technical field

The utility model relates to a suitcase, in particular to a foldable suitcase.

Background technique

When traveling abroad, travelers often need to prepare suitcases to store travel necessities and purchased trophies. Luggage can be divided into boarding box and medium and large luggage according to size. Medium and large suitcases have larger capacities for travelers to carry larger quantities of items. Although a large-capacity suitcase can carry more accompanying items, when the trip is over, the large-capacity suitcase will cause inconvenience in storage. Therefore, in order to take into account both capacity and storage requirements, manufacturers have developed foldable suitcases (such as Taiwan Patent Publication No. M471788). The feature of the foldable suitcase is that the user can unfold the foldable suitcase to load items, or fold the foldable suitcase to reduce its volume for easy storage.

Although the above-mentioned foldable suitcase can meet the needs of both capacity and storage, the convenience of use is still not as good as that of the hard-shell suitcase because the traditional folded suitcase still needs to be unfolded manually. For example, the folded suitcase that has been stored cannot actually return to the unfolded state as expected, but stays in a stacked state or a semi-stacked state. In this way, the user will have to manually pull the foldable suitcase, or even reversely bend the bend of the foldable suitcase to force the foldable suitcase to return to the unfolded state. Therefore, how to make the foldable suitcase automatically return to the unfolded state to improve the convenience of use of the foldable suitcase will be one of the problems that the research and development manufacturers should solve.

Since the flexible deformation capacity of the sugarcane cloth layer, SBR layer and 150D Jiaji cloth layer is greater than that of the 1682D cloth layer, EVA layer and PP board layer of the PU bottom, and the sugarcane cloth layer, SBR layer and 150D Jiaji cloth layer The layer has the property of being bendable, so when these bending parts 320 are bent, the adjacent side wall parts 310 of each bending part 320 can be bent so that these side wall parts 310 can be stacked on the box. Back member 100.

As shown in FIG. 2 , the two reset members 400 are respectively disposed on the inner side of the annular box surface member 300 through two flexible fixing pieces 500 , and the reset members 400 are located on the side of the annular box surface member 300 away from the box back member 100 . The flexible fixing member 500 is, for example, cloth, elastic or nylon. Each flexible fixing member 500 has a fixing section 510 and a suspension section 520 connected thereto. The two fixing sections 510 are disposed on the annular box surface member 300 , and the two suspending sections 520 are respectively connected to opposite ends of the elastic member 600 . The elastic member 600 is, for example, an elastic band. Wherein, the fixing section 510 is, for example, sewn on the annular box surface member 300 , while the suspension section 520 is not fixed on the annular box surface member 300 . The connection of the two suspension sections 520 through the elastic member 600 can reserve space for the elastic deformation of the reset member 400 , and additionally provide a reset elastic force through the elastic member 600 .

For the convenience of assembly, one end of the elastic member 600 in this embodiment is sewn to one of the suspension sections 520 , and the other end is detachably adhered to the other suspension section 520 through Velcro.

In this embodiment, the reset member 400 is disposed inside the annular box surface member 300 , but it is not limited thereto. In other embodiments, the reset member 400 can also be disposed outside the annular box surface member 300 .

In this embodiment, the number of reset members 400 is two, and the two reset members 400 jointly surround the accommodating space 330, but it is not limited thereto. In other embodiments, the number of reset members 400 can also be one , and the single reset member 400 surrounds the accommodating space 330 .

In this embodiment, each reset member 400 spans at least one bending portion 320, and the reset member 400 is elastic, such as a coil spring or an elastic strip, so that the elastic potential energy generated by the lateral bending of the coil spring or It is the elastic potential energy generated by the stretching deformation of the elastic strips that drives the side wall portions 310 that deviate from the erect state to spring back to the erect state.

As shown in Figure 5A, when the ring-shaped box surface member 300 is subjected to an external force and the bending portion 320 is bent relative to the side wall portion 310, the flexible section 322 of the bending portion 320 will form a folding line 322a, and the bending portion 320 will squeeze. Pressing the elastic deformation section 420 of the reset member 400 forces the elastic deformation section 420 to bend laterally, and makes the elastic deformation section 420 store the elastic potential energy of reset to form a reset force F. The extension line of each restoring member 400 intersects with the corresponding folding lines 311 , 321 of the bending portion 320 .

As shown in FIG. 5B , when the external force disappears, the reset force F generated by the elastic deformation section 420 will actively force the bending portion 320 to spring back to its original position along the direction indicated by the arrow D to achieve the reset effect.

The foldable suitcase 10 of this embodiment further includes a first strap 710 and a second strap 720 . The first strap 710 and the second strap 720 are respectively disposed on two opposite side wall portions 310 .

See Figures 6 through 8. 6 and 7 are schematic diagrams of the folding process of the annular box surface member in FIG. 2 . Fig. 8 is a schematic perspective view of the reset of the annular box surface member in Fig. 2 .

As shown in FIG. 6 , the upper and lower side wall portions 310 can be folded inward (in the direction indicated by arrow a). The side wall parts 310 on the upper and lower sides will be bent inwardly relative to the box back member 100 in conjunction with the side wall parts 310 on the left and right sides, and at least one linking section 321 and flexible section 322 of these bending parts 320 will respectively The fold lines 321a, 322a are formed. When the linking section 321 and the flexible section 322 of the bending portion 320 are bent, the elastically deformable section 420 of the reset member 400 is forced to bend laterally and store elastic potential energy for reset.

As shown in Figure 7, the side wall portions 310 on the left and right sides are completely superimposed on the box back member 100 (in the direction indicated by the arrow b), and the first strap 710 is fastened to the second strap 720 , so as to fix each side wall portion 310 in a stacked state.

As shown in FIG. 8 , when the user releases the fastening relationship between the first strap 710 and the second strap 720 , the elastic deformation section 420 of the reset member 400 will release the elastic potential energy to allow each side wall portion 310 to self-fold. The set state springs back to the upright state.

From the above operations, it can be seen that when the user wants to use the suitcase, he only needs to release the buckled first strap 710 and the second strap 720, and the elastic potential energy of the elastic deformation section 420 can be used to force the side wall parts 310 Automatically return to the upright state. Therefore, the user does not need to manually move the side wall portions 310 stuck in the stacked state or semi-stacked state to the upright state, thereby greatly improving the convenience of use of the foldable luggage case 10 .

That is to say, only one flexible fixing piece 500 can be used to surround the reset member 400 on the annular box surface member 300 . Since the reset member 400 is arranged around the annular box surface member 300, a more comprehensive reset effect can be provided.

After the accommodating space 330 is closed, the fluid in the accommodating space 330 can force each side wall portion 310 to slowly return to the upright state.

It is worth noting that the reset member 400 of this embodiment is not limited to be applied to the above-mentioned collapsible luggage case 10, and in other embodiments, the reset member 400 can also be applied to other styles of collapsible luggage cases 10 (such as Taiwan Patent publication number M471788 disclosed suitcase), so that the collapsible suitcase 10 has the effect of automatically springing back from the stacked state to the erected state.

According to the foldable suitcase disclosed in the above embodiments, each side wall part that deviates from the upright state is forced to automatically spring back to the upright state through the elastic deformation characteristic of the reset member. In this way, the user no longer needs to manually move the side walls stuck in the stacked state or half-stacked state to the erected state, thereby greatly improving the convenience of use of the foldable suitcase.

Furthermore, the suspension section of the flexible fixing part is connected by the elastic member, which can not only provide the space required for the deformation of the reset member, but also provide an additional reset effect.
