[0005] In modern life, mattresses are an indispensable piece of bedding. Especially with increasing life pressures, resilient mattresses with elastic components are becoming increasingly popular for relaxation during sleep. Most existing resilient mattresses use individually pocketed springs, each spring packaged in its own pocket, arranged in a pattern, and then covered by a single piece of foam rubber to form the mattress. This type of mattress cannot be disassembled and is difficult to transport. Therefore, mattresses with removable springs have been developed. However, during handling and transportation, the removed springs remain in a released state, taking up considerable space and manpower for transport.

[0006] In order to save manpower and space, springs that can be locked in a compressed state have emerged. However, currently, springs that can be locked in a compressed state need to be compressed and released individually, which is time-consuming, labor-intensive, inconvenient, and inefficient.

[0087] Example 1

[0088] Reference Figure 1-14 This embodiment provides a spring module, including multiple springs 1 arranged in a row. The lower end of each spring 1 is provided with a base 2, and the base is provided with a connector 23. The upper end of each spring is provided with a cover 6. It also includes a third fastener 3, which is located at the upper end of the row of springs. Each spring in the third fastener 3 is provided with a snap fastener 321. The snap fastener 321 of the third fastener 3 engages with the connector 23 on the base 2 to lock the row of springs 1 in a compressed state.

[0089] Specifically, the insert fastener 321 is a slot provided on the third fastener 3, the connector 23 is a hook, the hook has the elasticity of pushing in the horizontal direction, the third fastener 3 is recessed along the direction of spring compression to form a plurality of slots 32, each of the plurality of slots 32 is inserted into the cavity of each spring 1, and the third fastener also includes a connecting part 33 connecting two adjacent slots 32.

[0090] The hooks are symmetrically arranged on both sides of the slot 32. One end of each hook is a fixed end connected to the base, and the other end extends outward from the base as an elastic end. The elastic end of the hook 23 engages with the slot 32, which is preferably formed by multiple folds, allowing for multiple points of engagement with the hook. Thus, each spring has a pair of hooks 23 and a corresponding slot 32 for the third fastener. Each pair of hooks and slots engages with each other, locking each spring in a compressed state. This allows multiple springs to be locked in a compressed state in a row via a third fastener 3. To unlock, pulling the third fastener 3 causes the elastic end of one spring's hook to leave the slot, releasing the engagement. The adjacent springs, under the restoring force of the first spring, release one after another, releasing the entire row or group of springs into an elastic state.

[0091] In order to further lock the compression state of the compression spring, in this embodiment, the third fastener 3 is symmetrically provided with end fasteners 31 at both ends of the spring 1 in the horizontal arrangement direction; and fastening fittings 21 corresponding to the end fasteners 31 are provided on the base 2 at both ends of the row of springs.

[0092] Specifically, the end fastener 31 includes a vertical portion 311 extending axially and a fastening portion 312 parallel to the vertical portion. The fastening portion 312 includes a first limiting portion 3121 that mutually limits the fastening fitting 21 axially, and a second limiting portion 3122 that mutually limits the fastening fitting 21 horizontally. The fastening fitting 21 includes an insertion hole 211 opened in the side wall of the base 2, and the base 2 has a cavity 22 opened inside the side wall. The fastening portion 312 is inserted into the insertion hole 211, and the first limiting portion 3121 is vertically and vertically limited by the hole wall of the insertion hole 211 along the axial direction, while the second limiting portion 3122 is horizontally limited by the inner wall of the cavity 22 of the base to fasten the third fastener 3 to the base 2.

[0093] The end fastener also includes a release handle 313. In the compressed state, pulling away the release handle 313 causes the fastening part 312 to be pulled out from the insertion hole 211, thus releasing the fastening between the third fastener 3 and the base 2.

[0094] In this embodiment, when the user needs to release the compressed springs, pulling the third fastener 3 releases the third fastener 3 from the end fastener 31 at one end of the base 2, and also releases the plug 321 on the third fastener 3 from the connector 23 on the base 2. This releases each individual compressed spring in the row. The restoring force of this individual compressed spring simultaneously pulls the plug 321 on the third fastener 3 of the adjacent spring to release from the connector 23 on the base 2, allowing adjacent springs to be released sequentially. This eliminates the need for manual release, reducing the number of releases, improving efficiency, and making it convenient for the user. Furthermore, since the entire row of compressed springs is released sequentially, the force of the entire row of springs is reduced to the force of a single spring, ensuring good safety.

