Technical Field
[0001] This utility model relates to the field of sofa technology, specifically a dual-purpose sofa that can adjust sitting and reclining postures. Background Technology
[0002] A reclining sofa is a type of furniture that combines the functions of a seat (sofacial chair) and a bed (bed). It typically achieves its transformation through a built-in mechanical structure (such as a pull rod, sliding rail, folding mechanism, or pull-out mechanism), allowing for easy switching between "sofa mode" and "bed mode." For spaces with limited capacity, such as apartments, studios, small living rooms, or studies, reclining sofas are a perfect solution. During the day, they are comfortable sofas, and at night, they can be pulled out to become beds, eliminating the need for a separate bedroom or a bed that occupies a lot of space.
[0003] There are many types of sofas that allow for sitting or reclining. One type allows for switching between sitting and reclining modes by simply flipping the seat cushion 180 degrees. The armrests on both sides of the seat cushion can be used as supports after the cushion is flipped. The structure is simple and easy to operate. However, in actual use, the surface of the armrests is sometimes covered with a layer of soft leather for decoration and aesthetic purposes. When the seat cushion is flipped open, the soft leather layer on the armrests is in contact with the ground and is compressed. After a period of use, the soft leather layer will be damaged due to compression and friction. To avoid this situation, a two-in-one sofa that allows for adjustment of sitting and reclining postures is provided. Utility Model Content
[0004] The purpose of this utility model is to provide a dual-purpose sofa that can achieve adjustable sitting and reclining posture in order to solve the problems mentioned above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reversible sofa capable of adjusting sitting and reclining postures, comprising a sofa assembly consisting of a sofa body, a reversible seat cushion, and reversible hinges. The reversible seat cushion is located above the fixed seat cushion portion of the sofa body. The two sides of the reversible seat cushion are rotatably connected to the sofa body via reversible hinges. Adjustable armrest assemblies are provided on the top two sides of the reversible seat cushion. When the reversible seat cushion is not unfolded, the adjustable armrest assemblies are used as armrests. When the reversible seat cushion is unfolded, the adjustable armrest assemblies are used as support legs.
[0006] The adjustable handrail assembly includes a fixed post, a support plate, a handrail base, and a soft leather layer;
[0007] Two fixing columns are provided, the support plate is fixed between the two fixing columns, and the fixing columns and the support plate are fixed to the top two sides of the flip-up cushion;
[0008] The armrest seat is rotatably connected between two fixed columns, and the lower surface of the armrest seat is in contact with the upper surface of the support plate to achieve horizontal stability of the armrest seat. The soft leather layer is bonded and fixed to the upper surface of the armrest seat for decorative effect.
[0009] Before the flip-up cushion is opened, the armrest is rotated 180 degrees so that the lower surface of the armrest faces upward, so that the soft leather layer does not contact the ground when the flip-up cushion is opened.
[0010] As a further embodiment of this utility model: the adjustable handrail assembly also includes a locking groove, a retraction groove, a T-shaped slide groove, a T-shaped telescopic column, a locking block, and a spring;
[0011] The locking grooves are symmetrically opened on both sides of a fixed column with the pivot axis of the armrest seat as the center.
[0012] The contraction groove is formed at the front end of the armrest seat, the T-shaped slide groove is formed on the inner wall end face of the contraction groove, the T-shaped telescopic column is horizontally slidably installed on the inner side of the T-shaped slide groove and protrudes into the interior of the contraction groove and is fixedly connected to the locking block, the locking block protrudes to the outside of the armrest seat and engages with a locking groove to realize the horizontal locking of the armrest seat;
[0013] The springs are distributed inside the T-shaped groove and located at the rear end of the T-shaped telescopic column, and are used to provide horizontal thrust to the T-shaped telescopic column.
[0014] As a further improvement of this utility model: the soft leather layer only covers the upper half of the armrest seat, and no soft leather layer is provided at the position where the armrest seat rotates and contacts the support plate.
[0015] As a further improvement of this utility model: the upper surface of the fixed seat cushion of the sofa body and the upper and lower surfaces of the flip-up seat cushion are both covered with sponge.
[0016] As a further improvement of this utility model: when the flip-up cushion is flipped open, the upper surface of the flip-up cushion is flush with the upper surface of the fixed cushion part of the sofa body, and the lower surface of the armrest is flush with the upper surface of the support legs of the sofa body.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] By setting up an adjustable armrest assembly with a rotating armrest seat, the armrest seat is rotated 180 degrees before the reversible seat is opened. After the reversible seat is opened, the armrest seat contacts the ground, and the armrest seat, fixed column, and support plate together act as a support. At this time, the soft leather layer is distributed upwards and does not contact the ground, effectively avoiding the soft leather layer from being squeezed or damaged by friction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-5 In this embodiment of the utility model, a dual-purpose sofa capable of adjusting sitting and reclining postures includes a sofa assembly 1 consisting of a sofa body 101, a flip-up cushion 102, and a flip hinge 103. The flip-up cushion 102 is located above the fixed cushion portion of the sofa body 101. The two sides of the flip-up cushion 102 are rotatably connected to the sofa body 101 via the flip hinge 103. Adjustable armrest assemblies 2 are provided on the top two sides of the flip-up cushion 102. When the flip-up cushion 102 is not unfolded, the adjustable armrest assemblies 2 are used as armrests. When the flip-up cushion 102 is unfolded, the adjustable armrest assemblies 2 are used as legs.
