[0008] Hereinafter, the joining structure of members according to this embodiment will be described with reference to the drawings. First Embodiment Fig. 1 is a perspective view showing an example of a structure 10. Fig. 2 is an exploded perspective view showing an example of the structure 10. The structure 10 of this embodiment is used as a framework of a container for logistics, warehouse, residence, etc. The structure 10 is configured in a substantially rectangular parallelepiped shape by joining a plurality of frames.

[0009] The structure 10 has four support members 20a to 20d, four upper frame members 30a to 30d, four lower frame members 40a to 40d, and seven reinforcing frame members 50a to 50g. The support members 20a to 20d are elongated or rod-shaped members extending in the vertical direction. The support members 20a to 20d are axially shaped extending in the longitudinal direction. The support members 20a to 20d are all approximately the same length. The support members 20a to 20d correspond to an example of a first member. The support members 20a to 20d have a hollow, approximately rectangular cross-sectional shape when cut in a direction perpendicular to the longitudinal direction. The cross-sectional shape of the support members 20a to 20d in this embodiment is approximately square. Furthermore, the support members 20a to 20d in this embodiment are made of, for example, metal. However, the shape and material of the support members 20a to 20d are not particularly limited. The support members 20a to 20d are each subjected to processing at their upper and lower ends, which will be described later, and the same material can be used, including the processing.

[0010] The upper frame members 30a to 30d are elongated or rod-shaped members extending horizontally. The upper frame members 30a to 30d are axially shaped along the longitudinal direction. The upper frame members 30a and 30c have approximately the same length, and the upper frame members 30b and 30d have approximately the same length. The upper frame members 30a and 30c are longer than the upper frame members 30b and 30d. The upper frame members 30a to 30d correspond to an example of a second member or a third member. The upper frame members 30a to 30d have a hollow, approximately rectangular cross-section cut in a direction perpendicular to the longitudinal direction. The cross-sections of the upper frame members 30a to 30d of this embodiment are approximately square. Furthermore, both ends of the upper frame members 30a to 30d of this embodiment are linear and perpendicular to the longitudinal direction in a plan view. Furthermore, the upper frame members 30a to 30d of this embodiment are made of, for example, metal. However, the shape and material of the upper frame members 30a to 30d are not particularly limited. Both ends of each of the upper frame members 30a to 30d are processed as described below. The upper frame members 30a and 30c can be made of the same material, including the processing, and the upper frame members 30b and 30d can be made of the same material, including the processing.

[0011] The upper frame member 30a is arranged across the upper end of the support member 20a and the upper end of the support member 20d, the upper frame member 30b is arranged across the upper end of the support member 20a and the upper end of the support member 20b, the upper frame member 30c is arranged across the upper end of the support member 20b and the upper end of the support member 20c, and the upper frame member 30d is arranged across the upper end of the support member 20c and the upper end of the support member 20d.

[0012] The lower frame members 40a to 40d are elongated or rod-shaped members extending horizontally. The lower frame members 40a to 40d are axially shaped along the longitudinal direction. The lower frame members 40a and 40c have approximately the same length, and the lower frame members 40b and 40d have approximately the same length. The lower frame members 40a and 40c are longer than the lower frame members 40b and 40d. The lower frame members 40a to 40d correspond to an example of a second member or a third member. The lower frame members 40a to 40d have a hollow, approximately rectangular cross-section cut in a direction perpendicular to the longitudinal direction. The cross-sections of the lower frame members 40a to 40d of this embodiment are approximately square. Furthermore, both ends of the lower frame members 40a to 40d of this embodiment are linear and perpendicular to the longitudinal direction in a plan view. Furthermore, the lower frame members 40a to 40d of this embodiment are made of, for example, metal. However, the shape and material of the lower frame members 40a to 40d are not particularly limited. Both ends of the lower frame members 40a to 40d are processed in the same manner as the upper frame members 30a to 30d. The lower frame members 40a and 40c can be made of the same material, including the processing, and the lower frame members 40b and 40d can be made of the same material, including the processing.

