Description

Road Marking Bottle {BOTTLE FOR THE ROAD SIGN}

The present invention relates to a road marker bottle, and more particularly, a road marker bottle installed on the ground or road surface to clearly indicate the lane during night driving, and to the thermal expansion of the fixed position of the road surface without providing a separate fixing means. It's about a road marker that's going around.

In general, all road signs, road marking bottles, and road marking bottles are designed to visually identify road surfaces, the ground, road centerlines, guide lines, and safety lines at night. It is used as a means of protecting them.

The road marking bottle integrally has a cast support for forming an installation hole in the bottom of the road and then driving and fixing it in the installation hole. Most of the road marker bottles are made of metal that can be cast.

The road marker bottle is fastened to the front and rear of the body to increase the nighttime identification, a body for displaying the center line of the road, a support protrusion for protruding at the bottom of the body and being embedded in the installation hole of the road, and supporting the body. It consists of a light-emitting body which emits light.

However, such a general road marker bottle is a metal material, when it is installed in a summer road where hot heat is felt or in a winter road where a relatively cold air is felt more, the metal support protrusion is pressed and fixed to the installation hole of the road. It is difficult to install stably by adapting to heat deformation.

In addition, since the metallic support protrusion is driven into the installation hole of the road with a pressure larger than that of almost concrete nailing, an excessive amount of stress is applied to the road marker bottle itself, which makes the construction work very difficult and difficult. There are disadvantages.

In addition, according to the characteristics of the metal road, the general road marker bottle is cracked after a long time of use, and often ruptures and breaks locally due to frequent temperature changes.

A road marker bottle for solving these problems is disclosed in Korean Patent Application No. 49767 in 2001.

This application technique is a vertical rod having a hollow portion formed by mixing 10-40 wt% luminous stone powder in a weight ratio (hereinafter referred to as 'wt%') with a synthetic urethane, and 0.2-thickness on the left and right outer peripheral surfaces of the vertical rod. A groove is formed to a depth of 0.3 times and a reflecting mirror is attached to the groove with an adhesive or the like.

In addition, the conventional road marker bottle is formed by mixing 10-40 wt% luminous stone powder emitting luminescent light to urethane, in addition to the vertical rod, as shown in FIG. 2), the reflector 3 is attached.

The conventional road marker bottle itself emits a soft luminous light at night, so that the driver can easily identify from a distance at night, protects the driver's vision of a high-speed vehicle, and more accurately identifies the lane. There are features that can be done.

However, the conventional road marker bottle is a general method of construction of the road marker bottle due to the nature of the material, when it is installed on the road, it is difficult to be installed in the airtight hole according to the elastic deformation, and the reflector is simply attached to the grooves on the left and right sides. The above-mentioned general road markers do not solve all of the problems pointed out.

In particular, since the conventional road marker bottle has a reflector only on the left and right sides as in a general road marker bottle, the role of the reflector is limited to correspond to the installation position of the reflector, and in particular, the reflector surface and the rim surface of the groove coincide with each other. Since the reflector is easily broken and lost by external force.

In addition, the conventional road marker bottle has a disadvantage that the reflector is easily separated and separated by heat deformation.

In addition, the conventional road marker bottles have the same circumferential diameter in the axial direction as in general road marker bottles, and thus have a disadvantage of being difficult to be secured to the installation holes of roads having foreign matters and stones and irregular inner surfaces generated during drilling. .

In addition, the conventional road marker bottle has only a metallic color or a single color in accordance with a formal road, there is a disadvantage that does not fit well in places such as bicycle roads, pedestrian roads, safety zones and the like.

In addition, the conventional road marker bottle or the metallic road marker bottle has an angled upper horizontal surface, which causes tire wear of the vehicle and at the same time, the amount of impact applied by the tire of the vehicle is concentrated at the angled corners, thereby causing local breakdown and damage. It is the cause.

Therefore, according to the present invention for achieving the above object, in forming the body portion and the insert portion of the polyurethane material having a relatively high hardness integrally, the construction is easy according to the material and shape structure of the insert portion, road surface It provides an excellent installation and fixing ability to cope with thermal expansion of the fixed position, and has a relatively small breakage and damage, and provides a road marking bottle with various colors.

