Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, this mounting member includes a functional member that performs a predetermined display and a support layer that supports the functional member, and may also include a protective layer that covers the functional member depending on the application. Each layer is adhered to each other. Further, when such a mounting member is attached to a floor surface, a road surface, or a ground surface, it is fixed using an adhesive or the like.

[0005] However, after the mounting members are installed, friction from heavy objects such as car tires can cause the protective layer to move in the shear direction relative to the support layer, resulting in the protective layer peeling off. To prevent this, it is possible to paint directly onto the floor, road, or ground surface, but this is only applicable when the display content is fixed and cannot be used for displays that change. Furthermore, when painting is no longer needed, removing or repainting the paint is both time-consuming. In particular, outdoor painting work is highly susceptible to weather conditions, both during the painting process and drying time. Therefore, both installation and removal work are easily affected by the weather.

[0006] Therefore, the present invention aims to provide a mounting structure, mounting unit, clamping and fixing member, fixing method, and manufacturing method for mounting member that are less prone to peeling between constituent members and allow for easy installation and removal.

[0029] For the sake of explanation, we will define any direction in the horizontal plane as the X direction, any direction in the horizontal plane that is perpendicular to the X direction as the Y direction, and any direction perpendicular to the horizontal plane as the Z direction.

[0030] As shown in Figure 1, the mounting unit 2 is attached to the road surface of the asphalt pavement R1 (member to be attached) of the parking space A1 set up in the parking lot P1.

[0031] As shown in Figures 2-3, the mounting unit 2 comprises a mounting member 10 that can be placed on the asphalt pavement R1, and a mounting structure 20 that can attach the mounting member 10 to the asphalt pavement R1.

[0032] (Mounting member) As shown in Figures 2-4, the mounting member 10 is plate-shaped and formed in a square shape with sides extending in the X and Y directions. The mounting member 10 comprises a surface layer 11 and a support layer 12 that supports the surface layer 11. Figure 2(B) is a front view of the mounting unit 2. The left side view, right side view, and rear view of the mounting unit 2 are the same shape as the front view and are therefore omitted.

[0033] The surface layer 11 is plate-like and formed in a square shape with sides extending in the X and Y directions. The Z direction is the thickness direction of the surface layer 11. The surface layer 11 is transparent. A predetermined identifier S1 (dashed line in the figure) is applied to the back surface 11B of the surface layer 11, so that the printed portion functions as a functional member. Therefore, the printed portion can be seen from the surface (Figure 2(A)).

[0034] The support layer 12 is plate-shaped and formed in a square shape with sides extending in the X and Y directions. The lengths of the sides in the X and Y directions of the support layer 12 are approximately equal to those of the surface layer 11. The Z direction is the thickness direction of the support layer 12. The support layer 12 is placed on the pavement surface of the asphalt pavement R1. It is preferable that the support layer 12 is made of a material that is more easily deformable than the surface layer 11. This makes it possible to convert the kinetic energy received by the surface layer 11 into deformation energy of the support layer 12, thereby suppressing damage to the surface layer 11 due to external kinetic energy. In addition, if there are irregularities on the pavement surface of the asphalt pavement R1, the irregularities can be absorbed by the deformation of the support layer 12. Furthermore, when the mounting member 10 is fixed to the pavement surface of the asphalt pavement R1 while the support layer 12 is deformed to the extent that it can absorb irregularities, positional displacement in the surface direction of the pavement surface of the asphalt pavement R1 becomes less likely.

[0035] Examples of materials used to form the surface layer 11 include synthetic resins. Preferably, the synthetic resin used to form the surface layer 11 is a thermoplastic resin, a thermosetting resin, a thermosetting elastomer, or a thermoplastic elastomer.

[0036] Suitable thermoplastic resins include general-purpose plastics, engineering plastics, and super engineering plastics.

[0037] Common plastics include polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene (AS), methyl methacrylic (PMMA), polyvinylidene chloride (PVDC), and polyethylene terephthalate (PET).

[0038] Engineering plastics include polyamide (PA), polyacetal (POM), polycarbonate (PC), polyphenylene ether (PPE), polybutylene terephthalate (PBT), ultra-high molecular weight polyethylene, and polyvinylidene fluoride (PVDF).

