Field of the Invention The present invention relates to a device for adjusting the height of a road guide rail, and more particularly to a device for connecting a pair of support members, The present invention relates to a guide rail for a road which is adjustable in height and height so that the entire guide rail can be lifted or lowered even if any one of the pair of rotors is rotated.

In general, a driver of a vehicle traveling on a road must sense the direction of bending of the road on which it is traveling, and make accurate and quick decisions through various guide indicators to enable stable and comfortable operation.

Accordingly, conventionally, a guide rail device has been installed along both edges of the road in which a curved steel plate is bound to a cylinder for the purpose of safe operation and road guidance.

1, a guide groove 5 is formed so as to penetrate from one side to the other side of the guide rail, and a guide rail (not shown) And a guide rail plate (3) having a center, which is formed by drilling the upper and lower portions of which the engaging groove (6) is perforated, and whose cross section has an overall English W (W) And a coupling means 4 for passing through the coupling groove 5 of the rail column 2 and the coupling groove 6 of the guide rail plate 3 so as to be bolted.

In the conventional guide rail device, a predetermined hole is drilled on both edges of the road, and a lower end is inserted to fix the guide rail support 2 upright, and then the concrete is buried in concrete.

The coupling groove 5 formed on the upper portion of the guide rail support 2 fixed as described above and the coupling groove 6 of the guide rail plate 3 protruding from the center and depressing the upper and lower portions are arranged in a straight line And the coupling means 4 such as a bolt and a nut are coupled to complete the guide rail device 1. [

At this time, as described above, the conventional guide rail device 1 in which the concrete is buried and fixed at both edges of the road is aged or broken due to the passage of time, Is automatically reduced.

Thus, when the height of the conventional guide rail device is reduced by the other person, it is not easy for the driver to convey the bend state of the road accurately, which is not only uncomfortable for the driver but also caused the risk of accident.

Accordingly, after the road rehabilitation work is performed, the concrete grinding operation for separating the guide rail supports embedded in concrete on both sides of the existing road is required to increase the conventional guide rails to meet the appropriate field of view of the driver, There has been a problem in that it is inevitable that another guide rail support is fixedly connected to the support by welding and in case of a car accident occurring while driving on the road, There have been many inventions capable of adjusting the height of the guide rail in the recent years.

For example, the height of the guide rail, which is the "guide rail height adjusting device" of Korea Utility Model Registration No. 20-0167927 (November 11, 1999) and Korean Patent Registration No. 10-0463678 (December 16, 2004) And the like. However, all of these conventional techniques have a disadvantage in that the length is formed as a long groove in the connection hole between the strut and the guide rail, so that the operator must individually release the fastening means to adjust the height .

As shown in FIG. 2, the guide rails for height control according to the present invention include a guide portion 100, a guide rail 200, and a height adjusting means 300. At this time, the guide rails 200 are formed in a general plate shape and are provided so as to be connected to the support portions 100 to be described later. The guide rails 200 are provided with a general guide rail 200 formed to be bent, And duplicate description of the detailed description will be omitted in order to clarify the gist of the present invention.

2 and 3, a plurality of the support portions 100 are disposed adjacent to each other on a center line of a road or a road such as between a road and a sidewalk, and the guide rail 200, which will be described later, The lower strut 110 and the upper strut 120. The lower strut 110 and the upper strut 120 are connected to each other.

Here, the lower strut 110 is formed in a columnar shape having a length in the vertical direction, and the lower portion is fixed to the ground by fixing means such as a bolt or the like, and the upper strut 120 is installed so as to be vertically movable . At this time, an insertion hole 111 through which the guide column 121 of the upper strut 120 is inserted is formed on the upper surface of the lower strut 110 so that the upper strut 120 is guided by the guide post 121 So that it can be raised and lowered.

The upper strut 120 has a columnar shape having a length in the vertical direction as a whole and is inserted into the insertion hole 111 at the lower portion thereof and is inserted into the upper strut 120 and the lower strut 120 And a guide rail 200 is fixed to the upper portion of the guide rail 200 by fastening means. At this time, the vertical length of the guide pillar 121 is longer than the vertical length of the insertion hole 111, and is prevented from being detached from the insertion hole 111 at the time of ascending or descending by being wrapped by the rotating body 310, It is preferable that the upper support 120 can be moved up and down according to the rotating direction of the rotating body 310 by screwing with the inner surface of the rotating body 310.

The extension pillar 125 may be further protruded downward from the lower portion of the guide pillar 121. The extension pillar 125 may be raised or lowered so as not to be detached from the auxiliary insertion hole 113 formed in the bottom surface of the insertion hole 111, So that the upper strut 120 and the lower strut 110 can be firmly held by the external impact of the vehicle (see Fig. 6). (See Fig. 6)

In FIGS. 5 and 6, the rotating body 310 is installed and operated in a state of being connected to the lower strut 110. However, in order to facilitate explanation and understanding of each constitution, the upper side will be shown.

Here, the diameter of the extending pillars 125 is preferably 2/3 (two-thirds) or more of the diameter of the guide pillars 121, which is highly desirable in view of strength.

When the extension pillars 125 are provided, it is quite natural that the length of the rotary pillars 310 should be equal to the lengths of the guide pillars 121 and the extension pillars 125.

The height adjusting means 300 includes a rotating body 310, a slide preventing member 320 and a band 330 for lifting and lowering the upper support 120 so that the height of the guide rail 200 can be adjusted. .

When the band 330 rotates any one of the pair of rotating bodies 310, It is possible to rotate the rotating body 310 without slipping. At this time, a ring-shaped rubber material or a synthetic rubber material is used as the anti-skid member 320, and if necessary, embossing formed on the outer surface of the anti-skid member 320 is protruded to maximize the anti-skid effect.

The band 330 is formed to have a band shape as a whole and the through holes 331 inserted into the protrusions 311 protruding from the outer surface of the rotating body 310 are formed to have equal intervals. At this time, the band 330 is connected to at least one pair of rotators 310 so that when the one rotator 310 is rotated, the remaining rotator 310 rotates as well so that the guide rails 200 are lifted It is desirable to make it possible.

It should be noted that the band 330 may be made of a rubber material or an iron plate having excellent elasticity, but may be used as a chain or the like to be fitted to the protrusion 311 if necessary.

As shown in FIGS. 4 and 5, the guide rail for height adjustment according to the present invention having the above-described structure is different from the conventional one in that a pair of guide rails 200, The band 330 is connected to the rotating body 310 which is screwed to the upper strut 120 so that the band 330 is connected to the rotating body 310 of the pair of rotating bodies 310 It is possible to raise and lower the entire guide rail 200 even if any one of them is rotated.

The specific embodiments of the present invention have been described above. It is to be understood, however, that the spirit and scope of the invention are not limited to these specific embodiments, but that various changes and modifications may be made without departing from the spirit of the invention, If you are a person, you will understand.
