Korea Utility Model Registration No. 20-0400225

The present invention relates to a support device for a sign, and more particularly, to a support device for a traffic sign for stably supporting a traffic sign for road traffic. However, it is not limited to traffic signs for road traffic.

The traffic sign is installed on the road and is a device that allows traffic to be informed of traffic conditions and conditions of traffic so that traffic can pass safely. The traffic sign is a form for assisting the operation of the vehicle, which is installed in the vertical direction on the runway extending from the vertical stand on the corner of the road, and installed directly on the vertical stand on the corner of the road to drivers and pedestrians There are also forms that help directly.

However, the signs are often broken by external shocks such as a collision of the vehicle, or strong wind pressure. In this case, there is a problem in that the sign is not bent, the installation position is changed, or a phenomenon such as falling off the crossbar occurs, thereby failing to perform the original function as the sign.

In view of such a conventional problem, the applicant of the present invention has already proposed the Republic of Korea Patent No. 10-586627 (Citation Document 1). However, since the patent has to change the structure of the crossbar, it is difficult to apply the actual product, and because the structure itself is complicated, the actual application is difficult, and the elastic force is so large that it cannot cope with external shocks, There was a frequent problem of being broken.

In order to improve this problem, the applicant has further applied for the Republic of Korea Utility Model Registration No. 20-0400225 (quotation 2). However, according to the cited reference 2, since the crossbars (referred to as supporting rods in the cited document 2) have to be drilled, there is a disadvantage that a direct flaw remains on the crossbars, and in the event of a backwind, the signs are eventually damaged and replaced. There is a disadvantage to that. In addition to this, since the sign angle is small, there is a problem that the sign may be broken by a vehicle having a high vehicle body, and a separate screw 16 must be assembled, and the bolt 50 and the nut 51 Since tightening), the fastening process is difficult. And, since a separate stopper 90 has to be provided, there is a disadvantage in that the configuration is complicated, and since the distance between the crossbar and the sign 40 is not stable, the sign cannot be stably supported.

The present invention has been proposed to improve the above problems, and provides a sign support apparatus that is stably supported even against strong wind pressure, the structure is simple, the fastening and installation are simple, and the deformation of the crossbar does not occur.

In addition, if the wind pressure is applied to the front of the sign, as well as to provide a sign support device that can prevent damage to the sign even when applied to the back of the sign.

In addition, the rotation angle of the sign to the external wind pressure is maximized, suggests a sign support device that the height to prevent the sign is damaged in the event of a collision, such as the vehicle is increased so much.

According to another aspect of the present invention, a sign support device includes: a fixing assembly mounted to a sign and installed on a support having a predetermined height; And a soft friction member fitted to a contact portion of the fixing assembly and the support, wherein the fixing assembly includes: a fixing plate fixed to the sign; A first noise plate that substantially hugs and presses the soft friction member, and at least one point is in contact with the fixed plate to prevent reverse rotation of the fixed plate; A spring providing a force for pulling the fixing plate and the first noise plate together; A second noise plate fastened to the first noise plate; And at least one hinge that allows the fixed plate, the first noise plate, and the second noise plate to be hinged with each other.

According to another aspect of the present invention, a sign support device includes: a fixing assembly mounted to a sign and installed on a support of a predetermined height; And a soft friction member inserted into a contact portion of the fixing assembly and the support, wherein the fixing assembly includes: a fixing plate fixed to the sign; A first noise plate having the soft friction member installed therein; A spring providing a force for pulling the fixing plate and the first noise plate together; A second noise plate fastened with the first noise plate to provide a strong friction force between the soft friction member and the support; And a hinge which is directly formed at the lower end of the fixing plate to allow the first noise plate and the second noise plate to be rotatable with respect to the fixing plate.

Sign support device of the present invention according to another aspect, the support is placed at a certain height; And a fixing assembly installed on the support in a state in which the sign is mounted, wherein the sign includes: an installation guide formed to be long in one direction on a rear surface of the sign; And a locking jaw formed at a predetermined position of the installation guide, the fastening member being inserted into the internal receiving space of the installation guide to a position to be caught by the locking jaw; And another fastening member engaged with the fastening member in a state in which the fastening member is related to at least a part of the fastening assembly to fix the sign and the fastening assembly therebetween at a predetermined height.

