DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accident prevention device capable of coping with a sudden dive accident on a railway.

[0002]

2. Description of the Related Art In recent years, jumping accidents frequently occur on railways, and not only the misfortune of the accident person, but once an accident occurs, it takes a lot of time to recover the accident, and many users are inconvenienced. . On the other hand, in order to cope with these railway accidents, means for activating an emergency brake such as an ATS device has been adopted. However, this ATS device can be effectively operated when trains are close to each other in a closed section. Operation can hardly be expected for an accident requiring urgency such as a dive accident.

[0003] In addition, the emergency brake has been enacted so that vehicles running on conventional lines can be stopped within 600 m after the brake is applied. I can't resist a dive accident. Therefore, at present, almost no effective means has been found for this dive accident.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned situation, and has developed a device which is excellent in shock mitigation and quick operation, and has been devised so as to cope with a sudden dive accident. Things.

According to the present invention, there is provided a train accident prevention apparatus for a train, in which a shock absorber provided with a front bag and a bottom bag is stored in a folded state at each end of the train in the traveling direction, and the bag is stored in the bag body. An inflator that generates inflation gas is connected via the connected connecting pipe, and an elevating mechanism for lowering the shock absorber to near the ground is provided.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An accident prevention apparatus according to the present invention comprises a shock absorber 10 arranged in front of a leading car of a train,
And a lifting mechanism 30 for lowering the shock absorber to near the ground.

As shown in FIGS. 1 and 3, the shock absorber 10 is located in front of the front end of the train in the train traveling direction, and is a front bag 11 for receiving the same or slightly narrower victim from the front. Distribute. It is preferable that a plate 11a for supporting the bag is provided on the back surface of the front bag 11, but this is not necessary when the shape of the bag can be maintained by the gas pressure at the time of inflation.
In addition, a bottom bag 12 that supports the subject from the bottom is arranged on the lower surface of the front bag 11 so as to be connected to the front bag. At this time, it is preferable to attach the plate body 12a for the same reason as in the case of the front bag. And, between the front plate bag 1 and the bottom bag 12,
A side bag 13, which protects the subject from the left and right sides if necessary;
13, the side bags 13, 13 may be inflated by gas filling like the front bag 11 and the bottom bag 12, but since the impact in the lateral direction is small, there is no normal expansion. It may be a cloth body. Reference numeral 14 denotes a guide plate for preventing the subject from getting into the gap between the train body and the ground and guiding the subject into the bottom bag.

The front bag 11, the bottom bag 12, and the side bag 1
Each of the members 3 and 13 is foldable by taking in and out a gas, which will be described later. Normally, the gas is drawn out so as to be folded and stored in a certain case (see FIGS. 2 and 3). The bag may be made of any material as long as it has flexibility and toughness as a bag, but is generally a coated nylon material.

Each of the front bag 11 and the bottom bag 12 (side bags 13 and 13 if necessary) is provided with a connecting pipe for communicating with an inflator 20 to be described later for each room, and is inflated. Allow each bag to be filled with gas instantaneously.

[0010] An inflator 20 for generating gas for inflating and expanding the bag body is provided at the end of the connection hole. As an example of the inflator, as shown in FIG. 4, it is provided with an igniting agent 21 and a gas generating agent 22, ignites a small amount of explosive by an electric signal, ignites a propellant by the heat of combustion, and discharges sodium azide. Nitrogen gas generated when the propellant as the main component undergoes a decomposition reaction is sent to the bag.

A switch mechanism for transmitting an electric signal for ignition is connected to the inflator 20. The switch mechanism includes a manual switch mechanism and an automatic input mechanism using computer software. First, the manual switch mechanism is an input switch that the driver who senses the occurrence of the accident artificially presses immediately before the accident, and is operated by a skilled driver based on past experience and keen attention. It is a high means.

On the other hand, the automatic input mechanism, for example, arranges video equipment at the head of a train, sends image data from the video to an image processing system of a computer, and performs pattern recognition or the like on a train track or in the vicinity thereof. And recognizes a human body, an animal, and other obstacles existing in the system, and automatically switches on under a certain condition based on the recognition. The image may use image information emitted from a satellite in the future.

[0013] The switch mechanism may be either one of the above, but it is ideally provided with both.
The one caused by human being is excellent in urgency and agility, but there is a risk of oversight, while the one based on the sensor mechanism has no disadvantage, but there is a disadvantage that the ambiguity remains in determining whether it is an accident, A mutually complementary relationship is desirable.

[0014] Further, it is preferable that a communication pipe connected to an air compressor is also provided in the bag body in order to compensate for the gas once inflated with the passage of time. The start switch mechanism of the inflator described later is wired via a timer so that the bag is kept inflated.

