Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleeping bag with an improved fastener opening / closing portion.

[0002]

2. Description of the Related Art Generally, a fastener opening / closing part of a sleeping bag is shown in FIG.
As shown in (A), the belts 21 and 21 on both sides of the fastener are sewn to the front sides of the edges 12 and 12 on both sides of the bag body 10 which abut each other, with the engagement portion 21a outside. It has a configuration. By adopting such a configuration, when the fastener is closed, the band members 21 and 21 on both sides of the fastener are turned over as shown in FIG. Is folded into the back side of the bag 10. 22 is a fastener slider.

Recently, in order to increase the airtightness of the closing portion when the fastener is closed, the fastener strips 21 and 21 are attached separately from the edges 12 and 12 of the bag body 10 and It has also been practiced to increase the size of the part folded behind. This is called an air guard system or the like.

By the way, in the fastener opening / closing portion of the sleeping bag, the fastener slider often bites into the fabric of the bag when opening and closing. This is because the straps on both sides of the fastener are inverted when opening and closing, the slider is operated not only from the outside but also from the inside, and the fabric of the bag is very thin, etc. Is particularly noticeable when the fastener band is attached away from the edge of the bag, and the portion folded into the back of the bag is enlarged. Because
By attaching the fastener band away from the edge of the bag, the edge of the bag exposed inside the band becomes larger. For this reason, when the fastener band is attached away from the edge of the edge of the bag, a guard tape is often attached to the edge of the bag. This is called a shell guard system.

[0005]

In the case where the belt of the fastener is separated from the edge of the edge of the bag and the edge of the bag exposed on the inside of the fastener is covered with the guard tape, the outer edge of the guard tape is conventionally used. The guard tape was attached to the edge of the bag by sewing the part to the bag together with the fabric portion of the fastener band. As a result, the edge of the bag body exposed to the inside of the fastener is once covered with the tape, and the risk of the material of the edge being caught in the slider of the fastener is greatly reduced. However, since the inner edge of the guard tape is not fixed, the tape itself is bitten by the fastener slider. Therefore, the fact is that the biting frequency itself does not greatly change whether or not the guard tape is attached.

The present invention has been made in view of the above circumstances, and in order to increase the airtightness of a closed portion when the fastener is closed, the fastener band is attached to the end of the edge of the bag body. An object of the present invention is to provide a sleeping bag capable of effectively avoiding biting despite adopting the above-described configuration.

[0007]

The sleeping bag according to the present invention comprises:
Bands on both sides of the fastener are sewn on the front sides of both side edges of the bag body constituting the sleeping bag, with the meshing portions outside, and at least one of the sewn both side bands. The fastener opening / closing portion in which the edge of the bag is separated from the edge of the bag and the edge of the bag exposed to the inside of the band by the belt being separated from the edge of the edge of the bag is covered with guard tape. The outer edge of the guard tape is sewn on the fabric portion of the band, and the inner edge of the guard tape is sewn near the edge of the edge of the bag.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a sleeping bag 1 embodying the present invention.
FIG. 2 is a perspective view showing a fastener opening / closing portion of the example, FIG. 2 is a schematic sectional view showing a structure of a straight portion of the fastener opening / closing portion, FIG. 3 is a schematic sectional view showing a structure of a curved portion of the fastener opening / closing portion, and FIG. It is a perspective view which shows the whole structure of the sleeping bag.

As shown in FIG. 4, the sleeping bag is an envelope type in which two continuous sides of a rectangular bag 10 are used as fastener opening / closing portions 11.

As shown in FIGS. 1 and 2A, the fastener opening / closing portion 11 has strips 21 on both sides of a fastener 20 on front sides of edges 12 and 12 of the bag 10 which abut each other. 21 are sewn. Here, one of the strips 21 and 21 on both sides is separated from the end of the edge portion 12 of the bag body 10, and the other is located near the end of the edge portion 12 of the bag body 10. Also, in each of the belts 21, the meshing portion 21a faces the outside (the opposite side of the edge), and the fabric portion 21b faces the edge 1 of the bag body 10.
2 stitched.

