Technical Field

[0001] This utility model relates to the technical field of seating, specifically a double chair for meetings. Background Technology

[0002] As office environments become more multifunctional and compact, scenarios such as meetings, training sessions, and collaborative work place higher demands on the number of seats and space configuration. Especially during crowded meetings, it is often necessary to temporarily add a large number of seats to accommodate multiple people at the same time.

[0003] Currently, widely used office chairs typically include a seat cushion, backrest, and support structure. Some chairs also feature armrests and wheels to enhance comfort and ease of movement. Most existing office chairs employ a fixed design, with the seat cushion and backrest secured by brackets or connectors. The backrest is generally adjustable in tilt angle, but the overall structure is designed for single-person seating. In addition, some chairs are foldable or stackable for easy storage and transport, but their primary use remains as individual seats.

[0004] In the existing technology, most office chairs are single-person structures. During meetings or training sessions, a large number of chairs need to be placed to provide enough seating, resulting in a large space occupation and affecting the space utilization rate of the meeting room. Utility Model Content

[0005] The purpose of this invention is to provide a double chair for meetings, in order to solve the problem that a large number of chairs need to be placed to provide a sufficient number of seats during meetings or training sessions, resulting in a large space occupation and affecting the space utilization rate of the meeting room.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a double chair for meetings, including a seat cushion and a backrest, one side of the backrest being rotatably connected to the seat cushion via a hinge, the backrest being able to flip up to be parallel to the seat cushion, for expanding the usable area of ​​the chair to allow two people to sit at the same time; the backrest is provided with a mounting groove on the rear side, and a central support plate for supporting the backrest is hinged in the mounting groove; the backrest is also provided with two storage slots, and side support plates are hinged in the storage slots respectively, for supporting the structural stability of the backrest after flipping up.

[0007] Preferably, two positioning grooves are respectively opened on both sides of the seat cushion, and a swing column is hinged inside the positioning groove. Two placement plates are provided on the top of the seat cushion, and the bottom surface of the placement plate is fixed to the top of the swing column.

[0008] Preferably, a rotating hole is provided on one side of the backrest, a rotating shaft is inserted into the rotating hole, T-shaped plates are fixed at both ends of the rotating shaft, and a T-shaped groove is provided on the top surface of the placement plate, with the T-shaped plate and the T-shaped groove slidingly engaged.

[0009] Preferably, the seat cushion is provided with detachable storage boxes on both sides, and a limiting groove is provided on both sides of the seat cushion. A limiting plate is fixed on the surface of the storage box, and the limiting groove and the limiting plate are slidably engaged.

[0010] Preferably, each of the four corners of the bottom surface of the seat cushion is fixed with a support leg, and a reinforcing rod is fixed to the surface of the support leg, with the other end of the reinforcing rod fixed to the bottom surface of the seat cushion.

[0011] Preferably, the top surface of the seat cushion and the front side of the backrest are respectively provided with flexible pads.

[0012] Compared with existing technologies, a double chair for meetings that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] 1. By flattening the backrest, the backrest and seat cushion are placed on the same horizontal plane. The backrest is supported on the ground by the central support plate and side support plates, which realizes the quick conversion between single and double seats. The number of seats can be flexibly adjusted according to the actual meeting needs, effectively reducing the number of seats and significantly improving the utilization rate of meeting room space.

[0014] 2. When the seat is used as a single seat, the placement board is above the seat cushion, and the T-shaped board is slidably inserted into the T-shaped groove, which locks the seat cushion and backrest at the current angle, making it convenient to use as a single seat. Before changing the angle between the seat cushion and backrest, the staff will first rotate the T-shaped board clockwise around the rotation axis to disengage the T-shaped board from the T-shaped groove, and then rotate the swing column clockwise to move the placement board under the seat cushion to avoid obstructing the user from sitting down.

[0015] Third, the user's personal items such as water cups will be placed inside the storage box for the user's convenience. When not in use, the user can also apply an upward force to the storage box to move the limiting plate out of the limiting groove, thereby increasing the convenience of use.

