Abstract

A fader wheel assembly for a lighting control console includes a fader wheel having a single hub mounted at an acute angle to the top wall of the console. The inclined orientation positions approximately half of smooth, rounded outer wall and rim surfaces above the console top wall in an arrangement that is comfortable for the user. A single bearing locates the wheel as well as a transducer that is supported essentially only by its attachment to the fader wheel. Resilient arms lightly hold the transducer in position.

Claims

1. A fader wheel assembly for a lighting control console having a top wall with a fader wheel aperture, said fader wheel assembly comprising:

a wheel having a rotational axis and opposed inner and outer sides symmetrical about said axis;

said inner side including a projecting mounting hub located at said axis;

a mounting assembly for mounting said wheel for rotation about said axis, said mounting assembly including a bearing means located under the top wall adjacent the aperture for supporting said hub and wheel for rotational motion;

said mounting system supporting said wheel with a segment of said wheel projecting upward through the aperture;

said fader wheel assembly being characterized by;

said mounting system supporting said wheel with said axis being disposed at an angle to the top wall.

2. The fader wheel assembly of claim 1, said outer side of said wheel including a continuous, uninterrupted plane smoothly extending across and around said axis.

3. The fader wheel assembly of claim 1, said axis being disposed at an acute angle to said top wall.

4. The fader wheel assembly of claim 2, approximately half of said continuous, uninterrupted plane being accessible above the top wall.

5. The fader wheel assembly of claim 2, said continuous, uninterrupted plane being convex.

6. The fader wheel assembly of claim 5, said continuous, uninterrupted plane being a segment of a sphere.

7. The fader wheel assembly of claim 2, said inner side having a convex, conical portion disposed approximately perpendicular to the top wall.

8. The fader wheel assembly of claim 7, said wheel including a continuously rounded rim joining said inner and outer sides.

9. The fader wheel assembly of claim 1, further comprising a motion sensing transducer connected to said hub.

10. The fader wheel assembly of claim 9, said wheel and said transducer being disposed at opposite sides of said bearing means.

11. The fader wheel assembly of claim 10 said mounting means further including a mounting bracket for supporting said bearing means.

12. The fader wheel assembly of claim 11 further comprising means connected between said bracket and said transducer for preventing rotation of said transducer while permitting movement of said transducer relative to said bracket.

13. A fader wheel assembly for mounting to a wall of a lighting control console, said assembly comprising:

a massive fader wheel having a diameter in excess of about two inches;

an axial hub projecting from one side of said wheel;

a bearing rotatably supporting said hub;

a bearing support engaging said bearing and adapted to be attached to the wall of the lighting control console;

a rotation sensing transducer having a housing and an input member rotatable relative to said housing;

said input member being coaxial with and drivingly connected to said hub;

said fader wheel assembly being characterized by;

said bearing support and said bearing supporting the mass of said wheel;

said driving connection of said hub to input member providing substantially the entire support of said transducer; and

a retainer connected between said support and said transducer housing to prevent rotation of said housing;

said retainer including an arm having a free end, said arm engaging said transducer housing.

14. The fader wheel assembly of claim 13, said bearing comprising a tubular sleeve.

15. The fader wheel assembly of claim 13, said bearing support including a rigid flange fixed to said bearing and adapted to be fixed to the lighting control console wall.

16. The fader wheel assembly of claim 13, said arm being resilient.

17. A fader wheel assembly for mounting to a wall of a lighting control console, said assembly comprising:

a massive fader wheel having a diameter in excess of about two inches;

an axial hub projecting from one side of said wheel;

a bearing rotatably supporting said hub;

a bearing support engaging said bearing and adapted to be attached to the wall of the lighting control console;

a rotation sensing transducer having a housing and an input member rotatable relative to said housing;

said input member being coaxial with and drivingly connected to said hub;

said fader wheel assembly being characterized by;

said bearing support and said bearing supporting the mass of said wheel;

said driving connection of said hub to input member providing substantially the entire support of said transducer; and

a retainer connected between said support and said transducer housing to prevent rotation of said housing;

said retainer including a pair of arms engaging opposed portions of said transducer housing.

18. The fader wheel assembly of claim 17, said arms being resilient.

19. The fader wheel assembly of claim 18, said bearing support including rigid mounting flange means fixed to said bearing and adapted to be fixed to said lighting control console wall, said resilient arms projecting from said rigid mounting flange means.
