Abstract
Description
Technical Field
[0001] This utility model relates to a quilt structure, particularly a quilt with a double-layered headboard, suitable for use in patient care and also for improving sleep quality for ordinary people. This utility model also relates to a special quilt cover for this quilt. Background Technology
[0002] Sleep is an eternal topic in human life, and improving sleep quality is an ongoing process. It has been noted that many people have the habit of keeping their hands outside the covers while sleeping. To accommodate this habit, and also to meet the warmth needs of ordinary people, a quilt called "Partially Layered Quilt" has been designed (see Chinese Patent 2023221550754). Its structure features a double-layered headboard, with a vertical layer at one end of the headboard, building upon the traditional quilt design. The front of this vertical layer is open, while the left, right, and bottom are closed, creating a pocket-like space within. While sleeping, in addition to being fully covered by the quilt, the hands and arms can be placed within this pocket-like space. This not only effectively maintains close contact between the chest and abdomen and the quilt, providing warmth, but also keeps the outstretched hands warm while allowing for relative freedom of movement.
[0003] The aforementioned structure addresses the issue of hands getting cold when left outside the blanket, but it doesn't fully achieve the goal of freeing up the hands. It only allows for separate sleeping of the hands and torso. When the hands and arms are placed inside the interlayer pocket, the closed sides of the interlayer restrict the range of hand movement, resulting in a certain sense of constraint and limited hand space.
[0004] Furthermore, current patient care blankets are all traditional single-piece structures. However, patients differ from healthy individuals; they require rest and should not engage in excessive activity. Maintaining adequate warmth, especially to the torso, is crucial, requiring coverage of the chest, abdomen, and lower body, while keeping arms exposed as much as possible, such as during intravenous infusions, blood pressure measurements, heart rate checks, or monitoring. Because traditional nursing blankets are structurally similar to ordinary thermal blankets, during prolonged infusions, hands, arms, and even shoulders must be exposed outside the blanket. While the main body of the blanket can still cover the body, gaps and air leaks at the contact points between the arms and the blanket, potentially leading to inadequate coverage of the chest and abdomen. Measuring blood pressure requires extending the arm out of the blanket and then retracting it afterward, causing considerable inconvenience. Therefore, it is necessary to improve nursing blankets to better suit patient care.
[0005] Furthermore, many young people have the habit of playing games or using their phones in bed. In cold environments, their arms not only have to stick out of the blanket, but they also have to place the game console in front of their chest, exposing their chest and abdomen, making them more susceptible to catching a cold.
[0006] In view of the shortcomings of ordinary quilts, the problem that the partial interlayer is closed on both sides, which restricts hand movement, and the problem that it is not well suited for patient care, the designer has made further improvements to the above-mentioned quilt structure. Utility Model Content
[0007] The purpose of this utility model is to provide a double-layered quilt head blanket that allows for greater hand movement while sleeping, prevents the hands from getting cold, and does not affect the coverage of the chest and abdomen, making it more suitable for patient care.
[0008] Another objective of this invention is to provide a duvet cover specifically designed for double-layer duvet covers, which helps keep the double-layer duvet covers clean and is easy to disassemble and wash.
[0009] This utility model also provides a double-layer quilt cover combination structure, which is a double-layer quilt cover composed of a finished quilt core and a special quilt cover using the above-mentioned double-layer quilt cover structure.
[0010] The double-layered quilt head of this utility model includes a double-layered quilt head and a normal main body. The double-layered quilt head includes an outer quilt body and an inner quilt body that are overlapped and independently arranged. The normal main body is a quilt body with a normal structure. The quilt body of the normal main body and the inner and outer quilt bodies of the double-layered quilt head are quilted and edge-sealed respectively. The rear ends of the outer and inner quilt bodies of the double-layered quilt head are integrally quilted or sewn together with the front end of the quilt body of the normal main body in the length direction, forming an open space with openings at the front end and on the left and right sides of the double-layered quilt head.
[0011] In the aforementioned double-layered quilt head, the length of the double-layered quilt head roughly corresponds to the sum of the arm and hand lengths of the corresponding user group; the total thickness of the double-layered quilt head is roughly the same as the thickness of the typical main body.
