Description

Technical Field

[0001] The present application relates to the technical field of furniture, and in particular to a sofa bed. Background Art

[0002] People usually place sofas and beds at home, but placing sofas and beds separately will take up a lot of space, which is not friendly to small-sized houses, and buying sofas and beds separately will also incur a lot of expenses, which is not friendly to users who rent houses. Therefore, sofa beds came into being. Sofa beds are multifunctional furniture that can be used as both sofas and beds. They can effectively reduce the occupied space, meet the needs of users who need both beds and sofas, and reduce the economic burden of users.

[0003] A sofa bed is proposed in the related art, comprising a sofa seat, a forward-moving sofa cushion arranged at the middle of the top of the sofa seat, and a folding sofa backrest arranged at the rear end of the sofa seat, a rotatable flip bed board is installed at the rear end of the sofa backrest, the flip bed board is connected to the sofa seat by a hinge, and a bracket is arranged at the end of the flip bed board away from the sofa seat. When the sofa bed is used as a sofa, the flip bed board is in a vertical state, the sofa backrest is also in a vertical state, and the forward-moving sofa cushion is located on the top of the sofa seat; when the sofa bed is used as a bed, the forward-moving sofa cushion moves forward, the sofa backrest turns from a vertical state to a horizontal state, and is in the same horizontal plane as the forward-moving sofa cushion, and then the flip bed board is turned from a vertical state to a horizontal state, and the end of the flip bed board close to the sofa seat is located above the forward-moving sofa cushion and the sofa backrest, and the flip bed board is supported by the bed board bracket and the sofa backrest. A sofa bed of this structure has some disadvantages: when the sofa bed is used as a sofa, the flip bed board is in a vertical state, and the length of the flip bed board is generally greater than the average height of an adult, so the height of the flip bed board in the vertical state is too high, which looks bad and has certain safety hazards; when the sofa bed is used as a bed, the flip bed board needs to be turned from a vertical state to a horizontal state, which is difficult and laborious to operate.

If described, "the second" is only used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0034] In the description of this application, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in this application based on the specific content of the technical solution.

[0035] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0036] See also Figure 1 and Figure 2 The embodiment of the present application provides a sofa bed, which can improve space utilization, reduce the economic burden of users, and has low operating difficulty, easy use and high safety.

[0037] The sofa bed includes a seat body 300, a first panel 100 and a support body 200. The seat body 300 is formed with a seat surface 311. The support body 200 is used to support the first panel 100. The support body 200 is rotatably connected to the seat body 300. By rotating the support body 200 and moving the first panel 100, the sofa bed can be switched between a sofa mode and a bed mode. Figure 2 When the sofa bed is in sofa mode, the support body 200 is folded and placed on the seat body 300; see Figure 1 When the sofa bed is in bed mode, the support body 200 is unfolded and placed on the ground, the first panel 100 is placed on the support body 200 , and the upper surface of the first panel 100 is coplanar with the seat surface 311 .

[0038] Optionally, the seat surface 311 is parallel to the horizontal plane. When the sofa bed is in bed mode, the upper surface of the first panel 100 is coplanar with the seat surface 311 and is on the same horizontal plane, forming a bed surface together.

[0039] Of course, the seat surface 311 can also be tilted. When the sofa bed is in bed mode, the bed surface formed by the upper surface of the first panel 100 and the seat surface 311 is an inclined bed surface, which will not be elaborated here.

[0040] It is understandable that the first panel 100 can be directly rotatably connected to the base 300, or can be indirectly connected to the base 300 through the support body 200. The first panel 100 can be detachably connected to the support body 200, or can be integrally formed with the support body 200.

[0041] For example, the first panel 100 is directly rotatably connected to the base 300 and is detachably connected to the support body 200. It is understood that in this case, the first panel 100 and the support body 200 can be rotated separately. Figure 2 When the sofa bed is to be used as a sofa, the support body 200 can be folded and placed on the seat body 300 by rotating the support body 200, and the first panel 100 can be placed on the seat surface 311 by rotating the first panel 100, so that the sofa bed can be formed into a sofa; see Figure 1 When the sofa bed is to be used as a bed, the support body 200 can be unfolded and placed on the ground by rotating the support body 200 in the opposite direction, and the first panel 100 can be placed on the support body 200 by rotating the first panel 100 in the opposite direction, thereby enabling the sofa bed to form a bed.

