[0029] The preferred embodiments of the present invention will now be described in detail.

[0030] In describing this invention, detailed descriptions of known functions or configurations will be omitted if it is determined that such descriptions unnecessarily obscure the essence of the invention. Furthermore, the terminology described below is defined in consideration of the functions in this invention and may vary depending on the intent of the user or operator or precedent. Therefore, definitions should be based on the entire contents of this specification.

[0031] Figure 1 This is a perspective view of a first embodiment of a prefabricated chair according to the present invention. Figure 2 This is an exploded perspective view of the first and second frames of the present invention. Figure 3 This is an assembled perspective view of the first frame and the second frame of the present invention.

[0032] Reference Figures 1 to 3 The prefabricated chair 100 according to the present invention mainly includes a first frame 110, a second frame 140, a backrest 150 and a seat cushion 155.

[0033] At this point, the first frame 110 and the second frame 140 are assembled in a "+" shape.

[0034] The first frame 110 of the present invention includes a pair of first legs 111 and second legs 111a, a first upper horizontal support rod 112 and a second upper horizontal support rod 112a connecting the upper parts of the first legs 111 and the second legs 111a, an upper bracket 120 connecting the first upper horizontal support rod 112 and the second upper horizontal support rod 112a, a first lower horizontal support rod 113 and a second lower horizontal support rod 113a connecting the lower parts of the first legs 111 and the second legs 111a, and a lower bracket 130 connecting the first lower horizontal support rod 113 and the second lower horizontal support rod 113a.

[0035] The upper bracket 120 is composed of a pair of first connecting tubes 121 and second connecting tubes 121a and a first insertion slot 122. The pair of first connecting tubes 121 and second connecting tubes 121a are used for the first upper horizontal support rod 112 and the second upper horizontal support rod 112a to be inserted in a row respectively. The first insertion slot 122 is installed between the pair of first connecting tubes 121 and second connecting tubes 121a and is formed into a downward open structure for the third upper horizontal support rod 142 to be inserted.

[0036] The lower support 130 is composed of a pair of third connecting pipe sections 131 and a fourth connecting pipe section 131a and a second insertion slot section 132. The pair of third connecting pipe sections 131 and the fourth connecting pipe section 131a are used for the first lower horizontal support rod 113 and the second lower horizontal support rod 113a to be inserted in a row respectively. The second insertion slot section 132 is installed between the pair of third connecting pipe sections 131 and the fourth connecting pipe section 131a and is formed as an upward-open structure for the third lower horizontal support rod 143a to be inserted.

[0037] The second frame 140 of the present invention includes a pair of third legs 141 and fourth legs 141a, a third upper horizontal support rod 142 connecting the upper part of the third legs 141 and fourth legs 141a, and a third lower horizontal support rod 143a connecting the lower part of the third legs 141 and fourth legs 141a.

[0038] refer to Figure 3 To understand the assembly process of the first and second frames, the second frame is inserted, with its tilted position, between the first and second upper horizontal support rods and the first and second lower horizontal support rods of the first frame. Then, with the third upper horizontal support rod of the second frame installed into the insertion slot of the upper bracket, the third lower horizontal support rod of the second frame is pulled in and barely inserted into the insertion slot of the lower bracket, thus completing the assembly.

[0039] At this time, since the upper and lower horizontal support rods of the first frame are connected by an upper bracket and a lower bracket respectively, when the third lower horizontal support rod is pulled, the above-mentioned forced insertion can be achieved due to the elastic structure with gaps between the upper and lower parts.

[0040] Figure 4 This is a schematic diagram of the first frame of the present invention, disassembled from the support in the left and right directions. Figure 5 This is a diagram showing the state of the first frame of the present invention when it is partially decomposed and assembled with the second frame.

[0041] Reference Figure 4 and Figure 5In the first frame 110 of the present invention, the upper bracket 120 is separated from the first upper horizontal support rod 112 and the second upper horizontal support rod 112a, and the lower bracket 130 is separated from the first lower horizontal support rod 113 and the second lower horizontal support rod 113a.

[0042] Therefore, compared with the above Figure 3 The assembly process differs from that of the second frame 140. The first frame 110 is assembled with the second frame 140 while it is detached from either the left or right side relative to the upper bracket 120 and the lower bracket 130. In this case, the second upper horizontal support rod 112a and the second lower horizontal support rod 113a become free ends that can move up and down relatively smoothly, thus making it easier to assemble with the second frame 140.

