Specific details for implementing the invention

[0011] Hereinafter, an information sign with improved adhesive strength and condensation prevention function according to embodiments of the present invention will be described with reference to the drawings.

[0012] FIG. 1 is a front view of a guide sign with improved adhesive strength and condensation prevention function according to the first embodiment of the present invention, FIG. 2 is a rear view of a guide sign with improved adhesive strength and condensation prevention function according to the first embodiment of the present invention, FIG. 3 is a cross-sectional view showing the configuration of a sign member constituting a guide sign with improved adhesive strength and condensation prevention function according to the first embodiment of the present invention, and FIG. 4 is a drawing showing a sign fixing member constituting a guide sign with improved adhesive strength and condensation prevention function according to the first embodiment of the present invention.

[0013] Referring to FIGS. 1 to 4 together, the guide sign (100) with improved adhesive strength and condensation prevention function according to the present embodiment is installed around a road to provide driving information for driving a vehicle to a vehicle driver and includes a support member (110), a horizontal bar (115), a sign member (120), a sign frame member (125), and a sign fixing member (130).

[0014] The above support member (110) is formed in the shape of a rod of a predetermined length, and the lower end is inserted into the installation surface and erected vertically on the installation surface.

[0015] The above support member (110) is made of a metal material such as iron or aluminum.

[0016] The horizontal bar (115) is formed vertically with respect to the support member (110) and a pair is arranged at different heights, thereby supporting the sign member (120) from the rear of the sign member (120) and reinforcing the rigidity of the sign member (120).

[0017] The above sign member (120) is formed in the shape of a flat plate with a predetermined area, such as an aluminum plate, and the driving information is written thereon.

[0018] Here, the driving information refers to the vehicle's speed limit, direction of travel, information on the current location, child protection zone information, etc.

[0019] The above sign member (120) includes a sign body (121), a reflective sheet (122), and a condensation prevention film (123).

[0020] The above sign body (121) is made of a metal material such as aluminum, and is formed in the shape of a flat plate with a predetermined area, having a shape such as a circle, triangle, or square depending on the type of driving information.

[0021] The above reflective sheet (122) covers the front surface of the above sign body (121) and retroreflects light entering from the outside.

[0022] The front surface of the above sign body (121) is the side that the vehicle driver looks at while driving, and is the side opposite to the side to which the horizontal bar (115) is attached among the above sign members (120).

[0023] The aforementioned retroreflection refers to a reflection that returns externally introduced light back in the direction of incidence to improve visibility.

[0024] The reflective sheet (122) is attached to the sign body (121) after the surface roughness of the front surface of the sign body (121) has been polished to 0.5 to 5 μm.

[0025] Then, the adhesive component of the reflective sheet (122) is introduced into the polished portion of the sign body (121), thereby increasing the adhesive area between the reflective sheet (122) and the sign body (121) relatively, so that the adhesive strength between the reflective sheet (122) and the sign body (121) is improved, and accordingly, the phenomenon of the reflective sheet (122) lifting off the sign body (121) can be prevented even in the summer when the temperature is high or in weather with large daily temperature fluctuations.

[0026] The above condensation prevention film (123) covers the front surface of the above reflective sheet (122) to prevent condensation from forming on the above reflective sheet (122).

[0027] When condensation occurs on the sign member (120), the light from the vehicle reflected on the reflective sheet (122) causes diffuse reflection, which prevents accurate driving information from being conveyed to the driver of the vehicle. However, by forming the condensation prevention film (123), diffuse reflection on the reflective sheet (122) can be prevented.

[0028] The above condensation prevention film (123) is made of polyethylene terephthalate (PET) material.

[0051] In this embodiment, the second sign fixing part (137) is formed to have the same configuration and shape as the first sign fixing part (131), and the first sign fixing part (131) and the second sign fixing part (137) are arranged symmetrically to each other in the vertical direction with respect to the horizontal bar (115).

[0052] The second fixed body (138) is formed with a predetermined curvature and is formed to face the first fixed body (132), so as to surround the other parts of the outer surface of the horizontal bar (115), excluding the part surrounded by the first fixed body (132).

[0053] In this embodiment, the second fixed body (138) is formed in a semicircular shape.

[0054] The second fixed extension (139) is extended outwardly by a predetermined length from the end of the second fixed body (138) and is formed parallel to the first fixed extension (133).

[0055] The second end bending portion (140) is bent upward at the end of the second fixed extension (139).

[0056] That is, the second end bending part (140) protrudes by bending toward the first sign fixing part (131) from the end of the second fixing extension (139) when the horizontal bar (115) is surrounded by the first sign fixing part (131) and the second sign fixing part (137).

