Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a mattress. Background Technology

[0002] Existing mattresses include a mattress body with an internal pleated assembly. This assembly consists of matrix-arranged, pressure-adjustable airbags that rise and fall vertically by inflating and deflating to achieve the desired function and meet the user's needs. However, airbags located at the edges of the pleated assembly may tilt under external forces, causing the mattress edges to deform and affecting comfort.

[0003] In addition, because there is a gap between adjacent airbags for them to extend and retract, the airbags may tilt due to external forces when they are raised and lowered vertically. This causes the adjacent airbags to interfere with each other and cannot extend and retract normally. This can easily lead to damage due to friction between adjacent airbags, affecting their service life, and can also reduce the comfort of use because the airbags cannot extend and retract in the preset direction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mattress in which an outer frame is placed over the support bladder assembly. The outer frame serves to limit and shape the periphery of the support bladder assembly, preventing deformation due to stress and ensuring that the support bladder assembly can expand and contract in a predetermined direction, thus guaranteeing comfort and improving the user experience.

[0005] This utility model is achieved through the following method: A mattress includes a mattress body, within which a support layer is provided. The support layer includes a support bladder assembly and an outer frame with an internal assembly cavity. The support bladder assembly is inserted into the assembly cavity and positioned by the outer frame. The outer frame is placed over the support bladder assembly, which limits and shapes the periphery of the support bladder assembly, guiding it to expand and contract in a predetermined direction and providing effective support for the user. This prevents the support bladder assembly from deforming under stress, ensuring comfort and improving the user experience.

[0006] Preferably, the support bladder assembly includes support airbags arranged in a matrix. The sidewall of the assembly cavity is provided with an arc-shaped groove. The support airbags located at the edge of the support bladder assembly are inserted into the assembly cavity and locked into the corresponding grooves. The arc-shaped grooves on the sidewall of the assembly cavity can be fitted onto the corresponding support airbags, so that the support airbags can achieve vertical expansion and contraction under the guidance of the groove wall. This not only prevents the support airbags from tilting and ensures that the support airbags can generate a vertically upward supporting force, but also limits the support airbags located at the edge of the support bladder assembly, preventing the support airbags from tilting.

[0007] Preferably, the sidewall of the assembly cavity extends inward to form an anchoring portion, which is embedded between four adjacent support airbags in the corresponding section of the side edge of the support airbag assembly, so that the sidewall of the support airbag assembly fits tightly against the sidewall of the assembly cavity. The anchoring portion can be locked between four adjacent support airbags arranged in a square, ensuring that the groove wall fits tightly against the corresponding support airbag, thereby improving the reliability of limiting the support airbag.

[0008] Preferably, the anchoring part is cross-shaped, and the periphery of the anchoring part is provided with an arc-shaped groove that fits against the side wall of the corresponding support airbag. The side of the anchoring part is provided with four symmetrically placed arc-shaped grooves. The arc-shaped grooves can fit against the side wall of the corresponding support airbag, so that the anchoring part can completely fill the gap between the four support airbags, ensuring that the anchoring part is firmly clamped by the four support airbags, effectively improving the anchoring reliability, and preventing the inner side wall of the outer frame from separating from the outer side wall of the support airbag assembly, which would affect the limiting effect.

[0009] Preferably, the anchoring parts are equidistantly distributed along the long sidewall of the assembly cavity to ensure that the long sidewall of the assembly cavity can fit tightly with the long sidewall of the support bladder assembly, thereby improving the limiting effect on the long sidewall of the support bladder assembly.

[0010] Preferably, the assembly cavity is vertically and continuously formed within the outer frame. The support bladder assembly is vertically inserted into the assembly cavity, and the vertically continuous assembly cavity ensures that the support bladder assembly can freely extend and retract vertically, and also ensures that the outer frame can act as a stop and limit against the outer wall of the support bladder assembly, ensuring that the support airbag located at the edge of the support bladder assembly always maintains a vertical posture.

