Description

Technical Field

[0001] This invention belongs to the field of home furnishing technology, specifically relating to a mattress, and more particularly to a detachable mattress with a double-layer zipper structure that can be used in both winter and summer. Background Technology

[0002] As people's living standards improve, their demands for the functionality and comfort of mattresses in different seasons are increasing. In winter, when temperatures are low, people tend to use mattresses that are soft and warm to achieve a more comfortable sleep experience; while in summer, when temperatures rise, mattresses need to be breathable to avoid feeling stuffy.

[0003] Currently, most mattresses on the market are designed for a single season. To meet the needs of both winter and summer use, it is often necessary to purchase different types of mattresses or frequently change bedding, which not only increases economic costs but also brings the hassle of storage and replacement. Although some removable mattresses attempt to adapt to the seasons by changing the padding layers, they have obvious shortcomings: First, the functions of the padding layers are not clearly differentiated, failing to accurately meet the needs of increased softness and comfort in winter and the requirements of breathability and coolness in summer; second, the connection structure design is unreasonable, often using single-layer zippers or Velcro, resulting in poor stability of the connection between the padding layers and the mattress body, making them prone to shifting during use; third, zipper heads and other connecting parts are exposed, which can cause discomfort when in contact with the body, affecting sleep comfort, and the gaps are prone to dust accumulation, making cleaning inconvenient.

[0004] Especially in winter use scenarios, there is a lack of structural design specifically for enhancing softness and comfort; while in summer, the extra padding layers can cause stuffiness and discomfort, and are difficult to remove easily. Therefore, there is an urgent need for a mattress structure that can clearly distinguish between winter and summer functions—in winter, adding a top pad to increase softness and comfort, and in summer, removing the top pad to keep it cool and breathable, while also being securely connected, comfortable to use, and easy to clean—to solve the problems existing in current technology. Summary of the Invention

[0005] To solve the above problems, this utility model provides a double-layer zippered, detachable mattress suitable for both winter and summer, the specific technical solution of which is as follows:

[0006] The double-layer zippered removable mattress is suitable for both winter and summer use. It includes the mattress body, a mattress cover that is put on the outside of the mattress body, a top layer and a top layer.

[0007] The mattress cover has parallel inner and outer zippers sewn along the top edge, and a first fastening piece is provided in the middle of the foot of the mattress cover.

[0008] The surface pad has a first connecting part at its edge that is adapted to the inner ring zipper, and the surface pad is detachably connected to the inner ring zipper through the first connecting part; the surface pad includes an edge part made of woven fabric along its four sides, and a contact part made of knitted fabric on the inner side of the edge part;

[0009] A flared opening is sewn around the bottom edge of the top pad at a predetermined inward distance. The free end of the flared opening has a second connecting part that matches the outer zipper. The top pad is detachably connected to the outer zipper through the second connecting part. A double-layered structure is formed between the flared opening and the bottom of the top pad. Ear protectors are sewn near the foot of the bed and at the end of the second connecting part. The ear protectors have a second fastening component that matches the first fastening component. The first fastening component and the second fastening component constitute a fastening assembly.

[0010] When the ear flaps are secured to the mattress cover via the fastening assembly, they cover and wrap around the zipper heads of the inner and outer zippers.

[0011] Preferably, the first fastening element is a button with a protrusion, and the second fastening element is a buttonhole adapted to the protrusion.

[0012] Preferably, the first fastening element is a snap-fit ​​protrusion, and the second fastening element is a snap-fit ​​groove that engages with the snap-fit ​​protrusion.

[0013] Furthermore, the edges of the ear protectors are arc-shaped, matching the contours of the zipper head distribution areas of the inner and outer zippers, and the length of the ear protectors is 8-15cm and the width is 5-10cm.

[0014] Preferably, the ends of the inner and outer zippers are parallel to each other and spaced 1-3cm apart, and the inner edge of the ear flap is aligned with the outer edge of the two zipper ends; the length of both the inner and outer zippers is not less than 3 / 4 of the circumference of the top surface of the mattress cover.

[0015] Preferably, the preset distance is 3-8cm, so that the width of the double-layered structure is 3-8cm.

[0016] Preferably, the width of the edge portion is 10-20cm, and the area of ​​the contact portion accounts for more than 60% of the total area of ​​the surface pad.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The top pad is removable via a double-layer zipper. In winter, adding the top pad enhances softness, comfort, and support; in summer, removing it allows the knitted contact area of ​​the top pad to maintain high breathability and a cooling sensation. This eliminates the need for additional bedding, reducing costs and simplifying the process. The inner and outer zippers connect the top and bottom pads respectively, forming a double-fixed structure. This significantly reduces pad displacement compared to traditional connection methods, ensuring structural integrity during use. The double-layer zipper structure allows for separate removal of both winter and summer pads, ensuring a secure connection, comfortable use, and easier cleaning and replacement. The double-layered flared structure of the top pad enhances cushioning. Ear protectors cover the zipper heads to prevent discomfort, and their edges conform to the zipper head distribution contours, improving fit and comfort. The removable design of the top and bottom pads facilitates individual washing and replacement. The ear protectors reduce dust accumulation in zipper gaps, simplifying cleaning. The woven edge of the top pad enhances wear resistance, while the knitted contact area ensures skin-friendliness. Detailed design elements such as zipper spacing and flared size ensure tight connections and reasonable stress distribution, extending the lifespan of the components. Attached Figure Description
