Technical Field

[0005] , , , , , , , ,

[0001] The present invention relates to a pedestal for installing a road marking body in an inclined manner with respect to an installation surface, and an installation structure and method of the road marking body.

Background Art

[0002] A road marking body provided with a marking portion on a columnar portion is used as a sight guidance mark or a lane separation mark. Since such a road marking body is often provided so that the column portion stands perpendicular to the installation surface, when installed on an inclined surface such as a slope, the columnar portion is not in the vertical direction but is arranged in an inclined manner with respect to the vertical direction.

[0003] When installing such a road marking body on an inclined installation surface, a configuration for erecting the columnar portion in a direction closer to the vertical has been studied, and various inventions have been published. For example, in Patent Document 1, there is disclosed an angle adjusting member that is disposed between a lane separation mark and an installation surface on which the lane separation mark is installed, and adjusts the installation angle of the lane separation mark with respect to the installation surface. The angle adjusting member includes a first surface facing the bottom surface of the lane separation mark, a second surface facing the installation surface and inclined with respect to the first surface, and a through hole penetrating from the first surface to the second surface.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The angle adjustment member shown in Patent Document 1 allows for adjustment of the installation angle of a lane divider by forming a first surface corresponding to the upper surface and a second surface corresponding to the lower surface so as to be inclined and placing it between the installation surface and the lane divider. However, when the inclination angle is small, it is difficult to accurately determine the direction of the inclination, which presents a problem as confirmation during installation work is cumbersome.

[0006] The present invention provides a base for installing a road marking body at an inclination relative to the installation surface, which allows for easy determination of the direction of the inclination. [Means for solving the problem]

[0007] To achieve the above objective, the present invention has the following configuration. In other words, the base according to the present invention is a base that is placed between a road marking body, which comprises a base portion and a column portion extending upward from the base portion, and the installation surface, wherein the top surface of the base is inclined relative to the bottom surface, and a guide portion is formed therein for determining the direction of the inclination of the top surface relative to the bottom surface.

[0008] Furthermore, the installation structure for road markings according to the present invention is characterized in that the base, in which the inclination of the upper surface relative to the lower surface grasped by the marking portion is directed in the opposite direction to the inclination of the installation surface, is placed on the installation surface, and the road marking is installed on the base.

[0009] According to the installation structure of the base and road marking body according to the present invention, the upper surface of the base is arranged inclined relative to the lower surface, so that the base can be placed between the road marking body and the installation surface, and the road marking body can be installed inclined relative to the installation surface. Furthermore, since a guide mark is formed on the base to determine the direction of the inclination of the upper surface relative to the lower surface, the direction of the inclination of the base can be easily determined and it can be installed on the mounting surface.

[0010] Furthermore, the method for installing a road marking according to the present invention is characterized by including the steps of: positioning the base so that the direction of the inclination of the upper surface relative to the lower surface grasped by the marking portion is in the opposite direction to the inclination of the installation surface; installing the base on the installation surface; and installing the road marking on the base.

[0011] The method for installing a road marking according to the present invention includes the step of positioning the base so that the direction of the inclination of the upper surface relative to the lower surface grasped by the marking portion is in the opposite direction to the inclination of the installation surface. Therefore, the orientation of the base relative to the installation surface can be easily adjusted, and the orientation of the base relative to the installation surface can be accurately adjusted. Furthermore, since the process includes the steps of installing the base on the installation surface and installing the road marking on the base, the road marking can be installed at an inclination with respect to the installation surface.

[0012] Furthermore, the indicator portion may be formed in a position that can be seen from above the base.

[0013] Furthermore, the base may be provided with a male screw portion that protrudes upward from its upper surface.

[0014] Furthermore, the male screw portion may be formed only once, near the center of the base in a plan view. [Effects of the Invention]

[0015] According to the base, road marking structure, and installation method of the present invention, the direction of the base's inclination can be easily determined and the base can be installed on the installation surface. [Brief explanation of the drawing]

[0017] Embodiments of the present invention will be described based on the drawings. Figure 1 is a front view showing one embodiment of the base 1 according to the present invention, Figure 2 is a plan view of Figure 1, and Figure 3 is a cross-sectional view AA of Figure 2. The base 1 comprises a plate-shaped base 11 and a male screw portion 12 that protrudes upward from the upper surface of the base 11. The base 1 has a male screw base portion 3 and an inclined base portion 2 which is formed separately and positioned above the male screw base portion 3, and these two components constitute the base portion 11 and the male screw portion 12. In the following explanation, the vertical direction in Figure 1 will be referred to as the vertical direction, the horizontal direction perpendicular to the vertical direction will be referred to as the horizontal direction, and the direction perpendicular to both the vertical and horizontal directions will be referred to as the width direction.

