Description

Folding suitcase

The present invention relates to a luggage case, and more particularly to a folding luggage case. Background technique

When traveling abroad, travelers often need to prepare suitcases to store travel essentials and purchased spoils. The trunk can be divided into a chassis and a medium and large suitcase according to the size. Medium and large suitcases have a large capacity for travelers to carry larger quantities of items. Although a large-capacity suitcase can carry more accompanying items, when the trip ends, the large-capacity suitcase brings inconvenience in storage. Therefore, in order to balance the demand for capacity and storage, manufacturers have developed folding suitcases (such as Taiwan Patent Notice No. M471788). The folding luggage features that the user can unfold the folding luggage to load the items, or fold the folding luggage to reduce the size for storage.

Although the above-mentioned folding suitcase can meet both the capacity and the storage requirements, since the conventional folding folding luggage still needs to be manually deployed, it is still not as convenient to use as the hard-shell luggage. For example, the stored folding suitcase can not be restored to the unfolded state as expected, but stays in a stacked state or a semi-overlapping state. As a result, the user will have to manually pull the folding suitcase, or even bend the fold of the folding suitcase to force the folding suitcase to return to the unfolded state. Therefore, how to make the folding suitcase automatically return to the unfolded state to improve the ease of use of the folding luggage box is one of the problems that the R&D manufacturer should solve.

The folding luggage case 10 of the present embodiment comprises a box back member 100, a box member 200, a ring box member 300, two reset members 400, two flexible members 500 and two elastic members 600.

The opposite sides of the annular box member 300 are coupled to the box back member 100 and the box member 200, respectively, to form an optionally closed receiving space 330. The embodiment is such that one side of the annular box member 300 is sewn to the box back member 100, and the other side of the annular box member 300 is coupled to the case member 200 by a zipper. When the zipper is closed (as shown in Fig. 1), the casing member 200 closes the accommodating space 330, and when the zipper is opened (as shown in Fig. 2), the casing member 200 can be opened to expose the accommodating space 330. However, it is not limited thereto. In other embodiments, the opposite sides of the annular box member 300 may also be coupled to the box back member 100 and the box member 200 by two zippers, respectively.

In addition, the box back member 100 and the box member 200 of the present embodiment are made of a relatively hard material, and the protection is better, for example, polyethylene (PE), polypropylene (PP), polycarbonate (PC). , EVA, PVC or ABS resin (ABS) and other plastic panels. However, it is not limited thereto. In other embodiments, the box back member 100 and the box member 200 may also be made of cloth.

The annular box surface member 300 of the present embodiment is made of a composite material, for example, a hard material such as cloth, PE, PVC, PP, polycarbonate (PC), EVA or ABS, and sugar cane cloth, SBR. , 150D good fabric, PU, rubber, TPU, Sandwich Mesh Fabric, diving cloth, POLY cloth, TPR, ribbon or leather and other soft materials. In detail, the annular box surface member 300 includes a plurality of side wall portions 310 and a plurality of bent portions 320 that engage the side wall portions 310. The bent portions 320 are bendable so that the side wall portions 310 can be stacked or erected relative to the box back member 100. The stacked state of the side wall portions 310 means that the inner wall surface of the side wall portion 310 is stacked on the box back member 100. The upright state of the side wall portions 310 means that the side wall portions 310 are perpendicular or nearly perpendicular to the box back member 100. In other words, in the folding process of the annular box member 300, a portion where the fold line and the bending deformation are generated is defined as the bent portion 320, and a portion where the fold line and the bending deformation are not generated is defined as the side wall portion 310.

Each side wall portion 310 is composed of, for example but not limited to, a 1682D cloth layer, an EVA layer and a PP plate layer of a PU bottom. Each bent portion 320 includes two interlocking segments 321 and a flexible segment 322. The flexible section 322 is connected between the two interlocking sections 321 and the two interlocking sections 321 are respectively connected to the two side wall sections 310. The material of the interlocking section 321 is, for example, the same as that of the side wall portion 310. That is, the interlocking section 321 is composed of, for example but not limited to, a 1682D cloth layer, an EVA layer and a PP board layer of a PU bottom. . The flexible section 322 is composed of, for example but not limited to, a stack of a cane cloth layer, an SBR layer and a 150D good cloth layer, and the flexible deformation capability of the flexible section 322 is greater than the flexible deformation of the interlocking section 321 . ability. Among them, the above-mentioned sugar cane layer is made of, for example, butadiene rubber (SBR). The flexibility deformation ability of the sugarcane fabric layer, the SBR layer and the 150D good fabric layer is greater than the flexibility of the 1682D cloth layer, the EVA layer and the PP layer of the PU bottom layer, and the sugar cane layer, the SBR layer and the 150D good cloth. The layer has a bendable property, so that when the bent portion 320 is bent, the two side wall portions 310 adjacent to each of the bent portions 320 can be bent so that the side wall portions 310 can be stacked on the opposite side of the box. Back member 100.

