The present invention relates to a shock absorbing device for a vehicle using waste tires, and more particularly, to prevent the support guide from being damaged by allowing the front side plate to be easily moved forward when a vehicle crashes, and without anchoring the ground. Not only to securely lock into the groove of the ladder, but also relates to a vehicle impact shock absorbing device for preventing secondary collision due to the reverse movement of the ladder by preventing the contracted waste tire member itself to recover even if the diastolic machine is broken.

As is well known, traffic accidents are increasing due to the rapid expansion of traffic volume due to the expansion of economic scale and income increase, and the speed of road traffic due to the improvement of vehicle performance. In addition, there is an urgent need for the maintenance of roadside facilities and the installation of protective structures proven through rigorous research, especially in the case of traffic accidents, especially vehicle accidents.

The most representative of these protective structures is a guard rail and a road vehicle impact shock absorber installed in front of the guard rail.

The guardrails are installed on both sides of the road or on the centerline of the road to divide the roadway's vehicle width, protecting passengers and vehicles from roadside hazards and gently guiding their direction when the vehicle leaves the road. It is used to prevent the following accidents and to prevent vehicle occupants and vehicle damage, and the road vehicle collision shock prevention device is installed in front of the guard rail or concrete structure to absorb the impact when the vehicle traveling forward collides. .

However, the above-described conventional vehicle impact shock absorbing device is simply installed in the front of the guard rail or concrete structure by tying together 5 to 10 tires together, it was pointed out as a problem that causes more safety accidents. .

That is, the tires are installed without simply being fixed in front of the guardrail or concrete structure, which is caused by a problem that the tires are thrown out and interfere with the safe operation of other vehicles when a vehicle collision occurs, and also the tires are guardrail or concrete structure. Even if it is fixed to the tire material does not gradually generate a cushioning effect, the vehicle is thrown out, there is a problem that the risk of collision with other vehicles.

Instead of such a tire or concrete structure, a vehicle impact shock absorber 1 as shown in FIG. 1 has been invented, which includes a plurality of bellows 3 that expand and expand between the diaphragms 2. The field 3 is always kept inflated by a spring (not shown), and the guard rails 4 are provided on both sides to be movable.

Therefore, the vehicle impact shock absorber 1 shown in FIG. 1 is installed on the road yard, and if the car collides in the direction of the arrow of FIG. 1, the bellows 3 is left to right as shown in FIG. In this case, the collision of the vehicle is absorbed by the momentary narrowing.

However, the above-described vehicle impact shock absorber 1 can mitigate the impact in the case of a large vehicle, but in the case of a small passenger car, the bellows 3 which contracted momentarily at the time of collision is affected by the spring force. By expanding again, there was a problem that a fatal adverse effect on the body or human life.

Therefore, the present applicant is to prevent the vehicle crash shock absorber to be inflated again in the event of a vehicle collision to prevent secondary accidental damage to the human accident and the vehicle body winder for preventing vehicle collision (Korean Utility Model Registration No.357788) ) Has been devised, as shown in FIGS.

As can be seen from these figures, the utility model devise of the above is a vehicle collision shock absorbing device (1) for maintaining the tension in the longitudinal direction and the vehicle collision impact absorbing device (1) in the event of a vehicle collision ) Is wound in the longitudinal direction to quickly wind the wire (10) stretched by the contraction, the vehicle impact impact absorbing device (1) includes a winding means 20 so as not to expand again.

When there is a crash of the vehicle in the direction of the arrow in the left portion as shown in Figure 3, the vehicle impact shock absorber 1 is contracted in the direction of the arrow, in this case the tension wire 10 is stretched by the contracted length Therefore, at this time, the winding means 20 operates instantaneously to quickly wind the sagging wire 10 so that the vehicle impact shock absorbing device 1 is kept in a contracted state, and thus the vehicle collision due to the collision of the vehicle. When the accident treatment is completed while the shock absorber 1 is contracted, it is necessary to expand the contracted vehicle impact shock absorber 1 to its original shape. In this case, the winding means 20 is operated manually. By restoring the vehicle impact shock absorber (1) to the original, and repairing and repairing the broken parts are to be reinstalled.

However, as shown in Figs. 4 and 5, the vehicle impact shock absorbing device 1 includes a plurality of bellows 3 and springs 5, so the manufacturing cost is very expensive. Since a number of bolts 7 are respectively installed to fix the bellows 3, there is a problem that the number of working hours increases.

