Description

  The present invention relates to a sleeping bag that wraps a sleeping human body, and more particularly, to a sleeping bag that does not allow a cold point and that can maintain a plump feeling without missing a filler.

  The sleeping bag was configured as shown in FIG. That is, the sleeping bag 100 has a plurality of storage portions 103 formed by stitching a top surface 101 and a lining 102 stacked one above the other at intervals, and the storage portions 103 are filled with feathers 104 as a filling material. It is a configuration.

However, the feathers 104 are easy to come off from the outer material 101 and the lining material 102, and when the filling amount is small, bias is likely to occur. In addition, since the feathers 104 do not enter the narrow space positively, they tend to harden at a position away from the seam 105 as indicated by a virtual line in FIG. For this reason, a cold point where cold air enters can be formed at the seam 105 portion between the storage portions 103. There is no plump feeling in the vicinity of this part,
In order to eliminate such a cold point, the sleeping bag of the following patent document 1 was proposed.

  As shown in FIG. 6B, the sleeping bag 106 has the outer surface 101 and the lining 102 on the front surface of the sheet-shaped heat insulating material layer 107 and the lining 102 on the back surface, respectively. A plurality of storage portions 103 are formed by shifting the sheet-like heat insulating material layer 107 so that the seams 105 do not match, and forming a plurality of storage portions 103, and the storage portions 103 are filled with feathers 104.

  However, since it is the feather 104, the difficulty that it is easy to come off remains. In addition, although a cold point is not possible, the sheet-shaped heat insulating material layer 107 needs to have a certain thickness, and since the structure has the storage portions 103 alternately on both sides, the thickness is increased and the weight is increased. Will also be heavy. This is inconvenient for the sleeping bag 106 that is required to be compact and lightweight.

  Further, in the sleeping bag 100 configured as shown in FIG. 6A, the storage portion 104 of the sleeping bag 100 is usually formed in an elongated shape, and therefore, when pulled in a direction perpendicular to the longitudinal direction, the outer material 101 and the lining material 102. Although it does not stretch itself, the sleeping bag 100 is deformed in the extending direction, and the feather 104 in the storage unit 103 is compressed by this deformation. That is, it is not only compressed by the load of the human body, but also compressed when pulled. And even if the feather 104 is compressed due to the deformation that stretches, the feather 104 will not move to the part where the cold point can be made, so even in the use state where the human body has entered, the part where the weight is not applied is also compressed. You may feel the cold point problem noticeably.

  In the sleeping bag 106 configured as shown in FIG. 6B, a cold point is basically not possible. However, when the outer material 101 and the lining material 102 are pulled and deformed in the extending direction, the portion that is not weighted is close to being compressed as described above. In addition, the plump feeling is easily lost in combination with the missing feathers 104.

Japanese Utility Model Publication No. 62-20570

  Therefore, the main object of the present invention is to be thin and light, have no cold points, and maintain a plump feeling.

  Means for this is a sleeping bag having a plurality of storage portions in the portion sandwiched between the outer and the lining, and filled with a filling in these storage portions, all the storage portions are elongated in the same direction These storage portions are divided so that another storage portion is adjacent above or below in the thickness direction between adjacent storage portions in a longitudinal cross-sectional shape in a direction perpendicular to the longitudinal direction of the storage portions. As long as the filler is a long-fiber cotton made of aligned long fibers, the long-fiber cotton has a longitudinal direction of the long-fiber cotton and a longitudinal direction of the storage portion coincide with each other. It is a sleeping bag stored in.

  In this configuration, the elongated storage portions are arranged so as to partially overlap and complement each other in the thickness direction, and there is no need for a seam that passes through the outer material and the lining material together, and there is no cold point where cold air enters. And the filling material accommodated in each accommodating part exists alternately around the seam part which fixes a partition, and heat-retains and supports a load.

