It is a figure which shows one Embodiment of the strap of this invention. It is a front view which shows an example of the bag to which the strap shown in FIG. 1 is attached. It is a side view which shows the bag of FIG. It is a figure which shows a mode that the strap shown in FIG. 1 is used. It is a figure which shows an example of the edge part of a strap. It is a figure which shows an example of the use condition at the time of employ | adopting the structure of FIG. It is a figure which shows the collar part with the opening between a front-end | tip and a shaft open. It is a schematic diagram which shows the example of how to hook a strap.

  Hereinafter, the strap and bag of the present invention will be described with reference to the drawings.

[Strap embodiment]
First, an example of the strap of the present invention will be described with reference to FIG. FIG. 1 is a view showing an embodiment of the strap of the present invention.

  The strap 1 of the embodiment shown in FIG. 1 corresponds to an example of the strap of the present invention. The strap 1 is provided with the recesses 21 and 31 and the protrusions 22 and 32 of the snap button at intervals between the end portions 2 and 3, respectively. At the end portions 2 and 3, the end portions 2 and 3 can be formed into a ring by fastening the concave portions 21 and 31 and the convex portions 22 and 32. The strap 1 is provided with a length adjusting member 4, and the length of the strap 1 can be adjusted by changing the position of the length adjusting member 4.

  Next, the usage method of the strap 1 shown in FIG. 1 is demonstrated using FIGS. FIG. 2 is a front view showing an example of a bag to which the strap 1 shown in FIG. 1 is attached. FIG. 3 is a side view showing the bag of FIG. FIG. 4 is a diagram showing a state in which the strap 1 shown in FIG. 1 is used. In FIG. 4, the length adjusting member 4 is omitted.

  A bag 5 shown in FIGS. 2 and 3 is a bag body 51 to which a handle 52 that can be hung on a shoulder is attached, and is called a tote bag. As shown in FIG. 3, the handle 52 is attached to each of the front side and the back side of the bag body 51.

  As shown in FIG. 4, the strap 1 shown in FIG. 1 is used for the bag 5 with the handle 52 on the shoulder. Specifically, the both ends 2 and 3 are respectively wound around the handle 52 from the front side and the back side of the user through the armpit opposite to the side where the handle 52 is located. At this time, both end portions 2 and 3 of the strap 1 form a ring by fastening the concave portions 21 and 31 and the convex portions 22 and 32, and the handle 52 passes through the inside thereof. Yes. This state is also a state in which the rings of the end portions 2 and 3 of the strap 1 are hooked on the handle 52. In FIG. 4, the handle 52 is hung on the left shoulder. However, the handle 52 can be used in the same manner even when it is hung on the right shoulder.

  Furthermore, in use, the length of the strap 1 is adjusted using the length adjusting member 4 to fit the strap 1 to the user. When the strap 1 is shortened while the strap 1 is hooked on the handle 52, the force that the strap 1 pulls the handle 52 becomes stronger, and the handle 52 is bent. In this case, the handle 52 can be prevented from slipping off from the shoulder.

  Even if the handle 52 is not bent (the handle 52 is always pulled by the strap 1), the length of the strap 1 can be adjusted so that the strap 1 fits the user's body. That's fine. In this case, when the handle 52 tries to move in a direction in which the handle 52 slips off the shoulder, the strap 1 restricts this movement, and the handle 52 can be prevented from slipping off the shoulder. it can.

  In the state where the handle 52 is hung from the shoulder, the position of the bag 5 is mainly the side surface of the user and can be moved back and forth somewhat. For example, by shifting the bag 5 to the front of the user, the user can confirm the contents of the bag and can be prevented from being annoying in a crowded train. Further, for example, if the strap 1 is hooked on the handle 52 on the user side, the contents of the bag 5 can be easily confirmed. Thus, since the strap 1 described above does not require a change in the position of the bag 5 in use, it can be used without impeding the convenience of the bag 5.

  In addition, if the strap 1 is a bag which can be hung from a shoulder, a special structure is not required and the design of the bag itself is not limited. That is, a bag having a handle that can be worn on the shoulder can be used regardless of the design. For example, the handle may be a single bag.

  The configuration in which the strap 1 is hooked on the handle 52 is not limited to the snap button. However, in the case of the configuration using only the snap button as in the above embodiment, it can be easily attached to and detached from the handle 52. For example, if this strap 1 is used when riding a bicycle, the handle of the bag can be prevented from slipping off the shoulder, and after getting off the bicycle, the strap 1 is removed and only the bag is used. Therefore, the usage of the bag can be expanded.

