The multi-stage locker according to this embodiment will be described below.

[0018] 1(a) to 1(d) and 2(a) and 2(b), the multi-tiered locker 500 of this embodiment has a lower locker 1a and an upper locker 1b (sometimes referred to as locker 1), and these lockers 1a and 1b are stacked one on top of the other to form a multi-tiered structure. Side fixtures 501a, 501b, 501c, and 501d (sometimes referred to as side fixtures 501) are provided to secure these lockers 1a and 1b.

[0019] As shown in Figures 3(a) to 3(d) and 4(a) and 4(b), the locker 1 according to this embodiment comprises a top panel 2, a bottom panel 3, a right side panel 4, a door panel 5, a back panel 6, and a left side panel 7. Each panel is approximately rectangular, and these panels are connected and fixed together to form the locker 1, which is approximately a rectangular parallelepiped.

[0020] Here, "approximately rectangular" means not only a perfect rectangle, but also one that has been modified as long as it can still perform the function of locker 1, such as one with a curved portion, and the same applies to "approximately rectangular prism."

[0021] The top panel 2 and the bottom panel 3 are arranged in a direction (with the main surfaces horizontal) that forms the horizontal plane of the storage area of ​​the locker 1. The top panel 2 and the bottom panel 3 are arranged opposite to each other.

[0022] The right side panel 4, left side panel 7, door panel 5, and back panel 6 are arranged in a direction that defines the vertical plane of the storage area of ​​the locker 1 (with the main surfaces vertical). The right side panel 4 and the left side panel 7 are arranged opposite each other. The door panel 5 and back panel 6 are arranged opposite each other.

[0023] Each edge of the rear panel 6 can be connected and fixed to one edge of the bottom panel 3, top panel 2, right side panel 4, and left side panel 7. Furthermore, the rear panel 6 can be connected and fixed at the edges where the bottom panel 3 and the left side panel 7, the left side panel 7 and the top panel 2, the top panel 2 and the right side panel 4, and the right side panel 4 and the bottom panel 3 come into contact.

[0024] The door panel 5 is rotatably connected at one of its top, bottom, left, or right sides to the top panel 2, bottom panel 3, right side panel 4, or left side panel 7, and is installed so as to be able to open and close around this connecting part as a rotation axis. In the case of this embodiment, the door panel 5 is rotatably connected around the connecting part with the right side panel 4 as a rotation axis.

[0025] As shown in FIGS. 1(a) to 1(d), 2(a) and 2(b), and 4(a) and 4(b), a base panel 8 may be provided below the lowest locker 1.

[0026] In a multi-tiered locker 500 in which the lockers 1 of this embodiment are stacked in two tiers, for example, four side fixing devices 501a, 501b, 501c, and 501d are used, as shown in Figures 1(a) to (d) and Figures 2(a) and (b).

[0027] Side fastener 501a straddles the side of the bottom panel 3 of lower locker 1a and fastens the right side panel 4 of lower locker 1a to the right side of base panel 8. Side fastener 501b straddles the side of the bottom panel 3 of lower locker 1a and fastens the left side panel 7 of lower locker 1a to the left side of base panel 8. Side fastener 501c straddles the side of the bottom panel 3 of upper locker 1b and the side of the top panel 2 of lower locker 1a and fastens the right side panel 4 of upper locker 1b to the right side panel 4 of lower locker 1a. Side fastener 501d straddles the side of the bottom panel 3 of upper locker 1b and the side of the top panel 2 of lower locker 1a and fastens the left side panel 7 of upper locker 1b to the left side panel 7 of lower locker 1a.

[0028] Side fasteners 501a, 501b, 501c, and 501d can have different shapes, but in this embodiment, they are all formed with the same shape. In other words, side fasteners 501c and 501d have a length that allows them to fasten, via bottom panel 3 and top panel 2, connecting holes 4f and 7f provided at the bottom of right side panel 4 and left side panel 7 of upper locker 1b to connecting holes 4f and 7f provided at the top of right side panel 4 and left side panel 7 of lower locker 1a. Because side fasteners 501a and 501b have the same length as side fasteners 501c and 501d, connecting hole 8c of base panel 8 is provided below (on the bottom side of) the side of base panel 8.

[0029] As shown in FIGS. 1(c) and 1(d), the side fasteners 501a, 501b, 501c, and 501d protrude from the side surfaces of the right side panel 4, left side panel 7, and base panel 8 by the thickness of each panel. However, it is also possible to form recesses in the side surfaces of the right side panel 4, left side panel 7, base panel 8, bottom panel 3, and top panel 2, and fit the side fasteners 501a, 501b, 501c, and 501d into these recesses. In this case, the surfaces of the side fasteners 501a, 501b, 501c, and 501d do not protrude from the side surfaces of the right side panel 4, left side panel 7, and base panel 8, but are flat and coincident with these side surfaces. This allows the surface of the multi-tiered locker 500 to be flat, improving storage capacity and aesthetics.

[0030] The position, shape, number, etc. of the side fixing members 501a, 501b, 501c, and 501d can be changed in various ways.

[0048] A plurality of through holes 6b are provided in the rear panel 6. By forming through holes 6b in the rear panel 6, the amount of panel material used can be reduced, leading to reduced manufacturing costs. In addition, breathability inside the locker 1 is ensured, allowing for long-term storage of clothing and other items.

[0049] A plurality of connecting holes 6c (two in this embodiment) are provided in the center of the rear panel 6. When connecting a plurality of lockers 1, the connecting holes 6c can be used to fasten adjacent lockers 1 on the rear side by inserting a connecting tool (not shown) into the connecting holes 6c. Note that in this embodiment, it is also possible to eliminate the connecting holes 6c. In this case, adjacent lockers 1 on the rear side can be fastened by inserting a connecting tool (not shown) into the through-hole 6b.

