Description

Technical Field

[0001] This application relates to the technical field of sofa beds, and in particular to a multifunctional sofa bed. Background Technology

[0002] RVs, also known as "homes on wheels," combine the functions of a "house" and a "vehicle." However, the living space inside an RV is generally much smaller than the normal living space for humans. Therefore, how to efficiently utilize RV space has become an urgent problem for major RV manufacturers.

[0003] In related technologies, corresponding improvements are made to the sofas in RVs, turning them into foldable or flip-up sofas. By relying on the sofa back or folded sofa cushions, the sofa bed can be used as both a bed and a sofa. However, in the process of turning a foldable or flip-up sofa into a bed, the weight of the backrest or mattress and the folding or flipping mechanism itself is too heavy, which causes too much inconvenience for the user. Summary of the Invention

[0004] To improve the ease of operation of the sofa bed during the transformation process, this application provides a multifunctional sofa bed.

[0005] This application provides a multifunctional sofa bed, which adopts the following technical solution:

[0006] Two sofas are arranged opposite each other, and a height-adjustable table is provided between the sofas; the height-adjustable table includes a lifting platform and a base plate slidably disposed on the top of the lifting platform, the lifting platform includes a base, a lifting column rotatably connected to the base, and a sliding assembly connected to the base plate;

[0007] A mattress is provided on the side of the base plate away from the lifting platform, and a table is provided on the side of the mattress away from the base plate, with the table covering the mattress.

[0008] The tabletop includes two splicing panels, with the opposite sides of the two splicing panels rotatably connected to the base plate.

[0009] By adopting the above technical solution, when the sofa bed is needed, first raise the base plate above the sofa, and rotate the lifting platform so that the base plate is perpendicular to the sofa; then adjust the lifting column to a suitable height so that the mattress is level with the sofa; rotate the two connecting panels so that the two connecting panels are perpendicular to the mattress. At this time, the mattress and the two sofas form a sofa bed for the user to rest, and the two connecting panels can also be used as guardrails for the sofa bed; in the process of assembling the lifting platform and the sofa into a sofa bed, there is no need to move or fold the mattress, which simplifies the operation steps of the sofa bed transformation process and improves the ease of sofa bed transformation.

[0010] When the sofa bed is not needed, the two panels can be placed over the mattress, and the lift-up table can be used as a regular table. One end of the base plate is connected to a sliding component, allowing the user to slide the base plate to different positions as needed. The tabletop on the base plate also slides along with the base plate. Because the base and the lift-up column are rotatably connected, the tabletop can rotate.

[0011] Optionally, the sliding assembly includes a longitudinal slide rod fixed to one end of the lifting column, two longitudinal slide sleeves respectively sleeved at both ends of the longitudinal slide rod, two transverse slide rods parallel to each other and spaced apart at the end of the base plate away from the lifting column, and a transverse slide sleeve sleeved on the outer wall of the transverse slide rod; the transverse slide rod is perpendicular to the longitudinal slide rod, and the end of the transverse slide sleeve near the longitudinal slide rod is connected to the longitudinal slide sleeve.

[0012] By adopting the above technical solution, two longitudinal sliding sleeves slide at both ends of the longitudinal sliding rod, and the ends of the two longitudinal sliding sleeves away from the longitudinal sliding rod are connected to transverse sliding sleeves, which are fitted onto the transverse sliding rods; when the base plate is pushed longitudinally, the transverse sliding sleeves will drive the longitudinal sliding sleeves to slide along the longitudinal sliding rods; when the base plate is pushed transversely, the transverse sliding rods move along the transverse sliding sleeves; when the base plate moves on its horizontal plane, the lifting column can still provide stable support for the base plate.

[0013] Optionally, the lifting column includes several support sleeves of different diameters, which are slidably connected in sequence, and each support sleeve is provided with a positioning element for fixing its own position.

[0014] By adopting the above technical solution, the height of the lifting column is adjusted by sequentially fitted support sleeves, and the positioning parts on each support sleeve are used to fix the position of the support sleeve inside another support sleeve, reducing the occurrence of the lifting column dropping in height when the load on the top of the lifting column is too large.