  In addition, the strap 1 of embodiment described above is an example, and the structure which can employ | adopt other is demonstrated.

[About the configuration of the end]
In the strap 1 shown in FIG. 1, the configuration in which the snap buttons are provided at both end portions 2 and 3 has been described. However, the present invention is not limited to this snap button. The structure which provided the combination of the possible hole may be sufficient. That is, any combination that can be locked and that can form a ring that can be passed through the handle in the locked state. This combination corresponds to an example of the first locking portion and the second locking portion of the present invention.

  In a state where the first locking portion and the second locking portion are locked, another member serving as a stopper may be provided so that the ring does not come off or the ring is maintained even if it is removed. Good. However, for example, the strap 1 shown in FIG. 1 merely restricts the movement of the handle 52, and even if it is removed, the bag 5 does not fall immediately. Further, in view of the appearance of the bag 5, there is a possibility that the use of the strap 1 will be avoided. For these reasons, the strap may be required to be easily attached to and detached from the handle. In such a case, for example, like the concave portion 21 and the convex portion 22 of the strap 1, when the first locking portion and the second locking portion are unlocked simply by applying a force in the direction of separating them. At the same time, it is preferable that the ring disappears.

  In the configuration of the first locking portion and the second locking portion of the present invention described above, for example, a plurality of convex portions 22 and 32 of the end portions 2 and 3 in FIG. Moreover, it is good also as a structure with multiple positions which can be latched. In this case, the size of the rings of the both end portions 2 and 3 can be adjusted according to the thickness of the handle 52. Furthermore, by adjusting the locking position, the length of the strap 1 can be adjusted to match the size of the user's body.

  Furthermore, the strap 1 shown in FIG. 1 has a configuration in which the same surfaces of the strap 1 are combined when the snap button is locked, but as shown in FIG. 5, a configuration in which different surfaces of the strap 1 are combined. Also good. In this configuration, as shown in FIG. 5, the center axis of the ring formed at the end portion is inclined with respect to the extending direction of the strap 1, and the effect of making it difficult for the handle 52 to slip off the shoulder can be further enhanced. . This will be specifically described below.

  As shown in FIG. 4, when the strap 1 is hooked on the handle 52, the strap 1 is not in a horizontal state, but its position is lowered as it moves away from the handle 52. On the other hand, the handle 52 extends substantially in the vertical direction at the place where it is in contact with the strap 1. That is, at the location where the strap 1 and the handle 52 are in contact, the extending direction of the strap 1 and the handle 52 intersects diagonally without being orthogonal. Therefore, when the configuration of FIG. 5 is adopted, the ring at the end of the strap 1 can be fitted by the handle 52, and the effect of making the handle 52 difficult to slip off the shoulder can be further enhanced. . FIG. 6 shows an example of a usage situation when the configuration of FIG. 5 is adopted. From the above, the first locking portion and the second locking portion of the present invention may be locked on different surfaces of the strap 1.

  Furthermore, the configuration for hooking the strap 1 on the handle 52 is not limited to the configuration of the first locking portion and the second locking portion described above, and a configuration having a hook-like member (hereinafter referred to as a hook portion) is adopted. May be. In the case of this configuration, the handle 52 passes through the space inside the buttocks. Here, the entrance to this space (between the shaft and the tip of the collar) may be configured to be openable and closable as in the so-called NASCAN, or may be configured to remain open. FIG. 7 shows the flange 6 with the gap between the tip and the shaft open. In the heel part 6 shown in FIG. 7, since the space through which the handle 52 passes is always open, the strap 1 can be easily attached to and detached from the handle 52. As described above, when it is required that the strap 1 can be easily attached and detached, the configuration of the collar portion 6 may be used.

  In addition, in the strap 1 shown in FIG. 1, although the case where the both ends 3 and 2 were the same structures was demonstrated, the structure different in each ends 3 and 2 may be sufficient.

[How to hook onto the handle]
In the description of FIG. 4, the strap 1 shown in FIG. However, there is an effect that it is prevented from slipping off from the shoulder regardless of the portion to be hooked. Hereinafter, this point will be described with reference to FIG. The figure is a schematic diagram showing an example of how to hook the strap.

