Description

  The present invention relates to a line-of-sight guidance reflector (hereinafter referred to as a “reflector”) used by being attached to a curb, a pedestrian separation zone, a sidewalk block or the like.

When driving a car at night, there is a problem that it is difficult to understand the position of the curb or the like, or when the road is curved. Therefore, in order to reflect the light of the headlight and make the driver visually recognize the curb or the curve, a reflector is attached on or next to the curb.
A conventional reflector of this type and an example of its attachment are shown in FIGS. The example of FIG. 9 is the most basic shape, and the base board 100 has a square shape on the plane, a trapezoidal side surface, and reflective lenses 101 and 102 attached to the left and right inclined surfaces. It is attached to the curb 103 so as to be inclined slightly inward. By doing in this way, the reflective efficiency in the reflective lens 101 is raised and the gaze guidance effect is enhanced.

  Next, in the example of FIG. 10, the reflector 100 having the circular reflection surface 105 is attached to the reflector 100 so that the reflector 100 is attached at an angle as shown in FIG. 9. Even if it is not, it is an example of a shape that improves the reflection efficiency by the action of the circular reflection surface 105, and increases the effective visibility especially in a curve. In FIG. 10, reference numeral 106 denotes a reflection lens attached to the opposite side of the reflection lens 104, but this lens 106 may not be provided.

However, the reflector 100 shown in FIGS. 9 and 10 has the following drawbacks.
1. In the case of the reflector 100 of FIG. 9, when the inward slope is given to the curb stone 103 one by one, this slope varies, the reflection efficiency differs individually, and unevenness occurs in the reflected light. .
2. In the case of the reflector 100 in FIG. 10, the number of reflectors that are brought in often does not match the number of reflectors that are attached to the field curve due to work at the site. The next day's work. For this reason, it is necessary to always go to the site with a large number of numbers, which is bulky and time-consuming to arrange the numbers.

3. Since the reflector 100 in FIG. 10 is for a curve, it is necessary to prepare two types of reflectors shown in FIG. 9 for straight lines.
4). There are two types of automobiles: large cars and small cars. The height of the headlights does not change that much, but the height of the driver's seat is very different. This is evident when comparing the height of the driver's seat of a large truck and a sports car or light car. In contrast to this difference in height, the conventional reflectors use reflection lenses having the same reflection angle in the case of FIG. 9 and FIG.
5. As shown in FIG. 9 and FIG. 10, when reflection lenses are attached to the front and rear, there is a combination of lenses of the same color and lenses of different colors, but this color combination cannot be selected in the field.

  This invention is the invention of the reflector which solved the subject described in the said 1-5, Comprising: Reflection efficiency is high, and it can construct so that it may become all constant reflection efficiency, and it is one for a straight line and a curve. Furthermore, it is characterized in that the reflector structure is effective for both large and small vehicles.

  That is, according to the first aspect of the present invention, in the line-of-sight guide reflector, the line-of-sight guide reflector used by being attached to a curb, a walkway separation zone, a sidewalk block, a side wall, etc. The left and right reflector elements are divided into left and right reflector elements, and the left and right elements are connected to each other so as to be rotatable around the center of the joint. A V-shaped wedge fitting port is formed on one side of the rotating shaft from the end toward the rotating shaft side, and can be fitted to the wedge fitting port and can be wedged. It is characterized by comprising a wedge that can be fitted into a V-shaped opening formed by opening the joint of the left and right elements on the opposite side of the fitting port.

  Furthermore, in the invention described in claim 2, in the invention described in claim 1, the left and right elements are rotatably connected to each other on the rotating shaft, and are detachable at the rotating shaft. It is characterized by.

  Furthermore, in the invention described in claim 3, in the invention described in claim 1 or 2, a wedge fitting port and a fitting portion that is detachably fitted to each other are formed between the opening and the wedge. It is characterized by that.

  Further, in the invention according to claim 4, in the invention corresponding to any one of claims 1 to 3, the reflection lens attached to the left and right elements has a high and low reflection region. It is characterized by being.

According to the reflector according to the present invention employing the above configuration, the following effects can be obtained.
1. The reflector can be divided into left and right parts, and the angle of the elements of the left and right reflectors can be set freely. To improve visibility. Of course, depending on the application, it may be left as is. That is, the reflector of the present invention has a structure that can be used in two ways.
2. Since the angle of the reflector element can be easily fixed by attaching and detaching the wedge, the angle can be easily set in the field.
3. The left and right reflector elements can be separated at the rotating shaft, so they can be separated during storage and transportation and used while assembling on-site, as well as other elements with different colors and functions. Can do.
4). Since the right and left reflector elements can be assembled freely, it is sufficient to match the numbers on site, and the number does not match, so there will be no trouble in the work.
5. Since the reflecting lenses of the left and right reflector elements can be combined with different colors as well as the same color, the application is expanded.
6). By dividing the reflection angle of the reflection lens for large vehicles and small vehicles, visibility at both driving degrees is enhanced.

