More specifically, it is a technology that allows for easy attachment to a road using an adhesive, while also providing an additional fixing structure on the ground surface through adhesive inlet holes on both sides to ensure strong fixing power, and increasing durability through shock absorption means to enable long-term use. Background Technology

[0002] Typically, coated road markers are installed on the lanes of a roadway and reflect light received from vehicles to the drivers of vehicles or pedestrians around the roadway. By equipping these road markers with light-reflecting plates, they provide information regarding lanes and road curves to drivers of vehicles or pedestrians around the roadway with high visibility, thereby enabling drivers of vehicles or pedestrians to move more safely.

[0004] In addition, since they are primarily installed along lanes and protrude above the road surface, if a vehicle crosses the lane, the wheels may run over the road markers, causing vibrations that warn the driver.

[0006] Meanwhile, these conventional road markers are generally fixed to the lanes, either by using fastening means such as bolts or by attaching them to the bottom of the marker using adhesives.

Specific details for implementing the invention

[0028] The present invention provides a retroreflective adhesive road marker and a construction method that allows for easy attachment to a road using an adhesive, while also having an additional fixing structure on the ground surface through adhesive inlet holes on both sides to provide robust fixing power, and can be used for a long period of time by increasing durability through shock absorption means.

[0030] Hereinafter, the preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be described with reference to FIGS. 1 to 15 as follows.

[0032] First, before describing the present invention, the configuration thereof is described with reference to FIGS. 1 to 6. In a retroreflective adhesive road marker installed on a road, the road marker has an inclined surface (11) that slopes from the upper central part toward the outer sides, and one or more adhesive inlet holes (13) are formed on the upper sides such that the diameter of the adhesive gradually decreases from the upper direction toward the lower direction so that the adhesive hardened after being introduced and hardened does not detach in the direction introduced, and a plurality of mutually spaced anti-slip protrusions (15) are formed on the inclined surface (11), and an inlet groove (16) with an open top and side is formed in the other direction where the adhesive inlet hole (13) is formed, and a retroreflector plate (17) that reflects light incident by a headlight, either wholly or partially, is configured on the surface of the inlet groove (16).

[0034] To explain the above road marker (10) in more detail, as shown in FIGS. 1, 3, and 4, a sloped surface (11) is formed that slopes in a curved shape from the upper central part toward both lower sides.

[0035] The above-mentioned slope (11) is a structure designed to minimize impact and ensure smooth movement when a vehicle moves.

[0037] As shown in FIGS. 1, 2, and 4, the adhesive inlet hole (13) is formed on each of the upper sides of the road marker (10), and can be formed so that its diameter gradually decreases as it goes upward and downward. The structure of the adhesive inlet hole (13) is configured such that when a force is generated to pull the adhesive out in the opposite direction of the inlet after the adhesive is inserted, the diameter in the upward direction becomes larger, allowing the adhesive to be inserted more firmly, thereby further improving the adhesive strength.

[0039] At this time, as shown in FIG. 4, the adhesive inlet hole (13) is formed with an upper adhesive inlet hole (13a) and a lower adhesive inlet hole (13b) that extends from the lower part of the upper adhesive inlet hole (13a) and is formed with a smaller diameter, thereby having a structure in which the adhesive is fixed in a double manner. At the same time, the upper adhesive inlet hole (13a) and the lower adhesive inlet hole (13b) are formed completely separately, and an adjacent part (13f) is formed in a horizontal direction in the adjacent part, so that it can ultimately perform the role of holding in a triple structure.

[0041] Meanwhile, as shown in FIG. 5, an extension hole (12) extending outward is formed at the upper part of the upper adhesive inlet hole (13a) and at the central part of the lower adhesive inlet hole (13b), and one or more extension holes (12) formed in the lower adhesive inlet hole (13b) are formed, so that in addition to the triple structure, two additional holding functions can be performed by the extension holes (12), allowing for holding in five parts.

[0043] The above anti-slip protrusions (15) are spaced apart at regular intervals along the inclined surface (11) on the upper side of the road marker (10) and are arranged in two rows, so that when a vehicle runs over the road marker (10), the friction with the tires is increased, thereby preventing the vehicle from slipping.

[0044] At this time, the shape of the anti-slip protrusion (15) can be formed in various shapes such as a circle, an ellipse, a semicircle, or a polygon.

