It is a long hole for coupling formed through at equal intervals along the crease line 3 d on the left side of the plate surface 2. These long holes for coupling are denoted by reference numeral 15 when the position is not particularly specified.

  Reference numerals 15a ', 15b', 15c 'denote positions corresponding to the penetrating positions of the coupling elongated holes 15a to 15c (positions translated) on the plate surface of the reinforcing peripheral edge 4a on the upper side of the plate surface 2, respectively.

These long holes for coupling are indicated by reference numeral 15 'unless the position is particularly specified.

  When the reinforcing peripheral edge 4 is erected, the coupling long hole 15 is located at a corner along the crease line 3a. Therefore, in the developed state of FIG. 1, the width t ′ of the opening is the coupling long hole. It is formed about twice as wide as 15 '.

  These coupling long holes 15, 15 ′ join two or more standing peripheral edge portions 4 ′ of the corrugated cardboard partition 1 (see FIG. 7), and the coupling long holes 15, 15 ′ of the adjacent partition 1 are joined together. The long holes 15 and 15 'are joined to each other so as to be aligned with each other, and the holding slits 12 of the connecting piece 9a are inserted into the connecting long holes 15 and 15', respectively. A plurality of cardboard partitions 1 can be connected by sandwiching the cardboard surfaces of both raised peripheral edges 4 'through the coupling elongated holes 15, 15' with the slits 12 for use. ing.

  The cardboard partition 1 of the present invention can be easily formed by punching one rectangular cardboard plate as shown in FIG. In this case, the crease lines 3a to 3d, the crease lines 5a to 5d, and the crease lines 5e to 5h in FIG. 1 are formed at the same time as the above punching by forming recesses on the cardboard surface. 14 can be formed simultaneously with the above punching.

  Since the cardboard partition of the present invention is configured as described above, the assembling method will be described below.

  First, all the connecting piece parts 9 are separated from the unfolded cardboard partition 1. In this case, each coupling piece component 9 is connected to the plate surface 2 (reinforcing peripheral edge 4b or 4d) by the perforation 10, so that it can be easily separated along the perforation 10. In this case, the coupling piece parts 9 are separated along the perforation 14. Next, the coupling piece 9a and the blinding lock piece 9b of the separated coupling piece part 9 are separated. Also in this case, since the coupling piece 9a and the blindfold locking piece 9b are connected by the perforation 11, they can be easily separated.

  Next, the cardboard partition 1 is assembled. First, the reinforcing peripheral portions 4a to 4d are erected in the same direction at an angle of 90 degrees along the crease lines 3a to 3d, and the reinforcing corner pieces 6a, 6b, 6c and 6d of the reinforcing peripheral portions 4a and 4c are erected. The reinforcing peripheral portions 4a and 4c are bent inward at an angle of 90 degrees to be along the crease lines 3b and 3d (see FIGS. 3A and 3B).

  Next, the reinforcing peripheral edges 4b and 4d are erected at an angle of 90 degrees, and the reinforcing corner pieces 6e, 6f, 6g, and 6h of the reinforcing peripheral edges 4b and 4d are bent downward, respectively. Polymerization is performed (see FIG. 3C). By doing so, the engaging protrusions 7 of the reinforcing corner portions 6a to 6d are fitted in the corresponding engaging holes 7 'and bent, and the engaging protrusions of the reinforcing corner pieces 6e to 6h are bent. 8 fit into the corresponding engagement holes 8 ', thereby connecting the corner portions of the reinforcing peripheral portions 4a to 4d. As a result, as shown in FIG. 4, the standing peripheral edge 4 ′ in the standing state can be formed on the four sides of the plate surface 2. In the partition 1 having such a configuration, the standing peripheral edge portion 4 ′ is formed on four sides of the rectangular plate surface 2, and the peripheral edge portions are coupled to each other by the reinforcing corner sides, so that the plate surface 2 is reinforced. Thus, the occurrence of warpage of the plate surface 2 can be effectively suppressed.

  Next, when the completed partitions 1 are connected horizontally, as shown in FIGS. 6 and 7, two partitions 1 are prepared, the reinforcing peripheral edge 4b and the reinforcing peripheral edge 4d are joined, and both the partitions are connected. The coupling long holes 15 (three locations, for example, the coupling long holes 15f and 15j) and the coupling long holes 15 ′ (three locations, for example, the coupling long holes 15f ′ and 15j ′) are aligned and coupled. The piece 9a is inserted into the coupling slot 15 up to the center in the direction orthogonal to the standing peripheral edge 4 ′, and the upper end (one end) 18a of the coupling slot 15 is positioned at the lower end 12 ″ of the slit 12 Then, the connecting piece 9a is slid upward until the reinforcing peripheral edge portion 4b and the reinforcing peripheral edge portion 4d of the two partitions can be held by the holding portion 12 'of the connecting piece 9a. For clamping the clamping part 12 'of the piece 9a The two cardboard partitions 1 are connected by sandwiching the cardboard surfaces of the two raised peripheral edge portions 4 'through the coupling slot 15 with the lit 12 (see FIG. 8B). .

