[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following, similar elements in all drawings will be designated by the same reference numerals, and duplicate explanations will be omitted. Furthermore, in the description below, previously described reference numerals will be used as necessary.

[0014] FIG. 1 shows a front view of a knockdown aquarium stand 1 according to one embodiment of the present invention, FIG. 2 shows a left side view of the knockdown aquarium stand 1, FIG. 3 shows a plan view of the knockdown aquarium stand 1, and FIG. 4 shows a bottom view of the knockdown aquarium stand 1. As shown in FIGS. 1 to 4, the knockdown aquarium stand 1 of the present invention is broadly composed of a lower frame 10 that is installed on the floor, a pair of opposing side frames 20, 30 that are fastened to the lower frame 10 with bolts, and an upper frame 40 that is located on the top of the knockdown aquarium stand 1 and is fastened to the side frames 20, 30 with bolts. Details of the lower frame 10, one of the side frames 20, and the upper frame 40 will be described individually below. Note that the pair of side frames 20, 30 have the same shape, so a detailed description of the other side frame 30 will be omitted.

[0015] <Lower Frame 10> A front view of the lower frame 10 that forms part of the knockdown aquarium stand 1 of the present invention is shown in Fig. 5, a left side view of the lower frame 10 is shown in Fig. 6, and a plan view of the lower frame 10 is shown in Fig. 7. As shown in Figs. 5 to 7, the lower frame 10 is broadly composed of one first lower frame member 11 and two second lower frame members 12, 13. In this embodiment, the second lower frame members 12, 13 are each shorter than the first lower frame member 11.

[0016] The two second lower frame members 12, 13 are arranged parallel to each other, as shown in Figure 7. The first lower frame member 11 is arranged in a direction perpendicular to the second lower frame members 12, 13, and both ends of the first lower frame member 11 are joined to each other near the centers of the two second lower frame members 12, 13. In other words, the one first lower frame member 11 and the two second lower frame members 12, 13 form an H-shape as a whole lower frame 10, as shown in Figure 7. The first lower frame member 11 and the second lower frame members 12, 13 will be described in detail below.

[0017] (First lower frame member 11) As shown in Figures 6 and 7, the first lower frame member 11 is a member located in the center of the lower frame 10, and both left and right ends of the first lower frame member 11 are connected to the two second lower frame members 12, 13 so that they intersect at right angles at approximately the center. The length direction of the first lower frame member 11 (the left-right direction in Figures 5 and 7) corresponds to the width direction (longitudinal direction) of the aquarium to be installed on the upper frame, which will be described later. Therefore, the length of the first lower frame member 11 can be freely adjusted depending on the width direction size (width dimension) of the aquarium to be installed.

[0018] (Second lower frame members 12, 13) 7, the second lower frame members 12, 13 are members arranged parallel to each other at both ends of the lower frame 10, and are joined at approximately the center of the second lower frame members 12, 13 so as to be perpendicular to both ends of the first lower frame member 11. The length direction of the second lower frame members 12, 13 (the left-right direction in FIG. 6) corresponds to the depth direction of the water tank to be placed on the upper frame, which will be described later.

[0019] Therefore, the length of the second lower frame members 12, 13 can be freely adjusted according to the depth dimension of the aquarium to be installed. In other words, by changing the dimensions of the first lower frame member 11 and the second lower frame members 12, 13 of the lower frame 10, it is possible to accommodate the installation of aquariums of different sizes (aquariums with different width and depth dimensions) without changing the height of the aquarium itself.

[0020] Furthermore, on the end faces on both sides of the second lower frame members 12, 13, as shown in Figures 5 to 7, a first plate P1 (P1a, P1b, P1c, P1d) is provided upright relative to the floor surface on which it is to be installed, and holes (through holes) H1, H2, H3, H4 are formed at positions away from the end faces of the second lower frame members 12, 13.

[0021] <Side frame 20> A front view of a pair of side frames and one of the side frames 20 is shown in Fig. 8, a left side view of the side frame 20 is shown in Fig. 9, and a plan view of the side frame 20 is shown in Fig. 10. The side frames 20 are components that form a pair of two to form part of the knockdown aquarium stand of the present invention as shown in Figs. 2 to 4. As shown in Fig. 8, the side frames 20 are formed from two opposing vertical frame members 21 and 22 extending vertically (up and down in the drawing), two opposing horizontal frame members 23 and 24 extending horizontally (left and right in the drawing), and four male threads 23A, 23B, 24A, and 24B extending inward.

