Embodiments for Carrying Out the Invention

[0009] Hereinafter, a plurality of embodiments including Embodiment 1, Embodiment 2 and their design variations of the present invention will be described. It should be noted that each component of the embodiments and design change examples described below can be combined with each other as long as they do not conflict with each other. Also, it should be noted that the materials, shapes, dimensions, numbers, arrangements, etc. of each component constituting each aspect of the embodiments and design variations described below are examples, and can be arbitrarily designed and changed as long as the same functions can be realized.

Examples

[0010] Hereinafter, the sleeping bag S1 according to a plurality of embodiments including Embodiment 1 of the present invention and its design modification examples will be described with reference to FIGS. 1A to 7B. FIGS. 1A to 7B show the sleeping bag S1 of Embodiment 1. FIGS. 1A to 2B show the Y - Y' direction, the X - X' direction, and the Z - Z' direction. The Y - Y' direction is the longitudinal direction of the sleeping bag body 100 of the sleeping bag S1, and includes the Y direction (one side of the longitudinal direction) and the Y' direction (the other side of the longitudinal direction). The X - X' direction is the lateral direction of the sleeping bag body 100 of the sleeping bag S1 that is substantially orthogonal to the Y - Y' direction, and includes the X direction (one side of the lateral direction) and the X' direction (the other side of the lateral direction). The Z - Z' direction is the thickness direction of the sleeping bag body 100 of the sleeping bag S1 that is substantially orthogonal to the Y - Y' direction and the X - X' direction, and includes the Z direction (the other side of the thickness direction) and the Z' direction (one side of the thickness direction).

[0011] The sleeping bag S1 includes a bag - shaped (so - called, envelope - type) sleeping bag body 100. The sleeping bag body 100 has a lower side portion 110 and an upper side portion 120. The lower side portion 110 is the portion on the Z' - direction side of the sleeping bag body 100, and is substantially rectangular when viewed from the Z - direction side. The upper side portion 120 is the portion on the Z - direction side of the sleeping bag body 100, and is substantially rectangular when viewed from the Z - direction side. The lower side portion 110 has a first side 111 in the Y direction, a second side 112 in the Y' direction, a third side 113 in the X direction, and a fourth side 114 in the X' direction. The upper side portion 120 has a first side 121 in the Y direction, a second side 122 in the Y' direction, a third side 123 in the X direction, and a fourth side 124 in the X' direction. Note that the second side 112 of the lower side portion 110 and the second side 122 of the upper side portion 120 can be formed in an arc shape convex in the Y' direction (not shown).

[0012] The fourth side 114 of the lower side portion 110 and the fourth side 124 of the upper side portion 120 may be connected to each other, and the lower side portion 110 and the upper side portion 120 may be composed of a single futon (see FIGS. 3A and 3B) filled with batting inside on the futon side, or may be configured to form a single piece of fabric (not shown). In this case, the lower side portion 110 and the upper side portion 120 can be overlapped with each other in the Z - Z' direction for use (see FIGS. 1A to 2B), or can be unfolded and used as a single futon (see FIGS. 3A and 3B) or a single piece of fabric.

[0013] Alternatively, the lower part 110 and the upper part 120 may each be constituted by a separate futon (not shown) filled with batting inside on the futon side, or may be constituted as a separate piece of fabric (not shown) (not shown). The fourth side 114 of the lower part 110 and the fourth side 124 of the upper part 120 may be detachably connected, or may be non-detachably connected by sewing or joining. In the former case, the lower part 110 and the upper part 120 can be used by overlapping each other in the Z-Z' direction, or can be used separately. In the latter case, the lower part 110 and the upper part 120 can be used by overlapping each other in the Z-Z' direction, or can be used by unfolding.