[0050] [2-4] Door panel Figures 8(a) to 8(f) show an outer view, an inner view, and a partially enlarged view of a door panel of a locker according to one embodiment of the present invention. Figure 9 shows a partially enlarged view of a door panel of a locker according to one embodiment of the present invention. The door panel of a locker according to this embodiment will be described below.

[0051] As shown in FIGS. 8(a) and (b), the door panel 5 includes a handle portion 5a, support shafts 5b and 5c, and a through-hole 5d. The handle portion 5a is disposed near the left side (the side of the left side panel 7) of the door panel 5. However, the position and shape of the handle portion 5a can be changed in various ways.

[0052] The support shafts 5b and 5c are provided so as to protrude from the upper and lower side surfaces of the door panel 5. The support shafts 5b and 5c are each axially symmetrical (cylindrical), aligned in a straight line, and form the rotation axis of the door panel 5. The support shafts 5b and 5c are not integrally molded with the door panel 5 but are formed as separate parts. As shown in Figures 8(c) to 8(f), the support shafts 5b and 5c are detachably fitted into the support shaft grooves 5b' and 5c'. Here, Figure 8(e) shows the state in which the support shaft 5b is fitted into the support shaft groove 5b', and Figure 8(f) shows the state in which the support shaft 5b is removed from the support shaft groove 5b'. The support shaft grooves 5b' and 5c' are open, and the support shafts 5b and 5c can be pushed out through these openings to facilitate the attachment and detachment of the support shafts 5b and 5c.

[0053] If the support shafts 5b, 5c are formed integrally with the door panel 5, etc., a large force is applied to the support shafts 5b, 5c when attaching or detaching the door panel 5, making them prone to damage and requiring replacement of the entire panel. In contrast, in this embodiment, the support shafts 5b, 5c are configured to be detachable from the support shaft grooves 5b', 5c', so that even if the support shafts 5b, 5c are damaged, it is possible to avoid having to replace the entire panel.

[0054] 9, the shafts 5b and 5c are fitted into the shaft holes 3c and 2c of the bottom panel 3 and the top panel 2, respectively, so that the door panel 5 is rotatably connected to the bottom panel 3 and the top panel 2 around the shafts 5b and 5c as the rotation axis. Therefore, a user can hold the handle 5a and open or close the door panel 5 around the shafts 5b and 5c of the door panel 5 as the rotation axis.

[0055] A plurality of through holes 5d are provided in the lower right portion of the surface of the door panel 5. By forming the through holes 5d in the door panel 5, the amount of panel material used can be reduced, thereby reducing manufacturing costs. Furthermore, the ventilation inside the locker 1 is ensured, allowing for the long-term storage of clothing and other items. Furthermore, the multiple through holes 5d contribute to the design of the locker 1; for example, by forming a cherry blossom petal pattern as in this embodiment, the design can be improved. Furthermore, by changing the formation pattern of the through holes 5d depending on the contents stored inside the locker 1, the contents can be identified without opening the door panel 5.

[0056] The door panel 5 may be equipped with a locking mechanism as needed. In addition, to improve ventilation inside the locker 1, through holes may be provided in panels other than the door panel 5 and the back panel 6 as needed.

[0057] [2-5] Base panel 10(a) and 10(b) show a top view, a side view, and a bottom view of a base panel of a locker according to one embodiment of the present invention. Here, in the base panel of FIG. 10(a), the side view above the top view is a side view of the back side of the base panel, the side view below the top view is a side view of the front side of the base panel, and the side view to the right of the top view is a side view of the right side of the base panel. The base panel of the locker according to this embodiment will now be described.

[0058] As shown in FIGS. 10(a) and 10(b), the base panel 8 has a groove 8a, connecting holes 8b and 8c, an adjuster mounting portion 8d, and a fixing hole 8e.

[0059] The grooves 8a are provided at the left, right and rear edges of the top surface of the base panel 8. Joint members (not shown) for fixing the base panel 8 to the locker 1 placed above may be fitted into the grooves 8a of the base panel 8.

[0060] When connecting multiple lockers 1, connecting holes 8b and 8c can be used to fasten adjacent lockers 1 by inserting connecting devices (not shown) into connecting holes 8b and 8c. Here, for example, connecting hole 8b may be used to fasten base panels 8 that are connected to the left and right or back, and connecting hole 8c may be used to fasten lockers 1 installed above with side fasteners 501.

[0061] The adjuster attachment portions 8d are provided at the four corners of the bottom surface of the base panel 8, and allow an adjuster (not shown) to be attached.

[0062] The fixing hole 8e is provided in the center near the front of the base panel 8. A base fixing device (not shown) is fitted into the fixing hole 8e. In this embodiment, the base fixing device is fitted into the installation surface on which the locker 1 is installed and the fixing hole 8e, so that the locker 1 can be firmly fixed to the installation surface, thereby improving the effect of preventing the locker 1 from tipping over.

[0063] In this embodiment, for example, when locker 1 is used as a display shelf, door panel 5 can be omitted. Also, when locker 1 is placed against the wall of a building, the wall can be used as back panel 6, and back panel 6 can be omitted. Therefore, depending on the application and usage situation, locker 1 may be composed of top panel 2, bottom panel 3, right side panel 4, and left side panel 7.

