Description

Safety lighter with rotary wheel hood {A Safety Lighter With Rotary Wheel Hoods}

The present invention relates to the lighter field, and to a cigarette lighter. The present invention more particularly relates to a safety lighter having a rotating striker wheel.

US Pat. No. 5,769,625, incorporated herein by reference for all purposes, discloses the state of the technical safety lighter with an improved striker wheel and scriber wheel mounting frame. The lighter has an igniter with a striker wheel that rotates about an axis in response to a force exerted by the user's finger on the wheel. The annular concave central portion of the outer annular surface of the striker wheel has protrusions (or grooves formed therein) on it, while the annular non-concave side portion of the outer annular surface of the striker wheel is smooth. Moreover, the striker wheel is mounted in the groove in the lighter. The striker wheel has a second spring with sufficient spring force to cause the lighter flint to spark when the striker wheel is rotated, from a first position having insufficient spring force to cause the lighter flint to spark when the striker wheel is rotated. Is pressed to the position of.

While pressing the striker wheel from the first position to the second position is an effective safety mechanism, the present invention provides an improvement by rotating the rotary striker wheel in the same position and rotating about the same horizontal axis. In the present invention, the striker wheel does not vertically displace. Rather, the present invention uses a rotating hood, which displaces the rotational motion from the first position to the second position to engage the outer edge of the striker wheel to ignite the lighter by translating the rotational movement to the wheel.

The present invention is a lighter with an igniter having a striker wheel that rotates about an axis in response to a force applied to the wheel by a user's thumb (or any other finger or hand portion). The striker wheel has an outer annular surface with an annular concave center portion and an annular non-concave side portion.

The annular recess has a rough surface with protrusions formed therein (or grooves formed therein). The annular non-concave side portion of the striker wheel may be smooth or have protrusions thereon, depending on the embodiment.

Rotary wheel hoods circumferentially surround the annular, non-concave side portions of the striker wheel. The hood has an inner and outer annular surface. The hood also has a central opening formed therethrough to rotatably receive the central axis of the striker wheel. The central opening has a diameter larger than the diameter of the central axis. Thus, the rotary wheel hood has a rotational motion applied to the striker wheel from a first position where the inner surface of the hood is not in contact with the striker wheel, with the inner surface of the hood engaged with the striker wheel along an annular non-concave side portion. The second position can cause a spark. When the igniter works, the spark ignites the lighter. The inner and outer surfaces of the hood may again be smooth or have protrusions thereon, depending on the embodiments of the invention.

Preferred embodiments of the present invention are shown in the drawings referenced herein. Like reference numerals will be used to identify like elements throughout the drawings.

1A-1C show components commonly mounted on a lighter body 601, including lighter fuel. Such components include a nozzle 608 having a downwardly extending tube disposed toward the front of the head and lighter body 601, a flame control wheel 607, and a thumb control actuator 615 connected to the flame control wheel. ), An igniter having a mounting frame 614, a windscreen 621, a nozzle actuating lever 616, a spring 617, a lighter stone 618, and a striker wheel 620.

As mentioned above, the tube of the nozzle is connected in communication with the inside of the lighter body in which fuel is stored. The nozzle can move from the lower position to the upper position. When the nozzle is in the lower position, fuel cannot be discharged from it. When the nozzle is in the upper position, fuel is discharged therefrom. In normal operation, the striker wheel of the lighter is rotated and the rear of the lever 616 is pressurized substantially simultaneously, causing the nozzle to be raised and sparking when the teeth of the striker wheel rub against and engage the lighter stone 618. do. The spark ignites the fuel and the flame is maintained as long as the rear of the lever is kept pressed downwards.

The frame 614 is mounted on the lighter body with the hollow frame stem 614d inserted in the hole 601a of the lighter body. The nozzle action lever 616 is mounted on the frame with the pivot 616a inserted in the groove 614b. The striker wheel 620 is formed in the shape of a wheel with an annular central portion 619 of the outer annular surface concave with respect to the annular side portion 620a of the outer annular surface of the striker wheel. The striker wheel is mounted on the frame 614 with the shaft 620b of the wheel fitted in the hole 614c. The lighter stone 618 and the lighter stone spring 617 are mounted in a conventional manner to force the lighter stone 618 towards the projection 619a disposed on the annular concave surface 619 of the striker wheel. It is mounted in the hole 614a.

The projections 619a of the annular concave central portion 619 are a series of toothed teeth, each having a first surface substantially perpendicular to the circular tangent from which the projections extend. The first surface faces clockwise when the lighter is viewed from the side shown in FIG. 4aa. Each tooth also has a second surface, which is inclined toward the counterclockwise direction of the wheel when viewed from the side with the front (or nozzle) end of the lighter towards the left as shown in FIG. 4A.

1A-1C show that the same general apparatus can be used in each embodiment of the present invention. The main difference in each embodiment relates to the rotary wheel hood 922 and the annular non-concave side portion 620a of the striker wheel 620.

Referring now to the rotary wheel hood 922 of the present invention, it can be understood that the hood is a cap such as a cap circumferentially surrounding the annular non-concave side portion 620a of the striker wheel 620. The hood has an inner 922d and an annular surface of the outer 922c. Each hood has a central shaft opening 922a formed therethrough to rotatably receive the central shaft 620b of the striker wheel. The diameter of the shaft opening 922a is larger than the diameter of the shaft 620b. Moreover, the inner diameter d _i of the rotary wheel hood 922 is larger than the diameter d _w of the annular non-concave side portion 620a of the striker wheel 620. Thus, striker wheel 620 cannot be operated or rotated even if rotary wheel hood 922 is rotated. The striker wheel 620 can be rotated about its axis 620b only by rotating the hood while simultaneously pressing or forcing downward on the outer annular surface 922c of the hood 922.

