Technical Field

[0001] This utility model belongs to the field of textile technology, specifically relating to a down comforter that can be adjusted to function as a sleeping bag. Background Technology

[0002] Traditional home bedding and outdoor gear exhibit clear distinctions in appearance and function, reflecting different application scenarios and product categories. Take down comforters as an example: traditional down comforters utilize a high-loft filling structure, providing excellent warmth and comfort in a static sleeping environment, but they struggle to meet the demands of dynamic outdoor use. Outdoor sleeping bags, with their enveloping structure, effectively insulate users in low temperatures or strong winds; however, the limited internal space of the cylindrical shape makes them unsuitable for comfortable home use. Existing products are mostly designed for single environmental conditions, lacking flexibility and adaptability. Utility Model Content

[0003] This utility model aims to provide an adjustable down comforter that can be converted into a sleeping bag. Through modular design, it integrates the functions of a comforter and a sleeping bag, solving the technical problems of existing technologies where the functions of sleeping bags and comforters are separated, usage scenarios are limited, and a dynamic balance cannot be achieved between the flexibility of the comforter and the warmth of the sleeping bag, resulting in single functions and redundant storage.

[0004] This utility model is achieved through the following technical solution: an adjustable down comforter that can be converted into a sleeping bag, the down comforter including a comforter body, an opening and closing component, and an adjusting component, the opening and closing component including a two-way zipper system, the two zipper straps of the two-way zipper system being respectively located on the two long sides of the comforter body, the two-way zipper system also including two oppositely arranged zipper heads for controlling the opening and closing of the two zipper straps; the adjusting component including a drawstring groove and a drawstring strap, the two drawstring grooves being respectively encircled on the two short sides of the comforter body, each of the two drawstring grooves having a drawstring strap, the two ends of each drawstring strap extending out of the drawstring groove and connected to a zipper head on the same side.

[0005] Furthermore, the quilt body includes an outer windproof and waterproof coated fabric, an inner moisture-wicking and breathable fabric, and a sandwich layer. The sandwich layer is formed by dividing the outer windproof and waterproof coated fabric and the inner moisture-wicking and breathable fabric into multiple sections filled with down through quilted partition lines.

[0006] Furthermore, fasteners for securing the pull cord are provided at both ends of the pull cord extending from the pull cord groove.

[0007] Furthermore, the adjusting component also includes a hook and loop fastener assembly, which includes multiple hook and loop fasteners distributed along the quilting section lines. Each hook and loop fastener includes a hook-and-loop fastener on one of the long sides and a loop fastener on the other long side. The spacing between two adjacent hook and loop fasteners is 20-30 cm.

[0008] Furthermore, the down comforter also includes decorative components disposed on the four sides of the comforter body, the decorative components being three-dimensional edge reflective strips.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] (1) The form of the down comforter and sleeping bag can be transformed by the linkage of the two-way zipper system and the pull-out rope, taking into account the flexibility of the bedding and the wrapping of the sleeping bag, meeting the needs of use in all scenarios such as home, outdoors and emergency, and effectively reducing the storage volume.

[0011] (2) When transformed into a sleeping bag, a cocoon-shaped bionic system is realized to achieve 360° bionic wrapping and form a double-sided breathable chamber in space to absorb moisture and breathe, avoiding stuffiness.

[0012] (3) Three-dimensional quilting and partitioned filling ensures uniform distribution of down under different usage conditions, prevents down displacement, and uniformly locks in temperature. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the structure of the quilt when it is converted into a sleeping bag according to this utility model;

[0015] The features include: 1. drawstring; 2. Velcro closure; 3. two-way zipper system; 4. down filling; 5. quilted seam dividers; and 6. three-dimensional reflective edge strips. Detailed Implementation

[0016] The present invention will now be described in conjunction with the accompanying drawings and specific embodiments.

[0017] This invention allows a down comforter to be converted into a cocoon-shaped sleeping bag by closing the two-way zipper system and tightening the drawstring. By unfolding the two-way zipper system and separating the Velcro closure, it can be restored to a regular comforter shape. During use, the cocoon-shaped sleeping bag forms breathable compartments on both sides inside, which absorb moisture and prevent stuffiness.

[0018] This invention utilizes a two-way zipper system and adjustable components to achieve rapid transformation between a comforter and a sleeping bag. The three-dimensional quilting maintains even distribution of down, while the drawstring and Velcro closures work together to create a three-dimensional enclosed space, suitable for use in various scenarios such as home, camping, in the car, and in emergencies. It boasts advantages such as high functional integration, convenient transformation, and reduced storage volume.
