Description

TECHNICAL FIELD

[0001] The present invention relates to a door locking assembly for locking a door of an aircraft. The present invention also relates to an aircraft comprising such a door locking assembly. BACKGROUND

[0002] Aircrafts usually have respective aircraft doors enabling crew members and / or passengers to easily access the aircraft. The respective aircraft doors are usually embodied as hinged doors, but other types of doors can also be used depending on the given type of aircraft. For example, in a rotorcraft such as a helicopter, a sliding door can be used to open or close a corresponding hole provided in the rotorcraft. Such a sliding door is usually guided on the rotorcraft via a suitable guide rail from an open position at a predetermined distance along the outer surface of the rotorcraft up to the height of the corresponding hole provided in the rotorcraft, and then via a suitably curved or bent end portion of the guide rail into the hole into a respective closed position.

[0003] Conventional sliding doors usually comprise one or more sliding arm assemblies rigidly mounted to a plate-like support of the sliding door via associated mounting plates by means of suitable fasteners such as screws. The one or more sliding arm assemblies are for example rigidly mounted to a door leaf of the sliding door. Each of the one or more sliding arm assemblies supports one or more roller carriages with associated guide rollers adapted to roll along a given guide rail in operation. The one or more roller carriages, i.e. the associated guide rollers, are adapted to engage the given guide rail in a receptacle provided on or in the given guide rail. An exemplary sliding door of a rotorcraft is described in document EP3825226A1.

[0004] Usually, a given sliding door in a rotorcraft has to be manually moved along the guide rail, for example starting from a corresponding fully open position, and has to be manually locked in the hole of the rotorcraft in a corresponding fully closed position. Furthermore, it can be necessary to lock the given sliding door in the corresponding fully open position in order to prevent the given sliding door from accidentally and unintentionally moving from the corresponding fully open position in the direction of the corresponding fully closed position, since such a movement can result in injuries and damages of for example a respective operator of the given sliding door and / or a passenger of the rotorcraft. For example, it can be necessary to lock the given sliding door in the corresponding fully open position in order to achieve a safe and reliable lifting operation. Therefore, it is necessary to provide a suitable door locking assembly for locking and holding the given sliding door in the corresponding fully open position upon reaching the corresponding fully open position.

[0005] Document EP3571365B1 describes a door locking assembly for locking a door leaf of a sliding door in an aircraft onto a door frame. The locking of the door leaf to the door frame is achieved by engaging a latching element with a latching unit, wherein the latching element is designed as an oblong flat portion with a latching recess, which is engaged by a latching body of the latching unit to be latched in a latched and locked state of the door locking assembly.

[0006] Document EP2872395B1 describes a door locking assembly for locking a sliding door of an aircraft in a fully open position. The door locking assembly comprises a plurality of component parts, including a handle, a cable, a hook, a bracket, etc.

[0007] However, generally door locking assemblies are not only provided to hold a given sliding door in its fully open position in a respective latched and locked state, but also to achieve a simple and ergonomic unlatching and release. Furthermore, such door locking assemblies should be adapted to absorb the respective opening energy generated by a given sliding door upon reaching the fully open position, furthermore, to have no friction wear and no noise generation during operation. Furthermore, such door locking assemblies should provide information about their current state, i.e. whether it is in a locked state or in a released state, and it should be easy and safe to install in a respective rotary-wing aircraft.

[0008] Generally, all these different and separate functions of a door locking assembly are performed by various different component parts, so that conventional door locking assemblies are complex and heavy due to the larger number of component parts. However, due to the complexity of conventional door locking assemblies, they generally require a considerable installation space. Furthermore, due to the larger number of component parts, conventional door locking assemblies are prone to malfunctions, which can lead to accidents, for example, in the flight operation of a respective rotary-wing aircraft. Furthermore, conventional door locking assemblies are generally difficult to lock / unlock by a respective operator, potentially leading to hazardous events. In particular, it is generally not possible to lock / unlock conventional door locking assemblies with one hand and with proper ergonomics. Reference is made to WO2014011130, US2003146643, CN114109195 and EP3922546. SUMMARY

[0009] It is therefore an object of the present invention to provide a new door locking assembly for locking a sliding door of an aircraft and more generally for locking any type of door of any type of vehicle. The new door locking assembly is preferably adapted to lock the door in a fully open position and is capable of improving the reliability and safety of the door in the locked state.

