It protrudes in front of the leading vehicle of the railway train.

According to the present invention, the following effects can be achieved.
(A) When a person or automobile that is a target of an accident appears unexpectedly and a collision occurs, the impact on the person or automobile can be reduced as much as possible, and damage to the host vehicle can be reduced.
(B) By providing shock absorbers for preventing direct hits at the connecting portions of the vehicles on the railroad train, the impact at that location can be reduced.

  (C) Reasonable impact can be received by the shock absorber for preventing direct hit by the extension of the spiral spring band.

  The shock absorber for direct hit prevention of the railroad train of the present invention is a plurality of locations excluding the operation device at the time of abnormality arranged in the driver's seat of the leading vehicle of the railroad train and the front window portion of the driver's seat of the leading vehicle of the railroad train. A helical spring band that is housed and locked in a normally contracted state, and the helical spring band is unlocked when the operating device is operated in the event of an abnormality, The spring belt body is extended and protrudes in front of the leading vehicle of the railway train.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a perspective view of a front portion of a leading vehicle of a railroad train showing a first reference example of the present invention, and FIG. 2 is a side cross-sectional view of a main part and a fluid of a shock absorber for preventing a direct hit at the front portion of the leading vehicle of the railroad train. The perspective view of a bag and FIG. 3 are the principal part top sectional views of the buffer device for the direct hit prevention.
In this figure, 1 is the front part of the leading vehicle of the railroad train, 2 is the window part of the driver's seat, 3 is the projecting part protruding below the window part 2, 3 'is the projecting part in the evacuation state, and 4 is the projecting part A fluid bag 4A is provided in the part 3, an orifice formed in the fluid bag 4 is opened by applying a predetermined pressure to the fluid bag 4, and a receiving plate 5 is disposed at the rear of the fluid bag 4. , 6 is a driving panel, 7 is an operation switch which is arranged on the driving panel 6 and is operated in the event of an abnormality, 8 is a driver, and 9 is a wheel.

  In this way, since the projecting portion 3 is arranged in the front part 1 of the leading vehicle of the railroad train and the fluid bag 4 is equipped there, there is a train and a car ahead, and this vehicle is there. In the case of a collision, the driver 8 operates the operation switch 7 at the time of abnormality, and slides the protruding portion 3 of the front portion 1 of the leading vehicle by a driving device (not shown), so that the protruding portion in the evacuated state As 3 ', the container of the fluid bag 4 is exposed, the shock absorber for direct hitting is set, and a sudden brake is applied.

  Therefore, even if a railroad train or automobile existing ahead collides with the front part 1 of the leading vehicle of the railroad train, the energy at the time of the collision is effectively absorbed by the fluid bag 4 provided in the projecting portion 3, and the front The impact of trains and cars that collide with each other can be reduced. The fluid bag 4 can be, for example, an oil bag containing oil that is less compressible than air. Moreover, it can replace with this oil bag and a water bag can also be used.

  In addition, as shown in FIG. 2B, when an orifice 4A that is opened by applying a predetermined pressure from the outside is provided, that is, when a hole is provided to discharge fluid when absorbing an impact. By properly discharging the fluid, it is possible to expect a damper effect in which the resistance when the fluid passes through the orifice 4A absorbs impact energy. Thus, when the orifice 4A is provided and the fluid is discharged to the outside, it is effective to use a water bag using water as the fluid in consideration of environmental problems.

In addition, when the projecting portion is configured by a member having lower rigidity than other portions, the fluid bag can be configured to be incorporated in the vehicle body. Further, a part of the fluid bag may be always exposed.
Moreover, as shown in FIG.1 and FIG.2, it is made the shape which rounded the low position so that a person and a motor vehicle may not be pinched | interposed between the lower part of a leading vehicle, and a rail.

FIG. 4 is a perspective view for explaining a shock absorber for preventing a direct hit at a connecting portion between subsequent vehicles of a railway vehicle according to a second reference example of the present invention, and FIG. 5 is a perspective view of an essential part thereof.
In these drawings, 11 is a leading vehicle of a railroad train, 12 is a following vehicle, 13 is a further succeeding vehicle, 14 is an oil bag equipped at the rear of the leading vehicle 11, and 15 is arranged at the front of the following vehicle 12. 16 is an oil bag disposed at the rear portion of the following vehicle 12, and 17 is an oil bag disposed at the front portion of the further succeeding vehicle 13. For example, as shown in FIG. 5, the leading vehicle 11 and the succeeding vehicle 12 of the railway train are connected by a coupler 18 </ b> A, and a through passage 18 is formed.