On the other hand, the present applicant has been registered as a vehicle crash shock absorbing device as Utility Model Registration No. 367001 and 376121, these designs are to adhere to a number of waste tires to be contracted in the collision of the vehicle to absorb the shock Figure 1 And to solve the disadvantages of the conventional vehicle impact shock absorbing device shown in Figure 3, described with reference to Figures 6 to 11 as follows.

As can be seen in Figure 6, the vehicle impact shock absorbing device 30 of the utility model devised a plurality of waste tires 41 are bonded to each other in a laminated manner, but the outer tires of the waste tires 41 waste tires A cushioning waste tire member 40 having an opening 41a through which air enters and contracts when the field 41 is compressed and expanded; A plurality of diaphragms 50 to which the waste tire member 40 is fixed and moving in the compression direction of the waste tire member 40 when the vehicle collides with the waste tire member 40; An expansion preventing means (60) for preventing the artificial expansion of the compressed compressed tire member (40) during the collision of the vehicle.

Here, the expansion blocking means 60 is installed in the longitudinal direction of the waste tire member 40, as shown in Figures 7 and 8 and the ladder 61 is formed with a plurality of engaging grooves (61a); A locking anchor installed in the lower portion of the diaphragm 50 that directly collides with the vehicle among the diaphragms 50 to be selectively caught in the engaging grooves 61a so that the compressed compressed tire member 40 is not artificially expanded during a collision. 62; And a release device 64 for operating the wire 63 to manually relax the compressed waste tire member 40.

As can be seen in FIG. 8, the interval of the groove 61a formed in the ladder 61 of the expansion blocking means 60 is narrowed toward the diastolic 64 so that the anchor 62 is securely locked in the event of a collision. (61a).

As shown in FIG. 9, the anchor 62 is elastically operated by the spring 62a so that the operating range is adjusted by the bolt 62b and the nut 62c. A support guide 65 for allowing the 50 to move along the rail 70 is fixed by the bolt 67a and the nut 67b via the bracket 66a, and the anchor 62 is attached to the spring 62c. It is fixed by the bolt 68a and the nut 68b via the bracket 66b so as to be elastically operated.

Therefore, when the vehicle collides in the direction of the arrow as shown in FIG. 7 in a state where it is installed on the roadway neck as in the state of FIG. 6, the waste tires 41 of the waste tire member 40 are contracted. At the same time as air escapes through the openings 41a of the tire 41, the rounded portion (outer side) of the anchor 62 mounted on the lower portion of the front side plate 50 passes over the inclined portion of the groove 61a. Going through the next groove 61a sequentially, this process is determined by the collision force of the vehicle (see FIGS. 10 and 11).

Therefore, when the vehicle collides and stops, the inner surface of the anchor 62 is caught in the corresponding groove 61a. At this time, the diastolic machine 64 is maintained by the wire 63 so that the ladder 61 is maintained. 40 maintains the contracted state as shown in FIG. 7 to prevent secondary expansion of the waste tire member 40 to protect the vehicle body from damage and human life.

On the other hand, when the collision of the vehicle is completed as shown in Figure 7 when the accident is completed, the tire tire member 40, which had been contracted should be relaxed as shown in Figure 6, in this case, the diastolic machine 64 manually As the air is released through the plurality of holes 41a formed in the waste tire 41 by rotating the wire 63, the waste tire member 40 that has been contracted gradually relaxes. To maintain the initial state.

However, the utility model design shown in FIGS. 6 to 11 has the following problems.

First, there was a problem that the support guide 65 is not moved smoothly on the rail 70 when the front side plate 50 moves forward during a collision of the vehicle,

Secondly, as can be seen in FIG. 10, the anchor 62 is always elastically downward in the groove 61a of the ladder 61 by the spring 62a toward the ground. 61a) was stuck in the ground and could not function as an anchor,

Third, if the diaphragm breaks or breaks down when the vehicle collides, as shown in FIG. 7, the ladder 61 moves instantaneously in the opposite direction of the arrow due to the self-resilience of the waste tire member 40. There was a problem of causing secondary damage to personnel.

Therefore, the present invention can easily move a plurality of diaphragm forward in the event of a vehicle collision to prevent the damage of the support guide, and to ensure that the anchor is securely locked in the groove of the ladder without getting stuck in the ground, It is an object of the present invention to provide a vehicle impact shock absorbing device for preventing secondary collision due to the reverse movement of the ladder by preventing the artificial movement of the ladder to maintain the contracted state of the waste tire member even if the diastolic machine is damaged.

