Description

Technical Field

[0001] The invention belongs to the field of aircraft structure design, and in particular relates to a handle device with an outer opening function for an aircraft ventilation window. Background Art

[0002] In current civil aircraft, a push-type handle device is installed on the ventilation window for opening and closing the ventilation window.

[0003] As the emergency evacuation channel for crew members, the ventilation windows of civil aircraft must comply with the emergency evacuation requirements in the civil aircraft airworthiness regulations. In some cases, such as passenger-to-cargo aircraft, the right service door needs to be blocked, and the corresponding right ventilation window must have the function of opening from the outside.

[0004] In the prior art, for example, the ventilation window of the Boeing 737 has an outer opening function, and its inner handle is a side grip type, with the actuating end and the locking end in direct contact. When the inner handle device is used, the handle button is pressed to directly drive the locking end to complete the unlocking action, and then the window is opened; the outer handle is a stretching type, and the motion is transmitted to a driving shaft through a series of rods; in addition, a set of linkage devices is integrated on the inner handle to realize the linkage of the inner and outer handles. When performing the outer opening action, the linkage mechanism is driven by the driving shaft to transmit the motion to the inner handle actuating end, and then from the actuating end to the locking end, so as to unlock the inner handle and then open the window; when performing the inner opening action, the inner handle mechanism moves normally and is not transmitted to the outer handle.

[0005] The linkage method of the existing handle currently has the following problems:

[0006] (1) Since the actuating end and locking end of the inner handle are in direct contact, there is a risk that the handle lock will be accidentally unlocked if a person inside the aircraft accidentally touches the button;

[0007] (2) The inner and outer handle linkage devices are directly connected to the actuating end of the inner handle. When performing an external opening operation, the movement must be transmitted to the locking end through the actuating end of the inner handle. Therefore, the transmission path is not direct. If the actuating end of the inner handle fails, the movement of the outer handle cannot be transmitted to the locking end, and then the external window cannot be opened. This leads to the risk of not being able to open the ventilation window from outside the aircraft in an emergency.

[0008] Therefore, there is still a need to further improve the structure of the existing handle device. Summary of the invention

[0009] In view of the above-mentioned problems in the prior art, an object of the present invention is to provide a handle device which can reduce or eliminate the risk of accidentally opening the ventilation window due to accidental touching of the handle device button, and allow the function of directly opening the window outside the aircraft to meet the dual scenario requirements of normal prevention of misoperation inside the aircraft and emergency opening outside the aircraft.

[0010] To solve the above problems, the present invention provides a handle device for an aircraft ventilation window, wherein the handle device comprises: an inner handle portion, the inner handle portion comprises a transmission rod and an inner handle compression spring, wherein the transmission rod has a transmission rod actuating end, and the inner handle compression spring is sleeved on at least a portion of the transmission rod; a locking portion, the locking portion comprises a base and a lock tongue, the lock tongue is pivotally installed in the base, the lock tongue has a lock tongue actuating end located on one side of the pivot axis and a lock tongue locking end located on the other side opposite to the pivot axis, and an outer handle portion, the outer handle portion and the inner handle portion extend in opposite directions, the outer handle portion comprises a rotating shaft and a connecting member, wherein the rotating shaft has a rotating shaft actuating end, and the connecting member causes the rotating shaft actuating end to actuate between the rotating shaft actuating end and the lock tongue locking end. The lock tongue is in its locked position when the inner handle compression spring is compressed more than a predetermined distance and the drive rod actuating end of the drive rod abuts against and actuates the lock tongue actuating end of the lock tongue, and / or when the shaft is rotated more than a predetermined angle and the shaft actuating end of the shaft actuates against the connecting member and actuates the lock tongue locking end of the lock tongue via the connecting member, the lock tongue is in its unlocked position.

