CS271278B1 - Personal protective working means with barrier protection's functional distance - Google Patents

Abstract

New types of protection work instruments using functional distance elements for the creation of a closed and opened function gap, improve the isolation effect of barrier protection and hygienic comfort. In the case of opened the air gap the physiological heat and transpired humidity is drawn off thanks to a natural air current. The functional gap is formed by simple layout of distance elements that belong to the barrier protection or form a separated part. The ventilation effect can be increased using an appropriate method of forced ventilation.<IMAGE>

Description

57) New types of protective work equipment with the use of functional spacers to create a closed and open functional gap improve the insulating effect of barrier protection and hygienic comfort in their use. In the case of an open air gap, physiological heat and sweating moisture are dissipated as a result of the natural air flow. The functional bottom is created by simply distributing the spacer elements that are part of the barrier protection or form a separate part. The ventilation effect can be enhanced by a suitable method of forced ventilation.

The invention relates to the improvement of the protective effect of personal protective equipment against adverse effects of the working environment and to the improvement of the sub-microclimate by ensuring optimal separation of one or more protective air layers, e.g.

The prior art solutions of protective clothing and accessories use essentially only barrier protection consisting of textiles, leather, plastics, rubber and the like. These layers provide a sparing impermeability of energy and mass, but they make the thermal-moisture comfort worse the more the barrier protection is impermeable to air and water. Uncomfortable or inferior overheating of the organism increases with work performance and ambient temperature. lun this shortage is often remedied by the addition of cliludunln upůriubml which are often inflexible or restrict the mobility * of the worker.

These drawbacks eliminate personal protective equipment with spacers which permanently delay barrier protection from the body surface or from the basic clothing.

The invention is based on the fact that functional spacers of a maximum height of 10 mm create an air gap between the worker's body surface and the top barrier material of personal protective equipment or, in the case of protective accessories, meciizi and basic clothing such as aprons, various protectors etc. . The air gap provided improves the insulating protective effect and dissipates physiological heat and moisture through natural or even enhanced artificial ventilation. For example, the protective apron of the forge, which is provided with spacers on the inside, improves the thermal insulation from the external heat source and at the same time allows a significant flow of physiological heat through the air flow.

The solution of the invention is illustrated in the accompanying drawings by way of example of a protective apron, where FIG. 1 shows the face of the protective apron, FIG. 2 shows the back of the protective apron according to FIG. 1, FIG. 3 is a cross-sectional view of the apron shown in the preceding figures. Fig. 4 shows another solution of a protective apron, FIG. 5 and 6 show a cross-section through the apron shown in FIG. 4th

Personal protective equipment, eg. the protective apron made of textile, leather, rubber, plastic or other surface is smooth on the face side 1 and spacers 1 or 4 are fastened on the back side 2. Their height varies, but not more than 10 mm. The spacer elements 3 'have the shape of cams ‘/ fig. 4 / or continuous webs - ribs / fig. 3 /.

Claims (3)

The solution according to the invention has achieved an increase in protection efficiency and an improvement in working performance, an improvement in working comfort while minimizing the cost of manufacturing protective clothing, aprons and various protectors. The non-obstructing flexible functionally spacers which can be maintained, in addition to gaining the air interlayer, also soften the effect of weight - the pressure of personal protective equipment on the worker's body. Personal protective equipment with functional spacers are suitable for hot operation of the metallurgical, mechanical engineering, fuel, energy and other industries. In addition, spacers can also be used in the construction of opaque closed overalls for the chemical industry and agriculture when working with chemical spraying, since they improve sub-comfort and thus extend the working time in such overalls. OBJECT OF THE INVENTION Personal protective equipment with a functional barrier protection distance, based on a sheet-like structure, characterized in that elastic spacers (3,4) with a maximum height of 10 mm are fastened to the reverse side (2) of the sheet-like formation. EN 271 27В 01 2. Personal protective equipment dance elements (3) have the shape of perpendicular according to point 1, characterized by ribs - ribs. that the flexible Personal protective equipment according to claim 1, characterized in that the elastic spacers (4) are bodies with a base many times smaller than the areas between which they form an active air gap. 2 drawings CS 271 27B Bl Fig. 2 Fig.3 10mm
