Description

[Technical Field]

[0001] The present invention relates to a carry bag that includes a first storage compartment and a second storage compartment, and the second storage compartment is foldable. Note that the term "carry bag" refers to both large bags with and without casters. [Background technology]

[0002] A large bag that can store and transport a lot of luggage is called a carry bag and is in practical use. There are also known variable volume bags whose volume, equivalent to the storage volume, can be changed. Therefore, variable volume carry bags, which combine both, are now in practical use.

[0003] As a technology similar to that of variable-volume carry bags, a waist pouch that can be converted into a backpack has been proposed (see, for example, Patent Document 1 (FIG. 5)).

[0004] Patent Document 1 will be explained with reference to the following figure. 10(a) to 10(c) are diagrams illustrating a waist pouch that can be converted into a conventional backpack.

[0005] As shown in Figure 10(a), the backpack 100 is made up of a first storage compartment 101 at the bottom and a second storage compartment 102 at the top. The second storage compartment 102 at the top is made up of a back panel 103 that contacts the user's back and a bag 104 that makes up the rest of the bag.

[0006] When there is only a small amount of luggage, the upper second storage compartment 102 is folded up, as shown in Figure 10(b). That is, the bag 104 is folded up small and pushed under the back panel 103.

[0007] As shown in Fig. 10(c), the second storage compartment 102 is folded onto the top of the first storage compartment 101. The first storage compartment 101 is used as a waist pouch. That is, according to the cited document 1, the backpack can be converted into a waist pouch, and vice versa, which has the advantage of increasing convenience.

[0008] However, there are some points that need improvement in the technology of Patent Document 1. The points that need improvement will be described below. Second storage chamber 102 is mostly made up of bag 104, which is highly flexible. Therefore, in Figure 10(a), when second storage chamber 102 is empty, second storage chamber 102 is in a so-called "flat" state, making it difficult to put luggage into second storage chamber 102.

[0009] Furthermore, if the amount of luggage is reduced to about half, the bulge of the second storage compartment 102 will be reduced by half, and the shape as shown in FIG. 10(a) will not be achieved, resulting in a poor appearance.

[0010] That is, the technology of Patent Document 1 requires improvement in terms of the difficulty of putting luggage in and the appearance. [Prior art documents] [Patent documents]

[0025] An embodiment of the present invention will be described below with reference to the accompanying drawings. [Example]

[0026] As shown in FIG. 1, the carry bag 10 is a two-compartment bag 10A that includes a first storage compartment 20 for storing luggage and a second storage compartment 40 that is provided above the first storage compartment 20 and also for storing luggage.

[0027] The first storage room 20 is composed of a first bottom 22 equipped with casters 70 and brackets 21, a first front wall 23, a first left side wall 24, a first right side wall (Figure 2, symbol 25), and a first rear wall 26 standing up from the first bottom 22, and a first ceiling 27.

[0028] The first bottom portion 22, the first front wall 23, the first left side wall 24, and the first right side wall (FIG. 2, reference numeral 25) are made of hard walls with little flexibility. The first ceiling 27 may be either a hard wall or a soft wall.

[0029] Hard walls are made of resin boards or woven fabric made from thick threads (including resin threads), and are strong enough that they will not dent even if an object hits them from the outside. A hard wall is a wall that is thicker and less flexible than the soft wall described below.

[0030] A soft wall is a woven fabric made from thin threads (including resin threads), and is a wall that is weak like a membrane and easily deforms when subjected to external forces. The soft wall is a wall that is thinner and more flexible than the hard wall described above.

[0031] The second storage room 40 is composed of a second front wall 41 extending upward from the first front wall 23, a second left side wall 42 extending upward from the first left side wall 24, a second right side wall (Figure 2, symbol 43) extending upward from the first right side wall (Figure 2, symbol 25), a second rear wall 44 extending from the first rear wall 26 to a position slightly higher than the second front wall 41, and a second ceiling 45 covering the upper surface.

[0032] The floor of the second storage room 40 is the first ceiling 27, and is therefore excluded from the components of the second storage room 40.

[0033] The second front wall 41 is formed of a hard wall and is connected to the first front wall 23 via a horizontal valley fold line 46 (extending in the front-to-rear direction in the drawing). The second rear wall 44 is made of a hard wall and is connected to the first rear wall 26 via a horizontal valley fold line 46. The second rear wall 44 is provided with a secondary handle 47.

