BACKGROUND OF THE DISCLOSURE

Bed mattresses are essential furniture in beddings for human use in modern life. Elastic bed mattresses with a middle part having elastic components are becoming increasingly popular for relaxation during sleep with increasing pressure in human lives. In order to withstand greater pressure, springs of the existing elastic mattresses, such as bed mattresses with elastic components, are often formed as whole structures and are not independent from each other. Even with respect to independent pocket springs, various spring ends of the pocket springs are often connected together through a connecting base, so that stress applied to a local portion will drive springs around the local portion to be subjected to the stress, thereby preventing the elastic mattresses comprising the pocket springs from changing a stress scope applied to the springs to conform to a curve of a human body by following a posture of the human body.

Therefore, the existing elastic mattresses cannot enable the elastic mattresses to conform to the curve of the human body to be more comfortable and softer by adjusting the stress according to a sleeping posture of a person.

Embodiment 1

Referring to FIGS. 1-14, this embodiment provides an elastic module, and the elastic module comprises a plurality of pre-compressed springs 1. The plurality of pre-compressed springs 1 are waist-shrinking springs with two ends larger than middle parts. Outer sides of springs are wrapped with fabric sleeves (i.e., the springs in the fabric sleeves are pre-compressed by the fabric sleeves to form the plurality of pre-compressed springs 1). One of connecting members 2 is sleeved on an outer side of a corresponding one of the fabric sleeves wrapped on the middle parts of the plurality of pre-compressed springs 1. The elastic module further comprises one or more lapping members 3. The one or more lapping members 3 are formed by a front-and-rear spliced connection of a plurality of lapping units 31. The plurality of pre-compressed springs 1 contact or approach. The connecting members 2 on the plurality of pre-compressed springs 1 and the plurality of lapping units 31 of the one or more lapping members 3 are connected each other. Each of the plurality of lapping units 31 on the one or more lapping members 3 is connected to a corresponding one of the plurality of pre-compressed springs 1. The one or more lapping members 3 connect the plurality of pre-compressed springs 1 in series to form rows and are connected to two adjacent ones of the rows of the plurality of pre-compressed springs 1.

Specifically, in this embodiment, two opposite side surfaces of each of the connecting members 2 are respectively disposed with one of buckling pins 21 acting as a first connecting structure. The buckling pins 21 comprise connecting arms 211 and position-buckled portions 212. The connecting arms 211 are fixedly connected to the two opposite side surfaces of a corresponding one of the connecting members 2 to enable the buckling pins 21 to be fixedly connected to the corresponding one of the connecting members 2. Widths of the connecting arms 211 are smaller than widths of the position-buckled portions 212, so that the buckling pins 21 define T-shaped buckling pins 21.

The plurality of lapping units 31 define elongated shapes, and position-buckled members 310 configured to limit positions of the T-shaped buckling pins 21 and acting as a second connecting structure are respectively disposed on two side surfaces a corresponding one of the plurality of lapping units 31 with the elongated shapes. The position-buckled members 310 are fixedly connected to the two side surfaces of the corresponding one of the plurality of lapping units 31. Each of the position-buckled members 310 comprises a position-buckled notch 3101 into which a corresponding one of the T-shaped buckling pins 21 is inserted, position-limited portions 3102 configured to limit a position of a corresponding one of the position-buckled portions 212 in a horizontal direction and formed by extending inward in opposite directions from two sides of a side surface of each of the position-buckled members 310 in a direction facing away from the corresponding one of the plurality of lapping units 31, and a position-buckled structure 3103 disposed on one of the position-limited portions 3102 on a right side. The position-buckled structure 3103 is configured to limit a position of a corresponding one of the T-shaped buckling pins 21 disposed in the position-buckled notch 3101 in a vertical direction. As a simple alternative to this embodiment, the position-buckled structure 3103 can also be disposed on one of the position-limited portions 3102 on a left side, or the position-buckled structure 3103 can be disposed on each of the position-limited portions 3102 on two sides.

