Description

Technical Field

[0001] The present invention relates to a partition member used as an inner material of a storage container and a transport container.

Background Art

[0002] As a technique for partitioning the internal space of a storage container and a transport container into a plurality of small spaces, it is known to arrange an inner material called a so-called assembled partition inside the container. A plurality of slits are formed in the partition plate, and by meshing each slit with one another, the space is partitioned into lattice-shaped small spaces. In the case of an assembled partition, it is standard to design a dedicated slit interval for each product to be stored.

[0003] As a technique for flexibly partitioning the internal space, for example, partition members disclosed in Patent Documents 1 and 2 are known. A plurality of small-pitch slits cut from one side of the partition plate are formed in advance, and each slit is meshed with one another. By selecting and combining the slits, the internal space can be partitioned into a plurality of lattice-shaped small spaces of free sizes. Also, although it is not a technique for partitioning the internal space, there is a technique disclosed in Patent Document 3 as a technique for fixing a cushioning material. According to this technique, the regulation part is operated from the outside of the box body to fix or release the cushioning material inside the box body.

Summary of the Invention

Problems to be Solved by the Invention

[0005] According to the technologies disclosed in Patent Documents 1 and 2, slits cut from one side of a plate reduce the strength of the plate. Providing multiple slits in the plate beforehand to allow for changes in the partition plate pitch further reduces strength. Furthermore, the need for ears on the outside of the slits reduces the usable internal dimensions within the container. Additionally, because the structure involves interlocking the slits to cross the plate, force is applied to the slits each time the partition plate is reconfigured, causing cracks to spread from the slits. Moreover, the technology described in Patent Document 3, which involves attachment and detachment from the outside, is not suitable for partition members that require the combination of multiple partition materials.

[0006] This invention has been made in view of these conventional circumstances, and its purpose is to provide a partition member that can be easily and freely reconfigured and maintains its strength even after repeated separation and reconfiguration. [Means for solving the problem]

[0007] The partition member according to the present invention comprises a plurality of middle panels, each having a plug attached to a plurality of first connecting holes drilled along at least one edge, and a side panel or bottom panel, each having a socket that can be connected to the plug attached to a second connecting hole drilled according to the mounting pitch of the plurality of middle panels. A partition member that is installed in the internal space of a container to divide the internal space into a plurality of smaller spaces, The aforementioned plug is formed by attaching a pair of plug parts to the front and back of the middle panel, Each of the pair of plug parts has a gripping surface portion on which a pivoting key portion and a fixed key portion are symmetrically provided on the left and right sides, which can be fitted together with respect to the center line, and an insertion portion in which the bottom surface of the body portion along the center line is open and a pressing portion and a receiving portion are formed on the open edge, and the pair of plug parts are formed into the plug by connecting one pivoting key portion to the other fixed key portion within the connecting hole. on the other hand, The socket comprises a sleeve portion that fits the insertion portions of the pair of plug parts onto the outside, a claw that passes through the second connecting hole when the sleeve is inserted into the second connecting hole, and a flange portion that remains on the back side, the periphery of the second connecting hole being sandwiched by the claw and flange portion, and further inside the socket there is a spring portion having a slope, an operating portion at the tip of the spring portion, and a locking portion midway along the length of the operating portion, the operating portion being operable from below the flange portion through an opening provided on the inside of the flange portion, The plug and the socket are connected when, during the process of inserting the insertion portion of the plug into the sleeve portion of the socket, the retaining portion abuts against the inclined surface of the spring portion, causing the spring portion to elastically deform, and when the locking portion rides up from the lower side to the upper side of the receiving portion, the elastic deformation of the spring portion is released. The plug and the socket are separated by operating the operating part through an opening on the lower side of the flange portion, via an opening provided on the inside of the flange portion. [Effects of the Invention]

[0008] According to the present invention, when assembling the partition, the middle panel can be joined simply by pushing it toward the side panel or bottom panel. When disassembling the partition, the plug's operating part can be operated from the back of the side panel or bottom panel. When not in use, the middle panel, side panel, and bottom panel can be separated and stored compactly with the plug and socket still attached. Since the plug and socket can be stored attached to the board material, the partition can be reconfigured and changed while maintaining its strength even after repeated separation and reconfiguration.