[0034] The second left wall 42 and the second right wall 43 are made of soft walls that are highly flexible. The second ceiling 45 may be either a hard wall or a soft wall, but is preferably a semi-hard wall with hardness (or rigidity) intermediate between a hard wall and a soft wall, since the main handle 48 is attached to it. The semi-hard wall is made by, for example, stacking multiple layers of woven fabric made of thin threads, or by placing a core material between two layers of woven fabric made of thin threads.

[0035] The cross section of the second storage room 40 is U-shaped (gate-shaped) consisting of a second front wall 41 made of a hard wall, a second ceiling 45 made of a soft wall, hard wall or semi-hard wall, and a second back wall 44 made of a hard wall.

[0036] The second front wall 41 is connected to the first front wall 23 via a valley fold line 46. The valley fold line 46 formed in the hard wall has a small but effective effect of preventing folding. Therefore, the second front wall 41 will stand on its own unless a horizontal force is applied from the outside. The second rear wall 44 is also freestanding.

[0037] In addition, the second ceiling 45 serves as a bridge connecting the upper end of the second front wall 41 and the upper end of the second rear wall 44. The second ceiling 45 reinforces the second front wall 41 and the second rear wall 44 to prevent them from collapsing. As a result, although the second storage chamber 40 has a lower shape retention than the first storage chamber 20, it still maintains its box-like shape even when empty.

[0038] The first ceiling 27 preferably has a window portion 28 that corresponds to a ceiling window. When the fastener 28a is opened, most of it falls down and runs along the first rear wall 26, as shown by the imaginary lines. This connects the first storage compartment 20 and the second storage compartment 40, turning the two compartments into one. This is convenient when storing large items whose height exceeds the height of the first storage compartment 20.

[0039] When the fastener 29a is opened, the first door 29 opens. When the fastener 49a is opened, the second door 49 opens.

[0040] In this embodiment, the first bottom 22 is provided with a bracket 21, and the bracket 21 is provided with a caster 70, but the caster 70 and bracket 21 may be omitted by providing a leg member on the first bottom 22.

[0041] 2, by opening the first door 29, luggage can be put in and taken out of the first storage compartment 20. Similarly, by opening the second door 49, luggage can be put in and taken out of the second storage compartment 40.

[0042] At this time, the first storage chamber 20 and the second storage chamber 40 maintain their box-like shape, and have a good appearance. Furthermore, since the first storage compartment 20 and the second storage compartment 40 maintain their box-like shapes, it is extremely easy to put in and take out luggage. Therefore, this embodiment provides a carry bag 10 that is easy to put luggage in and has a good appearance.

[0043] As shown in Fig. 3, a lower zipper half 51 is provided on the upper edge of the first storage chamber 20, and an upper zipper half 52 is provided on the second rear wall 44. In Fig. 5 described below, the lower zipper half 51 is engaged with the upper zipper half 52.

[0044] A large pocket 53 that can be opened and closed with a zipper 53a is provided on the first right wall 25, and a waterproof bag 54 made of resin is stored inside this pocket 53.

[0045] Next, the procedure for rearranging a two-room configuration into a one-room configuration will be described with reference to FIGS. 4(a) to 4(d). FIG. 4(a) corresponds to a drawing in which the main part of FIG. 1 is excerpted. In FIG. 4(a), the second front wall 41 is folded and placed on the first ceiling 27 as indicated by the arrow (1). As shown in FIG. 4(b), the second front wall 41 rests on the first ceiling 27, and the upright second rear wall 44, the hanging second ceiling 45, and the triangular second left wall 42 are visible.

[0046] FIG. 4(c) is a view taken along the arrow c in FIG. 4(b), and the second ceiling 45 can be seen in the background, and the second left wall 42 and the second right wall 43 can be seen on the left and right sides of the second ceiling 45. As shown by the arrow (2), the second left wall 42 and the second right wall 43 are moved inward, and the second rear wall 44 is folded down as shown by the arrow (3) in FIG. 4(b).

[0047] As a result, as shown in FIG. 4(d), the second rear wall 44 is placed on top. That is, the second left wall 42, the second right wall 43 and the second ceiling 45 were stacked on top of the second front wall 41, and the second rear wall 44 was folded and stacked on top of the second front wall 41, the second left wall 42, the second right wall 43 and the second ceiling 45.

