The angle setting mechanism for a floodlight disclosed in Patent Document 1 uses a telescope, which is a setting body that is detachably attached to the floodlight, to be arranged along the optical axis.Even when the light is off, the telescope finds the aiming point and sets the angle of the floodlight. It is possible. However, the angle setting mechanism as disclosed in Patent Document 1 has a problem in that the longitudinal direction of the light cannot be set when applied to a lighting unit that efficiently illuminates a relatively narrow and long area as shown in Patent Document 2. There was a point.

The present invention provides an adjustment device that can effectively specify the light irradiation direction of a road marking device that irradiates light so that a line-shaped light marking is drawn on the irradiated surface, and adjust the angle at which the road marking device is directed. It provides:

In order to achieve the above object, the present invention has the following configuration.
That is, the adjustment device according to the present invention is an adjustment device for grasping the light irradiation direction of a road marking device that irradiates light so that a line-shaped light marking is drawn on the irradiated surface, and each of the adjustment devices is formed separately. the monoculars are arranged in different directions, and the angle formed by the viewing direction of each of the monoculars is set to a magnitude of 20° or more and 160° or less. That is.

According to the adjustment device according to the present invention, two monoculars are provided and each of the monoculars is arranged in a different direction, so that the viewing direction of each monocular is different from that of the light that draws a line-shaped light mark on the irradiated surface. By attaching the adjustment tool to the road marking device so as to match the irradiation direction, the position where the linear light marking is drawn can be easily specified, and the irradiation direction of the light from the road marking device can be efficiently adjusted.
Further, since the angle formed by the viewing direction of each of the monoculars is set to a size of 20 degrees or more, the position of the linear light indicator drawn on the irradiated surface can be specified with high accuracy.
Furthermore, since the angle formed by the viewing direction of each of the monoculars is set to 160° or less, even when the light of the road marking device is irradiated at an angle in the longitudinal direction of the road, it is possible to obtain information by looking through the monocular. A situation in which the road, which is the irradiated surface, is out of the field of view is unlikely to occur, and the position of the linear light indicator drawn on the irradiated surface can be efficiently specified.

Furthermore, if the angle formed by the viewing direction of each of the monoculars is set to a size corresponding to the effective irradiation angle of the light of the road marking device, the longitudinal position of the line-shaped light marking can be easily identified with each monocular. Therefore, the direction of light irradiation from the road marking device can be efficiently adjusted.

Further, if the angle formed by the viewing direction of each of the monoculars is set to a size within the range of +0° and -15° of the effective irradiation angle of the light of the road marking device, each monocular can be visually recognized and identified. Since each position is within the effective irradiation range of the light of the road marking device, the road marking device, which is set using an adjustment device, should be illuminated to draw a line-shaped light marking from the irradiation range that can be seen through a monocular. It is possible to prevent situations where the camera is out of sight.

Furthermore, if a video output means is provided that outputs the video in the eyepiece of each monocular to an external monitor, even if the road marking device is installed in a place where it is difficult to see the monocular of the adjustment device directly, the video can be output to the external monitor. You can easily adjust the direction of light irradiation from the road marking device by checking the output image.

According to the adjustment device of the present invention, it is possible to effectively identify the light irradiation direction of the road marking device that irradiates light so that a line-shaped light marking is drawn on the irradiated surface.

First, the road marking device 5 shown in FIGS. 1 to 3 will be explained.
The road marking device 5 includes a main body portion 50 that radiates light emitted from a light emitter housed inside from a floodlight window 51 forward, and a main body portion 50 for installing the main body portion 50 on road incidental facilities such as erected pillars and walls. The support part 6 is provided.

The main body part 50 is formed into a rectangular box-like outer shape, and the light projection window 51 provided on the front surface thereof is formed into a substantially square shape. The radiation L emitted forward from the light projection window 51 is emitted from the entire light projection window 51 and is emitted so as to draw an elongated line-shaped light indicator S on the irradiated surface. Specifically, the radiation light L is provided so as to be emitted so as to spread in the left-right direction in FIG. 1, and not to spread in the vertical direction in FIG. It is provided. The radiation light L emitted in this manner can draw an elongated substantially rectangular line-shaped light indicator S whose longitudinal direction is in the left-right direction on the irradiated surface.

The support section 6 includes a mounting section 9 that is attached to a road auxiliary facility such as a support, and connecting fittings 7 and 8 that connect the mounting section 9 and the main body section 50.
The mounting portion 9 is an elongated body whose longitudinal direction is the left-right direction in FIG. 1, and has the same cross-sectional shape over its entire length. The mounting portion 9 is provided with a bolt groove 91 in the form of a blind groove that opens downward, and the bolt head is accommodated in this bolt groove 91 and the male threaded portion protrudes downward and outward. It is designed to be attached and fixed to road facilities such as roads.

