  In patent document 1, when sealing the circumference | surroundings of a user's face part with the periphery of the opening part of a sleeping bag, it is an opening edge and pulls the string provided in the part equivalent to a user's forehead side and chin side. The periphery of the opening is shortened. Therefore, even if the forehead and chin side straps are pulled, the opening becomes a horizontally long shape, the interval between the user's forehead and the chin is immediately narrowed, and the lateral interval corresponding to the cheek is widened. It will not be possible to seal well.

  Moreover, in patent document 2, although the string provided in the periphery of the opening part of a sleeping bag and the string provided in the direction away from this periphery are pulled, the circumference of a face part is sealed, but two strings are pulled. In addition, the operability is bad, and even if both strings are pulled, it is very difficult to narrow the periphery of the face portion according to the shape of the face portion.

  In view of the above problems, an object of the present invention is to provide a sleeping bag that can effectively seal around the face portion of the user of the sleeping bag.

  In order to achieve the above object, according to the present invention, the peripheral portion of the opening that can expose the face portion of the user is maintained in a shape similar to the shape of the face portion of the user.

  Specifically, the first invention has a sleeping bag main body that accommodates a user's body part, and a sleeping bag head that accommodates the user's head part above the sleeping bag main body, A sleeping bag having an opening at the head of the sleeping bag capable of exposing the face portion of the user, wherein the periphery of the opening extends from the lower end of the opening in both the left and right directions of the sleeping bag and then obliquely upward It is formed so as to extend in a curved shape and are integrally connected, and is provided with changing means capable of changing the width of the opening at the periphery of the opening, and inside the sleeping bag provided with the changing means, A face pad portion that can contact the face portion of the user is provided along the peripheral edge.

  According to a second invention, in the first invention, the sleeping bag body is provided with a body fastener that slides from the lower end of the opening toward the feet of the sleeping bag body to open and close the sleeping bag body. The main body fastener includes a sheet-like base material sewn on the sleeping bag main body, and a plurality of meshing elements and sliders attached to the sheet-like base material.

  According to a third invention, in the second invention, the changing means is formed of an opening fastener integrally continuous with the main body fastener, and the slider of the main body fastener slides also on the opening fastener. The width of the opening can be changed.

  FIG. 3 is an enlarged perspective view of the upper part of the sleeping bag of FIG. 1, and FIG. 4 is an enlarged perspective view for explaining the opening fastener. In FIG. 4, in order to easily explain the opening fastener, the face pad portion 21 is omitted from FIG. 3.

  As shown in FIG. 3, the sleeping bag head 5 is provided with a vertically long oval opening 10 that can expose the face portion F of the user N. The peripheral edge 11 of the opening 10 is formed so as to extend from the lower end portion 10a of the opening 10 in both the left and right directions of the sleeping bag 1 and then extend obliquely upward in a curved shape and integrally connected. The lower part from the lower end part 10a of the opening part 10 will be described as a sleeping bag body part 4 and the upper part thereof as a sleeping bag head part 5 for distinction. That is, basically, the sleeping bag body 4 and the sleeping bag head 5 are integrated without being distinguished, and there is no clear boundary between the sleeping bag body 4 and the sleeping bag head 5, but the opening 10 The position is distinguished as described above for the sake of convenience in explaining the position.

  A body fastener 6 that slides in the foot direction of the sleeping bag body 4 from the lower end 10a of the opening 10 to open and close the sleeping bag body 4 is provided at the center position in the left-right direction of the sleeping bag body 4. The main body fastener 6 is provided with a slider 7 including an upper slider 7a and a lower slider 7b. By sliding the upper slider 7a downward in the sleeping bag and opening the hanging portion 3 to the left and right, the user N can enter and leave the space K between the laying portion 2 and the hanging portion 3, while the upper slider 7a is moved upward in the sleeping bag. The body part of the user N is wrapped by closing the hanging part 3 by sliding it.

  As shown in FIG. 4, an opening fastener 12 is provided on the peripheral edge 11 of the opening 10 as a changing means capable of changing the width (size) of the opening 10. Although details will be described later, the opening fastener 12 is provided as an integral fastener continuous with the main body fastener 6.

  By aligning the positions of the lower end portion 10a of the opening portion 10 and the upper end portion 6a of the main body fastener 6 with the opening portion fastener 12 of the opening portion 10 and the main body fastener 6 being continuously provided, the upper slider 7a is provided.

As a result, the user N can enter and exit smoothly at a small entrance and exit portion. In addition, since it is better not to open the hook part 3 as much as possible as long as the body fastener 6 has no trouble for the user N to enter and exit, it is assumed to be halfway in the foot direction, but in some cases, at the foot position of the sleeping bag 1 A certain sleeping bag lower part 4a may be provided.

