Description

Technical Field

[0001] The utility model relates to the field of luggage, in particular to a luggage case with a variable internal space and capable of being folded and compressed. Background Art

[0002] As people's living conditions gradually improve, the requirements for luggage and other consumer goods are also increasing. Now there is a kind of suitcase with compressible side space on the market, which can be folded and stored when not in use, effectively reducing the space it occupies, and the folded suitcase is more convenient to carry. For example, the Chinese utility model patent with patent number: 201921259874.3 discloses a suitcase, which includes a rigid front shell and a rear shell, and a flexible peripheral closed annular side wall is connected between the front shell and the rear shell; the rear shell is smaller than the front shell, so that the rear shell can be included in the front shell, and the inner side of the rear shell is hinged with a rigid support plate, and the other parts of the support plate are detachably attached to the inner wall surface of the flexible peripheral closed annular side wall to play a role in expansion. When the support plate is detached from the flexible peripheral closed annular side wall, the flexible peripheral closed annular side wall of the box body can be folded and stored, and the rear shell can be as close to the inner side of the front shell as possible to achieve a folding effect. However, this type of suitcase still has some shortcomings. For example, the support plate is detachably attached to the flexible peripheral closed annular side wall, so each time it is folded or expanded, it needs to be disassembled or attached back and forth, which is inconvenient to operate. Moreover, when it is expanded, the box body moves in a bumpy manner, and the parts at the attachment point are also easily damaged. Secondly, because the support plate is connected to the rear shell and the flexible peripheral closed annular side wall, the connection rigidity between the rear shell and the front shell is not strong, which makes the overall stability of the box body poor. Although it can achieve 100% expansion in theory, in actual use, the expansion effect is poor due to the weak rigidity. Summary of the invention

[0025] Below, combined with the attached Figure 1-7 And specific implementation methods, the utility model is further described:

[0026] The utility model embodiment discloses a foldable and compressed suitcase, comprising a rigid first shell 1 and a second shell 3, wherein a ring-shaped flexible side wall surface 2 is connected between the first shell 1 and the second shell 3 by means of fixing methods such as sewing, riveting, or zipper closure. The opening of a conventional suitcase is generally arranged on the front end surface of the first shell or the second shell, and can also be arranged between the side wall surface and the first shell or the second shell. The case opening of this embodiment is closed by a zipper 5, and the two tooth chain belts of the zipper 5 are respectively arranged on one end of the side wall surface 2 and the second shell 3. The other end of the side wall surface 2 is sewn and fixed to the first shell 1. This embodiment also includes a foldable part 4 arranged on the inner side of the side wall surface 2; one end of the foldable part 4 is connected to the first shell 1, and the other end is connected to one end of the side wall surface 2 close to the second shell; the foldable part 4 is spliced ​​by a plurality of rigid connecting pieces; the rigid connecting pieces are hinged by a hinge 6 to form a one-piece foldable part 4. The connecting piece can rotate around the hinge 40, so that the front and rear ends of the foldable part 4 can be close to each other; and the foldable part 4 and the side wall surface 2 after rotation can be folded and accommodated in the internal space composed of the first shell 1 and the second shell 3; the connecting piece is also provided with a limiting portion 7, and the limiting portion 7 makes the connecting pieces on the left and right sides of the hinge 6 rotate around the hinge 6. The angle is between 0-180°, that is, the foldable part 4 can only be folded and unfolded in one direction in the suitcase. When the angle approaches 0°, the connecting pieces on the left and right sides of the hinge 6 gradually approach each other and enter a folding state; when the angle is 180°, the connecting pieces on the left and right sides of the hinge 6 are fully unfolded and assembled into a plate-like structure. Blocked by the limiting portion 7, the connecting pieces on the left and right sides of the hinge 6 cannot continue to rotate beyond 180° after being fully unfolded.

[0027] Furthermore, the present embodiment discloses a specific hinged portion 4, including that among the two adjacent connecting plates, at least one rotating cylinder 61 is provided on one side of the front connecting plate; the rear connecting plate is also provided with a rotating cylinder 61 on the side opposite to the front connecting plate, and when the front connecting plate and the rear connecting plate rotate and cooperate, the rotating cylinders 61 on the opposite sides of the front connecting plate and the rear connecting plate can be on the same axial line; there is a rotating shaft 62 passing through the rotating cylinder 61 on the axial line.

[0028] Of course, in some embodiments, there is another hinged portion, including that in the adjacent connecting pieces, at least one rotating drum is provided on one side of the front connecting piece, and a rotating shaft that can be rotatably inserted into the rotating drum is formed on the opposite side of the rear connecting piece.

