[0057] The present invention is described below based on the embodiments shown in the accompanying drawings. The embodiments disclosed this time can be considered to be illustrative in all aspects and not restrictive. The scope of the present invention is not limited by the description of the following embodiments, but is only shown by the scope of the claims, and includes all modifications with the same meaning as the scope of the claims and within the scope of the claims.

[0058] The structure of a folding table and chair mechanism suitable for use in a narrow cabin of the present invention is described below in conjunction with specific embodiments.

[0059] like Figure 1 , Figure 4 and Figure 6 The front view, left view and three-dimensional structure schematic diagram of an embodiment of a folding table and chair mechanism suitable for use in a narrow cabin of the present invention are shown, including a folding dining table assembly 1 and a folding dining chair assembly 2, wherein the folding dining table assembly 1 and the folding dining chair assembly 2 are arranged side by side. Figure 2 and Figure 7 As shown, the folding dining table assembly 1 of this embodiment includes a first mounting base 3 and a rectangular table board 4 arranged vertically, and the first mounting base 3 is mounted on the side wall. The left side of the first mounting base 3 is aligned with the right side of the folding dining chair assembly 2. A rectangular opening groove 5 is arranged on the front surface of the first mounting base 3, and two vertical slide rails 6 are installed on the left and right side walls of the opening groove 5. The left and right parts of the rear end of the table board 4 are installed with hinge seats, and the two hinge seats and two sliders 7 are rotatably hinged together through shafts 17. The two sliders 7 can be installed on the two slide rails 6 to slide up and down, and the sliders 7 and the slide rails 6 can be concave-convex matching structures. The table board 4 can move up and down along the slide rails 6 through the two sliders 7, so as to achieve flipping. The left and right sides of the middle part of the lower surface of the table board 4 are rotatably connected to the first mounting base 3 by hinged connection. The reason why this embodiment adopts a slide rail 6, a support rod 7 and a support assembly 8 arranged on the left and right sides of the table board 4 is to maintain the support stability of the overall folding table and chair mechanism.

[0060] refer to Figure 7 As shown, the support assembly 8 includes a support rod 9 and a buffer support portion. The front ends of the two support rods 9 of the two support assemblies 8 are rotatably connected to the left and right ends of the first hinge seat 11 connected to the bottom surface of the table board 4 through a pin shaft, and the rear ends of the two support rods 9 are rotatably connected to the two second hinge seats 12 connected to the lower part of the left and right parts of the opening groove 5 through two pin shafts. The buffer support portion of this embodiment adopts a gas spring support 10, and the front end of the gas spring support 10 is rotatably connected to the hinge seat set on the support rod 9 through a pin shaft, and the connection part is located on the support rod 9 near the front end. The rear end of the gas spring support 10 is rotatably connected to the hinge seat set at the rear part of the lower surface of the table board 4 through a pin shaft. The gas spring support 10 has a certain damping, and has a buffering function when the table board 4 is unfolded and folded into place to avoid collision. When used, it can slow down the unfolding and folding process to ensure safe operation.

[0061] When the slider 7 slides upward along the slide rail 6, it can drive the table top 4 to rotate from the horizontal direction to the vertical direction, fit into the opening groove 5, and keep the table top 4 fixed in the vertical direction by locking the folding lock 13. The folding lock 13 of this embodiment adopts a linkage structure of a lock tongue 15 controlled by a button 14. The button 14 is located below the opening groove 5 on the front surface of the first mounting base 3. The lock tongue 15 can extend upward from the bottom of the opening groove 5 under the control of the button 14. A groove is provided on the lower surface of the table top 4 when it is in a vertical position (not shown in the figure). When the table top 4 is in a vertical position, pressing the button 14 can make the lock tongue 15 extend upward into the groove of the table top 4, so that the table top 4 is locked and fixed in the vertical position. When the button 14 is pressed again, the lock tongue 15 can be disengaged from the groove of the table top 4, and the table top 4 can slide downward along the slide rail 6 along with the slider 7, driving the table top 4 to rotate from the vertical direction to the horizontal direction, and be basically perpendicular to the first mounting base 3. At this time, the table top 4 can be kept fixed in the horizontal direction by locking the deployment lock 16. In this embodiment, the deployment lock 16 can be rotatably installed at the rear position under the table top 4. The deployment lock 16 can be rotated to hook the shaft 17, so that the two sliders 7 cannot slide along the two slide rails 6.