[0013] The lower frame member 40a is arranged across the lower end of the support member 20a and the lower end of the support member 20d, the lower frame member 40b is arranged across the lower end of the support member 20a and the lower end of the support member 20b, the lower frame member 40c is arranged across the lower end of the support member 20b and the lower end of the support member 20c, and the lower frame member 40d is arranged across the lower end of the support member 20c and the lower end of the support member 20d.

[0014] The reinforcing frame members 50a to 50g are elongated or rod-shaped members extending horizontally. The reinforcing frame members 50a to 50g are all approximately the same length. The reinforcing frame members 50a to 50g have a hollow, approximately rectangular cross-section cut in a direction perpendicular to the longitudinal direction. The reinforcing frame members 50a to 50g of this embodiment are made of, for example, metal. However, the shape and material of the reinforcing frame members 50a to 50g are not particularly limited. The reinforcing frame members 50a to 50g are each disposed at intervals across the lower frame member 40a and the lower frame member 40c.

[0015] Both ends of the upper frame members 30a to 30d are joined to the upper ends of the support members 20a to 20d, and both ends of the lower frame members 40a to 40d are joined to the lower ends of the support members 20a to 20d, forming a substantially rectangular parallelepiped.

[0016] Next, a joining structure in which the support member 20a, the upper frame member 30a, and the upper frame member 30b are joined together will be described as a representative example. FIG. 3 is a perspective view showing the state before the support member 20a, the upper frame member 30a, and the upper frame member 30b are joined together. The support member 20a has four side walls 21a to 21d. The upper end of the support member 20a has a first opening 26 that opens in the longitudinal direction (axial direction) of the support member 20a, and a second opening 27 and a third opening 28 that open in a direction perpendicular to the longitudinal direction.

[0017] The first opening 26 opens upward and is formed because the support member 20a is hollow. The second opening 27 is an opening formed in the side wall 21d. The second opening 27 is a notched opening that is open at the top. The upper frame member 30a can be inserted into the second opening 27 from above. The second opening 27 is formed, for example, by cutting or punching the side wall 21d. The third opening 28 is an opening formed in the side wall 21c. The third opening 28 is a notched opening that is open at the top. The upper frame member 30b can be inserted into the third opening 28 from above. The third opening 28 is formed, for example, by cutting or punching the side wall 21c.

[0018] The upper frame member 30a has two opposing side walls 31a, 31b, an upper wall 31c, and a lower wall 31d. The end of the upper frame member 30a facing the support member 20a has a fourth opening 32 that opens in a direction perpendicular to the longitudinal direction (axial direction) of the upper frame member 30a.

[0019] The fourth opening 32 is an opening formed in the upper wall 31c. In a plan view, the fourth opening 32 is substantially rectangular, and in this case, substantially square. The fourth opening 32 is formed at a position spaced a distance L from an end of the upper frame member 30a. The opening width W of the fourth opening 32 along the longitudinal direction of the upper frame member 30a is greater than the width W3 of the upper frame member 30b. The opening width W of the fourth opening 32 is substantially the same as the opening width W of a fifth opening 37, which will be described later. Furthermore, a pair of slits 33 is formed in each of the side walls 31a and 31b on both sides of the fourth opening 32. The slits 33 are formed at positions extending the four corners of the fourth opening 32 toward the bottom wall 31d. The distance between the two slits 33 formed in each side wall 31a and 31b is substantially the same as the opening width W. A tongue portion 34 is formed between the two slits 33. The upper end of the tongue portion 34 is lower than the upper surface of the upper wall 31c, preferably by approximately the thickness of the upper wall 31c. A pair of slits 33 formed in the side wall 31a and a pair of slits 33 formed in the side wall 31b are positioned perpendicular to the longitudinal direction of the upper frame member 30a. The slits 33 are formed to approximately half the vertical length of each side wall 31a, 31b, preferably to a position beyond half the vertical length. The slit width Ws of each slit 33 is greater than the thickness of side walls 36a, 36b (described later) of the upper frame member 30b.

[0020] The fourth opening 32 and the slit 33 are formed, for example, by cutting or punching the side walls 31a, 31b and the top wall 31c. The upper frame member 30a also has an identical opening formed at the end on the support member 20d side, and this opening is given the same reference numerals as the fourth opening 32 and the slit 33. That is, the same processing can be performed on both ends of the upper frame member 30a, thereby reducing processing costs.

