Description

Technical Field

[0001] This utility model relates to the field of gravity blanket technology, and particularly to gravity blankets. Background Technology

[0002] One type of deep pressure therapy involves placing a weighted blanket on the body to apply pressure, creating a sense of security similar to being hugged or wrapped. Conventional fabrics don't provide enough pressure to effectively deliver deep pressure therapy when placed on the body; therefore, additional material is usually needed to provide weight. Typical deep pressure therapy blankets are weighted blankets made of multiple layers of fabric, with additional weight placed between these layers. These additional weights typically include, for example, small plastic balls or spheres, glass beads, sand, gravel, linked chains, etc. The additional weight is usually placed in units within the blanket. For example, additional weight is often placed in the form of secondary patches, which are sewn or stitched together to hold the weight.

[0003] However, the need for external weights comes with several drawbacks. For example, external weights restrict the breathability of the blanket. The weights and multiple layers of fabric reduce the natural airflow through the blanket. This makes it particularly difficult to regulate an individual's body temperature when the blanket is placed on them. Furthermore, external weights tend to move and / or shift within the blanket. This substantially impairs the equal, uniform, and continuous weight distribution required for deep pressure therapy. Moreover, external weights often cause the blanket to become too thick and less flexible, preventing it from naturally conforming to the shape of the person lying beneath it and thus reducing the surface contact area for deep pressure therapy.

[0004] To address the current problems of poor breathability, uneven pressure, and difficulty in bending of gravity blankets, it is necessary to conduct further research on gravity blankets. Utility Model Content

[0005] The purpose of this invention is, on the one hand, to provide a gravity blanket to solve the problems of poor breathability, uneven pressure and difficulty in bending of current gravity blankets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gravity blanket includes a blanket body woven from coarse yarn, the coarse yarn including a flexible mesh body extending along the axial direction of the coarse yarn, and the flexible mesh body having breathable mesh holes.

[0008] The thick wire also includes an air channel. The flexible mesh body is arranged in a ring shape to form the air channel, and the air channel is connected to the outside through the breathable mesh.

[0009] The flexible mesh body is woven from fine threads.

[0010] The flexible mesh body is formed by the layers of fine threads stacked and surrounding each other to form a layered structure.

[0011] During the process of layering and wrapping, the thin wires form multiple connecting knots between adjacent wrapping segments, which connect the thin wires of adjacent wrapping segments to each other.

[0012] The thin wire includes a sleeve extending from a looping segment of the thin wire and a receiving segment extending from an adjacent looping segment of the thin wire, the sleeve being fitted onto the receiving segment to form the connection knot.

[0013] The fine threads are shaped into the flexible mesh body by a circular knitting machine.

[0014] The fine thread is crocheted by 6 to 12 hooks to form the flexible mesh body.

[0015] The flexible mesh body is woven from a single strand of the fine thread.

[0016] The single strand of fine thread is fed into the circular knitting machine through 6 hooks to obtain a 1-meter thick thread weighing 6g.

[0017] The single strand of fine thread is fed into the circular knitting machine through 12 hooks to obtain a thick thread weighing approximately 13g per meter.

[0018] The flexible mesh body is woven from two strands of the aforementioned fine threads.

[0019] The double-stranded fine thread is fed into the circular knitting machine through 6 hooks to obtain a 1-meter thick thread weighing 13g.

[0020] The double-stranded fine thread is fed into the circular knitting machine through 12 hooks to obtain a thick thread weighing approximately 25g per meter.

[0021] The thick yarn is woven into the blanket body by a flat knitting machine.

[0022] The blanket body can have a variety of weaving patterns.

[0023] The blanket body includes a main body and a surrounding part, the surrounding part being woven around the main body.

[0024] The main body can have various woven patterns, and the enclosure can have various woven patterns.

[0025] The advantage of this technical solution lies in the use of a blanket body woven from coarse yarns, including a flexible mesh body that extends along the axial direction of the yarns and forms breathable mesh openings. Because the coarse yarns themselves are relatively heavy, there is no need to use additional weighting materials, avoiding the problem of uneven pressure. Furthermore, the inclusion of a flexible mesh body in the coarse yarns provides both softness and good breathability, solving the current problems of poor breathability, uneven pressure, and difficulty in bending in gravity blankets.

[0035] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0036] In this embodiment, please refer to Figures 1 to 2 A gravity blanket includes a blanket body 1, which is woven from coarse yarn 2. The coarse yarn 2 includes a flexible mesh body 21, which extends along the axial direction of the coarse yarn 2 and has breathable mesh holes 211.

