Description

Technical Field

[0001] This utility model relates to the field of home furnishing technology, and in particular to a support mechanism and a compression sofa. Background Technology

[0002] With living spaces becoming increasingly compact, compact sofas are gradually becoming the preferred furniture for small apartments and temporary living scenarios due to their advantages of small footprint and ease of movement. While consumers are pursuing their adaptability to different spaces, their demands for stability and user experience are also constantly increasing.

[0003] However, existing compact sofas on the market generally suffer from core technological shortcomings: their armrests and backrests have poor structural design and lack a stable support mechanism, making them prone to tilting and sagging during daily use. This not only affects seating comfort but also poses safety hazards. Furthermore, most of these compact sofas lack dedicated support legs, relying solely on the main structure's contact with the ground for support. This results in a lack of the neatness and three-dimensionality of fixed sofas, failing to achieve their aesthetic appeal. The absence of support legs further exacerbates the instability problem, making compact sofas significantly inferior to fixed sofas in terms of user experience. This makes it difficult to meet consumers' dual demands for practicality and aesthetics in furniture, becoming a key pain point hindering the market promotion of compact sofas. Utility Model Content

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] It should be noted that the "backrest" and "armrest" mentioned in the embodiments of this application can be the backrest 3 and armrest 4 of upholstered furniture such as soft beds, compressed sofas, soft sofas, and chairs, and should specifically correspond to which backrest 3 and armrest 4 depending on the specific application of the support mechanism 1. Specifically, in the embodiments below, the backrest 3 and armrest 4 are the backrest 3 and armrest 4 of a compressed sofa.

[0024] Reference Figures 1 to 6e As shown, this invention illustrates an embodiment of the support mechanism 1 and the compression sofa. The support mechanism 1 includes a base 11 and a support plate 12, which is rotatably connected to the base 11. The support plate 12 includes a first support plate 121 and a second support plate 122, which are located on adjacent sides of the base 11. During installation, the first support plate 121 and the second support plate 122 are rotated to position them vertically above the base 11. The first support plate 121 is embedded in the backrest 3, and the second support plate 122 is embedded in the armrest 4.

[0025] Specifically, the support mechanism 1 is used to support the backrest 3 and armrest 4, thereby preventing the backrest 3 and armrest 4 from becoming unstable and tilting or sagging. The support mechanism 1 includes a base 11 and a support plate 12. The support plate 12 is used to support the backrest 3 and armrest 4, and the base 11 is used to support the support plate 12 and the seat cushion 2. The support plate 12 includes a first support plate 121 and a second support plate 122. The first support plate 121 is used to support the backrest 3, and the second support plate 122 is used to support the armrest 4. Both the first support plate 121 and the second support plate 122 are rotatably connected to the base 11, so that the first support plate 121 and the second support plate 122 can be in a horizontal or vertical state located on the upper end of the base 11.

[0026] When the support mechanism 1 is being transported, the first support plate 121 and the second support plate 122 are rotated to be positioned horizontally on the upper end of the base 11, and the first support plate 121, the second support plate 122, the base 11, the backrest 3, the seat cushion 2, and the armrest 4 are compressed and packed into a box to increase the packing volume during transportation and reduce transportation costs.

[0027] When installing the support mechanism 1, backrest 3, and armrest 4, the first support plate 121 and the second support plate 122 need to be rotated first so that the first support plate 121 and the second support plate 122 are respectively located vertically on adjacent sides of the base 11. The vertical state means that the first support plate 121 and the second support plate 122 can be installed vertically or inclinedly above the base 11. The first support plate 121 and the second support plate 122 need to be vertically located above the base 11, and the installation angle of the two must meet the requirement that the first support plate 121 and the second support plate 122 can stably support the backrest 3 or the armrest 4. The specific installation angle is not limited here, and can be freely designed according to the actual size and shape of the backrest 3 and the armrest 4. In this embodiment, the first support plate 121 and the second support plate 122 are located on the base 11 with a support angle of 90°.

