Description

  The present invention relates to a backpack bag. More particularly, the present invention relates to an improvement in the construction of the shoulder belt in a backpack bag of the type carried by the shoulders of the user.

  Backbags, such as backpacks, are usually carried on the user's back via a pair of shoulder belts (shoulders) which are hung on the user's shoulders. In particular, a backpack bag suitable for climbing or hiking has a relatively large-capacity bag body, and the user often carries on the back for a long time with a relatively heavy luggage content stored in the bag body. There are also cases where the user walks with such a luggage or climbs up and down a steep slope.

  In this way, when walking or climbing up and down with a backpack or the like, it is desirable that the load of the carried luggage uniformly act on the user's shoulders to the back, and that condition is the movement of the user and It is desirable to be maintained even during exercise. On the other hand, if there is a gap between the back of the user and the back bag, not only is it difficult to obtain a sense of unity with the back bag, but also the luggage is likely to swing to the left and right, so the problem of lack of stability. Will occur.

  Normally, when there is a gap between the user's back and the backpack, the user lifts the backpack and shifts the position of the backpack upward to eliminate the gap, and stability is achieved. The action to try to improve The number of such movements tends to increase, especially when the backpack is loaded with heavy luggage.

  In addition, when carrying a back bag or carrying a back bag, an action to improve the stability by adjusting (generally shortening) the overall length of the shoulder belt is also occasionally seen. Conventionally, as such a backpack, there has been proposed a bag in which the position of a shoulder belt can be adjusted according to the physical constitution of the user (see, for example, Patent Documents 1 and 2).

Japanese Utility Model Publication No. 58-43885 Japanese Utility Model Publication No. 59-1533

  However, in the conventional backrest bag as described above, the motion for the user to lift the backbag and the like to eliminate the gap with the back and the motion for adjusting the overall length of the shoulder belt are different motions. It is usually that Therefore, the user performs these actions separately on the left and right, respectively, in order to improve the sense of unity with the backpack bag without feeling any particular doubt or discomfort.

  Therefore, an object of the present invention is to provide a back bag that can simultaneously perform the operation for adjusting the length of the shoulder belt and the operation for pulling the bag body toward the user's body in one action. Do.

  The present inventor examined in order to solve this subject. As described above, due to the structure of the conventional backrest bag, there is a problem in that the movement to eliminate the gap by carrying up the backbag and the like and the movement to adjust the entire length of the shoulder belt are separate I have no sense of incongruity. For this reason, although the motivation and the point of view for trying to complete these operations simultaneously in one action are very poor in the first place, the inventor considers a distinctive structure different from the conventional one. As a result of getting around, we came to get new knowledge.

  The backpack bag according to the present invention is based on such findings, and is guided by a bag body, a shoulder strap disposed at a position to be hung on the shoulder of the user with respect to the bag body, and the shoulder strap. It is relatively movable in the longitudinal direction of the shoulder strap, and one end is directly or indirectly connected to the bag body, is folded back near the other end, and the other end is fixed to a part of the shoulder strap And a lower webbing having an upper webbing, one end directly or indirectly connected in a displaceable state relative to the upper webbing, and the other end fixed near the bottom of the bag body. The user carrying the back bag pulls a portion of the upper webbing to draw the bag body toward the user's body, and the other end of the upper webbing is Folding is the adjustment operation of the length, it can conduct simultaneously.

When the user pulls the upper webbing toward the user while carrying the backpack, the following operations (A) and (B) are simultaneously performed.
(A) One end of the upper webbing is pulled forward (to the front of the user). Along with this, the bag body to which the one end portion is directly or indirectly connected is drawn forward (to the side of the user's body) to reduce or eliminate the gap with the back of the user.
(B) When the upper webbing is pulled forward, the relative position of the upper webbing to the shoulder strap changes by the pulled out part, while the other end of the upper webbing is fixed to a part of the shoulder strap Because of this, as the relative position changes in this way, the turn-back portion (the position of the turn-back portion) of the upper webbing also changes. As described above, when the position of the folded portion changes, the folded length (the length of the portion where the folded upper webbing overlaps to form two layers) also changes. As a result, the overall length of the shoulder belt (shoulder) becomes short.

  On the other hand, in the case of the conventional backrest bag, the portion for adjusting the overall length of the shoulder belt body and the portion for pulling the bag body (load) are independently configured, and the overall length of the shoulder belt body is adjusted If it is attempted, an operation for adjusting the left and right, respectively, is required, and separately from this, an operation for pulling the bag body must be separately performed, and the adjustment is required twice. On the other hand, according to the backpack according to the present invention, which achieves the above-described operation, the length adjustment operation of the shoulder belt and the operation of pulling the bag body toward the user's body simultaneously in one action. It can be carried out.

