Description
BACKGROUND OF THE PRESENT INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to a lighter, and more
particularly to a chip lighter comprising an outer casing and an
actuation mechanism for forming a chip-shaped atheistic appearance
of the lighter.
[0003] 2. Description of Related Arts
[0004] A conventional lighter usually comprises a lighter casing, a
fuel-storage chamber having a gas release nozzle provided in the
lighter casing for storing liquefied gaseous fuel and releasing the
gaseous fuel when the has release nozzle is uplifted, a
piezoelectric unit, and an ignition triggering device.
[0005] The piezoelectric unit comprises a fixed part and a movable
part movably attached thereto wherein when the movable element is
depressed with respect to the fixed element, a piezoelectric spark
will be generated for ignition.
[0006] The ignition triggering device comprises a trigger button
slidably mounted on the lighter casing and operatively communicated
with the piezoelectric unit, and a lever pivotally communicating
the gas release nozzle with the trigger button in such a manner
that when the trigger button is slidably depressed, the lever will
pivotally uplift the gas release nozzle so as to release the
gaseous fuel. Simultaneously, the movable part of the piezoelectric
unit is depressed wherein gaseous fuel coming out from the gas
release nozzle is arranged to be ignited by the piezoelectric spark
generate from the piezoelectric unit.
[0007] A major problem for this kind of conventional lighter is
that it is aesthetically unsound. For example, the lighter casing
is usually elongated in shape having a rectangular cross section,
and is made transparent so that the user can usually observe the
liquefied gas stored in the fuel-storage chamber. As a result,
everyone sees the lighter will know that it is a lighter.
[0008] In some circumstances however, it is not desirable to let
some people know that there is a lighter. For example, when a child
notices that there is an unattended lighter placed on a table, the
child may, driven by curiosity, get that lighter and tries to
ignite it for fun. This is a very dangerous situation when one
realizes that the child may carelessly burn something else or even
his or her body when he or she has access to that lighter. On the
other hand however, since lighters are commonly needed for igniting
a cigarette, people may not be willing to place them in a locked
location because doing so may induce great inconvenience for them
when they wish to smoke.
[0009] As a matter of fact, there exist some lighters which are
specifically shaped for providing a funny aesthetic appearance
thereof. The problem with these lighters however, is that they are
not specifically designed for avoiding recognition thereof so that
although they are designed to have a funny appearance, everyone
(including children) who comes to see the lighter will know that it
is actually a lighter capable of being ignited for generating
fire.
[0010] Another problem for these kinds of lighters is that when
they are designed to possess special aesthetic appearance, they are
usually difficult to be actuated because the actuation button and
the lighter casing may be ergonomically unsound so that the user
may feel inconvenient, uncomfortable, or even tired when they are
using such kind of lighters.
SUMMARY OF THE PRESENT INVENTION
[0011] A main object of the present invention is to provide a
lighter comprising an outer casing and an actuation mechanism for
forming a chip stack aesthetic appearance for enhancing an
actuation of the lighter and at the same time avoiding it from
being recognized as a lighter.
[0012] Another object of the present invention is to provide a
lighter which is actuated by sliding a chip actuator with respect
to a lighter casing in such a manner that the actuating operation
fits naturally with the lighter casing for facilitating convenient
actuation of the lighter. In other words, the operation of the
present invention is not adversely affected by the specifically
shaped lighter casing.
[0013] Another object of the present invention is to provide a
lighter which comprises a lighter casing substantially and
realistically resembling a chip stack so as to avoid it from being
recognized as a lighter when it is not in use.
[0014] Another object of the present invention is to provide a
lighter which does not involve complicated mechanical structure so
as to minimize the manufacturing cost of the present invention.
