Description

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, since a school bag has been used for a long period of 6 years, various measures for improving durability have been made since ancient times, and recently, it has not been damaged even if it is used for 6 years under normal use. There is a strong demand for durability.

However, a robustly manufactured school bag is also
There is a problem in that there are places that are easily damaged locally. In addition, it has been attempted to take out such a fragile place from the past example and reinforce the part with a metal fitting, but if the metal fitting is used easily, durability can be satisfied, but stored items can be stored. If a large number of heavy satchels are dropped onto the legs or the like, the reinforcing metal fittings may be injured, and the utmost caution is required for the reinforcement.

Further, the school bag is made mainly of natural leather or leather made to resemble natural, and these leathers have some elasticity and bendability. If the portion is reinforced with a hard and strong reinforcing material, there is a problem that a portion adjacent to the reinforcing portion is more likely to be damaged or causes abrasion. Specifically, if the sewn portion is sandwiched by U-shaped metal fittings for reinforcement, the suture can be prevented from being cut, but the phenomenon that the leather material at the end of the metal fitting is rather likely to be damaged occurs. In addition, the gusset surface of the school bag (displayed as the gusset plate portions 11b and 11c in the present application)
For the purpose of improving the self-maintaining property of, when a metal fitting or a core material of a hard resin plate is interposed in the gusset board portion, the outer leather material having the core material is easily worn, and the gusset board portion The core material may be exposed at the corners of the bottom surface for several years.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention has been made in view of the above problems and demands, and an object of the present invention is to provide a school bag which can improve durability without using hard metal fittings. Is.

The sewn portions at the upper end portions of the front plates 1b and 11c and the front plate 12 are covered and hidden so that the appearance is improved.

Next, in the invention of claim 2, the bottom surface portion 11a
And a pair of gullet plates 11b and 11c, which are continuously provided on both sides of the bottom surface part 11a in a right-angled bent shape, form a body part 11, and a front plate 12 is provided on one end side of the body part 11 and the other end side thereof. In a school bag having a back plate 13 attached thereto to form a main body 10 having an open upper portion, the body portion 11 is composed of a substrate 31 and a front material 32 attached to the outer surface of the substrate 31, and both gusset plates are provided. Part 11
Between the base plate 31 of b and 11c and the surface material 32, the upper end side of the gable plate parts 11b and 11c is located at the upper end side.
It is slightly narrower than the width of 1c, and has a substantially T-shape whose lower end side is narrowed toward the center side, and is provided with a relatively hard reinforcing plate 33 capable of sewing with a sewing machine, and further below the reinforcing plate 33. A cushion strip 34 made of foamed synthetic resin or the like is vertically interposed between the substrate 31 and the front fabric 32 at the center of both gland plate portions 11b and 11c, and the lower end side of the cushion strip 34 is Between the base plate 31 and the front cloth 32, the bottom face part 11a side is formed so as to enter, and both of the gusset plate parts 11b and 11c.
A series of reinforcing band materials 21 are provided on the outer surfaces of the upper ends of the front plate 12 and the front plate 12.
The reinforcing band material 21 is sewn to the main body 10 with the sewing thread 21a that also penetrates the reinforcing plate 33, and the edging material 22 is formed on the lower side of the reinforcing band material 21 to sandwich the edge thereof in a substantially U shape. Attaching, and further, on the upper side of the reinforcing band material 21, a hemging material 23 for sandwiching the upper ends of both the gullet boards 11b and 11c and the front plate 12 together in a substantially U shape is sewn on the sewing thread 23a.
It is a technical means characterized by being attached by suturing with.

Therefore, in addition to the effect of the first aspect, the school bag of the present invention has the upper end on the upper part of both the gore board parts 11b and 11c between the substrate 31 and the surface material 32 of the gore board parts 11b and 11c. The side is slightly narrower than the width of the gusset plates 11b and 11c, and the lower end side is a substantially T-shape with a width narrowing toward the center side, and a relatively hard reinforcing plate 33 capable of sewing with a sewing machine is interposed. Therefore, the upper portions of the gusset board portions 11b and 11c have the reinforcing plates 33 and 33, respectively.

