Description

Technical Field

[0001] The utility model relates to the technical field of furniture, and more specifically, to a multifunctional sofa. Background Art

[0002] As people's living standards continue to improve, people's requirements for furniture are getting higher and higher. Ordinary sofas with single functions will gradually be abandoned by people. Today's sofas can automatically adjust their shapes according to different people's sitting postures and body shapes.

[0003] Existing sofas with adjustable shapes mostly use a folding structure to expand the main structure of the sofa. However, the folding structure is usually supported by a frame structure, and its support strength is limited by the rod frame structure. If a filled solid structure is used for support, the structural mobility will be limited.

[0004] In view of this, the present invention provides an effective solution to the problem that existing multifunctional sofas are difficult to balance stability and functionality. Utility Model Content

[0005] The technical problem to be solved by the present invention is that the expansion structure of the existing multifunctional sofa usually adopts a frame support, which is easy to collapse in some parts and has limited stability and mobility. In view of the problems existing in the prior art, a multifunctional sofa is provided.

[0006] The purpose and effect of the utility model are achieved by the following specific technical means: comprising a bottom frame seat and a back plate, the back plate is fixed to one end of the bottom frame seat, a pull-out cabinet and a side seat are horizontally connected horizontally and vertically on the bottom frame seat, and the pull-out cabinet is slidably connected to the bottom frame seat, a plurality of casters are fixed at the bottom corners of the pull-out cabinet, and a folding plate is folded in the pull-out cabinet;

[0007] The rubbing plate is an independent plate with the same cushion material as the sofa. A base plate frame and a bottom plate frame are arranged in parallel between the rubbing plate and the pull-out cabinet, and a combined support rod is hingedly arranged on both sides between the base plate frame and the bottom plate frame.

[0008] A reinforcing piece is inserted between the combined support rod near the inner end of the expansion plate and the base plate frame. A sliding shaft tube-type connecting shaft is axially fixed between the two ends of the reinforcing piece and the base plate frame and the combined support rod, and an angle wheel is hingedly provided between the connecting shaft and the combined support rod.

[0009] Furthermore: side frames are fixedly arranged on both sides between the bottom frame seat and the back plate, and the bottom frame seat, side frames and pull-out cabinet are all hollow frame structures with peach core boards attached to the outside.

[0010] A further preferred solution is that the outward extension length of the extension plate is at least 4 mm less than the maximum sliding distance of the pull-out cabinet.

[0011] A further preferred solution is that the reinforcing piece and the sliding shaft pipe end of the connecting shaft are filled with a compression spring with half the pipe distance.

[0012] A further preferred solution is that a corner bar frame is hingedly provided between the reinforcing piece and the base plate frame, and the maximum folding range of the corner bar frame is less than 45°.

[0013] A further preferred solution is that the maximum foldable frame structure of the base plate frame, the bottom plate frame and the combined support rod member is a trapezoidal structure.

[0014] A further preferred solution is that the side seat is a split upper and lower plate frame structure, a storage frame is hollowed out in the side seat, and a spring connecting rod is hingedly provided between the side seat upper plate and the side seat lower frame.

[0015] Beneficial effects of the utility model:

DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, Figure 1-Figure 5 The present invention is further described in detail in the following embodiments. The following embodiments are merely examples of implementing the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the scope of the present invention are within the scope of patent protection of the present invention.

[0025] A multifunctional sofa comprises a bottom frame 1 and a backboard 5, wherein the backboard 5 is fixed to one end of the bottom frame 1, a pull-out cabinet 3 and a side seat 4 are arranged on the bottom frame 1 in a horizontal and vertical manner, and the pull-out cabinet 3 is slidably connected to the bottom frame 1, a plurality of casters 7 are fixed at the bottom corners of the pull-out cabinet 3, and a folding plate 6 is provided in the pull-out cabinet 3;

[0026] The extension board 6 is an independent plate with the same cushion material as the sofa. A base frame 9 and a bottom frame 10 are arranged parallel to the extension board 6 and the pull-out cabinet 3, and a combined support rod 8 is hingedly arranged on both sides between the base frame 9 and the bottom frame 10.

