[0001] The utility model relates to the technical field of sleeping bags, in particular to a double-layer double-opening sleeping bag with multiple temperature scales. Background Art

[0002] Sleeping bags are the main warming equipment for outdoor camping. Since sleeping bags need to be carried out, warmth (temperature standard) and portability are two factors that must be considered when designing and producing sleeping bags.

[0003] Today's sleeping bags, whether envelope or mummy style, are composed of an upper piece and a lying layer. The thickness is fixed, and the warmth effect can only be adjusted by closing and opening the zipper.

[0004] Current two-piece sleeping bags offer limited thermal adjustment. Each fill weight corresponds to a specific temperature scale, so brands often produce multiple models of each sleeping bag to meet the demands of various seasons and temperatures. For example, a cotton sleeping bag often comes in sizes of 100g / ㎡, 200g / ㎡, 250g / ㎡, and 300g / ㎡, while a down sleeping bag often comes in sizes of 200g, 400g, 600g, and 1000g.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 This utility model provides a multi-temperature double-layer, double-opening sleeping bag comprising a reclining layer 1, a covering layer 2, and a topping layer 3. The reclining layer 1 provides a stable sleeping surface for the user. These layers are all made of comfortable and durable materials. The covering layer 2 is hingedly connected to the sidewalls of the reclining layer 1, forming a sleeping compartment between the covering layer 2 and the reclining layer 1. This compartment serves as the user's primary resting space, and the covering layer 2 provides a certain degree of warmth and protection.

[0026] The side walls of the sleeping layer 1 are hingedly connected to a cover layer 3, which covers the cover layer 2 and further enhances the sleeping bag's thermal insulation. A closure adjustment member 4 is provided between the cover layer 3 and the sleeping layer 1 to control the connection between the two, allowing for flexible adjustment of the connection between the cover layer 3 and the sleeping layer 1.

[0027] The connection states of the covering layer 3 and the lying layer 1 include a half-covered state, a fully covered state and a fully opened state;

[0028] In the half-covered state, the covering layer 3 partially covers the covering layer 2. At this time, the sleeping bag has a moderate warmth retention level and is suitable for environments with slightly higher temperatures.

[0029] When the ambient temperature drops, the covering layer 3 can be adjusted to a full-cover state, completely covering the covering layer 2, thereby greatly improving the thermal insulation performance of the sleeping bag and adapting to sleeping needs at lower temperatures.

[0030] When the temperature is high or ventilation is required, the covering layer 3 can be adjusted to a fully open state, and only the covering layer 2 is left, making the sleeping bag more breathable and cool.

[0031] This double-layer, double-opening design greatly expands the temperature range of the sleeping bag. By flexibly adjusting the position of the cover layer 3, the sleeping bag can be adapted to a variety of weather conditions.

[0032] For example, in spring and autumn, the temperature changes greatly, which may be warm during the day and cooler at night. When using the sleeping bag of the present invention, the cover layer 3 can be fully opened or half-covered during the day and fully covered at night to meet the temperature requirements of different time periods.

[0033] On summer nights, if the temperature drops suddenly, the cover layer 3 can be quickly adjusted to a half-cover or full-cover state to provide additional warmth.

[0034] Specifically, the cover layer 2 and the additional cover layer 3 are positioned on either side of the reclining layer 1, opening sideways to increase the thickness range of the upper layer. When the user lies on the reclining layer 1, the cover layer 2 and additional cover layer 3 on either side can be opened and closed more conveniently. For example, to adjust the warmth of the sleeping bag, the user can easily adjust the cover layer 2 and additional cover layer 3 from either side without having to move their body significantly, thus improving ease of use.

[0035] Furthermore, this design makes the sleeping bag more organized when unfolded and stored. When the sleeping bag is unfolded, the covering layer 2 and the cover layer 3 on both sides can be symmetrically distributed on both sides of the lying layer 1, which is not only aesthetically pleasing but also easier to fold and organize when stored, reducing the storage space required.

[0036] At the same time, such a design is also beneficial to the stability of the sleeping bag during use. When the user turns over or moves in the sleeping bag, the covering layer 2 and the cover layer 3 on both sides can better maintain the shape of the sleeping bag, prevent the sleeping bag from deformation or displacement, and provide a more comfortable and safe sleeping environment for the user.

[0037] In addition, the covering layer 2 and the additional covering layer 3 are respectively arranged on both sides of the lying layer 1. When the covering layer 2 is covered on the lying layer 1, the additional covering layer 3 can wrap the opening and closing ends of the covering layer 2 and the lying layer 1, thereby increasing the thermal insulation performance of the sleeping bag.

[0038] Specifically, the free end of the covering layer 2 is provided with a fastener 5 connected to the lying layer 1. The fastener 5 is a simple fixing buckle that can quickly and easily fix the covering layer 2 to the lying layer 1 to prevent the covering layer 2 from accidentally opening during use, thereby ensuring the warmth retention effect of the sleeping bag.

[0039] At the same time, the design of the fastener 5 also facilitates the user's operation, making the opening and closing of the cover layer 2 simpler and faster. When the cover layer 2 needs to be opened, only the fastener 5 needs to be easily operated, which does not cause too much trouble to the user.

[0040] Specifically, the fastening part 5 includes a sub-button 51 and a female button 52. Both the sub-button 51 and the female button 52 can be olive buttons, which are easy to use and have simple fastening operations. The sub-button 51 is fixed to the free end of the covering layer 2, and the female button 52 is fixed to the connection between the cover layer 3 and the lying layer 1. The sub-button 51 and the female button 52 are snap-fitted. When the covering layer 2 needs to be fixed on the lying layer 1, it is only necessary to snap the sub-button 51 and the female button 52 into each other to achieve quick fastening, ensuring that the sleeping bag will not affect the warmth effect due to the looseness of the covering layer 2 during use.

[0041] Furthermore, when the cover layer 2 needs to be opened, the male buckle 51 and the female buckle 52 can be separated from each other, which is very convenient. This design of the fastener 5 not only improves the convenience of use of the sleeping bag, but also enhances the overall stability and reliability of the sleeping bag, providing the user with a better sleeping experience.

[0042] Specifically, at least two groups of fasteners 5 are provided, so that the connection states of the covering layer 2 and the lying layer 1 can be in various forms, namely, a half-covered state, a fully covered state and a fully opened state.

[0043] When in the half-covered state, the user can adjust the coverage of the cover layer 2 by selecting the number of connection groups of the fasteners 5 according to actual needs to adapt to the current temperature.

[0044] The full cover state can cover the whole body and provide the user with maximum warmth and protection.

[0045] The fully open position makes it easy for users to quickly enter or exit the sleeping bag, or to clean or air the sleeping bag. At the same time, the fully open position also makes the sleeping bag more convenient to store and carry, and it can be folded flat to reduce space.

[0046] Specifically, the closure adjustment member 4 is a zipper, preferably a self-locking zipper. The two zipper elements are located on the sidewalls of the cover layer 3 and the reclining layer 1, respectively. The self-locking zipper provides a reliable locking function, ensuring the stability of the sleeping bag during use. The cover layer 3 can be positioned in three states: partially closed, fully closed, and fully open. The zipper is easy to operate and provides a good closure.

[0047] Specifically, the hinged end of the cover layer 2 is integrally formed with the reclining layer 1, and the hinged end of the cover layer 3 is also integrally formed with the reclining layer 1, making it less likely to separate or become damaged during use. This integral molding also reduces gaps at the connection points, improving the overall sealing of the sleeping bag and better preventing cold air and dust from entering the sleeping bag, providing a more comfortable sleeping environment for the user.
