Description

Technical Field

[0001] The utility model belongs to the technical field of sofas, in particular to a segmented folding sofa chair. Background Art

[0002] A sofa is a cushioned chair with a backrest. To facilitate transportation and installation, it is now mostly foldable. Some sofas can also meet the needs of both seating and sleeping.

[0003] On the other hand, the existing reclining sofa chair mainly includes a seat plate, armrests are provided on both sides of the seat plate, a back cushion is rotatably provided on the back of the seat plate, and a leg rest is usually rotatably provided at the front end of the seat plate so that the sitting posture can be maintained under normal circumstances. When lying down, the seat plate and leg rest are rotated and unfolded, so that the sofa chair can be used for lying flat.

[0004] For example, a Chinese utility model patent with patent publication number CN204292664U and publication date 2015.04.29 discloses a folding sofa bed, the structure of which includes a seat cushion, armrest frames supported on both sides of the seat cushion, and a backrest fixedly connected to the armrest frames, a receiving cavity is formed between the seat cushion and the two armrest frames, the backrest includes a main back body and an auxiliary back body, the main back body can rotate around the auxiliary back body and be spliced ​​with the seat cushion, an additional part that can slide and be spliced ​​with the seat cushion is placed in the receiving cavity, the additional part includes a lifting platform and an additional pad, the additional pad is placed on the lifting platform, a slide groove that can accommodate a sliding protrusion is fixedly connected to the armrest frame, and the additional pad, seat cushion and main back body are connected in sequence.

[0005] The folding sofa bed in this utility model patent has the following general structural principles: the sofa bed is in a bed state by first pulling the handle to drive the entire attachment to slide horizontally outward, and the attachment cushion slides outward with the help of the lifting platform and the rolling of the rollers. The lifting platform is powered on and the height of the lifting platform is adjusted. By raising the lifting platform, the attachment cushion is aligned with the height of the seat cushion. The main back body is then flipped downward until it contacts the limit support member integrally provided on the auxiliary back body. The telescopic rod in the storage slot is pulled out so that the telescopic rod is perpendicular to the ground and supports the main back body. At this time, the main back body, seat cushion, and attachment cushion surface form the same plane. When the sofa bed is converted from a bed state to a sofa, the lifting platform needs to be adjusted to be lowered below the bottom surface of the seat cushion. The pulling handle is then pushed to slide the attachment cushion toward the backrest so that the attachment cushion contacts the backrest. At this time, the seat cushion is ready for people to sit on.

[0006] However, the folding sofa bed still has at least the following deficiencies during actual use, which are, in other words, the technical problems to be solved by the present utility model.

[0007] The additional pad structure is made flush with the seat cushion by lifting it up on a lifting platform, so a lifting platform as an electrified facility must be used. Therefore, there are obvious disadvantages such as complex operation, high cost, and high failure rate.

[0008] Therefore, in summary, there is an urgent need for a new sofa chair that has a folding structure that can be simpler, more efficient and flush with the seat cushion after unfolding. Utility Model Content

DETAILED DESCRIPTION

[0034] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] As attached Figure 1-10 As shown, a segmented folding sofa chair comprises a seat panel 11, armrests 12, support vertical panels 13, and a back panel 14, and further comprises a folding panel unit 1 hingedly arranged on the lower surface of the seat panel 11, an inclined support panel unit 2 hingedly arranged on the folding panel unit 1, a protruding strip 3 arranged on the armrest 12, and a slot 4 provided on the folding panel unit 1 and engaging with the protruding strip 3 to level the height difference between the upper surface of the seat panel 11 and the upper surface of the armrest 12 that has been removed from the seat panel 11.

