[0004] Spring beds, sofa beds, and other furniture are essential components of our lives. Most existing beds and sofa beds are equipped with spring pads. These pads have a certain degree of elasticity, providing support and a degree of comfort compared to hard pads.

[0005] The softness or hardness of the elastic cushion directly affects the comfort of beds and sofa beds, and thus directly affects the quality of people's rest. At present, the elasticity of common elastic cushions is fixed, and users can only choose between two elasticities when the elastic cushion is in the forward and reverse states, which results in a relatively simple functional selection. In addition, the elasticity of one side of the elastic cushion is fixed. For example, people with poor lumbar spine may need the elastic cushion to be softer or harder in the lumbar area. This demand cannot be met by the current elastic cushions with consistent elasticity on one side. As a result, users will experience soreness when lying on the elastic cushion due to the local area being too hard or too soft. Summary of the Invention

[0088] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0089] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0090] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0091] 1 to 62 , the present embodiment provides an elastic pad that can be customized to be soft or hard. The elastic pad 5 is composed of several groups of spring modules 4 with different hardness, and the spring modules 4 are composed of several spring members 1 spliced ​​together. The elastic member is a pre-compressed spring, and the hardness is the predetermined initial compression force of the spring in the spring member 1; the several groups of spring modules 4 include at least two groups of spring modules 4 with different elastic hardness; the spring module 4 group has a spring member 1 with at least one hardness; a connecting structure 2 is provided on the spring member 1, and a plurality of spring members 1 are connected by the connecting structure 2 or by the connecting structure 2 through a third connecting member 3; the spring module 4 is arranged in an staggered or array manner by a plurality of spring members 1 through the connecting structure 2; the spring modules 4 with different hardness in the elastic pad 5 are constructed to be assembled in any area in the elastic pad 5 by the connecting structure 2 or the third connecting member 3; the hardness of the spring member 1 arranged in the edge area of ​​the elastic pad 5 is greater than the hardness of the spring member 1 in other areas of the elastic pad 5 except the edge area.

[0092] In this embodiment, the hardness adjustment of the spring members 1 of different hardness involved can select spring members 1 of different hardness, wherein a single spring member 1 is constructed so that the upper and lower support ends have equal or unequal hardness, or at least one of the support ends of a single spring member 1 is constructed so that the hardness is adjustable, that is, an adjusting member is provided at the support end to act on the spring member 1 to adjust the predetermined initial compression force of the spring, thereby changing the hardness of the spring member 1.

[0093] The spring component 1 described herein is a pre-compressed spring, and its elastic hardness is a predetermined initial compression force of the spring 11 in the spring component 1. Specifically, the spring component 1 includes a cloth cover 12, or a webbing, an upper cover and a base. The spring 11 is arranged in a cavity surrounded by the upper cover, the base and the cloth cover. By adjusting the length of the cloth cover 12, the initial pressure of the spring 11 in the spring component 1 is obtained in advance, so that the spring component 1 has the required elastic hardness. Elastic modules with different elastic hardness are arranged at different parts of the elastic pad; the elastic modules in the elastic pad can realize compression and release movements that are truly independent of each other, so that the elastic pad has better comfort.

[0094] In another embodiment, a single spring member 1 includes a support sleeve and a spring mounted in the support sleeve. The support sleeve acts on the spring under a predetermined initial compression force. A spring pre-tightening device is provided at the support end of the support sleeve. The spring pre-tightening device is located at the elastic compression end of the spring, i.e., one end of the spring. The spring pre-tightening device is used to adjust the initial compression force of the spring. The support sleeve is used to make the spring have a predetermined initial compression force. The spring pre-tightening device can further press down the spring under the initial compression force to further compress the spring, thereby effectively increasing the hardness of the spring. The spring pre-tightening device can be a spiral progressive structure. By gradually pressing down the spring or releasing the spring in the opposite direction, the spring is adjusted within the initial compression force. A section of the spring is pre-tightened from one end of the spring. In this way, different sections of the same spring have different hardnesses. The lower section of the spring has a greater hardness, while the upper section of the spring is softer.