  A face pad portion that can contact the face portion F of the user N along the peripheral edge 11 of the opening 10 on the inner side 1a of the sleeping bag (the inner side 3a of the hanging portion 3) than the opening fastener 12 provided on the peripheral edge 11. 21 is provided. The face pad portion 21 is formed into a bag shape having batting inside, and is sewn and integrated with the peripheral edge 11 of the opening 10. Actually, as shown in FIGS. 1 and 2, the face contact portion 21 is exposed from the opening 10 to the outside 3 b of the hanging portion 3, so that the touch to the face portion F is soft touched. Can be. At the same time, by providing the face pad portion 21, it is possible to prevent an unpleasant feeling when the opening fastener 12 directly contacts the face portion F and to have a cushioning property. The face rest part 21 becomes a hood with rising, and the face part F can be softly wrapped.

  The detailed structure of the opening part 10 is demonstrated based on FIGS.

  The main body fastener 6 includes a slider 7, a meshing element 8, and a sheet-like base material 9. The opening fastener 12 includes one sheet-like base material 9 that is continuous with the sheet-like base material 9 of the main body fastener 6 and a meshing element 13. That is, the sheet-like base material 9 of the main body fastener 6 and the opening fastener 12 is sewn from the lower end portion 6b to the upper end portion 6a at the end of the hook portion 3 on the left side (FIGS. 1 and 2), and then the opening portion 10 is sewn. The left side lower end portion 10a of the left side lower end portion 10a is bent along the left edge 11 and sewed along the peripheral edge 11, and then sewn along the peripheral edge 11 formed so as to draw an ellipse. It turns and is sewed symmetrically along the peripheral edge 11 and returns to the right lower end 10a of the opening 10, and then the upper end of the main body fastener 6 at the end of the hook 3 on the right (FIGS. 1 and 2). It is sewn from the part 6a to the lower end part 6b. The upper end portion 6a of the main body fastener 6 and the lower end portion 12a of the opening portion fastener 12 are coincident with each other, and the meshing element 8 and the meshing element 13 are continuously attached to one sheet-like base material 9 at the same interval. The slider 7 of the main body fastener 6 can slide the meshing element 8 and the meshing element 13 continuously.

  Note that, from the lower end portion 6b to the upper end portion 6a of the main body fastener 6, the left and right sheet-like base materials 9 and the left and right meshing elements 8, 8 face each other. However, since the peripheral edge 11 of the opening 10 extends from the lower end 12 a of the opening fastener 12 in the left-right direction of the sleeping bag 1, the left and right sheet-like base materials 9 are away from each other. In this case, since the meshing element 13 is maintained at the same fixed interval as the meshing element 8, the sheet-like base material 9 is bent and spreads left and right. As a result, the meshing elements 8 and 8 move from the state where the ends of the left and right sheet-like base materials 9 face each other to the state where the inner side surfaces 9b and 9b face each other, that is, from the meshing elements 8 and 8 to the meshing element 13. From the state of facing each other, the direction is gradually changed so that the meshing elements 13 are juxtaposed with each other. In addition, when the sheet-like base material 9 changes direction and bends, the upper end of the meshing elements 8 and 8 and the lower end of the meshing element 13 are gradually changed in direction and smoothly changed. In addition, 9a is an outer surface of the sheet-like base material 9.

  As a result, the meshing element 13 faces the sleeping bag outer side 1b (the outer side 3b of the hanging portion 3). In this orientation, the sheet-like base material 9 and the meshing element 13 return to the lower end portion 10a of the opening portion 10 around the peripheral edge 11 of the opening portion 10, and the sheet-like base material 9 is sewn to the peripheral edge 11 of the opening portion 10. Become so. In the main body fastener 6, the sheet-like base material 9 and the meshing element 8 face each other on the left and right sides. On the other hand, the sheet-like base material 9 is in a state in which the inner side surface 9b facing the inner side 1a of the sleeping bag 1 gradually changes its direction at the peripheral edge 11 of the opening 10 and changes its direction approximately 90 ° accordingly. The meshing element 13 is also sewn to the peripheral edge 11 while gradually changing the direction toward the sleeping bag outer side 1b. Thereby, the opening 10 is easily maintained in a smooth vertically long elliptical shape by changing the direction of the meshing element 13.

