The present invention relates to locks for aircraft.

On aircraft, there are a large number of opening of the valves, withholding lock in a predetermined position, for example, in the closed position. We are talking about, for example, hoods, hatches or about the fairings. The lock includes a hook configured to engage with a fixed connection point of the frame. It also contains the control knob hook, usually accessible via the window opening, and the handle is pivotally connected to this door, on the one hand, and with a hook on the other side.

Thus, the outer side of the handle is visible and accessible through the opening of the door. This side usually has a flat shape, which must be in continuation of the front side of the door. However, in the closed position, lock the outside knob may not be the continuation of the front side of the leaf, which is not desirable from the point of view of aerodynamics and aesthetics. This can be avoided by adjusting the position of the connection point of the hook. Indeed, the inclination of the handle in the closed position of the lock depends, in particular, from the position of the hook on the connection point. However, such regulation is time-consuming: really, you need to open the door to gain access to the connection point, then adjust your wrist is on this point of connection, then adjust the length of the hook with the element provided on the hook for this purpose. Indeed, the distance between the connection point and the hinge hook on the handle affects the force that must be applied techniques to handle during lock. After completing these operations, the sash is closed and validates the inclination of the handle. If the slope remains incorrect, these operations are repeated again. Often these operations to be performed more than once, which makes the procedure repeated. In addition, all these operations must be repeated as many times as locks need to be adjusted.

The present invention is to facilitate obtaining the necessary inclination of the handle in the closed position of the lock.

For this purpose, according to the invention, there is a lock for the aircraft, containing the control knob and means for adjusting the height of the handle in the closed position of the lock, and these tools are made with the possibility of control on the handle.

Thus, there is no need to repeatedly open and close the lock during regulation. The correct inclination of the handle to achieve extremely simply and quickly.

Preferably controls configured to control in a closed position of the lock.

Therefore clicks the zoom, already during the regulation to verify the correct position and, if necessary, to immediately cease operations.

Preferably, the castle contains a safety device configured to lock the control lock with the handle and having an adjustable size.

You can provide that funds tilt contained safety device.

Thus, changing the length of the safety device, receive the correct inclination of the handle. Due to this, you can avoid adding in the lock mechanism, intended only to regulate.

In the embodiment, the castle contains the main hook, the safety device containing a safety hook attached to one of the handle or main hook - using tools to adjust the position of the safety hook on this element.

In another embodiment, the castle contains the main hook, the safety device containing the rod and the safety hook, made with the possibility of engagement with the rod, and the rod mounted on one of the handle or main hook - using tools to adjust the position of the rod relative to this element.

Preferably means replenishment connection screw-nut.

Preferably the nut is self-locking.

Due to this, you can avoid accidentally violating the provisions of the regulation means.

Preferably, the castle contains the main hook, and means to adjust the length of the main hook.

Thus, it is possible to adjust the force which must be applied techniques during the lock.

The object of the invention is also the node that contains:

- frame

- fold and

- the lock is arranged to lock the sash in a closed position relative to the frame, while the castle contains the control knob and means for adjusting the height of the handle in the closed position of the lock, with controls configured to control the outside sash.

Preferably controls configured to control in a closed position of the sash.

The object of the invention is also an aircraft that has a locking device in accordance with the present invention or the site in accordance with the present invention.

Other distinctive features and advantages of the invention will be more apparent from the following description of two embodiments presented as a non-restrictive examples, with reference to the accompanying drawings, on which:

Figure 1 shows the aircraft 2, containing nodes and locks in accordance with the present invention. In this case, this aircraft is a machine heavier than air and, in particular, by plane. The aircraft includes a fuselage 4 and two wings 6 with mounted motors 8.

The plane contains hoods, hatches and fairings, each of which forms a node. Each node contains a frame 9 that is fixed relative to the aircraft structure, for example, rigidly attached to the fuselage, and the sash, such as opening the shutter 10. Storiesteen movable relative to the frame 9, for example, there is articulated around an axis. It may take a predetermined position, such as a closed position in which it covers the opening of the frame, separating, thus, outer space and the inner space of the node and preventing access to the interior.

The site has a locking device 12 in accordance with the present invention, intended to hold the sash 10 in the closed position. The castle contains the main hook 14 is elongated, containing at its free end a curved portion, configured to engage with the shank 16 of the 18 points of connection of the frame 9. Lock 12 includes a handle 20 that is used to control the lock and, in particular, the hook-side of the operator. The knob is movable in the hole or aperture 36 of the sash 10. On the one hand, the handle 20 is hinged to the sash 10 around the axis 21 and, on the other hand, the hook 14 around the axis 22. The rod 16 and the axis 21 and 22 parallel to the hinge axis of the door.