[0039] Other examples of super engineering plastics include polysulfone (PSU), polyethersulfone (PES), polyphenylene sulfide (PPS), polyarylate (PAR), polyamide-imide (PAI), polyetherimide (PEI), polyetheretherketone (PEEK), polyimide (PI), and polytetrafluoroethylene (PTFE).

[0040] Examples of thermosetting resins include phenolic resin (PF), urea resin (UF), melamine resin (MF), unsaturated polyester (UP), epoxy resin (EP), silicone resin (SI), and polyurethane (PUR).

[0041] As thermosetting elastomers, it is preferable to use, for example, natural rubber, silicone rubber, isoprene rubber, urethane rubber, ethylene propylene rubber, etc.

[0042] As the thermoplastic elastomer, it is preferable to use olefin-based thermoplastic elastomers, urethane-based thermoplastic elastomers, styrene-based thermoplastic elastomers, etc.

[0043] Examples of materials used to form the support layer 12 include synthetic resins. The synthetic resin used to form the support layer 12 can be any material that can form shaft through holes using a predetermined drilling device, and is preferably a thermoplastic resin, thermosetting resin, rubber, or elastomer. Details of the thermoplastic resin or thermosetting resin are the same as those for the material used to form the surface layer 11. The synthetic resin used to form the support layer 12 is preferably a material that is more easily deformed than the surface layer 11, or a material that is softer than the material used to form the surface layer 11.

[0044] The surface layer 11 and the support layer 12 are fixed together by an adhesive. Any known adhesive material can be used as the forming material of the adhesive; for example, an organic adhesive (thermoplastic resin, thermosetting resin, rubber, elastomer, etc.) can be used. The area to which the adhesive is applied may be the entire portion where the back surface 11B of the surface layer 11 and the surface 12A of the support layer 12 are in contact, or it may be the outer edge 10G (Figure 2) of the portion where the back surface 11B of the surface layer 11 and the surface 12A of the support layer 12 are in contact. The support layer through-hole formation position 24 or the shaft through-hole 24X, which will be described later, may be located within the outer edge 10G. This makes it difficult for foreign matter (moisture, oil, dirt, etc.) to penetrate from the outer wall surface of the mounting member 10 or the wall surface of the shaft through-hole 24X. As a result, adverse effects caused by the intrusion of foreign matter, such as peeling of the surface layer 11 and the support layer 12, and contamination and deterioration of the surface layer 11 and the support layer 12, can be suppressed.

[0045] (Mounting structure) As shown in Figures 4-5, the mounting structure 20 includes a connecting bolt 21 that can connect the mounting member 10 to the asphalt pavement R1 by penetrating the mounting member 10, a flat washer 22 (clamping fixing member), a surface layer through hole 23 (clamping fixing member insertion part) formed in the surface layer 11, and a support layer through hole formation position 24 (shaft through hole formation position) formed in the support layer 12.

[0046] (Connecting bolts) The connecting bolt 21 comprises a head 21A and a shaft 21B. The shaft 21B is formed in a cylindrical shape and extends straight in a predetermined direction (axis AX). The head 21A is provided on one side of the shaft 21B and protrudes radially outward with respect to the axis AX of the shaft 21B.

[0047] (Flat washer) As shown in Figures 4-6, the flat washer 22 is formed in a disc shape, with a washer hole 22X (through hole) in its center. The Z direction is the thickness direction of the flat washer 22. The washer hole 22X of the flat washer 22 is sized to allow the shaft portion 21B of the connecting bolt 21 to pass through, while restricting the passage of the head portion 21A. The inner edge portion 22N of the flat washer 22 (periphery of the washer hole 22X) extends toward the axis AX side of the head portion 21A of the connecting bolt 21. The outer edge portion 22G of the flat washer 22 protrudes radially outward from the head portion 21A of the connecting bolt 21, with reference to the axis of the shaft portion 21B. Here, the portion of the flat washer 22 from the inner edge portion 22N to the outer edge portion 22G becomes the clamping portion 22C.

