Abstract
Description
[Technical Field]
[0001] The present invention relates to a post repair sheet that repairs and decorates the surface of a post slot formed in a door for inserting mail when renovating a building such as an apartment building. [Background technology]
[0002] Traditionally, public buildings, residential buildings, kindergartens, daycare centers, and other buildings have undergone exterior renovations as needed to extend their lifespan. Renovations replace the exterior walls, floors, and other surfaces of the building with new exterior materials, creating a different environment than before. Typically, a postbox is attached to the door at the entrance to a building, and mail is dropped into the building through the postbox. Traditionally, public buildings, residential buildings, kindergartens, nurseries, and other buildings have undergone exterior renovation as needed to extend their lifespan. Renovations allow the exterior walls, floors, and other surfaces of the building to be replaced with new exterior materials, creating a different environment than before. Furthermore, in recent years, a construction method has become known in which a fluorine-treated surface material is attached to the surface of a building's exterior structure, which has a door surface made of vinyl chloride sheeting and steel plate, to create a wall surface. The inventor previously invented an interior construction method using a sheet that can be easily constructed in a short time (see Patent Document 1). This method involves preparing an interior construction film made of a synthetic resin sheet and a magnetic sheet, and a base made of a magnetic material, determining areas on the ceiling, floor, or wall of a building where the interior construction will be applied, and attaching the interior construction film to the base formed on the surface of the area where the interior construction will be applied by magnetic force.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-227783 Summary of the Invention [Problem to be solved by the invention]
[0004] Traditionally, when renovating a building, the surface of the door would be replaced with new exterior material to create a different environment from before, but it took time to prepare the paint and other processes to adapt the exposed post slot on the door surface to the new environment. The present invention has been made in view of the above circumstances, and provides a mailbox repair sheet that can quickly and accurately repair the surface of a mailbox attached to a door of a building during renovation. [Means for solving the problem]
[0005] The mailbox repair sheet of the present invention is composed of a sheet for repairing the mailbox surface of a mailbox installed on the door of a building to be renovated, a transparent surface laminate film with a weak adhesive applied to the back side to protect the surface of the mailbox surface repair sheet, an adhesive layer for adhering the mailbox surface repair sheet to the mailbox surface, and a protective paper sheet that supports the adhesive layer adhered to the mailbox surface repair sheet, and is characterized in that the mailbox surface is formed after the protective paper sheet is peeled off from the mailbox surface repair sheet. The weak adhesive has weak adhesiveness, and after forming the post opening surface as described above, the surface laminating film can be easily peeled off and removed from the sheet that repairs the post opening surface. [Effects of the Invention]
[0006] The present invention allows for quick and accurate repairs to be made to the surface of a mailbox provided on a door of a building using a mailbox repair sheet when the building is renovated, for example. The surface laminating film is peeled off and removed from the sheet after forming the post opening surface with the sheet for repairing the post opening surface, but because it is transparent, it is easy to position the sheet at the target during repair. [Brief explanation of the drawings]
[0007] [Figure 1] FIG. 2 is a plan view of the post repair sheet according to the first embodiment. [Figure 2] A process diagram for applying the post repair sheet shown in Figure 1 to a door. DETAILED DESCRIPTION OF THE INVENTION
[0008] Hereinafter, the embodiments of the present invention will be described with reference to examples. [Example]
[0009] The mailbox repair sheet of Figure 1 explained in paragraph 0005 has sheet 1 (consisting of sheets 11 and 12) for repairing the mailbox surface, a transparent, weakly adhesive laminate film attached to its front surface, and an adhesive layer formed on its back surface for adhering to the surface of mailbox 20 exposed on the surface of door 10. Furthermore, sheet 1 for repairing the mailbox surface is provided with a protective paper sheet 2 that integrally supports the adhesive layer. Then, this sheet 1 for repairing the mailbox surface is used to repair the mailbox surface attached to the door of the building to be remade. The post repair sheet is attached to the surface of the post opening 20 after peeling off the protective paper sheet 2 from the sheet 1 for repairing the post opening surface, thereby forming the post surface with a new exterior material. After repairing the surface of the post, the laminate film is peeled off and removed from the sheet 1 for repairing the post opening surface, which is made up of sheets 11 and 12, to complete the repair.
[0010] Figure 2 explains the process for repairing the surface of a mailbox. First, peel off the protective paper sheet 2 attached to the sheet 1 used to repair the mailbox surface. Then, using a special scrubber, press a laminate film onto the mailbox surface to fit the shape of the mailbox. Then, peel off the laminate film to complete the post repair. The laminate film is transparent, making it easy to align it with the target post. It also has a weak adhesive, making it easy to peel off from the post repair sheet, facilitating work. It also has many advantages, such as being pre-cut to actual size, eliminating the need to trim excess material and eliminating unnecessary work. [Explanation of symbols]
