Description

[Technical Field]

[0001] The present invention relates to a school bag. Specifically, it relates to a school bag equipped with a secondary storage compartment at the front of the school bag body. In particular, it relates to a school bag equipped with a secondary storage compartment that can be opened wide to easily access items stored inside, even for younger children who are weak in strength. [Background technology]

[0002] A school bag generally comprises a school bag body with a main storage compartment that is open at the top, a lid that covers the upper opening of the main storage compartment, and left and right shoulder straps attached to the school bag body. The school bag body, lid, and left and right shoulder straps are usually made of leather or synthetic leather.

[0003] Many school bags also have a secondary storage compartment in front of the main storage compartment. The secondary storage compartment is, for example, a pocket located in front of the school bag body that opens and closes with a zipper.

[0004] Such a school bag having a secondary storage compartment is described, for example, in Patent Document 1 below.

[0005] Figure 1 of Patent Document 1 discloses a school bag equipped with a main storage compartment 2 (corresponding to the main storage section) and a front pocket 4 (corresponding to the secondary storage section) that is provided in front of the main storage compartment 2 and opens and closes with an opening and closing zipper. In the example shown in this figure, a secondary storage compartment 3 (vertically long storage compartment) that is open at the top is provided between the main storage compartment 2 and the front pocket 4 (corresponding to the secondary storage section). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3217756 (Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the conventional auxiliary storage section (front pocket 4) disclosed in Patent Document 1, even if the opening and closing fastener is opened, the top opening of the auxiliary storage section cannot be opened wide. This makes it difficult to reach inside the pocket. In particular, for younger children who have weak strength, opening the opening and closing fastener and then further opening the top opening to put items into the auxiliary storage section is more difficult than adults might imagine. In addition, it was difficult to see inside the pocket from the outside, which sometimes required users to feel around to remove items stored inside the pocket, making it very inconvenient to use.

[0008] The present invention has been made with the above points in mind, and relates to a school bag with a secondary storage compartment whose opening can be opened wide, particularly to a school bag with a secondary storage compartment whose opening can be opened wide to easily put things in and take them out, even for younger children who are weak in strength. [Means for solving the problem]

[0009] In order to solve the above problems, a school bag is provided which comprises a main storage section and a secondary storage section located in front of the main storage section, the secondary storage section comprising a secondary storage section body which opens towards the front, a front lid which extends from the lower edge of the secondary storage section body so as to cover the front opening of the secondary storage section body, and an opening and closing fastener which joins the front lid to the secondary storage section body so as to be openable and closable, the lower end of the opening and closing fastener reaching the underside of the secondary storage section.

[0010] In this backpack, the bottom end of the zipper reaches the underside of the secondary storage compartment, so the opening of the secondary storage compartment can be opened wide by opening the zipper. In other words, when the zipper is fully open, the front lid can easily tilt forward.

[0011] The lower edge of the auxiliary storage body has a lower cover piece formed smaller than the left-right width of the auxiliary storage body and whose tip is continuous with the lower part of the front lid, and left and right end edges located on both sides of this lower cover piece, and the lower end of the opening and closing zipper reaches the left and right end edges, so that the school bag can be made.

[0012] This backpack has a bottom cover that reinforces the lower part of the secondary storage compartment. The left and right ends of the bottom cover also function as fasteners.

[0013] The backpack may also have left and right flexible connecting members inside the auxiliary storage compartment that connect the auxiliary storage compartment main body and the front lid, and a partition member that is installed between the left and right flexible connecting members. Items are usually stored between the left and right flexible connecting members.

[0014] This backpack uses a flexible connecting member to regulate the degree of inclination of the front cover, and the partition member allows items such as printed materials to be stored in an organized manner, making it easier to take out the items stored inside.

[0015] The backpack may also be one in which the lower end of the flexible connecting member reaches the inner bottom surface of the main body of the sub-storage section.

[0016] This school bag is less likely to lose relatively small items (small items) even when placed in the secondary storage compartment.

[0017] The partition member may be a bag-like bag that can be opened upward.

[0018] This school bag can store relatively small items (small items) in the partition member, which reduces the possibility of losing the small items.

[0019] The partition member may be a bag-shaped bag that can be opened upwards and is configured to be openable by means of an edge fastener provided on the upper edge, and may also be used as a school bag.

