Description

Technical Field

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

[0002] The existing sofa bed includes a base and a functional component. By adjusting the relative position between the base and the functional component, the main body can be switched between the bed state and the sofa state, so as to meet the different needs of users in different scenarios. The base and the functional component are connected by a connecting component to ensure that the functional component can move along a preset path and enable the main body to accurately switch between the bed state and the sofa state and be reliably positioned. Since the connecting component needs to be set, the structure of the sofa bed is complicated, which not only increases the assembly steps and production costs, but also causes the main body to be unable to switch states due to the damage of the connecting component, shortens the service life and affects the use experience. Content of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides a sofa bed, which includes a base and a functional component that are independently arranged. By independently moving the functional component and assembling it with the base, the main body can be switched between the sofa state and the bed state, which not only simplifies the structure, facilitates assembly and switching, but also improves the use reliability, prolongs the service life and enhances the use experience.

[0004] The utility model is realized in the following way: a sofa bed includes a main body, and the main body includes a base and a functional component that are independently arranged. The functional component can be switched between a support position horizontally joined to the front edge of the base and a backrest position vertically stacked above the rear edge of the base, so that the main body can be switched between the bed state and the sofa state. The base and the functional component that are independently arranged eliminate the connecting piece. By independently moving the functional component and assembling it with the base, the main body can be switched between the sofa state and the bed state, which not only simplifies the structure, facilitates assembly and switching, but also improves the use reliability, prolongs the service life and enhances the use experience.

[0005] Preferably, the base is an integral structure, and the base includes a front support part and a U-shaped surrounding edge part arranged around the rear edge of the support part. The functional component is U-shaped and has the same contour as the surrounding edge part. The relative positions between the support part and the surrounding edge part are fixed to ensure that the relative positions between the functional component and the support part are fixed after the functional component is cooperatively connected with the surrounding edge part, so as to ensure that the main body can accurately switch between the bed state and the sofa state.

[0006] Preferably, when the functional member switches to the support station, the functional member abuts against the front edge of the base from front to back and cooperates with the surrounding edge portion to wrap the support portion, so that the body switches to the bed state with a rectangular vertical projection profile. The functional member moves from front to back and fits against the front wall of the base. The end surface of the functional member is closely attached to the two end surfaces of the surrounding edge portion, so that the support portion is wrapped between the functional member and the surrounding edge portion. The top surfaces of the functional member and the base are flatly joined to form a bed with a flat supporting surface.

[0007] Preferably, the corners of the functional member are provided with transition rounded corners, and the transition rounded corners are provided to eliminate the foreign body feeling at the corners of the functional member and effectively improve the contact comfort.

[0008] Preferably, when the functional member switches to the backrest station, the functional member is stacked on the surrounding edge portion from top to bottom, so that the body switches to the sofa state with the top surface of the support portion facing upward and exposed. The functional member is stacked above the surrounding edge, which is used to form the backrest of the body in the sofa state, facilitating the user to lean on, and also ensuring that the top surface of the support portion can be completely exposed, effectively supporting the user in a sitting position.

[0009] Preferably, the base and the functional member have the same height, so that the body has a flat supporting surface when switching to the bed state, facilitating the user to lie down and improving the lying comfort.

[0010] Preferably, the surrounding edge portion and the functional member have the same vertical projection profile. When the body switches between the sofa state and the bed state, the top surface of the support portion is always facing upward and exposed. The functional member is vertically stacked on the surrounding edge portion, which not only ensures that the top surface of the support portion is completely exposed, facilitating the user to sit on the support portion, but also ensures that the outer side walls of the surrounding edge portion and the functional member are vertically aligned, improving the aesthetics of the body in the sofa state. Moreover, by increasing the contact area between the top surface of the surrounding edge portion and the bottom surface of the functional member, the friction limiting strength is improved, preventing relative displacement between the two, and providing a reliable leaning experience for the user.

[0011] Preferably, both the base and the functional member are formed by stacking an upper sponge layer, a middle sponge layer, and a lower sponge layer arranged in sequence from top to bottom, and the upper sponge layer, the middle sponge layer, and the lower sponge layer have different support properties. By setting the upper sponge layer, the middle sponge layer, and the lower sponge layer with different support properties, different support experiences can be obtained to meet the different needs of users. The upper sponge layer can improve comfort by reducing hardness, the middle sponge layer has both support and comfort by moderately increasing hardness, and the lower sponge layer ensures support by increasing hardness.

