Abstract

PROBLEM TO BE SOLVED: To provide a luminous belt-like covering material and a covering structure using the same, which can be easily and surely covered along a bent surface or a curved surface, and excellent in durability.SOLUTION: A long size luminous belt-like covering material for covering a bent surface or a curved surface, is formed as a belt-like covering material 10 constituted so that an elastic modulus of a luminous area A is larger than an elastic modulus of a non-luminous area B, by forming a plurality of luminous areas A including a luminous agent while separating the non-luminous area B of not including the luminous agent along its longitudinal direction. Since the non-luminous area B of a small elastic modulus is easily deformed more than the luminous area A of a large elastic modulus, the belt-like covering material 10 can surely cover the bent surface or the curved surface while being easily deformed along the bent surface or the curved surface with the non-luminous area B as a starting point. A covering structure is constituted so that a plurality of luminous areas A of the belt-like covering material 10 for covering the bent surface or the curved surface exist on both-side surfaces of a bent part of the bent surface or the curved surface.

Description

  The present invention relates to a phosphorescent belt-like covering material and a covering structure using the same, and more specifically, a stair nosing part (corner part), a handrail such as a passage or a staircase, a protruding corner part or a entering corner part of a wall, and a width. The present invention relates to a luminous band-shaped covering material applied to trees, waist walls, doors, and the like, and a covering structure of a bent surface or a curved surface using the same.

  Conventionally, it has been known to apply a luminescent paint to the upper surface of a stair nosing part or a handrail, or to attach a synthetic resin band (non-slip) containing a fluorescent material to the upper surface of a stair nosing part. (For example, Patent Documents 1 and 2).

  By doing so, there is an advantage that safety is improved because the fluorescent light emitted from the fluorescent material of the luminous paint or the belt-shaped member can be moved up and down while confirming the presence of the stairs even in the dark.

However, when applying a luminescent coating, the coating is worn out in a relatively short period of time, which is problematic in terms of durability.
In addition, when using a band-shaped member containing a fluorescent substance, the band-shaped member is bent and stuck along the nose of the staircase at a substantially right angle, or the band-shaped member is bent while being bent along the curved surface of the handrail. There is a problem that it is difficult to wear.

  The present invention has been made under the circumstances described above, and the problem to be solved is durability that can be easily and reliably covered along a curved surface such as a stair nosing portion or a curved surface such as a handrail. An object of the present invention is to provide a light-storing belt-like covering material excellent in the above and a covering structure using the same.

  In order to solve the above problems, the phosphorescent belt-shaped coating material according to the present invention is a long phosphorescent belt-shaped coating material that covers a bent surface or a curved surface, and a phosphorescent agent is added along the longitudinal direction thereof. A plurality of luminous areas A containing a luminous agent are formed across a non-luminous area B that is not included, and the elastic modulus of the luminous area A is greater than the elastic modulus of the non-luminous area B.

Here, the phosphorescent region A and the non-light-accumulating region B are not regions on the surface of the belt-shaped covering material, but mean regions over the entire thickness of the belt-shaped covering material. In addition, the phosphorescent region A means a region containing the phosphorescent agent over the entire thickness of the belt-shaped covering material, but when a layer not containing the phosphorescent agent is formed immediately below the layer containing the phosphorescent agent. Means a region covering the entire thickness of the belt-like covering material in which both layers are combined.
The elastic modulus refers to a tensile elastic modulus measured based on JIS K 7161.

In the band-shaped covering material of the present invention, the elastic modulus of the luminous region A is 15 N / mm ² or less, and the ratio of the elastic modulus between the luminous region A and the non-luminous region B (non-luminous region B / luminous region A) is 0. .65 to 0.95 is desirable.
And the thickness of the luminous area A is larger than the thickness of the non-luminescent area B, and the ratio of the thickness of the luminous area A and the non-luminescent area B (thickness of the non-luminescent area B / thickness of the luminous area A). Is preferably 0.3 to 0.8. In addition, the thickness means the thickness of the thin portion when the thick portion and the thin portion exist in the regions A and B.
Moreover, in the strip | belt-shaped coating | covering material of this invention, the 1st small groove is formed along the longitudinal direction on the surface or back surface of the non-light-accumulating area | region B, or the 2nd along the longitudinal direction is formed on the surface of the phosphorescent area | region A. It is also desirable that a small groove is formed.

