Definitions

  • the present disclosure relates to a panel door for an aircraft.
  • the interior of a commercial aircraft typically includes several compartments, such as crew changing quarters, lavatories, galleys, and the like.
  • ingress and egress of these compartments are typically through a door or panel that functions as a partition between compartments by walling off the compartment when the door is in a closed position.
  • Doors of this type include both sliding doors and swinging doors.
  • Each of these types of doors have inherent drawbacks. Namely, swinging or hinged doors occupy a large amount of cross-aisle space when the door is open and the design of the aircraft must account for the free space needed to accommodate the arc of the door as it transitions open.
  • the present disclosure relates to a two panel door having a first panel hinged to the door frame and a second panel coupled to the frame by a linkage that includes a rotating arm.
  • the rotating arm reduces the arc traveled by the second panel (and thus the door in general) and results in a door with less width, weight, and covers the same area without unduly monopolizing cross-aisle space.
  • the door when opened is roughly half as wide as when it is closed, allowing for a more narrow aisle or, alternatively, leaving more aisle space available for cross traffic.
  • narrow aisle aircraft the use of a bi-fold door can be replaced with the implementations described by the present disclosure.
  • the present disclosure relates to a telescoping panel door for an aircraft compartment, including a first panel configured for hinged connection to a vertical surface of a door frame, a second panel, a linkage fixing a distance that the second panel can extend from the vertical surface of the door frame, where the second panel is configured for connection to a horizontal surface of the door frame via the linkage, and a low resistance telescoping mechanism comprising an engagement structure of the first panel configured for sliding translation with a complementary structure of the second panel.
  • the telescoping panel door upon installation to the door frame, may operate such that in a closed configuration, a vertical edge of the first panel is adjacent to a vertical edge of the second panel, and in an open configuration, a compartment-facing surface of the first panel is adjacent to an exterior-facing surface of the second panel.
  • the present disclosure relates to a telescoping panel door for an aircraft compartment including a first panel configured for hinged connection to a first surface of a door frame, a second panel, a first linkage fixing a distance that the second panel can extend from the first surface of the door frame, where the second panel is configured for connection to a second surface of the door frame via the first linkage, and a low resistance telescoping mechanism comprising an engagement structure of the first panel configured for sliding extension and retraction of one of the panels into the other of the panels.
  • the door upon installation, operates such that in a closed configuration, a vertical edge of the first panel is proximate to a vertical edge of the second panel, and in an open configuration, one panel is enclosed within the hollow portion of the other panel.

  • a translating door 10 that can be a door in an aircraft, vessel, or other vehicle is disclosed.
  • the translating door 10 includes at least two panels with a first panel 12 connected to door frame 14 via a hinge or set of hinges, such as the piano hinge 16, and a second panel 18 that is slidingly engaged with the first panel 12 and extends therefrom.
  • the first panel 12 may be attached to the frame 14 in a pivoting arrangement and a width of the first panel 12 can span substantially half of a width of a doorway, such as doorway to an entrance for an aircraft lavatory.
  • a handle or release lever 20 may be provided in the first panel 12 to assist in opening and closing the door 10.
  • the first panel 12 may also be provided with at least one horizontal groove or slot 22, 24 (two, as illustrated), as set forth more fully below.
  • the operation of the first panel 12 is relatively simple, swinging about a fixed point on a hinge or hinges 16 between an open position and a closed position. In the closed position, the first panel 12 is substantially in-line with the doorway.
  • the first panel 12 may occupy approximately one half of a door frame area, and the second panel 18 may also occupy approximately one half of the door frame area.
  • the second panel 18 of the translating door 10 is attached to the first panel 12 through a wheel 23 and slot arrangement where the wheels are captured on tracks in the horizontal slots 22, 24 or grooves, such that the second panel 18 is carried by the wheels 24 to move relative to the first panel 12 in a sliding or translating relationship such that the second panel 18 slides along a surface on one side of the first panel 12 as the door 10 is opened or closed.
