Technical Field

The present application relates to the field of furniture, and in particular to a sofa bed.

Background

Sofa is one of the indispensable household products in our daily life, and it provides space for us to rest, relax and entertain. In order to meet the requirements of sitting and lying at the same time, a sofa with a long length, which is also commonly called as a high-ranked imperial sofa, is generally assembled.

However, the high-ranked imperial concubine of the sofa is often not frequently used in daily life, and intensive furniture becomes a new requirement along with the tension of living space, so that the sofa is required to realize double requirements of sitting and lying on the premise of occupying the smallest space as possible.

Disclosure of Invention

In order to achieve the dual requirements of sitting and lying on the premise of reducing occupied space, the application provides a sofa bed.

The sofa bed adopts the following technical scheme:

the sofa bed comprises a body and at least two independent split bodies, wherein the body is connected with the split bodies and the split bodies are connected with each other through an outsourced surface sleeve; based on the junction of face cover, the components of a whole that can function independently can turn over and stack to the body, also can turn over the seat face that breaks away from the body and tiling.

By adopting the technical scheme, when the split type sofa is overlapped to the body, a sofa which can be sat and has a certain height is formed, and when the split type sofa is turned over and laid flat, a bed which has a relatively low height and can be used for lying is formed; the surface sleeve connection mode is adopted, so that the overturning connection of the split body and the body has certain fault tolerance, and the split body or the body cannot be easily overturned incompletely due to elastic bulge. Therefore, the sofa bed can adjust different postures according to different requirements, and space occupation can be effectively reduced when the sofa bed is not in use in a lying posture.

Optionally, the body comprises a bottom pad and a surrounding baffle fixed relative to the bottom pad; the split type seat cushion comprises two split type seat cushions, wherein the split type seat cushion close to the body is called a seat cushion, the split type seat cushion far away from the body is called a backrest, the seat cushion is folded and covered on a bottom cushion, and the backrest correspondingly abuts against the surrounding baffle and is in a standing position relative to the seat cushion.

By adopting the technical scheme, the backrest function of the backrest is fully exerted, the fence is used as a framework, and the backrest is used as a cushion layer, so that people can lean on the backrest more comfortably.

Optionally, the backrest comprises a support layer and a leaning layer, the support layer being closer to the enclosure than the leaning layer when the backrest is in the standing position, the support layer having a higher hardness than the leaning layer.

By adopting the technical scheme, the supporting layer provides relatively good supporting performance, so that the backrest can not collapse completely when being leaned, and the leaning layer and the surface sleeve on the surface are used as the part directly contacted with the human body, so that the leaning is more comfortable due to softness, and good containing sense is realized.

Optionally, the supporting layer and the leaning layer are both sponges, the density of the sponges is greater than 25kg/m, and the collapse hardness of the sponges of the supporting layer is higher than that of the leaning layer.

By adopting the technical scheme, good support is maintained on the basis of being soft enough.

Alternatively, take the azimuth of the backrest in a flat state as an example; the lower surface of the supporting layer is an inclined surface, an arc surface or a combination of the inclined surface and the arc surface, and the thickness of the supporting layer is gradually reduced from one end close to the cushion to one end far away from the cushion; the reclining layer wraps around the lower surface of the support layer and the end surface away from the seat cushion, and the upper surface of the reclining layer is aligned with the upper surface of the support layer.

By adopting the technical scheme, the leaning layer substantially completely wraps the part of the backrest which can be in direct contact with a human body, so that the body and the head of the human can always lean against the most soft part of the backrest when leaning against; and based on the thickness variation design of the supporting layer, when the force applied by a human body on the leaning layer is transferred to the supporting layer, the sum of acting forces of the supporting layer on leaning is always close to the acting force direction applied by the human body, so that the acting force of dislocation separation between the leaning layer and the supporting layer is smaller, tearing is not easy to occur, and the forward feedback effect is more comfortable for a leaning person, and landslide feeling is not easy to occur. The landslide feeling refers to the feeling when the leaning direction and the backrest deformation direction deviate, and if the deviation amount is large, the human body can feel that the leaning part is relatively weak, and the feeling of stable support like landslide is not realized.

Optionally, the cushion includes a first spring package, a first needled cotton layer wrapping the first spring package, and a first sponge outer layer wrapping the first needled cotton layer, and the face cover wraps the first sponge outer layer.

