Definitions

  • the present invention relates to a projecting indicator and a method of manufacturing the same, and more particularly to a projecting indicator, which includes a plurality of projections fixed on an object surface such as a road surface or a wall surface to be used mainly as a sign for guiding the visually impaired, and a method of manufacturing the same.
  • the projecting indicator of the type including the sign for guiding the visually impaired, which is made, for example, by implanting rivets in a concrete block, integrally forming projections with a plate to be laid on a sidewalk, or molding a plate by rubber chips, those of which are placed on a road surface, or embedded in the road surface.
  • the guiding sign made in the above manners may pose a problem of lowering the work efficiency, since it involves works including forming blocks, etc., with preformed projections thereon, transporting those blocks to an actual site and placing or embedding the same.
  • the use of the guiding sign for a prolonged period of time may invite the wearing, or detachment of the rivets for braille and cause the visually impaired to stumble over immediately detaching rivets.
  • the guiding sign poses problems in view of durability and safety.
  • the shape of the projections of the guiding sign is limited to a spherical convex, band-like shape with a convex surface, etc., and therefore the pattern of the guiding sign is limited to a simpler one.
  • the visually impaired can only know the location of a crosswalk, dangerous areas on a train platform, etc., and therefore can not acknowledge a proper direction in order to walk to his or her destination. Consequently, he or she can solely walk to the sites where he or she often come and go, but hardly go to the destination by himself or herself where he or she has never been.
  • the present invention has been made to solve those problems. It is an object of the present invention to provide a projecting indicator such as a sign for guiding the visually impaired, which allows the site installation in easy manner on a road surface, a wall surface, etc., at various sites, and which also enables the visually impaired not only to know the location of a crosswalk, dangerous areas on a train platform, but also to be guided to his or her destination in a relatively easy manner where he or she has never been.
  • a projecting indicator such as a sign for guiding the visually impaired, which allows the site installation in easy manner on a road surface, a wall surface, etc., at various sites, and which also enables the visually impaired not only to know the location of a crosswalk, dangerous areas on a train platform, but also to be guided to his or her destination in a relatively easy manner where he or she has never been.
  • the projecting indicator is characterized by including protrusions 8 separately made from an object surface 7 such as a road surface or a wall surface, and the said projections 8 being bonded to the object surface 7 by solidifying a solidifiable substance 5.
  • the method of manufacturing the projecting indicator is characterized by forming concave portions 12 in a sheet member 1, placing a solidifiable substance 5 into the said concave portions 12, applying a bonding agent 6 on a surface of the said solidifiable substance 5, after the solidifiable substance has been solidified, turning the sheet member 1 upside down, and bonding the solidifiable substance 5 to an object surface 7 such as a road surface or a wall surface via the said bonding agent 6.
  • a method of manufacturing a projecting indicator with projections 8 arranged on an object surface 7 such as a road surface or a wall surface which is characterized by forming concave portions 12 in a sheet member 1, placing a solidifiable substance 5 into the said concave portions 12, applying a bonding agent 6 on a surface of the said solidifiable substance 5, after the solidifiable substance has been solidified, turning the sheet member 1 upside down, bonding the solidifiable substance 5 to the object surface 7 via the said bonding agent, and removing the said sheet member 1.
  • a method of manufacturing a projecting indicator with projections 8 arranged on an object surface 7 such as a road surface or a wall surface, which is characterized by pouring a solidifiable substance 9 onto the object surface 7, forming through holes 10 in the said solidifiable substance, after the solidifiable substance has been solidified, pouring a hot melt resin 11 into the said through holes, and removing the said solidifiable substance 9, after the said hot melt resin 11 has been solidified.
  • the solidifiable substance may be without limitation cement, gypsum, polyester resin, epoxy resin, polyurethane resin, stone dust, rubber, glass or other solidifiable substances.
  • a methacrylate resin which is solidified in 10 to 20 minutes even at -30°C is preferable.
  • the methacrylate resin is preferable to use the methacrylate resin because it has a rubber-like elastic force after solidified.
  • the method of forming the concave portions 12 includes eroding the portions corresponding to the concave portions 12, or solidifying the portions other than the portions corresponding to the concave portions 12 by using an ultraviolet ray curing resin and eroding the portions other than the cured portions to form the concave portions. Both methods are hardly performed at an actual site, and may increase costs. Therefore, it is preferable to form the concave portions by pressing a heated metal bar against the film surface.
  • the synthetic resin film may be without limitation of materials polyethylene terephthalate film, polyethylene film, cellophane, etc., provided that the concave portions can be formed therein.
  • a polyvinyl chloride film which can form therein concave portions having a depth of about 1 cm and a diameter of several mm to about 3 cm in several seconds at 20 to 80°C
  • the polyvinyl chloride film is weak against heat, and hence lose the shape thereof due to the heat, resulting in disposition of the film after a single use.
  • the polyethylene terephthalate film, etc. is advantageous in the fact it is strong to heat, and therefor can be repeatedly used, although it takes a longer period of time to form a concave therein. Accordingly, for manufacturing a large number of the same raised letters, the use of heat resistant films such as the polyethylene terephthalate film are preferable to lower the costs involved.
  • a sheet member 1 made of a polyvinyl chloride film having a thickness of 10 to 30 ⁇ m is brought into a tensioned state by pulling both ends of the sheet member 1, and respective points forming a desired raised letter on the sheet member 1 are determined.

  • the thickness of the sheet member 1, the size of the metal bar 2, the heating temperature and the depth of each concave portion 12 are not limited to the above values, but it is possible to set the values according to the size of a projection manufactured, the type of the sheet member 1 to be used, etc.
  • a projection which can be used as a guiding line when the concave portions 12 each having a depth of 1 cm, a lateral length of 2 cm and a longitudinal length of 10 cm are formed by using a metal bar having a size of 2 cm x 2 cm x 10 cm.
  • metal bar It is possible to use zinc, brass, lead, etc., for the metal bar, and also possible to modify the thickness, and the shape and the temperature of the end of the metal bar according to the quality of the sheet member 1 and the size of a raised letter.
  • the vertical motion of the metal bar can be accomplished through any types including a fixed type, mobile type and arm type.
  • the thrusting operation of the metal bar is made via a direct-acting vale, air cylinder, oil cylinder, water cylinder, etc.
  • a screw 3 is attached to an end of a heating coil 4, and the said screw 3 is screwed into a threaded hole formed in an upper portion of the metal bar 2, thereby supporting the heating coil 4 on the metal bar 2 in a detachable manner.
  • the blend of a methacrylate resin liquid (Acrysirup manufactured by Mitsubishi Rayon Co., Ltd.), aggregate and a curing agent, which blend will be hereinafter referred to "blended resin liquid,” is poured into the concave portions 12.
  • Sands, ceramic, glass powders, or other materials are used for aggregate, and benzoyl peroxide, etc., are used for the curing agent.
  • methacrylate resin liquids of different types which are respectively used for face coating, intermediate coating, and ground coating.
  • the blended resin liquid which is further blended with a resin liquid for face coating for hardening the surface of a raised letter, is poured into a die.
