Summary of the Invention

Problems to be Solved by the Invention

[0004] In the support of Patent Document 1, several steps are required as an assembly procedure. One of the steps is to insert the holding part of the support into the mounting hole from the back side of the wall plate material, leaving the base part on the back side. In order to insert it securely from the back side of the wall plate material, it is desirable to insert it after turning the wall plate material over. In Patent Document 1, instead of directly drilling a mounting hole in the wall plate material of the storage container, on the premise of arranging an interior pad in the storage container, a mounting hole is drilled in advance in the wall plate material of the interior pad and the support is attached. The interior pad is lighter than the storage container and is relatively easy to turn over, but the labor of turning it over and then inserting it occurs. On the other hand, when it is desired to provide a mounting hole in the storage container itself and attach the support, the storage container must be turned over and the support must be attached. Furthermore, it is also necessary to maintain the support so that it does not fall off during the process of returning the turned-over storage container to its original state.

[0005] The object of the present invention is to provide a support that can be easily attached from above to mounting holes opened in a wall panel that defines a part of the orientation of the storage space, thereby supporting the interior material. The object of the present invention is also to provide a method for assembling the interior of a storage container using this support. [Means for solving the problem]

[0006] According to the present invention, the support is attached to a mounting hole in a wall panel that defines the orientation of a part of the storage space for storing articles, and is used to fix interior materials placed in the storage space to the wall panel, The aforementioned support is A pair of first and second pieces, each having a planar L-shaped base and a holding part, are assembled back-to-back and are able to swing relative to each other with respect to the L-shaped vertex. On the opposing connecting sides when the single-sided holding portions face each other, a male connecting shaft is provided on one connecting side and a female connecting shaft is provided on the other connecting side at the same height from the axis, and the male connecting shaft and the female connecting shaft are connectable when the connecting sides face each other. The support is characterized in that the first piece and the base portion of the second piece are inserted into the mounting hole on the back side of the wall panel material, and the male connecting shaft and the female connecting shaft are inserted into insertion holes provided in the interior material on the front side of the wall panel material to connect them.

[0007] Furthermore, according to the present invention's method for assembling the interior of a storage container, the interior materials to be placed in the storage space are fixed to the wall panel by a support attached to a mounting hole in the wall panel that defines a part of the orientation of the storage space for storing articles, The support consists of a pair of first and second pieces, each having a planar L-shaped base and a holding portion, which are assembled back-to-back and pivotable around the L-shaped apex as the axis. A male connecting shaft is provided on one connecting side and a female connecting shaft on the other connecting side, at the same height from the axis on each of the opposing connecting sides when the holding portions face each other. The male and female connecting shafts can be connected when the connecting sides face each other. The interior material is provided with an insertion hole, Insert the first piece and the second piece into the mounting hole, with one base portion of each piece in close proximity, and insert them into the back side of the wall panel material. The wall panel material is characterized by being connected by inserting the male connecting shaft and the female connecting shaft into insertion holes provided in the interior material on the front side of the wall panel material. [Effects of the Invention]

[0008] According to the present invention, a support can be attached to the mounting hole in the bottom plate on the side of the storage space where the interior material is to be installed. Therefore, there is no need to turn the wall panel over. [Brief explanation of the drawing]

[0009] [Figure 1] This is a perspective view of a storage container in which partition plates and cushioning materials are installed using the support fixture of this embodiment. [Figure 2] This is a perspective view of the support. [Figure 3] This diagram shows how the support structure is assembled. [Figure 4] This diagram illustrates the method of assembling the interior of a containment container using support fixtures. [Figure 5] This diagram illustrates the details of the male and female key sections. [Modes for carrying out the invention]

[0010] Referring to Figure 1, an example of a support 10 and a storage container 1 equipped therewith will be described. The articles to be stored in the storage container 1 (hereinafter referred to as "stored articles") are diverse. Examples of stored articles include vehicle parts, electronic and electrical components, and resin materials. The support 10 arranges partition plates or cushioning materials, etc., inside the storage container 1. The difference between cushioning materials and partition plates is that cushioning materials are intended to protect the stored articles, while partition plates are intended to divide space. Since they are substantially the same as members that are placed inside and fixed in the storage container 1, they will be referred to as "interior materials 20" below. The shape of the storage container 1 can be arbitrarily selected. In one example, the storage container 1 is box-shaped.

