Definitions

  • This invention relates to the field of worn devices for controlling body temperature. More specifically it relates to hats designed to provide heat protection in high temperature environments.
  • Sauna systems (throughout the description of this invention it will be understood that the word 'sauna' is used in reference to any kind of enclosed spaces with artificially increased temperature, including steam baths, steam rooms and similar) are used in order to utilize therapeutic and cleansing effects of heat. Heating in such a controlled environment causes the human body to perspire and it can also provide therapeutic effects (thermotherapy) regarding muscles and joints, help improve blood flow inside particular body tissues. For these reasons saunas are becoming more popular and therefore more various spa and bathhouses are providing sauna services. Inside such sauna rooms, trained employees are often required to provide various services for extended amounts of time, without leaving the high temperature and abnormal humidity environments.
  • One solution includes the use of so called sauna hats. Since the human head is most susceptible to the adverse effects of increased heat conditions, it is a common practice to use such hats during sauna sessions. Such hats are usually made from wool felt, which is a good thermal insulator, and are often of a conical (but not limited to) shape. A felt hat protects the human head by decreasing the rate at which heat is absorbed from the hot ambient environment, thus making the natural process of body thermoregulation less difficult and extending the tolerable duration of the sauna session. Such hats extend a sauna session, but do not provide the necessary heat protection for an employee working in the sauna, since the human body can only cool itself while being in an environment cooler that the normal body temperature. The hat only provides limited insulation and only slows the accumulation of heat. To solve this problem a number of possible solutions have been proposed that could be adapted for sauna environment applications.
  • a US patent No. US2009205107 published on 20-08-2009, describes a hat for cooling the head of a wearer having a chamber comprising a central cavity and at least one opening for placing ice into the cavity; and at least one porous member secured to one end of said chamber; wherein the apparatus is configured to be attached in a demountable way to the head of the wearer.
  • FIG. 1 Another US patent No. US5197292, published on 30-03-1993, describes a headwear device for cooling the wearer during athletic activity or work.
  • the device is comprised of a cap having interior and exterior surfaces. At least one opening to at least one defined compartment chamber within the cap.
  • the chamber is formed within the interior and exterior surfaces of the cap.
  • the chamber interior having at least one surface made of material capable of fluid transmission from the chamber interior to the cap's interior surface.
  • a Germany patent No. DE202005009524 published on 16-03-2006, describes clothing-based active cooling system for the human body functions in conditions of high ambient temperature. It covers by virtue of its formation one or more points of the body by means of contact and/or encloses them. It comprises a material capable of fluid storage, which accommodates a fluid capable of evaporation. It can store the fluid and eventually emit it.
  • prior-art inventions include the use of materials other than water or ice and other techniques designed to provide heat protection.
  • materials might include dry ice (as described in a Japan patent No. JPH0947467, published on 18-02-1997), or other materials (for example as those used in specialized thermal packs) with different melting and sublimation temperatures and other characteristics (China patent No. CN201536656, published on 04-08-2010).
  • Such materials are not readily available to a domestic user and therefore make the devices utilizing them more complex, relatively expensive to produce, harder to maintain and apply.
  • more complex cooling techniques might include the use of liquid conveying hoses, tubes or capillaries (for example as described in an European patent No. EP2236048, published on 06-10-2010) or specialized multilayer fabrics, which increase production costs and reduce flexibility of the device to be attached to the human body.
  • this invention provides a head worn thermal heat protection and cooling device.
  • the device will be referred to as the 'cooling hat'.
  • the cooling hat is formed from a single layer non-woven wool felt or similar material in a manner that it constitutes a single piece of headwear (1) that can cover the head (2) and the upper part of the human body.
  • the thickness and density of the material is chosen in such a way to provide effective thermal insulation and the ability to slowly soak up water, with local variations (3) in thickness and density to provide comfortable flexibility.
  • the cooling hat has a at least one compartment chamber (hat cavity) (4) in which one or more types of solid coolant (5) can be deposited.
  • the device features at least one preferably closable opening (6) for depositing the solid coolant inside the compartment chamber (4).
  • the sauna cooling hat provides thermal insulation together with a cooling effect, based on combination of effects of solid coolant melting, heat absorption by liquid coolant and vaporization of a liquid coolant.
  • This invention provides a head worn thermal heat protection and cooling device.
  • the device can be adapted to be used as different kinds of head wear or combined with different garments.
  • the device is arranged as a hat or a hood designed for use in a sauna room during a sauna session or other high temperature environments.
  • the device features a preferably single compartment chamber (4) with a closable opening (6).
  • the closure means can be comprised of preferably a zipper or buttons or a Velcro sticker type closing means (not shown in figures) or similar.
  • the said chamber (4) is filled with a coolant (5), preferably crushed ice (5) or snow.
  • the ice (5) melts absorbing heat from the upper part of the head (2) and ambient heat from the close vicinity of the head (2), and also providing a source of cool water for wetting the hat material, further providing cooling by wetting the user's skin and hair with cool water and providing cooling by evaporation.
  • the hat material is a non-woven fabric, preferably wool felt, having good thermal insulation properties, thus reducing the absorption of the ambient heat through the covered body surface area, and capable of slowly absorbing and evaporating the liquid.
  • the hat is made without stitches (with the possible exception of the site of closing means (6)) from a monolayer of the felt material.
  • the hat can be made featuring regions (7) of reduced local thickness (3) or density of the hat material.
  • the positioning of reduced local thickness or density sites (7) is optional and dependent on the design of the hat.
  • the hat can be made to cover the head (2), neck (8), back (9), shoulders (10) and the chest (not shown in figs) of the user, protecting those areas from heat and providing cooling.
  • a device arranged in such a way is especially suited for the use in a sauna room, regardless of temperature or humidity.
  • the chamber compartment (4) is filled with suplementary coolant materials, such as dry ice or other.
  • the non-woven material on hat's top is arranged in such a way that when the solid coolant (5) melts or sublimates the chamber compartment collapses or folds itself in a predetermined manor reducing the volume of space taken up by the hat (see Fig. 5).
  • the chamber compartment is additionally filled with a mixture of aromatic substances or medicine to provide additional therapeutic effects.
  • the aromatic substances or medicine is evenly delivered to the user's skin throughout the process of diffusion through the wool felt fabric.
  • the hat's fabric features a thickness and density gradient, to provide a selective distribution of thermal insulation and cooling over the covered body areas.
