Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the structure of a down quilt core, in particular to an overlapping and staggered warm-keeping down quilt. Background Art
[0002] Bedding refers to items placed on the bed for people to use when sleeping, including bedding, duvet covers, sheets, bedspreads, fitted sheets, pillowcases and pillow cores, etc. A quilt is a kind of bedding, generally used for keeping warm when sleeping, and is a rectangular cloth with an area large enough to cover the human body; down has a floret structure, and each down fiber has many diamond nodes, which are full of stagnant air, and a large amount of air is also fixed between the down fibers and the down clusters. This is the core principle of down's ability to keep warm. When the down is filled into the quilt shell, the space within the quilt shell's quilting lines determines whether the down can obtain the maximum fluffiness space. The fluffiness of the down also determines the thermal insulation performance of the down, thereby enhancing the thermal insulation effect of the down quilt, so it is necessary to develop a structure that has a larger space and can reduce the number of quilting lines running through the quilt shell.
[0003] Chinese Patent: A down quilt, Authorization Announcement Number: CN220631769U, Authorization Announcement Date: March 22, 2024. The down quilt can achieve compressed air on both longitudinal sides and the side close to the user's feet, but the cut-through or vertical lining compartment is relatively small, the down fluffy space is small, and it is difficult for the down to reach the optimal fluffy state. In addition, the down at the tangent line is less than that in the middle part. Due to the large area of the down quilt, the air is not circulated enough, which easily causes the user to feel hot and uncomfortable. It is necessary to propose a staggered overlapping down quilt to solve the above problems. Utility Model Content
[0004] The purpose of the present utility model is to provide a staggered overlapping duvet to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a staggered overlapping down quilt, comprising a quilt core body and a thermal insulation core group sewn above the quilt core body by quilting, the thermal insulation core group comprising a plurality of first thermal insulation core strips and a second thermal insulation core strips arranged in parallel, the first thermal insulation core strip and the second thermal insulation core strip both comprising a first fabric layer and a second fabric layer, the first fabric layer and the second fabric layer being connected by a quilting line, the transverse quilting lines of the plurality of first thermal insulation core strips and the transverse quilting lines of the plurality of second thermal insulation core strips being staggered, forming a plurality of staggered vertical lining structures visually on the whole, which can enhance the fluffy space of the fibers and obtain better thermal insulation performance, thereby solving the problem that the space of the existing quilt shell process is relatively small and there is less down at the through-type quilting lines, resulting in a decrease in the thermal insulation performance of the quilt core.
[0006] A further improvement of the present invention is that the two adjacent transverse quilting lines on the first thermal insulation core strip form a standing lining structure.
[0007] A further improvement of the present invention is that fillers are provided inside the vertical lining structure. Adding fillers inside the dislocation can make the whole body more fluffy and stretchable, lock more static air and make the quilt core warmer; it can better divide the compartments, and at the same time further ensure the compartment space, so that the quilt core can obtain better thermal insulation performance.
[0008] A further improvement of the present invention is that the width of the first thermal insulation core strip is greater than the width of the second thermal insulation core strip.
[0009] A further improvement of the present invention is that both ends of the first thermal insulation core strip and the second thermal insulation core strip are fixed on the quilt core body.
[0010] A further improvement of the present invention is that a hollow structure is formed between the lower portions of the first and second thermal insulation core strips and the quilt core body.
[0011] A further improvement of the present invention is that a first fold structure is provided between two adjacent quilting lines on the first thermal insulation core strip, and a second fold structure is provided between two adjacent quilting lines on the second thermal insulation core strip.
[0012] A further improvement of the present invention is that one side of the first crease structure corresponds to the quilting line on the second thermal insulation core strip, and one side of the second crease structure corresponds to the quilting line on the first thermal insulation core strip.
[0013] 1. Both ends of the first and second thermal insulation core strips are fixed to the quilt core body, which makes the down more fluffy and stretchy;
[0014] 2. The transverse quilting lines of several of the first thermal insulation core strips and the transverse quilting lines of several of the second thermal insulation core strips are staggered and sewn, forming several staggered vertical lining structures visually. This can prevent the transverse quilting lines from running through the entire quilt core, resulting in fewer cuts and, to a certain extent, increasing the cabin and making the down filling uniform, thereby achieving better warmth retention.
[0015] 3. A hollow structure is formed between the bottom of the first and second thermal insulation core strips and the quilt core body, so that the air channel is distributed throughout the quilt core, so that the air circulation inside the quilt core is smoother, thereby improving the heat problem of the down quilt core.