Since it is arranged so as to cross the upper end connecting portion between the front plate 12 and b and 11c, it exhibits an effect of efficiently reinforcing this portion.

[0013]

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the figure, 10 is the body of the school bag, and this body 10 has a bottom portion 11a and a body portion 11 that is formed by a pair of gusset plates 11b and 11c connected to both sides of the bottom portion 11a at right angles. , The front plate 12 is provided on one end side of the body portion 11.
It is the same as the conventional school bag in that the back plate 13 is attached to the other end side to form a box shape with an open top.
Although not clearly shown in the figure, the front plate 12
A seam allowance portion that is bent at a right angle is continuously provided on both sides and the bottom side of the base, and the bottom surface part 11a and both side plate parts 11 are provided at the seam allowance part.
It is the same as the conventional one in that one end edge portion with b and 11c is sewn. Further, an outer right angled seam allowance is bent continuously on the other side of the bottom surface part 11a and both the gore board parts 11b and 11c, and this seam allowance is sewn to the edge of the back plate 13. Is the same as before.

And, according to the present invention, both of the above-mentioned gusset plates 11b,
A series of reinforcing band fabrics 21 are provided on the outer surface side of the upper end portions of 11c and the front plate 12, and a edging fabric 22 is attached to the lower side of the reinforcing band fabrics 21 so as to sandwich its edge portion in a substantially U shape. That is, one piece of the reinforcing band material 21 is used for one side of the goose board part 1.
It is adapted to be bent from 1b along the front plate 12 and further bent to reach the other goreboard part 11c.

Generally, the reinforcing band material 21 and the edging material 22 are the same as the material forming the main body 10 of the school bag, such as natural leather or synthetic leather (these are simply referred to as leather). Since these leathers are somewhat stretchable, a straight belt-shaped member having a predetermined width is prepared, and the upper side of the upper end portions of both the gore plate portions 11b and 11c and the front plate 12 is substantially the upper side. It may be arranged so that they are aligned with each other, but if there is insufficient stretchability and it is not possible to deform the upper side of the gore board parts 11b and 11c so that the upper side of the linear reinforcing band material 21 fits, a curved shape is prepared beforehand. It is advisable to prepare a reinforced band material 21 that has been modeled.

Since the edging material 22 has a small width, it can be sufficiently deformed even if it has a linear band shape. Further, one or both of the reinforcing band material 21 and the edging material 22 may be intentionally made of different materials or different in color tone so as to have a design change. If you use a tape with a phosphorescent agent, you can tell the driver of a night car that school children are walking.
It can be emphasized and recognized. The reinforcing band material 21 and the edging material 22 are attached to the main body 10 by gluing, sewing or both.

Further, according to the present invention, an edging material 23 is attached to the upper side of the reinforcing band material 21 so as to sandwich the upper ends of both the gusset plates 11b and 11c and the front plate 12 together in a substantially U shape. This edging material 23 was also attached to the conventional school bag, but in the past, separate pieces were attached to the goreboard portions 11b and 11c and the front plate 12, but in the present invention, both goreboard portions 11b and 11b, A series of edging material 23 is provided across 11c and the front plate 12.

Next, the invention of claim 2 is that the bottom surface portion 11a
And a pair of gullet plates 11b and 11c, which are continuously provided on both sides of the bottom surface part 11a in a right-angled bent shape, form a body part 11, and a front plate 12 is provided on one end side of the body part 11 and the other end side thereof. In a school bag having a back plate 13 attached thereto to form a main body 10 having an open upper portion, the body portion 11 is composed of a substrate 31 and a front material 32 attached to the outer surface of the substrate 31, and both gusset plates are provided. Part 11
Between the base plate 31 of b and 11c and the surface material 32, the upper end side of the gable plate parts 11b and 11c is located at the upper end side.
It is slightly narrower than the width of 1c, and has a substantially T-shape whose lower end side is narrowed toward the center side, and is provided with a relatively hard reinforcing plate 33 capable of sewing with a sewing machine, and further below the reinforcing plate 33. A cushion strip 34 made of foamed synthetic resin or the like is vertically interposed between the substrate 31 and the front fabric 32 at the center of both gland plate portions 11b and 11c, and the lower end side of the cushion strip 34 is It is arranged between the substrate 31 and the surface material 32 so as to also enter the bottom surface portion 11a side.

