Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a sleeping bag. Background Art

[0002] Textiles are essential daily necessities for people and come in many varieties, including clothing, bedding textiles (sheets, quilt covers, pillowcases, etc.), decorative textiles (curtains, carpets, etc.) and outdoor textiles.

[0003] As a commonly used outdoor tool, sleeping bags are generally composed of a bag body and a filler filled in the bag body. The bag body is generally made of waterproof, wear-resistant and breathable materials, and the filler is mostly made of thermal insulation materials such as down, synthetic fiber and cotton. When storing the sleeping bag, it is generally manually folded in half and stacked in layers and then placed in a storage bag. Manual folding and unfolding of the sleeping bag is relatively troublesome. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a sleeping bag that solves the problem that existing sleeping bags are relatively troublesome to store and unfold.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a sleeping bag, including a bag body, a winding drum is provided on one side of the bag body, a cavity is provided in the winding drum, a winding rod is rotatably connected in the cavity, an opening is provided on the side of the winding drum, one side of the bag body is connected to the winding rod through the opening, and the bag body is rolled up or pulled out of the cavity by rotating the winding rod.

[0006] Furthermore, a handle is provided at the end of the winding drum for driving the winding rod to rotate.

[0007] By adopting the above technical solution, the setting of the turning handle can conveniently drive the winding rod to rotate, thereby facilitating the winding of the bag body.

[0008] Furthermore, the reeling rod is provided with a protective belt along its length direction, and the protective belt corresponds to the position of the stitching provided on the bag body along its length direction.

[0009] By adopting the above technical solution, the setting of the protective belt can cover the gaps in the bag body, avoiding the poor thermal insulation effect at the filler isolation seams due to lack of filler, and effectively optimizing the thermal insulation effect of the sleeping bag.

[0010] Furthermore, the protective belts are arranged at intervals on the winding rod, and a through hole is opened on the side of the winding drum to accommodate the protective belts to pass freely.

[0011] By adopting the above technical solution, the provision of the through hole facilitates limiting the position of the protective belt after it extends from the cavity, so that the extended protective belt corresponds to the position of the suture of the bag body.

[0012] Furthermore, the protective belt and the bag body are detachably connected.

[0013] Furthermore, the side surfaces of the bag body and the protective belt are connected by Velcro.

[0014] By adopting the above technical solution and the Velcro sticking method, it is easy to disassemble.

[0015] Furthermore, a limiting plate is provided on the side of the bag body away from the winding drum, and the vertical distance of the limiting plate is greater than the vertical spacing of the openings.

[0016] By adopting the above technical solution, the limiting plate can facilitate personnel to operate the limiting plate to pull the bag out of the cavity and unfold it after the bag is stored in the storage tube.

[0017] Furthermore, a zipper opening is provided on the side of the bag body.

[0018] By adopting the above technical solution, the zipper opening makes it convenient for people to enter the sleeping bag.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The utility model provides a storage cylinder on the side of the bag body, and uses a reeling rod that is rotatably arranged in the cavity of the storage cylinder. The reeling rod is connected to one side of the bag body. When the sleeping bag is folded, the reeling action of the reeling rod is utilized to reel the sleeping bag into the cavity, thereby realizing rapid reeling of the sleeping bag. This design also facilitates the unfolding of the sleeping bag, effectively improving the convenience of using the sleeping bag.

[0021] 2. The utility model adopts a rolling method through a rolling rod. Compared with the traditional manual stacking bag folding method, the rolled bag has fewer wrinkles, and also avoids the problem of obvious wrinkles in the sleeping bag after long-term stacking and compression.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1 , a sleeping bag includes a bag body 100, which is generally in the shape of a rectangular parallelepiped structure. The bag body consists of two layers, an upper layer and an lower layer, with a cavity for sleeping formed between the two layers. The bag body 100 is filled with filler, generally down, and then the filler is limited to a fixed area of the bag body 100 by stitching 110 to prevent uneven distribution of the filler. A winding drum 200 is provided on one side of the bag body 100, and a cavity is provided in the winding drum 200. A winding rod 210 is rotatably connected in the cavity, and an opening 201 is provided on the side of the winding drum 200. One side of the bag body 100 is connected to the winding rod 210 through the opening 201. In this way, by rotating the winding rod 210, the bag body 100 can be pulled out of the cavity or stored in the cavity, so as to achieve the effect of quick folding and quick unfolding of the bag body 100, which greatly improves the convenience of operating the sleeping bag for the user.