[0046] In the case of the above-mentioned inlet groove (16), as shown in FIGS. 1, 2, and 3, it is formed with the top and side open in the other direction where the adhesive inlet hole (13) is formed, and a retroreflector (17) that reflects light incident by a headlight, either wholly or partially, is attached to the surface of the above-mentioned inlet groove (16).

[0047] That is, the above-mentioned inlet groove (16) serves the role of allowing the worker's hand to be easily positioned when gripping the road marker (10), and simultaneously serves the role of providing a space to which the above-mentioned retroreflective plate (17) can be attached.

[0049] Meanwhile, in the above-mentioned inlet groove (16), as shown in FIGS. 2 and 3, a first attachment surface (19a) that slopes outward as it goes from the top to the bottom, and a second attachment surface (19b) that extends from the lower end of the first attachment surface (19a) and continues in a horizontal direction are formed, and a retroreflective plate (17) is attached to the first attachment surface (19a) or the second attachment surface (19b) alone or separately.

[0050] Here, the inclined structure of the first attachment surface (19a) is an inclined structure that allows light to be reflected into the driver's field of vision when light is irradiated from the vehicle, and the second attachment surface (19b) is also designed so that light can be irradiated in a vertical direction, thereby ensuring visibility when the driver is driving on the road and providing safety.

[0052] In addition, as shown in FIG. 7 (side cross-sectional view), slide holes (13c) are formed vertically on both sides of the inlet groove (16), and slide members (14) are configured on both outer sides to slide into the slide holes (13c), and a retroreflective plate (17) is attached to the outer side of the slide members (14).

[0053] The structure of the slide member (14) allows the entire slide member (14) to be replaced rather than removed when the retroreflector (17) is peeled or damaged due to long-term use, thereby providing convenience when maintenance is required. In addition, since the safety of the vehicle driver may not be guaranteed if the retroreflector (17) fails to perform its function properly due to poor repair, the safety of the vehicle driver can be ensured by replacing it with a completely new one.

[0055] In addition, as shown in FIG. 4, the road marker (10) has a number of protrusions and indentations formed on its lower surface to allow adhesive to be drawn in, thereby increasing the overall durability of the road marker.

[0057] Meanwhile, as illustrated in FIG. 8, the lower part of the road marker further includes a fastening plate (21) that is inserted into the road and fastened in a protruding lower portion, a lower plate (23) that is fastened to the upper portion of the fastening plate (21), a plurality of elastic members (25) configured to mitigate impact on the upper edge of the lower plate (23), and an upper plate (27) of the same shape as the lower plate (23) configured on the upper portion of the elastic members (25), and an impact absorption means (20).

[0058] As shown in FIG. 9, the above fastening plate (21) has a structure that is rotatably coupled to a fixing means (30) to be described below, which protrudes downward from the lower central part, and has screw threads formed on its outer circumference. In addition, an insertion groove (21a) is formed on the side of the above fastening plate (21), so that the upper part of the side fastening member (33) of the fixing means (30) to be described below can be inserted into the insertion groove (21a) and fixed.

[0060] The lower plate (23) is configured on the upper part of the fastening plate (21) and can be joined to each other through bolts or other connecting means. The elastic member (25) is configured to be arranged at regular intervals or very fine intervals along the upper edge of the lower plate (23), so that when the upper part of the road marker (10) to be attached is pressed by a vehicle, it moves downward, thereby improving the ride comfort of the vehicle driver and allowing the road marker (10) to absorb the impact with the vehicle, thus enabling long-term use.

[0061] The upper plate (27) is formed with the same structure and shape as the lower plate (23) and is configured to cover the upper part of the elastic member (25), and the upper part is mutually attached to the road marker (10) by an adhesive.

[0062] At this time, it is preferable that the upper part of the top plate (27) be formed as a flat surface so that it can come into complete contact with the lower part of the road marker (10).

[0064] Additionally, as illustrated in FIG. 8, a fixing means (30) is configured such that the lower part of the shock absorbing means (20) is positioned in the groove (h) of the road, and a fastening hole (31a) is formed in the upper central part to be coupled with the lower part of the fastening plate (21), and fitting holes (31b) are formed vertically on both outer sides, and a coupling hole (31c) is formed at a certain interval from the fitting holes (31b); and a side fastening member (33) is configured to be fastened to the body part (31) and the fastening plate (21) by means of a fastening means (b), and the central part and the lower part are inserted into the fitting holes (31b) and arranged to be in close contact with the body part (31), and the upper part is bent inward to be fitted or hooked onto one side of the fastening plate (21) to fix the fastening plate (21) and the body part (31).

