Title:
ROTARY DECORATION
Document Type and Number:
Japanese Patent JP3197825
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a rotary decoration for a decoration clock in which a decoration can be fixed easily at a predetermined angle in the radial direction to a rotary base.
SOLUTION: A rotary base 3 is secured to the rotary shaft 1a of a driver 1 synchronized with a clock while covering a sun gear 2 arranged about the rotary shaft 1a. A rotary shaft 7 having projecting end secured with a decoration 6 is fixed rotatably to the upper plate 3a of the rotary base 3. The rotary shaft 7 is secured with a planetary gear 8 meshing the sun gear 2 and a magnet 12 is secured to the planetary gear 8 while a magnet 13 is secured to the lower plate 3b of the rotary base 3 in order to hold the rotary shaft 7 rotatably at the other end thereof. The planetary gear 8 is held while being locked on the upper plate 3a of the rotary base 3 before the decoration 6 is fixed to the rotary shaft 7 by the repulsive forces of the magnets 12, 13. When the decoration 6 is secured to a predetermined angular position of the D cut section 7a of the rotary shaft 7, the planetary gear 8 can turn freely with the weight of the decorator 6 which can thereby be secured to a predetermined angular position of the rotary shaft 7 through a simple operation.
