Description

Technical Field

[0001] This application relates to the technical field of outdoor products, and particularly relates to a sleeping bag. Background Art

[0002] Outdoor activities, such as camping, hiking, and mountaineering, often require spending the night under various climate conditions. As an important outdoor equipment, a sleeping bag can provide a warm and comfortable sleeping environment for users at night. Existing sleeping bags are usually designed with thickness according to the expected temperature range of use, and can thus be divided into summer, winter, and three-season sleeping bags to meet the needs under different climate conditions.

[0003] However, there are some limitations in the design of existing sleeping bags. First, existing sleeping bags usually can only be applicable to a specific temperature range, which limits the versatility and adaptability of the sleeping bags. When users face temperature fluctuations or multi-day activities, they may need to carry multiple sleeping bags to adapt to different climate conditions, increasing the burden and cost of carrying. Second, the heat preservation performance of existing sleeping bags is fixed and cannot be adjusted according to the actual needs of users. In some cases, it may cause different users to feel overheated or too cold at night, affecting sleep. Summary of the Invention

[0004] An object of this application is to provide a sleeping bag with adjustable thickness, which can adjust the heat preservation performance according to the needs of users and environmental conditions.

[0005] To achieve the above object, the technical solution adopted in this application is: a sleeping bag, including a sleeping pad and a sleeping quilt. The sleeping quilt includes a first quilt body and a second quilt body. The first quilt body is detachably connected to the sleeping pad, the second quilt body is connected to the first quilt body, and the second quilt body can be unfolded away from the first quilt body or folded inside or outside the first quilt body, so that when the second quilt body is unfolded, the first quilt body and the second quilt body can selectively cover the sleeping pad, and when the second quilt body is folded, the first quilt body and the second quilt body are stacked and cover the sleeping pad.

[0006] As a preference, the bottom edge of the second quilt body is fixedly connected to the top edge of the first quilt body to form a fixed edge, and the remaining edges of the second quilt body are detachably connected to the first quilt body to form free edges. Further, the second quilt body can be turned over relative to the first quilt body with the fixed edge as the fixed end, and when the second quilt body is unfolded away from the first quilt body, the second quilt body is located above the first quilt body.

[0007] As another preference, the bottom edge of the second quilt body and the top edge of the first quilt body are connected by at least two suture fixing parts, and the suture fixing parts are arranged at intervals. An air vent for external air to flow in is formed between two adjacent suture fixing parts.

[0008] More preferably, a third connecting member is provided between each of the free edges and the first cover body, and the third connecting member can be opened or closed along each of the free edges. When the third connecting member is closed, the second cover body is folded and disposed inside or outside the first cover body. When the third connecting member is opened, the second cover body is unfolded relative to the first cover body and disposed above the first cover body.

[0009] Furthermore, a first connecting member is provided between the side edge of the first cover body and the sleeping pad, and the first connecting member can be opened or closed to separate or connect the side edge of the first cover body from the sleeping pad. A second connecting member is provided between the bottom edge of the first cover body and the sleeping pad, and the second connecting member can be opened or closed to separate or connect the bottom edge of the first cover body from the sleeping pad. The first connecting member and the second connecting member can be opened or closed independently of each other.

[0010] Furthermore, an additional cover body is provided between the top edge of the first cover body and the bottom edge of the second cover body. When the first cover body and the second cover body are stacked and disposed on the sleeping pad, the additional cover body can be folded over to cover the opening between the first cover body and the sleeping pad, so as to use the additional cover body as a windproof strip.

[0011] Furthermore, the first connecting member, the second connecting member, and the third connecting member can be independently implemented as one of a zipper, a magic tape, and a frog closure.

[0012] Furthermore, the sleeping bag further includes a sleeping cap, the sleeping cap is connected to the top of the sleeping pad, a connecting rope sleeve is provided in the middle of the sleeping cap, and a connecting buckle is provided in the middle of the top edge of the first cover body. The connecting buckle is adapted to be connected and cooperated with the connecting rope sleeve, so that the middle of the sleeping cap and the middle of the top edge of the first cover body can be detachably connected.

[0013] Furthermore, a pillow is connected inside the sleeping cap, and the pillow core inside the pillow is detachably connected to the sleeping cap.