  Moreover, in the case of the conventional backrest bag, the portion for adjusting the overall length of the shoulder belt main body and the portion for pulling the bag main body (load) are configured independently, but in the backrest bag according to the present invention Can be configured to have the functions of both parts in some parts. Therefore, it is possible to reduce the number of parts used compared to the conventional structure, and to achieve weight reduction and cost reduction.

  Preferably, a loop portion is formed on the shoulder strap, and the upper webbing can slide in the loop portion in the longitudinal direction of the shoulder strap in a slidable state. If the frictional force between the shoulder strap and the upper webbing is appropriately secured, it is difficult for the shoulder strap and the upper webbing to shift after adjustment, and the relative position between the two is easily maintained.

  Further, in the above-described backpack bag, the upper webbing and the lower webbing may be connected via fasteners. Furthermore, in such a backpack, it is preferable that the upper webbing be folded back from the front to the back of the user at the fastener.

  In the backpack according to the present invention, the backpack has a frame serving as a skeleton, and the shoulder strap is substantially connected to the frame so that the weight of the bag body is transmitted through the frame. Can be. In this case, the user can pull the upper webbing toward the front side while carrying the back bag, thereby drawing the entire back bag forward (to the user's body) via the frame (skeleton). In such a backpack, one end of the upper webbing may be connected to the frame.

  According to the present invention, it is possible to simultaneously perform the operation for adjusting the length of the shoulder belt and the operation for drawing the bag body toward the user's body in one action.

It is a side view of the state carried by the user which shows an example of the backpack bag to which this invention is applied. It is a side view which shows the mode of the bag bag at the time of pulling out a part of upper webbing to the near side from the state shown in FIG. It is a side view of the backpack bag which shows a mode that the length of a shoulder belt becomes short automatically, after releasing a part of upper webbing pulled out to the front. It is a perspective view showing an example of composition of a frame built in a back bag, upper webbing connected to the frame, lower webbing, etc.

  Hereinafter, the configuration of the present invention will be described in detail based on an example of the embodiment shown in the drawings.

  1 to 4 show an embodiment of a backpack according to the present invention. Below, the case where this invention is applied to a backpack as an example is illustrated and demonstrated. The backpack 1 according to this embodiment includes a bag body 2, shoulder straps 3, a frame 4, an upper webbing 5, a buckle 6, a lower webbing 7, and the like (see FIG. 1 and the like).

  The bag body 2 is usually constituted by a woven or non-woven fabric of natural fibers or synthetic fibers, and has appropriate flexibility and rigidity. The bag body 2 of the present embodiment is formed in a bottomed bag shape as a whole, and a luggage storage space is formed inside, and a lid (not shown) is attached to the upper portion thereof. The back (the side in contact with the back of the user) 26 of the bag body 2 is formed substantially flat according to the back of the user, and a cushioning material 27 for enhancing the sense of contact with the back is appropriately disposed on the entire surface or a part There is. A frame insertion portion 22 for storing the frame 4 is formed on the back side of the back surface 26 of the bag body 2. Further, on the back surface 26, a pair of left and right shoulder belts (shoulders) 10 are disposed.

  The shoulder belt (shoulder) 10 is a portion that the user hangs on both shoulders when carrying the backpack 1 on his back. The shoulder belt 10 in the backpack 1 of the present embodiment is configured of a shoulder strap 3, an upper webbing 5, a buckle 6, and a lower webbing 7.

  The shoulder strap 3 has a symmetrical structure, and is disposed at a position where it can be hung on the shoulder of the user with respect to the bag body 2. The shoulder strap 3 of the present embodiment is V-shaped as a whole in a state in which the left and right are attached to the shoulder strap support 35 (see FIG. 4). Further, a loop portion 3 a is formed on the shoulder strap 3, and the upper webbing 5 is slidably passed through the loop portion 3 a.