[0018] Figure 4 is a front view showing the inclined base portion 2 and the male screw base portion 3 separated from each other in Figure 1. The male screw head portion 3 has a disc-shaped base plate 31, and the base plate 31 constitutes a part of the base portion 11. A bolt 35 is fixed to the center of the substrate 31, and the male thread 35a of this bolt 35 forms the male thread portion 12. Specifically, as shown in Figure 3, the male thread 35a of the bolt 35 is inserted through the substrate 31 from below and protrudes upward. Although the substrate 31 is formed from a stainless steel plate, it is not limited to this, and any metal material can be suitably used. Specifically, ferrous metal materials including special steels such as stainless steel and ordinary steel, and non-ferrous metal materials such as aluminum alloys can be used. Furthermore, corrosion resistance and other properties may be improved by applying chemical conversion treatments such as chromate treatment, or surface treatments such as plating and painting.

[0019] The bolt 35 is a so-called weld bolt having a disc-shaped head, and the head is welded to the metal base plate 31 for fixation. A circular recessed storage section 32 is formed on the lower surface of the base plate 31 by press forming, and the head of the bolt 35 is housed inside this storage section 32. The bolt 35 is fixed so that its male thread 35a is positioned perpendicular to the flat base plate 31.

[0020] The inclined base portion 2 is a plate-like body made of ethylene propylene diene rubber (EPDM) and constitutes a part of the base portion 11. As shown in Figure 2, the inclined base portion 2 is formed in a roughly oval shape in plan view, and the straight edges 24 formed at each end on both the upper and lower sides in the figure are arranged parallel to each other in the circular outer periphery. Each of these linear edges 24 is formed to follow the horizontal direction, which is the left-right direction in the figure, as shown in Figure 2, and functions as a directional section 23, which will be described later. Furthermore, a circular through-hole 25 is formed in the center of the inclined base section 2, extending vertically through it. Although the inclined base section 2 shown in Figures 1-4 is made of EPDM, it is not limited to this material and may be made of other materials. For example, it can be made by selecting or combining synthetic rubber, natural rubber, polyurethane, polyvinyl chloride, or other elastomers. Alternatively, the inclined base section 2 may be made using other synthetic resins or hard materials such as metal.

[0021] The inclined base section 2 has a flat upper surface 21 and a lower surface 22, and as shown in Figure 4, the upper surface 21 and the lower surface 22 are arranged in an inclined manner rather than parallel in a front view. Specifically, in Figures 1 to 4, the thickness between the upper surface 21 and the lower surface 22 increases from the left side to the right side of the figure, with the thickness of the inclined base section 2 being smallest at the right end of the figure and largest at the left end. That is, in a plan view, the inclination direction of the upper surface 21 relative to the lower surface 22 is not inclined in the width direction, but is provided to follow the lateral direction.

[0022] In Figures 1, 3, and 4, the horizontal direction, which corresponds to the left-right direction in the figures, is aligned with the horizontal plane. The inclined base section 2 is positioned so that its lower surface 22 is aligned with the horizontal direction, and its upper surface 21 is positioned so that it slopes upward in the vertical direction as it moves towards the left side of the figure. In detail, the upper surface 21 is inclined at an angle of 3 degrees relative to the lower surface 22. The thickness of the inclined base portion 2 is smallest at the right end and largest at the left end in the plan view shown in Figure 2. Therefore, the direction of the inclination of the upper surface 21 relative to the lower surface 22 (inclination direction) coincides with the left-right direction in Figure 2. That is, in the plan view, the inclination direction of the inclined base portion 2 coincides with the direction of each of the linear edges 24 formed along the left-right direction in the figure, and each edge 24 functions as an indicator portion 23 that allows for an intuitive understanding of the inclination direction of the inclined base portion 2. In other words, the indicator portion 23 is formed to indicate the direction of the inclination of the upper surface 21 relative to the lower surface 22 of the inclined base portion 2.

