[0016] Preferred embodiments of the present invention will now be described in detail.

[0017] In describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, the terms described below are defined in consideration of the functions in the present invention, and may vary depending on the intention of a user or operator, legal precedents, etc. Therefore, the definitions should be determined based on the contents of this specification as a whole.

[0018] FIG. 1 is an oblique view showing a first embodiment of an assembly chair according to the present invention, FIG. 2 is an exploded oblique view showing a first frame and a second frame of the present invention disassembled, and FIG. 3 is a oblique view showing a state in which the first frame and the second frame of the present invention are assembled.

[0019] 1 to 3, a knockdown chair 100 according to the present invention generally includes a first frame 110, a second frame 140, a backrest 150, and a seat portion 155. As shown in FIG.

[0020] Here, the first frame 110 and the second frame 140 are assembled in a cross shape of "+".

[0021] The first frame 110 of the present invention is composed of a pair of front and rear first legs 111 and second legs 111a, a first upper horizontal support bar 112 and a second upper horizontal support bar 112a connecting the upper part of the first leg 111 to the upper part of the second leg 111a, an upper bracket 120 connecting the first upper horizontal support bar 112 and the second upper horizontal support bar 112a, a first lower horizontal support bar 113 and a second lower horizontal support bar 113a connecting the lower part of the first leg 111 to the lower part of the second leg 111a, and a lower bracket 130 connecting the first lower horizontal support bar 113 and the second lower horizontal support bar 113a.

[0022] The upper bracket 120 is composed of a pair of first connecting pipe portions 121 and second connecting pipe portions 121a into which the first upper horizontal support bar 112 and the second upper horizontal support bar 112a are respectively fitted in a row, and a first fitting groove portion 122 disposed between the pair of first connecting pipe portions 121 and second connecting pipe portions 121a and having a structure that is open downward so that the third upper horizontal support bar 142 can be fitted in.

[0023] The lower bracket 130 is composed of a pair of third connecting pipe portions 131 and fourth connecting pipe portions 131a into which the first lower horizontal support bar 113 and the second lower horizontal support bar 113a are respectively fitted in a row, and a second fitting groove portion 132 disposed between the pair of third connecting pipe portions 131 and fourth connecting pipe portions 131a and having an upwardly open structure into which the third lower horizontal support bar 143a is fitted.

[0024] The second frame 140 of the present invention is composed of a pair of front and rear third legs 141 and fourth legs 141a, a third upper horizontal support bar 142 connecting the upper part of the third leg 141 and the upper part of the fourth leg 141a, and a third lower horizontal support bar 143a connecting the lower part of the third leg 141 and the lower part of the fourth leg 141a.

[0025] The process of assembling the first and second frames will be described with reference to Fig. 3. With the second frame laid on an incline, it is inserted into the space between the first and second upper horizontal support bars and the first and second lower horizontal support bars of the first frame. Then, with the third upper horizontal support bar of the second frame placed in the fitting groove of the upper bracket, the third lower horizontal support bar of the second frame is pulled to forcibly fit into the fitting groove of the lower bracket, completing the assembly.

[0026] In this case, the upper and lower horizontal support bars of the first frame are connected through an upper bracket and a lower bracket, respectively, and have an elastic structure that allows clearance up and down when the third lower horizontal support bar is pulled, making the above-mentioned forced insertion possible.

[0027] FIG. 4 is a diagram showing a structure in which the first frame of the present invention is disassembled into left and right parts based on a bracket, and FIG. 5 is a diagram showing a state in which the first frame of the present invention is assembled with the second frame in a partially disassembled state.

[0028] Referring to Figures 4 and 5, the first frame 110 of the present invention has a structure in which an upper bracket 120 is separated from a first upper horizontal support bar 112 and a second upper horizontal support bar 112a, and a lower bracket 130 is separated from a first lower horizontal support bar 113 and a second lower horizontal support bar 113a.

[0029] 3, the first frame 110 can be assembled with the second frame 140 after either the left or right side is disassembled based on the upper bracket 120 and the lower bracket 130. In this case, the second upper horizontal support bar 112a and the second lower horizontal support bar 113a become free ends that move up and down relatively smoothly, so that they can be more easily assembled with the second frame 140.

