Description

{A Road Stud}

A road marker has a body having a generally hexahedral shape, and a reflector capable of reflex reflection is attached to a side of the body to reflect light incident from a headlight of the vehicle.

In addition, a connecting rod extends downward from the lower side of the body, and the connecting rod fixes the body to the center line of the road. In order to fix the body to the center line of the road, an adhesive such as epoxy resin is generally applied .

In general, the reflector is fixed to the reflector causing the reflex reflection, so it is not easy to change to the environment necessary for installation. Therefore, when the vehicle enters the steep curve road, the reflection efficiency for reflecting the light incident on the reflector is inevitably lowered. In order to solve this problem,

A first body having a reflector attached to an upper surface thereof and having a cross section including at least one obtuse angle; A rotation axis located at a vertex serving as a reference of the obtuse angle; A second body rotatably coupled to the rotary shaft and point-symmetric with respect to the first body with respect to a center of the rotary shaft; And an angle adjusting means that is fitted in a space opposite to a portion where the first body and the second body are in contact with each other when the first body and the second body are engaged with each other.

However, since the provided main body is a structure in which the first main body and the second main body are coupled to each other, the coupling force is weakened when the large load or impact is continuously received from the vehicle. In addition, foreign matter such as sand may get caught between the joints, or water penetration may weaken the durability in winter.

Therefore, the present invention is intended to solve the above-described problems and to direct the angle of the reflector of the marker to the front of the driver by adjusting it to the situation of the field such as a sharp curve.

Even if the straight line length is not a sharp curve length, the marker is installed in a lane around or around the road on which the vehicle is traveling, so it is observed that the vehicle headlamp or the driver's viewpoint is actually located on the left or right side will be. In this case, the same goes for the driver of the vehicle traveling on the opposite road. Therefore, it is necessary to adjust the reflection angle by a method different from the above-mentioned sharp curve road, and a rotation angle for adjusting the reflection angle of the method for solving the reflection angle is needed.

In order to solve such a problem,

main body; A fixture for fixing the main body to the road; And a reflector provided on the main body,

On both sides of the front and rear sides of the main body, a reflector mounting portion is formed to fix the reflector.

The reflector mounting portion includes a top wall; Bottom wall; Left and right side walls; Rear barrier; And a protruding portion, wherein the reflector mounting portion is provided with a rotation axis capable of switching the rotation angle of the reflector.

The configuration of the rotary shaft can be achieved through pivotal engagement. Alternatively, the rear surface of the reflector can be achieved by leaning against the protruding portion as a rotation axis, and the left and right end portions (or the upper and lower ends) of the reflector can be provided with a frictional force And thus, it is fixed. At this time, the shape of the reflector mounting portion is formed to match the arc of the reflector.

In order to maximize the frictional force or the like, it is possible to form the engaging concavity and convexity on the side wall of the reflector mounting portion (or the upper and lower walls), and the friction member may be provided on each end portion of the reflector.

It is possible to adjust and adapt the reflector which causes the retroreflective reflection of the road sign marker to various kinds of environments so as to be adaptable to various kinds of environments so that it can be always used for the headlight of the vehicle or the driver It is possible to cause reflection toward the front surface, thereby improving the reflection efficiency.

Accordingly, it is possible to direct the reflector to the driver in front of the vehicle even in the case of the headlight of the vehicle entering the steep curve road, and even in the case of the straight length, the marker can face the headlight of the vehicle in front, It is necessary to fine-tune it.

In other words, it is possible to adapt to a vehicle entering angle of a certain road such as a straight road and a curve road, thereby maximizing the efficiency of the recursive reflection.

The body 10, the fixing body 30, and the reflector 20 as shown in Figs. 3 and 4. This can be done according to the configuration and format of the usual marker.

As shown in the drawing, the main body 10 is generally provided with a rectangular shape in a plane, but various shapes such as a circle, an ellipse, and a polygon are used in addition to the above.

A rod-shaped fixing body 30 having a sharp end can be inserted so that the main body 10 can be firmly fixed to the road. In order to fit the fixing body 30, So that the hollow fixing holes 11 can be formed. The constructor performs a construction or installation process of digging a hole on the road and aligning the hole on the road with the fixing hole 11 and fixing the fixing body 30 therebetween.