[0023] In a base member such as the inclined base section 2, where the top and bottom surfaces are arranged in an inclined manner, the direction of the inclination can be determined by visually observing it from the width direction perpendicular to the vertical direction. However, if the shape in plan view is formed as a circle or the like, it is difficult to accurately determine the direction of the inclination in plan view or bottom view. In particular, when the angle of inclination between the top and bottom surfaces is small, it is necessary to observe the base member thoroughly from all sides in order to accurately determine the direction of the inclination. The base 1 shown in Figures 1-3 has a directional section 23 formed on the inclined base section 2, which allows for accurate determination of the inclination direction between the upper surface 21 and the lower surface 22, even when viewed from above, such as in a plan view, or from the bottom view. This reduces directional errors when installing the base on a mounting surface.

[0024] As shown in Figures 1 and 3, the base 1 has the upper surface of the base plate 31 of the male screw base 3, which is positioned below the inclined base 2, in contact with the lower surface 22, and the base plate 31 and the inclined base 2 constitute the base portion 11. Furthermore, the male thread 35a of the male thread base portion 3 is inserted through the through hole 25 of the inclined base portion 2 and protrudes upward from the upper surface 21 to form the male thread portion 12. Since the male thread portion 35a is positioned to protrude perpendicularly to the substrate 31, it is positioned perpendicularly to the substrate 31 and the lower surface 22 of the inclined base portion 2, and inclined relative to the upper surface 21 of the inclined base portion 2.

[0025] Figure 5 is a front view showing one embodiment of the road marking body 5. The road marking body 5 comprises a column portion 51 and a base portion 55, and is formed by erecting the column portion 51 so as to protrude above the base portion 55. The column section 51 is formed as a cylindrical hollow columnar body and is made of thermoplastic polyurethane resin so as to have flexibility that allows it to bend elastically due to contact with a vehicle, etc., and then return to its original state. A reflective sheet 54 having retroreflective properties that reflects the irradiated light back towards the light source is attached to the outer surface of the column portion 51.

[0026] The base portion 55 is made of acrylonitrile-styrene-acrylate resin (ASA resin), which is harder than the column portion 51. A through hole 56 is formed in the base portion 55 near the center in a plan view, and the through hole 56 is located directly below the column portion 51. Figure 6 is a vertical end view of the area near the base portion 55 in Figure 5. A roughly cylindrical base portion 53 is provided at the lower end of the column portion 51, and this base portion 53 is attached to the base portion 55. Specifically, the column portion 51 is fixed to the base portion 55 by engaging an engaging portion (not shown) formed on the base portion 53 with an engaging portion (not shown) formed on the base portion 55, and by attaching a holding member 57 that maintains the engagement of each of the engaging portions.

[0027] The engagement of each of the aforementioned engaging parts can be released by removing the holding member 57, and the base portion 53 can be removed from the base portion 55. Figure 7 shows the base portion 55 and column portion 51 of Figure 6 separated. In Figure 7, the column 51 is removed from the base 55 by detaching the holding member 57 from the base 55 and then releasing the engagement of each engaging part. The column 51 can be attached to the base 55 by performing the reverse operation, as shown in Figure 6, and the road marking body 5 is provided so that the column 51 can be attached to and detached from the base 55.

[0028] Figure 8 is a longitudinal cross-sectional view showing the base 1 from Figure 3 fixed to the mounting surface G. The installation surface G in Figure 8 is a slope-like inclined surface that slopes upward in the vertical direction from left to right in the figure, and more specifically, it is inclined at an angle of 3 degrees with respect to the horizontal direction, which is the left-right direction in the figure. In Figure 8, the base 1 is positioned so that the inclination direction of the inclined base portion 2 aligns with the opposite direction of the inclination of the installation surface G, and the lower surface of the base portion 11 and the installation surface G are firmly fixed with adhesive. Specifically, only the male screw base portion 3 of the base 1 is fixed to the installation surface G by adhesive (not shown) applied to the lower surface of the substrate 31 which constitutes part of the base portion 11. That is, in Figure 8, the orientation of the inclined base portion 2 can be adjusted after the male screw base portion 3 has been adhesively fixed to the installation surface G, and the direction of the inclination of the inclined base portion 2 can be intuitively and accurately grasped by the indicator portion 23 and positioned in the orientation corresponding to the inclination of the installation surface G. On the other hand, if the indicator portion 23 is not formed on the inclined base portion 2, it is necessary to carefully observe the inclined base portion 2 in order to position the inclined base portion 2 in the orientation corresponding to the inclination of the installation surface G, which would result in extra work during the installation process. Furthermore, there is a risk that a discrepancy may occur between the direction of the inclination of the inclined base 2 and the direction of the inclination of the installation surface G, which may result in the orientation of the column 51 of the road marking body 5, which will be installed on the inclined base 2 as described later, being tilted significantly more than the vertical direction. Furthermore, the base 1 in Figure 8 is designed so that only the inclined base portion 2 can be removed from the male screw base 3 and replaced.