[0042] For another example, the first panel 100 is directly rotatably connected to the base 300 and is integrally formed with the support body 200. It is understandable that the first panel 100 and the support body 200 in this case can rotate together. When the first panel 100 and the support body 200 are integrally formed, in order to make the first panel 100 close to the seat surface 311 when the support body 200 is folded and placed on the base 300, and to prevent the first panel 100 from being deformed by pressure, the first panel 100 can be coplanar with the top surface of the support body 200, and when the support body 200 is folded, the first panel 100 and the support body 200 can be placed together on the seat surface 311. Of course, the support body 200 may also be provided with a convex structure (such as a frame) around the first panel 100, and the seat body 300 may be provided with a corresponding groove for the convex structure to be embedded, so that when the support body 200 is folded and placed on the seat body 300, the first panel 100 can be in close contact with the seat surface 311, preventing the first panel 100 from being easily deformed when the sofa bed is used as a sofa. When the sofa bed is to be used as a sofa, the support body 200 is rotated so that the support body 200 can be folded and placed on the seat body 300; when the sofa bed is to be used as a bed, the support body 200 is rotated in the opposite direction so that the support body 200 can be unfolded and placed on the ground.

[0043] Of course, the first panel 100 may not be directly connected to the base 300, but may be integrally formed with the support body 200, and indirectly rotatably connected to the base 300 through the support body 200. In this case, a small gap may be left between the first panel 100 and the base 300 so that the first panel 100 can rotate with the support body 200. No further details will be given here.

[0044] Alternatively, the first panel 100 is detachably connected to the support body 200, and is indirectly connected to the seat 300 through the support body 200. When the sofa bed is to be used as a sofa, the support body 200 is rotated so that the support body 200 can be folded and placed on the seat 300, and the first panel 100 can be placed on the seat surface 311 or stored, so that the sofa bed forms a sofa; when the sofa bed is to be used as a bed, the support body 200 is rotated in the opposite direction so that the support body 200 can be unfolded and placed on the ground, and the first panel 100 is placed on the support body 200, and the side edge of the first panel 100 close to the seat 300 is closely attached to the seat 300, so that the sofa bed forms a seamless bed.

[0045] The following description will be made by taking “the first panel 100 is rotatably connected to the base body 300 and is detachably connected to the support body 200” as an example.

[0046] Exemplarily, the sofa bed further includes a first rotatable connection member 400 , and the first panel 100 is rotatably connected to the seat body 300 via the first rotatable connection member 400 .

[0047] It is understandable that one or more first rotatable connecting members 400 may be provided. Figure 3 There are three first rotatable connecting members 400 , and the three first rotatable connecting members 400 are arranged at intervals along the length direction of the first panel 100 .

[0048] Optionally, the seat body 300 includes a second panel 310, and the upper surface of the second panel 310 forms a seat surface 311. Figure 3 The first panel 100 has a first connecting edge 110 , and the second panel 310 has a second connecting edge 3111 . The first connecting edge 110 is rotatably connected to the second connecting edge 3111 via a first rotatable connecting member 400 .

[0049] Alternatively, see Figure 3, the first panel 100 and the second panel 310 are both rectangular panels, the first connecting edge 110 is a long side of the first panel 100, and the second connecting edge 3111 is a long side of the second panel 310. The length of the second connecting edge 3111 may be greater than or equal to the length of the first connecting edge 110, and the width of the second panel 310 may be greater than or equal to the width of the first panel 100. Optionally, the length of the second connecting edge 3111 is equal to the length of the first connecting edge 110, and the width of the second panel 310 is equal to the width of the first panel 100.

[0050] Optionally, the first rotatable connecting member 400 includes a first connecting part 410 and a second connecting part 420, a first groove (not shown in the drawings) is opened on the first panel 100, the first connecting part 410 is installed in the first groove, a second groove (not shown in the drawings) is opened on the base body 300, the second connecting part 420 is installed in the second groove, and the first connecting part 410 is rotatably connected to the second connecting part 420.

