Definitions

  • the present invention relates to the technical field of protective clothing or protective equipment for the foot area, which are designed in particular for military use or for the area of hazard prevention and which in particular have a protective function against radioactive, chemical or biological toxins and / or pollutants, such as warfare agents or which have a corresponding chemical protection function.
  • the present invention relates to a functional footwear unit, in particular in the form of a kit-of-parts, the footwear unit according to the invention being described in claim 1.
  • the present invention also relates to a method for extending and increasing the protective function of footwear, which is described in claim 11.
  • the present invention also relates to the use of an inner shoe material having at least one adsorption material for equipping a functional footwear unit with the aforementioned, in particular modular, protective function or for extending or increasing the protective function of footwear against radioactive, chemical and / or biological toxins and / or pollutants.
  • an inner shoe material having at least one adsorption material for equipping a functional footwear unit with the aforementioned, in particular modular, protective function or for extending or increasing the protective function of footwear against radioactive, chemical and / or biological toxins and / or pollutants.
  • chemical, biological and nuclear toxins or pollutants pose a high risk potential for people who come into contact with such substances, such as soldiers on duty as well as people working in security, such as firefighters or the like .
  • even small amounts or concentrations of the toxins or pollutants in question lead to lasting impairment of health and even death of people who come into contact with or are confronted with such substances.
  • radioactive substances in particular also in the form of radioactive particles or the like, is to be avoided due to the sometimes lasting and permanent damage to health.
  • TICs T oxic I ndustrial C ompounds
  • the limbs are also subject to a great risk potential.
  • special focus should be placed on the area of the foot and on the transition area between the foot and lower leg: Because the aforementioned areas of the body or the items of clothing worn in these areas, such as shoes, are sometimes permanently exposed to toxins in high concentrations in the floor area - or contaminants in contact, which is associated with a high risk of contamination or poisoning.
  • overshoes are used which as such have a certain protective function against the poisonous or harmful substances in question and which are pulled over the actual footwear when in use.
  • a certain protective function against the poisonous or harmful substances in question is also associated with application-specific disadvantages, since optimal handling, in particular with regard to putting on and taking off the overshoe, is not always guaranteed. If the overshoe is put on too late, the footwear is already contaminated, so that optimal protection is no longer provided and, moreover, both the overshoe and the footwear must be decontaminated or disposed of. In addition, the footwear is loaded with additional weight, so that as a result the wearing comfort is also reduced, so that the overshoe is therefore not suitable for long-term wear either. In particular, no efficient sealing is possible in the transition area of the overshoe, specifically also with regard to the transition to a protective suit in the area of the lower leg.
  • footwear in which an adsorption material is firmly integrated in the footwear itself or is a permanent and permanent part of the footwear to ensure a certain protection against poisonous or warfare agents.
  • the textile material described can be used as an upper material for shoes or footwear.

  • the footwear described in the prior art with firmly integrated components to ensure a certain protective function against poisonous or pollutants are generally associated with the disadvantage that the wearing comfort is not always optimal and, in the event of contamination, the footwear as a whole either regenerates or expensively but must be replaced or disposed of, which is also associated with high costs and a corresponding logistical effort.
  • the protective performance of the systems known in the prior art is not always optimal, and an individual adaptation of the protective performance is not possible.
  • shoes of the prior art with a corresponding protective function are sometimes problematic in that, for example, in the event of very high exposure to the underlying toxins or pollutants, in particular if a drop of a liquid poison or pollutant hits the material from a great height, once Toxic substances which have penetrated into the footwear penetrate directly onto the foot of a wearer, which leads to a corresponding contamination with an uptake of the harmful substances by the wearer of the footwear.
  • the stockpiling, keeping or storage of footwear of the prior art with integrated protection against poisonous or harmful substances is complex and costly, since the entire footwear is placed in an outer packaging that protects against premature exhaustion of the protective components or constituents has to be welded.
  • the present circumstance applies to the footwear of the prior art does not take into account that the fixed components of the footwear have different durability.
  • the storage time is largely limited by the limited durability of the sole connection (delamination of the shoe sole), so that after the maximum storage time has been exceeded, the entire footwear with the protective components or parts that are still intact must be disposed of, which is both costly and associated with corresponding logistical effort .
  • the object of the present invention is to provide a footwear unit which at least largely avoids or at least mitigates the disadvantages of the prior art described above.
  • the footwear unit should have an extended or improved protective function against chemical or biological or nuclear toxins and / or pollutants, the footwear unit should be suitable for military use or for use in the field of hazard prevention.
  • a further object of the present invention is to provide a corresponding footwear unit which is improved in its application and handling properties compared to the footwear of the prior art, in which context the handling in the event of contamination as well as the storage or handling. Storage properties should be improved in order to provide a cost-efficient and powerful system on this basis as well.
  • Yet another object of the present invention is to provide such a footwear unit in which the protective function can be individually set or tailored, so to speak, against the background of the respective area of use, the footwear unit at the same time ensuring a high level of wearer comfort.
  • the protective performance should be further improved compared to systems of the prior art.
