Multifunctional sofa bed

Technical Field

The invention relates to the field of articles for daily use, in particular to a multifunctional sofa bed which meets the requirements of users in various using states, such as dependence, sitting and standing rest or lap and lying rest.

Background

The sofa is a seat appliance with a long history and used for assisting people to rest, and is widely used in different environmental places. With the continuous abundance and diversification of people's lives, people's demands for sofas are also constantly changing.

The conventional sofa is mainly a multi-seat chair with cushions, and armrests are arranged on two sides of the sofa, and the sofa is mainly used by a plurality of people. In modern life, people pay more and more attention to personalized experience, and most young men and women are reluctant to be restricted by the traditional concept, for example, the people do not like the traditional sofa with a fixed structure.

Referring to fig. 1, the lazy sofa 1P is a new type of sofa primarily intended for personal use, created on demand. Unlike conventional sofas, they are of irregular structural design and filled with foam particles, when a person sits on top, they form a sitting nest under the pressure of the person, thus assisting the rest of the person.

Lazy people's sofa 1P has broken through the design thinking of traditional fixed knot structure sofa to a certain extent for the sofa is more individualized to a certain extent, but it still has some aspects that can not satisfy current demand.

First, the lazy sofa 1P meets the personalized requirements to some extent, but it can only provide a use state, that is, a state in which a person sits or rests on it. For modern people, the idea is constantly changing, and the state of needing to use the device is also constantly changing, for example, the device is more expected to sit when sitting, lie when lying, and is not limited by a state.

Secondly, modern life is more and more complicated and diversified, and living space is more and more valuable. Among the limited resources, it is desired to satisfy various needs while minimizing the number, that is, it is desired that one article can perform various functions, reducing the occupation of space, in other words, people desire a life that is simple and not simple. Similarly, for the lazy sofa 1P, which is substantially in the irregular shape, it can only provide one function, so that when one person buys the sofa, another comfortable sleeping tool may be bought, which only increases the complexity of life.

Thirdly, the lazy sofa 1P is an irregular structure design, which is formed by splicing a plurality of cloth materials into an approximately conical structure and then filling the sofa with particles, and compared with the traditional sofa with a definite shape, the lazy sofa has a more complicated shape manufacturing aspect.

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The present invention provides a multi-function sofa sleeper 10, wherein the multi-function sofa sleeper 10 has a plurality of deformation states for users to use in different using postures or using requirements.

The multifunctional sofa bed 10 has a main body 11 and a filler 12, the main body 11 has an inner space 1001, and the filler 12 is filled in the inner space 1001 so that the inner space 1001 is filled.

The main body 11 of the multifunctional sofa bed 10 has a first surface 101 and a first surface 101, the first surface 101 and the second surface 102 are disposed to face each other to form the inner space 1001, and the filler 12 is accommodated in the inner space 1001 between the first surface 101 and the second surface 102, so that the space between the first surface 101 and the second surface 102 is expanded, and the multifunctional sofa bed 10 has a certain thickness.

The filler 12 is exemplified by, but not limited to, polyurethane material, memory foam, foam particles. Preferably, the filler 12 is a foam particle, and when one of the parts or surfaces of the multifunctional sofa bed 10 is pressed by the body part, the filler 12 can move, so that the pressed position and the shape of the body part of the user are matched to form a shape adapted to the body part, that is, the multifunctional sofa bed 10 is fitted to the body part.

The multi-function sofa bed 10 has at least two joining edges 104, and the edges of the first side 101 and the second side 102 are joined to form two joining edges 104. It should be noted that the bonding manner may be sewing, heat sealing, or integrally bonding, that is, the opposite sides are formed at the turning positions of the first side 101 and the second side 102, for example, the first side 101, the second side 102, and the bonding side 104 are formed by folding the raw materials in the same plane and then sewing.

