DETAILED DESCRIPTION

[0027] Although the multifunctional sleeping bags currently on the market can be switched between the cloak form and the sleeping bag form, their hoods are fixed at the middle opening of the blanket. When the multifunctional sleeping bag is in the sleeping bag form, the hood will be located at the side of the sleeping bag and become a redundant part. It may also be piled up at the waist of the user and affect the comfort. In addition, the facial opening of the hood may cause the sleeping bag to be windy and affect warmth retention.

[0028] Therefore, the present invention improves the existing multifunctional sleeping bag by designing the hat to be a detachable structure: when in the cloak form, the hat is set in the middle of the blanket as a cloak; when in the sleeping bag form, it is connected to the edge of the blanket as a sleeping bag hat, further improving the warmth retention of the sleeping bag. In addition, the present invention further designs the hood opening connecting the middle part of the blanket and the hat to be closable, and other windproof and warm-keeping details, so as to maximize the warmth retention and comfort of the multifunctional sleeping bag.

[0029] The solutions of various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Please also see Figure 1 and Figure 2 The multifunctional sleeping bag provided in Example 1 of the present invention includes a blanket 10 and a hat 20. A hood opening 11 is provided in the middle of the blanket 10, and a partial edge of the blanket 10 is used as a hood edge 13, so that the hat 20 can be detachably connected to the hood opening 11 of the blanket 10, and can also be detachably connected to the hood edge of the blanket 10.

[0032] Specifically, in the present embodiment 1, the blanket 10 has a rectangular shape, including two long sides and two wide sides. In the design of the present embodiment, the area from one end of one of the wide sides to its midpoint is used as the hooded edge 13 of the blanket 10. That is, one end point of the hooded edge 13 is located at one end of the wide side, and the other end point of the hooded edge 13 is located at the midpoint of the wide side. The other wide side of the blanket 10 is referred to as the opposite side 16 of the hooded edge 13, and the two long sides are referred to as the adjacent sides 15 of the hooded edge 13. Please also refer to Figure 3 A blanket edge hood portion 14 covering the entire hood edge 13 is provided at the hood edge 13 of the blanket 10. Figure 4 A narrow linear slit is provided in the middle of the blanket 10 as a hood opening 11, and a hood opening hood portion 12 is provided along the edge of the hood opening 11 of the blanket 10. In the present embodiment 1, the hood opening 11 is located exactly on the line connecting the midpoints of the two wide sides of the blanket 10 after closing, and the line connecting the midpoints of the two wide sides is also the symmetry axis 102 of the rectangular blanket 10. In this way, when the blanket 10 is to be folded, the user can conveniently use the hood opening 11 as a folding position, grab the blanket 10 from the vicinity of the hood opening 11, and the blanket 10 can be folded more quickly and naturally along the symmetry axis 102, which is convenient for storage or transformation into a sleeping bag form.

[0033] The hat 20 is provided with a neck opening 201 and a face opening 202. The neck opening 201 is an opening surrounding the neck of the user when the hat 20 is worn on the user's head, and the face opening 202 is an opening for exposing the face of the user. A blanket connecting portion 21 is provided along the edge of the neck opening 201 of the hat 20, and the blanket connecting portion 21 can be respectively connected with the cap opening connecting portion 12 and the blanket edge connecting portion 14 of the blanket 10.

