The subject matter disclosed herein relates in general to candles, and more specifically to a device and method for automatically extinguishing the burning flame of a candle after a user-defined preset amount of time has passed.
Candles are ubiquitous, having been used for thousands of years as a source of light. Recently, candles have taken on more of a sleek and simplistic design, allowing them to be used to enhance esthetics in home decor. Also, scented or fragrant candles are being used for aromatherapy for relaxation and stress reduction, among other uses. However, a lighted candle is also an open flame and, thus, a potential fire hazard. Thousands of home structure fires occur each year in the U.S. with many more occurring around the world. Many of these fires are caused by the burning flame of a candle not being put out or extinguished properly and/or in a timely manner. It's easy for someone to fall asleep or forget about a burning candle in a room, thereby leaving the open burning flame unattended with the high potential for causing a harmful fire if the flame is not extinguished in a timely manner. Thus, candles today remain both immensely popular and also potentially hazardous.
Known, prior art candle extinguishing devices (aka “snuffers” or “douters”) date back to the 1700's. These were relatively simple manually operated devices. More modern automatic devices are known which, in general, are operated mechanically to extinguish the burning flame of a candle (i.e., the burning wick of the candle). However, heretofore, no known device exists for automatically and reliably extinguishing the burning flame of a candle after a preset amount of time set by the user has passed and without the need for a human to check that the burning flame of the candle has indeed been extinguished, and all the while the device is safe, stylish, and easy-to-use. Thus, there is a need for a timed automatic candle extinguishing device that easily attaches to many popular sizes of candles.
An object of embodiments of the present invention is to automatically and reliably extinguish the burning flame of a candle after a preset amount of time has passed.
Another object of embodiments of the present invention is to provide a device that automatically extinguishes the burning flame of a candle using a leaf shutter aperture to shut off or stop the supply or flow of oxygen to the candle flame after a preset amount of time has passed, thereby starving the flame.
Yet another object of embodiments of the present invention is to provide a device that automatically and reliably extinguishes the burning flame of a candle without the need for human intervention to be certain that the candle flame has indeed been extinguished, thereby removing the burden of extinguishing the burning candle flame from a human.
Still another object of embodiments of the present invention is to eliminate a potential fire hazard by automatically and reliably extinguishing the burning flame of a candle after a preset amount of time has passed.
Another object of embodiments of the present invention is to provide a device that is configured to readily and easily fit onto or attach to a standard size jar or container candle and is operable to automatically and reliably extinguish the burning flame of the jar candle.
Yet another object of embodiments of the present invention is to replace the standard lid on a jar candle with a device that automatically extinguishes the burning flame of the jar candle.
Still another object of embodiments of the present invention is to provide a device that automatically and reliably extinguishes the burning flame of a candle while at the same time having a relatively sleek, low-profile design that complements the design of the candle to which it is attached.
Another object of embodiments of the present invention is to provide a candle extinguishing device that can be configured in a number of different overall sizes to be engaged and operable with corresponding candles of many different sizes.
Yet another object of embodiments of the present invention is to provide a device that automatically and reliably extinguishes the burning flame of a candle while at the same time itself being fireproof and unaffected by the heat given off by the burning flame of the candle.
Still another object of embodiments of the present invention is to provide a device that automatically and reliably extinguishes the burning flame of a candle regardless of the remaining level or amount of material (e.g., wax) in the jar candle.
According to an embodiment of the present invention, a candle flame extinguishing device is configured to attach to an opening in a container for a candle. The device includes an aperture that is movable between open and closed (i.e., partially or fully closed) positions. The open position of the aperture facilitates the lighting of the candle wick and the burning of the candle flame. The closed position of the aperture deprives the burning candle flame of oxygen thereby extinguishing the burning candle flame. A timer controls the opening and closing of the aperture. The timer is set by a user to a desired amount of time that the candle flame is to burn for. After the preset amount of burn time has passed, the aperture automatically closes a sufficient amount (either partially or fully) to extinguish the burning flame of the candle.