The multifunctional sofa bed 10 has a combination component 13, and the combination components 13 are respectively arranged on the combination edges 104, so that the combination edges 104 are combined or separated with each other to assist in forming the plurality of deformation states. That is, the various deformation states of the multi-function sofa bed 10 are formed in the coupling or opening transition of the coupling side 104. Specifically, the combination assembly 13 includes a first combination member 131 and a second combination member 132, and the first combination member 131 and the second combination member 132 are respectively disposed with the two combination edges 104 so as to combine the two combination edges 104 separated from each other.

The coupling member 13 may be a snap member, a button member, a snap member, a hook and loop fastener, a zipper member, or the like, which can couple the two coupling edges 104 separated from each other. That is, the first coupling member 131 and the second coupling member 132 are two parts that can be coupled to each other, such as two halves of a zipper, two halves of a snap, a button hole and a button of a button assembly, two halves of a hook and loop fastener, a male button and a female button of a snap. Preferably, the set of coupling members 13 is a zipper member, and two halves of a zipper coupled to each other are respectively provided to the coupling rims 104, and when two coupling rims 104 need to be coupled to each other, the zipper members are coupled to each other, thereby coupling the coupling rims 104 to each other. It is worth mentioning that the coupling assembly 13 is implemented as a zipper in such a way that the coupling edges 104 can be continuously coupled, so that the coupling edges 104 can be stably coupled with each other when the multifunctional sofa bed 10 receives a pressing force in a zipper direction or a vertical direction, thereby stably supporting the user, i.e., facilitating to form another deformation state, and requiring only one zipper-closing operation, and the operation is simple and convenient.

Preferably, in this embodiment of the present invention, the multi-function sofa sleeper 10 has two of the binding edges 104 and a free edge 105. The joined edges 104 are oppositely disposed and the free edges 105 are oppositely disposed, thereby forming a substantially square development plane. Further, in this embodiment of the present invention, the multi-function sofa bed has two free edges 105, and two combined edges 104 and two free edges 105 are spaced apart from each other.

Further, the length of the free edge 105 is greater than the length of the coupling edge 104, thereby forming a rectangle extending along the free edge 105, thereby providing a support configuration suitable for the height of a human body. That is, the first face 101 and the second face 102 form a square structure.

Further, the first surface 101 and the second surface 102 form a symmetrical structure, that is, the first surface 101 and the second surface 102 are identical in shape, that is, the first surface 101 and the second surface 102 are identical in terms of usage function. Of course, in other embodiments of the present invention, the first side 101 and the second side 102 can be distinguished in other ways, such as providing different surface materials, or providing different color patterns, to help a user distinguish the first side 101 from the second side 102.

In other embodiments of the present invention, referring to fig. 12A-12C, the first surface 101 and the second surface 102 may also be formed in other shapes, such as triangle, tetrahedron, pentagon, etc., and the combination members 13 are respectively disposed on two edges thereof, thereby forming different variations. The positions and the number of the combined edges 104 and the free edges 105 are adjusted accordingly. The bonding element 13 may be disposed along the bonding edge 104 as a whole, or may be disposed at a partial region of the bonding edge 104, and the present invention is not limited in this respect.

Referring to fig. 2 and 7, the multi-function sofa 10 has an expanded state 100, wherein the multi-function sofa 10 extends generally flat in the expanded state 100 to provide a generally flat flexible resting position for the user U. By way of example and not limitation, the multi-function sofa bed 10 in the deployed state 100 is suitable for use in the U-pass prone position, i.e., the multi-function sofa bed 10 in the deployed state 100 has the function of a bed or a flat cushion, facilitating the user U to have a lying down rest at any time and anywhere. For example, at home, the user U can place it on any flat ground, such as a place near a window, thereby conveniently enjoying scenery outside the window or enjoying beautiful sunlight. For example, in an office, the user U can conveniently place the chair on the bottom surface near the seat during noon break, and thus can enjoy a short and comfortable noon break even in an office and can take a noon break while lying.

By way of example and not limitation, the size of the multi-function sofa sleeper 10 in the expanded state 100 along the joined edges 104 or along the width thereof may range from 0.5m to 1.1m, and along the free edges 105 or along the length thereof may range from 1.5m to 2.0 m.

