Patent Application
20210274944
Common mattresses include integrated spring mattresses, such as those with chain spring nets and independent pocket springs. Such conventional mattresses have an integrally sutured internal arrangement and can be divided into pure innerspring mattresses, brown spring mattresses, foam and innerspring mattresses, and spring and latex mattresses.
Conventional mattresses are non-replaceable, non-removable and washable, and cannot be cleaned easily. During long-term use, dust and human dander will continue to be deposited on the mattress fabric and inner cushion materials, which may breed bacteria and mites that can endanger the health of users. According to manufacturer specifications, mattress should be considered for replacement after about five years of use, though the lifespan of a mattress is generally more than ten years. Replacing a mattress this frequently results in a high cost to the user.
In addition, mattresses with a fixed internal configuration and structure cannot meet the needs of users who may simultaneously need mattresses having a different firmness. Such mattresses therefore lack the flexibility for users to choose a mattress suitable for their own comfort when used by two people.
There remains a need for a mattress that can be replaced, washed, detached, and easily adjusted and replaced. The present mattress design fulfills this need by providing modular and standardized mattress components, which can be separated and replaced to reduce the user's cost. The use of modular components also makes it more convenient for the user to clean, dry, and replace a mattress and to provide different comfort levels.
The present dual core mattress includes a removable upper cover, an upper mattress layer below the upper cove, and a bottom mattress layer below the upper mattress layer. The upper cover has an upper cover zipper portion which extends around the lower periphery of the upper cover on a lower peripheral edge and includes downwardly extending zipper teeth. The upper mattress layer is positioned below the upper cover and lies on the upper surface of the bottom mattress layer. The bottom mattress layer further includes a waterproof material on the upper surface, an upper strip tape with an upper positioning zipper portion, and a lower strip tape with a lower positioning zipper portion. The upper positioning zipper portion and upper strip tape extend around the periphery of the bottom mattress layer at an upper end, and the lower positioning zipper portion and lower strip tape likewise extend around the periphery of the bottom mattress layer but vertically below the upper strip tape. In this way, the upper cover zipper portion can be removably secured to the upper positioning zipper portion when the upper mattress layer is positioned on the upper surface of the bottom mattress layer, and can be removably secured to the lower positioning zipper portion when the upper mattress layer is positioned on the upper surface of the bottom mattress layer, thereby allowing the dual core mattress to be have two different vertical heights.
The upper and lower mattress layers can be made from different materials and have a different firmness. In one embodiment, the upper mattress layer comprises two separate pieces, so that each piece can be formed from different materials and have a different firmness. For example, the upper mattress layer pieces can each be made from a material selected from the group consisting of gel memory foam, high-resilience foam, and natural latex cotton. The bottom mattress layer on the other hand can comprise high-resilience foam, chain net springs, or pocketed coils.
The reference numbers in the drawings designate the following components of the present appliance:
The present invention provides a modular mattress having components which are standardized, detachable and replaceable in order to reduce the long term cost of the mattress. The present mattress is also convenient for the user to maintain, including easier drying and replacement. In addition, a user of the present mattress can experience different a firmness and/or mattress height with the present mattress assembly in order adjust the mattress for the user's comfort, which can be accomplished by changing or removing one or more mattress components. Firmness can be measured according to measures used in the industry, for example according to ASTM standard F1566 or by Indentation Force Deflection (IFD) Testing according ASTM standard D3574 (promulgated by ASTM International), and mattresses with different firmnesses preferably differ in firmness by at least 5-10% or more.
One embodiment of the present dual core mattress is shown in
The upper mattress layer 03 is paced on a bottom mattress layer 09, as shown for example in
The upper replaceable mattress 03 (
The bottom mattress layer 09 (
As shown in
The bottom mattress layer 09 can be a different type of mattress, or can be formed from a different material, than the upper mattress layer (03, 10, and 11). For example, the bottom mattress layer 09 can be a high-resilience foam, chain net spring, or pocketed coil mattress. The complete mattress assembly (
Compared with a traditional integrated mattress, the present mattress has the following beneficial effect of reducing the cost and expenses to a user because the mattress components can be standardized while still allowing customization of the mattress. The mattress components can also be detached and replaced, so that it is convenient for the user to clean, air-dry, and replace the mattress. Mattress components can also be replaced with components made from different materials or constructions, so that the user can experience different comfort levels. The mattress thus has a flexible design and is convenient for hygienic care and replaceability.
The examples set forth herein are provided to illustrate certain concepts of the disclosure. The apparatus, devices, or components illustrated above may be configured to perform one or more of the methods, features, or steps described herein. Those of ordinary skill in the art will comprehend that these are merely illustrative in nature, and other examples may fall within the scope of the disclosure and the appended claims. While the above descriptions contain many specific embodiments of the invention, these should not be construed as limitations on the scope of the invention, but rather as examples of specific embodiments thereof.
The terms “above,” “below,” “higher, “lower,” “between,” and other terms of relative position or orientation as used herein refer to a relative position of one layer with respect to other layers, generally with reference to a support surface on which the present mattress is supported, such as a floor. “Vertical” and “horizontal” are likewise used in relation to such a support surface.
The term “comprise” and variations of the term, such as “comprising” and “comprises,” are not intended to exclude other additives, components, integers or steps. The terms “a,” “an,” and “the” and similar referents used herein are to be construed to cover both the singular and the plural unless their usage in context indicates otherwise. Ranges which are described as being “between” two values include the indicated values.