[0012] In the aforementioned double-layered quilt cover, the double-layered quilt cover is integrally and continuously formed with the main body; it includes an outer fabric, inner and outer quilt cores, an inner fabric, an outer lining, and an inner lining; wherein the outer fabric, inner and outer quilt cores, and inner fabric are all integrally continuous in the length direction; the inner and outer quilt cores are double or multiple layers stacked and wrapped inside the outer and inner fabrics; the outer lining is located inside the outer quilt core of the quilt cover, and the inner lining is located outside the inner quilt core, with the lengths of the outer and inner linings corresponding to the length of the double-layered quilt cover; the inner and outer quilt bodies of the normally structured quilt and the double-layered quilt cover are respectively quilted and edge-sealed.
[0013] In the aforementioned double-layered quilt head, the outer layer of the double-layered quilt head is provided with an extension portion extending towards the quilt head end. The extension portion is integrally formed with the outer layer and the length of the extension portion is between 15 and 30 centimeters.
[0014] In the aforementioned double-layered quilt head, the edges of the inner and outer quilt bodies are provided with corresponding movable connecting devices.
[0015] This utility model discloses a special double-layer quilt cover, which is a cover made of sewn fabric. The cover includes a standard quilt cover, an outer quilt cover, and an inner quilt cover. The standard quilt cover, the outer quilt cover, and the inner quilt cover are interconnected in the longitudinal direction. The cover has an opening and a movable connecting device for closing the opening.
[0016] In the aforementioned double-layered duvet cover, the fabrics of the outer duvet cover, inner duvet cover, and standard structure duvet cover are integrally and continuously arranged or sewn together in pairs along the length of the duvet cover. The left and right sides of the outer duvet cover, inner duvet cover, and standard structure duvet cover are respectively closed, and the tail end of the standard structure duvet cover has a transverse opening with a movable closing connection device at the opening.
[0017] In the aforementioned double-layered duvet cover, the fabrics of the outer duvet cover, the inner duvet cover, and the standard structure duvet cover are integrally and continuously arranged or sewn together in pairs along the length of the duvet cover. At least one side of the left and right sides of the outer duvet cover, the inner duvet cover, and the standard structure duvet cover each have an interlocking opening, and each opening is equipped with a movable closing device.
[0018] This utility model relates to another special cover for a double-layered quilt cover, which is a rectangular cover made of sewn fabric. The cover includes a flip-up cover and a main cover, which are continuously or connected from left to right along their length. The flip-up cover is closed at its left end, and its length is equivalent to the length of the double-layered quilt cover head. It flips over and fits into the space between the outer and inner layers of the double-layered quilt cover. The main cover is the same length as the double-layered quilt cover itself, and it fits over the outer surface of the double-layered quilt cover. A horizontal opening is provided at the right end, and a movable closing connecting device is provided at the opening. Movable connecting devices are provided at key parts of the cover.
[0019] This utility model discloses a double-layered comforter assembly, comprising a dedicated double-layered comforter cover and a double-layered comforter core. The double-layered comforter core is composed of multiple layers of comforter core material, wherein the main body typically consists of multiple layers of comforter core material stacked and quilted together to form a single-layer structure, while the double-layered comforter head consists of multiple layers of comforter core material stacked and quilted together to form a double-layer structure. The dedicated comforter cover and the double-layered comforter core are each equipped with corresponding movable connecting devices. The double-layered comforter core is fitted inside the dedicated comforter cover and connected and fixed by the movable connecting devices to form the double-layered comforter assembly.
[0020] The double-layered quilt headboard of this utility model has the following beneficial effects:
[0021] 1. Because of the double-layered duvet cover, the inner layer can completely cover the chest and abdomen. Hands and arms can be placed on the outside of the inner layer and pressed firmly to ensure tight coverage of the chest and abdomen. The hands and arms are positioned between the inner and outer layers, within the area covered by the outer layer, thus ensuring warmth for the chest and abdomen while preventing the hands and arms from getting cold.
[0022] 2. The double-layered blanket has openings on both sides, allowing arms to be extended from the side when used as a nursing blanket for intravenous drips or other treatments and tests. The outer layer can be easily lifted. This avoids the need for coordination of the hand, arm, and shoulder when extending the arm with a regular blanket, preventing the chest and abdomen from getting cold due to gaps between the arm and the blanket. Because the arm is between the inner and outer layers, it provides natural coverage, allowing the hand to remain covered during IV drips without being exposed outside the blanket.
[0023] 3. Because the arms are positioned between the inner and outer layers, arm movements do not affect the tightness of the chest and abdomen coverage, thus facilitating the operation of medical staff during treatment and nursing care, and making it easier for family members and patients to shake hands and communicate. Protective covers or pads can also be added to the outer layer to prevent the main body of the blanket from soiling when the patient eats or vomits, and these covers or pads do not affect the normal use of the nursing blanket.
