Modes for Carrying Out the Invention

[0008] Hereinafter, the assembly tool of the embodiment will be described in detail with reference to the drawings.

[0009] In the following drawings and the like, the positions, sizes, shapes, ranges, etc. of the respective components shown may not represent the actual positions, sizes, shapes, ranges, etc. for the purpose of facilitating the understanding of the invention. Therefore, the present invention is not necessarily limited to the positions, sizes, shapes, ranges, etc. disclosed in the drawings and the like. Elements represented in the singular form in the embodiments shall include the plural form unless otherwise clearly indicated in the text. <Embodiment> FIG. 1 is a view showing the assembly tool of the embodiment. FIG. 2 is a view when the top plate of the assembly tool of the embodiment is removed. The assembly tool 100 can be applied to, for example, furniture, toys, camping supplies (such as the frame structure of a tent), and the like.

[0010] The assembly tool 100 of the embodiment includes a top plate 10, four rod-shaped bodies 1, four support columns 2, four cross bars 3, and eight joints 4. The rod-shaped body 1 is an example of a first rod-shaped body. The support column 2 is an example of a second rod-shaped body. The cross bar 3 is an example of a third rod-shaped body. The joint 4 is an example of an attachment tool. The top plate 10, the rod-shaped body 1, the support column 2, and the cross bar 3 can be formed of, for example, wood or resin. The joint 4 can be formed by bending a single long body and can be formed of, for example, metal or resin.

[0011] The rod-shaped body 1, the support column 2, and the cross bar 3 are fixed to each other by the joint 4. The rod-shaped body 1, the support column 2, and the cross bar 3 can be easily fixed by assembling the rod-shaped body 1 to the joint 4 with the joint 4 attached to the support column 2 and the cross bar 3. Also, the support column 2 and the cross bar 3 can be easily separated by pulling out the rod-shaped body 1 from the joint 4. The top plate 10 is placed on the base formed by fixing the rod-shaped body 1, the support column 2, and the cross bar 3 to each other by the joint 4.

[0012] Next, the assembly structure of the assembly tool 100 will be described. In the following description, the assembly part indicated by the dotted line in FIG. 1 will be described as an example, but the basic structure is the same for other assembly parts. Figures 3 to 7 are diagrams for explaining the assembly structure of the embodiment.

[0013] The joint 4 has first support portions 4a1 and 4a2, second support portions 4b1 and 4b2, and third support portions 4c1 and 4c2. The first support portion 4a2 and the second support portion 4b1 are common members. When defining an X-axis parallel to the insertion direction of the rod-shaped body 1, the first support portions 4a1 and 4a2 have a pair of linear portions parallel to each other in the X-axis direction. When defining a Z-axis orthogonal to the X-axis, the second support portions 4b1 and 4b2 have a pair of linear portions formed parallel to each other on the ZX plane. When defining a Y-axis orthogonal to the X-axis and the Z-axis, the third support portions 4c1 and 4c2 are provided with a pair of U-shaped portions formed parallel to each other on the YZ plane.

[0014] And the end portions of the U-shaped portion of the third support portion 4c1 are respectively connected to the end portions of the first support portions 4a1 and 4a2, and the end portions of the U-shaped portion of the third support portion 4c2 are respectively connected to the end portions of the second support portions 4b1 and 4b2.

[0015] A concave portion 2a1 corresponding to the shape of the side portion of the rod-shaped body 1 is provided on the side surface 2a of the end portion of the support column 2. In the following description, the side surface 2a of the support column 2 is also referred to as the "surface 2a", and the side surface 2b opposite to the side surface 2a is also referred to as the "back surface 2b".

[0016] In addition, a fitting portion 2a2 into which the first support portion 4a1 fits is provided on the side surface 2a of the support column 2. Further, on the side surface 2b of the support column 2, a fitting portion 2b1 into which the first support portion 4a2 (the second support portion 4b1) fits and a fitting portion 2b2 into which the second support portion 4b1 fits are provided.

[0017] On the side surface 3a of the end of the horizontal bar 3, a concave portion 3a1 corresponding to the shape of the side portion of the rod-shaped body 1 is provided. Further, on the side portion 3a of the support column 3, a fitting portion 3a2 into which the second support portion 4b2 is fitted is provided. Further, on the side surface 3b of the horizontal bar 3, a fitting portion 3b1 into which the first support portion 4a1 is fitted and a fitting portion 3b2 into which the first support portion 4a2 (the second support portion 4b1) is fitted are provided. In the following description, the side surface 3a of the horizontal bar 3 is also referred to as the "front surface 3a" and the side surface 3b as the "back surface 3b". Although each of the above fitting portions can be omitted, providing the fitting portions can more firmly fix the rod-shaped body 1, the support column 2, and the horizontal bar 3 to each other.

[0018] As shown in FIG. 4, when the joint 4 engages with the support column 2 and the horizontal bar 3, an insertion port 5a (the portion indicated by the dotted line in the figure) into which the rod-shaped body 1 is inserted is formed by the concave portion 2a1 and the third support portion 4c1. An insertion port 5b into which the rod-shaped body 1 is inserted is formed by the concave portion 3a1 and the third support portion 4c2. The joint 4 supports the support column 2 and the horizontal bar 3 in a state where the support column 2 is orthogonal or substantially orthogonal to the horizontal bar 3 with the rod-shaped body 1 inserted into the insertion ports 5a and 5b.

[0019] As shown in FIGS. 5 to 7, when the rod-shaped body 1 is inserted into the insertion ports 5a and 5b, the first support portions 4a1 and 4a2 support the support column 2 from the front surface 2a side and the back surface 2b side of the support column 2 in a state where the rod-shaped body 1 is engaged with the concave portion 2a1 and the concave portion 3a1. Further, the first support portion 4a1 is fitted into the fitting portion 3b1 to support the horizontal bar 3 from the back surface 3b side of the horizontal bar 3.