[0064] [2-6] Panel materials The materials used for each panel (top panel 2, bottom panel 3, right side panel 4, door panel 5, back panel 6, left side panel 7 and base panel 8) that make up the locker 1 of this embodiment can be metals such as steel, aluminum, copper, etc., but it is preferable to use synthetic resins such as ABS resin and PH resin.

[0065] This makes the locker lightweight and durable, reduces the burden of assembly work, and makes disposal easier. Furthermore, because such plastic lockers 1 do not rust, they are suitable for use near water sources such as swimming pools, water factories, schools, and public baths. It is preferable to use environmentally friendly plastic panels, such as plastic made from 100% recycled resources, recyclable plastic, or biodegradable plastic.

[0066] [3] Connection structure In the locker 1 of this embodiment, a plurality of lockers 1 can be stacked vertically, or a plurality of lockers 1 can be lined up horizontally or back to back.

[0067] As shown in Figures 11(a) to 11(d), a two-row, two-tier locker is also possible. This example is a structure in which an additional row is added to the multi-tier locker of Figure 1. In this case, the lower lockers 1a1 and 1a2 are connected by fitting a connector into the connecting hole 4e in the right side panel 4 of locker 1a1 and the connecting hole 7e in the left side panel 7 of locker 1a2. The upper lockers 1b1 and 1b2 are connected by fitting a connector into the connecting hole 4e in the right side panel 4 of locker 1b1 and the connecting hole 7e in the left side panel 7 of locker 1b2.

[0068] Then, a top fixture 510 may be fitted into the connecting hole 2d of the top panel 2 of the upper locker 1b1 and the connecting hole 2d of the top panel 2 of the upper locker 1b2 to connect the top panel 2 of the upper locker 1b1 and the top panel 2 of the upper locker 1b2.

[0069] The top fixture 510 has two protrusions on the underside, which fit into the connecting holes 2d. From the perspective of improving the design, the top fixture 510 may have a leaf pattern drawn on it, as shown in the drawing.

[0070] As shown in Figures 12(a) to (d), two rows and two columns of lockers may be added to the rear of the structure of Figure 11. In this case, the lower lockers 1a3 and 1a4 are connected by fitting a connector into the connecting hole 4e in the right side panel 4 of locker 1a3 and the connecting hole 7e in the left side panel 7 of locker 1a4. The upper lockers 1b3 and 1b4 are connected by fitting a connector into the connecting hole 4e in the right side panel 4 of locker 1b3 and the connecting hole 7e in the left side panel 7 of locker 1b4.

[0071] Furthermore, in the lower lockers 1a1 to 1a4, lockers 1a1 and 1a4 are connected by fitting a connector into connecting hole 6c in back panel 6 of locker 1a1 and connecting hole 6c in back panel 6 of locker 1a4, and lockers 1a2 and 1a3 are connected by fitting a connector into connecting hole 6c in back panel 6 of locker 1a2 and connecting hole 6c in back panel 6 of locker 1a3. In the upper lockers 1b1 to 1b4, lockers 1b1 and 1b4 are connected by fitting a connector into connecting hole 6c in back panel 6 of locker 1b1 and connecting hole 6c in back panel 6 of locker 1b4, and lockers 1b2 and 1b3 are connected by fitting a connector into connecting hole 6c in back panel 6 of locker 1b2 and connecting hole 6c in back panel 6 of locker 1b3.

[0072] Then, top fixing devices 510 are fitted into connecting holes 2d in the top panel 2 of upper locker 1b1 and connecting holes 2d in the top panel 2 of upper locker 1b2, top fixing devices 510 are fitted into connecting holes 2d in the top panel 2 of upper locker 1b1 and connecting holes 2d in the top panel 2 of upper locker 1b3, top fixing devices 510 are fitted into connecting holes 2d in the top panel 2 of upper locker 1b2 and connecting holes 2d in the top panel 2 of upper locker 1b4, and top fixing devices 510 are fitted into connecting holes 2d in the top panel 2 of upper locker 1b3 and connecting holes 2d in the top panel 2 of upper locker 1b4. Furthermore, top fixing devices 520 are fitted into the four adjacent central connecting holes 2d in the top panel 2 of each of upper lockers 1b1, 1b2, 1b3, and 1b4.

[0073] Top fixture 520 has four protrusions on the underside, which fit into connecting holes 2d. From the perspective of improving design, top fixture 520 may have a leaf pattern drawn on it, as shown in the drawing.

[0074] As shown in Figures 11(b) to (d) and 12(b) to (d), the top fixing devices 510, 520 protrude from the surface of the top panel 2 by the thickness of the device. However, it is also possible to form a recess in the surface of the top panel 2 and fit the top fixing devices 510, 520 into this recess. In this case, the surfaces of the top fixing devices 510, 520 will not protrude from the surface of the top panel 2, but will be flat and flush with the surface of the top panel 2. This allows the surface of the multi-stage locker 500 to be flat, improving storage capacity and aesthetics.

[0075] [4] Assembled The locker 1 of this embodiment can be easily assembled and disassembled without using tools such as a screwdriver.

[0076] [4-1] Assembly structure Figure 13 shows an exploded perspective view of a locker according to one embodiment of the present invention. The assembly structure of the locker according to this embodiment will be described below. For the sake of convenience, the left side panel 7 is omitted from Figure 13, but it has the same structure as the right side panel 4.

[0077] 13, the rear panel 6 is in contact with the top panel 2, the bottom panel 3, and the right side panel 4 at its four side surfaces. Protrusions 6a (fitting portions) formed on the four side surfaces of the rear panel 6 fit into grooves 2a (fitted portions) (not shown) of the top panel 2, grooves 3b (fitted portions) of the bottom panel 3, and grooves 4a (fitted portions) of the right side panel 4, respectively. In this way, the rear panel 6 is connected to the top panel 2, bottom panel 3, and right side panel 4.