The connecting fitting 7 is a metal fitting having a substantially U-shaped cross section, and includes a rectangular flat plate-shaped substrate portion 71 and flat plate-shaped connecting portions 72 extending downward from both edges of the substrate portion 71. It is formed by bending. The connecting fitting 7 is attached to the main body part 50 by bringing the upper surface of the base plate part 71 into contact with the lower surface of the main body part 50. The main body part 50 includes a male threaded part 52 projecting downward from the lower surface, and the connecting fitting 7 is attached by passing this male threaded part 52 through the base plate part 71 and screwing a nut thereon. In addition, by loosening the nut screwed onto the male threaded part 52, the connecting fitting 7 can be rotated using the male threaded part 52 as the rotation axis, and when the road marking device 5 is installed in road ancillary equipment. In this case, the direction of the main body portion 50 can be adjusted by rotating the connecting fitting 7, and the road marking device 5 can be installed so that the linear light marking S is drawn at a suitable position.

The connecting fitting 8 is a metal fitting having a substantially U-shaped cross section, and includes a rectangular flat plate-shaped substrate portion 81 and flat plate-shaped connecting portions 82 extending upward from both edges of the substrate portion 81. It is formed by bending. The connecting fitting 8 is attached to the attachment part 9 by bringing the lower surface of the base plate part 81 into contact with the attachment part 9. A bolt B1 whose male threaded portion projects upward is attached to the mounting portion 9, and the male threaded portion of this bolt B1 is passed through the base plate portion 81, and the connecting fitting 8 is attached by screwing a nut thereon.

The connecting fitting 7 and the connecting fitting 8 are connected by connecting parts 72 and 82, and a nut is screwed onto the male threaded portion of a bolt B2 passing through the connecting parts 72 and 82.
The connecting fitting 7 is provided so that it can be rotated with respect to the connecting fitting 8 using the bolt B2 as a rotation axis by loosening each nut screwed onto each of the bolts B2. By providing the connecting fitting 7 in such a manner that it can be adjusted by rotating the connecting fitting 7 to change the angle with respect to the connecting fitting 8, the orientation of the main body 50 can be adjusted and the line can be adjusted when the road marking device 5 is installed in road ancillary equipment. The road marking device 5 can be installed so that the optical marking S of the shape is drawn at a suitable position.

Similar to the connecting fitting 7, the connecting fitting 8 can be rotated with respect to the mounting part 9 by loosening the nut of the bolt B1 that attaches the base plate part 81 to the mounting part 9, using the male threaded part of the bolt B1 as the rotation axis. It is set up so that you can do it. With this arrangement, the direction of the main body 50 can be adjusted by rotating the connecting fitting 8 in the same way as the connecting fitting 7, and the road marking can be adjusted so that the line-shaped light marking S is drawn at a suitable position. A device 5 can be installed.

FIG. 4 is a schematic diagram showing an example of a situation in which the road marking device 5 of FIG. 1 forms a line-shaped light marking.
FIG. 4 depicts a road R on which a vehicle travels in the direction of the arrow from the right side to the left side in the figure from above, and shows the light emitted from the light projection window 51 of the road marking device 5 installed on the outside of the road R. A situation is shown in which a line-shaped light marking S is drawn so as to coincide with the position of a roadway outer line r1 formed on the road surface by irradiating light L onto the road surface.
The radiation light L emitted from the light projection window 51 of the main body part 50 is emitted so as to spread in the left-right direction in FIG. 4, and is emitted substantially parallel to the radiation direction without spreading in the direction perpendicular to the left-right direction. ing. By emitting the synchrotron radiation L in this way, a line-shaped light marking S is drawn on the road surface that is the irradiated surface, but the road marking device 5 is capable of drawing this line-shaped light marking S suitably. The effective irradiation angle E of light is set as the possible range. Specifically, the road marking device 5 emits the synchrotron radiation L so as to spread in the direction in which the effective irradiation angle E of the light is set, and spreads the synchrotron radiation L in the longitudinal direction in the direction in which the effective irradiation angle E is set. It is provided so as to form a line-shaped optical indicator S toward the target. In the road marking device 5 shown in FIG. 4, the effective irradiation angle E of light is set to 80°.
In addition, in FIG. 4, the longitudinal end of the linear light sign S drawn by the synchrotron radiation L is shown to coincide with the position of the end le of the range of the effective irradiation angle E of light, but The present invention is not limited to this, and the linear light indicator S may be provided such that the longitudinal end of the light indicator S is located outside the end le of the effective irradiation angle E of light. That is, the effective irradiation angle E of light is not defined by the line-shaped light mark S actually formed on the irradiated surface, but by the radiation light that can form a suitably visible line-shaped light mark S. This is a design value of the road marking device 5 that defines the angle of L, and is used as a reference when a road administrator who installs the road marking device 5 or the like considers the arrangement of the road marking device 5.

FIG. 10 is a front view showing a state in which the adjustment tool 1 of FIG. 7 is attached to the road marking device 5 of FIG. 1. In FIG. 10, illustration of the support part 6 of the road marking device 5 is omitted to simplify the drawing.
The adjusting device 1 of FIG. 10 brings the plate surfaces of the upper contact portion 21 and each side contact portion 24 of the mounting portion 2 into contact with the outer surface of the main body portion 50 of the road marking device 5, and also serves as the biasing means 27. When the snap lock is in the closed state, the front abutting part 22 and the rear abutting part 25 sandwich the front and rear of the main body part 50.