[0021] The upper frame member 30b has two opposing side walls 36a, 36b, an upper wall 36c, and a lower wall 36d. The end of the upper frame member 30b on the support member 20a side has a fifth opening 37 that opens in a direction perpendicular to the longitudinal direction (axial direction) of the upper frame member 30b.

[0022] The fifth opening 37 is an opening formed in the lower wall 36d. In a bottom view, the fifth opening 37 is generally rectangular, and in this case, generally square. The fifth opening 37 is formed at a position spaced a distance L from the end of the upper frame member 30b. The distance L from the end of the upper frame member 30b to the fifth opening 37 is generally the same as the distance L from the end of the upper frame member 30a to the fourth opening 32. The opening width W of the fifth opening 37 along the longitudinal direction of the upper frame member 30b is greater than the width W2 of the upper frame member 30a. The opening width W of the fifth opening 37 is generally the same as the opening width W of the fourth opening 32 described above. In addition, a pair of slits 38 is formed in each of the side walls 36a, 36b of the upper frame member 30b on both sides of the fifth opening 37. The slits 38 are formed at positions where the four corners of the fifth opening 37 extend toward the upper wall 36c. The distance between the two slits 38 formed in each side wall 36a, 36b is approximately the same as the opening width W. A tongue portion 39 is formed between the two slits 38. The lower end of the tongue portion 39 is higher than the lower surface of the bottom wall 36d, preferably by approximately the thickness of the bottom wall 36d. The pair of slits 38 formed in the side wall 36a and the pair of slits 38 formed in the side wall 36b are positioned perpendicular to the longitudinal direction of the upper frame member 30b. The slits 38 are formed to approximately half the vertical length of each side wall 36a, 36b, preferably to a position above that half. The slit width Ws of each slit 38 is greater than the thickness of the side walls 31a, 31b of the upper frame member 30a. The slit width of the slit 38 in the upper frame member 30b is approximately the same as the slit width of the slit 33 in the upper frame member 30a.

[0023] The fifth opening 37 and the slit 38 are formed, for example, by cutting or punching the side walls 36a, 36b and the bottom wall 36d. The upper frame member 30b also has a substantially identical opening formed at its end on the support member 20b side, and this opening is given the same reference numerals as the fifth opening 37 and the slit 38. In other words, substantially the same processing can be performed on both ends of the upper frame member 30b, which reduces processing costs.

[0024] The opening width W of the fourth opening 32 in the upper frame member 30a is approximately the same as the opening width W of the fifth opening 37 in the upper frame member 30b. Furthermore, the slit width of the slit 33 in the upper frame member 30a is approximately the same as the slit width of the slit 38 in the upper frame member 30b. Therefore, the end of the upper frame member 30a facing the support member 20a and the end of the upper frame member 30b facing the support member 20a can be processed in approximately the same manner, thereby reducing processing costs. In other words, by turning the upper frame member 30b upside down, the shape of the end of the upper frame member 30a and the shape of the end of the upper frame member 30b become approximately the same.

[0025] Next, a method for joining the support member 20a and the upper frame members 30a and 30b will be described. First, as shown in Fig. 3, the worker aligns the fourth opening 32 of the upper frame member 30a with the fifth opening 37 of the upper frame member 30b and brings the upper frame members 30a and 30b closer together. Then, the worker fits the pair of slits 33 in the side wall 31a of the upper frame member 30a with one (end face side) of the pair of slits 38 in the side wall 36a of the upper frame member 30b and one (end face side) of the pair of slits 38 in the side wall 36b of the upper frame member 30b. Similarly, the worker fits the pair of slits 33 in the side wall 31b of the upper frame member 30a with the other (opposite end face) of the pair of slits 38 in the side wall 36a of the upper frame member 30b and the other (opposite end face) of the pair of slits 38 in the side wall 36b of the upper frame member 30b. At this time, the tongue portion 34 of the side wall 31a of the upper frame member 30a and the tongue portion 34 of the side wall 31b are inserted into the fifth opening 37 of the upper frame member 30b, and the tongue portion 39 of the side wall 36a of the upper frame member 30b and the tongue portion 39 of the side wall 36b are inserted into the fourth opening 32 of the upper frame member 30a.