[0014] When the lower part 110 and the upper part 120 are configured to form a single futon (see FIGS. 3A and 3B) or a single piece of fabric (not shown), or when the lower part 110 and the upper part 120 are separate and the fourth side 114 of the lower part 110 and the fourth side 124 of the upper part 120 are non-detachably connected, the second side 112 and the third side 113 of the lower part 110 and the second side 122 and the third side 123 of the upper part 120 are openably and closably connected by a wire fastener 130. The wire fastener 130 has a substantially L-shaped first engaging tooth row provided on the second side 112 and the third side 113 of the lower part 110, a substantially L-shaped second engaging tooth row provided on the second side 122 and the third side 123 of the upper part 120, and a slider for opening and closing the first engaging tooth row and the second engaging tooth row. When the lower part 110 and the upper part 120 are overlapped and the first engaging tooth row and the second engaging tooth row are substantially parallel, the slider moves to close and release the first and second engaging tooth rows. In this way, the second side 112 and the third side 113 of the lower part 110 and the second side 122 and the third side 123 of the upper part 120 can be closed and released by the wire fastener 130. When the second side 112 and the third side 113 of the lower part 110 and the second side 122 and the third side 123 of the upper part 120 are closed by the wire fastener 130, the sleeping bag body 100 forms a bag shape.

[0015] When the lower part 110 and the upper part 120 are separate and the fourth side 114 of the lower part 110 and the fourth side 124 of the upper part 120 are detachably connected (not shown), the second side 112, the third side 113, and the fourth side 114 of the lower part 110 and the second side 122, the third side 123, and the fourth side 124 of the upper part 120 are connected by a wire fastener 130 so as to be openable and closable. The wire fastener 130 has a substantially L-shaped first engaging tooth row provided on the second side 112, the third side 113, and the fourth side 114 of the lower part 110, a substantially L-shaped second engaging tooth row provided on the second side 122, the third side 123, and the fourth side 124 of the upper part 120, and a slider for opening and closing the first engaging tooth row and the second engaging tooth row. When the lower part 110 and the upper part 120 are overlapped and the first engaging tooth row and the second engaging tooth row are substantially parallel, the slider moves to close and release the first and second engaging tooth rows. In this way, the second side 112, the third side 113, and the fourth side 114 of the lower part 110 and the second side 122, the third side 123, and the fourth side 124 of the upper part 120 are closed and released by the wire fastener 130. When the second side 112, the third side 113, and the fourth side 114 of the lower part 110 and the second side 122, the third side 123, and the fourth side 124 of the upper part 120 are closed by the wire fastener 130, the sleeping bag body 100 forms a bag shape.

[0016] In the state of forming a bag shape as described above, the sleeping bag body 100 has an opening O that opens in the Y direction. The opening O is provided between the first side 111 of the lower part 110 of the sleeping bag body 100 and the first side 121 of the upper part 120. Therefore, the first side 111 of the lower part 110 and the first side 121 of the upper part 120 are also the edge portions of the opening O. More specifically, the first side 111 of the lower part 110 is the lower edge portion on the Z' direction side of the opening O, and the first side 121 of the upper part 120 is the upper edge portion on the Z direction side of the opening O.

[0017] Note that the wire fastener 130 can be omitted. Also, instead of the wire fastener 130, a hook-and-loop fastener or a snap button may be used.

[0018] The sleeping bag S1 further includes at least one extension part. The at least one extension part is a cushion (see FIGS. 1A to 7B), a fabric (not shown), or a sheet (not shown) that is connected to the edge on the Z'-direction side of the opening O of the sleeping bag main body 100, that is, the first side 111 of the lower side part 110, and extends in the Y direction. The at least one extension part may be integrally connected to the first side 111 of the lower side part 110 of the sleeping bag main body 100, or may be a separate body from the sleeping bag main body 100 and be detachably connected (connected). The cushion, for example, has a structure in which the bag body is filled with batting. The sheet is, for example, a flexible sheet made of polyester taffeta, polyester oxford, nylon, cotton, or the like.

[0019] The at least one extension part can be substantially rectangular (see FIGS. 1A to 7B), substantially square (not shown), substantially semicircular (not shown), or substantially semi-elliptical (not shown) when viewed from the Z-direction side.

