Various gas lighters have already become known, their either built-in or Exchangeable gas container inserted in the lighter housing with a spring force in the closed position held, but when the valve tappet is lifted reveal the gas outlet valve.

In a very simple type of gas lighters in its construction, the lifting of the Valve tappet with the help of a rigidly attached to the free end of the lifting disc, which when you open the Lighter lid of an actuator participating in its movement, ζ. B. one at the rear Cover end arranged nose, gripped under and thus moved upwards together with the valve tappet will. Since the movement of the lifting disc is directly dependent on that of the lid or that located on it Actuator is derived, the cooperating parts must with respect to their mutual Position and trajectories must be precisely coordinated with one another in order to ensure the ignition to achieve the required opening of the gas outlet valve of the escaping gas, but this is often not the case is. No provision has been made for regulating the height of the flame, and only would be accessible with the help of a key or a turntable attached to the gas outlet valve.

More and more lighters between the lifting disc and the their associated actuator interposed a pivot lever acting as a non-equal arm lever to have. In various designs proposed in this regard, the elongated Swivel lever loosely inserted in the lighter and z. B. supported on the fuel tank. Such Lighters have the disadvantage that when changing the gas container, the lighter partially dismantled and then reassembled. In particular, reaching around the liftable Valve stem with the fork-like end of the pivot lever with simultaneous attention its correct position in the lighter proves itself here as well as with the factory-made one Assembling the lighter as time consuming and tedious.

According to another proposal, the elongated pivot lever is permanently attached to the fuel container and thus remains united with it even when it is pulled out. This not only requires the special construction of the fuel container to create a bearing located on it but to the side of the valve stem, but also the special construction of the entire gas lighter with one out of the housing

Lighter so that the pivot lever is brought into the active area of its actuating member located on the lid when the fuel container is inserted can be.

The subject of the invention now forms a gas lighter with a gas container that can be pulled out of the housing, which eliminates the aforementioned disadvantages of all known lighters in that the swivel lever, which is connected to a support shoulder of the valve tappet for the purpose of opening the gas discharge valve cooperates, is formed essentially rotationally symmetrical and is held centrally on the valve stem. The novel swivel lever construction can be used with any type of lighters and attach to any gas container, regardless of whether the ignition device is on the side of the Gas container or above it is arranged in the lid part or with the flint tube in the Gas container reaches into it. This has the advantage that the pivot lever because of its rotationally symmetrical Shape, even if it is freely rotatable around the valve stem, is equally effective in every position. If the gas container also has a cylindrical or prismatic cross-sectional shape, it can, without to have to pay attention to a certain position of the same to be inserted into the lighter housing, itself when the pivot lever with the height-adjustable part of the gas throttle member is rotating

The gas lighter according to FIG. 1 has a joint but the pivot lever with its opposite housing 1, which consists of a housing jacket 2, 3 ° supports the end on a shoulder 28 of the housing, a tiltable lighter lid 3 and an ignition it acts like a one-armed lever, its middle stone device 4 exists. The housing jacket 2 has an area with the support shoulder 25 of the valve in the form of a bent, length shaft 23 cooperating, lifting it and gradually opening sheet metal at the two end faces, thus opening the gas outlet valve 23. The shoulder 28 of the cylinder, along the longitudinal edges of which pairs of flaps 35 are provided by an inwardly protruding tongue of one (not shown), of which the resilient, hook-shaped sheet metal flap 29 is formed, carries an uppermost axle bolt 5 around which one of the underneath one in the housing jacket 2 is provided -Friction wheel 6 rotatable and the lighter lid 3 Mpp- nen opening 30 is attached to it and is with a bar. The mounting of the lighter lid 3 takes place from this opening 30 protruding crank 31 by means of two bent at right angles, 4 ° to each other in the downwardly inclined tongue 28 merges. Around parallel leg 7. On the inside of the cover the cylindrical housing jacket 2 is attached to the outside in a driver 8 which, when the area of the opening 30 is opened, a conical ring 32 of the lighter can be rotatably displaced with the friction wheel 6,
bound driving wheel 9 engages. If the latter is shifted downwards, a second pair of flaps of the housing jacket 2 presses 45 he holds the flint tube 10, which contains a flint crank 31 of the sheet metal flap 29 and thus also 11 and a spring 12 pressing on it. The tongue 28 thereof, increasingly further towards the free end of the flint spring 12, is supported towards the inside. As a result of the downwardly inclined course, an L-shaped slide 13, which is guided in a white tongue 28, the support point of the failed pair of flaps. This slide 13 50 ben-shaped pivot lever 26 on this tongue around will shift the flint spring 12 so higher in the tensioned state, the further it is pressed inwardly held by a housing part 14, which is also held. This results in the possibility of being able to pivot about the axle bolt 5 and the sliding aid of the height-adjustable ring 32 which engages under 13. In the area of the lowest flap pair of angles that results when the lighter is actuated, a transverse wall 15 is arranged, through the 55 deflection of which the pivot lever 26 can be changed so that a central opening is inserted through the lower end of the flint - more or less strong lifting of the valve tube 10 and held in place . Shank 23 to cause and thus the flame against the transverse wall 15 is based on a toggle spring to regulate height. If the gas container 20 is to be removed from the flint tube 10, which surrounds the flint tube 10 and is also to be changed, the upper end of the ring 32 is displaced upwards with the web 17 of a bracket 18 60, whereby the tongue 28 interacts freely. For this purpose, the web 17 has an opening which can spring back as soon as the container has a voltage through which the flint tube 10 passes. its pivot lever 26 out of the housing - two parallel arms 19 of the bracket 18 grip eccentrically and the latter slides over the tongue 28, trisch on the legs 7 of the lighter lid 3 The same occurs when inserting the gas container. and transfer the same automatically into the open 65 As can be seen from FIG. Closed position, as soon as the movement in one speed, the degree of opening of the gas outlet valve or another direction initiated by hand in another way, namely by changing the. mutual distance between the rest position