[0029] In Figure 8, the base 1 is formed such that the angle of inclination of the upper surface 21 relative to the lower surface 22 of the inclined base 2 is the same as the angle of inclination of the installation surface G with respect to the horizontal direction, and the inclination direction of the inclined base 2 is aligned with the opposite direction of the inclination of the installation surface G, so that the upper surface of the base 11 formed by the upper surface 21 is aligned with the horizontal direction. Furthermore, the male threaded portion 12 of the base 1 is positioned perpendicular to the substrate 31 which forms part of the lower surface of the base 11, and is positioned perpendicular to the mounting surface G. In other words, the male threaded portion 12 of the base 1 is not positioned perpendicular to the horizontal plane, but is inclined at an angle corresponding to the inclination of the mounting surface G with respect to the vertical direction.

[0030] Figure 9 shows the state in which the base portion 55 of the road marking body 5 shown in Figure 7 is attached to the base 1 shown in Figure 8. In Figure 9, the base portion 55 is placed on the upper surface 22 that constitutes the upper surface of the base portion 11, with the male threaded portion 12 of the pedestal 1 inserted through the through hole 56. The male threaded portion 12 is positioned at an angle with respect to the lower surface of the base portion 55 which is placed on the upper surface of the base portion 11, and is also inclined with respect to the direction of penetration of the through hole 56. The base portion 55 is fixed to the base 1 by a female threaded member 16 that is screwed onto the male threaded portion 12, with a spacer S and a washer member 15 attached to the male threaded portion 12.

[0031] Figure 10 shows one embodiment of the washer member 15, where (a) is a plan view and (b) is a front view. The washer member 15 is one of the components that make up the base 1, and is formed in a roughly plate shape with a rectangular upper surface 15a and a lower surface 15b, and has a circular through hole 15c in the center. The upper surface 15a and the lower surface 15b are not parallel but are arranged at an angle, and in the front view shown in Figure 10(b), the thickness increases from the right side to the left side of the figure. Specifically, the upper surface 15a and lower surface 15b of the washer member 15 are positioned at an angle corresponding to the inclination between the upper surface 21 and lower surface 22 of the inclined base portion 2, and more precisely, they are inclined at an angle of 3 degrees.

[0032] Figure 11 shows the female threaded member 16 and the washer member 15 from Figure 10 attached and fixed to the male threaded portion 12 of the base 1 from Figure 9. In Figure 11, a spacer S is attached to the male threaded portion 12 of the base 1 to fill the gap between the male threaded portion 12 and the through hole 56. The spacer S is cylindrical in shape, having an outer shape corresponding to the inner surface of the through hole 56 of the base portion 55 and a hollow portion corresponding to the outer diameter of the male threaded portion 12, and is made of elastically deformable ethylene propylene diene rubber (EPDM). By installing the spacer S, the gap between the through hole 56 and the male threaded portion 12 is sealed, suppressing misalignment and looseness of the base portion 55 fixed by the male threaded portion 12. Furthermore, since the spacer S is made of an elastically deformable material, it can effectively seal the gap between the through hole 56 and the male threaded portion 12, which are arranged at an angle to each other, thereby suppressing misalignment and looseness between the base 1 and the road marking body 5 even when the road marking body 5 is subjected to vibration or contact by a vehicle.

[0033] In Figure 11, the washer member 15 is mounted with its lower surface 15b resting on and in contact with the base portion 55 near the opening of the through hole 56, so that the direction of the inclination of the lower surface 15b relative to the upper surface 15a is in the opposite direction to the direction of the inclination of the upper surface 21 relative to the lower surface 22 of the inclined base portion 2. By mounting the washer member 15 in this way, the upper surface 15a of the washer member 15 is positioned parallel to the lower surface of the substrate 31 that constitutes the lower surface of the base portion 11, and is positioned perpendicular to the axial direction of the male screw portion 12.

