Description

[Technical Field]

[0001] The present invention relates to a partition assembly set in which a plurality of partition paperboards are connected with fasteners, and to the fasteners. [Background technology]

[0002] BACKGROUND ART Conventionally, a fastener that uses a clip to connect adjacent partitions is known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3118711 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, in order to make partitions easier to install and dispose of, it has been considered to construct partitions out of paper products such as cardboard. However, when partitions are connected with clips, the clips are made of metal, so it is necessary to separate the partitions from the clips when disposing of them, which is troublesome.

[0005] Furthermore, when installing a large number of partitions, a large number of clips must be prepared, which are heavy and bulky, making them inconvenient to transport and store.

[0006] In view of the above, an object of the present invention is to provide a partition that is easy to dispose of, transport, and store, and a fastener for connecting multiple partition paperboards. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the fastener of the first invention is a paper fastener for connecting partitions, which overlaps at least a portion of a set of partition paperboards and fixes their corners, and is characterized by having a main body portion extending in the vertical direction, a locking hole formed in the main body portion into which the corners of the partition paperboards are fitted, a claw portion having a slit into which the edge of the partition paperboards is clamped, a bridge portion connecting at least one of the upper and lower end edges of the main body portion to the base end of the claw portion, and a bridge portion fold line connecting the left and right side edges of the bridge portion.

[0008] According to the first aspect of the present invention, the corners of the partition paperboard can be fitted into the locking holes, thereby securing the partition paperboard. Furthermore, the claws can grip the edges of the partition paperboard, thereby increasing the securing force. Furthermore, because the clips are made of paper, they are lighter than metal clips. Furthermore, while they are folded along the crease in the bridge section during use, they remain flat before and after use, making them less bulky and easier to transport and dispose of.

[0009] Furthermore, in the first fixing device of the present invention, it is preferable that the bridge fold line comprises a first bridge fold line formed along the boundary line between the bridge and the main body, and a second bridge fold line formed along the boundary line between the bridge and the claw, and that the locking hole extends to the first bridge fold line and the slit extends to the second bridge fold line.

[0010] With this configuration, the inner surface of the bridge portion can be pressed against and engaged with the edge of the partition paperboard over the entire vertical direction, thereby further increasing the fixing force.

[0011] In order to achieve the above-mentioned object, the fastener of the second present invention is a paper fastener for connecting partitions, which overlaps at least a portion of a set of partition paperboards and fixes their corners, and is characterized by having a main body portion extending in the vertical direction, a locking hole formed in the main body portion into which the corner of the partition paperboard is inserted, and a bridge portion connected to at least one of the upper and lower end edges of the main body portion via a first bridge portion fold line.

[0012] According to the second invention, the corners of the partition paperboard can be fitted into the locking holes, thereby securing the partition paperboard. Furthermore, the inner surface of the bridge can be pressed against the edge of the partition paperboard to secure it, thereby increasing the fixing force. Furthermore, because the clip is made of paper, it is lighter than a metal clip. Furthermore, while it can be folded along the crease in the bridge when in use, it can be flattened before and after use, making it less bulky and easier to transport and dispose of.

[0013] Furthermore, in the fasteners of the first and second aspects of the present invention having a configuration with a first bridge fold line, it is preferable that the fastener has a protruding piece that straddles the main body and the bridge and is defined by a cut line that is convex upward or downward, and that when the bridge and the main body are bent at the first bridge fold line, the protruding piece that comes out from the cut line is engaged with the edge of the cut line from which the protruding piece comes out, thereby maintaining the bent state.

[0014] With this configuration, the bridge portion bent at the first bridge portion fold line can maintain its bent state with the protrusion without stretching due to elastic recovery at the first bridge portion fold line relative to the main body portion where the corners of the partition paperboard are inserted into the locking holes, so that the edge of the partition paperboard can be securely locked by the inner surface of the bridge portion, further increasing the fixing force.

[0015] In order to achieve the above object, a partition assembly set according to the third aspect of the present invention comprises the fixture according to the first aspect of the present invention or the fixture according to the second aspect of the present invention, and at least one set of partition paperboards.

[0016] The partition assembly set in the third invention is made entirely of paper, so it is lightweight, and when in use it is folded along the fold lines in the bridge section or along fold lines provided appropriately on the partition paperboard, but it can be folded into a flat sheet before and after use, so it is not bulky and is easy to transport and dispose of.

