Definitions

  • the present invention relates to a lighter, in particular a so-called stick lighter, with the features of the preamble of claim 1.
  • a lighter is understood to mean a special embodiment of a gas lighter which is particularly suitable for lighting candles, gas flames on the cooking stove, fireplaces, barbecues, etc.
  • a stick lighter on a housing with a long-extending, often rod-shaped front area.
  • a fuel usually a liquefied lighter gas such as e.g. a propane-butane mixture, and an actuating mechanism arranged.
  • a fuel line is routed from the tank to the front end of the housing, where an igniter, e.g. a piezo ignition is located. As long as the actuating mechanism is not activated, it interrupts the fuel supply through the fuel line.
  • a lighter is also sometimes referred to as a bar lighter, grill lighter or firelighter, in English as a "Utility Lighter” or “Chimney Lighter”.
  • US 6,669,466 discloses a stick lighter, the securing mechanism of which comprises a knob disposed on an opposite side of the housing from an actuating slide. With the button, a locking element is connected.
  • the locking element has a main portion which extends towards the actuating slide and from which a guide flange extends towards the rear end of the housing.
  • the guide flange blocks the actuating slide.
  • the guide flange releases the operating slide. Since the main section and the guide flange are relatively filigree, there is a risk that the locking element breaks in this construction, whereby the securing mechanism would be ineffective.
  • a lighter according to claim 1 thus comprises: a housing having a proximal end and a distal end, an actuating device which comprises an actuating element which is displaceable relative to an actuating force between an initial position and an actuating position relative to the housing, wherein the actuating device in the initial position Preventing supply of fuel to the distal end of the housing and in the operating position releases the supply of fuel, and - a safety device to prevent inadvertent displacement of the actuating element.
  • the securing device in this case comprises a securing lever, which is connected to the actuating element and is pivotable relative to the actuating element between a locking and a releasing position.
  • the safety lever is in the locking position with a locking element in engagement, which is immovable relative to the housing and thus prevents movement of the actuating element from the starting position to the operating position.
  • biasing means are present, which press the safety lever against a bias voltage in the locking position.
  • a release device is provided which is movable between a rest position and an activated position, wherein the release device in the activated position presses the safety lever against the biasing force of the biasing member in the releasing position.
  • the lighter according to the invention is preferably a lighter, ie, the housing preferably has an elongated shape or at least an elongated front (distal) region, wherein the actuator is located in a region which is remote from the distal end of the housing is.
  • the actuating element is preferably designed as a slide, which is arranged on the upper side of the housing.
  • the slider is designed so that it can be actuated with a thumb.
  • the actuating element is preferably actuated by a displacement on the distal end of the housing. In other words, the actuating element is in the operating position preferably closer to the distal end of the housing than in the starting position.
  • the release device preferably comprises a button arranged on the underside of the housing. This can be pressed from the rest position into the activated position in the direction of the upper side of the housing.
  • the button preferably comprises an activation section, which is in contact, at least in the activated position, with the securing lever.
  • the safety lever is then preferably slidably movable in the activated position of the button on the activation section.
  • the button is preferably designed and arranged so that it can be actuated with a finger while the slider is operated with the thumb.
  • the safety lever preferably has an elongate region which, starting from the pivot axis, extends in the direction of the distal end of the housing. Movement of the elongated portion toward the distal end is then blocked by the locking member when the locking lever is in the locking position.
  • the locking element is located between the elongate region of the securing lever and the distal end, and when attempting to displace the actuating element, the elongate region presses its end against the locking element.
  • the formation of hooks or other features on the safety lever can be omitted, and the safety lever can be made in a simple manner over the entire range from the pivot axis to its front end with approximately constant material thickness and thus with high breaking strength.
  • the biasing means preferably comprise a spring, in particular a helical spring or a (bent over) leaf spring, with a first and a second free end. The first free end then presses against the operating member and the second end against the locking lever so that the spring urges a portion of the locking lever away from the actuating member.
  • the spring is preferably guided around the axis.
  • the screw axis is preferably concentric with the pivot axis.
  • the lighter has a frame arranged in the housing, in which the release device (preferably so the button) upwards, ie in the direction of the housing top to, out.
  • An upwardly projecting projection on the frame then preferably forms the locking element.
  • the actuating element is guided on the frame. In this way, the actuation and securing devices can be realized in a simple manner on a single frame.

The frame 1, however, continues symmetrically on the left side. Again, an X-ray view was chosen to make the spring 44 recognizable. In this view, a horizontal flange 11 on the frame 1 can be seen, which serves to fix the frame in the housing, not shown. For reasons of clarity, the spring 26 in FIG. 4 has been omitted.

Abstract

L'invention concerne un briquet bâton, qui comprend un dispositif de sécurité d'un genre nouveau, pour éviter une utilisation involontaire. Un levier de sécurité (4) est relié pivotant à un élément d'actionnement (2), pouvant coulisser entre une position de repos et une position de service, par rapport à un boîtier, et est précontraint, de sorte à être comprimé dans une position de blocage. Dans cette position, le levier de sécurité est en prise avec un élément de blocage (15), qui ne peut être déplacé par rapport au boîtier, ce qui empêche l'élément d'actionnement (2) de passer de la position de repos à la position de service. Il est prévu un dispositif de libération (3) qui, lorsqu'il est actionné, fait passer par compression le levier de sécurité (4) dans une position de libération, ce qui libère par conséquent l'élément d'actionnement (2).
