[0031] Quilts are common bedding items in everyday life, primarily used for warmth. During cold weather, people often cover themselves with quilts to maintain warmth and improve sleep quality. Quilts come in a variety of materials and types, including down, cotton, and wool. Different materials offer different characteristics. For example, down quilts are lightweight and offer excellent warmth, while cotton quilts are more breathable and comfortable.

[0032] A quilt is generally composed of a quilt cover and a quilt core. The existing quilt has an opening on one side of the quilt cover, and a zipper is installed at the opening. The quilt core is inserted into the inner side of the quilt cover through the opening. When installing or removing the quilt core of such a quilt, the quilt core can only be inserted or removed from the opening on one side of the quilt cover. The operating space is too small, and it is inconvenient to replace the quilt core.

[0033] See also Figure 1 and Figure 4The present invention proposes a quilt cover 100 that is easy to disassemble and install a quilt core, comprising a main body 11 and a zipper 12. The main body 11 comprises a first sheet 111 and a second sheet 112 that are connected to each other. The first sheet 111 is formed with an inner cavity 111a and a U-shaped opening that are interconnected. The second sheet 112 is used to cover the U-shaped opening. One sprocket 123 of the zipper 12 is distributed on the outer periphery of the second sheet 112, and another sprocket 123 of the zipper 12 is distributed on the inner periphery of the U-shaped opening. The distance between the top of the zipper 12 and the upper edge of the first sheet 111 is greater than or equal to 60 cm, and the distance between the two sides of the zipper 12 and the two side edges of the first sheet 111 is greater than or equal to 30 cm. Specifically, a U-shaped opening is designed on the main body of the quilt cover 1, and two U-shaped sprockets 123 are used to expand the operating range of removing and installing the quilt core 2, and the installation position of the quilt core 2 can be positioned to ensure the installation accuracy. When installing the quilt core 2, the two U-shaped sprockets 123 are separated from each other until the complete U-shaped opening is exposed, the first quilt sheet 111 fabric inside the U-shaped opening is turned forward to expose a larger operating area, and the quilt core 2 is smoothly inserted into the inner cavity 111a, and then the two U-shaped sprockets 123 are closed to each other, and the two U-shaped sprockets 123 are sealed, thus completing the installation of the quilt core 2. When the quilt core 2 needs to be disassembled, the two U-shaped sprockets 123 are separated from each other again until the complete U-shaped opening is exposed, and then the quilt core 2 in the inner cavity 111a can be taken out; the single chamfer 3 is always facing one side In this embodiment, the single inverted edge 3 is tilted toward the first sheet 111, so that the zipper 12 can be blocked by the single inverted edges 3 on both sides of the second sheet 112, which can further increase the invisibility of the two sprockets 123, further making the quilt cover 1 beautiful. Even after the quilt cover is washed, the single inverted edge will tilt toward the first sheet 111 to block the zipper. Compared with the conventional quilt cover 1 with a zipper 12 on one side, the quilt cover 1 of the quilt in this embodiment has a U-shaped opening, which greatly increases the area of ​​the operating space, thereby increasing the user's operating area and facilitating the user's installation and disassembly of the quilt core 2.

[0034] Furthermore, the quilt cover 1 is pre-shrunk and then sewn to avoid bulging caused by the different shrinkage rates of the zipper 12 and the quilt cover 1.

[0035] See also Figure 1 and Figure 4 In one embodiment, the bottom of the U-shaped opening is located at the lower edge of the first sheet 111. Since textile fabrics are stretched during production, the finished fabric will experience significant shrinkage in the weft direction. In this embodiment, the U-shaped opening is located at the lower edge of the first sheet 111. When the zipper 12 is installed on the U-shaped opening, even if the duvet cover 1 shrinks, the zipper 12 will not be affected by the shrinkage, ensuring normal operation of the zipper 12.

