  • the foot heating device of the invention which, as stated, has been specifically designed for cyclists, sportsmen and persons living in cold climates, provides to use a control system including a SCRT temperature feedback device, which does not require a broad adjusting range for adjusting the surface temperature of the heater, since, as it occurs for conventional home temperature adjusters, the temperature comfort range for a foot is limited to few degrees in a range of 30°C / 37°C.
  • the foot heating device comprises a temperature adjusting system which is designed for setting and holding a shoe inner average temperature within a comfort temperature range, which can be directly set by the user, depending on the outside temperature variations occurring under the specific conditions and with the desired comfort level.
  • the inventor of the present invention has studied in depth details the energy and temperature ratio, that is the heat amount to be supplied to the system in order to hole a desired temperature, with respect to a system including a foot, a shoe and outside environment.
  • the present invention provides to use a battery set and a temperature adjusting and controlling system, arranged in an ergonomic configuration sealed container, to prevent moisture and dirt from penetrating the container.
  • the above container can be fixed to a supporting element allowing it to be connected to an edge or rim of a shoe, or on a resilient band, for example including Velcro coupling means, to be used in a case in which the shoe rim has not a sufficient size, as in a case of a cyclist light shoe.
  • the above mentioned container comprises, on its outside surface, an adjusting trimmer for adjusting the shoe temperature which can be manually set.
  • said trimmer comprises a graduated bush or ring-nut, allowing to easily set and display a desired temperature.
  • the electronic circuit for adjusting temperature is controlled by sensors arranged near electric resistances applied on the tip of the insole or shoe upper or, optionally, at other portions of the insole.
  • the temperature adjusting assembly comprises, in addition to the mentioned sensors and trimmers, temperature control electronic circuits and power supply circuits allowing to provide optimum results, with a comparatively low current drain.
  • the foot heating device which has been generally indicated by the reference number 1, comprises an insole 2, which can be applied inside a shoe 3 and comprises heating means power supplied by a power or energy source 4.

  • the heating means advantageously comprise one or more electric resistances embedded in the insole 2, and not specifically shown, which are power supplied through an electric cable 6 including a connector 7.
  • the connector 7 can be coupled to a second connector 17 of the power cable 6 in turn coupled to the power source comprising, in this embodiment, a rechargeable battery 4 or a dry battery support element, either of a disposable or of a rechargeable type, which are of any standard types as commercially available.
  • a rechargeable battery 4 or a dry battery support element either of a disposable or of a rechargeable type, which are of any standard types as commercially available.
  • the clamping or fixing means for clamping the energy source can comprise a spat element 5, open at the underlying region, which can be applied to the ankle of the cyclist or sportsman, so as to cover this region and shoe 3, as is clearly shown in figures 2 and 4.
  • the spat element 5 comprises, in particular, a pocket 8 for housing said battery 4 therein.
  • At least the pocket 8 is made of a resilient material, so as to allow the battery 4 to be easily engaged therein and disengaged therefrom, while assuring a proper anchoring of the battery 4 during use, also in the presence of comparatively high stresses generated by the foot movement, during the pedaling operations and, as it should be apparent, by the road unevennesses.
  • the overall spat element 5 is made of a sufficiently resilient material to provide a better fitting and comprises closure means including, in the shown embodiment, a rear hinge closure 9.
  • the materials forming the mentioned spat element 5 must be suitably selected to provide a given thermal insulation and, possibly, even a sufficient perspiration.
  • the spat element 5, moreover, can be optionally made waterproof.
  • Figures 3 and 5 show a further type of clamping means comprising, instead of a spat element, a band 105 which can be applied to the bottom region of the leg, near the ankle of the cyclist.
  • the band 105 comprises, as shown, a pocket 108 for housing therein said battery 4.
  • At least the pocket 108 is made of a resilient material, so as to allow the battery 4 to be easily and quickly engaged therein and disengaged therefrom, while assuring a proper anchoring of the battery 4 during use, even in the presence of a comparatively high stress due to the movement of the pedaling foot and, obviously, because of the road surface unevennesses.
  • the overall band is made of a sufficient resilient material to provide a better fitting and comprises closure means formed, in the shown embodiment, by a closure 109, of the type known on the market as "Velcro" closure or the like.
  • clamping or fixing means The selection of the clamping or fixing means to be used will depend, of course, on the cyclist preference and environmental conditions.
  • the band 33, 105 has the advantage that it is of less size, with respect to the mentioned spat element.
  • the foot heating device according to the present invention can be used in a very simple and easy manner.
  • the clamping means i.e. said spat 5 or band 33, 105 are worn, and the connector 7 of the power cable 6 of the battery 4 is coupled to the connector 17, thereby providing the electric resistances 48 embedded in the insole with power.
  • the position of the battery 4, engaged in the outer pocket 8 or 108 does not affect in any manners the pedaling operation by the athlete.
  • the foot heating device is controlled by an electronic circuit 46 or 47 providing an optimum temperature adjusting of the insole 2 or ferrule 48 and, accordingly, or the cyclist or skier shoe 3, by operating on the trimmer 31 preferably housed in the container or casing 32 of the battery 4.
  • the battery supply 4 and temperature setting system 31 are arranged in an ergonomic configuration sealed container or casing 32, to prevent any moisture and dirt infiltrations.
  • the mentioned container or casing 32 also holds therein the cards 46 and 47 shown in figures 9 and 10.
  • the casing 32 comprises a metal supporting element 5, allowing said casing to be easily clamped on the edge or rim of the shoe 3 or on a Velcro type of resilient band 33, to be used in a case in which the rim of the shoe is of insufficient size, as in a case of a cyclist light shoe.
  • the casing 32 comprises, on its outside surface, a manual trimmer 31 for adjusting temperature, including a graduated ring-nut or bush 34 allowing to easily set and display the temperature values.
  • the power supply battery assembly 4 is electrically coupled to the temperature adjusting circuit inside the casing 32.
  • Said temperature adjusting circuit is coupled with an ultra-flat cable or ribbon.
  • the flat cable 16, 45 passes under the foot bearing surface, in order to provide a good comfort lever.
  • a thermal compensation of the temperature sensors 44 can be performed on the temperature adjusting cards 46, 47.
  • Figure 6 is a schematic view illustrating the basic construction of the foot heating device according to the invention.
  • Said device comprises an insole 2, made of an ultralight and perspiring material, of high mechanical strength, a series of temperature sensors 44 evenly arranged on a surface of a flat heater 48, having an anatomic configuration, by using special metal alloys for forming highly efficient heating resistances.
