Hereinafter, one aspect of the mobile partition of the present invention (the present embodiment) will be described.
The present embodiment is a mobile partition in which a rectangular plate-shaped body has one or more cut portions extending in the vertical direction, and at least two wall portions are formed by bending the cut portions, and the wall portions are self-supporting.
The "mobile partition" in the present embodiment means a partition that can be carried by a person and can be easily used at a destination, for example.
Hereinafter, the drawings and the like will be described with reference to them as appropriate.

The rectangular plate-shaped body 10 illustrated in FIG. 1 has three notches 12A and 12B in the vertical direction perpendicular to the longitudinal direction (horizontal direction) thereof. By bending these notches so as to open, three wall portions 14A, 14B, and 14C are formed as shown in FIG. 2, and these wall portions are self-supporting. The part left by the notch becomes a bent part that can be bent.

From the viewpoint of good self-sustaining retention, the thickness of the rectangular plate-like body (thickness of the wall portion) is preferably 2 to 12 mm, more preferably 2 to 8 mm or 8 to 10 mm.

The depth of cut provided in the rectangular plate-shaped body is set according to the thickness thereof. When the thickness of the rectangular plate-shaped body is 2 to 8 mm, the ratio (D / T) of the cutting depth (D) to the thickness (T) is 0.5 to 0.7. If the D / T is less than 0.5, it may be difficult to bend or it may open from the bent state. If it exceeds 0.7, the thickness of the bent portion becomes small, and as the bending is repeated, the bent portion may be cracked and the bending strength may be repeatedly lowered. The D / T is preferably 0.5 to 0.7, more preferably 0.6 to 0.7.

When the thickness (T) of the rectangular plate is 8 to 12 mm, the ratio (D / T) of the cutting depth (D) to the thickness (T) of the rectangular plate is 0.7 to. It is set to 0.9. If the D / T is less than 0.7, it may be difficult to bend or it may open from the bent state. If it exceeds 0.9, the thickness of the bent portion becomes small, and as the bending is repeated, the bent portion may be cracked and the bending strength may be repeatedly lowered. The D / T is preferably 0.7 to 0.9, more preferably 0.8 to 0.9.

As described above, in the present embodiment, the cutting depth of the cut portion is adjusted according to the thickness of the rectangular plate-shaped body, and the cut portion is easy to bend, and a practical mobile partition having good repeated bending strength is realized. ing. Further, by folding from the cut portion as a starting point, it can be made compact and the storability can be improved.

From the viewpoint of easy adjustment of the cutting depth and obtaining good repeated bending strength, it is preferable that at least a part of the rectangular plate-shaped body is made of plastic corrugated cardboard.

Plastic corrugated cardboard (hereinafter, may be referred to as "corrugated plastic") is a plate-like body having a hollow structure having a harmonica-like cross section in the direction of the eyes, which is manufactured by integral extrusion molding using polypropylene as a raw material. Corrugated plastics are lighter than plastic sheets in a closed state, can maintain moderate strength, and have hinge characteristics that are resistant to repeated bending. In addition, since it has good workability, it can be easily cut with a utility knife or provided with a notch.

Here, the eye direction refers to the direction in which the hollow structure is flowing, and is easy to break in the eye direction and difficult to break in the direction perpendicular to the eye direction (the cross-sectional direction of the harmonica). Therefore, when the notch is provided in the corrugated plastic, it is preferable to provide the notch in the direction perpendicular to the eye direction.

In the present embodiment, a transparent sheet portion may be provided on at least one wall portion. By providing a transparent sheet part, it becomes easier for light to enter and the inside of the mobile partition becomes brighter.

The wall of a general partition is opaque as in Patent Documents 1 to 3. This is because the opacity makes the work space formed by the partitions closed, which is convenient for concentrated work.

However, face-to-face communication is required at learning sites, sales activities, internal and external meetings, etc. If the wall is opaque, good communication will be hindered. In such a case, if there is a transparent part as described above, the state of the face-to-face person and the material presented by the face-to-face person can be confirmed, so that communication with the face-to-face person becomes easy. Nowadays, it is required to prevent splashing, but if there is a wall having a transparent part, good communication can be achieved without worrying about splashing.
From such a point, it is preferable to provide a transparent sheet portion on at least one wall portion. In this case, it is preferable that the corrugated plastic constitutes the frame of the mobile partition.

The transparent sheet portion is preferably provided in the central portion of the wall portion from the viewpoint of light uptake and good communication. The area ratio ( _ST / _SW ) between the area ( _ST ) of the transparent sheet portion provided on one wall portion and the area ( _SW ) of the wall portion may be 0.5 to 0.9. It is preferably 0.7 to 0.85.

The total light transmittance of the transparent sheet portion is preferably 80% or more, and more preferably 90% or more. The total light transmittance can be measured according to JIS K73752008 "Plastic-How to determine the total light transmittance and the total light reflectance".

A transparent plastic sheet can be used as the transparent sheet constituting the transparent sheet portion, but a polyester sheet such as a PET (polyethylene terephthalate) sheet, for example, can be used from the viewpoint of transparency and wiping property of wiping off splashes and stains with alcohol or the like. Is preferable. The thickness of the transparent sheet is preferably 0.100 to 0.188 mm, for example.

Further, in the present embodiment, the number of wall portions is not particularly limited and may be 2 or more, but the number of wall portions is preferably 3 in consideration of stability and effective use of space. In this case as well, the transparent sheet portion may be provided on at least one wall portion, or may be provided on all three portions. Further, each wall portion may be colored in the same color or may be colored in a different color.