  8 (A) and 8 (B), the user's body B, the strap 1 disposed around the user's body B, and the root portions (four locations) of the handle 52 on the shoulder, The positional relationship seen from the direction is shown. In these drawings, the lower side corresponds to the front side of the user, and the upper side corresponds to the back side of the user. Further, among the fundamental portions of the handle 52, the side closer to the user is referred to as the inner side, and the side far from the user is referred to as the outer side, and is distinguished by combining the front side and the back side. Specifically, among the fundamental portions of the handle 52, those close to the user and on the front side are referred to as front inner sides (the handle 52a in FIG. 8), and those close to the user and on the back side are referred to as the back side. It is called the inside (the handle 52b in FIG. 8), the one far from the user and on the front side is called the front outside (the handle 52c in FIG. 8), and the one far from the user and on the back side is called the outside on the back. (Handle 52d in FIG. 8).

  First, FIG. 8A shows a state in which the strap 1 is hooked on each of the roots (the handles 52a and 52b) of the handle 52 on the inside. This state is an example, and the strap 1 may be hooked on the outer handle 52 (the handles 52c and 52d). Alternatively, the handles 52 adjacent to each other on the front side or the back side may be hooked together such that the handle 52a on the front inner side and the handle 52c on the outer front side are hooked together. Further, for example, when it is necessary to look at the contents of the bag 5 while the strap 1 is hooked on the outer handles 52c and 52d, for example, the strap 1 hooked on the outer handle 52c is temporarily moved to the front inner side. The contents of the bag 5 can be seen by hooking on the handle 52a. Thereafter, if necessary, the strap 1 may be hooked again on the handle 52c on the outer front side.

  Furthermore, when hooking the strap 1 on the handle 52, for example, the strap 1 on the front side of the user can be hooked on the handles 52b and 52d on the back side of the user, and the handle on the same side is not necessarily required. There is no need to hook 52. At this time, for example, as shown in FIG. 8B, when the strap 1 on the front side of the user turns around the handle 52c on the outer front side and hooks on the handle 52d on the outer back side. In addition, it is possible to be in a state of being hooked not only on the rear outer handle 52d but also on the front outer handle 52c.

  FIG. 8C shows a state in which the handle 52 is passed through the inside of the ring formed on one end 2 of the strap 1, but when the strap 1 is hooked on the handle 52, It is not limited to such usage. For example, as shown in FIG. 8D, when the strap 1 is wound around the handle 52, both the concave portion 21 and the convex portion 22 at the end portion 2 are folded back by the handle 52, and the end portion 2 is held by the handle. The strap 1 can be hooked on the handle 52 by wrapping around the strap 1 instead of 52 (the strap 1 is passed through a ring formed at the end 2). In this case, a ring is formed at a different location from the end 2 of the strap 1, and the handle 52 passes through the inside of the ring. The same can be applied to the above-described collar portion 6. For example, when the collar portion 6 is adopted as the end portion 2, the end portion 2 of the strap 1 can be folded back by the handle 52, and the collar portion 6 of the end portion 2 can be hooked on the strap 1 to form the strap 1. The handle 52 can pass through the inside of the ring.

  Further, as shown in FIG. 4, without hooking the end portions 2 and 3 on the handle 52, the handle 52 and the user are brought together and the strap 1 is made to go around, and the end portions 2 and 3 are locked together. (For example, the concave portion 21 and the convex portion 22 are engaged with the convex portion 32 and the concave portion 31 of the other end portion 3, or the hook portions 6 at both end portions are hooked together). At this time, the strap 1 passes through the upper portion of the bag body 51. In this case, a single ring is formed not by the end portions 2 and 3 but by the entire strap 1, and the handle 52 and the user pass through this ring. Even in this case, the strap 1 is hooked on the handle 52.

  In other words, the strap 1 only needs to be hooked on the handle 52 regardless of the method and configuration, and the handle 52 can be prevented from slipping off the shoulder.

  In addition, when there are two handles 52, it is preferable that the handle 52 on the outer side as viewed from the user is hooked. Further, the handle 52 is hooked on both the front side and the back side of the user. It is preferable that

[About length adjustment]
As described above, when the strap 1 is hooked on the handle 52, various methods can be adopted. However, the length of the strap 1 that goes around the user differs depending on these methods. For example, comparing the cases of FIG. 8A and FIG. 8B, the strap required in the latter case is longer. In other words, the strap 1 can be fitted to the user's body to some extent without using the length adjusting member 4 by making the hooks of the strap 1 different. For this reason, although the length adjustment member 4 is not essential, in order to match a user's body, it is preferable that there is the length adjustment member 4. Further, the length adjusting member 4 is not limited to the configuration of the strap 1 shown in FIG. 1. For example, an elastic member such as rubber is used for the material of the strap 1, so that the length of the elastic member is changed to the length adjusting member. It is good.