[0095] The first embodiment, as shown in Figures 1 to 7, provides a spring module 4 composed of three spring members 1 of different hardness.

[0096] As shown in the figure, since there are three spring members 1 with different hardness, this embodiment takes three spring structures of spring hardness A, spring hardness B and spring hardness C as examples, where the hardness is as follows: spring hardness A is greater than spring hardness B, which is greater than spring hardness C. Of course, in the selection of spring hardness, for the spring member 1 used for laying on the edge of the elastic pad 5, the spring hardness A with the largest hardness is adopted, while the area in the middle of the elastic pad 5 for lying down adopts the spring hardness B and spring hardness C with smaller hardness. The hardness difference between the spring hardness B and the spring hardness C is not large, which retains a certain hardness while meeting the softness to meet the user's demand for different hardness adjustments.

[0097] In this embodiment, the spring module 4 is used as an adjustment module, and the spring module 4 is spliced ​​according to the spring parts 1 of different hardness to obtain spring modules 4 of different hardness. Then, the spring module is used to realize the splicing adjustment of the softness and hardness of the spring part 1 in any area. According to the user's requirements, the hardness of the splicing in different positions or different areas changes. It is a customized splicing spring module that truly adapts to different softness and hardness requirements.

[0098] For example, in Figure 1, on the elastic pad 5 formed, most of the head is equipped with a pillow, and there are not many soft or hard requirements for the setting of the spring member 1 at the head. However, in the waist area, people with bad lumbar spine prefer a more obvious hard touch. Therefore, for the elastic pad 5, a spring member 1 with a spring hardness of B is used as a pad in the area corresponding to the waist of the human body. At the same time, in order to match the hardness of the waist and abdomen, and to avoid the local hardness of the waist when lying down, which leads to a greater pressure on the lumbar spine, spring members 1 of the same hardness are set on the edges of the elastic pad 5 corresponding to the legs and feet, and spring members 1 with a spring hardness of C are used as pads in other positions. This provides better support for the waist and legs of the human body when lying down, provides better lying comfort, and improves sleep quality.

[0099] At the same time, in this embodiment, a spring hardness A is set on the edge side of the elastic pad 5 as the edge paving to provide a little hardness requirement on the edge of the elastic pad 5 to avoid the edge collapse caused by long-term sitting.

[0100] Of course, the splicing method is not limited to the one provided in the present embodiment. You may choose to provide an elastic pad 5 with a spring hardness C as the main support in the middle as shown in FIG2 ; or provide an elastic pad 5 with a spring hardness B as the middle support and a hardness C at both ends as shown in FIG3 ; or provide an elastic pad 5 with spring parts of spring hardness B and spring hardness C alternately partitioned as shown in FIG4 ; or provide an elastic pad 5 with spring parts of spring hardness B and spring hardness C alternately partitioned as shown in FIG5 , and with different partitions for two persons at different heights (and different partitions for two persons are distinguished).

[0101] In this embodiment, a structure for using an elastic pad 5 is also provided, as shown in Figures 6-7. The structure comprises a cushioning layer 6 laid on the upper layer of the elastic pad 5, wherein the cushioning layer 6 has short edges or short braces on all four sides, and a connecting structure 2 consistent with the spring module 4 is provided on the short edges or short braces to form a detachable connection with the connecting structure 2 on the outer periphery of the spring module 4.

[0102] In order to achieve rapid assembly of the elastic module and the cushion layer 6 and to make the whole after nesting have better stability, based on the first embodiment, the structure of the specific connection structure 2 between the specific spring members 1 is provided below, with reference to Figures 8-62.

[0103] The second embodiment is shown in Figures 8-11.

