Description

Technical Field

[0001] This utility model relates to the field of mattresses, and more particularly to a mattress with adjustable firmness and temperature. Background Technology

[0002] As people's living standards improve, the comfort of mattresses is receiving increasing attention. In order to meet the needs of different users, mattress manufacturers have also begun to develop different new products. Among these needs, firmness is usually what users care about most. For example, some users prefer firm mattresses, while others prefer soft mattresses.

[0003] Double-sided adjustable mattresses, also known as dual-sided sleeping mattresses, are now available on the market. These mattresses typically have a firmer top and a softer bottom, allowing users to flip the mattress to their liking. While this design solves the problem of adjustable firmness, it requires flipping the entire mattress for adjustment. Because of the spring support layers, the mattress is quite heavy, requiring considerable effort to flip, which is particularly inconvenient for female users. Some users even never flip the mattress after installation.

[0004] In response to this situation, removable mattresses have begun to appear on the market. These mattresses have layers of varying firmness inside, allowing users to adjust the order of these layers according to their needs. For example, users who prefer a firmer feel can place the firmer layers closer to the top, while those who prefer a softer feel can place the softer layers, such as foam or latex, closer to the top. This removable structure eliminates the need to flip the entire mattress, making it more convenient.

[0005] However, while such removable mattresses may have drawbacks during long-term use and testing, especially the softer foam and latex layers, these layers are prone to shifting or moving when the user turns over or applies other forces, resulting in a poor user experience. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mattress with adjustable firmness and temperature, which allows users to conveniently and effortlessly adjust the firmness while effectively solving the problem of soft layer displacement, making it more stable to use.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] An adjustable firmness and temperature mattress includes a support layer, a skin-friendly layer, and an intermediate layer disposed between the support layer and the skin-friendly layer. The support layer is located at the bottom of the mattress for support, and the skin-friendly layer is located at the top of the mattress for direct contact with the user. The intermediate layer is detachably disposed between the support layer and the skin-friendly layer. The intermediate layer includes an adjustable firmness layer, which includes a soft layer and a hard layer disposed opposite each other in the vertical direction. The hard layer is harder than the soft layer. The soft layer and the hard layer are an integral structure, so that the soft layer and the hard layer form an integral structural layer.

[0009] The beneficial effects of using this utility model are as follows:

[0010] Firstly, in this invention, since the middle layer is detachably located between the support layer and the skin-friendly layer, users do not need to flip the bottom support layer when adjusting the firmness. This is because the support layer generally includes metal springs and is the heaviest layer in the entire mattress. Therefore, it is not necessary to flip the support layer; only the middle layer needs to be flipped, which greatly increases the difficulty of adjustment and also saves more effort.

[0011] Secondly, in this invention, the hard layer and the soft layer are fixed to each other or form an integral structure, making them a single structural layer. Because the hard layer is relatively rigid and not easily bent or deformed, the possibility of overall displacement is low. Therefore, the hard layer effectively provides a fixed foundation for the soft layer. When the soft layer is subjected to force and tends to displace, it will be held back by the hard layer. Thus, the soft layer will always maintain overall consistency with the hard layer, significantly reducing the possibility of displacement.

[0012] Finally, other beneficial effects were discovered during actual use and testing. The integrated hard and soft layer structure of the intermediate layer makes it easier to remove or install from between the skin-friendly and support layers. For example, sometimes when users pull the intermediate layer out from between the skin-friendly and support layers, if the soft layer is separate, there will be significant resistance during the pulling process, and there is even concern that excessive force might damage the soft layer. However, with the soft and hard layers integrated into one structure, this is not a concern at all, as the hard layer is generally not easily damaged. Furthermore, during installation, traditional independent soft layers, due to their soft texture, have poor self-positioning, requiring users to carefully position them in all directions after flipping them. With this integrated soft and hard layer structure, the hard layer itself has excellent positioning, assisting in the positioning of the soft layer as the hard layer completes its positioning, eliminating the need for users to expend significant effort on positioning.

[0013] Preferably, the hard layer and the soft layer are made of 3D polymer material and are an integral structure.

[0014] Preferably, the adjustable layer includes a first planar layer, a second planar layer, and a connecting layer disposed between the first planar layer and the second planar layer. The first planar layer and the second planar layer are formed to have different hardnesses through different processes, thus forming the hard layer and the soft layer.

[0015] Preferably, the outer surface of the intermediate layer is covered with a covering layer, including a covering layer covering the surface of the hard layer and / or the soft layer.

[0016] Preferably, a reinforcing soft layer is provided between the soft layer and the covering layer, wherein the reinforcing soft layer is a bamboo charcoal cotton layer, gel memory foam, graphene sponge, or soybean fiber cotton.