[0078] The support shaft 5b on the upper side surface of the door panel 5 and the support shaft 5c on the lower side surface of the door panel 5 are fitted into the shaft hole 2c of the top panel 2 and the shaft hole 3c of the bottom panel 3, respectively. As a result, the door panel 5 is rotatably connected to the top panel 2 and the bottom panel 3, with the support shafts 5b and 5c as rotation axes.

[0079] When stacked vertically, a base panel 8 may be provided below the bottom panel 3 of the lowest layer.

[0080] The frame 40 (first frame) of the right side panel 4 has a protrusion 4b (fitting portion) on the upper side surface and a protrusion 4c (fitting portion) (not shown) on the lower side surface.

[0081] The top panel 2 and the bottom panel 3 have groove portions 2b (engaged portions) and groove portions 3b (engaged portions) (not shown) on their lower and upper sides (i.e., the sides that contact the right side panel 4), respectively, that engage with the protrusion portions 4b and 4c. The protrusions 4b and 4c of the right side panel 4 fit into the grooves 2b and 3b of the top and bottom panels 2 and 3, respectively, and the right side panel 4 is fixed to the top and bottom panels 2 and 3.

[0082] Furthermore, to ensure that the frame 40 of the right side panel 4 is securely fixed to the bottom panel 3 (and top panel 2) and prevent them from separating, it can be connected and fixed using a connecting device 100, which will be described later, for example, in the connecting area 9 circled in Figure 13. The right side panel 4 has openings 4d (guide openings) on the upper and lower side surfaces for installing the connector 100. For ease of visibility, one connecting area 9 is shown circled in Figure 13, but other areas having openings 4d also serve as connecting areas 9 for installing the main connector 10, and the same is true for the left side panel 7.

[0083] The right side panel 4 is provided with a frame 47 (second frame) arranged along a direction (Z direction in the drawing) intersecting the direction (X direction in the drawing) in which the frame 40 (first frame) extends. The frame 47 is provided with a support portion 41 (lever support portion) that supports the connector 100. The frame 47 may be configured as a rib.

[0084] The following description will be given taking as an example a mechanism for fastening the right side panel 4 to the bottom panel 3, but the same applies to connecting and fastening the right side panel 4 to the top panel 2. That is, connector 100 is used to fasten a first panel to a second panel. Furthermore, a similar fastening mechanism may also be used to fasten the back panel 6 to the bottom panel 3, the left side panel 7 to the bottom panel 3, the back panel 6 to the left side panel 7, etc.

[0085] [4-2] Example of connector 1 Figures 14(a) and (b) are diagrams illustrating the configuration of the main coupler 10 (slide lever) and the auxiliary coupler 20 (coupler plate) that make up the coupler 100 of Example 1. Figure 14(a) is a perspective view showing the main coupler 10 and the auxiliary coupler 20, and Figure 14(b) is a perspective view of the main coupler 10 and the auxiliary coupler 20 combined together.

[0086] As shown in Figure 14(a), the connector 100 includes a main connector 10 (slide lever) and an auxiliary connector 20 (connection plate). The main connector 10 includes a hook 11, a support shaft 12, and a pressing portion 13 (wing). The hook 11 and the pressing portion 13 are fixed to the support 12. The pressing portion 13 protrudes from the support 12 and can be configured as a plate extending, for example, symmetrically in the radial direction of the support 12.

[0087] The support part 12 has an operating part 14 (finger hook part) at its end. In the process of assembling the locker 1, an operator can operate the operating part 14 of the main connector 10 with his or her fingers. The hook portion 11 is located at the end of the support portion 12 facing the operating portion 14. The pressing portion 13 is located between the hook portion 11 and the operating portion 14. The support portion 12 has a connecting portion 16 that connects the hook portion 11 and the pressing portion 13, and the connecting portion 16 is configured in a cylindrical shape.

[0088] The hook 11 has a first abutment portion 151 and a second abutment portion 152. The first abutment portion 151 and the second abutment portion 152 have a first abutment surface S151 and a second abutment surface S152 that are parallel to each other. The second abutment portion 152 of the hook 11 may have an inclined portion 153.

[0089] The connecting aid 20 has an opening 21 (insertion portion), and a support post receiving portion 22 that receives the support post 12 is provided in the center of the opening 21. The opening 21 is configured so that the pressing portion 13 and the operating portion 14 of the main coupler 10 can be inserted therethrough. The cross-sectional shape of the support post receiving portion 22 forms, for example, a part of a circle in which the connecting portion 16 can be inscribed, and rotatably supports the support post 12 (particularly the connecting portion 16) of the main coupler 10. Furthermore, the support post receiving portion 22 fixes the position of the support post 12 within the opening 21, and when the main coupler 10 slides, the connecting aid 20 can also slide.

[0090] Pressed portions 23 (wing supports) are provided in the center of connecting aid 20. Pressed portions 23 are provided on the left and right sides of the center of opening 21 so that pressing portion 13 comes into contact with them. The connecting aid 20 has a thick central pressed portion 23 and is provided with an inclined portion 24 (slider) connected to the pressed portion 23 so that both sides are thinner. The cross-sectional shape of the connecting aid 20 is configured to be, for example, triangular or trapezoidal. The pressed portion 23 receives the pressing portion 13 of the main connecting device 10.