[0010] The above object is solved by a door locking assembly having features according to the present application. More specifically, according to the present application, a door locking assembly for locking a door of an aircraft comprises a locking hook adapted to block a lockable arm of a door of an aircraft in a locked position, a release lever connected to the locking hook for moving the locking hook from a released position to the locked position in response to being actuated by the lockable arm of the door of the aircraft, an operating handle connected at least to the release lever and rotatable for moving the locking hook from the locked position to the released position, and a locking indicator connected to the locking hook for indicating the positioning of the locking hook in one of the locked position and the released position.

[0011] Advantageously, the door locking assembly of the present application forms a lightweight self-locking and latching system with integrated unlocking or release lever, visual indication means and a damping or damping member, and it enables a safe and ergonomic unlocking. More specifically, it has a simple design with a reduced number of constituent parts and enables the creation of a standard equipment part for any type of door. Thus, any type of door can be designed to have a safe locked state in the fully open position and to be unlocked via a simple unlocking operation, which can be performed by the operator with only one hand. The design enables a safe and reliable use as well as an easy maintainability and inspection, and it is particularly advantageous for use in aircrafts with sliding doors that have to be lockable in the fully open position.

[0012] Preferably, the door locking assembly of the present application is designed for locking a locker realized by a lockable arm, which is for example mounted on the door, i.e. attached to the respective door leaf. The lockable arm can for example be provided with a guiding member realizing a fail-safe function. The door locking assembly of the present application can thus for example be mounted to an associated door frame, preferably comprising an integrated lever realized by the locking hook, the release lever, the operating handle and the locking indicator, but without any lever or kinematics being required in a conventional door locking assembly. The locking indicator preferably constitutes a direct visual means, for example a visual indicator integrated on the door locking assembly. More specifically, the locking indicator forms a marking system, which can be clearly seen and unambiguously understood by the operator.

[0013] The door locking assembly of the present application can further comprise an integrated absorption damper forming a damping member, in particular an elastomer damper. Such a damping member can prevent damages and wear due to vibrations, but it can also be adapted to absorb energy. Furthermore, a pre- and ratchet locking system can be integrated into the door locking assembly. For example, the pre- and ratchet locking system can comprise a ratchet recess adapted to ratchet the lockable arm of the door performing a locking movement towards the door locking assembly.

[0014] Moreover, two different configurations are possible. More specifically, the door locking assembly can advantageously be mounted on the associated door frame or, alternatively, on the given door, i.e. the door leaf. Likewise, if the door locking assembly is mounted on the associated door frame, the lockable arm can be mounted to the given door, i.e. the door leaf, or, if the door locking assembly is mounted on the given door, i.e. the door leaf, the lockable arm can be mounted to the associated door frame. In both configurations, the respective required installation space is identical at least within the associated manufacturing tolerances, and the adaptation of the door locking assembly and / or the lockable arm is configuration-independent and, therefore, not necessary.

[0015] In summary, the door locking assembly of the present application is safe and reliable, has a lower complexity due to the reduced number of constituent parts, and is provided with a visual indication device. Due to its lower complexity due to the reduced number of constituent parts, the respective costs and the associated weight can advantageously be reduced. Moreover, it can be used on direct locking devices inside and outside of opening systems such as doors or fairings. In particular, it enables a reduction of the perceived noise during door closing and in flight due to the required rod vibrations or kinematics in conventional door locking assemblies. Moreover, it enables an easy and ergonomic use with only one hand of the operator.

[0016] According to some aspects, the locking hook is rigidly attached to or integrally formed with the release lever.

[0017] According to some aspects, the locking hook and the release lever form a plate-like locking and release element.

[0018] According to some aspects, the plate-like locking and release element is rotatably mounted to the associated housing.

[0019] According to some aspects, the plate-like locking and release element is rotatably mounted to the associated housing via a rotation axis.

[0020] According to some aspects, the locking indicator is rotatably mounted to the associated housing via a rotation axis.

[0021] According to some aspects, the rotation axis is non-rotatably mounted to the associated housing.