[0028] After the first support plate 121 and the second support plate 122 are vertically positioned on the base 11, the seat cushion 2 is then installed on the top of the base 11. The base 11 provides support for the seat cushion 2, preventing the seat cushion 2 from directly contacting the ground, thus avoiding dampness, mold, or inconvenience for cleaning. The seat cushion 2 has a groove to avoid the first support plate 121 and the second support plate 122. To ensure that the first support plate 121 and the second support plate 122 support the backrest 3 and the armrest 4 respectively, the height of the first support plate 121 and the second support plate 122 needs to be greater than the height of the seat cushion 2.

[0029] Finally, the backrest 3 and armrest 4 are installed on the top of the seat cushion 2. Both the backrest 3 and the armrest 4 are provided with grooves, so that the first support plate 121 and the second support plate 122 can be embedded into the backrest 3 and the armrest 4 respectively. This allows the first support plate 121 and the second support plate 122 to provide stable support for the backrest 3 and the armrest 4 respectively, preventing the backrest 3 and the armrest 4 from tilting or sagging. At the same time, embedding the first support plate 121 and the second support plate 122 into the backrest 3 and the armrest 4 can hide the support mechanism 1, thereby improving the aesthetics of the furniture.

[0030] Therefore, when using or transporting the first support plate 121 and the second support plate 122, users only need to rotate the first support plate 121 and the second support plate 122 to make it easy and quick for users to assemble and pack them.

[0031] In this embodiment, by setting up the support mechanism 1, the first support plate 121 and the second support plate 122 are rotatably mounted on adjacent sides of the base 11. During assembly, the first support plate 121 and the second support plate 122 are rotated so that they are respectively positioned vertically on adjacent sides of the base 11. The first support plate 121 stably supports the backrest 3, and the second support plate 122 stably supports the armrests 4, so that the backrest 3 and the armrests 4 have fixed support components inside, so that they can be stably supported and prevent the backrest 3 and the armrests 4 from tilting or sagging. At the same time, the support mechanism 1 enhances the three-dimensionality of the sofa, thereby improving its aesthetics. Furthermore, during transportation, the first support plate 121 and the second support plate 122 are rotated so that they are respectively positioned horizontally on the upper end of the base 11, and the compressed backrest 3, seat cushion 2, and armrests 4 are packed together in a box, increasing the packing rate and reducing transportation costs.

[0032] In one embodiment, reference is made to Figures 1 to 3b As shown, both the first support plate 121 and the second support plate 122 are provided with a plurality of spaced-apart first notches 123, which extend along the height direction of the first support plate 121 and the second support plate 122. Specifically, both the first support plate 121 and the second support plate 122 are plate-shaped structures, and can be wood or metal plates; both the first support plate 121 and the second support plate 122 are provided with a plurality of first notches 123, which are spaced-apart. The first notches 123 on the first support plate 121 extend along the height direction of the first support plate 121, and the first notches 123 on the second support plate 122 extend along the height direction of the second support plate 122. The height direction refers to the height direction of the first support plate 121. The first notch 123 extends through the upper and lower sides of the first support plate 121 or the second support plate 122 when they are installed vertically on the base 11. The upper and lower sides refer to the upper and lower sides when the first support plate 121 and the second support plate 122 are installed horizontally on the base 11. The first notch 123 is used to reduce the material of the first support plate 121 and the second support plate 122, that is, the first support plate 121 and the second support plate 122 adopt a hollow design, which can reduce the production cost of the support mechanism 1.

[0033] In a specific embodiment, refer to Figures 1 to 3b As shown, the corners of the first support plate 121 and the second support plate 122 are both arc-shaped, thus eliminating the sharp structures of the first support plate 121 and the second support plate 122. This prevents damage to the backrest 3 and the armrest 4 when the first support plate 121 and the second support plate 122 are embedded into them, thereby improving assembly efficiency.

