Description

[Technical field]

[0001] The present invention relates to a support and a method for assembling the interior of a storage container using the support. [Background technology]

[0002] As a support for fixing interior materials such as partitions and cushioning materials inside a storage container, for example, a support disclosed in Patent Document 1 is known. This support is fixed to a wall panel that defines the orientation of a portion of the storage space, and has a holding part for hanging the partitions, cushioning materials, etc., and a flat base part that supports the holding part. The support is fixed with the holding part protruding from a mounting hole drilled in the wall panel, leaving the base part, and the interior materials are hung on the holding part.

[0003] [Patent Document 1] Patent No. 7105000 Summary of the Invention [Problem to be solved by the invention]

[0004] The support of Patent Document 1 requires several steps 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 panel, leaving the base part on the back side. In order to reliably insert the support from the back side of the wall panel, it is desirable to turn the wall panel upside down before inserting it. In Patent Document 1, mounting holes are not directly drilled in the wall panel of the storage container, but rather, it is assumed that an interior pad is placed inside the storage container, and mounting holes are drilled in the wall panel of the interior pad in advance to attach the support. The interior pad is lighter than the storage container and is relatively easy to turn over, but it is troublesome to turn it over and then insert it. On the other hand, if it is desired to provide a mounting hole in the storage container itself and attach the support, the storage container must be turned upside down and the support must be attached. In addition, it is also necessary to maintain the support so that it does not fall off during the process of returning the 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 a mounting hole opened in a wall panel material that defines the orientation of a portion of the storage space, and can support an interior material, and also to provide a method of assembling the interior of a storage container using this support. [Means for solving the problem]

[0006] According to the present invention, there is provided a support device which is attached to a mounting hole of a wall panel material which defines an orientation of a portion of a storage space for storing an item, and which fixes an interior material to be placed in the storage space to the wall panel material, The support includes: A pair of first and second pieces, each having a base portion and a holding portion connected in a planar L-shape, are assembled back-to-back and can swing relative to each other about the apex of the L-shape as an axis; and a male connecting shaft is provided on one connecting side surface and a female connecting shaft is provided on the other connecting side surface at the same height position from the axis on each connecting side surface that faces each other when the one holding portions face each other, and the male connecting shaft and the female connecting shaft are connectable when the connecting side surfaces face each other, The support is inserted into the back side of the wall panel with one base portion of the first piece and one base portion of the second piece adjacent to the mounting hole, 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 to connect them.

[0007] According to a method for assembling an interior of a storage container of the present invention, an interior material to be placed in a storage space is fixed to a wall panel material by a support attached to a mounting hole of the wall panel material that defines an orientation of a portion of the storage space for storing an article, the method comprising the steps of: The support device is assembled back-to-back with a pair of first and second pieces, each having a one-side base portion and one-side holding portion connected in a planar L-shape, and is capable of swinging relative to one another around an axis that is the apex of the L-shape. A male connecting shaft is provided on one connecting side surface and a female connecting shaft is provided on the other connecting side surface at the same height from the axis on each connecting side surface that faces when the one-side holding portions face each other, and the male connecting shaft and the female connecting shaft are connectable when the connecting side surfaces face each other, The interior material is provided with an insertion hole, the first piece and the second piece are inserted into the mounting hole at the rear side of the wall panel while the base portions of the first piece and the second piece are in close proximity to each other; The male connecting shaft and the female connecting shaft are connected by being inserted into insertion holes provided in the interior material on the front side of the wall panel. Effect of the Invention

[0009] [Figure 1] 1 is a perspective view of a storage container in which a partition plate and a cushioning material are installed using the support device of this embodiment. FIG. [Diagram 2] FIG. [Diagram 3] FIG. 13 is a diagram showing how the support is assembled. [Figure 4] 13A to 13C are diagrams illustrating a method for assembling the interior of a storage container using supports. [Diagram 5] FIG. 2 is a diagram illustrating the details of the male and female keys. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] With reference to FIG. 1, an example of a support 10 and a storage container 1 equipped with the support will be described. The items (hereinafter referred to as "stored items") stored in the storage container 1 are diverse. Examples of stored items are vehicle parts, electronic / electrical parts, and resin materials. The support 10 arranges a partition plate or a buffer material, etc., in the storage container 1. The difference between the buffer material and the buffer plate is that the buffer material is intended to protect the stored items, while the buffer plate is intended to divide the space, and since they are essentially the same as members arranged and fixed inside the storage container 1, they will be referred to as "interior material 20" below. The shape of the storage container 1 can be selected arbitrarily. In one example, the storage container 1 is box-shaped.

[0011] In FIG. 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 has a bottom plate 2 and four side plates 3 connected to the bottom plate 2, which form the wall panels. There is no wall panel above the storage space 4 of the storage container 1, and this serves as an opening 5 for inserting and removing items stored in the storage space 4. The storage space 4 of the storage container 1 can be surrounded in all six directions by separately attaching a lid (not shown) to the opening 5 as necessary.