[0051] Optionally, the second groove is formed on the upper surface of the second panel 310 (i.e., the seat surface 311), and the first groove is formed on the surface of the first panel 100 on the side close to the seat surface 311 (not shown in the drawings). This structural arrangement can effectively prevent the first rotatable connector 400 from protruding when the sofa bed is used as a bed, which is conducive to improving the comfort of the sofa bed when used as a bed; at the same time, when the sofa bed is used as a sofa, the first panel 100 can be close to the seat surface 311, which is conducive to preventing the first panel 100 from being deformed under the action of pressure.

[0052] Optionally, the first rotatable connecting member 400 may be a hinge, so that the first panel 100 can rotate within an angle range of 0° to 180°. Figure 4 Schematic diagram of the first panel 100 rotating 180° and being in close contact with the upper surface (i.e., the seat surface 311) of the second panel 310. Figure 3 and Figure 4 The parent-child hinge includes a child leaf, a parent leaf and a hinge shaft 430. The first connecting part 410 is a child leaf, the second connecting part 420 is a parent leaf, the first connecting part 410 and the second connecting part 420 are both rotatably connected to the hinge shaft 430, and the second connecting part 420 is provided with a third groove 421 for the first connecting part 410 to be inserted. Optionally, the three first rotatable connecting members 400 can share one hinge shaft 430.

[0053] Of course, the first connection portion 410 may also be a main page, and the second connection portion 420 may also be a sub-page, which will not be elaborated herein.

[0054] Even if the grooves are not provided on the first panel 100 and the second panel 310, the use of the parent-child hinge can also make the first panel 100 close to the seat surface 311 when folded and placed on the seat surface 311, which is helpful to prevent the first panel 100 from being deformed under the action of pressure. Although the child and parent panels will protrude slightly when the first panel 100 is unfolded, when the sofa bed in the present application is used as a bed, a mattress can be placed on the first panel 100 and the second panel 310, thereby improving the comfort of the sofa bed when used as a bed.

[0055] Optionally, the support body 200 includes a frame and a support member 220, the frame is used to place the first panel 100, and the support member 220 is foldably arranged on a side of the frame away from the first panel 100 (see Figure 5 ). When the sofa bed is used as a sofa, the frame can be folded and placed on the seat body 300 and can be used as an armrest of the sofa.

[0056] Of course, the support body 200 can also be composed of a frame, and when the support body 200 is unfolded, the side of the frame away from the first panel 100 can be directly placed on the ground. However, this will increase the weight of the support body 200 to a certain extent, which is not conducive to the user turning over the support body 200.

[0057] For example, see Figure 5 The frame includes two first frames 211 and one second frame 212 . The two first frames 211 correspond to two side edges of the first panel 100 adjacent to the first connecting edge 110 , and the second frame 212 corresponds to a side edge of the first panel 100 away from the first connecting edge 110 .

[0058] Optionally, the support member 220 is a support foot, and two support feet are provided. The two support feet are foldably provided at two ends of the second frame 212 .

[0059] Alternatively, see Figure 5 and Figure 6 The second frame 212 is provided with two receiving grooves 2122 (see Figure 6 When the support body 200 is folded, the support leg is folded and placed in the receiving groove 2122. When the support body 200 is unfolded, the support leg rotates to a state perpendicular to the second frame 212 to provide support force.

[0060] Of course, the supporting feet and the receiving slots 2122 can also be set to four, six or other numbers. It is understandable that the number of supporting feet and receiving slots 2122 is the same and corresponds one to one. The specific number of supporting feet and receiving slots 2122 can be set according to actual needs and is not specifically limited here.

[0061] Alternatively, see Figure 7 The support body 200 is provided with a sink 2121 to receive the first panel 100. Optionally, the sink 2121 is provided on the inner side of the second frame 212. When the first panel 100 is unfolded, the side of the first panel 100 away from the first connecting edge 110 can be placed flat on the bottom wall of the sink 2121.