[0026] The upper frame members 30a and 30b are joined by fitting them together until the ends of the slits 33 of the upper frame member 30a and the ends of the slits 33 of the upper frame member 30b come into contact. Alternatively, the upper frame members 30a and 30b may be joined together by fitting them together until the tongue portion 34 of the upper frame member 30a comes into contact with the upper wall 36c of the upper frame member 30b and the tongue portion 39 of the upper frame member 30b comes into contact with the lower wall 31d of the upper frame member 30a. When the upper frame members 30a and 30b are joined together, the side walls 36a and 36b of the upper frame member 30b are positioned within the slits 33 of the upper frame member 30a, and the side walls 31a and 31b of the upper frame member 30a are positioned within the slits 33 of the upper frame member 30b. Furthermore, when the upper frame members 30a and 30b are joined together, the upper wall 31c of the upper frame member 30a and the upper wall 36c of the upper frame member 30b are substantially flat with no step. Furthermore, when the upper frame members 30a and 30b are joined together, the lower wall 31d of the upper frame member 30a and the lower wall 36d of the upper frame member 30b are substantially flat with no step.

[0027] Next, as shown in Fig. 4, the worker inserts the upper frame members 30a and 30b, while they are joined together, into the first opening 26 of the support member 20a. At this time, the upper frame member 30a is inserted into the second opening 27 of the support member 20a, and the upper frame member 30b is inserted into the third opening 28 of the support member 20a.

[0028] The upper frame member 30a, the upper frame member 30b, and the support member 20a are joined by inserting the upper frame member 30a and the upper frame member 30b into the first opening 26 of the support member 20a until the lower wall 31d of the upper frame member 30a contacts the lower end of the opening edge of the second opening 27 and the lower wall 36d of the upper frame member 30b contacts the lower end of the opening edge of the third opening 28. When the upper frame member 30a, the upper frame member 30b, and the support member 20a are joined together, the portion where the upper frame member 30a and the upper frame member 30b are joined is located within the first opening 26. Furthermore, when the upper frame member 30a, the upper frame member 30b, and the support member 20a are joined together, the upper frame member 30a is inserted through the second opening 27, and the upper frame member 30b is inserted through the third opening 28.

[0029] In this way, by joining the upper frame members 30a, 30b and the support member 20a, the strength of the joint structure can be improved. Specifically, when a force is applied to the upper frame member 30a in the longitudinal direction toward the support member 20a, the end face of the upper frame member 30a abuts against the side wall 21b of the support member 20a, or the side wall 36a of the upper frame member 30b abuts against the side wall 21b side of the opening edge of the third opening 28. Furthermore, the opening edge of the fourth opening 32 of the upper frame member 30a abuts against the side wall 36b of the upper frame member 30b, or the tongue portion 34 of the upper frame member 30a abuts against the side wall 36a from inside the upper frame member 30b. Conversely, when a force is applied to the upper frame member 30a in the longitudinal direction opposite to the support member 20a, the side wall 36b of the upper frame member 30b abuts against the side wall 21d side of the opening edge of the third opening 28. Furthermore, the opening edge of the fourth opening 32 of the upper frame member 30a abuts against the side wall 36a of the upper frame member 30b, or the tongue portion 34 of the upper frame member 30a abuts against the side wall 36b from inside the upper frame member 30b.

[0030] On the other hand, when a force is applied to the upper frame member 30b in the longitudinal direction toward the support member 20a, the end face of the upper frame member 30b abuts against the side wall 21a of the support member 20a, or the side wall 31a of the upper frame member 30a abuts against the side wall 21a side of the opening edge of the second opening 27. Furthermore, the opening edge of the fifth opening 37 of the upper frame member 30b abuts against the side wall 31b of the upper frame member 30a, or the tongue portion 39 of the upper frame member 30b abuts against the side wall 31a from inside the upper frame member 30a. Conversely, when a force is applied to the upper frame member 30b in the longitudinal direction opposite to the support member 20a, the side wall 31b of the upper frame member 30a abuts against the side wall 21c side of the opening edge of the second opening 27. Furthermore, the opening edge of the fifth opening 37 of the upper frame member 30b abuts against the side wall 31a of the upper frame member 30a, or the tongue portion 39 of the upper frame member 30b abuts against the side wall 31b from inside the upper frame member 30a.

