Title:
SINGLE DIRECTION ROTATION BRAKE HAVING LOW FRICTION RESISTANCE FORCE
Document Type and Number:
Japanese Patent JP2019100450
Kind Code:
A
Abstract:
To provide a single direction rotation brake having friction resistance force.SOLUTION: There are provided a rotation brake main body, several roller rods, two interlock annular pieces and at least one position returning means. Several storing grooves corresponding to each of the roller rods are arranged in an annular manner for every specified interval, each of both ends of the roller rod is provided with a position restriction protruded column, each of the two interlock annular pieces is arranged at both ends of the roller rod and at the same time the two interlock annular pieces can produce a rotation of desired angle, when several interlock holes are arranged on said interlock annular pieces and the position restriction protruded column passes through the interlock hole and the interlock annular pieces produce a rotation of predetermined angle, all the roller rods are synchronously operated, even if the number of roller rods is increased, it is not necessary to use other same number of springs or magnets, the frictional resistance force in an idling rotation can be substantially decreased and in turn an incremental force can also be attained by installation to increase the number of roller rods.SELECTED DRAWING: Figure 7
