[0002] In modern life, mattresses are an essential piece of furniture in people's bedding. As people's life pressures increase, spring mattresses with elastic components in the middle are becoming increasingly popular in order to relax during sleep. Existing spring mattresses mostly use independent pocket springs as the elastic components. Each spring is individually packaged in a spring bag, which is then arranged in a pattern and covered with a whole piece of foam rubber to form the entire spring mattress. This type of spring mattress is difficult to disassemble and transport, making it difficult to disassemble and assemble the bed during moving or other processes that require moving the bed. Furthermore, the fabric and cushioning of the mattress cannot be disassembled and cleaned for a long time, which leads to the breeding of mites and affects human health. Furthermore, when the mattress is compressed, the springs cannot move up and down completely independently, and cannot conform to the body's curves, thus affecting comfort.

[0003] Incorporating detachable elastic components into a mattress allows it to be disassembled when needed, reducing the burden of transporting the mattress and allowing for regular cleaning and replacement of the furniture. However, existing detachable elastic mattresses suffer from weak spring stability and a loose detachable connection to the mounting frame, resulting in an unstable mattress during use and poor durability, shortening the mattress's lifespan.

[0063] Example 1

[0064] Reference Figure 1-10 This embodiment provides a spring connection structure, including a mounting frame and an elastic module 2. The mounting frame includes 12 mounting frames 1, each mounting frame 1 is provided with two longitudinal extension parts 10 and a connecting part 11, and the connecting part 11 is provided between the two longitudinal extension parts 10, and between the longitudinal extension part 10 and the side beam of the mounting frame 1; the elastic module 2 includes an upper cover 22 and a base 21, the upper cover 22 serves as a supporting surface to support the pressure on the elastic module, and the base 21 is connected to the mounting frame as a connecting end, the base 21 of the elastic module 2 is provided with slides 211 parallel to each other, and the longitudinal extension part 10 is provided with three mounting parts 101, each mounting part 101 includes a mounting slide rail and a positioning part to locate the installation position of the elastic module 2, and the slide rail 211 cooperates with the mounting slide rail to allow the elastic module 2 to be detachably mounted on the mounting frame 1.

[0065] Specifically, in this embodiment, the longitudinally extending portion 10 of the mounting frame 1 is a longitudinally extending profile. Each of the three mounting portions 101 has a section of profile that protrudes laterally along the width, forming a T-shaped slide 101.1 that serves as the mounting rail. Two retaining slots 211 are provided beneath the elastic module base 21, which mate with the aforementioned transverse protrusions and serve as guideways. These retaining slots 211 engage with the T-shaped slide 101.1 formed by the transverse protrusions in a vertical and widthwise manner. This prevents the elastic module 2 from easily falling off after installation, further strengthening the elastic pad.

[0066] In this embodiment, the elastic module 2 is an inverted cone-shaped spring, so the area of ​​the elastic module's upper cover 22 is larger than the area of ​​the base 21. To ensure that the upper covers 22 of each elastic module 2 are not squeezed and affected by each other after installation, in this embodiment, when positioning the T-shaped rails 101.1 on the profile, the distance between two adjacent T-shaped rails 101.1 on the mounting frame is greater than the size of the elastic module's upper cover 22. This allows each elastic module 2 to be installed vertically on the mounting frame after installation, preventing squeezing and tilting, which would result in unstable force on the elastic module 2 and weaken the elastic pad.

[0067] In order to allow the limiting slot 211 of the elastic module base 21 to accurately slide into the T-shaped slide rail 101.1, in this embodiment, a sliding area 101.3 is provided at one end of the T-shaped slide rail 101.1 to cooperate with the slide rail 211. The width of the sliding area 101.3 is smaller than the width of the T-shaped slide rail 101.1. The limiting slot 211 can be placed in the sliding area 101.3 from the vertical direction and then slide horizontally into the T-shaped slide rail 101.1.

[0068] When installing the elastic module 2, the limiting slot 211 under the elastic module base 21 is vertically placed on the sliding area 101.3, and then slid horizontally toward the T-shaped slide rail 101.1 on the profile. When it is positioned by the positioning portion, the installation is complete. Similarly, the elastic module 2 is installed on each installation slide rail 101.1 of the mounting frame in sequence.