[0034] The female threaded member 16 in Figure 11 is a hexagonal nut, which abuts against the upper surface 15a of the washer member 15 and is screwed onto the male threaded portion 12. Since the female threaded member 16 abuts against the upper surface 15a of the washer member 15, which is positioned perpendicular to the axial direction of the male threaded portion 12, the entire lower surface of the female threaded member 16, rather than just a part of it, abuts against the washer member 15. That is, the fastening force between the female threaded member 16 and the male threaded portion 12, which has its entire lower surface in contact, can be effectively transmitted to the base portion 55 via the washer member 15, and the base portion 55 can be firmly fixed to the base 1. In addition, by attaching the washer member 15, a part of the female threaded member 16 does not abut against the base portion 55, thus preventing damage to the base portion 55. Furthermore, the female threaded member 16 is not limited to a hexagonal nut; other nut members such as flange nuts or cap nuts may be used, or other members having female threads that can be screwed onto the male threaded portion 12 may be used.

[0035] Figure 12 shows the state in which the column portion 51 is attached to the base portion 55 of Figure 11. As shown in Figure 12, the column portion 51 restricts its vertical movement by engaging the engagement portion (not shown) formed on the base portion 53 with the engagement portion (not shown) formed on the base portion 55. The column portion 51 is fixed to the base portion 55 by attaching the holding member 57 to the base portion 55, thereby maintaining the engagement of each of the engaging portions.

[0036] Figure 13 shows the state in which the retaining member 57 that maintains the engagement between the column portion 51 and the base portion 55 of Figure 12 is attached, and Figure 14 is a front view of the road marking body 5 of Figure 13, which is erected by fixing the column portion 51 to the base portion 55. The road marking body 5 shown in Figures 13 and 14 has a column portion 51 detachably attached to the base portion 55 in the same way as the road marking body 5 shown in Figures 6 and 7, and the column portion 51 can be removed from the base portion 55 by removing the holding member 57 from the base portion 55.

[0037] The road markings 5 ​​shown in Figures 13 and 14 are fixed to the base 1 by contacting the lower surface of the base 55 with the upper surface 21 which is positioned horizontally, and the column portion 51 is erected in the vertical direction. Furthermore, since the road marking body 5 is fixed to the base portion 55 using a single male screw portion 12 provided in the center of the base 1, the work of fixing it to the base 1 is easy. Also, since the base portion 55 can be removed from the base 1 by unscrewing the female screw member 16 from the male screw portion 12, the work of replacing the installed road marking body 5 is easy. Moreover, with the road marking body 5 removed, the inclined base portion 2 of the base 1 can be removed and replaced.

[0038] Figure 15 is a front view showing another embodiment of the base 1 according to the present invention, Figure 16 is a plan view of Figure 15, and Figure 17 is a cross-sectional view AA of Figure 16. The main difference between the base 1 shown in Figures 15-17 and the base 1 shown in Figures 1-4 is that the base 31 of the male screw base 3 is fixed by contacting the upper surface 21 of the inclined base 2, rather than the lower surface 22. Specifically, the base 1 shown in Figures 15-17 includes an inclined base portion 2 and a male screw base portion 3, similar to the base 1 shown in Figures 1-4. The male screw base portion 3 shown in Figures 15-17 is formed in the same shape as the inclined base portion 2 and male screw base portion 3 shown in Figures 1-4. Furthermore, the inclined base portion 2 shown in Figures 15-17 is formed in the same shape as the inclined base portion 2 shown in Figures 1-4, except that it does not have a through hole 25.

[0039] The base 1 shown in Figures 15-17 has a male screw base 3 positioned vertically above the inclined base 2, and is irremovably bonded and fixed to the upper surface 21 of the inclined base 2 by adhesive applied to the lower surface of the substrate 31. The base 1 shown in Figures 15-17 consists of a base plate 31 and an inclined base portion 2, with a male threaded portion 12 protruding vertically upward from the center of the base 11, formed by a bolt 35 on the male threaded base portion 3. The male screw portion 12 is positioned perpendicular to the upper surface of the base portion 11, which is made up of a substrate 31 fixed to the upper surface 21 of the inclined base portion, and is positioned inclined with respect to the lower surface of the base portion 11, which is made up of the lower surface 22 of the inclined base portion 2.

