Abstract
Gobo wheel assembly has multiple gobo devices on a rotatable wheel. A central sun gear can rotate all the gobos. The gobos can be inserted and released from the wheel assembly.
Claims13
A gobo wheel assembly, comprising:
- a gobo wheel, having a plurality of gobo wheel holding parts, which each are spaced from one another, and which each hold gobos, forming a plurality of different surfaces for holding a plurality of different gobos, said gobo wheel having a toothed outer wheel which is rotatable;
- and
- a gobo holding part, holding a gobo, and having first and second movable spring parts which are movable and are attached to said gobo holding part, and having surfaces which each fit in said gobo wheel holding parts on said gobo wheel and are insertable and removable from said gobo wheel, said first and second movable spring parts holding said gobo into one of said surfaces on said gobo wheel, where said first and second spring holding parts respectively hold first and second sides of said gobo holding parts into said gobo wheel holding part, but do not extend completely around said gobo holding part, wherein said first and second spring holding parts are coupled to a movable toothed outer wheel part of said gobo holding part, which when said spring holding parts are inserted, presses the toothed outer wheel of said gobo holding part against the toothed outer wheel of said gobo wheel, and allows said gobo wheel to rotate when said toothed outer wheel of said gobo wheel rotates, and without rotating said spring parts.
A method of holding and removing gobos from a holder, comprising:
- moving first and second spring parts on a gobo holding wheel against their spring force;
- while holding said first and second spring parts against said spring force, removing a gobo holder from said gobo holding wheel that was held by said first and second spring parts;
- inserting a new gobo holder on said gobo holding wheel while holding said first and second spring parts against said spring force;
- and
- using said spring parts to hold an unmovable part of said new gobo wheel, at two surfaces of said new gobo wheel;
- and
- rotating a moving part of said new gobo wheel while said unmovable part is held to said gobo holding wheel and said unmovable part does not rotate while said moving part rotates.