[0011] In Figure 1A, the storage container 1 has a storage space 4 for storing items. Five of the six directions of the storage space 4 are defined by wall panels. The storage container 1 is equipped with a bottom plate 2 and four side plates 3 connected to the bottom plate 2, which constitute the wall panels. The storage space 4 of the storage container 1 has no wall panels above it, forming an opening 5 for loading and unloading items stored in the storage space 4. The storage space 4 of the storage container 1 can be enclosed in all six directions by separately attaching a lid (not shown) to the opening 5 as needed.

[0012] An interior pad 10, shown in Figure 1B, is installed inside the storage container 1. The interior pad 10 is a component introduced in Patent Document 1. The interior pad 10 is provided for positioning the support 30. The interior pad 10 is placed inside the wall material of the storage container 1. The wall material of the interior pad 10 is a bottom plate 11 and a pair of side plates 12, and three of the six orientations of the storage space 4 are defined by the wall material. If the support 30 is directly attached to the wall material of the bottom plate 2 or side plates 3 of the storage container 1, processing of the storage container 1 is required, but if the interior pad 10 is used, such processing is performed on the interior pad 10, and processing of the storage container 1 is not required. The interior pad 10 can be configured in various ways, such as having only the bottom plate 11, or only the bottom plate 11 and side plates 12, so that some orientations of the storage space 4 in which the items are stored are defined by the wall material.

[0013] The wall panel material constituting the interior pad 10 can be arbitrarily selected. In this embodiment, the material constituting the interior pad 10 is a lightweight material that can be easily carried by the user. Preferred examples of wall panel material constituting the interior pad 10 are synthetic resin and corrugated cardboard. Examples of synthetic resin are polypropylene resin and polyethylene resin. The bottom plate 11 and side plates 12 are the wall panel material of the interior pad 10, and one or both of the bottom plate 11 and side plates 12 are provided with one or more rectangular mounting holes 13 to which a support 30 is attached as needed.

[0014] Figure 1C shows the interior material 20. An example of the interior material 20 shown is a cushioning material. The interior material 20, acting as a cushioning material, protects the stored items from damage. The materials constituting the interior material 20 can be arbitrarily selected. In a preferred example, the materials constituting the interior material 20 are lightweight and soft materials that do not damage the stored items. A preferred example of materials constituting the interior material 20 is synthetic resin and corrugated cardboard. An example of synthetic resin is urethane resin and olefin resin.

[0015] The shape of the interior material 20 can be arbitrarily selected according to the type of items to be stored. In this embodiment, one interior material 20 comprises a rectangular parallelepiped base 21 and four rectangular parallelepiped protrusions 22 projecting from the base 21. The base 21 is erected on the bottom plate 11 by a support 30. Items to be stored are placed between the protrusions 22. Insertion holes 23, each consisting of two insertion holes 23, are provided along the bottom edge of the base 21. Insertion holes 23 are also provided along the sides of the protrusions 22 at both ends. Similarly, if the interior material 20 is a partition plate, multiple sets of two insertion holes 23 can be provided.

[0016] Fig. 1D shows the support 30. The support 30 supports the interior material 20. The support 30 has a holding part 50 having a male connecting shaft 60 and a female connecting shaft 70 that engage with the insertion hole 23 of the interior material 20, and a flat base part 40 that supports the holding part 50. The holding part 50 is protruded leaving the base part 40 from the mounting hole 13 opened in the bottom plate 11, and engages with the insertion hole 23 of the interior material 20 by the male connecting shaft 60 and the female connecting shaft 70. The support 30 is formed by combining a pair of L-shaped parts consisting of a first piece 31 and a second piece 32 back to back with each other. The first piece 31 and the second piece 32 are swingable relative to each other about the axis c at the L-shaped vertex position. The base part 40 is formed by a single base part 41 of the first piece 31 and a single base part 41 of the second piece, and the holding part 50 is formed by a single holding part 51 of the first piece 31 and a single holding part 51 of the second piece 32.

[0017] The material constituting the support 30 can be arbitrarily selected. In a preferred example, the material constituting the support 30 is a lightweight material that can be easily carried by the user. A preferred example of the material constituting the support 30 is a synthetic resin. An example of the synthetic resin is polypropylene resin and acrylonitrile-butadiene-styrene resin (ABS resin). The support 30 includes a base part 40 and a holding part 50. The support 30 is integrally formed with the base part 40 and the holding part 50, for example, by injection molding.

