Description

  The present invention relates to stair components such as handrails and footboards that constitute stairs installed in buildings such as houses, hospitals, and schools.

In staircases installed in buildings such as houses, hospitals, schools, etc., there are many cases where the lighting is not so bright, so it is difficult to check the position of the treadboard at night. It is necessary to be careful, and if not careful enough, there is a risk of falling off the tread board.
Also, in the event of a power failure, it is not possible to confirm the presence of the stairs, not just the position of the treads, making it difficult to ascend or descend the stairs or fall off the treads and cause serious injury. It was.

  Therefore, conventionally, the fluorescent paint is applied to all or part of the handrails and treads of the stairs, and if there is a nighttime or a power outage, all or part of the handrails, treads, etc. will emit light and the presence of the stairs Has been proposed to make it easy to confirm the position of the tread board so that it can be ascended and descended without removing the tread board (see Patent Documents 1 and 2).

JP2003-208808

  However, in the conventional staircase, since the fluorescent paint is applied only to the surface portion of the handrail, the tread board, etc., the fluorescent paint is easily applied due to the wear of the surface portion due to use, or due to the abrasion or breakage of the surface portion. Peeled off, and the light emitting action disappeared relatively early.

  In addition, since the fluorescent paint is uniformly applied to the surface portions of the handrail, the tread board, etc., the light emitting action is relatively intense, which causes anxiety to the user. Furthermore, since it emits light uniformly, it caused a cold inorganic texture.

  In addition, the fluorescent paint has a problem in weather resistance, such as being weak against ultraviolet rays, and has a problem that the light emitting action gradually disappears if there are stairs in the place where the sunlight hits.

  The present invention has been made in view of such conventional problems, and the light emitting action disappears early due to wear or the like of the surface portion due to use, or due to abrasion or damage of the surface portion. The light-emitting action is relatively mild, the user can feel uneasy, the design can be retained, the warm organic texture is raised, and the weather resistance is not a problem. An object of the present invention is to provide a stair component member such as a handrail or a tread that does not easily lose its light-emitting action even if a stair is present in a place where the light beam hits.

  In order to achieve the above object, the present invention is characterized in that a molded product formed by mixing scaly mica particles coated with a phosphorescent pigment with a synthetic resin is used as all or part of a stair component.

Hereinafter, preferred embodiments of the staircase constituting member of the present invention will be specifically described with reference to the drawings.
The staircase constituting member of the present invention uses a molded product formed by mixing scaly mica particles coated with a phosphorescent pigment with a synthetic resin, as a whole or a part thereof.

Mica is a natural mineral that is easy to peel off in a thin layer, is rich in elasticity, and has high electrical insulation and heat resistance. ) Etc.
In the present invention, mica is crushed into scaly particles, but as mica, muscovite is preferably used, and the particle diameter is 0.5 to 5 mm, particularly 0.5. It is preferable to use one having a thickness of ˜3 mm.

Phosphorescent pigments are pigments that absorb and store light energy from sunlight during daytime and emit light by releasing the stored light energy at night. Strontium aluminate, europume dysprossum Etc. as components.
In addition, a colorant such as titanium oxide or carbon black may be further added to the phosphorescent pigment.

To coat scaly mica particles with phosphorescent pigment, first prepare a blended product of phosphorescent pigment, solvent such as toluene and ethyl acetate, binder such as acrylic resin, and crosslinking agent such as epoxy resin, Then, the scaly mica particles and the blended product are mixed and dried.
The step of coating the scaly mica particles with the phosphorescent pigment is preferably repeated a plurality of times in order to increase the emission luminance.
Furthermore, a blended product is prepared by mixing a solvent such as toluene and ethyl acetate, a binder such as an acrylic resin, and a crosslinking agent such as an epoxy resin, and then mixing the dried scaly mica particles with the blended product. And then dry.

Then, scale-like mica particles coated with a phosphorescent pigment are mixed with a synthetic resin such as ABS resin, polypropylene, polyester, polyurethane, etc., and a molded product having an appropriate shape and structure is formed by an appropriate molding method such as compression molding, extrusion molding, and hollow molding. Mold.
Here, the phosphorescent pigment contained in the synthetic resin is preferably 1 to 10% by weight, and particularly preferably 3 to 8% by weight.

  Here, since mica easily peels off into a thin layer, the pulverized mica particles are scale-like, and the mica has high heat resistance. Therefore, even if the mica particles are mixed with the synthetic resin and molded, The scaly mica particles are mixed in the form of dots in the molded product.

Therefore, when the molded product is used as all or part of the staircase constituent member, when the nighttime or a power failure occurs, the scaly mica particles mixed in a dotted manner in the molded product emit light, and the molded product is Since it appears to emit light in spots, and the light emission action is relatively mild, it does not cause the user to feel uneasy.
In addition, by appropriately regulating the state of mixture of scale-like mica particles in the molded product, various patterns such as marble tone, stone tone, and starry sky pattern can be formed, and design properties can be retained. It is possible to provoke a warm organic texture to the user.

  In addition, when the molded product is used as all or part of the staircase constituent member, scaly mica particles are also mixed inside the molded product. Even if the part is scratched or damaged, the light emitting action does not disappear early.

  In addition, when the molded product is used as all or part of the staircase components, the phosphorescent pigment has good weather resistance and light resistance, so it is easy even if the staircase is in a place where it is exposed to sunlight. The light emitting action is not lost.

  In addition, you may use the molded article formed by mixing the scaly mica particle which coated the phosphorescent pigment with the synthetic resin, and mixing wood chip powder as a structural member. Wood dust is contained in the molded product in an amount of 10 to 50% by weight, preferably 30 to 40% by weight.

  If wood dust is mixed in the molded product, a wooden texture can be imparted to the molded product, which is close to a wooden furniture tone, and a warmer organic texture can be caused to the user.

The case where the present invention is applied to the handrail 12 of the stairs 11 will be described.
As shown in FIG. 1, in the handrail 12, molding is performed by mixing scaly mica particles coated with a phosphorescent pigment into a synthetic resin over the entire length direction or part of the length direction. Goods are applied.

  Since the handrail 12 is guided and grasped by a hand when going up and down the stairs 11, if the above molded product is applied thereto, the handrail 12 that emits light at night or when a power failure occurs. Can be moved up and down the stairs, and the stairs 11 can be reliably moved up and down without removing the tread.

  Further, the handrail 12 is susceptible to surface wear, surface abrasion, damage, etc. due to use, but since the flaky mica particles are also mixed inside the molded product, the light emitting action disappears early. There is no end.

A case where the present invention is applied to the tread 13 of the stairs 11 will be described.
As shown in FIG. 1, in the tread 13, the phosphorescent pigment over the whole length direction or a part of the length direction, and over the whole width direction or a part of the width direction. A molded product obtained by mixing the scaly mica particles coated with bismuth with a synthetic resin is applied.

  Since the step board 13 travels by landing on the foot when going up and down the stairs 11, if the molded product as described above is applied thereto, the step board 13 that emits light at night or when a power failure occurs. The stairs 11 can be climbed up and down, and the stairs 11 can be reliably climbed up and down without removing the tread.

  Further, the tread 13 is susceptible to surface wear, surface abrasion, damage, etc. due to use, but since the flaky mica particles are also mixed inside the molded product, the light emitting action disappears early. There is no end.

  The present invention can be applied not only to the handrail 12 and the step board 13 but also to a stair component, such as a row girder constituting a stair, as appropriate.

It is an external appearance perspective view of the stairs to which the present invention is applied.
