Abstract

The present invention relates to a mattress. Existing support bladders have poor extension and retraction stability. The mattress of the present invention comprises a mattress body, wherein a support layer is provided in the mattress body, and comprises an upper layer with upper through holes, a lower layer with lower through holes, and a support bladder group sandwiched between the upper layer and the lower layer, the support bladder group comprising columnar support bladders which can axially extend and retract and an air path platform which is arranged in middle portions of the support bladders, and the air path platform being clamped between the upper layer and the lower layer, such that the tops and bottoms of the support bladders are respectively extendably and retractably inserted into the upper through holes and the lower through holes. The air path platform is arranged in the middle portions of the support bladders, and the tops and the bottoms of the support bladders can independently extend and retract relative to the air path platform, thereby effectively reducing the lifting amplitudes at the top ends and the bottom ends of the support bladders, and thus improving the extension and retraction stability of the support bladders; moreover, the tops and the bottoms of the support bladders are limited by means of the upper through holes and the lower through holes, thereby improving the support reliability and the user comfort.

Description

A type of mattress Technical Field

[0001] This invention relates to the field of bedding, and more specifically to a mattress. Background Technology

[0002] Existing mattresses include a mattress body with an internal support layer. Within this support layer are support bladders, each bladder consisting of a matrix of adjustable-pressure air bladders and an air passage platform connecting them. This air passage platform both inflates and deflates the air bladders and restricts their displacement, ensuring a fixed relative position between them. However, existing air passage platforms are located at the bottom of the air bladders, keeping their bottom position constant. This results in significant height fluctuations at the top of the air bladders due to inflation and deflation, making them prone to tilting and shifting under external forces. This instability in the air bladder movement negatively impacts support and comfort. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a mattress in which an air passage platform is positioned in the middle of a support airbag. The top and bottom of the support airbag can extend and retract independently relative to the air passage platform. This effectively reduces the rise and fall of the top and bottom of the support airbag, improving its stability. Furthermore, the top and bottom of the support airbag are limited by upper and lower through-holes, enhancing support reliability and user comfort.

[0004] The present invention is achieved by means of the following: a mattress, comprising a mattress body, wherein a support layer is provided in the mattress body, the support layer comprising an upper layer with an upper through hole, a lower layer with a lower through hole, and a support bladder assembly sandwiched between the upper layer and the lower layer, the support bladder assembly comprising an axially retractable columnar support air bladder and an air passage platform disposed between the middle portions of the support air bladder, the air passage platform being sandwiched between the upper layer and the lower layer so that the top and bottom of the support air bladder are retractably inserted into the upper through hole and the lower through hole, respectively. The air passage platform is positioned in the middle of the support airbag, and upper and lower through holes are respectively opened on the upper and lower layers for the top and bottom of the support airbag to be inserted. The top and bottom of the support airbag can extend and retract independently relative to the air passage platform. The upper and lower layers clamp and position the air passage platform, effectively reducing the lifting range of the top and bottom of the support airbag and improving the stability of the support airbag's extension and retraction. The upper and lower through holes also limit the top and bottom of the support airbag, ensuring that the support airbag can extend and retract vertically, improving the reliability of the support and the comfort of use.

[0005] Preferably, the airway platform is flat and fixedly connected to the middle section of the support airbag. The airway platform is clamped and fixed by the bottom surface of the upper layer and the top surface of the lower layer, so that the top and bottom of the support airbag are retractably suspended in the upper and lower through holes, respectively. The airway platform is clamped and fixed by the upper and lower layers, ensuring that the support airbag assembly is always located in the middle of the support layer, and that the stiffness is adjusted by extending and retracting the support airbag. The airway platform supports and positions the support airbag, allowing the top and bottom of the support airbag to be inserted into the upper and lower through holes, respectively, and its expansion and contraction are adjusted by inflation and deflation.

