Description

Technical Field

[0001] The present application relates to a piece of furniture, in particular to a sofa bed that can be folded horizontally. Background Art

[0002] In modern living environments, storage and comfort are emphasized. In some densely populated cities and countries, storage and organization are no longer limited to daily utensils. Moreover, because some living environments are not very abundant now, the living area is very compact. As a result, people usually arrange their living environment better in a limited space. The bed is one of the essential household items in people's home life. However, the bed usually occupies a large area and often occupies a considerable living space.

[0003] In order to improve the reasonable use area, people have improved the use of beds to obtain more space for activities. Therefore, the sofa bed industry was born. For some sofa beds with a length of 2 meters, this extra-long functional bed frame is usually designed vertically, but the vertical design will make the overall structure more complicated, requiring more mechanisms and parts to support the extra-long bed frame. Utility Model Content

[0004] The embodiment of the present application provides a horizontally folding sofa bed, which mainly solves the problem of how to realize the dual functions of a bed and a sofa in a limited space while improving its convenience of use and structural stability. Specifically, the problems solved by the technical solution include:

[0005] Space utilization issue: Through the horizontal expansion design, the sofa bed can be expanded into a bed in a smaller space, and can be folded into a sofa shape at normal times, reducing the occupancy of living space.

[0006] Structural stability issues: By setting the abutment surface of the limiter and the first connecting rod assembly, the stability of the left frame when unfolded is ensured to prevent the frame from tipping over due to loose or unstable installation.

[0007] Operational convenience: The unfolding and folding operations of the sofa bed have been simplified, allowing users to easily transform the sofa into a bed, or fold the bed into a sofa, improving convenience of use.

[0008] The simplicity of structural design: By using square tubes to bend to prepare the left frame, connectors and right frame, and adopting elastic parts and leg torsion tubes, the structure of the sofa bed is simplified, making production and assembly more efficient.

[0009] Bed surface support issues: By setting up a flexible bed surface, cross steel wires and sofa cushions, different levels of bed surface support are provided to adapt to different usage needs and improve sleeping comfort.

[0010] Appearance and texture issues: The square tube design not only improves the structural stability, but also makes the appearance of the sofa bed more modern and textured, in line with the aesthetic requirements of modern homes.

[0011] In summary, the technical solution of the present application solves the problems of the sofa bed in terms of space utilization, structural stability, operational convenience, structural simplicity, bed surface support and appearance texture through a series of innovative designs.

[0037] See also Figures 1 to 4 , Figure 1 It is a three-dimensional diagram of the unfolded state of the horizontally lying two-fold sofa bed of the present application, Figure 2 yes Figure 1 Side view of Figure 3 yes Figure 1 A partial enlarged view of Figure 4 It is a three-dimensional diagram of a horizontally lying two-fold sofa bed in a folded state; as shown in the figure, the horizontally lying two-fold sofa bed 1 of this embodiment includes a fixed base frame 2, a first connecting rod assembly 3, a left frame body 4, a connecting member 5, a right frame body 6 and a supporting member 7. A limiting member 201 is provided on the fixed base frame 2. The fixed base frame 2 is a steel plate on both sides of the length direction of the sofa body frame. One end of the first connecting rod assembly 3 is pivotally connected to the fixed base frame 2, and the other end of the first connecting rod assembly 3 is pivotally connected to the left frame body 4. The left frame body 4 is stored or unfolded on the fixed base frame 2 through the rotation of the first connecting rod assembly 3. As shown Figure 4As shown, when the left frame 4 receives the fixed base frame 2, the left frame 4 rotates to the bottom of the fixed base frame 2 via the first connecting rod assembly 3. Figure 2 As shown, when the left frame 4 is unfolded on the fixed base frame 2, the left frame 4 is rotated to the top of the fixed base frame 2 through the first connecting rod assembly 3, and the left frame 4 is in a horizontal state. The first connecting rod assembly 3 has an abutting surface 301 corresponding to the limiter 201. When the left frame 4 is unfolded on the fixed base frame 2, the abutting surface 301 of the first connecting rod assembly 3 abuts against the limiter 201 to prevent the first connecting rod assembly 3 from rotating, preventing the left frame 4 from opening too far, and ensuring the flatness and stability of the frame.

The right frame 6 can be stored above the left frame 4 or unfolded on one side of the left frame 4 through the connecting member 5. The supporting member 7 is pivotally connected to the bottom of the right frame 6 to support the right frame 6. When the right frame 6 is stored above the left frame 4, the supporting member 7 is turned over to the top of the right frame 6. After the right frame 6 is stored above the left frame 4 through the connecting member 5, the supporting member 7 is turned over to the top of the right frame 6 and abuts against the right frame 6, and then the left frame 4 stores the fixed bottom frame 2, driving the right frame 6 to descend and store it in the sofa main frame, forming a sofa shape. When the right frame 6 is unfolded on one side of the left frame 4 through the connector 5, the support member 7 supports the right frame 6, and the left frame 4, the connector 5 and the right frame 6 are all in a horizontal state and form a bed state. In this embodiment, the left frame 4, the connector 5 and the right frame 6 are made of bent square tubes. Through the square tube design, the production stability is better than the current frame design using round tubes, and the strength of the square tube is higher than that of the round tube, which ensures higher production accuracy and production stability, and can improve the overall product quality. At the same time, the square tube movement will be smoother, the overall structure will be simpler, the operation will be more convenient, the appearance will be more textured, more in line with the aesthetics of modern people, and the connection between the parts and the square tube will be smoother and fit more closely. Angle steel can be used for the support member 7.