[About a configuration with a bag added]
In the strap 1 of the embodiment described above, the configuration in which the strap 1 is hooked from the front side and the back side of the user with respect to the handle 52 that can be hung on the shoulder has been described. In this configuration, as long as the handle of the bag can be worn from the shoulder, no other configuration is required. However, it is possible to achieve the same effect even when the bag side configuration is adopted and the bag is attached with a strap.

  For example, the convex portion 22 provided on the end portion 2 of the strap 1 shown in FIG. 1 is provided not on the strap 1 but on the handle 52 of the bag 5 shown in FIG. 2 so that the handle 52 and the strap 1 can be connected. Good. When the configuration in which the collar 6 shown in FIG. 7 is provided at the end 2 of the strap 1 is adopted, an annular member such as a D-can is provided on the handle 52 and the collar 6 is hooked on the annular member. Thus, the handle 52 and the strap 1 may be connectable. In addition, one of the pair of connecting members such as the concave and convex portions of the eggplant and the D-can and the insertion buckle is provided on the end of the strap, and the bag is provided with the other on the handle. The handle can be connected to the strap. As in these examples, if the bag is configured to have a connection part that can connect the strap to the handle, the handle will not fall off the shoulder, similar to the configuration in which the strap is hooked to the handle of the bag. can do. Further, the structure of the bag that is fixed so that the handle and one end of the strap cannot be separated from each other can be prevented from falling off the shoulder as in the structure in which the strap is hooked on the handle of the bag.

  The above configuration is for a strap that is arranged from "the front side and the back side of the user through the armpit on the side opposite to the side with the handle on the shoulder". By adding a configuration to the hand, the strap 1 shown in FIG. As an example of these combinations, “the straps from the front side and the back side are connected to the first connection part and the second connection part provided on the handle” (corresponding to the first bag of the present invention) Or a configuration (corresponding to the second bag of the present invention) in which one of the straps from the front side and the back side is connected to a connecting portion provided on the handle and the other is hooked on the handle. And one end of the strap from the back side is fixed to the handle, and the other is connected to the connecting portion provided on the handle (corresponding to the third bag of the present invention) One end of the strap is fixed to the handle and the other is hooked on the handle ”(corresponding to the fourth bag of the present invention).

  In the configuration of the bag described above, the configuration similar to the configuration described in the embodiment of the strap 1 shown in FIG. Moreover, in the structure of said bag, when the structure which fixed the end of the strap to the handle is employ | adopted, it can prevent losing a strap.

  The above bag configuration employs a configuration in which the strap is attached directly to the handle so that the handle does not slip off, but the handle will slip even if it is attached to a location other than the handle. It can be prevented from falling. As an example, a description will be given of the configuration of a bag provided with D cans at both ends in the longitudinal direction of the bottom and a strap provided with eggplants at both ends (corresponding to an example of the fifth bag of the present invention). In this configuration, the straps are placed from the front and back sides of the user around the torso opposite to the side with the handle on the shoulder, and the nascars on both ends of the strap are placed on the bottom of the bag. And connected to D cans (corresponding to an example of the first connection portion and the second connection portion in the fifth bag of the present invention) at both ends of each. In this state, the shaking of the bag body can be suppressed, and as a result, the handle can be prevented from slipping off the shoulder. In addition, about the structure which can connect a bag bottom part and a strap, it is not limited to said example, For example, the structure similar to the structure which can connect the handle of a bag and a strap mentioned above is employ | adopted. can do. In addition, when a leg is provided at the corner of the bottom of the bag, a part thinner than the other part is formed on a part of the shaft of the leg, and members that can be engaged with the shaft are provided at both ends of the strap. The bag bottom and the strap may be connectable. As described above, by providing the connection part to which the strap can be connected to the bottom of the bag, the bag can be prevented from shaking and the handle can be prevented from slipping off the shoulder. In addition, about said connection part, it is preferable that it is the both ends side of the longitudinal direction of a bag bottom part.
