DETAILED DESCRIPTION
[0026] The invention will be understood from the following detailed
description of embodiments of the invention, which are meant to be
descriptive and not limiting. For the sake of brevity, some
well-known features are not described in detail.
[0027] The reference numbers have been used to point out elements
in the embodiments described and illustrated herein, in order to
facilitate the understanding of the invention. They are meant to be
merely illustrative, and not limiting. Also, the foregoing
embodiments of the invention have been described and illustrated in
conjunction with systems and methods thereof, which are meant to be
merely illustrative, and not limiting.
[0028] FIG. 1 is a perspective front view of a prior art gas stove,
lacking one knob.
[0029] The term "gas stove" refers herein to a gas dispenser for
cooking.
[0030] A prior art gas stove 62 includes several removable
knobs.
[0031] FIG. 2 is a magnification of FIG. 1, and presenting the
time-set accessory according to one embodiment of the
invention.
[0032] A knob 68C is being removed, thus exposing the rotational
operating lever 40, and a time-set accessory 10 is being placed on
lever 40 instead of knob 68C.
[0033] FIG. 3 is a side sectional view of the time-set accessory of
FIG. 2, being attached to the lever of FIG. 2, at the locked
state.
[0034] Time-set accessory 10 is being attached to lever 40. Gas
time 10 includes a knob 42, being rotatable in relation to the body
70, for rotating lever 40 in relation to gas stove 62 of FIG.
2.
[0035] A magnet or another anchor 20 anchors body 70 to the front
board 72 (enumerated in FIG. 2) of gas stove 62, such that rotation
of knob 42 in relation to body 70 rotates lever 40, together with a
plate 16 fixed thereto, in relation to front board 72.
[0036] However, a linear spring 32 normally presses a bolt 34 or
another obstacle to the left as shown by an arrow 36.
[0037] FIG. 4 is a perspective view of the bolt and the plate of
FIG. 3 at the locked state of FIG. 3.
[0038] Linear spring 32 normally presses bolt 34 to the left into a
depression 24A of plate 16, thus does not allow rotation of plate
16, and of lever 40, as shown by a disallowed arrow 90.
[0039] Knob 42 includes a depression 64 being shaped complementary
to lever 40.
[0040] FIG. 5 is the side sectional view of FIG. 3 at the
non-locked state.
[0041] An electromagnet 18 may retract bolt 34 to the right, as
shown by arrow 38, against the mechanical force of linear spring
32.
[0042] Electromagnet 18 may be triggered either manually by a
user-operable switch 44, or automatically by an electric timer
26A.
[0043] FIG. 6 is an electric circuit for triggering the
electromagnet of FIG. 5.
[0044] Electromagnet 18 may be triggered either manually by
user-operable switch 44, or automatically by a switch 82 of
electric timer 26A, since user-operable switch 44 and switch 82 are
disposed in parallel. However, both of switches 44 and 82 are
normally open, as shown by springs 84A and 84B.
[0045] Thus, referring to FIG. 3, electromagnet 18 normally is not
triggered, thus normally linear spring 32 normally presses bolt 34
to the left into depression 24A, thus does not allow rotation of
plate 16, and of lever 40.
[0046] FIG. 7 is a perspective view of the bolt and the plate of
FIG. 3 at the non-locked state of FIG. 5.
[0047] Triggering of electromagnet 18 removes bolt 34 from
depression 24A.
[0048] Prior art gas stove 62 is characterized in that the
rotational state of lever 40 is which adjusts the intensity of the
cooking.
[0049] Since the rotation of plate 16 by knob 42 rotates lever 40,
and since bolt 34 is not rotational, the intensity of the cooking
is a function of which depression of plate 16 is currently disposed
against bolt 34.
[0050] FIG. 8 is a front sectional view of the time-set accessory
of FIG. 2 at the closed state.
[0051] At the first step, and referring to FIG. 8, being the normal
initialization state, a circular spring (mainspring) 14, shown also
in FIG. 5, tends to rotate plate 16 together with knob 42 and lever
40 along direction 58 towards the gas non-dispensing state, until a
barrier 92, being stationary in relation to body 70 of FIG. 3, does
not allow further rotation of knob 42 in relation to body 70.