By adopting the technical scheme, the seat cushion basically contacts with the buttocks of the human body in both sitting and lying postures, and the buttocks are used as the main supporting stress part of the human body and are required to have enough supportability; compared with the sponge, the spring package has higher supporting property, the sponge is used as the outer layer to ensure that the contact surface is soft enough, namely the sponge is mainly deformed when the human body just contacts, so as to ensure high enough buffering capacity and extension wrapping capacity, and then the spring package is deformed by a small margin and then is kept to be supported; thus, not only the sitting or lying comfort is ensured, but also the sufficient supporting performance is ensured.

In addition, the first needled cotton layer constructs the tearing buffer zone between first spring package and first sponge skin, can reduce like this even effectively avoids sponge and spring package to produce wearing and tearing because of the deflection is different.

Alternatively, take the azimuth of the backrest in a flat state as an example; the first sponge outer layer comprises a bottom layer, a peripheral layer and a top layer which are adhered to each other, the end face of the bottom layer, far away from the body, is an arc surface, the minimum thickness of other parts except the arc surface area of the bottom layer is larger than the maximum thickness of the top layer, and the thickness of the bottom layer is gradually reduced from one end, close to the body, to one end, far away from the body.

By adopting the technical scheme, taking the azimuth of the backrest in a flat state as an example, the backrest can be turned over to be in a standing position relative to the cushion, the turning centers of the cushion and the body are positioned at the position relatively upwards of the cushion, and the rotation centers of the backrest and the cushion are positioned at the position relatively downwards; because the cushion is used as a stress part with relatively concentrated stress, the concave degree is obvious, so that the thickness of the part of the bottom layer close to the body can control the final height after compression, on one hand, the drop between the cushion and the body when a person lies on the cushion can be weakened, and on the other hand, the tearing of the surface sleeve connecting part between the cushion and the body is also reduced. In addition, the reduced thickness and the rounded portions also provide clearance for the backrest to be flipped over.

Optionally, the bottom pad includes a second spring package, a second needled cotton layer wrapping the second spring package, and a second sponge outer layer wrapping the needled cotton layer, wherein the wire diameter of the spring in the second spring package is greater than the wire diameter of the spring in the second spring package.

Description of the embodiments

The present application is described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses a sofa bed.

Example 1:

referring to fig. 1 and 2, a sofa bed comprises a body 1 and at least two independent split bodies 10, wherein the body 1 and the split bodies 10 and 10 are connected through an outer cover (not shown in the figure); based on the connection part of the facial mask, the split body 10 can be folded and overlapped to the body 1, and the state is called sitting posture; the seat surface of the body 1 can be folded and unfolded, and this state is called a lying position. The number of the split bodies 10 is determined according to the actual number of the split bodies, and there are some differences in the actual stacking manner according to the number, for example, the split bodies 10 may be placed on the body 1 as a sitting portion, and may be erected as a leaning portion. In the present embodiment, two split bodies 10 are taken as an example; based on the difference in function, the two split bodies 10 are named cushion 2 and backrest 3, respectively.

The body 1 comprises a base 11, a base pad 12 and a surrounding shield 13, wherein the base 11 is a hard frame, and can be a wooden frame, a metal frame or a composite frame. The base 11 may be located only at the bottom of the base pad 12, or may surround the base pad 12 along the peripheral side, or a combination of both, and the base 11 is located at the bottom in this embodiment. The bottom pad 12 and the base 11 can be fixed by gluing, sewing, binding and the like. The enclosure 13 includes a back stop 131 and a side stop 132, both of which are secured to the base 11. The enclosure 13 is also formed by combining a hard frame with a sponge, a fabric and the like.

The connection part of the cover (not shown) of the base cushion 12 and the cover (not shown) of the seat cushion 2 is located at the upper part of the side wall of the base cushion 12, so that the seat cushion 2 covers the surface of the base cushion 12 in a sitting posture. In the lying position, the side wall of the bottom cushion 12 is abutted to the side wall of the seat cushion 2 via the surface sleeve.