[0012] Preferably, a pocket spring assembly is provided inside the support portion, and an assembly cavity for accommodating the pocket spring assembly is formed in the middle sponge layer of the base. The support portion improves the support comfort by means of the built-in pocket spring assembly. The contour of the assembly cavity matches the contour of the pocket spring assembly, which not only limits the pocket spring assembly but also guides the deformation of the pocket spring assembly.

[0013] Preferably, the base is completely wrapped by a first outer cover, and the functional member is completely wrapped by a second outer cover. The contact area between the first outer cover and the second outer cover is fixedly connected by a connecting member, so that the functional member is fixedly connected to the base and maintained in the support position or the backrest position. The first outer cover and the second outer cover respectively wrap the base and the functional member integrally, which not only limits the upper sponge layer, the middle sponge layer and the lower sponge layer forming the base and the functional member, but also facilitates disassembly and independent cleaning, improving the use experience.

[0014] Preferably, the connecting member is a magic tape, a fastener, a non-slip cloth or a zipper, which plays a role in fixing the base and the functional member, ensuring that the main body can be reliably maintained in the bed state or the sofa state.

[0015] The beneficial effects of the present utility model are as follows: The base and the functional member are independently arranged, eliminating the connecting member. By independently moving the functional member and assembling it with the base, the main body can be switched between the sofa state and the bed state, which not only simplifies the structure, facilitates assembly and switching, but also improves the use reliability, extends the service life and enhances the use experience.

[0025] The following further illustrates the substantial features of the present invention in conjunction with the accompanying drawings of the specification and specific embodiments.

[0026] As Figure 1 and 2 shown, a sofa bed includes a body, the body includes a base 1 and a functional member 2 which are independently arranged. The functional member 2 can be switched between a supporting station where it is horizontally joined with the front edge of the base 1 and a backrest station where it is vertically stacked above the rear edge of the base 1, so that the body can be switched between a bed state and a sofa state. The base 1 and the functional member 2 are independently arranged and the relative position between them is variable. By omitting the connecting member 11, the structure is simplified, which is convenient for production and assembly and prolongs the service life. Also, by independently moving the functional member 2 and assembling it with the base 1, the body can be switched between the sofa state and the bed state to meet the usage requirements of users in different scenarios and improve the usage experience.

[0027] In actual operation, the base 1 is an integral structure. The base 1 includes a front - placed supporting part 3 and a U - shaped surrounding edge part 4 arranged around the rear edge of the supporting part 3. The functional member 2 is U - shaped and has the same contour as the surrounding edge part 4. The body can be switched between the bed state and the sofa state through different matching and combination methods between the functional member 2 and the base 1. Specifically:

[0028] When the functional member 2 is switched to the supporting station, the functional member 2 abuts against the front edge of the base 1 from front to back and cooperates with the surrounding edge part 4 to wrap and support the supporting part 3, so that the body is switched to the bed state with a rectangular vertical projection contour. At this time, the functional member 2 is closely joined with the base 1 in the front - to - back direction, and the body is switched to the bed state. The body in the bed state has a flat supporting surface, and the vertical projection of the supporting surface is rectangular to meet the lying needs of users and enable the body to have the function of a bed.

[0029] When the functional member 2 is switched to the backrest station, the functional member 2 is stacked above the surrounding edge part 4 from top to bottom, so that the body is switched to the sofa state with the top surface of the supporting part 3 exposed. When the functional member 2 is in the backrest station, it is vertically stacked above the surrounding edge part 4, so that the top surface of the surrounding edge part 4 is completely blocked by the functional member 2, and the functional part acts as a backrest, enabling the body to have the function of a sofa.

[0030] In actual operation, the surrounding edge part 4 and the functional part 2 have the same vertical projection contour. When the main body switches between the sofa state and the bed state, the top surface of the supporting part 3 is always exposed upward. When the main body is in the sofa state, the functional part 2 is arranged with a vertical projection dislocation from the supporting part 3, and the user can sit on the top surface of the supporting part 3 to provide comfortable support for the user. When the main body is in the bed state, the functional part 2 is flush with the top surface of the supporting part 3 for splicing. The functional part 2 can not only cooperate with the supporting part 3 to form a supporting surface for the user to lie on, but also make the supporting part 3 be wrapped between the surrounding edge part 4 and the functional part 2 to provide comfortable support for the lying user. When the main body is in the sofa state or the bed state, the top surface of the supporting part 3 is always exposed and provides comfortable support for the user, ensuring that the supporting part 3 can be effectively utilized when the main body is in different states and improving the utilization efficiency of the supporting part 3.