In the present invention, for example, a polycarbonate resin having excellent transparency can be used for the reflective lens. The reflecting lens may be colored yellow or red, or may be white, or may be used in combination with different colors. For the base of the reflector, for example, methacrylic resin, ABS resin, polycarbonate resin or the like can be used.
Of course, the reflection surface of the reflection lens may be the same reflection region, but may be set to an angle region for a large vehicle and an angle region for a small vehicle.

  Based on FIGS. 1-8, the Example of this invention described in Claims 1-4 is demonstrated in detail. FIG. 1 is a view of the entire finished reflector. However, pins and wedges are drawn separately as images. 2 is a plan view of the reflector, FIG. 3 is a back view, FIG. 4 is an enlarged sectional view taken along the line AA ′, FIG. 5 is an enlarged sectional view taken along the line BB ′, and FIG. 6 is a perspective view of the separated reflector element. FIG. 7 is an explanatory view showing a state in which the reflector element is opened and the reflection lens is angled, and FIG. 8 is an explanatory view showing a state in which the reflector according to the present invention is attached to the curb block.

In each of these drawings, reference numeral 1 denotes the entire reflector. The reflector 1 is divided into left and right at the center, and is composed of a left reflector element 2 and a right reflector element 3, which are symmetrical in shape. Reference numerals 4 and 5 denote reflection lenses attached to the two reflector elements 2 and 3.
Reference numeral 6 denotes a joint of the two reflector elements 2 and 3, and 7 denotes a rotary shaft that rotatably connects the two reflector elements 2 and 3 in the middle of the joint 6. 4, as shown in FIG. 4, a downward shaft tube 9 formed on the left reflector element 2 is fitted from above to an upward shaft tube 8 formed on the right reflector element 3 side. The pin 10 is inserted into the shaft cylinder 8 from above, and the protrusion 11 of the pin 10 is engaged with the engaging portion 12 formed in the lower part of the upward shaft cylinder 8 to prevent the pin 10 from coming off. . However, since the lower half of the pin 10 is bifurcated, it can be easily pulled out with a fingertip.

  Reference numerals 13 and 14 denote inclined portions which are cut in the opening direction at an angle of 30 ° toward the outside from the rotating shaft portion 7 at the seam 6. , And a wedge 16 having a 16 ° angle is fitted into the wedge fitting port 15 from below, whereby the wedge 16 fixes the left and right reflector elements 2 and 3 in parallel. As is apparent from FIGS. 1 and 5, the wedge 16 has fitting protrusions 17 and 18 formed on both side surfaces thereof. The fitting protrusions 17 and 18 are shown in FIGS. 3 and 5. As described above, the joint 6 of the reflector elements 2 and 3 can be fitted and fixed from below into the engagement holes 19 and 20 formed by opening the lower shaft of both joints with the rotary shaft portion 7 as a boundary. It is like that.

The angle of the wedge fitting port 15 is 16 ° in this embodiment, but this angle can be freely set.
In this embodiment, the reflecting lenses 4 and 5 are for large vehicles and small vehicles. In FIG. 4, the angle a is a reflecting surface for small vehicles, and the angle b is a reflecting surface for large vehicles. The angle is set. However, depending on the mounting location, reflection lenses 4 and 5 that do not give such an angle difference may be used.

Of course, the reflector 1 having the above-described configuration may be attached in the state shown in FIG. 1, but when attaching at an angle, in the state shown in FIG. Since the wedge fitting port 15 is opened by this removal, when the joint on the opposite side is opened to the left and right, the wedge fitting port is closed, and the open port 21 which is a 16 ° wedge fitting space on the opposite side is shown in FIG. As shown in Therefore, by inserting the wedge 16 into the opening 21 from below, the left and right reflector elements 2 and 3 are changed and fixed at an angle of 16 ° shown in FIG.
By attaching the reflector 1 on the curb 103 as shown in FIG. 8, the reflecting lens 5 faces the roadway as it is, and as a result, the reflection efficiency is increased. In FIG. 3, 22 and 23 are fitting holes into which the fitting protrusions 17 and 18 of the wedge 16 are fitted.