[0034] In one embodiment, the cap and hood portion 12 includes three male snap buttons arranged at intervals on the seam edge of one side of the slit of the cap and hood portion 11, as the first cap and hood portion 12a of the cap and hood portion 12; and three female snap buttons arranged at intervals on the seam edge of the other side of the slit, as the second cap and hood portion 12b of the cap and hood portion 12, and the male snap buttons on the seam edge of one side of the slit and the female snap buttons on the seam edge of the other side are correspondingly buckled to close the cap and hood portion 11. Corresponding to the structure of the cap and hood portion 12, the blanket portion 21 of the hat 20 includes three female snap buttons arranged at intervals on one side of the midpoint in the length direction thereof, as the first blanket portion 21a; and three male snap buttons arranged at intervals on the other side of the midpoint thereof, as the second blanket portion 21b. The length of the blanket portion 21 is the dimension of its expansion along the transverse profile of the neck opening 201 of the hat 20. Furthermore, the blanket edge and hood portion 14 includes three male snap buttons arranged at intervals on one side of the midpoint thereof, as the first blanket edge connector 14a; and three female snap buttons arranged at intervals on the other side of the midpoint thereof, as the second blanket edge connector 14b. The female snap button of the first blanket connecting member 21a of the hat 20 can be fastened with the male snap button of the first cap opening connector 12a of the blanket 10, or with the male snap button of the first blanket edge connector 14a of the blanket 10; the male snap button of the second blanket connecting member 21b of the hat 20 can be fastened with the female snap button of the second cap opening connector 12b of the blanket 10, or with the female snap button of the second blanket edge connector 14b of the blanket 10.

[0035] In some other embodiments, the female buckles of the first blanket connecting member 21a, the second cap connecting member 12b, and the second blanket edge connecting member 14b can be replaced by buttons, or the fleece surface of Velcro, or the N pole of a magnet, or a chain on one side of a zipper; correspondingly, the male buckles of the second blanket connecting member 21b, the first cap connecting member 12a, and the first blanket edge connecting member 14a can be replaced by buttonholes, or the hook surface of Velcro, or the S pole of a magnet, or a chain on the other side of a zipper.

[0036] Also, see Figure 5 , a windshield strip 22 is also provided at the edge of the neck opening 201 of the hat 20, and the windshield strip 22 can cover the inner side of the blanket-connecting part 21. When the user wears the hat 20 on the head, the side close to the user's neck is the inner side of the blanket-connecting part 21, and the side away from the user's neck is the outer side. In this way, when the hat 20 is worn on the user's head, the windshield strip 22 of the hat 20 is located between the blanket-connecting part 21 and the user's neck to reduce air leakage at the connection part and increase the comfort of the multifunctional sleeping bag. Furthermore, the dimension of the blanket-connecting part 21 and the windshield strip 22 extending downward from the neck opening 201 of the hat 20 is its width, and the width of the windshield strip 22 is set to be greater than the width of the blanket-connecting part 21.

[0037] In some embodiments, the edges of the hooded edge of the blanket are connected by a folding connector 17, so that the blanket 10 forms a sleeping bag shape; the folding connector 17 includes a connecting section 17a arranged on the edge of the blanket 10 on one side of the hooded edge 14, and a connecting section 17b arranged on the edge of the blanket 10 on the other side of the hooded edge 14. Preferably, the connecting section 17a and the connecting section 17b are symmetrically arranged along the symmetry axis 102, for example, the connecting section 17a and the connecting section 17b are symmetrically arranged on two adjacent edges 15 respectively; or, the connecting section 17a is arranged on the adjacent edge 15 and the half-side opposite edge 16 located on one side of the symmetry axis 102, and the connecting section 17b is arranged on the adjacent edge 15 and the half-side opposite edge 16 located on the other side of the symmetry axis 102, so that the blanket can be folded neatly and enclosed into a sleeping bag shape. Specifically, in this embodiment, zipper chains are respectively arranged at the edges of the two adjacent sides 15 of the hooded edge 13, and the zipper chains at the edges of the two adjacent sides 15 can be engaged with each other. The opposite side 16 of the hooded edge 13 is provided with three male snap buttons at intervals on one side of the symmetry axis 102, and three female snap buttons are provided on the other side of the symmetry axis 102. The three male snap buttons and the three female snap buttons on the opposite side 16 of the hooded edge 13 can be engaged with each other. In this embodiment, the zippers and snap buttons located at the adjacent side 15 and the opposite side 16 of the hooded edge 13 are both folding connectors 17 of the blanket 10. Among them, the zipper on the adjacent edge 15 of the hooded edge 13 on one side of the symmetry axis 102 of the blanket 10 and the snap buttons on the opposite side 16 of the hooded edge 13 together constitute the connecting section 17a of the folding connector 17; the zipper on the adjacent edge 15 of the hooded edge 13 and the snap buttons on the opposite side 16 of the hooded edge 13 on the other side of the symmetry axis 102 together constitute the connecting section 2 17b of the folding connector 17.

