Gas lighter

The invention relates to a device for a gas lighter with an ignition lever which can be pivoted horizontally and which is extended Direction of the gas outlet crosses a nozzle »

The purpose of the invention is to create a gas lighter with an ignition lever that can be pivoted horizontally and by a Movement process by means of a light touch of the thumb to be dr.

Another purpose of the invention is to provide a gas lighter with an actuating device that serves as an ignition lever and at its end by means of a pin on the main body of the gas lighter is pivoted. The actuator is pivotable at certain angles to open and ignite an ignition nozzle, which is located in the upper part of the Main body is provided.

Another purpose of the invention is to provide a gas lighter with an ignition lever or actuator hinged to the upper part of the main body and always is closed by the tension of a spring, whereas the actuating device is opened by means of a turning process, which at the same time causes the nozzle to open in order to ignite the gas flowing out of it, after which the actuating device is released against the pressure influence and automatically

table returns to its normal position due to the tension of the! spring.

The invention includes a gas lighter including one Ignition actuator that is stored horizontally and through Rotation is so movable that the extended direction of the specified gas of a nozzle to be ignited is crossed.

The invention is explained in more detail below with reference to the drawings « Show it:

Fig. 1 shows an embodiment of an inventive piezoelectric lighter in actuation position as well as in plan view,

FIG. 2 shows an actuating device contained in the lighter according to FIG. 1, partially broken away Top view representation,

3 shows the lighter according to FIG. 1 in partial vertical section O

An actuator 1 serves as both a cover and a lever which has an open upper part of a main body 7 covers a gas lighter. Below the actuation device as well as on its rear part (left side of the drawing) a cylindrical shaft 1 'is in one piece formed, in which a coil spring and a hold-down piece 3 are inserted «, under the hold-down piece 3 is a Cam 4 mounted, which can be pivoted up and down = an inner surface 4 'of the cam 4 is beveled at its end-

A helical spring 5 is wound around the upper part of the cylindrical shaft 1 '. A hammer-like piece 6 touches the beveled surface 4' of the end section ^{with a head 6 1}

of the cam 4 and is rotatably mounted on a shaft 8, the is held on both walls of the main body 7. A spring 9 is wound around the hammer-like piece in the direction of impact vorzuspanneno A nozzle 10 runs to the open one Top of the main body .7 and stands with a lever 11 engages through which a valve (not shown) is to be moved in the sense of opening and closing. On the inside At the end of the lever Ί1 there is an upstanding bolt 12, the upper part of which is slidingly in contact with a.m beveled cam 13 * of a sliding projection 13 which is inside the The upper part of the actuating device 1 is formed in order to move the upstanding bolt 12 downwards.

A push operating portion 1 ″ of the operating device is provided with a corrugated surface for preventing slippage of the thumb when actuated. Furthermore, a piezoelectric element 14 and an electrode 15 are provided, which is attached at a distance from the other electrode or nozzle 10 »In the space between the two electrodes spark discharge can occur.

A gate 1r is within the actuating device 1 next to the cylindrical shaft 1 'at a distance and opposite one another arranged for this purpose and able to come into contact with a stop 1s, which is on the upper surface of the main body is designed to produce a rotation limitation of the actuating device 1. Along their pressure actuation section 1 ' an edge portion 7r is formed with a recessed Abutment 7s is able to come into contact with the main body 7.

In operation, the push operating section 1 'becomes the operating device 1 of the gas lighter whose main body 7 of Hand is held horizontally by means of the thumb against the Bias of the coil spring 5 rotated around the

cylindrical shaft 1 'of the actuating device 1 or a cover which serves as a lever and pivots around "until the projection 1r rests against the stop 1s of the main body 7, while the cam 4 ·, which is pivotable on the cylindrical shaft 1' is rotated so that its end section ^{strikes the head 6 1 of} the hammer 6. Its end section moves upwards against the bias of the spring 9, with a rotation around the shaft 8, as shown in FIG is illustrated.

At the moment when the end portion of the cam 4 passes over the head 6 ', i. h = when the end section of the cam '4-is released from the contact opposite the head 6 ¹ , the hammer 6 returns to the normal position by the tension of the spring 9 and strikes against the piezoelectric element 14- to generate electricity and a discharge between electrode 15 and the upper part of the nozzle 10 =

When the actuating device 1 or a cover serving as a lever rotates, the protruding bolt 12 is touched its upper part with the beveled cam 13 'of the GleitvorSprunges 13 on the lever 1 is depressed to one Depressing the end portion of the lever 11 to open and close a valve at the same time; the other section of the lever lifts the nozzle 10, opening the valve to vent gaseous fuel, which in more efficient Way is ignited by the electrical discharge.

When the pressure operating section 1 ″ is released from the pressing action of the thumb, which means that the rotation is influenced is removed from the actuating device 1, the device 1 reverses by the tension of the spring automatically returns to the normal position when the edge part 7r rests against the recessed stop 7s «

When the actuator 1 returns, the cam 4 is moved back to the position in which the inclined inside surface 4- 'of the cam 4 ^{slides smoothly over the head 6 1 of} the hammer 6 so that the hammer 6 is not pushed by the cam 4 is operated, which is rotated around the shaft, as shown in Fig = 3 is illustrated.

During the return process of the actuating device 1, the protruding bolt 9 is also opposed to a low pressure of the beveled cam 13 ^! of the sliding projection 13 released, whereby the lever 11 for opening and closing the valve returns to the normal position by means of a suitable leather (not illustrated) in order to close the nozzle 10 and stop the delivery of gaseous fuel »

By repeating the above-mentioned process, the ignition process is achieved in this way »

As mentioned above, in the present embodiment the actuating device 1 to operate, since both a cover and a lever on the upper opening of the Main body 7 of the gas lighter are arranged, which are pivoted and horizontally cross the extended direction of the upward gas discharge from a nozzle.

In another embodiment, however, the actuating device be located in a central part of the main body of the gas lighter or in the ignition system instead the impact process of the piezoelectric element can an ignition system known per se in the form of an ignition friction surface, an electric filament or a discharge system for actuation by pressure can also be provided; instead of the device for opening and closing the valve in connection with the ignition nozzle 10 can have another modified con-

"instruction should be provided.

According to the invention it is achieved that only a gentle touch of the thumb is required during operation, because the subject of the invention is constructed more simply than other known gas lighters »The required gentle touch is none known gas lighter own, but rather these require a strong finger pressure during the ignition process o The simple one Structure of the subject matter of the invention facilitates its production in large numbers at low costs.