[0031] In this embodiment, refer to Figure 1 and 2 The winding drum 200 preferably adopts a cylindrical structure, and the two ends of the winding rod 210 are rotatably installed on the two ends of the winding drum 200 through the rotating shaft 220, wherein a turning handle 230 is provided on the rotating shaft 220 at one end of the winding rod 210, and the turning handle 230 protrudes from the end of the winding drum 200. By rotating the turning handle 230, the winding rod 210 can be conveniently driven to rotate, so as to facilitate the rotation and winding of the bag body 100.

[0032] In this embodiment, refer to Figure 1 In order to prevent the bag body 100 from being excessively rolled into the cavity when the rolling rod 210 rotates, and to facilitate the bag body 100 to be pulled out of the cavity, a limiting plate 140 is provided on the side of the bag body 100 away from the rolling drum 200, and the vertical distance of the limiting plate 140 is greater than the vertical spacing of the opening 201. In this way, the setting of the limiting plate 140 can prevent the bag body 100 from being excessively contracted. At the same time, when the bag body 100 is extended from the rolling drum 200, it is also convenient for the staff to pull the limiting plate 140, and then quickly pull the rolled bag body 100 out of the cavity.

[0033] Based on the above embodiments, in order to reduce the problem that the thermal insulation effect of traditional sleeping bags is relatively reduced due to less filling at the seam 110, in this embodiment, a protective belt 300 is further provided on the winding rod 210. The protective belt 300 is arranged on the axial direction of the winding rod 210 corresponding to the position of the seam 110 of the bag body 100. When the bag body 100 is unfolded for use, the protective belt 300 can be covered on the seam 110 of the bag body 100, thereby reducing the airflow at the seam 110 of the bag body 100 and improving the thermal insulation effect of the bag body 100.

[0034] Furthermore, the protective belt 300 and the bag body 100 are detachably connected, and specific detachable methods include zippers, buckles, buttons, press buckles, or Velcro 130, etc. This embodiment is described in terms of the Velcro 130 being used for both.

[0035] In this embodiment, the Velcro 130 can be provided on the side of the sleeping bag, and the Velcro 130 is also provided on the end surface of the protective belt 300. In this way, the two Velcros 130 are adhered to each other, and the protective belt 300 can be stably covered on the seam 110 of the bag body 100. Of course, the Velcro 130 provided on the bag body 100 can also be provided along the seam 110, and the corresponding protective belt 300 is provided with corresponding Velcro 130 along its length direction to achieve the above effect. The setting position of the Velcro 130 may also be other positions, which will not be described one by one here.

[0036] Based on the above embodiment, since the suture 110 is arranged at intervals on the bag body 100, the corresponding protective belt 300 can be arranged at multiple intervals on the winding rod 210. In order to further limit the position of the protective belt 300 after extending out of the cavity so that it accurately corresponds to the position of the suture 110, a through hole can be opened at the position of the protective belt 300 corresponding to the winding drum 200. In this way, the position of the protective belt 300 is limited and guided by the through hole, which can improve the orderliness of the protective belt 300 when pulling out and winding it up and the accuracy of its correspondence with the position of the suture 110, and can also avoid the protective belt 300 from being relatively messy and accidentally entangled.

[0037] Reference Figure 1 and 3 In this embodiment, a zipper opening 120 can be opened on the side or end of the bag body 100 to facilitate people to enter the bag body 100 through the zipper opening 120.

[0038] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