Preferably, the size of the multi-function sofa bed 10 in the unfolded state 100 is approximately 0.8m along the joining edge 104 and approximately 1.8m along the length of the free edge 105.

Referring to fig. 4 and 8, in the unfolded state 100, the ends of the multi-function sofa bed 10 can be arbitrarily folded, thereby forming a pillow portion, i.e., the height of the pillow portion is increased relative to the unfolded plane of the multi-function sofa, so that the user can conveniently rest his head in the lying state or sit up.

Referring to fig. 5A-5C, and fig. 9, the multi-function sofa bed 10 has an engaged state 200, wherein the engaging edges 104 of the multi-function sofa bed 10 are engaged with each other by the engaging members 13 in the engaged state 200, thereby forming a single-layered roll. For example, in one embodiment, the multifunctional sofa bed 10 is folded back to close the combining edges 104, and further, the combining edges 104 are combined with each other by the combining component 13 to form the combining state 200. Preferably, in the coupling state 200, the coupling edges 104 of the multi-purpose sofa bed 10 are coupled to each other by a set of zippers respectively provided to the coupling edges 104 such that the coupling edges 104 are continuously coupled. The zipper assembly is arranged along the direction in which the coupling flange 104 extends.

Further, in the coupled state 200, the coupling edges 104 of the multifunctional sofa bed 10 are coupled to each other to form a top surface 201 and a bottom surface 202 and two side surfaces 203, and the top surface 201 and the bottom surface 202, i.e. the first surface 101 or the second surface 102 of the multifunctional sofa bed 10, are formed by being curled, that is, the first surface 101 or the second surface 102 forms a closed structure around. The two sides 203 are formed by the free edge 105 of the multi-function sofa sleeper 10. That is, the multi-function sofa sleeper 10 is converted from a single-layered thickness to a laminated thickness in the coupled state 200. The length edges transition from the original longer extended state to a shorter rolled state, while the width edges transition from the original separate state to being reformed by folding.

In the coupled state 200, the multi-function sofa bed 10 is formed in a single-layered roll structure such that the extension area of the multi-function sofa bed 10 in a plane is reduced and the height in a vertical direction is increased. In the coupled state 200, the multi-function sofa sleeper 10 is adapted to form a high seat cushion or to act as a back rest cushion. For example, referring to fig. 9, the user U can sit on the top surface of the coupled state 200 of the multi-function sofa bed 10 with his feet placed on the bottom surface, thereby being able to read or entertain and relax conveniently. That is, the multi-function sofa bed 10 has a seat function in the coupled state 200, and has a reduced area but an increased thickness with respect to the unfolded state 100, and is more suitable for a sitting posture.

Referring to fig. 5A-5C, in one embodiment of the present invention, in the coupled state 200, the set of coupling members 13 is located below the top surface 201, that is, the set of coupling members 13 is located at the bottom surface 202. In another embodiment of the present invention, in the coupled state 200, the set of coupling members 13 is located above the bottom surface 202, that is, the set of coupling members 13 is located at the position of the top surface 201. In another embodiment, in the coupled state 200, the set of coupling members 13 is located on a side or lateral edge of the top surface 201.

It is worth mentioning that the user U can move the coupling assembly 13 to different positions, such as the top, bottom or side, depending on the situation, when using it. In other words, in the coupled state 200, the moved position of the coupling assembly 13 does not limit the basic function of the multi-function sofa 10 as a seat cushion or a back cushion. Preferably, the coupling member 13 is located at the bottom surface 202 of the coupled state 200 of the multi-function sofa bed 10 in the coupled state 200, that is, the coupling member 13 is located below the seating position, that is, the coupling member 13 does not directly contact the body seating portion of the user U, thereby reducing the uncomfortable feeling due to the possible unevenness of the coupling member 13.