[0011] In a second example of the handle device, optionally including the first example, the connecting member of the outer handle portion includes a guide block, the guide block has a ramp portion and a straight portion, and wherein the straight portion of the guide block is activatably connected to a rotating shaft protrusion at the rotating shaft actuating end of the rotating shaft, and wherein the ramp portion of the guide block is in abutment contact with a lock tongue protrusion at a lock tongue locking end of the lock tongue.

[0012] In a third example of the handle device, which optionally includes one or more of the first example and the second example, the inclination angle of the slope portion is 45°.

[0013] In a fourth example of the handle device, optionally including one or more or each of the first to third examples, the guide block is arranged in the base, and the top wall of the base includes a first groove, wherein the guide block passes through the first groove of the base and partially protrudes from the base.

[0014] In a fifth example of the handle device, optionally including one or more or each of the first to fourth examples, the connecting member of the outer handle portion also includes a connecting rod, the connecting rod is arranged in the base, and the top wall of the base also includes a second groove, wherein the connecting rod is connected to the straight portion of the guide block at the first end of the connecting rod, and is connected to the shaft protrusion at the shaft actuating end of the shaft at the second end of the connecting rod, and wherein the connecting rod passes through the second groove of the base and partially protrudes from the base.

[0015] In a sixth example of the handle device, optionally including one or more or each of the first to fifth examples, the guide block is constrained by the groove shape of the first groove and has only a degree of freedom in the horizontal direction, and the connecting rod is constrained by the groove shape of the second groove and has only a degree of freedom in the horizontal direction.

[0016] In the seventh example of the handle device, one or more or each of the first to sixth examples may be optionally included, and the top wall of the base is further provided with a rebound portion, the rebound portion comprising a base convex portion, a base compression spring and a pin, wherein the pin is connected to the base convex portion, wherein the base compression spring is sleeved on the pin, and one end of the base compression spring is in contact with the base convex portion, and the other end is in contact with the straight portion of the guide block.

[0017] In an eighth example of the handle device, optionally including one or more or each of the first to seventh examples, the handle device further includes: a box cover, which covers and shields the rebound portion and at least a portion of the top wall of the base.

[0020] The present invention adopts a simple structure to solve the problem of inner and outer handle linkage under the conditions of ensuring the inner opening anti-mistouch and the outer opening directness. Since the linkage device is directly connected to the lock tongue through the guide block, the actuation requirement of the inner handle is bypassed. By utilizing its high-pair motion characteristics, when performing the outer opening operation, the motion will be directly transmitted to the locking end of the lock tongue, so that it no longer has an operating idle stroke. When performing the inner opening operation, the inner handle still has the anti-mistouch function and does not transmit the motion to the outer handle, which meets the scene requirements of normal anti-mistouch operation inside the machine and emergency opening outside the machine.

[0053] The present invention will be further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0054] In various embodiments of the present invention, the “horizontal direction” is defined as Figure 1-3 The left and right directions of Figure 1-3 Up and down direction.

[0055] Figure 1 The handle device for an aircraft ventilation window of a preferred embodiment of the present invention is schematically shown, which mainly comprises an inner handle portion 10 for providing an internal unlocking function of the ventilation window, a locking portion for locking the ventilation window, and an outer handle portion for providing an internal and external opening function of the ventilation window. The inner handle portion and the outer handle portion are fixedly attached to both ends of the locking portion. Figure 1 As viewed from a perspective view of FIG. 1 , the inner handle portion and the outer handle portion extend substantially in opposite directions at both ends of the locking portion.

[0056] In this preferred embodiment, the inner handle portion 10 includes a transmission rod 8 and an inner handle compression spring 9. The transmission rod 8 may be an elongated round rod, and has a transmission rod actuation end 8a along the longitudinal extension direction of the rod for actuating the locking tongue 14 in the locking portion. The inner handle compression spring 9 may be sleeved on at least a portion of the transmission rod 8.

