Description

Technical Field

[0001] This utility model belongs to the technical field of sofas, and in particular relates to a freely combinable pull-out sofa bed. Background Technology

[0002] A sofa is a piece of furniture for resting, mainly consisting of a seat frame, backrest, and armrests. Traditional sofas are only for sitting and resting. With the development of the furniture industry, sofa beds have been designed, combining the functions of a sofa and a bed, allowing people to sit or lie down. Existing sofa beds, such as the one disclosed in Chinese Patent Publication No. CN216020148U, are modular sofa beds. Specifically, in sofa mode, one end of a first sofa bed is connected to one end of a second sofa bed. The first and second sofa bed bodies are respectively equipped with a first backrest and a second backrest, allowing the user to sit on the sofa with their back against the backrest. In bed mode, the first and second sofa bed bodies are joined together to form a bed. The first and second backrests are removed from the sofa, allowing the user to lie on the bed. Support cushions and a mattress provide support for the body. However, the backrests need to be removed to change the sofa mode to bed mode, resulting in limited configuration options and inconvenient assembly and disassembly. Utility Model Content

[0003] The purpose of this invention is to solve at least one problem of the prior art by proposing a freely combinable pull-out sofa bed.

[0004] To achieve the above objectives, this utility model proposes a freely combinable pull-out sofa bed, comprising:

[0005] Backrest, used for supporting the lower back;

[0006] Armrests, which are connected to the backrest;

[0007] The first seat frame is connected to the backrest or armrest. A bed frame is installed inside the first seat frame by a pull-out sliding mechanism. When the bed frame is pulled to the outside of the first seat frame, the sofa bed changes from a sofa state to a bed state. When the bed frame is pushed back into the first seat frame, the sofa bed returns from a bed state to a sofa state.

[0008] At least one second seat frame is provided, which is detachably connected to the armrest and the first seat frame. When multiple second seat frames are provided, the multiple second seat frames are provided on one or both sides of the first seat frame.

[0009] As an optional implementation, the second frame has a storage cavity inside, and the top of the second frame is fitted with a folding cover for sealing the storage cavity via a folding support structure.

[0010] As an optional implementation, the first seat frame and the second seat frame, or the second seat frame and the armrest, are connected by a connector and a plug-in.

[0011] As an optional implementation, the bed frame includes a slide with rollers at the bottom and a foldable support at the top. When the bed frame is pulled to the outside of the first seat frame, the support on the slide unfolds upward through folding brackets until the upper surface of the support is flush with or slightly lower than the first seat frame, thus changing the sofa bed from a sofa state to a bed state. When the bed frame needs to be pushed into the first seat frame, the support on the slide folds down through folding brackets until the slide can be pushed into the first seat frame, thus changing the sofa bed from a bed state to a sofa state.

[0012] As an optional implementation, the bed frame includes a carriage with rollers on its side, a slide rail inside the first seat frame, the rollers moving linearly along the slide rail, and baffles on both sides of the slide rail.

[0013] As an optional implementation, the backrest or the first seat frame is provided with a limiting block with a limiting slot, and the rear end of the carriage is provided with a stop post. When the carriage is fully pushed into the first seat frame, the two ends of the stop post just fit into the limiting slot of the limiting block.

[0014] As an optional implementation, a seat cushion may be placed on the first or second seat frame.

[0015] As an optional implementation, the armrest and the second seat frame are fixedly connected by screws or pins.

[0016] As an optional implementation, the armrest or the second seat frame is provided with a limiting member to restrict the bed frame from being pulled out to its extreme position.

[0017] As an optional implementation, the first seat frame includes two parallel support tubes, with connectors at both ends of the support tubes, and the support tubes are connected by Teslin fabric. The handrail or the second seat frame is provided with a support plug adapted to the connector.

[0018] The beneficial effects of this utility model are as follows: By detachably connecting the second seat frame with the armrest and the first seat frame, and when multiple second seat frames are provided, they can be arranged on one or both sides of the first seat frame, allowing users to freely change and combine the position and form of the sofa bed according to their needs; the bed frame is installed inside the first seat frame in a pull-out sliding manner, which allows the sofa bed to be easily switched between bed form and sofa form. The hidden bed frame makes the sofa bed more beautiful and reduces the area occupied.

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] See Figures 1 to 6 This embodiment provides a freely combinable pull-out sofa bed, including:

[0032] Backrest 1, for supporting the lower back;

[0033] Armrest 2, which is fixedly or detachably connected to backrest 1;

[0034] The first seat frame 3 is connected to the backrest 1 or the armrest 2. The bed frame 5 is installed inside the first seat frame 3 by a pull-out sliding mechanism. When the bed frame 5 is pulled to the outside of the first seat frame 3, the sofa bed changes from a sofa state to a bed state. When the bed frame 5 is pushed into the first seat frame 3, the sofa bed returns from a bed state to a sofa state.

[0035] At least one second seat frame 4 is provided, and the second seat frame 4 is detachably connected to the armrest 2 or the first seat frame 1. When multiple second seat frames 4 are provided, the multiple second seat frames 4 can be set on one or both sides of the first seat frame 1 according to user needs, so that the sofa bed can have multiple combination forms.