[0031] In this way, even when force is applied to the upper frame members 30a and 30b, the force is not concentrated locally but is dispersed, thereby improving the strength of the joined structure. Note that when force is applied to the upper frame members 30a and 30b, it is not limited to the case where all of the above-mentioned contacts occur, and some of the contacts may not occur.

[0032] Here, we have explained the case of joining upper frame member 30a, upper frame member 30b, and support member 20a, but by joining other parts in the same way, it is possible to join upper frame members 30a to 30d and support members 20a to 20d, and to join lower frame members 40a to 40d and support members 20a to 20d. The state in which the lower frame members 40a to 40d and the support members 20a to 20d are joined is the same as the state in which the upper frame members 30a to 30d and the support members 20a to 20d are joined but turned upside down.

[0033] In this embodiment, the upper frame members 30a, 30c (lower frame members 40a, 40c) are described as being longer than the upper frame members 30b, 30d (lower frame members 40b, 40d), but the upper frame members 30b, 30d (lower frame members 40b, 40d) may be longer than the upper frame members 30a, 30c (lower frame members 40a, 40c) or may be of approximately the same length. In addition, in this embodiment, the case where the joining structure of members is applied to the structure 10 as the skeleton of a container has been described, but the present invention is not limited to this case and may be applied to any structure. For example, the joining structure may be applied to a structure as the skeleton of a table, counter, cart, etc.

[0034] <Second embodiment> 5 is a perspective view showing an example of the structure 11. Note that the description of the same configuration as in the first embodiment will be omitted as appropriate. The structure 11 of this embodiment is used as a frame of a table or the like. The structure 11 is formed into a pentagonal prism shape by joining a plurality of frames. The structure 11 of this embodiment has a substantially regular pentagonal shape in a plan view.

[0035] The structure 11 has five support members 120a to 120e, five upper frame members 130a to 130e, and five lower frame members 140a to 140e. The support members 120a to 120e are elongated or rod-shaped members extending in the vertical direction. The support members 120a to 120e have a hollow, approximately circular cross-section taken in a direction perpendicular to the longitudinal direction. However, the shape and material of the support members 120a to 120e are not particularly limited. The support members 120a to 120e are each processed at their upper and lower ends, as will be described later, and the same material can be used, including the processing.

[0036] The upper frame members 130a to 130e are elongated or rod-shaped members extending horizontally. The upper frame members 130a to 130e have approximately the same length. The upper frame members 130a to 130e have a hollow, approximately rectangular cross section cut in a direction perpendicular to the longitudinal direction. In this embodiment, both ends of the upper frame members 130a to 130e are arc-shaped and convex outward in plan view. The radius of curvature of the arcs at both ends of the upper frame members 130a to 130e is approximately the same as the radius of curvature of the inner circumferential surface of a first opening 126 (described later) of the support members 120a to 120e. However, the shape and material of the upper frame members 130a to 130e are not particularly limited. The upper frame members 130a to 130e are each processed at both ends as described below. The same material can be used for the upper frame members 130a to 130e, including the processing. The lower frame members 140a to 140e have the same configuration as the upper frame members 130a to 130e, and therefore a description thereof will be omitted.

[0037] FIG. 6 is a perspective view showing the state before the support member 120a, the upper frame member 130a, and the upper frame member 130b are joined together. The upper end of the support member 120a has a first opening 126 that opens in the longitudinal direction of the support member 120a, and a second opening 127 and a third opening 128 that open in a direction perpendicular to the longitudinal direction.

[0038] The upper frame member 130a has two opposing side walls 131a and 131b, an upper wall 131c, and a lower wall 131d. The end of the upper frame member 130a on the support member 120a side has a fourth opening 132 that opens in a direction perpendicular to the longitudinal direction of the upper frame member 130a.

