Description

  The present invention relates to a functional sheet and a method for attaching the functional sheet.

  Various functional sheets have been developed in order to exert desired functions. Patent Document 1 discloses a heat shielding structure in which a material having a high reflectance with respect to radiant heat is closely attached without providing an air layer on the indoor side of a base material such as an exterior material. In Patent Document 1, a container is taken as an example of an exterior material, and a material having high reflectance with respect to radiant heat is closely attached to the inside of the container to prevent conduction heat that moves the container from the outdoor side to the inside. This suppresses the temperature rise in the container.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
In this embodiment, a functional sheet shall be a heat insulation sheet and the installation position of a heat insulation sheet shall be an inner surface of the side wall of a container.
FIG. 1 is a diagram illustrating an example of the configuration of the container 100.
A container 100 shown in FIG. 1 is for sea transportation and is a so-called dry container. The container 100 is a rectangular parallelepiped whose longitudinal direction is the front and back, and the size is standardized to 20 feet, 40 feet, etc. by the International Organization for Standardization (ISO).

The container 100 is mainly configured by members such as a front end wall 101, a rear end wall 102, a right side wall 103, a left side wall 104, a roof portion 105, and a floor portion 106, and cargo is loaded therein. A space is formed. In addition, the rear end wall 102 functions as a door that can be opened and closed in order to load and unload cargo into the container 100.
The end walls 101 and 102, the side walls 103 and 104, the roof portion 105, and the floor portion 106 described above are made of metal, specifically, steel to which a magnet is adsorbed. Further, at least the side walls 103 and 104 are formed in a corrugated shape or an uneven shape in order to increase rigidity.

Here, the shape of the side wall 103 will be described with reference to FIG. Note that the side wall 104 has the same shape as the side wall 103.
FIG. 4 is a view showing a part of the side wall 103 extracted from the outside of the container 100. In FIG. 4, the roof portion of the container 100 is omitted.
On the side wall 103, convex portions 110 and concave portions 120 are alternately formed over the entire surface of the side wall 103. Here, a portion that protrudes toward the inside of the container 100 with reference to the inside of the container 100 is referred to as a convex portion 110, and a portion that protrudes toward the outside of the container 100 is referred to as a concave portion 120. That is, when the inside of the container 100 is used as a reference, the convex portion 110 projects to the near side, and the concave portion 120 projects to the opposite side to the convex portion 110. Moreover, the convex part 110 and the recessed part 120 are flat form extended respectively up and down. The end portions of the adjacent convex portion 110 and concave portion 120 are joined by an inclined portion 130 that is bridged obliquely in plan view. Here, the distance between adjacent convex portions 110 is a distance L.
Note that the container 100 is not limited to the side walls 103 and 104, and the end walls 101 and 102, the roof portion 105, and the floor portion 106 may be uneven as well.

  When the container 100 as described above is loaded with cargo in an internal space and transported by sea, the container 100 is easily affected by the environment during transport. For example, when transporting in an area where the temperature is high, the side walls 103 and 104 of the container 100 may reach about 60 degrees. In such a case, if the cargo in the container 100 comes into contact with the side walls 103 and 104, the cargo may be deteriorated or damaged due to the temperature.

In the present embodiment, the heat insulating sheet 10 as a functional sheet is attached to the inside of the container 100, specifically, the inner surfaces of the side walls 103 and 104, and the side walls 103 and 104 even if the cargo contacts the side walls 103 and 104. Insulate so that the heat is not transferred to the cargo.
FIG. 1 shows an example in which a plurality of heat insulating sheets 10 are attached to the entire inner surfaces of the side walls 103 and 104. Thus, by attaching the heat insulation sheet 10, it can insulate so that the heat of the side walls 103 and 104 may not be transmitted to the cargo, and can prevent the cargo from being deteriorated or damaged. On the other hand, the container 100 is not configured so that the heat insulating sheet 10 can be attached. Therefore, in this embodiment, it is comprised so that the heat insulation sheet 10 can be easily attached to the side walls 103 and 104 at the heat insulation sheet 10 side. Hereinafter, the structure of the heat insulating sheet 10 that can be easily attached to the side walls 103 and 104 will be specifically described.

FIG. 2 is a diagram illustrating an example of the configuration of the heat insulating sheet 10 as viewed from the back side.
The heat insulating sheet 10 according to the present embodiment includes a sheet main body 20 and a plurality of magnets 30 provided on the sheet main body 20.
The sheet main body 20 has a rectangular sheet shape with the top and bottom as the longitudinal direction. The seat body 20 of the present embodiment is configured such that the vertical height Hs is approximately 2300 mm in accordance with the size of the side walls 103 and 104 that are the installation positions. Further, the sheet body 20 of the present embodiment is configured to have a width Ws of about 1600 mm so that the installer can easily handle it. However, the size of the seat body 20 can be changed to any size according to the size and purpose of the installation position.