  Long-fiber cotton as a filler is present in a state where the longitudinal direction is aligned with the elongated storage portion. By being stored so as to extend from end to end of the storage unit, the long fiber cotton plays a role of supporting heat retention and load evenly in the entire longitudinal direction of the storage unit, and does not come out of the storage unit. In addition, since the direction in which the long fiber cotton extends is the same as the direction in which the storage portion extends, the long fiber cotton can also function at the relatively end of the storage portion.

  According to this invention, since it has the accommodating part arrange | positioned alternately, it does not have a cold point. In addition, since the storage part is made into an elongated shape and the filling made of long fiber cotton aligned so as to extend in the longitudinal direction is stored, the long fiber cotton can be spread to the corners of the storage part. In addition, since there is no missing like feathers, you can maintain a plump feeling.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a cross-sectional view of a part of the sleeping bag 11, and FIG. 2 is a front view showing the entire sleeping bag 11.

  As shown in these drawings, a plurality of storage portions 14 are provided in a portion sandwiched between the outer surface 12 and the lining 13, and the storage portions 14 are filled with a filler 15.

  As shown in FIG. 1, the storage portions 14 are all formed in an elongated shape that is long in the same direction. The length direction of the storage portion 14 is the same as the longitudinal direction of the sleeping bag 11.

  In this example, the Mommy sleeping bag 11 is illustrated, but the same applies to sleeping bags such as an envelope type, a wrap type, and a two-legged independent type.

  FIG. 1 shows a cross-sectional structure obtained by cutting the storage portion 14 in a direction orthogonal to the longitudinal direction. As shown in this figure, the storage portion 14 has a flexible sheet-like partition 16 separated so that another storage portion 14 is adjacent above or below in the thickness direction between the storage portions 14 adjacent in the left-right direction. Arranged. That is, in the cross section in the direction perpendicular to the longitudinal direction of the storage portion 14 between the outer material 12 and the inner material 13 that are arranged in parallel with a gap in the vertical direction, the outer material 12, the inner material 13, the outer material 12, the inner material 13, and the zigzag It has the partition 16 of the shape joined and extended in order. The joining of the partition 16 to the outer material and the lining material 13 is performed by sewing. In the figure, reference numerals 12a and 13a denote stitches.

  The partition 16 has a space that is not pulled by the outer material 12 or the lining material 13 even when the outer material 12 and the lining material 13 are stretched in a direction perpendicular to the longitudinal direction of the storage portion 14. In other words, the length of the partition 16 extending in a V-shape or an inverted V-shape between the seams 12a and 13a in the outer fabric 12 or the lining 13 is more filled with the filling than the length between the adjacent seams 12a and 13a. It is set to be long even if it is taken into consideration.

  The partition 16 is made of a mesh fabric, but other appropriate fabrics and nonwoven fabrics can be used. It is desirable that the partition 16 is thin and light.

  FIG. 3 is a cross-sectional view showing a specific configuration of the partition 16. That is, the outer surface 12 and the lining 13 provided with these are sewn to the outer material 12 and the lining material 13 so that the intermediate positions in the width direction of the partition carrier 16a having a belt shape are arranged in parallel at a predetermined interval. As shown by the phantom lines, they are integrated by joining the side edges in the width direction of the partition carrier 16a. This joining is also performed by sewing.

  The size in the width direction of each storage portion 14 may be basically set to the same size except for the storage portions 14 located at both ends in the width direction, and the size is appropriately determined according to the performance required for the sleeping bag. Is set.

  As the filling 15 filled in the storage unit 14, long fiber cotton 15a made of long fibers is used, and as shown in FIG. 4, a large number of long fiber cottons 15a are stored in an aligned state. The length of the long fiber cotton 15a to be stored is the length from the end to the end of the storage portion 14 in the longitudinal direction. That is, the storage of the long fiber cotton 15 a is performed so that the longitudinal direction of the long fiber cotton 15 a coincides with the longitudinal direction of the storage unit 14. And the both ends of the longitudinal direction of the accommodated long fiber cotton 15a are fastened together when the outer material 12 and the lining 13 are stitched together and the edge is closed. The number of the long fiber cottons 15a to be aligned is appropriately set according to the desired thickness of the sleeping bag 11.

