FIELD OF THE DISCLOSURE

The present disclosure relates to the field of furniture, and in particular to an elastic cushion.

BACKGROUND OF THE DISCLOSURE

Mattresses are an essential piece of furniture in bedding for people in modern life. Especially as stress levels of people increase, elastic mattresses containing elastic components are becoming increasingly popular as a means of providing relaxation during sleep. Most of the elastic components of existing elastic mattresses include pocket springs independent to each other. Each of the pocket springs is individually packaged in a spring pocket, then the spring pockets are arranged in a pattern, and then the arranged group of the spring pockets is covered with a whole piece of foam rubber to form an overall elastic mattress. This type of elastic mattress cannot be disassembled and is not easy to transport.

Therefore, mattresses in which the springs in the mattress can be disassembled have been developed. However, during handling and transportation, the removed springs are always in a released state, which takes up a lot of space and manpower for transportation. When the springs need to be fixed in a compressed state for transportation, a fixing structure is required. However, this fixing structure is a rigid structure, which increases the hardness of a contact surface between the mattress and the user, resulting in reduced comfort.

The technical problem to be solved by the present disclosure is to provide an elastic module, which can achieve compressed storage of elastic units while also meeting comfort requirements.

In order to solve the above technical problems, the present disclosure provides an elastic module, comprising a base plate and a plurality of elastic units arranged on the base plate in an array. Each of the plurality of elastic units comprises a fixed end and a flexible end.

The base plate comprises a plurality of locking structures configured to be interlocked with the fixed end, and the fixed end comprises a locking cooperation structure configured to be detachably matched with a corresponding one of the plurality of locking structures.

The release member is configured to drive the corresponding one of the plurality of locking structures to rotate relative to the locking cooperation structure along a circumferential direction of the locking cooperation structure, so as to release the interlocked connection between the corresponding one of the plurality of locking structures and the locking cooperation structure.

In a preferred embodiment, each of the plurality of locking structures comprises a plurality of ribs arranged at intervals along a circumferential direction of the corresponding one of the plurality of locking structures. A first end of each of the plurality of ribs is fixed on the base plate, and a second end of each of the plurality of ribs is a free end. An outer side surface of the free end is a first inclined surface.

In a preferred embodiment, the fixed end comprises a position-providing opening for the corresponding one of the plurality of locking structures to pass through, and an inner diameter of the position-providing opening is smaller than an outer diameter of each of the plurality of locking structures in a natural state.

In a preferred embodiment, a limiting surface is formed between a lower end of the first inclined surface and a body of a corresponding one of the plurality of ribs.

In a preferred embodiment, an inner wall of the position-providing opening forms a second inclined surface that cooperates with the first inclined surface, and an inclination direction of the second inclined surface is opposite to an inclination direction of the first inclined surface.

Each of the plurality of elastic units is configured to be placed on the plurality of middle rings in a second direction, so that a corresponding one of the plurality of elastic units is configured to be fixed in a compressed state through the interlocked connection between the corresponding one of the plurality of locking structures and the locking cooperation structure along a release direction of the corresponding one of the plurality of elastic units. The first direction and the second direction are opposite directions.

In a preferred embodiment, the elastic module comprises a release member. The release member is configured to drive the corresponding one of the plurality of locking structures to contract radially relative to the locking cooperation structure, so as to release the interlocked connection between the corresponding one of the plurality of locking structures and the locking cooperation structure.

Embodiment 1

Referring to FIGS. 1-11, this embodiment provides an elastic module, and the elastic module comprises a base plate 1 and a plurality of elastic units 2 arranged on the base plate 1 in an array. Each of the plurality of elastic units 2 comprises a fixed end 21 and a flexible end 22.

The base plate 1 comprises a plurality of locking structures 100 configured to be interlocked with the fixed end 21, and the fixed end 21 comprises a locking cooperation structure 200 configured to be detachably matched with a corresponding one of the plurality of locking structures 100.

In a released state, each of the plurality of elastic units 2 is placed on the base plate 1 in a first direction through an interlocked connection between the corresponding one of the plurality of locking structures 100 and the locking cooperation structure 200, so that the flexible end 22 is located away from the base plate 1. Each of the plurality of elastic units 2 is configured to be placed on the base plate 1 in a second direction through the interlocked connection between the corresponding one of the plurality of locking structures 100 and the locking cooperation structure 200 along a release direction of a corresponding one of the plurality of elastic units 2, so that the corresponding one of the plurality of elastic units 2 is fixed in a compressed state. The first direction and the second direction are opposite.

For the aforementioned plurality of elastic units 2, each of plurality of elastic units 2 comprises the fixed end 21 and the flexible end 22. During normal use of the plurality of elastic units 2, each of the plurality of elastic units 2 is connected to the base plate 1 through the fixed end 21, thereby orienting the flexible end 22 toward a user to enhance comfort. When the plurality of elastic units 2 are compressed for storage, each of the plurality of elastic units 2 is configured to be placed in an inverted direction (i.e., orienting the flexible end 22 toward the base plate 1), and then the fixed end 21 is connected to the base plate 1, thereby fixing the corresponding one of the plurality of elastic units 2 in the compressed state. This allows the plurality of elastic units 2 to be compressed for storage while ensuring user comfort during use.

