Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Provisional Application No. 62 / 927423, filed on October 29, 2019, entitled “DISENGAGE ONE PIECE DOOR FROM PRIMARY RAIL SYSTEM”, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] The field of the present invention relates to passenger seating units having passenger seating areas, such as mini suites, and more specifically, to privacy screens, walls or doors that separate passenger seating areas from aisle areas or other public areas. Background Technology

[0004] Many modes of transportation, such as passenger airplanes, buses, trains, ships, and cars, include seats that passengers can use during travel. Some modes of transportation include seats with passenger seating units (such as mini-suites) that have privacy shells or screens, giving passengers a sense of enclosure. For example, privacy screens, walls, or sliding doors can be provided to separate the passenger seating area, including the passenger seats, from aisle areas or other public areas. To completely enclose the passenger seating area, some passenger seating units may include privacy doors or screens (collectively referred to as "privacy features"), and airline crew and / or other passengers cannot see into and / or enter the suite without moving the door.

[0005] While passenger comfort and privacy are important considerations in passenger seat unit design, these units are also subject to safety regulations set by governments or other standards-setting organizations. For example, some regulations require that doors not be installed or deployed between any passenger and any emergency exit space or aisle during specific situations such as taxiing, takeoff, and landing (TTL). Other regulations may require that doors must be able to open even if adjacent aisles are congested or if door components malfunction. Therefore, any privacy features that may be associated with passenger seats must allow for safe and timely exit from the passenger seat unit. Summary of the Invention

[0036] The embodiments described in this invention provide passenger seat units with door assemblies. While the use of passenger seat units in aircraft and / or aircraft seats is discussed, they are by no means limited thereto. Rather, embodiments of the passenger seat units can be used in other modes of transport and / or used with any type of seat, or otherwise as required. Furthermore, similar door assemblies can be used in other enclosed areas of the transport, such as toilets.

[0037] According to certain embodiments of the present invention, such as Figure 1A-1C As shown, the passenger seat unit 100 may include a privacy housing 106 and a door assembly 101 including a wall portion 102 and a door 104. The wall portion 102 may be part of the privacy housing 106, which defines a passenger seat area 116 of the passenger seat unit 100. Figure 1A-1C As best illustrated herein, wall portion 102 includes an opening 108 that allows access to and exit from passenger seating area 116. The specific shape of opening 108 should not be considered a limitation of this disclosure. Various passenger features may be provided in passenger seating area 116 as needed, including but not limited to passenger seats, beds, tray tables, in-flight entertainment screens, storage compartments, closets, reading lights, various other features that passengers may use, and / or various other combinations or sub-combinations of desired features. The shapes of wall portion 102, door 104, privacy shell 106, and passenger features included in passenger seating area 116 should not be considered a limitation of this disclosure.

[0038] The door 104 of the door assembly 101 is at least partially supported on the wall portion 102 and is movable relative to the fixed wall portion 102. For example, the door 104 is capable of moving in a forward direction (as indicated by arrow 110) and a backward direction (as indicated by arrow 112) (see FIG. 1). However, only the forward and backward directions are mentioned herein to provide a directional reference, and these forward and backward directions can be interchanged such that the forward direction can be represented by arrow 112, and the backward direction can be represented by arrow 112.

[0039] Optionally, door 104 may include a gripping feature that a passenger, attendant, or other individual may use to facilitate movement of door 104 between a forward position and a rearward position. In the forward position, for example, opening 108 is at least partially blocked by door 104 such that door 104 at least partially covers opening 108 to further close passenger seating area 116. In the rearward position, for example, opening 108 is at least partially unblocked by door 104.

[0040] In some respects, door 104 may be supported on wall portion 102 by various suitable mechanisms or devices, enabling door 104 to move in a front-back direction. As some non-limiting examples, door 104 may be able to slide along at least one translational track (e.g., track 114, passageway, rail, etc.), may be able to move via at least one roller, or may utilize at least one of various other mechanisms or devices as needed. For example, track 114 may be integrally formed with or connected to wall portion 102, and door 104 may be slidably connected to wall portion 102 via track 114. The at least one translational track may be of any suitable shape, such as straight, curved, arcuate, stepped, or any other desired shape.

[0041] In some embodiments, door 104 may be slidably connected to wall portion 102 and / or track 114, passageway, slide rail, etc. via carriage member 118, which may also be referred to herein as attachment plate. The following is in conjunction with... Figures 2A-3B Further details relating to the structure of carriage component 118 are discussed.

[0042] The carriage component 118 can be connected to the door 104 and can slide or move along the track 114 in a back-and-forth direction, thereby causing the door 104 to move. For example, as Figure 1B As illustrated, the carriage component 118 and the door 104 can slide as a unit relative to the wall portion 102 along the track 114. As shown, the carriage component 118 can be attached to the door 104 at the same location on the door 104, and therefore, when the carriage component 118 moves along the track 114, the door 104 can move along the track 114.

[0043] In some embodiments, door assembly 101 may include a locked state and an unlocked state. In the locked state, the carriage assembly remains in the same position coupled to door 104, and as described above, carriage assembly 118 and door 104 can move as a unit along track 114. In the unlocked state, as... Figure 1C As illustrated, when the carriage component 118 is held in a substantially fixed position along the track 114, the door 104 can slide relative to the carriage component 118 and the wall portion 102.