[0014] Furthermore, the thickness of the first cover body is greater than the thickness of the second cover body.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows:

[0016] The thickness of the quilt of the sleeping bag of the present application is adjustable, and the user can adjust the thickness of the quilt according to the ambient temperature. When the temperature is low, the user can fold the second quilt body inside or outside the first quilt body, so that the first quilt body and the second quilt body are stacked and simultaneously cover the sleeping mat. When the user lies on the sleeping mat, he can be covered by both the first quilt body and the second quilt body at the same time. The thickness of the quilt is relatively thick and the heat preservation performance is good, which can meet the user's use under low temperature environmental conditions; when the temperature is high, the user can unfold the second quilt body away from the first quilt body outward, and the first quilt body and the second quilt body cover the sleeping mat alternatively. When the user lies on the sleeping mat, he can choose to cover himself with the first quilt body or the second quilt body by himself. At this time, the thickness of the quilt is relatively thin and the heat preservation performance is average, and the sleeping bag also has better comfort when used under higher ambient temperature conditions.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0027] The terms "comprising" and "having" in the description and claims of the present application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that comprises a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0028] Referring to Figures 1-6 the embodiments shown, the present application provides a sleeping bag, which includes a sleeping pad 100 and a sleeping quilt 200. The sleeping quilt 200 includes a first quilt body 210 and a second quilt body 220. The first quilt body 210 is detachably connected to the sleeping pad 100. The second quilt body 220 is connected to the first quilt body 210. The second quilt body 220 can be turned over and unfolded away from the first quilt body 210, or the second quilt body 220 can be turned over and folded inwards or outwards of the first quilt body 210. When the second quilt body 220 is unfolded relative to the first quilt body 210, the first quilt body 210 and the second quilt body 220 are laid flat. The user can choose to roll up and fold the first quilt body 210 or the second quilt body 220 according to the ambient temperature, so that only one of the first quilt body 210 and the second quilt body 220 covers the sleeping pad 100. When the second quilt body 220 is turned over and folded, the first quilt body 210 and the second quilt body 220 are stacked, and the first quilt body 210 and the second quilt body 220 cover the sleeping pad 100 at the same time.

[0029] The sleeping bag provided by this application has an adjustable thickness of the quilt 200. Users can adjust the thickness of the quilt 200 according to the ambient temperature, so that the quilt 200 can be used under different climatic conditions and temperatures, and the sleeping bag has good applicability. When the ambient temperature is relatively low, the user can fold the second quilt body 220 inside or outside the first quilt body 210. At this time, the first quilt body 210 and the second quilt body 220 are stacked. Preferably, the first quilt body 210 covers the outside of the second quilt body 220. The first quilt body 210 and the second quilt body 220 cover the sleeping pad 100 at the same time. When the user lies on the sleeping pad 100, they can be covered by the first quilt body 210 and the second quilt body 220 at the same time. The quilt 200 is composed of the first quilt body 210 and the second quilt body 220. The thickness of the quilt 200 is relatively thick and has good heat preservation performance, which can meet the needs of users in low-temperature environments. When the ambient temperature is relatively high, the user can turn and unfold the second quilt body 220 away from the first quilt body 210. At this time, the first quilt body 210 and the second quilt body 220 are laid flat. The user can choose to roll up and fold the first quilt body 210 or the second quilt body 220. Preferably, the user can roll up and fold the first quilt body 210 at the bottom of the sleeping pad 100 so that the second quilt body 220 covers the sleeping pad 100. When the user lies on the sleeping pad 100, they are only covered by the second quilt body 220. The quilt 200 is only composed of the second quilt body 220. The thickness of the quilt 200 is relatively thin, so that users can also use this sleeping bag in spring, summer and other seasons with higher temperatures.

[0030] In Figure 1 In the illustrated embodiment, a first connecting member 300 is provided between the side edge of the first quilt body 210 and the sleeping pad 100. The first connecting member 300 can be opened or closed to separate or connect the side edge of the first quilt body 210 from the sleeping pad 100. A second connecting member 400 is provided between the bottom edge of the first quilt body 210 and the sleeping pad 100. The second connecting member 400 can be opened or closed to separate or connect the bottom edge of the first quilt body 210 from the sleeping pad 100. The bottom edge of the second quilt body 220 is fixedly connected to the top edge of the first quilt body 210 to form a fixed edge 221. The top edge and side edges of the second quilt body 220 are separably connected to the first quilt body 210 to form free edges 222. A third connecting member 500 is provided between each free edge 222 and the first quilt body 210. The third connecting member 500 can be opened or closed to separate or connect the free edge 222 of the second quilt body 220 from the first quilt body 210. The first connecting member 300, the second connecting member 400 and the third connecting member 500 are each independently opened or closed. The user can operate the first connecting member 300, the second connecting member 400 and the third connecting member 500 to open or close and flip and fold the first quilt body 210 or the second quilt body 220 to adjust the thickness of the quilt 200 according to the actual ambient temperature during use.