[0062] Optional, see Figure 5 , the second panel 310 is provided with a third frame 320 at two sides adjacent to the second connecting edge 3111, and the two sides adjacent to the second connecting edge 3111 of the second panel 310 are respectively connected to the corresponding third frames 320, and the bottom of the third frame 320 is placed on the ground so that the third frame 320 can support the second panel 310. Optionally, the second panel 310 can be integrally formed with the two third frames 320. Optionally, the third frame 320 protrudes from the surface where the second panel 310 is located. See Figure 6 When the sofa bed is used as a sofa, the two first frames 211 of the frame can be folded and placed on the third frame 320 and can be used as armrests of the sofa.

[0063] Alternatively, see Figure 6 The two third frames 320 are both provided with support columns 322 on one side close to the second connection edge 3111 of the second panel 310 to support the frame when unfolded. Optionally, the support columns 322 are integrally formed with the third frames 320.

[0064] In some embodiments, see Figure 5 The sofa bed further comprises a second rotatable connecting member 500, through which the supporting body 200 is rotatably connected to the seat body 300, and the second rotatable connecting member 500 is retractably arranged.

[0065] Furthermore, the second rotatable connecting member 500 includes a first rotating shaft 510, a second rotating shaft 520 and a telescopic portion 540. A first opening groove 2111 is provided on the support body 200, and the first rotating shaft 510 is rotatably installed in the first opening groove 2111. A second opening groove 321 is provided on the base body 300, and the second rotating shaft 520 is rotatably installed in the second opening groove 321. One end of the telescopic portion 540 is fixedly connected to the first rotating shaft 510, and the end of the telescopic portion 540 away from the first rotating shaft 510 is fixedly connected to the second rotating shaft 520.

[0066] Alternatively, see Figure 5 , one end of the two first frames 211 close to the first connecting edge 110 is rotatably connected to the corresponding third frame 320 through the second rotatable connecting member 500. Figure 5 and Figure 8The first frame 211 has a first opening slot 2111 at one end close to the first connecting edge 110. The first opening slot 2111 has a first bottom wall 21111 and two opposite first side walls 21112. The two ends of the first rotating shaft 510 are rotatably connected to the two first side walls 21112 of the first opening slot 2111 through bearings 530. The third frame 320 has a second opening slot 321. The second opening slot 321 has a second bottom wall 3211 and two opposite second side walls 3212. The two ends of the second rotating shaft 520 are rotatably connected to the two second side walls 3212 of the second opening slot 321 through bearings 530.

[0067] Optionally, an arc portion is provided at one end of the first side wall 21112 of the first opening slot 2111 away from the first bottom wall 21111, and an arc portion is also provided at one end of the second side wall 3212 of the second opening slot 321 away from the second bottom wall 3211, and when the support body 200 is unfolded and placed on the ground, the first side wall 21112 is tangent to the second side wall 3212. This structural setting is conducive to the rotation of the support body 200.

[0068] It is understandable that in some cases, if the length of the connection portion (non-retractable) between the first rotating shaft 510 and the second rotating shaft 520 is too long, it may cause a gap when the support body 200 is folded and placed on the base 300, making the support body 200 easy to shake. Therefore, by providing a retractable portion 540 between the first rotating shaft 510 and the second rotating shaft 520, the distance between the first rotating shaft 510 and the second rotating shaft 520 can be properly adjusted, that is, when the support body 200 is unfolded and placed on the ground, the retractable portion 540 can be extended ( Fig. 9 Schematic diagram showing the structure of the second rotatable connecting member 500 when the telescopic portion 540 is extended); when the support body 200 is folded and placed on the seat body 300, the telescopic portion 540 can be shortened ( Fig.10 Schematic diagram of the structure of the second rotatable connecting member 500 when the telescopic portion 540 is shortened), so that when the support body 200 is folded and placed on the seat body 300, it can be close to the seat body 300 to prevent the support body 200 from shaking, and at the same time does not affect the rotation of the support body 200.

[0069] Alternatively, see Figure 8 and Fig. 9 The telescopic portion 540 includes a first portion 541 and a second portion 542, wherein the first portion 541 is movably connected to the second portion 542, so that the first portion 541 can move along the length direction of the second portion 542, thereby adjusting the length of the telescopic portion 540. Optionally, the first portion 541 is sleeved outside the second portion 542, and one end of the first portion 541 away from the second portion 542 is fixedly connected to the first rotating shaft 510, and one end of the second portion 542 away from the first portion 541 is fixedly connected to the second rotating shaft 520.