[0027] The adjustable handrail assembly 2 includes a fixed column 201, a support plate 202, a handrail seat 203, and a soft leather layer 204;
[0028] There are two fixing posts 201, and the support plate 202 is fixed between the two fixing posts 201. The fixing posts 201 and the support plate 202 are fixed to the top sides of the flip-up cushion 102.
[0029] The armrest seat 203 is rotatably connected between two fixed columns 201, and the lower surface of the armrest seat 203 is in contact with the upper surface of the support plate 202 to achieve horizontal stability of the armrest seat 203. The soft leather layer 204 is bonded and fixed to the upper surface of the armrest seat 203 for decorative effect.
[0030] Before the flip-up cushion 102 is flipped open, the armrest 203 is flipped 180 degrees so that the lower surface of the armrest 203 faces upward, so that the soft leather layer 204 does not contact the ground when the flip-up cushion 102 is flipped open.
[0031] The adjustable handrail assembly 2 also includes a locking groove 205, a retraction groove 206, a T-shaped slide 207, a T-shaped telescopic column 208, a locking block 209, and a spring 210;
[0032] The locking groove 205 is symmetrically opened on both sides of a fixed post 201 with the pivot axis of the armrest seat 203 as the center;
[0033] A contraction groove 206 is formed at the front end of the armrest seat 203, a T-shaped slide groove 207 is formed on the inner wall end face of the contraction groove 206, a T-shaped telescopic column 208 is horizontally slidably installed on the inner side of the T-shaped slide groove 207 and protrudes into the interior of the contraction groove 206 and is fixedly connected to the locking block 209, and the locking block 209 protrudes into the outside of the armrest seat 203 and engages with a locking groove 205 to achieve the horizontal locking of the armrest seat 203;
[0034] Spring 210 is distributed inside the T-shaped groove 207 and located at the rear end of the T-shaped telescopic column 208, and is used to provide horizontal thrust to the T-shaped telescopic column 208.
[0035] In this embodiment: When this sofa is in daily use, it is in "sofa mode", with the soft leather layer 204 on its armrest 203 facing upwards (e.g., Figure 1 The armrest seat 203 can be equipped with a recessed structure for placing a quilt. When you need to switch to "bed mode", the operation steps are as follows:
[0036] First, manually press the locking block 209 to retract it into the retraction groove 206, thus separating the locking block 209 from the locking groove 205. Then, rotate the armrest seat 203 to rotate it 180 degrees. At this time, the locking block 209 is aligned with another locking groove 205. After releasing the pressure on the locking block 209, the locking block 209 pops out under the elastic force of the spring 210 and locks into the other locking groove 205, thus fixing the position of the armrest seat 203. At this time, the soft leather layer 204 is distributed downwards.
[0037] Afterwards, manually pull the flip-up cushion 102 to flip it 180 degrees, and its armrest 203 contacts the ground. The armrest 203, the fixed column 201, and the support plate 202 together act as a support. At this time, the soft leather layer 204 is distributed upward and does not contact the ground, effectively preventing the soft leather layer 204 from being squeezed or damaged by friction.
[0038] It should also be noted that when the armrest seat 203 is in a horizontal state, the lower surface of the armrest seat 203 is in contact with the upper surface of the support plate 202, that is, the rotatable angle of the armrest seat 203 is 180 degrees. When the armrest seat 203 is pressed against the ground, the support plate 202 provides support for the armrest seat 203.
[0039] Please refer to this carefully. Figures 1-3 The soft leather layer 204 only covers the upper half of the armrest seat 203, and the soft leather layer 204 is not provided at the position where the armrest seat 203 rotates and contacts the support plate 202.
[0040] In this embodiment: This structure prevents the soft leather layer 204 from contacting the support plate 202, thus avoiding the soft leather layer 204 being squeezed by the support plate 202.
[0041] Please refer to this carefully. Figures 1-4 The upper surface of the fixed seat cushion of the sofa body 101 and the upper and lower surfaces of the flip-up seat cushion 102 are covered with sponge.
[0042] When the flip-up cushion 102 is flipped open, the upper surface of the flip-up cushion 102 is flush with the upper surface of the fixed cushion part of the sofa body 101, and the lower surface of the armrest seat 203 is flush with the upper surface of the support legs of the sofa body 101.
[0043] In this embodiment: the above structure allows the flip-up cushion 102 to be flipped open, and the upper surface of the flip-up cushion 102 and the upper surface of the fixed cushion part of the sofa body 101 are in a soft state, ensuring the comfort of lying down (it should be noted that the flip hinge 103 is a commonly used flip-up hardware, and the changes of the flip hinge 103 during the flipping process will not be described in detail here).
[0044] 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.