[0031] In actual operation, a pocket spring assembly 9 is arranged in the supporting part 3 (as Figure 3 shown). The supporting part 3 is provided with the pocket spring assembly 9 to improve the supporting comfort so as to meet the comfort of the user in the sitting or lying position and improve the use experience.

[0032] In this embodiment, the base 1 and the functional part 2 have the same height so that when the main body switches to the bed state, there is a flat supporting surface, preventing the situation that the supporting surface is uneven due to the height difference between the base 1 and the functional part 2 and ensuring that the user can lie down smoothly.

[0033] In this embodiment, transition rounded corners 10 are arranged at the corners of the functional part 2 (as Figure 6 and 7 shown). When the main body is in the bed state, transition rounded corners 10 are arranged in the area where the corner part of the functional part 2 faces the base 1, and transition rounded corners 10 are also arranged at the front edge end of the base 1, and the two match and fit to ensure the continuous and flat connection of the supporting surface. When the main body is in the sofa state, the transition rounded corners 10 of the functional part 2 face the supporting part 3, effectively improving the comfort of the user's leaning. Moreover, the transition rounded corners 10 arranged at the front edge end of the supporting part 3 can effectively increase the contact area with the user's legs, thereby reducing the foreign body sensation and improving the contact comfort. In addition, transition rounded corners 10 can also be arranged at the ridge line in the middle section of the functional part 2 to effectively improve the comfort when the user leans on the back, and this should also be regarded as a specific embodiment of the present invention.

[0034] In this embodiment, both the base 1 and the functional part 2 are formed by stacking a top sponge layer 5, a middle sponge layer 6 and a bottom sponge layer 7 arranged from top to bottom in sequence (as Figure 4As shown in the figure, the upper sponge layer 5, the middle sponge layer 6 and the lower sponge layer 7 have differentiated support properties. Different functions are obtained by providing the upper sponge layer 5, the middle sponge layer 6 and the lower sponge layer 7 with differentiated hardness, which not only ensures that the base 1 and the functional parts 2 have balanced hardness when assembled to form a bed, but also facilitates batch processing of the base 1 and the functional parts 2, thereby improving assembly efficiency.

[0035] In actual operation, the central sponge layer 6 of the base 1 is provided with an assembly cavity 8 for accommodating the pocket spring assembly 9. The pocket spring assembly 9 is tightly inserted into the assembly cavity 8, which not only improves the positioning effect by reducing the gap between the two, but also guides the deformation of the pocket spring assembly 9, ensuring that the support portion 3 will not be deformed due to the deformation and offset of the pocket spring assembly 9.

[0036] In actual operation, the base 1 is completely wrapped by the first outer cover after the stacking assembly is completed, and the functional part 2 is completely wrapped by the second outer cover after the stacking assembly is completed. The contact area between the first outer cover and the second outer cover is fixedly connected by a connecting member 11, so that the functional part 2 is fixedly connected to the base 1 and maintained in the supporting position or the backrest position, thereby ensuring that the main body is reliably maintained in the bed state or the sofa state.

[0037] In actual operation, the connecting member 11 is a structure that can be independently disassembled and satisfies the requirement that the functional member 2 does not need to move independently along a preset path (e.g. Figure 5 As shown), including Velcro, fasteners, anti-slip cloth or zippers, etc., which not only ensure that the functional part 2 can be firmly connected and positioned with the base 1 after being moved into place, but also facilitate the free movement of the functional part 2, and reduce the failure rate by simplifying the structure of the connecting member 11, thereby extending the service life. The connecting member 11 can be Velcro, fasteners, anti-slip cloth or zippers, etc., all of which should be regarded as specific embodiments of the present utility model. In a preferred embodiment, the connecting member 11 is Velcro, including a male strip rotatably connected to the base 1 and a female patch block fixedly connected to the functional part 2. When the functional part 2 is in the supporting position or the backrest position, it can be adhered and fixedly connected to the male strip on the base 1 through the female patch block, so that the functional part 2 is firmly connected to the base 1 and shaped. One end of the male strip is rotatably connected to the base 1 through an adapter (as shown in FIG. 1 ). Figure 8 As shown), the other end forms an adhesive portion that can be connected to the mother patch block.