[0036] Furthermore, the zipper 12 is configured as a soft zipper 12, which is comfortable and soft. Thus, even if a user touches the zipper 12 during use, the user will not be affected by the zipper 12, and the soft zipper 12 can bend as the quilt bends.

[0037] In one embodiment, two sprockets 123 are respectively installed on the inner sides of the first sheet 111 and the second sheet 112. The two sprockets 123 are respectively installed on the inner sides of the first sheet 111 and the second sheet 112. In this way, the two sprockets 123 are installed in reverse, and the two sprockets 123 are invisible in the quilt cover 1, which increases the invisibility of the two sprockets 123. Even if the zipper 12 is washed and reused many times, the zipper 12 cannot be seen, making the quilt cover 1 beautiful.

[0038] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In one embodiment, the distance between the top of the zipper 12 and the upper edge of the first sheet 111 is greater than or equal to 60 cm, and the distances between the two sides of the zipper 12 and the two side edges of the first sheet 111 are greater than or equal to 30 cm. A certain distance is set between the top of the U-shaped sprocket 123 and the upper edge of the first sheet 111, and a certain distance is set between the two sides of the U-shaped sprocket 123 and the two side edges of the first sheet 111. For example, when the length of the first sheet 111 is 2300 mm and the width is 2000 mm, the overall width of the U-shaped opening can be 1200 mm, the distance between the top of the U-shaped sprocket 123 and the upper edge of the first sheet 111 can be 600 mm, and the distance between the two sides of the U-shaped sprocket 123 and the two side edges of the first sheet 111 is 300 mm. For these 6 00mm and 300mm, which is enough for the user's head, arms and hands to move, and the user can roll over in sleep and hug the quilt without touching the zipper 12, which is comfortable and has no foreign body sensation. In addition, the 30cm distance can collect the quilt corners of the quilt core 2, which has the effect of putting it into a pocket, and can better fix the position of the quilt, greatly improving the user's comfort. In fact, the distance between the top of the zipper 12 and the upper edge of the first quilt sheet 111 can also be greater than or equal to 0, and the distance between the two sides of the zipper 12 and the two side edges of the first quilt sheet 111 can also be greater than or equal to 0, so that the user will not feel the existence of the zipper when using it.

[0039] Furthermore, the single-side pressing technology is used to sew the single inverted edge 3 so that the zipper 12 will not bulge out of the quilt cover 1.

[0040] See also Figure 6In one embodiment, the quilt cover further includes two connecting edges 6, with two sprockets mounted on the two connecting edges 6, respectively, connecting the two connecting edges 6 to the first sheet 111 and the second sheet 112, respectively. The width of the connecting edges 6 at the rounded transition is greater than the width of the rest of the connecting edges 6. The bottom corners of the two U-shaped sprockets 123 are designed with widened connecting edges 6, so that the zipper can smoothly pass through right-angle bends, solving the problem of ordinary zippers 12 being unable to make right-angle bends and achieving smooth turning of the zipper 12.

[0041] See also Figure 3 In one embodiment, the zipper 12 further includes two sliders 121 and two operating rods 122 provided on the sprocket bar 123, and the operating rods 122 are rotatably mounted on the sliders 121. By providing the operating rods 122 rotatably mounted on the sliders 121, the user operation is smoother.

