Description

Sealed Double-Side Road Sign Supported by Crossbar The present invention relates to a road sign, and more specifically, to a double-sided road sign installed on both sides of a crossbar fixed horizontally from a support post. Various types of road signs are installed along roads. Road signs include regulatory signs (stop, no parking/stopping, speed limit, no entry, etc.), directional signs (right turn, straight ahead, bicycle lane, etc.), informational signs (milestones, highway exits, rest area information, distance indicators, etc.), auxiliary signs (travel time restrictions, road name information, direction indicators, etc.), and warning signs (sharp curves, slippery roads, child protection zones, etc.). Among these, milestone signs, speed limit signs, distance markers, and time-of-traffic restriction signs are frequently installed on roads within cities. These road signs are relatively wide and tall, and to ensure visibility for drivers, they are installed on crossbars that are horizontally fixed from the top of the support posts toward the road. Although crossbar-supported road signs can be installed very securely using brackets, bands, bolts, and nuts to prevent them from falling onto the road, they are typically installed as single-sided signs that are visible only in the direction of travel. Consequently, the crossbars, mounting brackets, bands, bolts, and nuts are exposed on the back of the signs, detracting from the urban landscape. Furthermore, while milestone signs, speed limit signs, distance markers, and time-of-traffic restriction signs need to be visible from the opposite direction of travel or on sidewalks on urban roads, single-sided road signs present the disadvantage of being invisible from these directions. The invention disclosed in Published Utility Model Publication No. 20-1998-0009420 improves the panel of a road guidance sign into a double-layered structure, so that road guidance is displayed on one side and decorative elements, promotional materials, etc., are expressed on the other side through pictures or text, while also ensuring that supporting posts, fastening members, etc., are not exposed to the outside. The invention in Published Utility Model Publication No. 20-1998-0009420 consists of a first panel on which a road guidance display is expressed on the front; a second panel on which decorative elements, promotional materials, etc., are expressed through pictures or text; a supporting post that supports the first and second panels; and a fastening member that fixes the first and second panels to the supporting post. The drawings of the invention in Published Utility Model Publication No. 20-1998-0009420 show that bolts and band-type fasteners can be used as fastening members. However, according to the invention of Public Utility Model Publication No. 20-1998-0009420, it is very difficult or impossible to fasten the second panel to the crossbar with bolts and fasteners after fastening the first panel to the crossbar with bolts and fasteners. This is because when fastening the second panel to the crossbar with bolts and fasteners while the first panel is installed, the space between the first and second panels is narrow, making it difficult for a worker to enter or reach in to fasten the bolts and band-type fasteners. This is also the reason why conventional crossbar-supported road signs have been manufactured only as single-sided structures. In addition, according to the invention of Public Utility Model Publication No. 20-1998-0009420, when a vehicle traveling in both directions on the road is covered by the first panel and the second panel, the support posts and fastening members are exposed in the side space between the first panel and the second panel on both sides of the road, thus still damaging the urban aesthetic. The invention disclosed in Registered Patent Publication No. 10-0202288 addresses the problem that crossbar-supported road signs are unsightly and detract from the aesthetics when viewed from the rear. To resolve this, the invention features a road sign configured to cover the rear of the front sign by installing a reinforcing tube and a stainless steel frame inside a high-flex panel containing a realistic image on the rear side, and attaching flat iron hooks to the reinforcing tubes to hang and secure them to a connecting pipe (crossbar). The high-flex panel displays images or photographs of famous tourist attractions of the local government. Additionally, finishing plates are installed on the upper and lower sides to prevent rainwater or snow from entering the interior, thereby preventing rust. However, since the invention in Registered Patent Publication No. 10-0202288 is structured so that flat iron hooks are installed on the reinforcing tubes of the high-flex panel and simply rested on the connecting pipe (crossbar), while installation is easy, the high-flex panel may fall due to strong winds, potentially causing safety accidents.
