Example 1

1-14, this embodiment provides an elastic module, comprising a plurality of pre-compressed springs 1, wherein the pre-compressed springs 1 are waisted springs with both ends larger than the middle, and a cloth cover is wrapped around the outside of the spring. In the middle of the pre-compressed spring 1, a connector 2 is provided on the outside of the wrapped cloth cover. The elastic module also includes a lap joint 3, which is formed by splicing a plurality of lap elements 31 front and back. The plurality of pre-compressed springs 1 are in contact or close to each other, and the connector 2 of the pre-compressed spring 1 is connected to the lap element 31 of the lap joint 1. Each lap element 31 on the lap joint 3 is connected to the pre-compressed spring 1, and the lap joint 3 is connected to the pre-compressed spring 1 by connecting the pre-compressed springs 1 in series into rows and connecting two adjacent rows of pre-compressed springs 1.

Specifically, in this embodiment, a bayonet 21 is provided on two opposite sides of the connecting member 2 as a first connecting structure. The bayonet 21 includes a connecting arm 21.1 and a locking portion 21.2. The connecting arm 21.1 is fixedly connected to the side of the connecting member 2 to fix the bayonet 21 on the connecting member 2. The width of the connecting arm 21.1 is smaller than the width of the locking portion 21.2, so that the bayonet 21 forms a T-shaped bayonet 21.

The bridge element 31 is in an elongated shape, and a retaining member 310 is provided on both sides of the bridge element 31 to limit the position of the T-shaped bayonet 21 as a second connecting structure. The retaining member 310 is fixed to both sides of the bridge element 31. Each retaining member 310 includes a retaining notch 310.1 for inserting the T-shaped bayonet, a retaining portion 310.2 extending inwardly from both sides of the bridge element 31 to form a horizontal retaining portion 21.2, and a retaining structure 310.3 on the right retaining portion 310.2 to vertically retain the bayonet 21 inserted into the retaining notch 310.1. As a simple alternative to this embodiment, the retaining structure can also be provided on the left retaining portion 310.2, or a retaining structure 310.3 can be provided on both sides of the retaining portion 310.2.

The locking structure 310.3 is elastic, and the locking member 310 also includes a releasing member 310.4 for releasing the locking pin limit. The releasing member 310.4 is connected to the locking structure 310.3 through a cantilevered arm. The releasing member 310.4 pushes and pulls the limiting part 310.2 to drive the locking structure 310.3 to lock or leave the connecting arm 21.1 of the T-shaped locking pin 21 to achieve the limitation and release of the T-shaped locking pin 21.

When the pre-compression spring 1 is connected, pressing the release piece 310.4 pulls open the right limit part 310.2 to form a space in the middle of the two side limit parts 310.2 to engage the connecting arm 21.1 of the T-shaped pin 21. At this time, the first connecting structure T-shaped pin 21 on the pre-compression spring connector is inserted from above into the locking notch 310.1 on the second connecting structure locking piece 310 on the lap element. After insertion, the locking part 21.2 is horizontally limited by the limiting part 310.2, and the connecting arm 21.1 is located in the middle of the two side limit parts 310.2. Releasing the release piece 310.4 allows the locking structure 310.3 to limit the connecting arm 21.1 in the vertical direction, so that the locking pin 21 and the locking piece 310 cooperate to achieve the connection between the lap element 31 and the connecting piece 2.

By analogy, the T-shaped pin 21 of each pre-compression spring connector is inserted into the retaining members 310 on both sides of the lap element 31 of the lap joint 3 using the above method. The lap joint 31 has multiple lap elements 31. The multiple lap elements 31 connect the pre-compression spring 1 to the lap joint 3 at the same time, thereby connecting the pre-compression spring 1 in series into a row. At the same time, retaining members 310 are set on both sides of the lap element 31. The retaining members 310 on both sides are connected to the T-shaped pin 21 on the pre-compression spring 1 connector, thereby connecting the pre-compression springs 1 in two adjacent rows.

In this embodiment, a plurality of overlapping elements 31 are spliced together front and back to form a overlapping part 3, a plug-in 311 is provided at the front end of the overlapping element 31, and a socket 312 is provided at the rear end of the overlapping element 31. The plug-in 311 at the front end of the rear overlapping element 31 is inserted into the socket 312 at the rear end of the front overlapping element 31 to realize the splicing of two adjacent overlapping elements 31.

