A locking mechanism () and a lock () are provided. The locking mechanism () comprises a push-button () connected to a freewheel () via a traction cable, with the freewheel being connected to a drive device () of the lock (). A baggage compartment in the cabin of an airplane usually comprises two locks () of this type which can be unlocked by the push-button (). A freewheel () arranged between the push-button () and the lock () ensures that the push-button () remains in a pushed position as long as each lock () allocated to the baggage compartment is not in a correctly locked position. It can be identified from the position of the push-button of the baggage compartment whether both locks of the baggage compartment are correctly snapped in.

Locking mechanism for a housing and lock suitable therefor

An aircraft luggage box lock includes a stationary housing and a cover moveable about a rotary axis. The lock includes a locking pin device mountable on the housing, having two parallel locking pins, a catch mountable on the cover having two locking hooks pivotable about a pivot axis for receiving the pins for locking the lock, and a manually actuatable drive device for jointly pivoting the locking hooks away from the locking pins for unlocking the lock. The drive device has a gear rack and a sliding element linearly displaceable against pressure of a spring element. The locking hooks are connected to the gear rack or the sliding element by a knee lever hinged to the closing hook adjacent to the pivot axis thereof in such a way that the lock is openable only by tensile force acting on the hinged point of the knee lever on the locking hook.

A retaining cam () for a rotatable fastener for connecting components () is provided. The retaining cam () has a housing () pivotally supported on a base plate (), by which the retaining cam () can be fixedly connected to one () of the components (). A screw () is secured rotationally fixed in the housing (). A fastener bolt () rotatably connected to another () of the components () can be screwed onto the screw (). Spring elements are associated with the screw () for generating an elastic pretension for securing the fastener bolt () against rotation. The housing () is pivotally supported on the base plate () by a spherical washer (). An angle deviation between the center axes of the retaining cam () and the fastener bolt () can be compensated for by pivoting the retaining cam on the spherical washer () while maintaining full-surface contact of the retaining cam ().

Retaining cam for a rotary fastener

A hinge for a packaging or cargo box or the like, having a first and a second hinge leaf, the second hinge leaf has a first bushing and a second bushing located at a distance therefrom, between which a bushing of the first hinge leaf can be rotated about a mutual hinge axis. An axial tube is rotationally fixed to the bushing of the first hinge leaf and is pivot-supported in the bushings of the second hinge leaf. A torsion spring is disposed in the axial tube and attached to one end of the axial tube. A torque support connects the other end of the torsion spring to the second hinge leaf in a rotationally fixed manner. A damper for the hinge movement is connected to the second hinge leaf and the axial tube. In a cylindrical hollow space of an outer opening, formed by the three bushings (), the damper (), the axial tube () containing the torsion spring (), and the torque support () are inserted successively starting at the second bushing () of the second hinge leaf (), and the torque support () is prevented from rotating and from being axially displaced in the second bushing () by a safety device ().