[0048] If the user neglects to push the second left wall 42 and the second right wall 43 together as indicated by the arrow (2) in Fig. 4(c), both (or one) of the second left wall 42 and the second right wall 43 will protrude, making it impossible to achieve the configuration shown in Fig. 4(d). In this case, simply go back to Figure 4(c) and proceed in the order of Figure 4(c) → Figure 4(b) → Figure 4(d). In other words, the folding procedure shown in Figures 4(a) to (d) can be easily achieved by users of all levels of proficiency.

[0049] As a result of the above, the carry bag 10 as shown in FIG. 5 has been remodeled into a single-compartment bag 10B. The size of the single-compartment bag 10B shown in FIG. 5 is, for example, 430 mm in length, 350 mm in width, and 200 mm in depth (dimensions from front to back in the drawing). When the single-compartment bag 10B is folded forward, its dimensions change to 200mm x 350mm x 430mm in height, width and depth.

[0050] In contrast, the dimensions of a standard coin locker are (257mm~404mm) x 355mm x 570mm in height, width and depth. Therefore, the single-compartment bag 10B can be easily stored in a standard coin locker.

[0051] That is, when the two-compartment bag 10A shown in Fig. 1 does not fit into the coin locker, the luggage in the second storage compartment 40 is transferred to an appropriate "other bag." The second storage compartment 40 is folded using the procedure shown in Fig. 4. The single-compartment bag 10B shown in Fig. 5 and the "other bag" are placed into the coin locker.

[0052] When returning the bag, the user takes out the single-compartment bag 10B and the "other bag" from the coin locker. The second storage compartment 40 is expanded. The baggage from the "other bag" is transferred to the second storage compartment 40. The bag can now be returned to the single-compartment bag 10B shown in FIG. 1.

[0053] Although not mentioned above, the carry bag 10 of the present invention is equipped with a carry handle. 6, a carry handle 60, shown by a dashed line, is stored in the first rear wall 26. A hollow guide 61 is fixed to the first rear wall 26, and a telescopic multi-stage barrel 62 is stored in this guide 61, with a grip 63 spanning the upper end of the multi-stage barrel 62.

[0054] The user opens the zipper 56a, flips up the lid 56, and pulls out the carry handle 60 as shown by the two-dot chain line. The user can use the carry handle 60 to easily move the carry bag 10 (single-compartment bag 10B) sideways along the floor or road surface.

[0055] The same applies to the carry bag 10 (two-compartment bag 10A) shown in Fig. 1. At this time, the multi-stage cylinder 62 that constitutes the carry handle 60 extends upward while making close contact with the second rear wall 44 shown in Fig. 1. In FIG. 1, the second rear wall 44 is prevented from tipping over by the carry handle (FIG. 6, reference numeral 60), particularly the multi-stage cylinder, so that the second storage chamber 40 can more preferably maintain its box-like shape.

[0056] 6, when the carry handle 60, particularly the grip 63, is stowed, it becomes invisible, improving the appearance. In addition, cushioning material is built into the first rear wall 26 and the lid 56, so that when the user carries the bag, the carry handle 60, particularly the grip 63, will not come into contact with the user's back. The cushioning material may be either cotton or sponge.

[0057] Next, the procedure for carrying the carry bag 10 on your back will be described. As shown in Figure 7(a), a lower belt hook 65 is provided at the bottom of the first rear wall 26, and an upper belt hook 66 is provided at the top of the second rear wall 44, so that in the carry bag 10, a shoulder belt 68 can be hung between the lower belt hook 65 and the upper belt hook 66. By incorporating cushioning material in the second rear wall 44 as well, the burden on the back is reduced.

[0058] Furthermore, as shown in Figure 7(b), an intermediate belt hook 67 is provided at the top of the first rear wall 26, so that in the single-compartment bag 10B, a shortened shoulder belt 68 can be hung between the lower belt hook 65 and the intermediate belt hook 67.

[0059] According to the user's preference, the shoulder strap 68 can be hung between the lower belt hook 65 and the middle belt hook 67 in FIG. 7(a). That is, since the carry bag 10 of the present invention is equipped with a lower belt hook 65, an upper belt hook 66, and an intermediate belt hook 67, the user can freely select between the combination of the lower belt hook 65 and the upper belt hook 66 and the combination of the lower belt hook 65 and the intermediate belt hook 67, thereby increasing convenience.