[0022] According to some aspects, the locking indicator is connected to the locking hook by means of at least one drive guide pin provided on the plate-like locking and release element.

[0023] According to some aspects, the at least one drive guide pin is movably arranged in an arc-shaped guide groove.

[0024] According to some aspects, the arc-shaped guide groove is formed in the associated housing.

[0025] According to some aspects, the operating handle is rotatably mounted to the associated housing by means of a connection member, in particular a connection shaft.

[0026] According to some aspects, the operating handle is connected to the plate-like locking and releasing element via a clutch unit provided in the associated housing.

[0027] According to some aspects, the associated housing forms a catch recess which is adapted to catch a lockable arm of a door of an aircraft which performs a locking movement towards the associated housing.

[0028] According to some aspects, the door locking assembly further comprises a damping member which is adapted to dampen the locking movement of a lockable arm of a door of an aircraft at the associated housing.

[0029] The invention also provides an aircraft comprising a door equipped with a lockable arm and a door locking assembly for locking the door as described above. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0039] Figure 1 A vehicle 1 is shown, which is exemplarily shown as an aircraft, in particular a rotorcraft, more specifically a helicopter. Thus, for the purpose of simplicity and clarity, the vehicle 1 is in the following referred to as "rotorcraft 1". However, the present invention is not limited to rotorcraft, but is equally applicable to any other vehicle, in particular to a vehicle which is controllable independent of its specific configuration in a flowing medium, such as air or water.

[0040] Illustratively, the rotorcraft 1 comprises a fuselage 1 a and a tail boom 1 b, which exemplarily comprises a tail fin 1 c, a vertical tail fin 1 d and a shroud 1 e for accommodating a suitable counter torque device, such as a tail rotor, which is configured to provide a counter torque during operation in order to balance the rotorcraft 1 in terms of yaw. The tail boom 1 b can further be provided with a horizontal stabilizer, a bumper, etc.

[0041] It should be noted that for the purpose of simplicity and clarity of the drawings, only the fuselage 1 a and the tail boom 1 b are shown in Figure 1 However, other conventional components, such as the main rotor and the landing gear of the rotorcraft 1, are not shown, since they are well known to the skilled person and thus are not part of the present invention and would only unnecessarily impede and complicate the display.

[0042] Illustratively, the fuselage 1 a comprises at least two longitudinal side walls, a port side wall 1 f and a starboard side wall 1 g. The fuselage 1 a preferably defines at least a cockpit, a passenger cabin and / or a cargo cabin. However, for the purpose of simplicity and clarity of the description, such cockpit, passenger cabin and cargo cabin are not explained in more detail.

[0043] For example, at least the port sidewall 1f is provided with a sliding element region 2, in which a sliding element device having at least one upper guide rail device 2a and at least one lower guide rail device 2b can be provided. Figure 2 (3) Illustratively, the upper guide rail device 2a and the lower guide rail device 2b are attached to the fuselage 1a.

[0044] More specifically, the upper guide rail device 2a and the lower guide rail device 2b are preferably adapted to slidably receive sliding elements, particularly sliding doors. Figure 2 4) or a sliding window, sliding door or sliding window is adapted to open or close the hole 1h provided in the sliding element area 2 of the port sidewall 1f, preferably in a sealed manner. For example, the hole 1h is equipped with a frame 2c.

[0045] According to one aspect of the invention, the starboard sidewall 1g also has a sliding element region 2, in which at least one upper guide rail device 2a and at least one lower guide rail device 2b are attached to the fuselage 1a, and a hole 1h for receiving the sliding element is provided in the sliding element region 2. More specifically, the starboard sidewall 1g preferably has a sliding element device, which is preferably embodied in a manner similar to... Figure 2 3. Sliding element device.

[0046] Figure 2 The sliding element device 3 is shown, which is illustratively adapted to... Figure 1 Installed at 2 locations in the sliding element area Figure 1 The sliding element device 3 is mounted on the port sidewall 1f of the fuselage 1a of the rotorcraft 1. Illustratively, the sliding element device 3 is mounted on the frame 2c of the fuselage 1a, and the frame 2c is located in the sliding element area 2.