[0022] The ends of these four vertical frame members 21, 22 and horizontal frame members 23, 24 are joined together, and the entire structure is formed into a rectangular (quadrilateral) shape, as shown in Fig. 8. Details of the vertical frame members 21, 22 and the horizontal frame members 23, 24 will be described below with reference to the drawings.

[0023] (Vertical frame members 21, 22) The vertical frame members 21, 22 are frame members that extend vertically as shown in Figures 8 to 10, and a pair of them are arranged facing each other to form the side frame 20. The horizontal frame members, which will be described later, are formed so that the entire side frame 20 becomes rectangular when their ends are joined together. In addition, brackets B1, B2 that protrude inward are provided on the upper ends of the vertical frame members 21, 22, as shown in Figures 9 and 10.

[0024] The brackets B1 and B2 serve to support the upper frame, which will be described later, as shown in Figures 8 to 10. Furthermore, the height of the installed tank is determined by the length of the vertical frame members, meaning that the tank height can be easily changed without changing the tank size by simply replacing the side frames with side frames of a different size.

[0025] 4, second plates P2 (P2a, P2b, P2c, P2d) that protrude inward can be provided on the lower end surfaces of the vertical frame members 21, 22. In this case, the second plates P2 (P2a, P2b) serve to place the ends of the second lower frame members of the lower frame 10 and to support the side frames and the lower frame together when assembling the knockdown aquarium stand.

[0026] (Horizontal frame members 23, 24) 8 to 10, the horizontal frame members 23, 24 are frame members that extend horizontally in the side frame 20, and a pair of them are installed facing each other to form the side frame 20. The above-mentioned vertical frame members are formed so that the entire side frame 20 becomes rectangular when their ends are joined together.

[0027] Furthermore, the horizontal frame members 23, 24 have four male threads 23A, 23B, 24A, 24B extending inward. Specifically, as shown in Figures 8 to 10, the horizontal frame member (first horizontal frame member) 23 located on the upper side has two male threads 23A, 23B for fastening to the upper frame, and the horizontal frame member (second horizontal frame member) 24 located on the lower side has two male threads 24A, 24B for fastening to the lower frame.

[0028] In this embodiment, as shown in Figures 8 to 10, four male thread portions 23A, 23B, 24A, 24B extending inward are formed on two horizontal frame members 23, 24. However, for example, two of the four male thread portions, 24A, 24B, may be formed on each of the vertical frame members 21, 22, and the remaining two male thread portions 23A, 23B may be formed on the first horizontal frame member 23 located above.

[0029] <Upper frame 40> A front view of the upper frame 40 is shown in Fig. 11, a left side view of the upper frame 40 is shown in Fig. 12, and a plan view of the upper frame 40 is shown in Fig. 13. Like the lower frame described above, the upper frame 40 is formed from a first upper frame member 41 and two second upper frame members 42, 43. In this embodiment, the second upper frame members 42, 43 are each shorter than the first upper frame member 41.

[0030] 13, the first upper frame member 41 is joined between two second upper frame members 42, 43 arranged in parallel, thereby forming an H-shape as a whole. Holes (long holes with one end open) H11, H12, H13, H14 are formed in the end faces of the second upper frame members 42, 43. The first upper frame member 41 and the second upper frame members 42, 43 will be described in detail below.

[0031] (First upper frame member 41) As shown in Figure 13, the first upper frame member 41 is a member located in the center of the upper frame 40, and both ends of the first upper frame member 41 are joined so as to intersect perpendicularly at approximately the center of the two second upper frame members 42, 43. The length direction of the first upper frame member 41 (the left-right direction in Figure 13) corresponds to the width direction of the aquarium to be installed. Therefore, the length of the first upper frame member 41 can be freely adjusted according to the width size (width dimension) of the aquarium to be installed.

[0032] (Second upper frame members 42, 43) The second upper frame members 42, 43 are members arranged parallel to each other on the left and right sides of the upper frame 40 as shown in Figure 13, and are joined at approximately the center of the second upper frame members 42, 43 so as to be perpendicular to both ends of the first upper frame member 41. The length direction of the second upper frame members 42, 43 (the left-right direction in Figure 12) corresponds to the depth direction of the aquarium in which they will be installed.

