Description

Technical Field

[0001] The present invention relates to the technical field of suitcases, and more particularly to a suitcase provided with a hard frame on a front cover having a front cover on one side of the suitcase body and having a hard frame and a lock facing each other between the front cover and the suitcase body.

Background Art

[0002] The configuration of a general suitcase includes a front suitcase body and a rear suitcase body. The volumes of the two suitcase bodies are quite large, and between the two suitcase bodies, opposing frames are arranged, and a lock is attached to one of the frames and used to lock the other frame. By doing so, when the two mating suitcase bodies are unfolded and laid flat on a predetermined plane with the opening facing upward, the items inside the suitcase can be taken out. Similarly, when storing items, it is also necessary to lay the suitcase flat and unfold it.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Such a suitcase has the advantages of having suitable structural strength and being difficult to be opened by malicious persons. However, because the volumes of the two suitcase bodies are quite large, it is necessary to lay the suitcase flat to take in and out items. Otherwise, if the suitcase is opened in a standing state, the items inside the case will scatter, which is a drawback.

[0004] Other common suitcases have a front cover located on one side of the large suitcase body. The large suitcase body can be separated into two parts, and these two parts are joined together by a zipper. The front cover is also connected to the suitcase body by a zipper. This structure allows the suitcase to be laid flat as needed, and items can be put in and taken out by opening the zipper between the two parts of the suitcase body. Even when the suitcase is upright, items can be put in and taken out by opening the zipper between the front cover and the suitcase body. While this type of suitcase offers good convenience, it has the drawback that the zipper can be easily opened by malicious actors, as inserting just one item into the interlocking part can break the interlocking mechanism, resulting in low security.

[0005] Therefore, the inventor believed that the above-mentioned shortcomings could be improved, and after diligent consideration, arrived at the proposal of this invention, which effectively improves the above-mentioned problems through a rational design.

[0006] This invention was made in view of the above problems and aims to provide a suitcase equipped with a hard frame on the front cover. Specifically, the connection between the front cover and the suitcase body of this invention employs a connection structure of a rigid front cover frame and a rigid suitcase frame, modifying the conventional zipper structure between the front cover and the suitcase body. Furthermore, the front cover frame and the suitcase frame are hidden within the concave ring portion of the suitcase body, making it difficult to forcibly open the front cover frame and enhancing the suitcase's security. In addition, the lock plate of the lock penetrates the frame of the suitcase frame and is coupled to the lock mounting portion of the lock, thereby increasing the connection strength between the lock and the suitcase body. [Means for solving the problem]

[0007] To achieve the above objective, one aspect of the present invention provides a suitcase comprising a suitcase body, a suitcase frame, a front cover, a front cover frame, and a lock. The suitcase body has an internal storage space, one side of which is an opening, and the mounting area is formed on the other side of the suitcase body and is adjacent to the opening. The suitcase frame consists of at least one rigid frame and is attached to the periphery of the opening, with a portion of the suitcase frame adjacent to and having a through hole through the mounting area. The front cover is rotatably positioned on one side of the suitcase body and is used to cover the opening. The front cover frame consists of at least one rigid frame and is attached to one side of the front cover. The lock includes an operating section, a lock mounting section, and at least one lock plate. The lock mounting section is connected to the operating section, penetrates the mounting area, and is located on one side of the through-hole in the suitcase frame. The operating section is exposed to the mounting area, and the lock plate is attached to the front cover frame. The front cover and front cover frame combine to cover the opening, and the lock plate passes through the through hole and the lock mounting area, thus forming a connection.

[0010] The embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the embodiments described below, and can take various forms as long as they fall within the technical scope of the present invention.

[0011] (First embodiment) Figure 1 is an external perspective view showing a suitcase 100 according to a first embodiment of the present invention. The suitcase 100 comprises a suitcase body 110 and a front cover 120. As is commonly understood in construction, the suitcase body 110 has a storage space 111 for storing items, and the storage space 111 has an opening on one side facing the front of the suitcase body 110. The front cover 120 is positioned on the front of the suitcase body 110 and has a volume smaller than the volume of the suitcase body 110. Because of the small volume of the front cover 120, it mainly functions to seal the opening of the storage space 111 of the suitcase body 110. When the front cover 120 is open, the storage space 111 is exposed so that the user can put items in and take them out. With the front cover 120 covering the storage space 111 of the suitcase body 110, at least one lock 130 allows the front cover 120 to be positioned on the front of the suitcase body 110.