The position-buckled structure 3103 has elasticity. Each of the position-buckled members 310 further comprises a releasing member 3104 configured to release from limiting a position of a corresponding one of the T-shaped buckling pins 21. The releasing member 3104 is connected to the position-buckled structure 3103 through a cantilevered arm. The releasing member 3104 pushes and pulls the position-limited portions 3102 to drive the position-buckled structure 3103 to be buckled to or be separated from a corresponding one of the connecting arms 211 of the T-shaped buckling pins 21, thus limiting the position of the corresponding one of the T-shaped buckling pins 21 and releasing the corresponding one of the T-shaped buckling pins 21.

When the plurality of pre-compressed springs 1 are connected, the releasing member 3104 is pressed to pull the one of the position-limited portions 3102 on the right side to enable the position-limited portions 3102 on the two sides to form a space configured to receive the corresponding one of the connecting arms 211 of the T-shaped buckling pins 21. At this time, each of the T-shaped buckling pins 21 on each of the connecting members 2 of the plurality of pre-compressed springs 1 and acting as the first connecting structure is inserted into the position-buckled notch 3101 on the corresponding one of the position-buckled members 310 of the plurality of lapping units 31 and acting as the second connecting structure from an upper side. After insertion, a position of each of the position-buckled portions 212 is limited by the position-limited portions 3102 in the horizontal direction, and each of the connecting arms 211 is disposed between the position-limited portions 3102 on the two sides. The releasing member 3104 is released to allow the position-buckled structure 3103 to limit a position of a corresponding one of the connecting arms 211 in the vertical direction, so that each of the T-shaped buckling pins 21 and a corresponding one of the position-buckled members 310 form a position-limited cooperation to achieve a connection between the corresponding one of the plurality of lapping units 31 and the corresponding one of the connecting members 2.

Similarly, each of the T-shaped buckling pins 21 of each of the connecting members of the plurality of pre-compressed springs 1 is inserted into a corresponding one of the position-buckled members 310 on the two sides of a corresponding one of the plurality of lapping units 31 of the one or more lapping members 3. The one or more lapping members 3 comprise the plurality of lapping units 31. The plurality of lapping units 31 enable the plurality of pre-compressed springs 1 to be connected to the one or more lapping members 3 synchronously to connect the plurality of pre-compressed springs 1 in series to form the rows. At the same time, as the position-buckled members 310 are disposed on the two sides of the corresponding one of the plurality of lapping units 31, each of the position-buckled members 310 on the two sides of the corresponding one of the plurality of lapping units 31 is connected to a corresponding one of the T-shaped buckling pins 21 of a corresponding one of the connecting members of the plurality of pre-compressed springs 1 to connect the plurality of pre-compressed springs 1 in the two adjacent ones of the rows together.

In this embodiment, the one or more lapping members 3 are formed by the front-and-rear spliced connection of the plurality of lapping units 31. A front end of each of the plurality of lapping units 31 comprises an insertion member 311, and a rear end of each of the plurality of lapping units 31 comprises an insertion socket 312. The insertion member 311 of the front end of a rear one of the plurality of lapping units 31 is inserted into the insertion socket 312 of the rear end of a front one of the plurality of lapping units 31 to realize a spliced connection of two adjacent lapping units 31 of the plurality of lapping units 31.

More specifically, a thickness of the insertion member 311 of the front end of each of the plurality of lapping units 31 is slightly thinner than a thickness of each of the plurality of lapping units 31. An elastic position-limited member 3111 is disposed on a side surface of the insertion member 311, and the elastic position-limited member 3111 has elasticity and can be pressed from a first position protruding from the side surface of the insertion member 311 to a second position aligned with the side surface of the insertion member 311. A front half of the elastic position-limited member 3111 defines a downwardly-inclined plane along a direction in which the insertion member 311 is inserted into the insertion socket 312. A thickness of the insertion socket 312 of the rear end of each of the plurality of lapping units 31 is slightly thicker than the thickness of each of the plurality of lapping units 31. A middle of the insertion socket 312 in a thickness direction comprises an insertion groove 3121 into which the insertion member 311 is inserted. A thickness of the insertion groove 3121 is greater than the thickness of the insertion member 311 and smaller than a total thickness of the insertion member 311 and the elastic position-limited member 3111. An inner side of the insertion groove 3121 comprises a position-limited structure configured to limit a position of the elastic position-limited member 3111, and the position-limited structure can be a space on an inner wall of the insertion groove 3121 configured for popping out the elastic position-limited member 3111.

