  • the main function of such a lock is to securely lock and unlock the lid or luggage tub or chute of a luggage box in all flight conditions, including emergency landing conditions.
  • the drive means within the lock is connected by a mechanical link to a control knob or handle mounted on the deck so as to be operable from outside the luggage box.
  • the operation of the knob or handle leads in the known lock to a rotational movement of the mechanical link, through which the lock is unlocked.
  • the lock is designed so that inadvertent opening in the loaded or unloaded state of the luggage box. is prevented.
  • the latch of the lock has a fail-safe function. This purpose serves a double lock.
  • This double locking is done in the known lock on the one hand by a locking pin, which is detected by a locking hook, and on the other by a locking pin which protrudes from the case when the lid of the luggage box is open, but at the closing of the lid of the luggage box by the locking bolt means is pressed into the housing of the trap.

  • the striker pushes the locking pin, which moves past it, into the housing of the latch.
  • the known lock is not applicable at all.
  • the locking bolt device is adjustable in two axes.
  • the locking pin also serves as a stop for an end stop. This has the disadvantage that with each adjustment of the locking bolt device and the stop of Endstops adjusted and must be readjusted.
  • the opening of the Lock by pulling the operating handle. But since there is no transmission between the operating handle and the shaft, a higher operating force is required.
  • a lock for housing, tool boxes or the like is known.
  • This lock has two locking pins on a cover and two pivotable about a pivot axis locking hook, which are pivoted together by a manually operable drive means.
  • a luggage box in an aircraft must have two locks, which can be operated by a common operating button. The famous castle is not suitable for this. It can be actuated by two push buttons located to the left and right of the lock. The push buttons are connected to the locking hooks by a common rigid actuator, by the displacement of the two locking hooks are pivoted together.
  • Such a lock should not be used in the luggage box of an aircraft, because the locking hooks are not individually operable. If a locking hook should be blocked, the other locking hook would be blocked by him.

  • the castle includes two each one
  • Pivot axis pivotable locking hooks which are pivoted together by means of a drive device in the form of a rack. Also, this known lock would not be used in a luggage box of an aircraft, because both locking hooks, at least in the opening direction, are only jointly pivoted. If a locking hook would be blocked in the closed state, the other locking hook could not be opened by means of the drive device.
  • the object of the invention is to provide a lock of the type mentioned in such a way that it avoids the aforementioned disadvantages and in particular can be used in a luggage box, even if the operating knob or - handle is not on the axis of the case.

  • the use of a light control cable brings a weight advantage. Installation is uncomplicated, because control cables can be mounted much cheaper than CFK shafts and levers. In addition to the lower weight and lower assembly costs even lower component costs are added.
  • the main advantage of the lock according to the invention is that the latch and the operating button or handle need not be mounted on a common axle.
  • the fail-safe function is ensured in that the trap has two locking hooks and that each locking hook engages with a locking pin, so that if one of the locking pins or locking hook should fail, the other locking pin and the other locking hook will take up the entire load can.
  • the lock can also be securely locked when only one locking hook is able to its associated locking pin to capture.
  • the linear pulling movement which is generated with the actuating button, is converted into a rotational movement, which in turn translates into a translatory motion. see movement of the rack and the sliding member has the consequence, which take the two locking hooks with them and pivot about the pivot points.
  • the operation by a cable results in a simple, trouble-free, low-weight operation for the gear and makes the previously used in known luggage boxes waves superfluous.
  • the two locks and the pivoting handle of a luggage box no longer need to be mounted on an axle.
  • the locking hooks with the rack or the sliding member are each connected by a toggle which is hinged to the locking hook next to the pivot axis so that the locking position only by tensile force on the pivot point of the toggle lever on the locking hook again can be opened.
  • This makes it easy to use the fail-safe (double locking) and positive locking functions required in aviation technology.
  • the latter is achieved according to the invention in that the toggle levers can each be brought into an end-position blocking position in which they are mechanically locked and thus automatically prevent the lock from cracking due to overload or vibration.

In this case, however, the luggage can be removed and ensured that the lock closes safely with only one locking hook. If the locking tongs associated with the rack are clamped closed and can not be unlocked by manual operation using the emergency lever, the lock remains locked and must be serviced. This means that the luggage can only be removed after the repair.

Abstract

L'invention concerne une serrure pour un coffre à bagages monté en hauteur dans la cabine d'un avion, comprenant un boîtier fixe et un couvercle pivotant autour d'un axe de rotation. La serrure comprend un agencement de goujons de fermeture pouvant être placé sur le boîtier, portant deux goujons de fermeture (32, 32b) parallèles, un loquet (20) pouvant être placé sur le couvercle avec deux crochets de fermeture (55, 55b) pouvant pivoter chacun autour d'un axe de pivotement (22, 22b) pour saisir les goujons de fermeture (32, 32b) afin de verrouiller la serrure (10) et un mécanisme d'entraînement (60) pouvant être actionné manuellement pour écarter ensemble les crochets de fermeture (51, 51b) des goujons de fermeture (32, 32b) afin de déverrouiller la serrure (10). Le mécanisme d'entraînement (60) comprend une crémaillère (62) et un organe coulissant (64) qui peut se déplacer linéairement contre la pression d'un élément à ressort (70). Les crochets de fermeture (51, 51b) sont chacun reliés à la crémaillère (62) ou à l'organe coulissant (64) par un levier à genouillère (74, 74b) qui est articulé sur le crochet de fermeture (51, 51b) près de son axe de pivotement (22, 22b), si bien que le verrouillage n'autorise l'ouverture que par l'application d'une force de traction au niveau du point d'articulation du levier à genouillère (74, 74b) sur le crochet de fermeture (51, 51b). Cela permet de réaliser simplement les fonctions de sécurité intrinsèque et de verrouillage positif exigées dans l'aéronautique, ce dernier étant réalisé du fait que les leviers à genouillère (74, 74b) peuvent être amenés chacun dans une position finale de verrouillage dans laquelle ils sont verrouillés mécaniquement et empêchent ainsi eux-mêmes une ouverture de la serrure sous l'effet d'une surcharge ou de vibrations.
