Description

Priority: March 7, 1973; V. St. A, Ser. Ήο. 338 991

The invention "relates to a lighter that is liquid Uses fuel which becomes gaseous at normal temperature and pressure; in particular, the invention relates to such a lighter, which is cheap to manufacture and, when the fuel supply is used up, is thrown away.

Such disposable lighters have been recently become completely customary. It arises with such Lighters do the job of cheap manufacture so it is appropriate to refill the lighter To take distance. Manufacturing cheaper can be achieved by reducing the assembly costs and the costs used

Individual parts.

Accordingly, the invention relates to such a divisible one Lighter that consists of the smallest possible number of individual parts · which themselves are simple and with minimal Workload can be produced ..

A lighter according to the invention, in particular a cigarette lighter, has means for generating sparks and for actuating the gas valve, which can be produced on a plastic Base part are arranged.

409838/0310

Figure 6 shows a cross section according to the section line 6-6 of Figure 5 \

FIG. 7 shows a base part consisting of "pressed plastic" for holding the spark generating unit Friction wheel and flint.

In FIG. 1 and FIG. 2, the lighter as a whole is designated by 10. The lighter 10 has a fuel tank 12, the liquid fuel "F", "for example, butane contains the" at the temperature and pressure of the environment becomes gaseous. The tank 12 has a bottom 14 and side walls 16, for the purpose of simplifying manufacture in the injection molding process, expand towards the open end. The walls 14 and 16 form the lower one Half 18 of the lighter, the pressed upper part 20 being connected to the lower part 18.

As shown in Figure 3 and Figure 4 is a threaded hole 22 in the upper part 23 of the housing 20, which serves as a closure piece of the tank 12, is provided. A well-known gas valve 24 of the piston type is screwed into the bore 22.

In the illustrated embodiment, the piston valve an inner spring. The valve is meanwhile opened and kept closed by a spring preloaded Operating handle. Valves of this type are known, for example shown in U.S. Patents 3,423,160 and 3,063,276.

In the upper part 23 an opening 26 is provided which " connects the bore 22 provided for receiving the valve with the fuel reservoir 12. A wick 28- extends from the reservoir through the opening 26 and

delivers fuel to valve 24.

A second recess 30 is provided in the upper housing part 20 and serves to accommodate the actuation of the spark generator and for lifting the valve serving handle. This handle part consists of a single pressed part 32, which is the carrier of the A spark generating friction wheel that holds the flint and acts as a valve lifter for valve 24. Two im Flanges 34, which are spaced apart from one another and arranged parallel to one another, are arranged going upwards from the upper part 20 and carry the operating handle 32.

Two bearing holes 36 are provided in the flanges 34 and there are essentially vertical wedge-shaped grooves 38, which lead to the openings 36, pressed into the flanges. The part 32 has two axle journals 40, as in FIG. 7 shows and these pins are mounted in the bearing holes 36. The wedge-shaped grooves 38 allow easy Insertion of the pin 40 in that the flexible flanges 34 can spring back and thereby the insertion of the Allow pegs into bearing holes 36; thereafter the flanges spring back to their normal vertical position so that the operating handle 32 is pivotally attached.

A valve lifter 42 is provided on the operating handle 32, which is forked at its end and has an opening 44. The burner tube 46 of the valve 24 passes through it the opening 44, the burner tube having an upper flange 48 and a lower flange 49, so that the bifurcated End of the valve lifter 42 engages between these flanges, which in turn engages the vertical movement of the valve lifter in limit with respect to the burner tube.

GG 3294 - 5 -

The tube 50 containing the flint also forms part of the operating handle 3-2 and a spring 52 engages the tube 50 and holds the flint in the desired position Location.

On the other hand with respect to tube 50 are upwardly extending and parallel and spaced from each other arranged holding flanges 56 for holding the spark generating friction wheel provided inward aligned axle journals 58 have. The one generating the Εμί & βη Friction wheel 60 has a hole 61 in the middle and is brought to snap onto pin 58 so that it can be rotated is mounted on the same and can rub against the flint 54.

The handle part 32 also has a part 62 "which is located in opposite direction to the valve lifter 42 extends.

The Y-valve 24 has a toothed collar 64 which lies above a leaf spring 66. The leaf spring has an opening 88, which is penetrated by the Y-valve 24, but which has a smaller diameter than the collar 64. It will as a result, the spring 66 is held between the collar 24 and the upper part 23. The other end 70 of the spring 66 is free and acts against the underside 72 of the handle part 62.

The opening 30 'in the upper housing part 20 has a plug hole for receiving the spring 52 which acts against the flint 54.

For actuation, the actuating handle 32, which is pressed from one piece, is moved from its rest position shown in FIG the operating position according to Figure 4 moves. This is done alone

in that the thumb is placed on the friction wheel 60 and, in "Figure 3, is rotated clockwise for the purpose of generating sparks. Simultaneously, the Thumb on the handle part 62- to rest and "causes it a rotation of the operating handle 32 about the axle journals 40, which are mounted in the bearing holes 36 of the plansche 34- are. As a result, the valve lifter 42 swings upwards, against the upper surface 48 of the burner tube 46. In the raised Position of the valve 24 can * fuel P, the is in the reservoir, exit through the burner tube in the form of gas. So far the gaseous fuel gets in the way of the spark caused by the abrasive action of the friction wheel are generated on the flint, the gas is ignited and a flame is created. the The flame will burn as long as the handle part 62 is pressed down. When the pinger pressure on the handle part 62 is canceled, the spring 66 acts, in particular its rear end 70 -a rotation of the operating handle 32 counterclockwise and it acts, then the Valve lifter 42 against the lower flange 49 of the burner tube 46. This closes the valve 24 and the The fuel supply from the reservoir 12 is switched off.

A relatively wide recess 30 in the upper housing part 20 allows the flint receiving tube 50 to move back and forth while the plug hole 74 encloses the spring 52 over most of the length.

For protection, a cap 76 is provided which surrounds the upper end of the lighter 10. The cap 76 has an opening 78 through which the flame of the burner tube 46 can pass.

The regulation of the size of the flame depends on the mechanical pressure setting of the valve 24. Such attitudes are generally known and "consist, see FIGS. 5 and 6, of an adjusting lever 80, the-an opening 81 of the cap penetrated and engages in teeth 82 of the collar 64.

The filling of the reservoir 12 with fuel is well known. It can be done in such a way that the valve 24 is opened and fuel is filled under pressure will; an opening can also be provided in the bottom 14 of the reservoir through which the filling can be carried out and which is then closed again. It is that It is up to the manufacturer of the lighter what type of filler should be.

The use of a single pressed operating handle ' 32, which serves a plurality of functions, reduces the cost of the lighter 10 so that it can be used as a throw-away lighter can use.

The main characteristic features of the invention are - that the lighter, consisting of a Brennst off reservoir, a lifting operated Yentil and a pivotable actuating handle that simultaneously acts as a valve lever and carries the friction wheel assembly, is formed from a single pressed part, which the bearing means, the handle to be operated by finger pressure, forms the receiving tube for the flint and the bearing means for the friction wheel.
