Title:
HINGE FOR EXPANDING/CLOSING SOLAR PANEL OR REFLECTOR
Document Type and Number:
Japanese Patent JP3145974
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To guarantee the same expansion moment for an expansion full continuous time by storing a part of the expansion energy of a helical spring in a twist spring by the shape of a sliding cam for the first half of an expansion time and supplying this stored energy to motion again for the second half of the expansion time.
SOLUTION: An insertion bolt 8 is pushed into a groove 12 existing in the end part of a sliding cam 5a by a twist spring 9, and thereby a fork 3 is locked together with a bearing support body 2. The sliding cam 5a has a gradually increased tilt angle in its starting end, and this tilt angle is reduced again from the center of the sliding cam 5a to the groove 12. By this shape of the sliding cam 5a, for the first half of the expansion of the fork 3, a part of the expansion energy of a helical spring 6 is stored in the twist spring 9. For the second half of the expansion, this stored energy is passed through the sliding cam 5a and supplied again to expansion moment.
