Embodiments of the present invention will be described in the following order. In addition, this invention is not limited to the following examples.
1. 1. Configuration of corrugated tiger cushion Corrugated sheet cushion manufacturing method

<1. Configuration of corrugated tiger cushion>
FIG. 1 shows a plan configuration of a corrugated sheet cushion according to an embodiment of the present invention, and FIG. 2 shows a cross-sectional configuration along the line AA ′ in FIG.

  As shown in FIGS. 1 and 2, the corrugated sheet cushion 1 of the present embodiment is composed of a cushion material 2 made of polyethylene foam and a polyethylene film 3 bonded to the surface side of the cushion material 2, and on the surface. A plurality of concave and convex shapes (waveforms) extending in the vertical direction are formed.

  The thickness h of the cushion material 2 is preferably configured to be 5 mm or more and 15 mm or less, and in the present embodiment example, the thickness h is about 10 mm. When the thickness is less than 5 mm, there is a problem that good cushioning properties cannot be obtained, and when it is thicker than 15 mm, there is a problem that heat is not conducted to the center when heat treatment is performed in the manufacturing process. .

  The polyethylene film 3 is configured to have a thickness of about 50 μm to 300 μm, and a tiger mark 9 is formed on the surface. The tiger mark 9 is composed of black and yellow stripes having a line width of a desired thickness, and is displayed at an angle of 45 °, for example, with respect to the uneven shape extending in the vertical direction.

  And it is preferable that the width W1 of the uneven | corrugated shaped convex part 4 shall be 5 mm or more and 50 mm or less, and it is about 20 mm in this embodiment. By setting it to 5 mm or more and 50 mm or less, the corrugated sheet cushion 1 can be used flexibly as described later. The width W2 of the recess 5 is preferably 1 mm or more and 20 mm or less, and is formed to be about 1 mm in this embodiment. If it is less than 1 mm, the production is difficult, and if it is greater than 20 mm, the area of the convex portion 4 is reduced and the cushioning property may be reduced.

  The corrugated sheet cushion 1 according to this embodiment can be used by being wound around a dangerous part such as a utility pole or a corner of a building. The corrugated sheet cushion 1 of the present embodiment is formed with a plurality of concave and convex shapes extending in the vertical direction, and the cushion material 2 corresponding to the concave portion 5 is thin, so that the flexibility of the bottom portion of the concave portion 5 is increased. It becomes easy to bend on the opposite side to the uneven surface. That is, as in this embodiment, even when the cushion material 2 having a certain thickness is used, the flexibility is improved by forming the uneven shape. Thereby, it can be bent flexibly along a hard substance. In addition, by setting the convex and concave portions to 50 mm or less and setting the interval at which the bottom of the concave portion 5 (that is, the flexible and easy to bend portion) is formed to be relatively fine, it fits sharp corners. It becomes possible to wind in the state.

Further, in the corrugated tiger cushion 1 according to the present embodiment, the tiger mark 9 is displayed at an angle of 45 ° with respect to the concavo-convex shape. The Rukoto. Moreover, since the corrugated sheet cushion 1 of this embodiment is comprised with the cushioning material 2 which consists of polyethylene foams, it can absorb impacts, such as a collision, and can reduce the damage of collision holding | maintenance.
Furthermore, the uneven shape attached to the corrugated tiger cushion 1 has an effect of not only improving the easiness of bending (flexibility) but also increasing the shock absorption capacity.

<2. Manufacturing method of corrugated tiger cushion>
Next, the manufacturing method of the corrugated sheet cushion 1 of this embodiment example is shown using FIG. 3A-FIG. 3C.

  First, as shown in FIG. 3A, a cushion material 2 made of polyethylene foam is formed. The cushion material 2 can be formed by heating a polyethylene material mixed with a foam material with heat of 130 ° C. The cushion material 2 is made of polyethylene foam having a foaming ratio of 10 to 40 times. Moreover, the thickness of the cushion material 2 shall be 5 mm or more and 15 mm or less. If the expansion ratio is 10 times or less, the cushion material 2 cannot be formed to a thickness of 5 mm or more, and if it is 40 times or more, the strength becomes weak and cushioning properties cannot be obtained. Moreover, when the thickness of the cushion material 2 is thicker than 15 mm, as described above, there is a problem that heat is not conducted to the central portion in the heat treatment step. In the present embodiment example, the cushion material 2 having an expansion ratio of 30 times and a thickness of about 10 mm was formed.

  Next, as shown in FIG. 3B, the polyethylene film 3 on which the tiger mark 9 is printed is adhered to the upper surface of the cushion material 2 made of polyethylene foam. The polyethylene film 3 is made of the same material as that of the cushion material 2, and a tiger mark 9 is printed on the surface side opposite to the adhesive surface. The tramark 9 can be formed by gravure printing, for example. In this case, black stripes may be printed on the polyethylene film 3 whose entire surface is yellow, or yellow stripes may be printed on the polyethylene film 3 whose entire surface is black. Further, black and yellow stripes may be printed on a transparent polyethylene film.

