Abstract

FIELD: rescue means.

SUBSTANCE: invention relates to the field of activity of the services of the Ministry of Emergency Situations (MES) and is designed to rescue people and various objects during their emergency evacuation from high-rise buildings and structures. Jumping rescue device contains a pneumatic chamber made from a durable flexible elastic material and the rods are swivel and supporting. Swivel and support bars, connected by articulation, are installed on the outside of the pneumatic chamber. Upper end of the pivoting bars is equipped with a pulley, which ensures a reliable movement of the halyard when the device is placed in the working position. Hole is made in the lower plane of the pneumatic chamber.

EFFECT: technical result of the application of the proposed invention is due to the fact that the reliability of the life-saving device and the safety for the falling person are increased, since at the moment of the person's fall the possibility of the vertical arrangement of the pivot rods is excluded; the time decreases and the guarantee of air filling of the internal cavity of the pneumatic chamber is increased due to the presence of an opening in the lower plane of the pneumatic chamber and the absence of check valves.

Description

The invention relates to the field of activity of the services of the Ministry of Emergency Situations (EMERCOM) and is intended to save people and various objects during their emergency evacuation from high-rise buildings and structures.

The closest technical solution is a device for the rescue of bodies falling from a height (Patent RU No. 2335312 M. Cl ^3. A62B 1/22, publ. 10.10.2008 in bull. No. 28), containing a pneumatic chamber made of durable flexible flexible material and rotary rods and supporting.

The disadvantages of this device is the location of the rotary rods in the internal cavity of the pneumatic chamber. When the rescue device is installed in the operating position, the upper end of the slewing rods moves along the elastic material in the dry friction mode, which can lead to scuffing and crushing of this material. In addition, unexpected rotation of the pivot rod may occur in an upright position, which is dangerous for a person falling from a height. The presence of check valves in the walls of the pneumatic chamber, which are mechanical devices, reduces the reliability of the rescue device as a whole.

The technical task of the invention is to increase the reliability of the rescue device and safety for a person falling from a height on it.

To achieve the task, in a device for rescuing people from a height, including a pneumatic chamber made of durable flexible elastic material and rods, rotary and supporting, according to the invention, rotary and supporting rods connected pivotally mounted on the outside of the pneumatic chamber, the upper end of the rotary rods is equipped with a pulley, and a hole is made in the lower plane of the pneumatic chamber.

The technical result from the application of the invention is due to the fact that the reliability of the rescue device and the safety for a falling person are increased, since at the time of a person's fall, the possibility of a vertical arrangement of rotary rods is excluded. Reduces time and increases the guarantee of filling the air cavity of the pneumatic chamber with air due to the presence of holes in the lower plane of the pneumatic chamber and the absence of check valves.

A general view of the proposed device is shown in the drawing, where in FIG. 1 shows the device at the end of the installation process; in FIG. 2 - a device ready for accepting a person falling from a height; in FIG. 3 - section of the device before installation; in FIG. 4 - section of the device during installation.

Jumping rescue device contains a pneumatic chamber 1 made of durable flexible flexible material and having the shape of a prism. Rotary rods 2 are installed near the pneumatic chamber 1, the upper end of which is equipped with pulleys 3. The rotary rods 2 are hinged to the supporting rods 4. The hinges 5 are attached to the upper corners of the pneumatic chambers 1, thrown over the pulleys 3. An opening 6 is made in the lower plane of the pneumatic chamber.

The device operates as follows. Upon arrival of the Emergencies Ministry unit to the emergency site to rescue people falling from a height, the unit’s fighters deploy the device to the position shown in FIG. 3. A fighter becomes a fighter for each support rod 2 and picks up the halyard 5. Then, on command, they pull the halyards 5 thrown over the pulleys 3, thereby raising the folded air chamber 1. As it rises (Fig. 4), the air chamber 1 will expand, and through hole 6 it will be filled with air. A fully expanded pneumatic chamber 1 will be lifted above the supporting surface and at this moment the soldiers release the halyards 5 and deflect the rotary rods 2 from the pneumatic chamber 1 and lay them on the supporting surface (Fig. 2). The air chamber 1 falls onto the supporting surface, guaranteed to be filled with air. The device is ready to accept people falling from a height. The kinetic energy of the falling person will be spent on deformation of the volume of the pneumatic chamber 1, which will provide a smooth decrease in the rate of fall of a person.
