Description

Technical Field

[0001] The present invention relates to a signboard installed on a curbstone, and more particularly to a signboard in which a sign portion made of a reflective material has a configuration detachable from an installation surface.

Background Art

[0002] Signboards include standing signboards and placed signboards, which are used to display information such as public announcements, construction guides, warnings, and advertising.

[0003] Such methods of standing signboards and placed signboards increase the occupied area of the road, and measures for ensuring public safety are also required. For example, adding weights to prevent scattering due to bad weather is an example. Also, when the reflective material is directly attached with an adhesive or painted, it is based on the idea of simply seeking visibility, and other methods have not been considered.

[0004] As one of the countermeasures for such a situation, Patent Document 1 discloses a method of directly attaching a reflective material to the upper part of a curbstone with an adhesive or the like to arouse danger to pedestrians and the like. Patent Document 1 also discloses a curb spike installed around a road to promote line-of-sight guidance for drivers and clarify road alignment, which is provided with a retroreflector and a transparent resin layer containing a phosphorescent pigment is provided on the outer surface of the retroreflector.

[0005] However, although the curb spike disclosed here can be easily attached to the curbstone with an adhesive, the cut-off portions of the curbstone have various shapes, making it difficult to attach with an adhesive, and the attachment location is limited to a flat surface such as the upper surface of the curbstone. Moreover, if even a part is damaged, the whole needs to be replaced, resulting in increased costs, which is an issue to be considered.

Summary of the Invention

Problems to be Solved by the Invention

[0007] In view of the above problems, an object of the present invention is to provide a signboard that has few restrictions on the attachment position to the curbstone and can easily replace only the parts that are frequently damaged.

[0008] In order to solve the above problems, the present inventor has intensively studied the structure of the signboard and the method of attaching it to the curbstone, and as a result, has made the present invention.

[0009] A signboard according to an aspect of the present invention for solving the above problems has a sign surface portion that indicates required information by a reflective material, and a first sheet-like rubber magnet layer is adhered to the surface opposite to the sign surface portion. In a signboard having a joining means for the sign material on at least one of the side surface and the upper surface including at least the cut-off portion of the curbstone, the joining means is provided on at least one of the side surface and the upper surface including at least the cut-off portion of the curbstone. A second sheet-like rubber magnet layer joined by an adhesive layer formed on the surface, a columnar portion having substantially the same height as the total height of the sign material, the first rubber magnet layer, and the second rubber magnet layer, and the columnar portion. It has a base portion that is integrally formed with the columnar portion, has an area larger than that of the columnar portion, and has a height substantially the same as the thickness of the adhesive layer, and a female screw provided on the columnar portion. The columnar portion is arranged in a through hole that communicates the sign material and the second sheet-like rubber magnet layer, the base portion is embedded in the adhesive layer, a male screw that screws into the female screw of the first joining means, and a second joining means having a through hole in a portion that is exposed without screwing into the female screw. It is characterized by having a locking pin having a substantially E-shaped configuration and a central protrusion penetrating the through hole.

[0010] In addition, the signage board according to one aspect of the present invention is characterized in that the thickness of the first sheet-shaped rubber magnet layer is 0.8 to 2.8 mm, the thickness of the second sheet-shaped rubber magnet layer is 3.0 to 5.0 mm, and the thickness of the adhesive layer is 0.8 to 1.0 mm.

[0011] In addition, the signage board according to one aspect of the present invention is characterized in that unevenness that engages with each other is formed on the opposing surfaces of the first sheet-shaped rubber magnet layer and the second sheet-shaped rubber magnet layer.

Effects of the Invention

[0012] The signage board according to the present invention can be arranged according to the shape of at least one of the side surface including at least the cut-down portion of the curb and the upper surface, and has means for detachably joining the signage surface for marking predetermined information on the signage board. Therefore, the signage surface can be easily replaced, and the occupied area of the signage board itself in the road space can be reduced. The fact that the signage surface is replaceable is also important in terms of being used in an environment such as a road curb that is easily damaged.

