Definitions

  • the present invention relates to a device for adjusting the power in a heating circuit for ski boots.
  • Said electric resistors are powered by means of adapted accumulators accommodatable within convenient seats provided for example on the shell and/or on the quarters.
  • power adjustment occurs by means of generally electronic devices which, the maximum value of delivered current being equal, act on the duration of the pulse of current.
  • Said devices besides being rather complicated, have a large number of components, and are therefore uneconomical and difficult to integrate in the boot.
  • the main aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a device which allows to adjust the power in a heating circuit, according to the specific and contingent requirements of the skier, while being at the same time structurally very simple.
  • Another important object is to provide a device which is reliable in use and allows an effective adjustment of thermal power.
  • Not least object is to provide a device which has modest costs and is easily integratable in the boot.
  • a device for adjusting the power in a heating circuit for ski boots comprising at least one power source for at least one resistor, characterized in that it is constituted by at least one switch sectioning and/or selecting said at least one power source and/or said at least one resistor.
  • At least one discharge limiter for said at least one power source is present in said circuit.
  • said at least one switch is manually actuatable by the skier.
  • the numeral 1 indicates an electric circuit particularly for the heating of ski boots.
  • the electric circuit comprises a power source 2 and three resistors indicated respectively by the numerals 3a, 3b and 3c arranged in series to one another.
  • Said resistors may advantageously be identical.
  • the circuit furthermore comprises a switch, indicated by the numeral 4, having four different positions.
  • Said switch allows the supply of power to all three resistors 3a, 3b and 3c or the supply of only the resistors 3b and 3c or the supply of only the resistor 3c or the interruption of the electric circuit.
  • a discharge limiter is present in the circuit between the power source 2 and the switch 4.
  • Figure 2 illustrates a practical use of the circuit applied at an insole 6.
  • the power source is constituted by accumulators 7 connected to a resistive film 8 associated at the foot tip region of the insole 6, a box-like structure 9, accessible to the skier, accommodating the switch 4 and/or the discharge limiter 5.
  • the use of the discharge limiter allows to prevent phenomena of reverse polarization due to deep discharging of the accumulators.
  • the use of the device allows the skier to select the switch 4 in the position most suitable to obtain the desired degree of heating of the boot; in fact, according to the inner temperature thereof, he may opt for a different degree of heating therefore effectively adjusting the thermal power.
  • the invention achieves the intended aim and objects, a device having been obtained which allows to adjust the power in a heating circuit according to the specific requirements of the skier, the device being at the same time structurally very simple, reliable in use and easy to integrate in the boot.
  • the effective adjustment of thermal power furthermore allows to achieve the heating of the boot in an economical and completely reliable manner, the skier being able to manually select different electric configurations according to the desired amount of heat.
  • figure 3 illustrates a circuit 101 comprising a power source 102 and a three-position switch 104, a discharge limiter 105 being arranged between said switch and said power source.
  • the switch 104 allows to alternately select, in the circuit, either the resistor 103a or the resistor 103b, both naturally having different values.
  • the third position of the switch 104 allows to keep the circuit open.
  • Figure 4 instead illustrates a circuit 201 comprising three power sources, indicated by the numerals 202a, 202b, 202c, arranged in series.
  • the circuit furthermore comprises a single resistor 203 and a four-position switch 204 adapted to select the desired one among the three power sources.
  • separate discharge limiters indicated by the numerals 205a, 205b and 205c, are present between said power sources and the switch 204.
  • Figure 5 illustrates a third circuit 301 comprising three separate power sources arranged mutually in series and indicated by the numerals 302a, 302b and 302c.
  • the circuit furthermore comprises a single resistor 303.
  • the circuit furthermore comprises a double four-­position switch 304, adapted to select the desired power source, and a discharge limiter 305 arranged downstream the switch and having separate internal circuits according to the selected power source.
  • the materials, as well as the dimensions of the individual components of the device such as for example the values of the resistors, of the power sources and their number, may be the most suitable according to the specific requirements.
