Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a composite spring compression sofa. Background Technology

[0002] A compression sofa is a type of sofa that can be compressed as a whole, which can significantly reduce its volume during transportation, thereby reducing transportation costs. After arriving at its destination, it can be unpacked and reshaped without complicated installation.

[0003] Currently, there is a type of compression sofa on the market that uses individually pocketed springs for support. Each spring inside the sofa is independently housed in a fabric pocket, so they do not affect each other. This allows for a more precise fit to the human body's curves, providing personalized support while reducing friction and noise between the springs. To achieve overall compression of the sofa, the armrests also use individually pocketed springs for support. However, in this type of structure, because the sides of the individually pocketed springs do not have a retractable function, when users lean against the armrests, the sides of the armrests exert a hard pressure on the user, causing discomfort and affecting the user experience. Therefore, to avoid this situation, a composite spring compression sofa is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a composite spring compression sofa in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite spring compression sofa, including a sofa seat, a concave backrest and sponge armrests fixed to the top of the sofa seat, and two sponge armrests symmetrically distributed at the front end of the concave backrest;

[0006] The sofa seat and concave backrest are filled with pocket springs, which are arranged in a matrix inside the sofa seat and concave backrest and are connected to each other by adhesive.

[0007] The inner side of the sofa seat is also provided with a limiting frame. The independent pocket springs inside the sofa seat are distributed inside the limiting frame, and the independent pocket springs adjacent to the limiting frame are fastened to the limiting frame by a ring metal buckle. The part of the independent pocket spring on the inner side of the concave backrest near the rear end is fastened to the outer fabric of the concave backrest by a ring metal buckle.

[0008] As a further improvement of this utility model: the location of the independent spring in the bag can be replaced by a combined spring group, which consists of multiple sets of horizontal spring groups and vertical spring groups, and the multiple sets of horizontal spring groups and vertical spring groups are distributed perpendicularly and alternately to each other.

[0009] The transverse spring assembly consists of a large independent bag spring, a limiting independent bag spring, and a first connecting strip. Multiple large independent bag springs are arranged in the horizontal direction. Two limiting independent bag springs are located between two adjacent large independent bag springs and are arranged symmetrically in the upper and lower parts. The limiting independent bag springs are sewn to the large independent bag springs through the first connecting strip.

[0010] The longitudinal spring group consists of snap-fit ​​independent bag springs, small bag independent springs, and a second connecting strip. The snap-fit ​​independent bag springs are distributed between two adjacent transverse spring groups and there are two of them. The snap-fit ​​independent bag springs are snapped between the two limiting bag independent springs. The snap-fit ​​independent bag springs are sewn together with a small bag independent spring and the two small bag independent springs through the second connecting strip.

[0011] The snap-fitting mechanism between the independent bag springs and the limiting independent bag springs is used to achieve vertical mutual limiting of the horizontal spring group and the vertical spring group, thereby replacing the adhesive connection method of the independent bag springs.

[0012] As a further embodiment of this utility model: the connection position of the first connecting strip to the independent spring of the large bag is far away from the upper and lower ends of the independent spring of the large bag, and the connection position of the first connecting strip to the upper and lower limiting independent springs of the bag is close to the bottom and top ends of the two limiting independent springs of the bag, respectively.

[0013] As a further embodiment of this utility model: the overall distribution trajectory of the snap-fit ​​independent spring for the small bag and the independent spring for the small bag is in the shape of an inverted "S" shape. The height of the second connecting strip is less than the height of the snap-fit ​​independent spring for the small bag, and the connection position of the second connecting strip with the independent spring for the small bag and the independent spring for the snap-fit ​​independent spring is located in the middle of the independent spring for the small bag and the independent spring for the snap-fit ​​independent spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating integrally molded sponge armrests, the sofa can still be compressed as a whole, ensuring convenient transportation. Simultaneously, the sponge armrests possess excellent vertical and lateral elasticity, providing a more comfortable feel when in contact with the user, further enhancing the sofa's usability. Furthermore, a modular spring system replaces the traditional individual pocket springs. The snap-fit ​​connection between the individual pocket springs and the limiting individual pocket springs achieves vertical mutual restraint between the horizontal and vertical spring groups, replacing the adhesive connection method of traditional individual pocket springs and better aligning with people's health concepts.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see Figures 1-2 In this embodiment of the utility model, the composite spring compression sofa includes a sofa seat 1, a concave backrest 2 and a sponge armrest 3 fixed on the top of the sofa seat 1, and two sponge armrests 3 are provided, which are symmetrically distributed at the front end of the concave backrest 2.

