The guide rails 10 are formed in the shape of a rectangular shaft and fixed horizontally on a concrete foundation provided on the ground or the ground. The guide rail 10 may be formed as a railway rail.

The guide member 20 is movably fixed in a state of being fitted to the shaft which is the guide rail 10 and can be moved along the guide rail 10 by external pressure.

The guide member 20 may be formed in a shape of "?" That is, the guide member 20 is composed of an upper plate slidable on the upper surface of the guide rail 10 and a side plate projecting downward from both sides of the upper plate and positioned on both sides of the guide rail 10. And screw tabs 21 may be formed on the upper and side plates of the guide member 20, respectively. In addition, at the end of the side plate, a latching jaw 22 is formed which is engaged with the lower portions of both sides of the guide rail 10.

The frame 30 includes an outer frame part 31 formed of a rectangular plate or bent in the shape of a "? "To be fixed to the guide member 20, a frame 30 fixed to the inner side of the outer frame part 31, Plate 32 as shown in Fig.

Since the outer frame part 31 is fixed to the guide member 20, it can be moved along the guide rail 10 together with the guide member 20. The shock absorber 50 may be fixed to the frame plate 32.

The frame 30 may be formed with a roof member 33 covering the upper portion thereof. The roof member 33 may be formed of a plate material whose central portion is convex upward so as to guide foreign substances such as snow, rain, or dust to the outside to prevent contamination of the frame 30 or the shock absorbing member 50 . Each of the roof members 33 is composed of a plurality of roof members 33, and each of the roof members 33 can be fixed to each of the frames 30 in a state where one ends thereof are overlapped with each other.

Also, the finally positioned frame 30 can be fixed so as not to move on the ground or concrete foundation. Therefore, when the other frame 30 is moved to the fixed frame 30, the impact absorbing member 50 can be contracted.

The guard rail 40 is formed of a rectangular plate, and has a curved shape along the longitudinal direction, so that the curved shape of the guard rail 40 is deformed by the collision of the vehicle, thereby relieving the shock. The guard rails 40 are installed on both sides of the frame 30 in a state where one end and the other end of the guard rail 40 are horizontally overlapped with each other and are overlapped with each other at the time of collision of the vehicle, ≪ / RTI >

The honeycomb unit 51 can be formed by connecting hexagonal holes in a hexahedron or by connecting hexagonal pipes in series so that the impact due to collision of the vehicle can be minimized by contracting by external pressure due to collision of the vehicle. Further, the number of the honeycomb units 51 can be selected and connected, so that the overall length of the honeycomb units 51 can be adjusted.

The honeycomb fixing part 52 is formed of a plate material bent in an L shape or a U shape so that both sides of the honeycomb part 51 are fixedly caulked and fixed to the frame 30 or the guard rail 40 by bolting do.

The honeycomb fixing part 52 is formed in a box shape in which an inner space is opened to the upper part and is made of an iron plate or a synthetic resin so as to be broken or folded by external pressure and fixed to the guard rail 40 by bolting.

The honeycomb unit 51 is formed of a hexagonal tube body and the honeycomb protrusions 53 are formed on the outer side of the three surfaces and the honeycomb protrusions 53 are inserted outside the three surfaces opposite to the three surfaces on which the honeycomb protrusions 53 are formed The honeycomb fixing portion 52 is formed with a fixing groove 55 into which the honeycomb protrusion 53 of the honeycomb portion 51 is inserted and fixed and inserted into the honeycomb groove 54 A fixing protrusion 56 to be fixed can be formed.

Since the honeycomb protrusions 53 can be inserted and fixed in the honeycomb grooves 54 so that the hexagonal tubular bodies as the honeycomb units 51 are connected successively, the connection operation of the honeycomb units 51 can be easily and quickly performed, The collision of the vehicle can be minimized while being continuously folded.

The honeycomb protrusions 53 are connected to the honeycomb grooves 54 and the hexagonal bodies of the honeycomb 51 are connected to each other to maintain the block shape.

10 to 11, the honeycomb units 51 of the shock absorbing member 50 are formed with honeycomb wings 51a which are respectively protruded outward from the corners symmetrical to each other, and the ends of one honeycomb wing 51a A honeycomb protrusion 53 may be formed and a honeycomb groove 54 may be formed at an end of another honeycomb blade 51a.