[0017] Preferably, the coating layer is a 3D polymer network layer.

[0018] Preferably, the reinforcing soft layer is a 3D polymer layer and is embedded with cassia seeds.

[0019] Preferably, the support layer has an upwardly extending rim around its perimeter, which forms a receiving space, and the intermediate layer is at least partially contained within the receiving space.

[0020] Preferably, the edge of the covering layer is provided with edge support strips to prevent edge deformation.

[0021] Preferably, the intermediate layer comprises several intermediate layer units, and adjacent intermediate layer units are connected by detachable connectors. The detachable connectors are configured to allow connection when the soft layers of adjacent intermediate layer units face the same or opposite directions.

[0022] Preferably, the skin-friendly layer is provided with an upper connector, and the support layer is provided with a lower connector. The upper connector and the lower connector are detachably connected. After the skin-friendly layer is detached from the support layer through the upper connector, the middle layer is taken out and flipped for adjustment.

[0023] Preferably, the skin-friendly layer includes a warming layer and a cooling layer, wherein the cooling layer is made of a first material and the warming layer is made of a second material, and the thermal conductivity of the first material is greater than that of the second material.

[0024] Preferably, the upper connector includes a first upper connector and a second upper connector. The first upper connector is disposed near the warming layer, and the second upper connector is disposed near the cooling layer. Both the first upper connector and the second upper connector can be connected to the lower connector on the support layer.

[0025] Preferably, the first upper connector is an upper zipper, and the second upper connector is a lower zipper. The upper and lower zippers are spaced apart vertically, and when one of them is connected to the lower connector, the other is hidden in the space between the skin-friendly layer and the support layer.

[0026] Preferably, the skin-friendly layer further includes an interlayer disposed between the warming layer and the cooling layer, the interlayer being non-adhesive foam and / or elastic sponge and / or memory foam.

[0027] Preferably, the warming layer is made of pure cotton, linen, or velvet fabric; and / or, the cooling layer is made of ice silk fabric.

[0028] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0031] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are used only for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Example

[0034] like Figures 1 to 5 As shown in the illustration, this embodiment demonstrates a mattress, specifically an adjustable firmness and temperature control mattress. Its overall structure includes a support layer 1, a skin-friendly layer 3, and an intermediate layer 2 located between the support layer 1 and the skin-friendly layer 3. The support layer 1 is located at the bottom of the mattress for support and is typically made of a spring support layer 1 or a highly supportive material such as coconut fiber. The skin-friendly layer 3 is located at the top of the mattress for direct contact with the user, and the comfort of the fabric in the skin-friendly layer 3 is generally required.

[0035] like Figure 1 and Figure 3 As shown, in this embodiment, the intermediate layer 2 is detachably disposed between the support layer 1 and the skin-friendly layer 3. (Refer to...) Figure 3As shown, the intermediate layer 2 includes an adjustable-firm layer 20, which comprises a soft layer 201 and a hard layer 202 arranged opposite each other in the vertical direction. The hard layer 202 is harder than the soft layer 201. The soft layer 201 and the hard layer 202 are fixed to each other or are an integral structure, so that the adjustable-firm layer 20 forms a whole structural layer. Since the intermediate layer 2 is detachably located between the support layer 1 and the skin-friendly layer 3, when the user needs to adjust the firmness, there is no need to flip the bottom support layer 1. Because the support layer 1 generally includes metal springs, it is the heaviest layer in the entire mattress. Only the intermediate layer 2 needs to be flipped, which significantly increases the difficulty of adjustment but also saves more effort.

[0036] Secondly, since the rigid layer 202 and the soft layer 201 are fixed to each other or form an integral structure, they are a single structural layer. Because the rigid layer 202 has high hardness and is not easily bent or deformed, the possibility of overall displacement is low. Therefore, the rigid layer 202 effectively provides a fixed foundation for the soft layer 201. When the soft layer 201 is subjected to force and tends to displace, it will be held back by the rigid layer 202. Thus, the soft layer 201 will always maintain overall consistency with the rigid layer 202, significantly reducing the possibility of displacement.

[0037] Finally, other beneficial effects were discovered during actual use and testing: The intermediate layer 2, with its integrated structure of the rigid layer 202 and the soft layer 201, is more convenient to remove or install from between the skin-friendly layer 3 and the support layer 1. For example, sometimes when users pull the intermediate layer 2 out from between the skin-friendly layer 3 and the support layer 1, if the soft layer 201 were independent, there would be significant resistance during the pulling process. Users might even worry about damaging the soft layer 201 due to excessive force. However, by making the soft layer 201 and the rigid layer 202 an integrated structure… After installation, there is no need to worry about this situation at all, because the rigid layer 202 is generally not easily damaged. At the same time, during installation, the traditional independent soft layer 201, due to its soft texture, has poor self-positioning effect, and users need to carefully position it in all directions after flipping it over. However, with this integrated structure of the soft layer 201 and the rigid layer 202, the rigid layer 202 has excellent self-positioning effect due to its hard texture. When the rigid layer 202 completes its positioning, it also helps to position the soft layer 201, so users do not need to spend much effort on positioning it.

