Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a folding sofa bed. Background Technology

[0002] With the development of society and economy, people's material needs are getting higher and higher. For example, various household items are needed in life. In places such as the living room, a sofa is usually needed, and in the bedroom, a bed is needed. However, when using small single rooms or rental rooms, if a sofa and a bed are placed at the same time, the room will become more crowded, and each piece of furniture has a relatively single function, making it very inconvenient to use.

[0003] To address the aforementioned problems, this application proposes a folding sofa bed. Utility Model Content

[0004] This utility model provides a folding sofa bed to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model provides a folding sofa bed, including a bed frame;

[0006] The bed frame contains a small bed board and a large bed board, with the large bed board located behind the small bed board.

[0007] The bed frame is equipped with a connecting mechanism on each of its two sides. The two connecting mechanisms are located on both sides of the connection between the small bed board and the large bed board. The large bed board and the small bed board are connected to the bed frame through the two connecting mechanisms.

[0008] The connecting mechanism consists of support bar one, L-shaped support plate one, support bar two, L-shaped support plate two, arc-shaped connecting bar, connecting plate and tension spring. Support bar one and support bar two are movably connected to the inner side of the bed by pins. Support bar one is located in front of support bar two. L-shaped support plate one and L-shaped support plate two are movably connected to the top of support bar one and support bar two by pins, and L-shaped support plate one and L-shaped support plate two are fixedly connected to the sides of the small bed board and the large bed board by bolts.

[0009] Preferably, the bed frame includes two side beds distributed on the left and right, the connecting mechanism is installed on the inner side of the side beds, and two large beams distributed front and back are fixedly connected between the two side beds by bolts.

[0010] Preferably, a retaining strip is fixedly connected to the inner side of one of the beams.

[0011] Preferably, the connecting plate is welded and fixed to the inner side of the support bar, and the two ends of the tension spring are respectively fixedly connected to the end of the connecting plate and the inner rear part of the bed edge.

[0012] Compared with related technologies, the folding sofa bed provided by this utility model has the following beneficial effects:

[0013] By replacing the traditional bed board with a structure consisting of a small bed board and a large bed board, and then connecting the small bed board and the large bed board with a connecting structure and installing them inside the bed frame, when you need to convert the bed into a sofa mode, you only need to stand the large bed board upright and tilt it, and then adjust the position of the small bed board to form a sofa. The same piece of furniture has two usage modes, which is very suitable for use in small spaces. It is also simple to operate and very convenient to use. Attached Figure Description

[0019] Implementation examples, by Figure 1-4 As shown, this utility model includes a bed frame;

[0020] Small bed board 5 and large bed board 6 are installed inside the bed frame, and the large bed board 6 is located behind the small bed board 5;

[0021] Connecting mechanism 4: A connecting mechanism 4 is installed on each side of the inside of the bed frame. The two connecting mechanisms 4 are located on both sides of the connection between the small bed board 5 and the large bed board 6. The large bed board 6 and the small bed board 5 are connected to the bed frame through the two connecting mechanisms 4.

[0022] The connecting mechanism 4 consists of a support bar 41, an L-shaped support plate 42, a support bar 43, an L-shaped support plate 44, an arc-shaped connecting bar 45, a connecting plate 46, and a tension spring 47. The support bar 41 and the support bar 43 are movably connected to the inside of the bed side 1 by pins. The support bar 41 is located in front of the support bar 43. The L-shaped support plate 42 and the L-shaped support plate 44 are movably connected to the top of the support bar 41 and the support bar 43 by pins, and the L-shaped support plate 42 and the L-shaped support plate 44 are fixedly connected to the sides of the small bed board 5 and the large bed board 6 by bolts.

[0023] The bed frame includes two side beds 1 distributed on the left and right, and the connecting mechanism 4 is installed on the inside of the side beds 1. The two side beds 1 are fixedly connected by bolts to two large beams 2 distributed in front and behind.

[0024] One of the main beams 2 has a baffle 3 fixedly connected to its inner side. When using the sofa mode, the small bed board 5 needs to be tucked into the bed frame. At this time, the front of the small bed board 5 rests on the baffle 3, and the front of the small bed board 5 can be kept flush with the main beam 2.

[0025] The connecting plate 46 is welded and fixed to the inner side of the support bar 41. The two ends of the tension spring 47 are fixedly connected to the end of the connecting plate 46 and the inner rear part of the bed side 1, respectively. The connecting structure 4 can not only be used to connect the small bed board 5 and the large bed board 6 together, but also to install the small bed board 5 and the large bed board 6 inside the bed frame, so that the bed frame, the connecting mechanism 4, the small bed board 5 and the large bed board 6 can cooperate with each other to quickly switch between sofa and bed.

[0026] Working principle:

[0027] The connecting mechanism 4 can connect and support the small bed board 5 and the large bed board 6, while also adapting to the angle between them. In sofa mode, the large bed board 6 is upright and tilted, connected to the back of the small bed board 5, while the small bed board 5 is entirely inside the bed frame. The front edge of the small bed board 5 is supported by the baffle 3 and kept flush with the main beam 2. In this mode, one can sit on the small bed board 5 and lean against the large bed board 6. When it is necessary to adjust to bed mode, the small bed board 5 can be lifted from the bed frame and extended forward, while the large bed board 6 is also laid flat through the connection mechanism 4. At this time, the small bed board 5 and the large bed board 6 are connected together through the connecting mechanism 4 and supported by the two main beams 2, thus enabling it to be used as a bed.