[0015] Accordingly, in order to accomplish the above objects, the
present invention provides a lighter, comprising:
[0016] a lighter casing, which is shaped and sized to form a stack
of chips, comprising an outer chip wall and an opposed guiding
wall, wherein the lighter casing has a fuel-storage cavity formed
between the chip wall and the guiding wall for storing liquefied
gas and a guiding slot formed on the guiding wall;
[0017] a gas valve upwardly extended from the fuel-storage cavity
for releasing the gas therein when the gas valve is uplifted;
[0018] an ignition nozzle supported in the lighter casing to
communicate with the gas valve;
[0019] a piezoelectric unit disposed in the lighter casing for
generating piezoelectricity, wherein the piezoelectric unit has a
movable part and a spark generating tip which is extended towards
the ignition nozzle and is arranged when the piezoelectric unit is
compressed, a spark is generated at the spark generating tip for
igniting the emitted gas through the ignition nozzle; and
[0020] an actuation mechanism, which comprises:
[0021] a chip actuator, which is sized and shaped corresponding to
the chip wall, slidably mounted on the guiding wall of the lighter
casing between an idle position and an ignition position; and
[0022] an actuating arm extended from the chip actuator into the
lighter casing through the guiding slot at a position above the
movable part of the piezoelectric unit, wherein at the idle
position, the chip actuator is coaxially aligned with the guiding
wall that the chip actuator is overlapped with the stack of chips,
and at the ignition position, the chip actuator is slid on the
guiding wall to drive the actuating arm to depress the movable part
of the piezoelectric unit and to simultaneously lift up the gas
valve so as to ignite the lighter.
[0023] These and other objectives, features, and advantages of the
present invention will become apparent from the following detailed
description, the accompanying drawings, and the appended

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0030] Referring to FIG. 1 to FIG. 4 of the drawings, a lighter
according to a preferred embodiment of the present invention is
illustrated, in which the lighter comprises a lighter casing 10, a
gas valve 20, an ignition nozzle 30, a piezoelectric unit 40, and
an actuation mechanism 50.
[0031] The lighter casing 10 is shaped and sized to form a stack of
chips, and comprises an outer chip wall 11 and an opposed guiding
wall 12, wherein the lighter casing 10 has a fuel-storage cavity 13
formed between the chip wall 11 and the guiding wall 12 for storing
liquefied gas, and at least one guiding slot 14 formed on the
guiding wall 12.
[0032] The gas valve 20 is upwardly extended from the fuel-storage
cavity 13 for releasing the gas therein when the gas valve 20 is
uplifted.
[0033] The ignition nozzle 30 is supported in the lighter casing 10
to communicate with the gas valve 20.
[0034] The piezoelectric unit 40 is disposed in the lighter casing
10 for generating piezoelectricity, wherein the piezoelectric unit
40 has a movable part 41 and a spark generating tip 42 which is
extended towards the ignition nozzle 30 and is arranged when the
piezoelectric unit 40 is compressed at the movable part 41, a spark
is generated at the spark generating tip 42 for igniting the
emitted gas through the ignition nozzle 30.
[0035] The actuation mechanism 50 comprises a chip actuator 51 and
an actuating arm 52. The chip actuator 51, which is sized and
shaped corresponding to the chip wall 11, is slidably mounted on
the guiding wall 12 of the lighter casing 10 for sliding between an
idle position and an ignition position.
[0036] On the other hand, the actuating arm 52 is extended from the
chip actuator 51 into the lighter casing 10 via the guiding slot 14
at a position above the movable part 41 of the piezoelectric unit
40, wherein at the idle position, the chip actuator 51 is coaxially
aligned with the guiding wall 12 that the chip actuator 51 is
overlapped with the stack of chips, and at the ignition position,
the chip actuator 51 is slid on the guiding wall 12 to drive the
actuating arm 52 to depress the movable part 41 of the
piezoelectric unit 40 and to simultaneously lift up the gas valve
20 so as to ignite the lighter.