[0095] In order to stably apply pressure to the upper end of the spring by the third fastener 3, the upper end of the slot of the third fastener 3 is designed to be cross-shaped, and the pressing part extends out in the vertical direction of the third fastener 3. In this way, the upper end of the spring is subjected to the pressure of the third fastener 3 in the horizontal and vertical directions, and the spring is balanced and stable when compressed.

[0096] In this embodiment, as Figure 2-3 , Figure 6-7 , Figure 10-11 As shown, the third fastener 3 is elongated, and the projected shape of the first part can be as follows: Figure 6-7 As shown, it is a strip with the same width as the third fastener. To further increase the locking stability, the slot can also be... Figure 10-11 As shown, a circular ring with the same radius as the spring cavity. It can also be like... Figure 2-3 As shown, the upper end of the slot is cross-shaped, which presses more forcefully against the upper end of the spring.

[0097] Example 2

[0098] Reference Figure 15-19 The difference between this embodiment and embodiment 1 is that the spring module in this embodiment includes two layers. The spring 1 includes a first spring 11 and a second spring 12. One end of the first spring 11 and the second spring 12 along the axial direction are respectively installed on the upper and lower sides of the intermediate connecting seat 4. The intermediate connecting seat 4 connects multiple first springs 11 into a row to form a first layer and connects multiple second springs 12 into a row to form a second layer. The two ends of the intermediate connecting seat 4 are respectively provided with connectors 43 for each spring.

[0099] It also includes two third fasteners 3, which are respectively located at the other end of the first spring 11 and the second spring 12 along the axial direction. Each third fastener 3 has a corresponding insert fastener 321 on each spring. The insert fastener 321 of the third fastener 3 is engaged with the connector 43 on the intermediate connecting seat 4 to lock both layers of the spring 1 in a compressed state.

[0100] Specifically, the insert fastener 321 is a slot provided on the third fastener 3, and the connector 43 is a hook with elasticity that pushes horizontally. The third fastener 3 forms a slot 32 along the square recess of the spring compression, and the slot 32 is inserted into the cavity of the spring 1. The third fastener also includes a connecting part 33 connecting two adjacent slots. The hooks are symmetrically arranged facing each other, with one end of the hook being a fixed end and the other end being a cantilevered elastic end. The slot 32 engages with the elastic end of the hook, and the engagement can be released by compression or oblique force. Each set of hooks and slots engages with each other, locking the springs in a row in a compressed state. Pulling the third fastener 3 causes the elastic end of the hook to leave the slot, releasing the engagement between the hook and the slot.

[0101] In order to further lock the compression state of the compression spring, in this embodiment, the third fastener 3 is symmetrically provided with end fasteners 31 at both ends of the spring horizontal arrangement direction, and the two sides of the intermediate connecting seat 4 are respectively provided with end fasteners 41 corresponding to the end fasteners 31.

[0102] Specifically, the end fastener 31 includes a vertical portion 311 extending axially and a fastening portion 312 parallel to the vertical portion. The fastening portion 312 includes a first limiting portion 3121 that mutually limits the fastening fitting 41 axially, and a second limiting portion 3122 that mutually limits the end fastening fitting 41 horizontally. The end fastening fitting 41 includes an insertion hole 411 opened in the side wall of the intermediate connecting seat 4, and the intermediate connecting seat 4 also has a cavity 42 opened inside the side wall. The fastening portion 312 is inserted into the insertion hole 411, and the first limiting portion 3121 is vertically and vertically limited to the hole wall of the insertion hole 411 axially, while the second limiting portion 3122 is horizontally limited to the inner wall of the cavity 42 of the intermediate connecting seat to fasten the third fastener 3 to the intermediate connecting seat.

[0103] The fastener 31 also includes a release handle 313, which has a similar function and structure to that of Embodiment 1 and will not be repeated here. The rest is the same as that of Embodiment 1 and will not be described in detail here.

[0104] When the user needs to release the compression spring, pull the upper and lower third fasteners 3 to release the end fastener 41 at one end of the third fastener 3 and the connector 43 on the intermediate connecting seat 4. This releases the first compression spring in the row. The restoring force of the first compression spring simultaneously pulls the connector 321 on the third fastener 3 of the adjacent spring to release the connector 23 on the base 2. The adjacent springs are released one after another without the need for manual release, reducing the number of releases, improving release efficiency, and making it convenient for users. Moreover, the entire row of compression springs is released one by one, reducing the elasticity of the entire row of springs to the elasticity of a single spring, which ensures good safety.