[0011] Preferably, the support layer includes a limiting block disposed within the assembly cavity and filling the gaps between adjacent support airbags. The limiting block has limiting holes arranged in a matrix. Each support airbag is inserted into a corresponding limiting hole and radially limited, so that the limiting block and the support airbag assembly cooperate to fill the assembly cavity. The limiting block is fitted onto the corresponding support airbag through the limiting holes, effectively filling the gaps between adjacent support airbags and limiting the position of the support airbag located in the middle of the support airbag assembly, preventing the support airbag from shifting or tipping over.

[0012] Preferably, the sidewall of the limiting block matches and fits against the sidewall of the assembly cavity, wrapping around the support airbag located at the edge of the support airbag assembly, thereby reducing the radial offset space of the support airbag. The limiting block can completely fill the space between the support airbag and the sidewall of the assembly cavity, which not only limits each support airbag, ensuring that each support airbag can always maintain an upright posture, but also ensures that the limiting block can be smoothly inserted into the assembly cavity, facilitating assembly.

[0013] Preferably, the diameter of the limiting hole is not less than the diameter of the supporting airbag, so that the supporting airbag can axially expand and contract within the limiting hole by inflation and deflation. An assembly gap is reserved between the inner wall of the limiting hole and the outer wall of the corresponding supporting airbag to facilitate the vertical expansion and contraction of the supporting airbag within the limiting hole and to prevent wear between the two.

[0014] Preferably, the limiting block includes multiple independently detachable unit blocks. The unit blocks are processed independently and installed into the assembly cavity respectively. The unit blocks are assembled to form a limiting block that completely fills the space between the assembly cavity and the support bladder group, which is convenient for both processing and assembly.

[0015] Preferably, both the outer frame and the limiting block are made of sponge material, with the outer frame having a higher hardness than the limiting block. The outer frame and the limiting block are independently manufactured and meet their respective usage requirements. The outer frame not only limits the support airbag but also uses its structural strength to support users sitting on the edge of the cushion, ensuring that the cushion's edge contour does not sag or deform irreversibly due to the user's weight. The limiting block not only limits the support airbag but also needs to deform synchronously with it, ensuring that the support airbag assembly can effectively adjust the cushion's firmness to meet users' diverse support needs.

[0016] Preferably, the pad includes a massage layer disposed above the support layer, the support layer and the massage layer being stacked and surrounded by a sponge edging. The massage layer provides massage stimulation to the user, thereby improving the comfort of using the pad. The sponge edging serves to limit and protect the support layer and the massage layer.

[0017] Preferably, the massage layer includes a massage capsule assembly and an outer sleeve assembly that encloses the massage capsule assembly. The massage capsule assembly generates upward-transmitted massage stimulation through inflation and deflation. The massage capsule assembly expands and contracts vertically through inflation and deflation, thereby generating upward-transmitted massage stimulation to provide a massage service to the user. The outer sleeve assembly encloses, limits, and protects the massage capsule assembly, ensuring that the massage capsule assembly can apply upward massage stimulation.

[0018] The beneficial effects of this utility model are as follows: An outer frame is placed over the support bladder assembly, which serves to limit and shape the periphery of the support bladder assembly, guide the support bladder assembly to extend and retract in a preset direction, provide effective support for the user, prevent the support bladder assembly from deforming due to force, ensure comfort, and improve the user experience.

[0025] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] This embodiment provides a mattress.

[0028] like Figure 1 The mattress shown includes a mattress body with a support layer inside. The support layer includes a support bladder assembly 1 and an outer frame 2 with an internal assembly cavity 3. The support bladder assembly 1 is inserted into the assembly cavity 3 and positioned by the outer frame 2. The outer frame 2 is placed over the support bladder assembly 1, which limits and shapes the periphery of the support bladder assembly 1, guiding it to expand and contract in a predetermined direction and providing effective support for the user. This prevents the support bladder assembly 1 from deforming under stress, ensuring comfort and improving the user experience.