  On the other hand, the covering structure according to the present invention is a structure in which a bent surface or a curved surface is covered with the above-described phosphorescent band-shaped covering material, and a plurality of light storage regions A of the band-shaped covering material are surfaces on both sides of the bent portion of the bent surface. It exists on the top or the curved surface.

Like the phosphorescent belt-like covering material according to the present invention, a plurality of phosphorescent regions A having a larger elastic modulus than the elastic modulus of the non-luminous region B are formed along the longitudinal direction with the non-luminous region B separated. When the bent or curved surface is covered with this belt-shaped covering material, the non-light-storing region B having a low elastic modulus is more easily deformed than the light-storing region A having a large elastic modulus. The band-shaped covering material is easily deformed along the bent surface or the curved surface, and the bent surface or the curved surface can be reliably covered.
And since the phosphorescent agent contained in the phosphorescent region A is excited by sunlight or illumination light and emits phosphorescence, as in the coating structure of the present invention, this belt-shaped coating material covers the bent surface or the curved surface, When a plurality of phosphorescent regions A are present on the surfaces on both sides of the bent portion of the bent surface or on the curved surface, each phosphorescent region A emits light when the surroundings become dark, thereby causing the bent surface or the curved surface from both sides. The presence of the surface can be visually recognized.

In particular, the elastic modulus of the luminous area A is 15 N / mm ² or less, and the ratio of the elastic modulus between the luminous area A and the non-luminous area B (non-luminous area B / luminous area A) is 0.65 to 0.95. In a certain belt-shaped covering material, the luminous region A has a certain degree of flexibility, and the difference in the degree of flexibility between the luminous region A and the non-luminous region B is relatively small, and the non-luminous region B is moderate. Therefore, when the curved surface is covered with this belt-shaped covering material, the belt-shaped covering material follows the curved surface and bends and deforms more easily, and the non-light-accumulating region B is more than necessary in the light-accumulating region A. It is possible to prevent the phenomenon that the side edge of the phosphorescent region A is lifted from the curved surface by being pulled.

  Further, the thickness of the luminous area A is larger than the thickness of the non-luminescent area B, and the ratio of the thickness of the luminous area A and the non-luminescent area B (thickness of the non-luminescent area B / thickness of the luminous area A). In the band-shaped coating material having a thickness of 0.3 to 0.8, the non-light-storing region B having a small thickness is more easily deformed. As a starting point, the belt-shaped covering material can be more easily deformed along the curved surface or the curved surface, and can be reliably coated.

  Further, the band-shaped covering material in which the first small groove is formed along the longitudinal direction on the front surface or the back surface of the non-light-accumulating region B is more easily bent or curved by the first small groove. It can deform | transform even more easily along a surface or a curved surface, and can coat | cover reliably.

  Furthermore, the band-shaped coating material in which the second small groove is formed along the longitudinal direction on the surface of the phosphorescent region A is easy to accumulate contaminants in the second small groove even if the contaminant adheres to the phosphorescent region A. The contamination of the entire surface of the phosphorescent region A can be reduced, whereby the phosphorescent agent contained in the phosphorescent region A can be excited efficiently to emit light efficiently.

  In addition, the coating structure of the present invention can reliably cover the phosphorescent band-shaped coating material of the present invention while deforming along the curved surface or curved surface, and the plurality of luminous regions A are on the surfaces on both sides of the bent portion of the curved surface. Or, since it exists on the curved surface, when the surroundings become dark, each phosphorescent region A emits light, and the presence of the bent surface or the curved surface can be visually recognized from both sides.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a plan view showing a luminous band-shaped covering material according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the band-shaped covering material, and FIG. 3 is an enlarged partial cross-sectional view of a central portion of the band-shaped covering material. FIG. 4 is an enlarged partial cross-sectional view of a portion where the phosphorescent region A of the band-shaped covering material is formed.

This phosphorescent band-shaped covering material 10 is according to a basic embodiment of the present invention, and as shown in FIGS. 1 and 2, the band-shaped central portion does not contain a phosphorescent agent in the center in the width direction. The non-light storage region B is formed along the longitudinal direction of the strip-shaped covering material 10. A plurality of (two) thin-band-shaped phosphorescent regions A, A containing a phosphorescent agent are formed along the longitudinal direction of the strip-shaped covering material 10 on both sides across the non-light-accumulating region B of the central portion. Further, on the further outer side of the phosphorescent regions A and A, strip-shaped non-luminous regions B and B not containing a phosphorescent agent are formed along the longitudinal direction of the strip-shaped covering material 10.
An adhesive layer 20 is provided on the back surface of the belt-shaped covering material 10, and the lower surface thereof is covered with a release paper 30.