By the configuration as proposed, the sign can be easily installed, and the sign can be firmly supported by the simple configuration. In addition, the sign can be firmly supported against the external wind pressure, it can be expected that the breakage of the sign is prevented even when a high vehicle crash.

Hereinafter, with reference to the drawings will be described in detail the configuration of the present invention. However, the spirit of the present invention is not limited to the accompanying embodiments, and those skilled in the art who understand the spirit of the present invention can easily add, change, delete, and add other embodiments included in the scope of the same idea. It may be suggested that the present invention is included in the present invention.

1 is a schematic side view of a sign supporting apparatus according to the present invention installed.

Referring to FIG. 1, the sign support apparatus according to the present invention includes a crossbar 1, a soft friction member 7 installed to surround the crossbar 1, and a soft friction member 7 wrapped around the soft friction member 7. (7) and the crosspiece (1) are in close contact with each other to provide a pressure for generating a friction force between the first noise plate (4), the second noise plate connected to the first noise plate (4) and the hinge (2) 5 and the fixing plate 3 are provided as main components. In addition, a spring 6 is connected to the fixed plate 3 and the first noise plate 4 to provide a force in a direction in which the fixed plate 3 and the first noise plate 4 are always in contact with each other. It can be easily seen that the mounting state of the spring 6 provides a force so that the fixing plate 3 is maintained perpendicular to the crosspiece 1. Of course, the installation angle of the sign 9 of the crosspiece 1 may be installed to be inclined downward to some extent within the range for the driver to see conveniently, but this is also included in the spirit of the present invention.

In addition, it can be easily seen that the front of the fixing plate 3 is provided with a sign 9 of a predetermined shape to allow the fixed plate 3 and the sign 9 to move integrally.

When the wind blows from the left side or the vehicle collides with reference to the drawing, the sign 9 is rotated counterclockwise based on the drawing and is displayed as a virtual line in the drawing. Is rotated. As a result, the sign 9 can be prevented from being damaged by the external wind pressure, and even after the vehicle collides, the sign 9 is returned immediately after the sign 9 is rotated by the force of the spring 6. The sign 9 can be prevented from being broken.

On the other hand, it may be assumed that the wind blows from the right side or the vehicle collides with reference to the drawings, but such a case may hardly exist because the vehicle moves only from the front of the sign 9 to the rear.

And, when the wind pressure is applied from the rear of the sign 9, because it provides a force to resist the wind pressure by the frictional force of the contact surface between the crossbar 1 and the soft friction member 7 to a certain degree, it is supported stably Can be. Thereafter, by the friction force between the crossbar 1 and the soft friction member 7-by adjusting the engagement position and the coupling force of the noise plate-with respect to the crossbar 1 before the sign 9 is damaged by the wind pressure. The soft friction member 7 is rotated. In other words, when the sign 9 cannot be supported by the reverse wind, the soft friction member 7 is rotated with respect to the crossbar 1 by the wind pressure applied to the sign, so that the sign 9 is applied even if the wind pressure is applied. ) Is rotated in a clockwise direction without being damaged, so that the operator only needs to rotate the soft friction member 7 counterclockwise with reference to the drawings. In this embodiment, the force received from the lower portion relative to the crosspiece 1 when the wind is large, and the background is rotated in the direction in which the lower portion is rotated upward. Of course, it will of course be understood that the sign 9 can be rotated in the same manner in the reverse case.

Such a concept was not possible in the first place due to the fastening of bolts or the like between the article corresponding to the crossbar and the article corresponding to the first noise plate according to the related art, but the crossbar 1 and the soft friction member 7 according to the present invention. This is possible because relative rotation is prevented only by the pure frictional force without any fastening tool between the parts.