  Next, as shown in FIG. 8, the blind-locking piece 9b is orthogonal to the raised peripheral edge 4 'so that the convex curved surface 11a of the coupling piece 9a and the convex curved surface 11b' of the lock piece 9b are aligned. And is inserted into the hole 15 until the lower end (the other end) 18b of the connection long hole 15 is located at the upper end 13 ″ of the slit 13. The reinforcing peripheral edge 4b and the reinforcing peripheral edge 4d of the both partitions can be held by the holding portion 13 'of the blindfolding lock piece 9b, that is, the holding slit 13 of the holding portion 13' of the lock piece 9b. Thus, the corrugated cardboard surfaces of the raised peripheral edge portions 4 ′ are sandwiched through the coupling elongated hole 15. In this way, the lower end 12 ″ of the slit 12 and the upper end 13 ″ of the slit 13 The distance T is the length of the hole Is set to a distance that substantially coincides with the length t of the connecting piece 9a and the blindfolding locking piece 9b are joined (in the state shown in FIG. 8C), the locking piece 9b is connected to the connecting elongated hole. 15 (see FIG. 8).

  The partition can be connected only by the connecting piece 9a. However, when connecting only by the connecting piece 9a, a space S is formed in a part (lower side) of the connecting long hole 15 as shown in FIG. May be formed, and the inside of the partition may be looked into from outside through the space S. Therefore, by fitting the blindfold locking piece 9b into the coupling elongated hole 15, the space S is closed and the peeping is completely prevented (see FIG. 8C). In addition, by fitting the blindfolding lock piece 9b into the coupling long hole 15, there is an effect of improving the coupling strength of the two partitions. Further, by fitting the blindfold lock piece 9b into the elongated hole 15, the coupling piece 9a can be prevented from falling off, and the coupling piece 9a can be locked so as not to be removed.

  Further, the coupling piece component 9 is similarly fitted in the coupling elongated hole 15 ', and the partitions 1 are connected to each other by two coupling piece components 9, 9 at the same height position in the front-rear direction. (See FIG. 7).

  In the embodiment shown in FIG. 7, the coupling piece 9a is attached to the upper side with respect to the coupling long hole 15. However, as shown in FIG. 12, the coupling piece 9a is on the lower side and the blindfolding locking piece 9b is on the upper side. It may be provided.

  Next, when the cardboard partitions 1 are connected at right angles, as shown in FIG. 13, the reinforcing peripheral portions 4d and 4b (stand-up peripheral portions 4 ′) of the two cardboard partitions 1 are orthogonal to each other. The coupling piece parts 9 (the coupling piece 9a and the blindfolding locking piece 9b) are placed in the coupling long holes 15 by aligning the positions of the coupling long holes 15 (for example, the coupling long holes 15k and 15e). Inserted so as to intersect, the cardboards (both right-angled bent parts) of both standing peripheral edge parts 4 'are inserted through the long slot for coupling 15 with the holding slits 12 and 13 of the coupling piece part 9 between them. By sandwiching in the same manner, the cardboard partitions can be connected in an orthogonal state. In this case, since some play is formed in the coupling between the coupling piece component 9 and the coupling elongated hole 15 (see FIG. 13B), the coupling portion K is centered in the coupling state shown in FIG. Each cardboard partition 1 can be angle-changed in the direction of arrow Y in the figure, and the angle θ of the partition can be changed according to the installation location (see FIG. 13B).

  Then, by connecting a plurality of cardboard partitions 1 in a horizontal (left-right direction) or orthogonal state and also horizontally in the vertical direction, an arbitrary shape and an arbitrary size as shown in FIGS. A partition can be formed.

  As described above, since the standing peripheral edge portion 4 ′ is present around the cardboard partition 1 as described above, the plate surface 2 of the partition 1 can be reinforced, and the partition with less warpage can be obtained by one rectangular cardboard plate. A partition device that can be realized and has high storage efficiency with a small amount of material can be realized.

  Further, the standing peripheral edge 4 'can be easily configured, and a partition device that is easy to assemble and has strength can be realized.

  Further, the cardboard partitions can be connected horizontally by the connecting piece parts 9 (the connecting piece 9a and the blindfolding lock piece 9b), and can be connected to the orthogonal state by the same connecting piece part 9 so that the partition 1 is in the orthogonal state. No special parts are required to connect to.

  Moreover, since no pillar is required to configure the partition 1, a cardboard partition device that can be easily assembled with a small number of parts can be realized.

  Further, the long connecting hole 15 can be closed without any gap by the pair of connecting piece parts 9 (the connecting piece 9a and the blindfolding lock piece 9b), thereby preventing peeping and ensuring the privacy inside the partition.

Further, the cardboard partition 1 including the coupling piece component 9 can be formed by one rectangular cardboard plate, and can be easily and efficiently manufactured by punching the cardboard plate.
Incidentally, the thickness of the corrugated board in the present invention is preferably a B flute, but it can be realized by a micro flute having a smaller thickness, or may be a corrugated board having a thickness larger than that of the B flute. It is also possible to use plastic cardboard.

  The cardboard partition device of the present invention can be used extremely effectively in order to ensure the privacy of evacuees, for example, in a wide area such as an evacuation area during a natural disaster.