[0006] Preferably, the upper and lower layers are stacked in alignment so that the upper through-hole, lower through-hole, and support airbag are coaxially arranged. The support airbag is cylindrical, and its top and bottom 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 arrangement, ensuring that the support 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 supporting airbag, and the diameter of the lower through hole is not less than the diameter of the bottom section of the supporting airbag, so as to ensure that there are movement gaps between the top and the upper through hole and between the bottom and the lower through hole of the supporting airbag to avoid friction damage.

[0008] Preferably, the upper layer is made of sponge material, and the upper layer can deform synchronously with the expanding and contracting support airbag, so that the top surface of the upper layer rises and falls synchronously with the top surface of the support airbag and remains flat. The upper layer can compress and deform under pressure, ensuring that the vertical force on the top surface of the support layer can be effectively borne by the support airbag, and improving the sensitivity of the pad's softness and hardness adjustment.

[0009] Preferably, the lower layer is made of sponge material, and the lower layer can deform synchronously with the expansion and contraction of the support airbag. The lower layer is compressed under force and ensures that the bottom of the support airbag can contact the supporting surface under the pad, thereby ensuring that the top of the support airbag can effectively support the user above the pad.

[0010] Preferably, the support airbags are arranged in a matrix on the air passage platform. The air passage platform has air passage channels communicating with each support airbag, allowing the support airbags to expand and contract axially through inflation and deflation. The air passage channels communicate with each support airbag and also connect to a control box external to the pad, serving to deliver airflow and ensuring that the support airbags can be inflated and deflated under the control of the control box, thereby ensuring that the support airbags can freely expand and contract axially.

[0011] Preferably, the upper through holes are arranged in a matrix, 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, 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 expansion and contraction of the support airbags, but also guide and limit the expansion and contraction of the support airbags, ensuring that the support airbags are always in a vertically oriented state.

[0012] Preferably, the support airbag comprises at least four vertically stacked and interconnected unit airbags. The vertical stacking of the unit airbags allows the vertical deformation of each unit airbag to accumulate and ensures that the support airbag has a good vertical deformation range, effectively improving the range of softness and hardness adjustment and meeting the diverse usage needs of users.

[0013] 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.

[0014] 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.

[0015] The beneficial effects of this invention are as follows: The air passage platform is set in the middle of the support airbag, and upper and lower through holes are respectively opened on the upper and lower layers for the top and bottom of the support airbag to be inserted. The top and bottom of the support airbag can extend and retract independently relative to the air passage platform. The upper and lower layers clamp and position the air passage platform, effectively reducing the lifting amplitude of the top and bottom of the support airbag and improving the stability of the support airbag's extension and retraction. The upper and lower through holes limit the top and bottom of the support airbag, ensuring that the support airbag can extend and retract vertically, improving the reliability of the support and the comfort of use.

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

[0021] Example 1:

[0022] This embodiment provides a mattress.

[0023] As shown in Figure 1, a mattress includes a mattress body with a support layer inside. 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 bladder assembly 5 sandwiched between the upper layer 1 and the lower layer 4. The support bladder assembly 5 includes an axially retractable columnar support airbag 6 and an air passage platform 7 disposed in the middle of the support airbag 6. The air passage platform 7 is sandwiched between the upper layer 1 and the lower layer 4 so that the top and bottom of the support airbag 6 can be retractably inserted into the upper through-hole 2 and the lower through-hole 3, respectively. The air passage platform 7 is set in the middle of the support airbag 6, and upper through holes 2 and lower through holes 3 are respectively opened on the upper layer 1 and lower layer 4 for the top and bottom of the support airbag 6 to be inserted. The top and bottom of the support airbag 6 can extend and retract independently relative to the air passage platform 7. The upper layer 1 and lower layer 4 clamp and position the air passage platform 7, effectively reducing the lifting amplitude of the top and bottom of the support airbag 6 and improving the extension and retraction stability of the support airbag 6. The upper through holes 2 and lower through holes 3 limit the top and bottom of the support airbag 6, ensuring that the support airbag 6 can extend and retract vertically, improving the reliability of the support and the comfort of use.

