Description

The utility model relates to means that provide, if necessary, an emergency exit from the vehicle.

An emergency window is known (RU No. 17906, B61D 25/00, 05/10/2001) containing an elastic frame seal made with a U-shaped groove formed by an external and internal mustache, a double-glazed window with fixed handles mounted in a U-shaped groove, an insert installed in the groove between the double-glazed window and the inner mustache of the seal, profile lock installed in the groove of the seal on the side of the inner mustache and the fixing double-glazed window, grips resting on the lower rounded parts on the grooves in the handle of the double-glazed window and equipped with sealing elements, catch firs and handles with spring pins entering holes in the elastic seal and the grippers arching between the elastic seal and grips the glazing, the insert and the profile-fitted locking checks to remove them catchers grippers.

The disadvantages of the known emergency window are the lack of reliability due to the presence of a massive seal, subjected to brittle fracture at low temperatures, as well as increased labor costs when removing the double-glazed window due to the U-shaped groove of the seal.

A known system profile window "Emergency exit" (RU No. 51951, B61D 25/00, 03/10/2006), containing a double-glazed window, sealed in the frame with the possibility of removal from it using a gripping-fixing device, the frame is made of a combined profile containing an external and the inner parts made of extruded aluminum profiles and connected by the thermal-breaking section, with the double-glazed window seals installed in them, respectively, the outer and inner, the double-glazed window is additionally fixed in the frame with the help of a covering it o along the contour of the belt, fixed at the top of the outer part of the frame by means of at least two screws, the gripping-fixing device is formed by an internal sealant holding the double-glazed window, with a handle fixed on it in the center of the double-glazed window, and a support bracket U-shaped, covering double-glazed window with a belt and a sealant from below.

The disadvantage of this window design is the lack of structural strength due to the use of seals subjected to destruction during vibration and sudden pressure drops typical for operation on high-speed vehicles, as well as the complexity when used as an emergency exit, due to the application of significant efforts to the gripping-fixing device .

The closest technical solution to the proposed utility model is the emergency exit window system for the railroad car (RU No. 82655, B61D 25/00, 08/04/2008). The system of profiles of the window of the railway car "Emergency exit", containing a combined profile of the frame, forming the outer and inner parts of the frame, formed by the outer and inner profiles, interconnected by thermal inserts, and installed in the outer and inner parts of the frame seals frame, glass, outer and inner lining the wagon, the combined profile of the frame is made with the possibility of installing on the frame of the device for lifting the double-glazed window, the system of profiles for sealing the window from the outside contains seals of the frame, the outer casing and the double-glazed window, the outer profile of the frame is made with the possibility of installing a seal in the outer part of the frame and the seal of the outer sheath, and the double-glazed seal is able to seal the glass from the outer and inner sides and remove the double-glazed window with the seal from frames.

The known design, when used as an emergency exit from a vehicle, requires significant efforts to release the window opening from the glass packet after removing the fixation means, this design also has insufficient mechanical strength for high-speed ground transport, as dynamic and vibrational vibrations increase with increasing train speed load on the windows.

The objective of the utility model is to create a window unit for emergency exit from vehicles with high mechanical strength with increased service life without deterioration of operational characteristics during operation and low labor costs when using the window as an emergency exit.

To solve this problem, it is proposed in the window block for emergency exit from vehicles containing a metal frame, a glass insert, a frame and rubber seals, the glass insert is made in the form of a safety laminated glass, consisting of six thermally toughened glasses, alternating with a thickness of 3 mm and 4 mm, and fastened with an ethylene vinyl acetate film, rigidly mounted in a metal frame consisting of two U-shaped profiles, which is rigidly fixed in the outer part of the frame, consisting of the upper and the bottom parts attached through rubber seals to the inside of the frame by means of four locking levers.

The essence of the proposed utility model is illustrated by drawings:

In FIG. 1 shows a general view of a window unit for emergency exit from a vehicle outside the car.

In FIG. 2 - section aa.

In FIG. 3 - glass insert in a metal frame.

In FIG. 4 - shows a General view of the window unit for emergency exit from the vehicle from the passenger compartment.

In FIG. 5 - view B, the locking lever.

In FIG. 6 - sectional locking lever.

The window unit for emergency exit from vehicles contains a metal frame 1, glass insert 2, frame 3 and rubber seals 4, glass insert 2 is made in the form of a safety laminated glass, consisting of six thermally toughened glasses 5, 6, alternating with a thickness of 3 mm and 4 mm , and fastened with ethylene vinyl acetate film 7, rigidly mounted in a metal frame 1, consisting of two U-shaped profiles 8, 9, which is rigidly fixed in the outer part of the frame 10, consisting of the upper and lower parts 11, 12, attached through rubber seal 4 to the inside of the frame 13 by means of four fixing levers 14.

