Description

The invention relates to railway transport, and in particular to a device for the evacuation of passengers with limited ability to independently move from the emergency exit window of the car in the event of an emergency in the tunnel and on land sections.

A well-known fire escape ladder (RU 92334, class A62B 1/00, publ. March 20, 2010), including a device for moving people and attachment points in its upper and lower parts. The device for moving people is made in the form of a canvas, in the lower part contains installation fixing fixing nodes, while the mounting nodes are removable. The canvas for moving people is made with a width of 700 to 2000 mm. The length of the canvas is from 2000 to 15000 mm and depends on the height of the window opening. The canvas is made of a material that provides sufficient glide. The canvas is made in the form of a canopy, with tension elements installed along the long sides. The mount of the upper part is made in the form of a loop and a carbine. The lower attachment is made in the form of a loop, a brake device and a carabiner, while the brake device includes a tension rope mounted on a loop and a brake element connected to the carabiner.

This device is intended for evacuation during emergencies only for healthy people who can independently fix the equipment in the window opening, as well as independently go down the canvas. However, for people with disabilities, this device is not acceptable and not reliable.

A device for evacuating people is known (RU 168596, class A62B 1/20, published 09.02.2017), containing guides attached inside the car to the wall on the sides of the window. Movable crossbar is installed on the guides. The end of the stairs is pivotally connected to the crossbar. The staircase consists of segments in the form of plates having a U-shaped section. The plates are movably interconnected by means of spikes and grooves for the spikes, the spikes of one plate being placed in the grooves of the adjacent plate. At the end of each groove there is a cutout for fixing the corresponding spike. The ladder is folded according to the principle of a telescope, when the last plate is pushed into the penultimate plate, then both plates are pushed into the third from the end of the plate, etc.

However, this device is also intended for emergency evacuation from railway wagons only of healthy and adult people and is not intended for independent evacuation of people with disabilities.

Closest to the invention relates to a device for evacuating people (RU 172372, class A62B 99/00, publ. 07/05/2017) containing an air mattress that is attached at one end to a casing filled with compressed gas. The casing is in communication with the mattress using a nozzle with a valve. The casing is equipped with grips for fixing on the table or on the window of the car. A belt is provided for fixing the mattress to the casing.

However, this device does not provide quick and safe independent evacuation of passengers with disabilities in case of emergency.

The technical problem of the claimed invention is the development of a device for the emergency evacuation of passengers with disabilities from railway cars.

The technical result of the invention is the provision of independent, quick and safe evacuation of passengers with disabilities in case of emergency.

The posed problem and the indicated technical result are achieved by the fact that the device for the independent evacuation of passengers with disabilities from railway cars includes a storage casing in which a mat is placed associated with a gas filling canister. According to the invention, a telescopic frame is additionally installed in the storage casing with the possibility of its movement along the vertical guides of the carriages to the emergency exit using two gas springs mounted on the side walls of the casing. The telescopic frame consists of a fixed and movable frame, with the possibility of tipping it outside the car, which is connected to the mat from the inside, and from the outside to a capsule connected to the sleeve.

The device is preferably installed under the opening of the car window.

An internal spiral is sewn into the sleeve, which in the deployed position is oriented at an angle of inclination to the horizon from 35 to 50º, while the length of the sleeve with the spiral can be from 2.5 to 6 meters.

To fix the telescopic frame in the storage casing, the vertical guides of the carriage are equipped with a spring rod installed in the hole formed between the side wall of the storage casing and the vertical guide of the carriage.

On the outside of the vertical carriage guide there is an unlocking handle associated with the cable.

It is advisable to equip the gas canister associated with the mat with a cord, pulling the gas from the can into the mat for the process of straightening it.

Supporting handles are fixed on the fixed frame of the telescopic frame for independent pulling of the evacuee.

The frames of the telescopic frame are fixed in the storage casing with the help of a loop and a clamp.

The presence of a telescopic frame in the storage casing allows the movable frame to be deployed outside the car without human assistance, and the presence of two gas springs and vertical carriage guides mounted on the side walls of the casing allows the telescopic frame to quickly move to the window opening.

The presence of a fixed frame at the telescopic frame provides the possibility of stable and reliable retention of all equipment for the evacuation of a passenger in the window opening and allows reliable and unhindered acceleration of independent evacuation of a passenger with limited mobility, without the help of unauthorized people or with minimal help, as support handles are mounted on the fixed frame for pulling up the passenger.

The presence of a movable frame, which has the ability to tilt the car outside, allows using the capsules and sleeves with a spiral attached to it to provide free and safe descent from the car to the platform or ground.

An inflatable mat accelerates the process of deploying an external frame without human assistance.

A spring rod installed in the hole formed between the side wall of the storage casing and the vertical guide of the carriage provides vertical movement of the structure and its fixation at the window level of the passenger car when the device is activated in case of emergency.