[0034] In one embodiment, reference is made to Figures 1 to 3b As shown, the base 11 includes a base plate 111 and a support foot 112. The upper end of the base plate 111 is rotatably connected to the support plate 12, and the lower end of the base plate 111 is detachably connected to the support foot 112. Specifically, the base plate 111 supports the seat cushion 2 and the support plate 12. The base plate 111 is a horizontal plate structure and can be a metal plate or a wooden board. The support legs 112 support the base plate 111 to keep the sofa off the ground, ensuring its cleanliness and preventing mold and dampness. Simultaneously, the support legs 112 make the sofa consistent with conventional sofas, providing the same appearance and functionality as a fixed sofa, improving the aesthetics and practicality of the furniture with the support mechanism 1. Furthermore, since the base plate 111 and the support legs 112 are detachably connected, they can be disassembled and packed during packaging, allowing for a much larger packing size than conventional fixed sofas, reducing transportation costs and preventing damage to the base plate 111 or the support legs 112 during transport.

[0035] Furthermore, the support foot 112 and the base plate 111 are connected by threads, which simplifies the connection and improves the user's disassembly and assembly efficiency.

[0036] In a specific embodiment, refer to Figures 1 to 3b As shown, the base plate 111 has a plurality of spaced second notches 113, which extend along the length of the base plate 111. Specifically, the base plate 111 has a plurality of second notches 113, which are spaced apart and extend along the length of the base plate 111. The length direction refers to the same direction as the extension direction of the first notch 123 when the first support plate 121 and the second support plate 122 are installed horizontally on the base 11. The second notches 113 penetrate the upper and lower sides of the base plate 111. The second notches 113 are used to reduce the material content of the base plate 111, that is, the base plate 111 adopts a hollow design, which can reduce the production cost of the support mechanism 1.

[0037] In a specific embodiment, refer to Figures 1 to 3b As shown, the support plate 12 includes a first support plate 121 and a second support plate 122, which are located at opposite ends of the diagonal of the base 11. Specifically, only one first support plate 121 and one second support plate 122 are installed on the base 11. The first support plate 121 is rotatably disposed on one side of the base 11, and the second support plate 122 is rotatably disposed on the adjacent other side of the base 11. This allows the first support plate 121 to support the backrest 3 and the second support plate 122 to support the armrest 4. The first support plate 121 and the second support plate 122 are located at opposite ends of the diagonal of the base 11, thereby increasing the distance between them. This improves the stability of the support provided by the first support plate 121 and the second support plate 122 to the backrest 3 and the armrest 4, respectively, and further prevents the backrest 3 and the armrest 4 from tilting or sagging.

[0038] In one embodiment, the support plate 12 includes a plurality of first support plates 121 and a plurality of second support plates 122 (not shown in the figure). The plurality of first support plates 121 are spaced apart along one side of the base 11, and the plurality of second support plates 122 are spaced apart along the other side of the base 11. That is, a plurality of first support plates 121 and a plurality of second support plates 122 are spaced apart on adjacent sides of the base 11. The first support plates 121 and the plurality of second support plates 122 provide stable support for the backrest 3 and the armrest 4, thereby further improving the support stability of the support mechanism 1 for the backrest 3 or the armrest 4.

[0039] Furthermore, the first support plate 121 or the second support plate 122 are integrally formed to improve the structural stability and production efficiency of the first support plate 121 and the second support plate 122, while also increasing the service life of the first support plate 121 and the second support plate 122.

[0040] In a specific embodiment, refer to Figures 1 to 5 As shown, the first support plate 121 and the second support plate 122 are rotatably connected to the base 11 via a hinge 13. Since the hinge 13 has a simple structure, low production cost, and high stability, the first support plate 121 and the second support plate 122 are highly stable when rotating on the base 11. Furthermore, the connection between the first support plate 121 and the second support plate 122 and the base 11 is simple and has low production cost.

[0041] Furthermore, both sides of the first support plate 121 and the second support plate 122 are rotatably connected to the base 11 via hinges 13, that is, both sides of the first support plate 121 are fixed to the hinges 13, and both sides of the second support plate 122 are fixed to the hinges 13, so as to make the connection between the first support plate 121 and the second support plate 122 and the base 11 more stable, and at the same time improve the stability of rotation.

