User operation is simple. The self-locking structure is built into the housing, effectively improving the overall aesthetics of the luggage.

Description

Technical Field

[0001] The present invention relates to the field of luggage, and in particular to a self-locking reinforced handle for luggage and a self-locking method thereof. Background Art

[0002] In the field of luggage, in order to facilitate the use of luggage, handles are generally provided on the top and sides of the luggage (especially trolley cases), such as Figure 1 As shown, the handle body 1 is generally locked and installed together with the case shell and frame. During the use of the case, the user often needs to lift or put down the case by the handle. During the lifting process, the case will be repeatedly subjected to the lifting force from the handle. In the manufacturing of the case, whether the case is made of woven material, plastic material or metal material, due to the weight of the case and the limitation of manufacturing cost, thick materials are generally not selected for the case shell. This makes the overall strength of the case shell weak, and the area frequently subjected to the lifting force has a particularly weak resistance to deformation. When the lifting force is too large, the case shell and frame in the handle installation area will be deformed, and the concave and convex interlocking structures of the frame on both sides of the case shell are also prone to bending and interlocking, resulting in irreversible plastic deformation of the case shell and frame. This deformation eventually affects the normal opening and closing of the case, making the case unusable.

[0003] In order to avoid the phenomenon that the box shell and frame are damaged due to excessive pulling force, the current common solution is to add a lock component 2 (such as Figure 2 As shown in the figure, the locking force provided by the lock component is used to enhance the degree of engagement between the two upper frames of the box shell, thereby enhancing the anti-lifting strength of the bag and suppressing deformation caused by repeated lifting of the bag. However, this method is prone to the following defects in actual application: (1) The cost of the bag is high. Since the lock component is a relatively sophisticated component among the various components of the bag, its structure is relatively complex and the cost is also high, which increases the manufacturing cost of the bag. At the same time, since the lock component structure is relatively sophisticated, it needs to be repeatedly debugged during production and assembly to ensure its good functionality. Therefore, increasing the number of lock components on the bag will also increase the labor cost of bag manufacturing. (2) When there are many lock components on the bag, the user needs to repeatedly open and close each lock component at different positions during the use of the bag, which is inconvenient for the user to use the bag and the user experience is poor. (3) Multiple lock components are exposed on the outer wall of the bag, which easily makes the appearance of the bag less concise and affects the aesthetics of the bag. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a self-locking reinforced handle for luggage. When the handle is pulled, a self-locking force-bearing structure is formed inside the box shell, which effectively reduces the force on the box shell and the frame, making it easy for users to operate. At the same time, its self-locking structure is built into the box shell, which can effectively improve the aesthetics of the overall structure of the luggage.

[0005] Another object of the present invention is to provide a self-locking method for a self-locking reinforced handle for a bag.

[0006] The technical solution of the present invention is a self-locking reinforced handle for luggage, comprising a handle body, a movable hook assembly, and a fixed hook assembly. The handle body is disposed outside a first housing of the luggage, with movable hook assemblies disposed at each end of the handle body, each movable hook assembly extending into the interior of the first housing. Two sets of fixed hook assemblies are disposed inside a second housing, each movable hook assembly engaging with a fixed hook assembly. When the handle body is pulled, each movable hook assembly forms a self-locking structure with the corresponding fixed hook assembly. In this structure, the handle body can generally be a handle body commonly used in existing luggage, and has a certain degree of elasticity to facilitate user lifting. When the handle body is pulled, the pulling force shortens the distance between its ends, thereby driving the movable hook assembly to engage with the fixed hook assembly, forming a self-locking structure. When the handle body returns to its original state, the movable hook assembly also returns to its original state, thereby unlocking the handle. During this process, the self-locking structure formed between the movable hook assembly and the fixed hook assembly has the function of strengthening the strength of the box shell and frame in the handle body installation area, forming a force structure on the self-locking structure, thereby reducing the force on the box shell and frame.

[0007] In the bag, a first frame is provided at the opening of the first shell, a second frame is provided at the opening of the second shell, and the junction of the movable hook assembly and the fixed hook assembly is located below the bite of the first frame and the second frame.