[0024] 4. When ordinary people use the quilt of this utility model, the inner quilt covers the chest and abdomen. When the hands are placed between the inner and outer quilts, the hands can be relatively free. They can play games, use their mobile phones, etc. while lying in bed. At the same time, part of the arms are still covered by the outer quilt to prevent the arms from getting cold.
[0025] 5. This utility model's special duvet cover can be properly fitted onto the outer surface of a double-layered duvet cover and the inner surfaces of both the outer and inner duvet layers, effectively preventing dirt from getting on the duvet surface. It is also easy to remove and wash. Using existing commercial duvet inserts and this special duvet cover, a double-layered duvet cover can be easily assembled. Attached Figure Description

[0034] The structure of the double-layer quilt cover and special quilt cover of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings and specific embodiments are for illustrative purposes only and are not intended to limit the scope of protection.
[0035] Example 1: As Figure 1 , 2 and Figure 3 As shown, this embodiment is a double-layered quilt head, wherein the main body of the quilt is still a traditional rectangular structure, including a double-layered quilt head 100 and a normal main body 200. The double-layered quilt head 100 is a double-layered quilt body structure, consisting of an outer quilt body 102 and an inner quilt body 101. Each quilt body has the inner and outer fabrics of a normal quilt and a quilt core wrapped within the fabric. The two quilt bodies are independently positioned at the quilt head. The normal main body 200 is composed of a normal-structure quilt body 201, which is also a normal quilt body structure consisting of a quilt core and fabric, having the inner and outer fabrics of a normal quilt and a quilt core wrapped within the fabric, and is located at the back of the quilt. The rear ends of the outer quilt body 102 and the inner quilt body 101 are integrated with the front end of the quilt body 201 of the normal main body 200. The normal-structure quilt body 201, the outer quilt body 102, and the inner quilt body 101 are all structures consisting of a quilt core wrapped with double-layered fabric.
[0036] Specifically, in this embodiment, the double-layered quilt cover is composed of an outer fabric 16, an outer quilt core 15, an outer lining 14, an inner lining 13, an inner quilt core 12, and an inner fabric 11, arranged sequentially from top to bottom. The outer fabric 16, outer quilt core 15, inner quilt core 12, and inner fabric 11 all extend along the entire length of the double-layered quilt cover section 100 and the main body section 200, forming a continuous, integrated structure. The outer lining 14 and inner lining 13 are only located at the head of the double-layered quilt 100, and their lengths correspond to the head of the double-layered quilt.
[0037] At the position of the main body 200, the comforter insert is composed of the back of the outer comforter insert 15 and the back of the inner comforter insert 12, which means it is a combined comforter insert made of two layers. The thickness of the combined comforter insert is the thickness of the two layers after they are bonded together, that is, the thickness of the comforter insert in the main body is the same as the total thickness of the two layers in the head of the double-layer comforter insert. The comforter insert material used is cotton, silk, or fiber cotton, and the two layers can be tightly bonded together to form a comforter insert that is not easy to separate. The upper surface of the combined comforter insert is covered by the back of the outer fabric 16, and the lower surface of the combined comforter insert is covered by the back of the inner fabric 11. After edge sealing and quilting, the structure of the main body 201 is formed.
[0038] At the head 100 of the double-layer quilt, the front part of the outer quilt core 15 is the quilt core part of the outer quilt body 102. The front part of the outer fabric 16 covers the front part of the outer quilt core 15 from the upper surface, and the outer lining 14 covers the front part of the outer quilt core 15 from the lower surface. The edge sealing and quilting form the outer quilt body 102.
[0039] Similarly, at the head of the double-layer quilt 100, the front part of the inner quilt core 12 is the quilt core part of the inner quilt body 101, the front part of the inner fabric 11 covers the front part of the inner quilt core 12 from the bottom surface, the inner lining 13 covers the front part of the inner quilt core 12 from the top surface, and the edge sealing and quilting form the inner quilt head 101.
[0040] In the above structure, the outer fabric 16, inner fabric 11, outer quilt core 15, and inner quilt core 12 are all continuously arranged along the length of the quilt, while the outer lining 14 and inner lining 13 are respectively positioned at the head of the quilt 100. After assembly, the double-layered quilt head 100 and the normal main body 200 are simply separated by quilting thread 103. The quilting thread 103 horizontally sews the outer fabric 16, outer quilt core 15, outer lining 14, inner lining 13, inner quilt core 12, and inner fabric 11 together, thus forming an integrated connection between the double-layered quilt head 100 and the normal main body 200, resulting in a smooth transition.