Fastening the inflatable mat and sleeve with a spiral on a telescopic frame, consisting of a fixed frame and a movable frame with the possibility of tipping and moving the sleeve with a spiral in the radial direction, minimizes the time and effort to bring the structure into working position in case of emergency and ensure quick and safe the evacuation of a disabled passenger.

The presence of the unlocking handle associated with the cable helps to remove the fastener from the loop, and provides a quick reduction of the device to its working position when triggered.

The spiral angle of 35 to 50 ° in the expanded form allows you to quickly and safely overcome the height difference between the window opening of the passenger car and the ground.

The connection of the gas canister with the cord provides instant gas filling of the mat with a minimum of effort with the help of a cord, which, in case of emergency, can be pulled by a passenger with limited mobility.

Fixing in the casing of the storage of the outer frame and the inner movable frame of the telescopic frame with a loop and fastener eliminates the possibility of spontaneous operation in the presence of vibrations due to the movement of the train.

The invention is illustrated by drawings, where in FIG. 1 shows a general view of the device in the folded position, FIG. 2 is a general view of an expanded device of a passenger ready for evacuation, FIG. 3 is a general view of a sleeve with a spiral.

A device for the independent evacuation of passengers with disabilities from railway cars is installed under the opening of window 1 and includes a storage casing 2, in which a mat 3 is placed, connected with a canister 4 of gas filling. A telescopic frame 5 is installed in the storage casing 2 with the possibility of its movement along the vertical guides 6 of the carriages to the opening of the window 1 using two gas springs 7 mounted on the side walls of the storage casing 2. The telescopic frame 5 is equipped with a fixed frame 8 and a movable frame 9, which has the possibility of tipping over to the outside of the car. On the inside, the movable frame 9 is connected with the mat 3, and on the outside, with the capsule 10 connected to the sleeve 11 with a length of 2.5 to 6 meters into which the spiral 12 is sewn at an angle of inclination from 35 to 50 ° to the horizontal.

An internal spiral is sewn into the sleeve, which is oriented in the deployed position, while the length of the sleeve with the spiral can be from 2.5 to 6 meters.

To fix the telescopic frame 5 in the storage casing 2, the vertical guides 6 of the carriage are provided with a spring rod 13. On the outside of the vertical guide 6 of the carriage there is an opening 14 for fixing the spring rod 13 when the unlocking handle 15 is connected, connected with the cable 16.

The gas canister 4 is equipped with a cord 17. On the fixed frame 8 of the telescopic frame 5 fixed support handles 18 for independent pulling evacuated. The frames 8 and 9 of the telescopic frame 5 are fixed in the storage casing 2 using the loop 19 and the clamp 20.

A device for the independent evacuation of passengers with disabilities in an emergency works as follows.

In case of emergency, a passenger with disabilities, independently or with the help of other persons, breaks the glass of window 1 with a hammer (not shown in Fig.), Removes the cover of storage casing 2 to freely prepare the device for deployment and allow access to the handle 15 of the unlocking mechanism. When you press the handle 15, the cable 16 of the unlocking mechanism releases the loop 19 of the telescopic frame 5 from the bracket 20. Due to the two gas springs 7 and the guides 6 of the carriages (such as Rollon or their analogues), the telescopic frame 5 moves upward. From the storage casing 2 the mat 3, the sleeve 11 with the spiral 12 and the capsule 10 are moved and fixed in the window 1. The fixation is due to the actuation of the spring rod 13 located on the movable frame 9 of the telescopic frame 5, as it rises along the vertical guides 6 of the carriages. When the hole 14 coincides with the spring rod 13, it straightens under the action of the spring and occupies a position inside the hole 14 of the storage casing 2. This procedure can take from 5 to 30 seconds. Next, the movable frame 9 with an inflatable mat 3 and a sleeve 11 with a spiral 12 tilts independently into the opening of the window 1, resting on its lower edge, preventing further movement of the device in the radial direction. The evacuee pulls on the cord 17 attached to the canister 4 of gas, due to which the process of straightening the mat 3 is activated by filling it with gas from the can 4. When inflated, the mat 3 overturns part of the movable frame 9 with sleeve 11 and with the capsule 10, resulting in the sleeve 11 is lowered down to contact with the ground or apron, and straightens, providing a free opening to prepare for the descent of the passenger. Then the passenger is pulled up, holding on to the specially provided support arms 18 on the fixed frame 8 (or moving by rolling or crawling), and through the inflatable mat 3, head or feet forward, through the capsule 10 it enters the sleeve 11 with a spiral 12, which ensures uniform and safe evacuation passenger from the wagon.

The device for self-evacuation of passengers from the window opening is simple and accessible during its operation, which allows people with disabilities to use it independently without outside help. Accompanying bedridden passengers can evacuate patients with minimal time and physical costs.

The present invention is not limited to the description provided and can be expanded within the scope of the claims, for example, its location relative to the window opening may also be in another convenient place for use. A specialized emergency exit can be provided and, depending on its location, the device, with minimal modification within the stated formula, can be installed either from below, from the side or from above.

Currently, a device for the independent evacuation of passengers with disabilities from railway cars is at the prototype stage.
