Description

[Technical field]

[0001] The present invention relates to a signboard to be installed on a curb, and more particularly to a signboard having a sign portion made of a reflective material that is detachable from the installation surface. [Background technology]

[0002] There are both standing signs and freestanding signs, and they display information such as public notices, guidance and warnings regarding construction work, and advertisements.

[0003] Such methods of erecting or placing signs on roads occupy a large area of ​​roads, and measures to ensure public safety are also required. For example, weights can be attached to prevent the signs from scattering in bad weather. In addition, when reflective material is directly attached with adhesive or painted, this is based on the idea of ​​simply obtaining visibility, and other methods have not been taken into consideration.

[0004] As one measure to deal with this situation, Patent Document 1 discloses a curb stud in which a reflective material is attached directly to the top of the curb with an adhesive or the like to warn pedestrians and others of the danger. Patent Document 1 discloses a curb stud that is installed around the road to guide drivers' gaze and help them clarify the road alignment, and is characterized in that it is equipped with a retroreflector and the outer surface of the retroreflector is provided with a transparent resin layer that contains a phosphorescent pigment.

[0005] However, while the curb stud disclosed herein can be easily attached to the curb with adhesive, the undercut portions of curbs come in a wide variety of shapes, making them difficult to attach with adhesive, and the places where they can be attached are limited to flat surfaces such as the top surface of the curb. Moreover, if even a portion of the stud is damaged, the entire stud must be replaced, which is costly and requires consideration. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2005-273266 A Summary of the Invention [Problem to be solved by the invention]

[0007] SUMMARY OF THE PRESENT EMBODIMENT In view of the above problems, an object of the present invention is to provide a signboard which can be attached to a curbstone with fewer restrictions and which allows for easy replacement of only those parts which are frequently damaged.

[0008] In order to solve the above problems, the inventors of the present invention have intensively studied the structure of a signboard and the method of attaching it to a curb, and as a result have developed the present invention.

[0009] In order to solve the above problems, a signboard according to one aspect of the present invention has a sign surface that displays required information using a reflective material, and includes a sign material having a first sheet-like rubber magnet layer adhered to a surface opposite to the sign surface, and a joining means for the sign material on at least one of the side surface and top surface including at least the cut-off portion of the curb, the joining means being a second sheet-like rubber magnet layer joined by an adhesive layer provided on at least one of the side surface and top surface including at least the cut-off portion of the curb, and Sheet-like The rubber magnet layer and the second Sheet-like The marking material is characterized in that the marking material has a columnar portion having a height approximately equal to the total thickness of the rubber magnet layers, a base portion formed integrally with the columnar portion, an area larger than the columnar portion, and a height approximately equal to the thickness of the adhesive layer, and a female screw provided on the columnar portion, the columnar portion being disposed in a through hole connecting the marking material and the second sheet-like rubber magnet layer, the base portion being embedded in the adhesive layer, a first joining means, a male screw that screws into the female screw of the first joining means, a second joining means having a through hole in a portion that is exposed and not screwed into the female screw, and a locking pin that is approximately E-shaped and has a central protrusion that passes through the through hole.

[0010] In addition, a signboard according to one embodiment of the present invention is characterized in that the first sheet-like rubber magnet layer has a thickness of 0.8 to 2.8 mm, the second sheet-like rubber magnet layer has a thickness of 3.0 to 5.0 mm, and the adhesive layer has a thickness of 0.8 to 1.0 mm.

[0011] Furthermore, a signboard according to one embodiment of the present invention is characterized in that the opposing surfaces of the first sheet-shaped rubber magnet layer and the second sheet-shaped rubber magnet layer have interlocking projections and recesses formed thereon. Effect of the Invention

[0012] The signboard according to the present invention can be arranged to match at least one of the shapes of the side surface including at least the cut-off portion of the curbstone and the top surface, and displays predetermined information on the signboard. Since the signboard has a means for detachably joining the signboard surface, the signboard surface can be easily replaced and the area of ​​the road space occupied by the signboard itself can be reduced. The fact that the signboard surface can be replaced is important in terms of use in an environment where the signboard is easily damaged, such as a road curbstone.

[0013] In addition, in the signboard of the present invention, it is possible to provide the joining surface of the sheet-shaped rubber magnet that constitutes the joining means with irregularities that engage with each other, thereby making it possible to prevent misalignment between the joining surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing an example of a signboard according to the present invention attached to a slope of a curb, and Fig. 2 is a detailed view showing an example of a cross section of the signboard according to the present invention.