[0091] As shown in Figure 14(b), in the connection region 9, the pressing portion 13 of the main connector 10 is inserted through the opening 4d of the frame 40 and the opening 21 of the connection aid 20 so that the frame 40 of the right side panel 4 is sandwiched between the connection aid 20 and the first abutment portion 151 of the main connector 10. Although the opening 4d of the frame 40 is not shown in FIG. 14(b), the opening 4d of the frame 40 is located below the opening 21 of the connecting aid 20. The bottom surface 26 of the main connector 10 and the first contact surface S151 of the hook portion 11 come into contact with both sides of the frame 40 of the right side panel 4. In this state, the first contact surface S151 and the second contact surface S152 of the hook portion 11 of the main coupler 10 are arranged opposite to the bottom surface 26 of the connecting aid 20.

[0092] Note that protrusions 25 may be provided on pressed portion 23. Protrusions 25 can be configured to protrude from the surface of pressed portion 23. As will be described later, by rotating main coupler 10 by 90 degrees, protrusions 25 can locally press pressing portion 13 of main coupler 10, thereby strengthening the connection between auxiliary connection device 20 and main coupler 10.

[0093] Figure 15(a) is an oblique view showing the relationship between the main coupler 10 and the connecting aid 20 and the frame 40, Figure 15(b) is a side view showing the relationship between the main coupler 10 and the connecting aid 20 and the frame 40, and Figures 15(c) and (d) are top views and partially enlarged views of the connecting aid 20 and the main coupler 10. 15(a) and 15(b), the connecting assisting device 20 and the main connecting device 10 are rotated relative to each other by 90 degrees. As a result, the pressed portion 23 receives the pressing portion 13. The support 12 forms a rotation axis for rotating the pressing portion 13 and the hook portion 11, and the support receiving portion 22 forms a rotation bearing, so that the main connecting device 10 can rotate relative to the connecting aid 20.

[0094] The pressing portion 13 is guided so as to slide on the inclined portion 24 and moves to the pressed portion 23. Therefore, the inclined portion 24 is provided in a region that includes the rotation (turning) range of the pressing portion 13 (so as to encompass the rotation range). Specifically, the inclined portion 24 is formed at least from the center of the connecting aid 20 over the entire length D of the pressing portion 13 (the length in the longitudinal direction of the pressing portion 13), and is provided so as to be able to come into contact with the pressing portion 13 (see FIGS. 15(b) and (c)). Because the thickness of the pressed portion 23 of the connecting aid 20 is large, as the pressing portion 13 moves along the inclined portion 24, the pressure gradually increases in the direction of the arrow in Figure 15(b), pressing the connecting aid 20 against the first abutment portion 151 of the hook portion 11. The pressing force of the connecting auxiliary tool 20 and the first abutting portion 151 against the frame 40 of the right side panel 4 increases, and the frame 40, the main connecting tool 10, and the connecting auxiliary tool 20 are firmly fixed. Since the configuration is such that the pressing force of the pressing portion 13 against the connecting auxiliary tool 20 is gradually increased by using the inclined portion 24, the assembly work becomes easy.

[0095] As shown in FIG. 15(c), the length L1 in the long side direction of the opening 21 is longer than the total length D of the pressing portion 13, and the length L2 in the short side direction of the opening 21 is longer than the width W of the pressing portion 13. Therefore, as shown in FIG. 14(b), the pressing portion 13 passes through the opening 21. However, since the length L2 in the short side direction of the opening 21 is shorter than the total length D of the pressing portion 13, as shown in FIG. 15(a), by rotating the main connecting tool 10 by 90 degrees, the pressing portion 13 does not come out of the opening 21. In addition, it is set so that W < D.

[0096] Also, as shown in FIG. 14(b), from the state where the pressing portion 13 is located on the opening 21, as shown in FIG. 15(a), in order for the pressing portion 13 to rotate and ride on the pressed portion 23, the edge portion 210 surrounding the opening 21 may be formed in a tapered shape to guide the rotation of the pressing portion 13. For example, the edge portion 210 may be provided with an inclination such that the thickness decreases as it approaches the opening 21.

[0097] Further, an engaging portion 27 (engaging portion for arrangement) may be provided on the bottom surface 26 of the connecting auxiliary tool 20, and a first engaged portion 431 (first engaged portion for arrangement) and / or a second engaged portion 432 (second engaged portion for arrangement) that engages with the engaging portion 27 may be provided on the frame 40. In addition, the first engaged portion 431 and the second engaged portion 432 may be simply referred to as an engaged portion 430 (engaged portion for arrangement). FIG. 15(d) is an enlarged view of the region surrounded by the dotted circle in FIG. 15(b). For example, the engaging portion 27 may be configured as a convex portion protruding from the bottom surface 26, and the engaged portion 430 may be configured as a concave portion (or groove) recessed from the surface of the frame 40, but it is not limited thereto.

[0098] The engaging portion 27 and the engaged portion 430 engage with each other to determine the position (arrangement) of the main connector 10 and the auxiliary connector 20 on the frame 40, or the engaging portion 27 and the engaged portion 430 can function as anti-slip devices. By providing two types of engaged portions 430, a first engaged portion 431 and a second engaged portion 432, different positions of the main connector 10 and the auxiliary connector 20 on the frame 40 can be determined. 15(b), the engaging portion 27 of the connection aid 20 is shown in a state where it is disposed at a first position where it is engaged with the first engaged portion 431. When the main coupler 10 and the connection aid 20 move to the right (X direction) in the figure, the engaging portion 27 of the connection aid 20 engages with the second engaged portion 432 and is disposed at a second position. The main coupler 10 and the auxiliary coupling device 20 can be selectively moved to and positioned at the first position or the second position by cooperation between the engaging portion 27 and the first and second engaged portions 431 and 432. This function is particularly effective when the pressing force from the pressing portion 13 is applied to the auxiliary coupling device 20.