As shown in Fig. 2, the two return members 400 are respectively disposed on the inner side of the annular box member 300 by the two flexible fixing members 500, and the reset member 400 is located on the side of the annular box member 300 away from the box back member 100. The flexible fastener 500 is, for example, a cloth, an elastic band or a nylon. Each flexible fixture 500 has a fixed section 510 and a suspension section 520 attached thereto. The two fixing sections 510 are disposed on the annular box surface member 300, and the two suspension sections 520 are respectively connected to opposite ends of the elastic member 600. The elastic member 600 is, for example, an elastic band. Here, the fixing section 510 is sewn to the annular box surface member 300, for example, and the suspension section 520 is not fixed to the annular box surface member 300. By engaging the elastic members 600, the two suspension segments 520 can reserve a space for elastic deformation of the return member 400, and additionally provide a resilient force for restoring by the elastic members 600.

For ease of assembly, the elastic member 600 of the present embodiment is stitched to one of the suspension segments 520, and the other end is detachably adhered to the other suspension segment 520 by the devil's felt.

In the present embodiment, the reset member 400 is disposed on the inner side of the annular box member 300, but is not limited thereto. In other embodiments, the reset member 400 may be disposed outside the annular box member 300.

In this embodiment, the number of the reset members 400 is two, and the two reset members 400 are collectively surrounding the accommodating space 330, but not limited thereto. In other embodiments, the number of the reset members 400 may also be One, and a single reset member 400 surrounds the accommodating space 330.

In this embodiment, each of the reset members 400 spans at least one of the bent portions 320, and the reset member 400 has elasticity, such as a coil spring or a resilient strip, to generate elastic potential energy by lateral bending of the coil spring or It is the elastic potential energy generated by the elastic deformation of the elastic strip to drive the side wall portions 310 deviating from the erect state to rebound to the erect state. Wherein, the lateral direction is perpendicular to the extending axial direction of the reset member 400.

Further, the reset member 400 of the present embodiment employs a coil spring and the shape of the reset member 400 is a cylindrical shape. The two reset members 400 each include two connecting sections 410 and an elastically deformable section 420. The two connecting sections 410 are respectively connected to opposite sides of the elastic deformation section 420. The two connecting sections 410 are respectively disposed on the different two side wall portions 310, and the elastic deformation section 420 spans at least one of the bending portions 320.

The reset member 400 of the present embodiment is cylindrical so that the upper lateral bending of the return member 400 in all directions can produce the same elastic potential energy to provide a more stable reset effect.

Next, the reset principle of the reset member 400 will be described. The elastically deformable section 420 of the reset member 400 is elastically deformed. Elastic deformation means that when the elastic body is deformed by an external force, if the external force value is within the elastic limit, the deformation of the elastic body is restored after the external force is removed. This embodiment utilizes the elastic deformation characteristics of the elastic deformation section 420 to force the side wall portions 310 to substantially return to the erected state.

Please refer to Figures 5A to 5B. Figure 5A is a cross-sectional schematic view showing the force deformation of the annular box face member of Figure 3. Figure 5B is a cross-sectional view showing the reset of the annular box face member of Figure 3.

As shown in FIG. 5A, when the annular box member 300 is subjected to an external force to bend the bent portion 320 relative to the side wall portion 310, the flexible portion 322 of the bent portion 320 forms a fold line 322a, and the bent portion 320 is squeezed. The elastic deformation section 420 of the pressure reducing member 400 forces the elastic deformation section 420 to laterally bend, and causes the elastic deformation section 420 to store the reset elastic potential energy to form a restoring force F. The extension lines of each of the return members 400 intersect the fold lines 311, 321 of the corresponding bent portions 320, respectively.

