Description

The present invention relates to bags, such as shoulder bags, handbags, wallets, school bags, etc., which are provided with a variable capacity storage section.

Conventionally, in bags, even if the bag is usually small in thickness, when storing thick documents or books, a bellows-shaped gusset is used, for example, as in the wallet storage section 50 of Patent Document 1. It is normal to expand the storage capacity and use it.

Patent No. 5431613

However, in this case, since the storage section is structured so that it can easily expand due to the gusset, there is a problem in that when a specific thin stored item is stored, this specific stored item is likely to fall out.

An object of the present invention is to solve the above-mentioned problems by providing a storage section with a variable capacity that does not normally have an unintentional increase in capacity, so that even if a large thickness of the stored object is stored, the stored object can be held down appropriately. To provide a bag that prevents stored items from falling off when attached.

A bag according to the present invention for achieving the above object is a bag having a variable capacity storage section on the side of the main body, the variable capacity storage section extending outward from the bottom of the main body. It has a sheet-like outer surface portion that extends and can be further folded upward with respect to the bottom portion, and sliding pieces that extend from both left and right sides of the outer surface portion and can be folded back inward, A sliding means is provided between the piece and the inner surface on the main body side, for connecting the sliding piece to the inner surface and sliding the sliding piece in the left-right direction with respect to the inner surface. It is characterized by:

Even if the bag according to the present invention is normally kept flat, when a thick item is stored, the bag expands according to the thickness, making it possible to store the item while holding it down.

FIG. 3 is a perspective view of the variable capacity storage section assembled and with a part of the outer surface section cut away.

The present invention will be explained in detail based on illustrated embodiments.

FIG. 1 is a perspective view of a shoulder bag 1 according to a first embodiment in which, for example, a thick book is stored in the variable capacity storage section and the lid is opened.

This shoulder bag 1 is manufactured by cutting a sheet-like leather material having a thickness of, for example, 1.5 mm into a predetermined shape and sewing it. The main body part 2 is divided into a plurality of parts and has storage parts 3a and 3b that can store items of normal thickness, and the side part has a variable capacity storage part that stores, for example, a book B. 4 is provided. Further, a lid part 5 extends from the back side of the main body part 2 and covers the open parts of the storage parts 3 and 4 from above, and shoulder straps 6 are attached to both sides of the main body part 2.

FIG. 2 is a perspective view of the variable capacity storage section in a flat, unfolded state, and dotted lines in the figure indicate internal fold lines. The variable capacity storage section 4 has a connecting section 4a made of leather extending from the bottom of the main body section 2, and an outer surface section 4b connected to the outside of the connecting section 4a. Further, rectangular sliding pieces 4c and 4c' extend on both left and right sides of the outer surface part 4b, and the sliding pieces 4c and 4c' have a folding tendency so that they can be folded back inward with respect to the outer surface part 4b. is attached.

A notch 4d is provided on the upper side of the outer surface portion 4b to make it easier to take out stored items, and a cutout 4d is provided at two upper portions of the sliding pieces 4c and 4c' along the left and right direction parallel to the connecting portion 4a. Slit-shaped elongated holes 4e and 4e' each having a diameter of 3 mm and a length of 20 mm are bored.

On the other hand, on the inner surface 4f provided on the main body 2 side, a pair of pseudo jewel-shaped locking tools are inserted into the long holes 4e and 4e' and are slidable relative to each other along the left and right longitudinal directions. 4g and 4g' are fixedly arranged corresponding to the elongated holes 4e and 4e'. The locking tools 4g, 4g' are made of metal or synthetic resin, and the locking tools 4g, 4g' are inserted into the long holes 4e, 4e' at the tip of the shaft portion 4h with a diameter of 2.5 mm and a length of about 4 mm. A disc-shaped stopper 4i with a diameter of about 8 mm is provided to prevent it from coming off.

When assembling the variable capacity storage section 4, as shown in FIG. 3, the outer surface section 4b is raised upward from the connecting section 4a to face the inner surface section 4f of the main body section 2, and the outer surface section 4b and the inner surface section 2b are In between, sliding pieces 4c and 4c' folded back inward from the outer surface portion 4b are interposed.

When the outer surface portion 4b is raised, the sliding pieces 4c and 4c' on both sides are folded back inwardly from the outer surface portion 4b by about 180 degrees. By inserting locking tools 4g and 4g' into long holes 4e and 4e' provided in sliding pieces 4c and 4c' as sliding means, connecting part 4a, outer surface part 4b, inner surface part 4f, and A variable capacity storage section 4 is obtained which is surrounded by the movable pieces 4c and 4c' and whose upper part is open.

Furthermore, female hooks 7 are attached to, for example, two locations on the outside of the lid portion 5, and can be coupled to male hooks 8 provided on the surface of the outer surface portion 4b. If the length of the lid 5 is allowed to be long enough, the lid 5 can be used even if the thickness of the stored items changes.

When nothing is stored in the variable capacity storage section 4, due to the folding tendency of the sliding pieces 4c and 4c', the outer surface portion 4b is in a flat state in close contact with the inner surface portion 4f, and the locking tools 4g and 4g' are located at corresponding positions along the longitudinal direction of the elongated holes 4e and 4e'.