In addition, there is also a construction in which the bottom of the marker bottle body 10 can be directly attached to the road by using an adhesive agent. In this case, the fixing hole 11 can be omitted without forming it. That is, the fixing agent 30 replaces the adhesive. Various methods of fixing the main body 10 of the marker bottle on the road have already been used at the construction site. In the present invention, the fixing hole 11 and the rod-like fixing body 30 are merely examples .

At both sides of the front and rear sides of the main body 10, a reflector mounting portion 12 having grooves formed therein to accommodate the reflectors 20 is formed.

The present invention is characterized by the reflector (20) and a space for accommodating the reflector (20). Therefore, we will concentrate on this point.

The reflector 20 includes a reflection sheet 21 and a reflection sheet attachment plate 22. The reflector 20 may have other shapes such as a circular shape, an elliptical shape, a polygonal shape, as well as a rectangular shape as shown in the drawing.

3, the reflection sheet 21 and the reflection sheet attachment plate 22 are prepared separately, and then an adhesive is applied to the back surface of the reflection sheet 21 and adhered to the front surface of the reflection sheet attachment plate 22, The reflection sheet 21 and the reflection sheet attachment plate 22 can be integrally formed and provided.

The reflective paper 21 generally uses a reflex reflection paper having a configuration for causing a retroreflective reflection. A reflective paper having a reflective material on the front side and an adhesive on the back side is used as the reflective paper. The retroreflective sheet has a characteristic feature that the headlamp of the vehicle is retroreflected in the direction again so that the nighttime driver is perceived as high brightness.

The reflective sheet attaching plate 22 to which the reflective sheet 21 is attached is provided with a rigid member such as metal or synthetic resin so that the shape of the reflective sheet 21 is supported so as not to be distorted,

Even if the edges of the reflector attachment plate 22 are in contact with the inner wall of the reflector mounting portion 12 at the time of installation and construction, it is also possible to select a member of the reflector 20 that is somewhat soft or elastic.

The reflector 20 is horizontally rotated so that the reflector 20 can be installed toward the front of the entering vehicle by changing the angle at which the reflector 20 is viewed from the left and right, It is possible to have a vertical axis of rotation possible. The reflector 20 may also be rotationally coupled with a rotation axis corresponding to the rotation axis. The reflector 20 is pivotally coupled to the reflector mount 12 through such a configuration. FIG. 4 shows the reflector 20 pivoted. Preferably, the pivot (pv) engagement has a friction against rotation so that the adjusted rotational angles? 1,? 2 can be maintained.

In addition, the reflector 20 should be formed with a space necessary for rotating the reflector 20 to change the angle. The space is necessary both to the front side and back side of the reflector 20.

2 to 5A, the reflector mount 12 includes the upper wall 12c, the lower wall 12b, and the left and right side walls 12a, Surrounds to protect from external environment.

Next, a rear wall 12d is disposed in the rear direction of the reflector 20, and the rear wall 12d takes the form of a gull shape, that is, a V-shape in plan view. When adjusting the rotation angles? 1 and? 2 in the viewing direction by rotating the reflector 20 in this manner, it is possible to secure left and right spaces for accommodating the rotation of the reflector 20 on the rear wall 12d side . The rotation axis of the reflector 20 is located in the V-shaped protrusion 12e.

3 and 4 illustrate a structure in which the lower end of the reflector 20 and the lower wall 12b of the reflector mount 12 are pivotally connected to each other, A structure may be adopted in which the upper end of the reflector 20 and the upper wall 12c of the reflector mount 12 are pivotally connected to each other.

However, the pivot (pv) coupling may be omitted for ease of fabrication and cost reduction. In this case, it is possible to adjust the rotation angles? 1 and? 2 with the rear surface of the reflector 20 leaning on the V-shaped protruding portion 12e and using it as a rotation axis. The means for maintaining the adjusted rotation angles? 1 and? 2 of the reflector 20 is not limited to that of the side wall 12a of the reflector mount 12 and that of the reflector 20, The frictional force or the engagement between the left and right end portions. Of course, a frictional force between the upper wall 12c or the lower wall 12b of the reflector mount 12 and the upper and lower ends of the reflector 20 may be used. C and 12b and the side wall 12a of the reflector mounting portion 12 in order to maintain the rotation angles? 1 and? 2 by frictional force or the like without separately pivoting Should be formed so as to correspond to the arc where the edge of the reflector 20 (i.e., each end) is rotated.

