The known device does not provide fast, reliable and safe evacuation of passengers in case of emergency.

The objective of the claimed utility model is to ensure the safety of the carriage of passengers in subway cars in the event of an emergency.

The technical result when using the utility model is to increase the reliability of the device and ensure fast, reliable and safe evacuation of passengers in case of emergency.

The specified technical result is achieved by the fact that the device for emergency exit from the driver’s cab of the subway car, comprising a door for emergency exit, installed with the possibility of turning up and down in the doorway of the frontal part of the car, a ladder in the form of steps located on the inner surface of the door, traction, elements of the device for fixing the door in the transport position is equipped with a door transformation mechanism located on both sides of the door and made in the form of a spring for smooth movement of the door and two shoulders hinged-lever mechanism, the door is made in the form of a metal frame on which the outer panel is mounted, and the ladder is made of two parts, the first part of which is fixedly mounted on the metal frame of the door closer to its opening, and the second part is made in the form of a stepped block and installed with the possibility of rotation relative to the first part, and in the transport position, the steps of the second part of the ladder are located on the steps of the first part of the ladder.

In addition, the elements of the device for fixing the door in the transport position are installed at a height equal to 3/4 of the door height.

The utility model is illustrated by drawings.

A device for emergency exit from the driver’s cab of a subway car (Fig. 1) includes a door 1 for emergency exit with a window unit 2, mounted with the possibility of up and down rotation in the doorway 3 of the frontal part of the car. The door 1 (figure 2, 3) is made in the form of a metal frame 4, on which the outer panel 5 is made of fiberglass.

Door 1 has two extreme positions: - transport position at which it is located above, i.e. fixed in the doorway 3 cars; operating position at which it is at a certain angle to the level of the rail head, i.e. in an emergency.

On the inner surface of the door 1 is a ladder 6 in the form of steps. The ladder 6 consists of two parts: the first part 7 and the second part, made in the form of a stepped block 8. The first part 7 of the ladder 6 is fixedly mounted on the metal frame 4 of the door 1 closer to its opening 3 and consists of at least three steps 9 of different widths: for example, for the safety of passengers at the exit, the upper step is wider than the rest of the steps. The step block 8 is mounted on the frame 4 with the possibility of rotation relative to the first part 7 of the ladder 6.

In the transport position, the step block 8 is compactly placed inside the frame 4, while the steps of the step block 8 are located on the steps 9 of the first part 7 of the ladder 6. This arrangement of steps provides unobstructed view from the driver's cab.

The step block 8 is equipped with a panel 10 of aluminum, which in the transport position is located inside the driver's cab, and in the working position is located inside the frame 4 of the door 1 to protect the window block 2 from destruction.

In the working position (figure 4), the ladder 6 is located, for example, at an angle of 24 ° to the upper level of the rail head, which ensures the safety of passengers when leaving the ladder 6.

For reliable fixation of the stepped block 8 in the transport and working positions at the ends of the frame 4 there are lock-latches 11, 12 (Figs. 5, 6), one on each of its lateral sides.

To bring the ladder 6 to the working or transport position, a transformation mechanism is provided (Figs. 2, 4) located on both sides of the door 1, made in the form of a spring 13 for smooth movement of the door 1 and the two-armed articulated lever mechanism, the first link 14 of which is made in the form of double parallel plates (Fig.7), and the second rod 15 is made in the form of a rod with an elongated groove 16 at the end from the side of the first rod 14, while the second rod 15 is fixed in the middle of the frame 4 of the door 1.

To fix the door 1 in the doorway 3 in the transport position, the frame 4 contains on both sides the elements of the device for fixing the door, made in the form of plates 17, which are located at a height equal to 3/4 of the height of the door 1. In each plate 17 there is an alternating groove 18 cross-sections for engagement with the tongue 19 of the lock 20 located on the doorway 3 inside the driver’s cab.

The operation of the device is as follows.

In an emergency, the locks 20 are opened from the inside of the driver’s cab, after which they push the door 1 with the ladder 6 out, giving it a slight acceleration. Under its own weight, the door 1 begins to fall to the calculated (at least 24 °) angle of inclination of the ladder 6 to the upper level of the rail head. After moving the ladder 6 down, pull the lock - latch 11, release the step block 8 and turn it until it is fully opened.

Then, in the open position, the step block 8 is fixed with a latch 12. The ladder 6 is securely fixed and ready for passengers to exit.

When moving the door 1 with the ladder 6 to the transport position, the step block 8 is first released from the latch 12, fold it with the first part 7 of the ladder 6 and fixed with the latch 11. Then, with a minimum effort, lift the door 1 into the doorway 3, close and locks 20 locks inside the driver's cab.

If necessary, the process is repeated.