  Further, when the slider 7 is slid so as to move from the meshing elements 8 and 8 to the meshing element 13 in order to change the size of the opening 10, the left and right meshing elements 13 and 13 are moved closer to each other or oriented. It is possible to move by changing them to face each other or sliding them with a little strong force. By this operation, the width of the opening 10 can be changed. By sliding the upper slider 7a to the upper part of the sleeping bag 1, the meshing elements 13, 13 are joined together from the portion near the lower end portion 10a of the opening portion 10, so that the upper end portion of the opening portion 10, that is, the forehead portion of the face portion F Is not pulled in the direction of the lower end portion 10a of the opening 10, that is, the jaw portion of the face portion F, the opening 10 is not widened horizontally, and a small vertically long elliptical shape is formed. Even when the size of the opening 10 is changed, the sealing performance around the face can be maintained high.

  The sleeping bag lower portion 4a at the foot position of the user N is provided with a foot fastener 16 that opens the sleeping bag lower portion 4a in a semicircular shape. By opening the sleeping bag lower portion 4a with the foot fastener 16, the feet can be ventilated, or the feet You can also go out to sleep. The sleeping bag main body 4 is provided with a hand opening 17 through which both hands (not shown) of the user N are put in and out. The hand opening 17 can be opened and closed with a hand fastener (not shown). Even when the main body fastener 6 of the hook 3 is closed, the hand can be freely moved out of the hand opening 17.

  As shown in FIGS. 2, 7, and 8, the cold protection back edge 20 for the main body is disposed on the inner side of the sheet-like base material 9 on the left side (FIGS. 1 and 2) of the main body fastener 6 of the sleeping bag main body 4. Yes. The cold protection back edge 20 for the main body prevents the passage of the gap air when the left and right engagement elements 8, 8 of the main body fastener 6 are engaged with each other, and is formed in a bag shape having batting, and the left side of the main body fastener 6. It is sewn to the hook 3 at the end. Further, a biting prevention piece 22 for preventing biting of the meshing elements 8, 8 of the main body fastener 6 is sewn to the hook portion 3 between the left meshing element 8 and the main body cold protection back edge 20.

  In addition, although the cold insulation back edge 20 for main bodies and the biting prevention piece 22 were provided only in the left engagement element 8, you may provide in the right side instead of the left side, or you may provide in both sides.

  As shown in FIGS. 2 to 6, the face pad portion 21 is provided integrally with the main body cold protection back edge 20 in the same size. The cold protection back edge 20 for the main body is a measure for preventing a crevice wind when the meshing elements 8 and 8 are engaged with each other, and the face pad portion 21 is a measure for preventing the cold around the face portion F so as to prevent the air from flowing. Since they are common in preventing leakage, they are formed in the same size. However, the cold insulation back edge 20 for the main body is a measure for preventing the gap air between the meshing elements 8 and 8 and does not have to be a large bag body, but the face pad 21 provides a sealing property between the face portion F and the opening. Since it is a thing to raise, it is set as a bag body a little larger than the cold protection back edge 20 for main bodies, and may also increase a batting inside. The face pad portion 21 is provided along the peripheral edge 11 from the lower end portion 10a of the opening portion 10 continuously to the cold protection back edge 20 for the main body, returns to the lower end portion 10a of the opening portion 10 and engages with the other of the main body fastener 6. It extends to a part of the element 8 so that the sealing around the face portion F can be ensured. The face pad 21 is not limited to the structure of this embodiment. For example, after the face pad 21 returns to the lower end 10 a of the opening 10, the other engagement element 8 of the main body fastener 6 is used. It is provided as a free extension part extending to a part of (not extending to the hook part 3 and extending in a belt-like manner), and the peripheral edge 11 of the opening part 10 is wound around to provide a sealing property. It may be further increased.

  Next, a state when the user N enters the sleeping bag 1 will be described.

  The sliders 7 a and 7 b of the main body fastener 6 are lowered in the direction toward the lower end portion 6 b to open the hanging portion 3 to the left and right, and the body part of the user N is inserted into the space K between the hanging portion 3 and the laying portion 2. Thereafter, the face pad 21 is made to jump out from the peripheral edge 11 of the opening 10 to the sleeping bag outer side 1b. And the slider 7a of the main body fastener 6 is slid to the upper end part 6a, and the sleeping bag main-body part 4 is closed. At this time, when the slider 7a is slid in the direction toward the upper end 6a, the direction of the meshing element 13 of the opening fastener 12 and the sheet-like base material 9 is different from that of the main body fastener 6 at the lower end 10a of the opening 10. Therefore, the slide resistance of the slider 7a temporarily increases or stops at the upper end 6a (that is, the lower end 10a of the opening 10). As a result, the slider 7a is not suddenly closed to the face portion F, and the slider 7a can be quickly and safely slid upward without requiring much attention. If the size of the face of the user N is a general size, this state may be used. However, when the face of the user N is a small face or a small head, the face portion is adjusted to the user N. If it is desired to reduce the size or reduce the exposure around the face portion F to prevent cold, if the slider 7a staying at the lower end 10a of the opening 10 is further lifted, the meshing elements 13, 13 opened to the left and right are meshed. The opening 10 can be narrowed. If the slider 7a cannot be lifted smoothly by this operation, the slider 7a can be operated smoothly by pulling up the slider 7a after bringing the meshing elements 13, 13 of the opening fastener 12 close to each other in the left-right direction. it can. Then, the face contact portion 21 is positioned between the face portion F and the slider 7a so that the slider 7a does not hit the face portion F. This operation can be performed using both hands inside the face portion F, and can also be performed by taking both hands out from the hand opening 17.