[0015] Optionally, the base plate is a rectangular plate, and a connecting block is fixed at each of the four corners. A pivot is provided at one end of the splicing plate near the connecting block, and the two ends of the pivot are respectively inserted into the two connecting blocks located on the same side, and the pivot can rotate around its own axis.

[0016] By adopting the above technical solution, connecting blocks are set at the four top corners of the base plate, and the rotating shaft on the splicing plate passes through the connecting blocks to realize the rotational connection between the splicing plate and the base plate.

[0017] Optionally, one of the splicing plates has a connector strip at one end away from the pivot, and the other splicing plate has a connector groove for accommodating the connector strip; the connecting block has a sliding groove, and the end of the pivot slides in the sliding groove, with the sliding direction being towards or away from the adjacent connecting block; the sliding groove has an abutment for pressing against the pivot, and the abutment can move along the sliding groove.

[0018] By adopting the above technical solution, the insertion strip set at one end of one splicing plate is inserted into the insertion groove of another splicing plate, which enhances the connection stability between the two splicing plates; it also enhances the sealing of the connection between the two splicing plates, so that when the connecting block is splashed with liquid, the liquid is not easy to flow into the mattress below the splicing plate through the connection between the two splicing plates.

[0019] When it is necessary to rotate the two panels, push the two panels to move them away from each other. The abutment on one side of the pivot moves with the pivot in a direction away from the mattress, causing the insert strip to disengage from the insert groove and the two panels to separate. Then the abutment moves towards the mattress, and the pivot is abutted between the inner wall of the slide and the abutment. When the panel rotates to be perpendicular to the mattress, the abutment and the inner wall of the slide prevent the panel from rotating again.

[0020] Optionally, the inner wall of the slide is provided with a through groove for the splicing plate and the pivot to slide out, and the splicing plate is provided with a storage groove at one end near the mattress, and a table leg is provided in the storage groove; one end of the table leg is rotatably connected to the inner wall of the storage groove, and the other end is detachably connected to the inner wall of the storage groove.

[0021] By adopting the above technical solution, the splicing panel is pulled away from the mattress. When the pivot moves to align with the through groove, the splicing panel is rotated until its side is parallel to the through groove, and then the splicing panel is pushed away from the mattress. When the pivot at one end of the splicing panel is detached from the connecting block, while the pivot at the other end remains connected to the connecting block, one end of the table leg is removed from the storage groove. Rotating the table leg provides support for the end of the splicing panel away from the mattress, thus achieving the effect of expanding the height-adjustable tabletop.

[0022] Optionally, one end of the table leg is rotatably connected to the splicing plate, and the other end is provided with a rotating rod assembly; the rotating rod assembly includes two rotating rods arranged opposite each other, and the side wall of the storage groove is provided with a receiving groove for the rotating rods to slide, and the side wall of the receiving groove is provided with a mounting hole, through which the rotating rods can pass out of the receiving groove.

[0023] By adopting the above technical solution, the rotating rod assembly slides within the receiving groove, achieving a detachable connection between one end of the table leg and the side wall of the storage groove; the connecting part of the two rotating rods passes through the table leg, fixing the table leg within the storage groove; the positioning part of the sliding rotating rod disconnects the rotating part from the table leg, and then the two rotating rods are removed from the mounting hole, thereby achieving a rotating connection between the table leg and the base plate; rotating the table leg away from the base plate provides support for the end of the splicing panel away from the base plate.

[0024] Optionally, the table leg includes two detachably connected support columns; one end of the support column is provided with a snap-fit ​​block, and the other support column is provided with a snap-fit ​​groove for the snap-fit ​​block to snap into; the rotating rod includes a connecting part and a positioning part, wherein the connecting part is cylindrical and the positioning part is rectangular.

[0025] When the rotating rod is used to fix a support column and a splicing plate, one end of the support column is sleeved outside the connecting part;

[0026] The snap-fit ​​block has a through hole for the positioning part to pass through, and the snap-fit ​​groove sidewall has a clearance hole for the positioning part to pass through; a magnet is provided at the end of the connecting part away from the positioning part.