[0012] Furthermore, the telescopic rod 140 is arranged on the back of the suitcase body 110 or at a predetermined position by connecting multiple rod bodies 141 and 142 in series. The length of the telescopic rod 140 can be changed, allowing the user to conveniently move the suitcase 100. Next, multiple wheels are arranged on the bottom of the suitcase body 110, and these wheels consist of two front wheels 151 and two rear wheels 152, but the present invention is not limited to this. In this way, each front wheel 151 and each rear wheel 152 rotates, allowing the suitcase 100 to move smoothly when it is pulled.

[0013] In the example shown in Figure 2, the upper edge 121 of the front cover 120 in this embodiment is lower than the upper edge 112 of the suitcase body 110. The overall thickness D of the suitcase 100 is defined as the distance from the outer surface of the front cover 120 to the back surface of the suitcase body 110. Based on the direction of thickness D, the thickness of the suitcase body 110 is d1, the thickness of the front cover 120 is d2, and d1 > 5d2. The suitcase body 110 has an attachment area 113 on the surface of a side edge perpendicular to the thickness direction, which serves as the attachment position for the lock 130. The attachment area 113 is located away from the center line 114 of the suitcase body 110 and adjacent to the front cover 120. In other words, the distance between the attachment area 113 and the outer surface of the front cover 120 is shorter than the distance between the attachment area 113 and the back surface of the suitcase body 110. The lock 130 is attached to the mounting area 113, and its operating part 131 is exposed to the mounting area 113. In other words, the distance from the lock 130 to the outer surface of the front cover 120 is shorter than the distance from the lock 130 to the underside of the suitcase body 110.

[0014] Returning to Figure 1, this embodiment further includes a suitcase frame 200 and a front cover frame 300. The suitcase frame 200 consists of at least one rigid frame and is attached to the periphery of the opening of the storage space 111 of the suitcase body 110. The front cover frame 300 consists of at least one rigid frame and is attached to one side of the front cover 120. Specifically, the concave ring portion 115 is formed on the surface of the suitcase body 110 and is located on the outer circumference of the opening of the storage space 111, and the suitcase frame 200 is attached to the concave ring portion 115. In this way, when the opening of the storage space 111 of the suitcase body 110 is covered by the front cover 120, the front cover frame 300 is tightened to the suitcase frame 200. A predetermined number of connecting members 400 are arranged between the front cover 120 and the suitcase body 110, allowing the front cover 120 to rotate relative to the suitcase body 110. Each connecting member 400 can connect the suitcase frame 200 and the front cover frame 300, the front cover 120 and the suitcase body 110, the front cover 120 and the suitcase frame 200, and the front cover frame 300 and the suitcase frame 200. In this way, all combinations of the front cover frame 300 and the front cover 120 are rotatable relative to the suitcase body 110.

[0015] Referring to Figure 3, a portion or part of the suitcase frame 200 has a through hole 201 through which it passes. The lock 130 further comprises a lock mounting portion 132 and at least one lock plate 133. The lock mounting portion 132 is connected to the operating portion 131 and is located inside the suitcase body 110, and the lock mounting portion 132 is located on one side of the through hole 201 of the suitcase frame 200. The lock plate 133 is attached to the front cover frame 300. Referring to Figure 4, when the suitcase body 110 is covered with the front cover 120, the lock plate 133 passes through the through hole 201 and connects to the lock mounting portion 132 of the lock 130. In addition, since both the front cover frame 300 and the suitcase frame 200 are hidden within the concave ring portion 115, the front cover frame 300 and the suitcase frame 200 are less likely to be forcibly moved.

[0016] Referring to FIG. 5, the front cover 120 according to this embodiment rotates in combination with the connecting member 400. The connecting member 400 is a first unit 401 attached to the front cover 120. From one side of the first unit 401, there is a first unit 401 with a stopper 402 extended, and a second unit 403 attached to the suitcase body 110 and the first unit 401 and connected, for example, by bolts. One side of the second unit 403 has a second unit 403 with a convex portion 404. More specifically, one side of the stopper 402 of the first unit 401 has an extension portion 405 for attachment to the front cover 120 or the front cover frame 300, and the second unit 403 has an extension portion 406 for attachment to the suitcase frame 200 or the suitcase body 110. It should be noted that the convex portion 404 is located at a point on the rotation path of the stopper 402. In this way, when the combination of the front cover 120 and the first unit 401 rotates to be opened to a predetermined angle, the stopper 402 abuts against the convex portion 404 to prevent the front cover 120 from rotating too much. The range of the opening angle of the front cover 120 according to this embodiment does not exceed 135°, and the optimal opening angle ranges between 95° and 120°.

