Description

Technical Field

[0001] The utility model relates to the field of home furnishing manufacturing, in particular to a foldable leisure sleeping chair. Background Art

[0002] The existing Chinese utility model patent with publication number CN210055328U and titled "A Sofa Bed with Linked Retractable Legs" discloses that a first connecting rod is provided in the area above the third hinge of the second leg, the other end of the first connecting rod is hinged to the upper end of the first leg through a fourth hinge, the first leg is hinged to a second connecting rod in the area below the fourth hinge, the other end of the second connecting rod is hinged to the mattress, the mattress is hinged to the guardrail, and the mattress can rotate freely around the hinge. When the sofa bed enters the bed state, the seat cushion and the mattress are linked by the first and second connecting rods, and the seat cushion and the mattress are flipped outward and unfolded. When the sofa bed enters the sofa state, the seat cushion and the mattress are linked by the first and second connecting rods, and the seat cushion and the mattress are flipped inward and retracted. However, when the sofa bed enters the sofa state, only the front side of the seat cushion falls on the sofa seat, which can easily cause the seat cushion and the mattress to sink when used by users, resulting in poor stability.

[0025] like Figure 1-7As shown, a foldable leisure sleeping chair comprises a seat 1, first mounting parts 11 are installed on both sides of the front side of the seat, a folding mechanism 2 is installed on the first mounting part, the folding mechanism comprises a first side rod 21 pivotally connected to the front side of the first mounting part, the first side rod is used to install a first cushion 3, two first cushion cross braces 211 are detachably installed between the two first side rods, the first cushion cross braces can improve the strength of the first side rods, a first limiting pin 212 is installed in the middle of the first side rod, a first limiting surface 111 cooperating with the first limiting pin is provided on the rear side of the first mounting part, the front side of the first side rod is pivotally connected to the first supporting leg 22, and the two A first leg cross brace 221 can be detachably installed between the first supporting legs, and the first leg cross brace can improve the strength of the first supporting leg. The middle part of the first supporting leg is pivotally connected to the first linkage rod 23, and the rear end of the first linkage rod is pivotally connected to the first supporting leg. The front end of the first linkage rod is pivotally connected to the second side rod 24 for installing the second cushion 4. Two second cushion cross braces 241 can be detachably installed between the two second side rods, and the second cushion cross brace can improve the strength of the second side rod. The rear side of the second side rod is connected to the first side rod through a hinge 25, and the hinge includes a first chain plate 251 and a second chain plate 252 that are hinged to each other. The first chain The plate is fixed to the front side of the first side rod, the second chain plate is fixed to the rear side of the second side rod, a second limiting pin 2521 is installed on the second chain plate, the first chain plate is provided with a second limiting surface 2511 matched with the second limiting pin, the second limiting pin contacts the second limiting surface, and the supporting force for the second cushion is improved. In order to optimize the structure, the first supporting leg can be directly pivoted to the rear side of the first chain plate, the front side of the second side rod is pivoted to the second supporting leg 26, and the second leg cross brace 261 can be detachably installed between the two second supporting legs. The second leg cross brace can improve the strength of the second supporting leg, and the top of the second supporting leg is pivoted to the second linkage rod 27. The front end of the linkage rod is pivotally connected to the second supporting leg, the rear end of the second linkage rod is pivotally connected to the first linkage rod, and a backrest mechanism 5 is installed on the rear side of the seat. The backrest mechanism includes a pair of backrest side rods 51 for installing a backrest 6, and two backrest cross braces 52 are installed between the pair of backrest side rods. The backrest cross braces improve the strength of the backrest side rods.

[0026] The specific working process and principle of this utility model:

[0027] When the sitting position is converted into a sleeping position, the second cushion is lifted up to expose the second leg cross brace, and the second leg cross brace can be pulled outward. While the second supporting leg is opened, the second supporting leg drives the second linkage rod, and the second linkage rod drives the first linkage rod. The first linkage rod drives the first supporting leg to open. As the first side rod flips outward, the first and second supporting legs fall to the ground, and the first and second cushions are flush. Then the backrest is pulled, and the bottom of the backrest moves outward along the horizontal guide rail with the roller, and the top of the backrest falls until the backrest is flush with the first and second cushions.

[0028] When the sleeping position is changed to a sitting position, first pull the top of the backrest upwards while pushing the bottom of the backrest inwards. After the backrest is erected to make room, lift the second cushion and rotate the second leg cross brace inwards. While the second supporting leg is retracted, the second supporting leg drives the second linkage rod, and the second linkage rod drives the first linkage rod. The first linkage rod drives the first supporting leg to retract. As the first side rod flips inwards, the second cushion is superimposed on the first cushion. At this time, the first limit pin contacts the first limit surface, blocking the first and second cushions from sinking, and the first and second cushions prevent the backrest from sliding down.

[0029] The utility model has the advantages of convenient operation, stable and reliable structure, and can be placed without leaning against the wall.
