The frame 100 includes a fixed frame 110, a support frame 120, and a hinge 130.

The sign frame body 201 is coupled to the stationary frame 110 and the upper ends of the stationary frame 110 and the support frame 120 are connected to each other by a hinge 130 so as to be relatively pivotable. Therefore, the sign 200 can be supported by the frame 100 in a standing state.

Fig. 4 is a cross-sectional view taken along the line A-A in Fig.

Referring to FIG. 4, the fixed frame 110 is engaged with the edge portion of the sign body 201. Here, the coupling between the fixed frame 110 and the sign body 201 may be detachably coupled using bolts, nuts, or the like, or may be permanently coupled through welding or the like.

The stationary frame 110 and the sign body 201 are coupled such that the stationary frame 110 protrudes more than one side of the sign body 201 as shown.

At this time, the stationary frame 110 is formed so that the height Hf protruding from one surface of the sign board body 201 is higher than the height Hm of the transit trail sign body 210 coupled to one surface of the sign board body 201 do.

The protrusions 111 and 121 and the depressions 121 and 122 are formed to have corresponding shapes as shown in the figure so that the frame 100 is folded about the hinge 130, So that the support frame 120 can be stably held on the support frame 110.

That is, even if a plurality of traffic safety markers 10 are loaded on the frame 100 as described above, the traffic lane marker body 210 may be damaged or its position may not be arbitrarily changed, The state in which the marking apparatus 10 is loaded can also be stably maintained.

In the meantime, the blocking symbol body 230 and the lane changing body (220 in Fig. 10) are also formed so that the height protruding from the sign body 201 is smaller than the height Hf at which the fixed frame 110 protrudes, And the like.

Fig. 5 is an enlarged view of a portion indicated by B in Fig.

5, a case 211, a light emitting means 213, a permanent magnet 214, a light diffusion sheet 215, a coloring sheet 217 and a cover 218 are included in the passing lane selection body 210 do.

The case 211 is formed so as to have an outline shape of the passage body of the passage shape with a side surface of a straight line, and one surface is opened to form an opening 212, and a space is formed therein.

The light emitting means 213 includes a support strap 213a and a light emitting element 213b.

Although not shown in detail, a plurality of light emitting devices 213b are arranged along the longitudinal direction on one side of the supporting strap 213a, and electric wires for supplying electric power to the light emitting device 213b are installed in the supporting strap 213a And an adhesive tape or the like may be laminated on the back surface.

The back surface of the support strap 213a may be adhered along the inner edge of the case 211 so that the plurality of light emitting devices 213b face the inside of the case 211. [ That is, the plurality of light emitting devices 213b may be installed along the inner edge of the case 211.

For reference, a high-luminance light emitting diode (LED) may be used as the light emitting means 213, and its color may be changed as needed. The structure in which the light emitting element 213 includes the light emitting element 213b and the support strap 213a is an example and the structure of the light emitting means 213 can be changed as necessary.

The permanent magnet 214 may be coupled to the case 211 as shown. The permanent magnet 214 is for separably coupling the guide body 210 to the one side of the guide body 201 (see FIG. 2). For this purpose, the guide body 201 may include a ferromagnetic body.

For example, the sign main body 201 may be formed by laminating super-high-intensity reflection paper described above on one surface of a plate-like steel sheet.

Here, the arrangement of the permanent magnets 214 assumes that the case 211 is made of a paramagnetic material such as aluminum in consideration of corrosion resistance and weight saving, and the gap between the permanent magnet 214 and the sign body 201 So that the permanent magnet 214 is disposed as close as possible to the rear surface of the crucible body 210 so as to be minimized.

Therefore, the passing lane charger 210 can be coupled to any position on one side of the sign board body 201 by the magnetic force of the permanent magnet 214, and the combined position can be easily changed have.

For reference, although not shown, if the adsorption rubber is attached to the outside of the case 211 in place of the permanent magnet 214, the guide body 201 can be separated from the surface of the sign body 201 by the adsorption rubber As shown in FIG.

The light-diffusing sheet 215 is arranged to cover the opening 212 of the case 211. The light diffusing sheet 215 diffuses light generated by the light emitting means 213 uniformly by diffusion reflection so that the light of the light emitting means 213 which is a point light source passes through the light diffusion sheet 215, Let it work together.

Accordingly, when electric power is supplied to the light emitting element 213b and light is generated in the light emitting element 213b, the light is dispersed while passing through the light diffusion sheet 215 to form the open portion 212 of the light diffusion sheet 215 It is possible to obtain an effect that light is generated from the entire covered portion.

