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. A soft mattress, elastic components, and a base of the existing elastic bed mattresses having the elastic components are usually integrated to form a whole structure. Upper ends of springs are connected together, causing surrounding elastic components to be simultaneously stressed when a local stress is applied to the elastic mattress. Therefore, a range of the stress applied to the elastic components of the existing elastic mattresses cannot be adjusted following a body posture on the elastic mattress. Additionally, the stress applied to the elastic mattress cannot be adjusted according to a sleeping posture of a person to enable the elastic mattress to conform to a curve of a human body to be softer and more comfortable.

As a simple alternative to this embodiment, one or more outermost pre-compressed springs 10 of the plurality of pre-compressed springs 10 on the first one of the plurality of elastic modules 1 and one or more outermost pre-compressed springs 10 of the plurality of pre-compressed springs 10 on the second one of the plurality of elastic modules 1 can also be buckled to each other by the connecting members 11.

In order to judge a usage state and cleanliness of the elastic mattress during use and to clean the elastic mattress or replace parts of the elastic mattress in time according to the usage state, in this embodiment, the one or more upper mattress layers 2 are disposed on an upper side of the plurality of elastic modules 1 and the plurality of pre-compressed springs 10 are exposed to an external side, thereby enabling the elastic mattress to be an open structure. This allows the user to judge the cleanliness of the elastic mattress and wear level of the plurality of pre-compressed springs 10 in time through naked eyes during use.

In order to facilitate the user cleaning the elastic mattress and replacing the parts of the elastic mattress, as shown in FIGS. 10-13, in this embodiment, strips 20 having pull buckles are disposed on a periphery of the one or more upper mattress layers 2, and the strips 20 having pull buckles are buckled to corresponding lap joints 12 of the one or more lap joints 12 connected to the one or more outermost pre-compressed springs 10 of the elastic mattress to achieve a detachable connection of the one or more upper mattress layers 2 and the plurality of elastic modules 1.

In this embodiment, the one or more outermost pre-compressed springs 10 of the elastic mattress do not need to be connected to another one of the plurality pf elastic modules 1, and adjacent ones of the one or more outermost pre-compressed springs 10 of the elastic mattress and a corresponding one of the strips 20 having pull buckles of the one or more upper mattress layers 2 are connected together by a three-way lap joint 13. The three-way lap joint 13 comprises a fixed seat 131 and three knobs 132 identical to the knobs 122, and the three knobs 132 comprise three grooves 133. Corresponding ones of the T-shaped protrusions 114 on the adjacent ones of the one or more outermost pre-compressed springs 10 of the elastic mattress and a T-shaped protrusion 201 of the corresponding one of the strips 20 having pull buckles are respectively buckled to the three grooves 133 of the three-way lap joint 13. The knobs 132 rotate to lock the T-shaped protrusion 201 and the corresponding ones of the T-shaped protrusions 114 to realize a fixed connection of the one or more outermost pre-compressed springs 10 of the elastic mattress and to secure the one or more upper mattress layers 2 with the plurality of elastic modules 1. As a simple alternative to this embodiment, the strips 20 having pull buckles can also comprise grooves for a direct connection with the T-shaped protrusions 114 of the connecting members 11.

In this embodiment, according to different needs of the user for softness of the elastic mattress, the one or more upper mattress layers 2 comprise a plurality of mattress layers with different softness or hardness. The user can combine mattress layers having appropriate hardness to form one or more suitable upper mattress layers 2 according to actual needs and preferences for softness of the one or more upper mattress layers 2. A surface of the one or more upper mattress layers 2 can also use leather, ultrafine fiber, cotton, wool, or other materials. As a simple alternative of this embodiment, the one or more upper mattress layers 2 can also be an integrated structure.

Referring to FIGS. 14-27, in this embodiment, the one or more bottom layers 3 are spliced by a plurality of bottom layer units 30. In order to enable the plurality of pre-compressed springs 10 to be connected to the one or more bottom layers 3, the one or more bottom layers 3 comprise a plurality of positioning protrusions 31 as fixing members 311, and lower end surfaces of the plurality of pre-compressed springs 10 comprise a plurality of cavities 1022 positioned at and cooperating with the plurality of positioning protrusions 31. Therefore, the plurality of pre-compressed springs 10 are connected to the one or more bottom layers 3 using a male-female connection of the plurality of positioning protrusions 31 and the plurality of cavities 1022.