[0066] The above fixing means (30) ultimately serves as a base plate that prevents the road marker (10) from detaching from the road after it is attached to the shock absorbing means (20) with an adhesive, and also ensures stable operation of the shock absorbing means (20).

[0067] As shown in FIG. 10, the above body part (31) has a fastening hole (31a) formed in the upper central part so that the lower part of the fastening plate (21) can be fastened, and it is preferable that screw threads be formed in the fastening hole (31a).

[0068] Additionally, fitting holes (31b) are formed in a vertical direction on both outer sides of the body part (31), so that the side fastening member (33) can be positioned so that all three sides except one side come into contact with each other, thereby maintaining a vertical state without twisting, and the coupling holes (31c) spaced apart at a certain distance from the fitting holes (31b) are configured to allow the side fitting member (33) to be coupled through the fastening member (b).

[0070] In the case of the above-mentioned side fastening member (33), it is fastened to the coupling hole (31c) of the body part (31) and the fastening member (b), and three sides come into contact with the insertion hole (31b), and one side of the upper side is bent inward so as to be inserted into the insertion groove (21a) of the fastening plate (21) so as to fix the fastening plate (21) and the body part (31).

[0071] At this time, when connecting to the body part (31) through the fastening member (b), a plurality of holes (not shown in the drawing) are formed for connecting the fastening member (b).

[0072] The above-mentioned side fastening member (33) can have a more robust fixing force by fixing the outer surface once more while the body part (31) and the fastening part (21) are mutually fastened.

[0074] The method of installing the road markers as described above on the road is explained as follows with reference to FIGS. 11 to 15.

[0076] As illustrated in Fig. 11, the method for constructing road markers consists of a first step (S100), a second step (S200), a third step (S300), a fourth step (S400), and a fifth step (S500).

[0078] The first step (S100) above is a step of forming a groove (h) in the road using road drilling equipment, as illustrated in FIG. 12. At this time, it is preferable that the diameter of the groove (h) be formed slightly larger than the circumference of the road marker. This is so that convenience can be provided when inserting the road marker into the groove (h).

[0080] The second step (S200) above is a step of attaching a shock absorbing means (20) to the upper part of the body portion (31) of the fixing means (30), as shown in FIG. 13, and the fastening plate (21) of the shock absorbing means (20) and the body portion (31) can be rotated together to have a strong fixing force.

[0082] The third step, as illustrated in FIG. 13, involves attaching a side fastening member (33) to the side of the body part (31), such that the inner side of the side fastening member (33) is in complete contact with the outer side of the body part (31), and the upper side is fixed to one side of the outside of the shock absorbing means (20) so that the shock absorbing means (20) does not twist.

[0084] The fourth step, as illustrated in FIG. 14, is a step of inserting the fixing means (30) to which the shock absorbing means (20) is fastened into the groove (h), and then filling it so that it covers only a portion of the lower part of the shock absorbing means (20). At this time, the purpose of filling is to minimize the gap as the groove (h) is formed larger than the circumference of the road marker (10), and the range of the portion that covers only a portion of the lower part of the shock absorbing means (20) refers to the range up to the fastening plate (21) and the bottom plate (23).

[0085] In addition, the reason for not filling up to the upper direction of the lower plate (23) is that if foreign substances such as soil or other filling materials are introduced into the elastic member (25), it may act as an obstacle to the elastic member (25) having elastic restoring force.

[0086] Due to this problem, instead of filling with soil or other materials, a filling member (m) is inserted to seal the space between the groove (h) of the road and the outer side of the shock absorption means (20) to prevent foreign substances from entering.

[0089] The above fifth step (S500) is a step of applying adhesive to the upper side of the shock absorption means (20), positioning the retroreflector (17) in the direction in which the vehicle is moving, and then attaching the lower part of the road marker (10) to the shock absorption means (20) so that the adhesive is positioned in the adhesive inlet hole (13).

[0091] According to the retroreflective adhesive road marker and construction method of the present invention, while maintaining the original purpose of the adhesive road marker, it is possible to easily attach it to the road using an adhesive, and by providing additional fixing means in addition to the bottom surface through adhesive inlet holes on both sides, it is possible to have a strong fixing force, and furthermore, through a shock-absorbing structure, durability is improved so that it can be used for a long period of time, making it a useful invention.