[0047] The sliding element device 3 preferably includes at least one sliding element 4, particularly a sliding door or sliding window, and Figure 1 The upper guide rail device 2a and the lower guide rail device 2b preferably include associated sliding element guide rails 7, which are preferentially attached to the upper guide rail device 2a by means of suitable fasteners (e.g., screws, bolts, rivets, etc.). Figure 1 The port sidewall 1f of the rotorcraft 1. For the sake of brevity and simplicity, the associated sliding element rail 7 is referred to as "rail 7" below.

[0048] For simplicity and clarity, the sliding element 4 is illustratively represented as a sliding door including at least a door leaf 4a and is therefore also referred to as "sliding door 4" below. Thus, frame 2c defines the sliding door frame.

[0049] The sliding door 4 is preferably slidably supported by a guide rail 7, allowing the sliding door 4 to slide along the guide rail 7 during operation. More specifically, the sliding door 4 is preferably slidable along the guide rail 7 at least by means of an opening sliding movement in the opening direction from a fully closed position to a fully open position. The fully open position is... Figure 2 As shown in the example.

[0050] In the fully open position, the sliding door 4 is preferably locked by means of an associated door locking assembly 6. The door locking assembly 6 is illustratively disposed in a door locking area 5. For example, the door locking area 5 is located at the upper guide rail assembly 2a, near the upper edge 4b ​​of the door leaf 4a.

[0051] Figure 3 It shows Figure 2 The door locking assembly 6, which is illustratively rigidly mounted to Figure 1 and Figure 2 On the body 1a. More specifically, the door locking assembly 6 is rigidly mounted near the upper guide rail 7a of the guide rail 7, the upper guide rail 7a being Figure 2 It is part of the upper guide rail device 2a.

[0052] exist Figure 3 In the middle, the door locking component 6 will Figure 2 The sliding door 4 is locked in its fully open position. To lock the sliding door 4 in its fully open position, the sliding door 4 is provided with a lockable arm 4e. Illustratively, the lockable arm 4e is rigidly mounted to the sliding door 4 via a locking lug member 4c. For example, the locking lug member 4c can be rigidly mounted to the door leaf 4a, for example at the upper edge 4b ​​of the door leaf 4a, or rigidly mounted to a roller bracket provided at the upper edge 4b. Furthermore, the locking lug member 4c can be provided with a guide member 4d for implementing a fail-safe function of the sliding door 4.

[0053] Illustratively, the lockable arm 4e is locked by the door locking assembly 6. The door locking assembly 6 includes a locking hook 6a adapted to block the lockable arm 4e of the sliding door 4 in the illustrated locked position. For example, the locking hook 6a extends into a corresponding lug formed by the locking lug member 4c in the illustrated locked position.

[0054] In addition, the door locking assembly 6 includes a release lever connected to the locking hook 6a. Figures 4 to 6 (6i), used to release the locking hook 6a from the lockable arm 4e in response to actuation. Figure 4 and Figure 5 The release position shown has been moved to the locked position. Release lever ( Figures 4 to 6 6i) is connected to the operating handle 6d, which is rotatable to move the locking hook 6a from the locked position to the operating handle 6d. Figure 4 and Figure 5The release position is shown. The operating handle 6d may include a grip plate 6n that enables easy and comfortable operation of the operating handle 6d.

[0055] Furthermore, the locking hook 6a is connected to the locking indicator 6b, which is configured to indicate the positioning of the locking hook 6a in either the locked or released position. Figure 3 In the middle, the locking indicator 6b illustratively indicates the positioning of the locking hook 6a in the locked position.

[0056] Preferably, the locking hook 6a is rotatably mounted to the associated housing 6g via a rotating shaft 6c. Similarly, the locking indicator 6b is preferably rotatably mounted to the associated housing 6g via a rotating shaft 6c. The rotating shaft 6c is preferably non-rotatably mounted to the associated housing 6g. The associated housing 6g can be rigidly attached to the fuselage 1a.

[0057] Furthermore, the operating handle 6d is preferably rotatably mounted to the associated housing 6g by means of a connecting member 6e, particularly a connecting shaft. More specifically, the operating handle 6d can be connected to the release lever via a clutch unit 6f disposed in the associated housing 6g. Figures 4 to 6 (6i in the original text). Suitable clutch units that can be used to implement clutch unit 6f are well known to those skilled in the art and are therefore not part of this invention. Therefore, for the sake of brevity and conciseness, a detailed description of clutch unit 6f is omitted.