The non-light-storing regions B, B, B in the width direction central part and both side edge parts of the belt-like covering material 10 are formed by the flexible non-light-storing layer 2 that does not contain a light-storing agent. It is an area that spans. On the other hand, the luminous areas A and A are areas covering the entire thickness of the belt-shaped covering material 10 formed by the flexible luminous layer 1 containing the luminous agent and the non-luminescent layer 2 immediately below it. The phosphorescent agent contained in the layer 1 is an area that is excited by sunlight or illumination light, emits phosphorescence when the surroundings become dark, and emits light with sufficiently visible brightness.
Of course, the non-light storage layer 2 directly below the light storage layer 1 may be omitted, and the light storage region A may be formed by the light storage layer 1 alone.

  The non-light storage layer 2 forming the non-light storage region B is formed of a flexible thermoplastic synthetic resin such as vinyl chloride resin or olefin resin, rubber, or the like, and also stores the light storage region A. The layer 1 is formed of a flexible thermoplastic synthetic resin such as a vinyl chloride resin or an olefin resin containing a phosphorescent agent, rubber, or the like.

  The phosphorescent agent contained in the phosphorescent layer 1 is a strontium aluminate-based phosphorescent agent having a long afterglow time, high afterglow luminance, good light resistance and weather resistance (for example, trade name [manufactured by Nemoto Special Chemical Co., Ltd.] N-nightlight ”and the like, and zinc sulfide-based phosphorescent agents are preferably used. The content of these phosphorescent agents is suitably 5 to 200 parts by mass with respect to 100 parts by mass of the thermoplastic synthetic resin or rubber so that the phosphorescent layer 1 emits light with a brightness that can be seen in the dark. .

  It is desirable to add a white pigment such as titanium oxide to the rear surface side (lower surface side) of the phosphorescent layer 1. When a white pigment is added in this way, the ultraviolet rays of sunlight and illumination light that have entered the phosphorescent layer 1 and were not used for excitation of the phosphorescent agent are reflected by the white pigment and effectively used for excitation of the phosphorescent agent. It becomes possible to increase the excitation efficiency of the phosphorescent agent, and the phosphorescence emitted from the phosphorescent agent to the back side of the phosphorescent layer 1 is reflected to the surface side by the white pigment, so that the emission luminance can also be increased. .

This belt-shaped covering material 10 has an elastic modulus (tensile elastic modulus measured based on JIS K 7161) of the luminous region A larger than that of the non-luminous region B. Specifically, the luminous region A The elastic modulus is 15 N / mm ² or less, and the ratio of the elastic modulus between the luminous area A and the non-luminous area B (non-luminous area B / luminous area A) is 0.65 to 0.95. Therefore, since the phosphorescent region A has a certain degree of flexibility, and the difference in the degree of flexibility between the phosphorescent region A and the non-luminescent region B is relatively small, the non-luminescent region B has an appropriate flexibility. When, for example, a curved surface is covered with the belt-shaped covering material 10, as shown in FIG. 7, the belt-shaped covering material 10 follows the curved surface 110 and easily bends and deforms in the width direction, so that the curved surface is surely curved without partially rising. The surface 110 can be coated. This is also apparent from the results of the effect confirmation test described later.

However, when the elastic modulus of the luminous region A exceeds 15 N / mm ² and the ratio of the elastic modulus between the luminous region A and the non-luminous region B (non-luminous region B / luminous region A) is less than 0.65. As shown in the results of the effect confirmation test described later and FIG. 8, both ends of the phosphorescent region A come to rise from the curved surface 110, and even when the elastic modulus of the phosphorescent region A is 15 N / mm ² or less, the elastic modulus If the ratio exceeds 0.95, the band-shaped covering material 10 is partially lifted from the curved surface, and particularly, both side edges of the band-shaped covering material 10 are considerably lifted, which is inappropriate in either case. .
The lower limit of the elastic modulus of the phosphorescent region A is 5N / mm ^2, becomes smaller than this, considerably reduces the overall modulus of the belt-shaped covering member 10, not suitable because the strength of the belt-shaped covering member 10 is insufficient is there.