located disc-shaped pivot lever 26 and the support shoulder 25 a of the valve stem 23 α to adjust.

For this purpose, the support shoulder 25 a is designed in a known manner in the form of a nut, which on the valve stem 23, which is provided with a thread 33 at its upper end, can be screwed. At the When the pressure nose becomes effective, the pivot lever 26 is supported here directly on the raised one Part of the ceiling of the gas container 20.

According to the in F i g. 3 construction shown, the pivot lever for the purpose of flame regulation is given a different angle deflection by the fact that the entire gas container 20 a including the disc-shaped pivot lever is adjusted within the lighter housing according to the height, whereby the pivot lever sooner or later comes into the range of motion of the pressure nose. For this purpose, the housing jacket 2 α and the gas container 20 a are each provided with a thread 34, 34 'in their lower region and can thus be screwed against one another.

According to FIG. 4 is the actuating member for the disk-shaped pivot lever forming the pressure lug 27 c on one of the spring-loaded and pivotable arm beyond its tilted position. 19 of the bracket 18 is provided, which contributes to the transfer of the lighter lid 3 into its open and closed position (see. Fig. 1). Each of the two arms 19 can also be provided with a pressure lug 27c. This arrangement of the pressure lugs or lugs 27c has the advantage that the forces occurring when the pivot lever is actuated do not additionally load the bearing points provided between the arms 19 and the lighter lid 3. Between a disk-shaped pivot lever part 26 c and the support shoulder 25 c of the liftable valve stem 23 c there is loosely arranged a likewise disk-shaped intermediate member 35 which converts the pivot movement of the lever into the opening movement of the gas discharge valve 22 c and which forms an effective part of the disk-shaped pivot lever, which is thus composed of the disk-shaped part 26 c and the disk-shaped intermediate member 35. As is known per se, the support shoulder 25 c is formed directly from the wall of the hollow valve stem 23 c, in that its upper end is widened in the manner of a hollow rivet. This not only creates a widening outflow opening 36 at the same time, the advantage of which is a more wind-resistant flame, but also the point of application of the pivot lever composed of the two disks 26 c, 35 is moved as close as possible to the geometric axis of the valve stem, which is currently is important in an approximately rotationally symmetrical pivot lever to create the largest possible lever transmission ratio. In addition, there is the possibility of adjusting the necessary play between the support shoulder 25 c and pivot lever 26 c, 35 through the extent of the flanging.

A gas throttle element 37 is combined with the gas outlet valve 22 c in a known manner. The den Valve stem 23 c leading part 38 against which the closing spring 24 c of the gas outlet valve 22 c is supported, is screwed into a cup-like recessed portion 39 of the ceiling of the gas container 20 c. That The lower end of the thus height-adjustable part 38 presses on a pressure plate 40 which has a gas passage opening in the center 41 and a valve seat 42 surrounding it for a closure member 43.

