Definitions

  • the invention relates to lighters, and relates more particularly to small lighters, known as pocket lighters, that have a housing that for the major part is composed of metal, and furthermore includes an igniter that comprises a coil.
  • the vocational step wound coils have much smaller external dimensions than cylindrically .wound coils, so that magnetic igniters with vocational step wound coils at comparable output have much smaller volume.
  • Pilgrim step wound coils for the instant purpose may have a length of less than three-fourths in. and a width smaller than seven-sixteenths in.
  • a pocket lighter As previously indicated, magnetic igniters are particularly suitable, due to their small dimensions, for use in pocket lighters.
  • a pocket lighter reference is had to Design Patent No. D2l7,496 of Dieter Rams, dated May 5, 1970.
  • dimensions of such a pocket lighter may include a length of about 2 It in., a width of about 1 A in., and a thickness of about one-half in.
  • the coil of the igniter forms with the housing a condenser, the capacity of which depends onthe distance between the coil and the housing.
  • the capacity is inversely proportional to the distance between the coil and the housing, so that an increase of said distance would lower the capacity.
  • the larger that capacity is, however, the greater the losses of energy for the coil and hence for the output of the igniter. It is therefore desirable to have a large distance between the coil and the housing, in order to keep the losses at a minimum.
  • the instant invention provides for a pocket lighter with a magnetic igniter including a coil that has a metal housing which surrounds the igniter and includes a large metal portion that, however, defines near the place of the coil an aperture or apertures, and an insulating cover is, or covers are, provided for the aperture or apertures.
  • the aperture or apertures are formed in the wide side walls of the lighter.
  • the instant invention offers the advantage of such a pocket lighter with small dimensions substantially free from capacitor-generated losses of magnetic ignition output losses.
  • FIG. 1 is a schematic perspective view of a lighter in accordance with the invention
  • FIG. 2 is a sectional view thereof, taken on the line 2-2 of FIG. 1;
  • FIG. 3 is a fragmentary additional view, similar to FIG. 2 but embodying a modification.
  • FIG. 1 there is provided a housing 1 for the pocket lighter.
  • An operating mechanism 2 for the igniter is provided and the igniterincludes an electrical coil 5.
  • the housing 1 for its major portion is composed of metal.
  • the housing 1, however, defines one or more apertures 4 and 8, respectively, facing the coil .5 of the igniter, and an insulating cover, such as an insulating plate 3 is provided for each of the apertures 4,8.
  • the material of the insulating plate may be synthetic plastic material, or glass or ceramics or the like.
  • the coil 5 is so arranged in the housing 1 that its external dimensions almost coincide with the internal dimensions of the housing 1.
  • the wide side walls of the housing 1 are indicated at 6 and 7. 9 and 10 designate parts of the magnetic portion of the igniter.
  • a pocket lighter having a metal housing including wide and narrow opposite sidewalls, an electromagnetic igniter surrounded by said housing and including an electromagnetic coil closely fitting in said housing, said metal housing having an aperture in each of said wide opposite sidewalls, said apertures being adjacent and larger than said electromagnetic coil to restrain the occurance of a condenser efiect, and an electrically insulating protective cover plate closing each of said apertures.
  • a pocket lighter as claimed in claim 3, said insulating plate being composed of synthetic plastic material.
  • a pocket lighter as claimed in claim 3, said insulating plate being composed of glass.
  • a pocket lighter as claimed in claim 3, said insulating plate being composed of ceramic material.
  • a pocket lighter as claimed in claim 7, said apertures defining opposite spaces, said coil extending into said spaces, said plates being disposed outside said spaces.
