Description

[Technical Field]

[0001] The present invention relates to a partition member that divides the internal space of a box-shaped vessel such as a container, and to a storage vessel using the partition member. [Background technology]

[0002] A technology known as a "combined partition" is known for dividing the interior space of storage containers and other such vessels into multiple small spaces. Multiple cutouts are formed in the partition plate, and by interlocking these cutouts, the space is divided into a grid of small spaces. In a combined partition, it is standard practice to design the cutout spacing specifically for each product to be stored.

[0003] As a technique for dividing a partition space more flexibly in a combined partition, for example, the partition members disclosed in Patent Documents 1 and 2 are known. A plurality of small-pitch notches are formed in advance in the partition plate, and each notch is interlocked with another. By selecting and combining the notches, the internal space can be divided into a plurality of lattice-like small spaces of any size. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2006-516515 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-179071 Summary of the Invention [Problem to be solved by the invention]

[0005] With conventional partitions, it is standard to design a dedicated partition for each product to be stored, so even partitions with a common grid may be loose depending on the product shape. Also, unused partitions (idle partitions) require storage space, and if the partitions are fixed with metal rivets or the like, they can lead to damage to the products.

[0006] Furthermore, according to the technologies disclosed in Patent Documents 1 and 2, if the pitch of the multiple notches provided in the partition plate is made too close in order to increase the degree of freedom in the partition spacing, the strength of the interlocking parts formed by these notches will be significantly reduced, and there will be restrictions on the partition spacing. Also, the technology is based on the premise that the partitions will be arranged in a lattice pattern, and diagonal partitions are not possible.

[0007] The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a partition member that divides the internal space of a storage container and whose position can be freely adjusted. [Means for solving the problem]

[0008] The partition member according to the present invention is a partition member that divides an internal space of a storage container surrounded by side plates into a plurality of small spaces by means of partition plates, The partition member is a groove part having a rectangular parallelepiped multi-slot part protruding in a direction perpendicular to the flange part extending two-dimensionally, and having a plurality of slot grooves arranged at equal intervals on the front side thereof, each having a length in a direction perpendicular to the direction, and a pair of hook parts protruding from the flange part in the direction; a partition joint part in which a pair of wing parts, each having a key base part and a receiving base part that can be fitted together, are connected to a central main body part by a hinge part so that they can face each other, and the main body part is provided with a shaft part that is inserted into one of the slot grooves; The groove part has a flange portion and a hook portion that protrude from an insertion hole provided in the side plate or the partition plate, and the hook portion can engage with a side surface of the insertion hole; and The partition joint part is characterized in that it can be clamped between the pair of wing portions on both sides of the end portion of the partition plate and into a connecting hole provided at the end portion, allowing the key base portion and the receiving base portion to be fitted together in the connecting hole. [Effects of the Invention]

[0009] According to the partition member fastener and partition member of the present invention, when the partition member is attached to a box-shaped container, it is possible to reduce the dead space that occurs between the inner surface of the box-shaped container and the partition member. [Brief explanation of the drawings]

[Figure 2] FIG. 10 is a diagram illustrating a groove part. [Figure 3] 10A and 10B are diagrams illustrating a partition joint part and a partition plate. [Figure 4] 10A and 10B are diagrams illustrating the connection between the groove part and the partition joint part. DETAILED DESCRIPTION OF THE INVENTION

[0011] A partition member embodying the present invention will now be described with reference to the drawings. In FIG. 1, storage container 1 is made of a resin plate, cardboard, or the like (hereinafter referred to as plate material, etc.). The internal space surrounded by the side plates 2 of storage container 1 in a rectangular shape is divided into a plurality of small spaces by a plurality of partition members 10. Partition members 10 have groove parts 20 and partition joint parts 40, and are also partitioned using partition plates 60. Groove parts 20 and partition joint parts 40 are resin parts, and partition plates 60 are plate material, etc. Note that side plates 2 of storage container 1 are provided with predetermined slits as described below.

[0012] FIG. 2 is a diagram illustrating the groove part 20. The groove part 20 is integrally molded from resin and has a flange portion 21, a multiple slot portion 22, and a pair of hook portions 23a and 23b. FIG. 2A is a perspective view of the groove part 20. The directions in which the flange portion 21 extends two-dimensionally are defined as the x direction (horizontal direction) and the y direction (vertical direction), and the direction perpendicular to these directions is defined as the z direction. In the drawing, the length direction of the flange portion 21 is defined as the x direction. The multiple slot portion 22 has its length direction in the x direction and protrudes from the flange portion 21 in the z direction. The multiple slot portion 22 has a rectangular parallelepiped shape. The pair of hook portions 23a and 23b protrude from both ends of the multiple slot portion 22 in the z direction from the flange portion 21 (see FIG. 2B).

