FIELD OF THE DISCLOSURE

The present disclosure relates to the field of furniture, and in particular to a spring module, a method for releasing the spring module, and an elastic cushion.

BACKGROUND OF THE DISCLOSURE

In modern life, mattresses are an indispensable piece of furniture in people's bedding. Especially with the increase of life pressure on people, in order to relax during sleep, elastic mattresses with elastic parts in a middle of the elastic mattresses are becoming more and more popular. The elastic parts of the existing elastic mattresses mostly use independent pocket springs. Each spring is individually packaged in a spring bag, and then the spring bags are arranged in a pattern. Then, the arranged spring bags are covered by a whole piece of foam rubber to form an elastic mattress as a whole. This kind of elastic mattress cannot be disassembled and is not easy to transport. Therefore, a mattress with detachable springs has been developed. However, during a handling and transportation process, the disassembled springs are always in a released state, which takes up a lot of space and manpower for handling.

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 one by one, which is time-consuming, labor-intensive, and inconvenient.

Embodiment 1

Referring to FIGS. 1 to 5, this embodiment provides a spring module, and the spring module comprises a plurality of elastic units arranged in an array. Each of the plurality of elastic units comprises a spring 1, a base 2 disposed at a lower end of the spring 1, and an upper cover 3 disposed at an upper end of the spring 1. Each of the plurality of elastic units further comprises an intermediate flexible strap 4, and the intermediate flexible strap 4 is connected to the base 2 and the upper cover 3.

The upper cover 3 comprises a channel 31 penetrating through the upper cover 3 and extending along a length direction of the intermediate flexible strap 4, so that the upper cover 3 has translational freedom relative to the intermediate flexible strap 4 along a direction toward the base 2. To fix the spring 1 in a compressed position, the intermediate flexible strap 4 is provided with a buckling member 41. When the spring 1 is in a released state, the buckling member 41 is located on an outside of the upper cover 3 and below the upper cover 3. When the spring 1 is in a compressed state, the upper cover 3 and the buckling member 41 move relative to each other, so that the buckling member 41 is placed in the channel 31, and the buckling member 41 is interlocked with the channel 31 in a direction of releasing the spring 1.

That is, when the spring 1 is in the released state, the buckling member 41 will not enter the channel 31 of the upper cover 3. After the spring 1 is compressed, the buckling member 41 will be placed in the channel 31 to be interlocked with the channel 31 through interference fit.

In this embodiment, to achieve the above-mentioned interlocked connection, the buckling member 41 is arranged on a side wall of the intermediate flexible strap 4 and extends outward along a radial direction of the intermediate flexible strap 4. When the spring 1 is in the compressed state, the buckling member 41 is placed in the channel 31 and is in interference fit with an inner wall of the channel 31.

To achieve pre-compressing the spring 1 by the intermediate flexible strap 4, a top of the intermediate flexible strap 4 extends radially outward to form a protruding edge 42. A width of the protruding edge 42 is greater than a width of the channel 31, so that the intermediate flexible strap 4 is interlocked with the upper cover 3 in a direction away from the base 2. In this way, by adjusting a length of the intermediate flexible strap 4, a distance between the upper cover 3 and the base 2 can be changed, so that the spring 1 is in a pre-compressed state.

To fix the intermediate flexible strap 4 and the base 2, a bottom of the intermediate flexible strap 4 protrudes radially outward to form an insertion portion having an inverted conical shape. The base 2 has an insertion hole configured to be matched with the insertion portion.

In this embodiment, the spring module comprises a connecting member 6 enabling the plurality of elastic units to be connected together.

The present embodiment also provides a method for releasing the spring module as described above, using an external force to pull the upper cover 3 so that the interlocked connection of the buckling member 41 and the channel 31 of the upper cover 3 are released, thereby releasing a single one of the springs 1 of the spring module, and adjacent springs 1 are released successively due to a restoring force of the single one of the springs 1, so that an entire row or group of the springs 1 is released to be in the released state.