[0038] like Figure 3As shown, in this example, the hard layer 202 and the soft layer 201 are made of 3D polymer material and are an integral structure. 3D polymers are widely used in the mattress industry. Their main advantages are good breathability, light weight, and a certain degree of support. They can also effectively inhibit the growth of bacteria and mites, meaning they will not oxidize or mold, and have a good service life. In this embodiment, the hard layer 202 and the soft layer 201 are made of 3D polymer material as an integral structure. This structure and manufacturing process result in low production costs, and the hard layer 202 and the soft layer 201 can be very firmly bonded together.

[0039] To minimize interference between the soft layer 201 and the hard layer 202, the adjustable layer 20 in this embodiment includes a first planar layer, a second planar layer, and a connecting layer 203 between the first and second planar layers. This connecting layer 203 typically consists of several small support pillars; a mattress may have hundreds of thousands or even millions of these pillars to form support points, thus creating a buffer. When the soft layer 201 deforms under pressure, it will not directly press against the hard layer 202. In this embodiment, the first and second planar layers are processed to achieve different hardnesses. Such processes can be varied, for example, using different manufacturing temperatures to achieve different hardnesses in the first and second planar layers, thus forming the hard layer 202 and the soft layer 201.

[0040] To increase comfort, the intermediate layer 2 may also include a covering layer 22 that covers the surface of the rigid layer 202 and / or the soft layer 201. For example... Figure 3 As shown, in this embodiment, both the hard layer 202 and the soft layer 201 are covered with a covering layer 22. Of course, in other embodiments, the covering layer 22 may be provided only on the surface of the hard layer 202 or the soft layer 201. For the material of the covering layer 22, to maintain breathability, it is preferably a mesh layer made of 3D polymer, which allows for good air permeability among the soft layer 201, the hard layer 202, and the covering layer 22. Of course, in other embodiments, the covering layer 22 may also be made of other fabrics.

[0041] like Figure 5 As shown, the support layer 1 in this embodiment includes a plurality of independent pocket springs 11 arranged in a matrix, and also includes rectangular edge steel 12 disposed on the edges of all the independent pocket springs. The support layer 1 also includes a cover 13 that covers all the independent pocket springs and the edge steel, and the cover is made of large-mesh fabric and 4D fabric. The bottom of the independent pocket springs is also provided with a fiber cotton layer and a composite fabric layer.

[0042] To enhance the positioning effect of the intermediate layer 2 within the mattress, a perimeter 14 extends upwards from the perimeter of the support layer 1, forming a receiving space in which the intermediate layer 2 is at least partially accommodated. In this embodiment, a reinforcing rib is provided around the perimeter of the support layer 1 as the perimeter 14. This perimeter 14 serves two purposes: firstly, it provides a certain positioning effect for the intermediate layer 2; secondly, it acts as a base for sewing the lower connector, which is used to securely connect the support layer 1 to the skin-friendly layer 3. It should be noted that the height of the perimeter 14 can be selected according to actual needs and does not necessarily have to be the same as the height of the intermediate layer 2. For example, in this embodiment, the perimeter 14 is merely a reinforcing rib, and its height may be lower than that of the intermediate layer 2.

[0043] As shown above, in order to achieve a detachable connection between the skin-friendly layer 3 and the support layer 1, the skin-friendly layer 3 is provided with an upper connector 31 and the support layer 1 is provided with a lower connector. In this embodiment, the lower connector is located on the perimeter 14. The upper connector 31 and the lower connector are detachably connected. When the user needs to adjust the softness and hardness, the upper connector 31 and the lower connector can be disassembled to separate the skin-friendly layer 3 from the support layer 1. After disassembly, the middle layer 2 is taken out and then flipped for adjustment.

[0044] In addition, considering that the skin-friendly layer 3 of existing traditional bed sheets is only used on one side, users usually cannot make choices according to seasonal temperature changes. For example, in winter, users need to be able to touch the warmer skin-friendly layer 3, while in summer, users need to touch the cooler skin-friendly layer 3. However, existing bed sheets usually only have a single skin-friendly layer 3. Even if some mattresses can provide a double-sided sleeping experience, it still requires flipping the entire mattress, which is very laborious. Female users usually cannot flip and adjust it by themselves.