  • the wheels 23 of the second panel 18, in other embodiments are replaced with other structures that allow the second panel 18 to glide or extend outward from the first panel 12 without undue friction or resistance, such as drawer slides.
  • the second panel 18 is sized to be approximately the same width as the first panel 12, when fully extended away from the first panel 12 (in the direction away from the hinged connection on the first panel) the second panel 18 will cooperate with the first panel 12 to completely cover and occlude the door frame 14 in a reliable manner. That is, the first and second panels 12, 18 have a combined width that when fully extended fill the doorway when the door 10 is closed by virtue of the full extension of the second panel 18 along and within the horizontal grooves or slots 22,24 of the first panel 12.
  • the second panel 18 is connected along an upper edge 26 to the door frame 14 by a linkage 28 such as a rigid bar.
  • the linkage 28 may be fixed at a first end 30 to the second panel 18 at an inner edge 32 that is closest to the piano hinge 16, and may be fixed at a second end 34 in a pivoting connection to the door frame 14 at approximately one quarter of a distance between sides of the door frame 14, closest to a side 36 with the hinge that connects to the first panel 12 (See FIGs. 2A-2E).
  • the linkage 28 is replaced by a flexible linkage or spring(s).
  • the linkage 28 is replaced with a retractable chain.
  • FIGs. 2A-2E show a sequence of the two panels 12, 18 as the door 10 transitions from fully closed in FIG. 2A to fully open in FIG. 2E.
  • the translating door 10 is fully closed and lies in a plane of the doorway.
  • a depth (or thickness) of the door 10 corresponds to a thickness of a single panel for an entire length of the door 10 except for where the two panels 12, 18 are joined together, creating space on both sides of the door itself.
  • FIG. 2B shows the door 10 as slightly ajar as the door 10 begins to open.
  • the first panel 12 is hinged to the door frame 14 at hinge 16 and moves in a predictable arc about the hinged connection.
  • the second panel 18 is prevented from following the same arc due to a fixed connection of the inner edge 32 with the door frame via the linkage 28.
  • the second panel 18 is retracted or constrained along a surface on one side of the first panel 12 within the horizontal grooves or slots 22, 24, and the door "shortens" in length as a result.
  • the door 10 is approximately halfway open and the second panel 18 is further withdrawn or retracted past the first panel 12 as the door continues to shorten, and an amount of overlap between the first panel 12 and the second panel 18 increases.
  • the fixed connection of the linkage 28 at the second panel 18 pulls the second panel along the first panel 12 such that a combined width (negating overlap) of the first and second panels 12, 18 is effectively halved when the door 10 reaches a fully opened position (FIG. 2E).
  • FIG. 2D the first panel 12 is opened more than halfway, and the second panel 18 has almost completely moved in alignment with the first panel such that a width of the door 10 is significantly reduced.
  • FIG. 2E the linkage 28 has retracted the second panel 18 into complete alignment with the first panel 12 such that a width of the second panel 18 completely overlaps a width of the first panel 12.
  • the width of the door 10 now coincides with the width of the first panel 12 as the second panel 18 is hidden behind the first panel 12.
  • the translating door 10 of the present disclosure extends only approximately halfway into the lavatory when fully opened as compared with a traditional door, yielding greater mobility and comfort to the occupant without any loss of function.
  • FIG. 3 illustrates a perspective view of the first and second panels 12, 18 in the closed (extended) position.
  • the horizontal slot 22 in the first panel is shown, and the wheel 23 or other engagement mechanism is shown in shadow that couple the two panels 12,18 together.
  • a pivoting extension 50 such as a coat hook, can be positioned just adjacent an edge of the second panel 18.
  • the extension 50 is a lever that can pivot horizontally or vertically as the second panel 18 slides back and forth along a surface on one side of the first panel 12 as the door 10 is opened and closed.