The road marking bottle of all the embodiments described below is basically a high hardness polyurethane material or a synthetic resin material having a corresponding hardness. For example, in the embodiments provided in the present invention, a pellet or flake thermoplastic polyurethane (TPU: Thermoplastic PolyUrethane) was used, which is extruded, injection molded, calendered, blow molded ( blowing) or the like to form the road marking bottle of the present invention.

In particular, polyurethane requires a material having a hardness (strength) of about 90 to 95 as the A hardness meter (Shore A). For example, B90A 11S, B95A 11S, 'HI- STOMER (hardness 93 size), etc. can be used.

Such polyurethanes have plastic properties (strength) and rubber properties (elastic) at the same time, so-called 'TPU polyurethane elastomer'.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, and the same or similar reference numerals will be given to the same or similar components in each embodiment.

First Embodiment

2 is a perspective view of the road marker bottle installed on the road surface according to the first embodiment of the present invention, Figure 3 is a cross-sectional view of the road marker bottle cut along the line A-A 'shown in FIG. 4 is a bottom view of the road marker bottle shown in FIG. 2.

As shown in FIG. 2, the road marker bottle has a semi-spherical and semi-elliptic sphere shape, and has a circular groove 101 for mounting the reflective tape 110 on the circumferential direction in the circumferential direction, and a skirt portion 102 at the bottom thereof. ) Is formed of a main body portion 100 and the insertion portion 190 protruding integrally from the bottom of the shaft center of the main body portion 100.

The inserting portion 190 is a kind of support protrusion, and is press-fitted into the installation hole of the road formed at the fixed position of the ground or the road surface 4, and has a coupling structure fixed to the installation hole of the road by its own elastic force.

Hereinafter, the main shapes of the main body 100 and the insertion unit 190 will be described in detail with reference to FIGS. 3 and 4 taken along the line A-A '.

The main body part 100 was processed at a molding (melting) temperature of about 150 to 160 ° C. after mixing 99.9 wt% TPU and 0.1 wt% dye (pigment) in a mass ratio, and the shape of the molding mold thereof. Thereby, the upper portion 103 of the cross section of the hemisphere or semi-elliptic sphere, the central portion 104 in which the circular groove 101 is formed along the lower circumferential surface thereof, and the skirt portion 102 extending in the downward inclined direction from the lower portion thereof. Has

The dyes have almost all colors, including glossy to matte fluorescent colors, white, yellow, blue, and pastel colors, and the road marking bottle of the present invention has a color, texture, and luster to match the environment as well as the formal road. To provide.

In particular, the upper portion 103 has a hemispherical or semi-elliptical cross section without a conventional right angled corner, and has a structurally and geometrically durable round outer shape than a road marker bottle of the prior art in which corner portions are frequently damaged by external impacts. Has a surface.

The circular groove 101 has a vertical width corresponding to the width of the reflective tape 110 and a depth of about 2-3 times the thickness of the reflective tape 110 in the axial direction.

The outer circumferential surface of the circular groove 101 is attached by the adhesive 111 as the reflective tape 110 is wound. At this time, since the depth of the circular groove 101 is slightly deeper than the thickness of the adhesive 111 and the reflective tape 110, as a result, the reflective tape 110 is attached to the inside of the circular groove 101.

The reflective tape 110 reflects light in the direction of all the circumferential surfaces, and is not limited to its role as a reflector, even if a large impact or contact is applied to the main body portion 100 by a tire or an external force of the vehicle. It is a tape attachment structure that can protect (110). In the description of the present invention, the reflective tape 110 may be replaced with a reflective material, a reflector, a reflector and the like.

In addition, the bottom of the skirt portion 102 is formed with a pair of bottom grooves 106 and 107 having a ring shape and a little depth as a diameter smaller than the outer diameter.

The bottom grooves 106 and 107 form concavities and convexities in the bottom surface of the skirt portion 102 of the body portion 100 while reducing the amount of material used, thereby allowing the body portion 100 to have a more stable support base.

