Title:
ROTARY DECORATION
Document Type and Number:
Japanese Patent JP3197824
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize a rotary decoration for decoration clock which can be driven with low power by reducing the frictional load while reducing the size.
SOLUTION: A tubular rotary base 3 is secured to the rotary shaft 1a of a body 1 to be driven synchronously with a clock while covering a sun gear 2 arranged about the rotary shaft 1a. A rotary shaft 7 projecting from the upper plate 3a of the rotary base 3 and fixed, to one end thereof, with a decoration 6 is fixed rotatably to the upper plate 3a and a planetary gear 8 meshing the sun gear 1 is secured to the rotary shaft 7. The rotary shaft 7 is born with light friction, at the other end thereof, by a lower plate 3b through the magnetic repellence between a magnet 12 secured to the planetary gear 8 and a magnet 13 secured to the lower plate 3b. The planetary gear 8 spins while revolving about the sun gear 2 when the sun gear 2 turns. The rotary shaft 7 fixed with the decoration 6 turns smoothly under a state of low frictional load spins the decoration 6 smoothly while revolving with low power consumption on the upper plate 3a of the rotary base 3 so that a decoration clock exhibits a unique decoration effect.
