Description

[0001] Storage compartment

[0002] The invention relates to a storage compartment, preferably for use in an aircraft, comprising: a storage space, a storage compartment flap, a flap drive, in particular a servomotor, with which the storage compartment flap can be moved between a closed position closing a loading opening of the storage space and an open position releasing the loading opening, a transmission with a drive element, in particular with a drive gear connected to the flap drive, and with an output element, in particular with an output gear connected to the storage compartment flap.

[0003] The general state of the art is known from DE 10 2012 005 917 Al , US 2006 / 0132007 Al and DE 103 43 408 Al .

[0004] Furthermore, DE 20 2010 016 982 Ul, for example, discloses a motion device that can move a flap from an open position to a closed position. The motion device has an actuator connected via a gear drive to an actuator coupled to the flap. A coupling device is effective between the actuator and the actuator. The coupling device has a freewheel for freely moving the actuator to the open or closed position. This allows the flap to be opened or closed both with the actuator and manually. With this state of the art, it should therefore not be necessary to impose short drive cycles on the actuator. This should increase the service life of the actuator.Should the opening or closing movement of the movable furniture part, driven by the actuator, be too slow for the user, he can disengage manually and move the movable furniture part into the opening and closing position by hand.

[0005] In many applications, especially safety-critical ones such as in aircraft, the flap drive must also be protected from unwanted torque. However, the storage compartment flap must reliably remain in its respective end position until the opening or closing process is carried out by the flap drive. For example, it may be necessary to keep the storage compartment flap closed even when subjected to impacts from the cargo, without transmitting torque to the flap drive.

[0006] Against this background, the object of the present invention is to alleviate or eliminate at least some disadvantages of the prior art. The invention preferably aims to create a storage compartment of the type mentioned above in which the flap drive is protected and the storage compartment flap is reliably held in its respective end position.

[0007] This problem is solved by a storage compartment according to claim 1. Preferred embodiments are specified in the dependent claims.

[0008] According to the invention, the transmission has a blocking device, wherein the blocking device blocks the rotation of the storage compartment flap in the direction of the open position in the closed position and / or blocks the rotation of the flap in the direction of the closed position in the open position of the storage compartment flap.

[0009] To reliably prevent the storage compartment door from opening or closing unintentionally, the gearbox incorporates a locking device. When the locking device is engaged, the transmission of torque from the storage compartment door to the door drive, for example, due to impacts during flight, is at least partially, and preferably substantially completely, prevented. In a first embodiment, the locking device blocks the rotation of the storage compartment door towards the open position when the door is in the closed position. In a second embodiment, the locking device blocks the rotation of the storage compartment door towards the closed position when the door is in the open position.Preferably, the blocking device prevents the storage compartment flap from rotating towards the open position when it is in the closed position, and also prevents the storage compartment flap from rotating towards the closed position when it is in the open position. In the blocked closed position, any torque acting on the storage compartment flap in the direction of the open position is not transmitted to the flap drive via the gearbox, but is absorbed by the blocking device. For example, this torque can be diverted to the bearing of the drive element, preferably the drive gear. Similarly, in the blocked open position, any torque acting on the storage compartment flap in the direction of the closed position is not transmitted to the flap drive via the gearbox, but is absorbed by the blocking device.This torque is also preferably transferred to the bearing of the drive element, preferably the drive gear. Therefore, in the blocked closed or open position, the flap drive does not have to work against a torque acting in the direction of the open or closed position to keep the storage compartment flap closed or open.

[0010] In use, for example in an aircraft, the loading opening of the storage compartment is secured by the storage compartment door. The storage compartment comprises the storage space, which in a preferred embodiment is essentially cuboid in shape. Preferably, the storage space is only accessible via the loading opening, which is closed by the storage compartment door.

[0011] In a preferred embodiment, the storage compartment has a floor, preferably substantially flat, on which the cargo, preferably loose, i.e., without its own fastening means, can be placed. Furthermore, the storage space can have an upper wall to define its top edge and / or two side walls to define its sides and / or a rear wall to define its rear edge opposite the loading opening.

[0012] In a preferred embodiment, the storage compartment has a length, i.e., for example in an aircraft, an extension in the longitudinal direction of the aircraft fuselage, of 200 millimeters (mm) to 600 mm and / or a width of 150 mm to 300 mm and / or a height of 150 mm to 300 mm.

[0013] In a preferred embodiment, the storage compartment has a first pivot axis about which the storage compartment flap can be pivoted between the closed and open positions.