[0018] A partition assembly set and fixtures according to an embodiment of the present invention will be described with reference to the drawings.

[0019] Figure 1 shows a partition 1 assembled using the partition assembly set of the present invention. The partition 1 comprises a partition paperboard 2, leg members 3 attached to the lower ends of the partition paperboard, and fasteners 4 that connect adjacent partition paperboards 2. The partition paperboard 2, leg members 3, and fasteners 4 that make up the partition 1 are all made of cardboard.

[0020] The partition board 2 comprises a rectangular panel body 21 and rectangular connecting flaps 22 connected to both side edges of the panel body 21 via panel fold lines K so as to be able to swing freely.

[0021] In Figure 1, the panel body 21 and the connecting flap 22 are basically folded at approximately 90° at the panel fold line K, and the left side of the right-most partition board 2 and the right side of the adjacent central partition board 2 are folded at an acute angle (approximately 45°) at the panel fold line K.

[0022] The folded connecting flaps 22 are overlapped back to back with the connecting flaps 22 of the adjacent partition paperboards 2. The overlapping connecting flaps 22 are fixed together with fasteners 4, thereby connecting the adjacent partition paperboards 2 together.

[0023] Leg members 3 are attached to the lower end of the partition paperboard 2. In addition to being bent into a U-shape when viewed from above, the partition paperboard 2 is held in an upright position by being clamped by the leg members 3.

[0024] 2, the fixture 4 includes a rectangular main body 41 extending in the vertical direction, and a pair of bridges 42 connected to the upper and lower ends of the main body 41. A claw 43 is connected to the upper end of the upper bridge 42 and the lower end of the lower bridge 42, respectively.

[0025] A first bridge fold line A is formed along the boundary line between the main body 41 and the bridge 42. A second bridge fold line B is formed along the boundary line between the bridge 42 and the claw 43.

[0026] A locking hole 44 is formed in the left-right center of the main body 41, extending from the lower end of the upper bridge portion 42 to the upper end of the lower bridge portion 42. The corners of the two overlapping connecting flaps 22 are fitted into the locking hole 44, so the width of the locking hole 44 is set to approximately twice the thickness of the connecting flap 22.

[0027] A slit 45 is formed in the center of the claw portion 43 in the left-right direction up to its base end (the lower end of the upper claw portion 43 and the upper end of the lower claw portion 43). This forms the claw portion 43 into a bifurcated shape as a whole. The upper end or side end of the two overlapping connecting flaps 22 is sandwiched in the slit 45, so the width of the slit 45 is set to about twice the thickness of the connecting flap 22.

[0028] A pair of L-shaped cut lines 46 are provided on both ends of the first bridge fold line A. These cut lines 46 define protruding pieces 47 that protrude from the main body 41 to the bridge 42 and straddle the first bridge fold line A.

[0029] Next, a method for connecting adjacent partition paperboards 2 using the fastener 4 of this embodiment will be described with reference to Figures 3 and 4. As a prerequisite, as shown in Figure 1, the partition paperboards 2 are folded along the panel fold line K into a U-shape in plan view, and the connecting flaps 22 of two adjacent partition paperboards 2 are folded toward the panel body 21 and overlapped back to back.

[0030] 3, the pair of bridge portions 42 are first bent at approximately 45° along the first bridge portion fold line A relative to the main body portion 41. This causes the protrusions 47 to slip out of the cut lines 46. Because the protrusions 47 have the thickness of the cardboard, the inner surfaces of the protrusions 47 are retained by the peripheral edges of the cut lines 46 (the outer surfaces of the bridge portions 42), and the protrusions 47 are maintained in the bent state.

[0031] Next, as shown in Fig. 4, the corners of the connecting flap 22 are fitted into the locking holes 44 of the fastener 4. At this time, by adjusting the main body 41 so that it forms an angle of approximately 45° with respect to the corners of the connecting flap 22, the pair of bridge portions 42 are positioned so that they are aligned along the upper edge or side edge of the connecting flap 22, respectively.

[0032] Next, as shown in FIG. 3, the claws 43 of each bridge portion 42 are folded at approximately 90° along the second bridge fold line B, and the upper or side edge of the connecting flap 22 is fitted into the slit 45.