[0057] Preferably, in order to increase the safety of the handle device during use and avoid accidental opening of the ventilation window due to misoperation, the transmission rod 8 of the inner handle portion 10 of the handle device has a reserved idle stroke, so that in the initial stage of operation of the inner handle portion 10, due to the idle stroke of the transmission rod 8, the lock tongue 14 in the locking portion will not be actuated, but will remain in place, and the ventilation window will not be opened by mistake.

[0058] In a preferred embodiment, the locking portion comprises a base 11 and a locking tongue 14. The locking tongue 14 can be pivotally mounted in the base 11, and has a locking tongue actuating end 14a located on one side of the pivot axis and a locking tongue locking end 14b located on the other side of the pivot axis.

[0059] In a preferred embodiment, the outer handle portion may include a shaft 16 and a coupling member. The shaft 16 has a shaft actuation end 16 a, and the coupling member is actuably connected between the shaft actuation end 16 a and the locking end 14 b of the locking tongue 14 .

[0060] Preferably, the lock tongue protrusion 141 will perform high-pair motion along the slope portion 151. By utilizing its high-pair motion characteristics, when performing an outward opening operation, the motion will be directly transmitted to the lock tongue locking end, so that it no longer has an operating idle stroke.

[0061] Preferably, the locking tongue 14 has a locking position and an unlocking position.

[0062] The lock tongue 14 can be in its locked position only when the following two conditions are met, that is, when the transmission rod 8 is held by the inner handle compression spring 9 so that the actuating end of the transmission rod 8 is spaced a predetermined distance from the lock tongue actuating end 14a of the lock tongue 14, and when the rotating shaft 16 has not rotated more than a predetermined angle so that the rotating shaft actuating end 16a of the rotating shaft 16 has not actuated the lock tongue locking end 14b of the lock tongue 14.

[0063] In addition, when the inner handle compression spring 9 is compressed beyond a predetermined distance and the transmission rod actuating end 8a of the transmission rod 8 abuts against and actuates the lock tongue actuating end 14a of the lock tongue 14, and / or when the rotating shaft 16 is rotated beyond a predetermined angle and the rotating shaft actuating end 16a of the rotating shaft 16 abuts against the connecting member and actuates the lock tongue locking end 14b of the lock tongue 14 via the connecting member, the lock tongue 14 will be in its unlocked position.

[0064] The locking portion may further include a torsion spring arranged around the pivot axis, one end of the torsion spring abutting against the lock tongue 14, and the other end of the torsion spring abutting against the base 11. When the lock tongue 14 is pivoted to the unlocking position under the actuation of the transmission rod 8, the torsion spring generates elastic deformation, and the elastic force generated by the elastic deformation tends to restore the lock tongue 14 to its locking position, such as the position shown in FIG.

[0065] When the force of the transmission rod 8 is removed, the elastic force of the torsion spring acts, and the locking tongue 14 pivots around the pivot axis to return to the locking position.

[0066] According to a preferred embodiment of the present invention, the coupling member of the outer handle portion comprises a guide block 15 having a slope portion 151 and a straight portion 152 .

[0067] Preferably, the straight portion 152 of the guide block 15 is operatively connected to the shaft protrusion 161 at the shaft actuating end 16 a of the shaft 16 , so as to convert the rotational motion of the shaft 16 into the translational motion of the guide block 15 in the horizontal direction.

[0068] Preferably, the slope portion 151 of the guide block 15 abuts against the lock tongue protrusion 141 of the lock tongue locking end 14b of the lock tongue 14, and when the rotating shaft 16 rotates beyond a predetermined angle, the guide block 15 moves in the horizontal direction beyond a predetermined distance, and the slope portion 151 translates so that its slope surface abuts against the lock tongue protrusion 141, and the lock tongue locking end 14b is lifted upward in the vertical direction as it translates, and finally the lock tongue 14 enters the unlocking position.

[0069] In a preferred embodiment, the inclination angle of the slope portion 151 is determined according to the actuation stroke of a specific application, and may be approximately between 30° and 60°, preferably 45°.