[Figure 2] These are diagrams showing the partition members; Figure 2A shows the partition members disassembled, and Figure 2B shows the partition members assembled. [Figure 3]This diagram shows a plug; Figure 3A shows the back side of the plug part, and Figure 3B shows the front side. [Figure 4] This diagram shows a socket; Figure 4A is a perspective view, Figure 4B is a cross-sectional view, and Figure 4C shows how it connects to the plug. [Figure 5] This diagram shows the process of assembling the partition member 5. [Modes for carrying out the invention]

[0010] Hereinafter, embodiments of the partition member according to the present invention will be described with reference to the drawings. Figure 1 is a diagram showing the relationship between the storage container 1 and the partition member 5. In Figure 1, the internal space of the storage container 1 is divided into multiple partitioned spaces (three spaces in the figure) by the partition member 5. The partition member 5 is made of a fastener 10, a middle panel 6, side panels 7, and a bottom panel 8, and one more middle panel 6 is provided than the number of partitioned spaces. The side panels 7 are connected to both sides of the middle panel 6 via the fastener 10, and the bottom panel 8 is connected to the bottom of the middle panel 6 via the fastener 10.

[0011] The middle panel 6, side panels 7, and bottom panel 8 may be made of plastic corrugated cardboard, corrugated cardboard, thick paper, plywood, or cushioning material such as rubber or foam. The fasteners 10 are injection-molded resin parts. In this embodiment, plastic corrugated cardboard with a common thickness of 10 mm is used for all three panels: the middle panel 6, side panels 7, and bottom panel 8.

[0012] Figure 2 shows the partition member 5, and Figure 2A shows the partition member 5 in an exploded view. In Figure 2A, one or more (two in the figure) connection shapes R are formed along the edges of the middle panel 6, except for the top edge, along at least one of the opposing side edges and the bottom edge (in the figure, they are formed along all three edges). Each connection shape R has a perforated rectangular connecting hole R1 and protrusions R2, R2 cut out from the edges of the middle panel 6 on either side of the connecting hole R1.

[0013] A number of connection shapes S are formed on both side edges and the bottom edge. These are provided corresponding to the position where the middle panel 6 is to be installed and corresponding to the connection shape R of the middle panel 6. In FIG. 2A, for each of the side panel 7 and the bottom panel 8, when it is desired to form three partition spaces (see FIG. 1), the positions of the connection shape S used are enclosed by a broken line at four locations with a pitch T. Also, as shown in FIG. 2B, when forming four partition spaces, the positions of the connection shape S used are enclosed by a broken line at five locations with a pitch Q. Two connection shapes S are formed at each of the four positions with the pitch T. Two connection shapes S are also formed at each of the five positions with the pitch Q.

[0014] By forming two types of connection shapes S with the pitch T and the pitch Q on the side panel 7 and the bottom panel 8 and selectively attaching the socket 4, it is possible to freely change the position of the partition. On the other hand, the middle panel 6 with the plug 2 is common to the pitch T and the pitch Q. By manufacturing a large number of middle panels 6 with the plug 2 in advance, the degree of freedom in changing the position of the partition is improved.

[0015] The connection shape S has one rectangular connecting hole S1 and long holes S2, S2 into which convex portions R2, R2 provided on the side of the middle panel 6 are inserted with a width narrower than the end edge in the long side direction from the center of the short side of the connecting hole R1 (specifically, the thickness of the middle panel 6). The connecting hole S1 and the long holes S2, S2 are continuous, and the edge as a whole forms a closed curve in one circumference. The long holes S2, S2 are holes for inserting the convex portions R2, R2, and the vibration impact on the middle panel 6 is transmitted to the side of the long holes S2, S2 through the convex portions R2, R2 so as not to be directly transmitted to the side of the socket 4.

