Joystick thumb cushion

1. A cushioned attachment for a user-manipulatable actuator of a controller device, the actuator having an actuator top portion supported on a movable shaft and having top and side surfaces, comprising:

an elastomeric body including a hollow interior defined by a side surface connecting a closed top portion and a partly open bottom portion, the partly open bottom portion extending radially inward from the side surface to define a bottom portion opening;

a divider including a flange positioned in the interior of the body between the closed top and partly open bottom portions and extending radially inward from the side surface, the divider having opposite first and second flange surfaces and forming first and second interior cavities separated by a divider opening that provides a fluid communication interconnection between them, the first interior cavity having a depth defined by a distance between the partly open bottom portion and the first flange surface of the divider, and the second interior cavity having a depth defined by a distance between the closed top portion and the second flange surface of the divider; and

the bottom portion opening and the depth of the first interior cavity being sized to seat the actuator top portion in the first interior cavity upon placement of the cushioned attachment over the top and side surfaces of the actuator top portion, and the divider opening and the depth of the second interior cavity being sized to provide for the user a sealed fluid cushion when the actuator top portion is seated.

2. The cushioned attachment of claim 1 , in which the sealed fluid cushion is a sealed air cushion.

3. The cushioned attachment of claim 1 , in which the elastomeric body is a unitary article of which the partly open bottom portion and the divider are integral parts.

4. The cushioned attachment of claim 1 , in which the partly open bottom portion is of annular shape and the bottom portion opening is a round hole.

5. The cushioned attachment of claim 1 , in which the divider is of annular shape and the divider opening is a round hole.

6. The cushioned attachment of claim 1 , in which the body is of generally cylindrical shape, and in which the partly open bottom portion and the divider are each of annular shape.

7. The cushioned attachment of claim 6 , in which the elastomeric body is a unitary article of which the partly open bottom portion and the divider are integral parts.

8. The cushioned attachment of claim 1 , in which the elastomeric body includes silicone material.

9. The cushioned attachment of claim 1 , in which the elastomeric body includes one of rubber or latex material.

10. The cushioned attachment of claim 1 , in which the bottom portion opening and the divider opening are of the same size.

11. The cushioned attachment of claim 1 , in which the flange is of annular shape.
