FIELD: personal demand items.
SUBSTANCE: batt footwear of rescuer for operation in low temperature conditions containing the top, the feet part and the main sole located from the lower side of the feet part, while the protective sole located from the lower side of the main sole is made of material , or from EVA compound with rubber, or from EVA compound with PVC, or from EVA compound with polyethylene, in addition it contains the plate which is implemented with heating from an ethylene vinyl acetate or another elastic material, and into heel part of the plate the piezoelement from a piezorubber, for example from polydimethylsiloxane with the thickness 2.5÷5 mm, with the size 10×10 mm is inserted, meanwhile it is placed into the protective shell, and the heating thread is connected minimum to one piezoelement located in the heel zone and/or the sock zone, and the supplementary vibroprotective plate with anatomic shape located between the main sole placed from the lower side of feet part, and the protective sole located from the lower side of the main sole, contains the bearing plane with the bushings fixed on it where elastic elements are located, for example the springs contacting with the damping three-layer unit containing the plates from the rigid vibrodamping material, for example of Agate type between which the layer of the polyurethane is located which damps vibration at medium frequencies, while the elastic elements contacting with the damping unit, are implemented in the form of conic springs, having equifrequent properties, and spring turns are coated with the layer of vibrodamping mastics, for example of VD-17 type, or polyurethane, and the internal cavity of each spring is filled with layers of viscoelastic mesh elements.
EFFECT: providing more comfortable wearing of batt footwear due to footwear weight saving, creation of clean hygienic atmosphere in internal cavity of feet part, and possibility to work in conditions of low temperatures, for example in conditions of Far North.