[0048] (Surface layer through hole) The surface through-holes 23 are set at the four corners of the surface 11A of the surface layer 11 in a plan view (Figure 2). Surface through-holes 23X into which flat washers 22 can be inserted are formed in the surface through-holes 23 (Figures 4-5). The surface through-holes 23X extend in the Z direction from the surface to the back surface of the surface layer 11. As a result, the surface 12A of the support layer 12 is exposed through the surface through-holes 23X (Figure 5).

[0049] (Support layer through hole formation position) As shown in Figures 2 and 7, the support layer through-hole formation positions 24 are set at the four corners of the surface 12A of the support layer 12 when viewed from the Z direction, i.e., in a plan view. As shown in Figures 7 and 8, the support layer through-hole formation positions 24 are exposed in the portion of the surface 12A of the support layer 12 that is exposed from the surface through-hole 23X. In the fixing method 100 described later, by using a predetermined drilling device from the surface 10 side, a shaft through-hole 24X is formed at the support layer through-hole formation position 24, through which the shaft portion 21B of the connecting bolt 21 can pass (Figure 5). The shaft through-hole 24X extends in the Z direction from the surface 12A of the support layer 12 to the ground.

[0050] As shown in Figure 9, the flat washer 22 can be inserted into the surface through-hole 23X with the washer hole 22X opening in the Z direction. As a result, when the flat washer 22 is inserted into the surface through-hole 23X, the outer edge 22G of the flat washer 22 approaches the wall surface 23Y (wall surface of the surface layer 11) of the surface through-hole 23X, and the shaft through-hole 24X is exposed from the washer hole 22X (Figure 5).

[0051] In other words, when the outer diameter of the head of the connecting bolt 21 is D21A, the outer diameter of the shaft of the connecting bolt 21 is D21B, the outer diameter of the flat washer 22 is D22G, the inner diameter of the flat washer 22 is N22G, and the diameter of the surface through hole 23X is D23X, the following relationship holds. D23X > D22G > D21A >D22N> D21B

[0052] Next, we will explain the fixing method 100.

[0053] As shown in Figure 10, the fixing method 100 comprises a placement step S1, a hole forming step S2, a clamping fixing member placement step S3, and a connecting bolt penetration step S4.

[0054] (Placement step) In the placement step S1, the placement member 10 is placed on the asphalt pavement R1 (Figure 8).

[0055] (Pore formation step) In hole formation step S2, a drilling device positioned on the surface layer 11 side is used to apply a rotating drill bit to the support layer through-hole formation position 24 (Figure 8) that is exposed from the surface through-hole 23X. This forms a shaft through-hole 24X at the support layer through-hole formation position 24 (Figure 5). The shaft through-hole 24X extends in the Z direction from the support layer through-hole formation position 24 (surface 12A of the support layer 12) into the ground.

[0056] (Step for placing clamping and fixing member) In step S3, the clamping and fixing member is placed, and flat washers 22 are inserted into the four surface through holes 23X (Figure 9). The flat washers 22 are then placed on the surface 12A of the support layer 12 that is exposed from each surface through hole 23X. In plan view, the shaft through hole 24X is exposed from the washer hole 22X of the flat washer 22, and the outer edge 22G of the flat washer 22 approaches the wall surface 23Y of the surface through hole 23X (Figure 6).

[0057] (Connecting bolt through step) In the connecting bolt penetration step S4, the connecting bolt 21 is passed through the shaft through hole 24X (Figure 4). Then, the flat washer 22 and the support layer 12 are sandwiched between the head 21A of the connecting bolt 21 and the asphalt pavement R1 (Figure 11). As a result, the movement of the flat washer 22 and the support layer 12 in the Z direction is restricted, as is their movement in the XY plane.

[0058] In this way, the mounting member 10 can be fixed to the asphalt pavement R1 by penetrating the connecting bolt 21 into the ground until the flat washer 22 is sandwiched between the head 21A of the connecting bolt 21 and the asphalt pavement R1. At this time, the outer edge 22G of the flat washer 22 approaches the wall surface 23Y of the surface penetration hole 23X. Therefore, even if the surface layer 11 tries to move in the XY plane direction (shear direction) relative to the support layer 12 due to external force, the outer edge 22G of the flat washer 22 engages with the wall surface 23Y of the surface penetration hole 23X, making it difficult for the surface layer 11 to peel off from the support layer 12. Since the mounting member 10 is fixed to the asphalt pavement R1 etc. using connecting bolts 21, it can be done simply without being affected by weather conditions such as painting.