[0041] like Figure 2 As shown, the outer layer of the double-layered quilt head is quilted and edge-sealed to form an independent quilt body 102, and the inner layer of the quilt head is quilted and edge-sealed to form an independent inner quilt body 101. Simultaneously, the outer quilt body 102 and the inner quilt body 101 of the double-layered quilt head are quilted together with the normal structural part 200 via quilting lines 103, forming a continuous, integrated structure. This creates an open space structure where the inner quilt body 101 and the outer quilt body 102 of the double-layered quilt head are quilted together with the normal structural part 200 at the rear end, and open at the front end and on both sides.
[0042] The double-layered quilt head described above, because the inner and outer fabrics and inner and outer fillings of the double-layered quilt head 100 and the regular main body 200 are all integrally and continuously designed, allows for a consistent overall thickness between the double-layered quilt head 100 and the regular main body 200. In other words, the total thickness of the double-layered quilt head 100 is essentially the same as the thickness of the regular main body 200; the difference is only due to the two lining layers at the double-layered quilt head 100 and can be ignored. Therefore, it will not affect folding and storage.
[0043] In the aforementioned quilts, the length of the head section of a double-layered quilt can be between one-quarter and one-third of the total quilt length, roughly the sum of the user's arm and hand length, to accommodate different arm lengths. The exact length may vary depending on the user group. The width of the head section of the double-layered quilt is the same as the overall quilt width to avoid affecting storage and folding.
[0044] In practical use, the inner layer 101 of this blanket covers the chest and abdomen. Arms can then be placed on the outside of the inner layer 101 to press it down. At this time, the arms are positioned between the inner and outer layers and can extend from the side, allowing for free movement. Arm movement does not affect the tightness of the coverage of the chest and abdomen, preventing them from getting cold. This is more conducive to administering IV drips, undergoing examinations, or using other instruments. It also allows relatives to shake hands with the patient and comfort them. If the inner layer is further compressed longitudinally, the upper layer can be placed over the arms and shoulders to prevent them from getting cold.
[0045] The outer quilt core 15 and inner quilt core 12 mentioned above are not necessarily composed of two layers of quilt core material. They can be composed of multiple layers of quilt core material. For example, the inner quilt core 12 can use two 2 cm thick cotton cores, and the outer quilt core 15 can use one 2 cm thick cotton core, which can form a typical 6 cm cotton core for the main body, a 2 cm cotton core for the outer quilt body, and a 4 cm cotton core for the inner quilt body. The reverse is also true. Similarly, other types of materials can also be used as quilt cores. The thickness of the inner and outer quilt cores can be equal or unequal, and there is no need to be precise about the concept of inner and outer layers. That is, the inner and outer layers in the above description are not absolute and can be converted into each other.
[0046] Example 2: In this example, the length of the outer quilt 102 is appropriately increased. For example, the length of the outer quilt 102 is increased to 15-30 cm greater than that of the inner quilt 101 in the direction of the quilt head. This can achieve natural coverage of the arms and shoulders without compressing the inner quilt 101.
[0047] Example 3: As Figure 4 As shown, in this embodiment, a movable connecting device is provided between the outer quilt body 102 and the inner quilt body 101 of the double-layer quilt head 100. For example, an invisible zipper 104 can be used. The invisible zipper 104 can lock and close both sides, which is beneficial for folding and storage. Of course, the movable connecting device can also be a button, Velcro, connecting strap, etc.
[0048] Example 4: In this example, the double-layered quilt head 100 and the regular main body 200 are no longer integrated. Instead, an outer quilt body 102, an inner quilt body 101, and a regular structural quilt body 201 are fabricated separately, and then the three are horizontally sewn together using a sewing connection line 103. This structure is simpler to manufacture, but the connection feels overly stiff and not as smooth as a continuous, integrated design. However, it basically achieves the purpose of this utility model.
[0049] The manufacturing process of the aforementioned utility model product can be as follows: The materials are laid out sequentially from the bottom layer, for example, first laying the inner fabric 11, then the inner quilt core 12, then laying the inner lining 13 and outer lining 14 at the double-layer quilt head 100 position, followed by the outer quilt core 15 and outer fabric 16. After aligning the layers, a horizontal quilting line 103 is made to sew the layers together. Then, the edges are sealed and quilted to create the double-layer quilt head of this utility model.