[0008] The two groups of fixed hook assemblies are symmetrically arranged along the center line of the luggage, and the two groups of movable hook assemblies are also symmetrically arranged along the center line of the luggage; along the center line of the luggage to both sides, the movable hook assemblies slide on the outside of the fixed hook assemblies, or the movable hook assemblies swing on the inside of the fixed hook assemblies.

[0009] The fixing hook assembly is installed in an L-shape on the inner side of the second box shell, and includes a fixing hook and a fixing hook mounting block. The fixing hook is fixedly installed by the fixing hook mounting block, and the hook portion of the fixing hook is arranged parallel to the second box shell.

[0010] As a preferred solution, the movable hook assembly includes a connecting member and a sliding hook, one end of the connecting member is connected to the handle body, and the other end of the connecting member is provided with a sliding hook, the hook portion of the sliding hook is arranged parallel to the first box shell, and the hook portion of the sliding hook and the hook portion of the fixed hook are located in the same plane facing each other.

[0011] The movable hook assembly also includes a sliding hook auxiliary member, which is mounted on the inner side of the first housing. The movable hook auxiliary member has a T-shaped or L-shaped through-slot, into which the connecting member and the sliding hook extend and slide. Specifically, the connecting member enters the through-slot from the interface between the sliding hook auxiliary member and the first housing, and the sliding hook then extends from the through-slot on the side of the sliding hook auxiliary member. The connecting member and the sliding hook also form an L-shape.

[0012] As another preferred embodiment, the movable hook assembly includes a connecting member, a rack, a gear and a swinging hook, one end of the connecting member is connected to the handle body, the other end of the connecting member is provided with a rack, one end of the rack is also provided with a spring, one end of the swinging hook is provided with a gear and is installed on the inner side of the first box shell through the gear, and one side of the rack is engaged with the gear; the hook portion of the swinging hook is arranged parallel to the first box shell, and when a self-locking structure is formed between the movable hook assembly and the fixed hook assembly, the hook portion of the swinging hook and the hook portion of the fixed hook are located in the same plane facing each other.

[0013] The movable hook assembly also includes a swing hook auxiliary member, which is mounted on the inner side of the first case shell. The swing hook auxiliary member is a box-shaped structure with an opening on the side. The connecting member extends into the swing hook auxiliary member after passing through the first case shell. The rack, gear, and swing hook are located within the swing hook auxiliary member. When a self-locking structure is formed between the movable hook assembly and the fixed hook assembly, the swing hook extends from the opening on the side of the swing hook auxiliary member. In this structure, it is also possible to configure one swing hook auxiliary member for each set of movable hook assemblies, or to configure one swing hook auxiliary member between two sets of movable hook assemblies, depending on the actual situation of the luggage. On the one hand, the swing hook auxiliary member can shield the rack, gear, and swing hook, preventing these components from being exposed and easily damaged. On the other hand, the opening on its side can provide a stable motion trajectory for the swinging of the swing hook, ensuring stable cooperation between the swing hook and the fixed hook.

[0014] A handle seat is provided at the joints between the two ends of the handle body and the first box shell. The connecting piece in the movable hook assembly passes through the handle seat and the first box shell in sequence and then extends into the first box shell.

[0015] The self-locking method of the self-locking reinforced handle for luggage of the present invention is as follows: when the handle body is pulled, the handle body arches toward the center, thereby shortening the distance between the two ends of the handle body, driving the movable hook assemblies at the two ends to move closer until each movable hook assembly engages with the corresponding fixed hook assembly, forming a self-locking structure; when the handle body is released, the handle body returns to its original state, and the distance between the two ends of the handle body becomes longer, driving the movable hook assemblies at the two ends to move outward, and each movable hook assembly separates from the corresponding fixed hook assembly, thereby releasing the self-locking structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The self-locking reinforced handle used in this luggage will form a self-locking force-bearing structure inside the luggage shell when it is lifted, which specifically improves the rigidity of the handle body installation area and increases the interlocking strength of the frame. The strengthening effect is significant, effectively reducing the force on the luggage shell and frame, and preventing the luggage shell and frame from being damaged by tension, which would affect the reuse of the luggage. At the same time, the user can operate it easily, without having to repeatedly open or close the luggage in different positions.