When the one or more lapping members 3 are formed by the front-and-rear spliced connection of the plurality of lapping units 31, the insertion member 311 of the front end of the rear one of the plurality of lapping units 31 is inserted into the insertion groove 3121 of the insertion socket 312 of the rear end of the front one of the plurality of lapping units 31. During an inserting process, the elastic position-limited member 3111 is pressed by the inner wall of the insertion groove 3121 to be gradually aligned with the side surface of the insertion member 311 so as to be inserted into the insertion groove 3121. When the insertion member 311 is inserted into the insertion groove 3121 until the elastic position-limited member 3111 pops out and is limited by the inner wall of the insertion groove 3121, a connection between the front one and the rear one of the plurality of lapping units 31 is achieved. In order to adapt to various application scenarios, such as hospital beds, where a bed head needs to be raised, as a simple alternative to this embodiment, the insertion member 311 can rotate around the insertion socket 312, so that the elastic module can be folded and raised.

A number of the plurality of lapping units 31 of the one or more lapping members 3 can be adjusted according to a size of the elastic module. In this embodiment, the plurality of lapping units 31 comprise twenty lapping units 31 having the front-and-rear spliced connection according to the aforementioned method. The plurality of pre-compressed springs 1 are then respectively connected to two side surfaces of the twenty lapping units 31 to connect twenty pre-compressed springs 1 of the plurality of pre-compressed springs 1 together in series to form a row and connected to the plurality of pre-compressed springs 1 in two adjacent rows synchronously. Similarly, ten rows of the twenty of the plurality of pre-compressed springs 1 are connected together to form the elastic module. The plurality of pre-compressed springs 1 are connected to the plurality of lapping units 31, and the plurality of lapping units 31 are then spliced together to form the elastic module using the second method (shown in FIG. 13). A spliced sequence of the plurality of pre-compressed springs 1 and the plurality of lapping units 31 to form the elastic module is not limited to what is described herein, as long as a purpose of the present disclosure can be achieved.

The formed elastic module is dense, compact, and resistant to stress, and at the same time, a stress scope applied to the plurality of pre-compressed springs 1 can be adjusted according to a posture of a human body. The elastic module of this embodiment is softer and more comfortable when being used for bed mattresses, sofas, upholstered stools, or other furniture.

Embodiment 2

Referring to FIGS. 15-25, the plurality of pre-compressed springs 1 of this embodiment are the same as that of Embodiment 1. This embodiment mainly differs from Embodiment 1 in that two opposite sides of each of the connecting members 2 comprise T-shaped buckling pins 22 (i.e., buckling pins 22). Position-buckled portions 222 of the T-shaped buckling pins 22 are slightly lower than connecting arms 221 in the vertical direction.

Two sides of each of a plurality of lapping units 32 each comprises a position-buckled member 320. A position-buckled structure 3203 of the position-buckled member 320 is independently disposed in a part of a position-buckled notch 3201 into which a corresponding one of the position-buckled portions 222 is inserted. That is, the position-buckled structure 3203 is disposed on an inner side of a right one of position-limited portions 3202. When each of the T-shaped buckling pins 22 is inserted into the position-buckled notch 3201 of the position-buckled member 320, the position-buckled structure 3203 limits a position of the corresponding one of the position-buckled portions 222 of the T-shaped buckling pins 22 in the vertical direction to limit positions of the T-shaped buckling pins 22.

The position-buckled member 320 further comprise a releasing member 3204 configured to release from limiting a position a corresponding one of the T-shaped buckling pins 22. The releasing member 3204 is connected to the position-buckled structure 3203 through a cantilevered arm. The releasing member 3204 pushes the position-buckled structure 3203 to be buckled to or be separated from the corresponding one of the position-buckled portions 222 of the T-shaped buckling pins 22 to limit the position of the T-shaped buckling pins 22 and release the T-shaped buckling pins 22.