[0031] Specifically, as Figure 4As shown in the figure, when the user uses the sleeping bag in winter with a relatively low ambient temperature, the user can close the first connecting member 300, the second connecting member 400, and the third connecting member 500. At this time, the side and bottom edges of the first quilt body 210 are connected to the sleeping mat 100, the free edge 222 of the second quilt body 220 is connected to the first quilt body 210, and the first quilt body 210 and the second quilt body 220 are stacked to form a sleeping quilt 200 covering the sleeping mat 100 to form a heat-insulating space with better airtightness, which can meet the user's usage requirements in the case of a relatively low ambient temperature;

[0032] When the user uses the sleeping bag in autumn with a cool ambient temperature, the user can close the first connecting member 300 and the third connecting member 500 and open the second connecting member 400. At this time, the side edge of the first quilt body 210 is connected to the sleeping mat 100, the bottom edge of the first quilt body 210 is separated from the sleeping mat 100 to form an opening, the free edge 222 of the second quilt body 220 is connected to the first quilt body 210, and the first quilt body 210 and the second quilt body 220 are stacked to form a sleeping quilt 200 covering the sleeping mat 100. The opening is suitable for communicating with the external environment and the heat-insulating space. Then, when the user feels too hot, the feet can be stretched out of the heat-insulating space, and the external cold air can flow into the heat-insulating space through the opening;

[0033] As Figures 5-6 shown in the figure, when the user uses the sleeping bag in spring with a warm ambient temperature, the user can close the second connecting member 400 and open the first connecting member 300 and the third connecting member 500. At this time, the side edge of the first quilt body 210 is separated from the sleeping mat 100, the bottom edge of the first quilt body 210 is connected to the sleeping mat 100, the free edge 222 of the second quilt body 220 is separated from the first quilt body 210, and the second quilt body 220 can be unfolded and laid flat above the first quilt body 210 with the fixed edge 221 as the fixed end relative to the first quilt body 210. The first quilt body 210 can be rolled up and folded downward with the bottom edge as the fixed end at the bottom of the sleeping mat 100 so that only the second quilt body 220 forms a sleeping quilt 200 covering the sleeping mat 100. The thickness of the sleeping quilt 200 becomes thinner, and the heat preservation performance of the sleeping quilt 200 is reduced, which is suitable for use in spring with a warm temperature;

[0034] As Figure 1 shown in the figure, when the user uses the sleeping bag in summer with a relatively high ambient temperature, the user can open the first connecting member 300 and the second connecting member 400 and close the third connecting member 500. At this time, the side and bottom edges of the first quilt body 210 are separated from the sleeping mat 100, the free edge 222 of the second quilt body 220 is connected to the first quilt body 210, and the user can remove the first quilt body 210 together with the second quilt body 220 from the sleeping mat 100, leaving only the sleeping mat 100, so that the sleeping bag is suitable for use in summer with a relatively high temperature.

[0035] It should be noted that the top edges of the first covering body 210 and the second covering body 220 are the edges located above when the second covering body 220 is unfolded by folding and the first covering body 210 and the second covering body 220 are laid flat, and the bottom edges of the first covering body 210 and the second covering body 220 are the edges located below when the second covering body 220 is unfolded by folding and the first covering body 210 and the second covering body 220 are laid flat.

[0036] Furthermore, the bottom edge of the second covering body 220 and the top edge of the first covering body 210 are connected by at least two stitch fixing parts 240, and ventilation openings 250 for external air to flow in are formed between the stitch fixing parts 240. Preferably, as Figure 3 shown, the bottom edge of the second covering body 220 and the top edge of the first covering body 210 are connected by three stitch fixing parts 240, and the three stitch fixing parts 240 are arranged at intervals, so that two ventilation openings 250 are formed between the three stitch fixing parts 240, and external air can flow into the heat preservation space between the sleeping bag 200 and the sleeping mat 100 through the ventilation openings 250. Specifically, when the first covering body 210 is rolled up and folded and the second covering body 220 covers the sleeping mat 100, external air can flow into the heat preservation space between the second covering body 220 and the sleeping mat 100 through the ventilation openings 250, ensuring the comfort of the sleeping bag at a relatively high temperature; during the use of the sleeping bag by the user, the feet can also pass through the ventilation openings 250 and extend outside the heat preservation space.