[0043] The third upper horizontal support rod 142 and the third lower horizontal support rod 143a of the second frame 140 are respectively inserted into the first insertion slot 122 and the second insertion slot 132 of the upper bracket 120 and the lower bracket 130. Then, the first upper horizontal support rod 112 and the first lower horizontal support rod 113 are inserted into the first connecting pipe 121 and the third connecting pipe 131 and fixed by fastening members 123 such as bolts.

[0044] Figure 6 To illustrate a perspective view of a second embodiment of the prefabricated chair according to the present invention, Figure 7 for Figure 6 A three-dimensional view of the first and second frames after assembly.

[0045] Reference Figure 6 and Figure 7 This embodiment proposes a structure that facilitates assembly by forcibly inserting the frames as described in the first embodiment above.

[0046] First, the first frame 110 includes a pair of first legs 111 and second legs 111a, a first upper horizontal support rod 112 and a second upper horizontal support rod 112a connecting the upper parts of the first legs 111 and the second legs 111a, an upper bracket 120a connecting the first upper horizontal support rod 112 and the second upper horizontal support rod 112a, and a first lower horizontal support rod 113 connecting the lower parts of the first legs 111 and the second legs 111a.

[0047] The second frame 140 includes a pair of third legs 141 and fourth legs 141a, a third upper horizontal support rod 142 connecting the upper part of the third legs 141 and fourth legs 141a, a second lower horizontal support rod 143 and a third lower horizontal support rod 143a connecting the lower part of the third legs 141 and fourth legs 141a, and a lower bracket 130a connecting the second lower horizontal support rod 143 and the third lower horizontal support rod 143a.

[0048] At this time, the upper bracket 120a is composed of a pair of first connecting tubes 121 and second connecting tubes 121a and a third insertion slot 122a. The pair of first connecting tubes 121 and second connecting tubes 121a are used for the first upper horizontal support rod 112 and the second upper horizontal support rod 112a to be inserted in rows respectively. The third insertion slot 122a is installed between the pair of first connecting tubes 121 and second connecting tubes 121a and is formed into a downward-open structure for the third upper horizontal support rod 142 to be inserted.

[0049] The lower support 130a is composed of a pair of third connecting pipe sections 131 and a fourth connecting pipe section 131a and a fourth insertion slot section 132a. The pair of third connecting pipe sections 131 and the fourth connecting pipe section 131a are used for the second lower horizontal support rod 143 and the third lower horizontal support rod 143a to be inserted in a row respectively. The fourth insertion slot section 132a is installed between the pair of third connecting pipe sections 131 and the fourth connecting pipe section 131a and is formed into a downward open structure for the first lower horizontal support rod 113 to be inserted.

[0050] That is, compared with the first embodiment, the difference is that the upper support connecting structure is formed in the first frame and the lower support connecting structure is formed in the second frame.

[0051] From the assembly process, the second frame 140 is inserted into the space between the first upper horizontal support rod 112 and the second upper horizontal support rod 112a and the first lower horizontal support rod 113 of the first frame 110 while tilted. Then, with the third upper horizontal support rod 142 of the second frame 140 installed in the third insertion slot 122a of the upper bracket 120a, the second lower horizontal support rod 143 and the third lower horizontal support rod 143a of the second frame 140 are pulled in and connected to the first lower horizontal support rod 113. At this time, since the fourth insertion slot 132a of the lower bracket 130a provided in the second frame 140 has a structure corresponding to the length direction of the first lower horizontal support rod of the first frame 110, it can be easily combined compared with the first embodiment described above.

[0052] That is, in this embodiment, since the lower bracket formed on the second frame acts as the guide rail for the first lower horizontal support rod of the first frame, it is easy to assemble.

[0053] Figure 8 This is a schematic diagram of a third embodiment of the prefabricated chair according to the present invention. Figure 9 for Figure 8 A schematic diagram of the assembly of each frame.

[0054] See Figure 8 and Figure 9According to this embodiment, the prefabricated chair is formed by a first frame 110 and a second frame 140 intersecting in a "+" shape. The first frame 110 includes a pair of first legs 111 and second legs 111a, a first upper horizontal support rod 112 connecting the upper part of the first legs 111 and the second legs 111a, an upper bracket 120 formed at the center of the first upper horizontal support rod 112, a first lower horizontal support rod 113 connecting the lower part of the first legs 111 and the second legs 111a, and a lower bracket 130 formed at the center of the first lower horizontal support rod 113.