The subject matter, which is regarded as the disclosure herein of exemplary embodiments of the present invention, is particularly pointed out and distinctly claimed in the claims at the conclusion of this specification. The forgoing and other features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
It should be understood that, throughout this patent application and specifically in the written description that follows and in the accompanying drawing figures, various directional terms such as horizontal, vertical, up, down, upwardly, downwardly, front, back, top, bottom, upper, lower, left, right, and other similar terms as they are used herein refer to the candle extinguishing device of the various exemplary embodiments of the present invention as that device is oriented when it is typically attached to a candle (e.g. a glass jar candle). All of these terms are used in this written description and in the drawings for convenience only and as an aid to better understanding the exemplary embodiments of the present invention. These terms are not intended to be limiting or to imply that the candle extinguishing device must be used or positioned in any particular direction or orientation.
Referring to
The glass container 24 of the typical jar candle 20 has an upper flange portion 36 that is circular and defines a corresponding circular opening 40 in the top of the container 24. A user lights the candle 20 by lighting the wick 32. As the candle wick 32 burns, the amount of candle material 28 within the glass container 24 is slowly reduced over time through melting and vaporization.
A separate cover or lid 44 is provided that is configured to be inserted within the opening 40 and is operable to close off the opening 40. The upper flange portion 36 of the glass container 24 is illustrated as being a smooth surface (i.e., without any threads or other protrusions). As such, the lid 44 fits directly and snugly within the opening 40. Although not clearly shown in

After the candle flame extinguishing device 48 is secured to the top of the jar candle 20, the device is operable, in general, by a user manually twisting or rotating a dial 52 of the device 48 in one direction (e.g., clockwise) when the user wants to light the wick 32 of the candle 20 at a desired time. This manual rotation causes an aperture 56 in the center of the device 48 to open, thereby exposing the candle material 28 and wick 32 below the device 48. This allows a user to light the wick 32 of the candle 20. The same manual rotation of the dial 52 also causes a mechanical timer 60 (
The device 48 extinguishes the burning flame by partially or fully closing the aperture 56, thereby depriving the burning flame of oxygen. In some embodiments, the aperture 56 may not need to be closed fully to sufficiently deprive the burning flame of oxygen. Instead, the broadest scope of the present invention contemplates that the aperture be closed an amount that sufficiently deprives the burning flame of oxygen, thereby reliably and repeatedly extinguishing the burning flame of the candle 20. Thus, as used herein in describing the aperture 56, the term “closed’ refers to a full or a partial closure of the aperture 56. Further, the device 48 automatically and reliably extinguishes the burning flame of the jar candle 20 regardless of the remaining level or amount of candle material 28 in the jar candle 20. The aperture 56 is closed by the dial 52 being rotated automatically by the timer 60 in a direction (e.g., counterclockwise) that is opposite to that direction (e.g., clockwise) which set the timer with a preset amount of time. A more detailed description of the operation of the candle flame extinguishing device 48 is provided hereinafter.
Referring to
A top housing 76 is provided which fits over the timer 60 and outer housing 72. Next, the aperture 56 is integrated together with a dial gear 80, the dial 52, and a dial holder 84. These components 52, 56, 80, 84 may attach to the top housing 76 using, e.g., flat head screws. The dial holder 84 attaches or connects together the dial 52, the dial gear 80, and the aperture 56. As mentioned hereinbefore, the dial 52 is manually rotated by the user to an aperture open position and connects with and turns the dial gear 80. The dial 52 may have a textured outer surface around its perimeter to provide for better gripping by the user. The aperture 56 may comprise a leaf shutter aperture 56, similar to those used in cameras. The leaf shutter aperture 56 may comprise a plurality of leaves (e.g., sixteen) connected with a single arm in a known manner. In the embodiment of
Referring to
To open the aperture 56 and set the timer 60 to a desired amount of time before the aperture 56 is automatically closed and the candle 20 is extinguished, the user manually rotates the dial 52 clockwise. More specifically, the dial 52 is rotated from an aperture closed starting position (as indicated by “Close” in
As the timer 60 is counting down the preset amount of time, the dial 52 rotates counterclockwise slowly towards the “Open” position in
Referring to
As seen in
In addition, when the user starts to rotate the dial 52 clockwise from the approximate 9 o'clock position, the aperture 56 begins to open. Then when the dial 52 is rotated to approximately the second to last dot position near the 7 o'clock position, the aperture 56 is locked in the open position. Also at this position, the timer 60 starts being wound.