[0069] In this embodiment, the limit slot 211 cooperates with the T-shaped slide rail 101.1 in the vertical direction and the width direction of the limit slot 211 to limit the position, while being movable in the horizontal sliding direction, so that the elastic module 2 can be detachably mounted on the mounting frame 1. When the elastic module 2 needs to be removed, it can be slid out by applying external force in the direction opposite to the sliding direction.

[0070] To further enhance the secure installation of the elastic module 2, in this embodiment, an opening 210 is provided in the center of the base 21 of the elastic module. A connector 101.2 is positioned between the T-shaped rails 101.1. The connector 101.2 includes a fixed end and an elastic end. The fixed end is fixedly connected to the profile, and the elastic end has an inclined surface that gradually increases in height as it slides into the mounting rails 101.1 along the guide rails 211. As the elastic module 2 is slid into the T-shaped rails 101.1, the elastic end of the connector 101.2 engages with the opening 210 in the base of the elastic module, further securing the elastic module 2 to the mounting frame. At this point, the elastic end of the connector 101.2 is in its initial position.

[0071] To facilitate removal of the elastic module 2, in this embodiment, the elastic end of the connector 101.2 can be swung from its initial position to a second position under the action of an external force. When the elastic end is in the second position, the elastic end is released from its restraining engagement with the opening. To remove the elastic module 2, manually pressing the elastic end causes it to swing from its initial position to the second position, releasing its restraining engagement with the opening 210 of the elastic module base.

[0072] In this embodiment, the connector 101.2 also serves as a positioning portion to determine whether the elastic module 2 is installed in place. When the elastic module 2 slides to a limit fit with the connector 101.2, it is installed in a predetermined position.

[0073] Furthermore, to facilitate transportation of the mounting frame and save space, in this embodiment, the mounting frame 1 is foldable in the longitudinal direction. The folding method is not limited. Connectors can be provided on the side beams of the mounting frame for hinge connection, or hinge connection can be used. The side beams of the mounting frame 1 in the width direction are provided with limiting protrusions 12, and the side beams on the other side opposite thereto are provided with limiting grooves 13 corresponding to the positions of the limiting protrusions 12. The mounting frame 1 is detachably connected in the width direction.

[0074] In this embodiment, the six mounting frames 1 are folded and connected in the length direction to form a foldable assembly, and two foldable assembly are connected in the width direction of the mounting frames 1 to form a rectangular mounting frame.

[0075] When transporting or moving the mounting frame, the mounting frame is first disassembled into two foldable parts in the width direction, and then the mounting frames 1 of the foldable parts are folded together in the length direction, which can save placement space and facilitate transportation and moving.

[0076] In this embodiment, in order to ensure that the elastic module 2 and the mounting frame 1 can be evenly stressed when the elastic pad is in use, the connecting portion 11 is a symmetrically arranged mesh structure.

[0077] Example 2

[0078] Reference Figure 11-14, this embodiment provides a spring connection structure, including a mounting frame and an elastic module 2, the mounting frame includes 14 mounting frames 1, the mounting frame 1 is provided with a longitudinal extension portion 10 and a connecting portion 11, the connecting portion 11 is provided between the two longitudinal extension portions 10, and between the longitudinal extension portion 10 and the side beam of the mounting frame 1; the elastic module 2 includes an upper cover 22 and a base 21, the upper cover 22 serves as a supporting surface to support the pressure on the elastic module, the base 21 is connected to the mounting frame as a connecting end, the base 21 of the elastic module is provided with slides parallel to each other, the longitudinal extension portion 10 is provided with three mounting portions 101, each of the mounting portions includes a mounting slide rail and a positioning portion to position the installation position of the elastic module, the slide rail 211 is limited by the mounting slide rail to allow the elastic module 2 to be detachably mounted on the mounting frame 1.

[0079] Specifically, in this embodiment, each of the three mounting portions 101 has a T-shaped rail 101.1 formed along vertical projections on either side of the mounting portion at one end. Two strip-shaped slots 211 are provided below the elastic module base 21, which mate with the aforementioned vertical projections and serve as guideways. These strip-shaped slots 211 engage with the T-shaped rails 101.1 formed by the vertical projections in a position-limiting manner along the vertical direction and the width of the strip-shaped slots 211. This prevents the elastic module 2 from easily falling off after installation, further strengthening the elastic pad.