The color changing sheet 217 is laminated on the opposite surface of the light diffusion sheet 215 on the opposite side to the opening 212 in the both surfaces. The color-changing sheet 217 will be described with reference to Fig.

Fig. 6 is a partially enlarged view for explaining the color-changing sheet of Fig. 5. 5 will be described together.

As shown in Fig. 6, the color changing sheet 217 includes a sheet body 217a, and the sheet body 217a has a plurality of through holes 217b.

At this time, if the surface of the seat body 217a has a specific color, when light is not generated by the light emitting means 213, one side of the passing body 210 appears as the color of the surface of the seat body 217a.

On the other hand, when the light emitting means 213 emits light, the light emitted through the light diffusion sheet 215 is radiated to the outside through the plurality of through holes 217b. Therefore, at the nighttime, The hue is seen as the color of the light generated by the light emitting means 213.

According to the management standard of the highway construction site of Korea Highway Corporation, the color of the lane symbol including the traffic lane symbol 210 is defined as black in the daytime and yellow light in the nighttime.

Therefore, when the light diffusion sheet 215 has a black surface and the yellow high-brightness LED is used as the light emitting element 213b, the traffic lane marker body 210 coupled to one surface of the sign board body 201 appears black during the day The yellow light emitted by the light emitting device 213b may be emitted through the through hole 217b at night so that one side of the sign board 201 may emit yellow light.

The light emitting element 213 and the coloring sheet 217 can be used both for daytime and nighttime use and the light diffusing sheet 215 can be used for both the light emitting element 213 and the coloring sheet 217, Since the entire surface is illuminated, the arrow shape can be clearly distinguished at a long distance, and the effect of improving the discrimination can be obtained.

The cover 218 is coupled to the case 211 such that the light diffusion sheet 215 and the color fading sheet 217 are fixed to the case 211. The cover 218 may be provided with an opening 219 having a shape corresponding to the opening 212 formed in the case 211 and a case 211 may be formed instead of the opening 219 It may also be made of a transparent material.

For reference, instead of coupling the cover 218 to the case 211, the light diffusion sheet 215 and the color fading sheet 217 may be directly coupled to the case 211 without the cover 218. [

Fig. 7 is an enlarged view of a portion indicated by C in Fig.

7, the case 231, the light emitting means 233, the permanent magnets 234 and 234a, the light diffusion sheets 235 and 235a, the color shift sheets 237 and 237a, A cover 238 is included.

2, the case 231 is formed so as to have an outline shape of the shielding body 230 of an arrow shape in which the intermediate portion is once bent as shown in Fig. 2, and both sides are opened to form openings 232, 232a And a space is formed therein.

The light emitting means 233 is provided on the inner edge of the case 231. Here, the light emitting means 233 includes a support strap 233a and a light emitting element 233b, which are the same as the above-described support strap 213a and the light emitting element 213b, respectively.

The permanent magnets 234 and 234a may be closely coupled to one surface and the rear surface of the case 231. [ This is so that the one-side or the rear face of the block plug body 230 can be detachably coupled to one face of the sign body 201 (see FIG. 2).

In other words, the shielding box body 230 may be coupled to one surface of the sign body 201 if necessary, or may be reversed so that the back surface is coupled to one surface of the sign body 201.

For example, assuming that the state shown in Fig. 3 is a state in which one side of the blocking element body 230 is coupled to one surface of the sign body 201, the blocking element body 230 shown in Fig. It can be said that it is coupled to one surface of the sign board body 201.

When both sides of the blocking box body 230 can be coupled to one side of the sign board body 201 as described above, the one side of the blocking box body 230 Or the rear surface of the main body 201 can be selected.

In other words, when the content to be displayed by the road blocker body 230 is 'left lane missing', the road blocker body 230 is attached to the sign body 201 in the right direction as shown in FIG. And when the 'right lane disappearance' is displayed, it is possible to arrange the road blocker body 230 in the shape of an arrow bent in the left direction as shown in FIG.

Therefore, if both sides of the blocking box body 230 can be respectively coupled to the one surface of the sign board body 201, it is not necessary to separately manufacture and maintain the blocking box body 230 in accordance with the direction, The number of traffic safety markers 10 to be provided on the spot or the like can be reduced.

However, as described above, in order to use both sides of the blocking box 230 for daytime and nighttime, the light must be able to be emitted to both sides of the blocking box 230 at night. Will be described next.

The light diffusion sheets 235 and 235a are arranged to cover the openings 232 and 232a formed in the case 231, respectively.

