[First embodiment]
1 shows an enclosure formed by connecting four cardboard partitions 101 to 104 using a partition connector 10 according to the first embodiment of the invention. This enclosure can be used to ensure privacy in an evacuation shelter or as a screen for those working from home.

Figure 2 is an exploded view of the partition connector 10 of the first embodiment. Referring to Figure 2, the partition connector 10 is formed by punching out a sheet of corrugated cardboard, and includes a first inner panel 11 disposed on the inside of one of the partitions (e.g., partition 102), a first bridge portion 12 connected to the side edge of the first inner panel 11 (the lower side edge in Figure 2) via a fold line L1, and a first outer panel 13 connected to the first bridge portion 12 via a fold line L2.

The second inner plate 14 is connected to the side edge of the first inner plate 11 perpendicular to the fold line L1 via three fold lines L3, L4, and L5 that are spaced apart and parallel to each other. The second inner plate 14 is connected to a protrusion 14a that protrudes from the center of the fold line L5 toward the first inner plate 11. A pair of engagement pieces 14b that protrude laterally are connected to the tip of the protrusion 14a via a fold line 14c. The protrusions 14a and engagement pieces 14b are formed by cutting a part of the first inner plate 11 at the cut line 14d.

The second bridge section 15 is connected to the lower edge of the second inner panel 14 in FIG. 2 via a fold line L6 that extends along an extension of the fold line L1. The second outer panel 16 is connected to the lower edge of the second bridge section 15 in FIG. 2 via a fold line L7 that extends along an extension of the fold line L2. The second outer panel 16 is connected to the first outer panel 13 via a fold line L8 that extends along an extension of the fold line L4.

The first outer panel 13 has a rectangular cutout hole 13a into which the protrusion 14a is inserted during assembly. The cutout hole 13a is formed to extend slightly beyond the fold line L8 toward the second outer panel 16.

In addition, in the center of the partition connector 10 in its unfolded state, an auxiliary connector 17 is provided that is cut and hollowed out along the cut line 17a. The auxiliary connector 17 is to be used separately from the partition connector 10. The auxiliary connector 17 comprises a first auxiliary plate 17b, a first auxiliary bridge portion 17c that is connected to the lower edge of the first auxiliary plate 17b in FIG. 2 via a fold line that extends along the extension of the fold lines L1 and L6, and a second auxiliary plate 17d that is connected to the lower edge of the first auxiliary bridge portion 17c in FIG. 2 via a fold line that extends along the extension of the fold lines L2 and L7.

The third auxiliary plate 17e is provided on the right edge of the first auxiliary plate 17b in FIG. 2 via a fold line that extends along the extension of the fold lines L4 and L8. The second auxiliary bridge portion 17f is provided on the lower edge of the third auxiliary plate 17e in FIG. 2 via a fold line that extends along the extension of the fold lines L1 and L6. The fourth auxiliary plate 17g is provided on the lower edge of the second auxiliary bridge portion 17f in FIG. 2 via fold lines L2 and L7. The second auxiliary plate 17d is connected to the left edge of the fourth auxiliary plate 17g in FIG. 2 via a fold line that extends along the extension of the fold lines L4 and L8.

Next, a method of assembling the partition connector 10 will be described. With reference to FIG. 3, when assembling the partition connector 10, first, the auxiliary connector 17 is removed along the cut line 17a, and then the first bridge portion 12 and the second bridge portion 15 are folded perpendicularly to the first outer panel 13 and the second outer panel 16 along the fold lines L2 and L7. Next, the first inner panel 11 and the second inner panel 14 are folded perpendicularly to the first bridge portion 12 and the second bridge portion 15 along the fold lines L1 and L6, resulting in the state shown in FIG. 3. At this time, the width of the first bridge portion 12 and the second bridge portion 15 is set so that the distance between the first inner panel 11 and the second inner panel 14 and the first outer panel 13 and the second outer panel 16 is equal to or greater than the thickness of the partitions 101 to 104.

Next, referring to FIG. 4, the first inner plate 11 is bent so that the angle it forms with the second inner plate 14 is a right angle. At this time, the protruding piece 14a maintains a parallel state with the second inner plate 14 without bending at a right angle together with the first inner plate 11 due to the cut line 14d, and by bending the engaging piece 14b via the fold line 14c, it is inserted into the cutout hole 13a of the first outer plate 13, which is bent at a right angle together with the first inner plate 11.