[0042] According to another aspect of the present invention, please refer to Figure 1 、 Figure 4 and Figure 7 The utility model also discloses a quilt comprising a quilt core and the quilt cover 100 that is easy to disassemble and install the quilt core. The quilt cover 100 that is easy to disassemble and install the quilt core also comprises a connecting component 4 and a quilt corner sticker 5. One of the connecting component 4 or the quilt corner sticker 5 is arranged on the quilt core 2; the other of the connecting component 4 or the quilt corner sticker 5 is arranged in the inner cavity 111a and is connected to the quilt cover 1. The connecting component 4 and the quilt corner sticker 5 can be connected to each other. Specifically, when installing the quilt core 2, the two U-shaped sprockets 123 are separated from each other until the complete U-shaped opening is exposed, the first quilt sheet 111 fabric inside the U-shaped opening is turned forward to expose a larger operating area, and the quilt core 2 is smoothly inserted into the inner cavity 111a, and then the connecting component 4 and the quilt corner sticker 5 are connected, and then the two U-shaped sprockets 123 are closed to each other, and the two U-shaped sprockets 123 are sealed, so that the installation of the quilt core 2 is completed. When the quilt core 2 needs to be disassembled, the two U-shaped sprockets 123 are separated from each other again until the complete U-shaped opening is exposed, and then the connecting component 4 and the quilt corner sticker 5 are disassembled, and then the quilt core 2 in the inner cavity 111a is taken out. By setting the connecting component 4 and the quilt corner sticker 5, the quilt core 2 can be prevented from moving in the quilt cover 1; the glue of the quilt corner sticker 5 is washable and will not fall off even after washing.

[0043] See also Figure 1 、 Figure 4 and Figure 7In one embodiment, the number of connecting components 4 and quilt corner stickers 5 are both four. The four quilt corner stickers 5 are detachably mounted on the four corners of the quilt core 2, and the four connecting components 4 are respectively arranged at the four corners of the quilt cover 1, and the four connecting components 4 are all arranged in the inner cavity 111a. The colors of the four connecting components 4 are different, and the colors of the four quilt corner stickers 5 are arranged in a one-to-one correspondence with the colors of the four connecting components 4. A double quilt is nearly square, and it is difficult to find the direction when changing the quilt cover 1 or the quilt core 2, and the quilt corner stickers 5 of the corresponding colors are often changed in the wrong direction. By setting four connecting components 4 of different colors on the four corners of the quilt cover 1, and then sticking the quilt corner stickers 5 of the corresponding colors on the four corners of the quilt core 2, the connecting components 4 of the corresponding colors are connected to the quilt corner stickers 5, so that the problem of losing the direction will not occur.

[0044] See also Figure 1 、 Figure 4 and Figure 7 In one embodiment, the connection component 4 includes two connection belts 41. The connection belts 41 are elastic belts. One end of the connection belts 41 is provided with a limiter. The quilt cover 1 is formed with a telescopic hole. The connection belts 41 are telescopically installed in the telescopic hole. The limiter is used to abut against the outer surface of the quilt core 2. The connection belts 41 are set as elastic belts. In this way, when the connection component 4 is not connected to the quilt, the connection belts 41 will retract into the telescopic hole. The limiter abuts against the outer surface of the quilt core 2, preventing the connection belts 41 from fully extending into the telescopic hole, resulting in the connection belts 41 being unable to be pulled out. Then, when the quilt core 2 is installed, the elastic belts are pulled out and connected to the quilt corner stickers 5. After the connection is completed, the elastic belts will retract, and the quilt core 2 and the quilt cover 1 will fit tightly together, ensuring that the quilt core 2 and the quilt cover 1 are completely fitted together.

[0045] In one embodiment, the two connecting straps 41 are respectively provided with a female buckle and a male buckle, and the female buckle and the male buckle can be connected to each other. By providing the female buckle and the male buckle respectively on the two connecting straps 41, when connecting with the quilt corner sticker 5, one connecting strap 41 is passed through the quilt corner sticker 5, and then the female buckle and the male buckle on the two connecting straps 41 are connected to each other, thus completing the installation. Compared with passing the two connecting straps 41 through the quilt corner sticker 5 and then tying the two connecting straps 41 together to connect the connecting assembly 4 to the quilt corner sticker 5, the present embodiment connects the connecting assembly 4 to the quilt corner sticker 5 by connecting the female buckle and the male buckle, which greatly improves the connection efficiency, reduces the difficulty of operation, and prevents the quilt from separating from each other, thereby improving the connection strength between the connecting assembly 4 and the quilt corner sticker 5.

[0046] The above are merely exemplary embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
