PATENT SPECIFICATION
( 11) 1 574 802 ( 21) Application No 19406/76 ( 22) Filed 11 May 1976 ( 23) Complete Specification Filed 4 May 1977 ( 44) Complete Specification Published 10 Sep 1980 ( 51) INT CL 3 F 23 Q 2/28 ( 52) Index at Acceptance F 4 F 3 B 3 F 3 H 3 J 9 DX 9 EY ( 72) Inventor: HANS LOWENTHAL ( 54) SMOKERS’ LIGHTER ( 71) We, COLIBRI LIGHTERS LIMITED, a British Company, of Colibri House, 69 Warren Street, London, W 1 P 6 AD, do hereby declare the invention, for which we pray that a patent may be granted to us and the method by which it is to be performed, to be particularly described in
and by the following statement:-
The invention relates to a smokers’ lighter of the so called “box-type”, that is the type having a substantially rectangular casing of elongate horizontal cross section and the upper part of which is constituted by a lid which is connected to the remainder of the casing so that the lid may be swung upwards generally adjacent to a narrower edge In order to operate the lighter the lid is first swung upwards to expose the burner, after which an actuating member is actuated manually to operate an ignition system.
Modern lighters are gas burning and the predominant trend for some fifteen years has been for the gas to be ignited by a discharge adjacent to the burner of an electric spark derived either from a piezo electric unit or from a battery energised circuit within the lighter In a box-type lighter the raising of the lid conventionally opens the gas valve and the electrical ignition system is then operated by actuating a piezo electric mechanism, or a button or other switch member in the case of a battery energised circuit It has been customary for these actuating members to be adjacent to the narrower edge of the lighter remote from the lid hinge, particularly when, to avoid accidental operation of the ignition system, the actuating member is only exposed for operation or made operational when the lid has been raised This positioning of the actuating member has been inconvenient It requires the burner to be situated nearer to the lid hinge and hence adjacent to the lid so that the flame is not as readily accessible for use as would be desirable, or the actuating linkage has to by-pass the gas tank or burner valve.
In accordance with the present invention, a gas burning smokers’ lighter of the boxtype has a substantially rectangular casing of elongate horizontal cross section, with an upper part of the casing constituted by a lid, and means connecting the lid to the casing whereby the lid may be swung upwards generally adjacent to a narrower edge thereof; a fuel reservoir tank having a burner at the upper end thereof and positioned within the casing adjacent to the narrower edge of the casing remote from the edge about which the lid swings upwards whereby the burner is exposed upon upward swinging of the lid; and an electric spark ignition unit having an actuating member adjacent to the upper end thereof and positioned side by side with the fuel reservoir tank in the casing and adjacent to the narrower edge of the lighter casing about which the lid swings upwards, the actuating member being shaped and arranged to be drawn downwards by an operator’s thumb applied at a broader side of the casing to operate the spark ignition unit, and at least that part of the actuating member which is arranged to be contacted by the operator’s thumb only being accessible upon raising of the lid.
With this construction the lighter can be operated by applying the operator’s thumb to the actuating member at the broader side of the lighter at a position, as seen perpendicularly to the broader side of the lighter, generally spaced between the burner and the lid The flame is then produced at the narrower edge of the lighter remote from the lid where it is most useful for application to a cigarette or pipe to be lit and the burner valve mechanism and ignition system can be distinct and separate.
Inadvertant actuation of the ignition system is effectively precluded as at least that part of the actuating member which cl IT ( 19) 1 574 802 must be contacted by the operator to operate the ignition system is only exposed and accessible after raising of the lid Indeed for aesthetic reasons the actuating member may be concealed when the lid is closed.
The lid is preferably shaped on a broader side of the lighter casing to facilitate the raising of the lid by an operator’s thumb.
This is particularly useful when the lighter is capable of being operated only at one broader side in which case the shaping will preferably be unique to that broader side.
The shaping simplifies the complete operation of the lighter by the thumb of the operator’s hand in which the lighter is held, by first raising the lid using the thumb, and subsequently applying the thumb to the actuating member When the shaping is unique to one broader side of the lid at which the actuating member is accessible, it naturally follows that when the lighter is handled, the operator instinctively knows by feel how the lighter should be held so that the lid may be raised and the actuating member readily operated by his thumb The shaping may be a projection or projections, serrations, or a depression or depressions in the side of the lid It may also take the form of a conventional initial shield.
The actuating member may be an actuating plunger of a piezoelectric ignition system In this case the actuating plunger may be broader than would be possible if it were positioned at a narrower side of the casing, thereby resulting in a “softer” feeling.
Alternatively, the actuating member may be connected in a battery energised ignition circuit.