The honeycomb wings 51a may be formed to have a half length in one side of the honeycomb unit 51. That is, when the honeycomb protrusions 53 are coupled to the honeycomb grooves 54, when the honeycomb wings 51a are connected in a line, the honeycomb protrusions 53 have the same length as one side of the honeycomb unit 51. Accordingly, a hexagonal space having the same shape as that of the honeycomb unit 51 can be formed between the honeycomb units 51 as the honeycomb wings 51a are connected in a line, thereby providing the same effect as the honeycomb unit 51, There is an advantage that the number of the units 51 can be reduced. Of course, if the length of the honeycomb wings 51a is increased, a rectangular hexagonal space can be formed.

The honeycomb fixing part 52 is formed in a box shape in which the inner space in which the honeycomb unit 51 is accommodated is opened to one side, and an engaging projection 57 and an engaging groove 58 corresponding to the upper and lower parts are formed on the upper part and the lower part, respectively And a connecting piece 59 through which the engaging projections 57 penetrate to both sides.

Here, the honeycomb fixing part 52 formed in a box shape can be fixed to the frame 30 or the guard rail 40 by bolting.

Accordingly, the honeycomb fixing portions 52 are stacked, and the combined protrusions 57 and the coupling grooves 58 are combined, so that the stacked state of the honeycomb fixing portions 52 can be firmly maintained.

The honeycomb fixing parts 52 may be arranged side by side when the respective coupling protrusions 57 formed on the honeycomb fixing parts 52 are fixed through the connection pieces 59 on both sides.

In this way, the honeycomb fixing parts 52 can be arranged vertically and vertically, as well as aligned back and forth and side by side.

The box-shaped honeycomb fixing portion 52 may also be provided with the fixing grooves 55 and fixing protrusions 56 corresponding to the honeycomb protrusions 53 and the honeycomb grooves 54 described above.

The speed reducing member 60 may be composed of a bolt that is screwed to the screw tab 21 of the guide member 20 and rubbed against the guide rail 10 at an end thereof. The head of the bolt, which is the speed reducing member 60, may be formed in a square or hexagonal shape.

The guide member 20 moves along the guide rail 10 along the guide rail 10 as the bolt which is the speed reducing member 60 screwed to the screw tab 21 of the guide member 20 is contacted and rubbed against the guide rail 10, Lt; / RTI > As a result, when the vehicle collides with the guide member 20, the impact due to the collision can be alleviated because the guide member 20 is moved at a low speed.

12 to 14, the guide member 20 includes a friction member 90 which is frictionally engaged with the guide rail 10 while moving together with the guide member 20.

The friction member 90 includes a friction pad 91 formed to have a predetermined width and a pad fixing portion 92 for fixing the friction pad 91 in a state of being fastened to the guide member 20.

The friction pad 91 may be formed by a metal plate and may be knurled to increase frictional force on the lower surface contacting the guide rail 10. The friction pad 91 may be formed with a groove into which the bolt, the pad fixing portion 92, is inserted. That is, when the bolt is inserted into the groove, the friction pad 91 is not separated from the pad fixing portion 92 during the movement of the guide member 20.

The pad fixing portion 92 may be composed of a bolt that is screwed to the screw tab 21 formed on the guide member 20 and fixes the friction pad 91.

The friction pad 91 rubs against the guide rail 10 when the guide member 20 is moved along the guide rail 10 together with the frame 30 due to the impact of the vehicle, Can be reduced. Since the engaging protrusions 22 formed on the end portions of the side plates of the guide member 20 are engaged with the lower portions of both sides of the guide rail 10 so that the friction pads 91 are continuously rubbed without being separated from the guide rails 10 .

The friction member 90 includes a pressing portion 93 which presses the friction pad 91 while being fixed to the pad fixing portion 92. The pad pressing portion 93 is composed of a spring washer which is fixed in a state where the pad fixing portion 92 is penetrated and is elastically changed by an external pressure.

Therefore, when the friction pad 91 is rubbed against the guide rail 10 and the lower surface is worn out, the pad 93 is elastically deformed while being supported by the guide member 20 to press the friction pad 91, The pad 91 can be continuously rubbed against the guide rail 10 while being worn. Whereby the moving speed of the guide member 20 can be reduced.