[0037] According to the preferred embodiment of the present
invention, the lighter casing 10, having a circular cross section,
further has a surrounding wall 15 integrally formed between the
outer chip wall 11 and the guiding wall 12 for enclosing the fuel
storage cavity 13 within the chip wall, the guiding wall 12 and the
surrounding wall 15. Moreover, the lighter casing 10 further has a
plurality of chip grooves 16 peripherally and indently formed along
the surrounding wall 15 of the lighter casing 10 for forming the
stack of chips thereof, and an ignition opening 17 formed on the
surrounding wall 15 of the lighter casing 10 for substantially
aligning with the ignition nozzle 30 so that the lighter is adapted
to be ignited at the ignition nozzle 30 to create controlled fire
delivered through the ignition opening 17. It is worth noting that
a distance between each two chip grooves 16 equals to a thickness
of the chip actuator 51.
[0038] Referring to FIG. 2 of the drawings, the lighter body 10
further has two sliding slots 19 formed on the guiding wall 12,
whereas the chip actuator 51 further comprises two sliding guiders
512 extended therefrom and are aligned with the two sliding slots
19 respectively so that when the chip actuator 51 is slid between
the idle position and the ignition position, the two sliding
guiders 512 are arrange to slide along the corresponding sliding
slots 19 respectively so as to substantially guide the sliding
movement of the chip actuator 51.
[0039] Referring to FIG. 5 and FIG. 6 of the drawings, the outer
chip wall 11 is embodied as having an aesthetic appearance
substantially resembling a real chip so that when the lighter is
laid on a flat surface, the aesthetic appearance of the lighter
body 10 resembles closely that of a chip stack.
[0040] The chip actuator 51 has an aesthetic appearance resembling
much of a chip and slidably mounted on the guiding wall 12 of the
lighter body 10 for moving between the idle position and the
ignition position. As shown in FIG. 4 and FIG. 5 of the drawings,
the lighter body has two connecting holes 18 formed on the outer
chip wall 11 wherein two connectors, such as two screws, are
arranged to insert into the two connecting holes 18 respectively
for connecting the lighter body with other elements stored within
the fuel-storage cavity 13.
[0041] According to the preferred embodiment of the present
invention, the guiding slot 14 is vertically formed on the guiding
wall 12 so that the actuating arm 52 is arranged to vertically
slide along the guiding wall 12 when the chip actuator 51 is moving
between the idle position and the ignition position.
[0042] It is worth mentioning that the guiding slot 14 may
alternatively have a curved cross section so that the chip actuator
51 is slid along the guiding slot 14 between the idle position and
the ignition position following the curved locus of the guiding
slot 14.
[0043] The lighter further comprises a refueling inlet 60 provided
on the surrounding wall 15 of the lighter casing 10 to communicate
with the fuel-storage cavity 13 thereof, wherein a user is able to
inject liquefied gaseous fuel to the fuel-storage cavity 13 via the
refueling inlet 60 for refueling the liquefied gaseous fuel so as
to allow the lighter to be supplied with sufficient amount of fuel
for generating ignition.
[0044] As a result, it is important to point out that the chip
actuator 51 has an actuating surface 511 formed as an outer wall
thereof for allowing a user to grip on the actuating surface 511 so
as to slide the chip actuator 51 moving from the idle position to
the ignition position. Since the chip actuator 51 is shaped and
sized to have a chip's aesthetic appearance having a circular cross
section, the user is able to conveniently and effectively grip the
circular actuating surface 511 for sliding the chip actuator 51
moving from the idle position to the ignition position. The
actuating surface 511 of the chip actuator 51 has a predetermined
roughness formed as an outer side thereof for allowing a user to
frictionally engage with the actuating surface 511 so as to slide
the chip actuator 51 moving from the idle position to the ignition
position.
[0045] Referring to FIG. 3 to FIG. 4 of the drawings, the actuating
arm 52 comprises a pivot pusher 521 pivotally supported in the
lighter casing 10 at a position on top of the movable part 41 of
the piezoelectric unit 40 to control the gas valve 20, and a
sliding arm 522 which is extended from the clip actuator 51 to
slidably engage with the guiding slot 14 and is coupled with the
pivot pusher 521 such that when the sliding arm 522 is driven to
downwardly slide at the guiding slot 14 by the clip actuator 51,
the sliding arm 522 pivotally drives the pivot pusher 521 to
depress the movable part 41 of the piezoelectric unit 40 and to
simultaneously lift up the gas valve 20 for ignition of the
lighter.