[0013] On the front side of the rectangular parallelepiped multiple slot section 22 protruding in the z direction, multiple slot grooves 24, each having a length in the y direction, are arranged at equal intervals in the x direction (8 mm pitch in this example). Each slot groove 24 is circular in a cross section perpendicular to the y direction and has a fan-shaped opening 26 in the z direction via a neck portion 25. Each slot groove 24 is sandwiched between a fixed bottom 27 in the y direction and a movable lid 28. The fixed bottom 27 is provided with multiple radial angle grooves 27a (three in this example, one on each side of the central z-direction angle groove 27a). The angle grooves 27a are discretely provided at 22.5-degree intervals relative to the central axis of each slot groove 24 in the y direction. Movable lids 28 are connected to each other for a predetermined number of slot grooves 24 (three in this example). The movable lids 28 have lid locks 29 for locking the movable lids 28 in a closed position. The cover key portion 29 is inserted into a keyhole portion 30 provided between adjacent slot grooves and the sector-shaped opening 26, and the claw portion 29a at the tip can be engaged with the hook portion 31.

[0014] The hook portions 23a, 23b have a U-shaped spring portion 32 protruding in the z-direction from the flange portion 21, and a claw portion 36 having two clamping surfaces 34, 35 of different heights with intervals P and Q between them and sandwiching a step portion 33 relative to the surface of the flange portion 21.

[0015] Returning to Figure 1, a predetermined slit is formed in the side plate 2 of the storage container 1. The predetermined slit is a process for forming a rectangular insertion hole 3 in the side plate 2, and is formed by cutting either the upper long side 4 or the lower long side 5 of the insertion hole 3 in a bendable state (in this example, long side 4 is bendable), while cutting the other three sides. When the groove part 20 is inserted from the outside of the side plate 2, the flange portion 21 remains on the outside of the side plate 2, and the multiple slot portion 22 and the hook portions 23a, 23b protrude inside the side plate 2.

[0016] The length of the pair of short sides 6, 7 of the insertion hole 3 opens to correspond to the width in the y direction of the multiple slot portion 22. If the difference between the two is small, rattling of the multiple slot portion 22 in the y direction can be suppressed.

[0017] 2B, the length of the opposing long sides 4, 5 of the insertion hole 3 corresponds to the distance P between the step portions 33 of the pair of hook portions 23a, 23b or the distance Q between the spring portions 32. Whether the length of the opposing long sides 4, 5 of the insertion hole 3 corresponds to the distance P or the distance Q is determined depending on the thickness of the plate material or the like that forms the storage container 1. FIGS. 2C and 2D show cross sections when the hook portions 23a, 23b are engaged with the side surfaces of the insertion hole 3 provided in the side plate 2 of the storage container 1.

[0018] In Figure 2C, when the thickness of the plate material of the side plate 2 corresponds to the distance k1 between the surface of the flange portion 21 and the clamping surface 34, the length of the long sides 4 and 5 of the insertion hole 3 is set to P, so that the side plate 2 of the storage container 1 is sandwiched between the flange portion 21 and the clamping surface 34.

[0019] In Figure 2D, when the thickness of the plate material of the side plate 2 corresponds to the distance k2 between the surface of the flange portion 21 and the clamping surface 35, the length of the long sides 4 and 5 of the insertion hole is set to Q, so that the side plate 2 of the storage container 1 is sandwiched between the flange portion 21 and the clamping surface 35.

[0020] FIG. 3 is a diagram illustrating a partition joint part 40 and a partition plate 60. In FIG. 3A, the partition joint part 40 has a pair of wings 43, 44 attached to both sides of a main body 41 via a hinge part 42, and a cylindrical shaft part 46 attached to an arm part 45. The arm part 45 has protrusions 51 on the top and bottom (see FIG. 3C). One of the wings 43 has a key base part 47, and the other wing part 44 has a receiving part 50. A through hole th is opened in the center of the key base part 47 and the receiving part 50. Here, the diameter of the key base part 47 is taken as diameter t. A flange part 48 with a diameter s is provided at the base side of the key base part 47. The diameter of the receiving part 50 is equal to the diameter s of the flange part 48.

