Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a school bag.

[0002]

2. Description of the Related Art Conventionally, a school bag is designed to be used only as a backpack bag, and both ends of the handle band can be fixed to the upper end fixing portion of a backpack band so that it can be used as a carrying bag. What has been made is proposed.

That is, as shown in FIG. 6, the one using the above-mentioned conventional handle band is provided with a tack 4, at the center of the upper portion of the back plate 1.
When the back strap connecting rings 5 and 5 to be tacked at 4 are tacked, both ends of the handle band 3a are tacked to the back plate 1 by the tacks 4 and 4.

[0004]

[Problems to be Solved by the Invention] Since the school bag is free to use both hands when commuting to school, it is safe and convenient for children to go to school, and has been supported in Japan for many years. However, children's body size has recently become large, and in a crowded environment, the school bag on their back often hits other people, which is an obstacle, and it is sometimes convenient to carry it with you temporarily.

However, in the lower grades of elementary school, the stored items are relatively small, but in the upper grades, the stored items increase and become considerably heavy. Therefore, in order to hold a heavy school bag in the hand, it is necessary to provide a considerably strong handle, and the conventional handle band as shown in FIG. 6 has a problem that it is not strong enough and is not reliable. Was.

Of course, the above problem can be solved by selecting the material, thickness, etc. of the handle band, but if a too large and strong handle band is attached to the main body of the school bag, the problem will occur.

Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a school bag having a durable handle attached in a good appearance.

[0008]

In order to solve the above-mentioned problems, in order to solve the above-mentioned problems, the structure of the present invention, which is based on the above-mentioned claims, meets the above-mentioned object. In the school bag having the end edges sewn together, the handle hole 3 bulges upward in a mountain shape having the same width as the cover 2 and the upper side being the center.
The handle plate 3 having 1 is folded back at its lower side portion 32 into a U shape to show the base end side portion of the cover lid 2, and together with the cover lid 2, a sewing thread 6 is provided on the upper edge portion of the back plate 1. This is a technical means characterized by stitching.

[0009]

Next, the operation of the present invention will be described. Since the handle plate 3 of the present invention has the lower side thereof sewn to the back plate 1 with the sewing thread 6 over the entire width, the connecting portion between the handle plate 3 and the back plate 1 is point-joined by the conventional tacks 4 and 4. Instead, the sewing thread 6 acts as a line joint, and the connecting portion is strong without damage.

Further, since the width of the handle plate 3 is substantially the same as the width of the back plate 1 and the cover lid 2, the grip plate 3 has the function of maintaining a sense of unity with them and improving the appearance.

EXAMPLES Next, examples of the present invention will be described. 1 in the figure
Is the back plate of the school bag. As the back plate 1, a conventionally well-known one can be used, but in this embodiment, a cushion member is used so that it is in close contact with the user's back when carrying the back.

That is, the back plate 1 shown in the drawing has a cushion material 13 interposed between the substrate 11 and the back plate material 12, as shown most clearly in FIG. The cushion material 13 is composed of two layers of a relatively hard lower cushion material 131 such as Styrofoam and a relatively soft upper cushion material 132 such as sponge foam synthetic resin.

As shown most clearly in FIG. 5, the lower cushion material 131 is formed in a substantially U-shape in a plane so as to contact both side portions and a lower portion of the substrate 11, and the both sides of the U-shape are in contact with each other. The upper and lower portions of the surface portion are thick portions 131a, 131a
The upper and lower central portions are formed to be thin portions 131b, and are adapted to substantially match the curve of the user's back in the length direction. Further, the U-shaped lower side surface portion of the lower cushion material 131 has thick portions 131a, 131 on both left and right sides.
It is formed so as to be a and the central portion on the left and right sides is a thin portion 131c so as to be substantially adapted to the curve of the user's back in the girth direction. It is needless to say that the lower cushion material 131 may be divided into a plurality of pieces for convenience of manufacturing.

The upper cushion material 132 has a constant thickness and is stacked so as to cover the upper surface of the lower cushion material 131. Then, the back plate material 12 is covered on the upper cushion material, and the back plate material 12 is sewn on the substrate 11 along the edges of the lower cushion material 132 and the upper cushion material 131 (FIG. 1). See)). At the time of this stitching, the upper cushion material 132 is compressed to some extent, and due to the elasticity of the backboard material 11 and the restoring force of the upper cushion material 132, the backboard material 11 is restored.
Is curved with a gentle curved surface so that the difference in thickness of the lower cushion material 131 is smoothed and appears on the outer surface side of the back plate material 11.