  The long fiber cotton 15a is used in a state in which the flower yarn is integrated with the core yarn and the flower yarn protrudes all around the core yarn. Specifically, “Air Flake” (registered trademark) manufactured by Kurashiki Boseki Co., Ltd. is preferable. This is because “Air Flake” is lightweight and soft, has good heat retention, and is excellent in resilience after being compressed.

  The sleeping bag 11 (see FIG. 2) having the above-described parts has the following operational effects. In FIG. 2, 17 is a slide fastener.

  The outer material 12 and the lining 13 have seams 12 a and 13 a for sewing the partition 16, but the seams 12 a and 13 a do not penetrate the outer material 12 and the lining 13. For this reason, since there is no cold point, it is possible to suppress the entry of cold air.

  Moreover, since the accommodating part 14 which accommodates the long fiber cotton 15a is alternately arrange | positioned through the partition 16 in the thickness direction, the long fiber cotton 15a centering on the said seams 12a and 13a part for attaching the partition 16 is carried out. Therefore, the influence of cold air from the seams 12a and 13a can be suppressed as much as possible.

Moreover, since the longitudinal direction of the long fiber cotton 15a coincides with the longitudinal direction of the storage portion 14, the linear long fiber cotton 15a is extended to every corner of the storage portion 14 (in the width direction and the longitudinal direction of the storage portion 14). From end to end). In addition, since the long fiber cotton 15a has a length from end to end in the longitudinal direction of the storage portion 14, the length of the long fiber cotton 15a, which is a so-called wire, can be used to prevent unnecessary bias, and in the thickness direction. It is also possible to obtain a state in which the long fiber cottons 15a in the adjacent storage portions 14 overlap each other, and a plump feeling can be obtained at the end in the width direction of the storage portions 14.
In other words, unlike the case where feathers as points are used as the filling material, the high-performance sleeping bag 11 does not come out of the filling material.

  Further, since the thickness of the sleeping bag 11 is determined by the number of long fiber cottons 15a to be filled, the thickness can be easily managed. This effect can be enhanced by the configuration in which the partition 16 is formed by joining the partition carriers 16a so that the size of the storage portion 16 can be easily kept uniform during the sewing operation.

  In addition to the filling, in the case of feathers, it is necessary to blow feathers at the time of filling, but in the case of long fiber cotton 15a, since it is long, for example, it is filled by sliding it into a cylinder. Therefore, work is easy and deterioration of the work environment is also suppressed.

  Since the long fiber cotton 15a is formed by integrating the flower yarn into the core yarn and has an excellent feeling of plumpness, the load is flexibly supported as shown by the phantom line in FIG. And since the length of the partition 16 is given a margin, even if the outer surface 12 is deformed, the lining 13 is not deformed via the partition 16 only by that.

  Even if the outer surface 12 and the lining 13 are pulled in a direction (width direction) orthogonal to the longitudinal direction of the storage portion 14, no external force is applied to the internal partition 16 or the long fiber cotton 15a. That is, even if the outer material 12 and the lining material 13 are pulled, the long fiber cotton 15a is not compressed by that.

  For this reason, in addition to when a load is applied to the long fiber cotton 15a, the compression force does not act unnecessarily, and the long fiber cotton 15a moves unexpectedly in a direction away from the end in the width direction of the storage portion 14. This can be suppressed and a desired function can be performed.

  Moreover, since the partition 16 surrounding the long fiber cotton 15a is made of mesh, it is lightweight and obtains a desired effect by restricting the movement of the long fiber cotton 15a by contact resistance with the long fiber cotton 15a. It is done.

  The above is one form for implementing this invention, This invention is not limited to the said structure, Other structures can also be employ | adopted.

  For example, in the above-described configuration, the storage portion has two layers, but the partition shape can be changed to have three or more layers.