[0029] Furthermore, this embodiment discloses a specific structure of the position-limiting portion 7, including a front stopper 71 provided on the end surface of the rotating cylinder 61 of the front connecting piece along the axis direction; a rear stopper 72 is provided on the end surface of the rotating shaft 61 of the rear connecting piece along the axis direction to cooperate with the front stopper 71. When the adjacent connecting pieces are in a folded state, the rear end of the front stopper 71 conflicts with the front end of the rear stopper 72; when the adjacent connecting pieces are in an unfolded state, the front end of the front stopper 71 conflicts with the rear end of the rear stopper 72.

[0030] Furthermore, in order to make the foldable sheet 4 more concealed and beautiful inside the suitcase, a protective cloth layer can be set on the outside of the foldable sheet, or the side wall surface can be set as multiple layers of cloth, and the foldable sheet can be hidden in the multiple layers of cloth. The technical solution adopted in this embodiment is to cover the outer surface of the foldable sheet 4 with a protective cloth layer 8 in a fixed form such as sewing or adding a sleeve.

[0031] Furthermore, the foldable sheet 4 is symmetrically arranged in the suitcase, and can be arranged on the left and right sides or the upper and lower sides of the side wall of the suitcase alone, or can be arranged on the upper and lower sides. The foldable sheet 4 is used to support the flexible side wall surface and play a role in expanding the capacity.

[0032] Furthermore, the connecting piece is divided into an end connecting piece 41 close to the first shell 1 or the second shell 3 according to the different positions in the foldable member 4; and an intermediate connecting piece 42 located between the end connecting pieces 41. Of course, in some embodiments, the foldable member 4 may only include two symmetrically distributed end connecting pieces 41. When the number of connecting pieces in the foldable member exceeds three, at least one intermediate connecting piece 42 is included. One end of the end connecting piece 41 is provided with a plate-shaped extension portion 410 with a thickness less than that of other parts, and the extension portion 410 is connected to the first shell 1 and the side wall surface 2 by sewing, hot pressing, riveting or gluing. The extension portion 410 is in the form of a sheet and has a relatively thin thickness, which is convenient for processing and fixing with the first shell 1 and the flexible side wall surface 410. One end of the intermediate connecting piece 42 is provided with a bending portion 420 bent upward along the width direction; the rotating cylinder 61 is arranged at a position tangent to the intermediate connecting piece 42; the intermediate connecting piece 42 forms a "~" shape with the rotating cylinders 61 at both ends. Furthermore, the bending portion 420 makes the axis of the rotating cylinder 61 at the end of the bending portion located in the width direction of the connecting piece. As shown in the drawings of the specification, the foldable member including such an intermediate connecting piece 42 is flat as a whole in the unfolded state, is easy to process, and is evenly stressed.

[0033] Furthermore, a storage zipper 9 is provided on the outer side wall of the side wall surface 3 to store the side wall surface so that the front and rear end surfaces of the side wall surface are close to each other; the storage zipper includes a matching upper toothed chain belt 91, a lower toothed chain belt 92 and a zipper head 93; the upper toothed chain belt 91 and the lower toothed chain belt 92 start from the middle of the outer side wall of the side wall surface 3, extend to the front and rear end of the outer side wall of the side wall surface 3 in a herringbone bifurcation, and surround the front and rear end. When the zipper head 93 of the storage zipper starts to run and close from the starting position until it reaches the end point, most of the side wall surface 3 is stored inside the suitcase, and because the upper zipper 91 is located on the inner side of the suitcase opening zipper 5, this storage does not affect the normal use of the suitcase opening of this embodiment.

[0034] Furthermore, conventional handles are fixed on the flexible side wall surface. This embodiment discloses a way of setting the handle, that is, the connecting piece is close to the inner side of the side wall surface, and a handle is fixed by rivets, gluing or sewing. A handle hole for the handle to extend out is provided at the corresponding position of the side wall surface, and the user can lift the suitcase by hand by holding the handle. Compared with sewing the handle on the side wall surface, this connection method has stronger connection strength and is more durable.

[0035] like Figure 7 As shown, the utility model discloses another embodiment of a foldable and compressible suitcase, wherein the extension portion of one end of the foldable member 4' is connected to the first shell, and the other end is connected to the second shell 3'. The opening of the suitcase of this embodiment is opened on the front end surface of the first shell. As shown in the figure, this embodiment shows the state where the foldable member 4' is not provided with a protective cloth layer 8' and the state where the foldable member 4' is provided with a protective cloth layer 8'.

[0036] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