More specifically, the thickness of the plug-in 311 at the front end of the overlapping element 31 is slightly thinner than the thickness of the overlapping element 31, and an elastic limiter 311.1 is provided on one side of the plug-in 311. The elastic limiter 311.1 is elastic and can be pressed from a first position protruding from the side of the plug-in 311 to a second position flush with the side of the plug-in 311. The front half of the elastic limiter 311.1 is a downward slope along the direction in which the plug-in 311 is inserted into the socket 312. The thickness of the socket 312 at the rear end of the overlapping element 31 is slightly thicker than the thickness of the overlapping element 31, and a slot 312.1 for inserting the plug-in 311 is provided in the middle of the thickness direction of the socket 312. The thickness of the slot 312.1 is greater than the thickness of the plug-in 311, and less than the overall thickness of the plug-in 311 and the elastic limiting member 311.1. A limiting structure that can limit the elastic limiting member 311.1 is provided in the slot 312.1. The limiting structure can be a space provided on the inner wall of the slot 312.1 for the elastic limiting member 311.1 to pop out.

When multiple overlapping elements 31 are spliced together to form a overlapping element 3, the plug 311 at the front end of the rear overlapping element 31 is inserted into the slot 312.1 of the socket 312 at the rear end of the front overlapping element. During insertion, the elastic limiting member 311.1 is pressed by the inner wall of the slot 312.1 and gradually becomes flush with the side of the plug 311, allowing it to be inserted into the slot 312.1. When the plug 311 is inserted into the slot 312.1 until the elastic limiting member 311.1 pops out and is restrained by the inner wall of the slot 312.1, the front and rear overlapping elements 31 are connected. To adapt to application scenarios such as hospital beds that require a raised bedside, as a simple alternative to this embodiment, the plug 311 can also rotate around the socket 312 to allow the elastic module to be folded and raised.

The number of lap elements 31 in the lap joint 3 can be adjusted according to the size requirements of the elastic module. In this embodiment, the lap joint 3 has 20 lap elements 31 spliced together front to back in the above manner, and then the pre-compressed springs 1 are respectively connected to the two sides of the 20 lap elements 31, and the 20 pre-compressed springs 1 are connected in series to form a row. At the same time, the pre-compressed springs 1 in two adjacent rows, and so on, 10 rows of 20 pre-compressed springs are connected to each other to form an elastic module. Method 2 can also be adopted, where the pre-compressed springs 1 are connected to the lap elements 31 and then the lap elements 31 are spliced together to form an elastic module. The order of splicing the pre-compressed springs 1 and the lap elements 31 in the elastic module is not limited, as long as the purpose of the present invention can be achieved.

The formed elastic module is dense and compression-resistant, and the range of the pre-compressed spring 1 subjected to force can be adjusted according to the posture of the human body. The elastic module of this embodiment is softer and more comfortable when used for furniture such as mattresses, sofas or soft stools.

Example 2

Referring to 15-25, the pre-compression spring 1 of this embodiment is the same as that of Example 1. The main difference between this embodiment and Example 1 is that T-shaped bayonet 22 is provided on opposite sides of the connecting member 2, and the locking portion 22.2 of the T-shaped bayonet 22 is slightly lower than the connecting arm 22.1 in the vertical direction.

The bridge element 32 is provided with retaining members 320 on both sides. Retaining structures 320.3 on the retaining members 320 are independently located within the portion of the retaining notch 320.1 where the retaining portion 22.2 is inserted, i.e., located inside the right limiting portion 320.2. When the T-shaped bayonet 22 is inserted into the retaining notch 320.1 of the retaining member 320, the retaining structures 320.3 vertically limit the retaining portion 22.2 of the T-shaped bayonet 22, thereby retaining the T-shaped bayonet 22.

The locking member 320 also includes a releasing member 320.4 for releasing the T-shaped locking pin from limiting the position. The releasing member 320.4 is connected to the locking structure 320.3 via a cantilevered arm. The releasing member 320.4 pushes the locking structure 320.3 to lock or leave the locking portion 22.2 of the T-shaped locking pin 22 to achieve limiting and releasing the T-shaped locking pin 22.

When the locking cam 320 is in the unlocked position, the locking cam 320 will be locked and the locking cam 320 will be unlocked, so that the locking cam 320 can be unlocked when the locking cam 320 is unlocked.

