips. This ensures both simple assembly and a stable structure for the modular table.

[0062] The prefabricated table of the present invention includes a frame side wall insertion groove (42g) formed on the side of the bracket. This frame side wall insertion groove (42g) is designed to strengthen the connection with the top plate support frame and serves to increase the stability of the top plate support frame when connected.

[0063] Specifically, the frame side wall insertion groove (42g) is formed as a groove with a depth of 5mm and a width of 3mm between the side wall of the frame insertion groove of the bracket and the frame fixing wing, and is coupled by engaging with the corresponding protrusion of the top plate support frame. This coupling structure prevents slipping between the bracket and the top plate support frame during assembly and improves the strength of the entire table.

[0064] The assembly table of the present invention has a frame fixing projection (43) formed at one end of a frame fixing groove (40g) formed in a bracket connecting the top plate support frame and the legs. When combined with the bracket, the frame fixing projection (43) strengthens the bonding force between the top plate support frame and the legs and serves to prevent the bracket from shaking.

[0065] Specifically, the frame fixing projection (43) is formed in a protruding shape at one end of the frame fixing groove (40g) formed in the bracket, and is fixed by being inserted into the fixing hole (20g) formed in the top plate support frame. This improves the structural stability of the assembly table and prevents shaking or detachment that may occur during use. The size, shape, and position of the frame fixing projection can be optimized according to the material and structure of the bracket, the top plate support frame, and the legs, and various modifications are possible within the scope of the present invention.

[0066] The prefabricated table of the present invention includes a top plate fixing wing (41) that assists in the connection between the top plate and the bracket.

[0067] The above-mentioned top plate fixing wing (41) is formed on both sides of the bracket (40) to assist in the connection between the bottom surface of the top plate and the bracket (40), and is designed so that the top plate is stably fixed without shaking when connected to the bracket, so that it is inserted between the top plate and the bracket to increase the connection strength and increase the frictional force of the connection part to prevent shaking.

[0068] The prefabricated table of the present invention is designed so that the legs and the tabletop support frame are firmly joined to prevent bending caused by vertical load.

[0069] Specifically, the legs and the top plate support frame are secured using metal bolts and nuts, and high-strength reinforcing plates are inserted at the joints to maximize the load distribution effect.

[0070] In addition, the top plate support frame (20) has a rubber pad attached to the joint surface with the leg to absorb vibration and shock, and an anti-slip pad is installed on the bottom of the leg to increase stability. This structure effectively supports the vertical load generated during table use to prevent bending, and is designed to be easy to assemble and disassemble, providing convenience to the user.

[0071] The prefabricated table of the present invention configured as described above is used with the legs (30) assembled on the bottom surface of the tabletop as shown in FIGS. 1 and 2, and when not in use, the legs and brackets are separated as shown in FIG. 3 and stored between the tabletop support frames fixed to the tabletop, thereby reducing the space occupied by the entire disassembled prefabricated table.

[0072] The disassembled prefabricated table shown in Fig. 3 can be stored and transported by stacking it in multiple layers as shown in Fig. 13.

[0073] The prefabricated table of the present invention satisfies the technical features of the claim in that it effectively prevents bending caused by vertical loads that may occur during table use, is easy to assemble and disassemble, and provides convenience for the storage and transportation of components. Accordingly, this embodiment clarifies that it is possible to implement a prefabricated table equipped with a stable support structure and a space-efficient storage method.
