Description

[Technical field]

[0001] The present invention relates to a backpack, and in particular to an improvement in a backpack that allows a small item bag, in which valuables and the like are often separately placed, to be put in and taken out while the backpack is being worn. [Background technology]

[0002] Backpacks are used not only for travel but also for everyday use because they allow you to carry your belongings on your back and leave your hands free to move around. When using such a backpack, cash, valuables, etc. are often placed in a small item bag, which is then stored inside the backpack. Although this type of usage is easy to handle because the items are stored separately, when taking out the small item bag, it is necessary to take off the backpack first, which is quite inconvenient.

[0003] In order to eliminate such inconvenience, backpacks with pouches have been proposed that allow a user to take out and put in a small bag (pouch) while still wearing the backpack (see, for example, Patent Document 1). This device stores pouches connected to a chain reel inside the backpack from the side, allowing the pouches to be taken in and out while the backpack is on the back, but does not take into consideration security. In other words, when the pouch is stored in the opening on the side of the backpack, the clip attached to the pouch is exposed to the outside through the opening, which makes it vulnerable to being stolen from behind by unscrupulous persons.

[0004] [Patent Document 1] Patent Publication No. 2018-50861 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in consideration of the above-mentioned background, and has as its technical object to develop a new backpack which allows a small item bag to be easily inserted and removed while the backpack is being worn on the back without having to be taken off, and which also prevents items from being stolen from the outside. [Means for solving the problem]

[0006] That is, the backpack described in claim 1 has a lower storage section below a storage section of the backpack body equipped with shoulder belts, this lower storage section is connected to the outside by providing an opening on at least one side of the backpack body, and a closure flap is provided at the opening, and a small item bag separate from the backpack body is incorporated in the lower storage section, and this small item bag has an pull-out strap and a return strap attached to each side of the small item bag in opposite directions, and the free ends of these straps are pulled out to the outside of the backpack body, so that by pulling the pull-out strap while the backpack body is on the back, the small item bag can be removed from the opening with the closure flap opened, and by pulling the return strap, the small item bag can be stored in the lower storage section.

[0007] In addition to the above requirements, the backpack described in claim 2 is characterized in that the free ends of the pull-out strap and the return strap are configured so that they can be hooked onto a shoulder belt.

[0008] In addition to the above requirements, the backpack described in claim 3 is characterized in that the closure flap that closes the opening is configured to be able to maintain an open state. Effect of the Invention

[0009] First, according to the invention described in claim 1, the accessory bag can be removed from the backpack body and stored in the backpack body while the backpack body is still on the user's back, which relieves the user of the inconvenience. Furthermore, when the accessory bag is stored in the lower storage section, the opening is closed by a closure flap, which prevents the fact that the accessory bag is stored in the lower storage section from being noticed from the outside.

[0010] According to the invention described in claim 2, the pull-out strap and the return strap can be integrated with the shoulder belt, so that the bag can be neatly stored without getting in the way. Furthermore, the return strap is hooked to the shoulder belt, so that the small item bag can be prevented from being pulled out of the lower storage compartment.

[0011] Furthermore, according to the invention described in claim 3, the closure flap can be kept open when the small item bag is taken in and out of the lower storage section, thereby preventing the closure flap from flapping about and getting in the way. [Brief description of the drawings]

[Figure 7]1 is a perspective view showing a step-by-step usage state of the backpack of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0013] The backpack P of the present invention will now be described in detail. This backpack P has as its main components a backpack body 1 and a small item bag 2, which are assembled together. In this specification, the surface of the backpack P seen from behind when the user is wearing the backpack P is the front of the backpack P (Figure 2(a)), and the surface on which the shoulder belt 3 is provided is the back (Figure 2(b)).

[0014] First, the backpack body 1 will be described. This is a bag-like body of appropriate capacity that can be opened and closed, for example, by a slide fastener 11 provided within a certain range from the top to both sides, and is provided with a pair of shoulder belts 3 for carrying the backpack on the back. In the following description, when a pair of left and right members are to be treated separately, the left and right members will be denoted by the symbols L and R in the drawings, respectively.