The engagement piece 14b connected to the protrusion 14a inserted into the cutout hole 13a acts on the protrusion 14a by a self-restoring force that causes it to return to the same plane as the protrusion 14a, preventing the protrusion 14a from slipping out of the cutout hole 13a. Note that in the first embodiment, adjacent partitions 101 to 104 are connected to each other at an angle of 90 degrees by the partition connector 10, but the angle of the partition connector 10 is not limited to 90 degrees, and the angle can be adjusted from 180 degrees, at which the protrusion 14a remains inserted into the cutout hole 13a, to 80 degrees, which is the bending limit of the fold lines L3, L4, and L5 of the first inner panel 11 and the second inner panel 14.

Next, referring to FIG. 5, a corner of partition 101 is inserted into the space surrounded by second inner plate 14, second bridge section 15, and second outer plate 16, and a corner of partition 102 is inserted into the space surrounded by first inner plate 11, first bridge section 12, and first outer plate 13, so that partitions 101 and 102 are connected at a 90 degree angle.

Next, referring to Figure 6, a method of using the auxiliary connector 17 will be described. The auxiliary connector 17 is used when connecting another enclosure 100', which is made up of four adjacent partitions 103', 104', to the enclosure 100, which is made up of partitions 101-104.

When the auxiliary connector 17 is removed from the partition connector 10, the first auxiliary bridge portion 17c and the second auxiliary bridge portion 17f are folded at right angles to the second auxiliary plate 17d and the fourth auxiliary plate 17g along fold lines that extend on the extensions of the fold lines L2 and L7. Then, the first auxiliary plate 17b and the third auxiliary plate 17e are folded at right angles to the first auxiliary bridge portion 17c and the second auxiliary bridge portion 17f along fold lines that extend on the extensions of the fold lines L1 and L6 so that the first auxiliary plate 17b and the third auxiliary plate 17e face the second auxiliary plate 17d and the fourth auxiliary plate 17g with a gap of the thickness of the partitions 101 to 104 between them.

Next, the first auxiliary plate 17b and the second auxiliary plate 17d are folded perpendicularly to the third auxiliary plate 17e and the fourth auxiliary plate 17g along fold lines that extend along the extensions of fold lines L4 and L8, completing the auxiliary connector 17.

The completed auxiliary connector 17 connects the partitions 101-104, 103', 104' across the adjacent enclosures 100, 100'. Specifically, the partition 102 is inserted between the third auxiliary plate 17e and the fourth auxiliary plate 17g, and the partition 103' of the adjacent enclosure 100' is inserted between the first auxiliary plate 17b and the second auxiliary plate 17d. The auxiliary connector 17 is fitted into the portion of the partition 102, 103' exposed from the opening created by removing the auxiliary connectors 17, 17' of the partition connectors 10, 10'.

In the same manner, the partition 101 and the partition 104' of the adjacent enclosure 100' are connected by the auxiliary connector 17' that has been removed from the partition connector 10' that connects the partitions 103' and 104' of the adjacent enclosure 100', as shown in Figure 7.

As in the first embodiment, the auxiliary connector 17 is provided by forming a cut line 17a to surround the intersection of the extensions of the fold lines L1, L2, L6, and L7 and the extensions of the fold lines L4 and L8 in the developed view of the screen connector 10 as shown in Figure 2. This allows all of the fold lines of the auxiliary connector 17 to be formed simultaneously with the fold lines L1, L2, L6, L7, L4, and L8 of the screen connector 10, eliminating the need to form fold lines specifically for the auxiliary connector 17 and making it easy to manufacture the auxiliary connector 17.

In this embodiment, the auxiliary connector has been described as having cuts in all of the first, second, third, and fourth side plates, and being formed by cutting them apart, but it is sufficient that the cuts are provided in at least one pair of the first and second side plates, or the third and fourth side plates.

According to the first embodiment of the screen connector 10, the engagement piece 14b provided on the protruding piece 14a protrudes toward the outer surface of the first outer panel 13, and the maximum opening angle of the screen connector 10, which is represented by the angle between the first inner panel 11 and the second inner panel 14, is limited to 180 degrees. Also, for example, referring to FIG. 5, even if the screen 102 tries to open beyond 180 degrees relative to the screen 101, the protruding piece 14a protruding from the cutout hole 13a toward the outer surface of the first outer panel 13 acts to prevent the screen 102 from moving. This makes it easier to connect the screens 101 to 104 using the screen connector 10, and makes it easier to assemble the enclosure 100, compared to when the maximum opening angle of the screen connector 10 opens beyond 180 degrees or when the angle between adjacent screens opens beyond 180 degrees.

