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.
The foregoing description of the invention has been presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise form disclosed. Modifications and variations are possible in light of the above teaching. The embodiments were chosen and described to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best use the invention in various embodiments and with various modifications suited to the particular use contemplated. The scope of the invention is to be defined by the following claims.