[0105] Example 3

[0106] Reference Figure 20-28 This embodiment provides a spring module including multiple springs. The spring 1 includes a first spring 11 and a second spring 12. One end of the first spring 11 and the second spring 12 along the axial direction are respectively installed at the upper and lower ends of an intermediate connecting seat 4. The intermediate connecting seat 4 connects the multiple springs into a group. Insertion holes 42 are provided on both the upper and lower sides of the intermediate connecting seat 4. The other end of the first spring 11 and the second spring 12 is provided with an insertion cavity that can be retracted and extended along the radial direction.

[0107] Specifically, the upper end of the first spring 11 is flexible or has weak support. A second upper cover 14 is also provided on the top of the first spring 11. The second upper cover 14 forms a first cavity 141 along the axial inward direction. The bottom of the first cavity 141 is provided with a cavity bottom 1412 and an insertion hole 1411. The convex cavity body is rigid. The bottom of the second spring 12 is provided with a bottom cover 5. The bottom cover 5 body is rigid. The bottom cover 5 is provided with a second cavity 51. The second cavity 51 is provided with a cavity bottom 512 and an insertion hole 511.

[0108] A third fastener 3 is provided at the outer end of the first and second springs respectively. The third fastener has a shoulder 37, which abuts against the bottom of the first and second cavities 1412 and 512. The third fastener 3 is provided with an insertion block 34 that can pass through the cavity through holes 511 and 1411. The insertion block 34 passes through the cavity through holes 511 and 1411 and is inserted into the intermediate connecting seat insertion hole 42. The shoulder 37 of the third fastener abuts against the bottom of the first and second cavities 1412 and 512, forming the third fastener. The first spring 11 and the second upper cover 14 are fastened together with the intermediate connecting seat 4. The cavity is an integral whole, or it can be formed by multiple spaced barriers. One end of the barrier is connected to the second upper cover, or the bottom cover or the base, and the other end is an elastic end. The insert block 34 pushes against the elastic end of the barrier, so that the cavity is squeezed radially outward, making the cavity tightly abut. The insert block 34 abuts against the insertion hole 42 of the intermediate connecting seat, thereby locking the first spring 11 and the second spring 12 as a group in a compressed state.

[0109] Using external force to pull the third fastener 3 causes the plug 34 to be pulled out of the socket 42 of the intermediate connecting seat, releasing a single compression spring. The third fastener 3, pushed by the spring, pulls the adjacent plug out of the socket, releasing the adjacent spring. In this way, the entire row or group of springs is released one after another.

[0110] For a tight fit, the insert 34 passes through the through holes 511 and 1411 and is inserted into the insertion hole 42. The insertion hole 42 is reduced in radius along the insertion direction to form a slope, or the outer end of the insert 34 gradually increases.

The multiple spring covers 6 are connected or integrally formed, and the multiple springs 1 are connected in a row or group. The upper cover is provided with a socket 15, and the other end of each spring is provided with a cavity.

[0113] The insertion cavity can be a base 14 located at the bottom of the spring 1, the base 14 forming a protrusion 141 along the axial inward direction, and the top of the protrusion 141 having the insertion hole 1411; alternatively, the insertion cavity 511 can be located on the second upper cover 5, such as... Figure 31 , 32 The second upper cover 5 is provided with a protrusion 51 corresponding to the cavity of each spring in a group or row. The protrusion 51 of the top cover is inserted into the cavity of the spring 1, and the top of the protrusion 51 is provided with the insertion hole 511.

[0114] It also includes a third fastener 3, which is located at the upper end of the second upper cover along the axial direction of the spring 1. The third fastener 3 is provided with a plug block 34 corresponding to the insertion cavity 511 and the insertion hole 1411. The insertion cavity is inserted into the insertion hole 15, and the plug block 34 is inserted into the insertion cavity 511 or 1411, pressing the insertion cavity 511 or 1411 radially outward so that the insertion cavity abuts against the insertion hole 15, thereby locking the spring 1 in a row or group in a compressed state. Using external force to pull the third fastener 3 causes the plug block 31 to be pulled out of the insertion cavity, releasing the entire row or group of springs. The rest is the same as in embodiment 3, and will not be described again here.

[0115] Example 5

[0116] Reference Figures 33-44 The present invention also provides a spring module, including multiple springs, wherein one end of the multiple springs 1 is mounted on a base 2 along the axial direction, and the base 2 connects the multiple springs 1 into a spring group arranged in a horizontal and vertical alignment; the top cover of the spring 1 is provided with an expansion sleeve 13 for inserting a connector 35, the expansion sleeve 13 having elasticity that contracts radially, and the bottom of the spring is provided with a connector cavity.