Moreover, the sheet | seat main body 20 is comprised with the raw material with high heat insulation. For example, the sheet body 20 may be a sheet in which an aluminum alloy foil on the front side, a bubble-filled sheet, and an aluminum alloy foil on the back side are adhered and laminated. However, the material of the sheet body 20 can be changed according to the required degree of heat insulation.
For convenience of explanation, one of the wide surfaces of the sheet body 20 is shown as a front surface 21a, and the other surface is shown as a back surface 21b. In addition, the four sides constituting the rectangle of the sheet body 20 are shown as an upper side 22a, a side side 22b, a side side 22c, and a lower side 22d, respectively.

  A plurality of (here, six) magnets 30 are provided at positions close to the upper side 22a of the sheet main body 20. Specifically, the magnets 30 are provided on the back side of the sheet main body 20 and are spaced from each other in the width direction of the sheet main body 20. The magnet 30 of the present embodiment is a disc having a diameter of about 13 mm, and a neodymium magnet having a strong magnetic force is used.

FIG. 3 is a perspective view showing a configuration around the magnet 30.
The magnet 30 of the present embodiment is provided in the sheet main body 20 via the container 40 by being accommodated in a bag-shaped container 40 coupled to the sheet main body 20. One magnet 30 is accommodated in one container 40.
Similar to the magnet 30, a plurality (six in this case) of the containers 40 are provided. Specifically, the containers 40 are provided on the back side of the sheet main body 20 and are spaced apart from each other in the width direction of the sheet main body 20 similarly to the magnet 30. Each of the containers 40 has a rectangular shape whose longitudinal direction is the width direction of the sheet main body 20. The container 40 of the present embodiment is configured such that the width Wc of the storage space is about 150 mm to 170 mm and the height Hc is about 20 to 30 mm. Therefore, the magnet 30 can freely move in the accommodation space of the accommodation body 40. In addition, it is preferable to set the width Wc of the storage space to a distance longer than the distance L that is the interval between the adjacent convex portions 110 of the side wall 103 described above.

  The container 40 is coupled to the sheet body 20 at a position where the lower end is separated from the upper side 22a of the sheet body 20 by a distance D. The distance D is a distance longer than the diameter of the magnet 30 or the height Hc of the container 40. Therefore, when the heat insulating sheet 10 is viewed from the surface side, the magnet 30 and the container 40 are not seen beyond the upper side 22a. Further, only the lower end of the container 40 is coupled to the sheet main body 20 along the width direction, and other portions are separated from the sheet main body 20. Further, among the containers 40, the containers 40 located on both sides in the width direction of the sheet body 20 are coupled to the sheet body 20 at positions separated from the side edges 22b and 22c by a distance G, respectively. In other words, the container 40 does not exist within the distance G from the side sides 22b and 22c. An interval I is formed between adjacent containers 40. Since the accommodation space of the container 40 does not exist in the range of the interval I, the magnet 30 cannot move within the range of the interval I. The interval I is a distance set to prevent the magnets 30 accommodated in the adjacent containers 40 from being attracted to each other.

  Moreover, the mesh-shaped raw material is used for the container 40 of this embodiment so that the position of the magnet 30 which the installer accommodated can be confirmed from between meshes. In the present embodiment, the plurality of containers 40 are configured by stitching long mesh-shaped fabrics so as to overlap each other and divide into each storage space. Therefore, the manufacturing cost can be reduced as compared with the case where the containers 40 are configured one by one. Further, the container 40 is joined to the seat body 20 by sewing together with the seat body 20.

Next, an attachment method for attaching the heat insulating sheet 10 to the side wall 103 will be described.
FIG. 4 is a perspective view showing a state before the heat insulating sheet 10 is attached to the inner side surface of the side wall 103, as viewed from the outside of the container 100.
The installer holds the heat insulating sheet 10 so that the back surface 21b of the sheet body 20 and the inner surface of the side wall 103 face each other. Here, among the plurality of magnets 30 (30a to 30d), the magnets 30a and 30b face the convex portion 110 of the side wall 103, and the magnets 30c and 30d face the concave portion 120 of the side wall 103. Next, the installer brings the held heat insulating sheet 10 close to the inner surface of the side wall 103. When the heat insulating sheet 10 approaches the inner side surface of the side wall 103, the magnet 30 provided on the back surface 21 b of the sheet main body 20 is attracted to the inner side surface of the steel side wall 103 by magnetic force.

FIG. 5 is a perspective view showing a state after the heat insulating sheet 10 is attached to the inner side surface of the side wall 103, as viewed from the outside of the container 100. In FIG. 5, the side wall 103 is indicated by an imaginary line (two-dot chain line).
As shown in FIG. 5, the magnet 30 is attracted to the surface of the convex portion 110 of the side wall 103, whereby the heat insulating sheet 10 is attached to the inner side surface of the side wall 103. At this time, among the plurality of magnets 30 (30a to 30d), the magnets 30a and 30b facing the convex portion 110 are directly attracted to the convex portion 110. On the other hand, among the plurality of magnets 30 (30a to 30d), the magnets 30c and 30d facing the concave portion 120 are accommodated so as to be attracted to the convex portion 110 of the side wall 103 when approaching the inner surface of the side wall 103. Move in the body 40. Therefore, after the heat insulating sheet 10 is attached to the inner side surface of the side wall 103, all of the magnet 30 is attracted to the surface of the convex portion 110.

