Description
Technical Field
[0001] The utility model belongs to the technical field of medical care, and in particular relates to a gravity blanket. Background Art
[0002] A comfortable sleeping environment can relieve people's anxiety and improve their sleep quality. Existing quilts or blankets basically only have the function of keeping warm, so they cannot soothe people's emotions through deep contact pressure and enable people to get higher sleep quality.
[0003] The key feature of a weighted blanket is that it applies a weight exceeding 10% of one's body weight to the body, thereby relieving anxiety, relaxing the mind, and improving sleep quality for those suffering from insomnia. Research demonstrating that weighted blankets can improve sleep and reduce stress has been scientifically validated, and they hold enormous market potential. The choice of filling material is crucial to a weighted blanket's performance. Currently, common weighted blankets on the market typically use weighting beads such as glass sand, glass beads, or ceramic beads to achieve this weighting function. However, in practice, these blankets lack air permeability, creating a stuffy feeling and often being unsuitable for temperatures above 25°C. Furthermore, with repeated washings, the weighting beads can easily break through the fabric and shift from their original position, making uniform weight distribution impossible. In applications where glass sand is used, since its diameter is typically only 0.5mm to 0.8mm, there is a safety risk of leakage over time, potentially causing ingestion by children or pets. Furthermore, the commonly used weighting beads, such as glass sand, glass beads, or ceramic beads, are difficult to recycle. When a gravity blanket is discarded, it inevitably pollutes the environment and may even pose potential risks. While some have proposed using cotton or other down as a replacement for weighting beads, these materials have the disadvantage of being lightweight, which would increase the space required for the blanket and the cost.
[0004] Furthermore, existing weighted blankets are difficult to adjust. In practice, due to individual differences, people have varying requirements for the amount of force and weight applied to different areas of the blanket. Therefore, it is crucial to design a weighted blanket that can adjust the weight of different areas of the blanket to meet diverse sleep needs. Furthermore, since most existing weighted blankets are integrated, subsequent cleaning and maintenance are also pressing issues. Utility Model Content

DETAILED DESCRIPTION
[0030] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples provided are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are in a very simplified form and are not in exact proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention.
[0031] like Figure 1 As shown, this embodiment provides a gravity blanket, including a gravity blanket body 1, in which a counterweight layer 11 is detachably provided. The counterweight layer 11 is a mesh member, so that the counterweight layer can be conveniently removed from the gravity blanket body to clean the part of the gravity blanket body except the counterweight layer.
[0032] The counterweight layer 11 in the above technical solution is a knotless woven mesh or a metal chain mesh made of ropes, so that the counterweight layer has a mesh structure, which can avoid the counterweight layer from affecting the air permeability of the gravity blanket.
[0033] The knotless woven mesh described in the above technical solution is woven from a rope made of cotton fiber, linen fiber or polyester fiber (the rope can be a slightly thicker rope, specifically a rope with a diameter of about 0.5 cm. Of course, the rope can also be made of other fibers with higher density, such as a rope made of core-filled yarn), or the metal chain mesh (similar to chain mail, which is made of multiple rings buckled together) is made of aluminum alloy, copper, iron or stainless steel (the rings of the metal chain mesh can be wrapped with a layer of plastic sheath to avoid the noise of metal collision). It has a simple structure and the density of the counterweight layer is high, which is conducive to improving its counterweight effect.
[0034] The weight of the counterweight layer 11 in the above technical solution is 1-6 kg / m 2 (1kg / m 2 , 2kg / m 2 3kg / m 2 , 4kg / m 2 , 5kg / m 2 and 6kg / m 2 Any value or the corresponding range between any two values in the range), so that its weight balancing effect is better.
[0035] The counterweight layer 11 in the above technical solution includes a plurality of square counterweight areas 111, and the plurality of counterweight areas 111 are spliced together to form the counterweight layer 11, and the sides of two adjacent counterweight areas 111 close to each other can be detachably connected. In this way, the number of counterweight areas can be adjusted as needed so that a notch can be formed on the counterweight layer, thereby forming a thin area at the notch of the gravity blanket body.