[0020] The second support portion 4b1 is fitted into the fitting portion 3b2 of the horizontal bar 3, and the second support portion 4b2 is fitted into the fitting portion 3a2 of the horizontal bar 3 to support the horizontal bar 3 from the front surface 3a side and the back surface 3b side. Further, the second support portions 4b1 and 4b2 support the support column 2 from the back surface 2b side of the support column 2.

[0021] The third support portions 4c1 and 4c2 support one side surface 2c of the support column 2 and the side surface 3c on the side opposite to the surface of the horizontal bar 3 facing the support column 2. Thereby, the rod-shaped body 1, the support column 2, and the horizontal bar 3 are fixed by the joint 4.

[0022] By pulling out the rod-shaped body 1, the fixation between the rod-shaped body 1, the support column 2, and the cross bar 3 can be released, and the rod-shaped body 1, the support column 2, and the cross bar 3 can be separated individually. Returning to FIG. 2 for further explanation.

[0023] As shown in FIG. 2, in the assembly tool 100, the respective corner portions of the lower end portions (the ends closer to the ground) are coupled to each other with the structures shown in FIGS. 3 to 7. At the upper end portion 2d of each support column 2, a recess 2b3 is disposed on the back surface 2b side. Also in the structure of the upper end portion (the end on the side where the top plate 10 is placed), similar to the structure described in FIGS. 3 to 7, the joint 4 can be engaged with the support column 2 and the cross bar 3 to fix the rod-shaped body 1, the support column 2, and the cross bar 3.

[0024] By disposing the recess 2b3 on the back surface 2b side and fixing the rod-shaped body 1, the support column 2, and the cross bar 3 at the upper end portion, the support column 2 is disposed slightly obliquely with respect to the vertical line. Thereby, the force for clamping the rod-shaped body 1 by the insertion ports 5a, 5b is increased. Also, the forces for clamping the support column 2 and the cross bar 3 by the first support portions 4a1, 4a2, the second support portions 4b1, 4b2, and the third support portions 4c1, 4c2 are increased. Therefore, the rod-shaped body 1, the support column 2, and the cross bar 3 are more firmly fixed by the joint 4, and the strength when the assembly tool 100 is assembled can be increased.

[0025] As described above, the assembly tool 100 includes a rod-shaped body 1, a support column 2 having a concave portion 2a1 on its surface that corresponds to the shape of the side portion of the rod-shaped body 1 and is orthogonal or substantially orthogonal to the support column 2 when the rod-shaped body 1 is engaged, a cross bar 3 having a concave portion 3a1 on its surface that corresponds to the shape of the side portion of the rod-shaped body 1 and is orthogonal or substantially orthogonal to the cross bar 3 when the rod-shaped body 1 is engaged, insertion ports 5a and 5b that are formed by engaging with the support column 2 and the cross bar 3 and into which the rod-shaped body 1 is inserted, and a joint 4 that supports the support column 2 and the cross bar 3 in a state where the support column 2 is orthogonal or substantially orthogonal to the cross bar 3 with the rod-shaped body 1 inserted into the insertion ports 5a and 5b. Therefore, by inserting the rod-shaped body 1 into the insertion ports 5a and 5b, the rod-shaped body 1, the support column 2, and the cross bar 3 are fixed by the joint 4, and by pulling out the rod-shaped body 1 from the insertion ports 5a and 5b, the fixation between the support column 2 and the cross bar 3 can be easily released. Therefore, the assembly and disassembly of the assembly tool 100 can be easily performed.

[0026] In this embodiment, the rod-shaped body 1 has a cylindrical shape with rounded sides, but it is not limited to this and may be a prismatic shape. Also, in this embodiment, the shapes of the support column 2 and the cross bar 3 are chamfered, but they are not limited to those shown in the drawings. Further, each fitting portion of the support column 2 and the cross bar 3 can also be omitted. <Modification Example> FIG. 8 is a diagram for explaining the assembly tool of the modification example. Parts having the same structure are assigned the same reference numerals and the description thereof is omitted. The assembly tool 100a shown in FIG. 8 includes two rod-shaped bodies 1, eight short rod-shaped bodies 1a, four support columns 2, four cross bars 3a, and twelve joints 4.

[0027] In the assembly tool 100 described above, the assembly parts indicated by the dotted line in FIG. 1 were arranged in the order of the rod-shaped body 1, the support column 2, and the cross bar 3 from the front side of the paper. However, in the assembly tool 100, the assembly part indicated by the dotted line in FIG. 8 (that is, the part corresponding to the dotted line part of the assembly tool 100) is in the order of the rod-shaped body 1a, the cross bar 3, and the support column 2 from the front side. Even if the assembly method is changed in this way, the rod-shaped body 1a, the cross bar 3, and the support column 2 can be fixed by the joint 4.

[0028] Further, the horizontal bar 3a has a fitting portion in the central portion for fitting the joint 4. In the assembling tool 100a, the central portion of the horizontal bar 3a is fixed by the two rod-like bodies 1 and the joint 4. The assembling tool 100a has the strength as a base for simple use, and the above-described top plate 10 can also be placed on the upper portion. Further, by fixing the square and then fixing the central portion of the horizontal bar 3a with the two rod-like bodies 1 and the joint 4, the assembling tool 100a can be assembled relatively easily.

[0029] As described above, the assembling tool and the attaching tool of the present invention have been described based on the illustrated embodiments. However, the present invention is not limited thereto, and the configuration of each part can be replaced with any configuration having the same function. Further, any other arbitrary components or steps may be added to the present invention. Further, the present invention may be a combination of any two or more configurations (features) among the above-described embodiments.