Beginning at the approximate 7 o'clock position and moving counterclockwise to the approximate 3 o'clock position, a series of numbers 124 are shown. In the exemplary embodiment of
It should be understood that use of the window 108 to display the indicia is purely exemplary. Other means for displaying the indicia are contemplated by the broadest scope of the present invention. For example, the indicia may be displayed on the outer perimeter of the top housing—e.g., on the textured outer surface of the dial 52. Also, indicia other than dots or numbers may be used. Further, indicia other than or in conjunction with visual indicia may be provided to the user (e.g., audible).
The various components comprising the candle flame extinguishing device 48 of exemplary embodiments of the present invention may be made from a rigid material such as a metal (e.g., aluminum or steel) or a high temperature plastic. The metal provides the device 48 with a weighted, high-quality feel. For device components that are relatively close to the burning candle flame, aluminum may be used for structure parts, and zinc casting with chrome plating may be used for cosmetic parts. The high temperature plastic may be used for device components that are relatively far away from the burning candle flame. The high temperature plastic may comprise, for example and without limitation, polybutylene terephthalate with glass fiber, or polyphenylene sulfide. However, it is to be understood that the various components comprising the device 48 may be made from any suitable and durable high temperature materials, including those that are light weight. In general, all of the components comprising the candle flame extinguishing device 48 of embodiments of the present invention must meet the consumer and fire safety regulations, laws, and standards of the United States and of its various states, along with similar fire safety regulations of each of the various countries that the device 48 will be marketed, sold, and utilized in.
The candle flame extinguishing device 48 of exemplary embodiments of the present invention has been described and illustrated as having a mechanical timer 60 that is disposed in a support structure 88 which juts out from the device 48 (
In addition, it should be understood that the use of a mechanical timer 60 as described and illustrated herein is exemplary and is not a part of the broadest scope of the invention. The timer 60 may be other than a mechanical timer—for example, the timer 60 may comprise a digital or analog electronic timer. As such, the digital timer may allow for integration with a circuit board to allow for control of the device 48 via a digital screen interface or via a mobile app on a phone.
Also, the use of a spring 104 to open and close the aperture 56 is exemplary. Instead, a motor could be used to open and close the aperture 56.
Further, the broadest scope of the present invention contemplates other ways that the candle flame extinguishing device 48 may attach to the jar candle 20. For example, threads similar to those of a standard canning jar and lid may be utilized. Also, the device 48 may be permanently attached to the jar candle 20 as a single container and device from a mold. In addition, the device 48 may magnetically attach to the candle 20 using a magnetic metal rim around the container 24 to attract magnets embedded in the bottom/inner housing of the device 48. Also, a rubber strap and latch system may be used to secure the device 48 to the container 24. Further, a rubber/metal clamp similar to a hose clamp may be used to tighten the device 48 around the container 24.
In addition, instead of use of a twisting motion of the dial 52 to set the desired amount of time for the timer 60, a different motion may be used, e.g., utilizing an actuator engaging with the timer staging gear 96, or allowing for the pressing down on the device 48 to wind the timing staging gear 96, or use of a small lever attached to a 90 degree right angle transmission that winds the timer staging gear 96 as the lever is pulled down.
Also, although not shown or described hereinbefore, the device 48 may include an “override” mechanism or electronic means that allows the user to close the aperture 56 at any time prior to the passage of the preset amount of time in the timer 60. For example, the user can press or switch a button or lever which disengages the clutch 100 or releases the pawl in the ratchet/pawl mechanism. If a digital electronic embodiment is utilized as part of the device 48, then a user command through an app or through use of an electronic switch can be used to close the aperture 56 at any time.