  Adjustment of the elastic modulus of the non-light-accumulating region B is performed by selecting a material having an elastic modulus appropriate for the material forming the non-light-accumulating layer 2 or when the material forming the non-light-accumulating layer 2 is a vinyl chloride resin, for example. What is necessary is just to perform by increasing / decreasing content of the plasticizer contained in a composition, etc. Moreover, the adjustment of the elasticity modulus of the luminous region A may be performed similarly regarding the luminous layer 1, for example. If the material is vinyl chloride resin, the elastic modulus will decrease if the plasticizer content is increased, and the elastic modulus will increase if the phosphorescent agent content is increased. Can be done.

Moreover, this strip | belt-shaped coating | covering material 10 has the thickness of the luminous region A (thickness which added the luminous layer 1 and the non-luminescent layer 2 immediately under it) the thickness of the non-luminescent region B (thickness of the non-luminescent layer 2). ) And the ratio of the thickness of the luminous area A and the non-luminous area B (thickness of the non-luminous area B / thickness of the luminous area A) is 0.3 to 0.8. Specifically, the thickness of the luminous region A is about 0.1 to 5 mm, and the thickness of the non-luminous region B is about 0.08 to 4 mm. And the thickness of the phosphorescent layer 1 is set to about 0.1-3 mm including the case where the non-luminous layer 2 does not exist immediately below.
In addition, although this strip | belt-shaped coating | covering material 10 has constant thickness in the luminous area A and the non-luminous area | region B, when the thick part and the thin part exist like the non-luminous storage area | region B of the strip | belt-shaped coating | covering material 11 mentioned later The thickness in means the thickness of the thin part.

  If the luminous area A and the non-luminous area B have the above thickness, the non-luminous area B having a small thickness is more easily deformed. Therefore, the belt-shaped covering material 10 covers the bent surface or the curved surface. At this time, the band-shaped covering material 10 can be more easily deformed along the curved surface or the curved surface starting from the non-light-accumulating region B, and can be reliably coated without being lifted.

As shown in FIG. 3, the first small groove 3 having a V-shaped cross section along the center line is formed on the surface of the non-light-storing layer 2 in the non-light-storing region B in the central portion in the width direction of the band-shaped covering material 10. It is formed over the entire length of the non-light storage region B. Moreover, although not shown in figure, the same 1st small groove is formed over the full length also in the surface of the non-light-accumulating layer 2 and 2 in the non-light-accumulating area | regions B and B of the right-and-left both sides edge of this strip | belt-shaped coating | covering material 10. ing.
Of course, a plurality of the first small grooves 3 may be formed in each non-light storage region B. Further, the cross-sectional shape of the small groove 3 is not limited to the V shape, and may be a U shape or other desired shapes.

  As described above, when the first small groove 3 is formed in the non-light-storing region B in the central portion of the belt-shaped covering material 10 or the non-light-storing regions B on the left and right side edges, these non-light-storing regions B are formed in the first small groove. 3 makes it easier to bend or bend, so that the belt-like covering material 10 can be more easily deformed along the bent or curved surface and reliably covered.

Further, as shown in FIG. 4, a plurality of (four) second small grooves 4 having a V-shaped cross section are formed over the entire length of the phosphorescent region A on the surface of the phosphorescent layer 1 forming the phosphorescent region A. Has been. The second small groove 4 is formed so that contaminants adhering to the surface of the phosphorescent layer 1 are likely to be collected in the small groove 4, and the contaminant is accumulated in the second small groove 4 to thereby store the phosphorescent region. Dirt on the entire surface of the phosphorescent layer 1 of A can be reduced, the phosphorescent agent contained in the phosphorescent layer 1 can be efficiently excited by sunlight or illumination light, and can emit light with sufficient brightness when the surroundings become dark It is intended.
The cross-sectional shape of the second small groove 4 is not limited to the V-shape, and can be a desired cross-sectional shape in which contaminants easily accumulate. Moreover, the number of the small grooves 4 can also be made into a desired number.

Although the dimension of each part of this strip | belt-shaped coating | covering material 10 is not specifically limited, It is as follows when a preferable dimension is illustrated.
That is, the width of the belt-shaped covering material 10 is 20 to 200 mm, the length is 0.5 to 50 m, the width of the phosphorescent region A is 2 to 50 mm, the thickness is 0.1 to 5 mm, and the width of the phosphorescent layer 1 is 2 to 50 mm. The thickness is 0.1 to 3 mm, the width of the non-light storage region B is 2 to 50 mm, and the thickness is 0.08 to 4 mm.