[0059] In addition, in the connecting bolt penetration step S4, it is preferable that the head 21A of the connecting bolt 21 is flush with the surface 11A of the surface layer 11, or recessed on the back surface 11B side relative to the surface 11A (Figure 4).

[0060] In the above embodiment, the mounting structure 20 had a support layer through-hole formation position 24 (shaft through-hole formation position) formed in the support layer 12. However, the present invention is not limited to this, and instead of the support layer through-hole formation position 24 formed in the support layer 12, a shaft through-hole 24X may be formed in the support layer 12. In this case, the hole formation step S2 may be omitted in the fixing method 100 shown in Figure 10. That is, the fixing method 100 only requires the placement step S1, the clamping fixing member placement step S3, and the connecting bolt penetration step S4.

[0061] In the above embodiment, the formation positions of the surface through-holes 23 are set at the four corners of the surface 11A of the surface layer 11 in a plan view. However, the present invention is not limited to this, and as shown in Figure 12, they may be set in the middle or central part of the four sides of the square-shaped surface layer 11 in a plan view.

[0062] In the above embodiment, one flat washer 22 was inserted into the surface through hole 23X, but the present invention is not limited thereto, and multiple flat washers 22 may be inserted into the surface through hole 23X in an overlapping manner (Figure 13).

[0063] In the above embodiment, a flat washer 22 with a constant thickness was inserted as a clamping and fixing member, but the present invention is not limited to this, and a spring washer or the like may be used in combination.

[0064] Furthermore, although a flat washer 22 with a constant thickness was used as the clamping and fixing member in the above embodiment, a washer 122 as shown in Figure 14 may also be used. The washer 122 is circular in shape when viewed from above and from below. Preferably, the washer 122 is cylindrical with axis AX as its center. The washer 122 has a circular top surface 122U, and a cylindrical recess 122P is formed on the inner edge of the top surface. A circular washer hole 122X is formed in the center of the bottom surface of the recess 122P. Preferably, the circular washer hole 122X is formed with axis AX as its center. The shaft portion 21B of the connecting bolt 21 passes through the washer hole 122X. The recess 122P becomes a space for accommodating the head 21A of the connecting bolt 21. When the shaft portion 21B of the connecting bolt 21 is passed through the washer hole 122 such that all or part of the head 21A of the connecting bolt 21 is accommodated in the recess 122P, the outer edge portion 122G of the washer 122 approaches the wall surface 23Y of the surface through hole 23X. Preferably, the top surface 122U of the washer 122 is flush with the surface 11A of the surface layer 11, or recessed on the back surface 11B side of the surface 11A.

[0065] In the above embodiment, surface through-holes 23 are set at the four corners of the surface layer 11 in a plan view (Figure 2), but the present invention is not limited thereto, and notches 123 may be provided at the four corners of the surface layer 11 in a plan view (Figure 15). A fan-shaped notch 123X is formed in the notch 123. The formation of the notch 123X exposes the support layer through-hole formation position 24 in a plan view. When the flat washer 22 is placed on the surface 12A of the support layer 12, it is preferable that the outer edge 22G of the flat washer 22 is close to the wall surface 123Y of the notch 123. Alternatively, a flat washer 122 may be used instead of the flat washer 22 (Figure 15(C)). When the flat washer 122 is placed on the surface 12A of the support layer 12, it is preferable that the outer edge 122G of the flat washer 122 is close to the wall surface 123Y of the notch 123.

[0066] In the above embodiment, surface through-holes 23 are formed in the middle or central part of the four sides of the square-shaped surface layer 11 in a plan view (Figure 12), but the present invention is not limited thereto. For example, notches 223 may be provided in the middle or central part of the four sides of the square-shaped surface layer 11 (Figure 16). A semicircular notch 223X is formed in the notch 223. The formation of the notch 223X exposes the support layer through-hole formation position 24 in a plan view. When the flat washer 22 is placed on the surface 12A of the support layer 12, it is preferable that the outer edge 22G of the flat washer 22 is close to the wall surface 223Y of the notch 223. Alternatively, a flat washer 122 may be used instead of the flat washer 22 (Figure 16(C)). When the flat washer 122 is placed on the surface 12A of the support layer 12, it is preferable that the outer edge 122G of the flat washer 122 is close to the wall surface 223Y of the notch 223.