[0037] It is worth mentioning that in some preferred embodiments, connecting pieces such as zippers and Velcro can also be provided at the ventilation openings 250 to open and close the ventilation openings 250, so that the user can control the opening and closing of the ventilation openings 250 according to actual usage needs.

[0038] The implementation forms of the first connecting piece 300, the second connecting piece 400 and the third connecting piece 500 are not limited, and the first connecting piece 300, the second connecting piece 400 and the third connecting piece 500 can be independently implemented as common separable connection methods such as Velcro, zippers and buttons. Preferably, in Figures 1-3In the illustrated embodiment, the first connecting member 300 is implemented as a first zipper disposed between the side of the first body 210 and the mattress 100, and the second connecting member 400 is implemented as a second zipper between the bottom edge of the first body 210 and the mattress 100. As a very practical and common closing connecting member, the zipper has the advantages of being quickly opened and closed, durable, and having good sealing performance. Selecting zippers for the first connecting member 300 and the second connecting member 400 can take into account durability while ensuring sealing performance, and the first connecting member 300 and the second connecting member 400 can be quickly opened and closed. The third connecting member 500 is implemented as a snap button disposed between the free edge 222 of the second body 220 and the first body 210. The snap button specifically includes a male button and a female button, which are respectively disposed on the first body 210 and the second body 220. When the first body 210 and the second body 220 need to be connected, the female button and the male button can be pressed. When the first body 210 and the second body 220 need to be separated, the female button and the male button can be pulled. The snap button is convenient for disassembly and connection and also has good concealment.

[0039] In addition, in most cases, the thickness of the second body 220 is less than that of the first body 210, that is, the first body 210 can be implemented as a thermal insulation cotton quilt, and the second body 220 can be implemented as a cool air-conditioning quilt. Of course, the thickness of the second body 220 can also be greater than that of the first body 210, that is, the second body 220 is implemented as a thermal insulation cotton quilt, and the first body 210 is implemented as a cool air-conditioning quilt; or the thicknesses of the first body 210 and the second body 220 are equal.

[0040] In some preferred embodiments, an additional body 230 is further disposed between the top edge of the first body 210 and the bottom edge of the second body 220. One side of the additional body 230 is fixedly connected to the first body 210 and the second body 220, and thus the additional body 230 can be folded relative to the first body 210 and the second body 220. Specifically, when the second body 220 is folded inside or outside the first body 210 and stacked with the first body 210, the additional body 230 can be folded to cover the opening between the first body 210, the second body 220 and the mattress 100, so that the additional body 230 is used as a windproof strip. In addition, since the bottom edge and the side edge of the first body 210 are both connected to the mattress 100, and the bottom edge of the second body 220 is fixedly connected to the top edge of the first body 210, the positions of the first body 210 and the second body 220 relative to the mattress 100 are fixed and cannot be adjusted. Different users have different quilt covering habits. For example, some users are used to covering the quilt over the chest, and some users are used to covering the quilt over the neck. The fixed-position first body 210 and second body 220 cannot meet the quilt covering needs of different users. Therefore, setting the additional body 230 between the top edge of the first body 210 and the bottom edge of the second body 220 can meet the quilt covering needs of different users, and users can freely fold the additional body 230 to different positions.

[0041] As Figures 1-2 shown, the sleeping bag provided by the present application further includes a sleeping cap 110. The sleeping cap 110 is connected to the top of the sleeping pad 100. A pillow 120 is connected inside the sleeping cap 110. The pillow core inside the pillow 120 is detachably connected. A connecting rope sleeve 130 is arranged in the middle of the sleeping cap 110. A connecting buckle 211 is arranged in the middle of the top edge of the first quilt body 210. The connecting buckle 211 is adapted to cooperate with the connecting rope sleeve 130 so that the middle of the sleeping cap 110 and the middle of the top edge of the first quilt body 210 can be detachably connected. When two people lie in the sleeping bag, the connecting buckle 211 and the connecting rope sleeve 130 are cooperatively connected to connect the middle of the sleeping cap 110 and the middle of the top edge of the first quilt body 210 together, thereby preventing external air from flowing into the heat preservation space between the two people and further improving the heat preservation effect of the sleeping bag.