[0046] The sliding arm 522, having a T-shape cross section, has an
elongated arm portion 5221 sliding along the guiding slot 14 and an
enlarged head portion 5222 extended from the arm portion 5221 to
couple with the pivot pusher 521 so as to ensure the sliding arm
522 sliding along the guiding slot 14.
[0047] In order to retain the chip actuator 51 sliding on the
lighter body 10, the guiding slot 14 has an upper elongated slot
portion 141 having a width slightly larger than a width of the arm
portion 5221 of the sliding arm 522, and a bottom enlarged slot
portion 142 having a width slightly larger a width of the head
portion 5222 of the sliding arm 522, so as to allow the sliding arm
522 slidably engaging with the guiding slot 14, wherein a length of
the upper elongated slot portion 141 of the guiding slot 14 is
longer than a depression distance of the movable part 41 of the
piezoelectric unit 40, so that when the sliding arm 522 is driven
to depress, the movable part 41 of the piezoelectric unit 40 can be
completely depressed to produce the spark at the spark generating
tip 42.
[0048] According to the preferred embodiment of the present
invention, the pivot pusher 521 has a first end pivotally mounted
in the fuel-storage cavity 13, a second end extended to align with
the actuating arm 52, and a depressing member extended from between
the first end and the second end to align with the movable part 41
of the piezoelectric unit 40, in such a manner that when the chip
actuator 51 is depressed from the idle position to the ignition
position, the actuating arm 52 is driven to depress the first end
so as to pivotally drive the depressing member to move downwardly
for depressing the movable part 41 of the piezoelectric unit
40.
[0049] Moreover, the lighter further comprises a lever connecting
between the movable part 41 of the piezoelectric unit 40 and the
gas valve 20 so that when the movable part 41 is depressed, the gas
valve is arranged to be uplifted by the lever.
[0050] The operation of the present invention is as follows: the
chip actuator 51 is normally retained at the idle position so that
the lighter substantially resembles a chip stack. When the user
wishes to ignite the lighter, the user needs to slide downwardly
the chip actuation 51 so that the actuating arm 52 is driven to
slide downwardly along the guiding slot 14. When the actuating arm
52 is driven to slide downwardly along the guiding slot 14, it is
driven to depress the movable part 41 of the piezoelectric unit 40
for generating spark at the spark generating tip 42 and at the same
time lifting up the gas valve 20 for release gaseous fuel at the
ignition nozzle 30. The released gaseous fuel is then ignited by
the spark produced at the spark generating tip 42 so as to ignite
the lighter of the present invention. When the user finishes using
the lighter, the actuating arm 52 is automatically rebounded by the
movable part 41 of the piezoelectric unit 40 via the pivotal pusher
521 so as to slide upwardly along the guiding slot 14 for drive the
chip actuator 51 to return to the idle position. When the chip
actuator 51 is at the idle position, the lighter casing 10 and the
chip actuator 51 form the chip stack.
[0051] From the forgoing descriptions, it can be shown that the
above mentioned objects have been substantially accomplished. The
present invention provides a lighter comprising the outer casing 10
and the actuation mechanism 50 for forming the chip stack aesthetic
appearance for enhancing an actuation of the lighter and at the
same time avoiding it from being recognized as a lighter.
[0052] One skilled in the art will understand that the embodiment
of the present invention as shown in the drawings and described
above is exemplary only and not intended to be limiting.
[0053] It will thus be seen that the objects of the present
invention have been fully and effectively accomplished. It
embodiments have been shown and described for the purposes of
illustrating the functional and structural principles of the
present invention and is subject to change without departure from
such principles. Therefore, this invention includes all
modifications encompassed within the spirit and scope of the
following claims.
