Abstract

A lighted serving tray includes a tray body having platter portion and a chamber portion attached to the underside of the platter portion. The chamber portion houses a plurality of lights which are installed in a perimetric wall thereof, a battery pack coupled to a recharging jack installed within the perimetric wall, and coupled to each of the lights via circuit elements, which includes at least one normally-on, on-off switch installed in a lower panel of the chamber portion, and which may include a flashing circuit. For a preferred embodiment of the invention, each of the lights is a light-emitting diode (LED) so as to minimize current drain. Also for the preferred embodiment of the invention, each of the on-off switches is installed within its own recess in the lower panel in such a manner that a movable activating element of the switch extends below a lower major surface of the lower panel. Thus, when the serving tray is placed on a substantially planar surface, the activating element is moved to an "off" position, thereby cutting power to the lights and to the flashing circuit.

Claims

1. A lighted serving tray comprising:

a tray body having

a platter portion with a raised perimetric rim, a lower surface, and an upper serving surface on which food and drinks may be carried; and

a chamber portion having a collar portion, a perimetric wall portion, and a bottom panel portion having a lower major surface, said collar portion being attached to the lower surface of said platter portion, thereby forming an enclosed chamber bounded by the platter portion, the perimetric wall portion and the bottom panel portion;

a plurality of light emitting diodes (LEDs) installed within apertures formed within the perimetric wall portion, such that the light-emitting end of each LED is outside the chamber;

a battery pack coupled to each LED;

a flasher circuit interposed between the battery pack and each of the LEDs;

at least one disconnect switch interposed between the battery pack and said flasher circuit, said disconnect switch having an activating element, said switch being installed within said bottom panel portion so that said activating element extends below said major surface so that when the tray is placed upon a substantially planar surface, said activating element is displaced, thereby cutting off power to said flasher circuit and said LEDs.

2. The lighted serving tray of claim 1, which further comprises a bypass switch which may be selectively activated to either decouple the flasher circuit from the LEDs and thereby provide continuous power to the LEDs, or couple the flasher circuit to the LEDs and thereby provide intermittent power to the LEDs.

3. The lighted serving tray of claim 1, which further comprises a jack coupled to said recharging circuit, which permits connection of said recharging circuit to an external power source.

4. The lighted serving tray of claim 1, wherein said platter portion is circular.

5. The lighted serving tray of claim 1, wherein said platter portion is rectangular with rounded corners.

6. The lighted serving tray of claim 1, which further comprises a plurality of screw-type fasteners, which are employed to secure said chamber portion to said platter portion.

7. The lighted serving tray of claim 1, wherein each of said disconnect switches is installed within a recess in said bottom panel portion.

8. The lighted serving tray of claim 1, which further comprises a resilient, slip-resistant layer overlying said serving surface portion.

9. A lighted serving tray comprising:

a tray body having a platter portion, a lower surface and an upper surface on which drinks and food may be carried, a perimetric wall portion attached to said lower surface, and a bottom panel portion continuous with said wall portion, said bottom panel portion having a lower major surface having recesses therein, said platter portion, said perimetric wall portion and said bottom panel portion forming a chamber;

a plurality of light emitting diodes (LEDs) installed within apertures formed within the perimetric wall portion, such that the light-emitting end of each LED is outside the chamber;

a battery pack coupled to each LED, said battery pack located within said chamber;

a flasher circuit interposed between the battery pack and each of the LEDs, said flasher circuit located within said chamber;

one disconnect switch installed within each recess, said disconnect switches coupled in series between said battery pack and said flasher circuit, each of said disconnect switches activatable by placing the serving tray on a substantially flat surface.

10. The lighted serving tray of claim 9, which further comprises a bypass switch which may be selectively activated to either decouple the flasher circuit from the LEDs and thereby provide continuous power to the LEDs, or couple the flasher circuit to the LEDs and thereby provide intermittent power to the LEDs.

11. The lighted serving tray of claim 9, which further comprises a jack coupled to said recharging circuit, which permits connection of said recharging circuit to an external power source.

12. The lighted serving tray of claim 9, wherein said platter portion is circular.

13. The lighted serving tray of claim 9, wherein said platter portion is rectangular with rounded corners.

14. The lighted serving tray of claim 9, which further comprises a resilient, slip-resistant layer overlying said serving surface portion.

15. The lighted serving tray of claim 14, wherein said resilient slip-resistant layer is made from cork.

16. The lighted serving tray of claim 9, wherein said platter portion has a raised perimetric rim.

17. A lighted serving tray comprising:

a platter having an upper serving surface and a lower surface;

an enclosure attached to the lower surface of said platter, said enclosure having a perimetric wall and a bottom panel having a lower major surface;

a plurality of LEDs installed within said perimetric wall;

a battery pack located within said enclosure coupled to each LED;

at least one disconnect switch installed within said bottom panel, said disconnect switch having an activating element extending below said lower major surface which is displaced to activate said disconnect switch when said tray is placed on a substantially planar horizontal surface, thereby decoupling said battery from each of said LEDs.

18. The lighted serving tray of claim 17, which further comprises a flashing circuit located within said enclosure, said flashing circuit being interposed between said battery and at least some of said LEDs in order to provide intermittent power to said some LEDs.

19. The lighted serving tray of claim 17, wherein each disconnect switch is installed within a recess within said bottom panel.

20. The lighted serving tray of claim 17, which further comprises a charging circuit installed within said recess and a jack installed within said perimetric wall, said charging circuit coupled to both said jack and said battery pack, said battery pack being rechargeable by connecting said jack to an external power source.