[0015] This shoulder belt 3 is provided with an adjuster 31 so that it can be set to an appropriate length according to the user's physique, etc., and also has a branching strap 32 in the middle, and further has a buckle piece 33 at the end thereof for connecting the pull-out strap 6 or the return strap 7 provided on the small item bag.

[0016] Furthermore, the storage section 5 which is the internal space of the backpack body 1 is divided into an upper storage section 5A and a lower storage section 5B, and the accessory bag 2 is stored in the lower storage section 5B. As one example, the lower storage section 5B is preferably constructed of a casing 51 having the strength to maintain a constant shape, and this casing 51 is configured with an opening 52 on a side of the backpack body 1, at least one side as one example, as the opening 52 to connect the lower storage section 5B to the outside.

[0017] In addition, a closure flap 53 is provided at the opening 52 and is fixed to the backpack body 1. As an example, the free end of the closure flap 53 is shaped so that it can be opened and closed like a door, with the shoulder belt 3 side of the backpack body 1 being in the free state (see Figure 4).

[0018] A closing hook-and-loop fastener 53A is provided on the free end side of the inner surface of the closure flap 53, and an opening hook-and-loop fastener 53B is provided on the outer surface thereof. Corresponding to the closing hook-and-loop fastener 53A, the backpack body 1 is provided with a closing flap receiving hook-and-loop fastener 13A, while corresponding to the opening hook-and-loop fastener 53B, a closing flap opening hook-and-loop fastener 13B is provided. As a result, these hook-and-loop fasteners maintain the opening 52 in a closed or open state by the locking action of their respective locking mating elements, i.e., the loop and hook.

[0019] Next, a description will be given of the small item bag 2. This may be any bag that has an appropriate storage form such as a pouch or waist bag, and in this embodiment, a bag that is substantially rectangular and opens and closes with a slide fastener 21, for example. The accessory bag 2 is provided with a pull-out strap 6 that extends along one side of the bag. A buckle piece 61 is provided on the free end of the pull-out strap 6, and an adjuster 62 is provided midway through the buckle piece 6, allowing the length of the pull-out strap 6 to be adjusted.

[0020] Furthermore, a return strap 7 is provided so as to extend on the side opposite to the pull-out strap 6 in a front view. This return strap 7 also has a buckle piece 71 on its free end side, and an adjuster 72 for adjusting the length of the return strap 7.

[0021] The pull-out strap 6 is attached to the small item bag 2 in correspondence with the non-closed space 53S described later, for example by being sewn to the upper part of the back surface of the small item bag 2 over substantially the entire lengthwise area. On the other hand, the return strap 7 is attached to the small item bag 2 by, for example, sewing it to the bottom surface of the small item bag 2 over substantially the entire lengthwise area in correspondence with a strap slit 12 described below.

[0022] The closure hook-and-loop fastener 53A of the closure flap 53 is not provided over the entire range in the vertical direction, but a non-closing space 53S, which is a portion in the vertical direction that is in an unclosed state, is provided. When such a non-closing space 53S is provided, when the small bag 2 is stored in the lower storage section 5B and the closure flap 53 is closed, the pull-out strap 6 is pulled out through the non-closing space 53S, so that the closed state of the closure flap 53 is maintained even if force is applied to the pull-out strap 6 due to vibrations caused by walking, etc. On the other hand, the return strap 7 is assembled so as to be pulled out to the outside from a strap slit 12 provided on the side of the backpack body 1 .

[0023] The configuration of the present invention adopts the above-mentioned form as an example, and is used as follows. First, the initial state is a state in which the accessory bag 2 is stored in the storage section 5 of the backpack body 1 as shown in FIG. 6(a). In this initial state, the accessory bag 2 is contained within the casing 51 constituting the lower storage section 5B in the storage section 5, and the withdrawal strap 6 is pulled out to the outside from the non-closing space 53S in which the closing flap 53 in the closed state does not have a closing hook-and-loop fastener 53A. The buckle piece 61 on the free end side of the pulling strap 6 is connected to the buckle piece 33 provided on the branch strap 32 .