[0027] The sofa seat 1 and concave backrest 2 are filled with pocket springs 5. The pocket springs 5 ​​are distributed in a matrix inside the sofa seat 1 and concave backrest 2 and are connected to each other by glue.

[0028] The inner side of the sofa seat 1 is also provided with a limiting frame 4. The independent pocket springs 5 ​​inside the sofa seat 1 are distributed inside the limiting frame 4. The independent pocket springs 5 ​​adjacent to the limiting frame 4 are fastened to the limiting frame 4 by a ring metal buckle 6. The part of the independent pocket spring 5 on the inner side of the concave backrest 2 near the rear end is fastened to the outer fabric of the concave backrest 2 by a ring metal buckle 6.

[0029] In this embodiment, it should be noted that: the sofa seat 1 and the concave backrest 2 are both composed of an outer fabric covering and independent pocket springs 5, and the two sets of vertically distributed independent pocket springs 5 ​​are filled with soft material (such as sponge material). The sofa seat 1, the concave backrest 2, and the sponge armrests 3 are also covered with an outer layer. These structures are existing technology for sofas, so they will not be described in detail here.

[0030] By incorporating sponge armrests 3, which are integrally molded from sponge material, the sofa can still be compressed as a whole, ensuring convenient transportation. At the same time, the sponge armrests 3 have good elasticity in both vertical and lateral directions, making the contact with the human body more comfortable and further improving the user experience of the sofa. Example 2

[0031] Please refer to this carefully. Figures 2-7 The location of the independent bag spring 5 can be replaced by a combined spring group 5a. The combined spring group 5a consists of multiple sets of horizontal spring groups and vertical spring groups, which are distributed perpendicularly to each other.

[0032] The transverse spring assembly consists of a large bag independent spring 501, a limiting bag independent spring 502, and a first connecting strip 503. Multiple large bag independent springs 501 are arranged along the horizontal transverse direction. Two limiting bag independent springs 502 are located between two adjacent large bag independent springs 501 and are arranged symmetrically in the upper and lower parts. The limiting bag independent springs 502 are sewn to the large bag independent springs 501 through the first connecting strip 503.

[0033] The longitudinal spring group consists of a snap-fit ​​independent bag spring 504, a small bag independent spring 505, and a second connecting strip 506. The snap-fit ​​independent bag spring 504 is distributed between two adjacent transverse spring groups and there are two of them. The snap-fit ​​independent bag spring 504 is snapped between two limiting bag independent springs 502. The snap-fit ​​independent bag spring 504 is sewn to a small bag independent spring 505 and the two small bag independent springs 505 through the second connecting strip 506.

[0034] The snap-fitting of the independent bag spring 504 and the limiting independent bag spring 502 is used to achieve vertical mutual limiting of the horizontal spring group and the vertical spring group, thereby replacing the adhesive connection method of the independent bag spring 5.

[0035] In this embodiment: a matrix structure composed of multiple sets of horizontal and vertical spring groups can provide sufficient elastic support for the use of the sofa. The snap-fit ​​independent pocket spring 504 and the limiting independent pocket spring 502 are used to realize the vertical mutual limiting of the horizontal and vertical spring groups, thereby replacing the traditional adhesive connection method of the independent pocket spring 5, which is more in line with people's health concept, and thus facilitates the promotion and sales of the sofa.

[0036] It should be noted that the large bag independent spring 501, the limiting bag independent spring 502, the snap-fit ​​bag independent spring 504, and the small bag independent spring 505 are all formed by wrapping the spring with fabric and then sewing it together, which is the same as the existing bag independent spring 5 in terms of structural principle.

[0037] Please refer to this carefully. Figures 3-7 The connection position of the first connecting strip 503 to the large bag independent spring 501 is far away from the upper and lower ends of the large bag independent spring 501, and the connection position of the first connecting strip 503 to the upper and lower limit bag independent springs 502 is close to the bottom and top ends of the two limit bag independent springs 502 respectively.

[0038] The overall distribution trajectory of the snap-fit ​​independent spring 504 and the small independent spring 505 is a sideways "S" shaped structure. The height of the second connecting strip 506 is less than the height of the snap-fit ​​independent spring 504, and the connection position of the second connecting strip 506 with the small independent spring 505 and the snap-fit ​​independent spring 504 is located in the middle of the small independent spring 505 and the snap-fit ​​independent spring 504.

[0039] In this embodiment: Through the above structure, the tops of the large bag independent spring 501, the upper limiting bag independent spring 502, and the snap-fit ​​bag independent spring 504 can be made independent of each other, thus fully preserving the independent support feature of the bag independent spring 5.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