Moreover, the installer can attach another heat insulation sheet 10 next to the heat insulation sheet 10 attached in the same manner as the attachment method described above. At this time, it is preferable that the sheet main bodies 20 of the adjacent heat insulating sheets 10 are overlapped so that no gap is generated between the adjacent heat insulating sheets 10. As described above, the sheet main body 20 can easily overlap the sheet main bodies 20 in the range of the distance G because the container 40 does not exist within the range of the distance G from the side edges 22b and 22c. it can. The installer can cover the entire surface of the side wall 103 with the heat insulating sheet 10 by attaching the heat insulating sheet 10 to the entire inner surface of the side wall 103. Therefore, even if the cargo accommodated in the container 100 comes into contact with the side wall 103, the heat of the side wall 103 is insulated so as not to be transmitted to the cargo, and deterioration and damage of the cargo can be prevented.
When the installer removes the heat insulating sheet 10 from the side wall 103, the heat insulating sheet 10 can be removed by holding the sheet main body 20 and pulling the magnet 30 away with a force higher than the magnetic force attracted to the side wall 103. . Thus, according to this embodiment, the heat insulation sheet 10 can be easily removed from an installation position.

Further, the installer can easily confirm whether or not the magnet 30 of the heat insulating sheet 10 attached is attracted to the side wall 103.
FIG. 6 is a perspective view showing a state in which the heat insulating sheet 10 is attached to the inner side surface of the side wall 103, as viewed from the inside of the container 100. As shown in FIG. 6, the installer can turn (turn) the upper side 22a of the sheet body 20 toward the front side. By turning the upper side 22a of the sheet main body 20 toward the front side, the position of the magnet 30 in the container 40 can be confirmed. Thus, the reason why the upper side 22a can be rolled is that the container 40 is not connected to the upper side 22a but is connected to the sheet main body 20 at a position away from the upper side 22a by the distance D. .
The installer confirms whether or not the magnet 30 is attracted to the side wall 103, and if there is a magnet 30 that is not attracted to the side wall 103, the inside of the container 40 reaches the installation position where the magnet 30 that is not attracted can be attracted. The magnet 30 can be attracted to the side wall 103 by moving.

  Thus, according to this embodiment, the heat insulation sheet 10 can be easily attached to an installation position by making the magnet 30 provided in the sheet | seat main body 20 adsorb | suck to the inner surface of the side wall 103 of the container 100. FIG. At this time, since the magnet 30 is provided so as to be movable with respect to the sheet main body 20, even if the inner surface of the side wall 103 is uneven, the magnetic force acting between the magnet 30 and the convex portion 110 causes the sheet main body. It moves to 20 and is attracted to the convex part 110. Therefore, the installer can attach the heat insulation sheet 10 to the installation position simply by bringing the heat insulation sheet 10 closer to the installation position without being aware of whether the installation position facing the magnet 30 is attracted to the magnet 30 or not. it can.

  Moreover, since the magnet 30 moves with respect to the sheet | seat main body 20, and attracts | sucks to the convex part 110, many of the magnets 30 can be made to contribute to attachment of the heat insulation sheet | seat 10. FIG. On the other hand, if the magnet 30 cannot be moved with respect to the seat body 20, it is necessary to increase the number of the magnets 30 in anticipation of the magnets 30 that do not contribute to attachment, which may increase the manufacturing cost. There is. Therefore, by providing the magnets 30 so as to be movable with respect to the sheet main body 20, the number of the magnets 30 can be reduced, and the manufacturing cost of the heat insulating sheet 10 can be reduced.

Moreover, according to this embodiment, the magnet 30 is provided so that the inside of the container 40 can be moved. Therefore, the magnet 30 can be prevented from being detached from the sheet main body 20.
Moreover, according to this embodiment, since the container 40 is comprised with the raw material which can visually recognize the magnet 30 from the outside, the position of the magnet 30 in the container 40 can be confirmed easily. Therefore, the installer can confirm whether the magnet 30 is attracted to the installation position.

Further, according to the present embodiment, the installation position is a mounting surface having the convex portion 110 and the concave portion 120, and the magnet 30 is attracted to the convex portion 110. Thus, even when the installation position has a special shape, the heat insulating sheet 10 can be easily attached to the installation position.
Moreover, according to this embodiment, the installation position is a mounting surface on which the convex portions 110 and the concave portions 120 are alternately formed, and the magnet 30 has the same direction as the direction in which the convex portions 110 and the concave portions 120 are alternately formed. Can be moved to. Therefore, even if the magnet 30 faces the concave portion 120 before the attachment, the magnet 30 is attracted to the convex portion 110 by moving toward the convex portion 110, and the heat insulating sheet 10 is easily attached to the installation position via the magnet 30. be able to.
