Technical Field
[0001] This utility model relates to the field of textile products, and in particular to a multifunctional wool sleeping bag with a detachable pillow. Background Technology
[0002] Currently, sleeping bags are widely used as a sleep protection tool. Traditional sleeping bags provide users with a sufficiently good sleeping space, and the limited space provides good sleep protection for users, making them convenient to use.
[0003] Related technology can be found in Chinese Patent No. CN217987219U, which discloses a thermal fleece-lined sleeping bag, comprising: a sleeping bag body, which includes a mattress and a cover, both of which are sheet structures. One side of the cover is connected to one side of the mattress, and the other side of the cover is detachably connected to the other side of the mattress. The sleeping bag body includes a waterproof layer and a thermal insulation layer, with a fleece liner layer disposed between the thermal insulation layer and the waterproof layer. This thermal fleece-lined sleeping bag effectively increases its warmth retention through the fleece liner layer.
[0004] Regarding the aforementioned technologies, the pillow and sleeping bag are fixedly connected, making it difficult for users to adjust and change the pillow according to their needs. Although some designs include detachable pillows, pillows are usually secured with Velcro, zippers, or buttons. Zippers can easily get stuck in the fabric, and button fastening is difficult to align when wearing gloves outdoors, making it inconvenient for users. Velcro is less prone to the same problems during use, but the application of existing Velcro is easily affected by the user's operation. If the user does not align the two Velcro straps before fastening them, the pillow will be tilted. Since the Velcro is usually located between the pillow and the sleeping bag, it is not easy to see when installing the pillow. Therefore, the pillow usually needs to be repeatedly adjusted to reach the preset position, which is not conducive to improving the ease of use of the sleeping bag. Utility Model Content
[0005] To improve the ease of use of sleeping bags, this application provides a multifunctional wool sleeping bag with a detachable pillow.
[0006] This application provides a multifunctional wool sleeping bag with a detachable pillow, employing the following technical solution:
[0007] A multifunctional wool sleeping bag with a detachable pillow includes a sleeping bag body with an internal chamber for accommodating a user. One end of the sleeping bag body is a backrest. A corresponding pillow is provided at the backrest. The pillow has a Velcro closure one, and the backrest has a Velcro closure two corresponding to the Velcro closure one. A guide is also provided between the pillow and the backrest for the Velcro closure one to be aligned with the Velcro closure two.
[0008] By adopting the above technical solution, the sleeping bag body provides a sleeping space for the user through the chamber. When the user moves the pillow, the guide aligns the pillow with the preset position on the backrest. At this time, Velcro 1 and Velcro 2 are facing each other. Pressing down on the pillow causes Velcro 1 and Velcro 2 to fully adhere, connecting the pillow to the backrest. The backrest supports and fixes the pillow, and the fixed pillow provides stable support for the user's neck and head. When the user pinches the guide and separates the pillow in a direction away from each other, Velcro 1 and Velcro 2 separate, thus separating the pillow from the backrest.

[0037] The present application will be further described in detail below with reference to all the accompanying drawings.
[0038] This application discloses a multifunctional wool sleeping bag with a detachable pillow.
[0039] Example 1
[0040] Reference Figure 1 A multifunctional wool sleeping bag with a detachable pillow 2 includes a pillow 2 and a sleeping bag body 1. The pillow 2 is used to support the user's neck. The sleeping bag body 1 has a cavity 15 for accommodating the user's sleep. A zipper 16 for opening and closing the cavity 15 is fixed on the outer surface of the cavity 15 along the length direction of the cavity 15. Wool felt 11 is detachably connected to the surface of the sleeping bag body 1, and a backing part 12 is provided at one end along the length direction. The pillow 2 is detachably connected to the backing part 12, and the pillow 2 can be square, round or other shapes. This embodiment uses a square pillow as an example for explanation.
[0041] The pillow 2 has a Velcro 23 attached to the side near the backrest 12. The backrest 12 has a Velcro 23 attached to the side near the backrest 12. In this embodiment, the Velcro 23 is hooked and the Velcro 23 is looped. The Velcro 23 is treated with a UV-resistant coating, which helps to reduce the probability of the Velcro 23 being affected by UV rays outdoors. The Velcro 23 is treated with silicone oil impregnation, which helps to reduce the probability of fiber breakage in the Velcro 23, thereby improving the service life of the Velcro 23 and the Velcro 23.
[0042] A guide is provided between the pillow 2 and the backrest 12. The guide includes a guide block 14, which is fixedly connected to the backrest 12. In this embodiment, the guide block 14 is connected to the backrest 12 by ultrasonic welding. The upper surface of the guide block 14 is in contact with the surface of the sleeping bag body 1, and a guide groove 141 is formed on the upper surface of the guide block 14 along its length. A magnetic strip 1411 is installed at the bottom of the guide groove 141, and a magnetic buckle 24 that matches the guide groove 141 is installed on the lower surface of the pillow 2. The guide groove 141 guides and fixes the magnetic buckle 24 through the magnetic strip 1411.