When the plurality of pre-compressed springs 1 are connected, the releasing member 3204 is pressed to pull the position-buckled structure 3203 apart to enable the position-buckled notch 3201 on the inner sides of the position-limited portions 3202 to form a space into which the corresponding one of the position-buckled portions 222 of the T-shaped buckling pins 22 is inserted. At this time, each of the T-shaped buckling pins 22 on a corresponding one of the connecting members 2 of a corresponding one of the plurality of pre-compressed springs 1 acting as a first connecting structure is inserted into the position-buckled notch 3201 on the position-buckled member 320 of the plurality of lapping units 32 acting as a second connecting structure from an upper side. After insertion, a position of the corresponding one of the position-buckled portions 222 is limited by the position-limited portions 3202 in a horizontal direction, and each of the connecting arms 221 is disposed between the position-limited portions 3202 on the two sides. The releasing member 3204 is released to enable the position-buckled structure 3203 to limit a position of the corresponding one of the position-buckled portions 222 disposed in the position-buckled notch 3201 in the vertical direction, so that each of the T-shaped buckling pins 22 and the position-buckled member 320 form a position-limited cooperation to achieve a connection of the corresponding one of the plurality of lapping units 32 and the corresponding one of the connecting members 2.

In this embodiment, each of the lapping members 3 is integrally formed by four lapping units 32 of the plurality of lapping units 32. A frontmost end of each of the lapping members 3 formed by the four lapping units 32 comprises an insertion member 321, and a rearmost end of each of the lapping members 3 comprises an insertion socket 322. The insertion member 321 of one of the lapping member 3 is inserted into the insertion socket 322 of another one of the lapping members 3 to form a lengthened lapping member so as to adjust a length of the lengthened lapping member 3. The lapping members 3 can be connected to form the lengthened lapping member by splicing according to a size of the elastic module.

More specifically, a thickness of the insertion member 321 is slightly thinner than a thickness of each of the lapping members 3. An elastic position-limited member 3211 is disposed on a side surface of the insertion member 321, and the elastic position-limited member 3211 has elasticity and can be pressed from a first position protruding from the side surface of the insertion member 321 to a second position aligned with the side surface of the insertion member 321. A front half of the elastic position-limited member 3211 defines a downwardly-inclined plane along a direction in which the insertion member 321 is inserted into the insertion socket 322. A thickness of the insertion socket 322 is slightly thicker than the thickness of each of the lapping members 3. A middle of the insertion socket 322 in a thickness direction comprises an insertion groove 3221 into which the insertion member 321 is inserted. A thickness of the insertion groove 3221 is greater than the thickness of the insertion member 321 and smaller than a total thickness of the insertion member 321 and the elastic position-limited member 3211. An inner side of the insertion groove 3221 comprises a position-limited structure configured to limit a position of the elastic position-limited member 3211, and the third position-limited structure can be a space on an inner wall of the insertion groove 3221 configured for popping out the elastic position-limited member 3211.

In this embodiment, when the lapping members 3 are lengthened, the insertion member 321 of a front end of one of the lapping members 3 is inserted into the insertion groove 3221 of the insertion socket 322 of a rear end of another one of the lapping members 3. During an inserting process, the elastic position-limited member 3211 is pressed by the inner wall of the insertion groove 3221 to be gradually aligned with the side surface of the insertion member 321 so as to be inserted into the insertion groove 3221. When the insertion member 321 is inserted into the insertion groove 3221 until the elastic position-limited member 3211 pops out and is limited by the inner wall of the insertion groove 3221, a connection between two of the lapping members 3 is achieved. Thereby, the lapping members 3 can be connected to form the lengthened lapping member having the eight lapping units 32 of the plurality of lapping units 32.