[0117] It also includes a third fastener 3. In this embodiment, the third fastener 3 is a horizontally and vertically intersecting buckle. The third fastener 3 is located at the upper end of the row or group of springs 1 along the axial direction. The third fastener 3 is provided with a plug-in 35 corresponding to the spring group 1. The plug-in 35 of the third fastener 3 is inserted into the expansion sleeve 13 inside the spring 1 through the insertion hole 15 of the spring cover. The cooperation between the expansion sleeve 13 and the plug-in 35 inserts the third fastener 3 onto the spring group 1. Figure 38 , 39 As shown; the insertion part 35 of the third fastener or the expansion sleeve 13 of the upper cover is pressed and abutted against the insertion cavity of the base in a radially outward direction to lock the spring assembly in a compressed state. The expansion sleeve 13 in the upper cover serves as both a receiving part of the third fastener and a second fastener inserted into the connector of the base. It is fastened to the base alone or together with the third fastener. In this embodiment, the connector on the base is an insertion cavity.

[0118] Specifically, in this embodiment, the spring 1 is mounted on one end of the base 2 and has a convex cavity 16 along the axial direction as an insertion cavity. The convex cavity 16 gradually narrows in the height direction to form a conical cavity. The expansion sleeve 13 gradually widens in the insertion direction, so that the outer wall of the expansion sleeve 13 cooperates with the inclined surface of the inner wall of the convex cavity 16 to lock it in place.

[0119] Preferably, the plug-in part 35 on the third fastener includes a connecting part 351 and a plug-in part 352. The plug-in part 351 is an inverted cone shape with a gradually narrowing radius along the direction of insertion into the convex cavity 16. The upper diameter of the plug-in part 351 is larger than that of the connecting part 351, so that the plug-in part 352 is not easy to come out after passing through the expansion sleeve 13 and engaging with the expansion sleeve in the vertical direction.

[0120] When the spring module of this embodiment is released, since the top cover and base are connected to the spring, they will be pulled by the elastic deformation of the spring, causing the third fastener 3 to move the expansion sleeve 13 away from the convex cavity 16, or the upper pressing plug 352 to move away from the lower end face of the convex cavity 16, so that the spring 1 is released. The restoring force of the spring release 1 pulls the third fastener 3 again, thereby causing the adjacent spring 1 to be released. In this way, the adjacent springs in the horizontal and vertical directions are released, until the entire set of springs 1 are released one after another.

[0121] To facilitate the insertion of the expansion sleeve 13 into the convex cavity 16, the top radius of the convex cavity 16 gradually widens to form an inverted conical cavity, and the inclined surface of the inverted conical cavity is used to guide the expansion sleeve 13.

[0122] Example 6

[0123] Reference Figures 45-47In this embodiment, the third fastener 3 has a connecting part, which is an elastic stretch band or flexible band 36, between two adjacent springs and is longer than the distance between the ends of the two springs. For a single-layer spring, the third fastener 3 can be one, connected to the top or bottom of the spring. In this embodiment, it is a double-layer spring, and there are two third fasteners 3, which are connected to the top and bottom of the spring respectively.

[0124] The third fastener 3 is provided with mounting holes corresponding to a row or column of springs for inserting a fastener to connect the third fastener 3 to one end of the spring. Alternatively, the third fastener may have a fastener corresponding to the spring position that connects to the end face of the spring. Similar to the above embodiment, the other end of the spring is provided with a connector that engages with the fastener. This will not be repeated here. The difference is that when two adjacent springs are in the same released or compressed state, the connecting part 36 between the two springs is in the relaxed state. When one of the two adjacent springs is in the elastic state and the other is in the compressed state, the elastic stretching band or flexible band 36 connecting the two springs is subjected to the elastic tension of one end of the spring from the relaxed state to the tensioned state. The function of the excessively long elastic stretch band or flexible band 36 is that, during the process of the spring releasing from the compressed state to the elastic state, the excessively long elastic stretch band or flexible band 36 will only pull the next set of springs to unlock after being stretched and tightened. This allows the springs to unlock sequentially with a certain time difference, which can adjust the time interval between the release of adjacent springs. Alternatively, pulling the third fastener 3 at one time can release only one spring, and the release of adjacent springs requires operating the third fastener again.

[0125] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
