Description

  The present invention relates to a shoulder bag such as a tote bag that can reduce the burden on the shoulder by dispersing the weight of the bag on the shoulder when the bag is hung on the shoulder.

In recent years, bags that are easy to use and are casual, such as tote bags, have been used. Such a bag has the advantage that it is easy to put in and take out an object because the door is wide open, and a large amount can be stored. For this reason, a lot of things are often used.
However, adding a large amount of objects increases the weight of the entire bag, increasing the burden on the shoulder. By the way, in order to reduce the weight of such a bag, as shown in Patent Document 1 below, a bag has been developed that reduces a load applied to a person when carrying the bag.

JP2007-181612

  However, the idea disclosed in Patent Document 1 relates to a bag of a type such as a so-called attache case, and the burden on the shoulder is reduced by distributing the weight applied to the handle using a shoulder strap. I am trying. In other words, you need both a handle and a shoulder strap. For this reason, it cannot be used for shoulder-type bags such as tote bags. An object of the present invention is to provide a bag that reduces the burden on the shoulder due to the weight of the bag with a very simple structure.

  Therefore, as a result of earnest and research conducted by the inventor in order to solve the above-mentioned problems, the present inventor is provided so as to face the bag-shaped bag body portion having the upper portion as the opening portion and the opening portion. The handle comprises a pair of handles, and the handle has a non-stretchable portion and a stretchable portion of a predetermined length formed on at least a part of the handle, and the stretchable portion has an elastic body inside. The above-mentioned problem has been solved by providing a shoulder bag characterized in that the outside is integrally formed as a covering portion.

  Moreover, the said subject was solved by making Claim 2 into the shoulder bag characterized by the said expansion-contraction part being formed in predetermined length from the both ends of the said handle in Claim 1. According to a third aspect of the present invention, the above-described problem is solved by using the shoulder bag according to the first aspect, wherein the handles are all formed as stretchable parts. The above-mentioned problem has been solved by forming a shoulder bag according to claim 4, wherein the elastic body is a belt-like rubber plate in any one of claims 1, 2, or 3.

In the invention of claim 1, in a shoulder bag such as a tote bag, the non-expandable part and the elastic part of the handle are integrally formed continuously, the elastic part includes an elastic body inside, and the outside is bellows-like Since the elastic body of the stretchable part and the covering part are integrated,
When a baggage is put in a shoulder bag and walked over the shoulder, the stretchable part expands and contracts to reduce the load on the shoulder. Also, the stretchable part expands and contracts according to the walking rhythm, but when the stretchable part shrinks, the load on the shoulder is reduced, and when it stretches, the weight of the bag is applied to the shoulder again. An effect is obtained.

  In addition, the inner elastic body and the outer covering portion are fixed and integrally formed in the stretchable part, so that the elastic body can be stretched and stretched within the length range of the covering portion. Since the burden on the elastic body when a heavy load is put is reduced and elastic fatigue is less likely to occur, there is an advantage that the stretchable part lasts longer. In addition, since the non-stretchable part and the stretchable part are formed integrally and continuously, there is an advantage that the material of the entire handle can be made the same and the structure can be extremely simplified.

  In the invention of claim 2, since the expansion / contraction part is formed at both ends of the handle, the expansion / contraction part is formed continuously from the coupling part where the bag main body part and the handle are combined. The weight is easily transmitted to the expansion / contraction part, and the load on the shoulder can be surely reduced. According to the invention of claim 3, since the entire handle is formed as an expansion / contraction part, the load on the shoulder is stably reduced, and the degree of expansion / contraction increases, so even a relatively heavy load can be applied to the shoulder. The load is reduced. Moreover, a larger massage effect can be obtained. The invention according to claim 4 can realize appropriate expansion and contraction by using an elastic body as a belt-like rubber plate.

It is an enlarged view of the state where the part has shrunk.

  A first embodiment of the present invention will be described with reference to the drawings. The shoulder bag according to the present invention comprises a bag body 3 having an upper opening and a pair of handles A and A provided so as to face each other at the opening 31, the handle A being a non-stretchable part 1. And a stretchable part 2 having a predetermined length formed at least in part (see FIGS. 1A and 1B). Specifically, the extendable parts 2 and 2 are provided with a predetermined length from both ends of the handle A starting from the connecting parts 4 and 4 of the bag body 3 and the handle A. Here, the non-stretchable portion 1 means a portion other than the stretchable portions 2 and 2 of the handle A.

  The expansion / contraction part 2 is comprised by the elastic body 21 and the exterior coating | coated part 22 (FIG. 1 (C) (D)). FIG. 1C shows a state where the stretchable part 2 is in a normal state. Here, let the length of the elastic body 21 when the expansion-contraction part 2 is in a normal state be a normal state length H. At this time, the covering portion 22 covering the elastic body 21 has a bellows shape. Next, FIG. 1 (D) shows a case where the stretchable part 2 is extended. Here, let the length of the elastic body 21 when the said expansion-contraction part 2 is extended be the maximum length Hmax. At this time, the covering portion 22 is also elongated and is not in a bellows shape.

