<Embodiment 1>

<Outline of Embodiment 1>

The marking tool of the present embodiment is a marking tool in which a transparent plano-convex lens made of silicone resin or elastic silicone rubber is bonded with a silicone gel film on a base portion of a substantially conical base, and has excellent weather resistance against ultraviolet rays and the like. There is.
<Embodiment 1 Configuration>

FIG. 1 is a diagram for explaining an outline of the configuration of the marking tool of the first embodiment, and is shown in a state of a perspective view in which the components are separated. As shown in this figure, the marking tool of the present embodiment has a base (0101), a reflective material (0102), a silicone gel film (0103), and a plano-convex lens (0104).
<Explanation of Embodiment 1 Configuration>
<Explanation of Embodiment 1 Configuration: Base>

The base is made of a truncated metal material. Since it is installed on roads, it is not only a strong material that does not easily deform when trampled by pedestrians, but also withstands temperature differences between seasons and day and night, and is resistant to corrosion by rainwater and acidic substances contained in exhaust gas. Must also be strong. In addition, since it is familiar to people (children) and pets such as dogs and cats, it is required that no toxicity occurs. In addition, for example, stainless steel, aluminum, aluminum alloy, copper, copper alloy, etc. are suitable in consideration of cost, maintainability, workability, decorativeness, specific strength, characteristics such as electromagnetic wave and heat reflection, and the like. ..

The top surface of the base (FIG. 1: 0105) is a horizontal flat surface because it is a surface that serves as a pedestal for the plano-convex lens. Further, since the plano-convex lens is adhered by the silicone gel film, the surface must be a smooth surface without roughness.

In addition, since it has a conical trapezoidal shape, it becomes wider toward the bottom, so stable fixation can be expected. For example, incident light from the headlight of an automobile is incident from slightly diagonally above the marking tool. It is expected that the incident angle of the incident light will be close to the side surface of the base, which has the effect of increasing the brightness of the reflected light due to the retroreflection by the reflective material described later that enters the driver's eyes. In addition, since there is no bias in a specific direction on the side surface, there are no restrictions on the direction in which the marking tool is installed.
<Explanation of the first embodiment: Reflective material>

The reflection by the reflector placed on the side of the truncated cone of the base must be a retroreflective reflection that reflects the light emitted from the headlight of a car or a bicycle, which is a light source at night, in the direction parallel to and in the opposite direction to the light source. It doesn't become. As a result, the driver of a car or a bicycle can return the reflected light of the light emitted by himself / herself to himself / herself without waste. For retroreflective reflection, a large number of very small (for example, about several tens to 100 μm in diameter) high refractive index glass bead spheres are uniformly mixed and arranged in a resin or paint, and a reflective layer (for example, aluminum) is placed near the lower side thereof. It can be done by surrounding it with a vapor-deposited layer, etc.). That is, the incident light forms a focal layer that focuses on the vicinity of the lower half of the transparent glass bead sphere due to the lens effect of the glass bead sphere having a high refractive index. Here, the incident light is reflected by the reflective layer surrounding the focal layer, and the reflected light passes through the focal layer again, re-enters the glass bead sphere, and refracts, and as a result, finally becomes almost the same as the incident light from the light source. It goes in the direction of the light source in parallel and in the opposite direction. Such glass bead type reflectors include an exposed lens type in which a spherical lens is exposed, an enclosed lens type in which a resin is placed on top of the spherical lens, and a capsule lens type in which an air layer is provided between the spherical lens and the resin film. .. Normally, the incident light is white light such as a car headlight, but by arranging a colorant on the film or focal layer that covers the surface of the glass bead sphere, the reflected light has the spectral transmittance characteristics of the colorant. It becomes colored light according to.

There is also a prism lens type retroreflective material (soft or hard) that uses a prism shaped like a right-angled triangular pyramid and has high reflection performance even when light is incident from various angles. Currently, the mainstream is a capsule prism type reflector which has excellent properties of high brightness and high durability. This is a reflective material in which only the portions contributing to the reflection are integrated and arranged by using the full cube corner reflective element, and it is preferable to use it as the reflective material of the marking tool. For example, 3M's glass bead-type high-brightness reflective sheet has about twice the reflective brightness of the conventional capsule lens-type reflective sheet, greatly increases surface strength, is resistant to scratching, and has excellent wide-angle characteristics. Therefore, it is said that it can be clearly seen even from an oblique direction and has the durability to maintain the initial reflection performance for a long period of time. Further, since glass does not deteriorate with ultraviolet rays, it is suitable as a material for the retroreflective sheet adopted by the present invention. Alternatively, it may be a retroreflective sheet using a transparent epoxy material or the like having good weather resistance.

