Description

Technical Field

[0001] This utility model relates to the field of sofa technology, and in particular to a slow rebound foam sofa. Background Technology

[0002] In modern home life, sofas, as an important furniture component, are receiving increasing attention from consumers regarding their comfort and functionality. To meet the diverse needs of users, sofas with removable seat cushion modules have emerged. This type of sofa, through its structural design of placing seat cushion modules on the sofa frame, allows users to replace seat cushion modules with different materials and patterns according to their preferences, thereby enhancing the flexibility and personalization of sofa use to a certain extent.

[0003] However, existing modular sofas with removable cushions have significant technical flaws. Because they use a structure where cushion modules are placed directly on the sofa frame, the thickness of these modules directly determines the overall seat height. It is well known that cushion thickness is closely related to seating comfort; thicker cushions often provide a softer and more comfortable experience. However, in practical applications, to maintain a low seat height, the cushion modules must be made thin, which undoubtedly sacrifices comfort. This contradiction between cushion thickness and seat height means that existing sofas cannot simultaneously meet users' dual needs for comfortable seating and a suitable seat height, failing to align with modern consumers' pursuit of a high-quality home life. Therefore, further improvements and innovations to the existing sofa structure are urgently needed. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a slow-rebound foam sofa.

[0005] A slow-rebound foam sofa designed for this purpose includes a sofa frame, a movable frame, and foam cushion modules.

[0006] The movable frame is configured to move longitudinally relative to the sofa frame;

[0007] The foam cushion module is mounted on the movable frame;

[0008] The sofa frame is provided with a number of fasteners, which are connected to the movable frame.

[0009] Preferably, the foam cushion module is provided with an extension fixing strap;

[0010] The movable frame is provided with a through slot, and the extended fixing strap extends through the through slot to the space between the sofa frame and the movable frame and is clamped and fixed by both.

[0011] Preferably, the movable frame is provided with an elastic module, and the foam cushion module is disposed on the elastic module.

[0012] Preferably, the elastic module includes sofa springs arranged on the movable frame.

[0013] Preferably, the elastic module includes metal elastic sheets arranged on the movable frame, the metal elastic sheets are provided with Velcro, and the bottom surface of the foam cushion module is provided with an adhesive element that adheres to the Velcro.

[0014] Preferably, the movable frame is provided with several rows of adjustment and locking holes around its perimeter, and each row of adjustment and locking holes includes multiple adjustment and locking holes arranged longitudinally.

[0015] The sofa frame is provided with mounting holes corresponding to each row of adjustment and locking holes, and the fastener passes through the mounting holes and is connected to any one of the adjustment and locking holes.

[0016] Preferably, the foam cushion module includes an outer cover and a first foam layer, a second foam layer and a third foam layer disposed within the outer cover.

[0017] The first foam layer, the second foam layer, and the third foam layer are arranged sequentially from top to bottom.

[0018] Compared with existing technologies, this invention features a longitudinally movable frame relative to the sofa frame, allowing the height of the foam cushion module to be flexibly adjusted according to actual needs. When users desire a thicker, more comfortable foam cushion module to enhance seating comfort, the overall seating height can be appropriately lowered by moving the frame longitudinally, without sacrificing cushion thickness due to height limitations. Conversely, if a lower seating height is desired, a foam cushion module of suitable thickness can be selected while maintaining a comfortable seating height, achieving a balance between comfortable seating and a suitable seating height. Furthermore, several fasteners on the sofa frame connect to the movable frame, preventing frame wobbling during use and ensuring the stability of the entire structure after height adjustment. This significantly enhances the practicality and durability of the sofa, fully meeting the modern consumer's demand for high-quality, multifunctional sofas. Attached Figure Description

[0030] See Figures 1-3 A slow-rebound foam sofa includes a sofa frame 10, a movable frame 20, and a foam cushion module 30; the sofa frame 10 is connected to a backrest (not shown in the figure) and armrests (not shown in the figure); the movable frame 20 is longitudinally movable relative to the sofa frame 10; the foam cushion module 30 is disposed on the movable frame 20; the sofa frame 10 is provided with a plurality of fasteners 50, and the fasteners 50 are connected to the movable frame 20.

[0031] Based on the above embodiments, before adjusting the height, the user needs to disconnect the connection between several fasteners 50 on the sofa frame 10 and the movable frame 20. At this time, the movable frame 20 is no longer constrained by the fasteners and can move freely relative to the sofa frame 10 longitudinally.

[0032] Once the movable frame 20 is released from its constraints, the user can manually adjust it upwards or downwards according to their desired seating height and comfort. Since the foam cushion module 30 is mounted on the movable frame 20, the longitudinal movement of the movable frame 20 will simultaneously adjust the height of the foam cushion module 30. For example, if the user wants a thicker foam cushion module 30 for a softer seating feel, they can adjust the movable frame 20 downwards, increasing the cushion thickness while appropriately lowering the overall seating height; if a lower seating height is desired, the user can adjust the movable frame 20 upwards, selecting a foam cushion module 30 of suitable thickness while ensuring a comfortable seating height.

[0033] After adjusting the height of the movable frame 20 and the foam cushion module 30, the user needs to reconnect the previously released fastener 50 to the movable frame 20. Through the locking connection of the fastener 50, the movable frame 20 and the sofa frame 10 form a stable overall structure, ensuring that the foam cushion module 30 will not shift due to external forces during subsequent use, thus guaranteeing the stability and safety of the sofa after height adjustment.

