Abstract
A quick-change track lock for securing interior-design articles on C-shaped retaining tracks on a floor or walls in an airplane, a helicopter or a spacecraft includes a main body, a detent member for fixing the track lock in a retaining track, a locking body having mushroom-shaped locking members operable for engagement with undercut portions of the retaining track and a pivotable actuating lever cooperating with the locking body to displace the latter relative to the main body. The locking body is guided in the main body such that a distance between each locking member and clamping edges of the main body becomes smaller when the locking body is displaced from one placed position to a locked position.
Claims15
Quick-change track lock for securing interior-design articles or load-restraining members on C-shaped retaining tracks laid in a floor or on a wall of an interior in an airplane, a helicopter or spacecraft, the lock comprising a main body (1) having clamping edges (22);
- at least one detent member (19, 40, 59, 67) associated with the main body (1) for fixing the track lock longitudinally in a retaining track;
- a locking body (4) guided in the main body (1) and displaceable in a longitudinal direction of the track lock, said locking body (4) including at least one mushroom-shaped locking member (20) adapted to engage undercut portions of the retaining track;
- an actuating lever (10) pivotally attached to said main body and coacting with the locking body (4) in such a manner that, when the actuating lever (10) is pivoted, the locking body (4) is displaced with respect to the main body (1) in a longitudinal direction thereof;
- and means for guiding the locking body (4) in the main body (1) in such a manner that a distance between each locking member (20) and the clamping edges (22) of the main body (1) becomes smaller when the locking body is displaced from an as-placed position into a locked position, to establish an antirattle connection.