[0099] Figures 16(a) and (b) are perspective views showing the relationship between the right side panel 4, the bottom panel 3, the main connector 10 and the connecting aid 20, Figure 16(c) is a side view showing the relationship between the right side panel 4, the bottom panel 3, the main connector 10 and the connecting aid 20, and Figure 16(d) is a plan view of the support part 41 that supports the main connector 10.

[0100] 16(a), the right side panel 4, to which the main connector 10 and the auxiliary connector 20 are fixed to the frame 40, is fitted into the bottom panel 3. The protrusion 4c of the right side panel 4 fits into the groove 3b of the bottom panel 3. The frame 40 may be provided with an auxiliary wall 42. The auxiliary wall 42 can determine the position of the connection aid 20 when the main connector 10 and the connection aid 20 are rotated 90 degrees when the main connector 10 and the connection aid 20 are in the first position, and also functions as a guide for attaching the main connector 10 and the connection aid 20 to the frame 40. The right side panel 4 may be provided with a slide guide 31 (sliding guide portion) that supports the bottom surface of the hook portion 11 of the main connector 10 and guides the sliding movement of the main connector 10.

[0101] The state shown in Figure 16(a) shows the state before the right side panel 4 and bottom panel 3 are fastened together by the main coupler 10 and the connection aid 20. The main coupler 10 and the connection aid 20 are positioned in a first position where the engaging portion 27 (see Figure 15(b)) engages with the first engaged portion 431. The first position corresponds to the preparation position before fastening.

[0102] A frame 47 (second frame) is disposed along a direction intersecting (or perpendicular to) the frame 40 and is provided with a support portion 41. 16(b), by sliding the main coupler 10 and the auxiliary connection device 20 in the X direction (the direction of the white arrow) in the figure, the support portion 12 of the main coupler 10 (particularly the side surface of the support portion 12) comes into contact with the support portion 41. The support portion 41 supports the coupler 100, particularly the side surface of the support portion 12, and can determine the position of the main coupler 10 along the longitudinal direction of the frame 40. The support 12 of the main connector 10 is slidable in the X direction (longitudinal direction of the frame) in the drawing within the range of the opening 4d of the frame 40. The opening 4d can guide the movement of the support 12.

[0103] In the state shown in Figure 16(b), the main coupler 10 and the connecting aid 20 are positioned in the second position where the engaging portion 27 (see Figure 15(b)) engages with the second engaged portion 432. This state indicates that the right side panel 4 and the bottom panel 3 are fixed together. The second position corresponds to the fixed connecting position.

[0104] The bottom panel 3 is provided with a hook receiving portion 35 (hook receiving portion) for connection. The inclination angle of the inclined portion 153 is set so that when the tip E35 of the hook receiving portion 35 abuts against the inclined portion 153 of the second abutment portion 152 and moves toward the support portion 41 of the main connector 10, the hook receiving portion 35 is pressed toward the frame 40.

[0105] 16(b), the tip E35 of the hook receiving portion 35 is configured to contact the side surface of the first abutment portion 151 of the hook portion 11, and the position of the hook portion 11 is determined by the hook receiving portion 35 and the side surface of the first abutment portion 151, but this is not limitative. Since the relative positions can be determined by the strut portion 12 and the support portion 41, the hook receiving portion 35 and the side surface of the first abutment portion 151 may be spaced apart.

[0106] The second contact portion 152 presses (pushes up) the hook receiving portion 35 of the bottom panel 3 toward the frame 40. Meanwhile, the protrusion 4c of the right side panel 4 presses (pushes down) the groove portion 3b of the bottom panel 3. As a result, the right side panel 4 and the bottom panel 3 are connected and fixed together via the main connector 10 and the auxiliary connector 20. The protrusion 4c of the right side panel 4 and the groove 3b of the bottom panel 3 respectively constitute a first panel pressing portion and a second panel pressing portion that press against each other.

[0107] Furthermore, as shown in Figure 16(c), the thickness of the hook receiving portion 35 may be set so that the second abutment portion 152 abuts against the frame 40, and the second abutment portion 152 of the hook portion 11 and the frame 40 to which the connecting aid 20 abuts may be configured to hold the hook receiving portion 35 in a narrow gap, or the hook receiving portion 35 may be configured as part of the frame of the bottom panel 3, for example. In this case, the frame 40 of the right side panel 4 and the hook receiving portion 35 of the bottom panel 3 respectively constitute a first panel pressing portion and a second panel pressing portion that press against each other.

[0108] As shown in FIGS. 16(b) and (d), the support portion 41 may be configured to include a support column fitting portion 44, and the support portion 12 may be configured to fit into the support column fitting portion 44. 16(d) is a plan view showing the shape of the support part 41 having the support post fitting part 44. The support post fitting part 44 is configured as an arc-shaped opening, and the diameter D of the arc of the support post fitting part 44 is set to be substantially the same as the diameter of the support part 12. Note that "substantially the same" means being the same taking into account manufacturing tolerances.

[0109] The chord length L of the arc of the support fitting portion 44 (the distance between the two insertion ends 45 of the support portion 12) is set to be shorter than the diameter D of the arc, and the height (width) H of the arc of the support fitting portion 44 is set to be larger than the radius of the support portion 12, and the support fitting portion 44 has a tapered shape on the insertion side of the support portion 12. This prevents the support portion 12 fitted into the support fitting portion 44 from slipping out.