  The frame 4 forms a skeleton so that the entire shape of the backpack 1 is maintained, and the frame 4 has a shape in which a metal material having a predetermined elasticity and rigidity is circulated in a predetermined shape (FIG. 1) Etc.). The frame 4 is inserted into the above-mentioned frame insertion portion 22 formed on the back surface 26 of the bag body 2. The material of the frame 4 includes, but is not limited to, a rod, a wire or a pipe made of, for example, aluminum and having appropriate strength and rigidity and flexibility. Such a frame 4 imparts structural strength and rigidity to the back surface 26 of the bag body 2 and, by exhibiting appropriate flexibility, matches the frame 4 itself to the shape of the user's back, And it is possible to hold that position. Depending on the material, it is also possible for the user to adjust the shape of the frame 4 by hand and fit it to his / her back without using any special equipment. Adjustment of the frame 4 in this case can be performed in a state where the frame 4 is disposed in the bag body 2, but if the frame 4 is configured to be easily taken out of the bag body 2, the adjustment is easier It can also be

  The upper webbing 5 is relatively movable in the longitudinal direction of the shoulder strap 3 by sliding so as to be offset with respect to the shoulder strap 3. One end 5 a of the upper side (shoulder side of the user) of the upper webbing 5 is connected to the bag body 2. Further, the lower side (the waist side of the user) of the upper webbing 5 is a folded portion 5c which is folded back after passing through the buckle 6, and the other end 5b is fixed to the end of the shoulder strap 3 ( See Fig. 1 etc.). The folded portion 5c of the upper webbing 5 in the present embodiment is formed by folding the other end 5b from the front to the back of the user with respect to the buckle 6 (see FIG. 1).

  Further, it is preferable that the upper webbing 5 be such that the relative frictional force to the shoulder strap 3 is appropriately secured. In such a case, the relative position between the shoulder strap 3 and the upper webbing 5 is difficult to shift, and the relative position between the two is different except when the user adjusts the length of the shoulder belt (shoulder) 10 or pulls the bag body 2. It becomes easy to be kept. In the present embodiment, as described above, the loop portion 3a is formed on the shoulder strap 3 and the upper webbing 5 is slidably passed through the loop portion 3a so that an appropriate frictional force acts between the two. It is like that. In this case, by appropriately combining the width, thickness, material, surface treatment of the contact surface, and the like of the shoulder strap 3 and the upper webbing 5, it is possible to change the specific frictional force (difficult to shift in relative position).

  The buckle (fastener) 6 is a fastener that indirectly connects the upper webbing 5 and the lower webbing 7. At the upper part of the buckle 6, the lower part of the upper webbing 5 is passed and folded back (see FIG. 1). In the lower part of the buckle 6, one end 7a of the upper part of the lower webbing 7 is passed, folded back and passed through the buckle 6 again, and the lower webbing 7 is in contact by surface contact with each other. It is configured to generate a frictional force that does not shift the relative position of the parts (see FIG. 1 and the like). The user pulls out the folded portion of the lower webbing 7 in the buckle 6 and loosens it once, and changes the folded position, so that the length of the shoulder belt (shoulder hook) 10 (via the buckle 6 from one end 5 a of the upper webbing 5) The length of the lower webbing 7 up to the other end 7b can be adjusted.

  The lower webbing 7 is a member that connects the upper webbing 5 and the bag body 2 via the buckle 6. One end 7a of the lower webbing 7 is folded back by a buckle 6 and normally locked, while the lower webbing 7 is pulled out or pushed in and released from the buckle 6 to shift the position. , The amount of withdrawal from the buckle 6 can be changed. Thus, the relative position of the lower webbing 7 with respect to the upper webbing 5 of the one end 7a can be displaced, and the length from the buckle 6 to the other end 7b of the lower webbing 7 can be adjusted. . The other end 7b of the lower webbing 7 is connected to the lower portion of the bag body 2 (see FIG. 4 and the like). The other end 7 b of the lower webbing 7 may be connected not by the frame 4 but by a predetermined location of the bag body 2 or the like.

  In the backpack 1 of the present embodiment configured as described above, the length adjustment operation of the shoulder belt (shoulder) 10 and the operation of drawing the bag body toward the user's body are simultaneously performed in one action. (See FIGS. 1 to 3).

  That is, in a state where the user carries the backpack 1 (see FIG. 1), for example, the left and right thumbs inserted from both sides into the folded portion 5c of the upper webbing 5 are shifted forward etc. When it is pulled out to the front side, one end 5a of the upper webbing 5 is pulled out to the front (the front side of the user). Along with this, the bag main body 2 is pulled forward (the user's body side) together with the contents accommodated in the bag main body 2 in some cases through the frame 4 to which the one end 5a is connected See Figure 2). Then, the gap (indicated by symbol S in FIG. 1 and the like) generated between the backpack 1 and the back of the user is reduced or eliminated.