[0038] See also Figure 6 and Figure 7When the multifunctional sleeping bag is in the sleeping bag form, the first blanket connecting member 21a of the hat 20 is connected to the first blanket edge connecting member 14a of the blanket 10, and the second blanket connecting member 21b of the hat 20 is connected to the second blanket edge connecting member 14b of the blanket 10, so that the hat 20 is fixed at the hood edge 13. The first hat opening connecting member 12a and the second hat opening connecting member 12b of the blanket 10 are engaged with each other to close the hood opening 11. The connecting segment 17a and the connecting segment 2 17b of the folding connecting member 17 are combined with each other, so that the blanket 10 is folded and enclosed into a sleeping bag shape along the symmetry axis 102. At this time, the end point of the hood edge 13 located at the middle point of the wide side where it is located, and the middle point of the opposite side 16 of the hood edge 13 are both the folding points 101 formed by the blanket 10 at its edge. When the multifunctional sleeping bag is in the cloak form, the connecting segment 17a and the connecting segment 2 17b of the folding connecting member 17 are separated from each other. The first blanket connecting piece 21a of the hat 20 is connected to the first hat opening connecting piece 12a of the blanket 10, and the second blanket connecting piece 21b of the hat 20 is connected to the second hat opening connecting piece 12b of the blanket 10, so that the hat 20 is fixed at the hat opening 11 to form a cloak shape.

[0039] For further information, see Figure 8 , the multifunctional sleeping bag can be unfolded to wrap the hammock 30 from bottom to top, and used as a warm pad for the hammock 30. Specifically, a first channel 161 is provided at the edge of the opposite side 16 of the hooded edge 13 of the blanket 10, and a first elastic cord 162 is passed through the first channel 161. A second channel 131 is provided at the edge of the wide side where the hooded edge 13 of the blanket 10 is located, and a second elastic cord 132 is passed through the second channel 131. A third channel 231 is provided at the edge of the face opening 202 of the hat 20, and a third elastic cord 232 is passed through the third channel 231. Each elastic cord includes an elastic cord 18a and cord buckles 18b located at both ends of the elastic cord 18a. The folding connector 17 is opened, and the two ends of the first elastic cord 162 and the second elastic cord 132 are pulled to tighten the wide side where the hooded edge 13 is located and the opposite side 16 of the hooded edge 13. The ends of the pulled out elastic cords can be connected to the buckles 31 at the two ends of the hammock 30 through a knot. At this time, the blanket 10 wraps the hammock 30 from bottom to top to keep the hammock 30 warm. At the same time, the hat 20 can be removed from the blanket 10 and put on the user's head alone to keep warm. The two ends of the third elastic cord 232 are pulled to reduce the face opening 202 of the hat 20. The two ends of the third elastic cord 232 can be connected to each other through a knot and stuck at the user's chin, so that the hat 20 is more firmly worn on the user's head.