[0045] To address this issue, the skin-friendly layer 3 in this embodiment includes a warming layer 32 and a cooling layer 33. The cooling layer 33 is made of a first material, and the warming layer 32 is made of a second material. The thermal conductivity of the first material is greater than that of the second material. Because the thermal conductivity of the first material is greater than that of the second material, when a user comes into contact with the cooling layer 33 made of the first material, heat is quickly conducted, resulting in a cooling sensation on the skin surface. The first material can be a commonly available ice silk fabric, while the second material of the warming layer 32 can be a warmer material such as pure cotton, linen, or velvet.

[0046] In addition, since the skin-friendly layer 3 is detachably connected to the support layer 1 in this embodiment, when the user needs to flip the skin-friendly layer 3 for adjustment, there is no need to flip the support layer 1. Only the skin-friendly layer 3 needs to be flipped. Since the weight of the skin-friendly layer 3 is much less than the weight of the support layer 1, the user does not need to exert much effort to flip the skin-friendly layer 3. It is very easy to select the cooling layer 33 or the warming layer 32. Even female users can complete the flipping and adjustment by themselves.

[0047] Given that the skin-friendly layer 3 in this embodiment includes a cooling layer 33 and a warming layer 32, in order to ensure that the user can still connect to the support layer 1 after adjusting different surfaces, the upper connector 31 in this embodiment includes a first upper connector 311 and a second upper connector 312. The first upper connector 311 is located near the warming layer 32, and the second upper connector 312 is located near the cooling layer 33. When the user needs to adjust the warming layer 32 to face upwards, the first upper connector 311 is used to connect to the lower connector on the support layer 1. When the user needs to adjust the cooling layer 33 to face upwards, the second upper connector 312 is used to connect to the lower connector on the support layer 1.

[0048] In this embodiment, the first upper connector 311 is preferably an upper zipper, and the second upper connector 312 is preferably a lower zipper. The upper and lower zippers are arranged at intervals. When one of them is connected to the lower connector, the other is hidden in the space between the skin-friendly layer 3 and the support layer 1. This design allows the other upper connector 31 to be well hidden and not exposed when not connected, ensuring both aesthetic appearance and preventing the upper connector 31 from bumping or hitting the user.

[0049] To further enhance the comfort of the skin-friendly layer 3, in this embodiment, the skin-friendly layer 3 also includes an interlayer disposed between the warming layer 32 and the cooling layer 33. The material of the interlayer can be freely selected, preferably non-adhesive foam and / or elastic sponge and / or memory foam. Example

[0050] like Figure 6 As shown, the difference from Embodiment 1 is that, in this embodiment, to further enhance the comfort of the soft layer 201, a reinforcing soft layer 24 is also provided between the soft layer 201 and the covering layer 22. The reinforcing soft layer 24 is a bamboo charcoal cotton layer, gel memory foam, graphene sponge, or soybean fiber cotton. For customers who require a very soft sleeping feel, an additional layer can be added between the soft layer 201 and the covering layer 22, which can further reduce the firmness.

[0051] The reinforcing soft layer 24 can also be a 3D polymer layer. In this embodiment, the reinforcing soft layer can preferably be embedded with cassia seeds. The cassia seed particles are small and can be embedded in the mesh of the 3D polymer, which can still ensure the flatness of the mattress, fully exert the efficacy of cassia seeds, and not feel uncomfortable. Example

[0052] like Figure 7 As shown, in order to enable different areas of the same mattress to have different levels of firmness and comfort, the intermediate layer 2 is composed of several intermediate layer units 200. Adjacent intermediate layer units 200 are connected by detachable connectors. The detachable connectors are configured to be connected when the soft layers 201 of adjacent intermediate layer units 200 face the same direction or face opposite directions.

[0053] by Figure 7 For example, in this embodiment, the intermediate layer 2 includes two intermediate layer units 200, which are connected by a detachable connector 25. The detachable connector is preferably a two-way zipper. Figure 7 The image shows two intermediate layer units 200 with the soft layer 201 facing upwards. If the mattress is for two people, and one person wants to sleep on a firmer mattress while the other wants to sleep on a softer one, one of the intermediate layer units 200 can be flipped over so that the soft layer 201 faces down and the firm layer 202 faces up. Then, the mattress can be connected using the detachable connector 25. This way, the same mattress can be divided into two parts: one half is softer and the other half is firmer.

[0054] It should be noted that this embodiment only shows two intermediate layer units 200. In other embodiments, the number of intermediate layer units 200 is not limited to two, but can be five, six, seven, etc. The arrangement of the intermediate layer units 200 is not horizontal, but can also be vertical, to meet the softness and hardness requirements of different parts of the user's body.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