[0039] The fourth opening 132 is an opening formed in the upper wall 131c. In a plan view, the fourth opening 132 is substantially a parallelogram. Specifically, two sides of the opening edge of the fourth opening 132 that are located on the upper wall 131c are not perpendicular to the longitudinal direction of the upper frame member 130a, but are inclined at approximately 72° (see the inclination angle α shown in FIG. 6).

[0040] Furthermore, the upper frame member 130a has a pair of slits 133 formed in each of the side walls 131a and 131b on both sides of the fourth opening 132. The slits 133 are formed at positions extending from the four corners of the fourth opening 132 toward the bottom wall 131d. The pair of slits 133 formed in the side wall 131a and the pair of slits 133 formed in the side wall 131b are not positioned perpendicular to the longitudinal direction of the upper frame member 130a, but are positioned obliquely relative to the longitudinal direction of the upper frame member 130a. Specifically, the pair of slits 133 formed in the side wall 131a are positioned closer to the end face of the upper frame member 130a than the pair of slits 133 formed in the side wall 131b. A tongue portion 134 is formed between the two slits 133.

[0041] Furthermore, substantially the same opening is also formed in the lower wall 131d of the end of the upper frame member 130a on the support member 120e side, and is given the same reference numerals as the above-mentioned fourth opening 132 and slit 133. In other words, substantially the same processing can be performed on both end portions of the upper frame member 130a by turning it upside down, thereby reducing processing costs.

[0042] The upper frame member 130b has two opposing side walls 136a, 136b, an upper wall 136c, and a lower wall 136d. The end of the upper frame member 130b on the support member 120a side has a fifth opening 137 that opens in a direction perpendicular to the longitudinal direction of the upper frame member 130b.

[0043] The fifth opening 137 is an opening formed in the lower wall 136d. When viewed from the bottom, the fifth opening 137 is substantially parallelogram-shaped. The upper frame member 130b has a pair of slits 138 formed in each of the side walls 136a, 136b on both sides of the fifth opening 137. A tongue portion 139 is formed between the two slits 138. Here, the fifth opening 137, slit 138, and tongue portion 139 of the upper frame member 130b have approximately the same shapes as the fourth opening 132, slit 133, and tongue portion 134 when the upper frame member 130a is turned upside down, and detailed explanations will be omitted.

[0044] Furthermore, the upper frame member 130b has a substantially identical opening formed in the top wall 136c of the end portion on the support member 120b side, and this opening is given the same reference numerals as the above-mentioned fifth opening 137 and slit 138. That is, by turning the upper frame member 130b upside down, substantially identical processing can be performed on both end portions, thereby reducing processing costs.

[0045] To join the support member 120a and the upper frame member 130a and the upper frame member 130b, they can be joined in the same manner as in the first embodiment, and by joining other parts in the same manner, the upper frame members 130a to 130e can be joined to the support members 120a to 120e, and the lower frame members 140a to 140e can be joined to the support members 120a to 120e. The state in which the lower frame members 140a to 140e and the support members 120a to 120e are joined is the same as the state in which the upper frame members 130a to 130e and the support members 120a to 120e are joined but turned upside down.

[0046] In this embodiment as well, when force is applied to the upper frame members 130a and 130b, the force is not concentrated locally but is dispersed, thereby improving the strength of the joined structure. In this embodiment, the upper frame members 130a to 120e can be made of the same material, including the processing. In this embodiment, the lower frame members 140a to 140e can be made of the same material, including the processing. Furthermore, in this embodiment, the upper frame members 130a to 120e and the lower frame members 140a to 140e can be made of the same material, including the same processing.

[0047] <Third embodiment> 7 is a perspective view showing an example of the structure 12. Note that the description of the same configuration as in the first or second embodiment will be omitted as appropriate, and the description will focus on the differences from the second embodiment. The structure 12 of this embodiment is used as a frame of a table or the like. The structure 12 is formed into a hexagonal prism shape by joining a plurality of frames. The structure 12 of this embodiment has a substantially regular hexagonal shape in a plan view.