[0040] Example 2

[0041] See also Fig. 9, the shape of the blanket 10' of the multifunctional sleeping bag in this embodiment 2 is designed to be circular. Part of the edge of the circular blanket 10' serves as the hooded edge 13 of the blanket 10'. Specifically, according to the conventional ratio of the height and shoulder width of a human body, the hooded edge 13 of this embodiment is arranged along one twelfth of the circumference of the circular blanket 10'. At this time, the line connecting the middle point of the hooded edge 13 and the middle point of all the edges of the blanket 10 except the hooded edge 13 passes through the center of the circular blanket 10, and the line connecting the middle point of the hooded edge 13 and the middle point of all the edges of the blanket 10 except the hooded edge 13 is the symmetry axis 102' of the circular blanket 10. A narrow linear slit is provided in the middle of the blanket as the hooded opening 11, which can intersect with the symmetry axis 102' after closing, or is exactly located on the symmetry axis 102'. Preferably, the middle point of the hooded opening 11 after closing coincides with the center of the circular blanket 10'. In this way, when the blanket 10' needs to be folded, the user can use the hood opening 11 as a folding position, grab the blanket 10' from the vicinity of the hood opening 11, and fold the circular blanket 10' along its symmetry axis 102' conveniently and quickly. A blanket edge hood portion 14 covering the entire hood edge 13 is provided at the hood edge 13, and a hat opening hood portion 12 is provided at the edge of the hood opening 11. The structures of the hat 20, the blanket edge hood portion 14, and the hat opening hood portion 12 of this embodiment 2 are the same as those of the embodiment 1, and are not described in detail here.

[0042] A folding connector is provided on the edge of the blanket except the hooded edge 13, so that the circular blanket 10' can be folded and enclosed into a sleeping bag shape. Specifically, a side chain of a zipper is provided on the edge of all blankets 10 except the hooded edge 13 located on one side of the symmetry axis 102', as a connecting section 17a of the folding connector 17; and a side chain of a zipper is provided on the edge of all blankets 10 except the hooded edge 13 located on the other side of the symmetry axis 102, as a connecting section 2 17b of the folding connector 17. By joining the two side chains of the zipper, the circular blanket 10' can be folded and enclosed along the symmetry axis 102. At this time, the middle point of the hooded edge 13 and the middle points of all edges except the hooded edge 13 are both the folding points 101 formed at the edges of the blanket 10.

[0043] In addition, the edge of the blanket 10' in the second embodiment is symmetrically provided with a first channel 161 and a second channel 131, and the first elastic cord 162 and the second elastic cord 132 are respectively passed through the first channel 161 and the second channel 131, so that the multifunctional sleeping bag can wrap the hammock 30 and be used as a hammock warming pad. Specifically, the first channel 161 and the second channel 131 are arranged according to the length-width ratio of the hammock to cover one sixth of the circumference of the edge of the circular blanket 10', so that the blanket 10' can wrap the hammock from bottom to top. Preferably, the middle point of the first channel 161 in the length direction coincides with the middle point of all edges of the blanket 10' except the hooded edge 13, and the middle point of the second channel 131 in the length direction coincides with the middle point of the hooded edge 13. At this time, when the blanket 10' is used as a hammock warming pad, the direction of the rolling folds of the blanket 10' after pulling the first elastic cord 162 and the second elastic cord 132 is consistent with the direction after the hooded opening 11 is closed, which is conducive to the smooth rolling and folding of the blanket 10' and also conducive to the hooded opening 11 to maintain a closed state at this time, reduce air leakage, and ensure the warming effect.

[0044] The multifunctional sleeping bag of the present invention can be a cape, a sleeping bag, or a hammock warming pad, and has various functions, and is suitable for outdoor hiking and camping. Furthermore, compared with the prior art, the multifunctional sleeping bag of the present invention can be detachably connected to the hood edge of the blanket or to the hood opening by setting a hat, so that the hat can play its warming role in any form of the multifunctional sleeping bag, making the best use of it. In addition, by setting a first hat opening connector and a second hat opening connector, the hat opening hood portion of the hood opening can be used to connect the hat or to close the hood opening, thereby reducing air leakage of the sleeping bag, killing two birds with one stone. Furthermore, by setting a windshield strip on the hat, air leakage at the connection portion between the hat and the blanket can be reduced, thereby increasing the comfort of the hat.