A relatively soft central cushion material 133 such as a sponge-like foamed synthetic resin is provided in an empty space surrounded by the upper cushion material 132 and the lower cushion material 131. If the part where the central cushion material 133 is arranged is in close contact with the user's back, it may cause sweat on the back in summer when the temperature is high. It is desirable to maintain a certain interval to ensure air permeability. However, since the school bag is used from the lower grades when the body is not sufficiently developed, it is difficult to prevent the user's back from coming into contact with this part at all. Even if the back comes into contact, it has a buffering effect. In addition, this central cushion material 1
33 is a lower cushion material 131 and an upper cushion material 13
2 has a constant gap, and the back plate material 12 is sewn to the base plate 11 with the suture thread 7a in the U-shaped gap portion shown in FIG. As a result, an air passage is secured to prevent back stuffiness.

The upper edge of the back plate 1 is covered with a lid 2
It is the same as the conventional one that the base end edge of is sewn. At the center of the upper part of the back plate 11, the backpack belt connecting rings 5 and 5 are tacked by tacks 4 and 4 (not shown, but the backpack belt connecting rings 5 and 5 are fixed to the backpack belt connecting ring called manju). It is held by metal fittings and tacked.) The backing cloth 8 shown in FIG. 1 is for concealing the backpack belt connecting ring fixing metal fitting.

Reference numeral 3 denotes a handle plate 3 which is a main part of the present invention. The handle plate 3 has a handle hole 3 which is substantially the same in width as the cover 2 and has an upper side in the center and an upward bulging handle hole 31. The bottom side 32 of the cover 2 is folded back in a U shape to show the base end of the cover 2, and the upper cover 2 and the back plate 1 are sewn together with a sewing thread 6.

The grip plate 3 is preferably made of the same material as the main body of the school bag, and is cut into a shape having a grip hole 31 which is substantially the same width as the cover lid 2 and has an upper side in the center and an upward bulge. Although one may be used, in this embodiment,
In order to secure the strength and improve the appearance, two sheets of the outer material 3A and the inner material 3B are stacked and used. That is, since one side of the natural leather or artificial leather used for the satchel is usually dyed and finished, two sheets of the outer fabric 3A and the inner fabric 3B are laminated with the finished surfaces facing outward.

The outer surface 3A and the inner lining 3B are double-layered, and the upper edges of the outer lining 3A and the inner lining 3B are folded back inward and overlapped with each other and sewn with a sewing thread 9a. The handle hole 31 of each of the
A and the lining 3B have the sewing thread 9b even at the peripheral edges of the handle holes 31.
Sutured with.

Further, the cover material 3 extends over the upper side of the outer material 3A and the lining 3B and the upper sides of the handle holes 31, 31.
3 is wound, and a handle cushion material 34 is interposed inside the cover cloth 33, and the cover cloth 33 is sewn together with the sewing thread 9a when the upper sides of the outer fabric 3A and the lining 3B are sewn together.

Further, in order to show the base end side of the cover 2 by folding back the lower side part 32 of the handle plate 3 in a U shape, in the illustrated example, only the lower side part 32 of the dress material 3A extends downward. The extended portion 32a is not provided, and the extended portion 32a is folded back in a U-shape so as to cover the base end side portion of the cover 2.

In the figure, 5a indicates a hanging metal fitting, and 35 indicates a back plate edging material.

[0023]

As described above, the present invention can provide a school bag that can be used as a handbag by passing the hand through the handle hole 31 of the handle plate 3.

Further, according to the present invention, since the handle plate 3 is sewn to the back plate 1 with the sutures 6 over the entire width of the lower side of the handle plate 3, line joining is performed, and the connecting portion of the handle plate 3 is strong without damage. It is possible to provide various school bags.

Since the lower side of the handle plate 3 is sewn to the back plate 1 over a long distance, the handle plate 3 is like a conventional thin handle band even if it is held in the hand and walked. It is possible to provide a school bag that is comfortable to use and can be presented in a stable state without being twisted.

The width of the handle plate 3 of the present invention is equal to that of the back plate 1.
Since the width of the cover lid 2 is substantially the same as that of the cover lid 2, a sense of unity with the back plate 1 and the cover lid 2 can be expressed, a novel design can be expressed, and a school bag with a good appearance can be provided.