  If the slider 7a of the opening fastener 12 is pulled up to the upper end, the opening 10 can be fully closed. By moving the slider 7a, the size of the opening 10 can be finely adjusted between the position of the lower end 10a of the opening 10 and the upper end (a state in which the opening 10 is fully closed). Can be adjusted to the user's preferred size. When the fully closed state is established, the meshing element 13 has a loop shape at the upper end, so that the slider 7a does not come off.

  Then, when it is desired to largely expose the face portion F or to exit the sleeping bag 1, the slider 7a may be slid in the opposite direction. Further, not only the slider 7a but also the slider 7b can be slid in the direction of the upper end portion 6a so that the hanging portion 3 around the trunk of the user N can be opened. The slider 7b can be omitted.

  In the embodiment, the peripheral edge 11 of the opening 10 has a vertically long elliptical shape extending obliquely upward from the lower end 10a of the opening 10 in both the left and right directions, but is not limited to the shape of this embodiment. . In the present invention, when the size of the opening 10 is changed, the size may be changed so that the gap does not appear in the cheek portion of the face portion F, and the shape of the opening 10 is It is preferable that the size can be changed in a shape that matches the shape of the face portion F. For example, a vertically long oval shape, a substantially egg shape, a substantially soybean shape, a substantially triangular shape, or the like can be used.

  In particular, the opening fastener 12 that is a changing means capable of changing the width of the opening 10 is preferably changeable so that the width of the opening 10 matches the shape of the face portion F, and a vertically long elliptical shape is preferable.

  In the present embodiment, the periphery of the face portion F can be sealed by the opening 10 and the face pad portion 21 so that it is possible to take measures against the cold. Therefore, the inner portion 1a of the sleeping bag 1 corresponds to the shoulder portion of the user N as a measure against the cold. It is no longer necessary to squeeze the shoulder warmer (not shown) that has been conventionally provided at the position to take measures against the cold. In other words, it is no longer necessary to squeeze the shoulder warmer while going to bed at the cold. Since it takes a considerable amount of time to operate the shoulder warmer, the omission of this operation is very useful. Further, in the present invention, even if it is not separately prevented that warm air below the shoulder escapes, the air does not escape from around the face portion F, so that the warmed air is protected and not escaped from the entire sleeping bag. it can. As a result, the shoulder warmer can be omitted in some cases. The cold protection measures include both measures that external cold air does not enter and measures that prevent warm air inside the sleeping bag from leaking outside.

(Other embodiments)
In the present embodiment, the sleeping bag 1 is shown as a so-called mummy type, but is not limited to this, and may be another shape such as a so-called envelope type or a shape closer to a square.

  Moreover, in this embodiment, although the main body fastener 6 of the hanging part 3 was provided in the substantially center position of the width direction of the sleeping bag 1, it does not necessarily need to be a center position, and is provided shifted | deviated from the center position to right and left. Also good.

  Moreover, although the face pad part 21 is extended and formed integrally with the cold protection back edge 20 for main bodies, you may make it provide separately instead of integral.

  In the embodiment, the opening fastener 12 is integrated with the main body fastener 6, but may be a separate body. However, as in the above embodiment, the opening fastener 12 integrated with the main body fastener 6 is preferable in terms of the functional effects described in the embodiment, and thus is preferable.

  Further, although the opening fastener 12 is used as a changing means for changing the size of the opening 10, the opening fastener 12 is not limited to this. For example, it may be a fitting groove and a protrusion made of resin or metal unevenness, and can be expanded and contracted. A core rod such as rubber may be used.

  Moreover, in the said embodiment, although the main body fastener 6 and the opening part fastener 12 were comprised with the sheet-like base material 9 of one sheet, normally two sheet-like base materials are sewn separately on either side, The fastener 6 and the opening fastener 12 may be used. In this case, at the position of the upper end portion of the opening 10, both sheet-like base materials are provided with stoppers (not shown) for the meshing elements so that the two sheet-like base materials are fastened. Is preferred. Moreover, in order to maintain the opening part 10 in a smooth vertically long elliptical shape, the front end sides of the fasteners may be sewn together so as to be integrated.