The cushion 2 comprises a first spring package 21, a first needled cotton layer 22 wrapping the first spring package 21 and a first sponge outer layer 23 wrapping the first needled cotton layer 22, wherein the first needled cotton layer 22 is thinner and is a soft filler, and the cushion mainly plays a role in reducing abrasion generated between the first sponge outer layer 23 and the first spring package 21. A facing (not shown) surrounds the first sponge outer layer 23. Taking the azimuth of the backrest 3 in a flat state as an example; the first sponge outer layer 23 comprises a bottom layer 231, a peripheral layer 232 and a top layer 233 which are adhered to each other, the end face of the bottom layer 231 away from the body 1 is an arc surface, the minimum thickness of other parts except the arc surface area of the bottom layer 231 is larger than the maximum thickness of the top layer 233, and the thickness of the bottom layer 231 is gradually reduced from one end close to the body 1 to one end far away from the body 1.

The bottom cushion 12 is the same as the components of the seat cushion 2, but the spring wire diameter of the spring package is different, and the wire diameter of the bottom cushion 12 is larger than that of the seat cushion 2, so that the supporting property of the bottom cushion 12 is better. The thickness of the bottom layer 231 is different, the thickness of the bottom layer 231 of the bottom pad 12 is not gradually changed, and the thickness is smaller than the minimum thickness of other parts of the cushion 2 except the cambered surface area. For convenience of distinction, the corresponding components of the base mat 12 are designated as a second spring pack 121, a second needled cotton layer 122, and a second sponge outer layer 123.

In the sitting posture state, the backrest 3 correspondingly abuts against the fence 13 and is in a standing state relative to the cushion 2. In the lying state, the side wall of the backrest 3 is abutted against the side wall of the seat cushion 2. The connection point of the cover of the seat cushion 2 and the cover of the backrest 3 is positioned at the lower part of the peripheral layer 232.

The backrest 3 comprises a supporting layer 31 and a leaning layer 32, the supporting layer 31 is closer to the enclosure 13 than the leaning layer 32 when the backrest 3 is in a standing position, the supporting layer 31 and the leaning layer 32 are spongy, the density of the sponges is required to be more than 25kg/m, and the collapse hardness of the sponges of the supporting layer 31 is higher than that of the leaning layer 32. Taking the azimuth of the backrest 3 in a flat state as an example; the lower surface of the supporting layer 31 is an inclined surface, an arc surface or a combination of the two, and the thickness of the supporting layer 31 gradually decreases from one end close to the cushion 2 to one end far from the cushion 2; the reclining layer 32 wraps around the lower surface of the support layer 31 and the end surface remote from the seat cushion 2, and the upper surface of the reclining layer 32 is aligned with the upper surface of the support layer 31.

The implementation principle of the embodiment 1 is as follows:

when the occupied space needs to be reduced, the cushion 2 is folded and covers the bottom cushion 12, the backrest 3 is folded and abutted against the enclosure 13, and the sofa is correspondingly converted into a sitting posture.

Correspondingly, when lying demands exist, the cushion 2 and the backrest 3 are unfolded and tiled.

Example 2:

referring to fig. 3, this embodiment is different from embodiment 1 in that the enclosure 13 is also adjustable, specifically as follows:

at least four supporting feet 111 are arranged at the bottom of the base 11, and in this embodiment, 4 supporting feet are taken as examples and are respectively close to four corners of the sofa.

The enclosure 13 comprises a back baffle 131 and side baffles 132, the back baffle 131 is hinged with the base 11, and the end face of the base 11 is abutted with the side face of the back baffle 131. The side block 132 is hinged to the back block 131, a snap ring 133 with a notch is fixed to a side wall of the side block 132, the notch of the snap ring 133 faces the backrest 3 in a flat state, and the support leg 111 is embedded in the snap ring 133 and limits the rotational freedom of the side block 132. In this embodiment, the above hinged connection parts are all hinges.

When the side stops 132 are required, the seat base 11 can be turned upwards, and the seat cushion 2 is compressed in the process. Then, the side blocks 132 are turned over to be attached to two sides of the base 11, and then the base 11 is reset, so that the supporting legs 111 are clamped into the clamping rings 133, and the assembly can be completed.

When the side rail 132 is not needed, the operation may be reversed to turn the side rail 132 to the back of the back rail 131. Correspondingly, a magnetic structure is arranged at the corresponding position of the side block 132 and the back block 131, so that the side block 132 is adsorbed on the back of the back block 131. For aesthetic purposes, in this embodiment, the side stops 132 and the back stop 131 are integral with the outer cover material to cover the hinge structure.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