[0018] Fig. 2 is an enlarged perspective view of the support 30. In Fig. 2A, the three-dimensional directions are shown as x, y, and z. In the present embodiment, the first piece 31 and the second piece 32 are members having the same shape and structure. Therefore, hereinafter, the first piece 31 will be described representatively. The first piece 31 has a single base part 41 and a single holding part 51 that are each planar. The single base part 41 and the single holding part 51 are connected in an L shape, and the single base part 41 has a planar shape that extends in the xy direction. Also, the single holding part 51 has a planar shape that extends in the xz direction. The surface of the single holding part 51 facing the y-direction side opposite to the single base part 41 is defined as the connecting side surface 52 (see Fig. 2A), and the back side is defined as the back surface 53 (see Fig. 2B).

[0019] On the side of the connecting side surface 52, one or more shaft portions 42 and one or more bearing portions 43 are provided alternately along the axis c extending in the x direction on the y-direction extension line of the single base portion 41. The bearing portion 43 includes a U-shaped groove 44 with an open lower side in the Z direction and can receive the shaft portion 42. When the connecting side surfaces 52 of the first piece 31 and the second piece 31 are opposed to each other, on the axis c, the shaft portion 42 on the side of the first piece 31 is received by the bearing portion 43 on the side of the second piece 32, and the shaft portion 42 on the side of the second piece 32 is received by the bearing portion 43 on the side of the first piece 31.

[0020] Also, one male connecting shaft 60 and one female connecting shaft 70 are provided on the connecting side surface of each of the single holding portions 51. The male connecting shaft 60 and the female connecting shaft 70 are provided at the same height position in the z direction with respect to the axis c. The male connecting shaft 60 and the female connecting shaft 70 are configured such that a plurality of male key portions 61 and female key portions 71 are respectively arranged around the center r of their respective through holes 35. The male key portion 61 has a T shape with a tip that spreads in the circumferential direction. The female key portion 71 has a recess q for receiving the tip p of the male key portion 61 that protrudes in the circumferential direction in this T shape.

[0021] The shaft portions 42 of the first piece 31 and the second piece 32 are arranged so as to be received by the bearing portions 43, and when the single holding portion 51 of the first piece 31 and the single holding portion 51 of the second piece 32 are faced to each other and the connecting side surface 52 of the first piece 31 and the connecting side surface 52 of the second piece 32 are opposed to each other, the male connecting shaft 60 and the female connecting shaft 70 are connected. Incidentally, the recess 54 on the side of the connecting side surface 52 is a gap for inserting a jig (not shown) to peel off the male connecting shaft 60 and the female connecting shaft 70.

[0022] Figure 3 shows how the support 30 is assembled. In Figure 3A, the shaft portion 42 and bearing portion 43 of the first piece 31 are fitted into the bearing portion 43 and shaft portion 42 of the second piece 32, respectively. Once fitted together, the axes c coincide, and the first piece 31 and the second piece 32 become able to swing relative to each other around axis c (Figure 3B). Then, when the connecting side surface 52 of the first piece 31 and the connecting side surface 52 of the second piece 31 are brought into contact, the male connecting shaft 60 and the female connecting shaft 70 overlap, and the male key portion 61 of one piece fits one-to-one with the female key portion 71 of the other piece, thereby connecting them (Figure 3C).

[0023] Figure 4 illustrates the method of assembling the interior of the container 1 using the support 30. After fitting the shaft portion 42 and bearing portion 43 of the first piece 31 and the second piece 32 into place, the base portions 41 of both are brought close together and inserted into the mounting hole 13 of the interior pad 10 from the top to the back (Figure 4A). On the front side of the mounting hole 13, the interior material 20 is positioned between the connecting side 52 of the first piece 31 and the connecting side 52 of the second piece 32 (Figure 4B). Subsequently, the male connecting shaft 60 and female connecting shaft 70 of the first piece 31 and the second piece 32 are inserted into the insertion hole 23 of the interior material 20, connecting the male connecting shaft 60 and the female connecting shaft 70. As the connecting side 52s of the first piece 31 and the second piece 32 move closer together, the interior material 20 is pulled towards the interior pad 10 and fixed in an upright position away from the interior pad 10 (Figure 4C).

