Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a mattress. Background Art

[0002] Existing mattresses include a cushion body with an internal support layer. This support layer houses a support bladder assembly, comprising pressure-adjustable support bladders arranged in a matrix, and an air platform connecting the bladders. The air platform not only inflates and deflates the bladders but also limits their displacement, ensuring a fixed relative position between them. Existing air platforms are typically located between the bases of the bladders, maintaining a constant position. This results in significant movement of the bladder tops due to inflation and deflation, making them susceptible to tilting and shifting due to external forces. This leads to unstable movement, impacting support effectiveness and user comfort. Utility Model Content

[0003] In order to address the shortcomings of the existing technology, the utility model provides a mattress, in which an air path platform is set in the middle of the supporting airbag, and the top and bottom of the supporting airbag can be independently extended and retracted relative to the air path platform, which effectively reduces the lifting and lowering amplitude of the top and bottom ends of the supporting airbag and improves the extension and retraction stability of the supporting airbag, and also limits the top and bottom of the supporting airbag through the upper through hole and the lower through hole, thereby improving the support reliability and comfort of use.

[0004] The utility model is achieved in the following way: a mattress, including a pad body, a support layer is provided in the pad body, the support layer includes an upper layer with an upper through hole, a lower layer with a lower through hole and a support bag group sandwiched between the upper layer and the lower layer, the support bag group includes an axially retractable columnar support air bag and an air path platform arranged in the middle of the support air bag, the air path platform is clamped by the upper layer and the lower layer so that the top and bottom of the support air bag can be telescopically inserted into the upper through hole and the lower through hole respectively. The air path platform is set in the middle of the support airbag, and upper and lower through holes for inserting the top and bottom of the support airbag are respectively opened on the upper layer and the lower layer. The top and bottom of the support airbag can be independently extended and retracted relative to the air path platform. The air path platform is clamped and positioned by the upper layer and the lower layer, which effectively reduces the lifting range of the top and bottom ends of the support airbag and improves the extension and retraction stability of the support airbag. The top and bottom of the support airbag are also limited by the upper and lower through holes to ensure that the support airbag can be vertically extended and retracted, thereby improving support reliability and comfort.

[0005] Preferably, the air path platform is flat and affixed to the middle section of the support airbag. It is clamped and secured by the bottom surface of the upper layer and the top surface of the lower layer, allowing the top and bottom sections of the support airbag to be telescopically suspended within the upper and lower through-holes, respectively. The air path platform is clamped and secured by the upper and lower layers, ensuring that the support bladder assembly remains centrally located within the support layer, and the softness and hardness of the support airbags can be adjusted by expanding and contracting the support airbags. The air path platform supports and positions the support airbags, allowing the top and bottom sections of the support airbags to be inserted into the upper and lower through-holes, respectively, and to be adjusted in size and length by inflation and deflation.

[0006] Preferably, the upper and lower layers are aligned and stacked so that the upper through-hole, the lower through-hole, and the supporting airbag are coaxially arranged. The supporting airbag is cylindrical, and the top and bottom of the supporting airbag can be concentrically inserted into the upper and lower through-holes, respectively. This prevents wear between the top and upper through-hole, and between the bottom and lower through-hole, due to eccentric placement, and ensures that the supporting airbag can be flexibly extended and adjusted.

[0007] Preferably, the diameter of the upper through hole is not less than the diameter of the top section of the support airbag, and the diameter of the lower through hole is not less than the diameter of the bottom section of the support airbag, ensuring that a movable gap is reserved between the top of the support airbag and the upper through hole, and between the bottom and the lower through hole to avoid friction damage.

[0008] Preferably, the upper layer is made of sponge and deforms synchronously with the expansion and contraction of the support airbags, allowing the top surface of the upper layer to rise and fall synchronously with the top surface of the support airbags while maintaining a flat surface. The upper layer compresses and deforms under pressure, ensuring that the vertical forces acting on the top surface of the support layer are effectively absorbed by the support airbags, improving the sensitivity of the cushion's hardness adjustment.

[0009] Preferably, the lower layer is made of sponge and can deform synchronously with the expansion and contraction of the support airbag. The lower layer is compressed to ensure that the bottom of the support airbag can contact the supporting surface below the cushion body, thereby ensuring that the top of the support airbag can effectively support the user above the cushion body.

[0010] Preferably, the support airbags are arranged in a matrix on the air platform, and an air channel is provided within the air platform, communicating with each of the support airbags to enable axial expansion and contraction through inflation and deflation. The air channel communicates with both the support airbags and a control box external to the cushion body, conveying airflow and ensuring that the support airbags can be inflated and deflated under the control of the control box, thereby ensuring free axial expansion and contraction.