[0080] In this embodiment, the elastic module 2 is an inverted cone-shaped spring, so the area of ​​the upper cover 22 of the elastic module 2 is larger than the area of ​​the base 21. To ensure that the upper covers 22 of each elastic module 2 will not be squeezed and affect each other after the elastic modules 2 are installed, in this embodiment, when positioning the T-shaped rails 101.1, the distance between two adjacent T-shaped rails 101.1 on the mounting frame is greater than the size of the elastic module upper covers 22. After installation, each elastic module 2 is installed vertically on the mounting frame, and will not squeeze each other and cause tilting, resulting in unstable force on the elastic module 2 and a weak elastic pad.

[0081] To ensure that the strip-shaped slot 211 of the elastic module base 21 accurately fits into the T-shaped rail 101.1, in this embodiment, a sliding area is provided at one end of the T-shaped rail 101.1 to accommodate the strip-shaped slot 211. This sliding area is a groove 101.3, which is wider than the distance between the two mounting rails. After the strip-shaped slot 211 is vertically placed in the groove 101.3, it slides horizontally into the T-shaped rail 101.1.

[0082] In order to allow the strip slot 211 to slide into the T-shaped slide rail 101.1 more smoothly, in this embodiment, the T-shaped slide rail 101.1 is provided with a tip portion at one end close to the sliding area groove 101.3 to facilitate the strip slot 211 of the elastic module to slide into.

[0083] When installing the elastic module 2, place the strip-shaped retaining groove 211 under the elastic module base 21 vertically within the sliding area groove 101.3. Then, slide the elastic module 2 horizontally toward the vertically raised T-shaped rail 101.1 until the elastic module 2 is pressed against the groove wall 101.2. The elastic module 2 is then installed in place. In this case, the retaining portion is the groove wall 101.2 at one end of the groove in the direction of sliding the installation rail. Similarly, install the elastic module 2 onto each T-shaped rail 101.1 of the mounting frame in sequence.

[0084] In this embodiment, the strip-shaped slot 211 is engaged with the T-shaped guide rail 101.1 in the vertical direction and in the width direction of the strip-shaped slot 211, while being movable in the horizontal sliding direction, so that the elastic module 2 can be detachably mounted on the mounting frame 1. When the elastic module 2 needs to be removed, it can be slid out by applying external force in the direction opposite to the direction in which it was slid in.

[0085] In this embodiment, the seven installation frames 1 are connected in the length direction to form a spliced ​​body, and the two spliced ​​bodies are connected in the width direction of the installation frame 1 to form a rectangular installation frame.

[0086] When transporting or moving the mounting frame, the mounting frame is first disassembled into two spliced ​​parts in the width direction, which can save placement space and facilitate transportation and moving. The rest is the same as in Example 1 and will not be repeated.

[0087] Example 3

[0088] Reference Figure 15-22 This embodiment provides a spring connection structure, including a mounting frame and an elastic module 2. The mounting frame includes 12 mounting frames 1, each of which is provided with two longitudinal extensions 10 and a connecting portion 11. The connecting portion 11 is provided between the two longitudinal extensions 10 and between the longitudinal extension 10 and the side beam of the mounting frame 1; the elastic module 2 includes an upper cover 22 and a base 21; the base 21 of the elastic module is provided with mutually parallel strip-shaped card slots 211 as slideways, and the longitudinal extension 10 is provided with three mounting portions 101, each of which includes a mounting slide rail and a positioning portion to locate the installation position of the elastic module 2;

[0089] To further enhance the stability and durability of the elastic pad during use, in this embodiment, the upper covers 22 of three elastic modules 2 are connected together to form a linked spring. The elastic module 2 includes a base 21, an upper cover 22, a connecting strap 23, and a spring 24 that abuts the base 21 and the upper cover 22. The elastic module 2 is an inverted cone spring with an inverted cone shape. The area of ​​the upper cover 22 is larger than the area of ​​the base 21. The connection between the upper covers of the multiple elastic modules 2 is a flexible connection. Connecting the upper cover 22 of an elastic module with the upper cover 22 of another elastic module to form a linked spring can make it more stable when subjected to force and have better load-bearing capacity. This can improve the stability and durability of the elastic pad during use, increase the service life of the elastic pad, and improve the elastic load-bearing capacity.

[0090] To ensure that the coupling springs on different mounting frames 1 form corresponding coupling structures, in this embodiment, the coupling springs on different mounting frames 1 are detachably connected in the width direction. After installation, the two coupling springs are connected together in the width direction to form a complete coupling spring, which can further improve the stress stability and load-bearing capacity compared to a single coupling spring. When disassembly is required, the connection can be disassembled.