[0012] An interior pad 10 shown in FIG. 1B is installed in the storage container 1. The interior pad 10 is a member introduced in Patent Document 1. The interior pad 10 is provided for positioning the support 30. The interior pad 10 arranges a wall plate inside the wall plate of the storage container 1. The wall plate of the interior pad 10 is a bottom plate 11 and a pair of side plates 12, and three of the six directions of the storage space 4 are defined by the wall plate. When the support 30 is directly attached to the wall plate of the bottom plate 2 or the side plate 3 of the storage container 1, processing of the storage container 1 side is required, but when the interior pad 10 is used, such processing is performed on the interior pad 10, and processing of the storage container 1 side is not required. The interior pad 10 is defined by the wall plate in various ways, such as when only the bottom plate 11 is used, or when only the bottom plate 11 and the side plate 12 are used.

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

[0014] FIG. 1C shows an interior material 20. An example of the interior material 20 shown in the figure is a cushioning material. The interior material 20 as a cushioning material protects the stored items from being damaged. The material constituting the interior material 20 can be selected arbitrarily. In a preferred example, the material constituting the interior material 20 is a lightweight, soft material that does not damage the stored items. Preferred examples of the material constituting the interior material 20 are synthetic resin and cardboard. Examples of synthetic resins are urethane resin and olefin resin.

[0015] The shape of the interior material 20 can be selected arbitrarily depending on the type of stored goods. In this embodiment, one interior material 20 has a rectangular parallelepiped base 21 and four rectangular parallelepiped protruding parts 22 protruding from the base 21. The base 21 is erected on the bottom plate 11 by the support 30. Stored goods are placed between the protruding parts 22. Along the bottom side of the base 21, insertion holes 23 are provided, each of which consists of two insertion holes 23. Also, insertion holes 23 are provided along the side sides of the protruding parts 22 on both ends. Similarly, when the interior material 20 is a partition plate, multiple sets of two insertion holes 23 may be provided.

[0016] FIG. 1D shows the support 30. The support 30 supports the interior material 20. The support 30 has a holding portion 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 portion 40 that supports the holding portion 50. The holding portion 50 protrudes from the mounting hole 13 opened in the bottom plate 11, leaving the base portion 40, 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. The first piece 31 and the second piece 32 can swing relative to each other with the apex position of the L shape as the axis c. The base portion 40 is formed by the one-side base portion 41 of the first piece 31 and the one-side base portion 41 of the second piece, and the holding portion 51 of the first piece 31 and the one-side holding portion 51 of the second piece 32 form the holding portion 50.

[0017] The material constituting the support 30 can be selected arbitrarily. 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. Examples of synthetic resins are polypropylene resin and acrylonitrile butadiene styrene resin (ABS resin). The support 30 includes a base portion 40 and a holding portion 50. The base portion 40 and the holding portion 50 of the support 30 are integrally molded by, for example, injection molding.

[0018] FIG. 2 is an enlarged perspective view of the support 30. In FIG. 2A, three-dimensional directions are indicated by x, y, and z. In this embodiment, the first piece 31 and the second piece 32 are members of the same shape and structure. Therefore, the first piece 31 will be described below as a representative. The first piece 31 has a single base portion 41 and a single holding portion 51, each of which is planar. The single base portion 41 and the single holding portion 51 are connected in an L-shape, and the single base portion 41 has a planar shape that spreads in the xy direction. The single holding portion 51 has a planar shape that spreads in the xz direction. The surface of the single holding portion 51 facing the y direction side, which is the opposite side of the single base portion 41, is the connecting side surface 52 (see FIG. 2A), and the back side is the back surface 53 (see FIG. 2B).

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

[0020] Additionally, one male connecting shaft 60 and one female connecting shaft 70 are provided on the connecting side surface 52 of the one holding portion 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 respective through holes 35, which are centered at r. The male key portions 61 are T-shaped with a tip that expands in the circumferential direction. The female key portions 71 have a recess q that receives the tip p of the male key portion 61 that protrudes in the circumferential direction from this T-shape.

[0021] The shaft portions 42 of the first piece 31 and the second piece 32 are arranged so that they are received in the bearing portions 43, and when the one-side holding portion 51 of the first piece 31 and the one-side holding portion 51 of the second piece 32 are brought face to face with the connecting side surface 52 of the first piece 31 and the connecting side surface 52 of the second piece 32, the male connecting shaft 60 and the female connecting shaft 70 are connected. The recess 54 on the connecting side surface 52 side is a gap into which a jig (not shown) is inserted to pull the male connecting shaft 60 and the female connecting shaft 70 apart.

[0022] Fig. 3 shows how the support 30 is assembled. In Fig. 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. When the two are fitted together, their axis lines c coincide, and the first piece 31 and the second piece 32 can swing relatively around the axis line c (Fig. 3B). When the connecting side surface 52 of the first piece 31 and the connecting side surface 52 of the second piece 31 are brought face to face, the male connecting shaft 60 and the female connecting shaft 70 overlap, and the male key portion 61 of one fits one-to-one into the female key portion 71 of the other, thereby connecting them (Fig. 3C).