The present invention for achieving the above object is a plurality of waste tires bonded to each other in a laminated manner, but the outer tire of the waste tires and the buffer tire member having an opening having an opening through which air enters during compression and expansion of the waste tires; ; A plurality of diaphragms fixed to the waste tire member and moving in the compression direction of the waste tire member along the rails when the vehicle collides with each other; A ladder mounted between the rails at the bottom of the diaphragm and having a plurality of engaging grooves formed therein; And a vehicle impact shock absorber having a manually operable diaphragm for returning a contracted waste tire member to an initial state after a collision of the vehicle, the apparatus comprising: a collision guider welded to the lower portion of the diaphragm to reduce frictional force with the rails; Rollers for easily moving the diaphragms forward when the vehicle collides with each other; A locking anchor installed in a lower portion of the forefront directly colliding with the vehicle, the locking anchor being elastically operable to selectively catch the locking grooves formed in the ladder so that the compressed waste tire member is not expanded during the collision of the vehicle; Technical features are characterized in that it comprises a stopper for preventing the artificial movement of the ladder to keep the waste tire member is in a contracted state even if the relaxer breaks during vehicle departure.

The anchoring anchor used in the present invention is preferably installed in the lower portion of the front plate directly colliding with the vehicle, but is also installed in one adjacent side plate, that is, both side plates may be generated when the vehicle collides. It is desirable to prevent malfunction of the anchor.

On the other hand, it is preferable that the anchor has a locking surface locked behind the groove of the ladder when the vehicle collides, and an inclined surface to easily ride over the front of the ladder, which is a problem of the anchor as in the prior art, that is, the conventional This solves the problem of the anchor getting into the groove of the ladder during the collision of the vehicle.

And the stopper is fixed to prevent the flow of the ladder before the end of the accident after the crash, it is preferable to fix the separation from the ladder to return the contracted waste tire member to the initial state by operating the diastolic after the end of the accident. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 12 is a perspective view showing a state before a vehicle collision of the vehicle impact shock absorbing device 100 according to the present invention, in which the same reference numerals as in FIG. Description is omitted. The vehicle impact shock absorbing apparatus 100 of the present invention shown in FIG. 12 uses four waste tires 41 each used in the waste tire member 40 as shown in FIG. 18 to efficiently absorb impact during a collision of a vehicle. , 4, 3, 3 bar, which is only for explaining the present invention, the number of the waste tires 41, etc. may of course vary depending on the conditions of the road to be installed.

13 and 14 show an exploded perspective view and an assembled perspective view of the expansion blocking means used in the present invention, which are similar to the conventional one shown in FIG. 9 but differ in anchors and support guides.

As can be seen in FIG. 13, the support guides 110 are fixed to the lower sides of the diaphragms 50 in a manner such as welding, and these support guides 110 are in contact with the upper surfaces of the rails 70. Rollers 120 to reduce the frictional force with the rail 70 is arranged in the shaft hole (110a), each roller 120 is fixed by the C-ring 121 so as not to be separated. Therefore, when the vehicle collides, the diaphragm 50 is easily moved forward due to the roller 120 built in the support guide 110 under the diaphragm 50.

In addition, two anchoring anchors 130 used in the present invention are installed at the bottom of the diaphragm 50, which is a bracket 133 fixed to the diaphragm 50 by the bolt 131 and the nut 132. As shown in FIG. 19, the locking anchor 130 has a locking surface 130a by the spring 135. As shown in FIG. It is located on the lower left side, and its inclined surface 130b is inclined so as to easily ride over the front of the groove 61a of the ladder 61, so that the latch formed on the ladder 61 during the collision of the vehicle as described later. The locking surface 130a is selectively caught by the grooves 61a to elastically operate so that the contracted waste tire member 40 does not expand when the vehicle crashes.

 15 is an exploded perspective view of the main components of the vehicle impact shock absorbing device 100 used in the present invention shown in FIG. 12, in which the same reference numerals as in FIG. 8 denote the same parts. The detailed description is omitted, and only essential parts of the present invention will be described.

The stopper 140 shown in FIG. 15 is for preventing the movement of the ladder 61 so as to keep the waste tire member 40 in a contracted state even when the diastolic machine 64 is broken when the vehicle exits. Before the probation ends, the anchor bolt 141 is fixed to the anchor bolt 141 using a nut 142 to prevent the flow of the ladder 61. In this case, the tip 140a of the stopper 140 supports the end of the ladder 61. It was made.