[0091] In this embodiment, to coordinate with the aforementioned coupling springs, the longitudinally extending portion 10 of each mounting frame 1 has three mounting portions 101 for mounting the inverted-cone elastic modules 2. Each mounting portion 101 has a vertical protrusion along either side of the mounting portion, forming a T-shaped slide rail 101.1 serving as the mounting rail. Two strip-shaped slots 211 are provided beneath the base 21 of each inverted-cone elastic module of the coupling springs, which cooperate with the aforementioned vertical protrusions and serve as slide rails. The strip-shaped slots 211 are positioned vertically and widthwise with the T-shaped slide rails 101.1 formed by the vertical protrusions. This prevents the elastic modules 2 from easily falling off after installation, further strengthening the elastic pad.

[0092] At the same time, since each inverted cone elastic module 2 of the coupling spring is in an inverted cone shape, the width of the upper cover 22 of each inverted cone elastic module of the coupling spring is greater than the width of the base 21. In order to ensure that after installation, the upper cover 22 of each inverted cone elastic module of the coupling spring will not squeeze each other and tilt. In this embodiment, when setting the position of the T-shaped slide rail 101.1, the distance between two adjacent T-shaped slide rails 101.1 of the mounting frame is greater than the size of the upper cover 22 of the inverted cone elastic module. After installation, the coupling spring is vertically installed on the mounting frame and will not tilt due to the mutual squeezing of the inverted cone elastic modules. At the same time, the coupling springs on different mounting frames will not squeeze each other, resulting in unstable force on the elastic module 2 and making the elastic pad unstable.

[0093] To ensure accurate alignment of the strip slot 211 of the elastic module base 21 with the T-shaped rail 101.1, in this embodiment, a sliding area is provided at one end of the T-shaped rail 101.1 to accommodate the strip slot 211. This sliding area is a groove 101.3, which is wider than the distance between the two mounting rails. After the strip slot 211 is vertically placed in the groove 101.3, it slides horizontally into the T-shaped rail 101.1.

[0094] In order to allow the strip-shaped slot 211 to slide into the T-shaped slide rail 101.1 more smoothly, in this embodiment, the T-shaped slide rail 101.1 is provided with a tip portion near one end of the sliding area to facilitate the sliding of the elastic module into the strip-shaped slot 211.

[0095] When installing the coupling springs, vertically place the strip-shaped slots 211 under each elastic module base 21 in its corresponding groove 101.3. Then, slide the module horizontally toward the vertically raised T-shaped rail 101.1 until the elastic module 2 is pressed against the groove wall 101.2. The elastic module 2 is now in place. At this point, the locating portion is the groove wall 101.2 at one end of the groove, in the direction of the T-shaped rail. Similarly, each coupling spring is sequentially installed on each T-shaped rail 101.1 of the mounting frame.

[0096] In this embodiment, the strip-shaped slot 211 is engaged with the T-shaped guide rail 101.1 in the vertical direction and in the width direction of the strip-shaped slot 211, while being movable in the horizontal direction of the sliding direction, so that the elastic module 2 can be detachably mounted on the mounting frame 1. When the elastic module 2 needs to be removed, it can be slid out by applying external force in the direction opposite to the direction in which it was slid in.

[0097] To further enhance the secure installation of the elastic module 2, in this embodiment, an opening 210 is provided in the center of the base 21 of each inverted-cone elastic module of the coupling spring. A connector 101.4 is provided between the T-shaped slide rails 101.1. The connector 101.4 includes a fixed end and an elastic end. The fixed end is fixedly connected to the groove wall 101.2 of the longitudinal extension portion. The elastic end of the connector 101.4 is engaged with the opening 210 of the inverted-cone elastic module base. When the inverted-cone elastic module 2 is slid horizontally toward the T-shaped slide rail 101.1, the elastic end penetrates the opening 210 of the inverted-cone elastic module base and engages with the opening 210. At this point, the elastic end of the connector 101.4 is in its initial position, further enhancing the secure installation of the elastic module 2 and the mounting bracket.

[0098] At the same time, to facilitate the removal of the elastic module 2, in this embodiment, the elastic end of the connector 101.4 can be swung from the initial position to a second position under the action of an external force. When the elastic end is in the second position, the elastic end is released from the retaining engagement with the opening 210.