[0021] One of the wings 43, 44 can be positioned to face each other by the hinge portion 42, and when they face each other, the key base portion 47 and the receiving portion 50 fit together. Specifically, the claw portion 49 provided on the key base portion 47 fits into the hook portion 52 (see FIG. 3C) of the receiving portion 50, thereby achieving the fitting. When the key base portion 47 and the receiving portion 50 are fitted together, the through holes th of both the key base portion 47 and the receiving portion 50 overlap with each other, thereby forming a through hole TH that passes through both the wing portion 43 and the wing portion 44. The through hole TH is provided so that a resin rivet (for example, Panlock (registered trademark) manufactured by Kunimori Chemical Co., Ltd.) can be inserted for reinforcement.

[0022] The pair of wings 43, 44 are each provided with two clamping surfaces 53, 54. The clamping surfaces 53, 54 face each other when the pair of wings 43, 44 face each other. One clamping surface 53 is the top surface of the cradle portion 50. The other clamping surface 54 is provided on the flange portion 48.

[0023] Partition plate 60 is a rectangular plate or the like, and as shown in Fig. 3B, connecting holes 61 are drilled at both ends or one end, into which key base portion 47 and receiving base portion 50 are inserted. In Fig. 3C, the end of partition plate 60 is sandwiched between a pair of wings 43, 44. Then, as shown in Fig. 3D, key base portion 47 and receiving base portion 50 are inserted into connecting holes 61, and claw portion 49 is fitted into hook portion 52, thereby connecting partition joint part 40 and partition plate 60.

[0024] The size of the connecting hole 61 is determined according to the thickness of the partition plate 60. Figures 3E and 3F show cross sections of the partition joint part 40 and the partition plate 60 when connected in the connecting hole 61.

[0025] In FIG. 3E, when the thickness of the partition plate 60 corresponds to the distance k3 between the clamping surfaces 53 and 54 when they are facing each other, the diameter of the connecting hole is set to t, so that the partition plate 60 is sandwiched between the clamping surfaces 53 and 54.

[0026] In FIG. 3F, when the thickness of the partition plate 60 corresponds to the distance k4 between the wing portions 43 and 44 when they face each other, the diameter of the connecting hole 61 is set to s, so that the partition plate 60 is sandwiched between the wing portions 43 and 44.

[0027] Referring to Figure 4, the connection between the groove part 20 and the partition joint part 40 will be described. The shaft part 46 is inserted into the slot groove 24. The neck part 25 makes it difficult for the shaft part 46 to come out of the slot groove 24 in the z direction. The arm part 45 is located inside the fan-shaped opening 26, and the protrusion 51 on the underside of the arm part 45 is inserted into one of the angle grooves 27a. As a result, the partition joint part 40 can be angled in the xz plane relative to the groove part 20. When the movable lid 28 is closed, the lid key part 29 is inserted into the keyhole part, and the claw part 29a engages with the hook part 31. This makes it difficult for the shaft part 46 to come out in the y direction.

[0028] Returning to FIG. 1 , a storage container 1 incorporating the partition member 10 of this embodiment will now be described. Insertion holes 3 are formed in the storage container 1 by a predetermined slit processing. A groove part 20 is attached to the insertion hole 3. Partition joint parts 40 are attached to both ends or one side of a partition plate 60 of various lengths and shapes. Using the groove part 20 as a base, the shaft 46 of the partition joint part 40 is inserted into the corresponding slot groove 24. By connecting two slot grooves 24 at appropriate positions with a partition plate 60 having partition joint parts 40 attached to both ends, it is possible to divide the internal space diagonally. The insertion holes 3 may be formed in the partition plate 60, which allows for the creation of partitions in multiple directions and of any size.

[0029] According to this embodiment, it is possible to arrange the partitions to suit the products to be stored. In this embodiment, the arrangement pitch of the slot grooves 24 is 8 mm, but if partition grooves are provided in the plate material or the like at such a pitch as in the prior art, there is a possibility that the strength will be reduced or that weak parts will be damaged. In this embodiment, it is possible to arrange the partitions to suit the products to be stored without providing partition grooves in the plate material or the like at such a pitch, so that the cost of transporting products can be reduced due to high storage efficiency.

[0030] Furthermore, both the groove parts 20 and the partition joint parts 40 are made of resin and do not contain metal, minimizing damage to the stored products. Furthermore, compared to designing a dedicated set of partitions for each storage product to avoid fine-pitch partition grooves, this embodiment eliminates the need for a dedicated set of partitions for each storage product, making it possible to reduce the storage space for excess components. Furthermore, in this embodiment, even if the partition member 10 is damaged, it can be easily repaired by simply replacing or exchanging it, and since it is a single component, it is easy to recycle.