[0033] Therefore, the length of the second upper frame members 42, 43 can be freely adjusted depending on the depth dimension of the aquarium to be installed. In other words, by changing the second upper frame members to upper frames with different dimensions, it is possible to accommodate installation of aquariums of different sizes (aquariums with different width and depth dimensions) without changing the height of the aquarium itself.

[0034] 11 to 13, third plates P3 (P3a, P3b, P3c, and P3d) are provided upright on both end surfaces of the second upper frame members 42 and 43, and holes (long holes with an open bottom) H11, H12, H13, and H14 are formed at positions away from the end surfaces of the second upper frame members 42 and 43. By forming the holes H11, H12, H13, and H14 as long holes with an open bottom as shown in FIG. 11, the holes in the third plates can be easily fitted into male threads formed in the side frames. The holes H11, H12, H13, and H14 formed in the third plates P3 (P3a, P3b, P3c, and P3d) of this embodiment may be through-holes instead of long holes as shown in FIG. 11.

[0035] Next, the assembly process for the knockdown aquarium stand 1 shown in Figures 1 to 4 will be described with reference to the drawings. This assembly process can be broadly divided into a first assembly process in which a pair of side frames are installed, a second assembly process in which the lower frame is assembled to the side frames, and a third assembly process in which the upper frame is assembled to the side frames. Figure 14 shows an exploded perspective view of the fastening portion between the lower frame 10 and the side frames 20 in the second assembly process, and Figure 15 shows an exploded perspective view of the fastening portion between the upper frame 40 and the side frames 20 in the third assembly process. Details of the first to third assembly processes will be described below with reference to the drawings.

[0036] (First assembly process: Installation of side frames) First, a pair of side frames are placed facing each other on the floor in an upright position, with the four male threads on each side frame facing inward, the brackets in the upper position, and the second plate in the lower position. At this time, the distance between the side frames is set in advance so that the lower frame can be placed on the second plate in the next step, the second assembly step.

[0037] (Second assembly process: Installing and assembling the lower frame) After the pair of side frames are installed in the first assembly process, the end of the second lower frame member 12 of the lower frame 10 is placed on the second plate P2a (P2) provided at the end of the vertical frame member 21 of the side frame 20 as shown in Fig. 14, and at the same time, the male thread portion 24A provided on the horizontal frame member 24 of the side frame 20 is inserted in the direction of the arrow shown in Fig. 14 into the hole portion (through hole) H1 of the first plate P1a (P1) provided on the end face of the second lower frame member 12. At this time, because the end of the second lower frame member 12 is placed on the second plate P2a (P2), the positioning of the male thread portion 24A and the hole portion (through hole) H1 of the first plate P1a (P1) can be easily performed.

[0038] After the male threads 24A shown in Fig. 14 are fully inserted into the holes (through holes) H1, the side frames and the lower frames are fastened together with nuts (not shown) at a predetermined tightening torque. Therefore, the side frames can be made to stand on their own simply by inserting the two male threads of the side frames into the holes (through holes) of the first plate attached to the lower frame, so the fastening work of the lower frame and side frames can be done without an assistant.

[0039] (3rd assembly process: Installing and assembling the upper frame) In the second assembly process, after assembling the lower frame to the pair of side frames, as shown in Figure 15, the male thread portion 23A provided on the horizontal frame 23 of the side frame 20 is fitted in the direction of the arrow from above into the hole portion (long hole) H11 provided in the third plate P3a (P3) at the end of the second upper frame member 42 of the upper frame 40, and at the same time, the end of the second frame member 42 of the upper frame 40 is placed on the bracket portion B1 of the vertical frame member 21.

[0040] After the male threads 23A are completely fitted into the holes (slots) 11, the side frames and the upper frame are fastened together with a predetermined tightening torque using nuts (not shown). That is, by making the holes H11 in the third plate P3a (P3) elongated as shown in Figure 11, the upper frame can be easily assembled to the side frames by simply lowering it from above the four male threads of the side frames and inserting it into the elongated holes. In other words, the assembly work of the knockdown aquarium stand can be completed individually and simply. [Explanation of symbols]