Detailed Implementation

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, a double chair for meetings includes a seat cushion 1 and a backrest 2. One side of the backrest 2 is rotatably connected to the seat cushion 1 via a hinge. The backrest 2 can be flipped to be parallel to the seat cushion 1 to expand the usable area of ​​the chair for two people to sit at the same time. The backrest 2 has a mounting groove 3 on its rear side, and a central support plate 4 for supporting the backrest 2 is hinged in the mounting groove 3. The backrest 2 also has two storage slots 5 on its rear side, and side support plates 6 are hinged in the storage slots 5 to support the structural stability of the backrest 2 after it is flipped. Support legs 14 are fixed at the four corners of the bottom surface of the seat cushion 1. Reinforcing rods 15 are fixed to the surface of the support legs 14, and the other end of the reinforcing rods 15 is fixed to the bottom surface of the seat cushion 1. Flexible pads 16 are respectively provided on the top surface of the seat cushion 1 and the front side of the backrest 2. The flexible pads 16 are made of mesh and filled with polyurethane foam.

[0023] When the seat needs to be switched from single-person mode to double-person mode during use, the operator first rotates the rotating shaft 11 located on the side of the backrest 2 clockwise, so that the T-shaped plates 12 at both ends of the rotating shaft 11 disengage from the sliding engagement with the T-shaped groove 13 at the top of the placement plate 9. At this time, the locking state between the seat cushion 1 and the backrest 2 is released.

[0024] Subsequently, the staff rotated the swing columns 8 located on both sides of the seat cushion 1 clockwise. The swing columns 8 caused the placement plate 9 to flip downwards and under the seat cushion 1, preventing the placement plate 9 from obstructing the user from sitting down normally. After the placement plate 9 was moved, the backrest 2 was rotated around the hinge to make the backrest 2 and the seat cushion 1 at the same horizontal plane.

[0025] After completing the above steps, the staff flips the central support plate 4 in the installation slot 3 and the two side support plates 6 in the storage slot 5 from the back of the backrest 2 in turn, so that the central support plate 4 and the side support plates 6 are in contact with the ground and supported under the backrest 2, ensuring that the backrest 2 is in a stable support state.

[0026] like Figure 2 and Figure 3 As shown, two positioning grooves 7 are respectively opened on both sides of the seat cushion 1. A swing column 8 is hinged inside the positioning groove 7. Two placement plates 9 are set on the top of the seat cushion 1. The bottom surface of the placement plate 9 is fixed to the top of the swing column 8. A rotating hole 10 is opened on one side of the backrest 2. A rotating shaft 11 is inserted into the rotating hole 10. T-shaped plates 12 are fixed at both ends of the rotating shaft 11. A T-shaped groove 13 is opened on the top surface of the placement plate 9. The T-shaped plate 12 and the T-shaped groove 13 slide together.

[0027] In use, in the two-person mode, the backrest 2 can serve as an additional seating area for a second user. The support leg 14 and the reinforcing bar 15 together support the entire seat structure, ensuring the overall safety and stability of the seat.

[0028] In single-person mode, the placement board 9 is positioned above the seat cushion 1 and is locked by inserting the T-shaped plate 12 into the T-shaped groove 13 to prevent the seat cushion 1 and backrest 2 from becoming loose, making it convenient to use as a single seat.

[0029] like Figure 2 As shown, the cushion 1 has detachable placement boxes 17 on both sides. Each side of the cushion 1 has a limiting groove 18. A limiting plate 19 is fixed to the surface of the placement box 17. The limiting groove 18 and the limiting plate 19 slide together.

[0030] When it is necessary to temporarily store a water cup or personal items, the storage box 17 can be slidably installed in the limiting grooves 18 on both sides of the seat cushion 1 to increase the temporary storage space; when not in use, the storage box 17 can be disassembled by applying an upward force, which will cause the limiting plate 19 to disengage from the limiting groove 18, thus improving the flexibility of use.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