[0057] The second support member (141) is coupled to the outside of the second fixed body (138) and is formed with a predetermined length in the direction opposite to the direction in which the second fixed extension member (139) extends.

[0058] The second support-side through hole (142) is formed by penetrating the second support member (141) so that a part of the vertical frame member (127) can be inserted for connecting the vertical frame member (127) and the second signboard fixing member (137).

[0059] The second support-side through hole (142) is formed to penetrate in a shape corresponding to a part of the vertical frame part (127) with a portion of the front open, similar to the first support-side through hole (136) shown in FIG. 4, and a portion of the vertical frame part (127) (in the case of an I-shaped steel, a portion extended outward from the upper end) is inserted into the second support-side through hole (142), thereby connecting the second signboard fixing part (137) to the vertical frame part (127).

[0060] The above fixing means (145) is configured to connect the first sign fixing part (131) and the second sign fixing part (137) while the first sign fixing part (131) and the second sign fixing part (137) surround the horizontal bar (115) so that the sign member (120) is fixed to the horizontal bar (115), and includes a fixing bolt (146) that penetrates the first fixing extension (133) and the second fixing extension (139), and a fixing nut (147) connected to the portion of the fixing bolt (146) that penetrates the first fixing extension (133) and the second fixing extension (139).

[0092] The above-mentioned pressure body (266) is rotatably connected to the inner side push part (261) by inserting the rotation shaft (264).

[0093] The lower protrusion (267) protrudes from the lower part of the pressurized body (266) toward the outward protrusion (244) and comes into contact with the outward protrusion (244).

[0094] The above-mentioned pressure protrusion (268) protrudes from the upper part of the pressure body (266) in the same direction as the lower protrusion (267) protrudes, and presses the fixing bolt (246) when the fixing bolt pressure part (265) rotates.

[0095] When the fixing nut is fastened to the fixing bolt (246) while the fixing bolt (246) is penetrating the first fixing extension (233) and the second fixing extension (239), the first fixing extension (233) and the second fixing extension (239) are elastically deformed in a direction that brings them closer to each other, causing the first end bending part (234) to spread outward. Due to the spreading of the first end bending part (234), the inner surface push part (261) is inserted into the elastic space (243), thereby pulling the fixing bolt pressing part (265) toward the first fixing extension (233), and at the same time, the outward protrusion (244) pushes the lower protrusion (267). Accordingly, the fixing bolt pressing part (265) rotates around the rotation axis (264), and the head of the fixing bolt (246) By pressing the upper portion that forms the part with the pressure protrusion (268), the unintended loosening of the fixing means from the first sign fixing part and the second sign fixing part can be prevented.

[0096] Hereinafter, a guide sign with improved adhesive strength and condensation prevention function according to the third embodiment of the present invention will be described with reference to the drawings. In carrying out this description, any descriptions that overlap with the contents already described in the first embodiment of the present invention described above will be replaced and omitted here.

[0097] FIG. 7 is an enlarged view showing a part of the configuration of a sign fixing member constituting a guide sign with improved adhesive strength and condensation prevention function according to the third embodiment of the present invention.

[0098] Referring together with FIG. 7, in this embodiment, a first sign fixing part constituting a sign fixing member includes a first inward protrusion (334a), and a second sign fixing part includes a second inward protrusion (340a).

[0099] The first inward protrusion (334a) is bent from the end of the first end bending part (334) toward the inside of the elastic space (343), that is, toward the first fixed body, and protrudes for a predetermined length.

[0100] The second inward protrusion (340a) is bent from the end of the second end bending part (340) toward the inside of the elastic space (339), that is, toward the second fixed body, and protrudes for a predetermined length.

[0101] The first inward protrusion (334a) and the second inward protrusion are positioned to face each other when the first sign fixing part and the second sign fixing part surround the horizontal bar.

[0102] In the state formed as described above, when the first sign fixing part and the second sign fixing part are fastened by the fixing bolt (346) and the fixing nut (347) and the first fixing extension (333) and the second fixing extension (339) are elastically deformed in a direction that brings them closer to each other, the first end bending part (334) and the second end bending part (340) spread outward, and at the same time, the bottom surface of the first inward protrusion (334a) and the top surface of the second inward protrusion (340a) come into contact with each other, thereby forming a friction surface of a predetermined area.

[0103] Then, the connection state between the first sign fixing part and the second sign fixing part can be maintained by the friction surface formed between the bottom surface of the first inward protrusion (334a) and the top surface of the second inward protrusion (340a), and accordingly, the fixation of the sign fixing member to the horizontal bar can be stably maintained.

[0104] Although the present invention has been illustrated and described above with respect to specific embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims. However, it should be clearly stated that all such modifications and variations are included within the scope of the present invention. Industrial applicability
