The present invention relates to a traffic sign device used for indicating various regulations, instructions, and cautions necessary for safe road operation mounted on a pillar on a road, or for indicating location information of a road or a building And more particularly, to a traffic sign device capable of firmly and easily installing a plurality of signs on a single support as well as facilitating replacement at the time of breakage.

Generally, on the edge of the road or the upper part of the road, the driver and the pedestrian are informed of various kinds of danger that may occur on the road, thereby securing a safe and smooth road bridge, and at the same time, Road markings are provided to indicate various items necessary for the use of roads.

These road signs are installed and produced according to the law, and represent the contents to be transmitted in the form of letters, graphical symbols, or combinations thereof.

It is divided into a warning sign that notifies the dangerous state of the road or necessary attention according to the nature of the message, a regulatory mark that regulates certain behavior against the pedestrian or the vehicle, and a sign that directs the action or the spot.

Therefore, the road sign should be easy to recognize, and it should be possible to identify the type of sign in a long distance and to grasp its contents in a short time. In addition, since it must be able to be read at night, it should be appropriately arranged for the purpose.

On the other hand, on the road, there are provided various kinds of information related to the road, such as the road direction, the distance, the location, and the like, in addition to the road sign.

Such road markings and guide signs (hereinafter collectively referred to as "traffic signs") are classified into two types according to the size of a road: a single column type which is supported by a cantilever in a form of a cantilever, It is installed in a different type of restorative type attached to a horizontal bar that connects two struts. Usually, a flat stock is used except for the highway.

FIGS. 1A and 1B show the most general configuration of such a one-piece traffic marking apparatus. This is because a T-shaped hanger 2 is horizontally bound by a band clamp 1 at an appropriate height position of the column P standing on the road and the hanger 2 is horizontally joined to the back surface of the sign plate 3 A plurality of U-bands 5 are hooked on the hanger 2 and the flanges 6 at both ends of the bolts 7 are fastened to the bolts 7 of the sign board 3, (3) is provided on the support (P) by fastening the guide plate (7) with the nut (8).

Conventional traffic sign devices having such a configuration can also be found in, for example, Korean Unexamined Patent Application Publication No. 1999-0079008 and Registered Utility Model Registration No. 20-0195042.

Such conventional traffic sign devices are used to connect the hanger 2 to the pillars P and to assemble the bolts 7 to the respective guide rails 4 provided on the back surface of the sign 3, 2, the U-bands 5 must be fastened to the bolts 7 by means of the nuts 8, so that the installation work is considerably troublesome.

In addition, since the sign 3 is formed in a thin plate shape and the fastening guide rail 4 and the bolts 7 are exposed to the outside, there is a problem that the appearance is considerably poor and the aesthetic appearance of the road is greatly damaged.

Further, since the hanger 2 is welded to the outer periphery of the band clamp 1, there is a high possibility that the welded portion will fall down due to oxidation corrosion over a long period of time. In particular, when two or more signs at one place must be simultaneously installed (3), the hanger (2) and band clamp (1) must be replaced in their entirety.

Various types of traffic sign devices for solving such problems are proposed, for example, Korea Utility Model Registration No. 1996-0009278.

In this technique, a cover panel is constituted by a pair of synthetic resin members, bosses and protrusions are formed on the divided bodies, and they are assembled together by fitting, and a holding insert boss is provided on the inner surface of each divided body, However, since the sign board is assembled by fitting, there is a concern that it is likely to be disassembled due to external force, and it is easily deformed and the strength is also weak.

On the other hand, Korean Patent Registration No. 0358988 discloses a first invention of the present applicant, in which a hanger is fastened to a post clamp in a prefabricated manner, and a connecting plate and a fixing bracket fastened to each other at the rear end of the hanger and the sign board, A traffic sign device technology has been proposed in which only the corresponding part can be easily replaced at the time of breakage and the aesthetic appearance can be improved.