[0029] In this embodiment, the support bladder assembly 1 includes support airbags 4 arranged in a matrix. The sidewall of the assembly cavity 3 is provided with arc-shaped grooves 5. The support airbags 4 located at the edge of the support bladder assembly 1 are inserted into the assembly cavity 3 and locked in the corresponding grooves 5. The inner wall of the assembly cavity 3 is covered with arc-shaped grooves 5, which not only ensures that the vertical projection of the support airbags 4 can fall completely into the assembly cavity 3, ensuring that the support airbags 4 can be smoothly inserted into the assembly cavity 3, but also effectively reduces the gap between the sidewall of the assembly cavity 3 and the sidewall of the support bladder assembly 1, effectively improving the reliability of the limiting.

[0030] In this embodiment, the sidewall of the assembly cavity 3 extends inward to form an anchoring portion 6. The anchoring portion 6 is embedded between four adjacent supporting airbags 4 in the corresponding section of the side edge of the supporting airbag assembly 1, so that the sidewall of the supporting airbag assembly 1 is tightly fitted with the sidewall of the assembly cavity 3. The anchoring portion 6 is cross-shaped, and the periphery of the anchoring portion 6 is provided with an arc-shaped groove 7 that fits against the sidewall of the corresponding supporting airbag 4. The assembly cavity 3 is vertically and continuously opened in the outer frame 2, and the contours of each horizontal section of the assembly cavity 3 are the same, which facilitates both mass production and assembly with the supporting airbag assembly 1.

[0031] In this embodiment, during installation, the outer frame 2 is fitted onto the support bladder assembly 1, and the anchoring part 6 is embedded between the four corresponding support airbags 4. After installation, the support bladder assembly 1 is vertically inserted into the assembly cavity 3, ensuring that the support airbags 4 can freely extend and retract vertically. The support airbags 4 located around the periphery of the support bladder assembly 1 are matched and fitted with the grooves 5 set on the inner sidewall of the assembly cavity 3, which play a horizontal limiting role for the support airbags 4 and prevent the support airbags 4 from shifting or tilting. The anchoring part 6 is matched and fitted with the sidewall of the corresponding support airbag 4 through the arc groove 7, ensuring that the anchoring part 6 is horizontally clamped and positioned, thereby ensuring that the inner sidewall of the assembly cavity 3 can be tightly fitted with the outer sidewall of the support bladder assembly 1.

[0032] In this embodiment, the anchoring parts 6 are equidistantly distributed along the long sidewall of the assembly cavity 3 (e.g., Figure 2 As shown, this design ensures that the long sidewall of the assembly cavity 3 fits tightly against the long sidewall of the support bladder assembly 1, and simplifies the structure by not setting the anchoring part 6 on the short sidewall of the assembly cavity 3, thus facilitating assembly.

[0033] Example 2:

[0034] Compared to Example 1, this example provides another type of mattress.

[0035] like Figure 3 The mattress shown includes a support layer comprising a limiting block 8 disposed within an assembly cavity 3 and filling the gaps between adjacent support airbags 4. The limiting block 8 has limiting holes 9 arranged in a matrix. Each support airbag 4 is inserted into a corresponding limiting hole 9 and radially limited, so that the limiting block 8 cooperates with the support airbag assembly 1 to fill the assembly cavity 3. The limiting block 8 with limiting holes 9 is disposed within the assembly cavity 3, and its vertical projection falls completely within the assembly cavity 3 and is completely offset from the vertical projection of the support airbag 4. This serves to limit the position of the support airbag 4 located in the middle of the support airbag assembly 1, preventing the support airbag 4 from shifting or tipping over.

