Abstract

A locking mechanism for tying down a piece of freight on a loading floor in an aircraft has a housing (11) recessed in the loading floor. A latch operating member (1) and a latching member (10) are journalled in the housing to tilt toward each other or away from each other. Follower cams (16) of the latching member (10) ride in respective cam guide tracks (15) of the latch operating member (1). A tension spring (20) tends to bias the latching member (10) and the latch operating member (1) in opposite directions in a freight latching position or into a recessed beyond dead center position. Stop members (17, 18) are so positioned on the latch operating member and on the latching member that the latter cannot be tilted without activating the latch operating member which can be rolled over by a piece of freight in one direction when projecting from the housing and in the other direction when recessed into the housing.