[0060] Preferably, the caster 70 is removed from the bracket 21 and stored in the waterproof bag 54 inside the pocket 53. Since the caster 70 is stored in the waterproof bag 54, it does not matter if the caster 70 is dirty with mud or rainwater, because the waterproof bag 54 can be removed and washed as needed. To achieve this, the casters 70 must be designed to be detachable. An example of such a structure will now be described.

[0061] As shown in Figure 8(a), the caster 70 consists of a caster shaft 71 inserted from below into the bracket 21 fixed to the first bottom 22, a fork member 72 extending downward from the caster shaft 71 and splitting into two, and a wheel 73 attached to the fork member 72.

[0062] The bracket 21 is equipped with, for example, an S-shaped member 74, a pin 75 that secures the S-shaped member 74 to the bracket 21 so that it can rotate freely, a leaf spring 76 that urges the lower part of the S-shaped member 74 toward the caster shaft 71, and an unlock button 77 that presses the S-shaped member 74 in the opposite direction to urging the leaf spring 76 (the direction to release the lock). The caster shaft 71 has an annular groove 78. The S-shaped member 74 has a pointed claw 79 and an inclined surface 81 at the bottom.

[0063] 8(a), the claws 79 enter the annular grooves 78, restricting axial movement of the caster shaft 71 but allowing rotation of the caster shaft 71. Therefore, the wheels 73 roll on the floor or road surface, and the fork members 72 rotate around the caster shaft 71.

[0064] When the unlock button 77 is pressed, the claw 79 moves away from the annular groove 78. Thereafter, the caster shaft 71 can be pulled downward from the bracket 21.

[0065] When the removed caster shaft 71 is inserted into the bracket 21, the tip of the caster shaft 71 presses against the inclined surface 81. When the caster shaft 71 is further raised, the claw 79 fits into the annular groove 78, returning to the state shown in FIG. 8(a). As described above, the caster shaft 71 is detachably inserted into the bracket 21.

[0066] The configuration of the S-shaped member 74 and the leaf spring 76 is merely an example and may be changed as appropriate. The point is that the caster shaft 71 may be configured to be detachably inserted into the bracket 21, and the configuration is not limited to that of the embodiment.

[0067] 8(b), when it is not necessary to make the caster axle 71 detachable, a structure can be adopted in which the tip of a setscrew 83 is simply fitted into the annular groove 78. The setscrew 83 prevents the caster axle 71 from moving in the axial direction while allowing it to rotate. Preferably, a resistance member 84 is provided between the caster shaft 71 and the bracket 21.

[0068] An O-ring is suitable for the resistance member 84. The crushing allowance of the O-ring is determined in consideration of the force (resistance force) described below. As shown in Figure 8(c), when the caster shaft 71 is horizontal, the weight of the wheel 73 causes the fork member 72 to rotate around the caster shaft 71. A resistance force large enough to suppress this rotation is generated by the resistance member 84. The resistance force is limited to a level that allows the caster shaft 71 to rotate when the wheel 73 travels on a floor or road surface.

[0069] Some users find it troublesome to attach and detach the casters 70, and may carry the carry bag 10 on their back with the casters 70 still attached. In this case, the structure shown in FIG. 8(b) described above is useful.

[0070] 9, the user turns the wheels 73 inward with their hands. If the user carries the stroller in this state, the wheels 73 will not come into contact with the user's back. The wheels 73 will also prevent the user's back from getting dirty. The resistance action of the resistance member (FIG. 8(b), reference numeral 84) suppresses rotation (idling) of the caster shaft, and the fork member 72 will not rotate on its own when the bag is carried on the back and moved.

[0071] Although the structures in FIG. 8(a) and FIG. 8(b) are independent of each other, there is no problem in adding a resistance member 84 to the structure in FIG. 8(a). Therefore, the structure of the caster 70 can be set arbitrarily.

[0072] Furthermore, the carry bag 10 of the present invention is not limited to a bag in the strict sense, but may be a carry case, a suitcase with wheels, a trunk with wheels, a bag with wheels, or any of the like.

[0073] In addition, in the embodiment, the carry bag 10 comprises a first storage compartment 20 and a second storage compartment 40 above it, but the present invention is not limited to a two-compartment bag. That is, the first storage chamber 20 may be made up of three or more chambers arranged vertically. In this case, the uppermost chamber is the second storage chamber 40, and the chamber below that is the first storage chamber 20.
