Abstract

Disclosed herein is an improved joy stick control including a control rod interrelated with four switches so as to enable the control of movements in eight different directions. In a further aspect, the present invention includes a fire button located below the switches associated with the control rod and above indentations formed in the handle for the fingers. Each of the switches associated with the control rod includes a stationary upper contact and a movable lower contact with the lower contacts of the switches being operatively connected to the control rod.

Claims

1. An improved joystick control device comprising:

(a) an upper housing portion;

(b) a control rod extending upwardly from said upper housing portion;

(c) a hand grip held housing portion depending downwardly from said upper housing portion; and

(d) switch means in said upper housing portion, said switch means having actuating means facing downwardly in a direction substantially opposite to the direction of elongation of said control rod and operatively connected to said control rod by a movable plate means whereby controlled movement of said control rod selectively actuates said switch means.

2. The invention of claim 1, wherein said upper housing portion is bulbous.

3. The invention of claim 1, wherein said hand grip held housing portion has a fire button mounted thereto.

4. The invention of claim 1, wherein said switch means includes at least one switch device including:

(a) a switch housing fixedly connected to said upper housing portion; and

(b) a pushbutton comprising said actuating means and operatively connected to said rod.

5. The invention of claim 4, wherein said switch means comprises four such switch devices, the respective switch housings thereof being mounted on a top function plate and the pushbuttons thereof being engaged to a bottom function plate comprising said movable plate means, said top function plate being fixedly connected to said upper housing portion and said control rod being rigidly connected to said bottom function plate.

6. The invention of claim 5, wherein each said push button is resiliently biased in a direction opening each said switch device.

7. The invention of claim 5, wherein said top function plate has a hole therethrough through which said control rod extends.

8. The invention of claim 7, further including a spring mounted between said top function plate and a retainer mounted on said control rod above said top function plate.

9. A switch mechanism for a joystick comprising:

(a) a housing portion;

(b) a top plate fixedly mounted to said housing portion;

(c) a control rod;

(d) a bottom plate rigidly connected to said control rod;

(e) said top plate having a hole therethrough through which said control rod extends; and

(f) a plurality of switches, each of said switches including a switch housing inversely mounted to said top plate in a direction opposite to the direction of elongation of said control rod and a pushbutton engaging said bottom plate.

10. The invention of claim 9, wherein said plurality of switches includes four switches.

11. The invention of claim 9, wherein said control rod includes a retainer thereon above said top plate and further including spring means interposed between said top plate and said retainer.

12. The invention of claim 9, wherein each said pushbutton is resiliently biased to an open position of said switch.