[0014] In the closed position, the storage compartment door closes the loading opening leading into the cargo space, preferably substantially completely. For loading and unloading the cargo space, the loading opening is released by pivoting the storage compartment door from the closed to the open position. Preferably, the first pivot axis is stationary with respect to the pivoting motion. Preferably, the first pivot axis is connected to a structural component, preferably of an aircraft. The first pivot axis is preferably designed as a single hinge. With respect to a substantially horizontal arrangement of the aircraft, the first pivot axis preferably extends substantially in a horizontal plane, in particular substantially perpendicular to the longitudinal axis of the aircraft, for example, an aircraft fuselage.In a horizontally oriented aircraft, the storage compartment door is preferably arranged substantially vertically in the closed position and / or substantially horizontally in the open position. The first pivot axis can be located above the storage compartment, so that the storage compartment door can be pivoted upwards from the closed to the open position.

[0015] The flap drive is preferably designed as a single drive unit. The flap drive is preferably an electric motor, in particular a servo motor, for pivoting the storage compartment flap about the first pivot axis. Thus, the flap drive is designed as a pivot drive. By controlling the pivot drive, the storage compartment flap is opened or closed. The pivot drive is preferably configured to apply a torque to the storage compartment flap for pivoting about the first pivot axis.

[0016] For effective torque transmission, the swivel drive is connected to the storage compartment flap via the gearbox. The gearbox converts the drive speed and torque of the drive element coupled to the flap drive into the output speed and torque of the output element, which causes the storage compartment flap to swivel.

[0017] In order to transmit the torque from the pivot drive to the storage compartment flap, the transmission in a preferred embodiment has a drive gear coupled to the pivot drive and an output gear coupled to the storage compartment flap.

[0018] To limit the torque transmission to a portion of the revolution, in a preferred embodiment, the drive gear has drive teeth along a first circumferential section, while the drive gear may be free of drive teeth along a second circumferential section. Preferably, the output gear has output teeth along a first circumferential section. It is further preferred that the output gear be free of output teeth along a second circumferential section. Thus, the drive teeth can extend only over a portion of the circumference of the drive gear, for example, less than three-quarters of the circumference. Similarly, the output teeth can extend only over a portion of the circumference of the output gear, for example, less than three-quarters of the circumference.

[0019] In a preferred embodiment, the blocking device is designed to block the rotation of the output gear in the closed and / or open position of the storage compartment flap. For this purpose, the blocking device can be switched from a release position to a blocking position. In the blocking position, the blocking device blocks the rotation of the output gear when a torque is applied to the storage compartment flap that, in the release position of the blocking device, would cause the rotation of the output gear or introduce a torque into the rotary actuator, which is preferably designed as a servo motor.

[0020] In a preferred embodiment, the locking device is designed to release the rotation of the output element, preferably the output gear, in the closed or open position of the storage compartment flap by rotating the drive element, preferably the drive gear, through a release angle. This allows the output element, preferably the output gear, to rotate beyond the release angle by rotating the drive element, preferably the drive gear, in order to move the storage compartment flap from the closed to the open position or from the open to the closed position. Thus, the locking of the output element, preferably the output gear, can be released by rotating the drive element, preferably the drive gear, via the rotary actuator through the predetermined release angle, which is, for example, from 10° to 50°, preferably substantially 30°.This allows for a particularly reliable and weight-saving design. When moving the storage compartment flap from the closed to the open position, the drive element, preferably the drive gear, is first rotated by the release angle, thereby moving the locking device from the locked to the released position. By rotating the drive element, preferably the drive gear, in the same direction of rotation beyond the release angle, the rotational movement of the drive element, preferably the drive gear, is transferred to the driven element, preferably the driven gear, thus initiating the pivoting of the storage compartment flap. When moving the storage compartment flap from the open to the closed position, this process is carried out in reverse. Unlike the prior art, preferably no separate, i.e.,A latching mechanism, independent of the movement of the drive gear, is provided to block or release the closed or open position of the storage compartment flap.

[0021] Advantageously, the gearbox can handle the locking and unlocking of the storage compartment door. A particularly beneficial feature is that the locking mechanism in the closed or transport position is maintained even during a power outage.

[0022] In order to accomplish the torque transmission after the blockage is released, a preferred embodiment provides that the drive teeth of the drive gear mesh with the output teeth of the output gear in the released state of the output gear.