[0110] Furthermore, a pillar guide portion 46 for guiding the insertion of the pillar portion 12 may be provided on the side of the pillar fitting portion 44 where the pillar portion 12 enters. The pillar guide portion 46 is configured so that its width increases outward from the insertion end portion 45 of the pillar portion 12. When the main coupler 10 and the auxiliary connection device 20 are moved to the support portion 41, the pillar portion 12 of the main coupler 10 is guided by the pillar guide portion 46 to the insertion end portion 45 and fits into the pillar fitting portion 44.

[0111] In this way, the right side panel 4 and the bottom panel 3 can be connected and fixed together with a simple operation using the main connector 10 and the auxiliary connector 20. Furthermore, since the connector 100 is made up of two main connectors 10 and an auxiliary connector 20, the connector 100 is easy to manufacture. Furthermore, it is possible to further improve the effect of preventing the main connector 10 from moving due to vibrations or the like caused by long-term use of the locker 1, causing the connection between the right side panel 4 and the bottom panel 3 to loosen.

[0112] [4-3] Connection and fixing procedure In this embodiment, the standard procedure for connecting and fixing the bottom panel 3 and the right side panel 4 using the connector 100 is as follows: (Step 1) As shown in FIG. 14(b), the support 12 of the main connector 10 is inserted through the opening 4d of the frame 40, the auxiliary connector 20, and the opening 21. (Step 2) As shown in FIGS. 15(a) and 16(a), the pressing portion 13 of the main connector 10 is rotated to place the pressing portion 13 on the pressed portion 23. (Step 3) As shown in FIG. 16(b), the main coupler 10 is slid so that the frame 40 and the hook receiving portion 35 are sandwiched between the auxiliary coupling device 20 and the hook portion 11. Through the above steps, the bottom panel 3 and the right side panel 4 can be easily fixed together. The order of (Step 2) and (Step 3) may be reversed. After the frame 40 and the hook receiving portion 35 are sandwiched between the connecting aid 20 and the hook portion 11, the pressing portion 13 of the main connecting device 10 may be rotated to strengthen the compressive force between the connecting aid 20 and the hook portion 11.

[0113] [4-4] Example of connector 2 Another embodiment in which the right main connector 10 is fixed to the side panel 4 will now be described. Figure 17 is a diagram showing the relationship between the right side panel 4 and the main coupler 10 and the connecting aid 20 to explain the coupler 100 of Example 2, where Figure 17(a) is an oblique view of the main coupler 10 and the connecting aid 20 arranged in a first position, and Figures 17(b) and (c) are an oblique view and a side view of the main coupler 10 and the connecting aid 20 arranged in a second position. In FIG. 17, the bottom panel 3 is omitted for the sake of visibility, but the right side panel 4 is combined with the bottom panel 3 in the same manner as in FIG.

[0114] 17(a), a support portion 41 is provided on a frame 47 of the right side panel 4. The frame 47 also has the effect of increasing the strength of the right side panel 4. The main coupler 10 is provided with a stopper 18 (retaining portion). The stopper 18 is rotatably attached to the support 12 on the side opposite the hook portion 11 of the support 12. For example, the operating portion 14 at the end of the support 12 may be configured as a cylinder, a stopper shaft 181 may be provided on the stopper 18, and a cylindrical cavity may be provided inside the stopper shaft 181 in which the cylinder is inscribed. FIG. 17(a) shows an example in which the stopper 18 extends in a direction (Y direction in the drawing) perpendicular to the moving direction of the main connector 10 (or the longitudinal direction of the connector assisting device 20).

[0115] As shown in FIGS. 17(b) and (c), the main coupler 10 is slid in the X direction in the drawing to the second position, and then the stopper 18 is rotated 90 degrees relative to the main coupler 10. The frame 47 (second frame) is provided with a stopper receiving portion 48 (stop receiving portion). The stopper receiving portion 48 is configured as a recess, and the stopper 18 fits (engages) with the stopper receiving portion 48.

[0116] As shown in Figure 17(c), the stopper 18 is configured in a T-shape. The width H1 of the recess in the stopper receiving portion 48 is smaller than the width H2 of the tip 181 of the stopper receiving portion 48. This prevents the main coupler 10 from sliding in the direction opposite to the X direction in the figure and the stopper 18 from slipping out of the stopper receiving portion 48. In other words, the stopper 18 cooperates with the stopper receiving portion 48 to prevent the main coupler 10 from moving. As a result, it is possible to further improve the effect of preventing the main connector 10 from moving due to vibrations or the like when the locker 1 is used for a long period of time, thereby preventing the connection between the right side panel 4 and the bottom panel 3 from loosening. In the process of connecting and fixing the bottom panel 3 and the right side panel 4 of the locker 1, the process of fitting the stopper 18 into the stopper receiving portion 48 is the final process.

[0117] In this way, by using the main connector 10 and the auxiliary connector 20, the right side panel 4 (first panel) and the bottom panel 3 (second panel) can be firmly fixed together with a simple operation, making it easy to assemble the locker 1.

[0118] [5] Effects The multi-tiered locker 500 according to this embodiment has a lower locker 1a and an upper locker 1b stacked and connected on top of the lower locker 1a, with these lockers 1a and 1b connected and secured together by side fasteners 501c and 501d. Here, side fastener 501c straddles the side surface of the bottom panel 3 of locker 1b and the top panel 2 of locker 1a, securing the connecting hole 4f in the right side panel 4 of lockers 1a and 1b. Side fastener 501d straddles the side surface of the bottom panel 3 of locker 1b and the top panel 2 of locker 1a, securing the connecting hole 7f in the left side panel 7 of lockers 1a and 1b.