  Therefore, as shown in FIG. 4, in the case where the leading vehicle 21 of the railroad train going backwards against the leading vehicle 11 of the railroad train collides, as shown in the first reference example, the oil of the leading vehicle 11 of the railroad train The collision is buffered by the oil bag 22 of the leading vehicle 21 of the railway train that runs in reverse to the bag 19, and for example, the oil bags 14 and 15 are provided at the rear portion of the leading vehicle 11 and the front portion of the following vehicle 12. For this reason, also in this connection part, a collision is buffered mutually. The collision is similarly buffered at the connecting portion between the other vehicles.

  FIG. 6 is a perspective view of the front part of the leading vehicle of the railroad train showing a third reference example of the present invention, FIG. 7 is a perspective view of the main part of the shock absorber for preventing direct hits at the front of the leading vehicle of the railroad train, and FIG. Is a perspective view showing a modification of the shock absorber for direct hitting, FIG. 9 is a schematic configuration diagram of a drive system for the shock preventing device for direct hit, FIG. 10 is a diagram showing a shock absorber with a pressure sensor, and FIG. It is a figure which shows the shock absorber with a film | membrane which reacts and is damaged.

As shown in FIG. 6, the buffer material A for preventing direct hit is normally mounted on the front surface 33 of the lower part of the window 32 of the driver's seat at the front of the leading vehicle 31 of the railway train, and is always reduced. .
Although not shown, like the first reference example, an operation switch 7 that is operated in the event of an abnormality is disposed in the driver's seat, and when the operation switch 7 is operated as shown in FIG. When the control device 38 is operated, the high-pressure fluid from the high-pressure fluid source 39 acts on the shock-absorbing material A for direct hit and expands from the front surface 33 below the window 32 of the leading vehicle 31, for example, as shown in FIG. The box body 35 in which the pocket portion 34 is formed can be formed. When a person or animal collides, it can be accommodated in the pocket portion 34 in an emergency evacuation manner.

Further, as shown in FIG. 8, the box body 35 may be formed with two layers of an oil bag 36 at the base and an air bag 37 on the front surface thereof.
In this way, by constituting two layers, it is possible to share the role by impact load. This reference example is suitable for interpersonal use.
Moreover, solids such as granules may be put in place of fluid and air, which is effective for both humans and objectives.

  Furthermore, as shown in FIG. 10, when the pressure sensor 37A is provided in the air bag 37 of the box body 35 and a predetermined pressure is applied to the air bag 37 from the outside (for example, a person or an object collides). The valve control device 38 is actuated to send air to the vacuum vessel 37B and reduce the pressure slightly to reduce the initial maximum impact force at the time of collision. The compressed fluid source 39 is an air source for forming the air bag 37 of the box body 35.

In addition, as shown in FIG. 11, the air bag 37 of the box body 35 can communicate with the vacuum container 37C, and a predetermined pressure is applied to the air bag 37 from the outside to the communication portion between the air bag 37 and the vacuum container 37C. When the pressure is reduced (for example, when a person or an object collides), the pressure-reducing film 37D can be provided.
In FIGS. 10 and 11, it goes without saying that fluid such as oil can be used instead of air.

FIG. 12 is a perspective view of the front portion of the leading vehicle of the railroad train showing the first embodiment of the present invention, FIG. 13 is a perspective view showing a state in which the shock absorber for direct hit of the present invention is operated, and FIG. It is a schematic block diagram of the drive system of the buffer device for a vehicle.
Normally, as shown in FIG. 12, a spiral spring band 43 as a reduced elastic member is housed and locked at a plurality of locations excluding the window 42 of the driver's seat of the leading vehicle 41 of the railway train. .

Therefore, when the operation switch 7 is operated at the time of abnormality, as shown in FIG. 13, the lock of the spiral spring band 43 as an elastic member is released and extended to protrude in front of the leading vehicle of the railway train. A spiral spring band elastic member 44 is obtained.
Here, a drive system of the shock absorber for preventing direct hit will be described with reference to FIG.
A cap 44-1 is attached to the tip of the spiral spring band (elastic member) 44, and a lock piece 44-2 that engages with a lock claw is formed on the cap 44-1. Yes.

