Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile technology, specifically relating to an elastic down comforter. Background Technology
[0002] Down is an animal protein fiber, and its warmth retention is superior to plant-based cellulose fibers such as cotton. Furthermore, the down's spherical fibers are densely covered with millions of tiny triangular pores, which expand and contract with temperature changes, creating a temperature-regulating function. It absorbs heat dissipated by the body and insulates against the intrusion of cold air. Down comforters are comforters with down as the main filling. Down comforters have advantages such as high loft, rapid heating, lightness and softness, excellent warmth retention, breathability and dryness, close-fitting comfort, no pressure, automatic temperature regulation, moisture absorption and wicking, resistance to clumping, and long service life.
[0003] To improve the warmth of down comforters, a down comforter core has been disclosed in a related technology. The core consists of a face and an lining. The warp and weft yarns around the face and lining interweave to form a junction. The central warp and weft yarns interweave to form multiple grids, each with an opening. Down is filled into these grids, and the back is stitched with elastic bands. However, this down comforter core has seams in the head area, which can cause a foreign object sensation during use and friction against the neck, resulting in a poor user experience. Furthermore, the use of elastic bands throughout the entire comforter core increases the fabric area and manufacturing complexity, thus increasing production costs. Utility Model Content
[0004] In view of this, the present invention provides an elastic down comforter to solve the technical problem that the seams in the comforter head area cause a foreign body sensation during use, rub against the neck, and result in a poor user experience.
[0005] To achieve the above solution, the technical solution of this utility model is as follows:
[0006] This utility model provides an elastic down comforter, which is divided into a head section, a middle section and a tail section along its length. The head section is formed by folding a piece of fabric in half, with the folded part away from the middle section. The head section includes a number of elastic bands distributed along the length and width of the elastic down comforter, and all the elastic bands divide the head section into a number of first filling units.
[0007] The principle of this utility model of elastic down comforter is as follows: by setting the head of the comforter to be formed by folding a piece of fabric in half, and setting the folded part away from the middle part, the technical problem of foreign object feeling and friction on the neck caused by the seam in the head area can be avoided, thus improving the user experience; by using elastic band only in the head area and not the entire comforter area, the neck warmth and the three-dimensionality of the head area can be guaranteed while reducing production costs.
[0008] Optionally, the head and the middle part are connected by an elastic band.
[0009] Optionally, the width of the first filling unit is 16-20cm along the width direction of the elastic down comforter.
[0010] Specifically, this invention sets the width of the first filling unit to 16-20cm (usually 27.5cm in the prior art) along the width direction of the elastic down comforter. This allows the neck to be completely within the same filling unit during sleep, meaning that one filling unit can just completely cover the neck, improving the fit and warmth of the comforter and neck, and further enhancing the user experience.
[0011] Optionally, the middle portion includes a plurality of second filling units divided by quilting lines, wherein the area of the second filling unit is larger than the area of the first filling unit.
[0012] Specifically, this invention improves the warmth of the quilt head area by making the area of the second filling unit larger than that of the first filling unit, that is, the filling units of the quilt head are more dense than those of the middle part, thereby further enhancing the user's experience.
[0013] Optionally, the tail portion includes a plurality of third filling units divided by quilting, the area of the third filling units being smaller than the area of the second filling units.
[0014] Specifically, this invention improves the warmth retention of the tail area by setting the area of the third filling unit to be smaller than that of the second filling unit, that is, the filling units at the tail end are more dense than those in the middle part, thereby further enhancing the user experience.
[0015] Optionally, the area of the first filling unit located on the left and right sides of the elastic down comforter is smaller than the area of the first filling unit located in the middle of the elastic down comforter.
[0016] Optionally, the area of the second filling unit located on the left and right sides of the elastic down comforter is smaller than the area of the second filling unit located in the middle of the elastic down comforter.
[0017] Specifically, this invention improves the warmth of the left and right sides by making the area of the first filling unit located on the left and right sides of the elastic down comforter smaller than the area of the first filling unit located in the middle of the elastic down comforter, and / or making the area of the second filling unit located on the left and right sides of the elastic down comforter smaller than the area of the second filling unit located in the middle of the elastic down comforter. In other words, the filling units on the left and right sides are more densely packed than the middle, thereby improving the warmth of the left and right sides and further enhancing the user's experience.
[0018] Optionally, the edges of the first filling unit are provided with pleats.
[0019] Optionally, the edge of the third filling unit is provided with pleats.
[0020] Optionally, pleats are provided at the edges of the fourth filling unit and / or the substrate filling unit located around the perimeter of the elastic down comforter.
[0021] Specifically, this invention adds pleats to the edges of the first filling unit and / or the third filling unit and / or the edges of the second filling unit located around the perimeter of the elastic down comforter, thereby increasing the filling space of the filling unit in the corresponding area, improving the warmth retention effect of the corresponding area, and further enhancing the user's experience.
[0022] Optionally, the width of the pleats is 3-5 cm.
[0023] Optionally, the height of the pleats is 3-5 cm. Attached Figure Description

Along the length direction, the elastic down comforter is divided into a head section 11, a middle section 12 and a tail section 13. The head section 11 is formed by folding a piece of fabric in half, with the folded part away from the middle section 12. The head section 11 and the middle section 12 are connected by an elastic band.
[0036] The head of the comforter 11 includes several elastic bands 111 distributed along the length and width of the elastic down comforter. All elastic bands 111 divide the head of the comforter 111 into several first filling units 112. Along the width of the elastic down comforter, the width of the first filling unit 112 is 16-20cm.
