Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a flip-type sofa bed. Background Art

[0002] In many cities, especially in densely populated areas, the space in people's bedrooms and children's bedrooms is often very limited. In such an environment, the limited living space is even more obvious. Most families will purchase a sofa bed, which is used as a sofa during normal times and converted into a bed when guests need to stay overnight. This not only saves money, but also reduces space occupation and increases space utilization. Therefore, a variety of sofa beds have appeared on the market, and there are also various ways to convert between sofa and bed, including folding, flip and pull-out types.

[0003] However, the existing flip-type sofa beds have the following disadvantages: 1. The conversion process of the sofa bed is relatively complicated and inconvenient for the operator to operate. Sofa beds with such a structure not only increase the labor intensity of the operator but also increase the production cost of the sofa bed. 2. Whether it is a folding, flip-up or pull-out sofa bed, the backrest is basically of two types. One is directly fixed, which forms a form similar to a headrest when the sofa bed is unfolded, which is very useless when living in a limited space. The other is that it can be folded backwards and unfolded, but this requires the entire sofa bed to be moved outwards before it can be unfolded, otherwise it will be blocked by the wall and cannot be unfolded. Both types of forms cannot be reasonably utilized.

[0004] Therefore, in order to solve the problem of limited space in small apartments, designing a sofa bed that can increase space utilization, reduce space occupancy, and facilitate rapid conversion to meet the needs of sofas and beds has become an urgent need in the current market. Utility Model Content

[0013] As a further improvement of the above technical solution, the bed body is further provided with a support frame for supporting the bed body, and the support frame is rotatably connected to the bed body via a second rotating shaft.

[0014] As a further development of the above technical solution, a second linkage mechanism is provided between the bed body and the support frame. The second linkage mechanism includes a slide groove, a linkage column slidingly arranged in the slide groove, and a second linkage rod. The slide groove is arc-shaped and is arranged on the bed body. The linkage column is hingedly connected to the support frame through the second linkage rod. When the bed body is flipped up or down, the linkage column slides relatively along the direction of the slide groove and synchronously drives the support frame to rotate around the second rotation axis through the second linkage rod.

[0015] As a further improvement of the above technical solution, the backrest assembly is provided with a driving mechanism for driving it to flip upward or downward.

[0016] As a further improvement of the above technical solution, the driving mechanism is a telescopic cylinder, and the output end of the telescopic cylinder is connected to the backrest assembly.

[0029] Please refer to Figures 1 to 4 The present invention provides a flip sofa bed. The foldable sofa bed will be described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1: A flip sofa bed, comprising a backrest 5 and a cushion 2, wherein the cushion 2 is separately arranged at the front end of the backrest 5, and the backrest 5 is provided with a flip mechanism, specifically as follows Figure 3 As shown, the flipping mechanism is a rotating shaft 3 respectively arranged on both sides of the backrest 5, and the backrest 5 is flipped upward or downward by the rotating shaft 3; when it is initially in the sofa state, the backrest 5 is flipped downward (i.e., forward) by the rotating shaft 3, and at this time the cushion part 2 is adaptively displaced outward, so that the backrest 5 and the cushion part 2 remain flat to form a bed body; when it is initially in the bed body state, the backrest 5 is flipped upward (i.e., backward) by the rotating shaft 3, and at this time the cushion part 2 is adaptively displaced inward close to the backrest 5, so that the backrest 5 and the cushion part 2 form an angle to form a sofa.

[0031] Example 2: Figure 1 and Figure 2 As shown, a flip sofa bed includes a backrest assembly 1 and a cushion portion 2. The backrest assembly 1 includes a backrest portion 5 and a bed portion 6. The bed portion 6 is fixedly arranged at the rear end of the backrest portion 5. The cushion portion 2 is separately arranged at the front end of the backrest portion 5. The bed portion 6 is provided with a flip mechanism. Figure 3As shown, the flipping mechanism is a rotating shaft 3 respectively arranged on both sides of the bed body 6, and the bed body 6 and the backrest 5 are flipped upward or downward by the rotating shaft 3; when it is initially in the sofa state, the bed body 6 and the backrest 5 are flipped downward (i.e., forward) by the rotating shaft 3, and at this time the cushion portion 2 adaptively moves outward so that the backrest 5 and the cushion portion 2 remain flat, and at this time the bed body 6 flatly covers the backrest 5 and the cushion portion 2 to form a bed body; when it is initially in the bed state, the bed body 6 and the backrest 5 are flipped upward (i.e., backward) by the rotating shaft 3, and at this time the cushion portion 2 adaptively moves inward close to the backrest 5, so that the backrest 5 and the bed body 6 form an angle with the cushion portion 2 to form a sofa.

[0032] By providing a flipping mechanism at the backrest assembly 1, the backrest assembly 1 can be flipped upward or downward by the flipping mechanism; when the device is in the sofa state, it is only necessary to flip the backrest assembly 1 downward and synchronously drive the seat cushion part 2 to move outward through the linkage assembly 1 or manually move the seat cushion part 2 outward, so that the backrest assembly 1 and the seat cushion part 2 remain flat to form a bed state; when the device is in the bed state, it is only necessary to flip the backrest assembly 1 upward and synchronously drive the seat cushion part 2 to move inward through the linkage assembly 1 or manually move the seat cushion part 2 inward, so that an angle is formed between the backrest assembly 1 and the seat cushion part 2 to form a sofa, thereby realizing quick and convenient switching, which can be completed quickly without tedious operations such as disassembling the seat cushion; and the backrest assembly 1 can be reasonably utilized, thereby increasing space utilization and reducing space occupancy.