Such a strip | belt-shaped coating | covering material 10 can be manufactured with the following method, for example.
That is, by adopting a coextrusion molding method, a flexible thermoplastic synthetic resin that does not contain a phosphorescent agent is extruded in the width dimension of the belt-shaped coating material 10 to form the non-luminous phosphor layer 2, and at the same time, a flexibility that contains the phosphorescent agent. Can be manufactured by forming the phosphorescent layer 1 by superimposing a certain thermoplastic synthetic resin on the upper surface on both sides of the central portion of the non-luminous phosphor layer 2 and coextruding it in the width dimension of the phosphorescent region A.
In addition, a flexible thermoplastic synthetic resin that does not contain a phosphorescent agent and a flexible thermoplastic synthetic resin that contains a phosphorescent agent are simultaneously injection-molded (two-color injection molding), or no phosphorescent agent is contained. After the non-light-storing layer 2 of the belt-shaped covering material is formed from a thermoplastic synthetic resin, the light-storing layer 1 can be formed by a resin paint containing a light-storing agent.

As shown in FIGS. 3 and 4, the adhesive layer 20 provided on the back surface of the belt-shaped covering material 10 is an adhesive having a three-layer structure in which adhesive layers 22 and 22 are laminated on both surfaces of a flexible foam layer 21. Is a layer. The adhesive layer 20 is adhered to the back surface of the non-light-storing layer 2 of the strip-shaped covering material 10 by the upper adhesive layer 22, and the lower adhesive layer 22 is covered with the release paper 30. .
The adhesive layer 22 is a layer having a thickness of 0.02 to 1.5 mm made of an adhesive such as acrylic, rubber, or urethane, or an adhesive such as urethane, epoxy, or acrylic. The foam layer 21 is a layer having a thickness of 0.1 to 5 mm made of a flexible resin foam such as polyethylene, polypropylene, and acrylic.
The width dimension of the adhesive layer 20 is preferably the same as or slightly smaller than the width dimension of the belt-shaped covering material 10.

  When the adhesive layer 20 having such a three-layer structure having the flexible foamed layer 21 is provided on the back surface of the strip-shaped covering material 10, the release paper 30 is peeled off so that the strip-shaped covering material 10 is bent or curved. When sticking, even if there are some irregularities on the bent surface or curved surface, the flexible foamed layer 21 can absorb the irregularities and stick, so the reliability of the sticking is improved.

  Of course, the adhesive layer 20 and the release paper 30 may be omitted, and the belt-shaped covering material 10 may be applied by being attached to a bent surface or a curved surface with an adhesive or an adhesive.

FIG. 5 is a perspective view exemplifying a portion to which the belt-shaped covering material 10 is applied. FIG. 5A is a diagram illustrating a case where the bent surface of the stair nose 51 a of the stair 51 is bent at a substantially right angle with the belt-shaped covering material 10. FIG. 6B shows a state where the bent surface bent at a right angle at the upper end of the side wall 52 of the staircase is covered with the belt-shaped covering material 10. (C) shows a belt-shaped bent surface extending from the baseboard 55 to the floor surface 56 at the lower end of the wall surface when the bent surfaces of the protruding corner portion 53a and the inlet corner portion 53b of the wall surface 53 are covered with the band-shaped covering materials 10 and 10. A portion covered with the covering material 10 and a portion where the arcuate surface (curved surface) of the round bar-shaped handrail 54 is covered with the belt-like covering material 10 are shown.
These are only a few examples of the places where the belt-like covering material 10 is applied, and the belt-like covering material 10 of the present invention can be applied to bent and curved surfaces at various places inside and outside the above.

  FIG. 6 is a cross-sectional view showing an embodiment of the coating structure of the present invention coated with the band-shaped coating material.

  This covering structure is obtained by covering the bent surface 100 bent at a right angle of the nose portion 51a of the staircase 51 with the above-described band-shaped covering material 10 and stripping the release paper to expose the adhesive layer 20. The non-light-storing region B at the center portion in the width direction of 10 is lightly attached to the bent portion at the tip of the nose portion 51a for positioning, and the belt-like covering material 10 has a low elastic modulus and is easily deformed along the bent surface 100. The light storage region B is bent and deformed at a right angle and is strongly pressed to cover the bent surface 100, and the light storage regions A and A exist on both sides of the bent portion of the bent surface 100, that is, on the upper surface and the front surface of the nose portion 51a. It is what you do.