Therefore, in order to return the contracted waste tire member 40 to its initial state after a vehicle collision, the nut 142 is removed, the stopper 140 is separated from the ladder 61, and the diastolic machine 64 is operated manually. By relaxing the wire 63, the contracted waste tire member 40 was returned to its initial state. And, in Figure 15, the rail 70 is preferably installed in a suitable way, for example, by using a separate anchor bolt on the asphalt, or by removing the asphalt, it is preferable that the concrete can be fixed by a separate bolt or the like. .

FIG. 16 shows that four waste tires 41 are sequentially connected to the diaphragm 50 assembled by FIGS. 13 and 14, and the connection method and the opening 41a of these waste tires 41 are shown. As to the formation of the present invention is disclosed in detail in Korean Utility Model Registration No. 367001 and 376121 issued to the present applicant, detailed description thereof will be omitted.

The operating state of the present invention configured as described above will be described.

As can be seen in FIG. 15, the ladder 61 used in the present invention is located inside the rail 70 for guiding the diaphragm 50, and at one end thereof, the rudder 64a of the wire-operated diaphragm 64 is provided. The wire 63 drawn out from the fixing is fixed and is maintained as shown in FIG.

Therefore, when the vehicle collides in the direction of the arrow in the state of being installed on the roadside neck as shown in Figs. 12 and 17, the waste tire member 40 is contracted as shown in Figs. As shown in the drawing, the air inside the waste tire 40 escapes through the opening 41a and at the same time, the inclined portion 130b of the anchor 130 mounted on the lower portion of the first and second diaphragms 50 from the left side of the drawing. ) Passes through the groove 61a of the ladder 61 and passes sequentially through the next groove 61a. This process is determined by the collision force of the vehicle (see FIGS. 23 and 24).

Accordingly, when the vehicle stops due to a collision, the locking surface 130a of the anchor 130 is caught in the groove 61a, and the waste tire member 40 remains closed as shown in FIGS. 21 and 22. By preventing secondary expansion (artificial expansion after contraction) of the tire member 40 to protect the vehicle body damage and human life.

In addition, the stopper 140 supports the end of the ladder 61 so that the ladder 61 does not move at all in the opposite direction of the collision (the direction in which the waste tire member 40 is intended to expand) even when the diastolic machine 64 is broken. As a result, secondary expansion of the waste tire member 40 can be reliably prevented.

Meanwhile, when the vehicle collides and the device of the present invention is as shown in Figs. 21 and 22, the waste tire member 40, which has been contracted, should be relaxed as shown in Figs. 12 and 17. At this time, the waste tire member 40, which was contracted by gradually releasing the nut 142 and separating the stopper 140 from the ladder 61 and manually releasing the wire 63 by releasing the wire 63, was gradually removed. Is relaxed to maintain its initial state.

Figure 25 shows another embodiment of the expansion blocking means used in the present invention, which is the inner side of the support guide 110 when the diaphragm 50 is advanced during the collision of the vehicle with the upper side of the rail 70 Because it comes in contact with, it is to move forward more smoothly.

That is, the tab hole 110b is formed in the support guide 110, and the wrench bolt 150, the spring 151, and the ball 152 are inserted into the tab hole 110b, and the ball 152 is a rail. Closely engaged with the upper side of the 70, the spring 151 provides a pressing force to the ball 152, the wrench bolt 150 is for adjusting the pressing force of the spring 151.

Accordingly, the support guide 110 is advanced along the rail 70 without being pulled out by the ball 152 being closely engaged with the upper side of the rail 70 by the spring 151 during the vehicle crash.

As described above, the present invention allows the front side plate to be easily moved forward when the vehicle collides to prevent damage to the support guider, and to ensure that the anchor is securely locked to the groove of the ladder without getting stuck in the ground, Is a very useful invention that can effectively prevent the secondary collision due to the reverse movement of the ladder by preventing the retracted waste tire member itself is restored even if the breakage.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto and there may be many variations and modifications within the scope of the following claims.

For example, the number of the waste tires 41 constituting the waste tire member 40 may be more than four or less than four, may vary according to the conditions of the road, and the number of anchors 130 may also vary. The spring 135 for imparting elasticity to the anchor 130 may be provided for each anchor 130, but one spring may be deformed to impart elasticity to two anchors, and the roller 120 may be arranged on the support guider. Of course, rolling means such as bearings can be used instead.