[0020] This school bag allows you to store small items in the partition member and close the zipper, making it almost impossible to lose small items. [Effects of the Invention]

[0021] The present invention provides a school bag with a secondary storage compartment whose opening can be opened wide, making it easy for even younger children with weaker strength to take things in and out of the compartment. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0023] The following describes an example of a school bag with reference to the drawings. The school bag has a main storage compartment and a secondary storage compartment, and the secondary storage compartment has a secondary storage compartment body, a front lid, and an opening and closing zipper. For ease of explanation, the school bags shown in the drawings are shown with the lid wide open and hanging down toward the wearer (schoolchild) so that the main storage compartment and other parts can be easily seen. The following description will be given by way of example with reference to an embodiment, but the present invention and its components are not limited to the following description.

[0024] 1. Main storage area The main storage section 1 is a storage section provided in the school bag R, and is a box-shaped storage space that opens upward. In the main storage section 1, items such as textbooks and pencil cases are stored.

[0025] In this embodiment, the height of the main storage section 1 is approximately 29 cm, and the width is approximately 24 cm. Recently, the main storage section 1 has often been sized (height x width) to fit an A4 clear file.

[0026] 2. Secondary storage area The sub-storage section 2 is provided in front of the main storage section 1. Here, "front" refers to the direction in which the back of the person wearing the school bag faces (the front side of the school bag).

[0027] In this embodiment, the width of the auxiliary storage section 2 is approximately equal to the width of the main storage section 1. As shown in Fig. 1 and other figures, the auxiliary storage section 2 in this embodiment comprises an auxiliary storage section main body 21, a front lid 26, and an opening / closing zipper 27. In this embodiment, the upper left and right sides of the auxiliary storage section 2 (the upper left and right sides of the front lid 26) form gentle curves when viewed from the front. First, the auxiliary storage section main body 21 will be described as an example.

[0028] [Sub-storage unit body] As shown in Fig. 3, the auxiliary storage section main body 21 is open toward the front. Specifically, the auxiliary storage section main body 21 is made up of a wall surface 22 and edge portions (gusset portions) 23, 24, and 25 that extend forward from the outer periphery of the wall surface 22, and is open toward the front. In this embodiment, the edge portions are made up of an upper edge portion 23, left and right side edge portions 24, and a lower edge portion 25. The upper edge portion 23 and the left and right side edge portions 24 are gently continuous and form a gently curved shape when viewed from the front.

[0029] 2, the lower edge 25 is made up of a lower cover piece 251 and left and right edges 252. The lower cover piece 251 is formed to be smaller than the left and right width of the auxiliary storage body 21. In this embodiment, the left and right width of the auxiliary storage body 21 is approximately 24 cm, while the left and right width of the lower cover piece 251 is approximately 17.5 cm, and the left and right width of the lower cover piece 251 is approximately 73% of the left and right width of the auxiliary storage body 21. The left and right width of the lower cover piece 251 is preferably 60 to 80% of the left and right width of the auxiliary storage body 21, and more preferably 70 to 80% of the left and right width of the auxiliary storage body 21. In this embodiment, the lower cover piece 251 has a generally horizontally elongated rectangular shape.

[0030] Left and right edges 252 are located on both the left and right sides of the lower cover piece 251. As will be described later, the lower ends of the opening and closing zippers 27 reach these left and right edges 252.

[0031] [Front lid] The front cover 26 extends upward from the lower edge 25 of the auxiliary storage body 21 so as to cover the front opening of the auxiliary storage body 21. In this embodiment, the lower part of the front lid 26 is attached to the tip (front edge) of the lower cover piece 251 that constitutes the lower edge 25. Then, when the opening and closing zipper 27, which will be described later, is fully opened, the front lid 26 easily tilts forward.