The plurality of pre-compressed springs 1 are respectively connected to two sides of the eight lapping units 32 to connect eight of the plurality of pre-compressed springs 1 together in series to form a row and connected to the plurality of pre-compressed springs 1 in two adjacent rows synchronously. Similarly, twenty rows of the eight of plurality of pre-compressed springs 1 are connected together to form the elastic module. The rest of Embodiment 2 is the same as Embodiment 1 and will not be described herein.

Embodiment 3

Referring to FIGS. 26-33, the plurality of pre-compressed springs 1 of this embodiment are the same as that of Embodiment 1. This embodiment mainly differs from Embodiment 1 in that two opposite sides of each of the connecting members 2 each comprises a buckling pin 23. Two cantilevered arms 230 are respectively disposed on two sides of the buckling pin 23. Each of the two cantilevered arms 230 is divided into a first part 2301 extending upward in a vertical direction and a second part 2302 extending outward in a horizontal direction. The first part 2301 comprise a second position-buckled structure 2303 extending outward in the horizontal direction, and the second position-buckled structure 2303 and the second part 2302 form a buckling groove 2304.

Two side surfaces of each of a plurality of lapping units 33 each comprises an insertion groove 330 acting as a position-buckled member. Two sides of the insertion groove 330 are inwardly hollowed out in the horizontal direction to enable two sides of an upper portion of the insertion groove 330 to form a position-limited portion 3301. After the buckling pin 23 is inserted into the insertion groove 330, the buckling groove 2304 and the position-limited portion 3301 form a position-limited cooperation in the vertical direction to limit positions of the buckling pin 23 and the insertion groove 330.

In this embodiment, the buckling pin 23 further comprises releasing members 231 configured to release from limiting the positions of the buckling pin 23 and the insertion groove 330. The two cantilevered arms 230 are respectively connected to two of the releasing members 231. The releasing members 231 push and pull the two cantilevered arms 230 to drive the second position-buckled structure 2303 to be buckled to or to be separated from the position-limited portion 3301 to limit a position of the buckling pin 23 using the insertion groove 330 as the position-buckled member and release the buckling pin 23.

When the plurality of pre-compressed springs 1 are connected, the releasing members 231 on two sides of the buckling pin 23 are pressed inward. The buckling pin 23 is then inserted into the insertion groove 330 from an upper side, and the releasing members 231 are released. At this time, the position-limited portion 3301 is buckled to the buckling groove 2304. A position of the buckling pin 23 is limited by the insertion groove 330 in the horizontal direction after being inserted into the insertion groove 330. At the same time, the second position-buckled structure 2303 is buckled to a lower end of the position-limited portion 3301, and the second part 2302 is buckled to an upper end of the position-limited portion 3301 to limit a position of the buckling pin 23 in the vertical direction, thereby achieving the connection of the connecting members 2 and the one or more lapping members 3.

When the plurality of pre-compressed springs 1 are disassembled, the releasing members 231 on the two sides of the buckling pin 23 are pressed inward to drive the second position-buckled structure 2303 to be separated from the position-limited portion 3301, and the buckling pin 23 is then pulled upward from the insertion groove 330 to release the connection of the connecting members 2 and the one or more lapping members 3.

In this embodiment, five of the plurality of lapping units 33 are integrally formed into a corresponding one of the one or more lapping members 3. The plurality of pre-compressed springs 1 are respectively connected to two sides of the five of the plurality of lapping units 33. The five of the plurality of pre-compressed springs 1 are connected in series to form a row and are connected to the plurality of pre-compressed springs 1 in two adjacent rows. Similarly, ten rows of the five of the plurality of pre-compressed springs 1 are connected each other through the one or more lapping members 3 to form the elastic module. The rest of Embodiment 3 is the same as Embodiment 1 and will not be described herein.

Embodiment 4

Referring to FIGS. 34-40, the plurality of pre-compressed springs 1 of this embodiment are the same as that of Embodiment 1. This embodiment differs from Embodiment 1 in that a first connecting structure and a third connecting structure are respectively disposed on two opposite sides of each of the connecting members 2, and the first connecting structure is different from the third connecting structure.