[0016] Both the connection shape R and the connection shape S are not slits cut from the side edges of the middle panel 6, or the side panel 7 and the bottom panel 8, but are formed by connecting holes R1 or connecting holes S1, S2 formed as closed curves provided in the plane of the middle panel 6, or the side panel 7 and the bottom panel 8, so they do not significantly reduce the strength of the middle panel 6, or the side panel 7 and the bottom panel 8.

[0017] The fixture 10 is composed of a plug 2 and a socket 4. The plug 2 is attached to the connection hole R1 from the front and back of the middle panel 6. Also, the socket 4 is attached from the back side (the opposite side of the middle panel 6) of the side panel 7 and the bottom panel 8. The plug 2 and the socket 4 are mutually engageable, and by assembling the middle panel 6, the side panel 7, and the bottom panel 8 with these attached, the partition member 5 can be obtained.

[0018] Figure 3 is a view showing the plug 2. The plug 2 is formed by fitting together a pair of identical plug parts 3. Figure 3A shows the back side of the plug part 3, and Figure 3B shows the front side. The plug part 3 includes a gripping surface part 31 and an insertion part 21. On the gripping surface part 31, a swing key part 33 and a fixed key part 37 are provided symmetrically on the left and right with the center line c in between. The swing key part 33 has a spring part 34, a frame part 35, and a hook body 36. The hook body 36 is provided at the tip of the spring part 34. The fixed key part 37 has a frame part 38 and a hook body 39. When the back surfaces (Figure 3A) of the two plug parts 3 face each other, the swing key part 33 on one side and the fixed key part 37 on the other side face each other. In this state, when they are further approximated, the swing key part 33 and the fixed key part 37 of each other are joined within the connection hole R1. The range where the frame part 35 and the frame part 38 are arranged is the same as the connection hole R1. When the plug parts 3 are fitted to each other from the front and back of the middle panel 6 across the connection hole R1, the movement of the plug 2 within the plane of the middle panel 6 is restricted by the frame part 35 and the frame part 38. At this time, the middle panel 6 is sandwiched by the gripping surface parts 31 on the front and back, and the insertion part 21 protrudes from the periphery of the middle panel 6.

[0019] The insertion part 21 has a body length along the center line c, and an opening 24 is provided in the bottom surface part 25. The edge of the opening 24 forms a pressing part 22 and a receiving part 23. When the pair of plug parts 3 are fitted together, the insertion parts 21 of both are inserted along the center line c into the sleeve part 41 of the socket 4 described later and are externally fitted.

[0020] Figure 4 shows the socket 4. Figure 4A is a perspective view, Figure 4B is a cross-sectional view, and Figure 4C shows the connection with the plug 2. The socket 4 comprises a sleeve portion 41 and a flange portion 42.

[0021] The circumference of the sleeve portion 41 is the same as the size of the connecting hole S1. When the sleeve portion 41 is inserted into the connecting hole S1, the flange portion 42 remains on one side of the connecting hole S1, and the claws 43 protrude on the opposite side, securing the sleeve portion 41 by sandwiching the periphery of the connecting hole S1 between the claws 43 and the flange portion 42. The claws 43 are formed on the upper edge of a bendable elastic portion 44 formed on a part of the sleeve portion 41, and act to prevent the claws 43 from getting in the way when the sleeve portion 41 passes through the connecting hole S1.

[0022] Inside the socket 4, there is a mountain-fold spring portion 46 having a slope inclined with respect to the center line c, and an operating portion 45 at the tip of the spring portion 46. Locking portions 47 are provided on both sides of the operating portion 45. When the slope of the spring portion 46 is pressed from above in the direction of the center line c, it deforms and moves the operating portion 45 at the tip in the direction of arrow A. The spring portion 46, operating portion 45, and locking portion 47 are provided on both sides of the center line c. The operating portion 45 can be operated from the opening 48 on the lower side of the flange portion 42.

