Definitions

  • the present invention relates to a cigarette lighter using liquefied combustible gas as fuel wherein the quan-.
  • tity of discharge fiow of the liquefied gas in a tank from a burner is adapted to be controlled by moving axially up and down a hollow movable valve member being formed at its upper end with the burner thereof.
  • a hollow movable valve member is screw threaded in the inner periphery of a blinded cylindrical sleeve extending with its bottom portion into the tank, and the upper part of the hollow movable valve member projecting upwardly beyond the opening of the cylindrical sleeve.
  • An operating ring is attached on the valve member by means of a spring washer or the like. By turning the operating ring, the movable valve member is moved up and down within the sleeve. Accordingly, a venting member consisting of a resilient pad member contained at the bottom portion of the sleeve is compressed or is released from the pressure thereof, so as to control the quantity of discharge flow of gas through the movable valve member.
  • the operating ring is moved up and down accompanied with the up and down movement of the movable valve member.
  • the operating ring owing to the position of this operating ring on the end of the tank, when the upward movement of the movable valve member is effected for increasing a flux of gas by releasing the pressure of the ventilating member, the operating ring produces an unpleasant noise due to play in an upward and a downward direction between the tank and the spring washer which is attached to the movable valve member to avoid the upward removement' of the operating ring.
  • the movable valve member is lowered for reducing the flux of gas, the operating ring is in contact with the wall of the tank, and finally the operating ring cannot be turned for a further lowering movement of the movable valve member.
  • a part of periphery of the operating ring may be overhung outwardly to form a stopper.
  • the operating ring may be operated in such a manner that it cannot be turned except within a range of impacting with the front end of a wall of abearing provided on both sides of the wall of the tank.
  • the allowable capacity for turning of the operating ring, determined by the stopper and the wall of the bearing is not attained for one revolution, and consequently the control range for discharge gas flux is limited to a small range and it cannot be controlled above that limited range.
  • one object of the present invention to provide a cigarette lighter which avoids the disadvantages of the known apparatus. It is another object of the present invention to provide a construction of a cigarette lighter in which even when the allowable capacity for turning the operating ring is determined, the movable valve member is adapted to be moved above the limited range so as to control freely the discharge of the gas flux. Incidentally, even upon moving upwardly the movable valve member, the operating ring does not engage the wall of the tank, and also even upon lowering the movable valve member, the operating ring is not urged strongly against the wall of the tank to such a degree, that it cannot be turned.
  • FIG. 1 is a longitudinal sectional view of the flux control deviceof the gas lighter
  • FIG. 2 is a longitudinal sectional view similar to that shown in FIG. 1, yet in a different working position
  • FIG. 3 is a top plan view of the device shown in FIG. 1, parts being broken away for better demonstration,
  • FIG.'4 is a longitudinal sectional view of an essential part of a gas lighter disclosing another embodiment thereof.
  • FIGS. 5 and 6 are longitudinal sectional views of the embodiment shown in FIG. 4 in different operative positions
  • FIG. 7 is a top plan view, partly broken away, of the embodiment disclosed in FIG. 4,
  • FIG. 8 is a longitudinal sectional view of an essential part of a gas lighter, disclosing a third embodiment thereof,
  • a valve cylinder b is fitted at its open end to the wall of the tank a and projected into the tank a at its major part.
  • a movable valve member screw 0 is threaded into the inner periphery of the valve cylinder b.
  • a through hole 1 is disposed at the bottom face of the valve cylinder b to provide a communication with the tank a.
  • a resilientmember 2 having a central hole 2,, which is aligned with the hole 1, is received in the valve cylinder b.
  • a passage 3 is disposed in axial direction in the movable valve members, and the upper end opening of the passage 3 forms a burner 4.
  • splines 5 are formed longitudinally.
  • An operating ring d has at its central part of the bottom of a reaccessed part 6 splines 7, disposed in a central hole thereof and in engagement with the splines 5 of the valve member 0. Consequently, when the operating ring d is brought into engagement from the side of the burner 4 with the movable valve member 0 and also brings about engagement of the splines 7 with the splines 5, the injecting gas quantity can be adjusted through the operating ring d by the movable valve member c.
  • a pawl 8 is formed on the operating ring d by cutting and bending outwardly along its downward peripheral wall.
  • the operating ring d can be turned within a range impacting the pawl 8 with the side wall 7 of a bearing of a burner cover e provided on tank a.
  • a coil spring 9 is contained in the recessed part 6 and the coil spring 9 is prevented from a further lifting or fall. ing off by means of a Washer 11 and a washer spring 10 which is mounted on an upper part of the movable valve member 0.
  • the washer 11 supports the upper part of the coil spring 9 in its compressed state. In this state, the operating ring d is lowered until its downward peripheral wall is in contact with the upper part of the tank a, or until the bottom surface of the recessed part 6 engages the upper end of the valve cylinder b, and the spline 7 are held in engaging relation with the splines 5.