[0036] In actual use, the number of second seat frames 4 can be set according to the user's requirements for the size of the sofa bed and seating. The number of second seat frames 4 includes, but is not limited to, 1, 2, 3 or 4. The backrest 1, armrest 2, first seat frame 3 and second seat frame 4 are all equipped with protective covers. The protective covers can be leather covers, imitation leather covers or cloth covers. In order to improve the comfort of the sofa bed, elastic pads can also be set on the backrest 1, first seat frame 3 and second seat frame 4. The backrest 1 can be set as an integrated structure or as a split splicing structure, that is, the backrest 1 is connected to each first seat frame 3 and second seat frame 4 respectively.

[0037] In this embodiment, refer to Figure 2 The second frame 4 has a storage cavity inside. The top of the second frame 4 is equipped with a folding cover 41 for sealing the storage cavity through a folding support structure. The storage cavity can store items such as cushions or backrests. The inner wall of the storage cavity is provided with support columns for supporting the folding cover 41. The folding support structure is an existing structure, so it will not be described in detail in this application.

[0038] In this embodiment, refer to Figures 1 to 7The first seat frame 3 and the second seat frame 4, or the second seat frame 4 and the armrest 2, are connected by a connector and a snap-fit ​​joint. Both the connector and the snap-fit ​​joint have fastening holes for screws or pins. The connector can be a snap-fit ​​with a limiting groove that is wider at the top and narrower at the bottom, and the snap-fit ​​joint can be a snap-fit ​​plate that is wider at the top and narrower at the bottom. The snap-fit ​​plate conforms to the limiting groove, making the sofa bed easy to assemble and disassemble. Alternatively, the first seat frame 3 and the second seat frame 4, or the second seat frame 4 and the armrest 2, can be connected by tenon joints or screws.

[0039] In this embodiment, refer to Figures 1 to 5 The bed frame 5 includes a slide 51 with casters at the bottom and a foldable support at the top. When the bed frame 5 is pulled outside the first seat frame 3, the support on the slide 51 unfolds upwards via folding brackets until its upper surface is flush with or slightly lower than the first seat frame 3, transforming the sofa bed from a sofa to a bed. When the bed frame 5 needs to be pushed inside the first seat frame 3, the support on the slide 51 folds downwards via folding brackets until the slide can be pushed into the first seat frame 3, transforming the sofa bed from a bed to a sofa. This design ensures smooth operation of the slide 51 and convenient folding of the support. A pull ring can be provided on the support for easy lifting. For improved aesthetics, a sofa cover can also be provided at the front end of the first seat frame to conceal the bed frame.

[0040] In this embodiment, the bed frame 5 includes a slide, with rollers on the side of the slide and a slide rail inside the first seat frame 3. The rollers move linearly along the slide rail, and baffles are provided on both sides of the slide rail. The slide can be linearly moved and pulled out, and the baffles allow the slide to move within a certain range.

[0041] Further, see Figure 5 The backrest 1 or the first seat frame 3 is provided with a limiting block with a limiting slot, and the rear end of the carriage is provided with a stop post. When the carriage is fully pushed into the first seat frame, the two ends of the stop post just fit into the limiting slot of the limiting block.

[0042] In this embodiment, a seat cushion is placed on the first seat frame 3 or the second seat frame 4, or a backrest cushion can be placed on the first seat frame 3 or the second seat frame 4 to improve the user's sitting comfort.

[0043] In this embodiment, the armrest 2 and the second seat frame 4 are fixedly connected by screws or pins, which facilitates the assembly and disassembly of the armrest 2 and the second seat frame 4.

[0044] In this embodiment, refer to Figure 5 The armrest 2 or the second seat frame 4 is provided with a limiting component to limit the outward pulling limit position of the bed frame 5. The limiting component includes, but is not limited to, a screw, a limiting block, or a limiting post.

[0045] In this embodiment, refer to Figure 5 and Figure 6 The first seat frame 3 includes two parallel support tubes, with connectors at both ends of the support tubes. The support tubes are connected by Teslin fabric. The armrest 2 or the second seat frame 4 is equipped with a support plug adapted to the connector. In actual use, to improve the support strength, multiple reinforcing rods can be connected between the support tubes. Elastic pads can be placed on the reinforcing rods to improve the comfort of sitting.

[0046] The working process of this utility model:

[0047] In operation, this freely combinable pull-out sofa bed transforms into bed mode by pulling the bed frame 5 outwards, allowing it to move to the outside of the first seat frame 3 under the rolling action of the rollers on the slide 51. Lifting the support seat upwards causes the folding brackets to open, making the support seat and the first seat frame roughly flush, thus converting the sofa bed into bed mode. To revert to sofa mode, pressing down on the support seat folds the folding brackets downwards, pushing the bed frame back into the first seat frame. When combining with other sofas, the second seat frame can be placed on one side or both sides of the first seat frame, creating a pull-out bed with a single chaise lounge or a pull-out bed with two chaise lounges, better meeting user needs.

[0048] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