[0020] At least one extension part may include a first extension part 200a and a second extension part 200b (see FIGS. 1A to 7B). The first extension part 200a and the second extension part 200b have the same configuration as the at least one extension part described above. The first extension part 200a has a first end 201a on the Y direction side, a second end 202a on the Y' direction side, a third end 203a on the X' direction side, and a fourth end 204a on the X direction side. The second extension part 200b has a first end 201b on the Y direction side, a second end 202b on the Y' direction side, a third end 203b on the X' direction side, and a fourth end 204b on the X direction side. The second end 202a of the first extension part 200a is integrally or detachably connected to the edge on the Z' direction side of the opening O of the sleeping bag body 100, that is, the first side 111 of the lower part 110, and the second end 202b of the second extension part 200b is integrally or detachably connected to the edge on the Z' direction side of the opening O of the sleeping bag body 100, that is, the first side 111 of the lower part 110. The first extension part 200a and the second extension part 200b are arranged at intervals in the X-X' direction. More specifically, the first extension part 200a is arranged at an interval in the X direction with respect to the second extension part 200b, and the second extension part 200b is arranged at an interval in the X' direction with respect to the first extension part 200a.

[0021] The first extension part 200a and the second extension part 200b can be configured to have first parts 210a and 210b. The first part 210a of the first extension part 200a is the part on the Y-direction side and the X'-direction side of the first extension part 200a, and the first part 210b of the second extension part 200b is the part on the Y-direction side and the X-direction side of the second extension part 200b. For example, when the first extension part 200a and the second extension part 200b are substantially rectangular (see FIGS. 1A to 7B) or substantially square (not shown) when viewed from the Z-direction side, the first part 210a of the first extension part 200a is the corner part on the Y-direction side and the X'-direction side of the first extension part 200a (the end part in the X'-direction of the first end 201a), and the first part 210b of the second extension part 200b is the corner part on the Y-direction side and the X-direction side of the second extension part 200b (the end part in the X-direction of the first end 201b). When the first extension part 200a and the second extension part 200b are substantially semi-circular (not shown) or substantially semi-elliptical (not shown) when viewed from the Z-direction side, the first part 210a of the first extension part 200a is the end part on the Y-direction side and the X'-direction side of the first extension part 200a (the end part in the X'-direction of the first end 201a), and the first part 210b of the second extension part 200b is the end part on the Y-direction side and the X-direction side of the second extension part 200b (the end part in the X-direction of the first end 201b).

[0022] The first extension part 200a and the second extension part 200b can be configured to further include a second part 220a and a second part 220b. The second part 220a of the first extension part 200a is the part on the Y-direction side and the X-direction side of the first extension part 200a, and the second part 220b of the second extension part 200b is the part on the Y-direction side and the X'-direction side of the second extension part 200b. For example, when the first extension part 200a and the second extension part 200b are substantially rectangular (see FIGS. 1A to 7B) or substantially square (not shown) when viewed from the Z-direction side, the second part 220b of the first extension part 200a is the corner on the Y-direction side and the X-direction side of the first extension part 200a (the X-direction end of the first end 201a), and the second part 220b of the second extension part 200b is the corner on the Y-direction side and the X'-direction side of the second extension part 200b (the X'-direction end of the first end 201b). When the first extension part 200a and the second extension part 200b are substantially semi-circular (not shown) or substantially semi-elliptical (not shown) when viewed from the Z-direction side, the second part 220a of the first extension part 200a is the end on the Y-direction side and the X-direction side of the first extension part 200a (the X-direction end of the first end 201a), and the second part 220b of the second extension part 200b is the end on the Y-direction side and the X'-direction side of the second extension part 200b (the X'-direction end of the first end 201b).

[0023] The first extension part 200a can be configured to further include a first engaging part 211a. The second extension part 200b can be configured to further include a first engaging part 211b. The first engaging part 211a is provided on the first part 210a of the first extension part 200a. The first engaging part 211b is provided on the first part 210b of the second extension part 200b.

[0024] For example, the first engaging part 211a can be one of a set of snap buttons provided on the Z-direction side surface of the first part 210a (see FIGS. 1A to 6B) or one of the hook-and-loop fasteners (not shown), and the first engaging part 211b can be the other of the set of snap buttons provided on the Z'-direction side surface of the first part 210b (see FIGS. 1A to 6B) or the other of the hook-and-loop fasteners (not shown).