[0011] Preferably, the upper through holes are arranged in a matrix pattern so that the top of each support airbag can be inserted into the corresponding upper through hole, and the lower through holes are arranged in a matrix pattern so that the bottom of each support airbag can be inserted into the corresponding lower through hole. The upper and lower through holes not only provide space for the support airbag to expand and contract, but also serve as guides and limiters for the expansion and contraction of the support airbag, ensuring that the support airbag always maintains an upright axis.

[0012] Preferably, the support airbag comprises at least four vertically stacked and interconnected unit cells. The vertical stacking of the unit cells allows their vertical deformation to accumulate, ensuring a good vertical deformation range for the support airbag, effectively increasing the hardness and softness adjustment range to meet the differentiated usage needs of users.

[0013] Preferably, the cushion body includes a massage layer disposed above the support layer. The support and massage layers are stacked and surrounded by a sponge edging. The massage layer provides massage stimulation to the user, thereby enhancing the cushion body's comfort. The sponge edging acts as a limiter and protector for the support and massage layers.

[0014] Preferably, the massage layer includes a group of massage bladders and a cover assembly that encloses the group of massage bladders. The group of massage bladders, when inflated and deflated, produces upward massage stimulation. The group of massage bladders expands and contracts vertically through inflation and deflation, thereby producing upward massage stimulation, thereby providing a massage service to the user. The cover assembly encloses, limits, and protects the group of massage bladders, ensuring that the group of massage bladders can exert massage stimulation upward.

[0015] The beneficial effects of the present invention are as follows: the air path platform is arranged in the middle of the support airbag, and upper and lower through holes for inserting the top and bottom of the support airbag are respectively opened on the upper layer and the lower layer. The top and bottom of the support airbag can be independently extended and retracted relative to the air path platform. The air path platform is clamped and positioned by the upper layer and the lower layer, which effectively reduces the lifting amplitude of the top and bottom ends of the support airbag and improves the extension and retraction stability of the support airbag. The top and bottom of the support airbag are also limited by the upper and lower through holes to ensure that the support airbag can be vertically extended and retracted, thereby improving the support reliability and comfort of use.

[0020] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0021] Example 1:

[0022] This embodiment provides a mattress.

[0023] like Figure 1 A mattress shown includes a cushion body, in which a support layer is provided. The support layer includes an upper layer 1 with an upper through hole 2, a lower layer 4 with a lower through hole 3, and a support bag group 5 sandwiched between the upper layer 1 and the lower layer 4. The support bag group 5 includes an axially retractable columnar support air bag 6 and an air path platform 7 arranged in the middle of the support air bag 6. The air path platform 7 is clamped by the upper layer 1 and the lower layer 4 so that the top and bottom of the support air bag 6 can be retractably inserted into the upper through hole 2 and the lower through hole 3, respectively. The air path platform 7 is set in the middle of the support airbag 6, and the upper through hole 2 and the lower through hole 3 for the top and bottom of the support airbag 6 to be inserted are respectively opened on the upper layer 1 and the lower layer 4. The top and bottom of the support airbag 6 can be independently extended and retracted relative to the air path platform 7. The air path platform 7 is clamped and positioned by the upper layer 1 and the lower layer 4, which effectively reduces the lifting amplitude of the top and bottom ends of the support airbag 6 and improves the extension and retraction stability of the support airbag 6. The top and bottom of the support airbag 6 are also limited by the upper through hole 2 and the lower through hole 3 to ensure that the support airbag 6 can be vertically extended and retracted, thereby improving the support reliability and comfort of use.

[0024] In this embodiment, the air path platform 7 is flat and fixed to the middle section of the support airbag 6. The air path platform 7 is clamped and fixed by the bottom surface of the upper layer 1 and the top surface of the lower layer 4, so that the top and bottom of the support airbag 6 are respectively telescopically suspended within the upper through hole 2 and the lower through hole 3. When installing the support layers, the support bag group 5 is first installed from top to bottom above the lower layer 4, with the bottom of the support airbag 6 inserted into the corresponding lower through hole 3. The bottom surface of the air path platform 7 is in contact with the top surface of the lower layer 4. Then, the upper layer 1 is installed from top to bottom onto the support bag group 5, with the upper through hole 2 on the upper layer 1 placed over the top of the corresponding support airbag 6, and the bottom surface of the upper layer 1 is in contact with the top surface of the air path platform 7.