[0018] In the self-locking reinforced handle used in this luggage, the elastic deformation of the handle body itself is used to drive the movable hook component to move, forming a self-locking structure with the fixed hook component or releasing the self-locking structure. Its structure is simple and ingenious, but it operates stably, and it can also effectively simplify the structure of the luggage and reduce the overall weight of the luggage itself.

[0019] The main components of the self-locking reinforced handle used in this luggage are all installed on the inner side of the case shell to form a hidden structure, which can effectively simplify the appearance structure of the luggage and improve the aesthetics of the overall structure of the luggage.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the examples, but the embodiments of the present invention are not limited thereto.

[0037] Example 1

[0038] This embodiment is a self-locking reinforced handle for luggage, such as Figures 3 to 5As shown, the bag comprises a handle body 1, a movable hook assembly and a fixed hook assembly. The handle body is arranged on the outside of the first shell 3 of the bag, and movable hook assemblies are respectively provided at both ends of the handle body. Each movable hook assembly extends into the inside of the first shell. Two sets of fixed hook assemblies are provided on the inside of the second shell 4 of the bag, and each set of movable hook assemblies cooperates with a set of fixed hook assemblies. When the handle body is pulled, each movable hook assembly forms a self-locking structure with the corresponding fixed hook assembly (as shown in FIG. Figure 4 or Figure 5 (As shown). In this structure, the handle body can generally adopt the handle bodies commonly used in existing luggage, which has a certain degree of elasticity, making it convenient for users to lift. When the handle body is pulled, the pulling force shortens the distance between the two ends of the handle body, thereby driving the movable hook assembly to engage with the fixed hook assembly, forming a self-locking structure. When the handle body returns to its original state, the movable hook assembly also returns to its original state, thus unlocking. During this process, the self-locking structure formed between the movable hook assembly and the fixed hook assembly functions to strengthen the case shell and frame in the area where the handle body is installed, forming a stress-bearing structure on the self-locking structure, thereby reducing the stress on the case shell and frame.

[0039] like Figure 3 or Figure 4 As shown, in the case, a first frame 5 is provided at the opening of the first shell, and a second frame 6 is provided at the opening of the second shell. The junction of the movable hook assembly and the fixed hook assembly is located below the intersection of the first and second frames. The two sets of fixed hook assemblies are symmetrically arranged along the midline of the case, and the two sets of movable hook assemblies are also symmetrically arranged along the midline of the case. Along the midline of the case, the movable hook assemblies slide outside the fixed hook assemblies or swing inside the fixed hook assemblies.

[0040] like Figure 3 or Figure 4 As shown, the fixing hook assembly is installed in an L-shape on the inner side of the second box shell, including a fixing hook 7 and a fixing hook mounting block 8. The fixing hook is fixedly installed by the fixing hook mounting block, and the hook portion of the fixing hook is arranged parallel to the second box shell.

[0041] The movable hook assembly includes a connector 9, a sliding hook 10, and a sliding hook auxiliary member 11. One end of the connector is connected to the handle body, and the other end is provided with a sliding hook. The hook portion of the sliding hook is parallel to the first housing shell, and the hook portion of the sliding hook and the hook portion of the fixed hook are located in the same plane. The sliding hook auxiliary member is mounted on the inside of the first housing shell. The movable hook auxiliary member has a T-shaped or L-shaped through-slot, into which the connector and the sliding hook extend and slide. Specifically, the connector enters the through-slot from the interface between the sliding hook auxiliary member and the first housing shell, and the sliding hook then extends from the through-slot located on the side of the sliding hook auxiliary member, forming an L-shape between the connector and the sliding hook.

[0042] like Figure 6 or Figure 7 As shown, a handle seat 12 is provided at the junction of both ends of the handle body and the first box shell. The connecting member in the movable hook assembly passes through the handle seat and the first box shell in sequence and then extends into the first box shell.