[0024] According to the support 30 of this embodiment, the installation of the support 30 to the mounting hole 13 of the interior pad 10 does not require turning the interior pad 10 upside down; it can be done from the top side of the interior pad 10. That is, the installation side is the same top side of the interior pad 10 as the installation side of the interior material 20. Therefore, the installation of the support 30 and the interior material 20 can be done in one step, making it simple.

[0025] In this embodiment, an arrangement using the interior pad 10 is shown, but the interior pad 10 is not necessary if mounting holes 13 for attaching the support 30 can be machined into the storage container 1. In this case, the mounting holes 13 are drilled into either or both of the wall panels of the bottom plate 2 and / or side plates 3 of the storage container 1.

[0026] Even when drilling mounting holes 13 in the container 1, there is no need to turn the container 1 upside down; the support 30 can be installed from the storage space 4 side of the container 1. This is the same side from which the interior material 20 is installed. To ensure enough space for the base portion 41 to rotate, one can, for example, slightly lift the container 1 or place it on a wire rack, which is easier than turning it upside down. Being able to work from the storage space 4 side of the container 1 is even more effective when the container 1 is large or heavy.

[0027] The shapes of the male key portion 61 and the female key portion 71 will be further explained using Figure 5. First, in this embodiment, as shown on the right in Figure 5A, the male key portion 61 is T-shaped with its tip p widening in the circumferential direction. The female key portion 71 has a recess q that receives the tip p of this T-shaped male key portion 61. The tip p remains at the radial position where the male key portion 61 is located, without moving away from the center r of the through hole 35. In contrast, as shown on the left in Figure 5A, it is conceivable to provide the tip p' of the male key portion 61' so that it protrudes outward by a length m from the radial position where the key portion 61 is located. However, in the configuration shown on the left in Figure 5A, when the male key portion 61' overcomes the female key portion 71' to engage, there is a risk of friction and deformation, which in turn leads to a decrease in the strength of both key portions. According to the configuration shown on the right in Figure 5A, the shape of the male key portion 61 is T-shaped, and there is no tip p that acts as a key in the direction of overcoming, so when the male key portion 6 overcomes the female key portion 7 to engage, there is less risk of friction and deformation, and the strength can be kept almost constant.

[0028] Furthermore, in this embodiment, as shown on the right in Figure 5B, slits S are provided on both sides of the base of the male key portion 61, moving away from the center r (Figure 2 shows both slits S). Due to the provision of slits S, the pivot center sw of the male key portion 61 is shifted to the tip position of the slit S (the position furthest from the center r). On the other hand, as shown on the left in Figure 5B, if slits S are not provided, the pivot center position sw' of the male key portion 61' is directly below the male key portion 61'. When the force indicated by arrow F is applied by the female key portion, the male key portion 61' tilts from the pivot center sw' towards the center r (see dashed line). The tilt towards the center r is in the direction away from the female key portion. As shown on the right in Figure 5B, when slits S are provided, the pivot center position sw of the male key portion 61 is at a position further from the center r than the position of the force indicated by arrow F applied by the female key portion. Therefore, the male key portion 61 is tilted away from the pivot center sw towards the center r (see dashed line). In this way, according to the configuration shown on the right of Figure 5B, the male key portion 61 is less likely to come off the female key portion 71, and acts in a direction that strengthens the mating of the key portions.

[0029] Furthermore, according to this embodiment, as shown in Figure 5C, multiple female key parts 61 and 71 (four in this example) are arranged around the through hole 35. Therefore, no matter which direction a force is applied to separate the key parts, it is possible to prevent any of the key parts from coming apart.

[0030] In this embodiment, if the connection between the male connecting shaft 60 and the female connecting shaft 70 is to be made even stronger, a resin rivet (for example, Panlock® manufactured by Kunimori Chemical Co., Ltd.) may be inserted and fixed through the through-hole in the center of the male connecting shaft 60 and the female connecting shaft 70.

[0031] In this embodiment, the first piece 31 and the second piece 32 are identical in shape and structure, but this can be changed. For example, one or more male connecting shafts 60 may be provided on the first piece 31 side, and one or more female connecting shafts 70 may be provided on the second piece 32 side, corresponding to the first piece 31. Alternatively, only the shaft portion 42 may be provided on the first piece 31 side, and only the bearing portion 43 may be provided on the second piece 32 side. The reverse is also possible. However, in this case, since the first piece 31 and the second piece 32 are not identical in shape and structure, two types of parts management will be required. [Explanation of Symbols]