The exemplary embodiments of the candle flame extinguishing device 48 described and illustrated herein have been described as having a leaf shutter aperture 56. However, the broadest scope of the present invention is not limited as such. Instead, the aperture 56 may comprise a fire-resistant cloth, a thin, flexible high-temperature plastic sheet, or other similar materials. The cloth or sheet acts as a curtain and is pulled open or shut by the arm that is attached to the aperture 56. Similar to the leaf shutter aperture 56, when the dial is twisted, the cloth or sheet curtain will open allowing oxygen to flow to the candle flame thereby allowing the candle flame to burn. When the desired amount of time has passed, the arm will disengage and the spring will drive the arm back to the stop, closing the curtain and starving the flame of oxygen, thereby extinguishing the flame of the candle 20.
It should be understood by one of ordinary skill in the art that the exemplary embodiments of the candle flame extinguishing device 48 described and illustrated herein are not limited for use with a standard size 22-ounce jar candle 20. Instead, it should be readily apparent in light of the teachings here that the candle flame extinguishing device 48 and its various components of the device 48 can be appropriately sized to fit different sized candles 20. Further, a locking mechanism may be incorporated into the device 48 or used alongside the device 48 to prevent the unwanted or unauthorized opening of the aperture 56. For example, a padlock or other type of mechanical lock may be utilized to prevent the twisting of the device 48 and thereby prevent the opening of the aperture 56 and winding of the timer 60 until the lock is unlocked, e.g., with a key. A digital lock may be incorporated requiring a passcode or fingerprint/retina scan to allow the aperture 56 to be opened and the timer 60 set.
As described and illustrated herein, the device 48 of the various exemplary embodiments of the present invention is used primarily for extinguishing the burning flame of a candle 20 by selectively shutting off the supply of oxygen to the candle flame. However, it is to be noted that the device 48 of embodiments of the present invention is not limited as such. Instead, the device 48 of the present invention may be used in other applications in which, in general, it is desired to control the provision of air, oxygen, or other gases, or of radiation such as visible or invisible light, or of other physical quantities such as water or liquids, to a medium or an end point using an aperture 56 that can be controlled between open and closed positions. For example, the device 48 may be attached to an end of a pipe or duct and a time is set to control air flow therethrough by controlling the opening or closing of the aperture 56. Similarly, the device 48 may be attached to a container (e.g., a jar) containing plants or other organisms to control an amount of sunlight or oxygen exposure to the plants by again controlling the opening or closing of the aperture 56. In addition to controlling radiation such as light for ajar containing organic material, the device 48 may also be enlarged in size to control light coming through a window, thereby controlling the amount of light entering a room in a house for example.
The device 48 may also be used to control the visual perspective of and/or to provide protection to a medium. For example, the device 48 may be placed in front of or attached to or incorporated into a painting, thereby allowing a timed control of the visual perspective to a viewer of the painting (or to control how long the painting can be viewed). The device 48 may also be used to provide protection of a painting from light, dust, vandalism, etc. after a set amount of time. Other medium examples include a television, projector, laptop/other screened devices, picture frame, and watch/clock. Further, the device 48 may be used to control access to a given item or space. For example, the device 48 may be attached to a cookie jar, allowing timed control of access to the cookies in the jar. The device 48 may also be enlarged in size to act as a door, granting access to a given area for a set amount of time,
Other contemplated embodiments of the broadest scope of the present invention include enlarging the size of the device 48 and using appropriate high-temperature resistant materials. This would allow the device 48 to be able to attach, to cover. or be molded or forged to a fire pit to control the time of burning of the material within the fire pit by allowing for a timed extinguishment of the fire pit flame by starving the fire of oxygen.
The terminology used herein is for the purpose of describing particular embodiments of the invention only and is not intended to be limiting of the invention. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, element components, and/or groups thereof.
While the invention is provided in detail in connection with only a limited number of embodiments, it should be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions, or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. Additionally, while various embodiments of the invention have been described, it is to be understood that the exemplary embodiments may include only some of the described exemplary aspects. Accordingly, the invention it not to be seen as limited by the foregoing description but is only limited by the scope of the appended claims.