In the aforementioned structure, when the plurality of elastic units 2 are in the compressed state, each of the plurality of elastic units 2 is fixed to the base plate 1 through the locking cooperation structure 200 of the fixed end 21 and the corresponding one of the plurality of locking structures 100 of the base plate 1. Therefore, once a fixed connection between the locking cooperation structure 200 of the fixed end 21 and the corresponding one of the plurality of locking structures 100 of the base plate 1 is released, not only can each of the plurality of elastic units 2 be restored to the released state, but each of the plurality of elastic units 2 in the released state can also be removed from the base plate 1. Thus, the user can rotate each of the plurality of elastic units 2 by 180° and then connect the fixed end 21 to the base plate 1 to complete installation of each of the plurality of elastic units 2 in the released state.

To restore the plurality of elastic units 2 to the released state, this embodiment further comprises a release member 3, and the release member 3 is configured to drive the corresponding one of the plurality of locking structures 100 to contract radially relative to the locking cooperation structure 200, thereby releasing the interlocked connection between the corresponding one of the plurality of locking structures 100 and the locking cooperation structure 200. As a simple alternative to this embodiment, the release member 3 can also be used to drive the corresponding one of the plurality of locking structures 100 to rotate circumferentially relative to the locking cooperation structure 200, thereby releasing the interlocked connection between the corresponding one of the plurality of locking structures 100 and the locking cooperation structure 200.

Specifically, each of the plurality of locking structures 100 comprises a plurality of ribs 11 arranged at intervals along a circumferential direction thereof. A first end of each of the plurality of ribs 11 is fixed to the base plate 1, and a second end of each of the plurality of ribs 11 is a free end. An outer side surface of the free end forms a first inclined surface 12, and a limiting surface 13 is formed between a lower end of the first inclined surface 12 and a body of a corresponding one of the plurality of ribs 11. Correspondingly, the fixed end 21 comprises a position-providing opening 23 for the corresponding one of the plurality of locking structures 100 to pass through. The position-providing opening 23 is the locking cooperation structure 200 in this embodiment. An inner diameter of the position-providing opening 23 is smaller than an outer diameter of the corresponding one of the plurality of locking structures 100 in a natural state (i.e., in a state that the corresponding one of the plurality of locking structures 100 is not compressed by the position-providing opening 23). This ensures that when the corresponding one of the plurality of locking structures 100 is not subjected to compression, the limiting surface 13 can be interlocked with an exterior of the position-providing opening 23 to achieve the interlocked connection. The design of the first inclined surface 12 allows the corresponding one of the plurality of locking structures 100 to cause the corresponding one of the plurality of ribs 11 to move inward due to being compressed by the position-providing opening 23 during a process of the corresponding one of the plurality of locking structures 100 passing through the position-providing opening 23, so that the corresponding one of the plurality of locking structures 100 can pass through the position-providing opening 23.

To ensure that the corresponding one of the plurality of ribs 11 can move inward due to being compressed by the position-providing opening 23 during the process of the corresponding one of the plurality of locking structures 100 passing through the position-providing opening 23, an inner wall of the position-providing opening 23 forms a second inclined surface 24 that cooperates with the first inclined surface 12. An inclination direction of the second inclined surface 24 is opposite to that of the first inclined surface 12.

Similarly, the release member 3 compresses the first inclined surface 12 to cause the corresponding one of the plurality of ribs 11 to move inward, thereby enabling the limiting surface 13 to be released from the exterior of the position-providing opening 23 (i.e., the locking cooperation structure 200).

Embodiment 2

Referring to FIGS. 12-22, the difference between this embodiment and Embodiment 1 is that the base plate 1 from Embodiment 1 is removed and replaced with a plurality of middle rings 4. The plurality of middle rings 4 comprise a plurality of locking structure configured to be interlocked with the fixed end 21.

This allows the plurality of elastic units 2 to be installed on an upper side and a lower side of the plurality of middle rings 4, forming a double-layer elastic module. This differs from the single-layer structure in Embodiment 1. Moreover, different needs can be met by individually releasing the plurality of elastic units 2 on an upper layer or a lower layer of the double-layer elastic module.

Embodiment 3

Referring to FIGS. 23-24, this embodiment provides an elastic cushion 10, comprising the elastic module 20 (e.g., the double-layer elastic module) described in Embodiment 2 and a soft cushion 30. Of course, the elastic module from Embodiment 1 can also be used.

The above descriptions are merely preferred specific implementations of the present disclosure and do not limit the patent scope of the present disclosure. Any technical equivalent transformations made based on the content of the description of the present disclosure shall fall within the protection scope of the present disclosure.
