Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a dual-purpose (sitting and reclining) companion chair. Background Technology

[0002] According to the patent document with announcement number CN220734889U, the patent document controls the merging and separation of the load-bearing support frame and the seat support frame through a locking component. The locking component is unlocked and the load-bearing support frame is pulled away from the seat support frame. Finally, the front back panel, the back panel, and the seat panel are aligned in a straight line, and the main body of the companion chair unfolds. During this process, the first rotating frame and the second rotating frame in the middle support frame are rotated and brought closer to each other by the retraction of the pneumatic telescopic rod, so that the first rotating frame and the second rotating frame slowly and smoothly descend and touch the ground.

[0003] The patent document states that the backrest angle cannot be adjusted after the main body of the companion chair is unfolded, which reduces the comfort of the companion when resting. In addition, the companion chair lacks a structure for placing a plate, making it inconvenient for the companion to eat and place items. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-purpose (sitting and reclining) companion chair to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A dual-purpose (sitting and reclining) companion chair includes a first support frame, with support plates fixed to the front and rear sides of the top of the first support frame. A first seat is provided between the two support plates. Insert rods are slidably connected to the front and rear sides of the first seat. Each of the two support plates has several insertion holes for inserting the insert rods. A second seat is hinged to one side of the first seat, and a third seat is hinged to one side of the second seat. A dining board is fixed to the top of the first seat.

[0007] Preferably, the first seat plate has sliding holes on both the front and rear sides that cooperate with the two insert rods, and springs are fixedly connected between the two insert rods and the first seat plate, with the two springs located in the corresponding sliding holes.

[0008] Preferably, the first seat plate and the second seat plate are both hinged together by two connecting plates.

[0009] Preferably, the bottom of the second seat is rotatably connected to a second support frame, and the bottom of the second seat has a storage groove for storing the second support frame.

[0010] Preferably, a third support frame is fixed to the bottom of the third seat, four casters are fixed to the bottom of the third support frame, and a storage basket is fixed inside the third support frame.

[0011] Preferably, two locking plates are rotatably connected to one side of the first support frame, with the two locking plates located on the front and rear sides of the first seat plate respectively, and two locking pins that cooperate with the two locking plates are fixed to one side of the third support frame.

[0012] Preferably, the top of the serving board has a hole for placing a water cup, and the bottom surface of the serving board is tangent to the outer surfaces of the two support plates.

[0013] The advantages compared to existing technologies are as follows: the different holes on the two support plates meet the adjustment needs of the first seat at different angles; the rebound of the two springs pushes the two rods away from each other and inserts them into the corresponding holes, limiting the first seat to the required tilt angle, improving the comfort of the caregiver when resting; the adjusted vertical first seat makes the dining board parallel to the second and third seats, thus facilitating the placement of the caregiver's meals and saving space.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-11 As shown, a dual-purpose (sitting and reclining) companion chair includes a first support frame 1.

[0031] In this embodiment: support plates 2 are fixed on both the front and rear sides of the top of the first support frame 1. A first seat plate 3 is provided between the two support plates 2. Insert rods 7 are slidably connected to both the front and rear sides of the first seat plate 3. Each of the two support plates 2 has several insertion holes for inserting the insertion rods 7. A second seat plate 4 is hinged to one side of the first seat plate 3, and a third seat plate 5 is hinged to one side of the second seat plate 4. A dining board 6 is fixed to the top of the first seat plate 3. The first seat plate 3 is restricted and supported between the two support plates 2 by the two insertion rods 7. The different insertion holes on the two support plates 2 meet the adjustment requirements of the first seat plate 3 at different angles. The connection of the first seat plate 3, the second seat plate 4 and the third seat plate 5 supports the caregiver. After adjustment, the vertical first seat plate 3 makes the dining board 6 parallel to the second seat plate 4 and the third seat plate 5, so as to place the caregiver's food.

