[0008] (Findings that formed the basis of this disclosure) At the time the inventors came up with the idea for the present disclosure, there was a technology in existence that included a cushioning member that abuts against the end of the washing machine's inlet and a foam member made of expanded polystyrene that is attached from above the cushioning member, so that when a large impact is applied, such as when a product is dropped during handling, causing the inner tub to shake significantly, the outer shape of the foam member abuts against the periphery of the inlet to regulate the shaking of the inner tub. In the prior art, polystyrene foam material was used as packaging material, but in recent years, environmental considerations have led to a preference for using cardboard instead of polystyrene foam. However, the inventors discovered the problem that cardboard cannot be used to form complex shapes, and that multiple cardboard boxes must be combined, or that assembly requires complex processes.In order to solve this problem, they came up with the subject matter of the present disclosure. Therefore, the present disclosure provides a cushioning member for packaging a washing machine that can suppress damage to components during assembly.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to the drawings.

[0011] [1-1.Configuration] [1-1-1. Washing machine configuration] Fig. 1 is a perspective view showing a washing machine in a state where the cushioning material for packaging according to embodiment 1 is attached, and Fig. 2 is a plan view showing a washing machine in a state where the cushioning material for packaging according to embodiment 1 is attached. 1 and 2, washing machine 10 of this embodiment has a rectangular cylindrical housing 11.

[0012] The housing 11 includes an upper frame 13. The upper frame 13 is provided on the top of the housing 11. The upper frame 13 is formed in a shape having an upper surface that slopes upward from the front to the rear. A lid (not shown) is provided on the upper frame 13 in an openable and closable manner. A cylindrical inner tank 15 with a bottom is housed inside the housing 11. The inner tank 15 is supported so as to be rotatable.

[0013] An operation panel 16 is provided at the rear of the upper frame. The operation panel 16 has a plurality of buttons 16a (shown in FIG. 1) that are used by the user to turn the power on / off, set the washing mode of the washing machine 10, and start operation.

[0014] [1-1-2. Composition of packaging cushioning materials] Fig. 3 is a perspective view showing the cushioning material for packaging according to the first embodiment. Fig. 4 is a developed view showing a first member of the cushioning material for packaging according to the first embodiment. Fig. 5 is a developed view showing a second member of the cushioning material for packaging according to the first embodiment. Fig. 6 is a perspective view showing the first member in an assembled state according to the first embodiment. Fig. 7 is a perspective view showing the second member in an assembled state according to the first embodiment.

[0015] 1 and 2, cushioning material for packaging 1 is a member that is attached between inner tub 15 and the inside of housing 11 of the washing machine, and that prevents inner tub 15 from moving relative to housing 11. When attached to the washing machine, cushioning material for packaging 1 supports inner tub 15 relative to housing 11. As shown in Figure 3, the cushioning packaging member 1 includes a first member 20 including a first pillar member 21 and a flat plate 22, and a second member 40 equipped with a second pillar member 41 arranged at a predetermined angle to the first pillar member 21 in a plan view. When the cushioning packaging member 1 is assembled, the first pillar member 21 and the second pillar member 41 intersect. The first member 20 and the second member 40 are made of cardboard. A first pillar member 21 is provided on the underside of the flat plate 22. In this embodiment, one side of the first pillar member 21 of the flat plate 22 is a first flat portion 23, and the other side of the first pillar member 21 of the flat plate 22 is a second flat portion 24.

[0016] As shown in FIG. 4, the first pillar member 21, the first flat portion 23, and the second flat portion 24 are integrally formed via bending lines 50, respectively. Then, by bending along the fold lines 50, the first member 20 is formed in which the flat plate 22 (first flat portion 23 and second flat portion 24) is positioned approximately perpendicular to the first pillar member 21 of a double structure erected in the vertical direction. In other words, as shown in Fig. 6, the first pillar member 21, the first flat portion 23 and the second flat portion 24 are formed by bending a single piece of cardboard.

[0017] As shown in Fig. 5, the second pillar member 41 is integrally formed via a folding line 50. The second pillar member 41 is formed as a double-structured second pillar member 41 by folding via the folding line 50. In other words, as shown in Fig. 7, the second pillar member 41 is formed by folding a single piece of cardboard.