In addition, the first noise plate 4 is provided in a form in direct contact with the fixed plate 3 to prevent clockwise rotation of the sign 9. In this way, since the two are in direct contact with each other, there is no need to provide a separate spacer as in Reference 2, and the structure can be simplified, and the distance between the sign 9 and the crossbar 1 can be shortened. There is an advantage that can be prevented from breaking the support device of the sign by its own moment directed downward of the sign. In addition, when the strong wind pressure is applied, by preventing the occurrence of turbulence generated independently of each other at the periphery of the crossbar 1 and the sign 9, both can act as a single body, so that the sign 9 also has a strong wind pressure. It can be supported more stably.

In addition to this, as shown in the drawing, the second noise plate 5 is provided in the form of being bent once. Since the crossbar 1 can be supported at two points by being provided in such a structure, Coupling force between the crossbar 1 and the soft friction member 7 can be increased, there is an advantage that it is stably supported. In addition, since the first noise plate 5 does not extend downwardly from the hinge 2, it is possible to obtain an advantage that the fixing plate 3 does not act as an obstacle when the fixing plate 3 is rotated almost at right angles.

On the other hand, the relative position that the sign 9 is fastened to the fixed plate 3 will vary depending on the shape of the sign, which is rotated counterclockwise relative to the drawing only when a certain wind pressure is applied, In the case of not strong wind pressure, the sign 9 is not rotated so as not to disturb the driver's traffic. For example, in the case of the triangular sign 9, even if the fixing plate 3 is installed at a medium height, since the lower area of the lower sign is wide, the sign 9 only when a certain external wind pressure is applied. Can be rotated. However, in the case of the inverted triangle sign 9, the fixed plate 3 should be installed on the upper side of the sign 9, so that the area under the sign widens around the hinge 2 so that the sign for a constant external wind pressure This can be rotated smoothly.

As such, the structure for allowing the fixing plate 3 to be conveniently installed at a predetermined position of the sign 9 will be described later in detail with reference to FIGS. 5 to 7.

The sign supporting device according to the present invention will be described in more detail using a perspective view of the soft friction member in the disassembled state in the sign supporting device shown in FIG. 2 and an exploded perspective view of the fixing assembly shown in FIG. 3.

2 and 3, the soft friction member 7 is provided to be separated from the fixing assembly 10, and the fixing assembly 10 includes a fixing plate 3 to which a sign 9 is fixed, The crossbar 1 and the soft friction member (1) in a state where the soft friction member 7 and the crossbar 1 are placed inside the first noise plate 4 and the first noise plate 4 provided in an arc shape. A second noise plate 5 is provided to fix 7) with a strong frictional force, and the fixed plate 3 and the first noise plate 4 and the second noise plate 5 are rotated relative to each other by the hinge 2. This leads to a possible form.

In detail, the hinge 2 has a hinge shaft 21, the hinge shaft 21 is fitted into the hinge plate 21, and a fixing plate side hinge shaft guide 24 formed on the fixing plate 3, and the first noise. A first noise plate side hinge axis guide portion 23 formed in the plate 4 and a second noise plate side hinge axis guide portion 22 formed in the second noise plate 5 are included. The hinge shaft guides 22, 23 and 24 are integrally formed with the respective members so that the direction in which each member extends with respect to the hinge shaft 21 is determined by itself, as shown in FIG. Will be described in detail later.

The structure of each member mentioned above is demonstrated in detail.

