  • Lighters are known with various actuating members which afforda more or less simple actuation of the lighters.
  • Pocket lighters mostly have actuating members, such as rollers, hinged covers or spring-pressed levers, which rotate about a horizontalaxis of the lighter.
  • actuating members such as rollers, hinged covers or spring-pressed levers, which rotate about a horizontalaxis of the lighter.
  • the actuation of the burner valve is separated from that of the ignition mechanism, which calls for an additional operating part. This renders the operation complicated and renders more difficult the one-hand operation of the lighter.
  • the invention consists in the novel construction,arrangement and combination of various devices, elements and parts, as set forth in the claimshereof, certain embodiments of the same being illustrated in the accompanying drawings and described in the specification.
  • the instant invention solves these and other aims by an actuating member that is nonnally within the casing contour at rest, but is movable out of the contour of the casing to an active position thereby actuating at least the burner valve and ignition mechanism of the lighter.
  • theactuating member forms part of the side surfaces and of the end surface of the lighter and swings out from a side surface.
  • the actuating member comprises an end surface of the casing and is rotatable about an axis of rotation substantially at right angles to the plane of that end surface.
  • actuating member it is especially advantageous to form the actuating member in sucha manner that the burner valve, flame control, filling valve, flame pit and air louvers may be covered by the actuating member.
  • the actuating member In order to make the flame control and filling valve easier reachable, it is advantageous to provide the actuating member with a releasable holding means or register, such as a notch that becomes effective in-one of the active, open subpositions of the actuating member.
  • a releasable holding means or register such as a notch that becomes effective in-one of the active, open subpositions of the actuating member.
  • the lighter in the closing position may be provided with a releasable holding means, such as a notch that is effective either for the closed position of the actuating member only, or also for the open active position thereof.
  • the actuating member on its surface at the point of application of the thumb, with transverse furrows and/or with a projection.
  • a lid tiltable out of the contour of the lighter which covers in the closed position the filling valve, flame control and a tank observation window.
  • the actuation of the ignition system may be effected by a torsion rod vertically arranged in the casing and which acts as a transmission member between the actuating member and the ignition system.
  • the torsion rod is preferably arranged in a comer of the casing, and may also be in the form of a torsion spring.
  • FIG. 1 is a schematic perspective view of a lighter with a lever as an actuating member, showing parts of an end surface and two side surfaces;
  • FIG. 2 is a schematic perspective view similar to FIG. 1 but showing a modification wherein the actuating member forms a part of a side surface and of the end surface of the casing, at rest;
  • FIG. 3 is a perspective view of a modified embodiment wherein the actuating lever forms a part of a side surface
  • FIG. 4 is a perspective view, partly in section, of a modified lighter, the actuating lever of which is likewise formed by a part of a side surface and which reaches into the end surface, and which illustrates a torsion rod;
  • FIG. 5 is a perspective view of a modified lighter with an actuating lever that closes with the end surface opposite to the side of the flame opening;
  • FIG. 6 is a perspective view of a modified lighter the actuating member of which comprises the end surface and a part of a side surface and is rotatable about an axis at right angles to the plane of the end surface, showing the lighter at rest;
  • FIG. 7 is a perspective view similar to FIG. 6, but showing the lighter in operating position
  • FIG. 8 is a perspective view of a modified lighter showing in addition to the actuating lever also a lid for covering the flame control and the filling valve, as well as an observation window for the tank, with both the actuating lever and the lid closed;
  • FIG. 9 shows the lighter of FIG. 8, but with the actuating lever in active, open position
  • FIG. 10 shows the lighter of FIGS. 8 and 9, but with the lid in open position uncovering the flame control, filling valve and the observation window.
  • FIG. 1 shows a lighter with a rectangular casing l and an actuating member in the form of a lever 2.
  • the lever 2 is rotatably mounted in a comer of the casing. l and is movable horizontally about a vertical axis, from a position wherein at least a portion of the exterior of the lever 2 coincides with the corresponding portion of the contour of the casing I, out of the contour of the lighter.
  • the lever 2 comprises a surface 21 which is simultaneously the end surface of the lighter at rest, as well as the sidewalls 22 and 23, the outer surfaces of which coincide in the rest position of the lever 2 with the surfaces 12 and 13, respectively, of the casing I.
  • the actuation of the lighter is effected by clasping the lighter with the hand and by moving the lever 2 horizontally by sidewise pressing on the outer surface of the sidewall 22 which may be provided with friction means such as, for example, vertical channels (FIG. 5) transverse to the actuation direction and/or with a projection (FIG. 3). Thereby the ignition mechanism and the burner valve will be activated.
