Description

The invention relates to stationary rescue triggers for evacuating people from windows and balconies of a building in case of fire.

Known rescue system for high-rise buildings (RF patent No. 2288759, A62B 1/02, publ. 10.12.2006). The device consists of a lifting mechanism installed at the end of the roof of the building, which is a winch with an arrow, a cable suspension, a rescue cabin. The rescue cabin is connected via an additional cable to a second similar lifting mechanism with an arrow and a winch mounted on the other edge of the roof with the possibility of changing the horizontal position of the rescue cabin. Each winch is equipped with a stepper motor associated with a control synchronizing mechanism. The arrows are made lifting, two-bearing and equipped with blocks that can be rotated relative to the central longitudinal axis of the boom and alarm, and at least one of the arrows is made U-shaped with the possibility of placing in the initial position of the rescue cabin between the supports. The disadvantage of this invention is the complexity and narrow scope.

Known trigger device, taken as a prototype (AS USSR No. 1144710, A63B 29/02, publ. 15.03.1985). The device comprises a block section (trigger device) for passing the rope, equipped with a base and a cover, as well as a movable brake element and guide rollers equipped with a handle mounted on the base. The brake element is made in the form of a spring-loaded roller equipped with a handle. The descent of a person is carried out by pressing and holding down the handle associated with the spring-loaded roller. In the absence of effort on the part of man, a spring-loaded roller clamps it under the influence of a loaded rope, thereby braking. The disadvantage of this invention is the complexity and narrow scope.

The technical result of the invention is to simplify the design and expand the scope of applications of devices of this type due to the possibility of use in equipped openings for evacuation.

The technical result is achieved in that in a rescue system for high-rise buildings containing a life jacket, a rope, a trigger device with a brake element and a guide roller, according to the invention, a trigger device mounted on a life jacket is made in the form of an articulated carbine with a brake element and adjusting screws with locking the carbine with a lock, and the rope is mounted on a drum mounted in the upper part of the evacuation opening, with a rope capacity equal to the height of the drum, brake ment is designed as a brake lining fixed on the base, connected with adjusting screws.

The application of the invention in comparison with the prototype will simplify the design and expand the scope of devices of this type due to the possibility of use in equipped openings of any type.

The rescue system for high-rise buildings is illustrated by drawings, in which Fig. 1 shows a cross-section of a hinged carbine, Fig. 2 schematically shows a life vest with a trigger device mounted on it, and Fig. 3 schematically shows a installation diagram of a rescue system relative to a high-rise building.

The drawings show:

1 - articulated carbine (trigger device);

2 - hinge of a carbine 1;

3 - a directing roller;

4 - adjusting screws;

5 - carabiner lock 1;

6 - rope;

7 - brake lining, mounted on the base 13 associated with the adjusting screws 4;

8 - high-rise building;

9 - aperture for evacuation;

10 - drum with a rope capacity equal to the height of its installation;

11 - locking carabiner;

12 - life jacket;

13 - the base associated with the adjusting screws.

The rescue system for high-rise buildings contains a launching device and a drum 10 with a rope 6. A drum 10 with a rope capacity equal to its installation height is fixed in the upper part of the opening 9 for evacuation. The trigger device mounted on the lifejacket 12 is made in the form of an articulated carbine 1 with a guide roller 3 and adjusting screws 4. Adjusting screws 4 are used to adjust the braking force when lowering people by acting on the base 13 with a brake lining 7 fixed to it, interacting in turn with a rope 6. In the immediate vicinity of the opening for evacuation 9, a box with rescue devices, consisting of a launching device 1, mounted on a life jacket, is installed 12. The trigger device 1 is fixed on a life jacket 12 with the condition of its being on the chest of the evacuated person.

Rescue system for high-rise buildings works as follows. In case of emergency, people are sent to the opening for evacuation 9 to put on individual lifejackets 12 with triggers 1. A person puts on a lifejacket 12, snaps the locking carabiner 11, and then goes to the opening 9 for evacuation. After that, or in parallel with putting on the rescue devices, the rope is lowered 6. Before the descent, the evacuated person places a cable 6 between the groove of the guide roller 3 and the brake lining 7 and fixes the carbine 1 with the lock 5. Then, using the trigger device, 1 person descends to the base of the high-rise building 8. Speed The shutter release is a predefined value and can be adjusted with screws 4.

The use of the rescue system for high-rise buildings provides the following benefits:

- simplification of the design of the device;

- expanding the scope of devices of this type.