[0036] During installation, the limiting block 8 is embedded in the assembly cavity 3 and fitted onto the corresponding support airbag 4 through the limiting hole 9. After installation, the side wall of the limiting block 8 matches and fits against the side wall of the assembly cavity 3, wrapping around the support airbag 4 located at the edge of the support airbag assembly 1. The limiting block 8 can completely fill the gap between the side wall of the assembly cavity 3 and the support airbag 4 to reduce the radial offset space of the support airbag 4, ensuring that the support airbag 4 can achieve vertical expansion and contraction under the guidance of the limiting hole 9, thereby providing comfortable support for the user.

[0037] In this embodiment, the diameter of the limiting hole 9 is not less than the diameter of the supporting airbag 4, so that the supporting airbag 4 can axially expand and contract within the limiting hole 9 by inflation and deflation. The inner cavity of the limiting hole 9 is cylindrical, and the vertical projection of the supporting airbag 4 is circular. The diameter of the limiting hole 9 is not less than the diameter of the supporting airbag 4. An assembly gap is reserved between the inner wall of the limiting hole 9 and the corresponding outer wall of the supporting airbag 4 to facilitate the vertical expansion and contraction of the supporting airbag 4 within the limiting hole 9 and to prevent wear between the two.

[0038] In this embodiment, the periphery of the limiting block 8 can match and fit against the inner wall of the assembly cavity 3 and completely wrap the support airbag 4 located at the edge of the support airbag group 1, ensuring that the outer frame 2 and the limiting block 8 can horizontally limit all the support airbags 4 on the support airbag group 1 after they are assembled, thereby ensuring that the support airbag 4 can perform vertical extension and retraction.

[0039] In this embodiment, both the outer frame 2 and the limiting block 8 are made of sponge material, with the outer frame 2 having a higher hardness than the limiting block 8. Besides providing horizontal restraint for the supporting airbag 4, the outer frame 2 also provides vertical support, ensuring good deformation resistance around the pad. The limiting block 8 is relatively soft, providing both horizontal restraint for the supporting airbag 4 and vertical expansion and contraction synchronously with it. This ensures that the supporting airbag 4 can adjust the pad's hardness through inflation and deflation, improving adjustment sensitivity and meeting the diverse usage needs of users.

[0040] Understandably, the limiting block 8 includes multiple independently detachable unit blocks 12 (such as...). Figure 4 As shown, each unit block 12 is processed independently and then assembled into the limiting block 8 after being inserted into the assembly cavity 3. This not only facilitates processing but also effectively reduces assembly difficulty and improves assembly efficiency. It should also be regarded as a specific implementation method of this embodiment.

[0041] The other structures and effects of the mattress described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0042] Example 3:

[0043] Compared to Embodiment 1 or 2, this embodiment provides an alternative mattress structure.

[0044] like Figure 5The mattress shown includes a massage layer 10 positioned above a support layer. The support layer and massage layer 10 are stacked and surrounded by a foam border 13. Both the support layer and massage layer 10 can achieve corresponding functions by adjusting air pressure. The support layer is used to adjust the overall firmness of the mattress, while the massage layer 10 provides massage stimulation to the user lying down. The support layer and massage layer 10 work together to provide a comfortable lying experience for the user. The foam border 13 acts as a horizontal limiter for the support layer and massage layer 10, ensuring that the support layer and massage layer 10 are vertically aligned, protecting both the massage layer 10 and the support layer, and ensuring that the mattress sidewalls are flat, thus improving the overall aesthetics.

[0045] In this embodiment, the massage layer 10 includes a massage bag assembly 11 and an outer casing assembly that encloses the massage bag assembly 11. The massage bag assembly 11 generates upward-transmitted massage stimulation through inflation and deflation. The massage bag assembly 11 is vertically supported by the support bag assembly 1 and achieves vertical expansion and contraction through inflation and deflation, thereby generating upward-transmitted massage stimulation. The outer casing assembly provides protection and limitation for the massage bag assembly 11, ensuring that the massage airbags inside the massage bag assembly 11 are always in a vertical position.

[0046] The other structures and effects of the mattress described in this embodiment are the same as those in Embodiment 1 or 2, and will not be repeated here.