[0013] In addition, in the signage board according to the present invention, it is also possible to provide unevenness that engages with each other on the joining surface side of the sheet-shaped rubber magnet constituting the joining means, and it is possible to suppress the displacement between the joining surfaces by only men.

Mode for Carrying Out the Invention

[0015] Next, embodiments of the present invention will be described with reference to specific figures. FIG. 1 is a perspective view showing an example of a signboard according to the present invention attached to the slope of a curb, and FIG. 2 is a view showing details of an example of the cross-section of the sign material of the present invention.

[0016] As shown in these figures, the sign material 1 is composed of a sign face portion 1a and a first sheet-like rubber magnet layer 1b. The methods of the reflector used for the sign face portion 1a include retroreflection, diffuse reflection, specular reflection, etc., and a retroreflective reflector, which is frequently used for road signs, is desirable.

[0017] Also, for joining the sign material 1 to the surface of the curb 5, a second sheet-like rubber magnet layer 2, which is joined to the surface of the curb 5 by an adhesive layer 2a, is used. For the first sheet-like rubber magnet layer and the second sheet-like rubber magnet layer, a material in which magnet powder is dispersed in rubber is used, and as the material of the magnet, a ferrite-based one is desirable in terms of outdoor durability and cost.

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

[0019] The base portion 3b of the first joining means 3 is arranged to be embedded in the adhesive layer 2a as shown in Fig. 2, and the columnar portion 3a is arranged in a through hole that communicates the marking material 1, that is, the marking surface diagram 1a, the first sheet-shaped rubber magnet layer 1b, and the second sheet-shaped rubber magnet layer 2, and an internal female screw 3c is provided therein.

[0020] The second joining means 4 is provided with a male screw 4c that screws into the female screw 3c of the first joining means 3, and as shown in Fig. 2, the exposed portion 4a and the flange portion 4b are arranged in a state of protruding from the marking surface portion 1a. Here, an example where the flange portion 4b is exposed is shown, but the flange portion 4b may not be exposed.

[0021] Fig. 5 is a plan view showing an example of the E-shaped locking pin 6 according to the present invention. Fig. 6 is a perspective view showing a state where the E-shaped locking pin 6 is inserted into the through hole 4d of the second joining means 4. As shown here, since the horizontal plane area of the E-shaped pin 6 is larger than the horizontal plane area of the flange portion 4b of the second joining means 4, it is possible to prevent the marking material 1 from moving upward in the figure and coming off the surface of the curb 5.

[0022] Fig. 7 is a perspective view showing a state where convex portions 1c and concave portions 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, if it is before the vulcanization process, it is not difficult to impart such unevenness by a heating press using a mold, and the positional deviation between the first sheet-shaped rubber magnet layer 1b and the second sheet-shaped rubber magnet layer 2 can be suppressed by the engagement of the unevenness. In the present invention, by setting the thickness of the first sheet-shaped rubber magnet layer 1b to 0.8 to 2.8 mm, the thickness of the second sheet-shaped rubber magnet layer 2 to 3.0 to 5.0 mm, and the thickness of the adhesive layer 2a to 0.8 to 1.0 mm, a sufficient joining force and adhesive force due to magnetic force can be ensured. for which

[0023] FIG. 8 is a cross-sectional view showing an example of the magnetization state of a first sheet-shaped rubber magnet layer 1a and a second sheet-shaped rubber magnet layer 2 according to the present invention. The arrows in the figure indicate the direction of magnetic field lines. In the case of a sheet-shaped magnet, as shown here, a multi-pole magnetization in which the magnetic poles in the thickness direction are alternated at regular intervals, and by opposing the N pole and the S pole, the joining by magnetic force can be strengthened. Also in this case, it goes without saying that the magnetic force can be strengthened more than in the isotropic case by orienting the magnet powder dispersed in the rubber in the thickness direction to impart anisotropy.

[0024] As described above, according to the present invention, it is possible to provide a signboard that can be attached to a curbstone or the like and whose display surface can be exchanged. Note that the present invention is not limited to the above-described embodiment, and any design changes including various deformations and modifications that can be conceived by those having ordinary knowledge in the field of the present invention and that do not depart from the gist of the present invention are of course included in the present invention.