[0058] Illustratively, the associated housing 6g forms a locking notch 6h, which is adapted to lock the lockable arm 4e when it performs a locking movement toward the associated housing 6g. The locking notch 6h is preferably at least approximately V-shaped to ensure that the lockable arm 4e reliably enters the locking notch 6h during the locking movement.

[0059] Figure 4 It shows Figure 3 A sliding door 4 having a lockable arm 4e and a locking lug member 4c, and Figure 3 Door locking component 6, door locking component 6 as Figure 3 The upper guide rail 7a, illustratively located near guide rail 7, is rigidly mounted to the fuselage 1a. As described above... Figure 3 As described above, the door locking assembly 6 illustratively includes a locking hook 6a, a locking indicator 6b, a rotating shaft 6c, an operating handle 6d with a gripping plate 6n, a connecting member 6e, an associated housing 6g, and a locking recess 6h.

[0060] The door locking assembly 6 also includes a release lever 6i. Preferably, the release lever 6i is rigidly attached to or integrally formed with the locking hook 6a.

[0061] Furthermore, the door locking assembly 6 may include a damping member 6j, illustratively received in a locking recess 6h formed in the associated housing 6g. The damping member 6j may be embodied as an absorber, particularly an elastomeric absorber. The damping member 6j may be configured to prevent damage and wear due to vibration, but it may also be adapted to absorb energy, as described below. Figure 5 The description.

[0062] More specifically, Figure 4 An illustrative unlocking process performed by means of door locking assembly 6 is shown. The illustrative unlocking process implies the movement of different components in different directions of movement, indicated by arrow 8.

[0063] The illustrative unlocking process begins with operating the 6d handle from... Figure 3 The initial standby position shown is in Figure 4 The rotation in the rotation direction 8a, as shown, causes the operating handle 6d to rotate about the connecting member 6e. For example, the operator pushes the grip plate 6n of the operating handle 6d in the rotation direction 8a.

[0064] By rotating the handle 6d, the locking hook 6a moves around the rotation axis 6c in the rotation direction 8a. Figure 3 The locking position shown is rotated to the release position shown. Simultaneously, the release lever 6i rotates about the rotation axis 6c in the rotation direction 8a, and pushes the lockable arm 4e out of the locking recess 6h in the ejection direction 8b. For example, the locking hook 6a and the release lever 6i rotate within a guide groove 6m embodied in the associated housing 6g.

[0065] Rotation of the locking hook 6a and the release lever 6i about the rotation axis 6c in the rotation direction 8a causes rotation of the locking indicator 6b about the rotation axis 6c in the rotation direction 8a. This rotation is caused by a drive guide pin 6k, which is attached to or integrally formed with the locking hook 6a and / or the release lever 6i, and is movably disposed in a guide groove 6l such that the drive guide pin 6k carries the locking indicator 6b. The guide groove 6l is illustratively arcuate and is formed in the associated housing 6g.

[0066] At the end of the illustrative unlocking process, the locking indicator 6b indicates the locking hook 6a in the released position, and thus indicates that the sliding door 4 has been unlocked. Furthermore, the operator preferably releases the grip plate 6n of the operating handle 6d at the end of the illustrative unlocking process. This causes the operating handle 6d to rotate in the opposite direction to the rotation direction 8a, causing the operating handle 6d to move from its indicated end position back to its original position. Figure 3 The initial standby position is shown. For example, the operating handle 6d can be biased by a suitable spring element.

[0067] Figure 5 It shows Figure 4 A sliding door 4 having a lockable arm 4e and a locking lug member 4c, and Figure 3 and Figure 4 Door locking component 6, door locking component 6 as Figure 4 The upper guide rail 7a, illustratively located near guide rail 7, is rigidly mounted to the fuselage 1a. As described above... Figure 4 As described above, the door locking assembly 6 illustratively includes a locking hook 6a, a locking indicator 6b, a rotating shaft 6c, an operating handle 6d with a gripping plate 6n, a connecting member 6e, an associated housing 6g with guide grooves 6l and 6m, a locking notch 6h, a release lever 6i, and a damping member 6j.