Here, as shown in FIG. 1, when a thick book is stored in the variable capacity storage section 4, for example, the sliding pieces 4c and 4c' are locked through the long holes 4e and 4e' in accordance with the thickness of the book. It slides along the tools 4g and 4g' and is pulled out to both sides, and the gap between the outer surface portion 4b and the main body portion 2 is widened to provide a gap sufficient to accommodate a thick book. At this time, as the thickness of the storage section 4 increases, the locking tools 4g and 4g' slide relatively in the left and right directions within the elongated holes 4e and 4e', and the sliding pieces 4c and 4c are moved by the stopper 4i. ' is drawn toward the main body 2, so the gap between the outer surface 4b and the main body 2 does not expand more than necessary. It should be noted that since the locking tools 4g and 4g' are slidable within the length range of the elongated holes 4e and 4e', the capacity of the variable capacity storage portion 4 is variable within this sliding range.

As described above, in the shoulder bag 1 according to the first embodiment, the plurality of conventional storage sections 3a and 3b normally store items such as documents and accessories that need to be carried, but the capacity variable storage section Since the section 4 can store books, documents, etc. that are too thick to be stored in the storage sections 3a and 3b, the variable capacity storage section 4 can be adjusted to correspond to the size of the article to be stored, so that its thickness, i.e., the content capacity, can be adjusted accordingly. Can be changed.

Therefore, the shoulder bag 1 can be used in a smaller size due to the folding tendency of the sliding pieces 4c, 4c' against the outer surface 2a, but the shoulder bag 1 can be used in a smaller size due to the folding tendency of the sliding pieces 4c, 4c' against the outer surface 2a. By adjusting the lateral positions of the pieces 4c and 4c' within the sliding range, it is possible to store thick items in the variable capacity storage section 4.

In addition, in order to prevent the space between the outer surface part 4b and the inner surface part 4f of the variable capacity storage part 4 from expanding more than necessary during use, the ends of the sliding pieces 4c and 4c' are connected to each other as shown in FIG. It is also suitable to connect the parts with a rubber band 9 or the like. Since the sliding pieces 4c and 4c' are attracted to each other by the rubber band 9, the gap between the outer surface portion 4b and the inner surface portion 4f is always urged to narrow.

FIG. 5 is a perspective view of the variable capacity storage section 4' of the shoulder bag 1' of the second embodiment in an expanded state before being assembled, and the same reference numerals as in the first embodiment indicate the same members.

Approximately triangular sliding pieces 4j, 4j' with narrow tips extend on both left and right sides of the outer surface portion 4b. As the sliding means, the tips of the sliding pieces 4j, 4j' are, for example, belt parts 4k, 4k' with a width of 25 mm, and locking pieces 4l, 4l' with a width of about 40 mm are attached to the leading ends of the belt parts 4k, 4k', respectively. . In addition, two slit holes 4m and 4m' each having a length of 30 mm, for example, are arranged in two places on the inner surface part 4f in the vertical direction at an interval of about 10 mm, corresponding to the belt parts 4k and 4k'. Notched.

As shown in FIG. 6, the belt parts 4k, 4k' and the locking pieces 4l, 4l' are inserted into two slit holes 4m each, and are extended from the other slit hole 4m' to the outside of the inner surface 4f. It's being pulled out and pulled out. Since the locking pieces 4l and 4l' are formed wider than the length of the slit holes 4m and 4m', even if the belt parts 4k and 4k' slide relative to the slit holes 4m and 4m', the length of the slit holes 4m and 4m' , 4m'.

In the second embodiment, since the variable capacity storage section 4' having such a sliding means is provided, similarly to the first embodiment, the outer surface part can be adjusted depending on the position of the sliding pieces 4j, 4j' in the left and right direction. Since the gap between the inner surface 4b and the inner surface 4f can be adjusted, thick objects can be stored.

In the second embodiment as well, it is also preferable to connect the sliding pieces 4j, 4j' with the rubber band 9. In addition, when using the rubber band 9 in Example 2, the locking pieces 4l and 4l' may be omitted and the ends of the belt parts 4k and 4k' may be directly connected to each other by the rubber band 9. .

Although leather is used as the material in the embodiment, there is no problem in using a synthetic resin sheet. Further, in the embodiment, two sets of sliding means were provided between the sliding pieces 4c, 4c' and 4j, 4j' and the inner surface 4f, but one set of sliding means was provided between the sliding pieces 4c, 4c. and 4j, 4j', and the other sliding pieces 4c, 4c' and 4j, 4j' are fixed between the outer surface part 4b and the inner surface part 4f without having a sliding function. You can.

In addition to the hooks 7 and 8 used in the embodiment, a locking band, a hook-and-loop fastener, a magnetic hook, or the like may be used to lock the lid portion 5 to the outer surface portion 4b of the variable capacity storage portion 4.

Furthermore, in the embodiment, a shoulder bag was explained, but it can also be used to store books, laptops, tablets, etc. in bags such as school bags and handbags, or to store bills, smartphones, etc. in a wallet. The variable capacity storage section 4 of the present invention can be applied. Further, a dedicated lid portion may be provided for the variable capacity storage portions 4, 4'.

Moreover, since the dimensions in the description are merely examples, there is no need to be concerned with these dimensions in any way.