[0067] As another example, instead of the notches 223 formed in the middle or central parts of the four sides of the square-shaped surface layer 11, the outer edges 323 of the square-shaped surface layer 11 may be used (Figure 17). When the flat washer 22 is placed on the surface 12A of the support layer 12, it is preferable that the outer edges 22G of the flat washer 22 are close to the wall surface 223Y of the notches 223 (Figure 17(B)). Alternatively, instead of the flat washer 22, the washer 122 shown in Figure 14 may be used (Figure 17(C)). In this case, when the washer 122 is placed on the surface 12A of the support layer 12, the outer edges 122G of the washer 122 are close to the wall surface 323Y of the outer edges 323X of the surface layer 11.

[0068] As another example, while washers 22 and 122 were circular in plan view, the present invention is not limited to this. For example, a washer that is square in plan view, such as the washer 222 shown in Figure 18, may be used. As shown in Figure 18(B), the washer 222 may have a plate member 222B in which a through hole 222X is formed. When the washer 222 is placed on the surface 12A of the support layer 12, the outer edge 222G of the plate member 222B approaches the wall surface 323Y of the outer edge 323X of the surface layer 11. Note that washers 22 and 122 are not limited to being square in plan view, but may also be other quadrilaterals (rectangles, rhombuses, etc.), other polygons (triangles, pentagons, hexagons, etc.), circles, ellipses, etc.

[0069] Furthermore, as another example, as shown in Figure 18(C), the washer 222 may comprise a plate member 222B and an upright portion 222T provided at the end of the plate member 222B and extending in the Z direction. When the washer 222 is placed on the surface 12A of the support layer 12, the outer edge portion 222G of the upright portion 222T approaches the wall surface 323Y of the outer edge portion 323X of the surface layer 11.

[0070] In the above embodiment, a surface through-hole 23X extending from the surface 11A to the back surface 12B of the surface layer 11 was used as the clamping member insertion portion. However, the present invention is not limited to this, and any hole or recess capable of accommodating a clamping member such as a washer 22 may be used.

[0071] For example, as shown in Figure 19(A), a blind hole 523X may be formed as a recess capable of accommodating the clamping and fixing member, opening from the surface 11A of the surface layer 11 and extending to the middle of the surface layer 11 in the thickness direction (Z direction). When the flat washer 22 is placed on the bottom surface of the blind hole 523X, it is preferable that the outer edge 22G of the flat washer 22 is close to the wall surface 523Y of the blind hole 523X.

[0072] Furthermore, as shown in Figure 19(B), a blind hole 623X may be formed as a recess capable of accommodating the clamping and fixing member, opening from the surface 11A of the surface layer 11 and extending to the middle of the support layer 11 in the thickness direction (Z direction). In this case, multiple flat washers 22 may be arranged on top of each other at the bottom surface 623B of the blind hole 623X (Figure 13), or a washer 122 as shown in Figure 14 may be arranged. At this time, it is preferable that the outer edge 22G of the flat washer 22 and the outer edge 122G of the flat washer 122 are close to the wall surface 523Y of the blind hole 523X.

[0073] In the above embodiment, a clamping and fixing member having a through hole 21X through which the shaft portion 21B of the connecting bolt 21 can pass was used. However, the present invention is not limited to this, and a clamping and fixing member having a shaft engagement portion into which the shaft portion 21B of the connecting bolt 21 can engage may also be used.

