Description

Technical Field

[0001] This invention relates to the field of aircraft equipment technology, specifically to a portable follow-fly seat. Background Technology

[0002] Transport aircraft should meet the requirements of various operating conditions, such as passenger and cargo transport. These aircraft should be equipped with portable seats that can be quickly removed and easily stored when transporting cargo, in order to meet the requirements of passengers riding on board.

[0003] Currently, some quick-release mechanisms are available to remove seats from the aircraft floor, but most of these mechanisms use threaded connections for installation. This method is relatively slow to install and remove, and requires tools such as wrenches and screwdrivers. Installation and removal are time-consuming and laborious, and a certain amount of operating space must be left for wrenches and other tools, which cannot meet the requirements for installation in confined spaces. Summary of the Invention

[0004] The purpose of this invention is to provide a portable seat with quick installation and removal, retractable backrest, and folding function, which can enable a single person to complete the installation or removal of the seat within 10 seconds without operating tools, so as to meet the requirements of rapid installation, disassembly and use in aircraft, and also meet the requirements of saving space.

[0005] Invention technical solution: A portable flight seat, including a quick-release mechanism, a backrest telescopic mechanism, a seat folding mechanism, a seat leg column, and a ground connector. One end of the seat leg column is connected to the quick-release mechanism, and the other end is connected to the backrest telescopic mechanism. The seat folding mechanism is also provided on the seat leg column. The quick-release mechanism includes a pin, a top ball, and a locking pin. The locking pin is fixedly connected to the pin, and the top ball is fixedly installed in the ground connector. The ground connector is installed on the aircraft floor. One end of the seat leg column has a radial through hole. The pin is provided with a left recess and a right recess. After the pin is inserted into the through hole of the seat leg column, the top ball is located in the left recess for quick-release locking and in the right recess for quick-release unlocking.

[0006] In the above scheme, the ground connector is a hollow cylindrical open shape, which is adapted to the shape of the chair leg upright. A locking hole is provided on the side. The locking pin is L-shaped, and its "L" end corresponds to the locking hole. The chair leg upright and the ground connector are vertically inserted. After the pin shaft is radially inserted into the through hole, the top ball is located in the left recess. The "L" end of the locking pin is inserted into the locking hole to achieve quick locking. The "L" end of the locking pin located in the right recess is disengaged from the locking hole to achieve quick unlocking.

[0007] In the above scheme, the backrest telescopic mechanism includes a backrest tube and a second locking pin. The backrest tube is telescopically connected to the chair leg upright, and the locking pin locks the backrest tube and the chair leg upright in a suitable position.

[0008] In the above scheme, the backrest extension mechanism also includes a knob, and the locking pin two is fixedly connected to the knob. Pulling the knob can drive the locking pin two out, and the pin head of the locking pin two disengages from the backrest tube to unlock it.

[0009] In the above scheme, the backrest telescopic mechanism also includes an end cover with a waist-shaped hole. The knob passes through the end cover and is fixedly connected to the second locking pin. Rotating the end cover causes the knob to enter the waist-shaped hole of the end cover, and the second locking pin enters the backrest tube to lock. When the knob is flush with the end face of the end cover, the second locking pin disengages from the backrest tube to unlock.

[0010] In the above scheme, a compression spring is provided in the backrest tube, and the compression spring is sleeved in the locking pin two. When the knob is rotated 90°, the compression spring in the backrest tube is released.

[0011] In the above solution, the seat folding mechanism includes a rigid seat frame and a foldable fabric strap. The two ends of the rigid seat frame are connected to the chair leg posts through pivots, so that the rigid seat frame can be folded until it is parallel to the chair leg posts.

[0012] In the above solution, the seat folding mechanism also includes a seat frame tube joint for folding the rigid seat frame upward.

[0013] The advantages and beneficial effects of this invention are as follows: Because the lower end of the invention connects to the aircraft floor via a ground connector, which is flush with the aircraft floor surface and has no protrusions, it effectively prevents passengers from tripping. The two seat legs are connected to the ground connector via a quick-release mechanism, allowing for quick and easy assembly and disassembly within 10 seconds without tools, making operation convenient and quick, and requiring minimal operating space. This quick-release mechanism has high strength, ensuring the safety of the seat. The backrest extension mechanism can be rotated and locked, allowing one side of the backrest extension mechanism to be unlocked first, followed by the other side, and then the backrest extension operation can be performed while the other side is unlocked. This mechanism facilitates single-person operation and improves operational convenience. After the invention allows for quick removal from the floor, seat folding, and backrest retraction, the seat occupies little space and can be easily placed in an aircraft storage case, effectively saving storage space and meeting the needs of frequent assembly and disassembly in small spaces. This invention has a simple structure, is easy to install, easy to maintain, highly reliable, and easy to promote and use. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described in detail below through specific embodiments:

[0022] like Figure 1 The diagram shows the portable flight seat of this invention, including a quick-assembly / disassembly mechanism 1, a backrest extension mechanism 2, and a seat folding mechanism 3. These three mechanisms work together to achieve quick assembly / disassembly and easy storage of the seat. The quick-assembly / disassembly mechanism has good stability and can achieve rapid disassembly within 10 seconds without the need for tools.