[0044] Door 104 may include Figure 1B The channels 120, tracks, slides, etc. shown herein allow the carriage member 118 to move along these channels 120, tracks, slides, etc., when the door assembly 101 is in the unlocked state. For example, the carriage member 118 may be releasably connected to the door 104 via the channels 120. When the door assembly 101 is in the unlocked state, the door 104 may move relative to the carriage member 118 and the wall portion 102 as at least a portion of the carriage member 118 travels along the channels 120.

[0045] By including at least two sliding rails, such as track 114 and channel 120, in the door assembly 101, the door 104 can still move to the open or rearmost position even if one of the sliding rails fails or is obstructed. For example, if the carriage member 118 is stuck in a position along track 114, the door assembly 101 can be unlocked, allowing the door 104 to slide relative to the carriage member 118, and thus still be able to move to the open or rearmost position. This allows passengers to exit the passenger seat unit 100 when needed and / or even if track 114 fails and the door 104 is in the forward position.

[0046] Furthermore, by including two sliding rails as an option for moving the door 104, the door assembly 101 can comply with various safety regulations, such as FAA Points 19 and 20, which stipulate that the mini suite door must not obstruct any exit path in its open, closed, or sliding position, and that the mini suite door must be able to be opened even in a crowded passageway.

[0047] Door assembly 101 may further include an actuator 122, which can be activated to change the lock state of door assembly 101. Actuator 122 may be a latch, button, handle, motion sensor, or any other suitable device. In some embodiments, actuator 122 may be positioned at any suitable location on at least one of the inner or outer surfaces of door 104. In other embodiments, actuator 122 may be positioned at any suitable location on at least one of the inner or outer surfaces of door 104. Additionally, door assembly 101 may include a plurality of actuators 122, each of which can be activated to change the lock state of door assembly 101.

[0048] In some aspects, actuator 122 may be communicatively coupled to at least a portion of door 104 and / or carriage assembly 118. When actuator 122 is activated, door assembly 101 may change from a locked state to an unlocked state. Consequently, carriage assembly 118 may be released from its fixed connection with door 104, allowing carriage assembly 118 to move along channel 120.

[0049] In some embodiments, the privacy housing 106 may, as needed, include a housing latch that selectively engages the door 104 and holds the door 104 in the rearmost position, such as an impact latch system, latch system, magnetic system, friction-fit system, clip, and / or other suitable means or mechanisms. It should be understood that, depending on the type of housing latch used, the housing latch may include various other and / or additional components as needed. Therefore, the housing latch can be a variety of suitable means or mechanisms for selectively holding the door 104 in the rearmost position. The specific location of the housing latch on the privacy housing 106 and the portion of the door 104 engaged by the housing latch should not be construed as limiting the scope of this disclosure.

[0050] In various embodiments, the passenger seat unit 100 may include various means or mechanisms for selectively securing the door 104 in the foremost position. Such means or mechanisms may, as needed, include, but are not limited to, impact latch systems, latch systems, magnetic systems, friction-fit systems, clips, and / or other suitable means or mechanisms. The means or mechanisms for selectively securing the door 104 in the foremost position may be the same means or mechanisms used for selectively securing the door 104 in the rearmost position.

[0051] In some embodiments, the door 104 of the passenger seat unit 100 may, as needed, include a single-panel door 104, a door 104 having at least a first panel and a second panel, or a door 104 having more than two panels. The multiple panels of the door 104 may be movable relative to each other; for example, the first panel and the second panel may be hinged together so that the first panel can fold toward the second panel.

[0052] According to certain embodiments of the present invention, such as Figures 2A-3B As shown, the carriage component 200 may include a first protrusion 202 and a second protrusion 204. The carriage component 200 can be combined with the above. Figure 1A-1C The carriage component 118 described is the same as or similar to that described above.

[0053] In some embodiments, the first protrusion 202 and / or the second protrusion 204 may be generally T-shaped to enable the carriage component 200 to withstand greater loads. However, the specific shapes of the first protrusion 202 and the second protrusion 204 should not be considered as limiting this disclosure. The first protrusion 202 may extend from the carriage component 200 along a first direction. In some embodiments, the first protrusion 202 may be coupled or engaged with a track 114 to connect the carriage component 200 to the wall portion 102. Thus, the first protrusion 202 may move along the track 114 to allow the carriage component 200 to move along the wall portion 102.

[0054] A second protrusion 204 may extend from the carriage member 200 along a second direction. In some embodiments, the second protrusion 204 may engage or join with the channel 120 to connect the carriage member 200 to the wall portion 102. When the door assembly 101 is locked, the second protrusion 204 is fixed and cannot move along the channel 120. When the door assembly 101 is unlocked, the second protrusion 204 can move along the channel 120 to allow the carriage member 200 to move along the door 104.

[0055] like Figure 3A and 3B As shown, the channel 120 of the door 104 can be shaped to correspond to the shape of the second protrusion 204. For example, the channel 120 can also be T-shaped to accommodate the T-shaped second protrusion 204.
