Description

[Technical field]

[0001] The present invention relates to a backpack, and in particular to a reversible backpack. [Background technology]

[0002] A reversible backpack has been proposed in which the shoulder straps (called shoulder straps in Patent Document 1) are detachable from the main body of the bag (see Patent Document 1, for example). In this backpack, a zipper (not an open zipper) with two sliders attached to the top of the bag is attached continuously from the bottom to the right side, top, left side and bottom of the main body of the bag, so that when the zipper is fully opened, the front and back sides of the main body of the bag can be turned inside out. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-296560 A (paragraphs 0013, 0030, FIG. 6) Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the backpack disclosed in Patent Document 1, the shoulder straps are detachably attached to the bag body with fasteners so that they can be removed from the bag body, which means that the strength is inferior to that of regular sewing. In particular, the shoulder strap attachment points bear the most weight, which makes the backpack disclosed in Patent Document 1 uneasy in terms of strength.

[0005] In addition, as described in the above-mentioned Patent Document 1, reversible bags that can be used by turning the front and back sides inside out were limited to handbags. Furthermore, because the shoulder straps of a backpack are longer than the handles of a handbag, the idea of ​​making a backpack reversible had not been thought of.

[0006] Therefore, the object of this invention is to solve the above-mentioned problems and to provide a reversible backpack that is unique to backpacks, without being limited to the definition of a reversible bag, which means that the front and back of the bag can be turned inside out and used. [Means for solving the problem]

[0007] In order to solve the above problem, in the invention according to claim 1, an open zipper is attached around the entire circumference in the vertical dividing direction of the backpack.

[0008] In the invention according to claim 2, the backpack is split vertically at the joint between the front body and the gusset.

[0009] In the invention according to claim 3, the open fastener is a double slider having two sliders attached head to head. Effect of the Invention

[0010] According to the invention of claim 1, a backpack having a back body with shoulder straps, a front body, and a gusset is provided with an open zipper around the entire circumference in the vertical direction of the backpack, so that by opening and closing the open zipper, the front body, etc. can be freely attached and detached from the back body, etc. with shoulder straps.

[0011] According to the invention of claim 1, the front torso can be freely attached and detached from the back torso equipped with shoulder straps, so that the detached front torso can be turned over and reattached. If the front and back of the front torso have different designs, the front torso can be turned over and two designs can be enjoyed.

[0012] Furthermore, according to the invention as defined in claim 1, the front torso can be freely attached and detached from the back torso equipped with shoulder straps, so the shoulder straps, which bear the greatest load, can be attached by sewing as in the past. Therefore, according to the invention as defined in claim 1, the strength of the rucksack, specifically the strength of the shoulder strap attachment parts, is not compromised as in the rucksack as defined in Patent Document 1.

[0013] According to the invention of claim 2, the vertical division of the rucksack is at the joint of the front body and the gusset, so that by opening and closing the open zipper, the front body can be freely attached and detached from the back body and gusset, or more simply, the front body, which is the front of the rucksack and can be said to be the face of the rucksack (hereinafter referred to as the face), from the rucksack.

[0014] According to the invention of claim 2, the front body, which can be said to be the face of the backpack, can be freely attached and detached from the backpack, so that the removed front body can be turned over and reattached. If the front and back of the front body have different designs, it is possible to enjoy two different designs by turning the front body over.

[0015] According to the invention of claim 2, the front part, which can be considered the lid of the backpack, can be freely removed from the backpack, and when the front part is removed, the inside of the backpack can be seen in detail. Therefore, according to the invention of claim 2, since you can pack your belongings while looking inside the backpack, you can pack your belongings without leaving any gaps and you can also take out only the belongings you need.

[0016] According to the invention of claim 3, the open zipper is a double slider with two sliders attached at the head, so the zipper can be opened and closed at any position around the entire length of the backpack. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] First, we will briefly explain the matters that are the basis of the creation of this invention. The applicant is a bag manufacturer founded in 1983, and has been working to manufacture and develop products by utilizing the thorough quality control of products and production technology know-how incorporating the latest methods that it has cultivated through its long history of working with major apparel companies. In recent years, it has expanded its lineup of fishing-related items such as bags, pouches, leather goods, apparel, and headwear under its original brand "FULLCLIP" (Registration No. 5626030).

[0019] The inventor is mainly involved in planning, manufacturing and selling fishing-related items, and in recent years has also been dealing in outdoor bags and casual bags. As a bag craftsman, the inventor places importance on practicality, and has been particular about "bags that are easy to store the things you need, easy to take out, and easy to put away again." This invention was created based on exactly this particular obsession.

[0020] The inventor, who has always strived to develop products that are easy to store and take out the things one needs, noticed that when using a backpack, one has to feel around to store and take out the things one needs. The inventor then thought that the reason one had to feel around was because the opening of the backpack was narrow, and started working on widening the opening.

[0021] The inventors have developed a backpack with a front opening of 180 degrees by attaching a zipper (not an open zipper) continuously from the bottom of the backpack to the right side, top, left side and bottom, just like the backpack in Patent Document 1, thereby solving the problem with conventional backpacks that the user has to open by feeling around.

[0022] Here, the applicant has the following policy: "We insist on doing all the sewing in Japan. To realize our ideas without compromising and maintain the quality of the product, we absolutely need the delicate and detailed craftsmanship of Japanese craftsmen. We gather the thoughts of each craftsman about the product, refine them, and repeat trial and error in search of the ultimate shape. This accumulation of obvious things is our consistent approach to manufacturing." And the inventor, following this policy, repeated trial and error in search of the ultimate shape for widening the opening of the backpack, discovered that it was possible to attach a zipper around the entire circumference of the backpack, and further, that if the zipper was an open zipper, the front body could be freely attached and detached, which led to the creation of this invention.