[0023] In order to enable and release the blockage by rotating the drive element, preferably the drive gear, the blocking device in a preferred embodiment comprises a first engagement element, in particular a first circular arc element, coupled to the drive element, preferably the drive gear, and a second engagement element, in particular a second circular arc element, coupled to the output element, preferably the output gear. In the blocked state of the output element, preferably the output gear, the first engagement element engages with the second engagement element in such a way that the rotation of the output element, preferably the output gear, is blocked.If the storage compartment flap is subjected to a torque acting in the direction of the open position while in the closed position, the first and second engagement elements block each other, preventing the torque from being converted into pivoting the storage compartment flap and from being transmitted to the pivoting drive. One of the first and second circular arc elements is preferably convex, while the other can be correspondingly concave. This allows the first and second circular arc elements to interlock with essentially perfect precision. Preferably, the first and second circular arc elements are free of serrations, i.e., they have smooth circular arc contact surfaces.

[0024] To synchronize the drive and output gears, in a preferred embodiment, the drive gear is coupled to a drive element. This drive element comprises at least one first drive element, which, in the released state of the output gear, engages a first drive part coupled to the output gear. This allows the drive teeth to be precisely threaded into the output teeth to cause the storage compartment flap to pivot. Preferably, a second drive element is coupled to the drive gear and a second drive part to the output gear. Depending on the direction of movement, i.e., from the closed to the open position or vice versa, one of the first and second drive elements is brought into contact with one of the first and second drive parts before the drive and output gears mesh.Depending on the design, the first and / or the second drive element and / or the first and / or the second drive part can each be designed as a drive projection.

[0025] In a preferred embodiment, the transmission is designed to pass through the following states sequentially during the transition from the blocked closed position to the blocked open position:

[0026] 1) In a locked closed position of the storage compartment door, the locking device is arranged in the locking position. If an object (i.e., not the door drive), for example, shifting cargo, applies a torque to the storage compartment door acting in the direction of the open position, the locking device, in the locking position, prevents the rotary element of the door drive, designed for opening the storage compartment door (e.g., a rotary shaft), from being subjected to this torque. Thus, rotation of the rotary element is prevented without the door drive having to exert a holding torque. Advantageously, the torque is not introduced into the door drive but is captured by the locking device in the locking position.

[0027] 2) By rotating the drive element, preferably the drive gear, by a release angle starting from the blocked closed position with the output element, preferably output gear, stationary, the storage compartment flap is brought into an unlocked closed position in which the blocking device is arranged in a release position;

[0028] 3) By further rotation of the drive element, preferably the drive gear, starting from the unlocked closed position, the drive element, preferably the drive gear, is coupled to the output element, preferably the output gear, in such a way that the storage compartment flap is pivoted from the closed to an unlocked open position by transferring the torque from the drive element to the output element, preferably from the drive gear to the output gear;

[0029] 4) By further rotation of the drive element, preferably the drive gear, starting from the unlocked open position by a locking angle, which preferably corresponds to the release angle, the storage compartment flap is brought into the blocked open position, in which the blocking device is arranged in the blocking position, so that a torque applied to the storage compartment flap, acting in the direction of the closing position, is not introduced into the flap drive.

[0030] Accordingly, the gearbox is designed to pass through these states in reverse order when transitioning from the blocked open position to the blocked closed position.

[0031] In a preferred embodiment, the transmission has a gear ratio greater than 1, preferably from 1 to 5, preferably from 2 to 4, for example substantially 3, i.e. a reduction ratio.

[0032] In a preferred embodiment, the gearbox has a first end stop to limit the rotation of the drive gear when the closed position is reached and / or a second end stop to limit the rotation of the drive gear when the open position is reached.

[0033] If the storage compartment door is locked in the closed position by the locking device, the locking device prevents the door from pivoting towards the open position when a torque is applied to the door in the direction of the open position, without the door drive having to absorb the torque. If the storage compartment door is locked in the open position by the locking device, the locking device prevents the door from pivoting towards the closed position when a torque is applied to the door in the direction of the closed position, without the door drive having to absorb the torque.

[0034] The invention is further explained below with reference to a preferred embodiment.

[0035] Fig. 1 shows a view of a storage compartment according to the invention in a closed position of a storage compartment flap.

[0036] Fig. 2 shows a view of the storage compartment of Fig. 1 in an open position of the storage compartment flap.

[0037] Figs. 3A to 3E show different views of the storage compartment door.