The connecting structure 2 is staggered and arranged at equal intervals along the circumference, forming releasable snap-on connections with snap locations 21 and snap points 22. The snap locations 21 have protrusions 211, while the snap points 22 have grooves 221. The protrusions 211 are elastic, and the snap points 22 are provided with release members 23 that counteract the elasticity of the protrusions 211. The snap points 22 are located on two opposing sides of the connecting structure 2, while the snap locations 21 are located on two other opposing sides of the connecting structure 2.

Each cavity 24 comprises a male and female buckle that can releasably engage with each other. The buckle position 21 has a protrusion 211, and the buckle point 22 has a groove 221. The protrusion 211 is elastic, and the buckle position 21 is provided with a release member 23 that releases the elasticity of the protrusion 211.

[0109] Specifically, a locking structure is provided on the protrusion 211 to limit the engagement with the groove 221. The locking structure is elastic. The release member 23 is provided on one side of the protrusion 211 and is linked to the protrusion 211.

[0112] A plurality of connecting structures 2 are provided around the periphery of the spring member 1. The connecting structures 2 are used to form a connection via a third connecting member 3. The connecting structures 2 are connected to the spring member 1 and are provided with a plurality of buckling positions 21. The third connecting member 3 is provided with buckling points 22. The buckling points 22 of the third connecting member 3 can simultaneously form a releasable buckle with one of the buckling positions 21 of the four connecting structures 2 of the spring member 1.

[0113] The specific structure of the connecting structure 2 and the third connecting member 3 is that the buckle position 21 has a protrusion 211, the buckle point 22 has a groove 221, and the buckle point 22 is provided with a rotating member 25 on the outer periphery of the groove 221. When the buckle position 21 is placed in the buckle point 22, the rotating member 25 rotates to lock the buckle position 21.

[0114] The buckle position 21 includes a protrusion 211 and an annular groove 213 extending from the protrusion 211 to the main body of the buckle point 22, and the buckle point 22 includes a cavity for accommodating the protrusion 211, a notch 222 for accommodating the annular groove 213, and an opening 223 that passes through the cavity and the notch 222; the protrusion 211 enters the cavity through the opening 223; a rotating member 25 is arranged on the outer side of the cavity, and the rotating member 25 is provided with an annular opening 251 adapted to the opening 223; the rotating member 25 is rotated so that the opening 223 and the annular opening 251 are relative or staggered, which is used to unlock or lock the protrusion 211.

[0115] The fifth embodiment is shown in Figures 21-23.

[0116] A plurality of plug-in waist rings are provided around the periphery of the spring element 1 as a connecting structure 2.

The buckle positions 21 have protrusions 211, and the buckle points 22 include cavities for accommodating the protrusions 211 and openings 223. A downwardly pressing sliding member 26 is provided on the outer periphery of the cavity of the buckle point 22. When the buckle position 21 is placed within the buckle point 22, the sliding member 26 slides and locks the buckle position 21.

[0117] The buckle position 21 includes a protrusion 211 and an annular groove 213 extending from the protrusion 211 to the buckle point 22 body, and the protrusion 211 enters the cavity through the opening 223; a downward-pressing sliding member 26 is slidably assembled on the outside of the cavity, and the sliding member 26 includes an insertion port 261 adapted to the size of the opening 223 and a locking port 262 adapted to the diameter of the annular groove 213; the insertion port 261 is communicated with the locking port 262; the sliding member 26 slides up and down so that the insertion port 261 or the locking port 262 is opposite to the opening 223, which is used to unlock or lock the protrusion 211.

[0118] The sixth embodiment is shown in Figures 24-28.