[0037] By employing a blanket body woven from coarse yarns, including a flexible mesh extending along the axial direction of the yarns and forming breathable pores, the blanket achieves its purpose. Because the coarse yarns themselves are relatively heavy, there is no need for additional weighting materials, thus avoiding uneven pressure. Furthermore, the inclusion of a flexible mesh in the yarns provides both softness and excellent breathability, solving the current problems of poor breathability, uneven pressure, and difficulty in bending in gravity blankets.

[0038] In this embodiment of the utility model, please refer to Figure 2 The thick thread 2 also includes an air channel 22. The flexible mesh body 21 is arranged in a ring shape to form the air channel 22, and the air channel 22 is connected to the outside through the breathable mesh 211. Through the above structural arrangement, an axially extending air channel is formed at the center of the thick thread, so that air can be connected inside and outside the ring-shaped thick thread, further improving the breathability of the product.

[0039] In this embodiment of the invention, the flexible mesh body 21 is woven from fine threads 3. The coarse thread 2 may include other auxiliary parts besides the flexible mesh body 21, or it may only include the flexible mesh body 21. That is, the coarse thread 2 can be directly woven from the fine threads 3. The gravity blanket uses coarse thread 2 directly woven from fine threads 3, which increases gravity and easily achieves uniform pressure. It also possesses breathability and softness, and the simplification of materials and processes helps improve production efficiency. The flexible mesh body 21 can be woven from single-strand fine threads, double-strand fine threads, or even three-strand or four-strand fine threads.

[0040] The flexible mesh body 21 is formed by the thin wires 3 stacked and surrounded to form a stacked structure.

[0041] Specifically, during the layering and wrapping process, the fine wires 3 form multiple connecting knots 214 between adjacent wrapping segments. The connecting knots 214 connect the fine wires 3 of adjacent wrapping segments to facilitate the weaving of the flexible mesh body.

[0042] Furthermore, the thin wire 3 includes a sleeve portion 212 extending from a loop segment of the thin wire 3 and a receiving portion 213 extending from an adjacent loop segment of the thin wire 3. The sleeve portion 212 is fitted onto the receiving portion 213 to form the connecting knot 214. Of course, multiple connecting knots are formed between the upper and lower layers of thin wires to facilitate a stable connection between the upper and lower layers of thin wires.

[0043] As one implementation method, please refer to Figure 3 and Figure 4 Fine thread 3 is woven by a circular knitting machine to form a flexible mesh body 21. Circular knitting machines are suitable for sewing circular fabrics such as clothing, and are generally used for sewing heavier, thicker canvas, leather, and other special fabrics. Circular knitting machines can not only sew flat surfaces, but also various complex curves and arcs, including diamonds, spheres, and rings. The knitting principle of a circular knitting machine involves knitting through a cylindrical needle bed. The needles are fixed to the needle bed, and the yarn is fed in through a yarn guide. As the needles rotate, loops are formed.

[0044] In this embodiment of the utility model, please refer to Figure 3 and Figure 4 The circular knitting machine has a cylindrical syringe 6 and an outer cylinder 7 surrounding the syringe 6. The outer cylinder 7 has a thread inlet 5 at its top and a thread inlet arm (not shown) on one side. A needle groove 61 is formed on the outer circumferential surface of the syringe 6, and the needle groove 61 is angled evenly on the outer circumferential surface of the syringe 6. The needle groove 61 is used to accommodate a hook 4, which is fixed to the bottom of the needle groove 61. The hook 4 has a hook portion 41 at its end facing away from the bottom of the needle groove 61. The hook portion 41 has an open state and a closed state; for example, a locking device can be provided in the hook portion 41 (the specific structure of the hook is a conventional structure, in...). Figure 4(Not shown in detail in the text) When the hook section 41 is in the open state, the locking device opens to allow the thread 3 originally housed in the hook section 41 to come out of the hook section 41. When the hook section 41 is in the closed state, the locking device closes to prevent the thread 3 from coming out of the hook section 41. The hook needle 4 can move axially, and the outer cylinder 7 can rotate relative to the needle cylinder 6. For example, a drive belt can be provided on the outer circumference of the outer cylinder 7. The drive belt drives the outer cylinder 7 to rotate under the drive of the drive device, while the needle cylinder 6 remains stationary. During operation, the thread 3 enters the circular knitting machine through the thread inlet 5 opened at the top of the outer cylinder 7, and enters the needle cylinder 6 through the thread inlet arm. The hook needle 4 housed in the needle groove 61 hooks and knits to form a flexible mesh body 21. Specifically, the outer cylinder 7 can be driven to rotate, causing the thread 3 to rotate around the needle cylinder 6, so that the thread 3 can contact the hook 4 on the needle cylinder 6 in sequence. The hook 4 inside the needle cylinder 6 moves up and down in sequence. When the hook 4 moves upward (i.e. moves away from the bottom of the needle groove 61, at which time the hook part 41 is in the open state), the thread that was originally wrapped around the hook part 41 comes out of the hook part 41 and enters the needle handle of the hook 4, and completes a new hooking operation at the hook part 41. When the hook 4 moves downward (i.e. moves towards the bottom of the needle groove 61, at which time the hook part 41 is in the closed state), the newly hooked thread sinks below the thread located at the needle handle, so that the thread that was originally located at the needle handle wraps around the newly hooked thread and comes out of the needle handle, forming a flexible mesh body 21, and completing the weaving operation. The flexible mesh body 21 of this utility model is formed by hooking fine thread 3 with a circular knitting machine. This not only ensures the weight of the thick thread 2, but also improves the breathability and comfort of the weighted blanket due to the formation of a uniform and breathable mesh structure. In addition, the production process is highly automated and simple, and there is no need to manufacture interlayers or add other weighted materials, which greatly improves production efficiency.

