Description

The proposed utility model (PM) refers to means of rescuing people from transport when the exit is blocked. Designed for emergency evacuation of passengers, mainly from the compartment of a carriage in the event of a fire on the train.

Known kit for emergency evacuation of passengers from the train compartment (see RF patent for PM No. 168783). This kit includes a hammer for breaking a compartment window, a flexible rope ladder for lowering passengers through a broken window. The set is stored in a niche in the luggage compartment. The niche has a cover with a combination lock. The lock is provided against theft of the elements of the kit by passengers. It is also known a device for self-evacuation of train passengers (see RF patent for IZ No. 2707894). This device includes a retractable frame and a casing in which a mat is placed, connected to a gas filling can. The compartment has built-in guides for extending the frame with the casing through the knocked-out window.

The disadvantages of analogs include the need to make changes to the car design, which must be agreed with the car manufacturer, which is practically impossible, given the scale of the changes.

Closest to the proposed PM is the "Device for the evacuation of people" according to RF patent No. 172372 - a prototype. The specified device includes a casing filled with compressed gas, an inflatable mat, a connecting hose with a valve. On one wall of the casing, elastic clamps are fixed to fix the casing on the compartment table. To evacuate passengers, the casing is fixed on the compartment table with clamps, the window is knocked out, the mat is thrown into the window opening and gas is inflated from the casing. People are evacuated through a shattered window, rolling down an inflated mat.

The disadvantages of the prototype include the complexity of the device, since the casing must ensure the storage of compressed gas and the fastening of power clamps to its wall. This complicates the production technology and increases the cost of the device. The technical challenge is to simplify the device for rescuing passengers, reduce its cost, and improve ease of use.

The technical result is achieved in that a portable device for rescuing passengers, mainly from a compartment of a carriage, including a casing equipped with a means of fixation on the compartment table, an inflatable mat, a gas filling can of the mat, is characterized in that said casing is made in the form of a backpack bag having a front and the back wall, connected by at least one quick-release fastener, for example a zipper, the mat is attached to the front wall of the backpack at one end, where the inflation valve is made, while the fixing means is made in the form of a strap, the ends of which are attached to the back wall of the backpack to its sides, moreover, the length of the strap is made with the possibility of covering the tabletop of the table with the strap. In the backpack, the fastener consists of two zippers made with the possibility of connecting the walls of the backpack to each other along their sides and from above. In the backpack, the walls are made of materials, specifically fabrics, in various bright colors, for example, yellow and orange. The backpack has a pocket for a special hammer for breaking the glass of the compartment window.

The utility model is illustrated by drawings. FIG. 1 shows a schematic (not to scale) view of the assembled device; FIG. 2 is a view in a working open position.

In an example of a specific embodiment, the device includes a bag-backpack 1 (hereinafter referred to as a backpack), sewn from durable fabric. The backpack contains front 2 and back 3 walls. The walls are connected with a zipper 4. It is more convenient to use two fasteners, which start at the bottom 5 and converge symmetrically on the sides of the backpack from above. The length of the fasteners 4 ensures the divergence of the walls of the backpack when they are opened, as shown in FIG. 2. In this position, the walls 2, 3 hold the bottom 5. The device for fixing the backpack on the compartment table is made in the form of a strap 6. The strap is attached to the sides of the wall 3. The length of the strap 6 provides coverage of the tabletop 7 of the table located under the window a, which is arranged in wall compartment 8. Inside the backpack are an inflatable mat 9, a gas filling can (hereinafter referred to as a can), a special hammer (not shown). Mat 9 is attached to the wall 2 of the backpack at one end, where there is a valve for inflation.

When assembling the device, special hammers are fixed inside the backpack in a special pocket on the wall 3. The can is fixed on the wall 2 of the backpack. The mat is blown off, the mat valve is connected to the can. The mat is folded into a roll, which is placed in a backpack. The sides of the backpack are connected with clasps. The zipper tongues are tied with twine and sealed. The backpack is stored in the luggage rack in the compartment.

If it is necessary to evacuate passengers through the compartment window, for example, in the event of a fire in the carriage corridor, the compartment door is tightly closed. The backpack is removed from the shelf and placed on the table with the strap down. They put the strap on the table top 7 of the table, move the backpack along the table to the window until it stops. In this case, the strap wraps around the table top, as shown in FIG. 2. Then tear off the seal and unfasten the full length zippers. They open the backpack, take out a special hammer. The glass of the window is broken, the fragments are removed. Then they lift the wall of the backpack 2 together with the mat and throw it into the window opening. The mat unfolds and hangs down, reaching with its free end to the ground. After that, the valve of the can is opened. The compressed gas from the cartridge enters the mat and inflates it. For evacuation, passengers take turns standing on the table, with their feet directly on the wall 3 of the backpack, sit down through the window opening on the wall 2 and slide down the inflated mat, like on an inflatable ladder.

The proposed utility model has a number of advantages over the prototype. First, the source of compressed gas for inflating the mat is a commercially available certified balloon. This ensures the safe storage of the compressed gas and the inflation of the mat. The mat can also be a commercial item. It can be ordered from the beach air mattress factory. The backpack can be ordered from a sports equipment factory. The hammer can be made from ferrous metal waste: a handle made of wire ∅ 10-12 mm, a head made of bar scraps -30 25-30 mm. The manufacturer of the rescue device will only have to assemble the product. A device manufactured using this simple technology will have a significantly lower cost compared to the prototype. At the same time, the fixing device in the form of a webbing strap is much easier to manufacture than steel clips. The proposed solutions reduce production costs and simplify application.

Note that fastening the strap "across" the back of the backpack reduces its attractiveness in the eyes of thieves, since a backpack with such a strap is inconvenient to carry on the shoulder. There may be a thief, but the look of the backpack, the walls of which are painted in unusually bright colors, for example, yellow and orange, immediately catches the eye. Even if the kidnapper manages to deceive the attendant's attention, any passenger can easily notice the "fiery" color of the backpack carried away by an unfamiliar fellow traveler and report the kidnapping to an official.

According to the scheme described above, a prototype of the device was made. The tests showed good results.

The device is proposed for protection by a patent for a utility model.