[0030] After the third upper horizontal support bar 142 and the third lower horizontal support bar 143a of the second frame 140 are respectively fitted into the first fitting groove portion 122 of the upper bracket 120 and the second fitting groove portion 132 of the lower bracket 130, the first upper horizontal support bar 112 and the first lower horizontal support bar 113 are inserted into the first connecting pipe portion 121 and the third connecting pipe portion 131 and fixed with fastening members 123 such as bolts.

[0031] FIG. 6 is a perspective view showing a second embodiment of the assembly chair according to the present invention, and FIG. 7 is a perspective view showing the state in which the first frame and the second frame of FIG. 6 are assembled.

[0032] 6 and 7, the present embodiment provides a structure for facilitating the process of forcibly fitting together the frames in the first embodiment.

[0033] First, the first frame 110 includes a pair of front and rear legs, a first leg 111 and a second leg 111a, a first upper horizontal support bar 112 and a second upper horizontal support bar 112a connecting the upper part of the first leg 111 to the upper part of the second leg 111a, an upper bracket 120a connecting the first upper horizontal support bar 112 and the second upper horizontal support bar 112a, and a first lower horizontal support bar 113 connecting the lower part of the first leg 111 to the lower part of the second leg 111a.

[0034] The second frame 140 includes a pair of front and rear third legs 141 and fourth legs 141a, a third upper horizontal support bar 142 connecting the upper part of the third leg 141 to the upper part of the fourth leg 141a, a second lower horizontal support bar 143 and a third lower horizontal support bar 143a connecting the lower part of the third leg 141 to the lower part of the fourth leg 141a, and a lower bracket 130a connecting the second lower horizontal support bar 143 and the third lower horizontal support bar 143a.

[0035] Here, the upper bracket 120a is composed of a pair of first connecting pipe portions 121 and second connecting pipe portions 121a into which the first upper horizontal support bar 112 and the second upper horizontal support bar 112a are respectively fitted in a row, and a third fitting groove portion 122a that is disposed between the pair of first connecting pipe portions 121 and second connecting pipe portions 121a and has a structure that is open downward so that the third upper horizontal support bar 142 can be fitted in.

[0036] The lower bracket 130a is composed of a pair of third connecting pipe portions 131 and fourth connecting pipe portions 131a into which the second lower horizontal support bar 143 and the third lower horizontal support bar 143a are respectively fitted in a row, and a fourth fitting groove portion 132a that is disposed between the pair of third connecting pipe portions 131 and fourth connecting pipe portions 131a and has a structure that is open downward so that the first lower horizontal support bar 113 can be fitted in.

[0037] That is, compared to the first embodiment, there is a difference in that an upper bracket joining structure is formed on the first frame, and a lower bracket joining structure is formed on the second frame.

[0038] The assembly process will be described as follows. With the second frame 140 laid on an incline, it is inserted into the space between the first upper horizontal support bar 112 and the second upper horizontal support bar 112a and the first lower horizontal support bar 113 of the first frame 110. With the third upper horizontal support bar 142 of the second frame 140 placed in the third insertion groove 122a of the upper bracket 120a, the second lower horizontal support bar 143 and the third lower horizontal support bar 143a of the second frame 140 are pulled to be coupled to the first lower horizontal support bar 113. At this time, since the fourth insertion groove 132a of the lower bracket 130a provided on the second frame 140 has a structure corresponding to the length direction of the first lower horizontal support bar of the first frame 110, it can be more easily coupled than the first embodiment described above.

[0039] That is, in this embodiment, the lower bracket formed on the second frame serves as a guide rail for the first lower horizontal support bar of the first frame, making assembly easier.

[0040] FIG. 8 is a diagram showing a third embodiment of an assembly chair according to the present invention, and FIG. 9 is a diagram showing a state in which each frame of FIG. 8 is assembled.

[0041] 8 and 9, the assembly chair according to this embodiment has a first frame 110 and a second frame 140 crossed and connected in a “+” shape, and the first frame 110 includes a pair of front and rear first legs 111 and second legs 111a, a first upper horizontal support bar 112 connecting the upper part of the first leg 111 to the upper part of the second leg 111a, an upper bracket 120 formed in the center of the first upper horizontal support bar 112, a first lower horizontal support bar 113 connecting the lower part of the first leg 111 to the lower part of the second leg 111a, and a lower bracket 130 formed in the center of the first lower horizontal support bar 113.

[0042] Here, the upper bracket 120 and the lower bracket 130 may be structured to be connected to the upper horizontal support bar and the lower horizontal support bar as in the above-mentioned embodiment, or of course, may be configured as an integrated type as shown in the figure.