The body portion 11 is composed of the substrate 31 and the surface material 32 attached to the outer surface of the substrate 31 by a conventional conventional means, and a backing material is attached to the inner surface of the substrate 31. Is also good. Then, both side plate parts 11b, 1
It has been tried to interpose a reinforcing plate 33 on the upper portion of 1c, but since a rubber plate has been used conventionally, sufficient self-maintaining property was not obtained. Therefore, in the present invention, a relatively hard sewing machine is used on the assumption that the sewing machine can be sewn. The recent sewing machine suturing device is capable of penetrating the sewing machine needle even if it is considerably hard, so that there is no problem in suturing. Therefore, a synthetic resin plate material having a thickness of about 1 to 3 mm has no problem in suturing. Then, such a synthetic resin plate material may be used. It should be noted that the weight reduction and the gore board 11
In order to secure the rigidity of b and 11c to some extent, the reinforcing plate 33 is provided only on the upper portions of the gore plate portions 11b and 11c.

The substrate 31 is provided below the reinforcing plate 33.
A cushion band member 34 made of foamed synthetic resin or the like is vertically interposed between the front cloth 32 and the front cloth 32, and the lower end side of the cushion band member 34 is the substrate 3
It is arranged between 1 and the surface material 32 so as to enter the side of the bottom surface portion 11a. That is, the cushion strip 34 is formed from the lower portion of the reinforcing plate 33 to the bottom portion 11
It is designed so that it can be inserted up to a.

The portion where the cushion band member 34 is interposed bulges outward by about that amount. Therefore, both side panel parts 11b, 11c or both side panel parts 11b, 1
When the corner portion between 1c and the bottom surface portion 11a contacts another object, the bulged portion first contacts another object.
The bulging portion is rich in flexibility by interposing the cushion band member 34, and is easily deformed to prevent abrasion.

Further, a series of reinforcing band materials 21 are provided on the outer surfaces of the upper ends of both the gusset plates 11b and 11c and the front plate 12, and a sewing thread which penetrates the reinforcing band material 21 also through the reinforcing plate 33. 21a is sewn to the main body 10 and the reinforcing band material 21
On the lower side, the edging material 2 whose edge is sandwiched in a substantially U shape
2 is attached. Even if it is a reinforcing material, if it is too hard, the fabric constituting the satchel is a flexible material and also has some elasticity, so the integrity is impaired and, as mentioned above, the adjacent parts tend to be easily damaged. Occurs. Therefore, in order to reduce this defect as much as possible, the reinforcing plate 33 is also sewn together so as to be integrated more reliably.

Then, on the upper side of the reinforcing belt material 21,
The upper ends of both the gusset plates 11b and 11c and the front plate 12 are both substantially U-shaped.
The edging material 23 sandwiched in a letter shape is sewn and attached with the sewing thread 23a, which is the same as the configuration of claim 1.

[0024]

According to the first and second aspects of the present invention, it is said that the appearance is not good, and the upper end portions of the sutures between the gluteal plate portions 11b and 11c and the front plate 12 which are most easily broken are sewn. Reinforce with the reinforcing band material 21 and the edging materials 22 and 23,
In addition, it is possible to provide a school bag that can be covered with the edging material 23 and can be reinforced without using metal fittings.

In particular, according to the second aspect of the present invention, since the relatively hard reinforcing plate 33 and the cushion band member 34 made of foamed synthetic resin are interposed in each place, the self-maintaining property is improved, but the abrasion loss is prevented. It is possible to provide a school bag that can be reasonably reinforced.

In the present invention, the reinforcing plate 33 is attached to the sewing thread 2
Since it is sewn together with the main body 10 at 1a, it is possible to provide a school bag that can be surely integrated with the surface material 32 and can prevent the surface material from being easily damaged even if a hard reinforcing plate 33 is interposed. It is a thing. In the present invention, the sewing thread 23
Since the a and 21a are arranged so as to traverse the upper end connecting portion between the two gore board parts 11b and 11c and the front plate 12, it is possible to provide a school bag which can be strongly reinforced by the sewing threads 23a and 21a.
