Abstract

PROBLEM TO BE SOLVED: To provide a new pocket device for knapsack, bag and the like, which is convenient for elementary and junior high school students who insert long things such as a recorder, etc., thereinto in such a manner as to raise them for carrying them. SOLUTION: A pocket component piece, wherein right and left gusset parts are mounted on both of right and left side edges of a main plate part and which has a seam allowance part at the lower side edge of the main plate part and is manufactured of leather, a synthetic resin, a thick texture, etc., is mounted on a pocket fitting portion of a main body of the knapsack, the bag or the like. The boundary parts between the main plate part and the gusset parts are made mountain fold condition parts, lengthwise central line parts of the gusset parts are made valley-folded condition parts, and valley bottom parts of both side of the valley-folded condition parts are stitched to from the twofold gusset parts. The seam allowance part is seamed lapped in a reversed condition at the lower edge of the pocket fitting portion, and then the boundary part between the main plate part and the seam allowance part is folded to put the whole pocket part in such a condition as to be turned up. Thereby, the pocket part is put in such a condition to be positioned outside the pocket fitting portion, and the outer side edges of the gusset parts are seamed at the right and left parts of the pocket sitting portion in such a condition as the gusset parts are kept two-fold.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pocket device such as a school bag, a bag, etc., which is suitable for elementary and junior high school students to carry a so-called long object such as a recorder.

[0002]

2. Description of the Related Art A conventional pocket device of this kind has a relatively complicated structure, lacks smartness and is not necessarily in good appearance, and is used when a so-called long object such as a recorder is inserted and carried. There is a problem that a so-called long object such as a recorder falls off and is damaged, and the saliva attached by use in the recorder or the like is difficult to dry, and the saliva often stains the lower part of the pocket. .

[0003]

SUMMARY OF THE INVENTION The present invention provides a novel pocket device such as a school bag or bag obtained by conducting research and development for the purpose of solving the above problems.

[0004]

In order to achieve the above-mentioned object, a pocket device for a school bag, a bag or the like according to the present invention comprises a left and right gore portions on both left and right edges of a main plate portion and a seam portion on a lower edge. Leather, synthetic resin ground, thick woven fabric, etc. pocket component pieces are obtained by attaching them to pocket attachment points in the body of a school bag, bag, etc., and the boundary line between the main plate portion and the left and right gore portions is A pocket part having a left and right gore part which is folded in two by making a mountain fold state part and a vertical center line part of the left and right gore parts as a valley fold state part and further suturing both valley hem portions of the valley fold state part. And sewn the seam on the bottom side of the pocket mounting part with the inside out turned over, and then fold the border between the main plate and seam allowance to make the entire pocket part face up Pocket parts With the outer edges of the left and right gore parts sewn to the left and right sides of the pocket mounting part with the left and right gore parts folded in two, while being located outside the mounting point And

[0005] A hole for rain, brim, air or the like is formed in the boundary or low portion between the main plate portion 1 and the seam allowance portion.

[0006] Further, a rubber passage pipe is provided at the same position by sewing a horizontally long piece outside the upper portion of the main plate portion,
The rubber string is passed through the rubber pipe so that both ends of the rubber string are exposed, and both ends of the rubber string are sewn together in a tensioned state at the time of sewing the left and right gore parts to the pocket attachment points. It is made by wearing.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
That is, first, the left and right gore portions 2 and 3 are cut on both left and right edges of the main plate portion 1 and the pocket forming piece 5 having the seam portion 4 on the lower edge, and the main plate portion 1 and the seam portion are cut. A plurality of holes 10 for rain, brim, air, etc. are drilled in the boundary between the main plate 1 and the left and right gore portions 2 and 3 and the peaks are formed by bending the boundary between the main plate 1 and the left and right gore portions 2 and 3. The left and right gore portions 2 and 3 are formed into a valley-folded state portion 7 having a shape in which a bent portion is dented and a valley-folded portion is formed on both sides of the valley-folded state portion 7. The pocket parts 9 having the left and right gore portions 2 and 3 which are folded in two are formed by suturing the pocket parts 9.

Furthermore, a horizontally long small piece 11 is arranged outside the upper side of the main plate portion 1 and both upper and lower edges of the small piece 11 are
Sewn to the same place, a flat rubber through pipe 1
2, a flat rubber cord 13 is passed through the rubber passage tube 12 so that both ends of the rubber cord 13 are exposed.

Thereafter, the pocket parts 9 are attached to the side surface of the school bag body 15 in the following manner. That is, first, the seam allowance portion 4 is overturned on the lower side of the pocket mounting portion 17 on the outer surface of the side wall constituting portion 16 of the school bag body 15 and is sewn with the thread 18, and then the main plate portion 1 and the seam allowance portion 4 are sewn. The pocket part 9 is positioned outside the pocket mounting point 17 by bending the boundary part of the pocket part 9 so that the entire pocket part 9 is turned upside down, and the left and right sides of the pocket mounting point 17 are left. -The outer edges of the right and left gore parts 2, 3
Is sewn with the thread 18 in a state of being folded into two, thus forming a so-called collapsed pocket 19.

Further, when the left and right gore portions 2 and 3 are sewn to the above-mentioned pocket mounting portion 17, the both ends of the elastic cord 13 are sewn together in a reduced state and completed.

[0011]

Since the pocket device such as a school bag or a bag according to the present invention has the above-described structure, it is relatively simple and easy to obtain a smart, good-looking product with high product value. The pocket device for a school bag, a bag, or the like according to claim 2 is characterized in that holes for rain, saliva, air, and the like are formed in a boundary portion or a low portion between the main plate portion and the seam allowance portion. Therefore, when a so-called long object such as a recorder is inserted and carried, the saliva attached to the inner surface of the recorder or the like is easily dried due to internal and external communication through the drain hole, and the lower part of the pocket may be soiled. The school bag according to claim 3,
A pocket device for a bag or the like is provided with a rubber passage tube at the same location by sewing a horizontally long small piece outside the upper portion of the main plate portion. And the both ends of the rubber string are sewn together in a tensioned state at the time of sewing the left and right gore parts to the pocket attachment points, so that a so-called long object such as the recorder 20 is inserted into this. In the case of carrying it in, the contraction function of the rubber cord prevents the so-called middle part of a long object such as a recorder from being pressed down and falling off, and it is possible to completely avoid damage due to dropping out, for example, When a thing shorter than the depth of the pocket is stored, the opening becomes narrowed by the contraction function of the elastic cord, so that the stored thing does not fall out and does not play inside. It is those where there is the advantage, in which exhibits remarkable effects to fully achieve the intended purpose.