[0119] A plurality of waist rings with plug-in functions are arranged around the circumference of one of the spring members 1 as connecting structures 2. The connecting structures 2 arranged on the plurality of spring members 1 are divided into two structures. One of the connecting structures 2 has a plurality of buckle points 22 distributed along the circumference, and the other connecting structure 2 has a plurality of buckle positions 21 distributed along the circumference. The buckle position 21 has a protrusion 211, and the buckle point 22 has a locking hole 224. The buckle position 21 is provided with a rotating member 215 at the lower end of the protrusion 211. When the buckle position 21 is placed in the locking hole 224, the portion where the rotating member 215 is provided passes through the locking hole 224, and the buckle position 21 is locked in the locking hole 224 by the rotation of the rotating member 215.

[0120] The buckle position 21 includes a locking member 214 and a rotating member 215 (rotating member) that can rotate relative to the locking member 214; the buckle point 22 includes a locking hole 224 that can pass through the locking member 214 and the rotating member 215. The buckle position 21 arranges the rotating member 215 and the locking member 214 in sequence along the insertion direction. The rotating member 215 can rotate relative to the locking member 214 and be aligned or misaligned with the locking member 214. When the rotating member 215 is aligned with the locking member 214, it can be inserted into the locking hole 224 in sequence. When the rotating member 215 continues to be inserted along the insertion direction until it passes through the locking hole 224 and is located at the lower end of the locking hole 224, the rotating member 215 is misaligned with the locking hole 224 by rotation, which is used to lock the locking member 214 in the locking hole 224.

[0121] The seventh embodiment is shown in Figures 29-32.

[0122] Multiple plug-in waist rings are arranged around the periphery of the spring element 1 as a connecting structure 2. The connecting structure 2 is staggered and arranged at equal intervals along the circumference, forming releasable snap-on connections with snap locations 21 and snap points 22. The snap locations 21 have protrusions 211, while the snap points 22 have grooves 221. The protrusions 211 are elastic, and the snap points 22 are provided with release members 23 that counteract the elasticity of the protrusions 211. The snap points 22 are located on two opposing sides of the connecting structure 2, while the snap locations 21 are located on two other opposing sides of the connecting structure 2.

[0123] A rectangular connector is provided on the buckle position 21, and two protrusions 211 are provided on both side arms of the rectangular connector. A slide groove 225 is provided on the corresponding buckle point 22 on the end surface of the buckle point 22, and two grooves 221 are provided on the two opposite sliding side walls inside the slide groove 225. When the rectangular connector slides inward along the sliding wall of the slide groove 225, it slides until the protrusion 211 is aligned with the groove 221. At this time, the protrusion 211 pops out and is stuck on the groove 221, forming a sliding limit for the rectangular connector, thereby realizing the buckling connection and fixation of the buckle position 21 and the buckle point 22.

[0124] The buckle point 22 is provided with a button 231 as a release member 23 at the groove 221. Pressing the button 231 inward causes the protrusion 211 to retract and release the buckle from the groove 221. When unlocking is required, only the buttons 231 on both sides need to be pressed to retract the protrusion 211 to release the buckle.

[0125] The eighth embodiment is shown in Figures 33-35.

[0126] The second embodiment also includes equidistantly spaced snap-in locations 21 and snap-in points 22 arranged along the circumference of the connecting structure 2 to form a releasable snap connection. The snap-in locations 21 have protrusions 211, and the snap-in points 22 have grooves 221. The protrusions 211 are elastic, and the snap-in points 22 are provided with release members 23 to counteract the elasticity of the protrusions 211.

[0127] The protrusion 211 is provided with a locking structure (i.e., a protrusion 212) which is limitedly engaged with the groove 221. The locking structure is elastic, and the release member 23 is provided at a position corresponding to the wall of the groove 221 and the locking structure; pressing the release member 23 drives the locking structure to release the limited engagement with the groove 221 to realize the disassembly of the spring member 1.

[0128] As an optimized structure, the button 231 is used as the release member 23, so that the appearance of the connection structure 2 is more beautiful and natural.

[0129] The ninth embodiment is shown in Figures 36-44.