Referring to fig. 6A to 6C, and fig. 10, the multifunctional sofa bed 10 has an upright position 300, in the upright position 300, the combining edges 104 of the multifunctional sofa bed 10 are combined with each other by the combining component 13, and the multifunctional sofa bed 10 is upright along the width direction, or the multifunctional sofa bed 10 is upright along the extending direction of the combining component 13. In other words, in the standing state 300, the multifunctional sofa bed 10 in the coupled state 200 is stood to be formed with one of the side surfaces of the coupled state 200 being a supporting bottom surface, and one of the side surfaces of the coupled state 200 being a top surface of the standing state 300. More specifically, in the upright position 300, the two joining edges 104 join each other and are located in the vertical direction, the two free edges 105 respectively form a bottom surface 302 for support and a top surface 301 located above, and the first surface 101 or the first surface 102 is surrounded to form a peripheral side 303. The bottom surface 302 is placed on an end surface of the ground.

It is worth mentioning that the multifunctional sofa bed 10 is made of flexible material, and the filler 12 is foam particles, which has good mobility, and can move to form a shape corresponding to the shape of the body part under different forces applied to different positions.

In the upright position 300, the top surface 301 of the multi-purpose sofa sleeper 10 is forced by external force to form a sitting nest 304, and the sitting nest 304 is suitable for a user to sit in. That is, in the coupled state 200, the multi-function sofa sleeper 10 has a sofa function. The seat 304 is formed by external force, so that the periphery of the top surface forms a sofa back and sofa armrest.

More specifically, in the upright position 300, when the user U applies pressure to one side of the top surface 301 of the multi-function sofa sleeper 10, or sits down with the body of the user U near the top surface, the filler 12 moves from the side with the force to the side with no or less force, i.e., to the other side, thereby forming the sitting nest 304 at the front side with more force and gradually forming the sofa backrest and the sofa armrest near the rear side or side.

It is also worth mentioning that the peripheral side 303 of the multifunctional sofa bed 10 in the upright state is substantially a cylindrical or cylindrical structure, so that when it is pressed, the binding force of the peripheral side is substantially consistent, and therefore, the multifunctional sofa bed will not collapse excessively at the position where the force is applied, i.e. the user U will not feel an excessive sinking feeling. In other words, in the upright position 300, the multi-function sofa sleeper 10 has a better supporting force.

It is also worth mentioning that the multi-function sofa sleeper 10 is made of flexible material, which can be easily spread on the bottom surface for use, but is difficult to be formed into a three-dimensional state, and thus is in a three-dimensional turning state, which is required to provide a supporting force to the user at the bottom surface and the periphery by the function of the sofa, and the coupling assembly 13 is provided so that when the multifunctional sofa bed 100 is required to be unfolded, the coupling assembly 13 is in an open state, the multi-function sofa sleeper 10 can be unfolded with a free state, when it is needed to provide the three-dimensional support, the combination component 13 combines two sides thereof, so that the combination component can not be scattered under the action of pressure, and the three-dimensional support structure is maintained, it is not a naturally stacked three-dimensional shape, but a three-dimensional shape formed by the multifunctional sofa bed 10 being deformed by pressure under the constraint of the coupling assembly 13.

It is also worth mentioning that the volume of the particles filled in the multifunctional sofa bed 10 is smaller than the volume of the inner space 1001, when the multifunctional sofa bed 10 is erected, the filler 12 in the inner space 1001 of the multifunctional sofa bed 10 moves downward, and the upper portion of the inner space 1001 is not filled to be empty, so that the particles at a certain position can move to the surrounding space when the particles are under the action of pressure.