  • extension 50 when the extension 50 is pivoted out of a plane of the first panel 12, the second panel 18 is blocked from sliding across a surface of the first panel 12 by interference of the extension 50.
  • a reliable and efficient locking mechanism can be formed from the extension 50, which can also function as a dual purpose coat hook or the like.
  • FIG. 4 illustrates the linkage 28 between the second panel 18 and the door frame 14.
  • the linkage 28 connects the second panel 18 at a top edge 26 with a pin or other mechanical arrangement that allows for rotation of the linkage 28 about the connection so that the linkage 28 can track the second panel 18 as the linkage 28 rotates around the primary hinge 16.
  • the bar, rod, or other structure that forms the linkage 28 is connected to the door frame 14 or an immediate adjacent location by a similar pivoting coupling that allows for the linkage 28 to swivel at the fixed location.
  • the linkage 28 limits the travel of the second panel 18 from the fixed connection point of the bar, thereby causing the second panel 18 to slide along the horizontal grooves 22, 24 from an extended position to a retracted position as the first panel 12 swings in an arc away from the fixed connection point. In this manner, the width of the door 10 automatically shortens to (roughly) half of its extended length when in the fully open position.
  • the horizontal grooves or slots 22, 24 on the first panel 12 establish tracks or raceways that permit a smooth rolling or sliding motion across their surfaces, so that the second panel 18 can move easily and freely along the first panel. This is particularly important where there is only one linkage 28 maneuvering the second panel 18 at the top 26 of the door 10, because friction or sticking of the track will cause issues with torqueing or twisting of the panels with a resultant loss of effectiveness.
  • the frame 14, linkage 28, and other associated components are associated with an upper door frame, but it can also be understood that the frame 14 and linkage can also be part of a lower door frame or both an upper door frame and a lower door frame.
  • the result is a two panel door for an aircraft compartment that has a first panel hingedly connected to a door frame, the first panel having a width of approximately half of a door frame to which it is mounted, and a second panel mounted on the first panel for sliding translation thereon, the second panel extending parallel to the first panel in a sliding arrangement.
  • the first panel is coupled to the door frame via a hinge and the second panel is coupled to the door frame via a linkage, the linkage fixing a distance that the second panel can extend from the door frame as the first panel swings about its hinged connection is a circular arc.
  • the two panel door operates such that the ends of the panels 60,32 are adjacent in the closed configuration and the faces 62,64 of the panels 12, 18 are adjacent to each other in the open configuration.
  • the translating door can be used in applications where door strength is an important factor, such as in the case of aircraft lavatory doors.
  • the aircraft panel door can also be a telescoping door 500 where a second panel 506 slides into and out of a hollow portion 510 of a first panel 504 as the telescoping door 500 is opened and closed.
  • the telescoping door 500 operates in a substantially similar way as the translating door 10 described previously.
  • FIG. 5 provides an illustration of telescoping operations of the door 500 and can also include other components described previously with respect to the translating door 10, such as a door frame, release lever, pivoting extension, etc.
  • the telescoping door 500 can be used in applications where a thickness of a door aperture is limited, such as in the case of galley doors in an aircraft due to the fact that a thickness of an overlapping portion 508 of the door 500 does not increase as the second panel 506 slides into and out of the cavity 510 of the first panel 504 as the door 500 moves between open and closed positions.
  • the first panel 504 of the door 500 is connected to a frame (not shown) via a hinge 502 or set of hinges.
  • the hinge 502 can be a piano hinge such as with the hinge 16 described previously or can be a garage hinge or simple pivoting door.
  • the door 500 can be vertical swinging or horizontal swinging based on a function and location of the door 500. For example, for a storage compartment in a forward galley of an aircraft, the door 500 may swing vertically, and the hinge 502 is located above or below the first panel 504 between a horizontal surface of the first panel 504 and the door frame when the door 500 is in a closed position.
  • the door 500 may swing horizontally, and the hinge 502 is between a vertical surface of the first panel 504 and the door frame on a left side or right side of the first panel 504 based on a direction the door 500 rotates as the door is opened or closed.