Embodiment 2

Referring to FIGS. 6-8, this embodiment provides a spring module, and the spring module comprises a plurality of elastic units arranged in an array. Each of the plurality of elastic units comprises a spring 1 (i.e., the same as the spring 1 in Embodiment 1), a base 2 disposed at a lower end of the spring 1, an upper cover 3 disposed at an upper end of the spring 1, and an intermediate flexible strap 4. The intermediate flexible strap 4 is connected to the base 2 and the upper cover 3. The intermediate flexible strap 4 enables the spring 1 located between the base 2 and the upper cover 3 to have a pre-compressed force through the base 2 and the upper cover 3.

To fix the spring 1 in a compressed position, the present embodiment further comprises a fastening member 5, and the fastening member 5 is arranged at an upper end of an entire row of the springs 1 of the spring module, and the fastening member 5 comprises a plurality of pressing caps 51 corresponding to each spring 1 of the entire row of the springs 1.

Each of the plurality of pressing caps 51 comprises a first channel 511 penetrating therethrough along a length direction of the intermediate flexible strap 4, and the upper cover 3 comprises a second channel 31 penetrating therethrough along the length direction of the intermediate flexible strap 4, so that each of the plurality of pressing caps 51 and the upper cover 3 of a corresponding one of the plurality of elastic units have translational freedom relative to the intermediate flexible strap 4 in direction toward the base 2. Therefore, each of the plurality of pressing caps 51 can be pressed to drive a corresponding one of the plurality of pressing caps 51 and the upper cover 3 of the corresponding one of the plurality of elastic units to move downward, thereby compressing the spring 1 of the corresponding one of the plurality of elastic units. A width of the first channel 511 of each of the plurality of pressing caps 51 is smaller than a width of the second channel 31 of the upper cover 3 to avoid the first channel 511 on each of the plurality of pressing caps 51 from shielding the second channel 31 on the upper cover 3 of the corresponding one of the plurality of elastic units, thereby affecting fixing of the spring 1 in a compressed state in a subsequent process.

In this embodiment, the intermediate flexible strap 4 comprises two buckling members 41 arranged at intervals. When the spring 1 is in a released state, the two buckling members 41 are located on an outside of the upper cover 3 and below the upper cover 3. When the spring 1 is in the compressed state, the two buckling members 41 are respectively placed above and below the first channel 511, and the two buckling members 41 are interlocked with the first channel 511 in a direction of releasing the spring 1.

That is, when the spring 1 is in the released state, the two buckling members 41 will not be interlocked with the first channel 511 of the corresponding one of the plurality of pressing caps 51. After the spring 1 is compressed, one of the two buckling members 41 will pass through the first channel 511, and the two buckling members 41 are located above and below the first channel 511 to achieve an interlocked connection. To achieve such a structure, a side wall of the first channel 511 of the corresponding one of the plurality of pressing caps 51 comprises an opening 512 connected to the first channel 511, and a width of the opening 512 gradually increases along a direction away from the first channel 511 to define a position-providing opening. The two buckling members 41 are two position-limiting protrusions arranged on a side wall of the intermediate flexible strap 4 and extending along a direction away from the intermediate flexible strap 4. When the spring 1 is compressed, a lower one of the two position-limiting protrusions passes through the first channel 511 of the corresponding one of the plurality of pressing caps 51 through the position-providing opening, and a part of the intermediate flexible strap 4 located between two position-limiting protrusions enters the first channel 511 through the opening 512, so that after the spring 1 is compressed, the two position-limiting protrusions are respectively located above and below the first channel 511.

To achieve pre-compressing the spring 1 by the intermediate flexible strap 4, a top of the intermediate flexible strap 4 extends radially outward to form a protruding edge 42, and a width of the protruding edge 42 is greater than the width of the second channel 31, so that the intermediate flexible strap 4 is interlocked with the upper cover 3 in a direction away from the base 2. In this way, by adjusting a length of the intermediate flexible strap 4, a distance between the upper cover 3 and the base 2 can be changed, so that the spring 1 is in a pre-compressed state.