[0043] When the magnetic snap 24 is located within and engages with the guide slot 141, the first hook and loop fastener 23 is positioned directly above the second hook and loop fastener 13. At this time, when the user presses down on the pillow 2, the magnetic snap 24 inserts into and engages with the guide slot 141, and the first hook and loop fastener 23 engage with the second hook and loop fastener 13, thus connecting the pillow 2 to the preset position on the backrest 12. This improves the accuracy and stability of the connection between the pillow 2 and the backrest 12, ensuring stable support for the user's neck and enhancing the user experience.
[0044] When the user needs to remove the pillow 2 from the sleeping bag body 1, pinch the lower end of the guide block 14 and one end of the pillow 2 respectively, and then pull them in opposite directions. This will cause the magnetic buckle 24 to disengage from the guide slot 141 and the Velcro 1 23 to separate from the Velcro 2 13, thus separating the pillow 2 from the sleeping bag body 1 and improving the efficiency of removing the pillow 2.
[0045] Hook and loop fastener 23 is fixedly mounted with hook teeth 231 along the circumferential direction on its surface. The hook teeth 231 are trapezoidal and their diameter decreases from the direction of hook and loop fastener 23 to hook and loop fastener 13. The surface of hook and loop fastener 13 is provided with grooves 134 along the circumferential direction that correspond to the hook teeth 231. When hook and loop fastener 23 and hook and loop fastener 13 are bonded together, the hook teeth 231 are inserted into the grooves 134 and fit against the inner wall of the grooves 134. Hook and loop fastener 13 limits the lateral displacement of hook and loop fastener 23 through the grooves 134, which helps to improve the lateral tensile strength of hook and loop fastener 23 and hook and loop fastener 13.
[0046] Both Hook & Loop 1 23 and Hook & Loop 2 13 include an inner layer, a middle layer, and an outer layer. The outer layer is a waterproof base tape 133 made of nylon. The middle layer is a cushioning layer 132 made of high-elastic sponge. The inner layer is a backing 131 made of antibacterial fabric. These features help reduce the probability of Hook & Loop 1 23 and Hook & Loop 2 13 curling at the edges and growing mold, thus extending their service life and improving the user experience.
[0047] Hook and loop fastener 1 23 is fixedly connected to the pillow 2 by double stitching along the circumference, and hook and loop fastener 2 13 is fixedly connected to the backrest 12 by double stitching along the circumference. Both hook and loop fastener 1 23 and hook and loop fastener 2 13 are sealed with hot melt adhesive strips at the edges to achieve waterproof sealing, thereby making the pillow 2 and the backrest 12 stably connected and improving the connection stability between the pillow 2 and the backrest 12.
[0048] The pillow 2 has a fixed filling cavity 22 inside, and hidden zippers 21 are fixed on both sides of the pillow 2 along its length. The inner wall of the filling cavity 22 is fixedly installed with a dirt-proof layer 221. When the user is camping outdoors, he / she can put clothes, leaves and other items into the filling cavity 22 by unzipping the hidden zipper 21 to support the filling cavity 22 for temporary emergency support, which helps to improve the convenience of using the sleeping bag.
[0049] The implementation principle of a multifunctional wool sleeping bag with a detachable pillow in this application embodiment is as follows: the magnetic buckle 24 is inserted into the guide slot 141, the backrest 12 is fixed to the magnetic buckle 24 through the guide slot 141, and then the pillow 2 is fixed. Velcro 1 23 and Velcro 2 13 are glued together, and the hook teeth 231 are inserted into the corresponding grooves 134 to further fix the connection between the pillow 2 and the backrest 12, which helps to improve the connection stability between the pillow 2 and the backrest 12 and the convenience of using the sleeping bag.
[0050] Example 2
[0051] The difference between this embodiment and Embodiment 1 is that the guide includes a plurality of fluorescent dots 121.
[0052] A number of fluorescent dots 121 are evenly distributed on the backrest 12. The shape of the fluorescent dots 121 is the same as that of the pillow 2. When the user is camping outdoors at night, he / she can use the fluorescent dots 121 to determine the preset position on the backrest 12 and place the pillow 2 in the designated position. When pressed, the Velcro 1 23 and the Velcro 2 13 are glued together, which makes it easier for the pillow 2 to provide effective support for the user and improves the convenience of using the sleeping bag.
[0053] Example 3
[0054] The difference between this embodiment and Embodiment 1 is that the pillow 2 is circular.
[0055] Pillow 2 is hollow and has a neck support opening on one side. When using the sleeping bag, the user can place their neck in the neck support opening to support the neck, which conforms to the physiological curvature of the human body and helps to improve the user's sleep comfort.
[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