[0032] [Opening and closing zipper] The opening and closing zipper 27 joins the front lid 26 to the sub-storage section main body 21 so that it can be opened and closed freely. The lower end of the opening and closing zipper 27 reaches the bottom surface of the sub-storage section 2. In this embodiment, a so-called two-way zipper, specifically a fastener with two sliders (also called a two-way fastener type) is used as the opening / closing zipper 27. As shown in FIG. 2, the lower ends (both ends) of the opening / closing zipper 27 reach the left and right edges 252 located on both sides of the lower cover piece 251. More specifically, the lower ends (both ends) of the opening / closing zipper 27 are configured to be close to the left and right edges of the lower cover piece 251. With this configuration, the lower end of the opening / closing zipper 27 reaches the underside of the auxiliary storage section 2. In the auxiliary storage section 2 configured in this manner, when the opening / closing zipper 27 is open (fully open), the front lid 26 is free to tilt forward, and in this embodiment, the front lid 26 is designed to naturally tilt forward.

[0033] Furthermore, in this embodiment, left and right flexible connecting members 28 and a partition member 29 are provided inside the sub-storage section 2. The left and right flexible connecting members 28 and the partition member 29 will be described below by way of example.

[0034] [Flexible connecting member] 3, the left and right flexible connecting members 28 connect the auxiliary storage unit main body 21 and the front cover 26. The left and right flexible connecting members 28 are located inside the auxiliary storage unit 2.

[0035] In this embodiment, the left and right flexible connecting members 28 connect the left and right inner sides of the auxiliary storage body 21 and the left and right inner sides of the front lid 26 inside the auxiliary storage section 2. The left and right flexible connecting members 28 are sized so that when the opening and closing fastener 27 is open, the front lid 26 is tilted forward at an angle of approximately 45 to 80 degrees with its lower edge as a fulcrum.

[0036] 4, the flexible connecting member 28 is configured so that its lower end generally reaches the inner bottom surface 20 of the auxiliary storage body 21. In detail, the distance between the lower end of the flexible connecting member 28 and the inner bottom surface 20 of the auxiliary storage body 21 is preferably 10 mm or less, more preferably 5 mm or less, and most preferably 0 mm (the lower end of the flexible connecting member 28 reaches the inner bottom surface 20 of the auxiliary storage body 21). The left and right flexible connecting members 28 may have a shape that narrows from top to bottom, such as a generally inverted triangle, a generally inverted trapezoid (the lower base is shorter than the upper base), or a generally fan shape.

[0037] There are no particular restrictions on the material of the left and right flexible connecting members 28, as long as it is strong enough to support the front cover 26 in its protruding state. For example, a synthetic fiber fabric can be used for the flexible connecting members 28. The flexible connecting members 28 are preferably made of a flexible material.

[0038] [Partition material] As shown in Fig. 3, the partition member 29 is provided so as to span the left and right flexible connecting members 28. In this embodiment, the partition member 29 is bag-shaped so as to be freely openable upward, as shown in Fig. 5, and is configured so that articles can be stored inside. In this embodiment, an edge fastener 291 is provided on the upper edge of the partition member 29. The partition member 29 does not have to be bag-shaped, and may be made of any fabric, for example. In this embodiment, the partition member 29 divides the interior of the sub-storage section 2 into front and rear sections.

[0039] Although the present invention has been illustrated and described above with reference to specific embodiments, the present invention is not limited to the above embodiments, and various changes and modifications can be made by those skilled in the art without departing from the scope of the claims attached to the application of this application.

[0040] For example, the inner bottom surface 20 of the auxiliary storage section 2 and the inner bottom portion including this can be made a light color tone. For example, the inner bottom surface 20 of the auxiliary storage section 2 and the inner bottom portion including this can be made a color tone with a Munsell color system brightness ranging from 5 to 10 (for example, a light orange color). This makes it easier to find small items even when they are placed in the auxiliary storage section 2. In the above embodiment, the wall surface 22, the left and right flexible connecting members 28, and the partition member 29 are made a color tone with a Munsell color system brightness ranging from 5 to 10 (a light orange color).

[0041] Furthermore, the main storage compartment 1 may be divided into a front and a back, or a belt may be attached to the inner wall on the wearer's side of the main storage compartment 1. By positioning heavy items closer to the wearer, the sense of stability when carrying the school bag increases, making it feel lighter to the wearer.

[0042] In addition, in this embodiment, a vertically long storage chamber 5 is provided between the main storage section 1 and the sub-storage section 2, but this is not limiting. For example, the vertically long storage chamber 5 does not have to be provided, or a vertically long openable pocket or the like may be provided instead of the vertically long storage chamber 5.
