Overhead baggage compartment with a lowerable trough
First Claim
1. An overhead baggage compartment, comprising a downwardly open housing with a first side member (4) and a second side member (4) spaced from said first side member, a luggage holding trough (3) tiltably mounted in said housing, first and second lever means (9, 10) forming pivotable quadrilateral first and second links, said first link connecting one end wall of said trough (3) to said first side member of said housing, said second link connecting the other end wall of said trough (3) to said second side member of said housing, each of said first and second links comprising an upper lever (9) and a lower lever (10), and a pneumatic spring means (14) provided for each of said first and second links, first and second fixed pivot points (5, 6) on each of said first and second side members (4) for journalling one end of said first link to said first side member and one end of said second link to said second side member, third and fourth movable pivot points (7, 8) on each of said end walls of said trough (3) for journalling the other end of said first link and of said second link to its respective end wall of said trough (3), a guide member (15) for movably securing one end of said pneumatic spring means (14) to the respective quadrilateral first and second link, at least one trough load weighing mechanism comprising a weighing lever (13), a spring (24) for biasing said weighing lever, and a weighing pin (25) connected to said trough (3) and cooperating with said weighing lever (13), and means (11, 12) connecting said weighing lever (13) to said pneumatic spring means for shifting said guide member (15) of said pneumatic spring means along at least one of said first and second links to such a position that a respective mechanical advantage of said pneumatic spring means corresponds substantially to a weight of said trough as determined by said trough load weighing mechanism.

Abstract
An overhead baggage compartment has a lowerable trough, especially for a passenger aircraft, wherein the trough is connected by two quadrilateral bellcrank type levers or links, with the side walls of the trough inside a box-like housing which is open at the bottom and also has two side walls. A substantial weight compensation is achieved by pneumatic springs, whereby each pneumatic spring (14) works on an adjustable attachment point on the corresponding quadrilateral bellcrank link through a guide roller 15. During loading of the trough 3, its weight is so determined and the pneumatic spring 14 is so swivelled by a weighing lever 13, that the guide roller 15 is placed on the corresponding quadrilateral bellcrank link at an attachment point chosen according to the determined weight. It is a special advantage that closing of the baggage compartment only requires a minimal manual force which is largely independent of the weight of the trough.
