Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a composite bag that can be used by combining or separating a main bag and a sub-bag, particularly a composite bag suitable for commuting to school.

[Conventional technology]

Conventionally, there are three types of bags used for commuting to school, etc., depending on how they are carried: backpack-type, hand-carried type, and shoulder-carry type.Furthermore, there are various types of bags with different sizes and shapes. Each of these bags was used alone, and could only accommodate less than a certain amount of luggage.

In addition, when these bags contained less baggage, the bag looked unsightly, so in that case, it was sometimes necessary to refill it with another small bag.

Particularly in the case of bags used by students, school children, etc., the amount of baggage they carry varies from day to day, so it is common practice to prepare multiple bags and use one according to the amount of luggage.

[The problem that the idea aims to solve]

In this way, students and school children can use it as a bag for commuting to school, depending on the amount of luggage they carry.
It is necessary to purchase and prepare two or three bags, which is an additional expense, is inconvenient to carry, and poses a risk of getting caught.

This invention was developed to solve the above problems.Although it is a single bag, it can be combined or separated depending on the amount of luggage and its purpose, and is a composite bag with excellent stability when carrying. The purpose is to provide a bug.

[Means to solve the problem]

This idea consists of a main bag, a sub-bag that is detachably connected to the front of the main bag,
A joint that connects these main bags and sub bags, a cover attached to the main bag so as to cover the upper and front surfaces of these bags when the sub bags are connected to the main bag or not, and an adjustable tightening member that connects the lower part of the main bag with the cover; a ring for carrying on the back attached to the upper center of the main bag; and a removable member that can be inserted into the ring and has engaging parts at both ends. a belt, two shoulder-carrying locking parts attached to both sides of the lower part of the main bag so as to be able to engage with the engaging parts, a carrying handle provided at the center of the upper surface of the cover, and the belt. two shoulder-carrying locking parts provided on both ends of the upper surface of the cover so as to be able to engage with the engaging parts of the sub-bag; a mounting member for holding long objects provided on the back surface of the cover; This is a composite bag that has a handle for carrying as a hand-carry provided in the upper center part, and two locking parts for carrying over the shoulder provided at both ends of the upper part of the sub-bag.

[Effect]

The composite bag of this invention uses a main bag and a sub-bag connected by a joint, covered with a cover, and connected by a tightening member, and the main bag and sub-bag can be used separately depending on the amount of cargo and the purpose. . When used in combination, the two can accommodate the maximum amount and function as a single bag for carrying. By separating the main bag and sub bag at the joint, each bag can store and carry a small amount of luggage as its own bag. In this way, when the materials are combined and when they are separated, it is possible to obtain three usage modes in which the amount to be transported differs.
In addition, by inserting the belt into the ring at the center of the upper part of the main bag and engaging the engaging parts at both ends with the locking parts on both sides of the lower part of the main bag, the bag can be carried like a backpack. In addition, the main bag and sub-bag can be used in a handheld manner by a handler, either combined or uncombined, and can also be used as a shoulder bag by engaging the engaging part of the belt with the shoulder locking part.

The installation lengths of the joints 27a and 27b that connect the main bag 1 and the sub bag 25 are fixed in advance according to the sizes of the main bag 1 and the sub bag 25.

Next, the manner in which the above-mentioned composite bag is used will be explained.

First, if you have a lot of luggage, as shown in Figure 2,
Use both main bag 1 and sub bag 25,
Main bag 1 and sub bag 25 where luggage is stored
After joining by joints 27a and 27b,
Main bag 1 and sub bag 2 with cover 17
At the same time, the tightening band 26 is wrapped around the outer periphery of the sub-bag 25 from the bottom 9 of the main bag 1, tightened, and connected by joints 24a and 24b. At this time, by adjusting the length of the tightening band 26 to which the joint 24b is attached in accordance with the amount of cargo, the sub-bag 25 is held with appropriate tension without the cover 17 sagging. In addition, by covering the main bag 1 and the sub bag 25 with the cover 17, it not only provides protection from the rain in case of rain, but also the main bag 1 and the sub bag 25 are integrated, which improves the appearance, and furthermore, the surface is flat with no protrusions. This improves safety.

The main bag 1 and the sub bag 25 can be carried in a combined state by using the central part of the band 18 on the upper surface of the cover 17 as a handbag.
Alternatively, the hook 8 of the belt 7 can be engaged with the ring 6 on the upper surface of the cover 17 to carry it over the shoulder, or the hook 8 at both ends of the belt 7 can be engaged with the ring 22 at the lower back of the main bag 1, and There are three ways to carry it on your back, by inserting it through the ring 43 on the back of the upper surface of the cover 17, and any method can be used.

In the case of the above-mentioned shoulder-carrying type or backpack-carrying type, the length of the belt 7 is adjusted to the optimum length using the adjustment section 38. In the case of the shoulder-carrying type, the main bag 1 can be carried in a well-proportioned state without sagging at the top, similar to the hand-carrying type. Furthermore, in the case of the backpack type, since the belt 7 is inserted through the ring 43, there is little swaying from side to side, providing excellent stability when carrying.

Next, if the amount of luggage to be carried is small and the main bag 1 is sufficient and the sub bag 25 is unnecessary, remove the sub bag 25, pack the baggage into the main bag 1 alone, and adjust the length of the tightening band 26 to be shorter. Then, by covering it with a cover 17, the main bag 1 can be used alone. In this case as well, it can be used in three ways: hand-held, shoulder-carried, and backpack-type.

Next, when there is even less cargo and the sub bag 25 is sufficient and the main bag 1 is not necessary, the sub bag 25 is used alone (not shown). When only the sub-bag 25 is used, it can be carried over the shoulder by connecting the belt 7 to the rings 31 on both sides, or carried by the hand using the hanging handles 33 extending upward from the front and back.
In addition, it is also possible to separate the main bag 1 and the sub bag 25 and use them simultaneously.

In addition, in the above embodiment, as sub-bag 25,
Although a smaller bag than the main bag 1 is shown, it may be of approximately the same size. Further, although the tightening band 26 is shown as the tightening member, it may be in the form of a cover, and the tightening member may be attached to the cover 17. Furthermore, the present invention can be applied not only to school bags but also to general bags.

[Effect of idea]

According to the present invention, the main bag and the sub-bag equipped with a cover are combined and separable by a joint, so they can be combined or divided depending on the amount of luggage and the purpose, and can be used as a single unit depending on the usage condition. It can be used in a well-balanced state, is easy to use, and has excellent appearance and safety. And since the belt can be passed through the ring and carried on the back, it has excellent stability when carried on the back. In addition, since a hanging handle and a shoulder locking part are provided, the main bag and the sub-bag can be used as a hand-carry type or a shoulder-carry type, respectively, with or without being combined. In this case, the locking parts for shoulder hanging are provided at both ends of the top surface of the cover, so
without causing any sagging at the top of the main bag.
It can be carried in a balanced manner. Furthermore, since a mounting member for long objects is provided on the back of the cover, long objects such as umbrellas can be carried in a stable manner.