[0036] In this embodiment, the segmented folding sofa chair can be used as both a seat and a bed. The seating function is primarily realized by the seat panel 11, the armrests 12, the support risers 13, and the back panel 14. The armrests 12 are detachably mounted on both sides of the seat panel 11. The support risers 13 are located below the seat panel 11 and serve as the primary support structure for the segmented folding sofa chair. The back panel 14 is hingedly mounted on the back of the seat panel 11. When used as a seat, the back panel 14 is vertically mounted on the seat panel 11 to support the user's back. When used as a bed, the back panel 14 is flipped so that it is flush with the seat panel 11. A foldable and retractable support column is provided on the back panel 14 to support the back panel 14, ensuring that it can be used as a bed.

[0037] Furthermore, one end of the folding panel unit 1 is hingedly mounted below the seat panel 11. When unfolded, it can lie parallel to the seat panel 11, allowing it to be used as a sleeping device. Under normal circumstances, the folding panel unit 1 folds into the seat panel 11 under the influence of gravity, remaining perpendicular to the seat panel 11, thereby maintaining the normal use of the sectional folding sofa chair as a seat.

[0038] In addition, the inclined support plate unit 2 is hinged to the other end of the folding plate unit 1 to support the folding plate unit 1 after horizontal expansion, thereby preventing the folding plate unit 1 from being forced to retract into the seat plate 11.

[0039] Finally, the protruding strip 3 is provided on the armrest 12 and engages with the height difference slot 4 provided on the upper surface of the folding plate unit 1. After the folding plate unit 1 is unfolded, there is a height difference between the folding plate unit 1 and the seat plate 11, which may affect the user experience when lying down. Therefore, the armrest 12 can be removed from the seat plate 11, and the protruding strip 3 and the height difference slot 4 are engaged with each other, so that the armrest 12 is plugged into the unfolded folding plate unit 1, thereby compensating for the height difference between the folding plate unit 1 and the seat plate 11, which is easy to operate and flexible to use.

[0040] The folding plate unit 1 includes a first support plate 101 , a hinge plate 102 disposed on the lower surface of the seat plate 11 , and a connecting pin 103 disposed on the first support plate 101 and used to connect the hinge plate 102 .

[0041] In this embodiment, the first support plate 101 is connected to the hinge plate 102 provided on the seat plate 11 through the connecting pin 103 , so that the first support plate 101 is rotatably provided at the lower end of the seat plate 11 .

[0042] The inclined support plate unit 2 includes a support hinge 201 provided on the first support plate 101 , an inclined support plate 202 provided on the support hinge 201 , and a blocking block 203 provided on the first support plate 101 and used to limit the rotation angle of the inclined support plate 202 .

[0043] In this embodiment, the support hinge 201 is provided on the lower surface of the first support plate 101 when horizontally unfolded, and is used to connect the inclined support plate 202 so that the inclined support plate 202 can be folded relative to the first support plate 101. In a normal state, the inclined support plate 202 and the first support plate 101 are folded into the lower end of the seat plate 11. When lying down for use, the first support plate 101 is pulled so that the first support plate 101 is horizontally unfolded and parallel to the seat plate 11. At this time, the inclined support plate 202 is rotated by gravity and becomes perpendicular to the first support plate 101, thereby supporting the first support plate 101. In addition, the inclined support plate 202 can be tilted at a certain angle away from the first support plate 101 to provide a more secure support for the inclined support plate 202. The function of the blocking block 203 is to prevent the inclined support plate 202 from being flipped under force, which would cause the horizontal state of the first support plate 101 to be unable to be maintained.

[0044] There are two first support plates 101 , and the folding plate unit 1 further includes a connecting hinge 104 arranged between the two first support plates 101 , and an inserting rod 105 and a slot 106 arranged on the side ends of the two first support plates 101 for mutual insertion.

