OVERHEAD STOWAGE BIN MECHANISM

摘要

The bin mechanism allows the bin (24) to be manually moved without any effort from a stowed position to a loading position. For this purpose, the support arms (20) and (22) are provided with specially designed self-aligning bearings (14) and (18). Each bearing (14) or (18) has three parts: an interior bin mounted needle bearing axle unit or housing (52); an exterior bin mounted nut (86); and an axle retainer unit (62). Installation or repair is accomplished from the interior of the bin (24) by the turning of the bearing axle bolt (54) which is threaded unto either the arm (20) or the arm (22). Disconnection of the bolt (54) from the arms (20) or (22) is accomplished while the bin (24) is in its loading position and momentarily arrested by a pin (44) connecting both arms (20) and (22). However, the bolt does not disconnect from the mechanism but is automatically gripped by a retainer washer (68) for retention thereof inside of the needle housing (52). Self-aligning and linear control is accomplished by the substantially wide needle bearing housing (52) providing full non-rocking support to and about the solidly mounted axle bolt (54).