Here, it is the configuration of Figs. 5B and 5C to maximize the frictional force or the engagement to induce the fixing of the rotation angles [theta] 1, [theta] 2.

In the example of FIG. 5B, the engaging protrusions 12a 'are formed by taking the form of concavities and convexes formed on the left and right side walls 12a of the reflector mounting portion 12 with a floor and a valley. The left and right ends of the reflector 20 are caught by the engaging concave and convex portions 12a 'so that the rotational angles? 1 and? 2 designated at the time of construction can be maintained without being affected by a strong impact of the vehicle tire. You can win.

5C shows a state in which a frictional member having strong frictional force made of urethane or rubber is attached to the right and left ends of the reflector 20 to induce friction at a portion contacting the left and right side walls 12a of the reflector mounting portion 12, In a state in which it is stopped. Of course, the configurations of FIGS. 5B and 5C can be implemented together.

6 to 9 show examples of use of the present invention.

6 and Fig. 7 show the case of being used in a curved curve roadway w1. The rotational angle [theta] 1 is adjusted such that one end of the two reflectors 20 attached to the front and back of the tag body 10 as shown in Fig. In this way, the front surfaces of the reflectors 20 can be viewed from the front of the vehicles (v1, v2) headlights entering the opposite lane on the curve road as shown in Fig. 7B, respectively.

Relative examples are shown in Figs. 8 and 9. Fig. The two reflectors 20 attached to the front and back of the indicator bottle are arranged parallel to each other so as to maintain the best reflection angle with respect to the vehicles v1 and v2 entering on the straight road w1, ). In this way, the reflector 20 can always be directed to the headlamp of each vehicle entering from the opposite direction on the straight road.

9A, when the reflector 20 is given a rotation angle? To the left or right rather than to the front, if one side is viewed, the reflector 20 for inserting the reflector A space vac of one side of the mounting portion 12 becomes much vacant. That is, as the other space is narrowed between the rear surface of the reflector 20 and the walls of the reflector mounting portion 12, one vacant space vac is widened. However, foreign matter may penetrate here, or moisture may cause problems due to freezing and thawing in winter. Therefore, a member for covering the empty space vac is required.

In the example shown in Figures 10A and 10B,

Viscous oil, silicone. A fixed fluid 23c to be selected by members such as asphalt, a semi-solid state fluid such as a semi-liquid synthetic resin, or a particle-like solid such as a solid but movable sand; A fixed fluid passage (23b) having a narrow space in the center so that the fixed fluid (23c) passes through a large external force or an artificial operation but gives a large resistance so as to be difficult to cross again; A flexible synthetic resin capable of reducing the size due to plasticity by sealing the fixing fluid 23c to the left and right sides of the fixing fluid 23c, and a member made of a waterproof cloth or the like, As a bag 23a; And a space filling unit (23).

Thereafter, the rear surface of the reflector 20 is attached to the front surface of the space filling unit 23 as shown in FIGS. 10A and 11A. The reflector 20 incorporating the space filling unit 23 replaces the configuration in which only the reflector 20 is inserted into the reflector mounting portion 12 of the example shown in FIGS.

FIG. 11 shows the operation and the state of the space filling unit 23, and the state of FIG. 11A does not pressurize either the left or the right specially so that the reflector faces the front.

Fig. 11B illustrates pushing the left fixing fluid bag 23a of the space filling unit 23 to move the fixing fluid 23c to the right (fl).

On the contrary, FIG. 11C illustrates pushing the right fixing fluid bag 23a of the space filling unit 23 to move the fixing fluid 23c to the left (fl).

The pushing may be performed in advance from the outside before inserting the reflector 20 provided with the space filling unit 23 into the reflector mount 12.

Conversely, depending on the situation, it may be done immediately at the installation site after the insertion. In this case, the constructor is pushed by hand or using a tool to push it, which is clogged in the rear wall 12d, which is disposed in the backward direction of the reflector 20 of FIGS. 2-9, 11B and 11C, so that the fixing fluid in the space passes through the fixed fluid passage 23b and flows into the other fixed fluid pouch 23a. As a result, the pouch 23a is pushed in the opposite direction, (Fl).