Optionally, the filler particles of the multifunctional sofa bed 10 are coarse particles with a single weight of 9-12g, and preferably, the filler particles of the multifunctional sofa bed 10 are coarse particles with a single weight of 11g and a diameter size of about 4 mm. Of course, in other embodiments, the filler particles may be selected from particles of other weights or size ranges, and the size of the particles does not limit the overall concept of the invention. It is worth mentioning that the filler particles under the gram weight can satisfy a better supporting effect under the condition that the overall weight of the multifunctional sofa bed is lighter. Preferably, in an embodiment of the present invention, the length of the main body 11 ranges from 1.7 to 1.9m, the width ranges from 0.7 to 0.9m, the weight of the main body is 10 to 12g of coarse particles, the total filling mass ranges from 1450g to 1650g, and at this ratio of size and filling amount, the multifunctional sofa bed 10 can better satisfy the use requirement between a plurality of states, such as better plane supporting effect when unfolded, and can provide better supporting effect when standing up, in other words, the size and filling ratio of the multifunctional sofa bed are related to the supporting requirement between a plurality of states, and the weight and total filling amount of the multifunctional sofa bed need to be balanced between the size and the supporting state.

Further, referring to fig. 3, the main body 11 of the multifunctional sofa bed 10 includes an inner bag 111 and an outer bag 112, and the outer bag 112 of the multifunctional sofa bed 10 is sleeved outside the inner bag 111. That is, the overall shapes of the inner bag 111 and the outer bag 112 are substantially identical.

The inner bag 111 includes an inner bag body 111 and forms the inner space 1001, and the outer bag 112 includes an outer bag body 1121 and has a receiving chamber 1002, and the inner bag body 111 is received in the receiving chamber 1002.

The outer bag 111 and the outer bag 112 are each an elongated square shape, and each form one of the inner space 1001 and a housing chamber 1002. In other words, the inner bag 111 and the outer bag 112 form the top surface and the bottom surface, respectively, and the inner space 1001 and the accommodation chamber 1002 are formed by being separated by the top surface and the bottom surface.

The inner bag 111 has two inner free edges 1051 and the outer bag 112 has two outer free edges 1052, and the inner free edges 1051 and the outer free edges 1052 correspond to each other and form the free edges 104 integrally. The inner bag 111 has two inner binding edges 1041, the outer bag 112 has two outer binding edges 1042, and the inner binding edges 1041 and the outer binding edges 1042 correspond to each other to form the binding edges 105.

The coupling assembly 13 is disposed at both outer coupling edges 1042 of the outer bag 112. Further, the coupling members 13 are respectively disposed at shorter opposite sides of the outer bag 112. When the user U needs to change the state of the multi-function sofa bed 10, it can be adjusted by operating the coupling assembly 13 of the outer bag 112, such as to couple the shorter sides of the outer bag 112 to each other.

The outer bag 112 has an access opening 1003 for allowing the inner bag 111 to enter and exit, that is, the access opening 1003 communicates the inner space 1001 of the outer bag 112 with the outside. The outer bag 112 includes a closing member 1122, and the closing member 1122 is disposed at the access 1003 to control the opening or closing of the access 1003. The closure member 1122 is illustratively, but not limited to, a zipper, buttons, cohesive fasteners, snaps, etc., and preferably the closure member 1122 is a zipper such that the access opening 1003 is completely closed without viewing the interior. In this embodiment of the invention, the access opening 103 is provided in one of the outer free edges 1052.

It should be noted that, in some embodiments, the outer bag 112 and the inner bag 111 are detachably disposed, and the outer bag 112 and the inner bag 111 are identical in size and shape, so that when the inner bag 111 is filled in the outer bag 112, the outer bag 112 is entirely spread, when two sides of the outer bag 112 are combined with each other, the outer bag 112 forms a closed ring, the inner bag 111 is correspondingly limited by the outer bag 112 to a corresponding state, that is, when the combination components 13 disposed on the outer bag 112 are combined with each other, two corresponding opposite sides of the inner bag 111 are also combined with each other, and although not directly fixedly combined, the two corresponding opposite sides of the inner bag 111 are also formed into a ring shape, that is, a support shape identical to the outer bag 112 is formed.

Further, the inner bag 111 has at least one spacing line 1112, the spacing line 1112 is disposed on the inner bag 1111, for example, the inner bag 1111 forms the spacing line 1112, and the spacing line 1112 divides the inner space 1001 into a plurality of sub-spaces 10011. The fillers 12 are respectively filled in the sub-spaces 10011.