[0074] For example, the clamping and fixing member 722 shown in Figure 20 comprises a plate member 722A formed in a semicircular shape in plan view, and a shaft engagement portion 722B provided in the center of the plate member 722A. The shaft engagement portion 722B is a semicircular notch into which the shaft portion 21B of the connecting bolt 21 can engage. The plate member 722A and the shaft engagement portion 722B are formed concentrically. In plan view, the clamping and fixing member 722 is positioned on the bottom surface of the surface through hole 23X (the surface 12A of the support layer 12) such that the semicircular notch (inner edge portion 722N) follows the shaft through hole 24X. At this time, the outer edge portion 722G of the clamping and fixing member 722 follows the wall surface 23Y of the surface through hole 23X. Subsequently, when the connecting bolt 21 is passed through the shaft through hole 24X, the clamping fixing member 722 and the support layer 12 are clamped between the head 21A of the connecting bolt 21 and the asphalt pavement R1. As a result, the movement of the clamping fixing member 722 and the support layer 12 in the Z direction is restricted, as is their movement in the XY plane. In this way, when the clamping portion 722C, from the inner edge 722N along the wall surface of the shaft through hole 24X to the outer edge 722G along the wall surface of the surface through hole 23X, is clamped between the head 21A of the connecting bolt 21 and the asphalt pavement R1, the wall surface of the outer edge 722G of the clamping fixing member 722 approaches the wall surface 23Y of the surface through hole 23X. Therefore, even if the surface layer 11 attempts to move relative to the support layer 12 in the XY plane direction (shear direction) due to an external force, the outer edge portion 722G of the clamping and fixing member 722 engages with the wall surface 23Y of the surface layer through hole 23X, making it difficult for the surface layer 11 to peel off from the support layer 12.

[0075] In the above embodiment, through-holes or notches are provided on the outer edge of the surface layer 11 in a plan view (for example, the four corners of the surface 11A of the surface layer 11, or the middle or central portion of the four sides of the surface layer 11 in a plan view), but the present invention is not limited thereto. As long as it does not contradict the spirit of the present invention, through-holes or notches may be provided on the inner edge of the surface layer 11 in a plan view.

[0076] In the above embodiment, the shape of the surface layer 11 and the support layer 12 in plan view was square, but the present invention is not limited to this, and other quadrilaterals (rectangles, rhombuses, etc.), other polygons (triangles, pentagons, hexagons, etc.), circles, ellipses, etc. may also be used.

[0077] In the above embodiment, the back surface 11B of the surface layer 11 and the surface surface 12 of the support layer 12 were bonded together using an adhesive, but the present invention is not limited thereto.

[0078] For example, as shown in Figure 21, instead of adhesive, or in conjunction with adhesive, rivets 113 that penetrate the surface layer 11 and the support layer 12, or fixing members 213 that sandwich the outer edge of the surface layer 11 and the outer edge of the support layer 12 may be used.

[0079] As another example, instead of an adhesive, or together with an adhesive, a recess 11P may be provided on the back surface 11B of the surface layer 11, and a protrusion 12T may be provided on the surface 12A of the support layer 12 that can engage with the recess 11P (Figure 22). This makes it less likely for misalignment in the XY plane to occur. Alternatively, instead of providing a recess 11P on the back surface 11B of the surface layer 11 and a protrusion 12T on the surface 12A of the support layer 12 that can engage with the recess 11P, a protrusion may be provided on the back surface 11B of the surface layer 11 and a recess on the surface 12A of the support layer 12 that can engage with the protrusion. It is preferable that the protrusion and recess be formed in a location other than the area on the surface 12A of the support layer 12 where the flat washer 22 is placed.

[0080] In the above embodiment, the back surface 11B of the surface layer 11 and the surface surface 12 of the support layer 12 were bonded together using an adhesive, but the present invention is not limited to this, and a tack may be used instead.

[0081] In the above embodiment, a printed identifier S1 was used as the functional member, but the present invention is not limited thereto, and a sheet-like display member 13 capable of displaying a predetermined information may also be used. The display member 13 may be a display member using LED elements, EL elements, or electronic paper. The display member 13 is disposed between the surface layer 11 and the support layer 12 (Figure 23). Furthermore, it is preferable that a housing recess 11BP capable of accommodating the display member 13 is provided on the back surface 11B side of the surface layer 11. Moreover, it is preferable that the back surface 13B of the display member 13 is provided so as to be flush with the back surface 11B of the surface layer 11.

[0082] In the above embodiment, asphalt pavement R1 was used as the member to be attached, but the present invention is not limited to this, and concrete pavement, gravel pavement, flooring material or ground may also be used, as well as walls or fences.

[0083] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. [Explanation of Symbols]