The JIS standard (JIS Z9117: 2011) regarding the durability of such a retroreflective material maintains 80% of the initial brightness even when exposed to the south surface outdoors for 10 years, and the hue is a predetermined chromaticity coordinate. It is supposed to fit within the frame.
<Explanation of Embodiment 1: Silicone gel film>

Silicone gel film has excellent adhesiveness and adhesiveness as properties that it becomes a gel after curing, in addition to properties such as weather resistance, heat resistance / cold resistance, corrosion resistance, electrical insulation, and transparency peculiar to silicone. .. A silicone gel film is placed and attached between the bottom of a plano-convex lens made of silicone material and the top surface of the truncated cone of the base. Since the plano-convex lens and the silicone gel film are common materials, the affinity is high, and the silicone gel film flexibly follows the thermal expansion and contraction of the plano-convex lens, and the peeling of the adhered portion can be avoided.
<Explanation of Embodiment 1: Plano-convex lens>

A "planar convex lens" is a convex lens having a flat bottom surface. When the bottom surface is flat, it becomes easy to stably hold the plano-convex lens by making the top surface of the truncated cone-shaped base flat. It is conceivable to hold the convex lens in a shape other than the flat surface, but it is difficult to design and manufacture, so it is most efficient to hold the plano-convex lens using the flat surface.

As shown in FIG. 2, the plano-convex lens (0202) is configured so that the bottom portion of the convex lens is a flat surface and the peripheral portion thereof has a circumferential surface portion (0204) parallel to the optical axis (0201) of the plano-convex lens. May be good. On the silicone gel film (0207) arranged on the top surface of the truncated cone of the base, the edge (0203) forming the circumferential surface of the plano-convex lens is the inner wall of the circumferential wall of the top surface of the truncated cone of the base (0203). It is preferable to configure it so that it is arranged along 0206). For example, when a light emitting member or a phosphorescent member is arranged on the top surface of the truncated cone over the entire surface (excluding the wall surface portion), it is preferable that the light emitted from the entire surface is evenly accommodated in the plano-convex lens. In that case, if the structure has no edge, only a small amount of light at the outermost periphery of the light emitting member or the phosphorescent member is accommodated in the plano-convex lens, and the efficiency is not very good. Therefore, the portion is provided with an edge to give it a thickness so that the amount of light spilled at the outermost circumference of the plano-convex lens is reduced. Furthermore, when this plano-convex lens is made of flexible, for example, silicone rubber, if the outermost circumference becomes too thin, the strength will be weakened and it will be easily damaged by external force, so it is better to have a certain thickness. It is advantageous. Further, when the outermost edge of the plano-convex lens is protected by the wall surface provided on the outermost outer circumference of the upper surface of the base, the protective effect is further enhanced, which is preferable.

In addition, by using a silicone material for the plano-convex lens, it has excellent properties as a lens such as weather resistance, heat resistance / cold resistance, corrosion resistance, electrical insulation, and transparency peculiar to silicone. Therefore, there is little deterioration such as white turbidity due to ultraviolet rays, etc., and it has excellent durability.

As shown in FIG. 3, when the plano-convex lens (0303) is used, the incident angle of the incident light (0301) from the outside: S ₁ (0302) is the incident light (0304) from the outside when the plano-convex lens is not used. ): The angle of incidence _{is wider than that of S 2} (0305), which is advantageous in accumulating the incident light described later. Further, as shown in FIG. 4, when the plano-convex lens (0403) is used, the reflection angle of the light reflected to the outside (0401): T ₁ (0402) is the reflected light from the outside when the plano-convex lens is not used. Reflection angle of (0404): Since _{it is wider than T 2} (0405), the irradiation angle of light to the outside is wide, which is effective in reducing the blind spot range required for the marking tool.
<Simple description of the effect of Embodiment 1>

According to the present embodiment, it is possible to provide an integrated marking tool having excellent adhesion between the base and the transparent plano-convex lens. Further, a transparent plano-convex lens made of silicone resin or elastic silicone rubber can have an advantageous property that it is not easily deteriorated by ultraviolet rays or the like.