Preferably, the inner bag 111 is provided with two spaced lines 1112, which are spaced to divide the inner space 1001 into three subspaces 10011, and the fillers 12 are respectively filled in the three subspaces 10011.

The subspaces 10011 may have the same or different volume sizes, i.e., the spacing lines 1112 may substantially bisect the inner space 1001 or may be otherwise spaced. Preferably, the spacing line 1112 equally divides the inner space 1001 such that the filling amount in the sub-space 10011 is substantially the same, i.e., provides substantially uniform support conditions.

It is worth mentioning that the arrangement of the spacing lines 1112 enables the filling space to be divided into smaller spaces by larger spaces, thereby enabling the filling particles to move in the smaller spaces without causing serious accumulation of the filling due to the movement of the large spaces, and thus deteriorating the user experience.

It is also worth mentioning that the spacing lines 1112 are arranged along the width direction, which matches the supporting force requirements of different deformation states of the multifunctional sofa bed 10, for example, in the unfolded state 100 of the multifunctional sofa bed 10, the multifunctional sofa bed 10 mainly needs to provide a planar supporting function, that is, to provide a planar support with a certain thickness as flat as possible, in this case, on one hand, it needs to consider that the fillers 12 are not piled up due to the operation manner when the multifunctional sofa bed is unfolded for use, for example, when the multifunctional sofa bed is randomly unfolded, thereby increasing the inconvenience of use; on the other hand, it is necessary to consider whether the distribution of particles in each of the subspaces 10011 can make the supporting surface formed by a plurality of the subspaces 10011 substantially flat. In the coupled state 200 of the multi-purpose sofa bed 10, i.e., the state of forming a seat cushion, it is also necessary to consider the problem of avoiding the pile-up, so that the user U can form the coupled state 200 only by operating the coupling assembly 13 without the need to perform the flatness or the position adjustment of the filler 12 again. In the upright position 300, i.e. the position in which a sofa seat can be provided, it is necessary to take into account the provision of a stable, balanced supporting force in the vertical direction, i.e. to arrange as much as possible a substantially uniform amount of the filling 12 in the vertical direction along one circumference of the roll, and on the other hand it is necessary to produce a deformation in the height direction, i.e. to be able to form the seat pocket 304 under the influence of an external force. The unfolded state 100, the combined state 200 and the erected state 300 are all based on the same form change, so that the requirements in the different states need to be met simultaneously, and the spacing lines 1112 arranged along the width direction of the unfolded state 100 can better meet the requirements in the different states.

It is also worth mentioning that the inner bag 111 and the outer bag 112 cooperate with each other such that the inner bag 111 meets the main support requirements, while the outer bag 112 makes the outer whole look without obvious gaps, thereby enhancing the aesthetic appearance of the whole, and the outer bag 112 can be adapted to various personalized settings, such as setting a distinctive color, such as yellow and fresh green, like mango work, or can be adapted to various patterns, such as cartoon characters, or can be provided with patterns on the outer bag in a customized manner according to the customer requirements. Of course, other different shapes may be provided, and the above is merely exemplary and not limiting.

In other embodiments of the present invention, some auxiliary accessories may be further disposed on the outer bag 112, such as a pocket disposed on the outer bag 112, or some small protrusions for massaging may be disposed, or a layer of material for adjusting temperature feeling, such as temperature feeling or cool feeling material, may be attached on the outer bag 112.

It is also worth mentioning that in another embodiment of the present invention, the outer bag 112 may not be provided, i.e. the inner bag 111 is directly exposed, although there are some disadvantages compared to the way the outer bag 112 is provided, but such an embodiment is not excluded by the present invention. In another embodiment, the inner bag 111 may not be provided with the spacing lines 1112, that is, the inner space 1001 of the inner bag 111 is not spaced to form the sub-space 10011, although there is a disadvantage in comparison with the embodiment in which the spacing lines 1112 are provided, but the present invention does not exclude such an embodiment.