As shown in Fig. 5B, when the external force disappears, the restoring force F formed by the elastic deformation section 420 actively forces the bending portion 320 to spring back to the original position in the direction indicated by the arrow D to achieve the reset effect.

The folding luggage case 10 of the present embodiment further includes a first belt 710 and a second belt 720. The first strap 710 and the second strap 720 are respectively disposed on the opposite side wall portions 310.

Please refer to Figure 6 to Figure 8. 6 and 7 are schematic views showing the process of folding the annular box face member of Fig. 2. Figure 8 is a perspective view showing the reset of the annular box face member of Figure 2;

As shown in Fig. 6, the side wall portions 310 on the upper and lower sides may be first folded inward (in the direction indicated by the arrow a:). The side wall portions 310 on the upper and lower sides interlock the side wall portions 310 on the left and right sides with respect to the box back member 100. The inward bending is performed, and the fold lines 321a, 322a are formed on each of the at least one interlocking section 321 and the flexible section 322 of the bent portions 320. When the interlocking section 321 of the bent portion 320 and the flexible section 322 are bent, the elastic deformation section 420 of the returning member 400 is forced to laterally bend and store the elastic potential energy for resetting.

As shown in FIG. 7, the left and right side wall portions 310 are completely superposed on the box back member 100 (in the direction indicated by the arrow b), and the first belt 710 is fastened to the second belt 720. To fix each of the side wall portions 310 to the stacked state.

As shown in FIG. 8, when the user releases the snap-fit relationship between the first strap 710 and the second strap 720, the elastic deformation section 420 of the reset member 400 releases the elastic potential energy to allow the side wall portions 310 to be self-stacked. Set the state back to the erect state.

As can be seen from the above operation, when the user wants to use the trunk, only the first strap of the buckle needs to be released.

710 and the second strap 720, that is, the elastic potential energy of the elastic deformation section 420 can be used to force the side wall portions 310 to automatically return to the erect state. Therefore, the user does not need to manually pull the side wall portions 310 stuck in the stacked state or the semi-stacked state to the erect state, thereby greatly improving the usability of the folding luggage case 10.

See Figure 9. Figure 9 is a cross-sectional view of the annular box face member disclosed in the second embodiment. This embodiment is similar to the embodiment of Fig. 3 described above, and therefore only the differences will be described.

The difference between this embodiment and the above embodiment of Fig. 3 is that the flexible fixing member 500 of the present embodiment has elasticity, for example, an elastic band, so that it is no longer necessary to engage by the elastic force member 600. That is, the reset member 400 can be circumferentially disposed on the annular box member 300 by only one flexible fixing member 500. Since the reset member 400 is circumferentially disposed on the annular box member 300, a more comprehensive reset effect can be provided.

See Figure 10. Figure 10 is a cross-sectional view showing the annular box face member disclosed in the third embodiment. This embodiment is similar to the embodiment of Fig. 3 described above, and therefore only the differences will be described.

The difference between this embodiment and the above embodiment of Fig. 3 is that the folding luggage case 10 of the present embodiment further comprises a flexible cover film 800. The flexible cover film 800 of the present embodiment is coupled to the annular box member 300 by a zipper, and closes the accommodating space 330. After the accommodating space 330 is closed, the fluid in the accommodating space 330 can force the side wall portions 310 to slowly return to the erect state.

It should be noted that the reset member 400 of the present embodiment is not limited to the above-mentioned folding luggage case 10. In other embodiments, the reset member 400 can also be applied to the folding luggage case 10 of other aspects (such as Taiwan). The luggage disclosed in Patent Publication No. M471788:), so that the folding luggage case 10 has an effect of automatically rebounding from the stacked state to the erect state. According to the folding luggage case disclosed in the above embodiment, the side wall portions deviating from the erect state are automatically rebounded to the erect state by the elastic deformation characteristic of the reset member. In this way, the user does not need to manually pull the side wall portions of the card in the stacked state or the semi-stack shape to the erect state, thereby greatly improving the convenience of use of the folding luggage case.

Furthermore, the suspension section of the flexible fastener is engaged by the resilient member, which provides an additional reset effect in addition to providing the space required for the deformation of the reset member.

The invention may, of course, be embodied in various other embodiments and various modifications and changes can be made in accordance with the present invention without departing from the spirit and scope of the invention. Changes and modifications are intended to be included within the scope of the appended claims. Industrial applicability