<Embodiment 2>

<Outline of Embodiment 2>

The marking tool of the present embodiment is based on the above-described first embodiment, and is further characterized in that the silicone gel film is widely arranged on the top surface of the base.
<Embodiment 2 Configuration>

The silicone gel film in the marking tool of the present embodiment is a circular film, and the outermost peripheral edge is arranged so as to be near the outermost peripheral edge of the top surface of the truncated cone of the base.
<Explanation of Embodiment 2 Configuration>
<Explanation of Embodiment 2: Arrangement of film>

Originally, the silicone gel film is for attaching a plano-convex lens made of a base and a silicone material, and if only suitable for the purpose, one or more divisions are made on a part of the top surface of the truncated cone of the base. It is enough to place it in. However, by making the silicone gel film circular and arranging the outermost periphery thereof in the vicinity of the outermost periphery of the top surface of the truncated cone of the base, the silicone gel film is uniformly in contact with the bottom of the plano-convex lens. As a result, there is no intervening part such as air or moisture between the bottom surface of the plano-convex lens and the top surface of the truncated cone of the base, and in addition to the effect of enhancing the reflection effect, the top surface of the truncated cone surface of the base and the bottom surface of the truncated cone lens Prevent deterioration.
<Brief description of the effect of the second embodiment>

The marking tool of the present embodiment can be used as a marking tool having excellent durability to prevent deterioration.

<Embodiment 3>

<Outline of Embodiment 3>

The marking tool of the present embodiment is based on the above-described first or second embodiment, and further includes one or more of a flat reflector, a flat phosphorescent member, and a flat self-luminous member under the silicone gel film of the base. It is characterized by that.
<Structure 3 of Embodiment>

As shown in FIG. 5, the lower layer (0502) of the base silicone gel film (0501) in the marking tool of the present embodiment is provided with any one or more of a flat reflector, a flat phosphorescent member, and a flat autofluorescent member. There is.
<Explanation of Embodiment 3 Configuration>
<Explanation of Embodiment 3: Planar Reflective Material>

The flat reflector is underneath the silicone gel film and is placed flat on the top surface of the truncated cone of the base, for example, by spraying titanium oxide or affixing the titanium oxide film. Reflection by the flat reflector is similar to the reflector placed on the side surface of the truncated cone of the base, in which the light emitted from the headlight of a car or a bicycle, which is a light source at night, is parallel to and opposite to the light source direction. Must be a retroreflective reflection on. The plano-convex lens attached on the silicone gel film diffuses the light over a wide angle and irradiates it to the outside. As a result, the reflected light of the light emitted from the headlight of the automobile or bicycle not only returns in the direction parallel to and in the opposite direction to the light source, but also brings a part of the brightness to the peripheral part, so that the blind spot required for the marking tool is required. It has the effect of reducing the range. The color of the flat reflector is preferably white because of its high reflection efficiency.
<Explanation of Embodiment 3: Planar phosphorescent member>

The planar phosphorescent member is underneath the silicone gel film and is arranged planarly on the top surface of the truncated cone of the base. The phosphorescent member stores light energy radiated from the outside and radiates a certain amount of the energy to the outside as light emission. The differential energy is stored in the phosphorescent member and has the physical property of emitting light even when the light irradiation from the outside is stopped. Generally, the phosphorescent member has problems in its brightness and afterglow time, but it is advantageous for the phosphorescent function because the light is collected in a wide angle by the plano-convex lens attached on the silicone gel film. is there. On the contrary, since the plano-convex lens irradiates light at a wide angle, it has the effect of widely notifying the existence of the marking tool by bringing the brightness to the peripheral portion.
<Explanation of the configuration of the third embodiment: a flat self-luminous member>

The flat self-luminous member is located under the silicone gel film and is arranged in a flat unit-embedded manner on the top surface of the truncated cone of the base. There are a single-sided light emitting member that emits light only on one side and a double-sided light emitting member that emits light on both sides. The single-sided light emitting member has a higher brightness on the light emitting surface than the double-sided light emitting member. The flat self-luminous member is, for example, an LED or an organic EL that automatically lights up at night, and requires external power, but the required power is small and excellent in durability, so that it is bright for a long time. It is used in the marking tool that you want to hold. The plano-convex lens attached on the silicone gel film diffuses the light over a wide angle and irradiates it to the outside. As a result, the reflected light of the light emitted from the headlight of the automobile or bicycle not only returns in the direction parallel to and in the opposite direction to the light source, but also brings a part of the brightness to the peripheral part, so that the blind spot required for the marking tool is required. It has the effect of reducing the range.
<Explanation of the configuration of Embodiment 3: Combination of a flat self-luminous member, a flat phosphorescent member, and a flat reflector>