The fixing plate 3 is formed with a plurality of slits for inserting the bolt to fasten the sign and the fixing assembly 10, the first upper slit 31, the second upper slit 32 and the lower slit 34 It is. The lower slit 34 is a portion in which a fastening member such as a bolt is always fitted, and the lower side of the fixing plate 3 is fastened to the sign 9. In addition, the first upper slit 31 and the second upper slit 32 are portions into which a fastening member such as a bolt is selectively fitted according to the shape of a sign. For example, in the case of a sign in which the fixed plate 3 is to be installed at the intermediate position of the sign 9 as in the case of an equilateral triangle sign, the fastening member is inserted into the first upper slit 31 at a high position. Be sure to On the contrary, in the case of a sign that the fixing plate 3 is to be installed at a position approximately above the sign 9 as in the case of the inverted triangle sign, the fastening member is inserted into the second upper slit 32. The reason why the fastening member is fastened to the second upper slit 32 provided below the first upper slit 31 in the case of the inverted triangular sign is, in the case of the general sign 9, an installation guide having a certain length ( 1, 8) is formed up and down. When the fixing plate 3 is to be installed high, such as an inverted triangle sign, the first upper slit 31 is the installation guide (see 8 in FIG. 1). This is because it is positioned above the upper limit of. Therefore, without changing the basic structure of the existing installation guide is a configuration required to ensure that the fixed plate is installed while being interchanged.

Below the second upper slit 32, the first spring fixing part 33 is provided in a form including a circular through hole, and one end of the spring 6 is fitted inside the through hole. Since one end of the spring 6 is provided in a form in which the wire is wound in a closed curve as a whole, once the one end of the spring 6 is opened and inserted into the first spring fixing part 33, the user manipulates it in reverse. Do not fall before you do. This is a different aspect from the second spring fixing part 42 formed in the first noise plate 4. The second spring fixing part 42 is the same as having a circular through hole, but a slit 43 is formed in the through hole. Therefore, the other end of the spring 6 forming the closed curve is caught simply by inserting it into the interior through the slit 43, and once caught, the elasticity of the spring 6 continues to act. If the spring 6 is not pulled out, the spring 6 will not fall out of the second spring fixing part 42.

This action is to move the spring (6) to the first spring fixing portion 33 when moving the fixing assembly 10, so that there is no fear of losing the spring (6) during movement, crossbar When fastening the fixing assembly 10 to (1), the operator should pull the other end of the spring 6 so that the other end is inserted through the slit 43 so as to easily fix the work convenience. To gain the benefits of

In order to allow the first noise plate 4 and the second noise plate 5 to be fastened in a state where the soft friction member 7 is mounted inside the first noise plate 4, the first friction plate 7 is coupled to the first noise plate 4. A first fastening piece 44 and a first screw insertion hole 45 are formed at an end of the noise plate 4, and a second fastening piece 53 and a second screw are formed at an end of the second noise plate 5. Insertion hole 55 is formed. Here, a burr is formed in the second screw insertion hole 55 by a specific processing method such as a deep drawing-and therefore, the second screw insertion hole 55 is formed by the burr. ) Will be easily understood to form the structure of the protrusion projecting rearward from the second fastening piece (53). Threads are formed on the inner surface of the bur by tapping. The first screw insertion hole 45 has a screw insertion hole larger than the screw portion of the bolt.

Therefore, in the state where the soft friction member 7 is seated on the inner surface of the first noise plate 4, the worker pulls the second noise plate 5 toward the first noise plate 4. The screw may be inserted into the first screw insertion hole 45 and the bolt may be turned while the tail portion of the screw is inserted into the second screw insertion hole 55. By this operation, the worker can fasten the screw without fastening a separate nut to the bolt to fix the first noise plate 4 and the second noise plate 5 to each other.

In addition, as described above, a bending part 52 is formed in the second noise plate 5, and the crossbar 1 is formed by at least two portions of the second noise plate 5 by the bending part 52. It can be fixed by the strong pressing force of. Of course, the pressing force of the second noise plate 5 acts as a coupling force between the soft friction member 7 and the crosspiece 1.

Further, cutouts 41 and 51 are formed in the noise plates 4 and 5 so that the noise plates 4 and 5 are hinged shafts when the noise plates 4 and 5 are rotated. 21) and other members.

On the other hand, as a characteristic feature of the present invention, the first noise plate 4 and the soft friction member 7 are provided in an arc shape having a cross section of more than half of a semicircle, unlike the cited references. Therefore, the soft friction member 7 may hold the crossbar 1 to hold and support the crossbar 1, and the first noise plate 4 may include the soft friction member 7 in the crossbar 1. It is possible to apply a strong frictional force to the contact surface of the soft friction member 7 and the crosspiece 1 more strongly by the pressing force to hold the pressure as a whole.