The stretchable part 2 will be described more specifically. First, the dough 5 for the handle is opened, and both ends of the elastic body 21 having the normal state length H are applied with a force F at positions where the stretchable portions 2 of the handle A are formed (here, both ends of the handle A). Pull and extend to the maximum length Hmax, and handle fabric 5
It fixes to the center of the width direction (FIG. 2A). In this state, both ends of the handle fabric 5 are folded so as to overlap at the center in the width direction (FIG. 2B), and the center portion and both ends overlapped with each other are sewn in the vertical direction by a sewing machine or the like. The fabric 5 for the handle and the elastic body 21 are fixed (FIGS. 2C, 2D, and 2E). As can be seen from FIGS. 2D and 2E, the handle fabric 5 and the elastic body 21 are fixed in close contact with each other. Here, the portion of the handle fabric 5 that adheres to the elastic body 21 is the covering portion 22.

Since the stretchable portion 2 is formed in this way, the length of the handle fabric 5 at the covering portion 22 becomes the maximum length Hmax obtained by extending the elastic body 21. Since the elastic body 21 has a normal state length H in a normal state, the length of the handle fabric 5 in the covering portion 22 is longer than the normal state length H of the elastic body 21 by Hmax−H. Since the elastic body 21 is fixed in the maximum state length Hmax, in the normal state where nothing is put, the length of the covering portion 22 is also the normal state length H, and the excess fabric portion is shrunk. It becomes bellows (FIGS. 3A and 3B). In addition, since the elastic body 21 is fixed to the handle cloth 5 in an extended state, the maximum length of the expansion / contraction part 2 does not exceed the maximum length Hmax. Elastic fatigue of the elastic body 21 when the weight is too heavy can be suppressed.

  The stretchable part 2 and the non-stretchable part 1 are formed integrally and continuously, but nothing is included in the non-stretchable part 1. However, a core may be inserted to increase the strength of the handle A. In addition, a belt-like rubber plate 211 is used as the elastic body 21 included in the stretchable part 2. Here, the belt-like rubber plate 211 may be made of cloth or synthetic resin.

As a second embodiment of the present invention, there is one that uses the entire handle A as the expansion / contraction section 2. In this case, the maximum length Hmax obtained by extending the normal state length H of the elastic body 21 is set as the length of the handle A, and the elastic body 21 and the handle fabric 5 are fixed to each other in the same manner as described above. A is formed. As a result, in the normal state, the entire handle A becomes the extendable part 2 (FIGS. 5A and 5B). When the entire handle A is an expansion / contraction part, the expansion / contraction width becomes larger (FIG. 5A). The stretchable part 2 may be formed in any number as long as it is 1 or more, but it is preferably formed so as to be symmetric with respect to the U-shaped part 11 on the shoulder. For example, when only one stretchable part 2 is formed, it is preferable to form it in the U-shaped part 11 so as to be symmetric. However, it is preferably symmetrical, but may be asymmetrical.

FIG. 5 (A) is a state diagram of walking with a bag loaded on the shoulder bag according to the present invention on the shoulder. At this time, according to the walking rhythm of the shoulder bag, the expansion / contraction part 2 of the handle A expands and contracts vertically. More specifically, the stretchable part 2 is stretched by an extension length α in a state where a bag item is put on the shoulder and becomes a start state length H + α (FIG. 5B). The elastic part 2 expands to the maximum length Hmax by the reaction that has moved (FIG. 5C).
Since 1 is included, it shrinks after expansion. When the length of the reduced portion at the time of the reduction is the reduced portion length β, it expands and contracts to the maximum reduced length H−β (FIG. 5D). That is, while walking with the bag on the shoulder, the length of the stretchable portion 2 starts from the state of H + α, and continues to stretch in the order of H + α → Hmax → H → H−β → H → Hmax.

At this time, assuming that the weight felt on the shoulder is the starting state weight P when the length of the expansion / contraction part 2 is H + α, the maximum weight Pdown when the length is Hmax, and the minimum weight Pup when the length is H−β. Become. here,
The relationship of P is Pup <P <Pdown. That is, the maximum weight Pdown felt on the shoulder when the bag is lowered is the largest, and the minimum weight Pup felt when the bag is raised is the smallest. Therefore, the weight felt on the shoulder changes according to the expansion and contraction of the expansion / contraction part 2, and since a constant weight is not continuously applied to the shoulder, the burden on the shoulder can be reduced.

In addition, the shoulder feels a certain stimulus by the weight felt on the shoulder depending on the expansion / contraction of the expansion / contraction part 2. This brings about the same effect as a moderate massage on the shoulder, and the burden on the shoulder when moving a heavy load on the shoulder is reduced.

  Lastly, the bag may have gussets on the side and bottom surfaces of the bag body 3 or may not have gussets. The shape of the bag body 3 may be either square or circular. Further, the upper opening 31 may be closed with a fastener, a button, an upper lid or the like, or may remain open. Furthermore, the case where the pocket is provided in any or all of the front surface, the back surface, and the side surface of the bag body 3 is also included.
