Embodiment Construction

[0025] figure 1 and figure 2 A lock 100 according to an embodiment of the invention is shown in so-called closed and locked positions and in closed and unlocked positions. In the following description, the "closed position" of the lock 100 refers to both the closed and locked positions as well as the closed and unlocked positions. The lock 100 is intended, for example, to be fixed to a swing or sliding door of a helicopter. In the example, the lock 100 is considered movable relative to the structure of the helicopter.

[0026] The lock 100 comprises two substantially identical walls 101 in planar form, which are spaced apart according to a first pivot link axis 102 and a second pivot link axis 103 . The first and second axes ( 102 , 103 ) are substantially perpendicular to the plane of the wall 101 . exist Figure 1 to Figure 6 In , only one wall 101 is visible since the lock 100 is shown in longitudinal section or side view. The walls 101 comprise, on their periphery, ...

Abstract

The invention relates to a lock (100) comprising two substantially planar walls (101) carrying a first pivotal connection (102) and a second pivotal connection (103), said first and second The two axes are substantially perpendicular to the plane; the hook (108) can pivot around the first axis, and the hook includes a hook (109) capable of hooking a steel wire; the pawl (111) can pivot around the first axis. The second shaft pivots, the pawl comprises a tooth (112) capable of engaging with at least one notch (113, 114) formed in the hook when the lock is in the so-called closed position a control lever (115), pivotable around said second axis, said lever comprising a member (116) for driving the rotation of said pawl around said second axis, a control lever comprising means for tightly closing said lock components of (118, 119).

Description

technical field [0001] The invention relates to a lock. More specifically, the present invention relates to a lock for a door of eg a vehicle, an aircraft. Background technique [0002] Locks known in the prior art comprise a planar support carrying a first pivot link shaft about which a hook pivots, said hook comprising a hook that rotates about a socket; and a pawl and a rotatable A second pivot link shaft about which a control lever for driving a pawl pivots, said pawl comprising a tooth which engages with a notch formed on the hook when the lock is in the so-called closed position. A lock of this type is described, for example, in document US 2004 / 0135378. [0003] However, with such a lock, in an abnormal event such as the presence of significant vibrations, it can happen that the teeth of the pawl unintentionally disengage from the cutouts formed in the hook, thereby releasing the socket by the hook and thus the lock opening. This situation is especially dangerous i...