[0033] As a further technical solution of the above embodiments 1 and 2, Figure 1 and Figure 2 As shown, the rotating shaft 1 3 is arranged on both sides of the backrest assembly 1 through the sofa frame, and the backrest assembly 1 flips upward or downward with the rotating shaft 1 3 as the axis.

[0034] As a further technical solution of the above embodiments 1 and 2, Figure 1 and Figure 2 As shown, a linkage mechanism is provided between the seat cushion portion 2 and the backrest assembly 1. This linkage mechanism is a linkage rod 1-4, hingedly connected at one end to the backrest assembly 1 and at the other end to the seat cushion portion 2. When the backrest assembly 1 (i.e., the bed portion 6 and backrest portion 5) is tilted downward, the linkage rod 1-4 synchronously drives the seat cushion portion 2 to move forward (i.e., outward) horizontally, thereby creating space for the backrest portion 5 and maintaining a level position between the backrest portion 5 and the seat cushion portion 2. When the backrest assembly 1 (i.e., the bed portion 6 and backrest portion 5) is tilted upward, the linkage rod synchronously drives the seat cushion portion 2 to move backward (i.e., inward) horizontally, thereby moving it closer to the backrest portion 5, forming an angle between the backrest portion 5 and the seat cushion portion 2 to form a sofa. Alternatively, the consumer can manually pull the seat cushion portion 2. In this embodiment, a linkage rod is preferably used to synchronize the position switching between the backrest assembly 1 and the seat cushion portion 2.

[0035] Example 3: Figure 1 and Figure 2 As shown, in addition to being supported by the backrest 5 and the cushion 2, the bed body 6 is also provided with a support frame 7 for supporting the bed body 6 in order to further support the bed body 6. The support frame 7 is rotatably connected to the bed body 6 by a second rotating shaft 8; when the bed body 6 of the present device is flipped upward to form a sofa state, the support frame 7 is rotated close to the bed body 6 by the second rotating shaft 8 to achieve folding and storage; when the bed body 6 of the present device is flipped downward to form a bed state, the support frame 7 is rotated and unfolded by the second rotating shaft 8 to be perpendicular to the ground to support the bed body 6.

[0036] As a further technical solution of the above embodiment 3, Figure 3 and Figure 4 As shown, Figure 4 The solid line is the relevant part of the linkage mechanism 2, and the other parts of the device are represented by dotted lines for the convenience of viewing and understanding the structure. In order to enable the support frame 7 to be synchronously stored or unfolded with the backrest assembly 1, a linkage mechanism 2 is provided between the bed body 6 and the support frame 7. The linkage mechanism 2 includes a slide 9, a linkage column 10 slidingly arranged in the slide 9, and a linkage rod 2 11. The slide 9 is arc-shaped and is arranged on the bed body 6. The linkage column 10 is hingedly connected to the support frame 7 through the linkage rod 2 11; when the bed body 6 is aligned with the backrest, the linkage column 10 is hingedly connected to the support frame 7 through the linkage rod 2 11. When the bed 6 and the backrest 5 are flipped upward, the linkage column 10 relatively slides along the direction of the chute 9 and synchronously drives the support frame 7 to swing forward through the linkage rod 11, so that the support frame 7 rotates downward around the rotation axis 8, thereby realizing the folding and storage of the support frame 7; when the bed body 6 and the backrest 5 are flipped downward, the linkage column 10 relatively slides along the direction of the chute 9 and synchronously drives the support frame 7 to swing backward through the linkage rod 11, so that the support frame 7 rotates upward around the rotation axis 8, thereby realizing the unfolding of the support frame 7 to support the bed body 6.

[0037] Among them, in order to make the support frame 7 rotate more stably and smoothly around the second rotating shaft 8, a linkage pin and a second slide groove are provided above the second rotating shaft 8. The second slide groove is in an arc shape. The second linkage rod 11 is connected to the support frame 7 through the linkage pin. The linkage pin is slidably set in the second slide groove. When the second linkage rod 11 drives the support rod to swing forward or backward, the linkage pin synchronously slides relatively along the slide groove, thereby making the rotation of the support frame 7 more stable and smooth.

[0038] As a further improvement of the above technical solution, Figure 1 and Figure 2As shown, the backrest assembly 1 is provided with a drive mechanism for driving it to flip upward or downward. The drive mechanism is a telescopic cylinder 12, the output end of which is connected to the backrest assembly 1. Specifically, when initially in the sofa position, the bed body 6 and backrest 5 are driven by the telescopic cylinder 12 to flip downward (i.e., forward) about the rotation axis 13. At this time, the seat cushion 2 adaptively moves outward, allowing the backrest 5 and seat cushion 2 to remain flat. The bed body 6 then evenly covers the backrest 5 and seat cushion 2 to form a bed. When initially in the bed position, the bed body 6 and backrest 5 are driven by the telescopic cylinder 12 to flip upward (i.e., backward) about the rotation axis 13. At this time, the seat cushion 2 adaptively moves inward toward the backrest 5, forming an angle between the backrest 5, the bed body 6, and the seat cushion 2, forming a sofa.

[0039] As a further improvement to the above technical solution, a sliding displacement assembly is provided below the seat cushion portion 2. The sliding displacement assembly is a pulley. By providing a plurality of pulleys below the seat cushion portion 2 for sliding displacement, the seat cushion portion 2 can be quickly displaced. In addition to pulleys, the sliding displacement assembly can also use slide rails and screws to quickly displace the seat cushion portion 2. It can also be provided with a cylinder to achieve automatic displacement. Therefore, it is not limited to pulleys.