[0038] Figs. 4A to 4E show various diagrammatic views of a gear unit of the storage compartment according to Figs. 1 to 3, viewed from one side.

[0039] Figs. 5A to 5E show various diagrammatic views of the gear mechanism of the storage compartment according to Figs. 1 to 3, seen from the other side.

[0040] Figures 6A to 6E show various side views of the gearbox according to Figures 1 to 3, viewed from one side. Figures 7A to 7E show various side views of the gearbox according to Figures 1 to 3, viewed from the other side.

[0041] Figures 1 and 2 show a part of an aircraft 1, which is, for example, an airplane. The aircraft 1 has a storage compartment 2 with a storage space 3 in which cargo 4 can be stowed. The storage compartment 2 has an upper wall 5 to define the top of the storage space 3, two side walls to define the sides of the storage space, a rear wall 6 to define the back of the storage space 3, and a bottom 7. Furthermore, the storage compartment has a loading opening 8 for loading and unloading the storage space 3. A storage compartment door 9 is provided at the loading opening 8, which is mounted on a structural component 1A of the aircraft (shown only symbolically). The storage compartment door 9 can be moved between a closed position, as shown in Figure 1, and an open position, as shown in Figure 2.In the closed position, the storage compartment flap 9 preferably closes the loading opening 8 of the storage compartment 3 substantially completely, so that the cargo 4 cannot accidentally escape through the loading opening 8. In the open position, the loading opening 8 of the storage compartment 3 is at least partially, and in the example shown substantially completely, released, so that the cargo 4 can be inserted into or removed from the storage compartment 3. Since the cargo 4 can have very different shapes and sizes, it is preferably not secured inside the storage compartment 3. The cargo 4 therefore preferably rests loosely on the floor 7 of the storage compartment 3. The storage compartment flap 9 prevents the cargo 4 from sliding out of the storage compartment 3.

[0042] By means of a flap actuator 14 with a single, i.e., exactly one, pivot actuator 15 (see Fig. 3A), the storage compartment flap 9 is moved from the closed to the open position. Thus, by activating the flap actuator 14, the storage compartment flap 9 can be pivoted about a first pivot axis 16 (see Fig. 3B), which is mounted on the structural component 1A. In the illustrated embodiment, the pivot actuator 15 is a single servo motor, which can be controlled to pivot the storage compartment flap 9 about the first pivot axis 16.

[0043] As can be seen in Figures 3A to 3E and in detail in Figures 4A to 7E, the pivot drive 15 is connected to the storage compartment door 9 via a gearbox 24. The gearbox 24 has a drive gear 25 on the side of the pivot drive 15 and an output gear 26 on the side of the storage compartment door 9. In the example shown, the drive gear 25 has a smaller diameter than the output gear 26, so that a gear ratio of more than 1, essentially 3 in the example shown, is achieved. The drive gear 25 has drive teeth 27 along a first circumferential section, which may be absent along a second circumferential section. The output gear 26 also has output teeth 28 along a first circumferential section, which may be absent along a second circumferential section.

[0044] The gearbox 24 has a locking device 29, which is configured to block the end positions of the storage compartment door 9. In the closed position of the storage compartment door 9, the locking device 29 blocks its rotation towards the open position. In the open position of the storage compartment door 9, the locking device 29 blocks its rotation towards the closed position. To block the end positions, the locking device 29 is designed to block the rotation of the output gear 26 from the closed or open position of the storage compartment door 9. By rotating the drive gear 25 by a release angle, the rotation of the output gear 26 can be released, so that by continuing the rotation of the drive gear 25 after rotation by the release angle, the torque of the rotary actuator is transmitted from the drive gear 25 to the output gear 26.

[0045] As can be seen from Figures 4A to 4E and especially from Figures 5A to 5E, the blocking device 29 in the illustrated embodiment has a first engagement element 30, which is coupled to the drive gear 25, i.e., rotates with the drive gear 25, and a second engagement element 31, which is coupled to the output gear 26, i.e., rotates with the output gear 26. The first engagement element 30 can be engaged with or disengaged from the second engagement element 31 by rotating the drive gear 25 by means of the rotary drive 15. In the illustrated embodiment, the first engagement element 30 is a first circular arc element and the second engagement element 31 is a second circular arc element. The first circular arc element can be connected to the second circular arc element with a virtually perfect fit. For this purpose, the first circular arc element can be convex and the second circular arc element can be concave.In the blocked state of the output gear 26, the first engagement element 30 engages with the second engagement element 31 in such a way that the rotation of the output gear 26 is blocked.