Insertion portion 190 is a multi-stage rod shape having a stage extending integrally downward from the shaft center of the skirt portion 102, at least one second portion 192 having a relatively large diameter, and relatively small diameter It has a first portion 191.

Here, the stage between the first portion 191 and the second portion 192 forms an inclined surface, so that the size of the diameter naturally from the first portion 191 having a small diameter to the second portion 192 having a large diameter. It is preferable to have a structure in which is expanded.

In addition, the diameter of the first portion 191 preferably corresponds to the inner diameter of the installation hole of the road. However, when the installation hole is formed slightly larger in actual work, a coagulating substance such as epoxy can be further introduced into the installation hole by means of voids or clearance removal means. Such, the coagulating material is interposed between the installation hole and the insertion portion 190 serves to further strengthen the coupling relationship between the two.

On the other hand, since the insertion portion 190 forms a stage as described above, the first portion 191 can easily enter the installation hole of the road, and then the second portion 192 enters the installation hole at high pressure. The pressing force is transmitted from the main body portion 100 to be pressed, and is forcibly inserted correspondingly to the installation hole while being slightly contracted in the axial direction and almost the radial direction.

At this time, the reason why the second portion 192 of the insertion portion 190 having the high hardness can be forcibly inserted into the installation hole of the relatively small inner diameter depends entirely on the slit shape as follows.

The slit 193 is formed in a straight line at one side circumferential surface of the first portion 191 and the second portion 192 of the insertion portion 190, the skirt portion 102 at the lower end of the insertion portion 190 Extends to.

The depth of the slit 193 is excavated to the extent that the second portion 192 and the first portion 191 are connected to each other in the radial direction. The number of slits 193 is at least one, and the width and length thereof are not limited because they can be implemented in various forms in the present invention.

The cross-sectional shape of the slit 193 is similar to the shape of the semicircle groove, the semi-elliptic groove, and the square groove, and serves as a passage through which air in the installation hole is discharged during the crimping construction, and the elastic insertion portion 190 is easily provided. Serves to allow shrinkage, to provide space for debris (powder, soil, etc.) in the installation hole, to settle in the installation hole with heat deformation such as summer asphalt, and to enter the space When the foreign matter is fixed to each other and acts like a jaw serves to prevent the insertion portion 190 to rotate or twist in the circumferential direction.

In particular, since the inserting portion 190 is molded of the above-mentioned materials, it has a high hardness and has a rubber-like elastic force, and also due to the difference in the diameter of the end and the shape of the slit 193, To be satisfactory in the design, once inserted into the installation hole of the road, it is fixed to the road surface in a completely fixed state without a separate adhesive or fixing means (such as locking bolts).

Second Embodiment

In the drawings, Figure 5 is a cross-sectional view for explaining the configuration of the road marker bottle according to a second embodiment of the present invention.

This embodiment is the same except that a plurality of slits are formed as compared with the previous embodiment.

As shown in FIG. 5, at least one slit 194, 195, and 196, which maintains a predetermined distance in the circumferential direction, extends in the axial direction in the insertion portion 190 protruding to the bottom surface of the main body portion 100, respectively. Formed.

The slits 194, 195, and 196 are very effective when a relatively hard polyurethane insert 190 is inserted into a rugged road installation hole.

That is, as the number of slits 194, 195, and 196 is relatively smaller, the contact ratio between the inner surface of the installation hole of the road and the outer surface of the insertion portion 190 may be relatively easy to install.

However, the outer circumferential portion of the other inserting portion 190 except for the slits 194, 195, and 196 is in close contact with the installation hole of the road, and at the same time, the material (elasticity of the elastomer) and the shape (the end are formed and have slits). The elastic force by) acts sufficiently perpendicular to the inner surface of the mounting hole, whereby it is stably installed and fixed.

In particular, the road marker bottle of the present invention has a solid property and elasticity that maintains a dry state almost no moisture for several hours even at 80 ~ 90 ℃ due to the nature of its material, it is settled in the installation hole Has stable fixing performance, etc.

Third Embodiment

6 is a cross-sectional view for explaining the configuration of a road marker bottle according to a third embodiment of the present invention.