[0042] As stated above, with reference to Figures 1 to 3b As shown, in this embodiment, both the first support plate 121 and the second support plate 122 are provided with positioning openings 124, which are formed by the first support plate 121 or the second support plate 122 being recessed inward along one side of its height direction. Specifically, the positioning port 124 is used to position the first support plate 121 and the second support plate 122 and the hinge 13 in a fixed position. The positioning port 124 located on the first support plate 121 is located on one side of the first support plate 121 along its height direction, and the positioning port 124 located on the second support plate 122 is located on one side of the second support plate 122 along its height direction. That is, when the first support plate 121 and the second support plate 122 are installed vertically on the base 11, the positioning port 124 is a certain distance away from the base 11. This allows the hinge 13 to be fixedly installed downwards from the positioning port 124 when installing the hinge 13 and the first support plate 121, and the hinge 13 and the second support plate 122, thereby improving installation efficiency and accuracy.

[0043] In a specific embodiment, refer to Figures 3a to 3bAs shown, the hinge 13 includes a first connecting rod 131, a second connecting rod 132, and a third connecting rod 133. The first connecting rod 131 is fixedly connected to the base 11. One end of the second connecting rod 132 is rotatably connected to the first connecting rod 131 and is fixedly connected to one side of the support plate 12. One end of the third connecting rod 133 is rotatably connected to the first connecting rod 131, and the other end of the third connecting rod 133 is slidably connected to the second connecting rod 132. Specifically, the first connecting rod 131, the second connecting rod 132, and the third connecting rod 133 are interconnected. The bottom end of the first connecting rod 131 is fixedly connected to the base 11. One side of the second connecting rod 132 is fixedly connected to the first support plate 121 or the second support plate 122. The bottom end of the second connecting rod 132 is rotatably connected to one end of the first connecting rod 131, thereby allowing the second connecting rod 132 to drive the first support plate 121 or the second support plate 122 to rotate on the base 11. One end of the third connecting rod 133 is rotatably connected to the first connecting rod 131, and the other end of the third connecting rod 133 is slidably connected to the second connecting rod 132.

[0044] Reference Figure 3a As shown, when the support mechanism 1 is installed with the sofa, the user rotates the first support plate 121 or the second support plate 122 in the vertical direction. The first support plate 121 or the second support plate 122 drives the second connecting rod 132 to rotate, so that the third connecting rod 133 slides on the second connecting rod 132, thereby causing the third connecting rod 133 to rotate on the first connecting rod 131 until the third connecting rod 133 slides to the designated position. At this time, the third connecting rod 133, the first connecting rod 131, and the second connecting rod 132... A triangular structure is formed, with the third connecting rod 133 pressing against the second connecting rod 132 to prevent the second connecting rod 132 from falling off. This allows the second connecting rod 132 and the first connecting rod 131 to form a specified angle, which is less than or equal to 90°. It is only necessary to ensure that this angle can stably support the backrest 3 or the armrest 4, so that the first support plate 121 or the second support plate 122 is vertically installed on the base 11 at the specified angle, thereby allowing the first support plate 121 or the second support plate 122 to stably support the backrest 3 or the armrest 4.

[0045] Reference Figure 3bAs shown, when packing is required, the user rotates the first support plate 121 or the second support plate 122 toward the base 11. The first support plate 121 or the second support plate 122 drives the second connecting rod 132 to rotate, so that the third connecting rod 133 slides on the second connecting rod 132. Finally, the third connecting rod 133, the second connecting rod 132 and the first connecting rod 131 are all horizontally positioned above the base 11. At this time, the first support plate 121 or the second support plate 122 are all horizontally positioned above the base 11, which facilitates the packing of the support mechanism 1, increases the packing capacity, and reduces transportation costs.

[0046] The hinge 13 in this embodiment has a simple structure and high stability, so that the rotational stability of the first support plate 121 and the second support plate 122 is high.

[0047] More specifically, the second connecting rod 132 is provided with a slot (not shown in the figure), which engages with the third connecting rod 133. By providing a slot in the second connecting rod 132, the slot is used to limit the sliding distance of the third connecting rod 133. By engaging the third connecting rod 133 with the slot, the sliding of the third connecting rod 133 is restricted, thereby allowing the third connecting rod 133 to support the second connecting rod 132 at a specified angle. This results in the first connecting rod 131, the second connecting rod 132, and the third connecting rod 133 forming a stable triangular structure. Consequently, the second connecting rod 132 and the first connecting rod 131 support the first support plate 121 and the second support plate 122 at a specified angle, improving the stability of the hinge 13 structure.