[0050] The structure of the double-layered quilt head of this invention is also applicable to blankets and other similar products that have quilt functions, and can also be used in sleeping bag products.
[0051] Given that this utility model product is a novel design, it is necessary to design a special duvet cover specifically for double-layered duvet covers to protect the duvet itself from getting dirty and to make the duvet cover easy to remove and wash. The following examples illustrate the structure of the special duvet cover.
[0052] Example 5: Figure 5 , Figure 6 The image shows the structure of a special duvet cover designed specifically for the aforementioned double-layered duvet cover. Figure 5 This is a side-view sectional structural diagram, illustrating a special duvet cover for a double-layered duvet cover according to this utility model. The special duvet cover is a sewn fabric cover body, divided into three interconnected spatial structures. Cover body 41 contains a space 42 accommodating the main body 200 of the double-layered duvet cover; cover body 51 contains a space 52 accommodating the outer layer 102 of the double-layered duvet cover; and cover body 61 contains a space 62 accommodating the inner layer 101 of the double-layered duvet cover. The fabric between the three interconnected space bodies is either continuous or connected in pairs along its length. Fixing devices are installed at four key points (1-4) on the inner side of the cover body, corresponding to the parts of the double-layered duvet cover, to secure the duvet and cover together and prevent discomfort. These fixing devices can be snaps, Velcro, connecting straps, buttons, etc.
[0053] like Figure 6As shown, openings are provided on the sides of the duvet cover for attaching or removing it. These openings are located on the sides of the duvet cover and are respectively: a side opening 43 for the main body, a side opening 53 for the outer duvet cover, and a side opening 63 for the inner duvet cover. These three openings align with the boundary between the double-layer duvet head 100 and the main body 200, and each opening is fitted with a concealed zipper as a closure device. In this embodiment, the openings are located on the sides, corresponding to the respective parts of the double-layer duvet head, for easy attachment and removal of the duvet cover. Of course, the openings and movable connecting devices could also be located at the end of the single-layer main body or other convenient locations, as long as they allow for insertion and removal.
[0054] Example 6: This example is also a special duvet cover for double-layered duvet covers, such as... Figure 7 As shown, a rectangular cover is provided, made of double-layered fabric. Three sides of the rectangular cover are sewn closed, with an opening only at the rightmost end. From left to right, it is defined as a flip cover 7 and a main cover 8, which are consecutively arranged. The left end of the flip cover 7 is closed, and the right end of the main cover 8 is open, with a zipper 9 at the opening for a movable closure connection. The top and bottom sides of the cover are closed, and its overall length is approximately the total length of the double-layered quilt cover plus the length of the double-layered quilt head. The main cover 8 is approximately the same length as the double-layered quilt cover, and the flip cover 7 is approximately the same length as the double-layered quilt head 100. In use, the main cover 8 is normally placed on the outer surface of the double-layered quilt cover, and the flip cover 7 is folded inwards and placed on the inner surface between the outer quilt body 102 and the inner quilt body 101 of the double-layered quilt cover. After the cover is put on, the double-layered quilt head becomes a double-layered quilt with closed sides.
[0055] like Figure 8 As shown, in this embodiment, an operating hand hole 10 can also be opened at the end of the left closed end of the flip cover 7. The purpose of opening the operating hand hole 10 is to facilitate the hand to reach into the cover from the outside and connect the movable connecting device inside the cover with the movable connecting device at the double-layer connection of the double-layer quilt head to fix the quilt cover and the quilt.
[0056] The aforementioned double-layered comforter can also be achieved by combining a dedicated comforter core and a dedicated comforter cover. First, a dedicated comforter core is manufactured, consisting of two or more finished comforter cores. Since the finished comforter cores have already undergone material processing and even quilting, the outer surface of the comforter core material is already sealed, allowing it to be directly fitted inside the comforter cover to form a comforter. The shaped comforter cores are stacked in two or more layers, and the double or multiple layers of the main body are quilted and cured, stitching the multiple layers together to form a single-layer structure. Then, the shaped comforter cores of the double-layered comforter head are divided into two layers and quilted and cured separately, thus forming the dedicated comforter core for the double-layered comforter head. Next, the dedicated comforter cover is fitted onto the dedicated comforter core using the same method as the dedicated comforter cover, and the corresponding movable connecting devices are connected to form the structure of this combined double-layered comforter head.