[0052] At this state, and referring again to FIG. 3, linear spring
32 presses bolt 34, thus bolt 34 does not allow the user to rotate
plate 16 together with knob 42 and lever 40, since bolt 34 might
enter any of depressions 24A, 24B, etc., lever 40 locks the gas
dispensing to the non-dispensing state.
[0053] At the second step, and referring again to FIG. 6, the user
manually closes user-operable switch 44.
[0054] At the third step, being induced by the second step, and
referring again to FIG. 5, bolt 34 is retracted (to the right in
the figure) by electromagnet 18 against linear spring 32.
[0055] The retraction of bolt 34 allows the user, as shown in FIG.
7, to rotate plate 16 together with knob 42 and lever 40, since
bolt 34 does not enter any of depressions 24A, 24B, etc.
[0056] At the fourth step, and referring again to FIG. 8, the user
may rotate plate 16 together with knob 42 and lever 40 in direction
80, against circular spring 14, to a desired gas intensity
state.
[0057] FIG. 9 is the front sectional view of FIG. 8 after the
fourth step.
[0058] Since the user has rotated plate 16 and knob 42 against
circular spring 14, circular spring 14 is more tense in FIG. 9.
According to the example of FIG. 9, the user has selected the gas
intensity state in which bolt 34 is disposed against depression
24D.
[0059] At the fifth step, and referring again to FIG. 6, the user
opens user-operable switch 44 to cancel the electromagnetic
force.
[0060] At the sixth step, being induced by the fifth step, and
referring again to FIG. 3, linear spring 32 presses bolt 34, to
enter depression 24D, thereby locking the rotational state of plate
16 together with knob 42 and lever 40, thereby locking the gas
dispensing to the selected gas intensity.
[0061] FIG. 10 depicts the setting of the electric timer of FIG.
6.
[0062] At the seventh step, the user may select a time 86, for
which switch 82 of FIG. 6 remains open.
[0063] At the eighth step, and referring again to FIG. 6, electric
timer 26A automatically closes switch 82, thus triggers
electromagnet 18.
[0064] At the ninth step, being induced by the eighth step, and
referring again to FIG. 5, bolt 34 is retracted (to the right in
the figure) by electromagnet 18 against linear spring 32.
[0065] At the tenth step, being induced by the ninth step, and
referring yet to FIG. 5, circular spring 14 rotates plate 16
together with knob 42 and lever 40 from the selected gas intensity
state of FIG. 9, back to the non-dispensing state of FIG. 8.
[0066] FIG. 11 is a side sectional view of the time-set accessory
of FIG. 2, according to another embodiment, being attached to the
lever of FIG. 2, at the locked state.
[0067] According to this embodiment, electric timer 26A of FIG. 3,
may be replaced by a mechanical timer 26B, as described
following.
[0068] Time-set accessory 10 is being attached to lever 40, and
includes knob 42, being rotatable in relation to body 70, for
rotating lever 40 in relation to gas stove 62 of FIG. 2.
[0069] A linear spring 32 normally presses bolt 34, through a
toggle 60 to the left as shown by an arrow 36.
[0070] FIG. 12 is the side sectional view of FIG. 3 at the
non-locked state.
[0071] Instead of electromagnet 18 of FIG. 5, a linear spring 30,
being stronger than linear spring 32, may retract bolt 34, through
toggle 60, to the right, as shown by arrow 38, against the
mechanical force of linear spring 32.
[0072] Linear spring 30 may be active by disposing a rod 98 against
a hole 74, either manually, or automatically by mechanical timer
26B. Once linear spring 30 is inactive, linear spring 32 presses
bolt 34 to the left into depression 24A, thus does not allow
rotation of plate 16, and of lever 40.
[0073] At the first step, and referring to FIG. 8, being the normal
initialization state, circular spring 14 tends to rotate plate 16
together with knob 42 and lever 40 along direction 58 towards the
gas non-dispensing state, until barrier 92, being stationary in
relation to body 70 of FIG. 11, does not allow further rotation of
knob 42 in relation to body 70.
[0074] At this state, and referring again to FIG. 11, linear spring
32 presses bolt 34, thus bolt 34 does not allow the user to rotate
plate 16 together with knob 42 and lever 40, since bolt 34 might
enter any of depressions 24A, 24B, etc., lever 40 locks the gas
dispensing to the non-dispensing state.