[0025] After installation, the upper layer 1 and the lower layer 4 are stacked vertically and tightly clamp the air path platform 7. The support airbag 6 is fixedly connected to the air path platform 7 and suspended in position. The top and bottom of the support airbag 6 are respectively inserted into the corresponding upper through hole 2 and lower through hole 3.

[0026] In this embodiment, the support airbags 6 are arranged in a matrix on the air platform 7. Air channels are provided within the air platform 7, connecting each support airbag 6 to each other, enabling axial expansion and contraction of the support airbags 6 through inflation and deflation. During use, a control box is connected to one end of the air channel within the air platform 7 via an air tube, and the other end of the air channel is connected to each support airbag 6. The control box adjusts the air pressure within the support airbags 6 by inflating or deflation, allowing the support airbags 6 to adjust the cushion's hardness through vertical expansion and contraction.

[0027] In this embodiment, the upper layer 1 and the lower layer 4 are aligned and stacked so that the upper through hole 2, the lower through hole 3 and the support airbag 6 are coaxially arranged with each other, the diameter of the upper through hole 2 is not less than the diameter of the top section of the support airbag 6, and the diameter of the lower through hole 3 is not less than the diameter of the bottom section of the support airbag 6. The top section and the bottom section of the support airbag 6 are coaxially arranged with each other and can be suspended in the corresponding upper through hole 2 and the lower through hole 3 respectively, so that the top section and the bottom section of the support airbag 6 can be vertically telescopically adjusted under the guidance of the inner walls of the upper through hole 2 and the lower through hole 3 respectively.

[0028] In this embodiment, the upper through holes 2 are distributed in a matrix shape on the upper layer 1, and the lower through holes 3 are distributed in a matrix shape on the lower layer 4, so that the top and bottom of each support airbag 6 can be respectively inserted into the corresponding upper through hole 2 and lower through hole 3, thereby serving as a horizontal limit for each support airbag 6.

[0029] In this embodiment, both the upper layer 1 and the lower layer 4 are made of sponge. The upper layer 1 deforms synchronously with the retractable support airbags 6, so that the top surface of the upper layer 1 rises and falls synchronously with the top surface of the support airbags 6 and remains flat. The lower layer 4 also deforms synchronously with the retractable support airbags 6. The sponge-like upper and lower layers 1 and 4 have excellent deformability, allowing them to effectively transfer vertical forces acting on the cushion body to the support airbags 6 through their own deformation, ensuring that the support airbags 6 can precisely adjust the cushion body's softness and hardness, providing effective support for the user.

[0030] In this embodiment, the support airbag 6 includes at least four vertically stacked and interconnected unit bags 8 (such as Figure 2 In a preferred embodiment, the support airbag 6 includes six vertically stacked and interconnected unit bags 8, so that the top and bottom sections of the support airbag 6 each include three unit bags 8. This not only facilitates the insertion of the top and bottom sections of the support airbag 6 into the corresponding upper through-holes 2 and lower through-holes 3, but also ensures that the support airbag 6 can achieve a vertical expansion and contraction range that meets usage requirements through the vertical deformation of each unit bag 8, thereby precisely adjusting the softness and hardness of the cushion body.

[0031] Example 2:

[0032] Compared with the first embodiment, this embodiment provides another mattress.

[0033] like Figure 3 The mattress shown includes a massage layer 10 positioned above a support layer. The support and massage layers 10 are stacked and surrounded by a sponge edging 11. Both the support and massage layers 10 can achieve corresponding functions by adjusting air pressure. The support layer is used to adjust the overall hardness of the mattress, while the massage layer 10 can provide massage stimulation to the user while they lie down. The support and massage layers 10 work together to provide a comfortable sleeping experience. The sponge edging 11 acts as a horizontal limiter for the support and massage layers 10, ensuring their vertical alignment and protecting them. It also ensures a smooth sidewall and enhances the overall aesthetics of the mattress.

[0034] In this embodiment, the massage layer 10 comprises a group of massage bladders 9 and a cover assembly that encloses the group of massage bladders 9. The group of massage bladders 9 generates upward massage stimulation through inflation and deflation. The group of massage bladders 9 is vertically supported by the support bladder assembly 5 and expands and contracts vertically through inflation and deflation, generating upward massage stimulation. The cover assembly acts as a protective limiter for the group of massage bladders 9, ensuring that the massage bladders within the group of massage bladders 9 remain in an upright position.

[0035] The other structures and effects of the mattress described in this embodiment are consistent with those in the first embodiment and will not be described in detail.