On the outer circumferential surfaces of the first portion 191 and the second portion 192 formed to have a stage in the insertion portion 190, a plurality of protrusions having an oblique shape, a comb pattern, a webbed shape, and an embossing shape in an upward oblique direction 197 protrudes in the radial direction.

This protrusion 197 has a structure that reduces the frictional resistance when pressed into the installation hole of the road. The protrusion 197 is easily inserted into the installation hole while reducing the friction by the first portion 191 and the second portion 192 of the insertion portion 190 by the inclined direction and the protruding distance. Do not fall easily.

Fourth Embodiment

In this embodiment, the same or similar components will be given the same or similar reference numerals for the same or similar configurations, except that the glass grains are integrally combined with the raw material to bind the glass grains to the body portion and the insert portion. .

Figure 7 shows a partial cross-sectional view for explaining the configuration of the road marker bottle according to the fourth embodiment of the present invention.

The main body part 100 and the inserting part 190 are blended with fine glass grain particles 108 in polyurethane, which is a pellet or flake material, before molding.

The compounding ratio is 79.9 wt% of polyurethane, 20 wt% of glass grains 108, and 0.1 wt% of dye.

Dyes can be used as long as they can produce colors, textures and lusters that match the surrounding environment, such as glossy to matte fluorescent colors, white, yellow, blue, and pastel colors.

The glass grain particles 108, which are reflective materials, are used as a means for increasing the reflection efficiency of the entire body portion 100. Herein, the glass grains 108 are about 300 mesh thick, blended with a material, and then molded to have a uniform distribution throughout the main body 100 (inside and outside). The glass grain particles 108 are arranged to be minutely but slightly expressed not only inside the main body 100 but also to the outside.

Therefore, the road marker bottle according to the fourth embodiment maximizes the reflection efficiency for the light by the fluorescent dye and the glass grain particles 108 externally exposed, even if there is no reflective tape.

Fifth Embodiment

In this embodiment, through the form of applying the configuration of all the above embodiments, it will be described for the road marker bottle that can be more easily installed and maximize the reflection efficiency.

8 is a partial cross-sectional view for explaining the configuration of the road marker bottle according to the fifth embodiment of the present invention.

The road marking bottle has a body portion 100 and an inserting portion 190 in one piece by mixing the glass grain particles 108 and dyes of various colors in a polyurethane material at a predetermined mixing ratio, wherein the body portion 100 ) Has a hemisphere, an upper portion 103 of a semi-elliptic sphere shape, a central portion 104 of a circular groove 101 shape, a skirt portion 102 inclined in a downward inclined direction, and the insertion portions 190 end with each other. And a first portion 191, a second portion 192, and a surface protrusion 198.

The reflective tape 110 is attached to the circular groove 101 of the main body 100 by an adhesive, and is fixed to the inside of the circular groove 101 so that no external force or impact is transmitted directly. .

The surface protrusions 198 are arranged such that minute rod-like protrusions protrude from the surface.

The surface protrusion 198 extends in the radial direction (radiation direction) relatively longer than the diameter of the first portion 191 or the second portion 192 to facilitate installation.

The surface protrusion 198 may further generate a relative bearing force in the radial direction by the protruding length.

On the other hand, the shaft of the insertion portion 190 may be further formed with a hollow of the concept contrasted with at least one previously formed slit, the hollow may extend to the inside of the body portion 100 as well as the insertion portion 190. Can be.

In particular, when the fixing material for concrete is inserted in the form of a tube into the hollow, and the inserting portion 190 is pressed into the installation hole, the fixing portion is compressed and ruptured as if the tube is squeezed by the elastic deformation of the inserting portion 190. It may further provide a construction structure in which the material flows into the installation hole.

On the contrary, when the fixing material is first inserted into the installation hole, and then the inserting portion 190 is pressed into the installation hole, the construction structure allows the fixing material to enter the hollow interior. The furnace insert 190 may be installed in the installation hole.

Sixth Embodiment

This embodiment is the same as the above-described embodiments except that the transparent ring portion is integrally formed by the double injection molding in the circular groove 101 of the body portion.

9 is a perspective view and an enlarged view for explaining the configuration of the road marker bottle according to a sixth embodiment of the present invention

The adhesive groove 111, the reflective tape 110, and the transparent ring portion 120 are sequentially arranged in the circular groove 101 of the main body portion 100.