The lock shown in the locked position. In this position the hook on the act efforts along the line 24, which passes through the axis of the rod 16 and through the axis 22. In the closed position, the line 24 passes beyond the axis 21. During the closing movement of the axle 21 passes through this line. This configuration provides natural hold and lock in closed position when any effort dei the plans of the castle along the line 24.

The hook 14 is the device 34 regulation of its length, containing, for example, the connection screw and allows you to adapt the lock 12 to the real position of the point 18 of the connection and to regulate, thus, the lever force to be applied techniques to handle during closing of the lock.

The lock further comprises a safety device, ortrigger30. This device comprises, on the one hand, the safety rod 31 and the safety hook 32, in this case, the double hook, made with the possibility of engagement with the rod 31. In this example, this rod is installed on the main hook 14, while the safety hook 32 is mounted on the handle 20. This safety device 30 forms constipation, internal to the lock 12. When the hook 32 is engaged with the rod 31, as shown in the figures, the device 30 prevents the control of the main hook 14 by means of the handle 20. Indeed, the safety hook 32 and the rod maintain a constant distance between the main hook and handle. This additional lock ensures reliable closing of the lock, preventing any accidental rotation of the handle. For lock opening 12 a technician must first disable the safety device to disconnect the latch 32 of the rod 31.

Lock 12 includes a button 38, W is Mirna installed on the handle around its axis 40 and is arranged to move in the hole 42 of the wall. The button 38 has a hook 32. When the technician presses the end button 38, on the opposite side of axis 40 relative to the safety hook 32, this causes the button to turn and allows you to disconnect the hook 32 of the rod 31, which leads to the disabling of the safety device.

Next, with reference to figure 5-8 follows the description of the first variant of execution.

The hook 32 is attached to the button 38. As for the rod, it is rigidly fixed to the hook 14 without regulation. Means are provided for changing the position of the hook relative to the button in the direction perpendicular to the flat outer side 56 of the handle and to the outer side 44 of the sash. In this case, these means include a screw 46 passing through the coaxial holes of the button 38 and the hook 32. The button hole 38 does not contain the thread, but the opening of the hook 32 threaded for engagement with the screw. The screw is engaged with the nut near its free end, such as self-locking nut 48, as shown in Fig.7, or sleeve 49, known as the “EN6092” and shown in Fig. During the rotation of the screw head located on the side 56, a spiral threaded connection between the screw 46 and the hook causes the hook to ascend or descend on the button and changes, thus, the size l of the safety device 30. This region is setting the log file name, shown in figure 4, measured between the axis 40 and the axis of the rod 31.

The second option is shown on figures 9-12. In this embodiment, the safety hook 32 is rigidly secured to the button 38 without regulation. To regulate in this case, the position of the rod 31 relative to the main hook 14. For this purpose, the rod 31 is divided into two parts, fixed on the nut 50 and passing on both sides of the nut, continuing each other, perpendicular to the main axis of the nut. The hook 14 has a casing 54 in a generally cylindrical shape, perpendicular to the General direction of the hook and in the direction of the handle. This casing 54 includes two vertical straight elongated groove 52, which respectively enter part of the rod 31. Thus, these parts together with the nut can be moved by sliding in the channel 54. When a screw 56 which passes through the button hole 38 and the hole of the hook 32, and these two holes do not contain thread, and ultimately engages with the nut 50. The rotation of the screw when subjected to a head of the screw adjacent to the side 56, allows you to change the position of the rod 31 and thus, the size 1 of the safety device.

Thus, in these two versions of the use of the safety device 30 with adjustable size l, which is measured in the direction of the tion, not parallel to the hook 14 and the handle 20. This regulation leads to a change in the overall length of the safety device 30. It can take place when the lock is in the closed position and the shutter is in the closed position, by means of the screw 46 extending on the outer side 56 of the handle, that is externally accessible node. At this point 18 connection after closing the sash is not available.

Changing the size of the safety device leads to a change of the angle between the handle 20 and the hook 14 and hence to the change in the slope or landing of the handle 20 relative to the outer side 44 of the sash. Thus, this slope can be adjusted so that the outer side 56 of the handle was on the same level or in the continuation of the outer side 44 of the leaf.

Point 18 of the connection may be, for example, on the fuselage, wing, nacelle, etc.

It should be noted that the invention eliminates the use of the means of adjusting the position of the point 18 of the connection. We are talking about significant advantage as the system of regulation of these points, which are considerable effort, as a rule, are of great weight.

Of course, in the invention it is possible to make various modifications without going beyond it. You can pin a safety hook on the main hook, and not on the stick is, similarly, the rod 31 can be attached to the handle, not on the main hook.