The actuating member, or a separate actuating member, may be used to open the gas burner valve, especially in the case of a piezoelectric ignition system, but preferably the gas burner valve is opened by the operation of raising the lid.
The various features referred to above may be used in any appropriate combination with one another.
The new construction is cheap, simple and reliable, and leads to simple servicing as the actuating member may extend directly from the ignition system.
Some examples of lighters constructed in accordance with the present invention are illustrated in the accompanying drawings in which:Figure 1 is a perspective view of the upper part of one lighter upon operation; Figure 2 is a side elevation of the upper part of the Figure 1 lighter prior to operation; Figure 3 is a diagrammatic side elevation of the Figure 1 lighter showing the lid raised and with the front part of the casing omitted to show the interior parts; Figure 4 is a view similar to Figure 2 but of a second example; Figures 5, 6, and 7 are views similar to Figure 1 to 3 but of a third lighter.
Figure 8 is a perspective view of the upper part of a fourth lighter prior to operation; Figure 9 is a view similar to Figure 8 but showing the lid partially raised; Figure 10 is a view similar to Figures 8 and 9 but showing the lid fully raised and the lighter operated; Figure 11 is a diagrammatic side elevation of the upper part of the Figure 8 lighter with the lid closed; Figure 12 is a view similar to Figure 3 but of the Figure 8 lighter; and, Figure 13 is a diagrammatic section taken on the line XIII-XIII in Figure 12.
The lighter shown in Figures 1 to 3 has, like the other examples, a rectangular box shaped casing comprising a body part 25 and a lid 26 hinged to the body along a narrower edge by a hinge 27 The hinge 27 might replaced by some other form of pivotal connection, such as pivotal links, which causes the lid 26 to swing upwards generally about its narrower edge relatively to the body 25.
The body 25 contains a gaseous fuel reservoir 28 provided with a burner 29 which is exposed when the lid 26 is raised.
Raising of the lid 26 may raise the burner 29 and open a valve to discharge fuel gas through an opening 31 in a block 32 which is exposed upon opening of the lid.
The casing body 25 also houses an impact piezoelectric spark generating unit 41 Such units are well known and will not be described here Upon opening of the lid 26, an actuating member 42 in the form of a serrated plunger is exposed and and ignition spark is produced from the generator 41 by pressing the plunger 42 downwards.
The lid has, uniquely on the broad side visible in the Figures, a depressed initial shield 43 which facilitates raising of the lid by the operator’s thumb.
In the Figure 4 modification, instead of the shield 43, the casing body 25 and lid 26 are each provided with one half of a circular dish-shaped thumb depression 36 which is unique to the broader side of the lighter visible in Figure 4.
In operation the operator holds the casing body 25 in the palm of the hand, applies the thumb to the shield 43 or depression 36 and pushes upwards to raise the lid 26 and open the burner valve The actuating member 42 is only then exposed between the burner and lid and upon depression causes the discharge of a spark between electrodes adjacent to the burner 29 to ignite the flame shown in Figure 1 at 37 It will be appreciated that this flame is adjacent to the narrow side of the lighter remote from the hinge 27 where it is readily accessible for use.
1 574 802 The third example illustrated in Figures 5 to 7, is similar to the first example and analogous parts are given similar reference numerals in this and the subsequent examples A spark generator 49 energised by a 1.5 volt battery 33 is used to produce the ignition spark and is operated upon depression of a plunger 50 which is partly exposed at all times in a slot 51 in the upper edge of the casing body 25 but which is not fully exposed so that a downward pressure can be applied to operate the unit 49, until the lid 26 has been raised Upon depression the plunger 50 closes a switch which operates the spark generator and causes the discharge of an ignition spark adjacent to the burner 29 The spark generating unit incorporates conventional circuitry which need not be described here In this example the broader side of the lid, which is visible in Figures 5 and 6 is flared outwards to provide an overhang 52 to facilitate raising of the lid by the operator’s thumb.
The fourth example illustrated in Figures 8 to 13 is provided with a conventional impact piezoelectric spark generating unit 53 which is operated by depression of a serrated actuating member 54 The actuating member 54 is only exposed when the lid 26 is opened and is pivotally mounted about a hinge 55 A compression spring 56 acts on a portion of the actuating member below the hinge 55 tending to urge the serrated part of the actuating member to the left as seen in Figure 13, that is into the confines of the casing When the lid is open, the lid causes a cam member 57 to swing upwards, and ride over a surface of the actuating member, causing it to pivot against the action of the spring 56, from the Figure 9 to the Figures and 13 position, in which it overhangs the broader side of the casing body 25 and is more readily accessible for application of the operator’s thumb In this example the lid is provided uniquely on the operating broader side with a rectangular initial shield projection 58 for facilitating opening of the lid by the operator’s thumb.