As described above, this covering structure is formed by bending the band-shaped covering material 10 at a right angle in the central portion in the width direction of the band-shaped covering material 10 and in a non-light-storing region B where deformation is easy and deformation is pasted. In addition, since the first small groove 3 is also formed in the non-light-accumulating region B and the deformation is further facilitated, the band-shaped covering material 10 can be reliably covered without being lifted along the bent surface 100.
Since the phosphorescent regions A and A exist on both surfaces of the bent portion of the bent surface 100 (the upper surface and the front surface of the nose portion 51a), when the surroundings become dark, the phosphorescent regions A and A emit light and the nose portion 51a. The presence of the bent surface can be viewed from above and from the front. Therefore, when going up the stairs 51, the light emission from the phosphorescent region A on the front surface of the nose portion 51a is visually recognized. When going down the stairs 51, the light emission from the phosphorescent region A on the upper surface of the nose portion 51a is visually recognized. 51 can be moved up and down safely.

  FIG. 7 is a cross-sectional view showing another embodiment of the coating structure of the present invention coated with the belt-shaped coating material.

  In this covering structure, the strip-shaped covering material 10 from which the release paper is peeled and the adhesive layer 20 is exposed is curved and deformed in the width direction along the curved surface 110 (arc surface) of the round bar-shaped handrail 54, The front surface portion is covered from the upper surface portion of the curved surface 110 by strongly pressing so that the phosphorescent regions A and A are present at the front portion of the curved surface 110 and the upper portion of the front surface portion.

As described above, the belt-shaped covering material 10 used for this covering structure has an elastic modulus of the luminous region A of 15 N / mm ² or less, and the ratio of the elastic modulus between the luminous region A and the non-luminescent region B (non-luminescent region B / Since the phosphorescent region A) is 0.65 to 0.95, both side edges of the phosphorescent region A are not lifted as shown in FIG. As shown in the figure, the belt-like covering material 10 is easily bent and deformed in the width direction along the curved surface 110, and can reliably cover the curved surface 110 without being lifted. And the phosphorescent regions A and A are curved by the handrail 54. Since there are two parallel surfaces on the surface 110, the presence of the handrail 54 can be surely recognized when the surroundings become dark and light is emitted, and the contaminants enter the phosphorescent regions A and A by rubbing the hand. Even if attached, formed in phosphorescent areas A and A Since the second contaminants into small grooves 4 that are phosphorescent regions A, contamination of the entire surface of the A is reduced accumulated, it is also possible to suppress a reduction in luminance due to contamination.

  FIG. 9 is a plan view showing a phosphorescent band covering according to another embodiment of the present invention, FIG. 10 is a front view of the band covering, FIG. 11 is a right side view of the band covering, and FIG. FIG. 13 is an enlarged partial front view of the central portion of the band-shaped covering material, FIG. 14 is an enlarged partial front view of the left edge portion of the band-shaped covering material, and FIG. 15 is a phosphorescent region of the band-shaped covering material. It is an enlarged partial front view of the part which formed A, Comprising: This strip | belt-shaped coating | covering material is a elongate coating | covering material which continues up and down in FIG.

  This strip-shaped covering material 11 is further improved in design and practicality. As shown in FIGS. 9 and 10, the strip-shaped covering material 11 is formed on both side ends of the non-light-storing layer 2 constituting the non-light-storing region B in the center portion in the width direction. Are formed along the longitudinal direction with first ridges 5 and 5 that are slightly higher than the upper surfaces of the phosphorescent layers 1 and 1 in the phosphorescent regions A and A. Then, the side edges of the non-light-storing layer 2 constituting the non-light-storing regions B and B of the side edge portions of the belt-shaped covering material 11 are respectively symmetric with the first ridge 5 on the side edges on the side of the light-storing region A. Of the non-light-storing layer 2, and a second ridge 6 having the same height as the first stub 5 is further provided at the outer end of the non-light-storing layer 2. Third ridges 7 whose upper surfaces are inclined slightly lower than the second ridges 6 are formed at intervals along the longitudinal direction. In addition, you may increase / decrease the number of protrusions suitably.

The phosphorescent layers 1 and 1 of the phosphorescent regions A and A are formed in a state of being fitted between the first ridges 5 and 5 on both sides thereof, and the upper surfaces of the first ridges 5 and 5 on both sides. Is higher than the upper surface of the phosphorescent layer 1, 1, for example, even if the belt-like covering material 11 is stepped on with footwear during walking, the first protrusion 5, so that the phosphorescent layer 1 is not damaged. 5 can support footwear and protect the phosphorescent layer 1.
The first ridge 5, the second ridge 6, and the third ridge 7 serve to prevent slipping when walking on the strip-shaped covering material 11, for example. In order to further enhance the effect, a large number of ultra-thin ridges (not shown) are formed on the upper surface of each ridge 5, 6 and 7 along the longitudinal direction.