  Since the tiger mark 9 is a display for recognizing the dangerous part more conspicuously, it is preferable that the contrast between the black and yellow stripe patterns is made clearer. In a later process, the printed pattern may be thinned by applying a tensile stress to the polyethylene film 3. In particular, when black stripes are printed on the yellow polyethylene film 3, the black stripes are faded. In this case, it is preferable to devise such as configuring the cushion material 2 as a base in black. Moreover, the above-mentioned problem is reduced by printing yellow stripes on the black polyethylene film 3.

  Adhesion between the cushion material 2 and the polyethylene film 3 can be easily performed by disposing the polyethylene film 3 on the upper surface of the cushion material 2 and heating at 80 ° C to 100 ° C. This is because the cushion material 2 and the polyethylene film 3 are both made of polyethylene, and the melting point of polyethylene is 80 ° C.

  Thereafter, the four sides around the cushion material 2 having the polyethylene film 3 bonded to the upper surface are supported by a clamp and heated with heat of about 80 ° C. Then, the cushion material 2 and the polyethylene film 3 are softened and become deformable. In that state, as shown in FIG. 3C, next, the mold 6 having the concavo-convex portion is cooled and pressed against the surface of the cushion material 2 on the side to which the polyethylene film 3 is bonded, and the cushion material 2 and polyethylene as it is. The film 3 is cooled. Thereby, the uneven | corrugated | grooved part of a type | mold is transcribe | transferred to the cushion material 2 to which the polyethylene film 3 was adhere | attached on the upper surface, and the corrugated sheet | seat cushion 1 of this embodiment example is completed.

  In this step, since the cushion material 2 and the polyethylene film 3 are made of the same material, the elongation rates generated in the cushion material 2 and the polyethylene film 3 are the same when the mold 6 is pressed against the surface. For this reason, an uneven | corrugated | grooved part is transcribe | transferred in the state closely_contact | adhered to the cushioning material 2, without wrinkling or bending the polyethylene film 3. FIG.

  FIG. 4 is a perspective view of the corrugated sheet cushion 1 in the present embodiment. As shown in FIG. 4, in the corrugated sheet cushion 1 according to the present embodiment, the cross section has an uneven shape, and the uneven shape is formed to extend in the vertical direction. In addition, a tiger mark 9 made of black and yellow stripes is formed on the surface.

  The corrugated tiger cushion 1 according to the present embodiment can be used by placing the surface on which the tiger mark 9 is formed on the outside and winding it around a desired location. In this case, since the concavo-convex shape is formed, the cushion material 2 is easy to bend along the concavo-convex shape, and can be used by being freely wound around various places.

  The corrugated tiger cushion 1 of the present embodiment is used by being wound around a desired location, so that the surface of the cushion material 2 opposite to the surface on which the tiger mark 9 is formed is bonded to another location. It is preferable that the part is formed. As the bonding part, a commercially available double-sided tape may be used, or a magnet may be attached. Moreover, you may give the adhesion process to the back side.

  In the case where an adhesive process is applied to the back side of the corrugated sheet cushion 1, first, a desired paper is prepared, a silicon coating is applied to the upper surface of the paper, and a liquid paste is formed on the upper surface of the silicon. And after drying the solvent of a liquid paste, the back surface side of the corrugated sheet cushion 1 is bonded to the upper part. If it does in this way, when using the corrugated sheet cushion 1, it will be exposed in the state in which the adhesive surface was formed in the back surface side of the cushion material 2 by peeling the paper of a back surface side. Thereby, it becomes possible to affix the corrugated sheet cushion 1 to a desired location.

  In the method for manufacturing the corrugated sheet cushion 1 according to the present embodiment, the cushioning material 2 and the polyethylene film 3 formed on the upper surface of the cushion material 2 are formed of the same material, thereby causing problems in the manufacturing process due to different material characteristics. Therefore, the manufacturing process can be simplified.

  As described above, according to the corrugated sheet cushion 1 of the present embodiment, since the plurality of uneven shapes extending in the vertical direction are formed on the surface, the cushion material 2 is formed with a surface on which the uneven shapes are formed. Becomes easier to bend to the opposite side. Thereby, it becomes possible to wind while adapting a shape according to various dangerous places. In addition, according to the corrugated tiger cushion 1 of the present embodiment example, since the tiger mark 9 is formed on the surface side to alert the dangerous place, the danger can be notified to the surroundings. Furthermore, since it has cushioning properties, even if a vehicle or the like collides with a portion where the corrugated sheet cushion 1 is wound, the damage of the collided members can be reduced.
