<< Embodiment 1 >>
<Summary of Embodiment 1>

This embodiment is a vibration-absorbing sheet that contains a phosphorescent phosphor in an elastic material. As shown in FIG. 1, the vibration-absorbing sheet (0101) of the present embodiment is installed under furniture (0102) arranged indoors. It is configured to emit light when it becomes dark at night, and the position of furniture etc. can be specified even in the dark.
<Configuration of Embodiment 1>

  The vibration-absorbing sheet of the present embodiment contains a phosphorescent phosphor in an elastic material, and has a first surface that should be in contact with the floor surface and a second surface that should be in contact with the bottom surface of the furniture disposed indoors. FIG. 2 shows a conceptual diagram of the vibration absorbing sheet of the present embodiment. The vibration-absorbing sheet of this embodiment has a first surface (0201) in contact with the floor surface and a second surface (0202) in contact with the bottom surface of furniture or the like. As shown in FIGS. 2A to 2D, the shape of the vibration-absorbing sheet of the present embodiment is changed according to the installation location and application, such as a square or a triangle, as well as a circle.

  The “elastic material” is a material having elasticity such as an elastomer material. Examples thereof include thermoplastic elastomers such as styrene, urethane, olefin, ester and amide. In particular, styrene thermoplastic elastomers are excellent in vibration absorption because of their low hardness, and are suitable for vibration absorbing sheets. Further, these elastomer materials are preferably transparent or translucent so as not to prevent light emission of a phosphorescent phosphor described later.

  By adding a softener (plasticizer) to these elastomer materials, the vibration damping performance is enhanced. Examples of the softener include mineral oil-based (paraffinic oil, naphthenic oil, aroma-based oil), vegetable oil-based, synthetic oil-based resins and rubber softeners. These softeners may be used alone or in combination of a plurality of types depending on the type of elastomer material of the vibration-absorbing sheet and the desired hardness. In addition, when a large amount of a softening agent is blended with the ester-based thermoplastic elastomer, not only the vibration absorption performance is increased, but also the surface is tacky. This adhesion improves the adhesion between the furniture and the floor surface, and it is also possible to suppress the movement of the furniture when vibration occurs.

  Unlike phosphors and fluorescent pigments, which require a light source when emitting light, “phosphorescent phosphors” store indoor lighting and sunlight light energy internally, and use the stored light energy in the dark. It is a thing that emits light for a long time, and it is a thing that repeats phosphorescence and light emission semipermanently. As the phosphorescent phosphor, a material having a long light emission time and excellent durability and a material containing no radioactive substance are preferable. Examples of the phosphorescent phosphor include metal aluminates such as strontium aluminate, strontium silicon aluminate, and calcium aluminate. The compounding amount of the phosphorescent phosphor is blended with the phosphorescent phosphor having a weight ratio of 2 to 50 with respect to the elastomer material 100. A weight ratio of 2 to 30 is particularly preferable. When the weight ratio is 2 or less, the light emission luminance is insufficient and the visibility in the darkness is deteriorated. On the other hand, when the weight ratio is 50 or more, the vibration absorption performance is lowered, and there is a possibility that the vibration absorption sheet does not function.

  In addition to blending the softener and the phosphorescent phosphor with the elastomer material, various fillers and various additives for improving the adhesiveness of the surface may be blended as necessary.

  The “first surface” and the “second surface” are a surface that is in contact with the floor surface and a surface that is in contact with the bottom surface of the furniture disposed in the room. FIG. 3 shows a perspective view of the vibration absorbing sheet of the present embodiment. The first surface (0301) and the second surface (0302) are formed as flat surfaces as shown in (a) or grooves (0303) of various shapes on the surface as anti-slip as shown in (b). You may do it. Further, the first surface and the second surface are not necessarily flat surfaces, and may be configured as substantially curved surfaces as shown in (c). The shapes of the first surface and the second surface may be only the first surface or the second surface, the both surfaces may be the same shape, or different shapes on the first surface and the second surface. It may be. In addition, when the first surface and the second surface have exactly the same shape, the first surface may be used as a surface contacting the furniture bottom surface, and the second surface may be used as a surface contacting the floor surface.

FIG. 4 shows a conceptual cross-sectional view of the vibration absorbing sheet of the present embodiment. As shown in (a), the first surface (0401) and the second surface (0402) may have the same size, or may have different sizes as in (b) and (c). .