  The width of the ridges 5 is suitably 1 to 5 mm, and the width of the ridges 6 and 7 is suitably 1 to 20 mm. Moreover, it is appropriate that the height of the first ridge 5 and the second ridge 6 is about 0.1 to 2 mm higher than the upper surface of the phosphorescent layer 1 forming the phosphorescent region A. And the 3rd protruding item | line 7 is made into the inclined surface which becomes so low that the upper surface approaches an outer side end, and the height of an inner side end is 0.5-3 mm rather than the height of the 1st and 2nd protruding item | line 5,6. It is appropriate that the height of the outer end is made the same as the thickness of the non-light-storing region B (the thickness of the thin portion where the ridges are not formed). When the width and height of each ridge are set in this way, the above-described phosphorescent layer 1 protecting effect and anti-slip effect can be sufficiently exerted, and the fear of reaching the third ridge 7 is reduced.

Further, as shown in FIGS. 13 and 14, the non-light-storing regions on the center line of the surface of the non-light-storing layer 2 in the non-light-storing region B in the center portion in the width direction of the strip-shaped coating material 11 and the left and right side edges of the strip-shaped coating material 11. In order to improve the bending deformability or the bending deformability, the first small groove 3 described above is formed at the base portion of the second ridge 6 of the non-light-accumulating layers 2 and 2 in B and B. Further, as shown in FIG. 15, the plurality of second small grooves 4 for storing contaminants are formed over the entire length on the surface of the phosphorescent layer 1 in the phosphorescent region A as shown in FIG. Has been.
In addition, although the sticking layer and the release paper are not provided in the back surface of this strip | belt-shaped coating | covering material 11, it cannot be overemphasized that you may provide as needed.

  The material of the luminous layer 1 and the material of the non-luminous layer 2, the elastic modulus of the luminous region A, the elastic modulus of the non-luminous region B, the thickness of the luminous region A, the thickness of the non-luminous region B (convex) The thickness of the thin portion other than the thick portion forming the strips 5, 6, and 7), the width dimension of the strip-shaped covering material 11, the length dimension, the width dimension of the phosphorescent region A, the width dimension of the non-luminous region B, etc. Since it is the same as the above-mentioned belt-shaped covering material 10, description is abbreviate | omitted.

  In addition to exhibiting the same effects as the above-described band-shaped covering material 10, the above-described band-shaped covering material 11 also exhibits the protective effect and anti-slip effect of the phosphorescent layer 1 and improves the design. Therefore, the band-shaped covering material 11 is preferably applied particularly to the bent surface 100 bent substantially at right angles to the nose portion 51a of the staircase 51, and the light-emitting layer in the phosphorescent regions A and A is hardly damaged when the surroundings become dark. 1 and 1 emit light with sufficient brightness, and the belt-like covering material 11 is less likely to slide or crawl, so that safe up and down of the stairs in the dark can be ensured for a long time.

  Next, the effect confirmation test of the strip-shaped coating material according to the present invention will be described.

[Effect confirmation test 1]
9 to FIG. 12 is a flexible strip covering material made of vinyl chloride resin having a total width of 60 mm, a width of the non-light-storing region B in the central portion in the width direction of 10 mm, and a width of the light-storing region A. 10 mm, the width of the non-light-storing region B at both side edge portions is 15 mm, the thickness of the light-storing region A is 1.7 mm, the thickness of the non-light-storing region B is 0.7 mm, and the first, second, and third ridges The width is 1.5 mm, 3 mm, 4 mm, the height of the first protrusion is 2 mm, and the ratio of the luminous area A, the non-luminous area B, and the elastic modulus (non-luminous area B / luminous area A). The strip-shaped coating materials of Examples 1 to 3 and the strip-shaped coating materials of Comparative Examples 1 and 2 as described in Table 1 below were prepared by a coextrusion molding method. And the double-sided adhesive type sticking layer which laminated | stacked the acrylic adhesive layer on both surfaces of the foam layer was provided in the back surface of each strip | belt-shaped coating | covering material.
In addition, the elastic modulus of the luminous area A and the elastic modulus of the non-luminous area B were adjusted by changing the blending amount of the plasticizer blended in the vinyl chloride resin.

