Abstract

A virtual touch screen switch includes a push window disposed over a display assembly. The transparent push window functions similar to a toggle switch, while enabling touch screen functionality. In a preferred arrangement, the push window is disposed in a display opening of an electronic apparatus and is pivotable between a neutral position and one or more actuating positions where an actuator mounted to the push window actuates a PCB switch. With this arrangement, function keys from the electronic apparatus can be eliminated with a toggle-type switch arrangement, thereby reducing the apparatus size while maintaining reasonable manufacturing costs.

Claims

1. A virtual touch screen switch comprising:

a display assembly comprising a display apparatus;

a push window disposed over said display assembly, said push window being substantially transparent, wherein said push window is pivotable relative to said display assembly; and

at least one actuator coupled with said push window.

2. A virtual touch screen switch according to claim 1, further comprising a spring member disposed engaging said push window, said spring member urging said push window toward a neutral position.

3. A virtual touch screen switch according to claim 2, wherein said spring member is disposed between said push window and said display assembly.

4. A virtual touch screen switch according to claim 2, wherein said spring member comprises a rubber gasket disposed surrounding said display assembly.

5. A virtual touch screen switch according to claim 1, further comprising a light guide disposed adjacent said display assembly on a side of said display assembly opposite from said push window, said light guide comprising a hinge connector, wherein said push window comprises a hinge pin cooperating with said hinge connector.

6. A virtual touch screen switch according to claim 5, wherein said light guide comprises a pair of hinge connectors disposed substantially along a central longitudinal axis of the switch, the virtual touch screen switch further comprising:

a pair of hinge pins attached to said push window and correspondingly disposed along said central longitudinal axis such that said push window is pivotable about said central longitudinal axis between a left position, a neutral position and a right position; and

a pair of actuators coupled with said push window.

7. A virtual touch screen switch according to claim 1, wherein said push window is pivotable about a longitudinal axis between an actuate position and a neutral position, the virtual touch screen switch comprising one actuator coupled with said push window.

8. A virtual touch screen switch according to claim 1, wherein said push window is pivotable about a central longitudinal axis of the switch between a left position, a neutral position and a right position, the virtual touch screen switch comprising a pair of actuators coupled with said push window.

9. A virtual touch screen switch according to claim 1, wherein said push window is pivotable about a central longitudinal axis of the switch between a left position, a neutral position and a right position and about a central lateral axis between a forward position, a neutral position and a rearward position, the virtual touch screen switch comprising four actuators coupled with said push window.

10. A virtual touch screen switch according to claim 1, wherein said push window is pivotable about a centrally disposed pivot between a left forward position, a left rearward position, a right forward position, a right rearward position, and a neutral position, the virtual touch screen switch comprising four actuators coupled with said push window.

11. A virtual touch screen switch according to claim 1, wherein said display apparatus is one of an LCD and an LED.

12. A cellular phone comprising:

a phone casing housing phone components, said phone casing having a display opening therein;

a printed circuit board (PCB) operatively coupling the phone components;

a display assembly disposed adjacent said display opening;

a push window disposed over said display assembly in said display opening, said push window being substantially transparent, wherein said push window is pivotable relative to said display assembly; and

at least one actuator coupled with said push window that actuates a switch on said PCB in accordance with a position of said push window.

13. A cellular phone according to claim 12, further comprising a first spring member disposed engaging said push window, said first spring member urging said push window toward a neutral position.

14. A cellular phone according to claim 13, wherein said first spring member is disposed between said push window and said display assembly.

15. A cellular phone according to claim 13, further comprising a second spring member disposed between said push window and said phone casing.

16. A cellular phone according to claim 12, further comprising a light guide disposed adjacent said display assembly on a side of said display assembly opposite from said push window, said light guide comprising a hinge connector, wherein said push window comprises a hinge pin cooperating with said hinge connector.

17. A cellular phone according to claim 16, wherein said light guide comprises a pair of hinge connectors disposed substantially along a central longitudinal axis of the switch, the cellular phone further comprising:

a pair of hinge pins attached to said push window and correspondingly disposed along said central longitudinal axis such that said push window is pivotable about said central longitudinal axis between a left position, a neutral position and a right position; and

a pair of actuators coupled with said push window, said actuators actuating corresponding switches on said PCB in said left position and said right position, respectively.

18. A cellular phone according to claim 12, wherein said push window is pivotable about a longitudinal axis between an actuate position and a neutral position, the cellular phone comprising one actuator coupled with said push window that actuates the switch on said PCB in said actuate position.

19. A cellular phone according to claim 12, wherein said push window is pivotable about a central longitudinal axis between a left position, a neutral position and a right position, the cellular phone comprising a pair of actuators coupled with said push window that actuate corresponding switches on said PCB in said left position and said right position, respectively.

20. A cellular phone according to claim 12, wherein said push window is pivotable about a central longitudinal axis of the switch between a left position, a neutral position and a right position and about a central lateral axis between a forward position, a neutral position and a rearward position, the cellular phone comprising four actuators coupled with said push window that actuate corresponding switches on said PCB in said left position, said right position, said forward position and said rearward position, respectively.

21. A cellular phone according to claim 12, wherein said push window is pivotable about a centrally disposed pivot between a left forward position, a left rearward position, a right forward position, a right rearward position, and a neutral position, the cellular phone comprising four actuators coupled with said push window that actuate corresponding switches on said PCB in said left forward position, said left rearward position, said right forward position, and said right rearward position, respectively.
