Description

[0001] SHOCKPROOF TYPE END FACILITY FOR ROAD [0002]

The present invention relates to a shock absorbing road end facility, and more particularly, to a shock absorbing road end facility capable of absorbing an impact while being compressed so as to reduce the volume of the end facility in the event of a collision, And more particularly, to an impact absorbing road end facility capable of effectively absorbing impacts.

Conventional median separators and guard rails are constructed such that panel members bent in a wave form are provided parallel to the direction of the lane with a shock absorber interposed on both sides of the column vertically installed on the ground, There is provided an end finishing base for covering the sharp end portions of both side panel members.

1 to 7, a shock absorbing road end facility according to a first embodiment of the present invention includes a panel member 50 connected to a guard rail and provided with a first buffer 52, A support member 10 supporting the member 50 and standing upright on the surface of the panel member 50 and a panel member 50 having an impact on the panel member 50 to compress the volume of the panel member 50, And a second buffer 80 connected to the second buffer 80.

The present embodiment is a facility that is installed at a center separator provided at the center of the road or at an end of a guard rail provided at the edge of the road to absorb shock when a collision occurs. When a collision occurs, the first buffer 52 And the second cushioning portion 80 absorbs the impact over the second time, so that it is possible to reduce personal injury.

The first cushioning portion 52 includes an installation frame 52a provided at an end of the panel member 50 and forming a curved surface to form an internal space and an elastic member 52b installed inside the installation frame 52a Therefore, when the vehicle collides with the end of the panel member 50, the mounting frame 52a is deformed and the elastic member 52b is compressed to primarily absorb shock.

When the impact due to the vehicle collision is not completely absorbed, the second buffer 80 functions to slide the panel members 50 so that the panel members 50 are overlapped with each other, .

Therefore, when a vehicle collision occurs in the end facility according to the present embodiment, since the shock absorption is performed by the first buffer 52 and the second buffer 80, the damage to the person is effectively reduced .

Here, since the primary shock absorption and the secondary shock absorption can be generated with a slight time difference, they can be regarded as almost simultaneous actions, which can be easily perceived by a person skilled in the art recognizing the technical composition of the present invention A detailed description of the time difference between the primary shock absorption and the secondary shock absorption will be omitted.

Since the panel member 50 of the present embodiment is continuously connected so that a plurality of the panel members 50 can flow, two or more panel members 50 are slidably connected to the end portions of the guard rails to form an end facility.

Accordingly, when a collision occurs at the end of the panel member 50, the plurality of panel members 50 are compressed so as to overlap with each other, so that shock absorption can be performed.

The support member 10 includes a first pillar 12 disposed on the ground surface, a second pillar 14 inserted into the first pillar 12, a second pillar 14 connected to the second pillar 14 in a fluid- And a bracket 30 on which a bracket 32 to which the bracket 50 is fixed is mounted.

Since the first pillar 12 is inserted and fixed on the ground as described above, the first pillar 112 installed on the existing guard rail is cut to form the second pillar 12 having a relatively small diameter inside the first pillar 12, It is possible to easily install the end facility according to the present invention and the process of removing the existing first column 112 and the process of installing the new first column 12 are omitted, And the time and cost required for replacement can be reduced.

When the support member 30 is connected to the upper end of the second column 14 inserted into the first column 12 so that the panel member 50 is compressed so as to overlap with each other, The support member 30 supporting the support member 50 is caused to flow together with the panel member 50.

Therefore, it is possible to reduce the amount of impact applied to the vehicle by the conventional support 30 fixed to the ground at the time of a vehicle collision.

The bracket 32 includes a main body 34 provided on the second pillar 14 and extension portions 32b and 32c extended from the main body 34 and supported by the panel member 50, Is inserted into a hole formed in the main body (34), and the support base (30) is connected to the main body (34) by bolting or welding.

The extension portion 32b extends laterally from the main body 34 so that the extension portions 32b and 32c and the panel member 50 are welded to each other so that the panel member 50 can be connected to both ends of the main body 34 So that the pair of panel members 50 can be connected to each other so as to maintain a space around the bracket 32.

The main body 34 includes a first main body 34a for supporting the panel main body 150 constituting the guard rail and a panel member 50 connected to the panel main body 150 forming the guard rail in a fluid- And a second body 34b that is narrower than the first body 34a.

Since the panel body 150 constituting the conventional guard rail is installed in the relatively large first body 34a, the guard rail is formed to be wider than the end facilities, and the first body 34a and the second body 34b A plurality of panel members 50 are compressed to the guard rail side in the event of a collision and a plurality of panel members 50 are connected to each other And slides along the bent portion 50a to induce the compression operation of the panel member 50 to be gradually stopped.