[0016] As shown in these figures, the marking material 1 is composed of a marking surface 1a and a first sheet-like rubber magnet layer 1b. The reflective material used for the marking surface 1a can be of any type, including retroreflective, diffuse reflective, and specular reflective, and a retroreflective reflector, which is widely used for road signs, is preferable.

[0017] Further, the sign material 1 is bonded to the surface of the curbstone 5 using a second sheet-like rubber magnet layer 2 bonded to the surface of the curbstone 5 by an adhesive layer 2a. The first sheet-like rubber magnet layer and the second sheet-like rubber magnet layer are made of rubber with magnet powder dispersed therein, and the magnet material is preferably a ferrite-based material from the standpoint of durability outdoors and cost.

[0018] Fig. 3 shows an example of the first joining means 3 shown in Fig. 1 and Fig. 2, where Fig. 3(a) is a plan view and Fig. 3(b) is a front cross-sectional view. Also, Fig. 4 shows an example of the second joining means 4 shown in Fig. 1 and Fig. 2, where Fig. 4(a) is a plan view and Fig. 4(b) is a front view.

[0019] The base 3b of the first joining means 3 is arranged so as to be embedded in the adhesive layer 2a as shown in Figure 2, and the columnar portion 3a is arranged in a through hole that connects the sign material 1, i.e., the sign surface 1a, the first sheet-like rubber magnet layer 1b, and the second sheet-like rubber magnet layer 2, and has a female screw 3c provided therein.

[0020] The second joining means 4 is provided with a male thread 4c that screws into the female thread 3c of the first joining means 3, and is disposed in a state in which the exposed portion 4a and the flange portion 4b protrude from the marking surface portion 1a, as shown in Fig. 2. Here, an example in which the flange portion 4b is exposed is shown, but the flange portion 4b does not have to be exposed.

[0021] Fig. 5 is a plan view showing an example of an E-shaped locking pin 6 according to the present invention. Fig. 6 is a perspective view showing the E-shaped locking pin 6 inserted into the through hole 4d of the second connecting means 4. As shown here, the horizontal area of ​​the E-shaped pin 6 is larger than the horizontal area of ​​the flange portion 4b of the second connecting means 4, so that the marking material 1 can be prevented from moving upward in the figure and coming off the surface of the curbstone 5.

[0022] FIG. 7 is a perspective view showing a state in which a convex portion 1c and a concave portion 2c that engage with each other are formed on the opposing surfaces of the first sheet-shaped rubber magnet layer 1b and the second sheet-shaped rubber magnet layer 2. When using a rubber magnet, it is not difficult to impart such unevenness by hot pressing using a mold before the vulcanization process, and the engagement of the unevenness can suppress the positional deviation of the first sheet-shaped rubber magnet layer 1b and the second sheet-shaped rubber magnet layer 2. In the present invention, the thickness of the first sheet-shaped rubber magnet layer 1b is 0.8 to 2.8 mm, the thickness of the second sheet-shaped rubber magnet layer 2 is 3.0 to 5.0 mm, and the thickness of the adhesive layer 2a is 0.8 to 1.0 mm, thereby ensuring sufficient joining and adhesive strength due to magnetic force. Is this because

[0023] Fig. 8 is a cross-sectional view showing an example of the magnetized state of the first sheet-shaped rubber magnet layer 1a and the second sheet-shaped rubber magnet layer 2 according to the present invention. The arrows in the figure indicate the direction of the magnetic lines of force. In the case of a sheet-shaped magnet, as shown here, it is possible to strengthen the bonding by magnetic force by magnetizing it in a multi-pole manner, with the magnetic poles in the thickness direction alternating at regular intervals and by arranging the N pole and S pole opposite each other. In this case, it goes without saying that the magnetic force can be strengthened by orienting the magnetic powder dispersed in the rubber in the thickness direction to impart anisotropy rather than isotropy.

[0024] As described above, according to the present invention, it is possible to provide a signboard that can be attached to a curbstone, etc., and that has a replaceable sign surface. The present invention is not limited to the above-described embodiment, and it goes without saying that the present invention includes design changes that do not deviate from the gist of the present invention, including various modifications and corrections that can be conceived by a person having ordinary knowledge in the field of the present invention.