[0040] Figure 18 is a longitudinal cross-sectional view showing the base 1 of Figure 17 fixed to the mounting surface G. The mounting surface G in Figure 18 is a slope-like inclined surface that slopes upward in the vertical direction from left to right in the figure, similar to the aforementioned mounting surface G in Figure 8, and is inclined at an angle of 3 degrees with respect to the horizontal direction. The base 1 in Figure 18 is positioned similarly to the base 1 shown in Figure 8, with the direction of inclination of the upper surface 21 relative to the lower surface 22 of the inclined base 2 aligned with the opposite direction of the inclination of the installation surface G. The lower surface 22 of the inclined base 2, which constitutes the lower surface of the base 11, and the installation surface G are firmly fixed together with adhesive. The base 1 can be intuitively and accurately grasped by the indicator section 23 to determine the inclination direction of the inclined base section 2, and then positioned and installed on the installation surface G in the orientation corresponding to the inclination. On the other hand, if the inclined base 2 does not have a directional indicator 23, it is necessary to carefully observe the inclined base 2 in order to position it in a direction corresponding to the inclination of the installation surface G, which adds extra work to the installation process. Furthermore, there is a risk that a discrepancy may occur between the inclination direction of the inclined base 2 and the inclination direction of the installation surface G, which could result in the orientation of the column 51 of the road marking body 5, which will be installed on the inclined base 2 (described later), being tilted significantly more than the vertical direction.

[0041] In Figure 18, the base 1 is formed such that the angle of inclination of the lower surface 22 relative to the upper surface 21 of the inclined base 2 is the same as the angle of inclination of the installation surface G with respect to the horizontal direction, and the inclination direction of the inclined base 2 is aligned with the opposite direction of the inclination of the installation surface G, so that the upper surface of the base 11 made of the substrate 31 is aligned with the horizontal direction. Furthermore, the male screw portion 12 of the base 1 is positioned perpendicular to the upper surface of the base portion 11 and is positioned to face a vertical direction perpendicular to the horizontal direction.

[0042] Figure 19 shows the state in which the base portion 55 of the road marking body 1 shown in Figure 6 is attached to the base 1 shown in Figure 18. The base portion 55 in Figure 19 is placed on the upper surface of the substrate 31 that constitutes the upper surface of the base portion 11, with the male threaded portion 12 of the base 1 inserted through the through hole 56, similar to the base portion 55 in Figure 9. The male threaded portion 12 is positioned perpendicular to the lower surface of the base portion 55 that is placed on the upper surface of the base 11, and is positioned parallel to the direction of penetration of the through hole 56. The base portion 55 is fixed to the base 1 by a female threaded member 16 that is screwed onto the male threaded portion 12, with a spacer S and a washer P attached to the male threaded portion 12.

[0043] Figure 20 shows the state in which the washer P and female thread member 16 are attached to and fixed to the male thread portion 12 of the base 1 shown in Figure 19. The spacer S shown in Figure 20 is the same as the spacer S shown in Figure 11, and is installed to fill the gap between the male threaded portion 12 of the base 1 and the through hole 56. By installing the spacer S, the gap between the through hole 56 and the male threaded portion 12 is sealed, which suppresses misalignment and looseness of the base portion 55 fixed by the male threaded portion 12 even when the road marking body 5 is subjected to vibration or contact by a vehicle.

[0044] The washer P in Figure 20 is a flat washer, specifically a so-called flat washer. The washer P is positioned with its lower surface resting on and in contact with the base portion 55 near the opening of the through hole 56, similar to the washer member 15, and the female thread member 16 is in contact with its upper surface. The female thread member 16 shown in Figure 20 is the same as the female thread member 16 shown in Figure 11 and is formed from a hexagonal nut.

[0045] The base portion 55 shown in Figure 20 can be fitted with the column portion 51 in the same manner as described in Figures 11-14, and the holding member 57 can be attached to it, thereby allowing the road marker body 5, which includes the column portion 51, to be installed on the base 1. Furthermore, the column portion 51 of the road marker body 5 is positioned to extend in a vertical direction perpendicular to the horizontal plane, similar to the road marker body 5 shown in Figures 13 and 14.