Such a configuration eliminates the need for a member such as a bolt commonly inserted in the crossbar 1 and the first noise plate 4, which can be seen in the above-cited documents, and the like, and makes the work more convenient at the time of installation. The strong pressing force of the soft friction member 7 by the first noise plate 4 and the second noise plate 5 is such that the first noise plate 4 is more than the soft friction member 7. Since the soft friction member 7 is limitedly positioned inside the first noise plate 4 because it is provided in an elongated arc shape, it is natural that the effect can be further enhanced.

Furthermore, the first noise plate 4 and the soft friction member 7 can substantially hold the crossbar 1 to support it, thereby eliminating the need for the bolts found in the references. Thus, even when a counter wind pressure is applied to the sign, the sign 9 is not destroyed, and only the movement of rotating the soft friction member 7 and / or the first noise plate 4 is generated. The support device of the can obtain the advantage that is not broken.

4 is a side view illustrating the extension direction of the fixed plate, the first noise plate, and the second noise plate around the hinge.

Referring to Figure 4, it can be observed in more detail the configuration that makes up a feature of the present invention, first, the vertical fixed plate 3, the hinge shaft 21 directly to the lower end of the fixed plate 3 without being spaced apart It can be seen that the sign (9) is directly fixed to the front of the fixed plate (3), by being configured in this way, the sign (9) and other components attached thereto are gravity or wind pressure or impact against the crossbar (1) Since no strong moment is exerted, the stability of the sign support apparatus can be enhanced.

In addition, when viewed from the hinge shaft 21, the first noise plate 4 extends in an arc shape toward the stationary plate 3. Therefore, the fixed plate 3 and the first noise plate 4 are brought into contact with each other to provide a contact point 39 in the state in which the sign support device of the present invention is installed, and the sign 9 is reversely rotated. By preventing the clockwise rotation relative to the reference, the sign is not rocked by external turbulence and weak wind pressure. Of course, the contact between the fixed plate 3 and the first noise plate 4 can be easily performed by the elastic force by the spring (6).

In addition, when the second noise plate 5 extends from the upper position toward the lower side from the upper position toward the lower side when viewed from the hinge axis 21, the bending portion 52 is used. It is bent upward again. Furthermore, the lower end of the second noise plate 5 is placed above the lower end of the hinge 2. Therefore, when an external impact is applied to the sign 9, the sign is rotated, the rotation angle of the sign can reach up to 90 degrees, the height that can be rotated at the time of the collision of the vehicle is not damaged even higher It is possible to obtain an advantage that can withstand even stronger wind pressure.

5 to 7 is a view illustrating a configuration in which the sign supporting device according to the present invention is installed directly on a sign, with reference to this drawing, the sign supporting device of the present invention is conveniently installed in the sign in more detail. Explain.

Figure 5 is a rear view of the sign according to the invention, Figure 6 is a cross-sectional view of the II 'in FIG. 5 and 6, the rear surface of the triangular sign 9 is provided with two installation guides 8 which are vertically long and long, and in the cross-sectional view of the installation guide, a jaw is formed at the upper end and the head of the bolt is formed inside. An accommodation space to be inserted is formed.

With the above structure, through the openings formed at the upper and lower ends of the installation guide 8, the installation guide in the state where the head of the fastening member exemplified by the bolt 83 is inserted into the receiving space inside the installation guide 8. It slides into the inside of (8) and is inserted. After the bolt 83 is inserted into the installation guide 8 by a predetermined distance, the bolt 83 is caught by the upper locking jaw 81 and the lower locking jaw 82 provided on one side of the installation guide 8. The bolt 83 can no longer be moved and its position is fixed. For example, the locking jaw 81 and 82 may be provided with screws inserted at both sides of the installation guide 8, but is not limited thereto.