[0024] In this embodiment, the airway platform 7 is flat and fixed to the middle section of the support airbag 6. The airway 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 retractably suspended in the upper through hole 2 and the lower through hole 3, respectively. When installing the support layer, the support airbag assembly 5 is first installed from top to bottom above the lower layer 4, the bottom of the support airbag 6 is inserted into the corresponding lower through hole 3, and the bottom surface of the airway platform 7 abuts against the top surface of the lower layer 4. Then, the upper layer 1 is installed from top to bottom onto the support airbag assembly 5, the upper through hole 2 on the upper layer 1 is fitted onto the top of the corresponding support airbag 6, and the bottom surface of the upper layer 1 abuts against the top surface of the airway platform 7.

[0025] After installation, the upper layer 1 and the lower layer 4 are vertically stacked and tightly clamp the air passage platform 7. The support airbag 6 is fixed to the air passage 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 airway platform 7. The airway platform 7 has airway channels communicating with each support airbag 6, so that the support airbags 6 can achieve axial expansion and contraction through inflation and deflation. In use, the control box is connected to one end of the airway channel in the airway platform 7 through an air tube, and the other end of the airway channel is connected to each support airbag 6. The control box adjusts the air pressure inside the support airbags 6 by performing inflation or deflation operations, so that the support airbags 6 can adjust the softness and hardness of the pad by 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 supporting airbag 6 are coaxially arranged. The diameter of the upper through hole 2 is not less than the diameter of the top section of the supporting airbag 6, and the diameter of the lower through hole 3 is not less than the diameter of the bottom section of the supporting airbag 6. The top section and the bottom section of the supporting airbag 6 are coaxially arranged and can be suspended in the corresponding upper through hole 2 and lower through hole 3, so that the top section and the bottom section of the supporting airbag 6 can be vertically extended and retracted under the guidance of the inner wall of the upper through hole 2 and the inner wall of the lower through hole 3, respectively.

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

[0029] In this embodiment, both the upper layer 1 and the lower layer 4 are made of sponge material. The upper layer 1 can deform synchronously with the expanding and contracting support airbag 6, so that the top surface of the upper layer 1 rises and falls synchronously with the top surface of the support airbag 6 and remains flat. The lower layer 4 can deform synchronously with the expanding and contracting support airbag 6. The sponge material of the upper layer 1 and the lower layer 4 has good deformation performance, which allows the upper layer 1 and the lower layer 4 to ensure that the vertical force on the pad is effectively transmitted to the support airbag 6 through their own deformation. This ensures that the support airbag 6 can accurately adjust the softness and hardness of the pad and provide effective support for the user.

[0030] In this embodiment, the support airbag 6 includes at least four vertically stacked and interconnected unit airbags 8 (as shown in Figure 2). Preferably, the support airbag 6 includes six vertically stacked and interconnected unit airbags 8, such that both the top and bottom sections of the support airbag 6 include three unit airbags 8. This facilitates the insertion of the corresponding upper through-hole 2 and lower through-hole 3 into the top and bottom sections of the support airbag 6, and also ensures that the support airbag 6 can achieve the required vertical expansion and contraction range through the vertical deformation of each unit airbag 8, thereby precisely adjusting the hardness of the pad.

[0031] Example 2:

[0032] Compared to Example 1, this example provides another type of mattress.

[0033] As shown in Figure 3, a mattress 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 11. 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 11 acts as a horizontal limiter for the support layer and massage layer 10, ensuring their vertical alignment, protecting both the massage layer 10 and the support layer, and ensuring the mattress sidewalls are flat, thus improving the overall aesthetics.

[0034] In this embodiment, the massage layer 10 includes a massage bag assembly 9 and an outer casing assembly that encloses the massage bag assembly 9. The massage bag assembly 9 generates upward-transmitted massage stimulation through inflation and deflation. The massage bag assembly 9 is vertically supported by the support bag assembly 5 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 9, ensuring that the massage airbags inside the massage bag assembly 9 are always in a vertical position.

[0035] 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.