[0046] The road marking body 5, which is constructed by attaching a column portion 51 to a base portion 55 as shown in Figure 20, and the road marking body 5 shown in Figures 13 and 14, have one male screw portion 12 formed near the center of the base portion 11 of the pedestal 1, and the base portion 55 of the road marking body 5 is attached using this male screw portion 12, making the installation of the road marking body 5 easy.

[0047] Furthermore, the base 1 shown in Figures 1-3 and Figures 15-17 have a directional indicator 23 that allows for the determination of the direction of the inclination of the upper surface relative to the lower surface of the base 11. This allows for an intuitive and accurate determination of the inclination of the base 11, thereby reducing directional errors during installation on the mounting surface G. Furthermore, since the indicator section 23 is formed in a position visible from the top or bottom view of the base 1, the direction of the inclination of the base 11 can be intuitively and accurately grasped by viewing it from below or above in the vertical direction, thereby reducing directional errors when installing it on the installation surface G. In particular, by forming the indicator section 23 in a position visible from above in the vertical direction of the base 1, the installation work of the base 1 can be made easier.

[0048] Figure 21 is a front view showing another embodiment of the inclined base portion 2B of the base 1 according to the present invention, and Figure 22 is a plan view of Figure 21. The inclined base section 2B is a plate-like body with a flat upper surface 21 and a lower surface 22 arranged at an inclination, similar to the inclined base section 2 shown in Figures 1 to 4, and has a circular through-hole 25 that penetrates vertically through the center. In Figures 21 and 22, the thickness of the inclined base section 2B is smallest at the right end of the figure and largest at the left end of the figure. The inclined base section 2B is formed of EPDM, similar to the inclined base section 2 shown in Figures 1-4, but is not limited to this. It can be formed by selecting or combining synthetic rubber, natural rubber, elastomers such as polyurethane or polyvinyl chloride, or by using other synthetic resins or hard materials such as metal.

[0049] The inclined base portion 2B is formed in a roughly circular, disc-like shape in plan view, and a directional portion 23B is formed on its upper surface 21. The directional portion 23B is a recess formed on the upper surface 21, and is formed as a straight, narrow groove, so as to be aligned with the direction of inclination of the upper surface 21 relative to the lower surface 22. That is, since the directional portion 23B is provided to indicate the inclination direction of the inclined base portion 2B, the inclination direction of the inclined base portion 2B can be intuitively and accurately grasped by checking the orientation of the directional portion 23B. The indicated portion 23B is formed as a solid line that traces the diameter across the entire circular upper surface 21, but it may also be formed on only a part of the upper surface 21, or it may be formed as a dotted line. Furthermore, although the indicator portion 23B is formed to align with the direction of the inclination of the upper surface 21 relative to the lower surface 22, the indicator portion 23B may also be formed to align perpendicular to this inclination direction so that the inclination direction can be indirectly grasped from the orientation of the indicator portion 23B. However, as shown in Figure 22, forming the indicator portion 23B to align with the inclination direction is preferable because it allows for a more intuitive grasp of the inclination direction of the inclined base portion 2B.

[0050] Figure 23 is a front view showing another embodiment of the inclined base portion 2C of the base 1 according to the present invention. The inclined base portion 2C differs from the inclined base portion 2B shown in Figures 21 and 22 only in the configuration of the square portion 23C formed on the upper surface 21. Specifically, the inclined base portion 2C shown in Figure 23 is a circular plate-like body with a flat upper surface 21 and a lower surface 22 arranged at an incline, similar to the inclined base portion 2B, and has a circular through-hole 25 that penetrates vertically through the center. The thickness of the inclined base portion 2C is smallest at the right end in the figure and largest at the left end in the figure.

[0051] The inclined base portion 2C has a concave indicator portion 23C formed on its upper surface 21. As shown in Figure 23, the indicator portion 23C is not a straight line, but is formed as an arrow-shaped mark indicating the direction of the inclination of the upper surface 21 relative to the lower surface 22. An arrow-shaped indicator portion 23Ca is formed at the left end of the figure where the thickness of the inclined base portion 2C is maximum, and an arrow-shaped indicator portion 23Cb is formed at the right end of the figure where the thickness of the inclined base portion 2C is minimum, and is smaller in size than the indicator portion 23Ca. Since the indicator sections 23Ca and 23Cb are formed in the shape of arrows indicating the direction of inclination, the inclination direction of the inclined base section 2C can be intuitively and accurately grasped by checking the direction indicated by each indicator section 23Ca and 23Cb. Furthermore, the inclination direction of the inclined base section 2C can be determined from the arrangement of the indicator section 23Ca formed at the position with the greatest thickness and the indicator section 23Cb formed at the position with the least thickness.