  • the first panel 504 operates by swinging about a fixed point on the hinge 502 between an open position and a closed position. In the closed position, the first panel 504 is substantially in-line with the doorway where the first panel 504 occupies approximately one half of a door frame area, and the second panel 506 also occupies approximately one half of the door frame area.
  • the second panel 506 of the telescoping door 500 can also be attached to the first panel 504 through a guiding mechanism such as a wheel and slot arrangement where the wheels are captured on tracks in the horizontal slots or grooves, such that the second panel 506 is carried by the wheels to move relative to the first panel 504 in a sliding or telescoping relationship such that the second panel 506 slides along one or both inner surfaces of the first panel 504 as the door 500 is opened or closed.
  • the wheels of the second panel 506 can be replaced with other structures that allow the second panel 506 to glide or extend outward or inward within the first panel 504 without undue friction or resistance, such as drawer slides.
  • the second panel 506 slides freely within the hollow portion 510 of the first panel 504 without any type of guiding mechanism.
  • the second panel 506 is sized to be approximately the same width as the first panel 504, when fully extended away from the first panel 504 (in the direction away from the hinged connection on the first panel), the second panel 506 cooperates with the first panel 504 to completely cover and occlude the door frame in a reliable manner. That is, the first and second panels 504, 506 have a combined width that when fully extended close the doorway when the door 500 is closed by virtue of the full extension of the second panel 506 from the first panel 504.
  • the second panel 506 is withdrawn into the hollow portion 510 of the first panel 504, as indicated by the overlapping portion 508.
  • the width of the second panel 506 is substantially withdrawn into the hollow portion 510 of the first panel 504 so that the second panel 506 is enclosed within the hollow portion 510 of the first panel 504.
  • one or more inner surfaces of the first panel 504 are adjacent to one or more exterior surfaces of the second panel 506.
  • a thickness of the second panel 506 is less than a thickness of the first panel 504 to facilitate the extension and retraction of the second panel 506 within the hollow portion 510 of the first panel 504 so that the second panel 506 can move freely and easily within the hollow portion 510 of the first panel 504.
  • the second panel 506 is connected along an edge to the door frame by at least one linkage such as a rigid bar or control arm (see linkage 610 in FIGs. 6B-6C).
  • the second panel 506 can be connected to the door frame by the linkage on one side or both sides of the second panel 506.
  • the linkage may be fixed at a first end to the second panel 506 at an inner edge that is closest to the hinge 502, and may be fixed at a second end in a pivoting connection to the door frame at approximately one quarter of a distance between sides of the door frame, closest to a side with the hinge that connects to the first panel 506 (see FIGs. 6B-6C and 7B).
  • other types of linkages can also be used, such as retractable chains, springs, or flexible linkages that connect the second panel 506 to the door frame, as discussed above in relation to the second panel 18 of the telescoping door.
  • an edge of the first panel 504 on the same side of the door 500 as the linkage includes a slot 512 or groove that extends across the width of the first panel 504 that allows the linkage to remain in contact with the second panel 506 as the second panel 506 is withdrawn into the hollow portion 510 of the first panel 504 by providing accessibility for the linkage to connect to the second panel 506 when the second panel 506 is within the hollow portion 510 of the first panel 504.
  • the slot 512 and the linkage function as the guiding mechanism that allows the second panel 506 to glide or extend outward or inward within the first panel 504 without undue friction or resistance.
  • the second panel 506 may include a hollow portion and be drawn to substantially cover the first panel in the open configuration, and pull away from the first panel to expose the first panel in the closed configuration.
  • the linkage would work substantially the same.
  • FIGs. 6A-6C show a sequence of opening a two-panel vertical swinging telescoping door 600 from fully closed in FIG. 6 A to fully open in FIG. 6C.

  • a fixed connection of the linkage 710 at the second panel 704 pulls the second panel along the first panel 702 such that a combined width of the first and second panels 702, 704 is effectively halved when the door 700 reaches a fully opened position (FIG. 7C).