Next, the shock absorbing mechanism 10 is provided with an elevating mechanism which keeps the height of the bottom bag 12 as close to the ground as possible during normal operation while maintaining the proper height which does not hinder the running of the vehicle. 30 is attached. 5 and 6, a specific example of the lifting mechanism 30 is shown in FIG. 5 and FIG.
A suspension rope 32 connected to the plate body 11a of No. 0 is further disposed, a constant pulley 33 is disposed above the suspension rope 32, and a constant pulley 34 is disposed below the constant distance by a fixed distance. A cylinder 35 that reciprocates in the vertical direction is disposed in the portion. The cylinder 35 may be a hydraulic cylinder, but is an air cylinder in order to expect quick response to the cylinder, and further allows the inflation gas generated in the inflator 20 to flow into the cylinder chamber, and lowers the piston rod by the pressure. It is desirable to adopt a mode of descending to

Further, the front bag 11, the bottom bag 12, the side bag 1
It is desirable to apply a pressure-sensitive adhesive exhibiting a relatively strong adhesive force to the surfaces of 3, 13 and to put an exfoliating paper on the interface between the bags. That is, after the cushioning effect is exerted by the bag, the resilience acts due to its elasticity, and there is a possibility that the human body is rebounded, and the bonding force between the clothes and the bag is reduced by the viscosity of the adhesive. It is intended to be activated and to be fastened in a bag for a while. The release paper is in a folded state to prevent adhesion between the bags.

The apparatus of the present invention is newly installed on a train that is already in operation, and is installed in advance on a train that is newly installed in the future.

Next, the operation of the embodiment of the present invention will be described.
First, if a suspicious person appears in the direction of travel of the train while the train is running, it is the same as in the past to sound a horn and start slow driving. Activate the brake and input the inflator switch at the same time. At this time, there are two types of input methods, manual input manually and automatic input linked to a computer. Activates the inflator by one of the inputs. At this time, the artificial input is a highly effective means of exhibiting the experience of a skilled person and sharp attention, and the one using a computer image processing system is near the train track by pattern recognition etc. It is a reliable means that can recognize existing human bodies, animals, and other obstacles and does not make human error, but both have advantages and disadvantages. Therefore,
It is desirable to use both, but at this time, if either one is input, the circuit configuration is such that both are connected by an OR circuit so that the inflator is always activated. The reason is that even if one of them is wrong, it is tolerated and ensure the prevention of accidents.

Then, when the switch of the inflator is turned on, the explosive is ignited, and the propellant containing sodium azide as a main component causes a decomposition reaction to generate nitrogen gas by the heat of combustion. At the same time, slightly before that, the switch of the elevating mechanism 30 is input, the piston rod of the cylinder 35 is extended, the suspension rope 32 is suspended via the pulleys 33 and 34, and the shock absorber connected to this. Lower the entire 10 down. At this time, the cylinder 35 of the elevating mechanism 30 may be operated by an air compressor mounted on the train. However, when a part of the expanded gas is sent to the cylinder 35, the descent is instantaneously completed simultaneously with the operation of the inflator 20. Therefore, the speed is excellent.
As a result, it is possible to make the shock absorber 10 face as close to the ground as possible.

Next, gas having an inflating force generated in the inflator 20 is supplied to the front bag 11 and the bottom bag 1 through the connection holes.
2 (side bags 13, 13 if necessary) are sent instantly to each room of each bag. Then, each of the bags folded in the storage box 31 is expanded at the same time as the expansion, and the bottom bag 12 is placed in the front bag 1.
1 about 90 degrees apart to form a bottom surface, side bag 13,
13 unfolds on both sides. When the bags continue to inflate, each bag is filled with gas, fills a certain thickness, and exerts a cushioning effect against collision by elasticity of the gas.

If an accident is encountered, the guide plate 1
4 scoops up the subject, the front bag 11 receives the body from the front, cushions the impact due to the buffering action, the bottom bag 12 receives the drop from the front and keeps it in that position, and the side bags 13, 13 are the side bags. When it is bounced back, it is received and maintained in the bottom bag 12. In this way, even if there is a considerable impact due to the collision, the air elasticity of each bag reduces the destructive force and at least functions so as not to lose human life. In addition, since the body of the accident person is fastened to the shock absorbing device formed by each bag, it is possible to minimize the damage to the body.

At this time, if the surface of the bag is coated with an adhesive, the bonding between the highly adhesive clothing and the bag is promoted by viscousness. , Instantaneously resisting the repulsive force and further increasing the protection.

Further, when a communication pipe connected to an air compressor is provided in the bag, the inflated state of the bag is maintained even if the gas once expanded expands with time.

[0024]

According to the present invention based on the above configuration and operation,
The shock absorber is activated instantly from the switch input, and it has excellent urgency that can respond to any sudden jumping accident, and the front bag and the bottom bag filled with gas against the impact due to the collision are accidents It captures the subject and reliably exerts a buffering action. Therefore, it is a very effective solution to a railway dive accident, for which no countermeasure has been taken in the past, and is an excellent invention that contributes to rescue of human lives.