In addition, the present invention may include a pressing portion 70 for pressing the bolt as the speed reducing member 60 in accordance with the movement of the guide member 20, as shown in FIGS. 15 to 20. The pressing portion 70 includes a pinion 71 coupled to a head of a bolt that is a speed reducing member 60 and a rack 72 having a pinion 71 provided in parallel with the guide rail 10 in a state in which the pinion 71 is engaged. ).

When the guide member 20 is moved along the guide rail 10 by the collision of the vehicle, the pinion 71 engaged with the rack gear 72 is rotated, so that the speed reducing member 60 can be tightly pressed against the guide rail 10 while being rotated. At this time, even if the guide member 20 is moved at a high speed and the bolt as the speed reducing member 60 is worn, the pinion 71 is continuously rotated, so that the bolt, which is the speed reducing member 60, As shown in Fig. As a result, frictional force is constantly applied to the guide rail 10, so that the guide member 20 can be moved at a low speed. Further, even when the bolt as the speed reducing member 60 rubs against the guide rail 10 due to the movement of the guide member 20, the pinion 71 can be rubbed against the rack gear 72, (20) can be moved at low speed.

It is also preferable that the radial dimension 72 is formed to have a width larger than that of the pinion 71. That is, the pinion 71 presses the bolt as the speed reducing member 60, and moves to the outside of the rack gear 72 as it is.

If the pressing portion 70 is provided on both sides of the guide member 20, the frictional force can be doubled, and the collided vehicle can be stopped more slowly.

The pinion 71 may be formed with a square or hexagonal hole such that the head of the bolt, which is the speed reducing member 60, is inserted and fixed. Therefore, the bolt which is the speed reducing member 60 can be inserted and fixed. Therefore, when the pinion 71 is rotated, the head of the bolt which is the speed reducing member 60 is restrained by the pinion 71, so that the bolt can be rotated together.

Here, the head of the bolt, which is the speed reducing member 60, can be integrally joined by the engagement with the pin or the welding in the state where the head of the bolt is inserted into the pinion 71. [ At this time, when the pin is engaged by the pin, the bolt which is the speed reducing member 60 can be separated from the pinion 71, and maintenance can be performed.

The present invention also includes a decelerating member 80 for decelerating the speed of the guide member 20 moving along the guide rail 10 as shown in Figs.

The deceleration member 80 includes a deceleration wire 81 having one end connected to the frame 30 and a deceleration reel 81 wound around the other end of the deceleration wire 81 so as to be spaced apart from the guide rail 10 A deceleration pressing portion 83 for pressing the outer peripheral surface of the deceleration wire 81 pulled by the movement of the frame 30 or for pressing the outer peripheral surface of the deceleration reel 82 released by the pulling of the deceleration wire 81, . ≪ / RTI >

One end of the deceleration wire 81 may be fitted with a hook to be fixed to the frame 30.

The decelerating reel 82 is rotatably incorporated in a case provided on the ground or concrete foundation.

The deceleration pressing portion 83 includes a pressing case 84 in which the inner space is opened at one end, an elastic body 85 built in the pressing case 84 to provide an elastic force, And a deceleration pad 86 for pressing the deceleration wire 81 and the deceleration reel 82 by the elastic force of the elastic body 85.

The deceleration pressing portion 83 may be a spring that can decelerate the rotation speed of the deceleration reel 82. [

Therefore, when the frame 30 moves along the guide rail 10 together with the guide member 20 due to the collision of the vehicle, the deceleration wire 81 is pulled. At this time, the deceleration reel 82 is rotated at a low speed by the deceleration pressing portion 83 or the deceleration wire 81 is pulled at a low speed. As a result, the frame 30 is moved at low speed, so that the impact caused by the collision of the vehicle can be gradually reduced.

As described above, the present invention can absorb shocks while mitigating impacts due to collision when colliding with a vehicle in a state of being installed at front and end facilities such as a median separator, and can minimize the breakage of the vehicle and damage to the protection facilities, It is a very useful invention that can be widely applied to the end of a median separator such as a highway, a national highway, and a local road because it can protect passengers from accidents.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the above description is intended to be illustrative, and not restrictive, and that the scope of the present invention will be defined by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the equivalent concept are to be construed as being included within the scope of the present invention.