[0025] Alternatively, the first engaging portion 211a may be a substantially U-shaped hook or a substantially T-shaped toggle provided on the first portion 210a (not shown), and the first engaging portion 211b may be a loop or a ring provided on the first portion 210b (not shown). Alternatively, the first engaging portion 211a may be a loop or a ring provided on the first portion 210a (not shown), and the first engaging portion 211b may be a substantially U-shaped hook or a substantially T-shaped toggle provided on the first portion 210b (not shown).

[0026] Instead of the substantially U-shaped hook or the substantially T-shaped toggle, it is also possible to use a string. The string can be hooked (engaged) to a loop or a ring. Also, both the first engaging portion 211a and the first engaging portion 211b may be strings (not shown).

[0027] The first extension portion 200a can be configured to further include a second engaging portion 221a. The second extension portion 200b can be configured to further include a second engaging portion 221b. The second engaging portion 221a is provided on the second portion 220a of the first extension portion 200a. The second engaging portion 221b is provided on the second portion 220b of the second extension portion 200b.

[0028] For example, the second engaging portion 221a may be one of a set of snap buttons provided on the Z-direction side surface of the second portion 220a (see FIGS. 1A to 6B) or one of a surface fastener (not shown), and the second engaging portion 221b may be the other of the set of snap buttons provided on the Z'-direction side surface of the second portion 220b (see FIGS. 1A to 6B) or the other of the surface fastener (not shown).

[0029] Alternatively, the second engaging portion 221a may be a substantially U-shaped hook or a substantially T-shaped toggle provided on the second portion 220a (not shown), and the second engaging portion 221b may be a loop or a ring provided on the second portion 220b (not shown). Alternatively, the second engaging portion 221a may be a loop or a ring provided on the second portion 220a (not shown), and the second engaging portion 221b may be a substantially U-shaped hook or a substantially T-shaped toggle provided on the second portion 220b (not shown).

[0030] Instead of the substantially U-shaped hook or the substantially T-shaped toggle, it is also possible to use a string. Further, both the second engaging portion 221a and the second engaging portion 221b may be strings (not shown).

[0031] The first extension portion 200a can be folded back in the Y' direction so as to overlap the sleeping bag body 100 with the boundary between the first extension portion 200a and the first side 111 of the sleeping bag body 100 as a fulcrum, and the second extension portion 200b can be folded back in the Y' direction so as to overlap the sleeping bag body 100 with the boundary between the first extension portion 200a and the first side 111 of the sleeping bag body 100 as a fulcrum. In this case, the interval between the first extension portion 200a and the second extension portion 200b in the X-X' direction is larger than the width of the user's head in the X-X' direction (see FIGS. 5A and 5B). Thereby, with the user inside the sleeping bag body 100, the user's head is positioned between the first extension portion 200a and the second extension portion 200b before folding. With the user inside the sleeping bag body 100, the first extension portion 200a before folding may be arranged to be positioned on the Y-direction side with respect to the user's shoulder on the X-direction side, and the second extension portion 200b before folding may be arranged to be positioned on the Y-direction side with respect to the user's shoulder on the X'-direction side (see FIGS. 5A and 5B).

[0032] With the user inside the sleeping bag body 100, by folding back the first extension portion 200a and the second extension portion 200b, both shoulders of the user can be covered. The first extension portion 200a and the second extension portion 200b may be arranged on the Z'-direction side of the upper portion 120 of the sleeping bag body 100 in a state of covering both shoulders of the user after folding back so that the upper portion 120 overlaps (covers) the first extension portion 200a and the second extension portion 200b from the Z-direction side, or may be arranged to overlap (cover) the upper portion 120 of the sleeping bag body 100 from the Z-direction side.

[0033] The first part 210a of the first extension part 200a and the first part 210b of the second extension part 200b may be in contact with or overlap each other in a state where the first extension part 200a and the second extension part 200b are folded back. In this case, a window part W is formed between the first extension part 200a and the second extension part 200b. The first extension part 200a and the second extension part 200b can let the user's head protrude in the Y direction from the window part W in a state of covering both shoulders of the user after being folded back.