[0063] (1) Press the button 14 of the lock 13 to disengage the lock tongue 15 from the groove of the table top 4, so that the table top 4 pops out of the opening slot 5;

[0064] (2) The table top 4 slides down slowly along the slide rail 6 with the slide 7 under the action of gravity and the slide 7;

[0065] (3) Manually flip the table top 4 upward to a horizontal position. When the unfolding lock 16 is hooked with the shaft 17, it is automatically locked. At this time, the table top 4 is fully unfolded and in a horizontal position. After unfolding, the table top load-bearing capacity is not less than 20 kg.

[0066] The folding operation steps of the folding dining table assembly 1 of the present invention are as follows:

[0067] (1) Pull the deployment lock 16 to disengage it from the shaft 17 and unlock the table top 4;

[0068] (2) Press the front end of the table top 4 downward and push the table top 4 backward. When the table top 4 completely enters the opening groove 5 on the first mounting base 3, the folding lock 13 can be automatically locked.

[0069] Combination Figure 3-Figure 5 and Fig. 9As shown, the folding dining chair assembly 2 includes a second mounting base 18 parallel to and aligned with the first mounting base 3, and a first-level folding chair 19 and a second-level folding chair 20. A storage hole 21 is provided in the middle and upper part of the second mounting base 18, and the shape of the storage hole 21 is adapted to the shape of the first-level folding chair 19 and the second-level folding chair 20 when they are folded and rotated to a vertical position. The cross-section of the storage hole 21 in this embodiment is composed of a rectangular structure located at the upper part, a rectangular structure located at the lower part, and an arc transition structure located between the two. The distance between the left and right sides of the rectangular structure located at the lower part is greater than the distance between the left and right sides of the upper rectangular structure. The first-level folding chair 19 is rotatably connected to the bottom of the rectangular structure hole at the lower part, and the first-level folding chair 19 and the second-level folding chair 20 can be rotated into the storage hole 21 after being folded.

[0070] The secondary folding chair 20 is rotatably connected to the front end of the primary folding chair 19 .

[0071] Specifically, the first-level folding chair 19 includes a first-level seat base 22 rotatably connected to the bottom of the storage hole 21, which is arranged horizontally. The first-level seat base 22 is rotatably connected to the bottom of the storage hole 21 through a first-level flip hinge 23, and is located in the storage hole 21 after flipping 90 degrees. The front end of the bottom of the first-level seat base 22 is rotatably connected to a first-level leg 24 through a hinged manner, and the lower end of the first-level leg 24 is against the ground. A foldable first-level rotating chair 25 is installed on the upper surface of the first-level seat base 22, and the first-level rotating chair 25 includes a first-level seat plate 27 rotatably installed on the first-level seat base 22 through a turntable 26, and the first-level seat plate 27 is rotatably connected to the first-level backrest 29 through a backrest flip hinge 28, and the direction of the first-level rotating chair 25 is limited by a first-level limiter, and the first-level limiter of this embodiment adopts a spring limiter pin. The first-level backrest 29 can be folded onto the first-level seat plate 27. A primary leg pull rod 31 is rotatably connected between the primary leg 24 and the second mounting base 18 in an articulated manner.

[0072] The secondary folding chair 20 includes a secondary seat base 32, which is arranged horizontally. The secondary seat base 32 is rotatably connected to the front end of the primary seat base 22 through a secondary flip hinge 33, and the bottom front end of the secondary seat base 32 is rotatably connected to a secondary leg 34 through an articulated manner, and the lower end of the secondary leg 34 is against the ground. A foldable secondary rotating chair 35 is installed on the upper surface of the secondary seat base 32. The secondary rotating chair 35 of this embodiment has the same structure as the primary rotating chair 25. The secondary rotating chair 35 includes a secondary seat plate 37 rotatably installed on the secondary seat base 32 through a turntable 36, and the secondary seat plate 37 is rotatably connected to the secondary backrest 39 through a backrest flip hinge 38, and the direction of the secondary rotating chair 35 is limited by a secondary limiting member, and the secondary limiting member of this embodiment adopts a spring limiting pin 40. The secondary leg 34 is rotatably connected to the secondary seat base 32 through an articulated manner to a secondary leg pull rod 41.

[0073] A primary handle 42 is provided at the front end of the primary seat base 22. A secondary handle 43 is provided at the front end of the secondary seat base 32.

[0074] refer to Figure 4 As shown, in order to fold and fix the primary folding chair 19 and the secondary folding chair 20 in the storage hole 21, a twist lock 44 is installed on the front surface of the second mounting base 18 above the storage hole 21. When the folding chair is in the storage hole 21, the folding chair can be fixed in the storage hole 21 by rotating the twist lock 44. In order to prevent the primary folding chair 19 and the secondary folding chair 20 from turning down too quickly when turning outward as a whole after unlocking the twist lock 44, an assisting gas spring 45 is installed on the second mounting base 18 between the upper position of the storage hole 21 and the primary flip hinge 23 to prevent the whole from turning down too quickly.