  Adhering layer in the longitudinal direction of the SUS steel pipe while curving the belt-like covering material of Examples 1 to 3 and the belt-shaped covering material of Comparative Examples 1 and 2 along the outer circumferential surface of the SUS steel pipe having an outer diameter of 25 mm. The outer peripheral surface (arc surface) of the SUS steel pipe was covered. And the covering state in the initial stage of covering was observed with the naked eye. The results are listed in Table 1 below.

Looking at Table 1, the elastic modulus of the luminous region A is 15 N / mm ² or less, and the ratio of elastic modulus (elastic modulus of the non-luminous region B / elastic modulus of the luminous region A) is 0.65 to 0.95. It can be seen that any of the strip-shaped coating materials of Examples 1 to 3 can be curved and neatly covered without floating along the outer peripheral surface of the SUS steel pipe.
On the other hand, the belt-like coating material of Comparative Example 1 in which the elastic modulus of the phosphorescent region A exceeds 15 N / mm ² is lifted from the outer peripheral surface of the SUS steel pipe at both ends of the phosphorescent region A, and is covered cleanly without gaps along the outer peripheral surface. I understand that I can't.
Further, even when the elastic modulus of the phosphorescent region A is 15 N / mm ² or less, the band-shaped coating material of Comparative Example 2 in which the elastic modulus ratio exceeds 0.95 partially lifts at various places, particularly on both sides of the coating material. It can be seen that the edges rise greatly and cannot be covered neatly without gaps.
In view of the above, the elastic modulus of the phosphorescent region A is 15 N / mm ^{2 in order} to paste the belt-like coating material along the outer peripheral surface (curved surface) of the SUS steel pipe in a width direction and to apply it without any gaps. It was proved that it is necessary to set the ratio of elastic modulus (elastic modulus of non-light-accumulating region B / elastic modulus of luminous region A) to 0.65 to 0.95.

[Effect confirmation test 2]
As shown in Table 2, the band-shaped coating material of Example 2 was attached to the outer peripheral surface of five SUS steel pipes having an outer diameter of 18 to 42 mm via the adhesive layer in the longitudinal direction and the circumferential direction.
Here, sticking in the longitudinal direction on the outer peripheral surface of the SUS steel pipe means sticking in the longitudinal direction of the SUS steel pipe while curving the strip-shaped covering material in the width direction along the outer peripheral surface of the SUS steel pipe. Adhering to the outer circumferential surface of the SUS steel pipe in the circumferential direction is to adhere the belt-shaped covering material in the circumferential direction of the SUS steel pipe while curving the strip-shaped covering material in the length direction along the outer circumferential surface of the SUS steel pipe.
Next, the SUS steel pipe with the strip-like covering material stuck in the longitudinal direction and the circumferential direction was heated at 0 to 50 ° C. (held at 0 ° C. for 1 hour, heated to 50 ° C. over 1 hour, and then at 50 ° C. for 1 hour. Holding and lowering to 0 ° C. over 1 hour), the coating state was observed with the naked eye. The results are shown in Table 2 below.

If this Table 2 is seen, the thing which stuck the strip | belt-shaped coating | covering material to the outer peripheral surface of the SUS steel pipe whose outer diameter is 18 mm in the longitudinal direction, and coat | covered it will be the thing of the phosphorescence area | region A, if 100 cycles of 0-50 degreeC heat cycles are applied. It can be seen that both ends are lifted. And the thing which stuck the strip | belt-shaped coating | covering material to the outer peripheral surface of the SUS steel pipe whose outer diameter is 18 mm in the circumferential direction, and applied the heat cycle of 0-50 degreeC 100 cycles, it is the length direction of a strip | belt-shaped coating | covering material. It can be seen that both ends are lifted.
In addition, the outer diameter of a 25 mm SUS steel pipe with a belt-like covering material attached in the longitudinal direction is covered in the circumferential direction although both ends of the phosphorescent region A are lifted when the above heat cycle is applied. It can be seen that the coated product does not cause a problem of lifting even when the above heat cycle is applied.
And the thing which stuck the strip | belt-shaped coating | covering material to the outer peripheral surface of each SUS steel pipe whose outer diameter is 32 mm, 38 mm, and 42 mm in the longitudinal direction and the circumferential direction, and floats up even if it applies said heat cycle. It turns out that there is no problem.
From the above, the belt-like coating material is stuck and coated along the outer circumferential surface (curved surface) of the SUS steel pipe in the longitudinal direction and the circumferential direction, and it still floats even after 100 cycles of 0-50 ° C heat cycle. It was proved that it is necessary to use a SUS steel pipe having an outer diameter of 30 mm or more in order to prevent the occurrence of defects.
