Abstract
A turret indicator for a television receiver includes a stationary gear attached to a mounting base with a shaft passing through it. A rotatable carrier turret is mounted on the shaft and it carries five rotatable planetary indicator turrets which are programmed with channel numbers, five on each indicator turret to give a total of 25 indicating positions. When the rotatable carrier turret is rotated, the numerals on the indicator turrets appear sequentially at a viewing window in the television receiver cabinet.
Claims10
A turret indicator for providing numerical indications of relative rotational positions of a rotating member including, in combination:
- a rotatable carrier turret means rotatable to N predetermined equi-angular spaced rotational positions within each complete 360.degree. rotation thereof, where N is a positive integer greater than 1;
- means for rotating said carrier turret means;
- N planetary indicator turret members, each having N equi-angular spaced indicia portions thereon, each indicia portion associated with a segment comprising 360/N degrees of such planetary indicator turret member, and said N planetary indicator turret members being mounted on said rotatable carrier turret means and being spaced each 360/N degrees about the axis of rotation of said carrier turret means;
- and
- drive means responsive to the rotation of said rotatable carrier turret means to said spaced rotational position and coupled with said planetary indicator turret members for rotating each of said planetary indicator turret members 360n .+-. (360/N) degrees for each 360.degree. rotation of said carrier turret means, where n is any positive integer.
A turret indicator for a television receiver for providing channel number indications of sequential detented rotational positions of a tuner shaft including, in combination:
- a rotatable carrier turret mechanism coupled with said tuner shaft and rotatable to at least N predetermined equi-angular spaced rotational positions within each complete 360.degree. rotation thereof, where N is a positive integer greater than 1, and each of said N equi-angularly spaced rotational positions corresponds with successive detented rotational positions of said shaft;
- N planetary indicator turret members, each having N equi-angularly spaced indicia portions thereon, where each indicia portion indicates a different channel number and is associated with a segment comprising 360/N degrees of one of said planetary indicator turret members, said N planetary indicator turret members being attached to said rotatable carrier turret mechanism and being spaced each 360/N degrees about the axis of rotation of said carrier turret mechanism;
- and
- drive means responsive to the rotation of said rotatable carrier turret mechanism to each sequential detented position of the tuner shaft and coupled with said planetary indicator turret members for rotating each of said planetary indicator turret members 360n .+-. (360/N) degrees for each 360.degree. of rotation of said carrier turret mechanism, where n is any positive integer.