In this embodiment, the joint piece 3 is integrally formed by the four joint elements 32. A plug-in 321 is provided at the front end of the joint piece 3 formed by the four joint elements 32, and a socket 322 is provided at the rear end of the joint piece 3. The plug-in 321 is inserted into the socket 322 at the rear end of another joint piece 3, so that the length of the joint piece 3 can be adjusted, and the joint piece 3 can be spliced and lengthened according to the size of the elastic module.

More specifically, the thickness of the plug-in 321 is slightly thinner than the thickness of the lap joint 3, and an elastic limiter 321.1 is provided on one side of the plug-in 321. The elastic limiter 321.1 is elastic and can be pressed from a first position protruding from the side of the plug-in 321 to a second position flush with the side of the plug-in 321. The front half of the elastic limiter 321.1 is a downward slope along the direction in which the plug-in 321 is inserted into the socket 322. The thickness of the socket 322 is slightly thicker than the thickness of the connecting piece 3, and a slot 322.1 for inserting the plug-in 321 is provided in the middle of the thickness direction of the socket 322. The thickness of the slot 322.1 is greater than the thickness of the plug-in 321, and less than the overall thickness of the plug-in 321 and the elastic limiting member 321.1. A limiting structure that can limit the elastic limiting member 321.1 is provided in the slot 322. The limiting structure can be a space provided on the inner wall of the slot 322.1 for the elastic limiting member 321.1 to pop out.

In this embodiment, when the joint 3 is extended, the plug-in 321 at the front end of one joint 3 is inserted into the slot 322.1 of the socket 322 at the rear end of the other joint. During insertion, the elastic limiting member 321.1 is pressed by the inner wall of the slot 322.1 and gradually becomes flush with the side of the plug-in 321 so that it can be inserted into the slot 322.1. When the plug-in 321 is inserted into the slot 322.1 until the elastic limiting member 321.1 pops out and is limited by the inner wall of the slot 322.1, the connection between the two joints 3 is realized, so that the joint 3 can be lengthened to form a joint 3 with 8 joint elements 32.

The pre-compression springs 1 are connected to the two side surfaces of the eight bridge elements 32, and the eight pre-compression springs 1 are connected in series to form a row. The pre-compression springs 1 in two adjacent rows are connected to form an elastic module. The rest of the steps are the same as those in Example 1 and will not be repeated here.

Example 3

26-33, the pre-compression spring 1 of this embodiment is the same as that of Example 1. The main difference between this embodiment and Example 1 is that a latch 23 is provided on opposite sides of the connecting member 2, and two cantilever arms 230 are provided on both sides of the latch 23. The cantilever arms 230 are divided into a first portion 230.1 extending upward in the vertical direction and a second portion 230.2 extending outward in the horizontal direction. The first portion 230.1 is provided with a latching structure 230.3 extending outward in the horizontal direction, and the latching structure 230.3 and the second portion 230.1 form a latching groove 230.4.

Slots 330 are provided on both sides of the overlapping element 33 as locking parts. The two sides of the slot 330 are horizontally hollowed out inward so that limiting parts 330.1 are formed on both sides of the upper part of the slot 330. After the pin 23 is inserted into the slot 330, the slot 230.4 and the limiting part 330.1 are matched in the vertical direction to realize the limiting of the pin 23 and the slot 330.

In this embodiment, the latch 23 is also provided with a release member 231 that can release the limit between the latch 23 and the slot 330. The left and right cantilever arms 230 are respectively connected to the two release members 231. The release member 231 pushes and pulls the cantilever arm 230 to drive the locking structure 230.3 to lock or leave the limiting part 330.1 to realize the limiting and release of the latch 23 by the locking member slot 330.

When connecting the pre-compression spring 1, the release members 231 on both sides of the latch 23 of the connector 2 are pressed inward, and then the latch 23 is inserted from above into the slot 330. The release members 231 are released, and the limiting portion 330.1 is then engaged with the locking slot 230.4. After the latch 23 is inserted into the slot 330, it is horizontally restrained by the slot 330. At the same time, the retaining structure 230.3 engages the lower end of the limiting portion 330.1, and the second portion 230.1 engages the upper end of the limiting portion 330.1, thereby vertically restraining the latch 23, thereby completing the connection between the connector 2 and the bridge member 3.