On the other hand, a lock wheel 47 having a lock claw 48 formed on the inner side and teeth formed on the outer periphery is disposed on the fixed side, and this lock wheel 47 is driven by an operation switch 7 that is operated in an abnormal state. It is configured to be driven by a pinion gear 46 connected to the motor 45.
Therefore, normally, since the lock piece 44-2 of the cap 44-1 at the tip of the spiral spring belt 44 and the lock claw 48 of the lock wheel 47 are engaged, the shock absorber for direct hit prevention is locked. However, when the driver operates the operation switch 7 in the event of an abnormality, the pinion gear 46 is rotated by driving the motor 45, the lock wheel 47 is rotated, and the lock pawl 48 is attached to the tip of the spiral spring belt body 44. When the cap 44-1 is detached from the lock piece 44-2, the helical spring band 44 which is stored in a reduced size pops out vigorously with a spring force as shown in FIG. Is set.

  The spiral spring band 44 is first lightly received at the tip of a collision with a train or automobile, and the reaction force of the spring increases as the helical spring band 44 is gradually compressed. By effectively stopping the trains and cars that collide, it is possible to effectively absorb the energy at the time of the collision. Moreover, the impact at the time of the collision with the own train can be reduced accordingly. In other words, it is a reasonable direct hit prevention shock absorber.

FIG. 15 is a perspective view of the front portion of the leading vehicle of the railroad train showing the second embodiment of the present invention, FIG. 16 is a perspective view showing a state in which the shock absorber for preventing direct hit of the present invention is operated, and FIG. It is a schematic block diagram of the drive system of the buffer device for prevention.
In these drawings, normally, as shown in FIG. 15, a telescope type elastic assembly device 54 as a reduced elastic member 53 is provided at a plurality of locations excluding the window portion 52 of the driver's seat of the leading vehicle 51 of the railway train. Is stored.

Therefore, when the operation switch 7 is operated at the time of abnormality, as shown in FIG. 17, the valve control device 55 is operated to operate the electromagnetic operation type valve 57, and a high-pressure fluid (for example, air) is supplied from the compressed fluid source 56. , And compressed air is sent to the cylindrical portion 58, and as shown in FIG. 16, the telescope-type elastic assembly device 54 is extended to project in front of the leading vehicle of the railway train.
Therefore, normally, the cap 54-1 at the tip of the telescope type elastic assembly device 54 is only seen as the head vehicle of the railway train, but is extended when the telescope type elastic assembly device 54 is extended. Since the cylindrical member 54-3 is filled with fluid, the impact force can be absorbed effectively. In this case, since the cylindrical member 54-3 needs to receive an impact force, the cylindrical member 54-3 needs to have appropriate rigidity.

FIG. 18 is a perspective view of the front portion of the leading vehicle of the railroad train showing the fourth reference example of the present invention, and FIG. 19 is a perspective view showing a state in which the shock absorber for direct hit of the present invention is housed (not activated). FIG. 20 is a schematic configuration diagram showing a state in which the shock preventing device for preventing direct hit is operated.
In these figures, lids 63 are arranged at a plurality of locations excluding the window 62 of the driver's seat of the leading vehicle 61 of the railroad train, and a buffer member 64 is wound and stored inside the lid 63.

Therefore, when an operation switch (not shown) in the event of an abnormality is operated, as shown in FIG. 20, the buffer member 64 is filled with a compressed fluid, and the lid 63 is automatically opened to extend and the internal fluid is liquefied. Or give it elasticity by making it gel. Naturally, the outer skin of the buffer member 64 can be formed of a structurally strong member (such as a fire hose member).
By comprising in this way, a buffer member with good storage property can be constituted.

Needless to say, if the shock absorber for preventing direct hits is arranged behind the rear end of the train, it is also effective against obstacles colliding from behind.
Further, as the buffer member of the reference example, rubber that absorbs shock, a shock absorbing silicon member, or the like may be used.
In addition, the operation device in the event of an abnormality is linked to an emergency sudden braking performed by the driver, or is automatically activated when it is detected that the approaching obstacle is approaching and the distance and speed are abnormal. You may make it comprise.

As described above, according to the present invention, it is possible to provide a railway vehicle that is gentle against obstacles.
In addition, this invention is not limited to the said Example, A various deformation | transformation is possible based on the meaning of this invention, and they are not excluded from the scope of the present invention.

  The shock absorber for preventing direct hit of a railway train according to the present invention can be used as a shock absorber for preventing direct hit of a railway train capable of receiving a reasonable impact.