However, this technique requires only one sign for one hanger because the sign is directly orthogonal to the free end of the hanger, so if you need to install several signs at the same point, you need to install a post clamp and hanger Depending on the number of signs, there are several problems to install each one, which is not good for cosmetics.

SUMMARY OF THE INVENTION The present invention has been made to overcome the above-described problems of the prior art, and it is an object of the present invention to provide a sign post which can be easily installed on a support, The present invention provides a traffic sign device capable of installing two signs together.

It is another object of the present invention to provide a traffic sign device which can easily install a desired number of signs on a single post clamp and a hanger by simply replacing the hangers according to the number of signs to be installed.

In order to achieve these objects, a traffic sign according to the present invention comprises two arcuate clamping bands, one end of which is hinged to each other, and the other end is fastened by fastening means A post clamp engaged; A fixing pipe having one end joined to the outer periphery of one clamping band of the post clamp in a radial direction, a horizontal bar having one end inserted into the fixing pipe and fastened by the fastening means, A hanger comprising a T-shaped movable pipe having a vertical bar; A plurality of signs having a cap-like fixing bracket having a plurality of fastening holes printed on a front surface thereof, And a plurality of fixing bands having flanges fixed to the fastening holes of the fixing bracket by bolts at both ends of an arc-shaped body corresponding to the vertical bar outer shape of the hanger to fix the respective marking plates to the vertical bars of the hanger, respectively .

According to a preferred aspect of the present invention, a cylindrical insertion holder is vertically joined to the other end of the horizontal bar of the movable pipe of the hanger, and a vertical bar to which the sign is fixed is inserted into the insertion holder and fastened with the bolt.

Accordingly, it is possible to easily install the signboard on the support while easily replacing the corresponding part only in the case of breakage, and it is possible to easily install a plurality of signboards together with one post clamp and hanger as necessary.

In addition, according to the number of signs to be installed, only the hanger can be easily replaced, so that a desired number of signs can be easily installed in one post clamp and a hanger, so that the sign of the traffic sign, do.

These and other features and advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

A slit is formed axially in the middle of the inner periphery of the first clamping band 11 to form a contact protrusion 40 for resiliently pressing the pillar P when fastened to the pillar P. [ The contact protrusion 40 prevents the clamp 10 from flowing or rotating due to a gap between the post clamp 10 and the support post P that may be generated when the support post P is formed in a square shape It is for this reason.

Therefore, the contact protrusions 40 can be detachably mounted and selected according to the shape of the pillars P, and even if the circular pillars P have a small difference in the diameters of the pillars P, (P). The contact protrusion 40 is preferably made of a rubber material having appropriate elasticity.

A hinge protrusion 16 is formed at one end of the second clamping band 15 and is rotatably inserted into the hinge groove 12 of the first clamping band 11. A plurality of fastening holes 17a are formed at the other end, The flange 17 is formed. Needless to say, a slit may be formed in the inner circumference of the second clamping band 15 in the axial direction so that a contact protrusion may be provided.

On the upper and lower sides of the outer periphery of the fixed pipe 21, reinforcing ribs 27 for supporting the post clamp 10 in a stable manner are preferably welded to each other.

The reinforcing rib 27 has an engaging projection 27a at one side edge thereof and is fitted into the engaging groove 14a of the supporting land 14 so that one edge of the reinforcing rib 27 adjacent to the engaging projection 27a is engaged with the outer periphery 23b formed in the upper and lower sides in the axial direction, respectively.

The movable pipe 24 includes a horizontal bar 24a whose one end is movably assembled to the fixed pipe 21 and is fastened by a bolt 28 and a vertical bar 24a which is connected to the other end of the horizontal bar 24a 24b.

The horizontal bar 24a of the movable pipe 24 is relatively longer than the fixed pipe 21 and a plurality of fastening holes 24c are arranged at regular intervals along the axial direction. The length of the entire hanger 20 can be appropriately expanded or contracted by changing the fixing position of the movable pipe 24 with respect to the fixed pipe 21 as necessary.