[0034] Furthermore, to ensure the longitudinal movement stability of the movable frame 20, several sliders can be installed on the movable frame 20, and then corresponding slide rails or grooves can be provided on the sofa frame 10. The sliders are slidably connected to the slide rails or grooves. This sliding connection is a commonly used mechanical structure, which is not shown in the figure.

[0035] See Figure 2 and Figure 3 The foam cushion module 30 is equipped with an extension fixing strap 300; the movable frame 20 is equipped with a through groove 220, and the extension fixing strap 300 extends through the through groove 220 to the space between the sofa frame 10 and the movable frame 20, where it is clamped and fixed. The principle is to achieve a stable connection through mechanical clamping. During installation, the extension fixing strap 300 is passed through the through groove 220, extending between the sofa frame 10 and the movable frame 20. After adjusting the position of the movable frame 20 and locking it with fasteners 50, the sofa frame 10 and the movable frame 20 move closer together, thus forming a clamping force on the extension fixing strap 300, tightly fixing it like a clamp, making the foam cushion module 30 and the movable frame 20 tightly connected. This effectively prevents the foam cushion module 30 from shifting during use. Even under frequent sitting or lying down or large external forces, the clamping and fixing characteristic of the extension fixing strap 300 ensures that the foam cushion module 30 remains in a stable position, improving the user experience.

[0036] See Figure 2 and Figure 3 The movable frame 20 is provided with an elastic module 40, and the foam cushion module 30 is disposed on the elastic module 40.

[0037] See Figure 2 and Figure 3The elastic module 40 includes sofa springs 410 arranged on the movable frame 20. Sofa springs 410 are a conventional design in the sofa industry, and their working principle is based on the elastic deformation characteristics of springs. When a user sits on the foam cushion module 30, pressure is transmitted through the foam cushion module 30 to the sofa springs 410 on the movable frame 20. The sofa springs 410 undergo elastic deformation under pressure, converting the external pressure into their own elastic potential energy for storage. When the user gets up and the pressure disappears, the sofa springs 410 release their elastic potential energy and return to their initial state, thus repeatedly providing support and cushioning for the user's body. The orderly arrangement of multiple sofa springs 410 allows for the dispersion and absorption of pressure from different angles and areas, ensuring uniform force distribution.

[0038] The elastic module 40 includes metal elastic sheets 420 arranged on the movable frame 20. Velcro is attached to the metal elastic sheets 420, and an adhesive element is provided on the bottom surface of the foam cushion module 30 to adhere to the Velcro. When a user sits on the foam cushion module 30, pressure is transmitted through the foam cushion module 30 to the metal elastic sheets 420. Due to its good elasticity, the metal elastic sheets 420 bend and deform under pressure, converting external pressure into elastic potential energy and storing it. When the pressure disappears, the metal elastic sheets 420 release the elastic potential energy and quickly return to their initial shape, continuously providing stable support for the user. The connection between the Velcro and the adhesive element further serves to connect the foam cushion module 30.

[0039] The movable frame 20 has several rows of adjustment locking holes 210 around its perimeter, with each row including multiple vertically arranged adjustment locking holes 210. The sofa frame 10 has mounting holes 110 corresponding to each row of adjustment locking holes 210, and the fastener 50 passes through the mounting holes 110 and connects to any one of the adjustment locking holes 210. The principle is that by changing the connection position of the fastener 50 with different adjustment locking holes 210, the longitudinal movement adjustment of the movable frame 20 relative to the sofa frame 10 is achieved. The multiple vertically arranged holes in each row of adjustment locking holes 210 provide the movable frame 20 with a variety of height adjustment options. When the sofa seat height needs to be adjusted, first remove the fastener 50 that passes through the mounting hole 110 and the adjustment locking hole 210. At this time, the moving frame 20 is unlocked and can move freely in the longitudinal direction. After adjusting the moving frame 20 to a suitable height according to actual needs, select the corresponding position of the adjustment locking hole 210 so that the fastener 50 passes through the mounting hole 110 and is tightly connected to the adjustment locking hole 210, thereby firmly locking the moving frame 20 at the target height.

[0040] The foam seat cushion module 30 includes an outer cover 310 and a first foam layer 320, a second foam layer 330, and a third foam layer 340 disposed within the outer cover 310; the first foam layer 320, the second foam layer 330, and the third foam layer 340 are arranged sequentially from top to bottom. The first foam layer 320, the second foam layer 330, and the third foam layer 340 all use existing cotton materials. The uppermost first foam layer 320 is in direct contact with the human body, and its texture and resilience directly affect the user's initial tactile sensation; the middle second foam layer 330 acts as a transition buffer, evenly distributing the pressure from the human body; the lowermost third foam layer 340 mainly bears the pressure from the upper layers, providing stable support for the entire seat cushion module. The three layers work together to allow the foam seat cushion module 30 to better conform to the curves of the human body during use, improving comfort.

[0041] Furthermore, the first foam layer 320 can be made of memory foam, which has excellent slow rebound properties and can conform to the contours of the human body, effectively dispersing body pressure and giving users a comfortable feel as if they are sinking into a cloud; the second foam layer 330 can be made of high-density polyurethane foam, which has excellent cushioning performance and resilience, and can evenly distribute the pressure applied by the human body to the lower layer to ensure balanced force distribution; the third foam layer 340 can be made of high-hardness support foam, which can provide stable support for the entire seat cushion module, prevent collapse, maintain the stability of the sofa's seat height, and ensure that users always receive comfortable and stable support during use.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
