Description

Prevention of oily graffiti and prevention of adhering to promotional materials using adhesive and night light reflection device

The present invention relates to a device for preventing oily graffiti and preventing the attachment of promotional materials and reflecting light at night using an adhesive, and more particularly, a street lamp, a telephone pole, a power box, a subway wall, or a personal building wall, which are various facilities installed for public purposes. It can prevent oily graffiti and Graffiti graffiti (magic spray and meteor magic) on the back, and prevent illegal promotional materials from being attached without permission, and a promotional material using adhesives and prevention of meteor graffiti that ensures visibility by light reflection at night or in rainy weather. It relates to anti-adhesion and night light reflection devices.

The number of accidents caused by unauthorized crossing of roads nationwide is increasing sharply every year, and this may be due to the lack of orderly awareness of pedestrians and the lack of publicity to prevent traffic accidents. In addition, traffic accidents for children around elementary schools are often caused by the driver's carelessness and traffic congestion caused by illegal parking and stopping in areas where parking and stopping are prohibited along the road. Therefore, traffic accident prevention information can be installed to prevent traffic accidents due to unauthorized crossing, traffic accidents of children around elementary schools, traffic accidents due to unauthorized parking, stopping, etc. You will be able to raise your civic consciousness.

However, even if such information or warning-promoting public interest publicity materials are installed in prominent roadside public facilities, the aesthetics of urban streets are devastated by personal advertising or intentional publicity graffiti, graffiti graffiti, etc. on the surface. Public interest promotional materials are obscured by actions such as sticking paper advertisements for purposes, sticking them with stickers, foam tapes, or scribbling phone numbers with meteor magic, and making it difficult to recognize the unique colors of street public facilities or promotional materials for public interest purposes. There is a problem that the aesthetics of the city is hindered.

In addition, recently, a QR code is printed on public relations materials, and there is a problem in that the QR code is damaged or its function is deteriorated due to scribbles such as promotional meteorology or graffiti graffiti on the QR code portion, or indiscriminately attaching paper advertisements for personal promotion. Also, if the government that manages these actions uses a sharp spatula knife to remove graffiti and promotional materials, the surface of existing facilities may be damaged and rust may occur. It may be damaged or its function may be impaired.

In particular, pillars, walls, apartment entrance doors, traffic light flasher BOX, street light control BOX, power distribution box BOX, etc. are mostly located on the side of the road that is most accessible to the public. Or, Graffiti is scribbled, or paper advertisements for promotion using adhesives are attached. Indiscriminately, graffiti or attachments that are illegally graffitied on the surface of various individuals or public facilities in this way spoil the aesthetics, and if these conditions are left unattended, moral insensitivity, such as the “Warning of Broken Window Theory”. This can lead to unauthorized dumping of garbage or damage to personal and public property, and furthermore, it is a serious social problem as light and heavy crimes may occur.

In addition, when driving at night, other facilities such as road guide posts and speed limit signs are very important to drivers who rely on the upper and lower headlights of the vehicle to drive, so improving the visibility of road facilities is a very important task.

The government or local governments use sharp iron hera to remove publicity and phone number graffiti, Graffiti graffiti, or promotional paper advertisements using adhesive as a means of personal publicity illegally, but public relations materials and roads for public interest purposes If the surface of the facility is damaged, even rust occurs in severe cases, and in order to remove oily graffiti, it has no choice but to overcoat it with paint, greatly damaging the aesthetics of urban streets.

In order to prevent the adhering of promotional materials such as flyers, a support cover made of highly corrosion-resistant metal (Korean Patent Registration No. 10-0566947), while a triangular stone is continuously formed on the front, the triangular stone is molded into an embossed shape, and the rear is insulated when combined with a street lamp. A protective cover for streetlight poles in which a space having a function is formed (Korean Patent No. 10-0952082), stone powder, acrylic resin, polyvinyl acetic acid, and a paint composition containing water (Korean Patent No. 10-1412870) have been reported, It is difficult to protect promotional materials for public interest against activities such as graffiti on public relations and phone numbers or graffiti graffiti with Yoosung Magic, and at the same time, there have been no reports on the function of reflecting light at night.

Accordingly, the inventors of the present invention can easily wipe the graffiti on public facilities such as walls, telephone poles, street lights, traffic lights, or graffiti graffiti on private facilities with a general wet cloth, thereby improving the unique facility maintenance function, and for promoting the surface or public interest of the facility. At the same time, adhesiveness is lowered on the print, and even when advertisements are attached, the adhesive component does not remain, and illegal advertisements can be easily removed without mechanical assistance such as a scraper, and visibility is secured by light reflection at night or in rainy weather. We have developed a device for preventing oily graffiti, preventing adhesion of promotional materials using adhesive, and reflecting light at night.