[0119] These side fixing devices 501c, 501d can further prevent the upper lockers from falling due to external impacts, earthquakes, etc. Furthermore, since fixing devices 501c, 501d can be simply fitted into the multi-tiered locker 500 from the outside, it can be connected and fixed very easily.

[0120] Furthermore, in the multi-tiered locker 500 according to this embodiment, it is also possible to use side fasteners 501a and 501b to connect and fix the baseboard 8 to the lower locker 1a. This makes it possible to further strengthen the connection of the multi-tiered locker 500, thereby improving the effectiveness of preventing falls and tipping over.

[0121] Furthermore, the multi-tiered locker 500 according to this embodiment can be connected in two rows and two columns as shown in Fig. 11, or it is also possible to further connect two rows and two columns to the configuration of Fig. 11 as shown in Fig. 12. In this case, it is also possible to connect adjacent lockers 1 by fitting top fasteners 510, 520 into the connecting holes 2d of adjacent top panels 2. This makes it easy to connect and fix the lockers, and also improves the effect of preventing the upper lockers 1 from falling.

[0122] Furthermore, in the multi-stage locker 500 according to this embodiment, the base panel 8 has fixing holes 8e into which base fixing devices are fitted. By fitting the base fixing devices into the fixing holes 8e and the installation surface on which the multi-stage locker 500 is to be installed, the multi-stage locker 500 (base panel 8) can be more firmly fixed to the installation surface. This connects and fixes the multi-stage locker 500 to the installation surface, greatly improving the effect of preventing the multi-stage locker 500 from tipping over.

[0123] Furthermore, when the multi-tiered locker 500 according to this embodiment is used in a school or the like, there are cases where students purchase their own locker 1 when they enroll and take it home as a keepsake box when they graduate. In this case, while attending school, each student's locker 1 is stacked in multiple tiers or arranged in multiple rows in a predetermined location. In this case, by easily connecting and fastening multiple lockers 1 from the outside of the lockers 1 using fasteners 501, 510, and 520 as in this embodiment, the lockers 1 can be connected and fastened more firmly and easily without the contents of the lockers 1 being removed or exposed, as is the case when connecting and fastening from the inside of the lockers 1 (for example, Patent Document 3).

[0124] The locker 1 according to this embodiment also includes a connector 100. The connector 100 includes a main connector 10 and a connecting aid 20. The main connector 10 includes a hook portion 11 having a first abutment portion 151 and a second abutment portion 152, a support portion 12, and a pressing portion 13. The connecting aid 20 includes an insertion portion 21 having a support receiving portion 22 and a pressed portion 23 that receives the pressing portion 13. The right side panel 4 includes a first frame 40 and a second frame 47 disposed in a direction intersecting with the first frame 40. The first frame 40 has an opening 4d through which the support portion 12 is inserted, and the second frame 47 has a support portion 41 that contacts the support portion 12. The bottom panel 3 includes a hook receiving portion 35, and the connecting aid 20 and the first abutment portion 151 hold the first frame 40. The second contact portion 152 contacts the hook receiving portion 35 .

[0125] By configuring the locker 1 in this way, the connector 100 connects and fixes the right side panel 4 and bottom panel 3, which are the main components of the locker 1, by means of the hook portion 11 and the pressing portion 13 via the connecting aid 20. The right side panel 4 and bottom panel 3 can be easily fixed together by the rotation (turning) and sliding movement of the main connector 10.

[0126] In the locker 1 according to the present embodiment described above, the connecting aid 20 may have an inclined portion 24 that connects to the pressed portion 23. In this manner, the configuration of the connecting aid 20 having the pressed portion 23 and the inclined portion 24 makes it possible to easily and firmly connect the right side panel 4 and the bottom panel 3.

[0127] Furthermore, in the locker 1 according to this embodiment, the support portion 41 has a support post fitting portion 44, and the support portion 12 is shaped to fit into the support post fitting portion 44. By configuring the locker 1 in this manner, accidental displacement of the connector 100 can be effectively prevented, and a more stable connection between the right side panel 4 and the bottom panel 3 can be ensured.

[0128] Furthermore, in the locker 1 according to this embodiment, the main connector 10 has a stopper 18 rotatably mounted on the support 12, and the second frame 47 has a stopper receiving portion 48. The stopper 18 engages with the stopper receiving portion 48. By configuring the locker 1 in this way, it is possible to effectively prevent accidental displacement of the connector 100, and ensure a more stable connection between the right side panel 4 and the bottom panel 3.

[0129] Furthermore, in the locker 1 according to this embodiment, for example, a connector 100 is used to fasten the right side panel 4 and the bottom panel 3. This connector 100 has a main connector 10 and a connecting aid 20. The main connector 10 has a hook portion 11, a support portion 12, and a pressing portion 13, and the hook portion 11 has a first abutment portion 151 for contacting the right side panel 4 and a second abutment portion 152 for contacting the bottom panel 3. The connecting aid 20 has an insertion portion 21 through which the pressing portion 13 is inserted, a pressed portion 23, and an inclined portion 24 that includes the rotation range of the pressing portion 13 and is connected to the pressed portion 23. The insertion portion 21 has a support receiving portion 22 that rotatably supports the support portion 12. By using connector 100 having such a configuration, right side panel 4 and bottom panel 3, which are the main components of locker 1, can be firmly connected together through a simple assembly operation.

[0130] Furthermore, in the locker 1 according to this embodiment, for example, a connector 100 is used to fasten the right side panel 4 and the bottom panel 3 together. This connector 100 has a main connector 10 and a connecting aid 20. The main connector 10 has a hook portion 11, a support portion 12, a pressing portion 13, and a stopper 18 rotatably provided on the support portion 12.