  Thus, when pulling out a part of the upper webbing 5 to the front, the shoulder strap 3 in contact with the shoulder of the user is basically positioned except when the upper webbing 5 is drawn to the front very strongly. Never change (see Figure 2). Therefore, when the upper webbing 5 is pulled out to the front, the relative position of the upper webbing 5 with respect to the shoulder strap 3 changes in proportion to the pulling out. At this time, since the other end 5 b of the upper webbing 5 is fixed to a part of the shoulder strap 3, the position of the folded portion 5 c of the upper webbing 5 also changes as the relative position changes. Thus, when the position of the folded portion 5c changes, the folded length (the length of the portion where the folded upper webbing 5 overlaps to form two layers, and the length from the other end 5b to the folded portion 5c) Also applies)). Therefore, in the backpack 1 of the present embodiment, after the user pulls a portion of the upper webbing 5 forward, if the pulled out portion is released, a shoulder belt (shoulder) 10 is obtained according to the amount pulled out. (The length from one end 5a of the upper webbing 5 to the other end 7b of the lower webbing 7 via the buckle 6) is automatically shortened (see FIG. 3).

  As described above, the length adjustment operation of the shoulder belt 10 and the operation of pulling the bag body 2 toward the user's body in one action in which the user pulls a portion of the upper webbing 5 forward. At the same time. The shoulder belt 10 of the backpack 1 according to the present embodiment, which realizes such a motion, functions as a so-called stabilizer that reduces the swinging of the load from side to side during walking or the like to improve the stability.

  Moreover, in the backpack 1 of the present embodiment, both of the length adjustment function of the shoulder belt 10 and the function of pulling the bag body 2 toward the user's body in some parts (the shoulder strap 3 and the upper webbing 5). It has a configuration that combines Therefore, compared to a backpack (back and shoulder bag) in which the length adjustment portion of the shoulder belt 10 and the portion for pulling up the bag body (load) are independently configured, parts necessary to realize the function are obtained. There is also an advantage that it is possible to reduce the weight, to reduce the weight, and to reduce the cost.

  The above-described embodiment is an example of the preferred embodiment of the present invention, but is not limited to this, and various modifications can be made without departing from the scope of the present invention. For example, in the embodiment described above, it has been described that the length adjustment operation of the shoulder belt (shoulder) 10 and the operation of pulling the bag body 2 toward the user's body can be simultaneously performed in one action. The term "simultaneous" is not strictly limited in the strict sense. That is, "simultaneous" as used herein means that two (two types of) actions that were previously performed separately can be performed at one time by a series of consecutive movements caused by one action. In a strict sense, this does not mean that both operations are simultaneously performed.

  In the above embodiment, one end 5 a of the upper webbing 5 is connected to the bag body 2, the other end 5 b is fixed to the shoulder strap 3, and one end 7 a of the lower webbing 7 passes through the buckle 6. And the other end 7b is connected to the bag main body 2, but the "one end" and the "other end" described in the above description are not limited to the ends in a strict sense. . That is, for example, there may be a state in which a string or the like continues to the end of each end, but in consideration of the function for achieving the function and effect of the present invention, each configuration has the same configuration. It should be considered that the present invention also includes an arrangement in which a string or the like continues from the end first.

  Further, in the above-described embodiment, the upper webbing 5 is directly connected to the bag body 2 (see FIG. 1 and the like). In addition, by attaching one end 5a of the upper webbing 5 to the frame 4 The upper webbing 5 may be connected indirectly to the bag body 2.

  Further, although not particularly described in the above embodiment, the backpack (backless bag) 1 includes a hip belt or the like for fixing the lower end portion of the bag body 2 more securely to the user. It is also good. The hip belt is, for example, configured such that its center coincides with the position near the lower part of the user's spine.

  Moreover, although the above-mentioned embodiment demonstrated the example which applied this invention to the backpack as an example of a back bag, this invention is not limited to this, and what is called a so-called knapsack and a rucksack It is also possible to adapt to bags.

  Moreover, although the above-mentioned embodiment showed the backpack 1 which includes the buckle (fastener) 6 in a structure, this is also a preferable example. Although not particularly illustrated, in addition, for example, a slit is provided in the vicinity of one end 7a of the lower webbing 7, and a buckle is omitted by folding the other end 5b of the upper webbing 5 through the slit. It is also possible.

  The present invention is suitable to be applied to backpacks and other backpack bags of the type that is carried on the shoulders of the user.
