Description

Technical Field

[0001] The present invention relates to the technical field of mattresses, and in particular to a mattress and an elastic supporting mechanism thereof. Background Art

[0002] A mattress is an item placed between the human body and the bed to ensure a comfortable sleep. Mattresses are divided into spring mattresses, palm mattresses, latex mattresses, and airbag mattresses according to the different cushion cores.

[0003] The cushion core of the airbag mattress is composed of multiple airbags, and the airbags are interconnected through pipes. Each airbag is filled with a preset amount of gas for support. The airbag has multiple retractable annular parts, which are connected in series and interconnected. When the user is on the upper surface of the airbag mattress, some of the airbags are subjected to pressure from top to bottom, and the gas in the compressed airbags diffuses to the uncompressed airbags. The annular parts of the compressed airbags are compressed, and the support height of the part of the airbag mattress corresponding to the user's body decreases, so that the user's body fits the airbag mattress to improve comfort. For users with a large body weight, the user's pressure on the airbag is greater, causing the compressed airbag to discharge more gas to the uncompressed airbag, and the compressed airbag shrinks to a greater extent, resulting in reduced support for the user. Sleeping on this airbag mattress for a long time will cause discomfort in the lumbar spine, and long-term use will also affect the health of the spine. Summary of the invention

Therefore, the above terms should not be understood as limiting the present invention.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] refer to Figures 1 to 7 A mattress according to a preferred embodiment of the present invention will be described in detail below, and the mattress includes a plurality of elastic support mechanisms 10 and a flexible outer cover 20. The plurality of elastic support mechanisms 10 are wrapped and installed in a hidden cavity 201 formed by the flexible outer cover 20 in a vertical arrangement.

[0030] In one example, the flexible cover 20 is implemented to include sponge.

[0031] refer to Figure 4 , each of the elastic support mechanisms 10 includes an inflatable support assembly 11. The inflatable support assembly 11 includes a top plate 111, a bottom plate 112 and a telescopic component 113. The telescopic component 113 includes a telescopic barrel 1131. The top plate 111 and the bottom plate 112 are arranged opposite to each other and are respectively installed on the two ends of the telescopic barrel 1131, and the top plate 111, the bottom plate 112 and the telescopic barrel 1131 together form a sealed inflatable space 1101. The inflatable support assembly 11 also forms at least one communicating hole 1102 connected to the inflatable space 1101. The communicating hole 1102 allows gas to pass through.

[0032] Specifically, the gas may enter the gas-filled space 1101 through the connecting hole 1102 ; the gas in the gas-filled space 1101 may also be discharged through the connecting hole 1102 .

[0033] In one embodiment, each of the telescopic barrels 1131 includes a plurality of support portions 11311 and a plurality of bag portions 11312. The plurality of bag portions 11312 and the plurality of bag portions 11312 are arranged at intervals from each other. The top plate 111 and the bottom plate 112 are connected to the support portions 11311 or the bag portions 11312, respectively. It is worth mentioning that the hardness of the support portion 11311 is higher than that of the bag portion 11312, and the support portion 11311 provides rigid support in the vertical direction. The bag portion 11312 can be telescoped in the vertical direction.

[0034] It is understandable that when the user is located on the upper surface of the mattress, the elastic support mechanism 10 corresponding to the user's position is subjected to a force from top to bottom, so that the gas in the inflatable space 1101 formed by the corresponding inflatable support component 11 is discharged outward through the connecting hole 1102. At this time, the sac part 11312 is compressed due to the loss of gas support, and then the support height of the corresponding inflatable support component 11 moves down, so that the mattress fits the user's body. At the same time, the support part 11311 provides the user with a vertical upward support force, so that the mattress has both comfort and softness while improving support. When the user leaves the mattress, the gas enters the inflatable space 1101 through the connecting hole 1102 formed by the inflatable support component 11 whose support height moves down, and the inflatable support component 11 recovers under the support of the gas, and the upper surface of the mattress becomes flat again.

[0035] Preferably, the heights of the multiple supporting parts 11311 provided on each of the single telescopic barrels 1131 gradually increase from top to bottom.

[0036] When a heavier user uses the mattress, the user exerts greater pressure on the mattress, causing the inflatable support assembly 11 corresponding to the user's position to be subjected to a greater top-down force. Since the height of the multiple support portions 11311 provided on the single telescopic cylinder 1131 gradually increases from top to bottom, the buffering effect of the support portions 11311 distributed from top to bottom on the pressure gradually becomes more obvious, causing the pressure on the bladder portions 11312 distributed from top to bottom to gradually decrease, and then the degree of elastic contraction of the bladder portions 11312 distributed from top to bottom gradually decreases. The corresponding downward movement of the support height of the inflatable support assembly 11 is reduced relative to the previous embodiment, so the inflatable support assembly 11 can also provide good support for users with heavy weight. It can be seen that the inflatable support assembly 11 can automatically adjust the support height and support force according to the user's weight to improve the adaptive ability of the mattress.