  • the washer 11 is dimensioned such as to enter slightly into the recessed part 6 and the spring washer 10 serves to hold the washer 11 at the same level as the upper surface of the recessed part 6, so as to improve the external appearance of all the parts.
  • the other end of the coil spring 9 engages the outer bottom surface of the recessed part 6.
  • the operating ring d can be turned freely without engaging the movable valve member c, when the splines 7 are released from the splines 5, by lifting the operating ring d, so as to compress the coil spring 9 as shown in FIG. 2.
  • the operating ring d is always held by means of the coil spring 9 to engage the movable valve member c, and consequently any play on the operating ring d or any heavy turning of the operating ring d can be eliminated entirely, notwithstanding the ascent and descent of the movable valve member c.
  • the above fact is a true matter in either case of using a freely turnable operating ring or using a definite range turnable operating ring, especially in the latter case the operating ring may be turned. by lifting once the operating ring against the action of the coil spring so as to release it from the engagement with the movable valve member and then by lowering it to obtain a fresh engagement with the movable valve memher. In such latter case, the movable valve member of course can be turned over a limited definite range.
  • a tank a contains compressed and liquefied combustible gas.
  • a valve cylinder b is fitted at its open end to the wall of the tank a and projects into the tank a at its major part.
  • a movable valve member screw c threaded into the inner periphery of the valve cylinder b is attached thereto in axial direction.
  • a through hole 1 is provided at the bottom face of the valve cylinder b in communication with the tank a.
  • a resilient member 2' having a central hole 2,, which is aligned with the hole 1 is received in the valve cylinder b.
  • a passage 3' is provided in axial direction in the movable valve member c, and the upper end of the passage 3' forms a burner 4'.
  • splines 5 are formed longitudinally.
  • An operating ring d has at its central part a recessed part 6.
  • splines 7 form a hole and engage the splines 5, and consequently when the operating ring d is inserted from the side of the burner 4' over the movable valve member 0' an engagement is brought about of the splines 7' with the splines 5', the injecting gas quantity can be adjusted through the operating ring d by the movable valve member c'.
  • a pawl 8' is formed from the operating ring :1, by cutting and bending outwardly along its downward peripheral wall.
  • the operating ring d can be turned within a range impacting the pawl 8' with the side wall 1" of a bearing of a burner cover e provided on the tank a.
  • An annular groove 9, is formed on the upper periphery of the movable valve member 0' so as to engage a washer 10' which is broken away a part of its periphery, and, thereby, the falling oti of a washer 11' fitted to the movable valve member 0' is prevented.
  • a fitting cavity 12' for embedding the washer 10' is formed in the washer 11.
  • the washer 10' is fitted in the fitting cavity 12' in such manner that the washer 11' is pressed upwardly by means of a coil spring 9 and splines 7' formed in the hole of the bottom part of the operating ring d engage the splines 5 formed on the movable valve member c.
  • the external periphery of the washer 11' is formed with a downward skirt 11 and consequently the washer 11' can be moved axially in the recessed part 6' of the operating ring d without distortion.
  • the movable valve member c can be turned over a definite limit in which the pawl 8 of the operating ring d impacts with a side wall f of a bearing for controlling the dis charge gas fiux injecting from the burner 4'.
  • the operating ring d is lifted against the action of the spring 9', so as to release the engagement of the splines 7' and 5', and the operating ring d can be turned freely relative to the movable valve member 0'.
  • the operating ring d when the operating ring d is released, to be restored into its original position, the operating ring d is lowered by the extending action of the coil spring 9 and the splines 7' engage the splines 5, and consequently the discharge gas flux can be adjusted over the definite limitation by a further turning of the operating ring. Further, in this assembling, the operating ring d, the coil spring 9 and the washer 11' are inserted and fitted from the side of the burner 4' into this lighter in the order as above mentioned and then the washer 11' is forced into the recessed part 6', so as to compress the coil spring 9', and, thereafter, the washer 10' may be fitted into the annular groove 9
  • the above assembly of all the parts is effected in a very simple manner.
  • the washer 10' does not fall off entirely. Further, if any difiiculty in the operation arises, or when cleaning is necessary, the reverse operation of the above assembling operation may be effected very easily.
  • splines 5' and splines 7 are formed, respectively, on an inner central hole of the operating ring d and on the outer periphery of the washer 11 Accordingly, when the operating ring d is turned in a predetermined direction, the movable valve member c is moved in axial direction.
  • Other parts of this embodiment are the same as those shown in the first and second embodiments, and the operation of the third embodiment is substantially the same. Accord ingly, the same numerals with an index 2 have been applied to the corresponding elements.
