Definitions
- the present invention relates to a heater device particularly for inner shoes of sports footwear.
- US-4,507,877 discloses a heater device, particularly for ski boots, which comprises an electric resistance heater arranged along the sole of the inner shoe of the ski boot.
- the electric resistance heater is connected to one or more storage batteries arranged within the inner shoe, and a switch is provided for deactivating the heater device.
- Heater devices are also known which use, as a temporary heat source, one or more bags or containers that contain a substance capable of generating an exothermic chemical reaction if exposed to air.
- US-5,230,170 discloses an insole that is associable with a shoe or a boot.
- Such insole has, preferably in the toe region, a cavity that is suitable to contain a pouch or bag made of a material that allows the passage of air and is filled beforehand with an appropriate mixture made for example of iron powder, water, salt and activated charcoal.
- the user When the user begins sports practice, he removes the bag from a hermetic package, such as a cellophane bag, and places it in the cavity inside the insole.
- the mixture is provided so as to generate, upon contact with the oxygen contained in the air, an exothermic reaction that heats the tip of the foot.
- the duration of the reaction is regulated by the flow of air within the cavity, and said air flow is in turn regulated by the number of holes provided in a removable cover that is suitable to close said cavity, allowing to rest the foot thereon.
- Another drawback is that the foot is not heated effectively in the regions where heating is most needed, but only at the tip of the foot or at the most, at the entire sole of the foot.
- the aim of the present invention is to solve the above mentioned problems, eliminating the drawbacks of the cited prior art, by providing a device that allows to heat the regions of the user's foot that are most exposed to hypothermia during sports activity.
- an important object is to provide a device that allows prolonged use, over time, of the heater device without having to renew the heat source.
- Another object is to provide a device that does not have electrical components, such as resistance heaters, that are easily subject to breakage during use over time.
- Another important object is to provide a device that has low manufacturing costs.
- Another object is to allow, during design, simple and quick changes to the shape of the heater device, aimed at obtaining different constructive solutions in which the regions to be heated are modified, thus adapting the invention to the requirements of each user.
- Another object is to provide a device that can also be applied at nonrigid regions or parts of the inner shoe.
- Another object is to provide a device that is structurally simple and has low manufacturing costs.
- a heater device particularly for inner shoes of sports footwear, characterized in that it comprises a conducting fabric of a known type, which is embedded in said inner shoe advantageously at the forefoot and is connected, at opposite ends, to two or more conductors, which are associated with said inner shoe and connected, at their opposite ends, to connection means for connection to an external source.
- Figures 1 and 2 are perspective views of the invention applied to an inner shoe in two different positions; Figures 3 to 5 are perspective views of three different embodiments of the invention.
- the reference numeral 1 generally designates a heater device that is particularly suitable to be used in an inner shoe 2 of an items of sports footwear, not shown, such as for example a ski boot, a snowboard boot, or a trekking boot.
- the device 1 comprises a piece of a conducting fabric of a known type, designated by the reference numeral 3, which has the feature of warming when electric current flows through it; it is possible to use, for example, the known type of fabric disclosed in PCT patent application WO 00/67528.
- the fabric 3 is embedded in the inner shoe 2, which is soft, and therefore is sewn thereto, advantageously on its inner surface, or can be part of the inner shoe 2 in another manner.
- the fabric 3 is arranged at the forefoot region 4, either above it (Figure 1) or below it ( Figure 2).
- the fabric 3 is associated, at opposite ends designated by the reference numerals 5a and 5b, with two or more conductors 6a and 6b, which are in turn associated with the inner shoe 2.
- Figures 3 to 5 illustrate, merely by way of example, three different types of connection between two ends 5a and 5b of the fabric 3 and the conductors 6a and 6b, so that heating occurs respectively along a longitudinal directrix, along a transverse directrix, or along a plurality of mutually parallel directrices.
- 6a and 6b at the opposite ends 5a and 5b are used which have an elongated shape so as to affect or extend over part or all of the length of the ends 5 a and 5b.
- connection elements 7a and 7b are made of a material with high electrical conductivity, since each one has to constitute a single equipotential region (i.e., a region that has approximately the same electrical potential in every point).
- the conductors 6a and 6b are connected, at their opposite ends, to means for connection to an external source of a known type, not shown in the figures, such as for example an electric storage battery.
- Said storage battery can be accommodated within a suitable seat provided inside or outside the sports shoe, so that it can be recharged or replaced once its charge is depleted.
- CSM control and sensing means
- the user After checking the charge of the power supply batteries, for example by means of a known kind of luminous or other charge indicator, the user can practice the intended sport in maximum comfort, since the heating of the fabric between the opposite ends 5a and 5b allows to keep the foot warm.
- the temperature sensing and control means temporarily interrupt the delivery of current, avoiding excessive temperatures and at the same time ensuring the maximum duration of the electric battery.
- the invention has achieved the intended aim and objects, a heater device for inner shoes having been provided that allows to avoid chilling or freezing of the foot during winter sports.
- the invention further allows to heat any region of the inner shoe, since it can be embedded in any area thereof; in this manner it can be applied, therefore, also at soft regions or parts of the inner shoe, or in regions having a considerable or complex curved shape.
- the heater device has both low manufacturing costs for the manufacturer and low operating costs for the user.