[0037] Preferably, the bottom plate 112 forms the connecting hole 1102, and when the inflatable support assembly 11 is under pressure, the gas in the inflatable space 1101 flows from top to bottom, thereby improving the comfort of the mattress when in use.

[0038] Preferably, the telescopic component 113 is further provided with at least one layer of auxiliary cylinder body 1132. The auxiliary cylinder body 1132 is sleeved with the telescopic cylinder body 1131, and the auxiliary cylinder body 1132 and the telescopic cylinder body 1131 are interconnected. In other words, the gas in a single inflatable support assembly 11 can flow in the auxiliary cylinder body 1132 and the telescopic cylinder body 1131 provided therein.

[0039] In a preferred embodiment, the communication hole 1102 formed by the inflatable support component 11 is only connected to the gap between the auxiliary cylinder body 1132 and the telescopic cylinder body 1131. In this way, when the inflatable support component 11 is under pressure, the gas in the auxiliary cylinder body 1132 or the telescopic cylinder body 1131 needs to pass through the gap between the auxiliary cylinder body 1132 and the telescopic cylinder body 1131 and then be discharged from the communication hole 1102, which prolongs the flow path of the gas, thereby reducing the speed and amplitude of the downward movement of the support height of the inflatable support component 11, avoiding a sudden change in the support height of the inflatable support component 11 when the user changes his posture, making the mattress change more stably when the user sits, lies down or turns over, and improving the user's use experience.

[0040] In one embodiment, reference Figure 6 The auxiliary cylinder body 1132 adopts the same design as the telescopic cylinder body 1131, so as to improve the support and strength of the inflatable support assembly 11.

[0041] As a variant, reference Figure 7 The auxiliary cylinder body 1132 has a plurality of annular portions 11321 , the plurality of annular portions 11321 are connected in series, and each of the annular portions 11321 can be extended and retracted in the vertical direction.

[0042] Furthermore, each of the elastic support mechanisms 10 also includes a metal support member 12. The metal support member 12 can be installed in a vertically telescopic manner in the space formed by the auxiliary cylinder body 1132 or the telescopic cylinder body 1131, and the two ends of the metal support member 12 are respectively in contact with the top plate 111 and the bottom plate 112. When the elastic support mechanism 10 is compressed, the metal support member 12 is compressed and has a tendency to return to its original length. In this way, when the user moves away from the mattress, the inflatable support assembly 11 quickly recovers under the elastic force of the metal support member 12, thereby shortening the time required for the mattress to recover.

[0043] In one example, the metal support 12 is implemented as a spring.

[0044] Those skilled in the art can understand that the elastic support mechanism 10 can be provided with the metal support member 12 and / or the auxiliary barrel 1132 according to elastic requirements.

[0045] Preferably, a first limiting groove 11101 is formed on one side of the top plate 111 facing the bottom plate 112, and a second limiting groove 11201 is formed on one side of the bottom plate 112 facing the top plate 111. The top and bottom of the metal support 12 are respectively inserted into the first limiting groove 11101 and the second limiting groove 11201. The groove wall of the first limiting groove 11101 and the groove wall of the second limiting groove 11201 respectively limit the two ends of the metal support 12 to reduce the shaking of the metal support 12 due to pressure.

[0046] Furthermore, the mattress also includes a plurality of connecting pipes 30 .

[0047] The communication pipe 30 is connected to the communication hole 1102 formed in the inflatable support assembly 11. The inflatable support assemblies 11 arranged in a row along the length of the mattress are connected to each other through the communication pipe 30.

[0048] It can be understood that when the user is located on the upper surface of the mattress, the elastic support mechanism 10 corresponding to the user's position is subjected to pressure from top to bottom, and different parts of the human body exert different pressures on the mattress: some of the elastic support mechanisms 10 are subjected to greater pressure, such as the elastic support mechanism 10 corresponding to the user's hip position; and some of the elastic support mechanisms 10 are subjected to less pressure, such as the elastic support mechanism 10 corresponding to the user's waist and neck position. At this time, part of the gas discharged from the compressed elastic support mechanism 10 diffuses into the uncompressed elastic support mechanism 10 through the connecting pipe 30, and the capacity of the inflatable support assembly 11 is limited. When the internal pressure of the uncompressed elastic support mechanism 10 is greater than that of the elastic support mechanism 10 corresponding to the user's waist and neck position, the gas discharged from the elastic support mechanism 10 corresponding to the user's hip position diffuses into the elastic support mechanism 10 with less pressure, thereby enhancing the support of the elastic support mechanism 10 corresponding to the user's waist and neck position to the waist and neck of the human body, so as to enhance the protection of the user's body and conform to ergonomics.

[0049] Preferably, a mounting groove 11202 is formed on a side of the bottom plate 112 facing away from the top plate 111. The mounting groove 11202 corresponds to the position of the connecting hole 1102. Part of the connecting pipe 30 is clamped in the mounting groove 11202, and the remaining part of the connecting pipe 30 passes between two adjacent rows of the elastic support mechanisms 10 to prevent the pipeline from being compressed and blocking the gas flow.

The advantages of the present invention have been fully and effectively achieved.