The glass insert 2 of the window block for emergency exit from vehicles is made in this way for the following reasons:

1. Thermally toughened glass 5, 6 has increased mechanical strength, heat resistance and safety when broken. When broken, such glass shatters into many small fragments with blunt edges that are not capable of causing serious injuries to passengers.

2. Ethylene vinyl acetate film 7 holds fragments and prevents foreign objects from getting inside the train compartment when thermally toughened glasses 5, 6 are destroyed.

3. Thermally toughened glasses 5, 6 are made with a thickness of 3 mm and 4 mm, since glasses with a smaller thickness do not provide sufficient structural strength, and the use of thicker glasses, with the same number and sequence, is not allowed, due to the standard overall dimensions of window blocks in passenger trains, as well as in connection with a significant increase in the weight of the entire structure.

4. Six layers of thermally toughened glass 5, 6 of different thicknesses bonded with five layers of ethylene vinyl acetate film 7 are necessary to provide the necessary heat and sound insulation parameters of the window block.

The window block for emergency exit from vehicles is installed in a standard window opening of a passenger car so that the first of the six thermally toughened safety glass panes 5 of laminated glass on the passenger side of the passenger car is 3 mm thick and the first glass 6 on the outside of the car is 4 mm thick .

Installation of the window unit for emergency exit from vehicles is carried out by fixing the inner part of the frame 13 in a standard window opening of the vehicle.

After assembly and installation on the car, the window unit for emergency exit from vehicles is fully ready to perform its functions of protecting passengers, personnel and internal equipment from external climatic, mechanical and sound influences, providing light transmission sufficient to monitor the condition of the railway track, signal readings and surroundings.

To operate the window unit for an emergency exit from vehicles as an emergency exit from a vehicle, it is necessary to turn the locking levers 14 by 90 °, after which, if necessary, push the window out.

Compared with the prototype, the window unit for emergency exit from vehicles has greater mechanical strength with an increase in service life without deterioration of operational characteristics during the entire service life, due to the fact that:

1. Instead of a double-glazed window, a safety laminated glass 2 is used, consisting of six thermally toughened glasses 5, 6, fastened with an ethylene vinyl acetate film 7, has greater mechanical strength, and also, better than the known double-glazed windows of the same thickness, resists mechanical stress, has a large anti-vandal durability and better protects passengers when foreign objects get into the window, thereby increasing the strength properties of the window unit.

2. The metal frame consists of 1 of the left and right parts 8, 9 of the U-shaped profiles. The outer part of the frame 10 of the window unit for emergency exit also consists of two parts, the upper and lower 11, 12. The joints of the frame 1 and the outer part of the frame 10 are perpendicular to each other, which eliminates their combination and weakening of the structure at the joints.

3. Safety laminated glass 2 has the same characteristics of the heat transfer coefficient over the entire service life, in contrast to the double-glazed window, in which the performance decreases over time due to weathering of the gas from the chamber. Even during normal operation, natural weathering of gas from the glass pane chamber occurs. According to studies by Italian scientists at the Stazione Sperimentale del Vetro, Construction Glass Laboratory, the loss of argon from a double-glazed unit is 2-3% per year. Those. after 10 years, even during normal operation of a technically sound double-glazed window, 20-30% of gas will come out of it, which cannot but affect the deterioration of operational characteristics.

4. When using double-glazed windows in conditions of sharp pressure drops and high vibrations that are characteristic of high-speed vehicles, partial depressurization occurs, and moisture can enter the camera, and this leads to a decrease in light transmission. The proposed window unit uses safety laminated glass that does not have such problems.

Compared with the prototype, the window unit for emergency exit from vehicles is more convenient to use when used as an emergency exit, due to the fact that:

1. The rotation of the locking levers 14 takes less effort than pulling the cord from the seals.

2. In an emergency, it is easier to navigate and turn the locking levers 14.

3. The use of the locking levers 14 is more comfortable, as they have large convenient handles, in contrast to the cord.

4. To release the opening for the exit takes much less effort, since there is no need to squeeze the glass.

The surfaces of the proposed window unit for emergency exit from vehicles do not have protruding parts on the outside of the car and lie in the same plane, which is most rational for the design of high-speed vehicles and eliminates additional wind loads and noise when the train moves.

The adhesive joints of the proposed window unit for emergency exit from vehicles provide reliable and tight joints of laminated glass with the frame. After assembly and gluing, the window block for emergency exit from vehicles is a solid structure, the elements of which are hermetically connected to each other, which allows the use of such window blocks in conditions of increased vibration and sharp pressure drops characteristic of the movement of high-speed vehicles.