[0018] An insertion groove 25 extending in the vertical direction is formed on the underside of the first pillar member 21. An insertion notch 42 corresponding to the insertion groove 25 is formed in the upper part of the second pillar member 41. Then, with the insertion groove 25 of the first pillar member 21 and the insertion notch 42 of the second pillar member 41 combined, the second pillar member 41 is configured to be rotatable along the underside of the flat plate 22 relative to the first pillar member 21.

[0019] A first abutment surface 26 is formed on each end of the first pillar member 21. The distance between each first abutment surface 26 is formed to be approximately the same as the inner diameter of the inner tub 15 of the washing machine. A first support protrusion 27 that protrudes outward is formed above each first abutment surface 26. The first support protrusion 27 abuts against the upper edge of the inner tub 15 of the washing machine.

[0020] A first curved portion 28 formed in a curved shape is provided on a first outer edge 23a of the first flat surface portion 23. A second curved portion 29 formed in a substantially curved shape is provided on a second outer edge 24a of the second flat surface portion 24. The first curved portion 28 and the second curved portion 29 are formed so that their curved lengths are different. A first stopper 30 serving as a rotation restricting portion is formed to protrude radially outward at the end of the first curved portion 28. Similarly, a second stopper 31 serving as a rotation restricting portion is formed to protrude radially outward at the end of the second curved portion 29.

[0021] A front engagement member 32 is provided on the first outer edge 23a of the first flat plate portion. The front engagement member 32 is composed of an extension portion 33 extending downward from the first flat surface portion 23, and a front engagement piece 34 extending from one side of the extension portion 33 to the outside of the first flat surface portion 23. The front engaging member 32 is formed by bending it along a bending line 50 .

[0022] A first engaging portion 43 and a second engaging portion 44 are formed on the upper ends of both ends of the second pillar member 41. The first engaging portion 43 and the second engaging portion 44 engage with the first outer edge 23a of the first flat portion 23 and the second outer edge 24a of the second flat portion 24. The first engaging portion 43 and the second engaging portion 44 are each composed of a rising portion 45 extending upward from the end of the second pillar member 41 and a locking claw 46 extending from the rising portion 45 to the upper surface side of the flat plate 22.

[0023] The distance from the center of rotation of the first pillar member 21 and the second pillar member 41 to the rising portion 45 of the first engagement portion 43 is formed to correspond to the radius of the first curved portion . In addition, the distances from the rotation center of the first pillar member 21 and the second pillar member 41 to the rising portion 45 of the second engagement portion 44 are formed to be different. That is, the distance from the center of rotation with the second pillar member 41 to the rising portion 45 of the first engaging portion 43 is longer than the distance to the rising portion 45 of the second engaging portion 44.

[0024] Below the first engaging portion 43 and the second engaging portion 44 of the second pillar member 41, a second contact surface 47 is formed. The distance between each second contact surface 47 is formed to be approximately the same as the inner diameter of the washing machine's inner tub 15. Second support protrusions 48 that protrude outward are formed above each second contact surface 47. Second support protrusions 48 come into contact with the upper edge of the washing machine's inner tub 15.

[0025] In this embodiment, when the second pillar member 41 is rotated along the underside of the flat plate 22 relative to the first pillar member 21 with the insertion groove 25 of the first pillar member 21 and the insertion notch 42 of the second pillar member 41 combined, the first engaging portion 43 of the second pillar member 41 begins to engage with the first curved portion 28 of the first flat portion 23. In this state, the second engaging portion 44 of the second pillar member 41 is not engaged with the second curved portion 29 of the second flat portion 24. When the second pillar member 41 is further rotated, the second engaging portion 44 of the second pillar member 41 also begins to engage with the second curved portion 29 of the second flat portion 24. Furthermore, the second pillar member 41 is rotated until the first engaging portion 43 and the second engaging portion 44 come into contact with the first stopper 30 and the second stopper 31, and the cushioning material for packaging 1 is completed.

[0026] The first flat portion 23 and the second flat portion 24 are formed with restricting pieces 35 for preventing the second pillar member 41 from rotating in the opposite direction (clockwise in the figure) from a state in which the first engaging portion 43 and the second engaging portion 44 of the second pillar member 41 are abutted against the first stopper 30 and the second stopper 31. The restriction piece 35 is formed by bending the first flat portion 23 and the second flat portion 24 downward along the bending line 50 .