The hanger 20 is also manufactured by extruding a nonferrous metal material such as aluminum, which is excellent in corrosion resistance.

The sign 30 is formed of, for example, a plate made of an aluminum material excellent in corrosion resistance, and is formed into a square shape such as a circle, triangle, or pentagon, which is determined according to the law according to the properties of the cover material (for example, As shown in FIG.

A skirt 31 for reinforcing the strength is appropriately extended rearward at the edge of the sign 30. The skirt 31 improves the strength of the sign 30 and improves the appearance of the sign 30 by appropriately blocking side exposure of the sign fixing means 50. [

A fixing bracket (32) for fastening the fixing band (50) is welded to the center of the back surface of the sign board (30). The fixing bracket 32 is made of aluminum and has a substantially cap-like shape having a flange 33 for jointing at its opening end. Accordingly, a certain space is formed between the mark 30 and the fixing bracket 32 to shield one of the external exposures of the bolt fastening portion.

At this time, the fixing bracket 32 may weld the edge of the flange 33 to the mark 30, but in order to achieve a more stable bonding force, a plurality of welding slots 33a are formed at appropriate intervals on the flange 33 And welded to the sign 30 through each welding slot 33a.

A plurality of fastening holes 34 are horizontally spaced from each other in the fastening bracket 32. Fastening nuts 35 are forcibly inserted and fixed to the inner surface of the fastening bracket 32 so that the bolts 60 are rotated A nut fastening channel 32a is provided for preventing the fastening of the nut.

The fixed band 50 includes an arc-shaped body 51 for partially covering the vertical portion 24b of the movable pipe 24 of the hanger 20 and pressing the same, A fixing bracket 32 joined to the back surface of the flange 30 and a flange 52 fastened with bolts 60 respectively.

The body 51 has a shape corresponding to the contour of the vertical bar 24a to which the sign 30 is to be fixed and the structure shown in the figure is the same as the case where the hanger 20 is circular Which is approximately semicircular. A fastening hole 53 through which the bolt 60 passes is formed in the two flanges 52.

In the meantime, preferably, a dovetail type coupling channel 54 is formed in the middle of the body 51 so as to protrude outward while being opened to the inside, and a dovetail 56 is projected on one side of the coupling channel 54 And the slip prevention pad 55 protruding from the inner periphery of the body 51 is slidingly coupled.

The slip prevention pad 5 is configured to have a proper width so as to contact only a part of the vertical bar 24b.

It is preferable that the slip prevention pad 55 is formed of a material having a high friction coefficient and is preferably compressively deformed when the fixing band 50 is fastened to the fixing bracket 32 of the sign 30 by the bolt 60 And is made of a soft rubber material having appropriate elasticity so as to be elastically brought into close contact with the vertical bar 24b of the hanger 20. [

The traffic sign system according to the present invention having the above structure is constructed so that the post clamp 10 with the fixing pipe 21 of the hanger 20 and the movable pipe 24 and the fixing bracket 32 of the hanger 20 are joined And assembled into a three unit assembly of the sign board 30 or assembled into two assemblies of the post clamp 10 and the sign 30 assembled up to the movable pipe 24 in the stationary pipe 21, And is installed in the column P as shown in Fig.

The sign 30 is fixed to the movable pipe 24 by the fixing band 50 in a state where the post clamp 10 is fastened to the support P and then the movable pipe 24 is fixed to the fixed pipe 21. [ Or simply by fastening the post clamp 10 to the support pillars P and then fastening the fixing band 50 to the fixing bracket 32 bonded to the sign board 30 with the bolts 60 The installation can be completed only by a very simple operation to be performed.

In addition, since the post clamp 10 is composed of two arc-shaped clamping bands 11 and 15 connected to each other by a hinge, mounting of the post clamp 10 to the post P is very simple, The work becomes very easy.

Of course, it is also possible to arrange the mark 30 at an optimum position by appropriately selecting the fixing position of the movable pipe 24 with respect to the fixed pipe 21 in consideration of the condition of the installation site and the like.