[0027] By adopting the above technical solution, when the table legs need to provide support for the end of the splicing panel away from the base plate, the rotating rod taken out from the receiving groove is inserted into the through hole through the clearance hole, and the two rotating rods are connected by magnets on the connecting part; part of the rectangular block positioning part is located in the through hole, and the other part is located in the clearance hole, so that the two support columns are fixedly connected; when the user removes it from the connecting block, the rotating rod assembly is removed from the snap-fit ​​block and installed in the receiving groove; the rotating rod is slid so that the connecting part passes through the table leg; since the connecting part is cylindrical, the opposite ends of the two support columns are rotatably connected to the base plate at this time, and the two support columns are rotated away from the base plate so that the two support columns provide support for the splicing panel. When the height-adjustable table and two sofas are combined to form a sofa bed, the splicing panel can also be used as a bed desk, providing users with more convenient options.

[0028] Optionally, a push-pull rod is provided at the end of the positioning part away from the connecting part, and the push-pull rod is arranged perpendicular to the positioning part.

[0029] By adopting the above technical solution, the push-pull rod is designed to facilitate the user's sliding rotation rod, and also to facilitate the user's insertion or removal of the rotation rod into the receiving slot along the mounting hole.

[0030] In summary, this application includes at least one of the following beneficial effects of a multifunctional sofa bed:

[0031] 1. Install a height-adjustable table between sofas. The table is equipped with two connecting panels, and a mattress is placed under the panels. Rotate the table 90° and adjust it until the mattress and sofa are at the same height. Then, rotate the two panels away from the mattress, and the mattress and sofa will transform into a sofa bed for the user to rest.

[0032] 2. The two splicing panels can slide off the mattress, so that only one end of the pivot is connected to the connecting block on the base plate. The storage groove of the splicing panel is equipped with table legs, and one end of the table legs is detachably connected to the splicing panel. Separate one end of the table legs from the splicing panel and rotate the table legs away from the splicing panel so that the table legs provide support for the end of the splicing panel away from the splicing panel, thereby expanding the desktop area of ​​the height-adjustable table.

[0033] 3. The table legs include two detachable support columns, and the opposite ends of the support columns can be connected to the splicing panel. After the splicing panel is separated from the mattress, the two support columns on the splicing panel can provide support for both ends of the splicing panel, so that after the sofa and the lift table are combined to form a sofa bed, the splicing panel can be used as a desk on the bed for the user.

The end of the connecting sleeve near the base plate 3 is fixedly connected to the base plate 3, and the transverse sliding sleeve 44 slides on the outer wall of the transverse sliding rod 43. The transverse sliding rods 43 are arranged perpendicular to the longitudinal sliding rods 41, and the end of the transverse sliding sleeve 44 near the longitudinal sliding rod 41 is connected to the longitudinal sliding sleeve 42.

[0049] The sliding component 4 and the lifting column 21 enable the base plate 3 to be height-adjustable and horizontally adjustable to meet the different needs of users.

[0050] Reference Figure 1 and Figure 2 A mattress 5 is fixed to one end of the base plate 3 away from the lifting platform 2. A table 6 is provided at one end of the mattress 5 away from the base plate 3, and the table 6 covers the mattress 5. The table 6 includes two splicing plates 61, and the opposite ends of the two splicing plates 61 are rotatably connected to the base plate 3.

[0051] Reference Figure 1 and Figure 4 The base plate 3 is specifically set as a rectangular plate, and a connecting block 31 is fixed at each of the four top corners. A rotating shaft 611 is fixed through one end of the splicing plate 61 near the connecting block 31, and the two ends of the rotating shaft 611 are respectively inserted into the two connecting blocks 31 located on the same side.

[0052] Reference Figure 5 and Figure 6In order to improve the connection stability between the two splicing plates 61 and improve the overall integrity of the tabletop 6, a plug strip 612 is fixed at one end of one splicing plate 61 away from the connecting block 31, and a plug groove 613 is provided on the other splicing plate 61; a long strip-shaped sliding groove 311 is provided on the connecting block 31, and the end of the rotating shaft 611 slides in the sliding groove 311.