[0043] The second frame 140 includes a pair of front and rear third legs 141 and fourth legs 141a, a second upper horizontal support bar 142 connecting the upper part of the third leg 141 and the upper part of the fourth leg 141a, and a second lower horizontal support bar 143 connecting the lower part of the third leg 141 and the lower part of the fourth leg 141a.

[0044] The second upper horizontal support bar 142 is fitted into the upper bracket 120 , and the second lower horizontal support bar 143 is fitted into the lower bracket 130 .

[0045] In this embodiment, unlike the above-described embodiment, one side of the second lower horizontal support bar is formed with a fitting guide groove portion having a recessed structure on the upper side.

[0046] For example, in the first embodiment, as shown in Fig. 3, the second frame is inserted into the first frame at an angle and then pulled to perform assembly, but in this embodiment, the second frame 140 is fitted into the first frame 110. First, the second frame 140 is fitted through the fitting guide groove portion 145, which has a narrow vertical gap, and then, with the second upper horizontal support bar 142 connected to the upper bracket 120, the second frame 140 is pulled to one side so that the second lower horizontal support bar 143 is connected to the lower bracket 130, completing the frame assembly.

[0047] However, in FIG. 9, the fitting guide grooves 145, 115 are formed in the first frame as well as the second frame, in order to form a symmetrical structure and improve aesthetic appeal.

[0048] As described above, this embodiment has an advantage that the assembly process can be easily performed by a simple process of forming the fitting guide groove portion in the second frame.

[0049] FIG. 10 is a perspective view showing a fourth embodiment of the assembly chair according to the present invention.

[0050] 10, in comparison with the first embodiment described above, this embodiment is different in the structures of the upper bracket 120 and the lower bracket 130. As shown in FIG.

[0051] The upper bracket 120 is composed of a pair of first connecting pipe portions 121 and second connecting pipe portions 121a into which the first upper horizontal support bar 112 and the second upper horizontal support bar 112a are respectively fitted in a row, and a first fitting groove portion 122' disposed between the pair of first connecting pipe portions 121 and second connecting pipe portions 121a and having an upwardly open structure into which the third upper horizontal support bar 142 is fitted.

[0052] The lower bracket 130 is composed of a pair of third connecting pipe portions 131 and fourth connecting pipe portions 131a into which the first lower horizontal support bar 113 and the second lower horizontal support bar 113a are respectively fitted in a row, and a second fitting groove portion 132' disposed between the pair of third connecting pipe portions 131 and fourth connecting pipe portions 131a and having a structure that is open downward so that the third lower horizontal support bar 143a can be fitted in.

[0053] That is, the fitting groove of the upper bracket may be modified to have an upper open structure, and the fitting groove of the lower bracket may be modified to have a lower open structure.

[0054] In this case, the third upper horizontal support bar is placed above the first and second upper horizontal support bars, and the third lower horizontal support bar is placed below the first and second lower horizontal support bars, and then the third upper and lower horizontal support bars of the second frame are forcibly fitted into each bracket. At this time, the upper bracket is slightly bent downward and the lower bracket is slightly bent upward.

[0055] Meanwhile, this embodiment is different from the third embodiment in that the first frame and the second frame are formed with fitting guide protrusions 117 and 147 instead of fitting guide grooves, respectively. This is because the assembly is performed in a state where the first frame is fitted into the second frame due to a structural change in the upper bracket and the lower bracket.

[0056] In this way, the insertion guide groove portion or the insertion guide protrusion portion formed on the second frame narrows or widens the vertical gap between the upper horizontal support bar and the lower horizontal support bar, thereby facilitating assembly with the first frame.

[0057] The present invention described above is merely illustrative, and it should be understood that various modifications and equivalent embodiments are possible for those skilled in the art to which the present invention pertains. Therefore, it should be understood that the present invention is not limited to the forms mentioned in the above detailed description. Therefore, the true technical scope of protection of the present invention should be determined by the technical ideas of the claims. It should also be understood that the present invention includes all modifications, equivalents, and alternatives within the spirit and scope of the present invention defined by the claims.

[0058] Embodiment The embodiments for carrying out the invention have been described together in the above best mode for carrying out the invention. [Industrial Applicability]

[0059] The present invention is composed of two frames that are assembled by crossing in a "+" shape, so that the volume can be significantly reduced when packed, making it easy to store and transport, and it can be easily assembled without additional tools, making it industrially applicable.
