Air bag, and air cushion and mattress using same

Abstract

The present invention relates to an air bag, and an air cushion and a mattress using same. The vertical deformation travel of unit bags of existing air bags is relatively small, resulting in troubles in processing. The present invention comprises a bag body, which comprises at least one unit bag, wherein the unit bag comprises two substrates which are stacked and bonded at the periphery, and annular ripples are arranged on the substrates. The bag body can be switched between a contracted state in which the annular ripples are folded and a ridge state in which the annular ripples are stretched, so as to increase the vertical deformation of the bag body. The substrates with the annular ripples are provided such that the air bag obtains greater vertical deformation by means of the annular ripples, such that the number of unit bags of a single air bag is reduced, the production efficiency is improved and processing is facilitated, and the processing difficulty is reduced by reducing the number of bonding times, thus reducing the number of scrapped air bags and improving the use experience.

Description

Airbag and air cushion and mattress using the same Technical Field

[0001] The present invention relates to the field of bedding, in particular to an air bag and an air cushion and a mattress using the same. Background Art

[0002] Existing mattresses include a main body and a cover that wraps the main body. The main body is equipped with airbags and a control box that regulates the air pressure within the airbags. The control box adjusts the hardness of the main body by controlling the air pressure within the airbags. Existing massage airbags consist of multiple vertically stacked unit bags, each formed by gluing two flat substrates together. Because the substrates are planar, the vertical deformation amplitude of each unit bag is small, requiring a large number of unit bags to achieve sufficient vertical deformation travel. This increases the difficulty of manufacturing the airbags due to the large number of substrates that need to be glued together, thus affecting production efficiency. Inaccurate gluing can also easily lead to the airbag being scrapped, affecting the user experience. Summary of the Invention

[0003] In order to address the deficiencies of the prior art, the present invention provides an airbag and an air cushion and mattress using the same, and is provided with a base sheet with annular corrugations. The number of unit capsules is reduced by increasing the vertical deformation stroke of the unit capsules, which not only facilitates processing and improves production efficiency, but also reduces processing difficulty by reducing the number of adhesions, thereby reducing the number of scrapped airbags and improving the user experience.

[0004] The present invention is achieved through the following method: an airbag comprising a body, the body comprising at least one unit cell, each comprising two substrates adhered to each other by overlapping edges, the substrates being provided with annular corrugations. The airbag can switch between a contracted state (in which the annular corrugations are folded) and an inflated state (in which the annular corrugations are extended) to increase the vertical deformation amplitude of the airbag. The provision of the substrate with annular corrugations allows the airbag to achieve a greater vertical deformation amplitude through the annular corrugations, thereby reducing the number of unit cells in a single airbag. This not only facilitates processing and improves production efficiency, but also reduces processing difficulty by reducing the number of adhesions, thereby reducing the number of airbag scraps and improving the user experience.

[0005] Preferably, a functional area is provided in the middle of the base sheet, and the annular corrugation surrounds the functional area. The annular corrugation surrounds the functional area and is coaxial with each other, ensuring that each circumferential segment of the annular corrugation has the same vertical deformation amplitude, thereby ensuring that the functional area can be smoothly raised and lowered along the vertical axis in a horizontal position, and further ensuring that the airbag can expand and contract along the vertical circumferential direction, providing effective support for a lying user.

[0006] Preferably, the annular corrugations are at least two layers and are connected in sequence along the radial direction of the substrate with the inner and outer edges of adjacent annular corrugations being connected and presenting a regular continuous wave shape. This can reduce the thickness of the annular corrugations when they are folded and contracted by increasing the number of annular corrugations, and can also reduce the number of unit capsules by increasing the vertical deformation amplitude of a single substrate.

[0007] Preferably, the cross-section of the annular corrugation is wavy, and the wave shape is a horizontal S-shape, which not only facilitates the adjacent annular corrugations to form a regular continuous wave shape after being connected, but also ensures that the annular corrugation can switch freely between the folded state and the unfolded state, ensuring that the airbag can accurately expand and contract along the vertical axis.

[0008] Preferably, the functional area of ​​the base sheet located on the top surface of the bladder body forms a support and resistance surface. The functional area in the middle of the bladder body top surface forms a support and resistance surface that can transmit the supporting force upward. The support and resistance surface is always perpendicular to the axis of the airbag, ensuring that the support and resistance surface can stably support the user and achieve the purpose of adjustable mattress softness and hardness.

[0009] Preferably, an air port communicating with the outside is provided at the functional area of ​​the base plate on the bottom surface of the airbag body, and the airbag is connected to an external control box via the air port so that the air pressure inside the airbag can be adjusted.

