Description

Technical Field

[0001] The present invention relates to a suitcase that does not adopt a stitching process, and particularly to an engaging type suitcase in which a case, a frame, and a lining are assembled by engagement.

Background Art

[0002] A suitcase is a box for carrying items when traveling on holidays or sightseeing overseas. With the increasing demand for use, various suitcases with different functions and designs are commercially available. Among them, current suitcases are mainly composed of two linings and two cases. The two linings are respectively attached inside the cases. One case is connected to the other case via a fastener, so that the two cases can be selectively opened and closed via the fastener. Furthermore, there are common fastener-equipped suitcases on the market that open and close via fasteners.

[0003] However, currently, fastener-equipped suitcases are usually those in which the lining and the fastener are sewn to the case. Therefore, it is not only inconvenient to assemble the two cases, the two linings, and the fastener, but also the assembly time for assembling the lining and the fastener to the case increases. Moreover, since the lining is sewn to the case, the lining cannot be separated from the case. Also, when there is dirt or damage on the lining, the user cannot easily replace the lining by himself / herself to perform cleaning work or repairs.

Summary of the Invention

[0004] The main object of the present invention is to improve the structural form of the suitcase so that the three structures of the case cover structure, the lining structure, and the fastener structure can be connected without adopting a stitching process, and the assembly time for connecting the three structures of the case cover structure, the lining structure, and the fastener structure can be relatively shortened.

[0005] To achieve the above object, the engaging type suitcase according to the present invention includes two case cover structures, two lining structures, and a fastener structure.

[0006] Each of the case cover structures is mainly composed of a frame and a case. The frame has an annular housing, and an inner stopper wall and an outer stopper wall are provided at one end of the annular housing. The inner stopper wall and the outer stopper wall are arranged at intervals from each other, so that an insertion space is formed between the inner stopper wall, the outer stopper wall and the annular housing. Also, a plurality of lining hooks are formed on the annular housing, and a plurality of locking blocks are formed on the outer stopper wall. Among them, the case is provided with a case bottom plate, a case surrounding plate, and a case space formed between the case bottom plate and the case surrounding plate. And the case surrounding plate has a plurality of locking holes into which the plurality of locking blocks are fitted. When the case surrounding plate is inserted into the insertion space, the inner stopper wall is accommodated in the case space, and the plurality of locking blocks on the outer stopper wall enter the plurality of locking holes on the case surrounding plate one by one.

[0007] Each of the lining structures has a lining body and a lining pressing strip. The lining body is connected to the lining pressing strip, is located inside the case space, and the lining pressing strip can be selectively engaged with or detached from a plurality of the lining hooks.

[0008] The fastener structure has two fastener tapes respectively connected to one of the two case cover structures, and a fastener head that can join or separate the two fastener tapes. By including an insertion tooth portion where the fastener tape is fixed inside the annular housing and a connection tooth portion that is exposed on the case cover structure, the two case cover structures can be connected to each other via the connection tooth portions of the two fastener tapes.

[0009] In a preferred embodiment, the outer stopper wall is deformable with respect to the annular housing, and when the case surrounding plate is inserted into the insertion space, the locking block is pressed by the case surrounding plate and is displaceable, so that the outer stopper wall can be deformed away from the inner stopper wall by the displaced locking block.

[0010] In addition, the locking block is provided with a locking block guide surface on the side away from the outer stopper wall, which can contact the case surrounding plate. The locking block guide surface guides the case surrounding plate between the locking block and the inner stopper wall so that the case surrounding plate can continue to move inside the insertion space. Among them, the lowest part of the locking block guide surface is the guide lower part, the highest part of the locking block guide surface is the guide upper part whose height position is higher than that of the guide lower part, the guide lower part is located inside the locking hole, and the guide upper part protrudes out of the locking hole and is located outside the case space.

[0011] The inner stopper wall has a plurality of internal partition plates, and the plurality of internal partition plates are arranged at intervals along the contour of the annular housing, so that an intermediate space is formed between two of the internal partition plates. Each intermediate space is aligned with one of the locking blocks one by one, and the guide upper part is located inside the intermediate space. Among them, the locking block forms a locking block groove recessed from the locking block guide surface and communicating with the insertion space.

[0012] Further, the annular housing is further provided with a baffle plate located above the plurality of lining hooks, and a clamping space is formed between the baffle plate and the plurality of lining hooks. The lining pressing strip is positioned inside the clamping space jointly by the baffle plate and the plurality of lining hooks. Among them, the width of the baffle plate is larger than the length of the lining hook, the baffle plate penetrates and forms a baffle plate through hole whose contour is larger than that of the lining hook, and the baffle plate through hole is aligned with the lining hook.