[0043] The self-locking method of the self-locking reinforced handle for the above-mentioned luggage is: when the handle body is pulled, Figure 8 and Figure 9 As shown in FIG, since the handle body is arched toward the center, the distance between the two ends of the handle body is shortened, driving the movable hook components at both ends to move closer until each movable hook component is engaged with the corresponding fixed hook component to form a self-locking structure; when the handle body is loosened, as shown in FIG. Figure 6 and Figure 7 As shown, the handle body returns to its original shape, and the distance between its ends increases, driving the movable hook assemblies at both ends to move outward. Each movable hook assembly separates from the corresponding fixed hook assembly, releasing the self-locking mechanism. The specific principle is as follows: when the first and second shells are closed, the corresponding first and second frames are locked together. When the user pulls the handle body upward, the handle body gradually bends and deforms due to its own elasticity. The connecting members at both ends of the handle body drive the sliding hooks toward the fixed hooks and engage with them. After the sliding hooks engage with the fixed hooks, they restrict the first and second frames, inhibiting the tendency for them to separate, thereby strengthening the mounting area of the handle body. By strengthening this area, the handle body is less likely to pull the bag and deform, improving the bag's resistance to deformation. When the user releases the handle body, the handle body gradually rebounds and returns to a straight state. At this time, the sliding hooks gradually separate from the fixed hooks as the handle body rebounds, releasing the self-locking mechanism.

[0044] Example 2

[0045] This embodiment is a self-locking reinforced handle for luggage. Compared with the first embodiment, the difference is that: Figures 10 to 15As shown, the movable hook assembly includes a connector 9, a rack 13, a gear 14, a swing hook 15, and a swing hook auxiliary member 16. One end of the connector is connected to the handle body, and the other end of the connector is provided with a rack. The end of the rack near the centerline of the bag is also provided with a spring 17. A gear is provided at one end of the swing hook and is mounted on the inside of the first case shell through the gear. One side of the rack engages with the gear. The hook portion of the swing hook is arranged parallel to the first case shell. When the movable hook assembly and the fixed hook assembly form a self-locking structure, the hook portion of the swing hook and the hook portion of the fixed hook face each other and lie in the same plane. The swing hook auxiliary member is mounted on the inside of the first case shell. The swing hook auxiliary member is a box-shaped structure with an opening on the side. The connector passes through the first case shell and extends into the swing hook auxiliary member. The rack, gear, and swing hook are located within the swing hook auxiliary member. When the movable hook assembly and the fixed hook assembly form a self-locking structure, the swing hook extends from the opening on the side of the swing hook auxiliary member. In this structure, depending on the actual needs of the luggage, a swing hook auxiliary member can be configured for each set of movable hook assemblies, or a swing hook auxiliary member can be configured between two sets of movable hook assemblies. The swing hook auxiliary member not only shields the rack, gear, and swing hook from exposure and possible damage, but also provides a stable motion trajectory for the swing hook through its side opening, ensuring stable cooperation between the swing hook and the fixed hook.

[0046] When the self-locking reinforced handle of this embodiment is used, its principle is as follows: taking the top handle of a bag as an example, when the first box shell and the second box shell are closed, the corresponding first frame and the second frame are embedded and fixed; Figure 14 and Figure 15 As shown, when the user pulls the handle body upward, the handle body gradually bends and deforms, and the connecting pieces at both ends of the handle body push the racks toward the center line of the bag, compressing the springs. The racks drive the gears to rotate, and the gears drive the swing hooks to swing and gradually move toward the fixed hooks, engaging with the fixed hooks. After the swing hooks engage with the fixed hooks, they restrict the first frame and the second frame, inhibiting the tendency for them to separate, thereby strengthening the strength of the handle body installation area. By strengthening the strength of this area, the occurrence of the handle body pulling and deforming the bag is reduced, thereby improving the bag's ability to resist deformation from being pulled. Figure 12 and Figure 13 As shown, when the user releases the handle body, the handle body gradually rebounds and returns to a straight state, the spring at the end of the rack releases the compression force, pushing the rack to drive the gear and the swing hook to reset, and the swing hook gradually separates from the fixed hook as the handle body rebounds, releasing the self-locking.

[0047] As described above, the present invention can be better implemented. The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made based on the content of the present invention are covered by the scope of protection required by the claims of the present invention.