As can be appreciated in the various figures, the inner annular surface 922d can be smooth or have protrusions thereon. In the same manner, the outer annular surface 922c may be smooth or have protrusions thereon. Likewise, the annular non-concave side portion 620a of the striker wheel 620 may have a protrusion (apparatus b, FIG. 1A) or may be smooth (apparatus a, FIG. 1A).

1A shows the inner and outer annular surfaces of the hood 922 as smooth, but the annular non-concave side portions 620a of the striker wheel 620 may be smooth (b) or projecting (a). Can have The magnitude of the pressure that must be applied to the hood 922 to cause the striker wheel 620 to rotate is the smoothness of the hood's protruding surface and the protruding surface of the annular non-concave side portion 620a of the striker wheel 620. Depending on the placement of the smoothness will vary.

1B shows a hood 922 with a smooth inner surface 922d and an outer surface 922c with protrusions. Again, the striker wheel is shown as having a protrusion in device a, while in device b this non-concave side portion 620a is shown as smooth. Lighter stone 618 and spring 617 are assembled in hole 614a of the mounting frame. Under the action of the spring 617, the upper end of the lighter stone 618 is forced against the lower side of the recessed portion 619 of the striker wheel 620. In this first position, if the child rotates the outer surface 922c of the hood 922 clockwise, the diameter of the shaft opening 922a of the hood 922 is greater than the diameter of the shaft 620a, and the hood ( Only the hood 922 will rotate because the inner diameter d _i of 922 is larger than the diameter d _w of the annular non-concave side portion 620a, while the striker wheel 620 will not rotate. .

1C has a protrusion on the annular inner surface 922d and the annular outer surface 922c shows a smooth hood 922. Device (a) of striker wheel 620 represents a side portion with a protrusion and device (b) represents a smooth side portion. Without pressure forcing downward, operation in the first position of the hood is as shown in FIGS. 1A and 1B.

2A-2C show detailed portions of the upper portion of the lighter of FIGS. 1A-1C, respectively, and more clearly show features of the design of the hood 922. Operation has been described previously.

FIG. 3aa shows an assembled detailed perspective view of a portion of the lighter shown in FIG. 2A (apparatus (a)), which is a smooth outer hood surface 922c, a smooth inner hood surface 922a, and a striker wheel 620 Protruding portion of the annular non-concave side portion 620a. Also shown is frame 614 and ignition lever 616. FIG. 3ab shows an assembled detailed perspective view of a portion of the lighter shown in FIG. 2a (apparatus (b)), which is a smooth outer hood surface 922c, a smooth inner hood surface 922a, and a striker wheel 620 Showing a smooth surface on the annular non-concave side portion 620a.

3bb corresponds to device 2a of FIG. 2b as pointed out above, and FIG. 3bb corresponds to device b of FIG. 2b. FIG. 3C corresponds to FIG. 2C (device (a)) as pointed out above, and FIG. 3CB corresponds to device (B) of FIG. 2C.

4A and 4A; 4ba and 4ca; And FIG. 4ca and FIG. 4cb are FIGS. 3aa and 3ab; 3ba and 3ba; And partial side views of the features of the present invention shown in FIGS. 3ca and 3cb, respectively. It should be noted that in this partial side view no downward pressure is applied to the hood 922. The figure simply shows that the shaft 620b is smaller in diameter than the shaft opening 922a so that the hood can be freely rotated without causing the striker wheel 620 to rotate. The inner surface 922d of the hood is not forced against the annular non-concave side portion 620a of the striker wheel 620. Lighter stone 618 may be shown to be pressed against striker wheel 620 as a result of the compressive force of spring 617. Nozzle 608 and lever 616 are also shown.

4A-6C illustrate the action of the safety lighter of the present invention in the second operating position. Reference sign P indicates that a downward force vector is applied to the annular outer surface 922c of the hood 922. 5A to 5CB are detailed perspective views respectively corresponding to FIGS. 3AA to 3CB, but show the application of the pressure P. FIGS. Figures 6aa-6cb are partial side views, respectively, illustrating the features of the design of Figures 3aa-3cb as partially broken cross-sections, showing that pressure is applied to the rotary wheel hood.

To ignite the flame, it is necessary to rotate the hood clockwise while simultaneously pressing downward on the annular outer surface 922c of the rotary wheel hood 922. As a result of the downward force vector on the hood, the annular inner surface 922d of the hood 922 moves to the second position and is forced against the annular non-concave side portion 620a of the striker wheel 620. . Striker wheel 620 will rotate relative to lighter stone 618 in this second position to generate sparks. Simultaneous action of the pressure lever 616 raises the nozzle 608 to release the gas, causing the flame to ignite. The release of pressure on the hood may cause them to return to the first safe position, which is dislodged from the non-concave side portion of the striker wheel as shown in FIGS.

Unique safety lighters have been described above. Various changes in details, materials, apparatus, and uses of components described and illustrated herein to illustrate features of the present invention will be made possible by those of ordinary skill in the art upon reading this disclosure, Such changes are intended to be included within the spirit and scope of the present invention.

The present invention is useful for lighters, and especially prevents the occurrence of fire.