[0130] The connection structure 2 provided in this embodiment is primarily connected via a third connecting member 3. Multiple connection structures 2 are arranged around a spring member 1, and the connection structures 2 are used to form a connection via the third connecting member 3. The connection structure 2 is a connecting member assembled around the spring member 1. The connection structure 2 is configured with a plurality of snap locations 21. The third connecting member 3 is configured with snap points 22, which are provided on two opposing sides of the connection structure 2. The snap locations 21 are provided on two opposing sides of the third connecting member 3, with only one snap location 21 provided on one side of the third connecting member 3.

[0131] The buckle position 21 has a protrusion 211 , and the buckle point 22 has a groove 221 . A side wall of the groove 221 is elastic. A release member 23 is provided on the buckle point 22 to push the elastic side wall of the groove 221 .

[0132] Specifically, a locking structure (i.e., a protrusion 212) is provided on the protrusion 211 to limit the engagement with the groove 221. A side wall of the groove 221 has a limiting structure 31 that limits the engagement with the locking structure. The limiting structure 31 is elastic. The release member 23 is provided on one side of the limiting structure 31 and is linked to the limiting structure 31. Pressing the release member 23 drives the limiting structure 31 to release the limiting engagement with the groove 221 to realize the disassembly of the spring member 1.

[0133] At the same time, both ends of the third connecting member 3 are provided with mutually engageable snap-fitting members, which include an engaging position 32 and a joining position 33. The engaging position 32 of one third connecting member 3 and the joining position 33 of another third connecting member 3 form a releasable connection, thereby forming a row of third connecting members 3 for connecting the spring member 1.

[0134] In this embodiment, there are two ways to connect the third connecting member 3 to the spring member 1. One is to first connect a plurality of third connecting members 3 end-to-end to form a long row of third connecting members 3, and then connect the buckle points 22 of the third connecting members 3 in the row to the buckle positions 21 on the spring member 1 in sequence to form a spring module 4. The spring module 4 is arranged in a row, and then the buckle points 22 and buckle positions 21 between rows are connected to form an elastic pad 5 (as shown in Figure 42). The other is to first connect the buckle points 22 on both sides of a single third connecting member 3 to the buckle positions 21 on the spring member 1 in sequence, and then connect a plurality of spring members 1 to the third connecting member 3 via the connecting structure 2 to form a spring module 4. The spring module 4 is arranged in a row, and then the rows are connected end-to-end using the clips provided on the third connecting member 3 to form an elastic pad 5 (as shown in Figures 43-44).

[0135] The tenth embodiment is shown in Figures 45-50.

[0136] Based on the ninth embodiment, a third connecting member 3 different from the ninth embodiment is provided. The design of the third connecting member 3 is different from that of the ninth embodiment in that four buckle positions 21 are set on a single side of the third connecting member 3, and the setting is not limited to the four buckle positions 21.

[0137] The ninth embodiment optimizes the arrangement of the third connecting member 3 , simplifies the number of parts of the third connecting member 3 , and allows for faster connection between the third connecting members 3 and between the third connecting member 3 and the spring member 1 .

[0138] The eleventh embodiment is shown in Figures 51-57.

[0139] The connection structure 2 provided in this embodiment is primarily connected via a third connecting member 3. Multiple connection structures 2 are arranged around the periphery of a spring member 1. These connection structures 2 are used to form a connection via the third connecting member 3. The connection structure 2 is assembled around the spring member 1. The connection structure 2 is constructed with two opposing side surfaces, one of which is provided with a buckle position 21, and the other with a buckle point 22. The third connecting member 3 is also configured with buckle points 22, and the buckle points 22 are provided along its length.

