TIME-SET ACCESSORY
A time-set accessory, including: a knob, being shaped complementary to a lever of a gas stove, for allowing manual rotation of the lever, for selecting a dispensing extent of the gas stove; an anchor, for anchoring the body of the time-set accessory to the body of the gas stove, thereby rotation of the knob about the time-set accessory's body, rotates the lever about the gas stove's body; and a timer, for manually setting a time, and for further automatically rotating the knob about the time-set accessory's body upon termination of the time, thereby rotating the lever about the gas stove's body.
The invention relates to the field of timers. More particularly, the invention relates to a timer for controlling gas dispensing.
BACKGROUNDConventional timers for cooking gas dispensers open and close a gas pipe.
However, this approach is not safe, since it interferes the gas pipes.
There is a long felt need to provide a solution to the above-mentioned and other problems of the prior art.
SUMMARYIn one aspect, the invention is directed to a time-set accessory, including:
-
- a knob;
- an anchor;
- and a timer.
Embodiments, features, and aspects of the invention are described herein in conjunction with the following drawings:
The drawings are not necessarily drawn to scale.
DETAILED DESCRIPTIONThe 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.
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.
The term “gas stove” refers herein to a gas dispenser for cooking.
A prior art gas stove 62 includes several removable knobs.
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.
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
A magnet or another anchor 20 anchors body 70 to the front board 72 (enumerated in
However, a linear spring 32 normally presses a bolt 34 or another obstacle to the left as shown by an arrow 36.
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.
Knob 42 includes a depression 64 being shaped complementary to lever 40.
An electromagnet 18 may retract bolt 34 to the right, as shown by arrow 38, against the mechanical force of linear spring 32.
Electromagnet 18 may be triggered either manually by a user-operable switch 44, or automatically by an electric timer 26A.
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.
Thus, referring to
Triggering of electromagnet 18 removes bolt 34 from depression 24A.
Prior art gas stove 62 is characterized in that the rotational state of lever 40 is which adjusts the intensity of the cooking.
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.

According to this embodiment, electric timer 26A of
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
A linear spring 32 normally presses bolt 34, through a toggle 60 to the left as shown by an arrow 36.
Instead of electromagnet 18 of
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.

At the seventh step, the user may rotate rod 98 about an axle 46, for not allowing rod 34 to enter hole 74.
The rotation of rod 34 about axle 46 further selects a time 86, for which spring 30 cannot press toggle 60 of
At the eighth step, mechanical timer 26B rotates rod 34 about axle 46 towards hole 74.
At the end of the eighth step, being after the set time, rod 34 enters hole 74.

At the tenth step, being induced by the ninth step, and referring yet to
Thus, in one aspect, the invention is directed to a time-set accessory (10), including:
-
- 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);
- 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
- 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).
The time-set accessory (10) may further include:
-
- a circular spring (14), for applying the automatic rotation of the knob (42) about the time-set accessory's body (70); and
- 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).
The time-set accessory (10) may further include:
-
- a plurality of depressions (24A, 24B), each corresponding to a different rotational state of the knob (42); and
- 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.
The manual and automatic rotation of the knob (42) applies, prior thereto, releasing of the locking.