[0023] 4, the method of assembling the interior of the storage container 1 using the support 30 will be described. After fitting the shaft portion 42 and the bearing portion 43 of the first piece 31 and the second piece 32, the base portions 41 of the first piece 31 and the second piece 32 are brought close to each other and inserted into the mounting hole 13 of the interior pad 10 from the top to the back (FIG. 4A). On the front side of the mounting hole 13, the interior material 20 is placed between the connecting side surface 52 of the first piece 31 and the connecting side surface 52 of the second piece 32 (FIG. 4B). After that, the male connecting shaft 60 and the 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 to connect the male connecting shaft 60 and the female connecting shaft 70. The interior material 20 is drawn toward the interior pad 10 in the process in which the connecting side surfaces 52 of the first piece 31 and the second piece 32 come close to each other, and is fixed in a state in which it stands up from the interior pad 10 (FIG. 4C).

[0024] According to the support 30 of this embodiment, the work of attaching the support 30 to the attachment hole 13 of the interior pad 10 does not require turning the interior pad 10 over, and can be performed from the top side of the interior pad 10. In other words, the interior material 20 is attached to the top side of the interior pad 10, which is the same as the side to which it is attached. Therefore, the attachment of the support 30 and the interior material 20 can be performed in a single operation, which is simple.

[0025] In this embodiment, the interior pad 10 is used, but if mounting holes 13 for mounting the support 30 to the storage container 1 can be formed, the interior pad 10 may be omitted. In this case, the mounting holes 13 are drilled in either or both of the wall plate materials of the bottom plate 2 and / or the side plate 3 of the storage container 1.

[0026] When drilling the mounting holes 13 in the storage container 1, there is no need to turn the storage container 1 upside down, and the mounting work of the support 30 can be performed from the storage space 4 side of the storage container 1. This is the same as the side where the mounting work of the interior material 20 is performed. In order to ensure a gap large enough for the one base part 41 to rotate, for example, the storage container 1 can be lifted slightly or the storage container 1 can be placed on a wire shelf, which is easier than turning it upside down. The fact that the work can be performed from the storage space 4 side of the storage container 1 is even more effective when the storage 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 with reference to FIG. First, in this embodiment, as shown in the right of FIG. 5A, the male key portion 61 has a T-shape with a tip p that spreads in the circumferential direction. The female key portion 71 has a recess q that receives the tip p of the T-shape male key portion 61. The tip p does not move away from the center r of the through hole 35, but remains at the radial position where the male key portion 61 is present. In contrast, as shown in the left of FIG. 5A, it is possible 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 present. However, in the case of the configuration shown in the left of FIG. 5A, when the male key portion 61' rides over the female key portion 71' to fit, there is a risk of friction and deformation, which leads to a decrease in the strength of both keys. According to the configuration shown in the right of FIG. 5A, the male key portion 61 has a T-shape and does not have a tip p that serves as a key in the riding direction, so there is little risk of friction and deformation when the male key portion 6 rides over the female key portion 7 to fit, and the strength can be kept almost constant.

[0028] In this embodiment, as shown in the right of FIG. 5B, slits S are provided on both sides of the base of the male key portion 61 in the direction away from the center r (FIG. 2 shows the slits S on both sides). By providing the slits S, the swing center sw of the male key portion 61 is shifted to the tip position of the slits S (the position farthest from the center r). On the other hand, when the slits S are not provided as shown in the left of FIG. 5B, the swing center position sw' of the male key portion 61' is directly below the male key portion 61'. When the force of the arrow F is applied by the female key portion, the male key portion 61' tilts from the swing center sw' toward the center r (see the broken line). The tilt toward the center r is in the direction away from the female key portion. When the slits S are provided as shown in the right of FIG. 5B, the swing center position sw of the male key portion 61 is farther from the center r than the position of the force of the arrow F applied by the female key portion. As a result, the male key portion 61 is inclined in the direction away from the pivot center sw toward the center r (see dashed line). Thus, with the configuration shown on the right side of Fig. 5B, the male key portion 61 is less likely to come off the female key portion 71, and this acts to strengthen the fit between the keys.

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

[0030] In this embodiment, if it is desired to further strengthen the connection between the male connecting shaft 60 and the female connecting shaft 70, a resin rivet (for example, Panlock (registered trademark) manufactured by Kunimori Chemical Industry Co., Ltd.) may be inserted into the central through-hole of the male connecting shaft 60 and the female connecting shaft 70 to secure them in place.

[0031] In this embodiment, the first piece 31 and the second piece 32 are members of the same shape and structure, but this may be changed. For example, only one or more male connecting shafts 60 may be provided on the first piece 31 side, and only one or more female connecting shafts 70 may be provided on the second piece 32 side, so as to correspond to the first piece 31. Also, 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 members of the same shape and structure, two types of parts management is required. [Explanation of symbols]