  • an edge of the first panel 702 on the same side of the door 700 as the linkage 710 can include a slot 712 or groove that extends across the width of the first panel 702 which allows the linkage 710 to remain in contact with the second panel 704 as the second panel 704 is withdrawn into the hollow portion of the first panel 702.
  • the slot 712 and the linkage 710 function as the guiding mechanism which allows the second panel 704 to glide or extend outward or inward within the first panel 702 without undue friction or resistance.
  • the door 700 is in a fully opened position, and the linkages 710 have retracted the second panel 704 into complete alignment with the first panel 702 such that a width of the second panel 704 is substantially overlapped by a width of the first panel 702.
  • the width of the door 700 now coincides with the width of the first panel 702 as the second panel 704 is hidden within the first panel 702.
  • the telescoping door 700 of the present disclosure extends only approximately halfway into the open galley space when fully opened as compared with a traditional door, yielding greater mobility and comfort to aircraft employees working in an around the galley without any loss of function.
  • the telescoping panel door implementations described herein can also be applied to other types of aircraft doors.
  • implementing the telescoping doors for chilled galley cart compartment doors provide fewer gaps to seal and intrude less into a work area when open.
  • the vertical swinging telescoping doors can be used to enclose overhead storage bins in order to reduce an amount of projection of the doors into an aisle- way of an aircraft, which allows for better illumination during passenger loading and unloading due to reduced blocking of the overhead lights by the telescoping doors.
  • the telescoping overhead bin doors provide more head clearance for flight crew when the doors are in an open position.
  • a flight deck entry door can also be implemented as a telescoping door.
  • the forward cabin on an aircraft is a very cramped compartment, and a telescoping flight deck door would provide better functionality and ease of use due to the reduced space intrusion when open while providing more security to the flight deck than a conventional bi-fold door.
  • a mid-cabin closet door could also be implemented as a telescoping panel door as described previously herein.
  • the result is a two panel door for an aircraft compartment that has a first panel hingedly connected to a door frame, the first panel having a width of approximately half of a door frame to which it is mounted, and a second panel mounted on the first panel for telescoping therein, the second panel extending parallel to the first panel within a hollow portion of the first panel in a sliding arrangement.
  • the first panel may be coupled to the door frame via a hinge and the second panel may be coupled to the door frame via a linkage, the linkage fixing a distance that the second panel can extend from the door frame as the first panel swings about its hinged connection is a circular arc.
  • the telescoping door can be used in applications where a thickness of a door aperture is limited, such as in the case of galley doors.
  • the aircraft doors can have a curved shape, such as in the case of the overhead bin doors, and therefore the first panel and second panel also have a curved shape.
  • the translating or telescoping operation of the curved first and second panels function in a substantially similar way to the telescoping or translating operation of the flat, planar-shaped doors described previously herein.

Abstract

L'invention concerne, selon un mode de réalisation préféré, une porte à panneaux du type télescopique pour un compartiment d'aéronef comprenant un premier panneau configuré pour une liaison articulée à une surface d'un cadre de porte, un deuxième panneau, et une tringlerie à des fins de fixation sur une distance telle que le deuxième panneau peut s'étendre depuis le cadre de porte, le deuxième panneau étant configuré pour être relié au cadre de porte par l'intermédiaire de la tringlerie. La porte fonctionne de telle sorte que, dans une position fermée, le deuxième panneau est étendu depuis une partie intérieure du premier panneau, les premier et deuxième panneaux coopèrent pour recouvrir entièrement une ouverture définie par le cadre de porte, et la tringlerie est généralement parallèle au plan défini par le cadre de porte. Dans une position ouverte, le deuxième panneau est rétracté dans la partie intérieure du premier panneau par le fonctionnement de la tringlerie et les premier et deuxième panneaux sont imbriqués pour réduire une distance couverte par les panneaux.