At this time, the depth of the circular groove 101 with respect to the body portion 100 is deep enough to form some grooves or tuck in the outer portion of the transparent ring portion 120.

The road marker bottle of the present invention is manufactured by the following manufacturing procedure.

First, the worker mixes the glass grains 108 and dyes of various colors with a predetermined blending ratio in a polyurethane material.

Thereafter, the circular upper portion 103, the circular groove 101, the skirt portion 102 to the main body portion 100, the first and second portions 191, 192 forming a stage to the insertion portion 190, Various protrusions (protrusions) are prepared on the surface of the insert 190, or a first mold (mold) capable of forming hollow or surface-shaped slits on the insert 190.

In addition, the operator prepares a second mold configured to correspond to the first mold, but configured to be integrally molded in a separate transparent ring portion where the circular groove 101 is to be formed.

In addition, a first molding material is prepared by blending a reflector including glass particles and dyes of various colors with a material having high hardness plastic properties and elastic rubber properties including a polyurethane material at a predetermined blending ratio, and preparing a transparent synthetic resin to poly A second casting material made of urethane material is prepared.

Subsequently, the worker manufactures the basic road marking bottle in which the main body 100 and the inserting portion 190 are integrally formed by molding the first mold material in the first mold. After the adhesive 111 is applied very minutely to the circular groove 101 of the basic road marker bottle, the reflective tape 110 is attached to the upper portion of the adhesive 111.

Here, the role of the adhesive 111 is merely used so that the reflective tape 110 does not fall from the circular groove 101 during the injection molding, which is a long time the reflective tape 110 to the circular groove 101 It is a different concept from the adhesive means for making it available for time. That is, when the reflective tape 110 made of a ring shape is inserted into the circular groove 101, the adhesive 111 is not necessary. This is because the transparent ring portion 120 to be described below is used as the main restraining means for preventing the reflective tape 110 from falling off from the circular groove 101.

In any case, the basic road marking bottle having the reflective tape 110 disposed in the circular groove 101 is inserted into the second mold, and the second mold material is introduced into the second mold to perform the second injection molding. .

At this time, by the structural shape of the second mold, the second mold material is injected and heated to contact the upper and lower inner surfaces of the circular groove 101 of the body portion 100, and as a result, integrally with the circular groove 101 It becomes the integrated transparent ring portion 120.

Meanwhile, the transparent ring portion of the road marking bottle may be attached and coalesced in a structure integrated into the circular groove 101 of the main body portion 100 by any other molding method as well as double injection molding. Separately, the transparent ring portion 120 Only by separately manufacturing it is also possible to fit in the circular groove 101 by fitting.

In addition, the separately produced transparent ring portion 120 is fitted into the circular groove 101, it may be fixed integrally to the body portion 100 even if not double injection molding by high frequency bonding, ultrasonic bonding.

In addition, for the purpose of achieving the same purpose as the transparent ring portion 120, that is, to protect the reflective tape 110, the transparent material is coated or laminated on the inside of the circular groove 101 to the trademark surface of the reflective tape 110 At least one transparent layer layer may be further formed on the reflective tape 110 by any bonding, attaching, or fixing method.

The transparent ring portion 120 serves to protect the reflective tape 110 seated in the circular groove 101, and serves to increase the reflection efficiency.

Hereinafter, the technical configuration of applying the configuration of the embodiments to the vertical road marker bottle will be described with reference to FIGS. 10 to 12.

As shown in Figure 10 and 12, the vertical road marker bottle is formed of a material of polyurethane, glass powder, color pigments, yellow bar, white bar, green bar, etc. 200, and a support-shaped insert 290 that can be disassembled and assembled by a coupling means 299 such as a fixing bolt, an anchor bolt, or a coupling bolt to the main body 200.

The main body 200 of the vertical road marker bottle is a reflection material (208: glass powder) is mixed with the entire body to enhance reflection efficiency, or a combination of dyes of various colors (transparent and fluorescent), and reflection Together with the tape 210, the reflection efficiency is further configured.