Accordingly, when power is supplied to the light emitting element 233b and light is generated in the light emitting element 233b, the light is dispersed while passing through the light diffusion sheets 235 and 235a to be dispersed in the openings of the light diffusion sheets 235 and 235a It is possible to obtain the same effect as that light is generated from the entire portion covering the light emitting portions 232 and 232a.

The color changing sheets 237 and 237a are stacked on opposite surfaces of the light diffusion sheets 235 and 235a facing the openings 232 and 232a, respectively. Here, since the color-changing sheets 237 and 237a are the same in structure and function as the color-changing sheet 217 described with reference to Fig. 6, duplicate descriptions are omitted.

When the light emitting means 233 emits light, the light blocking sheet 230 is lighted by the light diffusion sheets 235 and 235a disposed on both sides of the light blocking sheet 230, You can use both sides of Edo.

The cover 238 is coupled to the case 231 so that the light diffusion sheets 235 and 235a and the color fading sheets 237 and 237a are fixed to the case 231. [ Openings 239 and 239a corresponding to the openings 232 and 232a formed in the case 231 may be formed in the cover 238, respectively. Alternatively, although not shown, the openings 239 and 239a may be formed in the cover 238, but the cover 238 may be made of a transparent material.

The light diffusion sheets 235 and 235a and the color changing sheets 237 and 237a may be directly coupled to the case 231 without the cover 238. [

The arrangement of the permanent magnets 234 and 234a is based on the assumption that the case 231 is made of a paramagnetic material such as aluminum in consideration of corrosion resistance and weight saving and is provided with the permanent magnets 234 and 234a and the sign body 201 The permanent magnets 234 and 234a are arranged as close as possible to one side and the rear side of the block-symmetrical body 230, respectively, so that the interval between the permanent magnets 234 and 234a can be minimized.

If the case 231 is made of a ferromagnetic material such as steel capable of forming a magnetic circuit, the number and the arrangement of the permanent magnets 234 and 234a may be changed, an example of which is illustrated in FIG.

Fig. 8 shows a modification in which the arrangement of the permanent magnet in the blockage symmetry body 230 shown in Fig. 7 is changed.

8, the permanent magnet 334 is disposed inside the edge of the case 231 in the shielding box body 230 by a lane.

This is a case where the case 231 is made of a mandrel, as described above. That is, the case 231 made of a ferromagnetic material is magnetized by the permanent magnet 334 which is in contact with the inside of the case 231, so that the case 231 also has a magnetic force similarly to the permanent magnet 334.

At this time, when one side of the blockage symbol body 230 comes close to one surface of the sign body 201, a magnetic attractive force is applied between one side edge of the case 231 and the sign body 201, One side of the body 230 can be coupled to one side of the sign body 201.

On the other hand, when the back surface of the blocking box body 230 approaches the one surface of the sign body 201, a magnetic attractive force is applied between the other side edge of the case 231 and the sign body 201, The rear surface of the body 230 may also be coupled to one surface of the sign body 201. [

The permanent magnets 234 and 234a may be made of a neodymium magnet having a strong magnetic force so as to apply a magnetic force of a sufficient magnitude between the block plug body 230 and the sign body 201. [ Can be used.

FIG. 9 and FIG. 10 are front views illustrating the contents change of the traffic safety markers 10a and 10b according to an embodiment of the present invention.

9, a sign body 210, 210a, a pair of street sign body 230, 230a, a work area body 250, (Not shown).

Referring to Fig. 10, three lane changing bodies 220, 220a and 220b, a working area selecting body 250 and a distance indicating selecting body 260 are coupled to a sign board main body 201. Fig.

According to the arrangement of the components as shown in the figure, the traffic safety sign device 10b informs the driver who is driving on the road 'that the construction is proceeding from the left side of the one way three- It is to be done.

In this way, depending on the position where the traffic safety markers 10a and 10b are disposed, the work area marking body 250 and the distance marking bodies 260 and 270, in which characters and symbols suitable for the marking body 201 are disposed, And the number and direction of the road blocker 220 and the road blocker body 230 are adjusted and combined with the traffic lane 210, the lane changing body 220 and the lane blocking body 230 in accordance with the situation such as road blocking and detour, Various contents can be displayed.

That is, since the traffic safety marking apparatuses 10, 10a, 10b according to the embodiment of the present invention can express various contents by combining the symbols, the frame (100 in FIG. 2) 200) can be reduced. Accordingly, manpower and time required for storing, transporting, installing, and managing the traffic safety marking devices 10, 10a, 10b can be saved.