[0036] In the above technical solution, any two adjacent counterweight areas 111 are detachably connected on their adjacent sides via a first connector 112 , so that multiple counterweight areas can be connected into pieces via the first connector to complete the splicing of the counterweight layer.
[0037] In the above technical solution, the first connecting member 112 is preferably a lace, which has a simple structure and makes it easy to splice adjacent weight areas (with Figure 2 For example, Figure 2 Multiple weight zones in Figure 2 There are ties at the circles marked in the middle, which makes it easy to splice multiple weight areas).
[0038] like Figure 2 As shown, in the above technical solution, the plurality of counterweight areas 111 are respectively a first counterweight area 111a, a second counterweight area 111b, a third counterweight area 111c and four fourth counterweight areas 111d. The widths of the first counterweight area 111a, the second counterweight area 111b and the third counterweight area 111c are consistent in width direction. The lengths of the first counterweight area 111a and the second counterweight area 111b in the length direction are shorter than the length of the third counterweight area 111c in the length direction. The length of the fourth counterweight area 111d in the front-to-back direction is half of the length of the gravity blanket body 1. The first counterweight area 111a, the second counterweight area 111b, and the third counterweight area 111c are arranged in sequence along the front-to-back direction, and the two sides are aligned and connected to each other in sequence to form a middle part. Two fourth counterweight areas 111d are arranged in sequence along the front-to-back direction on both sides of the middle part. The two fourth counterweight areas 111d on the same side are connected at one end close to each other, and the sides close to the middle part are connected to the middle part to assemble into the counterweight layer 11. Its structure is simple, which makes it easy to assemble multiple counterweight areas, and the corresponding counterweight areas can be removed as needed to form a light and thin area on the gravity blanket body.
[0039] In the above technical solution, the weight of the first counterweight area 111a, the second counterweight area 111b and the fourth counterweight area 111d are respectively 0.05-0.1 of the total weight of the counterweight layer 11, and the weight of the third counterweight area 111c is 0.5-0.7 of the total weight of the counterweight layer 11, so that the area of the third counterweight area is the largest and corresponds to the position of the user's lower body. Preferably, the first counterweight area and the second counterweight area account for about 3 / 32 of the total weight of the counterweight layer, and the fourth counterweight area is It accounts for about 1 / 16 of the total weight of the counterweight layer, and the third counterweight area accounts for about 9 / 16 of the total weight of the counterweight layer (the size of the gravity blanket in this embodiment can be 2m×2m, and the area of each counterweight area accounts for the area of the counterweight layer and its weight accounts for the weight of the counterweight layer. At this time, the width of the first counterweight area and the second counterweight area are both 0.25m, and their length is 1.5m. The length of the fourth counterweight area is 1m and the width is 0.25m. The length and width of the third counterweight area are both 1.5m).
[0040] The gravity blanket body 1 in the above technical solution also includes two fiber surface layers 12 and two filling surface layers 13. The two filling surface layers 13 are stacked between the two fiber surface layers 12, and the counterweight layer 11 is sandwiched between the two filling surface layers 13. In this way, the entire gravity blanket body has good air permeability and good comfort.
[0041] like Figure 3 As shown, in this embodiment, the fiber surface layer and the filling surface layer that are bonded to each other, as well as the two filling surface layers, can be detachably connected by a second connecting member 14. The second connecting member 14 can be a Velcro. Multiple second connecting members 14 can be set at the edges and middle parts between the fiber surface layer and the filling surface layer that are bonded to each other (a circle of second connecting members 14 can be set at the edge of the side where the two are close to each other, and multiple second connecting members 14 can be evenly spaced in the middle part between the two). Similarly, the two filling surface layers can also be set in a similar manner, except that the second connecting members 14 in the middle of the two can be bonded through the mesh of the counterweight layer.
[0042] In this embodiment, both the fiber surface layer and the filling surface layer may be breathable blankets made of cotton fiber material.
[0043] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
