Abstract

A lighting toothbrush (20) includes a body (22) which carries a motion-sensing switch (26), a plurality of light emitting devices (30), a timer (32), and a battery (34). As lighting toothbrush (20) is oscillated, motion switch (26) closes sending a signal to timer (32) which applies a voltage waveform (50) to lights (30). In a preferred embodiment, timer (32) causes lights (30) to be sequentially illuminated thereby producing a "twinkle" effect. Also, in a preferred embodiment, all of the components are permanently encapsulated within transparent body (22).

Claims

1. A lighting toothbrush, comprising:

an elongated body having a longitudinal axis;

a motion switch carried by said body, said motion switch having a motion-sensing axis, said motion-sensing axis substantially parallel to said longitudinal axis;

at least one light emitting device carried by said body;

a timer carried by said body, said motion switch and said at least one light emitting device connected to said timer; and

,

so that when said body is oscillated substantially along said longitudinal axis, said motion switch closes actuating said timer which in turn applies a voltage waveform to said at least one light emitting device for a predetermined period of time.

2. A lighting toothbrush according to claim 1, further including:

said motion switch, said at least one light emitting device, and said timer encapsulated within said body.

3. A lighting toothbrush according to claim 1, further including:

said body being transparent.

4. A lighting toothbrush according to claim 1, further including:

a power source carried by said body, said power source connected to said timer.

5. A lighting toothbrush according to claim 1, further including:

said predetermined period of time being about 5 seconds.

6. A lighting toothbrush according to claim 1, further including:

a plurality of light emitting devices carried by said body.

7. A lighting toothbrush according to claim 6, further including:

said timer applying said voltage waveform to each of said plurality of light emitting devices in time-phased sequence.

8. A lighting toothbrush according to claim 6, further including:

said voltage waveform causing each said light emitting device to be illuminated for a predetermined duration.

9. A lighting toothbrush according to claim 1, further including:

said motion switch having a degree of oscillatory motion required to close.

10. A lighting toothbrush according to claim 1, said motion switch further including:

a movable conductor having a weight;

a first pole;

a second pole;

a spring oriented along said motion-sensing axis, said spring biasing said movable conductor away from said first pole; and

,

so that when said body is oscillated substantially along said motion-sensing axis, said weight of said movable conductor overcomes said biasing of said spring, and said movable conductor contacts both said first pole and said second pole, thereby closing said motion switch.

11. A lighting toothbrush according to claim 10, further including:

said spring having a stiffness; and

,

said stiffness of said spring establishing said degree of oscillatory motion required to close said motion switch.

12. A lighting toothbrush according to claim 1, further including:

a power source connected to said timer;

a plurality of light emitting devices;

said motion switch, said plurality of light emitting devices, said timer, and said power source encapsulated within said body;

said body being transparent; and

,

said timer applying said voltage waveform to each of said plurality of light emitting devices in time-phased relationship.

13. A lighting toothbrush, comprising:

an elongated body having an end and a longitudinal axis;

bristles disposed near said end, said bristles defining a bristle axis, said bristle axis substantially perpendicular to said longitudinal axis;

a motion switch carried by said body, said motion switch having a motion-sensing axis, said motion-sensing axis substantially perpendicular to both said longitudinal axis and said bristle axis;

at least one light emitting device carried by said body;

a timer carried by said body, said motion switch and said at least one light emitting device connected to said timer; and

,

so that when said body is oscillated substantially along said motion-sensing axis, said motion switch closes actuating said timer which in turn applies a voltage waveform to said at least one light emitting device for a predetermined period of time.

14. A lighting toothbrush according to claim 13, further including:

said motion switch, said at least one light emitting device, and said timer encapsulated within said body.

15. A lighting toothbrush according to claim 13, further including:

said body being transparent.

16. A lighting toothbrush according to claim 13, further including:

a power source carried by said body, said power source connected to said timer.

17. A lighting toothbrush according to claim 13, further including:

a plurality of light emitting devices carried by said body.

18. A lighting toothbrush according to claim 17, further including:

said timer applying said voltage waveform to each of said plurality of light emitting devices in time-phased sequence.

19. A method for brushing teeth, comprising:

providing a toothbrush having an elongated body having a longitudinal axis, a motion switch carried by said body, said motion switch having a motion-sensing axis, said motion-sensing axis substantially parallel to said longitudinal axis, at least one light emitting device carried by said body, a timer carried by said body, said timer providing a voltage waveform, said motion switch and said at least one light emitting device connected to said timer; and

,

oscillating said body substantially along said longitudinal axis, so that said motion switch closes actuating said timer which in turn applies said voltage waveform to said at least one light emitting device for a predetermined period of time.

20. A method for brushing teeth, comprising:

providing a toothbrush having a transparent elongated body having an end and a longitudinal axis, bristles disposed near said end, said bristles oriented parallel to a bristle axis, said bristle axis substantially perpendicular to said longitudinal axis, a motion switch carried by said body, said motion switch having a motion-sensing axis, said motion-sensing axis substantially perpendicular to both said longitudinal axis and said bristle axis, at least one light emitting device carried by said body, a timer carried by said body, said timer providing a voltage waveform, said motion switch and said at least one light emitting device connected to said timer; and

,

oscillating said body substantially along said motion-sensing axis, so that said motion switch closes actuating said timer which in turn applies said voltage waveform to said at least one light emitting device for a predetermined period of time.