[0032] In this embodiment: sliding holes are provided on both the front and rear sides of the first seat plate 3 to cooperate with the two insertion rods 7. Springs 8 are fixedly connected between the two insertion rods 7 and the first seat plate 3. The two springs 8 are respectively located in the corresponding sliding holes. By pressing the two insertion rods 7 to slide closer to each other in the corresponding sliding holes, the two springs 8 are compressed, causing the two insertion rods 7 to disengage from the corresponding insertion holes, thus releasing the limitation on the tilt angle of the first seat plate 3. The rebound of the two springs 8 pushes the two insertion rods 7 away from each other and inserts them into the corresponding insertion holes, thus limiting the first seat plate 3 to the required tilt angle.

[0033] In this embodiment: the first seat plate 3 and the second seat plate 4 are both hinged together by two connecting plates 9, and the first seat plate 3, the second seat plate 4 and the third seat plate 5 are connected by four connecting plates 9.

[0034] In this embodiment: the bottom of the second seat plate 4 is rotatably connected to the second support frame 10. The bottom of the second seat plate 4 is provided with a storage slot for storing the second support frame 10. The second support frame 10 supports the second seat plate 4 while preventing the first seat plate 3 and the second seat plate 4 from making too much noise when unfolded and falling. The second support frame 10 in the folded state of the second seat plate 4 is placed in the storage slot.

[0035] In this embodiment: a third support frame 11 is fixed to the bottom of the third seat 5, four casters 13 are fixed to the bottom of the third support frame 11, and a storage basket 12 is fixed inside the third support frame 11. The third support frame 11 supports the third seat 5, and the four casters 13 drive the third support frame 11 and the third seat 5 to move. The storage basket 12 is used to place the caregiver's items.

[0036] In this embodiment: two locking plates 14 are rotatably connected to one side of the first support frame 1. The two locking plates 14 are located on the front and rear sides of the first seat plate 3 respectively. Two locking pins 15 that cooperate with the two locking plates 14 are fixed on one side of the third support frame 11. By rotating the two locking plates 14 inward, the two locking plates 14 fall on the corresponding two locking pins 15, thus restricting the movement of the third support frame 11.

[0037] In this embodiment: the top of the table board 6 is provided with a placement hole for placing a water cup, and the bottom surface of the table board 6 is tangent to the outer surfaces of the two support plates 2. The water cup of the caregiver is placed through the placement hole of the table board 6 to prevent the water cup from falling over.

[0038] Working principle: When the companion chair is needed for rest, the two locking plates 14 are rotated outward, thereby disengaging the two locking plates 14 from the corresponding two locking pins 15, releasing the restriction on the third support frame 11. The third support frame 11 is pulled to one side, and the third support frame 11 drives the four casters 13 and the third seat 5 to move to one side. When the third seat 5 moves to one side, it drives the first seat 3 and the second seat 4 to move and unfold to one side through the four connecting plates 9 respectively. The two insert rods 7 rotate in the two insert holes at the bottom of the two support plates 2. During this process, the second support frame 10 rotates out from the placement groove at the bottom of the second seat 4 and the second support frame 10 contacts the ground.

[0039] When it is necessary to adjust the tilt angle of the first seat plate 3, press the two insert rods 7 and slide them closer to each other in the corresponding sliding holes. The two springs 8 are compressed, causing the two insert rods 7 to disengage from the two bottom holes of the two support plates 2, thus releasing the limitation on the tilt angle of the first seat plate 3. Rotate the first seat plate 3 with its bottom as the pivot to the required tilt angle. Stop pressing the two springs 8. The rebound of the two springs 8 pushes the two insert rods 7 away from each other and inserts them into the two corresponding holes, thus limiting the first seat plate 3 to the required tilt angle.

[0040] When the dining board 6 is needed, press the two insert rods 7 to release the limitation on the tilt angle of the first seat 3, rotate the first seat 3 to a vertical position with its bottom as the pivot, and stop pressing the two springs 8. The rebound of the two springs 8 pushes the two insert rods 7 away from each other and inserts them into the two top holes of the two support plates 2.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