This is designed as an elastic stubble and arranged at the lower end of the valve stem 23 c. Between the pressure plate and the bottom of the also provided with a gas passage opening 44 Cup-like ceiling section 39 throttle bodies 45 are inserted. By screwing the height-adjustable Part 38 can change the pressure on the throttle body and thereby the flowing through Gas volume can be regulated. The gas container 20c has a circular cross section on and can, since the pivot lever consisting of parts 26 c, 35 is also designed as a circular disk is to be inserted into the housing 2 in any position. The height-adjustable one Part 38 of the gas throttle member has in its upper area an external toothing 46, which with a similar internal toothing of the pivot lever part 26 c, leaving the for its pivoting required free play interacts, causing these two parts to rotate are connected to each other. In this case, the flame height is adjusted by adjusting the throttle device 37 achieved in that the pivot lever 26 c automatically while maintaining its pivotability is locked in the lighter housing against rotation and one to be made by hand Rotation of the similar as in Fig. 1 below about the Housing protruding gas container 20 c for height adjustment of the adjustment part of the throttle element 37 is exploited. For locking, the pivot lever 26 c is circumferentially provided with teeth 47, the pressure lug 27 c engages in the gaps in the open position of the lighter. Between Pivoting lever 26 c, 35 and gas container 20 c, a support disk 48 is inserted, which in its circumference Area designed as an annular, edge-like raised support 49 for the pivot lever part 26 c and by means of internal teeth likewise with the height-adjustable part 38 of the gas throttle element 37 is coupled to rotate. To the range of rotation of the gas container 20 c and thus the height adjustment of the part 38, a circumferential shoulder 50 is arranged on the container top, into which a tab 51 bent from the periphery of the support disk protrudes, with a in the paragraph provided stop 52 cooperates.

In Fig. 5 shows a variant of the construction according to FIG. 4, in which the pivot lever part 26 d is not directly coupled to the height-adjustable part 38 of the gas throttle member 37, but surrounds it at a distance in the form of an annular disc. For the non-rotatable connection of the pivot lever part 26 d to the height-adjustable part 38, the support disk 48 d coupled to rotate with the latter is used. For this purpose, it has a number of openings 53 into which lugs 55 which are bent downwards engage along the inner edge 54 of the annular pivot lever part 26 d. A stop 52 d is provided here directly on the ceiling of the gas container 20 d, namely adjacent to the outer edge of the support disk 48 d . This border has a toothed design, and at least one can be used to limit the adjustment range of the gas throttle element 37

1 211 Oil

these teeth 56 as a counter stop in the area of the stop. 52 d can be bent. Characterized in that the bearing point of the pivot lever member 26 is d moved up due to its ring shape closer d to the valve stem 23, results in favorable balance of power, according to which Auflagerscheibe 48 d securely to the ceiling of the gas container 2oD is pressed. Since, moreover, only the support disk 48d, which is not pivoted, engages with the toothing 46 of the height-adjustable part 38 of the gas outlet valve, this toothing need only be formed in a short area, regardless of free play.

In Figs. 6 and 7, the embodiment of a gas lighter is shown in which a downwardly displaced when the lighter is operated and connected to the cover 3 by handlebar 59 engine part 57 has a boom 58, at the end of which as an actuator for the Pivot lever 26 e provided pressure lug 27 e is designed. This accordingly acts from above on the edge part of the rotationally symmetrical pivot lever 26e , which comes to rest between this edge part and its point of application on the support shoulder 25 of the liftable valve stem 23 on part of the gas container 20. To regulate the flame height, for. B. the possibility of making the boom 58 adjustable with respect to the engine part 57 and thereby changing the mutual position between the pivot lever 26 e and the pressure lug 27 e acting on it.

Also in the embodiment according to FIG. 8 and 9, the actuating member 27 / acts from above on the bulged, disk-shaped Swivel lever 26 / a is provided with openings, but this is another precaution for adjusting the flame been hit. For this purpose, the valve stem 23 / a square cross-section; the valve stem 23 / is in a suitable guide of the height-adjustable Part 38 / of the gas outlet valve mounted, whereby these two parts are coupled in rotation are. The pivot lever 26 / is leaving the required for its pivoting movement free play with the valve stem 23 / rotatably connected in the same way. The pivot lever 26 / is circumferentially provided with a toothing 47 /, in which a paragraph when the lighter is operated of the actuator 27 / comes into engagement and thus the pivot lever and subsequently the height-adjustable part 38 / locked against rotation. To adjust the here with one in one Rubber washer 61 pressed wick 62 provided throttle member 37 / the gas container 20 / is locked Swivel lever 26 / rotated in the lighter housing by a corresponding angle.

As can be seen, all the exemplary embodiments shown have the feature in common that the pivoting levers permanently connected to the gas container are essentially rotationally symmetrical and is held centrally on the valve stem, whereby it is when the gas container is inserted into the lighter housing automatically comes into the range of action of the actuator provided on the latter. There are also insignificant deviations of the pivot lever from its rotationally symmetrical shape, e.g. training as any polygon within the scope of the invention.

The constructions described also make it possible in the simplest way to use conventional pyrophoric lighters to be provided with an actuator for the pivot lever and in addition to the Gas tanks to be supplied with gasoline tanks, which means that you can use one or the other fuel is made possible.