[0053] The two splicing panels 61 are moved in opposite directions so that they are on the same horizontal plane. Then the two splicing panels 61 are moved towards each other so that the connector strip 612 is inserted into the connector slot 613, thereby connecting the two splicing panels 61.

[0054] Reference Figure 5 and Figure 6 To reduce the possibility of the connector strip 612 disengaging from the connector groove 613 after the two splicing plates 61 are connected, an abutment 9 is slidably provided at the end of the rotating shaft 611 away from the connector strip 612, and the abutment 9 moves along the slide groove 311. The abutment 9 includes an abutment plate 92 near one end of the rotating shaft 611, and guide pieces 91 fixed on both sides of the abutment plate 92, and the two guide pieces 91 slide on the opposite outer walls of the connecting block 31 respectively; a spring 93 is provided between the two guide pieces 91, one end of the spring 93 is fixedly connected to the inner wall of the slide groove 311, and the other end is fixed to the abutment plate 92.

[0055] When the end of the rotating shaft 611 slides in the groove 311, the abutment 9 moves together with the rotating shaft 611. When the rotating shaft 611 stops sliding, under the action of the spring 93 inside the abutment 9, the abutment 9 moves toward the rotating shaft 611. The rotating shaft 611 is clamped between the abutment 9 and the inner wall of the groove 311, thereby reducing the possibility of the rotating shaft 611 moving again.

[0056] Reference Figure 1 Rotate the base plate 3 by 90° and adjust the lifting column 21 so that the mattress 5 and the sofa 1 are on the same horizontal plane; then push the two splicing panels 61 to move away from each other to disconnect the connection between the two splicing panels 61, rotate the two splicing panels 61 away from the mattress 5, and the mattress 5 and the sofas 1 on both sides form a sofa bed for the user to rest; the two splicing panels 61 can also be rotated to be perpendicular to the mattress 5 and used as a guardrail, which can also provide the user with some privacy.

[0057] Reference Figure 4 and Figure 5A through groove 312 is provided on the inner side wall of the end of the slide groove 311 away from the mattress 5, through which the splicing plate 61 passes. In this embodiment, the through groove 312 is set perpendicular to the slide groove 311. A storage groove 62 is provided on the end of the splicing plate 61 near the mattress 5, and a table leg is provided in the storage groove 62. A connecting rod 614 is provided through one end of the table leg, and the two ends of the connecting rod 614 are fixedly connected to the two inner side walls opposite to the storage groove 62. A set of rotating rods 8 is provided through the other end of the table leg, and the set of rotating rods 8 is detachably connected to the table leg, thereby realizing the detachable connection between one end of the table leg and the splicing plate 61.

[0058] Reference Figure 7 and Figure 8 The rotating rod group 8 includes two rotating rods 8 arranged opposite each other. The rotating rod 8 includes a connecting part 81 located inside the table leg and a positioning part 82 located outside the table leg. The connecting part 81 is cylindrical and the positioning part 82 is rectangular. A magnet 811 is fixed to the end of the connecting part 81 away from the positioning part 82, realizing a detachable connection between the two rotating rods 8, thereby enabling a detachable connection of one end of the table leg on the splicing plate 61.

[0059] The inner wall of the storage slot 62 is provided with a receiving groove 621 for the rotating rod 8 to slide, and the inner wall of the receiving groove 621 is provided with a mounting hole 622 for the rotating rod 8 to slide out of the receiving groove 621. A push-pull rod 821 is fixed to the end of the positioning part 82 away from the connecting part 81 and the push-pull rod 821 is perpendicular to the positioning part 82, so that the user can slide the rotating rod 8 in the receiving groove 621, which facilitates the assembly and disassembly of one end of the table leg on the splicing plate 61.

[0060] Reference Figure 4 and Figure 5 Disconnect the connection between the two splicing plates 61, push the splicing plate 61 so that the pivot 611 is opposite to the through groove 312, then rotate the splicing plate 61 so that the splicing plate 61 is perpendicular to the mattress 5; move the splicing plate 61 away from the mattress 5 until only one end of the pivot 611 is located in the connecting block 31, and then connect the two splicing plates 61 together.

