Description

Partially replaceable guide rail with cushioning roller {PARTIALLY REPLACEABLE GUIDE RAIL HAVING ROLLERS FOR SHOCK-ABSORBING}

The present invention relates to a guide rail for mitigating the impact generated on the road, and more particularly, to a guide rail having a buffer roller for suppressing the flow of through holes and capable of partially replacing a vertical bar in an installed state.

Guide rails are usually installed on the side of the road or at the center of the road, preventing the pedestrians from entering the road or preventing the vehicle from moving out of the roadway or moving to the opposite lane. In addition, the guide rail serves to reduce heavy traffic accidents by mitigating the impact in an urgent situation when the driving vehicle is off the road. Conventional guide rails have been implemented in a form in which a plurality of horizontal bars are usually supported by vertical bars fixed to the ground using an iron plate or stainless steel. Existing guide rails are made of steel plate or stainless steel, so when the vehicle is impacted while driving away from the road, it is not only crushed or damaged without absorbing most of the impact, but also impacts the vehicle and causes a large traffic accident. It can also be a cause.

Recently, in order to overcome the problems of the above-described guide rail using a steel plate or stainless steel, research on a guide rail having a roller for mitigating an applied impact is being actively conducted, and the trend is being put into practical use. to be. Korean Patent Laid-Open Publication No. 2000-30887 for 'Road Shock Absorber' discloses a guide rail provided with a buffer roller, which will be described with reference to FIG. 1.

Referring to Figure 1, the conventional guide rail (1) between the upper plate (2) and the lower plate (3) fixed to the holding rod (10) embedded in the ground by the U bolt 12, while being installed oppositely, It has a structure which fastens the shaft rod into which the buffer roller 8 is inserted. When the vehicle collides with the conventional guide rail 1 shown in FIG. 1, the shock absorbing roller 8 rotates about the shaft, or the main body of the shock absorbing roller 8 is crushed to absorb impact energy. Relax In the case of the conventional guide rail (1) shown in Figure 1, in order to repair this in case of partial breakage of the buffer roller (8), after separating the shaft bar fastened from the upper plate (2) and the lower plate (3), Replace the damaged buffer roller (8) in the separated shaft rod with the normal buffer roller (8) and insert it into the shaft rod, and install the shaft rod with the buffer roller (8) is inserted into the upper plate (2) and the lower plate (3) Since it has to be concluded between, there is a problem that a lot of manpower, time and cost in maintenance.

In a guide rail using a buffer roller for practical use, the buffer ruler is made of urethane foam or plastic. Guide rails using buffer rollers made of foamed urethane are shown in FIGS. 2A and 2B. Buffer rollers made of foamed urethane have a problem that aging occurs quickly when urethane is exposed to sunlight, and frequently suffers from a problem. As described above, a lot of manpower, time, and cost are required to replace the buffer roller. There is a problem that occurs. 3A and 3B, in the case of a buffer roller made of plastic and a guide rail using the same, the aesthetic appearance is extremely poor when broken by a vehicle, and some buffer rollers are damaged as described above. If it is, there is a problem that a lot of manpower, time and cost to replace it.

A specific object of the present invention is a partially replaceable guide rail having a cushioning roller that can be easily maintained by partial replacement of a vertical bar when a portion of the buffering roller is broken while the buffering roller is installed. To provide.

Another object of the present invention is to provide a partially replaceable guide rail having a buffer roller for preventing the flow of the up and down of the buffer roller by forming a rib inside the buffer roller to suppress the flow of the through-holes.

It is still another object of the present invention to provide a partially replaceable guide rail having a buffer roller that can absorb shock more efficiently by implementing a buffer roller with ethylene-vinyl acetate (EVA).

In order to achieve the above object, according to an aspect of the present invention, a guide rail having a buffer roller and a replaceable part, comprising: an upper horizontal bar and a lower horizontal bar fixed to a support by fixing means; And at least one vertical bar disposed between the upper horizontal bar and the lower horizontal bar, wherein the at least one vertical bar is provided with a through hole forming pipe at a center of two main bodies which are injected and coalesced, and the through hole is formed. It has at least one buffer roller including a rib formed to suppress the flow of the pipe for pipe, wherein the vertical bar includes a central axis in which the upper fitting portion and the lower fitting portion is formed at both ends in the shape of a cylindrical rod, A first insertion hole into which the upper fitting portion is inserted is formed in the upper horizontal bar, and a second insertion hole into which the lower fitting portion is inserted is formed in the lower horizontal bar, and at least one of the upper fitting portion and the lower fitting portion is alternately inserted. And an at least one of the corresponding first insertion hole and the second insertion hole are alternate insertion holes. The mouth portion may be provided as a buffer roller part replaceable guide rail, characterized in that provided for the free insertion and ejection or the alternating insertion hole, that is not the insertion and ejection to the alternating insertion hole.

According to the present invention, the following effects can be expected.

According to the present invention, in the case where some of the buffer rollers are damaged in the state where the buffer rollers are installed, a partially replaceable guide rail having a buffer roller that can be easily maintained by partial replacement of the vertical bar is provided. Can provide.

In addition, according to the present invention, by providing a rib inside the buffer roller to suppress the flow of the through-holes, it is possible to provide a partially replaceable guide rail having a buffer roller for preventing the vertical flow of the buffer roller.

In addition, according to the present invention, it is possible to provide a partially replaceable guide rail having a cushioning roller that can absorb shock more efficiently by implementing a cushioning roller with EVA.