[Second embodiment]
8 is an exploded view of a partition connector 20 according to a second embodiment of the invention. The partition connector 20 according to the second embodiment is configured in the same manner as the first embodiment, except that the projections and cutout holes for preventing the connected partitions 101 to 104 from opening at an angle of more than 180 degrees are different from those in the first embodiment. These components are denoted by the same reference numerals and will not be described.

As shown in the development view of Figure 8, the second embodiment of the partition connector 20 has a first tapered trapezoidal projection 31 that projects from the fold line L3 of the first inner panel 11 toward the second inner panel 14, a second tapered trapezoidal projection 32 that projects from the second inner panel 14 toward the first inner panel 11, and a third tapered trapezoidal projection 33 that projects from the first inner panel 11 toward the second inner panel 14.

The first protrusion 31, the second protrusion 32, and the third protrusion 33 are formed between the first inner plate 11 and the second inner plate 14 by a cut line 30 that is cut in a zigzag pattern from the center of the fold line L3.

The second outer panel 16 has a first cutout hole 41 into which the first protrusion 31 is inserted when the screen connector 20 is assembled, as in the first embodiment. The first cutout hole 41 has a first retaining piece 41a, which is provided via a fold line and whose tip edge on the first outer panel 13 side can swing freely with the edge on the second outer panel 16 side as a fulcrum. As shown in FIG. 9, when the screen connector 20 is assembled, the first protrusion 31 is inserted into the first cutout hole 41, climbing over the first retaining piece 41a, and the first retaining piece 41a prevents the first protrusion 31 from slipping out of the first cutout hole 41.

The first outer panel 13 has a second cutout hole 42 into which the second protrusion 32 is inserted when the screen connector 20 is assembled, as in the first embodiment. The second cutout hole 42 has a second retaining piece 42a, which is provided via a fold line and whose tip edge on the second outer panel 16 side can swing freely with the edge on the first outer panel 13 side as a fulcrum. As shown in FIG. 9, when the screen connector 20 is assembled, the second protrusion 32 climbs over the second retaining piece 42a and is inserted into the second cutout hole 42, and the second retaining piece 42a prevents the second protrusion 32 from slipping out of the second cutout hole 42.

The second outer panel 16 has a third cutout hole 43 into which the third protrusion 33 is inserted when the screen connector 20 is assembled, as in the first embodiment. The third cutout hole 43 has a third retaining piece 43a provided via a fold line, the third retaining piece 43a being able to swing at its leading edge on the first outer panel 13 side, with the edge on the second outer panel 16 side as a fulcrum. As shown in FIG. 9, when the screen connector 20 is assembled, the third protrusion 33 is inserted into the third cutout hole 43, climbing over the third retaining piece 43a, and the third retaining piece 43a prevents the third protrusion 33 from slipping out of the third cutout hole 43.

According to the second embodiment of the screen connector 20, as in the first embodiment, the second protrusion 32 protrudes toward the outer surface of the first outer panel 13, and the first protrusion 31 and the third protrusion 33 protrude toward the outer surface of the second outer panel 16, limiting the maximum opening angle of the screen connector 10, which is represented by the angle between the first inner panel 11 and the second inner panel 14, to 180 degrees. Even if adjacent screens attempt to open beyond 180 degrees, the second protrusion 32 protruding from the second cutout hole 42 toward the outer surface of the first outer panel 13, and the first protrusion 31 and the third protrusion 33 protruding from the first cutout hole 41 and the second cutout hole 43 toward the outer surface of the second outer panel 16, respectively, act to prevent the screen from moving. This makes it easier to connect the partitions 101-104 using the partition connector 20, and easier to assemble the enclosure 100, compared to when the maximum opening angle of the partition connector 20 exceeds 180 degrees, or when the angle between adjacent partitions exceeds 180 degrees, as in the first embodiment.

In addition, in the second embodiment of the screen connector 20, the first protrusion 31 and the third protrusion 33 also protrude from the outer surface of the second outer panel 16, so the maximum opening angle can be more firmly limited compared to the first embodiment. In addition, the first protrusion 31 and the third protrusion 33 are spaced apart from each other, so the two protrusions can more balancedly limit the screen from opening beyond 180 degrees.