[0034] When the first engaging part 211a and the first engaging part 211b are provided, the first extension part 200a and the second extension part 200b are folded back, and in a state where the first part 210a of the first extension part 200a and the first part 210b of the second extension part 200b are in contact with or overlap each other, the first engaging part 211a and the first engaging part 211b are engaged with each other. Specifically, when the first engaging part 211a and the first engaging part 211b are a set of snap buttons, they are snapped together. When the first engaging part 211a and the first engaging part 211b are a set of hook-and-loop fasteners, they are connected to each other. When one of the first engaging part 211a and the first engaging part 211b is a substantially U-shaped hook or a substantially T-shaped toggle, and the other is a loop or a ring, the hook or the toggle is hooked on the loop or the ring. When one of the first engaging part 211a and the first engaging part 211b is a string, and the other is a loop or a ring, the string is tied to the loop or the ring. When the first engaging part 211a and the first engaging part 211b are strings, they are tied to each other. By engaging the first engaging part 211a and the first engaging part 211b with each other in this way, a state where the first extension part 200a and the second extension part 200b are folded back, and the first part 210a of the first extension part 200a and the first part 210b of the second extension part 200b are in contact with or overlap each other is maintained.

[0035] Further, the first extension portion 200a can be bent obliquely toward the X' direction side, and the second extension portion 200b can be bent obliquely toward the X direction side (see FIGS. 6A to 7B). In a state where the first extension portion 200a is bent obliquely toward the X' direction side and the second extension portion 200b is bent obliquely toward the X direction side, the first end 201a of the first extension portion 200a and the first end 201b of the second extension portion 200b are in contact with or overlap each other (see FIGS. 6A to 7B). In other words, the first extension portion 200a is bent obliquely toward the X' direction side and the second extension portion 200b is bent obliquely toward the X direction side so that the first end 201a of the first extension portion 200a and the first end 201b of the second extension portion 200b are in contact with or overlap each other. In this bent state, the fourth end 204a of the first extension portion 200a and the fourth end 204b of the second extension portion 200b are located on the Y direction side with respect to the first side 121 of the upper portion 120 of the sleeping bag body 100.

[0036] When the user is inside the sleeping bag body 100, the user can place their head on the first extension portions 200a and 200b bent as described above and use them as a pillow. Also, when the user is inside the sleeping bag body 100, the user can also put their head inside the first extension portions 200a and 200b bent as described above.

[0037] When the first engaging portions 211a, the first engaging portions 211b, the second engaging portions 221a, and the second engaging portions 221b are provided, the first extension portion 200a is bent obliquely toward the X' direction side and the second extension portion 200b is bent obliquely toward the X direction side so that the first end 201a of the first extension portion 200a and the first end 201b of the second extension portion 200b are in contact with or overlap each other. In this state, the first engaging portions 211a and the first engaging portions 211b are engaged with each other as described above, and the second engaging portions 221a and the second engaging portions 221b are engaged with each other in the same manner as the first engaging portions 211a and the first engaging portions 211b. Thereby, the state where the first extension portion 200a is bent obliquely toward the X' direction side and the second extension portion 200b is bent obliquely toward the X direction side so that the first end 201a of the first extension portion 200a and the first end 201b of the second extension portion 200b are in contact with or overlap each other is maintained.

[0038] Incidentally, all of the first engaging portions 211a, the first engaging portions 211b, the second engaging portions 221a, and the second engaging portions 221b can be omitted. Also, while the first engaging portions 211a and the first engaging portions 211b are provided, the second engaging portions 221a and the second engaging portions 221b can be omitted, and vice versa.

[0039] The sleeping bag S1 as described above exhibits the following first to third technical features and effects.

[0040] First Technical Feature and Effect A novel sleeping bag S1 is obtained in which at least one extension is connected to the edge of the opening of the sleeping bag body. This at least one extension can be used in various ways, such as being used as a pillow, or being folded back or folded by the user to cover the shoulders that are exposed from the opening during use.