[0013] In addition, the engaging type suitcase further has a shielding structure including a shielding cover and a plurality of shielding hooks formed on the shielding cover. Some of the shielding hooks engage with the annular housing of one of the frames, and the remaining shielding hooks engage with the annular housing of the other frame, so that the shielding cover can shield some of the fastening tapes.

[0014] Among them, the shielding cover has two assembling parts arranged at intervals and a bending part located between the two assembling parts. Each of the assembling parts forms some of the shielding hooks, and the bending part is deformable so as to change the relative positions between the two assembling parts. On the outer side of the annular housing, a shielding groove is recessed and formed to accommodate the assembling part, and the depth of the shielding groove is greater than or equal to the thickness of the assembling part so that the assembling part does not protrude outside the annular housing.

[0015] Among them, a hook through hole is formed through the annular housing, and the shielding hook has an extension part located inside the hook through hole and an engaging part arranged intersecting with the extension part. The engaging part is located outside the hook through hole and is arranged offset in the hook through hole so as to be able to contact the inner side of the annular housing.

[0016] However, the extension part is deformable with respect to the shielding cover. When the shielding hook is inserted into the hook through hole, the engaging part abuts against the annular housing, so that the extension part is deformable so that the engaging part can enter the inside of the hook through hole. Among them, the shielding hook is provided with a hook guiding surface for introducing the shielding hook into the inside of the hook through hole on the engaging part.

[0017] Finally, the frame is injection molded with plastic onto the plurality of inserted tooth parts of the fastening tape.

[0018] In the present invention, since the fastener tapes of two fastener structures can be fitted into the frame of the case cover structure, the frame can cover the engaging tooth portions of the fastener tapes, and further the fastener tapes can be integrally formed with the frame. Also, both the case and the lining structure of the case cover structure can be selectively engaged with or detached from the frame, so that the assembly time for both the case and the lining structure to be assembled to the frame can be shortened. Moreover, since both the case and the lining structure are engaged with the frame, the three components of the case, the frame, and the lining structure are easily separable from each other, facilitating repair.

[0020] In order to more clearly, detailedly recognize and understand the structure, use and features of the present invention, preferred embodiments will be given and described in detail as follows with reference to the drawings.

[0021] Refer to FIGS. 1 and 2. The engaging type suitcase 1 according to the present invention mainly comprises two case cover structures 10, two lining structures 20, a fastener structure 30, and a shielding structure 40. Refer to FIGS. 2, 3, and 4. Each case cover structure 10 has two parts, namely a frame 11 and a case 12. Among them, the frame 11 has an annular housing 111 integrally moldable with the fastener structure 30. The annular housing 111 presents an annular form, and a plurality of lining hooks 112 and a baffle plate 113 with a height position different from that of the lining hooks 112 are provided inside it. The baffle plate 113 has a width larger than the length of the lining hooks 112 and is arranged at intervals on the plurality of lining hooks 112, so that a clamping space S1 is formed between the baffle plate 113 and the plurality of lining hooks 112. As shown in the figure, the baffle plate 113 is formed with a plurality of baffle plate through holes 113a whose contour is larger than that of the lining hooks 112. Each baffle plate through hole 113a communicates with the clamping space S1 and is aligned with one of the lining hooks 112 one by one. Refer to FIG. 5. The outside of the annular housing 111 is recessed from the outside to the inside to form a shielding groove 114 with a rectangular appearance, and the annular housing 111 is formed with a plurality of hook through holes 115 penetrating from the shielding groove 114 towards the inside of the annular housing 111. As shown in FIGS. 3 and 4, in addition, the lower end of the annular housing 111 extends to form an inner stopper wall 116 close to the lining hooks 112 and an outer stopper wall 117 surrounding the inner stopper wall 116. The inner stopper wall 116 is arranged at intervals inside the outer stopper wall 117, so that an insertion space S2 located below the annular housing 111 is formed between the inner stopper wall 116 and the outer stopper wall 117. The outer stopper wall 117 is deformable with respect to the annular housing 111 and extends towards the inside of the insertion space S2 to form a plurality of locking blocks 118.