[0070] It is understandable that a limiting portion (not shown in the drawings) may be provided on the first portion 541 or the second portion 542 to prevent the first portion 541 from coming off the second portion 542 when the first portion 541 moves relatively along the length direction of the second portion 542. Optionally, the limiting portion may be a limiting groove. Exemplarily, a limiting groove is provided on the second portion 542, and the limiting groove extends along the length direction of the second portion 542. A limiting block extending into the limiting groove is provided on the first portion 541, and the limiting block can slide in the limiting groove along the length direction of the limiting groove. The side wall of the limiting groove close to the first portion 541 can abut against the limiting block to limit the limiting block, thereby preventing the first portion 541 from coming off the second portion 542. Of course, the limiting portion may also adopt other limiting structures, which are not specifically limited here.

[0071] Optionally, at least one third connection portion 5411 is provided on the first portion 541 , and at least one fourth connection portion 5421 is provided on the second portion 542 . The fourth connection portion 5421 can be detachably connected to the third connection portion 5411 to fix the length of the telescopic portion 540 .

[0072] It can be understood that one or more third connection parts 5411 can be provided. When the third connection parts 5411 are provided in plurality, the plurality of third connection parts 5411 are spaced apart along the length direction of the first part 541. One or more fourth connection parts 5421 can also be provided. When the fourth connection parts 5421 are also provided in plurality, the plurality of fourth connection parts 5421 are spaced apart along the length direction of the second part 542. The specific number of the third connection parts 5411 and the fourth connection parts 5421 can be set according to actual needs.

[0073] For example, see Fig. 9 , one third connection part 5411 is provided, and one fourth connection part 5421 is also provided. The third connection part 5411 and the fourth connection part 5421 can be connected by snap-fit, bolted or other detachable connection methods, which are not specifically limited here.

[0074] It can be understood that when the third connecting portion 5411 is connected to the fourth connecting portion 5421, the telescopic portion 540 is in a shortened state (see Fig.10), and at this time, the length of the telescopic portion 540 can just meet the requirement that the support body 200 folded and placed on the base 300 is tightly attached to the base 300. That is to say, when the support body 200 is folded and placed on the base 300, the third connection portion 5411 and the fourth connection portion 5421 can be connected together to further prevent the support body 200 from shaking. When the third connection portion 5411 and the fourth connection portion 5421 are separated, the telescopic portion 540 can be extended. That is to say, when the support body 200 needs to be unfolded, the third connection portion 5411 and the fourth connection portion 5421 can be separated.

[0075] In some embodiments, the seat body 300 is formed with a storage cavity 331 below the seat surface 311. When the sofa bed is used as a sofa, items such as quilts and pillows can be stored in the storage cavity 331, which can further improve space utilization.

[0076] Alternatively, see Fig.11 The base body 300 is provided with a drawer 330 below the second panel 310, a storage cavity 331 is formed in the drawer 330, and a drawer portion (not shown in the drawings) may be provided on the outer surface of the drawer 330 to facilitate drawing the drawer 330. Optionally, the drawer portion may be a drawer portion such as a groove or a handle, which is not specifically limited here.

[0077] Optionally, the second panel 310 is rotatable, and the storage cavity 331 can be opened or closed by rotating the second panel 310. Optionally, the second panel 310 can be rotatably connected to the first panel 100, or can be rotatably connected to the third frame 320, which is not specifically limited here.

[0078] Of course, the base body 300 may also be provided with a storage box under the second panel 310 , and a storage cavity 331 is formed in the storage box, which will not be elaborated herein.

[0079] In some embodiments, see Figure 5 or Fig.11 The sofa bed further includes a headboard 600, which is disposed on a side of the seat body 300 away from the second connecting edge 3111 of the second panel 310. Optionally, the headboard 600 can be integrally formed with the two third frames 320 of the seat body 300. It is understandable that when the sofa bed is used as a sofa, the headboard 600 can be used as a backrest.

[0080] Other structures and operations of the sofa bed according to the embodiment of the present application are known to those skilled in the art and will not be described in detail here.

[0081] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