In particular, at least one circular groove 201 extending in the circumferential direction is formed on the outer circumferential surface of the main body 200 so that the reflective tapes 210 are formed in the circular groove 201. At the same time it is seated, it is attached by an adhesive, or secured by the transparent ring portion 220 as described above.

Since the upper end of the main body 200 is formed in a cone shape, it has a considerably more beautiful shape than the conventional simple rod shape, and since rain water flows well on the upper cone shape where dust and the like are difficult to accumulate, The advantage is that the appearance does not get dirty.

Insertion portion 290 is inserted into the inner diameter of the lower end of the hollow body portion 200 serves to support the body portion 200 on the road surface, the disk portion 297, at the upper axis of the disk portion 297 It has an integrally extending support 298 of the shaft, a first portion 291, a second portion 292, at least one slit 293, and various surface projections similar to the previous embodiments. It is easy to install and install and provides strong fixing structure.

In particular, the support 298 is a circular solid axis, for example, a diameter of 25 pi (φ) and a height of 350 mm, which can be adjusted as necessary.

As an elastic body that generates a bearing force and a restoring force against an external force applied to the hollow body portion 200, it serves as a shock damping of the hollow body portion 200.

That is, the support 298 assists the elasticity of the hollow body part 200, and when the vehicle collides with the center line, it can absorb the shock and remarkably reduce the vehicle bounce off. Helps to prevent the secondary accident by the action, it is to act to significantly reduce the bending or breaking the hollow body portion 200.

In addition, the road marker bottle provided in the present invention, including the normal and vertical road marker bottle described above, it is preferable that the coating film is further formed to block contact with moisture, moisture, etc. on all outer surfaces (including the transparent ring portion). Do.

In the following, through Fig. 13 to 15, it will be described the construction method of the road marker bottle of the present invention

The contractor marks the position for installing the road marker bottle of the present invention on the installation position such as road, ground, road surface 4, etc. in advance, and then carries out the construction for drilling the installation hole 5 on the installation surface. (S10).

After each installation hole 5 is formed on the installation surface, a cleaning operation is performed to remove foreign matter remaining in the installation hole 5 as much as possible by using a blower, blower, vacuum cleaner, electric brush, and water cleaning equipment (S20). ).

Thereafter, the worker gently holds the main body 100 by hand and fits the first portion 191 of the insertion portion 190 in accordance with the inner diameter of the installation hole 5 (S30).

Since the diameter of the first portion 191 is substantially the same as the inner diameter of the installation hole 5 in view of the shape, and also has an elastic force in the nature of the material, it is easily inserted into the installation hole 5 without applying excessive force.

Thereafter, the contractor matches the operating parts of the construction equipment such as the presser and the compressor to the shaft center of the main body 100, and then the axial compression force applied to the main body 100 is transmitted to the insertion unit 190 ( S40).

At this time, the second portion 192 of the insertion portion 190 forms a step or has an inclined surface, and enters the installation hole 5 in a force-fitting manner by the pressing force in the axial direction. At the same time as the internal air in the mounting hole 5 escapes along the slit 193, the second portion 192 of the insertion portion 190 has a diameter corresponding to the internal space of the slit 193. It causes elastic deformation toward shrinking (S50).

By the elastic deformation and the axial compressive force continuously transmitted, the insertion part 190 is completely fixed to the installation hole 5, and the second part 192 of the insertion part 190 has a diameter depending on the material and shape. By applying the pressing force in the direction to the installation hole 5, it is fixed to the installation hole 5 (S60).

Once the fixed insertion portion 190 has lost the axial pressing force, the pressing force in the radial direction, and stone powder made when pressed into the mounting hole 5 are collected in the slit 193, thereby providing an installation hole ( 5) It is fixed not to shake, rotate or come off.

In addition, in response to thermal stresses or residual stresses generated in asphalt, road surface, ground, etc., the insertion part 190 has an end on the outer circumferential surface, and plastic and elastic properties due to the polyurethane material. While being deformed to correspond to the inner surface of the fixed position takes place (S70).

Hereinafter, the body portion 100 of the road marking bottle of the present invention is also preferably fixed to the mounting hole 5 by a heat fusion construction method.