[0048] As stated above, with reference to Figures 3a to 3bAs shown, in this embodiment, the inner side of the second connecting rod 132 is provided with a limiting part 134, which extends toward the third connecting rod 133 and is used to limit the third connecting rod 133. Specifically, a limiting part 134 is provided on the inner side of the second connecting rod 132, where the inner side refers to the side of the second connecting rod 132 facing the first connecting rod 131. The limiting part 134 and the support plate 12 are respectively located on both sides of the second connecting rod 132, and the limiting part 134 extends towards the third connecting rod 133. The limiting part 134 is located above the third connecting rod 133, that is, above the sliding distance of the third connecting rod 133. When the third connecting rod 133 slides towards the limiting part 134, the limiting part 134 abuts against the third connecting rod 133 to prevent the third connecting rod 133 from continuing to slide, thereby improving the stability of the support plate 12 and the base 11 when rotating.

[0049] Reference Figure 1 , Figures 6a to 6e As shown, this embodiment also provides a compression sofa, which includes a seat cushion 2, a backrest 3, armrests 4, and a support mechanism 1. The backrest 3 and armrests 4 are located at the top of the seat cushion 2. The support mechanism 1 can be any type of support mechanism 1 provided by this utility model. Since the specific structure and working principle of the support mechanism 1 have been described in detail in the previous description, they will not be repeated here for the sake of brevity. The base 11 is located at the bottom of the seat cushion 2. The first support plate 121 is embedded in the seat cushion 2 and the backrest 3, and the second support plate 122 is embedded in the seat cushion 2 and the armrests 4.

[0050] The compressed sofa in this embodiment utilizes the support mechanism 1 provided by this invention. The support mechanism 1 supports the seat cushion 2, backrest 3, and armrests 4, preventing the backrest 3 and armrests 4 from tilting or sagging, thus increasing the stability of the compressed sofa and improving the user experience. Simultaneously, the support mechanism 1 enhances the regularity and three-dimensionality of the compressed sofa, improving its aesthetics. Furthermore, it enables the compressed sofa to function as a fixed sofa, increasing its practicality. Moreover, the packing capacity of the compressed sofa is significantly greater than that of a conventional fixed sofa, thereby enhancing its market competitiveness.

[0051] In one embodiment, Figures 6a to 6eThe seat cushion 2 is provided with a first mounting groove 21 that runs through its upper and lower ends, the backrest 3 is provided with a second mounting groove 31 that opens upward from its bottom end, and the armrest 4 is provided with a third mounting groove 41 that opens upward from its bottom end. One end of the first support plate 121 passes through the first mounting groove 21 and is embedded in the second mounting groove 31, and one end of the second support plate 122 passes through the first mounting groove 21 and is embedded in the third mounting groove 41. Specifically, the seat cushion 2 has a first mounting groove 21 at the position corresponding to the support frame. Since the armrest 4 and the backrest 3 are both located above the seat cushion 2, the first mounting groove 21 needs to pass through the upper and lower ends of the seat cushion 2 so that the first support plate 121 or the second support plate 122 can pass through the first mounting groove 21 and be embedded in the backrest 3 or the armrest 4. The second mounting groove 31 and the third mounting groove 41 are respectively used to accommodate the first support plate 121 and the second support plate 122, so that the first support plate 121 and the second support plate 122 can be hidden in the seat cushion 2, the backrest 3 and the armrest 4, thereby improving the aesthetics of the compressed sofa and also improving the support stability of the first support plate 121 and the second support plate 122 for the backrest 3 and the armrest 4.

[0052] More specifically, the compressed sofa also includes a filling element for filling the second mounting groove 31 and the third mounting groove 41, and the filling element is located on the outside of the support plate 12, thereby preventing the support plate 12 from being exposed on the outside of the compressed sofa and further improving the aesthetics of the compressed sofa.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
