Boots rescuers working in extreme conditions

摘要

The invention relates to a means of personal protection against vibrations, in particular structure rescuer shoes comprising resilient cavity.; Technically achievable result - increasing the effectiveness of protection against vibration and the rescuer providing increased comfort shoes when walking with minimal costs during manufacture.; This is achieved in that the boot rescuer working in extreme conditions, comprising a bootleg and vibration-proof soles with a sealed cavity disposed in the lower part and provided with a check valve for communicating with the external environment and a source of compressed air, a sealed cavity is connected by a throttling sleeve with damping vena chamber made of a rigid vibration-damping material, for example plastic such as "agate", "Antivibrit", "Shvim", and situated inside the heel and over the sealed cavity taken at equidistant and congruent her elastic hermetic shell filled with silicone fluid, and above it is an insole made of a needled material such as "shale shakers" based on silica or aluminoborosilicate fibers, than can be used vibration absorbing material such as an elastomer as the sole material, or polyurethane with a degree of porosity in the range of optimal values ​​of 30 ÷ 45%, and the form damping chamber may be formed as a polyhedral, e.g. in the form of a cube, and drawing so Call rotational bodies, such as a cylinder, sphere, as well as materials sealed elastic-damping cavity and elastic containment following may be used: elastomers, such as tires, a casting resin, for example polyurethane, rubber-shell, wherein a damping chamber in its middle part, is rigidly connected to the protective insert is made of a more rigid than the sole, elastic material and functions as an additional vibration-proofing elastic element in the system "shoe-person".