[0022] Refer to FIGS. 3 and 4. In this embodiment, the inner stopper wall 116 of the frame 11 has a plurality of internal partition plates 116a, and the plurality of internal partition plates 116a are arranged at intervals along the contour of the annular housing 111 of the frame 11. Thus, two internal partition plates 116a respectively form an intermediate space 116b for communicating with the insertion space S2 of the frame 11, and each intermediate space 116b is aligned with one locking block 118 of the frame 11 on a one-to-one basis. In addition, the locking block 118 of the frame 11 is provided with a locking block guide surface 118a having an inclined form on the side away from the outer stopper wall 117, and a locking block groove 118b is formed which is recessed from the locking block guide surface 118a toward the outer stopper wall 117 and communicates with the insertion space S2. Among them, the lowest part of the locking block guide surface 118a is the guide lower part 118c, and the highest part of the locking block guide surface 118a is the guide upper part 118d whose height position is higher than that of the guide lower part 118c, and the guide upper part 118d is located inside the intermediate space 116b.

[0023] Refer to FIGS. 2 and 3. The case 12 of the case cover structure 10 has a case surrounding plate 121 whose appearance is in an annular form on different sides and a case bottom plate 122 whose appearance is in a rectangular form. One end of the case surrounding plate 121 is formed to surround the case opening 123, and the case surrounding plate 121 is formed with a plurality of locking holes 124 penetrating therethrough in the vicinity of the case opening 123. Among them, the case bottom plate 122 is provided at the other end of the case surrounding plate 121, is arranged at intervals from the case opening 123, and jointly forms a case space 125 between the case bottom plate 122 and the case surrounding plate 121 which not only communicates with each locking hole 124 but also communicates with the case opening 123.

[0024] Refer to FIG. 6A. The case enclosure plate 121 of the case 12 is inserted into the insertion space S2 of the frame 11, and thus moves inside the insertion space S2 and abuts against the locking block guide surface 118a of the locking block 118. When the case enclosure plate 121 contacts the locking block guide surface 118a, the locking block guide surface 118a can introduce the case enclosure plate 121 between the locking block 118 and the inner stopper wall 116, so that the case enclosure plate 121 can continue to move inside the insertion space S2 along the locking block guide surface 118a, and furthermore, the tip of the case enclosure plate 121 gradually approaches the guide high portion 118d of the locking block guide surface 118a. Among them, in the process of the case enclosure plate 121 moving along the locking block guide surface 118a, the locking block 118 is pressed by the case enclosure plate 121 and is displaceable with respect to the annular housing 111 of the frame 11, and the outer stopper wall 117 of the frame 11 can be deformed in a direction away from the inner stopper wall 116 through the displaced locking block 118, so that the guide high portion 118d of the locking block guide surface 118a can contact the outer surface of the case enclosure plate 121. Next, as shown in FIG. 6B, the case enclosure plate 121 continues to move inside the insertion space S2, bringing the locking hole 124 of the case 12 close to the locking block 118. When the locking block 118 is aligned with the locking hole 124, the inner stopper wall 116 is located inside the case space 125 of the case 12, and the outer stopper wall 117 deforms into its original shape contour, so that each locking block 118 is engaged with one locking hole 124 respectively. In this embodiment, when the locking block 118 is engaged with the locking hole 124, the guide low portion 118c of the locking block guide surface 118a is located inside the locking hole 124, and a part of the locking block guide surface 118a is also located inside the locking hole 124. At the same time, the guide high portion 118d protrudes out of the locking hole 124 and is located outside the case space 125.

[0025] Refer to FIGS. 2, 7 and 8. Each lining structure 20 has a lining pressing strip 21 presenting an annular form and a lining body 22 made of a soft material. The lining body 22 is provided with a lining opening end 221 at both opposite sides and a lining closing end 222 arranged at intervals from the lining opening end 221. The lining body 22 extends from the lining opening end 221 towards the lining closing end 222 to form a lining side portion 223. The lining opening end 221 surrounds the lining pressing strip 21 and is sewn to the lining side portion 223, so that the lining opening end 221 can cover the lining pressing strip 21, and further the lining body 22 can be connected to the lining pressing strip 21.

[0026] Refer to FIGS. 9A and 9B. The lining pressing strip 21 of the lining structure 20 can be selectively engaged with or removed from a plurality of lining hooks 112 of the frame 11. When the lining pressing strip 21 is engaged with the plurality of lining hooks 112, the lining body 22 of the lining structure 20 is located inside the case space 125 of the case 12. The lining pressing strip 21 and the plurality of lining hooks 112 jointly sandwich the lining side portion 223 of the lining body 22, and at the same time, the lining pressing strip 21 is located inside the clamping space S1. Among them, the width of the baffle plate 113 is larger than the width of the lining pressing strip 21. Further, as shown in FIG. 9B, when looking at the baffle plate 113 from top to bottom, the baffle plate 113 can shield the whole lining pressing strip 21, and the lining pressing strip 21 is jointly positioned inside the clamping space S1 by the plurality of lining hooks 112 and the baffle plate 113.