[0027] A reinforcing piece 11 is inserted between the combined support rod 8 and the base plate frame 9 near the inner end of the extension plate 6. A sliding shaft tube-type connecting shaft 13 is axially fixed between the two ends of the reinforcing piece 11 and the base plate frame 9 and the combined support rod 8, and a corner wheel 14 is hingedly provided between the connecting shaft 13 and the combined support rod 8.

[0028] The main structure of the multifunctional sofa is mainly composed of a bottom frame 1 and a backboard 5, which are overlapped to form a separate pull-out cabinet 3 and a side seat 4. The pull-out cabinet 3 and the bottom frame 1 are an expansion structure with sliding ends. The pull-out cabinet 3 can be pulled out from the bottom frame 1 to remove the expansion board 6 in the pull-out cabinet 3 from the folded end. Through the folding deformation of the base frame 9, the bottom frame 10 and the combined support rod 8 in the expansion board 6, the expansion board 6 is made to overlap with the bottom frame 1 and the edges of the two ends of the pull-out cabinet 3 after being fully stretched, completing the expansion of the sitting space of the pull-out cabinet 3 structure;

[0029] Compared with the expansion structure of the existing multifunctional sofa, in order to ensure the structural strength and mobility of the sofa, this sofa adopts a combined side support form, and cooperates with the reinforcement parts 11 interspersed therein to support the upright position of the expansion board. The support structure can match the support angle and support stability of the combined support rod 8 with the sliding displacement of the connecting shaft 13 sliding tube and the articulation change of the corner wheel 14. While adopting the frame structure to ensure mobility, it effectively improves the stability of the expansion structure, so that the expansion structure of this multifunctional sofa has the same support strength as the main structure to meet the needs of different usage scenarios and functional expansion.

[0030] Furthermore, side frames 2 are fixedly provided on both sides between the bottom frame seat 1 and the back panel 5, and the bottom frame seat 1, the side frames 2, and the pull-out cabinet 3 are all hollow frame structures with peach core boards attached to the outside. The main structure is mainly formed by the peach core board encapsulated frame structure, which ensures the lightness of the non-supporting structural surface while having the strength of the structural outer lining, thereby avoiding the influence of the redundant structure on the activity of the sofa.

[0031] Furthermore, the outward extension length of the extension plate 6 is at least 4 mm less than the maximum sliding distance of the pull-out cabinet 3. The relatively controlled outward extension distance of the extension plate 6 ensures that when the pull-out cabinet 3 is stretched, the maximum sliding space of the extension plate 6 can be folded, so that the position of the extension plate 6 can be fixed and folded for storage later.

[0032] Furthermore, the ends of the sliding shaft tubes of the reinforcing member 11 and the connecting shaft 13 are filled with compression springs with a half-tube pitch. Within the sliding shaft tube space between the reinforcing member 11 and the connecting shaft 13, the front end of the connecting shaft 13 expands and contracts mainly within the space of the reinforcing tube body, while the rear end expands and contracts simultaneously compresses the compression springs, providing a buffer space for the axial support of the reinforcing member 11 and the connecting shaft 13, thereby preventing large impact forces from affecting the stability of the reinforcing member 11 and the combined strut member 8.

[0033] Furthermore, a corner bar frame 12 is hingedly provided between the reinforcement member 11 and the base frame 9. The maximum folding range of the corner bar frame 12 is less than 45 degrees. Based on the reinforcement member 11, the corner bar frame 12 can utilize the hinged structure of the middle portion to shrink and fold, and cooperate with the combined support member 8 to fold and stretch the inner corner. At the same time, the maximum folding range of the corner bar frame 12 is controlled to limit the hinge position of the reinforcement member 11 and the combined support member 8. At the same time, when restricted to the limit position, the corner bar frame 12 also has a certain lateral support strength, further improving the stability of the support structure.

[0034] Furthermore, the maximum foldable frame structure of the base plate frame 9 , the bottom plate frame 10 and the combined support member 8 is a trapezoidal structure, which effectively reinforces the upright support strength of the combined support member 8 and the reinforcing member 11 .

[0035] Furthermore, the side seat 4 is a split upper and lower plate frame structure, a storage frame 16 is hollowed out in the side seat 4, and a spring connecting rod 15 is hingedly provided between the upper plate of the side seat 4 and the lower frame of the side seat 4. The sofa further expands the storage function of the sofa through the opening and closing structure of the side seat 4, and the storage frame 16 can be used to store items by flipping open the upper plate of the side seat 4.