[0045] In this embodiment, the first support plates 101 can be provided in two pieces, and the two support plates 101 are hingedly connected by the connecting hinge 104. The insertion rod 105 and the slot 106 are provided at the connecting side ends of the two first support plates 101. When the two support plates 101 are unfolded, the insertion rod 105 on one of the first support plates 101 is inserted into the slot 106 on the other first support plate 101, thereby ensuring that the two first support plates 101 are unfolded and meet the structural stability requirements for lying down. The provision of two first support plates 101 not only makes the sectional folding sofa chair more practical when used as the bedding, but also, the two first support plates 101 are hinged to each other and can be folded into the base 11, which increases the structural flexibility. Moreover, after the inclined support plate 202 is folded into the seat plate 11, it can support and prevent the first support plates 101 from tipping over.

[0046] The folding plate unit 1 further includes an anti-folding plate 107 disposed on one of the first support plates 101 and used to clamp the other unfolded first support plate 101.

[0047] In this embodiment, the anti-folding plate 107 is used to further secure the two first support plates 101 after they are unfolded, thereby evenly distributing the supporting force of the insertion rod 105. The anti-folding plate 107 can be made of a deformable plastic material. When the anti-folding plate 107 engages the first support plate 101, it can be inserted from the side and then slid to the connection between the two first support plates 101. Alternatively, the deformable nature of the plastic can be utilized to pry the anti-folding plate 107 apart and then insert it into the connection between the two first support plates 101, thereby achieving a fixed engagement.

[0048] The inclined support plate unit 2 further includes an anti-slip pad 204 provided on the inclined support plate 202 .

[0049] In this embodiment, the anti-slip pad 204 is arranged at a position where the inclined support plate 202 is away from the first support plate 101. When the inclined support plate 202 supports the first support plate 101, the anti-slip pad 204 can increase the friction between the inclined support plate 202 and the ground, thereby achieving an anti-slip effect and increasing the stability of the vehicle on the inclined support plate 202.

[0050] The inclined support plate unit 2 further includes an expansion groove 205 provided on a side end of the inclined support plate 202 .

[0051] In this embodiment, the unfolding groove 205 is provided at the side end of the inclined support plate 202 . When the folding plate unit 1 needs to be opened or folded, the unfolding groove 205 can be used to make the operation more convenient.

[0052] The support vertical plate 13 is provided with a rotating plate 5 for laterally blocking the folding plate unit 1 and the inclined support plate unit 2 from unfolding, and a baffle 6 is provided on the support vertical plate 13 for limiting the rotation angle of the rotating plate 5 .

[0053] In this embodiment, the rotating plate 5 is arranged on the supporting vertical plate 13, near the position of the folding plate unit 1. One end of the rotating plate 5 is rotatably arranged on the supporting vertical plate 13. In the natural state, the rotating plate 5 is parallel to the supporting vertical plate 13 under the influence of gravity. When the folding plate unit 1 and the inclined support plate unit 2 are folded into the seat plate 11, in order to prevent the folding plate unit 1 and the inclined support plate unit 2 from tipping over and affecting the function of the sectional folding sofa chair as a seat, the rotating plate 5 is rotated so that the rotating plate 5 is perpendicular to the supporting vertical plate 13, and the folding plate unit 1 and the inclined support plate unit 2 are limited and blocked, so that the folding plate unit 1 and the inclined support plate unit 2 are arranged inside the seat plate 11. The function of the baffle 6 is to support the rotating plate 5 after rotation.

[0054] The side end of the seat plate 11 is further provided with a mounting slot 7 for inserting the protruding strip 3 .

[0055] In this embodiment, the mounting slot 7 is used to insert the protruding strip 3, so that the armrest 12 can be detachably provided on the seat plate 11, and the installation and disassembly are more flexible.

[0056] The cross-sectional figures of the height difference slot 4 and the mounting slot 7 are T-shaped or trapezoidal.

[0057] In this embodiment, the cross-sections of the height difference slot 4 and the installation slot 7 are set to be T-shaped or trapezoidal, so that the installation and disassembly of the handrail 12 are more convenient and stable.

[0058] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications are possible within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. These modifications are non-inventive and are protected by patent law as long as they fall within the scope of the claims of the present invention.