[0055] At this time, the upper bracket 120 and the lower bracket 130 can have the structure combined with the upper horizontal support rod and the lower horizontal support rod as in the aforementioned embodiment, as shown in the figure, or they can be configured as a single piece.

[0056] The second frame 140 includes a pair of third legs 141 and fourth legs 141a, a second upper horizontal support rod 142 connecting the upper part of the third legs 141 and fourth legs 141a, and a second lower horizontal support rod 143 connecting the lower part of the third legs 141 and fourth legs 141a.

[0057] The second upper horizontal support rod 142 is inserted into the upper bracket 120, and the second lower horizontal support rod 143 is inserted into the lower bracket 130.

[0058] In this embodiment, unlike the previous embodiments, the second lower horizontal support rod has an insertion guide groove with an upward-facing recessed structure on one side.

[0059] For example, in the case of the first embodiment, such as Figure 3 As shown, the second frame is inserted into the first frame while tilted, and then pulled to complete the assembly. However, in this embodiment, after the second frame 140 is inserted into the first frame 110, it is first inserted through the insertion guide groove 145 with a narrow vertical spacing. Then, with the second upper horizontal support rod 142 connected to the upper bracket 120, the second frame 140 is pulled to one side to connect the second lower horizontal support rod 142 to the lower bracket 130 to complete the frame assembly.

[0060] However, in Figure 9 In the middle, the insertion guide grooves 145 and 115 are formed in the first frame and the second frame, which is to improve the aesthetics by forming a left-right symmetrical structure.

[0061] Therefore, this embodiment has the advantage of being able to easily perform the assembly process by forming an insertion guide groove in the second frame.

[0062] Figure 10 A perspective view showing a fourth embodiment of the prefabricated chair according to the present invention.

[0063] Reference Figure 10 The structures of the upper support 120 and the lower support 130 in this embodiment differ from those in the first embodiment.

[0064] The upper bracket 120 consists of a pair of first connecting pipe sections 121 and second connecting pipe sections 121a and a first insertion slot section 122'. The pair of first connecting pipe sections 121 and second connecting pipe sections 121a are used for the first upper horizontal support rod 112 and the second upper horizontal support rod 112a to be inserted in a row respectively. The first insertion slot section 122' is installed between the pair of first connecting pipe sections 121 and second connecting pipe sections 121a and is formed into an upward-open structure for the third upper horizontal support rod 142 to be inserted.

[0065] The lower bracket 130 is composed of a pair of third connecting pipe sections 131 and a fourth connecting pipe section 131a and a second insertion slot section 132'. The pair of third connecting pipe sections 131 and the fourth connecting pipe section 131a are used for the first lower horizontal support rod 113 and the second lower horizontal support rod 113a to be inserted in a row respectively. The second insertion slot section 132' is installed between the pair of third connecting pipe sections 131 and the fourth connecting pipe section 131a and is formed into a downward open structure for the third lower horizontal support rod 143a to be inserted.

[0066] That is, the insertion slot of the upper bracket can be an open structure on the upper side, and the insertion slot of the lower bracket can be changed to an open structure on the lower side.

[0067] In this case, the third upper horizontal support rod is positioned above the first upper horizontal support rod and the second upper horizontal support rod, and the third lower horizontal support rod is placed below the first lower horizontal support rod and the second lower horizontal support rod. Then, the third upper horizontal support rod and the third lower horizontal support rod of the second frame are barely inserted into their respective brackets. At this time, the upper bracket bends slightly downward and the lower bracket bends slightly upward.

[0068] Meanwhile, this embodiment differs from the third embodiment in that insertion guide protrusions 117 and 147 are formed in the first frame and the second frame, respectively, instead of insertion guide grooves. This is because, due to the structural changes of the upper and lower supports, assembly is performed when the first frame is inserted into the second frame.

[0069] Therefore, the insertion guide groove or insertion guide protrusion formed on the second frame narrows or widens the vertical gap between the upper and lower horizontal support rods, thereby enabling smooth assembly with the first frame.

[0070] The above description of the present invention is merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible. Therefore, it should be understood that the present invention is not limited to the forms mentioned in the detailed description above. Consequently, the scope of protection of the present invention should be determined by the technical concept of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.

[0072] The methods for carrying out the present invention have been described together with the best methods for carrying out the present invention described above.

[0073] Industrial utilization potential

[0074] Since the present invention is assembled by two frames in a "+" shape, the volume can be significantly reduced during packaging, making it easy to store and transport. It can also be easily assembled even without the need for separate tools, thus having industrial applicability.