Various effects can be obtained by combining any two or more of the above-mentioned plane reflector, translucent plane phosphorescent member, opaque plane phosphorescent member, transparent plane self-luminous member, and semitransparent self-luminous member. Here, the plane reflector can be used only for the lowermost layer, and the plane phosphorescent member and / and the plane self-luminous member in the case of being the upper layer have the property of light translucency (transparent, translucent). In addition, in the combination of any two or more of the members including the above-mentioned flat reflector, the members are attached to each other via a silicone gel film or a silicone gel to avoid peeling of the attached portion and to have brightness. It pushes out air that causes deterioration and prevents its contamination.

≪The upper layer is a transparent double-sided self-luminous member and the lower layer is an opaque phosphorescent member.

In the daytime, the upper layer is a transparent double-sided self-luminous member, and since sunlight is transmitted, the sunlight is efficiently absorbed by the opaque phosphorescent member in the lower layer, and the light is emitted by the phosphorescence at night. When the transparent double-sided autofluorescent member emits light at night, the light from the upper surface of this layer is irradiated to the road or the like through the plano-convex lens, the light from the lower surface of this layer is absorbed by the opaque phosphorescent member, and the transparent double-sided autofluorescent member of the upper layer is used. Even when the light emission of the light emitting member is interrupted, the light is emitted by the phosphorescence accumulated by the light emission of the transparent double-sided self-light emitting member before that. Therefore, even if the transparent double-sided self-luminous member does not emit light during the night, it can be used as a road marking tool that is bright all night only by emitting light intermittently.

≪The upper layer is a transparent double-sided self-luminous member, the lower layer is a semi-transparent double-sided phosphorescent member, and the lower layer is a combination of flat reflectors≫

In the upper transparent double-sided self-luminous member, the light emitted upward is emitted to the outside from the plano-convex lens, part of the light directed downward is accumulated in the phosphorescent member, and the other part is transmitted through the phosphorescent member. It is reflected by the plane reflecting material and contributes to the phosphorescence of the phosphorescent member again, or is transmitted through the phosphorescent member and further transmitted through the transparent flat self-luminous member and emitted from the plano-convex lens. That is, the waste of light energy is relatively small, and the energy consumption can be reduced because the electricity supply of the transparent double-sided self-luminous member is unnecessary overnight as in the above example.

≪The upper layer is a translucent flat phosphorescent member, the lower layer is a transparent double-sided flat autofluorescent member, and the lower layer is a combination of reflective materials≫

Since the upper layer is a translucent flat phosphorescent member, it can efficiently receive the energy of sunlight in the daytime, especially the solar energy from the plano-convex lens, and at night, it receives the light irradiation of the transparent double-sided flat self-luminous member in the lower layer. Since a part of the self-luminous light can be radiated from the plano-convex lens to the outside through the translucent phosphorescent layer, the brightness can be improved as compared with the case where the phosphorescent member simply irradiates the light at night. ..

≪Combination of semi-transparent flat phosphorescent member in the upper layer, transparent double-sided flat autofluorescent member in the lower layer, and opaque single-sided luminous phosphorescent member in the lower layer≫

In the above example, a single-sided light emitting and phosphorescent member is arranged in place of the lower layer reflecting member. The reflector in the above example may be in the bottom layer. The difference from the above example is that the single-sided light emitting and phosphorescent member is arranged at a position where the reflector is located. Instead of simply reflecting, light energy is stored in the phosphorescent member. Since energy is stored in the lower layer in addition to the energy storage efficiency of the translucent phosphorescent member in the uppermost layer, the energy storage efficiency can be improved as compared with the case where energy is stored in a single layer.
<Brief description of the effect of Embodiment 3>

By providing any one or more of a flat reflector, a flat phosphorescent member, and a flat autofluorescent member in the lower layer of the silicone gel film, the brightness of the marking tool can be improved.

<Explanation of Embodiment 7 Configuration>
<Explanation of the configuration of Embodiment 7: glass coating layer>

The glass coating layer has the effect of improving weather resistance and antifouling property by protecting the surface covered by the glass coating layer. Due to the affinity between glass and silicone materials, the effect lasts for a long time. The glass coating has a structure in which the entire surface of the plano-convex lens and the boundary between the plano-convex lens and its lower structure are covered with a layered member made of glass in order to protect the surface from scratches, water wetting and dust. Is.
