Mattress core with replaceable inner blocks

A mattress core with replaceable inner blocks includes a base, an open slot A located in the upper portion of the base, an open slot B located in the lower portion of the base, an inner block located within slot B and shaped to partially fill up slot B with the remaining space forming a groove in slot B, a strip-shaped inner block made of soft material and fit into the groove, and a cover plate configured to fit in said slot A.

BACKGROUND OF THE INVENTION

Field of the Invention

The instant disclosure is generally related to mattress cores and more specifically to a mattress core with replaceable inner blocks.

People generally spend one third of their time in bed. Along with improvements in living condition, we expect better quality of life. Therefore, the mattress, as the most important part of a bed and directly contacts with the human body, plays a critical role for human's healthy sleep. A conventional mattress purchased and/or used by a consumer includes an internal structure that typically cannot be changed. As a result, integrated traditional mattress cannot meet the diverse needs of different users. During sleep, a person typically sleeps sideways for half of their sleep period. But in a sideway sleep position, because the human shoulder is broader than other parts of body, it takes more pressure. This higher pressure to the arm placed against the mattress often leads to numbness and stiffness. Customers suffer discomfort or even illness because of this. When two persons are hugging one of the other for sleep, it often causes pain, numbness or stiffness to the one who is holding the other because he or she has to cross his or her arms underneath the other and remain pressed by the other for a long period of time.

SUMMARY

In order to overcome the deficiencies of the prior art, the present disclosure provides a mattress core with replaceable inner blocks. It converts the traditionally integrated mattress core into multiple modular blocks so that the inner blocks can be replaced as needed. Further the present inventions provide an inner module design with a groove, which is suitable for placing in arm through. The groove, which allows for placement of the shoulder and arm lying against the bed, allows for more even weight distribution, rather than placing a disproportionate amount of weight on the arm and shoulder against the bed. It reduces the pressure. The holding person will no longer feel uncomfortableness, stiffness or numbness.

A preferred embodiment of the present inventions includes a base, an open slot A located in the upper portion of the base, an open slot B located in the lower portion of the base, an inner block located within slot B and shaped to partially fill up slot B with the remaining space forming a groove in slot B, and a cover plate configured to fit in said slot A.

The inner block is made of at least one piece.

The inner block is further a replaceable inner block, made of sponge, spring, or palm.

Another preferred embodiment of the present inventions further comprises a strip-shaped inner block in said groove.

The strip-shaped inner block is made of soft material.

The cover plate in a preferred embodiment matches the shape of said slot A, and said inner block in said slot B is in close contact with said strip-shaped inner block and the combination of the inner block and strip-shaped inner block matches the shape of said slot B.

The horizontal length and width of said slot A is larger or equal to the horizontal length and width of said slot B.

The inner block in a preferred embodiment is made of a first half block and a second half block and said first and second half blocks are in close contact with each other; and the base is made of a first half base and a second half base and includes two half base: first half base and second half base said first and second bases are in close contact with each other.

The material for said first half block can be the same or different from the material for said inner half block.

A technical advantage of the present inventions is splitting a traditionally integrated mattress core into a plurality of modules. So that the inner core can be replaced as needed. The model provides a groove, suitable for laying an arm inside. By adopting the present inventions, when someone is laying one side, his shoulder and arms won't be pressured by the weight of his or her body. When two persons are holding each other while lying in the bed, the shoulder and arm of the person holding, the other will no longer be pressed by the weight of the other. It reduces the pressure. The holding person will no longer feel uncomfortableness, stiffness or numbness. Therefore, the advantages of the present inventions include the benefit of replaceable inner blocks. It provides a comfortable solution for laying the arms in the groove while one person sleeping sideway or holding another person. The solutions disclosed herein are practical and beneficial. It has great potential for the consumer market.

DETAILED DESCRIPTION

FIG. 1-5shows two preferred embodiments of a mattress core with replaceable inner blocks. It include a base6, a slot A4is located in the upper portion of the base6, a slot B5is located under slot A in the lower portion of the base6. An inner block2is located within the slot B5. There may be one or more inner blocks2in slot B5. Inner block2can be made of sponge, spring, or palm. The space between the inner block2and the slot B5forms a groove7. A strip-shaped inner block3is placed in the groove7. The strip-shaped inner block3is made of soft material. A cover plate1is placed in slot A4. The cover plate1matches and fill up slot A4. The inner block2is in close contact with the strip-shaped inner block3. Both the inner block2and the strip-shaped inner block3are located within slot B5, and the combination of both matches and fill up the space in slot B5. The horizontal length and width of said slot A are larger or equal to the horizontal length and width of said slot B. The inner block2can be made of two half blocks, i.e., first half block8and second half block9. The first block8and second block9are in close contact with each other. The material for the first half block8may be the same or different with the material of the second half block9. The base6can includes two half bases, i.e., first half base10and second half base11.

One preferred embodiment of present inventions are shown inFIGS. 1-3. It includes one inner block2used for a full or twin size bed. An inner block2is placed in slot B5within the base6. A strip-shaped inner block is then placed into the groove7, which is formed between the inner block2and the slot B5. Finally a cover plate1fills up the slot A4within the base6. It is then ready for use. The strip-shaped inner block3is made of soft material. Therefore when someone is laying on his or her side, his or her shoulder and arm can be wholly or partially placed into groove7. It reduces the pressure against the shoulder and arm. When it is necessary to change the inner block2, one may simply take out cover plate1, take out the inner block102, place a new inner core block2into original position, and then put the cover plate1back in.

FIGS. 4-5show yet another preferred embodiment of the present inventions. When bed is a double, queen or king size, the mattress may include a first half base10and a second half base11, which together forms an integrated base. A first half inner block8and a second half inner block9are placed in slot B5formed by first half base10and second half base11. A strip-shaped core block3is placed in the groove7, which is the space between slot B5and first half inner block8and second half inner block9. A cover plate1is then set in slot A4, which is formed by first half base10and second half base11. The mattress is then ready for use. Because the strip-shaped inner block3is made of soft material when someone is laying on his or her side, his or her shoulder and arm can be wholly or partially placed into groove7. This reduces the pressure against the shoulder and arm. When a person is laying in another's arms, the holding person's arm can be placed underneath the other's body into the groove. It reduces the pressure on the holding person's arm and shoulder. Further it avoids the feeling or numbness and stiffness for the holding person. It minimize any discomfort that may occur. When it is necessary to change the first half inner block8and/or the second half inner block9, one can simply take out the cover plate1, take out first half block8and/or second half block9, put a new first half block8and/or second half block9into their respective original position, and then put the cover plate1back in.