[Third embodiment]
10 is an exploded view of a partition connector 50 according to a third embodiment of the invention. The partition connector 50 according to the third embodiment is designed to allow partitions to be easily disconnected from each other so that one of the partitions can be used as an openable and closable door.

Referring to FIG. 10, the partition connector 50 comprises a first side panel 51, a first connection portion 52 connected to the lower edge of the first side panel 51 in FIG. 10 via a fold line L11, and a second side panel 53 connected to the lower edge of the first connection portion 52 in FIG. 10 via a fold line L12.

10, the first door support plate 61 is connected to the lower part of the right edge of the first side plate 51 via a fold line L13. A first extension is provided to the right of the fold line L13 of the first side plate 51, and a tapered fitting protrusion 51b is provided, which is formed by a pair of cut lines 51a that are formed so that the distance between them gradually narrows toward the right edge. A part of the upper edge of the first door support plate 61 in FIG. 10 is formed by a cut line 61a that extends from the right edge of the first side plate 51 in FIG. 10 to the left side of FIG. 10. The cut line 61a extends to the base end position of the fitting protrusion 51b in the left-right direction of FIG. 10. The fold line L13 is also located at the same location as the base end of the fitting protrusion 51b in the left-right direction of FIG. 10.

The second connection part 62 is connected to the lower edge of the first door support plate 61 in FIG. 10 via a fold line L14 that extends on an extension of the fold line L11. The second door support plate 63 is connected to the lower edge of the second connection part 62 in FIG. 10 via a fold line L15 that extends on an extension of the fold line L12. In addition, a second extension part is provided to the right of the fold line L16 in FIG. 10 of the second side plate 53, and a fitting protrusion 53b is provided that is gradually wider toward the tip formed by a pair of cut lines 53a that are formed so that the distance between them gradually increases toward the right edge.

A portion of the lower edge of the second door support plate 63 in FIG. 10 is formed by a cut line 63a that extends from the right edge of the second side plate 53 in FIG. 10 toward the left side of FIG. 10. The cut line 63a extends to the position of the base end of the fitting protrusion 53b in the left-right direction of FIG. 10. The left edge (base end edge) of the second door support plate 63 in FIG. 10 is connected to the second door support plate 63 via a fold line L16. The fold line L16 is also located at the same location as the base end of the fitting protrusion 53b in the left-right direction of FIG. 10.

Next, a method for assembling the connection aid 50 of the third embodiment will be described. Referring to FIG. 11, first, the first connection portion 52 and the second connection portion 62 are folded perpendicularly to the second side plate 53 and the second door support plate 63 along the fold lines L12 and L15. Then, the first side plate 51 and the first door support plate 61 are folded perpendicularly to the first connection portion 52 and the second connection portion 62 along the fold lines L11 and L14, so that the first side plate 51 and the first door support plate 61 face the second side plate 53 and the second door support plate 63.

Then, the fitting protrusion 53b is pushed toward the fitting protrusion 51b, so that the wide tip of the fitting protrusion 53b protrudes toward the outer surface of the first side plate 51. This causes the fitting protrusion 53b to be sandwiched between the first side plate 51 and the fitting protrusion 51b, and the state shown in FIG. 11 can be maintained.

When connecting the partitions 101 and 104, as shown in FIG. 12, the partition 104 is fitted between the first side plate 51 and the second side plate 53. Then, the first door support plate 61 and the second door support plate 63 are folded at right angles to the first side plate 51 and the second side plate 53 via fold lines L13 and L16, and the partition 101 is fitted between the first door support plate 61 and the second door support plate 63. This connects the two partitions 101 and 104.

Referring to FIG. 13, the first door support plate 61 and the second door support plate 63 are formed smaller than the first side plate 51 and the second side plate 53, so that the partition 101 can be relatively easily removed from between the first door support plate 61 and the second door support plate 63, and the partition 101 can be used as a door for opening and closing the enclosure 100.

In all of the embodiments described here, the first and second side panels, the third and fourth side panels, the first and second auxiliary panels, the third and fourth auxiliary panels, and the first and second door support sections are indirectly connected via bridges or connecting sections, but may also be directly connected via folds.

In this embodiment, the pair of cut lines 53a extend to the end of the second extending portion 53c, and a portion of the bent cut coincides with one side of the second extending portion 53c. However, the present invention is not limited to this, and the cut may be, for example, U-shaped, C-shaped, V-shaped, or U-shaped as long as the entire cut is inside the second extending portion 53c.