[0052] The directional sections 23Ca and 23Cb formed on the inclined base section 2C are each formed in the shape of arrows, but they may also be formed in other shapes that indicate direction, such as triangles. Alternatively, they may be formed in shapes that do not indicate direction, such as circles, but forming them in shapes that indicate direction, such as arrows or triangles, is preferable because it allows for a more intuitive understanding of the direction of the inclination of the upper surface 21a relative to the lower surface 22. Alternatively, each of the indicated portions 23Ca and 23Cb may be formed to be the same size. Alternatively, only one of the two indicated portions 23Ca and 23Cb, which are formed at the locations where the thickness of the inclined base portion 2C is maximum and minimum, may be formed. Furthermore, when the direction-indicating portion 23C is formed in the shape of an arrow or a triangle, which has a function of indicating direction, the direction-indicating portion 23C may be formed at a location other than the point where the thickness of the inclined base portion 2C is maximum or minimum.

[0053] The square-shaping sections 23B and 23C are formed in a concave shape on the upper surface 21 of the inclined base section 2B and 2C, but are not limited to this. They may be formed in a convex shape, or formed by printing or painting on the upper surface 21, or formed by attaching a sheet-like display body depicting the square-shaping sections 23B and 23C, or by other methods. Furthermore, although the square-shaped portions 23B and 23C are formed only on the upper surface 21 of the inclined material portions 2B and 2C, they may also be formed on both the upper surface 21 and the lower surface 22.

[0054] Each of the inclined base sections 2B and 2C shown in Figures 21 to 23 can be combined with the male screw base section 3 shown in Figures 1 to 4 and used in the same manner as the base 1 shown in Figures 1 to 4 and the base 1 shown in Figures 15 to 17, allowing the road marking body 5 to be installed by being positioned between the installation surface G and the road marking body 5.

[0055] Furthermore, the inclined base portion 2 shown in Figures 1 to 4, and the inclined base portions 2B and 2C shown in Figures 21 to 23, can be used as bases 1 for installing the road marking body 5 without being combined with the male screw base portion 3. As an example, the indicator portion 23 of the inclined base portion 2 shown in Figures 1 to 4 may be positioned in a direction corresponding to the inclination direction of the installation surface G, fixed to the installation surface G with adhesive applied to the lower surface 22, and further fixed to the upper surface 21 and the base portion 55 of the road marking body 5 with adhesive. As another example, an anchor nut member having a female threaded portion may be embedded and fixed in the installation surface G, and an inclined base portion 2 with a square-shaped portion 23 positioned in a direction corresponding to the inclination direction of the installation surface G may be placed directly above it. The male threads of a male threaded member such as a bolt attached to the base portion 55 of the road marking body 5 may be inserted through the through hole 25 of the inclined base portion 2 and screwed into the anchor nut member, thereby installing the inclined base portion 2 and the road marking body 5 on the installation surface G. Alternatively, the road marking body 5 may be installed on the installation surface G using the inclined base 2B or inclined base 2C in the same manner as the inclined base 2 illustrated above.

[0056] Furthermore, the installation structure of the base 1 and the road marking body 5 using the base 1 according to the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the inclined base portion 2C shown in Figure 23 has the indicator portion 23Ca and the indicator portion 23Cb formed on the upper surface 21, but it is not limited to this. For example, the indicator portion 23Ca and the indicator portion 23Cb may be formed on the side surface in the width direction in Figure 23. Even when the indicator portion 23Ca and the indicator portion 23Cb are formed on the side surface of the inclined base portion 2C in this way, they can be viewed from diagonally above the inclined base portion 2C, so it is possible to accurately grasp the inclination direction of the inclined base portion 2C. However, as shown in Figure 23, forming the indicator portion 23Ca and the indicator portion 23Cb on the upper surface 21 makes them easier to see from above, so it is preferable to be able to grasp the inclination direction of the inclined base portion 2C more intuitively and accurately.