[0023] Figure 4C illustrates the function of each part when the plug 2 is pushed into the socket 4. As the insertion portion 21 of the plug 2 is inserted into the sleeve portion 41, the retaining portion 22 first contacts the inclined surface of the spring portion 46, causing the spring portion 46 to elastically deform. When the socket 4 is pushed further in, the locking portion 47 moves in the direction of the in-plane direction of the flange portion 42 (arrow A) and disengages from the lower side of the receiving portion 23. Then, when the elastic deformation of the spring portion 46 is released, the locking portion 47 rides up onto the upper side of the receiving portion 23.

[0024] To remove the plug 2 from the socket 4, operate the operating part 45 through the opening 48 to elastically deform the spring part 46, move the locking part 47 in the direction of arrow A to detach it from the upper side of the receiving part 23, and then push up the bottom surface 25 of the insertion part 21 from below.

[0025] Figure 5 shows the process of assembling the partition member 5. The sleeve portion 41 of the socket 4 is inserted into the connecting hole S1 from the back surface of the side panel 7 and the bottom panel 8. The flange portion 42 is left on the back side, and the surface of the flange portion 42 is in contact with the back surface of the side panel 7 and the bottom panel 8. Meanwhile, the swing key portion 33 and the fixed key portion 37 of the plug part 3 are inserted into the connecting hole R1 of the middle panel 6 from the front and back to connect them. Then, the convex portion R2 is pushed into the elongated hole S2 and the insertion portion 21 is pushed into the sleeve portion 41 of the socket 4, causing the lock portion 47 to ride up on top of the receiving portion 23. As a result, the plug 2 and the socket 4 are connected.

[0026] According to this embodiment, when assembling the partition member 5, the middle panel 6, side panels 7, and bottom panel 8 can be joined simply by aligning the plug 2 and socket 4 and then pushing in the middle panel 6. Therefore, even partition members 5 with narrow pitch spacing of the middle panels 6 or partition members 5 that extend to the bottom, which are difficult to access during assembly, can be easily assembled.

[0027] Furthermore, when disassembling the partition member 5, the operating section 45 can be operated from the back surface of the side panel 7 and bottom panel 8, eliminating the need to reach into the joint between the middle panel 6 and the side panel 7 or bottom panel 8 to separate them, making the process simple.

[0028] After disassembling the partition member 5, the middle panel 6, side panels 7, and bottom panel 8 can be separated and stored compactly while the plugs 2 and sockets 4 remain attached. Since the plugs 2 and sockets 4 can be stored attached, the partition size and number of compartments can be freely changed while maintaining strength even after repeated separation and reassembly.

[0029] Furthermore, according to this embodiment, since the ear portion of the middle panel 6 does not protrude from the side panel 7, it is possible to provide a partition member 5 that can make maximum use of the effective dimensions inside the storage container 1.

[0030] In the above embodiment, the partition member 5 utilizes a middle panel 6, side panels 7, and a bottom panel 8. Since the middle panel 6 is fixed to both the side panels 7 and the bottom panel 8, it can be held stably while maintaining sufficient strength. On the other hand, since the partition member 5 is installed in the storage container 1, it is also possible to use only the middle panel 6 and side panels 7, or only the middle panel 6 and bottom panel 8. By combining the middle panel 6 with the side panels 7 or the bottom panel 8, partitions inside the storage container 1 can be easily formed.

[0031] In the above embodiment, the thickness of the middle panel 6, side panel 7, and bottom panel 8 is set to a common 10 mm. However, it is also possible to keep the thickness of the side panel 7 and bottom panel 8, which require strength, at 10 mm, while providing middle panel 6 in 10 mm and 5 mm thicknesses. In this case, the spacing between the opposing gripping surfaces 31 of the plug 2 can be set for 5 mm thickness and 10 mm thickness, and the size of the insertion portion 21 can be the same. In this way, middle panel 6 with a thickness of 10 mm and a thickness of 5 mm can be used in combination without changing the side panel 7, bottom panel 8, or the sockets 4 attached to each panel.