[0024] The connection between buckle piece 61 and buckle piece 33 is a pair of buckle piece elements of a so-called side push type buckle, which is relatively easy to use; however, since what is required is to connect the pull-out strap 6 and the branch strap 32, the connection is not limited to this type of connection. For example, another connection configuration can be adopted in which a ring-shaped connection ring or the like is provided on the branch strap 32, and a so-called snap hook, carabiner, or the like is provided at the end of the pull-out strap 6 to engage with this. Of course, a fastening means may be provided such that a hook-and-loop fastener element piece is provided on the free end of the pull-out strap 6 in relation to the annular connecting ring or the like, and the pull-out strap 6 is passed through the ring-shaped connecting piece and fastened with the hook-and-loop fastener or the like. Furthermore, the method of fastening the pulling strap 6 may be a method of directly fastening the pulling strap 6 to the shoulder belt 3.

[0025] On the other hand, the return strap 7 of the small bag 2 is pulled out from the strap slit 12 of the backpack body 1 to the outside, and the buckle piece 71 on the free end side of the tip is connected to the buckle piece 33 provided on the branch strap 32 provided on the other shoulder belt 3. Needless to say, when connecting the buckle piece 71 to the buckle piece 33, other means may be used as appropriate instead of the connection between the buckle piece 61 and the buckle piece 33 described above.

[0026] In this state, as shown in FIG. 1, the user uses the backpack P by hanging the shoulder belts 3 of the backpack body 1 on both shoulders. When it becomes necessary to take out the small bag 2, as shown in Fig. 6(b), the user first releases the fastening between the fastening hook-and-loop fastener 53A of the fastening flap 53, which has been closing the opening 52 of the storage section 5, and the fastening hook-and-loop fastener 13A for receiving the fastening flap on the backpack body 1 side, and then performs an operation such as rolling back the fastening flap 53, for example. This operation causes the fastening hook-and-loop fastener 53B for opening the fastening flap 53 to engage with the fastening hook-and-loop fastener 13B for opening the fastening flap on the backpack body 1 side, maintaining the open state (see Fig. 4).

[0027] After achieving this state, the user releases the engagement between the buckle piece 61 of the pulling strap 6 and the buckle piece 33 on the branch strap 32 side, and between the buckle piece 71 of the return strap 7 and the buckle piece 33 on the branch strap 32 side, as shown in Figure 6(c), thereby freeing the free ends of the pulling strap 6 and the return strap 7. In this state, when the user pulls out the pull-out strap 6 in front of the body as shown in Figure 6(d), the accessory bag 2 is pulled out of the casing 51 in the storage section 5 and then pulled towards the user's hand as shown in Figure 7(e). In this manner, the small bag 2 can be operated in the usual manner, that is, by opening the slide fastener 21 etc., and removing the necessary items from inside.

[0028] When the user wants to put the small bag 2 back into the storage section 5, the user closes the slide fastener 21 of the small bag 2 and pulls the return strap 7 in front of the body as shown in Fig. 7(f). This operation moves the small bag 2 so that it is pulled back into the casing 51 of the storage section 5. In this state, the user closes the closure flap 53 again as shown in Figure 7(g), and engages the buckle piece 61 of the pull-out strap 6 with the buckle piece 33 on the branch strap 32 side as shown in Figure 7(h), and further engages the buckle piece 71 of the return strap 7 with the buckle piece 33 on the branch strap 32 side to return to the initial state.

[0029] At this time, the return strap 7 is preferably set so that the adjuster 72 keeps the small bag 2 sufficiently contained within the casing 51, and further, when the return strap 7 is fastened to the shoulder belt 3, there is no play in the length direction of the return strap 7. In this case, even if another person tries to forcibly pull out the small bag 2 from the storage section 5, the small bag 2 remains stored in the casing 51 by the return strap 7, so that the small bag 2 will not be pulled out from the casing 51 of the storage section 5. Also, by again fastening the free end of the pulling strap 6 to the shoulder belt 3, it is possible to maintain a state in which the pulling strap 6 is not pulled out accidentally.