A guard tape 30 is attached to the edge 12 to which the band 21 is attached away from the edge of the edge 12 of the bag 10 from the front side. The outer edge of the guard tape 30 is sewn to the edge 12 of the bag 10 together with the cloth 21b from above the cloth 21b of the band 21. The inner edge of the guard tape 30 is sewn to the cloth near the edge of the edge 12 of the bag 10. For this reason, there are two rows of sewn portions 40, 40 at the edge 12 to which the band 21 is attached away from the edge of the edge of the bag 10. Edge 12 mounted near the edge of 12
Has only one suture 40.

In the curved portion 11a of the fastener opening / closing portion 11, as shown in FIG. 3, the fastener 20 is formed by three-dimensional sewing in which the edge portion 12 of the bag body 10 is squeezed and sewn in the direction of the edge.
The structure is such that the band members 21 and 21 on both sides are raised.

More specifically, the belt 21 is formed of the bag 10.
The edge 12 mounted away from the edge of the edge 12 is bent substantially perpendicularly to the back side at the outer stitching portion 40.
Thereby, the band 21 attached to the edge 12 is
The engaging portion 21a stands up so as to face the front side. In addition, the edge 12 to which the band 21 is attached near the edge of the edge 12 of the bag body 10 is folded back and overlapped by the stitching portion 40, and the overlapped portion is further bent substantially perpendicularly to the back side. . As a result, the band 21 attached to the edge 12 rises with the engagement portion 21a facing the back side.

When the fastener 20 is closed in the fastener opening / closing section 11 having such a structure, that is, when the fastener 2 is closed.
When the engagement portions 21a, 21a of the belts 21, 21 on both sides are connected by the slider 22 of zero, the belts 21, 21 on both sides are turned over as shown in FIG. The edges 12, 12 are folded back.

Here, one of the strips 21 and 21 is
Away from the edge of the edge 12 of Therefore, the edge 12,
12 is folded greatly to the back side, and the other edge 12
The airtightness of the closing portion of the fastener 20 is enhanced by overlapping with the above. When the band 21 is separated from the end of the edge 12 of the bag 10, the edge 12 is greatly exposed inside the band 21,
Since the exposed portion is covered with the guard tape 30, the material of the exposed portion is not bitten by the slider 22. Moreover,
Since the inner edge of the guard tape 30 is sewn to the fabric near the edge of the edge 12 of the bag 10, the guard tape 3
There is less danger of the 0 being bitten by the slider 22.

Both the band members 21 and 21 are connected to the edge 1 of the bag body 10.
The guard tape 30 may be attached to the edges 12 and 12 on both sides apart from the end of the guard tape 3.
There is a high risk that 0 will be bitten by the slider 22. On the other hand, the airtightness of the closed portion of the fastener 20 is determined by the band members 21 and 21.
Are both separated from the edge of the edge 12 of the bag 10 and one is separated from the edge of the edge 12 of the bag 10. Therefore, it is desirable that one of the belts 21 and 21 be separated from the edge of the edge 12 of the bag 10 like the main sleeping bag.

The risk of the guard tape 30 being bitten by the slider 22 is generally higher in the curved portion 11a (see FIG. 4) than in the straight portion of the fastener opening / closing portion 11. But,
In this sleeping bag, the fastener 20 is bent at the curved portion 11a by three-dimensional sewing in which the edge 12 of the bag 10 is squeezed in the direction of the edge and sewn.
, The strips 21 and 21 on both sides are raised, so that the strips 21 and 21 can be smoothly inverted. Therefore, the risk of the guard tape 30 being bitten by the slider 22 does not particularly increase because of the curved portion 11a.

When the band 21 is separated from the end of the edge 12 of the bag 12, the rigidity of the three-dimensionally sewn portion decreases, but in the present invention, the band 21 is moved from the end of the edge 12 of the bag 12. Since the edges on both sides of the guard tape 30 are sewn to the separated edge portion 12, and two rows of sewn portions 40, 40 exist on the edge portion 12,
There is also an advantage that the rigidity of the three-dimensionally sewn portion is prevented from being reduced.

Although the sleeping bag is of an envelope type, it is needless to say that the sleeping bag can be applied to a wrap type.

[0020]

As described above, in the sleeping bag according to the present invention, when the zipper band is attached away from the edge of the bag, the edge is covered with the guard tape, and the guard tape is provided. Sew the outer edge of the on the fabric of the band,
Since the inner edge of the guard tape is sewn near the edge of the edge of the bag, there is less risk of the guard tape as well as the edge material being bitten by the fastener slider. Therefore, a high-quality sleeping bag excellent in both heat retention and operability is obtained.