In addition, the traffic marking apparatus of the present invention is configured such that the fixing bracket 32 attached to the sign 30 is formed in a cap shape so that the exposure of the fixing bracket 32 is completely prevented by accommodating one side of the fastening portion of the bolt 60, The sign board 30 is fixed only by the cover 50, and the appearance improvement can be expected.

In particular, even when two or more sign boards 30 are installed in one place, two or more sign boards 30 can be easily installed on one hanger 20, and three or more sign boards 30 can be easily installed in one place The movable pipe 24 can be simply replaced with another movable pipe 24 having a longer length of the vertical bar 24b and fastened to the fixed pipe 21, The sign boards 30 can be installed together.

This also makes it possible to easily remove and replace only the movable pipe 24 from the fixed pipe 21 even if the sign 30 or the movable pipe 24 is damaged due to a physical impact from the outside.

In addition, the present invention is characterized in that a slip prevention pad 55 made of rubber having a large friction coefficient is provided so as to protrude from the middle of the inner periphery of the body 51 of the fixing band 50, The slip prevention pad 55 is resiliently pressed against the vertical bar 24b of the hanger 20 while being compressed and deformed by the pressing of the fixing band 50. [

This makes it possible to maximize the frictional force with the vertical bar 24b so that the mark 30 is firmly fixed and the slip of the fixing band 50 with respect to the vertical bar 24b can be surely secured even when an external force is applied to the mark 30 So that the sign 30 does not flow or rotate.

In addition, since each component is made of a non-ferrous metal material having excellent corrosion resistance, oxidation corrosion does not occur, and maintenance is also simplified since there is no need to perform painting periodically as in the past.

7 shows another embodiment of the traffic sign system according to the present invention. In this embodiment, the vertical bar 24b of the movable pipe 24 of the hanger 20 has an elliptical cross section .

The embodiment of such a configuration can more reliably prevent rotation of the sign 30 by an external force, and can reliably ensure the reliability and recognizability of the traffic sign.

8 to 10 show another embodiment of the traffic sign device according to the present invention.

[

When the bolts 73 are fastened to the vertical bars 24b through the threaded holes 71, the elongated bolts 73 are inserted into the insertion holes 70. As a result, The screw hole 71 of the insertion holder 70 which is relatively weaker than the bolt 73 is easily worn by an external force such as wind which is applied to the sign 30, The fastening force of the bolt 70 is weakened and a flow is generated, so that the bolt 73 can be detached in severe cases.

10, a so-called helical coil 74 made of a hard metal is coupled to the screw hole 71 of the insert holder 70 so that the inner and outer peripheries of the screw hole 71 are all screwed together. do.

The helical coil 74 is wound in a coiled shape with a rhomboidal cross section. When the bolts 73 are engaged, the respective windings are minutely opened in the axial direction, So that the fastening force is increased to reliably prevent the general bolt 73 from being loosened.

The helical coil 74 is preferably made of stainless steel having excellent mechanical strength and corrosion resistance.

In this embodiment, only the horizontal bar 24a of the movable pipe 24 can be transported to the site in a state where the horizontal bar 24a is assembled to the fixed pipe 21. This not only facilitates transportation and handling, The horizontal bar 24a can be simply replaced with the vertical bar 24b in the state of being in the same state, which is advantageous for reducing the maintenance cost.

Although the present invention has been described in connection with the case where the post clamp is composed of two clamping bands, it is to be understood that the present invention is not limited thereto but may be modified in various ways.

For example, although not separately shown, at least one auxiliary clamping band having a small arc length formed with hinge grooves and hinge protrusions at both ends may be further provided to selectively support the first and second clamping bands according to the diameter of the strut They can be connected to each other via clamping bands, or the post clamp can be divided into two or more clamping bands.

In this case, it is possible to easily mount the post clamp on all the supports regardless of the diameter of the support.
