DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member forming a reflector in a gaze guidance device such as a road sign.

[0002]

2. Description of the Related Art Conventionally, gaze guidance devices for road signs have been manufactured according to the purpose of use. FIG. 9 shows a gaze guidance device called a delinator. This gaze guidance device includes a reflector A and a housing B. Reflector A
Has a disk shape when viewed from the front, is made of a synthetic resin integrally formed with a retroreflective prism disposed on the back surface, and is incorporated in the housing B. This gaze guidance device is installed on a road by attaching the housing B to a pole C, or fixing the housing B to a guide rail, a guard cable, or the like. However, since the shape of the reflection plate A is a disk and is used only as a mark, it is generally installed at the roadside and at the end of the median strip. As another gaze guidance device, there is a gaze guidance device in which an arrow-shaped reflecting plate is fixed to a plate-shaped support member. This gaze guidance device is also installed by attaching a support member to a guide rail, a guard cable, or the like, but cannot be used for purposes other than indicating the traveling direction. It is used only for direction indication at the time of lane regulation.

[0003]

The road situation is becoming more and more complicated in recent years, and requires a sign according to the installation environment. However, the conventional line-of-sight guidance device designs a dedicated mold for molding a circular reflector if a circular road sign is required, and an arrow-shaped reflector if an arrow-shaped sign is required, and Because it is made by manufacturing, it requires considerable cost to prepare appropriate signs for various road conditions.

An object of the present invention is to make it possible to easily and inexpensively produce a gaze guidance device that can appropriately cope with increasingly complicated road conditions.

[0005]

In order to achieve the above object, the present invention provides a flexible band which can be bent into the form of characters, figures, etc., and a light beam from a vehicle arranged on one of the surfaces of the band. It is an object of the present invention to provide a reflector forming member of a gaze guidance device, comprising: a reflector that reflects light; and shape-retaining means for maintaining the shape when the band is bent.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In a reflector forming member of the present invention, a reflector serving as a road sign is formed by winding a strip in a spiral shape, such as a character or a figure, so that the reflecting surface of the reflector faces in the same direction. It is formed by bending in the shape of.

The flexibility of the band can be obtained by selecting the material constituting the band, but may also be obtained by making a cut at one or both of the longitudinal side edges of the band at intervals. .

The shape-retaining device is provided with a projection and a dent on a surface other than the reflection surface of the band, and is fitted with the projection or the dent on the surface of the band other than the reflection surface. The other member is provided on the member, and these members are fitted to each other. For example, when the reflector is formed by spirally winding the belt, one of the projection and the recess faces a surface intersecting the surface of the belt where the reflector is arranged, and the other faces the intersection surface. The shape can be retained by rolling while arranging on the surface and fitting these projections and depressions. When a reflector is formed by bending it into the shape of a character or figure, one of the projections or depressions is placed on the surface of the band facing the surface on which the reflector is arranged, and the other is a member independent of the band. The above-mentioned characters and figures are formed and arranged, and these projections and dents are fitted to each other to perform shape preservation.
These projections and depressions may be formed of a single member extending along the longitudinal direction of the band, or may be formed of a plurality of members arranged at intervals.

The reflector may be formed on the belt by laminating a reflective sheet having a retroreflective prism or the like on the belt, or may be formed on the belt by extrusion molding together with the belt. Good. Furthermore, the surface of the band where the reflector is arranged is formed in a waveform, and even if the reflector is arranged along this wave, the luminous body is embedded in the band with the light emitting surface positioned on the reflector surface. May be.

FIGS. 1 to 3 show an embodiment of a reflection plate forming member of the visual line guidance device of the present invention. As shown in FIG. 1, the reflection plate forming member includes a belt 10 and a reflector 20.

And a narrow and elongated band or string formed so that W <H. A projection 15 is integrally formed on a wide side surface 11 of the band body 10, and a recess 16 is provided on a side surface 12 facing the side surface 11. The projection 15 has a rectangular cross section, and is disposed along the entire length of the side surface 11 along the longitudinal direction of the band 10. The recess 16 is formed of a groove having a rectangular cross section, and is disposed coaxially with the protrusion 15 along the longitudinal direction of the band 10 over the entire length of the side surface 12. The width B of the recess 16 is
5 is formed to be slightly smaller than the width A, so that when the projection 15 is fitted into the groove 16 as described later, a tightening margin can be obtained. The strip itself is made of a flexible material, such as a soft synthetic resin, whose shape can be freely changed. For example, it is composed of a polyurethane resin-based thermoplastic elastomer having the following physical properties.

Hardness (JIS A) 89 Tensile strength (kg / cm ² ) 390 100% modulus (kg / cm ² ) 80 Elongation (%) 600 Tear strength (kg / cm) 120 It has the same width and length as the narrow side surface 13 of the body 10, and the side surface 1 covers the side surface 13.
3 above. The reflector itself is made of, for example, a retroreflective sheet, and is integrated with the band 10 by extrusion molding with the band 10 or by lamination molding on the band 10.

The reflecting plate forming member is wound in a spiral shape to obtain a reflecting plate of a circular line-of-sight guidance device as shown in FIG. 2, for example. That is, the reflection plate forming member is
It is made by winding around one end while fitting the projection 15 to the other end. At this time, by selecting the number of windings, not only is it possible to obtain a circular reflector for a delineator having an arbitrary diameter, but also because the grooves 16 and the projections 15 regulate the width of the disk in the thickness direction, Even if a large reflector is manufactured, no irregularities are formed on the circular end face where the reflector 20 is located, and a beautiful reflection surface having a uniform surface of the reflector 20 can be obtained. The width B of the groove 16 is equal to that of the protrusion 1 as described above.
5 is slightly smaller than the width A, the groove 16 holds the projection 15 when the reflector forming member is wound, and the projection 15
It can be easily wound without getting out of the way. As shown in FIG. 3, the reflecting plate forming member wound in this manner is fitted and fixed to a housing 30 having a hollow cylindrical shape with one end opened, and the housing 30 is attached to a pole or the like. A guidance device can be configured.

FIG. 4 shows another embodiment of the reflection plate forming member of the visual line guidance device of the present invention. The reflector forming member includes a belt 110 and a reflector 120.

The band 110 has a rectangular cross section, and the width W of the side surfaces 111 and 112 is perpendicular to the side surfaces 113 and 1.
It is formed in the form of a narrow and long strip formed so that W <H with respect to the width H of 14. The strip itself is made of a polyurethane resin-based thermoplastic elastomer having the above-described physical properties. Narrow side 1 of band 110
14 has a number of depressions 116. These recesses 116 are formed of blind holes, and are arranged at equal intervals along the longitudinal direction of the band 110. The reflector 120 has a width and a length corresponding to the side surface 113, and the side surface 1