[0075] refer to Fig.10 , Fig.11 As shown, it can be seen from the motion relationship that when the first-level folding chair 19 is opened, the first-level leg pull rod 31 drives the first-level leg 24 to open synchronously; when the second-level folding chair 20 is opened, the second-level leg pull rod 41 drives the second-level leg 34 to open synchronously. When operating, it is only necessary to pull the first-level folding chair 19 and the second-level folding chair 20 through the first-level handle 42 and the second-level handle 43 respectively to achieve rapid and complete opening. The unfolding and folding operations are simple and reliable. The first-level swivel chair 25 and the second-level swivel chair 35 can respectively achieve 180° rotation through the turntables 26 and 36 at the bottom, and the seat direction can be limited by the spring limit pin and the spring limit pin 40. The first-level backrest 29 and the second-level backrest 39 adopt a foldable solution, which can achieve complete folding of the double folding swivel chair.

[0076] The first-stage seat base 22 and the first-stage supporting legs 24, and the second-stage seat base 32 and the second-stage supporting legs 34 of the present invention are all linked structures. When the first-stage seat base 22 and the second-stage seat base 32 are flipped inward, the first-stage supporting legs 24 and the second-stage supporting legs 34 are retracted accordingly.

[0077] Combination Fig.10 As shown, the unfolding operation steps of the folding dining chair assembly 2 of the present invention are:

[0078] (1) Turn the twist lock 44 to unlock, pull the primary handle 42, and flip the primary folding chair 19 and the secondary folding chair 20 outward as a whole (the auxiliary gas spring 43 is configured to prevent the whole from flipping down too quickly);

[0079] (2) Under the linkage action of the first-stage leg pull rod 31, the first-stage leg 24 is automatically opened, and when the first-stage seat base 22 reaches the horizontal position, the first-stage flip is completed;

[0080] (3) Pull the secondary handle 41 to flip the secondary folding chair 20 outward as a whole;

[0081] (4) During the flipping process, the secondary leg pull rod 41 drives the secondary leg 34 to open synchronously. When the secondary seat base 32 opens to a horizontal state and the secondary leg 34 is fully opened and touches the ground, the secondary flipping is completed.

[0082] (5) Manually flipping the primary backrest 29 and the secondary backrest 39 upward to the fully open position (about 100 degrees) can complete the deployment operation of the primary swivel chair 25 and the secondary swivel chair 35; since the primary swivel chair 25 and the secondary swivel chair 35 can rotate 180 degrees, the posture adjustment of the seat in the same direction can be achieved.

[0083] When the folding dining chair assembly 2 of the present invention is folded, the first-level backrest 29 and the second-level backrest 39 are first folded onto the first-level seat plate 27 and the second-level seat plate 37 respectively. Since the first-level swivel chair 25 and the second-level swivel chair 35 are respectively installed on the first-level seat base 22 and the second-level seat base 32, the second-level folding chair 20 is folded onto the first-level folding chair 19 by flipping the second-level flip hinge 33, and then the first-level folding chair 19 and the second-level folding chair 20 are flipped as a whole into the storage hole 21 by flipping the first-level flip hinge 23.

[0084] The present invention provides a folding table and chair mechanism suitable for use in a small cabin, which can be completely folded and folded to achieve space clearance, and can be used for other activities such as sports and accommodation; and after unfolding, it can achieve support functions such as dining and learning, and is suitable for a small space environment. Both the folding dining table assembly 1 and the folding dining chair assembly 2 adopt a linkage mechanism, which is simple to operate and convenient for rapid unfolding and folding in a small space environment. By folding the folding dining table assembly 1 and independently unfolding the folding dining chair assembly 2, the conference support function can be realized, and by rotating the folding dining chair assembly 2, the orientation of the personnel can be changed, which is convenient for activities such as watching movies. The folding table and chair mechanisms of the present invention all adopt a purely mechanical structure, are manually operated, and have high system reliability. The parameter dimensions and backrest tilt design of the folding table and chair mechanism of the present invention provide good ergonomics when a person is in a sitting position. The folding dining table assembly 1 and the folding dining chair assembly 2 adopt a modular design, and the number of dining tables and dining chairs can be freely combined according to the number of people. According to space limitations, the double table and chairs can be replaced with single tables and chairs, that is, the length of the table top and the slide rail of the dining table is reduced, and the dining chair adopts a first-level folding and cancels the second-level folding. The folding table and chair mechanism can be used in combination to convert the space application scene.

[0085] The above-mentioned embodiments are only descriptions of the preferred implementation methods of the present invention, and are not intended to limit the scope of the present invention.