To fix the intermediate flexible strap 4 and the base 2, a bottom of the intermediate flexible strap 4 protrudes radially outward to form an insertion portion 43 having an inverted conical shape. The base 2 has an insertion hole 21 configured to be matched with the insertion portion 43.

The present embodiment also provides a method for releasing the spring module as described above, using an external force to pull the fastening member 5 so that the two buckling members 41 and the first channel 511 are released from the interlocked connection, thereby releasing a single one of the springs 1 of the spring module, and adjacent springs are released successively due to a restoring force of the single one of the springs 1, so that the entire row or group of the springs 1 is released to the released state.

Embodiment 3

Referring to FIGS. 9-11, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, there is only one spring 1 in each of the plurality of elastic units, while the spring 1 in Embodiment 1 is divided into a first sub-spring and a second sub-spring (i.e., the same as the first sub-spring 11 and the second sub-spring 12 in Embodiment 5), and a middle ring 13 is connected to the first sub-spring and the second sub-spring. The middle ring 13 comprises a position-providing opening 131 for the intermediate flexible strap 4 to pass through.

Embodiment 4

Referring to FIG. 12, the difference between this embodiment and Embodiment 2 is that the plurality of pressing caps are eliminated, and the second channel 31 of the upper cover 3 has a same structure as the first channel 511 in Embodiment 2. The spring 1 is fixed in the compressed position by cooperation between the second channel 31 of the upper cover 3 and the two buckling members 41.

Embodiment 5

Referring to FIG. 13, the difference between this embodiment and Embodiment 4 is that the spring 1 is divided into a first sub-spring 11 and a second sub-spring 12, and a middle ring 13 is connected to the first sub-spring 11 and the second sub-spring 12. The middle ring 13 comprises a position-providing opening 131 for the intermediate flexible strap 4 to pass through.

Embodiment 6

Referring to FIG. 14, the difference between this embodiment and Embodiment 5 is that the design of two springs 1 (i.e., the first sub-spring 11 and the second sub-spring 12) is not present, but the middle ring 13 arranged in a middle of the spring 1 is retained. The middle ring 13 comprises a position-providing opening 131 for the intermediate flexible strap 4 to pass through.

Embodiment 7

Referring to FIG. 15, the difference between this embodiment and Embodiment 6 is that the intermediate flexible strap 4 comprises two second buckling members 44 arranged at intervals, and the two buckling members 41 and the two second buckling members 44 are respectively located above and below the middle ring 13. When the spring 1 is in the compressed state, the two second buckling members 44 are placed above and below the insertion hole 21 of the base 2, and the two second buckling members 44 are interlocked with the insertion hole along the direction of releasing the spring 1. In this way, stability of each of the plurality of elastic units in the compressed state can be increased by the two buckling members 41 and the two second buckling members 44. The intermediate flexible strap 4 is fixed on the middle ring 13.

Embodiment 8

Referring to FIG. 16, the difference between this embodiment and Embodiment 4 is that each of the plurality of elastic units comprises a plurality of intermediate flexible straps 4, and tops of the plurality of intermediate flexible straps 4 are connected together by the protruding edge 42.

Embodiment 9

Referring to FIG. 17-FIG. 18, the difference between this embodiment and Embodiment 4 is that: each of the plurality of elastic units comprises a top spring 14 based on Embodiment 4, and the spring 1 is used as a bottom spring. A height of the top spring 14 is less than that of the bottom spring, so that when storing, there is no need to compress the top spring 14, only the bottom spring needs to be compressed. The structure of compressing and releasing the bottom spring is the same as that of Embodiment 4 and will not be described in detail.

This embodiment also provides an elastic cushion, comprising a soft cushion and the elastic spring described in any one of Embodiments 1-9.

The above is only a preferred specific implementation of the present disclosure, but the design concept of the present disclosure is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present disclosure within the technical scope disclosed by the present disclosure shall be deemed to infringe the protection scope of the present disclosure.