Corresponding ones of the one or more bottom layers 3 form a size as each of the plurality of elastic modules 1 by splicing the plurality of bottom layer units 30 together through connecting knobs 32 (i.e., third members 320). Each of the connecting knobs 32 is a circular knob, and a bottom of each of the circular knobs 32 comprises two T-shaped buckling pins 321 symmetrical to each other. Edges of the plurality of bottom layer units 30 comprise sliding rails 301 configured to be positioned at and cooperate with the two T-shaped buckling pins 321 of each of the connecting knobs 32. Widths of the sliding rails 301 narrow along a rotation direction of the connecting knobs 32, allowing the two T-shaped buckling pins 321 of each of the connecting knobs 32 to be respectively buckled to wide parts of corresponding sliding rails 301 of two adjacent bottom layer units 30 of the plurality of bottom layer units 30. A handle on each of the connecting knobs 32 rotates to enable each of the connecting knobs 32 to rotate until the two T-shaped buckling pins 321 are positioned at narrow parts of the corresponding sliding rails 301, and a connection of the two adjacent bottom layer units 30 is achieved.

As a simple alternative of this embodiment, the corresponding ones of the one or more bottom layers 3 can also be an integrated structure to match the size of each of the plurality of elastic modules 1. At the same time, the plurality of pre-compressed springs 10 are connected together in each of the plurality of elastic modules 1, so that the plurality of positioning protrusions 31 can be located only on some of the bottom layer units 30 on a periphery of the one or more bottom layers 3.

In this embodiment, the elastic mattress is spliced by the plurality of elastic modules 1, and a plurality of bottom layers 3 of the one or more bottom layers 3 connected to the plurality of elastic modules 1 are detachably connected to form a base of the elastic mattress using the connecting knobs 32. Therefore, a specific number of the plurality of elastic modules 1 and the bottom layers 3 that are detachably connected together are spliced together to form the elastic mattress according to actual size requirements of the user.

A size of each of the plurality of bottom layer units 30 can be set arbitrarily, and one of the plurality of bottom layer units 30 can be connected to one or more of the plurality of pre-compressed springs 10. The plurality of bottom layers 3 can be formed by splicing the plurality of bottom layer units 30 with different sizes together through the connecting knobs 32, or by splicing the plurality of bottom layer units 30 with same sizes together through the connecting knobs 32. As a simple alternative of this embodiment, the plurality of bottom layer units 30 and the plurality of bottom layers 3 can also be detachably connected to each other using a plug-in connection, a hinge, etc.

Specifically, the plurality of bottom layers 3 can be formed by splicing a plurality of 8-seat bottom layer units 30 and/or a plurality of 4-seat bottom layer units 30 of the plurality of bottom layer units 30 together, or by splicing a plurality of 5-seat bottom layer units 30 of the plurality of bottom layer units 30 together, or by splicing a plurality of 1-seat bottom layer units 30 and/or a plurality of 5-seat bottom layer units 30 of the plurality of bottom layer units 30 together. A seat number of the plurality of bottom layer units 30 and a combination for splicing are not limited to the description mentioned in this embodiment.

Referring to FIGS. 28-29, in this embodiment, in order to facilitate transportation or relocation of the elastic mattress after disassembly, the plurality of pre-compressed springs 10 can be compressed to a locked state. A height of the plurality of pre-compressed springs 10 compressed to the locked state is greatly reduced, and occupied space is reduced to facilitate the transportation and the relocation. More specifically, each of the plurality of pre-compressed springs 10 comprises a top cover 101 and a bottom cover 102. The top cover 101 comprises a first positioning structure 1011, the bottom cover 102 comprises a second positioning structure 1021, and the first positioning structure 1011 is detachably buckled to the second positioning structure 1021. A lower end surface of the bottom cover 102 of each of the plurality of pre-compressed springs 10 comprises a corresponding one of the plurality of cavities 1022 positioned at and cooperating with a corresponding one of the plurality of positioning protrusions 31. The bottom cover 102 defines a top surface of the corresponding one of the plurality of cavities 1022, and the second positioning structure 1021 is discontinuous flanges disposed on an outer periphery of an upper end of the corresponding one of the plurality of cavities 1022. Each of the plurality of pre-compressed springs 10 is compressed using an external force to enable hooks of the first positioning structure 1011 and the discontinuous flanges of the second positioning structure 1021 to be buckled together, thereby achieving a compression (i.e., a locked state) of the plurality of pre-compressed springs 10. The external force can then be used to enable each of the plurality of pre-compressed springs 10 to rotate to enable the first positioning structure 1011 to rotate to be separated from the second positioning structure 1021 to achieve releasing of each of the plurality of pre-compressed springs 10 from the locked state.

The aforementioned description of the specification and the embodiments is used to explain the protection scope of the present disclosure instead of a limitation of the protection scope of the present disclosure. Modifications, equivalent substitutions, or other improvements of the embodiments or some technical features thereof of the present disclosure fall within the protection scope of the present disclosure provided that they are obtained by a person of ordinary technical skill in the art through logical analysis, reasoning, or limited experiments by combining common knowledge and ordinary technical knowledge in the art and/or the existing techniques through the hint of the present disclosure or the aforementioned embodiments.