[0017] The lock 130 according to this embodiment has a quadrilateral lock structure shown in FIG. 2, but the present invention is not limited thereto. In the example of FIG. 6, as shown in the figure, a circular lock 135 can similarly achieve the purpose and effect of the present invention. Similarly, all other locks applicable to the suitcase 100 are modifications and variations of this embodiment.

[0018] As described above, the suitcase frame 200 and the front cover frame 300 according to the present invention are composed of a hard material having appropriate hardness, and the hard material may include metal, plastic, or other similar materials. Next, a frame structure is adopted for the connection between the front cover and the suitcase body according to the present invention, and the fastener structure between the conventional front cover and the suitcase body is modified. And, the front cover frame and the suitcase frame according to the present invention are hidden in the concave ring portion of the suitcase body, making it difficult to forcibly open the frame, and improving the security effect of the suitcase. Also, the lock plate of the lock penetrates through the frame of the suitcase frame and is coupled to the lock installation portion, increasing the coupling strength between the lock and the suitcase body.

[0019] (Second Embodiment) Figures 7 to 8 show the configuration of a second preferred embodiment of the present invention. The structure of this embodiment is similar to that of the first embodiment. However, in this embodiment, the suitcase frame 601 and the front cover frame 602 are made of plastic material. The suitcase frame 601 is attached to the inner edge around the opening 501 on one side of the suitcase body 500. One side of the suitcase frame 601 has a through hole 603. The front cover frame 602 is attached to one side of the front cover 502, and the lock plate 504 protrudes from the front cover frame 602. Next, the suitcase frame 601 has at least a first hinge portion 605 on one side, and the front cover frame 602 has at least a second hinge portion 606 on one side, and at least one pin 607 passes through the first hinge portion 605 and the second hinge portion 606, thereby connecting the front cover frame 602 to the suitcase frame 601 and allowing the front cover 502 to open and close relative to the suitcase body 500. The combination of the first hinge portion 605, the second hinge portion 606, and the pin 607 is called a connecting member. When the suitcase body 500 is closed with the front cover 502, the lock plate 504 can pass through the through hole 603 and be connected to the lock 503. In addition to the integral molding of the structure of the suitcase frame 601 and the front cover frame 602, a multi-stage connection method may also be employed. In so-called multi-stage connections, each frame body has multiple frame rods interconnected, and a mortise and tenon structure may be used at the joints to form engagement or series connections. Similarly, the multi-stage connection method may be applied to the metal front cover frame and suitcase frame described above.

[0020] In the first embodiment, the suitcase body 110 has a rectangular structure, with two short sides 116 and two long sides 117 defined, the two short sides 116 being approximately perpendicular to the two long sides 117, the two short sides 116 facing each other, and the two long sides 117 facing each other, and connected to the opposing ends of the two short sides 116. In this embodiment, the lock 130 is a long lock, installed on one of the long sides 117 of the suitcase body 110, and its length is longer than half the length 117 of the suitcase body 110 (see Figure 2).

[0021] (Third embodiment) Figure 9 is a side view showing a suitcase according to a third preferred embodiment of the present invention. The structure according to this embodiment is similar to the structure of the first preferred embodiment. However, in this embodiment, the suitcase body 700 has two locks 701. The two locks 701 are short locks and are arranged on the long side 702 of one side of the suitcase body 700, spaced apart by a predetermined interval, and the length of each lock 701 is longer than half the length of the long side 702 of the suitcase body 700.

[0022] (Fourth embodiment) Figure 10 is a side view showing a suitcase according to a third embodiment of the present invention. The structure of this embodiment is similar to the structure of the first embodiment. However, in this embodiment, the suitcase body 800 has a lock 801, which is a short lock and is installed on the short side 802 of one side of the suitcase body 800, and the length of the lock 801 is shorter than half the length of the short side 802 of the suitcase body 800.

[0023] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and design modifications and the like are also included within the scope of the spirit of the present invention.