[0070] In a preferred embodiment, the connecting member of the outer handle portion may also include a connecting rod 17, wherein the connecting rod 17 is connected to the straight end 152 of the guide block 15 at the first end 171 of the connecting rod, and is connected to the shaft protrusion 161 at the shaft actuating end 16a of the shaft 16 at the second end 172 of the connecting rod, so as to transition the rotational movement of the shaft 16 into the translational movement of the guide block 15 in the horizontal direction.

[0071] Preferably, the guide block 15 is disposed in the base 11, and the top wall of the base 11 includes a first groove 112, the guide block 15 passes through the first groove 112 of the base 11 and partially protrudes upward from the base 11. The connecting rod 17 is also disposed in the base 11, and the top wall of the base 11 also includes a second groove 113, the connecting rod 17 passes through the second groove 113 of the base 11 and partially protrudes from the base 11.

[0072] In a preferred embodiment, the guide block 15 is constrained by the groove shape of the first groove 112 and has only a horizontal degree of freedom, and the connecting rod 17 is constrained by the groove shape of the second groove 113 and has only a horizontal degree of freedom. It can be understood that the limiting form of the connecting member is not limited to slotting.

[0073] It is understandable that the form of the connecting member is not limited to the guide block 15 and the connecting rod 17, and can also be a cam, a shaft with a shoulder, etc. Such a component with a protruding profile can actuate the lock tongue protrusion 141 as the shaft 16 rotates.

[0074] In an optional embodiment, the connecting rod 17 may be a shaft with a boss, and the limiting portion may not be the grooves 112 and 113 but a hole on the boss. Guidance may be achieved through hole-shaft cooperation, and the limiting function may be achieved through the shaft shoulder.

[0075] In a preferred embodiment, the top wall of the base 11 may also be provided with a rebound portion, which includes a base protrusion 111, a base compression spring 18, and a pin 19. The pin 19 is connected to the base protrusion 111 to limit the axial movement of the pin 19, which can be achieved by interference fit or by installing shaft retaining rings on both sides.

[0076] Preferably, the straight portion 152 of the guide block 15 is connected to the pin 19 by a clearance fit to limit the axial movement of the pin (19).

[0077] Preferably, the base compression spring 18 is sleeved on the pin 19 , and one end of the base compression spring 18 contacts the base protrusion 111 , and the other end contacts the straight end 152 of the guide block 15 .

[0078] exist Figure 3 When the locking tongue 14 is actuated on the slope surface of the slope portion 151 of the guide block 15 and pivoted to the unlocked position, the base compression spring 18 generates elastic deformation, and the elastic force generated by the elastic deformation tends to restore the guide block 15 to its original position, such as the position shown in FIG. 1.

[0079] Then, if Figure 1 , 2 As shown, when the ramp surface of the guide block 15 is removed, the elastic force of the torsion spring acts, and the locking tongue 14 pivots around the pivot axis to return to the locking position.

[0080] According to a preferred embodiment of the present invention, the box further comprises a box cover 12, which covers and shields the resilient portion and at least a portion of the top wall of the base 11. The rotating shaft actuating end 16a and the rotating shaft protrusion 161 may also be disposed in the box cover 12.

[0081] Preferably, the box cover 12 may be provided with ears on both sides which are fixedly connected to the base 11 using fasteners.

[0082] In a preferred embodiment, the bottom of the base 11 is hollow and forms a receiving cavity. Preferably, the locking tongue 14 is pivotally mounted in the receiving cavity of the base 11 .

[0083] In addition, the handle device further comprises a lock plate 13, which is mounted on the open side of the accommodating cavity of the base 11, and the base 11 is rotatably mounted relative to the lock plate 13. A locking hole is formed on the lock plate 13. When the lock tongue 14 is in the locking position, the lock tongue locking end 14b of the lock tongue 14 is hooked and locked in the locking hole, so that the locking hole is lockedly engaged with the lock tongue locking end 14b of the lock tongue 14. When the lock tongue locking end 14b is disengaged from the locking hole, the base 11 can rotate relative to the lock plate 13.