[0023] like Figure 2-3The diagram shows a quick-assembly and quick-disassembly mechanism of the present invention. The quick-assembly and quick-disassembly mechanism 1 includes a pin 101, a top ball 102, a ground connector 103, a locking pin 104, a chair leg column 105, and a top ball support 106. The pin 101 passes through the chair leg column 105, and the locking pin 104 is fixedly connected to the pin 101. The top ball 102 is fixed in the top ball support 106, which is fixedly connected to the chair leg column 105. Therefore, the relative position of the top ball 102 and the chair leg column 105 remains unchanged. A compression spring is embedded inside the top ball 102. When the pin 101 is pushed radially along the chair leg column 105, the top ball 102 can slide and enter the recess 101a of the pin 101. When the top ball 102 enters the left recess 101a, the locking pin 104 disengages from the locking hole 103a on the side of the ground connector 103, thus being in the unlocked state. When the top ball 102 enters the right recess 101b, the locking pin 104 enters the locking hole 103a on the side of the ground connector 103, thus being in the locked state. The relative position of the locking pin 104 and the locking hole 103a on the side of the ground connector is controlled by the change in the position of the top ball 102. When the top ball 102 is in the left recess 101a of the pin 101, the locking pin 104 disengages from the locking hole 103a on the side of the ground connector, thus being in the unlocked state; when the top ball 102 is in the right recess 101b of the pin 101, the locking pin 104 enters the locking hole 103a on the side of the ground connector, thus being in the locked state. The quick-installation and quick-removal mechanism 1 is located at the bottom of the seat leg. The seat can be removed and installed by unlocking and locking the locking pin. The unlocking operation is convenient, and the locking operation is stable. The top ball can be pulled into one of the two recesses on the pin. When the top ball enters the right recess, the locking pin enters the locking hole on the side of the ground connector, enabling quick installation of the seat and the aircraft plate interface. When the top ball enters the left recess, the locking pin disengages from the locking hole on the side of the ground connector, unlocking the seat. After both uprights on both sides of the seat are unlocked, the seat can be quickly removed.

[0024] like Figure 4-5 The diagram shows a schematic of the backrest telescopic mechanism of the present invention. The backrest telescopic mechanism includes a backrest tube 201, a knob 202, a locking pin 203, and an end cap 204. The backrest telescopic mechanism enables the backrest tube to extend and retract within the column. When extended, the backrest height meets ergonomic requirements, ensuring seating comfort; when retracted, it effectively saves storage space.

[0025] Locking pin 203 is fixedly connected to knob 202. Pulling knob 202 pulls out locking pin 203, causing its head to disengage from backrest tube 201 and unlock. End cap 204 has a slotted hole. When knob 204 is pulled out, rotating end cap 204 approximately 90° makes the knob flush with the end face of the end cap. At this time, the compression springs in end cap 204 and backrest tube 201 are compressed, and the locking pin is unlocked. Rotating knob 204 90° releases the compression springs in end cap and backrest tube 201, allowing knob 204 to enter the slotted hole in end cap, and the locking pin enters backrest tube 201 to lock.

[0026] By aligning the control knob 204 with the waist-shaped hole on the end cover, the backrest extension mechanism on one side of the seat can be unlocked independently first, and then the backrest extension mechanism on the other side can be unlocked. The backrest extension operation can be performed when both sides are unlocked, enabling single-person operation and improving ease of operation.

[0027] When in operation, pull out locking pin 203 and rotate the knob 90° to disengage locking pin 203 from the locking hole of the backrest tube. At this time, the backrest tube can be pulled out to realize the backrest extension function. When the knob is rotated 90° again and the backrest tube is gently pulled out, the locking pin will fall into the locking hole of the backrest tube to realize locking.

[0028] The seat folding mechanism includes a seat frame and a seat frame connector. The seat frame can be folded up 90° to be flush with the backrest. When seated, the seat frame unfolds to a horizontal position for easy seating. The seat frame of the seat folding mechanism 3 can be folded up around the tube connector to achieve folding. When unfolded, it is convenient for seating; when folded, it effectively saves aisle and storage space.

[0029] Ground connector 103 should be installed on the aircraft floor in advance.

[0030] like Figure 6 The diagram shows the unfolding and folding of the seat frame of the present invention. When the seat frame is unfolded, it is convenient for passengers to sit on it. Folding it up makes it easier to make room for the aisle, allowing passengers to enter and exit the aisle. Folding it up also saves storage space.

[0031] The above technical solutions are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent changes made in accordance with the scope of this application shall still fall within the protection scope of this application.