[0075] At the second step, and referring to FIG. 12, the user
inserts rod 98 into hole 74.
[0076] At the third step, being induced by the second step, and
referring yet to FIG. 12, bolt 34 is retracted (to the right in the
figure) by spring 30 against linear spring 32.
[0077] The retraction of bolt 34 allows the user, as shown in FIG.
7, to rotate plate 16 together with knob 42 and lever 40, since
bolt 34 does not enter any of depressions 24A, 24B, etc.
[0078] At the fourth step, and referring again to FIG. 8, the user
may rotate plate 16 together with knob 42 and lever 40 in direction
80, against circular spring 14, to a desired gas intensity
state.
[0079] According to the example of FIG. 9, the user has selected
the gas intensity state in which bolt 34 is disposed against
depression 24D.
[0080] At the fifth step, and referring again to FIG. 11, the user
pulls rod 98 out of hole 74 to cancel the force of spring 30 on
toggle 60.
[0081] At the sixth step, being induced by the fifth step, and
referring yet to FIG. 11, linear spring 32 presses bolt 34, to
enter depression 24D, thereby locking the rotational state of plate
16 together with knob 42 and lever 40, thereby locking the gas
dispensing to the selected gas intensity of FIG. 9.
[0082] FIG. 13 depicts the setting of the mechanical timer of FIG.
11.
[0083] At the seventh step, the user may rotate rod 98 about an
axle 46, for not allowing rod 34 to enter hole 74.
[0084] FIG. 14 is a front view of the time-set accessory at the
state of FIG. 13.
[0085] The rotation of rod 34 about axle 46 further selects a time
86, for which spring 30 cannot press toggle 60 of FIG. 13.
[0086] At the eighth step, mechanical timer 26B rotates rod 34
about axle 46 towards hole 74.
[0087] FIG. 15 is the front view of the time-set accessory at the
end of the eighth step, and at the next steps.
[0088] At the end of the eighth step, being after the set time, rod
34 enters hole 74.
[0089] At the ninth step, being induced by the eighth step, and
referring again to FIG. 12, bolt 34 is retracted (to the right in
the figure), through toggle 60 by spring 30 against linear spring
32.
[0090] At the tenth step, being induced by the ninth step, and
referring yet to FIG. 12, circular spring 14 rotates plate 16
together with knob 42 and lever 40 from the selected gas intensity
state of FIG. 9, shown also in FIG. 14, back to the non-dispensing
state of FIG. 8, shown also in FIG. 15.
[0091] Thus, in one aspect, the invention is directed to a time-set
accessory (10), including: [0092] a knob (42), being shaped
complementary (64) to a lever (40) of a gas stove (62), for
allowing manual rotation of the lever (40), for selecting a
dispensing extent of the gas stove (62); [0093] an anchor (20), for
anchoring the body (70) of the time-set accessory (10) to the body
(72) of the gas stove (62), thereby rotation of the knob (42) about
the time-set accessory's body (70), rotates the lever (40) about
the gas stove's body (72); and [0094] a timer (26A, 26B), for
manually setting a time (86), and for further automatically
rotating the knob (42) about the time-set accessory's body (70)
upon termination of the time (86), thereby rotating the lever (40)
about the gas stove's body (72).
[0095] The time-set accessory (10) may further include: [0096] a
circular spring (14), for applying the automatic rotation of the
knob (42) about the time-set accessory's body (70); and [0097] an
obstacle (34), for allowing and disallowing (90) the circular
spring (14), wherein the allowing and disallowing is activated
manually and by the timer (26A, 26B).
[0098] The time-set accessory (10) may further include: [0099] a
plurality of depressions (24A, 24B), each corresponding to a
different rotational state of the knob (42); and [0100] a bolt
(34), for allowing locking the knob (42) to any of the depressions
(24A, 24B), thereby the automated rotation of the lever (40)
constitutes automated rotation from the rotational state of the
knob (42), being from a gas intensity selected by the user, to
turning the gas to off.
[0101] The manual and automatic rotation of the knob (42) applies,
prior thereto, releasing of the locking.