[0027] [1-2. Effect] Next, the operation of the first embodiment will be described. Fig. 8 is an explanatory diagram showing the assembly process of the cushioning packing member 1. Fig. 9 is a partial cross-sectional view showing the state in which the cushioning packing member is attached to the washing machine in the first embodiment. First, in this embodiment, the first member 20 is bent along the bending line 50 from the state shown in FIG. 4 to form the flat plate 22, the first pillar member 21, and the front engaging member 32. Furthermore, the second member 40 is bent along the bending line 50 from the state shown in FIG. After that, with the insertion groove 25 of the first pillar member 21 and the insertion notch 42 of the second pillar member 41 combined, the second pillar member 41 is rotated counterclockwise, which is the first direction in Fig. 6(a), along the underside of the flat plate 22 relative to the first pillar member 21. This state is shown in Fig. 6(b).

[0028] As the second pillar member 41 is rotated, the first engaging portion 43 of the second pillar member 41 begins to engage with the first curved portion 28 of the first flat portion 23, as shown in Fig. 6(c). In this state, the second engaging portion 44 of the second pillar member 41 is not engaged with the second curved portion 29 of the second flat portion 24. When the second pillar member 41 is further rotated, the second engaging portion 44 of the second pillar member 41 also begins to engage with the second curved portion 29 of the second flat portion 24. Furthermore, the second pillar member 41 is rotated until the first engaging portion 43 and the second engaging portion 44 come into contact with the first stopper 30 and the second stopper 31. Then, the restricting piece 35 is bent downward to prevent the second pillar member 41 from rotating clockwise, which is the second direction opposite to the first direction, thereby completing the packaging cushioning material 1 as shown in Figure 6(d).

[0029] In this state, the first flat portion 23 and the second flat portion 24 are formed by being bent relative to the first pillar member 21, and therefore, due to the restoring force of the cardboard, an upward force acts on the first outer edge 23a and the second outer edge 24a of the first flat portion 23 and the second flat portion 24. Therefore, the first and second flat portions 23 and 24 are subjected to a force that causes them to abut against the locking claws 46 of the first and second engaging portions 43 and 44 of the second pillar member 41, thereby making it possible to firmly hold the first member 20 and the second member 40 together.

[0030] The cushioning member for packaging 1 configured in this manner is engaged with the upper edge portion of the inner tub 15 of the washing machine, as shown in FIGS. Specifically, the first contact surface 26 of the first pillar member 21, the second contact surface 47 of the second pillar member 41, and the front engagement member 32 are brought into contact with the upper inner surface of the inner tank 15. In this state, the first support protrusion 27 of the first pillar member 21, the second support protrusion 48 of the second pillar member 41, and the front engagement piece 34 of the front engagement member 32 come into contact with the inner surface of the housing 11. As a result, the position of the inner tank 15 relative to the housing 11 can be regulated by the first pillar member 21, the second pillar member 41 and the front engagement member 32.

[0031] [1-3. Effects, etc.] As described above, the packaging cushioning member 1 for a washing machine in this embodiment includes the first pillar member 21 (first support member) and the second pillar member 41 (second support member) that support the housing 11 and the inner tub 15, and the first member 20 that supports the first pillar member 21 and the second pillar member 41, and is assembled by rotating the first pillar member 21 or the second pillar member 41 relative to the first member 20. As a result, when assembling the cushioning material for packaging 1, there is no need to bend and assemble the first pillar member 21, the second pillar member 41, and the first member 20, so assembly is easy, the cardboard is prevented from breaking during the assembly work, and the strength of the cushioning material for packaging 1 can be ensured.

[0032] In addition, in the cushioning member for packaging 1 for a washing machine of this embodiment, the first member 20 and the first pillar member 21 (first support member) are integrally formed. This allows assembly using two members, the first member 20 that is integral with the first pillar member 21, and the second pillar member 41, reducing the number of joining points between each member and ensuring the strength of the cushioning material for packaging 1. Furthermore, because only a small number of parts are required, assembly is easy even if there is variation in the dimensional precision of each member.