Here, the widths of the first and second main bodies 34a and 34b can be variously changed according to the structure of the guard rail, and can be easily changed by those skilled in the art, Therefore, detailed drawings and explanations according to other embodiments will be omitted.

Since the present embodiment further includes the variable portion 70 that connects the second post 14 to the first post 12 in a fluid-tight manner, when the panel member 50 is compressed so as to overlap with each other in the event of a collision Since the support base 30 flows by the action of the variable portion 70, the compression operation of the panel member 50 is smoothly performed.

The variable portion 70 includes a flow connection portion 72 for slidingly connecting the second column 14 to the first column portion 12 so as to be assembled and a second column 14 slidable by the flow connection portion 72, And a flow restraining portion 74 for restricting the sliding movement of the valve body.

The flow connection portion 72 connects the second column 14 and the support member 30 in a sliding manner so that when the second column 14 and the support member 30 are coupled to each other, Can be installed by inserting the lower end of the support base 30 in a sliding manner so that the support base 30 can be installed by omitting a separate bolt operation or welding operation.

When the collision occurs, the lower end of the support bar 30 slides from the upper end of the second column 14 and is separated, so that the panel member 50 and the support bar 30 are not fixed, 50 are compressed so as to overlap with each other, so that shock absorption is performed.

At this time, since the support base 30 is completely separated from the paper surface, the movement of the support base 30 by the action of the flow restraining portion 74 is prevented at a higher speed than necessary, .

Therefore, when a high-speed vehicle collides with the panel member 50, the panel member 50 is compressed more quickly than necessary, so that even after the compression of the panel member 50 is completed, the shock absorption is not completed, .

The flow connection portion 72 includes a connection panel 72a provided on the second column 14 and a sliding groove portion 72b provided on the support base 30 to slidably surround the connection panel 72a.

The sliding groove portion 72b is curved in a 'C' shape at both ends to enclose both end portions of the connection panel 72a so as to be slidably coupled to the connection panel 72a. Accordingly, the sliding groove portion 72b is inserted into the connection panel 72a can be inserted to connect the support base 30 and the second pillar 14 without a separate fastening operation.

The curved surface portion 72c is formed at the end of the sliding groove portion 72b so that the curved surface portion 72c is formed when the sliding groove portion 72b is separated from the connection panel 72a and slides along the ground, The sliding groove portion 72b can be prevented from colliding with the ground, and the second pillar 14 is pushed rearward to perform the buffering action.

The flow restraining portion 74 includes a fixing pin 74a provided on the ground surface, a wire 74b connected to the fixing pin 74a and extending through the support base 30, (74b) provided on the wire (74b) so as to restrain the sliding member (74b) from slipping through the support base (30).

The fixing pin 74a is provided at the end of the panel member 50, that is, the surface opposite to the first buffer 52, so that when the vehicle collision occurs, the fixing pin 74a is wound in the opposite direction to the direction in which the panel member 50 is compressed And the engagement ring 74c provided on the wire 74b interferes with the support base 30 so that the wire 74b is prevented from passing along the hole formed in the support base 30 do.

The second cushioning portion 80 includes a sliding hole portion 82 formed in the panel member 50 and a fastening member 82 fastened to another panel member 50 continuously inserted in the sliding hole portion 82, And a curved portion 86 formed in a wavy shape so that the fastening member 84 rubs while being moved when the fastening member 84 is slid when the sliding hole portion 82 is bent into a curved line.

The coupling member 84 is slid along the sliding hole portion 82 so that the plurality of panel members 50 are compressed so as to overlap with each other and the coupling member 84 is slid along the sliding hole portion 82 The panel member 50 is compressed in a wavy manner while passing through the continuous curved portion 86, thereby reducing the compression speed of the panel member 50.

Therefore, since the speed at which the panel member 50 is compressed is prevented from being increased more than necessary, the panel member 50 is gradually compressed at the time of a high-speed vehicle collision, .

The first cushioning portion 52 and the cushioning portion 10 are connected to the support portion 10 disposed adjacent to the first cushioning portion 52 of the shock absorbing road end facility according to the second embodiment of the present invention A fixed base 88 is provided.

Therefore, when the low-speed vehicle is hit, the shock absorption is performed by the compression of the elastic member 52b. At this time, the interval between the first cushioning portion 52 and the cushioning portion 10 is maintained It is possible to prevent the impact from being transmitted to the panel member 50. When the impact is increased, the fixing member 88 is deformed and shock absorption can be performed.

The protrusion 50b formed by bending the end portion of the panel member 50 to protrude in the lateral direction is formed on the end portion of the panel member 50 according to the present embodiment. Therefore, when the panel member 50 is compressed to overlap, It is possible to smoothly start the operation of sliding the plurality of panel members 50 to overlap with each other as the member 84 is inserted into the protrusion 50b.

Operation of the shock absorbing road end facility according to an embodiment of the present invention will be described below.
