Pivoted damper blade and pin therefor |
摘要 |
A pivoted blade which has a centrally positioned V-shaped pin-receiving depression combined with a slidable mounting pin which is releasably secured within the depression in the blade. This pin comprises an elongated element which is circular in cross-section at one end thereof, and its other end is flattened at one side and of V-shape on the other side. The other end of the pin has a centrally positioned hole extending therethrough with this hole being centrally disposed with respect to the flattened side and extending through the apex of the V-shaped side. This centrally positioned hole is longer than it is wide with the longer cross-section extending longitudinally of the pin. The mounting pin is mounted at a side margin of the blade with the V-shaped portion of the pin fitting into the V-shaped depression in the blade and with the end of circular cross-section extending beyond the side margin of the blade. A bolt extends through a hole in the apex of the V-shaped depression in the blade and through the hole in the pin, and a nut is associated with the free end of the bolt to lock the pin to the blade.