[0023] Next, an embodiment of the present invention will be described in detail with reference to the drawings as appropriate. Fig. 1 is a perspective view of a reversible backpack according to an embodiment. As shown in Fig. 1, the reversible backpack 1 is configured to have a back body 3 equipped with shoulder straps 2, 2, a front body 4, and a gusset 5. The reversible backpack 1 according to the embodiment is configured to have an open zipper 6 all around the longitudinal division, here at the joint between the front body 4 and the gusset 5. The longitudinal direction of the backpack refers to the up-down direction when the backpack is worn on the back (the side with the head is on top and the side with the feet is on the bottom).

[0024] The shoulder straps 2, 2 are string-like members that are hung on the left and right shoulders so that the backpack can be carried on the back.

[0025] The back part 3 is the part that touches the back when the backpack is worn, and is also called the back or rear part. Here, the back part is a common term that indicates the main part of a bag or handbag, and refers to the largest main part where luggage is placed.

[0026] The front body 4 is the front part of the backpack and is also called the front or front body.

[0027] The gusset 5 is a portion that extends the width of the bag. Although the back body 3, the front body 4, and the gusset 5 are illustrated in FIG. 1 as if they were separate members, the back body 3, the front body 4, and the gusset 5 indicate these portions and do not have to be separate members.

[0028] The open fastener 6 is a fastener that can be separated into left and right or top and bottom when slid to the end, and is also called an open product. Here, the open fastener 6 has two sliders 61, 61 attached head to head (61a in the enlarged view shows the head side of the slider 61).

[0029] Fig. 2 is an exploded view of the reversible backpack 1 according to the embodiment. As shown in Fig. 2, in the reversible backpack 1 according to the embodiment, when the open fastener 6 is fully opened, the front body 4 can be removed from the back body 3 and the gusset 5.

[0030] FIG. 3 is an enlarged view of a main portion of the reversible backpack 1 according to the embodiment, showing the bottom of the backpack with the open fastener 6 attached.

[0031] As shown in Figure 3, the reversible backpack 1 is configured to have an open zipper 6 that runs all the way around the joint between the front body 4 and the gusset 5. The open zipper 6 is made up of a slider 61, a tooth (element) 62, a tape 63, and an opening device, which in turn is made up of a butterfly pin 64, a box pin 65, and a box 66.

[0032] 3, in the reversible backpack 1 according to the embodiment, when the open fastener 6 is fully opened, specifically by lowering the slider 61 until it touches the box 66 and removing the insert pin 64, the upper and lower tapes 63, 63 separate and the front body 4 can be removed from the gusset 5. Also, in the reversible backpack 1 according to the embodiment, when the open fastener 6 is closed, specifically by lowering the slider 61 until it touches the box 66, inserting the insert pin 64 all the way to the base, and pulling up the slider 61 while holding down the insert pin 64 side, the upper and lower teeth (elements) 62, 62 engage and the front body 4 can be attached to the gusset 5.

[0033] Fig. 4 is an explanatory diagram showing the reversible mechanism of the reversible backpack 1 according to the embodiment. As shown in Fig. 4, in the reversible backpack 1 according to the embodiment, when the open fastener 6 is fully opened, the front body 4 can be removed from the gusset 5, and when the open fastener 6 is closed, the front body 4 can be attached to the gusset 5, so that the removed front body 4 can be turned inside out and reattached.

[0034] Figure 5 is an explanatory diagram of the front body 4 showing the reversible mechanism of the reversible backpack 1 of the embodiment, where (a) of Figure 5 is an explanatory diagram showing the surface of the front body, and (b) of Figure 5 is an explanatory diagram showing the underside of the front body.

[0035] As shown in FIG. 5, the back surface 4' of the front torso has a different design from the front surface 4. In this case, the back surface 4' has a mesh pocket 41, which is useful for storing wet clothes separately.

[0036] In the reversible backpack 1 according to the embodiment, a mesh pocket 41 is provided on the front body (back side) 4'. For example, if the backpack is reattached so that the front body (back side) 4' faces outwards when returning home from club activities, it is possible to prevent the inside of the backpack from smelling of sweat due to wet items such as sweaty gym clothes or towels placed in the mesh pocket 41.

[0037] Fig. 6 is an explanatory diagram showing the state in which luggage is packed into and removed from a reversible backpack 1 according to an embodiment. As shown in Fig. 6, the reversible backpack 1 has an open zipper 6 that runs all the way around the joint between the front body 4 and the gusset 5 in the vertical split direction, so that when the open zipper 6 is opened wide, the front body 4 (front body (reverse) 4' in the figure) opens 180 degrees. Thus, with the reversible backpack 1 according to an embodiment, the front body 4 can be opened 180 degrees, allowing luggage to be packed while looking inside the backpack. Also, when luggage is to be removed, the front body 4 can be opened 180 degrees, allowing the user to look inside the backpack and remove only the necessary luggage.

[0038] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, in the reversible rucksack 1 according to the embodiment, the open zipper 6 is attached to the joint between the front body 4 and the gusset 5. However, as long as it is in the vertical division direction of the rucksack, it may be attached to, for example, the gusset 5 or the front body 4, or it may be attached diagonally in the vertical division direction between the gusset 5 and the front body 4.

[0039] In addition, in the reversible backpack 1 according to the embodiment, the back body 3, front body 4, and gusset 5 have been described as separate components, but the back body 3, front body 4, and gusset 5 indicate those parts and do not have to be separate components.

[0040] In this invention, the vertical direction of the backpack refers to the up-down direction when the backpack is worn (the head side is the top and the feet side is the bottom). [Explanation of symbols]