[0010] Preferably, there are at least two unit capsules stacked concentrically in a vertical direction. By providing a plurality of vertically stacked unit capsules, the vertical deformation strokes of the unit capsules are superimposed, thereby enabling the airbag to obtain a preset vertical deformation height after inflation.

[0011] Preferably, adjacent unit capsules have through-holes in the middle of their corresponding substrate functional areas, and the adjacent unit capsules are bonded together by attaching the perimeters of the through-holes to provide interconnection. Adjacent substrates can be connected not only through vertically aligned through-holes but also through bonding the perimeters of the through-holes to achieve a sealed connection between adjacent unit capsules.

[0012] An air cushion using the airbags includes a cushion body, with the airbags arranged on the top surface of the cushion body. The cushion body is used to position the airbags and facilitate air path connection between the airbags, ensuring that the air pressure of the airbags on the cushion body can be uniformly controlled and adjusted.

[0013] Preferably, the airbags are connected in series via air pipes provided in the cushion body, so that the airbags can achieve synchronous deformation under the control of the control box, effectively simplifying the pipeline structure and facilitating control.

[0014] Preferably, the airbags are arranged linearly and equidistantly, and the long strip air cushion is provided with airbags arranged linearly and equidistantly, and the width of the air cushion is reduced to facilitate arrangement and matching according to usage requirements.

[0015] Preferably, the airbags are arranged in a matrix shape, and the rectangular air cushion is provided with airbags arranged in a matrix shape, which can effectively cover a larger area and is convenient for laying and use.

[0016] A mattress using the aforementioned airbags comprises a main body and an outer cover enclosing the main body. The main body comprises a comfort layer, a functional layer, and a support layer arranged sequentially from top to bottom. The functional layer comprises an air cushion containing the airbags and a sponge pad with perforations. The airbags are retractably inserted into the perforations. A control box for regulating the air pressure within the airbags is provided at the rear of the support layer. The sponge pad is stacked on the air cushion from top to bottom, so that the airbags are inserted into the corresponding perforations from bottom to top. The perforations not only guide the airbags vertically, preventing them from tilting during inflation and deflation, but also effectively fill the gaps between adjacent airbags, ensuring a flat top surface on the functional layer. This facilitates the smooth installation of the comfort layer, thereby enhancing sleeping comfort.

[0017] The beneficial effects of the present invention are as follows: a substrate with annular corrugations is provided, and the airbag obtains a larger vertical deformation amplitude through the annular corrugations, thereby reducing the number of unit bags in a single airbag, which not only facilitates processing and improves production efficiency, but also reduces processing difficulty by reducing the number of adhesions, thereby reducing the number of scrapped airbags and improving the user experience.

Modes for Carrying Out the Invention

[0025] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1:

[0027] This embodiment provides an airbag.

[0028] As shown in Figures 1 and 2, an airbag comprises a body comprising at least one unit cell 1, each comprising two substrates 2 adhered to each other by a stacked periphery. The substrates 2 are provided with annular corrugations 3, which allow the body to switch between a contracted state (in which the annular corrugations 3 are folded) and an expanded state (in which the annular corrugations 3 are extended) to increase the vertical deformation amplitude of the body. The annular corrugations 3 are provided on the periphery of the substrate 2, allowing the body to switch between a folded state and an expanded state. This increases the vertical deformation amplitude of the body by increasing the vertical deformation amplitude of the substrate 2. This reduces the number of unit cells 1 in a single airbag 8, facilitating processing and improving production efficiency. Furthermore, the number of adhesions is reduced, thereby reducing the number of scrapped airbags 8 and improving the user experience.

[0029] In this embodiment, a functional area is provided in the middle of the substrate 2, and the annular corrugation 3 is arranged around the functional area. The annular corrugation 3 is arranged around the periphery of the substrate 2 so that the two are coaxially arranged. During processing and production, the substrates 2 are vertically aligned and stacked and hot-melt-bonded by corresponding peripheries to form unit capsules 1. Adjacent unit capsules 1 are vertically stacked and hot-melt-bonded by corresponding through-holes 6. This can not only improve the adhesion sealing and reliability by increasing the area of ​​the adhesion area, but also realize the connection between adjacent unit capsules 1 through the aligned through-holes 6, ensuring that the air pressure of each unit capsule 1 can be adjusted synchronously, and realizing the accumulation of vertical deformation stroke by controlling the synchronous deformation of each unit capsule 1, thereby ensuring that the vertical deformation stroke of the airbag 8 meets the use requirements.

[0030] In this embodiment, the cross-section of the annular corrugation 3 is wavy, the annular corrugation 3 is at least two layers and is arranged in radial expansion sequence along the substrate 2, the inner edge of the built-in annular corrugation 3 is connected to the periphery of the functional area, the outer edge of the built-in annular corrugation 3 is connected to the inner edge of the external annular corrugation 3, the outer edge of the external annular corrugation 3 is connected to the outer edge of the substrate, and the outer edge of the substrate is flatly arranged, which facilitates the adjacent substrates 2 to be bonded by hot-melt bonding through the outer edge.

