Definitions

  • the invention is an apparatus for heating or warming the extremity of a skier.
  • a resistance heater is positioned adjacent an extremity of the skier and a current generator is secured adjacent the ski boot.
  • the generator is electrically connected to the resistance heater.
  • a connecting member extends from the generator to a point located on the ski behind the ski boot. Relative movement between the generator and the fixed point on the ski is mechanically transmitted to the generator thereby generating current to the resistance heater.
  • This invention relates to an apparatus for heating or warming the extremities of a snow skier or person engaged in outdoor activity. More particularly this invention relates to an apparatus particularly adapted for warm ing the feet or hands of a skier by utilizing the continuous movement made by such person while skiing to generate an electrical current which is used to energize an electrical resistance heating wire embedded in the clothing covering the skiers extremities.
  • U.S. Pat. 2,692,326 discloses a battery powered, electrical heating device for use in the shoes of a wearer. This device, while completely portable and enabling the wearer to travel independently of a fixed power source, must rely upon batteries of limited energy capacity.
  • Current development in the art of electrical generators has made possbile the use of highly efficient, compact and light-weight generating units which require a minimum of mechanical power to generate an amount of electrical power sufficient to heat a fine resistance wire which may be used to selectively warm certain portions, such as the hands or feet, of persons exposed to the elements.
  • FIG. 1 is a side view in elevation showing a ski boot with a portion of the wearers leg therein, and an embodiment of suitable electrical generator attached thereto and to a portion of a ski;
  • FIG. 2 is a cross-sectional view of the electrical generator shown in FIG. 1, shown on an enlarged scale and taken along the line 2-2 of FIG. 1, showing the construction details of this preferred embodiment, and;
  • FIG. 3 is a cross-sectional view on an enlarged scale, as it would be seen in full section from the position of line 33 of FIG. 2, and showing the details of the embodiment of the generator.
  • a single ski boot 10 with a portion of the wearers leg 11 inserted therein is shown held on a ski 12 by means of a conventional ski harness 13 which includes a spring mounting 14.
  • the spring mounting 14 extends around the heel 15 of the ski boot 10 and permits the wearer to rock forward on the ball of his foot, raising the heel 15 off of the upper surface of the ski 12, to the position shown in phantom and indicated by reference numeral 11a. This rocking motion is practiced by a skier to shift his weight forward and back on the skis, depending upon his speed, position and nature of the slope being traversed.
  • a winding or filament of a fine wire resistance heating element generally designated by reference numeral 1 6 which encircles the foot of the wearer or may be entirely below the wearers foot, such as in the sole of the ski boot or stocking.
  • the wire is shown as being within the lining of the ski boot, but it is to be understood that it may be incorporated within the stocking of the wearer or, if desired, within the mittens of the wearer.
  • the ends of the resistance heating element 16 extend upwardly through the top of the boot and are attached to a pair of output terminals 17 which are a part of an electrical generator, generally designated by reference nu meral 18.
  • a flexible tension member 19 whose purpose will be subsequently explained, extends from the lowermost portion of the electrical generator 18 and is secured to an eye or other appropriate fastening 20 on the upper surface of the ski 12, to the rear of the heel 15 of the boot 10.
  • the body of the electrical generator 18 has a plurality of strap loops 21, also seen in FIG. 2, which receive a pair of straps 22 and 23 which encircle the upper portion of the ski boot 10 and securely hold the generator 18 in position.
  • one preferred embodiment of the generator 18 includes a rotor 24 mounted on the shaft 25 which is journaled for rotation within the external frame 26 of the generator 18.
  • a flywheel 27 is also secured to the shaft 25.
  • a ratchet wheel 28 having external ratchet teeth 29, as best seen in FIG. 3, is journaled for rotation on a shaft 30 which is spaced from and parallel to the rotor shaft 25.
  • a recessed, internal tooth ring gear 31 is integrally formed and coaxial with the ratchet wheel 28, as best seen in FIG. 2, and is of a diameter so that the inner teeth 32, best shown in FIG. 3, mesh with a pinion 33 secured to the adjacent end of the rotor shaft 25.
  • a pivot arm 34 is secured to a fixed pin 35 on the casing 26 of the generator 18 and has a ratchet pawl 36 pivoted on one end thereof.
  • the opposite end of the pivot arm 34 is attached to the tension member 19 which extends through an opening 37 in the lower portion of the casing 26.
  • the free end of the ratchet pawl 36 has a tooth engaging dog 38 which, when in the position shown in FIG. 3, is held out of engagement with the ratchet teeth 29 by a detent 39.
  • the system thus described which uses the natural motion of a skier or other person engaged in traveling through the snow, can be used to power a heating element disposed in any part of the wearers body, and not just the foot thereof.
  • the generator which converts the movement of the skier to a rotary movement for driving the generator, can be utilized by persons skilled in this art. Because the power source for these heating elements is dependent, not upon expendible batteries, but upon the continued movement of the user, the apparatus described herein has advantages over those known in the prior art in that the power generated therefrom is available so long as the person remains engaged in his out-of-doors activity.
  • An apparatus for heating the foot of a person wearing a ski boot with a ski attached thereto comprising in combination, a resistance heating element disposed within said ski boot, a current generator means secured to the rear portion of said ski boot, said generator means having output terminals electrically connected to said heating element and having a magnetic field, and a rotor positioned to cut magnetic lines of force from said field and thus generate electrical current to said output terminals when rotated, a flexible member extending from said generator means and secured to a fixed point on said ski behind said ski boot, and means for converting movement of said generator means relative to said fixed point to rotary movement of said rotor whereby the movement of said generator caused by movement of the upper part of said ski boot relative to said ski by said person drives said rotor and thus generates current to heat said ski boot.
  • the means for converting generator movement to rotary movement includes a toothed ratchet wheel coaxially secured to said rotor and a spring biased ratchet pawl secured to said flexible member whereby tension placed on said flexible member through movement of said generator away from said fixed point causes said pawl to engage and drive said rotor and whereby the subsequent release of tension on said flexible member will cause said pawl to return to its previous position without interfering with movement of said rotor.
  • Heating apparatus for use by a skier wearing a ski boot with a ski attached thereto, said heating apparatus comprising, in combination, a resistance heating means positioned adjacent an extremity of the skier, a current generator means secured adjacent such ski boot, said current generator means having output terminals electrically connected to said resistance heating means and having a magnetic field and a rotor, wherein electric current is generated to said terminals and to said resistance heating means when said rotor is rotated, a connecting member extending from said current generator means to a fixed point located on said ski behind such ski boot, and means located adjacent said current generator means and operatively connected to both said current generator means and said connecting member for converting movement of said current generator means relative to said fixed point to rotary movement of said rotor, thereby generating current to said resistance heat- JOSEPH V.