[0027] Refer to FIGS. 2, 10 and 11. The fastener structure 30 is located between the frames 11 of the two case cover structures 10 and has two fastener tapes 31 and a fastener head 32. Among them, a plurality of connecting teeth 311 are provided at intervals on one side of each fastener tape 31, and a plurality of fitting teeth 312 are provided at intervals on the side of each fastener tape 31 away from the connecting teeth 311. In this embodiment, the frame 11 of the case cover structure 10 can be integrally formed with the fitting teeth 312 of the fastener tape 31 by injection molding plastic onto the plurality of fitting teeth 312 of the fastener tape 31. As shown in the figure, when the frame 11 is integrally formed with the fastener tape 31, the plurality of fitting teeth 312 of each fastener tape 31 are respectively fitted into the annular housing 111 of one frame 11, so that the annular housing 111 can cover the plurality of fitting teeth 312, and further the connecting teeth 311 are exposed on the annular housing 111. Also, since the fastener head 32 can mesh the connecting teeth 311 of one fastener tape 31 with the connecting teeth 311 of the other fastener tape 31, the two case cover structures 10 can be connected to each other via the connecting teeth 311 of the two fastener tapes 31.

[0028] Refer to FIGS. 2 and 12. The shielding structure 40 mainly consists of a shielding cover 41 and a plurality of shielding hooks 42. The shielding cover 41 has two assembly parts 411 arranged at intervals and a bending part 412 located between the two assembly parts 411. The thickness of the assembly part 411 is not more than the depth of the shielding groove 114 of the frame 11, and the bending part 412 is deformable to change the relative positions between the two assembly parts 411. Among them, some of the shielding hooks 42 are formed on one assembly part 411, and the remaining shielding hooks 42 are formed on the other assembly part 411. As shown in the figure, each shielding hook 42 has an extension part 421 formed by extending from the assembly part 411 and an engaging part 422 arranged intersecting with the extension part 421, thus presenting an L-shaped external form. Among them, the extension part 421 is deformable relative to the assembly part 411, and the engaging part 422 is provided with a hook guiding surface 422a presenting an inclined form.

[0029] Refer to FIGS. 13A, 13B and 13C. Since the shielding structure 40 is connected to the frames 11 of the two case cover structures 10, first, as shown in FIG. 13A, the shielding structure 40 can bring the hook guide surface 422a of the shielding hook 42 into contact with the periphery of the hook through-hole 115 of the frame 11 in proximity to the frames 11 of the two case cover structures 10. Next, as shown in FIG. 13B, when the shielding structure 40 continues to be in proximity to the two frames 11, the shielding hook 42 moves in the inclined direction of the hook guide surface 422a. Since the extending portion 421 of the shielding hook 42 is deformable, both the extending portion 421 and the engaging portion 422 of the shielding hook 42 can enter into the hook through-hole 115, whereby the hook guide surface 422a can introduce the shielding hook 42 into the hook through-hole 115. Finally, as shown in FIG. 13C, when the engaging portion 422 moves outside the hook through-hole 115, the extending portion 421 deforms into the original shape contour, so that the engaging portion 422 is arranged with a displacement in the hook through-hole 115 and can further contact the inside of the annular housing 111. At the same time, the two assembling portions 411 of the shielding cover 41 are respectively located inside the shielding grooves 114 of one frame 11, so that some of the shielding hooks 42 engage with the annular housing 111 of one frame 11, and the remaining shielding hooks 42 engage with the annular housing 111 of the other frame 11. Thus, the bent portion 412 of the shielding cover 41 can shield some of the fastening tapes 31. In this embodiment, when the two assembling portions 411 are respectively located inside one shielding groove 114, since the depth of the shielding groove 114 is not less than the thickness of the assembling portion 411, the assembling portion 411 does not protrude outside the annular housing 111.

[0030] Refer to FIG. 14. After the shielding structure 40 is connected to the frames 11 of the two case cover structures 10, one case cover structure 10 can be turned relative to the other case cover structure 10 through the bent portion 412 of the shielding cover 41. Thus, the bent portion 412 is deformable to change the relative positions between the two assembling portions 411 of the shielding cover 41.

[0031] The above-described embodiments are merely for explaining the present invention and do not limit it. Without departing from the scope of the present invention, various simple modifications and decorations made by those skilled in the art based on the claims for utility model registration and the description of the utility model should all be included in the following claims for utility model registration.