[0031] In this embodiment, the functional areas in the middle of each substrate 2 have differentiated functions. Specifically, the functional area on the bottom surface of the bladder is provided with an air vent 5 that communicates with the outside world. This vent 5 connects to an external control box 14, regulating and controlling the air pressure within the bladder. The functional area on the top surface of the bladder forms a support and resistance surface 4, which rises horizontally when the bladder is inflated. Adjusting the air pressure allows for softness and hardness adjustments, thereby providing support and elevation for a recumbent user. The functional area on the middle section of the bladder is provided with a through hole 6, which facilitates the bonding and connection of adjacent unit bladders 1 and ensures connectivity between adjacent unit bladders 1.

[0032] In this embodiment, at least two, preferably three, unit bladders 1 are stacked concentrically vertically. This ensures that the vertical deformation of the bladder body meets operational requirements while also facilitating production by reducing the number of unit bladders 1. The bladder body comprises six substrates 2, each of which has an annular corrugation 3 capable of switching to an expanded state and achieving a vertical deformation stroke. This not only meets operational requirements by accumulating the vertical deformation strokes of each substrate 2 during inflation of the airbag 8, but also reduces the thickness of the airbag 8 by folding the annular corrugation 3 during deflation, effectively eliminating any foreign body sensation.

[0033] It can be understood that the number of annular corrugations 3 on a single substrate 2 can be set according to usage requirements and arranged radially in sequence, which should be regarded as specific implementation methods of this embodiment.

[0034] It can be understood that the number of unit bags 1 stacked in the air bag 8 can be increased or decreased as needed to meet the use requirements, and all of them should be regarded as specific implementation methods of this embodiment.

[0035] Example 2:

[0036] Compared with the first embodiment, this embodiment provides an air cushion.

[0037] As shown in Figure 4, a massage cushion consists of a cushion body 7, on which the airbags 8 are arranged. The cushion body 7 is used to position and connect the airbags 8 to ensure that the relative positions of adjacent airbags 8 are fixed. The cushion body 7 can also control the air pressure of each airbag 8 to ensure that the airbags 8 form an upward supporting force through inflation and deflation, and the lying comfort is improved by adjusting the softness and hardness of the air cushion 11.

[0038] In this embodiment, the airbags 8 are connected in series via an air tube disposed within the cushion body 7. One end of the air tube is connected to an external control box 14, and the other end is connected in series with each airbag 8 on the same cushion body 7, allowing the air pressure within the airbags 8 to be adjusted synchronously. Furthermore, the airbags 8 on the same cushion body 7 can be arranged in multiple groups as needed and connected in series via corresponding air tubes, allowing each group of airbags 8 to operate independently and coordinate with each other, thereby enhancing the massage experience. This should also be considered a specific implementation of this embodiment.

[0039] In this embodiment, the airbags 8 are arranged linearly and equidistantly or in a matrix shape, and the user can set it according to needs, which should also be regarded as a specific implementation of this embodiment.

[0040] The structure and effect of the airbag described in this embodiment are consistent with those in the first embodiment and will not be described in detail.

[0041] Example 3:

[0042] Compared with the first embodiment, this embodiment provides a mattress.

[0043] As shown in Figures 5 and 6, a mattress comprises a main body and an outer cover enclosing the main body. The main body includes, arranged in order from top to bottom, a comfort layer 9, a functional layer, and a support layer 10. The functional layer comprises an air cushion 11 containing the airbag 8 and a sponge pad 13 with perforations 12. The airbag 8 is retractably inserted into the perforations 12. A control box 14 for regulating the air pressure within the airbag 8 is provided at the rear of the support layer 10. The functional layer is arranged between the comfort layer 9 and the support layer. The support layer not only provides vertical support for the functional layer, ensuring that the vertical travel of the inflated airbag 8 is converted into a supporting force for the user, but also utilizes the deformation of the comfort layer 9 to eliminate the foreign body sensation caused by the inflation of the airbag 8, thereby enhancing the user's sleeping experience.

[0044] In this embodiment, the sponge pad 13 is stacked on the air cushion 11 from top to bottom, so that the airbag 8 is inserted into the corresponding perforation 12 from bottom to top. The perforation 12 not only guides the airbag 8 vertically to prevent the airbag 8 from tilting when it is inflated and deflated, but also effectively fills the gap between adjacent airbags 8, ensuring that the top surface of the functional layer remains flat, facilitating the flat laying of the comfort layer 9, and thereby improving lying comfort.

[0045] The structure and effect of the airbag described in this embodiment are consistent with those in the first embodiment and will not be described in detail.