[0045] In this embodiment of the invention, the weight per unit weight of the coarse thread 2 can be controlled by controlling the number of strands of the fine thread 3 and the number of hooks 4 on the circular knitting machine. The fine thread 3 can be crocheted with 6 to 12 hooks 4 to form a flexible mesh body 21, and a corresponding number of connecting knots can be formed between the upper and lower layers of fine thread depending on the number of hooks. The fine thread 3 can be single-stranded or double-stranded. The more hooks 4 and the more strands, the denser the flexible mesh body 21 of the coarse thread 2, and the higher the weight per unit weight of the coarse thread 2. Therefore, it can meet the user's more precise gravity requirements for the weighted blanket.

[0046] In one embodiment, the flexible mesh body 21 is woven from a single strand of fine yarn 3. Further, the single strand of fine yarn 3 is fed into a circular knitting machine through 6 crochet hooks 4 to obtain a thicker yarn 2 weighing 6 g / meter. Further, the single strand of fine yarn 3 is fed into a circular knitting machine through 12 crochet hooks 4 to obtain a thicker yarn 2 weighing approximately 13 g / meter. When lower weight is required, a process using fewer single strands of fine yarn 3 and fewer crochet hooks 4 can be used to produce the thicker yarn 2.

[0047] In one embodiment, the flexible mesh body 21 is woven from double-stranded fine yarn 3. Further, the double-stranded fine yarn 3 is fed into a circular knitting machine through 6 crochet hooks 4 to obtain a thicker yarn 2 weighing 13g / meter. Further, the double-stranded fine yarn 3 is fed into a circular knitting machine through 12 crochet hooks 4 to obtain a thicker yarn 2 weighing approximately 25g / meter. When a greater weight is required, a process using more double-stranded fine yarn 3 and a larger number of crochet hooks 4 can be used to produce the thicker yarn 2.

[0048] In this embodiment of the utility model, reference is made to Figure 5 The thick yarn 2 is knitted by a flat knitting machine to form the blanket body 1. A flat knitting machine is a high-speed sewing machine suitable for sewing clothing, bedding, curtains, bags, etc. Because of its high speed, it allows for faster sewing and is suitable for production line operations or long-term work. The knitting principle of a flat knitting machine is achieved by the reciprocating motion of the knitting head, equipped with a loop-forming mechanism, on the needle bed, driving the needles to move up and down in the needle grooves. In addition to the blanket body 1, a gravity blanket may include other auxiliary parts, or it may only include the blanket body 1. The blanket body 1 offers a variety of knitting patterns to choose from. When knitting the blanket body 1 using a flat knitting machine, various knitting patterns can be incorporated into the machine, provided directly from external devices (such as external storage devices), obtained through networking, or even customized by the user.

[0049] In this embodiment of the utility model, the blanket body 1 can be configured to include a main body and an enclosing part, with the enclosing part woven around the main body to further enhance the aesthetic effect of the gravity blanket. The main body and the enclosing part each offer a variety of weaving patterns to choose from. By providing the main body and the enclosing part, and by offering multiple weaving patterns for both, the user's requirements for customizing the appearance of the gravity blanket can be better met.