When the pre-compression spring 1 is disassembled, the release members 231 on both sides are pressed inward to drive the locking structure 230.3 to leave the limiting portion 330.1, and then the locking pin 23 is pulled upward from the slot 330 to release the connection between the connecting member 2 and the connecting member 3.

In this embodiment, the five bridge elements 33 are integrally formed into a bridge piece 3. Pre-compression springs 1 are connected to both sides of the five bridge elements 33. The five pre-compression springs 1 are connected in series to form a row, and the pre-compression springs 1 in two adjacent rows are connected. Similarly, ten rows of five pre-compression springs are connected to each other via bridge pieces 3 to form an elastic module. The remaining steps are the same as those in Example 1 and will not be repeated here.

Example 4

34-40 , the pre-compression spring 1 of this embodiment is the same as that of embodiment 1, and two opposite sides of the connecting member 2 are respectively provided with a first connecting structure and a third connecting structure, and the first connecting structure is different from the third connecting structure.

Specifically, the two opposite side surfaces of the connecting member 2 extend outward to form extension portions 24 and 25, respectively, wherein one side extension portion 24 is provided with a rotatable protrusion 24.1 that can rotate around the extension portion 24 as a first connection structure, and the other side extension portion 25 is provided with a recessed hole 25.1 for the rotatable protrusion 24.1 to extend into as a third connection structure.

In this embodiment, the connecting member 3 is formed by integrally forming 16 connecting elements 34. The connecting elements 34 are also provided with connecting holes 34.1 for the rotatable protrusions 24.1 to extend therein as a second connecting structure.

When connecting the pre-compression spring 1, the rotatable protrusion 24.1 on the connector 2 is inserted into the connecting hole 34.1 on the bridge element 34. At this time, the rotatable protrusion 24.1 and the second connecting hole 34.1 are horizontally limited. The rotatable protrusion 24.1 is rotated until it is offset from the connecting hole 34.1. At this time, the rotatable protrusion 24.1 and the connecting hole 34.1 are vertically limited to connect the bridge element 23 to the connector 2. The pre-compression spring 1 is connected to the 16 bridge elements of the bridge element 3 respectively, thereby connecting the pre-compression springs 1 in series into a row.

When connecting two adjacent rows of pre-compression springs 1, the rotatable protrusion 24.1 of the rear row pre-compression spring 1 is inserted into the recessed hole 25.1 of the pre-compression springs 1 in the front row that have been connected in series and the connection holes 34.1 of each bridging element 34 of the bridging member 3, and then the rotatable protrusion 24.1 is rotated to be offset from the recessed hole 25.1 and the connection hole 34.1. At this time, the rotatable protrusion 24.1 is limitedly engaged with the recessed hole 25.1 and the connection hole 34.1 to achieve the connection of the front and rear rows of pre-compression springs 1. As a simple alternative to this embodiment, the front and rear rows of pre-compression springs 1 connected in series via the bridging member 3 can also be connected by directly inserting the rotatable protrusion 24.1 of the rear row pre-compression spring 1 into the recessed hole 25.1 of the front row pre-compression spring 1, and then rotating the rotatable protrusion 24.1 to be offset from the recessed hole 25.1 for limiting.

When the pre-compression spring 1 is to be disassembled, it is only necessary to rotate the rotatable protrusion 24.1 until it overlaps with the concave hole 25.1 and the connecting hole 34.1, and then remove it from the bottom.

In this embodiment, the 16 bridge elements 34 are integrally formed into a bridge member 3. Precompressed springs 1 are connected to each of the 16 bridge elements 34, thereby forming a series of rows. The rotatable protrusion 24.1 is then inserted into the recessed hole 25.1 and the connecting hole 34.1 on the bridge member according to the aforementioned connection method. The rotatable protrusion 24.1 is rotated to offset the recessed hole 25.1 and the connecting hole 34.1, thereby connecting two adjacent rows of precompressed springs 1. Similarly, seven rows of 16 precompressed springs are interconnected via the bridge member 3 to form an elastic module. The remaining steps are the same as in Example 1 and will not be repeated here.

The number of overlapping elements on the overlapping member 3, the number of pre-compressed springs 1 connected in series and the number of rows of pre-compressed springs, the connection sequence of the overlapping member 3 and the pre-compressed springs 1, etc. can be adjusted according to the size of the elastic module or the needs of the user, and are not limited to those mentioned in Example 1, Example 2, Example 3, and Example 4.