[0140] The buckle position 21 includes a locking member 214 and a rotating member 215 that can rotate relative to the locking member 214; the buckle point 22 includes a locking hole 224 that can pass through the locking member 214 and the rotating member 215, and the locking member 214 can be inserted into two locking holes 224 at the same time in terms of height setting. The buckle position 21 arranges the rotating member 215 and the locking member 214 in sequence along the insertion direction. The rotating member 215 can rotate relative to the locking member 214 and be aligned or misaligned with the locking member 214. When the rotating member 215 is aligned with the locking member 214, it can be inserted into the locking hole 224 in sequence. When the rotating member 215 continues to be inserted along the insertion direction until it passes through the locking hole 224 and is located at the lower end of the locking hole 224, the rotating member 215 is misaligned with the locking hole 224 by rotation, which is used to lock the locking member 214 in the locking hole 224.

[0141] At the same time, a buckle position 21 with the same structure as the connection structure 2 is set at one end of the two ends of the third connecting member 3, and is connected to the buckle point 22 at the other end. A plurality of third connecting members 3 can be connected to the buckle position 21 by the buckle point 22 to form a row of third connecting members 3 for connecting the spring member 1.

[0142] The connection between the third connecting member 3 and the spring member 1 is that in the connection of two rows of spring members 1, the buckle points 22 on one row of spring members 1 and the buckle points 22 of the third connecting member 3 are simultaneously connected to the buckle positions 21 on the other row of spring members 1, as shown in Figure 57, and the spring members 1 in the elastic pad 5 formed therein are arranged in an array.

[0143] Of course, the third connecting member 3 in this embodiment can also be applied to a structure similar to the sixth embodiment in which only the buckle positions 21 are provided on the connecting structure 2 of the spring members 1. Buckle positions 21 are provided on two opposite sides of the spring members 1. When connecting the two rows of spring members 1, the buckle positions 21 and the buckle points 22 of the third connecting member 3 form an interlaced connection. The spring members 1 in the elastic pad 5 formed therein are arranged in an interlaced manner.

[0144] The twelfth embodiment is shown in Figures 58-62.

[0145] The connection structure 2 provided in this embodiment is mainly connected by a third connecting member 3. A plurality of connection structures 2 are arranged around the circumference of a spring member 1. The connection structure 2 is used to form a connection through the third connecting member 3. The connection structure 2 is a connection member assembled around the spring member 1. Buckles 21 are provided on two opposite sides of the connection structure 2, and buckle points 22 are provided on two opposite sides of the third connecting member 3. The third connecting member 3 is provided with a plurality of buckle points 22 along its length. The buckle position 21 has a protrusion 211, and the buckle point 22 has a groove 221. The protrusion 211 is elastic, and a release member 23 is provided on the buckle position 21 to presume the elasticity of the protrusion 211.

[0146] Specifically, a locking structure is provided on the protrusion 211 to limit the engagement with the groove 221. The locking structure is elastic. The release member 23 is provided on one side of the protrusion 211 and is linked to the protrusion 211. Pressing the release member 23 drives the locking structure to release the limiting engagement with the groove 221 to realize the disassembly of the spring member 1.

[0147] The locking structure is a protrusion 212 located above the protrusion 211, and the release member 23 is provided on the side of the protrusion 211 where the protrusion 212 is provided. The upper wall of the groove 221 is provided with a space for locking the protrusion 212, thereby realizing the limiting cooperation between the locking structure and the groove 221.

[0148] At the same time, both ends of the third connecting member 3 are provided with mutually engageable snap-fitting members, which include an engaging position 32 and a joining position 33. The engaging position 32 of one third connecting member 3 and the joining position 33 of another third connecting member 3 form a releasable connection, thereby forming a row of third connecting members 3 for connecting the spring member 1.

[0149] In this embodiment, the third connecting member 3 includes a structure at one end thereof for forming a connection with the cushioning layer 6. The structure for forming a connection with the cushioning layer 6 can be consistent with the structure for forming a connection with the spring member 1. The structure for forming a connection between the third connecting member 3 and the cushioning layer 6 is also involved in the other embodiments described above.
