Abstract
A timer is provided which is actuated by an incense stick burning to a given point at which point a pivotally movable hammer is released. When the hammer is released, it moves from its first retracted position to a second position in response to gravitational forces wherein it strikes a bowl to make a pleasant alarm sound. The timer is particularly useful and appropriate when used in conjunction with meditation or a similar exercise.
Description




BACKGROUND AND BRIEF SUMMARY




The present invention relates generally to a timer mechanism. More particularly, the present invention provides a timer mechanism actuated by a burning incense stick. When the incense stick has burned past a given point, a pivotally mounted hammer is released and allowed to strike a bowl to make a pleasant sound. The timer is particularly useful and appropriate when used in conjunction with meditation, but it may be used for other purposes as well.




The prior art includes incense burning apparatus as shown in U.S. Pat. No. 4,324,763 wherein a series of timer discs on a common shaft is rotated by an electric motor and the rim of each disc is provided with a bore for holding an incense stick. This patent does not teach the use of an individual incense stick to actuate an alarm when the stick has burned to a given point.




The prior art also includes incense stick holders such as shown in U.S. Pat. No. 5,873,370. However, that patent does not teach the triggering of an alarm as the incense stick burns to a given point.




The prior art also includes an ancient “dragon boat” alarm. The “dragon boat” has a silk thread carrying bronze bells at each end and the center of the silk thread is draped over the elevated dragon boat. An incense stick is placed next to the silk thread. When the burning incense stick reaches and burns through the silk thread, the bronze bells fall into a metal pan beneath the dragon boat. The dragon boat is more complicated than the present invention in that the user must reassemble the bronze bells with a new silk thread and drape the new thread over the dragon boat in order to reset the device. Also, the dragon boat design uses the burning property of the incense to burn through another element of the timer (namely, the silk thread) causing a release. In the present design, the incense acts as a physical support for the hammer and its burning removes this support, allowing the hammer to release and strike the bowl.




The present invention provides an easily resettable alarm actuated by a burning incense stick. The present invention also provides a pivotally mounted hammer which is held in its retracted position by an incense stick and, when the incense stick burns past a given point, the hammer is released and gravity causes the hammer to rotate and to strike a bowl, thereby causing a pleasant noise. The timer may be easily reset by simply inserting a new incense stick and resetting the hammer.




A primary object of the present invention is to provide a timer actuated by an incense stick burning to a given point on the stick, at which point a hammer is released and causes a pleasant alarm noise by striking a bowl.




A further object of the invention is to provide an easily resettable incense timer appropriate for use with meditation or other activities.




Another object of the invention is to provide an incense timer having a simple and cost effective design, but which is reliable and produces a pleasant alarm noise.




Further objects and advantages of the invention will become apparent from the following description and drawings wherein:

DETAILED DESCRIPTION OF THE DRAWINGS





FIGS. 1-4

illustrate a first embodiment of the invention wherein a metallic bowl


10


is provided and incense stick


20


is oriented on a vertical axis. However, it is understood that incense stick


20


could be mounted on an inclined axis as well. Incense stick


20


is carried by a holder


22


which is a generally rectangular shaped piece of ceramic or other suitable material carried by a recess


23


(

FIG. 3

) formed in hammer support stands


50


and


60


.




Hammer


30


may be made of different materials but wood is the preferred material. The first end


31


of hammer


30


carries a metallic rod


32


in a cylindrical bore


33


. The second end


34


rotates toward bowl


10


when hammer is released and strikes bowl


10


with side surface


35


near second end


34


.




Mounting means


40


is shown best in

FIGS. 3 and 4

and includes hammer support stand


50


and inclined upper surface


51


of hammer support stand


50


, bearing


41


carried by upper surface


51


and pin


42


carried by bearing


41


and extending into and fixedly attached to hammer


30


. Upper surface


51


is inclined at angle A to the horizontal. Hammer


30


is mounted to pin


41


at a point slightly closer to first end


31


so that the second end


34


is urged by gravitational forces to move towards bowl


10


as the hammer becomes free to rotate. Several recesses


23


,


24


and


25


are formed in hammer support stands


50


and


60


to provide different heights for incense stick holder


22


to achieve different lengths of time before the incense stick


20


burns to a given point


29


(

FIG. 3

) at which point the hammer


30


becomes released. By positioning the incense support plate


22


higher on hammer support stand


50


, more time elapses before a given incense stick burns to given point


29


to sound the alarm.




After hammer


30


strikes bowl


10


to make the pleasant alarm noise, it is easily reset. The user simply removes the burned incense stick


20


from incense stick holder


22


, rotates hammer


30


back to its first, retracted or cocked position shown in

FIG. 1

, and inserts a new incense stick in incense stick holder


22


.




As shown in

FIG. 3

, hammer


30


rotates on an axis


39


which forms an angle A with vertical axis


38


. Angle A ranges from 5° to 90°, but the preferred angle is 20°.





FIGS. 5 and 6

illustrate an alternate form of the invention wherein bowl


10


is struck by hammer


130


. Hammer


130


is mounted pivotally on a horizontal axis by elongated pin


141


which is carried by hammer support stand


150


. Elongated pin


141


lies on an axis parallel with incense stick


120


, and elongated pin


141


is longer than incense stick


120


. Base


190


carries bowl


10


and hammer support stand


150


. The first end


131


of hammer


130


carries a metallic rod


132


which may have a slight bend formed in it. Rod


132


is supported in its retracted position, shown in

FIG. 5

, by incense stick


120


which is mounted in a hole in support stand


150


on a horizontal axis parallel to the longitudinal axis on which elongated pin


141


lies. As incense stick


120


burns to a given point along its length, rod


132


is released and hammer


130


moves by gravity to its second position shown in

FIG. 6

where side surface


135


is about to contact bowl


10


. Hammer


130


may be placed at different locations along the length of elongated pin


141


in order that rod


132


rests at different points along incense stick


120


to allow variations in time before the alarm is sounded after the incense stick starts to burn. An ash collecting trough


180


is carried by support base


190


and extends lengthwise in the same direction as incense stick


120


and collects ashes dropped by the burning incense stick


120


. Hammer


130


comes to rest in a vertical position after striking bowl


10


.




Bowl


10


is preferably metal and hammer


30


is preferably wood. Rod


132


and pin


141


are preferably metal, but alternate materials may be used.