As shown in FIG. 10, when the mounting part 2 is attached to the road marking device 5, the monoculars 4 disposed on both the left and right sides of the light projection window 51 are located approximately at the vertical center of the light projection window 51. They are arranged as follows. Further, the angle formed by each monocular 4 directed in different left and right directions centering on the front-rear direction is set to 80°, which is the same size as the effective irradiation angle E of the emitted light L from the light projection window 51. ing. That is, in the state where it is attached to the road marking device 5, the position where the radiation light L of the road marking device 5 is irradiated can be visually recognized within the field of view obtained by looking through the eyepiece lens 41 of each monocular 4. There is. Specifically, in the field of view obtained by looking through the eyepiece lens 41, the end le of the effective irradiation angle E of the radiation light L that can suitably form the line-shaped light indicator S is located near the center of the field of view. . In other words, in the range of the linear light marking S drawn on the illuminated surface, each monocular 4 uses the eyepiece lens 41 to extend both ends of the longitudinal direction where the road marking device 5 can suitably draw the line-shaped light marking S on the irradiated surface. Each can be projected near the center of the field of view obtained by looking into it.

By arranging each monocular 4 in this manner, the position of the end le of the effective irradiation angle E of the radiation light L can be specified even when the road marking device 5 is in the off state. That is, by using the adjustment device 1, it is possible to specify not only the position in the width direction of the linear light sign S drawn on the illuminated surface such as the road surface, but also the positions of both ends in the longitudinal direction that can be formed suitably in terms of design. The installation angle of the road marking device 5 can be easily and accurately adjusted, such as by aligning the formation position of the linear optical marking S with the vehicle outer line r1. Furthermore, since the positions of both ends of the linear light markings S in the longitudinal direction can be identified by each monocular 4, a plurality of road marking devices are arranged at intervals so that a plurality of linear light markings S are drawn side by side in the longitudinal direction. 5, the longitudinal position of each line-shaped light marking S drawn on the road surface by each road marking device 5 can be appropriately arranged. As an example, as shown in FIG. 4, in a case where a plurality of linear light markings S are drawn on one roadway outside line r1, the width direction and the longitudinal direction of each linear light marking S formed are The position of each road marking device 5 can be grasped using the adjustment tool 1, and the installation angle of each road marking device 5 can be adjusted so that each road marking device 5 is drawn at an appropriate position.

Note that the adjustment instrument 1 according to the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the present invention.
For example, each monocular 4 of the adjusting device 1 is arranged at an angle corresponding to the effective irradiation angle E of the radiation light L of the road marking device 5 to which it is attached, but the present invention is not limited to this. If it is not necessary to specify the position in the longitudinal direction of the linear light indicator S to be drawn, the angle formed by each monocular 4 may be set to be different from the effective irradiation angle E. However, by arranging the angle formed by each monocular 4 at an angle corresponding to the effective irradiation angle E, as described above, not only the width direction position of the line-shaped light indicator S but also the design-wise formation The position of the longitudinal end can be identified. It is preferable that the angle formed by each monocular 4 is set to the same size as the effective irradiation angle E, but the angle formed by each monocular 4 is preferably set to be the same size as the above-mentioned effective irradiation angle E. It may be placed in Specifically, the angle formed by each monocular 4 is preferably set within the range of +0° and -15° of the effective irradiation angle E. By setting the angle to be less than or equal to the effective irradiation angle E, it is possible to reduce the situation in which the eyepiece lens 41 of each monocular 4 projects a position outside the range of the effective irradiation angle E, and the eyepiece lens 41 This makes it possible to more reliably display the formation position of the line-shaped optical marking S. Further, by setting the angle to be equal to or larger than -15° of the effective irradiation angle E, the eyepiece lens 41 of each monocular 4 can project a position that is largely shifted inward from the end of the range of the effective irradiation angle E. situations like this can be reduced.

In the case where the angle formed by each monocular 4 is set to be different from the effective irradiation angle E, it is preferable that the angle formed by each monocular 4 is set to a size of 20° or more and 160° or less. When the angle is set to less than 20 degrees, the accuracy of the position and orientation of the linear light indicator S specified by each monocular 4 decreases. Furthermore, if the angle is set to exceed 160°, there is a risk that a situation may occur in which the image in the eyepiece lens 41 of one or both monoculars 4 deviates from the illuminated surface that depicts the linear light indicator S. be.

Further, although the adjustment instrument 1 has each monocular 4 immovably fixed to each pedestal 3, the present invention is not limited to this, and each monocular 4 may be provided so that its orientation can be changed. By changing the direction of each monocular 4 and providing the angle formed by both members to be adjustable, the adjustment tool 1 can be suitably used. Further, by making the angle formed by each monocular 4 adjustable, the adjustment device 1 is suitably used in the installation work of the road marking device 5, which is provided so that the size of the effective irradiation angle E of light can be changed. be able to.