[0046] As can be seen from Figures 4A to 4E, 5A to 5E, and 6A to 6E, the drive gear 25 is also coupled to a drive assembly 32, which has a first drive or synchronization element 32A and a second drive or synchronization element 32B. Similarly, the output gear 26 is coupled to a drive assembly 33, which has a first drive part 33A and a second drive part 33B. When the storage compartment flap 9 is opened, the first drive element 32A, which rotates with the drive gear 25, comes into contact with the first drive element 33A, which is coupled to the output gear 26, i.e., rotates with the output gear 26, when the output gear 26 reaches the released state, i.e., after the drive gear 25 has rotated from the blocked closed position by the release angle.When the storage compartment flap 9 is closed, the second drive element 33B, in the released state of the output gear 26, is contacted by the second drive element 32B after the drive gear 25 pivots from the blocked open position by the release angle and is then engaged. The first drive element 32A and the second drive element 32B on the side of the drive gear 25 and the first drive element 33A and the second drive element 33B on the side of the output gear 26 have the function of synchronizing the meshing of the drive teeth 27 of the drive gear 25 with the output teeth 28 of the output gear 26.

[0047] The function of the gearbox can be seen from Figures 4A to 4E, Figures 5A to 5E, Figures 6A to 6E and Figures 7A to 7E.

[0048] Figures 4A, 5A, 6A, and 7A show the gearbox 24 in different views in the locked closed position of the storage compartment flap 9. In the closed position, the first engagement element 30 is engaged with the second engagement element 31. If a torque is applied to the output gear 26 via the storage compartment flap 9 in the direction of the open position, the rotation of the output gear 26 is prevented by the locking device 29 without the servo motor having to absorb the torque. The first 30 and the second engagement element 31 are arranged relative to each other in the engaged and locked positions, respectively, such that the torque on the output gear 26 is transferred to the bearing of the drive gear 25. This is because the force vector at the point of contact of the second engagement element 31 with the first engagement element 30 extends radially with respect to the first pivot axis 16.In the blocked closed position, the drive teeth 27 of the drive gear 25 are disengaged from the output teeth 28 of the output gear 26. The first drive element 32A, which rotates with the drive gear 25, is disengaged from the first drive element 33A, which rotates with the output gear 26.

[0049] Figures 4B, 5B, 6B, and 7B show, in different views, a first intermediate position during the movement of the storage compartment flap 9 from the closed position towards the open position. Starting from the blocked closed position according to Figures 4A, 5A, 6A, and 7A, the drive gear 25 is rotated by the release angle, which can be, for example, substantially 30°, until the first intermediate position is reached. In the first intermediate position, the first drive element 32A comes into contact with the first drive part 33, thereby aligning the drive teeth 27 with the output teeth 28.

[0050] Figures 4C, 5C, 6C, and 7C show, in different views, a second intermediate position during the movement of the storage compartment flap 9 from the closed position toward the open position. Further rotation of the drive gear 25, in the example shown by 135° from the first intermediate position, engages the drive teeth 27 with the output teeth 28, so that the rotation of the drive gear 25 is transmitted via the teeth to the output gear 26. In this way, the storage compartment flap 9 is pivoted toward the open position.

[0051] Figures 4D, 5D, 6D, and 7D show the gearbox 24 in different views in the unlocked open position of the storage compartment door 9, which is achieved by further rotation of the drive gear 25, in the example shown by 135° starting from the second intermediate position. In the unlocked open position, the storage compartment door 9 is open, but the locking device 29 is still in the release position.

[0052] Figures 4E, 5E, 6E, and 7E show the gearbox 24 in different views in the locked open position of the storage compartment flap 9. This position is reached by further rotation of the drive gear 25 through a locking angle, which preferably corresponds to the release angle, for example, 30°, after the unlocked open position of the storage compartment flap has been reached. During the transition from the unlocked to the locked open position, the drive gear 25 is rotated further through the locking angle without engaging the output gear 26, so that the output gear 26 is blocked by the locking device 29. The rotation of the drive gear 25 can be limited by an end stop 34.

[0053] The closing of the storage compartment flap 9 occurs from the locked open position (Figs. 4E, 5E, 6E and 7E) in the reverse direction. The synchronization of the gear teeth is achieved by the second drive element 32B on the drive gear side.

[0054] 25 or the second drive part 33B on the side of the output gear 26 accomplishes.