[0033] Next, the effects of the fixture 4 of this embodiment and the partitions 1 connected thereto will be described.

[0034] The fixture 4 of this embodiment and the partition 1 including it are all made of cardboard, making them lightweight. Furthermore, when in use, they are folded along the first bridge fold line A, the second bridge fold line B, and the panel fold line K, but because they can be folded into a flat plate before and after use, they are not bulky and are easy to transport and dispose of.

[0035] In addition, according to the fastener 4 of this embodiment, the corners of a set of overlapping connecting flaps 22 can be inserted into the locking holes 44 of the fastener 4, making it possible to easily fix the partition paperboard 2.

[0036] Furthermore, with the fastener 4 of this embodiment, the inner surface of the bridge portion 42 can be pressed against and engaged with the upper and side edges of the overlapping pair of connecting flaps 22 over the entire vertical area, further increasing the fastening force. In particular, the bridge portion 42 is maintained in a bent state relative to the main body portion 41 by the protrusions 47, so that the inner surface can be reliably pressed against and engaged with the pair of connecting flaps 22.

[0037] Furthermore, according to the fastener 4 of this embodiment, the upper edge and side edge of the pair of overlapping connecting flaps 22 can be clamped by the claws 43, thereby further increasing the fastening force.

[0038] Next, a modified example of the present invention will be described.

[0039] In this embodiment, the partition 1 has been described as having a partition cardboard 2, leg members 3, and fasteners 4, but the leg members 3 can be omitted. Also, the partition 1 has been described as being made of cardboard, but it may also be made of cardboard or the like.

[0040] In this embodiment, the partition paperboard 2 has been described as comprising a rectangular panel body 21 and rectangular connecting flaps 22 that are freely swingably connected to both side edges of the panel body 21 via panel fold lines K, but there are no limitations on the shape of the partition paperboard 2. For example, partition paperboards 2 that can be bent into an L-shape in a planar view may be connected in a daisy chain, or partition paperboards 2 that are U-shaped or L-shaped in a planar view may be connected to the left and right ends of a flat partition paperboard 2 with no folds.

[0041] Furthermore, the fasteners 4 are not limited to those that fit into the four corners of the partition paperboard 2. In other words, it is also possible to stack partition paperboards 2 with concave cutouts in the middle of the edges, and fit the fasteners 4 into the corners created by the concave cutouts.

[0042] In this embodiment, a pair of claw portions 43 has been described, but the present invention is not limited to this, and the claw portion 43 may be one, or may be completely omitted as shown in Figure 5 (second embodiment).

[0043] In this embodiment, the bridge portion 42 is provided in a pair, but the present invention is not limited to this, and the bridge portion 42 may be provided in a single portion.

[0044] In this embodiment, the bridge fold line has two fold lines, the first bridge fold line A and the second bridge fold line B, but the present invention is not limited to this. That is, if the claws 43 are omitted as in the second embodiment (FIG. 5), the second bridge fold line B can also be omitted. Also, a single bridge fold line may be provided in the vertical middle of the bridge 42. In this case, the upper and side edges of the pair of connecting flaps 22 overlapping on the inner surface of the bridge 42 cannot be locked, but the bridge 42 can be bent in an L-shape so that the claws 43 can clamp the upper and side edges of the connecting flaps 22.

[0045] In this embodiment, the locking hole 44 is formed from the top to the bottom end at the center of the main body 41 in the left-right direction, but the left-right position and the vertical length of the locking hole 44 are not limited to those in this embodiment. Similarly, the left-right position and the vertical length of the slit 45 formed in the claw portion 43 are not limited to those in this embodiment.

[0046] In this embodiment, a pair of cut lines 46 are provided at both ends of the first bridge portion fold line A, but the cut line 46 may be one, or may be completely omitted as shown in Figure 6 (third embodiment).

[0047] Furthermore, although the cut line 46 has been described as being L-shaped and formed at both ends of the first bridge fold line A, the cut line 46 may also be U-shaped and formed in the middle of the first bridge fold line A in the left-right direction so as to divide the first bridge fold line A.

[0048] Furthermore, although the cut lines 46 have been described as being convex toward the bridge portion 42, they may also be convex toward the main body portion 41. [Explanation of symbols]