[0037] The middle section 12 includes a plurality of second filling units 121 divided by quilting threads;
[0038] The tail portion 13 includes a plurality of third filling units 131 divided by quilting;
[0039] Pleats are provided at the edge of the first filling unit 112 and / or the edge of the third filling unit 131 and / or the edge of the second filling unit 121 located around the perimeter of the elastic down comforter. The width of the pleats is 3-5cm and the height of the pleats is 3-5cm.
[0040] In another embodiment, the area of the second filling unit 121 is greater than the area of the first filling unit 112 and / or the area of the third filling unit 131 is less than the area of the second filling unit 121.

[0042] The present invention will be described in detail below through specific examples and embodiments. It should also be understood that the following embodiments are only for specific illustration of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-essential improvements and adjustments made by those skilled in the art based on the above description of the present invention are within the scope of protection of the present invention. The specific process parameters, etc., in the following examples are merely examples within a suitable range; that is, those skilled in the art can make appropriate selections within the appropriate range based on the description herein, and are not intended to be limited to the specific values in the examples below.
[0043] Example 1
[0044] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the elastic down comforter in this embodiment. Along the length direction, the elastic down comforter is divided into the head part 11, the middle part 12 and the tail part 13.
[0045] Please continue reading. Figure 1The head section 11 refers to the part of the elastic down comforter closest to the head during sleep. The head section 11 is formed by folding a piece of fabric in half. The folded end, away from the middle section 12 (i.e., the end of the head section 11 closest to the head), has no seam. The cavity formed by the fold is filled with filling material. The head section 11 and the middle section 12 are connected by elastic bands. The filling material can be goose down, duck down, a mixture of goose down and duck down, or a mixture of at least one of goose down and duck down with synthetic fibers. The head section 11 includes several elastic bands 111 distributed along the length and width directions of the elastic down comforter. All elastic bands 111 divide the head section 111 into several first filling units 112. Along the width direction of the elastic down comforter, the width of the first filling unit 112 is 16-20cm. The edges of the first filling unit 112 have pleats, the width of which is 3-5cm and the height of which is 3-5cm.
[0046] Specifically, in this embodiment, by setting the width of the first filling unit 112 to 16-20cm (compared to 27.5cm in the prior art) along the width direction of the elastic down comforter, the neck can be completely contained within the same filling unit during sleep, meaning that one filling unit 16 can just completely cover the neck, improving the fit and warmth of the comforter and neck, thereby further enhancing the user experience. In this embodiment, by setting the first filling unit 111 to be divided by elastic bands 111 instead of quilted seams, the elastic bands 111 can increase the lateral and / or vertical tension in the head area when the user turns over while lying on their side, causing the head of the comforter to extend along the width and / or length direction. This avoids problems such as head displacement, poor warmth retention in the neck area, and a strong feeling of constriction from the comforter when the user turns over to tuck in the comforter during sleep, thus improving the warmth of the elastic down comforter and the user experience. This embodiment increases the filling space of the first filling unit 112 by adding pleats to the edge of the first filling unit 112, thereby improving the warmth retention effect of the quilt head area and further enhancing the user's experience.
[0047] Please continue reading. Figure 1The middle section 12 refers to the part located between the head section 11 and the tail section 13, and is connected to the head section 11 by an elastic band. The middle section 12 and the tail section 13 can be connected by quilting, and the quilting material can be natural fibers, synthetic fibers, or their blends, or the middle section 12 and the tail section 13 can be formed from the same piece of fabric. The tail section 13 refers to the part of the elastic down comforter near the feet during sleep, i.e., the head section 11 and the tail section 13 are distributed opposite each other. In other words, the middle section 12 and the tail section 13 can be made of two pieces of fabric, one as the outer fabric and the other as the lining fabric. The outer and lining fabrics are connected by quilting stitches to form areas corresponding to the head section 12 and the tail section 13, i.e., the head section 12 and the tail section 13 exist as a whole. Alternatively, the middle section 12 and the tail section 13 can be made of four pieces of fabric respectively: the outer fabric corresponding to the middle section 12, the outer fabric corresponding to the tail section 13, the lining fabric corresponding to the middle section 12, and the lining fabric corresponding to the tail section 13. The middle section 12 includes several second filling units 121 divided by quilting stitches, and the tail section 13 includes several third filling units 131 divided by quilting stitches. The second filling units 121 and the third filling units 131 are divided by quilting stitches, and the material of the quilting stitches can be natural fibers, synthetic fibers, or their blends. The edge of the third filling unit 131 is provided with pleats (not shown) and / or the edge of the second filling unit 121 located around the perimeter of the elastic down comforter is provided with pleats (not shown), the width of the pleats is 3-5cm and the height of the pleats is 3-5cm.
[0048] Specifically, this embodiment adds pleats at the edge of the third filling unit 131 and / or at the edge of the second filling unit 121 located around the perimeter of the elastic down comforter, which can increase the filling space of the comforter tail area and / or the surrounding filling units, improve the warmth of the corresponding areas, and further enhance the user's experience.
[0049] The principle of the elastic down comforter in this embodiment is as follows: by setting the head of the comforter 11 to be formed by folding a piece of fabric in half, and setting the folded part away from the middle part 12, the technical problem of foreign object feeling and friction on the neck caused by the seam in the head area can be avoided, thereby improving the user experience; by using elastic band only in the head of the comforter 11 and not the entire area of the comforter, the production cost can be reduced while ensuring the warmth of the neck and the three-dimensionality of the head area.
[0050] Example 2
[0051] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of the elastic down comforter in this embodiment.