At this time, the position where the bolt 83 is stopped by the locking step 81 and 82 is defined in advance according to the shape of the sign, it will vary depending on the shape of the sign. For example, in the case of the triangular sign shown in FIG. 5, the distance H1 from the top of the sign to the height at which the cross is located is about half, whereas in the case of the inverted triangle sign shown in FIG. 7, the top of the sign is shown. The distance (H2) to the height at which the crosspiece is at will be much shorter. This is a preset distance that the sign can be rotated by a certain angle for the proper wind pressure. As such, according to the shape and type of the sign, the position of the bolt is set so that the criterion for rotating the sign by a predetermined angle with respect to the proper wind pressure can be satisfied.

Positioning of such bolts can be clearly understood by the wind pressure test table of the installation structure of the present invention signs shown in Table 1. For reference, Table 1 is a chart measuring the rotation angle of the sign with respect to the wind speed blowing from the front of the sign in the Korea Aerospace Research Institute.

Referring to Table 1, in the case of a square sign, when the distance from the top of the sign to the height of the crosspiece is 368mm, when the wind speed is 30m / s, and the spring (6) constant is 0.1Kg / cm, You can see that it rotates about 40 degrees. And, even if the shape of the sign is different by varying the distance from the top of the sign to the height of the crosspiece is installed-for example, 247 mm in the case of the inverted triangle sign, if the spring constant and the wind speed is the same, the same angle 40 You can see that it rotates about degrees. By changing the installation height of the sign as described above, even if the shape of the sign is different, there is an advantage that can conveniently adjust the rotation angle of the sign.

On the other hand, referring to Table 1, it can be seen that there is no problem that the sign is rotated or dropped by the wind speed blowing from the front of the sign under any wind speed.

Referring to FIG. 5, in the state where the bolt 83 is placed at the position where the locking jaw 81, 82 is mounted, the bolt 83 is also used as the slit 31, 32, 34 of the fixing plate 3. The fixing plate 3 is positioned in such a manner as to be inserted into the nut, and the nut 85 is inserted into the bolt 83 to be firmly fixed thereon. In this case, the supporting device of the sign is completely fixed at the fixed position of the sign. Since the slits 31, 32 and 34 are provided in a shape extending in the lateral direction as shown in the figure, the operator has an advantage that the bolt can be inserted into the slit more conveniently.

Those skilled in the art who understand the spirit of the present invention may further suggest other embodiments that fall within the scope of the same spirit of the present invention.

The bolt 83 can be replaced with any other fastening member, the other fastening member is also provided with a wide head and a narrow body, the head is placed in the receiving space inside the installation guide, the body The part just needs to be drawn out through the jaw of the upper end of the installation guide.

In addition, the above-described embodiment of the present invention has been described taking an example of a sign installed on a crossbar among signs, but the idea of the present invention is naturally applicable to the case of a sign installed on a vertical bar at the corner of the road. This will also be included within the scope of the present invention.

In addition, in the embodiment of the present invention, it is described that a single hinge hinges the fixed plate, the first noise plate and the second noise plate at the same time, but is not limited thereto, and any two members may be formed by a single hinge. The hinge is moved, and the other two members may be hinged by the other hinge, but this will also be included in the spirit of the present invention.

In addition, the installation guide 8 has been described in the case that there are two, but is not limited to this, even if one is presented, there is no problem in the operation.

In addition, the soft friction member is assumed that the whole is provided in a single thickness, but is not limited to this, even if the thickness of the cross-section is provided in a different state, it may be provided only in the form of substantially wrapped around the crosspiece.

In addition, the second noise plate is described as being provided with a bending portion to support the crosspiece at two points, but this is only one of the preferred forms, the second noise plate is to press the first noise plate It is not necessary to push the crossbar in contact with the crossbar. Although the second noise plate is not in contact with the crosspiece, it will be included in the spirit of the present invention.

According to the present invention, the sign is stably supported against strong wind pressure, the structure is simple, the fastening and installation are simple, and the sign can be easily installed without directly processing the crossbar.

In addition, even if the wind pressure is applied to the front and rear of the sign in any direction, it is possible to prevent breakage of the sign.