Specifically, a first extended portion 24 and a second extended portion 25 respectively extend outward from the two opposite sides of each of the connecting members 2. The first extended portion 24 on one side comprises a rotatable protrusion 241 configured to rotate about the first extended portion 24 and acting as a first connecting structure. The second extended portion 25 on another side comprises a recessed hole 251 into which the rotatable protrusion 241 can extend and acts as a third connecting structure.

In this embodiment, each of one or more lapping members 3 is integrally formed by sixteen of a plurality of lapping units 34. Each of the plurality of lapping units 34 comprises a connecting hole 341 into which the rotatable protrusion 241 can extend and acts as a second connecting structure.

When the plurality of pre-compressed springs 1 are connected, the rotatable protrusion 241 on one of the connecting members 2 extends into the connecting hole 341 on a corresponding one of the plurality of lapping units 34. At this time, positions of the rotatable protrusion 241 and the connecting hole 341 are limited in a horizontal direction, and the rotatable protrusion 241 rotates to be misaligned with the connecting hole 341. At this time, positions of the rotatable protrusion 241 and the connecting hole 341 are limited in a vertical direction to achieve a connection and the plurality of lapping units 34 and the connecting members 2. The plurality of pre-compressed springs 1 are respectively connected to the sixteen of the plurality of lapping units 34 of a corresponding one of the one or more lapping members 3, so that the plurality of pre-compressed springs 1 are connected in series to form rows.

When the plurality of pre-compressed springs 1 in two adjacent rows are connected, the rotatable protrusion 241 of each of the plurality of pre-compressed springs 1 in a rear row of the two adjacent rows is inserted into the recessed hole 251 of each of the plurality of pre-compressed springs 1 in a front row of the two adjacent rows that have been connected in series and the connecting hole 341 of each of the plurality of lapping units 34 of a corresponding one of the one or more lapping members 3, and the rotatable protrusion 241 then rotates to be misaligned with the recessed hole 251 and the connecting hole 341. At this time, a connection of the plurality of pre-compressed springs 1 in rear and front rows is achieved by a position-limited cooperation of the rotatable protrusion 241, the recessed hole 251, and the connecting hole 341. As a simple alternative of this embodiment, the plurality of pre-compressed springs 1 forming the rows by connecting in series through the one or more lapping members 3 and in the front and rear rows can be connected by directly extending the rotatable protrusion 241 of each of the plurality of pre-compressed springs 1 in the rear row into the recessed hole 251 of each of the plurality of pre-compressed springs 1 in the front row, and the rotatable protrusion 241 rotates to be misaligned with the recessed hole 251 to limit a position of the rotatable protrusion 241 for the connection.

When the plurality of pre-compressed springs 1 are disassembled, the rotatable protrusion 241 rotates to be aligned with the recessed hole 251 and the connecting hole 341, and the rotatable protrusion 241 can be taken out from a lower side.

In this embodiment, the sixteen of the plurality of lapping units 34 are integrally formed into a corresponding one of the one or more lapping members 3. The plurality of pre-compressed springs 1 are respectively connected to the sixteen of the plurality of lapping units 34, so that sixteen of the plurality of pre-compressed springs 1 are connected in series to form one or the rows. The rotatable protrusion 241 then extends into the recessed hole 251 and the connecting hole 341 of a corresponding one of the one or more lapping members according to the aforementioned connection method. The rotatable protrusion 241 rotates to be misaligned with the recessed hole 251 and the connecting hole 341 to connect the plurality of pre-compressed springs 1 in the two adjacent rows. Similarly, seven rows of the sixteen of the plurality of pre-compressed springs 1 are connected to each other through the one or more lapping members 3 to form the elastic module. The rest of Embodiment 4 is the same as Embodiment 1 and will not be described herein.

A number of the plurality of lapping units of the one or more lapping members 3, a number of the plurality of pre-compressed springs 1 connected in series to form the rows, a number of the rows of the plurality of pre-compressed springs 1, a connection sequence of the one or more lapping members 3 and the plurality of pre-compressed springs 1, and the like can be adjusted according to a size of the elastic module or requirements of the user and the disclosure is not limited to what is mentioned in Embodiments 1-4.