[0033] In addition, in the packaging cushioning member 1 of the washing machine of this embodiment, the second pillar member 41 (second support member) is assembled by rotating in the first direction relative to the first pillar member 21 (first support member) and the first pillar member 21 (first support member). This improves the ease of assembling the cushioning material for packaging 1. Furthermore, by assembling the cushioning material for packaging 1 by rotating it in the first direction relative to the flat plate 22, the first pillar member 21 and the second pillar member 41 can be assembled with their height positions at approximately the same level.

[0034] In addition, in the packaging cushioning member 1 of the washing machine of this embodiment, the first member 20 is formed with a first stopper 30 and a second stopper 31 (rotation restriction portion) that restricts the second pillar member 41 (second support member) from rotating in the first direction beyond a predetermined position. As a result, by rotating the second pillar member 41 until it abuts against the first stopper 30 and the second stopper 31, the second pillar member 41 can be positioned at a predetermined position relative to the first member 20.

[0035] In addition, in the packaging cushioning member 1 for the washing machine of this embodiment, the second pillar member 41 (second support member) is formed with a first engagement portion 43 and a second engagement portion 44 (engagement portion) that engage with the first outer edge 23a (outer edge) of the first member 20, and the first outer edge 23a of the first member 20 is formed with a first curved portion 28 and a second curved portion 29 (curved portion) that are curved around the center of rotation of the second pillar member 41. This allows the first engagement portion 43 and the second engagement portion 44 to be moved along the first curved portion 28 and the second curved portion 29 when assembling the second pillar member 41 by rotating it along the first outer edge 23a of the first member 20, and the first engagement portion 43 and the second engagement portion 44 can be easily engaged with the first outer edge 23a of the first member 20.

[0036] In addition, in the packaging cushioning member 1 for a washing machine of this embodiment, the outer edge of the first member 20 includes a first outer edge 23a and a second outer edge 24a opposite the first outer edge 23a across the first pillar member 21 (first support member), and the distance between the first curved portion 28 (curved portion) formed on the first outer edge 23a and the center of rotation of the second pillar member 41 (second support member) is different from the distance between the second curved portion 29 (curved portion) formed on the second outer edge 24a and the center of rotation of the second pillar member 41, and the engagement portion of the second pillar member 41 has a different distance from the center of rotation of the second pillar member 41 corresponding to the first curved portion 28 of the first outer edge 23a and the second curved portion 29 of the second outer edge 24a. This allows the first engaging portion 43, which engages with the first outer edge 23a of the first member 20, and the second engaging portion 44, which engages with the second outer edge 24a of the first member 20, to be engaged at different rotational positions of the second pillar member 41. Therefore, during assembly, it is possible to check whether each engaging portion is engaged with the first member 20.

[0037] In addition, in the packaging cushioning member 1 of the washing machine of this embodiment, the first member 20 is provided with a regulating piece 35 that regulates the second pillar member 41 (second support member) from rotating in a second direction opposite to the first direction after it reaches a predetermined position. As a result, after the first member 20 rotates the second pillar member 41 in the first direction to a predetermined position, the restricting piece 35 can restrain the second pillar member 41 from rotating in the second direction.

[0038] In addition, in the packaging cushioning member 1 of the washing machine of this embodiment, a first abutment surface 26 that abuts against the inner tub 15 is formed at both ends of the first pillar member 21 (first support member), a second abutment surface 47 that abuts against the inner tub 15 is formed at both ends of the second pillar member 41 (second support member), and a front engagement member 32 (abutment portion) that abuts against the housing is provided on the outer edge of the first member 10. As a result, the position of the inner tank 15 relative to the housing 11 can be regulated by the first contact surface 26 of the first pillar member 21, the second contact surface 47 of the second pillar member 41, and the front engagement member 32.

[0039] In the cushioning packaging member 1 for the washing machine of this embodiment, the first member 20, the first pillar member 21 (first support member), and the second pillar member 41 (second support member) are made of cardboard. This allows the cushioning material for packaging 1 to be easily assembled using cardboard, prevents the cardboard from breaking during the assembly work, and ensures the strength of the cushioning material for packaging 1.

[0040] As described above, the above-mentioned first embodiment has been described as an example disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made.
