Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a guide device for a control lever in a smoking gas lighter.

(Prior Art) Conventionally, in a gas lighter for smoking, a piezoelectric generator is disposed in a lighter casing in parallel with a fuel tank, and in order to operate the piezoelectric generator and open a burner valve device. 2. Description of the Related Art Smoking gas lighters having an operating lever that can be depressed freely are known.

It is necessary for such an operation lever to accurately guide its operating direction in the vertical direction to reliably transmit operating force to the piezoelectric generator. Therefore, a structure has been proposed in which the operating lever and the main body are guided in the vertical direction by engagement between a vertically extending key and a keyway, and is disclosed, for example, in Japanese Utility Model Publication No. 57-32373.

(Problems to be solved by the invention) In the structure disclosed in Japanese Utility Model Publication No. 57-32373, projecting walls are formed parallel to the operating lever, and a part of the frame is positioned between the projecting walls. Since the protruding wall and the frame positioned therebetween are engaged by a key and a keyway, the structure is complicated and the cost is high.

In addition, if the upper surface of the control lever is not a flat surface but is formed as a slope or an arcuate surface that descends slightly toward the rear, the control lever will slide backward while being pushed downward by the finger pressure applied to the control lever. Therefore, in addition to a vertical force, a horizontal force perpendicular to the vertical force acts on the operating lever, and there is a risk that the operation of the operating lever may not be smooth.

(Means for Solving the Problems) In order to solve the above problems, this invention has a piezoelectric generator 2 inserted into one side of the lighter body 1 which has a built-in fuel tank, and A columnar electrode stand 4 is erected, facing the burner nozzle 5 while holding the lead wire 7, and two L from the tip of the operating lever 10 linked to the piezoelectric generator 2 are connected.
The electrode base 4 has arm pieces 14, 14 extending facing each other, and the arm pieces 14, 14 form a substantially rectangular frame shape and surround and engage with the outer peripheral surface of the electrode base 4. It is also characterized by being elastically expandable and contractible by the gap between the opposing tips.

(Function) Two opposing L-shaped arm pieces extending from the tip of the operating lever lock onto the columnar part that holds the electrode and guide the operating lever in the vertical direction. It can resist the applied horizontal force, and the operating lever will not tilt.

(Effects of the invention) According to this invention, the operating lever is accurately guided in the vertical direction, and there is no risk of the operating lever being tilted due to lateral force applied to the operating lever, so piezoelectric The generator can be activated.

In addition, since the arm pieces are L-shaped and are formed facing each other, the arm piece can be pressed to narrow its tip and be easily incorporated into the casing, making it easier to assemble the lighter including the operating lever. becomes easier.

(Embodiment) A preferred embodiment of this invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a lighter body having a fuel tank formed therein, and a cylindrical space 3 opening upward is formed on one side thereof into which a piezoelectric generator 2 can be inserted from above. A columnar electrode stand 4 extending upward is integrally formed approximately at the center of the upper surface of the main body 1 . 5 is a burner nozzle extending from a burner valve device communicating with the inside of the fuel tank, and a lever member 6 is engaged with the burner nozzle.
The piezoelectric generator 2 is a conventionally known device that can generate high voltage by hitting the piezoelectric element with a hammer through the relative operation of a fixed cylindrical body and a movable cylindrical body containing a piezoelectric element and a hammer. It is inserted into the cylindrical space 3 and held in the lighter body 1.
A lead wire 7 extending from the piezoelectric generator 2 is inserted and held in the electrode stand 4, and its tip faces the burner nozzle 5 to constitute a discharge electrode.

A lighter casing 8 is inserted into the lighter body 1 from above, covers the sides and top of the lighter body 1, and is fixed to the lighter body 1 with screws 9. Reference numeral 10 denotes an operating lever linked to the upper end of the piezoelectric generator 2, which is inserted through an opening on one side of the upper part of the lighter casing 8 and is relatively movable up and down. 11 is a metal cover attached to the upper surface of the lighter casing 8,
It has a flame hole 12. 13 is a cover that covers the upper surface of the operating lever 10.

At the top end of the operating lever 10, two L-shaped arm pieces 14, 14 are provided facing each other and extending horizontally. The arm pieces 14, 14 are positioned with a slight gap at the tip of the L-shape, and both arm pieces 14, 1
4 constitutes a substantially rectangular frame shape, the columnar electrode stand 4 is inserted into this frame shape, and the arm piece 14
surrounds and engages with the electrode stand 4. In this way, the arm piece 14 is guided in the vertical direction and moves up and down while engaging with the electrode stand 4, and the control lever 10 is prevented from shifting backward due to the horizontal force applied to the control lever 10. . Also, arm pieces 14, 14
Narrow the lighter casing 8 by the gap at the tip.
The operating lever 10 can be inserted into the interior through the opening, making it easy to assemble the operating lever 10.

On the outer peripheral surface of the cylindrical space 3 into which the piezoelectric generator 2 is inserted, key grooves 15 are vertically formed on both sides and the rear surface, and a key 16 that engages in the key grooves 15 is inserted into the operating lever 10. Formed on the inner surface. Due to the engagement between the keyway 15 and the key 16, the operating lever 10 is accurately guided in the vertical direction.

The keyway 15 and the key 16 can be connected not only on both sides, but also on both sides.
By forming it also on the rear surface, the operating lever 10
The vertical guidance of the lever 10 is more accurately performed, and as a result of the engagement of the three keys with the keyway, the prevention of tilted operation of the operating lever 10 is more reliably achieved.