[0068] More specifically, Figure 5 An illustrative locking process performed by means of door locking assembly 6 is shown. The illustrative locking process implies the movement of different components in different directions of movement, indicated by arrow 8.

[0069] The illustrative locking process begins with the movement of the sliding door 4 toward the door locking assembly 6 in the locking movement direction 8c, i.e., illustratively, in the locking movement direction 8c. This causes the lockable arm 4e to undergo a locking movement in the locking movement direction 8c.

[0070] Upon reaching the door locking assembly 6, the lockable arm 4e is engaged in the locking recess 6h, with the lockable arm 4e abutting against the release lever 6i. Further movement of the lockable arm 4e in the locking movement direction 8c causes rotation of the release lever 6i, and thus causes the locking hook 6a to move about the rotation axis 6c in the rotation direction 8d from the illustrated release position to... Figure 3 The rotation to the locked position is shown. In other words, in response to the release lever 6i being actuated by the lockable arm 4e, the locking hook 6a rotates to the locked position.

[0071] The rotation of the locking hook 6a and the release lever 6i about the rotation axis 6c in the rotation direction 8d causes the locking indicator 6b to rotate about the rotation axis 6c in the rotation direction 8d. This rotation is caused by the drive guide pin 6k carrying the locking indicator 6b.

[0072] At the end of its locking movement in the locking direction 8c, the lockable arm 4e abuts against the damping member 6j. The damping member 6j is preferably adapted to dampen the locking movement of the lockable arm 4e at the associated housing 6g.

[0073] Therefore, at the end of the illustrative locking process, the locking indicator 6b indicates that the locking hook 6a is in accordance with... Figure 3 The locking position is determined, and thus indicates that sliding door 4 is locked.

[0074] It should be noted that the entire illustrative locking process is performed solely by sliding the sliding door 4 along the guide rail 7 to its fully open position. This activates the door locking assembly 6 and locks the sliding door 4 in its fully open position without requiring manual operation by the operator. Therefore, the operating handle 6d remains in place throughout the entire illustrative locking process. Figure 4 The initial standby position is shown.

[0075] Figure 6 It shows Figure 4 A sliding door 4 having a lockable arm 4e and a locking lug member 4c, and Figures 3 to 5 Door locking component 6, door locking component 6 as Figure 4 The upper guide rail 7a, illustratively located near guide rail 7, is rigidly mounted to the fuselage 1a. As described above... Figure 4 As described above, the door locking assembly 6 illustratively includes a locking hook 6a, a locking indicator 6b, a rotating shaft 6c, an operating handle 6d with a gripping plate 6n, a connecting member 6e, an associated housing 6g with guide grooves 6l and 6m, a locking notch 6h, a release lever 6i, and a damping member 6j.

[0076] Preferably, the locking hook 6a and the release lever 6i form a plate-shaped locking and releasing element 6o. More specifically, the locking hook 6a is rigidly attached to or preferably integrally formed with the release lever 6i to form a plate-shaped locking and releasing element 6o.

[0077] The plate-shaped locking and releasing element 6o is preferably rotatably mounted to the associated housing 6g. More specifically, the plate-shaped locking and releasing element 6o is rotatably mounted to the associated housing 6g via a rotation shaft 6c in a guide groove 6m. Thus, as described above, both the locking hook 6a and the releasing lever 6i can rotate about the rotation shaft 6c.

[0078] Preferably, the plate-shaped locking and releasing element 6o is provided with a drive guide pin 6k, which connects the plate-shaped locking and releasing element 6o to the locking indicator 6b, and thus to the locking hook 6a, as described above. Furthermore, the plate-shaped locking and releasing element 6o is preferably connected to the operating handle 6d via a clutch unit 6f disposed in the associated housing 6g. The clutch unit 6f may include a connecting member 6e.

[0079] It should be noted that modifications to the above embodiments are within the scope of ordinary knowledge of those skilled in the art and are therefore also considered part of this invention. For example, in Figures 3 to 6In the embodiment shown, the sliding door 4 is provided with the lockable arm 4e and the door locking assembly 6 is rigidly mounted to the fuselage la. Alternatively, the sliding door 4 can be provided with the door locking assembly 6 and the lockable arm 4e can be rigidly mounted to the fuselage la, etc.