[0061] Reference Figure 6 and Figure 8 The sliding rod 821 slides the connecting part 81 out of the table leg to disconnect one end of the table leg from the splicing plate 61; the table leg is rotated away from the splicing plate 61 to provide support for the end of the splicing plate 61 away from the connecting block 31; then the insert strip 612 of one splicing plate 61 is inserted into the insert slot 613 of another splicing plate 61 to connect the two splicing plates 61. Both the mattress 5 and the splicing plate 61 can be used as the tabletop of the height-adjustable table, thereby expanding the tabletop area of ​​the height-adjustable tabletop.

[0062] Reference Figure 4 and Figure 9The table legs include two detachably connected support columns 7. One support column 7 has a snap-fit ​​block 71 at one end, and the other support column 7 has a snap-fit ​​groove 72 at one end for the snap-fit ​​block 71 to snap into. The snap-fit ​​block 71 has a through hole 711 through which a positioning part 82 passes, and the snap-fit ​​groove 72 has a clearance hole 721 on its side wall for the positioning part 82 to pass through.

[0063] After the two rotating rods 8 are removed from the receiving groove 621, they can be inserted into the through hole 711 of the snap-fit ​​block 71 through the clearance hole 721. When the rotating rods 8 are inserted into the snap-fit ​​block 71, the connecting part 81 of the two rotating rods 8 is fixedly connected in the through hole 711 by the magnet 811. Part of the positioning part 82 is located in the through hole 711 and part is located in the clearance hole 721 to achieve a fixed connection between the two support columns 7. Since the positioning part is a rectangular block, it is not easy for the two support columns to rotate relative to each other. When only one end of the rotating shaft 611 of the splicing plate 61 is connected to the connecting block 31, the table leg can provide support for the end of the splicing plate 61 away from the connecting block 31.

[0064] Reference Figure 4 and Figure 9 Pull the pivot 611 out from the connecting blocks 31 at both ends, so that the splicing plate 61 is completely separated from the base plate 3. Reinstall the rotating rod 8 into the receiving groove 621 so that the two ends of the table legs continue to be connected to the splicing plate 61. Rotate the two support columns 7 away from the splicing plate 61 so that the two support columns 7 provide support for the two ends of the splicing plate 61 respectively. At this time, the splicing plate 61 can be used as a bed desk to meet the different needs of users.

[0065] The implementation principle of a multifunctional sofa bed according to an embodiment of this application is as follows: Adjust the height of the lifting column 21 so that the base plate 3 is higher than the sofa 1, and rotate the base plate 3 by 90°; adjust the height of the lifting column 21 again so that the mattress 5 and the sofa 1 are at the same height, and then thread the positioning bolt through the positioning hole 2111 on a support sleeve 211 and thread it into the threaded hole 2112 on the adjacent support sleeve 211; push the two splicing plates 61 in opposite directions to disconnect the two splicing plates 61, and then rotate the splicing plates 61 away from the mattress 5 until the splicing plates 61 are perpendicular to the mattress 5; the mattress 5 and the two sofas 1 form a sofa bed for the user to rest;

[0066] When the desktop area of ​​the height-adjustable table is insufficient, rotate the two splicing plates 61 to be perpendicular to the mattress 5, and move the splicing plates 61 away from the mattress 5 so that only one end of the pivot 611 of the splicing plate 61 is connected to the connecting block 31. Then, insert the rotating rod 8 into the snap-fit ​​block 71 and connect the two support columns 7. Rotate the two table legs away from the splicing plates 61 so that the table legs provide support for the end of the splicing plate 61 away from the connecting block 31, thereby expanding the desktop area of ​​the height-adjustable table.

[0067] Install the rotating rod 8 back into the receiving slot 621 so that the two ends of the table legs are rotatably connected to the splicing plate 61, that is, both support columns 7 are rotatably connected to the splicing plate 61; at this time, the two support columns 7 provide support for the two ends of the splicing plate 61 respectively, and the splicing plate 61 can be used as a bed desk.

[0068] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