[0084] When performing an outward opening operation:

[0085] The first stage (unlocking stage): the shaft 16 is driven by an external handle, such as Figure 3 As shown in the figure, it rotates clockwise, at this time, the shaft protrusion 161 of the shaft 16 will push the guide block 15 and the connecting rod 17 to overcome the spring force of the base compression spring 18 and make axial movement in the first groove 112 and the second groove 113 along the pin 19 to the left in the horizontal direction, and at the same time, the roughly L-shaped lock tongue protrusion 141 will make a high-pair movement along the slope portion 151, and accordingly, the lock tongue locking end 14b of the lock tongue 14 will be lifted and disengaged from the locking hole of the lock plate 13, and when the connecting rod 17 moves to the leftmost end in the second groove 113, the two are in contact with the limit position, and the corresponding unlocking is completed. At this time, the lock tongue locking end 14b of the lock tongue 14 is completely out of the locking hole of the lock plate 13.

[0086] The second stage (window opening stage): After the unlocking stage is completed, the shaft 16 continues to rotate clockwise. At this time, the connecting rod 17 contacts the left end of the second groove 113 to limit the rotation. The rotation of the shaft 16 will directly drive the base 11 to rotate, that is, realize the window opening movement.

[0087] When performing an inner opening operation:

[0088] By pressing the actuating button of the inner handle 10, the transmission rod 8 is driven. When the transmission rod 8 moves through the idle stroke, the lock tongue actuating end 14a of the lock tongue 14 is actuated, and then the lock tongue locking end 14b is lifted and disengaged from the locking hole of the lock plate 13, and the lock is unlocked similarly to the above-mentioned external opening operation.

[0089] At this time, the locking tongue protrusion 141 is disengaged from the slope portion 151 of the guide block 15, and has no effect on the external handle.

[0090] The present invention adopts a simple structure to solve the problem of inner and outer handle linkage under the conditions of ensuring the inner opening anti-mistouch and the outer opening directness. Since the linkage device is directly connected to the lock tongue through the guide block, the actuation requirement of the inner handle is bypassed. By utilizing its high-pair motion characteristics, when performing the outer opening operation, the motion will be directly transmitted to the locking end of the lock tongue, so that it no longer has an operating idle stroke. When performing the inner opening operation, the inner handle still has the anti-mistouch function and does not transmit the motion to the outer handle, which meets the scene requirements of normal anti-mistouch operation inside the machine and emergency opening outside the machine.

[0091] The handle device according to the present invention has a transmission function when the external handle is operated in addition to the linkage function of the internal and external handles. When opening the ventilation window, the first step is to unlock the handle inside the ventilation window, and the second step is to rotate the handle inside the ventilation window and then open the ventilation window.

[0092] After the shaft 16 drives the linkage mechanism to unlock the internal handle, the shaft 16 continues to rotate to push the connecting rod 17 to slide in the second groove 113. When it contacts the left end of the second groove 113, it plays a limiting role. The rotation of the shaft 16 directly drives the internal handle to rotate. The final effect is that the operation of the external handle realizes the unlocking and rotation of the internal handle through the linkage mechanism, and the actions have a chronological sequence.

[0093] Although various embodiments have been described above, it should be understood that they have been presented by way of example and not limitation. It will be apparent to those skilled in the relevant art that the disclosed subject matter can be implemented in other specific forms without departing from its spirit and essential characteristics.

[0094] The present disclosure also includes various modifications and variations within the scope of equivalents. In addition, various combinations and modes, and other combinations and modes including only one element, more than one element, or less than one element also fall within the scope and concept of the present disclosure.

[0095] Therefore, the embodiments described above are considered to be illustrative and non-restrictive in all aspects, and are not to be used as a basis for imposing any limitation on the present invention.