[0048] The structure 12 has six support members 220a to 220f, six upper frame members 230a to 230f, six lower frame members 240a to 240f, and reinforcing frame members 250a to 250b.

[0049] The support members 220a to 220f are long or rod-shaped members extending in the vertical direction and have the same configuration as the support members 120a to 120e of the second embodiment. The upper frame members 230a to 230f are long or rod-shaped members extending horizontally, and have the same configuration as the upper frame members 130a to 130e of the second embodiment.

[0050] The lower frame members 240a to 240f have the same configuration as the upper frame members 230a to 230f, and therefore a description thereof will be omitted. Reinforcing frame member 250a is disposed across support member 220a and support member 220d, and reinforcing frame member 250b is disposed across support member 220b and support member 220e.

[0051] FIG. 8 is a perspective view showing the state before the support member 220a, the upper frame member 230a, and the upper frame member 230b are joined together. The upper end of the support member 220a has a first opening 226 that opens in the longitudinal direction of the support member 220a, and a second opening 227 and a third opening 228 that open in a direction perpendicular to the longitudinal direction.

[0052] The upper frame member 230a has a fourth opening 232 that opens in a direction perpendicular to the longitudinal direction of the upper frame member 230a at the end of the upper wall on the support member 220a side, a pair of slits 233 provided in the side walls on both sides of the fourth opening 232, and a tongue portion 234. Two sides of the opening edge of the fourth opening 232 that are located on the upper wall are not perpendicular to the longitudinal direction of the upper frame member 230a, but are inclined at approximately 60° (see inclination angle β shown in FIG. 8).

[0053] Furthermore, substantially the same opening is formed in the lower wall of the end of the upper frame member 230a on the support member 220f side, and is given the same reference numerals as the fourth opening 232 and the slit 233. That is, substantially the same processing can be performed on both end portions of the upper frame member 230a by turning it upside down, thereby reducing processing costs.

[0054] The upper frame member 230b has a fifth opening 237 that opens in a direction perpendicular to the longitudinal direction of the upper frame member 230b at the end of the lower wall on the support member 220a side, and a pair of slits 238 and tongue portions 239 provided in the side walls on both sides of the fifth opening 237. The fifth opening 237, slit 238, and tongue portion 239 of the upper frame member 230b have substantially the same shapes as the fourth opening 232, slit 233, and tongue portion 234 when the upper frame member 230a is turned upside down, and detailed description thereof will be omitted.

[0055] To join the support member 220a and the upper frame member 230a and the upper frame member 230b, they can be joined in the same manner as in the first embodiment, and by joining other parts in the same manner, the upper frame members 230a to 230f can be joined to the support members 220a to 220f, and the lower frame members 240a to 240f can be joined to the support members 220a to 220f.

[0056] The state in which the lower frame members 240a to 240f and the support members 220a to 220f are joined together is the same as the state in which the upper frame members 230a to 230f and the support members 220a to 220f are joined together but turned upside down.

[0057] In this embodiment as well, when force is applied to the upper frame members 230a and 230b, the force is not concentrated locally but is dispersed, thereby improving the strength of the joined structure. In this embodiment, the upper frame members 230a to 220f can be made of the same material, including the processing. In this embodiment, the lower frame members 240a to 240f can be made of the same material, including the processing required. Furthermore, in this embodiment, the upper frame members 230a to 220f and the lower frame members 240a to 240f can be made of the same material, including the same processing.

[0058] The present invention has been described above using the above-mentioned embodiments and examples, but the present invention is not limited to the above-mentioned embodiments and examples, and modifications are possible within the scope of the present invention, and some configurations of each embodiment or modification may be combined with other embodiments or modifications as appropriate. In the above-described embodiment, the members are joined by fitting them together, but the joint may be reinforced by adding screws or nuts, or by welding.

[0059] In the above-described embodiment, the case where the structure for joining members is used in the structures 10, 11, and 12 has been described, but the present invention is not limited to this case and may be used in any way as long as it is used to join members. In the above-described embodiment, the structures 10, 11, and 12 are used as the framework of a container or a table, but they can also be used in glamping facilities, hotels, chairs, shelves, interiors, and the like.
